Effects of vanadate on the isometric contraction, membrane potential and its maximal rate of depolarization of rabbit ventricular papillary muscles were recorded in normal Tyrode solution and 19mM K^+ Tyrode solution. Following results were obtained: 1. Vanadate increased the isometric contractions in normal Tyrode and 19mM K^+-Tyrode solution in a dosedependent manner. 2. Vanadate increased the duration and Vmax of slow action potential. 3. Vanadate induced slight hyperpolarization of unstimulated quit preparations in normal and high K^+-Tyrode solution. 4. Effects of vanadate which were observed in K^+-depolarized preparations were reversed by diltiazem, a calcium channel blocker. It could be conciuded that vanadate has positive intropic effect by increasing Ca-current in the papillary mucles of the rabbit.

To investigate the effects of ethanol on the lipid metabolism in blood and liver, twenty one male Sprague Dawley rats had orally taken the 25% alcohol and 50% alcohol by 5g per Kg of weight during 3 weeks after the adjusting period. For the energy balance, 85% sucrose and 45% sucrose was added in control group and 25% alcohol group each. The weight was reduced by alcohol treatment according to the levels, otherwise the weight of liver and heart was little increased in alcohol groups rather than in control without significance. Moreover, RBC, WBC, hemoglobin and hematocrit were increased by alcohol treatment according to the levels without significance. Otherwise, adjusted bilirubin levels by 100g of weight was significantly increased by alcohol treatment dose dependently. Alcohol induced RBC degradation and increased circulated bilirubin because of liver damage. For blood lipid profiles, blood cholesterol was increased in 50% of alcohol group compared to that of 25% and control groups, otherwise, blood triglycerides (TG) was increased by 30% in 25% alcohol groups rather than in control but not significantly different. The hepatic lipid composition, cholesterol levels in alcohol treatment groups was lower than those in control. The hepatic TG was not influenced by alcohol treatment. The two reasons of decreasing hepatic lipids were suggested by 85% sucrose of control for energy balance more synthesized cholesterol and TG than those in 25 or 50% alcohol groups, and by cholesterol and TG could not be synthesized because of liver damage from alcohol.

본 연구는 비만도에 따른 한국인 남성 폐쇄성수면무호흡 환자의 측모 두부 방사선계측학적 특성을 파악하기 위하여 시행되었다. 이를 위하여 계명대학교 의과대학 동산의료원 수면클리닉에 수면장애를 주소로 내원하여 수면다원검사 후 치과에서 측모 두부방사선계측사진 촬영을 한 87명의 성인 환자들을 체질량지수(BMI)와 수면무호흡지수(AHI)에 따라 비비만 단순코골이군(Non-obese, simple snorers), 비만 단순코골이군(Obese, simple snorers), 비비만 수면 무호흡군(Non-obese, OSA patients), 비만 수면무호흡군(Obese, OSA patients)의 4군으로 나누어 비교하였다. 그결과, 4군 중 비만 수면무호흡군의 수면무호흡지수가 가장 컸으며, 비만 수면무호흡군보다 비비만 수면무호흡군의 하악각이 더 크고 혀 길이는 더 작았다. 또한, 비비만 수면무호흡군보다 비만수면무호흡군의 설골이 더 전하방에 위치하였고, 수면무호흡지수에 영향을 미치는 기여 인자는 비만 수면무호흡군에서는 혀 길이, 비비만 수면무호흡군에서는 설골의 후방위치였다. 이처럼 비만 수면무호흡 환자와 비비만 수면무호흡 환자의 측모 두부방사선계측학적 특성과 기여 인자가 다르게 나타나므로, 치료방법도 따라서 다르게 선택해야 할 것이다. 비만 수면무호흡 환자들에게는 먼저 체중감량이 권고되어야 할 것이고, 비비만 수면무호흡 환자들은 폐쇄부위에 따라 구강 내 장치나 Nasal CPAP (continuous positive airway pressure), UPPP (uvulopalatopharyngoplasty) 등이 추천될 수 있을 것이다. Objective: The purpose of this study was to compare the cephalometric measurements of obese and non-obese Korean male patients with obstructive sleep apnea syndrome (OSA). Methods: Eighty-seven adults who had visited the Sleep Disorder Clinic Center in Keimyung University, Daegu, Korea were examined and evaluated with polysomnography (PSG) and lateral cephalogram. They were divided into 4 groups (non-obese simple snorers, obese simple snorers, non-obese OSA patients, obese OSA patients) according to AHI (Apnea-Hypopnea Index) and BMI (Body Mass Index). Results: The obese OSA group had the highest AHI among the 4 groups. The non-obese OSA group had a significantly steeper mandibular angle and shorter tongue length than the obese OSA group. The hyoid bone of the obese OSA group was positioned anterior and inferior as compared with the non-obese OSA group. Multiple regression analysis showed that tongue length in the obese OSA group and retroposition of hyoid bone in the non-obese OSA group were significant determinants for the severity of AHI. Conclusions: From a cephalometric point of view, the obese and non-obese pateints with OSA may be characterized by different pathogeneses. Therefore, they have to be managed by individualized treatment. For the obese OSA patients, weight control must be advised as a first choice and for the non-obese OSA patients, oral appliance, nasal CPAP, UPPP and others could be chosen according to the obstructive sites.

Recently, customers for automobiles expect new models in a short life cycle. Therefore, is has been important to reduce the development lead-time. However, a traditional development system is not appropriate to meet these changes. Thus, Concurrent Engineering (CE)has been introduced to solve these problems as a key business strategy based on information technology. CE is a way of attaining three objectives simultaneously; reducing time to market, improving product quality, and lowering product costs.<br/> The purpose of this study is to recommend a CE strategy for improving the development process of Korean automotive industries. Thus, the key factors of CE and their effectiveness on the development processes are introduced, Based on that, the competitiveness of US and Japan automobile industries are analyzed, and the problems of development processes of Korean antomotive industries are investigated. Finally, a CE strategy for improving the problems are proposed.<br/>
