Objective: This study aims explore the experiences of consulting in childcare centers and identify policy implications through focus groups consisting of childcare personnel, including directors, teachers, consultants, and program staff. Methods: Focus group interviews were conducted with participants divided into three distinct groups. The interviews, held via Zoom, used an open-ended discussion format based on pre-announced topics. The collected data were then systematically categorized and classified into themes. Results: Since the primary purpose of consulting was to meet the requirements of the childcare evaluation system, expanding the scope of consulting is necessary to invigorate these programs. Additionally, the voluntary participation of childcare teachers and their positive relationships with consultants were identified as key success factors. Emphasizing the need to enhance consultants' expertise and address regional disparities was also highlighted. Conclusion/Implications: This study suggests that it is essential to systematize and diversify the consulting field, as well as enhance the expertise of consultants, to establish consulting as an effective method for improving the quality of childcare centers.

According to economical status, malnutrition and overnutrition coexist among preschool children in Korea. Malnutrition have been a serious problem for children in some of rural. Many children have deficiencies of some nutrients such as riboflavin A, and simultaneously they have overcaloric intakes with empty calorie foods. Preschool children have nutritional problems which can affect the growth and development. To investigate whether nutritional intakes can influence on the growth or not, nutritional intakes and anthropometric measurements were determined for infants aged 4~6 years old in three different kinds of preschools. Daily nutrient intakes were calculated by the combination of a direct measurement and 24 hour recall, and the diet consumption patterns were determined by diet quality index. Overall growth of infants in Cheonan area was under the normal growth in Korea. Preschool children in orphanage consumed almost all nutrients much less than the recommended daily allowances, on the other hands, children in private preschool had over-intakes of nutrients when it is compared with the daily requirements. However, the scores of the diet quality index were similar in three preschools since children in private preschool consumed more fat and junk food than those in orphanage. The weight and height of preschool children in orphanage was lower than those in private preschools. This was due to the lower consumption of the important nutrients in infants in orphanage. The consumption of all nutrients except fat did not show any correlation with height or weight. The quality index of fat, cholesterol, grains and protein intakes was higher in children in private preschool than in orphanage. In conclusions, 1)the private preschool children had worse nutrient intake patterns. Better consumption of vitamin $B_2$, calcium and grains were, bigger height and chest circumferences children obtained. 2)Since most of energy intake of preschool children came from junk foods, they needed to consume more supplementation of vitamins and minerals, which is necessary for normal growth. 3)It is desirable for the children to cut down junk foods and empty calorie foods.

Military rotary aircraft are heavily exposed to projectile environments due to their mission characteristics, and fires caused by fuel leaks after shooting are linked directly to the loss of human life. To improve the survivability of pilots and crews, the fuel tank in rotary aircraft must have gunfire resistance and anti-explosion characteristics. Gunfire resistance can be satisfied by applying a self-sealing cell to a fuel tank. Anti-explosion can be satisfied by reducing the oxygen concentration in an explosive area and suppressing the generation of combustible fuel vapor by minimizing the evaporation rate of the fuel by heat. A Korean utility helicopter applies anon-board inert gas generation system to meet the anti-explosion requirements for ballistic impact. The generator fills the fuel tank with an inert gas and reduces the oxygen concentration. This paper describes the overall development process of the OBIGGS developed in accordance with the localization process of weapon components. OBIGGS was developed/manufactured through domestic technology, and the performance was found to be equal to or better than that of the existing products through single performance tests and aircraft mounting tests.

Background: Studies of quality of life (QoL) of oncological patients is carried out using questionnaires approved in many international clinical studies. The European Organization for Research and Treatment of Cancer EORTC QLQ-C30 (Quality of Life Questionnary-Core 30) and its special brain cancer module EORTC QLQ-BN20 are widely used in the world neurooncologic practice. They are available in more than 80 official versions of 30 languages of the world. Previously we used the official versions in Russian, which often causes difficulty in understanding for native Kazakh language speakers, who comprise more than 60% of our respondents. This was the reason for creating a version of Kazakh language. Therefore, in 2014 for the first time the process of adaptation of questionnaires to the Kazakh language was initiated. Materials and Methods: The translation process of questionnaires to Kazakh language was held in accordance with the requirements of the European Organization for Research and Treatment of Cancer EORTC on QoL and consisted of the following stages: preparation - translation - pilot testing - approval. The official permission of authors and "Guideline on translation" was obtained which was developed by the working group of the EORTC on QoL. The pilot testing of EORTC QLQ-C30 and QLQ-BN20 questionnaires was conducted on the basis of the Department of Central Nervous System Pathology of the "National Centre for Neurosurgery" in patients with malignant tumors of the central nervous system. Results: The official versions of the EORTC QLQ-C30 and QLQ-BN20 questionnaires in Kazakh language were introduced and adapted in practical neurosurgical operations in Kazakhstan. Conclusions: The approved versions of the questionnaires in Kazakh language are now available for mainstream use on the official website EORTC.com. The versions of these questionnaires can be used in domestic cohort studies and clinical practice in the Republic of Kazakhstan. The use of these tools for assessing QoL will help professionals in the planning of individual treatment strategies and selection of the necessary therapy.

The aim of the present study was to assess the effects of skipping breakfast on diet quality and metabolic disease risk factors in healthy Korean adults. Subjects included 415 employees (118 men, 297 women; 30-50 years old) of Jaesang Hospital in Korea and their acquaintances. Data collected from each subject included anthropometric measurements, 3-day dietary intake, blood pressure, and blood analyses. The subjects were classified into three groups based on the number of days they skipped breakfast: 'Regular breakfast eater', 'Often breakfast eater', or 'Rare breakfast eater'. Participants in the 'Rare breakfast eater' group consumed less rice, potatoes, kimchi, vegetables, fish and shellfish, milk and dairy products, and sweets than did participants in the other two groups (P for trend <0.05) and ate more cookies, cakes, and meat for dinner (P for trend <0.05). Participants in the 'Rare breakfast eater' group consumed less daily energy, fat, dietary fiber, calcium, and potassium than did participants in the other groups (P for trend <0.05). The percent energy from carbohydrates was lower and fat intake was higher in the 'Rare breakfast eater' group than in the other groups (P for trend <0.01). When diets were compared using the Acceptable Macronutrient Distribution Range for Koreans, 59.1% of subjects in the 'Rare breakfast eater' group consumed more energy from fat compared with the other two groups (P <0.005). According to the Estimated Average Requirements for Koreans, intake of selected nutrients was lower in the 'Rare breakfast eater' group than in the other two groups (P <0.05). The risk of elevated serum triglycerides was decreased in the 'Rare breakfast eater' group (OR, 0.3 [0.1-1.0], P for trend=0.0232). We conclude that eating breakfast regularly enhances diet quality, but may increase the risk of elevated serum triglycerides.

This study concerns the transmission of energy and data using induced electromotive force. Due to the requirements of weapon systems, most arms are kept in an armory for a very long time before being used. During this time, the reserve battery, which serves mostly as a power supply for the electronic fuze, can be degraded, thus causing problems when it is actually needed. We attempt to solve the various problems associated with the old fuze system caused by long-term storage by using the 'induction power' transmitted from another device just before its operation, instead of using 'built-in power'. We tried to find the best carrier frequency to communicate with the system by induced electromotive force. Also, we changed the communication method for transmitting the 'induction power' from 'FM/AM modulation' to 'Duty ratio modulation', which can transmit a large amount of data in a short time. Through experiments, it was demonstrated that the induction coil can replace the reserve fuze's battery without any problem, thus confirming the possibility of using an induction coil as the power supply source of the electronic fuze.

Newly published IEC 60601-1-3 ; 2008 2nd Edition has two important meanings. First, Radiation Quality and Dose should make sure for safety of patient and staff in manufacturing diagnostic X-ray equipment. Second, it should be minimized of Leakage Radiation, Residual Radiation, and Stray Radiation. The requirement to make enactment or revision of national standard for diagnostic X-ray Equipment is as follows : 1. It should be adjusted the new standard to the recent IEC Publication under the consideration of the Korea medical circumstances. 2. For focus to the Radiation Safety, IEC 60601-1-3 (General requirements for radiation protection in diagnostic X-ray equipment) could be applied to the new regulation. It should be compact sentence. 3. A sudden Notification change should not be desired. It needs a enough time to make easy the circumstances.

The objective of this study was to investigate the quality characteristics and antioxidant activities of aronia jam prepared with different content of mashed apple. To analyze the quality characteristics pH, texture, color, antioxidant activity, total polyphenol content, and sensory property were investigated. As aronia amounts decreased, the pH of aronia jam level increased from 3.97 to 4.40, while its total acidity decreased from 0.39 to 0.27. In color, the L-, a-, and b- values increased with decreases in aronia contents when compared with 100% aroma jam. Texture evaluation revealed that the hardness, springiness, gumminess, and chewiness of 100% aronia jam were markedly higher than those of the control and other samples (p<0.05). As the aronia content decreased, both the antioxidant activity and total polyphenol content significantly decreased (p<0.05) and the total anthocyanin content gradually decreased. In the sensory evaluation, the jams containing 50% and 70% aronia showed higher values than those of other samples in overall acceptability. Taken together, aronia jam with 30% apple could be the best in order to meet the taste and functional requirements for consumers.

Objectives : Functional dyspepsia is a prevalent disease. It impedes subjective quality of life. The purpose of this research is to examine the effect of acupuncture treatment for functional dyspepsia. Methods : In this randomized, single blind, placebo-controlled study, we compared active acupuncture with sham acupuncture for the treatment of functional dyspepsia. Volunteers who satisfied the requirements were enrolled in study. Severity of dyspepsia was measured by Nepean Dyspepsia Index(NDI) and Functional Dyspepsia Quality fo Life(FD-QOL) before and after treatments. Results : 68 subjects finished study. There were not difference between two groups on age, sex, weight, height, severity of dyspepsia, subtype, Byeonjeung, surmise of treatment. After treatment total key symptoms score, improve rate of key symptoms were decreased than before treatment in active acupuncture group, but there were no statistical significance compared with sham acupuncture group. After treatment "pressure in upper abdomen" and " cramps in upper abdomen" were more decreased in active acupuncture group compared with sham acupuncture group(p=0.001, p=0.014). After treatment total symptom score and QOL of NDI were decreased than before treatment in active acupuncture group, but there were no statistical significance compared with sham acupuncture group. After treatment eating status of FD-QOL in active acupuncture group was significantly increased than sham acupuncture group(p=0.008). After treatment liveliness status of FD-QOL and total score of FDQOL in active acupuncture group was increased than sham acupuncture group though statistically insignificant(p=0.095, p=0.077). Conclusion : Acupuncture treatment is effective to improve the symptoms and quality of life in patients with functional dyspepsia.

To ensure safety of raw materials for military foods, hazard assessment and monitoring of residual pesticides was conducted on agricultural products consumed by 9 companies based in Gyeongin and Gangwon. Residual pesticides were analyzed for 142 different products, by applying the multi-species pesticide polycomponent analysis method. Of the 36 samples analyzed, residual pesticides were detected in 7 samples, representing a detection rate of 19.4%. One particular pesticide residue was detected in peanuts, green onions, and red pepper powder, and 20 types of pesticide residues were detected in red pepper powder used in combat foods. However, all residues were found to be below the permissible level. Moreover, the hazard assessment results for Cypermethrin, Tebuconazole and EPN showed the highest concentration among the residual pesticides detected. Since the estimated intake was less than 100% as compared to the ingestion limit, it was considered to be safe. I have suggested the edit as per my understanding. Please review for accuracy, and revise appropriately if required. This is the first pesticide Risk Assessment study encompassing military requirements. Considering the results, we expect further application research, including research on reducing hazardous materials.
