Toxocariasis is a parasitic zoonosis caused by infestation of humans with larvae of Toxocara canis, the common roundworm in dogs. Two syndromes have been identified : visceral larva migrans and ocular toxocariasis. In this study we were characterized proteinase activity in crude extracts from liver, lung, kidney and heart of mice infected with Toxocara canis and the dynamics of their changes in different stages of disease. The optimal pH was 5.5. In liver of mice infected with Toxocara canis, the maximun activity of proteinase was observed in 5 day post infection. In lung, the activity reached its maximun on 5th day in A group (infected with 100 embryonated eggs), and on 5th week in B group (infected with 50 embryonated eggs). In kidney, the maximum activity was shown at 6th week in A group, and in B group was shown at 10th day. In early infection, the activity reached its maximun in heart of mice infected with Toxocara canis. As we could see, the dynamics of the changes of proteinase activity in mice is similar in the case of the disease with other biochemical and immunological indices observed in toxocariasis.

Maxillary deficiency, anterior cross bite, constriction of maxillary arch, malaligned teeth are frequently observed in patients with cleft lip and palate. Surgery and orthodontics, combined intervention are needed to correct maxillary deficiency. Distraction osteogenesis that currently used has many advantages like less relapse tendency, more advancement of maxilla, capable in growing patients. In case 1, 18 years old girl with BCLP had severe midfacial deficiency and multiple missing of teeth. LeFort I osteotomy, followed by maxillary distraction osteogenesis utilizing rigid external distraction device(RED) system, was performed. After a 6-day latency period, distraction proceeded at a rate of 1mm per day (at 1st week, 1.5mm/day). Total advancement was 19mm. The RED device left in place for the additional 4 weeks for consolidation. After the RED device was removed, face mask was applied with elastic traction for 5 weeks. After achieving acceptable facial appearance and occlusion, orthodontic appliance was removed. The results after 4 years follow-up was sustained pretty well without aggravation of velopharyngeal function. In case 2, 22 years old man with UCLP had severe midfacial deficiency and palatally erupted upper 2nd premolars due to arch length discrepancy, but the anterior segment of maxillary did not show constriction and crowding. patient had no arch width discrepancy, crowding was concentrated on premolar region. Segmental LeFort I osteotomy was performed. After a 6 - day latency period, using internal distraction device, distraction proceeded at a 0.5mm per day(at 1st week, 0.75 - 1 mm/day). Total advancement was 15mm. After internal distraction device was removed, face mask was applied with elastic traction for 4 weeks. After surgical-orthodontic treatment, facial appearance and occlusion was improved pretty good, and after 46 months follow-up the result was retained well.

The purpose of this study was to develop and evaluate a nutrition education program to prevent breakfast skipping for elementary school children. Subjects were 102 5th grade students (51 boys, 51 girls) as the "education group" and 200 5th grade students (102 boys, 98 girls) as the "non-education group." The nutrition education program consisted of 4 lessons over an 8-week period. Teaching materials, including flash animation, panel, PowerPoint, and a bingo game, were developed for this education program. After education, there was significant increase in the percentage of students who had eaten breakfast every day, understood that breakfast has a great effect on health, and will eat breakfast every day in the education group compared to non-education group. Parents' positive behavior toward daily breakfast preparation and the percentage of parents who had their children eat breakfast every day increased significantly. The students of the education group responded positively to the questions of the benefit and importance of nutrition education. The flash animation received high marks, especially in terms of understanding of contents, content clarity, emphasis of the core content, delivery of necessary knowledge, and applicability of breakfast. This study shows the effectiveness of a 4-lesson nutrition education taught during an 8-week time period to induce changes in recognizing the importance of breakfast and in behavior toward breakfast consumption.

Based on 'Backpack-free day' and 'Unsupervised studying day' in the early 1980s, 10% of all schools in 2004 had at least 1 day of five-day classes a month as at least 2 days were enforced in 2006, and most elementary and middle schools had widely enforced the five-day class since 2012 March. The five-day class system expands the stage of studying from school to families and local societies to build an educational community related to school-family-local societies to provide various activities such as culture, art, sports, social, nature experiences on holidays to have the goal to foster creative future talents with proper personality understanding and considering others. In Busan, the five-day week class of Saturday program is being operated in various methods by national local government and public organizations. The Saturday program of local societies registered in the Saturday school of the information sharing networks are 2823 in total for the past 6 years which are being operated by national local government and public organizations. However, participation of students in the Saturday program is around 20% in 2012 March when Saturday holiday system was widely conducted. For this, problems in the Saturday programs that are currently being enforced are to be closely analyzed and participation expansion plans are to be made. Therefore, this study analyzes and investigates operation forms of Saturday programs conducted in Busan to propose an improvement plan to fulfill goals of Saturday programs and boost participation of students.
