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.

Recently, land managers have come to realize that, outside Asia, camphor trees grow like street-tree or weeds, infesting forests and displacing native trees. This is because camphor trees are prolific seed producers that do not have serious predators or diseases outside their native range. The camphor tree (Cinnamomum camphora), belongs to lauraceae, is the aromatic evergreen tree from which camphor was derived. Headspace solid-phase microextraction (HS-SPME) and GC-MS were applied for the analysis of volatile fragrances emanated from camphor tree. Divinylbenzene / Carboxen / PDMS fiber was used for HS-SPME adsorption materials. (+)-Camphor (31.00%) and cineol (21.89%) were found as the major volatile aroma components from Chinese camphor tree, whereas (+)-camphor (62.06%) and β-caryophyllene (10.01%) from Japanese camphor tree. Camphor tree is a promising garden tree for well-being.

This study aims 1) to figure out the level of time conflict being experienced by employed wives. ;2) to find out factors influencing the time conflict.;3) to suggest the devices by which time conflict be solved. The results are as follows :1) the employed wives(75%) are mostly experienced time conflict. The wives' perceptions of time conflict are significantly different in the psychological involvement, flextime, and employed time. Their time conflict is increased in the case of unflexible work time, the employment by economic needs, wives attitudes involved in the family, and more time for employed work. Finally, Discussions were suggested to solve time conflict; 1) Lessen housework time and make various life content. 2) Divide housework and lower housework standard. 3) Put time management strategies to practical use.4) Apply flexible work time and expand a day nursery or public leisure facilities in the case of the children are infant and the inferior jobs.

This study suggested a business model for changing paradigm of retailing market. The study reviewed the changes of retailing service in different countries. Through the suggested business model, we analyzed the cost and benefit to the company. It has been increased to install the Off-site ATM and it showed that the retailing market tended to enlarge their service for customers. It may be extended other financial services such as loan payment. Retail market usually provide a place for installment of ATM but not managed direct service for customer's finance. However, it is a starting point that a few advanced retailing market introduced to direct management of ATM and offer a finanical service to their own customer. It needs to be better using cost-benefit analysis to enlarge those services before it has been applied for their marketing strategy.

피부단자검사, RAST 및 항원 기관지유발검사(allergen bronchial provocation test, ABPT)결과 쑥, 잔듸, 나무화분에 감작된 기관지 천식 환자 13명을 대상으로 이들 화분이 비특이적 기관지과민도(non-specific bronchial hyperresponsiveness, NSBR)에 미치는 영향을 알아보고, ABPT시의 조기 및 후기 천식반응(early, late asthmatic response, EAR, LAR)이 NSBR 생성에 관여하는지와 각각 화분의 항원성을 비교하고자, 감작된 화분으로 ABPT를 시행하고, 이를 전후하여 메타콜린 기관지유발검사(methacholine bronchial provocation test, MBPT)를 시행하여 아래와 같은 결과를 얻었다. 기저 폐기능상 기도 폐색을 보인 환자는 없었으며, 알레르기성 비염만을 호소하였던 환자 11명 중 4명(31%)은 MBPT에 양성반응을 나타내었으나, ABPT에는 11명 모두 양성반응을 보인 천식 환자였다. ABPT상 3명은 EAR, 2명은 ILAR, 8명은 LAR이였다. EAR만을 나타낸 경우는 ABPT 24시간 후 PC20이 감소하지 않고, 오히려 다소 증가하였으나, ILAR을 나타낸 환자들은 24시간 후 PC20가 감소하여 3일 후 기저치로 환원된 반면, LAR에서는 24시간 후 PC20가 현저히 감소하여, 2주 내지 6주 후에야 기저치로 환원되었다. LAR을 보인 환자들 중 쑥에 감작된 환자들이 목초 화분에 감작된 환자에 비해 Pc20의 감소기간이 유의하게 길었다. 이상의 결과를 종합해 보면 화분 흡입에 의한 LAR에 의해 NSBR이 악화되며 지속기간이 상당히 긴 것을 알 수 있다. 또한 화분 중 쑥의 항원성이 목초보다 상당히 강한 것도 알 수 있다. 더불어 화분에 감작된 알레르기성 비염 환자들의 대부분에서 천식이 잠재해 있음도 알 수 있다. 그러므로 향후 천식의 증상이 없는 화분에 감작된 비염환자라 할지라도 MBPT 및 ABPT를 시행하여 정확한 진단을 해야겠다. 본 연구에서 종래의 다른 연구 결과들과는 달리 쑥의 경우 ILAR의 경우도 NSBR을 악화시킴을 관찰하였는데, ILAR과 LAR의 차이가 단순한 기도폐색의 정도 차이인지, 기도 내에서 염증반응에 차이가 있는지는 향후 기관지 페포세척이나 조직 검사등을 통해 밝힘으로써, ABPT에 의한 NSBR의 발생 및 악화의 기전을 보다 확실히 규명할 수 있을 것으로 사료된다. Bronchial hyperresponsiveness is a fundamental characteristics in bronchial asthma. The pathogenesis of bronchial hyperreactivity has not been clearly understood, yet. We studied non-specific bronchial hyperresponsiveness with methacholine inhalation sequentially afterallergen provocation in pollen such as, alder, grass and mugwort-sensitzed allergic asthma and/or allergic rhinitis to investigate if there is any relation between allergen exposure and bronchial hyperreactivity, and compare the allergenicity of each pollen. 3 of 13 study subjects showed early asthmatic reaction, but 8 of them showed late(dual) asthmatic reaction, and the other 2 showed intermediate late asthmatic reaction. Non-specific bronchial hyperreactivity was not increased in early asthmatic responder, however, it was increased upto 45 days after allergen inhalation in all late asthmatic responder and in intermediate late reactor, upto 3 days. In mugwort-sensitized late asthmatic responder NSBR decreased much longer than any others. Taken together, pollen-induced late asthmatic reaction is one factor which contributes NSBR in pollinosis patients.

The purpose of this study was to evaluate the nutrient and food intake status in underweight female college students living in Seoul. 126 underweight(BMI <20) and 74 normal weight(20≤ BMI<25) students were asked for their daily food intake and eating habits by using 3-day food records and questionnaire. We analyzed the amounts of the nutrient intakes and food groups as the subjects. The mean of height and weight were 162.1㎝ and 49.0㎏ in underweight and 160.6㎝and 54.9㎏ in normal weight subjects. The mean energy, iron, and vitamin A intakes among the students were smaller than RDA for Koreans. The mean calcium(p<0.01), sodium(p<0.05), and vitamin B₂(p<0.05) intakes in underweight subjects were significantly higher than those in normal weight subjects. Total food intakes of underweight and normal weight students were 1235.8g and 1078.1g, respectively. The mean of the pulse group in the underweight was significantly higher than that in normal group(p<0.01). Frequently consumed food or dish items of the subjects were Kimchi, cooked rice, and milk. In the relation between BMI and dietary factors, the BMI was found to have a significant negative correlation with calcium intake(p<0.05), pulse intake(p<0.01) and eating habit score(p<0.01). Eating habit scores about quantity of food and lipid intake showed a significant difference between underweight and normal students.
