The study was conducted to determine the inherited properties of the MEB resistance to natural population of the small brown plant-hopper(Laodelphax striatelluss). The plant-hoppers were collected from the natural population of Naju area where the highest insecticide resistance of MEF to the green rice leaf hopper (Nephotettix cincticeps) have been examined in 1976. And Naju collections were crossed to the susceptible Lab stock to examine the MEP resistance in the $F_1,\;BC_1F_1\;and\;F_2$ and $F_2$ populations. Ail the data were analyzed by the probit method. There was a difference in MEP resistance between Naju collection and susceptible Lab stock, showing $LD_{50}$ value of the former was 0.0029ug/insect compared to 0.0008ug/insect for the later. The $LD_{50}$ values and dosage-mortality lines of the $F_1$ and $BC_1F_1$ tended to close their resistant parent. and it was considered that the character of the MEP resistance in the Naju collection of the small brown plant hopper was controlled by the genetic traits. However, $LD_{50}$ value and dosasage-mortality lines of the $F_2$ populations were intermediate to their parents, it would be conclusive that the trait will be governed by a interaction of the genes or factors rather than the single genic control.

The purpose of this study was to examine the nature of psychopathology and psychosocial environments of children with Atopic Dermatitis(AD) and their relationship to skin symptoms. Seventy outpatients with AD(mean age 9.94, range 4-15 years) and their mothers were subjected to psychiatric interview and parent- and self-report questionnaire(CBCL, MBRI, CDI, Spielberger's State-Trait Anxiety Inventory for Children(STAI), Family Impact questionnaire). Disease severity was assessed in three dimensions(skin extent, disease activity, and subjective symptom) by SCORAD index. Sixteen(22.9%) of our sample were suspected to have behavioral-emotional problems and they were different from non-problem group on depression, trait-anxiety, maternal controlling attitude and negative appraisal of children. While skin inflammation activity was correlated with only trait-anxiety and depression, subjective skin symptoms were correlated with many psychosocial factors such as depression, state-and traitanxiety, family-impact, social competence, internalized and externalized behavioral problem, sexual problem, and mother's positive appraisal of children). We concluded that children with AD are highrisk group for behavioral-emotional problems, and these problems along with maternal negative parenting attitude can affect their subjective symptom experience.

Private education expenses is one of the key issues in Korea and there have been many discussions about it. Academically, most of previous researches for private education expenses have used multiple regression linear model based on ordinary least squares (OLS) method. However, if the data do not satisfy the basic assumptions of the OLS method such as the normality and homoscedasticity, there is a problem with the reliability of estimations of parameters. In this case, quantile regression model is preferred to OLS model since it does not depend on the assumptions of nonnormality and heteroscedasticity for the data. In the present study, the data from a survey on private education expenses, conducted by Statistics Korea in 2015 has been analyzed for investigation of the impacting factors for private education expenses. Since the data do not satisfy the OLS assumptions, quantile regression model has been employed in Bayesian approach by using gibbs sampling method. The analysis results show that the gender of the student, parent's age, and the time and cost of participating after school are not significant. Household income is positively significant in proportion to the same size for all levels (quantiles) of private education expenses. Spending on private education in Seoul is higher than other regions and the regional difference grows as private education expenditure increases. Total time for private education and student's achievement have positive effect on the lower quantiles than the higher quantiles. Education level of father is positively significant for midium-high quantiles only, but education level of mother is for all but low quantiles. Participating after school is positively significant for the lower quantiles but EBS textbook cost is positively significant for the higher quantiles.

To evaluate the relationship between eating behavior and neurotic trait in middle school students, the authors applied eating scale, Middlesex Hospital Questionaire and Zung's self-reting depression scale to 419 middle school students(male : 187, female : 232) in Taegu city in 1993. The results were as follows : There was no significant relationship between weight devided groups. Female middle school students showed significant high scores(p<0.05) in all scales compared to male middle school students. The correlation between eating scale and the other two scales showed significant correlationship(p<0.05). Among psychosocial factors, the items related to dissatisfaction to present and future self image(each p<0.05, p<0.05), dissatisfaction to present environmental status(p<0.05) and dissatisfaction to future attitude showed significant high score in both sex. The item related to dissatisfaction to present interpersonal relationship (p<0.05) showed significant high score in male middle school students. The items related to eat consumption rate of 61-90%(p<0.05), unsatisfied to relationship with family(p<0.05), unsatisfied to childhood family atmosphere(p<0.05), unsatisfied to past self image(p<0.05) and unsatisfied to present relationship between parent(p<0.05) showed significant high score.

e-Learning has been mushrooming with wide range of learning groups from pedagogy to andragogy. Despite of increasing e-learning opportunities, many people doubt whether e-learning learners really learn something. The related research papers emphasized that e-Learning would be a failure in terms of understanding of e-learners and intuitive learning activities for activating learner's long-term memory span. The current learning strategies in e-Learning may be based on the traditional classroom, and this results in boring and ineffective learning outcomes. This paper analyzed that how learners have received e-Learning for the last few years from the research and explained what could be the failing aspects of e-Learning. To be successful, e-Learning should consider the e-Learner's individualized teaming style and thinking patterns. When considering of various e-Learning components, the quality of e-learning should not be focused on any specific single factor, but develop every individual factor to the high level of quality. In conclusion, this paper suggest that we need new understand of e-Learning and e-Learner. Also the e-Learning strategies should be examined throughly whether they are on the side of learners and realized how they learn from e-Learning. Finally, we should add enormous imagination into e-Learning for next generation because their teaming patterns significantly differ from their parent's generation.

e-Learning has been mushrooming with wide range of teaming groups from pedagogy to andragogy As e-teaming opportunities increase, many people raise question about whether e-teaming show positive teaming effects. The related research emphasized that e-learning would be a failure in terms of understanding of e-Learners and activating intuitive teaming activities from learner's long-term memory span. The e-teaming strategies based on the traditional classroom and resulted boring and ineffective teaming outcomes, should be changed to provide authentic and effective teaming results. This paper analyzed that how learners have received e-Learning for the last few years from the research and explained what could be the failing aspects in e-Learning. To be successful, e-loaming should consider the e-learner's individualized teaming style and thinking patterns. When considering of various e-Learning components, the quality of e-teaming should not be focused on any specific single factor, but develop every individual factor to be integrated into high level of quality. In conclusion, this paper suggest that it is needed new understandings of e-Loaming and e-Learner. Also the e-Learning strategies should be examined throughly whether they are on the side of learners and realized how they learn from e-Learning. Finally, we should add enormous imagination into e-loaming for next generation because new generation's teaming patterns significantly differ from their parent's generation.

In this study, a prediction model for depression among parents with disabled children was developed by verifying the effects of social support and family resilience. One hundred forty one parents with disabled children were recruited from three out-patient clinics of rehabilitation hospitals in D city between August and September, 2014. The instruments used were the QRS, CES-D, MSPSS, and KFSS-II. The average score of depression was 20.18/60. The levels of depression were significantly different among variables, e.g., sex, age, and monthly income. The mean scores of the item for social support and family resilience were 3.11/5 and 3.32/5, respectively. Family resilience differed significantly according to monthly income. Parental depression was negatively correlated with the social supports and family resilience. Social support was correlated positively with family resilience. In conclusion, family resilience and social support are predictable factors for depressed parents with disabled children.

Our country has become an aging society with unparalleled speed, compared to other advanced countries. Many of the elderly are physically, economically, and psychologically dependent; this dependence is a factor that increases the cost burden not only on the children and relatives of the elderly, but also at the social level. Under the prevailing environment of the family-oriented informal support system, the burden of support for elderly parents who rely on limited resources is highly likely to lead to abuse. Until now, dealing with the abuse of senior citizens has been mostly a one-off approach through media rather than academics. Therefore, this study attempts to take an objective approach to the elder abuse problem (which has so far been dealt with in the media as a form of domestic violence) in order to grasp the specificity and factors of elder abuse and to present the Korean situation with regard to elder abuse. In addition, this study seeks to find ways to prevent elder abuse in formal and informal ways.

The satisfaction of elementary school children and their parents with the school lunch program by foodservice system was assessed by questionnaire. The subjects Participated in this survey were 1,136 students, first-6th grade elementary school children and 1,140 parents in Seongnam area. The result was as follows: the satisfaction score for school lunch program by foodservice system was rated as 'high'. Students' and parents' satisfaction score were 3.63 point and 3.62 point (5-point Likert rating scale), respectively. Difference of satisfaction score by grades was that high grade students were significantly lower than low grade students' (P<0.001). Five grade students' score was 3.23 point and 2 grade students' score was 4.04 point. Children's favorite food types were meat, dessert, cooked rice and fried food. The least preferred food types were green and seasoned vegetable, kimchi, soup and fish. Students felt shortage of favorite foods and a lot of dislike foods. Parents answered that thorough sanitary management (22.5%) and use of good quality foodstuffs (11.5%) were the most important factors in improvement of the school lunch program.

The working concept of the disadvantaged gifted is meant by those who hardly can have a chance to develop one's own gifts because of the environmental conditions and factors. The main purpose of this study is to explore the inherent trait of the music giftedness, which is composed of musical ability, creativity, and task commitment. Grounded upon the phenomenal research, this study purposefully samples ten disadvantaged students who participated in the arts gifted camp hosted by Korean National Research Institute for the Gifted in Arts. Thus, it explores the inherent traits of the disadvantaged gifted by coding, segmenting, and analyzing the interview with ten disadvantaged, and the evaluation reports of the expert group. The inherent trait of music giftedness of the disadvantaged gifted is shown as this: the inherent trait of the disadvantaged gifted in music is closely interrelated with one's own concept of giftedness. Whereas they show the high motivation and task commitment, they are hardly observed to have the creativity in their musical activities and learning. Finally, this study give a proposition for the strategy to stimulate and improve the inherent trait of the disadvantaged gifted in music: the importance of parents education and parent screening, meta-cognitive skills, the leaning-based creativity education, and the significant role of intrapersonal catalyst.
