This study was conducted to examine middleㆍhigh school 720 students in seven regions of middleㆍsmall city and town, Myon for 2 months from March 2 through April 30, 2002 in order to realize a side of school health education in middleㆍhigh school and health education need as well as health education specialist in school in the future. The results of this study can be summarized as follows. 1. Health condition is now 'normal' is 51.0%, 'good' is 45.0%, 'not good' is 4.1% and health condition of children is good as much as education level of mother is higher. 2. Experience to learn health education in school for one year recently is 'no' is 39.6%, 'don't know' is 32.6%, 'yes' is 27.8% and it represents health education in school doesn't work well and experience to learn health education is lower and lower in town and Myon. 3. Health education ways to work in school now are 'Movie, Video, Slide' is 40.7%, 'education as groups of nurse-teacher' is 38.6%, 'to distribute health education material and book' is 7.7%, 'education by setting an example' is 3.4%, 'the others' is 9.7%. 4. Time of appropriate health education for one time is 'about a hour' is 56.7%, 'about 30 minute' is 33.8%, 'about two hour' is 7.6%, it represents this situation is because of what students' time is lack and burden about a curriculum in an education administratin and school classed of a focused school score. 5. The average score of satisfaction of health education in school is 16.99±0.58, 'men' is 1.79±0.60, 'women' is 1.61±0.55 as the distinction of sex, satisfaction level of men is higher than women. 6. Learning route about health information is 'through mass media' is 59.9%. 'through family, friend' is 15.0% 'health education lecture' is 7.2%, 'printing media' is 6.1%, 'medical institution' is 5.6%, 'the others' is 5.1%, 'public health center' is 1.0%, 'through mass media' is the highest percent as each 59.1% and 60.6% in all of men and women. 7. The most efficient education way of health education is 'movie, video, slide' is 32.6%, 'health education specialist who works school' is 21.9%, 'school health education by nurse-teacher' is 16.0%, 'way through mass communication' is 11.6%. 8. The appropriate health education specialist in the future is 'health education specialist who has qualifications' is the highest as 64.5%, 'nurse-teacher' is 12.4%, 'medical personnel(doctor, a physician of oriental medicine etc.,)' is 11.0%, 'staff in public health center' is 7.2%, people in other regions(health and medical professor etc.,) is 7.0%, it represents school health education is not actual and is formal now in second hand. 9. The most necessary health education program is 'program of stress solution' is the highest as 24.9%, 'program of no smoking' is 22.7%, 'sexual education program' is 19.8%, 'school violence program' is 8.8%, 'isolate from their friends prevention program' is 8.0%, solution program of stress which gives student by school score was very necessary. Therefore, school health education is formal and inefficient because school education focuses on an entrance exam, so middleㆍhigh school students decrease concern and interest about health education. Furthermore, reliance is gotten down about nurse-teacher who takes charge of school health, a charged person of school health education wants more chargeable health education staff. And a solution program of stress that gives students by school score was very necessary. According to active concern and planned, systematic school health education is necessary to give right health knowledge, health maintenanceㆍpromotion and setting of appropriate health education specialist is very urgent.

새로운 매체현실과 문화변화

Der Begriff "Medienrealita¨t" ist heute aktuell geworden. Obwohl die Medien zur Vemittlung der Kommunikation auch in der Vergangenheit sehr verallgemeinert worden sind, gelten sie heute nicht mehr als bloβes Mittel. Die Entwicklung der elektronischen bzw. technologischen Medien vera¨ndert sowohl die Realita¨t unserer Welt als auch das Sein schlechthin. Der Begriff "Medienrealitat" ist synonym mit den anderen Begriffen wie "digitaler Schein" bzw. "virtuelle Realita¨t". "Informationsgesellschaft", die den tradierten Gegensatz zwischen Sein und Schein. dem Wahren und dem Falschen auflo¨st und zu einer neuen "Form der Realita¨t" avanciert werden. Um die Medienrealita¨t zu analysieren. werden im zweiten Kapitel die verschiedenen Elemente illuminiert, durch die neue Medienrealita¨t und Kultur konstituiert werden: ganz neue "immaterielle Basis der Information. Macht der Bilder, Geschwindigkeit, neue computerielle Wahrnehmung. "Medienwerk". Diese Elemente beherrschen sowohl die Realita¨t als auch die Kultur. Abschlieβend wird die Mo¨glichkeit reflektiert. wie die Kunst (besonders die Literatur) die Medienrealita¨t u¨berwinden und ihre alternativen Wege ero¨ffnen kann. Im dritten Kapitel wird der Begriff "virtuelle Realita¨t" philosopisch uberpruft, wobei er die Gemeinsamkeiten mit den tradierten philosophischen Begriffen wie "dynamis, "potentia, "virtualite"~possibi1ite usw. teilt. Auch kann der Widerspruch der "virtuellen Realita¨t" besta¨tigt werden, die vor allem auf der radikalen Vera¨nderung von Technik. Information und Kapital basiert. Das heiβt: es ist ein Widerspruch oder die Verhu¨llung der ontologischen Implikation, daβ die virtuelle Realita¨t durch die allma¨hliche Negierung ihrer Virtualita¨t zur Realita¨t erhoben wird. Im vierten Kapitel wird das Verha¨ltnis der Gesellschaft zu Umwelt. Information und Medien aus der Sicht der Luhmannschen Systemtheorie betrachtet. Daraus ergibt sich. dass die Gesellschaft als Sozialsystem bei ihrer Selbstreproduktion mit der Leitdifferenz von System/Umwelt operiert und damit die elbstreproduktion der Gesellschaft von der Vera¨nderung ihrer Umwelt (Technik, Bewuβtsein, Organismus usw.) abha¨ngig ist. Dabei ist deutlich, dass Medien (Schrift. Buchdruck. Elektronik usw.). die zur Verbreitung der Informationen dienen, bei der Evolution der Gesellschaft eine entscheidende Rolle gespielt haben. Schlieβlich handelt es sich um die unterschiedlichen soziologischen Theorien u¨ber das Verhaltnis von Medien und Gesellschaft. In den Vordergrund treten dabei die Theorien von D. Bell und M. Poster. Bells Theorie der postindustriellen Gesellschaft behandelt die Entwicklung der Technologie. die heute die Kultur und die Gesellschaftsstruktur stark vera¨ndert. Gegen Bell postuliert Poster eine Wende von der Produktionsweise zur Informationsweise, indem er die erwandtschaft mit der postmodernen Theorie teilt. Seiner Perspektive zufolge gilt heute nicht das Kapital. sondern die Information als Hauptmovens der Gesellschaft. Die Medien ko¨nnen weder das Absolute noch die Utopie sein. Was der Euphorie der sog. "idealen Entwicklung der Medien" kritisch gegenu¨berstehen kann. ist nichts anderes als die kritische Reflexion der Kunst.

상태관측기를 이용한 영구자석 동기전동기의 센서리스 속도제어

손문경,이동희,오석규 진주산업대학교 1999 산업과학기술연구소보 Vol.- No.6

Sensorless PMSM is much studied for the industrial applications and home appliances because a mechanical sensor reduces reliability and increases cost. This paper investigates a field oriented control method without speed and rotor position sensor using the state observer. The observer is based on the model of the motor represented in the stationary two-axes coordinates. The control strategy is to estimate back-EMF by the state observer and to estimate the rotor speed and the rotor position angle from the estimated back-EMF. And we construct back-EMF constant compensator to compensate estimated speed error due to detuned electrical parameter. The observer is tested by simulation and experiment. The results show that the observer gives a good estimation of speed and rotor position, compensated parameter constants. The simulation and experimental results indicate good performances.

장혜진,유희석,임윤경,문세희,장기홍,이정필 대한부인종양 콜포스코피학회 2003 Journal of Gynecologic Oncology Vol.14 No.4

목적 : 재발성 난소암에서 platinum 감수성을 기준으로 2차 항암요법으로 사용한 Carboplatin과 Paclitaxel의 효과를 알아보기 위하여 본 연구를 진행하였다. 연구방법 : 1998년 1월 1일부터 2003년 8월 31일까지 만 5년 8개월 간 아주대학교병원 산부인과에 재발성 난소암으로 입원한 환자 중에서 최초 수술로 난소암을 확진한 후 Cisplatin 또는 Carboplatin 등 platinum 제재가 포함된 항암치료를 받은 후 6개월 이후에 재발한 환자 29명을 대상으로 Carboplatin은 5 AUC를 그리고 Paclitaxel은 175 mg/m^(2)를 투여하였으며, 최소 3회에서 최고 16회까지 투여하였다. 치료효과의 판정은 CT, MRI, Ultrasonography등 영상진단상 암종괴의 크기가 완전히 소실되었을 경우를 완전반응(complete response)으로, 50%이상 감소되었을 경우를 부분반응(partial response)으로, 50% 미만으로 감소되었거나 20% 미만 증가하였을 경우를 불변(stable disease)으로, 그리고 20% 이상 증가되었을 경우를 진행(progressive disease)로 정의하였다. 결과 : 대상 환자에서 완전반응은 6명(21%), 부분반응은 11명(38%), 그리고 불변은 5명(17%)로 전체 반응율 (overall response rate)은 59% 그리고 임상적 유용성(clinical benefit=CR+PR+SD)은 76%이었다. 결론 : 재발성 난소암환자에서 기왕에 사용한 Platinum 제재에 민감한 환자에서는 Carboplatin과 Paclitaxel의 병행 투여가 효과적이었다. Objective : To ascertain the effect of Carboplatin and Paclitaxel combination as a second line regimen for recurrent ovarian carcinoma based on platinum sensitivity. Methods : From January 1st, 1998 through to August 31st, 2003, 29 patients were retrospectively reviewed who had previously underwent primary cytoreductive surgery and adjuvant chemotherapy with Cisplatin or Carboplatin for ovarian carcinoma, and who had later recurred during follow up. All 29 patients had recurred at least 6 months after therapy, and thereafter received second line chemotherapy consisting of Carboplatin (5 AUC) and Paclitaxel (175 mg/㎡) for a minimum of least 3 cycles and a maximum of 16 cycles. Treatment efficacy was assessed by imaging studies including Computerized tomography, Magnetic Resonance Imaging, or Ultrasonography. Complete response was determined as complete disappearance of tumor, partial response at least than 50% reduction in tumor volume, stable disease as less than 50% reduction or less than 20% increase in tumor volume, and progressive disease as more than 20% increase. Results : There was complete response in 6 (21%) patients, partial response in 11 (38%), stable disease in 5 (17%), showing an overall response rate of 59%. The clinical benefit (CR+PR+SD) was 76%. Conclusion : The combination of Carboplatin and Paclitaxel administration seems to be an effective mode of second line therapy in patients with recurrent ovarian carcinoma who had been sensitive to prior platinum based chemotherapy.
