This study explores the effects of standardized management processes such as COBIT and ITIL on the success of IT outsourcing by utilizing an exploratory case study. The exploratory model includes the maturity of ITIL and COBIT process and success of IT outsourcing. For each construct of the model, several measures are developed from preceding researches and confirmed in the context of the cases utilized for this study. It is found that the maturity of the processes supported by ITIL and COBIT is critical for the success of IT outsourcing in this study. This results confirm the current popularity of the standardized process adopted in practice and also require further research endeavors in this control or management process in the future. It should include any other processes and related activities to the control process in the relationship of IT outsourcing.

This study analyzed whether the suitability of strategy is playing a regulative role between IT characteristics & user characteristics and non-financial performance empirically. To this end, this study set up IT characteristics and user characteristics as independent variables, and set up non-financial performance as the performance variable of KMS, and also set up the suitability of the management strategy & informatization strategy of a business as moderating variables. This study defined the detailed factors in IT characteristics as IT maturity and IT/IS infrastructure while defining the detailed factors in user characteristics as perceived profit, organizing of learning, and user professionalism. In addition, this study defined non-financial performance as an organization member satisfaction, and KMS availability. As a result of the analysis, IT maturity & IT/IS infrastructure, which are defined as IT characteristics, and perceived profit, organizing of learning and user professionalism, etc., which were defined as user characteristics, were found to be variables playing a regulative role in non-financial performance.

The risk of failure in the development of modern weapon systems has been increasing as the demand on the capability and the resulting complexity of the weapons on the war fields are increasing drastically. The analysis of failure has indicated that the main causes can be the following: one is attributed to the unsatisfaction of the system operation concept; and the other is the use of premature technology. As such, DAPA in Korea is urging that the weapons systems development should meet the required operational capability (ROC) as a critical performance requirement. On the other hand, an approach to risk management is to use the technology readiness level (TRL) assessed for each individual technology alone. However, the method of TRL cannot assess the effect of integration between technologies and cannot be performed at system level, which is crucial to systems development. In order to improve the shortfalls, a concept of system readiness level (SRL) has been studied by introducing the technologies integration and also some forms of analysis of advanced degree of difficulty studied separately, but no model considering both of two reported yet. In this paper, under the framework of meeting the ROC, an improved SRL assessment model is presented, which is also considering the advanced degree of difficulty simultaneously. The application of the improved assessment method is discussed in connection with the life cycle of the weapon systems development in conformance with the ROC of DAPA.

The Technology Readiness Assessment(TRA) has the advantage of identifying immature technologies in promoting weapon system research and development project. However, a more diverse set of information is required for the determination of phase shift and technical risk management for weapons system R&D projects. In this paper, we investigate the various indexes the various indexes proposed to overcome the limitations of the Technology Readiness Level(TRL) and analyze the possibility of applying to the actual weapons system R&D projects. Based on the analysis, it was possible to provide additional information that could not be presented in TRA using technical risk indexes other than TRL, confirming that it could be used for technical risk management for weapons system R&D projects.

The purpose of this study is to identify the relationships among Ego-Resilience and Psycho-Social Maturity, Stress Coping Styles, and influencing factors on Stress Coping Styles of university students. Data were collected from 200 male university students in A city from June 1 to 30, 2016. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficients, and stepwise multiple regression. Significant correlations were found among Ego-Resilience and Psycho-Social Maturity, Stress Coping Styles. Meaningful variables that influenced Stress Coping Styles were Ego-Resilience and Psycho-Social Maturity, grade, and the total explanation power was 38%. In conclusion, development of Stress Coping Styles program to decrease the stress of university students based on the convergent influencing factors is needed, and further development of scale for Stress Coping Styles for the university students in Korea based on the related factors is also needed.

This research paper is to identify factors affecting the need for international cooperation in defense science and technology sector. This study set a new hypothesis based on the previous research in terms of the theory of transaction cost, knowledge-based and technology readiness level perspective. After setting a new hypothesis, the following facts were found. First, it showed that the greater the importance of defense technology also increases the need for international technology cooperation for its technology. Second, the relatively higher distance of technology comparing to the developed countries was the need for international technology cooperation to be bigger. Lastly, the relatively higher technology readiness level of technology showed the negative relationship with the need for international cooperation. This results showed that the international cooperation in defense science and technology was regarded as complementary to get their short knowledge. The results of these analyzes showed that the international defense cooperation should be push forward based on the level of technology comparing to the developed countries and the technology readiness level.

In this study, the leaves of aronia (Aronia melanocarpa) across different stages of maturity were collected and their chlorophyll content, antioxidant content, and activity were analyzed. The leaves of the selected aronia cultivars ('Viking', 'McKenzie', and 'Kingstar K1') were harvested in June (young-stage leaf) and in August (old-stage leaf). The antioxidant content and activity of all three aronia cultivar leaves were significantly higher in the young-stage leaves than in the old-stage leaves. The main polyphenols in aronia leaves were catechol and chlorogenic acid, which tended to decrease as maturation progressed. As a result, the young-stage aronia leaves contained more abundant flavonoids, phenolic compounds, and polyphenols with higher antioxidant activity than those in the old-stage leaves. Overall, our findings indicate that aronia leaves contain potential bioactive compounds that could be used to develop functional food ingredients.

본 연구는 발달적 위기에 놓여있는 중년여성의 피로도와 스트레스 저항력 그리고 정서와의 상관관계를 알아보기 위하여 뇌신경 생리학적 지표인 뇌파 측정을 이용하여 분석해 보고자 하였다. 2005년 3월부터 2009년 6월까지 한국정신과학연구소에 뇌파 측정을 의뢰한 우리나라 중년여성 4403명(35세~65세)을 기준으로 선정된 뇌기능 지수(긴장도, 항스트레스지수, 정서지수)를 시계열 선형분석과 상관분석으로 한 결과 중년여성의 피로도, 스트레스 저항력 그리고 정서에는 밀접한 관계가 있었다. 그러므로 사회적으로나 가정적으로 성숙하고 책임감 있는 중년여성의 역할이 필요한 현대사회에서, 중년기의 심리적 생리적 문제에 적극적으로 대처하는 것이 개인생활은 물론 가족의 원만한 기능과 안녕을 유지, 증진하는데 반드시 필요하다.
