The starting point of this study is the concerning of simple behavioral pattern that whoever enters the inner space with taking off his shoes should go out from the position where he laid his shoes. The using of Ondol (floor heating room) and Maru (lifted wood floor) had changed the architectural space from chair-sitting to floor-sitting space, and it also made the behavior of taking off the shoes at the entrance of building and stepping on the lifted floor. This simple behavior has possibility to make lots of changes to the culture of architectural design. With this noticeable point, this paper is talking about the cultural feature of Korean traditional architecture, especially about the influence of tanking off and putting on shoes. The matter of shoes has changed diverse aspects of building and layout planning. It maximized the difference between front and rear part of building and characterized the lateral extension of Korean traditional house. The ritual space also had evolved from chair-sitting to floor-sitting space according to the type of ritual behavioral pattern. The change on the single building level had influenced on the layout planning of architectural complex. For examples, the parallel layout of ChangDeok-gung palace and the long sequential process to the main pavilion of Buddhist temple are the result of the matter of shoes. And NuGak(樓閣), the double-storied pavilion, on the axis of entering sequence's node is one of the unique planning elements that makes possible to go through the building without taking off the shoes and also makes upper level space for staying. In short, Korean traditional architecture that has the chair-sitting spatial origin of the East Asian cultural sphere has pursued new architectural issues and planning methods according to evolution to the floor-sitting culture.

The present study was carried out to determine the effects of lighting directions and light intensities on the growth of in vitro plantlets of strawberry, potato and lily. The growth of plantlets was affected by two different lighting systems, downward and sideward lighting system. There were no difference for the plantlets of strawberry regardless of lighting directions. However, leaf area, fresh weight and dry weight have increased as the light intensity increased. Also, plant height and root length on node culture of potato decreased at high intensity of the sideward lighting, while thickness of stem and root was thicker, fresh weight and dry weight were heavier, and leaf area was increased. Also, bulblet formation on scale culture of lily has been abundant, and fresh weight and dry weight were increased. Thus, the sideward lighting system which loaded three stories for culture vessels with raising light intensity into culture vessels instead of conventional downward lighting system promoted growth and raised the efficiency of production of high quality microplant.

This study was aimed to proliferate Gentiana axillariflora Leveille which is one of the important medicinal and ornamental plants, by establishment of multiple shoot formation and embryogenesis through tissue culture technique. Callus was formed on MS (Murashige and Skoog) medium supplemented with 2,4-D, CPA, but not formed with BAP. The addition of 2,4-D 2 mg/ l into the medium was effective for callus formation and the rate of callus formation was about 90%. Somatic embryos were obtained on MS medium for two months. When callus was cultured on MS medium with combination treatment of 2,4-D 0.5 mg/ l and BAP 0.5 mg/ l, the number of embryo formed was better than that of other single or combination treatments and the total numbers of embryo a were 18.8 (number of total embryo/number of explants incubated = 753/40) at mean. Callus induction from stem and node explants was increased by addition of TDZ 2 mg/ l in the presence of 2,4-D 2 mg/ l, respectively. The best result about the differentiation of shoots was obtained on MS medium added BAP 2 mg/ l from node culture. Multiple shoots from shoot apex were induced on MS medium containing BAP 1 mg/ I and TDZ 1 mg/ l , BAP 2 mg/ l and TDZ 1 mg/ l. The number of multiple shoots per one explant was above seventy plants. It was the most effective regeneration system for rapid multiplication of Gentiana axillariflora Leveille.

Intermedia refers to the convergence of media. The advance of intermedia has not only facilitated the delivery of brand messages in contemporary fashion shows but also facilitated interactive communication. This study investigated the mediating roles played by various media in fashion and fashion shows, focusing on the phenomenon of intermedia in contemporary fashion shows. To investigate the impact of intermedia on contemporary fashion shows, we conducted a social network analysis-a promising approach for research into fashion trends. Analyzing 159 fashion-related articles published in the 2000s, we extracted intermedia-related words (n=253). The relation-ships between keywords made an analysis of between centrality, and cluster variables applied Clauset-Newman-Moore by using KrKwic and NodeXL programs. The results of the between centrality analysis indicated that the most important factors in contemporary fashion shows are "models" and "stages." We found that the impacts of intermedia on contemporary fashion shows can be divided into four categories: "model performance," "symbolic stage management," "new media utilization," and "convergence in arts." Our analysis thus identified considerable synergy between the characteristics of intermedia and contemporary fashion shows. These results have found intermedia-related commonalities in intermedia and fashion show, and this might increase customer interest in fashion, a positive outcome for the fashion industry.

Protocols for in vitro conservation was developed for Coleus forskohlii. Plants maintained both in field served as explant source. Shoot tips and single node cuttings were used to optimize protocols for in vitro multiplication. MS basal medium supplemented with $0.54\;{\mu}M$ naphthalene acetic acid (NAA) and $8.87\;{\mu}M$ benzy-ladenine (BA) induced multiple shoots in shoot tips and nodes. Shoot multiplication was amplified with a gradual decrease of BA concentration, leading to its final omission after 4 months. Concomitant rooting on multiplication media enabled successful establishment extra vitrum. For in vitro conservation studies, experiments were carried out with 2-3 week maintained in vitro plants under standard and reduced culture conditions (SCC, RCC). In vitro plants could be successfully conserved in full strength MS medium (FMS) under SCC for 6 months without subculture with full potential to regenerate, producing viable shoots and nodes. The root production remained unaffected due to conservation, showing high rooting activity in mannitol and low temperature treatments. Preset low temperature (15 and $10^{\circ}C$) and reduction in media constituents does not appear to favour conservation, although the former accomplished conservation levels equal to (FMS) under SCC.

The research is to identify social networks of problems that have an influence on the quality of ageing people's lives by using social network analysis, based on the premise that there are differences in networks of ageing problems in urban and rural areas. From analyzing network of ageing people's problems using NodeXL, vertices in the networks of both urban and rural areas are well-connected. For urban areas, financial poverty is the core problem related to the quality of life. It has direct connections with illness and health, family responsibility, housing, role loss in community, and employment, which have positive or negative interactions with the quality of older people's lives. For rural areas, on the other hand, role loss in community is the major problem. It has direct connections with the elderly abuse, financial poverty, leisure activity, divorce, isolation and loneliness from society, education, and suicide. As a result, the research shows that the problems of ageing people have strong linkages and interactive effects with a structure of network, and the networks are different depending on types of places for living.

Wireless sensor network technology is becoming increasingly important with the advancement of the Fourth Industrial Revolution. Consequently, various protocols such as LEACH, PEGASIS, and EEACP have been developed in an attempt to increase energy efficiency. However, the EEACP protocol still has room for improvement in terms of energy consumption during transmission. Particularly, inefficient paths associated with data reception settings may compromise the network's survivability. The proposed A-EEACP protocol optimizes data transmission direction around the sink node to reduce energy consumption and enhance the network's survivability.
