To evaluate customer satisfaction of hotel food and beverage products, developing items for the measurement is necessary through studying the properties of food and beverage products. The properties consist of human service, physical and systematic service. Human service includes appearance and uniforms, courtesy and kindness, quickness and precision of the service, well-educatedness, moral sense and etc. Physical service includes the taste of food and beverage, diversity of food and beverage, outlets' cleanness and atmosphere, refinement of fixture, furnishing and table ware, the admission passage to the hotel and parking lot facilities, and etc. Systematic service includes passages of movement to outlet, arrangement of outlet, reservation management system, operation of events and package goods, temperature and ventilation system and etc. The price is also one of important variables to measure customer satisfaction index, so it is included to the investigating items. As shown some hotels have several satisfactory items but most items are unsatisfactory because expected service is better than perceived service. Therefore, the hotels which lack human service need the reinforcement of service education, the hotels which lack physical and systematic services need the improvement, the development and the renovation according to the unsatisfactory items. And the hotels whose price item is unsatisfactory need to consider the policy.

The phenomena of high-voltage polarization and conductivity in oriented vinylidenefluoride and tetrafluoroethylene copolymer films have been investigated. It was shown that under certain electric fields, injection of carriers from the material of electrodes appears The barrier for holes injection in the copolymer was found to be lower than that for electrons. It results in more effective screening of the external field near the anode than near cathode. Electrones, ejected from cathode, creating negative charge by trapping on the surface. It is shown that the electrons injected from cathodes create a negative homocharge on the copolymer surface and then become captured on the surface shallow traps. Their nature has been studied by the x-ray photoelectron spectroscopy. It was shown that these traps may consist of chemical defects in the form of new functional groups formed by reactions of surface macromolecules with sputtered atoms of aluminum. The asymmetric shape of hysteresis curves was explained by the difference in mobility of injected holes and electrons. These factors caused appearance of "non-closed" hysteresis curves for fluorine-containing polymer ferroelectrics. Hysteresis phenomena observed at low electric fields (below coercive ones) are to associate with the behavior of the domains localized in the ordered regions formed during secondary crystallization of copolymers.

The purpose of this study was to investigate the influences of adolescents' body image and communication with their parents on the alienation of male and female middle school students. The subjects were 253 middle school students. The data were analyzed with SPSS win 18.0 using Cronbach's ${\alpha}$, t-test, one-way ANOVA, Scheff$\acute{e}$ test and stepwise regression. The findings showed that problematic communication with the father was the strongest factor in explaining the alienation of male middle school students. The second strongest factor was the middles school student's open communication with the mother, and the third strongest factor was the middle school student's perception of physical health. Unlike male students, open communication with the father was the strongest factor in explaining the alienation of female middle school students. Problematic communication with the mother was the second strongest factor. Perception of physical appearance was the third strongest, and perception of physical health was the fourth strongest factor. Based on the results of the study, implications were discussed in terms of the alienation of male and female middle school students.

We describe a case of a 71-year-old male patient who experienced progressive bilateral proximal upper limb weakness and atrophy without sensory symptoms and signs over 5 years. Electromyography demonstrated denervation potentials and neuropathic motor unit action potentials on C5-C7 myotome muscles bilaterally. Cervical spine magnetic resonance imaging revealed engorged anterior epidural venous plexus, T2 hyperintensity localized to grey matter ("snake-eye" appearance) at C2-C6 vertebral level, and ventral epidural fluid collection from C6 to T8 vertebral level. This case indicates that bibrachial amyotrophy associated with epidural fluid leak should be suspected in patients presenting with progressive bilateral upper limb weakness and atrophy without sensory involvement.

The purposes of this study were to segment adolescents into groups by family and school factors and to investigate the differences among the groups regarding body image and self-esteem. The study distributed the questionnaires to the adolescents who were middle and high school students in South Korea. The total respondents were 2240. The data were analyzed by factor analysis, cluster analysis, ANOVA, Duncan test, and $X^2-test$. Factor analysis showed that body image had four dimensions: appearance management, physical attractiveness, weight control, and the opposite sex fear. The cluster analysis showed that Korean adolescents were segmented into four groups (family preference/school preference group, family dissatisfaction/school dissatisfaction group, family average/peer competition group, family average/peer dissatisfaction group). The four groups were significantly different in regard to three dimensions of body image, self-esteem, and demographics. For example, the family preference/school preference group was most satisfied with their bodies, had a lowest opposite sex fear, and had a highest self·esteem. However, family dissatisfaction/teacher dissatisfaction group was most dissatisfied with their bodies, had a greatest interest in their appearance, and had a lowest self-esteem.

The purpose of this study is to suggest a guidance to select proper muslin through investigating fabric characteristics. The structural and physical properties of muslin and top fabric samples were tested by KES-FB system and other testers. And in order to examine the relation between fabric characteristics and the shape of garments, wearing tests were done with jackets made of those samples. As a result, bending rigidity(B), bending hysteresis(2HB), shear stiffness(G), shear hysteresis at=0.5(2HG), shear hysteresis at=5(2HG5), stiffness, cloth count/5cm, weight, thickness were extracted as the key factors affecting the appearance of garments. To have similar appearance, all of these should be counted. After standardizing, we calculate the variance between top cloth and muslin. And from this we could get the range that the proper muslin should be included. The ranges were as follows: Bending rigidity(B): within 0.024g.$\textrm{cm}^2$/cm(0.3$\sigma$); Shear stiffness(G): within 2.21g/cm.degree(1.3$\sigma$) Weight: within 9.33mg/$\textrm{cm}^2$(18$\sigma$); Thickness: within 0.20mm(1.8$\sigma$)

Properties of textile fabrics influence the appearance, aesthetics, and performance of garment. Drape and related properties of fabrics affect profoundly the static and dynamic appearance during wearer's movement. The three dimensional shape of the folded structure often deforms with time or with subtle vibration around the fabric specimen during the drape measurement. Due to the uneven and complex nature of fabrics, the overall shape of the fabric specimen on the drape tester often becomes unstable. There is a need to understand the fundamental mechanisms of how draping may generate pleasing forms. Two drape test methods, conventional Cusick drape test, and in-built drape tester, based on a depth camera, are compared. Fabric specimens including cotton, linen, silk, wool, polyester, and rayon are investigated for the fabric drape and other physical/mechanical parameters. Drape coefficient values of fabric specimens are compared based on the final drape images, together with the intermediate 3D drape images of the specimens during elevation process of the drape tester equipped with a stepper motor system. The correlation coefficient between the data based on the two methods is reasonably high. Another advantage from the depth camera system is that it allows further analysis of three-dimensional information regarding the fabric drape shape, including the shape of nodes or crest and trough.

This study explored various issues related to the quality-of-life for obese Korean men. In-depth interviews were conducted with thirty men over BMI 25 whose age ranged from 20's to 50's. Projective techniques along with semi-structured interviews were used. The results of interviews were analyzed based on grounded theory. "Stress" was the main phenomenon resulting from the causal conditions of obesity and stigma. Stress consisted of social, psychological, physical and environmental factors. Contextual conditions mediating the relationship between causal conditions and main phenomenon were obesity level, pressure, and public appearance. Avoidance, change of personal traits, and insensitivity were the action/reactions to the main phenomenon. Various factors due to obesity disappeared and quality-of-life increased when they succeed in weight reduction; however, factors related to obesity and lowered condition of quality-of-life continued if they experienced a weight gain/loss yo-yo.

In the variation of physical properties of adhesive fabrics, the objective of this study is to analyze fitness of fusible interlining to four sorts of fabrics for men's suit with various structural parameters. Four fusible interlinings are used for adhering to fabrics for men's suit. Mechanical properties of these 16 adhesive fabrics fused with these interlinings are measured by KES-FB system for analysing appearance and wearing properties of garments and for examining the fitness of fusible interlining to the fabrics for men's suit. The variation of bending property for adhesive fabrics are found to be higher in the order of interlining 1(Cotton30/Rayon70, plain), interlining 2(Polyester30/Rayon70, warp knit), interlining 4(Polyester, shingosen fabrics with drawing textured yarn) and interlining 3(Polyester, double dot coating interlining). The variation of adhesive effect shows the same results with bending property and shows negative relation with extensibility in weft direction per extensibility in warp direction(EM2/EM1). The variation of peel strength of adhesive fabrics, woolen fabrics in the case of face fabrics and interlining 3 in the case of interlining shows the largest value respectively.
