The purpose of this study are two-fold; 1) to identify the differences in the view of environmental value between 6-years-olds and 12-years-old, 2) to identify the differences in the attitude towards animals and plants between male-and female students. To accomplish the purposes of this study, two researchers deeply interviewed ten 6-years-old and 12-years-old boys and girls, respectively. First, the interviewees are asked to rank six constituents in nature, human-being, tiger, ant, gingko tree, weed, and stone, from their views of environmental value. Then, the interviewees were asked to talk about their various interaction with animals and plants. The results of this study are as follows; 1) In evaluating the value of nature constituents, 12-years-olds tended to be affected by scientific knowledge. On the other hand, 6-years-olds tended to evaluate the value of nature constituents by their emotional feeling; 2) From the perspectives of environmental ethics, 12-years-olds showed attitudes in anthropocentric or holistic ethics. On the other hand, 6-years-olds showed attitudes in nonanthropocentric ethics; 3) In evaluating the value of nature constituents, 12-year-olds tended to consider the constituent′s instrumental values and 6-years-olds tended to consider their intrinsic values; 4) From the perspectives of "ethics of care", females, especially 12-years females tended to take care of plants. The results propose more emphasis of environmental "sensuous" in school environmental education. And male- and female students should be expected fairly in their environmental attitudes, especially in taking care of natural creatures.

Dental maturity is one of the index of physiological maturity indicators. To investigate the relationship between dental maturity and chronological age, the author took the orthopantomograms of 984 students, aged 7 through 17 years, having normal occlusion. The orthopantomograms were examined and calcification degree of each tooth on the left side was rated according to the method described by Demirjian. On the basis of findings of this study, the following results were obtained. 1. The root completion periods of mandibular permanent teeth were as follows; Central Incisor M $8.32{\pm}1.03\;years$ F $7.96{\pm}1.04\;years$ Lateral Incisor M $9.40{\pm}1.30\;years$ F $9.01{\pm}0.90\;years$ Canine M $12.81{\pm}1.24\;years$ F $11.42{\pm}0.94\;years$ 1st Premolar M $12.76{\pm}1.74\;years$ F $12.19{\pm}1.33\;years$ 2nd Premolar M $13.31{\pm}1.88\;years$ F $12.88{\pm}1.49\;years$ 1st Molar M $9.60{\pm}1.69\;years$ F $9.30{\pm}1.16\;years$ 2nd Molar M $14.38{\pm}1.73\;years$ F $13.96{\pm}1.63\;years$ 2. Sexual differences in same age group at given calcification stage were not significant statistically. 3. The developmental order in mandibular permanent teeth was as follows; a) central incisor, b) lateral incisor, c) 1st molar, d) canine and 1st premolar, e) 2nd premolar, f) 2nd molar.

The purpose of this study was to determine the probability of overweight throughout childhood in relation to the presence of overweight at birch or in early childhood, and presence of overweight in children's parents. Weight and height measures were collected at birth and at ages of 7, 10, 12 years from 655 6th grade primary schoolchildren. Childhood overweight was defined as a body mass index at or above the 85th percentile for age and sex, and overweight in children's parents as a body mass index at or above 27. The prevalence of overweight increased with age of the children. Overweight at birth was not associated with overweight at 12 years of ages. However, overweight at 12 years old was already related to overweight at 7 years old. In comparison to non-overweight peers, overweight children at ages 7(OR = 7.64, 95% CI = 4.32-13.51) and 10 years(OR = 19.69, 95% CI = 11.42-33.94) had a higher rick of becoming overweight at 12 years of age. Among children who was overweight at age 7years, 60.7% remained overweight 5 years later, Yearly increment in BMI of overweight children was larger than that of non-obese children (1.15-1.65kg/m$^2$vs 0.50-0.71kg/m$^2$. As compared with the lower case in mealy increment of BMI, the probability of being overweight at age of 12 years was greater in higher case. BMI values at age 7years were positively correlated with BMI values at age of 10 and 127ear,i, and with annual increments in BMI. But those relationships with birth weight were not observed. Children were at greater risk for overweight if at least ogle parent was overweight. The odds ratio for child overweight associated with maternal overweight was 2.41(95% CI = 1,13-5.IS), and those associated with paternal overweight 1.70(95% CI = 0.92-3.17). And parents' BMIs were positively correlated with children's BMI values and yearly BMI increment. In conclusion, overweight at early childhood and annual inclement in BMI can be important in predicting the prevalence of overweight and the risk that overweight will remain after 7 years of age. The risk of being overweight throughout the childhood increases by the parents'overweight.

Objective: Codeine may result in death or respiratory depression in children, particularly who are rapid metabolizer of CYP2D6, therefore it should be used cautiously among children under 12 years of age. This study was to investigate the prescribing pattern of codeine among children according to the age group, prescribed diagnosis, type of medical service and medical specialties. Method: We used Korea Health Insurance Review and Assessment Service-National Patient Sample (HIRA-NPS) database. Study subjects included inpatients or outpatients, who were prescribed codeine between January, 1, 2011 and December, 31, 2011. Contraindicated use of codeine was defined as the use of codeine at least one times under aged 12. Age groups were subclassified according to the <2 years, 2-4 years, 5-8 years, and 9-11 years. Frequently prescribed diagnosis (ICD-10), type of medical service, and medical specialties were also described among codeine users under aged 12. Results: Codeine users were 6,411 inpatients (9,958 prescriptions), and 3,397 outpatients (6,258 prescriptions), respectively. Codeine prescription under 12 years of age were 2.1% (210 prescriptions) among inpatients, and 12.3% (776 prescriptions) among outpatients (p-value<0.05). Outpatient prescriptions of codeine under 12 aged were issued mostly from primary care clinics and frequent diagnosis were unspecified bronchopneumonia (51.6%), and vasomotor rhinitis (23.7%). Conclusion: This study found prescribing of codeine under 12 aged is common in outpatient and primary clinics. Nationwide and community-based efforts should be needed to reduce inappropriate prescribing among children.

This study was done to understand nonpharmacologic pain management for pediateric patients and nurses' knowledge and attitudes toward it. The aim of this study was that which method did the patient's use according to the nurses' age, and how did they effectively use these methods in their field. The subjects of this study were 77 nurses working in the Pediatric unit in the Kyung Medical Center from September 2 to 15, 1999 using questionnaire form. The results of this study were as follows : 1. We divided the subjects into four groups : Younger than one year old, 1-6 years, 6-12 years, 12-18 years group. In the group younger one year old, most of the nurses participating in this study used speaking in soft quiet tones, supportive touch, toys, pacifiers. In the group of 1-6 years, they used speaking in soft quiet tones, toys, distracting attention, story talking, and visual stimulus. In the group of 6-12 years. they used pop-up books, providing information, cold therapy, speaking in soft quiet tones, supportive touch. In the group of 12-19 years, most of them used providing information, controling respiration and supportive touch. 2. The effective nursing intervention used in their field are speaking in soft quiet tones, pacifiers and nesting with blanket in the group of younger than one year old. Un the group of 1-6 years old, speaking in soft quiet tones, toys, and supportive touch were effective method in the control of nonp-harmacologic pain management. In the group of 6-12 years old, story talking, supportive touch, and speaking in soft quiet tones were effective method and in the group of 12-18 years old, providing information, cold therapy and supportive touch were effectively used to control nonpharmacologic pain management. 3. To compare the general characteristics and non-pharmacologic pain nursing intervention, in the group of younger than one year, touching stimuli is widely used. In the groups of 1-6, and 6-12 years old, visual and audio method were widely used. In the group of 12-18 years old, sensitive intervention were used as well as education, information and guided imagery. In conclusion, there was no significant difference in nurses' demographic characteristics, child's age and nonpharmacologic pain management. There was significant difference only in the nurses working area, that is nurses working in the surgical department used more audio-visual-tactile pain management methods than medical department.

The complete blood count and serum biochemical parameters are essential tools for diagnosis and monitoring of physiological and disease conditions in dogs. These parameters may be affected by the breed and age of dogs. This study aimed to compare the changes of complete blood count and serum biochemical parameters according to the increasing age in 156 Sapsarees. In this study, the Sapsarees were clustered into ten age groups: four to six months, seven to nine months, ten to twelve months, one year, two years, three to four years, five to six years, seven to eight years, nine to ten years, and, eleven to twelve years old. In the result of the complete blood count, the total red blood cell count (P<0.001), hematocrit (P<0.001), and hemoglobin (P<0.001) values were significantly increased from 4~6 months to 2 years old Sapsarees. While the mean corpuscular volume (P<0.001) and mean corpuscular hemoglobin (P<0.001) values were significantly increased from 4~6 months to 3~4 years old. The mean corpuscular hemoglobin concentration was significantly (P=0.037) increased from 4~6 to 10~12-month-old Sapsarees. Total white cell count was significantly (P<0.001) decreased from 1 year to 9~10 years old. The result of differential white blood cell count showed that neutrophil count was significantly (P<0.001) increased from the age 4~6 months to 11~12 years old Sapsarees, whereas, lymphocyte (P<0.001), monocyte (P<0.001), and eosinophil (P=0.042) counts were significantly decreased from 7~9 months to 7~8 years, 4~6 months to 9~10 years, 3~4 to 5~6 years old, respectively. In the serum biochemistry result, the creatinine concentration was significantly (P<0.001) increased from 4~6 to 10~12 months, but significantly (P=0.006) decreased from 7~8 to 10~12 years old. Phosphate concentration was significantly (P<0.001) decreased from 3~4 to 9~10 years old, but significantly (P=0.021) increased from 9~10 to 11~12 years old. Calcium concentration significantly (P<0.001) decreased from 10~12 months to 11~12 years old. Total protein concentration significantly (P<0.001) increased from 4~6 months to 2 years old. While concentrations of albumin (P=0.004) and globulin (P<0.001) was significantly increased from 4~6 months to 3~4 years old, and from 4~6 months to 11~12 years old, respectively. The alkaline phosphate concentration was significantly (P<0.001) decreased from 4~6 months to 2 years old. We found that there are differences in the hematological parameters in relation with the increasing age in Sapsaree breed.
