This study was conducted in order to investigate the association between picky eating behaviors of preschool children and growth outcomes. In this study, picky eating behaviors were defined as containing four constructs of 'eating a small amount (ES),' 'neophoic behavior (NB),' 'refusal of specific food groups (RF),' and 'preference for specific food-preparation methods (PP).' A 7-point scale was used for the multi-item questionnaire, which consisted of 21 items (three items for ES, two items for NB, nine items for RF, and seven items for PP), in order to evaluate picky eating behaviors of children. Subjects were recruited among visitors at a medical clinic in Seoul. A total of 150 self-administered survey responses from parents of preschool children were analyzed in order to investigate the association between picky eating behaviors of preschool children and growth outcomes. Height for age (HFA) and weight for height (WFH) z-scores were used for assessment of preschool children's growth. The prevalence of ES, NB, RF, and PP was 44%, 57%, 73%, and 53%, respectively. Children with ES had lower HFA (p < 0.05) and WFH (p < 0.0001) than those without ES, while children with NB, RF, or PP had HFA and WFH were similar to their counterparts. The mean HFA z-score of children with ES was less than 0 (p < 0.05) and the mean WFH z-scores of children with ES, NB, RF, or PP were less than 0 (p < 0.05). According to the study results, related growth outcome differed depending on constructs of picky eating behaviors. In particular, picky eating of ES showed a risk of faltering height growth in preschool children. Further comprehensive studies on the reason for ES and intervention approach is warranted.
It is possible to use pallet for forwarding as chinese cabbages and radishes are general large-scale trading items at the agricultural wholesale market though, however, most of these are forwarded as it have packed in net bags or in P·E bags. Thus, it is still hard for palletizing. The type of packing the product in the net bag makes it difficult for palletizing. It is not a stable shape enough and easily collapsed for pallet loading. Because of this collapsibility, the corrugated cardboard box is being used to enhance forwarding efficiency, but the existing corrugated cardboard box could be crushed easily by moist what is from the agricultural product's property and it also could be squashed by the mass of the loaded box layers on itself. In contrary, the functional waterproof corrugated cardboard box is not collapsed through palletizing and it is efficient for product management with it's ventilation function in respond to pre-cooling effect. Furthermore, because it has various functional shapes as the open type, the partition type and so on, it is effective for maintaining freshness of the product and standardizing the distribution of agricultural product. It is well-known that it is possible to introduce this box to cargo-works of agricultural product. Consequently, the recognition of main distributors about the pallet distribution of the chinese cabbage and the radish was apprehended in this study for activating mechanization of loading and unloading. The survey was conducted to the main distributors such as the forwarder, the auction dealer and the commission merchant with Garak-dong wholesale market as the center. The appropriate packing materials and problems of the existing method for loading and unloading were derived through the survey. Especially, it was focused on analyzing the difference of recognition between the subject groups for the way of using waterproof cardboard corrugated box to deal with the difficult product for packing in normal corrugated box because of the box's absorption of moist from the agricultural product like a chinese cabbage and a radish. Total In the cases of the forwarders and the commission merchants, the net was highly responded as 45%, 74% from each groups for the best packing material for mechanization of distribution and the waterproof corrugated cardboard box was responded as 20%, 22% from each groups as much preferable than multi-stage wooden box. However, for the radish, the waterproof corrugated cardboard box was the best material as 56%, and the auction trader group supported it for 80%. So, the using the waterproof corrugated cardboard box for mechanization of distribution was negative for the chinese cabbage, but it was positive for the radish. The average was 2.42, the standard deviation was 1.24. The negative response(about 55%) was prevailing more than positive response(about 23%). It could be analyzed that even there was the positive recognition for using the waterproof corrugated cardboard box for the radish though the preference for low price of net bag in the chinese cabbage forwarding procedure. Still now, it seems that is a burden for using the waterproof corrugated cardboard box with high price. In the analysis on the recognition differences about using the waterproof corrugated cardboard box for the chinese cabbages and the radish between the forwarders and the commission merchants, generally the negative recognition was prevailing, but the forwarders(2.696) were more positive for using the waterproof corrugated cardboard box than the commission merchants(2.145).

To assess trans fatty acids (tFAs) intake of a girls' high school students in Pusan, dietary history and quantitative food frequency questionnaire (FFQ) were surveyed and analyzed with a total subjects of 274, 268 in summer and winter respectively. It was shown that 38.0% of subjects which was the highest percentage, had snack twice a day in frequency of snack intake. The most favorite snack of subjects was ice cream (46.4%), the preference for milk and dairy products was considerably high. 43.4% of subjects responded to once a month in frequency of dining out. They preferred grilled pork (39.1%), hamburger (36.9%), grilled beef (26.6%) in order. It was also appeared that they preferred fast food. In the case of eating bread, 8.0% of subjects ate bread and margarine, 7.1% butter. Generally, the subjects preferred margarine to butter. tFAs intake for each person per day was $4.24{\pm}0.18\;g$. There was significant difference in tFAs intake according to parents income (p<0.05), frequency of snack intake (p<0.001) and that of dining out (p<0.05). tFAs intake produced naturally (N-tFAs) was $0.86{\pm}0.00\;g$ which corresponded to 20.3% of total tFAs intake per day. tFAs intake produced artificially (H-tFAs) in the process of hardening oil was $3.38{\pm}0.14\;g$, equaled to 79.7% of total tFAs intake per day. There was significant difference between H-tFAs intake for each person per day (p=0.000)

Kyejang is a Korean traditional beverage manufactured from medicinal plants and fruits using honey, sugar, or starch in cold water. In this study, cinnamon-containing kyejang, which is a type of beverage Jang, was reproduced based on Imwonsibyukji's method published in 1827 in the Korean literature. Kyejang made by nuruk, cinnamon, and medicinal plants was prepared at various temperatures and periods. Kyejang was assayed for physiochemical properties (pH and acidity), contents of metabolites (organic acids, sugars, and amino acids), and sensory characteristics (aroma and taste). During fermentation, content of organic acids (e.g. lactic acid, acetic acid, and shikimic acid) increased, which lowered pH, increased acidity, and increased intensity of sour taste. In the case of free sugars, fructose and maltose levels decreased while glucose and mannitol levels increased during fermentation periods, and sweetness decreased. The main amino acid in kyejang was tryptophan, followed by asparagine, proline, and arginine. The sensory evaluation score of overall preference was highest for kyejang which was fermented at $20^{\circ}C$ for 3 days. The results will be provide the basic data of fermentation conditions for standardized manufacturing process of kyejang.
This study carried out on the manufacturing of pidan. The production of pidan can be one of solutions for over-produced eggs and stable egg price. For the alkali-pickling solution for manufacturing of Pidan, the tested concentration of NaOH and NaCl were respectively as 3, 5, 7% and 5, 10, 15, 20%, and examined every 2 days for 14days. According to the results, pH value of alkali-pickling solution was increased by the increment of NaOH concentration and the pickling period, and was decreased by the increment of NaCl concentration. The pH value of egg yolk was increased by the increment of NaOH concentration, but it was not significantly different by the NaCl concentration. By the increment of NaOH and NaCl concentrations, the alkali infiltration in egg yolk and egg white was accelerated. Furthermore, the weight change of the eggs in the alkali-solution has no effects on manufacturing of Pidan. Liquefied albumen showed significant differences by NaOH concentration rather than that of NaCl. There was no liquefied albumen for 14days at 3% of NaOH, but it was found between 11-12days at 5% and 8-10days at 7%, respectively. The pH values of egg white when it was liquefied albumen were between 11.8 and 12.0. Pidan was made by heat treatment after 6-7days dipped in the solution at the concentration of 7%, about 10days at 5%, and 12-14days at 3% of NaOH, respectively. Although, the period of manufacturing of Pidan was saved by the increment of NaOH concentration, liquefied albumen was accelerated and the food preference was decreased by ammonia odor. Therefore, the suitable concentration of NaOH is between 3 and 5%, and that of NaCl is between 5 and 10% due to the effect of salinity by the soaking period. Through this study, optimal pickling solution and dipping time for manufacturing of Pidan was figured out, and also find out that it can save a time about 15days for manufacturing of Pidan.
The word, 'Naturalization(向化)' is an unfamiliar term for us; however, to us as citizens who live in a multicultural society, it is a word worthy of hearty appreciation even once. At the present Korean dictionary, it has been defined as the word related to those terms such as Enlightenment(敎化) which are used to explicate the governance through a virtue of moral excellence(德治主義) of Confucianism, and the word, 'Hyanghwa(向化)' itself has already included the meaning of Enlightenment(敎化). On many occasions, people who were dubbed the converts or the naturalized citizens(向化人) emigrated to Chosun because there were such substantial reasons as economic and political advantages, rather than living in a society for reasons to the governance through a virtue of moral excellence(德治主義). Therefore, to understand the converts or the Naturalized citizens(向化人) correctly, it shall be required to examine the cause which is the governance through a virtue of moral excellence together with the true realities which are economic and political advantages. The word, such as Hwangjoin(皇朝人) should be considered in order to understand the meaning of 'Naturalization(向化)'. Hwangjoin(皇朝人) were those displaced people who had been forced to leave the fallen Ming Dynasty, and they will be contrasted with the converts or Naturalized citizens(向化人) that were mainly composed of the Northern tribes or Japanese. Actually, Naturalized citizens(向化人) and Hwangjoin(皇朝人) had all emigrated to Chosun because of changes in international affairs, meanwhile, however, they were treated differently for the reason that they were 'Hwai'(華夷). If we dub Chosun 'Self'(我), Naturalized citizens(向化人) and Hwangjoin(皇朝人) are equally called as 'The Other persons'(他者). Can we say that Chosun had established the right relationship with Other persons(他者)? Judging from the facts that there was occurrence of convert or naturalization for the other persons, dubbed Naturalized citizens(向化人) and that there was another occurrence of emigrants, called Hwangjoin(皇朝人), it is evident that the Relationships between the two had not rightly established. Also, the names so called Naturalized citizens(向化人) and Hwangjoin(皇朝人) were not given according to the preference of the other person, but provided by Chosun one-sidedly. The reasons for occurrence of convert or naturalization for the other persons, dubbed Naturalized citizens(向化人) and for occurrence of other emigrants, called Hwangjoin(皇朝人) were ideology such as 'Hwai'(華夷). It is thought that the Relationships between 'Self'(我) and 'The Other Person'(他者) can be established only after excluding ideology.
In this study, antioxidant activity and quality characteristics of egg yolk mayonnaise and soy milk mayonnaise containing soybean paste powder were assessed. The mayonnaise with egg yolk as an emulsifier is E group according to the amount of soybean paste powder addition of 0% (E1), 3% (E2), 6% (E3) and mayonnaise with soy milk as an emulsifier is S group with soybean paste powder addition of 0% (S1), 3% (S2), 6% (S3). Total phenol content and electron donating ability of mayonnaise were increased as the amount of the soybean paste powder increased. L value of Hunter's color was decreased, but a value and b value were increased as the amount of the soybean paste powder increased. Soy milk mayonnaise showed very low cholesterol content than egg yolk mayonnaise. In sensory evaluation, S2 received the highest scores for flavor, overall taste and preference. Base on these results, soybean paste powder showed significant antioxidant activity in mayonnaise and cholesterol content was successfully decreased in soy milk mayonnaise compared to egg yolk mayonnaise. The soy milk mayonnaise with soybean paste powder will be a possible model to introduce our traditional food to the worldwide food item, such as mayonnaise.
This study was conducted to investigate the efficiency of water quality remediation and the inorganic ion removal characteristics by floating plant; water lettuce (Pistia stratiotes L.) in a batch reactor. Water lettuce can be used to remove N and P and other inorganic nutrients, by consuming them in the form of plant nutrient. The highest nutrient absorption of water lettuce was $112.5meL^{-1}\;N$ in Sonneveld-2S, $56.6meL^{-1}\;N$ in Sonneveld-1S, $31.8meL^{-1}\;N$ in sewage and P value was also the highest in Sonneveld-2S as $15.6meL^{-1}$ and in sewage as $5.0meL^{-1}$. These results indicated that using water lettuce held some promise in the context of purification of eutrophication. Also water lettuce had a preference for absorption N. Under Sonneveld-2S treatment, nitrogen percentage was the highest in plant tissue due to the highest concentration of nitrogen and removal by water lettuce. Under sewage, percentage of total N in both plant parts was high. Both above and underground parts, P percentage was less than N. It might be due to the fact that the absorption amount of P was less than N by water lettuce. It meaned that the ability of N removal by water lettuce was higher than that of P, relatively. In summary, these results show that the use of this plant was a viable option.
To discover the main characteristics of Korean traditional flower arrangement, they were compared with different articles and old paintings used in royal court ceremonies. The primary research involved principle of design. The times periods used were the Joseon Dynasty era of Korea, the Ming era of China, and the Edo eras of Japan. The result, which shows both the similarities and differences, of the research is summarized as follows. The similarities were that they all respect the features of nature, and their image expresses their creator's thinking. There was one technique, called 'Suje', in which a part of the stem is coming out from one branch. Also, each three eras preferred flowering trees and ornamental trees more than annuals or foliage plants. one of the differences was that korea used a simple number of materials. The work had volume and appeared mild by using a soft curved line which was repetitive and massive. The Joseon Dynasty era advanced a sense of beauty with artistic symmetry and balance. The work seemed soft and natural because of the little change in blank space, with almost no angle of line. The form had a characteristic preference of being taller than the typical Japanese arrangement. It appeared simple, calm, and rustic by using only one kind of material. In contrast, the Chinese style was gorgeous and displayed volume in a non-symmetrical tripodal form, which incorporated various colors and materials. Also, they avoided processing the materials in order to emphasize the original beauty of nature. Chinese flower arts did not become formalized because they did not consider the formality seriously the formal. The Japanese style was also gorgeous because it incorporated various materials and angles. It included an extreme technique in which an artificial line divided the blank space delicately. The line was both strong and delicate in an established form. The restriction of the main branch gave a light feeling, as well as more strain as in a balance sense. The Japanese eras emphasized more the use of line and a sense of blank space.
This study investigated the quality characteristics and antioxidant activities of morning bread containing various amounts of aronia sourdough starter. Morning breads were prepared with different volumes (0% (AS0), 15% (AS1), 25% (AS2), and 35% (AS3)) of aronia sourdough starter based on wheat flour. In AS3 group (35% added group), the specific volume and baking loss rate were the highest but the bread height was the lowest. When the aronia sourdough starter was added up to 25%, the expansion power, specific volume, and bread height were significantly increased (P<0.05). According to the added amount of sourdough starters, the lightness and yellowness of the morning bread were decreased, however, redness was increased (P<0.05). In the rheology analysis, hardness, gumminess, and chewiness were significantly decreased with increasing amounts of aronia sourdough starters (P<0.05). However, cohesiveness was the highest in the AS2 group (25% added group). In consumer preference, the highest scores were shown in AS2 group (25% added group) in color, texture, and appearance. The total polyphenol and DPPH (2,2-diphenyl-1-picrylhydrazyl) radical scavenging ability were both significantly increased along with aronia sourdough content (P<0.05). In conclusion, morning bread with 25% aronia sourdough starter showed the best quality characteristics and antioxidant activities.
