Objectives：This study was designed to investigate the temperamental characteristics and the differences of temperamental characteristics in Korean children according to the sociodemographic and family environment factors using Toddler Temperament Scale(TTS). Methods：The samples consisted of 1,175 children who were attending twenty-five Samsung Child Care Centers nationwide. Both Korean version of TTS and child developmental questionnaire(designed by the Department of Psychiatry, Samsung Medical Center) were distributed to the parents of these children. Score of 9 temperamental categories was determined using the result of TTS, and determination of 5 temperamental clusters was conducted by the Fullard's criteria. Statistical analyses were performed according to the sex, birth order, existence of siblings, residential city, residential province, marital state of child's parents, and parental relationship to compare the scores of temperamental categories and the distribution of temperamental clusters. Results：The distribution of temperamental clusters was as follows；Easy 35.8%, Intermediate Low (IL) 33.1%, Intermediate High(IH) 11.1%, Slow-To-Warm-Up 6.3%, and Difficult 13.6%. Some of 9 temperamental categories were statistically different according to the sex, birth order, existence of siblings, residential city, residental province, marital state of child's parents, and parental relationship. From the viewpoint of 5 temperamental clusters, there were statistically more Easy and less Difficult children in good relation between each parent(p=.022). In spite of no statistical significance, the children in conditions of first-born, non-existence of siblings, middle or small residential city, Chung-Cheong province, married state of parent had a tendency to be easier to care. Conclusions：The toddler temperamental characteristics of Korean children showed some differences in several sociodemographic and family environment factors. We could confirm that the 'Goodness of Fit' was very important in child temperament.

A total health state evaluation of Korean female elderlies was made by using the questionary scheme measuring the physical, mental and social functions of the elderlies, in order to investigate the critical factors for the health maintenance of female elderlies and to develop their preventive nursing program. A total of 280 subjects over 65 years old living in Seoul and the suburban area were selected and interviewed during the period of September and October in 1995. The materials collected were analyzed statistically by using SAS data processing program, and the results and recommendations are summarized as follows. 1. The physical health state of Korean elderly women was evaluated to be satisfactory by showing an average score of 3.722 in 5.0 full-score scale. But this score was lower than those evaluated for the elderlies combined both sexes(4.054). The mental health state of the subjects was also evaluated as high scoring 3.484, possibly due to the fact that 78% of the subjects lived together with their children's family. On the other hand, the social health state of the subjects was relatively low scoring 2.585, mainly due to that 80% of them was widows which was resulted by the 6-7 years longer life-expectancy of Korean women. 2. A significant differences in the physical health state scores between different age groups was observed, indicating the rapid ageing process occurring in this age group. The family structure was appeared to be an important factor influencing the physical health state of the female elderlies ; the physical health score of the women with her husband only was higher than that of those living with children's families, and the lowest score was obtained from those living alone. 3. The age was the most important factor determining the mental health state of the subjects, while the religion, educational status, marriage state and family structure did not significantly influenced the mental health state of the aged women. 4. The social health state of the subject was deeply influenced by the marriage state and family structure, showing significantly lower scores with widowers compared to the married couples. Those living with their married spouse only obtained the highest social health score, while those living along showed the lowest score. The parent and grandparentship of those living with their children and the religion, especially Catholic and Protestant, had positive influence on the social health state of the aged women. 5. The mental health state of aged women showed significant correlation with the factors determining the physical health, except for digestive system related ability and sexual ability and the highest extra home ability. 6. The mental health state of aged women showed significant correlation with the factors determining social health, especially with the parent and grandparentship and the family relative's role. From these results, the following recommendations are made. 1. Since the physical, mental and social health states of aged people are deeply influenced by the sex and the average values of the both sex can create misleading figures, the health evaluation of the elderlies should be made separately by sex. 2. Since the health state of aged women is highly influenced by their family structure, the spouse's role and living with married couple only should be emphasized in respect of preventive health care. 3. The social activity programs and grandparentship teaching programs should be prepared in the nursing care program for aged people.

Objective：At the present time in Korea, for a considerable proportion of children and adolescent, delinquent behavior and violence has become as a way of life in their lives and a major social problem issue as well. The contributing factors to this problem were assumed to be the negative interaction between family environment and character of adolescent. The purpose of this study is to search the relationship between these constructs and juvenile delinquency. Method：Data were collected through questionnaire survey over a period of 2 months. Subjects served for this study consisted of 1,863 adolescents including 657 delinquent adolescents and 1,206 student adolescents in Korea, sampled from Korean student population and delinquent adolescent population confined in juvenile corrective institutions, using proportional stratified random sampling method. Their age ranged between 12 and 18 years. Data were analysed by IBM PC using SAS program. Statistical methods employed were Chi-square and principal component analysis. Results：The results of this study were as follows：Inconsistency by parental child rearing patterns tended to affect delinquent behavior among delinquent adolescents. On the other hand, adolescent students were consistently reared by their parent with democratic, flexible, trusting their children and reward-oriented attitudes. In comparison of both parents in the degree of influence on their children, it was revealed that paternal child rearing pattern was more influential on their children’s behaviors than maternal’s. The psychological instability of family, disharmonious parent-child relationships tended to be contributing to delinquent behavior among delinquent adolescents. Especially, It was an interesting finding that student’s mother is the higher employed than delinquent’s mother. However working mother was more prevalent in the student’ adolescents than in student adolescents in previous studies. The delinquent adolescents have more depressive trend, more complaints of psychosomatic symptoms, the higher degree of need frustration, the more maladaptive and antisocial personality pattern than student adolescents. Conclusion：Recently, many studies on association between family factor, character of adolescent and juvenile delinquent behavior have produced relatively consistent results. This study showed that family environment and character trait of adolescent also were linked with delinquent behavior such as smoking, drinking, runaway and physical assaults etc. The results of this survey may provide impetus for future speculation and study of correlation or reciprocal interaction between family factor, character trait of adolescent and delinquent behavior during adolescence and beyond.

The bioaccumulation of 16 United States Environmental Protection Agency (USEPA) priority polycyclic aromatic hydrocarbons (PAHs) and alkylated PAHs in the Manila clam, Ruditapes philippinarum exposed to sediments artificially contaminated by Iranian Heavy Crude Oil was measured and the biota-sediment accumulation factor (BSAF) was estimated through laboratory experiments. The proportion of 16 PAHs accumulated in the tissue of R. philippinarum was only from 3 to 7% of total PAHs. Among 16 PAHs, the concentration of naphthalene was highest in the tissue. Alkylated PAHs were highly accumulated more than 93% of total PAHs. The C3 dibenzothiophene was most highly accumulated. The relative composition of alkylated naphthalenes in the tissue of R. philippinarum was lower than in the sediments. In contrast, those of alkylated compounds of fluorenes, phenanthrenes, dibenzothiophenes were higher in the tissue than the sediments. The BSAF for sum of 16 PAHs was 0.11 to 0.13 g carbon/g lipid and that for alkylated PAHs was 0.05 to 0.06 g carbon/g lipid. Naphthalene showed the highest BSAF value. Alkylated PAHs with the same parent compound, BSAF tended to increase with the number of alkylated branch increased, except for alkylated chrysenes. BSAF of total PAHs lies between that of field-based values, and are also similar to those of other persistent organic pollutants (PCBs, DDTs, HCHs). This study provides the BSAF values of individual alkylated PAHs accumulated in R. philippinarum for the first time and will be used as a basis for further understanding the bioaccumulation of organic contaminants in the marine benthic organisms.

Isotianil is a fungicide which has prevention effects against rice blast disease. In order to register this new pesticide, the series of toxicity data on animal testing were reviewed to evaluate its hazards to consumers and to determine its acceptable daily intake. Isotianil was almost excreted by urine and feces. It has low acute oral toxicity while has no skin toxicity and ocular irritation. Its skin sensitization was evaluated as slight. Genotoxicity of parent compound and metabolite was negligible. Chronic toxicity tests on rats and dogs showed changes of hematology, clinical biochemistry and liver weight. It had no reproductive and teratogenic effects. The estimation of Acceptable Daily Intake(ADI) is based on the lowest no-observed adverse effect level (NOAEL). The lowest NOAEL of 2.83 mg/kg bw/day was found in the twelve-months rats study. The NOAEL was based on increased liver weight and treatment-related effect on clinica chemistry finding at the nest higher dose level of 2.83 mg/kg bw/day. Therefore, it is considered appropriated to apply an uncertainty factor of 100 to the NOAEL 2.83 mg/kg bw/day from the rat study, resulting in an ADI of 0.028 mg/kg bw/day.

This study was surveyed among 1136 respondent of high school girls in seoul from Feb. 6, till Feb. 22, 1992 for the purpose of analysing the smoking of high school girls and its factor. The data was analied by X²-test and Multiple Regression and shows the following. 1. Out of 1,136 respondent, the current smokers were found to be 176, 15.5% and the former smokers were 204, 18.0%. This implies that 23.5% of high school girls seoul have experience smoking. 2. For the first smoking time in both smoking group and former smokers, it shows that the third grade of middle school lead the lists. 36.9% (65) of the smokers and 37.3(75)of former smokers experienced the first smoking at that time. 70.5%(124) of the smoking group have the intention to stop smoking and the first reason of it is health problem, 65.6%(75). 3. For the type of the school the smoking rate rages from 2.7%(7) of literary part in day time to 25.3%(97) of vocational part in evening time and the rate of smoking experience shows from 9.9%(26) literary part in day time to 25.3%(97) of vocational part in evening time. This data show that literary part in day time has the lowst rate while vocational part in eveing time the highest rate. 4. Compared with non smoker group, smoking group and former smoking group spent more money (P<0.001) and felt dissatisfied with school life and didn't have good school records. 5. Smoking group and former smokers have more boy friends than non smoking group and in most cases their boy friend have smoking habits (P<0.001) and it is the same with their gril friend (P<0.001). 6. Compared with non smoker group, smoking group and former smokers lack of their parents' interest (P<0.001). But whether it is strict or free there is little difference among the three group. 7. For smoking group and former smoking group, in most cases their parent, brother and sister tend to smoke and especially their sisters' smoking has much influence on their smoking in comparison with non-smokers. 8. Compared with non-smoker group, smoking group and former smoking group tend to think less of the harm of smoking. In regard with health problem, more smoking group and former smokers think that smoking can relieve the stress (P<0.001), and more non-smokers know that when a pregnant woman smokes, it can cause the lack of supply of Oxygen{P<0.01). 9. Smoking group and former smoking group have more positive attitude towards smoking than non-smokers and tend to agree to their boy and girl friends' smoking(P<0.001).

Purpose:Epilepsy of child may cause high level of psychosocial difficulties for parents including stigmatization and stress and therefore worsen their quality of life (QOL). The purpose of this study was to evaluate the mediating effect of perceived stigma against epilepsy on QOL among parents with epileptic child. Methods:Two hundred and sixty parents of epileptic child recruited from five separated university hospital child neurology clinics specializing in epilepsy completed a demographic questionnaire, a medical questionnaire, a perceived stigma questionnaire and the Ro's Quality of Life Inventory, a popular tool for evaluating QOL of adults in Korea which is composed of 6 domains and 47 questions. Data was analyzed with SPSS 14.0 program using frequency analysis and descriptive analysis and with AMOS 7.0 program using Structural Equation Model (SEM) analysis. Results:The level of parents' QOL was relatively fair. SEM analysis on the quality of life level of parents showed that all variables (especially having religion, the monthly income, employment state, age of child, the leisure time, the perceived stigma level against epilepsy, and seizure frequency) directly affect the quality of life level of parents and that disease-related variables also affect the quality of life level of parents indirectly through the mediating factor (the perceived stigma), where the indirect effect is large with the existence of combined disabilities. The total effect on the quality of life level of parents is large with the existence of combined disabilities, the perceived stigma level, the leisure time, having religion, and the monthly income. Conclusion:The results of this study indicated that many factors including parents' perceived stigma may affect the quality of life of parents with epileptic children directly, and that some disease-related factors may affect indirectly through a mediating factor, the perceived stigma. Multidisciplinary collaboration would be imperative for their welfare.

This study analyzes the effects of the self-esteem on the life satisfaction of 2,040 middle school senior students using the Korean Children and Youth Panel Survey 2012 Data (KCYPS 2012) provided by the National Youth Policy Institute. In the ecological perspectives, this study considers two factors which influence the life satisfaction of the students; one factor is the environmental characteristics like parent intimacy, friend intimacy, teacher intimacy and study adaptation, and the other factor is the individual characteristics. In particular, self-esteem as one of the individual characteristics is divided into two separate categories, positive self and negative self. The two categories are found to have some interaction effects on the life satisfaction at the evaluation level. The effects of the negative self-evaluation on the life satisfaction appear to be different depending on the level of the positive self-evaluation. As the level of the positive self-evaluation becomes higher, the effects of the negative self-evaluation on the life satisfaction decreases. The life satisfaction becomes higher as the level of the negative self-evaluation is lower, and the life satisfaction is not high relatively at the low level of the positive self-evaluation. These results suggest that solving the adolescent's negative self-formation problem can not bring out the positive self-formation and there should be some plans for the positive self-formation more than simply solving the negative self- formation problem in order to improve the life satisfaction.

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.
