  • The purpose of the study was to find out which posts were answered in a text-based computer-mediated social support group. Specifically, the present study examined the effects of two variables on support-seeking behaviors: support-seeking strategies and gender. A revised typology of support-seeking strategies originally proposed in the Sensitive Interaction Systems Theory (SIST) model was employed for the study. Data were collected from the PTT psychosis discussion group, the largest BBS in the Chinese-speaking community, for a period of 30 months from February 2004 to July 2006. In general, the results indicated that posts with more asking, less crying and less hinting were answered more than posts with more hinting, more crying and less asking. However, although different support-seeking strategies did affect support-seeking behaviors, gender did not have an impact on which posts were answered.

  • Auditory hallucinations are cardinal feature of psychosis. But the mechanism of hallucinated speech is unknown. The hypothesis that these hallucinations arise from pathologically altered brain monitoring system underlying speech perception is influential. With the help of rapidly developing neuroimaging study technologies, many researchers have been finding new organic deficits in the hallucinated schizophrenic patient's brain. In this article, we reviewed the general appearance of hallucination, a computer simulation model of hallucination and several neuroimaging study findings on hallucinating schizophrenic patients. In conclusion, we presented the presumptive mechanism of hallucination based on the anatomical dysfunction of schizophrenia.

  • Recent studies on long-term outcome of schizophrenia revealed that schizophrenic symptoms recover in more than 50%, while it remains severe in less than 20% after 20 years or more from the onset. Psychopharmacological studies indicate that 75% of remitted schizophrenics may recur within 2 years after discontinuation of maintenance pharmacotherapy. In addition, family studies revealed that schizophrenic decompensation may occur significantly more frequent in discharged patients with high expressed emotion family than in low expressed emotion family. These findings strongly support a clinical validity of stress-vulnerability concept of schizophrenia which open a new viewpoint to two central problems in schizophrenia treatment, i.e. psychotic relapses and chronification of the fist episode schizophrenia. Moreover, recent psychopathological studies argue that schizophrenic symptoms are manifestations of psychological reaction secondary to a primary cognitive impairment(neurobiological vulnerability), which is originated in neurobiological changes in the brain. Recent approaches to the vulnerability to schizophrenic symptoms or schizophrenic decompensation are reviewed.

  • Parkinson's disease (PD) is the second most common neurodegenerative disorder. Although its major manifestation is motor symptoms, resulting from the loss of dopaminergic neurons in the substantia nigra, psychiatric symptoms, such as depression, anxiety, hallucination, delusion, apathy and anhedonia, impulsive and compulsive behaviors, and cognitive dysfunction, may also manifest in most patients with PD. Given that the quality of life - and the need for institutionalization - is so highly dependent on the psychiatric well-being of patients with PD, psychiatric symptoms are of high clinical significance. We reviewed the prevalence, risk factors, pathophysiology, and treatment of psychiatric symptoms to get a better understanding of PD for improved management.

  • Schizophrenia is one of serious mental illnesses and is often described as a heterogeneous disorder. Approximately one-third of schizophrenia cases are treatment-resistant schizophrenia (TRS). The aim of this study was to review the definitions and clinical features of TRS. Though it was found that the criteria for TRS were considerably diverse, the Treatment Response and Resistance in Psychosis (TRRIP) consensus criteria were recently introduced. According to the TRRIP criteria, TRS should be suspected if symptoms persist alongside psychotic symptoms despite sufficient treatment for ≥12 weeks, or two or more symptoms persist significantly for ≥6 weeks. The clinical characteristics of TRS includes an earlier age of onset, more severe and familial form, possibly more rural residence, unlikely association with male sex, and an increase in cognitive deficits.

  • This study was a survey done for the purpose of constructing a nursing theory according to Korean culture and to identify the traditional Korean view of humans and the expectations of the sick role, and to confirm changes from the traditional view of humans and expectations of the sick role according to general characteristics of the population. The subjects were all adults over 18 years old. 517 who lived in six large cities and 191 who lived in five rural communities. Data collection was done from November 19th, 1994 to January 19th, 1995 using a tool to measure the traditional view of humans and expectations of the sick role which was developed by the investigator through a literature review. Collected data were analyzed using frequency, percent, Cronbach alpha, 1-test, F-test and Scheffe post hoc contrasts, with the SAS program. The results of this study are summerized as follows : 1. The Traditional view of human score for all subject was 49.92, which shows that Korean traditional view of human is moderate. High scored items were "human need to live by making harmony with nature, not by overcoming the nature" (3.44), "Filial duty to parents and elders is important" (3.31), "Think of family more than a individual" (2.96). 2. The differences in the traditional view of humans between residential districts showed that the residents of Chungbuk(56.00), Kyungbuk(55.26), Chonbuk(51.32), Taegu(50.59) had a more traditional view of humans than those in Pusan(45.42) and Seoul (47.27). 3. The differences in the traditional view of humans according to general characteristics showed that rural community residents, males, older people, people with lower levels of education, married and house-resident groups had a significantly higher traditional view of humans than urban residents, females, younger people, people with a higher levels of education, single and apartment-resident groups. There were differences according to religion and job. Buddhism had a higher traditional view of humans than those of atheism, Christianity and Catholicism and physical workers, a significantly highers score, than technicians and professional workers. 4. Daily expected task performance during illnesses was lowest for patients with stroke (2.16) and psychosis(2.40), in which case almost no daily general tasks were expected, followed by arthritis 4.06, peptic ulcer 4.79, headache 4.99 and cough 5.58. The amount of expected role exemption during illnesses was also highest for stroke(2.25), followed by psychosis(2.08), arthritis(1.64), peptic ulcer(1.29), headache(1.16) and cough(1.09). The amount of daily task performance in the acute stage(3.05) was significantly lower than that of convalescent stage(4.95). 5. Total expectation of role exemption according to general characteristics showed that there was no significant differences in urban /rural community, marriage, level of education and religion. By sex, women showed higher expectation of role exemption during illnesses than men. By age, the 31-40 year old group showed lower expectation of role exemption than the 41-50 year old group or over the 61 year old group.or over the 61 year old group.

  • Sympathomimetic amines, especially ephedrine, are a major ingredient in proprietary medications for symptomatic treatment of upper respiratory infections. Their frequent uses can lead to occasional instances of abuse and habituation. The clinical symptoms of ephedrine abuse are similar to that of amphetamine psychosis and resemble closely that of schizophrenia. Because both amphetamine psychosis and schizophrenia are thought to be mediated primarily through the action on catecholamines, ephedrine-induced changes of the biogenic amines can be suspected. However, there were few studies about the central effects of ephedrine because of the milder central action than peripheral. Therefore, the present investigation was undertaken to elucidate the relations between the effects of single or repeated administration of ephedrine on the regional levels of biogenic amines in rat brain and ephedrine-induced CNS stimulation. The male Sprague-Dawley rats weighing $100{\sim}200\;g$ were used. After single or repeated administrations of ephedrine, blocks of tissue were obtained from frontal cortex, corpus striatum, hippocampus, thalamus, hypothalamus, substantia nigra and cerebellum. The concentration of biogenic amines(norepinephrine, epinephrine, dopamine, 5-hydroxytryptamine(5-HT)) and their metabolites (3,4-dihydroxyphenylacetic acid (DOPAC), homovanillic acid(HVA), 5-hydroxyindoleacetic acid(5-HIAA)) were measured by means of high performance liquid chromatography-electrochemical detector(HPLC-ECD). The results obtained were as follows: 1) In the normal rat, the concentration of norepinephrine was the highest in hypothalamus. Dopamine, DOPAC and HVA were highest in corpus striatum, and 5-HT and 5-HIAA were highest in substantia nigra. Epinephrine was not detectable in any part of the brain tissue. 2) In a single administration of ephedrine, the concentration of DOPAC was decreased in corpus striatum. However, the other biogenic amines and their metabolites were not changed. 3) In repeated administration of ephedrine, the concentration of norepinephrine was decreased in all brain region checked. Dopamine was decreased in corpus striatum and substantia nigra and, increased in hypothalamus, and HVA was decreased in corpus striatum. 5-HT was decreased in all brain region except cerebellum and, 5-HIAA was decreased only in frontal cortex. The ratio of 5-HIAA/5-HT was increased in corpus striatum, thalamus, hypothalamus and substantia nigra. These data indicated that, although a single administration of ephedrine did not change the central neurotransmitters, repeated administration of ephedrine caused the decreases of norepinephrine and 5-HT in the most regions of brain, which may be responsible for the emergence of abnormal behavioral effect after ephedrine abuse.

  • 영화 <살인마 잭의 집 The House that Jack Built>은 주인공 잭이 12년간의 연쇄살인과정에서 점차 정신병 증상을 지닌 '광기의 예술가'로 재탄생되는 모습을 다룬다. 강박증 증상을 지니고 있는 엔지니어 잭은 한차 레의 우연한 살인으로 향락을 느끼면서 사람을 죽이는 것을 하나의 예술 형태로 간주하고 이 과정에서 강박증을 극복하게 된다. 본고에서 주목하는 문제는 과연 반복 살인이라는 행위로 강박증 증상이 극복될 수 있는가? 하는 질문이다. 따라서 본고는 잭의 강박증은 살인과정에서 극복 된 것이 아니라 신경증에서 안정화 된 정신병 상태로 이행하면서 그 증상이 사라졌다는 관점을 밝히는 것이다. 프랑스의 유명한 정신분석학자 라캉(Lacan)의 이론에 따르면 인간 주체가 현실적인 안정성을 잃을 때 경험하는 환각이나 망상은 상징계의 틈새로 비집고 들어오는 실재(The Real)와 직면할 때 나타나는 현상이다. 영화 속 잭의 망상으로 구축된 가짜현실과 같은 현상은 잭에게 부성은유의 부재로 인해 '아버지의 이름'(The Name-of-the- Father)이 제대로 자리 잡지 못한 원인으로 나타나는 병리적 증상이다. 따라서 본고는 라스 폰 트리에( Lars von Trier) 감독의 영화 <살인마 잭의 집>의 주인공 잭이 지닌 정신병 구조를 라캉의 정신분석을 통해 해독한다.
