Background : For cultivation of varieties of ginseng, the pure line selection method, which is to select the best among those cultivated in farms for pedigree breeding, replicated yield trials and regional adaptation trials before registering as a new variety, is widely used. Although there are 25 registered varieties of ginseng in Korea, the quality of ginseng is declining together with the amount of harvest being decreased by 15 - 20% due to the heat injuries and diseases from the warming & abnormal climate. Thus, the needs for development of disaster-resistant varieties with better chances of surviving through high temperature, salts and disease are increasing. Therefore, this study is to cultivate disaster-resistant varieties among those selected for their disaster tolerance and salt tolerance through regional adaptation trials. Methods and Results : As a result of examining the growth characteristics of the selected 2 - 5 year old varieties used in the study, among the 5-year old crops, Goryeo 4 and Eumseong 5 showed superior growth in both above and below aerial parts, and among the 4-year old crops, Eumseong 11 and Cheonryang showed superior growth while the growth in the below aerial parts were satisfactory in the order of Cheonryang > Eumseong 10 > Eumseong 11 > Eumseong 9. Among the 3-year old crops, the most superior growth in both above and below aerial parts was observed in Eumseong 14 with the weight of the below aerial part, root diameter and taproot length at 13.8 g, 11.8 ㎝ and 6.2 ㎝ respectively. Among the 2-year old crops, Eumseong 10 showed the most superior growth in both above and below aerial parts. Conclusion : Based on the above results, Goryeo 4 and Eumseong 5 among the 5-year old crops, Eumseong 11 among the 4-year old crops, Eumseong 14 among the 3-year old crops and Eumseon 10 among the 2-year old crops showed the most superior growth among the selected varieties. The growth characteristics of both above and below aerial parts in each year will continuously be monitored.

In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria gonorrhoeae(PPNG), we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by menas of the chromogenic cephalosporin method. In 1998, 93 strians of N. genorrhoeae were isolated, among which 60(64.5%) were PPNG. The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 64.5% in 1998.

Background Nowadays a lot of reseant is based on natural substances or materinals world wide since many kinds of side effects are accompanied by anti tumor chemotherapy. In Chinese medicine, Dioscorea bulbifera L is widely used to treat many kinds ofi cancer, but in Korea it is rarely used. Therefore, we need to scientifically identify anti tumor effects of Dioscorea bulbifera L.Objective: We aimed to identify anti tumor effects of Discorea bulbifera L on the stomach cancer cells through molecular biological methods.Materials & Methods: We used AGS, a stomach cancer cell from American Type Culture Collection We injected the boiled extrat of Dioscorea bulbifera L 5 ul(sample 1), 10u1(sample 2) to cultured media(ml) for 0,6,12,15,24 hours. We measured the killing effect on stomach cancer cells through Tryphan blue exclusion test and suppressive effect on viability of stomach cancer cells via MTT assay Results: Tryphan blue exclusion test showed that each test group killed more stomach cancer cells than the controlled group with a dosage-dependent, but not significantly. MTT assay showed that each test group had a more suppressive effect on viability of stomach cancer cells than the controlled group without a dosage-independent, but not significantly.The cell cycle analysis via flow cytometry showed that the test group extended cell cycle, and there was no peak in M phase, the number of subGl , GO, G1 phase cells increased a little, but not significantly.Conclusion : This experiment showed that Dioscorea bulbifera L. has an anti-tumor effect, but not significantly. This is in vitro experiment and basic experiment on Dioscorea bulbifera L. We hope more progressive researches on Dioscorea bulbifera L. will be conducted and its anit tumor will be more accurately identified.

The development and maintenance of a sound bond are essential requirements of concrete repair and replacement The bond property of a overlay to its substrate concrete during the lifetime is one of the most important performance requirements which should be quantified A standard or a verified bond strength measurement method is required at field for screening. selecting materials and quality control for overlay or repair materials. but no test method has been adopted as a standard. In this study. a concrete pull off bond strength measurement method for field application is proposed and evaluated. This study compares the splitting tensile test. slant shear test. nipple pipe direct tensile test. flexural adhesion test. briquette tensile test. jumbo nail pull-out test and core pull-off test with their test procedures. From these cornpanson and investigation. core pull-off test is selected as a main topic of this study because of it's suitability for in situ testing. simplicities in field application and clearness at interface boundary condition Thus. the proposed core pull off test is evaluated to be the most appropriate method for field application in a simple manner. The fracture surface and fracture mode could be easily determined by visual observation of failure surface of the field specimen. The core pull off test was found to be sensitive to surface condition and latex contents at latex modified concrete

안면 비대칭 환자의 수직 안모 유형과 이하두정 두부방사선 규격사진 계측치 및 표면 근전도의 상관성에 대한 연구

김성수,차봉근,이남기 대한치과교정학회 2006 대한치과교정학회지 Vol.36 No.3

안면 비대칭 환자의 진단분석에 이용할 수 있는 이하두정 두부방사선 규격사진과 표면 근전도 검사 자료는 통용화된 진단분석법 부재 등의 이유로 제한적으로 사용되고 있다. 그러나 여타 진단분석법과 비교할 때, 수직 안모 유형의 평가 등 차별적인 정보를 얻을 수 있어 이에 대한 연구가 필요하리라 보인다. 본 연구의 목적은 안면 비대칭을 보이는 60명을 대상으로 이하두정 두부방사선 규격사진 및 저작근의 표면 근전도를 측정하여 수직 안모 유형과의 연관성 및 안면 비대칭과의 연관성을 평가하고자 함이다. 이하두정 두부방사선 규격사진 계측치 중 radiographic corpus length는 비편위측이 큰 값을 보였고 (p < 0.001), 유의성은 없었으나 gonion to interspinosum axis는 편위측이 크고, gonion과 하악과두의 위치는 비편위측이 편위측에 비해 전방에 위치하였다 (p = 0.07). 안정시 편위측 전측두근의 근활성은 비편위측보다 높은 것으로 나타났다 (p < 0.01). 또한 최대 폐구 시 교근의 활성은 유의성이 없었으나 비편위측에 비해 편위측이 큰 값을 보였다 (p = 0.09). Facial index와 intercondylar axes angle은 양의 상관관계를 보였다 (p < 0.01). 최대 폐구 시 편위측 및 비편위측의 교근의 활성은 facial index와 양의 상관관계를 보였다 (p < 0.05). 이상의 결과를 통해 골격성 안면 비대칭을 보이는 환자에서 이하두정 두부방사선 규격사진과 표면 근전도 검사를 통해 비대칭 양상의 평가와 더불어 수직 안모 유형의 평가 또한 가능한 것으로 생각된다. Although the submentovertex radiograph and surface EMG are not often used due to the difficulty of interpretation, they are accepted as useful diagnostic and analytic aids for skeletal asymmetry. There have been reports which state that they were also useful for the evaluation of vertical skeletal relations. The purpose of this study was to evaluate the correlations between EMG data, measurements from submentovertex radiographs, facial types and facial asymmetry following examination of 60 asymmetric patients. The radiographic corpus length were greater in the nonaffected sides (p < 0.001), gonion to interspinosum axis were greater in the affected sides and the mandibular condyle and gonion were located more anteriorly in the non-affected sides than in the affected sides but not significant (p = 0.07). The activity of the anterior temporal muscle in rest position was higher in the affected sides than in the non-affected sides (p < 0.01). The activity of the masseter muscle at maximum clenching was found to be nonsignificant but it was higher in the affected sides than in the non-affected sides (p = 0.09). There was positive correlation between facial index and the intercondylar axes angle (p < 0.01). There was positive correlation between masseter muscle activity in maximum occlusion and facial index in the affected and non-affected sides (p < 0.05). The results demonstrate that the submentovertex radiograph and EMG can provide useful information for the evaluation of horizontal and vertical skeletal relations.
