The employees could draw job engagement and innovative behavior through the consistency of perceived organization, job, and supervisor, which could have positive effects on organizational performance, so the fit becomes a very important element for companies. Thus, this study verified the influence relations of person-environment fit, job engagement, and innovative behavior, targeting total 298 employees working for five star hotels in Seoul region. In the results of this study, the person-organization fit and person-job fit of person-environment fit had significantly positive(+) effects on job engagement while the person-supervisor fit did not have significant effects on it. Also, the job engagement had significantly positive(+) effects on innovative behavior. Eventually, as the personal characteristics of employees are highly fitter with organizational culture, operating methods, and job goals of hotel, the job engagement gets higher. This is led to creative work attitude such as creation of innovative ideas.

The purpose of this research is to identify the factors that will influence on the successful performance of outsourcing in the Korea hotel industry. The findings and implications can be summarized as follows: First, it was found that the higher the service quality of vendor, the higher the benefits from outsourcing and the sincerer of the partnership between hotel vendor and its outsourcer, the higher the benefits from outsourcing. Second, the detailed condition of outsourcing contract between outsourcer and external supplier on the level of service quality and its evaluation, penalty in case of breaking the contract, and adaptability to sudden change surrounding the contract circumstance did not have meaningful effect on performance of hotel outsourcing. Third, in the results of general questionnaires of outsourcing that saving labor costs and reducing its expenses marks in the highest rank at the purpose of introduction of outsourcing in hotels and the effective benefits of cost saving is also marked in the highest rank at the most important element of choosing vendor. Fourth, deterioration of service quality marks the highest rank in a demerit of outsourcing in hotel industry and selecting the best supplier marks in the highest rank for successive element of outsourcing in hotel industry.

Postoperative pain is now regarded as controllable thing, further one that must be controlled, not as inevitable one no longer. In according to increasing need of pain control, efforts that would maximize the analgesic effects and minimize the undesirable effects are in process. To obtain these, the development of new ideal drugs and more accurate clarification of pain mechanism, improvement of preexisting pain control systems will be needed. Furthermore, if there would not necessary additional manpower or instruments or delicate skill, it would be better. So authors conducted this study to examine the influence of timing of connection with intravenous PCA(pain controlled analgesia) equipment to pain control by consuming amount of rescue analgesics and change of vital signs during immediate postoperative periods. Objects are those who were going to have an elective operation expected during less than three hours and ASA class 1 or 2. Among those who applied to take PCA after their operation and were from twenties to sixties and who would be expected operation in upper abdomen or chest were excluded. Patients were divided into three groups, A, B and C. Group A started to control pain by taking PCA before the operation stimulation (skin incision) after anesthetizing, group B took it for taking an anesthetic when the operation was getting over, and group C took it right after when they were brought to the recovery room. We measured blood pressure and heart rate every five minutes during 30 minutes after when they were brought to the recovery room. Pain was scored to three degree from zero to three. When the score is more than 1, we gave them intravenous nalbuphine 5 mg. Ten minutes later, pain score was measured repeatedly and if the score is more than 1, we gave them nalbuphine 5 mg again, and repeated it ten minutes later. We recorded the amount of nalbuphine during the time they were in the recovery room, and the side effects during that time. We also asked about whether they felt pain or not when they got out of the recovery room and recorded as yes or no. There were no statstically significant differences in three groups on the change of blood pressure and heart rate, and the time that takes for regain of their consciousness at the recovery room. but there were statstically significant differences in the amount of nalbuphine as rescue medicine and whether they felt pain or not when they got out of the recovery room between group A and C. In group A, less rescue medicine were consumed and less patients felt painful when they got out of the recovery room in compaing to group A. Requirement of analgesics could be reduced in immediate postoperative period by initiating and continuing pain control before operation stimulation was beginning and it was possible without extra bolus dose.

Background : Mass casualties from organophosphrous inhalation die from respiratory depression. Gas supplies and equipment are limited for mechanical ventilation of multiple subjects. Endobronchial insufflation of air (EIA) requires only a compresssor and airway catheters. We examined clinical usefulness of EIA in a model of apnea produced by tetrodotoxin (TTX) infusion. Methods : Five anesthetized dogs were applied the conventional mechanical ventilation (CMV) while 12 mcg/kg TTX was infused IV over 90 min to produce apnea. EIA at 1 L/kg/min was delivered through a 35 cm long 0.8 cm I.D. catheter with a forked end placed astride the carina. Measurements of cardiovascular and respiratory function were made after TTX (time=0) on CMV, and then serially for 4 hours of EIA. Results: All dogs survived through 4 hours study. PaO2 decreased significantly within 30 min and then slowly increased significantly after 60 min. PaCO2 increased significantly within 30 min and decreased significantly after 60 min. HR increased significantly after 20 min and MAP increased significantly after 60 min. Mean SD of PaO2, PaCO2, pHa, SaO2, cardiac output, mean pulmonary pressure, mean arterial pressure, systemic vascular resistance, central venous pressure and Qs/Qt are shown in table. Spontaneous respiratory efforts slowly returned after 45 min of EIA and resulted in the improvement of gas exchange. Conclusion : EIA is a field ventilatory technique useful when other equipment may not be available. The airway catheter can be placed by cricothyroidotomy. EIA supports life and produces normal survivors in apneic dogs. (Korean J Anesthesiol 1998; 35: 599∼606)

복강경 담낭절제술 환자에서 Propofol마취와 Enflurane 마취에 따른 수술후 간 기능 변화의 비교

오수원,우영철,구길회,김석주 대한마취과학회 1999 Korean Journal of Anesthesiology Vol.36 No.2

Background : Recently, using propofol as intravenous anesthetic agent is increasing. And it is known that propofol has little effects on liver function even after long operation such as plastic surgery. But its effect on liver functon after hepatobilliary operation which may damage liver was not studied. Thus, authors carried out this study to evaluate the effect of propofol on liver function by comparing with enflurane in the patients who had laparoscopic cholecystectomy. Methods : Patients's anesthesia records and hospital charts from January 1994 to June 1996 were anlaysed retrospectively. Three hundred and thirty three patients who had normal liver function preoperatively and had no complications during and after operation were selected. They were divided into two groups ; propofol group (n=191) and enflurane group (n=142). The preoperative values of aspartate aminotransferase (AST), alanine aminotransferase (ALT) and alkaline phosphatase (ALP) were compared with those of 1 and 3 days after operation. Results : One day after operation, both propofol and enflurane group showed significant increase in AST and ALT (p<0.05) and decrease in ALP (p<0.05). But there was no difference between two groups. Conclusion : Concerned to liver function, propofol is as useful as enflurane to the patients who scheduled for laparoscopic cholecystectomy. (Korean J Anesthesiol 1999; 36: 279∼285)
