  • The expansion of internet and the development of communication technology have brought about an explosive increasement of data. Further progress has led to the increasing demand for efficient and effective data analysis tools. According to this demand, data mining techniques have been developed to find out knowledge from a huge amounts of raw data. This paper suggests a generalization based classification method which explores rules from real world data appearing repeatedly. Also, it analyzed the relation between weather data and forest fire, and efficiently predicted through it as a prediction model by applying the suggested generalization based classification method to forest fire data. Additionally, the proposed method can be utilized variously in the important field of real life like the analysis and prediction on natural disaster occurring repeatedly, the prediction of energy demand and so forth.

  • The main objective of this research was to understand the characteristics of printed geometric patterns through the statistical & qualitative analysis of fashion appeared in contemporary female collections 2011 S/S to 2013 A/W. Data collection of 294 was done through review of 'pr$\hat{e}$t-$\grave{a}$-porter Collections' of three major fashion cities; Paris, Milan and NY. Statistical analysis of frequency was conducted. Also qualitative interpretation of natural print design' characteristics were completed. The main findings were as followed; 1,636 of the total 15,852 designs were printed patterns in 12 Collections and the occurrence rate of printed geometric patterns in three collections were 8.6% in Milan, 9.2% in Paris and 12.9% in N.Y. Most geometric patterns were the types of compact or medium density in a front patterns with a variety of sizes and mainly applied to the one piece dress or two piece clothing item combination styles. Formative Characteristics of printed geometric patterns were classified into four types. First, a variety of thicknesses and shapes, such as a line or a rectangle shape to take advantage of the types of the typical geometric pattern. Second types were using the motifs which inspired by geometric shapes such as point, circle star and other special geometric shapes and arranging them regularly with various sizes and density. The third was repeated particular motifs which based on complex and sophisticated mathematical formulas. Fourth were the specific diagram types of bold and free shapes or dividing the flat and arranging them without rules, or the combination type of various geometric motifs.

  • In this study, the transport of pollutants was analyzed using the K-River and K-DRUM coupling model for water pollution accidents that occurred in the Nakdong River water system. In Korea, the necessity of a distribution model that accommodates the water circulation process and the importance of nonpoint pollution sources were emphasized in water quality management after the introduction of the total amount of water pollution. Therefore, in order to reflect the runoff characteristics of nonpoint sources, the K-DRUM distribution model, which can analyze pollution in the basin, was used. And the reproducibility of the model was improved by applying the operating rules of dams operating in the Nakdong River system. In addition, in order to analyze the movement of pollutants in the river, only the advection part of the advection-dispersion equation was applied to the 1D hydraulic model K-River to perform pollutant tracking. As a result of water pollution analysis, the peak concentration of the pollutant was underestimated, but the arrival time and the trend of the overall pollutant concentration were well reproduced.

  • Purpose - The UNCITRAL Model Law on Electronic Transferable Records (Model Law) is based on the principles of non-discrimination against the use of electronic means, functional equivalence, and technology neutrality underpinning all UNCITRAL texts on electronic commerce. Investigating the disagreements between the Model Law and the Koran Commercial Act (KC Act), including the B/L Regulation, and suggesting the revision of the KC Act including the B/L Regulation, could be a valuable study. The purpose of this paper is to contribute to the harmonization of Korean legislation regarding electronic bill of lading in compliance with the Model Law. Design/methodology - The Model Law is flexible to accommodate the use of all technologies and models, such as registries, tokens, and distributed ledgers: that is, blockchain. In 2007, the KC Act was revised to regulate electronic bills of lading to promote the widespread legal use of electronic bills of lading. In addition, The Regulation on Implementation of the Provisions of the Commercial Act Regarding Electronic Bills of Lading (the B/L Regulation) was enacted to regulate the detailed procedures in using electronic bills of lading in 2008. This paper employs a legal analysis by which this paper does find differences between two rules in light of technology neutrality and global standard of electronic bills of lading model. Findings - The main findings are as follows: i) the Korean registry agency has characteristics of a closed system. ii) The KC Act has no provision regarding control. iii) The KC Act discriminates other electronic bills of lading on the ground that it was issued or used abroad. Moreover, this study does comprehensive analysis of Korean Acts in comparison with the Model Law and, in particular, this study analyzes the differences between the KC Act and the Model Law by comparing article by article in view of the harmonization of the two rules. Originality/value - The subject of previous several studies was draft provisions on Electronic Transferable Records before completion of the Model Law; thus, these studies did not take into consideration the character of the Model Law as the Model Law was chosen at the final stage of legislation. This study is aimed at the final version of the Model Law. So, this study is meaningful by finding the suggestion and directions for the Korean government to revise the KC Act and the B/L Regulation in line with the Model Law.

  • The purpose of this study was to identify housing attributes that make residents feel 'at home' in ALFs in Southwest Virginia. For this purpose, residents' needs, experiences, and opinions of the physical environment, the social environment and the organizational environments such as policies and programs of ALFs were identified. As a multi-case study, five ALFs in Southwest Virginia were studied using constant comparative methods of data analysis. In addition to face-to-face interviews with 25 residents and 5 administrators of five ALFs, observations were conducted with personal journal. Each facility was designed to be a single-family house or multi-family dwelling in outside appearance. Most of the respondents were satisfied with their current dwelling as a 'home' in terms of homelike attributes such as 'autonomy/ privacy', personalization,' safety and security,' services and care,' independence,' social interaction/friendship,' family support,' and 'rules and regulations.' In spite of high satisfaction with the facility, however, many people did not think of their current dwelling as a real 'home'. As the biggest difference between living in their own homes and living in the ALF, people feinted out a lack of independence and social interaction. Residents of ALFs may have reordered their priorities in their current life situation so that safety, security, and caie were more important to them than fooling "at home."

  • In internet being a repository of massive information, we easily may not find our desired information, this issue also exists in e-commerce which gets rapid growth. In most of e-commerce sites, the methods furnishing information have been made use of statistical analysis or simple process by category-oriented, but these can't represent diverse correlation among products information and also hardly reflect users' purchasing patterns precisely. In this thesis, we propose more efficient web mining ways for discovering interesting information using effective clustering in e-commerce, which get achieved more suitable relationship among products information using both sequential patterns and association rules in category-independent, and experiments show the efficiency of our proposed methods. And we propose search using effective clustering rapidly.

  • Web logs are the information recorded by a web server when users access the web sites, and due to a speedy rising of internet usage, the worth of their practical use has become increasingly important. Analyzing such logs can use to determine the patterns representing users' navigational behavior in a Web site and restructure a Web site to create a more effective organizational presence. For these applications, the generally used key methods in many studies are association rules and sequential patterns based by Apriori algorithms, which are widely used to extract correlation among patterns. But Apriori inhere inefficiency in computing cost when applied to large databases. In this paper, we develop a new algorithm for mining interesting patterns which is faster than Apriori algorithm and recommendation agents which could provide a system manager with valuable information that are accessed sequentially by many users.

  • Urban forests have various environmental benefits, contributing to the quality of urban life. However, these values have been underestimated or never been reflected in the urban development planning in Korea. As a result, a number of forests in urban areas were either partly or wholly destroyed without their public's values being assessed explicitly. The objective of this paper is to estimate the economic benefits attached to Mt. Kwanggyo in the Capital Region using contingent valuation method, aiming to provide policy-makers with useful information to make an informed public decision in urban development planning. The survey was carefully designed and implemented to meet a number of recommendation rules suggested in the literature. The overall results show that the respondents well accepted the contingent market and would be willing to pay a significant amount for the proposed program of conserving the mountain. Total economic benefits for the population amounted to approximately 3.8 billion Korean won per year. This quantitative information can be used in cost-benefit analysis of urban development plans.

  • The 21st century is witnessing the explosive increase in the usage of internet and international electronic transactions. Due to the unique characteristics of the electronic information, substantial part of such transaction can and do take the form of cross-border transactions. However, there have not been settled appropriate set of rules applicable to the international electronic transactions. Currently, in respect to e-L/C transactions in international trade, there are laws such as Electronic Transaction Basic Act in our country, E-Trade Promotion Act, E-Signature Law, Act on Promotion of Information and Communication Network Utilization and Information Protection and Marine Charter 5 in the Commercial Law. Nevertheless, a complete legislation, that is a uniform rule for e L/C which could support e L/C transactions fully hasn't been established yet. Accordingly, those laws concerned need to improve to regulate e-L/C transactions. The purpose of this paper is to look into the national status for law readjustment to prepare for a new electronic environment and to use appropriately the e-L/C issued by electronic means, and to conduct a comparative analysis on the related regulations to introduce a pertinent laws and propose related regulations to contribute to the making of effective laws to regulate e-L/C.

  • So far, research into multinational bank' overseas expansion has focused on foreign direct investment in the financial services industry. However, this study focused its existing theories on multinational banks on decision-making related to the type of overseas advancement of local financial institutions. For research, four environmental factors were considered: the scale of foreign direct investment, the scope of financial services that can be provided according to the rules of the host country, the corporate tax rate of the host country, and the level of development of the host country's banking industry. Through Kotra, data on the total amount of claims from 2010 to 2014 and the regulatory status for the country's financial industries were obtained. Hypothesis are built around theories and survey factors and has been demonstrated through regression analysis. Results show that Korean financial institutions tend to expand as legally independent subsidiaries where the corporate tax rate of the host country is relatively low. Contrary to the previous studies based on the U.S. banking corporates, results show that Korean banks tend to expand in forms of branches to the host countries with high level of banking system development.
