U. S. NRC Regulation Guide 1.52 regulating ESF ACS in nuclear power plants has been revised to revision 3. To apply reduction of operability test time, allowance of alternative challenge agents for in-place leak test of HEPA filters, and upgrade of Methyl Iodide penetration acceptance criterion in activated carbon performance test suggested in Reg. Guide 1.52(Rev.3) on Yonggwang units 5 and 6 ESF ACSes, technical feasibility study was carried out with on-site experiments as well as experiments with a lab-scale model. It was confirmed that the moisture in the system returned to the level before the test in 1 or 4 days even though the moisture was removed during the operability test lasting more than 10 hours. Therefore, it is appropriate to perform monthly operability test in 15 minutes just long enough to check the operability of equipment. To change challenge material for in-place HEPA filter leak test, size of aerosol, production rate, and leak detection capability were compared for DOP and PAO. It was concluded that PAO can be substituted for DOP in nuclear power plants. The upgrade of Methyl Iodide penetration acceptance criterion from 0.175 % to 0.5 % in active carbon filter bed deeper than 4 inches was to conform to the change of activated carbon performance test method to ASTM D3803(1989). It was confirmed that Methyl Iodide penetration acceptance criterion of 0.5 % under $30^{\circ}C$, relative humidity 95 % condition was conservatively good enough for testing performance of active carbon insitu. The licence change of Yonggwang units 5 and 6 has been completed based on this study.

A nuclear plant ESF ACS simulator was designed, built, and verified to perform experiment related to ESF ACS of nuclear power plants. The dimension of 3D CAD model was based on drawings of the main control room(MCR) of Yonggwang units 5 and 6. The CFD analysis was performed based on the measurement of the actual flow rate of ESF ACS. The air flowing in ACS was assumed to have $30^{\circ}C$ and uniform flow. The flow rate across the HEPA filter was estimated to be 1.83 m/s based on the MCR ACS flow rate of 12,986 CFM and HEPA filter area of 9 filters having effective area of $610{\times}610mm^2$ each. When MCR ACS was modeled, air flow blocking filter frames were considered for better simulation of the real ACS. In CFD analysis, the air flow rate in the lower part of the active carbon adsorber was simulated separately at higher than 7 m/s to reflect the measured value of 8 m/s. Through the CFD analyses of the ACSes of fuel building emergency ventilation system, emergency core cooling system equipment room ventilation cleanup system, it was confirmed that all three EFS ACSes can be simulated by controlling the flow rate of the simulator. After the CFD analysis, the simulator was built in nuclear grade and its reliability was verified through air flow distribution tests before it was used in main tests. The verification result showed that distribution of the internal flow was uniform except near the filter frames when medium filter was installed. The simulator was used in the tests to confirm the revised contents in Reg. Guide 1.52 (Rev. 3).

Dermatophytes have been demonstrated infrequently in viable tissues such as dermis, subcutis, lymph nodes, bones and other organs. Mycetoma-like lesions caused by dermatophytes, known as pseudomycetoma, have been very rarely reported. A 56-year-old woman presented with several protruding bean to chestnut-sized subcutaneous nodules on the occipital region of the scalp. She had a long term history of epidermolysis bullosa acquisita and intermittent administration of systemic corticosteroids for 5 years. Histopathology of the subcutaneous nodules showed a well encapsulated granuloma containing characteristic lobulated granules consisted of mycelial aggregates. Trichophyton mentagrophytes grew out on the cultures of Sabouraud's media with excised tissues. Surgical excision and itraconazole 200mg per day for 10 weeks was tried and skin lesions are improved with focal recurrence. (Kor J Dermatol 1996;34(3): 480-484)

Cirsoid aneurysm of the calp is a congenital arteriovenous malformation which is the result of abnormal connections betwe:.n the external carotid artery and scalp veins with a subsequent dilatation of vascular channels nd formation of aneurysm. We report a case of cirsoid aneurysm of the scalp on the left parieto-occipital area of 14-year-old female who had had 8 x 5 x 0.8 cm sized pulsating soft mass for 2 years. 4 vessel angiog raphy revealed a arteriovenous malformation that emerge mainly from a superficial temporal artery and occipital artery of the left external carotid artery and partially from the right superficial temporal artery and drined into the left scalp vein. The mass was removed by excision with ligation of the feeding arter es and followed up for 2 years without recurrence. (Kor J Dermatol 1995;33(5): 940-944)

Prurigo pigmentosa is a chror ic pruritic inflammatory dermatosis characterized by erythematous papules in a reticulated pattern that resolve leaving a reticulated, mottled hyperpigmentation and rapidly response to dapsone therapy. Most cases that have been reported are from Japan. We report two cases of prurigo pigmentosa in a 21 year-old female and a 23-year-old female. Histopathologic findings of erythematous papules showed exocytosis, spongiosis, liquefaction degeneration of basal cell layer and perivascular lymphohistiocytic infiltration on the upper dermis. We treated them with dapsone, 100mg daily, which resulted in a remarkable regression of the ery thematous papules and improvenien of pruritus. (Kor J Dermatol 1995;33(5): 945-949)

Infantile hemangiomas are benign vascular tumors that commonly occur in infants. The management of hemangiomas ranges from simple observation and assurance to surgical resection. The commonly used treatment modalities include topical, intralesional and systemic steroids, pulsed dye laser and surgical excision. There are several reports of infantile hemangiomas treated with direct percutaneous injections of sclerosing agents such as ethanol, polidocanol or ethanolamine oleate. We report here on a case of infantile hemangioma that was treated with ethanolamine oleate by dermal injection. We think this is the first report of a dermal injection of ethanolamine oleate, and not intraluminal injection, for treating infantile hemangioma. (Korean J Dermatol 2010;48(7):627∼630)

이 연구는 품새도복의 제품속성과 브랜드이미지, 품질만족의 관계를 규명하여 태권도복 산업의 마케팅 전략 수립을 위한 기초자료를 제공하는데 목적이 있다. 연구 대상으로는 2016년 대한태권도협회 선수등록을 한 품새선수를 중심으로 편의표본추출법을 통해 배포 및 회수하여 총358부의 설문지를 분석하였다. 자료처리 방법은 PASW 23.0와 AMOS 23.0을 이용하여 빈도분석, 탐색적 요인분석, 신뢰도분석, 상관관계분석, SEM을 실시하여 다음과 같은 결론을 얻었다. 첫째, 품새도복 제품속성은 브랜드이미지에 유의한 영향을 미치는 것으로 나타났다. 둘째, 품새도복 제품속성은 품질만족에 유의한 영향을 미치는 것으로 나타났다. 셋째, 품새도복 브랜드이미지는 품질만족에 유의한 영향을 미치는 것으로 나타났다. 이러한 결과를 통해 품새선수는 자신의 개성과 무술적 가치를 살릴 수 있고 경기적인 측면을 극대화 할 수 있는 기능성 품새전용경기복을 추구하고 있음을 알 수 있다. 따라서 품질이 우수한 도복개발을 통해 품새 경기적 측면을 접근한 편의성과 만족도를 증대시키는 등 태권도복 브랜드 강화를 위한 주요 수단이 되어야 할 것이다. The purpose of this study is to determine the relationship among product attributes, brand image and quality satisfaction of a Taekwondo Poomsae uniform and to provide basic data for the establishment of a marketing strategy of the Taekwondo uniform manufacturing industry. The athletes who participated in the Korea Taekwondo Poomsae Championships that held in 2016 were selected as participant a total of 358 questionnaires that collected by convenience sampling method were analyzed using SPSS ver. 23.0 and AMOS ver. 23.0. Firstly, the product attributes of a Taekwondo Poomsae uniform had a significant effect on brand image. Secondly, the brand image of a Taekwondo Poomsae uniform had a significant effect on quality satisfaction. Thirdly, the product attributes of a Taekwondo Poomsae uniform had a significant effect on quality satisfaction. Based on the findings, researcher was able to know that Poomsae athletes are preferring functional Poomsae uniform that could increase their performance and martial arts value, and show their individuality. Therefore, taekwondo uniform brands must be increased by developing the high quality uniform that increase both convenience and satisfactions of athletes.
