These days our society, no matter it is individual or community or nation it has diversity big and small trouble and Terrorism, disaster that gives national crisis in many different ways. Before we dont think disaster is big problem in nation crisis but now we have to think seriously and put the disaster problem in nation crisis. Also security terrorism is important in national crisis just same as security of nation and disaster in national crisis management. Specially, attacking national sovereign and the head of the government are still increasingly and if deadly terror happens than nation will get big crisis and can get aftereffect. Accordingly way of development about crisis control in security terrorism, first of all, for make confrontation system because of crisis management, need judical revision about escort law and prevention of terror. Second of all, need exclusion of guard danger element for strengthening guard safe action. Third of all, strengthening education to people so increase ability of conquest in the scene. Finally, security terror not only directly purpose also indirectly purpose increase, need to development about guards way and need a strong will to reduce terrorism, also put emphasis on prevention guards action and before the fact make perfection more perfect in crisis control to removal element of terror.

This study analyzed the effects of Employee Value Proposition (EVP) and the impotance of a job rotation system on the subjective career success. The total 379 samples were surveyed from employees engaging in domestic hotel enterprises located in Seoul using convenient sampling method. The result of this research is as followings. First, EVP has total 5 factors('career development,' 'affiliation,' 'work environment,' 'work content' and 'pay & reward') and job rotation has total 3 factors('individual capacity improvement,' 'procedural justice,' and 'career development'). Second, the results of hypotheses test using a series of multiple regression analysis indicate that EVP factors including 'career development,' 'affiliation,' 'work environment,' and 'work content' influence subjective career success. However, EVP factor of 'pay & reward' does not influence subjective career success. Similarly, EVP factors excluding 'pay & reward' affect a job rotation system. Lastly, a job rotation system positively affects subjective career success. Based on the analysis results, we could draw the importance of the non-financial reward instead of financial reward in the perception of employees' subjective career success. As a research implication, the importance of the creative organization culture was suggested in the conclusion section.

As a way to gather diverse information required for everyday living, the importance of social networks has been growing. Social network services have been spreading rapidly because of diffusion of the Internet, evolution of social network sites, and recognition of the importance of social networks. Recently, the social network service has been evolved based on a new paradigm, Web 2.0, pursuing participation and openness. Following the adoption of Web 2.0 technologies, the social network service allows users to make and maintain new relationships in a more convenient way. Users of the social network service tend to reveal their personal information, and share their ideas and content with other people; in the process they become aware of their existence, feel satisfaction with life and exert influence to others as a member of the society. This study uses higher order factor analysis to analyze factors that affect the intention of using the social network service. A research model was developed with second-order factors including perceived social presence, perceived gratification and perceived social influence. First-order factors are grouped by technical, individual and social factors. Smart PLS 2.0 was used to conduct empirical analysis. The analysis results supported the validity of the research model.

This research examines the relation of dissatisfaction about own real conditions, deviant labeling, self-esteem, abuse from parent, victimization and juvenile delinquency(smoking, drinking, run-away, assault, taking away stuffs or money, larceny). The evidence of a strong relation of these factors and girls' delinquency is well known through empirical researches by feminist criminologists. Feminist criminology had attention to the gender-specific factors that could explain girls' delinquency. Most of conventional delinquency theories, such as social bond theory, differential association theory, focused on bad boys' deviant behaviors. These theories has not been designed to apply to girls' troubles. According to the conclusion of the research, there seems to support researches of feministic perspectives.

This study analyzed the sufficient conditions for Korean firm's foreign subsidiaries in order to evolve into a center of excellence for knowledge creation and diffusion. In this respect, the purpose of this study is to develop a new framework based on literatures related to subsidiary knowledge creation and a center of excellence. Specifically, we created seven decisive factors for subsidiary knowledge creation: two general factors, two strategic important factors, and three excellent factors. Each factor can be a necessary condition or sufficient condition according to research purpose. For example, the decentralized organizational structure belonging to general factors become a sufficient factor for facilitating subsidiary's knowledge creation but it become a necessary condition for a center of excellence because all subsidiaries with decentralized organizational structure cannot be strategically important subsidiaries. By using seven decisive factors, this study examines the determinants' validity theoretically and practically.

Recently, electricity industry is facing high market uncertainty which has ever had and which increase risks in power market. In this study, we analyze risk factors such as discount rates, initial investment (overnight cost), plant factor, fuel cost, carbon price, etc, for the perspective of investor. For the analysis of risk factors, we used LCOE method. The results of this study show that renewable energy is more affected by plant factor and overnight cost than other risk factors. First, Renewable energy has higher proportion of overnight cost in the total investment than that of other technologies. Second, renewable energy is free of fuel cost and carbon price so plant factor is the most important factor, in other words, competitiveness of renewable energy depends on plant factor. Furthermore, we conducted economic feasibility of wind power and PV in domestic case study. The minimum requirement condition to get profitability is that plant factor 15% and overnight cost \6,000,000/kW and 26%, \2,200,000/kW for PV and Wind Power, respectively.

화석연료의 고갈과 온실가스 배출의 증가로 지속 가능한 친환경 에너지 생산이 요구되는 가운데, 태양광 발전은 이러한 조건을 만족시키는 에너지 생산 방안으로 주목받고 있다. 태양광 발전은 태양 직사광을 이용한 발전 방법 때문에 실외에 설치되어야 하며 이에 따라 외부의 충격이나 오염물질로부터 태양전지 패널을 보호하기 위한 보호층이 필수적이다. 그러나 보호층에 의한 입사광의 반사 및 먼지나 황사에 의한 보호층의 오염 등은 태양전지의 발전 효율을 감소시키는 요인으로 작용하여 이에 대한 대응이 필요하다. 본 연구에서는 PET 필름에 나노 임프린트 리소그래피 및 핫 엠보싱 공정을 이용하여 moth-eye 반사방지 패턴을 형성함으로써 보호층에서의 입사광 반사를 억제하였다. 또한, 이러한 반사방지 패턴에 초소수성 자기조립단분자막을 코팅하여 표면 에너지를 낮춤으로써 먼지 및 황사에 의해 오염되었을 경우에도 빗물에 의해 오염 물질이 쉽게 씻겨 내릴 수 있는 자정기능을 부여하였다. 이러한 반사방지를 통한 입사광 투과량의 향상 및 초소수성 표면에 의한 자정작용에 의하여 태양전지의 발전 효율이 증가되었다.

태양광 발전에 있어서 실제 태양광 셀 특성은 날씨와 같은 환경 요인에 의존적이기 때문에 다양한 동작 조건에 대한 태양광 셀의 특성을 전력변환장치를 통해 테스트하기 위해 많은 시간과 비용이 소요된다. 이러한 문제를 해결하기 위해 Power Hardware-In-the-Loop Simulation (PHILS) 기술을 이용해 태양광 발전용 전력변환장치 시제품의 테스트 시간 및 비용을 단축할 수 있다. PHILS는 실시간 모의시험장치와 외부 입력이 가능한 전력변환장치로 구성되며, 해당 장치에서 모델의 동특성을 실시간으로 연산하기 때문에 모델이 복잡할수록 고성능 모의시험장치가 요구된다. 태양광 셀 모델의 출력 전압은 수치해석 기법을 통해 계산되고, 수치해석 기법의 종류와 초기 값에 따라 연산 시간 등의 성능이 변화하므로 적절한 기법을 선정하여 모델의 연산시간을 감소시킬 수 있다. 본 논문에서는 수치 해법 분석을 통한 태양광 발전의 PHILS를 위한 태양광 셀 모델의 연산 성능향상 기법을 제시하고, 실제 태양광 발전용 PHILS를 구현하여 실험적으로 제안하는 기법의 성능을 검증한다.

대부분 선진국 수산업은 국가경제에 차지하는 비중은 미미하나 해양생태 보전이나 해양식량안정 등의 중요성을 고려하여 국가개발 전략적 관점에서 큰 관심을 둔다. 그리고 인구나 식량소비 규모에 비해 수산자원이 풍부한 저개발국의 수산업은 국가경제 발전의 주요한 산업적 역할을 수행한다. 최근 한국을 포함한 일부 선진국에서는 창조경제적 수산업을 통하여 새로운 성장동력을 개발하여 수산업의 산업적 역할을 보다 산업화하는 전략적 발전을 지속적으로 추진하고 있다. 수산업의 창조경제적 발전은 주로 수산자원의 합리적 보존관리, 어업인의 소득증대와 어촌사회 복지향상뿐만 아니라 새로운 수산물 시장수요 창출 등에 주안점을 두고 있다. 본 연구에서는 수산창조지수(ICSF; Index of Creativity Space for Fisheries)를 분석하여 수산업의 지속적 개발 내지 회복에 있어 창조경제적 요인의 역할과 중요성을 평가하였다. 수산업의 창조성을 결정하는 수산창조지수(ICSF)는 기술(technology), 재능(talent), 다양성(tolerance)의 결합적 결과로 구성된다. 이를 통하여 창조경제적 측면에서 수산업의 지속적 발전 가능 잠재력을 평가하게 된다. 수산창조지수(ICSF)를 이용하여 한국 수산업이 지니는 창조성을 분석한 결과 대부분 수산분야에서 창조성을 기반으로 하는 지속적 수산업 발전 전략에 높은 관심을 보였다. 특히 한국 수산업은 보다 효과적인 자원 및 어업관리 정책의 이행을 통하여 창조경제적 편익의 증대를 모색하는 전략이 높이 평가되었다.
