The User Created Contents (UCC) are traded actively on the on-line market. The current pricing policy on the UCC market is the fixed pricing, which is set by the seller once and price never changes again. However market demand and supply are changing hourly, so the studies about dynamic pricing to determine more properly have been carried out. This paper suggests dynamic pricing models for UCC by analyzing the customer's searching pattern. We propose 2 pricing models (trend change-based pricing model and relative pricing model), and experiment various status by controlling system and market variables. We demonstrated our model by computational modeling and simulation. The result of this research can be useful guidelines to increase the revenue and profit of the UCC Market.

This study examined the relationships among ego resilience, career decision-making self-efficacy and job-seeking stress of senior nursing students. Data was collected through self-reporting questionnaire to 175 nursing students 3rd and 4th grade. Stepwise multiple regression revealed grade, career decision-making self-efficacy, satisfaction on university life to be significant predictors of job-seeking stress. These variables accounted for 13.5% of job-seeking stress. Therefore, it is necessary to reduce the job-seeking stress of senior nursing students through multidisciplinary intervention which strengthens career decision-making self-efficacy considering grade, satisfaction on university life.

The purpose of this study is to find out primary policies for reducing PM(particulate matter) as well as for improving the quality of life. Serious particulate matters cause to diverse healthcare and economy problems including business transactions. Unfortunately, until recently there are very few researches regarding the decision-making process for particulate matter policies. This study has applied the AHP(Analytic Hierarchy Process) method to develop cooperative policy making processes. The upper layer of this hierarchy analysis consists of four parts, i.e., transportation, production facility, living environment, and urban planning management. And each upper layer parts has their own three policies. 25 experts including policy-makers, academic researchers and industrial specialists have decided the primary policies and directions. The most significant PM policy is the mandatory reduction of air pollution and suspension of factory operation in the production industry. The results of this study can lead to guidelines for making environmental policies.

The aim of this paper is to explore the trend and structural features of unemployment in Germany and to review the local and regional labour market policy against the unemployment. Unemployment has been one of the major issues in Germany since the oil shocks oi 1973-74 and 1978-80. The unemployment rate in western Germany was low at the time of reunification in 1990 and the next consecutive two years. Since then, the unemployment rate has sharply risen due to the restructuring of industries. In an effort to reduce the unemployment and to search (or new employment policies, the specific roles and advantages of communal units have been appreciated. The local and/or regional labour market policies are characterized as fellows: the corporative networking of all the agents including local administration, education institutes, regional labour bureau, firms and interest groups; the systematic integration of the various instruments which have been separately installed by different sectors; and the target-oriented adjustment of labour market approaches in the local circumstances.

Order Review/Release(ORR) 시스템은 생산계획 시스템과 작업현장간의 연결고리로서, 작업현장으로의 작업투입을 조절하여 작업현장에서의 체류시간과 공정중재고, 리드타임의 변동을 줄여주는 역할을 한다. 그러나, 지금까지의 ORR에 관한 연구들은 ORR의 유효성에 관하여 명확한 결론을 내지 못하고 있다. 일부는 ORR이 작업의 전체 리드타임을 증가시키는 악영향이 있음을 주장하고, 일부는 ORR을 도입함으로써 작업현장에서의 리드타임과 공정중재고가 줄어들고, 안정화될 수 있다고 주장한다. 본 연구는 어떠한 환경에서 Order Release 정책을 도입하는 것이 시스템의 성능향상에 기여할 수 있는 지 확인하는 것을 목적으로 하고, 가상의 Job Shop을 대상으로 시뮬레이션을 수행하였다. 작업장가동률 수준과 생산계획 단계에서의 계획오더 이송간격을 환경분수로 설정하고, 작업현장의 부하를 고려하여 작업투입을 통제하는 다섯 가지 Order Release 정책과 세 가지 우선순위 규칙을 적용하여 실험하였으며, 리드타임, 납기, 공정중재고 등과 관련된 8가지 척도에 대해 각 정책을 평가하였다. 그리고, 계획시스템의 부하평준화 기능이 존재할 때, Order Release 정책의 도입으로 인한 효과가 더 크다는 기존의 연구결과를 검증하기 위해, 부하평준화를 적용하였을 때 Order Release를 통제하지 않는 정책과 통제하는 정책간의 성능향상 차이가 있는지를 확인하는 실험을 수행하였다. 실험결과, ORR 보다는 우선순위규칙이 시스템의 성능을 결정하는 주요 통제정책으로 밝혀졌다. 그러나, 생산계획시스템에서 1주 간격으로 계획오더를 이송할 때는 Order Release 방법을 적용하여 작업현장에서의 평균 리드타임과 리드타임의 변동, 공정중재고가 줄어드는 결과를 보였고, 가동률 수준이 높을수록 ORR 방법간의 차이가 크게 나타났다. 그리고 부하평준화 기능은 Order Release 정책의 유효성에 별 영향을 주지 않는 것으로 나타났다. 결론적으로, Order Release 방법은 우선순위규칙간의 성능차이를 줄이거나, 대체할 수 통제 기법이라기보다는 우선순위규칙을 보완하여 공정중재고와 작업현장에서의 리드타임, 리드타임의 편차를 줄여주는 역할을 한다고 볼 수 있다. 그리고, 계획시스템이 존재하여 계획오더가 일정기간간격으로 이송되는 환경에서 특히 유용하다는 결론을 얻었다.

This research paper examined to the influencing factors to adopt national policies of international organization's environment. For this a multivariate regression model has been used to examine cross-national differences in environmental policy adoption. The data analysis was conducted by regression analysis, the indexed point of international environmental agreements were ratified by each nation on the measure of independent variables for a sample of 130 countries in all parts of the world. From analysis results, overall, the regression analysis illustrates that the regression model generally fits our predictions for independent variables. The finding has revealed that external determinants are stronger than internal ones in explaining the level of national environmental policy adoption in relation to international environmental cooperation. Namely, All international environmental organizations, international nongovernmental organizations, and regional multinational institutes proved to function in a positive way in influencing number nations to have a favorable attitude toward international environmental policies. The findings of this study will provide helpful information on how to improve the efficacy of the Korean environmental policy system.

The purpose of this paper is to examine whether strategic decision-making processes are related to decision effectiveness, using a longitudinal field study design. We studied 120 decisions to determine if procedural rationality and political behavior influence decision success, controlling for the goodwill of the environment and decision implementation. Our results indicate that decision-making processes are indeed related to decision success. Results are discussed in terms of the importance of strategic choice in environmental organizations. these studies often provided simple fragments of empirical tests without a well developed theoretical framework. This study attempts to fill this gap by examining policy adoption, specifically by investigating influences on policy decision making across 120 nations using multiple-regression analysis. The greater the number of international NGOs in which a national governmental participates, the more the nation is apt to adopt international environmental policies to see how real affect.

The purpose of this study is to describe the mediating effect of career decision level on the relationship between career decision self-efficacy and career preparation behavior of nursing students. The subjects of the study were data collected from 108 nursing students in 3rd and 4th grade and analyzed. The factors affecting career preparation behavior of nursing college students were career decision self-efficacy (β= .54, p<.001) and career decision level (β =.23, p=.009). Career decision-making levels were found to play a partial mediating role in the relationship between efficacy and career readiness behavior (Z=2.49, p=.006). The results of this study suggest that it is necessary to improve the career decision-making self-efficacy and the level of career decision-making for effective career preparation behavior, and it is necessary to develop strategic career guidance and program that reflects this.

This study estimates the technical efficiency and total factor productivity(TFP) of and analyzes the relationship between TFP and exports for Korean manufacturing companies from 2000 to 2016. Specially, TFP is decomposed into Technical Change(TC), Technical Efficiency Change (TEC), and Sale Effect(SE), and compared between large and small enterprises. First, in the case of technical efficiency, the Korean economy has been very vulnerable to external shocks, such as the sharp decline following the 2008 financial crisis. The efficiency of the electronics, automobile, and machinery sectors is low and needs to be improved. In addition, the technological efficiency of large enterprises is higher than that of SMEs in most manufacturing sub-sectors except for non-ferrous metals. In the case of TFP, most changes are due to TC, and the effective combination of labor, capital and the effect of scale have little effect, suggesting that improvement of internal structure is urgent. In addition, volatility due to the impact of the financial crisis in 2008 was much larger in SMEs than in large companies, so external economic impacts are more greater for SMEs than large enterprises. The relationship between TFP decomposition factors and exports shows that TC has a positive effect only on exports of SMEs. Therefore, in order to increase exports, in the case of SMEs, R&D support to promote technological development is needed. In the case of large companies, it is necessary to establish differentiated strategies for each export market, competitor company, and item to link efficiency and scale effect of exports.
