Objectives： The rate of adolescent smoking is important because lead to adult smoking. And early onset of smoking is associated with chronic disease in adult life. The purpose of this study is to describe the smoking status of adolescents and identify the risk factors for smoking in each school. Methods： We selected the participant schools that are located in Yang-cheon Gu, Seoul, Korea, considering the social economic status. The subjects were included 719elementary school students,1,251 middle school students and 1,513 high school students. Self-reported questionnaires were administrated between December 16 and December 24 , 2002. Students were informed in writing that the survey was voluntary. The response rate was 98.7, 81.1 and 95.4 in elementary, middle, and high school, respectively. Results： The results of this study were as follows： 1) Students who have attempted to smoke were 8.8% in elementary school, 29.3% in middle school and 35.0% in high school. 2) The current smokers were 2.0%, 7.9% and 11.5% in elementary, middle and high school, respectively. 3) In elementary school, smoking of mends and physical health were significantly predicted the attempt to smoke. Stress, smoking of mends, alcohol, and binge drinking were associated with the attempt to smoke of middle school students. In high school, the attempt to smoke was related to gender, maternal education, depression, school performance, smoking of brothers, smoking of mends, alcohol, and binge drinking. 4) Current smoking was associated with smoking of mends and binge drinking in middle school and gender, school performance, smoking of brothers, smoking of mends, alcohol, and binge drinking in high school in multiple logistic regression. Conclusion： There is a need for health education and specific strategies to help adolescents prevent from smoking. Smoking prevention programs which include risk-taking behavior such as alcohol, method of copying with stress, and supporting environment were required.

Purpose: This study was conducted to develop a couple-centered antenatal education program and to test the program's feasibility. Methods: With a preliminary-experimental study design, 33 pregnant couples who were expecting their first child participated in this study. The program consisted of four sessions (1 hour/session/week) of education and counseling. Data were collected before and after the intervention from September 2018 to April 2019 at a women's hospital in Daejeon, Korea, with demographic data forms, the Edinburgh Postnatal Depression Scale, Perceived Stress Scale, Maternal-Fetal Attachment Scale, Korean Newborn Care Confidence Scale, Wijma Delivery Expectancy/Experience Questionnaire, and Dyadic Adjustment Scale-10. Results: The pregnant women and their husbands were on average 32.30±3.10 and 33.21±6.25 years old, respectively. The mean marriage duration was 2.34±1.63 years, the gestational age was 31.30±2.66 weeks, and 78.8% of the couples had a planned pregnancy. After the program, both the pregnant women and their husbands showed significant improvements in attachment to the fetus and confidence in providing infant care. Prenatal depression, prenatal stress, and fear of childbirth in pregnant women significantly decreased after completing the program. However, the dyadic adjustment score did not change significantly either in the pregnant women or their husbands. Conclusion: A couple-centered antenatal education program seems to be effective for couples adjusting to parenthood, but further studies should explore ways to have a positive impact on couples' relationships.

Purpose: The purpose of this study was to review the literature on paternity leave and family health over the last 10 years. Methods: Nine studies that met the criteria were selected from sixty-four studies. General characteristics, study design, and major findings about paternity leave were analyzed using an established analysis framework. Results: From the integrative review, paternity leave was found to affect the health of fathers, mothers, and children, as well as family health and gender equality. The father's paternity leave resulted in an increase in mothers' breast feeding rate, a decrease in maternal depression, a reduction in parenting stress, a reduction in all-cause mortality of men, feelings of instinctive paternal love, increased parenting, skills, and positive parent-child relationships. It was interpreted that paternity leave had a positive effect on the mental and physical health of individual members of the family. Conclusion: This study provides the basic data on the health effects of father's parental leave on the family system in a holistic view. In addition, this study proposes the direction of paternity leave and family health research and policy needs.

This study was conducted to examine how Korean women mange energy metabolism during lactation. Eighteen women recruited were healthy, had normal pregnancies and were required to breast-feed their babies exclusively for at least 12wks. During the study period, all subjects were visited and interviewed five times : 3d, 9d, 4wk, 8wk, and 12wk lactation. Body composition variables were analyzed by a bioelectrical impedance method, energy intakes were assessed by using the inventory-weighing method, energy expenditure were determined by recording daily activities, and milk energy output was investigated from the amount of milk production and the gross energy content of milk. The subjects consumed less energy than current recommended allowance all over the study period, but compatible with fairly adequate lactational performance. They responded the additional energy stress of lactation by enhancing metabolic efficiency, increasing energy intakes, reduction physical activities and mobilizing body reserves. Another finding in this study was that the reduction in body fat-free mass may be the one way that women meet the energy demands of lactation like the reduction in body fat mass. The results from this study suggest that current recommended additional energy need during lactation, 2.09MJ/d(500kcal/d), is too high for healthy Korean women. Our data also indicate that the changes of body composition and energy balance at earlier postpartum are extremely different from those at later periods.

DNA markers can determine the genotype of many species. Single nucleotide polymorphism (SNP) detection is difficult without sequencing but it becomes easier with sdCAPS method. Here an experiment was performed for developing molecular markers using two SNPs, CSatpB-SNP and CSycf1-SNP, of chloroplast in cucumber plants. Properly designed primers with nucleotide sequences for restriction enzymes proved success of PCR and efficacy of digestion by the restriction enzymes. Then these markers were used to study the genotyping of cucumber breeding lines and cultivars obtained from various sources in respect of their chilling stress response. We confirmed that a U.S. cucumber line, 'NC76' known to possess a nuclear factor for the chilling tolerance showed the chloroplast genotypes related to chilling tolerance. However all Korean cucumber cultivars tested in this study showed the chloroplast genotypes related to chilling susceptibility. In conclusion, to develop chilling tolerant cucumber, both maternal and a nuclear factors related to chilling tolerance should be transferred from 'NC76' when 'NC76' is used as a female source and other elite lines as recurrent parents.

Purpose: This study examined the life experiences of the wives of men who were born with normal vision but gradually developed a visual impairment, with particular focus on their way of facing and coping with their life crisis. Method: A narrative approach was used to not only understand women's experiences within sociocultural contexts, but also reveal the subjective meaning of their personal life stories through their own voices. A purposive sample of three participants having husbands unexpectedly diagnosed with visual impairment during their marriage was recruited. The data were analyzed using the narrative analysis methods suggested by Clandinin and Connelly. Results: The wives took the crisis of their husbands' visual impairment as an economic crisis of the family. They faced a variety of difficulties, including extreme despair, role changes, and economic burdens. On the other hand, they tried to keep the family secure through a range of coping strategies that were motivated by compassion toward the husbands, maternal affection for the children, and a sense of responsibility for their families. Conclusion: This study revealed the need for financial support for temporarily disadvantaged families. In addition, various nursing and counseling programs for the family members will also be needed to help recover the family functions.

Purpose: The purpose of this study was to investigate the effects and characteristics of health care programs for pregnant women with gestational diabetes mellitus (GDM) in Korea. Methods: This study was conducted according to the Cochrane Collaboration's systematic literature review handbook and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses reporting guideline. We searched eight international and domestic electronic databases for relevant studies. Two reviewers independently selected the studies and extracted data. For each study, information on the research method, participants, characteristics of the program, and results were extracted using a previously established coding table. The National Evidence-based Healthcare Collaborating Agency's risk of bias assessment tool for non-randomized studies was used to assess the risk of bias of the included articles. A qualitative review of the selected studies was performed because the interventions differed considerably and the measured outcomes varied. Results: Out of 128 initially identified papers, seven were included in the final analysis. The risk of bias was evaluated as generally low. Health care programs for pregnant women with GDM showed positive effects on blood glucose control. Anxiety and depression were reduced, and self-management and self-care behavior, self-efficacy, and maternal identity improved. Conclusion: Our study provides clinical evidence for the effectiveness of health care programs for pregnant women with GDM, and its results can be used to support the development of health care programs for GDM. More well-designed research is needed on GDM, especially studies that deal with emotional stress and apply a family-oriented approach.

Due to the abundance of information in Nuclear DNA, it has a magnificent phylogenetic resolution. Moreover, because they show biparental inheritance, it has proven to be superior to organelle DNA, which has a limited number of genes and only shows maternal lineage. In particular, the transcriptome, which includes much nuclear DNA but is relatively inexpensive to analyze, can provide valuable insights into evolution through selection analysis and enable gene function research. This study's dataset includes 45 transcriptomes (16 generated for this study). It aims to explore the evolutionary history of Apioideae by comparing the results of the phylogenetic analysis with gene tree discordance and chloroplast phylogeny. The results confirmed the taxonomic positions of Peucedanum terebinthaceum, Ligusticum tachiroei, and Cymopterus melanotilingia and proposed a genus change for Glehnia littoralis. High gene tree discordances were identified in recently diverged clades, suggesting frequent hybridization and introgression. In the most recently diverged tribe of Selineae, the highest number of PSGs (positively selected genes) has been confirmed, which is inferred to be due to the geological and climatic diversity of their originated habitat, Central Asia. These genes include those related to responses to growth and drought, oxidative, and salt stress. In particular, the CYP97A gene confirmed as PSGs in Bupleurum latissimum is inferred to be a result of adaptation to the light-limited environment of Ulleungdo Island, as it is associated with the efficiency of photosynthesis.

Purpose: This study aimed to identify parental factors associated with smartphone overuse in preschoolers. Methods: A systematic review was conducted according to PRISMA guidelines. Relevant studies published in peer-reviewed journals from 2009 to June 2019 were identified through systematic search in 10 electronic databases (PubMed, CINAHL, Cochrane Central, EMBASE, Web of Science, NDSL, KISS, KMbase, KoreaMed, and RISS). Standardized effect sizes were calculated to quantify the associations of parental factors with smartphone overuse in preschoolers using meta-analysis. Results: A total of 30 cross-sectional studies involving 7,943 participants met the inclusion criteria. The following were negatively correlated with smartphone overuse in preschoolers: mother's parenting self-efficacy (r=-.35), mother-child attachment (r=-.28), mother's positive parenting behavior (r=-.28), mother's positive parenting attitude (r=-.25), and father's parenting involvement (r=-.15). Further, maternal factors such as smartphone addiction tendency (r=.41), parenting stress (r=.40), negative parenting behavior (r=.35), negative parenting attitude (r=.14), smartphone usage time (r=.26), employment status (r=.18), and age (r=.12) were positively correlated with smartphone overuse in preschoolers. Conclusion: Several parental factors influence smartphone overuse in preschoolers. These findings emphasize the need to assess and enhance the parental factors identified in this study to prevent smartphone overuse in preschoolers. Accordingly, we recommend the development of preventive interventions to strengthen parent-related protective factors and mitigate risk factors.
