Infrared thermography is one of the most valuable and cost-effective diagnostic techniques for predictive maintenance on electrical systems. For the electric installations, the thermographies can identify major problems, which if left unattended could lead to breakdowns. The result thermal images depend upon operator skills, inspection technique, and load and weather conditions. When the thermographer is applied to remote monitoring, the conditions of the systems are not perfectly analyzed because operators are hard to know the weather's effects of the installed place. Therefore, this paper defines the effects by weather conditions which will influence the final results. The purpose of this paper is to define the weather effects that a thermographer needs to consider for successful condition analysis.

Data mining technology is frequently used in identifying the intention of users over a variety of information contexts. Since relevant terms are mainly hidden in text data, it is necessary to extract them. Quantification is required in order to interpret user preference in association with other structured data. This paper proposes rating and comments mining to identify user priority and obtain improved ratings. Structured data (location and rating) and unstructured data (comments) are collected and priority is derived by analyzing statistics and employing TF-IDF. In addition, the improved ratings are generated by applying priority categories based on materialized ratings through Sentiment-Oriented Point-wise Mutual Information (SO-PMI)-based emotion analysis. In this paper, an experiment was carried out by collecting ratings and comments on "place" and by applying them. We confirmed that the proposed mining method is 1.2 times better than the conventional methods that do not reflect priorities and that the performance is improved to almost 2 times when the number to be predicted is small.

Background: The purpose of this study were to identify the physical therapist's turnover experience in Busan Metropolitan city and its related general factors, and to investigate the turnover, moving-in and out rate. Methods: First Data were collected from 102 physical therapists who working in Busan Metropolitan city using structured questionnaires and then second data collected from who call to directly. Results: Physical therapists expressed high level of turnover experience. Physical therapist's turnover experience was significantly different by their age, marital status, sex, working place and career. In proportion of the total increasing rate of physical therapist and turnover rate was increased. Conclusion: To prevent or reduce physical therapist's turnover rate, more research about causal relationships of physical therapist's turnover should studied.

This paper presents a technology of information data fusion between radar and ELINT electronic intelligence system. adar get the information of the range, direction and velocity of targets, and ELINT system get the information of the direction and angular velocity of the same targets at the same place and at the same time. Since we have some common information data of targets from radar and ELINT system, we can find the target on radar is same or not on ELINT system using the information data fusions. If the target on the radar is verified with the same target on ELINT system, we get more information of the target. e can analysis and identify the target exactly and reduce an ambiguity error of unknown targets.

Due to the explosive growth of smartphone use, new type and format of business opportunity is being created. Despite the creation of added value using smartphone is very important, the past study on smart phone has been mainly focused on its functions and specifications. This study is intended to identify the factors that influence continuance usage intention of smartphone and to analyze the relationship between such factors and the expected confirmation. satisfaction, and usage intention. The result of this empirical study indicates that the perceived enjoyfulness and quality significantly affect users' expected confirmation and satisfaction, and social influence also affects users' continuance usage intention. Thus, it implies users place a high value on enjoyfulness and quality in using smartphone application and on social influence in choosing specific application. Finally this paper provides a detailed account of how customers accept smartphone application and their perceived characteristics affect the usage intention.

We installed the measurement equipment which measure the equivalent Salt Deposit Density(ESDD) of the domestic coast area in the selected 112 place and investigated the influence of the wind which blow at the point of 500m from coast installing a wind vane, wind gauge for realtime measurement. During september${\sim}$december, 2005, ESDD which passively measured at the point of 50m from coast is maximum C grade in the Homigot of Pohang, B grade in the Gochang and A grade in the remaining point. Also ESDD which is measured in the east coast, west coast respectively is the more the distance being far from the coast to inland, the more ESDD rapidly decreasing but each area of the south coast is difficult to identify the decreased tendency because of very low measurements.

본 연구는 지난 30여 년 동안 두 번의 신도시개발 정책으로 인하여 이원적 도시구조를 지니게 된 성남시의 차별적 생성과 변화를 행위주체자로서 여성을 선택하여 그들의 생활세계-생활사, 사회.경제적 배경, 지역정체성, 지역사회의 관계, 일상과 생활공간-를 통하여 공간과 사회와의 관계에서 경험적으로 입증하고자 하였다. 그 결과 성남시는 차별성을 지닌 두 지역사회를 생성하게 되었으며, 각 장소의 행위주체자(여성)의 생활세계에 있어서도 차별적 특성을 나타내어 기존시가지 주부들은 신시가지에 <가까이 하려는> 경향을, 신시간지 주부들는 <구별짓기>의 경향을 나타내고 있었다. 또한 전업주부의 일상생활을 통해서 볼 때 기존시가지의 경우에는 오전에는 주로 부업활동에, 오후에는 주변 이웃과의 교제활동을 주로 함으로써 자신의 거주지를 생산현장으로서의 공간으로 형성해 가고 있는 반면 신시가지 주부들은 오전에는 사적인 생활 즉 여가활동에, 오후에는 자녀교육활동에 참여하는 등 자신의 거주지를 소비현장으로서의 공간으로 형성해 가고 있었다.

We examine the major factors governing the travel time for commuters in the Seoul metropolitan area. To identify the determinants of the commuting time for residents with jobs in the city centre, a multiple regression analysis is performed using household survey data. The results reveal that commuters in Seoul place higher value on time than on living space. Thus, we may conclude that recent trends in income segregation in Seoul are not the result of increased housing demand but of dispersed jobs and better amenities offered in the suburbs.

People in the advanced society have deep interest in such environmental problems as noise, air quality, water pollution, etc. This paper submits the result of the research on the noise In the surroundings of the butane can explosion location. First, the noise level measured in a residential area, 245 meters' away from the butane can explosion location, was 59.3 dB. Also, the noise level measured in the IGUP (International Graduate University of Peace), 300 meters' away from the explosion site, was 52.5 dB. Second, the above noise levels are lower than the level specified In the Environmental Standard (65 dB), which represented that the experiment was safe. Third, the noise level in a place away from the butane can explosion location varied in accordance with the direction of the wind. Consequently, the noise in all locations (the places where damage to people is expected) surrounding the experimental butane can explosion location was measured to identify the effect of the wind irection.

Purpose: The purpose of this study was to identify the factors that affect nursing students' perception of pediatric safety nursing activities for children during hospitalization. Methods: The study sample included 304 nursing students who had participated in pediatric nursing practice. Data were analyzed using SAS 9.3 program. Results: Regression analysis showed that the model's explanatory power was 37%. Safety policy and procedure, safety priority, disaster experience, and knowing a place of refuge were factors affecting the perception of safety nursing activities for children during hospitalization. Conclusion: Findings show that safety policy and procedures and safety priority are major factors that affect the perception of safety nursing activities and indicate that effective education programs on safety policy and procedure and safety priority are necessary to improve the perception of safety nursing activities.
