This paper proposes an approach in Southeast Asian studies using a post-colonial framework in the study of post-colonial Southeast Asia. This framework is based on the sociology of knowledge that analyzes the dialectical relationship between science, ideology, and discourse. Post-colonial studies is critical of the concept of universality in science and posits that a scientific statement of a society cannot stand alone, but is made by authors themselves who produce, use, and claim the so-called scientific statement. Several concepts in post-colonial theories can be used to develop area studies, i.e. colonial discourse, subaltern, mimicry, and hybridity. Therefore, this study also explores these concepts to develop a more comprehensive understanding of Southeast Asian culture. The development of post-colonial theories can be used to respond to the hegemony of social theories from Europe and the United States. The main contribution of area studies in the field of the social sciences and humanities is in revealing the hidden interests behind the universal social sciences.

Contact material is widely used in the field of electrical parts. Ag-CdO has a good wear resistance and stable contact resistance. We studied a lifetime of Ag-CdO material because of getting better properties of Ag-CdO using Post-oxidation. The experimental procedure were melting using high frequency induction, heat treatment, rolling and internal oxidation. And we experimented on difference process, Post-oxidaion. Then we tested a lifetime and analysed. We obtained the optimizing oxidation temperature was $750^{\circ}C$. Using Pre-oxidation, coarse oxide and depleted oxidation layer existed but finer oxides were existed and depleted oxidation layer was not using Post-oxidation. In Post-oxidation, The density was 10 $g/cm^{3}$, the hardness was Hv 80 and the adhesive strength was 9000N. The specimen of Post-oxidation had better lifetime properties than that of Pre-oxidation. We predicted that the lifetime of Post-oxidation specimen is more longer twice than that of Pre-oxidation one.

As the smartphone market becomes saturated, an innovative device equipped with new features is expected to appear soon in mobile communications. In particular, various possibilities were raised regarding the alternative technologies that can develop post-smartphones, which are differentiated from the current smartphones, as Korea commercialized the 5G infrastructure for the first time in the world. Under these circumstances, the Korean government announced the "5G+ Strategy for Realizing Innovative Growth" in April 2019, vowing to build an innovative industrial ecosystem quickly while creating various convergence services based on the 5G infrastructure. As described above, the policy importance of the alternative technologies that will develop post-smartphones is increasing, but the theoretical study on the technology evolution of post-smartphones has not been systematically conducted until now. This study reviewed the alternative technologies that can develop post-smartphones through documentary research, and data mining analysis was performed on the research result using actual data. The policy priority was also set quantitatively for the alternative technologies of post-smartphones in order to determine the alternative post-smartphone technology that the government should focus on given the constraint of limited resources. As a results, autonomous vehicle(43.68%) was found to be most important, followed by artificial intelligence(17.4%) and Internet of Things(13.1%), among alternative technologies that could develop into the post-smartphone.

Objectives : The purpose of this study was to identify the post-traumatic stress, social support, and depression of Vietnam veterans and the effects of post-traumatic stress and social support on depression. Methods : This study was carried out from June 2017 to September 2017 with the cooperation of the Korean Society of Veterans' Affairs and 250 Vietnamese veterans from D city were randomly sampled and collected. The collected data were used by SPSS 24.0 Statistics Program. Results : Social support was inversely correlated with post-traumatic stress (r=-.268, p<.001) and depression (r=-.333, p<.001), and post-traumatic stress and depression (r=.592, p<.001) were positively correlated. Post-traumatic stress and social support of veterans had a significant effect on depression, and post-traumatic stress and social support showed an explanatory power of 37.7% in depression. Conclusions : It is necessary to improve soldiers' mental health by mediating their post-traumatic stress and reducing their depression level by establishing a social support system.

This study examines the simultaneous impact of gender and administrative post on the research motivation of university lecturers. There are 475 selected questionnaires that are qualified for data processing and the collected data are analyzed by two-way analysis of variance (ANOVA). The results show the relationship between administration involvement and scientific research of lecturers. In general, lecturers with administrative post have higher research motivation than lecturers without administrative post. More specifically, the level of administrative post has positive correlation with research motivation of female lecturers, but has negative correlation of male lecturers. It means that a female lecturer with higher administrative post also has more motivation to conduct research. Conversely, the higher administrative post a male lecturer has, the less research motivation he is. The cause of this difference is the pressure of earning money on Asian men, including Vietnamese men, who are considered to be main breadwinners of their family. When having an administration post, the more chances male lecturers have to earn money, the less time they can spend for scientific research. This suggests that the solution for managers is to perform annual assessment, fulfill promotion process, build up motivation and reward system, and establish recruitment and promotion policies.

건설공사 사후평가 제도는 공공건설사업 수행결과를 반영하여 향후 유사한 공공건설사업의 계획 수립 시 활용되어져야 하나, 현행 제도는 당초 기획 계획 당시에 추정한 수요, B/C비율, 공사비, 공사기간 등 예측치와 건설공사 완공후 일정기간(3년 내지 5년) 경과후에 측정한 실제 결과치를 단순히 비교하여 제시하는 수준에 그치고 있다. 또한 대부분 공공발주기관에서는 수동적인 사후평가 업무수행에 그치고 있어 제대로 환류가 이루어지않고 있다. 이에 본 연구에서는 공공발주기관을 대상으로 설문조사를 실시하여 건설공사 사후평가 제도의 수행현황을 파악하였으며, 국내 사후평가 제도와 유사한 미국과 일본의 건설사업 평가체계를 벤치마킹하였다. 또한, 건설공사 사후평가 제도와 관련된 국토부 실무담당자와의 수차례 업무회의를 실시하여 사후평가 수행의 적시성 확보 및 활용성 강화방안을 제시하였다. 이와 같이 건설공사 사후평가 제도 개선을 통해 건설사업 수행과정에서의 목표 및 성과에 대한 확인 점검 분석 체계를 내실화하고, 건설공사 특성별로 평가내용 및 방법을 차등화함으로써 발주청의 사후평가 수행에 대한 실천력이 제고될 것으로 기대된다.

2015년 프랑스 파리에서 열릴 UNFCCC 제21차 당사국총회에서는 신기후체제를 위한 합의문인 2015 합의 채택을 목표로 하고 있다. 이러한 상황에서 신기후체제의 설계 특징을 살펴보고 신기후체제 협상에서 가장 중요한 쟁점사항 중 하나인 차별화의 기술적인 적용방법에 대해 논의하였다. 연구 결과 자국이 스스로 정하는 기여(INDC)의 순환적 구조와 감축기여진전 규정을 통해 당사국 스스로 감축상향을 자동적으로 이룰 수 있는 구조로 신기후체제가 설계되어 있는 것이 특징이다. 또한, 이원화된 차별화 적용 방안은 신기후체제에서는 우리나라가 감축과 이행수단 지원 의무국으로 편입될 가능성이 높기 때문에 지양하는 것이 바람직하며 새로운 차별화 적용 방안을 지지하는 것이 필요하다고 판단된다. 차별화의 적용은 INDC와 기본개념을 같이 하는 자체적 차별화가 우리나라의 국익에 부합하며 자체적 차별화를 추진하기 위해서는 이와 관련된 기본 규칙 마련이 필요하고, 기본 규칙은 감축상향을 유도할 수 있도록 설계되어야 한다.

The vibration characteristics of post-buckled laminated composite doubly curved shells are investigated. The finite element method is used for the analysis of post-buckling and free vibration of post-buckled laminated shells. The geometric non-linear finite element model includes the general non-linear terms in the strain-displacement relationships. The shell geometry used in the present formulation is derived using an orthogonal curvilinear coordinate system. Based on the principle of virtual work the non-linear finite element equations are derived. Arc-length method is implemented to capture the load-displacement equilibrium curve. The vibration characteristics of post-buckled shell are performed using tangent stiffness obtained from the converged deflection. The code is first validated and then employed to generate numerical results. Parametric studies are performed to analyze the snapping and vibration characteristics. The relationship between loads and fundamental frequencies and between loads and the corresponding displacements are determined for various parameters such as thickness ratio and shallowness.
