This paper analyzes the meaning of sustainability in sustainable development in the ecological ethics, and suggests the importance of ecological sustainability. In the discussion of ecological sustainability the relation between sustainability and change should be regarded as not conflictual but interactive. The concept 'ecological' in this context means network, and the concept 'sustainability' means the relationship between changing being(or beings) which constitutes ecological system and its unchanging being(or whole relation). So there are two axes of human and ecological system, and three elements namely network which means mutual dependence of human and nature, sustainability which means the maintenance of ecological relations, and responsibility which humans should take for the sustainability, in the ecological sustainability. The maintenance between being and relations of beings, changing sustainability, the priority of being to non-being, mutual interdependence on the basis of solidarity of beings are important values in the ecological sustainability.

CORBA는 분산 시스템의 객체를 관리하기 위한 모형으로 여러 응용에서 장점을 보인다. 그러나 CORBA 객체의 정의에는 지속성을 가정하고 있지 않다. 본 논문에서는 CORBA의 BOA(Basic Object Adapter)에 객체 데이타베이스 어댑터(Object Database Adapter, ODA)를 구현하여 객체를 관계 데이타베이스에 저장함으로써 객체의 지속성을 유지하도록 하였다. 객체의 관리는 객체지향 데이타베이스 시스템이 자연스러우나 본 논문에서는 이미 구축된 관계 데이타베이스 시스템과 응용을 공유할 수 있도록 관계 데이타베이스용을 구현하였다. ORB는 Orbix를 사용하였고, 튜플의 객체로의 대응은 Tie 법과 객체포장기 개념을 사용하였다. CORBA 응용의 관점에서 데이타베이스 시스템을 이용한 객체의 지속성 유지는 지속성 유지와 더불어 많은 수의 객체를 효율적으로 관리할 수 있고, 병행성, 회복기법 등을 이용할 수 있는 여러 장점이 있다. 또 데이타베이스 시스템 측면에서 CORBA와 데이타베이스 어댑터의 이용은 사용자에게 데이타베이스 스키마에 관한 사항을 숨김으로써 데이타베이스 접근을 쉽게 하고, 분산된 데이타베이스 환경에서는 데이타베이스 모델과 언어의 이질성을 해소할 수 있는 장점이 있다.

This study investigated empirically the structural relationship of golf participants' basic psychological needs, exercise emotion, and exercise-adherence behavior. Using two-hundred thirty questionnaires, the results were as follows. First, golf participants' autonomy, competence, and relatedness had a significant impact on the positive emotions. On the other hand, only competence lowered the negative emotions, and the other variables did not have a significant impact. Second, golf participants' autonomy, competence, and relatedness increased the exercise-adherence behavior. Third, golf participants' positive emotion increased the exercise-adherence behavior but a negative emotion decreased it. In terms of the indirect effect, golf participants' autonomy, competence, and relatedness influenced the exercise-adherence behavior, which was mediated by exercise emotion. This study is useful to sports participants interested in real value and a happy life through exercise-adherence behavior.

With a recent rise of various chatbot services, this study attempts to explore the role of chatbot users'' psychological characteristics by applying the self-determination theory. In particular,this study investigates (a) the relationship between chatbot users' psychological needs(perceived autonomy, perceived competence, perceived relatedness) and user satisfaction, continuous intention to use, and (b) the moderating effect of chatbot type and user motivations. Based upon a survey, the results revealed that perceived autonomy, competence, and relatedness had significant positive effects on user satisfaction and continuous intention to use. The results also confirmed that the user satisfaction had a significant positive effect on the continuous intention to use. The moderating effect of social and relational motivation was found between perceived autonomy, competence, relatedness and user satisfaction. The implications are discussed for furthering the development of chatbot services.

This paper reports on a study testing a model that articulates factors affecting duration of the relationship between exporters and importers. The model posits that affective commitment and calculative commitment influence duration of the relationship. Affective commitment of an importer toward an exporter is hypothesized to be predicted by social satisfaction, which in turn may be predicted by cultural familiarity, perceived similarity, and credibility. In contrast, calculative commitment is hypothesized to be predicted by economic satisfaction, which in turn may be predicted by opportunism and relationship performance. A survey of importers was conducted to test the model. The study results provided support for most of the hypotheses. Theoretical and managerial implications of the study results are discussed too.

This study is to evaluate the influence of relationship marketing and identify empirically the important factors which affect relationship continuity between multimodal transport operators and shippers. The empirical findings of this research are, MTO's marketing activity factors which consist of customers' contact intensity, relationship-oriented factors, positively affects relationship continuity such as revisit intention and word-of-mouth communication. As a result, relationship marketing activities are essential to the market strategy of MTO for continuous and stable growth. Also, on condition of transactional types, On-line transaction has an effect of customer switching, but there is no different effect in case of service type. Accordingly, international MTO in domestic need to develop various relationship marketing programs such as a special program for enhancing the continuity, an event for long-term customers and training program should be implemented and enforced to elevate qualify of the service encounter.

근래에 들어서 노인인구과 장애인구의 지속적인 증가로 인해 재활용 로봇 산업이 지속적인 관심을 받고 있다. 특히 재활 로봇은 환자의 삶의 질 향상과 밀접한 관계가 있고, 인간의 기능을 보조하는 시스템기술로 로봇공학과 밀접한 관계가 있는 분야이므로 더욱 주목받고 있다. 본 논문에서는 현재 활발히 연구가 진행되고 있는 다양한 재활 로봇의 기술 분류와 공개된 시스템의 개발현황을 소개하며 시스템들의 특징을 간략하게 소개하였다. 재활 로봇은 치료 목적 운동에 따라 다양한 형태로 개발될 수 있으며, 실제 상용화된 제품들이 있지만 임상적 효능과 실제 사용성 평가와 관련한 연구가 부족한 실정이다. 실사용자 및 의료계와의 지속적인 협력으로 지속적인 기술 개발의 필요성이 요구될 것으로 전망된다.

수문학 분야에서 하천유량은 중요한 요소이므로 신뢰성을 바탕으로 지속적이고 정확한 관측이 필요하다. 일반적으로 수위나 강우량의 경우 지속적이고, 자동적인 측정으로 비교적 정확한 관측이 가능하다. 하지만, 기술적인 한계와 경제적인 면에서 연속적인 유량측정이 어렵기 때문에 수위-유량 관계곡선을 이용하여 유량을 산정하고 있다. 수위-유량 관계를 통해 유량을 산정할 경우 계산방법과 분석과정에서 오차가 발생되고 산정된 유량의 오차로 이어지게 된다. 따라서, 신뢰성있는 유량 산정을 위해서는 수위-유량 관계곡선의 불확실성을 감소시키는 것이 중요하다. 본 연구에서는 Bayesian 회귀분석 및 Bootstrap 방법을 이용하여 수위-유량 관계 곡선식의 매개변수를 추정하였다. 또한 앞의 2가지 방법의 적용성을 평가하기 위해서 기존 방법인 최소자승법에 의한 매개변수 추정치 결과의 신뢰구간을 비교분석 하였다. 본 연구를 통해 다양한 통계학적 방법을 이용한 결과로부터 수위-유량 관계곡선의 불확실성을 감소시키는데 효과적인 방법을 찾고자 한다.

The present study is aimed to investigate antecedents(person-job fit, human capital investment) and outcome variable(subjective career success) of continuous-related career learning, and to demonstrate mediating effects of continuous-related career learning. The data which was applied to analysis was collected from 241 office workers who have worked for automobile company in Ulsan and public companies in Jeju and applied temporal separation of measurement as an alternative for common method bias. The results are as follows. First, person-job fit, human capital investment affected to career-related continuous learning positively. Second, the impacts of career-related continuous learning to subjective career success was positively significant. Third, the mediating effects by career-related continuous learning demonstrated statistically significant in the links between antecedents-outcome variables as partial mediation. Implications of this study contribute to expand research area of continuous-related career learning with regard to job and organizational variables, and to facilitate of research interests on subjective career success. In addition, the mechanism of career advance was empirically proved by continuous-related career learning.

This study is to identify how social capital is accumulated and used in SNS space, furthermore, is to examine the impact of structural and relational social capital on SNS user satisfaction, and continuous intention of information sharing. The empirical test showed that social interaction ties have a significant and positive impact on relational social capital(trust in SNS site, trust in SNS user, reciprocity). In addition, it was proven that trust in SNS site played a critical role in satisfying SNS user whereas trust in user and reciprocity was not related to SNS user satisfaction. Finally, trust in SNS site and reciprocity were proven to be key determinants of continuous information sharing intention, whereas trust in user was not related to continuous information sharing intention.
