식용 및 약용으로 사용되는 갯기름나물의 기내배양을 통한 재분화율을 조사하였다. 캘러스는 잎과 엽병의 절편체에서 발생하였고 0∼5 mg/L의 NAA와 0∼10 mg/L BA가 첨가된 MS 기본배지에 치상하여 암배양 결과 자발적인 배 분화와 기관 분화를 보여주었으며 2.5 mg/L NAA와 10 mg/L BA의 조건에서 재분화율이 가장 높았다. 체세포 배의 발생양상은 구형, 심장형, 어뢰형을 거쳐 자엽 단계로 발달하여 전형적인 접합자 배의 모습으로 발달하였다. 배 발생한 일차 체세포배를 0.2 mg/L의 NAA가 첨가된 배지에서 배양하였을 때, 이차 체세포배가 발생하였으며 주로 일차 체세포배의 배축과 하배축에서 많이 발생하였고 그 다음으로 자엽이나 뿌리 부분에서 발생하였다. Peucedanum japonicum $T_{HUNB}$ used as a edible and medicinal plants was investigated for in uitro regeneration. Callus formation occurred on leaf and stem explant cultures and showed spontaneous embryogenic and organogenic capability on MS basal medium supplemented with 0.1~5 mg/L NAA and 0~10 mg/L BA in dark. The regeneration was highest on the condition supplemented with 2.5 mg/L NAA and 10 mg/L BA. Development of the somatic embryo progressed through the globular, heart-shaped, torpedo-shaped and cotyledonary stage, typical of zygotic embryos. When the first somatic embryos was cultured on the medium supplemented with 0.2 mg/L NAA, secondary somatic embryo were induced with higher frequency on the hypocotyl then on the cotyledon and root.t.

김옥태,김민영,박윤정,홍민희,안준철,오만호,황백,Kim, Ok-Tae,Kim, Min-Young,Park, Yoon-Jung,Hong, Min-Hee,An, Jun-Chul,Oh, Man-Ho,Hwang, Baik 한국식물생명공학회 2002 식물생명공학회지 Vol.29 No.4

기내에서 병풀의 식물체 배양을 확립하였고 기본배지 설정 및 대량원소들, sucrose 농도가 triterpene glycoside (Made-cassoside와 Asiaticoside: M&A) 생산에 대한 영향을 조사하였다. 병풀 식물체가 각각의 배지에서 배양되었을 때, MS와 RCM배지는 각각 식물체 생장과 M&A 생산에 대해 가장 좋은 결과를 나타냈다. 하지만, M&A에 대해 가장 높은 생산성은 B5 배지로 나타내었다. B5 배지의 대량영양소인 KNO$_3$는 25 mM, NaH$_2$PO$_4$는 1 mM, CaC1$_2$는 1 mM 그리고 MgSO$_4$는 1~10 mM에서 M&A 생산이 최적을 이루거나 증가시켰다. Sucrose를 농도별로 처리했을 때, 6% sucrose 농도에서 가장 높은 M&A 생산을 얻을 수 있었다. Whole plant cultures of Centella asiatica (L.) Urban in vitro were established and the effects of basal media, some macro elements and sucrose concentration on productivity of triterpene glycosides (madecassoside and asiaticoside: M$\varepsilon$A) were investigated. Among the media (MS, B5, RCM) tested, MS and 0.5 RCM medium were the best for plant growth and M$\varepsilon$A production, respectively. However, taking into account the M$\varepsilon$A productivity, B5 medium was superior (M$\varepsilon$A: 14.28 mg/g dry wt.). Major macronutrients of B5 medium adjusted with the concentration of 25 mM KNO$_3$,1 mM NaH$_2$PO$_4$, 1 mM CaCl$_2$ and 1~10 mM MgSO$_4$, caused elevated or optimized levels of M$\varepsilon$A. On sucrose concentration, the highest yields of M$\varepsilon$A were obtained from 6% sucrose.

The purpose of this study is to investigate the viewpoint of human body of Hebraism which influenced most largely western culture and western people, using the New and Old Testament, Philo`s work and Talmud and to consider the modern meaning on the viewpoint of human body of Hebraism. According to the New and Old Testament, the Hebraic viewpoint of human body is different from that of Hellenism. The essence of Hebraic viewpoint is monism that means there is no essential difference between body and soul. Philo, a Judaic thinker, gave much more weight body than mind too. He didn`t regard the body as the vulgar thing while Hellenism philosopher regarded human body as the grave or the prison of soul. He said that the body is the home, the sanctuary and the brothers of soul. Talmud said that the body is closely connected with soul, and since the body is the creature of God, we also have to respect the body as equally as the soul. Moreover the commanding body was rated high and was looked upon as those who could receive the God`s recognition. In conclusion, we can analogize that the asceticism of the Dark Ages was the result of misunderstanding of the Hebraic viewpoint of body. Besides the viewpoint of human body of Hebraism exerts an important effect upon the education for the whole man or the character building in the physical education of present-day.

성경에 나타난 체육 -신체관, 스포츠, 여가관을 중심으로-

김옥태 ( Ok Tae Kim ) 기독교학문연구회 2012 신앙과 학문 Vol.17 No.2

이 논문은 신·구약 성경과 관련 문헌을 통하여 신체관, 스포츠, 여가관 등을 중심으로 성경에 나타나 있는 체육의 개념에 대해 고찰한 것으로서 결과는 대체로 다음과 같다. 첫째, 성경에서의 신체관은 피조의 영적 존재이다. 즉 인간은 하나님의 형상과 모양에 따라 창조된 육을 가진 존재이나 영혼도 소유하고 있다. 육체는 약하지만 무시할 것이 아니라 잘 관리할 책임도 있다. 일찍이 성경은 오늘날 체육의 개념인 심신일원론적이었다. 둘째, 성경에 나타난 스포츠는, 구약시대에는 주로 활, 칼, 창, 물매 등 전쟁과 관계있는 것과, 무용, 수영 등이 성행하였다. 신약시대에는 바울서신에 여러 비유로 나타나 있는데, 이로써 스포츠가 부정되지 않고 긍정적으로 평가되고 있다는 것을 알 수 있다. 셋째, 성경에서의 안식일은 인간의 일과 탐욕에 대한 규제와 하나님이 보인 만족이라는 측면에서 여가적인 의미를 찾을 수 있다. 축제는 하나님이 만든 일종의 놀이라 할 수있고, 특히 그리스도인은 예배를 통하여 축하와 기쁨과 자유를 누려야 하는데, 인간의 문화는 그것을 위축시키고 있다. 결국, 체육이 역사적으로 기독교에서 부정된 적이 많았지만, 성경에 나타나 있는 진정한 의미는 긍정적이며 오히려 권장되어야 하는 것으로 나타나 있는 것이다. This paper considered the concept of physical education in the Bible. The three topics presented were the view of the human body, sports and the view of leisure through the Bible. The results are as follows: First, the view of the body in the Bible, is that we are created by God as spiritual beings both in body and soul. Though the body is weak, we must not neglector the body, but we must manage it responsibily. In the Bible, one can identify similar ideas that are practiced in modern physical education, the Bible shares the same view as modern physical education. Second, in the Old Testament days, archery, fencing, spear and sling were all physical activities related to war, while dance and swimming were related to physical education and sports. In the New Testament days many metaphors are written in Pauline letters, it suggests that sports were not denied but were encouraged and venerated. Third, the Sabbath in the Bible encompasses the meaning of leisure, control of the human`s work ethics, greed and God`s satisfaction. Festivals are a sort of play God has made. Christians should enjoy celebrations, joy and freedom through worship, However human culture restricts these celebrations. Ultimately, though physical education has been denied in Christianity historically, the true meaning of physical education in the Bible is positive and encouraging message for all to practice and enjoy physical education.

The significance of leisure in the Sabbath is great. The purpose of this paper was to explore the meaning of leisure in the Sabbath of the Holy Bible and in the Lord`s day(Sunday) by the times. The results of this study by the Old and the New Testaments and related literatures were summarized as follows: First, God`s rest in the Old Testament emphasized the leisure by setting the limit positively to the work and the avarice of human being, and provided us with the model for the rest and leisure of the man. Second, the rest as a commandment of the Old Testament told the rhythm between work and repose, namely, complement of two kinds. Third, Jesus of the New Testament had a good rest with prayer in spite of His tight schedule, and He encouraged His disciples to have their leisure. Fourth, the Sabbath of commandment of the Old Testament was focused on man`s life and dignity by jusus, and gave us the meaning of leisure. Fifth, the concept and the meaning of the Sabbath have been changed in the doctrine and leisure with times since the Bible age through the present age. Sixth, today Sabbatarianism was declined greatly with the age of mass leisure, but, on the other hand keeping the Sabbath was emphasized.

The purpose of this study is to provide data for promoting elders’ welfare by empirically analyzing the effects of elderly people’s experience of recreational sports participation and leisure competence on the satisfaction with quality of life, in order to improve their health and physical strength as well as to help them have mental, social, and emotional stability. One-way ANOVA and multiple regression analysis are applied to the study with 372 people of elderly participants and the results are as follows: First, according to the analysis of difference in the level of satisfaction with quality of life in terms of individual characteristics, there were significant differences in satisfaction depending on wealth and health conditions, not gender. Men had higher satisfaction with quality of life than women. The group with more wealth had higher satisfaction than the group with less wealth. The group with top level of health condition had the highest satisfaction, and then come the group with medium level of health condition and low level of health condition in order. Second, according to the analysis of difference in the level of satisfaction with quality of life in terms of experience of sports participation, there were significant differences in satisfaction depending on sports type, sports career, number of days of participation per week, and number of hours of participation per day. Competition sports type had the highest satisfaction, and then come rhythmic movement type, outdoor sports type, and training sports type in that order. The group with longer period of sports career had higher satisfaction than the group with shorter period of sports career. The group with more days of participation per week had higher satisfaction than the group with less days of participation per week. The group with more hours of participation per day had higher satisfaction than the group with less hours of participation per day. Third, according to the analysis on the effects of leisure competence of elderly participants in recreational sports upon satisfaction with quality of life, all the sub-variables of leisure competence have significant effects on all the sub-variables of satisfaction with quality of life. Consequently, acknowledging the fact that elderly people’s experience of recreational sports participation and their leisure competence contribute to the satisfaction with quality of life, both administrative authorities in charge of elders’ welfare and leisure sports instructors should make their best efforts with positive PR activities in encouraging elderly people to actively participate in recreational sports for their healthy life of later years.
