  • A land cover map provides basic information to help understand the current state of a region, but its utilization in the ecological research field has deteriorated due to limited temporal and spatial resolutions. The purpose of this study was to investigate the possibility of using a land cover map with data based on high resolution images acquired by UAV. Using the UAV, 10.5 cm orthoimages were obtained from the $2.5km^2$ study area, and land cover maps were obtained from object-based and pixel-based classification for comparison and analysis. From accuracy verification, classification accuracy was shown to be high, with a Kappa of 0.77 for the pixel-based classification and a Kappa of 0.82 for the object-based classification. The overall area ratios were similar, and good classification results were found in grasslands and wetlands. The optimal image segmentation weights for object-based classification were Scale=150, Shape=0.5, Compactness=0.5, and Color=1. Scale was the most influential factor in the weight selection process. Compared with the pixel-based classification, the object-based classification provides results that are easy to read because there is a clear boundary between objects. Compared with the land cover map from the Ministry of Environment (subdivision), it was effective for natural areas (forests, grasslands, wetlands, etc.) but not developed areas (roads, buildings, etc.). The application of an object-based classification method for land cover using UAV images can contribute to the field of ecological research with its advantages of rapidly updated data, good accuracy, and economical efficiency.

  • Background: One of the important factors in the prognosis of chronic hepatitis B patient is the degree of replication of hepatitis B virus (HBV). It has been known that HBV DNA polymerase plays the essential role in the replication of HBV. HBV DNA polymerase is composed of four domains, TP (Terminal protein), spacer, RT (Reverse transcriptase) and RNaseH. Among these domains, tyrosine, the $65^{th}$ residue of TP is an important residue in protein-priming reaction that initiates reverse transcription. If monoclonal antibody that recognizes around tyrosine residue were selected, it could be applied to further study of HBV replication. Methods: To produce TP-specific scFv (single-chain Fv) by phage display, mice were immunized using synthetic TP-peptide contains $57{\sim}80^{th}$ amino acid residues of TP domain. After isolation of mRNA of heavy-variable region ($V_H$) and light-chain variable region ($V_L$) from the spleen of the immunized mouse, DNA of $V_H$ and $V_L$ were obtained by RT-PCR and joined by a DNA linker encoding peptide (Gly4Ser)3 as a scFv DNA fragments. ScFv DNA fragments were cloned into a phagemid vector. scFv was expressed in E.coli TG1 as a fusion protein with E tag and phage gIII. To select the scFv that has specific affinity to TP-peptide from the phage-antibody library, we used two cycles of panning and colony lift assay. Results: The TP-peptide-specific scFv was isolated by selection process using TP-peptide as an antigen. Selected scFv had 30 kDa of protein size and its nucleotide sequences were analyzed. Indirect- and competitive-ELISA revealed that the selected scFv specifically recognized both TP-peptide and the HBV DNA polymerase. Conclusion: The scFv that recognizes the TP domain of the HBV DNA polymerase was isolated by phage display.

  • The Arbitration Act of Korea entered into force on December 31, 1999. It was modeled after the UNCITRAL Model Arbitration Law to meet the goal of the internationalization of the arbitration system of South Korea mainly in terms of the System (Alternative Dispute Resolution) Act. In general, a hearing of arbitration is made up of an arbitrator, claimant, and respondent. This is accomplished in a single core. The advantages of arbitration are low cost and confidentiality. In addition, there is the participation of experts and rapidity with a single core agent. However, under the current Arbitration Act, there is no provision expressly relating to the qualifications of arbitrators. This should be accomplished by the arbitration act enforcement ordinance. Following specific details of the 'party' in conjunction with all the provisions of the Arbitration Act, Article 1 should be revised in a timely manner so that "conflict of private law" covers cases in which a dispute between the parties is desirable. In addition, in Article 3 the phrasing of "also dispute 'judicial'" should be revised to over disputes between parties. Furthermore, the provisions of Article 40 are described in the Supplement and so it is preferable to address Supplementary Delete. In addition, this study will analyze ADR in Japan and present a plan to establish a law to resolve disputes outside of court in that country. Therefore, the objective of this study is to assist in the study of legislating fundamental law for alternative dispute resolution. In spite of this, there are many in business and academia who would like to modify the arbitration system in South Korea to improve its function. There is much interest in accomplishing this,so proposals for legislation should continue to be made.In order to accomplish this, the arbitration systems of developed countries such as the United States can be used as a model. It can be seen that despite the idea that the parties involved engage in arbitration autonomously, many elements of the process from the selection of the arbitrator of the arbitral tribunal are specified in legislation and thus it is necessary to develop legislation that will allow arbitration to perform its intended function. Any given arbitral tribunal can be specialized, typically in a case an arbitrator who is an expert in the field is selected. This helps to avoid complaints concerning the results of the arbitration. In the case of international arbitration, however, this provision is often not employed and instead it is necessary to provide a Schedule and Supplement concerning international arbitration. Finally, the promotion of the enactment of the Arbitration Law Enforcement Ordinance must be a top priority in order to ensure proper implementation of the arbitration law.

  • Presidential TV debates serve as an important instrument for the general viewers to evaluate the candidates’ character, to examine their policy, and finally to make an important political decisions to cast ballots. Every words candidates utter in the course of entire election campaign exert influence of a certain significance by delivering their ideas and by creating clashes with their respective opponents. This study focuses on the conceptual venue, coined as ‘stasis’ by ancient rhetoricians, in which the clashes take place, and examines the words selection made by each candidates, the manners in which they form stasis, call for evidence, educate the public, and finally create a legitimate form of political argumentation. The study applied computer based content analysis using KrKwic and UCINET software to analyze semantic networks among the candidates. The results showed three major candidates, namely Lee Myung Bak, Jung Dong Young, and Lee Hoi Chang, displayed separate patterns in their use of language, by selecting the words that are often neglected by their opponents. Apparently, the absence of stasis and the lack of speaking mutual language significantly undermined the effects of debates. Central questions regarding issues of North Korea failed to meet basic requirements, and the respondents failed to engage in effective argumentation process.

  • As coming smart computing era, the government and leading telecommunication companies have actively supported the development of mobile applications. However, since it is processed apart from the characteristics of small businesses, policy problems and support ways have continuously been pointed out. In this study, we selected priority of support project for the activation of the mobile application development, then proposed support ways for the success of small development business. Firstly, we researched the mobile business literatures, support projects and policy trends of the Korean government, academia and private sector. Next, we developed the activation model for small development business by synthesizing of support projects, literatures and expert group interviews. Based on this model, we selected priority of support projects according to AHP (Analytic Hierarchy Process) analysis results. In conclusion, we categorize the five support ways for the activation of mobile application development. We are expecting that these support ways will be useful to the development of effective policies and selection of detail tasks for the support of small business or developers.

  • The technique for order preference by similarity to ideal solution (TOPSIS) is regarded as a classical method of multiple attribute decision making (MADM), often used to solve various decision-making or selection problems. It is based on the concept that the chosen alternative should have the shortest distance from the positive ideal solution and the farthest distance from the negative ideal solution. The TOPSIS can be applied to a design process for carrying out multi-objective shape optimization wherein the best and worst alternatives are to be decided. In this paper, multi-objective shape optimization using the TOPSIS and Rational Bezier curve was applied to the funnel of a cathode-ray tube (CRT). In order to minimize the weight and first principal stress, a new multi-objective shape optimization methodology is proposed, wherein the relative-closeness coefficients of the TOPSIS are defined as the performance indices of a multi-objective function and evaluated by response surface models. This methodology enables the designer to decide on the best solution from a number of design specification groups by examining the various conflicts between the weight and the first principal stress.

  • Bark is a general medium for potted Cymbidium in Korea, but it is difficult to shake off or eliminate the medium from the roots before exporting the potted plants. This working process can injure the roots and then deteriorate plant marketability. This study was carried out to select the optimum medium easier to eliminate from the roots instead of bark and the optimum amount of applied fertilizer to improve the plant growth. Cymbidium young plants 'Honey Hot' and 'Desert Look' were planted in pots with bark, cocochip, and peatmoss. The plants were treated with 2, 4, and 6 g of slow release fertilizer. The plant growth characteristics were investigated in the first and second years during production period of three years. The medium characteristics and mineral nutrient content of the leaves were also examined in the second year. In the first year, the plant growth of 'Desert Look' was improved in all peatmoss treatments more than bark. 'Honey Hot' showed the highest plant growth values in the bark treatment. In the second year, the plant growth of the two cultivars was improved in peatmoss. Cocochip treatments showed the lower plant growth values than bark and peatmoss in the first and second year. There was no significant difference among fertilizer amounts in all the media. The higher CEC values of peatmoss medium resulted to higher capacity to hold more nutrients than bark, and the nutrient retention of the peatmoss improved the plant growth. The higher K and Ca contents in the leaves would contribute to improve the plant growth. Consequently, it would be possible to use peatmoss instead of bark for Cymbidium young plants, but there must be always attention to appropriately water the medium and manage the moisture.

  • There is a need to develop diverse cultivation species with reference to the favorites and farming experiences of allotment garden participants, in addition to the crops being cultivated in the gardens. In this study, therefore, a survey on the status of cultivation and the demand for herb crops for the garden participants was conducted. Current trend of the programmes related to allotment garden for city dwellers, executed by various relevant organizations was analyzed. A questionnaire was accomplished by adult participants experiencing farming in allotments. Likewise, interview with farm proprietors was conducted. The results showed that the number of crop species cultivated in allotments was about ten species. The purchase of seeds and nursery plants was mainly dependent on the farmland proprietors. The selection of the crops was made by both wife and husband. The status of herb utilization indicated that 5.7% of participants were cultivating or had cultivated herb plants. Sixty-two percent of participants were not cultivating herb plants because they did not know how. The purposes of using herbs were for medicine and beauty (22.0%), for spices (22.0%) and for enjoyment (29.0%). Thirty-four percent (34.0%) of participants were interested or would like to use the herbs in the future for medicine and beauty, 39.0% for spices and 31.7% for enjoyment. It is expected that the demand for herbs would increase. Also, 78.3% of participants had the intension or had taken into consideration to cultivate the herb plants, if the farmland proprietors would provide the plants. And, they had interest in planting, management and post harvest utilization and if a reference material would be provided as well. An approach to plant new crops might be possible to those who have more than four years of farming experience and possess relatively high level of cultivation techniques. In conclusion, the favorable crop cultivation strategy corresponding to the participants' abilities; and rental process were essential for the sustainable operation of allotment gardens and expanded number of participants. Moreover, there is a need to pay attention to the city dwellers who have a lot of farming experiences in allotment gardens to maintain agriculture and rural community. This is so, because they are interested in agriculture and rural community and most of them replied that they had intentions to move to rural areas in the future.

  • In ancient times, horse racing was done in ancient European countries in the form of wagon races or mountain races, and wagon racing was adopted as a regular event at the Greek Olympic Games. Thoroughbred horse has been bred since 17th century by intensive selective breeding for its speed, stamina, and racing ability. Then, in the 18th century, horse racing using the Thoroughbred species began to gain popularity among nobles. Since then, horse racing has developed into various forms in various countries and have developed into flat racing, steeplechasing, and harness racing. Thoroughbred racehorse has excellent racing abilities because of powerful selection breeding strategy for 300 years. It is necessary to maintain and maximize horses' ability to race, because horse industries produce enormous economic benefits through breeding, training, and horse racing. Next-generation sequencing (NGS) methods which process large amounts of genomic data have been developed recently. Based on the remarkable development of these genomic analytical techniques, it is now possible to easily carry out animal breeding strategies with superior traits. In order to select breeding racehorse with superior racing traits, the latest genomic analysis techniques have to be introduced. In this paper, we will review the current efforts to improve race performance for racehorses and to examine the research trends of genomic analysis. Finally, we suggest to utilize genomic analysis in Thoroughbred racehorse and Jeju horse, and propose a strategy for selective breeding for Jeju horse, which contributes job creation of Korea.
