We analyzed antioxidant and physiological activities to investigate the functional effects of ethanol extracts of Anomala albopilosa imago and A. albopilosa larva. In order to effectively screen for anti-inflammatory agents, we first investigated the antioxidant activities such as DPPH radical scavenging capacity, superoxide radical scavenging capacity, xanthine oxidase inhibitory activity, and nitric oxide scavenging capacity of the A. albopilosa extracts. By the screening system, we found that A. albopilosa extracts had antioxidant activity which increased with increments of the extract concentration. Moreover, we examined the inhibitory effect of the A. albopilosa extracts on the production of anti-inflammatory factors that the nitric oxide (NO), inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2) and prostaglandin $E_2\;(PGE_2)$ production activated with LPS ($1{\mu}g/mL$) in murine macrophage cell line RAW 264.7. A. albopilosa extracts potentially inhibited the iNOS and COX-2 in a dose-dependent manner. The inhibition of iNOS activity was correlated with the decrease in nitrite levels. Additionally, the $PEG_2$ production is markedly inhibited after a treatment with the A. albopilosa extracts.

The citrus industry represents a major sector of agribusiness in Jeju successfully nurtured by the local governmental farm bureaus for the past three decades. However, in the face of increasing imports effected under the international free trade agreement, the continuous economic viability of the island’s citrus industry is no longer assured. Thus, it entails exploration and development of new agribusiness potentials that are supplemental and/or alternative to the citrus industry. In this presentation, I will discuss two projects of such potentials. (i) Under the tripartite collaboration among Kumho Life and Environmental Science Laboratory, Cheju National University and South Jeju County, genetically engineered turfgrass cultivars possessing both herbicide- and shade-tolerances (gene pyramiding) are currently at final phase of phenotype evaluations and environmental safety assessments. (ii) Fig fruits with longer shelf-life are being developed with support from Jeju HiTech Industrial Development Institute (HiDI) and at its initial phase of development.

The 10 species of marine green algae was collected from Jejudo(Island) in Korea. Methanolic and aqueous extracts were prepared and screened for inhibition activities against tumor cell growth. Of the tested samples, the sea staghorn (Codium fragile) aqueous extract (CFAE) showed the highest activity on CT-26 cell growth. Therefore, CFAE was selected for further experiments and the possibility to induce apoptosis by the CFAE was investigated. Flow cytometric analysis revealed that it dose-dependently increased apoptotic cells with hypodiploid DNA contents in CT-26 cell line. These results indicated that CFAE can suppress the growth of CT-26 cells through apoptosis. The CFAE decreased the protein expression of anti-apoptotic Bcl-xL and led to the activation of caspase-3 and -7. A crude polysaccharide was separated from CFAE and it mainly constituted with 61.2% galactose and 30.5% arabinose as analyzed by high performance liquid chromatography (HPLC).

The use of Hi-Tech in cultural heritage preservation and the promotion of cultural heritage values in general, particularly artifacts, opens new opportunities for attracting tourists while also posing a challenge due to the need to reward high-quality excursions to visitors historical and cultural values. Building Information Modeling (BIM) and Hi-Tech in new building management have been widely adopted in the construction industry; however, Historic Building Information Modeling (HBIM) is an exciting challenge in 3D modeling and building management. For those reasons, the Scan-to-HBIM approach involves generating an HBIM model for existing buildings from the point cloud data collected by Terrestrial 3D Laser Scanner integrated with Virtual Reality (VR), Augmented Reality (AR), contributes to spatial historic sites simulation for virtual experiences. Therefore, this study aims to (1) generate the application of Virtual Reality, Augmented Reality to Historic Building Information Modeling - based workflows in a case study which is a monument in the city; (2) evaluate the application of these technologies to improve awareness of visitors related to the promotion of historical values by surveying the experience before and after using this application. The findings shed light on the barriers that prevent users from utilizing technologies and problem-solving solutions. According to the survey results, after experiencing virtual tours through applications and video explanations, participant's perception of the case study improved. When combined with emerging Hi-Tech and immersive interactive games, the Historic Building Information Modeling helps increase information transmission to improve visitor awareness and promote heritage values.

DNA extracted from ancient bones of Cervidae animals was examined to identify the species and to determine the phylogenetic relationships to those from extant cervids. Abundant ancient bones were excavated from Kumsung archaeological site in Jeju Island, Korea, and were identified as Cervidae animals based on morphological features of their antlers and lower mandibles. Their mitochondrial DNA (mtDNA) control region (CR) was partially sequenced and subsequently compared with those previously reported in database. The results confirmed that the ancient sequences are lineage of Cervidae. On the phylogenetic trees constructed using the sequence diversity of the CR sequences of family Cervidae, the ancient DNA sequences were found on distinct clusters. The ancient sequences were located in the subfamily Capreolinae cluster, and six ancient sequences were closely related to those of extant Korean roe deer in Jeju Island and Korean Peninsula. Consequently, the results of this study suggest that the roe deer inhabited Jeju Island in ancient times. However, there is no evidence for the existence of subfamily Cervinae, including Sika deer, while it has been described in several historical records. The results suggest that this finding could contribute to understanding of the origin and phylogenetic relationships of extant and ancient roe deer on Jeju Island.

There are a variety of alternative products in the computer markets. A tablet PC, which is a small type of computer, is expanding its market share as an independent type of computer products. The purpose of this study is to find out what the factors are that led to the success of the tablet PC. A research study was carried out on the intention to use of tablet PCs by consumers. The factors that affect the intention to use of tablet PCs users were structured on the basis of attitude theory. According to the one-dimensional theory of attitude, cognitive factors affect the affective factors, which in turn affect conative factors. In the study, the relations between each dimension were set up. The hypothesis was tested by structural equation modeling. The test results are as follows. First, the values and satisfaction that the owners of tablet PCs feel from the products and the positive comments on the products from their nearby acquaintances affect in a positive way how much they like their products. Second, the products surrounding the tablet PCs did not affect the intention to use of the products. Third, the product favorability that the owners of tablet PCs feel affects the intention to use in a meaningful way. The results of the research also show that hi-tech products such as tablet PCs affect their attitude after they buy and use the products. This attitude affects intention to use of the products. The managers of companies that produce hi-tech products should consider the cognitive and affective aspects of the product owners when manufacturing and marketing products.
