Due to the high compressive and tensile strength of ultra-high performance concrete (UHPC), UHPC used in steel concrete composite structures provided thinner concrete layer compared to ordinary concrete. This leaded to the headed stud shear connectors embedded in UHPC had a low aspect ratio. In order to systematic investigate the effect of headed stud with low aspect ratio on the structural behaviors of steel UHPC composite structure s this paper firstly carried out a test program consisted of twelve push out specimens. The effects of stud height, aspect ratio and reinforcement bars in UHPC on the structural behaviors of headed studs were investigated. The push out test results shows that the increasing of stud height did not obviously influence the structural behaviors of headed studs and the aspect ratio of 2.16 was proved enough to take full advantage of the headed stud strength. Based on the test results, the equation considering the contribution of weld collar was modified to predict the shear strength of headed stud embedded in UHPC. The modified equation could accurately predict the shear strength of headed stud by comparing with the experimental results. On the basis of push out test results, bending tests consisted of three steel UHPC composite slabs were conducted to investigate the effect of shear connection degree on the structural behaviors of composite slabs. The bending test results revealed that the shear connection degree had a significantly influence on the failure modes and ultimate resistance of composite slabs and composite slab with connection degree of 96% in s hear span exhibited a ductile failure accompanied by the tensile yield of steel plate and crushing of UHPC. Finally, analytical model based on the failure mode of composite slabs was proposed to predict the ultimate resistance of steel UHPC composite slabs with different shear connection degrees at the interface.

This study was carried out to investigate the eating out behaviors of adults in Jeonju area. A total of 500 adults were surveyed by questionnaires during January 2004. The subjects were aged 20 to over 50 years, and were classified into 4 groups (age $20{\sim}29,\;30{\sim}39,\;40{\sim}49$, and over 50). The data were analyzed using the SPSS 10.0 program. The results are summarized as follows: 78.2% of adults aged 50 and over answered they are 'eats three meals every day' (p<0.05). Breakfast was skipped in 73.3% of $20{\sim}29$ age group(p<0.001). As the age goes up, three meals and breakfast ratio were high. The highest frequency to dine out with a subjects were 2 or 3times a month(31.2%). About 40% of the $30{\sim}39$ age group spent daily $20,000{\sim}30,000$ Won for eating out. Korean foods were the most preferred menu for eating out in $40{\sim}49$ age group(p<0.001). Taste of food was the most important factor in selecting the menu (57.2%). Major source of restaurant information was recommendation by friends or relatives in $20{\sim}29$ age group(p<0.001). Dinner eat out was most frequent(45%) and lunch eat out on dinner eat out was 29%. Especially, 65.8% of $30{\sim}39$ age group was highest.

This study was conducted to analyse the dine out behaviors for single-person households using the Consumer Behavior Survey for Food in 2019. The results showed that the respondents had different dine out behaviors according to their age. 20s~30s and 40s~50s single-person household tend to dine out more frequently than 60s~70s. On the other hand, there was no significant difference in the most important selection criteria when choosing a restaurant (p=0.063), but 39.7% of 20s~30s 43.1% of 40s~50s, and the 38.3% of 60s~70s respondents selected 'the taste of food', and the young people (20s~30s) who chose 'cleanliness of the restaurant' were second with 39 people (15.5%), but in the opinion of 40s~50s and 60s~70s, 'price level' was the second most important selection criteria. Besides, frequency of buying food at home was the influencing factor for 20s~30s' monthly expenditure of dinning out, while frequency of buying food at home, monthly expenditure of buying delivery or take-out food were the factors for 40s~50s. Lastly, gender, occupation as well as monthly expenditure of buying delivery or take-out food were the factors for 60s~70s' monthly expenditure of dinning out. As many studies have shown that the expenditures single-person households play an important role in the restaurant business, the results of this study are necessary for food service industry to generate different business strategy to single-person household by age.

The purposes of this study were to investigate the effects of clothing values, self-perceived physical attractiveness on sensuous clothing behavior(see-through, body emphasis, body exposure, skinny), and also to figure out if any causal relationships existed among variables and whether demographic variables affected these relationships. For data collection, a questionnaire was administrated to 500 female college students in Gwangju City, Korea. The results were summarized as follows. First, clothing values were divided into six factors: religious clothing value, political clothing value, exploratory clothing value, social clothing value, economic clothing value, aesthetic clothing value. Sensuous clothing behaviors were divided into four factors: see-through, body emphasis, body exposure, skinny. Overall clothing values had positive effects on sensuous clothing behaviors. Second, self-perceived physical attractiveness turned out to have significant effects on overall sensuous clothing behaviors. Third, clothing values turned out to have significant effects on overall self-perceived physical attractiveness. This study confirmed that clothing values and self-perceived physical attractiveness turned out to have significant effects on sensuous clothing behavior.

The purposes of this study were to investigate the perception of nutrition labeling on restaurant menus, and to analyze the differences among subject's characteristics, eating-out behaviors, and dietary attitudes. Information concerning general characteristics, health status, eating-out behaviors and dietary attitudes of subjects was collected by a structured questionnaire. From January 5th to February 27th in 2009, 406 questionnaires were completed by 157 males and 249 females. Statistical analyses were performed using by SPSS 14.0 package program. The perception of the importance of nutrition labeling was 3.89, while knowledge of whether restaurants provided sufficient nutrition information scored 2.26 indicating that being highly conscious of nutrition labeling, respondents did not view the supplied information as sufficient. Nutritional perception was greater in females and varied in both genders with age and health status. Significant differences concerning the perceptions of nutrition labeling were evident, based on eating-out behaviors and dietary attitudes. The results imply that nutrition labeling on restaurant menus should be based on consumer characteristics. Relevant nutrition labeling might help improve health by encouraging proper dietary habits and providing valuable nutritional information. Recognition of the importance of nutrition labeling and strategic implementation of labeling in menus would be prudent strategies for restaurant managers.

Purpose: This cross-sectional study was designed to identify anger-expression types of adolescent women and investigate the relationship between the identified anger-expression types and their problem behaviors and suicide probability. Methods: The participants were 942 students at two female high school located in Gwangju. The data were analyzed using descriptive statistics, cluster analysis, t-test, ANOVA, and $Scheff{\acute{e}}$ multiple comparison test. Results: Cluster analysis revealed 4 distinct anger expression types; Anger-out, Low anger expression, Anger-control, and Anger-in/out types. Female adolescent women had a higher level of trait anger or who frequently used the anger-in/out type reported internalized-externalized problem behaviors and suicide probability more frequently compared to those who frequently used the other three types of anger expression. Conclusion: Female adolescent women who had the low anger expression type and anger control type managed anger most effectively. The findings suggest the necessity of a development of the program for lowering the trait anger level and controlling the unfavorable anger expression types such as the anger-in/out.

The purpose of this study is to find out how female immigrants are interested in beauty and how fashion affects their fashion management behavior. First, the correlation between interest in beauty and fashion behaviors showed that every factor has a positive relationship with each other. Self-interest, which is one of the two sub-factors of interest in beauty, showed a particularly strong correlation with interest in orientation towards fashion. Interest in appearance education, which is one of the two sub-factors of interest in fashion, showed a strong relationship with interest in orientation towards fashion, proving that the more one is interested in appearance-related education, the more she follows fashion trends. This suggests that caring for appearance and fashion trends have a strong relationship. Second, looking into the effect of interest in beauty and fashion on fashion behaviors, it turned out that only personal interest, out of the two sub-factors of interest in beauty, affected pursuit of fashion sense, out of the two sub-factors of fashion behaviors; interest in appearance education rather than interest in orientation towards fashion affected pursuit of fashion sense; interest in orientation towards fashion affected caring for one's appearance.
