Although 20 years have passed since the implementation of Koreas first Free Trade Agreement (FTA), Origin vertification remains a significant challenge for businesses. The violation rate of origin import verification still exceeds 50%. In response, this study reviews the processes involved in the origin verification tasks performed by the Korea Customs Service and analyzes the reasons behind origin violations. The analysis reveals that origin verification violations are most frequently observed in the Korea-China FTA, with criteria for origin determination and direct transportation requirements resulting in aditional duty and taxes of approximately KRW 110 million and KRW 470 million per company, respectively. In contrast to previous studies that primarily focused on fragmented case analyses related to origin verification, this research presents a comprehensive examination and cases of verification tasks, representing a novel approach in the study of FTA origin verification.

본 연구는 3차병원에서 퇴원하는 환자의 상처관리에 대한 지식과 염려사항을 파악하기 위해 112명의 피부상 처를 지니고 퇴원을 앞둔 112명 환자에게 구조화된 설문지로 면담을 통해 조사하였다. 상처의 유형은 외과적 절개 (52.7%), 삽관상처(26.8%), 욕창(9.8%), 당뇨발과 동맥궤양(5.4%) 등이었다. 상처관리에 관한 지식은 52.0%의 정답률을 보였고, 상처관리에 대한 염려(범위1-7)는 2.79였고, 상처관리에 대한 지식과 염려는 상관관계가 유의하지 않았다. 퇴 원후 상처관리에 관한 염려에 영향을 미치는 요인으로 유의한 변수는 상처관리에 대한 두려움, 상처통증, 입원기간, 및 주관적 건강인식으로 나타났다. 상처를 지니고 퇴원하는 환자들의 상처관리에 대한 지식은 부정확한 것이 많으며 다양한 염려사항들을 가지고 있으므로 퇴원계획시 이에 대한 구체적인 교육이 필요할 것이다. This study was done to examine patients' wound care knowledge and concerns prior to discharge from a tertiary hospital. The participants in this descriptive survey were 112 patients having wounds. During interview, a structured self-administered questionnaire was filled out. The participants were 71 males and 41 females. Wound types were surgical incision (52.7%), percutaneous wound (26.8%), pressure ulcer (9.8%) and diabetic foot and arterial ulcers (5.4%). Their wound care knowledge was 52.0% of correct answer and the mean of concerns (range 1-7) was 2.79. There was no significant correlation between their knowledge and concerns of wound care. The factors influence on wound care concerns were fear of wound care, wound pain, length of hospital stays, and perceived health condition. This findings showed that discharge patients with a wound had some incorrect knowledge and various concerns about wound care. They may help to direct patient teaching in discharge plan.

SFT, which has a high glass fiber content, is one of the effective methods to replace metal and secure weight reduction and price competitiveness. This study evaluated the effect of glass fiber shape on mechanical properties in injection molding by fabricating SFT with a glass fiber content of 60%. Three types of SFTs were manufactured by adding round glass fibers of Φ7 μm and Φ10 μm and flat glass fibers of 27 × 10 μm. DOE (Design of Experiment) conducts to confirm the change in tensile strength due to changes in significant injection conditions. As a result of the experiment, Φ7 μm SFT and flat SFT have similar tensile strength and Φ10 μm SFT showed the lowest tensile strength value. As for the standard deviation of strength value, the Φ7 μm SFT had the largest standard deviation, and the Φ10 μm SFT showed the slightest change in the injection conditions. In flat SFT, it confirms that the tensile strength increased as the molding temperature increased. The fracture surface observes using SEM. It founds that the tensile strength lowers due to the small glass fiber density and many pullouts at the fracture surface of Φ10 μm with weak strength.

About 170 years has been passed since the concept of photovoltaic has been suggested by French physicist Alexandre-Edmond Becquerel. Now the highest efficiency of solar cell has reached up to 44% by III-V multi-junction solar cells with concentrator. Those multi-junction solar cells are suitable as energy source for spaceships. On the other hand, the cell efficiency of solar cell for electric power generation as energy source for Earth has is going to be saturated although commercial solar cell efficiency is around 20%. In the part 1 of this article, the history of III-V multi-junction solar cells which have been adapted for spaceships is explained and in the part 2, new approach for the improvement of cell efficiency is suggested as the energy source for Earth.
파장대역폭이 넓은 고휘도 발광소자를 위한 Chirped 양자점 구조의 광/전기 특성 분석
한일기,Han, Il-Ki 한국진공학회 2009 Applied Science and Convergence Technology Vol.18 No.5
크기가 다른 양자점 (chirped 양자점) 구조에 대하여 전기발광 (Electroluminescence, EL) 특성과 광발광 (Photoluminescence, PL) 특성을 측정하고 비교 분석하였다. PL 특성에서는 양자점의 기저준위에 의한 피이크가 우세하게 나타난 반면, EL 특성에서는 여기준위에 의한 특성이 우세하게 나타났다. 이와 같은 특성비교로부터 기저준위도 EL 특성에 영향을 미칠 수 있도록 chirped 양자점 구조를 설계하면 파장대역폭이 더욱 넓은 고휘도 발광소자 개발이 가능할 것임을 제안하였다. We analyzed photoluminescence (PL) and electroluminescence characteristics of various chirped quantum dot structures. Peaks in EL curves were contributed by excited states of quantum dots (QD), while those in PL curves by grounded states. Based on these characteristics, we suggested that superluminescent diodes with wide spectral bandwidth may be developed if chirped QD structures are designed to make a contribution by ground states to EL characteristics.

Eteching characteristics of the Indium Tin Oxide (ITO), which is transparent conductor, was investigated with CH4/H2 and Ar as etching gases for the Reactive Ion Etching (RIE). With CH4/H2 for the etching gas, the highly selective etching characteristics for the ITO on GaAs was obtained. It was examined that the dominant etching parameter for the selective etchning of ITO on GaAs structure was the chamber pressure. But, the etching selectivity for ITO on InP was poor eventhough we tried systematic etching. RIE etching conditins using CH4/H2 gas was limited due to the formation of polymer on the substrates. In the case of Ar gas for the reactive gas, the selectivity of ITO on BaTiO3 was above 10. The etch rete of ITO was more sensitive to the etching parameters than that of BaTiO3, which was almost constant with different etching parameters.

Linewidth enhancement factor ($\alpha{-factor}$) 값이 2와 4인 두 종류의 1.55${\mu}m$ 다층양자우물(Multi-Quantum Well; MQW) 대면적 레이저 다이오드를 제작하였다. 제작된 레이저 다이오드의 far-field 측정 결과 $\alpha{-factor}$ 값이 4일 때 보다 2인 구조에서 반폭치(Full Width at Half Maximum; FWHM)와 필라멘테이션(filamentation)이 감소되었다. 주입전류의 증가에 따라 두 종류 모두 far-field의 FWHM의 증가 현상이 나타났고 이는 filament spacing이 감소하였기 때문으로 설명된다. 1.55 ${\mu}m$multi-quantum well (MQW) broad area laser diodes with different linewidth enhancement factors ($\alpha{-factor}$) of 2 and 4 were fabricated. The far-fields of the laser diodes were measured. It was observed that the full width at half maximum (FWHM) of the far-fields and the filamentations were reduced in the laser diodes for which the value of the $\alpha{-factor}$ was small. As injection current increased, the FWHM of the far-field also increased regardless of the a-factor. This phenomenon was explained by reduction of filament spacing as injection current increased.
