The rheological properties of Korean white gruel at various concentrations (4-7%) and temperatures (30-60$^{\circ}C$) were investigated. The rheological behavior of Korean white gruel was evaluated by Herschel-Bulkley equation and showed typical Bingham psedoplastic behavior with yield stress. Flow behavior index was increased at over 5％ of rice content. Consistency index was increased by the increase of concentration of rice. But, measuring temperature was not effected in the flow behavior index and consistency index. Yield stress was increased by the incerase of concentration of rice and the decrease of measuring temperature. The activation energy of flow of Korean gruel increased from 7.646 to 32.949${\times}$10/Sup 6/ J/Kg$.$ mole by increasing concentration from 4％ to 7％. As the temperature increased from 30$^{\circ}C$ to 60$^{\circ}C$, B-value decresed from 1.214 to 0.947 Flow behavior index and consistency index was reduced during storage.

As customers' participation in B2C e-commerce increases, customers are getting more involved in the delivery of services, which may even go beyond the completion of service transactions. To examine such proactive extra-role online customer behavior, we delve into organizational citizenship behavior framework, which has been recently extended to examine customer citizenship behavior (CCB) in the service market area. Although CCB is vital for online retailing success, MIS and e-commerce research efforts have generally focused on the customer's customer coproduction that are customer in-role behaviors. Moreover, although the effect of information created by anonymous strangers on other customers increase, interpersonal trust research have focused on only the relationship between a seller and a customer. Therefore, this study attempts to answer two research questions: What are motivational factors that affect CCB? How differently do the two kinds of interpersonal trusts (trust in online retailer and trust in customers) influence customers?

Study on users which was done centering information approach, acquisition and interoperability between users and information systems need to be studied in the perspective of information behavior including information acquisition and sharing behavior in the changing information environment. In order to analyze users' information acquisition and sharing behavior's demands, motives and processes in libraries and internet environments, integrated approach of both qualitative and quantitative study were tried by applying Wilson's information behavior concept. Plans for the improvement of information services were suggested on the basis of integrative analysis.

This study explored the antecedent variables associated with variability in toddler's aggressive behavior. The subjects were 182 toddlers(101 boys and 81 girls) and their mothers. Data were collected via questionnaires. The main results of this study were as follows ; First, aggression was significantly correlated with toddler age, but not with gender. Mother's parenting was related to boy's aggression, whereas both temperament and parenting were significantly related to girls' aggressive behavior. However, day-care variabes were not the significantly associated with toddler's aggression. Second, regression analyses revealed the interaction effect of child temperament and parenting, after controlling for main effects.

The purpose of this article is to examine the relationship between unsafe behavior, human factor and human error. For the object, several correlation analyses for those three elements were implemented. Several hypotheses for the relationship between them was suggested. The suggested hypotheses were verified by a comprehensive survey received from 132 safety manager of manufacturing industry. The conclusions were proven from the hypotheses verificaiton as belows; 1) The dependent relation items between unsafe behavior and human factor are dress protection tool, machine(equipment) and working rule have a dependent relation. 2) The dependent relation items between human factor and human error are uncommunication, control, slaps, fatigue, education, system, unmonitoring, failure. 3) The dependent relation items between human error and unsfafe behavior are decline and product/working method,failure and uncommunication have a dependent relation.

To promote the efficiency of university library information service, the analysis of information-seeking behavior of information service users must be pre-examined. Under such assumption, this study made a survey of the information-seeking behavior of university faculty and students of five National Universities and the Universities of Education. This research found out the difference of behavior among main users when they sought the information, which was supplied by university libraries, and gave suggestion and advice for the improvement of the university library information service.

This paper first introduces the U. S. pension system and its current trends. Then the following two sections discuss the research on worker behavior of defined contribution plans, a popular pension plan available for American workers in recent years, and the adequacy of retirement income among American people. The last section is a summary. This paper reviews the trend of the U. S. pension system, research on worker's behavior of defined contribution retirement plans, and studies on retirement income adequacy. These themes may have common or different features in other countries, such as Korea. This paper provides helpful information for private and public policy makers and researchers of these topics in Korea to advance their understanding of pension and retirement behavior and facilitate effective policy making of pensions and retirement.

The Manchester Driver Behavior Questionnaire (DBQ) is the most commonly used frameworks for investigating the relationship between self-reported driving behavior and accident involvement. After Reason et al. introduced DBQ, there were many studies replicating the research of Reason et al. in many countries. There was, however, no study replication of the Reason's research in Korea. The aim of this study is to replicate the distinction among errors, lapses and violations, and to evaluate the relationship of these behaviors with road traffic accidents on Korean drivers. 223 Korean drivers completed the Korean version of original DBQ with questions regarding background information, such as age, gender, annual mileage and accident involvement. Participants answered self-assessment questions, also. Factor analysis revealed three factors like Reason et al. The three factors were dangerous errors, violations and relatively harmless errors.

The present paper discusses the behavior of the reinforced concrete beams subjected to torsion by applying the endochronic plastic model in conjunction with the softened truss model. The endochronic constitutive equations are developed to describe the behavior of concrete. The mechanical behavior of concrete is decomposed into hydrostatic part and deviatoric part. New definition of the bulk modulus and the shear modulus are defined in terms of compressive strength of concrete. Also, new deviatoric hardening function is developed. Then, the endochronic constitutive equations of concrete are applied with the softened truss model for the behavior of the reinforced concrete beams subjected to torsion. The theoretical results obtained based on the present model are compared with the experimental data. The present model has shown the ability to describe the behavior of reinforced concrete beams subjected to torsion.

The purpose of this study is to review the effects of organizational citizenship behavior on innovative behavior and intention to leave, and the moderating effects of self-efficacy in Korea Politechnics' teachers and professors. In order to verify and achieve the purposes mentioned above, questionnaire data were gathered and analysed from 206 employees of Korea Politechnics campus. Empirical survey's findings are as follows; First, altruism, conscientiousness, sportsmanship appeared to be positively related with innovative behavior. Second, courtesy, conscientiousness, sportsmanship appeared to be negatively related with intention to leave. Third, self-efficacy moderated negatively the relationship between altruism and intention to leave. Fourth, self-efficacy moderated negatively the relationship between sportsmanship and intention to leave.
