A. The principal geographical descriptions compiled by the government during Yi dynasty started from the Shinchan-Paldo-Chiriji(新撰八道地理志) which was compiled by the royal decree in the sixth year (1424) of King Sejong(世宗) and it ended in the Jungbo-Munhonbiko(增補文獻備考) which was published in the second year(1908) of Yunghyi(隆熙). The process of their compilations can be divided into four steps according to the compilatory work's contents of the principal geographical descriptions which were compiled through the Yi dynasty. We can say that the first step (1424-1454) of those works began at the date of the compilation of the Shinchan-Paldochiriji and it ended in the date of the compilation of the "Sejongsilok-Chiriji"(世宗實錄地理志), and during that period the Kyonsangdo-Chiriji(慶尙道地理志) was published. In the second step(1455-1531), were published the Paldochiriji,(八道地理志), Kyongsangdosokchanchiriji(慶尙道續撰地理志), DonggukYojisungnam(東國與地勝覽) and the third step (1532-1769) began at the date of the compilation of the Dongguk-Munhonbiko(東國文獻備考) and it ended in the date of the publication of the Jungbo-Munhonbiko(東國文獻備考), and in that period the Jongjung-Munhonbiko(訂增文獻備考) was published. The works of compilation of the Eubjis in the period of King Kojong(高宗) came within the category of the fourth step. B. Generally speaking, the state geographical descriptions were composed of the regional data of the country which were collected and arranged. In other words, firstly, the Eubjis were compiled in each county, secondly, the Dojis(道誌) were compiled based upon the collections of all the Kunjis(郡誌), lastly, the government collected all the Dojis and compiled them into the state geographical descriptions. The Eubjis in the early days of Yi dynasty were compiled as the data for the compilation of the nation-wide geographical descriptions, but the Eubjis in the age of King Kojong were compiled as the administrative data. C. The main contents of the Eubjis were composed of the descriptions on the geography, history, industry, naval and military affairs, traffics, communication, administration, economy and society, and of the matters on the prose and poetry, persons of loyalty, historic remains, social customs and schools. Consequently, the above-mentioned data will be contributed to the study on the structures of the geography, history, economy, administration, education, naval and military affairs and traffics as well as the study on the literature, social customs and bibliography. Especially, they will be important data for the arrangement of cultural assets of our country. Furthermore, because the traditional study of national literature was centered around the study on the central government ignoring the study on the regional matters, the study of the Eubjis will be worthy of being valued.

The purpose of this study is to find out the factors affecting the usage and performance of e-Trade in Chinese Small and Medium-sized Enterprises(SMEs). To achieve the purpose of the study, the research model and hypotheses, depicting the relationship among external factors, internal factors, relationship characteristics, e-Trade usage level, and performance were developed based on the existing literature on e-Trade. To test the significance of the research model and hypotheses, an empirical survey were conducted to the Chinese SMEs in Yangtze River Delta area, which are actively using the e-Trade in their trade processes. According to the result of the statistical analyses on the 85 effective questionnaires from the sample firms, support of the government related institutions(one of the external factors) and CEO's support(one of the internal factors) had significant relationship with e-Trade usage level, but no significant relationship was found between the relationship characteristics and e-Trade usage level. Like the results of the most of the existing literature, e-Trade usage level were formed to significantly affected the e-Trade performance. Finally, based on results of the empirical survey, several implications on the Chinese SME's e-Trade strategies and policy alternatives were proposed as a concluding remark.

Along with the development of communication technology, DTV is gradually evolving into media that provide diverse services and information. This study is related with remote controls that control DTV interfaces and assessed the usability of remote pointing device. To this end, pointing devices using three different interaction methods that have been attempted recently by the industry were selected to conduct empirical experiments. The usability assessment was conducted centering on the existing directional task on straight tracks presented in ISO 9241-Part 9 and the steering tunnel task on curved tracks proposed in this study. The measurement variables included movement time, accuracy, throughput, subjective satisfaction and user behaviors. Based on the results of the assessment, in the case of movements on straight tracks, the GyroPoint method showed better implementing time but lower accuracy compared to the Hall Mouse and OFN methods while in the case of assessment on curved tracks, all of the GyroPoint method, Hall Mouse and OFN methods showed excellent results on both implementing time and accuracy. Besides, differences in efficiency and subjective satisfaction were shown among individual pointing devices. Based on these results, it is considered that individual pointing methods have different advantageous and disadvantageous characteristics. In this study, the usability of remote control pointing methods was assessed and diagnosed reflecting environments where DTVs are used through assessments considering the aspect of straight tracks along with curved tracks. Among others, this study is considered to be meaningful in that it provides assessment criteria and basic data for the development of remote controls suitable for the evolving DTV environments.

Smart City's goal is to solve urban problems through smart city's component technology, thereby developing eco-friendly and sustainable economies and improving citizens' quality of life. Until now, smart cities have evolved into component technologies, but it is time to focus attention on the needs and participation of citizens in smart cities. In this paper, we present a big data procedure for solving smart city problems based on citizens' needs and participation. To this end, we examine the smart city project market by region and major industry. We also examine the development stages of the smart city market area by sector. Additionally it understands the definition and necessity of each sector for citizen participation, and proposes a method to solve the problem through big data in the seven-step big data problem solving process. The seven-step big data process for solving problems is a method of deriving tasks after analyzing structured and unstructured data in each sector of smart cities and deriving policy programs accordingly. To attract citizen participation in these procedures, the empathy stage of the design thinking methodology is used in the unstructured data collection process. Also, as a method of identifying citizens' needs to solve urban problems in smart cities, the problem definition stage of the design sinking methodology was incorporated into the unstructured data analysis process.

Standards boost technological innovation by promoting information sharing, compatibility, stability and quality. Identifying groups of companies that particularly benefit from these functions of standards in their technological innovation and commercialization helps to customize planning and implementation of standards-related policies for demand groups. For this purpose, this study engages in profiling of SMEs whose R&D objective is to respond to standards as well as those who need to implement standards system for technological commercialization. Then it suggests a prediction model that can distinguish such companies from others. To this end, decision tree analysis is conducted for profiling of characteristics of subject SMEs through data mining. Subject SMEs include (1) those that engage in R&D to respond to standards (Group1) or (2) those in need of product standard or technological certification policies for commercialization purposes (Group 2). Then the study proposes a prediction model that can distinguish Groups 1 and 2 from others based on several variables by adopting discriminant analysis. The practicality of discriminant formula is statistically verified. The study suggests that Group 1 companies are distinguished in variables such as time spent on R&D planning, KoreanStandardIndustryClassification (KSIC) category, number of employees and novelty of technologies. Profiling result of Group 2 companies suggests that they are differentiated in variables such as KSIC category, major clients of the companies, time spent on R&D and ability to test and verify their technologies. The prediction model proposed herein is designed based on the outcomes of profiling and discriminant analysis. Its purpose is to serve in the planning or implementation processes of standards-related policies through providing objective information on companies in need of relevant support and thereby to enhance overall success rate of standards-related projects.

Purpose - This study was conducted to evaluate service quality, perceived value, and satisfaction in the performing arts in order to establish a system of relationships that predicts repurchase intention, which increasingly needs to be studied as the domestic performing arts market grows. Research design, data, and methodology - Another purpose of this study is to identify 'work-related factors' and 'performing-arts-related factors' in the performing arts industry, and to observe the influence of the core SQ factors expected to influence audiences' purchase intentions through perceived value and customer satisfaction. The empirical study to test the hypothesis was based on a review of the literature and employed the survey method; data were collected from a total of 500 audience members. Results - The major results of the analysis are as follows. First, in terms of quality factors affecting perceived value, literary quality, level, professionalism, and musical quality were shown to have a significant influence as key factors from the performing arts perspective, while reliability, convenience, and related costs were indicated to exert a significant influence as additional factors related to work. Secondly, the quality factors with a significant influence on customer satisfaction were literary quality, professionalism, and musical quality, which were shown to have a significant influence from the performing arts perspective, while only reliability was indicated to exert a significant influence on work-related factors. Third, perceived value was shown to have a strong positive (+) influence on customer satisfaction, with both perceived value and customer satisfaction exerting a significant influence on the revisit intention. Finally, according to the results a difference analysis with demographic variables, viewing variables as moderating variables, differences according to gender were indicated in the influence of literary value and lel on perceived value, and in the influence of convenience and professionalism on customer satisfaction as well. Also, in terms of the influence of perceived value on customer satisfaction, males were found to be more influenced than females. Conclusions - Based on the above results, the suggested implications of the present study are as follows. First, through the consideration of not only the crucial work perspective in performing arts services, which has been inadequate in the past, but the additional performance-related level, the previously unevenly distributed viewpoints were expanded for application. Second, in verifying the relationship between expanded quality factors and the factors that determine consumer behavior while simultaneously considering key factors and additional related factors, work-related service quality factors were shown to exert a stronger influence on perceived value and customer satisfaction than performance-related factors. Third, for service factors related to performance, the reliability factor exerts an influence on perceived value and customer satisfaction, requiring that a performance planner secure and manage diverse channels to immediately support customer requests in providing performance theater services.

In this paper, we suggest a route plan sharing service for the navigation assistance service which is the second item of 16 items in maritime service portfolios (MSPs) for safety navigation based on interview process. Also, we developed scenarios for effectiveness evaluation of the proposed service, and conducted simulations using full mission ship handling simulator (FMSS) for effectiveness evaluation of proposed services based on the developed scenarios. Through the simulations, we analyzed proximity measures, controllability statistics and subjective evaluations to assess the usefulness of suggested service. If accomplishing the test for new services to apply real ships and vessel traffic (VTS) center, there has possibilities to occur various risks in terms of time/cost problems. Therefore, there is needs for the preliminary effectiveness evaluation processes necessarily when adopts and implements new services. Because we expected the service that is helpful for safety navigation, but the test results are not when conducted a simulation.

Based on the successful use of chatbot technology, this study examined what business values each company is creating. The chatbot service contributes to improving the productivity of the company by helping to answer or respond to the questions of employees inside the company or customers. And in the field of education, Instead of instructor, AI technology responds the questions and feedback of the students to reduce the work of the instructor. In the field of commerce, offline stores provide convenient and new purchasing experiences to customers by providing product purchasing services through artificial intelligence speakers and personalization service. Although chatbot service is creating business value in some business cases, it is still limited to the process of a specific company, and the spread rate is still slowing because the service scope, convenience, and usefulness are not greater than expected. Therefore, some chatbot development service providers is providing an integrated development platform to improve usability, Chatbots have the features and advantages of providing convenience instead of answering human questions. However, there is a disadvantage that the level of communication can be lowered by reducing various human subjective views and giving mainly objective answers. Through this study, we will discuss the characteristics, advantages and disadvantages of chatbot services by comparing them.

Although the use of CAD and CAM technologies has been broadly adopted by architecture-engineering- construction-facility management (AEC/FM) industry as the means of producing complex forms, there are still remained issues such as reducing cost, and enhancing quality and manufacturability. In this paper, to resolve given issues, we suggest a process of rationalization in digital architecture design and fabrication as an integrated approach. The rationalization, which is usually used as the term related with the skin panel of free-form architecture, is a process of re-designing a digital model to meet the requirements of manufacturing considering the gap with an original designs. Thus we classified this process and conducted a case study of fabricated models as an exploratory study. As the result, we found that each phase is connected with other phases with the circulation of information and rationalization process can be determined as the circulative process which re-designs digital model by minimally deviating from the original design based on the information deducted from analysis of inter-compatability of software and requirement of hardware.

Liechtenstein has $160km^2$ land and about 36,000 residents. Despite its small size of country, however, Hilti Corporation doesn't view its location as a liability in its business strategy. Hilti is a global leading provider of professional power tools in building, mining, civil engineering etc. Also, Hilti is a firm with a clear vision to become the leading industry partner for construction professionals and building installations through customer focus, high quality equipment, and tools and systems specially designed for specific jobs. This study considered Hilti as a good case, which verifies that born-conditions, endogenous factors according to Michael Porters diamond model does not decisive role more for international competitiveness of firms. Lessons from Hilti are that in order to obtain and sustain the global competitiveness of small and medium-sized firms in Korean manufacturing sector under high production cost, they have to do actively innovative. Also they can give to customers newer and higher customer-values than competitors in abroad give. The case summarizes that the strategy of Hilti for the global market success is comprised of several factors: Technological and organizational innovation, and a clear customer-value oriented business strategy and its implementation. Innovation and its integration into marketing for the customers value creation is central to Hilti's Success. The present case study is expected to provide insights and implication for many firms in Korea that are seeking to secure global presence and market success.
