This study was carried out to evaluate mechanical properties of the jointed Al6061/HT590 alloys by friction stir welding (FSW). FSW was conducted under the conditions with tool rotating speed of 500 RPM and traveling speed of 300 mm/min., where Ar gas was introduced to prevent the materials from corrosion during the welding process. Electron back-scattering diffraction (EBSD) was used to characterize microstructures such as grain size, misorientation angle and crystal orientation. Evolution of intermetallic compounds in Al6061 during the process were examined in terms of morphology, size and aspect ratio at three distinct zones Al base material, heat affected zone and stir zone, where transmission electron microscope (TEM) was used. It was revealed that FSW gave rise to refinement of grains as well as growth of intermetallic compounds in Al6061. The morphological changes of intermetallic compounds exerted an influence on mechanical properties, resulting in occurrence of fracture in the part of the base material instead of the jointed parts (heat affected zone and stir zone). This study systematically evaluated the microstructural evolutions during the FSW for joining Al6061 with HT590 and their effect on mechanical properties.

Objectives: The purpose of this study was to examine the mediating effect of human rights consciousness on the relationship between social capital and eudaimonia perceived by adolescents. Methods: The participants of this study were 9,021 adolescents, with data taken from the 6^th year(2018) panel survey. All variables were evaluated by self-report of adolescents. The data were analyzed by SPSS 21.0 and AMOS 21.0. Results: First, social capital perceived by adolescents had a direct effect on eudaimonia. Second, social capital perceived by adolescents had an indirect effect on the eudaimonia through human rights consciousness. Conclusions: This study highlighted that human rights consciousness was identified as important mediator in the relationship between capital perceived by adolescents and eudaimonia. These results can be used as an important contribution to further research and educational practices for promoting the eudaimonia in adolescents.

This study was carried out to evaluate the developed microstructures and mechanical properties of friction welded A6063 alloy. For this work, specimens were prepared at a size of 12 mm ${\O}{\times}80mm$, and friction welding was carried out at a rotation speed of 2,000 RPM, friction pressure of $12kgf/cm^2$ and upset pressure of $25kgf/cm^2$. To perform an analysis of the grain boundary characteristic distributions, such as the grain size, orientation and misorientation angle distributions, the electron back-scattering diffraction method was used. In addition, in order to identify the dispersed intermetallic compounds of the base and welded materials, transmission electron microscopy was used. The experimental results found that the application of friction welding on A6063 led to significant grain refinement of the welded zone relative to that of the base material. Besides this, intermetallic compounds such as AlMnSi and $Al_2Cu$ were found to be dispersed with more refined size relative to that of the base material. This formation retains the mechanical properties of the welds, which results in the fracture aspect at the base material zone. Therefore, based on the developed microstructures and mechanical properties, the application of friction welding on A6063 could be used to obtain a sound weld zone.

Objective: This study was aimed to report the therapeutic effects of herbal medicine on chemotherapy-induced peripheral neuropathy (CIPN). Methods: The prior studies were searched from the databases included PubMed, Cochrane Library, EMBASE, CNKi, CiNii, KISS, NDSL, KMBASE, and OASIS until September 2020. The main search keywords were chemotherapy, peripheral neuropathy, and herbal medicine, and only randomized controlled trials that analyzed the therapeutic efficacy of herbal medicine were included. The Cochrane's Risk of Bias was used for assessment of the risk of bias and the Review Manager 5.3 program was used for meta-analysis. Meta-analyses were grouped by the administration routes of herbal medicines (oral administration or topical use). Results: Nine studies with a total of 563 participants were included. Compared with usual care, the effective rate was higher in oral administrated herbal medicine (RR 1.67, 95% CI 1.25 to 2.23; p<0.001, I2=31%). In addition, topical herbal medicine showed an significantly higher effective rate than placebo (RR 2.20, 95% CI 1.52 to 3.18; p<0.001, I2=0%) and usual care (RR 2.24, 95% CI 1.74 to 2.89; p<0.001, I2=66%). There was no severe adverse effect in all participants. Conclusions: Herbal medicine appears to improve neuropathy caused by chemotherapy in cancer patients more than conventional therapy of CIPN. However, as there is heterogeneity between the included studies and a lack of blinding, further well-designed researches are more needed.

Objectives: This study was aimed to report a patient with metastatic pancreatic cancer treated with modified Bangam-tang and Gunchil-dan in conjunction with gemcitabine. There were better survival-related outcomes compared to gemcitabine alone. Methods: The patient with metastatic pancreatic cancer received gemcitabine as palliative chemotherapy since June 2016 concurrent with modified Bangam-tang and Gunchil-dan since October 2016 to October 2017. To evaluate the effect of treatment, tumor markers (carbohydrate antigen 19-9 (CA19-9) and carcinoembryonic antigen (CEA)), Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1, and overall survival were checked. Adverse events were evaluated according to the Common Terminology Criteria for Adverse Events (CTCAE) version 5.0. Results: After 12 months with the combination treatment, levels of CA19-9 were decreased from 8747 to 265.7 ng/ml and CEA from 42.2 to 6.5 U/ml. Clinical partial response state was shown until May 2, 2017 and stable disease state was maintained from August 4, 2017. In March 2018, the patient got an operation including pancreatectomy and diagnosed with no evidence of disease state in September, 2018. In conclusion, it showed the overall survival of 29 months from June, 2016 to November, 2018. Serious adverse events were not identified. Conclusions: This study suggested that combined treatment with modified Bangam-tang and Gunchil-dan may show better outcome in patient with metastatic pancreatic cancer than gemcitabine alone.

일본 원자력복합체와 토건국가

김은혜(Eun-hye Kim),박배균(Bae-Gyoon Park) 한국환경사회학회 2016 환경사회학연구 ECO Vol.20 No.2

후쿠시마원전사고 이후 5년째인 현재, 일본 정부는 산업 논리와 새 안전 기준을 추가하면서 원전 재가동을 가속화하고 있다. 일본에서 원자력복합체란 원자력 이용과 추진에 대한 이해관계가 상호연계된 관산복합체(GIC)를 지칭한다. 두 번의 원폭 피해의 경험에도 불구하고, 전후 일본은 핵무장을 금욕하는 대신 원전에 막대한 투자를 감행해왔다. 1960-70년대 일본 정부는 지역사회의 저항과 환경운동의 영향으로 원전 입지 선정에서 난관에 봉착했음에도 불구하고, 1970년대부터 1990년대 중반까지 매년 평균 1.5기의 원자로를 건설하였다. 이는 일본의 관료 집단과 경제계가 1970년대 두 번의 오일 쇼크를 경험하면서, 석유에 대한 대체에너지를 찾는 과정이었다. 그러나 이러한 경제사적인 주장에 대해서 비판적 학자들은 원자력산업의 확대를 둘러싸고 이해관계를 공유하는 원자력복합체가 일본 원전 확대의 배후에 있다고 지적한다. 일본의 원전은 발전과 송전이 일체화된 지역 독점 시스템 속에서 전개되었다. 원전 입지 지자체에 대해 총괄원가방식의 전기요금에 기초한 전원3법 교부금을 배분하는 토건국가적 시스템을 구축해왔다. 후쿠시마 사고 이후 원자력시민위원회를 중심으로 하는 일본의 시민사회가 원전제로사회로 가자는 대안을 제시하고 있지만, 이를 위해서는 원자력복합체를 중심으로 형성된 기존 에너지 체제의 경로의존성을 극복하는 것이 중요한 과제이다. Japanese Government has recently restarted the operation of nuclear plants in five years after the Fukushima nuclear disaster, on the basis of the following reasons; 1) the importance of industrial development and 2) the imposition of stricter safety standards. The nuclear industrial complex, a public-private coalition operating on the basis of the mutual connections for common interests on the use and propulsion of nuclear plant, has been formed in Japan. Even though having restricted the nuclear armament in the postwar period due to its negative experiences with atomic bombs in the WWII, the Japanese government has been very active in the economic utilization of nuclear power, thereby being actively engaged with the development of nuclear power plants. It established 1.5 power reactors per year from the 1970s to the mid-1990s, which was exceptionally high compared to other countries in the world. While the government officials and many economists have advocated the expansion of nuclear power plants in terms of the efforts needed to overcome two oil shocks in the 1970s, the development of nuclear power plants has been, in fact, promoted more on the basis of the Japanese government’s goal attainment approach rather than economic rationality. Under the influences of the nuclear industrial complex, the Japanese government has put excessive emphases on the development of nuclear plants, thereby strengthening the aspects of the construction state through its financial subsidies given to local government as a compensation for the location of nuclear power plants in their localities. The electronic system in Japan has been operated by local monopoly, the unity of power generation-transmission, the cost of site distributed by Three Laws for Power Plant Siting, of which the electric charges were made on the basis of the Fully Distributed Cost Method. After the Fukushima disaster, the Japanese civil organizations, like ‘Citizens’ Commission on Nuclear Energy (CCNE)’, have proposed alternative thoughts on energy system, like a “Nuclear-Free Society”, the pro-nuclear power plant policies have been re-established in Japan due to the path-dependent influences of the nuclear industrial complex.

기후, 피부색 그리고 인종차별:『검은 가면극』과 『오셀로』를 중심으로

김은혜(Eun-Hye Kim) 한국셰익스피어학회 2021 셰익스피어 비평 Vol.57 No.2

The logic of climate-body-skin color, which has been deeply rooted in Western history, is well reflected in Renaissance dramas. This is called "geohumoralism" and it has inner contradictions of fixity and variability for human body. It was used as a propaganda to build Englishness and British Empire in the early modern era. This proves that the racial theory and the concept of racism based on the land-body had already been established logically and politically before the modern race theory appeared. Especially, as the first masquerade of the Stuart Dynasty, Ben Jonson’s The Masque of Blackness tries to offset the hybrid image of King James as a foreigner, and also makes the change of skin color as an imperialist propaganda as a theme. In order to step up into the Great Britain Empire, England was at the moment to establish its identity and thus set Africa as ‘the Other’ to establish its own self. However, Shakespeare’s Othello reveals how obscure the propaganda is and investigates deeply the fact that Moors can not be accepted in a white society. Although Shakespeare shows the holy love between Desdemona and Othello, Iago finally makes Othello ever-changing Moor who is defined by white imperialists. In this respect, these two works thoroughly debunk the English double-sided vision on Africa.
