Cooking practice is keenly related to not only the betterment of family health but to the improvement of dietary life. Cooking is a kind of practical skill and one is skill in it by repeated practice. The aim of cooking practice in school is to fix cooking method practically and scientifically, to acquire cooking skill. To achieve this aim there are many unrecognized or unsolved problems in the first-line schools. The problems and efficient ways of cooking practice in the middle and high school are as follows； 1. The aim of cooking practice： It should be first of all remembered that the practice is so practical that the knowledge and skill of cooking should be related to the future domestic life. Second, the practice should be able to serve the communal and national life by scientifying and improving life. 2. The content of the practice： First, it should be so arranged step by step that the content of each year should not be repeated. Second, the ratio of Korean cooking practice should be increased and the material of the practice should be chosen in consideration of the peculiarity of the community, seasons and economical problems so that it may be applied to the very day life. Third, to improve dietary life, the practice should be a way of the simplification of dietary life, of the nutritional efficiency. Forth, for the betterment of physical condition of the family the practice should involve balanced dietary plans and dietary therapy. 3. Teaching method： First, the practice should be scientific and comprehensive in consideration of not only cooking skills but also knowledge of nutrition. Second, micro-class system should be adopted, and practice labor should be allotted each student to develop cooperative attitude and the sense of responsibility. Third, in addition to the practice conducted in a body, comparative cooking, applicable cooking and experimental ability and the content of the text. Fourth, teachers should let the students examine and find problems by bringing them to a focus on the basis of theory. 4. Administration method： First, the practice schedule should be planned that a class has practices at least more than twice a semester. Second, two hours of class should be continued without cessation after beforehand survey and theory study. Third, facilities and utensils for practice should be enlarged. That is, cooking practice rooms, tools, utensils should be prepared. Fourth, enough cost of practice should be secured. The above mentioned points show the present situation and problems with which cooking practice teaching is confronted. In order to normalize cooking practice teaching, the first-line schools should give the above mentioned problems their careful consideration and improve the present situation so that efficient, creative, practical cooking practice will be possible.

In Chinese medicine, the activities of removing and solving the inner cause are called the regimen in preventing the disease and the good condition of mind emphasizes us to practice ourselves the doctrine of regimen of the mind to promote the health and long life of the living body, in other words, it means we should have clean mind, less desire, less thought, less agony and widely open our emotion and will, and it also means the raising of good nature, the moral cultivation, and we can be healthy when we live by good virtus as the root of regiem. The meaning of the Qi has been expanded more and more since its origination throught the process of practice and perception of man. 1) Matter is changed to the smoke when burned, the energy of water becomes the rain in the sky and the rain raises all living creatures by making them wet. Throught these changes of circulation, men could realize the energy to be the common and original matter of forming all the creatures. 2) The direction of showing the breathing of men in and out has been expended. 3) It was widely understood as the meaning of showing vitality of men, and it was the original root of chinese medicine. 4) It was expended to be showing spirit of nature such as the sun, moon, star, sky, land, mountain and the moral spirit of men as peacefullness. By the original meaning of the word of energy expanded to the wider side of sky, land, men and things, nature, society, man and the moral spirit could get the unified basis of the matter. As the above, the word of Qi has been used in wider meaning at this time from the past. In other words, all things in the universe come into being and extinct by the chang of motion of the Qi and it is recognized to be the living activity in human body. The Qi-kong based on this energy and the motion applied to our daily life are very extensive (Lee, Hye - lung, 1997). Here are the summaries of the effect of the Qi-kong ; 1) The physical constitution is strenthened, physiological function is prosperous and we are free from various geriatric disease and psychosomatic disease not to mention the cold and indigestion. 2) It maintains the clear spirit, elevates intelligence, strengthens the spiritual power and demonstrates the potentiality at the amximum. 3) It maintain beautiful figure and clean skin never losing the charm but full of energy and vitality. 4) It keeps the balanced body never suffering from the unbalance of the bones, various and neuralgia. 5) It maintain the spiritual comfort, the natural posture in everything and real happiness (Lee, Hye-Jung, 1997 : Suh, Yong Kyu, 1989). Chinese medicine mentions the motion by Qi with Qi - kong. But the motion does not require special method in Western medicine. I t is the only way of living of our ancestor indaily life. It is maintaining the healthy lifr by training the Qi, and it is the motion of being with the nature with the open mind in breathing rather than artificially restricting our daily life, it is the motion of the body.

Purpose : When the pliability of the Lumbar is degraded, the kinesiology function undergoes an influence and it receives an overload. Finally, it is connected with a Lumbar muscular injury. When it does the regular exercise treatment the lumbago patient the balance and function of changeover are improved. The purpose of this study is to review of effect of the PNF application for lumbago patient Methods : By using internet, we research the PubMed, Science Direct, KISS, DBpia and the article on the effect of PNF. We selected the article between 1970 and 2007. Key words were low back pain, lumbago, PNF. Results : PNF is a therapeutic exercise for central nervous system(CNS) patient and the peripheral nervous system(PNS) patient and it is widely applied from sports medicine in the last. According to research of the Jung Young Jo(2007) and Han Kou Soo(2002), PNF technique improves the pain and a condition of the lumbago patient. And the affection balanced change and dynamic balance change and spontaneous movable scope are improved. And it improved to daily life activity. According to research of Moore and Hutton(1980), Lee Kyoung Hye(1999), PNF stretching where it is one of muscular relaxation is good in lumbar muscle fascia ache solutions, and PNF stretching that muscle is relaxed and increases ROM by Reflective system of the vertebra. These researches is relation all each other. it have appeared many report of research about Pliability, muscular power, balance, mobility improve ADL movement of attendance ability and functional action improved excise therapy put effect about lumbago patient recently, it have appeared research about therapy of lumbago patient through PNF. But PNF technique is not application about lumbago patient in clinic, therefore also it is not enough for case study about this therapy. Conclusion : PNF improve combination operation of muscle, inconvenience decrease from daily life activity, ROM(range of movement) of lumbar is increase and Lumbago reduce. So we suggest that PNF will be applies on the lumbago patient and must do a many research.

Objective: Melatonin, which is secreted by pineal gland play an important role in the regulation of ovarian function via seasonal rhythm and sleep in most mammals. It also has a role in the protection of cells by removing toxic oxygen free radicals brought about by metabolism. In the present study, effects of melatonin on the mouse oocyte maturation were examined using two different culture conditions provided with 5% or 21% oxygen concentration. Material and Method: Immature mouse oocytes were obtained from the ovarian follicles of $3{\sim}4$ weeks old ICR strain mice intraperitoneally injected with 5 I.U. PMSG 44 hour before. Under stereomicroscope, morphologically healthy oocytes with distinct germinal vesicle (GV) were liberated from the graafian follicles and collected using mouth-controlled micropipette. They were then cultured for 17 hour at $37^{circ}C$, 5% $CO_2$ and 21% $O_2$ (95% air) or 5% $CO_2$, 5% $O_2$ and 90% $N_2$. New modified Hank's balanced salt solution (New MHBS) was used as a culture medium throughout the experiments. Effects of melatonin were examined at a concentration of $0.0001{\mu}M$, $0.01{\mu}M$ or $1.0{\mu}M$. For the prevention of spontaneous maturation of immature oocytes during culture, dibutyryl cyclic AMP (dbcAMP) and/or hypoxanthine were included in the medium. Results: Under 21% oxygen condition, oocytes cultured in the presence of $0.01{\mu}M$ melatonin showed a significantly higher maturation rates, in terms of germinal vesicle breakdown (95.0% vs 89.0%) and polar body formation (88.1% vs 75.4%), compared to those cultured with $0.0001{\mu}M$ or $1.0{\mu}M$ melatonin. However, no difference was observed in oocytes cultured under 5% oxygen whether they were treated with melatonin or not. In the presence of $0.01{\mu}M$ melatonin, oocytes either cultured under 21% or 5% oxygen exhibited no difference in the polar body formation (85.6% vs 86.7%). However, in the absence of melatonin, oocytes cultured under 21% oxygen exhibited lower polar body formation (74.7%). When oocytes were cultured in the presence of dbcAMP alone or with varying concentrations of melatonin, those treated with both compounds always showed better maturation, i.e., germinal vesicle breakdown and polar body formation, compared to those cultured with dbcAMP alone. At the same concentration of melatonin, however, oocytes exposed to 21% oxygen showed poor maturation than those to 5% oxygen. Similar results were obtained from the experiments using hypoxanthine instead of dbcAMP. Conclusion: Based upon these results, it is suggested that melatonin could enhance the meiotic maturation of mouse oocytes under 21% oxygen concentration, and release oocytes from the meiotic arrest by dbcAMP or hypoxanthine regardless of the concentration of oxygen, probably via the removal of oxygen free radicals.

This study did derive a characteristic of a cover design through considering a concept, a function and components of a cover design based on a literature study and through analyzing cases of the best-seller cover designs for the literature section from 1999 to 2002. In terms of a reader's preference for a cover design according to an age and sex of a reader, it tried to suggest a condition and a method of a book-cover design through a questionnaire survey and the image evaluation. In a survey of the preference for a cover design, there was the difference of interest degree in a kind of a book, a place to buy a book and a cover design according to an age and sex. In addition, it was shown that a woman prefers the stylish typography, and both a man and a woman prefer the cool color. However, except these two, the reason why there is no difference in preference for visual elements are that a cover design is an integrative image comprising several elements. Accordingly, through the Semantic Differential Method, it carried out the evaluation as to a cover design as an integrative image. As a result of that, an abstract image was shown to be difficult to convey a meaning because of its fall in clarity. Further, a cover design mainly comprising the stylish typography gained the high evaluation in unique and clarity. It is thought to be attributable to the easiness to achieve a goal of seeing and reading in a cover design in which an image and the typography are balanced, rather than the excessive visual. Even though the visual is excellent, there was difference from what having been excellent in conveying a meaning, which is a functional aspect. This study tried to examine, limiting it only to a visual element. It will be hereafter required to proceed with a study on the influence on a reader's preference according to material, bookbinding and a form of book which are elements comprising a cover design.

The first drainage time in a day was controlled for precise irrigation management with low consumption of nutrient solution in tomato perlite bag culture system by measuring water level of drained water in drainage catchment part. This method automatically adjusted the irrigation time under any condition of light, temperature and humidity, resulting in stable water content in substrates. However, it was difficult to keep the time consistent as they were set. It drained with the deviation of 20 min in the treatment in which the first drainage time was set at 10:00 and 50 min in the treatment set at 10:30. The first drainage time was not constant, but the drain occurred stably before noon in the treatment of which irrigation frequency was longer than 30 min. The drainage ratio was better balanced in all the treatments using drainage level sensors than the treatment using time clock for irrigation control. High water and fertilizer efficiencies were obtained. Although the growth, total yield and sugar content were not significantly different between the treatments, fruit weight was higher in the treatments using drainage level sensors than that using timer.

The changes in the dietary pattern of Koreans during the last one century and its consequences are summarized as follows; 1. Until the beginning of 20th century, Koreans used variety of cereals, vegetables and fruits for their staple food, but the variety has been largely reduced by the agricultural development and urbanized life style. 2. The well balanced traditional dietary pattern of Korean had been deeply deteriorated by the food shortage during the Japanese occupation and Korean war. 3. The deteriorated nutritional condition of Korean was not remedied by the restoration of traditional dietary pattern, but attempted to overcome it by the adoption of Western food habit. 4. The people were trained to eat milk and flour-meals during the starvation of Korean war, and it was continued after Korean war through the animal husbandry promotion policy. 5. The importation of food and feed cereals has been increased rapidly during the economic growth in 1970's and the food self-sufficiency droped below 50%. 6. In 1970's, the food supply pattern of Korean was restored to the level of early 1900, but the consumption of lipid increased extraordinarily. 7. The overconsumption of animal food and lipid continues in 1980's, and it coincides with the rapid increase in the occurence of food related degenerative deseases. 8. The establishment of Korean dietary goal which is based on the traditional dietary pattern is needed.

The ultimate goal of the present study is to establish the acoustical performance standards of classroom for the elderly who are incomplete hearing people. As a pilot survey, the present study was conducted to investigate the listening environment and the actual condition of speech perception performance of education facilities for elderly, Acoustic performances of two education facilities for elderly in Cheongju were measured and questionnaire survey was done to elderly people. Also, speech intelligibility tests were undertaken by Consonant Vowel Consonant (CVC) and Phonetically Balanced Words (PBW) methods. The questionnaire survey showed that the elderly were satisfied with the listening environment of the educational facilities in general. Also, it was found that acoustical performances satisfy with the acoustic criteria of general classrooms in Korea. However, the results of the speech intelligibility test showed that the scores of elderly were significantly lower than twenties with normal hearing. It was also revealed that the scores are reduced as the age increases. Thus, it was concluded that the acoustical performance standards of educational facilities for the normal hearing were not suitable for educational facilities for the elderly.

This study analyzed the usage characteristics and requirements of students who are users of the middle school education space, and the following results were obtained: First, we could see that various types of classes were needed, such as lecture-style classes, team projects, and four-person consultation and discussion classes, in a way that helped to improve the desirable teaching patterns and learning ability. Second, the place where space was used during the break and the relationship between peers, revealed that most of them were in the classroom and the hallway, and the peer group was composed of three to eight people or more, that were active with various compositions. Third, a gym, library, toilet, stairway, cafeteria, nurse's office, and teachers' room appeared in the center of the building, indicating the need for a balanced layout. Fourth, physical education (dance) rooms, audiovisual rooms (performance rooms), workshops (personal creation), snack bar, rest area, spacious indoor square, and study rooms were needed as facilities that can help learning activities other than current facilities. These outcomes show that the existing classroom layout and space composition formats require some spatial restructuring.

This research studied the effect of visual improvement of "72 Hour Project" that has regenerated small scale derelict spaces in Seoul through citizen participation. 29 projects built form 2016 to 2019 were analyzed. The research analyzed landscape image preference of before and after status of projects using 12 pairs of landscape adjectives. Basic statistical analysis, correlation analysis, factor analysis, cluster analysis, and ANOVA were performed based on the survey results. Since the satisfaction level of the projects compared with the before-condition was 3.63 higher than 3.00, it could be concluded that there was an meaningful effect of visual improvement after completion of the projects. As the result of the factor analysis, landscape adjective pairs were categorized into two factors: harmony and aesthetics. Through the cluster analysis, four clusters were formed and characteristics of each cluster were identified. As the result of rhe cluster analysis, the cluster with the high harmony level and the aesthetics level showed the highest overall satisfaction level. Comparing each cluster, it could be concluded that the factor of harmony was more important than the factor of aesthetics in evaluating the satisfaction level of projects. Analyzing qualitative aspects of project groups, spatially well-balanced design with generous vegetation areas was more effective in landscape improvement than artistic design with visually strong installations. Further researches based on behavior studies of actual users are required to compensate the limits of this research. This research can contribute to establish the improved direction of policies to regenerate various types of small scale derelict spaces.
