The purpose of this study was to examine the relationship between parental attribution and self-perception in parenting roles according to parenting success or failure situations. A total of 138 mothers who have toddlers in Seoul and other big cities in Korea completed questionnaires, and data were analyzed by paired t-test, Pearson's correlation coefficient, Fisher's Z score, and multi-regression. The results are as follows: First, mothers in parenting success situations showed higher parental attribution than mothers in parenting failure situations. Second, correlations between parental attribution and self-perception in parenting roles turned out to be significantly different between parenting success situations and failure situations. Third, both internal attribution such as ability and effort, and external attribution such as child behavior and task difficulty, significantly predicted self-perception in parenting roles including equilibrium feeling, competence, satisfaction and parenting investment, especially in parenting failure situations. The implications of the difference in parental attribution between parenting success and failure situations have been discussed.

The puprpose of this study were to investigate the conceptual framework of situational variables on clothing types, to find out the relationship between situational variables and personality characteristics, and to determine the effects of situational variables on clothing purchase types. A Questionnaire was developed based on the previous studies. Data was collected from 530 women living Pusan and analyzed by the factor analysis, person correlation, and discriminant analysis. The results of this study were as following; Communication situations and purchasing situations were found out to be different on clothing purchase types. In planning purchase, consumers were affected by printed and tele-communication information search and were affected by interpersonal information search in unplanning purchase. In impulseing purchase, consumers were affected by store information search. It was found out that consumers with high rational clothing involvements were affected by only the purchasing situations when they would buy clothing, but consumers with high emotional clothing involvements were affected by the communication situations as well as the purchase situations. Consumers with high self monitoring traits were not affected by the communication situations and mostly the purchasing situations. Results showed that the purchasing situation was the most significant variables in clothing purchase behavior, communication situating or purchasing situations were differently influenced on clothing purchase types.

Recently, with the development of IoT, AI, and mobile terminals, medical information platforms are expanding. The medical information platform can determine a patient's emergency situation, and medical staff can easily access patient information through a mobile terminal. However, in the existing platform, emergency situation decision is delayed, and faster and stronger authentication is required in emergency situations. Therefore, we propose an edge computing-based medical information platform for automatic authentication using patient situations. We design an edge computing-based medical information platform architecture capable of rapid transmission of biometric data of IoT and quick emergency situation decision, and implement the platform data flow in emergency situations. Relying on this platform, we propose the automatic authentication using patient situations. The automatic authentication protects patient information through patient-centered authentication by using the patient's situation as an authentication factor, and enables quick authentication by automatically proceeding with mobile terminal authentication after user authentication in emergencies without user intervention. We compared the proposed platform with existing platforms to show that it can make quick and stable emergency decisions. In addition, comparing the automatic authentication with existing authentication showed that it is fast and protects medical information centered on patient situations in emergency situations.

The duel is an extreme case of game situations. The duel is of zero-sum type, but a infinite game. This duel situation appears not only in extreme competitive situations such as war, but also in economic situations such as bidding. The study on duel situations started from late 1940's, but considerable contributions have been made in 1960's by Ancker, Restrepo, Yanovskaya, Kimeldorf among others. Specially Kimeldorf recently has made big contribution in developing the theory of the game-theoretic duel. The purpose of this paper is to summarize and systemize the theory of the game-theoretic duel. In the first part, noisy duel situations shall be dealt with, and in the second part, silent duel shall follow. Finally these two situations shall be generalized in the form of continuous firing model.

A simulated realistic virtual environment is inhabited by autonomous cyber-humans who play the roles of agents in events. A key element, which enables this realism, is the historical context formed by time and space. A knowledge-representation scheme, composed of both spatial and temporal aspects needed by the agent to respond to dynamically changing situations, is essential for the design of a realistic virtual agent. In this work, spatial and temporal aspects of dynamic situations in the virtual environment have been formalized as a key component of our knowledge-representation scheme. This scheme provides a mathematical framework to construct realistic virtual situations that change with time, and background knowledge for agents in the simulated environment to deduce new pieces of information and plan against changing situations.

Gender role flexibility in social and non-social situations across 4 areas of gender-role concepts(appearance, activities, occupations, and personality traits) were studied in 74 1st, 3rd, and 5th grade children. They were interviewed with 16 pictures depicting cross-gender characteristics. Children showed higher flexibility in social than in non-social situations. In social situations, children justified cross-gender characteristics in all 4 areas of gender-role concept. In non-social situations, children showed (a) highest flexibility in occupations and lowest in appearance, (b) lower flexibility toward male than female target children, (c) peak flexibility at age 8, then remaining the same except for appearance, and (d) higher flexibility in girls than in boys. In social and non-social situations children gave variable justifications for flexibility.

Previous researches on risk attitudes or on the typical utility functions have mostly focused on how the risk attitude of decision maker varies when changes are made in one or two lottery reference points such as consequence domain and magnitude of probability under assumed risk situations represented by simple lotteries. It is, however, very difficult to forecast dominant risk attitudes under risk situations which exhibit a complex combination of many reference points. In this study, twelve risk situations which a decision maker may confront in real decision-making situations were formulated by combining in various ways three reference points, that is, magnitude of probability, consequence domain, and magnitude of gain or loss. Then through a questionnaire dominant risk attitudes under every assumed risk situation were investigated, and the general shape of utility function implied by the experimental results were derived. Results of the present study show that none of the three reference points have dominant effect over the others due to complicated interaction between them, and given the twelve risk situations the observed risk attitude widely varies from strong risk taking to strong risk aversion.

This study analyzed the socio-psychological process of adolescent drinking behaviors. A total 1,732 high school students in Pusan city were studied by the questionnaire from May to July, 1985. A structural model based on review of the literature was examined in order to test the following three hypotheses: (1) sociocultural and environmental impact on the adolescent belief system for drinking, on drinking situations, and on experiences of deviation, (2) relationships among adolescent belief system, drinking situations, and experiences of deviation, and (3) impact of antecedent variables on adolescent drinking levels. All hypotheses were supported by the data. The important outcomes were discussed as follows: 1. Because interpersonal factors were influential for the adolescent belief system concerning drinking, public drinking education through mass communication or drinking education in the curriculum were recommended. In addition to sex variables, friends' drinking and sibling's drinking were shown to have a positive impacts on drinking situations. Also, adolescent self-reported parents' views on drinking had significant effects. Because adolescent deviant experiences were generally affected by environmental factors, it is recommended that positive extra-curricular activities at both home and school should be investigated. 2. There were significant relationships among adolescent belief systems, drinking situations, and deviant experiences. However, adolescent drinking behaviors in supervised situations had weak correlations with their belif systems and deviant behaviors. 3. Adolescent drinking levels were remarkably influenced by drinking behaviors in unsupervised situations. Because it is difficult to control actual adolescent drinking behaviors in unsupervised situations, it is important to fortify their belief system with continuous education programs.

Recently, with the development of smart technology, in medical information platform, patient's biometric data is measured in real time and accumulated into database, and it is possible to determine the patient's emergency situations. Medical staff can easily access patient information after simple authentication using a mobile terminal. However, in accessing medical information using the mobile terminal, it is necessary to study authentication in consideration of the patient situations and mobile terminal. In this paper, we studied on medical information platforms based on big data processing and edge computing for supporting automatic authentication in emergency situations. The automatic authentication system that we had studied is an authentication system that simultaneously performs user authentication and mobile terminal authentication in emergency situations, and grants upper-level access rights to certified medical staff and mobile terminal. Big data processing and analysis techniques were applied to the proposed platform in order to determine emergency situations in consideration of patient conditions such as high blood pressure and diabetes. To quickly determine the patient's emergency situations, edge computing was placed in front of the medical information server so that the edge computing determine patient's situations instead of the medical information server. The medical information server derived emergency situation decision values using the input patient's information and accumulated biometric data, and transmit them to the edge computing to determine patient-customized emergency situation. In conclusion, the proposed medical information platform considers the patient's conditions and determine quick emergency situations through big data processing and edge computing, and enables rapid authentication in emergency situations through automatic authentication, and protects patient's information by granting access rights according to the patient situations and the role of the medical staff.

Objective: This study developed a hierarchy of conditions of applications(devices), situations and functions which are applicable to gesture interface. Background: Gesture interface is one of the promising interfaces for our natural and intuitive interaction with intelligent machines and environments. Although there were many studies related to developing new gesture-based devices and gesture interfaces, it was little known which applications, situations and functions are applicable to gesture interface. Method: This study searched about 120 papers relevant to designing and applying gesture interfaces and vocabulary to find the gesture applicable conditions of applications, situations and functions. The conditions which were extracted from 16 closely-related papers were rearranged, and a hierarchy of them was developed to evaluate the applicability of applications, situations and functions to gesture interface. Results: This study summarized 10, 10 and 6 conditions of applications, situations and functions, respectively. In addition, the gesture applicable condition hierarchy of applications, situation and functions were developed based on the semantic similarity, ordering and serial or parallel relationship among them. Conclusion: This study collected gesture applicable conditions of application, situation and functions, and a hierarchy of them was developed to evaluate the applicability of gesture interface. Application: The gesture applicable conditions and hierarchy can be used in developing a framework and detailed criteria to evaluate applicability of applications situations and functions. Moreover, it can enable for designers of gesture interface and vocabulary to determine applications, situations and functions which are applicable to gesture interface.
