This study was formed the basis of propelling for being closely connecting between School PE(Physical Education) and Local Society Exercise for regarding the cooperation possibility depending on the actual situation. From this, it is helpful for evaluating the total understanding of the present condition form School PE and Local Society Exercise and grasping the realities concretely. To gain the above result, the subject of study is on 48 agencies among 50 agencies that include 30 elementary and middle schools, 15 government offices, 5 YMCA offices. After investigating the plan of providing physical activity program except result PE class and the connecting program with School PE and its activation, it comes to the conclusion below this. There is the period of possible time for propelling the cooperating model at School and Local Society PE which is special activity class after school, club activity class, discretional activity class and the vacation, weekends. And also there are many participating agencies that are school, local society, public sports center and community, the youth group, local autonomous entity PE post, prfessional physical association and community, city and countries Education Office and the sports-lover's group etc. So far, the connecting program is operated at 24 agencies which are 3 elementary school(30%), 5 middle school(50%), 4 high school(40%)m 7 government office(70%), 5 YMCA office(80%). As the reason of non-operating it, the first is the lack of the charger, spare time and considering teacher's advantage when time is arranged at the teacher and leader's part. The second is the falling behind facility and the lack of place and appliance for practicing. The third is the insufficient of connecting program at program part and increasingly number of students who are individual participating at the side of local society physical agency at school. The forth is the lack of finances for running at economy part and overpaying of using fee. The fifth is the lack of the activity time at the elementary school and putting first in importance the exam for university enterance at middle and high school. The sixth is the parents and principals and school committee have little understanding of the physical educating in common at recognition part. The seventh is the cooperating company's preparation is not enough and incomplete relation each other. Looking into the opinion for activating plan of connecting program which is classified into common contents, the result is presented the same reaction both of them that the professional leader arrangement is needed at teacher and leader's part. At the facility expansion and open program part is required for a various program. In the case of school at economy condition part, more cheaper than expenses for facilities is needed and also the renovation of the education system And at the recognition part, the positive attitude of school is needed. At the safety part, the solution of safety problem for responsibility is needed. At the administration part, the support for professional agency and the change of systemic role for connecting agency.

연 x-선 현미경은 ‘물의 창’ 영역(2.3~4.4 nm)의 파장을 이용하여, 수십 nm의 분해능으로 세포를 파괴하지 않고 살아있는 상태에서 세포의 내부구조를 관찰할 수 있어 가시광선현미경과 전자현미경을 단점을 보완하는 특징을 갖는 세포 생물학 연구에 적합한 현미경이다. 그러나 기존 연 x-선 현미경은 광원으로 방사선 가속기를 이용하기 때문에 사용이 제한적이었다. 이에, 본 연구에서는 2.88 nm의 연 x-선을 광원으로 사용하는 소형 연 x-선 현미경을 이용하여, 내포작용에 의해 금 나노입자를 포획한 HT1080과 MDA-MB 231 세포의 영상을 약 60 nm 분해능으로 획득하였다. 금 나노입자의 세포에 대한 독성을 제거하기 위하여 폴리에틸렌 글리콜을 캡핑하였고, 2.88 nm 파장의 연 x-선에 대하여 충분한 조영효과로 인하여 세포영상에서 뚜렷한 대조도를 나타내었다. 내포작용에 의해 액포에 포함되어 있는 다양한 크기의 금 나노입자 군집을 확인하였으며, 세포내부의 액포의 분포상태도 관찰할 수 있었다. 따라서 고분해능을 가진 소형 연 x-선 현미경을 이용하여 금 나노입자를 세포내의 미세기관이나 특정 단백질에 표지하면 연 x-선에 대한 조영효과의 증가에 의하여 더욱 유용한 정보를 획득할 수 있을 것으로 생각한다. A compact soft x-ray microscope operated in the ‘water window’ wavelength region (2.3~4.4 nm) was used for observing cells with nano-scale spatial resolution. To obtain cellular imaging captured with colloidal gold nanoparticles using a compact soft x-ray microscope. The colloidal gold nanoparticles showed higher contrast and lower transmission more than 7 times than that of cellular protein on the soft x-ray wavelength region. The structure and thickness of the cell membrane of the Coscinodiscus oculoides (diatome) and red blood cells were seen clearly. The gold nanoparticles within the HT1080 and MDA-MB 231 cells were seen clearly on the soft x-ray microscopy. The gold nanoparticles were aggregated within vesicles by endocytosis.

본 연구에서는 황정 속에 포함되어 있는 생리활성 물질을 hexane, CHCl₃과 n-butanol층에서 각각의 성분들을 추출하였고, hexane층에서 분리된 화합물 I과 Ⅱ 중에서, 화합물 I의 봐학구조를 ¹H-nmr, ??, DEPT135, COSY, HMQC, HMBC 스펙트럼 및 MS 스펙트럼 등의 분광학적인 방법에 의해 결정하였다. 화합물 I의 구조는 9,12-(9E,12E) -octadecadienoyloxy) propanoic acid 임을 확인하였다. In this Paper, biologically active compounds were extracted using organic solvents as hexane. CHC1₃, n-butanol to give each component. Chemical structure of compound I was characterized using ¹H-nmr, ??, DEPT135, COSY, HMQC, HMBC spectrum and MS-spectrum, in separated compound I and Ⅱ from hexane layer. Finally, chemical structure of compound I was determined as 9,12-(9E,12E)-octadecadienoyloxy)propanic acid.

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.
