  • There is a lack of user centered design methods that support effective collaboration between designers and end-users for designing hardware and software integrated digital products. This paper presents the application of Collaborative Design and a new collaborative design prototyping tool for interactive digital product design projects. The tool consists of STCtools(State Transition Chart tools) software, hardware modeling materials, and physical interface toolkits for integrating software and hardware. STCtools allow users to create and edit States, to compose Events describing transitions between States, and to run intermediate or final results of STC. Using the hardware modeling materials and the physical interface toolkit, designers and end-users can collaborately examine the hardware and software integrated concepts in an early stage of the design process. Three collaborative design workshops of designing a portable digital guide for a theme park were accomplished to examine the feasibility of the tool. The results suggested that the tool supported iterative concept development and interactions between designers and end users. Although several user interface problems of STCtools were identified, the participants gave positive feedback on the role of the tool in collaborative concept generation and deployment. It is expected that the results of this study contribute not only to the collaboration between designers and end users, but also to the collaboration between designers, and between designers and other professionals.

  • The growth inhibitory effect of wheat grain, fermented wheat grain products, red pepper powder and kochujang was examined in AGS human gastric adenocarcinoma cells. The kochujang samples were prepared by mixing red pepper powder and each fermented wheat grain products, such as first fermented wheat grain (FFWG), second fermented wheat grain (SFWG) and final fermented wheat grain (FiFWG). The methanol extract of FiFWG showed the highest growth inhibitory effects. In order to investigate the effects of fermented wheat grain products at each stage of fermentation on anticancer activity, the kochujang prepared with red pepper powder and each of FFWG, SFWG and FiFWG were fermented until reaching pH 5.1. The kochujang adjusted to pH 5.1 by fermentation increased the growth inhibitory effect; however, the kochujang prepared with FiFWG showed the highest effect. Increased fermentation time increased the growth inhibitory effect of kochujang when prepared with FiFWG. These results suggested that the anticancer effect of the kochujang on the gastric cancer cells was affected by the fermentation periods of the wheat grains. The well-fermented end products of the wheat grains seem to be one of the major components that showed anticancer activity of kochujang.

  • The term 're-use' here signifies the re-use of end-of-life products without changing their form after they have been thoroughly inspected and cleaned. In the re-use network model, the distributor determines the product order quantity on the network through which new products are received from the suppliers or products are supplied to the customers through re-use of the recovered products. In this paper, we propose a reusable network model for reusable products that considers the total logistics cost from the forward logistics to the reverse logistics. We also propose a reusable network model that considers the processing and disposal costs for reuse in an optimal inventory management environment. The authors employe Genetic Algorithm (GA), which is one of the optimization techniques, to verify the validity of the proposed model. And in order to investigate the effect of the parameters on the solution, the priority-based GA (priGA) under three different parameters and the modified Hybrid GA (mhGA), in which parameters are adjusted for each generation, were applied to four examples with varying sizes in the simulation.

  • To compare and analyze technical system related to manufacturing of ironware during the period of the Three Kingdoms, an analysis was conducted on the minute system of metalwork, as study objects, of the remains of the Mt. Wolpyeong fortress wall in Daejeon in the period of capital during the era of the Three Kingdoms in the 5th century, the Sanwol-ri remains in the 6th century in Gunsan and the remains of ironware excavated from the great ancient tomb of Hwangnam of the Silla dynasty in the 5th century. The result of analysis shows that in the most of the casting products, the minute system of white cast iron were contained. While the iron part of decarbonization was in the system by casting as white cast iron in the central part, on the surface layer it was turned out that comparatively uniform 100% pearlite system of about 1~2mm degree was existing. The part of pearlite on the surface layer was caused by decarbonization, which appears in all the parts of blade front end and handle. Therefore, it was found that the iron part of decarbonization was manufactured by casting, and then was processed at the high temperature by decarbonization. For the products of forging, after processing the products on the basis of pure iron for materials, they manufactured the ironware that raises the strength by carbonizing that keeps carbon infiltrated on the necessary part, by the method of black smith welding that add pure iron to steel, or by varying the method of heat processing onto the part required of strength. Though limited, we could understand that the technical systems for manufacturing skill of ironware in the areas of Baekje and Silla were different each other. In the technical system for Hwangnam great ancient tomb in the Silla area, it is found that they had raised the strength on the necessary part by applying the steelmaking method of carbonizing in the last stage of production of products, in the meantime in Baekje area, it appears that they had produced steel in advance in the first stage of production of the products, and used the produced steel only to the necessary part.

  • This study discussed implications of the increase of single person households (SH) for high-tech industries especially focusing on artificial intelligence (AI) adopted products, based on critically reviewing the past researches on their characteristics including consumption trends; the improvement of AI technology; and its market potentiality in various industries. According to the results, SH spent more time with others like friends and neighbors more than couples. Younger people increasingly chose to live alone by their own free will for achieving their goals. 'Living alone' or 'going solo' is not thought negatively any more, but as a new market power in the future. Considering their value oriented consumption behaviors based on spirit of independence and individualism, they will need high-tech products more like AI adopted products than others because of their advantages for the value of single life. Thus, the rapid progress of AI technology is predicted to bring them satisfaction of their wants and it is suggested to prepare for the market segmentation of SH as AI end-users.

  • The goal of this study is to promote the spread of environmentally friendly agricultural products, which have been receiving a lot of attention lately, as a way to improve food safety and quality. As a result of the increased labor input, increased production costs, and an aging population, environmentally friendly agriculture is making it more difficult for farmers to expand their enterprises. In the meantime, consumers find it difficult to spread eco-friendly agricultural products due to their high expectations for safety and quality, as well as the desire to purchase products at a reasonable price. Previous studies have revealed differences in perceptions between eco-friendly agricultural producers and consumers. In light of this, this study divided consumers based on their characteristics (such as age, purchase history, health concerns, etc.), and different policies were proposed in order to increase purchasing factors for each group based on their characteristics. In order to gather information for this study, general citizens were asked about their perceptions of eco-friendly agricultural products, future purchase intentions and awareness, reliability, necessity, purpose, and information sources. A two-step clustering analysis was conducted using nominal and continuous variables simultaneously. The paper presents the three derived group differences (senior organic interest group, middle-aged organic interest group, and indifferent young organics) as well as group differences for the purchasing/non-purchasing factor analysis and policy improvement for each group. An eco-friendly agricultural product distribution proposal was made at the end of this article.

  • A number of studies have been conducted on the evaluation of bi-national products, but studies that may be applied in practice are lacking. This study suggests several implications for bi-national products in the sub-market using a more specific approach than previous studies. To this end, this comprehensive comparative study reflects the purchasing routes, product category, and consumers' personal characteristics (regulatory focus, prior knowledge) of bi-national products. Results found the evaluation of bi-national products according to purchase routes showed that consumers in offline stores were more favorable than consumers in online stores. In comparison with product categories, necessities were more positive than luxury goods. On the other hand, according to consumer's personal characteristics, consumers with promotion focus tendency perceived brand preference more highly than consumers with preference focus tendency. Also, it was found that groups with high prior knowledge had a positive evaluation of products compared to low knowledge groups.

  • "Charmdlerak" a new high-quality Korean wheat, was produced with production management from the Rural Development Administration (RDA). We evaluated the characteristics of grain, flour, and end-use quality of "Charmdlerak" wheat to assess consumer satisfaction with this new variety of wheat. Eighty-two farmers (450MT/100 ha) in Gwangju metropolitan city produced Keumkangmil wheat and 23 farmers (30 ha) produced "Charmdlerak" wheat "Charmdlerak" wheat had 1.55% ash content and 11.0-13.0% protein content "Charmdlerak" flour was milled by a commercial machine in Samyang Milmax. The protein content of "Charmdlerak" was slightly higher than that of flour from Hard Red Winter Wheat (HRWW), the most popular multipurpose flour in Korea. The ash content and color of "Charmdlerak" wheat were similar to those of HRWW. End-use quality testing of cooked noodles and bread indicated that "Charmdlerak" flour resulted in softer noodles and similar bread loaf volume compared with products made from Keumkangmil wheat.
