This study aims to obtain the basic data in order to develop the distributive justice reasoning program for preschooler. To fulfill this aim, this study investigated the parents' and kindergarten teachers' preference in the selection of the traditional fairy tale and the extent to which parents' and kindergarten teachers' evaluation of the traditional fairy tales dealing distributive justice are in agreement with each other. The subjects were 240 parents and 78 kindergarten teachers selected from five cities in Korea. The questionnaire with six Korean traditional fairy tales which deal with the sharing problem among the friends and the families was used. The data were analyzed in SPSS Win 10.0 program, by frequency, percentile, mean, standard deviation, ${\chi}^2$ and t-test. As a result, most important factor in selecting the traditional fairy tale was the title and the editing state of the book for the kindergarten teacher, while it was the good fame of the press for the parent. The congruence existed between parents' and kindergarten teachers' evaluation in knowledge, adaptability for modern times, amusement and empathy in the function of the traditional fairy tales regarding distributive justice. Meanwhile parents evaluated the traditional fairy tales are more adaptive for value formation and useful than teachers did.
This study selected commonly known species of fruit trees, and re-selected the species that endure the stress of extreme cold weather and physiologically restore themselves to the previous state until the following year. Then we could go ahead to propose the species that were appropriate as urban greening plants in weather condition of any part of the country. To do this, we conducted an experiments for six species of fruit trees based on the preference of the general public and recommendation of the experts; Morus alba (English name: mulberries), Diospyros kaki (English name: Persimmon), Prunus persia (English name: Peach), Elaeagnus umbellata var. coreana (English name: Korean Autumn Olive), Malus domestica 'Alps Otome' (English name: Alps Otome), and Prunus mume (English name: Blue Plum). The experiment verifies whether the trees survive without any stress from the cold weather under the national climate conditions (one in the suburbs of Seoul: Yongin city, one in the central Chungcheong region: Daejeon city, and in the southern Gyeongsang region: Jinju city in Korea). The experiment lasted for a year from August 2016 to August 2017. The levels of electrolytic efflux, chlorophyll content, plant height, fresh weight, and dry weight were measured four times (on August of 2016, January, February, and August of 2017) for each tree planted bare ground outdoors. Results showed that Diospyros kaki, Prunus persia, and Malus domestica 'Alps Otome' were proven durable and resistant to winters of all three areas (one in the suburbs of Seoul: Yongin city, one in the central Chungcheong region: Daejeon city, and in the southern Gyeongsang region: Jinju city in Korea). Especially, the increase of chlorophyll content and the reduction of electrolytic efflux were noticeable in Prunus persia than in the other two species, proving itself as the most cold-tolerant among the six species used in the experiment. In addition, interpreting from the physiological restoration data of one-year span before and after getting through winterer, Prunus persia was proven to be the most cold-tolerant species.
The purpose of this study was to analyze the state of Goryoin housing in Uzbekistan and Korea. Using ethnographic methodologies, it was examined that 20 Goryoin households in Korea in relation to their usage of housing space firstly and also tried 20 Goryoin households in Uzbekistan with the same method. The following conclusion were established; 1). The majority of households in both areas preferred separated kitchen and living room areas. 2). Most households in both areas had a washing machine in bathroom and they regarded bathtub and the drain hole of the bathroom as very necessary. They all preferred separate bathroom and toilet areas in order to allow simultaneous use. 3). Their preferred seating style was chairs on sleeping and eating especially but they treated large family and guest without chairs in both areas. 4). All of them were took their shoes off and wore slippers at home usually and also had a preference for designated shoes space at the entrance to the house. 5) All of households in Uzbekistan and half of them in Korea had a carpet or mat in the bedroom or living room, both for keeping warm and aesthetic reasons. 6). The heating system of apartment in Uzbekistan was radiator and most of private houses had a modified Ondol with radiator but their preferred heating system was modified Ondol in both areas. 7). They all considered the living room as the most important housing space for family and guest in both areas.

In this paper, we design Input/Output modules as a preference work for implementation of hybrid two stage AWG based WDM-PON and verify operations of each function modules through the logic simulation. This WDM-PON system provides service to 128 ONUs through 32 wavelength and one wavelength is shared for upstream transmission with four ONU while each wavelength is allocated to each ONU for downstream transmission. The designed WDM-PON MAC chip is based on sub-MAC which consists of one control unit and reception unit and four transmission unit. To design the reception and transmission unit of sub-MAC, we define the functions of the sub-MAC, pins of the modules, control signal and timing of each signal. We intend to design MAC chip with 1Gbps transmission rate. Thus the designed MAC chip is worked on 125MHz clock rate. We define FSM and design Input/Output modules with VHDL. The logic simulation of the modules is executed by the ModelSIM simulator.
This study aims to analyze the design of current nurse uniforms, investigate the state of nurse uniforms, and uniform design preferences in order to ultimately develop functional nurse uniform, which satisfy their needs. First, observing photos of nurses' campaign on wearing a badge showed that opening of top uniform almost always incorporated buttons, and sleeves were mostly set-in half sleeves while collars tended to be mandarin collars. The colors were mostly white for both top and bottom, while the top showed a bit more variety in colors. White tops often incorporated hospital logos on them. Second, in terms of the nurse uniform distribution, each nurse is given one top and one bottom per year. In addition, either a cardigan or a jacket on top of the regular summer uniform constitutes the winter uniform, whereas the availability of cardigans differed by hospitals. Third, the main source of contamination of uniforms was blood, and the level of satisfaction was all low in terms of the design, function, and material of the uniform, calling for the enhancement and development of new uniforms. Design preferences were two-piece with pants, color preferences were blue and pink, and pattern preferences were hospital logo, stripes, and check patterns in the listed order of preference. Complaints were usually made on the contamination of front pocket of the top, lack of sufficient pockets for storage, and tightness of the sleeves. Some preferences on finishing were the princess seams, mandarin collar, set-in half sleeves, and button closing on top. The preferred belt was a mixed form of straight-lined belt and rubber belt, and straight lined hem and spandex blended fabrics were favored for the clothing.
It is important to compare the present condition of railway and marine freight transportation corridors to make good progress for freight transportation to the Eurasia region.

The vehicle navigation system is developed for helping driver to retrieve driving information more easily and fastly. Navigation System informs driver many pieces of driving information - roadway structure and system, on-line traffic condition, the position of vehicle, route guidance, destination and other information service. As the style of information is diverse and the amount of information is large, driver may have mental and visual overload. The display of information can disturb the driver's attention and this can cause accidents. This state is caused by the defect of human-machine interactions. When the navigation system is designed, human factors - cognitive, judgment, operating - must be considered. The display style must be designed simply and easily, not to be obstacle of human -machine interface. In this study, outside-in view display style and inside-out view display style are compared each other. Two factors are measured. One is cognitive factor-time of cognition on information that is displayed by screen display, cognition error rate. The other is image of screen display - subject's feeling about several styles of display, degree of subject's preference. The prototype of roadway is four kinds - Cross, T-cross, Y-cross and O-cross. Roadway display for test is taken from paper maps. Traffic condition display style, vehicle position display style and route guidance display style are taken from current display style. Traffic condition display style is symbol. Vehicle position display style and route guidance display style are described as color and symbol. The test on screen display is implemented doing given tasks. Then the test is analyzed statistically, The result of test analysis gives the guideline to the designer for the map display of the vehicle navigation system.
With the increase of elderly people, educators have begun designing experiences to prepare students to work with elderly group. The purpose of this study is to evaluate the knowledge and attitude of students majoring in food and nutrition for the elderly and their intentions to provide services for the elderly. The knowledge level of the students was in a medium range, and no relationship was found between knowledge and attitudes using Pearson correlation. The knowledge did not significantly differ across gender and academic level when compared using t-test and ANOVA, but knowledge level was significantly different based on residential experiences with elderly over 65 years of age (p < 0.05). Students had neutral attitudes toward working with elderly employees and working for elderly. Students had positive intentions to work with elderly employees, seek employment in an organization for elderly clients/customers, and seek opportunities for positive social interaction with the elderly. However, students do not have positive work preference with elderly employees. As a result of multiple regression analysis, it was found that knowledge was not a predictor of intentions to provide services to the elderly. However, attitudes toward working with elderly employees, attitudes toward elderly, residential experiences with elderly > 65 years have been predicted the intentions to work with elderly employees. Attitudes working with elderly employees and attitudes toward elderly influenced the intentions to work in the organizations to provide services to elderly. This study can be identified the need for additional didactic preparation and experiences to prepare students to work with elder aging population.
Purpose: We consider export of Korea for Muslim population of Cairo residents in Egypt. Product instant cup noodle and yuzu tea are mainly focused on Kano model and Timko's customer satisfaction factor (CS - Coefficient) analysis and conjoint analysis. Methods: Based on the evaluation and conjoint analysis, cluster analysis was additionally applied to further exploratory research as to what kind of population the target customer has. A total of 120 people, each 60 people each, were prosecuted for Muslim women, middle middle class who had over 3,000 Korean won annual income for that study, and in Cairo in August 18. Results: The Kano analysis result Instant cup noodles act as attractive elements for packaging state, cooking method, smell and convenience, and Yuzu tea acted as an attractive element of taste, eating method, raw materials, efficacy, packaging form. Customer satisfaction factor, instant cup noodles, capacity and noodle thickness was a factor of indifference in Kano analysis, but acted as an attractive factor, the way to eat citron tea was classified as a factor of indifference. Conclusion: In the case of instant cup noodles, we first set up the taste of chicken-based soup with high appreciation as a whole, a group that likes chicken-based soup taste and oil noodles for each market segment, a taste of beef based soup And popular group that likes raw noodles Appears that diversification is necessary, and it has been found that it is necessary to develop a product type by hierarchy and marketing with different size priority from group packaging container. In the case of Yuzu tea, it is indispensable to emphasize the efficacy, in particular, energy recovery preference appears high, appealing point matching the needs of energy recovery is necessary, release the citrus fruit as a product without buckwheat in Bisson Ho, the packaging container, The group that likes cups and sticks is different and we found that it is necessary to prepare all two types.

Purpose: The purpose of this study was to evaluate the image quality, diagnostic efficacy, and radiation dose associated with the use of a cadmium telluride (CdTe) detector, compared to charge-coupled device (CCD) and complementary metal oxide semiconductor(CMOS) detectors. Materials and Methods: Lateral cephalographs of a phantom (type 1) composed of synthetic polymer filled with water and another phantom (type 2) composed of human skull macerated with polymer coating were obtained with CdTe, CCD, and CMOS detectors. Dosimeters placed on the type 2 phantom were used to measure radiation. Noise levels from each image were also measured. McNamara cephalometric analysis was conducted, the dentoskeletal configurations were assessed, and a subjective evaluation of image quality was conducted. Parametric data were compared via 1-way analysis of variance with the Tukey post-hoc test, with a significance level of 5%. Subjective image quality and dentoskeletal configuration were described qualitatively. Results: A statistically significant difference was found among the images obtained with the 3 detectors(P<0.05), with the lowest noise level observed among the images obtained with the CdTe detector and a higher subjective preference demonstrated for those images. For the cephalometric analyses, no significant difference (P>0.05) was observed, and perfect agreement was seen with regard to the classifications obtained from the images acquired using the 3 detectors. The radiation dose associated with the CMOS detector was higher than the doses associated with the CCD (P<0.05) and CdTe detectors(P<0.05). Conclusion: Considering the evaluated parameters, the CdTe detector is recommended for use in clinical practice.
