Objectives The purpose of this study was to investigate the difference of brain activity between internet game overusers in adulthood and normal adults in a state of disembodiment. Methods The fMRI images were taken while the internet game overuser group (n = 14) and the control group (n = 15) were asked to perform the task composed of ball-throwing animations. The task reflected on either self-agency about ball-throwing or location of a ball. And each block was shown with either different (changing viewpoint) or same animations (fixed viewpoint). The disembodiment-related condition was the interaction between agency task and changing viewpoint. Results 1) In within-group analyses, the control group exhibited higher brain activation in the left precentral gyrus, the left inferior frontal gyrus, and the left insula. And the overuser group exhibited higher activation in the right cuneus, the left posterior middle occipital gyrus, and the left parahippocampal gyrus. 2) In between-group analyses, the control group exhibited higher activation in the right posterior superior temporal gyrus. And the overuser group exhibited higher activation in the left cuneus, and the left posterior middle occipital area. Conclusions These results show that the disembodiment-related brain activation of internet game overusers in adulthood is different from that of normal adults.

Objectives: This study was conducted in order to determine how the association between socioeconomic position(SEP) and health status changes with age among Seoul residents aged 25 and over. Methods: We utilized the 2001 and 2005 Seoul Citizens Health Indicators Surveys. We used self-rated 'poor' health status as an outcome variable, and family income as an indicator of SEP. In order to characterize the differential effects of socioeconomic position on health by age, we conducted separate multivariate analyses by 10-year age groups, controlling for sociodemographic covariates. In order to assess the relative health inequality across socioeconomic groups, we estimated the Relative Index of Inequality (RII). Results: The risk of 'poor health' is significantly high in low family income groups, and this increased risk is seen at all ages. However, the magnitude of relative socioeconomic inequality in health, as measured by the odds ratio and RII, is not identical across age groups. The difference in health across income groups is small in early adulthood (ages 25-34), but increases with age until relatively late in life (ages 35-64). It then decreases among the elderly population (ages more than 65). When the RII reported in 2005 is compared to that reported in 2001, RII can be seen to have increased across all ages, with the exception of individuals aged 25-34. Conclusions: The magnitude of health inequality is the greatest during mid- to late adulthood (ages 45-64). In addition, health inequalities have worsened between 2001 and 2005 across all age groups after economic crisis.

The authors examined the life of university students in Korea. Overall, the life illustrated by Korean university students was grouped into four themes as follows: 'never experienced critical thinking, don't have enough time to critically think,' 'looking for decisions and conclusions by someone else,' 'just doing my job although I don't want,' and 'I don't know what I am supposed to do for my own life.' Since participants of this current study spent their adolescence under the standardized education as well as the regulated direction, they did not experienced their proper independent life. Given the fact that Korean university students had troubled with their life transition into adulthood, more efforts are needed to change the social perceptions toward university students and to develop the appropriate action derived by colleges/universities in order to guide university students' healthy transition into adulthood.

Background: Sampling a healthy reference population to generate reference intervals (RIs) for complete blood count (CBC) parameters is not common for pediatric and geriatric ages. We established age- and sex-specific RIs for CBC parameters across pediatric, adult, and geriatric ages using secondary data, evaluating patterns of changes in CBC parameters. Methods: The reference population comprised 804,623 health examinees (66,611 aged 3-17 years; 564,280 aged 18-59 years; 173,732 aged 60-99 years), and, we excluded 22,766 examinees after outlier testing. The CBC parameters (red blood cell [RBC], white blood cell [WBC], and platelet parameters) from 781,857 examinees were studied. We determined statistically significant partitions of age and sex, and calculated RIs according to the CLSI C28-A3 guidelines. Results: RBC parameters increased with age until adulthood and decreased with age in males, but increased before puberty and then decreased with age in females. WBC and platelet counts were the highest in early childhood and decreased with age. Sex differences in each age group were noted: WBC count was higher in males than in females during adulthood, but platelet count was higher in females than in males from puberty onwards (P <0.001). Neutrophil count was the lowest in early childhood and increased with age. Lymphocyte count decreased with age after peaking in early childhood. Eosinophil count was the highest in childhood and higher in males than in females. Monocyte count was higher in males than in females (P <0.001). Conclusions: We provide comprehensive age- and sex-specific RIs for CBC parameters, which show dynamic changes with both age and sex.

This study was performed to describe the longitudinal management of recurrent temporomandibular joint (TMJ) ankylosis from infancy to adulthood in perspective of surgical and orthodontic treatment. A 2-year-old girl was referred with chief complaints of restricted mouth opening and micrognathia due to bilateral TMJ ankylosis. For stage I treatment during early childhood (6 years old), high condylectomy and interpositional arthroplasty were performed. However, TMJ ankylosis recurred and symptoms of obstructive sleep apnea (OSA) developed. For stage II treatment during early adolescence (12 years old), gap arthroplasty, coronoidectomy, bilateral mandibular distraction osteogenesis, and orthodontic treatment with extraction of the four first premolars were performed. However, TMJ ankylosis recurred. Because the OSA symptoms reappeared, she began to use a continuous positive airway pressure device. For stage III treatment after completion of growth (20 years old), low condylectomy, coronoidectomy, reconstruction of the bilateral TMJs with artificial prostheses along with counterclockwise rotational advancement of the mandible, genioglossus advancement, and orthodontic treatment were performed. After stage III treatment, the amount of mouth opening exhibited a significant increase. Mandibular advancement and ramus lengthening resulted in significant improvement in the facial profile, Class I relationships, and normal overbite/overjet. The OSA symptoms were also relieved. These outcomes were stable at the one-year follow-up visit. Since the treatment modalities for TMJ ankylosis differ according to the duration of ankylosis, patient age, and degree of deformity, the treatment flowchart suggested in this report could be used as an effective guideline for determining the appropriate timing and methods for the treatment of TMJ ankylosis.

Objectives: We examined which socioeconomic and intergenerational characteristics were associated with the level of intention to marry among Korean men and women in young adulthood. Method: Data came from 351 men and 391 women who were 25-34 years old, had never been married, and had at least one living parent. We conducted multiple regression analyses by gender after controlling for age and current romantic relationship. Results: Among the socioeconomic characteristics, more years of education was linked to both men's and women's higher levels of intention to marry. For women, having a secure, full-time job was related to greater intention to marry. For men, the higher their subjective socioeconomic status, the greater their intention to marry. Among intergenerational characteristics, both men's and women's positive attitudes toward supporting elderly parents were related to a higher level of intention to marry. For men, the frequency of providing instrumental support for their parents was negatively associated with the men's intention to marry. For women, higher levels of agreement with parents' responsibility to support their adult children as well as greater affection for their parents were positively related to greater intention to marry. Conclusions: The findings suggest that young adults' socioeconomic resources and the family context are important predictors of young adults' marital intentions. The results also reveal gender differences in the factors associated with young adults' marital intentions.

This study analyzes the difference in total cholesterol blood concentration according to dietary characteristics and health characteristics, as well as general characteristics, and the relationship between that factor and total cholesterol level according to the diagnostic criteria for dyslipidemia, and then compares and analyzes the relative risk ratio of significant factors for the occurrence of dyslipidemia. As a result, the total cholesterol blood concentration increases with age, so continuous management is necessary. Mainly, waist circumference level in early adulthood, regular exercise of appropriate intensity in late adulthood, and subjective health level management in the elderly are necessary. It was found that it was necessary to manage BMI level and eating-out level overall.

The purpose of this study was to form a linked model in which local institutions related to lifelong education for the disabled can cooperate based on the Daegu University K-PACE Center. The contents of the study started with recognizing the problem that the adult-centered lifelong education support system does not effectively cope with these factors, even though the independent life of people with developmental disabilities is a major factor determining the quality of life. Regarding this problem recognition, this study primarily emphasized the view that educational support for independent life of people with developmental disabilities should establish the context of the school foundation. The context of the school foundation is established for lifelong education centered on adulthood for people with developmental disabilities because the curriculum is embodied through the standards of subject matter education. In this regard, the Daegu University K-PACE Center, which established a curriculum that supports the independent life of people with developmental disabilities in terms of linking higher and lifelong education, actually reflects the context of the school foundation. As a result, this study prepared a strategy that could be considered as a transition to advance the curriculum organized by the Daegu University K-PACE Center, and the strategy was secondarily reflected as a procedure that could be linked to local lifelong education-related institutions for the disabled. Finally, this study presented a form of transition in which people with developmental disabilities can access the curriculum of lifelong education through the connection of local lifelong education-related institutions for the disabled, centering on the entire life of adulthood.
