류록규,문태영 三陟大學校 2001 論文集 Vol.34 No.3
The purpose of this study was to define the relationship between roller skate player's athletic capabilities, events and lower limb length, by making a comparative analysis of the ratio of lower limb length to physical height and the ratio of lower leg length to lower limb length by gender, school grade and event between excellent roller skate players and non-excellent roller skate players, and between long-distance roller stake players and short-distance roller skate players. It's additionally intended to find out whether or not the ratio of lower limb length to physical height and the ratio of lower leg length to lower limb length contributed to judging athletic capabilities and the type of events. The findings of this study were as follows. First, for the excellent roller skate players, the long-distance players in the boy's high school had longer lower limb compared to physical height than the short-distance players in the same high school, but the two groups were not different in the ratio of lower leg length to lower limb length from each other. There was no difference in both the ratio of lower limb length to physical height and the ratio of lower leg length to lower limb length between the long- and short-distance players in the boy's and girl's middle schools and the girl's high school. Second, for the non-excellent roller skate players, the long-distance players in the boy's middle school possessed longer limb compared to physical height than short-distance players in the same school, but the two groups were not different in the ratio of lower leg length to lower limb length. There was no difference in the ratio of lower limb length to physical height and the ratio of lower leg length to lower limb length between the short- and long-distance players in the girl's middle school and the girl's and boy's high schools. Third, in case of the long-distance roller skate players, there was no difference in the ratio of lower limb length to physical height and the ratio of lower leg length to lower limb length between the excellent and non-excellent players in all the boy's and girl's middle and high schools. Fourth, in case of the non-excellent roller skate players in the boy's middle school, the factor that had an impact on discriminating the long-distance players from the short-distance ones was the ratio of lower limb length to physical height. On the contrary, both the ratio of lower limb length to physical height and the ratio of lower leg length to lower limb length didn't exert an influence on discriminating the type of events for the non-excellent roller skate players in the girl's middle school and the boy's and girl's high schools

전록원,허경회,이원진,허민석,이삼선,최순철 대한구강악안면방사선학회 2009 Imaging Science in Dentistry Vol.39 No.2
Purpose : To investigate the incidence and prevalence of C-shaped root canal using computed tomographic images of head and neck in Korean population. Materials and Methods : Regardless of each examination purpose, randomly selected 268 examples which have serial axial computed tomographic images with 8 normal molars in maxilla and mandible were selected and investigated. Defined C-shaped root canal and we could get 82 proper image examples in view of this definition. These were detected and investigated of incidence and prevalence of C-shaped root canal. Results : C-shaped root canals were found in 82 examples among 268 (30.6%) and 147 teeth. They were only found on molar area, and the highest incidence was 37.41% of left mandibular second molars, and the lowest was 2.04%of right maxillary second molars. On prevalence of tooth position, mandibular second molar was the highest, 65% of C-shaped root canal teeth and maxillary second molar was 6% the lowest. Conclusion : 31% of randomly selected CT images no considering check-up reason have C-shaped root canals. The C-shaped root canals of mandibular second molar are found most frequently and they are also detectable on maxilla. On Korean population, C-shaped root canals are one of conditions that have to concern with dental treatment for it appears at a high prevalence relatively.

환경호르몬 : 무엇이 문제이고 어떻게 연구할 것인가? What is the Issue and Future Research Directions
김록호 한양대학교 의과대학 1999 한양의대 학술지 Vol.19 No.2
It is still at the hypothesis-formulation stage that endocrine disruptors affect human health. The decline of semen quality, the increase in the urological birth defects and the cancers in the reproductive organs such as breast and prostate are a few examples that were suspected to be associated with the exposure to endocrine disruptors. These health effects were shown to occur by the exposure to the endocrine disruptors in the experimental studies using animals or cultured cells. However, epidemiological evidence is still missing on the notion that these trends are directly associated with the exposure to the endocrine disruptors. To fill the gap between the hypotheses and the evidence, there should be a large-scale, long-term, multidisciplinary, cohort studies to examine the health outcomes and exposure in the human population. South Korean government recently decided to fund epidemiological research on these issues. In the early half of the 21st century, researchers might be able to answer to the question whether arguments surrounding the global health effects of the endocrine disruptors are a fact or a myth.

The statistics shows that more than 80% of the adults experienced lumbago at least one time in their in their life, and insufficient exercise and other reason result in the serious lumbago occurrence. In order to solve this serious problem, the following data based on the precedent studies shows how to prevent and alleviate lumbago 1. The prior way of lumbago prevention is how to avoid acute traumas. It is also important not only to prevent the weakness of the muscular power and stiffness but also to be careful not to have a complication after rest cure of lumbago. 2. A fine posture prevents lumbago. It is a way of cure and prevention against lumbago. The first step of lumbago prevenaion is to take the fine posture. 3. Make it a rule to walk. The muscular group supporting the backbone is moving rationally when people walk. Walking helps the blood to circulate and gives vitality to the muscle by removing fatigue stuff quickly. 4. Not to sit in the same posture for a long time. When a man sits, the lower part of lumbar is loaded about 60% of weight and pushes the lumbar disk. In result, an abdominal muscle become shrived and muscular movement declined. 5. Avoid the exceeding exercise forcing the waist. Avarice and thoughtless action have a serious influence on the muscle and ligament. Especially a half-stand half-sit posture is dangerous. 6. Be sure to warm up before and after exercise. Today many people are eager for sports, and the case of hurting the waist is increasing owing to the exercise. It is important to consider one's age and ability in starting exercise. 7. Obesity, the enemy of lumbago, must be dissolved. Corpulence may lead to all kinds of illness and lumbago, It is the needless accumulation of the fat in the adipose tissue and the various organ. There is no way of removing corpilence but to exercise continually and to lessen intake with a strong will. 8. Reconginze the necessity of balanced caloric intake. nutrition that is an organism is to make a new tissue or to supplement the physical constituent and to supply the energy of life. Especially adult needs Calcuium 0.6g and Chalybeate 10mg a day. Balancd meal is necessary for the prevention of lumbago. 9. Exercise is effetive to all of the mean. It has to play a role as reinforcing weak parts related to one's special condition. some exercise may worsen existing pain parts. Through the atony exercise of the whole body of muscle, ligament and sinew(an atonic exercise of the whole body), we have to keep strengthening the muscle which suppirts the backbone and abdomen.

Skin whitening products are commercially available for cosmetic purposes in order to obtain a lighter skin appearance. They are also utilized for clinical treatment of pigmentary disorders such as melasma or postinflammatory hyperpigmentation. Whitening agents act at diverse levels of melanin synthesis in the skin. Many of them are known as competitive inhibitors of tyrosinase, the key enzyme in melanogenesis. Others inhibit the transformation of this activated enzyme or the transport of melanosomes from melanocytes to surrounding keratinocytes. To avoid systemic absorption, whitening agent is need to create optimal formulation such as liposome, microemulsion, solid lipid nanoparticles (SLN) and NLC (Nanostructure liquid crystal) as well as patch. Functional ingredients and innovative delivery systems are driving the new product development in the field of cosmetics. In this review we present an overview of whitening products that may decrease skin pigmentation by their interference with the pigmentary processes and may formulate cosmetic delivery systems possessing potential as smarter carrier systems.
