This study examined living rehabilitation teachers of disability facilities in Kyungkido to determine the status of the personal and oral hygiene of the disabled. The results are as follows. First, the personal hygiene of residential disabled people was positively correlated with voluntary toothbrushing, recognition of the importance of toothbrushing, and finding of their own toothbrush. Second, the difficulties related to the oral hygiene practice of residents with disabilities were found to be carrying out abnormalities in their toothbrush and oral examinations at dental medical institutions. In addition, in the spontaneous performance, they did not do well in gum massage and in restraining sugary foods. Third, voluntary toothbrushing was positively correlated with training on toothbrushing, and toothbrushing for more than 3 minutes and the rolling method toothbrushing were positively correlated with the supplement of oral health materials. Therefore, a dental hygiene management program is required continuously for living rehabilitation teachers and the disabled.

This study aims to evaluate the impact of forest therapy on neuro-cognitive, psychosocial, and physiological aspect of adolescent internet addiction risk group. We have classified potential and high risk user group as internet addiction risk group according to the criteria of Korean Internet Addiction Proneness Scale(K Scale). Based on the results of k-scale from the adolescents in metropolitan area from May to July 2013, 25 people were selected as Internet addiction risk group. We have randomized 13 participants joining forest therapy camp and 12 participants not joining one, and analyzed the change of the two groups with Continuous Performance, Kimberly S. Young, Connor-Davidson Resilience, Relationship Change Scale, heart rate variability and cortisol. Statistically significant changes were observedd in neuro-cognitive, psychosocial, and physiological variables, Through this study, we can consider that the therapy healing may relieve the level of internet addiction and can be an alternative to control emotional stability and impulsive behavior.

The purpose of this study was to analyze the perceptions to improvement directions of related regulations for water leisure activation. In order to accomplish such study purpose, the study utilized a survey methodology with 205 water leisure participants and 117 water leisure business employees. In addition, this study attempted to review the license and education system, registration and inspection system and business organizations from the advanced countries such as US, British, Australia and Japan. Accordingly, following findings were derived from current study. First, the problems of current license system included difficulty of operating the system and deficiency of operating organizations, and the improvement directions included expansion of education organizations and differentiation of education based on levels. Second, the improvement directions of registration and inspection included simplification of registration procedures and expansion of registration and inspection organizations. Third, difficulties perceived by business employees included complexity of entry and departure, complexity of registrating water leisure business and insufficiency of supporting business policies. In conclusion, water leisure related regulations including Water Leisure Safety Act need to be reformed continuously to reflect changing demands and needs from participants and business sectors.

Objectives：For the purpose of obtaining the more vivid present status and prevention program of teenage pregnancy, this survey was done by Obstetricians, as study subject, who manage the pregnant teenager in real clinical situation. Methods：Structured survey form about teenage pregnancy was sent to 2,800 obstetricians. That form contained frequency, characteristics, decision making processes, and psychiatric aspects of the teenage pregnancy. 349 obstetricians replied that survey form and we analysed these datas. Results：(1) The trend of teenage pregnancy was mildly increased. (2) The most common cases were unwanted pregnancy by continuing sexual relationship with boyfriends rather than by forced, accidental sexual relationship with multiple partners. (3) The most common reason of labor was loss the time of artificial abotion. (4) Problems of pregnant girls' were conduct behaviors and poor informations about contraception rather than sexual abuse or mental retardation. (5) Most obstetricians percepted the necessity of psychiatric consultation, however psychiatric consultation was rare due to parents refusal and abscense of available psychiatric facility. (6) For the prevention of teenage pregnancy, the most important thing was practical education about contraception. Conclusions：Based on the result of this study, further study using structured interview schedule with pregnant girl is needed for the detecting risk factor of teenage pregnancy and effective systematic approach to pregnant girl.

공장(정)자동화에 대한 산업현장의 요구가 증대되고 다양한 자동제어 기술이 발전, 적용되면서 이 분야에 대한 중요도는 날로 커져가고 있다. 산업설비 및 공정 자동화에 가장 널리 적용되고 있고 중추적인 역할을 수행하고 있는 제어기가 바로 프로그래머블 논리 제어장치, PLC이다. 그러나 PLC 프로그램을 작성하여 실제로 기계나 설비에 적용하기 위해서는 PLC 프로그램의 논리적인 오류 등을 검사하고 수정하는 등의 작업이 필요한데 자동화 시스템에서 이를 직접 적용하기에는 많은 위험부담과 비용부담이 뒤따른다. 한편, 눈부신 발전을 거듭한 PLC 제어 기술에 데한 전문지식을 보유한 인력에 대한 산업현장의 요구는 꾸준히 지속되고 있는 추세이나 지금까지 교육기관에서 실시되고 있는 PLC 제어기술에 관련된 교육은 해당 시스템에 대한 거시적 이해 위주의 이론교육 형태로 실시되어 왔다. 이러한 산업적 측면과 교육적 측면의 문제점을 해결하고 자동화, 자동제어 교육에 대한 학생들의 흥미와 실무능력 향상을 위하여 본 논문에서는 현장에서 활용되고 있는 기기와 시스템을 모의할 수 있는 자동화 설비의 가상 플랜트 시뮬레이터와 PLC 프로그램을 편집하고 모니터할 수 있는 도구를 개발하여 종합적이고 현장감 있는 교육을 가능하게 하는 방법을 제안하였다.

Compared with traditional face-to-face instruction, online learning causes learners to experience more severe feeling of isolation and results in higher dropout rate. This is due to the lack of interaction, sense of belonging, membership, interdependency, cooperation among members and social environment that enables persistence in online learning. Therefore, it is very important for grouping e-learning community to lower the dropout rate and eliminate feeling of isolation. In this paper, the research has been done on the inclination test list to be applied for grouping the desirable learning community. And on the basis of this research, the grouping system for e-learning community(GSE) based on intelligent multi agents for an inclination test using homogeneous and heterogeneous items has been developed. GSE system has such properties that construct a personalized user profile by an agent, and then make groupings according to users' inclination. When this system was evaluated, about 88% of learners were satisfied, and they wanted the group not to be disorganized but to be maintained.

The increasing use of computed tomography (CT) as a diagnostic tool creates the need from and efficient means of evaluating the performance of the CT scanner now in use. Accordingly, acceptance testing and quality assurance of CT is of great importance. The aim of this study is to analyze of AAPM CT performance phantom in the CT accreditation program. The modular phantom offers the CT system with which to measure eight performance parameters. The parameters are listed of CT attenuation coefficient of water, noise, uniformity, spatial resolution, contrast resolution, slice thickness (5 and 10 mm), artifacts and alignment. The phantom evaluation was done by two radiologists. The acceptance testing protocol described here in demonstrates the successful of the guidelines for the quality assurance using AAPM CT performance phantom. We need to be upgraded for the CT image quality and make the standard reference of the quality assurance in the CT.

A 10 year old, intact female Yorkshire terrier was referred to the Veterinary Teaching Hospital of Konkuk University. Upon admission, the patient had severe necrotic skin disease on face and abdominal wall, and also showed polyuria, polydipsia (PUPD), and polyphagia. A tentatative diagnosis of hyperadrenocorticism was made on the basis of history takings, physical examination, and results of CBC and serum biochemistry. Hyperadrencorticism was confirmed by ACTH stimulation test and pituitary-dependent hyperadrenocorticism (PDH) was diagnosed according to the results of high dose dexamethasone suppression test (HDDST). After initiating mitotane therapy, severe skin problem and clinical signs including PUPD were improved. And we determined whether or not mitotane therapy well controlled serum cortisol level with ACTH stimulation test. This case was presented to show that the patient misdiagnosed and treated for more than 1 year as other dermatologic problem in 3 local animal clinics was treated and managed sucessfully with mitotane administration.
