우리나라보다 고위도 저온 지역인 북한과 중국 동북3성에서 재배되는 자포니카 벼 품종의 등숙적온이 더 낮은지를 밝히기 위하여, 국립식량과학원 중부작물부(수원) 벼 재배시험 포장과 인공기상실에서 등숙기간 중 기온을 조절하여 2년간 시험한 결과는 다음과 같다. 1. 포장시험에서 백미중 향상을 위한 출수 후 40일간 등숙 적온은 북한 품종에서 22.6~23.0℃, 중국 동북3성 품종에서 21.5~22.3℃로, 남한 품종의 21.5~23.6℃에 비해 낮지 않았다. 2. 2017년 1차 이앙에서 북한 품종 중 길주1과 중국 재배 품종은 남한의 오대 대비 출수기가 7~12일 빨랐다. 3. 인공기상실에서 개화 수정 후 수확기까지 동일한 온도 조건으로 평균기온을 16~22℃로 처리하여 검토한 결과, 남한 품종 중 삼광과 북한 품종 중 평양21을 제외한 7품종에서 백미중은 처리간 유의한 차이가 없어 평균기온 16℃까지 잠재 등숙성이 유지되었다. 4. 포장시험에서 품종별 상관식에 출수 후 40일간 평균기온 16, 18, 20, 22℃를 대입하여 분석한 백미중 지수는 인공기상실 시험과 다르게 22℃보다 기온이 낮아짐에 따라 급격하게 저하되었다. 5. 대부분의 품종에서 수확기경에 평균기온 10~16℃ 사이가 유지된 조건에서 백미중이 가장 높았고, 16℃보다 높거나 10℃보다 낮아지는 조건에서는 수량이 저하되었다. 6. 종합적으로 우리나라보다 고위도 저온지역에서 적응하는 벼 품종의 특성은 낮은 등숙적온이 아니라 짧은 생육 기간이며, 포장 조건에서 나타나는 벼의 등숙적온은 온대기후 특성상 등숙후기에 기온이 저하되는데 원인이 있는 것으로 해석되었다.

BACKGROUND: Inorganic component is made up largely of salt, because the criteria are difficult to split into domestic and imported ingredients, organic examined the fatty acid composition is to see a possible use as a marker using gas chromatography-mass spectrometry (GC-MS). The 14 domestic samples and 8 imported samples were collected from China, India and other countries were investigated on item of 37 fatty acids. METHODS AND RESULTS: The major components were six species, myristic acid ($C_{14:0}$), palmitic acid ($C_{16:0}$), palmitoleic acid ($C_{16:1}$), stearic acid ($C_{18:0}$), oleic acid ($C_{18:2,n9}$), linoleic acid ($C_{18:2,n6}$) among detected twenty fatty acids including 9 unknowns. The content of palmitic acid were highest as 25.2 to 50.8% of total fatty acids contents. Domestic has seen the most amount of salt in the Taepyeong salts $250.8{\mu}g$/100g, imports $135.2{\mu}g$/100g salt in Chinese Weifang salts showed the lowest content. CONCLUSION(s): The total fatty acid content has seen the most amount of salt in 352.3 ug/100g Christmas island salts showed the lowest content of $164.0{\mu}g$/100g, as a result it is difficult to distinguish the domestic salts and imported by the composition of fatty acid.

In China, primary purpose of policy concerning land tenure system was to maintain social homogeneity among people and growth of productivity. Even before reformed by Deng Shao Ping's government, left wing who had placed more importance on the social unity. When they gained political power, pressing against market oriented agricultural policy for the collective farming system. However right wing prefered to adopt the productivity oriented policy, which might lead to individualized farming system at the cost of social unity. Since Chinese government following principles of social economy put more weight on social unities rather than productivity growth, farming system and rural community became developed into homogeneous structure across the nation before Deng Shao Ping's reform. Process for People's Commune, followed by first and then second level coperations starting from group farming so called Hozozo, was historical reflection of developing such land tenure system. However, even under People's Commune, farmers' efforts could be found to increase their own productivity along with emerged private farming, in which Posandoho with week private farming system was gradually developed into Pogandoho. As Deng's government encouraged farmers to increase productivity through the market oriented measure, there had been wide spread of Pogandoho among the farmers even before legal desolution of Peoples' Commune was realized.

Lyme disease, or Lyme borreliosis. is an infection caused by spirohete Borrellia burgdorferi. This disease was recognized in Lyme, Conneticut U.S.A. in 1975. The onset of the disease is usually heralded by the appearance of a pathognomic skin lesion, known as erythema chronicum migrans, and accompanied by flue like or meningitis like symptoms. Unless treatment is initiated early, the disease usually disseminated, often resulting carduac, neurologic, or joint manifestations. All stages of the disease are usually curable by appropriate antibiotic therapy, and can prevent severe late cardiac, neurologic, and joint complications. Lyme disease is typically defined by clinical evidence supported by serologic test. The diagnosis require serologic confirmantion of erythema chronicum migrans, occurring in patient in nonendemic countries. Determination of antibody titer against B. burgdorferi by enzyme linked immunosorbent assay(ELISA) currently the most practical diagnostic test. Currently Lyme disease occurs in U.S.A. Europe, and Australia. It has recently recognized in China, Japan, and Soviet Union also. In United States, Lyme disease is most common vector borne infection. There is no reported case of patients with this disease in Korea. But the vector of this disease, -Ixodes ticks- had been identified in Korea. And Korea is geographically closely related to China and Japan where Lyme disease is already reported. We expect first case of Lyme disease could he reported in near future. We review the clinical manifestations and diagnostic method of Lyme disease.

Covering an area of about 39 ha, Qingming Shanghe Park is located in the northwest of Kaifeng, formerly the capital of seven dynasties in China. It is intended to serve as a tourist attraction based on a painting 〃Qingming Festival at Riverside〃 by Zhang Zeduan of the Northern song Dynasty, which vividly illustrates a real life on the both sides of the Bian River as well as in the urban area, Kaifeng, in early Spring. The park is a collection of varied buildings such as shops, restaurants, tea-houses, theaters, and hotels in the North song style, with an introduction of the history of Kaifeng, this paper examines design philosophy and methodology of the park, and discusses the creative design of the first stage development known as known as The South Area of the park. Marked by the Rainbow Bridge and the City Gate, the South Area is divided into three parts, the rural, suburban, and urban parts which are organized according to the spatial order showed in the painting. The South Area proves to be very successful because of its amazing sense of history and interesting folk performance. Furthermore, the preliminary 9planning of the second stage development known as The North Area is presented with references to culture, history and customs. The North Area is proposed to include the Old Sports & Games Garden, the Exhibition Garden, and the Hot Spring Garden with an appearance of the imperial gardens in the Northern Song, integrated with participation of old sports and games, display of old science & technology achievements, and enjoyment of hot spring bath.

Recently the North Korea has been suffered from the grain shortage, and the fundamental reason was in the socialistic land regulations and collective production which restrain farmers' labor desire. So one of the key in solve the problem may be in the reformation of the socialistic land regulations and collective production, however, the capitalistic land regulations may not work as the reformational alternative in the North Korea. The third alternative for land should consider efficiency and equality of reformation itself as well as environmental problems. The purpose of the study was to discuss the possible application of the Public Land Lease from Henry $George(1839{\sim}1897)'s$ theory. The basic idea of the Public Land Lease was that the government has the right of sentence and the right of profit for the land, and the individual has the right of use for the land. Under the Public Land Lease, the individual must pay the land rent for the period of the use for land, and must return the land when the contract is over. If the North Korea's rural land regulations reformed into the Public Land Lease, it would be the first reformational model beyond china.

Precipitation samples were collected at sixteen sites in Northeast Asia from June 1995 to February 1997, and were analysed for the anions $SO_4^{2-}$, $NO_3^-$and $Cl^-$ and for the cartons $Na^+, NH_4^+, K^+, Mg^{2+} and $Ca^{2+}$in addition to pH and conductivity measurements. The quality assurance of chemical composition data was checked by considering the ion balance evaluating by 1 h 1 value and the conductilfty balance. The sum of cation concentrations were slightty greater than the sum of anion concentraions. For the anions, $SO_4^{2-}$ clearly dominates in most of sampling states whereas $Cl^-$ is more abundant in coast and rural sites In. Tapan. For the cations. $Ca^{2+}$ and $NH_4^+$ are generally the more abundant tons except when sources of Na+ exist. The contribution rate of nss-$SO_4^2-and NO_3^-$ to acidity are about 70% and 10-30%. respectively. The neutralizing capacity by a major neutralizing cations such as $NH_4^+$ and nuts -$SO_4^2$. are above 98%(heavy polluted and urban sites in China), above 70%(urban sites in Japi,n and in Korea, coast sites In Chinas and above 60%(rural sites in Japan and in Korea), respectively.

This study examines the process of urban formation in the city of Yanji. The analysis is done by the change of street pattern and major facility location in a timely manner by appling space syntax method. This research categorizes the pattern of the urban growth focused on two urban forms, street and major buildings, in the city and is offered of the meaning of the first value on interpretation of the urban growth in the city of Yanji. The result of the research are as follows. First, the period of the city transformation is divided into four stage; intuitive period, grid-iron formative period, consolidation period, and urban expansion period. Second, characteristics of each stage have been analyzed. At the first stage, the city started to frame along both buildings and streets which were placed without a plan. At the second stage, the city was planned and constructed into new grid-iron pattern ignoring existing context by Jananese colony. At the consolidation period, the road system expands from the city center toward suburban. At the last expansion period, the shape of the city has complicated its shape with complex road system. This study contributes to provide a basic analysis and data to investigate how the Yanji city has evolved over period of time. But further continuous research should be done for future urban development of the Yanji city.

This paper takes Zhaoxing Dong village in Guizhou Province as the research object. The purpose is to study the continuity of landscape context in Dong Village. The research process includes specification on the evaluation system of Dong village landscape context by AHP method, and use of the questionnaire survey method in sequence, according to the specific situation of Zhaoxing Dong village, and this study develops a specific questionnaire that modifies the evaluation system suited to reflect specific problems. Through the analysis of the specific questionnaire and recycling in Zhaoxing Dong village, this study found that Zhaoxing Dong village as a whole is over commercialized due to the vigorous development of tourism service industry. As a result, whether it is experts, foreign tourists or local villagers, the rating of the village landscape is low. There are three problems in the village landscape context: historical continuity, invisible cultural heritage and contradiction in protection and development. The results of this paper provides a future direction for the protection and inheritance of Zhaoxing Dong village.
