Purpose: The bone defects that are associated with shoulder anterior instability may be the causes of failure of arthroscopic surgery. For the treatment of traumatic shoulder instability, we tried to determine the arthroscopic techniques that can be used for the bone defect of the glenoid and the humeral head. The purpose of this study is to assess the surgical techniques for the arthroscopic reconstruction of the shoulder with anterior instability and bone defects. Materials and Methods: We analyzed the articles that have been recently published on anterior shoulder instability and we assessed the arthroscopic surgical techniques. We compared the articles and the methods of arthroscopic surgical techniques for treating bone defects of the anteroinferior glenoid and the posterolateral humeral head, which were considered as the causes of recurrence of shoulder instability. Results: There are the anteroinferior bone defects of the glenoid and Hill-Sachs lesions in the bone defects that appear in patients with anterior shoulder instability. These bone defects are currently the causes of failure of arthroscopic surgery. Conclusion: Open shoulder surgery may be the treatment of the choice for a shoulder with instability and significant bone defects of the glenoid and the humeral head. But efforts are being made to overcome the weaknesses of open surgery by the use of arthroscopy.

본 연구는 개발도상국에서의 출산력 변천과 그 결정요인을 검토하는데 그 목적이 있다. 구체적으로 본 연구는 출산력 감소의 속도와 인구변천 단계에서의 출산력 변화, 그리고 인구변천 후기에 출산력 수준에 영향을 주는 요인들에 초점을 맞추고자 한다. 이를 위해 본 연구는 우선 지난 40년간 개발도상국에서의 출산력 변화 추이를 검토하고자 한다. 그 다음으로 본 연구는 이러한 인구변천 과정을 사회경제적 변화에 관련시켜 분석하고자 한다. 분석 결과 사회경제 지표들과 영아사망률 및 출산력과의 관계는 대부분 예상했던 방향으로 나타나고 있으나, 그 관계의 통계적 유의성은 조사 시기에 따라 약간의 차이를 보이고 있다. 사회경제적 지표 중 문맹률은 조사 시기에 관계없이 모두 출산력과 통계적으로 유의미한 관계를 보이고 있어, 교육수준이 높을수록 출산력이 낮아진다는 일반적인 견해를 뒷받침하고 있다. 그러나 도시화율과 소득이 각각 출산력에 미치는 영향은 시기에 따라 통계적인 유의성을 달리 하고 있다. 연구 모형에서 중요한 매개변인으로 설정된 영아사망률은 출산력에 가장 큰 영향을 미치고 있는 것으로 나타나고 있으며, 사회경제적 변인들이 영아사망률을 통하여 출산력에 미치는 간접적인 영향도 비교적 잘 드러나고 있다.

This study selects political and military decision factors of Participatory Government's Wartime Operational Control(OPCON) Transition and analyzes, both quantitatively and qualitatively, the effects and relations between those factors. Previous research utilizing the Analytic Hierarchy Process(AHP) selected their decision factors based on academic data and field experience, requiring more objective analysis of the factors. For this study, we conducted a survey among security subject matter experts(SME) both online and offline. The results show that OPCON transition's decision factors were to 'recover military sovereignty', 'set the conditions for peaceful reunification' and 'improve ROK image through enhancing national power' which differs little from the previous AHP method studies. It also showed that 'recover military sovereignty' and 'set the conditions for peaceful reunification' had no relationship to each other and that the key factor that decided the OPCON Transition was actually 'recover military sovereignty' which represents the interest of the liberal party in ROK. This study finds its meaning by analyzing the decision factors of Participartory Government's OPCON Transition thorugh Delphi and DEMATEL method.

The purpose of this study is to understand the effects of adolescents' emotional control strategies on emotional instability and stress. Study subjects included 124 adolescents from Ulsan city. Frequency analysis, reliability analysis, and correlation analysis were performed using the SPSS 22.0 program, and multiple regression analysis was performed on the causal relationships between variables. First, as a result of examining the effect of adolescents' emotion control strategies on job burnout, it was found that emotion-centered strategy, a sub-factor of emotion control strategy, had a significant effect on emotional instability. On the other hand, it was found that cognitive-oriented strategy factors did not significantly affect emotional instability. Second, as a result of examining the effect of emotion control strategies on stress, it was found that emotion-centered strategies, a sub-factor of emotion control strategy, had a significant negative (-) effect on stress. On the other hand, it was found that cognitive-oriented strategy factors did not significantly affect stress. These results imply that higher emotion-centered strategies lead to lower emotional instability and stress. This study provides basic data for preparing plans to reduce the emotional instability and stress of adolescents.

The purpose of this study is to distinguish industrial clusters in Korea. Based on I/O table in 2000, coefficient matrix was calculated and factor analysis was performed on the matrix. Among 38 derived industrial clusters, 5 of them were unreported clusters, which were indistinguishable. Once these 38 industrial clusters were differentiated according to I/O table, final results of clusters were produced as I/O table was converted into KSIC (Korean Standard Industry Code). Since existing studies on industrial cluster have been focused on qualitative methods such as case studies and interviews, it is expected that this study could contribute to carry out more systematic and efficient methodology.
