The occurrence of a mixed tumor containing papillary thyroid carcinoma (PTC) and primary squamous-cell carcinoma (SCC) is rare because there is no squamous epithelium in the thyroid gland. Reported herein is a 30-year-old female with mixed PTC and primary SCC of the thyroid presented as thyroid incidentaloma. Fine-needle aspiration biopsy of the thyroid nodule revealed the presence of malignant thyroid cells. The histopathological examination following total thyroidectomy yielded two mixed, morphologically distinct histotypes that included PTC and SCC. After total thyroidectomy, the patient underwent radioactive iodine therapy. No recurrence or metastasis occurred during the 20-month follow-up period after the operation.

제1대구치는 막중한 역할을 함에도 불구하고, 청소년 이전에 건강을 상실하는 경우가 드물지 않다. 본 연구는 청소년기 이 전에 치수치료를 받게 된 제1대구치의 우식 및 수복 상태와 분포를 파악할 목적으로 시도되었다. 최근 5년간 부산대학교 치 과병원에서 치수치료를 받은 18세 이하 106명 환자의 135개 제1대구치를 대상으로 의무기록에 대한 조사를 시행하여 다음 과 같은 결과를 얻었다. 1. 평균 연령은 11.9세(남 11.5세, 여 12.5세)였고 유의한 성차를 보였으며(p<0.05), 악별로는 상악 47개, 하악 88개로 하악 치아가 더 많았다. 2. 치수 치료 전 치료 기왕력이 없는 치아는 74개, 치수 또는 수복 치료를 받은 치아는 61개였다. 그 중 재치수치료를 받게 된 경우는 22개로 치수절제술-치수절단술의 순이었으며, 단순 수복치료를 받았던 치아는 39개로 복합레진-아말감-GI- 인레이-수복물 탈락 후 미치료-열구전색 및 주조 전장관의 순이었다. 3. 병소 위치가 분류 가능한 73개의 병소 중에서는 근심면 병소가 22개, 교합면 혹은 협설면 병소 39개, 원심면 병소가 12 개를 차지하였다. In clinical dentistry, it is not difficult to meet the permanent first molars with severe coronal caries lesions in children or adolescents. The circumstances surrounding the first molars of children and adolescents are so immature and imperfect compared with those of adults. So we thought it significant to understand the status of these teeth at the moment of endodontic treatment and immediate cause of it. 106 patients with 135 permanent molars necessitating endodontic treatment in childhood and adolescence were included in this study, and the dental records and radiographs were examined. 1. The mean age was 11.9 year (male 11.5, female 12.5) and the result shows significant difference between gender(p<0.05). The mandibular teeth took more than half percentage than maxillary teeth. 2. Of 135 teeth, 45.2 percent of teeth had history of dental treatment previously and 16.3 percent of teeth showed necessity of re-endodontic treatment. 3. Of 73 teeth, 22 teeth had mesial-wall cavity causing endodontic treatment, 39 had occlusal cavity, and 12 had distal cavity.

태순호,이병곤 社團法人 韓國火災 ·消防學會 1998 한국화재소방학회논문지 Vol.12 No.4

고온에 노출된 콘크리트 미세조직의 변화가 강도에 미치는 영향을 규명하기 위하여 현재 건설현장에서 가장 많이 이용하고 있는 배합비와 쇄석으로 시험체를 제작하여 고온에 노출시킨 후 SEM/EDX, XRD 및 DSC-TG로 분석하여 각 온도별로 강도와 미세조직 특성을 분석하였다. Very often, whether accidentally or intentionally set fire, according as building are elevated, varied or complicated day by day. It is of primary importance that we have a treatment of fire damaged structure. In general, strength and elasticity modulus of heated concrete are reduced. Product background of cement, sand and coarse aggregate differ from country to country, so that thermal behaviour of concrete make a difference in high temperature. To cope with demand, this paper is a study on relation to microstructure and strength reduction. In consequence of experiments, concrete exposed to high temperature are estimating the reduction of mechanical properties in comparison with microstructure characteristics which are abtained from the SEM/EDX, XRD and DSC-TG analysis of heated specimens under various temperature.

김순한,임이종,최경숙,정영기,장경립,이태호 한국미생물생명공학회 ( 구 한국산업미생물학회 ) 1996 한국미생물·생명공학회지 Vol.24 No.2

Bioemulsifier를 생산하는 미생물을 토양으로부터 screening하였다. 그 중에서 유화활성과 유화안정성에서 가장 우수한 BE-254 균주를 순수분리하여 동정한 결과, Acinetobacter속으로 판명되었다. Bioemulsifier 생산을 위한 최적배지 조성은 n-hexadecane 4%, NaNO_3 0.2%, KH_2PO_4 0.05%, MgSO_4·7H_2O 0.05%, CaCl_2 0.01%, yeast extract 0.01%이였으며, 최적온도와 pH는 각각 30℃와 7.0이였다. 이러한 조건에서 500㎖용 shaking flask에 최적배지 50㎖를 넣어 배양했을 경우 대수증식기 말기인 5일째 균의 증식과 유화활성이 가장 높게 나타남에 따라 Acinetobacter sp. BE-254에 의한 bioemulsifier의 생산은 균의 생육과 밀접한 관련이 있는 것으로 판단되었다. 유화기질로서 hydrocarbon류, edible oil류, 그리고 petroleum fraction등에 작용시켰을 경우 이들 물질에 대해서 비교적 높은 활성을 나타내어 유화제 로서의 우수성을 시사 하였다. The strain producing bioemulsifier was isolated from soil samples. The isolated strain was identified as the genus Acinetobacter through its morphological, cultural and physiological characteristics. The highest emulsification activity and stability by Acinetobacter sp. BE-254 was observed after 5 days of cultivation in the culture medium containing n-hexadecane 4%, NaNO_3 0.2%, KH_2PO_4 0.01%, MgSO_4·7H_2O 0.01%, CaCl_2 0.01% and yeast extract 0.01%. The optimum pH and temperature for bioemulsifier production were pH 7.0 and 30℃, respectively. Furthermore the most of bioemulsifier was produced during the exponential growth phase, and this suggested that the bioemulsifier production was growth-associated. The bioemulsifier showed good emulsification activity on various emulsifying substrates such as hydrocarbons, edible oils, and petroeum fractions.

본 연구에서는 경부외 마취제로 사용되고 있는 S-bupivacaine을 SMB를 이용하여 R-bupivacaine으로부터 분리하였다. 단일칼럼을 이용한 실험을 통해서 비선형 흡착평형식과 실험식으로부터 물질전달계수를 얻었다. PIM을 이용하여 얻은 경쟁 Langmuir 흡착평형식에서의 매개변수 a는 R-bupibacaine은 6.20, S-bupivacaine은 8.79 매개변수 b는 각기 0.364, 0.922 ml/mg이었다. 이 매개변수들은 상용 모사기에 적용되어 두 키랄물질을 분리하기 위한 최적조업조건을 얻었고, 실험적으로 확인하기 위해서 Kromasil® CHI-TBB로 충진된 1×10cm 칼럼이 2-2-2-2 구성으로 된 SMB를 이용하여 결과적으로 racemic bupivacaine을 98% 이상 고순도로 분리하였다. In this work, S-bupivacaine with the pharmacological activity of epidural anaesthesia was separated from R-bupi-vacaine by SMB (simulated moving bed). Nonlinear isotherm was suggested from the single column experiment and the mass transfer coefficient was obtained from an empirical equation. The parameters of a in competitive Langmuir adsorption equation empirically determined by PIM (pulsed input method) for R and S-bupibacaine were 6.20, 8.79 respectively, while those of b were 0.364,0.922 ㎖/㎈, respectively. These equilibrium and kinetic parameters were used by a commercially available simulator to find the optimum operating condition for resolving the two racemic mixtures. It was experimentally confirmed that based on these experimental conditions, the separation of bupivacaine enantiornery was successfully performed with the purity of more than 98% by SMB composed of eight column (2-2-2-2, 1×10㎝) packed with Kromasil CHI-TBB.

The Asian Advisory Committee of the ILO, at its 13th Session(singapore, 1966), in outlining the concept of the Asian Manpower Plan, recommended the adoption of appropriate population policies to moderate population growth by means of family planning and drew attention in this regard to the role of workers' education and welfare services provided by employers. At the world level, the Governing Body of the ILO at its 173rd Session(Geneva, 1968)authorized ILO action within its fields for competence in support of appropriate national and international efforts to moderate population growth. The Asian Advisory Committee strongly recommended every asian countries to include certain aspects of popuation policy as part of labour policy and establish a separate sub-programme for the industrial sector within the national programme. An intensive programme of family planning and related measures in the organized sector should be considered a very desirable and feasible element in population strategy. There is ample justification for special attentior to the organized sector on account of its strategic and favorable siutation, even though the population of the industrial workers is not very large in the context of the total population in the country. Since the workers' families in the organized sector are to some extent already motivated for family planning and social services, the adoption of the small family norm, the spread of family planning practice and a significant reduction in fertility can be achieved resonably quickly in the case of this limited but key social group. The important points are the better socioeconomic conditions prevailing in the industrial areas leading to better acceptance of family planning, the rural link of industrial workers for propagation of the small family norm, better facilities for implementation and evaluation of the porgramme in the organized sector and finally the cooperation and enthusiasm for the programme of many employers as also of the trade unions and voluntary agencies. As we all know, however, during over 10-years' history of korean family planning activities, very few efforts has been given to the industrial workers. This survey was conducted for the purpose of finding out the family planning knowledge, attitude and practice among the industrial workers with a hope of being a help to the starting family planning activities in industry in Korea. 2537 workers who were working in 24 various industries in the area of Yongdungpo Industrial Zone were surveyed. Followings are results obtained in this study ; 1. General Characteristics of the Respondants. As to the age composition of the respondants, similarily to that of the total industrial workers, in Korea, they were relatively young; 65.7% of male workers and 89.3% of female workers were under 29 years of age. And as to the educational background, of the 2537 workers only 0.9% were non-schooling. Those who reported having no religion constituted 63.7% of the respondants, while Budhists, Protestants and Catholics were 13.3%, 10.9% and 3.7% respectively. 2. Time Period of Marrital Life and Number of Children of the Married Workers. 32.4% of married workers had been married for 2 to 5 years and 24.4% of married workers, 6 to 10 years. Average number of children were 2.3 persons, which increased as the age became older and the educational background rose higher. 3. Current Use of Contraceptives by Spouse. 46.4% of married workers or their spouse were currently using contraceptives. The largest proportion of them were using oral pill, followed by rhythm method, condom, and loop. Of the contraceptive users, 27.6% explained dissatisfaction on their currently using methods mostly because of side effect (27.6%), cost(24.4%) and inconvinience (22.8%). Among nonusers, 51.0% were willing to use contraceptive in the future. 4. Future Possibility of Contraceptive Use among Single Workers after Marriage. 79.9% of all single workers wanted to use contraceptives after marriage. The rate of futureusage of contraceptives was highest among non religious group (82.5%) and lowest among Catholics(66.1%). 5. Expected Age of Marriage of Single Workers. 47.0% of male single workers wanted to marry at the age of 30-34 and 46.6%, at the age of 25-29 while 64.6% of female single workers wanted to marry at the age of 25-29 and 30%, at the age of 20-24. 57.0% of both single workers wanted to marry at the age of 25-29. The higher the educational background, the higher was the expected age of marriage. 6. Number of Children that the Single Workers want to have After Marriage. Average number of children that the single workers wanted to have was 2.7. Male workers wanted to have 1.6 sons and 1.1 doughters while female workers wanted to have 1.5 sons and 1.2 doughters. Expected number of children decreased as their educational background became higher and present age became younger. 48.4% of Catholics wanted to have 3 children while 43.8% of protestants and 43.5% of nonreligious group wanted to have 2 children. 7. Knowledge of the Single Workers about the various Contraceptive Methods. It was found that the knowledge of the single workers about the contraceptive methods was generally low; 67.6% of single workes knew about orall pill and the proportions of single workers who knew about condom, loop, sterilization and rhythm method were 25.9%, 17.2% and 13.6% respectively. 8. Source of Information that the Single Workers want to learn Contraception. 64.6% of the single workers wanted to learn the contraception at hospital or health center. The higher the educational background the higher was the proportion of workers who wanted to learn it from newspaper or radio. Protestants were more interested in learning from lectures in industry than other religious groups were. 9. Priority of Contents Education if It will be given to the Single Workers in Industry. The largest proportion (49.2%) of all single workers wanted sex education would be put as ae first priority in the contents of education in industry, followed by general population issues(23.8%) and contraceptive technique (22.2%). This order was clearer among those whose educational backgrounds were higher than high school and among Catholics. 10. Usual Counselor of the Single Workers on their Sexual Problems. 55.2% of the single workers had been conferring their sexual problems with their friends and 34.3%, with their parents, 3.1%, with clergy. 3.9% of them had never been conferring with others. The higher the educational background and the older the age, the larger was the proportion of workers who had been conferring their problems with their parents. Catholics were conferring with clergy more frequently than other religious groups were.

Dental resin composites were introduced commercially in the mid-1960s for the restoration of anterior teeth. Since their advent, resin composites have undergone significant development, which continues to improve the longevity and application of resin composite restorations. Despite the development of new dentin-bonding agents, no system is currently available that completely withstands the formation of contraction gaps at the cementum/dentin-restoration junction, due to the unavoidable polymerization shrinkage of the resin composite during setting, therefore, a major aim of this study was to minimize or control the polymerization shrinkage of composites allowing flow of resin during setting reaction. A thermal dilatometer (DIL 402C, TASC 414/3A Controller, Netzche, Germany) was used to measure and compare conventional continuous cure and pulse cure polymerization shrinkage of seven light curing dental composites and three compomers. For conventional cure, restorative material were polymerized for 2 minutes using VIP (Bisco, U.S.A.) with 400 ㎽/㎠ intensity. After then, further polymerization was allowed for next 12 minutes that total 14 minutes of shrinkage was measured. For pulse cure, material was pre-polymerized irradiating light for 5 seconds with 200 ㎽/㎠ and post-ploymerized 3 minutes later with 400 ㎽/㎠ for 2 minutes. 9 minutes were allowed for further polymerization that total 14 minutes of shrinkage was measured. Polymerization shrinkage ranged from 3.758 ㎛/㎜ (SYC) to 6.897 ㎛/㎜ (P60) for conventional cure and 4.026 ㎛/㎜ (FLT) to 6.996 ㎛/㎜ (SRF) for pulse cure. The highest difference between the two methods was found at EAN (2.713 ㎛/㎜), followed by F20 and CRA which showed significant differences of 2.133, 1.274 ㎛/㎜ respectively (p<0.05). The least difference was found at SYC (0.489 ㎛/㎜). Universal resin composite group showed the highest polymerization shrinkage (6.514±0873 ㎛/㎜), and flowable composite showed the least shrinkage (4.139 ㎛/㎜). Packable composite showed 5.090±1.906 ㎛/㎜, and compomers showed 6.129±2.652 ㎛/㎜.
