An analytical simulation of the flexural behavior of SFRC beam has been illustrated. Curvature distributions and crack opening in critical region were taken into account. Compressive and tensile constitutive models which express post-peak behavior of SFRC with stress-crack opening relationships were incorporated in simulating nonlinear flexural behavior of the beam. The model was able to predict test results with reasonable accuracy. Behavior of the critical section and effects of different factors m the flexural behavior of SFRC beam were investigated. Simple observation and statistical approach have been made in selecting most influential parameters in flexural behavior of SFRC.

This study was conducted to provide current information on dietary behaviors and dish preferences of elementary school children and to suggest guidelines for proper dietary behaviors. To accomplish study objectives survey was executed using the questionnaire for 420 fifth and sixth grade school children, chosen from schools in Kangwha-gun and East River District of Seoul. A questionnaire largely consists of categories including general characteristics, dietary behavior and preferences of the subjects for some dishes. Results showed 30％ of the subjects had breakfast irregularly. A majority of the subjects took Korean style dishes of cooked rice and soup for breakfast. fifty-eight percent of subjects had a regular meal time. Imbalanced diet(avoiding specific flood group thereby causing unbalance in nutrient intake) habit group was estimated to be 47.3%. Twenty one percent had a habit of overeating. In choosing the snack, taste was considered to be a more important factor than nutrition. Advertisement of the snack was shown to be one of the Important factors in selecting the snack. The girls were more concerned about weight control than the boys. Also the girls were likely to rely on the diet to control weight since they exercised only in the physical c1ass while the boys exercised regularly. Generally, children liked animal protein containing foods and the preference for vegetables was low. In order to improve overall dietary behavior, systematic nutrition education programs reflecting sex difference should be developed. Dish preference data would be very useful in selecting substitutive dish for the s[hoof lunch menu to improve imbalanced diet. (J Community Nutrition3(2) : 69∼76, 2001)

Purpose - The present study examines interrelationships among antecedent factors defining consumer behavior in selecting online shopping websites. Research design, data, and methodology - The study identified factors from existing literature and used Interpretive Structural Modeling (ISM) to propose a conceptual approach to explain consumer website selection behavior. Through extensive discussions among industry and academia experts, qualitative assessment of the relationship between various factors was determined. Results - According to the model, eight congregating factors do not converge directly for website selection, rather, they operate following a hierarchy of influence. The ISM and MICMAC analysis reveal that information on a website and website aesthetics play key roles in influencing website selection. However, convenience and the value proposition also play very significant roles. Conclusions - The study's findings can help the e-commerce industry, especially online retailers. The findings can be used to enhance e-retailer ability to attract, communicate, engage, achieve, monitor, and evaluate web traffic and design appropriate strategies. The study's prime contribution is the application of Interpretative Structural Modeling (ISM) to the field of website selection.

One common method to select input ground motions to predict dynamic behavior of structures subjected to seismic excitation requires spectral acceleration (S_a) match target mean response spectrum. However, dispersion of ground motions, which explicitly affects the structural response, is rarely discussed in this method. Generally, selecting ground motions matching target mean and variance has been utilized as an appropriate method to predict reliable seismic response. The goal of this paper is to investigate the impact of target spectra variance of ground motions on structural seismic response. Two sets of ground motions with different target variances (zero variance and minimum variance larger than inherent variance of the target spectrum) are selected as input to two different structures. Structural responses at different heights are compared, in terms of peak, mean and dispersion. Results show that increase of target spectra variance tends to increase peak floor acceleration, peak deformation and dispersions of response of interest remarkably. To short-period structures, dispersion increase ratios of seismic response are close to that of S_a of input ground motions at the first period. To long-period structures, dispersions of floor acceleration and floor response spectra increase more significantly at the bottom, while dispersion increase ratios of IDR and deformation are close to that of S_a of input ground motions at the first period. This study could further provide useful information on selecting appropriate ground motion to predict seismic behavior of different types of structures.

This study was undertaken to provide useful information to restaurant managers by analyzing eating out behavior and the diverse needs and wants of the people residing in the Seoul area. four hundred twenty-seven(427) people were sampled for this study and classified into three groups : housewives, salarymen and college students. The results of this study are as follows : (10 Among the groups, there were significant differences in general eating out behavior such as 'frequency' 'preferred food style' and 'who pays the check' among others. (2) The study showed housewives listing 'special occasion' as 'taking care of meal' (3) All groups considered 'price' as especially important. (4) When selecting a menu item, taste was considered most important by all groups. Housewives showed nutritional value to be important while salarymen chose the same item as companions an college students showed 'portions' and 'price' to be important. (5) degree of satisfaction of restaurants were found to be low with items such as ' price'. 'range of menu choices' and 'courteousness of employees' being relatively low.

This study was conducted to investigate the effects of weaning behavior on infants' health status. 294 mothers who had infants, aged 4 to 12 months in Seoul, were selected by cluster sampling and answered by the special questionnaires. Result were as follows : 55.1% of mothers had commenced weaning by 3 months of age. Infants eatten commercial weaning food except for infant eatten only home made weaning food were 88.8%. The case that mothers couldn't make weaning food at the home were 56.6% because they didn't know how to cook of weaning food. Cereals were used frequently as infant foods while meat and fish were lesser used. The higher mother's education level had, the higher nutritional knowledge had. Nutritional knowledge was not influenced on selecting the kinds of weaning food. But the higher nutritional knowledge had, the more desirable weaning behavior mother tended to be had. The more desirable weaning behavior mother had, the more infant's health status tended to be improved. Therefore, for the desirable weaning behaviors of mothers and the improvement of infants' health status, nutritional education program including cook method and development of infant food is need.

The purpose of this study was to develop a housing choice behavior program to cultivate housing value orientation among middle-school students. The importance of cultivating housing value orientation in middle school was examined by investigating the relationship between housing value orientation and housing choice behavior, following which a program was developed to cultivate housing value orientation based on various housing values. Housing choice behavior was defined as selecting the ownership type, housing type, housing size, and neighborhood environment of housing, and the program was developed in 12 sessions to understand housing values and cultivate housing value orientation through learning housing choice behavior. The features of this program were as follows. First, although housing choice behavior is not covered in middle-school home economics, the 2015 revised national curriculum and current middle-school textbooks were analyzed and developed in consideration of the level available in schools. Second, it was possible to develop a housing value orientation that encompasses various housing values, including activities used to consider such values as the basis for housing choice behavior by each sessions. Third, the program was meaningful in that it developed practical problem-solving and living independence skills through learning activities, including available sites, experience cases, and housing welfare that cannot be experienced directly or indirectly.

Purpose: The role of salespersons' emotions in effective selling behavior garners attention among scholars and practitioners. Previous studies have investigated the effects of emotional intelligence and emotional labor on sales success separately. However, to understand the whole process, the relationships among salespersons' cognition, emotions, and behaviors should be considered simultaneously. Accordingly, we uniquely examined how salespersons' emotional intelligence (emotional antecedent) and customer orientation (cognitive antecedent) influence their emotional labor (deep acting vs. surface acting), adaptive selling behavior, and the selling results in the retail environment. Research design, data, and methodology: To improve methodological rigor, we used the dyadic approach. We measured 182 salespersons' emotional intelligence, customer orientation, and emotional labor, and 364 customers assessed the salespersons' adaptive selling behavior and selling results in the insurance and duty-free department retailing sectors. Result: The findings suggest that salespersons' customer orientation and emotional intelligence relate to deep-acting of emotional labor, affecting their adaptive selling behavior and relationship quality with customers. Conclusions: As for managerial implications, sales managers may well consider emotional intelligence levels when selecting salespersons in the retail industry. Additionally, practical training programs are required to cultivate customer orientation, emotional intelligence, and deep acting while performing emotional labor.
