The purposes of this study was to demonstrate the influence of fashion life-style, self-image and situational factors on consumer's apparel store choice for satisfaction of varied needs and high efficiency of marketing activity. A questionnaire was developed to measure research subjects based on theoretical study empirically. The questionnaire was administered to 270 women aged between 20 and 30 in Seoul. The results analyzed by factor analysis, cluster analysis, x2-test and oneway-anova. The results of empirical studies were summarized as follows: 1. Segmented groups of fashion life-style were classified practical/planning group, fashion- leader group, and shopping-oriented group. And store types which were prefered by those groups were department store/shopping center. 2. Segmented groups of self-image were classified actual-seeking group, modernity group and confidence group. And store types which were prefered by those groups were department store/shopping center. The Forecast of store choice on the base of self.image was showed that customers choose the store incongruous with self-image. But when it was analyzed each actual store choice. The Choice of high frequancy was congruous with self-image except for a specialty store/brand named outlet. 3. The significant differences could be found in choice of the store under particular purchase situations and especially at department stores and specialty store, their preference tended to be stronger as the degree of the store's involvement was hightened, but in the case of the generalization stores and the permanent discount stores, even though the degree of that involvement was low, their preference showed the same tendency.

The prevalence rate of psychiatric symptoms of the refractory epileptic patients was evaluated according to the location of the epileptic focus. The subjects were 91 patients admitted to Epilepsy Monitoring Unit of Seoul National University Hospital. The psychiatric symptoms were assessed by Korean version of Symptom Checklist-90-R(SCL-90-R). The locus of epileptic focus was assessed by clinical features, 2-hour interictal EEG, long-term video-EEG monitoring, brain MRI, interictal and ictal brain SPECT, and interictal brain PET The subjects were divided into three groups according to the epileptic focus, non-temporal(N=29), left temporal (N=26), and right temporal(N=32). There were no statistical differences in demographic and seizure-related variables among groups. The number of patients with $T-score {\geq} 65$ at any subscale of the SCL-90-R were compared by $X^2-test$ among groups. The mean T-scores of each subscale of the SCL-90-R were compared by oneway-ANOVA among groups. The prevalence rate of psychiatric symptoms of the refractory epileptic patients was 38.5%. There was no statistical difference in the prevalence rate of psychiatric symptoms among groups. However, the patients with non-temporal or right temporal epileptic foci showed statistically significant higher mean T-scores of interpersonal sensitivity, depression, hostility, and phobic subscales than the patients with left temporal epileptic foci. These results suggest that the epileptic focus plays an important role in the production of interictal psychiatric symptoms of the refractory epileptics.

Purpose: The association between pain and sleep is described as a vicious cycle and psychological distress is well known as comorbid condition in the patients with pain and sleep problems. The aim of the study was to evaluate the prevalence of self-reported sleep disturbance and its relationship to clinical and psychological profiles in temporomandibular disorder (TMD) patients. Methods: The sample consisted of 123 TMD patients (90 women and 33 men), with a mean age of $39.9{\pm}15.4years$. Self-report measures of sleep quality, pain and psychological profile were conducted via the Pittsburgh Sleep Quality Index (PSQI), the Brief Pain Inventory and the Symptom Checklist-90-Revision at the initial visit. The primary diagnosis of TMD were categorized as TMD with internal derangement without pain, TMD with joint pain, TMD with muscle pain and TMD with joint-muscle combined pain. The chi-square test, independent t-test, oneway ANOVA and multiple linear regression analysis were used for statistics. Results: The patients was grouped as good sleepers (n=32, scores of 5 and lower) and poor sleepers (n=91, scores of 6 and higher) according to the recommended cutoff point of the global PSQI score (>5). TMD patients with pain showed poor sleep quality than TMD patients with internal derangement without pain. Poor sleepers had high pain interference and elevated psychological distress. Among them, pain interference and depression were significant predictors to sleep quality. Conclusions: The results suggest that sleep disturbance is a prevalent complaint in TMD patients, and sleep problems in TMD patients are associated with pain and psychological distress.

Purpose: The aims of the present study are to determine the optimum compression rate in terms of file size reduction and diagnostic quality of the images after compression and evaluate the transmission speed of original or each compressed image. Materials and Methods: The material consisted of 24 extracted human premolars and molars. The occlusal surfaces and proximal surfaces of the teeth had a clinical disease spectrum that ranged from sound to varying degrees of fissure discoloration and cavitation. The images from Digora system were exported in TIFF and the images from conventional intraoral film were scanned and digitalized in TIFF by Nikon SF-200 scanner (Nikon, Japan). And six compression factors were chosen and applied on the basis of the results from a pilot study. The total number of images to be assessed were 336. Three radiologists assessed the occlusal and proximal surfaces of the teeth with 5-rank scale. Finally diagnosed as either sound or carious lesion by one expert oral pathologist. And sensitivity, specificity and k value for diagnostic agreement was calculated. Also the area (Az) values under the ROC curve were calculated and paired t-test and oneway ANOVA test was performed. Thereafter, transmission time of the image files of the each compression level was compared with that of the original image files. Results: No significant difference was found between original and the corresponding images up to 7% (1 : 14) compression ratio for both the occlusal and proximal caries (p<0.05). JPEG3 (1 : 14) image files are transmitted fast more than 10 times, maintained diagnostic information in image, compared with original image files. Conclusion: 1 : 14 compressed image file may be used instead of the original image and reduce storage needs and transmission time.

The restorations of the severely damaged teeth by post core have been increased with the developement of endodontic procedures. But high failure rates of these procedures being reported, various restorative modifications were induced for successful treatments. Cast post-core and prefabricated post with core buildups are choice of treatment. The main causes of failure of the restorations are the fracture of post and core, root fracture, and recurrent caries due to microleakage. Recently, the acid etching technique and the use of dentin bonding agent at tooth surface to reduce the possible microleakage at the tooth-restoration interfaces were introduced. The object of this study was to measure and compare the microleakage by the types and cementation methods of post-core. For this study, forty extracted human anterior teeth were selected for specimen. After cleansing and routine endodontic procedures, anatomic crowns of each specimen were removed at the level of 2mm above the cementoenamel junction. Canals were preparated for post insertion and specimens were divided into four groups randomly. Post-cores were fabricated according to method for each group. Microleakage was measured by length of dye penetration at the tooth-restoration interfaces with measuring microscope at 50 magnification. Oneway ANOVA and t-test were performed for statistical analysis of resulting data. The following results were obtained from this study. 1. There wert significant statistical differences in degree of microleakage between each group (p<0.01). 2. Cast post-core cemented with ZPC (Group I) showed the most severe microleakage pattern$(1.5547{\pm}0.0872mm)$, and cast post-core cemented with adhesive resin cement after tooth surface treatment with dentin bonding agent (Group II) showed the least microleakage $(0.1497{\pm}0.0872mm)$. 3. Group IV revealed less dye penetrations than group III, but no statistical significance was seen between two groups.

The purpose of this study is to examine how midlife working women's psychological well-being is associated with their reward/cost of family role and work role according to their kinds of job. For empirical research, 627 married working women living in Seoul, aged between 40-55 answered the structured questionnaire. The subjects consisted of 301 professional working women and 326 non-professional working women. The data were analysed by the frequencies, mean, oneway ANOVA, and multiple regression. The major findings were as follows 1) Two sub areas of midlife working women's psychological well-being-self esteem and life satisfaction-were higher than an average level. 2) The more midlife working women performed family role and work role, they perceived reward more than cost. 3) For the professional working women, the more they perceived the reward of family role and work role, the higher their psychological well-being was. The more they perceived the cost of family role and work role, the lower their psychological well-being was. These consequencies applied to not only general reward/cost of family role and work role but also interrole reward/cost between family role and work role. For the non-professional working women, general and interrole reward of family role and work role had the positive effects on psychological well-being. Their general cost of spouse role, general and interrole cost of mother role, general cost of work role had the negative erects on psychological well-being. However interrole cost between spouse role and work role did not have a significant effect on psychological well-being. Finally, the result of multiple regression analysis showed that general reward of work role had the largest positive effect on midwife working women's self-esteem. General reward/cost of spouse role had the largest effect on their life satisfaction.

We need to use aesthetic landscape assessment(ALA) as the means of riparian buffer zone(RBZ) management. This study verified the political validity of designation policy of RBZ and land purchase policy. The purpose of this study was to propose RBZ landscape management strategies through ALA of RBZ in Gyeongan Stream for the better attractive and healthy riparian landscapes. The natural type landscape units(LUs) covered 40.9% of the entire area and the cultivated land type LUs covered 20.58%. Landscape assessment consisted of landscape quality and landscape integration assessment. The criteria for assessing landscape quality(LQ) were naturalness, interest, uniqueness, and landscape function. LQ was ranked into five grades using a matrix. The landscape integration assessment consisted of an inner integration assessment in each LU and outer integration assessment among LUs. To review the propriety of designating the riparian area and the riparian ecological belt, differences in ecological appraisal and aesthetic valuation were reviewed through a t-test, Oneway ANOVA, and logistic analysis. The results of ALA, 29.15% of the entire area scored at grade 1 in LQ, while 31.95% scored at grade 5, indicating that grade 5 areas occupied a high share. Surveyed areas were divided into designated RBZ and undesignated RBZ. Results indicated that designated RBZ scored grade 1 in LQ took up 33.2% of the total, significantly higher than the 23.3% taken up by undesignated RBZ. When examined according to buffer distance, grade 1 areas within 50m took up 50.2% of the total area, lower than the 32.7% at buffer distances of 500m-1km. Results indicated a 1% statistically significant difference. Accordingly, analysis was undertaken for the expansion of designation of the riparian area and the selection of appropriate land for formation of a riparian ecological belt, and was designated at priority 1 and 2 for land purchase. This study can also contribute to the formation of a riverine eco-belt through discovery of design factors for upgrading the ecology, aesthetics, and landscape of the riparian area and application in determining land purchase priorities.
