The purpose of this study was to consider the features of teaching behavior and each teaching behavior was compared and analysed with group cohesion in Korea Ssireum. The researcher worked with 30 high school teams, 15 college teams, 12 ordinary teams and 4 falk teams belonging to Korea Ssireum Association and the Korea Ssireum Federation from February, 2002. The researcher made a radome choice of 10 players each team and worked with a total of 570 players with questionnaries. The researcher conducted a frequency analysis, a correlation analysis and regression analysis with SPSS 10.0 and the significant level of all the hypothesis tests stands at a=.05. The conclusions of this study were as follows: First, there was a high correlation for the all subordinate variables in teaching behavior of leaders. The survey showed that there was a positive influence at a level of 1 percent. And there was no correlation between authority behavior and group cohesion with a negative influence at a level of 1 percent. Second, there were influences both training behavior and compensation behavior for player relationship, life satisfaction of player was affected in training behavior and democratic behavior with a positive influence at a level of 5 percent. And life frustration of player was affected in training behavior, social support behavior and compensation behavior, specially training behavior and compensation behavior were affected with a positive influence at a level of 5 percent.

The purpose of this retrospective study was to radiographically evaluate the apical sealing efficacy of cold-burnished gutta-percha as a root-end filling material. Radiographs of 41 teeth from 37 patients were used, with the recall period ranging from a minimum of 1 yr to a maximum of 6.7 yr. Radiographic findings were classified into one of three groups: 1. complete healing; 2, incomplete healing(scar tissue); 3, unsatisfactory healing. The results were as follows: 1. There was no significant difference in frequency of operation between male and female. 2. The teeth most frequently operated on were the maxillary central incisors (39%). The Maxillary lateral incisors were the second largest group in frequency at 34%. 3. Patients between 21 and 40 yr of age formed the single largest group. 4. Complete healing was found in 58.5% of the recall cases, while incomplete and unsatisfactory healing occurred in 34.2% and 7.3% of the cases, respectively. Based on this retrospective study, We concluded that 38 of 41 cases(92.7%) were considered to be successful and 3 cases (7.3%) were determined to be failures.

LHR(Landfill Site Hazard Ranking Model)was developed for assessing the relative hazard of landfill sites by using the method of value-structured approach. LHR consists of combining a multiattribute decision-making method with a qualitative risk assessment approach. AHP(Analytic Hierarchy Process)based on the pairwise comparison method was applied to determine weights of landfill site factors related. To determine the relative hazard of landfill sites evaluated, hydrogeological factors, waste characteristics factors and recptors factors were evaluated by LHR. LHR can help decision-makers prioritization of remediation of landfill sites through the relatively convenient and concise evaluation metl10d of landfill site features related. LHR focuses mainly on pathways of groundwater and surfacewater for evaluating landfill hazard to receptors including humans. To validiate the applicability of LHR, Nanjido Landfill site, Metropolitan Landfill site, and Hwasung Landfill site were evalulated. LHR scores of the above-mentioned landfills were 55, 19, and 7 respectively.
Mineral Trioxide Aggregate(MTA)의 치근단 역충전효과에 대한 임상적 연구
홍찬의,홍한표,조용범 단국대학교 치의학연구소 1994 논문집 Vol.6 No.1
Although numerous materials have been recommended as root end filling material, so far no material has been found to satisfy all of the requirements of an ideal material. An experimental material, mineral trioxide aggregate(MTA), has been recently developed to seal off all pathways of communication between the root canal system and the external surface of the tooth. This material has been used to seal the root end cavities in extracted teeth and similar preparations in beagle dogs and shown very promising results. In this clinical study, 5 anterior teeth from three patients were used to clinically and radiographically evaluate the efficacy of MTA as a root end filling material on a short-term basis. After removing the apical 2 to 3 ㎜ of the roots, The root end cavities were prepared and filled with MTA. The results were as follows: 1. All the cases demonstrated excellent healing radiographically and absence of clinical signs and symptoms. 2. According to the results, it appeared that MTA had a good sealing ability and biocompatibility. 3. MTA showed very promising results as a root end filling material, but Long-term clinical retrospective studies of many cases are recommended to get the most valid evaluations.

Background: Pneumocystis carinii (PC) is a opportunistic pathogen causing serious pneumonia (Pneumocystis carinii pneumonia : PCP) in immunosuppressed patients including AIDS. Laboratory diagnosis of PCP is dependent on microscopic demonstration of the PC by using cytochemical staining or by immunocytochemical staining with monoclonal antibodies. However, these staining methods are not highly sensitive. The development of the polymerase chain reaction (PCR) has made it possible to detect very small numbers of pathogens in clinical specimens. To establish the usefulness of PCR for detection of PC DNA, We performed PCR as a pilot study. Methods: PCP was induced on Spraque-Dawley rats with prednisolone 5mg IM twice a week. Bronchial lavages, impression smears, and permanent sections were performed from the 3rd week to 7th week of cortisonized rats. PC DNA was extracted with bead beater / 10% CTAB method. Results: Impression smears showed PC cyst after the 4th week (100%, 28/28 rats), and permanent sections showed 27/28 rats. Control rats showed some PC cysts (2/7). PCR result was positive only one case among the 6th week rats (1/7), But positive 6 cases at the 7th week rats, (6/7). Among control rats. 2 cases were positive (2/7). ??This data is a pilot study for the PC DNA detection using a PCR. PCP were successfully cortisonized rats. If adequate bronchial washing technique will be used, PCR can be a sensitive for PC DNA detection.

The purpose of this study was evaluate immunohistochemical observation to epidermal growth factor of the effect of duct ligation of mouse submandibular gland. Fifty two mice were aging 3 months old, devided into experimental group(36 mice) and control group (16 mice). Under general anesthesia, 36 animals were ligated in left side duct of submandibular gland. Experimental animals were sacrificed consecutively on 1st, 6th, 12th hours and 1st, 2nd, 3rd, 5th, 7th, 14th day after duct ligation. These specimens fixed with formalin and sectioned in paraffin. Subsequently were stained with H-E and immunohistochemistry to observe epidermal growth factor. The results were as follows ; 1. After duct ligation, the acinar cells were atrophied and disappeared and granular convoluted tubule cells in which cytoplasm atrophied and granules reduced, degenerated duct-like structure. 2. With the time lapse, epidermal growth factor in cytoplasm of granular convoluted tubule cells reduced with change of features of granular convoluted tubule. 3. From 7th day after duct ligation, there are suggested that duct-like structure were originated from granular convoluted tubule and these were regressive changes by secretory disturbance.
