According to the relation of the attribution of residents, we analyzed the spatial characteristics of newly-built Hanok in Bukchon focused on a spatial area-ratio, the number of rooms, L/D/K configuration. The results are as follows: 1) Have increased the number of residents, the family members are also increased. In this study, the major formed case is 3 residents and two-generation family. 2) In the most cases, R area-ratio is the highest, next to L/D/K integrated area-ratio. While the examples that the L/D/K integrated area-ratio is lower than R area-ratio, or is also higher than R area-ratio are appeared. These examples can present that it has a tendency to secure the necessary room depending on the attribution of residents. 3) L/D/K is classified into four types of connection. And the characteristics depending on the number of rooms are as follows. L+DK is the most common type, next to LDK>LD+K>L+D+K. And L+DK is widely distributed in each sized area. And particularly, it is appeared mostly in 3R.

Introduction: Quality of life (QoL) issues are of importance in relatives of women with breast cancer (BC)as caregivers in neglecting their own needs due to care of a patient and also as women regarding the potential risk of themselves developing BC. The objectives in the present study were to compare the QoL of female relatives of women in treatment for breast cancer. To date, no study had examined multi-dimensional QoL in accompanying people as compared them into two groups of female relatives whose first degree and second degree. Methods: QoL of female relatives was assessed using the Quality of Life-Family Version (QOL-FV) scale. Relationships between socio-demographic characteristics and QoL scores were analyzed using the Mann-Whitney U, Kruskal Wallis and Crosstabs tests. Results: The mean age of the female relatives was 37.6 years, and nearly 48% had a university education. It was found that first degree relatives had worse QoL in all domains except physical wellbeing than second degree relatives. Conclusion: This study showed that being female relatives of BC, especially first-degree, affect QoL negatively. Health care providers are of an important role in the stage of information related to genetic influence of BC.

연구 이용 수정 재배포를 허용하는 오프소스 소프트웨어(OSS)는 경쟁이 아닌 협력과 공유를 통해 발전해 나가는 도서관 정신과 유사하다. OSS는 사서들의 창의적 아이디어와 표준 업무프로세스를 기반으로 저비용 기술혁신을 실현할 수 있는 대안으로 평가되고 있으나, 지속적 발전을 위해서는 경험과 지식을 공유하는 성숙한 커뮤니티 정신이 요구된다. 본 연구에서는 커뮤니티 중심의 OSS ILS 사례인 KOHA와 Next_L을 심층 분석하고 이를 기반으로 국내 OSS ILS의 실현 방안을 제안하였다. 우리나라의 경우 관종별 도서관 컨소시엄을 중심으로 중소규모 도서관을 위한 OSS ILS 개발을 추진해 나가는 것이 바람직해 보인다. 그러나 아직 생소한 OSS ILS 필요성에 대한 현장의 공감대 형성, 커뮤니티 활성화를 위한 기운의 성숙이 전제되어야 할 것이다.

The digital current differential relaying scheme is widely used for primary protection of 765(kV) power transformer. The current differential relay pickup the internal fault at the threshold which is set at 30% of rating current. Margin of 30% include current transformer error 5%, relay error 5%, on load tap changer error 7% and margin factor 140% obtained from the field experience. In this paper transformer protection relay and relay setting rule of high voltage power system are discussed. And we verify the correctness of relay setting rule with current differential relay using Matlab simulation.

This paper presents the methods to solve the problem about Power System Protection Program(PROSET). PROSET is a overall program system to protect power system and correct it. In the context of the PROSET, it is so difficult to edit database data when topology is changed. When the renewal of data is performed, all changed values are disappeared. Therefore, it will not be expected to know the present situation by using the information of the databases data. So it is necessary to solve this problem. Solution is copy of the user. Database of GRL,GRZ,KYP2D1,KYD2X1,L90 Relay module were developed. We made a database management system for PROSET, therefore I will show this management system briefly.

Objective: 'Cultured meat' has been suggested as means of solving the problems associated with overpopulation and gas emissions. Satellite cells are a major component in the production of cultured meat; however, these cells cannot be maintained in vitro over long periods. Fibronectin is a glycoprotein that affects biological processes such as cell adhesion, differentiation, and migration. Unfortunately, the characteristics of porcine satellite cells grown in a long-term culture when exposed to fibronectin-coated dishes are unknown. The objective of this study was to investigate the appropriate concentration of fibronectin coated dishes for proliferation and maintenance of porcine satellite cells at long-term culture. Methods: In this study, we isolated the satellite cells and fibroblast cells with pre-plating method. We next analyzed the cell doubling time, cell cycle, and rate of expressed paired box 7 (Pax7) and myogenic differentiation 1 (MyoD1) in porcine satellite cells cultured with 20 ㎍/mL of fibronectin-, gelatin-, and non-coated dishes at early and late passage. We then analyzed the proliferation of porcine satellite cells with various concentrations of mixed gelatin/fibronectin. We next determined the optimal concentration of fibronectin that would encourage proliferation and maintenance of porcine satellite cells in a long-term culture. Results: Doubling time was lowest when 20 ㎍/mL of fibronectin was used (as tested during an early and late passage). Levels of expressed Pax7 and MyoD1, assessed using immunocytochemistry, were highest in cells grown using fibronectin-coated dishes. The proliferation of gelatin/fibronectin mixed coatings had no significant effect on porcine satellite cells. The concentration of 5 ㎍/mL fibronectin coated dishes showed the lowest doubling time and maintained expression of Pax7. Conclusion: Fibronectin with 5㎍/mL effectively maintains porcine satellite cells, a discovery that will be of interest to those developing the next generation of artificial meats.

In this paper, (E, L)-preproximity and uniformity spaces in matriod theory as a generalized to a classical proximity and Uniformity spaces introduced by Csaszar [1] is introduced. Recently, Shi [17]-[18] introduced a new approach to the fuzzification of matroids.Here introduce (E, L)-preproximity and uniformity spaces, Uniformity and strong uniformity on (E, L)-fuzzifying matroid space, Not only study the properties of this new notions, but it has been generated (E, L)-fuzzifying matroid Space from (E, L)-preproximity and uniformity spaces. Next to introduced (E, L)-preproximity continuous in (E, L)-fuzzifying matroid space and used it in more properties. Finally we solve combinatorial optimizations problem via (E, L)-fuzzifying matroid space.

We report a case of cauda equine syndrome following caudal anesthesia possibly caused by metastatic spine tumor. Male, 80-year-old, who had prostatic carcinoma with $L_3$ and $L_4$ spine metastasis was scheduled for bilateral orchiectomy. Twenty two-gauge needle was introduced at sacral hiatus and 15 ml of 2% lidocaine administered. The next morning, patient complained of perineal numbness and urination difficulty. During the next several day patient had episodes of fecal incontinence and motor weakness on both lower extremities. This case reminded us that neuroaxial blocks such as spinal, epidural and caudal anesthesia, should be used with extreme care in patients having neoplasm with high incidence of spine metastasis.
