Background: Cervical cancer is a major public health problem in Bangladesh. Persistence of high risk human papillomavirus (HRHPV) influences the progression of the disease, with an important role in followup for cervical intraepithelial neoplasia (CIN). Objective: To establish application of high risk HPV DNA test in the follow-up of women after treatment of CIN. Materials and Methods: This cross-sectional and hospital based study was carried out among 145 CIN treated women during the previous six months to three years at the colposcopy clinic of Bangabandhu Sheikh Mujib Medical University, Dhaka, between January 2011 and June 2012. Pap smear and HPV samples were collected and colposcopy was performed to find out the persistence of the disease. Cervical samples obtained were tested for HPV DNA using the Hybrid Capture II (HC-II) test. A cervical biopsy was collected whenever necessary. The results were compared to assess the efficacy of different methods during follow up such as Pap smear, HPV test and colposcopy. Results: Mean age of the recruited women (n=145) was 33.6 (${\pm}7.6$), mean age of marriage was 16.8 (${\pm}2.9$) and mean age of 1st delivery was 18.8 (${\pm}3.5$) years. More than half had high grade CIN before treatment and 115 (79.3%) women were managed by LEEP and 20.7% were managed by cold coagulation. Among the 145 treated women, 139 were negative for HPV DNA and six of them (4.1%) were HPV positive. Sensitivity of Pap smear (40.0) and HPV DNA test (40.0) was poor, but specificity was quite satisfactory (>93.0) for all the tests. Conclusions: The high risk HPV DNA test can be an effective method of identifying residual disease. It can be added to colposcopy and this should be applied to all treated women attending for their first or second post-treatment follow-up visit at 6 months to one year, irrespective of the grade of treated CIN.

Objective : This study was designed to compare the efficacy of micro-vascular decompression (MVD) and Gamma knife radiosurgery (GKRS) for elderly idiopathic trigeminal neuralgia patients by analyzing the clinical outcome. Methods : In the past 10 years, 27 elderly patients were treated with MVD while 18 patients were treated with GKRS (>65-years-old). We reviewed their clinical characteristics and clinical courses after treatment as well as the treatment outcomes. For patients who were treated with MVD, additional treatment methods such as rhizotomy were combined in some areas. In GKRS, we radiated the root entry zone (REZ) with the mean maximum dose of 77.8 (70-84.3) Gy and one 4 mm collimator. Results : The mean age was 68.1 years for MVD, and 71.1 years for GKS group. The average time interval between first presenting symptom and surgery was 84.1 (1-361) months, and 51.4 (1-120) months, respectively. The mean follow-up period after the surgery was 35.9 months for MVD, and 33.1 months for GKRS. According to Pain Intensity Scale, MVD group showed better prognosis with 17 (63%) cases in grade I-II versus 10 (55.6%) cases in GKRS group after the treatment. The pain recurrence rate during follow up did not show much difference with 3 (11.1%) in MVD, and 2 (11.1%) in GKRS. After the treatment, 2 cases of facial numbness, and 1 case each of herpes zoster, cerebrospinal fluid (CSF) leakage, hearing disturbance, and subdural hematoma occurred in MVD Group. In GKRS, there was 1 (5.6%) case of dysesthesia but was not permanent. Three cases were retreated by GKRS but the prognosis was not as good as when the surgery was used as primary treatment, with 1 case of grade I-II, and 1 case of recurrence. The maximal relieve of pain was seen just after surgery in MVD group, and 1 year after treatment in GKRS group. Conclusion : For trigeminal neuralgia patients with advanced age, MVD showed advantages in immediately relieving the pain. However, in overall, GKRS was preferable, despite the delayed pain relief, due to the lower rate of surgical complications that arise owing to the old age.

This study intended to find out how the handicapped use medical aid, their satisfaction at using it and so on. First a preliminary survey(Apr. 20$\sim$24, 2002) was made for the handicapped who had been cured for rehabilitation by wearing medical aid at hospitals and welfare center in Jeonbuk region. Then total 120 subjects were asked to fill out a standardized questionnaire from May 15$\sim$22, 2002. Out of total 95 questionnaires collected, 84 questionnaires were analyzed except for 11 cases unsuitable for the intention of this study. The results can be outlined as follows: 1. In general characteristic, it was found that the causes of disability included disease(35 respondents; 41.7%), traffic accident(23 respondents, 27.4%) and so on. In addition, 1st handicap comprised the majority(32 respondents; 58.2%) in handicap grade and ankle foot orthosis(or b-k orthosis) was most often used as medical aid(28 respondents: 33.3%) 2. In particular, it was also shown that the 1st handicap mainly resulted from traffic accident(15 respondents, 27.3%) and post-disease disability (11 respondents, 20.0%). They wore medical aid for 1 year or less on the average, because they were hospitalized for cure, which showed statistically significant level(P<0.05). 3. It was found that total 69 respondents(82.1%) were more or less satisfied with their medical aids depending on the causes of disability, and total 46 respondents(83.6%) were satisfied with their aids according to their handicap grade, but there were no statistical significance. 4. Total 56(66.7%) respondents answered that they would purchase medical aid on their own expenses, when they became handicapped. And the price of medical aid ranged from $\300,000{\sim}400,000$(25 respondents: 29.8%) to \ 500,000 or more(24 respondents: 28.6%). It means that they purchased more or less expensive medical aid on their own expenses, which showed statistical significance(P<0.05). 5. If there was any failure of medical aid, 9 respondents(37.5%) answered that they would be serviced from medical companies, and 7 respondents(29.2%) would be serviced from medical aid manufacturers. Most respondents were serviced for their medical aids from related companies. For the question about the causes of dissatisfaction upon repair service, 11 respondents(45.8%) answered that existing service company provided unskilled repair services and other respondents answered that there was no spare part or higher service expenses than they thought. These answers had the statistical significance(P<0.05). However, 20 respondents(79.2%) answered that they were satisfied with the repair service, which means that most respondents are satisfied with the service. In view of the results as described above, it can be concluded that their handicap or disability results from disease or sequelae after traffic accident and most of the affected wear their own medical aid. In the future, it is required that the medical insurance should cover those medical aids, and the service for failed medical aids should be commissioned by technical serviceman to realize customized manufacture and repair service according to different causes so that the handicapped can enjoy more or less comfort and convenience in their daily lives without any extreme difficulty.

Purpose: Re-irradiation (re-RT) is considered a treatment option for inoperable locoregionally recurrent head and neck cancer (HNC) after prior radiotherapy. We evaluated the efficacy and safety of re-RT using Helical Tomotherapy as image-guided intensity-modulated radiotherapy in recurrent HNC. Materials and Methods: Patients diagnosed with recurrent HNC and received re-RT were retrospectively reviewed. Primary endpoint was overall survival (OS) and secondary endpoints were locoregional control and toxicities. Results: The median follow-up period of total 9 patients was 18.7 months (range, 4.1 to 76 months) and that of 3 alive patients was 49 months (range, 47 to 76 months). Median dose of first radiotherapy and re-RT was 64.8 and 47.5 $Gy_{10}$. Median cumulative dose of the two courses of radiotherapy was 116.3 $Gy_{10}$ (range, 91.8 to 128.9 $Gy_{10}$) while the median interval between the two courses of radiation was 25 months (range, 4 to 137 months). The response rate after re-RT of the evaluated 8 patients was 75% (complete response, 4; partial response, 2). Median locoregional relapse-free survival after re-RT was 11.9 months (range, 3.4 to 75.1 months) and 5 patients eventually presented with treatment failure (in-field failure, 2; in- and out-field failure, 2; out-field failure, 1). Median OS of the 8 patients was 20.3 months (range, 4.1 to 75.1 months). One- and two-year OS rates were 62.5% and 50%, respectively. Grade 3 leucopenia developed in one patient as acute toxicity, and grade 2 osteonecrosis and trismus as chronic toxicity in another patient. Conclusion: Re-RT using Helical Tomotherapy for previously irradiated patients with unresectable locoregionally recurrent HNC may be a feasible treatment option with long-term survival and acceptable toxicities.

Accidents involving children are an important cause of death and disability. They also have enomorous financial implications. In order to prevent childhood accidents, research and education for safety should be strengthened. The purpose of this study was to determine how often young children have accidents and what factors affect the accident rate. The sample consisted of 771 children who were in the second, third and forth grades of two elementary schools located in Kyung-gi Province. One school had students from middle class families living in apartment complexes and the other, students from lower income families mainly living in single houses. The questionnaires included items on the occurance of accidents and the parents' attitudes regarding accidents during the academic year from March 1997 to February 1998. The Questionnaires were distributed to conventiently selected students to be compeleted by their parents and collected during the period of May 28, to June 6, 1998. The data were analyzed using SAS PC statistical package. The results of the study are as follows ; 1. Of 771 student subjects, 393 had 887 accidental injuries during the study period. 2. The month, the day and the time with the highest accident rate were May, Sunday, and between 1 and 4 p. m. each. 3. In the analysis of the location where the injury took place, the most frequent place was on around their homes followed by school and, then, inside the home 4. Most of the accidents were caused by carelessness on the part of the children and the most frequent type of injury was an abrasion. 5. Children most injured their legs 6. They were treated at home most often and usually emergency treatment was performed by family members with, disinfection being the main type of first aid. Cost of the treatment ranged from 8,000 to 20,000 won in most cases. 7. House type and parents' education level were statistically significant in chi-square analysis. 8. Parents educate their children about traffic safety most frequently followed by fire safety and, then, prevention of violence. 9. Parents think that prevention of violence should be the most important part of injury prevention education both at school and home. 10. To identify factors related to accident occurrence, multiple logistic regression was performed and the main factors were birth order and house type.

본 연구는 교사 질문, 말하기 차례 규칙, 학생 발화 사이의 관계를 파악하고자 수학 교실 내의 언어적 상호작용을 분석하였다. 이를 위해 같은 학교에 근무하고 있는 세 명의 초등학교 교사들(1학년 교사 2명과 2학년 교사 1명)의 수학 수업을 대화분석 기법을 사용해서 분석하였다. 각 교사들의 수업은 일 년에 걸쳐 총 3회 관찰되었다. 분석 결과, 교사가 열린 질문(예를 들어 "왜" 그리고 "어떻게" 질문들과 "동의합니까" 그리고 "동의하지 않습니까" 질문들)을 사용하고 비전통적인 말하기 차례 규칙(교사발문-학생답변-교사 피드백; Mehan, 1979)을 사용하였을 때는 학생들이 자신의 생각을 정당화하고 다른 사람의 생각을 반박하기 위해 교실 담화에 보다 적극적으로 참여하여하는 것으로 나타났다. 하지만, 교사가 닫힌 질문(예를 들어 "무엇" 질문들)을 사용하고 전통적인 말하기 차례 규칙을 사용하였을 때 학생들은 정답을 말하는 것에만 관심을 갖고 짧은 발화만을 사용하는 것으로 드러났다. 본 연구의 시사점은 다음과 같다. 첫째, 교사들은 효과적인 수학-대화 학습공동체를 만들기 위해 열린 질문을 사용하고 비전통적인 말하기 차례 규칙을 사용해야 한다. 둘째, 교사들이 발화기법에 관한 실질적인 지식을 얻을 수 있도록 교육 행정가와 수학 교육자들이 지원해야 한다.
