Purpose: The purposes of this study were(a) to identify smoking behavior by following a cohort representative of the population of 4th grade elementary schoolers in South Korea over a four-year period(2004-2007), and(b) to explore predictors of smoking initiation among non-smokers in Wave 1. Methods: Secondary data, the Korea Youth Panel Study, was analyzed in this study. First, frequencies or percentages were calculated to identify smoking behavior(i.e., smoking initiation, smoking intensity, and smoking duration). Second, binary logistic regression analysis was performed to examine significant factors related to smoking initiation. Results: Smoking initiation and daily smoking were more pronounced when the participants entered middle school. In bivariate analysis, statistically significant predictors of smoking initiation were loneliness at school, self-control, delinquent behavior, depressive symptoms, and stress. However, after controlling for other factors, only a high level of risk-taking tendency and a greater number of delinquent behaviors remained statistically significant. Conclusion: Based on greater involvement in smoking among first-year middle schoolers, smoking prevention strategies should be provided to elementary schoolers rather than middle schoolers. A risk-taking tendency and delinquent behaviors should be considered as proxy measures to detect the high-risk group for smoking initiation.

Purpose: This study was conducted to investigate the relationship between self-esteem and coping skills among middle school students. Method: The participants were 674 students in three middle schools in GyeongGi-Do. The data were collected from June 10 to 20, 2005. The instruments used were the Rosenberg Self-esteem Scale and the Ways of Coping Checklist. The data were analyzed using the SPSS-Win 12.0 program. Result: Self-esteem showed a significant positive correlation with positive coping skills (r= .162. p= .000). As for the positive coping skills, there was a significant difference by grade (F= 4.69, p= .010), relationship with parent (F=4.036, p= .02), and relationship with siblings (F=3.902, p= .02). As for the negative coping skills, there was a significant difference by grade (F=3.05, p= .04), condition of living with parents (F=3.559, p= .02), economic status (F=3.736, p= .02), relationship with sibling (F=3.408, p= .03), and troubling matters (F=5.422, p= .005). Conclusion: Positive coping skills may be effective for adjustment because they positively related to self-esteem. Self-esteem and coping skills should be considered when an adolescent's mental health enhancement program is designed.

Sleep is a vital, highly organized process regulated by complex systems of neuronal networks and neurotransmitters. Normal sleep comprises non-rapid eye movement (NREM) and REM periods that alternate through the night. Sleep usually begins in NREM and progresses through deeper NREM stages (2, 3, and 4 stages), but newborns enter REM sleep (active sleep) first before NREM (quiet sleep). A period of NREM and REM sleep cycle is approximately 90 minutes, but newborn have a shorter sleep cycle (50 minutes). As children mature, sleep changes as an adult pattern: shorter sleep duration, longer sleep cycles and less daytime sleep. REM sleep is approximately 50% of total sleep in newborn and dramatically decreases over the first 2 years into adulthood (20% to 25%). An initial predominant of slow wave sleep (stage 3 and 4) that peaks in early childhood, drops off abruptly after adolescence by 40% from preteen years, and then declines over the life span. The hypothalamus is recognized as a key area of brain involved in regulation of sleep and wakefulness. The basic function of sleep largely remains elusive, but it is clear that sleep plays an important role in the regulation of CNS and body physiologic processes. Understanding of the architecture of sleep and basic mechanisms that regulate sleep and wake cycle are essential to evaluate normal or abnormal development of sleep pattern changes with age. Reduction or disruption of sleep can have a significant impact on daytime functioning and development, including learning, growth, behavior, and emotional regulation.

This documentary study explored the stages of human development and education in the Choson Dynasty with the use of "Non Eu, Ye Gi, So Hak, Tae Gyo Sin Gi, and Dong Yi Bo Gam. The findings were compared with Western writings of a comparable period. It was found that education in the Choson Dynasty was largely concerned with mental attitude and conduct in ordinary life (education for manners and living). Education claimed to stand for unity of knowledge and behavior. It was founded on a Confucian view of education with a saint as the ideal model to be emulated. In the early years, home influence was emphasized. This was later replaced by institutional education. Additional education frequently extended to ten years and even forty or more years for the development of leaders. Based on the above findings. It was concluded that (1) the Western stages of human development exemplified by the Puritans and by Rousseau were concerned only with progressive changes from the postnatal stage to adolescence but the stages or the Choson Dynasty applied to the entire life span, from prenatal life through old age: (2) the developmental stages of males and females were defined differently as a result of differences in educational contents and sex-role distinctions: (3) life span educational objectives were Confucian and the preparatory stages were long coming to fruition in late senescence: and (4) although education was centered on manners and based on Confucianism, much of human development in the Choson Dynasty corresponds to that of modern times.

Objectives: This study was conducted in order to identify the various influencing factors of dental caries according to the socio-economic characteristics and oral health behaviors across the life cycle among Koreans. Methods: The data were extracted from the 6th Korea National Health and Nutrition Examination Survey (2013-2015) and a total of 4,871 subjects with ages of 7 and over were selected. The data were analyzed using SPSS 21.0 for ${\chi}^2$-test and multi-logistic regression. Results: Significant differences were observed in the socio-economic characteristics, health behaviors and in the dental caries across the life cycle. The influencing factors of DT includes the type of health insurance (p<0.05) in school aged & adolescence, Oral health examination/year (p<0.01), Residence (p<0.05) in early adults, type of health insurance (p<0.001), Oral health examination/year (p<0.001), use of oral hygiene products (p<0.01) in late Adults, Oral health examination/year (p<0.05) and Gender (p<0.05) in old age. Conclusions: This study suggests that dental health promotion can be enhanced by regular checkup. The government must provide the people with better quality of oral health care and promotion across the life cycle in the near future.

A migraine is a recurrent, throbbing headache generally felt on one side of the head. Migraines usually begin in early childhood, adolescence, or young adult life. Its accurate pathogenesis is still unknown but migraines are caused by a rapid widening and narrowing of blood vessel walls in the brain and head. The classic migraine and the common migraine are the two main types. The onset of classical migraine may be signalled by visual disturbances in what is called the 'aura' stage. Visual aura is most common among the auras of classical migraine. Common migraine (or migraine without aura) and classical migraine may be accompanied by various combinations of symptoms such as nausea, vomiting, and sensitivity to light and sound. Recently we have exprienced 2 cases of migraine patients and whose conditions were improved through trigger point needling and Oriental medical treatment.

Ehlers-Danlos syndrome (EDS) VIII is an autosomal dominant inherited connective tissue disorder characterized by intractable periodontal inflammation, absence of gingiva, pretibial plaques, skin hyperextensibility, joint hypermobility, and tissue fragility with onset in the childhood or adolescence. In a recent report, heterozygous variants of the C1R or C1S related to the classical complement pathway were identified in families with history of EDS VIII. The current report describes a Korean 34-year-old female carrying a novel missense variant of C1R c.925T>G (p.Cys309Gly) and exhibiting early severe periodontitis, skin fragility, and joint hypermobility. The patient also had frontal, parietal, and temporal white matter brain lesions without definite vascular abnormalities on brain magnetic resonance imaging, which have not been surveyed meticulously in EDS VIII. Considering the genetic alteration of classic complement pathways in this condition, it is necessary to carefully observe multisystemic inflammation processes such as changes in brain white matter.

Long-chain fatty acid oxidation disorders (LC-FAOD) are an autosomal recessive inherited rare disease group that result in an acute metabolic crisis and chronic energy deficiency owing to the deficiency in an enzyme that converts long-chain fatty acids into energy. LC-FAOD includes carnitine palmitoyltransferase type 1 (CPT1), carnitine-acylcarnitine translocase (CACT), carnitine palmitoyltransferase type 2 (CPT2), very long-chain acyl-CoA dehydrogenase (VLCAD), long-chain 3-hydroxyacyl-CoA dehydrogenase (LCHAD), and trifunctional protein (TFP) deficiencies. Common symptoms of LC-FAOD are hypoketotic hypoglycemia, cardiomyopathy, and myopathy. Depending on symptom onset, the disease can be divided as neonatal period, late infancy and early childhood, adolescence, or adult onset, but symptoms can appear at any time. The neonatal screening test (NBS) can be used to identify the characteristic plasma acylcarnitine profiles for each disease and confirmed by deficient enzyme analysis or molecular testing. Before introduction of NBS, the mortality rate of LC-FAOD was very high. With NBS implementation as routine neonatal care, the mortality rate was dramatically decreased, but severe symptoms such as rhabdomyolysis recur frequently and affect the quality of life. Triheptanoin (Dojolvi^®), the first drug for pediatric and adult patients with molecularly confirmed LC-FAOD, has recently been approved by the US Food and Drug Administration in 2020. In this review, the diagnosis of LC-FAOD and treatment including triheptanoin are summarized.
