The purpose of this study is to provide professional and amateur golfers with the basic guide to prevent injuries when playing golf. In order for that, the researcher has first researched the individual background of golfers and the parts, forms, and causes of injuries that they have according to their level of function. And also the researcher has taken a survey from professional and amateur golfers living in Seoul, Kyung-gi, and In-cheon in 2003. In order to compare and analyse these information gathered from each golfers about the injuries, questionnaires have been arranged on the basis of the studies of Batt(1992), Lee(1996), Roh(1996), Lee(1997), and Park(1998), Lee(2002). The appropriateness and validity of the contents of these questionnaires were verified after taking a preliminary test choosing each 20 of the professional and amateur golfers. Therefore, this source of questionnaires is believable with its high reliability. The statistic method in this study is frequency Analysis and x test. The results are as the followings. Injuries occur more to professional golfers than amateur golfers. And also they often have the skin injury and muscular injury because of the pressure they get to win the game doing over-exercise.

We consider a step stress life testing which is deviced for a two-component parallel system with the considerable long life time. The purpose of this paper is to suggest an optimal time for changing the stress when the simple step stress life test is carried out. The life distribution is assumed as the ACBVE by Block and Basu(1974) and the expanded CE model is suggested for the bivariate case. The criterion for optimality is to minimize the variances of the maximum likelihood estimators of the mean life times under the normal stress.

Splanchnic neurolytic block(SNB) with alcohol improves the management of pancreatic cancer pain. Adverse effects of alcohol SNB which include regional pain, hypotension, diarrhea, and acute alcohol intoxication are common, but acute hepatitis caused by alcohol neurolytic block is rare. A 63-year-old patient with pancreatic head cancer and liver metastasis had complete pain relief after both retrocrural tansdiscal SNB with 100% alcohol 10 ml. But, 1 day later, liver function test showed a high elevation in the aspartate aminotransferase (AST, 2182 IU/L) and alanine aminotransferase (ALT, 1807 IU/L). The patient had slight jaundice, general weakness, chilling, nausea and vomiting after SNB. Both AST and ALT decreased to 46 and 119 IU/L within 10 days with only supportive therapy. But, 19 days later, the patient died due to pneumonia. Our case illustrates the importance of clinical surveillance especially in patient with hepatic disease after alcohol SNB.

The golf industry is growing fast with increasing leisure time and income, and changing preference of leisure sports. Therefore, to development golf industry, it is time to make a managing alternative based on service industry, understanding consumer satisfaction factors, and overcoming competition among competitors. As preceding study for the overall golf industry, this study is focused on the golf training center service. The purpose of this study is to get a practical and theoretical suggestion by examining closely how the service quality can effect the relationship between the service quality factors perceived by customers and the level of the satisfaction by customers, focusing on the service offered by the golf training center. This paper was based on data which were collected from assessment of customers who visited the golf training center with self-administered structured questionnaire. In order to accumulate the data necessary for this study, the collected data is run by STATISTICA,

Culex pipiens pallens 모기의 난성숙에 관한 연구

姜奭熙,이승훈 성균관대학교 기초과학연구소 1986 論文集 Vol.37 No.2

본 연구에서는 Culex pipiens 모기의 난성숙에 대한 Egg development neurosecretory hormone(EDNH)의 영향과 방출시기를 decapitation을 통한 in vitro fat body incubation과 rocket immunoelectrophoresis 방법에 의해 합성된 난황단백질의 정량과 follicle cell의 성숙정도를 측정하는 방법으로 조사하였다. C. pipiens를 흡혈 후 30분에 decapitation 하였을 때 follicle cell의 성숙은 25% 정도의 모기에서 일어났으며, 흡혈 후 1 시간에 decapitation한 모기에서는 90% 이상의 모기에서 난성숙이 일어났다. A. atropalpus 에서는 우화 후 6시간 이전에 decapitation하였을 때 follicle cell의 성숙이 일어나지 않았다. Decapitation후 in vitro fat body incubation에 의한 ^3H-protein과 ^3H-vitellogein의 정량결과에서도 C. pipiens는 흡혈 후 30분에 decapitation한 모기에서 난황단백질의 합성이 일어났다. 또한 흡혈 후 1시간에 decapitation한 모기에서는 12시간에 decapitation 한 모기와 비슷한 정도의 난황단백질의 합성이 일어났다. Decapitation 후 rocket immunoelectrophoresis 방법으로 난소내에 축적된 vitellin과 지방체내의 vitellogenin을 정량한 결과 흡혈 후 30분에 decapitation한 모기에서는 흡혈 후 18시간 지난 정상모기의 난소와 유사한 양의 vitellin이 축적되었으며, 흡혈 후 1시간에 decapitation한 모기에서는 흡혈 후 24시간 지난 정상모기의 난소와 유사한 양의 vitellin이 축적되었다. 또한 흡혈 후 30분에 decapitation한 모기의 지방체 내에서 10㎍ 이상의 vitellogenin이 합성된 것으로 관찰되었다. 이상의 결과는 흡혈 후, 또는 우화 후 6시간 이후부터 EDNH의 방출이 시작되는 것으로 알려진 A. atropalpus나 A. aegypti 모기와는 달리 C. pipiens 모기에 있어서는 흡혈 후 30분 정도만 되어도 뇌로부터 EDNH의 방출이 시작되어 난성숙에 필요한 난황단백질 합성의 시작을 자극하는 것으로 여겨진다. Synthesis of vitellogenin in the anautogenous mosquito, Culex pipiens pallens was examined by incubating the fat body in vitro. Vitellogenin synthesis began to occur at 6 hours after blood feeding, reached at maximum level by 24 hour, and was completed by 45 hours. Ovarian uptake of yolk was examined by measuring the amount of egg vitellin by rocket immunoelectrophoreisis. Ovarian vitellin level began to rise at 12 hour post blood meal and continued for up to 60 hours. Decapitation within 10 minutes after blood meal completely blocked vitellogenin synthesis by the fat body. When decapitation was performed at 1 hour post blood feeding, more than 90 percent o female produced mature eggs. These results are different from that of Aedes aegypti in which the critical period was found to be 6 hours post blood meal.

We have proposed a surface-micromachined new microflow sensor to resolve the problems of poor thermal isolation and low sensitivity inherently in typical thermal flow sensors. A membrane of insulating films on a vacuum cavity supports a n'-poly heating resistor and two bidoped poly-Si thermophiles. We have investigated on heat-transfer characteristics of the sensor microstructure with the Sum-depth cavity of 100x100 μm^(2) by a two-dimensional numerical simulation as a function of the inside pressure of the cavity. As a result, the microstructure with the vacuum cavity shows better themal isolation effects than that of the air cavity.
