  • Performed was a survey to find the level of interest on passenger services using IT and smart sensor technology in connection with High Speed Train development in Korea. The survey respondents were sampled from the KTX passengers, KTX crews, Korail employees, IT or sensor experts, and rolling stock experts. The results of the survey were categorized as importance, urgency/necessity, importance vs urgency/necessity, improvement measure, preferable activities based on the trip length, and inconveniencies. By analyzing the results, service items that can be implemented to the High Speed Train were recognized. The results showed that a passenger tends to expect to have his/her comfort and convenience, an attendant safety and serviceability, a Korail employee information provision and serviceability, an IT/sensor expert technological implementation done, and a rolling stock expert implementation done in practical level.

  • This study focuses on fashion adoption behavior of adolescents. The impact of their clothing involvement factors and socio-demographic factors on their fashion adoption behavior was examined. Three core issues were identified for empirical test: 1) Elements of clothing involvement for adolescents; 2) Fashion adoption behavior of adolescents; 3) Impact of clothing involvement elements on fashion adoption behavior. The Likert Type questionnaires were used to measure clothing involvement and fashion adoption behavior. The data of 472 samples drawn from middle and high school students in Taegu Metropolitan City were analyzed by factor analysis, ANOVA, Scheff test, t-test and regression analysis. Main results of the study are as follows. 1 . Concept of the clothing involvement is composed of five dimensions: importance, fashion, self-expression, pleasure, and buying risk. 2. Socio-demographic factors do influence fashion adoption behavior. Average monthly pocket money, expenditures on clothes and household income are found to have statistically significant impacts on the adoption behavior. Female students are more fashion-oriented than male students. 3. The clothing involvement elements are found to have significant influences on fashion adoption behavior: fashion, importance and self-expression elements on fashion innovation; fashion, importance and pleasure elements on fashion information search.

  • Well planned rehabilitation order of pipes is essential for efficient maintenance and management of Water Distribution Systems. In this study, not only deterioration rate of pipes but also structural and nonstructural failure which causes abnormal condition of WDS is considered to determine rehabilitation order. Probabilistic Neural Network is used for calculating deterioration rate at present and the importance of pipes is computed under structural and nonstructural failure by using Pipe by Pipe Failure Analysis and Effect Index. Utopian Approach, one of the Multi-Criteria Decision Making methods, is used for assessment of final rehabilitation order based on distance measure between utopian point and alternative one. Developed model in this study shows that it gives more reliable results than existing methods considering hydraulic relative importance does in application to real networks. In this point, the newly developed model, which gives advantages over existing models, can make a credible decision and simple application.

  • According to the results of Probabilistic Safety Assessment(PSA) for a Nuclear Power Plant(NPP), an Emergency Power Supply(EPS) system has been considered as one of the most important safety system. Especially, the interests in the reliability of the EPS system have been increased after the severe accidents of Fukushima Daiichi. Firstly, we performed the risk assessment and the importance analysis of the EPS system based on the PSA models of the reference plant, which is the Korean standard NPP type. Considering a portable Diesel Generator(DG) system as the reliability reinforcement of the EPS system, we modified the PSA models and performed the risk impact assessment and the importance analysis. Although the reliability of the potable DG could be about 20% of the reliability of the alternative AC DG, we identified that Core Damage Frequency(CDF) was decreased by at least 4.6%. In addition, the risk impacts due to the unavailability of the EPS system on CDF were decreased.

  • Purpose: The purpose of this study was to develop an instrument that evaluated QUality Of care Through patients' Eyes for hospitalized child (QUOTE-Child), and examine the validity and reliability. Methods: Preliminary items were reviewed through expert content validity and face validity. To test the validity and reliability of the instrument, the data were collected from 221 care givers of hospitalized children. Data were analyzed using exploratory factor analysis, Pearson correlation coefficient, Cronbach's alpha and Spearman-Brown coefficient. Results: Factor analysis yielded 19 items in four factors including 1) respect, 2) explanation, 3) kindness, and 4) skillfulness, with a cumulative explanatory variance of 70.68%. For criterion-related validity, a significant positive relationship was found between quality of care and pediatric family satisfaction. For internal consistency reliability, the Cronbach's ${\alpha}$ was .93 (importance) and .95 (performance) for the overall instrument. The half split reliabilities were .86, .95 (importance) and .92, .97 (performance). The Cronbach's ${\alpha}$ of 110 data was .92 (importance) and .94 (performance). Conclusion: Researchers and practitioners can use this instrument to systematically assess quality of care for hospitalized children and identify areas of support for hospitalized children and their family.

  • Although current RFID technologies can provide wide advantages in food industry area, most food companies do not consider willingly adopting this technology yet. This paper will present how the effective implementation of RFID systems in food industry could be realized. To Measure the importance of RFID systems, this study utilized the BMT(Bench Mark Test) methodology using RFID systems that were composed of tag and reader. After conducting this study, it suggests the effective tag attachment methods on the objects. The results are shown that the excellent tag product is a RFCamp and a fixed reader of Thingmagic Mercury 4 is the best product. Also, a portable reader of Motorola MC9090-RFID is recommend to the highest product. Therefore, this test is useful for selecting the best RFID systems to the food industry area. In addition, this study displays the effective tag attachment method to each bottle that was used to the experiments in food industry. Therefore, this study is contributed to the not only importance in the government IT areas as a growth engine but also the importance for consumer as a right for the knowledge about the food quality.
