The purpose of study was to develop and validate Korean Sleep Scale A which can be easily administrated by nurse for a wide range of adult subjects. Dimensions of adult concept were derived by literature review. Previously developed sleep scales were also analyzed in order to develop scales items. The Korean sleep scale A was structured as a 15 item, 4 point like type scale. The Scale was tested an 298 female and male adult subjects after pilottest and content validation. The results showed reliability by internal consistency of Cronbach's alpha=75 Construct validity was tested by factor analysis and known group technique. Factor analysis showed 4 factor-sleep pattern, sleep evaluation, sleep result, and cause of sleep disturbance. Theses four factors explained 55.9% of total variance. Correlations between factors ranged from .15-.32. There was correlation among Korean Sleep Scale A score, Verran and Snyder-Halpern(VSH) Sleep Scale scale, and sleep satisfaction scale score, r= .71(p=.00), r=.51(p=.03), respectively. These study results partially support reliability, construct validity, and criterion related validity of Korean Sleep Scale A. Further validation study is required with other subjects and other settings.

To determine effects of the direction of the rotational work shifting on the circadian rhythm and adaptation of physiological and psychological components were investigated with nursing students. Two groups of seven volunteers participated as experimental subjects, and eight 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 lays), evening shift(3days), off duty(1day) and night shift(5days). and CCW(counterclockwise)-shift system rotation in the reverse direction. Urinary free cortisol and 17-hydroxycorticoster oids in the urine were measured by the solid-phase radioimmunoassay and the colorimetry methods, re spectively. Plasma melatonin was measured by radioimmunoassay. The urinary free cotisol rhythm changed to ir-regular on the evening and night shift in the CCW shift system, whereas the rhythm seems to adapt on night shift in the CW shift system. The daily rhythms of urinary 17-OHCS indicate that they are well synchronized to shift work. These results show that the rotation of shift in the CW direction is more acceptable in terms of the adaptation of hormonal rhythms. These results indicate that the CCW rotation of shift work makes it more difficult for the workers to adapt on a physiological level, and has many more negative effects on nurses when compared with the CW rotation. Thus, a clockwise rotating shift systern seems to be more desirable for the optimal health and performance of nurses.

Purpose: This study is a descriptive research study attempted to identify the job stress and positive psychological capital of clinical nurses and to identify the factors that impact job embeddedness. Methods: Data were collected from 115 nurses with over one year of clinical experience working at a 500-bed B General Hospital. The collected data were analyzed with the SPSS 27.0 program using frequency and percentage, mean and standard deviation, Independent t-test, One-way ANOVA, Scheffé test, Pearson's correlation coefficients, and multiple linear regression. Results: As a result of multiple regression analysis, hope among the sub-factors of positive psychological capital (β=0.48, p<.001), matters related to the work schedule (β=-0.23, p=.005) among the sub-factors of job stress, and conflict with doctor (β=0.20, p=.013) was found to have an impact on job embeddedness, and the explanatory power of this regression model was 52.0% (F=13.12, p<.001). Conclusion It was found that the positive psychological capital of clinical nurses has a positive impact on job embeddedness. In order to increase the job embeddedness of clinical nurses, it is necessary to develop, educate, and utilize specific intervention programs that can strengthen positive psychological capital. Efforts should be needed to prepare specific strategies for nurses to recognize the importance of hope and actively utilize positive psychological capital. In addition, it is necessary to create an organization-level working environment and continuous management to reduce the job stress of clinical nurses.

It is difficult to distinguish an islet tumor originating from heterotopic pancreas tissue from the other submucosal tumors. Although the malignant transformation of a heterotopic pancreas, including islet cell tumor, is extremely rare, it remains an important consideration in the differential diagnosis of duodenal submucosal masses. We have demonstrated the radiologic appearance and the clinical-pathologic findings of a highlighted, rare case of islet cell tumor arising from a heterotopic pancreas in the duodenal wall.

BACKGROUND: High glucose upregulates MCP-1 expression in rat glomerular mesangial cells and in human peritoneal mesothelial cells. However, the role of high glucose-induced MCP-1 on the development and progression of diabetic renal injury and peritoneal injury during peritoneal dialysis(PD) using high glucose PD solutions are not clear. Since MCP-1 was shown to upregulate transforming growth factor-beta1(TGF-beta1) and collagen expression in lung fibroblasts, the present study investigated the effects of MCP-1 on fibronectin secretion by mouse mesangial cells(MMC), human peritoneal mesothelial cells (HPMC), and human peritoneal fibroblasts(HPFB). METHODS: Synchronized cells were stimulated by different concentrations of MCP-1(0.1-100 ng/mL) or TGF-beta1(0.1-10 ng/mL) for 48 hours. Fibronectin protein secreted into the media was analyzed by Western blot analysis. RESULTS: MCP-1 up to 100 ng/mL did not affect fibronectin secretion by MMC. TGF-beta1 10 ng/mL, however, increased fibronectin secretion by MMC 2.8 fold that of control. MCP-1 up to 100 ng/mL did not affect fibronectin secretion by HPMC. But, TGF-beta1 0.1 ng/mL increased fibronectin secretion by HPMC 1.8 fold compared to control. On the other hand, MCP-1 increased fibronectin secretion by HPFB in a dose-dependent manner. MCP-1 at 1-10 ng/mL significantly increased fibronectin when compared to M199 control. 100 ng/mL MCP-1 further increased fibronectin secretion by HPFB compared to 0.1-10 ng/mL MCP-1. CONCLUSION: These results suggest a possible role for MCP-1 in the development and progression of peritoneal fibrosis and support the view that in addition to recruiting inflammatory cells MCP-1 may play a role in tissue fibrosis in other organs.
