Background : In recent years, gonorrhea has been panedemic and remains one of the most commom STDs in the world, especially in developing countries. Objective & Methods: For the detection of a more effective therapeutic regimen and assessing the prevalence of PPNG, we have been trying to study the patients who have visited the VD Clinic of Choong-Ku Public Health Center in Seoul since 1980 by means of the chromogenic cephalosporin method. Results: In 1996, 139 strains of N. gonorrhoeae were isolated, among which 53(39.0%) were PPNG. Conclusion: Our results suggests that after a peak of 74.3% in 1993, the prevalence of PPNG in Seoul is gradually declining.

분사식 주사기를 이용한 소아환자의 국소마취

이재춘,김대업,이광희,김성형,양계식 大韓小兒齒科學會 2001 大韓小兒齒科學會誌 Vol.28 No.4

소아치과에서 국소마취는 공포의 대상이며, 특히 행동조절이 힘든 소아의 경우 더욱 그러하다. 국소마취에 대한 공포는 주사침의 자입시나 주사액의 주입시 느끼는 동통 만큼이나 주사침 자체의 공포도 크게 차지한다. 주사침 자입시의 동통을 완화하기 위하여, 도포마취제 등이 개발되었으나 이들은 국소마취의 동통을 완화시키는 면은 있으나 주사침 자체에 대한 공포를 없애지는 못하였다. Syrijet Mark Ⅱ??(Mizzy Inc, USA)는 주사침이 없는 치과용 분사식 주사기(jet injection device)로서 소아에서 주사침에 대한 공포를 성공적으로 감소시킬 수 있다고 알려져 있다. 저자들은 여러 행동등급의 소아를 대상으로 Syrijet을 사용하여 국소마취를 시행한 후 동통평가의 척도로서 VAS(visual analogue scale)를 소아에게 적합하게 색생화한 CAS(color analogue scale)을 이용하여 국소마취시의 동통수준을 측정한 결과, 기존 주사침에 의한 국소마취시 보다 국소마취의 동통이 감소된 것을 알 수 있었다. Syrijet의 장점으로는 주사침이 없다는 점, 기존의 술식에서 일회용이었던 미취용 카트리지를 재사용할 수 있다는 점, 신경 및 혈관에 안전하다는 점 등이 있었으며, 단점으로 부피가 크며, 가격이 비싸며, 사용시 숙련성을 요구한다는 점 등이 있었다. Local anesthesia procedure in pediatric dentisty using needle-tipped syringes is stressful and painful for the child patients. The Syrijet Mark Ⅱ (Mizzy Inc. USA) is a jet injection instrument, which uses high pressure to propel fluids into soft tissue without the use of a hollow neeldle, so it seems to be able to reduce the injection phobia of the child patients. The authors compared the Syrijet with the conventional syringe by assessing the pain level after local anesthetic procedures using CAS(color analogue scale) which was developed from VAS(visual analogue scale). The result showed that the pain was reduced by the use of syrijet. The advantages of syrijet were no use of neeldes, the reuse of the anesthetic cartridge, and the safety to nerves and vessels. The disadvantages were the large size, the high price, and the need of skill to use.

이재형 국립7개대학공동논문집간행위원회 2005 공업기술연구 Vol.5 No.-

In this paper, CdS thin films, which were widely used window layer of the CdS/CdTe and the CdS/CuInSe2 heterojunction solar cell, were grown by chemical bath deposition, and the structural, optical and electrical properties of the films on reaction temperatures were investigated. Cadmium acetate and thiourea were used as cadmium and sulfur source, respectively, And ammonium acetate was used as the buffer solution. As the reaction temperatures were increased, the deposition rate of CdS films prepared by CBD was increased and the grain size was large due to increasing reaction velocity in solution, also optical transmittance of the films in visible lights was increased on rising reaction temperatures.

The present study deals with student circle activities at Pusan National University in an effort to improve student circle guidance. University circles are regarded as influencing an individual's self-growth. Two sources of data were used for this research. A total of 764 students at Pusan National University who were randomly sampled out of the registered students in 1982 Spring semester were the main subjects. Another source for the study were from 70 student circle leaders whose responses to another questionaire in a special leader training session held on October of 1982. Student respondents for this study were analyzed in three groups;(1) students who participate in circle activities at the time of the research, (2) students who participated in a circle in the past but not active at the time of the questionaire interview, (2) students who have never been members of a circle. The student respondents who were or have been members of the circles in which they participate:social service circles;academic circles; circles for special hobbies; religious circles; athletic circles for special hobbies; anti-communism circles. Some of the important findings from this research are summarized in the following. (1) Pusan National University students enjoy more student circle activities as demonstrated in the sheer number of student circle activities registered in the Student Affairs Section of the University. Circles with friendship purpose seem to decline, while circles for special hobbies and academic purposes tend to increase. (2) Many students were found to drop out of the circle activity mainly due to the lack of the circle activity information before their participation in those circle. More coeds than male students show this tendency. (3) Student circle members with specific purpose and goal in mind before participating in those circle regard aircle activity as contributing to the self-growth. (4) Many respondents think that circle activities are vital and necessary in the campus life. However, they do not find proper circle to paticipate. (5) The role of the student circle guidance professors was found to be important. (6) Problems for funding the student circles and finding meeting places for the circle activity remain to be solved. In short, the present study underlines the importance of the activization student activities which can be achieved through intensive circle guidance by circle advice professor and proper funding.

이준규,안재성,김형성 충남대학교 의과대학 지역사회의학연구소 1996 충남의대잡지 Vol.23 No.2

In ankylosing Spondylitis, ankylosis of some or all segments of the spine, segmentally or diffusely can be affected. Because all the ligaments become ossified in the involved area, a fracture that occur through this involved segment traverses both bone and ligaments, producing an extremely unstable situation similar to a shearing type of fracture. As the disease enters a chronic phase, the pathologic changes lead to a rigid, brittle, and osteoporotic spine. Mild trauma can lead to fractures that are difficult to diagnose, cause a high incidence of neurologic deficits, and present treatment problems. Patients known to have ankylosing spondylitis should be counseled regarding the possibility of a fracture, and if pain persists after an injury, they should be thoroughly investigated radiologically to rule out a potentially serious problem. Reduction of the displacement and stabilization is best achieved with posterior instrumentation, and laminectomy is not indicated. From March, 1990 to October, 1996, 11 cases of the ankylosing spondylitis in the department of orthopaedic surgery at Chungnam National University Hospital were managed nonoperatively with good healing and one case is operatively treated by anterior interbody fusion for cervical lesion, posterior instrumentation for thoracolumbar lesion.

李錫江,朴載植,金亨鎭 慶北大學校 醫科大學 1980 慶北醫大誌 Vol.21 No.2

一側 肺切除時 反對側 肺臟이 代償性 增殖을 한다는 것은 周知의 事實이다. 特히 代償性 增殖時 肺胞表面活性物質을 分泌하는 것으로 알려진 第Ⅱ型 肺胞細胞의 機能은 어떤 樣相을 나타내는지 究明하기 위하여 試圍한 本 硏究 結果는 다음과 같다. 肺洗滌液의 燐脂質 燐量은 對照群에서 8.04±0.74μMol/gm wet lung wt.인데 比해 肺切除後 第 1,2 및 3일에는 有意하게 減少하였으나 第 7일에는 6.91±0.57μMo1/gm wet lung wt.로서 第3일에 比해서 增加하는 傾向을 보였다. 肺洗滌液의 蛋白量은 對照群이 5.18±0.15㎎/gm wt lung wt.인데 比해 肝切除後 第 1 및 2일에는 各各 7.90±0.68 및 7.07±0.75㎎/gm wet lung wt.로 有意하게 增加를 보였으며 第 3 및 7일에는 對照群과 비슷하였다. 對照群의 右側肺臟 무게는 3.26±0.12gm인데 比해 肺切除後 第 1,2 및 3일에는 別 變化가 없었으나 第 7일에는 3.86±0.2gm으로 對照群에 比해 有意하게 增加하였다. 15㎖ 및 30㎖의 肺容積에 대한 肺內壓 測定은 動的 및 靜的肺內壓이 모두 肺切除後 第 1 및 2일에 上昇하는 傾向을 보였고 第 3및 7일에는 減少하여 對照群과 비슷하거나 낮았다. 兩側 副腎무게는 對照群이 230.2±19.5㎎인데 比해 肺切除後 第 1,2 및 3일에는 別 變化가 없었으나 第 7일에는 336.7±39.2㎎으로 對照群에 比해 有意한 增加를 하였다. 體重은 對照群에서 1.70㎏인데 比해 肺切除後 第 1,2 및 3일에 다같이 減少하였으며 第 7일에는 對照群의 그것과 비슷하였다. It is generally accepted that conpensatory lung growth occurs in the remaining tissue after pneumonectomy; the unilateral pneumonectomy causes the weights, number of alveoli, and alveolar cells to increase to the level of total paired lung, including alveolar type Ⅱ cell which secretes a lipoprotein mixture called surfactant. In order to study the effects of unilateral pneumonectomy on the function of type Ⅱ cell in the contralateral lung during compensatory period, left pneumonectomy was performed on rabbits (1.5-1.8kg body weight), and phospholipid phosphorus and protein contents in the right lung lavages, the weight of the right lung, intrapulmonic pressures at 15 and 30㎖ lung volumes, and bilateral adrenal weights were studied on the 1st, 2nd, 3rd and 7th postpneumonectomy day. The right lung was lavaged with isotonic saline and phospholipid phosphorus in the lung lavage was determined by the modified method of Beveridge and Johnson, and protein was determined by the method of Lowry et al. The results obtained are summarized as follows. Phospholipid phosphorus contents in the control was 8.04±0.74μMol/gm wet lung wt, but a significant decrease on the 1st, 2nd and 3rd postpneumonectomy day was observed compared with the control. However, phospholipid phosphorus on the 7th postpneumonectomy day was increased to 6.91±0.57μMol/gm wet lung wt comparing with the 1st, 2nd and 3rd postpneumonectomy day. The protein contents of the lung lavage was increased on the 1st and 2nd postpneumonectomy day but decreased to the control level on the 7th postpneumonectomy day. The lung weight on the 1st, 2nd and 3rd postpneumonectomy day was not different from the control but increased significantly to 3.86±0.25gm on the 7th postpneumonectomy day compared with the control value of 3.26±0.12gm. The static and dynamic intrapulmonic pressures were increased on the 1st and 2nd postpneumonectomy day but decreased to the control value on the 3rd and 7th postpneumonectomy day. The bilateral adrenal weight on the 1st, 2nd and 3rd postpneumonectomy day was not different from the control but increased significantly to 336.7±39.2mg on the 7th postpneumonectomy day compared with the control value of 230.2±19.5mg. The body weight in the control was 1.70±0.05kg but a decreased value was observed on the 1st, 2nd and 3rd postpneumonectomy day followed by a return to the control on the 7th postpneumonectomy day.
