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 adsorption of oxygen and methane on the bundles of open-ended single wall carbon nanotube(SWNT) was studied using the volumetric adsorption qst was obtained from the adsorption isotherm measurements performed at different temperatures. The trend in the values of the methane isosteric heat of adsorption showed three regions, representative of the adsorption on the different types of adsorption sites. In case of oxygen, on the other hand, such distinguishable regions were not appeared in the N-qst graph. From the results of qst the binding energies of oxygen and methane adsorbed on open-ended SWITs were estimated.

尹柱敬,崔福衍 全南大學校 農漁村開發硏究所 1977 農業科學技術硏究 Vol.12 No.-

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.

Purpose: This study was designed to investigate sample’s general characteristics and compare depression degree among sample’s general characteristics and students’ major(nursing vs. other major). Methods: The subjects consisted of 318 university students. Data was collected by self-reported questionnaires, which were constructed BDI score. Data was analyzed by the SPSS/PC WIN 19.0 program. Results: The depression of nursing students and other major students was not significantly different according to BDI score. Statistically significant difference was identified among sleeping. Conclusion: Specific study focused on the practice time should be done to confirm the depression of nursing major and other majors. Detailed support programs which specifically deal with sleeping should be developed to effectively reduce the harmful effects of individual vulnerability. Therefore, prevention and management system to reduce depression degree for university students is needed.

Objective : This study was performed to investigate the relationship between social support and quality of life among cancer patients receiving radiation therapy. Matehals and Methods : The data were collected from 98 patients, who were receiving radiation therapy at two university hospitals located in GwangUJu, used by structured questionnaire. For statistical analyses of the association between quality of life and various characteristics, data were analyzed using t-test, ANOVA, Pearson 's correlation, and multiple regression analysis. Results: 1. There were 56(57.1%) males and 42(42.9%) females. Age ranged from 21 to 82 years. The primary sites of cancer were gastrointestinal tract (24.5%), lung (23.5%), breast (21.4%), and head and neck (11.2%) in order. 2. The mean scores of social, family, and medical support were 4.30 0.58, 4.49 0.78, 4.11 0.65, respectively. The score of quality of life was 5.83 1.63 (range: 1.95 ~ 9.05). 3. An analysis of the association between several factors of patients and quality of life showed that the statistically significant factors were age, the presence of distant metastasis, family support, medical support and social support. 4. As a result of the multiple regression analysis, only social support was significant (β=0.932, P=0.02) with quality of life, but age and presence of distant metastasis were not significant. Conclusion : This suggests that quality of life in cancer patients could be improved by strengthening the social support which consists of family and medical support. Further study would be necessary to evaluate separately several aspects of quality of life among cancer patients.

Objectives : The purpose of this study was to investigate the stress coping strategies and psychological charactehstics, such as combined psychopathology and tendency of symptom interpretation, in patients with somatization disorder. Methods : Thirty patients meeting the criteria of DSM-IV somatization disorder were compared with thirty controls. We evaluated the subjects using Symptom Checklist-90-Revised (SCL-90-R), Somato-Sensory Amplification Scale (SSAS), Symptom Interpretation Questionnaire (SIQ), and The Ways of Stress Coping Questionnaire (SCQ). Independent t-test and Pearson correlation analysis were used. Results : From the results of SCL-90-R subscales, the scores of somatization, obsession-compulsion, depression, anxiety, and psychoticism were significantly higher in patients with somatization disorder than nonnal controls. Somatization disorder patients had greater amplification of physical sensation in SSAS and significantly higher score in physical interpretation of SIQ compared with psychological or environmental interpretation, In the SCQ of somatization disorder patients, we observed generallylower levels of total coping scores than the control group and significant positive correlation between passive coping style of SCQ and psychological interpretation of SIQ. Conclusion : These results show that patients with somatization disorder have various psychopathology, greater amplification of physical sensation, physical interpretation tendency of symptoms, and insufficient copying strategy.

본 연구는 입원 정신질환자들의 생활습관과 수면의 질과의 관련요인을 알아보고자 시도되었다. 전남 나주시 국립나주병원 개방병동에 입원한 정신질환자 154명을 대상으로 2008년 7월 17일부터 7월 25일까지 인구사회학적 특성, 임상적 특성, 입원 생활습관, 입원병력특성 등을 설문지 및 병록지로 조사하였으며, Leeds Sleep Evaluation Questionnaire(LSEQ) 변형도구를 이용하여 수면의 질을 측정하였다. 입원 정신질환자들의 수면의 질 점수는 17.53±5.03점이었으며, 단순분석상에서 수면의 질은 인구사회학적 특성 등과는 관련이 없었다. 그러나 다중회귀분석 결과 과체중군에서, 입원횟수가 많을수록, 통증 정도가 심할수록 수면의 질은 나빴다. 반면, 수면제를 복용한 사람이 복용하지 않은 사람에 비해 수면의 질이 좋았다. 생활습관과 수면의 질과 유의한 차이가 없었던 것은 입원이라는 동일 환경의 한계 때문이라고 생각된다. 이상의 결과로 볼 때 입원 정신질환자들의 수면의 질을 높이기 위해서는 수면제 복용의 약물치료와 함께 체중조절을 고려하고, 통증에 대한 적극적인 대처가 이루어져야 할 것으로 생각된다. Objectives : This study was performed to identify the relations between daily habits and quality of sleep of the psychiatric inpatients. Methods: We interviewed 154 the psychiatric inpatients of open ward in Naju national hospital, Chonnam Naju, from July 17, 2008 to July 25 of the same year. Data was collected using disease records and a questionnaire about socio- demographic characteristics, clinical characteristics, habits in hospital, and characteristics in history of hospitalization. And we measured the quality of sleep using the subjective sleep questionnaire modified from Leeds Sleep Evaluation Questionnaire (LSEQ). Results: The scores of quality of sleep of inpatients were 17.53±5.03. Quality of sleep had no statistically significant relationship with various characteristics in the simple analysis. However, as a result of the multiple regression analysis, the sleep quality of the overweight group was low, and the higher frequency of hospitalization and more pain they had, the worse sleep quality was. However, the sleep quality of those who took hypnotics was higher than that of those who did not. Conclusions: This study suggests that there was no significant difference between daily habits in the hospital and the sleep quality because of limits to the same environment of being in hospital. Based on the results above, in order to enhance the sleep quality of the psychiatric inpatients, we should consider both medication which takes hypnotics and weight control and actively deal with the pain.
