혈중 지질농도는 식이단백질 종류보다는 연령의 영향을 많이 받아, young군보다 old군의 총 콜레스테롤, TG, HDL-콜레스테롤, LDL+VLDL-콜레스테롤 및 AI 모두 높았다. 한편 콩 단백질군에서 HDL-콜레스테롤 수준이 증가하고, LDL+VLDL-콜레스테롤와 AI는 감소하여, 심혈관질환에 대한 콩 단백질의 유익한 효과를 확인할 수 있었다. 식이단백질에 의해 유의한 영향을 받은 혈장 인지질의 지방산조성중 22:0, 18:1ω9, ∑MUFA 조성은 카제인군에서 콩 단백질군 보다 높았으며, 반대로 ∑SFA 조성은 카제인군에서 낮았다. 연령에 의해 혈장 인지질 지방산 조성에 있어 유의한 차이를 보인 지방산 중 22:0, 18:1ω9, 22:1, 18:3ω3 및 22:4ω6는 young군에서 높은 반면에, 22:6ω3, ∑ω3, 18:2ω6, 20:4ω6, ∑ω6 및 ∑PUFA의 조성비율은 old군에서 높게 나타났다. 이와 같이 식이 단백질의 종류보다 연령의 영향력이 더 많이 나타난 것은 혈중 콜레스테롤 수준이 식이 단백질보다는 연령의 영향을 더 크게 받았기 때문으로 생각된다. 혈장 인지질 지방산의 대사지표 중 Δ7-desaturation index(16:0⇒16:1ω7)와 Δ9-desaturation index(18:0⇒18:1ω9)가 식이 단백질의 영향을 받아 카제인군에 비해 콩 단백질군에서 유의하게 낮았다. Δ7- 및 Δ9-desaturation index만이 식이 단백질의 영향을 받은 것은 식이 단백질보다 desaturase 활성에 더 큰 영향력을 미치는 콜레스테롤이 식이에 첨가되었기 때문이라 생각된다. Δ-4 desaturation index (22:4ω6⇒22:5ω6)는 young군에 비해 old군에서 높았으며, elongation index(20:4 ω6⇒22:4ω6)는 old군에서 낮았다. 대부분의 elongation과 desaturation 단계는 연령에 따라 유의한 차이를 보이지 못하였으나, ω3계 지방산의 전체적인 elongation-desaturation 단계를 나타내는 ∑products-fatty acid(ω3)/α-LNA(ω3) 비율이 old군에서 young군보다 유의하게 높아, 연령에 따른 PUFA 대사의 변화가 관찰되었다. 이상에서와 같이, 콩 단백질의 섭취로 흰쥐 혈장 인지질의 ∑MUFA 조성은 낮고 ∑SFA 조성은 높아 다른 지질 강화성분의 섭취와 유사한 결과를 나타내었다. 혈중 콜레스테롤 수준이 높은 old군에서 체내 막조직의 유동성을 유지하기 위해 PUFA의 합성 특히 ω3계 지방산의 elongation-desaturation이 증가하여 총 PUFA 조성이 young군보다 높았다. 연구결과로 이소플라본을 포함한 콩 단백질의 혈중 지질저하 기전에 대해 체계적인 설명은할 수 없지만, 콩 단백질이 혈장 지방산의 조성을 변화시킴으로써 간접적으로 심혈관계 질환에 대해 유익한 효과를 미침을 알 수 있었다. 한편, 이러한 혈관의 건강과 관련된 콩의 유익한 효과는 이소플라본과 같은 콩의 특정 성분의 단독효과라기보다는 콩 단백질과의 복합효과에 의한 것이라는 주장은 매우 설득력 있다고 생각된다. Effects of soy protein concentrate (SPC) containing isoflavone and casein diets on plasma phospholipid (PLs)-fatty acid patterns were investigated in 7- & 40- wk old female rats. Diets containing 16% SPC (soy/young: SY, soy/old: SO) and casein (casein/young: CY, casein/ old: CO) supplemented with 0.5% cholesterol were fed for 4 wks. Fatty acid compositions of plasma PLs were determined by TLC and GLC. Compared to the dietary protein effects, age effects on serum lipids were more profound. The levels of total cholesterol (Chol.), triglyceride, HDL-Chol., (LDL+VLDL)-Chol. and atherogenic index (AI) were higher in older groups (OC & OS) than younger groups (YC & YS). Soy groups had higher HDL-Chol. level and lower (LDL+VLDL)-Chol. and AI, compared with casein groups. The compositions of C22:0, C18:1ω9 and sum of MUFA in plasma PLs were significantly higher in casein group (CY & CO) than soy group (SY & SO), but those of sum of SFA were higher in soy group. The compositions of C22:0, C18:1ω9, C22:1, C18:3ω3 and C22:4ω6 were higher and those of C22:6ω3, sum ofω3, C18:2ω6 C20:4ω6, sum ofω6 and sum of PUFA were lower in plasma PLs of younger rats. The average P/S and ω3/ω6 ratio in older group was higher. The Δ-7 desaturation index (16:0⇒16:1ω7) and Δ-9 desaturation index (18:0⇒18 : 1ω9) were lower in soy group than casein group, while Δ-6 and Δ-5 desaturation index were not affected by dietary protein. The Δ-4 desaturation index (22:4ω6⇒22:5ω6) were higher and, elongation index (20:4ω6⇒22:4ω6) were lower in older group. The ratio of the products of ω3 fatty acid series/precursor of ω3 fatty acid series (C18:3) was significantly higher in older group, which in- dicated that age affected the plasma PUFA metabolism. On the other hand, older rats had higher serum cholesterol level compared with younger rats. Taken together, these changes in fatty acid composition might cause minimal changes in the membrane fluidity induced by the increase serum cholesterol level.

The purpose of this investigation was to see whether preschoolers(children of 3, 4, and 5 years of age) understand the fundamental ontological distinction between the internal mental world and objective physical reality. Real physical objects can be distinguished from mental entities on the basis of three criteria. (1) Behavioral-sensory evidence → whether the entity can be seen, touched, and physically acted upon. (2) Public existence→ whether other persons experience the entity. (3) Consistent existence→ whether the entity consistently exists over time. In consistent with previous research findings which tested Western children, the results demonstrated that even 3-year-olds were able to judge real and mental entities appropriately on the basis of the three criteria. The findings are discussed briefly in relation to the Piaget's characterization of young children as realists and recent researches on children's understanding of the mind.

GASKET LIFE CRITERIA AT LOW TEMPERATURES ADOPTING PROPORTIONAL COMPENSATION FOR LOSS OF FLEXIBILITY AND CONFORMABILITY

Young-Doo Kwon,Seong-Hwa Jun,Jin-Sik Han,Dong-Jin Lee 한국자동차공학회 2018 International journal of automotive technology Vol.19 No.1

In the automobile industry, the service life of gaskets is defined as the time until which a released gasket recovers 60 % of the original compression. It was observed that the recovery curves of gaskets were highly nonlinear at high temperatures, and relatively nonlinear at temperatures above the room temperature. However, it was also noted that the recovery curves of the gaskets at temperatures below room temperature exhibited linearity with respect to the ln(time). Automotive manufacturers demand gasket life criteria that exceed a specific time or the entire life of a car. In the case of gaskets used at lower temperatures, since materials encounter losses in its flexibility and conformability, the definition of service life specifying a 60 % recovery may not be sufficiently safe to eliminate possible leakages. In this study, new gasket life criteria that could be used at low temperatures were proposed. The new criteria were proposed based on the change in Young’s modulus of the gasket material in order to conserve the sealing capability.

創造派 硏究 : Centering on the influence of modern Japanese Literature 日本 近代文學의 影響을 중심으로

金永和 제주대학교 1990 논문집 Vol.31 No.1

Kim Dong-In, Chun Young-Taek and Choo Yo-Han of the 'Changjo Group' Who let the modern literature set root of this country have all studied abroad in Japan in 1910s. Learning new knowledge in Tokyo, Japan, from boyhood until youth age, they were baptized with the modern Japanese culture which had been pursuing toward westernization since Meiji-Innovation. Their pursuit of literature was achieved under these conditions and surroundings, and the literary works which they had mainly read were modern Japanese Literature and Western Literature translated into Japanese Language. Those literary works they read during the period of literary apprenticeship have influenced on their literary works in a way or another. Accordingly, this means that the literature of the'Changjo Group' has been influenced by Japanese as well as Western Literature. Those influences are noticed especially in the following exapmles: Firstly, by anlayzing elaborately "Baetaragi" (1921) of Kim Dong-In, we can find, that the point of view and plot is quite similar to that of "Unmeironsha" (1902) of Kunikita Topbo. This means that the technique of novel-writing of Kunikita has had influence on that of Kim Dong-In. Secondly, if we analyze "Idiot or Jenius"(1919) of Chun Young-taek, we know that the setting of character, tile processing of plot and the point of view etc, are very similar to "Spring Bird, Harunotori"(1904) of Kunikita. This again means that Chun Young-Taek was unconsciously influenced by Kunikita during reading his novels. Thirdly, the early day's poems of Choo Yo-Han such as "Fire Play, Bulnori" show resemblance of French Poems translated into Japanese, in its rhythm, setting of talker etc. This shows that Choo Yo-Han learned the techniques of it engaging in favorite reading of French poems in Japanese, which denotes his receiving of a kind of influence In the early days of the literature of the 'Changjo Group', the influence of modern Japanese literature was remarkable. We are able to know that modern Japanese Literature since Meiji-Innovation has greatly influenced the formation of modern Korean Literature if we consider that the 'Changjo Group' of Korean Literature has contributed to set its root of modern literature in this country.

分斷狀況과 文學的 形象化 : 吳永壽의 「머루」에서 「幻想의 石像」까지 in the cast of Oh Young-soo

金永和 제주대학교 1986 논문집 Vol.16 No.1

Oh Young-soo(1914-1979) saw a tragic situation of country's division together with country's liberation at the age of 32. Soon after this, he experienced 6·25 war, and at this time he served in the front line with the other literary men. Around 1970, he also saw the question of reunion of families, which were scattered all over the South and North, being discussed through the Red Cross Mediation, and paid a concern a new on the South-North Subejects following the 7.4 Joint Statement. He wrote the novels, deeply feeling and utilizing as a foundation of his works the tragedy and pain of our people inflicted by the division of land during 35 years of his living in the age of division. Generally, such works can be classified and summorized as follows: 1) Such novels as "Wild Grapes", "Reminiscences" belong to this catergory, whcih are written on the life of common people who were sacrificing their lives sandwitched between Communist Guerrillas' activity and police force liquidating the guerrillas, with the period before 6·25 war for its background. 2) Such novels as "Two Refugees", "Frost Spring" also belong to this classification which are written on ruining of common peoples's livelihood itself, that is, the death and refugee life etc., with the background of 6·25 war. 3) There can be found those novels whcih reilluminate the meaning and the injury of that war and conceive positively of overcoming of country's division in the background of the beginning of 1960's which entered into the period of a little stability along with the end of the war. Such novels are "Anna's will", "Chupung Ridge" 4) The other novels are those which positively think of overcoming of the separated families' tragedy and of country's division with the background of 1970's in which a movement of scattered family reunion and 7.4 Joint Statement made an apperance. "Bird", "Stone Statue of Fantasy" belong to them. This writer embodied the above situations into literary works, examining how the situation of the division gave pains our people and searching the ways for its overcoming. This means that the writer wrote the novels cherishing deep interest in the past history and prest realities.

Objective: This study was performed to examine the relationship between community-based social support and psychosocial distress in workers. Methods: The study subjects were 596 workers recruited from 11 companies in Chungju city. A structured questionnaire was used to assess sociodemographics, health-related behaviors, job characteristics, job stress, work-based social support, community-based social support and level of psychosocial distress. Results: Hierarchical multiple regression analysis showed that workers with no chronic disease, exercise and sufficient sleep had a higher score of psychosocial distress than those with chronic disease, no exercise, and not enough sleep. Coworker's work-based social support and community-based social support were negatively associated with psychosocial distress. The R square value of total independent variables on psychosocial distress was 0.409, and that of community-based social support on psychosocial distress was 0.052. Conclusion: This study showed that community-based social support served as a protective factor against psychosocial distress in some workers. We recommend the establishment of a worksite stress reduction program in occupational level as well as community-based social support.

The Relationship among Percieved Social Support, Hope and Quality of Life of Cancer Patients Tae, Young Sook. Kong, Eun Sil. Lee, Myung Hwa. Park, Geum Ja The purpose of this study was to investigate the relationship among percieved social support, hope and Quality of life of the cancer patients and to gain the baseline data for development of nursing intervention program for promoting quality of life in cancer patients. The design of this study was a cross sectional correlational survey. The subjects were 220 out and in-cancer patients in 5 general hospitals in Pusan The data were collected from July 2 to August 1,2001. The instruments were the Percieved social support scale(16 items, 5 point scale) had developed by Tae(1986), Hope scale(12 items, 4point scale) developed by Nowotny(1989) and Quality of life scale(31 items, 10 point scale) developed by Tae et. al(2000). The data was analyzed by the SPSS/PC+ program using frequency & percentage, item mean & standard deviation, t-test, ANOVA & Scheffe test, Pearson's correlation coefficient. The results of this study was as follows : 1) The item mean score of quality of life was 6.05±1.16 (range 0-10) .The heighest score of subarea of the quality of life was the spiritual wellbeing area (7.09±1.63) and the lowest score was social wellbeing area(5.53±1.65). The mean score of perceived social support was 52.65±10.32 (최고 1, 최저 80). The mean score of family support was32.71±6.66 (range 1- 40) and the mean score of medical team support was 19.93±5.95 (range 1- 40). The mean score of Hope was 37.02±5.64 (range 1-48). 2) There were statistically significant difference in the score of quality of life according to the life effect of religion (F=3.97, p=0.00), treatment method(F=2.94, p=0.01), area of diagnosis (F=3.48, p=0.01), stage of disease (F=13.74, p= 0.00). 3) There was significant correlation between perceived social support(r=0.44, p= 0.000 ; family support: r=0.334, p=0.000, medical support; r=0.395, p=0.000), hope(r=0.563, p= 0.000) and quality of life. In conclusion, there was a significant relationship among perceived social support, hope and quality of life. Therefore perceived social support, hope intervention programs should be developed to improve the quality of life in cancer patients.

1950년대 전반기의 문학

金永和 제주대학교 1992 논문집 Vol.34 No.1

This paper studies Korean Literature in the first half of the 1950s(from June 1950 through December 1954) from the viewpoint of the history of literature. The first half of the 1950s is the period deeply concerned with the Korean war, which began on June 25, 1950. Therefore, the Korean war is important sbuject matter in the literature of that time. This period selects war and refuge as its subjects, but it is mainly inspired by anti-communism in its themes. The works of this age are clearly characteristic of wartime literature and furthermore of anti-communist literature. For instance, there are anti-communist works, "Korean Soldiers Speak after Death," by Mo Yoon-sook, "Partizan," by Park Young-joon. Even though it was wartime, a literature of artistic quality consistently emerged. Among the outstanding works are a series of pure poems and novels written by Hwang Soon-won, Oh Young-soo and Kim Sung-han. Literature in the first half of the 1950s is a period of two co-existant types, wartime anticommunist literature and pure literature.

본 연구는 한국거래소 유가증권시장에 상장된 기업의 유형자산과 재고자산의 선택적 회계처리에 관한 실태 분석이다. 유형자산의 평가모형 및 감가상각방법 분석결과 유형자산의 평가모형 중 원가모형을 적용하고 있는 회사는 전체 728개 중 659개(90.5%), 64개(8.8%)가 원가모형과 재평가모형을 함께 적용하고 있다. 재평가모형을 적용하는 유형자산은 대부분 토지로 나타나고 있으며, 재평가모형만을 적용하는 회사는 없는 것으로 나타났다. 유형자산의 감가상각방법 중 정액법을 적용하고 있는 회사는 전체 728개 중 709개(97%), 정액법과 정률법을 함께 적용하는 회사는 11개(1.5%), 정액법과 생산량비례법을 함께 적용하는 회사는 2개, 정률법만 적용하는 회사는 1개 회사로 나타났다. 그리고 3개 회사는 유형자산 계정과목이 없으며, 2개 회사는 감가상각방법에 대한 내용이 주석에 공시되지 않고 있다. 재고자산의 수량결정방법과 가격결정방법을 분석한 결과 재고자산의 수량결정방법으로 계속 기록법과 실지재고조사법을 함께 적용하고 있는 회사는 728개 중 68개(9.3%), 실지재고조사법만 적용하는 회사는 3개, 계속기록법만 적용하는 회사는 1개 회사이다. 나머지 548개(75.3%) 회사는 주석에 수량결정방법을 공시하지 않고 있다. 재고자산의 가격결정방법은 회사들이 기업의 환경에 맞게 재고자산의 유형에 따라 다양하게 적용하고 있으며, 업종의 특성에 따라 금융업과 서비스업 중 지주회사에 해당하는 기업에서는 재고자산 계정과목이 재무상태표에 나타나지 않고 있으며, 유통업에서는 소매재고법(매출가격환원법)을 적용하는 회사가 9개 회사로 나타났다. 유형자산의 경우는 업종 특성에 관계없이 대부분의 회사가 평가모형으로 원가모형, 감가상각방법으로 정액법을 사용하고 있으며, 이와 달리 재고자산의 경우는 기업의 상황과 업종 특성을 반영하여 다양한 가격결정방법을 사용하고 있는 것으로 판단된다. This study is an analysis on the realities on the selective accounting of property, plant and equipment and inventories of listed firms in KOSPI. As a result of analyzing the evaluation model and depreciation method of property, plant and equipment, 659 firms(90.5%) out of the total 728 firms that applied cost model. and 64 firms(8.8%) applied cost model and revaluation model. Most of the property, plant and equipment applying the revaluation model are shown as land, and no firm applies the revaluation model. Among depreciation methods of property, plant and equipment, 706 firms(97%) of the total 728 firms that apply the straight-line method, 11 firms(1.5%) to apply the straight-line method and the fixed percentage method. There are two firms that apply the straight-line method and activity method, one firm that applies only the fixed percentage method. The three firms do not have a property, plant and equipment account and the two firms do not disclose depreciation methods in the footnotes. As a result of analyzing the method of determining the quantity of inventories and the method of determining the price, 68 firms(9.3%) of the 728 firms that applied perpetual inventory system and periodic inventory system. There are three firms that applies only periodic inventory system, and one firm that applies only perpetual inventory system. The remaining 548 firms(75.3%) do not disclose how to determine the amount in the financial statements footnotes. The method of determining the price of inventories varies according to the types of inventories according to the firm`s environment. According to the characteristics of the industry, firms in the financial and service industries that are holding companies do not show inventory account in their financial statements. In the retail industry, six firms apply the retail inventory method.

Two farmed young ostrich chicks were applied to pathology laboratory at Chungnam National University. Grossly, one ostrich showed rotated tibiotarsus, the other showed rolled toes. Case 1 ostrich was hypertrophy of fibualis longus and tibial cranialis tendon and gastrocnemius tendon in crus, inflammation of flexor digitorum longus. In histopathological views, myocytes of fiburalis longus were showed hypertrophy and hyperplasia. It is not found any specific feature in X-ray of the case 2 ostrich. Limb deformities were detected frequently in farmed ostrich chicks in 2- to 3 weeks old. Limb deformities were an important cause of mortality in farmed ostrich chicks during the first 10weeks after hatch. Cause of limb deformities were considered a nutrition problem.
