The objective of this study was to investigate the relation of serum calcium level, body mass index(BMI) with bone status expressed as broadband ultrasound attenuation(BUA) measured by quantitative ultrasound (QUS) and the occurrence of osteopenia among adult men and women. Two hundred eleven(63 male and 148 female) workers who worked in 4 different battery factories were recruited from March 2005 to October 2005. BUA was used as a surrogate of bone mineral density and measured at left calcaneous bone area. The BUA value transformed into T-score by WHO standard conversion criteria to determine osteopenia (-2.5

The present study sought to examine the association between an infant's anthropometric outcomes with maternal Dietary Inflammatory Index (DII) and Alternate Healthy Eating Index for Pregnancy (AHEI-P) scores during the third trimester of pregnancy. This prospective cohort study was applying 130 pregnant women, at the pregnancy training center in west Tehran, Iran (November 2020 to July 2021). The maternal dietary intake, and body mass index (BMI), and social economic level were evaluated. The data about birth weight, birth height, head circumference, and, gestational age at birth were extracted from each child's health records. The ultimate sample included 122 (93.8%) pairs of women/newborn children. The participants, mean age was 28.13 ± 4.66 years with gestational age between 28 to 40 weeks and the mean of BMI was 24.62 ± 3.51. Our outcomes, after adjustment for confounding factors, suggested that those newborn infants in the highest quartile of maternal DII score had a significantly lower weight (p < 0.001) and height (p = 0.05), in comparison to those in the lowest quartile, but not head circumference (p = 0.18). Moreover, after adjustment for confounding factors, results suggested that those newborn infants in the First quartile of maternal AHEI-P score had a significantly lower weight (p = 0.018) and, in comparison to those in the higher quartile. It appears that newborn infants with lower maternal DII and higher AHEI-P scores may have a better anthropometric outcome. Further longitudinal and in-depth qualitative and quantitative studies, with a longer-term follow-up, is warranted to support the integrity of our outcomes.

The study abroad phenomenon at an early age in Korea is increasing steadily. Increasing social demand for global leaders, disappointment in Korean educational system and economic growth are motivating more students to study abroad. The study abroad is a social phenomenon that is widespread across all social status in Korea. This study tries to examine the phenomenon in respect to social, psychological, educational and economical perspectives and seek future research questions. The findings suggest ways to improve Korean educational system, support students currently or planning to study abroad and to re-adjust in Korea after they come back. A balanced perspective is necessary in viewing study abroad phenomenon, rather than preventing, implementing stronger pulling factors in Korean educational system. It is necessary to hold the study abroad as another educational opportunity.

In this study we have evaluated daily beverage intake of the inhabitants in Seoul by a 24 hrs. recall procedure from 1145 respondents between pre-school children to adults in the period of June-July 1985. Estimates of consumption were made for each of seven beverage groups and comparisons were made within age, sex and body weight. Significant differences existed for certain beverage in each category analyzed. Total Fluid intake was greater for male than female at all ages and tended to be lower in the older age group with adjustment for differences in body weight. Milk was the major beverage among children while soft drinks were the predominant beverage for teen-ages. Alcoholic drinks represented the smallest component of daily fluid intake among women but were the second largest component of daily fluid levels for men over the age of 24 years.

Neonates have large inter-individual variability in pharmacokinetic parameters of many drugs due to developmental differences. The aim of this study was to investigate the factors affecting the pharmacokinetic parameters of drugs, which are commonly used in critically ill neonates. Factors that reflect physiologic maturation such as gestational age, postnatal age, postconceptional age, birth weight, and current body weight were correlated with pharmacokinetic parameters in neonates, especially preterm infants. Comorbidity characteristics affecting pharmacokinetics in critically ill neonates were perinatal asphyxia, hypoxic ischemic encephalopathy, patent ductus arteriosus (PDA), and renal dysfunction. Administration of indomethacin or ibuprofen in neonates with PDA was associated with the reduced clearance of renally excreted drugs such as vancomycin and amikacin. Therapeutic hypothermia and extracoporeal membrane oxygenation were influencing factors on pharmacokinetic parameters in critically ill neonates. Dosing adjustment and careful monitoring according to the factors affecting pharmacokinetic variability is required for safe and effective pharmacotherapy in neonatal intensive care unit.

The purpose of this paper is to examine bedroom-need norms and the relationship between normative deficits for bedroom sharing and housing space satisfaction of adolescent. Three cases were mainly considered to apply for adolescents to share a bedroom: maximum age and number limits of a child sharing a parents'bedroom, maximum age of an old child sharing a bedroom with its siblings of the opposite sex, and maximum age of an old child sharing a bedroom with its siblings of the same sex. The data were collected 400 eighth grade students in the three different size of regions, June-July, 1999 and 379 cases were finally analyzed. The result showed that the normative deficits for bedroom sharing was a statistically signiticant factor to explain housing space satisfaction of adolescents even though the condition of bedroom sharing was the most influencial variable. This reset supports the family housing adjustment behavior model of Morris and Winter.

This study reviews the current status of Korean first graders, their experience with early care and education (ECE) programs, and their participation in private and after-school education. The research also examines how school adjustment during the first grade is related to family income, types of ECE programs, and participation in private and after-school education. Using the first year data of the Korean Child and Youth Panel Survey (KCYPS) 2010, this study analyzes 752 first graders who attended only one of two types of ECE programs (child care centers or kindergartens), after which two 25% income extremes were examined. The analysis demonstrates that children from low-income households attended child care centers more often, while children from high-income households attended kindergartens more often. For both low-income and high-income groups, child care centers had a lower starting age and longer attendance periods than did kindergartens. High-income household children started attending ECE programs earlier, experienced more private and after-school education, and received a larger number of private and after-school educational lessons. For the second research purpose, children from low-income families showed better peer relations in school adjustment, while children attending child care centers showed better teacher relations than children attending kindergartens. Children with after-school education also exhibited better peer relations. These findings show the importance of government support for early learning, especially for low-income families and offer a foundation for developing private education polices for early childhood before and after school entry.

The study was done to provide basic data of medical quality evaluation after developing the comorbidity disease mortality measurement modeled on the severity-adjustment method of AMI. This study analyzed 699,701 cases of Hospital Discharge Injury Data of 2005 and 2008, provided by the Korea Centers for Disease Control and Prevention. We used logistic regression to compare the risk-adjustment model of the Charlson Comorbidity Index with the predictability and compatibility of our severity score model that is newly developed for calibration. The models severity method included age, sex, hospitalization path, PCI presence, CABG, and 12 variables of the comorbidity disease. Predictability of the newly developed severity models, which has statistical C level of 0.796(95%CI=0.771-0.821) is higher than Charlson Comorbidity Index. This proves that there are differences of mortality, prevalence rate by method of mortality model calibration. In the future, this study outcome should be utilized more to achieve an improvement of medical quality evaluation, and also models will be developed that are considered for clinical significance and statistical compatibility.

Due to the increasing concerns with the North Korean defectors, the researches have been increased.. However when compared with other areas, the researches about the North Korean defectors are rare. The sample size of this study is 171, which makes it possible to do statistical inferences. This study examines the adjustment stress and the effect of social support on the adaptation. As a demographic factors, gender, age and education are controlled. The context factors-the period of the stay in the third place, the period of residence and the existence of the education in Korea- are used as control variables. The research results show that the jobless is an important stressor. The structural social support affects the adjustment of stress as a whole and not individually. Among functional social support, the emotional social support is an important factor of adaptation, but the effect of structural social support is the opposite. Therefore, the adequacy of social support must be considered.

The purpose of the present study was to examine age differences in children's recall for information about aggression, prosociability, and social withdrawal of others and to investigate the impact of likeability on children's recall for social behavioral information. The subjects were 160 children, 20 boys and 20 girls each at 6, 8, 10, and 12 years of age. The subjects listened to descriptions of the social behavior of a hypothetical boy and girl and subsequently reported their recollections. These descriptions were drawn from Bukowski's(1990) stydy, the Pupil Evaluation Inventory, and the Pittsburgh Adjustment Scales. The data were analyzed with 2-way ANOVA, paired T-test, and correlation. Differences across the age levels were found in the number of behaviors correctly recalled for the behavioral descriptions of aggression, prosociability, and social withdrawal. Descriptions of aggressive behavior was recalled more when children listened to a hypothetical boy than to a hypothetical girl. Additional analyses revealed that at 6 years of age, children recalled more descriptions of aggressive and prosocial behavior than of withdrawal and at 10 and 12 years of age, children recalled more descriptions of withdrawal behavior than of aggressive and prosocial behaviors. The more negative the children's affective evaluations of the withdrawal behavior, the better they recalled the withdrawal behavior.
