Purpose: The purpose of this research is to identify the factors effecting on the software firm performance through RBV(Resource-Based View) perspective. Methods: The data have been analyzed via the multiple regressions between 3 performance indexes, which are revenue, operational income rate and employment, and 7 independent variables. Results: The results show that company age, capital intensity, training expense, marketing expense, and export revenue effect on the firm performance, whereas R&D expense and debt ratio do not so. Conclusion: This study can contribute the decision process of the investment priority of resources and competencies at the software firms to maximize the return on investment.

Capacity payment mechanism has been adopted as the incentive scheme to achieve resource adequacy in Korean electricity market, however, the level of capacity price has been controversial due to its insufficient extent to incur financial loss for certain generators. Therefore, a new method is proposed to estimate the proper level of capacity price incorporating profitability of market participants and resource adequacy in this paper. The proposed method is successfully applied to test system based on Korean power system.

The management of organizational Human Resource is steadily shifting away from pure hierarchical to market mechanisms that involve external vendors. HR Business Process Outsourcing (BPO) has recently emerged as a significant administrative innovation in an organization's strategy. Our paper attempts to understand firm-specific factors influencing the scope of HR BPO needs. Study results show that IT maturity and firm size are influential factors on the scope of HR BPO needs. We hope that our attempt at empirically examining and predicting this emergent phenomenon will stimulate others to look at this important strategic challenge facing firms from a theoretical perspective. Such research initiatives will allow us not only to better understand this complex phenomenon, but also to drive useful management prescriptions grounded on theory-based research.

쿠버네티스는 컨테이너 통합 관리를 위한 대표적인 오픈소스 기반 소프트웨어로, 컨테이너에 할당된 자원을 모니터링하고 관리하는 핵심적인 역할을 한다. 컨테이너 환경이 보편화됨에 따라 컨테이너를 대상으로 한 보안 위협이 지속적으로 증가하고 있으며, 대표적인 공격으로는 자원 고갈 공격이 있다. 이는 악성 크립토마이닝 소프트웨어를 컨테이너 형태로 배포하여 자원을 탈취함으로써, 자원을 공유하는 호스트 및 다른 컨테이너의 동작에 영향을 끼친다. 선행 연구는 자원 고갈 공격의 탐지에 초점이 맞춰져 있어 공격 발생 시 대응하는 기술은 부족한 실정이다. 본 논문은 쿠버네티스 환경에서 구동되는 컨테이너를 대상으로 한 자원 고갈 공격 및 악성 컨테이너를 탐지하고 대응하기 위한 강화학습 기반 동적 자원 관리 프레임워크를 제안한다. 이를 위해, 자원 고갈 공격 대응 관점에서의 강화학습 적용을 위한 환경의 상태, 행동, 보상을 정의하였다. 제안한 방법론을 통해, 컨테이너 환경에서의 자원 고갈 공격에 강인한 환경을 구축하는 데 기여할 것으로 기대한다.

The purpose of this study was to verify a Structural Equation Model that constructed the causations among the leisure constraints, leisure. motivation, and leisure participation. This model posits that constraints determine motivation to participation. Concretely, structural and interpersonal leisure constraints(contextual factors) will affect interpersonal leisure constraints in the light of ecological perspective. Also, leisure constraints will affect leisure motivation based on self-determination theory that may influence leisure participation indirectly. A survey questionnaire was administered to 301 elderly in an institution for the elderly. A measurement model and a structural equation model estimates by Maximum Likelihood method(ML method) utilizing LISREL 8.0 ver. The analysis showed that a goodness of fit is good of structural equation model presented in the study. And, all hypothesis adopted about causations among the leisure constraints, leisure motivation, leisure participation.

As the city have been enlarged bigger and more complicated recently, a discussion about a city right, started on the base of perception that a city must be recognized as a public resource and the value. A city rights imply equal use and participation in these city resource. From a start of modern city, a city space have been developed mainly, as a man's economic business and industrial area, but now, to ensure a woman's city right is getting an important factor of citizen's settlement. Then many domestic cities tries to promote a woman friendly city creation. The main purpose of this paper is to find the concept of woman friendly city, based on a gender-sensitive perspective view point and to make an assessment index of Woman Friendliness of the City (WFC). In a case of Ansan City which city is in the planning stage of application for a woman friendly city.

The purpose of this study was to analyze the impact of parental resources and parenting stress on parenting efficacy in low-income families Furthermore, in order to verify whether parental resources function as a resilience factor, a structural model was established to assess the suitability and influence of the variables. A total of 603 parents of children and adolescents between the ages of 9-18 were selected from the data from Children and Adolescents Comprehensive Status Research (2009) by the Ministry for Health, Welfare and Family Affairs. For the analyses, SPSS WIN 18.0 and AMOS 18.0 were utilized. The major results were as follows: First, the suitability of the model was confirmed with variables presenting a satisfying fit. Second, parental resources had a negative effect on parenting stress and a positive effect on parenting efficacy. Third, parenting stress had a negative effect on parenting efficacy. Finally, a test of the structural equation model supports the hypothesis that parental resources have a significant direct effect as well as an indirect effect through parenting stress on parenting efficacy. The implications for further studies and practice were discussed.

The purpose of this research is to analyze big data structure and various objects in big data industry based on ecological perspective. Big data is rapidly emerging as a highly valuable resource to secure competitiveness of enterprise and government. Accordingly, the main issues in big data are to find ways of creating economic value and solving various problems. However big data is not systematically organized, and hard to utilize as it constantly expands to related industry such as telecommunications, finance and manufacturing. Under this circumstance, it is crucial to understand range of big data industry and to which stakeholders are related. The ecological approach is useful to understand comprehensive industry structure. Therefore this study aims at confirming big data structure and finding issues from interaction among objects. Results of this study show main framework of big data ecosystem including relationship among object elements composing of the ecosystem. This study has significance as an initial study on big data ecosystem. The results of the study can be useful guidelines to the government for making systemized big data ecosystem and the entrepreneur who is considering launching big data business.
