The purpose of this study is to have an opportunity to enhance the role of cultural intermediaries in the region as interest in the cultural media sector increased with the implementation of the Law for Promotion of Regional Culture. First, I discussed the need to pay attention to the local Cultural Intermediaries group as the background of the discussion, confirming that the existing research on the cultural mediation sector was focused on cultural workers in public institutions and government projects. Next, for the theoretical discussion, I reviewed the role of cultural intermediaries contributing to the production of meaning via the concept of cultural intermediaries by Pierre Bourdieu, and described that the mediation of regions and cultures began to emerge as an alternative to the existing centralized structure of cultural production in the context of Korea after the late 1990s. It was found that practices that mediate the region and culture were developed around the group of public artists and cultural activists and the intermediary group played a role in revealing various aspects of the region and dynamically constructing the local public sphere through these cultural practices. Lastly, local curator's cases (Space Beam, Space Imsi, Incheon Spectacle) were studied. The actual cases of activity were analyzed through the cultural practices by focusing on what alternative meanings had been produced in the region and how the region was represented. Each case showed the mediating activity that attempts to change the environment of life while sharing local issues with communities, projects that reconstructs the local professional art sector into a public sphere, and mediating activity that represents local daily culture and form networks through independent publications.

To date, detection of microbial populations in dairy products has been performed using culture media, which is a time-consuming and laborious method. The recently developed chromogenic media could be more rapid and specific than classical culture media. However, the newly developed molecular-based technology can detect microbial populations with greater rapidity and sensitivity than the classical method involving culture media and chromogenic media. This molecular-based technology could provide various options for monitoring the characterization of different states of bacteria and cells. Thus, it could help upgrade the processing system of the dairy industry so as to maintain the safety and quality of dairy foods. Among the various newly developed molecular-based technologies, flow cytometry can potentially be used for monitoring microbiological populations in the dairy industry if official international standards are available for this purpose. When omics technology would have biomarker identification, it could be regarded as the rapid and sensitive analytical methods. Methods based on PCR, which has become a basic technique in microbiological research, can be developed and validated as alternative methods for quantification of dairy microorganisms. This review discusses methods for monitoring microbiological populations in dairy foods and the limitations of these studies, as well as the need for further research on such methods in the dairy industry.

Contemporary society that is apt to be homogeneity because of the development of computer communication and mass-media desires to seek its own identity in native realm. Contemporary Korean architecture has endeavored continuous discussion and practice to keep its identity within the current tendency. The purpose of this study is to grope the alternative for genuine 'Koreaness' to analyse the variant trend of its characteristics 1990's. The variation of Korean society in 1990's that emphasize self-regulation and individual value has influence on the realm of architecture so much. The cognition of 'Koreaness' has changed with center in the individual and small -size design group, not present accommodation of past, but continuous research to find archetype of tradition which can play a decisive role of linking present and future on the foundation of past. Many attempts and practical works that express 'Koreaness' in 1990's are performed in the area of residence works that reflect Korean emotion and life-style directly. This change can be an answer to solve the problem of peculiarity and universality in 'Koreaness'. After 1960's the main theme of 'Koreaness' was traditional architecture form, but because of the induction of Postmodernism and at once its reflection and critical attitude with limit of formal duplication, which lost its meaning. In 1990's, research for spatial form as korean emotion and image has carried out and played an important part of original expression for 'Koreaness'

This study describes for the first time in Pinus genus a plant regeneration system via a combined pathway of somatic embryogenesis and organogenesis from immature seeds of radiata pine. Somatic embryos were obtained from embryogenic line 2162 of Pinus radiata D. Don on EDM basal medium containing $60{\mu}M$ ABA and 6% sucrose. The explants used for organogenesis experiments were either freshly collected somatic embryos or somatic embryos germinated for 1 week. Germination medium was half-strength LP medium, supplemented with 0.2% activated charcoal. Different induction periods and BA concentrations were assayed for shoot induction. After induction treatments, explants were elongated on the same medium used for germination stage. Rooting medium was quarter-strength LP medium supplemented with three different auxin treatments: $1.5mg\;L^{-1}$ 1-naphthalene acetic acid (NAA), $1.5mg\;L^{-1}$ indole-3-butyric acid (IBA) and $1mg\;L^{-1}$ IBA with $0.5mg\;L^{-1}$ NAA (MIX). The effect of the photon flux ($120mmol\;m^{-2}\;s^{-1}$ and darkness) in the first week of the explants in the rooting media was also tested. This methodology could offer an alternative to overcome some problems associated with somatic embryogenesis such as the seasonality of embryogenic tissue (ET) initiation or a low embryo production from the ET, a particularly important issue in the case of genetically transformed ETs.

Building Information Modeling(BIM) is rooted in the economic and functional advantages of maturing from paper-based 2D drawings. The paper-based design and construction drawings are typical production from BIM and using the drawing under BIM environment is needed because there is not an alternative media instead of paper-based drawings. However using the 2D drawing process based on 2D CAD for BIM environment directly has difficulties because there are significant differences in data structure between CAD and BIM. CAD is based on traditional drawings as a whole while BIM is focused on individual objects and providing various levels of information associated with the objects. It can be an obstacle to move from 2D CAD to BIM that we don't have a standard or guideline for BIM. Futhermore, the complexity of drawing in representation would be the obstacle too, so the solution is discussed in the research based on the case of Samoo Architects and Engineers.

Soil biofiltration is an environmentally-sound technology for elimination of VOCs, odorous and NOx compounds from a low concentration, high volume waste gas streams because of its simplicity and cost-effectiveness. This study was performed to evaluate effect of removal of gaseous NOx using a soil and a yellow soil. Over $60\%\;and\;48\%$ of NOx from a soil and a yellow soil was removed at the inlet NO concentrations of $423\~451$ppb, respectively. The bio-filter using a soil media was capable of purifying NOx with a different natural processes. Although some of the processes are quite complex, they can broadly be summarized as adsorption into soil pore water, and biochemical transformations by soil bacteria. When the filteration bio-reactor was applied to a soil and a yellow soil, effective NOx removal was obtained for several times and months. These results show that a soil biofilter can be of use as an alternative advanced NOx treatment system.

Bone marrow derived mesenchymal stem cells (BMSCs) are largely studied for their potential clinical use. But it is hard to get enough number of those cells for clinical trials and give serious pain to the patients. Adipose tissue is derived from the embryonic mesenchyme and contains a stroma that is easily isolated with large amount. This cell population (adipose derived stem cells: ADSCs) can be isolated from human lipoaspirates and like MSCs, differentiate toward the osteogenic, adipogenic, myogenic and chondrogenic lineages. To confirm whether adipose tissue contains stem cells, the ADSCs extracted from omental or subcutaneous fat tissue were expanded during third to fifth passages. The phenotype of the ADSCs was identified by the conventional cell surface markers using flow cytometry: positive for CD29 and CD44, but negative for CD34, CD45, CD117 and HLA-DR that similar to those observed on BMSCs. The ADSCs were able to differentiate into the osteoblast or adipocytes with induction media. Finally, ADACs expressed multiple CD marker antigens similar to those observed on BMSCs and differentiated into osteoblast, adipocyte. With this, human adipotissue contains multipotent cells and may represent an alternative stem cell source to bone marrow-derived MSCs.

With increasing interest in ubiquitous computing technology, an infrastructure for the short-distance wireless communication has been extended socially, bringing spotlight to the security system using the image or location. In case of existing security system, there have been issues such as the occurrences of blind spots, difficulty in recognizing multiple objects and storing of the unspecified objects. In order to solve this issue, zone-based location-estimation search system for the image have been suggested as an alternative based on the real-time location determination technology combined with image. This paper intends to suggest the search service for the image zone-based location-estimation. For this, it proposed the location determination algorism using IEEE 802.15.4/ZigBee's RSSI and for real-time image service, the RTP/RTCP protocol was applied. In order to combine the location and image, at the event of the entry of the specified target, the record of the time for image and the time of occurrence of the event on a global time standard, it has devised a time stamp, applying XML based meta data formation method based on the media's feature data based in connection with the location based data for the events of the object. Using the proposed meta data, the service mode which can search for the image from the point in time when the entry of the specified target was proposed.

In this study, we applied DRASTIC and SINTACS models for the assessment of groundwater vulnerability to Buyeo-eup area in Buyeo-gun, Chungcheongnam-do, Korea. Currently, DRASTIC model is a main tool for the assessment of groundwater vulnerability, which has been widely applied for the multiple purposes related to local developments, construction projects, groundwater investigations, etc. since 1980s. Because DRASTIC model has been the sole tool used for the domestic environment, there has been doubt about the degree of reliability of the model, and a benchmark model has been sought by the many practitioners. The objective of this study is to check the applicability of SINTACS model to domestic environment, which is the first attempt in Korea as far as authors understand. The comparative results show that the DRASTIC assessment underestimates groundwater vulnerability of the aquifers composed of fractured bedrocks while that from the SINTACS model is relatively higher. Through this study, it is expected that SINTACS model serves as a reasonable alternative of DRASTIC model where the subsurface is composed of more than two different media such as fractured rocks and alluvium.
