Objective: Occupational medicine specialists in the Busan, Ulsan and Kyung-Nam areas established an area-based occupational disease surveillance system and used this system to collected case information for the purpose of preventing occupational diseases Methods: l l hospital participated in this system. The authors selected five main diseases, which were hand-arm vibration syndrome (HAVS), work-related musculoskeletal disorder (WRMSD), occupational asthma, occupational skin disease and occupational and occupational lung cancer and established their case definitions. All cases were reported on the web, and real time analysis was conducted. Results: Between April 2001 and April 2003, 192 cases of HAVS, 118 cases of WRMSD, 33 cases of occupational asthma, 17 cases of occupational skin disease and 17 cases of occupational lung cancer (for a total of 377 cases of these five main diseases) were reported. most of the HAVS cases came from shipbuilding, and 172 of them (92.7%) were associated with grinding. Of the four main types of WRMSD, carpal tunnel syndrome (CTS) was the most prevalent with 46 cases and shipbuilding was also the main industry involved (83.9%). The ergonomic risk factors involved mainly associated with the hand. In 19 (57.6%) and 4 (12.1%) cases of occupational asthma, the agents involved. The causative agents of occupational lung cancer included Cr, welding fume, PAH, Ni, etc. 10(58.8%) of the cases were diagnosed as squamous cell carcinoma and 5(29.4%) as adenoma. Conclusion: This result showed that an area-based occupational disease surveillance system might provide an effective method of evaluating the prevalence of such diseases, however the Busan, Ulsan and Kyung-Nam provinces are too large to be treated as individual areas. Therefore, the authors suggest that each province should establish its own surveillance system.

In Vitro Antiviral Activity of Ribavirin Against Severe Fever with Thrombocytopenia Syndrome Virus Myung Jin LEE1, Kye-Hyung KIM1, Jongyoun YI2, SuJin CHOI1, Chung-Jong KIM1, Nak- Hyun KIM1, Kyoung-Ho SONG1, Pyoeng Gyun CHOI1, Ji-Hwan BANG1, Wan Beom PARK1, Eu Suk KIM1, Sang-Won PARK1, Hong Bin KIM1, Nam Joong KIM1, Myoung- Don OH1 Seoul National University College of Medicine, Korea1, Pusan National University School of Medicine, Korea2 Background: Severe fever with thrombocytopenia syndrome (SFTS) is an emerging infectious disease caused by a novel Bunyavirus, severe fever with thrombocytopenia syndrome virus (SFTSV). No effective antiviral therapy is proven yet, but clinical use of ribavirin (RBV) has been tried. We investigated the antiviral effect of RBV against SFTSV in vitro. Methods: To test for cytotoxicity of RBV, Vero cells were treated with different concentrations of RBV (3.90 to 500 μg/mL, two-fold dilution) and analyzed by cell viability MTS assay 48h post-infection. To determine antiviral activity of RBV against SFTSV, Vero cells were infected with SFTSV strain Gangwon/Korea/2012 at 100 TCID50 (50% tissue culture infective dose) per well in a 96-well plate, and RBV was added at the concentrations showing no or minimal cytotoxicity. Viral RNAs were extracted from the culture supernatants and quantifi ed using one-step real-time reverse transcription- PCR to amplify the partial large segment of SFTSV. Statistical analysis was done by one-way ANOVA with Tukey`s post hoc test. Results: Cytotoxicity due to RBV was not observed at RBV concentration =31.3 μg/ mL. Viral RNAs at 24h post-RBV treatment were reduced with increasing RBV concentrations (1-32 μg/mL), compared with those of mock-treated cells (P <0.01, Figure). Half maximal inhibitory concentration (IC50) of RBV was 3.69 μg/mL at 24h post-RBV treatment. Conclusions: Our study shows that RBV has antiviral effect against SFTSV in a dose-dependent manner. Further studies are required to evaluate the effi cacy of RBV in SFTS.

이경준,김지태 한국특수체육학회 2005 한국특수체육학회지 Vol.13 No.1

The purpose of this study was to throughly identify the idea on inclusive physical education from the perspectives of people with disabilities. In order to accomplish this, critical ethnography was used. The key informants were the students(n=12) of Y University in Seoul, the members of the human rights society group for people with disabilities, 'Guernica'. The data were collected through the participant observation, in-depth-interview, unstructured interview and document analysis. The data were interpreted through the qualitative research procedures which are transcription, coding, categorization and conceptualization. The findings could be summarized as follows: First, although people with disabilities were treated inappropriately, they had positive attitudes on inclusive physical education and believed that it could reduce the bias toward people with disabilities. Second, the people with disabilities perceived inclusive physical education as a sport itself, not as a rehabilitation. Third, the precondition for the best inclusive physical education needs for the reform of consciousness in both people with and without disabilities.

The purpose of this study was to investigate disinfection state and effective factors of foodservice facilities and utilities of elementary schools in Busan area. Foodservice facilities and utilities investigated in this study were ceiling, wall, floor, trench, greasetrap, hood, pest and dumb waiter. The questionnaire which was administered to 196 dietitians was used as a survey method. The results were as follows. The washing method of foodservice facilities and utilities was mainly used by detergent washing-natural dry. The disinfection method of foodservice facilities and utilities was mainly sanitized by sodium hypochlorite. Dumb waiter and hood were sanitized by 70% ethyl alcohol and iodine. In washing and disinfection frequencies of foodservice facilities and utilities ceiling was twiceiyear, wall, hood and pest control facilities were once/week, floor, trench, greasetrap and dumb waiter were everyday, respectively. Floor, trench, greasetrap and dumb waiter were disinfected properly, whereas ceiling, wall, hood and pest were not disinfected properly. The washing method was related to dietitian's marital status and education. The disinfection state was related to dietitian's age and career, having of sanitation check list. The disinfection method was also affected dietitian' s marital status, number of employee, duration of foodservice, number of total serving and having of sanitation check list. Therefore based on the results of this study, it should be given to the microbiological study on disinfection of facilities and utilities such as ceiling, wall, floor, trench, greasetrap, hood, pest and dumb waiter and the dietitian and employee's sanitation training also should be conducted continuously.

연구 목적: 이 연구의 목적은 하악골 충격 시 안면 두개골의 응력 분산양상에 미치는 구강보호장치의 효과에 대해 조사하는 것이다. 연구 재료 및 방법:: 구강보호장치를 제작하고 사람의 머리부위와 치열의 3차원적 유한요소 모델을 컴퓨터 토모그래피를 사용하여 제작하였다. 머리부위의 finite element model은 356,092요소와, 87,099절점으로 이루어져 있다. 그리고 skull과 maxillae, mandible, articular disc, teeth, 그리고 구강보호장치로 구성되었다. 경부의 움직임을 묘사하기 위하여 스프링이 사용되었다. 하악골의 충격점은 gnathion, center of inferior border 와 anterior edge of gonial angle이었다. 충격방향은 수직, 경사방향(45 도), 그리고 수평이다. 충격량은 0.1초당 800 N이었다. 결과: 수직충격을 가한 경우에는 구강보호장치의 장착여부와 무관하게 비슷한 응력과 분산양상이 나타났다(P>.05). 경사충격(45 도)을 가한 경우 구강보호장치를 장착한 모델에서는 응력이 치아와 안면골 및 두개골로 넓게 분산되었으나 이에 비하여 장착하지 않은 모델에서는 치아에 응력이 집중되었다(P<.05). 수평충격을 가한 경우 구강보호 장치를 장착한 모델에서는 응력이 치아와 안면골 및 두개골로 넓게 분산되었으나 이에 비하여 장착하지 않은 모델에서는 치아에 응력이 집중되었다(P<.05). 구강보호장치를 장착하지 않은 모델에서는 상악 치아에 응력이 집중되는 반면, 장착한 모델에서는 모든 충격실험에서 계측된 응력이 매우 낮았으며, 전달된 응력이 상악 치아와 안면골 및 두개골로 넓게 분산되었다. 결론: 구강보호장치는 외부충격 시에 하악에 수직으로 가해지는 충격에는 완충효과가 적었고, 45 도 경사 충격과 수평 충격에는 발생하는 응력을 안면골과 두개골의 넓은 범위로 분산시키고 응력을 감소시켜 응력의 완충 효과가 있었다. PURPOSE. The purpose of this study was to investigate the effects of a mouthguard on stress distribution under mandibular impact. MATERIALS AND METHODS. The FEM model of head consisted of skull, maxilla, mandible, articular disc, teeth, and mouthguard. The impact locations on mandible were gnathion, the center of inferior border, and the anterior edge of gonial angle. And the impact directions were vertical, oblique (45 degrees), and horizontal. The impact load was 800 N for 0.1 sec. RESULTS. When vertical impact was applied, the similar stress and the distribution pattern was occurred without the relation of the mouthguard use (P>.05). The model with mouthguard was dispersed the stress to the teeth, the facial bone and the skull when the oblique (45 degrees) impacts were happened. However, the stress was centralized on the teeth in the model without mouthguard (P<.05). The model with mouthguard was dispersed the stress to the teeth, the facial bone and the skull when the horizontal impacts was occurred. However, the stress was centralized on the teeth without mouthguard (P<.05). For all impact loads, stress concentrated on maxillary anterior teeth in model without mouthguard, on the contrary, the stress was low in the model with mouthguard and distributed broadly on maxillary anterior teeth, facial bone, and skull. CONCLUSION. The mouthguard was less effective at shock absorbing when vertical impact was added. However, it was approved that mouthguard absorbed the shock regarded to the oblique (45 degrees) and horizontal impact by dispersing the shock to the broader areas and decreasing the stress.

조현이,정종철,김호성,최재욱,성대경,서지훈,김성범,이계혁 大韓顎顔面成形再建外科學會 2000 Maxillofacial Plastic Reconstructive Surgery Vol.22 No.1

Osteosarcoma is a primary malignant tumor arising most often in the long bone, but rare in jaw bone. Especially osteogenic sarcoma of the mandible is a rare tumor, comprising less than 0.5% of all head and neck tumors. Osteosarcoma occurs cheifly in young persons, and presenting very survival rates. Histopathologically this tumor can be classified three types, osteoblastic, fibroblastic, chondroblastic and classified from low grade to high grade by anaplasia or mitosis of the tumor cells. Sometimes, the exact diagnosis of osteosarcoma is difficult especially in low grade osteosarcoma, even if clinical or radiographical findings suggest to osteosarcoma. So suspcious to malignant bone tumor in clinical or radiological findings, biopsy should be taked from deep portion and multiple area, and sharing the patient history and radiographs with pathologist will assist in the development of the diagnosis. We report a case of low grade osteosarcoma on the mandible initially difficulty in accurate diagnosis. The patient visited our hospital for routine dental treatment but radiographic findings displayed ill-defined radiolucency with osteoid formation on the mandible. Final diagnosis was difficulty in initial biopsy but subsequent biopsy taked from deep portion presented infiltrative growth and mitosis of the tumor cell in some area with small osteoid bone formation, so we could reach final diagnosis as low grade sarcoma. We treated this patient with bloc resection of the mandible and immediate reconstruction with iliac corticocancellous block.

Conflicts between individuals are quite natural and they can act as an positive contributing factor not only to the development of an individual but also to the organization to which one belongs. But too much conflicts will always induce dissatisfaction and stresses, which will be destructive and harmful to all of them, and that is why we are always tying to seek(find) out the causes for the origination of conflicts and remedies to cope with them effectively. The present study, as the first one in a series of studies which our researchers contemplate executing, was designed to develop a measure of job satisfaction for dental laboratory technicians. One job satisfaction measure and two job satisfaction related measures, one for faithfulness for the job and the other for environmental characteristics of dental laboratory were newly developed. The newly developed measures were comprised of a total of 38 items, which were each 12 items for job satisfaction and faithfulness for the job and 14 items for environmental characteristics of dental laboratory With the aid of factor analysis for principal components and categorization of items by panel of professionals, items of each measure were grouped into 2-4 subscales. Contribution to internal consistency was the fina) criterion for an item's inclusion in a subscale. Internal consistency reliability of each item was attested through the statistical analysis on the data obtained from 55 structured questionnaires. Reliability of internal consistency of subscales in each measure of job satisfaction and faithfulness for the job ranged from 0.74 to 0.79 and 0.90-0.91 respectively. The result from this research came to draw the following conclusions. 1. Validity and internal consistency reliability of all the items of each measure was attested. 2. The newly developed measure of job satisfaction was found to be appropriate for (measuring the degree of job satisfaction of) dental technicians, as well as for (other) dental office personnels.

본 연구는 진로정체감 검사의 중고등학생 규준을 설정하기 위한 것이다. 우리나라 중고등학생의 진로정체감 점수는 학년에 따라 일관성 있게 상승하는 것이 아니었기 때문에 각 학년에 따른 규준점수가 제시되어야만 상담과 생활지도에서 유용한 도구로 사용될 수 있다는 점에 착안하였다. 우리나라 전국의 중고등학생 1640명의 자료를 분석하였다. 중고등학생의 진로정체감 수준은 7.6으로 나타났고 학년에 따라서 차이가 있었다. 상담과 생활지도의 실제에서 각 점수에 맞는 진로탐색활동과 상담이 제공될 수 있도록 남녀별, 학년별로 진로정체감검사의 백분위 점수와 T점수를 제시하여 규준으로 활용하도록 하였다. The present study was conducted to make a norm of score of Career Identity in Korea Middle and High School Students. This study was interested to offer the data for effective career guidance and counseling in the schools, counseling centers. The Vocational Identity(Ⅵ) scale was developed by Holland, Daiger, and Power (1980). Vocational identity can be defined as an awareness of and ability to specify one's own interests, personality traits, strengths, and goals as related to career choices. It is brief and self-administered and can be completed individually or in groups. The 1,640 students were sampled from national level, which were randomly sampled. The instrument for study was Ⅵ(Vocational Identity), which from My Vocational Situation(MVS). MVS was developed by Holland, Daier power(1980) and adapted by Bong-Whan Kim. For hypothesis and verification, the collected data were analyzed using the SPSS PC+. T-test and one way analysis of variance(ANOVA) were used to analyse of difference between gender and grade. The result of the present study were as follows : (1) Vocational Identity score in middle school students is more high than the high school students. The average of the Vocational Identity in middle school students is 7.9, and in the high school students is 7.2. (2) The norm of Vocational Identity score was presented.
