Recently, improvement of the quality of urban riverscape environment has been emphasized not only by landscape architectural field but also by various professionals in planning and ecology. Regarding to this current movement, the aim of this paper is to highlight major visual elements of riverscape axis as a case study of Shinchon River in Taegu City to suggest some basic guidelines for arranging riverscape in urban area. The study was mainly based on Repertory Grid Development method which was developed in Japan. The method is consist of three steps such as decision of element landscape in study area for slide photos, selection of evaluation items for interview and obstraction of proper evaluation factors. The major findings through this study are as follows; 1) The 12 major visual elements which possibly improve riverscape, based on abstraction of proper evaluation factors, are Dunchi, surface of the water,, equipment of river, buildings near riverside, river vertical and horizontal facilities like bridge, fine view, riverbed, water plant, naturalness, water's edge line, harmony and street trees by order. 2) Total numbers of adjective which describe 12 common factors are 25, such as clean, open, stable, quiet, comfortable, friendly, bright, natural etc. In addition, Dunchi was described 337 times by various adjectives, surface of the water was 200 times and arrangement of river was 146 times which is similar result with the order of 12 influential common factors. 3) Therefore, Dunchi, surface of the water and equipment of river are three most important factors which could create better riverscape. These three factors implies us how we supply good quality of urban river environment for the urban residents.

The etiopathogenesis of burning mouth syndrome (BMS) seems to be complex and many patients probably involves interactions among local, systemic, and/or psychological factors in the pathophysiologic mechanism. Although there are controversies over whether the psychological factor is a cause or a result of BMS, several studies have supported strong relationships between psychological factors and chronic pain. It has been suggested that somatic complaints from unfavorable life experiences may influence both individual personality and mood changes; however, initiation of BMS symptoms is not necessarily correlated with stressful life events despite their elevated psychological stress. If the psychological distress is not a causal factor of BMS, it seems that BMS patients may be particularly vulnerable to psychological problems, primarily depression, anxiety, and hostility due to the characteristic entities of BMS such as chronic persistent pain itself. It seems likely that both physiological and psychological factors play a role in causing, perpetuating and/or exacerbating BMS; therefore, both two components of the patient's symptoms must be addressed. The acceptance of psychological factors by the patient is often an important element of BMS, management. The evaluation of psychological and emotional status of BMS patient enables clinicians to recognize prolonged negative and subclinical factors which can complicate the management of pain or indirectly perpetuate other physical factors. This evaluation improves the doctor-patient relationships, motivation, and compliance through a correct understanding of the clinical problem. Appropriate emotional and psychological evaluation may be required prior to developing a treatment plan in order to gain the successful treatment outcome.

This paper aims to apply two ways of student evaluation, i.e. peer- and self-evaluation to TBL(team based learning) class and to explore the difference between two evaluations by gender and grade as well as their relationships, and finally to provide an explanation for the improvement of evaluation ways in TBL class. There has been much research about TBL and its related factors. However, according to the examination of both domestic and overseas researches concerning the application of peer- and self-evaluation to TBL class, few studies have focused on them in terms of the engineering curriculum. This study was conducted with 251 engineering students at P University, and peer- and self-evaluation in TBL class have been measured. Our findings show that firstly, there were significant grade differences in self-evaluation of engineering students. Second, there were no significant gender and grade differences in peer-evaluation. Third, we found a significant correlation between the two factors, self- and peer-evaluation. Also there was a significant correlation among variables of subcategories. Based on these findings, it is expected to provide an explanation for the application of peer- and self-evaluation in TBL class and will be useful for the improvement plans of the related courses in engineering school.

This study analyzed the effects of demographic factors and sensory experiences of customers on customer satisfaction, using data from 302 customers in the Pusan, Ulsan, and Kyungnam areas who have visited family restaurants within 3 month period prior to the study. This study defined the sub-factors of sensory experience as vision, sound, smell, taste, and touch, and defined the sub-factors of customer satisfaction as main services, supplementary facilities, services related to sales promotion, served food, and the location of a restaurant. The study revealed that each evaluation score of the sub-factors of sensory experience and each evaluation score of the sub-factors of customer satisfaction was a little higher than the middle score. Respondents evaluated taste as the highest score among the sub-factors of sensory experience and evaluated main services as the highest score among the sub-factors of customer satisfaction. In terms of the effects of the sub-factors of sensory experiences and demographic factors on overall customer satisfaction, more positive taste experience, vision experience, and sound experience led to higher overall customer satisfaction and the married group in terms of marital state gave higher evaluation scores on overall customer satisfaction than the counterpart. In terms of the effects of the sub-factors of sensory experiences and demographic factors on individual customer satisfaction, consumers' sensory experiences were shown to exert far greater influences than the demographic variables.

The problem of system reliability is very important issue in the digitalized nuclear power plant, because the failure of its system brings about extravagant economic loss, environment destruction, and fatal damage of human. Therefore the purpose of this study has developed the reliability evaluation model through the scoring model by the quantitative and qualitative factors in order to justify the evaluation considering the advanced safety factors in the Advanced Pressurized water Reactor 1400MWe(APR 1400MWe) under uncertainty. Especially, the qualitative factors considering the human, information control, and quality factors for the systematic and rational justification have been closely analyzed. The proposed model can be simply applied in real fields in order to minimize the industrial accidents in the digitalized nuclear power plant.

The purpose of this study is described in detail as follows. First, I would like to define what digital transformation is in the maritime transport sector. Second, it is intended to derive success factors for digital transformation in the maritime transportation field by examining various preceding studies related to digital transformation. Finally, in order to derive priorities for the derived success factors, an AHP analysis model is built and an expert survey is conducted for practical experts in the maritime transportation field. Based on the survey results, we would like to provide guidelines on what factors should be considered first among the success factors of digital transformation in the maritime transportation sector. In this study, in order to derive the priority of success factors for digital transformation in the maritime transportation field, the hierarchical structure was divided into four high-level evaluation items(strategic factors, organizational culture and human factors, technology factors, and environmental factors) and 21 sub-evaluation items. A relative evaluation method of weighting items among AHP(Analytic Hierarchy Process) was applied. AHP analysis of 24 questionnaires with a consistency ratio of 0.1 or less in order to increase the accuracy of information among questionnaires collected through maritime transportation related university professors, research groups, shipping companies, container terminals, and experts engaged in shipping related IT companies was carried out. As a result of the analysis, the priority of the first-tier factors for the success factors of digital transformation in the maritime transport sector was shown in the order of strategic factors, organizational culture and human factors, technology factors, and environmental factors. In addition, when looking at the priorities of 21 detailed items, it was found that the development of new business models, the creation of an active future digital strategy, and the leadership of the chief digital officer were high.

In this study, I tried to provide the basic data for planning the public library space to meet the new needs of the users in digital generation by survey and literature review on factors in planning the digital space of public libraries. In 2000, a separate space for digital materials has been prepared at the most of the libraries as a part of informatization program of public libraries. However, it is not sufficient to provide a number of different needs of the users due to the identical design of all the libraries. For the prioritization, 50 factors have been deducted by review of preceding studies, evaluation factors and criteria of library of each institution. Factorial analysis was performed on the factors with the importance which was higher than average. Also, the relationships among the factors with similar properties were understood to categorize the factors in space planning by each factor. Based on these factors in planning the digital space, further space evaluation of the public library and user satisfaction survey could be followed to provide a fundamental basis for the specific space planning.

System Intergration (SI) has resently been conceived as one df the most important tools for enforciong and reinforcing the competitiveness of an enterprise. A major concern of SI lies in sharing many types of information, such as engineering, production, finance, marketing, and so on. Product Data Management (PDM) systems are mainly concerned with product- related information, and also support a large portion of the Commerce At Light Speed (CALS) straitegy. PDM systems receive a great amount df attention form industry, A variety of PDM solutions have been introduced for the last few years, and its market has expanded very fast with an annual growth of 30%. However, in general, it is not an easy task to choose a right PDM solution for a particular company. A major purpose of this paper is to provide essential factors in evaluating PDM systems. While developing the factors. we consider the expected future trend of PDM technologies and three types of PDM-based intergration (frontward, rearward, and sideward integrations). We Propose to carry out the evaluation process in two fold. An overall evaluation is performed first to narrow down many alternatives into a few candidate systems, and then a detailed technical evaluation step follows to determine the final solution. A number of influencing factors are categorized and described in each of these steps.
