Graphene oxide (GO) and ultrafine slag (UFS) have been applied to reinforce cement mortar cubes (CMC) in this research. The consequences of GO and UFS on the mechanical attributes of the CMC were explored through experimental investigations. Established on the results, at the 28 days of hydration, the CMC compressive and flexural strength with 0.03% of GO and 10% UFS were 89.8 N/mm2 and 9.1 N/mm2, respectively. Furthermore, the structural changes of CMC with GO and UFS were qualitatively analysed with instrumental techniques such as scanning electron microscope (SEM), X-ray fluorescence (XRF), thermogravimetric analysis (TGA), Fourier transform infrared spectroscopy (FT-IR), FT Raman spectroscopy, atomic force microscopy (AFM), and 27Al, 29Si-Nuclear magnetic resonance spectroscopy (NMR). SEM results reported that GO and UFS formed an aggregated nanostructure that improved the microstructural properties of the CMC. TGA analysis revealed the quantum of calcium hydrate and bound water accomplished by supplementing GO bound to the UFS aggregates. FT-IR analysis of the CMC samples confirmed the ‘O-’comprising functional groups of GO which expedited the formation of complexes between calcium carbonate ( CaCO3) and UFS. 0.03% GO was the optimum dosage that enhanced the compressive and flexural attributes when combined with 10% UFS in CMC.

With the rapid development of flexible wearable electronic products, flexible all graphene-based supercapacitors (FGSCs) with reduced graphene oxide rGO//graphene oxide (GO)//rGO structure have attracted substantial attention due to their unique structures and energy storage mechanism. However, restricted by design idea and preparation technology, improvement of capacitance performance for the FGSCs is not obvious recently. Herein, we demonstrate that an interface integration strategy of constructing the high-performance FGSCs with compact structure. Hydroquinone (HQ)-modified rGO (HQ-rGO) films (electrode materials) and sulfuric acid-intercalated GO films (electrolyte/separator) are assembled into the FGSCs utilizing hydrogen bonding and capillary contractility. The HQ further improves the electrochemical capacitance of electrode materials. The synergistic effect of the hydrogen bonding and capillary contractility guarantees compact and stable structure of the device. The resulting FGSCs exhibit an excellent areal capacitance of 804.6 mF cm− 2 (@2 mA cm− 2) and 441 mF cm− 2 (@30 mA cm− 2), and their highest energy and power densities can achieve 109.5 μWh cm− 2 and 21,060 μW cm− 2, respectively. These performances are superior to other all-in-one graphene-based SCs reported. Therefore, the construction technology of the FGSCs is a promising for developing all graphene-based SCs with high-performance.

This study aims to restore the dignity of the elderly based on “filial piety” and community values in preparation for the 'silver tsunami' in Jeju by studying the case of Whitney Center in the United States, PASSi, Jeju's Isidol Nursing Home, and the haenyeo society. The main goal was to develop the Asian Jeong Nang model which was named by professor Koh Chang Hoon, Chair of Island Research Institute at Jeju National university. Jeong Nang(정낭) is the gateway with 3 wooden bars to the traditional residential space of Jeju where several generations live together. Dr. Hesung Chun Koh, Chair of East Rock Institute gave me motivation and support for the study of the elderly welfare model at the Jeju National University Island Research Institute. As the head of this study, I was dispatched from the Jeju National University Island Research Institute to the East Rock Institute (ERI). Dr. Hesung Chun Koh, M.D. Ann Datunashivili who is a practice professor at Medical School of Yale and in charge of Medical Center of Whitney Center. and Mike RambaRose who is Chief Executive Officer of Whitney Center, supported my research. In addition ImJa Choi, CEO of PASSi, also allowed two research students, Lee Seung Yong and Ko Yu Seok, from Jeju National University, to help my research related to psycho-social approach for the elderly at PASSi. This study was intended to develop a model for senior citizens in Korea through Hesung Chun Koh's ERI CCAI Model, Whitney Center's residential apartment model for retired seniors, and PASSi's community care model for the multi-cultural community.

This study were performed in Tropical Plant Resources Research Center of Korea National Arboretum, Pocheon, Korea to assess the effects of beneficial insects against Pseudococcus comstocki (Kuwana) on Phyllanthus acidus (Linnaeus) Skeels and Tetranychus urticae Koch on Acalypha wilkesiana Muell Arg. We investigated the density of leaf-feeding P. comstocki at intervals of approximately 2 weeks and T. urticae at intervals of approximately 1 weeks after introducing their natural enemies; Chrysoperla nipponensis (Okamoto) and Phytoseiulus persimilis Athias-Henriot. The densities of P. comstocki were suppressed 80.0% (after 4 weeks) and 97.5% (after 8 weeks) after introducing C. nipponensis. The densities of T. urticae were suppressed 84.1% (after 4 weeks) and 99.6% (after 6 weeks) after introducing P. persimilis.

우리나라는 1953년 창경호(사망 300여명)을 시작으로 1970년 남영호(사망 326명), 1993년 서해훼리호(292명), 2014년 세월호(사망 295명, 실종 9명) 사고가 발생했다. 반복되는 대형 해양사고에도 불구하고 정부나 국민의 안전의식은 여전히 저조한 실정이다. 이 연구는 국민들의 안전의식 고취를 위해 해양안전체험장의 도입과 대형 해양사고 발생 시 수색ㆍ구조 기관에 신속히 자문해 줄 수 있는 안전연구센터의 설립의 필요성에 대해 제안한다.

본 연구의 목적은 주․야간보호 종사자 처우와 개선방안에 대하여 본 연구를 통해 논의와 제언을 제시하였다. 인터뷰는 주․야간보호센터 4개소에서 인터뷰를 진행하였으며, 시설장 4명, 실무자 4명에 대해서 동일한 질문을 내용으로 면접 인터뷰를 진행하였다. 4개소의 시설은 사회복지법인 2개소, 개인시설 2개소로 진행하였으며, 4개소 모두 운영방식 및 종사자 처우의 차이점에 대해서 분석하고 확인하였다. 인터뷰 결과로 전체의 주․야간보호 시설을 대변할 수 있는 내용은 아니지만 노인장기요양기관과 사회복지시설이라는 동일성과 전국이 동일한 주․야간보호 급여 이용수가 운영체제라는 점을 고려했을 때, 운영주최의 특성에 따라, 혹은 시설장이나 대표에 따라서 운영방식과 종사자 처우가 상당부분 다른 점을 확인할 수 있었다. 복지관 부설 주․야간보호의 법인 시설의 경우 지자체 보조금 및 법인 지원금으로 재가노인복지시설 인건비 가이드라인을 유지하였으며, 복지관 종사자 처우를 2014년 사회복지관·노인복지관 직원 기본급 권고 기준(사회복지직)과 사회복지이용시설(복지관) 종사자 수당 기준에 준하는 급여를 연봉제로 전환하여 지원하고 있음을 확인하였으며, 그로 인한 종사자 처우 등으로 인한 직무만족이 높음을 확인하였다.또한 높은 직무만족이 클라이언트에게 직접적으로 전하는 서비스 질에 영향을 미치고, 만족도가 상향된다는 것을 종사자 인터뷰와 연구조사 및 결과로 확인하였다. 아울러, 인터뷰와 사전자료를 통하여 종사자 직무만족 수준과 종사자 처우와 개선방안을 제시하였다.

In this study, actual status of safety management for the objects of 173 university, government research institution, and corporate affiliated research center was carried out through questionnaires. For unexpected accident status according to kinds, scale, and types of laboratories, frequency analysis using cross analysis and multiple replies analysis was used. The result of this study is judged to be used for laboratory safety education prevention programs, laboratory environment improvement, investment or improvement of laboratories through the actual safety management status of laboratories such as vulnerable works for generation of unexpected sudden accidents according to kind, scale, and type of laboratories, period of occurrence, prevention education, necessity for preliminary test, and cause of laboratory accidents.

The study on semiconductor industrial accident in korea has been focused on frequencies of each type, employee, characteristics, cause and un-safety condition, behaviour and so on. Those attributes of semiconductor industrial accidents were usually analyzed independently, so that it was hard to provides a well-process and systematic guide lines for efficient safety management. There fore, there were a few studies based on comprehensive survey in terms of sharp-type of safe management. The questionnaire survey carried out for the workers(284) who were responsible for safety management in to center with corporate company with semiconductor industry the factor analysis showed that there were three factor of safety management. They were 1) Investment and operation and management for accident prevention, 2) Unsafe, safety management 3) General human error and behavior the industries of respondents were correlative with three group. Three Groups showed a statistically significant differences on the number of cases. Actually, the group with the larger investment and the better unsafe cause, human error a of accident prevention had a smaller cause of accident cases.

우리나라 상품의 대외경쟁력은 대체적으로 국내 물류비에서 결정된다. 이 좁은 국토(거리상으로)에서 왜 그리도 많은 내륙 물류비를 부담해야 하는 지 많은 이들이 의아해 한다. 제대로 갖추어져 있지 못한 국가차원의 사회간접자본(SOC) 시설, 승용차 중심의 도로운송시스템도 문제지만 제품공장과 수출입관문인 항만.공항간의 연결점에 있는 물류거점시설들이 활성화돼 있지 않다는 것이 요인으로 지적되고 있다. 민간업자 차원에서는 국토 요소요소에 물류센타를 세워놓고 고객들의 화물에 대한 일괄 물류서비스를 제공하려고 많은 노력들을 하고 있다. 이곳에서는 보관, 재고관리, 유통가공, 보세운송, 수배송, 물류대행, 물류컨설팅 등 종합(통합) 물류서비스들이 이루어진다. 이에 본 연구에서는 이러한 물류센터의 실태를 조사하여 수요에 따른 물류센터의 공급능력을 평가하면서 물류의 일괄서비스 측면에서의 효율성을 점검해 보고져 한다. 또한 향후 이 분야에 있는 연구나 조사 필요성이 있는 과제가 무엇인지를 검토하여 단계별 연구과제를 정의하여 체계적인 연구가 진행될 수 있도록 하는데 그 믿걸음이 되고져 한다.
