엔진룸에 대한 CFD 해석을 처음 시도 되었지만, 그 기초 연구로서 충분한 결과를 얻었으며, 특히 본넷트 전면 개공 면적의 경우 초기 대비 83% 수준으로 감소시킬 수 있었다. 또한 해석의 유효성 검증을 위해 시험 값을 비교하여 본 결과 5% 내외 정확성을 확인할 수 있었다. 그리고 무엇보다 본 연구를 통해 설계에 대한 시제품 검증을 제품을 만들지 않고 사전에 최적화 할 수 있는 접근성을 확보했다는 것이 가장 큰 성과라고 할 수 있다.

This study presented the specific analysis of meteorological factors to investigate local climate change of Busan and deduced the characteristics of meteorological elements such as monthly temperature, relative humidity, wind, and precipitation by the influence of urbanization and geographical features. This study used data obtained from Busan Regional Meteorological Office and Automatic Weather System (AWS) for the recent 30 years (1971 to 2000). In analyzing meteorological elements, air temperature, precipitation and hours sunshine show a slightly increasing trend, and wind speed, relative humidity, cloud amount, and radiation show a decreasing trend. A special point is that increasing radio of maximum temperature is higher than that of minimum temperature, then the daily range of temperature is gradually increasing. In addition, the characteristics of local climate vary as each area in Busan. At Seomyeon and Dongnae area which are located at the center of Busan, heat island phenomena occurred over all seasons, especially its intensity is the strongest in August. The annual precipitation is highest at Youngdo, Daecheongdong, Ilgwang which are located at the seaside. Wind velocity is relatively strong at the southern seaside.

This study is purposed to propose indices in order to achieve goals such as preventing one-sided movement of balance, preventing injuries to joints of legs, improving muscular strength of legs, and maximizing sporting achievement with the use of a bar pad for athletes as well as nonathletes. In terms of methodology, this study has compared foot pressure distribution and foot pressure ratio during full-squat and half-squat exercise. As a result of analysis on impact of full-squat and half-squat exercise on foot pressure distribution and foot pressure ratio with a bar pad and without a bar pad, conclusions have been obtained as shown below. Foot pressure distribution between left and right feet of subjects during full-squat exercise with and without a bar pad showing significant decline of the distintion of both feet pressure when using a bar pad. Foot pressure distribution between left and right feet of subjects during half-squat exercise with and without a bar pad showing significant drop of the distintion of both feet pressure when using a bar pad. Foot pressure ratio of front feet of subjects during full-squat exercise without and with a bar pad showing no significant difference. Foot pressure ratio of front feet of subjects during half-squat exercise without and with a bar pad showing no significant difference.

In this paper, the effect of silane-treated silicas and epoxidized soybean oil (ESBO) addition on adhesion properties of silicas-filled epoxy adhesives was examined. The silicas were treated by γ-methacryloxy propyltrimethoxy silane (MPS), γ-glycidoxy propyl trimethoxy silane (GPS), and γ-mercapto propyl trimethoxy silane (MCPS). Surface and structural properties of the adhesives were determined by using scanning electron microscope (SEM) and Fourier transform infrared spectroscopy(FT-IR). The t-peel strength of the adhesives was estimated using the universal testing machine (UTM). And, the equilibrium spreading pressure, surface free energy, and specific surface area were investigated by BET methods with N2/77 K adsorption. As a result, the peel strength of the adhesives was increased in the presence of silane-treated silicas in the adhesives compared to that of untreated silicas. This result indicated that the silane coupling agent played an important role in improving the dispersion of silicas in epoxy adhesives. And, the adhesives treated by MCPS were superior to the others in adhesion.

In this paper, the thermal behaviors of expanded graphite(EG)/erythritol composites with different contents of EG were studied. The surface and structure properties of the composites were determined by using scanning electron microscope(SEM), transmission electron microscope (TEM), and X-ray diffraction (XRD), respectively. The thermal properties were investigated by differential scanning calorimetry (DSC) and thermal conductivity (TC). As experimental results, the thermal conductivityof the composites increased with increasing the EG content. However, the latent heat was somewhat decreased in the presence of EG. We could concluded that EG was highly promising materials for improving the heat transfer enhancement and energy storage capacity of phase change materials (PCMs).

Mycoplasma pneumoniae associated stroke in a 3-year-old girl

Infectious diseases precede a significant proportion of acute ischemic strokes in children. Here, we report a case of acute ischemic stroke in a 3-year-old girl with a Mycoplasma pneumonia-associated respiratory tract infection. She developed an acquired prothrombotic state of protein S deficiency and had increased fibrinogen and fibrinogen degradation product levels and increased titer of antinuclear antibodies. However, these conditions were completely alleviated at the 1-month follow-up examination. Infection with M. pneumoniae may cause a transient prothrombotic state that can potentially cause a thrombus.

전자책의 공중송신 사용료에 관한 연구

출판콘텐츠의 제작과 이용이 변화하고 있는 현 상황에서 저작권 사용료는 중요하다. 최근 <저작권법>의 전면개정이 발의되기는 했지만, 전자책과 같은 새로운 형태는 저작권법에 적용되기 어렵고, 공중송신과 같은 이용 형태에 대한 사용료 기준도 마련되지 않은 실정이다. 이에 본 연구는 출판콘텐츠 기업을 대상으로 어문저작물의 공중송신 사용료 지급 실태와 이에 대한 인식을 알아보았다. 그 결과, 어문저작물 유형 중 산문의 이용이 많고, 저작권과 저작물 사용료를 저작자와의 개별 계약을 통해 진행하며 신탁관리단체보다는 대리중개업체를 통하고 있었다. 출판콘텐츠기업은 신탁관리단체의 저작권 이용료 상승 폭이 높다고 인식하고 있고, 신탁관리단체의 저작물 사용료와 다르게 자율적으로 부과되고 있는 상황에 대해 대리중개업체도 신탁관리단체와 동일한 기준을 적용하도록 해야 한다고 인식하고 있었다. 새로운 형태의 전자책이 발달하고 있는 현 상황에서 종이책 기반의 현 상황에서 벗어나 다양한 방식에 대비할 수 있도록 공중송신 사용료 규정이 구체화 될 필요가 있다. The production and use of published content are changing, copyright royalties for production and use are important. Although a full revision of the <Copyright Act> has been proposed recently, new forms such as e-books, audiobooks are difficult to apply to the current Copyright Act. Especially, there is no standard for copyright royalties for new usage such as public transmission. Therefore, this study tried to investigate the positions of major actors on the public transmission royalties that have not yet been prepared, focusing on literary works. As a result, among the types of literary works, the use of prose was common, and copyrights and royalties were carried out through an individual contract with the author, and instead of a trust management organization. Publishing content companies recognize that trust management organizations have a high rate of increase in copyright royalties, and in the situation where they are voluntarily charged differently from trust management organizations’ royalties for copyrighted works, they recognize that agencies should apply the same standards as trust management organizations. In the current situation where a new type of e-book is being developed, the public transmission fee regulation should be concreted so that it can be prepared for various methods by breaking away from the current situation based on paper books.

To study repellent of Drosophila melanogaster, we extracted plant materials from wild sesame leaf, cinnamon, fig leaf, ginko leaf, quince with 100% ethanol or water as an extract solvent and described an insecticidal effect on the plant extract respectively. In the result, the 100% ethanol extract had higher insecticidal effect than the water extract. The ethanol extract of wild sesame leaf showed 58% extinction effect on Drosophila and the extracts of cinnamon and fig leaves had the effect of repellent. Each ethanil extract and the extract of cinnamon water were mixed with the ethanol extract of wild sesame leaf and a secondary test on the repellent effect has been conducted. In case of cinnamon extract mixed with wild sesame leaf, it showed no larva development and low Drosophila influx and also confirmed the same effect in the ethanol extract of fig leaf. The ethanol extract of wild sesame leaf has aromatic compound and high level of flavonoid concentration that affect like lure materials and accelerate a repellent effect of Drosophila. The cinnamon extract has high concentration of phenol compound that reasons material on repellent effect. However, the effect of fig leaf can not describe because it is low concentration of phenol compound and flavonoid compared with wild sesame leaf and cinnamon. Therefore, in case of mixed plant extracts with the ethanol extract of wild sesame leaves it can make repellent product to induce larva inhibition and insecticidal effect.
