趙鮮雄 全北大學校 1980 論文集 Vol.22 No.-

The author has attempted in the treatise an empirical analyses of the effect of trade-biases and the factor of international competitive strength. By virtue of both measurement and comparative method those factors of the effects of priceand output, the trade-biassed, productivity growth and elasticity of substitution for export which are relevant to Korea export expansion have been investigated, in contradistinction to those of certain developed countries. In order to attain the purpose of the study the following coefficients have, in the main bee calculated on the part of Korea and nine developed countries of market economies during the period of 1963 through 1975 : a) The price elasticity of export supply b) The price and output elasticity of export demand; c) The relation of export share to labour productivity and per capita wage; d) The effect of export and import-biassed pattern; e) The elasticity of substitution for export and import; And, the statistical analyses are based on the regression equation, and the coefficients are computerized. From the coefficients thus measured, the findings are summarized in the followings; 1. The effects of price and output on export; a) The price elasticity of export supply in Korea is on the highest tide of the measured countries. On the other hand, the price elasticity of export demand illustrates the remarkably low coefficients. The effect of price, therefore, exerts a ruling influence on the export supply of Korea, and it is found that the effect of output has conspicuously functioned than the effect of price. b) In the cases of U.S,A and Japan the non-price competitive factor has functioned powerfully; on the other hand, the price competitive factor in Korea has played an important role. c) The distribution ratio to labour on gross value added in Korea, compared with that of the developed countries, illustrates a very low level. 2. The growth of productivity and the effect of the trade-biased; a) The trade-biassed caused by the growth of productivity shows that the effect of the import-biased has been realized in Korea. The fact that the growth of productivity is biassed to the import substitution industry has been indicated. b) In the view-point of the powerful influence of the output elasticity on the export demand, the growth of productivity on the part of heavy manufacturing industries should be rapidly realized. 3. The elasticity of substitution for export by total industry based on the world; a) The elasticity of substitution for export in Korea has been shown most high. This means that the effect of price has contributed to increase of export in Korea more than the effect of output and other non-price factors. b) Among the developed countries, the elasticity of substitution for export in Japan is the highest. Italy the second, Germany the third, and U.S.A., the fourth. On the other hands, a particularity can be seen in some developed countries like Canada, Norway, Sweden, and Denmark. In a word, their elasticity of substitution for export is no significant. It is considered that the effect of price has not played an important role in export. c) The elasticity of substitution for export in Korea based on the measured countries has not been stable, which means there has been very little effect of substitution for export between Korea and the developed countries, if there be any. 4. The elasticity of substitution for export by sectoral industry; a) In Korea, chemicals is most elastic, light industry goods the second, food and beverage the third and raw materials excluding fuels is the fourth. It is presumed that the competitive strength of price has strongly worked in above mentioned industries. b) In the case of the measured countries, U.S.A. is very elastic in the field of food & beverage and raw materials. Germany in the field of food & beverage, raw materials, light industry goods and machinery & equipment of transportation. In Sweden, raw materials, food & beverage, chemicals and machinery & equipment of transportation are very elastic. On the other hand, light industry goods, machinery & equipment of transportation and raw materials are elastic in Denmark. In Japan, machinery & equipment of transportation, raw materials, chemicals and light industry goods are elastic. Contrary to this, the effect of price has been found to be very little significance in Italy and United Kingdom. 5. The elasticity of substitution for export based on the measured countries; a) Presuming the measured results of the elasticity of substitution for export in sectoral industry of Korea based on the measured countries, food & beverage has been elastic for that of U.S.A., materials for that of Germany, chemicals for that of U.S.A. machinery & equipment of transportation for that of Germany, light industry goods for that of U.S.A. b) Presuming international competitive strength in sectoral export industry of Korea on the base of the price competitive strength, machinery & equipment of transportation has been most strong, and chemicals the second, light industry goods the third, food & beverage the fourth, and the competitive strength of materials has been most weak. From these findings above mentioned, the author proposes the following recommendations if Korea's export competition strength is to be reinforced: 1. The economic adaptability of the industrial structure, which Prof. D. P. Kindleberger has exerted, should be strengthened with consideration of the price mechanism which would cause the factor of trade expansion among the developed countries. 2. In order to maintain the continuous growth of export, the dynamic comparative advantage should be strengthened by means of the technological progress and the expansion of R & D expense argued by Messrs. D. B. Keesing. W. Gruber. D. Mehta and R. Vernon.

연구목적 : 본 연구의 목적은 광주광역시의 도시 및 농촌 지역에 거주하는 노인에서 치매의 유병률과 위험인자를 조사하고자 하였다. 부가적으로 이 두 지역간에 치매의 유병률과 위험인자를 비교하고자 하였다. 방 법 : 광주광역시의 전형적인 도시와 농촌지역의 65세 이상의 노인(N=1,598)을 대상으로, 2단계의 역학연구를 수행하였다. 1차 선별 단계에서는 38명의 훈련된 연구보조원이 대상노인을 면담하여, 사회인구학적 특징을 조사하고 한국판 간이정신상태검사(Korean version of Mini-Mental State Examination ; MMSE-K)로 평가하였다. 2차 임상 진단 단계에서는 1차 단계에서 MMSE-K 점수가 24점 이하인 노인(N=431)을 대상으로, 전문연구팀의 임상적 평가를 통해 치매를 진단하고 원인질환별로 알쯔하이머병(Alzheimer's disease ; AD), 혈관성 치매(vascular dementia ; VaD) 및 기타 치매로 분류하였다. 대상노인에서 치매의 유병률을 측정한 후, 광주광역시 전체 노인의 연령보정 유병률을 산출하였다. 전체 대상에서 AD의 위험인자를 조사한 후, 도시와 농촌군으로 나누어 분석을 다시 시행하였다. 결 과 : 1차 및 2차 단계의 참가율은 각각 71.0%(N=1,134) 및 83.2%(N=410) 였다. 연구 참여 노인(N=1,134)에서 전체 치매, AD 및 VaD의 유병률은 최소 각각 9.7%, 5.2%, 1.8%였다. 광주광역시 전체 노인의 연령 보정 유병률은 각각 10.7%, 5.7%, 1.9%인 것으로 산출되었다. AD의 독립 위험인자는 고령, 여성, 무학이었다. 도시와 농촌에 따른 유병률의 차이는 파악되지 않았다. 그러나 AD의 위험인자는 지역에 따라 차이가 있었다. 도시 노인에게는 무학만이, 농촌 노인에게는 고령과 여성인 경우가 독립 위험인자였다. 결 론 : 광주광역시 노인에서 치매의 유병률은 높았고, 이는 국내 다른 지역에서 수행된 선행연구 결과와 유사하였다. 알쯔하이머형 치매의 위험인자는 도시와 농촌에 따라 다른 결과를 보였다. 본 연구 결과는 한국에서의 치매의 실태를 반영하며, 치매의 적절한 관리와 예방을 위해서는 지역성 특성이 고려되어야 함을 시사한다. Objectives : The purpose of this study was to investigate the prevalence rate and risk factors of dementia in an urban and a rural sample of older persons in the metropolitan Kwangju area, Republic of Korea. In addition, the prevalence rate and risk factors of dementia between the two samples were compared. Methods : A two-phase epidemiological study of residents aged 65 or over(N=1,598) was conducted in a highly developed, urban and a non-contiguous, poorly developed, rural area of metropolitan Kwangju. In the first(screening) phase, 38 trained research assistants collectively peformed in-home interviews for all participants. Detailed sociodemographic characteristics were gathered and the Korean version of Mini-Mental State Examination (MMSE-K) was administered. In the second (diagnosing) phase, diagnosis of dementia was established for those scoring 24 or less on the MMSE-K in the screening phase(N=431), and etiological types of dementia were classified to Alzheimer's disease(AD), vascular dementia(VaD) or miscellanous type by two teams of experts. Prevalence rate of dementia was determined in the participants, and age-standardized prevalence rate adjusted by age distribution in metropolitan Kwangju was estimated. For AD, the risk factors were investigated in all participants, and analyses were repeated for the urban and rural samples separately. Results : The participating rates in the first and second phases were 71.0%(N=1,134) and 83.2%(N=410), respectively. In the participants, the prevalence rates of dementia(all types), AD and VaD were 9.7%, 5.2% and 1.8%, respectively. The age-standardized prevalence rates were 10.7%, 5.7% and 1.9%, respectively. Aging, female gender and no education(complete lack of formal education) were identified as independent risk factors for AD. No difference between the urban and rural samples was observed in the prevalence rates of dementia(all types), AD and YaD. However, risk factors for AD differed between these areas. In the urban sample, no education was the only significant factor ; whereas, aging and female gender were identified as risk factors in the rural sample. Conclusion : A high prevalence rate of dementia was observed among old persons in metropolitan Kwangju, consistent with previous studies conducted in other Korean areas. The risk factor profi1es for AD differed between urban and rural settings. The results of this study reflect the current status of dementia in Korea and suggests that appropriate management and prevention strategies for dementia should be tailored toward the geographic settings.

섬유강화 플라스틱 복합재의 성형공정에 관한 연구 : 일방향 섬유강화 복합재의 점도측정 및 유동해석 Flow analysis and Measurement of viscosity of Unidirectional Fiber Reinforced Plastic Composites

조선형,안종윤,이국웅,윤성운 한국공작기계학회 2001 한국생산제조학회지 Vol.10 No.2

During a compression molding process of Unidirectional Fiber Reinforced Thermoplastic Composites, control of filling patterns in mold and distribution of fiber is needed to predict the effects of molding parameters on the flow characteristics. To obtain an excellent product and decide optimum molding conditions, it is important to know the relationship between molding conditions and viscosity. In this study, the anisotropic viscosity of the Unidirectional Fiber-Reinforced Polymeric Composites is measured by using the parallel plastometer. The model for flow state has been simulated by using the viscosity. The composites is treated as an incompressible New-tonian fluid. The effects of longitudinal transverse viscosity ratio A and slip parameter α on buldging phenomenon and mold filling patterns, are also discussed.

Objectives : This study aimed to investigate the prospective associations of premenstrual dysphoric disorder (PMDD) with quality of life, socio-occupational function and disability. Methods : 170 nurses were recruited 6om two general hospitals. Interviews were made at baseline and at four follow-up points (two mid follicular phases and two late luteal phases ofthe two consecutive menstrual cycles). The baseline evaluation Consis-ted of sociodemographic characteristics and menstmal history. PMDD was diagnosed by DSM-IV criteria after observation of the two menstrual cycles. The follow-up evaluations were consisted ofthe World Health Organization Quality of Life-Brief form, the Social and Occupational Functioning Assessment Scale, and the World Health Organization Disability Assessment Scale-II. Results : PMDD was detected 15 (8.8%) of 170 participants. The PMDD group showed significantly worse quality of life and socio-occupational functioning than the none-PMDD group particularly at the late luteal phases. No significant differences were found in sociodemographic characteristics and menstrual history between those with and without PMDD. Conclusion : PMDD was prospectively associated with worse quality of life and socio-occupational functioning in this study group.

經濟統合에 따른 貿易擴大效果의 實證的 硏究 : EC를 中心으로 focusing the EC

趙鮮雄,金重根 全北大學校 1996 論文集 Vol.42 No.-

The purpose of this study is to empirically examine economic integration and trade expansion effects focusing the EC. We estimate to see the level and time trend in the EC economic integration using the gravity model with yearly data from 1970 to 1994. The main result of the study is that the trend of empirical effects is similar to that of EC's actual trade flow in year and economic integration stage separately. Though the trade expansion effects are increased slightly in the fourth stage('86-'92) and fifth stage('93-'94) due to the Single European Act, the Completing the Internal Market did not contribute to largely increased intratrade in EC because of recession in the EC economy. In the standpoint of increased intra-trade in EC, these result suggest to be proceeded to recover in the EC economy.

장섬유강화 고분자 복합판의 프레스 성형에 있어서 니트라인에 관한 연구

조선형,이국웅,안종윤,윤성운 한국공작기계학회 2001 한국생산제조학회지 Vol.10 No.2

In recent years, compression molding of lone fiber-reinforced thermoplastics has been increased in commercial aspects. In the process of compression molding of composites, the flow analysis must he developed in order to accurately predict the finished part properties as a function of the molding process parameters. In this model FRTP is assumed to be nonisothermal fluid, which has different viscosities in extensional and in shear. For verification of the model, the formation of a knit line in the L-shaped parts is compared with that of experiments results. In this paper we will discuss the effects of extensional & shears viscosity ratio ξ and slip parameter α on the other mold fill-ing parameters

박진균,김지웅,기선완,신의진 大韓神經精神醫學會 2004 신경정신의학 Vol.43 No.4

Objectives : The purpose of this study was to evaluate the reliability and validity of the Korean version of Preschool Temperament and Character Inventory (K-psTCI), a questionnaire based on Cloninger's seven-factor model of personality. Methods : The psTCI was translated into Korean and administered to 266 children aged 2-6 years. α test-retest study of the K-psTCI was conducted across a 4-month interval, Internal consistency was calculated by Cronbach a. Test-retest and reliability was analyzed by Pearson correlation analysis. Factor analyses for the temperament and character dimensions were performed using principal component analysis, rotating factors by varimax. The psTCI scores of Korean and United States preschoolers were compared Results : Cronbach α values for the K-psTCI scales ranged from .62 to .78 for each dimensions. Test-retest correlations (r) ranged from .50 to .77 for each dimensions. Explorative factor analysis with the condition of eigenvalue greater than 2 produced four factors for the temperament items and three factors for the character items like the US original version of psTCI. Through factor analyses, five items in the K-psTCI were categorized differently from the US version of psTCI. Korean preschoolers had higher mean scores on Cooperativeness (CO) in males as compared to a sample of US preschoolers. Conclusion : The results of this study suggests that the Korean preschool TCI is satisfactory in reliability and validity.

This study was performed to predict some aspects of tidal currents and pollutant dispersion according to the facilities for seawater exchange in order to improve the water quality in Daeheuksando. A numerical simulation was executed, using the hydrodynamic module and advection dispersion module in MIKE 21 program. As a result of hydrodynamic simulation, it did not show change greatly in all cases. But, cutting part of Jungang-breakwater increased greatly than other area. When cut inside part in Jungang-breakwater, pollutant density of Yeri area decreased greatly by the ratio of 0.40 as compared with other cases. Also, dispersion extent diffused whole area of inside sea area of Daeheuksando. This case is the most effective for seawater exchange inside sea area of Jungang-breakwater.
