  • The purpose of this study is to explore the relationships between hope, health locus of control and general health of nursing students. The subjects of this study were 161 female students of National Nursing School in Seoul. Data was collected through a questionnaire from May 11 to May 23, 1998. The tools used for this study were Hope scale developed by Miller and Power, Multidimensional Health Locus of Control Scale developed by Wallston and Wallston and General Health Scale(Modified Conel Medical Index) developed by Nam Ho Chang. Data were analysed in an the $SPSS/pc^+$ program using frequency for the demographic characteristics, 1-test and ANOVA for relationship between the variables and demographic characteristics and for it's differences of hope and general health control. Peason correlation coefficient for relationship between the 3 variables, hope, health locus of control, and general health. The results of this study were as follows ; The 1st hypothesis : that 'Between hope, health locus of control (HLC) and general health of nursing students will have positive relationship', was supported(=.2883, p=.000). The 2nd hypothesis; that 'The hope score of nursing students in HLC-internal group will be higher than others' was supported(F=5.22, p=.0063). The 3rd hypothesis ; that 'The general health of nursing students in HLC -internal group will be higher than others' was accepted(F=2.94, p=.0554). The 4th hypothesis ; that 'Hope, HLC and general health of nursing students according to demographic characteristics will be different ' was accepted in part. o In hope the more age, the higher score. o In HLC the group of non religious have higher score(t=-2.02, p=.045). o No experienced addmission was revealed HLC-internal group(t=-1.91, p=.058). o Non religious group has a tendency to dependent upon on powerful other person(t=-1.99, p=.049). o The hope score of nursing students was very high(4.49/6point). o The general health status of nursing students was vert good(92.88/114point). o Most of nursing students was in HLC-internal group(81.4%). o The most frequent complaints of nursing students was dizziness suddenly developed(68.4/114point), very nervous in small thing(67.83/114) and very nervous to others critics(68.4/114) in turn. In conclusion, the students who have high score of hope, in HLC-internal group have good general health. Hope inspiring not only makes one's good health but also makes others good health and powering hope. For good health person who are in HLC-internal group have powerful hope, keeping good health would be a good stretegy to change the student's HLC and make them good health and hope powering then it would be a good method to change the HLC to HLC-internal group.

  • 본 연구는 기업의 내부역량(Internal Capability)과 외부지식(External knowledge)을 통해 기업의 동태적 역량을 측정할 수 있으며, 동태적 역량이라는 틀에서 보면 기업의 행위를 진화적 관점의 적합도(Fitness)와 렌트(Rent)로 설명할 수 있다는 점에서 착안하고 있다. 본 연구의 목적은 동태적 역량을 기반으로 나노기술 기업의 유형분류 및 분석 모델을 제시하고자함이며, 이를 위해 나노기술 분야와 관련된 제품생산 활동을 하고 있는 국내 359개 기업에 대한 설문조사를 바탕으로 기업의 유형을 어떻게 분류하고, 성과를 측정하게 되는지를 실증적으로 분석하고 있다. 기업의 내부역량(Internal Capability)과 외부지식(External knowledge)이 기업의 성과에 영향을 주는가를 분석하였다. 또한 실증분석 결과를 바탕으로 내부역량과 외부지식을 나타내는 4개 변수들을 주성분 분석(Principal Component Analysis)하여 2개의 새로운 변수들을 도출하였다. 내부역량과 외부지식의 상대적 정도를 기준으로 4개의 기업군을 분류하고, 유형별 재무적 성과를 비교한 결과 내부역량과 외부지식이 높은 기업이 낮은 기업보다 평균적으로 재무적 성과가 높은 것으로 나타났다. 기술수준 분석의 결과도 내부역량과 외부지식 수준이 높은 기업이 상대적으로 높은 기술수준을 보였다. 그러나 4가지 유형의 재무적 성과차이를 분석한 결과는 기술적 적합도와 진화적 적합도의 상호작용에 의해 재무적 성과가 결정될 수 있음을 보여주고 있다.

  • 본 논문은 과연 법인의 전기 유보금이 당기 투자 및 배당에 유의한 영향을 미치는지를 업종별 더미변수를 통하여 살펴보고자 한다. 본 논문의 연구결과 양 년도에 걸쳐 물적 투자에서는 제조업, 기술서비스업, 도소매업, 정보서비스업, 건설업, 운수업종에서 전기 유보금이 당기 물적 투자에 유의한 영향을 미쳤으며, 이 중 개발비 및 경상개발비에 대한 투자보다는 유형자산에 대한 투자가 더 효과적인 것으로 나타났다. 인적 투자에서는 제조업, 기술서비스업, 정보서비스업, 운수업종에서 전기 유보금이 당기 인적 투자에 유의한 영향을 미쳤으며, 이 중 급여에 대한 투자보다는 교육훈련비 및 복리후생비에 대한 투자가 더 효과적인 것으로 나타났다. 배당에서는 제조업, 도소매업, 정보서비스업, 운수업, 기타 업종에서 전기 유보금이 당기 배당금에 유의한 영향을 미쳤으며, 이 중 배당률에 대한 지출보다는 배당금에 대한 지출이 더 효과적인 것으로 나타났다. 본 논문의 공헌점은 전기 유보금이 당기 투자 및 배당에 유의한 영향을 미치는지를 업종별로 구분하여 그 효과를 실증분석 하였다는 점이다. 이에 반해 본 논문의 한계점으로는 정확한 세무자료의 수집이 현실적으로 어려워 회귀분석 결과 나온 계량 적인 결과물들이 과연 정부의 정책 효과를 어느 정도 정확히 반영하고 있는지 그 기준을 찾는 연구가 필요하리라 생각된다. 이와 더불어 국내외 경제 및 경영 환경의 모호성과 불확실성에 대해 정부가 어떤 정책을 추진해야 기업이 안심하고 투자할 수 있는지 그 연구도 필요하리라 여겨진다.

  • A simplified statistical methodology is developed in order to both reduce over-conservatism of deterministic methodologies employed for PWR fuel rod internal pressure (RIP) calculation and simplify the complicated calculation procedure of the widely used statistical methodology which employs the response surface method and Monte Carlo simulation. The simplified statistical methodology employs the system moment method with a deterministic approach in determining the maximum variance of RIP The maximum RIP variance is determined with the square sum of each maximum value of a mean RIP value times a RIP sensitivity factor for all input variables considered. This approach makes this simplified statistical methodology much more efficient in the routine reload core design analysis since it eliminates the numerous calculations required for the power history-dependent RIP variance determination. This simplified statistical methodology is shown to be more conservative in generating RIP distribution than the widely used statistical methodology. Comparison of the significances of each input variable to RIP indicates that fission gas release model is the most significant input variable.

  • In recent years, hydroforming technology has been one of the most important technology in automotive industry in the points of weight saving, cost reduction and qualify improvement. However, compared with traditional metal forming technology, hydroforming has much fewer information in experience and empirical knowledge. But we don't have my sufficient time and money to produce hydroforming products using real blank directly Therefore Simulation is essential in hydrofonrung technology development. In this paper, we simulate the side member as the tubular hydroforming technology. The manufacturing process of side member' consists of pre_bending, pre_forming, and hydroforming of a thin tube. Variables such as internal pressure, end feeding, and tool geometry are optimized to improve the forming safety. And we simulate side member according to several lubricant conditions. from those simulations, we find that strain distributions can be reduced well by internal pressure and end feeding control, and lubrication is the most important thing in hydroforming process.

  • A numerical model for masonry is proposed by following an internal variable approach originally developed in the field of elastic-plastic analysis. The general features of the theoretical framework are discussed by focussing on finite element models applicable to incremental elastic-plastic problems. An extremum property is derived and its implications in terms of convergence for convenient algorithms are briefly discussed, by including the case of softening materials and damage effects. Next, a numerical model is presented, which is suitable for masonry, can be developed according to the same internal variable formulation and enjoys similar properties. Some numerical results are presented and compared with the response of a masonry shear wall subjected to pseudodynamic tests.

  • Exact dynamic stiffness model for a uniform straight pipeline conveying unsteady fluid is formulated from a set of fully coupled pipe-dynamic equations of motion, in which the fluid pressure and velocity of internal flow as well as the transverse and axial displacements of the pipeline are all treated as dependent variables. The accuracy of the dynamic stiffness model formulated herein is first verified by comparing its solutions with those obtained by the conventional finite element model. The spectral element analysis based on the present dynamic stiffness model is then conducted to investigate the effects of fluid parameters on the dynamics and stability of an example pipeline problem.
