Dysplasia-associated seizure disorders are markedly resistant to pharmacological intervention. Relatively little research has been conducted studying the effects of antiepileptic drugs(AEDs) on seizure activity in a rat model of dysplasia. We have used rats exposed to methylazoxymethanol acetate(MAM) in utero, an animal model featuring nodular heterotopia, to investigate the effects of AEDs in the dysplastic brain. Pilocarpine was used to induce acute seizure in MAM-exposed and age-matched vehicle-injucted control animals. Field potential recordings were used to monitor amplitude and numbers population spikes, and paired pulse inhibition in response to stimulation of commissural pathway. Two commonly used AEDs were tested: diazepam 5, 2.5mg/kg;phenytoin 40, 60mg/kg. Diazepam(DZP) and phenytoin(PHT) reduced the amplitude of population spike in control and MAM-exposed rats. However, the amplitude of population spike was nearly eliminated in control rats as compared to the MAM-exposed rats. Pharmaco-resistance was tested by measuring seizure latencies in awake rats after pilocarpine administration(320mg/kg, i.p.) with and without pretreatment with AEDs. Pre-treatment with PHT 60 mg prolonged seizure latency in control rats, but not in MAM-exposed animals. The main findings of this study are that acute seizures initiated in MAM-exposed rats are relatively resistant to standard AEDs assessed in vivo. These data suggest that animal model with cortical dysplasia can be used to screen the effects of potential AEDs.

본 연구는 정하중하에서 최대하중과 변형을 이용하여 구한 변형강도(K_(D))로부터 아스팔트 콘크리트의 소성변형 계수의 추정 가능성을 보여준다. 이 논문은 새로운 강도특성치인 K_(D)를 개발하는 김테스트 연구의 일부로 최근 2, 3단계의 연구결과이다. 19mm 편마암과 화강암 2가지 골재와 3가지 폴리머로 제조한 7가지 바인더로 같은 입도에서 소성변형 저항성이 다른 14가지 혼합물을 만들었다. 3단계에선 슬래브 공시체(30cm x 30cm x 6cm)를 제조후 반으로 나누어 한쪽 공시체에선 두 개의 김테스트 공시체 코어를 뜨고 다른 한쪽으로는 60℃ 반복주행(WT)시험을 수행하였다. 한편 2단계에선 슬래브 공시체의 가운데에서 WT 시험을 수행하고 그 양옆에서 김테스트 공시체 코어를 채취하였다. 4가지 하중봉을 사용하여 60℃에서 김 테스트를 수행하였다. 침하깊이-반복회수 곡선으로부터 최종 침하 깊이와 동적안정도 두 가지 소성변형 계수를 각 혼합물별로 구했다. 각 하중봉과 골재 별로 K_(D)와 소성변형 계수간의 통계적 상관관계 분석을 수행한 결과 K_(D)와 소성변형 계수와의 결정계수가 매우 높게(R² > 0.9) 나타났다. 그러므로 K_(D)는 소성변형 계수를 추정하는데 있어 매우 적합한 특성치이며 4cm 직경에 1cm 반경으로 원형절삭한 하중봉이 R² 가장 높게 나타나는 하중봉임을 알 수 있었다. 따라서 김테스트는 향후 소성변형을 추정하기 위한 표준화된 특성치로 사용할 수 있도록 더 연구 개발을 할 수 있을 것으로 판단되었다. This study shows predictability of rut parameters of asphalt concrete based on the deformation strength (K_(D)) which is obtained from the maximum load, deformation and size variables of loading head under simple static loading. This paper is the result of latest studies, phases 2 and 3, which are parts of Kim Test study for developing a new strength property, K_(D), for asphalt concrete. Two aggregates, gneiss and granite, with maximum size of 19mm and seven binders using three polymers(LDPE, SBS, SBR) were used to produce 14 different natures of rut resistance mixtures using the same gradation. A slab(30m x 30cm x 6m) was cut into two pieces and 2 cores for Kim test were taken from a half piece and the other piece was used for wheel tracking (WT) test at 60℃ in phase 3. In phase 2, WT test had been carried out in the middle of a whole slab and cores were taken from both sides of the wheel path along the center line. Kim test was performed using four loading heads at 60℃. Two rut parameters, depth of rut and dynamic stability, from the rut depth-cycle curve from a WT test were obtained for each mixture. Statistical analysis were performed for each loading head and aggregate to find out correlation between K_(D) values and each rut parameter. The analysis result showed that K_(D) had very high coefficient of determination (R² > 0.9) on the average with rut parameters. It was found that K_(D) is a good property that has excellent predictability for rut parameter of asphalt concretes, and the 4cm diameter loading head with 1cm curvature radius gave the best result in R². Therefore, Kim test can be further developed as a standard property for use in rut performance estimation of asphalt concretes.

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.

Purpose: The purpose of this study was to identify the needs of health education in students, their parents and teachers in the elementary, middle and high schools and the current situation of health education class. Method: The subjects of this study were a total of 9450 persons including students, their parents and teachers from 279 schools throughout the country. They were selected through convenient sampling. Data were analyzed through x^(2)­test and ANOVA. Result: Students, their parents and teachers replied that 18 dimensions of health education class (DHEC) are necessary. The four DHEC - healthier life style, sex education, mental health and safety education - showed high educational needs in students, their parents, and teacher. High school students had higher educational need of 'symptom management for daily living' than elementary and middle school students. Students, their parents and teachers in elementary school had higher educational needs of 17 DHEC that those in middle and high school. The percentages of schools with health education class taught by health teachers were 99.2%, 75.5% and 66.0% respectively in elementary, middle and high schools. Health education was given mainly using physical education classes at elementary schools, and creative class hours at middle and high schools. In general, health education took 1-3 hours per week at elementary schools, and less than an hour at middle and high schools. Conclusion: Therefore, based on the results, systematic health education class should begin from elementary school to meet the need of health education in students, their parents and teachers, and further study should be made on the number of hours required and the amount of contents of 18 DHEC.
