Boar sperminogen was purified from the acid extracts of the washed epididymal spermatozoa by gel filtration through a Sephadex G-100 column, followed by preparative SDS-PAGE. The 32 kDa sperminogen band was sliced out from the preparative SDS-PAGE and 32 kDa sperminogen was eluted from the gel matrix. The purified 32 kDa sperminogen was subjected to amino acid composition analysis. The amino acid composition of the 32 kDa boar sperminogen showed significant differences from that of either boar proacrosin or ${\beta}-acrosin$, which signifies that 32 kDa sperminogen might not be a breakdown product of proacrosin-acrosin system and that the 32 kDa sperminogen is a different protein from proacrosin-acrosin system.

IEC 61850은 변전소 자동화 시스템에 관한 국제표준문서이다. IEC 61850의 특징의 중의 하나로서 GOOSE가 있다. GOOSE는 변전소기기 간에 빠르고 신뢰성을 보장하여 기기들 간의 정보교환을 위한 IEC 61850 통신 서비스이다. IED는 GOOSE 메시지를 통해 트립 신호와 같은 중요한 정보를 전송한다. 현재 몇몇의 IEC 651850 기반의 기기들이 개발되었고, 한국에서는 IEC 61850 기반의 IED를 개발하고 있다. IEC 61850 표준문서에서 오류, 모호한 점 그리고 추가할 점들이 발견되고 있다. 이러한 문제들은 Technical Issues라 부른다. 이 논문은 IED 개발업자 또는 검사자에게 IEC 61850과 관련된 좀 더 나은 이해와 견해를 제공하기 위하여 GOOSE에 관한 기술적 이슈를 조사한다.

The software development process (SDP) plays an important basic role in software engineering education. Every software is developed in accordance with a specific SDP which contains all phases of software development. SDP education helps students to understand the overall techniques and the process of software engineering. This paper introduces a software development methodology (i.e., process) - 'OOPT (Object Oriented Process with Traceability),' which was proposed for use in university software engineering classes. The OOPT is based on object-oriented software development, and it defines concrete requirements as well as outputs of each process/phases. It also contains the unit/system testing and a traceability analysis. We have used the OOPT in software engineering classes at Konkuk university for eight years. This paper conveys our experience as well as future extension and improvement plans.

Objectives : While there are many studies about treatments of facial palsy, no study has been performed on general population of Korea, especially concerning about comparison between western medicine and oriental medicine. This study aimed to investigate magnitude of health visits and treatment patterns for Korean patients with facial palsy through the computerized database of Health Insurance Review and Assessment Service(HIRAS). Methods : According to the HIRAS database over 5 years' period from 2004 to 2008, the medical records of patients with facial palsy as a main diagnosis were extracted. Inclusion criteria of facial palsy are Bell's palsy(G510), Geniculate ganglionitis(G511), Melkersson's syndrome(G512), Other disorders of facial nerve(G518), Disorder of facial nerve, unspecified(G519) in western medicine. And Paralytic face(G016), Deviated eye and mouth(J01), The other facial palsy(J013) were included in oriental medicine. We compared the claim number of western medical care with that of oriental medicine treatment by year and month. Results : The total claim number of facial palsy was increasing on both western medicine and oriental medicine from 2004 to 2008. In western medicine, the claim number of Bell's palsy(G510) is the most. In oriental medicine the inpatients claim number of Deviated eye and mouth(J01) is the most, while outpatients claim number of the other facial palsy(J013) is the most. Conclusions : Medical database of HIRAS provided comprehensive and vast information on epidemiologic characteristics and treatment, which can be more reliable data to expect medical demand for facial palsy in condition that accurate diagnosis and standardized treatment is delivered in clinical settings.

The Goon-rearrangement in 1914 caused a significant change in the Goon office buildings' construction in the Japanese colonial period. The aim of this study was to discover the administrative procedure for the construction of them around the Goon-rearrangement and also in the 1910s generally, the Japanese government-general's policy for the construction and the buildings' condition. This study analyzes the official documents for the Goon-rearrangement between the Japanese government-general of Korea and the To, the digital images of the buildings kept in the National Archive of Korea and the newspapers published in 1910s. This paper examines what the effect the construction had under the stance of the Japanese government-general of Korea, which was very passive regarding the construction of new buildings.

It is important to speed up the loading time of web applications. Parsing is a loading process that contributes to an increased loading time. To address this issue, the optimization called Concurrent Parsing has been proposed which handles the parsing process in parallel by using additional threads. However, Concurrent Parsing has a limitation that it does not consider the priority order of parsing. In this paper, we propose heuristics that exploit priorities of parsing to improve the Concurrent Parsing. For parsing priority, we empirically investigate the sequence of function calls, classify functions into 3 categories, and extract function call probabilities. If a function has high call probability, we give a high priority and if a function has low probability, we give a low priority. We evaluate this priority heuristics on real web applications and get the 2.6% decrease of loading time on average.

Purpose: The purpose of this study was to identify the degree and correlations between the nursing image and professionalism perceived by male and female nursing students in College. Method: The subjects were composed of 683 nursing students (male 59, female 624) in college located in Gyeonggi province using convenience sampling method. Descriptive statistics, Pearson correlation coefficient and t-test were used for data analysis. Results: The mean score of nursing image perceived by male nursing students was 3.80 (${\pm}0.51$) and that of female nursing students was 3.75 (${\pm}0.45$). The mean score of professionalism perceived by male nursing students was 3.61 (${\pm}0.55$) and that of female nursing students was 3.64 (${\pm}0.42$). There was no significant difference between nursing image of male and female students in statistical analysis (t=1.38, p=.248). And there was no significant difference between professionalism of male and female students in statistical analysis (t=1.73, p=.167). The nursing image perceived by male nursing students was positively related to professionalism (r=.74, p<.001). The nursing image perceived by female nursing students was positively related to professionalism (r=.69, p<.001). Conclusion: Based on the results of the study, further research is needed to change of perspectives on new educational approach to male nursing students.

Plantago asiatica L., observed frequently in East Asia, is a known herb used in traditional medical remedies several studies report that P. asiatica L has anti-inflammatory and antioxidant effects. To determine the production of cytokines (IL-2, $IFN-{\gamma}$, and $TNF-{\alpha}$) induced by lipopolysaccharide (LPS) and non-LPS-stimulated macrophages, an ELISA assay was conducted using cytokine kits. Mice splenocytes were cultured for 48 h with various concentrations of P. asiatica L. (5, 10, 50, 100, 250, 500, and $1,000{\mu}g/mL$) or with mitogens (ConA or LPS). P. asiatica L. increased the proliferation of mice splenocytes, especially under the condition of its concentration ranging from 250 to $1,000{\mu}g/mL$. In addition, Plantago asiatica L. notably induced cytokine production of (IL-2, $IFN-{\gamma}$, and $TNF-{\alpha}$) at its concentration of $250{\sim}500{\mu}g/mL$. These results suggest that supplementation with P. asiatica L. water extracts may play a potential role in enhancing immune function by mediating splenocyte proliferation and cytokine production through its anti-inflammatory activit.

For using Global Navigation Satellite System(GNSS) in the civil aviation, it should satisfies the Required Navigation Performances(RNPs) which are defined by International Civil Aviation Organization(ICAO). RNP defines the required accuracy, integrity, availability, continuity of each flight procedure. In order to guarantee user's integrity, user's protection level has to be overestimated. On the other hand, for improving user's availability, user's protection level has to be estimated tightly. Therefore protection level should be estimated as tight as possible while it assuring the user's integrity. This paper describes the current integrity function of Korean WAD GNSS test bed, and predicts the availability performance of Korean WAD GNSS by simulation.
