Oriental Medicine has long been centered around Qi[vital force], hence adopting Qigong and the art of regimen for training the body and relaxing the mind so as to prevent and heal illness. It has not been such a long time since Qigong method had been performed and spot-lighted out of numerous methods in Oriental Medicine. In China and Korea alone, diverse cases and papers are published, only revealing so many steps toward the establishment of diachronic description, theoretical foundation, and clinical practice. Historical approach is an essential part of recognizing a subject. When you step along its path and comprehend what it were, you can also grasp what it is and what it will be. Establishment of Qigong history is also vital to research Qigong in theory and practice. Generally, Qigong was transmitted from China to Korea, whereas the opposite explanation, that it originated from Korean Taoism, is supported by the minority based on certain texts concerning ancient history. In this paper, I support the theory of Korean originality based on the following grounds: First, the location of Qi and Van, the motherland of Chinese Taoism provides a strong evidence that Korean tradition had been absorbed by them and formed the tradition of mystic hermits(shenxian). Second, Guangchengzi, the originator of mystic hermits, is from Dongyi tribe according to Cheonghakjib. Third, the myth of Dangun has pure form of unique Korean folklore possessing the distinctive feature of mystic hermits tradition, uninfluenced by Chinese Taoism. Fourth, in ideographical aspect, the character 'xian(仙)', was invented as the Korean concept of mystic hermits[xian] was flowed in to China. Moreover, There is high probability that it was based on the concept of mystic hermits shown in the myth of Dangun in Its original formation. Fifth, considering the relation between wild ginseng and the tradition of mystic hermits, that tradition can be formed very naturally in Korean area. Sixth, the analogical similarity between archetype of Korean tradition and Taoistic trilogy, the foundational idea of the tradition, gives genealogical basis to its origin. Seventh, the tradition of mystic hermits and Shamanism, which constitues the prototype of Korean mind as an original religious tradition, are undiscernible in their root In Conclusion, We can reach the idea that the origin of Qigong derives from Korean tradition, not that of China. The tradition of mystic hermits was transformed to ego-centric seclusionism when it faced the anarchy of Warring states period in China, whereas it was developed into humane proriety and worship of Heaven base on the programme of 'universal fraternity in pursuit of interst for man'. In prospect, it is highly required to develop and interpret traditional discipline methods in Korea so as to utilize them for clinical Qigong in practice.

Mylabris is the dried body of the chinese blister beetle. The species used in medicine are Mylabris phalerata and M. cichorii. In recent studies, it has been found that Mylabris possesses antitumor properties, increases the number of leukocytes, and has irritant effects on the urinary organs. The crude extracts of Mylabris have been noted for their highly irritant action and other traditional uses of Mylabris include treatment of poor local blood circulation. The active constituent of Mylabris is cantharidin. The chemical is notable for its vesicant properties, but with severe side effects such as nephrotoxicity. This experiment examined the effect of extracts and fractions, obtained from Mylabris phalerata Pall. on hair growth activity of the C57BL/6N mice after topical application to skin. First, we examined the effect of an extracts, obtained from the alcohol extracts of dried Mylabris phalerata Pall. on hair growth activity of the C57BL/6N mice after topical application to skin. Second, we examined on hair growth activity of the cantharidin fraction of Mylabris phalerata Pall. compared to the control and 1% minoxidil groups. Third, we investigated the number of hair follicle and mast cells after topical application of extracts of Mylabris phalerata Pall. to skin for 16 days. The results were as follows: Hair growth effect from the extracts of Mylabris phalerata Pall.(0.312%) was observed in 80% of mice whose hair had been removed in 13 days. Hair growth effect from the extract of Mylabris phalerata Pall.(0.312 and 0.625%) and 1% minoxidil group was observed in 100% of mice whose hair had been clipped in 20 days. Hair growth effect from the cantharidin fraction(0.5%) and water fraction(0.5%) of Mylabris phalerata Pall. was observed in 100% of mice whose hair had been clipped in 24 days. The hair growth effect on the cantharidin fraction(0.125%) was observed to be strong compared with the minoxidil(3%) group, commercial hair growth agents, in mice whose hair had been clipped in 19 days. In the spontaneous alopecia mice model, the hair growth effect from the cantharidin fraction (0.125%) was observed to be strong as compared with the states before the 13 days experiment. These experiments suggest that extracts and fractions of Mylabris phalerata Pall. may stimulate the topical hair growth activity in low doses.

The Recommended Dietary Allowances(RDAs, Nutrient standards), dietary guidelines, and food guides, each define aspects for a healthy diet in different ways. The RDA and food guide for Koreans were first established in 1962 by the Food and Nutrition Committee of the Korea FAO Association. The committee released the RDA and suggested ways to intake the recommended nutrients. Every five years, the committee has added more data and released revisions. The latest edition of the RDA is the 6th revision. In the beginning, the concept of basic food groups was emphasized as basic data for planning means based on RDA. In the 5th revision, the basic food groups and dietary guideline for public health from the Ministry of Health and Welfairs(December, 1990) suggests that, 1) Eat a variety of foods with a recommended fat intake equaling or less than 20% of total calories ; 2) Maintain ideal body weight and prevent obesity ; 3) Eat foods low in salt. Salt intake should not exceed 10g ; 4) Do not drink too much ; 5) Eat regularly and enjoy meals. After these guidelines were established, the first nutritonal education efforts guidelines were developed in 1984. Despite broad possibilities for application, they had limited use, mainly as a nutritional assessment and food balance sheet preparation. They were not well utilized in public nutritional education and nutritonal policy through the media because of the weakness of the government's food and nutriton policy. Also a lack of administrative support and dietitians in the health department and administrative organizations was partly to blame. In regard to public health and nutrition status, life expectancy has increased 10 years since the 70's and the elderly population increased threefold in 1995 compared to 1960. The common causes of death in 1996 by 19 Chapters classification, were first disease of the circulatory system ; the second, neoplasms ; the third, external causes fo mortality ; the forth, diseases of the digestive system ; and the fifth, respiratory system diseases, In food intake, grain and complex starch intake has decreased while fruit and animal foods have considerably increased. Therefore, energy from carbohydrates has decreased while energy from protein and fat has increased. Energy intakes from protein, fat and carbohydrates were respectively 12.5, 7.2 and 80.3% in 1969 but 16.1, 19.1 and 64.8% in 1995. 62.9% of the householes had the fat energy less than 20%, while 37.1% had the fat energy above 20%. The only intakes of vitamin A and calcium were below RDA levles. Therefore, nationwide attention should be focused on public nutriton education and public activities with supplementation of the RDAs, according to the food guide and the dietary guideline.

Objectives: The aims of this study were to review the standards and key components of the standards for disposable masks in Korea, the US, EU, Japan, and China and to evaluate the appropriateness of disposable masks during a virus pandemic. Methods: We reviewed the standards in the above countries and compared their key elements for each standard. For the second purpose, systemic paper gathering using key words like 'mask', 'respirator' 'virus', and 'coronavirus' in the PubMed search engine was performed. Fifty-three papers were selected and reviewed in regard to the appropriateness of test protocols with sodium chloride(NaCl) particles for virus filtration and the effectiveness against viruses. Results: The standards for masks are largely divided into two categories: US standards and EU standards. In Korea, the Ministry of Employment and Labor adapted the EU standards for workers and the Health Masks adopted the Ministry of Employment and Labor standards by the Ministry of Food and Drug Safety. Regarding airborne viral infections, WHO emphasizes only droplet infection, while many studies have shown that small particles enter the air through coughing or sneezing, which increases the possibility of airborne infection. Compared to other particles, various factors such as airborne viability and the ability to replicate the virus in the body are further involved in the virus's airborne infection rate. Airborne infection is classified into absolute air infection, preferential air infection, and opportunistic air infection. The NaCl-certified N95 mask showed good filtration efficiency against viruses and NaCl particles were proved to be a surrogate material for viruses. From this, KF94 is also expected to be effective in blocking viruses. Conclusion: The N95 test method could be used as a surrogate test method for virus filtration. N95-class masks have been found to effectively block viral infections in the air. However, surgical or medical masks are only partially effective against airborne virus infection though they could effectively block large droplet infection. However, most studies considered in this study targeted N95 in foreign countries and studies on masks actually used in Korea are very limited, so studies on microorganisms and reuse on domestic masks should be conducted in the future.

본 연구는 다양한 조건에서 장기 보존한 느티만가닥버섯 균주의 균사 생존력과 재배성능 검증을 수행하였다. 균사 생존력은 장기 보존된 균주를 9, 21, 33, 45개월 단위로 해동하여 PDA 평판배지에 접종한 다음 1, 2, 3, 4, 5차 계대배양에 따른 균사 생장길이를 측정하여 검증하였다. 액체질소에 보존한 균사를 해동 직후 실시한 1차 계대배양에서는 동결보호제로써 Glycerol 10%를 단용으로 처리한 실험구에서 균사생장이 저조한 결과를 나타내었으나, 5차 계대배양에서는 버섯 균사의 생장력이 다른 실험구와 동일한 수준으로 회복되어, 저장방법에 따른 균사의 생존력에는 큰 영향이 없는것으로 판단된다. 그러나 느티만가닥버섯을 액체 질소에 장기간 보존하고자 할 때는 동결보호제로 사용되는 Glycerol 10%에 Trehalose 5%를 첨가하여 보존해야 균사의 생존력을 유지하는데 도움이 된다. 장기 저장에 따른 느티만가닥버섯 균주의 재배 성능 시험에서는 $4^{\circ}C$ 사면배지에 보호제로써 mineral oil을 사용하는 것이 사면배지 자체로 보존하는 것에 비해 수확량이 감소하는 결과를 나타내므로 장기 저장시에 mineral oil을 사용하는 것은 지양해야 할 것으로 판단된다.

The adequate intake of energy and lysine for primiparous sows are necessary for maternal growth of sows and growth of their progeny. This study was conducted to evaluate the effects of dietary energy and lysine levels on primiparous sows and their progeny. A total of 48 gilts (Yorkshire × Landrace), with an initial body weight (BW) of 168.1 ± 9.71 kg and at day 35 of gestation, were allotted to eight treatment groups with a 2 × 4 factorial arrangement. The first factor was metabolizable energy levels in diet (3,265 or 3,365 kcal of ME/kg), and the second factor was lysine levels in diet (gestation 0.55%, 0.65%, 0.75%, 0.85%, lactation 0.70%, 0.85%, 1.00%, 1.15%). The BW gain (p = 0.07) and backfat thickness (p = 0.09) in the gestation period showed a tendency to be increased in sows fed the high-energy diets. In the lactation period, sows fed the high-energy diets tended to be greater BW (p = 0.09) and less BW loss (p = 0.05) than those of sows fed the low-energy diets. Sows fed high-energy diets had a tendency of greater piglet weight at day 21 of lactation and greater piglet weight gain (p = 0.08 and p = 0.08, respectively). Although the blood urea nitrogen (BUN) was increased linearly as dietary lysine level increased at day 110 of gestation (Linear, p = 0.03), the BUN was decreased linearly as dietary lysine level increase at day 21 of lactation (Linear, p < 0.01). In the composition of colostrum, sows fed high-energy diets had greater casein, protein, total solid, solid not fat, and free fatty acid concentrations than those of sows fed low-energy diets (p < 0.05). Supplementation of total lysine 0.75% for gestation and 1.00% for lactation with 3,365 kcal of ME/kg energy level could be applied to the primiparous sows' diet to improve performance of sows and growth of their progeny.
