This study was conducted to investigate the change in activity and mounting behavior in Hanwoo (Korean Native Cattle) during the peri-estrus period and its application to estrus detection. A total of 20 Hanwoo cows were fitted with a neck-collar accelerometer device, which measured the location and acceleration of cow movements and recorded the number of instances of mounting behavior by the altitude data. The data were analyzed in three periods (24-, 6-, and 2-h periods). Blood samples were collected for 5 days after the prostaglandin F2α (PGF2α) injection, and the concentrations of estradiol, progesterone, follicle-stimulating hormone, and luteinizing hormone were determined by enzyme-linked immunosorbent assays. Activity and mounting behavior recorded over 2-h periods significantly increased as estrus approached and were more efficient at detecting estrus than over 24- and 6-h periods (p < 0.05). Endocrine patterns did not differ with the variation of individual cows during the peri-estrus period (p > 0.05). Activity was selected as the best predictor through stepwise discriminant analysis. However, activity alone is not enough to detect estrus. We suggest that a combination of activity and mounting behavior may improve estrus detection efficiency in Hanwoo. Further research is necessary to validate the findings on a larger sample size.

The purpose of this study is to examine the effects of the transformational leadership on helping behaviors and deviant behaviors of organizational members and to verify the control effect of value consistency and to suggest a process for effective business management and human resource management. For this purpose, questionnaires were distributed to employees working in office management, area marketing, and manufacturing industries in Seoul, Gyeonggi and Chungcheong provinces, and the final 334 copies were used for empirical analysis. Data were analyzed using SPSS 18.0, and reliability analysis, factor analysis for validity, correlation analysis, and regression analysis were conducted to verify the research hypothesis. The results of the empirical analysis based on the questionnaire based on the object are as follows. First, charisma of transformational leadership showed negative impact on helping behavior, and intellectual stimulation of transformational leadership and individual care showed positive influence on helping behavior. Second, charisma of transformational leadership showed negative influence on deviant behavior, whereas intellectual stimulation of transformational leadership and sub - constitutional factor of individual care did not show significant influence on deviant behavior. Third, as a result of confirming the moderating role of transformational leadership and helping behavior on the level of value consistency, it showed moderating effects on charisma and individual consideration of transformational leadership. Through this study, we proved the effectiveness of transformative leadership which increases the helping behaviors of the members and reduces the deviant behavior. Based on this, we proposed the necessity of developing managers' transformational leadership improvement program to enhance the sustainability of the organization. And we confirmed the partial influence relationship on the adjustment effect of value consistency. In addition, negative influence of charisma suggests a significant point in the management process design.

Previous studies on information systems (IS) and finance suggest that information on stock message boards influence the investment decisions of individual investors. However, how information on online stock message boards influences an individual investor's buy or sell decisions is unclear. To address this research question, we investigate the relationship between a number of posts on stock message boards and order imbalance in stock markets. Order imbalance is defined as the difference between the daily sum of buy-side shares traded and the daily sum of sell-side shares traded. Therefore, order imbalance can suggest the direction of trades and the strength of the direction with trading volumes. In this regard, this study examines how the number of posts (information on stock message boards) influences order imbalance (stock trading behavior). We collected about 46,077 messages of 40 companies on the Korea Composite Stock Price Index from Paxnet, the most popular Korean online stock message board. The messages we collected were divided based on in-trading and after-trading hours to examine the relationship between the numbers of posts and trading volumes. We also collected order imbalance data on individual investors. We then integrated the balanced panel data sets and analyzed them through vector regression. We found that the number of posts on online stock message boards is positively related to prior order imbalance. We believe that our findings contribute to knowledge in IS and finance. Furthermore, this study suggests that investors should carefully monitor information on stock message boards to understand stock market sentiments.

It is necessary to understand the relationship between socio-cultural elements and smoking, alcohol, and marijuana use behaviors in order to plan public health policy or health promotion program of Mexican Americans. Demographic, socioeconomic status, and acculturation are variables which reflect mechanisms socialization influences these behavior patterns among this population. Thus, this study investigates the prevalence of addictive behaviors and individual differences on addictive behaviors related to variables of acculturation, age, gender, education, and income. And the interrelations among addictive behaviors are also examined. The analyses used data for Mexican Americans from the U.S. Hispanic Health and Nutrition Examination Survey conducted from July 1982 through December 1984 by the National Center for Health Statistics. ANOVA and correlation coefficients were used for this study. This study found that there are gender differences among addictive behaviors in their prevalence. Both males' and females' alcohol and marijuana use behaviors are positively related to the acculturation. Females' smoking behavior is positively related to acculturation while males' smoking is negatively related to it. Income and education are negatively related to males' smoking and positively related to males' alcohol behavior. However, males' marijuana behavior is not related to income. Females' smoking behaviors is not significantly related income and education. Education and income are positively related to marijuana behavior among females.

The purpose of this study is to examine the information search behavior of medical consumers visiting a hospital, and investigate the consumption values of medical consumers, classified according to the information search behavior, and characteristics of online health and disease information. This study also tried to identify the factors affecting medical consumers classified according to information search behavior, and gain an extensive understanding of medical consumers'consumption values and online information use. The analysis results of this study are as follows: First, the consumption values of medical consumers were classified into a total of 7 factors, i.e. future-positive value, family-oriented value, sustainablehealth value, rational-progressive value, social-cooperative value, socialachiever value and hedonistic-individual value. Next, the characteristics of medical consumers'online information search behavior were classified into three types of consumer groups, i.e. the limited information-oriented consumer group, the practical information-oriented consumer group and the passionate information-oriented consumer group. Second, the analysis of the differences among the three groups classified according to the characteristics of the information search behavior in terms of consumption values, use of online information sources, utility and the intention to reuse online information showed that all the differences were statistically significant. The passionate information-oriented consumer group showed the highest scores in the sustainable-health value, the social-achiever value and the hedonisticindividual value. Third, the factors affecting medical consumers, classified into three groups according to the characteristics of the information search behavior, were found to be socio-demographic variables like consumers' age and occupation, consumers'consumption values, use of online information sources, and utility of online information. This study tried to understand what values medical consumers have according to the differences in the information search behavior by examining the consumption values of medical consumers according to the information search behavior. The significance of this study lies in the fact that consumption values are instrumental in understanding medical consumers by identifying the fundamental motives and desires of consumers' behavior.

This practice parameter for non-pharmacological treatment for attention-deficit hyperactivity disorder (ADHD) review the domestic and international literature on the psychosocial treatment of children and adolescents with ADHD. This parameter include the parental training & education, cognitive behavior therapy(group or individual), social skill training, family therapy, play therapy (individual psychotherapy) and non-traditional therapy (art therapy, herbal therapy et al). Among them, there is some proven evidence only in parental training & education and cognitive behavior therapy. So, this parameter describes some details only in the field of parental training & education and cognitive behavior therapy. The efficacy or effectiveness, especially, cost-effectiveness of specific psychosocial treatment method for ADHD cannot be fairly assessed due to the scarcity of controlled clinical data. Based on the clinical expert consensus and limited evidence, we cautiously suggest the practice recommendations about the non-pharmacological psychosocial treatment fur children and adolescents with ADHD.

Objectives : The purpose of this study which adopted a qualitative method was to evaluate blood pressure management behaviors of pre- and stage 1 hypertension patients and to provide fundamental data for developing a strategy about proper oriental medical treatment through analyzing factors related to a moxibustion clinical trial. Methods : Semi-structured interviews that focused on personal experiences with hypertension and its management were conducted with 10 hypertensive patients. The interviews lasted for approximately 50 minutes. Results : Most participants recognized that the direct cause of high blood pressure was unhealthy behavior rather than inheritance. Thus, the hypertensive patient believed they could recover their blood pressure to a normal level through removing the direct cause of hypertension instead of taking drugs. The reasons for these statements were that the drugs for controlling hypertension are not natural and they may have side effects. On future management plan of patients, most of them will continue to keep moxibustion and healthy behavior in the well-controlled blood pressure group. However in the uncontrolled blood pressure group, there was an increasing tendency to begin medication. Conclusions : For developing a strategy for an individual approach to hypertension management, we need to develop a client-centered attitude and strategy. That is, we need to tailor our approach to individual cases to avoid generalizations and stereotyping when developing an adherence increasing strategy.
