With increasing interest in key areas of the 4th industrial revolution such as artificial intelligence, deep learning and big data, scientific approaches have developed in order to overcome the limitations of traditional decision-making methodologies. These scientific techniques are mainly used to predict the direction of financial products. In this study, the factors of apartment prices, which are of high social interest, were analyzed through SOM. For this analysis, we extracted the real prices of the apartments and selected a total of 16 input variables that would affect these prices. The data period was set from 1986 to 2021. As a result of examining the characteristics of the variables during the rising and faltering periods of the apartment prices, it was found that the statistical tendencies of the input variables of the rising and the faltering periods were clearly distinguishable. I hope this study will help us analyze the status of the real estate market and study future predictions through image learning.

This study examines the housing-related characteristics of unmarried youth using occupational history data from the 10th-14th (2016-2020) youth panel (YP2007) of the Korea Employment Information Service, and the characteristics of housing and employment. Their effect on marriage intention was empirically analyzed. The results of the analysis show that highly educated people, high-wage workers, household heads or economically independent young people, and young people in good financial conditions have a high willingness to marry. Their economic conditions are very important factors. Among the young employed who have become economically independent from their parents, full-time permanent workers, workers at large corporations, and highly waged youth showed a strong desire to get married. On the contrary, young people who are insecure temporary/daily workers, workers at small firms, and low-wage workers show a low willingness to marry. In conclusion, the results imply that young people who are in a vulnerable state in the labor market are giving up or delaying their marriage. Therefore, it is necessary to enhance policies to provide better employment opportunities for youth and, simultaneously, revamp the policy measures to enhance housing conditions.

Due to various reasons (normally financial constraints in developing countries), it becomes common to change of the business model from state-run projects to Private Investment Projects (Public Private Partnership) in the global railway businesses. However, due to the nature of railroads compared with other types of infrastructure such as roads and others, railway business require considerable construction cost and O&M cost through the business development, construction, and operation and management stages. Therefore, private investment railway projects, especially in developing countries, can be problematic in terms of the potential for uncertainty when return on investment cannot be guaranteed. In order to strengthen the competitiveness of domestic companies when entering overseas railroad PPP projects, this study proposes PPP-related risks and their countermeasures by reviewing global railroad trends and identifying Korea's weakness in managing international railroad projects.

This study applied the method of Diebold and Yilmaz (2012, 2014, 2016) to analyze the connectedness between the Freight Index (BDI, BDTI, BCTI), energy price(oil, natural gas, coal), and grain price(soybean, corn, wheat) from July 19, 2007 to March 31, 2022. The main analysis results of this paper are as follows. First, according to the network analysis results, the total connectedness was measured to be 20.43% for the entire analysis period, indicating that there was a low correlation between the freight index and the commodity price. In addition, looking at the directional results, the variable with the greatest effects was corn, and conversely, the variable with the lowest effects BDI. When classified by events, BCTI was found to play a major role only during the COVID-19 period. Second, according to the results of the rolling-sample analysis, the total connectedness be found to be highly correlated with changes in economic conditions such as the financial crisis, trade war, and COVID-19 when specific events occurred.

In China, with the rise of third-party payments such as WeChat Pay and Alipay, the traditional business of banks has been greatly affected. Banks can encourage and expand QR code payments to merchants. Therefore, it is meaningful to analyze and study the QR code work of banks. The purpose of this study is to analyze the effect of the execution of the zero-rate of the comprehensive payment QR code combined with the payment cycle and Funds Transfer Pricing (FTP) on commercial banks in China. Based on the manually collected customer data of Chinese commercial banks, this paper conducts a case analysis combined with the calculation method of financial indicators. As a result of the study, it was found that commercial banks need to continue to implement the policy as the advantages of introducing the integrated QR code fee rate 0 policy are greater than the disadvantages. This paper provides feasible suggestions on how to quickly occupy the offline payment market for commercial banks, which has guiding significance for commercial banks' marketing decisions. Presently, there are few studies on the zero-rate subsidy policy implemented by Chinese commercial banks.

The purpose of this paper is to examine the relation between executive excesss compensation and credit rating. According to the prior research which show the negative effects of excess compensation on a firm's future performance, this paper expects the negative effect of excess compensation on credit rating. Using a sample of Korean listed non-financial firms from 2014 to 2019, I perform the multivariate regressions analysis of excess compensation on credit rating. I find that excess compensation is negatively related to credit rating when executive compensation exceed expected executive compensation. Moreover, I find that the result is constant when a fim belongs to small-medium business. These results show that credit rating is affected by executive excess compensation and the relation could be different by the type of firm's size. Therefore, this study contributes to the literature by suggesting the possibility that capital market is aware of negative effect of executive excess compensation.

Purpose - This study aimed to clarify the effects of tax investigation probability on accounting transparency in KOSDAQ firms by using financial statement. In particular, it was analyzed whether the characteristics of a firm's listed market have a discriminatory effect on the relationship between the tax investigation selection rate (or detection rate) and earnings management. Design/methodology/approach - This paper examines analyzed the effect of tax investigation of the National Tax Service on the earnings management. The sample includes 9,603 firms listed on KOSPI and KOSDAQ from 2011 to 2018, all of which are manufacturing firms. This study conducted correlation and multiple regression analyses to verify the relationship between tax investigation probability and earnings management. The possibility of a tax investigation is the selection rate and the detection rate, and the profit adjustment was estimated at discretionary amount. Findings - As a result of empirical analysis, both firms listed on KOSPI and KOSDAQ markets showed that the higher the tax investigation rates, the more significant the possibility of reducing the earnings management of discretionary accruals. Additionally it was found that in KOSDAQ markets firms, the tax investigation detection rates had a signigicant nagative effect on discretionary accruals. Research implications or Originality - It can be interpreted that firms with a high rates of receiving a tax investigation decrease earnings management consideration of expenses such as additional tax amount due to the tax audit or a decline in corporate image.

As human life and welfare become more valued in the Fourth Industrial Revolution era, the role and mission of human ecology are expanding. Therefore, a career exploration and education program for high school students covering all the academic fields of human ecology may be necessary. To investigate what would be needed to develop such a program, a focus group interview (FGI) targeting experts within the same field and a survey targeting high school students were conducted. As a result of the FGI, a total of 3 categories and 7 subcategories were identified. The three categories included "human ecology and high school education," "human ecology and career choices," and "education program development and management in human ecology." The results of the high schoolers' survey showed that they had a moderate level of awareness about careers related to human ecology majors, but their interests and known information about human ecology programs in universities were low. Within the sub-content of each major, the contents with the highest educational needs were fashion product management, nutrition by disease, housing market analysis, personal financial management, and children's rights and welfare. If a career exploration and education program is implemented in the future, the most preferred type is a mentoring program by professors, students, and graduates in the field of human ecology. In conclusion, it is necessary to develop and implement an integrative education program about human ecology majors based on the educational needs of high school students.

Purpose: This study examines the factors that the Millennials and Gen Z prefers to invest in assets. We look at the asset structure they want now and in the future and the idea of designing the future. This can be expected that the center of Korea's asset market will change to the structure they want in the future. Research design, data and methodology: The spatial extent of the study is all over Korea including Seoul, the metropolitan area, and local cities. The survey was conducted for about 16 days from May 7 to May 22, 2023. The survey was conducted by the surveyor visiting the subject in person, distributing the questionnaire, explaining it, and filling it out in person. For the analysis, descriptive statistics and logistic regression analysis were conducted using the SPSS 25.0 statistical package. Results: It was confirmed that the preferred assets of the Millennials and Gen Z were different by period. There was also a difference in the influencing factors between Millennial Generation and Generation Z in asset preference. Conclusions: The Millennials and Gen Z's preferred assets were different by period. The reason is interpreted as the current process of collecting assets during the asset formation period. In the future, they intend to purchase real estate assets by using financial assets as a lump sum of money. We learned the characteristics of the entire Millennials and Gen Z, in addition, the difference between income and assets is believed to have affected the difference in preference factors of Millennial Generation and Generation Z, respectively.

The market of building construction has been competitive in Hong Kong, perhaps as anywhere else in the world. The barrier to entry is low because there are relatively low requirements on the three factors of production - technology, manpower and finance. The prevailing building technology is traditional and labour-intensive. There is also not much need of capital because clients' periodic payments have been the main source of project finance. Further, capitalizing on trade sub-contracting, contractors have been able to keep their direct labour-force small and to transfer much of their business risk to the sub-contractors. Based on interviews to solicit the perception of a sample of building contractors on the particular issues of construction finance, we present the findings in this paper and discuss the various implications. We believe that the current practice of construction financing is both the cause and effect of the competition within, and the competitiveness of, the building construction sector in Hong Kong. We conclude that the building construction sector is "locked or stuck" in this "equilibrium" of traditional technology, reliance on clients' finance and exploitation of sub-contracting. In this "equilibrium" state, there is hardly any motivation for contractors to engage themselves in product or process innovation. Consequently, any talk of industry reform or innovation could only remain just that. We believe that this problem is not unique in Hong Kong. The building construction sector in many other developed and developing economies is posed with similar if not the same problems and constraints. We conclude that there has to be some "external forces" to bring this "equilibrium" state to a higher level "equilibrium" one where higher value-added building construction services are supplied and demanded. This is a state where building contractors possessing innovative technology, better financial and manpower resources could thrive to build better buildings with innovative building methods and processes.
