Due to changes such as those stemming from the onset of the fourth industrial revolution, it is expected that industrial complexes will transform from being spacious structures into smaller, integrated complexes. Green parks, which are also a type of infrastructure within industrial complexes, also require planned direction suited to the changing environment. The planned directions of green parks in new industrial complexes were examined and surveys were conducted on industrial complex workers. Preferred functional arrangement, importance, and satisfaction levels of green ratios, preference of compound facilities linked to parks, appropriate dimensional greening methods were all surveyed across 1,035 businesses. Results of the survey exhibited that there was high awareness on the importance of building green areas, but it was found that current greenery levels were insufficient. There was a high rate of responses indicated that dimensional greening is required in building-type industrial spaces, and preferences for rooftop greenery, stair-type greenery, and atrium greenery were also high. There were many opinions that it is necessary to integrate cultural facilities, exhibition and educational facilities, commercial facilities, parking lots in parks. Furthermore, it was found that it is necessary to provide pathways for bikes and pedestrians, rather than those for vehicles, and to connect them with the green parks. This study stopped short of exploring the directions for which green parks should aim in new industrial complexes with changes in the industrial environment. In the future, more concrete plans on green park planning techniques according to the spatial characteristics and structures of new industrial complexes will be necessary.

An enzyme ${\beta}$-galactosidase or ${\beta}$-galactohydrolase [EC3.2.1.23], commonly called lactase, mediates galacto-oligosaccharide (GOS) synthesis under conditions of high substrate concentrations. Also, lactase hydrolyzes ${\beta}$($1{\rightarrow}4$) lactose into glucose and galactose, the latter is successively transferred to free lactose to make various oligosaccharides via transgalactosylation. GOS is non-digestible to human digestive enzymes and has been used as a functional prebiotics. Among the 24 lactic acid bacteria (LAB) strains used, Lactobacillus paracasei YSM0308 was selected based on its exhibition of the highest ${\beta}$-galactoside hydrolysis activity, and the crude lactase was prepared for examination of reaction conditions to affect the GOS synthesis. Lactase activity was measured with a spectrophotometer using ONPG (o-nitropheyl ${\beta}$-D-galactopyranoside) method. Lactase activity was not detected in the culture supernatant and was mostly present in the cell pellet after centrifugation. Activity of the crude lactase preparation ranges from102 to 1,053 units/mL, with the highest activity determined for L. paracasei YSM0308. Optimal conditions for GOS synthesis are as follows: concentration of whey powder, pH, temperature, and time were 30%, pH 6.5-7.0, $30^{\circ}C$, and 4 h, respectively. The final GOS concentration was 19.41% (w/v) by the crude YSM0308 lactase, which was obtained from strain YSM0308 grown in the 10% (w/v) reconstituted whey-based medium.

In an effort to obtain foundational data required to evaluate the therapeutic effect of educational insect rearing, this study surveyed current educational pet insect rearing practices in Korea and examined the expected psychological effects from participating in the activity. Data were collected from those who visited the special insect exhibition in May 2013 using a self-reporting survey. The results indicated that 48.3% of the responders had experienced insect rearing, and that rhino and stag beetles were the most commonly reared insects. Most of the respondents (83.1%) reported they were not currently rearing any insects, which suggested that insect rearing tends to be a one-time experience. Expected psychological effects could be divided into emotional (56.3%) and cognitive (41.8%) effects, and these varied by age and gender. The differences in expected psychological effects were particularly clear between adults and adolescents, the latter of whom were the main participants in the activity. It is therefore necessary to develop standardized manuals and care programs for more diverse insect species with which to help keep up consumer interest in educational insect rearing. These efforts will help champion the psychotherapeutic effects of educational pet insect rearing and enhance its role as a learning aid.

The video production, as a recording data about the archeological survey, has advantages to be visualized in actuality and historical fact presented objects with elements such as moving images, audio(voice) and text(subtitle). While the report with text and images such as photographs and drawings does not present exactly, the video production can record a concrete excavation process to be difficult of represent with former media. To make a practical use the video production in archeological surveys, the use dimension should be expanded to the entire archeological excavations and the shooting and editing work should be done by those video production-specialized staffs. Ultimately, when this video production device is used but also for the survey purposes but also for the education, exhibition, and even commercial purposes, it can have the substantial meaning as a survey tool.

For the efficient management of church documentary for religious reasons, including their historical and cultural values, the church archives should be excellently managed. However, the lack of understanding and consideration of the church records and archives makes it very difficult to have an actual grasp of its status and practical supports, such as budget and personnel, for records management. In this study, literature reviews and current status of domestic Protestant church archives, user survey of Saemoonan Presbyterian church and interviews of church archives records officer were carried out. Based on the results of the study, three parts of the proposed plan of the Saemoonan Presbyterian Archives were suggested. Education, exhibition, publication, and promotion of the church's archival services will help redirect the roles and values of the archives, which will make it an essential part of the church.

Recently, many New Han-oks have been constructing in all over the country to popularize as a type of green house. But, achievement of thermal performance of external wall is still the very important issue to become popular. Purpose: The purpose of this study is to verify the thermal performance level of modern New Han-ok through Temperature Difference Ratio inside(TDRi) analysis at corners of the external wall in Han-ok. Method: To achieve this goal, measurements were carried out in 12 Han-oks(experimental mock-up(1), exhibition Han-ok(1), happy village Han-oks(10)) by taking a infra-red thermography using thermal video system. Following are analysis items about connection joint between wall and wood columns of external wall conditions; the part between external wall and external wall(2D), external wall and ceiling(or floor)(2D), 2 external walls and ceiling(or floor)(3D) and so on. Result: It was analyzed that the probability of condensation at most of connection joint appear high and TDRi of 3D corners is higher than that of 2D corners in general. It means that the development of construction techniques about connection joint between wood columns and external wall is still required. The results of this study may be used to improve the construction technology of new Han-ok and as a basis for the specifying the desired thermal comfort environment of dwelling.

Many types of services appear in a ubiquitous environment promulgated by the evolution of web service technology with the advances in wireless network technologies and mobile computing devices. These services differ according to their location environments, such as home, office, airport, and exhibition. It is required that a different set of services dynamically drops into the mobile user's device depending on their context and the distributed localized services are efficiently managed to seamlessly provide these localized services to the user. This paper proposes an Autonomic Service Composition System (ASCS) to provide useful services to the user with minimal or no effort for service selection. ASCS seamlessly installs the programs of localized services in the user's mobile device. It automatically provides localized services to users that are in the local service zone. Also ASCS can manage distributed localized services remotely and efficiently. ASCS is composed of a Remote Manager, Service Gateway, and Mobile Device. The prototype implementation uses 802.11b Wireless Network and Bundles using the OSGi Framework.

This research analyzed characteristic changes in trading areas and the success factors of popular fashion trading areas (Garosu-gil, Dongdaemun, and Itaewon). This research adopts a social network analysis method to semantically analyze trading areas. Articles on the three fashion trading areas were located through KrKwic software to extract keywords and calculate word frequency. Keywords with high frequency were placed through NodeXL software to identify relationships among keywords. Researchers created a network of relationships among trading areas and between past and present of trading areas to analyze and visualize. In the past (2008-2009), the trading areas of Dongdaemun, Garosu-gil and Itaewon were placed horizontally with a limited number of shared keywords between them. However, the three trading areas retain diverse rage of keywords and an organic realtionships five years later (2013-2014). Compared to the past, all three areas see the emergence of relevant fashion keywords such as 'designer', 'design', 'brand'. Additional cultural keywords such as 'culture/art/performance', 'exhibition', and 'event' have commonly appeared and imply that related industries are an important factor as well. Fashion companies that consider evaluating areas for a new store opening need to understand the trading area characteristics and select the most suitable area. In addition, it is necessary to equip the trading area with basic fashion elements as well as relavant industry when the government tries to develop fashion trading areas.

Stem rot symptoms of Eupatorium lindleyanum occurred sporadically in the herb exhibition field at Hamyang-gun Gyeongsangnam-do Agricultural Research and Extension Services in Korea. The typical symptom included water-soaking on the main stem, rotting, wilting, and blighting, which eventually leads to death of the plant. The sclerotia, white to brown, globoid with size of 1-3 mm, were formed over lesions and surface soil line. The optimum temperature for mycelial growth and sclerotia formation was $30^{\circ}C$ on PDA. The typical clamp connections were observed in the hyphae of the fungus grown on PDA. Mycological characteristics and pathogenicity to host plants indicated that the infected fungus was Sclerotium rolfsii Saccardo. This is the first report of stem rot on Eupatorium lindleyanum caused by S. rolfsii in Korea.

Dynamic modeling was used to predict the Pseudomonas spp. concentration in Alaska pollack under dynamic temperature conditions in a programmable incubator using Euler's method. The model evaluation showed good agreement between the predicted and measured concentrations of Pseudomonas spp. In the simulation, three kinds of distribution path were assumed: consumers buying from a distribution center (A), manufacturer (B), or direct market (C). Each of these distribution paths consists of six phases: shipping, warehousing/shipment, warehousing/storing, processing, market exhibition, and sale/consumption. Sensitivity analysis of each phase was also implemented. The Pseudomonas concentrations and sensitivities ($S_k$) at the terminal phases of the three paths were estimated to be (A) 11.174 log CFU/g and 10.550 log $S_k$, (B) 10.948 log CFU/g and 10.738 log $S_k$, and (C) 8.758 log CFU/g and 9.602 log $S_k$, respectively. The sensitivities indicated that path A has the highest risk of failure in managing the relevant phases.
