This study was conducted to investigate the effects of aerobic capacity on blood lactate changes after supramaximal progressive loaded exercise. The subjects were divided into Handball players(HB, n=6)group and Control(CT, n=6)group. All subjects exercised according to the protocol by bicycle erogometer. Blood lactate concentration was also measured during the test time. The RER values of CT group were relatively higher than that of HB group. In particular, the RER values of HR group at exercise 8 & 12min were significantly lower than that of CT group(P<0.05). The blood lactate concentration of HB group was significantly lower than that of CT group at 12min during the exercise(P<0.05). During the recovery times the blood lactate concentration of HB group were significantly lower than that of CT group. In addition, blood lactate clearance of HB group was also higher than that of CT group during the recovery time. From these results, it was suggested that lactate clearance during the supramaximal exercise may be affected by the level of endurance exercise performance.

피부미용을 위한 아로마테라피(Aromatherapy)의 작용원리 및 활용방법

송선영,김춘일 제주한라대학 1999 論文集 Vol.23 No.-

Aromatherapy is a treatment which recovers the balance of mind and body. This is an application to human body, using aroma oil, that is, volatile oil contained in roots, fowers, leaves, stems, shells and seeds of special herbs and cells of fruits, etc. Aroma oil promotes immunocompetence, has an effect on all internal organs, glands and functions of hormones and heightens resistance to mold. And also it stimulates the nerves and rests our mind by intensifying or relaxing muscles, so it helps remove slight symptoms of everylife rather than severe diseases. This treatise shows you the usage and principles of aromatherapy good for beautiful skin. It counteracts poisonous characters of a body through bathing, foot-bathing, spreading, drinking, inhaling, massage and wet-compressing, promotes to renew cells and then cures and improves the quality of the skin. And also the fragrance of aroma oil stimulates the central nerve linked with the sense of the smell and stabilizes the balanced state of the mind. That has a good effect on mental improvement and stress management. This aromatherapy has been known good for beautiful skin and used in massage salons for 2 to 3 years. New aromatherapy is reported on its effects and approved in medical science as enough as doctors and herb doctors make the institute authorized. Aromatherapy is accessible to causes of diseases not to be seen which are coming from irregular living habits throughout long times and normalizes and improves functions of skin. So I hope the aromatherapy becomes stable and practical skin management and popularized so as to be vital tonics and living science as well as alternative medical science.

아로마 요법(Aromatherapy)을 이용한 비만관리

김춘일,송선영 제주한라대학 2000 論文集 Vol.24 No.-

Obesity, a state of excessively accumulated fat inside the body, has frequently been generated due to the imbalance between the intaking calory and the consuming calory which was caused by the increase of intaking high-calory foods and at the same time by the decrease of people's physical activities in our convenient modern lives. In America's case, a third of American people are obese and obesity has become one of major health problems. Even in our country, as our way of eating habits are getting westernized and our way of life is getting convenient, obesity is gradually in the increase and can especially cause serious geriatric diseases. Accordingly various ways of losing weight such as alimentotheraphy, exercise theraphy, medicinal theraphy, operation theraphy, and aromatheraphy have been introduced and sometimes executed without any filtering. This can not only hurt people's health but also cause serious social problems, lowering the work efficiency and reducing the productivity. Most people, however, have an inclination to a faster and simplier way of losing weight. Especially the fact that the aromatheraphy gives powerful and positive influences both to the mind and the body, is favorably received among people all around the world including Japan, Australia, and some American countries. And it has been regarded as a practical and safe beauty theraphy these modern days when many people are interested in natural ways of keeping health. Lots of diet products based on this aromatheraphy have been recently introduced in our country. In this respect, a research & analysis of the aromatheraphy which uses Pachouli of suppressing the appetite centural nerve and Juniper, Geranium, Eucalyptus of showing excellency in urinating and in dissolving fat, is essentially required. On this, I wanted to analyze the effect of aromatheraphy in obesity control and went into a clinical research using aroma oil as a single theraphy. In spite of the only six-week clinical demonstrations, I could get the result of 4.8㎏ loss in weight and of 3.1% reduction in body fat. As you can see in the above result, aromatheraphy could reduce body fat as a single theraphy, but experimental researches and variously repeated studies should be continued to confirm its popularization by embodying its functions in reducing body fat and by securing concrete and relative evidences, I think.

키에르케고어의 역설과 비트겐슈타인의 '새장'에 관한 고찰 : 키에르케고어의 사회성을 중심으로 with the problems concerning Kierkegaard's sociality in the center

최춘영,송은재 군산대학교 현대이념연구소 1996 現代理念硏究 Vol.11 No.-

Kierkegaard has been criticized by many commentators on account of being a thinker lacking sociality. That is to say, they think one couldn't find out the concern for society in which we live or social consciousness in Kierkegaard's thought. But is such a criticism undoubtedly right? This treatise is conceived to doubt this criticism in such a way that it could compare Kierkegaard's methodology with Wittgenstein's.

For the comparison of the accuracy of ultimate bearing capacity equations, Terzaghi's, Meyerhof's and Hansen's equation are analyzed by Advanced First Order Second Moment(AFOSM) method. The relationships are investigated between the probability of failure and the central factor of safety. Some conclusions obtained in this study are presented as follows; 1) As a result of reliability analysis considering correction factors, it is found that Hansen's equation is more accurate than the other equations. 2) Because Terzaghi's equation underestimates the bearing capacity, it gives lower values of probability of failure than those by the other equations. 3) For a given value of the coefficient of variation the probability of failure is more sensitive to the internal friction angle in comparison with other factors such as the cohesion and load.

1급 와동에서 상아질과 복합레진의 결합강도에 대한 중합방법의 효과

백신영,조영곤,송병춘 大韓齒科保存學會 2008 Restorative Dentistry & Endodontics Vol.33 No.5

본 연구는 1급 복합레진 수복물에서 할로겐 광조사기를 이용한 4가지 중합방법이 상아질의 결합강도에 미치는 효과를 알아보기 위하여 시행하였다. 발거된 상·하악 대구치 20개의 교합면측 법랑질을 Diamond Wheel Saw를 이용하여 제거한 후 1급 와동을 형성하였다. 중합방법에 따라 파동지연 중합방법 (PD) 군,연성 중합방법 (SS) 군,파동 중합방법 (PC) 군,지속 중합방법 (CC) 군의 4개 군으로 분류하고, Z250 복합레진을 각 군의 와동에 충전한 후 광조사하였다. 각 군의 시편을 주수하에 접착계면의 단면적이 1㎟가 되도록 절단하여 막대모양의 시편을 제작하였고,각 군당 20 개의 시편을 사용하여 미세인장 결합강도를 측정하여 다음과 같은 결과를 얻었다. 1. PD 군은 PC 군과 CC 군보다 통계학적으로 더 높은 미세인장 결합강도를 나타내었다. 2. SS 군의 미세인장 결합강도는 PC 군과 CC 군보다 높게 나타났으나,통계학적으로 유의한 차이를 나타내지 않았다. 결론적으로,1급 복합레진 수복물을 중합할 때 파동지연 중합방법과 연성 중합방법을 사용하여 중합속도를 조절함으로써 상아질과 복합레진의 결합강도를 개선할 수 있을 것으로 사료된다. The purpose of this study was to compare the micro tensile bond strength in Class I cavities associated with different light curing modes of same light energy density. Occlusal enamel was removed to expose a flat dentin surface and twenty box-shaped Class I cavities were prepared in dentin. Single Bond (3M Dental product) was applied and Z 250 was inserted using bulk technique. The composite was light-cured using one of four techniques; pulse delay (PD group), soft-start (SS group),pulse cure (PC group) and standard continuous cure (CC group). The light-curing unit capable of adjusting time and intensity (VIP,Bisco Dental product) was selected and the light energy density for all curing modes was fixed at 16 J/㎠. After storage for 24 hours,specimens were sectioned into beams with a rectangular cross-sectional area of approximately 1 ㎟. Microtensile bond strength (μTBS) test was performed using a universal testing machine (EZ Test,Shimadzu Co.). The results were analyzed using one way ANOVA and Tukey's test at significance level 0.05. The μTBS of PD group and SS group was higher than that of PC group and CC group. Within the limitations of this in vitro study,modification of curing modes such as pulse delay and soft start polymerization can improve resin/dentin bond strength in Class I cavities by controlling -polymerization velocity of composite resin.
