In order to develop a picture book for desirable eating habits of young children, the contents of nutrition education in picture books were analyzed. A total of 128 picture books were analyzed: 42 picture books from the Nuri-curriculum teacher's guide (Nuri), 40 picture books recommended by the National Library for Children & Young Adults (NLCY), and 46 picture books published by the Center for Children's Food-service Management (CCFM). As a result of analysis of dietary guidelines for Koreans, the item that appeared most frequently in picture books was 'Consume a variety of foods every day' (28.91%). The second most common dietary guidelines in the picture books was 'Enjoy a diet that incorporates local ingredients and is environmentally conscious' (21.88%). As a result of examining the main goal of 'eating right' in the Nuri Curriculum, 'healthy food' accounted for 36.72% and 'eating a variety of food' accounted for 30.47%. 'Eating with the right attitude' 4.69%, 'valuing food' 3.13%, and 'dining etiquette' 6.25% were low. Therefore, it is necessary to develop and distribute picture books that reflect the contents that are insufficient.

This study was carried out to investigate the effect of egg shell calcium salt types and egg shell membrane on calcium metabolism in rats. Sprague-Dawley male rats, 4 weeks of age, were fed on free-calcium diets for 2 weeks after adjustment period. Rats weighing approximately $247{\pm}2.3g$ were divided into 6 groups and were fed on the experimental diets containing 0.2% calcium for 4 weeks. Experimental groups were as follows; {ES(M+)} (egg shell powder diet with egg shell membrane), {ES(M-)} (egg shell powder diet without egg shell membrane), {AC(M+)} (egg shell calcium acetate diet with egg shell membrance), {AC(M-)} (egg shell calcium acetate diet without eg shell membrane), {GC(M+)} (egg shell calcium glucuronate diet with egg shell membrane) and {GC(M-)} (egg shell calcium glucuronate diet without egg shell membrane). Bone length of femur was significantly different by the types (p<0.05) of egg shell calcium salts. Bone mineral density of femur showed the highest level in AC(M-) group. Calcium content of femur and calcium absorption rate were higher in egg shell calcium salt groups than in eg shell powder groups. Calcium absorption rate and retention were significantly different (p<0.05) among the types of eg shell calcium salts and were higher in the AC(M-) group than in the other groups. Alkaline phosphatase activity, parathyroid hormone and osteocalcin levels of serum showed no significant difference among the experimental groups. From the above results, it is concluded that bioavailability of calcium is higher in groups of egg shell calcium salts compared to those in egg shell powder, even though egg shell membrane has no effect on calcium metabolism. Thus, these findings suggest the possibility of using egg shell calcium salts as a functional food material related to calcium metabolism.

We introduced the physiological responses of aging, active aging and also suggest the impact of physical exercise on body health status and elderly immunity. In this purpose, we searched the Pub Med data base for the articles (include our experimental papers) and review papers having the terms 'Aging', 'Active aging' and 'Physical activity and elderly' in the title, published from 1999 until 2018. The results were as follows: Exercise training has been extensively studied about the reduction of inflammation, oxidative stress, disease, and aging in syndrome X patients and elderly. Combined and aerobic or resistance exercise training could reduce obesity, insulin resistance, type 2 diabetes and hypertension. Exercise training has been extensively studied in cancer settings as part of prevention or treatment strategies. From this research, regular exercise has the potential to target tumor growth through regulation of inflammation and immune responses such as lactate clearance, NK cell activation (innate immunity), activation of cytotoxic immune cells, T cell activation (adaptive immunity), and immune surveillance. However, Endurance physical activity not only induces thermogenesis and diverse sports injuries but also elicits mobilization and functional enhancement of monocytes, neutrophils (which is caused by the cytokine changes such as TNF-alpha, IL-1) whereas it suppresses cell mediated immunity causing to increased susceptibility to inflammation and infections like cough and URTIs (upper respiratory track infections) in young and especially in elderly people. Therefore, Strategies to prevent physical fatigue, sports injuries include avoid overtraining, Adequate recovery and various type of rest during and after physical activity and assuring adequate nutrition supplementation such as glutamine, vitamin B, vitamin C, carbohydrate, ion or berry-contain sports beverages is helpful in physically active elderly.

Esthetics is important in restoring maxillary anterior area. Alveolar bone resorption and loss of interdental papilla may be minimized by immediate implantation. Previous studies showed successful results with the immediate implantation in healthy extraction socket, while many of these studies objected the immediate implantation into extraction sites with periapical lesions. Recent studies, however, reported successful results of the immediate implantation into extraction sites with periapical lesions with careful debridement of extraction sockets and general medication of antibiotics prior to implantation. A 73-year-old female visited the department of Prosthodontics in ${\bigcirc}{\bigcirc}$ University Dental Hospital with the chief complaint of fallen post-core and crown on left maxillary incisor. Although the incisor was with vertical root fracture and periapical lesion, the immediate implantation following the extraction of tooth was planned. Thorough socket debridement, irrigation with chlorhexidine, and tetracycline soaking were followed by immediate implantation. The general medication of antibiotics (Moxicle Tab.$^{(R)}$, 375 mg) was prescribed before and after the surgery. Immediate provisional restoration was delivered two days after the surgery, and the definitive metal-ceramic restoration was placed about six months later after reproducing the emergence profile from the provisional restoration. This case presents satisfying result esthetically and functionally upto two years after the placement of prosthesis with the harmonious gingival line and no loss of marginal bone.

Ectopic eruption and impaction of canines is a frequently encountered clinical problems. The incidence of impaction ranges between 1-3%. The cause of canine impaction can be the result of localized factors or can be a polygenic multifactorial inheritance and associated with other dental anomalies. The general dentist and pediatric dentist should know how to properly diagnose and manage potential disturbances in the eruption of maxillary canine. Diagnosis of impacted canine at age 8-10 years can significantly reduce serious ramifications, including surgical exposure and orthodontic traction as well as root resorption of the lateral incisors. Extraction of primary canine would be one of the method to prevent the impaction. The surgical procedure should be designed to minimize the destruction of periodontal tissue of impacted canine. Closed eruption technique is thought to be optimal method of surgical exposure compared with other methods. An overview of the incidence, sequela as well as the surgical periodontal, and orthodontic consideration in the management of impacted canine was presented.

In the case of congenital malformation, acquired trauma, or maxillectomy by neoplasm, the defect in maxilla is combined with nasal cavity, maxillary sinus and oral cavity. This results in abnormal function in pronunciation, mastication, and swallowing. In this situation, the purposes of prosthodontics are also applied. The purposes of obturator for acquired maxillary deficiency patients are restoring pronunciation, mastication, and swallowing, and make patients comfortable and esthetic satisfaction. Reducing weight of the obturator makes edentulous ridge heathy and functional. It also improves patients' comfort. Hollow obturator also reduces unnecessary stress because improves physiologic function, as it weights less than 6.55-33.06% compare to usual one. This case presents the double-processing method for maxillary obturator in the patient treated hemi-maxillectomy due to malignancy neoplasm. We report this case because the patient acquired functional and esthetic satisfaction from double-processing obturator.

Ossifying fibroma is a relatively slow growing tumor, and likely to have presented for some years before its clinical diognosis. The usually well circumscribed nature of ossifying fibroma in jaws lends itself to relative ease of excision and hence the favorable therapeutic results. On occasion, however, particulary in juvenile patient, if maxilla the tumor assumes an aggressive behavior. In that case, because the tumor grows invasively, resection with a margin of healthy tissue is indicated. The case presented is 34 - year old female. The patient had noticed a gradual swelling of the right side of the face approximately 2 months in duration correlation with a intermittent pain on the right maxillary molar area. Palpation disclosed firm swelling on the right anterior and lateral walls of the maxillary sinus extended to the maxillary tuberosity area. The radiographic examination revealed soft tissue mass with multiple dense round calcifications with destruction of anterior and posterolateral wall of the right maxillary sinus and right alveolar process, and hard palate. The mass totally obliterated maxillary sinus and extended to the pterygopalatine fossa. The histologic diagnosis from the biopsied specimen revealed ossifying fibroma. The tumor mass was resected by subtotal maxillectomy procedure due to a recent rapid infiltrative growth. In 5 months of postoperative follow - up period, the patient has favorable prognosis.

The purpose of this study was to elucidate the effects of 12 weeks rope jumping and Swiss ball exercise (55 to 75% HRR: 3 times a week) on body composition and bone formation markers in young children. Forty eight participants were divided into two groups, the exercise group (n=24) and the control group (n=24). All items were assesed before and after exercise program. The results of this study are as follows; 1. Body composition: In the comparison of mean changes before and after exercise program execution on body composition within each group, the exercise group showed significant increases in height, weight, fat mass and %fat. The control group showed significant increases in all items. The interaction effect between groups and time didn't appear a significant difference. 2. Osteocalcin: In the comparison of mean changes before and after exercise program execution in osteocalcin within each group, the exercise group didn't appear a significant change and the control group were significantly decreased in girl children. The interaction effect between groups and time didn't appear a significant difference. 3. Alkaline phosphatase: In the comparison of mean changes before and after exercise program in Alkaline phosphatase within each group didn't appear a significant difference in exercise group and control group. The interaction effect between groups and time showed a significant difference. In conclusion, for young children in the stage of the formation of bone mineral contents, rope jumping and Swiss ball exercise are postive effect in promoting their growth and bone health, but osteocalcin concentration did not changes. Thus, further research is required to consider intensity and duration of exercise on bone formation markers of young children's.

This study was performed in order to identify the relation between bone nineral density and life styles of some of Korean colleage students. A total of 121 college students were assessed through bone mineral density test on femoral neck and lumbar spine using dual energy X-ray absorptiometry(DEXA). The survey about their lifestyles with a self-rating questionnaire, was conducted from September 2014 to November 2014. SPSS 18.0 Program was used for those research data analyses such as the frequency analysis, the cross analysis. The percentage of the osteoporisis, osteopenia and normal groups were 0.0%, 24.8% and 75.2%. BMI, Regular menstrual cycle, Walking and Regular exercise in adolescence were positively related with T-score. But Using time of electronic devices was negative related with T-score. It can be concluded that desirable life style in time of college students and adolescence is important for their bone health. The necessity of preparing guideline for preventing bone disease in old age connected with the school curriculum should be recognized to the public and educational authorities.
