김하림 ( Kim¸ Ha Lim ),이승익 ( Lee¸ Seung Ik ) 한국기초조형학회 2021 기초조형학연구 Vol.22 No.5

현대사회는 비약적 경쟁 성장이 일으킨 환경 파괴로 전 지구적인 환경 문제에 봉착했다. 패션업계도 지속가능성을 키워드로 개발을 추진하며 환경과 경제적· 사회적 책임의 중요성을 강조하게 되었다. 이 같은 흐름에 따라 디자이너에게도 환경, 윤리, 사회적 책무를 요구하고 있다. 본 연구는 패션 기업과 디자이너들이 실무에 확대 적용할 수 있는 발전 방향을 모색하고, 디자인 연구자에게 환경친화적 패션디자인을 위한 이론적· 과학적 기초 자료를 제공하기 위해 진행되었다. 연구방법은 패션디자인의 지속 가능성에 대한 창의적 아이디어를 도출할 수 있게 하는 기술 융합적 접근 사례를 선정하고 분석하였다. 소재에 대한 기술 융합적 접근은 더욱 정교하고 다양한 측면의 통합적 고려를 할 수 있다는 점에서 환경에 대한 본질적 문제로 접근할 수 있게 한다. 이는 단지 시각적인 친환경 표현의 수준성을 넘어 환경친화적 품질을 지향하는 패션디자인으로 발전하게 하는 것이다. 분석방법은 친환경 염색 기술을 활용한 패션디자인, 소재를 자연 채취하여 무해성을 강조한 패션디자인, 버려지는 폐원단의 최소화에 초점한 패션디자인으로 분류하여 분석하고 논의하였다. 이 같은 고찰을 통해 사례가 보여주는 효과성과 한계점을 짚어보고 앞으로 나아가야 할 방향을 살펴봄으로써 패션 기업과 디자이너들이 실무에 확대 적용할 수 있는 발전 방향을 모색하였다. 본 연구는 패션디자인 영역에서 전반적으로 중요시하는 미적 가치, 유행 창출에만 국한하지 않고, 디자이너로 하여금 친환경성과 지속가능성에 대한 인식을 고취하고 패션산업에서의 혁신적 기술 융합이 현 시대의 문제점들을 해결할 수 있는 방안이 될 수 있음을 살펴보았다. 그러나 대부분의 사례는 아직 실험적 프로토타입 단계에 머물러 있으며 시장성을 갖추지 못하고 있으므로, 앞으로 상업화할 수 있는 심층적 후속 연구를 해야 한다. 본 연구가 환경친화적 패션디자인 시도의 실용화를 촉구하는 계기로 작용하기를 기대하며 패션디자이너들에게 친환경적 소재 개발과 미래지향적 기술 융합의 내재된 가치를 중심으로 발전된 기술에 대한 연구를 기대한다.

Binarwan Halim,Hilma Putri Lubis 대한산부인과학회 2022 Obstetrics & Gynecology Science Vol.65 No.2

ObjectiveThe objective of this study was to evaluate the effectiveness of dual trigger, which is a combination of gonadotropinreleasingagonist (GnRH-a) and recombinant human chorionic gonadotropin (hCG) in the final oocyte maturation, inthe outcome of intrauterine insemination (IUI). MethodsThis retrospective observational study was conducted from January 2016 to October 2018 and involved 639 IUI cyclesat the Halim Fertility Center, Indonesia. Controlled ovarian stimulation was performed during IUI cycles. The ovulationtriggers were divided into two groups: group I received a combination of GnRH-a and recombinant hCG as a dualtrigger, and group II received only recombinant hCG as a single trigger. The baseline characteristics, cycle parameters,and IUI outcomes of both groups were compared. ResultsOur study included a total of 639 IUI cycles, 334 were in the dual trigger group and 305 in the single trigger group. The clinical pregnancy rates were significantly higher in the dual trigger group than in the single trigger group(P<0.001). Based on the multivariate analysis, the dual trigger increased the clinical pregnancy rate by 2.524 timesthan that by the single trigger. ConclusionOur data showed that the dual trigger combination of GnRH-a and recombinant hCG significantly improves theoutcome of intrauterine insemination.

Policy analysis frameworks: A phenomenological study of education policy researchers’ practices

Halime Ozturk-Calikoglu,Osman Cekic 한국교육개발원 2021 KEDI Journal of Educational Policy Vol.18 No.1

Aiming to broaden the discourse on methodology in education policy analysis, this phenomenological study explores the real-life experiences of policy researchers and the methodology they follow in their studies. Eleven senior policy researchers holding both liberal and critical political views of education were interviewed about their approaches beginning from defining a policy issue to reporting their findings. The results revealed marked differences in policy researchers’ attitudes and experiences. While policy scholars with a liberal outlook were found to be driven mainly by data to determine how policies work, researchers following a critical approach were more likely to base their studies on theory and to focus on meaning and questions regarding how and why. This paper also presents a framework to map out a pattern comprising key concepts and questions based on policy researchers’ approaches to policy analysis.

A Finite Grid Solution for Circular Plates on Elastic Foundations

Halim Kara,Polat Gülkan,Gultekin Aktas 대한토목학회 2015 KSCE JOURNAL OF CIVIL ENGINEERING Vol.19 No.4

The transmission of vertical or horizontal structural forces to the supporting soil is a challenge to analyze for structures on elastic foundation which represent a complex medium. The two-parameter elastic foundation model that provides a mechanical interaction between the individual spring elements shows a more realistic behavior of the soil reaction than does the single parameter Winkler model. Since the structural behavior of a beam resembles that of a strip in a plate, in this study, the exact stiffness and mass matrices of the beam element on two-parameter elastic foundation is extended to plates. The framework method that replaces a continuous surface by an idealized discrete system can represent a two-dimensional plate. In the light of this situation, circular plates are modeled as an assemblage of individual beam elements interconnected at their neighboring joints in radial and tangential direction. So, a useful tool called finite grid solution as a numerical method developed in this study lead to solve circular plates resting on two parameter elastic foundation problems. Examples for bending of ring, circular and annual plates on elastic foundation are solved to compare with known analytical solutions and other numerical solutions. The comparisons show that the literature and the computed results are compatible.

Development of Confidence Bound Visualization Tool for LTE-Based UAV Surveillance in Urban Areas

Halim Lee,Taewon Kang,Jiwon Seo 제어로봇시스템학회 2019 제어로봇시스템학회 국제학술대회 논문집 Vol.2019 No.10

We have developed a tool to visualize a situation of estimating the positions of unmanned aerial vehicles (UAVs) using long-term evolution (LTE) signals in an urban area. In our visualization tool, true positions of UAVs and evolved Node Bs (eNodeBs), estimated positions of UAVs, and the calculated horizontal and vertical protection levels (HPLs and VPLs) are displayed in a 3D city map. For a realistic simulation, the 3D city map is generated using real buildings and terrain data of Gangnam, Seoul, Korea. Users can directly specify the locations of UAVs and eNodeBs to simulate these cases. Error variances are added to the true range between UAVs and eNodeBs in the developed tool. Next, the position and the HPL and VPL of each UAV are calculated and displayed on the map. Using the developed visualization tool, we observed changes in the estimated positions and confidence bounds of UAVs by adjusting the number of eNodeBs transmitting LTE signals. Simulation results show that the size of confidence bounds decreases as the number of eNodeBs increases.

Pseudocapacitive Characteristics of Low-Carbon Silicon Oxycarbide for Lithium-Ion Capacitors

Halim, Martin,Liu, Guicheng,Ardhi, Ryanda Enggar Anugrah,Hudaya, Chairul,Wijaya, Ongky,Lee, Sang-Hyup,Kim, A-Young,Lee, Joong Kee American Chemical Society 2017 ACS APPLIED MATERIALS & INTERFACES Vol.9 No.24

<P>Lithium-ion capacitors (LICs) and lithium-ion batteries (LIBs) are important energy storage devices. As a material with good mechanical, thermal, and chemical properties, low-carbon silicon oxycarbide (LC-SiOC), a kind of silicone oil-derived SiOC, is of interest as an anode material, and we have examined the electrochemical behavior of LC-SiOC in LIB and LIC devices. We found that the lithium storage mechanism in LC-SiOC, prepared by pyrolysis of phenyl-rich silicon oil, depends on an oxygen-driven rather than a carbon-driven mechanism within our experimental scope. An investigation of the electrochemical performance of LC-SiOC in half- and full-cell LIBs revealed that LC-SiOC might not be suitable for full-cell LIBs because it has a lower capacity (238 mAh g(-1)) than that of graphite (290 mAh g(-1)) in a cutoff voltage range of 0-1 V versus Li/Li+, as well as a substantial irreversible capacity. Surprisingly, LC-SiOC acts as a pseudocapacitive material when it is tested in a half-cell configuration within a narrow cutoff voltage range of 0-1 V versus Li/Li+. Further investigation of a 'hybrid' supercapacitor, also known as an LIC, in which LC-SiOC is coupled with an activated carbon electrode, demonstrated that a power density of 156 000 W kg(-1) could be achieved while maintaining an energy density of 25 Wh kg(-1). In addition, the resulting capacitor had an excellent cycle life, holding similar to 90% of its energy density even after 75 000 cycles. Thus, LC-SiOC is a promising active material for LICs in applications such as heavy-duty electric vehicles.</P>
