Background and Purposes: Over the past three decades, numerous studies performed in Korea have reported that job stress is a determinant risk factor for chronic diseases and work disability. Every society has its own culture and occupational climate particular to their organizations, and hence experiences different occupational stress. An occupational stress measurement tool therefore needs to be developed to estimate it objectively. The purpose of this study is to develop and standardize the Korean Occupational Stress Scale (KOSS) which is considered to be unique and specific occupational stressors in Korean employees. Subjects and Methods: Data were obtained from the National Study for Development and Standardization of Occupational Stress (NSDSOS Project: 2002-2004). A total of 12,631 employees from a nationwide sample proportional to the Korean Standard Industrial Classification and the Korean Standard Occupational Classification were administered. The KOSS was developed for 2 years (2002-2004). In the first year, we collected 255 items from the most popular job stress measurement tools such as JCQ, ERI, NIOSH and OSI, and 44 items derived from the a qualitative study (depth interview). Forty-three items of KOSS, in the second year, were retained for use in the final version of the KOSS by using Delphi and factor analysis. Items were scored using conventional 1-2-3-4 Likert scores for the response categories. Results: We developed eight subscales by using factor analysis and validation process: physical environment (3 items), job demand (8 items), insufficient job control (5 items), interpersonal conflict (4 items), job insecurity (6 items), organizational system (7 items), lack of reward (6 items), and occupational climate (4 items). Together they explained 50.0% of total variance. Internal consistency alpha scores were ranged from 0.51 to 0.82. Twenty-four items of the short form of the KOSS (KOSS-SF) were also developed to estimate job stress in the work setting. Because the levels of the subscales of occupational stress were gender dependent, gender-specific standard norms for both the 43-item full version and the 24-item short form using a quartile for the subscales of KOSS were presented. Conclusion: The results of this study suggest that KOSS might be an appropriate measurement scale to estimate occupational stress of Korean employees. Further and more detailed study needs to be conducted to improve the validity of this scale.

The incidence of hematologic disorders in patients with Down's syndrome is significantly increased, about 14∼30 - fold higher than in general population and includes neonatal transient abnormal myelopoieis and acute leukemias. The age of onset of leukemia in Down's syndrome is peaking first in the newborn period and then under 4 years of age. Down's syndrome with acute leukemia above the age of 20 is very rare and it's treatment oucome is unclear. The treatment of Down's syndrome with leukemia has been controversial because of toxicity and associated congenital cardiac and other abnormalities. But if treated adequately, children with Down's syndrome show a favorable response to anti-leukemia therapy. A 24-year-old man with Down's syndrome was first seen for the evaluation of anemia and thrombocytopenia. The peripheral blood morphology and bone marrow study revealed acute myelogenous leukemia, cytogenetic study of bone marrow showed trisomy 21. Beacuse of his sicioeconomic condition and medical abnormalities including deafness, visual loss, he was treated with low dose subcutaneous cytosine arabinoside(Ara-C) for 11 days. Complete remission was obtained after 37 days. The complete remission lasted for 5 months. He subsequently relapsed, and died 6 months later.

The project of desalinization in the new reclaimed land should be executed above all, because the damage of salinity in the paddy fields is due to the excess of salinity. Open ditch one of the most important methods of desalinization for expulsion of salinity by the irrigation water as well as decreasing the ground Water contained salinity. In this research, the effects of open ditch and of desalinization by irrigation water during the period of paddy plants growing, and changes of saline content in reclaimed land which is located in Kang-Hwa-Goon, Kyung-Ki-Do, were investigated. The results obtained in this research are summarized as follows: 1. The depth of saline expulsion by supplying of irrigation water was approximately 30cm to 50cm under the ground surface, but saline expulsion was hardly done in case of the depth which is deeper than the above mentioned, because the moisture and saline content hardly change in such a condition. 2. Infiltration speed of the Horizontal drainage was more rapid than that of vertical drainage in soil of Kang-Hwa reclaimed land. 3. In open ditch, we could make a good condition for the growth of rice plants, because the desalinization was not only rapid but also effective up to the subsoil layer. 4. The reasonable interval of open ditch was about 18m, and we could set limits approximately 30cm to 90cm in the depth of open ditch. 5. Saline changes of the soil in the reclaimed land was sensitive to weather condition and discharge of irrigation water, and changes of the monthly saline content was extreme in case of drying seasons and non-supplying of irrigation water, and saline content of surface layer seemed to be higher than that of subsoil. 6. The saline content of soil and the rate of disalinization showed a tendency to decrease according to cultivating years of rice plants. Rice plants was not nipped by salinity after 3 years cultivating in the conditin of open ditch by 18m iterval on the new reclaimed land.

Background : Gastric cancer is the most common malignant tumor in Korea. surgical operation is one of the major treatment modalities for gastric cancer patients. Therefore, gastrectomy is one of the most common procedures in General Surgery. There were variation in length of hospital stay and medical treatment for gastrectomy between three surgeons at Asan Medical Center. Clinical pathways have received considerable attention as a tool for recucing the medical practice variation, increasing the efficiency of care process, and improving the quality of care. The aim of this study was to evaluate the effect of a clinical pathway for gastrectomy in gastric cancer patients. Methods : The clinical pathway for gastrectomy was developed and implemented by a multidisciplinary group in Asan Medical Center. A computerized clinical pathway program was developed and revised after a pilot test. A total of 145 patients underwent gastrectomy by three surgeons at Asan Medical Center. We compared the length of hospital stay, patient satisfaction, and unplanned readmission rate between the pre-pathway group(n=67) and the post-pathway group(n=78). We also investigated the degree of satisfaction among the physicians and nurses who were main end-users of the clinical pathway. Results : The clinical pathway was applied to all target patients. The average length of hospital stay was shortened from 12.7days to 10.6days(p<0.01). The degree of patient satisfaction with the care process changed from 90.3% to 89.2% after the implementation of the clinical pathway, but the difference was of satistically significant(p=0.761). Unplanned readmission rate was 2.9% in the pre-pathway group. More than 90% of physicians and nurses answered that the clinical pathway had been a useful tool in their medical practice. Conclusions : The findings of the study demonstrated that implementation of the clinical pathway for gastrectomy produced substantial reduction in the length of hospital stay while improving the quality of patient outcomes. The computerized clinical pathway program can be used as one of the powerful patient management tools for reducing the practice variations and increasing the efficiency of care process in Korea hospital settings.

중증 재생불량성 빈혈 환자에서 신우신염에 대한 광범위항생제치료 중에 속발한 Saccharomyces cerevisiae 진균감염 1예

Most patients with aplastic anemia who do not respond to immunosuppressive treatment or are not candidates for bone marrow transplantation die of infection or bleeding. The neutropenia in acute leukemia, aplastic anemia, or occurring subsequently to chemotherapy and bone marrow transplantation increases susceptibility to infection. In general, the number of infectious episodes correlate with the degree and duration of neutropenia. Global immunosuppression produced by conditioning for bone marrow transplantation or graft-versus-host disease, is associated with unusual bacterial and fungal pathogens, or serious viral and protozoan infections. In addition, repeated treatment with broad-spectrum antibiotics is associated with the emergence of resistant organisms and fungal diseases because of the altered microbial microenvironment of the host. The incidence of invasive fungal infection caused by Saccharomycetes eerevisiae in immunosuppressed patients is very rare, compared with that of infection by candida or aspcrgillus species. Cases of Saccharomycetes cerevisiae fungemia occurring in the course of treatment with broad-spectrum antibiotics are reported in patients with extensive burn or with prosthetic valve endocarditis. We experienced a case of urinary tract infection by Saccharomycetes cerevisiae in a 27-year old female patient with severe aplastic anemia. We report the case with a review of relevant literatures.

연구목적 : 본 다기관 공동임상연구는 국내 환자를 대상으로 새로운 항정신병약물인 올라자핀의 치료 효과와 안전성을 확인하고자 시행되었다. 방 법 : 1999년 7월부터 2000년 3월까지 국내 10개 병원에 방문한 정신분열병 및 정신분열형 장애 105명을 대상으로 비대조 개방 임상연구를 시행하였다. 중등도 이상의 정신병 증상을 지니거나, 부작용으로 약물교체가 필요한 경우 또는 기분장애 증상의 치료가 필요한 환자를 대상으로 하였다. 2∼7일간의 약물 배설기간 후에 1일 10mg의 올란자핀을 투여하였고, 이후로 3∼7일 간격으로 용량을 조절하여 총 8주간 투여하였다. 치료 효과는 PANSS(Positive and Negative Syndrome Scale), BPRS(Brief Psychiatric Rating Scale), CGI(Clinical Global Impression-Severity), MADRS(Montgomery-Asberg Depression Rating Scale), HAM-A(Hamilton Rating Scale for Anxiety)로 판정하였다. 안전성 평가는 자발적인 이상반응 보고, 활력징후와 혈액 검사 및 SAS(Simpson-Angus Scale), BARS(Barnes Akathisia Rating Scale), AIMS(Abnormal Involuntary Movement Scale)척도를 이용하였다. 결 과 : 105명중에서 85.7%인 90명이 8주간의 치료를 완료하였다. 평균 최빈 용량은 일일 16.1(±4.7)mg이었고, 종료시점에서의 BPRS전체 점수가 기저 상태에 비해 40%이상 감소된 반응군은 69.5%이었다. PANSS의 양성 증후군과 일반정신병리 뿐만 아니라 음성 증후군 소척도에서도 유의한 감소를 보였으며, 이 감소들은 치료 초기부터 나타나서 8주간 지속되었다. 43.8%의 피험자가 중등도 이상의 우울증상을 같이 지니고 있었으며, 올란자핀에 의해 MADRS와 HAM-A가 유의하게 감소하였다. 치료 기간 동안에 활력징후에는 뚜렷한 변화가 없었으나 체중은 8주간 지속적으로 증가하였다. SAS와 AIMS는 감소하였으며, 정좌불능증을 제외한 나머지 추체외로 증상의 발생비율도 낮았다. 임상적인 증상이나 징후를 동반하지 않는 ALT/SGPT의 상승을 보였지만 프로락틴을 포함하는 대부분의 혈액 검사상 뚜렷한 이상 변화는 없었다. 결 론 ; 비록 본 임상연구가 비대조 개방 임상연구로서 많은 제한점을 가지고 있지만, 올란자핀이 기존 약물에 내약성을 보이거나 기분증상을 동반하는 정신병에 치료 효과가 있었다. 그리고 기존 항정신병약물 치료시에 문제가 되었던 추체외로 증상과 고프르로락틴 혈증을 포함하는 대부분의 부작용면에서 안전성을 보여 주었다. Objective : This multicenter clinical trial was carried out to investigate the efficacy and the safety of olanzpine for the treatment of Korean patients. Mothod : 105 patients with schizophrenia and schizophreniform disorder, visited at 10 mental or university hospitals, had received an open and non-comparative treatment with olanzapine for 8 weeks. Patients had psychotic or depressive symptoms with the severity above moderate degree or intolerable side effects to previous antipsychotics. After a wash-out period of 2-7 days, 10mg olanzapine was prescribed initially to all the patients, and then the dosage could be adjusted within the range of 5-20mg/day of olanzapine by 3-7 days. Results : 90(85.7%) of 105 patients completed the 8-weeks trial and the mean modal dose of olanzapine was 16.1(±4.7%)mg/day. At the end of the trial, 73 patients(69.5%) were classified as responder, which was defined as 40% or more improvement in BPRS(Brief Psychiatric Rating Scale) score comparing to baseline. There was a significant reduction in the scores of PANSS(Positive and Negative Syndrome Scale)and subscales including negative symptom scores and CGI. Also weekly analysis showed that the reductions in scores were kept on for the whole period of the trial. 43.8% of all the patients had depressive symptoms at the baseline and total scores of MADRS(Montgomery-Asberg Depression Rating Scale) and HAM-A(Hamilton Rating Scale for Anxiety) were also reduced after the trials. Vital signs revealed no clinically significant changes but continuous weight gain was observed during the treatment with olanzapine. The scores of SAS(Simpson-Angus Scale) and AIMS(Abnormal Involuntary Movement Scale) for assessing the EPS(extrapyramidal symptoms)and tardive dyskinesia respectively were significantly decreased and only a few patients reported EPS as adverse events. Although mild and clinically non-significant of ALT/SGPT was observed, most laboratory parameters including plasma prolactin level showed to significant changes during the trial. Conclusions : Although this trial had many limitations because it was a non-comparative and open study, olanzapine showed high efficacy on the positive, negative and depressive symptoms in schizophrenia and schizophreniform disorder.In addition to that, olanzapine showed a substantially favorable safety profile, such as low incidence of EPS and hyperprolactinemia.
