문제혁,이상준,박정덕 대한산업의학회 2007 대한직업환경의학회지 Vol.19 No.1

목적: 대사증후군은 심혈관계 질환의 이환과 이로 인한 사망률을 증가시키는 것으로 알려져 있으며, 비만, 고 중성지방혈증, 저 HDL-콜레스테롤혈증, 고혈압, 공복 시 고혈당 등에서 3개 항목 이상을 만족한 경우로 정의된다. 간기능 검사 중 γ-GTP는 간세포 손상에 대한 생체지표로 흔히 사용되는 검사이며, 고혈압, 제 2형 당뇨 및 뇌졸중과도 관련이 있음이 밝혀져 있다. 이번 연구에서는 일개 철강 사업장내 근로자들의 대사증후군의 유병률과 위험요인 및 대사증후군과 γ-GTP와의 관련성을 알아보았다. 방법: 수도권 소재 일개 철강 사업장 남자 근로자 1,604명을 대상으로 대사증후군의 구성요소(체질량지수, 중성지방, HDL-콜레스테롤, 수축기와 이완기 혈압, 공 복 시 혈당)와 γ-GTP, 교대근무 여부, 음주력, 흡연력, 운동 여부 및 가족병력 등을 조사하여 분석하였다. 결과: 일개 철강사업장근로자에 있어서 대사증후군의 유병률은 21.3%, 연령 보정 유병률은 15.5%이었다. 대사증후군에 영향을 미치는 역학적 요인은 연령(OR: 1.063, 95% CI: 1.033-1.094), 음주(OR: 1.657, 95% CI: 1.175. 2.337) 및 흡연(OR: 1.359, 95% CI: 1.017. 1.816) 등 이었고, 교대근무는 고혈압(OR: 1.329, 95% CI: 1.038-1.700)에만 영향을 주었다. 고 γ-GTP 혈증군에서 대사증후군의 구성인자인 비만, 고 중성지방혈증, 고혈압 및 공복시 고혈당의 위험도는 각각 2.625, 3.384, 1.887, 2.406이었고, 대사증후군의 위험도는 3.345이었다. 결론: 이번 연구결과로 볼 때, 철강 사업장에서 대사증후군에 대한 적극적인 관리를 위하여 금주와 금연 등 생활행태 개선을 위한 보건교육이 요구되었고, γ-GTP가 대사증후군의 조기 색출지표로서의 가능성이 제기되었다. Objectives: This study was performed to estimate the prevalence and possible risk factors of the metabolic syndrome in steel-mill workers, and to evaluate the relation between γ-glutamyltransferase (γ-GTP) and the metabolic syndrome. Methods: The study subjects comprised 1,604 male steel-mill workers. The indices of metabolic syndrome, such as BMI, triglyceride, HDL-cholesterol, blood pressure, fasting glucose, and γ-GTP were analyzed in each subject. We collected information about demographic characteristics, behavioral patterns, such as alcohol drinking, smoking, and exercise, and family medical history through a self-administered questionnaire. Statistical analysis was done by using the chi-square test, Mantel-Haenszel trend test and logistic regression model. Results: The crude and age-adjusted prevalences of the metabolic syndrome were 21.3% and 15.5%, respectively, in the steel-mill workers. Age (OR: 1.063, 95% CI: 1.033-1.094), alcohol drinking (OR: 1.657, 95% CI: 1.175-2.337) and smoking (OR: 1.359, 95% CI: 1.017-1.816) were risk factors for the metabolic syndrome. Meanwhile, shift work showed a significant relation with hypertension (OR: 1.329, 95% CI: 1.038-1.700), but not with other metabolic syndrome components. However, tenure, exercise and family medical history were not significant factors for the metabolic syndrome in this study. The risk ratio of the metabolic syndrome (OR: 3.345, 95 % CI: 2.534-4.416) and its components, such as obesity, hypertriglyceridemia, hypertension and hyperglycemia, were higher in the high γ-GTP group (≥63 IU/Ɩ ) than in the controls (<63 IU/Ɩ ). Conclusions: These results confirm the need for health education to control the metabolic syndrome by improving behavioral patterns, such as alcohol drinking and smoking, in factory workers. In addition, it is suggested that γ-GTP might be a useful candidate in screening for the metabolic syndrome.

Turbine blade is subject to force of three type; torsional force by torsion-mount, centrifugal force by rotation of rotor and cyclic bending force by steam pressure. Cyclic bending force of them is main factor on fatigue fracture. SEM fractography show micro-crack width is not dependent on stress intensity factor range. Especially, fatigue striation does not exist on SEM photograph. To clear out fracture mechanism of turbine blade, nanofractography is needed on 3-dimensional crack initiation and crack growth with high magnification. Fatigue striation partially exists on AFM photograph. Therefore, to find fracture reason of torsion-mounted blade in nuclear power plant, we estimate the relation between stress intensity factor range and surface roughness measured by AFM and predict load amplitude ΔP applied to turbine blade

The importance of creating effective advertisements which can be helpful to improve brand value is ever increasing. The purpose of this study is to investigate effect of creative factor(message factor, model factor, creative/execution factor) in order to help creating advertisements. This study hierarchically analyzed the structural model about the effects of ad creative factors on advertisement attitude and purchase interest through advertisement. Message factor is constructed of understanding, persuasiveness, and uniqueness. Model factor is composed of credibility, attractiveness, and fit. Creative/execution factor is composed of novelty and elaboration & synthesis. Based on this concept, we made construct on 2 step Hierarchical Advertising Effectiveness Model(specific creative factor → overall creative power → ad effect). This Model has been developed in an effort to transcend varied limitations of other previous studies. Consequently, the practical value of this model is highly expected. The major findings from this model are summarized as follower: All of the three creative factors is hierarchically influenced on Ad Power(advertisement attitude and purchase interest) in every product class. Creative/execution is the most influential creative factor in this study. Theoretical and marketing implications, limitation and direction for future research are discussed.

문성준 三陟大學校 1997 論文集 Vol.30 No.1

It is needed to improve the evaporation phenomena and the characteristics which change material properties when we use methanol for gasoline engine because it has the more vapor containing heat than that of gasoline engine and also to solve problems of starting and responding ability. This study analyzed engine performance and combustion efficiency in case of adding methanol to the existed gasoline fuel. It is shown that the mixed fuel of 10% methanol has almost the same response with gasoline and is also shown that when we add more methanol to the fuel, the ignition time should be movel more to the top dead center for the easy ignition because more methanol to the fuel lead to quicker ignition.

Comparison of Epidural Ropivacaine and Bupivacaine in Patients Undergoing Lower Extremity Surgery Chul-Jun Mun, M.D., Sang-Gon Lee, M.D., Jong-Suk Ban, M.D. and Byung-Woo Min, M.D. Department of Anesthesiology, Fatima Hospital, Daegu, Korea Background: Ropivacaine is an amide local anesthetic structurally related to bupivacaine. A ran-domized, double-blind study was performed to compare the clinical effectiveness of ropivacaine and bupivacaine in patients undergoing lower-extremity surgery. Methods: Forty-nine patients (ASA Ⅰ-Ⅱ) were randomized to receive 15 ml of 0.5% ropivacaine or bupivacaine. Twenty patients received 15 ml of ropivacaine and 20 patients received 15 ml of bupiva-caine at the L3,4 or L4,5 interspace. Parameters measured were the onset time, duration and spread of sensory block, the onset time, duration and degree of motor block, the quality of anesthesia and the heart rate and blood pressure profile during the block onset. Results: Demographic characteristics were similar among the groups. Seven patients were excluded from the study due to technical failure of the block, two patients were excluded due to insufficient data. The onset and duration of analgesia at T10 dermatome (mean ?? SD) was 18.9 ?? 7.0 minutes and 187.5 ?? 34.6 minutes respectively for ropivacaine, and was 15.2 ?? 8.8 minutes and 187.8 ?? 40.0 minutes respectively for bupivacaine. Maximum block height (mean ?? SD) was T6.5 ?? 2.0 for ropivacaine and T6.4 ?? 2.0 for bupivacaine. The incidence of complete motor block (Bromage scale 3) was low in the ropivacaine group, being 3/20 for ropivacaine and 12.20 for bupivacaine. Conclusions: The sensory blockade profile of ropivacaine, administered epidurally, is similar to that obtained with an equal dose of bupivacaine. However motor blockade with ropivacaine is less intense, less frequent, and of shorter duration than with bupivacaine. (Korean J Anesthesiol 2001; 41: 434~438)

A posterolateral intertransverse process fusion is generally considered to be one of the most common types of lumbar fusion and a reliable procedure. It is reported that establishment of blood supply is important for nutrition as well as for formation of new bone during bone graft healing. Since the major interosseous blood supply for vascularization of autogenous bone graft is originated from the upper and lower transverse process, the one of the transverse process can he related to rate of bony union. It can be constructed that different union rate can result from the differences in transverse process areas. In this study, the area of the transverse processes of L5 were measured in normal adult. For this purpose, Ushikata area-Curvimeter (X-PLAN 360) was used. In Results, there was no significant differences in the age, but there was differences in the gender.

During anesthesia, unexpectedly endotracheal tube obstruction cause seriouscomplications which require early diagnosis and immediate management. Endotracheal tube obstruction with foreign body is rare. 74 year old man was scheduled for open lung biopsy. The patient was intubated with a 7.5 mm reinforced endotracheal tube and turned to the right lateral position. After 30 minute, signs of partial endotracheal obstruction was observed including high airway pressure and decreased end-tidal CO2. A suction catheter was not deeply advanced. A wheezing - like sound was heard. We temporarily stopped the operation and turned the patient to supine. We exchanged the tube with another one and found impacted mucous secretions at the distal tip of the tube.
