The purpose of data fusion is collecting maximized information from combining the data attained from more than two same or different kind sensor systems. Data fusion of same kind sensor systems like optical imagery has been on focus, but recently, LIDAR emerged as a new technology for capturing rapidally data on physical surfaces and the high accuray results derived from the LIDAR data. Considering the nature of aerial imagery and LIDAR data, it is clear that the two systems provide complementary information. Data fusion is consisted of two steps, alignment and matching. However, the complementary information can only be fully utilized after sucessful alignment of the aerial imagery and lidar data. In this research, deal with centroid of building extracted from lidar data as control information for estimating exterior orientation parameters of aerial imagery relative to the LIDAR reference frame.

As the complexity of business environment increases rapidly the use advanced information technology start to affect not only the business processes of individual companies but also the fundamental nature of business and industrial ecosystem. The changes observed at the level of business and industrial ecosystem encompasses a broad range of transformation. This unit of analysis is not sufficiently dealt with by existing information system research. This research attempted to analyze the changes in business ecosystem caused by digital transformation using Social Network Analysis. We studied structural change of the Korea film industry ecosystem chronologically divided by critical events. The film industry is chosen because it is an industry very sensitive to the changes in technology and has gone through massive transformation during the last three decade by way of using modern information technology.

The laminating technique for developing flexible liquid crystal display was demonstrated by using a thin UV curable polymer film and a plastic substrate with patterned polymer wall structure. We adopted the rigid wall structure to provide a solid mechanical support for the stable molecular alignment of liquid crystals (LCs) in the device. The cover film was prepared to have an ability of aligning LC molecules by patterning a micro-groove structure using the soft-lithographic process. These two substrates can be assembled tightly by the laminating and one-step UV irradiation process because of the adhesive nature of the used UV curable polymers. Proposed method can be used to fabricate the flexible LC display with simplicity and also be applicable for a cost-effective roll-to-roll process.

The terms electronic trade, electronic trading and electronic commerce are often used interchangeably, and refer to trading transactions conducted using electronic media. Electronic trade is business-to-business transactions in an industrial context, while electronic commerce refers to retailing and the consumer sector as well as mass marketing. The Electronic trade process is defined as a flow of information (documents) exchanged between enterprises and trade-related firms (shipping companies, foreign exchange banks, forwarders, etc.) in the course of implementing a series of export and import procedures. Electronic trading systems exploit information technology to improve the efficiency of communications and/or to alter the nature of inter-organizational transactions. Many studies exist about the adoption of inter-organizational systems (IOS) and electronic data interchange (EDI), but few focus on electronic trade. The literature on exporting companies's electronic trade adoption and implementation, although extensive, consists mainly of exploratory studies focusing on technological characteristics such as barriers, benefits and usage. The purpose of this study is to broaden this perspective by investigating the environmental, organizational and technological drivers of business-to-business e-commerce adoption.

ISO 15489에 따르면, 기록이란 "조직이나 개인이 법적 의무를 수행하거나 업무를 처리하는 과정에서 증거나 정보로서 생산, 접수, 유지하는 정보"(ISO 15489-1:2001, 3.15) 이다. 본고에서는 이러한 기록의 정의의 의미가 무엇인지, 기록의 법적 증거로서의 특성을 중심으로 살펴보기로 한다. 이를 위해 현재 상법과 형사소송법에서 언급한 기록의 용례를 살펴봄으로서 기록의 속성을 검토해보기로 한다.

본고는 1980년대와 90년대를 거쳐 미국과 캐나다에서 활발히 이루어졌던 기록정보 서비스에 대한 논쟁을 살펴보고, 이를 통해 기록정보 서비스의 본질과 의미를 고찰하고자 한다. 당시 학자들은 논쟁을 통해 기록관리가 기록 중심에서 이용자 중심으로 바뀌어야 하는가에 대해 다양한 의견을 피력했고, 기록관리의 의미와 원칙에 대해 재확인했다. 이러한 이용자 중심의 기록정보 서비스 논쟁을 바탕으로 본고의 후반부에서는 한국의 정보공개 청구 중심으로 이루어지는 기록정보 서비스를 살펴보고 문제를 제기하였다.

The temporal structure of events on the discourse level has long been of great interest in both theoretical and computational linguistics. In this paper, we offer a unified approach to the temporal relationships related to a hierarchical discourse structure. We apply the method of pronoun resolution to the interpretation of tense. It is based on an analysis within the framework of the controlled information packaging theory. A unique aspect of our account is that temporal interpretation across discourse segments in global discourse is subject to the same principles as the interpretation of global anaphora, and that there is thus no need to postulate independent principles to account for the discourse behaviour of tense. In this way, we can neatly explain the general view that tense parallels the anaphoric nature of pronouns.

Since its first appearance in the late 1970s and early 1980s, executive information system (EIS) has been reported to improve executives' productivity in line with the rapid growth of the EIS market. In this paper, we aim to provide both researchers and practitioners with a comprehensive bibliography on EIS. this bibliography consists of papers which were extracted from (1) INSPECT commercial database service, (2) previous surveys in books and journals, and (3) major conference proceedings. A total of 227 papers, published between 1983 and 1992, were identified and categorized by topic, and journal or conference. The major findings indicate that EIS has been widely used in both profit oriented organizations and non-profit oriented organizations and that the nature of system has been the most active topic among the researchers and practitioners. However, the survey suggests that further research should be focused on development and implementation methodologies of EIS, especially requirement analysis and EIS planning.

Hangul is unique compared to other Asian languages because of its simple letter forms that combine to create syllabic shapes. There are 24 basic letters that can be combined to form 27 additional complex letters. This produces 51 graphemes. Hangul optical character recognition has been a research topic for some time; however, handwritten Hangul recognition continues to be challenging owing to the various writing styles, slants, and cursive-like nature of the handwriting. In this study, a dataset containing thousands of samples of 51 Hangul graphemes was gathered from 110 freshmen university students to create a robust dataset with high variance for training an artificial neural network. The collected dataset included 2200 samples for each consonant grapheme and 1100 samples for each vowel grapheme. The dataset was normalized to the MNIST digits dataset, trained in three neural networks, and the obtained results were compared.

Information Systems(IS) departments face many challenges in today's rapidly changing environment. One approach to understanding the challenges by IS departments is to survey IS managers in order to elicit their key issues. The study compares and contrasts the major findings of key information systems management issues in Korea and United States. It examines the key concerns of IS managers on these areas focusing on identifying and explaining regional similarities and differences. IS managers in Korea and United States show a reasonable level of agreement on the most critical issues they face. In some of the issues the differences are found and possible reasons for these differences are discussed. The study concludes by suggesting an evolution model that can explain the changing nature of the IS issues across time and nations.
