This paper presents a comparison of attitudes between Chinese and Korean university students. Compared with Korean students, on average Chinese students do not spend as much on leisure-related products or services. However expenditure on leisure related products increrases as family income increases. Similar to Korean students, most Chinese students own mobile phones. The percentages of ownership of other multimedia devices such as PC, MP3 players, and digital camera are lowerfor Chinese students than forKorean students. Chinese students as well as Korean students prospect their generation to be better off than their parents' generation. Especially, more than half of Chinese students believe their economy will catch up with Japanese economy in 30 years. As Chinese economy grows, both Chinese and Korean students do not expect the relationship between China and Japan to improve much. Chinese 'likeness' of Korean trend is very apparent but Korean 'likeness' of Chinese trend is very minor. It is also observed that higher percentage of Chinese students like Korea than that of Korean students like China. Sexual attitudes are very similar between the two groups. They are relatively affirmative on sexual relations before marriage. Chinese students think human network is essential for getting jobs. Korean students think English proficency is the most important factor. However, Chinese students spend longer hours in practicing English and reading books than Korean students. Korean students drink alcohol much more frequently than Chinese students. Also, therate of smoking is much higher for Korean students than Chinese students. No female Chinese student said she was a smoker.

Glucose-fatty acid cycle is very important because it explains that fatty acid influences glucose level. Glucose-fatty acid cycle is the key factor to understand how endurance training which aids fat oxidation and carbohydrate stored in skeletal muscle influence mitochondria level. However, it is not certain whether glucose-fatty acid cycle influences exercising skeletal muscle of human being. As an energy resource, training increases use of fatty acid, endurance ability, and oxidation of triglyceride. During high level training, catecholamine secretions and restraint of fatty acid use caused by insulin increases dramatically, this results in reduction of free fat acids and reunification of free fat acids into triglyceride. Training restrains insulin activity and reduces plasma acid density, however, elite athletes have high triglyceride-fatty acid cycle. Although enzyme's activities and mitochondira's density increase after training, it's not certain that enzyme's activities is major factor in restraint of fatty acid oxidation in exercising muscle cells. Stores of fat leads to increases of fat oxidation, performance and reduces use of carbohydrate, however, there is no absolute evidence to support these results.

이정용,이창섭 한국화재소방학회 2003 한국화재소방학회논문지 Vol.17 No.1

가설건축물은 일시적으로 사용될 목적으로 축조되는 건축물이다. 그러나 가설건축물이 건물과 연결되어 장기적으로 사용되는 경우 화재예방상의 위험성이 증가하나 이를 위한 제도적 장치는 마련되어 있지 않다. 본 연구에서는 공장건물과 연결되어 사용되는 가설건축물의 화재를 예방하는 방안을 모색하기 위하여 현행 관련법규 검토하고, 표본지역에 대한 실태조사를 실시하고, 소송사례를 수집하였으며, 가설건축물의 유형별 위험성을 고찰함으로써 다음과 같은 결론을 얻었다. 가설건축물을 본 건물과 이격하여 설치하도록 하는 규정을 건축법 시행령에 신설해야 한다. 그리고 건축법의 규정에 의해 증축이 불가능하여 가설건축물이 설치되는 경우, 건축물과 연결된 가설건축물을 소방법상의 특수장소에 포함시킬 수 있도록 소방법 시행령을 개정해야 하며, 건축물과 연결하여 가설건축물을 설치하는 것을 허가사항으로 하여 허가시 소방관서장의 동의를 구할 수 있도록 건축법을 개정해야 한다. Temporary constructions are defined as constructions for temporary use, but frequently, they are used long like permanent constructions and connected with main constructions. In this case, fire hazardousness increase. But there is no way to control this hazard in our system. This study include investigation of present related law, survey about sample complex, collection of related lawsuit result and estimation of hazardousness of each contemporary construction type. The conclusion is that the article that specify distance between main construction and temporary one should be created in the architectural law. Or to apply fire service law to area of temporary construction, fire service law should be changed properly.

Diet has been convinced to be an influential environmental factor of the development of coronary heart disease (CHD), though it is still on debate. The related dietary components include total fat, saturated fat, cholesterol, animal protein, fiber, and sugar. During last 50 years, most of the dietary studies concerning atherosclerosis and CHD have emphasized the role of fats. In recent years, however, the effect of sucrose on the development of CHD has received considerable attentions. In 1957 a significant positive association of sugar consumption with the coronary mortality was first pointed out by Yudkin in London. Since then, various epidemiologic and experimental studies have been carried out upon their relationships and have suggested the hyperlipidemic effect of sucrose as a possible etiologic factor of CHD In order to learn to what extent dietary sugar influences the development of CHD in man, the evidences were reviewed under three headings. First, interrelations between the intake of sucrose and the CHD incidence: second, experiments in man and in animals: finally, suggested possible metabolic mechanisms.

Staphylococcus lugdunensis (S. lugdunensis) is a newly identified pathogenic species of coagulase negative staphylococci and an occasional but not rare cause of severe infections, such as infective endocarditis after dental extraction, bacteremia, osteomyelitis, peritonitis, and soft tissue infections. As antibiotic use increased, resistance rapidly developed. Some strains have plasmids related to antibiotic resistance. To characterize S. lugdunensis in acute oral infection, S. lugdunensis was isolated from the patients with acute oral abscess, osteomyelitis, and normal persons. Antibiotic resistance, in vitro cellular toxicity, in vivo virulence, δ-like hemolysin activity, and synergistic hemolysis on sheep blood agar plates were investigated. The dot blot analysis and Southern blot analysis of staphylococcal DNA was performed with δ-hemolysin gene probe of Staphylococcus aureus. (S. aureus) Staphylococcal DNA was cloned, nucleotide sequence was analysed, and homology was compared with other sequence in Gene Bank. S. aureus, S. lugdunensis, Staphylococcus cohnii (S. cohnii), and other coagulase negative staphylococci (CNS) were isolated from the patients with acute oral infection. The isolation ratio of S. lugdunensis in the patients with infection was higher than that of healthy persons, but the isolation ratio of S. aureus in the patients with infection was similar to that of healthy persons. S. lugdunensis from the patients with acute oral infection showed the resistance to penicillin, methicillin, cephalothin, and clindamycin. S. lugdunensis in the patients had cellular toxicity in vitro and virulence in vivo. All strains of S. lugdunensis had δ-like hemolysin activity against rabbit erythrocytes. Four of the six strains of S. lugdunensis gave synergistic hemolysis with S. aureus on sheep blood agar plates. In dot blot analysis, all strains of S. lugdunensis showed the positive reaction with the probe of δ-hemolysin gene in S. aureus, but a 7.3 kb HindⅢ fragment was observed in the DNA of S. lugdunensis that gave synergistic hemolysis in a Southern blot analysis. The molecular size of partially purified δ-hemolysin was about 50 kd. The cloned fragments from the chromosomal DNA of S. lugdunensis showed the partial homology with the insulin receptor-related and dopamine receptor of humans. These results suggest that S. lugdunensis might be an important pathogen in acute oral infection and show some homology with eukaryotes.
