Present studies were carried out to produce tetraploid plants by colchicine treatment using seeds, seedlings and shoot tips of Codonopsis lanceolata. Three tetraploid plants of C. lanceolata were produced from seeds which absorbed 0.1 % colchicine solution for 12 hours, and 0.5% colchicine solution for 1 and 6 hours from seedlings, respectively. But tetraploid was not produced from shoot tips treated by colchicine solution. Compared to diploid, tetraploid plants had larger stomata, but less number of stomata. Fresh weight of tetraploid plants was 1.4∼3.6 times heavier than diploid plants.

Present studies were carried out to produce tetraploid plants by colchicine treatment using seeds, seedlings and shoot tips of Platycodon grandiflorum in Campanulaceae. The most successful colchicine treatment for tetraploid production in P. grandiflorum was soaking treatment using 0.01 and 0.5% colchicine solution for 1 hour and 12 hours, respectively. Morphological characteristics of both diploid and tetraploid were similar, but tetraploid plants had more leaves. Compared to diploid, tetraploid had the larger stomata, but less number of stomata. Fresh weight of tetraploids was 20∼40% heavier than that of diploid.

이 연구에서는 체육․무도 관련학과 학생들을 대상으로 심층면접을 실시하여 이들의 대학생활에 대한 전반적인 문제점을 심층적으로 규명하는데 목적이 있다. 이러한 목적 달성을 위해서 전라남도 D대학교 체육관련 학과 학생들을 대상으로 비확률 표집방법 중 하나인 유목적 표집(purposeful sampling)에 의해 2학년부터 4학년까지 각 학년별 4명씩 총 12명으로 선정하였는데 다음과 같은 결론을 얻었다. 첫째, 체육․무도 관련학과 학생들의 대학생활에는 선․후배 간 체벌문화가 현재까지도 잠재되어 있음을 알 수 있었다. 이에 학생들은 선배들의 올바른 역할과 선․후배 간의 단합과 화합을 위한 매개체 요인이 필요하다는 의견을 보였다. 둘째, 체육․무도 관련학과와 같은 상․하 관계가 뚜렷한 집단에서는 선․후배간의 의사소통이 더욱 필요하지만 원활히 이루어지지 않는 것으로 나타났다. 또한 원활한 의사소통을 위해 다양한 개선을 요구하는 것으로 나타났다. 셋째, 체육․무도 관련학과 학생들은 대학생활에서 수업관련 문제점에 대해 가장 큰 비중을 두고 있었고 개선에 대한 욕구를 보였다. 특히 체육․무도 관련학과 전공수업에서는 무엇보다도 교수의 지도능력과 현실성 있는 교과과정 개설을 원하는 것으로 나타났다. 넷째, 체육관련 전공자들은 보편적으로 타 전공자들에 비해 취업의 기회 및 관련분야가 상대적으로 적을 수도 있다. 이러한 사회현실은 이들로 하여금 심리적인 불안을 갖게 하였으며 체육관련학과를 선택한 자체에 대한 불만족이기 보다는 체육․무도 관련 전공을 이수하고 나와서 안정적인 직장으로 연결되지 못하는 사회 제반적 여건에 대한 문제점을 보였다. 따라서 체육․무도 관련학과 학생들은 취업관심분야에 대한 업무능력․관련지식 등의 자질과 조건을 갖추기 위해 큰 관심을 가지고 있다. 취업정보 및 자격증 취득 등 취업을 위한 사전준비도 철저히 하고 있는 것으로 나타났다.

Uterus didelphys with unilateral obstructed hemivagina and ipsilateral renal agenesis usually presents after menarch with progressive abdominal pain during menses secondary to hematocolpos, and indeed a very rare congenital anomaly due to Mullerian duct malformation. An accurate and prompt diagnosis is of importance to permit treatment and to assure the future fertility of the patient. Pelvic ultrasound, physical examination and pelvic MRI established a diagnosis of hematometracolpos secondary to uterus didelphys with unilateral imperforate hemivagina. An incision in the vaginal septum allowed drainage of the hematocolpos, providing relief of the patients symptoms. We report two case of uterus didelphys with obstructed hemivagina with brief review of the literature.

김의한,최득린,정태은 순천향대학교 1993 논문집 Vol.16 No.2

A close relationship between Campylobactor Pylori and gastric disease was reemphasized by many authors. Campylobactor was mainly observed in the antrum of the gastric mucosa, and considered as a cause of gastric ulcer following to gastritis or intestinal metaplasia. This study was carried out to observe the incidence of C.Pylori in the gastric carcinoma diagnosed by endoscopic biopsy. The following results were obtained. 1. Campylobactor pylori was identified in 61 cases(68.5%) of gastric carcinoma among 89 cases of gastric carcinoma. 2. C.Pylori was identified in 35 cases of carcinoma with intestinal metaplasia and 26 cases of that without intestinal metaplasia, indicating no difference between two groups. 3. C.Pylori was equally identified in well differentiated, moderately differentiated and poorly differentiated carcinoma. 4. C.Pylori was more frequently identified in carcinoma of antrum and pylori than that of body. The above result indicate that C.pylori may play a part of roll for the carcinogenesis of the gastric carcinoma following gastritis intestinal metaplasia and gastric ulcer

W-polycide(??/n+poly-Si)구조로 poly-Si막과 ?? 막 두께를 변화시켜 LPCVD를 이용하여 증착하고 온도를 달리하여 열처리하였으며 이러한 텅스텐 폴리사이드특성에 poly-Si막과 ??막 두께, 열처리 온도가 미치는 영향을 조사하였다. ??막 두께가 증가함에 따라 면저항은 감소하고 스트레스는 증가하였으며 reflectance는 거의 일정하였다. poly-Si막 두께증가에 따라 스트레스는 다소 증가하였으나 면저항과 reflectance는 일정하였고 열처리 온도 증가에 따라서는 면저항과 reflectance는 감소하였고 스트레스는 증가하였다. 또한 조성(Si/W)비의 변화를 관찰하였다. Poly-Si and ?? films in polycide(??/n+poly-Si) structure were deposited by LPCVD to changed thickness, and then were annealed at various temperatures. The effect of poly-Si and ?? film thickness and annealing temperature on the W-polycide properties was investigated. With increasing ?? film thickness, it has been observed that sheet resistance decreases, stress increases, and reflectance in constant. It has also been observed that as poly-Si film thickness increases, stress increases a little bit, while sheet resistance and reflectance are constant. As the annealing temperature gets higher, the decrease in sheet resistance and reflectance, and the increase in stress have been observed. Also, the variation of composition(Si/W) ratio is examined.

We used the passive diffusion samplers that are known to be very useful to measure the concentration of air pollutants with respect to the spatial distributions. In this study, we estimated the badge type passive sampler which is evaluation of accuracy and precision and badge type passive sampler is used for the measurement of So2 and No2 in pohang, Kunsan, Daejeon industral complex monthly. Concentration and spatial distribution survey are presented during 1 years. For So2 and No2 passive sampler, we made additional two blank samplers for each compound with the passive samplers for the actual measurement. The results of blank test shows that No2 is 0.29ppb, So2 is 0.55ppb on basis of the month. Using the results measured at the same places as TMS (telemetering system) sites, the accuracy of the passive sampler could be checked. The measurement data with passive sampler was time weighted average concentration for a month. So, it might be difficult to compare two data directly. Althought the correlation between the results of passive sampler and TMS data were not appeared so high, the applicability of passive sampler would be acceptable considering that these data were produced in uncontrolled experiment environment. Monthly variations of average So2 concetration in three industrial complex areas was compared. The average So2 concentration in Pohang and Kunsan area was appeared to be higher than Daejeon area because Pohang and Kunsan area is much bigger than Daejeon area in the magnitude of industrial complex. Also Pohang area was apperad to be higer than Kunsan area because the measurement data in Pohang area included the data inside the factory's lot, Also, the Comparison of NO2 concentration in each sit shows that NO2 near busy road is higher than residential area and industrial area. It is considered that the measurement of air pollutant using passive sampler is suitable for the areas such as industrial complex widely.

This article describes two and three dimensional electromagnetic finite element models for an active heteropolar radial magnetic bearing, the procedure for obtaining the bearing stiffnesses by simulating the models and the reviews of the models by comparing an experimental test to the ideal closed loop analysis with the stiffnesses calculated. The three dimensional model for the magnetic bearing may be very effectively applied to several types of magnetic bearings.
