A 21 years old K. M. C. enlisted man came to the Seoul naval hospital on Jun 5th 1967, complain of asymmetrical facial swelling with facial weakness and painful swelling due to pericoronits on lower left 3rd molar region. Extending from behind the ear through the cervical region. Three days later this patient reveals that facial paralysis was developed._on the affected side. The patient was given penicillin 1, 500, 000 units and streptomycin 1.0 gram perday for one week. One week later surgical tooth extraction was performed. Following the tooth extraction, physical therapy was done combined with steroid therapy. Two months after therapy, there was complete recovery of the facial nerve and all facial movements were within normal limits.

To provide data on the clinical issues related to the birth order and other characteristic background in epilepsy, 331 idiopathic epileptic patients were evaluated and analyzed phenomenologically. The patients had been treated at the neuropsychiatric department of the Korea University Hospital during 1974 to 1980. The age at onset ranged from 1 to 45 years, with the mean age of 16.65 years. Males were 1.36 times more than females. Seventeen (5.13%) of the subjects had the family history of epilepsy. Attacks in the daytime only occurred in 67.67% (N=224) of the subjects, while 23.56% (N=78) had their seizures only at night, and 8.77% (N=20) had their seizures both at daytime and night. Grand mal was the most frequent type of seizure, followed by psychometer and petit mal. There was a higher incidence among the first born than the subsequent siblings and the children born second had a somewhat higher frequency of epilepsy than the subsequent children.

주정정신병

The relation between alcohol and the so-called alcoholic psychoses is not as simple as was formerly assumed. In many instances alcohol serves merely to release a reaction that is primarily psychogenic with factors intrinsic in the personality. In other cases there is such an interplay of psychogenic and metabolic factors that the picture becomes complex. In Korsakoff's syndrome and in chronic alcoholic deterioration, the psychosis is not, as was formerly believed, caused by the toxic effects of the alcohol itself but by thiamine deficiency. Even in this, the structure of the personality influences the picture. It is important to remember, too, that alcoholism may be a symptom-sometimes the most obvious symptom-of another personality, disorder, such as depressive psychosis, schizophrenia, or paresis.

타원곡선 암호시스템에 관한 연구

이병윤,박종서 한국항공대학교 2000 論文集 Vol.38 No.-

공개키 암호 시스템으로 가장 널리 사용되고 있는 알고리즘은 512비트 RSA 시스템인데 최근에 공격을 당해 이 시스템에 대한 안전성에 대한 관심이 집중되고 있다. 현재에는 1024비트 RSA시스템을 기본 사양으로 하고 있으며 보안이 중요시되는 영역에는 2048 비트 시스템을 권장하고 있다. 하지만 시스템의 성능 측면이나 키 관리 측면에서는 큰 사이즈의 키는 부담이 되고 있다. 그래서 비트 당 안전도가 가장 높은 타원곡선 암호시스템이 차세대 공개키 암호시스템으로 주목을 받고 있다. 본 논문에서는 타원곡선 암호시스템에 대한 이해를 높이기 위해 타원곡선 암호시스템의 전반적인 사항들에 관해서 설명하고 기존에 있는 타 공개키 암호알고리즘과의 성능을 비교하였다. One of widely used public key cryptosystem was 512bit RSA system. But recently, Some of 512bit RSA code was cracked. Therefore many people are concentrating on the security level of this system. Now, 1024bit RSA system is minimally required, and people recommend 2048bit system for high security system. However, big size key is not suitable for efficiency or key management of the system. In this reason, elliptic curve cryptosystem gets much attention from many researchers as a candidate for next generation public key system due to highest strength per bit. This paper provides an overview of elliptic curve cryptographic systems and compares the performance of ECC with other systems.

The author studied on the callosal function of 20 chronic schizophrenic patients who met DSM-Ⅲ criteria and compared the results with those of age, sex matched 20 controls. In this study Cross Retrieval of Small Test Objects, Cross Replication of Hand Postures and Cross Localization of Fingertips, which are known as test that can evaluate interhemispheric transfer of information, were used. The results were as follows: 1) Correct answers in normal control group were 633 out of 640 total questions with 98.9% of correctness, which approximates almost 100%. 2) Number of mean errors in patient group(2.8000±2.262) was higher than that of control group (0.400±0.503) and the difference between the 2 groups was significant (p<0.001). 3) Number of delayed responses in the patient group(3.100±2.789) was also higher than of control group (0.5500±0.887)and the difference between the 2 groups was significant too (p<0.001). 4)Subtype (paranoid vs undifferentiated), family history of mental and/or neurological disease and sex in the patient group made no difference. With the above results the author suggest that chronic schizophrenics suffer from callosal dysfunction and schizophrenic patients (in the case of paranoid and undifferentiated type)are homogeneous in terms of callosal function as far as family history and sex are concerned.

思春期週期性精神病에 關한 臨床的考察

宋南玉,閔秉根,李丙允. 大韓神經精神醫學會 1962 신경정신의학 Vol.1 No.1

Writers observed psychotic syndromes in adolescents whose symptoms are relatively brief and cyclic or periodical in nature. The term periodic psychosis in preadolescence or adolescence is used in the report by Kleist and Sukhareva. Although the term itself has no objection, many listed different views, on its etiological or pathognomonic areas. This report presents 3 adolescents whose symptoms are brief and unique on the one hand, they are also periodical on the other. 2 girls reported here showed acute psychotic pictures which were similarly brief and the periodicity was overlapped to their menstrual cycles. Another case is a boy of 17 whose symptoms were quite similar to the above. Clinical pictures shown by the three are those of catatonic schizophrenia in our impression.

Johnaon과 Szurek 등이 발표한 반사회행동의 원인적 요소로서 중요한 요인이 되는 경우를 다음과 같이 증명했다. 즉 부모를 스스로가 금지된 욕구의 조정이 불가능한 경우 의식적은 아니지만 부지불식간에 자식들의 반사회적을 조장하고 허용함으로서 그러한 자식들의 행동을 통하여 대리적인 만족을 추구하는 경우가 있다는 사실입니다. 이런 경우에는 부모들이 자식들을 증오하는 무의식적이며 신경증적인 파괴욕구로 자식들의 처벌을 해결되고 있는 것이라고도 했다. 이러한 요소가 특히 앞서 말한 사회적 지위나 경제적 조건이 훌륭한 가정에서 발생하는 범죄소년들과 부모와의 관계에서 가장 흔히 발견되는 요소인 것이다. 그러나 이런 아이들의 상위자아 혹은 양심은 광범위한 결함이 있는 것은 아니며 절도 폭행, 성범죄, 방화, 무단결석 혹은 가출등 어느 한 부분에만 억제력의 결함이 있고 딴 부분의 자제력은비교적 정상적으로 유지되고 이음이 특지인 것이다. 특히 이를 개별적인 범죄소년들은 그 어머니와의 관계에 있어서 중요한 문제가 있는 것이며 자식들에 대한 기대, 이상 개념이 확실하고 확고치 못한 어머니를 가졌을 때 발생하기 쉬운것이다. 자식들이란 부모를 동일시함에 있어 부모들이 표면적으로 또 의식적으로 강조하고 행동하는 면을 동일시하는 것이 아니라 부모가 자기에게 갖고 있는 무의식적인 감정이나 개념까지도 모두 동일시하게 되는 것이다. 정신적으로 건강한 부모들 심중에는 자기자식들 역시 부모나 마찬가지로 사회가 설치했고 부모가 요구하는 회사와 법의 질서를 으레히 잘 지켜줄 것이라는 무의식적인 확고한 태도를 갖고 있는 것이며 따라서 잘 통정되며 있고 원숙한 인격을 갖고 있는 어머니라면 자식들에게 일단 명령한바나 요구한바는 어김없이 자식들이 실행할 것이라는 의식 무의식적 확고한 태도를 갖고 있게 되지만 신경증적이며 특히 증오감과 죄악감을 해결하고 있지 못하는 어머니는 어떤 연령이나 요구를 자식들에게 해 놓고 나서도 불안해 하고 초조해 하게 되며 자식이 어머니의 연령이나 요구를 어기고 실시하지 않을 것까지 염려하여 성화 같은 잔소리와 더불어 자식들이 어머니의 말을 듣지 않는 것은 불효이고 나쁜 사람이라는 도덕적인 설교와 협박까지 하는 경우에는 자식들은 어머니가 갖고 있는 자기에 대한 음성적인 면의 개념 즉 불량하게 되는 것을 은근히 바라고 있는 것 같은 이러한 어머니의 태도를 알아차리게 되고 또 그것까지도 동일시하게 됨으로서 뜻하지 않은 경우에 반사회적인 행동을 저지르게도 되는 것이다.

Family of a case muscular dystrophy with schizophrenia and mental retardation are presented. The family are consisted of three brothers and a sister with their living parent. Two brothers of them show progressive muscular dystrophy with schizophrenia and mental retardation, and the youngest brother shows only the muscular dystrophy. The results of this study were as follows; 1. Progressive muscular dystrophy is considered as one of familial trait. 2. Progressive muscular dystrophy occurs in males. 3. Mental retardation seems to be undully common in the Duchenne type of progressive muscular dystrophy. 4. In the progressive muscular dystrophy, there are no neurological symptoms nor signs of central nervous system and the significant pathological findings are confined to the muscle.

Lithium 유지요법

이상연,곽동일,이병윤 大韓神經精神醫學會 1975 신경정신의학 Vol.14 No.3

Many studies of lithium maintenance treatment for the manic-depressive patients were reported. In order to estimate the effectiveness of lithium maintenance treatment as a preventinn of recurrence of maic-depressive attacks. the authors selected 12 cases of maic-depressive psychoses who had more than one attack in the past several years and under treatment of lithium maintenance treatment in the Department of Neuropsychiatry, Woo sok Hospital, Korea University. The result were as follows: 1. Only 4 patients among 11 cases who has no recurrence so far up to the date of this reported showed 0.6 -1.2mEq/L in serum Lithium level. 2. One patient who was under control for about 12 months with 600mg of lithium carbonate had another attack again 10 months after dropping out of the maintenance treatment 3. There is no evidence of interrelations between body weight of the patients, serum lithium level and maintenance dosage.

임부와 정신적 손상

Clear scientific evidence that psychological trauma in pregnancy can have lasting effects on the fetus has been hard to establish. Nevertheless there is a long history of folk belief in such effects. In our culture it has been said that sudden terrifying experience of pregnant woman easily provoke miscarriage. Scientific observers may have been especially skeptical of such beliefs, but in the case of pregnancy, one might particularly look for ways in which the thalamic-pituitary-adreno-cortical sympathetic nervous system responses to stress might adversely affect either the maternal physiology of pregnancy or the developing fetus. For example, a number of studies have shown that catecholamines can produce varied effects, including uterine hyperactivity and vasoconstriction, changes in fetal neuroendocrine growth and development and variations in the timing and quality of labor.
