본 연구는 초등학생의 유튜브 이용실태와 동기를 확인하고, 유튜브 이용과 부모양육태도, 자아존중감, 학교생활만족도와의 관계를 규명하고자 하였다. 이를 위해 초등학교 4, 5, 6학년 재학생 238명을 대상으로 유튜브 사용량과 동기, 부모 양육태도, 자아존중감, 학교생활만족도를 측정하였다. 연구 결과, 조사 대상 초등학생의 과반수는 하루에 1시간 이상 유튜브를 이용하고 있으며, 전체의 15.6%는 하루에 3시간 이상 유튜브를 이용한다고 응답해, 초등학생들의 상당 수가 매우 적극적으로 유튜브를 사용하고 있음이 드러났다. 유튜브 이용빈도가 높을수록 부모의 애정, 자아존중감, 학교생활 만족도는 낮은 편이었다. 또 부모의 애정적 양육태도는 초등학생의 유튜브 이용빈도를 부분매개하여 적응에 영향을 미치는 것으로 드러났다. 반면 거부적 양육태도 및 과보호적 양육태도의 경우 유튜브 사용량과 큰 관련성이 없었으며, 매개효과도 발견되지 않았다. 본 연구의 결과는 초등학생의 과도한 유튜브 이용의 구체적인 심리적 악영향을 밝힌 국내 최초의 경험적 연구로, 초등학생의 유튜브 이용에 대한 적절한 가이드라인이 필요함을 시사하였다. 또한 아동의 유튜브 이용에 있어서도 부모의 양육태도가 관여할 수 있음을 보여주었다.

Knit products which had been limited only to underwear, recently became popularized, fashionized and highly classified covering even outer garments such as sportswear like golfwear, woman's dress, and man' s suit. As fashion cycle is getting shorter and the more a nation advanced prefers knit to woven fabrics knit industry has a very bright prospect, particularly woman's knit which is sensitive to fashion can be said as a fashion product with high value added. This study is to grasp the physical properties of stitch which are fundamental to the development of knit products. For this purpose, 2/20s of 100% wool were woven by the author of this study to basic plain stitch, rib stitch, varied transfer stitch, and float stitch on a SEMASEIKI cross knitter 7G to test the physical properties, and the result was as follows; 1. As for the relation between knit stitch and rate of extension recovery, rate of extension recovery was higher in the course direction than in the wale direction of three stitches except transfer stitch; rib stitch showed the highest rate of extension recovery in the course direction while float stitch showed the highest rate of extension recovery in the wale direction. 2. As for the relation between knit stitch and bursting strength elastic rib stitch showed higher bursting strength to indicate elasticity is an important factor of bursting strength and float stitch showed higher bursting strength too to indicate that the floating yarn on the surface plays a role of support. 3. As for the relation between knit stitch and air permeability perforated transfer stitch showed the lowest air permeability to prove that the size of perforation affects on the air permeability a great deal. 4. As for the relation between knit stitch and warmth retaining rib stitch through two lined needle bar showed the highest degree. The reason the warmth of perforated transfer stitch didn't decrease much was because the perforation wasn't big enough and content of air increased from the unevenness of the perforated parts through stitch variation. Based upon this result, each stitch can be characteristically summarized as follows; plain stitch showed a stable condition of knit cloth in four kinds of physical property test. And rib stitch is proper to tighten the edge of sleeve or clothe making use of its excellent extension recovery and to make socks for the highest bursting strength and warmth retaining. In the case of transfer stitch, seasonable designs can be taken by controlling the size of loop. Considering the pleasantness, underwear should be made of stitches with good air permeability float stitch was revealed to have color and pattern effects and a great bursting strength. This study has limitations in the aspect that it dealed with a small part of various knit stitches and the items of physical property test were not enough. The author of this study hopes that further studies would make deeper understandings about knit stitch based on more varied stitches and physical property tests ultimately to contribute to the development of fashionable designs proper to maximize the usage, function and originality.

Accumulation of soil organic matter and its vertical distribution at different latitudes in peninsular Korea were studied in the soil of four different forest types viz. Pinus densiflora forest, Castanea forest, Quercus acutissima forest and Carpinus laxiflora forest. Among them, accumulation of soil organic matter in Cheju sites, with a mean annual temperature of 15$^{\circ}C$, was maximum with increasing latitude, soil organic matter concentration decreased. Considering the relationship between concentration of soil organic matter and some climatic conditiions, it seems that concentrations of soil organic matter is a function of annual temperature, especially warmth index or cold index.

This study investigated the relationships among individual factors, family factors, peer relationships and the internalizing and externalizing behaviors of adolescents. The data were obtained from a sample of 417 7th and 8th grade students. These data were collected with questionnaires and analyzed by using a t-test, Pearson's correlation, and a multiple regression analysis with SPSS ver. 18.0. The results can be summarized as follows. There is a significant difference in an adolescent's self-control, their father's rejective rearing, peer pressure, and the peer relationship between boys and girls. The results showed that boys had higher self-esteem and father's rejective rearing than girls. On the other hand, girls had higher peer pressure and more intimate peer relationships than boys. The results revealed that the 7th grade students had higher self-esteem and mother's warmth rearing than the 8th graders. Furthermore, the 8th grade students showed higher shame, mother's rejective rearing, marital conflict, internalizing behavior, and externalizing behavior than the 7th graders. The internalizing behavior in boys was influenced by shame, marital conflict, and peer pressure. In the case of girls, the internalizing behavior was affected by shame, mother's warmth rearing, and peer pressure. The externalizing behavior in boys was influenced by self-control and shame. In the case of girls, the externalizing behavior was affected by self-control, shame, marital conflict, and peer pressure. Adolescents who exhibited higher levels of shame than others and higher peer pressure showed internalizing problem behaviors. Adolescents who had less self-control and more shame, experienced more externalizing behavior problems.

The purpose of this study was to examine the effects of child rearing behavior and child rearing involvement on elementary school children's stress. The subjects were 201 children selected from 2 elementary schools and their parents. Data was collected using the children's stress index, the child rearing behavior questionnaire, and the child rearing involvement questionnaire, and was statistically analyzed using t-test, one-way ANOVA (Duncan test), correlation analysis and multiple regression analysis. The study showed that there were some significant differences in children's stress according to the child's gender, grade, and scholastic achievement. Correlation analysis indicated that the child's stress and the mother's child rearing behavior had significant correlation, especially the warmth acceptance behavior of the mother indicated negative high correlation. Also, the child's stress and father's child rearing behavior had significant correlation, especially the rejection restriction behavior of the father indicated positive high correlation. Correlation analysis indicated that the child's stress and the mother's child rearing involvement had significant correlation, especially the family activities involvement of the mother indicated negative high correlation. As well, the child's stress and the father's child rearing involvement had significant correlation, especially the day to day guidance involvement of the father indicated negative high correlation. It was also found that rejection restriction behavior of the father, permissiveness non-intervention behavior of the father, day to day guidance involvement of the father, family activities involvement of the father, and warmth acceptance behavior of the mother were all significant predictors of the elementary school child's stress.
