  • As a part of the ITS, the traffic information system is more widely adopted to deliver traffic information to vehicle drivers via various types of media. As the ITS system establishment has been recognized as somewhat accomplished, the focus has shifted to the efficient operation and maintenance of the system. In this paper, we propose a method for evaluating a VMS traffic information service system from a user's perspective. In particular, relational expressions for the level of information provided and the level of user satisfaction are generated for the evaluation to take place from the user psychological satisfaction aspect of all other beneficial features of the system. As continuous flow facility is the one that has limited entry and exit, the traffic information of VMS plays a significant role for vehicle drivers to make their decisions. A method suggested in this paper could be used for evaluating an existing system as well as setting up the target service level of the system of a new system. If individual system properties are considered along with various VMS functions being as supplement of this research, more systematic evaluation method could be arranged.

  • Horticultural therapy is a complementary therapy by trained professionals utilizing plant and horticultural activities as media to pursue the positive change of clients, which resulting from stimuli of plant nature, activities, and interaction with other people. Outdoor horticultural activities provide clients with the opportunities of the contact to nature such as fresh air and sunlight as well as plants. But the importance of plant nature to client's health has not been fully acknowledged compared to that of therapist's role and activities in horticultural therapy in Korea. In horticultural therapy it is possible for client to participate on the various levels from passive viewing to active gardening according to the client's ability. Therefore it is necessary for horticultural therapists to consider the therapeutic factors of plant nature to maximize the therapeutic effect of horticultural therapy. The purpose of the research is to clarify the therapeutic factors in the contact of client with plant nature and to emphasize those importance in horticultural therapy. From the review of the experimental researches five therapeutic factors were revealed: Natural light, plant natural view, natural sound, aroma(volatile oils of plants), and plant itself. This paper raises the importance of outdoor activities in horticultural therapy and the necessity for severely handicapped clients to the contact with plant nature, though passively.

  • This study considers aesthetic characteristics by examining fashion style of fashion journalist Anna Wintour. Fashion journalists are specialists who work at fashion media. Especially, Anna Wintour is one of the most famous fashion journalist in the world and fashion icon, who has been editor-in chief of Vogue USA since 1988. For this study, Anna Witour's photograph was collected from 2010 to 2015 on web-sites. After collecting images, it analysed with 4criterions which were silhouette, color, fabric(pattern and texture) and hair style(and accessories) following advance researches analysis about fashion style. The conclusions of this study are as follows. First, symbolism revealed that could express her identity through utilizing steady items such as blond bob hair, Chanel bold sunglasses, short round neckless and Manolo Blahnik's low-heeled slingback nude sandals. Especially, she gave consistency to her fashion style with fixed hair style and accessories which are similar in shape. Second, femininity, that reveal as an internal characteristic such as sensitivity and as an external characteristic like fluidity. Anna Wintour expressed femininity with elegant curvy silhouette, various of color and flower pattern. Particularly, she emphasized nature women's body shape with princess silhouette, slim silhouette. Third, analysis result indicated characteristic of authority with oversize silhouette, wide lapel details and glamorous genuine fur items. Furthermore, some of her fur items looked overwhelming which dyed in artificial color or printed with leopard pattern. These powerful items contained immanent meanings that are power and position which could express a role as an editor-in chief of Vogue USA.

  • The role of precise prediction of subsurface fluids and discrimination among them cannot be ignored in reservoir characterization and petroleum prospecting. A suitable rock physics model should be build for the extraction of valuable information form seismic data. The main intent of current work is to present a rock physics model to analyze the characteristics of seismic wave propagating through a cracked porous rock saturated by a three phase fluid. Furthermore, the influence on wave characteristics due to variation in saturation of water, oil and gas were also analyzed for oil and water as wet cases. With this approach the objective to explore wave attenuation and dispersion due to wave induce fluid flow (WIFF) at seismic and sub-seismic frequencies can be precisely achieved. We accomplished our proposed approach by using BISQ equations and by applying appropriate boundary conditions to incorporate heterogeneity due to saturation of three immiscible fluids forming a layered system. To authenticate the proposed methodology, we compared our results with White's mesoscopic theory and with the results obtained by using Biot's poroelastic relations. The outcomes reveals that, at low frequencies seismic wave characteristics are in good agreement with White's mesoscopic theory, however a slight increase in attenuation at seismic frequencies is because of the squirt flow. Moreover, our work crop up as a practical tool for the development of rock physical theories with the intention to identify and estimate properties of different fluids from seismic data.

  • This study considered the transition of changes in social status of the film through the discourse analysis of printed media, having been published since 6th revised film policy in 1987. For the purpose, Pierre Bourdieu's cultural sociology, or 'Field theory approach' was engaged as a theoretical background. On the basis of that theory, changes in social status was divided into expert and popular field. From 1988 to 2007, doctor's and master's theses on filmologie and the representative academic journal, "Film Studies" were examined with regard to area of expertise, and movie-related books with regard to popular one. This study demonstrated that the symbolic capital had inhered in the cinematic field along with specialization and diversification of analytic aspects, and the relation between the academic approach and political consideration had performed an important role in intellectualization of film.

  • In this study, we determined the characteristics and importance of market maven to today's fashion retailers. Market maven is defined as an individual who is highly involved in the marketplace and takes a role as an information diffuser. In order to identify market maven, a total of 415 data were collected from 30-40 consumers who purchased fashion items from the various types of retailers. The data were divided into three groups based on the average score of summated market maven's scale, and the high group was referred to as "market mavens." Results suggested that the market mavens existed in the fashion retailing market and presented the differences from the other two groups. The market maven group spent more and purchased more fashion items than the other groups. With respect to shopping behavior, the market maven group was more likely to browse and bargain hunt when shopping, and showed higher mean scores on impulse buying and overall satisfaction. In addition, market maven tended to purchase fashion items from different types of retailers including online channel. Accordingly, market mavens seemed to present common characteristics with heavy browser, recreational shopper, and/or multi-channel shopper. Market mavens showed shopping enjoyment characteristics when searching for market-related information from various retailers, hence this segment should be the essential target market in the multi-channel retailing environment.

  • Induction of DNA fragmentation of rat embryonic midbrain cells was studied to see whether apoptosis plays a role in OTA-induced microcephaly observed in cultured rat whole embryos during embryogenesis. We first cultured whole embryos (prepared from day 9.5 gestation rats) for 48 hrs with OTA and found that OTA induced microcephaly in cultured rat whole embryos. We also examined whether the microcephaly seen in cultured whole embryos is partially related to the increase of apoptosis of undifferentiated embryonic midbrain cells. Embryonic midbrain cells were prepared from day 12 gestation rat embryos, and cultured in the mixture media of Dulbecco's modified eagle's medium nutrient and Ham's F12 (1:1) containing 10% Nuserum, 100 $\mu\textrm{g}$/ml of streptomycin and 100 units/ml of penicillin for 96 hrs. Induction of DNA fragmentation was increased by 0.25-1 $\mu\textrm{g}$/ml OTA in a dose dependent manner in the embryonic midbrain cells. We also tested whether increase of apoptosis by OTA would be associated with change of apoptosis-related proteins (TNF-$\alpha$ and P$^{53}$ ) level in embryonic midbrain cells. OTA also increased TNF-$\alpha$ and P$^{53}$ levels. These results show that OTA induced microcephaly in cultured whole embryos and this effect may be at least a part due to the induction of apoptosis and apoptosis-related protein levels of undifferentiated embryonic midbrain cells.

  • With the rapid development in the field of unmanned aerial vehicles(UAVs) and drones, higher request to development of a surveillance system for a drone is putting forward. Since surveillance systems with fixed cameras have a limited range, a development of surveillance systems with a moving camera applicable to PTZ(Pan-Tilt-Zoom) cameras is required. Selecting the features for object plays a critical role in tracking, and the object has to be represented by their shapes or appearances. Considering these conditions, in this paper, an object tracking method with optical flow is introduced to track a tiny drone with a moving camera. In addition, a tracking method combined with kalman filter is proposed to track continuously even when tracking is failed. Experiments are tested on sequences which have a target from the minimal 12 pixels to the maximal 56337 pixels, the proposed method achieves average precision of 175% improvement. Also, experimental results show the proposed method tracks a target which has a size of 12pixels.

  • Prior research regarding the macro patterns of industry convergence has focused on the inter-industry patent network and cross-industry movements of products or services. This article provides a novel approach, according to which human resources embodying explicit and implicit knowledge and technologies are important media driving industry convergence. Drawing on GOMS data (2015-2019) and using information of university graduates' academic majors and their occupations, this article proposes an analytic strategy by which to understand the macro patterns and structural features of industry convergence. Specifically, we build unbalanced bipartite networks of major-industry (occupation) relations, and construct the measures of the industry's niche width and the measure of the average degree of convergence of majors that each industry is linked to. By crossing the two measures, we identify four groups of industries(occupations); specialist, generalist, partial convergence, and full convergence. The convergence group is composed of industries (occupations) that acquire human resources from a number of academic majors each of which plays a role of glue connecting several local industries.
