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.

Bioemulsifier를 생산하는 미생물을 토양으로부터 screening하였다. 그 중에서 유화활성과 유화안정성에서 가장 우수한 BE-254 균주를 순수분리하여 동정한 결과, Acinetobacter속으로 판명되었다. Bioemulsifier 생산을 위한 최적배지 조성은 n-hexadecane 4%, NaNO_3 0.2%, KH_2PO_4 0.05%, MgSO_4·7H_2O 0.05%, CaCl_2 0.01%, yeast extract 0.01%이였으며, 최적온도와 pH는 각각 30℃와 7.0이였다. 이러한 조건에서 500㎖용 shaking flask에 최적배지 50㎖를 넣어 배양했을 경우 대수증식기 말기인 5일째 균의 증식과 유화활성이 가장 높게 나타남에 따라 Acinetobacter sp. BE-254에 의한 bioemulsifier의 생산은 균의 생육과 밀접한 관련이 있는 것으로 판단되었다. 유화기질로서 hydrocarbon류, edible oil류, 그리고 petroleum fraction등에 작용시켰을 경우 이들 물질에 대해서 비교적 높은 활성을 나타내어 유화제 로서의 우수성을 시사 하였다. The strain producing bioemulsifier was isolated from soil samples. The isolated strain was identified as the genus Acinetobacter through its morphological, cultural and physiological characteristics. The highest emulsification activity and stability by Acinetobacter sp. BE-254 was observed after 5 days of cultivation in the culture medium containing n-hexadecane 4%, NaNO_3 0.2%, KH_2PO_4 0.01%, MgSO_4·7H_2O 0.01%, CaCl_2 0.01% and yeast extract 0.01%. The optimum pH and temperature for bioemulsifier production were pH 7.0 and 30℃, respectively. Furthermore the most of bioemulsifier was produced during the exponential growth phase, and this suggested that the bioemulsifier production was growth-associated. The bioemulsifier showed good emulsification activity on various emulsifying substrates such as hydrocarbons, edible oils, and petroeum fractions.

이 연구의 목적은 학생들의 생물학 가설검증방법의 유형을 분류 데 있다. 이를 위해 고등학생 35명과 대학생 40명을 표집 하여 수국, 제비 나비, 감자즙, 펭귄 등 4개의 가설검증 과제를 투입하였다. 각 과제에서 연구대상 학생들은 현상을 관찰하여 인과적 의문을 생성하고, 집단토의를 통해서 하나의 가설을 생성하였다. 그런 후 스스로 생성한 가설을 검증할 수 있는 방법을 고안하였다. 연구자들은 이렇게 고안된 학생들의 가설검증방법을 분석하여 몇 가지로 유형화하였다 그 결과에 의하면 먼저, 하나의 원인으로 된 가설의 검증유형은 직접 관찰법, 유사현상 비교법, 긍정 비교법, 긍정-부정 비교법, 비례 비교법 등으로 분류되었다 그리고 여러 개의 원인으로 된 가설은 크게 부분 검증법과 전체 검증법으로 구분되었고, 부분 검증법은 다시 단일 유형과 다수 유형의 하위 유형으로 구분되었으며, 전체 검증법은 유기적 유형, 기계적 유형, 혼합 유형 등의 하위 유형으로 구분되었다. The purpose of this study was to analyze the college students' and high school students' testing methods for biological hypotheses. Subjects were 35 11th grade students and 40 college students. Four hypothesis-testing tasks were developed and administered to the subjects: hydrangea, swallow butterfly, juiced potato, and penguin tasks. After being presented with the phenomena of the tasks, students were asked to generate questions and hypotheses and then to write a hypothesis-testing method on a questionnaire. Students' hypothesis-testing methods were classified into 5 types for mono-cause hypotheses; direct observation, similar phenomenon comparison, positive comparison, positive-negative comparison, and proportion comparison. In addition, students' hypothesis-testing methods were classified into 5 types for multi-cause hypotheses; mono type, poly type, organic type, mechanic type, and mixed type. This study also discussed the implications of these findings for teaching and learning in science education.

We have analyzed this influence base on survey of central government administration officers and local officers which were taken on 2001 and 2003. Also, we anticipates that this result would help actual field adjustment as well as preparation of speciality of officers. The results are summarized as follows : First, a survey in 2001 shows 68.8 percent of local administration officers answered that their expertise about environmental services were above average. Then, the result was increased to 82 percent of officers responsed that they have more than average expertise and experience in 2003 survey. Secondly, government have to increase effectiveness on regulation or restriction duty. Nonetheless, the survey shows that significant decrease of effectiveness from 2001 to 2003 in both central and local goveniment officers. It means that they spent more effort on local community environmental regulation program other than restriction duty to requisited from central government. Third, moreover, local government do not want to faculty of environmental administration and insists that governments need to set the regulation for particularity of regions.

Objectives : Diffusion tensor imaging (DTl) studies of schizophrenia, thus far, have mainly focused on white matter abnormalities reflected in anisotropy indices such as fractional anisotropy (FA), but recently, new implications of apparent diffusion coefficient (ADC) have been proposed. This is. to our knowledge, the first study to analyze ADC maps of schizophrenic Patients using statistical parametric anatomical mapping (SPAM). Methods : DTl was performed in 20 schizophrenic patients and an equal number of age- and sex-matched healthy controls. ADC maps were then generated, from which 98 volumes of interest were extracted using SPAM. Probability-weighted mean values of ADC were calculated from each volume of interest and compared between the two groups. Results : Significantly higher mean ADC values were observed in patients with schizophrenia compared to healthy controls in the following volumes of interest: bilateral hippocampal formation, bilateral uncus, nght thalamus, light temporal lobe white matter, right superior temporal gyrus, bilateral insula and right lateral ventricle. Conclusion : The results support the recently proposed assertion that regionally increased ADC may reflect cortical brain atrophy. In addition, a new possibility is raised that a neuropathological event involving both the gray and the white matter may also play a role.
