The short-term music therapy was performed for adolescents with conduct disorder admitted to Seoul National Mental Hospital for 3 months from Jun to September, 1998. This case study focused mainly on two female patients who participated regularly in the group music therapy. The music therapy process was divided into three phases；beginning, opening up, and closing. This music therapy session consisted of three parts；hello song as beginning, various musical activities, and sound & movement activity as closing. Free musical improvisation, song discussion, musical monodrama, and sound & movement were the mainly applied techniques. Free improvisation was used to enhance, motivate, identify and contain the adolescents' feelings and ideas. Song discussion was used to convey their thoughts and to support each other. Musical monodrama was used to make them have insights into interpersonal relationships. Sound & movement was used to enhance spontaneity. It made them explore their body and voice as an expressive medium. Throughout three months period of music therapy, patient A's communication skill, socialization, and behavior areas were assessed with improvement. She could use music as a symbolic form and was able to share her feelings about herself and her family. Patient B's self-expression and cognitive areas were assessed with improvement. She became more spontaneous and could verbalize her emotions during the group session. Music as a non-verbal and therefore often a non-threatening medium wherein so much can be expressed provided two female patients an atmosphere where a sense of trust may be regained.

Objective : The purpose of this study was to investigate the relationship between the pattern of computer game play and emotional and behavioral characteristics of 5th and 6th grade elementary school children in Jeonju city. Methods : Fifth and sixth graders from two elementary schools (N=413, M=214, F=199) were chosen to participate in this study. The participants completed self-report questionnaires designed by the authors, and were also evaluated based on a computer game addiction scale, state-trait anxiety inventory for children, children's depression inventory and Piers-Harris children's self-esteem scale. The parents of the participants determined the disruptive behavior rating scale of the participants. Results : Positive links were reported between the pattern of computer game play (years of computer game experience, average length of each computer game play session, average time spent on computer game play per day, and average frequency of computer game play per week) and scores of computer game addiction scale. In addition, significant correlation was found between the internalized problems of children (trait anxiety, state anxiety, depression, and self-esteem), and computer game addiction scale score, among both sexes (p<0.01). There were significant correlations between game addiction scale score and inattention (p<0.01) as well as total attention deficit hyperactivity disorder (ADHD) score (p<0.05) in girls. Conclusion : Our findings suggest that computer game addiction is related to symptoms of internalizing, particularly to the trait anxiety. Significant positive correlations between game addiction scale score and externalized behavioral problems were found only in girls.

The security industry for civilians (Private Security), was first introduced to Korea via the US army's security system in the early 1960's. Shortly after then, official police laws were enforced in 1973, and private security finally started to develop with the passing of the 'service security industry' law in 1976. Korea's Private Security industry grew rapidly in the 1980's with the support of foreign funds and products, and now there are thought to be approximately 2000 private security enterprises currently running in Korea. However, nowadays the majority of these enterprises are experiencing difficulties such as lack of funds, insufficient management, and lack of control over employees, as a result, it seems difficult for some enterprises to avoid the low production output and bankruptcy. As a result of this these enterprises often settle these matters illegally, such as excessive dumping or avoiding problems by hiring inappropriate employees who don't have the right skills or qualifications for the jobs. The main problem with the establishment of this kind of security service is that it is so easy to make inroads into this private service market. All these hindering factors inhibit the market growth and impede qualitative development. Based on these main reasons, I researched this area, and will analyze and criticize the present condition of Korea's private security. I will present a possible development plan for the private security of Korea by referring to cases from the US and Japan. My method of researching was to investigate any related documentary records and articles and to interview people for necessary evidence. The theoretical study, involves investigation books and dissertations which are published from inside and outside of the country, and studying the complete collection of laws and regulations, internet data, various study reports, and the documentary records and the statistical data of many institutions such as the National Police Office, judicial training institute, and the enterprises of private security. Also, in addition, the contents of professionals who are in charge of practical affairs on the spot in order to overcomes the critical points of documentary records when investigating dissertation. I tried to get a firm grasp of the problems and difficulties which people in these work enterprises experience, this I thought would be most effective by interviewing the workers, for example: how they feel in the work places and what are the elements which inpede development? And I also interviewed policemen who are in charge of supervising the private escort enterprises, in an effort to figure out the problems and differences in opinion between domestic private security service and the police. From this investigation and research I will try to pin point the major problems of the private security and present a developmental plan. Firstly-Companies should unify the private police law and private security service law. Secondly-It is essential to introduce the 'specialty certificate' system for the quality improvement of private security service. Thirdly-must open up a new private security market by improving old system. Fourth-must build up the competitive power of the security service enterprises which is based on an efficient management. Fifth-needs special marketing strategy to hold customers Sixth-needs positive research based on theoretical studies. Seventh-needs the consistent and even training according to effective market demand. Eighth-Must maintain interrelationship with the police department. Ninth-must reinforce the system of Korean private security service association. Tenth-must establish private security laboratory. Based on these suggestions there should be improvement of private security service.

Objective：This study was designed to investigate the difference between executive function of Attention Deficit/Hyperactivity Disorder(ADHD) group and that of neurotics, and to investigate the developmental aspects of ADHD group's executive function. Method：Executive function between ADHD(N=87) and Neurotics(N=19) was evaluated through their performance on the Wisconsin Card Sorting Test. The results were analyzed by 2-way ANOVA and t-test. Results：The results revealed group difference between ADHD and neurotics in total correct reponses, total error responses, nonperseverative errors, number of categories completed, conceptual level responses. There was no significant difference between the performance of 8-12 aged group and 13-15 aged group. But 7-8 aged group showed significantly poor performance than 8-12 aged in total responses, total error responses, perseverative responses, perseverative error responses, nonperseverative error responses. Conclusions：In comparison to the neurotics group, the children of ADHD group are suggested to be lacking the ability to correct their responses according to the external feedback and they probably respond randomly without self-control. However, as there is no difference between perseverative errors and perseverative responses, the interpretation of this finding warrants caution. It also suggests that the developmental aspects should be considered in the studies of executive functions because there are differences in the performance of executive functions by ages.

Purpose : We studied the prevalence of snoring and its association with diseases, obesity and environmental factors, as well as sleep disturbance arising from snoring, in school-aged children. Methods : The survey was performed by a special questionnaire on 1,707 children at elementary schools from 1 to 30 July 2001 in Gwangju City. The prevalence of snoring, associated factors, and sleep disturbance were evaluated. Results : 266(16.5%) of the children snored at least once a week. 73(4.3%) of the children snored almost every day. Regarding the associated factors of snoring : There was a statistically significant difference between snoring and nonsnoring groups due to gender, obesity, sinusitis, tonsillar hypertrophy, bronchial asthma and allergic rhinitis. Of them, male gender, tonsillar hypertrophy, and obesity were significant risk factors for development of snoring. Especially, the odds ratio increased to 1.048(CI, 1.004-1.659), 1.748(CI, 1.175-2.599), and 2.266(CI, 1.300-3.950) in children with an obesity index of 20-29%, 30-49%, ${\geq}50%$, respectively. There was a statistically significant association of snoring with decreased sleep duration, sleep talking, and drowsiness during the day as a result of sleep disturbance. Conclusion : 16.5% of school-aged children snored at least once a week. The association of snoring with tonsillar hypertrophy, obesity and gender as risk factors was demonstrated in this study.

Purpose : To determine whether primary snoring could be distinguished from obstructive sleep apnea syndrome (OSAS) by clinical evaluation and symptom scores. Methods : 56 snoring and 20 asymptomatic subjects were recruited and polysomnography was used to confirm that there were 39 OSAS, 17 primary snoring, and 20 control subjects. We evaluated the size of the childrens adenoids and tonsils. Parents completed sleep disordered breathing scale (SDBS) and obstructive sleep apnea 18 (OSA-18) questionnaires for use as symptom scores, as well as an attention deficit hyperactivity disorder rating scale-IV (ADHD RS-IV). Results : There were no differences between primary snoring and OSAS in terms of tonsil and adenoid size, SDBS ($9.4{\pm}4.6\;vs\;10.8{\pm}4.5$), and OSA-18 score ($61.1{\pm}25.1\;vs\;71.2{\pm}8.4$). The patients with OSAS ($15.8{\pm}7.9$) and PS ($22.2{\pm}9.4$) had a higher ADHD RS-IV score than the control subjects ($2.9{\pm}3.3$). There was no difference in the ADHD RS-IV scores of patients with primary snoring and OSAS. Conclusion : We confirmed that clinical evaluation could not distinguish OSAS and primary snoring. In addition, our study suggests that primary snoring as well as OSAS is associated with attention deficit hyperactivity disorder.

Objectives：This study was conducted to develop a Korean algorithm of pharmacological and non-pharmacological treatment strategies in attention-deficit hyperactivity disorder (ADHD) and its specific comorbid disorders (e.g. tic disorder, depressive disorder, anxiety disorder, bipolar disorder, and oppositional defiant disorder/conduct disorder). Methods：Based on a literature review and expert consensus, both paper- and web-based survey tools were developed with respect to a comprehensive range of questions. Most options were scored using a 9-point scale for rating the appropriateness of medical decisions. For the other options, the surveyed experts were asked to provide answers (e.g., duration of treatment, aver-age dosage) or check boxes to indicate their preferred answers. The survey was performed on-line in a self-administered manner. Ultimately, 49 Korean child & adolescent psychiatrists, who had been considered experts in the treatment of ADHD, vol untarily completed the questionnaire. In analyzing the responses to items rated using the 9-point scale, consensus on each option was defined as a non-random distribution of scores as determined by a chi-square test. We assigned a categorical rank (first line/preferred choice, second line/alternate choice, third line/usually inappropriate) to each option based on the 95% confidence interval around the mean rating score. Results：Specific medication strategies for key clinical situations in ADHD and its comorbid disorders were indicated and described. We organized the suggested algorithms of ADHD treatment mainly on the basis of the opinions of the Korean experts. The suggested algorithm was constructed according to the templates of the Texas Child & Adolescent medication algorithm Project (CMAP). Conclusion：We have proposed a Korean treatment algorithm for ADHD, both with and without comorbid disorders through expert consensus and a broad literature review. As the tools available for ADHD treatment evolve, this algorithm could be reorganized and modified as required to suit updated scientific and clinical research findings.

Purpose: A primary adenosquamous carcinoma of the stomach is relatively rare, accounting for only about 0.5% of all gastric cancers. However, its histopathologic characteristics are still unclear, and the most appropriate form of therapy has not been established yet. Materials and Methods: We retrospectively reviewed the clinicopathologic features of 8 patients with pathologically confirmed primary adenosquamous carcinomas out of 8,268 patients who underwent gastric cancer surgery at Samsung Medical Center between September 1994 and December 2004. Results: The median age of the 8 patients was 49 ($41{\sim}69$) years, and the male : female ratio was 5 : 3. In 3 patients, the tumor was located at the mid body of the stomach, and in 5 patients, at the lower body or antrum. The tumor sizes were $2.5{\sim}8cm$. Seven patients showed metastases to the regional lymph nodes. The UICC stage distribution were: 5 stage II, 2 stage III, and 1 stage IV. In the stage IV patient, a palliative gastrojejunostomy was performed, and he died 5 months after surgery. Of the 7 patients who underwent a radical gastrectomy and adjuvant chemotheratpy, the median survival was 34 ($12{\sim}66$) months, 2 patients died of cancer recurrence, and 4 patients are being followed up without evidence of recurrence. Conclusion: As for an adenocarcinoma of the stomach, a radical gastrectomy including regional lymph node dissection and postoperative adjuvant therapy should be performed for appropriate treatment of an adenosquamous carcinoma of the stomach.

Objective : The present study investigated the effects of group play activities based on Ayres Sensory $Integration^{(R)}$ (ASI) on sensory processing ability, social skill ability and self-esteem of low-income children with attention deficit hyperactivity disorder (ADHD). Methods : A total of 20 low-income participants with children with ADHD were recruited and divided into an experimental group (n=10) and a control group (n=10). Sensory processing ability was measured via the Short Sensory Profile (SSP). Social skill ability was measured via the Social Skills Rating System (SSRS). To measure self-esteem, the Rosenberg's self- esteem scale was used. The experimental group received the $ASI^{(R)}$ group play activities for 50 minutes, twice per week for six weeks, while the control group did not receive an intervention. Level of significance of all statistical analyses was .05. Results : Social skill ability (F=4.443, p=.05), cooperation (F=5.328, p=.035) and self-esteem (F=5.358, p=.033) differed significantly between groups after the intervention. Conclusion : Our findings indicate that the group play activities based on $ASI^{(R)}$ are effective in improving social skill ability and self-esteem. This study provided a theoretical basis for the claim that sensory integration therapy should be applied in general elementary schools.
