Oxygen deficiency has been frequent in a clouted space. Wood consumes oxygen and discharges carbon dioxide Instead of photosynthesis in closed space without light, so do some microorganisms on the surface. We experienced a case that a healthy Insect-proofer fell down and died of asphyxia on stair-board at 7 m below the hatch of the cargo-hold shipping wood Analysis of gases in cargo-hold revealed O2; 12.3%, CO; 105 ppm, CH4; 2.7%, and H2S; 1.9% at 1 m below the hatch, and then O2; 6.1%, CO; 220 ppm, CH4; 2.9%, and H2S, 2.3 ppm at 2.5 m below the hatch. Autopsy findings were unremarkable. We justiced the cause of death asphyxia due to oxygen deficiency. As seen in this case, the serious oxygen deficiency was accounted for oxygen consumption by wood and microorganisms.

목적: 중소규모 사업장 근로자들의 직무 스트레스로 인한 결근, 조퇴의 현황과 한국형 직무 스트레스 하부 요인과의 관련성을 알아보고자 하였다. 방법: 중소규모 사업장 83곳 근로자들에 대해 한국형 직무스트레스요인 평가도구-단축형(KOSS-SF)과 사회 일반적 특성, 직업적 특정 및 직무스트레스로 인한 결근이나 조퇴 경험여부 등을 묻는 구조화된 자가 기입식 설문을 실시하였고, 응답한 4,350명에 대해 최종 분석을 시행하였다. 직무스트레스로 인한 결근, 조퇴와 한국형 직무스트레스 하부 요인들과의 관련성을 확인하기 위하여 로지스틱 회귀분석을 시행 하였다. 결과: 직무 스트레스로 인한 결근, 조퇴를 한 근로자는 남자에서 7%(196명), 여자에서 8%(113명) 로 조사되었고 한국형 직무 스트레스 하부요인과의 관련성에서는 남, 여 모두 직무요구, 관계갈등, 조직체계, 보상부적절, 직장문화 영역의 스트레스가 높은 군에서 통계적으로 의미있게 직무스트레스로 인한 결근, 조퇴율이 증가하였다. 결론: 중소규모 사업장 근로자들의 직무 스트레스로 인한 결근, 조퇴와 한국형 직무 스트레스 하부요인과의 관련성은 남자에서는 조직체계 영역이 가장 높았고, 여자는 직장문화 영역에서 가장 높은 관련성을 보였다. Objective: The aim of this study was to examine the actual conditions of absence and early leave due to job stress of 4,350 workers in 83 small and medium scale industries, and its relationship to job stress factors using Korean Occupational Stress Scale-Short Form (KOSS-SF). Methods: A structured self-reported questionnaire was used to assess each respondent's Sociodemographics, job stress, experience of absence and early leave due to job stress. Seven KOSS-SF domains of job stress were used. We estimated the relation of absence and early leave due to job stress and job stress factors using logistic regression analyses. Results: Absence or early leave due to job stress occurred in 7% of male workers and 8% of female workers. Multiple regression analysis revealed a significantly positive association job stress-related absence/early leave and job demand, interpersonal conflict, organizational system, lack of rewards and occupational climate. Conclusions: Absence and early leave due to job stress is significantly attributed to organizational System and lack of reward for men, and occupational climate and organizational system for women.

Background: Micafungin, a potent inhibitor of 1,3-β-D-glucan synthase, is a novel antifungal agent of the echinocandin class. In vitro study showed that micafungin was effective against Aspergillus species as well as Candida species, but clinical data on the prophylactic efficacy against invasive fungal infections (IFIs) other than candidiasis are still lacking. Materials and Methods: We identified 60 consecutive adult hematopoietic stem cell transplantation (HSCT) recipients who received at least 3 doses of micafungin during neutropenic period. Micafungin was started as an alternative in patients who were intolerant or had adverse events (AEs) to primary prophylactic antifungal agents. We retrospectively reviewed the medical records and analyzed the efficacy and safety of micafungin for prophylaxis against IFIs. Results: The patients either had autologous (n=9) or allogeneic (n=51: 1 syngeneic, 24 sibling, 26 unrelated donor) HSCT. Itraconazole oral solution (n=58) was the most frequently used first line antifungal agent for prophylaxis and was administered for median 11 days. The most frequent cause of switch to micafungin was vomiting (n=42). The duration of neutropenia and micafungin administration was median 13 and 12 days, respectively. A successful outcome was achieved in 45 (75%) patients. Empirical antifungal therapy was initiated in 13 (22%) patients. There were 2 cases (3.3%) of breakthrough fungal infections which comprised a probable invasive pulmonary aspergillosis and a possible invasive fungal sinusitis. There was no case of invasive candidiasis. A total of 53 (88%) patients experienced at least one AE regardless of causality during micafungin administration. The most frequent AEs were hypokalemia, vomiting, diarrhea, and elevated serum aspartate aminotransferase or alanine aminotransferase. Among the aforementioned AEs, only 1 case of diarrhea could be classified as a probable relation with micafungin when causality was assessed. There was no AEs that caused discontinuation of micafungin. Conclusions: Micafungin seems to be a safe and effective agent for prophylaxis of IFIs including aspergillosis as well as candidiasis in HSCT recipients. However, further large, prospective, and randomized comparative studies are warranted for aspergillosis.

목적 : 제일제당에서는 녹농균의 세포외막 단밸질을 유효성분으로 하는 백신인 CFC-101을 개발하였으며, 동물시험에서 이 백신의 안전성과 유효성을 입증하였다. 본 연구에서는 이 녹농균 백신의 인체에 대한 안전성과 면역원성을 평가하는 동시에 인체 접종시의 최적 투여 용량을 결정하기 위하여 제 I/Ⅱa상 임상시험을 수행하였다. 방법 : 건강한 성인 남자를 피험자로 선별하여 각 용량군에 백신투여자 6명, 위약투여자 2명을 배정하였다. 백신 투여군은 0.25mg, 0.5mg 또는 1.0mg 용량의 녹농균 백신을 7일 간격으로 3회에 걸쳐 근육주사 하였으며, 위약 투여군에게는 세포외막 단백질을 제외한 동일한 성분을 투여하였다. 백신접종 후 국소적 또는 전신적인 반응의 발생여부를 관찰하고, 혈액시료를 체취하여 백신의 역가와 유효성을 검정하였다. 결과 : 녹농균 백신 CFC-101은 모든 접종자에서 양호한 내약성을 보였다. 또한 0.5mg 과 1.0mg 백신 투여군에서는 100%의 항체양전율을 나타내었다. 생성된 항체는 녹농균 세포외막단백질에 특이성을 보였고, 녹농균 감염에 대해 방어효능이 있었다. 결론 : 이와같은 결과로부터 이 녹농균 백신은 인체에 안전하게 투여할 수 있으며, 높은 항체 생성능으로 감염방어 효능을 보이고 0.5mg과 1.0mg이 최적용량인 것으로 판단되었다. Background : We developed a Pseudomonas aeruginosa outer membrane protein(OMP) vaccine CFC-101, and the prophylactic efficacy of which has been demonstrated in animal models. In order to evaluate the safety and immunogenicity of the P. aeruginosa vaccine, we carried out a phase I/Ⅱa clinical trial in healthy male volunteers. Methods : Groups of eight volunteers, including two placebo subjects, were vaccinated intramuscularly with three doses of 0.25, 0.5 or 1.0 mg of the vaccine at one week intervals. Sings of systemic and local reactions observed after vaccination were recorded for each vaccinee for 5 days. Physical examinations were performed on days 0, 1, 7, 8, 14, 15, 21, and 42, and clinical laboratory tests were done on days 0, 3, and 21. Blood samples for assay of serum antibody levels were obtained up to 42 days after the first vaccination. Results : The vaccine was generally well tolerated by all vaccinees, showing no significant side effects. In the three dosage groups, all vaccinees, except one receiving the 0.25 mg dose, showed significant elevation in serum IgG antibody titers against the vaccine proteins, indicating 100% seroconversion in 0.5 and 1.0 mg groups. The human antibodies induced by the vaccine were specific for P. aeruginosa OMPs, as confirmed by western blot analysis and immunoprecipitation assays. The capacity of the human antisera to enhance opsonophagocytic killing activity by polymorphonuclear leukocytes and to confer protection against P. aeruginosa infections indicates that the antibodies elicited by the vaccine have protective efficacy. Conclusion : We conclude that the P. aeruginosa OMP vaccine is safe and effective for human use and its optimal dose to be 0.5 or 1.0 mg.

김인태,이동욱,이인구,성낙진,박기흠 東國大學校醫學硏究所 2002 東國醫學 Vol.9 No.2

목적 : 우리나라의 고등학교 3학년 학생들은 대학입시를 앞두고 많은 스트레스 환경에 놓여있으나, 그에 대한 연구는 충분하지 않았다. 본 연구는 고등학교 3학년 남학생들을 대상으로 생활습관과 스트레스 정도, 스트레스 대처방법을 알아보고 생활습관과 스트레스, 성적과의 상호 관계를 살펴보고자 하였다. 대상 및 방법 : 수능시험을 치른 포항 모 남자 고등학교 3학년 454명을 대상으로 2000년 11월 29일 자기 기입식 설문지를 이용하여 성적, 스트레스량, 스트레스 해소방법을 조사하였다. 스트레스 측정은 외래용 스트레스량 측정도구인 BEPSI (The Brief Encounter Psychosocial Instrument) 번역판을 사용하였다. 결과 : 조사대상자의 성적과 생활습관과의 관계를 본 결과 생활습관 중에서 아침식사(p<0.05), 규칙적인 식사(p<0.01), 규칙적인 수면(P<0.01), 부모와의 대화(P<0.05), 흡연(P<0.05)이 성적과 통계적으로 유의하였다. BEPSI 점수는 성적 및 스트레스 해소방법과 유의한 관계가 없었다. 생활습관과 BEPSI 점수와의 관계는 규칙적인 식사(P<0.05), 부모와의 대화(P<0.05), 주 2회 이상의 음주(P<0.01), 흡연(P<0.01) 등에서 통계적으로 유의한 관계가 있었다. 건강 생활습관 갯수와 BEPSI 점수는 유의한 관계가 있었다(P<0.01). 결론 : 고3 남학생들은 건강한 생활습관과 학교성적이 비례하였고, 건강습관 갯수와 스트레스량은 역비례하였다. 그러므로 고등학교 3학년 시기에는 좋은 생활습관을 가지는 것이 중요하다. Background: There are many stressful environment in the twelfth grade students who will take an entrance examination. But the investigation about twelfth grade students were not studied enough. Therefore we investigated the relationship between life style, school record and stress in the twelfth grade students. Methods: In November 29,2000, we surveyed 454 twelfth grade male students who has taken entrance examination for a university in a high school located in Pohang. Self report questionnaire was administered to measure school record, coping method, life style and stress. Stress amount was measured by Korean-translated BEPSI score. Results: There was significant relationship between school record and life style such as breakfast. regular diet, regular sleep, enjoy conversation with their parents and smoking. School record and coping method were no significant relationship with BEPSI scores. There was significant relationship between BEPSI scores and life style such as regular diet, enjoy conversation with their parents, smoking, drinking more than two times a week. The number of healthy life styles number was significantly related to BEPSI scores. Conclusions: Healthy life style was proportional to good school record and inversely proportional to stress amount in twelfth grade male students. Therefore, we conclude that it is important to keep healthy life style in the twelfth grade.

敎育의 兩面性 : 行動主義敎育과 人本主義敎育의 統合을 中心으로

金東球 西原大學校 1978 西原大學 論文集 Vol.7 No.-

There are two giant forces in education today-the first driving towardaccountability, behaviorism and the second toward a humaness, humanism in education. Theaccountability people, mostlycomprised of what we call scientific behavioristic type, have large amounts of data accumulating that seems incontestable. On the otherhand, and just as incontestable are the number and popularty of books currently on the market that deplore the irrelevance of the scholatic achievement pressure and announce a crisis in the education because of the lack of hummaness therein. I am expressing my belief that both system of thought have muchto offer all of usin the proffession of education. Wether we think in terms of behaviorism and humanism; or in terms of an objective-based system vs. a subjective based system; or in terms of learning theories based on different premises-anyway we view it, the mariage of two system is the helpful, responsible, profitable way for us to go. The pursuits in both camps have clarified the basic tenets for us. Their fellowers, perhapsbeing less well informed, have offen overdrawn the conflict and ingaged in much finger pointing debate that has only served to create an either and or stance that must be recognized as patenly ridiculous. We are in the verge of a major break through in education based on taking the best from each of these twotheories and breaking free of past conflicts. The majority of humanists are not ignorant of the principle of behaviorism as an unacceptable goal. The behaviorists offer humanists many techniques and method being used today. The majority of behaviorist are not ignorant of the principle of humanism as an unacceptable goal. The behaviorists offer humanists are not ignorant of the principle of humanism as an uncceptable goal. The behaviorisms offer humanists many techniques and method being used. Combs postulates that we needboth system-both behaviorism andhumanism. Educators need touse them at appropriate times for appropriate goals. Criticism of either system comes from those among educators who try to use only one system for all instructional activities. Popham postulates both behaviorism and humanism are tools and educators all be skilled in using either as needed. We, educators wish to improve instruction, improve skills in the basics, improve human relationship, selfconceptand desire for learning. Educators can teach all these things if they accept behaviorism and humanism.

김동현,박신구,김환철,이의철,김정훈,임종한 大韓産業醫學會 2008 대한직업환경의학회지 Vol.20 No.2

목적: 국내외를 통해 직무스트레스와 감기 등과 같은 감염질환과의 관련성에 대한 연구는 많지 않으며, 특히 국내에서의 연구는 거의 전무한 실정이다. 이에 직무스트레스와 감기와의 관련성을 확인하고자 한다. 방법: 일개 대학병원의 산업의학과에서 보건관리대행을 이행하고 있는 83개의 사업장, 근로자 6,699명에 대해 한국형직무스트레스-단축형(KOSS-SF) 설문지를 배부하였고 회수된 4,637명의 설문지 중 부적절한 응답과 다른 호흡기와 관련한 폐질환을 앓고 있는 237명을 제외한 최종분석 근로자 4,400명(65.7%)의 설문자료를 근거로 연구를 시행하였다. 결과: 감기 경험과의 단변량분석에서 유의한 차이를 보인 요인들과 일상생활 스트레스를 보정한 후 시행한 직무스트레스와 감기 경험과의 로지스틱 희귀분석 결과 직무 자율성 결여를 제외한 직무스트레스 하부 영역 전반(직무요구, 관계갈등, 직무불안정, 조직체계, 보상부적절, 직장문화)에 걸쳐 통계적으로 유의한 차이를 보여주었다. 또한 직무스트레스와 감기 경협 첫수와의 관련성을 확인하기위한 다중회귀분석에서도 비슷한 양상을 보였다. 결론: 직무자율성 결여를 제의한 한국형 직무스트레스 요인 전체가 감기와 관련성을 나타내었다. Objectives: To investigate the relationship between job stress and the common cold which is one of the most common infectious disease. Methods: A KOSS (Korean Occupational Stress Scale)-based questionnaire survey was conducted targeting 6,699 workers, of which 4,637 questionnaires were returned and the data for 237 were excluded due to poor response and having pulmonary disease other than common cold. Consequently, 4,400 (65.7%) returned questionnaires were analyzed. Multiple logistic regression analysis and multiple linear regression, adjusted for daily life stress, confounding variables and both, were used to evaluate the relationship between job stress and the common cold. Results: After adjustment for confounding variables and daily life stress, most of the subscales of job stress contributed to an increased risk of common cold. Conclusions: These results indicated that job stress may play a significant role in increasing the risk of the common cold and that further preventive efforts and studies are needed to reduce job stress and address infectious disease caused by job stress among Korean employees.

소양호의 DOC와 POC의 분포

김범철,최광순,김철구,이유희,김동섭,박제철 江原大學校 附設 環境硏究所 1998 環境硏究 Vol.15 No.-

Seasonal and vertical distributions of dissolved and particulate organic carbon were investigated from May 1995 to March 1997 in n deep mesotrophic reservoir, Lake Soyang, POC contentrations at the dam site ranged from 0.1 to 1.8 mgC/L and DOC concentrations ranged from 1.4 to 4.9 mgC/L. POC concentrations in the surface layer were higher in the season of cyanobacterial bloom, July to September. High POC was observed at the depth of 30 to 60m after storm runoff in summer monsoon season. Turbid storm runoff formed intermediate current laden with much particulate materials from terrestrial sources. The vertical and seasonal variation of DOC was smaller than POC. Higher DOC was observed near the lake bottom which implies sedimentation and degradation of much organic detritus at the bottom. The ratio of DOC : POC varied from 2 to 60, and the ratio was lowest in September 1995 when algal density was highest. DOC : POC ratio of the main inflowing river, the Soyang River, varied from 1 to 10, and the ratio was low in storm runoff when the POC concentration was high.
