This paper explains the study of controller design applied to SRM(Switched Reluctance Motor) concept. This controller executes controller algorithms via ${\mu}$-processor to increase stability and precise measurement, and VHDL (Very high speed integrated circuit Hardware Description Language) is designed to generate SRM driving signal. During initial period, SRM controller was designed to control .respective target RPM (Revolution per minutes) and PR (Proportional Integral Differential) coming from the PC(Personal Computer) monitor program, and receiving clockwise and counter-clockwise rotation signal and target RPM coming from the front panel, and receiving the location of rotational element and RPM generating from the position censor during activation period.

This study was carried out to evaluate on the job implementation of ITEC(Invention Teacher Education Center)'s in-service teacher training. To accomplish this purpose, teacher's perception on retention, usefulness, utilization, and enhancement were investigated after one year completing in-service teacher training. The populations of this study were 60 teachers completing in-service teacher training of the southeast ITEC. The methods of this study were survey research and qualitative content analysis. The subjects of survey research were 30 teachers and the case analysis objects were 12 epilogues of in-service teacher training. The mean of job implementation of southeast ITEC's in-service teacher training was 4.07 on a five-point scale. Teacher's perception on job implementation sub factors after one year completing in-service teacher training were as follows. The mean of enhancement factor was 4.39, usefulness factor was 4.11, utilization factor was 3.94, and retention factor was 3.82 on a five-point scale. The mean of enhancement factor and usefulness factor were relatively high level as compared with the mean of job implementation and the mean of utilization factor and retention factor were relatively low level as compared with the mean of job implementation. The results of qualitative content analysis about 12 epilogues of in-service teacher training, some significant instances were deducted that representable retention, usefulness, utilization, and enhancement factors directly and indirectly.

Background: There are various conservative treatment options for lateral epicondylitis (LE). The aim is to evaluate pain, daily functioning, and complications after ultrasound-standardized autologous blood injections in patients with LE. Methods: For this prospective cohort study, consecutive patients (>18 years) diagnosed with LE were included. Autologous blood was injected using a medical device containing an injection disposable with 12 small needles (Instant Tennis Elbow Cure [ITEC]) device. Patient-Rated Tennis Elbow Evaluation (PRTEE), subjective elbow score (SES), palpation and provocation pain, satisfaction, and complications of treatment were measured at baseline and two months after treatment. Paired t-tests and Fisher's exact tests were used for calculating the difference between pre- and post-treatment outcomes. Results: Fifty-five elbows were analyzed. Mean time between pre- and post-treatment was 11.1 weeks (standard deviation [SD], 8.9 weeks). The mean PRTEE score decreased from 68.2 (SD, 15.7) before surgery to 53.2 (SD, 25.9; p<0.001) after. The mean SES improved from 36.9 (SD, 20.8) to 51.7 (SD, 27.4; p<0.001). Despite this improvement, only 44.7% of patients showed relevant clinical improvement in PRTEE, and 37.3% showed significant clinical improvement based on SES. Four patients reported a complication and the injection disposable failed three times. Conclusions: Ultrasound-standardized autologous blood injection using the ITEC device is not an effective tool in reducing symptoms related to LE. This study showed that only half of all patients experienced a positive effect. In this heterogeneous cohort of patients, we showed no added value of ultrasound standardization.

본지에서는 이번호부터 일본의 의료제도와 병원경영에 대한 연재를 시작하고자 한다. 일본의 의료제도나 병원운영에 대하여 잘 알려진 것 같으나 막상 그 실체에 대하여 정확한 지식이 부족한 실정에서 우리나라의 의료에 직.간접으로 많은 영향을 주고 있는 일본의 의료제도의 전반에 대한 소개와 함께 현장에서 접한 일본병원계의 실상에 대한 상세한 정보는 우리 병원계에도 많은 참고가 되리라 믿는다. 연재를 맡아줄 남상요교수는 연세대학교 보건대학원을 졸업하고 1988년 도일하여 1993년 일본동경대학교에서 보건학 박사학위를 마친 후 동경대학교 보건관리 학교실 객원 연구원, 병원 종합컨설팅회사인 일본ITEC(주)연구원을 거쳐 1994년 귀국하여 현재 유한전문대학 의무행정과 교수로 재직하고 있다. 전공은 병원행정으로써 약 6년간 일본생활 중 일본 전국의 병원 및 의료관련 기관들을 방문하여 병원 운영에 관한 조사와 컨설팅업무에도 관여하였다. 의료료란 결국 한나라의 문화의 반영이라는 관점에서 직접 일본에서 생활하면서 느꼈던 의료를 포함한 사회,문화에 관한 기술은 독자 여러분의 흥미와 더불어 유익한 정보를 제공해 주리라 믿는다

This study empirically investigated cultural differences in the amount of information provided by managerial accounting information systems as well as the differences in organizational performance according to variations in the amount of information. Through cluster analysis, I classified sample firms into five organizational cultural types: Semi-innovative, innovative, bureaucratic, semi-bureaucratic and supportive. The results showed that in the semi-innovative firms, a greater amount of the traditional and advanced types of information is produced, while in bureaucratic firms, traditional information is much more provided than in the innovative, semi-bureaucratic and supportive firms. These results confirmed cultural differences in the amount of information produced. According to the results of this study, it was found that in organizational performance, the rankings of semi-innovative firms, which have the highest scores in the amount of information, are also the highest, and the performance scores in innovative firms are generally next to those of semi-innovative firms. Hence it is concluded that there are cultural differences in the amount of information provided and theses differences affect organizational performance

Supplying stable electric power is one of the important objectives of the Official Development Assistance (ODA) because it is strongly related with improving living standards and income levels in the region. However, rural areas in many developing countries are not properly connected to national power grids, and even areas connected to national power grids are frequently blacked out due to limitations in power capacity. These lack of electric power is a major obstacle to improving income levels and improving living standards in those areas. The Korea-Tanzania Innovative and Energy Center (iTEC), which was established by Seoul National University in cooperation with the Nelson-Mandela Africa Institute of Science and Technology and Technology (NM-AIST) try to build a small solar power plant using a smart-off grid in rural area of Tanzania, where there is no electricity. 10 kW and 7 kW solar power plants are built in Mkalama Village in Kilimanajaro Region and Ngurdoto Village in Arusha Region to provide power to about 50 households each. In addition, smart monitoring systems were installed to collect data about status of power system and power consumption of each house. iTEC seeks for sustainable improvement the income level and quality of life of rural residents in developing countries through the construction of small solar power plants using smart-off grid, and the implementation of various connected projects.
