Objectives: This study was conducted to investigate the actual condition of the farm work environment and personal protective equipment as part of the effort to improve livestock work for the safety and health of poultry farmers and provide basic data for establishing plans to improve and develop personal protective equipment. Methods: For this purpose, a questionnaire survey on general information about stables, the poultry work environment, accidents, the wearing of work clothes and personal protective equipment, and the level of awareness related to personal protective equipment was conducted among 148 poultry farmers. Results: As a result, it was found that poultry workplace environment was exposed to such risks as fine dusts; organic dusts; poisonous gases; odorous substances; chicken excrement; contact with chickens, bacteria or viruses; and accidents related to machine operation. Thirteen percent of respondents suffered severe respiratory diseases, and the most frequently injured sites due to accidents were the hands (25.7%), knees (23.8%), arms (17.3%), and head (10.9%). The most frequent type of accident was collisions between the body and obstacles or machinery during movement (36.4%), followed by erroneous machine operation such as feeders and electric shocks (8.5%). Regarding the wearing of work clothes and personal protective equipment, 51.7% of the respondents wore worn-out clothing or everyday clothes, whereas only 32.0% wore work clothes. The percentage of farmers who wore proper protective equipment for the work environment during poultry work was 48.4%. The most frequently used type of protective equipment was boots (38.9%), followed by mask (36.7%), gloves (36.3%), appropriate work clothes (22.6%), quarantine clothes (17.6%), helmets (13.4%), and goggles (12.6%). The rate of wearing goggles was low because they were considered inconvenient and lowered work efficiency. Furthermore, they purchased everyday products available on the market for their personal protective equipment which were not appropriate for maintaining safety in an actual harmful environment and its consequent risks. As a result of the survey of the awareness level related to personal protective equipment, their levels of awareness of accidents and attitude proved to be average or higher, but the practice of wearing protective equipment and the level of knowledge and management of personal protective equipment were lower. Conclusion: This survey found that the wearing status of personal protective equipment among poultry farmers was insufficient even though they were exposed to risks. Most respondents were aware of the necessity of wearing personal protective equipment and of the potential for accidents, but they did not wear proper protective equipment. Their wearing rate was low due to a lack of knowledge about protective equipment, as well as the inconvenience of wearing it. Therefore there is a need to improve and develop specialized personal protective equipment for respiration, hands, and eyes, as well as work clothes that can protect farmers from major harmful matter that is generated in the poultry workplace. Based on the results of this investigation, we will conduct further studies on the required performance and design directions of personal protective equipment while collecting more objective data through field-oriented assessments.

본고에서는 김정은과 북한 권력엘리트 개인의 관계를 측정할 수 있는 지표를 개발하여 북한 정권의 특성을 분석해보았다. 먼저 김정은의 현지지도 동향(2012-2015)에 대한 요인분석(factor analysis)을 실시한 결과 북한 권력엘리트는 장성택 처형 이전에 현지지도를 자주 수행하는 인원과 장성택 처형 이후에 현지지도를 자주 수행하는 두 집단으로 구분되었다. 본고에서는 장성택 처형 이전과 비교하여 장성택 처형 이후에 현지지도 수행빈도가 상대적으로 증가한 인원은 김정은과 친화성이 높다고 보고, 현지지도 수행 빈도의 변화를 중심으로 김정은 친화성 지수를 산출하였다. 김정은 친화성 지수를 토대로 북한의 권력엘리트를 분석해본 결과 장성택 처형 이후 북한 권력구조에 급격한 변화가 발생하지 않았으며, 이에 따라 김정은 정권은 안정적인 것으로 평가되었다. 그 이유는 다음과 같다. 첫째, 김정은 친화성이 매우 크거나 낮은 인원, 즉 장성택 처형 이후 현지지도 수행 빈도가 크게 변화된 인원이 많지 않았다. 이는 장성택 처형이 북한 권력층에 미친 영향이 크지 않았음을 의미한다. 둘째, 김정은 친화성 지수가 매우 높은 인원과 김정은 친화성 지수가 매우 낮은 인원의 직책이 동일했다. 이는 장성택 처형 이전과 이후에 현지지도를 자주 수행하는 인원의 직책이 동일하다는 것을 의미하며, 이를 통해 북한의 정책 기조에 큰 변화가 없다는 사실을 확인할 수 있다. 셋째, 당중앙군사위원회 및 국방위원회 위원들의 김정은 친화성 지수가 다른 인원들에 비해 높았다. 이는 군 중심의 북한 권력구조가 유지 또는 강화되고 있다는 사실을 반영한다. This study aims to develop a quantitative index, which can be used to measure intimate relationship between North Korean leader Kim Jong-un and North Korean power elites. This study suggests Kim Jong-un Affinity Index(KAI) on the basis of factor analysis on 202 North Korean elites who have appeared more than once in Kim Jong-un`s field inspection (2012-2015). KAI indicates when between before and after the execution of Jang Sung-taek one North Korean power elite is likely to accompany Kim Jong-un. If it is taken into account that North Korean leader let his proteges to accompany field inspection, those who have a higher KAI can be assumed to have a close relation with Kim Jong-un. Major findings go as follows. First, results of factor analysis showed that North Korean power elite can be statistically significantly categorized into two groups: the first group who is likely to accompany field inspection before the execution of Jang and the second group who is likely to do so after the execution of Jang. Second, those who have been considered to have a close relationship with Jang had statistically significantly higher KAI, while those who have been considered to have a close relationship with Kim had statistically significantly lower KAI. This study then used KAI to analyze the characteristics of Kim Jong-un regime and found that Kim Jong-un regime is relatively stable for three reasons. First, the number of North Korean power elites who have relatively higher or lower KIA is small. Contrary to expectation from existing literature, this is to say that Jang Sung-taek did not has a large group of proteges. Second, there is little difference in the positions that North Korean power elites with relatively lower KAI and North Korean power elites with relatively lower KAI assumed. Results indicates that the positions playing a critical role in decision-making process have not changed. Finally, comparing KAI by North Korea`s party and government organizations, the Party Central Military Commission and the State Affairs Commission had statistically significantly higher mean score of the KAI. Therefore, it is not difficult to conclude that North Korean power structure centering around the military is maintained or strengthened.

Objective: This study developed working clothes using a vortex tube device to reduce the thermal stress of greenhouse workers, and evaluated the physiological effects and user satisfaction of the developed cooling vest. Background: During the summer, the inside of greenhouses causes increased physiological burden of workers due to a high temperature and humidity, causing accidents and lowering the work efficiency. As a measure to solve this problem, various working clothes to lower thermal stress have been researched and developed, but there were limitations in the development of working clothes appropriate for high temperature and humidity in greenhouses. Therefore, the development of a new agricultural working clothes is required to prevent thermal stress of workers in a warm environment. Method: To verify the thermal stress reduction effect of the farming vest applying a vortex tube device, a physiological evaluation test was performed for subjects in a climate chamber and greenhouse environment. In addition, the wearing satisfaction and field applicability of the developed working clothes was evaluated by farmers. Results: The results of analyzing the mean physiological reactions by body part in the climate chamber test, the skin temperature, mean temperature in the working clothes, mean humidity, and heartrate of the developed working clothes decreased by 2.9%, 8.1%, 35.5%, and 4.9%, respectively, compared to the existing working clothes. Furthermore, in the greenhouse environment test, the temperature in the working clothes and humidity of the developed working clothes decreased by 8.8% and 12.3%, respectively, compared to the existing working clothes. Furthermore, in wearing sense and user satisfaction survey for farmers in the field evaluation, the respondents showed positive responses. Conclusion: This study verified the effects of the agricultural working clothes applying the vortex tube technology had an effect of thermal stress reduction compared to the existing working clothes and its applicability to the agricultural work environment. Further practical research should be conducted considering the cultivation environment and the size of greenhouse facilities to develop working clothes for various work environments. Application: The results of this study are expected to be utilizable in the field of design of thermal stress reducing working clothes for greenhouse facility farm workers.
