The purpose of this study is to investigate the visual illusions and image of the combinated collars and sleeves which are combinated by the computer simulation. The detail object of this study as follows; 1) to know the visual illusions of the clothing as the collar and sleeves are combinated 2) to constract the clothing image using sementic differential scales 3) to know the differet image of the clothing as the collars and sleeves are combinted 4) to know the interaction effect of the collars and sleeves of the clothing The detail method of this study is as follows; In the first experiment, there are two groups; the first 8 groups are the combination of the same collar and the different sleeves. The second 8 groups are the combination of the same sleeve and the different collars. The second experiment has done for the 32 clothings which are the combination of the 8 collars and 4 sleeves. For the 14 clothing the image has tested by 13 semantic differential bi- polar scale. The subjects were 50 female students majoring in clothing and textile. The data analyzed by Kendall cofficient of concodance, Factor analysis, Anova and scheffe's test. Briefly the image of the clothing is much influenced by the varing of the collar than that of the sleeve. Thus, we also can conclude that the recognition of the clothing are much more dependent on the collar than sleeve.

Objectives: The purpose of the study was to examine the influencing factors of oral health-related quality of life in adults. Methods: A self-reported questionnaire was completed by 300 adults in Seoul and Gyeonggido from June to July, 2015 by convenience sampling method. Except 19 incomplete answers, 281 data were analyzed by t test, one way ANOVA, Pearson's correlation coefficient analysis, and multiple linear regression analysis using SPSS 18.0 program. The questionnaire consisted of general characteristics of the subjects, health-related characteristics, whole body dry symptoms and subjective perception of dry mouth. The oral health-related quality of life was measured by Likert five points scale, and a higher score indicated a lower quality of life. Results: The oral health-related quality of life in adult varied by age, systemic diseases, oral health status, missing tooth, stress, decayed tooth, gingival disease. The oral health-related quality of life had positive correlations with the subjective perception of dry mouth and whole body dry symptoms. The subjective perception of dry mouth(${\beta}$=0.245) had the influence on the oral health-related quality of life, oral health status(${\beta}$=-0.209), gingival disease(${\beta}$=-0.151), and decayed tooth(${\beta}$=-0.146) in order. Conclusions: The oral health-related quality of life was closely related to the subjective perception of dry mouth and the oral health status. It is necessary to develop the quality of life improvement programs including oral health prevention and care program in the adults.

Protective behavior of radiological technologists against radiation exposure is important to achieve reduction of the patient doses without compromising medical achievements. This study attempts to provide a basic model for the sophisticated intervention strategy that increases the level of the protective behavior of the technologists. The model was applied to real situations in Korea to demonstrate its utility. The results of this study are summarized as follows: First, the protective environment showed the highest relationship in the factors considered, r=0.637 (p<0.01). Secondly, the important factors were protective environment in environment characteristics, expectation for the protective behavior 0.228 (p<0.001), self-efficacy 0.142 (p<0.001), and attitude for the protective behavior 0.178 (p<0.001) in personal characteristics, and daily patient -0.112 (p<0.001) and number of the participation in the education session for the protective behavior 0.074 (p<0.05). Thirdly, the final protective behavior model by a path analysis method had direct influence on the attitude 0.171 (p<0.01) and environment 0.405 (p<0.01) for the protective behavior, self efficacy 0.122 (p<0.01), expectation for the protective behavior 0.16 (p<0.01), and self-efficacy in the specialty of projects 0.154 (p<0.01). The acceptance of the model determined by the absolute fit index (GFI), 0.969, and by the incremental fit index (CFI), 0.943, showed very significant levels. Value of $x^2$/df that is a factor applied to verify the acceptance of the model was 37, which implies that the result can be accepted in the desirable range. In addition, the parsimonious fit index configured by AGFI (0.890) and TLI (0.852) was also considered as a scale that accepts the model in practical applications. In case of the establishment of some specific intervention strategies based on the protective behavior model against harmful radiation effects proposed in this study, the strategy will provide an effective way to prevent medical harmful radiation effects that could cause severe injuries to people.

This paper is concerned with evaluating the fidelity of a non-cognitive test adaptation for use in multiple languages and cultures using two differential item functioning(DIF) techniques: (a) PSIBTEST, and (b) Logistic Discriminant Function Analysis(LDFA). In particular, this study focused on how DIF research can best be extended to the problem of evaluating the equivalence of tests across cultures and languages. The Sixteen Personality Factor (16PF) questionnaire was administered in English to 844 American college students and in Korean to 538 Korean college students. This study attempted to identify the best matching criterion for the translated tests by using both a multivariate matching technique and iterative purification process. The results generally showed a small number of DIF items on each scale, except for scales A and N where about half of the items showed DIF. The choice of matching variables based on a combination of internal measures appeared to have little effect and the iterative purification method was unsuccessful. Finally, the results were discussed and methodological implications were also presented.

The effect of small-scale near surface inhomogeneity on Rayleigh wave propagation and dispersion has been investigated in this study using two-dimensional FEM elastic modeling. Various inhomogeneity models with a variety of geometrical shape and embedment depth which exist in homogeneous half-space and two-layered media are considered. Results show that any near surface inhomogeneity greater than one wavelength in terms of minimum wavelength of Rayleigh wave shows dispersion characteristics. Such dispersion effect become stronger as the dimensions of the inhomogeneity increase. The effect of horizontal dimension is more dominant factor governing the dispersion characteristics than vertical dimension. However, the dispersion effect can not be identifiable in seismogram if the horizontal dimension is not wide enough. Nonetheless, even in this case, the existence of inhomogeneity can be inferred by the reflection or transmission event of Rayleigh wave. The results can be expected to provide insights on the behavior of Rayleigh wave which may be helpful for designating field work or new processing scheme to detect near surface inhomogeneity by surface wave method.

The purpose of this study was to assess Korean and non-Korean customers' preferences with regards to Korean foods as well as their opinions concerning the commercialization of Korean foods. The subjects consisted of 268 Koreans and 217 non-Koreans in Seoul, Gyeonggi and Daejeon, Korea and in Texas in the United States. The respondents were asked to assess their preferences regarding 22 Korean food items using a 5-point scale (1: strongly dislike - 5: strongly like). Excluding responses with significant missing data, there were 485 usable responses. Data were analyzed using SPSS Windows (ver. 14.0) for descriptive analysis and t-test. Korean customers' perception and preferences regarding Korean foods were significantly higher than those of non-Korean customers (p<0.001). Among the 22 Korean food items, Galbi-gui (4.32) was chosen to be Koreans' favorite menu, whereas Bulgogi (4.25) was most preferred by non-Koreans. Patjuk was the least preferred by Koreans (3.37) and non-Koreans (3.18) alike. Regarding convenience food product equivalents of the 22 Korean foods, Koreans thought Bibimbap to be the bestseller while non-Koreans thought that Bulgogi was the most sold product. Korean and non-Korean mostly wanted to purchase Bibimbap and Bulgogi respectively, if Korean foods are commercialized as a convenience food. Koreans (44.4%) and non-Koreans (66.8%) reported "taste" as the most important factor when choosing a convenience food. Koreans chose "salty taste" (26.9%) and "simple cooking method" (23.1%), whereas non-Koreans chose "nutrition" (23.5%) and "hot taste" (21.2%) as aspects that require improvement in order to commercialize Korean foods.

This research has four specific objectives: (1) identifying factors that affect customer satisfaction with less than container load (LCL) cargo services of logistics companies in HoChiMinh City (HCMC), (2) measuring the level of impact of the factors, (3) testing the difference in satisfaction among groups of customers with different characteristics in terms of type of business and time of using LCL cargo services, and (4) proposing some management implications to improve the quality of LCL cargo services. Researchers interviewed 210 customers who enjoyed the LCL cargo service in HCMC for at least the last six months, using the convenient sampling method. SPSS 20 was used to analyze the reliability of the scale through the Cronbach's alpha coefficient, then exploratory factor analysis and multiple linear regression analysis were used. The results identified the six factors that influence positively customer satisfaction of LCL cargo services of logistics companies in HCMC, by decreasing importance: service process, image, resource, price, management, and outcomes. The results show that there is no difference in customer satisfaction with LCL cargo services by types of business as well as time of using services. The research suggests some implications for the management of logistics companies in HCMC to enhance customer satisfaction.

This study was to investigate the level of fatigue and its associated variables in patients with systemic lupus erythematosus(SLE) in Korea. From March to June, 2001, 100 patients, registered at one university hospital rheumatology clinic in Seoul, were accepted as subjects for this study. The sampling method was adopted a non-probability, purposive technique. The instruments used for this study were The Multidimensional Assessment Fatigue scale developed by Tack and Beck Depression Instrument develped by Beck. The collected data were analyzed by SAS program using t-test, ANOVA with Scheffe-test, Pearson correlation coefficients and stepwise multiple regression. The results were as follows: 1. Total scores of fatigue of the subjects averaged $24.46(\pm10.85)$, degree of fatigue was $5.08(\pm2.29)$, and influence of fatigue was $3.52(\pm2.12)$. 2. Regarding characteristics, more depressive(p=.0001) and more painfuI(p=.0122) patients revealed more fatigue. Also, the subjects with spouse(p=.0337) and having poor quality of sleep(p=.0445) revealed more fatigue. 3. The subjects' total fatigue score, depression, pain and age was correlated positively(r=.53; r=.48; r=.24), and total fatigue score, and exercise time, quality of sleep was correlated negatively(r=-.45; r=-.21). 4. The main influencing factors on the fatigue were depression$(52.92\%)$ and quality of sleep $(8.10\%)$. These two main variables made it possible to explain $61.02\%$ of the varience in fatigue. In conclusion, this study revealed depression and quality of sleep is an important factor that can improve quality of life in patients with SLE. It is recommended that nursing intervention for SLE patients would be focused to decrease depression and to enhance quality of sleep.

Background: Inferior alveolar nerve block (IANB) of the mandible is commonly used in the oral cavity as an anesthetic technique for dental procedures. This study evaluated the success rate of the first IANB administered by dental practitioners. Methods: Volunteer dental practitioners at Mahidol University who had never performed an INAB carried out 106 INAB procedures. The practitioners were divided into 12 groups with their advisors by randomized control trials. We recorded the success rate via pain visual analog scale (VAS) scores. Results: A large percentage of the dental practitioners (85.26%) used the standard method to locate the anatomical landmarks, injecting the local anesthetic at the correct position, with the barrel of the syringe parallel to the occlusal plane of the mandibular teeth. Further, 68.42% of the dental practitioners injected the local anesthetic on the right side by using the left index finger for retraction. The onset time was approximately 0-5 mins for nearly half of the dental practitioners (47.37% for subjective onset and 43.16% for objective onset), while the duration of the IANB was approximately 240-300 minutes (36.84%) after the initiation of numbness. Moreover, the VAS pain scores were $2.5{\pm}1.85$ and $2.1{\pm}1.8$ while injecting and delivering local anesthesia, respectively. Conclusions: The only recorded factor that affected the success of the local anesthetic was the administering practitioner. This reinforces the notion that local anesthesia administration is a technique-sensitive procedure.
