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.

The idea behind Open Source Software(OSS) that permits users to study, change, and improve, is similar to the spirit of the library that has been developed through cooperations and resource sharing rather than competition. OSS is regarded as an alternative, low-cost technical innovation based on librarian's creative idea and standardized business process. Enthusiasm of the community is fundamental to successful installations and sustainable development. This study analyzed two community-based OSS ILS, namely KOHA and Next_L and suggested a future direction for domestic libraries. In the case of Korea, it is desirable for a library consortium to develop an OSS ILS for small- and medium-sized libraries. Most importantly, strong consensus about OSS ILS among the practiting librarians should be developed first.

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.

This experiment was conducted to elucidate the characteristics of dissolved oxygen uptake and germination of California rice varieties, L-202(Long grain), M-202(Medium grain), S-201(Short grain), Italiconaverneco(Long grain) and Korean variety, Hwaseongbyeo under $25^{\circ}C$ water condition. The distilled water was saturated with oxygen by using air pump for 2 hours. Dissolved oxygen uptake of rice seed was measured everyday by using the oxygen electrode during 4 days from soaking to coleoptile and radicle appearance. Total dissolved oxygen uptake was 211.7${\mu}g$ per grain in Italiconaverneco during that period 179.5${\mu}g$ in S-201, 144.3${\mu}g$ in Hwaseongbyeo, 140.4 in L-202, 135.8$\mu\textrm{g}$ in M-202. The ratio of coleoptile and radicle appearance showed the highest value in Italiconaverneco, and next were S-201 and L-202. The coleoptile and radicle showed the longest length in Italiconaverneco, and next were S-201 and Hwaseongbyeo.

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.
