The purpose of this study was designed to develope and test the structural model that explains alcohol consumption behaviors among university students in Republic of Korea. The hypothetical model was constructed on the basis of the literature review and Pender's Health promotion model. Data was collected from questionnaires from 512 university students in Republic of Korea, from August to September, 2000. The reliability of instruments was adequate (Cronbach's alpha= .69-.90). Data analysis was done with SAS 6.12 for descriptive statistics and LISREL 8.13 program for covariance structural analysis. The results are as follows; 1. The overall fit of the hypothetical model to the data was moderate. Thus it was modified by male and female models. 2. The revised model has become parsimonious and had a better fit to the empirical data (male: χ2=87.21 p=.00, GFI=.97, AGFI= .94, NFI=.99, NNFI=1.0, CN=619.17, female: χ2=49.29 p=.31, GFI=.45, AGFI= .95, NFI=.99, NNFI=1.0, CN=370.02). 3. Self-efficacy was most significant factor and personality of novelty seeking, reward compensation, alcohol expectancy and drinking attitude have significant effects on male alcohol consumption behavior. 4. Personality of novelty seeking was most significant factor and personality of harm avoidance, friend influence, self-efficacies, alcohol expectancy and drinking attitude have significant effects on female alcohol consumption behavior.

The objective of this study is twofold: first, to investigate how organizations encourage factors that have an impact on employees' entrepreneurial behavior from employee's perspectives and experiences; and second, to discover how and why employees behave entrepreneurially within the organization. A case study method is considered as an appropriate approach to scrutinize intrapreneurial behavior because it principally concentrates on an investigation into a contemporary organizational phenomenon and context concerning entrepreneurial activities in-depth within its real situation. In data collection, an Asian multinational retail company was selected. Semi-structured interviews were carried out with 24 executive-level employees who had been working in various departments for more than 5 years. Each in-depth interview lasts for a duration of 40 to 60 minutes. The results reveal several understandings into the combination of individual-level and organizational-level factors that promote the intrapreneurial behavior and activities of the established firm in the context of Thailand. In this regard, six factors have been found as the key determinants that make an impact on innovativeness, proactiveness, and risk-taking behaviour of the employees. Those factors are personal preference, organizational stability, management support, compensation, reward system, teamwork, quality of relationship with colleagues, work autonomy and the quality of relationship with the superiors.

인식 가능한 피해자 효과(Identifiable victim effect)는 추상적인 피해자보다 인식 가능한 피해자에게 더 큰 동정심과 도움행위가 나타나는 현상을 말한다. 본 연구에서는 이 현상을 일반인들의 직관적인 법적 판단 상황에 적용해 피해자에 대한 인식이 제3자의 처벌 및 보상 판단에 미치는 영향을 검증하고자 했다. 그리고 이런 법적 판단에 대한 인식 가능한 피해자 효과를 통해 피해자의 실명과 신상을 전면에 내세워 여론의 관심과 지지를 얻어 관련 범죄의 처벌 강화를 목표로 하는 피해자형 설명법안의 효과를 설명하고자 하였다. 이를 위해 법적 판단에 필요한 법률적 요인을 배제한 교통사고 시나리오를 작성해 교통사고 피해자의 정보를 조작해 실험을 진행하였다. 실험1에서 참가자는 각 집단 별로 사고 피해자를 익명으로 제시한 조건(비인식 조건)과 이름, 나이 등의 신상정보를 함께 제시한 조건(인식 조건)을 읽고 배심원으로서 양형과 합의금을 판단하였다. 그 결과 피해자 신상정보의 유무는 제3자의 양형 및 합의금 판단에 영향을 미치지 않았지만, 세상의 공정성에 대한 믿음에 의한 조절효과가 나타났다. 즉, 피해자를 구체적으로 인식했을 때 세상이 공정하다고 믿을수록 더 높은 처벌과 보상을 원하는 것으로 나타났다. 실험2에서는 익명의 피해자(비인식 조건)와 성행 정보가 긍정적(긍정인식 조건)이거나 부정적인 피해자(부정인식 조건)를 비교해 피해자 특성이 가해자 처벌과 피해자 보상에 미치는 영향을 관찰하였다. 그 결과 피해자를 부정적인 사람이라고 인식했을 때 피해자가 누군지 알 수 없을 때보다 더 적은 보상 판단을 하는 것으로 나타났다. 또 부정적인 피해자 조건을 제외한 모든 조건에서 이전 판례의 평균보다 더 높은 가해자 처벌, 피해자 보상 판단을 하는 것으로 나타났다. 본 연구는 법률적 요인 외의 피해자 특성이 제3자의 법적 판단에 영향을 미친다는 것을 확인하였다. 나아가 법적 요인과는 무관하게 높은 처벌과 보상 판단을 피해자형 실명법안의 효과와 함께 해석하며 공정한 양형 기준 설정을 위한 사회적, 법적 논의와 후속 연구를 제안하였다.

High temperature deformation and softening behavior of SAF 2507 super duplex stainless steel (SDSS) has been investigated in connection with an FEM analysis of hot forging process. Flow curves at various strain rates and temperatures were determined first from compression tests, and the kinetics of dynamic recrystallization were also formulated through the analysis of load relaxation test results. Applying the dynamic materials and proposed by Prasad et al., it was possible to determine the characteristics of deformation behavior effectively at a given condition of deformation. Constitutive relations and recrystallization kinetics formulated from the test results were then implemented in a commercial FEM code. Flow stress compensation formulated upon the volume fraction of recrystallization and adiabatic heating was found to improve significantly the FEA solutions in predicting the forming load and the distribution of recrystallized volume fraction after forging.

A new equation has been derived on the basis of ${\delta}G^o$ = -RT lnK, linear behavior of the enthalpy of micellization with temperature, and the Gibbs-Helmholtz relation. It describes correctly the dependence of critical micelle concentration $(X_{CMC})$ on temperature and has yielded excellent fitting results for various surfactant systems. The new equation results in the linear behavior of the entropy of micellization with temperature and accounts for the compensation phenomena observed for the micellization in aqueous solutions, along with the linear dependence of the enthalpy of micellization on temperature. These results imply that the new equation of $X_{CMC}(T)$ accounts for the temperature dependence of CMC correctly.

PURPOSES : The purpose of this study is to evaluate the degree of restraint (DOR) of longitudinal steel at continuously reinforced concrete pavement (CRCP) against environmental loadings. METHODS : To measure the longitudinal steel strain, 3-electrical resistance and self-temperature compensation gauges were installed to CRCP test section (thickness = 250mm, steel ratio = 0.7%) and continuously measured 10 min. intervals during 259 days. In order to properly analyze the steel strains first, temperature compensation process has been conducted. Secondly, measured steel strains were divided into 12 phases with different events such as before paving, during concrete hardening, and after first cracking, etc. RESULTS : Thermal strain rate (TSR) concept is defined as the linear strain variations with temperature changes and restraints rate of longitudinal steel against environmental loadings (especially thermal loading) with different cases is defined as degree of restraint(DOR). New concept of DOR could be indirect indicator of crack width behaviors of CRCP. CONCLUSIONS : Before paving, DOR of longitudinal steel is almost same at the coefficient of thermal expansion of steel ($12.44m/m/^{\circ}C$) because of no restraint boundary condition. After concrete pouring, DOR is gradually changed into -1 due to concrete stiffness developing with hydration. After first cracking at crack induced area, values of DOR are around -3~-5. The negative DOR stands for the crack width behavior instead of steel strain behavior. During winter season, DOR reached to -5.77 as the highest, but spring this values gradually reduced as -1.7 as the lowest. Based on this observation, we can presume crack width decreased over time within the time frame of this study. This finding is not consistent with the current theory on crack width variations over time, so further study is necessary to identify the causes of crack width reducing. One of the reasons could be related to concrete stress re-distribution and stress relaxation.
