As teenagers' Internet use increases and Internet takes an important part in their everyday lives, many people become concerned with Internet addiction. In this study, I attempt to analyze the current status of teenagers' Internet addiction using an evaluation tool developed for students, and to compare elementary students' Internet addiction level with secondary students. Also I analyze factors affecting Internet addiction. For the analysis, 18 variables are selected from the areas such as demographic background, the experience of Internet use, family-related traits and social activities. A survey was conducted to 1,155 elementary students and 1,822 secondary students selected from nationwide schools. The main finding of this study is that among the elementary students 5.0% of the sample students are in the stage of serious addiction, and 19.7% in the stage of early addiction. In addition, the level of elementary students' Internet addiction is significantly higher than the level of secondary students. Also, the degree of elementary students' Internet addiction is significantly affected by some factors such as gender, surfing time, surfing purpose, satisfaction with parental relationship, parents' interference in Internet use, conversation frequency among family members, and satisfaction with school life.

This study was conducted to identify factors influencing depression symptoms among college students. To accomplish this, a self-administered questionnaire was distributed to 546 college students from October 1st to November 30th, 2015. Univariate analysis, logistic regression, and multivariate regression analysis between variables were then conducted using depression symptoms as the dependent variable and other relevant factors as independent variables. The level of depression among the subjects differed significantly according to personal attributes, family life and school life characteristics, as well as health related behavioral characteristics. The risk of depression was significantly higher in the lower group than the higher group of family and friends social support, the lower group than the higher group of self-esteem, the lower group than the higher group of locus of control, and in the high risk stress group than the normal stress group. Factors influencing depression symptoms included religion, social support from family, social support from friends, interpersonal dependency, locus of control, and stress were identified as significant variables, indicating that depression among college students is related to diverse elements including sociodemographic characteristics, social support from family/friends, interpersonal dependency, locus of control, and stress. Depression symptoms significantly increased when social support from family or friends, low psychological behavior characteristics are low, and when stress is high. Thus, it is necessary to understand factors related to depression and reduce them to decrease depression levels of college students.

The purpose of this study was to investigate the relationship between alcohol use and drinking problems among college students. Data were collected by structured questionnaires from 400 college students by convenient sampling methods from September 26 to October 14, 2011. Data were analyzed by SPSS/WIN 15.0 program. The results were as follows: According to the Alcohol Use Disorder Identification Test (AUDIT), subjects were classified into four groups such as 40.2% of no problem, 36.7% of drinking problem, 6.8% of high risk drinking problem and 16.3% of alcohol dependence. The alcohol use and drinking problems were significant difference for gender, age, type of residence, age of first drinking, cause of drinking, frequency and amount of drinking. The alcohol use was correlated with drinking problems: social function impairment(r=.601, p<.01), behavior problem(r=.579, p<.01), family and interpersonal impairment(r=.637, p<.01). The influencing factors of drinking problems were alcohol use(${\beta}$=.640, p=.000). This study concludes that it is necessary to establish alcohol use policies on campus and develop temperance education program to reduce alcohol consumption and drinking problems.

BIDANI is the action-research program. BIDANI aims to be truly a people's program embodying their own activities and aspiration. BIDANI sees an integrated development approach at the community level with participatory services embodied in a Barangay Integrated Development Plan(BIDP) designed by the people themselves. Community situational analysis is conducted by the people to identify the priority problems and potential resources in the barangay. Participatory planning, using the “bottom up” apporach, is exercised to formulate a BIDP. Proper motivation and advocacy encourage barangay people's participation. Accessibility and efficiency in the use of various services and resources of government and private agencies increase. Family groups who are at high-risk to malnutrition become aware of the importance of nutrition through their participation in development program activities. Integration of political and socio-economic concerns at the lowest level is operationalized. Implementation and sustainability of the program on a wider scale from a model project to a model program is facilitated through institutionalization at the municipal/city level with the mayor as the project director. “Top to bottom” planning through a City/Municipal Integrated Development Program(C/MIDP) interacts with “bottom up” planning at the barangay level. The establishment of a local Training School for Barangay Development(TSBD) in each municipality and city for continuing education of indigenous village workers and barangay people is a vital component for success and viability. The role of non-political entities such as academic institutions and non-government organizations, as catalytic agents of development, is stressed.

Using data collected from Korean mothers (N＝429) with preschool children (aged 3 to 5 years) in 12 day care centers in Seoul, this study aims to empirically demonstrate the different pathways acute and chronic stress affect parenting efficacy of mothers according to the income group to which they belong. Analytic results show mothers in the low-income group show higher levels of depressive symptoms than mothers in the middle-income group, and the former also show more frequent and higher levels of acute and chronic stress than the latter. The mediation model results show that acute stress and chronic stress did not directly affect parenting efficacy, but rather indirectly affect parenting efficacy through maternal depressive symptoms. Acute stress and chronic stress are both significant factors affecting depressive symptoms with chronic stress exerting greater influence. When the total effect was analyzed, chronic stress has a greater effect on parenting efficacy than acute stress. The effect of chronic stress on maternal depressive symptoms is greater on low-income mothers than middle-income mothers, while the effect of acute stress on maternal depressive symptoms and the effect of those symptoms on parenting efficacy are greater on middle class families than low-income families. In order to maximize effective parenting in high-risk situations, the psychological welfare of mothers needs to be protected from the environmental difficulties they face. Based on the results, policies to support women and parents at the national and social levels are discussed.

Purpose : Vesicoureteral reflux(VUR) is known to be the main cause of childhood hypertension and renal failure. Knowing its familial occurrence, we determined the incidence of VUR and renal scar in asymptomatic siblings of Korean patients with primary VUR Methods : A total of 50 siblings from 37 index patients were included. Voiding cystourethro-graphy(VCUG) and renal scintigraphy using $^{99m}Tc-DMSA$ were peformed in these siblings from June, 1994 to May, 2001, Index patients were classified into two groups according to the presence of VUR in their siblings, and the clinical factors of the index patients such as age, sex, grade of reflux and renal cortical defect were compared between the groups. Results : Among the 50 siblings, VUR were found in 8(16%) and renal cortical defects were detected in 8(16%) siblings respectively. The incidence of renal cortical defects was 87.5%(7 out of 8) in the VUR(+) siblings. There was a case of VUR(-) cortical defect in one sibling, presumed as a scar from an old VUR. There was no relationship among age, sex, grade of reflux and renal cortical defect of the index patient to the presence of VUR in siblings. Conclusion : This study confirmed a significant incidence of VUR(16%) and renal cortical defects(16%) in the asymptomatic siblings of patients with primary VUR in Korea. It Is resonable to recommend screening studies to the siblings of patients with VUR for the early detection and prevention of probable reflux nephropathy.

Purpose: The characteristics of hospitalized patients in neonatal intensive care units (NICUs), including hospitalization costs (HC) and National Health Insurance (NHI) status were studied. Methods: We gathered the following data from 7 hospitals in Korea during 2006: the distribution of patients according to birth weight (BW), and the duration of the hospital stay according to BW and He. Results: The patients who were admitted to the NICU consisted of high-risk neonates, including low birth weight or premature neonates, which comprised 50% of all neonates admitted to the NICU. The duration of hospitalization was 75-90 days for neonates with BW <1,000 g, 45-60 days for neonates with BW between 1,000 and 1,499 g, and approximately 15 days for neonates with BW between 2,000 and 2,499 g. The portion of the HC covered by the NHI was 77.1%, 22.9% of the total HC was not covered by the NHI (19.5% was included in the list, but not covered by the NHI and 3.4% was not listed, but covered by the NHI). The average total HC per person was 4,360,000 won, and the HC covered and not covered by the NHI were 3,677,000 won and 1,007,000 won, respectively. The mean HC were as follows; 35,000,000 won for a BW <500 g, 18,000,000 won for a BW between 500 and 999 g, 16,000,000 won for a BW between 1,000 and 1,499 g, and 4,200,000 won for a BW between 1,500 and 1,999 g. Conclusion: Not only premature, but also ill neonates were under the care of the NICU. The HC increased as the BW decreased and the hospitalization period increased. The proportion of the patient's financial burden is >25% of the total He. For this matter, additional NHI is needed.

This study was aimed to provide the basic data for the development of effective educational program by reflecting the opinions of the visiting health service workers. The subjects were 144 visiting health service workers in Gwangju and Jeollanam-do area who responded the mail questionnaire. The data were collected from June to July, 2001 using questionnaire composed of the education need, knowledge by subjective appraisal, and experience of education. The major findings of this study were as follows: 1. The number of respondents who received at least one education within recent three years were 43(29.9%) at the central level, 57(39.6%) at the provincial level and 53(36.8%) at the district level. The satisfaction with education was higher at the central level than at the provincial and district level. 2. Knowledges by subjective appraisal on the 'chronic degenerative diseases management' and 'health promotion' was relatively high. while that of 'rehabilitation' was low. 3. The knowledge by subjective appraisal of visiting health service was related with experience of education and license status. The knowledge was higher in registered nurses than in nurse aids. The curricula related to increased level of knowledge of visting health service workers were 'elderly health care', 'rehabilitation' and 'psychiatric-mental health nursing' educations at the central level 'continuing education for the community health practioners' and 'psychiatric-mental health education' at the provincial level and 'elderly health care', 'rehabilitation' 'psychiatric-mental health' and 'acute diseases control' educations at the district level. 4. The respondents preferred elderly health management as the contents of education, officer group education as the method of education, province(30.4%) as the main body of education, exercise and practice as the form of education, 2-3 times per year as the frequency of education, and 3-5days as the period of education. The findings of this study could suggest that future education program should be planned to increae the knowledge level of visiting health service workers by reflecting their educational need.

Purpose : We studied the prevalence of snoring and its association with diseases, obesity and environmental factors, as well as sleep disturbance arising from snoring, in school-aged children. Methods : The survey was performed by a special questionnaire on 1,707 children at elementary schools from 1 to 30 July 2001 in Gwangju City. The prevalence of snoring, associated factors, and sleep disturbance were evaluated. Results : 266(16.5%) of the children snored at least once a week. 73(4.3%) of the children snored almost every day. Regarding the associated factors of snoring : There was a statistically significant difference between snoring and nonsnoring groups due to gender, obesity, sinusitis, tonsillar hypertrophy, bronchial asthma and allergic rhinitis. Of them, male gender, tonsillar hypertrophy, and obesity were significant risk factors for development of snoring. Especially, the odds ratio increased to 1.048(CI, 1.004-1.659), 1.748(CI, 1.175-2.599), and 2.266(CI, 1.300-3.950) in children with an obesity index of 20-29%, 30-49%, ${\geq}50%$, respectively. There was a statistically significant association of snoring with decreased sleep duration, sleep talking, and drowsiness during the day as a result of sleep disturbance. Conclusion : 16.5% of school-aged children snored at least once a week. The association of snoring with tonsillar hypertrophy, obesity and gender as risk factors was demonstrated in this study.

Objectives: Insomnia is not only the most common sleep-related disorder, but also is one of the most important. Knowledge of the comorbidities of insomnia is essential for proper treatment including pharmacological and non-pharmacological methods to prevent disease chronification. This study aimed to determine sleep clinic patients' knowledge of insomnia. Methods: This study recruited 44 patients (24 males and 20 females; mean age $54.11{\pm}16.30years$) from the sleep clinic at National Center for Mental Health. All subjects were asked to complete a self-report questionnaire about their reasons for visiting a sleep clinic and about their knowledge of treatment and comorbidities of insomnia. Results: The reasons for visiting the sleep clinic were insomnia symptoms of daytime sleepiness, irregular sleeping time, nightmares, snoring, and sleep apnea, in that order. Of the responders, 72.7% had a comorbidity of insomnia, and 22.7% showed high-risk alcohol use. In addition, 70.5% of responders chose pharmacological treatment of insomnia as the first option and reported collection of information about treatment of insomnia mainly from the internet and medical staff. More than half (52.3%) of the respondents reported that they had never heard about non-pharmacological treatments of insomnia such as cognitive behavioral treatment (CBT-I) or light therapy. The response rate about comorbidities of varied, with 75% of responders reporting knowledge of the relation between insomnia and depression, but only 38.6% stating awareness of the relation between insomnia and alcohol use disorder. Of the total responders, 68.2% were worried about hypnotics for insomnia treatment, and 70% were concerned about drug dependence. Conclusion: This study showed that patients at a sleep clinic had limited knowledge about insomnia. It is necessary to develop standardized insomnia treatment guidelines and educational handbooks for those suffering from insomnia. In addition, evaluation of alcohol use disorders is essential in the initial assessment of sleep disorders.
