This study identifies factors of Hanbok-trippers - a term for people who dress in Hanbok(Korean traditional costume) while going on a trip - who converge on Gyeongbokgung Palace by determining the characteristics of class, places to visit and preferred places. This study interprets the voluntary hobby activities of Hanbok-trippers from a viewpoint of a landscape prosumer and the meaning of the urban landscape. As a result of in-depth interviews, on-site survey, and observation surveys focused on Hanbok-trippers, there were various levels of participants. They are classified into three groups - leading group, entry group, temporary-experience group - according to their cognitions, types of Hanbok use, activities, etc. The leading group and entry group are a voluntary hobbyist class due to the ongoing tendencies of their participation. There are differences in the purpose and factors of visiting Gyeongbokgung Palace as a place for a Hanbok-trip. The leading group visited Gyeongbokgung Palace for cultural activities, regular get-together, public relations, and as a gathering place to go neighboring destinations. In this case, the main factors of the visit are the traditional landscape, convenient transportation, chances for traditional culture exhibitions and events in Gyeongbokgung Palace and its neighborhood. The entry group visits Gyeongbokgung Palace because of its traditional landscape and cultural activities nearby. The traditional landscape and many Hanbok-trippers are main factors of visiting Gyeongbokgung Palace for the Temporary-experience group. This study found that Gyeongbokgung Palace has a new sense of place of 'Introductory course of Hanbok-trip', 'Hanbok Playground' because temporary-experience group visits there to experience a Hanbok-trip for the first time. Hanbok-trippers consume places and landscape in actual places offline, producing a new landscape at the same time, and has the characteristics of a 'landscape prosumer' by producing landscape images online through their own personal or social media. Their colorful and voluntary movements contribute to the dynamism of the urban landscape and can become a new cultural asset for the city. The voluntary hobbyist class can be considered a new type of participants in bottom-up planning such as urban regeneration and place marketing. This study has significance in that it conceptualized the 'landscape prosumer' through the voluntary hobbyist class of Hanbok-trippers with the concept of the 'prosumer' that has been studied only in the consumer studies and marketing fields, and has identified the significance of the urban landscape.

This study examined how the households used and combined financing sources to pay for college education. It compared the probability of using each source (current incomes, saving, education loans and grants) by households' socio-economic characteristics and analyzed which factors influence the decision to use each source and the amounts from each source for financing college education. Data for this study were from a questionnaire completed by 4-year college students (n=623) and were analyzed by t-tests, ANOVA and Heckman's two-step estimation models. The findings of this study were as follows: First, the most frequent source for college education was parents' savings and the second one was parents' incomes. Also, the most frequent combination of sources was saving and current incomes and the second was combination of three sources, saving, incomes and education loans. Second, the probability of using incomes was higher for younger students than for older students. The number of siblings showed significant differences among income, savings and education loans. Those who had higher incomes were more likely to use current incomes, saving, but less likely to borrow for financing college education. Middle-class income groups were more likely to borrow for education. Third, household incomes and asset holdings had generally positive impacts on the probability of using incomes and savings for college education, while total debt burden decreased both the probability and amounts of income and saving sources. The college costs had significantly positive effects on both the probability and the amounts of all of financing sources. Total grants received significantly decreased the amounts from incomes, savings and borrowing sources.

Recently, there shows a trend in Korea that the rate of the population entering into aging is the most rapidly increasing among the OECD countries. Consequently, This study, therefore, aims at analyzing the forms of portfolio establishment by group, the factors affecting the old age preparation, and the presence of middle-aged households' preparation for the old ages in order to forestall social problems like the poverty ration of elderly that have been caused by the rapidly aging society. The result shows that the portfolio for the old age preparation can be expanded if a combination product of finance and real estate is developed as a means of old age preparation. Upon the results of the study above, it can be seen that the old age preparations differ according to not only the demographic elements, but also the extent to how much resources one holds. Especially, the various factors affecting the holding resources vary householder by household depending on whether they prepare for the old ages or not.

The purpose of this paper is to estimate technical efficiency, scale efficiency, and environmental efficiency by income level of Korean farms, and analyze the factors to decide three efficiencies. Depending on the non-parametric methods, we estimate technical using inputs and outputs of total farms without assuming of goods or behavior of optimization. The average technical efficiency of total firms under constant return to scale and strong disposability is 0.437. The technical inefficiency was caused by 47.7% in pure technical inefficiency, 11.3% in scale failure, and 3.2% in environmental inefficiency. The number of firms under increasing return to scale occupied almost 70% and 27% of total firms respectively. Higher are income class, middle debt & long debt per asset, and N effluents per cultural land, higher technical efficiency. The increases of BOD discharges per cultural land and machines per cultural land deteriorate environmental efficiency.

As Chinese political and economical status gets higher, a lot of multinational firms have tried to find some chances from the Chinese market successfully. Though geographically Korea is located closely to China, a lot of firms entering into Chinese market have turned out failed. Thus, this study researched Korean manufacturing firms in China, surveyed their localization degree of distribution, and tried to find out factors which influence these localization from a far-reaching literature. As a result of analyzing 146 questionnaires, the length of channel, among Chinese environmental factors, has a positive influence on the distribution localization degree. In addition, the factor of distribution relation assets has a positive effect on the distribution localization degree. Considering this study, the Chinese market, especially distribution field, has recently grown up to the world-class level. Therefore a firm intending to enter into China needs to be careful not to underestimate China.

During the past decade, it seems apparent that Bitcoin has been the best performing asset class. Even without a centralized authority that takes control over, Bitcoin, which started off with basically no value at all, reached around 65000 dollars in 2021, showing a movement that will definitely go down in history. Thus, even those who were skeptical of Bitcoin's intangible nature are stacking bitcoin as a huge part of their portfolios. Bitcoin's exponential growth in value also caught the attention of traditional banking and investment firms. Along with the spotlight Bitcoin is getting from the investment world, research using macro-economic variables and investor sentiment to explain Bitcoin's price movement has shown progress. However, previous studies do not make use of On-Chain Data, which are data processed using transaction data in Bitcoin's blockchain network. Therefore, in this paper, we will be utilizing LSTM, a method widely used for time-series data prediction, with On-Chain Data to predict the price of Bitcoin.

The research background of this paper is because the u-convergence information system applying flow theory lacks the measurement of tourist satisfaction. The purpose and research method of this study are as follows. The first is the suggestion of flow relation information display format algorithm. Second, by combining this algorithm and flow theory, a pattern algorithm was created according to the content information quality and the personality type of tourists. The expected effect of this study is to derive the success factors of the u-convergence information system by generating a pattern algorithm according to the flow relationship information display format and the tourist's personality type. The limitations of this paper are limited to one area, and objectivity is poor due to the lack of data and small area. In the future, it is necessary to evaluate the effectiveness through analysis after applying the method presented to other tourist destinations. Future tasks will need to be supplemented with data from expert groups and objectivity in various regions.

The records system is believed to have started in Italy in the 14th century in line with trade developments in Europe. In 1491, Luca Pacioli, a mathematician, and an Italian Franciscan monk wrote the first book that described double-entry accounting processes. In many countries, including Korea, the government accounting standards used single-entry bookkeeping rather than double-entry bookkeeping that can be aggregated by account subject. The cash-based and single-entry bookkeeping used by the government in the past had limitations in providing clear information on financial status and establishing a performance-oriented financial management system. Accordingly, the National Accounting Act (promulgated in October 2007) stipulated the introduction of double-entry bookkeeping and accrual accounting systems in the government sector from January 1, 2009. Furthermore, the Korean government has also introduced International Financial Reporting Standards (IFRS), and the System of National Accounts (SNA). Since 2014, Korea owned five national accounts. In Korea, valuation began with the 1968 National Wealth Statistics Survey. The academic origins of the valuation of national wealth statistics which had been investigated by due diligence every 10 years since 1968 are based on the 'Engineering Valuation' of professor Marston in the Department of Industrial Engineering at Iowa State University in the 1930s. This field has spread to economics, etc. In economics, it became the basis of capital stock estimation for positive economics such as econometrics. The valuation by the National Wealth Statistics Survey contributed greatly to converting the book value of accounting data into vintage data. And in 2000 National Statistical Office collected actual disposal data for the 1-digit asset class and obtained the ASL(average service life) by Iowa curve. Then, with the data on fixed capital formation centered on the National B/S Team of the Bank of Korea, the national wealth statistics were prepared by the Permanent Inventory Method(PIM). The asset classification was also classified into 59 types, including 2 types of residential buildings, 4 types of non-residential buildings, 14 types of structures, 9 types of transportation equipment, 28 types of machinery, and 2 types of intangible fixed assets. Tables of useful lives of tangible fixed assets published by the Korea Appraisal Board in 1999 and 2013 were made by the Iowa curve method. In Korea, the Iowa curve method has been adopted as a method of ASL estimation. There are three types of the Iowa curve method. The retirement rate method of the three types is the best because it is based on the collection and compilation of the data of all properties in service during a period of recent years, both properties retired and that are still in service. We hope the retirement rate method instead of the individual unit method is used in the estimation of ASL. Recently Korean government's accounting system has been developed. When revenue expenditure and capital expenditure were mixed in the past single-entry bookkeeping we would like to suggest that BOK and National Statistical Office have accumulated knowledge of a rational difference between revenue expenditure and capital expenditure. In particular, it is important when it is estimated capital stock by PIM. Korea also needs an empirical study on economic depreciation like Hulten & Wykoff Catalog A of the US BEA.

This study aims to analyze the status of the Gaetaesa Temple Site in Nonsan and the value of national cultural heritage associated with it, to work towards gaining the acceptance criteria to become state-designated cultural property and to propose a plan for comprehensive maintenance, a plan for the promotion of the project and a plan for the management and operation. The Gaetaesa Temple Site in Nonsan has unprecedented advancements, and the condition of the remains are relatively good. It would be necessary to conduct digging/excavation surveys continuously in the future and ensure the dignity of the Gaetaesa Temple Site in Nonsan as a cultural asset. In addition, the Gaetaesa Temple Site has excellent historical and cultural values as treasure-class cultural heritage. Most temples had treasures taken out of them, so it is necessary to designate this site as a state-designated cultural property instead of a municipality-designated cultural heritage site, and to manage it systematically. Accordingly, this study investigated the history and historical facts about the Gaetaesa Temple Site in Nonsan through the analysis of literature, including old documents, old maps, related academic papers and books, and referred to the results of digging/excavation surveys, conducted up to six times since the first excavation survey conducted in 1986, in order to understand the status of the remains, ruins and the building sites excavated at the Gaetaesa Temple Site in Nonsan. In addition, this study analyzed the values of the Gaetaesa Temple Site in Nonsan, dividing them into the remains, relics and ruins, and set up the scope of the Gaetaesa Temple Site in Nonsan, the cultural property area (designated and protected areas) and the acceptance criteria for the construction work in the historical and cultural environment preservation area. This study proposed a plan for the comprehensive maintenance of the Gaetaesa Temple Site in Nonsan, a plan for the promotion of the project and a plan for the management and operation. It is necessary to carry out ongoing excavation investigations and to reflect the opinions of the residents for the purchase of land, to supplement the comprehensive maintenance plan, business promotion and management plans, and step-by-step business plans should be established in detail.
