This study investigates factors that affect the transformation of multiplex tie into one specific type of relationship - competitive relationship. In particular, this study argues that the lower technological distance or gap of technological competency, the higher the chances are for the multiplex tie to become a competitive tie. In addition, technological characteristics of the firms are also found to affect the multiplex tie's transformation into the competitive tie. To study this phenomena, this study uses both quantitative analysis and case study method. This study is an exploratory attempt to find factors relevant to change multiplex ties into competition, contributing to the literature of multiplex ties by identifying technological variables that affect the transformation of such ties. This study also contributes to practices by providing the guidance on what strategies firms should implement in complex situations such as multiplex ties.

This study applied self-determination theory to investigate the relationships between volunteers' perception of supervisors' autonomy support, volunteering motivation, and persistence intentions among collegiate students. Collegiate volunteers(n=515) involved in volunteer activities completed measures of supervisors' autonomy support, 5 forms regulation, and persistence intentions. Bivariate correlations indicated that volunteer motivation demonstrated an ordered pattern of relationships, such that adjunct points along the regulatory continuum would be more positively associated with on another than distal points. Analyses using structural equation modeling revealed that supervisors' autonomy support was positively related to more autonomous motivation(intrinsic motivation and identified regulation), while was natively associated with amotivation. Amotivation was negatively related with persistence intentions, and more autonomous motivations(intrinsic and identified) predicted grater intentions to continue with volunteer activity for next 6 months. The findings are discussed in light of the self-determination theory.

대규모 댐과 같은 수공구조물의 파괴시 상당한 피해가 발생하므로 구조물설계시 가능최대강수량(PMP) 기준이 적용된다. 포락선 방법은 가장 극심했던 강우량의 포락선을 작성하여 PMP를 산정하는 방법으로 기상 및 강수량자료가 부족시 PMP 추정이 어려운 경우에 사용한다. 포락선의 근사식은 지속시간의 거듭제곱인 멱함수 형태로 나타내며, 우리나라의 경우 1일을 전후로 계수와 차수가 다른 식을 사용한다. 이러한 근사식은 우리나라의 이상홍수 발생빈도 및 규모가 커짐에 따라 검토될 필요성이 있다. 또한, PMP 산정시 활용하는 제한된 수의 지상관측자료는 시공간적 변동성을 완전히 포착할 수 없어 한계가 있다. 본 연구는 이러한 한계를 극복하기 위하여 기상레이더 자료를 기반으로 우리나라 전역의 최대 강우깊이-지속시간 관계를 분석 및 새로운 PMP 포락선을 제시한다. 활용한 레이더는 CMAX(Column Maximum)로 2009~2018년간 10분 단위자료를 수집하였다. 레이더 자료와 비교하기 위하여 지상관측자료 AWS를 함께 수집하였다. AWS는 1997~2022년간 1분 단위자료로 우리나라 전역의 547개 지점관측자료를 활용하였다. 레이더자료는 Z-R 관계식으로 변환하여 가외치(outlier)를 제거 및 보정하였다. 그 후, 정규 크리깅기법으로 생성한 지상관측 강우장과 병합하는 CM(Conditional Merging)기법을 적용하였다. 우리나라 최대 강우깊이-지속시간 관계를 산정한 결과, 기존 포락선의 값이 낮게 산정되었음을 확인하였다. 이는 기후변화 등에 따라 최근 극한 호우가 발생한 것으로 판단된다. 또한, 실제 근사식은 멱함수 거동에서 벗어난 형태로 나타났고, 지점관측자료가 기상레이더 값보다 과소추정되는 경향을 확인하였다. 특히 같은 기간에서 확인하였을 때, 강우지속시간이 짧을수록 AWS값과 레이더자료의 강수량이 2배 정도 차이를 보여 지점관측소가 없는 지역의 국지성 호우 존재를 확인할 수 있었다. 추후, 미래에 더 긴 레이더 시계열을 사용한다면, 더욱 신뢰성 있는 자료로 활용할 수 있을 것으로 판단한다.

1980년대 후반과 90년대 초반부터 정보시스템의 비상계획과 재해복구의 새로운 개념으로 대두된 업무지속성관리(BCM:Business Continuity Management)는 정보시스템이 조직의 업무처리(Business Process)에 중심을 두고 활용되는 현실에서 업무의 중단없는 지속적인 업무수행이 조직의 중요 이슈로 대두되는 추세를 반영하여, 비상시 또는 재해시 복구의 대상을 단순한 전산센터나 시스템 단위에 초점을 맞추는 것이 아니라, 가장 중요한 업무처리 차원에서 중단없이 업무를 수행할 수 있도록 관리하는 것을 말한다. 본 연구에서는 이러한 업무지속성관리가 기존의 재해복구나 보안관리 등의 개념들과 어떠한 관계를 갖고 있는지를 정의함으로서, 업무지속성관리의 개념과 범위를 좀 더 명확히 하고, 정보시스템의 운영환경별(중앙집중처리, 분산처리, 외부위탁처리) 업무지속성관리를 적용하는 방안에 대해 살펴보고자 한다.

The current study investigated how interpersonal trust is developed in online communities, where most of individual identities are unknown or doubtful. To better understand and theorize the underlying mechanism, a survey was conducted integrating the literature on computer-mediated communication (CMC) and extending previous research on social identify model. The findings confirmed that integrity, benevolence, and openness are essential components in the concept of trustworthiness, which is predicted by social identification and persistency of communication activities in the virtual community.

This study has two primary purposes, firstly to identify how job dissatisfaction and continuance commitment influence to creativity, secondly to explore how coworker helping and support, and perceived organizational support moderate between interaction of job dissatisfaction and continuance commitment, and creativity. The first part of the study, based on literature study on creativity, provides insight into what are antecedents and moderate variables in creativity. In the second part of the study, a comprehensive research model and hypothesis were empirically tested based on data from 322 employees in Korean organizations. The results of statistical analysis show the following. First, job dissatisfaction has positive effect on creativity. Second, interaction of job dissatisfaction and continuance commitment does not have positive effect on creativity. Third, there was not any moderating effects between interaction of job dissatisfaction and continuance commitment, and creativity in this study. The last part of this study, a theoretical and practical implication of the study, and the future research agenda are presented.

It a very important part to keep a good relationship with supporters to promote the activities smoothly in non-profit-making organizations. The donation, a financial source of non-profit-making organizations, and the volunteer activities of supporters are also born from the identity with the supportive organizations. This research is a study about the relationship sustainability with supporters and supportive organizations, which is practiced with the variables of image, service quality, ethics, activity, satisfaction, trust, and intent of sustaining their support of supportive organizations. This research aims at making the model of relationship-sustaining intent of supporters and supportive organizations on the bass of the relationship between the conceptual definition about supportive activities and the variables influencing the supportive activities, and at suggesting the marketing points of non-profit-making organizations on the base of the model. This is because the concept of service quality about non-profit-making organizations has not been formed yet, and so it does not influence the trust or the satisfaction. Other assumptions seemed to have some relationship. As a result, in order to increase the intent of sustaining support and the trust in organizations, they need to inform supporters of the image or the results of activities by means of active marketing activities.

The purpose of this study is to empirically examines the effects of corporate sustainable management activities(social activity, economic activity, environmental activity) on the innovation activities(managerial innovation, technical innovation) in the convergence era. To accomplish these purposes, their relationships were modeled based on the previous studies conducted in the various areas. A total of 500 questionnaires were distributed to the employees working at the small & medium size companies. The statistical techniques such as descriptive analysis, reliability analysis, factor analysis, correlation analysis, multi regression analysis were used to evaluate the research model. The results of multi regression analysis show that all three aspects of corporate sustainable management activities have positively significant effects on the two factors of innovation. That is, if each activities of sustainable management works properly, it leads to create innovation. In addition, enterprises are needed to develop training programs or action planning that make the employees understands sustainable management well. Thus, the advanced level of corporate sustainability is expected if various sustainable management activities are performed in harmony with their innovation activities.
