The organization of nursing department Significantly effects the hospital management. Especially, The head nurse is one of the most important position because head nurse is a first-line manager in the hospital level, a middle manager in nursing service organizations level and the top manager in each nursing unit level. This study was attempted to show the ideal model and nile by compare head nurses' role perception with staff nurses' role expectation according to two types of hospital. The survey was conducted among 94 head nurses and 233 staff nurses who are working at 5 different University Hospitals over 600 beds and 93 head nurses and 218 staff nurses Who are working at 12 different General Hospitals between 100∼300 beds in Seoul. The data was collected in a period from 8th September to 13th October in 1989 and the instrument used for this study was based on Han's one and reffered back to many literary sources and revised. The collected data was analysed by computer using S.P.S.S. program as a Mean, Percentage, Cronbach's alpha, Chi-Square, t-test and ANOVA. 1. The study was compared to the difference of the two subject group's general characteristics according to a type of hospital. As a relult, there were significant differences in age, educational background and career. 2. This Study was compared to the difference of the two subject group's role perception and role expection about each question according to a type of hospital. The result of this comparisons as follows : First, These were the most important issue between both groups : “Head nurse has to know about her staff's events and problems and then help them to solve that promptly.” Second, These were the least important issue between both groups : “Head nurse has an interview with patient's family and visitors”, “Head nurse is interested in her staff's privacy.” 3. This study was compared to the differences of each role areas according to a type of hospital. As a result, there were no significant differences both two subject groups except nursing manager role in staff nurses' group(t＝-2.893, df＝449.0, p＝0.004). 4. This study was tested to the difference of the two subject groups according to general characteristics. As a result, All of that there were no significant differences.

In this study, the Slab Ocean Model (SOM) is coupled with an Atmospheric General Circulation Model (AGCM) which developed in University of Kangnung based on the land surface model of Biosphere-Atmosphere Transfer Scheme (BATS). The purposes of this study are to understand radiative role of clouds considering of the atmospheric feedback, and to compare the Clouds Radiative Forcing (CRF) come from the analyses using the clear-cloud sky method and CGCM. The new CGCM was integrated by using two sets of the clouds with radiative role (EXP-A) and without radiative role (EXP-B). Clouds in this two cases show the negative effect $-26.0\;Wm^{-2}$ of difference of radiation budget at top of atmosphere (TOA). The annual global means radiation budget of this simulation at TOA is larger than the estimations ($-17.0 Wm^{-2}$) came from Earth Radiation Budget Experiment (ERBE). The work showed the surface negative effect with $-18.6 Wm^{-2}$ in the two different simulations of CRF. Otherwise, sensible heat flux in the simulation shows a great contribution with positive forcing of $+24.4 Wm^{-2}$. It is found that cooling effect to the surface temperature due to radiative role of clouds is about $7.5^{\circ}C$. From this study it could make an accurate of the different CRF estimation considering either feedback of EXP-B or not EXP-A under clear-sky and cloud-sky conditions respectively at TOA. This result clearly shows its difference of CRF $-11.1 Wm^{-2}$.

In the more than one decade, studies of organizational citizenship behavior(OCB) have increased continuously, research on the role of job satisfaction and organizational commitment upon the relationships between OCB and Job characteristics, however, is very scarce. This study analyzed comprehensively existing studies of OCB, designed a model of mediating role of behavioral performance(job satisfaction, organizational commitment), and generated three hypotheses inherent in the model. To design the model and generate the hypotheses, this study conducted a comprehensive literature survey on OCB. To test the hypotheses, this study collected data from 847 employees at 12 large general hospitals in Pusan area through a questionnaire survey and conducted the three step mediated regression analysis using the SAS-PC Package. Conclusively, job characteristics tend to be the most influential antecedents affecting not only through mediating factors but also directing to OCB. These and other major findings from this study imply that existing American studies may be applicable the Korean organizations and that this study may complement the deficiencies of the existing studies.

Objective: Adipose tissue is no longer considered as an inert storage organ for lipid, but instead is thought to play an active role in regulating insulin effects via secretion adipokines. However, conflicting reports have emerged regarding the effects of adipokines. In this study, we investigated the role of adipokines in glucose metabolism and insulin sensitivity in obese Bama mini-pigs. Methods: An obesity model was established in Bama mini-pigs, by feeding with high-fat and high-sucrose diet for 30 weeks. Plasma glucose and blood biochemistry levels were measured, and intravenous glucose tolerance test was performed. Adipokines, including adiponectin, interleukin-6 (IL-6), resistin and tumor necrosis factor alpha ($TNF-{\alpha}$), and glucose-induced insulin secretion were also examined by radioimmunoassay. AMP-activated protein kinase (AMPK) phosphorylation in skeletal muscle, which is a useful insulin resistance marker, was examined by immunoblotting. Additionally, associations of AMPK phosphorylation with plasma adipokines and homeostasis model assessment of insulin resistance (HOMA-IR) index were assessed by Pearce's correlation analysis. Results: Obese pigs showed hyperglycemia, high triglycerides, and insulin resistance. Adiponectin levels were significantly decreased (p<0.05) and IL-6 amounts dramatically increased (p<0.05) in obese pigs both in serum and adipose tissue, corroborating data from obese mice and humans. However, circulating resistin and $TNF-{\alpha}$ showed no difference, while the values of $TNF-{\alpha}$ in adipose tissue were significantly higher in obese pigs, also in agreement with data from obese humans but not rodent models. Moreover, strong associations of skeletal muscle AMPK phosphorylation with plasma adiponectin and HOMA-IR index were obtained. Conclusion: AMPK impairment induced by adiponectin decrease mediates insulin resistance in high-fat and high-sucrose diet induction. In addition, Bama mini-pig has the possibility of a conformable model for human metabolic diseases.

This paper proposes and examines the economic impact of infrastructure improvement on the San-En-Nanshin region in the Chubu area of Japan. We develop a single transportation computable general equilibrium (CGE) model for each subregion within the San-En-Nanshin region. The explicit modeling of the transportation infrastructure is defined based on interregional commuting flows and business trips, considering the spatial structure of the San-En-Nanshin economy. A CGE model is integrated with an interregional transportation network model to enhance the framework's potential for understanding the infrastructure's role in regional development. To evaluate the economic impact of transportation improvement, we analyze the interrelationship between travel time savings and regional output and income. The economic impact analysis under the CGE framework reveals how transportation facilities and systems affect firm and household behavior and therefore induce changes in the production and consumption of commodities and transportation services. The proposed theoretical model was tested by using data from the 2005 IO tables of each subregion and the 2006 transport flow dataset issued by the Ministry of Land, Infrastructure, Transport, and Tourism in Japan. As a result, the paper confirms the positive effect of transportation investment on the total output and income of the studied region. Specifically, we found that while economic benefits typically appear in urban areas, rural areas can still potentially benefit from transportation improvement projects.

The importance of the role of plastic spin in the rate-dependent response of materials at large deformations is the main objective of this work. After a brief presentation of a general consitutive framework for visco-rigid plasticity at large strains an isotropic/kinematic hardening and a visco-rigid plastic model are used to analyze the stress-strain response under simple shear. A clear understanding of the role of plastic spin is achieved by obtaining numerical analyzed results for different stress values in which the plastic spin consititutive parameters interrelaste with the strain rate and other more conventional model constants, Especially this paper is concerned with introducing behaviors of Al7075
