As smartphone use is increasing within the middle-aged population, society should pay closer attention to the mental health problems associated with smartphone addiction. This study examines the possibility that depression, anxiety, and ADHD can be interpreted not only as negative aspects, but also as positive aspects, in an addiction-related individual. We used habitual and addictive smartphone behavior as the dependent variables; anxiety, ADHD, depression, and habitual smartphone use as the independent variables; and self-control as a moderating variable. Depression and ADHD in smartphone users were found to be associated with higher levels of addictive smartphone use. Anxiety was having negative effect on addictive smartphone use. However, habitual smartphone use didn't significantly affect addictive smartphone use. Further analysis indicated that depression, anxiety, and ADHD have mediating effects on habitual smartphone use. This study confirmed that psychological factors in adults, as well as habitual/addictive smartphone use and self-control, significantly influence smartphone overdependence.

In this paper, the design of explicit rate-based congestion control in high speed communication networks is considered. The goal of congestion control is to achieve high link utilization, low packet loss, low delay, and fairness among the best-effort sources. To deal with the propagation delays associated with the best effort sources, An MPC technique is employed to solve the congestion problem[1] here. However, the problem with this method is that the closed loop performance relies highly on the knowledge of average service rate. This paper focuses on coping with the problem described above by using a CARIMA model for service rate(available rate).

Virtual community is a social aggregation to attain some goals in an IT-supported virtual space (Lee et al., 2002). As lots of virtual communities generate robust and reliable outputs with low control and low incentive, previous researchers was interested in the questions, "why do they participate?" or "how are they controlled?". But. as Katz (1964) said, the most important part of the high-performing organization is the behaviors of members in the organization. Therefore, this research is to examine the relationship between the performance and the behaviors of participants in the virtual community. First, we propose 6 types of behaviors related to high performance in the virtual community: 'Continuous Attendance', 'Complying with the organizational value, policies, and regulations', 'Protection', 'Suggestion for the improving', 'Self-training', and 'Favorable behavior'. The six types of behaviors are extracted from the framework of Katz (1964) and Brief and Motowidlo (1986). The reason why each behavior is positively related with high-performance is that those who continuously attend have more responsibility than temporary participants do; complying with the rules of a virtual community means that they may make more reliable outcome; 'Protection' is one of the prosocial-behaviors and those who protect the community may concern the benefit of the virtual community when they participate: those who suggest some ideas for improvement may contribute to the virtual community; 'Self-training' behavior means that participants really want to have high quality in their contribution: those who have 'Favorable attitude' consider other members in the virtual community when they participate. Then, we perform an empirical analysis with the survey from participants in the Knowledge service of Naver.com, to show those behaviors are associated with the high-performance. To make the measurement for the six behaviors, we use CVR (content validity ratio) method (Lawshe, 1975), interviewing 12 experts. The dependent variable, performance of participation, is measured by 'ratio of selected answer' given by the Naver.com. We use email survey. We sent 1200 emails to randomly selected participants in the knowledge service and received 282 responses. The results of our empirical analysis show that 4('Continuous Attendance', 'Suggestion for the improving', 'Self-training', 'Favorable attitude') are positively related to the performance, but 2('Complying with the organizational value, policies, and regulations' and 'Protection') are not significant. In line with Fitzgerald (2006), we expect that participants in the virtual community may behave similarly to employees in the off-line firms for the high performance. But 2 behaviors have different results. The reason that the 'Complying with the organizational value' behavior is not sufficiently related to performance is that the motivation of participants is more related to intrinsic pleasure or altruism than external reward. Also, the 'Protection' behavior has no significant relationship with performance, which means that the high-performing participants have little concern about the problems in the community.

Objectives: This study investigates lay beliefs about the etiology and treatments of tic disorder and Tourette's syndrome, as well as identifying sociodemographic and personality variables affecting these beliefs among South Koreans. Methods: In total, 673 participants (mean age $41.77{\pm}12.03$ years) completed an online survey regarding their beliefs about tic disorder and Tourette's syndrome. The factors related to their lay beliefs about the disorders were analyzed, and the correlates were investigated. Results: Results indicated that lay people in South Korea held strong beliefs that the causes of tic disorder and Tourette's syndrome lie within the parenting/psychological and neurological/biological categories, compared to the dietary/environmental one. Among the sociodemographic variables, sex, age, and levels of subjective mental health knowledge were primarily associated with the aforementioned beliefs. Familiarity with tic disorder and Tourette's syndrome was also associated with these beliefs. Among the personality traits investigated, extraversion and conscientiousness had significant influences on the beliefs people had about tic disorder and Tourette's syndrome. Conclusion: The results suggest that both policy makers and mental health service providers should adopt a strategic approach for developing and implementing health education interventions about tic disorder and Tourette's syndrome because individual sociodemographic variables, familiarity with the disorders, and personality traits are all associated with the beliefs about these disorders.

This study purposed to discover whether or not academic libraries reflect these changing roles. We selected K University as the research target and surveyed user satisfaction of materials, staff services, facilities, electronic devices, media, and so on. The research findings are as follows: 1) the frequency of library visits of University K was on the high side, 2) the primary purpose of using the academic library was associated with learning or reading, therefore, the most used library spaces were related to that, 3) the most used library materials were 'general books', the most unused were 'reference books', 4) the most preferred way to obtain needed materials when failing to find wanted materials was 'Contact librarian'. A similar phenomenon occurred in terms of facility use, 5) university K's users were usually satisfied with the loan policy, 6) the rate of users who don't know whether there is user education was very high, the rate of users who have no experience with user education was extremely low. These research findings can be referenced by library management to improve libraries' service quality and take advantage of complex spatial configurations.

Despite its importance to Thailand, museum tourism has not received sufficient attention from researchers and practitioners. Consequently, knowledge of museum tourist responses toward museum service quality is quite limited. Thus, the purpose of this study was to (1) examine the service quality of museums in Thailand and (2) revealed how tourists react positively namely through satisfaction and revisit intentions. This study further explored how the proposed relationships vary between Asian and European tourists. Based on Harrison and Shaw's (2004) museum experience model, facilities, staff services, and exhibition experience were proposed as three important service elements encountered during a service experience. Data were collected from foreign tourists who visited any of the 6 national museums in Bangkok. A total of 260 questionnaires were obtained over a 3-month period, all of which were retained and utilized for the analysis. Results found that exhibition experience and staff services were positively associated with tourist museum visit satisfaction, which in turn acted on revisit intention. In addition, exhibition experience was found to be the most important service element for Asian tourists, while staff services was most important for European tourists. Staff services and exhibition experience both played important roles in the tourist museum experience, while facilities did not have an effect on the evaluation of museum services. In response, museum managers need to implement a segmentation strategy that considers tourists' backgrounds such as region, culture, or nationality.

The objective of this study was to analyze and to improve therapeutic drug monitoring(TDM) service of vancomycin in a local hospital. Patients with TDM service between September 2005 and December 2008 were included and the data were collected for vancomycin use and components of TDM. During that period, 421 cases of TDM service of vancomycin in 236 patients were retrospectively reviewed. The first dosages of vancomycin were appropriate in 135(57.2%) patients and administration of vancomycin was discontinued in 126(53.4%) patients due to therapeutic failure or adverse drug reaction. MRSA was identified in 191(80.9%) patients and 135(70.7%) samples for the identification were sputum. According to the TDM reports, 232(55.1%) serum samples were obtained at the steady-state conditions and 55.5% of the samples that were drawn before the steady-state was due to the physician's inappropriate knowledge about the steady-state. Based on the time of vancomycin administration, 35.8% of the samples were not obtained at the recommended sampling time. For the patients in general wards, the most common reason for the incorrect samples was routine serum sampling by the laboratory medicine phlebotomists between 6 and 8 a.m. except sunday. In contrast, samples drawn by nurses or physicians at inappropriate time were the most common reason for the incorrect samples with patients in the intensive care units. Physicians accepted 68.5% of the recommendations for vancomycin dosage and administration. In conclusion, TDM service of vancomycin needs to be improved in inappropriate sampling time and vancomycin dosage. For solving these problems, current team made of TDM pharmacists and physicians of laboratory medicine can be expanded to include a physician of infectious diseases, nurses and laboratory medicine phlebotomists as new members. Through the TDM service of vancomycin by the new team, we can settle the problems and make the guideline for the scientific controversies associated with therapeutic monitoring of vancomycin.
