This study aimed to explore the experience and nature of emotional care for elderly parent living alone for middle-aged adult who formed initial insecure attachment with his or her parent. To this end, 12 middle-aged people aged 45 to 60 (3 males and 9 females) were recruited as subjects of the study, interviewed in-depth, and analyzed using Colaizzi's phenomenological research method. As a result of the study, 60 constitutive meanings, 18 themes, and 4 thematic groups were derived for the experience of middle-aged adult who experienced insecure attachment to his or her parent and caring for the emotional needs of elderly parent living alone. Thematic groups included "negative experiences that caused emotional exhaustion," "emotional driving force in emotional care," "the role of helper in parental care," and "economic and physical content in emotional care". This study is meaningful in that it revealed the phenomenon of experiences of emotional care for parent living alone by middle-aged adult who had an initial unstable attachment with his or her parent to understand them and contributed to the provision of counseling data.

This study aims to examine the mediating effects of positive parenting attitudes, self-esteem, and depression on the relationship between parental happiness and children's happiness. To this end, the Korean Children and Youth Panel Survey 2018 were used. Structural equation modeling was implemented based on 2,551 data collected from fourth-grade children of elementary school and their parents. The happiness felt by the parents was found to have a positive correlation with positive parenting attitudes, self-esteem, and happiness perceived by the children, and a negative correlation with the children's depression. And, the happiness felt by the parents was found to affect the happiness of children by sequentially progressing through positive parenting attitudes, children's self-esteem and depression. Such results reflect how parents who perceive themselves to be happy tend to be warm, provide structure, and support the autonomy of their children. This also shows how such positive parenting attitudes encourage children to believe that they are valuable individuals and how this plays a role in reducing their sense of depression and enhancing their happiness.

Background: Parental attention is crucial for preventing childhood oral diseases. Mothers play a significant role in maintaining their families' oral health, and their educational level influences their children's oral health behaviors. This study investigates the impact of mothers' educational levels on adult oral health behaviors using data from a national survey. Methods: This study employed a cross-sectional analysis of secondary data. The data used were obtained from the 8th Korea National Health and Nutrition Examination Survey. Descriptive statistics were calculated to identify participant characteristics. Next, t-tests and one-way analysis of variance were conducted to examine the effects of the explanatory variables on the distribution of the dependent variable. Finally, logistic regression analysis was used to investigate the influence of the explanatory variable on the dependent variable, using "no education" as the reference value, and calculate the odds ratios. Results: Children of mothers with a college education or higher had a 1.13 times higher likelihood of receiving oral examinations than those whose mothers had no education. Children whose mothers graduated from college or higher had a 2.23 times higher probability of receiving preventative dental treatment than those whose mothers had no education. Children whose mothers graduated from college or higher had a 1.92 times higher probability of receiving scaling than those whose mothers had no education. Children whose mothers graduated from high school had a 1.35 times higher probability of receiving scaling than those whose mothers had no education. Conclusion: Developing oral health programs is important for low-educated and low-income parents to change theirs and their children's oral health behaviors/attitudes. This will help reduce oral health disparities among adults raised by parents of higher and lower socioeconomic statuses. Therefore, a comprehensive approach is essential for adults to maintain good oral health, regardless of variations in their parental educational levels during childhood.

This study intends to analyse the concept on the child-rearing of parents. Through analysis, several concepts on the child-rearing would be cleared, and therefore the groundwork of the theoretical framework can be constructed. The concepts were analyzed by the method of Walker & Avant(1995). The attribute of child-rearing is as follows; nutrition supply, affectionate mind, caring, growth development supporting, protecting, instructing, pregnancy, delivery etc. The proper child-rearing helps reinforce child development, mother-infant attachment, social disposition, parental-role contentment and family relationship. This study would be helpful to the establishment of child-rearing paradigm. And therethrough this result although helps construct proper child-rearing as well as theoretical groundwork.

The purpose of this study was to investigate parental beliefs about child development in the context of Korean culture by analyzing and interpreting normative expectations of the age in disciplining children as presented in books for domestic life education of the $Chos{\breve{o}}n$ Dynasty period. The method used for this study was the historical method. The literature used for analysis was the Naihun, Gyubeomseonyoung, Sasojol, Jongbo-Salimgyoungjai, and Hahagjinam. According to the analysis, the discipline of children began from the age of three. The selection of the age of three was based on the observation that 3-year-olds begin to have an understanding of events in their world. From 3 to 10, socialization of the $Chos{\breve{o}}n$ Dynasty period gave prominance to social competency in interrelationships, especially honor of elders, modesty and sex role typing.

To examine the parenting experiences of North Korean parents in South Korea, seven parents(a father, a grandmother and five mothers) were interviewed about their parenting beliefs, attitudes and behaviors. It was found that parents from North Korea felt a safe existence including safety from hunger in South Korea but they were afraid of the many cars and unfamiliar diseases in South Korea. They had many difficulties with unfamiliar child rearing practices and parental roles in South Korea. Their confusion about good parenting was compounded by psychological and physical after-effects of the escape from their native country. They found help in adjusting to parenting in South Korea by such social networks as child care centers.

본 연구에서는 한국인 아동의 우식치아로부터 분리한 S. mutans K7으로부터 HtrA gene을 동정하고 HtrA expression이 산성환경하에서 S. mutans의 생육에 미치는 영향을 알아보았다. S. mutans K7의 HtrA mutant strain은 산성환경에서 parental strain과 비교하였을 때, 생육에 있어서 상당한 차이를 나타내었다. 또한 Biofilm formation에 관여하는 GtfB, 와 GtfC의 발현량도 현저히 줄어들었다. 그리고 HtrA mutant strain에 HtrA gene을 삽입하여 HtrA의 발현량을 회복하였을 경우에는 acid stress하에서 control과 같은 nomal growth phenotype을 회복하였다. 이러한 결과들은 S. mutans K7에서 HtrA가 acid stress동안에 중요한 역할을 담당함을 제시하고 있다.

Korean ginseng, which contains ginsenosides and polysaccharides as its main constituents, is orally administered to humans. Ginsenosides and polysaccharides are not easily absorbed by the body through the intestines due to their hydrophilicity. Therefore, these constituents which include ginsenosides Rb1, Rb2, and Rc, inevitably come into contact with intestinal microflora in the alimentary tract and can be metabolized by intestinal microflora. Since most of the metabolites such as compound K and protopanaxatriol are nonpolar compared to the parental components, these metabolites are easily absorbed from the gastrointestinal tract. The absorbed metabolites may express pharmacological actions, such as antitumor, antidiabetic, anti-inflammatory, anti-allergic, and neuroprotective effects. However, the activities that metabolize these constituents to bioactive compounds differ significantly between individuals because all individuals possess characteristic indigenous strains of intestinal bacteria. Recently, ginseng has been fermented with enzymes or microbes to develop ginsengs that contain these metabolites. However, before using these enzymes and probiotics, their safety and biotransforming activity should be assessed. Intestinal microflora play an important role in the pharmacological action of orally administered ginseng.

Heterosis was studied involving two multivoltine silkworm breeds viz, APM1 and SLKSPM through rearing and isozyme analysis. A positive significant heterotic effect was observed in fecundity, hatching % and survivability. The heterobeltiosis was observed only in fecundity and hatching %. Isozyme analysis of ${\alpha}-esterase$ showed variation in loci and allelic expression. The allele with heterozygosity $(Est-2^{12})$ was observed at the Est-2 locus in $F_1$ progeny. Est-3 was observed in $F_1$ progeny, whereas it was completely absent in both parental lines. The present study suggests that the markers ($Est-2^{12}$ and Est-3) targeted for introgression may be useful for the improvement of fecundity and survivability as the phenomenon of heterosis was observed only in $F_1$ progeny.

A 245 bp segment of E. coli chromosomal replication origin, oriC, contains 11 repeats of the GATC sequence in which adenine is methylated by Dam methylase. Newly replicated oriC is hemimethylated. The parental strand of the newly replicated oriC is methylated, but the nascent strand is not yet methylated until methylated by Dam methylase. The hemimethylated oriC plays an important role in the regulation of chromosomal replication. Activity in the seqA mutant was identified to bind preferentially to hemimethylated DNA, but not to fully-methylated DNA. This activity may participate in the sequestration of initiation of chromosomal replication.
