李亨榮 中央醫學社 1977 中央醫學 Vol.32 No.5

The results from the comparative study of two previous surveys, One performed from Jan. 1st to Dec. 30th 1972, the other from Jan. 1st to Sept. 30th 1975 are compared and reviewed. The author conclude that treatment methods before psychiatric admission have changed considerably with evolution of culture in times during the short period over two surveys. Particularly, of those, utilization of modern medical treatment and drugs at drug store has been increased, while that of herb medicine, shaman, home remedy has been decreased. The relations between treatment methods and those factors such as age, educational levels, area of residence, and occupation show no significant changes.

Most clinicians agree that the group of disorders called schizophrenia is heterogeneous. Since Kraepelin described dementia praecox, various attempts have been taken to subdivide schizophrenia into several homogeneous subtypes. Recently some investigatiors were interested in the division of schizophrenia by use of positive & negative symptomatology that Hughlings-Jackson had tried. Crow especially hypothesized that there were some differences between the tow prominent symptoms(negative & positive) in respect of premorbid adjustment, response to neuroleptic therapy and underling pathologic process etc. But this hypothesis remains largely untested. Using Andreasen & Olsen's criteria for negative, positive and mixed schizophrenia, we subdivided a consecutive sample of 67 schizophrenic patients into 3 subtypes (negative 21, positive 23, mixed 23). We then evaluated some characteristic aspects among these 3 subtypes. The results are as follow : 1) There was s significant difference in mean age among the three subtypes. In the negative group, the mean age was most high and this was followed by the positive group(p<0.05). 2) There was a significant difference in the duration of education among the three subtypes. In the negative group, the duration of education was least and this was followed by the positive group(p<0.05). 3) There was a significant difference in premorbid adjustment among the three subtypes. The level of premorbid adjustmentwas lowest in the negative group and this was followed by the positive group.(p<0.005). 4) There was a significant difference in the number of previous hospitalizations among the three subtypes. In the negative group, the number of hospitalizations was lowest and this was followed by the positive group.(p<0.005). 5) The experience of previous modern psychiatric treatment was more reare in the negative group and this was followed by the positive group.(p<0.05). 6) The score of mini mental status for evaluation of cognitive function was significantly lower in the negative group and this was followed by the positive group.(p<0.001). 7) The scores of the BPRS for evaluation of psychotic symptoms at the times of admission and 4 weeks later were significantly most high in the positive group and this was followed by the mixied group (p<0.05, respectively). The therapeutic response rated on the BPRS after 4 weeks, was significantly prominent in the positive & mixed groups(p<0.05, respectively), but not in the negative group. 8) Besides these, there were no significant differences in occupation, onset of age, duration of illness and family history among the three subtypes. .

일반화 공간 변조 시스템에서 송신/수신 순서화를 적용한 효율적 구복호 수신기

이형영,박영웅,김종민,문현우,이경천,Lee, Hyeong-yeong,Park, Young-woong,Kim, Jong-min,Moon, Hyun-woo,Lee, Kyungchun 한국정보통신학회 2017 한국정보통신학회논문지 Vol.21 No.3

본 논문은 송신에 이용되는 활성 송신 안테나와 송신 심볼을 이용해 정보를 전송하는 일반화 공간 변조 시스템에서 송신/수신 순서화를 결합하여 기존의 구복호 수신기보다 낮은 계산 복잡도를 갖는 수신 방식을 제안한다. 제안 수신기는 수신 순서화를 통해 수신 신호 연산을 최적의 순서로 수행하여 구 밖의 후보해에 대한 연산을 조기에 종료함으로써 계산량을 줄인다. 또한, 송신 순서화 방식을 적용하여 심볼과 활성 송신 안테나 탐색에서 해일 확률이 높은 후보 해부터 탐색을 수행하여 계산량을 낮추도록 한다. 모의실험을 통해 송신/수신 순서화를 적용한 제안 구복호 수신기가 기존 구복호 기법, 수신 순서화만 적용한 구복호 기법과 비교하여 동일한 비트오류율 성능을 유지하면서 더 낮은 계산 복잡도를 가짐을 확인하였다. In this paper, we propose an efficient sphere decoding scheme that reduces computational complexity by combining receive and transmit ordering techniques in generalized spatial modulation systems, where the indexes of activated transmit antennas as well as the transmit symbols are exploited to transfer information to the receiver. In this scheme, the receive signals are optimally ordered so that the calculation for a candidate solution outside the sphere is terminated early to lower the computational complexity. In addition, the transmit ordering technique is applied to first search for candidate symbols and activated antennas having higher probabilities to further reduce the computational complexity. Simulation results show that the proposed doubly ordered sphere decoding scheme provides the same bit error rate performance with the conventional sphere decoding method and the sphere decoder employing only the receive ordering technique while it requires lower computational complexity.

요양소에 수용중인 정신장애자의 입소전 치료방법에 관한 연구

신병호,윤진상,이충경,이형영 大韓神經精神醫學會 1988 신경정신의학 Vol.27 No.5

In Korea, a large number of the mentally ill are still institutionalized in asylums where they can not receive modern psychiatric treatments. This survey was designed to investigate previous treatment methods of these psychiatric patients and to offer basic data in order to develop modern psychiatric delivery system for patients institutionalized in asylums. The 694 subjects who could give cooperative informations wee selrected form 6 asylums which are located in the Kwang-ju and Chonnam area. The data on this survey was collected by investigator's interview from Mar. 30, 1987 to Apr. 10, 1987. The previous treatment methods were divided into 8 groups(modern psychiatric treatment, asylym, Korean shamanic rite, religious healing, herb medicine, drug store, others and no treatment) and multiple responses were allowed. The methods were studied relating to the following psychiatric and sociodemographic factors : psychiatric diagnosis, age at the time of institutionalization, morbid duration before institutionalization, sex, occupation, residence, religion, economic status, marital status, educational level, and guardian. 49% of the patients had no experienced any previous treatment for their mental illness. 35% of the patients had been given modern psychiatric treatment and 23% had been previously institutionalized in asylums. The other treatment methods were reported in less than 10% of the patients. There were significant relationships between the choice of treatment methods and the psychiatric and sociodemographic factors.

醫科大學生의 睡眠樣相과 性格特性

김욱,윤진상,이형영 大韓神經精神醫學會 1991 신경정신의학 Vol.30 No.6

This study was carried out in order to find out the possible relationships between sleep patterns and psychological characteristics. The subjects were 160 young normal students, 114 men and 46 women, aged 21∼25 years(21.64±1.31). Four aspects of sleep patterns(length, regularity, circardian rhythm and refreshed feeling at the time of awakening) were investigated, based on the sleep questionnaire, a sleep diary of two weeks and a Korean version of the morningness-eveningness questionnaire of Horne and Ostberg(1976). The subjects belonging to the two extreme groups of each aspect of sleep patterns(long vs. short, regular vs. irregular, morning vs. evening, refreshing vs. nonrefreshing) were compaired using the Korean version of MMPI(1989). The results were as follows : 1) With each sleep pattern, the long sleepers were 23(14.38%), short sleepers 16(10.00%) ; regular sleepers 105(65.63%), irreqular sleepers 19(11.88%) ; morning type sleepers 176(10.63%), evening type sleepers 17(10.63%); refreshing sleep 45(28.12%), nonrefreshing sleep group 27(16.87%). 2) There was no significant difference between the long- and short-term sleeping groups. 3) The irreqular sleeping group showed significantly higher scores than the reqular sleeping group in Hs(p<.01), Pd(p<.05), and Scsubscales(p<.05). 4) The evening sleeping groups showed significantly higher scores than the morning sleeping group in F(p<.05) and Hs subscales(p<.01). 5) The nonrefreshing sleep showed significantly higher scores than the refreshing sleep group in Hs(p<.001), D(p<.01), Hy(p<.001), and Pt subscales(p<.001).

This study was performed to investigate psychiatric characteristics of patients who were admitted for general-health evaluation. Subjects were 111 patients who were admitted to Chonnam National University Hospital from May, 1989 to July, 1990. They were diagnosed with DSM-III-R, and evaluated with the Korean version of Symptom-Checklist-90-Revised(SCL-90-R). Author analyzed the demographic characteristics, the result of medical evaluation, and the prevalence of psychiatric disorder. The subscale of SCL-90-R were compared between subjects with psychiatric disorder and those without psychiatric disorder. And discriminant analysis was carried out to examine the discriminating power of SCL-90-R as a screening test for these patients. Results of this study were as follows; 1) The number of male subjects was 66(59.5%) and that of female was 45(40.5%). The mean age of subjects was 44.9±12.7(from 19 to 80 years old). 2) The number of subjects who had past medical or surgical history was 57(51.4%). 3) The number of subjects who had visited psychiatric clinic was 7(6.3%). 4) After medical evaluation, nearly one-third of subjects(31.5%) were found to have no medical illness. Among subjects who had abnormalities by medical evaluation, nearly half of subjects(52%) had no subjective symptom. 5) After psychiatric evaluation, 56.8% of subjects were diagnosed as having obvious psychiatric disorders, such as somatoform disorder(37.9%), depressive disorder(9.0%), anxiety disorder(8.1%) and schizophrenic disorder(1.8%). The female subjects, younger subjects, and subjects who had no medical diagnosis had tendency to have psychiatric disorders. 6) When the subscale scores of SCL-90-R were compared between subjects with psychiatric diagnosis and those without psychiatric diagnosis, all subscale scores except paranoid subscale were statistically higher in subjects with psychiatric diagnosis. 7) After discriminant analysis, the correctively discriminated percentage among subjects with psychiatric diagnosis was 63.5%, and that among subjects without diagnosis was 79.2%. The total correctively discriminated percentage was 70.3%. In summary, these results suggest that relatively large numbers of subjects who were admitted for general health evaluation have psychiatric illnesses and that SCL-90-R can be used as psychiatric screening test for these subjects.
