This paper presents a implementation of digital sensorless position control system of surface permanent-magnet synchronous motor (SPMSM) drive with a direct torque control (DTC). The system are stator flux and torque observer of stator flux feedback control model that inputs are current and voltage sensing of motor terminal with estimated rotor angle for a low speed operating area, two hysteresis band controllers, an optimal switching look-up table, rotor speed estimator, and IGBT voltage source inverter by using fully integrated control software. The developed sensorless control system are shown a good motion control response characteristic results and high performance features using 1.0 [kW] purposed servo drive SPMSM.

하수 및 폐수 내 고농도의 인 및 부유물질 제어를 위해 개발한 일체형 완속교반/침전 그물망 압착식 섬유여과시스템을 이용하여 하수처리장의 반류수 내 부유성 고형물 및 인 처리에 적용했을 경우에 따른 성능을 검토하고자 하였다. 6가지 Mode로 실험을 하였으며, 16.7, 33.3, 41.7 및 50.0 ton/day 유량과 Al/P 몰비 2~4의 조건에서 실험을 행하였다. 응집제를 주입하였을 경우에 모두 높은 총인(T-P) 제거 효율을 보였지만 연속운전시간이 7.8 min~11.4 min으로 짧아지는 단점이 생겼다. 이를 극복하기 위해 일체형 완속교반/침전 그물망 압착식 섬유여과시스템을 응집/급속교반/공기주입/완속교반/침전공정 및 여과공정으로 진행 시 연속운전시간이 88.2 min으로 다른 모드로 운전한 결과에 비해 8~11.3배 정도 증가하였다. 역세수량율도 5.4%로 매우 낮게 나타남에 따라 이 공정이 가장 효율적인 처리방안으로 평가되었다. An integrated slow mixing/sedimentation and net fit fiber filtration system has been developed to reduce the high concentrations of suspended solid (SS) and total phosphorus (T-P) in the reject water from sewage/wastewater. A filtration device used in this experiment consists of coagulation, in-line mixing, air injection, slow mixing/sedimen-tation, and filtration processes. The performance test using this device was carried out with six operational modes for reject water from sewage treatment plant. Experimental conditions used were 16.7, 33.3, 41.7 and 50.0 ton/day of flow rate and 2~4 of Al/P molar ratio. By injection of coagulant in each operational mode, the high removal efficiencies of SS and T-P were obtained, but continuous operation time was decreased to 7.8~11.4 min in most modes. However, when the Mode 5 of the developed filtration device was applied, the continuous operation time was maintained up to 88.2 min. Also, it was found that the continuous operation time in the Mode 5 using the developed system was increased from 8 to 11.3 times longer than those in other modes. Backwashing flow rate was also very low at 5.4% of total filtered water. Therefore, it can be concluded that the Mode 5 of the developed filtration system was the most efficient treatment method for the removal of high concentrations of SS and T-P.

Lots of large sized hospitals have already installed medical informations computing system. However, legislator and government have not made any policies and legislations for regulating and protecting privacy about personal medical informations. Of course, there are statues of privacy rule for protection of personal informations. If a term of medical informations is included in a term of personal informations broadly, present privacy rule could regulate use or disclosure of medical informations for privacy protection. But, medical informations are very sensitive informations compared with other personal informations. Therefore, the special privacy rule for regulating about protection of personal medical informations has to make as soon as possible. On this article, I suggest a appropriate direction for legislation about protection of personal medical informations according to analyzing into U.S.A.'s statute for privacy act about personal medical informations - "Health Insurance Portability and Accountability Act".
서영해는 1945년 8월 15일 프랑스 파리에서 해방을 맞이하였다. 그는 프랑스 언론을 통해 한국독립운동이 가지는 역사적 당위성과 장차 한국이 수행해야 할 역할과 사명을 알렸다. 그동안 한국의 독립운동에 대해 후원을 해준 프랑스 인사들에게도 감사의 인사를 전했다. 중국 중경에 있는 임시정부와도 연락을 주고받으며 활동을 모색하였다. 서영해는 1947년 5월 국내로 환국하였다. 그는 학계·언론계·정계를 넘나들며 다양한 활동을 전개해 나갔다. 우리 실정에 맞는 프랑스어 교재 제작에 나서 두 권의 책을 발행하였고, 이를 바탕으로 대학에서 후학양성에 힘썼다. 또 각종 신문 관계 행사에 참석하여 강연을 펼쳤다. 서영해는 임시정부와도 지속적인 협력·협조 관계를 이어갔다. 임시정부가 자주적 통일정부 수립운동을 추진하자, 이에 적극적으로 참여하였다. 임시정부 요인들과 UN한국임시위원단 파견에 따른 향후 대책과 추진 방향을 논의하였고, 국외 인사들과 만남에서 ‘가교'역할을 수행하였다. 또한 임시정부에서 ‘자주독립국가 건설'이라는 우리 민족의 정확한 의사를 국제사회에 알리기 위해 1948년 9월 21일 파리에서 개최되는 UN총회 파견을 추진하자, 선발대의 임무를 맡았다. 중국에서 발생한 여권 문제로 인해 UN총회에는 참석하지 못했지만, 프랑스 외무부 아시아-대양주국장을 만나 한국과 프랑스의 협력 관계 구축을 위해 힘썼다. Seo Young-hae went through Korea's liberation in Paris, France on August 15th, 1945. He had a strong presence in the French press and let people know the historical justification of Korean independence movement and Korea's role and mission to play in the future through the press. He delivered his gratitude to French figures who supported Korea's independence movement. He also looked for activities through communicating with the Provisional Government of the Republic of Korea located in Chongqing, China. He returned to his home country, Korea in May, 1947. He had done a variety of activities across academic, political and media sectors. He published two French textbooks according to the situation at that time and devoted himself to nurturing younger generation at university. He gave lectures at events related with newspapers and taught students at his private office. He continued to have a close cooperative relationship with the Provisional Government of the Republic of Korea afterwards. He strongly endorsed the movement of the Provisional Government of the Republic of Korea in terms of establishing an unified government. He also strived to discuss future measures and directions with other leading figures of the Provisional Government of the Republic of Korea when UN dispatched the temporary commission on Korea and also acted as a bridge in mediating with key figures from abroad. He came in on a dispatch party when the Provisional Government of the Republic of Korea tried to announce a strong will of our nation for establishing an autonomous government at UN General Assembly held in Paris on September 21st, 1948. The entry procedure problem in China disturbed him on his mission in attending the UN General Assembly but he still strived to construct a cooperative relationship between Korea and France by having a meeting with a chief of the Asia-Pacific Affairs Bureau from Department of Foreign Affairs of France.

Following the constitutional and political reforms that have marked the last decade in Central and Eastern Europe, the time has new come for the whole-scale reform of public administration. Here a summary is given of the main changes that have occurred in administrative law during the period 1996~1997. Especially it changes to general code of procedure and to the judicial system insofar as they relate to administrative supervision. The focus is on the major judicial decisions concerning administrative law. This article covers relevant decisions of the constitutional courts as well as the administrative or civil courts. Main goals in this article are twofold; one is to give a snapshot of the administrative law system of each country; the other is to record the main changes and developments that have occured in each country. Conclusionally the writer has tried to find how other countries not influenced under Germany or French administrative law system have established their administrative judicial system. Through making reference to this analysis, the writer has suggested what is the right way which Korean administrative judicial system should be improved.
