Objectives: This study was conducted to investigate the vitamin D status and to determine the association between serum 25-hydroxyvitamin D [25(OH)D] concentrations and consumption frequencies of vitamin D rich foods in Korean adults and older adults. Methods: Subjects were 10,374 adults and 2,792 older adults participating in the 2008-2009 Korea National Health and Nutrition Examination Survey (KNHANES). Consumption frequencies of vitamin D rich foods were estimated by using a qualitative food frequency questionnaire (FFQ). Eleven food items such as beef, egg, mackerel, tuna, yellow corvina, pollack, anchovy, mushroom, milk, yogurt, and ice cream were selected as vitamin D rich foods based on previous research. Results: The proportions of deficiency (< 12 ng/mL), inadequacy (12-20 ng/mL) and sufficiency (${\geq}20ng/mL$) of serum 25(OH)D concentrations from June to November and December to May in adults were 8.8%, 42.3%, 48.8%, and 28.2%, 52.8%, 19.1%, respectively. The proportions of deficiency, inadequacy and sufficiency of serum 25(OH)D concentrations from June to November and December to May in older adults were 10.1%, 32.4%, 57.5%, and 24.1%, 45.4%, 30.5%, respectively. The mean serum 25(OH)D concentrations in adults were positively related to the consumption frequencies of mackerel, anchovy, all fish, milk and milk dairy products. The mean serum 25(OH)D concentrations in older adults were positively related to the consumption frequencies of yellow corvina and negatively related to the consumption frequencies of ice cream. Conclusions: Our results suggest that Korean adults were more deficient in serum 25(OH)D concentrations than older adults. The consumption of vitamin D rich foods may affect vitamin D status in Korean adults. Further studies are required to confirm these findings.

본 연구는 최초 노숙진입 시기 차이에 따른 남성 청년 노숙인 두 그룹의 노숙경로를 밝혀 구체적인 노숙의 원인을 추적하는 것을 목적으로 한다. 기존의 노숙 원인에 대한 논의는 구조냐 개인이냐의 이분법적 원인론에 머물러 있거나 노숙에 영향을 미친 복잡한 원인을 다루지만 결국 이를 단순화시켜 설명하는 경향이 있었다. 본 연구는 각 청년노숙인 사례의 노숙 위험요인을 도출하고, 사례의 생애 경험의 맥락 속에서 노숙에 영향을 미친 핵심위험요인의 연대기적 배열을 통해 좀 더 세밀하게 위험요인간의 인과성을 추적하여 노숙진입의 경로를 살펴보았다. 그 결과 청년기에 노숙에 진입한 그룹(A1)과 10대 때부터 노숙을 경험한 바 있는 그룹(A2)은 노숙의 진입 경로가 상이함을 확인하였다. 양쪽 모두 청년기에 극한의 상태인 노숙을 경험하고 있다는 공통점이 있지만, 전자의 경우는 가족, 사회로부터 입은 외상으로 인해 정신적인 고통에 시달리고 이로부터 이탈해 고립을 경험하다 노숙에 이르게 된 경우로 대표된다면 후자의 그룹은 이미 청소년기부터 위기청소년의 상황이 시작되었고, 학교, 가정에서의 불안정성이 매우 높았던 것을 확인할 수 있었다. 청소년기의 노숙 경험이 청년기로 곧장 이어지는 경우는 많지 않았지만 비노숙 기간이 잠시였을 뿐 청년기에 노숙으로 재진입하고 있었다. 이러한 결론을 통해 성인기의 삶의 토대를 다져야 하는 청년기에 극단의 상황에 처한 청년들의 위험요인과 진입경로에 따른 차별화된 개입, 사례관리, 상담에 대한 정책적 접근이 필요하다는 것을 제언하였다.

Objective: The aim of this study was to evaluate the skeletal and dentoalveolar changes after miniscrew-assisted rapid palatal expansion (MARPE) in young adults by cone-beam computed tomography (CBCT). Methods: This retrospective study included 14 patients (mean age, 20.1 years; range, 16-26 years) with maxillary transverse deficiency treated with MARPE. Skeletal and dentoalveolar changes were evaluated using CBCT images acquired before and after expansion. Statistical analyses were performed using paired t-test or Wilcoxon signed-rank test according to normality of the data. Results: The midpalatal suture was separated, and the maxilla exhibited statistically significant lateral movement (p < 0.05) after MARPE. Some of the landmarks had shifted forwards or upwards by a clinically irrelevant distance of less than 1 mm. The amount of expansion decreased in the superior direction, with values of 5.5, 3.2, 2.0, and 0.8 mm at the crown, cementoenamel junction, maxillary basal bone, and zygomatic arch levels, respectively (p < 0.05). The buccal bone thickness and height of the alveolar crest had decreased by 0.6-1.1 mm and 1.7-2.2 mm, respectively, with the premolars and molars exhibiting buccal tipping of $1.1^{\circ}-2.9^{\circ}$. Conclusions: Our results indicate that MARPE is an effective method for the correction of maxillary transverse deficiency without surgery in young adults.

Background Speech problems are a common clinical feature of the 22q11.2 deletion syndrome. The objectives of this study were to inventory the speech history and current self-reported speech rating of adolescents and young adults, and examine the possible variables influencing the current speech ratings, including cleft palate, surgery, speech and language therapy, intelligence quotient, and age at assessment. Methods In this cross-sectional cohort study, 50 adolescents and young adults with the 22q11.2 deletion syndrome (ages, 12-26 years, 67% female) filled out questionnaires. A neuropsychologist administered an age-appropriate intelligence quotient test. The demographics, histories, and intelligence of patients with normal speech (speech rating=1) were compared to those of patients with different speech (speech rating>1). Results Of the 50 patients, a minority (26%) had a cleft palate, nearly half (46%) underwent a pharyngoplasty, and all (100%) had speech and language therapy. Poorer speech ratings were correlated with more years of speech and language therapy (Spearman's correlation=0.418, P=0.004; 95% confidence interval, 0.145-0.632). Only 34% had normal speech ratings. The groups with normal and different speech were not significantly different with respect to the demographic variables; a history of cleft palate, surgery, or speech and language therapy; and the intelligence quotient. Conclusions All adolescents and young adults with the 22q11.2 deletion syndrome had undergone speech and language therapy, and nearly half of them underwent pharyngoplasty. Only 34% attained normal speech ratings. Those with poorer speech ratings had speech and language therapy for more years.

Objective: Hallux valgus (HV) is a common musculoskeletal deformity that is accompanied with pain and continues to decrease one's quality of life and ability to perform daily life activities by affecting gait and static stability. Therefore, this study aimed to investigate the effect of the angle of HV (HVA) and to compare the one-legged stance and gait parameters in young adults with less HV and severe HV. Design: Cross-sectional study. Methods: Forty young adults were divided into two groups, where HVA ≥15° (n=20) was defined as HV, and HVA <15° (n=20) was defined as normal. For balance ability, the center of pressure (COP) path, velocity, length of axis of the COP path, deviation of the x-axis and y-axis, and percentage of foot pressure were measured, and gait, the foot rotation angle, step length, percentage of each phase of the gait cycle, time change from the heel to forefoot, and maximum pressure of the forefoot and midfoot were measured. Results: Significant differences were found in sway length and time change from heel to forefoot during walking between the normal and HV groups (p<0.05). Most parameters were not associated with the HVA, but parameters such as length of axis and time to change from heel to forefoot were significantly associated with the HVA (p<0.05). Conclusions: These results suggest that most one-legged stance and gait parameters were not significantly affected by the HVA in young adults; therefore, future studies are needed in order to address other dynamic parameters and other methods of gait analysis for detecting clinically meaningful conditions.

Purpose: As laptop use increases throughout the COVID-19 pandemic and its use outside of traditional workstations proliferates, it is imperative to expand the limited research available regarding ergonomic exposure. This study aimed to identify the effects of a laptop supporter on biomechanical characteristics in the wrist joint muscles of healthy young adults. Methods: This was a cross-sectional observational study design with thirty-four healthy young adults as participants. They conducted a typing exercise performed under two different conditions, which were with and without a notebook computer supporter. This study measured the biomechanical characteristics of the muscles of the wrist joints including the flexor carpi ulnaris (FCU), the flexor carpi radialis (FCR), the extensor carpi radialis longus (ECRL), and the extensor carpi ulnaris (ECU). Measurements were taken three times: before typing, immediately after typing for 30 minutes with a supporter, and immediately after typing for 30 minutes without a supporter. The statistical method to compare the three different measurement conditions was the repeated measures ANOVA. Results: The participants showed significantly different levels of dynamic stiffness in both the FCU before typing and immediately after 30 minutes of typing with a supporter, and showed significantly different levels of dynamic stiffness in the FCR before typing and immediately after 30 minutes of typing with a supporter. The dynamic stiffness level immediately after 30 minutes of typing without a supporter was significantly different than that immediately after 30 minutes of typing with a supporter. However, the muscle tone was not significantly different among the three different conditions. Conclusion: The results of this study revealed that a laptop supporter used to correct the eye level of the electronic screen increases the dynamic stiffness of the wrist joint flexors, so it is necessary to consider the neutral position of the wrist joint during typing.

Purpose: The purpose of this study was to investigate the effect of soleus muscle stretching on the muscle thickness and muscle tone of the tibialis anterior and peroneus longus muscles in healthy young adults. Methods: This study was an observational, cross-sectional study design in healthy young adults. Thirty healthy young adults participated in the study. To investigate the effect of agonist elongation on the muscles' antagonist and synergist characteristics, this study conducted the dynamic stretching of the soleus and plantarflexor muscles for 20 seconds. This study measured the muscle thickness and muscle tone of the soleus, tibialis anterior and peroneus longus muscles before stretching, immediately after stretching, and five minutes after stretching. Results: After analysis, the muscle tone of the soleus muscle was significantly decreased immediately after stretching (20.91±2.61Hz) compared to before stretching (21.83±2.78Hz). The muscle tone of the tibialis anterior was significantly decreased both immediately after stretching (21.76±2.73Hz) and five minutes after stretching (21.72±3.25Hz) compared to before stretching (22.61±3.29Hz). The muscle thickness of the soleus muscle was significantly decreased immediately after stretching (2.04±0.52mm) compared to before stretching (2.21±0.51mm) and was significantly increased five minutes after stretching (2.14±0.49mm) compared to immediately after stretching. Conclusion: The results of this study showed the static stretching of the soleus muscle changed the muscle tone of the tibialis anterior, but not of the peroneus longus muscle. This study suggests that the dynamic stretching of the agonist muscle would show meaningful muscle tone change in the antagonist.
