The purpose of this investigation is to propose a planning method for the possibility of accepting a housing as a utilization plan of a long term unexecuted park site. Currently, the park has been neglected due to lack of financial resources of the local government. In 2009, It is possible to develop a certain area as a non-park facility under condition that the park is built and donated. In the several cities, various projects for development of parks are being carried out, so the standard for securing the publicness of the park is needed. So, I would like to solve the problems such as social conflict with existing residents due to privatization of the park site and formation of park without considering the conditions of the park, and to study how to effectively utilize the park. To do this, we examine the conditions such as location condition, proximity to public transportation, site size, topography, and contact conditions. And we will present realization methods such as land use, development density, appropriate development method considering landscape, efficient housing type, and type of community facility.

Subungual squamous cell earcinoma is an uncommon disease. Diagnosis of this condition is often delayed because of a resemblance to a variety of benign inflammatory conditions such as onychomycosis, chronic paronychia, eczema, and verruca vulgaris. The importance of an early skin biopsy for a chronic nonhealing subungual lesion is stressed. We present a case of subungual squamous cell carcinoma iri a 75-year-old man who had a 3-year history of intermittent swelling, erythema, and tenderness on the left 5th toe. The patient complained of a tender whitish verrucous 1.5cm-sized mass which had been present for a few months. A Histopathological study revealed invasive, well differentiated squamous cell carcinoma. (Kor J Dermatol 1997;35(4): 790-793)

The purpose of the study is to investigate the actual conditions of ready-to-wear Hanbok and is to establish the standard sizes for the women`s ready-to-wear Hanbok. Twelve ready-to-wear Hanbok shops were investigated for the actual survey. Body measurements were taken from May to June, 1990 from 329 female college students living in the Seoul and Buchon. The ages of the subjects were 18-26. Thirty seven measurements were taken from each subject and analized for the results. Data were analized by factor analysis, and regression analysis. The results were as follows 1. As a result of the actual survey, the situation of the quality label was not enough. The size classification was not unified, and was not trusted statistically, it cannot satisfied consumers. 2. Factor analysis identified the two dimensions of body measurements : one was relevant to the height measurements including stature and to the length measurements of limbs, and the other was relevant to the trunk girth measurements and the limbs girth measurements. 3. Because of plane construction of Hanbok, employed in this thesis was bi-dimensional sizing system using two controle dimensions including height factor(stature) and girth factor(bust girth). 4. The Multiple regression formula was developed for estimating secondary dimensions of Hanbok Construction, in which stature and bust girth were posited as independent variables. 5. As a results, about 88.63% of expected distribution were covered by 9 sizes, which were used as the basis for defining sizing system for Hanbok construction.

광학 시뮬레이션을 이용한 Patterned Sapphire Substrate에 따른 Flip Chip LED의 광 추출 효율 변화에 대한 연구

Recently many studies being carried out to increase the light efficiency of LED. The external quantum efficiency of LED, generally the light efficiency, is determined by the internal quantum efficiency and the light extraction efficiency. The internal quantum efficiency of LED was already reached to more than 90%, but the light extraction efficiency is still insufficient compared with the internal quantum efficiency because the total internal reflection is generated in the interface between the LED chip and air. Thus, we studied about flip chip LED with PSS and performed the optical simulation which find more optimized PSS for flip chip LED to increase the light extraction efficiency. Decreasing of the total internal reflection and effect of diffused reflection according to PSS improved the light extraction efficiency. To get more higher the efficiency, we simulated flip chip with PSS that the parameters are arrangement, edge spacing, radius, height and shape of PSS.

This study was carried out to examine foodborne pathogenic contamination from 1,080 samples of cooked hams and sausages at 10 Korean processing facilities in 2010. The samples were collected from the six primary and additional sterilization products in same lot. To detect Salmonella spp., Staphylococcus aureus, Listeria monocytogenes and Clostridium perfringens in those products (n=1,080), the domestic standard method for Processing and Ingredients Specification of Livestock Products was used. As a result, Salmonella spp. was not detected in all 636 ham and 444 sausage samples. However, L. monocytogenes was detected in four (0.6%) ham and eight (1.8%) sausage samples from five manufactures. S. aureus was also only detected in 4 (0.6%) ham samples from two manufacturers, and C. perfringens was detected in 3 (0.5%) ham samples from three manufacturers, the contamination levels of these pathogens were less than 100 CFU/g. In conclusion, the results of this study indicate that the additional sterilization step of processing manufacturers could not assist to control the foodborne pathogenic bacteria.

A flexible electrochromic device (ECD) is a promising technology that is expected to be applied in various fields such as smart windows. Polymer electrolyte is an important component that determines the bleaching-coloration performance and physical stability of flexible ECDs. In this study, a pore-filled polymer electrolyte membrane (PFPEM) with excellent dimensional stability was developed to effectively fabricate flexible ECDs and improve durability. Polyvinyl acetate, which has excellent adhesion, and polyethylene glycol, which can improve ionic conductivity, were filled in the pores of a porous substrate made of polyethylene, which is inexpensive and has excellent physical and chemical stability. The optimal lithium salt (LiTFSI) content of the prepared PFPEM was determined at about 27 wt%, and it was confirmed to possess excellent dimensional stability, adhesive strength, and ion conductivity close to that of conventional polymer electrolytes. Although the visible light transmittance was lowered by the use of the porous substrate, it was expected to act as an advantage in the colored state.

박현정,안상건,김정상,Park, Hyun-Jeong,Ahn, Sang-Gun,Kim, Jeong-Sang 한국식품영양과학회 2007 한국식품영양과학회지 Vol.36 No.4

흰쥐 우측요부에 RK3E-ras cell주입으로 7일 이내에 종양이 발달하는 것을 관찰하고, 단삼 추출물을 제조하여 항종양 효과를 관찰하고자 1주 후부터 2주 동안 육종 부위에 투여 후 종양의 크기와 무게를 측정하고 조직학적인 관찰을 통하여 암세포의 발달과 암전이 유무를 살펴보았다. 암종의 크기는 대조군에 비하여 단삼 추출물을 투여한 실험군에서 현저히 감소(p<0.01)하였으며, 암종의 중량 또한 실험군에서 현저히 감소(p<0.01)하였다. 조직학적 관찰 결과 종양을 둘러싸고 있는 섬유막은 대조군에 비하여 실험군에서 발달 해 있었으며, 암세포의 밀도는 실험군에 비하여 대조군에서 높았다. 간조직을 관찰한 결과 대조군의 간문맥 주변에서 전이된 것으로 보이는 암세포들이 다수 관찰되었다. 이와 같은 결과를 토대로 단삼 추출물이 항종양효과가 있다고 사료된다. The present study was carried out to investigate the antitumor activity of Salvia miltiorrhiza (SM) herbal extract in rat tumor model. We used a new tumor animal model for the invasion and metastasis of cancer using genetically k-ras-induced rat kidney cells (RK3E-ras). We observed tumor as early as 7 days after the injection of RK3E-ras cells in subcutaneous of Sprague-Dawley rats. All of the rats developed tumor mass at the inoculated site. After 7 days, the experimental groups were divided into two: saline control and injected with SM (200 mg/kg) groups. We investigated tumor's weight, size and hepatic metastasis of each group. Injection of SM herbal extract every other day for 14 days significantly inhibited tumor growth. Histologically, the tumors were undifferentiated carcinoma showing multifactorial necrosis and hemorrhage; also, the tumor invaded into hepatoportal region. Treatment with SM herbal extract caused significant inhibition of tumor cell proliferation. Our data showed that SM herbal extract is effective in controlling the tendency of tumor cell proliferation and metastasis by injection of RK3E-ras cells. These findings provided the potential value of SM as a novel antitumor agent candidate.
