The purpose of this study was to determine the gender differences in affecting factors of perceived stress level. The present study analyzed 2011 data of the Korea Community Health Survey and a total of 229,226 participants was included. To investigate the affecting factors of perceived stress, multiple logistic regression analyses were conducted. There were gender differences in affecting factors of perceived stress by education level, number of family members, household income, and self-care. This suggests that gender differences may exists between perceived stress level and health related quality of life. Further studies are necessary to investigate whether the cause of the gender differences in stress perception.

In information society, the need to detect document duplication and plagiarism is increasing. Many studies have progressed to meet such need, but there are limitations in increasing document duplication detection quality due to technological problem of natural language processing. Recently, some studies tried to increase the quality by applying syntatic-semantic analysis technique. But, the studies have the problem comparing syntactic-semantic trees. This paper develops a syntactic-semantic tree comparator, designs and implements a discriminator of similar documents using the comparator. To evaluate the system, we analyze the correlation between human discrimination and system discrimination with the comparator. This analysis shows that the proposed discrimination has good performance. We need to define the document type and improve the processing technique appropriate for each type.

Recently, the interests of mobile GIS technology is increasing with the spread of wireless network, the improvement of mobile device's performances, and the growth of demands about mobile services. Providing services in a wireless environment with existing wired-based GIS solutions have many limitations such as slow communication, processing rates and screen size. In this paper, we propose a cache algorithm on client side to solve the above problems. The proposed algorithm demonstrates the performance improvement over known studies by utilizing unit time and spatial proximity. In addition, this paper conducts a performance evaluation to measure the improvement in algorithm efficiency and analyzes the results of the performance evaluation. When spatial data queries are conducted, according to our performance evaluation, hit rate has been improved over the existing algorithms.

This paper analyzes cost tradeoffs between memory usage and computation for window-based operators in data stream environments. It identifies generic operator network constructs, and sets up a cost model for the estimation of the expected memory reduction and the computation overheads when window memory relocations are applied to each operator network construct. This cost model helps to identify the utility of window memory relocations. It also helps to apply window memory relocation to improve a query execution plan to save memory usage. The proposed approach contributes to expand the scope of query processing and optimization in data stream environments. It also provides a basis to develop a cost estimation model for the query optimization using window memory relocations.

This study focused on hospital quality of service to the customer service center into contact with the contents of the results were comprehensive evaluation. In this study, a variable that is committed, the hospital service quality and customer satisfaction, and relationships about reuse of the hospital, the hospital's strategic management could be because of the foundation. The study quality of hospital services and patient satisfaction, and reuse of the impact of the relationship between the quality of service in the hospital, the customet satisfaction, very significant according to the reuse of. A customer-centric future, these results provide guidelines for hospital management can be applied to further strengthen competitiveness are expected.

Ecotourism refers to tourism that senses and observes superior natural resources, cultural resources and history around. Today, as the current leisure patterns of the people change, a healing trip to find nature is being activated. In this paper, we propose a platform design and construction for providing ecotourism information. In the proposed platform, first, the image file of the eco-tourism objects taken every day from the image capture device is collected, converted into a video, uploaded to the server, then, when the tourist arrives at the eco-tourism object, It is designed to be able to watch.

One of the problems of panoramic image stitching methods is that its computational cost is so high that the image processing required usually cannot be done in real-time. Real-time performance is important in applications such as video surveillance becausewe must see current scenes. But it takes more than several seconds to calculate transform coefficients between images. Panoramic VR technologies such as Apple QuickTime VR have problem that distorts images of top and bottom. This paper presents a fast stitching method and a methpd reducing distortions of top and bottom in cubic panoramic image.

Using for the internet information is easy or difficult. The effort to obtain the useful information is developed the various technique such as search as well as the information repository, classification, processing and the utilization. Specially, such developments are remarkable to the Agent of various uses and the classification, conversion in processing techniques. The study introduces the classification service system of internet documents which is processing from the repository of internet information to the automatic classification and search service.

군의 교육훈련간 디브리핑과 피드백 장치 활용을 통한 심폐소생술 교육방법을 적용하여 보다 효과적인 교육 방법을 확인하고 심폐소생술 수행 전 후 피로도를 검사하여 심폐소생술 술기가 숙달된 인원과 숙달되지 않은 인원의 피로도 차이를 분석함으로써 심폐소생술 교육프로그램의 기초자료를 제공하고자 한다. 현재 야전에서 응급처치교육을 받은 적이 없는 비 의무병인자로 전투병 생존법 교육 소집 대상자 중 참여 희망자 50명을 대상으로 하였다. 연구방법은 3가지 교육방법(디브리핑, 피드백장치, 디브리핑과 피드백장치 조합) 을 적용한 3개의 그룹에서 1,2,3차의 평가와 전체 디브리핑을 통해 심폐소생술 수행능력의 질적 향상에 미치는 영향과 동일 대상 중 희망자 20명에 한하여 심폐소생술 수행(5분) 전 후 혈중 젖산 농도 측정 및 주관적인 문답(1~10점)을 통해 심폐소생술 수행에 따른 피로도 실험을 진행하였다. 3가지 교육방법에 따른 심폐소생술수행능력 향상은 모든 그룹에서 유의하였으며(p<.001), 그룹별 심폐소생술 수행능력 향상효과의 차이는 디브리핑과 피드백장치를 조합하여 적용한 그룹에서 유의하게 높았다(p<.01). 심폐소생술 수행능력이 숙달되기 전 후의 피로도에 대해서는 본인이 느끼는 피로도는 유의한 차이는 없었으나 혈중 젖산농도에 따른 피로도는 유의한 차이로 전보다 후가 낮아졌다(p<.01).

The present study investigated how culture and art education participants' outcome evaluation predicts the satisfaction of the education by performing the secondary analysis of the Korea Arts and Culture Education Service's (KACES) survey data. Exploratory factor analysis identified three dimensions(content, management, and resources) of education outcome evaluation, and the regression analysis revealed the factors of outcome evaluation influenced the education satisfaction positively. When the sample was grouped according to prior participation experience and companion [participated alone or with other person(s)], the regression analysis showed the differences of the influences between groups. On the basis of the findings, managerial implications for improvement of the culture and art education programs and suggestions for further studies were discussed.
