This study was designed to investigate the relationships between children's physical growth and health and their raising conditions and to find out the important conditions to improve their physical growth and health. The rasing conditions were classified into three major parts; i. e., family conditions, conditions of nutrition up-taking, and conditions of rest or sleep and exercise or play. Then, the questionnaire including the items to survey these three areas of raising condition and the items to evaluate the health status were given to children' mothers or fathers and filled up by them. The data of their 4 anthropometric measures; body weight, stature, sitting height and chest girth, were also collected from their latest records of health examination. The data of health status were converted to health scores representing 6 domains of health; digestive organs, respiratory organs, auto-nerve systems, fatigue, others and health as a whole. Then, correlations of raising conditions were determined with four antropometric measures and 6 health scores as criterion variables. Then, number of families to live together, and child's birth order in the domain of family conditions, habits of unbalanced diet, eating frequency of eggs, fruits, green and yellow vegetables, light colored vegetables, milk products in the domain of nutrition up-take, and the time for study at home, the place for play, the number of friends to play with together, the hours for playing out of door, the hours for playing sports, and the hours to move their body for assisting house keeping were picked out to investigate their relationships with physical growth and health status. Then, their habits of unbalanced diet and eating frequency of eggs, green or yellow colored vegetables, and milk products were found more influential conditions and more over, birth order, the time for study at home, the time to play out of door showed moderate degree of connection with physical growth and health status in early childhood.

고가의 식품으로 이용되는 말똥성게의 생식소의 소비가 증가됨에 따라 연안의 말똥성게 자원은 계속 감소하고 있어 이 종류에 대한 양식 기술개발은 중요한 연구 과제이다. 따라서 본 연구는 말똥성게를 실내에서 양식할 경우 먹이로서 신선한 해조류를 대치할 수 있는 육상식물을 조사하였다. 해조류 6종류 (미역, 구멍갈파래, 지충이, 개지누아리, 모자반, 곰피), 육상식물 5종류 (시금치, 상치, 무우잎, 배추, 케일), 동물성 먹이 2종류 (바지락. 쇠고기)를 대상으로 말똥성게의 선택적 및 비선택적 식성과 영양 효과를 비교한 결과, 말똥성게의 먹이로서 육상 식물의 이용이 가능하였다. 미역을 공급한 경우 말똥성게의 체중의 성장은 가장 높았으나 생식소지수는 시금치, 무우잎 또는 상치를 공급할 경우가 미역의 경우보다 더 높았다. 시금치와 무우잎의 공급은 생식소가 성장하는 계절에 적합하고, 각이 성장하는 시기에는 상치 또는 배추가 효과적일 것으로 판단된다. 특히 무우잎은 식용으로 이용하지 않고 버려지므로 무우잎을 이용한 말똥성게의 양식은 매우 경제적일 것이다.

Nutrition is an essential component of total adolescent health care. Two important changes occurring during adolescence can cause a crisis in the teenager's nutritional needs. First, growth in height, weight, and body component is greater and more rapid than at any time since infancy. Second, an adolescent's eating habits may change from regular meals prepared at home to irregular meals, skipped meals, and nutrition-poor snacks and fast-food meals. Adolescents have been found to have the highest prevalence of any age group of an unsatisfactory nutritional status. To understand the nutritional requirements of the adolescent, health practitioners should be aware of the intensity and timing of the adolescent growth spurt, the differences in the growth spurt between males and females, and the individual variation in timing of the growth spurt from teenager to teenager.

Background: Most fish undergo prey switch from juvenile to adult. It is thought that slightly different feeding habits occur among adult fishes due to growth, spawning, habitat change, and so on. Therefore, the diet of the John Dory Zeus faber (≥ 24 cm TL) was studied in the coastal waters of Korea by analysis of stomach contents, with comparison by season and size class of diet composition and prey diversity. Monthly samples were taken from February 2017 to January 2018. Results: The results showed that the John Dory was a piscivorous predator, and pisces had occupied 82.3% of IRI%. Trichiurus lepturus and Trachurus japonicus were important preys in all size classes and seasons. Diet composition differed among the size classes and seasons (Chi-square test, P < 0.05). As body size of Z. faber increased, the occurrence of benthic fish (Glyptocephalus stelleri) tended to increase. The seasonal prey composition also changed depending on the abundant species of each season. Conclusions: Z. faber is a piscivorous predator. The consumption habits of Z. faber appear to different results by their size and seasons. This study suggests that Z. faber could be considered an opportunistic predator.

single crystals of various hexagonal ferrites were grown by a flux technique. For the growing experiment platinum crucibles of size 40 cc and a horizontal siliconit tube furnace were used. Charges consisted of the flux of BaO(SrO)/$B_2O_3$ and the composition of crystals in the system of BaO $(SrO)-Fe_2O_3-ZnO$. The BaO(SrO)/$B_2O_3$ molar ratio of the flux were varied from 1 to 3. Crystals up to 12.5mm in diameter were grown by slow cooling of melts from a maximum temperature of 1, 30$0^{\circ}C$or 1, 350$0^{\circ}C$ to 95$0^{\circ}C$ or 1, 00$0^{\circ}C$ The grown crystals exhibited a tabular hexagonal habits with very well developed ba-sal planes and narrow pyramidal faces of {1011} {1012} and {0001}. For the identification of the grown crystals X-ray diffraction studies were carried out. The effects of va-riations in flux ratio flux percentage and cooling rate on the quality of the grown crystals were studied. Cry-stal habits hillocks etch steps and growth spirals were observed by optical microscope. Magnetic properties of single crystals were measured.

Field classes are necessary to grow the ability of and an attitude toward exploring nature and to shape the basic concept of natural science. I tried to develop a site for field classes and the old road Naori's hill is an ideal place with convenient traffic and established youth camps. As a result the vegetation was divided into five associations and communities. The vegetation units obtained in the present study were as follow: Quercus acutissima community, Pinus densiflora community, Pinus densiflora-Quercus acutissima community, Quercus acutissima-Pinus densiflora community, and Quercus mongolica community. In all survey areas 100 family 336 genus 587 species of palants was found. Furthermore, it provides lots of plants throughout the seasons. Not only the flora but also flowering phenology, variety of floral color and growth habits can be used as teaching items. Incorporation of diverse knowledge of plants at the old road Naori's hill into biology teaching will give students academic stimuli and teachers an opportunity of retraining. With a combination of use of visual instruments, the purpose of conceptual and exploring biology is more easily achieved.
