韓相燁 大韓神經精神醫學會 1972 신경정신의학 Vol.11 No.4

Auther eagerly want to know theoretic background of juvenile delinguency and criminology for its problem-solution. So auther attempted to describe historical review and social pychiatric point of view on the subject. Previously auther reported classic literatures on the criminal sociology and psychiatric knowledge. Now auther described various literatural backgrounds on the theory of differential association, the theory of differential identification and the theory of self-concept in this article. These controversial trends were much developed and refined. auther have convictionit take out to prevent the prevalence of juvenile delinquency and criminal outcome. Also it will suspect to be dedicate further modern concepts of various culturaland social theories of the juvenile delinquency.

非行理論에 관한 精神醫學的 考察-(I) : 社會精神醫學的 側面에서

韓相燁 大韓神經精神醫學會 1972 신경정신의학 Vol.11 No.3

Juvenile delinquency in Korea can also not be an eoceptional subject nowadays in conformity with the world social controversial trends. Author concerned about the hot matter. Previously author reported two original articles which was titled as 'social psychiatric studies on the juvenile delinguency among Korean: Psychiatric observations on the incidence and the patterns of delinquent behavior, studies on socioen vironmental factor' at 1970. In these studies results, somewhat characteristics of juvenile delinquent behaviors among Korean. There are major emphases upon the incidence patterns and socioenvironmental factors which were thought to be contributing to the occurance of juvenile delinquency in this society. Author eagerly want to know theoretic background of juvenile delinquency and criminology for the problem-solution. So author planed to describe historical review and social psychiatric point of view on the subject. Also it will suspect to be dedicate further modern concepts of various theories of the juvenile delinquency.

정신증상을 수반한 급성 간헐성 폴피리아의 1예 보고

한상엽,오민웅,김헌석,최수호 大韓神經精神醫學會 1972 신경정신의학 Vol.11 No.2

This is a brief report on a case Acute Intermittent Porphyria observed in the St. Mary's Hospital, Catholic Medical College, Seoul, Korea. The case was originally admitted to the internal medicine department where initial diagnostic workup was made. The case, however, showed various psychoneurotic signs which impressed both internists as well a psychiatrists who saw the case upon consultation that the patient might as well be suffered from hysteria. Consequently the Patient was transfered to the psychiatric free-ward where further observation, family study as well as various laboratory tests thought to necessary, were done. While family study revealed(see pedigree) that one of the patient's aunt and her mother had suffered from the illness which seemed similar with the patient's present illness, and two of her siblings were also found to have suffered from the almost identical illness in the past. Examination of urine also revealed excess in amount of porphobilinogen and uroporphyrin in the urine. Authors stressed the importance 1) interdepartmental consultation, and also of 2) the needs of careful review and evaluation of the results of the basic and further laboratory tests for which paychiatrists tend to pay less attention to those cases with neurotic manifestations.

In general, the viscosity of fluid increases as temperature decreases, and decreases as temperature increases. This phenomenon can be explained by decreasing mobility of molecules as temperature decreases. But, we found the opposite phenomenon that viscosity decreases as temperature decreases in particular mixed surfactant system. To analyze this phenomenon, various experiments have been proceeded such as composition (anionic, nonionic, zwitterionic surfactant), variation of zwitterion surfactants, structure of hydrophobic chains, structure of Hydrotrope, variation of pH. Conclusively, controlling the complex of zwitterion and anionic surfactant, we could control the viscosity of mixed surfactant system on variation of temperature. We analyzed this phenomenon theoretically, and then can complete "The technology of viscosity control by temperatre in micellar phase".

This study was primarily designed to examine the probable difference, if any, of c causing factor to suicide among those who had previously attempted to commit suicide and initially attempted to commit suicide. The subjects were those who attempted to commit suicide and brought to the Suicide Prevention Center, Catholic Medical Center during the period from November 1, 1969 to December 31, 1971. Number of the subjects studied was 55 cases of re-attempted suicide and 159 case of once-attempted suicide in the period. The subjects represent the number which were thought to have met sufficiently the designed criteria for this particular study in terms fo cooperation, length of stay in the hospital and degree of reliability. The subjects were interviewed by the authors by the means of general psychiatric interview technique along with questionnaire card that had already been prepared for the purpose. Followings were the main results of the study: (1) Age distribution relatively that it was heavily concentrated to the ages of adolescent & old age group. (2) Sex distribution revealed no significant difference on the re-attempted suicide and once-attempted suicide. (3) The majority of the re-attempted suicides were tentatively diagnosed as schiazophrenia (23.63%) & personality disorder (20.0%). (4) The direct motives for the re-attempted cases were that of psychological problems such as mentai diseases, frustrated love relationship, inferiority, family discord & financial crisis et al. (5) Of the total number of 55 cases of re-attempted suicides, 10.9% of the interviewees accepted the need for further psychiatric treatment despite the fact that the physicians explained them the need of further care by every possible means. 76.36% had frankly denied the needs.

비행청소년의 생태학적 고찰

한상엽 최신의학사 1977 最新醫學 Vol.20 No.6

The present study is planned to summarize the more advanced ideas through enlargement & revision of the conclusions obtained previously from the original article, "Socio psychiatric studies on the Junvenile delinquency among Korean", which was reported at 1970. Objects of 68 male juveniles were studied, who were under confinement in "Seoul Provincial Correctional Institute for Juvenile Delinquents" at the end of Sept. in 1976. The data recognized to be eligible for the study were collected by follow-up study c special emphasis upon the main theme: The specially framed socio-environmental structure, attitude and correlativity of their related factors. Psychiatric considerations were given upon the sex, age, schooling, status of health, character patterns, incidence patterns, time of onset, duration of treatment, present status, past career, parent-child relationship and their attitudes. Though 6 yrs' follow-up study, it might be concluded that intrafamilial conflicts and their destructive relationship, parental attitudes in bringing up their children play an remarkably important role in precipitating delinquency in this society. And in regard further study might be indispensable.

學校恐怖症例의 精神治療 體驗

韓相燁 大韓神經精神醫學會 1976 신경정신의학 Vol.15 No.3

Having treated 9 cases of school phobia with psychotherapeutic approach for last 3 years, author reported about significant 3 cases of 9, in which author insisted that modifying trends of clinical feature are noted and tends to occur in older age group in Korea. Changing patterns were impressed that school phobia is developed in succeeding 3 stages; hypochondriacal stage, aggressive stage and autistic stage. Some cases improved before reaching the third stage but despite of intensive psychiatric care some grew worse in progress, falling into psychotic level andso psychotherapy was confronted with much difficulty. Through review articles of school phobia and with his own clinical expirences, author suggest that school phobia is a typical anxiety neurosis in schoolage in a viewpoint that psychodynamism of it depends on as current propose not only whether selfidentity is well administere or not but also a seperation anxiety.

청소년의 신경증적경향

한상엽 최신의학사 1975 最新醫學 Vol.18 No.4

This study was designed to check the obsessive-compulsive trends by structured questionnaire among the subject of 4,460 persons, including junior high school students, high school students and college students, The results obtained are as follows: 1) Not a few healthy students showed suicidal rumination, obsessive-compulsive nature, guilt feeling and, problem of eye-contact. 2) Obsessive-compulsive nature and suicidal rumination was more froquently -found in female subjects than in male. Guilt feeling was more frequently found in female subjects than in male except `thinking about filthy things which cannot be talked about" 3) In. male subjects, neurotic trends were most frequently found among second grade of high school students. But in female subjects, it was most frequently found among junior-high school students, Suicidal rumination was found in younger age group in female subjects compared with that of male. In both sexes ideas of reference was most frequently found in junior-high school students, and which diminished with aging. From this result, we could draw the possibility of tendency toward social conformity was matter of interest in developmental process. 4) Ideas of reference and suicidal rumination was frequently associated with guilt feeling. Hypochondriacal trends and obsessive-compulsive nature was less frequently associated with quilt feeling. 5) No significant relationship between neurotic trends and birth-order could be found in normal subjects. Traumatic infantile experiences were found less influential than present environmental factors in developing neurotic trends in normal subjects.

중합효소연쇄반응(Polymerase Chain Reaction)을 이용한 Porphyromonas endodontalis의 동정에 대한 연구

이상엽,윤수한 大韓齒科保存學會 1998 Restorative Dentistry & Endodontics Vol.23 No.1

Porphyromonas endodontalis, and anaerobic Gram negative cocobacillus which was known to be associated with the infected root canals and periapical lesions, is very difficult to culture and to detect by the traditional method in that it requires much time to induce the specific black pigmentation, and it is very sensitive to oxygen and the antibiotics added in the culture medium. In this study, the nucleotide sequences of the 'probe h' (0.73kb), one of the specific DNA probes to P.endodontalis (ATCC 35406) which had been developed by our department, was determined and then a pair of primers for PCR amplification was fabricated to identify P. endodontalis. The plasmids containing 'probe h' were purified by Wizard^TM Midipreps DNA Purification System (Promega Corp.), and the nucleotide sequences of the 'probe h' were determined by the dideoxy chain termination method using TaqTrack Sequencing System (Promega Corp.) and detected by fluorescent labelling method. The sense/antisense PCR primers were designed with computer software (Lasergene, DNASTAR Inc.). PCR was done with a programmable GeneAmp PCR System 2400 (Perkin Elmer-Cetus Co.). Each sample containing the whole genomic DNA of P. endodontalis and other black-pigmented Bacteroides was itailly denatured at 94℃ for 5 min and then subjected to 30 cycles, each of them consisting of 60s at 94℃, 60s at 60℃, and 90s at 72℃. The amplified DNA was resolved electrophoretically in a 1.0% agarose gel in 1X TAE buffer, stained with EtBr, and photographed on a UV transilluminator. The results were as follows : 1. The nucleotide sequences of 'probe h' (743 base pairs) were obtained by dideoxy chain termination method, and from that results the specific primers to P. endodontalis (ATCC 35406), 'Primer H1/ Primer H2', were designed. 2. It has been found that 'Primer H1/H2' could detect P. endodontalis (ATCC 35406) using PCR. 3. The PCR system with this primers may be a powerful technique to amplify the specific sequences of 'probe h' of P. endodontalis (ATCC 35406) that produce distinct identification of it from other black-pigmented Bacteroides, and this could help us to determine the nature of periapical disease.
