Background and purpose : Drug abuse is one of the most serious problems among the Korean adolescents today and has been associated with delinquent behavior in adolescents. The number of adolescents who abuse drugs is increasing yearly. Solutions to the problem, however, have not been well developed. The purpose of this study was to determine the effectiveness of a drug use prevention program which was developed by researchers. The program was a modified DARE(Drug Abuse Resistance Education) program for Korean adolescents. Methods: This study used an experimental, one-group pretest-posttest design with a convenience sample of 122 middle school students who were at one middle school located in Seoul. Data were collected using a self-administered questionnaire where ‘knowledge and attitude about drug use’, ‘social skill’, and ‘self-esteem’ were measured. The program had 12 sessions to improve knowledge and attitudes towards drugs, decision making skills, social resistance skills, management of stress and self-esteem of students. Teaching strategies for each session were varied lectures, group discussion. role-playing, question-and-answer sessions and audiovisual materials. Paired t-test was used to analyze the differences between the pre- and post-test scores on knowledge of and attitudes towards drug use, social skills, and self-esteem. Results : There were significant differences in knowledge and attitudes about drug use between pretest and post-test (p＜.05), but no significant differences in social skill and self-esteem(p＞.05). Conclusion: Our results showed that the drug use prevention program was not effective in promoting social-skill and self-esteem of Korean adolescents. These findings might be due to the respondents being in the period of early adolescence (puberty) and not being good at group discussion. So, further study is needed to develop a drug use prevention program appropriate to students 9 and 10 years old, and to encourge small group discussion.

The campus has been composed of a very variety buildings. However, there is almost no easy way to see information about room number of each floor of the buildings and all buildings. For that reason, in this paper, we have developed a 3D simulation system for the 3D visualization of campus building information. Each building and cross section of floor was modeled in 3D based on the actual drawing. And texture mapping were using real photos. The user interface was divided into frames for menu and 3D viewer. When you select a building name from the menu, 3D viewer shows the selected building by zooming. And menu frame is shown the various information related to the building. Also when you select a room number of each floor, a separate web browser shows the cross section by VRML viewer. Conversely, when you click on the building in the 3D viewer, menu frame is shown the various information related to the building. This system is very useful in that provide realistic building information of campus.

The study aimed to evaluate the effects of the magic program on the depression and self-esteem in rural low-income children. A quasi-experimental study employing a nonequivalent control group and pre-post design was conducted. The participants were children aged 9 to 12 years old from community child center in K province (Experimental group=24, Control group=21). The experimental group participated in the program for 8 sessions for 8 weeks. Data were analyzed using ${\chi}^2$-test, independent t-test, repeated measures ANCOVA with SPSS 21.0 program. There were significant differences in depression (F=6.68, p=.013) and self-esteem (F=7.61, p=.009) of participants between experimental group and control group after completion of 8-session magic program. The results indicate that the magic program can be used to improve depression and self-esteem of low-income children.

We introduce a new satellite Conditional Access System(CAS) that a subscriber could watch a pay-TV knowing only his or her identity and password, without using a smart card. For this new system, two password-based protocols are presented which not only share a session key and authenticate each other but also download an authorization key. This system has some merits: First, compared with current systems, it reduces the amount of computations by eliminating the AK-encryption module in SMS(Subscriber Management System) and simplifying the receiver's CW-decryption process. Second, since this system does not need an expensive Card Adaptive Device(CAD), it can reduce costs. finally it provides descrambler independence allowing it to be used through any TV set-top box that includes a descrambler, unlike the current system that a descrambler is linked with a smart card.

Purpose: A botulinum toxin type A (BoNT - A) injection has been used as a noninvasive management for lower face contouring since 2000. The aim of this study was to compare reduction rate of lower face width for a longtime according to repeated Botox$^{(R)}$ injections on masseter muscles for lower face contouring procedure. Methods: Forty - five patients were analyzed for single session of Botox$^{(R)}$ injection and 13 patients were evaluated for repeated Botox$^{(R)}$ injections for over two years. Single injection group was tracked regular intervals at 1, 3, 6, 10, 12 months after injection, and repeated injection group was measured at every injection time. Twenty - five to thirty units of Botox$^{(R)}$ was injected into each masseteric muscle at five to six points at the prominent portions of the mandibular angle. Standardized frontal view of digital photographs were analyzed by Adobe Photoshop$^{(R)}$ (version CS3) to measure an reduction rate of lower face width. Results: Reduction rate was 3.7%, 6.9%, 6.2%, 4%, 4% at 1, 3, 6, 10, 12 months post injection each other in single injection group. However, more than 8% reduction rate was found in repeated injection group persistently for more than two years. Conclusion: This study shows that effective duration of Botox$^{(R)}$ injection for lower face contouring is expected to continue over one year clinically. Moreover, repeated injections maintained lower reduction rate consistently for a long time. Therefore, repeated injections on masseter muscles at regular intervals are most effective procedure for lower face contouring.

In this paper, using the Android App to remote database monitoring system is proposed. Existing remote database monitoring scheme CS(Client / Server) based. Conventional CS based systems are space constraints and a plurality of administrator to access the database at that degrade performance disadvantages. The advantage of the proposed system first, because the web -based interface allows the application program, and also the ease of maintenance, through a web browser, if you have Internet access anytime, anywhere environment without restrictions of time and space monitoring. Second, the proposed system because the App -based technology due to an increase in connection session and query execution does not affect the performance of your database. Third, if there is a problem with the remote database through which social networks immediately notify the administrator of the smartphone in real time so that the administrator can identify the problem.

The purpose of this study is to examine the effects of spiritual education for spiritual care competence reinforcement of nursing students. 83 subjects of nursing students were participated in two universities located in J city(from February 27 to May 19, 2017) and composed of 42 in the experimental group and 41 in the control group. The spiritual education was composed of three sections; self-awareness, spirituality, and spiritual dimension in nursing. This program was then implemented on the subjects for a total of 10 sessions with each session lasting 120 minutes and given 2 times a week for 5 weeks. The data collected were analyzed for descriptive statistics, χ2-test, Independent t-test and Repeated ANOVA. This spiritual education increased the spirituality, ego-identity, spiritual well-being, satisfaction with life, and spiritual care competence of the nursing students. The effectiveness of the spiritual education also maintained in five weeks after intervention. It is therefore proposed that this education be utilized for the nursing students as basic standardization process of a spiritual nursing care.
