Objectives The purpose of this study is to find out the relationship between parents' heights and predicted height of the children who had been treated in the growth clinic of oriental medical hospital. Methods The study was conducted with 253 children who visited Oriental Medical Hospital from July 2010 to June 2012. They were analyzed by reviewing the children's chart and correlation analysis to find out the relationship between the two heights. Results In distribution of the sex and the age, sex were similar, but boys who came to the clinic were averagely younger than the girls. In predicting adult height by TW3 method and mean parent's height, correlation in the girls was higher than the boys, especially the girls after their first menstruation. Parents' heights were related to both the boys and the girls, but mother's height was more closely related. Predicted heights of the boys before secondary sex characteristics were correlated with the child's height, but rather correlated with parent's both heights after secondary sexual character and found to be more relevant to father's height. The girls' predicted heights before their menstruation were not correlated with father's height, but with mother's. Their heights after their first periods were correlated with parents' both heights, but more correlated with father's height. Conclusions This study helps set proper periods and goals of growth treatment based on the correlation between parents' height and predicted adult height according to TW3 method.

ZigBee 보안에서 네트워크 키나 링크키의 전달 및 상호 인증은 ZigBee Alliance 규격에 포함되어 있으나, 마스터키를 안전하게 각 노드에 전달하기 위한 방법을 제공하지는 않는다. 마스터키를 전송하는 과정이 안전하지 않은 채널을 통해서 전달하기 때문에 마스터키가 직접적으로 노출되는 단점을 가지고 있다. 또한 ZigBee Alliance에서는 보안에서 가장 핵심인 trust center 역할을 코디네이터가 하도록 정의하고 있다. 새롭게 PAN에 조인하는 디바이스마다 코디네이터와 키 연결을 해야 하기 때문에 코디네이터는 부하가 집중되고, 악의 있는 디바이스에게 직접적으로 위험에 노출되는 단점이 있다. 몇 개의 디바이스만 키 연결을 할 때는 문제가 되지 않지만 네트워크가 거대해지면 코디네이터에서 발생하는 트래픽 양이 증가하면서 코디네이터의 부하가 증가하게 된다. 본 논문에서는 이러한 문제를 해결하기 위해서 Parent-Child 키 연결 알고리즘을 제안하였다. 제안한 알고리즘은 두 가지 구조로 되어있다 일방향 해쉬 체인을 사용해서 안전하게 마스터키를 전송할 수 있는 마스터키 전송알고리즘과, 새롭게 PAN에 조인하는 디바이스가 효율적으로 키 연결을 할 수 있게 child 노드와 parent 노드끼리 키 연결을 하는 Parent-Child 네트워크 키 전송 알고리즘으로 구성되어 있다. 디바이스가 마스터키를 가지고 있는 경우에는 제안한 방식이 기존 방식보다 키 연결 시간이 $200{\sim}1300ms$ 정도 더 좋은 성능을 보였고, 디바이스가 마스터키를 가지고 있지 않은 경우에는 제안한 방식이 기존 방식보다 키 연결 시간이 $400{\sim}500ms$정도 더 좋은 성능을 보였다.

The purpose of this survey was to investigate the prevalence of obesity, eating habits and life styles of children. This survey was carried out anthropometry and questionnaires in 180 male and 141 female students of fifth-grade at Dongmak elementary school. The results are summarized as follows : 1)18.2% of the male and 19.3% of female students were obese. Underweight group was 10.5% of the male and 15.0% of the female students. 2) Average height of male and female students were 142.0㎝, 144.0㎝ and weight of those were 35.8㎏ and 37.1㎏ respectively. The height and skinfold thickness of the triceps in female students were significantly higher than those of male students and body fat content in female students was significantly lower than that of male students. There was no difference in BMI, RW and RI between male and female students. The average BMI, RW, RI were 17.7, 25.4, 124.0, respectively. 3) The student's height was positively related to parent's height and moth's weight. There were significantly positive correlation between mother's and subject's weight. BMI, RW and RI were positively related to parent's BMI. 4) 78.3% of male and 51.8% of female students had prejudice for special food, and 45.5% of male and 34.5% of female students had an overeating habit. Male students had significanthy higher rate than female in both cases. Average eating time per meal was 18.9 minutes for male and 21.0 minutes for female students. Experience for taking nutrient supplement in male student was more than that in female. Obese group had prejudice for special food, overeating habit and rapid eating rate more than any other groups. The prevalence of obesity among the children is gradually increasing. Therefore, in order to prevent progress into adulthood obesity, nutrition education including the right perception for obesity and eating behavior modification was needed.

Objectives : The purpose of this study was to have better data and to make efficient clinical reviews about children's growth based on two methods; X-ray of hand, and ultrasound of calcaneus. Methods : The study was composed of 100 patients(50 of boys and 50 of girls) who visited in department of pediatrics, O O university oriental hospital considering growth and their development. Bone age was measured by the TW3 method's RUS score in simple X-ray image of hand and bone density through ultrasonic image of calcaneus. To predict children's estimated height, their parent's height, bone age, and present height's percentile was measured. Results and Conclusions : 1. The bone age results from X-ray image of hand and ultrasonic image of calcaneus were correlated. Younger children have older bone age from hand's X-ray than the one from calcaneus's ultrasound. Older children have older bone age from calcaneus's ultrasound than one from hand's X-ray. 2. Predicted adult height by bone age(BH) of hand's X-ray and BH of calcaneus's ultrasound were correlated, but predicted adult height by inheritance(IH) was not correlated with others. 3. Bone age and predicted adult height were correlated with age, height, weight, BMI, and especially with age and height. 4. Measuring bone age by X-ray image of hand and ultrasonic image of calcaneus was simple and effective way of estimating children's growth and development.

Objectives: The purpose of this study is to analyze the causes of short stature through a clinical review of factors related to childhood height growth. So we can find the way to meet the needs of the heightism which is widely spread among modern people. Methods: Among 160 patients who came to Andong B oriental clinic for the purpose of growth therapy, 112 children whose height was smaller than other normal children were analyzed. When the children first came to the clinic, we checked their height and weight. The parents' height was recorded through a questionnaire. The relationship between obesity index and height growth was examined through growth plate test and Inbody test. We want to identify the genetic factors related to parental factors based on the data of the parent height. Results: For short stature children, weight was often normal or low. When we examined the relationship between parental genetic factors and child growth, we found that they were more influenced by father's height rather than mother's. We investigated the correlation between skeletal maturity and the five viscera. There was no apparent correlation between skeletal maturity and the five viscera but we found that there was some degree of relevance. Conclusions: For short stature children, the weight was often normal or low and parental genetic factors were more influenced by father than by mother. In the case of bone maturity it did not show a direct correlation between the five viscera.

Objectives: This study was conducted to investigate the associations between obesity and the children's Nutrition Quotient (NQ) and to further examine the relationships between NQ and mini dietary assessment (MDA) of their parents. Methods: The subjects were 355 children aged 3 to 5 years and their parents in Dongducheon. We collected parental-reported NQ questionnaires for children and MDA of parents. Anthropometric measurements, height, weight and BMI by BIA were measured in children. Overweight and obesity were determined according to age- and sex-specific BMI percentile from the 2007 Korean national growth chart. Statistical analyses consisted of the chi-squared test, ANOVA, partial correlations and logistic regression analysis adjustments for parents BMI. Results: Approximately 20.8% of preschool children were classified as overweight or obese. Underweight children showed a significantly higher score for balance than overweight children. The NQ of the children was $61.9{\pm}11.6$, and NQ scores and their parents' MDA did not exhibit any significant differences according to degree of obesity. After adjusting for parent's BMI, children's BMI was significantly correlated with balance and moderation among NQ factors. Parent's MDA showed significant correlation with their children's NQ, balance, diversity, moderation, regularity, practice and NQ grade, except for diversity of father. Additionally, NQ grade had a significantly increased (150.1%) odds ratio (OR) of being overweight (95% CI 1.008-2.234). Conclusions: These results show that NQ for children is influenced by their parents' MDA and BMI. Furthermore, our findings support the association between overweight prevention and improvement of NQ grade among preschool children.

본 연구는 아동의 기질특성이 신체발육에 영향을 주는가를 알아보기 위해 설계되었다. Thomas와 Chess에 의해 개발된 기질설문지의 한국 표준화 판을 이용하여 3세에서 7세 사이의 남녀 아동 395명의 기질을 측정하였다. 동시에 각 아동의 신장과 체중을 측정한 후 한국 소아 신체 발육 표준치에 근거하여 신장 및 체중 절대치를 백분율 값으로 전환하였다. 기질의 난이도 지수인 요인 A 점수 및 9가지 기질범주 점수와 신장 및 체중 백분율 값 및 신장에 따른 체중 백분율 값 사이에 상관분석을 실시하였다. 가족 평균 월 수입액에 따라 7단계로 분류한 가정 경제력을 통제변수로 하여 경제력을 통제하였다. 그 결과 기질적으로 어려운 아이일수록 동일 연령의 아동들에 비해 체중이 낮았으며, 동일한 신장을 갖는 아동들 중에서도 체중이 낮은쪽에 포함되었다. 이런 경향은 여자 아동들에서 두드러졌다. 이 결과는 기질특성이 심리적 발달뿐만 아니라 신체 성장과도 관련이 있음을 보여주는 것이다.
