Objectives : The elderly in South Korea are the poorest among OECD countries in 2015. The aim of this study was to explore the health and life of the low-income elderly living in vulnerable areas in a metropolitan city. Methods : Data were collected through in-depth individual interviews with 7 participants from October to November 2015 and analyzed through Colaizzi's phenomenological methodology. The participants were interviewed for over 60 minutes in each person. Results : 7 categories were identified from 17 subcategories: "My life history: sick body," "Living with a sick body," "My poor but precious life," "A sense of distance from the hospital," "Narrowed area of my life," "Thankful for help," and "The village where I have lived my destiny." There is a lack of medical accessibility, mobility, and economic independence for low-income seniors. In addition, full-fledged redevelopment comes to them as violence. Conclusions : The health and life of the low-income elderly in vulnerable areas are products of many social factors, reaffirming the importance of social health.

The purpose of this study was to analyze the characteristic of each view in an apartment unit in terms of the quality. This study was accomplished by two research methods; the field survey on 181 apartment complexes in Daegu, and the preference evaluation on 24 cases sampled in the sense of its location, i.e. inside or outside of a complex. In the field survey, view targets were categorized into various items such as a building, a road, a mountain, a tree, another apartment, the sky, and so on, and the characteristics of the distance from a viewer to view targets and view of the level in an apartment were analyzed. In the preference evaluation, 24 cases, each one has one of the follows; the natural view, the artificial view, and the combined view of the both, were chosen and those were evaluated by 167 interviewees. As a result, the conclusions from the study were drawn as follows; 1) The view, the combination of buildings, roads, mountains, trees, apartments, and the sky, is usually seen in an apartment unit. 2) The type of view target is more significant to a person than its location. 3) The natural and combined view are preferred to the artificial one. 4) In the case of the same outside view, a person likes the open view more than the somewhat covered one.

In this research, I conducted a semantic network analysis centering on media articles on purchasing, revitalizing, and utilizing the former Busan branch of Hansung Bank, a modern architectural heritage. We sought the most efficient analysis elements for the analysis of the social arguments about preservation and utilization embedded in media articles. For this reason, Degree Centrality measures how many connections the word described in the media article has, and Betweenness Centrality measures the influence that controls the flow of information through correlation I examined. In addition, keyword that express the theme well examined the aggregation structure in each sub-network. In this research, in theoretical terms, it makes sense in that the social discussion embedded in the article of the mass media is grasped empirically through semantic network analysis of words. Methodological aspect is best when it includes nouns and adjectives and the distance between words is more than four words in the analysis of the cohesive structure of the semantic network to determine whether the influence of social discussions is best assessed through the connection between words to media articles.

The turning point is one of the more evocative concepts in the critic's arsenal, as it is equally suited to the evaluation and analysis of a given moment in one's day as to those of a historical event. But how does one recognize a turning point? As we find ourselves always "in the middest," both spatially and temporally, we inhabit sites that may be points at which many things may be seen to turn. Indeed, it is usually only possible to identify a turning point, as it were, from a distance, from the remove of space and time which allows for a sense of recognition, based in part on original context and in part of perceived effects. In this article, Robert T. Tally Jr. argues that the apprehension and interpretation of a turning point involves a fundamentally critical activity. Examining three models by which to understand the concept of the turning point-the swerve, the trope, and peripety (or the dialectical reversal)-Tally demonstrates how each represents a different way of seeing the turning point and its effects. Thus, the swerve is associated with a point of departure for a critical project; the trope is connected to continuous and sustained critical activity in the moment, and peripety enables a retrospective vision that, in turn, inform future research. Tally argues for the significance of the turning point in literary and cultural theory, and concludes that the identification, analysis, and interpretation of turning points is crucial to the project of criticism today.

The study of a new expression within Korean ink painting that meets the demands of the times has continued, resulting in various expressions with acrylics, handycoat, objects and installations, crossing over from traditional Korean painting techniques. A 'margin' was both a very important space and esthetical matter that expresses 'Ki', 'Distance', and 'Omission' in traditional sense when addressing Korean ink painting Its expression methods and concepts, however, have changed today. A 'margin' through Montage technique can be a significant example in understanding the expression methods of today's Korean ink painting. This is because the margins in Montage make the meaning of the work various and flourished and deeply construct the surface with a double-layered structure, instead of using a single layer. These 'margins' created by Montage are spaces where different images conflict, divide and continue with each other and where a reconciliation between different spaces is accomplished. Furthermore, they establish more vitality and truthfulness to life through both the images conflict and reconciliation. After the adoption of Post-modernism Art in Korean ink painting, the characteristics of the 'margin' in Montage style by the division of surface are an 'acceptant's participatory imaginative space'; where viewers fill the margins with their imaginations ; an 'abandoned space' ; where unnecessary parts are deleted for more live surface ; and a 'strategic space', where the work enriches the structure and contents of surface by using margins strategically.

Ultrasonic sensors are widely employed in detecting range to a target by the virtue of their low cost and simplicity. However, the sensor's measurements are corrupted by systematic errors due mainly to the dependency of sound speed upon surrounding conditions and random errors of uncertain origin. In this paper, we present the results of research carried out to reduce these errors for increasing the reliability of an untrasonic sensor system to be used in orbotic or other automated system's range finding. The sensor system designed herein is in a peuliar structure having a reference target and two receivers. Echoes from a small reference target placed at a known distance are used for compensating the variations of sound speed according to the changes of sensing conditions. Unlike existing ones, the technique proposed can compensate the effects of temperature or any other physical parameters without an additional sensor dedicated to the compensation. The measurements by two redundantly employed receivers are fused to reduce random errors in a statistical sense. The correlation of the signals from the receivers sharing a hardware in part is considered in the fusion process. The methodology desicribed in this paepr is conceptually simple, easy to be implemented, and effetive to increase the accuracy of the sensor measurements as experimental results confirm.

Development of technology in the $20^{th}$ century has made great contributions to women's lives. With the development of digital convergence, home network, and DMBs (Distance Method Bracings), the ubiquitous technology information era is expected to create a new progressive era for women. The purpose of this study is to investigate the lifestyle that Korean women would like to pursue, especially in regards to the sense of value within the personal and social life of each individual. As a method to suggest how the socio-cultural trends of women's lifestyle will change in the ubiquitous era, qualitative interviews have been conducted over 6 groups with 77 persons between the digital ages of 20s and 30s, living in Seoul. The majority had positive opinions regarding the economic, cultural, emotional, and physical prospects of the ubiquitous information environment. Results show high expectations evolved around freedom from household chores, the equality between the sexes (at home and in society), enhancing the working environment at home, an expansion of human relationships leading to creative knowledge, being able to maintain a single life without economic constraints, and the enjoyment that the internet provides. for suggestions to improve the quality of women's lifestyle through ubiquitous technology, issues such as individual based customization, time management, creating emotional hyperspaces, multi-media communication systems, and women as leaders were studied.

The purpose of this study is to investigate hand and sensibility of PET treated by Ultra-Violet (UV). The 4-channel PET knit fabric was treated by a self-made UV instrument in 5cm distance with different time frames-0min, 30min, and 90min. For hand evaluation, mechanical properties were measured by the KES-FB system. The environmental condition was controlled at 29$^{\circ}C$, 75% (R.H.)-summer standard climate. Twenty female students evaluated 'roughness', 'smoothness', 'wetness', 'stiffness', 'coolness', 'touch', 'preference', and 'comfort'. The outcomes of the experiment are as follows: The surface roughness of mechanical properties showed significant differences and the value of PET irradiated by UV for 90min was highest. The order of primary hand value such as NUMERI and FUKURAMI was in a following order-Untreated > 30min treated > 90min treated. Total hand value showed that PET irradiated by UV for 90min was appropriate for using summer fabric. The results of subjective sensibility were that the untreated and 30min treated PET were recognized as similar and had a good evaluation on 'comfort', 'preference' and 'the sense of touch'. This consequence disagreed with total hand value, because it was considered that subjects' hand sensibility was dependent on the feel of smoothness.

A virtual force is generated and fed back to the operator to make the teleoperation more reliable, which reflects the relationship between a slave robot and an uncertain remote environment as a form of an impedance. In general, for the teleoperation, the teleoperated mobile robot takes pictures of the remote environment and sends the visual information back to the operator over the Internet. Because of the limitations of communication bandwidth and narrow view-angles of camera, it is not possible to watch certain regions, for examples, the shadow and curved areas. To overcome this problem, a virtual force is generated according to both the distance between the obstacle and the robot and the approaching velocity of the obstacle w.r.t the collision vector based on the ultrasonic sensor data. This virtual force is transferred back to the master (two degrees of freedom joystick) over the Internet to enable a human operator to estimate the position of obstacle at the remote site. By holding this master, in spite of limited visual information, the operator can feel the spatial sense against the remote environment. It is demonstrated by experiments that this collision vector based haptic reflection improves the performance of teleoperated mobile robot significantly.
