Improvements in various health indices have been ushered in, along with soaring economic growth in the last few decades in Korea. Life span of Koreans at present stands at somewhere around age of seventies. It seems of worth to elucidate some facets of health profile of historic Koreans during Yi dynasty encompassing about five hundreds years between the 14th and 19th century. Datas on health of historic Koreans are meager with exception for sovereigns for whom royal archives have been preserved intact through centuries. Though the health environments for monarchs are, no doubt, incomparable to that of the grassroot levels during the same period, health profile of monarchs would facilitate to assess health indices for historic Koreans during Yi dynasty. Arithmetic average of life span of 25 consecutive Kings(omitted the last two Kings under Japanese control) is 44.6 years of age 81 year old for King Yongjo and 16 year old for King Danjong, representing two extremes. The principal causes of death are septicemia, subsequent to infections of soft tissue and ether organs(8 in number, one-thirds of all). Secondly, both epidemic disease and vascular accidents caused deaths of three Kings each. Two kings succumbed to diabets and one suicide. The causes for the remainder, eight kings are hardly ciarified. The monarchs who contributed in establishment of new Yi dynasty with highspirited and disciplined survied beyond their fifties and sixties. In contrast, those who reigned during mid - era of the dynasty at its culmination succumbed to death in their young adulthood, most likely due to their indulgence in court life.

This paper researches the system of the official's gongbok(公服) during the reign of emperor Hongwu(洪武帝) in the Ming dynasty, and it is based on DaMingLing(大明令), DaMingJili(大明集禮), HongwuLizhi(洪武禮制), ZhusiZhizhang(諸司職掌), DaMingHuidian(大明 會典), MingTaizuShilu(明太祖實錄), and MingShi(明史). Official's gongbok is consisted of clothes, belt(帶), bokdu, scepter(笏), and black shoes. The system of official's gongbok wa schanged through three stages. First, the system of the Yuan dynasty(元代) was maintained in January, 1368, which was the first year of the emperor's reign. Second, the gongbok system was established in November, 1368. The system stated that the clothes had to be red-colored(赤色) regardless of rank and the belt was divided into okdai(玉帶), seodai (犀帶), gumdai(金帶), and kwangsoeundai (光素銀帶). Third, the system was revised in June, 1391, which was the 24th year of his reign. According to the rank, the clothing colors were divided into scarlet(緋色), blue(靑色), and green(綠色). The belt was divided into okdai, seodai, gumdai, and ogaggai(烏角帶). 'Hongmu26nyunjung(洪武26年定)' recorded on the Wanli's edition(萬曆本) of the DaMingHuidian has the meaning of ZhusiZhizhang regulations.

According to previous studies, the increased air temperature can lead to change of thermal stratification structure of lakes and reservoirs. The changed thermal stratification may result in alteration of materials and energy flow. The objective of this study was to predict the effect of climate change on the water temperature and stratification structure of Daecheong Reservoir, located in Geum River basin of Korea, using a three-dimensional(3D) hydrodynamic model(ELCOM). A long-term(100 years) weather data set provided by the National Institute of Meteorological Research(NIMR) was used for forcing the 3D model. The model was applied to two different hydrological conditions, dry year(2001) and normal year(2004). It means that the effect of air temperature increase was only considered. Simulation results showed that the surface water temperature of the reservoir tend to increase in the future, and the establishment of thermal stratification can occur earlier and prolonged longer. As a result of heat flux analysis, the evaporative heat loss can increase in the future than now and before. However, the convective heat loss and net long wave radiation from water surface decreased due to increased air temperature.

The Netherlands produce more than 11 million tonnes of milk per year, and approximately 60% of the milk is exported. Dutch milk production is five times higher than that of Korea, even though Korea comprises a land area three times greater than the Netherlands. Upscaling and intensification have characterized the Dutch way of dairy farming since 1960, and adverse effects of the intensification of dairy farming became evident from the late 1970s and early 1980s onwards. The transition toward a more sustainable farming system is a central element of the Dutch agenda for the reconstruction of the livestock production sector. The environmental problems in Dutch dairy farming in the 1980s have led to the establishment of the experimental dairy farm "De Marke" which aims at improving the utilization of fertilizers and feeds, through minimizing nutrient requirements, maximizing the use of nutrients in organic manure and homegrown feeds, and through the targeted use of fertilizers and feeds. 85 cows at "De Marke" produce 720 tonnes of milk per year, using 55 ha of pasture in a sustainable manner. That means, 150,000 ha of pasture are required to produce 2 million tonnes of milk, which the current milk production of Korea. It is urgent to provide sufficient pasture for sustainable milk production in Korea, and primarily the transition to pasture of surplus rice paddies, resulting from of a decrease in rice consumption, should be considered.

본 연구의 목적은 당시 당면한 산림문제를 해결하기 위하여 1972년 7월부터 1973년 6월까지 진행되었던 산림정책의 변화과정과 그 원인을 구명하는 데 있다. 1972년에 우리나라가 당면한 산림문제는 1ha 당 평균 입목축적 $11m^3$, 총 산림면적의 약 12%에 해당하는 82만ha의 무립목지로 대표되는 산림황폐화였다. 당시 이 문제를 해결하기 위한 다양한 접근방법이 있을 수 있었다. 1972년 12월 산림개발법이 제정될 때까지는 산림경영 측면에서 조림을 유도하는 경영중심 임정이 유력하였다. 그러나 1973년 3월까지 큰 변화가 있었다. 우선 산림녹화의 효율적인 수행을 위하여 산림청을 농림부에서 내무부로 이관하였다. 뒤 이어 국가가 산림녹화의 주체가 되어 국가 재정과 경찰력을 포함한 행정력을 동원하여 신속히 100만ha를 조림한다는 제1차 치산녹화10년계획이 수립되었다. 영림공사가 수행할 특수개발지역의 산림조차 국가와 지방 정부가 중심이 되어 조림을 한다는 정책이 선택됨으로써 영림공사의 필요성은 퇴색되었다. 더군다나 정부는 법으로 정한 영림공사 설립에 필요한 출자금 200억원을 조달하는 데 '재정적 제약'이 있었다. 결국 공적 기관인 영림공사가 특수개발지역의 산림을 경영한다는 계획은 1973년 3월 5일 산림개발법이 개정되어 영림공사 설립 조항이 삭제되면서 그 막을 내렸다. 이러한 변화의 중심엔 당시 산림문제를 단기간 내에 해결하려는 박정희 대통령의 '시간적 제약' 인식이 크게 자리 잡고 있었다. 이런 대통령의 인식은 영림공사 주도의 조림정책보다 행정력 주도의 제1차 치산녹화10년계획을 선택하게 만든 보이지 않는 변수였다.
