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.

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.

메탄올 혼합 연료가 기관 연소 성능에 미치는 영향

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.

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

Background: We studied the incidence of trauma caused by alcohol related accidents, and the effects that alcohol has on the occurrence, the extent, and the outcome to the patient. Methods: In our study we studied trauma patients excluding pediatric patients(15 years old and under) who came to the Emergency department of Korea University Medical School Anam Hospital from the 1st of January 1996 to 30th of June 1996, looked into their medical records, and studied the records in a retrospective manner. The trauma patients were devided into two groups, a) alcohol-related and b) alcohol-non-related. The two groups were then subdivided according to their sex, age, the time they came in, the anatomical part of the trauma, the mechanism of their injury, the extent of the injury, the length of their hospital stay, the length of their ED stay and were seperately compared and analyzed. Statistically, ANOVA and logistic regression analysis using SAS were used in the study and then was assessed in Chi-square analysis methods. Results: The total of the trauma patients, added up to 832 people, 577:male and 255:female. Among this sum, 163 trauma patients were alcohol related(male:127 & female:36). 115 people were in the age group of 21-40. Compared to the non-alcohol related trauma group, the alcohol-related group had more facial & scalp injuries and tended to come in the hours between 0-6 AM. The cause of the injuries were mostly by fist-fighting and suicide, compared to mostly accidental-slipping injuries in the non alcohol-related group. There were no difference in the degree of the injury(ISS) and the length of hospital stay between the two groups, whereas the length of the stay at the ED was longer to the alcohol-related trauma patients. Conclusion: Alcohol related trauma patients were mostly in their 20s and 30s, came to the hospital at a late time and the reason for their visit were mostly because of fist fighting. In the Emergency department, because prompt and correct diagnosis is quite difficult to make in this group, their ED stay tended to be longer. We can conclude that measuring the blood alcohol level of these patients, continuing the psychological therapy and educating people is needed.

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.

??同位元素에 의한 火山灰土壤內 改良牧草의 燐酸肥料 利用效率에 關한 硏究

金文哲,宋成俊,鄭昌朝 제주대학교 방사능이용연구소 1985 연구보고 Vol.1 No.-

火山灰土壤에서 orchardgrass와 ladino clover의 熔成燐肥와 燐鑛石의 利用效率을 究明하기 爲하여 野外 Pot試驗(試驗1)과 土壤內 置換成 燐酸(E-value), 可變態 燐酸(L-value) 測定을 爲해 ??同位元素를 利用하여 實驗室內 實驗(試驗2)을 施行하였다. 1. 牧草의 乾物收量은 濃暗褐色土壤과 黑色土壤에서 燐酸의 施用水準 增加함에 따라 增加되었으며 ?? 水準에서 顯著한 增加率을 나타내었다. 肥料의 種類에 따른 乾物增收 效果는 熔成燐肥가 모든 處理에서 優秀하였으나 黑色土壤에서 clover는 燐鑛石에 依해 增加效果를 나타냈다. 2. 牧草內 燐酸含量은 黑色土壤에서 施肥水準이 높아짐에 따라 有意的인 增加를 가져왔으며 濃暗褐色土壤에서는 clover의 單播 또는 混播에서 含量이 높아지고 있었다. 牧草內의 無機物 中 Na의 含量은 禾本科에 比해 荳科가 높았으며 K의 含量은 濃暗褐色土壤이 黑色土壤에 比해 높았다. 그러나 Ca와 Mg의 含量은 肥料水準이나 草種間에 큰 影響을 받지 않았다. 3. 供試土壤에 ?? 處理後 192時間의 E-value는 黑色土壤(5,552㎎/ℓ), 非火山灰土壤(1,125㎎/ℓ), 濃暗褐色土壤(801㎎/ℓ)의 順位였다. ??의 土壤吸着率은 黑色土壤에서 處理後 4日에 100%로 가장 빨랐고 濃暗褐色土壤과 非火山灰土壤에서 서서히 이루어져 處理後 8日에 各各 70% 및 80%의 燐酸이 土壤에 吸着되었다. L-value는 모든 土壤에서 clover가 orchardgrass보다 높았으며 熔成燐肥의 施用은 禾本科에서, 燐鑛石은 clover의 L-value를 높여 주었다. The growth responses of Dactylis glomerata and Trifolium repens to Fused-P and Rock-P were compared on the brown and black volcanic grassland soil in the outdoor pot experiment (Experiment 1). The E-value (Exchangeable value) of two soil types and L-value (Labile phosphorus value) measurements. using ?? tracer for P-uptake by two pasture species, were determined (Experiment 2). 1. Dry matter yield of orchardgrass and ladino clover on brown and black soil was increased according to level of fertilizer applied. There was marked increase in dry matter yield at the application rate of ?? per hectare. Influence of fertilizer on dry matter yield showed that Fused-P was more effective in all treatments with the exception of black soil with Rock-P. 2. The phosphorus content in the plant increased significantly according to the level of fertilizer applied on black soil. A similar tendency was observed in clover when sown singly or mixed on brown soil. Clover contained more Na than orchardgrass and the K content in the plant was higher in plant grown in brown soil than in black soil. No significant changes in content of Ca and Mg in the plant occured even different levels of fertilizer were used. 3. Exchangeable value (E-value) at 192 hours after ?? treatment was descending order, black soil ; 5552㎎/ℓ, non-volcanic soil ; 1125㎎/ℓand brown soil ; 801㎎/ℓ. Rapid P-binding kinetic in the soil solution was detected in the black soil (100% absorptive P within 4 days) and slow P-binding was observed in brown and non-volcanic soil with 70% and 80% absorptive P within 8 days of treatment respectively. L-value of pasture species was greater in orchardgrass than in clover on all soil types. It appears that Fused-P was more effective in the improvement of L-value of grass and Rock-P was more effective in the improvement of L-value of grass and Rock-P was influenced more by the L-value of clover.
