The department of future farmers were established in 10 agricultural high schools in 1980, in order to provide the students with Intensive programs leading to future farmers. This study was carried out to check the effectiveness of education in the department of future farmers and to define the related factors affecting on effectiveness. Data were collected from the 430 students of the ten departments of future farmers through questionnaire. Effectiveness was measured by comparison with the opinions of the students when they began the high school life and when they almost finished their educational programs. The results of the study were as follows; 1) In the two agricultural high schools, the students who wanted to become farmers when they graduated from the ag. high schools were less than those when they began their high school lift. But in the three ag. high schools, the students who wanted to become farmers when they almost finished programs were more than those when they began their school life. 2) In three schools which the number of students wanted to become farmers increased during high school period, students had more positive attitude toward the school life, more practical educational programs for farming, and more desirable home environments necessary to become a farmer. 3) In order to fostering future farmers in agricultural high school, school should recruit the students who want to become farmers and have them to participate in rich and various educational programs for developing the farming abilities.

The purposes of this study were to investigate the therapeutic effects of an early exercise program after mastectomy and to provide the early exercise program protocol for patients who had undergone mastectomy. The subjects were seventy women who were diagnosed with breast cancer. They were randomly assigned either to a experimental group (n=35) that received early postoperative exercise program or to a control group (n=35) that received only education by nurses. Data were obtained for each patient from goniometric measurements of shoulder flexion, abduction, external rotation, 10 elements of functional performance, and subjective pain evaluation using visual analogue scale (VAS). All variables were measured preoperatively, three days postoperatively, and one month postoperatively. Data were compared by groups using independent t-test and Mann-Whitey U test for parametric or non-parametric data, respectively. There were no significant differences between the groups for all variables preoperatively and at three days postoperatively. But there were significant differences at one month postoperatively. The experimental group showed a statisti-cally significant increases in shoulder flexion, abduction, and external rotation and in the pain VAS at one month Postoperatively (p〈,05). Also, at one month prostoperatively, the experimental group had less difficulty with three elements of functional performance-doing up a 'back' zippered article of clothing, reaching the ipsilateral scaula, and contralateral scapula with the fingers on the operated side- than the control group (p〈.05). The results of this study suggest that after mastectomy, the early exercise program conducted by a well-trained physical therapist can make a significant contribution to the return of more normal shoulder function and activities of daily living and to an increased quality of life.

Background: The behavior of cancer can be very varied with different individual responses to chemotherapy. Individualization is crucial to the optimization of chemotherapy. The individualized chemotherapy sensitivity test has been introduced to help in the selection of the appropriate drug for each individual patient but disappointing results achieved with old chemosensitivity tests. The development of the adenosine triphosphate based chemotherapy response assay(ATP-CRA) was designed to overcome the limitations of many in vitro chemotherapy sensitivity tests. The aims of this study were to predict accurately the ATP-CRA and a patient's clinical response to chemotherapy(CT(carboplatin, paclitaxel), PT(cisplatin, paclitaxel)) in epithelial ovarian cancer and to assess the clinical efficacy of the ATP-CRA. Materials and Methods: The study was performed on 34 patients who is diagnosed initially the epithelial ovarian cancer for chemotherapy after operation at Gospel hospital of Kosin university between March 2005 and December 2007. The ATP-CRA was evaluated the chemosensitivities of nine anticancer drugs for epithelial ovarian cancer. To investigate the correlation between ATP-CRA and clinical outcomes in patients with epithelial ovarian cancer, it was compared the clinical responses with the results of CSA retrospectively. Statistical analysis was performed using the Fisher's exact test. Results: The mean chemosensitivity index(CI) tested by the ATP-CRA, were 186.4(carboplatin), 167.9(cisplatin) and 194.1(paclitaxel) respectively. The Cisplatin showed the most effective effect. The sensitivity and specificity of ATP-CRA were 96.4% and 50.0%. The positive and negative response prediction values were 90.0% and 75.0%. The accuracy rate was 88.2%. There was a significant relationship between the results of ATP-CRA and clinical responses(p=0.04). Conclusions: This study shows that ATP-CRA could be used clinically to predict chemoresponse in epithelial ovarian cancer. However, prospective randomized clinical trials in a larger patient cohort are warranted to confirm the clinical correlation of ATP-CRA.

Background: Chemotherapy-induced nausea and vomiting (CINV) are major adverse effects of cancer chemotherapy. The serotonin [5-hydroxytriptamine-3 (5-HT3)] receptor antagonists (RAs)(ondansetron) significantly advanced antiemetic therapy for cancer patients, but despite treatment with a 5-HT3 RA plus a corticosteroid according to published guidelines. The 5-HT3 RAs prevent vomiting in the first 24 hour after chemotherapy when coadministered with steroids but they appear to lack efficacy in the delayed phase. We compared the impact of acute (during the first 24 hours postchemotherapy) and delayed (days 2 through 5 postchemotherapy) CINV on patients of an aprepitant regimen with an ondansetron regimen, for antiemetic efficacy after highly emetogenic chemotherapy (HEC). Materials and Methods: The study was performed prospective on 61 patients who is diagnosed initially the gynecological cancer during chemotherapy at Gospel hospital of Kosin university between March 2007 and October 2007. The study was divided according to an aprepitant regimen use 30 patients and an ondansetron regimen 31 patients. The efficacy of controlling acute/delayed nausea, vomiting and adverse effects were compared. Statistical analysis was performed using the chi-square test. Results: The efficacy of controlling nausea with an aprepitant regimen and an ondansetron regimen was 86.7%, 83.9% in acute periods and 99%, 83.9% in delayed periods respectively. The efficacy of controlling vomiting with an aprepitant regimen and an ondansetron regimen was 93.3%, 90.3% in acute periods and 96.7%, 83.9% in delayed periods respectively. The efficacy of controlling delayed vomiting with an aprepitant regimen reported significantly(p value=0.034). The common adverse effects in both groups were not statistical significantly in incidence and severity. Conclusions: The regimen including aprepitant was superior in preventing CINV as compared with a regimen in which both ondansetron and dexamethasone were given delayed periods in patients receiving chemotherapy.

대부분의 신경망 시뮬레이션 프로그램은 기존의 언어(C,PASCAL,FORTRAN등)로 구현되었다. 기존의 언어들은 신경망구조와 신경망의 동적행위를 제어하는 데 적합한 자료구조와 문장들을 가지고 있지 않기 때문에 시뮬레이션 프로그램을 작성하거나 모델의 변경에 어려움이 많다. 본 논문에서는 신경망 시뮬레이션 프로그램을 작성하는데 적합한 언어를 설계하였다. 특히 제안된 언어는 신경망 구조를 쉽게 표현할 수 있고 신경망의 동작행위를 효율적으로 기술하기 위하여 층마크로 정의 개념을 도입하였다. 언어는 두개의 DIVISION으로 구성되었다. 하나는 망구조를 기술하기 위한 NETWORK STRUCTURE DIVISION이고 다른 하나는 신경망의 행위를 제어하는 PROCEDURE DIVISION이다. Most of neural network simulation programs have been implemented with the conventional computer languages. It is difficult to implement simulation programs and is various to build neural network, because the languages have not data structures and statements suitable for expressing neural network structures and controlling neural behaviors. This paper describes a neural network simulation language, specifically designed for the development and modeling of neural network applications. It has a layer macro definition concept to express the arbitrary network structures and dynamic neural behaviors easily. It consists of the two divisions. First division describes the network structures. Second division controls the network behaviors.

Background : The reported incidence of early gastric cancer located in the upper portion of the stomach has been increasing with the recent advances in its diagnosis and screening. Recently, we have successfully performed laparoscopic assisted proximal gastrectomy and gastric tube reconstruction without pyloroplasty on three patients with early gastric carcinoma localized to the upper third of the stomach. We describe our modification of this procedure in this report. Method : After creating an surgical pneumoperitoneum, the stomach was mobilized using laparoscopic coagulating shears. Upper half of the greater curvature and three-quarters of the lesser curvature were then dissected along with regoinal D2 lymphadenectomy. This was followed by a 5 cm, longitudinal mini-laparotomy in the upper abdomen, and the construction of the exteriorized stomach with a gastric tube measuring 20 cm long and 4 cm wide. Reconstruction with an esophagogastrostomy was performed using a circular stapler. Result : No post-operative morbidity or mortality was observed in this small series of patients. The average operative time was 250 minutes (range 220-300 minutes), and the average blood loss was 150 ml (range 90-180 ml). The mean number of lymph nodes harvested during these laparoscopic proximal gastrectomies was 24 nodes (range 22-25 lymph nodes). The average postoperative hospital stays was 7.5 days (range 7-8 days). Conclusion : Our technique of laparoscopic assisted proximal gastrectomy and gastric tube reconstruction without phloroplasty offers a minimally invasive technique with the potential of impoving the post-operative quality of life patients with an early-stage proximal gastric cancer.
