This paper is focusing on the optimal size of internal space in which various functions are expressed by means of analogizing appropriate size of passage fitted to characters and reverse-calculating it in comparison with preexisting games, and thus increase the objectivity of data. To this end, the work of making the data objective was conducted in advance, and the experiment proceeded in the way that specially-designed Dungeon can make its way through the passage and in the situation where small-scale combats take place. In addition, the efforts were made to standardize the outcome of experiments by restricting the types of game graphics to MMO RPG. Further, the enhance the objectivity of size of the characters, the game types were limited to RPG games, and it is also adjusted to the character's face size based on the graphic designer's preference. The size of shoulders and arms of characters, inter alia, was selected as distinguishing points to be adjusted to the passage. By analyzing these data, the size of passage was re-organized according to the main characters in the MMO RPG games. Four experimental data was utilized by the 200 game experts in order to select the optimal size of passage in the game. As a consequence, the proportional correlation between character and passage movement was evaluated as successful in terms of emotional recognition.

This study aims to investigate the effects of pre-service elementary teachers' scientific self-efficacy by science motivation according to the academic track in high school. The subjects of this study were 525 pre-service elementary teachers of which 350 pre-service elementary teachers were selected from the humanities and social sciences track in high school and 175 pre-service elementary teachers were selected from the science-engineering track in high school. In order to investigate the difference between scientific self-efficacy and science motivation among pre-service elementary teachers, Independent sample t-test and Cohen's d were done. In order to find out about the Influencing of scientific self-efficacy on science motivation, multiple regression analysis was used. The results of this study were as follows: First, there were statistically significant differences in scientific self-efficacy and science motivation, and the average of pre-service elementary teachers who selected science-engineering were significantly higher. Second, explanation power of scientific self-efficacy on science motivation appeared as 66.7~68.3%. The explanatory power of pre-service elementary teachers' who selected humanities and social sciences were higher. The relative importance was high in task difficulty preference factor to humanities and social sciences, was high in self-regulation efficacy to science-engineering.

Liquefied petroleum gas (LPG) is an attractive fuel for ships considering its current technology and economic viability. However, safety guidelines for LPG-fueled ships are still under development, and there have been no cases of applying LPG propulsion systems to small and medium-sized ships in Korea. The purpose of this study was to perform an objective risk assessment for the first marine LPG engine system and propose safe operational standards. First, hazard and operability (HAZOP) analysis was used to divide the engine system into five nodes, and 58 hazards were identified. To compensate for the subjectivity of qualitative evaluation using HAZOP analysis, fuzzy set theory was used, and additional risk factors, such as detectability and sensitivity, were included to compare the relative weights of the risk factors using a fuzzy analytical hierarchy process. As a result, among the five risk factors, those with a major impact on risk were determined to be the frequency and severity. Finally, the fuzzy technique for order of preference by similarity to ideal solution (TOPSIS) was applied to select the risk rank more precisely by considering the weights of the risk factors. The risk level was divided into 47 groups, and the major hazard during the operation of the engine system was found through the analysis to be gas leakage during maintenance of the LPG supply line. The technique proposed can be applied to various facilities, such as LPG supply systems, and can be utilized as a standard procedure for risk assessment in developing safety standards for LPG-powered ships.

This study was conducted to grasp distribution of native plants in flower market and uses of native plants in floral decoration. This study was investigated native plants sold in flower market(2017.01-2017.12) and their monthly sales. Also, this study analyzed the use of native plants, frequency of native plants classified by form and color of native plants used for floral decoration in flower magazines 'Fleur' and 'The Flower'. Among 172 species distributed cut-flower, native plants in Korea flower market are only 24 species(14.0%). Number of filler flower(15 species) is more than other forms. Native plants used in 'Fleur' and 'The Flower' were 14 species(10.2%) and 17 species(9.6%), it is meaning that native plants were less used than foreign plants. The number of filler flower was the highest in both magazines, but form flower(299 works) in 'Fleur' and mass flower(571 works) in 'The Flower' are used most frequently. According to color analysis of native plants used for floral decoration, P(purple), PB(navy) and RP(reddish purple) were 57% of the total. It can be increased native plants uses in flower decoration with developing form and mass flower considering color preference.

The characters that could be connected to diverse cultural contents have formed diverse platforms with the development of digital technology, and the size of the relevant industry and market is rapidly growing. Recently, the utilization of character emoticons for smartphone messenger has been rapidly increased, so that the characters are settled down as a tool for non-verbal communication, on top of drawing attention as an independent area. With the expansion of character market, the importance of design that could give interest and familiarity to consumers is more emphasized. The body proportion of characters includes the implicative and symbolic meanings that could express diverse personalities. Thus, this study examined the body proportion of the characters with the high consumers' preference, and then analyzed the characteristics of formative elements of character design in accordance with the body proportion. In the results of the analysis, the exaggerated form of SD characters in two or three-head figure, and the realistic Real characters in seven or eight-head figure were preferred. For the SD characters, the colors with a high chroma showing the cute and cheerful image were used. For the Real characters, the cubic effect was expressed through the colors with active images and the light and shade of color. Even though the SD characters have limited motions due to the omitted body parts, the facial movements of animation characters are exaggerated while the Real characters describe the realistic and dynamic motions.

Along with a rapid increase in the number of 1-person households where the concept of 1-person consumption and 1-person economy is emphasized, the proportion of 1-person household in Korea occupies a 25.3% at present, and the number is expected to grow continuously. And this rapid increase will bring about a host of problems such as housing shortage in the metropolitan area, egoism, loneliness felt by individuals, and other social problems such as crime. As an alternate movement to this phenomenon, concern on and interest in community, community culture, and sharing of space are on the rise, together with concern on and preference for sharehouse culture. In news media as well, articles on life shared with members of a sharehouse often appear. This sharehouse, which is widely spread and well received in Japan, not only reduces economic burden but also creates their own community and promotes their own culture. In this sense, it is a new way of life that represents benefits of sharing, well beyond just economic interests. Accordingly, In this research, an attempt was made tp examine the circumstances in the use of space based on existing studies on sharehouse characteristics in order to shed new lights on the meaning that non-characteristic space concept of the traditional residential space has as the concept of sharehouse space by considering it in connection with the non-characteristic space concept of the Korean traditional residential space where diverse circumstances occur centered on communal life and which were accepted by all naturally.

There are exhibit commentary media (docent, mobile device) for assisting family visitors in the museum, and the communication within family members could be affected by which media they use. When using a docent, family visitors lowered their voice or restrained talks for paying attention to a docent' explanation. When using a mobile device, family visitors mainly relied on a mobile device, so they did not pay attention to the objects. The results of the survey showed that parents reported no difference between the docent and the mobile device on some measurement items and preferred the docent to the mobile device on other measurement items. On the other hand, children showed strong preference toward the mobile deice over the docent because of their enjoyment for operating the mobile device. Regardless of which media they used, the communication among family members could be enhanced by being together. Therefore, the museum should design and operate a docent program for family visitors to enhance the communication among family members. In addition, the museum should consider how family visitors using a mobile device would pay attention to objects and enhance the communication.
