Mutual Savings Banks generally have weaker governance structure than other financial institutions, so the possibility of earnings management by owner-largest or managements of mutual savings banks is higher than other financial institutions. This study examines the relationship between corporate governance and quality of internal control of financial reporting. If the expropriation of minority shareholder hypothesis holds, we predict that the larger block shareholder in mutual savings banks, the weaker the internal control system by more likely the opportunistic earnings management by bank managers. On the other hand, under the convergence of interest hypothesis, we predict that the larger block shareholder in mutual savings banks, the stronger the internal control system by reduction in agency costs as owner-manager's holdings increases, and there a negative relationship is expected between internal control weakness and the holdings of the owner-largest shareholder. We find that mutual savings banks with higher owner-largest shareholder equity has significant positive relations with their internal control of financial reporting material weakness. This result suggests that the greater owner-largest shareholder equity, the more likely the opportunistic earnings management, so that decrease quality of internal control. This paper extends the literature on financial institutions corporate governance to verify whether governance system, especially, owner-largest and quality of internal control has significant positive relations.

Paddy fields not only provide a variety of ecosystem services but also serve as crucial habitats for biodiversity conservation. Recently, their ecological value and significance have been increasingly emphasized. Therefore, this study aimed to investigate the characteristics of soil seed banks and analyze their correlation with soil environmental factors in Conventional Paddy field (CP) and Organic Paddy field (OP) with different farming practices. Our results revealed that the vegetation in CP was simple, resulting in low plant diversity in the soil seed banks. On the other hand, the vegetation in OP was relatively diverse, leading to higher plant diversity in the soil seed banks. Additionally, distinct differences in soil environmental characteristics were observed between OP (K, Ca, Mg, Na, Fe, Mn, B↓) and CP (K, Ca, Mg, Na, Fe, Mn, B↑). These results suggest that variations in agricultural practices for rice cultivation have influenced the structure and diversity of vegetation and soil seed banks. Furthermore, these agricultural practices have had both direct and indirect effects on soil environmental factors. Our findings can serve as fundamental data for evaluating biodiversity conservation in agricultural ecosystems, ecosystem restoration, and ecological value assessment.

Soil seed banks at ecological preservation areas in Seoul, Jinkwannae-dong, Bangi-dong and Bam-sum, were studied by seedling emergence method from May to October 2004. Total number of species and individuals in seed banks were 42 and 5,190 at Jinkwannae-dong, 39 and 2,290 at Bangi-dong, and 39 and 1,047 at Bamsum. Salix koreensis community at Jinkwannae-dong has the highest number of seedlings among all sites. The most abundant species were Lindernia procumbens in Jinkwannae-dong and Bam-sum and Typha spp. in Bangi-dong. The dominant species of seed banks were different from that of plant communities such as Phragmites communis community, Salix koreensis community, Persicaria thunbergii community, Phragmites japonica community, and Populus tomentiglandulosa community. However the dominant species of seed banks in Typha community was Typha spp. Total 63 species emerged in either the wet or submerged conditions. Fifty six species appeared in the wet condition and 25 in the submerged condition. Eighteen species appeared in both conditions. Numbers of species and individuals were much less in the submerged condition than in the wet condition but free-floating hydrophytes including Rorippa islandica and floating-leaved hydrophytes including Monochoria vaginalis appeared only in the submerged condition. In the investigation of soil seed bank by distance from water edge (Bamsum), water side 3 ($300\sim350m$ from water) edge, where water level is fluctuating frequently, has the highest number of seedlings.

This study investigates regional financial markets and proposes some policy measures for boosting up the regional financial system. Financial supports for start-ups, small and medium sized enterprises(SMEs) in early stage growth have been constrained due to expanded financial gaps among regions during financial restructuring period. The bank consolidation through M&A is associated with widening financial gaps between Seoul area and others, and between regions where regional banks survives or not. Loans to small firms are associated with relationship lending techniques that may be better supported by smaller regional banks. The loan rate to SMEs in locals where regional banks are activated has tended to be 10%point higher than the locals where regional banks closed, and also drive the greater contribution for preventing local capital outflow and promoting local capital investment by local penetrating strategy. Government should develop regional financial policies to boost up regional financial system, and expand the business area of regional financial institutions for supporting start-ups and SMEs.

In this study, the development processes of multiple bars in the channels with erodible banks were investigated by double Fourier analysis. The initially straight channels in the experiment flume were widened with eroding the side banks, and the multiple bars were generated and grew due to stalling of the sediment on the bed. The bars migrated downstream and the size of the bars increased with time. The flow was separated around the bars, and the bed and banks near the bars were scoured due to the impinged secondary flow. The morphologic changes were accelerated by the bank erosion, which affected the fluctuations of sediment discharge downstream. The double Fourier analysis of the bed waves showed that 1-1 mode (alternate bar) was dominant at the initial stage of the channel development. As time increased, 2-3 mode (central or multiple bars) was dominant due to the increased width to depth ratio. Moreover, the number of bars in a cross section of the channel were increased due to the non linearity of alternate bars. The width to depth ratio was increased by the bank erosion, which affected the bar migration and the bar wavelength. However, the dimensionless tractive force was decreased by it.

This paper investigates factors determining the level of nontraditional activities at banks around the world. Specifically, the paper examines what kinds of firm-specific and country-specific characteristics determine the level of noninterest income using a comprehensive multi-country database. This paper focuses beyond the traditional U.S. based analyses and provides detailed asset-liability management practices of banks around the world.The findings suggest that banks' size and loan loss provision, explicit deposit insurance, banking restriction, banking freedom ranking of respective countries, the extent of state and foreign ownership, governance, and transparency of the country have positive effects on the level of nontraditional activities. Greater dependence on traditional lending and financing, market based economy, and multiple bank supervisory bodies in the country have negative associations with noninterest income. The economic development of country however affects the extent of the relationship.

The purpose of this study was to investigate the effects of perceived risk, perceived benefits and trust on the intention of continuous use of Internet primary banks in order to explore ways for stable establishment and growth of Internet primary banks. In addition, the mediating effects of trust on the relationships among perceived benefits, perceived risk and intention of continuous use were tested. Through an online survey, 457 people aged 20-59 years who had experience of using an Internet primary bank within the last 3 months were selected as the subjects for this study. First, perceived benefits, perceived risk, and trust were found to have a significant influence on the intention of continuous use of Internet primary banks. Second, the partial mediation effect of trust on the relationships of ease of use and functional risk with intention of continuous use was confirmed, and the full mediation effect of trust on the relationships of attractiveness and innovativeness with intention of continuous use was verified. In order to achieve sustainable growth, Internet primary banks are required to increase major benefits of customers and lower the risk levels to build firm customer trust.

Purpose - This study aims in analyzing the dynamic relationship between household loans and housing prices according to the characteristics of depository institutions after the financial crisis, identifying the recent trends between them, and making policy suggestions for stabilizing house prices. Design/methodology/approach - The monthly data used in this study are household loans, household loan interest rates, and housing prices ranging from January 2012 to May 2020, and came from ECOS of the Bank of Korea and Liiv-on of Kookmin Bank. This study used vector auto-regression, generalized impulse response function, and forecast error variance decomposition with the data so as to yield analysis results. Findings - The analysis of this study no more shows that the household loan interest rates in both deposit banks and non-bank deposit institutions had statistically significant effects on housing prices. Also, unlike the previous studies, there was statistically significant bi-directional causality between housing prices and household loans in neither deposit banks nor non-bank deposit institutions. Rather, it was found that there is a unidirectional causality from housing prices to household loans in deposit banks, which is considered that housing prices have one-sided effects on household loans due to the overheated housing market after the financial crisis. Research implications or Originality - As a result, Korea's housing market is closely related to deposit banks, and housing prices are acting as more dominant information variables than interest rates or loans under the long-term low interest rate trend. Therefore, in order to stabilize housing prices, the housing supply must be continuously made so that everyone can enjoy housing services equally. In addition, the expansion and reinforcement of the social security net should be realized systematically so as to stop households from being troubled with the housing price decline.

This study investigates channel stabilities with groynes by developing the assessment of it and applying a 2-dimensional numerical model, which simulates flow and sediment transport with various flows in the channel. Evaluation inventories are composed of five items, which are width to depth ratio, sinuosity, bed slopes, velocities in the flow flied, Shields number with discharges and geomorphic characteristics in the study reach. The channel stability is evaluated by applying the evaluation indicators to the channel with and without groynes in the study reach between Dalseong-weir and Gangjeonggoryeong-weir in the Nakdong river. Width to depth ratio, sinuosity, and bed slopes, which are index of river characteristics, little affect the channel stability. However, velocities in the flow flied, and Shields number, which is dimensionless tractive, near the banks of the channel strongly affect the stability. The evaluation values of the stability in the channel on the left and right banks decrease as the number of groynes increase in both the left and right banks, which means that the bank stability increases with the groynes.

The purpose of this study is to based on review of theoretical and empirical studies to assess the independence of central banks - the former Socialist republics, including the Russian Federation and Czech, Poland. In addition, the work is expected to clarify whether a link exists between independence and the most important economic indicators such as inflation, economic activity, the budget deficit. And The subject of this study are the formal and actual independence of national banks, as well as limiting factors: political and economic. Background investigation of the problem of independence of central banks from the fact that, according to many economists, it is essential to the successful development of a market economy. The effectiveness of any country's economy due to currency volatility, low inflation, high reliability of the banking system, etc. As far as the independence of monetary regulation contributes to these goals - one of the most actively debated issues in the world of economic theory and practice for a long time. The issue of central bank independence is extremely important for Russia, Czech, Poland. In the near future to the central bank has important tasks, among which are the transition to inflation targeting in the rejection of significant intervention in the foreign exchange market, as well as improving the sustainability of the national banking system. Transparency and independence of the Bank of Russia, Czech Republic, Poland, in my view, should be an important factor in achieving these goals. The countries of Czech Republic, Poland have already made a number of steps to bring the status of their banks to the European standards. Many other developing countries are also in the process of reforming their central banks and the improving conditions of their functioning. However, despite the fact that as a model for reform used by the central banks of countries with developed market economies, central banks in developing countries are still yet deprived of the legal, economic and political independence. A different situation exists in transition space. Because of significant differences in the views of the authorities in transition republics at the necessary level of independence of central banks and the exchange rate and monetary policy reform of monetary management in these countries led to different results.
