  • Special nutritional foods are one category of processed foods. In this category, 5 different food standards are defined in the current rule of the Korean Food Code ; that is, infant formulae, complementary foods for infants and young children, foods nutrient supplementation, processed dietary fiber-based foods, and foods for special dietary uses. The major differences between the special dietary uses. The major difference between the special nutritional foods and the other processed foods is that the special nutritional foods are characterized by their dietary uses for specific population groups rather than food ingredients or manufacturing and processing techniques which characterize and distinguish most of other processed foods. Although several countries establish similar standards for this type of foods, they use different legal names such as foods for special dietary uses(U.S.A., CODEX, Japan), foodstuffs intended for particular nutritional uses(EC), or special purpose foods(Australia). In addition, there are some other differences in the definitions for these food types and categorization of food types among countries. The major difference in the definitions is the description of 'special dietary uses' by specifying certain population groups whose nutrient requirements are different from those of ordinary men due to physiological or physical conditions and therefore may not be sufficiently met by consuming ordinary foods. The categorization of this type of foods is based on the type of dietary uses in the other countries, whereas we include foods simply supplemented with nutrients or foods having certain components such as dietary fibers even if these foods types do not have special dietary sues. Recently, a revision of standards for special nutritional food has been proposed. However, the description of 'special dietary uses' is not clearly indicated in the definition, and some food types which should not be categorized into the special nutritional foods still remain in this category. In order to correct these problems, the standard of food labeling in the Food Safety Law needs to be revised along with revision of food standards in the Food Code.

  • Objective: The goal of this study was to explore the implementation status of positive behavior support(PBS) for child care and education teachers and special education teachers at inclusive settings, and to investigate support needs of both teachers for improving the implementation of PBS. Methods: This study made up 405 surveys for child care and education teachers and special education teachers in 45 inclusive settings from July to August in 2019. A total of 244 surveys(60.2%) were completed and returned. Results: Special education teachers were statistically higher than child care and education teachers in the implementation of the center based level 1, the small group based level 2, and the individual based level 3 of PBS. In open-ended responses, when implementing PBS, the two groups of teachers had difficulties in getting knowledge about how to instruct preschoolers and implementing PBS. Both groups of teachers wanted the education and the training opportunities for PBS at first, and to 'reduce the teacher-to-child ratio'in the public support system. Conclusion/Implications: Based on the results, suggestions were discussed on how to improve the implementations of PBS of child care and education teachers and special education teachers at inclusive settings.

  • Background: Patients with special health care needs are more likely to develop health problems, including dental problems. Dental treatments require a good level of communication with the patient. Therefore, in these patients, sedation and general anesthesia are an extremely humanistic approach for comfortable and successful treatment. In patients with special needs, there is no standard anesthetic approach due to varying clinical conditions. The aim of this study was to provide literature content about the anesthetic approaches used by us in patients with special needs. Methods: The medical records of 710 patients with special health care needs treated under general anesthesia or sedation were reviewed retrospectively. Demographic data, the American Society of Anesthesiologists classification, Mallampati score, anesthesia duration, anesthesia type, anesthetic and analgesic agents used, dental treatment performed, secondary diseases, and complications in the perioperative period were recorded. Patients were evaluated under five groups: Down syndrome, other syndromes, psychiatric disorders, physical disabilities, and complicated medical story. Results: Among the patients evaluated, 47.5% were females and 52.5% were males (mean age $15.76{\pm}11.17$ years), and general anesthesia and sedation were administered in 72.9% and 22.1% patients, respectively. The mean duration of anesthesia was $43.20{\pm}35.85$ min. Simple dental treatments were performed in all groups, and the most common complications were observed in the other syndromes group. Conclusion: Complications can be reduced by utilizing the appropriate anesthetic approach and taking serious precautions in patients with special needs.

  • This study concentrates on investigating teaching methods with which students of a commercial high school, located in a rural district, can improve their attitude toward mathematics. To begin with, this study examines the causes which make the students take negative views against it through a survey of their current attitude toward mathematics; offers a special class for them to develop a positive attitude toward it: and then, figure out how much they change their academic attitude within the class and how much they improve their academic achievement as well. The results can be summarized as follows: First, the experimental groups showed terribly negative attitudes toward mathematics, and their academic achievements were very low compared with students of academic high schools nearby, Second, thanks to the special class given to improve their attitude toward mathematics, the experimental groups ended up taking a meaningful positive attitude toward it and developing their academic achievements in the subject. On the other hand, the controlled groups without any chance to receive special lessons remained unchanged. Therefore, it is indicated that a special lesson, properly provided, would play an important role to improve students' positive attitude toward mathematics and develop their basic academic achievements.

  • The graying of populations is emerging as an international issue around the world, and this is a problem that is rapidly advancing in Korea as well, signaling the need for financial preparations for the aged. For this purpose, various retirement pension systems are being employed as preparatory measures for the nation's elderly. Using data from 1474 people in the 2007 panel study of National Security for the Retired, the present work attempts to look at satisfaction rates with regard to public pension receipts for the national pension and special occupational pensions according to general characteristics and factors related to the preparation for an aging society. Satisfaction with retirement pension receipts according to the type of pension was high for special occupation retirement pensions, individual retirement pensions and the national retirement pension, in that order. Looking at satisfaction rates based on the general characteristics of pension recipients, the study revealed that for the national pension, satisfaction was highest for groups with above-average physical and psychological health, groups who think appropriate living expenses for the elderly are lower, groups in which a partner also earns income, and groups who had amply prepared for their expected living expenses in later life. Regarding special occupation retirement pensions, satisfaction was high for groups over the age of 70, groups with good psychological health, and groups sufficiently prepared for their living expenses in later expenses, compared to groups for which these factors did not apply. In terms of the relative influences impacting retirement pension recipient satisfaction, satisfaction with the national pension was highest when the primary source to cover elderly living expenses was a resource other than income earned by the recipient and their partner and/or income received from children. Concerning special occupation retirement pensions, satisfaction was highest among those whose education terminated before middle school, and for those in good physical health. Based on the above results, it is vital that plans exist for preparing sufficiently for the living expenses of the elderly and for facilitating the physical and psychological health of pension recipients. Plans are also necessary to, ensure that citizens are provided with easily accessible educational programs and activities regarding general installment savings and deposits, stocks and bonds, real estate investments, individual retirement pensions, private insurance, severance pay pensions, and public pensions.

  • Objective: This experiment was conducted to investigate the effects of chromium picolinate (CrP) on fat deposition, genetic expression and enzymatic activity of lipid metabolism-related enzymes. Methods: Two hundred forty one-day-old Ross broilers were randomly divided into 5 groups with 4 replicates per group and 12 Ross broiler chicks per replicate. The normal control group was fed a basal diet, and the other groups fed the same basal diet supplemented with 0.1, 0.2, 0.4, and 0.8 mg/kg CrP respectively. The experiment lasted for 21 days. Results: Added CrP in the basal diet decreased the abdominal fat, had no effects on subcutaneous fat thickness and inter-muscular fat width; 0.2 mg/kg CrP significantly decreased the fatty acid synthase (FAS) enzymatic (p<0.05); acetyl-CoA carboxylase (ACC) enzymatic activity decreased in all CrP groups (p<0.05); hormone-sensitive lipase (HSL) enzymatic activity also decreased, but the change was not significant (p>0.05); 0.4 mg/kg CrP group significantly decreased the lipoprotein lipase (LPL) enzymatic activity. FAS mRNA expression increased in all experimental groups, and the LPL mRNA expression significantly increased in all experimental groups (p<0.05), but not 0.2 mg/kg CrP group. Conclusion: The results indicated that adding CrP in basal diet decreased the abdominal fat percentage, had no effects on subcutaneous fat thickness and inter-muscular fat width, decreased the enzymatic activity of FAS, ACC, LPL and HSL and increased the genetic expression levels of FAS and LPL.
