It was 1976 when the preparation of consolidated financial sheet was first prescribed in this nation. Since then, the prescription has been revised several times. Revised in April 1992, enforcement regulations of the Securities Exchange Act provided that every listed corporation has its consolidated financial sheets and an auditor's opinion about them attached to its business report. In other words, the outside audit of consolidated financial sheets became inevitable. The Act of the Outside Audit of Corporation was revised in December 1993 to provide that all corporations must prepare consolidated financial sheets and receive the outside audit of the documents beginning their settlement of accounts in December 1994. In case of overseas corporations, consolidated financial sheets and the Equity Law have been applied since their settlement of accounts in December 1995. Now those sheets must be prepared by all local and overseas corporations that involve relations of governance or dependence. The preparation and public notification of consolidated financial sheets has been settled as a system. This nation has not yet introduced consolidated tax return using consolidated financial sheets. Such tax return system is already being used by most of the world's economic powers such as U.S., Europe and Japan. This study shows that reduction in corporation tax is the biggest reason for avoiding consolidated tax return system, even though the system can facilitate the settlement of consolidated accounting. Consolidated tax return, which is being implemented in about 20 countries including U.S., needs to be introduced by this nation where consolidated financial sheets are publicly notified.

With the development of deep learning techniques, text mining is producing breakthrough performance improvements, promising future applications, and practical use cases across many fields. Likewise, even though several attempts have been made in the field of financial information, few cases apply the current technological trends. Recently, companies and government agencies have attempted to conduct research and apply text mining in the field of financial information. First, in this study, we investigate various works using text mining to show what studies have been conducted in the financial sector. Second, to broaden the view of financial application, we provide a description of several text mining techniques that can be used in the field of financial information and summarize various paradigms in which these technologies can be applied. Third, we also provide practical cases for applying the latest text mining techniques in the field of financial information to provide more tangible guidance for those who will use text mining techniques in finance. Lastly, we propose potential future research topics in the field of financial information and present the research methods and utilization plans. This study can motivate researchers studying financial issues to use text mining techniques to gain new insights and improve their work from the rich information hidden in text data.

The purpose of this research is to validate the determinants of information systems(IS) sourcing strategy focusing on Korean financial institutions. Based on the factor analyses and discriminant analyses using data from 34 major Korean financial institutions, we observed that determinants of IS souring strategy are perceived risks, strategic expectations and organizational IS maturity. If the clients have clear objectives, can control the risks from IS sourcing, and have information systems in the less-matured stage, they frequently outsource their IS. In view of the IS maturity, previous studies suggest that more-matured IS are outsourced. But the results of this study show that more-matured IS are insourced. These phenomena can be explained by classifying IS by their functions. Transaction processing systems, which are mission-critical, are generally insourced, but decision support systems, which are in their mature state, are generally outsourced.

Although financial information is a great influence upon determining of the group which use them, detection of management fraud and earning manipulation is a difficult task using normal audit procedures and corporate credit evaluation processes, due to the shortage of knowledge concerning the characteristics of management fraud, and the limitation of time and cost. These limitations suggest the need of systemic process for !he effective risk of earning manipulation for credit evaluators, external auditors, financial analysts, and regulators. Moot researches on management fraud have examined how various characteristics of the company's management features affect the occurrence of corporate fraud. This study examines financial characteristics of companies engaged in fraudulent financial reporting and suggests a model and system for detecting GAAP violations to improve reliability of accounting information and transparency of their management. Since the detection of management fraud has limited proven theory, this study used the detecting method of outlier(upper, and lower bound) financial ratio, as a real-field application. The strength of outlier detecting method is its use of easiness and understandability. In the suggested model, 14 variables of the 7 useful variable categories among the 76 financial ratio variables are examined through the distribution analysis as possible indicators of fraudulent financial statements accounts. The developed model from these variables show a 80.82% of hit ratio for the holdout sample. This model was developed as a financial outlier detecting system for a financial institution. External auditors, financial analysts, regulators, and other users of financial statements might use this model to pre-screen potential earnings manipulators in the credit evaluation system. Especially, this model will be helpful for the loan evaluators of financial institutes to decide more objective and effective credit ratings and to improve the quality of financial statements.

Until now, systems in financial companies have been constructed and operated based on great mainframe proved being stability. But it has had many disadvantages since they only implement maintenance adding and changing function. So they need construction of new systems(development of critical application, integration of various service channel, management of customer data). In spite of great construction costs and high risk, it is necessary that they construct e-financial system. Nowadays financial institutions must actively offer services to customers. In other words, the key of service is being moved from providers to customers. In oder to develop and sell new products in a timely manner, integrated management about appropriate and valid customer data is needed. And new system that covers expanded area of work is needed since the original parts of the area is being broken gradually. In this paper, we search construction processes of e-financial system of Nonghyup to respond to new financial environment flexibly and actively, concrete contents about innovation activities of e-financial system and the cases of service utilization. Also, we suggest the development direction of e- financial system for Nonghyup following day.

Debt was defined as all kinds of borrowings made by families in including credit card debt. The purpose of the study was to investigate the effects of family debt management on financial satisfaction. A model of debt management and financial satisfaction was developed based on the Deacon-Firebaugh's systems approach to family resource management and the variables comprising input throughput and output were based on the theoretical background asnd previous researches. Data were collected from 763 households' money managers residing in Seoul during Summer of 1995 and the statistical methods utilized included correlation coefficient multiple regression and path analyses. It was responded about 82% of the households had been indebted indicating the use of debt being a general way of living in this society. The results showed that financial satisfaction lowered with larger amount of monthly debt payment and with their uncertiainty regarding their capability to repay debt. The input which exerted direct effects on financial satisfaction were income asset financial expectations and family life cycle. And consumption demand on debt and easiness in extending credit had strong indirect effects on financial satisfaction via the throughput variables. The most powerful predictor of financial satisfaction via the throughput variables. The most powerful predictor of financial satisfaction was perceived difficulty in managing debt which was the instrumental output.

Purpose This study aims to analyse the impact of the development of fintech and the emergence of internet primary banks due to the increasing use of smartphones on the performance of traditional local banks from both financial and non-financial perspectives. Return on equity (ROE) and return on assets (ROA) are used to assess the performance differences between the two types of banks and how these differences are affected by their financial characteristics. Design/methodology/approach Using return on equity (ROE) and return on assets (ROA) as indicators, we identified the differences in operating performance between the two types of banks. In addition, this study analysed the impact of financial characteristics on profitability through regression analysis with various control variables. We further studied the impact of non-financial characteristics (customer reviews, social media reactions, etc.) on operating performance. Findings The net interest margin ratio of local banks had a positive impact, while the marketable securities ratio of Internet primary banks had a negative impact. The non-financial analysis shows that the number of customer reviews and social media reactions have a significant impact on the performance of Internet primary banks, suggesting that customer satisfaction and positive market perception are important factors in the performance of Internet primary banks.

Model-based decision support system (DSS) has acted as a crucial role in strengthening the business competitiveness by providing a way of modeling and solving real-world decision problems in a quantitative and scientific manner. It is even more important for trading OTC derivatives, which requires extensive financial-engineering expertise while actively reacting to the continuously changing financial market. This paper proposes a flexible model-based DSS architecture that can support user-friendly interface for executing and analyzing the models and can adapt to the changes of financial market seamlessly. For user-friendliness, we implement the user-interfaces (UIs) using Microsoft Excel, a very widely used spreadsheet program for its great generality and extensibility. Users can utilize the analysis results of DSS or reprocess them for their special needs through the UIs in the form of familiar spreadsheets easily. For adaptiveness to the markets, the proposed architecture is constructed based on the object-oriented concepts, which enables such changes as release of a new financial product can be updated into the system without any delay at the lowest cost. We investigate the practical benefits and limitations of the proposed architecture by a case study on the construction of Model-based Trading Support System (MTSS), performed by a commercial bank in Korea.

This paper investigates whether the use of Rainwater Harvesting Systems (RWHSs) to provide water for washing machines in Hong Kong residential buildings would be financially attractive. In such systems, rainwater is accumulated and reused for doing laundry, garden irrigation, flushing toilets, and even drinking. Thus, the analysis of RWHSs' financial feasibility is essential for construction projects. RainCycle is used to validate financial feasibility, considering particular circumstances and data relevant to the Hong Kong context. A range of different scenarios by adjusting three factors are evaluated: catchment area, water demand, and discount rate. It is suggested that $2,000m^2$ would be a suitable catchment area in a typical Hong Kong residential building and it is demonstrated how water demand and discount rate influence the financial performance of RWHSs. In particular, the financial performance of RWHSs is sensitive to discount rates. The results suggest that the RWH system would be worthwhile for buildings with a lower number of floors, but would barely achieve financial validation in Hong Kong's super high-rise residential buildings.
