This study was focused on improvement of milk production in Mongolia dairy industry by artificial insemination (AI) technology, of which was supported from ODA project of KOICA in Republic of Korea. The study was started from January 2009 to present and 3rd years in this year. So, all data, especially synchronization and pregnancy of dairy cows (Holstein) will be summarized in final result in this year. For synchronization, total 81 dairy cows selected from 4 private farms that were 38, 30, 8 and 5 in Undarmal milk, Onjin (Enkhbayer), Jargalant, and BRM School, respectively. All the dairy cows were injected intramuscular (IM) of 5 ml PGF2α in the vulva and detected estrus 2 to 3 days after PGF2α injection. Total 78 out of 81 dairy cows (96.3%) were detected estrus by only 1 time injection of PGF2α. The dairy cows that were induced estrus, inseminated with 0.5 ml dairy frozen semen by conventional AI techniques. The pregnancy diagnosis of the AI dairy cows was detected by uterus palpation after 60 days of insemination. Total 75 from 78 inseminated dairy cows (90.1%) were diagnosis pregnant. The estrus induction and pregnant rate were very effective using PGF2α injection and conventional AI techniques in Mongolia dairy cow. The results indicated that AI after estrus induction in Mongolia dairy cows could be applied to dairy breeding technology to improve the breeding efficiency and milk production.

This paper proposes the rule-based expert system with auto-turning of PID controller gain and shows the efficiency of fuzzy expert system for the speed control of BLDC motor. The PID controller gain tuned using RZN(refined ZN) formula to initial tuning and fuzzy expert system to subsequent tuning. The fuzzy expert PID control method proposed in this paper results in the reduction of overshoot, the rapid response and the robustness for disturbances and noise.

콘크리트 構造物의 混合모드 龜裂傳播모델(第1報)

This paper attempts to extract the crack tip stress intensity factors and to make a crack propagation model under mixed mode, from the finite element analysis of the concrete structures. In finite element analysis, all elements are initially assumed to be conventional quadratic isoparametric elements and are replaced by 6 node triangular singularity elements in the crack tip zone only. The stress intensity factors and the angle of propagation are carried out by displacement correlation technique and maximum circumferential tensile stress theory respectively. At the first part in a series of two papers, some numerical examples about the concrete SENB and DISK are presented to illustrate the practical effectiveness of the technique.

Objective : The purpose of this study was to assess the effect of job strain on stress and health status among elementary school teachers. Methods and Material : The subjects in this study were 300 teachers who were selected from among 588 teachers in 13 out of 42 elementary schools in the city of Gimhae. Through the questionnaire, demographic characteristics, Karasek's Job Content Questionnaire(JCQ) and the Psychosocial Well-being Index (PWI) to assess their occupational characteristics and psychosocial stress level were surveyed. Medical checkup results of them were adopted to measure their Health status. Results : 24.9 percent of the general teachers were low strain group, and 16.3 percent of them were high strain group. In the senior teachers, 19.7 percent belonged to a low strain group and 21.3 percent belonged to a high strain group. In regard to health status, more senior teachers than junior teachers suffered from obesity(24.6%) and diabetes(11.5%) (p<0.O5), and they also were higher in DBP(p<0.057), total cholesterol(p=0.039) and blood sugar level(p=0.000), the low strain group perceived more social support(p=0.000), and the high strain group felt bigger physical overload(p=0.000). Concerning psychosocial stress, the low strain group was more aware of teacher social role and put more confidence in themselves(p=0.004). The high strain group was more depressed(p=0.001), but no difference was detected in health status. The health status difference between the high strain and low strain groups was significant in depression of psychosocial stress(OR=3.823, 95%CI=1.584-9.224). Conclusion : The senior teachers group was more morbid to obesity, diabetes and hyperlipidemia, which implies that some measure should be studied to help senior teachers manage those diseases properly. The high strain group suffered more from physical overload and was high 'Social support'. Therefore it's required for high strain group to be given more support from colleagues and supervisors, and a stress management program should be implemented to reduce their psychosocial stress.

SLIS(Software License Integrated Solution) is composed of the 6 parts, Server Agent, Web Server, Client Agent, Client Manager, Service, and Install Shield. For the most part of the project is developed based on MFC platform except for the one, Client Manager, which is built on DDK(Driver Development Kit) and ASP. NET platform. Client Agent program installed on a customer's computer is implemented in 14 different classes. Its main function is able to limit and uninstall the purchased software by using teminateProcess. The purchased softwares expiration dates on customer's computer is being monitored by both Server agent and Client software itself. Client Manager hides the process of Client Agent program which shouldn't be killed by manipulating Process List in Kernel through DDK. To do this, Client Manager is internally implanted and registered in Windows Service to be ran as a part of windows system.

This present study was undertaken to observe the effects of pyridostigmine and neostigmine of heart rate and it's antagonistic effect on pancuronium in 62 patients during general anesthesia. We obserived the effect of pyridostigmine and neostigmine with atropine and glycopyrrolate of heart rate, appearance of arrhythmia, time required for returning of spontaneous breath an sustained tetanic response and effect on the amount of secretion in oral cavity and trachea. The result are as follows: 1. The incidence of bradycardia was the highest in the group of atropine and neostigmine i. v. administration together, and the lowest in the group of glycopyrrolate and pyridostigmine i. v. administration together. 2. The incidence of tachycardia was the highest in the group of atropine and pyridostigmine i. v. adminstration together, and the least in the group of glycopyrrolate and pyridostigmine i. v. administration together. 3. Among the experimental cases, only one showed arrhythmia which is PVD. 4. The time required for returning of spontaneous respiration was 4.6-6.1 minutes range in all groups. 5. The group of glycopyrrolate administrated showed the greates antisialogue effect.
