The selective absorption ability of low density heavy metal(Pb(Ⅱ) ion or Cu(Ⅱ) ion) of eggshell(raw or boiled) is better than one of existing absorption materials in treatment ability and experimental condition. The elimination ability of chlorine of eggshell(raw or soiled) is worse than one of active carbon. In elimination of trihalomethane, the effect of treatment of eggshell is almost the same as one of pine cones. And surface of eggshell(raw or boiled) after absorption of heavy metal ion was observed by Scanning Electron Microscope(SEM). Application and availability of eggshell(raw or boiled) as absorption material need lots of experiments. The experiment on baked eggshell is proceeding.

This study was performed to identify risk factors for depression among the elderly in a rural area. A survey was done for the elderly living in Gosam-myenn, Ansung-kun during the period of July 28, 1997 and July 30, 1997. Demographic and sodoeconornic characteristics, and functional and health Status were assessed using a structured questionnaire, and the level of depression was measured by GDS score. The data obtained were analyzed by frequencies, percentage, t-test, ANOVA, and multiple regression, and the results were as follows: 1. The total sample consisted of 133 elderly. Of them, 47 elderly (35.4%) showed significant depressive Symptoms. 2. The GDS score was the highest for the group over 85 years of age (p < 0.05). Those living alone or widowed showed lower GDS score than those living with someone or married (p < 0.05). 3. The GDS score was the highest in the absolutely dependent group, followed by the partially dependent group, and the independent group (p < 0.01). The elderly who perceived their health Status as excellent showed the lowest GDS score. In contrast, those who had more than five chronic diseases showed the highest GDS score. 4. The elderly receiving financial and emotional support from their family or friends showed lower GDS score compared to those without any support. 5. The economically dependent group showed higher GDS score than that of independent group. 6. The elderly who involved in leisure activities showed lower GDS score than those without any involvement. 7. In terms of risk factors for depression, we found that perceived health Status, subjective economic Status, leisure activities, living arrangement and financial support were inversely associated with GDS score, whereas labor support was positively associated with GDS score. Based upon the above findings, this study suggests that these risk factors for depression in the elderly should be taken into consideration for a comprehensive mental health program for the elderly living in the rural area.

The purpose of this study was to develop a program for the enhancement of Korean married women's quality of life(LQ) based on the results of the first year study(1996) and the second year research(1998). In order to construct a program, a psycological type test was conducted to 505 women and four preliminary programs were carried out focusing on self-esteem, understanding of one's own personality dynamics, efficient communication, positive emotion, social belongingness and expressions of feelings of unfinished business. For the final program, Jung's theory of psychological type(MBTI), Satir's family therapy approach and psychodrama were applied. An experimental and a control group were designed consisting 16 women for each group. The program was carried out for 6 weeks for the experimental group. The result of treatment were as follows: l)There was a difference statistically in LQ related to family harmony, self-achievement and improvement of relationship with in-laws. 2)There was a statistical change in psychological factors of expression of feelings, self-esttem, communication, and positive emotions. 3) The program participants self reports indicate that the program was effective for the reconstruction of family relationship, self-understanding, group coherence, and instillation of hope. The reports also shows that the program was effective for the perceptual changes in parent-child, wife-husband and siblings' relationships. In conclusion, the program developed for the enhancement of Korean married women's life quality(LQ) based on the Jung's psychological type theory, Satir's family therapy approach and psychodrama was effective for the improvement of LQ.

The purpose of this study was to determine the changes in body composition, cardiopulmonary function, and flexibility following 8 weeks' bicycle ergometer exercise training. The subjects of this research consisted of healthy adult women between 30 and 40 years of age. Initial intensity of bicycle ergometer exercise was based on the target heart rate equivalent to 55% of maximal oxygen uptake, and intensity of the exercise increased by 5% every 2 weeks. Body composition, cardiopulmonary function at rest and during maximal exercise, as well as flexibility were determined before and after 8 weeks of bicycle ergometer exercise training. Masimal exercise was performed on the treadmill according to Bruce Protocol. The results obtained were as follows; 1. There were o changes in body weight, percent body fat, fat body weight, and lean body weight as well. The ventilation volume for 1 minute, respiratory quotient and expired CO₂ volume have not changed significantly after the training, either. 2. As a result of training, resting systolic and diastolic blood pressure decreased significantly(p<.05) 3. Maximal heart rate, maximal oxygen consumption and maximal running time increased significantly after the training(p<.05) 4. Pelvic flexibility increased slightly after the training, however, it did not reach the statistical significance. Trunk flexion forward increased significantly after the training(p<.05). From these results, it may be concluded that 8 weeks bicycle ergometr training improve the cardiopulmonary function and flexibility in healthy adult women between 30-40 years of age.

목적 : 2002년 말 중국에서 SARS가 발생한 이후 국내에서도 2003년 10월까지 총 3명의 추정환자, 17명의 의심환자가 보고되었다. 향후 추가적인 SARS의 유행이 우려되는 상황에서, 그간의 SARS 환자 진료에 있어서의 실질적인 준비사항, 진료 현황 등에 대한 조사를 통해 문제점을 파악하여, 향후 더 나은 대비가 될 수 있도록 개선점을 제시하고자 하였다. 재료 및 방법 : SARS로 의심되는 환자를 진료 경험이 있는 병원의료진을 대상으로 2003년 10월에 설문조사를 실시하였다. 설문에는 SARS 환자 진료 시의 실질적인 조치, 진료 현황, 병실, 응급실 및 외래에서의 격리 시설과 준비사항, 보건당국의 관리와 지원에 관한 사항을 포함하였다. 결과 : 대상이 되는 22개 병원 중 17개(17/22, 77.2%) 병원이 설문에 응하였다. SARS 환자를 위한 격리실은 응급실, 외래, 일반병실 및 중환자실에서 각각 9개(9/17, 52.9%), 5개(5/17, 29.4%), 15개(15/16, 93.7%), 4개(4/16, 25%) 병원에서 음압처리가 되어있지 않은 일인실 혹은 다인실이 사용되었고, 1개(1/16, 6.3%) 병원에서만 일반병실에서 음압격리실이 운영되었다. 입원환자의 진찰 시 개인보호구의 착용은 거의 모든 의료기관에서 이루어졌다. 보건당국에서 SARS지정병원의 시설 등을 사전에 확인한 곳은 1곳(1/12, 8.3%)이였고, 14개 병원(14/15, 93.3%)에서는 보건당국에 의뢰한 검사결과를 통하 받지 못하였다. 결론 : 의료기관에서 SARS 환자용 격리실뿐만 아니라 기존의 격리실 설비 등이 미흡하였으며, 특히 중환자실 및 외래의 준비가 더욱 부족하였다. 보건당국의 의료기관에 대한 종합적인 지원이 부족하였고, 병원과의 원활한 연계가 잘 이루어지지 않았다. SARS 만이 아닌 격리를 필요로 하는 질환의 적절한 진료를 위해 향후 병원 시설의 정비와 정부차원에서의 보다 구체적이고 실질적인 대책마련이 필요하다. Background : There was an worldwide outbreak of the Severe Acute Respiratory Syndrome (SARS) originated from China in late 2002. During that period three cases of suspected SARS and 17 cases of probable SARS were reported in Korea. With the concerns about the reemergence of SARS-coV transmission, it is important to be prepared for any possibility. So, this study is aimed to analysis the past measures in managing SARS and propose the amendatory plans to improve the preparedness. Materials & Methods : Questionnaires were collected among clinicians with any experience in managing the probable or suspected SARS cases in Oct. 2003. 17 out of 22 hospitals responded to the questionnaire. The contents in the questionnaire were practical activities, personal equipments, response plans, isolation facilities in emergency centers, outpatient clinics, general wards and intensive care units, and relationship with the public health department. Results : The dedicated isolation rooms in emergency centers, outpatient clinics, general wards, and intensive care units were prepared in 9 (9/17, 52.9%), 5 (5/17, 29.4%), 15 (15/16, 93.7%), and 4 (4/16, 25.0%) hospitals, respectively. Except for one hospital that newly made negative pressure room for SARS, single or multi-bed rooms without airborne infection control were used in all the other hospitals. The personal precaution principles were kept quite well in general wards. Before the designation of SARS hospital by the public health department prior evalution to see if the hospital was suitable for managing SARS was conducted in only 1 (1/12, 8.3%) hospital. The results of laboratory diagnosis were reported back in 1 (1/15, 6.6%) hospital. Conclusions : The isolation facilities which can control airborne infection were almost deficient not only for SARS but also for other respiratory transmissible diseases. For the infection control of transmissible diseases including SARS, more investment is needed on medical facilities and comprehensive support from the public health department required.

최병욱,송미숙,조정원 한국컴퓨터교육학회 2003 컴퓨터교육학회 논문지 Vol.6 No.1

차세대 인터넷 표준 언어인 XML(eXtensible Markup Language)은 데이터(data)와 표현(presentation) 그리고 구조(Structure)가 구분되기 때문에 어느 환경에서나 재사용성이나 재구성이 용이한 장점을 보이고 있다. 본 논문에서는 XML 문서를 가상교육 시스템(Virtual Education System)의 멀티미디어 컨텐츠로 범위를 제한하여 사용자 위주의 효율적인 검색 시스템을 구현한다. 본 시스템에서는 가상교육 표준안으로 제안되고 있는 SCORM(Sharable Content Object Reference Model)에서 정치한 SCO(Sharable Content Object)단위의 메타데이터를 기반으로 컨텐츠를 설계하고 각 문서를 키워드, 엘리먼트, 애트리뷰트 단위로 색인한다. 또한 사용자 인터페이스에서 앨리먼트 검색화면을 구조적으로 구성해줌으로써 사용자가 DTD(Document Type Definition)fl 대한 사전지식 없이도 검색이 가능하며, XML-QL로 재구성된 XML 문서의 형태와 XSL(extensible markup language Stylesneet Language)을 이용한 HTML 형태의 두 가지 결과화면을 제시함으로써 사용자 선택의 폭을 넓혀준다. XML(eXtensible Markup Language), next generation internet standard language has the advantage of easy re-use and re-structure in other computing environment because it has the separate data, presentation and structure. In this paper, we implement the efficient retrieval system for the general user by limiting the XML documents on the multimedia learning contents for the virtual education system. The system design is based on SCO Metadata unit defined in SCORM as the proposed virtual education standard. Each XML documents has three indexes keyword, element and attribute. Also, it makes Possible to retrieve data without previous knowledge of the 078 by making the element retrieval screen structure for the user interface. And it gives the user various result screen formats such as XML and HTML by restructuring the retrieval result through XML-QL and XSL, respectively.

흰쥐 적출 대동맥에서의 알파-1 아드레날린성 수용체 탈감작 현상

최도희,한형수,박정숙,김중영 慶北大學校 醫科大學 1994 慶北醫大誌 Vol.35 No.4

목적 : 흰쥐의 적출 대동맥 절편에서 알파-1 아드레날린성 수용체의 탈감작에 따른 수축력 변화를 확인하고 수축력 변화와 관련된 요인들과의 관계를 검정하기 위해 실시되었다. 대상 및 방법 : Sprague-Dawley rat의 대동맥을 적출하여 알파-1 아드레날린성 수용체 선택적 효현제인 phenylephrine으로 탈감작시킨 뒤 수축력과 이완력의 변화를 확인하였다. 결과 : Phenylephrine에 의한 수축력은 phenylephrine 탈감작에 의해 감소되었다. EDRF와 관련이 있는 이완제인 acetylcholine과 histamine에 의한 이완반응은 phenylephrine 처치로서 변화를 볼 수 없었으나 sodium nitroprusside에 의한 이완은 항진되었다. 탈감작현상은 LNMMA와 methylene blue처치로 인해 영향을 받지 아니하였다. KCl에 의한 수축은 phenylephrine 탈감작으로 억제되었으나 phorbol ester에 의한 수축은 phenylephrine 탈감작으로 인해 영향을 받지 아니하였다. 결론 : phenylephrine에 의해 나타나는 알파-1 수용체 탈감작에 따른 수축력 감소 현상은 이완 작용의 변화와는 관련이 없으며 수축기전의 변화, 특히 calcium에 대한 반응성의 변화에 기인함을 시사하였다. We evaluated alpha 1 adrenergic receptor desensitization and decreased contractility in isolated rat aorta. 4 hour exposure to 10^-5M of phenylephrine (phenylephrine exposure) decreased phenylephrine(10^-10 to 10^-5M)-induced contractility. Phenylephrine exposure had no effect on the relaxation by NO releasing agents, such as acetylcholine(10^-9 to 10^-5M) and histamine(10^-8 to 10^-4M), but enhanced nitroprusside(10^-10 to 10^-6M)-induced relaxation. Phenylephrine-induced desensitization was not altered by the presence of methylene blue and N-monomethyl-L-arginine. After phenylephrine exposure KCl-induced contractility was decreased but phorbol ester-induced contractility was not changed. From these results we can assume that prolonged phenylephrine exposure alter calcium-dependent contraction mechanism and involve in alpha 1 adrenergic receptor desensitization-mediated decrease in contractility.

수증기 개질반응용 니켈촉매에 첨가된 리튬의 효과

최재석,윤정숙,임태훈,홍성안,이호인 한국공업화학회 2005 응용화학 Vol.9 No.1

In the direct internal reforming type molten carbonate fuel cell, alkali carbonates used as electrolyte in the cell are transported to reforming catalyst of which activity drastically decreases. In our previous work, the deactivation of the nickel catalyst was studied with increasing the amount of added lithium. Unexpectedly, the increase of activity was observed with a small amount of lithium less than 1wt%. The results of TPR, XRD and chemisorption showed no significant difference between the fresh catalyst and the Li-added one, implying that lithium did not cause the change of morphological property of the supported nickel. To elucidate the effect of lithium the methanation of CO was applied to the catalysts, which was considered as the reverse reaction of the key elementary step of methane steam reforming. It can be seen by an online mass spectrometer that the small injection of CO/H₂ mixture into the Li-added catalyst reactor at 650 ℃ showed the longer tail of produced methane than into the fresh one. The delay should be originated from the effect of lithium, which determined the overall rate on the Li-added catalyst.

최형일,정경훈,정숙희 조선대학교 환경연구소 1998 環境硏究 Vol.14 No.1

Our has been advanced in the organization of society with rapid industralization for more over 30 years. Gravitation of the population and traffic increase made change in life style and brought about a lot of noise pollution which is not able to be confirmed in sight. The damage of traffic noise will be a serious problem, so the effective and economical countermeasuring of noise will be proceeded when we build up a large building or housing complex and it also needs enlightment activity in order to reduce sound by improvement of how drive. So, It is possible to be suggested as follows 1) Enforcing the every-ten-day limit on auto usage continuously. 2) Expended execution of noise restriction area. 3) Improvement of procedure in parceling-out. 4) Establishment of walfare facilities on the road side. 5) Application of matrial excluded the outside sounds in the construction on road side. If we consider environmental city condition at the construction and city planning, it is possible to minimize the noise pollution, to make a pleasant environment and to contribute the national health improvement.
