This study was carried out for the stability analysis of earth dam by the variation of compaction density. The test samples were taken from five kinds of soil used for banking material and the degree of compaction for this samples were chosen 100, 95, 90, 85, and 80 percent. The stability problems were analysed by the settlement and camber( extra banking) of dam, strength parameter and dam slope, and coefficient of permeability and seapage flow through dam body. The results of the stability analysis of earth dam are as follows. 1. The more the fine particle increases and lower the compaction degree becomes, the lower the preconsolidation load becomes but the compression index becomes higher. 2. Sixty to eighty percent of settlement of dam occurs during the construction period and the settlement ratio after completion of dam is inversly proportional to the degree of compaction. 3. The camber of dam has heigher value in condition that it has more fine particle(N) and heigher dam height(H) with the relation of H= e(aN-bH-e). 4. The cohesion(C) decreases in proportion to compaction degree(D) and fine particle(N) with the relation of C= aD+ bN-c, but the internal friction angle is almost constant regardless of change of degree of compaction. 5. In fine soil, strength parameter from triaxial compression test is smaller than that from direct shear test but, they are almost same in coarse soil regardless of the test method. 6. The safety factor of the dam slope generally decreases in proportion to cohesion and degree of compaction but, in case of coarse soil, it is less related to the degree of compaction and is mainly afected by internal friction angle. 7. Soil permeability(K) decreases by the increases of the degree of compaction and fine particle with relation of K=e(a-bl)-cN) 8. The more compaction thickness is, the less vertical permeability (Kv) is but the more h6rzontal permeability (KH) is, and ratio of Kv versus KH is largest in range from 85 to 90 percent of degree of corn paction. 9. With the compaction more than 85 percent and coefficient of permeability less than ${\alpha}$X 10-$^3$cm/sec, the earth dam is generally safe from the piping action.

From the reunification of Germany we can learn much for the reunification of Korea. That particularly applies for the dispute resolution of the trade relations between both states. The domestic trade relation, which was the only contractually regulated relation between two states for a long period of time, played a crucial role in the reunification of Germany, In this research paper, we examine how the economic disputes in divided Germany had been settled, and consider for the amicable economic relations between south and north Korea, what can we learn from that. In Germany, the disputes from the trade relations could be settled via the civil procedure, because the judicial codes of both German states were the same until 1975, However, that does not apply in Korea, as two Koreas have another law and another court system, from the start. We argue that arbitration is the best way for the completion of the economic disputes. Besides the general advantages of the arbitral procedure, the arbitration is particularly suitable to regulate the economic disputes from Korea-Korea relations, because of glaring differences of the legal status and reality of both countries. Furthermore, the standing arbitral tribunals would be in the economic relations between two Koreas more effectively than the ad-hoc arbitral tribunals. The ad-hoc arbitration generally requires a lot of time to setting up an arbitral Oibunal. For the rapid and obligatory settlement of dispute, the Convention of Currency, Economic and Social Union between West and East Germany 1990(Staatsvefrag zur Wahrungs-, Wirtschafts- und Sozialunion zwischen der Bundesrepublik und der DDR) also planned the institutional arbitration. The organizational support of the internal-Korean arbitration can take place via already existing institution, namely in south Korea 'The Korean Commercial Arbitration Board' Periodic decision reports and publication of substantial awards at the early stage seem appropriate.

The purpose of this study is to understand a term of 'Jangbu theory 臟腑論' in 'Dong-Eui-Su-Se-Bo-Won 東醫壽世保元'. The conclusion would be summerized as follows. 1. 'Jangbu theory 臟腑論' of 'Sa-Sang medicine 四象醫學' is based on 'Sa-Sang structure 四象構造'. 2. 'Mind 心' of 'Sa-Sang medicine 四象醫學' is recognised as the Lord of body. 3. 'four-Jang 四臟' and 'four-Bu 四腑' constitute 'Sa-Sang structure 四象構造' which is based on the deviation of 'vital energy 氣', and 'four-Jang 四臟' plays a loading role. 4. 'Sacho 四焦' explains the whole function of human body including one's heart's desire, physical constitution and the visceral physiology. 5. 'ear-eye-nose-mouth 耳目口鼻' is connected with 'the profound secrets of nature 天機' and also has a close relation with creation of 'spirit-vital energy-blood-essence 神氣血精' and spiritual fuction. 6. 'SaHae theory 四海論' of 'Dong Mu 東武' is philosophical concept set on the basis of 'nature 天性' and 'life 人命'. 7. 'spirit-vital energy-blood-essence 神機血精' doesn't have the relation of mutual transformation. It's creation and consumption lies on 'the power of ear-eye-nose-mouth 耳目口鼻之力'. 8. 'Sa-Sang medicine 四象醫學' expands its theory centering on the deviation of 'vital energy 氣' and the transversal circulation of 'SaHae 四海' According to the above result, 'Jangbu theory 臟腑論' in 'Dong-Eui-Su-Se-Bo-Won 東醫壽世保元' should be understood on the basis of 'Sacho 四焦' and 'SaHae 四海' according to 'Sa-Sang structure 四象構造', accompanying philosophical thinking focused on human and society, the centural concept of 'Jangbu theory 臟腑論' could be said as 'Mind 心' to be the Lord of body.

This study was aim to provide rheumatoid arthritis patients the basic data of development of nursing intervention to help psychosocial adaptation of rheumatoid arthritis patients as exploring the relationship among causal perception, coping pattern, psychosocial adaptation of rheumatoid arthritis. As the results of this study the mean score of causal perception of the subjects was 3.37. The score of the internal-unstable was the highest. which was followed by extra-stable, internal factor, internal-stable, external factor and external-unstable in order among the factor of causal perception. The mean score of coping pattern was 2.64. The type of coping patterns the score of the receptive coping was the highest, which was followed by wishful coping active coping and negative coping in order among the type of coping pattern. The mean score of psychosocial adaptation was 3.28. The subconcept of psychosocial adaptation the score for personal relationship was the highest, which was followed by role function and mental state in order among the psychosocial adaptation. The analysis of the relation among causal perception, coping pattern and psychosocial adaptation showed significant negative correlation between causal perception and psychosocial adaptation(r=-0.3219, P=0.002). The analysis of the relation between the type of coping pattern and psychosocial adaptation showed significant negative correlation between psychosocial adaptation and active coping(r=-0.3210, P=0.002), negative coping(r=-0.2296, P=0.032). Only causal perception(-.36) and period of illness(-.26) effected on the psychosocial adaptation were shown to the negative direction significantly. The psychosocial adaptation was explained the 17% by these two variables. Based on this study results the factor of causal perception and the type of coping pattern of rheumatoid arthritis were shown significant relations between psychosocial adaptation. We suggests that nurses in practice apply to assessing the factor of causal perception of individuals illness and the type of coping patterns when nursing interventions in rheumatoid arthritis patients.

Objectives : This study is about a comparison of controlled and uncontrolled hypertension groups regarding pulse shape and quality of life. We aimed to find out if pulse shape would be able to help with hypertension treatment and care. Methods : We surveyed "controlled and uncontrolled hypertension patients" using SF-36, HTN QoL (measurement scale for the quality of life in hypertensive patients) and 3-D MAC pulse analyzer for pulse shape. Results : The uncontrolled hypertension group tended to have a sink pulse in the left cun. right guan & chi parts compared to the controlled hypertension group. Within the controlled hypertension group, patients who had a float pulse shape in both guan parts had a higher quality of life than patients who had a normal pulse shape. And the patients who had a normal pulse shape in both chi parts had a higher quality of life than patients with a slow or fast pulse shape. Within the uncontrolled hypertension grouP. the patients who had a normal pulse shape in right guan part had a higher quality of life than those with a choppy pulse shape. Nevertheless, these results were limited to only a few quality of life issues and were inconsistent in relation to specific pulse shapes. Conclusion : If we have more samples and better methods for collecting data, we will have better results, allowing us to improve our ability to predict and treat hypertension.

Background: Eosinophilia is well recognized in specific conditions. The objective of the present study was to determine clinico-radiologic characteristics of eosinophilia and changes in prevalence over 10 years in recipients of private health screening program at a tertiary hospital in Korea. Methods: Data of private health screening program recipients at the health promotion center of Chung-Ang University Hospital from 2004 to 2013 were collected. Health-related questionnaires and laboratory findings of private health screening program with possible relation with eosinophilia were reviewed. Results of enzyme-linked immunosorbent assay (ELISA) for parasite, chest computed tomography, and pulmonary function test were also reviewed. Results: The cumulative prevalence of eosinophilia was 4.0% (1,963 of 48,928). Prevalence of eosinophilia showed a decreased trend from 2004 to 2013. Most cases (96.6%) had mild degree of eosinophilia. Eosinophilic subjects were older and male-predominant. They showed lower levels of forced expiratory volume in 1 second ($FEV_1%$), forced vital capacity (FVC%), and $FEV_1/FVC$ than those without eosinophilia. Eosinophilic subjects showed higher positive rate for common parasite in ELISA than those without eosinophilia. On radiologic findings, consolidation and ground glass opacities were positively associated with the degree of eosinophilia. When eosinophil was classified based on severity, statistically significant correlation between the severity of eosinophil and radiologic abnormalities was found. Conclusion: Eosinophilia is uncommon in healthy population. It usually occurs at a mild degree. Eosinophilic patients have more radiologic abnormalities compared to those without eosinophilia. Such radiologic abnormalities are associated with the severity of eosinophilia.

홍삼(紅參)에서 내공발생(內空發生)은 품질저해요인(品質沮害要因)으로서 큰 비중을 자지하고 있다. 내공발생(內空發生)의 원인을 구명하고자 전국 주요산지의 재배환경 조건과, 그 산지에서 생산한 수삼(水蔘)을 각 포장별로 홍삼제조후 내공발생율(內空發生率)을 6개년간 조사하여 그 관계를 해석하고 여기서 얻은 주 요인들을 확인코자 몇개의 포장시험을 수행하여 확인한 결과를 요약하면 다음과 같다. 1. 홍삼에서 내공발생은 약 70%가 인삼동체의 주피부와 중심부 경계면에서 발현하므로 수삼의 주피부와 중심부간의 소질 차이에서 시인되는 것으로 보인다. 2. 홍삼에서 내공발생률이 27.5% 이상일 때는 천지삼율 저하와 밀접한 관계에 있지만 그 이하로 적게 발생할 때는 내공외의 다른 요인이 크게 작용하는 것으로 보였다. 3. 광(光)이 많이 들어가는 해가림구조(전후주고(前後柱高), 전후주(前後柱) 및 해가림 폭(幅)/후주고(後柱高) 비(比)가 큼)에서 내공발생율(內空發生率)이 높은 경향이나 유의성은 없었으며, 투광율(透光率) 15.9% 까지는 내공발생(內空發生)이 줄어들다가 그 이상으로 높아지면 다시 증가하였다. 4. 토양수분(土壤水分)과 내공발생율(內空發生率)과의 관계는 내공발생율(內空發生率)이 27.5% 이상으로 심할때는 부상관(負相關)이고 그 이하에서는 정상관(正相關)을 보여, 토양수분은 내공발생이 많을 때에는 내공(內空)요인으로 크게 기여하는 것으로 보이며, 토양공극율(土壤孔隙率)도 같은 경향이었다.
