It has been recognized for decades that the spherical bearing which is sliding on curved surface in the intrinsic behavior is optimized for the railway bridge requiring a large slope deflection. However, the spherical bearing is easily corrosived at the PSC girder bridge which is exposed to the outside so the normal function of bridge bearing is not fulfilled fully. It is common that the corrosion is happened at the operating plate of steel bridge bearing and generally it is necessary to replace the bridge bearing after 20~25 years. Accordingly, It costs multi billion dollars for maintenance each year and the necessity of improvement become a issue. Korea Rail Network Authority(KR) suggested to apply the Elastomeric bearing instead of Spherical bearing through the task of construction site of 2006. But the normal Elastomeric bearing is optimized for the Highway bridge so it needs the special consideration to satisfy each design condition required by railway bridge. As the result of examination of Elastomeric bearing at the railway bridge construction site, the stress is decreased by effective dispersion of earthquakes and the maintenance fee is also decreased.

Due to the development of technology, urbanization, industrialization, etd. at modern times, even the individual view of value has changed in variety. That means the change of each consumcer's life-style and even that of propensity to consume. In that regard, the modern, commercial space became to be increasingly included to specialization and complication. Such specialization and complication of the commercial space can be thought to be a positive response of enterprises to satisfy the needs or desire of consumers who become diversified. In this study, some new models in the method of the planning and designing of the S.I.P(Shop Identity Program). intended to research into as follows ; - As the background of the advent of the multi-used shopping complex, changes in consumer life-style and propensity to consume according to social and economical changes were intended to be studied through various statistical data literature. - For the study of the characteristics, constituent conditions, and planning operation of the future multi used shopping complex in the marketing aspect of enterprises, it was intended to study centered on the theory of consumer behavior and that of retail marketing. - In the process of the spatial design of the multi-used shopping complex, it was tried that a designing process to materialize a target of the discrimination and orderly arrangement of stores be progressed. In the process of materializing a target based on both corporate image and 'brand' image in designing.

Demand forecasting is one of the most critical tasks in defense logistics, because the failure of the task can bring about a huge waste of budget. Up to date, ROK-MND(Republic of Korea - Ministry of National Defense) has analyzed past component consumption data with time-series techniques to predict each component's demand. However, the accuracy of the prediction still needs to be improved. In our study, we attempted to find consumption pattern using data mining techniques. We gathered an 18,476 component consumption data first, and then derived diverse features to utilize them in identification of demanding patterns in the consumption data. The results show that our approach improves demand forecasting with higher accuracy.

While graduates of Japan's technical high schools might demonstrate skills in a given specialty, they would be hard-pressed in any attempt to pass national universities' notorious entrance examinations. In a collaborative effort begun in 1994, the faculties of engineering at Niigata, Nagasaki, and Toyama Universities set about the task of preparing entrance examinations, and a general curriculum geared to the needs and educational backgrounds of these students, offering them supplementary lessons. While the larger project officially ended in 1999, we are carrying the research forward in Niigata University.

This research focuses on the cadastre and cartographic tradition regarding the representation of Rome that had lasted until the middle of 18th Century. Since the early period of Roman Republic until the early 18th Century, map was considered as a effective medium to record the status of urban facts and also a manifestation of changing perception of reality. These facts allow to diagnose social and conventional changes that had occurred in the field of representation techniques and methodologies derived from diverse intention and objective in elaboration of each map. Cartography also has affinity to architectural drawing as many categories of individuals are involved, clients, researchers, craftsmen, publisher and collectors. Fundamental task of documenting the contemporary physical reality was given to the map, however, as architects had practiced through the drawings, cartographers also reconstruct in subjective way specific buildings and urban aspects according to various needs and demands. As such, philology and imagination play important role as two constitute extreme poles in the evolution of the cadastre. Through analysis of paradigmatic examples in the genealogy of cartography of Rome, it was possible to understand the changing episteme that testify the mentality and custom in the field of visual representation.

The remote operation of the Advanced Spent Fuel Conditioning Process (ACP) is analyzed by using the 3D graphic simulation tools. The ACP equipment operates in intense radiation fields as well as in a high temperature. Thus, the equipment should be designed in consideration of the remote handling and maintenance. As well as suitable remote handling and maintenance method needs to be provided. To provide such remote operation technology, we developed the graphic simulator which provides the capability of verifying the remote operability of the ACP without fabrication of the process equipment. In other words, by applying virtual reality to the remote maintenance operation, a remote operation task can be simulated in a computer, not in a real environment. In this way the graphic simulator can substantially reduce the design cost of the remote operation process and the equipment. Also it can provide new operation concept that is more reliable, easier to implement, and easier to understand.

This article explores how we pursue and operate the English medium instruction(EMI) in engineering colleges so as to educate global engineers. Engineering students in the 21st century society need to have fundamental work in languages, cultural differences, and strategies for working with diverse colleagues. EMI is not sufficient for preparing our engineering students to cope with the changed environments in our globalized society. Based on the case study, we emphasize that EMI needs to be located in the context of global engineering education which demands our understanding of different cultures and communication practices. We also suggest some programs how we develop our EMI circumstances.

The aim of this study was to investigate school dieticians' awareness of the necessity for nutritional education and job satisfaction via qualitative research. For this purpose, in-depth interviews were carried out with 10 school dieticians. Results revealed that all participants said that schools urgently need nutritional education, and dietary attitude and unbalanced eating habits were the most urgent matters to be addressed. They made various suggestions related to revitalization of nutritional education: turning dieticians into nutritional educators, improving awareness of teachers and parents, receiving training on appropriate teaching methods, and so on. In response to their tasks, they considered bargaining with vendors and examination foods as the most burdensome tasks. In response to questions about how participants were treated in their workplaces, all participants reported low job satisfaction due to excessive work, lack of promotion opportunities, and low salary. To improve this, participants recommended creating a task manual, strengthening their role as managers, increasing their salary, and so on. Therefore, institutional support is necessary for dieticians to efficiently handle their excessive workload. In addition, an educational environment where dieticians can effectively carry out nutritional education needs to be created.

Purpose: This study aimed to determine the levels of burnout, self-efficacy, intention to stay, and organizational citizenship behavior (OCB) among nurses in small- and medium-sized hospitals, and factors related to nurses' OCB. Methods: A targeted sampling method was adopted, whereby 185 clinical nurses employed at 1 of 4 hospitals were enrolled in the study. OCB was measured with a tool developed by Podsaoff et al. Associated factors, including nurses' general characteristics, burnout, self-efficacy, and intention to stay, were measured using a structured survey. Data were analyzed by frequencies, t-test, ANOVA, Duncan's multiple test, Pearson Correlation Coefficient and multiple stepwise regression. Results: Levels of OCB in nurses was on average 3.52 on a scale of 1 to 5, exhibiting a positive correlation with self-efficacy and intention to stay, and a negative correlation with burnout. The final related factors were self-efficacy, burnout and intention to stay with a predictive and explanatory power of 52% for OCB. Conclusion: To increase the level of OCB of nurses, an environment in which such behavior is encouraged needs to be established by introducing measures related to administrative support and task efficiency that reduces mental burnout, while increasing self-efficacy and intention to stay.

Enormous methods have been proposed for the detection and segmentation of blur and non-blur regions of the images. Due to the limited available information about the blur type, scenario and the level of blurriness, detection and segmentation is a challenging task. Hence, the performance of the blur measure operators is an essential factor and needs improvement to attain perfection. In this paper, we propose an effective blur measure based on the local binary pattern (LBP) with the adaptive threshold for blur detection. The sharpness metric developed based on LBP uses a fixed threshold irrespective of the blur type and level which may not be suitable for images with large variations in imaging conditions and blur type and level. Contradictory, the proposed measure uses an adaptive threshold for each image based on the image and the blur properties to generate an improved sharpness metric. The adaptive threshold is computed based on the model learned through the support vector machine (SVM). The performance of the proposed method is evaluated using a well-known dataset and compared with five state-of-the-art methods. The comparative analysis reveals that the proposed method performs significantly better qualitatively and quantitatively against all the methods.
