  • A type certificate is required to ensure the safety of aircraft design. If a person is to pursue major design change to the certified aircraft, an applicant has to apply for a new type certificate, an amended type certificate, or a supplemental type certificate appropriately. Design changes to be applied for a supplemental type certificate are abstractly defined in ICAO, FAA, and EASA regulations. In this paper, authors reviewed certification procedures regarding design changes, analysed certification examples of leading countries, and presented the criteria to determine "major design changes not extensive" for a supplemental type certificate.

  • There is currently no satisfactory way to optimize supplemental lighting in a greenhouse-type plant factory especially concerning plant production. In a commercial plant factory, we got outside radiation data, inside radiation data and lamp running data. They have a correlation, but have much disorder. By using regression, tendency between the outside and the inside including supplemental lighting was found. We could estimate the average transmittance of this plant factory. From this estimation, we could admit the amount of inside radiation was supplied as much supplied compared to natural radiation. Then we are trying to investigate of the production amount and the supplemental lighting. Plant factory is environmentally controlled, the temperature and humidity are not actually controlled stable. We propose a design of neural network model could be useful to estimate the profit resulting from the operation of supplemental lighting.

  • The aim of this study was to assess the nutrient intakes from infant formula and supplemental foods of 246 healthy infants fed infant formula, aged from 5 to 18 months. Subjects were devided into two groups depending on supplemental food type for weaning, Domestic supplemental foods (mainly home-made, n = 129) and Delivery supplemental foods (mainly commercially-delivered, n = 117). Four subgroups were assigned to 5-6 months, 7-8 months, 9-11 months, and 12-18 months by ages, respectively. Dietary assessment was carried out using 24-hour-recall method. Formula intakes in the delivery group tended to decrease accordingly with the ages. However, in the domestic group, formula intakes up to 8 months were similar and decreased after 9 month. Energy, protein, calcium and iron intakes from infant formula and supplemental foods were assessed. Energy intake at 12-18 months were lower than the RDA in both groups. Daily intake of protein and calcium at all ages were much higher than the RDA in both groups. Therefore, protein and calcium overnutrition were elucidated. Especially, protein intake at 5-6 months, calcium intake at all ages from infant formula was higher than the RDA in both groups. Iron intake at 5-6 months from infant formula were higher than the RDA. Consequently, as for infant formula, it was suggested that not only formula intakes but also nutrient content in formula should be reconsidered. On the other hand, nutrient intakes from supplemental foods in the domestic group tended to be higher than that of the delivery group. Especially at 9-11 months, significant differences between the two groups were observed. This may be due to high dependency on commercial powdered baby food in the domestic group. This study revealed that daily nutrient intakes of formula-fed infants are desirable but nutrient intakes from infant formula are too high. Conclusively, this study suggests that as the age of infants increases, formula intakes should be controlled and various supplemental foods besides commercially powdered baby food should be appropriately provided.

  • The surveys of food intakes were carried out on 49 healthy infants aged 4-9 months at the first interview and repeated 3 more times at the interval of 2 months by using food diary recorded by their mothers. Of the subjects 12 were breast-fed, 28, formula-fed, and 9, mixed type-fed. Foods introduced first as the weaning food were commercial weaning foods, fruit juices, yoghurt, egg and rice. Supplemental food was introduced at the age of 4 months in 57% of the infants, but it amounted to a significant proportion of overall food consumption from the age of 6 months. The levels of nutrients except energy, iron and niacin were similar or in excess of RDA, and breast-fed infants tended to have lower intakes of energy and protein compared to infants formula-fed or mixed type-fed. Average intakes of vitamin A, vitamin B1, vitamin B2, vitamin C and calcium were above RDA, but iron intake did not meet RDA of infants of all ages. In conclusion, the average status of nutrient intakes of infants was fairly good, however, food consumption besides milk was less in breast-fed infants than in formula-fed infants, and iron status seemed to be poor, Although it is well-known that breast-milk compared to formulas is more beneficial for infants, mothers feeding breast-milk to their infants should be educated for the importance of supplemental food and its practice to support good nutrition.

  • This experiment was conducted to investigate the effect of the supplemental Bamboo vinegar on production and meat quality of broiler ducks for 35 days. One hundred broiler ducks were divided into 4 groups of 25 ducks. Dietary levels of bamboo vinegar 0%, 1%, 2% and 4% were added to experimental diets ot each of the groups. The wei핌t gain and feed intake of ducks f3d with supplemental bamboo vinegar significantly high compared to those of the control. The carcass rate of the ducks fed with supplemental Bamboo vinegar 1% and 2% were increased compared to that of control, but the ducks fed with 4% treatment was decreased in carcass rate. The lipid and cholesterol content of breast meat of the ducks f3d bamboo vinegar 2% and 4% were significantly decreased (P<0.05). The color values in redness and yellowness were increased by supplemental Bamboo vinegar. Palmitic acid of fatty acid composition in breast meat was decreased by supplemental bamboo vinegar groups, whereas linoleic acid was increased, this difference was especially observed in supplemental Bamboo vinegar 2% (P<0.05). The odor, appearance and taste of sensory evaluation were improved by supplemental bamboo vinegar, especially in supplemental bamboo vinegar 1% and 2% (P<0.05). The results of this study indicate that the supplemental bamboo vinegar 1% and 2% may improve the production and meat quality of broiler ducks.

  • Experiments were conducted to evaluate the nutritive values of supplemental L-lysine, liquid and powder type, and DL-methionine in weanling pigs. For feeding trial, 165 weanling pigs were treated in 2 controls; 18 and 16% CP, 6 supplementations of lysine alone to 16% CP diets; 0.1, 0.2 and 0.4% of liquid and powder type each, and 3 supplementations of lysine + methionine to 15% CP diets; 0.05 + 0.025, 0.1 + 0.05 and 0.2 + 0.1%. Pigs were fed for 5 week to investigate the protein sparing effect of supplemental amino acid, and the optimal supplemental level. A metabolic trial included the measurements of digestibilities of dry matter, crude protein, crude fat, crude fiber, energy, phosphorus and amino acids. The liver acinar cell culture was conducted for the protein synthesis activity of the pigs fed each experimental diet. Supplementation of both type of L-lysine in 16% CP diet showed improved daily weight gain and feed efficiency which were compatible with those of pigs fed 18% CP diet. Groups fed liquid lysine did not differ from those fed powder type in growth performance. Supplementation of lysine and methionine to 15% CP diet did not improve growth performance of pigs to the extent that 18% CP diet was fed. In nutrient digestibility, 16% CP control diet showed significantly (p < 0.05) lower crude protein digestibility than any other treatments. Digestibilities of 16% CP diets with lysine supplementation were equal to that of 18% CP control, while digestibilities of 15% CP diets with the supplementation of lysine + methionine was inferior to that of 18% CP control. Supplementation of lysine alone reduced the nitrogen excretion compared to the none supplemented control groups. However, addition of lysine + methionine excreted more nitrogen than controls. Pigs fed diet supplemented with lysine alone, or lysine + methionine excreted less fecal phosphorus than those fed none supplemetation. Retained protein from liver tissue of pigs fed 18% diet was significantly (p < 0.05) greater than those fed 16% CP diet. A significant difference (p < 0.05) was observed in physical type of lysine. Feeding of powder type showed less secreted protein and greater retained protein in the culture of liver acinar cell. It is concluded that supplementation of lysine at the level of 0.1 to 0.2% can spare 2% of dietary protein and reduce nitrogen excretion by 19.3%. Also, no difference in nutritional values was observed between liquid and powder lysine in weanling pigs.

  • The system needs to be modified to improve the performance of the aircraft in operation or to satisfy the requirements of related laws. Appropriate standards are required for the technical skills for remodeling the aircraft system, design verification for airworthiness of the aircraft, and supplemental type certification (STC) certification procedures for type certification. This study analyzes the current status and demand of domestic aircraft remodeling, examines the current supplementary type certification procedure, and diagnoses the problem. In addition, as a result of researching measures to improve remodeling technology and certification capabilities to extend the life of the aircraft, improvements in the education system were derived to improve the domestic additional type certification process, such as approval of remodeling agencies and appointment of qualifications for each professional technician.

  • Experiments were conducted with chicks and pigs to determine whether the sparing effects of cobalt (Co) or nickel (Ni) on zinc (Zn) nutrition were due to an improved Zn availability. They included a Zn balance study with New Hampshire X Leghorn cross chicks, a $^{65}Zn$ absorption study with Ancona chicks and a $^{65}Zn$ balance study with pigs. The basal diet was a corn-soybean type diet high in calcium. In the Zn balance study with New Hampshire X Leghorn cross chicks, Zn retention percentages for basal, + 54 ppm Ni or + 54 ppm Co were 39.4, 40.4 and 48.3, respectively. In the $^{65}Zn$ absorption study with chicks, adding these levels of Ni or Co to the basal diet increased $^{65}Zn$ absorption from 12.8% to 14.0% and 15.1%, respectively. Supplemental Ni and Co increased the proportion of body $^{65}Zn$ found in liver and bone. With the pig experiment, $^{65}Zn$ retention percentages for basal, +54 ppm Co and + 60 ppm Zn groups were 20.0, 26.7 and 12.2, respectively; while Zn retention values (mg) in the body were 29.5, 45.1 and 60.5, respectively. In addition, supplemental Co increased $^{65}Zn$ concentration in the blood, liver, kidney and duodenum. These studies showed that supplementation of the basal diet with Co resulted in increased absorption of dietary Zn in chicks and pigs. The effect of Ni in chicks was less than that of Co. The ability of supplemental Co and to a lesser extent of Ni to improve weight gain as well as reduce other Zn-deficient signs in both species fed a practical corn-soybean type diet high in in calcium can be explained, at least in part by an associated increase in Zn absorption. The possible mechanism involved in these effects are discussed.

  • Two inorganic (zinc sulfate and zinc oxide) and three organic (zinc acetate, zinc-methionine, and zinc-lysine) zinc sources were evaluated for their effects on the performance and carcass characteristics of broiler chicks. The birds were randomly assigned to one control (non-supplemented) and 15 treatment (supplemented) groups consisting of four replicates of 10 chicks each in a $5{\times}3$ factorial arrangement of treatments (five zinc sources and three supplemental zinc levels). Birds were kept in floor pens in a temperature-controlled room from 1 to 42 d of age and fed a non-supplemented basal diet (control) or the basal diet supplemented with 40, 80 or 120 mg/kg of Zn as mentioned sources. Dietary zinc source had considerable effect on feed intake in all experimental periods. Increasing Zn level from 80 to 120 mg/kg decreased the average feed intake in the growth stage (p<0.01) and also in the entire experimental period (p<0.001). Similarly, the average daily gain during the entire trial period was affected by the type of Zn source (p<0.001) and supplemental level (p<0.01). One degree of freedom contrast comparisons showed that the inclusion of organic zinc sources into the diets caused significant increases in feed intake and body gain when compared with inorganic counterparts. Except in wk 1, dietary supplementation with organic sources improved (p<0.05) feed conversion ratio; FCR values were not affected by dietary Zn source or supplementation level. Breast meat yield increased with supplemental levels of organic Zn sources; however, other carcass parameters were not affected by dietary Zn source. On the other hand, organic versus inorganic zinc supplementation caused a significant increase in liver, breast and carcass weight percentages. The present findings suggest that supplemental levels of organic Zn compounds had beneficial effects on broiler performance, and Zn requirements can be reduced using these feed supplements in poultry rations.

  • The purpose of this study is to understand and analyze characteristics of using pattern on the physical facilities and fundamental demands about improving factors associated with management of variation type. The teachers of four middle schools are participated through questionnaires with this survey. According to the results, supplemental factors of learning activities, convenient facilities for students, factors with space utilization, moving class and arrangement of similar subject blocks are influential in order on the awareness of teachers for correspondence of variation type. In the analysis of variance based on the sampling factors, significant differences were shown in the factors of attached group, gender, age and managemental experience of variation type. Especially, the factors with moving class and convenient facilities for students are analytically more differential than the other factors, therefore, these factors must be considered in detail.
