Williams, Omari Nekoro. "Retail Distribution Within the New York City Organic Cacao Market." ScholarWorks, 2015. https://scholarworks.waldenu.edu/dissertations/476.
Full textAbstract:
The purpose of this multiple case study was to explore strategies small physical commodities firm owners need to establish a distribution channel within the commodities market to enhance profits. The general business problem was that importing physical commodities from emerging markets was not profitable. The specific business problem was some small physical wholesale commodities firm managers lacked strategies to establish distribution channels for imported commodities. The information presented in this study is important to suppliers, manufacturers, distributors, and retailers of organic cacao products to identify strategies to enhance their distribution channels. Disruptive innovation and the theory of constraints grounded the conceptual framework to relate ideas presented in this study. The central research question guiding the study concerned strategies small physical wholesale commodities firm owners used to establish distribution channels within the commodities market. Participants included 6 small business owners who gave recorded responses during in-depth, face-to-face interviews. The 6 interview recordings were transcribed, then coded and interpreted. Data analysis revealed 6 themes, which included price point strategy, B2B relationships, differentiation, strategic locations, sufficient operating capital, and customer relationships. Enhancing profits in the distribution channels of small organic cacao companies requires a holistic approach in the New York City area. The social implications of this study may draw attention to organic cacao, which is a healthy alternative to confectionery chocolate. Strategies introduced to enhance profits may increase economic growth in the local communities in the New York Tri-State area.

This dissertation undertakes a comparative and developmental analysis of Frank Lloyd Wright's community scale planning projects executed in the wake of Broadacre City during the decade of the Second World War (1938 - 1948). These include the Sun-Top Homes built in Ardmore Pennsylvania, the Usonia I project for East Lansing Michigan, the Pittsfield Worker Housing project designed for western Massachusetts, the master plan for Circle Pines summer camp in central Wisconsin, and three partially built circular lot subdivisions, Galesburg Country Homes near Galesburg Michigan, Parkwyn Village in Kalamazoo Michigan, and Usonia Homes in Pleasantville New York. Through this study of seven planning projects Wright's thinking can be seen moving from a tradition of viewing the settlement as a 'constructed whole' to a design philosophy that approached nature as an a-priori, all embracing context. In these works he explored the relationship of the natural to the manmade by inventing patterns which allow neither the site nor the geometry of the plan to assume cognitive priority. One's perception of the relationship between the individual and the group comes to be crossed with one's perception of the character of the landscape in ways that extend an American hermeneutical tradition of self and landscape into the modem era. Building on the method of Emerson, and especially on the explorations of Thoreau and Whitman, Wright sought to redefine the ever-present tension between the individual and the democratic group in terms of a symbolic interaction of self and landscape that lies at the heart of the American myth of nature. His involvement with self, with nature, and with perceptions of community as indicated here suggests an alternative to traditional American suburban models, as well as to the European inspired hOUSing ideas coming into this country in the post-war period.

Full textAbstract:
Lakes in Hanoi play an important role in local human life. However, along with the economic and social development, some urban lakes have been polluted, especially organic pollution. This paper presents the monthly survey results for organic pollution assessment of ten selected lakes in Ha Noi city: the Ho Tay, Truc Bach, Thien Quang, Ba Mau, Bay Mau, Hoan Kiem, Ngoc Khanh, Giang Vo, Thanh Cong and Thu Le lakes during the period from March 2014 to February 2015. The survey results showed that the Ba Mau lake was organic polluted at level IV whereas other lakes were contaminated by organic matters at level III. Organic pollution may come from both autochthonous and allochthonous sources. Compared with the results of previous studies, the water quality of 10 lakes in the period from March 2014 to February 2015 has been improved thank for the recent application of some positive solutions for lake environmental protection.Hệ thống hồ ở Hà Nội đóng vai trò quan trọng trong đời sống của người dân.

Full textAbstract:
This thesis is a study of four cities and their city-plans. The purpose of the paper is to understand similarities and differences between cities in northern Greece during the Classical period. This is done with a comparative method and Kevin Lynch’s theory of the image of the city. The method and the theory are the foundation for the study. The research question used to be able to fulfil the purpose of the paper is Which similarities and differences exist in the construction of Classical cities in northern Greece and why does these similarities and differences exist? The general plans of the chosen cities are studied, not individual buildings and remains. Aspects such as roads, the placement of city walls, agora, public buildings, and residential areas are compared in the paper. The four cities that were studied in the paper were Amphipolis, Olynthus, Pella, and Thasos. All located in Macedonia or on Chalcidice and Thasos. They were selected based on a few criteria. All were known cities from the Classical period, had been excavated to quite a large extent and were not only religious places or burial grounds. The cities are not exact copies of each other. Olynthus and Pella are built after the Hippodamian plan, but Amphipolis and Thasos are built over time with an organic city-plan. Buildings, structures, and central places are the same in the different cities but how the cities are structured and how buildings are placed vary. The terrain, the landscape, traditions, philosophical ideas could all be part of the cause why the four compared cities have been structured differently. The land the cities have been built on vary which affect how a city can be planned and built. The result of the thesis is that the cities in northern Greece have similarities in what types of buildings and structures can be found in them. How the city is structured and organized are the differences in the city-plans and to which degree depends on multiple factors.

A segurança alimentar e as consequências provocadas no meio ambiente
pelo modo de produção atual de alimentos, baseado no uso de agrotóxicos e alto
grau de mecanização, têm se tornado temas de debates na comunidade
internacional. Diante desse cenário, o modelo de produção orgânico, que tem na
isenção de insumos químicos e na preservação do ecossistema seus valores
fundamentais, surge como uma proposta alternativa. O mercado de produtos
orgânicos apresentou crescimento considerável na última década no Brasil. O
objetivo deste trabalho foi levantar os motivos que influenciam consumidores na
sua decisão de compra de produtos orgânicos. Foi utilizado um método de
pesquisa do tipo survey, de cunho exploratório e descritivo, com amostra de 44
indivíduos, frequentadores de feiras e de lojas especializadas. A coleta de dados se
deu através de um formulário com escalas desenvolvidas para indicar os possíveis
fatores que influenciam a compra de produtos orgânicos no Rio de Janeiro, a
partir de revisão bibliográfica. As ferramentas estatísticas utilizadas para o
tratamento dos dados foram a análise descritiva e o teste de diferença de médias
entre consumidores assíduos e não regulares, com ou sem filhos, considerando
diferentes faixas etárias. Os resultados apontam que as principais motivações para
a compra de orgânicos são a isenção de agrotóxicos e os benefícios à saúde do
consumidor e de sua família. Porém, preço e proximidade das feiras às residências
dos consumidores surgiram como fatores relevantes para o desenvolvimento deste
mercado.Food safety and the impact in the environment caused by the current food production based on the use of pesticides and high degree of mechanization have become topics of discussion in the international community. Given this scenario, the organic production model, which has chemical inputs and exemption in the preservation of the ecosystem their fundamental values, emerges as an alternative proposal. The organic products market showed considerable growth over the past decade in Brazil. The aim of this work was to raise the reasons which influence consumers to purchase organic products. It was used a research method called survey, of exploratory and descriptive nature, with 44 individuals, fairs and specialty stores visitors. Data collection took place through a form with scales developed to indicate the possible factors influencing purchase of organic products in Rio de Janeiro, from literature review. The statistical tools used for the processing of data were descriptive analysis and testing of average difference between regular and non-regular consumers, with or without children, considering different age groups. The results show that the main reasons for buying organic are the exemption of pesticides and the benefits to the health of the consumer and of his family. However, price and proximity of the fairs to consumer homes have emerged as important factors for the development of this market.

Full textAbstract:
Black carbon (BC) and polycyclic aromatic hydrocarbons (PAHs) are two atmospheric pollutants produced by motor vehicles using carbonaceous fuels. As a part of the Mexico City Project, measurements of BC, PPAHs and many other gas- and particle-phase emissions were measured in Mexico City using a mobile laboratory during the Mexico City Metropolitan Area field campaign in April 2003 (MCMA-2003). The main goal of this research is to estimate emissions of BC and particulate PAHs (PPAHs) for Mexico Cityâ s vehicle fleet. The emissions of gas-phase pollutants such as carbon monoxide (CO), total nitrogen oxides (NOy) and volatile organic compounds (VOC) are also estimated. The mobile lab has previously been used to chase vehicles and measure their emissions, but analysis has traditionally focused on determining emission factors of individual vehicles associated with specific chasing events. The laboratory continuously samples ambient air from an inlet at the front of the van, and it is always â seeingâ exhaust plumes from the vehicles around it while driving through traffic. We have developed an algorithm that automatically identifies the exhaust plume measurement points, which are then used as the basis for calculation of emission factors. In the nearly 90 hours of on-road sampling during the field campaign, we have identified ~30,000 exhaust measurement points. The large sample size enables us to estimate fleet-average emission factors and thus the emission inventory. Motor vehicles are estimated to emit annually 1,960 tons of BC, 56.2 tons of PPAHs, 1,320,000 tons of CO, 125,000 tons of NOy and 2440 tons of VOCs. The spatial and temporal patterns of BC and PPAHs in different locations with in MCMA are also studied.Master of Science

Full textAbstract:
While the ancient city of Teotihuacan (150BC-650AD) was one the most striking experiments in urbanism in the pre-industrial world, housing a population likely exceeding 100,000 inhabitants in ca. 20 km2, it is likely its inhabitants faced significant economic, social and political challenges in sustaining such dense urban society. As part of wider palaeodietary and cultural investigations at ancient Teotihuacan, organic residue analyses were performed on a wide range of systematically sampled archaeological potsherds from three localities within the city and immediate periphery: La Ventilla (n=148), San Jose 520 (n=73) and site 15:N1E6 (n=92). The main aims of this thesis were to further investigate the relative importance of various foods and food consumption patterns over time and across different parts of the city to relate differences in food consumption to social variation. Absorbed lipid extractions performed on the 313 potsherds represented different ware types and forms, including: ollas (n=144), craters (n=83), bowls (n=24) and amphorae (n=62) corresponding to the Tlamimilolpa and Xolalpan phases (ca. AD 200-550). Due to the low lipid concentrations in potsherds from Teotihuacan, a more efficient lipid residue extraction method involving the use of acidified methanol (H2S04iMeOH 2% v/v, 70°C, 1 h) was developed and applied to the archaeological ceramics from the city. GC screening of the total lipid extracts (TLE) showed 67% of the potsherds contained detectable lipids, with an average concentration of 16 flg g-l. GC-MS of lipid extracts revealed up to ten different classes of biomarkers. The presence of high concentrations of long-chain fatty acids (C22:0 and C24:0) a series of even-chain n-alkanols (C22 to C34) and/or the presence of very low concentrations of plant stanols and sterols together with characteristic Ol3C values of C4 plants suggests the lipid residues of most of potsherds derive from maize (leaf and/or kernel) or mixtures of maize with other commodities with a higher input of maize. Although the analyses provided compelling evidence for the predominance of maize oils/waxes in pottery samples from the three localities, no differences in food consumption patterns were detectable across time and socio-economic status. In addition, the production of the fermented drink, pulque, at Teotihuacan was confirmed through the identification of pine resins (post-firing waterproofing) and bacteriohopanoid (Zymomonas mobilis biomarkers) distributions in a subset of 14 potsherds from La Ventilla, suspected typologically (amphorae) to have been used in pulque production/storage/ transportation.

A proposta de intervenção compreende-se entre a ocupação de um vazio urbano com um passado industrial caracterizador e um presente expectante, e a reutilização critica das preexistências do conjunto industrial desativado. Esta procura a sua valorização e reintegração. No terreno vazio procura-se coser os dois traçados em evidência através de uma frente de rua regular e de um núcleo interior transposto do traçado orgânico. O programa consiste num uso predominantemente habitacional sensível à progressiva mutação da estrutura familiar contemporânea complementado por um equipamento educacional infantil. Propõe-se a conversão das pré-existências do conjunto industrial desativado para espaços de trabalho em diálogo diacrónico com o seu passado laboral. A presença da água foi indutora para a materialidade que se constitui através de um embasamento em basalto nivelado pela presença de um passado do Rio Tejo.

The aim of the thesis is determination and optimization of organic acids in beers using the methods of capillary isotachophoresis (CITP) and high performance liquid chromatography with diode array detection (HPLC/UV). Beer is a complicated matrix therefore the samples need pretreatment using solid phase extraction (SPE). The diploma thesis discusses the optimization of the analytical methods (HPLC/UV and CITP) and optimization of SPE. In the theoretical part, history, characterization and technology of beer production are presented. Further, characteristics of organic acids and methods for organic acid determination are also discussed. The experimental part deals with the preparation of solutions, tested samples, calibration samples. Parameters and procedures of analytical methods (HPLC/UV and CITP) and pretreatment using the solid phase extraction are also described in the experimental part. All results are summarized and compared with the current literature in discussion and conclusion. Eleven beer samples from the retail stores were analyzed. In all samples, six organic acids (lactic, oxalic, succinic, acetic, citric, benzoic) were determined by CITP and five organic acids (lactic, oxalic, succinic, acetic, citric) by HPLC/UV were determined. Results of this study give an overview of the organic acid contents in beer samples.

Previous issue date: 2013-04-16To the extent that the expansion of cities is increasingly pushing and segregating the working class to outlying areas, devoid of services and infrastructure, the urban space is also important as a space in the class struggle, and in this direction, the this study aims to analyze the political organization of urban social movements and popular organizations existing in Natal-RN, nowadays, in their process of struggle for social rights, with emphasis on the right to the city. With this dimension, we appropriate the contributions of historical and dialectical materialism because we believe that this benchmark enables the understanding of the processes of collective organization and a critical perspective of totality, going beyond its immediate appearance. For production data conducted literature, documentary and field, through semi-structured interviews recorded with (the) mapped leaders of organizations in our survey, as well as advisory bodies to the movements studied. The results of the study allowed us to characterize the action of the political movements in urban Christmas struggle for recognition and guarantee of the right to the city and seize the advances and obstacles in the process of intervention of social movements and popular organizations existing in Natal, highlighting dilemmas and contradictions underlie the processes of organization and mobilization in the contemporary period. Thus, we conclude that the Natal territory, as in contemporary Brazil, the urban and political action movements that show the public scene and intertwine necessarily relate to historical trend that has been performing since the 1990s, when the country entered a period marked by a new bourgeois offensive

The project is solving problem with Library in Prerov and its location on the site and connection to existing infrastructure. The project can be divided into three parts - urban solutions, architectural design and technical solutions. Urban solutions The area is currently degraded by uncontrolled parking of cars and too much communication. This causes confusion functioning of transport and pedestrians weaving between cars. Vegetation is devastated. Influencing factor is the close proximity to the City Circle, whose importance will increase, if realized "shortcut" towards the main railway and bus station. The proposal aims to improve respectively. build high-quality public space. The library building is defined as a solitaire, a reaction to the complicated and urban neighborhood. Its placed on the Conner for puting there some object of interrest. Communications are in the area reduced. Towards the north west corner of the square is placed park.

Recently, industrial growth and urbanization in Taiwan area caused a variety of air pollutants, especially volatile organic compounds (VOCs) that produced from increasing of motor vehicles. Moreover, many private gas stations were installed in metropolitan. A report of Taiwan Environmental Protection Agency (EPA) was showed the increasing of VOCs concentration by increment trend based on the number of motorcycle. Commuters were exposed to higher concentration of VOCs at short period than indoor air during a long period. The objective of this study is to investigate the commuter exposed to concentrations of VOCs at six main roadsduring four time periods and also estimated the risk regarding to exposure of benzene based on exposure assessment. The sampling and analytical method was taken from method 17 certified by U.S. EPA. Strictly procedure of quality control was performed and measured concentration of VOCs in six main roads and four time periods. VOCs concentrations of indoor air both smoking and non-smoking were determined. Results indicated the eight compounds of VOC was determined as following benzene, 1-heptene, n-heptane, toluene, m,p-xylene, ethylbenzene, o-xylene and isopropylbenzene. Both of VOCs concenration were shown significant correleations except I-heptene. Commuter exposed to VOCs was found the highest concentration in Ta-Yai road. The highest concentration to toluene in Taichung city was found, following by benzene and lowest in isopropylbenzene. Time of morning and evening during commuting period had higher VOCs concentration, lowest in afternoon at p.m. 2.00-3.00. Ratios of BTEX (benzene:toluene:ethylbenzene:xylene) with 5.7:2:2.6:1 in motorcycle and with 5.5:2.1:2.6:1 in car were indicated that concentration of VOCs mostly from mobile sources. Comparison of VOCs concentration in houses between smoking and nonsmoking showed a higher concentration to office and family in smoking area. Risks of exposure to benzene in commuter were measured to be 4.92E-05 with motorcycle and 4.01E-05 with car, respectively. Risks of exposure to benzene in office and house with 3.52E-05 and 4.90E-05 in smoking area and of 2.76E-05 and 4.01E-05 in nonsmoking area were found. Average risks of exposure to benzene during commuting and in office was respectively 7.68E-05 with motorcycle and 6.780E-05 with car in Taichung city. VOCs concentration was higher than other country cities but slightly lower in Taipei city. The author suggested that the effective control strategy of air pollution in metropolitan for Taiwan EPA should greatly promoted and then reduced the risk of developing the cancer and other abnormalities due to VOCs.

abstract: There is never a better time for this study than now when Nigeria as a country is going through the worst time in power supply. In Lagos city about 12,000 tons of waste is generated daily, and is expected to increase as the city adds more population. The management of these waste has generated great concern among professionals, academia and government agencies. This study examined the regenerative management of organic waste, which accounts for about 45% of the total waste generated in Lagos. To do this, two management scenarios were developed: landfill methane to electricity and compost; and analyzed using data collected during field work and from government reports. While it is understood that landfilling waste is the least sustainable option, this study argued that it could be a viable method for developing countries.
Using U.S EPA LandGEM and the IPCC model, estimates of capturable landfill methane gas was derived for three landfills studied. Furthermore, a 35-year projection of waste and landfill methane was done for three newly proposed landfills. Assumptions were made that these new landfills will be sanitary. It was established that an average of 919,480,928m3 methane gas could be captured to generate an average of 9,687,176 MW of electricity annually. This makes it a significant source of power supply to a city that suffers from incessant power outages.
Analysis of composting organics in Lagos was also done using descriptive method. Although, it could be argued that composting is the most regenerative way of managing organics, but it has some problems associated with it. Earthcare Compost Company processes an average of 600 tons of organics on a daily basis. The fraction of waste processed is infinitesimal compared to the rate of waste generated. One major issue identified in this study as an obstacle to extensive use of this method is the marketability of compost.
The study therefore suggests that government should focus on getting the best out of the landfill option, since it is the most feasible for now and could be a major source of energy.Dissertation/Thesis

This study analyzes the spatial distribution of volatile organic compounds (VOCs) emissions in 29 districts of Taichung city from 2007 to 2011. The data were collected from officially annual reports of emissions of stationary air pollution sources. Spatial analysis, such as population distribution, emission distribution, and exposure populations, were performed by geographic information system to investigate the correlation between VOCs and cancer mortality.. The results showed that nearly 50 percent of the population is exposed to a VOCs emission level of 0 to 1,000 kg/year. Generally, the exposure populations of most of the emission levels remain stable or decreased, except that the exposure population of emission level of 3,001 to 5,000 kg/year increased approximately 2% per year. Furthermore, the analysis indicates that there is no significant correlation between cancer mortality and VOCs emission. Since long-term exposure to high VOCs emissions will not only affect human health but also increase risk of cancer. Therefore, the Environmental Protection Bureau should sufficiently collect the stationary air pollution sources characteristics and fingerprint data, and actively promote hazardous air pollutants species control strategies and other related emission control policies.

Organic food has developed in Taiwan for several years, however, the fake organic food still can be found in the market, and consumers start to lose their trust on the organic food claimed. This research intents to study the formation of consumers’ trust on organic food which includes consumers’ tendency to trust, sources of their trust and their trusting behavior. The further understanding of the consumers’ trust will be helpful to both the organic food suppliers and the policy maker, it will provide information for the organic food store to improve consumers’ trust on them, and it will also be a good reference for government in the revision of organic food laws and regulations. This research was implemented in Taichung city, and individual questionnaire survey was conducted to consumer in order to understand their trust towards organic food, the investigative period started from March 1 to March 15,2005. There are 237 effective questionnaires. This research uses descriptive statistical and regression analysis to test the research ’hypotheses of this study, and the major findings of this study are as follows: 1. It’s found, consumers who purchase organic food are mainly by females, age in 31-50 years old, education level above junior college, career in teacher or housewife, and married with monthly income between 30,000- 49,999 dollars. 2.The consumer who purchases organic food thinks convenience is the most important factor in the purchasing decision, and their monthly expenses is below 1,000 dollars, the purchasing frequency is once a week. The information regarding organic food mainly comes from the consumers’ voluntarily searching; the public education system provides the least information, and the organic food stores seldom provide organic food information to the consumer initially. 3. This research also found that the difference in demographic variable, such as 〝sex〞and 〝age〞can affect consumer's interpersonal trust, and 〝sex〞variable also affect consumer's trust on institution significantly. Consumer's cognition of their “tendency to trust〞also has significant influence on consumer's interpersonal trust、organizational trust and institutional trust, this demonstrated consumer's cognition of 〝tendency to trust〞acts as an important role in the formation of consumer trust on organic food. 4. Consumer's interpersonal trust and organizational trust are significantly influenced by the salesperson's characteristics（friendliness, reliability, professionalism） and the organization's characteristics（organizational reputation）; However, the consumer's cognition on the institutional trust were only found significantly influenced by consumer’s perception of their understanding on〝the organic food regulations〞. As a result, the organic food stores may increase the consumer's trust on the organic food by improving their 〝reputation〞, 〝staff training〞and 〝advocating the organic food regulations”. 5. Consumer's interpersonal trust and organizational trust has remarkably influence on all the consumer's trusting behavior variables. However, it’s also found that the institutional trust does not affect the consumer's〝purchase intention〞、〝recommendation to other persons〞and〝communicating organic food information to others〞, this might be because that the population is still lack of fully understanding of organic food authentication system, and therefore, in doubt. This might be the reason why consumer's institutional trust does not statistically significant affect these three trusting behavior variables.

Kaohsiung is a densely populated harbor city, in which the density of motor vehicles is also high. Since the temperature and sunlight is also relatively high in Southern Taiwan, tending to transform ambient volatile organic compounds to ozone thus causes high ozone events. This study measured the concentrations of 63 hydrocarbon (HC) species from C2 to C15 simultaneously at the Nan-Chie and Hsiung-Kong sites in Kaohsiung city during the morning (07-10), the afternoon (13-16), and the evening (18-21) periods on three successive days in winter 2004. Results show that the most abundant species of Kaohsiung’s air is toluene (43.01-60.95 μg/m3), followed by i-pentane, 1,2,4-trimethylbenzene, benzene, n-butane, propane, and acetylene, in the range 9.55-16.93 μg/m3, while the concentrations of halocarbons is 0.17-4.12 μg/m3. Alkanes (44.7-45.9%) represent the largest proportion of the total HC, followed by aromatics (35.4-36.8%), alkenes (10.5-10.9%) and halocarbons (3.6-3.9 %). The OFP (ozone formation potential) of HC species were evaluated based on the MIR (maximum incremental reactivity). Results show that aromatics (45.9-54.3%) represent the largest proportion of the OFP, followed by alkenes (17.7-37.5%), and alkanes (16.5-23.6%). The results from the factor analyses show the major sources of ambient HC in Kaohsiung city are the vehicle exhausts, industrial processes, solvent evaporations, combustion exhausts, and petrochemical processes.

There are many traffic problems caused by increased amount of vehiclesin Taipei. The government established some strategies to solve these problems. Establishing exclusive bus lanes is one of the important implement, but which may bring another suffer for people. In addition , an alternative of anti-knocking chemical-MTBE has been proved to be an animal carcinogen recently, and has raised public concern as well. The purpose of this study were to realize the concentrations and the spacial distributions of airborne volatile organic compounds (VOCs) at main roads, sidewalk bus stops, exclusive bus lane stops and gasoline stations in Taipei City, and the personal exposure levels of gasoline station workers. This study collected air samples from five main roads, four sidewalk bus stops, three exclusive bus lane stops, eight gasoline stations, and twenty-six gasoline station workers. Charcoal tubes were used to collect VOCs in air, and a GC/FID was used to analyze the concentrations of MTBE, n-hexane, benzene, toluene, ethylbenzene, and xylene. The results showed the average concentrations of VOCs were the highest at gasoline stations, and decreased in sequence of main roads, exclusive bus lane stops, and sidewalk bus stops., the concentration were 75.8, 51.6, 113.4, 305.2, 45.0, 121.1 and 66.4μg/m3 for MTBE, n-hexane, benzene, toluene, ethylbenzene, m,p-xylene for o-xylene at main roads; respectively. These were 41.3、27.6、101.2、221.5、40.0、124.8 and 50.7 μg/m3 at exclusive bus lane stops, respectively. These were 42.1、16.7、71.8、115.7、23.7、40.2 and 17.3 μg/m3 at sidewalk bus stops, respectively. Toluene was the major airborne VOCs, the concentrations were 305.2 at main roads and 166.6 μg/m3 at bus stops. The concentrations of VOCs in rush hours were higher in the afternoon than thos in the morning. The concentrations of VOCs at exclusive bus lane stops were significantly higher than that at sidewalk bus stops, and the former was several-fold than the latter. At gasoline station, the airborn concentrations of MTBE, n-hexane, benzene, toluene, ethylbenzene, m,p-xylene and o-xylene was 685.3、212.9、203.7、577.5、86.1、234.5 and 93.9 μg/m3, respectively. The personal exposure of gas station workers was far belows the PEL of Taiwan OSHA regulation. The VOCs levels were not difference between private and public gas stations. Personal exposure levels of VOCs for gasoline station workers were significantly higher than that for ambient air.

On the basis of the air monitoring statistical data, the pollutant concentration of air in the West Taiwan usually exceeds the air quality standard, especially in Kaohsiung and Pingdong area. More than 90% of residents are not satisfied about the quality of the ambient air. The total VOC emission amount of fixed source in Kaohsiung was 17449 ton in 2002. The emission mass fractions of petrolchemical industry, semiconductor manufaracturing plant, petrol station, painting mill, surface coating process and adhesive plaster factory were 64.81, 10.64, 5.30, 4.02, 0.53 and 14.71%. In petrolchemical industry, besides the waste water treatment facility, there are still some defects in other involved regulation. The using amount of organic solvent in semiconductor manufaracturing plants was so small that there is almost no space to improve. The percentrage of the petrol stations equipped with the oil gas revovery facility was high to 99.23%, but 66.5% of them was unqualified. Therefore, the fisrt step of emission reduction is to elevate the qualified rate of the oil gas revovery facility. The regulation of the surface coating process is only about the car surface coating procedure and other process should also be ruled. The regulation of painting mill and adhesive plaster factory is applied by involved instead of direct law and it should be legislated as soon as possible due to their large VOC emission amount. In the future, the emission reduction of control plans should be checked by BACT if the limitation is achieved. The enforcement of local statute and the range of regulation should be pushed to check the emission reduction from multiple points of view. The anticipated reduction is aproximate 10333 ton per year. It is a tendency to emphasize the economic benefit such as low-interest-rate loan, taxation remitting or the reward about the factory moving when administrative control is carried out. On the other hand, it will encourage the proprietor to reduce the pollutant emission by applying natural resource in the production process. The pollution control and conomical benefit should be also maintained concurrently to save cost, labor and time. The imposition of the air pollution control charge is the main source of the budget for the pollution remediation. However, the detailed implement procedure, the impaction on the business and the involved accessory measures should also be deeply investigate to assess the possibility to put it into practice.

Land use in the Chianjen District is predominantly a mixture of residential and commercial. Approximately 30.4﹪(n=63) of the listed water pollution factories in this district which is composed of petrochemical industry ,storage tanks zone and economic processing zone etc. Therefore, the groundwater has been contaminated possibly. There are some citizens using groundwater as domestic water supply source for doubting about tap water quality and pressure, even if it is contaminated. The purpose of this research is to study on contamination of VOCs in groundwater and consult some references to investigate the source of pollution. Besides, evaluating of citizens’ health effect with using groundwater by exposure assessment and insurance database analysis. Investigation of using water habits of citizens in the Chianjen District by questionnaire and telephone. Choosing 10 sampling sites according to direction (east, west, south, north, middle), 2 samples at each direction, and sampled waters 2 times (high water table and low water table). Taking advantage of published method by EPA-- NIEA W785.51B to analyse. Collecting demographics and integrating insurance database to use Conditional Logistical Regression as a tool to find out the difference between the exposure and control about diseases of interest and reference disease. Using formulas and models as tools to take exposure assessment and get parameters from ICRP to estimate CDI (Chronic Daily Intake ). After questionnaire, we have still 23.1% (n=150) of residents still using groundwater as their domestic water. There are 24 and 15 kinds of VOCs detected at high and low water table period, respectively. Two (VCM,TCE) of all exceed the drinking standard of Taiwan , another two (Tetrachloroethene, 1,1,2-Trichloroethane) exceed the U.S., and the concentrations of four are 42.1,41.7,32.1,and 31.5ug/L, respectively. Statistical analysis of insurance data, shows no difference between exposure or control about disease whether or not using groundwater. The groundwater is polluted at some sampling locations by leaking from underground storage tanks belong to gas station and leakages of wastewater or pipelines of the factory. Owing to the budget, the numbers of sampling sites were not enough to depict the real contamination of groundwater. Although, it wouldn’t increase the opportunity of cancer whether use groundwater or not , but if residents were using the sampling site 2 as their water supply source, their health should be affected extremely.

This study was to understand the current status of the organic product market in Taitung. Using questionnaires, this study surveyed consumers in Taitung City to determine whether there differences between certain demographic variables and the health behaviors, organic product cognition, and motives for purchasing organic products. Also determined were the relationships among the health behaviors, organic product cognition, and motives for purchasing organic products. Results of the study could be used to better grasp the consumers’ needs and characteristics for future reference. The result showed that consumers of organic products in Taitung City were mostly female at the age of 31 years or older, married at the middle or low income level, employed by the military or governments, and from families with patients of chronic diseases. Consumers who did not buy organic products attributed the reasons to expensive prices, inability to differentiate organic products and too much negative information about the products. However, the reasons prompted consumers to buy organic products were attributable to the name brands associating with the products and their certification logos. In terms of purchasing price and frequency, the highest number of consumers surveyed checked the category “uncertainty.” Organic agricultural products were the most purchased items among all the organic products. Stores selling organic products and the supermarkets owned and operated by various district farmers’ associations were the major sources for the purchase of organic products. As high as 70.4% of the consumers surveyed mistakenly identified GAP as a recognized logo for certified organic products. The result also revealed that the consumers purchasing organic products, which were certified by the government, showed the highest propensity in selecting products bearing MOA and TOFA logos. Significantly more females than males selected health behaviors and motives for purchasing organic products. Also significantly more married than unmarried consumers chose health behaviors and organic product cognition. Consumers of college graduates were significantly higher in number in choosing organic product cognition. More retired consumers checked health behaviors than those of housekeepers and persons involving in industrial activities. Consumers with personal monthly income above NT$60,000 showed higher interest in health behaviors than those with personal monthly income less than NT$40,000. Similarly, consumers with family monthly income above NT$110,000 showed higher preference for health behaviors and organic product cognition than those with than NT$30,000. Families with patients of chronic diseases chose health behaviors, organic product cognition and motives for purchasing organic products significantly more than those without patients of chronic diseases. There was a positive correlation among health behaviors, organic product cognition and motives for purchasing organic products.

Due to the densely populated and narrow hinterland of Taiwan, most of the sewage treatment plants are close to the residence area. When the sewage treatment plant is in operation, a foul odor is released into the air that can cause health related problems. Some hazardous air pollutants emitted by these sewage treatment plants include hydrogen sulfide, ammonia, and volatile organic compounds (VOCs) which can have a negative effect not only on health but also on the image of Taiwan. These pollutants will be directly affected by the air to the health of the human body, coupled with the current face of Taiwan''s air quality deteriorating, and the infrastructure of volatile organic matter emissions of the situation, this study to explore. In this study, two sewage treatment plants in Taipei were surveyed on the perimeter and the air quality of the plant, And the concentration and composition of volatile organic compounds in the two municipal wastewater treatment plants were measured by means of a reading instrument and a stainless steel sampling tube. And selected a site of the factory''s primary settling tank for a long time to monitor the changes in pollutants. The experimental results are the next.The air quality, the concentration and composition of the pollutants in these two municipal wastewater treatment plants were measured using a passive flow controller. The concentration of pollutants in the primary settling tank of these factories were compared and monitored for four seasons.This study was also monitored for four seasons for 7-days and days with highest concentration of pollutants. During the long-term monitoring, the concentration of pollutants in the spring is the highest among four seasons, the maximum having 50.9 ppmv. Furthermore, the concentration of pollutants is the highest at night with aromatic hydrocarbons having the highest composition among other pollutants with toluene having the highest concentration. The maximum amount of emissions in the compound resulted up to a total discharge of 84%. The sewage treatment plant emissions OFP value of toluene during summer was calculated with a maximum point reaching up to 225.53.

Given the frequent events of food safety in recent years, nationals have increasing demands for organic products, which has led to the expansion of organic farming or continuous appearances of organic chain stores and farmers’ markets. This shows that nowadays people have paid more attention to organic agriculture than before. As for schools, some cities or counties have promoted organic lunch meals in schools, and all cities and counties have gradually developed “food and agriculture education” in order to help children become familiar with land and understand the process of food ingredients from places of origin to tables. Organic agriculture emphasizes “health”, “ecology”, “fairness”, and “care” and provides one or many feasible solutions to the current issues of global environment, such as global warming, or for agriculture, rural areas, or farmers. In elementary schools and junior high schools, teachers are the drivers of fundamental education as well as important consumers of organic agriculture products. Related researches have also indicated that education can improve health and diet as well as understanding of environmental conservation, which brings a positive influence on improvement in agricultural awareness. If teachers are willing to promote the concept of organic agriculture and help children cultivate an organic concept, organic agriculture will be developed and expanded in the future. The study aimed to discuss the elementary school and junior high school teachers’ degree of “perception of organic agriculture”, analyze the “behavior intention of organic agriculture products’ consumption” through theory of planned behavior, and explore the elementary school and junior high school teachers’ “education willingness of organic agriculture” and factors of obstruction, and whether “perception of organic products” and “behavior intention of organic agriculture products’ consumption” have significant influence on the “implementation of education willingness of organic agriculture”. The study targeted elementary school and junior high school teachers in Chiayi City. The study adopted the questionnaire survey and carried out background data analysis, reliability analysis, descriptive analysis, ANOVA and regression through statistic software. The result showed that the elementary school and junior high school teachers agreed on the “perception of organic agriculture” most in the aspect of “environmental conservation”. The “perceived behavioral control” had the greatest influence on the “behavior intention of organic agriculture products’ consumption”. The elementary school and junior high school teachers generally considered that “the understanding of organic agriculture products will affect consumer behaviors”. In the aspect of “education willingness of organic agriculture”, teachers agreed on organic education in terms of “willingness”; however, the willingness to “determine” to implement organic education was lower. Regarding the factors of obstruction, “less understanding of organic agriculture and organic agriculture products” accounted for the highest percentage. In the category of “females” and “frequent consumers of organic agriculture products”, the elementary school and junior high school teachers had higher perception of organic agriculture. Behavior intention of organic agriculture products’ consumption affected the elementary school teachers more than the junior high school teachers; in the aspect of “behavior intention of organic agriculture products’ consumption”, married teachers were influenced by “subject norm” and “perceived behavioral control” more than single teachers. The elementary school teachers had higher education willingness of organic agriculture than the junior high school teachers; teachers as frequent consumers of organic agriculture products had higher education willingness of organic agriculture. The elementary school and junior high school teachers’ “perception of organic agriculture” and “behavior intention of organic agriculture products’ consumption” had a significantly positive influence on “education willingness of organic agriculture”. In the “perception of organic agriculture”, the perception of “fair care” was higher than other perceptions. In addition, the greater influence of “attitude” on “behavior intention of organic agriculture products’ consumption”, the higher education willingness of organic agriculture. The study suggested that “organic agriculture” related training should be arranged for teachers to participate in and improve their perception of organic agriculture; further, teachers could integrate “organic agriculture” and “food and agriculture education” with environmental education courses in schools; teachers could also teach organic agriculture through clubs or summer and winter camps; “organic agriculture” and “food and agriculture education” were easier to be implemented in elementary schools than in junior high schools.

The reuse of waste is the policy of government. The Taiwan Environmental protection Administration (TEPA) formulated the “Waste Disposal Plan” in 2003 to promote “zero waste” and to launch the policy of “waste minimization and resource recovery” in which green manufacturing, green consumption, source minimization, resource recovery, and reuse were promoted. These measures effectively recycled wastes and achieved zero waste gradually. More than 70 tons of organic wastes from fruit and vegetable market are produced every day in Taiwan. Among these, larger 63 markets produce 40 to 50 tons of fruit and vegetable wastes. Currently, the organic wastes from fruit and vegetable markets are carried by contract companies which send these wastes to incinerator plants. But it depends on the contract companies whether the organic wastes are classified or not. This research mainly discussed the measures of how to effectively recycle the organic wastes from fruit and vegetable markets in Taiwan. First, literatures including the classification of organic wastes on economy, technology, and present law were collected to design the first stage questionare. The first stage questionares were filled up and screened by the experts in accordance with Likert test. Consequently, the second stage questionare was designed based on the results from the first stage survey. The analytical hierarchy process (AHP) was employed to analyze the weights of second stage questionares. The results indicated that the four major indicators for effectively recycling the organic wastes from fruit and vegetable markets were in the order: the aspect of law and system, the aspect of operation and assistance, the aspect of technology and the aspect of society. Their weights were 0.366, 0.314, 0.187 and 0.134, respectively. These four factors were the key factors that affected the performance for recycling the organic wastes from fruit and vegetable markets. It will be easy to recycle the organic wastes from fruit and vegetable markets if regarding these four factors.

In recent years, people gradually increased environmental awareness, coupled with domestic food safety issues, the rise of the organic food market growing, but consumer understanding of organic food, understanding and acceptance can not be directly observed, in addition, the price of organic food is higher than ordinary food, and organic food pathway than factors such as general food are all in this one narrow path variables infertility research explored. Therefore, this study by Ajzen (1985) proposed "theory of planned behavior (Theory of Planned Behavior)" for factors affecting Taiwan's consumers buy organic food, and give suggestions and solutions for the statistical results, prompting the organic food the development of the industry, and thus to protect the environment and people's health. Objective of the following three points: 1 identify factors that influence consumer buying organic food and the impact of the relationship. 2. To investigate the effect of demographic variables on consumers buy organic food behavior. 3. The proposed conclusions and recommendations for the organic food industry reference. This study through questionnaires (416 valid questionnaires were collected, the recovery rate of 91.8%). Research results showed that: (1) the social environment will affect the consumers to engage in certain behaviors, attitudes and perceptions, when consumer demand for food safety, you might consider buying organic food is good for the environment and peace of mind, and only the government development of relevant standards and testing system in order to promote and improve the market for organic products. (2)Corporate propaganda "health" of the concept, but also the real implementation of the "health" of protection in order to obtain the trust of consumers, improve willingness to buy organic food. And in today's society more than the pursuit of economic efficiency, and therefore may not be at high prices to buy organic products, how enterprises to maintain a good balance between cost and profit, but also a need to pay attention to the subject.

In this study, 76 atmospheric aerosol samples were collected at the National Taiwan Ocean University, the Keelung City, from January 2013 to January 2014. The concentrations of different nitrogen species, including water-soluble total nitrogen (WSTN), ammonia, nitrite, and nitrate, were analyzed. The sum of ammonia, nitrite and nitrate are defined as water-soluble inorganic nitrogen (WSIN). Water-soluble organic nitrogen concentration (WSON) was derived from the concentration difference between WSTN and WSIN. The concentrations of major ions, such as Na+, K+, Mg2+, Ca2+, Cl-, and SO42-, in the water-soluble phase were also analyzed. Three-day back trajectories of air masses arriving daily at the sampling site were calculated to determine the potential aerosol source regions. The purpose of the present work is to distinguish the atmospheric aerosol nitrogen sources collected at the sampling site. The analyzed results indicate that the analyzed concentrations clearly showed seasonal variation, reflecting different sources and weather condition. The maximum concentrations of the analyzed parameters generally appeared in the winter month when the northeast monsoon occurs. The minimum WSIN concentration was found in September because the typhoon occurred. Overall, it is found that atmospheric aerosol collected from the fall and winter seasons was from the continental source. The local and oceanic sources were dominant in the summer season.

With enhanced standard of living and knowledge level of citizens, consumers’ demands for foods have shifted to the healthiness and safety of agricultural products. Organic agriculture is an industry focusing on production, life, and ecological characteristics, as well as an environmentally friendly farming method. The current health-oriented consuming trend emphasizes high-quality and safe organic agricultural products, which has attracted increasing attention. However, it is very difficult to differentiate the organic and non-organic agricultural products from their appearances. Moreover, the organic agricultural products involve visible and invisible risks, such as the concerns over pesticide residues and fake organic foods, which may trigger the consumers’ awareness on their own risks, and potentially affect their purchase intention of organic agricultural products. The main purpose of this study is to investigate the relationship among consumers’ health involvement, perceived risk, and consumers’ purchase intention for organic agricultural products, as well as to understand the influence of demographic backgrounds on health involvement, perceived risk, and consumers’ purchase intention. This study conducted a questionnaire survey on consumers in Hsinchu City, and 400 valid samples were collected. The data were analyzed using descriptive statistics, independent sample t test, One-way ANOVA, Pearson product-moment correlation, and regression analysis. The research results showed that: (1)difference in background variables of consumers has a significant effect on health involvement, perceived risk, and consumers’ purchase intention of organic agricultural products; (2)consumers’ health involvement has a positive effect on their purchase intention of organic agricultural products; (3)consumers’ perceived risk has a negative effect on consumers’ purchase intention of organic agricultural products; (4)consumers’ health involvement is negatively correlated with risk perception. Based on the results, this study proposed relevant suggestions as reference for marketing and operation of organic agricultural products.

In recent decades, the economy in Taiwan grows soon, and the wealth also increases. In this situation, the questions about food safety, nutrition and health comes after this situation. Therefore, the demands of consumers turn into the demands of quality from quantity. Besides, people also more and more concern the health. In other words, the consuming way turns into the healthy, safe and natural way. Thus, the organic agriculture develops, and the more and more organic stores set up. The organic food is titled with nutrition and health so that consumers think of the food nutrient and healthy. However before this issue is discussed by science, we can not sure that the organic food is more nutrient than general food. Therefore, this research will show that consumers do not have enough knowledge about organic agriculture. In 1983, Carl R Rogers shows that knowledge can affect behavior and the attitude. Therefore, it is deserved to discuss that whether the knowledge of consumers towards nutrition and health will affect the purchasing behavior. This study will focus on the consumers of organic vegetables and fruit in Taichung city, and the location will include the traditional market, supermarket and organic store. The questionnaire can be divided into five parts: the knowledge of health, the attitude of health, the eating habits, the situation that the consumers purchase the organic food and demographics. This research will show that there is no any connect between the knowledge of health and the consuming. The attitude of the consumers in organic store is better than the attitude of the consumers in traditional markets. The eating habits of the comsumers in organic store are the most positive. The worse eating habits of the consumers are those in traditional market. Besides, the eating habits of the group of high knowledge are the most positive, and the eating habits of the group of middle knowledge are in between. The worse attitude of health is the group of low knowledge. The eating habit of the group of the high knowledge is better that the group of the low knowledge. They often purchase organic vegetables in supermarket and organic store. The main source of information is from the message of promotion and the commendation of friends. The purchasing time is uncertain. The sum of money is under two hundred and fifty dollars. The reason of purchasing is health, nutrition and freshness. Besides, they think that the price is too high and the categories are not complete.

In recent years, people have better living standard and becoming more and more health conscious. Especially there is a lot of negative news about food safety in recent months. Because of this , there is no doubt that people are paying more and more attention to their health and nutrition. They care about the issue of food safety and want the foods which they eat are not only delicious but also balanced, nutrient ,and safe. Thus, they can keep in shape and long-lived .In view of above mentioned reasons, organic food demand is increased rapidly. Organic vegetables and fruits is the food product which closest to people&;#39;s life. In this study, we analyze people&;#39;s consumption behavior and behavior intention in organic vegetables and fruits. Applying the theory of planned behavior , our research uses the questionnaire survey procedure to get the data. Information available to SPSS statistical package for statistical analysis. Studies have shown that attitude, subjective norm , perceived behavioral control, and trust have positive effects on their behavior intention. More perceived risk people feel, then they have more negative effects on their behavior intention. The results will provide government and organic food dealer a great reference, and recommended that the government should be regular testing of all organic fruits and vegetables, strict checks to ensure quality. Therefore, people may increasing the purchase intention to buy organic vegetables and fruits.

This study examines whether and how students were affected in their cognitions, attitudes, and behaviors toward eating organic vegetables by the food and farming education programs (F&A Programs). It was found that how practicable the teaching methods and contents of the F&A Programs are and how they are implemented influence the students’ willingness in eating organic vegetables and help to shape the students’ lifelong, sustainable, healthy, and organic dietary behaviors. It was also found that Good course materials and planning play a significant role in making the F&A Programs successful. This study used cross-sectional studies on the sixth grade students in an elementary school in New Taipei City, Taiwan. Among the 200 questionnaires distributed, 180 returned, 131 of which were valid, with a 73% completion rate. After statistical analysis and data processing based on Pearson product-moment correlation, descriptive statistical analysis, reliability analysis, factor analysis, and multiple regression analysis, the survey data showed that the more positive the cognitions of organic vegetables are, the more positive the attitudes toward organic vegetables would be, and that the more positive the attitudes toward organic vegetables are, the more positive the organic dietary behavior would be. The regression analysis indicated that the sixth graders’ cognitions toward organic vegetables significantly affect and positively correlated with the students’ willingness, and that their attitudes towards organic vegetables were also affected and positively correlate with their willingness. Therefore, the study showed that students’ cognitions and attitudes were effective in predicting their willingness, and that the more positive the students’ cognitions toward organic vegetables were, the higher their willingness of consuming organic vegetables would be.

In this study,117 rain water samples were collected from a coastal city (Keelung) and a remote island (Pengjiayu) located on the south of East China Sea (ECS) during the period from January to December 2017. The rainfall samples were analyzed for total dissolved nitrogen (TDN) which includes dissolved inorganic nitrogen (DIN) and dissolved organic nitrogen (DON), dissolved inorganic phosphorus (DIP) and major ions. To understand the influence level of rainfall types, we have classified the types into continuous and special (plum rain and typhoon) rainfall types. The mean concentrations of DIN at Keelung and Pengjiayu were 90.5 ± 167 μM and 53.9 ± 41.9 μM, respectively, which accounted for 35 ± 12% and 55 ± 15% of the TDN, respectively. The mean concentrations of DON at Keelung and Pengjiayu were 95.3 ± 187 μM and 48.6 ± 46.3 μM, respectively, which accounted for 38 ± 13% and 66 ± 9% of the TDN, respectively. Regarding the flux, the DIN and DON were 277 ± 28.6 mmol m-2 yr-1 and 129 ± 16.9 mmol m-2 yr-1 in Keelung, respectively; and were 32.2 ± 2.7 mmol m-2 yr-1 and 53.2 ± 4.6 mmol m-2 yr-1 in Pengjiyu, respectively. The concentrations of DIN and DON were 76.7% and 23.3% of TDN, respectively, at Keelung during typhone rainfall period. During the typhone rainfall period, the concentrations of DIN and DON were 18.5% and 81.5% of TDN at Pengjiyu, respectively. The results show that DIN at Keelung and DON in Pengjiyu play a key role on the nitrogen cycle in the atmosphere.
