The purpose of this research is to find out if it is possible to apply the Waldorf School's mathematics education method to Korean alternative schools which are run under the national curriculum. To achieve this, the researcher conducted class on geometry for three weeks with ten 7th graders(four girls and six boys) from Apple Tree Waldorf alternative school in Busan, which has adopted Valdorf education courses. For the first two weeks, the class was about 'fundamental geometrical construction', and then it was evaluated. On the third week, the lesson was on plane figures, followed by a test with 9 plane figure questions that are based on general middle school mathematics curriculum. The result shows that most of the students understood 'fundamental geometrical construction'. When it comes to the test on 'plane figures', seven students got 8 out of 9 right, two students got 6 out of 9 right, and one of them had difficulty solving the questions. According to the results of this research, it is thought that there will be no problem for students to understand mathematical concept even if the Waldorf School's mathematics education method is applied to Korean alternative schools. Also, the Waldorf School's mathematics education method is considered to be a good teaching model for the Korean mathematics curriculum which places emphasis on 'mathematical creativity' in regard to the curriculum and contents.

This research is the hair damage as treating a permanent wave before and after that is compared and analyzed the change of physical and mechanical properties. This is the survey of women's hair in 20 years old. On the basis of this we would like to analyze a extend of hair damage. Also, we would to show a basic data for hair damage prevention and hair improvement to keep the beautiful and healthy hair. The conclusion is as follow. : The swelling degree after the treatment was found to be greater than before permanent wave treatment. For the formational characteristics wave, untreated hair certainly had more elastic S curl wave than damaged hair in all the permanent wave treatments, and damaged hair and extremely damaged hair had less elasticity and had saggy S curl wave. The protein permanent and soft permanent wave had thicker, gorgeous, and better elastic wave than the regular permanent wave and direct heating permanent wave in all the hair condition. As the degree of damage on hair got greater, the tensile strength dramatically decreased and as the degree of damage got greater, the elongation was great as well. For treatment method, direct heating permanent wave showed the greatest effect, causing the most damage.

The purpose of this study is to elucidate how walking speed influences on change of angles of lower extremity and ground reaction force in normal and obese people. One group with normal body weight who were experimented at a standard speed of 1.5m/s and the other obese group were experimented at two different walking speeds (standard speed of 1.5m/s and self-selected speed of 1.3m/s). We calculated angles of lower extremity and ground reaction force during stance phase through video recording and platform force measuring. When the obese group walked at the standard speed, dorsi-flexion angle of ankle got bigger and plantar-flexion angle of ankle got smaller, which were not statistically significant. There was no significant difference of knee joint angles between normal and obese group at the same speed walking but significant post hoc only for the first flexion of knee joint in obese group. $F_z1$ was bigger than $F_z3$ in vertical axis for ground reaction force in both groups at the standard speed walking and the same force value at self-selected speed in obese group. $F_y3$ was always bigger than $F_y1$ in anterior-posterior axis in both groups.

This was a follow-up study to the 'Study on the Body Types of Chinese Adult Women I,' which looked into the body types and classified them into representative body type groups, with the subjects of the women residing in Beijing and Shanghai, and it intends to compare the features of the body types by the residential area of each age range. The results were as follows: 1. The measurements physical items of the women residing in Beijing and Shanghai were compared by the age range, and differences were found in all age ranges. In particular, as the age ranges got higher, the differences in the physical measurements were significant. 2. The comparison of the factor score for the women residing in Beijing and Shanghai by the age range indicated the differences in all the age ranges, and the differences were larger as the age got higher. 3. The comparison of the type distribution for the women residing in Beijing and Shanghai by the age range indicated the differences in their 30's and 40's, while any differences in the type distribution were not found in their 20's.

In order to characterize the chemical change, of the constituents and pharmacological transformation of Glycyrrhizae Radix(GR) which may occur during its processing, processed GR has been investigated in comparison with unprocessed GR. It was found that glycyrrhizin(GL) and other several constituents contained in GR were remarkably changed by processing, and the decrease of contents of GL was identified by making use of thin layer chromatography-chromatoscanner. And also, it was found that glycyrrhetic acid (GA) was identified from processed GR. We recognized that commonly processed GR showed less hemolytic effect than unprocessed GR and processed GR at $190{\circ}c$. It was also found that commonly processed GR showed more effective analgesic effect and prolonged the duration of hypnosis induced by pentobarbital-Na in mice as compared with corresponding unprocessed GR and processed GR at $190{\circ}c$. And then, commonly processed GR significantly suppressed the increases of s-GOT, s-GPT and s-LDH activities in injured mice induced by $CCl_4$.

Changes in serum glutamic oxaloacetic transaminase (s-GOT) activities, serum alkaline phosphatase activities and serum total protein amounts were investigated on seven Korean native cows having normal estrus cycle of 18~24 days after normal parturition, dividing estrus cycle into estrus (0~1 days), metestrus (2~6 days), diestrus (7~16 days), proestrus (17~20 days). The results were as follows. 1. Serum GOT activities at estrus ranged from 73.5 to 121.5 Ku with a mean of $89.14{\pm}17.16$ Ku, at metestrus 57 to 89 Ku with a mean of $67.01{\pm}10.81$ Ku, at diestrus 54 to 89.5 Ku with a mean of $67.05{\pm}10.05$ Ku and at proestrus 53 to 112 Ku with a mean of $73.00{\pm}20.05$ Ku. The activities were significantly increased at the estrus comparing with other stages (P<0.01). 2. Serum ALP activities at estrus ranged from 8.0 to 10.4 K-Au with a mean of $8.74{\pm}0.83$ K-Au, at metestrus 6.5 to 9.2 K-Au with a mean of$7.74{\pm}0.76$ K-Au, at diestrus 5.6 to 9.0 K-Au with a mean of $7.67{\pm}1.13$ K-Au, at proestrus 6.2 to 9.3 K-Au with a mean of $7.12{\pm}1.18$ K-Au. The significance was not recognized among the stages of estrus cycle. 3. Serum total protein amounts at estrus ranged from 6.45 to 8.0g/10dl with a mean of $7.25{\pm}0.57/100dl$, at metestrus, 6.37 to 7.9g/100dl with a mean of $7.65{\pm}0.50g/100dl$, fat diestrus, 6.56 to 8.67g/100dl, with a mean of $7.53{\pm}0.55g/100dl$ and at proestrus 5.94 to 7.71g/100dl with a mean of $6.54{\pm}0.65g/dl$. There was not significance among the stages of estrus cycle.

본 연구에서는 한방에서 약용으로 사용하고 있는 미나리 재비과에 속하는 다년생 초본으로 백작약의 열수 추출물을 이용하여 LPS로 유발된 급성 간독성에서의 간 보호효과를 나타내는지 살펴보고자 하였다. 간독성이 유발된 쥐의 혈청에서의 GOT, GPT 그리고 LDH의 감소는 백작약 추출물이 간독성으로부터 간을 보호하였음을 보여주며, 간조직에서의 MDA 감소 및 SOD, CAT, GPx의 활성도 증가 역시 백작약 추출물이 간독성으로부터 간의 기능이 회복됨을 볼 수 있었다. 이러한 결과는 백작약 추출물이 LPS로 유발된 급성 간손상에 대한 보호물질로서의 가능성을 확인할 수 있었다.

귀뚜라미의 곤충산업의 발달로 대량체계화 사육된 귀뚜라미의 새로운 용도 개발의 일환으로 귀뚜라미의 간보호 효과를 조사하였다. 사염화탄소로 6주령의 ICR 응성 생쥐에 급성간염을 유발시킨 후 귀뚜라미 물 추출물(20 mg/kg) 및 메탄올 추출물(20 mg/kg)을 각각 투여하여 GOT, GPT, LDH 간혈청 효소 활성을 조사한 결과 귀뚜라미 메탄올 추출물은 대조구에 비해 GOT, GPT, LDH치가 74, 50, 101% 감소하였다. 지질과산화 억제정도는 귀뚜라미 물추출물 및 메탄올추출물이 정상군 대비 40%이상의 억제 효과를 나타내었다. 또한 강제수영법에 의한 귀뚜라미 추출물의 항피로 효과를 측정시 대조군에 비해 메탄올 200 mg/kg에서 현저한 수영시간 증가를 보여 양성대조군인 토코페롤 100 mg/kg 수준의 유의성 있는 항피로 효과를 나타낸 것을 알 수 있었다. 이상의 결과로 보아 귀뚜라미의 수용성 및 알콜추출물은 간보호 효과를 가지는 건강보조식품으로서 개발 가능성을 가짐을 알 수 있다.
