Objective: The aims of this study were to determine the interexaminer reliability and to assess the clinical usefulness of medial plantar nerve (MPN) and lateral dorsal cutaneous branch of sural sensory nerve (LDSN) conduction studies in diabetic patients. Methods: In 26 diabetic patients and 28 healthy adults participated in this study for comparison of MPN and LDSN conduction studies. We analyzed data through the intraclass correlation coefficient (ICC) for inter-examiner reliability evaluation. Results: In diabetic patients, the ICC was 0.963 for lateral dorsal cutaneous branch of sural sensory amplitude (LDSA), 0.958 for medial plantar sensory amplitude (MPA), 0.938 for lateral dorsal cutaneous branch of sural sensory latency (LDSL), 0.877 for medial plantar sensory latency (MPL). The most frequent abnormal electrodiagnostic parameters were the LDSA, and LDSL followed by MPA, MPL. Evaluation of both of these nerves increased the abnormality rate more than 60%. Conclusion: According to our studies, the MPN and LDSN conduction studies are objective and highly reproducible tests. Bilateral nerve conduction study assessment of the MPN and LDSN nerves together increases the rate of diagnosis of early diabetic distal sensory neuropathy compared to assessment of either of these nerve.

지식기반 정보화 사회에서의 교육정보화 환경 변화는 매우 중요한 의미를 가 지고 있으며, 이러한 변화를 능동적으로 수용하기위해서는 정부의 교육정보화 의지와 단위학교별 적극적인 개선 노력이 필요하다. 본 연구에서는 정부가 제시한 교육정보화 사업체계의 원리를 기반으로 단위학교에서 추구해야할 이상적인 정보화 수준을 정량적 지표, 시스템 성숙도 지표, 정보시스템 운영 지표로 나누어 객관적으로 측정 할 수 있는 평가지표 표준안을 개발하여 현실적으로 단위학교에 적용한 결과를 제시하고, 향후 국가 교육정보화 사업계획 및 정책 수립에 기초 자료로 활용코자 한다.

Since the economic system of capitalism is a society established on the basis of efficiency and competition, the class of people either inefficient or falling behind in competition will gradually weed out. Such principles of the market economy will apply, without exception, to the basic nucleus of the distribution system of the agricultural products, and it is evident that the agricultural products wholesale market companies being managed comparatively inefficiently run the risk of weeding out by themselves. At this point of time when the distribution system of agricultural products becomes diversified and large-sized, and differentiated, the relatively inefficients elements of the agricultural products wholesale market companies may most probably endanger the wholesale market companies, the nucleus of the agricultural products distribution system. The producers and intermediary wholesalers being the main customers of the wholesale market companies, the problems resulting from the conflicts of interest between them are very difficult to compromise and it takes a great deal of efforts and time to satisfy the needs of the producers and the intermediary wholesalers. Nevertheless, it is the hard realities that amid such difficulties, the agricultural products wholesale market companies can not neglect to meet the desires of their main customers, the producers and intermediary wholesalers. Since, however, the wholesale market companies are business entities themselves, it is also evident that they will eventually weed out, if they go against the trend of the times wherein all business entities should pursue "customer emotion" beyond "customer satisfaction". It would, therefore, be very opportune to gauge how the producers and intermediary wholesalers, the two main customers of the wholesale market companies evaluate the use of the wholesale market companies, and how satisfied they are with the services offered by the wholesale market companies. At the same time, such research seems to provide the useful basic materials to establish the survival strategies of the wholesale market companies. The examination of the evaluation, by the producers and intermediary wholesalers, the two main customers of the wholesale market companies, of the use of the wholesale market companies shows that both the producers and the intermediary wholesalers have favorably evaluated the items on (1) improvement of the order of business transactions, (2) rationalization of the level of the market rates such as the commission for sale on consignment, loading and unloading charges and bounties (3) impartiality of auctions, (4) level of satisfaction with reliability and diversity of the information of business transactions, (5) efforts of the employees of the wholesale market companies for collection and sales of the goods and (6) level of satisfaction with the services offered by the employees of the wholesale market companies to main customers. At the same time, when asked whether the use of the wholesale market companies improved their business revenues, the producers (25.0%) and intermediary wholesalers (30.0%) evaluated negatively. Such negative results may very likely lead to threatening factors hampering the growth and development of the wholesale market companies. The above negative results may be even more conspicuous especially under the circumstances where the agricultural products distribution system gets diverse and large-sized and differentiated through revitalization of direct transactions between the producers and large-scale discount marts and the competitions among the companies engaged in the same category of industry are very keen. From the viewpoint of the survival strategy of the wholesale market companies, approaches should be so made as the efforts to improve on the earnings of the producers and wholesale market companies may precede. In the evaluation of the payment methods, most of the producers (90.0%) were affirmative, while intermediary wholesalers were negative (35.0%). However, in consideration of the characteristics of the wholesale market companies having the producers and intermediary wholesalers as their customers, it seems that the methods and procedures for the payments should be improved by all means. In particular, if the wholesale market companies should approach this matter from WIN-WIN strategy, it seems that this matter might be resolved more easily. The changes in the environments faced in management activities of enterprises are quickening and at the same time, the growth or weeding out of enterprises is also quickly determined. Amid such changes, the gauging and satisfying of enterprise desires as the survival strategy must be definitely an extremely important element. The wholesale market company being an business entity itself, should be keen to such changes, and needs to make strategic approaches to its customers, if it does not want to weed out amid such changes.

Objective: To investigate the changes of shoulder proprioception in normal subjects, according to the direction of the evoked fatigue on the shoulder muscle group. Method: 20 healthy volunteers (14 males and 6 females, age 20∼35 years) with entirely normal shoulders participated in this study. Before fatigue exercises, the proprioception tests were performed during active reposition (ARP) and passive reposition (PRP) of dominant shoulder, using isokinetic dynamometer, System 3 Pro (Biodex medical system, New York, USA). Three trials each of active and passive repositioning (2°/sec) were recorded. We also estimated the results of the peak torque shoulder movements. The subjects performed maximal efforts with five repetitions on the direction of flexion, abduction, internal rotation and external rotation. The mean values of maximal concentric voluntary contraction (MVC: peak torque of each muscle group contraction) were recorded. We repeated fatigue exercises until the peak torque dropped to 30% three times consistently, then retested the proprioception of shoulder joints. We compared the proprioceptive changes of the shoulder with pre-fatigue test and post-fatigue test on the direction of shoulder movements. Results: There were significant differences of shoulder proprioception between pre-fatigue test and post-fatigue test of ARP in shoulder abduction and external rotation (p< 0.05). Conclusion: In our study, the proprioception of shoulder joint decreased more prominently on external rotation and abduction movements under severely provoked muscle fatigue around the shoulder joint.

Herpes zoster, resulting from reactivation of the dormant zoster virus in the dorsal root ganglion, occasionally causes the peripheral motor weakness. The mechanism of herpes zoster-related radiculopathy is not clear yet. The herpes zoster-related radiculopathy could be diagnosed by the appearance of the motor weakness or radicular pain at the same dermatomal distrubution of vesicular eruptions. But, segmental zoster paresis always does not coincide with the location of the cutaneous eruptions, electrodiagnostic study could be helpful to diagnose atypical heres zoster-related radiculopathies. We report clinical symptoms, signs and electrodiagnostic findings of such atypical radiculopathy related to varicella zoster viral infection, including separation of affected muscles and skin segments.
