문서적 특성을 갖는 XML을 위한 데이터 모델에 관한 연구
이강우 한라대학교 2006 論文集 Vol.9 No.-
As XML is considered as a standard to represent and exchange data on the web, there are many researches to develop applications based on XML Along with these trends, many researches are on going to develop the techniques on storing and searching XML documents But the data models in these researches mainly focus data-centric XML and cannot support document-centric XML fully A data model for document-centric XML document is proposed in this paper Using the proposed model, it is possible to represent the semantic and structural information of XML document fully And a algebra for the proposed model is also proposed as the foundation for query language and query processing
DMZ 지역특성에 따른 관광객의 참여동기와 만족도 : 철원ㆍ연천과 양구ㆍ고성지역을 대상으로
이강우 경기대학교 관광종합연구소 2014 여가관광연구 Vol.22 No.-
한반도 생태평화벨트 DMZ 일원은 안보 및 역사문화 관광자원뿐만 아니라 생태환경까지 잘 보존되어 있고 국내외적으로 새롭게 조명되고 있을 뿐만 아니라 더 나아가 이를 기반으로 세계 자연유산등록을 추진하는 등 세계적인 관광자원으로써의 가치가 있다. DMZ관광 체험객들이 인직하는 참여동기를 구성하는 요인은 “특수성”, “역사설”, “모험성”으로 나타나 DMZ관광을 향 후 어떠한 방향으로 설정할 것인가에 대하여 제시하였다. 본 연구는 DMZ관광에 대하여 참여동기와 만족도에 대하여 지역간 차이가 있는 것을 규명하 여, DMZ관광에 실무적으로 적용될 수 있다고 판단되고, 향후 DMZ관광을 이해하는 방향에 대 하여 또 다른 관점에서 제시하였다고 볼 수 있다.

This study purposed to research on the technique system of Jeongdosul. To accomplish of this purpose, I collected and examined many documents which covered the composition of technique, principle and the skill name of Jeongdosul and have get the result as follows. Firstly, Jeongdosul is general martial arts composed of bare-handed and weaponry martial arts. Secondly, Jeongdosul have involved unlimitedness on the base of the principle of battle. Thirdly, Jeongdosul have actual technique in the principle of battle aspect. Fourthly, Jeongdosul is a traditional Korean martial arts based on the indigenous Korean thought. These days they are concerned highly that the essential value of the martial arts being extinct because martial arts mostly being enacted in the frame of sports. In terms of a discovery of the new traditional martial arts I feel importance of this study. 이 연구는 정도술의 기술체계에 내재 된 무술로서의 가치와 의미를 재조명하고 후속 연구를 위한기초자료를 제공하는 데 목적을 둔다. 연구목적에 따라 정도술의 기술과 원리, 명칭에 관련된 다양한 문헌을 수집하고 분석하여 도달한 결과는 다음과 같다. 첫째, 정도술은 무기사용 여부와 무기종류에 따라 다양한 기법의 맨손 무술과 각종 무기술로 구성된 종합무술이다. 둘째, 경기화 과정을 경험하지 못한 정도술은 공방의 원리와 기법상 무제한성을 내포하고 있다. 셋째, 정도술은 호신술, 건신술, 출하술 등이 융합된 실용적 무술이다. 넷째, 정도술은 인본주의, 삼재삼신과 자연동화 등 우리나라 고유의 사상을 기반으로 한 전통무술이다. 오늘날 대부분의 동양 무술이 스포츠의 틀 속에서행해짐으로써 무술의 본질적 가치가 상실되어 가고 있다는 우려의 목소리가 높아지고 있다. 점점 쇠퇴해 가는 전통무술과 그 가치에 대한 새로운 발견이라는 점에서 본 연구의 중요성을 깨닫게 한다.

The purpose of this study s to find the effective method to increase physical performance in female college students by comparing the effects of resistance and plyometric exercise on leg strength and endurance. The subjects consisted of untrained female college students(n=16, aged 20-25years), were distributed into resistance training exercise group(n=8) and plyometric exercise group(n=8). Both groups participated in the resistance training and plyometric exercise program respectively, 2times per weak during 12weeks. Repeated measures ANOVA was used for statistical analysis. The results of this study are following. 1. There was significant differences between groups in the test of 1-RM leg strength after 12weaks training. 2. Ther was significant differences between groups in the test of leg endurance after 12weeks training.

This research was performed in order to investigate the correlation among organic pollutant indices of non-biodegradable paper wastewater. As a result of investigating the BODU of paper wastewater, the CODCr and BODU values of DIP-wastewater and influent water respectively are similar in values. In the case of influent water, the concentration changes of BODU of paper wastewater show a typical form of BODU, a study on the effluent water was in a form of non-purified wastewater of BODU. A study on the soluble substances from influent paper waste water make up approximately 10% of entire influent water the value for effluent water resulted to be 19%. It was investigated that soluble substances from paper wastewater contain non-biodegradable organic substances in large amounts. The oxidation (TOC/CODCr) value of paper wastewater came out to be very high for both influent water and effluent water. As for influent water, in DIP-wastewater the value for non-biodegradable organic substances (TOC/CODMn) was higher than that for biodegradable organic substances in initial wastewater the value for biodegradable organic substances (TOC/BOD) came out to be higher. A study on the biodegradability (CODCr/BOD) of influent water (pulp and initial) showed that a biological treatment is possible, and a study on effluent water showed that it contains a significant amount of non-biodegradable organic substances (CODMn/BOD). As a result of an analysis of properties of non-biodegradable organic substances as a function of time, it is possible to remove non-biodegradable organic substances after longer periods of remaining.

In general, an optimal inventory policy is sensitive to the form of inventory costs, demands of goods and delivery times of each stock point, so that until now types of inventory policies have examined and studied for several authors, i.e. Fred Hannssman, M. M. Connors and Summer Aggarwal. The inventory model analyzed in this paper assumes a Series-type Multi-stage Inventory Model with emergency handling of shortages at a premium cost. In the model demands and delivery times of each stock point are respectively defined as a normal distribution and an arbitrary probability distribution. We show at first a criterion for selecting the optimal ordering points and ordering quantities of each stock point is formulated by maximizing the expected profit per unit time, and then an algorithm for computing the optimal ordering points and ordering quantities in the model. Finally, we will design a simulation model and show the results of simulation and a sensitivity analysis for our model.

These studies were performed to evaluate the serum levels of mumps specific IgG antibody in term pregnant women and their neonates (umbilical cord sera), in unvaccinated infants and vaccinated children using enzyme linked immunosorbent assay (ELISA). The sera were collected from 44 pairs of pregnant woman and neonate, 103 unvaccinated infants and 491 vaccinated children. In this context, the author attempted to demonstrate the transplacental transfer rate of maternal mumps specific IgG, the changes of the IgG levels in unvaccinated infants, and in various age groups of vaccinated children. The results obtained were as follows. 1. There were significant correlation between maternal and neonatal umbilical cord sera in mumps specific IgG level (correlation coefficient r=0.856, p<0.001), and the mean antibody level of neonates was 1.2 times higher than that of the mothers (p<0.05). 2. The seropositivities and levels of mumps specific IgG decreased by infantile ages, 50.0% in 2-3 months, 6.7% in 4-5 months and 0% after 6 months of age respectively. 3. The mean seropositivity of mumps specific IgG was 90.5% in vaccinees aged 1.5 to 12 years, but those of 1.5-6 years were lower than 80%. The mumps specific IgG levels significantly increased with age (r=0.328, p<0.001). 4. The mean seropositivity of mumps specific IgG was 80.6% in vaccinated adolescents age. These results showed that seropositivities of mumps specific IgG of vaccinated preschool children was lower than expected level, and it partially explained the reasons for mumps epidemics recently in Korea. Also above results may apply on planning the current vaccination schedules of mumps vaccine.
