Blockchain is a decentralized network in which data blocks are linked. Through a decentralized peer-to-peer network, users can create shared databases, resulting in a trustworthy and aggregated database known as a blockchain that enhances reliability and security. The distributed nature of the blockchain enables data to be stored on multiple nodes, eliminating the need for a central server or platform. This disintermediation significantly reduces the transaction and administrative costs. The blockchain is particularly valuable in applications where reliability and stability are critical because it establishes an open database that ensures data integrity, making it virtually impossible to tamper with or falsify data. This study explores the diverse applications of the blockchain technology in virtual assets, such as cryptocurrency, decentralized finance, central bank digital currency, nonfungible tokens, and metaverses. In addition, it analyzes the potential prospects and developments driven by these innovative technologies.

The purpose of this study is to investigate the current infrastructure of database on costume cultural heritage. The contents, kinds and accessibility regarding the digital contents of the websites of literature archives, museums and culturecontent.com by Korea Creative Content Agency were analyzed. First, it was evident that the quantity and quality of the database should be improved. The literature archives are mostly comprised of historical documents; however, the quantity of the database regarding the documents that are commonly studied in the field of traditional costume is not satisfactory. On the other hand, the quality of the database depends on the in-depth understanding of the terminology because errors occur when the contents of literature are transferred to an online database. Second, various information is required to meet the needs and interests of the digital environment. Most of the museums provide information on costume cultural heritage through their websites; nevertheless, it is not thorough and only partial. Third, the reliability of information needs to improve. The various contents provided by culturecontent.com lack reliability as it focuses on the entertainment values. To increase reliability, the source and origin of the information about the costume cultural heritage should be provided and the contents should be proofread before they are exposed to the public. Based on these findings, the researchers put forward the following suggestions: the quantity and quality of the databases should be enriched, and that more diverse information is required. Finally, more attention should be paid to increase the reliability of this information. This study will be an asset for the foundation to build solid databases and popularization of the traditional costumes.

The main objective of this research is to find out the effect of Non-Performing Loan (NPL) of Nepalese conventional banks. The population of this study is major commercial banks in Nepal and the data obtained for this study was from the period 2015-2019. This research used secondary data and it is collected from each bank's annual report and GDP and Inflation taken from the World Bank database. The method used for data analysis in this study is multiple regression analysis. The study used NPL as a dependent variable and Return on Asset (ROA), Capital Adequacy Ratio (CAR), Bank Size, GDP growth, and Inflation as independent/explanatory variables. The result of this research shows that ROA, Bank Size, GDP, and Inflation have a significant effect on NPL but CAR does not have a significant effect on the NPL of banks. In other words, the GDP effect on NPL in this study shows a positive and significant effect while most studies show a negative effect. It demonstrates that when GDP growth increases, there is a significant increase in the growth of Nepalese banks even though there were no significant changes in income growth. Therefore, GDP growth has a positive and significant effect on the NPL of commercial banks. Thus, the bankers and policymakers need to consider GDP growth carefully while taking NPL-related decisions.

최근 들어 개인 정보 보호의 중요성에 대한 인식이 매우 높아지고 있다. 많은 국가에서 개인정보 보호에 관련한 법규를 새로이 제정하고 있으며 이제 개인 신상에 관련된 데이터를 보호하는 것은 단순한 기업 이미지 관리 차원이 아닌 법적인 의무가 되었다. 대부분의 기업의 세일즈 데이터베이스에는 예외 없이 고객의 이름, 주소, 신용카드번호와 같은 정보가 저장되어 있다. 개인 정보는 개인 신상에 관한 민감한 정보이고, 또한 기업의 전략적인 자산이며, 따라서 기업은 개인 정보를 사전 예방차원에서 안정적으로, 그리고 포괄적으로 보호하기 위한 모든 노력을 다해야 한다. 그러나 만일 데이터베이스 관리자의 패스워드 보안이 뚫린다면 속수무책일 수밖에 없다. 이를 위해서 데이터베이스 암호화는 반드시 필요하다. 그러나 암호화의 결과 데이터베이스의 성능에 문제가 될 수 있고 또한, 암호화로 인하여 기존의 SQL 언어에서의 영역(range) 질의에 제한이 있다. 따라서 이와 같은 문제를 해결하여 암호화된 데이터를 효과적으로 질의하기 위한 방법을 본 논문에서 제안하였다.

As the IT technology develops there is a service on internet in which the herbal treatments from medicinal classics can be found in a form of a database. If an assay, and a verification on individual informations on materia medica and the herbal treatments from medicinal classics is established, it would be an enormously efficient asset for the formation of new treatment as well as interpreting the basic information on the efficacy of a treatment. If asp.net is used to make such a system, the user can have access to the informations on materia medica and its treatment without having to setting up a separate system, and especially the user can attain visual information on the genealogy of the herbal treatments in its formation. However, there is a need to develop a more efficient program in terms of organizing the informations on herbs and herbal treatments.

Since trees in the city are green assets that create a healthy environment for the city, systematic management of trees improves urban ecosystem services. The sporadic urban tree information centered on the site is vast, and it is difficult to manage the data, so efforts to increase efficiency are needed. This paper summarizes tree data inventory based on data constructed by Seoul Green Trust activists and constructs and discloses online database maps using Tableau Software. In order to verify the utilization of the map, we divided into consumer and supplier aspects to collect various opinions and reflect feedback to implement tree database maps for each area and species of Seoul Forest. As a result, the utilization value of tree database in urban parks was presented. The technical significance of this study is to systematically record the process of constructing and implementing a dashboard directly using the Mapbox platform and Tableau Software in the field of landscaping for the first time in Korea. In addition, the implications and supplements of landscape information were derived by collecting user opinions on the results. This can be used as an exploratory basis in the process of developing online-based services such as web and apps by utilizing landscaping tree information in the future. Although the visualization database currently constructed has limitations that ordinary users cannot interact in both directions because it utilizes business intelligence tools in terms of service provision it has affirmed both the database construction and its usability in web public format. In the future it is essential to investigate the assets of the trees in the city park and to build a database as a public asset of the city. The survey participants positively recognized that information is intuitively presented based on the map and responded that it is necessary to provide information on the overall urban assets such as small parks and roadside trees by using open source maps in the future.
