The Cyr61/CTGF/NOV (CCN) family is dynamically expressed in various tissues, including the nervous system, from the prenatal period to adulthood. However, major studies have been conducted only in limited fields, such as the cardiovascular and muscular systems, skeletal development, and cancer. In addition, although the CCN family is a secretory protein, very few studies have described its mechanism of secretion. Recently, it has been suggested that overexpression of CCN3 or intracellular accumulation due to problems in the secretory pathway can inhibit neuronal axonal growth. In this review, we have briefly summarized the structure and characteristics of the CCN family and its related diseases, with particular emphasis on the secretory mechanism and modifiers of the CCN family, newly identified in the nervous system.

Early-life environmental factors can have persistent effects on physiological functions by altering developmental procedures in various organisms. Recent experimental and epidemiological studies now further support the idea that developmental programming is also present in mammals, including humans, influencing long-term health. Although the mechanism of programming is still largely under investigation, the role of endocrine glucocorticoids in developmental programming is gaining interest. Studies found that perinatal glucocorticoids have a persistent effect on multiple functions of the body, including metabolic, behavioral, and immune functions, in adulthood. Several mechanisms have been proposed to play a role in long-term programming. In this review, recent findings on this topic are summarized and the potential biological rationale behind this phenomenon is discussed.

One of the main parameters in the analysis of skeletal remains in forensic anthropological cases is the estimation of age. This study aimed to investigate the correlation between age and the fusion status of the sternal junction. This cross-sectional study was carried out on 184 sterna from 94 females and 90 males obtained from known-age cadavers in the Thai population. By direct observation, the fusion stage of the manubrio-sternal and sterno-xiphoidal junctions was studied and divided into unfused and fused joints. The results showed that a large proportion of the sterna remain unfused throughout adulthood, with fusion observed in both young and old cadavers. Insignificant differences in the rate of fusion, the sexes and ages were observed. None of the sterna under 30 years of age in females and 32 years of age in males showed fusion of the manubrio-sternal and sterno-xiphoidal junctions. Based on the variability of the sternal fusions observed in this study, we highlighted a very limited role of the sternum alone in the estimation of age in the Thai population.

Young adults are not met adequately by the traditional public library service patterns, being compared for children and adults even though they belong to the main user groups in number. Adolescence is a unique developmental stage distinct from childhood and adulthood and it is fair to say that today's young adults face complex present and confusing future. Projects are made to address the full spectrum of the young adults needs and the important role of public libraries as partners to solve the social youth problems in the USA. The library professional organizations issued young adult service guidelines, recommendations, and manuals to assist public libraries to offer good service programs to young adults. This paper provides the basics of young adult services in the public libraries to help Korean public libraries acknowledge the importance of young adult services and improve the framework of young adult services.

The purpose of this study was to determine the association between drinking behaviors and the need for periodontal treatment. The data of 5,995 adults from the 2012 Korea National Health and Nutrition Examination Survey were categorized into young adulthood (19~39 years), middle age (40~64 years), and old age (${\geq}65$ years) and analyzed. Chi-square test was performed to determine those who needed periodontal treatment by the respondents' general characteristics and drinking behaviors, and logistic regression analysis was carried out to determine the impact of each drinking behavior on the need for periodontal treatment. The results of this study have confirmed that alcohol intake is a factor adversely affecting periodontal status; therefore, patients should know the fact that excessive alcohol intake and increased frequency of drinking may affect the prevalence rate of periodontal diseases. Moreover, moderate-drinking programs that can reinforce prevention of drinking so that dental hygienists can provide good oral health care should be developed. A systematic oral health promotion program should be introduced for constant prevention with the objective of activating oral health education that focused on middle-aged and young-adult people in pursuit of healthy aging society.

Purpose: The purpose of this study is that the college age is an important transition period from youth to adulthood. Nursing students are unfamiliar with their field of study and need to adapt to a large amount of academic and practical training, so that they can have a better college life. An attempt was made to determine the effect of exam anxiety, academic stress, and alcohol dependence on the academic achievement of nursing students. Research design, data, and methodology: The subjects of the study were 130 students from all grades who agreed to participate in the study after expressing convenience among students attending the Department of Nursing at a university in Gyeongnam. The data collection period was from August 15 to September 15, 2023. It was about a month. The data investigation was conducted through a self-report survey. Results: Results showed that significant variables included exam anxiety, academic stress, alcohol dependency, parent relationships, peer relationships, and major satisfaction, explaining a total variance of 31.9%. Among these, the most influential factor was academic stress (β=-.352). Conclusions: This study identify factors influencing the academic achievement of nursing college students and hopes to contribute to formulating strategies for their growth and competence development.

The present research is aimed at to examine the relationships between wisdom and age, also between wisdom and its psychological adaptation among middle and elder adults in Korea. Moreover, using data on 240 middle-aged and elder adults, the relationship between different aspects of wisdom and aging well were not only examined, but also explored age differences of wisdom through adulthood. The major findings from the study are summarized as follows. first, the wisdom scores of middle-aged and elder adults were significantly higher than those of young adults. While 'cognitive competency' and 'positive life attitude' factors had no significant differences. It means that 'cognitive competency' and 'positive life attitude' wisdom could be stable across adulthood. However, 'moderation and balance' and 'sympathetic interpersonal relationship' wisdom of elders were significantly higher than those of young adults. second, in middle and elder adults, Wisdom was found to be positively related with life satisfaction, well-being, death acceptance, experiences of positive emotion, generativity, ego integration, and positive life review. while on the other hand, contrast wisdom to be negatively related with depression, fear of death, perceived stress and experiences of negative emotion. The results from the study were examined by ecological validity of wisdom. Accordingly, a number of limitations and implications of the research were acknowledged.

Young adults are likely to start a new life style which may cause weight gain or obesity since leaving their parents for higher education or university. Whilst young people are slim in general, it is common to see them trying to manage their weight. Few studies have been carried out in Korea to support those changes in lifestyle that can result in weight gain in early adulthood. This study aims to identify prevalence of dieting as well as factors inducing weight gain among university students under unrestricted living conditions. A total of 99 university students were enrolled and asked to complete a questionnaire over a 3-day study period from June to September, 2008. T-test and $X^2$-test were applied to compare each behavior between weight gainers and maintainers. Logistic regression was also used for further analysis. Half of the participants used 'eat less' and 'exercise' as a way of dieting, and weight gainers tried to control their weight significantly more than weight maintainers. Most participants were engaged in very little exercise and were more likely to watch TV and use a computer. The time of lunch was proven as the only factor to predict weight change in the participants. As a result of this study, an intervention to promote exercise with friends or as a group is required to makeup for the lack of exercise among young adults. Further studies are also necessary to investigate how each meal time a day relates to the amount of food eaten. (Korean J Community Nutrition 14(4) : $374{\sim}382$, 2009)

Objectives: Bone health in early adulthood, as individuals approach peak bone mass, plays a critical role in preventing osteoporosis later in life. This study aimed to investigate the associations between lifestyle and dietary factors, anthropometric measurements, and urinary bone resorption markers in young adults. Methods: A cross-sectional study was conducted with 100 healthy Korean adults (50 men and 50 women) in their 20s and early 30s. Bone mineral density (BMD), anthropometric measurements, dietary intake (24-hour recall), and urinary bone resorption indicators (deoxypyridinoline and N-terminal telopeptide of type I collagen) were analyzed. Variables were compared between the osteopenia and osteoporosis groups (OSTEO group: 30% men and 60% women) and the healthy control group. Results: Men in the OSTEO group were significantly taller than those in the control group (P < 0.05). Women in the OSTEO group had significantly lower body weight and body composition (muscle and body fat) than those in the normal group (P < 0.01). Men in the OSTEO group had a significantly higher intake of animal calcium (Ca) than those in the normal group (P < 0.05). Women in the OSTEO group had significantly higher dietary fiber, vitamin A, Ca, plant Ca, and potassium intake than did those in the normal group (P < 0.05). There were no significant differences in caffeinated beverage consumption, eating habits, or urinary bone resorption indicators between the OSTEO and control groups of either sex. Conclusions: In our study of young South Korean adults, we observed low bone density levels, with particularly low BMD in taller men and underweight women. We found a higher nutrient intake in the OSTEO group, indicating the possibility of reverse causality, a phenomenon often found in cross-sectional studies. Therefore, there is a need to further elucidate dietary factors related to osteoporosis in young adults through prospective cohort studies involving a larger population.
