Zhang Zi-He is one of the Jin&Yuan's four masters, and he used Dong-Xia method well, as well as he is one a medical man who contributed to the development of the medicine. He valued the pathogen. He recognized that the pathogen is a great cause of an attack of a disease, so, first, we have to get rid of pathogen, and it makes the Vital essence and energy recovered. He said, we have to get rid of the pathogen thouroughly. He used 'Wei Ci'-using fei zhen and densely puntuating many times and bleeding much, so the pathogen can't remain. He said if we bleed, it is same as the sweating. And about ${\ulcorner}Nei Jing{\lrcorner}$'s meaning, he said that bleeding is same as sweating and after bleeding, diaphoresis is not required, but it is good to bleed after sweating. He said that we removeing the fire and we can circulate Qi and blood. He set count on the body's circulation of our body, and it is the great cause of a disease. So, He quoted the ${\ulcorner}Nei Jing{\lrcorner}$'s sayings, and emphasized the importane of the circulation of qi and blood. And this Zhang Zi-He's way is in relation with 'Liu He Jian's fire and heat theory.

Immediately after liberation, Shin Kwang-ryul served as the director of the Shinbukcheong People's General Hospital, and defected to South Korea alone in December 1945 with hostility to the Soviet military government. Later, he joined the political operation team (政治工作隊) and was dispatched to the Sinbuk Office as a member of Hamgyeong-do's committee. However, after this was revealed, his wife was taken to the security and tortured to death. Later, when he learned about this, he left a Wolnam Yuseo (越南遺書) and decided to commit suicide. He left politics and started a new family while running a pharmacy. In 1950, he fled Dangjin, Chungnam, during the Korean War and opened an East Asian medical clinic. In 1955, he passed the Korean Medical Examination and opened Cheongpa Oriental Medicine Clinic in Asan, Chungcheongnam-do. In 1969, he ran an East Asian medical clinic in Dohwa-dong, Mapo, Seoul, and moved to Hongeun-dong in 1972 to open Hamnam Oriental Clinic. At this time he wrote a Cheongpa Pharmacy Summary (靑坡驗方要訣). In his later years, he treated poor patients for free, and he continued to work even though he was unwell due to a broken spine. He died in 1980 leaving behind a "proud mind".

Muberry (Morus alba L.) leaves fermented with Hericium erinaceum mycelium (MA-HE) were assessed for the protection against oxidative modification of antioxidant enzymes, Cu,Zn-superoxide dismutase(SOD) and ceruloplasmin(CP). MA-HE were shown to significantly inhibited oxidative modifications and inactivations of Cu,Zn-SOD and CP induced by peroxyl radical. Antioxidant activity of MA-HE evaluated using peroxyl radical scavenging assays. MA-HE showed 44.03% of peroxyl radical scavenging activity at $100{\mu}g/mL$. Thus, MA-HE protect the antioxidant enzymes from oxidative damage by the scavenging peroxyl radicals. The results suggested that MA-HE was effectively removed reactive oxygen species in cells, thereby protecting cytotoxicity caused by oxidative stress.

The (U-Th)/He dating utilizes the production of alpha particles ($^4He$ atoms) during natural radioactive decays of $^{238}U$, $^{235}U$ and $^{232}Th$. (U-Th)/He age can be determined from the abundances of the parent nuclides $^{238}U$, $^{235}U$ and $^{232}Th$ and the radiogenic $^4He$. Because helium is one of the noble gases (non-reactive) with a relatively small radius, it diffuses rapidly in many geological materials, even at low temperatures. Therefore, ingrowth of $^4He$ during radioactive decay competes with diffusive loss at elevated temperatures during the geologic time scale, determining the amount of $^4He$ existing today in natural samples. For example, He diffusion in apatite is known to be very rapid compared to that in most other minerals, causing a significant diffusive loss at ${\sim}80^{\circ}C$ or higher. At ${\sim}40^{\circ}C$, He diffusion in apatite becomes slow enough to preserve most $^4He$ in the sample. Thus, an apatite's (U-Th)/He age represents the timing when the sample passed through the temperature range of $80-40^{\circ}C$. The crustal depth corresponding to this temperature range is called a "partial retention zone." Normal closure temperatures for a typical grain size and cooling rate are ${\sim}60-70^{\circ}C$ for apatite and ${\sim}200^{\circ}C$ for zircon and titanite. Because the apatite He closure temperature is lower than that of most other thermochronometers, it can provide critical constraints on relatively recent or shallow-crustal exhumation histories.

PHWR achieves high neutron economy by adopting heavy water as its moderator and coolant. On the other hand it permits much tritium generation, compared to LWR, due to the neutron capture reaction of deuterium in heavy water. Meanwhile in the reactor core, $^3He formed as the result of-decay of tritium, captures a thermal neutron and transforms to tritium again. The existing calculation models on tritium generation in PHWR neglect the contribution of $^3He$ in both moderator and coolant due to its relatively low solubility. However the neutron capture cross-section of $^3He$ is almost $1.6{\times}10^7$ times as large as that of deuterium. That means that the dissolved amount of 0.03 ppm of $^3He$ in heavy water is enough to generate the same amount of tritium as that generated by the deuterium of total heavy water in the system. This study dealt with the contribution of $^3He$ to tritium generation. As a sample case, the contribution of $^3He$ to the tritium generation in Wolsong #1 was evaluated and compared to the measured values. According to the result of this study, it is concluded that $^3He$ in coolant contributes very much to the tritium generation but that in moderator shows negligible effects due to the low solubility and $^4He$ cover gas. At the beginning of the plant operation, the contribution of $^3He$ is slightly greater than the measured value but agrees well with the measured as the operating time increases.

A purpose of this study is to provide Rousseau's health theory and health education in 『Emil』. Though Rousseau was not so much a doctor as a philosopher, he was good at health care and health education. After he had thought over healthy children for 20 years, he had written 『Emil』 for 3 years. His health theory was included in the book. He was aware of the importance of mother's milk, clothes, and physical health. Especially, he told mothers to rear a child at the breast. He understood thoroughly the demerits of medicines, and made no account of doctors and medicines. But on the other hand, He emphasized natural healing power in human body. He thought that one oneself was a physician. He thought highly of inner healing. He thought that only hygiene of medicine was useful to mankind. He prescribed that hygiene was a kind of ethics education. Therefore, his hygiene was associated with mental health and moral evaluation. Because many years have passed, today we can not accept all his assertions. But we need to stress preventive medicines, spontaneous healing, and self-care in health education.

The specific objectives of the study were (1) to determine the preferences for three home economics curriculum designs(HECD) categorized by Majorie Brown(Technical HECD, Self Actualization HECD, and Practical Reasoning HECD), (2) to determine the differences between middle school HE teachers and high school HE teachers on each curriculum element, and (3) to determine the relationships between preferences for three HECD by curriculum elements and personal and professional characteristics of HE teachers. For these objectives, the subjects were randomly selected from HE teachers of secondary schools in the areas of Seoul, In-Cho, and Keungi. The 300 data collected by mailed survey were analyzed into frequency, percentage, Chi-square, and contingency coefficient using SAS program. The major findings were as follows: 1) the majority of HE teacher respeondents preferred the Practical Reasoning HECD about the following curriculum elements: Purpose of HE education, knowledge, subject matter, teaching method, society and culture, learner, learning atmosphere, and HE teacher's role. 2) No significant difference emerged when Chi-square was applied to determine difference between the two groups(middle and high school HE teachers) on three HECD according to each curriculum element. 3) The contingency coefficient between preferences of HE education purpose for three curriculum designs and age was 21, years of teaching was 23, between preferences of learning atmosphere of three curriculum designs and location of school was. 17. These mean that the younger and more beginning teachers perferred HE purpose of the Practical Reasoning HECD, and HE teachers working in urban area more preferred learning atmosphere of Practical Reasoning HECD.

본 연구는 mushroom complete medium(MCM) 액체배지에 수삼 추출물(GE, $65^{\circ}Bx$)을 첨가하여 면역활성이 증진된 노루궁뎅이버섯(Hericium erinaceum) 균사체를 배양하고, 균사체로부터 활성다당성분을 분획하고자 하였다. MCM에 대하여 GE를 5, 10과 15%(v/v) 첨가한 액체배지에서 균사체를 배양하고, 각각의 조다당획분(HE-GE-5-CP, HE-GE-10-CP와 HE-GE-15-CP)으로 분획하여 면역활성을 측정한 결과, HE-GE-10-CP는 HE-GE-5-CP와 HE-GE-15-CP보다 높은 활성을 나타내었으며, GE를 첨가하지 않은 MCM에서 배양된 균사체 조다당획분(HE-CP)보다 유의적으로 증진된 면역활성을 나타내었다. 또한, HE-GE-10-CP의 DEAE-Sepharose CL-6B 분획물 중 가장 높은 활성을 나타낸 HE-GE-10-CP-II획분은 대조군인 HE-CP의 어떠한 획분보다도 유의적으로 높은 면역활성과 암 전이 억제활성을 나타내었다. 한편, 활성획분인 HE-GE-10-CP-II는 arabinose, rhamnose, galactose, glucose와 uronic acid(molar ratio; 0.34:0.26:0.99:1.00:0.39)로 구성되어 있으나, 대조군인 HE-CP의 동일용매 용출획분으로서 HE-GE-10-CP-II보다는 활성이 낮은 HE-CP-II는 fucose, mannose, galactose와 glucose(molar ratio; 0.32:0.55:1.00:0.96)를 함유하여 다른 구성당 분포를 나타내었다. 따라서 노루궁뎅이버섯 균사체 액체배양에서 수삼 추출물 첨가는 균사체의 구성당 변화를 통한 면역활성 증진에 관여하는 것으로 사료되어 기능성 소재 개발에 유용할 것으로 사료된다.
