Objective: This study aimed to investigate changes of the persecutors in patients with schizophrenia and other psychotic disorders with the vicissitude of the times in Korea. Methods: Data were collected from 15 papers (total: 2,944 persons, Male: 1,677, Female: 1,267) about persecutors observed in schizophrenia and other psychotic disorder patients with persecutorU' delusion which were published between 1962 and 2004 in Korea. Persecutors were classified into 7 Classes: CIass 1 (unspecified or all person), Class 2 (family, relatives), Class 3 (neighbors, friends, fellows), Class 4 (the communists, the Red-army, spy), Class 5 (secret agents, Police, political character or army), Class 6 (impersonal), Class 7 (others). 15 published papers were classified into 3 groups (A,B,C) by times: group A (1945-1960, Pros and cons of democracy and communism), group B (1961-1992, Suppression of democracy and anti-communist policy by military), group C (1993-2004, Democracy by civilian). The authors investigated the total frequency (%), tendency of changes, difference of frequency of 7 classes in each group of times (A,B,C). Results: 1) Class 1 was the most common persecutor (25.35%) in all of 3 groups (A,B,C). 2) Class 2 and 6 showed the highest tendency of increase and Class 4 showed the highest tendency of decrease. 3) In comparison of the times (A,B,C), Class 4 in A, Class 5 in B, Class 6 in C showed higher frequency. 4) In comparison between capital region and country, CIass 1 and 5 in capital region and Class 6 in country showed higher frequency. 5) In comparison by sex, Class 3 in male and Class 2 in female showed higher increasing tendency. Class 4 and 5 in male showed more decreasing tendency than female in C times, Conclusion: Persecutors of persecutory delusion in patients with schizophrenia and other psychotic disorders vary by sex and residential region, and have been changing with the vicissitude of the times.

Background and Objectives: Intentional self-mutilation of the genitals in male is exceedingly rare. As the authors experienced 3 cases of male genital self-mutilation while psychotic, we investigated with psychiatric points of view including general and psychiatric characteristics of genital self-mutilation in Korea. Materials and Methods: Total 21 cases of the genital injury were obtained from the index book of Journal of Korean Neuropsychiatric Association and the Electronic Library Search Engine. From these, excluding the 4 accident-caused cases of penile amputation, the authors investigated 17 cases in terms of general epidemiological characteristics, the type of mutilation, diagnostic classification, psychodynamics of their behavior. Results: Epidemiological data showed that the most of the genital self-mutilation cases are twenties (52.9%); most are single (64.7%). In terms of the mutilation types, complete transection of penis type were committed most frequently (72.1%). The formal diagnoses were mainly schizophrenia (82.3%) and schizoid personality disorder(11.8%). Psychodynamically, lots of cases could be explained as to punish failures in the male role (20.6%), related to religiosity (14.7%), and related to physical pain or somatic illness (14.7%). Conclusion: We are unable to say exactly what prompts a man to divest himself of his genitals. On the basis of 17 cases, we are willing to hazard several risk factors. For individuals psychotic at the time of act there seem to be at least three paradigmatic at-risk groups: (1) younger acutely psychotic men with related to cure or punish failures in the male role, (2) the men with personality disorders who act rageful feelings against themselves and/or close objects, and (3) sociocultural factors known to contribute to such an act include some complex religious belief regarding purification or resisting temptation. Psychological factors yet undetermined may be' equally important.

Objective: The authors investigated the frequency of persecutors in persecutory delusions of the psychiatric patients who didn't undergo the arrest or traumatic injury, reside in Gwangju Jeonnam area, and were admitted to the hospital after the 5.18 prodemocracy movement in Gwangju in 1980 upward 10 years. Also this study investigated the frequency of the persecutors before and after the prodemocracy movement and in capital and Gwangju Jeonnam area. Subjects and Methods: Among the 896 patients who were admitted to department of psychiatry, Chosun University Hospital from Jan. 1. 1989 to Dec. 31. 1991, we choosed 144 patients with persecutory delusion who had lived in Gwangju Jeonnam area for 10 years after 5.18 prodemocracy movement as subjects. Persecutors were classified into 7 class: unspecified, family, neighbors, communist or spy, police or army or secret agent, impersonal, others. Results: 1) In our study, the frequency of persecutors was family, unspecified, neighbors, police or army or secret agent, impersonal, others, communist or spy in descending order. As compared to previous studies (1956-2003) including our study about frequency of persecutor at capital area and Gwangju Jeonnam area, and before and after 5.18 prodemocracy movement, 2) At capital area, in the early 1980s, police, family, neighbors, unspecified person was frequent in descending order. In the both of early 1970s, 1990s, neighbors, family, unspecified person, police was frequent in descending order. 3) At Gwangju Jeonnam area, in the early 1970s, family, unspecified person, neighbors, police was frequent in descending order. In the early 1990s, unspecified person and family, neighbors, police was frequent in descending order. 4) The police class was most frequent at capital area in the early 1980s. Conclusions: We suppose that class of persecutor in persecutory delusions of psychiatric patients are changing according to social change, and frequency of police class was decreasing in both of capital and Gwangju, Jeonnam area.

Knowledge Management System is defined as an information system to support the integrated knowledge management process for maximizing value of the knowledge assets in organizations. From that point of view, the system performance - the usage level of the system and user satisfaction - can be an available measure of the knowledge management system success. Many previous research were focused on the application of new technological component for knowledge management processes or the construction of the overall system architecture in spite of the importance of the system performance. The purpose of this study is to identify the factors affecting the knowledge management system performance. To do this, we conducted an exploratory case studies of eight companies. We applied theories of information system success to knowledge management system and investigated some specific strategic components as additional affecting factors. Finally, we proposed research model and six proposition regarding the factors affecting the knowledge management system performance. The implication of the findings and futures research directions were discussed.

Authors analyzed factors influencing the development of peritumoral brain edema in a series of 40 patients with intracranial meningiomas. We used the Edema Index(EI) which was calculated by dividing the size of the meningiomas and peritumoral edema by the size of the meningiomas using the CT scan and MRI. We compared the El with several factors which might influence the amount of peritumoral brain edema. 31 cases among the 40 cases revealed peritumoral edema. The factors which revealed significantly more severe peritumoral edema were meningiomas which were located in falx and frontal convexity, those without radiologic calcifications, meningiomas in solid natures, those which with less homogenous enhancement in the brain CT scan or MRI, and right hemispheric meningiomas.

Objective: This study investigated awareness of mental disease on the part of hospital employees and compared it with that of the general population to identify methods for implementing and maintaining early treatment, Subjects and Methods: The subjects were 177 employees of Chosun University Hospital and 172 hospital visitors. Data were collected using a questionnaire that examined demographics and posed 40 questions on the awareness of mental diseases. Results: 1) Hospital employees were more aware of the prevalence, symptoms, and causes of mental disease than were the general population. 2) Regarding differences in awareness of a mental disease according to occupation within the hospital, hospital administrators had more prejudicial views with respect to supernatural and religious concepts of mental disease, unscientific treatment methods, the condition of a mental disease, and the course of treatment than did doctors or nurses. 3) Regarding differences with respect to direct and indirect experiences of mental disease on the part of hospital employees, the group experiencing no mental disease was less prejudiced, which is contrary to the results for the general population. Conclusions: Hospital employees who have more opportunities to confront mental disease and to receive training had a higher level of awareness of, and more positive attitudes toward, mental disease. Nevertheless, those experiencing a mental disease directly had greater prejudice. Therefore, regarding education about mental diseases, it is necessary that an in-depth education method is designed, one that goes beyond simply delivering knowledge about the various diseases.

The inflammatory myofibroblastic tumor (inflammatory pseudotumor) is a rarely occurring soft tissue lesion of unknown etiology. It can be of any location, but commonly it is found in lungs. It has been considered as a nonneoplastic reactive inflammatory lesion, but nowadays, confusion and dispute about its character is increasing due to its high recurrence rate and metastasis. We present a patient who had been diagnosed with an inflammatory pseudotumor in the right maxilla area, 1 year before visiting our hospital. After that, her pain and swelling did not resolved and she visit our hospital. On radiographic examination, aggressively infiltrative growth of the lesion with destruction of adjacent bony structure was noted. We found unusual aggressiveness of the inflammatory myofibroblastic tumor of the head and neck region. Because the typical behavior of the inflammatory myofibroblastic tumor is not defined yet, we recommend the surgical excision of the lesion and close follow-up.

The purpose of the analysis is the numerical simulation of structures strained to the limit loads. The finite element calculations and experiments with cracked structures have been carried out yielding over limit strains between 10% and 15% by single peak load. Load versus displacement-diagrams and J-diagrams up to the limit load are calculated. By this way the influence of geometric parameters may be assessed in the post yield region. It is proposed to use such calculations to correlate experiments carried out with small specimens to experiments simulating the true dimensions of the design structure.
