Rise of China has correspondingly seen increased Chinese involvement at global stage and regional levels in different parts of the world. This has attracted claims of strategic competition and rivalry between China and U.S., as China is said to be working towards replacing hitherto U.S. influence. Consequently there have been calls for U.S. to counter increased Chinese involvement to safeguard U.S. influences and interests. This study aims to contribute to this debate by examining the extent to which increased Chinese involvement in Africa has, if any, supplanted U.S. strategic interests in the continent. The study contends that, Chinese involvement in Africa has entailed China creating own niche that does not necessary threaten U.S. interests in the continent as widely portrayed and imagined. This is premised on the fact that, U.S. has historically had relatively minimal strategic interests in Africa as compared to other more strategic parts of the world that China could significantly threaten. Seen in this way, increased Chinese penetration in Africa has not had immediate threats to U.S. core strategic interests, thus explaining U.S. measured response to counter Chinese presence in Africa.

Abusive supervision occurs in a social context in which third-party observers react and interact with the abused victims and supervisors. Despite the importance of third-party observers' behavior in abusive supervision, research on abusive supervision has mainly focused on the dyadic relationship between direct victims and supervisors. Although in recent years research on third parties' reactions to peer abusive supervision has attracted growing attention, there are still insufficient studies examining the topic especially within domestic research in Korea. As such, this study comprehensively reviews empirical studies on third parties' reactions to peer abusive supervision and aims to broaden the scope of research in the field. Firstly, the results of previous studies show that the effects of observed peer abusive supervision are mediated by cognitive and affective processes. Secondly, previous studies are found to investigate the boundary conditions where the effects of observed peer abusive supervision can be amplified or mitigated with regard to various outcomes. Overall, compared to research on direct victims, research on third-party observers of abusive supervision is found to capture a wider spectrum of responses. In order to explain the mechanisms of this phenomena, this study thoroughly examines theoretical assumptions presented in previous studies and categorizes them into five theory types. Finally, this study identifies a couple of central methodological issues, including common method bias and inadequate model specification in the literature and suggests future research directions.

우리 사회가 발전함에 따라 재해의 위험으로부터도 안전하게 살고자 하는 대중들의 욕구 또한 증가하고 있다. 하지만 최근의 기후변화와 이상홍수의 사례에서 볼 때 현재 우리가 처해 있는 자연재해로부터의 위협은 과거와는 상이하다는 것을 알 수 있다. 이러한 위협에 대처하기 위해서는 우리에게 노출된 재해의 특성을 평가하는 과정이 무엇보다 선행되어져야 한다. 홍수로 인한 피해는 대부분이 인명이나 재산피해가 주를 이루기 때문에 홍수위험도의 평가결과도 발생 가능한 인명이나 재산피해로 표현되는 것이 적절하다고 판단된다. 따라서 본 연구에서는 지역회귀분석을 적용하여 가능 홍수 피해금액을 추산하고, 이를 통해 각 지역별 홍수위험도를 평가하는 방법을 제안하였다. 지역회귀분석은 강우유출모형이나 확률분포모형의 매개변수들을 유역 특성인자들로 표현하기 위해 수문학 분야에서 사용되어져 왔으며 본 연구에서는 이 방법을 홍수 피해금액 추정에 응용하였다. 지역회귀방법의 절차는 먼저 계측지역에서는 홍수 피해금액과 시강우량 자료를 바탕으로 비선형회귀분석을 실시한 후 이 회귀식의 계수를 다시 해당 지역의 인문 사회 경제학적 인자들로 표현하였다. 이러한 방법을 통해 지역적 인자들이 홍수 피해에 미치는 영향을 정량적으로 분석할 수 있었으며 궁극적으로 미계측지역에서도 지역적 인자들을 통해 특정 빈도에 발생 가능한 홍수 피해금액을 추정할 수 있었다. 최종적으로 추정된 홍수 피해금액과 지역 총 자산의 비를 통해 홍수위험지도를 작성하였다. 본 연구결과를 수자원장기종합계획에서 홍수위험도 평가를 위해 사용된 홍수피해잠재능(Potential Flood Damage; PFD)과 비교해 보면 PFD에서는 각 인자들의 가중치 산정에서 전문가의 주관이 개입될 수 있다는 단점이 있었으나 과거 피해금액과의 상관관계를 분석한 본 연구에서는 이러한 단점을 극복할 수 있었다.

The single and the married couples elderly are rapidly increasing in the next twenty years. Due to the size of these group, their level of living, life satisfaction, income and medical security and welfare services utilization have been a social issue in Korea. For these reasons, the purpose of this study was to analyze the determinants of welfare services utilization by the single and the married couples elderly. Their analyses were composed of a cross-tabulations and t-test, analysis of variance, duncan test, multiple regression analysis using 5'th Wave Korea Welfare Panel(2010). Data were collected from a survey of 2,716. The results showed that the elderly single women had the lowest level of income and health, the elderly single men needed the help about the emotional support for improvement of family and social relations. The married couples elderly are young and the participation rate of job opportunities for the elderly is high, relatively. The results of the multiple regression analysis indicated that the level of income and medical security and the satisfaction of family relationships were important factors as related to the welfare services utilization.

금형공장의 생산 일정관리에 있어서 실제 가공작업에 대한 실적데이터의 집계는 매우 중요하지만, 이러한 작업상황을 기록하는 것에 대해서 현장 작업자는 비협조적이고 반감을 갖고 있는 실정이다. 현장에서는 작업자의 개입없이 CNC 장비의 컨트롤러와의 직접적인 인터페이스를 통해서 신호를 추출하고 자동으로 작업상황을 파악할 수 있는 시스템을 구축하려고 시도하고 있지만, 컨트롤러 메이커마다 다르게 적용해야 하고 많은 비용을 요구한다. 이러한 이유로 본 연구에서는 저가의 PC 카메라를 장비에 설치하여 가공상황에 대한 동영상을 수집하고 영상처리 알고리즘을 적용하여 가공시간을 집계하는 방법을 제안한다. 제안된 방법은 CNC 컨트롤러에 독립적으로 운용되며 저렴하게 시스템을 구축할 수 있는 장점이 있다. 본 연구에서는 무인가공과 유인가공 상황에 시범적으로 적용 및 운영함으로써 시스템의 활용가능성을 살펴보았다.

Depression in old age not only is prevalent but also causes a considerable amount of burden in physical, psychosocial, and economic terms. Intervention, however, is often delayed due to the understanding that considers depressive symptoms as a normal process of aging or signs of physical illnesses. Since the recognition of symptoms often initiate one's help seeking process, a correct identification of symptoms can contribute to early detection and intervention to depression in oneself as well as in others. This study interviewed 104 older adults living in an urban area, and explored their ability to correctly identify depressive symptoms and factors related to identification. The study results show that respondents who were able to correctly identify symptoms of depression were only 14%, and the rest defined the symptoms as social, economic, and other psychological issues. Of the factors in the logistic regression model, age being 75 and over and mass media as source of mental health information affected negatively their ability to correctly identify symptoms; mental health education programs affected positively their ability. Based on these results, it is suggested that such strategies as employing a face-to-face provision of concrete information and counseling can be more effective than delivering information via large-scale lectures. Additionally, a future research deems necessary to conduct an in-depth examination of mental health/illness-related contents on mass media.

Older adults in the hospice care experience difficulties in expressing their emotional and psychological issues, which has detrimental effect in their well-being. The purpose of this study is to examine how music can be used to facilitate self-expression both verbally and nonverbally in order to decrease negative influences of self-concealment. Four cases were referred from hospice personnel at the hospital, and received music therapy sessions for four month. The total number of session varied from 9 to 11 depending on the conditions of each case. Both qualitative and quantitative data were collected from pre and post test of Self-Concealment Scale and Personal Descriptive Essays. The results indicated that the use of music, especially programed songs were effective in evoking emotional responses with various life-related issues and themes. The posttest indicated that the level of self-concealment has decreased, and also the Personal Descriptive Essays involved increased statements of emotional content after music therapy implementation. The study indicates that music can be used as an significant communicative and expressive medium when working with older adults in the hospice or palliative care, since they experience many difficulties to be engaged in the active expression. Music provide both passive and active experience through listening and participating, and programed music therapy intervention will increase the quality of life through expressive music activities.

The purpose of this study was to investigate the effects of childhood obesity on school adjustment and whether the effects were mediated by withdrawal. Using the 2015 Korea Welfare Panel Study data, this study conducted a hierarchical regression analysis to examine the mediating effects of withdrawal on the relationship between childhood obesity and school adjustment. In addition, a Sobel test was used to consider the statistical significance of the mediating effects. Findings were as follows: First, childhood obesity had a negative influence on school adjustment. Second, childhood obesity affected withdrawal positively. Third. withdrawal had a negative impact on school adjustment. Fourth, withdrawal was found to partially mediate the relationship between childhood obesity and school adjustment. Based on the results, implications were discussed to intervene in preventing childhood obesity and to reduce the negative effects of childhood obesity.
