Physical resources are central to coping with economic hardships for people in low-income, yet life experiences such as resource loss and gain and their relationships with a sense of well-being received scarce attention. Thus this study investigated levels of loss and gain of physical resources, economic stability and well-being of 254 adults who participated in welfare-to-work programs; correlations and paths among these variables; and direct and indirect effects of economic stability by structural equation modeling. Major results were: first, the levels of resource loss and gain were below a moderate level and the level of gain was significantly higher than the loss level. Second, in the relationships with both economic stability and well-being, resource loss showed negative correlations, while resource gain showed significantly positive correlations. Third, the negative direct effect of resource loss either on the economic stability or on the well-being respectively was significant and the indirect effect on well-being through economic stability was also significant. Finally, the direct effect of resource gain on either economic stability or well-being was significant; and the indirect effect of resource gain on well-being was also significant. Thus in both models for resource loss and gain, the indirect effect of economic stability was significant, which supports partial mediation model. Based on these results, implications for social work practice and research were examined, particularly for enabling social work practice to utilize information regarding resource loss and gain, economic stability, and a sense of well-being that were embedded in the community life of people in low-income.

Space Treaty Article 2 stipuates non-appropriation by sovereignty, and in any other means. Interpretative controversies has continued as regards the meaning of any other means. It is not clear whether appropriation by private entity is also prohibited or not. Furthermore, the controverse around the binding force of Article 1 has made worse the controversy regarding such appropriation. U.S. Congress has enacted the law regarding the space resouce mining in 2015. Its main purpose is to alleviate legal unstability which U.S, private companies have faced, and it provides some provisions regarding private rights about space resources. Original bill, H.R. 1508 included the property right. Amendment to the bill is to ensure that an "asteroid resource utilization activity" is inter-preted as on a single asteroid and not on any asteroid. The use of the word "in situ" in defining space resources simply means resources in place in outer space; but any such resource within or on an asteroid would need to be "obtained" in order to confer a property right. The use of the word "in situ" in merely defining a space resource in the bill is not equivalent to claiming sovereignty or control over celestial bodies or portions of space. Further, there is clear Congressional direction in the bill that the President is only to encourage space resources exploration and utilization, including lowering barriers to such activity, "consistent with" and "in accordance with" US international obligations. Federal courts are granted original jurisdiction over entities defined in ${\S}$ 51301(4) and in-situ asteroid resources that have been removed from an asteroid by such entities. Federal courts are not granted jurisdiction over outer space, the Moon, other celestial bodies, or the asteroid from which the in-situ natural resource was removed. It is said that the Space Resource Utilization Exploration Act of 2015, talked about the rights of private players to own-kind of a "finders keepers" law.

This study began with the question of obtaining human resources through the promotion of outstanding resources of the Special Forces Officer and studied the following four promotion strategies: First, it is Facebook's promotional strategy medium. Second, it is a promotional strategy medium of YouTube. Third, it is a promotional strategy medium for blogs. Fourth, it is a public relations strategy medium for Web site. Furthermore, we would like to consider this study through four promotional strategies and cases of acquiring excellent foreign personnel in order to acquire excellent non-commissioned officers. Therefore, it is necessary to obtain excellent resources through promotional activities by utilizing strategic intermediaries for obtaining excellent resources from special forces. Ultimately, this study can provide fundamental implications for recruiting special forces officers for obtaining excellent resources by utilizing strategic intermediaries.

한국군은 무기체계획득의 비용, 성능, 일정에 대한 불확실성을 경감하기 위해 모델링 및 시뮬레이션(M&S) 기술과 정보기술을 활용하여, 새로운 전투개념 개발과 무기체계능력을 사전에 검증하고자하는 모의실험기반획득(Simulation Based Acquisition, SBA)을 적극 추진하고 있다. 이를 위해서는 M&S 소프트웨어, 데이터, 문서 등의 M&S 자원(콘텐츠) 확보가 무엇보다 시급하다. 본 논문에서는 2010년 국방 31개 기관을 대상으로 수행한 M&S 자원 보유현황 조사결과를 분석하여 M&S 자원 확보 방향을 제시하였다.

본 논문은 지역간의 경쟁을 통한 환경재의 획득과정에 대해서 분석하였으며, 특히 경쟁의 과정에서 자발적 참여집단 (critical mass)의 존재가 경쟁의 결과에 미치는 영향에 초점을 맞추고 있다. 환경재에 대한 지역간의 경쟁(지대추구경쟁)은 Katz-Nitzan-Rosenberg(1990) 모형을 기초로하여 분석하였으며 지역집단간의 경쟁에 있어서, 구성원은 비협조적 쿠르노-내쉬(Cournot-Nash) 방식에 의해서, 그 자신의 이익(지대)을 획득하기 위한 경쟁을 벌이는 것으로 가정하였다. 어떤 지역집단이 환경재 획득경쟁에서 이길 확률은 궁극적으로 그 지역에 유치될 환경재의 크기(화폐가치로 환산한)에서 받는 영향의 정도 ${\alpha}$( 단. $0{\leq}{\alpha}{\leq}1$)의 상대적 크기에 비례하여 결정된다. 그러나 환경재획득경쟁에서 발생하는 고정비용 M의 규모가 커지면, 그것이 특정지역의 자발적 참여집단의 최소규모 상향조정을 요구하게 되어, 자발적 참여집단의 수가 경쟁에 결정적 영향을 미칠 가능성이 많게 된다. 특히 환경재로부터 받는 영향의 정도인 ${\alpha}$의 값이 작은 집단은 큰 집단에 비하여 항상 더 많은 자발적 참여집단의 구성원 수를 요구받게 되며, 고정비용 M의 값이 계속 커짐에 따라 이러한 최소한의 자발적 참여집단의 구성원수의 증가속도도 경쟁집단에 비하여 점점 더 커지게 된다.

Knowledge contents acquisition has received very little attention in the study of knowledge management, unlike knowledge sharing and utilization. For an organization to generate and preserve a competitive advantage, it is vital that its knowledge contents be acquired. This study analyzes, by quantitative approach of surveys, the degree of activities of knowledge contents acquisition for the employees of a local government organization. The results show that the employees of a local government are not aggressively involved in knowledge contents acquisition activities. Lessons and implications of this study for management leadership are presented.

This study analyzed the effects of corporate dynamic capabilities on enterprise performance by using ambidextrous innovation activities as mediators, focusing on SME employees. The sub-variables of dynamic capabilities were divided into opportunity exploration capability, resource acquisition capability, and resource reconstruction capability. 282 questionnaires collected from small and medium-sized enterprises residing in the metropolitan area were used for empirical analysis. SPSS v22.0 and Process macro v3.4 were used to analyze the parallel multiple mediation model. First, the results of the analysis showed that opportunity exploration capability, resource acquisition capability had a positive (+) effect on the ambidextrous innovation activities, and the effect of resource reconstruction capability on ambidextrous innovation activities was not significant. Second, the ambidextrous innovation activities had a significant effect on the enterprise performance. Third, it was found that opportunity exploration capability and resource acquisition capability had a positive (+) effect on enterprise performance, and the effect of resource reconstruction capability on enterprise performance was not significant. Fourth, the ambidextrous innovation activity mediated the relationship between opportunity exploration capability and enterprise performance. Fifth, the ambidextrous innovation activity mediated the relationship between resource acquisition capability and enterprise performance. Sixth, the ambidextrous innovation activity did not mediate the resource reconstruction capability and the enterprise performance. As a follow-up study, it is necessary to find third mediators besides the mediators used in this study, analyze the serial mediation model through these, and study for the moderated mediation analysis through the conditional process model in which the moderator is introduced.

최근 사면의 안정해석분야에서 자주 사용되고 있는 확률론적 해석 방법은 현장에서 획득 되는 자료들의 분산이 심하고 충분한 양의 자료가 획득되지 못할 경우 자료 내에 포함되는 불확실성과 가변성을 효과적으로 다룰 수 있는 방법 중의 하나로 인식되어 왔다. 그러나 대개 확률론적 해석 방법에서 이용되는 몬테카를로 시뮬레이션기법(Monte Carlo simulation method)은 파괴확률을 산정하기 위하여 수 많은 반복적인 계산과정이 요구되며 따라서 많은 시간과 노력이 필요하다는 단점을 가지고 있다. (중략)

해양자원으로부터 상업적인 가치를 지니는 천연물질들을 획득하는 것은 일본의 수산업에 있어서 매우 중요하다. 일본에서는 해양자원의 부산물을 이용하여 다양하고 많은 상업적인 제품들을 성공적으로 개발하고 있다. 키틴, 키토산, 어유, 액정(liquid crystal), 프로타민(protamine, 식품에 향균제로 사용되며 물고기의 고환으로부터 얻음), 어류양식장에서 사용하는 성장호르몬, 해양생물로부터 추출하는 몇가지 의약품 등이 대표적인 예이다.
