Purpose: This study examined the clinical success rate of Mg titanate implants (M Implant system, Shinhung, Korea), which employ a Mg coating method, by evaluating the marginal bone loss and implant stability using radiographs and Osstell, over a 1 year. Materials and methods: The locations of the implants placement were divided into 4 areas; the maxillary and mandibular premolars and molars. In the maxilla, 8 and 9 implants were inserted in the premolar and molar areas, respectively. In the mandible, 11 and 51 implants were inserted in the premolar and molar areas. Marginal bone loss and ISQ of all implants (79) were measured after insertion, mounting the prosthetic appliance, and 1, 3, 6, and 12 months after loading. The marginal bone loss was measured from the radiograph using XCP bite, which was customized, and the implant stability measured using Osstell. Fisher's exact test (α=.05) was used to compare the success rates of each region. Results: The mean marginal bone loss for the upper and lower jaws were 1.537 mm and 1.172 mm. The mobility showed a non-significant reduction or increase according with time. The success rates were accounted for 94.12% and 98.39% in the upper and lower jaws; the premolars and molars were accounted for 100% and 96.67%. The two cases of early failure resulted from failure of primary stability during implant insertion. The late failures were not observed for 1 year after adding a loading to the implants. Conclusion: The Mg titanate implant showed good primary stability and good clinical results in both healing and function. 연구 목적: 부분 무치악 환자에서 Mg titanate implant (M Implant system, Shinhung, Korea)의 보철후 1년간의 방사선사진을 이용한 변연골 흡수량과 Osstell을 이용한 임플란트 안정성 평가 결과를 분석하여 임상적인 성공률에 대해 알아보고자 한다. 연구 재료 및 방법: 38명의 환자에 79개의 임플란트를 식립하여 보철 후 1년 동안 변연골 흡수량, 임플란트의 동요도, 임플란트 식립 위치에 따른 분포 및 성공률, 보철 전후에 따른 성공률을 분석했다. 결과: 변연골의 흡수량은 보철물 장착 후 1년간의 평가에서 상악에서는 평균 1.537 mm, 하악에서는 평균 1.172 mm의 변연골 흡수가 관찰되었으며, 전체적인 상하악의 평균 변연골 흡수량은 1.255 mm로 관찰되었다. 수술 후 시간이 경과함에 따라 ISQ값은 미약하게 감소하였다가 증가하는 경향을 보였으나, 상악과 하악 모두에서 식립 당일 이후 예비 인상일, 최종 보철물의 장착일과 주기적인 평가 기간 동안 ISQ값의 큰 증가나 감소를 나타내지는 않았다. 성공률은 상악에서의 94.12%였고, 하악에서의 98.39%였다. 결론: 본 실험의 결과로 미루어 Mg titanate implant는 임상적으로 양호한 결과를 보여주었다.

人間主義的 學習理論의 適用과 評價에 關한 一考察(Ⅱ)

朴井秀,安福禮 대구교육대학교 1985 論文集 Vol.21 No.-

1. Suggestions for applying the humanistic view in the classroom 1) Try to remain aware of the extent to which you direct and control learning. Whenever possible, permit and encourage students to make choices and to manage their own learning. 2) Establish a warm, positive, acceptant atmosphere. Do your best to communicate the felling that you believe every student in the class can learn and that you want them to learn. 3) when it seems appropriate, function as a facilitator, encourager, helper, and assister. Before attempting to function as a collegeue or friend, think about possible complications. 4) It you feel comfortable doing it, occasionally show that you are a "real person" by telling students how you feel. When you express anger, however, comment on the situation, not on the personality traits of your students. 5) It you do not have trong positive feeling about yourself and how you-function as a teacher, consider participating in individual or group counseling sessions, and also work at improving your skills as an instructor. 6) Do your best to help your students develop positive feelings about themselves. Empathize with them, and show you are sensitive to their feelings. 7) It appropriate, schedule occasional periods during which students are encouraged to examine their emotions. 8) If appropriate, schedule occasional period during which students are encouraged to become more sensitive to the feelings of others. 9) If appropriate, schedule occasionally periods when students are encouraged to express themselves through movement, physical contact, and creative dramatics. 10) If appropriate, ask students to participate in role playing, psychodrama, or simulation games. 11) Make systematic use of values clarification strategies. (a) Call attention to the process of values development. (b) Select and use strategies that cover all seven steps in the process of values acquisition and call attention to ways an exercise illustrates one or more aspects of the sequence. (c) Use long-term strategies in class, and urge students to continue to use them on their own. (d) Look for ways to introduce values clarification strategies into lesson plants. 12) Use the Taxonomy of Educational Objectives: Affective Domain to identify specific goals of humanistic education. 13) Do your best to provide learning experiences that will lead to the development of the habits and attitudes you want to foster. 14) Make use of object lesson. When illustrative incidents occur in the course of events, take advantage of them. 15) Set a good example. 16) Be aware id your students' level of moral development, and encourage understanding of subtle aspects of morality by presenting "moral dilemmas", 2. Criticisms of humanistic education 1) Humanistic view based on vague propositions. 2) Achievements of Summerhill students unimpressive. 3) Summerhill graduates not atypically creative. 4) Graduates wanted own children to attend Summerhill only briefly. 5) Some humanistic educators affect holier-than-thou attitude. 6) Values clarification may not have a significant impact. 7) Humanists offer testimonials, not evidence, to justify lavish claims. 8) Some humanistic technique resemble compulsory psychotherapy conducted by "amateurs", 9) Impossible to maintain close personal relationships with pupils.

뇌졸중, 파킨슨 병, 척수신경손상 등으로 연하관련 근육들의 협동운동장애가 발생한 환자에서 흡인성 폐렴이 반복되거나 경장영양이 곤란하게 된다. 이러한 경우에 경피내시경하 위루술(percutaneous endoscopic gastrostomy)은 이들 환자의 생명을 유지하는데 매우 중요한 역할을 해 왔다. 위궤양 혹은 위암 등으로 위절제술을 받은 환자에서 위루술 대신에 부득이 경피내시경하 공장루술(direct percutanous endosopic jujunostomy)이 시행되었던 경우는 국내외에 몇 례의 보고가 있다. 본 증례는 과거 후두암 때문에 후두부식도절제술 후 결장 끼어듬(colon interposition) 수술을 받은 65세 남자 환자로 최근 좌측중대뇌동맥 경색으로 연하장애가 발생되었다. 저자들은 이 환자에게 지속적인 영양공급을 위하여 경피내시경하 결장루술을 합병증 없이 시행하였기에 보고하는 바이다. Dysphagia is a loss of coordination in the swallowing musles. It has occurred in patients with cerebrovascualr accident, head injury, Parkinson's disease or cervical cord injury. Dysphagia results in nutritional deficiency or repeated aspiration pneumonia. Percutaneous endoscopic gastrostomy have helped these patients to maintain healthy and save lives. Several cases of direct percutaneous endoscopic jejunostomy have been reported in patients who received gastric resection for a stomach cancer or peptic ulcer hemorrhage. A 65-year-old male patient, who was suffering from dysphagia, whose symptom was caused by left middle cerebral infarction. He was referred to the division of gastroenterology for the provision of permanent enteral feeding. His esophagus had been resected and replaced with a part of colon because of laryngeal cancer 5 years ago. We could not approach the stomach because the angle of anastomosis was acute and the colonic graft was long. We performed direct percutaneous endoscopic colostomy without any complications. Herein, we report on this successful case.

The common strategy of speed control of single-phase induction motors depends mainly upon controlling the applied voltage on the motor. Changing the applied voltage on the motor can be effected by several techniques. Some on these techniques auto-transformers or adding extra winding, as required, to either the main or auxiliary winding. The other approaches use power electronic devise such as TRIAC. Each one of these schemes has and demerits. Single-phase induction motors are always small and are seldom built in sizes over fractional horsepower ratings, In view of this, they are deprived from controlling their speed by expensive drives which employ frequency control; a matter which offers a wide range of speed control. However, if the input supply frequency to a single-phase induction motor is controlled by a single controlled forced commutated device. Certainly, the event will be a remarkable achievement. This approach is the essence of the present paper. The paper presents a new drive for single-phase induction motor. This drive bridge rectifier connected with the stator in a non-conventional fashion. The speed of the single-phase induction motor is controlled by controlling the chopping frequency of the chopper switch. The attractive feature of the drive is that it effects doth frequency and do chopping simultaneously. The drive performance has received both theoretical and experimental investigation.

Tofisopam is a new type of tranquilizer valuable for the relief of anxiety and tension in a wide range of emotional disorders. Tofisopam has the therapeutic characteristics of a minor tranquilzer and a mild stimulatory effect. The purpose of the present study was to evaluate the bioequivalence of two tofisopam tablets, Grandaxin^TM (Hwan In Pharmaceutical Co., Ltd.) and Tofim^TM (Kyung Dong Pharmaceutical Co., Ltd.), according to the guidelines of Korea Food and Drug Administration (KFDA). Eighteen normal male volunteers, 23.11±2.83 years in age and 65.43±7.64㎏ in body weight, were divided into two groups and a randomized 2 x 2 cross-over study was employed. After one tablet containing 50㎎ of tofisopam was orally administered, blood was taken at predetermined time intervals and the concentrations of tofisopam in serum were determined using HPLC method with UV detector. The pharmacokinetic parameters such as AUC_t, C_max and T_max were calculated and ANOVA test was utilized for the statistical analysis of the parameters. The results showed that the differences in AUC_t, C_max and T_max between two tablets based on the Grandaxin^TM were -5.59%, 2.22% and -13.18%, respectively. Minimum detectable differences (Δ) at α=0.10 and 1-β=0.8 were less than 20% (e.g., 14.95% and 19.34% for AUC_t and C_max, respectively). The powers (1-β) at α=0.10, Δ=0.2 for AUC_t and C_max were 95.21% and 81.93%, respectively. The 90% confidence intervals were within ±20% (e.g., -15.64∼4.45 and -10.77∼-15.21 for AUC_t, and C_max, respectively). Two parameters met the criteria of KFDA for bioequivalence, indicating that Tofim^TM tablet is bioequivalent to Grandaxin^TM tablet.
