Purpose : To assess the tolerance, complete response rate, bladder preservation rate and survival rate in patients with muscle-invading bladder cancer treated with selective bladder preservation protocol. Method and Materials : From October 1990 to June 1998, twenty six patients with muscle-invading bladder cancer (clinical stage T2-4, N0-3, M0) were enrolled for the treatment protocol of bladder preservation. They were treated with maximal TURBT (transurethral resection of bladder tumor) and 2 cycles of MCV chemotherapy (methotrexate, crisplatin, and vinblastine) followed by $39.6\~45\;Gy$ pelvic irradiation with concomitant cisplatin. After complete urologic evaluation (biopsy or cytology), the patients who achieved complete response were planed for bladder preservation treatment and treated with consolidation cisplatin and radiotherapy (19.8 Gy). The patients who had incomplete response were planed to immediate radical cystectomy. If they refused radical cystectomy, they were treated either with TURBT followed by MCV or cisplatin chemotherapy and radiotherapy. The median follow-up duration is 49.5 months. Results : The Patients with stage T2-3a and T3b-4a underwent complete removal of tumor or gross tumor removal by TURBT, respectively. Twenty one out of 26 patients $(81\%)$ successfully completed the protocol of the planned chemo-radiotherapy. Seven patients had documented complete response. Six of them were treated with additional consolidation cisplatin and radiotherapy. One patient was treated with 2 cycles of MCV chemotherapy due to refusal of chemo-radiotherapy. Five of 7 complete responders had functioning tumor-free bladder. Fourteen patients of incomplete responders were further treated with one of the followings : radical cystectomy (1 patient), or TURBT and 2 cycles of MCV chemotherapy (3 patients), or cisplatin and radiotherapy (10 patients). Thirteen patients of them were not treated with planned radical cystectomy due to patients' refusal (9 patients) or underlying medical problems (4 patients). Among twenty one patients, 12 patients $(58\%)$ were alive with their preserved bladder, 8 patients died with the disease, 1 patient died of intercurrent disease. The 5 years actuarial survival rates according to CR and PR after MCV chemotherapy and cisplatin chemoradiotherapy were $80\%\;and\;14\%$, respectively (u=0.001). Conclusion : In selected patients with muscle-invading bladder cancer, the bladder preservation could be achieved by MCV chemotherapy and cisplatin chemo-radiotherapy. All patients tolerated well this bladder preservation protoco. The availability of complete TURBT and the responsibility of neoadjuvant chemotherapy and chemoradiotherapy were important predictors for bladder preservation and survival. The patients who had not achieved complete response after neoadjuvant chemotherapy and chemoradiotherapy should be immediate radical cystectomy. A randomized prospective trial might be essential to determine more accurate indications between cystectomy or bladder preservation.

A multidisciplinary weight control program was conducted for obese women. The major components of the program included low calorie diet therapy, exercise, behavior modification and nutritional education and counseling. Sixteen healthy volunteers in excess of body fat, above 30%, were enrolled in the group support program. But 5 person were dropped out in the 2nd week of treatment. During the 1st week of group orientation, individual cause of obesity was assessed through a computer program including survey of dietary intake, activity, eating habits and life styles. During the 5 weeks of treatment, 4.8kg of average weight loss was accomplished using a following program ; low calorie diet(1200kcal/day with all essential nutrients), low impact aerobic exercise(50~60% of $VO_{2max}$, 1 hour/day in a group, 3~5 days/week), behavior modification of individual life styles and eating habits causing obesity and nutritional education concerning nutrition, role of exercise such as brisk walking, importance of slow eating in regular meal pattern and internal motivation for weight reduction, health risk of obesity and rapid weight loss, weight recycling and yo-yo syndrome, etc. Nutritional conseling was conducted 3 times per week with checking self-records of foods, activity, emotional state and tiredness. Before and immediately after 5 weeks of treatment, blood pressure, fasting blood glucose, cholesterol and triglyceride were measured and comparied with paired t-test. After 5 weeks of treatment, body weight, body mass index, body fat and circumferences of waist, upper arm and hip were significantly decreased. Also LDL-cholesterol was significantly decreased after obesity treatment.

This study analyzed the structure and utilization of subject headings in the National Library of Korea Subject Headings List (NLSH) based on an analysis of subject headings assigned to 1,218,867 national bibliographies from 2003 to 2022. The findings of the study are as follows: Firstly, among all subject headings in the NLSH, there were 257,103 preferred terms, accounting for 50.2% of the total terms. Foreign language terms constituted 33% (169,466), while non-preferred terms comprised 12% (61,442). Among the preferred terms, 57,312 subject headings were used, accounting for 22.3%. However, it was observed that 54.7% (31,351) of these subject headings were assigned less than 5 times, indicating that only a small number of subject headings were frequently utilized. Secondly, the frequency of relationship indicators appeared in the order of RT, BT, and NT. The NLSH consisted of 12,602 top-level subject headings and 143,704 lowest-level subject headings, with a maximum depth of 17 levels. Thirdly, on average, 1.72 subject headings were assigned per bibliographic record. The number of subject headings assigned and the depth of the hierarchy increased for materials with more specific contents. Recent bibliographic records have been assigned more subject headings and deeper into the hierarchy of the NLSH. It was also found that the number of subject headings assigned per bibliography varied depending on the main class of KDC. Based on the findings, it is recommended to evaluate the coverage of terms in the NLSH, reorganize hierarchical relationships and depth of subject headings, and enhance the development of subdivisions within the NLSH.

Purpose : This is a retrospective study to evaluate the response rate, acute toxicity, and survival rate of a combined chemotherapy and radiation therapy in limited disease small cell lung cancer, Materials and Methods : Firty-six patients with limited disease small-cell lung cancer who underwent combined chemotherapy and radiation therapy between October 1994 and April 1998 were evaluated. Six cycles of chemotherapy were planned either using a VIP regimen etoposide, ifosfamide, and cis-platin) or a EP regimen (etoposide and cis-platin). Thoracic radiation therapy was planned to deli- ver 44 Gy using 1 OMV X-ray, starting concurrently with chemotherapy. Response was evaluated 4 weeks after the completion of the planned chemotherapy and radiation therapy, and the prophylaetic cranial irradiation was planned only for the patients with complete responses. Acute toxicity was evaluated using the SWOG toxicity criteria, and the overall survival and disease-free survival were calculated using the Kaplan-Meier Method. Results : The median follow-up period was 16 months (range:2 to 41 months). Complete response was achieved En 30 (65$\%$) patients, of which 22 patients received prophylactic cranial irradiations. Acute toxicities over grade III were granulocytopenia in 23 (50$\%$), anemia in 17 (37$\%$), thrombo- cytopenia in nine (20$\%$), alopecia in nine (20$\%$), nausea/vomiting in five (11$\%$), and peripheral neuropathy in one (2$\%$). Chemotherapy was delayed in one patient, and the chemotherapy doses were reduced in 58 (24$\%$) out of the total 246 cycles. No radiation esophagitis over grade 111 was observed, while interruption during radiation therapy for a mean of 8.3 days occurred in 21 patients. The local recurrences were observed in 8 patients and local progressions were in 6 patients, and the distant metastases in 17 patients. Among these, four patients had both the local relapse and the distant metastasis. Brain was the most common metastatic site (10 patients), followed by the liver as the next common site (4 patients). The overall and progression-free survival rates were 79$\%$ and 55$\%$ in 1 year, and 45'/) and 32% in 2 years, respectively, and the median survival was 23 months. Conclusion : Relatively satisfactory local control and suwival rates were achieved after the combined chemotherapy and radiation therapy with mild to moderate acute morbidities in limited disease small cell lung cancer.
Purpose : This is a retrospective study to compare the Palliation rates, survival rates and complications of low dose rate and high dose rate endobronchial brachytherapy in the management of malignant airway obstruction. Materials and methods : Forty three consecutive patients with malignant airway compromise from primary or metastatic lung tumors were treated with low dose rate(LDR) endobronchial Iridium-192 insertion(21 patients) between October 1988 and June 1992, and high dose rate(HDR) endobronchial brachytherapy(22 patients) between August 1992 and April 1994 with palliative aim Flexible fiberoptic bronchoscopy under fluoroscopic control was utilized in all 91 procedures. Twenty seven LDR Procedures delivered a dose of 5-7.5 Gy to a 1.0 cm radius respectively. Results : Subjective and objective responses to treatments were evaluated on follow-up examinations by clinical examination, chest x-rays and CT scan of the chest on some patients. Fifteen of 21 LDR patients and 19 of 22 HDR Patients showed subjective improvement in terms of better breathing and less Productive cough as well as complete disappearance of hemoptysis. Objective improvement on chest x-rays and CT scan of the chest had been demonstrated on 8 LDR Patients and 10 HDR patients. Conclusion : The technique of LDR and HDR endobronchial brachytherapy is simple and well tolerated procedure with minimal morbidity It Provides excellent palliation by keeping airway Patent in these short life-spanned patients.
The present study was attempted to compare duality in value structure and judgment system between youth, adults and North Korean defectors. A questionnaire was administered to 150 college students(Men: 89, Women: 61), 155 adults(Men: 80, Women: 75) and 80 North Korean defectors(Men: 39, Women: 41). Participants rated their values, behavior and South Korean behavior (or North Korean behavior for North Korean defectors) as a whole both on the 7 dimensions relevant to characteristics indigenous to Korean society and on their opposite 7 dimensions characteristic of Western culture. Results indicated that defectors marked the highest score on the traditional value dimensions, and yet youth ranked the first for the western value systems. Also, duality in value systems was the most severe for the defectors. In relation to dual judgement system in behavior, both young and old generation judged Korean behavior more negatively than their own. This was also the case for the North Korean defectors. Those findings were discussed in terms of cultural changes in Korean society.
The Cultural Heritage Committee is an advisory committee established under the Cultural Heritage Administration with the aim of carrying out examination and deliberation on preservation, management and use of cultural heritage. The Cultural Heritage Administration is the highest administrative organization in terms of Korean cultural heritage. It was founded to produce and execute policies on cultural heritage, an important task that requires a high level of specialized knowledge, skills and academic expertise. It involves in-depth investigation and consultation of experts in the field of cultural heritage. An organization consisting of distinguished experts, the Cultural Heritage Committee plays an important role in policymaking on cultural heritage of Korea. The Korean government established the Bureau of Cultural Heritage in October 1961, and enacted provisions (as a presidential decree) on the organization on March 27, 1962, according to the Cultural Heritage Act established on January 10 of the same year. The Cultural Heritage Committee was opened as a deliberation committee according to the law, on which currently 90 members serve in 8 subcommittees. The term of office of a committees member is two years. The deliberation of the committee, which covers the entire range of cultural heritage, including their designation and cancellation, is normally concluded by the deliberation and decision of each subcommittee. This study aims to analyze of the survey of the Cultural Heritage Committee as the highest organ for the deliberation of policies on the matters of cultural heritage. The subject of the analysis in this study is a questionnaire survey that was conducted between Oct. 20 and Nov. 29, 2003, of 116 former and current members of the committee.
The purpose of this study was to demonstrate the effectiveness of walking and band exercise for 12 weeks on c-reactive protein and cardiovascular disease risk factor in overweight and obese children. Body composition, blood lipids, insulin sensitivity, c-reactive protein (CRP) were assessed before, after 4 weeks and after 12 weeks of combined exercise. Sixteen participants (BMI${\geq}$21.3) were randomly allocated to exercise group (n=8) and control group (n=8). The exercise group participated in 50 minutes of walking exercise and band exercises as resistance training two days a week for 12 weeks. There were significant different on weight (p<0.001), BMI (p<0.001), fat mass (p<0.001), fat percentage (p<0.001), LBM percentage (p<0.001), TG (p<0.05), HDL-C (p<0.01), insulin (p<0.05), HOMA-IR (p<0.05) in exercise group after intervention. And the change of weight (p<0.001), BMI (p<0.001), fat mass (p<0.001), fat percentage (p<0.001), LBM mass (p<0.05), LBM percentage (p<0.001), insulin (p<0.05), HOMA-IR (p<0.05) were significant difference between groups after intervention. These findings suggest that 12 weeks of walking and band exercise can be useful intervention in the improvement of cardiovascular disease risk factor in overweight and obese children. But c-reactive protein was no change.
