This study was conducted to solve the problem of public grievance owing to odor of a pig farm. Odor emissions from pig production systems mainly originate from liquid manure storage and solid manure fermentation. The low-cost odor abatement system (OAS) for application at liquid manure storage tank and solid manure fermentation facilities was developed in this study. The OAS adapted odor removing principles of a biofilter and biotrickling filter. The OAS is very simplified in structure. The appearance of the OAS had a form of cylindrical or cubical shape. The system performance was monitored for about one year after stabilization. A 7 seconds empty bed contact time for the OAS was adapted to achieve the odor reduction levels. The commercial type of OAS was constructed with media comprised of wood chips. Moisture content always remained above 50% wet basis. Average ammonia removal efficiency for the developed design was 89% at the liquid manure storage tank. Also, the removal efficiency at a solid manure fermentation facility was 86% on ammonia.

Recent public concern about air pollution caused by swine production facilities has forced to develop the methods to reduce and control the swine odors. Swine odors were affected the life of pig farm neighborhoods, swine productivity, pig health, diseases, and human right, safety, sanity as negatively. The first approaches of control of swine odors are the change or improve of the classical management systems, which are manure treatment method, manure storage facility, phase feeding, sex-divided feeding, feeder type, liquid-slurry feeding, environment control of swine building and dust control of indoor swine facility. The methods to control odor emission from manure have to include the diet modification as nutritional basis. In recent, research emphasis has focused on manipulating the swine diet to increase the nutrient utilization of the diet to reduce excretion products and reduction of odors. There are lots of feed additives and pit additives introduced as practical basis for reducing odor emissions. The ozone treatment method is candidate as the good system for reducing swine odor. But this system is still too expensive to practice in present.

Objective: The aim of this study is to identify foot shapes of Korean male farmers by classifying their foot types using 3D scan data and analyzing the characteristics of each type. Background: The increasing demands for anthropometric information for the design of machinery and personal protective equipment to prevent occupational injuries has necessitated an understanding of the anthropometric differences to be found among occupations. Static stooped posture and squatting posture are so common in Korean farmers that anthropometric deformation in foot especially seems to occur easily. Method: 366 Korean male farmers volunteered for this study from 16 different farming villages nationwide from 2009 to 2011. Subjects were categorized into 4 age groups from 40s to 70s. Their right feet were measured by using 3D foot scanner, the anthropometric dimensions were composed of 40 items. Results: The 8 major factors affecting the foot shapes were extracted. From these factors the foot shape of Korean male farmers was classified into 3 Foot types. Foot type 1 showed severe deformation in toe 1, type 2 had a narrow shape and type 3 had a wider width for its length. Conclusion: There were some differences in foot shape and types between farmers and the public. The most characteristic foot type in Korean male farmers was type 3. Application: The results of identifying foot shapes of Korean male farmers might provide the useful information for designing ergonomic farm work shoes.

The principal aim of this field study was to determine the concentrations and emissions of gaseous contaminants such as ammonia and hydrogen sulfide in the different types of pig buildings in Korea and allow objective comparison between Korea and the other countries in terms of pig housing types. This field study was performed from May to June and from September to October in 2002. Pig buildings investigated in this research were selected in terms of three criteria; manure removal system, ventilation mode and growth stage of pig. Measurements of concentration and emission of ammonia and hydrogen sulfide in the pig buildings were done in 5 housing types and the visited farms were 15 sites per each housing type. Concentrations of ammonia and hydrogen sulfide were measured at three locations of the central alley in the pig building and emission rates of them were estimated by multiplying the average concentration($mg/m^3$) measured near the air outlet by the mean ventilation rate($m^3/h$) and expressed either per pig of liveweight 75kg(mg/h/pig) or per area($mg/h/m^2$). Concentrations of ammonia and hydrogen sulfide in the pig buildings were averaged to 7.5 ppm and 286.5 ppb and ranged from 0.8 to 21.4 ppm and from 45.8 to 1,235 ppb, respectively. The highest concentrations of ammonia and hydrogen sulfide were found in the mechanically ventilated buildings with slats; 12.1 ppm and 612.8 ppb, while the lowest concentrations of ammonia and hydrogen sulfide were found in the pig buildings with deep-litter bed system(2.2 ppm) and the naturally ventilated pig buildings with manure removal system by scraper(115.2 ppb), respectively(p<0.05). All the pig buildings were investigated not to exceed the threshold limit values(TLVs) of ammonia(25 ppm) and hydrogen sulfide(10 ppm). The mean emissions of ammonia and hydrogen sulfide per pig(75kg in terms of liveweight) and area($m^2$) from pig buildings were 250.2 mg/h/pig and 37.8 mg/h/pig and $336.3mg/h/m^2$ and $50.9mg/h/m^2$, respectively. The pig buildings with deep-litter bed system showed the lowest emissions of ammonia and hydrogen sulfide(p<0.05). However, the emissions of ammonia and hydrogen sulfide from the other pig buildings were not significantly different(p>0.05). Concentrations and emissions of ammonia and hydrogen sulfide were relatively higher in the pig buildings managed with deep-pit manure system with slats and mechanical ventilation mode than the different pig housing types. In order to prevent pig farm workers from adverse health effect caused by exposure to ammonia and hydrogen sulfide in pig buildings, they should wear the respirators during shift and be educated sustainably for the guideline related to occupational safety.

Women are unlikely to receive an equal education, compared to men, in rural Korean society despite the equality in labor sharing. To address this issue this research aims to (a) analyze the educational needs for farming skills and daily life management in rural communities, and (b) develop a model for educational programs reflecting regional characteristics for the female farmers in order to make them experts in agriculture. A structured questionnaire was administered, using a group interview method, to 366 female farmers from the Jeonnam, Chungbuk, and Gyeonggi provinces with help of agricultural agents. The major components of the questionnaire dealt with individual peculiarities, educational environment, and curriculum and training subjects wanted by the female farmers. Educational program content was classified as daily life management, scientific farming and agricultural management skills to create systematic and effective programs. It was found that the critical factors for developing educational programs for the female farmers are as follows: a. It is necessary to develop a program combining daily life management skills and farming skills to make the female farmers experts in agriculture. b. Statistically significant differences were found in the female farmers' educational program participation and needs based educational level, age, educational expenditure, farm type, farming experience, and farm scale. Therefore, it is necessary to develop a program considering the fore-mentioned socioeconomic status and farming characteristics. c. It is important to establish an educational system for the female farmer to improve their quality of life as a minority group in Korean society. In addition, it is also necessary to develop public relations program to ensure that female farmers recognize the importance and necessity of the education.

In the traditional subsistence farming era in Korea, most of small farmer's housing plots in the rural villages had their boundary barriers of which materials being the natural ones provided from nearby places. However, during the rapid industrialization period from 1960s, a traditional type of boundary barriers in the rural villages had been replaced mostly by low-cost factory-made ones, which means absolute loss of their amenity values as a linear part of villagescape. In spite of many study efforts on boundary barriers of traditional rural houses, detailed historical dating on them after 1960s have not tried up to now, which provoked to try this study. Through the direct and in-depth interviews to rural villagers sampled from 21 case villages, it was found that original boundary barriers structure in most of farm houses was made of natural materials like stone, soil, trees and bamboo, but, replaced by cement block structures mostly during Saemaeul Project period. However, although being relatively minority, traditional ones have been preserved up to now mainly in remote mountainous and seashore villages, but was in very low condition. In the overall view, for more than half a century, boundary barriers of farm houses had been left without public or private improvement efforts. In order to enhance their amenity values, more research works should be carried out on positive reassessment of the traditional ones harmonized with multifunctionalities for modern village life.

Background: Colistin and carbapenem-resistant bacteria have emerged and become a serious public health concern, but their epidemiological data is still limited. Objectives: This study examined colistin and carbapenem resistance in Escherichia coli and Salmonella from pigs, pig carcasses, and pork in Thailand, Lao PDR, and Cambodia border provinces. Methods: The phenotypic and genotypic resistance to colistin and meropenem was determined in E. coli and Salmonella obtained from pigs, pig carcasses, and pork (n = 1,619). A conjugative experiment was performed in all isolates carrying the mcr gene (s) (n = 68). The plasmid replicon type was determined in the isolates carrying a conjugative plasmid with mcr by PCR-based replicon typing (n = 7). The genetic relatedness of mcr-positive Salmonella (n = 11) was investigated by multi-locus sequence typing. Results: Colistin resistance was more common in E. coli (8%) than Salmonella (1%). The highest resistance rate was found in E. coli (17.8%) and Salmonella (1.7%) from Cambodia. Colistin-resistance genes, mcr-1, mcr-3, and mcr-5, were identified, of which mcr-1 and mcr-3 were predominant in E. coli (5.8%) and Salmonella (1.7%), respectively. The mcr-5 gene was observed in E. coli from pork in Cambodia. Two colistin-susceptible pig isolates from Thailand carried both mcr-1 and mcr-3. Seven E. coli and Salmonella isolates contained mcr-1 or mcr-3 associated with the IncF and IncI plasmids. The mcr-positive Salmonella from Thailand and Cambodia were categorized into two clusters with 94%-97% similarity. None of these clusters was meropenem resistant. Conclusions: Colistin-resistant E. coli and Salmonella were distributed in pigs, pig carcasses, and pork in the border areas. Undivided-One Health collaboration is needed to address the issue.

도시 내 유휴지 및 하천, 도로변과 같은 공공시설부지는 오랫동안 도시민에게 도시농업 공간(텃밭)을 제공해 왔다. 그러나 유휴지와 공공시설부지에서 이루어지는 대부분의 경작은 불법이어서 텃밭 이용자와 토지소유자 그리고 공공시설 관리자간의 갈등을 유발하고, 도시경관의 질 저하, 환경오염, 공공시설물 훼손 등의 문제를 야기하고 있는 실정이다. 따라서 본 연구는 도시 내 공공시설부지 등에서 무단으로 경작되는 도시농업을 양성화할 수 있는 방안 제시를 목적으로 도시지역에 다양한 형태로 산재한 텃밭의 분포 및 이용 실태를 조사 분석하였다. 조사는 대구광역시 시지지역을 사례지로 선정하여 현장 조사, 텃밭 이용자 및 주말농장 운영기관 담당자와의 면담을 통해 이루어졌다. 연구 결과, 도시텃밭은 접근이 쉬운 주택가 인근의 개발이 제한된 녹지지역에 주로 분포했으며, 주거지에 인접할수록 텃밭의 분포수가 증가하는 것으로 나타났다. 토지이용 유형별로는 농경지에 분포하는 텃밭의 비율이 월등히 높았으나, 도로, 하천 등 공공시설부지에 분포하는 비율도 농경지의 3분의 1을 상회하였다. 텃밭을 경작하는 사람들 중 개인 소유 토지를 무임 경작하는 사람들의 비율이 가장 높았고, 국 공유지 무단경작 비율이 다음으로 높았다. 도시 내 유휴지와 하천, 도로, 철도 등 공공시설이 위치하는 국 공유지를 텃밭으로 무임, 무단 경작하는 사람들 대부분은 노인으로 나타나, 노인 여가 공간으로서의 도시텃밭의 잠재력을 확인할 수 있었다. 본 연구는 조사대상지가 특정 지역에 국한된 점, 텃밭의 규모를 실측하지 못한 점 등의 한계가 있으나, 도시텃밭의 분포 및 이용 특성을 파악하여 불법으로 경작되는 도시농업의 양성화 및 제도적 수용 필요성을 제기했다는 데, 그 의의가 있다고 생각된다.

Lowered immune function in the senile dementia patients may be related to the abnormal metabolism of amyloid precursor protein(APP). To investigate the passibility of an abnormal metabolism of APP in lymphocytes and the possible role of APP in the activation of lymphocytes in senile dementia patients, immunohistochemical study of rat spleen and fluorescence activated cell sorter analysis(FACS) of human lymphocytes with the specific antigen far each lymphocyte and double fluorescent marker with antibody to APP were performed. After stimulating lymphocyte with phytohemagglutinin(PHA), APP mRNA and protein were extracted and quantitfied and the influence of ${\beta}$-amyloid protein($A{\beta}$) specific antibody on lymphocyte division was investigated. In spleen, the majority of cells showing $A{\beta}$ immunoreactivity was found in the T-sell dependent zone. FACS indicated that around 90% $CD_4(+)$ T-cells and 60% of $CD_8(+)$ T-sell were immunoreactive to $A{\beta}$ specific antibody(mAb 4G8). Northern blot analysis shows that lymphocyte APP mRNA was gradually increased to reach a maximum at 3 days after activation with lectin mitogen PHA. However, the $A{\beta}$ immunoreactivity an cell surface remained constant during stimulation with PHA, indicating that the release of APP(secreted farm of APP) might be increased. A very large increase in soluble APP secretion was observed in T-lymphocyte upon activation, but only law levels in the resting stale. Immunoblot was carried out an the protein obtained from cell lysate after stimulating lymphocyte by applying PHA to the cultured lymphocyte, and the result was that $A{\beta}$ band of immature farm under 116 KDa marker decreased as the duration of culture was increased after PHA stimulation. The monoclonal $A{\beta}$ specific(4G8) and polyclonal APP antibodies did not inhibit the [$^3H$]-thymidine uptake of mitogen-treated lymphocytes significantly, suggesting that mitogenesis can not be inhibited by specific $A{\beta}$ and polyclonal APP antibody. These results suggest that APP is expressed in T-cell and might be closely associated with the function of T-cells.
