After world war Ⅱ Japanese life expectancy has been improved remarkably, and reached the highest level in the world around late 1970's. The life expectancy of Korean has also shown tremendous improvement in recent years with about 20 year's gap from the Japanese. The reason of rapid improvement of life expectancy can be explained by changes in the structure of cause of death due to health system, living standard, social welfare, health behavior of individuals and so on. Korean in Japan is placed under different situations from both Korean in Korea and Japanese in these regards, and expected to show different picture of cause of death pattern. The objective of this study is the comparision of changing patterns of cause of death of three population groups, Korean in Japan, Korean in Korea and Japanese, and to investigate the reasons which effect to the structural difference of mortality cause with special emphasis on health ecological aspects. One of the major limitations of the Korean causes of death statistics is the under-registration which ranges about 10% of the total events, and inaccuracy of the exact cause of death. Some 20% of registered deaths were unable to classify by ICD. However, it is concluded that the Korean data are evaluated as sufficient to stand for over-viewing of trends of cause of death pattern. The evaluation is done by comparing data from registration and field survey over the same population sample. Population data of Korean in Japan differ between two sources of data; census and foreigner's registration. Correction is done by life table method under the assumption that age-specific mortality pattern would accord with that of the Japanese. The crude death rate was lowest among Korean in Japan, 5.7 deaths per 1,000 population in 1965. The crude death rates of Korean in Japan and Japanese are increasing recently influenced by age structure while Korean in Korea still shows decreasing tendency. The adjusted death rate is lowest among Japnaese, followed by Korean in Japan, and Korean in Korea. The leading causes of death of Korean in Korea until 1960's was infectious diseases including pneumonia and tuberculosis. The causes of death structure changed gradually to accidents, neoplasm, hypertensive disease, cerebro-vascular disease in order. The main difference in cause of death between Korean and Japanese is high rate of liver diseases and diabetes for both Korean in Japan and Korea. A special feature of cause of death among Korean in Korea is remakably high rate of hypertensive disease, which is assumed to be caused by physicians tendency in choosing diagnostic categories. The low ischemic heart disease and high vasculo-cerebral disease are the distinctive characteristic of the three population groups compared to western countries. Specific causes of death were selected for detailed sex, age and ethnic group comparisons based on their high death rates. Cancer is the cause of death which showed most drama tical increase in all three population groups. In Korea 20.1% of all death were caused by cancer in 1990 compared with 10.5% in 1981. Cancer of the liver is the leading cause of cancer death among Korean in Japan for both sexes, followed by cancer of the lung and cancer of the stomach, while that of Korean in Korea is cancer of the stomach, followed by cancer of the liver and cancer of the lung for male. Causes of infant mortality were examined among the three population groups since 1980 on yearly bases. For both Japanese and Korean in Japan, leading cause of death ranks as conditions originating in the perinatal period, congenital anomalies, accidents and other violent causes. Trends since 1980 for these two population groups in the leading cause of infant mortality showed no changes. On the contrary, significant changes in leading cause of death structure in Korea were observed : The ranking of leading cause of death in 1981 were congenital asnomali

The purpose of this study is to investigate the propriety of TMA clathrate as a cold storage medium. Particularly, this is to examine the extent of subcooling improvement when the surfactants are added to the TMA clathrate, because water used cold storage material has low phase change temperature and subcooling. This study has been analyzed and compared with TMA 30wt% clathrate how phase change temperature, subcooling and specific heat in the various concentrations are changed. This results view to be improved phase change temperature and subcooling of TMA30wt% as a cold storage medium, when it had some surfactant. Additionally, it is that surfactant must be controlled under available solution limit and study for new additive must be lasted to know its effect.

부동산 투기예방을 위한 대토보상제도 활성화 방안 연구 - 토지보상법 개정 필요성 중심으로 -

박창률(Park, Chang Yul),박정준(Park, Jung Jun),손순금(Son, Sun Gum) 한국지적정보학회 2021 한국지적정보학회지 Vol.23 No.2

대토보상이란 원주민의 토지가 공공개발사업구역에 편입되어 토지보상금 대신에 사업지구내의 개발이 완료된 후 현금대체보상수단으로 당해지구의 토지로 보상받는 권리를 대토보상이라고 한다. 원주민이 보상금대신 토지로 보상받는 권리는 토지보상법 제63조의 법적으로 정당한 권리이다. 그러나 현실의 대토보상제도는 각 사업지구의 토지보상실적을 보면 활성화 되지 못하고 있다. 그 원인은 여러 가지 복합적인 원인이 있지만 정부가 정책적으로 대토보상 활성화정책이 필요한 부분으로 정책적 문제는 연구의 대상에서 제외 하였다. 제도적인 문제에서 토지보상이 활성화를 위한 「토지보상법」제 63조제1항에서 제3항까지의 개정이 필요한 것이다. 법이 개정이 되어야 사업의 시행자(정부공기업 또는 지방공기업)의 대토보상 시행지침이 바뀌게 될 것이다. 본 연구의 목적은 토지보상법이 개정으로 인하여 대토보상 제도를 활성화 하고 신도시 개발지역의 부동산투기를 예방하고 더불어 개발지역의 원주민의 재정착기회와 개발이익을 향유할 수 있는 근본적인 대책을 강구하는 연구다. 더불어 사업의 시행자는 법의 규정에 앞서 개발지역 원주민의 특성(수도권, 비수도권)을 고려한 대토보상이 이루어져야 원주민의 재정착과 개발이익일부를 원주민에게 돌려주는 방안이 나올 것이다. Land compensation refers to the right of indigenous people to be compensated with land in the district as a means of cash replacement compensation after development in the project zone is completed. Indigenous people"s right to compensate with land in place of cash compensation is a legally valid right under Article 63 of the Land Compensation Act of Korea. However, the real land compensation system has not been activated based on the land compensation performance of each business district. There are a number of complicated reasons for this, but policy issues were excluded from the study as part of the government"s policy of promoting land compensation. In institutional matters, it is necessary to revise Articles 63 (1) through (3) of the Land Compensation Act for the Promotion of Land Compensation. Only when the law is amended will the implementer"s guidance on land compensation be changed. The purpose of this study is to revitalize the land compensation system due to the revision of the Land Compensation Act, prevent real estate speculation in new town development areas, and devise fundamental measures to enjoy resettlement opportunities and development profits. In addition, the implementer of the project will return some of the indigenous people"s resettlement and development profits to the indigenous people only when compensation is made in consideration of the characteristics of the indigenous people (metropolitan and non-metropolitan areas) before the law.

Rice transformation method using A. tumefaciens has already been widely used to generate transgenic plants, the transformation rate is still low in most Korean elite cultivars. We made several modifications of the standard protocol especially in the co-cultivation step to improve the efficiency of the rice transformation. The co-culture medium was modified by the addition of three antioxidant compounds (10.5㎎/ℓ L-cysteine, 1mM sodium thiosulfate, 1mM dithiothreitol) and of Agrobacterium growth-inhibiting agent (5㎎/ℓ silver nitrate). Co-cultivation temperature (23. 5℃ for 1 day, 26.5℃ for 6 days) and duration (7 days) were also changed. The plasmid of pMJC-GB-GUS carrying the GUS reporter gene and the bar gene as the selectable marker was used to evaluate the efficiency of the transformation. After co-cultivation, a high level of GUS gene expression was observed in calli treated with the modified method. It is likely that those newly added compounds helped to minimize the damage due to oxidative bursts during plant cell-Agrobacterium interaction and to prevent necrosis of rice cells. And the transformation rate under the modified method was also remarkably increased approximately 8-fold in Heungnambyeo and 2-fold in Ilmibyeo as compared to the corresponding standard method. Furthermore, we could produce the transgenic plants stably from Ilpumbyeo which is a high-quality rice but its transformation rate is extremely low. Transformation and the copy number of transgenes were confirmed by PCR, bar strip and Southern blot analysis. The improved method would attribute reducing the effort and the time required to produce a large number of transgenic rice plants.

Lb. plantarum AF1이 생산한 조항진균 물질 부분 정제물의 경구투여 결과 체중이 4주간 지속적으로 증가되었지만 대조군과 유의성 있는 변화가 없었다. 또한 장기의 육안적 관찰, 장기 중량변화,혈액학적, 혈액생화학적 및 병리조직학적 검사에서도 모든 시험물질 투여군이 대조군과 유의성이 있는 차이를 보이지 않았으며, 모두 정상 범위의 수치로 시험물질에 기인하는 이상 소견을 발견할 수 없었다. 이상의 결과 4주 반복투여 독성시험 결과 Lb. plantarum AF1이 생산한 조항진균 물질 부분 정제물은 저독성의 안전한 물질로 판정되었다. This study was performed to investigate the four-week repeated-dose toxicity of the crude antifungal compounds produced by Lactobacillus plantarum AF1 (Lb. plantarum AF1), a lactic acid bacterium isolated from kimchi, in male and female rats. Sprague-Dawley male and female rats were divided into four groups, with 10 animals in each group. The test article was administered once daily by gavage to rats at dosage levels of 0, 500, 1,000, and 2,000 mg/kg/day for four weeks. There were no test-article-related deaths or abnormal clinical signs in both the male and female rats during the observation period. Furthermore, no differences in the body weight changes, food intake and water consumption levels of the control and treatment groups were found. The hematological parameters, serum biochemical analysis results, histopathological examination results and all other findings also showed no significant or dose-dependent changes. There were also no changes in the organ weights upon the administration of the crude antifungal compounds produced by Lb. plantarum AF1. These results suggest that the oral administration of the crude antifungal compounds produced by Lb. plantarum AF1 had no adverse effects up to a dosage level of 2,000 mg/kg in both male and female rats.

This study was undertaken to define the effect of Oplopanacis Cortex on the phenylephrine-induced arterial contraction and the mechanism of Oplopanacis Cortex-induced relaxation. In order to investigate the effect of Oplopanacis Cortex on contracted rabbit carotid arterial strips, transverse strips with intact or damaged endothelium were used for the experiment using organ bath. To analyze the mechanism of Oplopanacis Cortex-induced relaxation, Oplopanacis Cortex extract infused into contracted arterial strips induced by phenylephrine after treatment of indomethacin, tetraethylammonium chloride or N_(t) nitro-_L-arginine. The relaxation of Oplopanacis Cortex was dependent on the presence of endothelium, showing that Oplopanacis Cortex-indeced relaxation was not observed in the strips damaged endothelium. The endothelium-dependent relaxation induced by Oplopanacis Cortex was suppressed by the pretreatment of N_(t) nitro-_L-arginine, but it was not observed in the strips pretreated or tetraethylammonium chloride. These result demonstrated that Oplopanacis Cortex may inhibit phenylephrine-induced constraction through the production of nitric oxide in the vascular endothelial cells.

The resonant frequency of the dielectric rod resonator which is surrounded by cylindrical cavity can be calculated very exactly by using eigenfunction expansion method in the concept of electric and magnetic wall from the symmetry. But if the supporter is put in the cavity, the symmetry disappears. Thus this method has some errors. In this paper, the resonant frequency of the asymmetric dielectric rod resonator was calculated by using the eigenfunction expansion method. Also, the effect of the supporter was discussed. Then we found that the resonant frequency was more affected in the case of TM mode than TE or Hybrid modes as the length of the supporter was longer.

Adaptive Scheme에 의한 평면응력 유한요소망의 자동형성화에 관한 연구

The finite element method(FEM) has been widely accepted as one of the most powerful analytical techniques in solving complex engineering problems. In using a FEM program, the results of analysis depend on the finite element mesh. Expertise and experience are required in forming an efficient mesh. Adaptive mesh generation is the process automatically forming an efficient mesh by moving existing nodes, subdividing elements, or increasing the order of polynomials used in the shape functions. As the scheme depends on the error estimates used to evaluate the meshes, the definition of error estimator affects the quality of the final mesh. In this study, a simple error estimator is developed and a new approach for combining different errors is proposed. Plane stress problems are considered. The r method, which is the scheme where nodes are moved, the h method, which is the scheme where elements are subdivided and the rh method, which is the scheme that combines r and h method, are investigated in this study with the proposed error estimator. The proposed error estimator is constituted from the domain and the boundary errors. The difference of stresses in the domain of an element and the difference of strains on the boundaries between the element and its neighboring elements are used as error estimators. Each error is normalized and the final error estimator is the weighted sum of each error. The analysis results using the adaptive mesh obtained with the proposed error estimator are compared to the exact solution. The comparisons show that the proposed error estimators are good error indicators for generating efficient final meshes in the applied examples. The generated final meshes use less number of elements than fine mesh and obtained same result of analysis.
