最近 全南地方의 복숭아 果樹園에서 크게 問題視되고 있는 果樹園 雜草의 效率的인 藥劑防除를 爲하여 1976年부터 77年까지 2年에 걸쳐서 Paracol 40 E.C. Paraquat 24.5 E.C. Roundup 41 E.C.를 濃度, 回數, 時期를 달리해 一連의 防除實驗을 實施하였던 바 그 結果를 要約하면 다음과 같다. 1. 圃場實驗 1. 本實驗圃에 發生된 雜草의 種類는 9科 12種이었으며, 그 中 優点雜草는 쑥, 환삼덩굴, 망초, 여뀌, 소리쟁이, 둑새풀이었다. 2. Paracol과 Paraquat는 소리쟁이를 除外한 쑥, 환삼덩굴, 망초, 여뀌, 둑새풀에 對해 아주 優秀한 除草效果를 보여 주었으며, Paracol은 80g/10a, Paraquat는 100g/10a 濃度水準에서 95% 以上의 높은 殺草率을 나타냈다. 3. Roundup은 쑥, 환삼덩굴에 對해 200g/10a 濃度水準에서 95% 以上의 높은 殺草率을 보여 주었으나, 300g/10a 高濃度水準에서의 망초, 여뀌, 소리쟁이, 둑새풀에 對한 殺草率은 名名 73.1%, 81.9%, 70.4%, 58.8%로 Paracol이나 paraquat에 比하여 낮았다. 2. Pot 實驗 1. 藥劑의 撤布時期은 Paracol, Roundup이 다같이 開花期가 84.5%, 84.5%, 82,7%로 幼苗期의 72.1%, 74.3%, 71.5%나 生育盛期의 74.4%, 72.2%, 64.1%에 比해 높았다. 2. 藥劑의 撤布 回數에 따르는 殺草率은 Paracol, Paraquat, Roundup이 다같이 2回 撤布가 75%, 74.6%, 74.3%로 1回 撤布의 62.1%, 63.1%, 63.1%에 比하여 높았다. 3. 藥劑의 濃度, 時期, 回數에 따라 95% 以上의 殺草六을 보여 주었던 處理區 가운데 가장 效率的이라 생각된 區는 Paracol이 開花期에 80g/10a, 1回 撤布區와 幼苗期에 2回 撤布區와 幼苗期에 2回 撤布區였으며, Roundup은 開花期에 300g/10a 1回 撤布區와 幼苗期에 100g/10a 2回 撤布區였다. 끝으로 本 實驗을 遂行하는데 있어 積極的으로 協力해 주신 全北大學校 染 桓承 博士께 忠心으로 感謝를 드린다. Weeding in peach orchard, especially in spring and summer, is one of the most serious problems in Chonnam area. Control trials with several herbicides such as Paracol 40 E.C Paraquat 24.5 E.C and Roundup 41 E.C were carried out on the field as well as with the potted weeds for two years from 1976 to 1977. The results are summarized as follows: A. Field test 1. Weeds in peach orchard of the experimental farm, Chonnam National University were 12 species of 9 families, of which Artemisia oulgaris, Erigeron conadensis Humulus japonicus, Alopeculus aequalis, Rumex crispus and Polygonum hydropiper were the predominant ones. 2. All the weeds but Rumex crispus were effectively controlled by Paracol or Paraquat. Withering ratio of more than 95% was obtained by the application of 80g/10a of Paracol or by 100g/10a of Paraquat. 3. Roundup was proved to be less effective than the other two herbicides in controlling orchard weeds. Even though more than 95% of Artemisia vulgaris and Humulus japonicus could be controlled by 200g/10a, of Roundup only 73.1% of Erigeron eanadensis, 81.9% of Polygonum hydropiper, 70.4% of Rumex crispus, 58.8% of Alopeculus aequalis even by 300g/10a of Roundup. B. Pot test 1. Three kinds of herbicides, Paracol, Paraquat and Roundup were applied at different growing stages; seedling, vigorous vegetative growth, and flower bud formation. The difference in weeding effect among herbicides was not found. However, flower bud formation stage was proved to be the most appropriate time for herbicide application. The highest withering ratio of more than 81% was obtained from the application at flower bud formation stage compared to around 70% from those at other two stages. 2. Double applications of any herbicides resulted in about 75% withering ratios, which were higher than those (about 62%) form single application. 3. Among the treatments resulted in withering ratios of more than 95%, single application at flower bud formation stage or double applications at seeding stage with 80g/10a of Paracol, single application at flower bud formation stage or double applications at seedling stage with 100g/10a of Paraquat, and single application with 300g/10a at flower bud formation stage or double applications at seedling stage with 100g/10a of Roundup were considered as the effecient methods in controlling weeds in Peach orchard.

Background : Pneumocytitis cainii pneumonia (PCP) can occur in immunocompromised hosts especially such as AIDS or cancer patients. Although recent research had focused on PCP in AIDS patients, few studies have described the clinical presentations of PCP in recipients of stem cell transplantation (SCT). We evaluated the clinical manifestations of PCP in SCT patients admitted at St. Mary's hospital, Seoul, Korea. Methods : The medical records of 17 PCP patients undergoing SCT between Feb. 1998 and Feb. 2000 were reviewed. The diagnosis of PCP was confirmed through the demonstration of Pneumocytitis cainii via either cytology of brochoalveolar lavage (BAL) or histological technique of lung biopsy. CMV disease and CMV infection were confirmed by BAL culture and antigenemia respectively . Results : Seventeen patients were all recipients of allogeneic SCT and 7 of 17 patients were performed non-sibling SCT. Patients presented with symptoms including brief period (4 ∼23 days) of fever (76%), dyspnea (70%), cough (64%), and signs such as rare(58.8%), Sixteen patients (94%) had been receiving immunosuppressive agent such as cyclosporine A (64%) or Fk506 (35%) without PCP prophylaxis. Eleven patients (64%) were treated with corticosteroid with mean dose of 16 mg/day prednisolone and mean duration of 4.6 months after post-SCT period. Twelve patients were co-infected with CMV. Another co-infected miCroorganisms were Pseudomonas aeruginosa, Mycobacterium tuberculosis, herpes simplex virus, parainfluenza virus, Average duration of treatment with trimethoprim-sulfamethoxazole (TMP/SMX) was 21 ±9 days. Four patients died, and three of them were related with PCP. Conclusion : PCP developed frequently in patients who were taking immunosuppressive drug due to graft versus host disease or were not taking TMP/SMX prophylaxis. High risk patients showing fever, cough, or dyspnea should be considered to take early bronchoscopic intervention for detection of PCP. When treat for PCP, it also be considered to the possibility of coinfection such as CMV. (Korean J Infect Dis 33:273∼279, 2001)

The purposes of this study are to evaluate the lighting environment of a university assembly hall and to make clear the problems of conditions of lighting operation. The field measurement on the illumination level and the questionnaire survey on subject response of the lighting environment with students were carried out at an assembly hall in C university, Cheongju. These survey were taken on 4th and 9th of December, 2002. The illumination levels of the assembly hall in the condition A (157∼403 lux) were lower than standard (400lux). The illumination levels of the condition B (16∼372 lux) and condition C (0∼1 lux) were poor. The illumination levels of the condition D (231∼510 lux) were somewhat lower than standard. It was found that the present condition of the lighting environment of the university assembly hall is inappropriate illumination level and uniformity for lecture.

오늘날의 측량의 내용은 우주측지기술의 실용화, 컴퓨터를 이용한 수치지도제작 및 인공위성에 의한 영상의 획득이 가능해짐에 따라 종래의 지상측량 및 지도제작의 범위를 뛰어넘어 크게 확대, 발전되고 있다. 그러나 우리나라의 측량학계는 이러한 시대적 변화를 능동적으로 주도해 가지 못하고 있으며, 내부적으로는 제도적, 기술적인 여러 가지 문제점을 안고 있고, 또한 측량업과 측량기술자의 위상은 사회적 공헌도에 비해 열악한 상태에 처해 있는 것이 오늘의 현실이다 따라서 본 연구에서는 우리나라 측량의 현황과 문제점을 조사, 분석하고 측량기술의 발전과 측량업의 건전한 육성을 위한 여러 가지 방안을 연구, 검토하여 미래지향적인 발전지표를 제시하고자 하였다. Nowdays the scope and the contents of surveying are enlarged from a small area of the conventional surveying and mapping to a large area of the practical use of space geodesy technology, digital mapping using computers and the development of remote sensing. However, there are many structual, technological problems on the Korean surveying and mapping field, therefore they cannot actively lead the new tendency of current movement of surveying. The social status of survey engineers and the surveying and mapping industry is lower than it deserves for its social contribution. In this paper, the present status and problems of Korean surveying and mapping field are reviewed and analysed, and proper scheme for future development of the field with the prospect of surveying technology and the sound cultivation of surveying industry is proposed.

1975年 7月 4日~ 9月 25日에 和順과 光山의 水畓作地帶에서 發生되고 있는 昆蟲을 1週日 間隔으로 25回 往覆으로 採集하였던 바 다음과 같은 結果를 얻었다. 1) 採集된 害蟲은 4目 12科 13種이며 여기에 寄生하는 天敵으로는 3目 3科 4種과 거미류 및 청개구리로 나타났다. 2. 優占種으로는 光山에서는 벼멸구, 흑명나방, 끝동매미충이며, 和順에서는 끝동매미충애멸구, 흰등멸구, 벼잎벌레였다. 3. 綜合防除區는 一般農家防除區에 比하여 天敵 活動이 活發하였으며 그 結果도 뚜렷한 것으로 나타났다. 4. 光山과 和順에서의 收量調査를 하여 본 결과 二個地域 모두다 無防除區에 比하여 防除區는 20%의 內外의 增收를 가져왔다. Injurious insects dwelling in paddy growing zones of Hwasoon and Kwangsan in Chonnam were collected over 25 times with a 7-day interval from July 4 to September 25, 1975. The results were as follows: 1. Collected insects were 13 species in 12 families of 4 orders. In addition to these insects, 4 species in 3 families of 3 orders and Anura and Araneae were as their natural enemies. 2. Dominant species found in Kwangsan area were Nilaparvata Iugens Stal, Cnaphalocrocis medinalis Guenee, Nophotettix bipunctatus cinctiops Uhler and in Hwasoon area were Nephotettix bipunctatus cinctiops Uhler, Delphacodes striatella Fallen, Sogota furcifera Horvath, and Lema oryzae Kuwayama. 3. Since the natural enemies were more active in the integrated control plots compared with the ordinary farmers control plots, It can be concluded that the integrated control was more effective. 4. Grain yield per hectare was increased by about 20% in the control plots compared with that of the decontrol plots in both of Kwangsan and Hwasoon.

Mon-0358 RAT 2kg 處理區는 除草效果나 收量에 있어서 慣行區 및 Machete 1DBT 3kg 處理區와 有意性이 없는 것으로 나타나 Machete와 더불어 本畓 除草劑로서 效果가 좋은 藥劑라고 본다. 2. Mon-0358 RAT 2kg 處理區와 8 DAT 4kg 處理區는 除草效果에 있어서 有意性이 없어 使用藥量은 RAT일 경우 2kg, 8 DAT일 경우 4 kg이 適當하다고 思料된다. 3. 이 地方 優生雜草인 알방동신이의 防除效果는 Mon-0358 RAT 2kg 處理區가 慣行區 및 其他 處理區에 比하여 가장 높았고, 물달개에 對해서는 Machete 1DBT 3kg 處理區와 7DAT 3kg 處理區가 慣行區 및 Mon-0358 處理區에 비하여 높았으며, 여귀버들에 對해서는 Mon-0358 RAT 2kg, 8DAT 4kg 處理區가 다른 處理區에 比하여 높았다.水循 本畓用 新除草劑 Mon-0358의 除草效果를 알기 爲하여 1975年에 本 大學校 畓作圃場에서 藥量과 時期別로 Machete와 比較하여 몇가지 實驗을 하였던 바 그 結果를 要約하면 다음과 같다. To find out the effect of weed control of Mon-0358 , new herbicide, in transplanted rice paddy, this field experiment was carried out by the ratio and time of application in compared with Machete on the test field of Agricultural College, Chonnam National University in 1975. The results are summerized as follows; 1. There was no difference in effect of weed control and grain yield among the application of 2kg Mon-0358 RAT(Right After Transplanting) and hand weeding, application of 3kg Machete 1DBT(Day Before Transplanting). Mon-0358 is considered as a excellent new herbicide with Machete in transplanted rice paddy. 2. There was no difference in effect of weed control between the application of 2kg Mon-0358 RAT and 4kg Mon-0358 8DAT(Day After Transplanting). The desirable ratio of application is considered 2kg in case of RAT and 4kg in case of 8DAT. 3. The application of 2kg Mon-0358 RAT was more effective to increase the percentage of weed control to Cyperus difformis which is a predominant weed in Chonnam area compared with hand weeding and other treatments. The effect of 3kg Machete 1DBT and 7DBT to Monochoria vaginalis was higher than that of hand weeding and Mon-0358. The effect of 2kg Mon-0358 RAT and 4kg 8DAT to Ludwigia prostrata was higher than that of other treatments.

The Balanced anesthesia has many benefits such as no air pollution, no hepatic or renal toxicity and postoperative pain relief compaired with inhalation anesthesia. The Study pointed out differences of cardiovasular change, serum glucose and cost among Inhalation (Enflurane), Propofol and Midazolam-Fentanyl. Thirty-three patients of ASA class I or II scheduled to undergo elective operations were classified randomly into 3 groups. Enflurane group(E) was induced with thiopental sodium 5.0mg/kg and maintained with 1.5-2.0 vol% Enflurane and 50% nitrous oxide. Propofol group(P) was induced with propofol 2mg/kg and maintained by the continuance of a intravenous infusion of propofol 6mg/kg/hr with which is supplied 50% nitrous oxide. Fentanyl group (F) was induced with midazolam 0.1mg/kg and fentanyl 4g/kg and maintained by the continuance of a intravenous infusion of fentanyl 4-6 g/kg/hr and midazolam 0.2mg/kg/hr with which is supplied 50% nitrous oxide. The results were as follows : 1. Systolic arterial pressure was increased significantly in two group (E & P group) at 1 min. after intubation (p<0.01) and decreased in three groups (E,P & F) at 10 min. after intubation (p<0.05). 2. Diastolic arterial pressure was increased in E group at 1 min. after intubation (P<0.01) and decreased in P group at 5 min., 10 min. after intubation (p<0.05). 3. Heart rate was significantly increased in E group at 1 min., 5 min. after intubation and P group at 1 min. after intubation (p<0.05). 4. Serum glucose was significantly increased in three groups at 60 min. after skin incision (p<0.01). 5. Cost was lower in P group than E and F groups.

The purpose of this study was to identify hindlimb muscle atrophy in stroke induced rat and determine the effect of endurance exercise on body weight, weight of hindlimb muscle during 7 days after stroke induction. Thirty four male Sprague-Dawley rats with 200-270g body weight were divided into four groups : control, control+exercise(Con+Ex), stroke, and exercise after stroke(St+Ex) group. The control group and Con+Ex group received sham operation and the stroke group and St+Ex group received right MCA occlusion operation by using silicon-coated probe. The Con+Ex and St+Ex groups ran on a treadmill for 20min/day at 10m/min and 10 "grade. Daily body weight and diet intake were measured every morning for 7 days. Cerebral infarction of stroke and St+Ex groups were identified by staining with TCC for 30minutes. The data were analyzed by Kruskd-Wallis test and Mann-Whitney U test using the SPSSWIN 9.0 program. Body weight of the control group at the 7th day increased by 18.3% significantly from the first day of experiment, that of the stroke group at the 7th day decreased by 6.7% significantly compared to the day of receiving right MCA occlusion operation. Body weight of the Con+Ex group at the 7th day increased by 10.3% significantly from the first day of experiment, that of St+Ex group at the 7th day also increased by 13.4% significantly compared to the day of receiving right MCA occlusion operarion. The total amount of diet in stroke group decreased significantly compared to that of St+Ex and that of control group. In stroke group the wet weight of both sides of soleus, plantaris, and gastrocnemius muscles decreased significantly compared to that of control group. The relative weight of affected(left) plantaris and gastrocnemius muscles decreased significantly compared to that of the control group. The difference between the weight of affected and unaffected soleus, plantaris, and gastrocnemius muscles were not significant in stroke group. The wet weight of right gastrocnemius muscles in Con+Ex group increased compared to that of control group. The relative weight of right gastrocnemius muscle increased significantly compared to that of the control group. The wet weight of St+Ex group increased significantly compared to that of the stroke group in both sides of soleus, plantaris, and gastrocnemius muscles. The relative weight of affected plantaris muscle increased significantly compared to that of the stroke group. The difference between the weight of affected and unaffected soleus, plantaris, and gastrocnemius muscles were not significant in St+Ex group. Body weight and wet weight of soleus, plantaris, and gastrocnemius muscles in the St+Ex group did not recover to the values of control group. Based on these results, it can be suggested that endurance exercise during acute stage of stroke can reduce muscle atrophv related to denervation. inactivity and undernutrition.
