We have visited the asylums in Chollapukdo for two months since March of 1985. We conducted a comparative study between the patients who has been previously hospitalized and who has not been hospitalized for psychiatric problems. We individually interviewed 489 patients using the interview schedule. The results are shown as follows: 1. The group who were young, single and highly educated have been more hospitalized than the groups who were old, married and little educated. However, no significant difference was made by sex and districts. 2. The group who lived alone or were deserted from the family has been rarely hospitalized. 3. The group, who has been entered the asylum by the family or who explained the reason as treatment, has been more hospitalized previously than the group entered by the others or who said that they came due to alcohol. 4. While the group who has been hospitalized showed tendency to accept having their psychiatric disorders, but the group who has not been hospitalized showed tendency to deny having their disorders. 5. The group who named their disorders psychoses or schizophrenia has been more hospitalized than the group who named them alcoholics. 6. The group hospitalized previously has been also treated in other ways besides psychiatric treatment, and chronic patients with the duration of more than three years has been relatively hospitalized previously. 7. While the group who has been previously hospitalized was relatively indicated for hospitalization, but the other group was not relatively indicated.

Background : Recently, the lung cancer mortality rank first in Korea. The prognosis of lung cancer is not good enough with current treatments and multimodality treatments are required. So we are interested in the characteristics of lung cancer patients for better treatment. Methods : We searched lung cancer patients since 1994. Then we collected the data of primary lung cancer patients about the demographic features, histologic types and diagnotic methods. We divided the total period into 2 haves and specific analysis was tried. Results : 1) Total 850 patients were included. 633 (74.5%) were male and 217 (25.5%) were female. 2) The mean age was 65 ± 11 years old. and the peak age was 7th decades. 3) Squamous cell carcinoma(334/850, 39.3%) was slightly more prevalent than adenocarcinoma(302/850, 35.5%). Conclusion : From these results, we expected that older persons will be diagnosed to have lung cancer and adenocarcinoma will be more dominant histologic type with time.

Background: The current treatments of acute myocardial infarct(AMI) Include noninvasive method using thrombolytics and invasive methods such as primary percutaneous transluminal coronary angioplasty(PTCA) and coronary artery bypass graft(CABG)surgery. Although there are many studies comparing the effectiveness of noninvasive and invasive methods, when large clinical centers, 20% of totar hospitals, were excluded, most middle-sized hospitals lacked personnels and facilities for the invasive methods. Thus they opted for the noninvasive methods. Therefore, in this study, the clinical characteristics of AMI patients and the results of thrombolytic & conservative treatment were observed. Method: 137 patients with acute myocardial infarct, who visited KonKuk University Medical Center, ChoongJu Hospital during Sept. 1990 to Sept. 1999 were analysed retrospectively using medical records. Result: The sexual compositions of patients were 63.5% male, and 36.5% female. The mean age for male patients were 56±12.9, and for female patients 68.7±9.6 (p<0.05). The mean age for female patients was significantly older than male patients. The patients in the thrombolytic treatment group had mortality rate of 6.25% which is lower than that of the conservative treatment group at 12% (p>0.05). Conclusion: Although in our study, small number of acute myocardial infarct patients caused the statistical insignificance, rapid revascularization by thrombolytic therapy within 6 hours of onset of symptoms improved mortality rate and early ambulation. And we had good results on AMI with thrombolytic agent in ChungJu including near rural area as primary emergency hospital. Therefore a prospective research with greater number of subjects is needed to develop better treatments for AMI.

We examined 1,856 patients who visited Won Kwang Neuropsychiatric hospital since July 11 of 1984(since the hospital opened) until June 11 of 1986. We researched diagnostic and other distributions of inpatients and outpatients. The study revealed as follows : 1. Of total patients males visited this hospital more than females as 52.7%. Most of them(67.1 %) resided in Iri, Iksan and Kimje. In the point of insurance, insured patients and uninsured patients except medicaids were 73 %. Males(60%) were more insured medically than females (55.4%). While insured patients relatively resided in urban area, but uninsured patients except medicaids did in rural area. 2. Of outpatients neurotic disorder was the most as 35.1%, secondly schizophrenic disorder and thirdly affective disorder, but of inpatients schizophrenic disorder was the most as 41.4%, secondly neurotic disorder thirdly affective disorder. 3. Alcohol abuse (98.2 %), paranoid disorder, convulsive disorder and child mental disorder were mostly found in males, but neurotic disorder (59 .6 %), affective disorder and other psychotic disorder were mostly found in females. 4. In unmarried ones schizophrenic disorder ( 43 .6 %), neurotic disorder, other psychotic disorder were common, but in married ones neurotic disorder (55.1 %), schizophrenic disorder, affective disorder were common. 5. On the distribution of age schizophrenic disorder was found the most in the twenties (28.4 %), next in the thirties and in the forties, but neurotic disorder was found the most in the thirties, next in the twenties and in the forties. 6. On the distribution of age at onset schizophrenic disorder develops mostly during the twenties (45.5 %), secondly during the teens and thirdly during the thirties, but neurotic disorder develops mostly during the thirties and the twenties (53.1 %). 7. On the duration of hospitalization 34.4% of the patients was hospitalized during less than 15 days, 22.0% during 60-90 days and 80.4% during less than 3 months. 8. In the result of treatment 41.2% of the patients was improved and 31.7% a little improved. In total 72.9% of the patients got helped therapeutically.

CORBA 기반의 Application Service System을 위한 부하 공유 서비스의 설계 및 구현

임주혁,박세명,강흥식 인제대학교 2001 仁濟論叢 Vol.16 No.1

근간 분산된 객체에 대한 부하분산의 목적으로 OMG의 CORBA를 많이 이용하고 있지만 CORBA의 일반적인 기본 서비스는 특정 시스템에서 최적의 기능을 발휘하지 못한다. 이에 본 논문에서는 화상 회의를 하는 특정 시스템의 분산된 이미지 처리 객체(IPO)에 대해 CORBA를 기반으로 하여 어떻게 작업 반환 시간을 최소화 할 수 있는가에 대한 방법을 제시하였다. 이는 동일한 처리를 하는 IPO가 여러 개 존재할 경우 어떤 IPO를 선택하여 이미지 처리를 시키는 것이 가장 적합한지에 대한 것이다. 즉, Client의 이미지 처리 요청이 있을 때 Object Manager는 작업 반환 시간을 최소화 할 수 있는 IPO를 선택하여 작업을 의뢰하기 위해 Object Manager는 IPO가 탑재된 머신의 하드웨어적 성능, 실행되고 있는 IPO의 개수, 해당 IPO가 현재 처리 가능한지의 여부 그리고 처리할 이미지와 처리 후의 이미지의 크기를 고려하여 최적의 성능을 낼 수 있는 IPO를 선택하였다. 결과적으로, IPO의 상태를 고려한 경우가 CORBA의 기본 기능만을 사용한 경우보다 작업 반환 시간에 대해 9∼22% 정도 성능이 개선되었다. Recently, CORBA by OMG is widely adopted as a middleware for constructing distributed object system, but the basic services on CORBA do not appropriate for the operations on a specific distributed object system. particularly in managing the distributed image processing objects on MICS(Medical-Image Conference System). In this paper, We propose and implemented Object Manager with the load distributing policy for CORBA-based MICS to minimize the response time for a particular image processing requests. Object Manager collects and manages the informations such as the processing speed on a particular system, number of IPOs currently executing on a particular system, availability of IPO, and the size of image being requested to be processed, and returns most appropriate IPO with the minimum job response time expected on a given image. We showed with experiments that the improved MICS with the proposed Object Manager has much more shorter job response time about 9 ∼ 22 % than the system using CORBA basic services.

집적화된 실리콘 압력센서의 출력전압 보상파라미터 추출 및 그 특성

An integrated silicon pressure sensor has been designed, fabricated and tested. The signal conditioning circuits were designed to include calibration and temperature compensation of output voltage through trimming of diffusion and ion-implanted resistors. Before trimming of resistors, the compensation parameters such as pressure sensitivity, temperature coefficient of pressure sensitivity, temperature coefficient of piezoresistors and pressure sensitivity of piezoresistors were measured. Then offset voltage, span, and temperature coefficients of offset voltage and span were calibrated by trimming of resistors. The measured output voltage met our design specification and simulation value above room temperature. But, the measured output voltage at -30°C deviated from our design specification and simulation value because the offset voltages were found to vary randomly as a function of temperature.

High-Performance Hybrid Buffer Layer Using 1,4,5,8,9,11-Hexaazatriphenylenehexacarbonitrile/Molybdenum Oxide in Inverted Top-Emitting Organic Light-Emitting Diodes

Park, Cheol Hwee,Lee, Hyun Jun,Hwang, Ju Hyun,Kim, Kyu Nyun,Shim, Yong Sub,Jung, Sun-Gyu,Park, Chan Hyuk,Park, Young Wook,Ju, Byeong-Kwon American Chemical Society 2015 ACS APPLIED MATERIALS & INTERFACES Vol.7 No.11

<P>A high-performance 1,4,5,8,9,11-hexaazatriphenylenehexacarbonitrile (HATCN)/molybdenum oxide (MoO3) hybrid buffer layer with high hole-injection efficiency and superior plasma resistance under the sputtering process was developed. The HATCN enhances the hole-injection efficiency, and the MoO3 effectively protects the underlying organic layers from plasma damage during deposition by sputtering. This improves the characteristics of inverted top-emitting organic light-emitting diodes using a top transparent conductive oxide electrode. The device using the hybrid buffer layer showed the highest electroluminescence characteristics among devices with other buffer layers. The high hole-injection efficiency of HATCN was shown by the J-F curve of hole-only devices, and the plasma protection performance of MoO3 was shown by atomic force microscope surface morphology images of the buffer layer film after O-2 plasma treatment.</P>

Ju Hyuk Park,Young Her,Bo Mi Chun,Chul Woo Kim,Sang Seok Kim 대한피부과학회 2009 Annals of Dermatology Vol.21 No.3

Eruptive vellus hair cysts are asymptomatic, flesh-colored-to-bluish, 1-to-4 mm-sized papules that are usually located on the chest and extremities of children and young adults. Histologically, small cysts are observed in the mid-dermis and these cysts contain multiple hair shafts and keratinous materials. We report here on a case of eruptive vellus hair cysts that developed on a rare site, the labium major. (Ann Dermatol 21(3) 294~296, 2009)
