이중편파 강우레이더는 차등반사도, 차등위상차, 비차등위상차 등 다양한 변수를 관측하여 호우의 공간적 규모, 호우를 구성하는 강수입자, 호우의 이동방향 등 종합적인 강우 정보를 제공한다. 이러한 이중편파레이더를 이용하면 단일편파레이더에 비해 보다 정량적인 강수 추정이 가능하다. 일반적으로 이중편파 강우레이더의 강우추정 관계식은 DSD 및 강우입자 모형을 기반으로 물리적으로 유도된다. 그러나 DSD는 호우 사상에 따라 그 양상이 다르며, 동일 호우 사상 내에서도 시공간적으로 변화가 크다. 이러한 DSD에 내포된 변동성은 결과적으로 레이더 강우에 큰 불확실성을 유발하게 된다. 이에 본 연구에서는 확률대응법을 이용하여 이중편파레이더의 강우추정 관계식을 추정하는 기법을 개발하고자 한다. 확률대응법은 실시간으로 강우추정 관계식의 매개변수를 추정하는 기법으로 단일편파레이더의 Z-R 관계식에 적용된 바 있다. 이러한 확률대응법을 이용하면 시공간적으로 변하는 DSD 등 호우사상의 개별적인 특징을 반영하여 호우사상별 강우추정 관계식의 매개변수를 실시간으로 결정할 수 있다. 따라서 본 연구에서는 이중편파레이더의 강우추정 관계식 중 R(KDP, Zdr), R(Zh, Zdr) 관계식을 위주로 매개변수를 이변량 확률대응법을 통해 추정하고, 기존의 강우추정 알고리즘 및 관계식의 레이더 강우 추정 결과와 비교를 통해 적용성을 평가하였다.

The intergenerational support exchange depends on elder's objective conditions and social context, and its effects are diverse. I argue that not only capacity such as health condition and economic status but also relational properties among parent(s) and adult children are important to determine their reciprocal support exchange. Seoul area is selected, and 730 elders are interviewed to be analyzed quantitatively. The survey data are collected based on the structured questionnaire. Findings are partly supportive to the arguments presented above. The relational properties, especially coresidence, the number of adult children, and contact frequency independently influence reciprocal support. The better health conditions of parent(s) are, the more support to adult children is given. The economic status is related to financial support exchange only. The types of intergenerational support exchange include dependant, balanced, and generalized reciprocity. The most important determinant of the reciprocity is the elders' health condition.

The purpose of this study were to investigate relations among family resilience, self-determination(autonomy, perceived competence, relatedness) and commitment to career choice and to examine the meditating effects of self-determination(autonomy, perceived competence, relatedness) in the process by which family resilience affected commitment to career choice. Subjects of the study were 277 college students in the Chungbuk and Kyungpook province. AMOS 7.0 was employed to analyze the data. The results were as follows: First, college students' family resilience had a direct impact on college students' self-determination(autonomy, perceived competence, relatedness) and commitment to career choice. Second, students' self-determination(autonomy, perceived competence, relatedness) had a direct impact on students' commitment to career choice. Third, it was found students' self-determination(autonomy, perceived competence, relatedness) was a meditating factor in the relationship between students' family resilience, and commitment to career choice.

창업기업의 성과는 창업가 개인의 역량 뿐 만 아니라 네트워크 등 기업가 정신이 발현되는 모든 영역의 요소들이 작용한다. 재무적 자원에서부터 기업의 기능별 역량과 자원에 이르기까지 충분하지 않은 창업기업들은 전략적으로 기업이나 대학과 같은 외부 주체들과의 제휴를 추진하여 성과향상을 의도할 수 있다. 전략적 제휴와 기업 성과 간의 관계는 전략경영분야에서 오랫동안 다루어져 온 연구 주제였다. 다만, 창업기업이라는 한정된 역량과 자원 상황에서 창업 기업이 실제로 이러한 전략적 제휴를 통해 재무성과를 향상시키는지에 대한 연구는 미흡하였다. 이에 본 연구는 창업기업의 전략적 제휴가 재무성과에 미치는 영향을 규명하고 그러한 관계에 영향을 미칠 수 있는 혁신역량 강화활동으로서 R&D투자와 교육훈련 투자의 영향을 분석하고자 한다. 또한, 창업기업이 보유한 인적 여유자원(slack resource)의 역할도 함께 규명하여 창업기업의 전략적 제휴와 관련한 행동적 특성을 논의하고자 한다. 이를 통해 본 연구는 기업이 전략적 제휴를 통해 보다 나은 성과향상을 위한 투자로서 다양한 혁신역량 강화활동 필요성에 대한 시사점을 제시할 것으로 기대한다.

This paper examine the roles of social rapport and friendship which are the representative variables of strong emotional bonds between customers and firms in service relationship marketing. As results, social rapport and friendship were confirmed as positive moderators between a relational antecedent variable and a relational mediator variable. In other words, emotional bonds, such as social rapport and friendship, stimulated relationship development in service relationship marketing. Meanwhile, customer-firm emotional bonds seemed to be a negative effect on the stage of a relational mediator variable and a relational outcome variable. This meant that relational mediator variable and emotional bond variables(social rapport and friendship) individually had an positive effect on a relational outcome variable. If emotional bonds between customers and firms had already built, they could have positive influence on the relational outcome, regardless of relational mediator variables. Conclusively, firms' relational efforts focus on the building the emotional bonds with customers, not on the process of relational antecedents, mediators, and consequences.

For that purpose, 305 4-year university students in G Metropolitan City and J Province were surveyed to rate the parents' psychological control scale, dysfunctional belief, ambivalence over emotional expressiveness, and interpersonal problems. The data were analyzed using SPSS 22.0 and SPSS Macro. As a result, it was found that dysfunctional belief and ambivalence over emotional expressiveness had a mediating effect in the relationship between the parents' psychological control scale and interpersonal problems. Also, dysfunctional belief and ambivalence over emotional expressiveness had a dual mediating effect on the relationship between psychological control scale and interpersonal problems. As a result of testing the significance of the mediating effect through Bootstrapping, dysfunctional belief and ambivalence over emotional expressiveness had a significant dual mediating effect. The purpose of the current study was to establish a useful theoretical foundation for counseling strategies to efficiently help through counseling the university students who are having difficulties with interpersonal relations due to parental control.
