This study is for the purpose of examining effects related to duty stress & duty satisfaction due to Police of officers' Physical exercise participation, helping more efficient duty Performance, and positive self-formation. Furthermore, providing basic data that can be helpful to the improvement of police duty. The objects of the study were police officers who were taking part in education program in Police Comprehensive Academy, and the number of police officers who answered the questionnaire is 356 police officers, but data used for real analyzation consist of 300 police officers. The tools for the study were based on Ivancevich's duty stress model in order to measure stress. And also questionnaire used on Kim yoon hee, Kim mae ja, Jo kyung soon, Lee hart kyung's study was used as a complementary tool. The instrument for measuring duty satisfaction rate was developed by Paula. And I used the instrument based on questionnaire that was used by Ko hee soon, Park ki hyung, Kim bum sik, Lee jong kil, Lim bun jang, Jo young chang, Hackeman, Lawlar and Oldham's study. Data analysis is Processed statistically with SPSS/PC+, I Performed T-verification, ANOVA-verification in accordance with the purpose of study after getting the percentage and the real number in case of general characteristics of the objects, and examine an average and standard variation in case of duty satisfaction and duty stress rate. And I set an err rate to 0.5. I verificated co-relation between stress and duty satisfaction with Pearson Correlation Coefficient. The result of the study is as follows, The first, among sociological characteristic and external factor of duty satisfaction, The married is more significant statistically(p< .01, p<.05) compared to the unmarried in terms of compensation system and working condition , which are subfactor of duty satisfaction . In terms of the length of one's service, the longer service term one has the higher significance level one shows in compensation system, working condition, safety, and external factor which are sub-factors of duty satisfaction In terms of an academic background, one who graduated from a high school shows significance statistically only in working condition which is a subfactor of duty satisfaction compared to other people (p<0.5) The second, among sociological characteristic and internal factor of duty satisfaction, the married is more significant statistically(P<.05) compared to the unmarried in terms of achievement which is a subfactor of duty satisfaction. In terms of age the older one shows higher significance level in stability which is a subfactor of duty satisfaction compared to younker one(p<.05) In terms of the length of one's service the longer service term one has ,the higher significance level one shows(p<.01, p<.05). The third, in terms of duty stress due to sociological variable, the married is more significant statistically(p<.05) in case of stress stems from police duty than the unmarried Interms of age, welfare and duty stress are significant statistically(P<.05) Interms of the length of one's service, police's work is significant statistically(P<.05). One who graduated from junior college is significant statistically in police's work, welfare, stress and gets a lot of stress in personal relations(p<.05). The forth, groups participating in exercise are more significant statistically in stability(p<.001), feeling of stability(P<.001), achievement(p<.001), internal factor(p<.01), external factor(p<.05) than croups not Participating in exercise. The fifth, groups participating in exercise are more significant statistically only in personal management than groups not participating in. The sixth co-relation between duty satisfaction and duty stress is r=-0.3814, (P<.001) ,which shows opposite co-relation. so, a result the more stress one has, the lower duty satisfaction he gets.

콘크리트 구조물이 대형화됨에 따라 설계단면이 증대되어 상대적으로 많은 경제적 손실을 부담하게 된다. 따라서 단면을 감소시키면서도 소요의 하중에 안전한 구조물을 건설하기 위해서는 우선적으로 구조물 건설에 기초가 되는 고품질, 고내구성의 고강도 콘크리트 개발이 절실히 요구된다 본 연구에서는 일정 시멘트비 및 혼화재 비율하에서 소요의 워커빌리티가 확보되는 고강도 콘크리트를 시간과 온도의 변화에 따라 증기 양생하여, 압축, 인장, 휨강도 뿐만 아니라 파괴특성을 실험적으로 연구하였다. 시료 제작시 시멘트 입자 사이의 공극 및 불연속 영역을 충전하여 고밀도화하기 위한 콘크리트용 혼화재로 시멘트 비표면적이 상당히 작은 초미립 분말인 실리카흄을 이용하였다. 또한 AE감수제 및 고성능 유동화제를 사용하여 혼화재의 첨가에 의하여 발생될 수 있는 워커빌리티의 감소를 방지하였다. 실험결과에 의하면 일정 양생 지속 시간하에서 온도의 증가에 따라 콘크리트의 압축, 인장 및 휨강도가 전반적으로 증가하였다. 동일하게 일정 온도하에서 양생 지속시간이 커짐에 따라 강도들이 증가됨을 알 수 있었다. 따라서 상대적으로 높은 온도와 긴 지속 양생 조건하에서 파괴에 대한 저항력이 크게 나타났다. The compressible, tensible, and flexibleresistance of the high strength concrete is analyzed by the experimentation in the present study. For the test, we cure several samples with the silica fume as a mixture being become dense the spaces between the particle of cement under the variation of both the temperature and the curing-interval. Then, the superplasticizer and the ezcon are also used to satisfy the required workability for construction. The compressible, tensible, and flexible resistances to a stress are increased as increasing the temperature and the time interval for the curing. Therefore it is concluded that the overal fractural and mechanical properties is improved by mixing the silica fume into the cement.

The objective of this study was to investigate the managing realities of EVD and provide a descriptive survey with the attempt to obtain basic data needed for the standardization of EVD management. For that purpose, 220 questionnaire copies were distributed to those nurses who were working with intensive care units at university hospitals, general hospitals, semi-general hospitals in Seoul, Kyongki-de and local areas. Of 158 returned questionnaire copies, 139 were used for analysis. Data were collected during the term of academic seminars of Neurosurgery Nursing Committee and KICA (Korea Intensive Care Association), ranging from Oct. 26 through 27. 2000. The tools utilized a structured questionnaire form consisting of 21 questions on general characteristics, the level of understanding, the level of work performance, standard management guidelines, etc. The data collected were analysed with frequency, percentage, mean vague, chi -square test using the SPSS 10.0 program Findings were revealed, as follows: For managing the prevention of EVD infection, aseptic technique was found to be of the most importance (48.9%),'the technique should be carried out at an operation room'(92.8%), but it was actually performed at intensive care units (over 51.5%). 'The term of antibiotics use should be less than 7 days' (81.8%), while it was actually executed for less than 7 days (49.5%). 'The proper time of quittance from it should be within less than 7 days'(74.1%) but actual quittance was executed only by 51.1%. 'Set exchange is needed' by 54.0% but actual exchange was implemented merely by 28.1%. 'The subject of management should be nurses' was reflected by 40% but actually 52.0% were carried out. As a result of hating analysed the understanding of the management of EVD by general characteristics, a significant difference was found in the necessity for set exchange by hospitals, in the time of quittance of a catheter, and in ablution items by work experience. The result of hating analysed the work performance levels of EVD management by general characteristics revealed that a significant difference in administration facilities of medicine by the classification of hospitals, especially the use of antibiotics and the quitting time of a catheter by the classification of intensive care units, and in the use of antibiotics and ablution items by the standard management guidelines.

이동근,김남영,장민경,이옥희,이상현,Lee, Dong-Geun,Kim, Nam-Young,Jang, Min-Kyung,Lee, Ok-Hee,Lee, Sang-Hyeon 한국생명과학회 2007 생명과학회지 Vol.17 No.1

A novel agar-degrading bacterium SL-5 was isolated from seashore of Homigot at Kyung-Buk province, and cultured in marine broth 2216 media. The bacterium SL-5 was identified as Thalassomonas genus by 16S rDNA sequencing with 96% identity. Growth rate was faster at $27^{\circ}C$ than at $37^{\circ}C$ and agarase was produced as growth-related. The optimum pH of the enzyme activity was 7.0 and the optimum temperature for the reaction was $40^{\circ}C$. Although the enzyme had no thermostability, the enzyme activity was remained over 80% at $60^{\circ}C$. The enzyme hydrolyzed neoagarohexaose to yield neoagarobiose as the main product, indicating that the enzyme is $\beta-agarase$. Thus, the enzyme would be useful for the industrial production of neoagarobiose. 포항 호미곶 해수에서 한천분해활성을 보이는 해양성 세균 SL-5을 분리하였으며 16S rDNA 염기서열분석으로 해양기원의 Thalassomonas 속과 가장 유사한 균주임을 확인하였다. SL-5 균주가 생성하는 한천분해효소(agarase)는 성장의존성인 것으로 확인되었고 효소활성을 위한 최적 pH는 pH 7.0(20 mM sodium phosphate 완충용액)이고 최적 온도는 $40^{\circ}C$로 나타났다. 한천분해효소는 $80^{\circ}C$까지 65%의 효소활성을 보이는 호열성 효소이지만, 내열성은 그리 높지 않았다. 한천 분해효소의 분해산물에 대한 TLC 분석결과, 본 효소가 $\beta-agarase$라는 사실을 확인할 수 있었다. 분리한 Thalassomonas sp. SL-5 균주가 생산하는 한천분해효소를 이용하여 한천으로부터 다양한 기능성 한천올리고당을 생산하는데 있어 유용하게 사용될 것으로 기대된다.

Background : Various types of protective footwear have been used to minimize bacterial contamination in operating rooms. In recent years, debate has arisen concerning the need for use of such protective footwear. This study was designed to provide useful data about choosing shoes most suitable for the surgical environment. Methods : Between November, 1999 and January, 2000, we performed this experimental study by comparing effect of three types of shoes (i.e., disposable shoescover, operating room-restricted shoes, and ordinary shoes) on bacterial contamination of operating rooms equipped with two different ventilation systems (i.e., high air-change, low air-change) respectively. Data were collected during two-hour sham operations in which subjects and their activities were strictly standardized. Bacterial flora were sampled from the study area floor and air colony-counts were measured. Results : In experiments involving high air-change ventilation system, there was a significant difference of floor contamination between three types of shoes, but no difference of air contamination. Under low air-change system, there was a significant difference of both floor and air contamination between three types of shoes. Conclusion : The results show that protective footwear would be unnecessary in the operating room with high air-change ventilation system, but it is important to choose suitable shoes carefully under low air-change system. Therefore, the use of outdoor shoes can be considered under high air-change system, but it would seem sensible to apply their first use in less bloody operations at the day surgery center or out-patient department to prevent transfer of body fluid into the outside environment.

이남경,윤재영,이서래 이화여자대학교 생명과학연구소 1995 생명과학연구논문집 Vol.6 No.-

현재 국내에서 유통되고 있는 캔 및 병 오렌지쥬스를 20,30,40,50℃에서 24주 동안 저장하면서 4주 간격으로 개봉하여 중금속(Sn,Fe,Pb) 함량, 비타민 C 함량, 갈색도와 pH의 변화에 대한 측정치로부터 온도별 활성화 에너지와 Q_10값을 계산한 다음 shel-life를 예측하였다. 캔쥬스의 품질지표로 삼을 수 잇는 것은 Sn,Fe,Pb함량, 비타민 C 함량이었고, 병쥬스에서는 비타민 C 함량, 갈색도이었으며 이들 품질지표에 대한 Q_10값은 1.3~2.0이었다. 쥬스를 50℃에 저장시 품질 허용한계에 도달하는데 요하는 기간과 Q_10 대표값으로 부터 shel-life를 계산하면 캔쥬스의 경우 10,20,30℃에서 각각 10,6,3개월 이었고, 병쥬스의 경우 각각 24,12,6개월이었다. 국내에서의 쥬스 유통온도를 평균 15℃로 가정할 때 적정 품질수명은 캔쥬스 8개월, 병쥬스 18개월로 평가되엇다. 캔 오렌지쥬스의 안전성을 확보하기 위해서는 식품공전Pb 허용기준(0.3㎎/㎏)의 재검토와 아울러 캔 재질의 개선을 위한 연구노력이 요구된다. Canned and bottled orange juices currently sold in Korean market were stored for 24 wweeks at 20, 30, 50 and 50℃ and analyzed after opening at 4 week intervals. Activation energy, Q_10 values and shelf-life at respective temperatures were calculated from the data on various quality indexes. Proposed indexes were lead, tin, iron and vitamin C contents in canned juices and vitamin C content and browning index in bottled juices and Q_10 values for these parameters were in the range of 1.3~2.0. Shelf-life calculated for canned juices at 10, 20 and 30℃ were 10, 6 and 3 months and that in bottled juices, 24, 12 and 6 months, respectively. When the distriburion temperature of juices in Korea is assumed to be 15℃ average, the optimum shelf-life was estimated to be 8 months in canned juices and 18 months in bottled juices. In order to ascertain the safety of canned orange juices, efforts are needed to re-examine the recommended distribution period, legal limit for lead and improvement of container materials.

心系領域疾患 火熱證에 사용된 附子의 活用에 대한 文獻的 硏究

이경애,권정남,이원철 동국대학교 한의학연구소 1998 東國韓醫學硏究所論文集 Vol.6 No.2

附子는 흔히 寒證이나 陰證을 치료하는 약물로서 火熱證을 치료하는 경우는 흔하지 않다. 景岳은 附子가 能引火歸源하여 制伏虛熱하는 효능이 있다고 하였다. 心系영역 질환의 치료에 있어서 附子가 寒證이나 陰證의 경우외에 附子가 火熱證을 치료하는데 이용된 例가 있는지 歷代의 문헌에서 찾아보고 그 處方에서 附子의 역할과 그에 따라 配合되는 약물 및 활용특징을 살펴보는 것은 附子를 이용한 心系영역 질환의 치료범위와 이해를 넓히는데 도움이 될 것이다. 心系영역질환 火熱證의 치료에 사용된 附子의 역할을 살펴보면 크게 네 부류로 나눌 수가 있으며 이들 유형에 따라 배합되는 약물의 종류도 다르다. 특히 많은 경우에서 滋陰藥과 배합되므로 賦滯하지 않도록 하는 藥物의 配合에 대하여 많은 임상적 연구가 있어야 할 것으로 사료된다. We inquired in the prescription including Radix Aconiti(附子) on the records of the past. According to the role of Radix Aconiti(附子), we can divide into four group. (1) In the case of excess in the upper and deficiency in the lower(上盛下虛), heat in the upper and cold in the lower(上熱下寒), Radix Aconiti(附子) supplies the fire from the gate of life(命門火) and the fire of deficiency type(虛火) is recurred into the origin(根源) by it. (2) In the case that Yang(陽) is kept externally by Yin(陰)-excess in the interior(陰盛格陽), and there is heat syndrome in the exterior with cold syndrome in the interior(裏寒外熱), Radix Aconiti(附子) can remove cold(祛寒) and revitalizes(回陽). (3) In the case of the heat of excess type syndrome(實熱證), Radix Aconiti(附子) treats heat-syndrome(熱證) with heat-clearing(淸熱) drug. (4) In the case of wind-syndrome(風證) and phlegm-syndrome(痰證), Radix Aconiti(附子) supplies the kidney-Yang(元陽) and promotes movement of the other drugs. According to frequency in use of drugs, we can divide into four group. (1) In the case of the fire of deficiency type(處火), Radix Aconiti(附子) is used with drugs of invigorating-Yin(補陰), invigorating-Yang(補陽) and diuresis(利水), such as Rhizoma rehmanniae(熱地黃), Cortex cinnamomi(肉桂), Fructus comi(山茱萸), Poria(白茯岺), etc. (2) In the case that Yang is kept externally by Yin(陰)-excess in the interior(陰盛格陽), Radix Aconiti(附子) is used with drugs of dispelling cold(祛寒) and revitalization(回陽), such as Rhizoma zingiberis siccatum(乾薑), Radix glycyrrhizae(甘草), Radix ginseng(人蔘), etc. (3) In the case of the heat of excess type syndrome(實熱證), Radix Aconiti(附子) is used with drugs of heat-clearing(淸熱), such as Rhizoma coptidis(黃蓮). (4) In the case of wind-syndrome(風證) and phlegm-syndrome(痰證), Radix Aconiti(附子) is used with drugs dispersing(發散), invigorating(補氣), enriching the blood(補血), removing the phlegm(去痰), heat-clearing(淸熱), such as Radix osterici koreani(??活), Radix ledebouriellae(防風), Radix ginseng(人蔘), Radix angelicae gigantis(當歸), etc. Especially in many of cases, Radix Aconiti(附子) is used with drugs of nourishing-Yin(滋陰), but it is hardly used with drugs of treating middle-jiao energy(中氣).
