The purpose of this study is to discover how therapeutic music making affects the way of communications in single-parent families. To do this, the study conducted a therapeutic music making program in two families consisting of a mother and a child. Songwriting, Ostinato-creating, improvisation imitation, and ensemble were used as musical interventions. The results of this study are following. First, the participant group B improved from 59 to 69.5 point after the program. However, the group A decreased from 81 to 75.5 point mainly due to frequent absences, differences in applying music. Second, the analysis of the results of verbal, nonverbal and musical responses from the program suggests that the group B gradually improved functional communications as each session develops. For the case of group A, at the initial stage, dysfunctional communications in verbal and nonverbal ones could be found. After the eighth session however, functional communications had increased. The result of the study shows that overall therapeutic music making has been an effective musical intervention in improving communication in single-parent families.

female smoking especially in the population of teenage girls is regarded as an important health problem as the young female smokers are increasing sharply. We surveyed 895 teenage girls(15-19 years of age) living in a rural community in Korea for their cigarette smoking habits and the relationship between smoking status of subjects demographic variables and view on other's smoking. Of the subjects 11.6% stated that they were currently smoking and 67.3% of current smokers began smoking regularly sometimes before high school. The average smoking period of current smokers waas 20.6$\pm$1.5 mounts and they smoked 7.5 cigarettes/day on an average. Their main reason for starting to smoke was curiosity. The parents attitude for their offspring was more undemocratic in smokers. Smokers had lower academic sachievement and they had the family system such as single parent more undemocratic in smokers. Smokers had lower academic achievement and they had the family sysstem such as single parent family or divorced parent family more often than did non-smokers. Smoking status of subjects was positively related to that of their parents siblings and friends respectively. Smokers accepted others' smoking more positively than did non-smokers. Above results show that cigarette smoking is prevalent among teenage girls living in a rural community and smoking of subjects are affected by demographic variables and their view on others' smoking. Therefore the prevention the prevention programs aimed at adolescent smoking should be started before middle school and they should be included all influencing environmental factors such as family school and mass media.

Purpose: This cross-sectional study was done to compare factors influencing young adolescents' aggression according to family structure. Methods: Participants were 680 young adolescents aged 11 to 15 years (113 in single father families, 136 in single mother families, 49 in grandparent families, and 382 in both-parent families). All measures were self-administered. Data were analyzed using SPSS 18.0 program and factors affecting young adolescents' aggression were analyzed by stepwise multiple regression. Results: Levels of young adolescents' aggression and all variables were significantly different among the four family structure groups. Factors influencing young adolescents' aggression were also different according to these 4 groups. For single father families, depression-anxiety and family hardiness significantly predicted the level of young adolescents' aggression (adjusted R square=.37, p<.001). For single mother families, depression-anxiety, gender, and friends' support significantly predicted the level of young adolescents' aggression (adjusted R square=.58, p<.001). For grandparent families, depression-anxiety and family support significantly predicted the level of young adolescents' aggression (adjusted R square=.58, p<.001). For both-parent families, depression-anxiety, family hardiness, and friends' support significantly predicted the level of young adolescents' aggression (adjusted R square=.48, p<.001). Conclusion: Nurses working with young adolescents should consider family structure-specific factors influencing aggression in this population.

Pleurotus ostreatus 'Miso' is a mutant strain showing white color in pileus from the known parent strain 'Wonhyeong 1'. Shape and several other characters also vary with culture conditions. Mating experiments were performed to understand interstrain mating relationship using monokaryons of the parent and the mutant strains. All monokaryons were grown from single spores isolated from freshly collected fruit bodies. Pairings were performed in 90 mm petri dishes on PDA. They were allowed to grow at 25 until two fronts of the advancing mycelia met and developed a conspicuous contact zone. The contact zone and the outer edges of paired colonies on each plate were examined for clamp connections. The parent and the mutant resulted in tetrapolar incompatibility in intrastrain crosses. In interstrain crosses, each monokaryotic tester strain of the parent strain was out-crossed to monokaryotic tester strains of the mutant. As a result of these crosses it was found that both strains share the same A and B incompatibility factors yielding 25% compatibility.

This study is designed as a non-equivalent controlled before-and-after quasi-experimental study by having a control group for the effect of the interpersonal caring music activity program in children of single-parent families. Data collection was carried out in 22 children of single-parent families as the study group and in 23 children as the control group recruited from 22 community centers for children located in N city from July to September, 2014. As the study tool, the Heart Rate Variability (HRV) was used to measure loneliness, self-esteem scale and the stress response. With the collected data and using SPSS 18.0 for Window program, the Homogeneity test between the study group and the control group was conducted by using t-test and ${\chi}^2$-test while the study hypotheses were verified by analyzing with the independent t-test. The results of the study are as follows. Loneliness and self-esteem of the subjects did not show significant difference in the study groups. The sympathetic nervous system activity (normalized LF) has been lowered and the parasympathetic nervous system activity (normalized HF) has been increased as the stress response, while the sympathetic and the parasympathetic nervous system activity ratio (LF/ HF) score was lowered with significant difference, which had supported the hypotheses. Based on these results of this study, the interpersonal caring music activity program can be utilized as a stress management program for the children of single-parent families during a short period of time.

The purpose of this study is to explore the economic hardship experiences of low-income single-parent families by COVID-19 to find ways to improve after COVID-19. To this end, 10 single parents with children under the secondary school age were recruited through snowball sampling method and in-depth interviews with economic activities, income, expenditure, and economic life. As a result of the study, participants suffered from unemployment and the disappearance of extra income activities in the early stages of COVID-19, additional expenses incurred by children's food and increased utility bills. In addition, it was recognized that COVID-19 has come to be more difficult and unequal to single-parent families of low-income women. It was found that the temporary living difficulties were resolved with disaster support funds, and it was helpful in the short term by spending according to priorities such as overdue monthly rent, food expenses, children's academy expenses, and purchasing home appliances. However, it was recognized that disaster support funds were inappropriate for customized disaster support and long-term and selective support was necessary. In the conclusion, to improve economic problems after COVID-19, it proposed measures to improve social welfare policies and practices

This study aimed to examine the impact of academic background on full-time employment and on other important issues concerning job security and care faced by single-parent youths. The study alse aimed to verify the effect of related support on full-time employment. The analysis targeted 262 single parents under 24 years of age who were raising their children, and the main results were as follows: First, the ratio of adulthood was high for those who were employed, and the academic achievement of full-time workers was also significantly high. However, the rate of discontinuities in school was also high among those who were employed, especially those seeking full-time employment, whose desire to stay in school was higher than that of other difficulties of single, teenage parents. Second, the vocational education experience of single, teenage parents was 32 percent overall, and the rate of those seeking full-time employment was also relatively high, reaching 44 percent. However, the results of this study did not verify the direct effect of vocational education experience on full-time employment nor the interaction effect of the academic background. Therefore, a thorough review of the effectiveness of a vocational education program for young, single parents wishing to gain employment is necessary. Third, the overall rate of those who received a public nanny service was 31 percent, while the rate of full-time workers who experienced this service was significantly higher reaching 59 percent. In the research model verification, single parents who received a public nanny service were 3.8 times more likely to get a full-time job than those who did not, and receiving a public nanny service showed a regulatory effect between academic studies and full-time employment. The higher the academic level of the parents, the higher their possibility of full-time employment.
