  • For the past 20 years, expert groups and citizens in Korea have debated on the usefulness of personalized medicine. These debates were mainly focussed on the possibility of the promise - people mainly discussed whether it was a probable future or if it was just a hype. Following Hedgecoe and Tutton(2002) who argue that it is only a 'rhetorial device', we will analyze about 9,000 news media coverages that deal with personalized medicine. With these data, we will show that the same terminology of personalized medicine have been used very differently according to the time and people who use it. Our research will show that this term has both diachronic heterogeneity and synchronic equivocality. This has happened because of the innate lack that exists in our symbolic system. Policy and governance regarding new technology is important because they provide quilting point to those slippery term/signifiant. Also we would like to carefully suggest that we might be able to call this phenomena as signifiant-politics.

  • The Purpose of this research is to draw implications of Multi-Functions of social welfare facilities on non-public social welfare delivery system especially in the rural area where there is not enough welfare infrastructure. The policy formation process of social welfare facilities was reviewed with 'Modified Policy Streams Framework" which combined Kingdon's Model with Mucciaroni's Model. Multi-Functions Policy of Social Welfare Facilities was led by the government with background of powerful President's initial stage of taking the power and finally legislated by amending Social Welfare Service Act in line with efficiency of non-public social welfare delivery system. However, the process did not represent the summation of needs originated from social work practice. The government just play the role of collecting some evidence underpinning the necessity of multi-functions of social welfare facilities and rearanging how to deploy the multi-functions policy. As the result the multi-functions policy is not activated and is not able to be the key criteria in expanding social welfare infrastructure. However, in spite of these limitation, the issue of multi-functions of social welfare facilities can cast the light on expanding infrastructure in the rural area where the gross size of area in larger in comparison to the district in the metropolitan city whereas residents are scattered because more number of social welfare facilities can not be the solution due to the limitation of finance and logic of efficiency.

  • As a way of identifying users' image needs for improved effectiveness of image search, there have been recent research approaches to examine contextual factors in image needs with multiple perspectives. In this line of research, this study examined a total of 70 unsuccessful image searches for the purpose of investigating users' image needs. In order to achieve the purpose of this study, in particular, the characteristics of image needs, contextual factors on image needs, and image queries were investigated. The findings of this study demonstrated that information needs from the failed image searches are categorized primarily into specific and general/nameable categories. More importantly, these information needs are embedded with multiple contextual factors, primarily, task purpose and use purpose. With an analysis of detailed use purposes for image, illustration use was found most in this data set. For query analysis, the type of unique/refined image query was revealed primarily. As the results of this study were found similar to the findings of previous studies, it is possible to characterize the image needs from the failed image searches. In addition, the findings of this study are expected to be useful to the design and service of image retrieval.

  • To become a person that is suitable to the 'High-Touch' generation where emotion takes over, we can focus on 6 skill including design, story, harmony, empathy, play, and meaning. Among these skills, harmony with design was chosen as the most important skill. Design can be seen as the basic element of all business, but it will be difficult to match the flow of the future Sensibility and intuitive generation with just the modern design that has been made based on reasonable and objective information and knowledge. This study suggests system and standardization of Sensibility surface processing design that satisfies great quality, attractive quality and Sensibility quality by applying surface processing design of product and Sensibility cognitive factors felt by the consumer by setting differentiated strategy and CMF (Color, Material, Finishing) understanding along with the importance of design materials in primary aspect. By considering the efficacy/characteristic of new surface processing characteristic/differentiation/possibility of implementation according to setting direction of differentiated CMF strategy per type of parts applied to the product, visual surface processing sample was implemented. Through this, it is expected that practical communication connected tool and Sensibility surface processing design's strategic access framework can be applied by understanding and sharing comprehensive elements such as target product, part type, applied material, applied surface processing, surface color, surface texture, and implementing feeling to environments such as designers, CMF designers, surface processing experts, and engineers in IT, electronics, and other areas. when developing a product.

  • Walnuts are one of the most economically important fruit trees in forestry. In walnut orchards, however, studies examining damage by insect pests are limited. This study was conducted to investigate the rate of damage caused by Conogethes punctiferalis to walnut fruits and by Acrocercops transecta to walnut leaves. In 2017, the change of damage rate (caused by C. punctiferalis) to fruits were investigated in Buyeo. In addition, we counted fruits and leaves damaged by two lepidopteran species in Gimcheon, Buyeo, Yeongdong, and Hwaseong. Damaged fruits steadily increased in abundance with fruit growth in Buyeo, and the highest number of damaged fruits was documented in late summer. The rates of damage caused by C. punctiferalis to fruits in Buyeo, Gimcheon, and Hwaseong were 22.1%, 20.5%, and 11.7%, respectively. Additionally, the rates of damage caused by A. transecta to leaves in seedlings (58.5% on average) were significantly higher than to those in older trees (11.2% on average), irrespective of the study location. In conclusion, this study showed that C. punctiferalis and A. transecta were serious pests affecting walnut fruits and leaves, respectively. Therefore, management methods for these insect pests need to be developed.

  • This study analyzed the repeated error patterns in division of fraction by elementary students through observation of their test papers. The questions for this study were following. First, what is the most changable thing among the repeated error patterns appeared in division of fraction by elementary students? Second, what is the most frequent error patterns in division of fraction by elementary students? First of all, the ratios of incorrect answers in division of fraction by general students were researched. This research was the only one time. The purpose was to know what kind of compositions in the problems were appeared more errors. Total 554 6th grade students(300 boys and 254 girls) from 6 elementary schools in Seoul are participated in this research. On the basis of this, the study for analysis began in earnest. 5 tests made progress for about 4 months. Total 181 6th grade students(92 boys and 89 girls) from S elementary school in Seoul were participated in this. After each test, to confirm the errors and to classify them were done. Then the repeated error patterns were arranged into 4 types: alpha, beta, gamma and delta type. Consequently, conclusions can be derived as follows. First, most students modify their errors as time goes by even though they make errors about already learned contents. Second, most students who appeared errors make them continually caused a reciprocal of natural number in the divisor when they calculate computations about '(fraction) $\div$ (natural number)'. Third, most students recognize that the divisor have to change the reciprocal when they calculate division of fraction through they modify their errors repeatedly.

  • In order to simulate the behavior of automated manufacturing systems, the performance of material handling systems should be measured dynamically. Multi-Agent technology could be well adapted for the development of simulator for distributed and intelligent manufacture systems. A multi-agent system is composed of one coordination agent and multiple application agents. Issues in AGVS simulator can be classified by the set-up and operating problems. Decisions on the number of vehicles, bi- or uni-directional guide-path, etc. are fallen into the set-up problem category, while deadlock tree algorithm and conflict resolution are in operating problem. In this paper, a multi-agent based deadlock-free simulator for automated guided vehicle system(AGVS) are proposed through the use of multi-agent technologies and the development of deadlock-free algorithm. In this AGVS simulator proposed, well-known Floyd algorithm is used to create AGVS Guide path, through which AGVS move. Also, AGVs avoid vehicle conflict and deadlock using check path algorithm. And Moving vehicle agents are operated in real-time control by coordination agent. AGV position is dynamically calculated based on the concept of rolling time horizon. Simulator receives and presents operating information of vehicle in AGVS Gaunt chart. The performance of the proposed algorithm and developed simulator based on multi-agent are validated through set of experiments.

  • Visually impaired people use tactile maps to get spatial information about their surrounding environment, find their way, and improve their independent mobility. However, classical tactile maps that make use of braille to describe the location within the map have several limitations, such as the lack of information due to constraints on space and limited feedback possibilities. This study describes the development of a new multi-modal interactive tactile map interface that addresses the challenges of tactile maps to improve the usability and independence of visually impaired people when using tactile maps. This interface adds touch gesture recognition to the surface of tactile maps and enables the users to verbally interact with a voice agent to receive feedback and information about navigation routes and points of interest. A low-cost prototype was developed to conduct usability tests that evaluated the interface through a survey and interview given to blind participants after using the prototype. The test results show that this interactive tactile map prototype provides improved usability for people over traditional tactile maps that use braille only. Participants reported that it was easier to find the starting point and points of interest they wished to navigate to with the prototype. Also, it improved self-reported independence and confidence compared with traditional tactile maps. Future work includes further development of the mobility solution based on the feedback received and an extensive quantitative study.
