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.

Ciinical characteristics of schizophrenic patients with sexual thought were compared to those without sexual thought in 72 schizophrenic patients diagnosed by DSM-III-R who admitted at the psychiatric inpatient unit of Chonnam University Hospital from September, 1986 to August, 1988. The results were as follows ; A. The themes and frequency of sexual thought. l) The highly frequent themes were hetero-sexual matter(l6.9%), incestuous wishes and impulses(15.1%), idea of referenced 15.1%). The less frequent themes were erotomanic delusions and ideas, delusions concerning being sexually persecuted and honisexual fears and wishes. B. Significant diiierences(p<0.51) between two groups were as follows : 1) In father's rearing altitude, overprotection occured more frequently and rigid attitude occured less frequenttly in group with sexual thought than control group. 2) In group with sexual thought, parental marital dissatisfaction, parental marital disharmony and extramarital affairs and polygamy were more frequently noted than in control group. 3) Early sexual experiences were high present in group with sexual thought. 4) The personal sexual precipitating factors were more frequent in patient group with sexual thought. C. Some of the statiatically nonsignificant differences between two groups were as follows; 1) In the demographic background, mean age and educational level were lower in group with sexual thought. Patients with sexual thought had more likely unskilled labor, unemployed state in occupation. 2) The personal nonsexual precipitating factors were more frequently in control group. 3) The marital dissatisfaction of patients were more frequently in patients with sexual thought.

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.

The standard neurologic examination was performed to evaluated prevalence of abnormal findings and their clinical significance for schizophrenic patients. DSM-III-R diagnosed, age-and sex-matched groups of 35 schizophrenic patients, 24 patients with bipolar affective disorder with history of psychosis, 26 patients hospitalized for alcohol dependence or other drug abuse, and 33 normal volunteers were the subjects. All three patient groups had significantly more total abnormalities than normal control group, but there were no significant differences when patient groups were compared with each other. When the findings due to medication or others unrelated to the pathogenesis of psychiatric illness were-excluded, the differences between the following groups, i.e., the schzophrenic group vs normal control group, schizophrenic group vs bipolar affective disorder group, and alcohol dependence and other drug abuse group vs normal control group, remained significant. When those neurologic abnormalities indicating localized dysfunction of the corticospinal tracts, basal ganglia, or cerebellum were considered, only two pairs showed significant differences. They were schizophrenic group vs normal control group and alcohol dependence and other drug abuse group vs normal control group.

Anxiety and depression appear frequently in patients who are on hemodialysis. We tried to find whether showing anxiety and depression was related to coping strategy they used in crisis. One hundred and five patients who were on hemodialysis at Chonnam National University Hospital. Chosun University Hospital, Kwangju Chri Hospital or Kwangju Namkwang Hospital from Aug 1st, 1990. to Oct 10th, 1990 were compared with thirty persons. The results were as follow : 1) Hemodialysis patients showed anxietyand depression more frequently than normal persons. 2) More frequently used coping strategies are redefinition, suppression and intellectualization. Depression was strongly correlated with fatalism, acting out, isolation, state anxiety was correlated with shared concern, reduction, isolation and self-pity, but trait anxiety was not correlated with coping in this study.

Chronic antipsychotic treatment can induce tardive dyskinesia and supersensitivity psychosis, and these may be explained by supersensitivity phenomena of the dopamine receptor in the brain. This study was conducted to compare the clinical characteristics between tardive dyskinesia and supersensitivity psychosis in schizophrenia. The subjects of the study were composed of 8 schizophrenics with tardive dyskinesia(TD ), 10 schizophrenics with supersensitivity psychosis(SP), and 5 schizophrenics with both syndromes(TD with SP). They all had been treated with antipsychotics. We compared the difference in general and antipsychoti-related characteristics among the three groups. The results are as follows : 1) In the comparison of general characteristics ; There was a significant difference in the number of hospitalizations among the three groups. The number of hospitalizations was most frequent in SP group, and this was followed by TD with SP group(P<0.05). There was also a significant difference in the length of hospitalization : the longest in SP group and the shortest in TD group. Among the schizophrenic subtypes by Andreason-0lsen's criteria, the number of positive schizophrenics were significantly greater in SP and TD with SP group than in TD group(P<O.05) . 2) In the comparison of antipsychotic-related characteristics : There was a significant difference in the current antipsychotic dose among the three groups. The current antipsychotic dose was highest in SP group and this was followed by TD with SP group(P<0.05). The therapeutic response to antipsychotics was significantly better in SP group than in TD group, and the serum prolactin level was significantly higher in SP group than in TD group, and the serum prolactin level was significantly higher in SP group than in TD group(P<0.05; respectively) 3) Regardless TD, if SP was present, the serum prolactin level was significantly correlated to the current antipsychotic dose(P<0.05). 4) But, there was no significant difference in mean age, age of onset, duration, schizophrenic subtype by DSM-Ⅲ criteria, duration of antipsychotic treatment, prognosis, and antipsychotic potency among the three group.

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.
