  • Han-Bok presents a unique consumption ex-perience different from Western dress which is common to our clothing life. This study is intended to propose the necessity of broad-ening deepening and systematizing a research related to the social aspects of Han-bok. A questionnaire consisted of 10 statements of attitude to Han-Bok 7 statements of the evaluation of the occasional appropriateness of Han-Bok preference questions about style color harmony and decorative materials of han-Bok was developed which includes 5 opinion statement of the importance of tra-ditiona and some demographic variables. During December 1996 and January 1997 the women aged above 20 responded to it and finally 702 data was analyzed. Korean urban women have positive attitude to Han-Bok And the conceit about Han-Bok was significantly higher than the intention to wear it . The most properly evaluated occasion for wearing han-Bok was 'holdays' like Seolnal and chuseok Han-Bok was evaluated im-proper for casual wear and out wear. Factor analysis of 7 occasions determined 3 factors; traditional occasion special occasion and cas-ual occasion. It is needed to identify the ef-ficiency of Han-Bok according to each differ-ent occasion. Korean urban women preferred the style of traditional line soft color and modern har-mony. In a viewpoint of tradition they put more importance in the line of Han-Bok that they do in the color of it.

  • In this study, the flow characteristics at the ventilation holes was analyzed by using numerical method when carbon composite brake disk was rotated at a constant speed. In order to ensure the validity of the analysis results, grid dependency test was performed by considering the accuracy and appropriateness, and 4mm mesh size was selected for decrease of the maximum error rate 63.6%. As a result, the outside air flows in the clearance between the disk and shaft in case of B model. whereas, the outside air flows in the clearance or the outlet of the ventilation holes in case of A and C models. And also average static pressure at the outlet was changed depending on shape of the ventilation holes and rotational speed of the disk in case of A and C models. Besides, in the B model, intake air according to the clearance goes with side surface of ventilation hole, and so increased by mean velocity of 4.64m/s and mean pressure of 0.58pa in the ventilation hole outlet, in case of disk rotational speed of 146.21rad/s.

  • The concrete quality relies on general factors like preparation technique, uniformity of the compaction, amount and appropriateness of the additives. The current article investigates the impact of a well knows amino acid, L-arginine as an additive on water requirements, setting durations and characterization of various cement samples. Compressive strength tests of reference and L-arginine added cements at age of 2, 7 and 28 days were carried out according to TS-EN 196-1. Samples were blended by incorporating various amounts of L-arginine (25 ppm, 50 ppm and 75 ppm) in the cement water mixture which were tested with Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), thermo-gravimetric analysis (TG), scanning electron microscopy (SEM) and the energy-dispersive X-ray spectroscopy (EDS) on the 28th day. Results revealed that L-arginine does not affect the setting time, volume expansion of cement and water demands negatively; rather it imparts enhanced sustainability to the samples. It was determined that the highest value belonged to the 75L mortar with an increase of 2.6% compared to the reference sample when the compressive strengths of all mortars were compared on the 28th day. Besides, it has been observed that the development of calcium silicate hydrate or C-S-H gel, calcium hydroxide or CH and other hydrated products are associated with each other. L-arginine definitely has a contribution in the consumption of CH formed in the hydration process.

  • This study aimed to analyze the impact of importance and fulfillment(satisfaction) factors of menu quality on customers' intent of revisit of Japanese restaurants, so that it could provide information helpful to build up detailed marketing strategy and present considerations for management's higher sales amount and more efficient business results as well. Importance on menu quality scored higher level than fulfillment on the whole in Japanese restaurants. Notably, in regard to attributes of menu quality, it was found that respondents put higher stress on flavor, nutrition, cleanliness and freshness than anything else. In terms of IPA analysis on Japanese cuisine menu quality, it was noteworthy that the items with high importance but low fulfillment included menu price as an attribute for menu quality, although it was not shown in menu-specific items. In the survey on the associations between fulfillment(customer satisfaction) and intent of revisit, it was found that factors of customer satisfaction included 'trimness of dishes', 'information', 'appropriateness' and 'economic affordable' Out of these factors, it was noted that both 'trimness' and 'economic affordable' had significant effects on customer satisfaction at the significance level ranging from p<0.05 to p<0.001.

  • The purpose of this study is to grasp the effectiveness of evacuation safety design by verifying the appropriateness of the standard of occupant load factor for residential buildings. To this end, the definition and current standard of occupant load factor for residential buildings were analyzed, and the problems of the current standard were clarified by interviewing professionals. In addition, changes in occupant load factor were examined by year based on statistical research, and evaluation on the current standard $18.6m^2/pers.$ was performed. As for evaluation methods, the need of redesigning of evacuation capacity was investigated by using evacuation simulation. As a result of the analysis, the most serious problem was clarification of the applicable standard for residential officetel, where the average occupant load factor was $26.1m^2/pers.$, which was not appropriate. However, as a result of evaluation on evacuation capacity, although there was no difference between statistical research results and the current standard in terms of evacuation capacity, when the standard for business facilities was applied to officetel, evacuation time doubled. Thus, this study suggests that when the current standard is applied to residential officetel, it is necessary to separate between residential use and business use.

  • It is essential to measure load transfer mechanism of pile to check the appropriateness of assumptions made for design purpose and to continuously monitor the behavior of pile foundation. Through many attempts to monitor the behavior of super-structure in civil engineering area using several optical fiber sensors have been made, application of optical fiber sensor technology on pile foundation has not been tried up to now. Load transfer of model piles during compression loading was measured by optical fiber sensors and compared with the measurement by strain gauges. Fiber Bragg Grating(FBG) sensor system was used since it has many advantages, such as easy multiplexing, high sensitivity, and simple fabrication. Besides the model pile tests, uniaxial tension test of steel bar and compression tests of mortar specimen were carried out to evaluate the performance of FBG sensors in embedded environments. The shift of refilming wavelength due to the strain in FBG sensor is converted to the strain at sensor location and the dependence between them is 1.28 pm/${\mu}$ strain. FBG sensors embedded in model pile showed a better survivability than strain gauges. Measured results of load transfer by both FBG sensors and strain gauges were similar, but FBG sensors showed a smoother trend than those by strain gauge. Based on the results of model pile test, it was concluded that the use of FBG sensor for strain measurement in pile has a great potential for the analysis of pile load transfer.

  • In order to analyze possible effects of senior hospital selection factors and service satisfaction on senior hospital patients' revisit of senior hospital, this study surveyed guardians of total 204 patients hospitalized in major 4 senior hospitals in Busan. As a result, this study came to the following conclusions: First, it was found that guardians considered appropriateness of medical treatment cost as the biggest factor of choice, which was followed by kindness of doctor and hospital employees, locational accessibility (traffic convenience), and doctor's medical capacity. Second, the factor analysis about patients' satisfaction showed that the influential factors consisted of satisfaction at medical staffs, satisfaction at nursing and care, and satisfaction at facilities. Third, there was not significant difference in the overall impression of hospital and the intention of revisit depending upon sociological variables. Fourth, satisfaction at nursing and care and satisfaction at facilities had significant effects on better satisfaction at overall impression of hospital, and it was noted that the shorter admission period and the less complaint led to the higher intention of revisit. Therefore, it is necessary to improve satisfaction at medical staffs, nursing and care, and facilities rather than patients' own sociological characteristics.

  • This paper describes the weldability and mechanical behavior of JIS S45C medium carbon steel (corresponding to KS SM45C and SAE 1045) for machine structures in CW Nd:YAG laser welding. ill general, medium carbon steels have a limited application to the industrial fields in spite of good mechanical characteristics. This is due to welding difficulty because of the high carbon contents and impurities in this material. Therefore, in this study the laser weldability of medium carbon steel with adjusted contents of S and P has been investigated in order to extend the application to medium carbon steels. Several experiments and numerical simulations have been conducted to determine the characteristics of mechanical behavior in CW Nd:YAG laser welds. The results of the simulations concur with the experiment results. From the result of this study, the application possibility of CW Nd:YAG laser welding to medium carbon steel has been confirmed. Also, the appropriateness of mechanical behavior simulation has been verified to analyze and predict the welding phenomena.
