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.

Selective Harmonic Elimination for a Single-Phase 13-level TCHB Based Cascaded Multilevel Inverter Using FPGA

Halim, Wahidah Abd.,Rahim, Nasrudin Abd.,Azri, Maaspaliza The Korean Institute of Power Electronics 2014 JOURNAL OF POWER ELECTRONICS Vol.14 No.3

This paper presents an implementation of selective harmonic elimination (SHE) modulation for a single-phase 13-level transistor-clamped H-bridge (TCHB) based cascaded multilevel inverter. To determine the optimum switching angle of the SHE equations, the Newton-Raphson method is used in solving the transcendental equation describing the fundamental and harmonic components. The proposed SHE scheme used the relationship between the angles and a sinusoidal reference waveform based on voltage-angle equal criteria. The proposed SHE scheme is evaluated through simulation and experimental results. The digital modulator based-SHE scheme using a field-programmable gate array (FPGA) is described and has been implemented on an Altera DE2 board. The proposed SHE is efficient in eliminating the $3^{rd}$, $5^{th}$, $7^{th}$, $9^{th}$ and $11^{th}$ order harmonics, which validates the analytical results. From the results, it can be seen that the adopted 13-level inverter produces a higher quality with a better harmonic profile and sinusoidal shape of the stepped output waveform.

<▼1><P>Silicon oxycarbide (SiOC) is gaining increasing attention as a promising anode material for lithium ion batteries due to its higher reversible capacity compared to incumbent graphite.</P></▼1><▼2><P>Silicon oxycarbide (SiOC) is gaining increasing attention as a promising anode material for lithium ion batteries due to its higher reversible capacity compared to incumbent graphite. The kinetic processes at a SiOC anode result in rapid capacity fading even at a relatively low current density, thereby hindering its commercialization. Herein, a distinctive, phenyl-rich silicone oil is used as a precursor for producing SiOC anode materials <I>via</I> simple pyrolysis. We find that only silicone oil with phenyl-rich rings can be converted into SiOC materials. The phenyl group was crucial for carbon incorporation to allow Si–O–C bonding and the formation of a free-carbon phase. The resulting SiOC anode exhibited stable cyclability up to 250 cycles, with a discharge capacity of 800 mA h g<SUP>−1</SUP> at a current density of 200 mA g<SUP>−1</SUP>. The remarkable cycle performance of SiOC was correlated with its low dimensional expansion (7%) during lithiation, which maintains its structure over cycling. Rate capability tests showed a highly stable performance with a maximum discharge capacity of 852 mA h g<SUP>−1</SUP> at a current density of 100 mA g<SUP>−1</SUP>. When the discharge current density was increased 64-fold, the reversible capacity of the SiOC anode was 90% of its maximum capacity, 772 mA h g<SUP>−1</SUP>. The excellent electrochemical performance of SiOC could be attributed to the rapid mobility of Li<SUP>+</SUP> within the SiOC matrix, as indicated by a Li<SUP>+</SUP> diffusion coefficient of 5.1 × 10<SUP>−6</SUP> cm<SUP>2</SUP> s<SUP>−1</SUP>.</P></▼2>

Neural Network-Based Ranging with LTE Channel Impulse Response for Localization in Indoor Environments

Halim Lee,Ali A. Abdallah,Jongmin Park,Jiwon Seo,Zaher M. Kassas 제어로봇시스템학회 2020 제어로봇시스템학회 국제학술대회 논문집 Vol.2020 No.10

A neural network (NN)-based approach for indoor localization via cellular long-term evolution (LTE) signals is proposed. The approach estimates, from the channel impulse response (CIR), the range between an LTE eNodeB and a receiver. A software-defined radio (SDR) extracts the CIR, which is fed to a long short-term memory model (LSTM) recurrent neural network (RNN) to estimate the range. Experimental results are presented comparing the proposed approach against a baseline RNN without LSTM. The results show a receiver navigating for 100 m in an indoor environment, while receiving signals from one LTE eNodeB. The ranging root-mean squared error (RMSE) and ranging maximum error along the receiver’s trajectory were reduced from 13.11 m and 55.68 m, respectively, in the baseline RNN to 9.02 m and 27.40 m, respectively, with the proposed RNN-LSTM.
