The purpose of this study was to investigate emotional intelligence and stress coping styles of adolescents. The study also identified the differences of emotional intelligence and stress coping styles between normal adolescents and juvenile delinquents. The subjects in this study were 447 adolescents included 249 normal adolescents and 198 juvenile delinquents. The major findings as follows: First, there were significant differences on emotional intelligence between normal adolescents and juvenile delinquent. Normal adolescents had higher level of emotional intelligence. However there were no significant differences on stress coping styles except wishful thinking between normal adolescents and juvenile delinquent. Second, there were overall positive correlation between emotional intelligence and stress coping styles. However regulation of emotion showed negative correlation with stress coping styles. The result of Canonical Correlation revealed that emotional facilitation of thinking among five sub-domains of emotional intelligence was the best contributor to predict stress coping styles of adolescents.

The purpose of this study was to determine the differences in internet use motivations and problem behaviors among vocational high school students according to internet addiction and family system type. Five hundred vocational high school students from Daegu took part in the survey. The questionnaire survey consisted of an internet addiction self-assessment scale, a family system type scale, an internet use motivation scale, and a problem behavior scale. The data was analysed using MANOVA and Cronbach a, and the $Scheff\acute{e}$ test was used for post-hoc analysis. The major findings of this study were as follows: First, the study found significant differences in adolescent internet use motivation according to internet addiction. Adolescents in the high dangerous user group showed higher communicative, experiential, and addictive motivations than adolescents in potentially dangerous and normal user groups. Also, there were no significant differences in informative motivation according to internet addiction. Regardless of internet addiction, adolescents tend to use the internet to search for information and to solve problems. Second, there were significant differences in adolescents' problem behaviors according to internet addiction. More specifically, adolescents who were in the high dangerous user group displayed more problem behaviors toward their body, family, school, and society than adolescents in the potentially dangerous and the normal user groups. Third, an adolescent's family system type significantly influenced his/her internet use motivation. Adolescents from an extreme family showed higher communicative and addictive motivations than adolescents from middle and balanced families. Fourth, there were significant differences in the problem behaviors of adolescents according to family system types. Adolescents from an extreme family showed more problem behaviors toward their body, family, school, and society than adolescents from middle and balanced families.

This study of elderly in-patient subjects' expected level of care given by family members and nurses is intended to provide foundational information for use by nurses is attending to elderly patients. The objects of the study were elderly in-patients over the age of 65 hospitalized at two General hospitals in Chonju: 102 subjects filled out the 60 question survey between December 16 and 24. 1996. The analysis process was conducted using SPSS producing percentage. mean and standard deviation. maximum and minimum values. t-test, ANOVA. and so on. The results are as follows: 1. From the general results of the survey. one can observe that statistically significant differences appeared in various levels of education of the subjects: no education(2.98). primary school completed(2.91). middle school or higher completed(2.77). As shown. the lower level of education correlates with higher care-giving expectation. 2. On a scale of 1(minimum) to 4(maximum). the mean levels of care expected by elderly inpatients from their families is 2.93. with a standard deviation of 0.28. The level of psychological care expected(mean 3.02. standard deviation 0.31) is higher than the level of care expected(mean 2.83. standard deviation 0.34). 3. The level of care expected among those of different levels of dependency for daily living (differentiated as dependent. partially dependent. independent) was highest among the partially dependent(mean 2.98. standard deviation 0.17). but the results were not statistically significant. 4. Elderly in-patients with high levels of emotive interaction with their families expected relatively high levels of physical care. while the highest levels of socio-psychological care were expected from those who reported normal levels of emotive interaction with their families. However. We can see that low levels of care are expected from those reporting low levels of emotive interaction with their families. Overall. the differences in the level of care expected between those reporting different levels of emotive interaction with their families was not shown to be statistically significant.

Purpose: Growing evidence indicates that adolescents from multicultural families are more vulnerable to drug use than those from non-multicultural families. This study aimed to compare the factors associated with the habitual drug use among adolescents from multicultural and non-multicultural families. Methods: A descriptive cross-sectional design was employed. Data were obtained from the 14~15th (2018~2019) Korea Youth Risk Behavior Web-based Survey. Overall, 91,443 multicultural (n=1,725) and non-multicultural adolescents (n=89,718) were included. Data were analyzed using descriptive statistics, univariate analysis, and logistic regression analysis. Results: The multicultural adolescents engaged in more habitual drug use than did non-multicultural adolescents. In both groups, those who currently drank, experienced violent victimization, had sexual experiences, and did not live with their family were at greater risk of engaging in habitual drug use. The odds ratios of these factors were higher in multicultural adolescents than in non-multicultural adolescents. In non-multicultural adolescents, those who were boys, had experienced depression and suicidal ideation, perceived their body image as normal, overweight, or obese, and had poor subjective health status were at greater risk of engaging in habitual drug use. Conclusion: These results highlight the need to develop customized strategies for adolescents from both multicultural and non-multicultural families to reduce and prevent their habitual drug use.

In this paper, we consider some normality criteria concerning multiple values. Let $\mathcal{F}$ be a family of meromorphic functions defined in a domain D. Let k be a positive integer and ${\psi}(z){\not\equiv}0$, ${\infty}$ be a meromorphic function in D. If, for each $f{\in}\mathcal{F}$ and $z{\in}D$, (1) $f(z){\neq}0$, and all of whose poles are multiple; (2) all zeros of $f^{(k)}(z)-{\psi}(z)$ have multiplicities at least k + 3 in D; (3) all poles of ${\psi}(z)$ have multiplicities at most k in D, then $\mathcal{F}$ is normal in D.

In order to estimate a parameter $(\alpha,\beta^r), r\epsilonN$, in a distribution belonging to a location-scale family we usually use best invariant estimator (BIE) and best unbiased estimator (BUE). But in some conditions Ryu (1996) showed that BIE is better than BUE. In this paper we calculate risks of BIE and BUE in a normal and an exponential distribution respectively and calculate a percentage risk improvement exponential distribution respectively and calculate a percentage risk improvement (PRI). We find the sample size n which make no significant differences between BIE and BUE in a normal distribution. And we show that BIE is always significantly better than BUE in an exponential distribution. Also simulation in a normal distribution is given to convince us of our result.

In this paper we study the problem of normal families of meromorphic functions concerning shared values. Let F be a family of meromorphic functions in the plane domain $D{\subseteq}{\mathbb{C}}$ and n, k be two positive integers such that $n{\geq}k+1$, and let a, b be two finite complex constants such that $a{\neq}0$. Suppose that (1) $f+a(f^{(k)})^n$ and $g+a(g^{(k)})^n$ share b in D for every pair of functions f, $g{\in}F$; (2) All zeros of f have multiplicity at least k + 2 and all poles of f have multiplicity at least 2 for each $f{\in}F$ in D; (3) Zeros of $f^{(k)}(z)$ are not the b points of f(z) for each $f{\in}F$ in D. Then F is normal in D. And some examples are provided to show the result is sharp.

Mungbean plants generally have a relatively close canopy, thus a large amount of self-shading can reduce yield due to poor light penetration. Modification of leaflet type can affect leaf canopy and could alter seed yield. Two multiple leaflet mutants were obtained from gamma-ray irradiation and used to study the mode of inheritance related to leaflet types and to evaluate their agronomic features. The cross between large-heptafoliate leaflet with small-pentafoliate leaflet mutants produce all $F_1$ plants with normal trifoliate leaflets. The $F_2$ plants segregated in leaflet size and leaflet number into a 9:3:3:1 ratio of large-trifoliate: large-heptafoliate: small-pentafoliate: small-heptafoliate plants, suggesting that independent loci control leaflet size and leaflet number. Regarding leaflet number, the $F_2$ population can be classified into normal-trifoliate, small-pentafoliate, large-heptafoliate, and small-heptafoliate at the dihybrid ratio of 9:3:3:1. The gene symbols $N_1,n_1$ and $N_2,n_2$ are proposed to represent leaflet number. Since no plant was found with large-pentafoliate leaflets, we hypothesize that the $N_2$ allele expresses pleiotropic effect on both leaflet number and leaflet size. Another possibility is that an additional locus with S and s alleles controls leaflet size and S is tightly linked with $N_2$. The effect of multifoliate leaflet on yield and yield components was evaluated in four mungbean families each with four leaflet isolines under three environments. Averaging across the families and environments, the normal-trifoliate and large-heptafoliate lines gave higher yield than small pentafoliate and heptafoliate ones. These two large leaflet lines also had higher leaf area per plant than the other multifoliate lines. Therefore, the mungbean lines with a greater leaf area, which were likely to intercept more sunlight, gave greater yield. Three AFLP markers that were found to be linked to number of leaflets per leaf, corresponded to the N1 allele of the smallpentafoliate parent.

Purpose of this study was to investigate intake pattern of sodium in the family members of normal and stomach cancer patients, excluding patients themselves. Every food samples that they consumed for 3 days, drinking water, hot pepper paste, soybean paste and soy sauce from the each family were collected for Na analysis. Three days of morning urine from the each subjects was collected for determination of urinary Na excretion. Sodium contents of hot pepper paste, pickles, soups and meats in stomach cancer families were significantly higher than those in normal families. However, urinary sodium excretion between the two groups was not different. This suggests that sodium metabolism in human may be altered with a long-term intake of sodium=rich foods.

Purpose: The purpose of this study was to explore the experiences of parenting from the parents of children with ADHD and to develop a grounded theory about their experiences. Method: This study was a qualitative research study that used a grounded theory to understand and discuss the parenting experiences of parents of children with ADHD in a greater depth. Grounded data was collected through an in-depth interview from twelve participants with ADHD children. The data was analyzed using the grounded theory method. Results: 'Approaching the normal' emerged as the core phenomenone. Parenting experiences for parents of children with ADHD referred to a process of bringing the children, back on track of normal growth development, and their functioning in the family at a normal level and establishing a new normalcy. The process of approaching the normal involved a basic social-psychological process, such as 'living a day in hell', 'accepting', 'confronting the conflicts', 'lowering expectations', and 'making a new normalcy'. Conclusion: The outcomes of this study, which observed the parenting process of parents of children with ADHD, could enhance nurses' understanding of ADHD and help nurses become major mental health service providers for the mental health of children with ADHD and their families.
