Recently, in Korea, construction of high-rise buildings has been rapidly increasing. Therefore, in order to minimize the loss of life and property in the event of a fire, "performance-based design" which requires performance equal to or better than current regulations is obligatorily required. However, in the field of fire and evacuation simulation, which occupies a large part in the performance-based design, detailed technical guidelines have not yet been established. Therefore, various designers are proceeding with the computer simulation modelling by referring to the design report book previously performed. Especially, in the case of the fire simulation, according to the judgment of a designer the scenario type is selected and the input values is set. Even if the building is used for the same purpose, it is true that the result can be different depending on how and who designed it. Therefore, in this paper, we have investigated the fire scenarios type and scenarios input values by randomly examining 7 preliminary reports of performance-based design in B metropolitan city. We also propose the improvement strategy for fire simulation and lay the groundwork for establishment of technical guidelines for fire simulation for performance-based design.

Objective : The purpose of this study was to establish a school-based mental health intervention. The success of which was indexed by its effects on the social anxiety symptoms of the enrolled adolescents. Methods : This program for promoting mental health among adolescents in the community was adopted by three middle schools that volunteered to participate in the project. The program included screening for emotional problems related to social anxiety, depression, suicide, and post-traumatic stress disorder. Case management was provided for groups considered high-risk for depression, suicide, or post-traumatic stress disorder; cognitive-behavior therapy was provided for those at high-risk of developing social anxiety. Additionally, educational programs for the prevention of suicide, a "loving life" module, and mental health promotional campaigns were also included. In total, 1,100 middle school students completed self-report questionnaires. Twenty-five students in the high-risk group for social anxiety participated in a cognitive-behavior therapy program, comprising eight sessions, and conducted by two clinical psychologists. Results : Following the suicide prevention education program, suicide awareness among students increased and coping strategies were improved. In addition, the loving life program was associated with positive self-perceptions by many students. Furthermore, social anxiety symptoms showed a statistically significant difference after the cognitive-behavior therapy program. After the therapy, not only did social anxiety symptoms improve, depressive symptoms and suicidal ideation decreased significantly, while self-esteem and psychological resilience significantly increased. Conclusion : A school-based mental health intervention was successfully implemented in three middle schools and improved the mental health of the participating students. Therefore, this intervention could be widely implemented to promote positive mental health among middle school students.

Spinocerebellar ataxias (SCAs) are autosomal dominant neurodegenerative disorders which disrupt the afferent and efferent pathways of the cerebellum that cause cerebellar ataxia. Spectrin beta non-erythrocytic 2 (SPTBN2) gene encodes the ${\beta}-III$ spectrin protein with high expression in Purkinje cells that is involved in excitatory glutamate signaling through stabilization of the glutamate transporter, and its mutation is known to cause spinocerebellar ataxia type 5. Three years and 5 months old boy with delayed development showed leukodystrophy and cerebellar atrophy in brain magnetic resonance imaging (MRI). Diagnostic exome sequencing revealed that the patient has heterozygous mutation in SPTBN2 (p.Glu1251Gln) which is a causative genetic mutation for spinocerebellar ataxia type 5. With the patient's clinical findings, it seems reasonable to conclude that p.Glu1251Gln mutation of SPTBN2 gene caused spinocerebellar ataxia type 5 in this patient.

This study is a trend analysis study that discusses the current status and directions of research methods of KAP research. The existing trend ana lysis studies dealing with research methods have problems in that the classification criteria of the studies used are rough and different from each other, rendering comparison between studies being difficult, and do not comprehensively cover research methods of diversified KAP research. Therefore, this study examined the research methods of KAP research from a critical point of view and suggested a set of classification criteria and an analysis framework that can be used consistently in classification and analysis of future KAP research methods. Based on the theoretical background of second language studies and applied linguistics, this study revised and supplemented Brown (2015)'s research method types and selected 289 journals and theses/dissertations from 2012 to 2016 and classified them into a new analysis framework. The primary and secondary studies, which are the major categories, were 219 and 70, respectively, so it was confirmed that there were much more primary studies. The primary studies then were subdivided into 128 qualitative research studies, 142 survey research studies, and 23 quantitative research studies, pointing to the trend that survey and qualitative research methods were preferred. In the qualitative research approaches, there were 21 action research studies, which were used the most. In addition, such qualitative research approaches as case studies and narrative inquiries which were difficult to find in the past, have gradually increased, confirming that the diversification of research methods is becoming common. However, there were still many studies that did not explicitly put forward research questions and there were many studies that did not report reliability and effect sizes in quantitative research. Of the 23 quantitative studies, only 50% reported reliability, and only three reported effect sizes. In order to enable systematic reviews (meta-analysis) of quantitative research and expect quality improvement of research in future KAP research, reporting of quantitative research should be done more systematically. This study is meaningful in that a systematic and detailed analysis framework was proposed to classify various research methods in the future and that the problems and directions for improvement of the KAP research methods were discussed through the analysis of the research trend of the KAP studies for the last 5 years.

Tuberous sclerosis complex (TSC) is an autosomal dominant disorder caused by mutation of one of two genes, TSC1 (encoding hamartin, 9q34) and TSC2 (encoding tuberin, 16p13). It invades the central nervous system and various parts of the body, causing various symptoms. Crohn's disease (CD) is a chronic immune-mediated disease that has not been clearly elucidated. It is thought to be caused by an excessive immune response of the body to bacteria that normally exist in the digestive tract with genetic factors. No cases have been reported in which both of the above-mentioned diseases occurred simultaneously. We report a case of CD in a patient with TSC. A 12-year-old boy was brought to our hospital because of abdominal pain. Skin lesions were observed in the TSC. Fundus examination revealed a hamartoma in the right retina. Brain magnetic resonance imaging revealed a subendothelial giant cell astrocytoma (SEGA). On the basis of these findings, he was diagnosed as having TSC. Blood test results showed increased levels of inflammatory markers. On abdominal ultrasonography, his colon walls were observed to be thickened with increased vascularity of the proximal ascending colon, ileocecal valve, and terminal ileum. Colonoscopy revealed discontinuous ulcerations and inflammations of the ileum, IC valve, and cecum, similar to those found in CD. Everolimus was administered orally for the SEGA but was discontinued frequently owing to the exacerbation of CD. The possibility of CD should be kept in mind in patients with TSC considering to undergo treatment for SEGA.

Qualitative management and certification of higher education and higher education programs are important in Australia and Hong Kong. The purpose of the study is to analyze the higher educational Institute accreditation in Australia and Hong Kong and to provide basic data for the domestic evaluation accreditation system For this purpose, the analysis was conducted based on the analysis framework of Kis(2005), which was modified by the researchers in Tertiary Education Quality and Standards Agency(TEQSA) and Hong Kong Council for Accreditation of Academic and Vocational Qualifications(HKCAAVQ). The quality assurance approach in Australia and Hong Kong is common as 'accreditation' and focuses on other evaluation methods, evaluation data, nature of the report, evaluation purpose, evaluation result, and follow-up evaluation. Australia and Hong Kong had separate evaluation agencies for accreditation of higher education qualifications, degrees, and educational programs, and were performing accreditation at the independent institutions. Australia and Hong Kong do not agree with the evaluation standards of higher education institutions because of different academic system and qualifications system from Korea. Higher education institutions need to consider international interchange in terms of exchanging higher education human resources between countries. It is also necessary to conduct evaluation of higher education institutions with reference to higher education quality management standards.

Excessive tooth wear can cause irreversible damage to the occlusal surface and can alter the anterior occlusal relationship by destroying the structure of the anterior teeth needed for esthetics and proper anterior guidance. The anterior deep bite is not a morbid occlusion by itself, but it may cause problems such as soft tissue trauma, opposing tooth eruption, tooth wear, and occlusal trauma if there are no stable occlusal contacts between the lower incisal edge against its upper lingual surface. The most important goal of treatment is to form stable occlusal contact in centric relation. In this case report, patients with decrease in vertical dimension and anterior deep bite due to maxillary posterior tooth loss and excessive tooth wear were treated full mouth rehabilitation with increased vertical dimension to regain the space for restoration and improve anterior occlusal relationship and esthetics. The functional and aesthetic problems of the patient could be solved by the equal intensity contact of all the teeth in centic relation (CR), anterior guidance in harmony with the functional movement, and restoration of the wear surface beyond the enamel range.

The purpose of this study was to examine whether the gender, grade and school type of middle school students made any differences to their sexual awareness and sexual behaviors in an effort to lay the groundwork for providing more efficient sex education. The research questions were posed as follows: First, what is the sexual awareness of middle school students? Second, what are the sexual behaviors of middle school students? Third, are their gender, school year and school type related to their sexual awareness and behaviors? The subjects in this study were 976 middle school students from Gyeonggi province. After a survey was conducted with questionnaires prepared by this researcher based on earlier studies to suit the purpose of the study, the collected data were analyzed with SPSS 10.0 program. The frequency analysis, x2 test and correlational analysis were implemented, and basic statistical data were obtained. The conclusions were as follows: First, regarding their sexual awareness, the largest group of them agreed that one must report in case of being raped(4.36), and the smallest number of them thought that one might have a sexual relationship with a person other than his or her spouse after marriage(1.56). Second, as for experience of indecent materials, part of sexual behaviors, 67.4 percent had ever contacted such materials. The most common medium through which they contacted them was the Internet(56.5%). The above-mentioned findings suggested that the sexual awareness of the middle school students wasn't influenced by gender or school type. But that varied with grade, as the third graders had the best sexual consciousness. Their sexual behaviors were different according to gender. The boy students contacted more indecent materials, and their experience of such materials varied with grade, since the third graders contacted the most obscene materials. And that also varied with school type, and the non-engineering students contacted more obscene materials. As for sexual drives, their masturbation experience was different according to gender, grade and school type. The number of the boys who practiced masturbation was four-fold larger than that of the girls, and the second graders had more such experience. By school type, the non-engineering students practiced more masturbation, but there was no significant gap between their kissing, caressing and dating experiences.

Full-mouth rehabilitation with increasing vertical dimension can be used for patients with severely worn teeth. In severely worn teeth also, the alveolar process can be elongated to compensate for the reduced vertical dimension, and the patient's vertical dimension of occlusion can be kept constant. However, full-mouth rehabilitation with increasing vertical dimension must be carefully chosen, because the vertical dimension can be reduced by tooth wear. It is important to establish a treatment plan with the systematic diagnosis of the change in the vertical dimension and gain space for the prosthesis. It is necessary to change the vertical dimension to secure the restoration space and select the minimum vertical dimension elevation for the esthetic and functional goal. In this case report, the patient complained of difficulty during chewing due to a worn dentition and wanted esthetic improvement of the short mandibular anterior teeth. After systematic evaluation and diagnosis, we performed full-mouth rehabilitation with minimum vertical dimension elevation to obtain the space for restoration. This resulted in a stable and harmonious occlusion, and the functional and esthetic problems of the patient were solved after treatment. The patient was satisfied with the results of the treatment and maintained stable occlusion during the follow-up period.
