The purpose of this paper is to show a way for extracting the core input and output variable in Korean seaports by using principal component analysis and DEA(data envelopment analysis). Two inputs(birthing capacity, and cargo handling capacity) and three outputs(export cargo handling amount, import cargo handling amount, and number of ship calls), and three cross sectional data(1995, 2000, and 2004) for 26 Korean seaports are considered for measuring the efficiencies of 21 DEA models. 21 models can be treated as variables and efficiencies as observations for extracting the core inputs and outputs variables by using principal component analysis. An empirical main result indicates that core input variable is cargo handling capacity, and core output is the number of ship calls. The Korean seaport authority can adopt the DEA and principal component analysis for deciding the development and investment to each seaport.

본 연구는 핵심역량 지향성을 중심으로 고찰한 IT 아웃소싱 성공요인 및 결과에 관한 것으로, 아웃소싱 프로세스 관리역량과 기업의 핵심역량 지향성이 IT 아웃소싱된 업무 복잡도와 아웃소싱 성과에 영향을 미치는 지, 그리고 아웃소싱 프로세스 관리역량이 기업의 핵심역량 지향성과 아웃소싱 성과의 관계를 매개하는 효과가 있는지에 대한 실증 연구이다. 따라서 본 연구는 독립변수로 핵심역량 지향성과 종속변수로 아웃소싱된 업무 복잡도 그리고 매개변수로 아웃소싱 프로세스 관리역량을 사용하였다. 국내 IT 아웃소싱 협회에 등록된 회사의 IT 부서를 대상으로 200 개의 데이터를 확보하였고 공분산 구조방정식 모델로 분석하였다. 연구결과, IT 아웃소싱 프로세스 관리역량은 핵심역량 지향성이 아웃소싱된 업무 복잡도와 아웃소싱 성과에 미치는 영향을 매개하는 것으로 밝혀졌다. 그리고 핵심역량 지향성은 아웃소싱의 성과에 긍정적인 영향을 미치지만 아웃소싱된 업무 복잡도엔 유의한 영향을 미치지 않는 것으로 나타났다.

The Purpose of this study was to empirically investigate the effects of core competencies on the management performance of hospitals and the mediating roles of medical service orientation and internal customer orientation. The sample of this study was composed of 307 employees from 18 general hospitals in Incheon Metropolitan City and Bucheon City. Data were collected with self-administered questionnaires and analyzed using structural equation modelling technique. This study found that core competencies had positive effects on the management performance of hospitals and that medical service orientation and internal customer orientation mediated the relationship between core competencies and the management performance of hospitals. The theoretical and practical implications of the results were discussed and the directions for future research were suggested.

Recently, the global financial crisis and the increasing number of unsold houses in Korea are construction companies to assess their efficiency. The most important factor in analyzing the efficiency of a company is the input-output variable. However, systematic stud the core input-output variables, which have a great influence on the efficiency analysis. Thus, to the core input-output variables for efficiency analysis of construction companies, this study propose a model that includes all combinations of input-output variables and to find the core input-output variables using the Data Envelopment Analysis(DEA) model and Principal Component Analysis(PCA). Existing research and theories were studied variables and 21 models were established to measure efficiency. were obtained that the core input and output variable in 2006 the number of employees and sales. For 2008, the core input variable was capital stock and the core output variable was quarterly net profit. For 2010, the core input variable was fixed asset and the core output variable was sales. Through obtaining the variables that greatly affect the efficiency of construction companies, it is considered that individual construction companies will be able to prepare a priority strategy to enhance efficiency.

The golden rule of CRM should be core customers. They show such passionate partnership with the company that they actively put forth their opinion to improve products and service through voluntary pro-company activities and participate in the development of new products through open innovation. Therefore, the top priority of a company should be given to defining its core customers and accurately understanding and managing them, which would contribute to the growth of the company. It has become more important nowadays how to manage a long-term customer relationship, for it can assure the company of increased income in spite of steep competition with rival companies. Therefore strong customer relationship is an important means of proving the company with competitive edge and maximizing company income.

Purpose: The purpose of this study was to investigate relationship among self-directed learning, confidence of performance, clinical learning environment and Clinical Competency of nursing students. Methods: 178 nursing students participated. Data analysis was performed using descriptive statistics, t-test, ANOVA and pearson's correlation coefficients with IBM SPSS Statistics 21.0. Results: Mean score of self-directed learning, confidence of performance, clinical learning environment and clinical competency was 3.36, 3.42, 3.20 and 3.66 points. There was significant positive correlation among self-directed learning, confidence of performance, clinical learning environment and clinical competency. Conclusion: Therefore, in order to improve the clinical competency of nursing students, it is necessary to systematize core nursing skills education and continuously improve the clinical learning environment through close industry-academia cooperation and relationship.

This Study's topic is to study on the effects of core competencies as such as leadership, strategic competences' influence towards the university-industry cooperation on technology transfer and education performances. First, the existing studies and literatures have been reviewed. Second, the nationwide surveys were conducted. In results, the leadership competence did not have any impact on the operation performances. Strategic competence did not have any impact on the technology transfer, but it influenced the education performance. Human resource competence also did not have any influence on the managing performances, but it has been analyzed that the R&D competence had an influence over the technology transfer part of the managing performance. The University-Industry Cooperations create an opportunity and secures competencies for the enterprise, it also enhances the R&D competency of University and provides supports in nurturing the human resources. Especially, the strategic competency amongst the independent variables has influenced the education performance.

Various studies have been conducted for drag reduction of a high-speed vehicle by injecting counterflow jet from its nose cone. In this study, in order to obtain baseline data and key parameters for drag reduction method, the counterflow jet study of the USA is reviewed and summarized. The nose cone shapes of each study are hemisphere cylinder, truncated cone, and reentry capsule, and their test conditions are summarized accordingly. Key parameters for drag reduction are jet mach number, mass flow rate, and pressure ratio. Even though drag reduction effects show various results according to given test conditions, it is found that the drag reduction effect reaches up to 40~50%.

본 연구는 Homans의 Social Exchange Theory에 근거하여 특정 공원의 매력도(attractiveness)와 핵심시설 (core facility), 핵심recreational program과의 관계를 규명하였다. 즉, 공원의 매력도를 일정 행동에 대한 가치로, 특정 공원의 방문을 개개인의 행동선택으로 생각하여 가설을 제시하고 검증을 한 결과 핵심시설과 핵심 recreational program이 증가함에 따라서 공원의 매력도가 증가함을 보이고 있다. 또한 설정된 모델은 두 변수로 특정공원의 매력도를 65% 설명하고 있다. 이 결과는 특정 지역의 자연조건과, 현재 또는 잠재적 이용자들의 선호를 바탕으로 핵심시설과 핵심recreational program을 도시공원이 제공해 주면, 그 공원의 매력도는 증가하며 따라서 공원시 만족도와 이용 빈도를 늘릴 수 있다는 구체적인 증거를 제시하고 있다.
