This paper is a part of “The Study of The Traditional Korean Ethnic Farmhousing in Yanbian. China. The purpose of this study is to investigate the activities of the chung-ji-kan(the combined kitchen and major ondol living room). of the traditional farmhouse. It is based on a survey of 124 households in the farm villages of Lungching, China. Survey research methods included a field study in Dallajae. A questionnaire was used to conduct this study. The major findings are: 1) the average family is 3.25 persons and the nuclear family type is prevalent; ) the building plan of the farmhouse is the Ham-Kyoung-Do ‘double file’ dwelling type, the average 5.2kan(51.1$m^2$) house; ) the chung-ji-kan floor changed from straw matting or seomyu-pan(a kind of veneer board) to a vinyl flooring; 4) the chung-ji-kan ondol is the important center of activities for the farm family; thus the sitting life style of Korean ondol culture continues in Yanbian, China.

This study aimed to analyze factors of importance and performance picked by customers of Bibijeong, a farm restaurant operated by the local community of Wanju-gun. Major points include: Recognition paths mostly were word of mouth and mass media, types of visit were in the company of friends, family members or work colleagues, and purposes of visit included consumption of meal and identifying features of the restaurant. Secondly, factor analysis showed that level of facility, atmosphere/cleanness, diversity of menu, employees, ingredients and network. The Cronbach Alpha coefficient was +0.6. Thirdly, average of importance of factors was 3.861 while average performance was 3.429. IPA analysis showed that employee(communication, customer contact) in the first quadrant proved the need for fast improvement through training. Atmosphere/cleanness (interior atmosphere, table clean, kitchen cleanliness, clean dishes, interion design) and employee(proficiency, menu recognition), foodstuff(freshness, origin, safety) in the second quadrant showed that the marketing strategy of improvement as well as maintaining current status is needed, including regular training and hygiene inspection. The third quadrant contains facilities(disability, baby, fire protection) and food menu(food packing, various menu, creative menu, menu description), network(village economic links), which showed the need for gradual improvement. The forth quadrant contains network(sights's near contains. The results so far can be summed into the statement that overcoming the basic functionality of providing meals and linking the restaurant with local attractions and local economy would be need, as well as building up the image of unique farm restaurant with local features, so that Bibijeong can serve as the centerpiece of community and foundation of exchange with other areas.

환경오염, 자연파괴와 자연순환원리에 의한 가축사육이 되지 않는 원인에 따른 광우병, 구제역 발생으로 현대축산에 대한 비판 이 제기되고 있다. 동물약품의 발달에도 불구하고 위험한 전염병은 사라지지 않고 있고 방제가 어려워지고 있다 독일에서는 20여년 전부터 이와 같은 현대축산의 문제점을 해소하기 위하여 환경과 조화를 이루는 유기축산이 연구되고 있으며 정부에서도 기업농 형태의 농장체계를 소규모 유기농 체제로 개편하고 있는 실정이다. 독일의 경우 1950년부터 1990년까지 산유량은 152% 증가한데 비하여 번식장애는 233%, 질병 발생은 200-300% 증가한 것으로 보고되었다. 이러한 원인은 사육환경의 불량, 부적절한 사료공급, 가축 병 발생증가에 원인이 있는 것으로 지적되고 있다. 유기축산에 의한 젖소사육의 중요한 기준은 지역 및 농장에서의 물질순환 구조로 자가사료 생산에 의한 토양-식물-가축의 통합된 순환농법을 이루는 것이다. 따라서 우리나라 축산물의 품질향상과 질병방지와 지속적인 저투입 축산을 위한 한국형 유기축산에 의한 젖소사육의 모델 설정이 요구된다 또한 국제적인 유기식품 규격인 Codex 규정과 부합하는 우리나라의 유기축산 모델설정이 필요하다

본 연구는 효소복합체 처리가 양돈분뇨의 액비화 과정의 악취제어 가능성을 조사하기 위하여 액비저장 탱크에 4주간 저장하면서 효소복합체 처리, 폭기 처리, 효소와 폭기 동시 처리 및 대조구로 나누어 비교하였다. 또한 효소복합체를 돈사에 살포하여 돈사내 공기의 질과 양돈장 부지경계선에서의 복합악취농도를 조사하였는데, 그 결과를 요약하면 다음과 같다. 효소복합체와 폭기 처리는 양돈분뇨의 액비화 과정의 암모니아와 황화수소 농도에 영향을 미치는 것으로 조사되었으며, 암모니아와 황화수소 농도는 4주간의 액비화 과정 동안 지속적으로 감소되었다. 효소복합체의 일정 수준 처리는 양돈분뇨 액비화 과정의 악취저감을 위한 효율적인 수단이 될 수 있을 것으로 판단된다. 효소복합체와 폭기 처리는 양돈분뇨의 액비화 과정의 총질소, 총인 및 암모니아성 질소 농도에 영향을 미치는 것으로 조사되었으며, 효소복합체 처리는 양돈분뇨 액비의 품질 유지와 악취저감을 위한 하나의 기술적 대안으로 충분한 것으로 보인다. 효소복합체 살포는 돈사내 공기의 질을 개선하고 양돈장의 부지경계선에서의 복합악취 저감에도 효과적으로 작용하는 것으로 나타났다. 이상의 결과를 요약하면, 효소복합체 처리는 양돈분뇨 액비화 과정의 악취제어와 고품질 액비제조 가능성이 인정되며, 돈사 내부 및 양돈장 환경개선과 악취저감 효과가 있는 것으로 판단된다.

Objectives: This study aims to assess the concentrations of ammonia and hydrogen sulfide according to task unit area at swine farms. Methods: A total of six swine farms were selected for this study. Ammonia and hydrogen sulfide were monitored using a real-time multi-gas monitor which could sample the gases simultaneously. The sampling was done in the pig building, manure storage facility and composting facility of each farm. Results: The concentration of ammonia in the pig buildings(GM 22.6 ppm, GSD 2.3) was significantly higher(p<0.0001) than in the manure storage facilities(GM 10.4 ppm, GSD 2.7) and composting facilities(GM 8.6 ppm, GSD 2.8). The concentration of hydrogen sulfide in the manure storage facilities(GM 9.8 ppm, GSD 3.2) was higher(p<0.0001) than in the pig buildings(GM 2.3 ppm, GSD 2.3) and composting facilities(GM 1.9 ppm, GSD 2.5). In particular, the levels of hydrogen sulfide in the confined manure storage facilities were higher than those in open-type facilities and the peak concentration(98 ppm) in the confined facilities was approximate to 100 ppm, at the value of Immediately Dangerous to Life or Health(IDLH). Conclusions: Suffocation accidents caused by hazardous gases at a swine farm have occurred annually. Real-time monitoring of the hazards should be done in order to protect farm workers and livestock from the sudden accidents.

Objectives: The principal aim of this study was to compare the concentrations of gaseous pollutants emitted in enclosed pig buildings between different rates of general ventilation and determine the variations in the patterns of gaseous pollutants as affected by ventilation rate. Materials and Methods: The experiment was performed in the growing/finishing room($20.0m{\times}12.0m{\times}3.0m$) of a pig confinement building located on the experimental farm of Seoul National University. The conditions of the general ventilation rate for three treatments were 30%($4.12m^3s^{-1}$), 50%($6.87m^3s^{-1}$) and 70%($9.61m^3s^{-1}$). The data presented in the study were collected overa total of 45 days, 15 days for each of the three treatments from March to May 2011. A total of six air samplings were taken at 1.5m above the floor of the pig building. The environmental agents measured in the pig building were ammonia, hydrogen sulfide and odor concentration index for gaseous pollutants with temperature and hydrogen sulfide for thermal factors. Results: There were significant differences in the ammonia and odor concentration index in the pig building among the three general ventilation rate conditions(p<0.05), whereas hydrogen sulfide did not show a significant difference among three conditions of general ventilation rate(p>0.05). As the general ventilation rate applied to the pig building increases, it appears that all the indoor environmental agents measured in this study simultaneously decrease. Conclusions: The gaseous pollutants significantly affected by the general ventilation rate in pig building were ammonia and odor concentration index(p<0.05). However, it was found that hydrogen sulfide and thermal factors, temperature and relative humidity were not influenced significantly by variation in the general ventilation rate.

In this experiment, it was attempted to determine the thermal conductivities of earth block materials which are recently much available for farm building constructions in Korea as lower cost building materials. For this experiment, two kinds of earth block materials were sampled. One of them was pure earth and the other was cementstabilized earth with a ratio of earth to cement by volume, 20 to 1. Cylindrical sections of specimen surrounding a steel pipe(I.D. =1 inch) were used. A resistance neater in the pipe and thermometers for the measurement of radial temperature distribution were installed as shown in Fig. 1 and photograph 1. The heat which flows through the pipe and the sample was produced by passing a current through a resistance wire stretched along the pipe axis. The complete apparatus used in this experiment is schematically shown in Fig. 1.
