조직시민행동의 이론적 고찰 : 호텔산업에의 적용성을 중심으로
하헌국,김서연 동국대학교 관광산업연구소 2000 관광·호텔경영연구 Vol.2 No.1
In this study, literature on employee citizenship performance was reviewed. This review provides justification for the theoretical reliance on a recent conceptualization of citizenship performance derived from political philosophy. Further, it comprises the relevance of understanding the citizenship performance of contact employees and developing a citizenship measure specifically for this unique organizational position. It also includes the need for empirical research on the relationship between contact employee citizenship and service effectiveness. The next section reviewed literatures on citizenship rights and responsibilities and social exchange. Importantly, this review provides a basis for the inclusion of the independent variables in the future empirical study. It also provides the theoretical background for two competing theoretical models of citizenship performance. The last section of the literature review discussed relevant conceptual and empirical research on each of the independent variables in the future empirical study. This review provides an overview of previous research on each independent variable and further presents evidence concerning two competing theoretical models.

The residual study of pesticide has been used in various areas, such as food safety, environmental protection, establishment of tolerance, and explaining the pathway and reaction mode of pesticides, and its importance was expected to increase further more. The aspect of food safety, the pesticide residue survey have been practiced at many organizations, but there were no verification of analytical results at present. In this experiment, we focused on instrumental stability, including response of each instrument and the recovery ratio of each organization's method. As samples for this experiment, we prepared cucumber and sesame, and chose 4 pesticides (bifenthrin, chlorpyrifos, diazinon, and ethoprophos), which were mostly detected from pesticide residue survey and widely used for each crop. The standard deviation of peak areas in the chromatogram of each pesticide were under 1.212 %, so it showed that most instruments were stable. The relationship of recovery ratio of each organization were over 0.996 for every pesticide and each organization. Finally, the analytical results for pesticide residue from each participated organization were not statically significant and we could put confidence in the result from each organization.

Despite growing interest and a recent surge in papers, the role of autophagy in glucose and lipid metabolism is unclear. We produced mice with skeletal muscle–specific deletion of Atg7 (encoding autophagy-related 7). Unexpectedly, these mice showed decreased fat mass and were protected from diet-induced obesity and insulin resistance; this phenotype was accompanied by increased fatty acid oxidation and browning of white adipose tissue (WAT) owing to induction of fibroblast growth factor 21 (Fgf21). Mitochondrial dysfunction induced by autophagy deficiency increased Fgf21 expression through induction of Atf4, a master regulator of the integrated stress response. Mitochondrial respiratory chain inhibitors also induced Fgf21 in an Atf4-dependent manner. We also observed induction of Fgf21, resistance to diet-induced obesity and amelioration of insulin resistance in mice with autophagy deficiency in the liver, another insulin target tissue. These findings suggest that autophagy deficiency and subsequent mitochondrial dysfunction promote Fgf21 expression, a hormone we consequently term a 'mitokine', and together these processes promote protection from diet-induced obesity and insulin resistance.

On department of anesthesiology, Hanyang university hospital, we used to the Diascan-S for portable blood glucose monitoring during surgery with anesthesia. So, we try to know about the accuracy, the precision and the specificity of that instrument. Period to check for blood glucose was devided to 3 groups that are on just after induction, the operation of main lesion, the end of surgery and we compared to the blood glucose level by the Diascan-S and the standard reference test. Central laboratory used glucose oxidase method to check blood glueose as the standard reference test. Thereafter we got the conclusions as follow. 1) We had got to good correlation between the blood glucose level by Diascan-S and the stan-dard reference test. (Y=65+0.64X, correlation coefficiency 0.58, p value; 0.0000) 2) When the blood glucose levels had devided as below from l00 mg/dl, 100 mg/dl to 150 mg/ dl and above 150 mg/dl, we only got to good correlation blood glocose level by Diascan-S and the standard reference test from 100 mg/dl to l50 mg/dl. (Y=11+2.5X, correlation coefficieny ; 0.51, p value ; 0.0000) 3) When we had tested for blood glucose on ]ust after anesthesia induction and the operation on main lesion, the end of surgery, the results of each period have a good correation each other by Diascan-S and the standard reference test. (a) Just after anesthesia induction Y = 51+0.50X, correlation coefficiency 0.52, p value 0.0000 (b) Operation for main lesion Y = 80+0.38X, correlation coefficiency 0.45, p value 0.0000 (c) End of surgery Y = 61+0.54X, correlation coefficiency ; 0.62, p value 0.0000 4) The condition of instrument had devided to two conditions of Diascan-S as was calibrated by technician reqularly or not, got to more confident correlation coefficiency when the Diascan-S had calibrated by technician reqularly. (a) had calibrated reqularly Y = 40+0.62X, correlation coefficiency 0.65, p value: 0.0000 (b) had not calibration Y = 77+0.42X, correlation coefficiency ; 0.36, p value: 0.0026 By above results, we got conclusions that portable glucose monitoring instrument(Diascan-s) can use to know to change of blood sugar during anesthesia. And then, if we got the result of blood glucose level as belows 100 mg/dl or above 150 mg/dl when used Diascan-S, should try to test again and must compared to standard reference test of central laboratory. Diascan-S must be calibrated by technician reqularly if we try to get more accurate results of blood glucose by Diascan-S.

The Pentaspan is a high molecular weight(250,000), hyperosmolar(320 mOsm/l) colloid solution and blood volume expander in clinical practice. Many researches revealed the decreasing of systemic vascular resistance and pulmonary vascular resistance after Pentaspan administration in vivo. Some colloid solution is contraindicated in acute renal failure. We tried to confirm the direct effects of the Pentaspan and its mechanism on the abdominal aorta and renal artery in vitro. The rat abdominal aorta and renal artery were precontracted with norepinephrine(10^(-7) M/l) in 50 ml Krebs solution and 5 ml Pentaspan was infused. Ten mininutes after, changes of the vascular tones were obtained. The results were as follows. 1) The vascular tones were significantly decreased in both vessels. 2) Abdominal aorta group, renal artery group and with or without endothelium group were not significant different each other. 3) The vascular tones were not affected by with or without endothelium, indomethacin and methylene blue pretreatment. Smooth muscles were induced relaxation by the Pentaspan infusion and the relaxation were not dependent to endothelium derived relaxing factor, prostanoid and cyclic guanosinemonophosphate

Background: The effective use of habitats is essential for the successful adaptation of a species to the local environment. Although habitats exhibit a hierarchical structure, including macro-, meso-, and microhabitats, the relationships among habitats of differing hierarchy have not been well studied. In this study, we studied the quantitative measures of microhabitat use of Gekko japonicus from three field populations in Japan: one at Tsushima Island, one at Nishi Park, Fukuoka, and one at Ohori Park, Fukuoka. We investigated whether land cover type, a higher hierarchical habitat component, was associated with quantitative microhabitat use, a lower hierarchical component, in these populations. Results: The substrate temperature where we located geckos (SubT) and the distance from the ground to the gecko (Height) were significantly different among the three populations. In particular, SubT on Tsushima Island was lower than it was in the other two populations. Irradiance at gecko location and Height were significantly different among the land cover types. In particular, Height in evergreen needleleaf forest was significantly lower than that in deciduous broadleaf forest. Furthermore, significant interactions between population and land cover type were observed for the SubT and Height variables. Conclusions: The quantitative measures of microhabitat use of G. japonicus varied with population and land cover type, which exhibited significant interaction effects on microhabitat use variables. These results suggest that higher hierarchical habitat components can affect the quantitative measures of lower hierarchical microhabitat use in nocturnal geckos.

The Department. of Anesthesiology of Hanyang University had a case of operation for pheo- chromocytoma. For the operation of pheochromocytoma, used to prazosin for preoperative treatment of hypertension and used to enflurane as inhalational anesthetic, treated with sodium nitroprusside for severe elevation of blood pressure during operation, used to vecuronium for neuromuscular blocker. Also we tried to get the knowledge about the variation of catecholamine concentration in blood through operation. As we used to the other drugs with adequate amount of fluid without any other complication in this operation we reported here with other references and our experience of a case of operation for remove of pheochromocytoma.
