This study aimed to examine relationships between founders' entrepreneurial leadership, team learning behavior, team boundary spanning, and perceived performance in early-stage startups. The following results were recorded: (i) the indirect effects of entrepreneurial leadership on perceived performance via team learning behavior were statistically significant (β=.309, p<.05). (ii) relationships between team learning behavior and perceived performance were strengthened by team boundary spanning behavior (β=.259, p<.05). In this study, three practical implications are provided as follows: (i) startups need to seek team learning readiness and external learning stimulus to facilitate generative and transformative team learning; (ii) accelerators need to develop an entrepreneurial leadership program for founders; and (iii) startups need to explore external information by interacting with investors, R&D institutions, and other startups to strengthen the impact of team learning behavior on performance. Furthermore, two directions for future research are suggested as follows: (i) future researchers need to test causal relationships between entrepreneurial leadership and team learning behavior based on a newly designed time-series measurement plan; (ii) the actual effects of entrepreneurial leadership, team learning behavior and team boundary spanning on financial performance need to be tested two or three years later when the financial performance of early-stage startups usually becomes evident.

Purpose: This study aimed to develop a scale to measure variables related to alcohol drinking prevention behavior in early elementary school, based on the theory of planned behavior. Methods: A scale was developed to measure variables related to alcohol drinking prevention behavior. Initial items for direct evaluation were constructed through a literature review, and those for belief-based indirect measure were generated through interviews with 30 second- and third-grade elementary school students. The collected data from 286 third-grade elementary school students were then subjected to item analysis, exploratory and confirmative factor analysis, criterion-related validity testing, and internal consistency assessment. Results: The final scale consisted of 35 items. Intention, attitudes, subjective norms, and perceived behavioral control explained 82.7% of the variance; behavioral beliefs, normative beliefs, and control beliefs explained 65.6% of the variance; and evaluation of outcome, motivation to comply, and power of control beliefs explained 72.8% of the variance. The confirmatory factor analysis indicated that the theoretical models had a satisfactory goodness of fit. Criterion-related validity was confirmed between the direct evaluation variables and the indirect measure variables (attitudes r=.64, p<.001; subjective norms r=.39, p<.001; perceived behavioral control r=.62, p<.001). Cronbach's α was .89 for the direct evaluation variables and .93 for the indirect measure variables. Conclusion: The scale developed in this study is valid and reliable. It could be used to measure and explain variables related to alcohol drinking prevention behavior in early elementary school.

Purpose : The purpose of this study was to explore the subjective experiences of problem drinkers participating in the early intervention program for moderate alcohol drinking. Methods : A qualitative descriptive study design was used. Data were collected through individual interviews with thirteen problem drinkers and analyzed using qualitative content analysis. Results : The experiences of the problem drinkers participating in the early intervention program were derived from four themes and nine sub-themes in terms of awareness, alcohol expectancies, perceived self-efficacy and behavioral change. They participated in programs offered in the workplace, and there were differences in motivation level among individuals, but generally accepted the necessity of the program. Participants who had trust with the program provider were more likely to change drinking behavior. Conclusion : Problem drinkers who participated in the early intervention program showed that it is a useful approach to change the problem drinking behavior by promoting awareness of alcohol-related knowledge, motivation for change through acquiring enough information and acquisition of self-efficacy as a behavior skill. These findings can be used as basic information for implementing and adapting early intervention for prevention of alcoholism in primary health care setting including workplace.

The present study investigated the effects of individual, family, school, and community factors on the onset of adolescent runaway behavior. Using the Korean Youth Panel data(n=3,118), discrete-time survival analysis was applied for research purposes. Results showed that the likelihood of onset of adolescent runaway behavior increased sharply during the early middle school years. The variables of self-control, aggression, parents' divorce, paternal abuse, attachment with parents, and number of delinquent peers were associated with the likelihood of runaway behavior. These results suggest that special attention should be paid to adolescents in the early middle school years and that various preventive programs, e.g., aggression and stress management, and peer relations programs, should be developed and implemented.

Research with parents of children with Asperger Syndrome was conducted to assess whether the level of positive parental attachment correlated positively with positive parenting behaviors and negatively with negative parenting behaviors. Participants were recruited from internet. The Parental Bonding Inventory measured parents' perception of their bonding or attachment with three aspects of their own parents: warmth, control, and care. In the Parenting Behavior Inventory, parents reported recent interaction/reaction behaviors with their child, and results focused on two aspects of parenting, supportive/engaged and hostile/coercive behaviors: each identified as problematic to parenting and attributable to a variety of specific parenting behaviors. Analysis of demographic variables for correlations with positive parenting behaviors and negative parenting behaviors were carried out by Pearson correlations. Two separate standard multiple regressions, one for positive parenting behaviors and one for negative parenting behaviors, were conducted. Findings support the hypothesis that positive early attachment experience of parents has a significant impact upon their own positive parenting skills with their child with Asperger Syndrome. However, multiple regression of negative parenting behavior found no significant negative contribution by parental attachment. Demographic variables proved to be important.

The purpose of this study was to examine the effects of teachers' responsiveness on teachers' strategies of problem behavior guidance. Teachers' responsiveness variables consisted of acceptance, sensitivity, consistency, warmth and teachers' strategies of problem behavior guidance variables consisted of positive proactive strategies, positive reactive strategies, negative reactive strategies. Subjects were 151 early childhood teachers in Seoul and Chungcheungnam-do. The collected data were analyzed using simple regression and hierarchical multiple regression. The main results of this study were as follows. Teachers' acceptance, sensitivity, consistency, warmth were positively related to teachers' positive proactive strategies and positive reactive strategies of problem behavior guidance. On the other hand, teachers' warmth was negatively related to teachers' negative reactive strategies. As results of examining relative effects of teachers' responsiveness on positive proactive strategies of problem behavior guidance, the influential variables were warmth and acceptance. The relative effects of teachers'responsiveness on positive reactive strategies of problem behavior guidance, the influential variables were sensitivity and acceptance. The relative effects of teachers' responsiveness on negative reactive strategies of problem behavior guidance, the only influential variable was warmth.

Recently, the serviceability and durability of concrete structures under thermal load have received great attention. The thermal stress and clacking behavior of concrete at early ages are one of the important factors that affect such serviceability and durability of concrete structures. Nevertheless, most studies on the behavior of early-age concrete have been confined to the temperature and strain development itself in the laboratory. The desirable efforts to explore the material properties of concrete at early-ages have not been made extensively so far. The purpose of the present study is, therefore, to identify some important material properties that affect the stress behavior of concrete at early-ages. To this end, full-scale concrete base-restrained wall members have been fabricated, and many sensors including thermocouples, strain meters and stress meters were installed inside of the wall members. These sensors were to measure the development of temperatures, strains and stresses at several location in concrete walls during the hardening and curing phase of early-age concrete. By using these measured values of strain and stress, the compliance function at early-age was identified. The basic form of compliance function derived in this study follows the double-power law. However, the results of present study indicate that the values of existing compliance functions are much lower than actual values, especially at very early-ages. It can be seen that the prediction of stresses of early-age concrete based on the proposed compliance function agrees very well with test data. The present study allows more realistic evaluation of varying stresses in early-age concrete under thermal load.

The deformations of concrete specimens were measured at early at early ages, in order to verify the applicability of FBG(Fiber Bragg Grating) sensors. The FBG sensors were directly buried at various locations in the beam-type RC specimens at the time of fabrication. In this experiment, the changes of strains in concrete at early age were successfully measured as the movement in wavelength of light signals. The FBG sensors may be a very effective tool to investigate the mechanical/thermal behavior inside of concrete structures.

The purpose of this study was to investigate the relationship between body cathexis and five aspects of clothing behavior. Body cathexis was measured by Secord and Jourard's Body Cathexis Scale, fit in clothing was measured by Mclean's questionnaire, and three aspects of clothing were assessed with Lee, Lim, Lee, and Kahng questionnaire dealing with clothing satisfaction, status symbol, and fashion interest. Preference for fashion style was determined by line drawings of clothing designs representing current fashion and non-current fashign. The questionnaires were administered to a sample of middle-aged women (40$\~$64 year of age) in Seoul. The data for 351 respondents were analyzed by correlation and t-test. The results were : 1) Body cathexis was positvely related to clothing satisfaction for early middle-aged women as well as advanced middle-aged women. 2) Body cathexis was positively related to fit in clothing for early middle-aged women as well as advanced middle-aged women. 3) Fashion interest was positively related to preference for fashion style in early middle-aged women, 4) Scores of early middle-aged women on body cathexis, fit in clothing and preference for fashion style were significantly higher than those of advanced middle-aged women, that is, early middle-aged women had a higher self-satisfaction with body cathexis and fit in clothing. They also preferred modern fashions in contrast to be advanced middle-aged sample.
