This study was conducted to inquire about the view on childrearing of university women for the purpose of building up the positive parent- child relationship and setting up preliminary parenting education program. The subjects were 137 university women who were freshmen to junior in one women's university in Seoul. Using the self-report questionnaire, data were collected from December in 1998 to March in 1999 and the contents which subjects wrote down were categorized by content analysis method. The results were as followed: 1. The age range of subjects were 20-22 years and main rearer was her mother(71.5%) 2. The view of subjects were revealed by 374 statements and then tied together 34 themes: 'exemplary parent model as a guider'(8.6%), 'determination for oneself' (8.0%), 'expression of love'(6.2%), 'humanity education'(4.8%), 'carrot and stick'(4.5%), 'respect of personality'(4.3%), 'sound living habit'(4.1%), 'conversation'(3.7%), 'regulation of greediness' (3.7%), 'supply of live experience'(3.7%), 'supply of broad and substantial vision'(3.5%), 'free choice'(3.5%), 'broad-mindedness'(3.5%), 'consideration'(3.0%), 'doing together'(3.0%), 'propriety education' (2.4%), 'pursuit of naturalness'(2.4%), 'looking for one's life'(2.4%), 'confidence'(2.1%), 'rearing by oneself'(2.1%), 'encouragement'(2.1%), 'cultivation of right sexual senses'(2.1%), 'desirable home environment'(1.9%), 'doing one's best'(1.9%), 'understanding'(1.6%), 'psychological intimacy'(1.6%), 'treat fair'(1.6%), 'pursuit of physical, psychological health' (1.6%), 'concerning'(1.3%), 'religious life'(1.3%), 'respect of individuality'(1.3%), 'cooperation' (1.1%), 'often-minded family'(0.8%), 'positive attitude'(0.8%). 34 themes were categorized by 12 categories once more: 'mature parenthood'(15.5%), 'acceptance' (11.5%), 'autonomy'(11.5%), 'pursuit of healthy life style'(9.4%), 'eagerness'(9.1%), 'making efforts'(8.8%), 'education'(8.8%), 'emotional bonding' (7.8%), 'respect'(7.2%), 'corporal punishment' (4.5%), 'supporting'(3.2%), 'composition of environment'(2.7%). In conclusion, we could expect that university women had a democratic view on childrearing with love and autonomy for a base. So we need to offer them nursing implementations such as preliminary parenting programs and parenting consulting in order to promote positive and interactional parent-child relationship by strengthening their desirable view on childrearing.

This study attempts to examine the relationships between the major market-based media and the government after closing military regime era, 1961-1987. After the military regime was collapsed, while the mass media in Korea obtained independence and autonomy from government, they have been confronted with the terrible competition not so much comparatively as before. The watchdog role in the traditional liberalism, which is regarded as normative relationship between the media and the government would be transformed in accordance with the market condition and the maturity of democracy. Thus, the watchdog metaphor has been variously deviated in rower-centered society; lap dog, guard dog, attack dog. liberalists argue that the primary democratic role of the media is to art as a public watchdog overseeing the state. Social democrats, however, criticize them as simplistic conception which could be only applied to the government. They argue that the media should be seen as a source of redress against the abuse of all forms of power over others; the home, the economy, and the civil society. The lap dog view is that the media is overwhelmingly dependent on the established power structure contrary to the watchdog. While the guard dog perspective is a means to preserve the power structure alarming with playing 'conflict role', the attack do8 aims to the private interest of the media in intruding into the politics. The attack dog perspective by T. Patterson could be composed of the interpretive style of report, the game schema report over the policy schema in the election, and the negativism against politics and government. The market-dominant press has been likely to transform from lap-guard dog into attack-guard dog. In Roh Tae Woo government(1988-1992), while the press was a lessened lap-guard dog before three parties merger in 1990, after merger the press had been transformed as the reinforced lap-guard dog because this merger entailed joint, party-to-party negotiations, and the formation of the new party preceded by dissolution of the ruling blot. In the early stage of Kim Young Sam government(1993-1997), the press has kept in pace with the reform movement drive-forced by the government. However, the press withdrew the support of Kim's reform in reaching the level of threat to ruling bloc. The press coalesced only circumstantially with government and was interested in preserving some margin of independence. The failure of Kim's reform proved the political muscle of the press in post-autho-ritarianism. In the middle stage of Kim Dae Jung government (1998-) that resulted in the shift of power structure as once-opposition party leader, the stress has been a manifested attack-guard dog owing to the anti-cold war policy, the realignment policy of power, and the minority-base of Kim's government. The press has endeavored to hold political communication within limits relatively less threatening to the established order.

One of the important tasks for new parents, especially mothers, is to establish warm, mutually affirming interpersonal relationships with the new baby in the family, with the purpose of promoting the health development of the child and the well-being of the whole family. Nurses assess the quality of the behavioral characteristics of the maternal-infant interaction. The purpose of this longitudinal descriptive correlational study is to investigate the changes of the mother - infant interactions from postpartum 1 day to postpartum 8weeks of the transition to parenthood. The aim was to contribute to the development of theoretical under standing on which to base care toward promoting the quality of maternal - infant interaction. Data were collect ed directly by the investigator and at rained from Jul, 1, 1990 to Jun 8, 1991, Subjects were a random sample of 44 mothers, 44 who had a normal delivery (but with out other perinatal complications) at four general hospitals in Seoul. Instruments used were the Stainton Parent-infant Interaction Scale (1981). The first observations were made in the delivery room, followed by day 1, day 2, day 3 and 2 weeks, 4 weeks, 6 weeks and 8 weeks after, birth, for a total of 8 contacts. Observations in the hospital were made during the hour prior to scheduled feedings. The infant was placed beside the mother. Later contacts were made at home. Data analysis was don by computer using as SPSS program and included, Paired t-test, t-test and Pearson Correlation coefficient ; the results were as follows. 1. The daily maternal-infant interaction score for the initial contact ofter birth to 8 weeks postpartum had the lowest average score 5.21 and the highest 8.02(in a range of 0-10). This subject group of mothers needed Extra nursing supporting to promote their maternal-infant interaction. 2. The daily scores for the maternal-infant interaction tended to rise, showing a gradual improvement over the period of eight weeks. However, there were significantly different increases in maternal-infant interaction only from the first to second day (p=0.000) and from the fourth to sixth weeks ofter birth.(p=0.000) 3. When the seven items of maternal-infant interaction were evaluated items of maternal-infant inter action were evaluated separately, "Care taking for the baby" had the highest average score, 1.60(in a range of 0-2) and "Speaks to baby" the lowest, 0.8. All items, suggested the subjects' need of nursing intervention to promote maternal-infant interaction 4. There were positive correlations between certain general characteristics, namely, both a higher economic status (p=0.027) and breast feeding (p=0.021) and maternal-infant interaction.

The purpose of this study is to provide the information of the aged olds for which basic data are almost no available. The subjects were divided on the base of age 75. The elderly under 75 were named 'the young olds' and over 75 were 'the aged olds'. The aim of this research is to promote health and to improve nutrition, and the survey was made for health promotion behaviors, habits against health risk, dietary management status and diet intake. And it was conducted by 24 hr-recall method and analyzed by nutrients intake. 242 subjects were collected in 12 cities or counties in Gyeonggi Province and 20 elderly people (10 male and 10 female) were selected out of 1 village in each district. Questionnaire about health behavior and dietary management was carried out by interview method through regional home extension workers. Statistical analyses were made by SAS (version 8.1) and Chi-square tests and General Linear Models were used. Out of the subjects the aged olds over 75 was 31.9%, elementary school educated (93.5%), with spouse (40.3%), with adult children(28.6%), monthly living cost of 500-1,000 thousand won(40.3%). Mean age was 78.82 years compared with 69.75 years of the young olds. 46.8% of the aged olds used monthly pocket money over 1000 won and it was lower than 63.3% of the young olds. Only half of the aged olds had regular exercise of walking (77.8%) or with athletic equipment (17.8%). However, the young olds did more frequent walking (82.1 %) and less exercise with athletic equipment (4.8 %), which was significantly different. Kinds of disease were different with the young or the aged olds, as more proportion of cardiovascular disease(37.9%) for the young olds and joint lumbago neuralgia(41.6%) for the aged olds. Dietary management was good (3 meals per day: 93.4%, fixed mealtime: 72.4%, and regular amount: 79.9%). But there was significant difference in side dish varieties and kinds of snacks; for the aged olds only 8% had over 5 sorts (compared with 18.8% of the young olds) and the kinds of snacks were cookie, candy, juice, carbonated beverage for the aged olds (compared with noodle, milk, soybean-milk for young olds). The ratio of nutrients intake (energy, riboflavin and niacin) with RDA was significantly higher for the aged olds than that of the young olds. The surveyed subjects had no difficulties in Activities of Daily Living (ADL), but some of the aged olds had difficulties in Instrumental Activities of Daily Living (IADL) like housekeeping, using transportation, going shopping and making phone calls. These results suggest that low quality of life is linked with low economic status of the rural elderly and congregate meal at village hall would be required because of the lack of side dishes variety for the aged olds. And nutrition education program about good snacks and exercise practice would be needed for the aged olds. By operating nutrition education program the aged olds would enjoy better quality life maintaining or ameliorating IADL abilities.

The aims of this study are to investigate the impact of the experience of exposure to domestic violence(witnessed interparental conjugal violence and child abuse) on mental health among college students, and to explore whether social support acts as a moderator between domestic violence and mental health. Through this process, I intended to provide a reference base to suggest substantial interventions for family welfare by helping students to overcome negative domestic violence exposure experiences and adapt as healthy members of society. To achieve this goal, the study established a conceptual framework by considering the mental health of adolescents with domestic-violence exposure experience as a dependent variable, domestic violence exposure experience (witnessed interparental conjugal violence and child abuse) as an independent variable, and social support as a moderator of the relationship between these two variables. The subjects composed 747 college students in 8 colleges in Seoul. The main summary of this study is as follows: First, according to the analysis of domestic-violence exposure experience, all the subjects of this study had substantial experience of violence at home and witnessed interparental conjugal violence. These students scored 3.83 points in social support, higher than the median of 3, implying that these students had a higher awareness of social support. Moreover, their mental health score was 3.50 points, which is higher than the median of 3, indicating a somewhat positive tendency toward mental health. Second, to explore the moderating effects of social support between child violence experience and mental health, gender, age, financial status, academic-performance, child abuse and social support were input in the first step, and then buffering effects were examined by entering an interaction term to the first step in the second step. There was a significant interaction between social support and mental health. Therefore, social support was identified as having moderating effects on the relationship between child violence and mental health. Third, the analysis of moderating effects of social support between witnessed interparental conjugal violence and mental health revealed that social support had a positive influence on mental health in the first step. By contrast, the interaction term of witnessed interparental conjugal violence and social support showed no significance, indicating no moderating effect of social support in the second step. To sum up, social support served as a moderator for mental health among college students with child abuse experience, but had no moderating effect on witnessed interparental conjugal violence experience.

본 연구는 OLS모형을 적용하여 주택보유기간에 영향을 미치는 결정요인을 추정한 후 SVM, Decision Tree, Random Forest, Gradient Boosting, XGBoost, LightGBM을 통해 각 모형별 예측력을 비교하였다. 예측력이 가장 높은 모델을 기반모델 삼아 앙상블 모형 중 하나인 Stacking모형을 적용하여 더욱 예측력이 높은 모형을 구축하여 주택시장의 주택거래량을 파악할 수 있다는 점에 선행 연구와의 차이가 있다. OLS분석 결과 매도이익, 주택가격, 가구원 수, 거주주택형태(단독주택, 아파트)이 주택보유기간에 영향을 미치는 것으로 나타났으며, RMSE를 기준삼아 각 머신러닝 모형과 예측력 비교한 결과 머신러닝 모델의 예측력이 더 높은 것으로 나타났다. 이후, 영향을 미치는 변수로 데이터를 재구축한 후 각 머신러닝을 적용하여 예측력을 비교하였으며, 분석 결과 Random Forest의 예측력이 가장 우수한 것으로 나타났다. 또한 예측력이 가장 높은 Random Forest, Decision Tree, Gradient Boosting, XGBoost모형을 개별모형으로 적용하고, Linear, Ridge, Lasso모형을 메타모델로 하여 Stacking 모형을 구축하였다. 분석 결과, Ridge모형일 때 RMSE값이 0.5181으로 가장 낮게 나타나 예측력이 가장 높은 모델을 구축하였다.
