Background: Metabolic syndrome is caused by interplay between genetic and many environmental factors. Some behaviors or lifestyle patterns including physical activity, cigarette smoking, and diet, particularly carbohydrate and fat intake are associated with the metabolic syndrome. The objective of this study was to identify the relationship between metabolic syndrome and some lifesyle behaviors. Methods: A total of 635 medical check-up examinees who were examined in Kosin University Gospel Hospital from December, 2004 to July, 2005 were enrolled in this study. The height, weight, waist circumference, and systolic and diastolic blood pressure of the subjects were examined and on concentrations of fasting blood glucose, total cholesterol, HDL cholesterol, LDL cholesterol, and triglyceride in peripheral venous blood were measured. The metabolic syndrome was defined as the presence of three or more of the following; waist circumference men ≥90 cm, women ≥80 cm, blood pressure ≥130/85 mmHg, fasting glucose ≥110 mg/dL, HDL cholesterol, men <40 mg/dL, women <50 mg/dL, and triglyceride ≥150 mg/dL. The blood pessure, fasting glucose, HDL cholesterol, triglyceride were evaluated by using the criteria of NECP ATP Ⅲ and waist circumference was assessed by using the criteria of WHO Asia-Western Pacific. Self-administered questionnare was conducted on smoking, alcohol drinking, educational level, exercise, and dietary practices. Results: The prevalence of the metabolic syndrome was 37.5%. High fat intake was significantly associated with an increased risk of having the metabolic syndrome. In women, low educational level and high carbohydrate intake were associated with an increased risk of having the metabolic syndrome. High fat intake was significantly associated with an increased risk of having the metabolic syndrome in body mass index ≥25/0 kg/m2 or 50-59 years group. Conclusion: Low educational level, high fat and high carbohydrate intake were significantly associated with an increased risk of having the metabolic syndrome.

The purpose of this study is to investigate the differences of root formation by using different three materials histopathologically. 11 beagle dogs about 6 months old and 11.2kg by mean weight were used for root canal filling, a total of 94 root canals from 54 mandibular premolars with immature roots. Pulp tissues were exprirpated and root canals were left open for 2 weeks before debridement,and filled with Ca(OH)2-CMCP paste for control group and Vitapex, A.R.S.(Apatite Root Sealer type Ⅱ) for experimental groups. The teeth were then observed for the healing of periapical tissues, types of apical closure and hard tissue formation at 30,90,180 days after the treatment histopathologically. The results were as follows: 1.In final evaluation, it revealed 70% as good, 20% as fair and 10% as poor in control group, 74% as good, 20% as fair and 6% as poor in Vitapex group, and 36% as good, 45% as fair and 19% as poor in A. R. S. group. 2.In the status of apical closure, 80% of the control group, 91% of the Vitapex group and 73% of the A. R. S. group were observed for complete and incomplete apical closure. 3.Of the 5 types of apical closure, closure at apcial foramen type was most common(mean 52%) in all groups. And extracanal closure types were more common in control group compaired with experimental groups. Root growth types were not observed. 4.In X-ray evaluations, proper canal filling cases were more evaluated as good and fair,and poor cases were not observed in experimental groups. In the treatment of immature permanent teeth with infected root canals, Vitapex produced better results than Ca(OH)2-CMCP paste. Cases evaluated as poor for A. R. S. were more common and so more longer period observation is needed.

The main purpose of this study is to clarify the directions of social studies education in information-age. Here, the following three questions will be asked. First, what are the socio-cultural qualities of information society? Second, are there any possibilities and limitations in the educational uses of tele-communication technology? Third, what are the directions of social studies education in information society? The results are as follows: (1) Coming future will be the information society/knowledge society as technical revolution proceeds and the global village will be diversified and opend with each other. The people will take part in the conduct of state affairs more directly. Information-concentration enables people to develop more rational decison-making. The synergy of tele-communication skills, new media and post-modern culture puts techno-culture in a higher position. But the information society will also show us negative aspects. Students should to have comprehensive perspectives to the complicated issues. (2) The change of educational environments in the information society consists of practical uses of tele-communication skills, computer, multimedia, virtual reality, and internet. These transform traditional education into on-line education, home-learning network, cyber-school, tele-library, etc.. But the limitations of educational uses of tele-communication technology are especially interpersonal and intrapersonal problems. It is by man that education is realized. (3) The main purpose of social studies for coming future society is to increase an ability for students to adapt to the newly emerged environments. Thus, the new directions of social studies will represent the interdisciplinary characteristic which helps when they confront with the social problems caused by the socio-structural changes. In order to solve these problems, the directions of social studies education in information society are followings. First, we need to help students to learn how to be qualified global citizen who understands and efficiently adjusts to the global community and information society. Second, social studies education has to lay stress on overcoming the dysfunctions of information society. Third, we need to take political-socialization education of information in order to defend democracy against the political perils of new media. Finally, social studies education should emphasize information ethics for human society. As a whole, for the proper adjustment to the information society, we have to successfully socialize the future generation as responsible and able citizens through the social studies education.

O/W 에멀젼의 입자크기 및 상거동에 미치는 다양한 전상유화법의 효과

김철훈,박재길,허정림,유영태,박태욱,이치규 ( Cheol Hun Kim,Jae Kiel Park,Jung Rim Haw,Young Tai Yoo,Tae Wook Park,Chi Giu Lee ) 한국공업화학회 1995 공업화학 Vol.6 No.4

유화제는 polyoxyethylene(20)sorbitan monostearate와 sorbitan sesquioleate를 혼합 사용하고, 오일상으로는 liquid paraffin을 원료로 사용하여 다양한 전상유화 법으로 O/W 에멀젼을 제조하였다. 전상유화공정중에 오일상에 첨가되는 적량의 물은 가용화 되거나 유화되어 W/O 에멀젼으로 된다. 이 W/O 에멀젼은 분산상의 부피변화나(catastrophic inversion) 유화제의 오일과 물에 대한 친화도변화(transitional inversion)에 의해 O/W 에멀젼으로 전환된다. Direct 유화방법을 채택한 2단계 전상유화법의 공정에서는 잠정적인 (W/O)/W 이중에멀젼이 형성되었다 : 최종에멀젼이 W/O→(W/O)/W→O/W의 전환 단계를 거쳐서 생성되었다. 이 전환에서는 catastrophic inversion이 일어났다. 1단계 및 3단계 전상유화법은 W/O에서 pseudomicroemulsion gel상을 거쳐서 미세하고 균일한 O/W에멀젼입자가 얻어졌다 : W/O→pseudomicroem ulsion gel상→O/W. 이 전환에서는 연속상의 일정농도(5∼17wt%) 내에서 transitional inversion이 일어남을 알 수 있었고, 3단계 전상유화법이 2단계 전상유화법보다 더 미세하고 균일한 입자를 갖는 높은 점도의 에멀젼을 생성하였다. 본 연구에서 가장 미세하고 안정한 에멀젼입자가 형성되는 혼합유화제의 HLB 영역은 10.0∼10.8이었으며, 아울러 이 영역에서 오일상에 첨가되어 가용화되는 물의 양 또한 가장 많게 나타났다. O/W emulsions were prepared with the various phase inversion emulsification methods. The emulsifiers used were the polyoxyethylene(20)sorbitan monostearate and sorbitan sesquioleate, and the oil used was a liquid paraffin(dispersed phase). A portion of aqueous phase added during the phase inversion emulsification process is solubilized or emulsified into the oil phase to form a W/O primary emulsion. This primary emulsion eventually inverts to form an O/W final emulsion either by changing the dispersed phase volume(a catastrophic inversion) or by changing the surfactant`s affinity for the oil and water phases(a transitional inversion). A short-lived double emulsions of (W/O)/W type were formed in the process of the two-step phase inversion which adopted the direct emulsification method : O/W final emulsion was formed as follows, i.e., W/O→(W/O)/W double emulsion→O/W emulsion. Catastropic inversion occured in the two-step phase inversion emulsification method. In one-step phase inversion emulsification and three-step phase inversion emulsification, fine and homogeneous O/W emulsions were formed as follows, i.e., W/O→pseudomicroemulsion gel phase→O/W. In this method the transitional inversion occurred within constant concentration(5-17wt. %) of contineous phase. The more fine, homogeneous and viscous emulsion was prepared with the three-step phase inversion emulsification method than that of emulsions prepared with the two-step phase inversion emulsification method. The finest and most stable droplets were formed in 10.0∼10.8 HLB region of mixed surfactants and this HLB region had maximum amount of solubilizing water.

성장기 외상으로 인한 상악전치부 결손 환자 악교정수술 및 임플란트 수복 케이스

김철훈,김무성,장국원,김복주,황희성,전영미,김도희 대한통합치과학회 2018 대한통합치과학회지 Vol.7 No.2

Implant placement of the maxillary anterior teeth should consider all of the esthetics and functions. In patients with maxillary deficiency, maxillary anterior implants can not be placed in an aesthetic position, and the occlusal forces acting are disadvantageous. In this case, implant placement should be planned after improving the intercourse relationship by orthognathic surgery. Therefore, in order to obtain good results, orthodontist, prosthodontist, oral and maxillofacial surgeon interdisciplinary approach and co-operation is important. This case report describes a case of maxillary anterior implants that was accompanied by orthognathic surgery and block bone graft in a patient who had lost maxillary anterior teeth due to trauma. 상악전치부의 임플란트는 심미적 요소, 기능적 요소를 고려해야한다. 상악 저성장이 있는 환자인 경우, 상악 전치부 임플란트는 심미적으로 배치할 수 없고, 교합력은 임플란트에 불리하게 작용한다. 이 경우 악교정수술을 통하여 악간관계를 개선한 후에 임플란트를 식립 해야한다. 이때 좋은 결과를 얻기 위해서는 교정의, 보철의, 구강악안면외과의 간의 협력이 중요하다. 이 증례보고에서는 상악전치부의 외상으로 인한 상실 환자에서 악교정 수술과 골이식술을 동반한 상악전치부 임플란트를 성공적으로 치료하였기에 이에 대하여 보고하고자 한다.

We clinically evaluated 182 cases of the ventricular septal defect that we experienced at the Department of Thoracic and Cardiovascular Surgery, Maryknoll Hospital from March 1986 through June 1990. Of the 182 cases, 95 patients were male and 87 patients were female. Their age distribution ranged from 8 month to 37 years and their mean age was 8.1 years. The most common chief complaint was frequent upper respiratory infection. Among them, 46 patients had associated cardiac anomalies, which were subdivided as follow; 9 cases of patent foramen ovale, 8 cases of infundibular stenosis, 6 cases of pulmonary valvular stenosis, 4 cases of left superior vena cava, and etc. The most common preoperative abnormal EKG finding was left ventricular hypertrophy in 22 cases. Ninety-three patients[51.1%] underwent simple closure of the VSD and the rest[48.0%] underwent patch closure. In anatomical classification by Kirklin type I constituted 24.2%; type II, 74.8%, type III, 0.7%, and the mixed type of type I and II, 0.5%, The important postoperative EKG changes were noted in 38 cases[20.9%], 18 cases of which were incomplete right bundle branch block. Thirty-three patients[18.1%] developed minor and major complications, and five patients died, overall operative mortality being 2.7%.
