To develop optimal shift systems for an improvement of work schedule satisfaction, health and work productivity, the effects of the direction of the rotational work shifting on the circadian rhythm and adaptation of physiological components and work mistakes were investigated in nursing students. Two groups of seven volunteers participated as experimental subjects, apd seven to twenty nursing students participated as a control group. The directions of rotation work shift were as follows CW(clockwise)-shift system rotation in the direction of day shift(3 days), evening shift(3 days), off duty(l day) and night shift(5 days), and CCW (counterclockwise) -shift system rotation in the reverse direction. Urinary Na, K, and Cl levels were measured with ion-selective electrodes. The levels of performance were measured by a questionnaire to determine the number of mistakes in 12 specific items during duty. The disturbance of Na the circadian rhythm was seen on day and night shifts, especially in the CCW-rotation shift system, and the magnitude of the daily variation was greatest in the CCW-rotation system. The daily rhythms of K and Cl shifted to the right on the evening shift, and the rhythms were reversed on the night shift, which suggests that they adapted to the altered shift work. However, the levels of Cl were higher in day and night shift workers, especially in CCW-shift system. In the ease of urine salts, it seems that the students in CW-shift system more easily adapted to the altered shift. The incidence of mistakes during work were more frequent on the CCW shift than in the CW shift. These data indicate that the direction of rotation effects the worker's health and work performance. These results indicate that the CCW rotation of shift work makes it more difficult for the workers to adapt to the shift on a physiological level, and has many more negative effects on the shift workers' health when compared with the CW rotation. Thus, a clockwise rotating shift system seems to be more desirable for the optimal health and performance of nurses.

OBJECTIVE: p16INK4 and p15INK4B genes are known to be tumor suppressor genes which reside in p21 region of chromosome 9 and are related to cell cycle control as an inhibitor of cyclin-dependent-kinase. We designed this study to search for deletion and decreased expression of p16INK4 and p15INK4B genes in advanced ovarian carcinomas. METHODS: Polymerase chain reaction (PCR)-based analysis was performed to search for deletion of p16INK4 and p15INK4B using DNA extracted from frozen tissue in liquid nitrogen of thirty-one advanced ovarian carcinoma patients. The intensities of PCR bands were analyzed using an imaging densitometer to determine gene dosage in tumor samples and the relative gene dosage was calculated by comparing band intesity of p16INK4 or p15INK4B with that of beta-globin gene. Homozygous deletions were assigned to tumors in which the ratio was reduced to less than 25% in any one of exons of p16INK4 and p15INK4B. Immunohistochemical techniques were used to study the expression of p16INK4. p16-negative cells were characterized by the absence of nuclear staining, whereas cytoplasmic staining was variable. Clinico-pathologic features, complete remission rates and survivals were analyzed according to the status of p16INK4 and p15INK4B genes. RESULTS: Homozygous deletion of p16INK4 was detected in 12.9% of advanced ovarian carcinoma patients and that of p15INK4B in 35.5%. Clinico-pathologic features such as FIGO stage, histological grade, serum CA-125 levels were not different from groups with homozygously deleted p16INK4 and p15INK4B to those with normal genes. The survival of patients (13 [6-20] months) with homozygously deleted p16INK4 was significantly shorter than that (30 [8-52] months) of patients with normal p16INK4 (p=0.046; Log-rank test). CONCLUSION: These observations indicate that deletions of p16INK4 and p15INK4B gene might be involved in tumorigenesis of ovarian carcinoma and could be useful as a prognostic factor. A prospective, controlled study with more patients will be mandatory in the future.

BACKGROUND: Dopamine receptors are strong candidates for involvement in schizophrenia and are target of a wide variety of antipsychotics. Dopamine D5 receptor(DRD5) gene polymorphisms may be associated with various treatment response. The purpose of our study was define to what significance can be held as a predictor of treatment response in this polymorphism. METHOD: The total number of 116 Korean chronic schizophrenic patients was assessed after 48 weeks treatment. The Positive and Negative Syndrome Scale(PANSS) was rated for the clinical response to various antipsychotics. With the use of polymerase chain reaction amplification, we assessed this dopamine D5 receptor polymorphism in schizophrenic patients who had been treated with antipsychotics, and related genotype with treatment response, to test the hypothesis that DRD5 polymorphism may lead to varying resonse to antipsychotic. RESULT: DRD5 polymorphism was not associated with treatment response to a variety of antipsychotics in chronic schizophrenic patients. CONCLUSION: Genetic variation of D5 receptors do not predict treatment response to antispychotics.

PURPOSE: This study was aimed to evaluate the effects of a maternal education program based on the temperament theory on the temperamental goodness-of-fit between mother and child. METHOD: The research method was a nonequivalent, control group, non-synchronized design and the experimental period was from May 10, 2004 to July 24, 2004. The subjects were mothers who had children 3-4 years old who registered in eight kindergartens or infant schools in M city. Among the total 94 subjects, 47 were allocated as an experimental group and 47 were a control group. Using the SPSS/WIN 10.0 program, the data was analyzed by a Chi-square test, and t-test. RESULT: 1. After treatment with a maternal education program based on the temperament theory, the experimental group significantly decreased in scores for perceived children's behavior problems in comparison to the control group(t=-4.01, p<.001). 2. After treatment with a maternal education program based on the temperament theory, the experimental group did not significantly decrease in scores for parenting stress in comparison to the control group(t=-.85, p=.40). 3. After treatment with a maternal education program based on the temperament theory, the experimental group did not significantly decrease in scores for rejective parenting behaviors in comparison to the control group(t=-1.32, p=.19). CONCLUSION: A maternal education program based on the temperament theory is a useful intervention to decrease perceived children's behavior problems.

In this study, 20 students in C university were selected by control group and 14 shift work nurses working in C university hospital by test group It took part in case of day shift(8AM-4PM), evening shift(4PM-12MN), and night shift(12MN-8AM) to know a urinary 17-OHCS and free cortisol changes which works in a rapidly rotating shift work system. The working team were an rest period of a day and an oberservation of an week. It obtained an urine specimen before and after work shift in 2nd day. Test group and control group of shift work compared to change of levels of urinary 17-OHCS and free cortisol of urine collected from nurses of day shift, evening shift, and night shift. The data was analyzed by t-test, paired t-test. The results are as follows. 1. Compare 8AM with 4PM in day shift. Control group increased 4.1mg at 8AM, 4.2mg at 4PM in a case of 17-OHCS(p=.84) and also test group increased a little 3.5mg at start time of work, 3.6mg at stop time(p=.97). In a case of free cortisol control group decreased 3.8microgram at 8AM, 2.4microgram at 4PM(p=.12) and test group decreased 8.3microgramat start time of work, 3.2microgram at stop time(p=.22). 2. Compare 4PM with 12MN in evening shift. Control group decreased 4.2mg at 4PM, 2.9mg at 12MN in a case 17-OHCS(p=.54), but test group increased 1.7mgat start time of work, 3.4mg at stop time(p=.07). In a case of free cortisol control group decreased 2.4microgram at 4PM, 1.9microgram AT 12MN(p=.23) and also test group decreased a little 2.6microgram at start time of work, 1microgram at stop time(p=.43). 3. Compared 12MN with 8AM in night shift. Control group increased 3.9mg at 12MN, 4.1mg at 8AM in a case of 17-OHCS(p=.79) and also test group increased 6.3mg at start time of work, 8.4mg at stop time(p=.16). In a case of free cortisol control group increased 1.9microgram at 12MN, 3.8microgram at 8AM(p=.08) and test group increased 4.4microgram at start time of work, 11.6microgram at stop time(p=.04). As a result of this study reveals that health level of nurses is decreased in a rotating shift work(2 days internal). As mentioned above, it was confirmed that the rotating shift work had influence on the health of the nurse. For it, I present the objective base data to measure the level healthy in order to extend the understanding of the physical aspects of the nurses. Moreover, it is considered that one can make use of it as an objective base data with a view to the rational management for the nursing administration.

We describe a patient with overlap syndrome in whom systemic lupus erythematosus and scleroderma were combined. The patient expired due to severe central nervous system involvernent and pneumonia. Pertinent neuropsychiatric signs of the patient included generalied seizure, impairment of recent, memory, dysarthria, mental deterioration, Balints syndrome, right sided hemiparesis and right sided central type facial weakness. Hrain MRI and cerebral angiogram slowed cerebral vasculopathy. We suggest that a long-term follow-up is necessary for the confirmation of ciagnosis of a connective tissue disease, because the evolution, transition and overlapping features among the group of connective tissue diseases may commonly occur over time.
