  • The exact estimation of physical growth by Obesity level has important meaning to the health care and evaluation on adolescent girls. So this study tried to clear the relationship between weight and body fat by using data for the height, weight of 124 elementary school children and high school student in Seoul. Then this study tried to show the physical growth pattern and various characteristics by Obesity level by using longitudinal for the height, weight of 1113 high school students in Seoul, and it also tried to show what influencing factors on the physical growth of this aged population. The result could be summarized as follows. 1. The relationship between weight and body fat(%) has 0.81475(r) at age 9 and 0.69361(r) at age 18. Also the relationship between weight and lean body muscle(LBM %) has -0.81470(r) at age 9 and -0.64729(r) at age 18. 2. The weakness, normal and obesity groups were classified by Obesity level. In case of weakness group showed the very low Obesity level at age 8 to 11, in case of obesity group showed the high Obesity level at age 15 to 18. Also Rohrer index was decreasing tendency up to age 12 in weakness group and increasing tendency over age 14 in obesity group. 3. When the height and weight growth pattern was compared, height growth was superior to weight growth at age 9 to 14.5 in normal group. But weight growth was inferior to height growth at age 9 to 14.5 in normal group. In obesity group, weight growth was superior to height growth at age 7 to 18. On the other hand the height growth of weakness group was superior to the normal group and the obesity group except age 11 to 12. 4. On height velocity curve by PHV age obesity group showed the most growth amount per year(9.00Cm/yr), and the next is normal group(8.77Cm/yr), weakness group(8.70Cm/yr). Then the difference between PHV age and PWV age was within 1 year in these three groups. 5. In these three groups, height velocity curve by menarcheal age showed the PHV before 2~3 years of menarcheal age. And weight velocity curve by menarcheal age showed the remarkable PWV before 1 year of menarcheal age.

  • Purpose: The purpose of present study was to develop a method for assessing the chronological age of Korean adults based on the relationship between age and size of pulp cavity using dental radiographs of mandibular first molars. Methods: A total of 325 dental radiographs of Korean adults with known age and gender were selected for the study (199 males and 126 females) which were taken in the period between January 2009 and June 2014 at the Pusan National University Dental Hospital. The measurements were carried out on both orthopantomographs (OPGs) and intraoral periapical radiographs of mandibular first molar and the following ratios were calculated: pulp chamber floor height ratio (F/L), pulp chamber ceiling height ratio (R/L), and pulp chamber depth ratio (D/L). Results: The ratios of measurements on intraoral periapical images of mandible first molar generally produce more reliable data than the measurements on OPGs. The pulp chamber floor height ratio and pulp chamber thickness ratio showed significant correlation with age, whereas the pulp chamber ceiling height ratios showed weak correlation with age. It was found that the best correlations between the ratios and age were found for pulp chamber thickness ratios (r=-0.731 to -0.751). The multiple regression models were derived using 3 ratios that were significantly correlated with age. The determination coefficients ($R^2$) of the models ranged from 0.556 to 0.596. Conclusions: Our results indicate that the pulp chamber thickness and pulp chamber floor height in mandibular first molar are an age-dependent variable in adults which can be used to estimate age with reasonable accuracy. The higher image quality of dental radiographs will probably narrow the age estimation error and improve dental age estimation.

  • The present study showed WHtR to be significantly better than BMI and WC for prediction of metabolic-related diseases in the middle-aged and older people in Korea, based on Bayesian ordered probit model analysis. The variations of WC, BMI and WHtR were compared according to the number of metabolic-related diseases such as hypertension, dyslipidemia, stroke, myocardial infarction, angina pectoris and diabetes. It was found that the three measures showed the similar variation except a very few extreme cases for age less than 40. For subjects over the age of 40, WC was not significant and WHtR gave more influence in greater variability than BMI on the number of metabolic diseases. Also, the rate of change for WHtR was higher than for BMI as the number of metabolic-related diseases increased. Specifically, the difference of the marginal effect of WHtR between no disease and only one disease was 1.81 times higher than that of BMI. Moreover, it was pointed out that the threshold value of WHtR for obesity should be considered differently by age.

  • 목적: 질병이 환자에 끼치는 주관적인 영향을 반영하고, 환자의 전반적인 경과와 예후를 나타내는 지표로써 삶의 질 개념이 널리 사용되고 있다. 이때 질병은 환자 자신뿐만 아니라 가족들의 삶에도 상당한 영향을 미치게 되고, 특히 아동이 질병에 이환 되었을 경우 이러한 영향은 더욱 커지리라고 생각된다. 이에 주의력결핍 과잉 행동장애 환아의 보호자를 대상으로 삶의 질의 정도를 알아보고, 삶의 질에 영향을 주는 다른 요인은 무엇인지를 알아보고자 하였다. 방법: DSM-IV 진단기준에 의해 주의력결핍 과잉행동장애로 진단된 아동 38명의 보호자를 대상으로 하였고, 나이와 성별을 맞춘 정상아동 16명의 보호자를 건강대조군으로 하였다. 환아 보호자군과 건강대조군에 대하여 자체 제작한 사회인구학적인 변인에 대한 설문지, 한국판 세계보건기구 삶의 질 간편형 척도(WHOQOL-BREF)를 사용하여 각각 변인의 차이를 비교하였다. 결과: 1) 한국판 WHOQOL-BREF 척도에서 전체 삶의 질 총점과 전반적인 삶의 질, 척도내의 4개의 영역인 신체적 건강 영역, 심리적 영역, 사회적 관계 영역, 환경영역에서 환아 보호자군과 대조군에서 의미 있는 차이는 없었으나, 신체적 건강 영역의 하부척도인 일상생활수행능력 척도$(3.0{\pm}0.7\;vs.\;3.6{\pm}0.7)(p=0.008)$와 심리적 영역에 해당되는 자존감척도$(2.8{\pm}0.7\;vs.\;3.3{\pm}0.7)(p=0.049)$에서 유의하게 감소되어 있었다. 2) 전체 삶의 질 총점은 교육년수가 길수록 높았다(r=0.437, p=0.007). 3) 신체적 건강 영역 (영역 1)은 교육년수가 길수록 높은 점수를 보였고(r=0.370, p=0.024), 하부 척도 중에서는 수면과 휴식 척도가 교육연수와 양의 상관관계를 보였다(r=0.429, p=0.008). 4) 심리적 영역(영역 2)과 관련 있는 요인은 없었으나, 하부 척도인 긍정적사고 척도는 교육년수가 길수록 점수가 높았으며 (r=0.346, p=0.036), 자존감 척도(r=-0.337, p=0.039)와 사고 학습 기억능력 척도(r=-.341, p=0.036)는 보호자의 나이가 많을수록 점수가 낮았다. 5) 사회적 관계 영역(영역 3)과 관련 있는 요인은 없었으나, 하부척도 중 성적활동 척도는 교육년수가 길수록 높은 점수를 보이고 있었다(r=0.344, p=0.037). 6) 환경 영역(영역 4)은 교육년수가 길수록 점수가 높았지만(r=0.482, p=0.003), 환아의 나이가 많을수록 낮은 삶의 질 수준을 보고하였다(r=0.328, p=0.044). 한편 하부 척도 중에서는 신체적 안전 척도(r=-0.414, p=0.010), 거주환경 척도(r=-0.429, p=0.007), 새로운 정보나 기술의 취득 척도(r=-0.382, p=0.018), 의료서비스 및 사회보장서비스 척도(r=-0.351, p=0.031)가 환아의 나이와 음의 상관관계를 보였으며, 신체적 안전척도는 보호자의 나이가 많을수록 삶의 질이 낮음을 보고하였다(r=-403, p=0.012). 한편, 새로운 정보나 기술의 취득척도(r=0.406, p=0.013), 여가활동 척도(r=0.464, p=0.004), 교통 척도(r=0.363, p=0.027)은 교육연수가 길수록 높은 점수를 보고하였다. 결론: 주의력결핍 과잉행동장애 환아의 보호자가 느끼는 주관적인 삶의 질은 건강대조군에 비해 나쁘지 않았다. 그러나 환아의 나이가 많을수록, 보호자의 교육연수가 낮을수록 스스로 느끼는 삶의 질의정도가 낮았으므로 이에 대한 관심이 필요할 것이다.

  • Purpose: We evaluated the long-term results of endoscopic Deflux$^{(R)}$ injection for treating vesicoureteral reflux (VUR) in children. Methods: Between September 2004 and September 2014, 243 children (137 boys and 106 girls) with a mean age of 53 months underwent Deflux$^{(R)}$ injection. Our clinical protocol included radionuclide voiding cystography (RNC) at postoperative 3 months, 1 year and 3 years to assess the VUR resolution. Results: The cure rates at 3 months, 1 year, and 3 years by patients were 70.8%, 64.3%, and 65.6% for the total patients and 79.2%, 75.2%, and 76.4%, for the ureters, respectively. The recurrence rate of postoperative febrile urinary tract infection (UTI) was 20% in patients without VUR at postoperative 1 year. Twenty patients undergoing ureteroneocystostomy (UNC) significantly had younger age (P=0.003), higher VUR grade (P<0.001), and lower success rates of Deflux$^{(R)}$ injection (P<0.05). On univariate analysis, older age (P=0.014) and lower grade of VUR (P=0.031) were the significant predictors of a successful outcome. But there was none on multivariate analysis. Younger age, especially age of 0-12 month-old, was the only significant predictor of postoperative febrile UTI recurrence on both univariate and multivariate analysis. Conclusion: Deflux$^{(R)}$ injection is efficacious with a low complication rate for the anti-reflux procedure in children. There is low recurrence rate of UTI though VUR persists, and high probability of no VUR at 3 years if no VUR at 1 year. It is recommendable not to perform follow-up RNC at 3 years routinely if no VUR at 1 year.

  • Investment in research and development (R&D) is critical in the information technology (IT) firms, where newer and better technology is a quintessential goal that directly affects innovation and competitive advantage. This study investigates how R&D investment influences firm performance and value, and how the effect of R&D investment differs between IT hardware and software firms. We also analyze the relationship between firm age and R&D investment in order to identify learning effects on continuous R&D investment. The empirical investigation in this study, based on longitudinal archival data from 2001 to 2010, found a significant effect of R&D investment on firm performance in IT firms. Further, this study demonstrates causal relationship between firm age, and verifies that learning effects are present in R&D investment. Moreover, the results are found to differ between IT hardware and IT software firms.
