In this paper, we propose a framework for multi-focus image fusion called PATN. In our approach, by aggregating deep features extracted based on the U-type Transformer mechanism and shallow features extracted using the PSA module, we make PATN feed both long-range image texture information and focus on local detail information of the image. Meanwhile, the edge-preserving information value of the fused image is enhanced using a dense residual block containing the Sobel gradient operator, and three loss functions are introduced to retain more source image texture information. PATN is compared with 17 more advanced MFIF methods on three datasets to verify the effectiveness and robustness of PATN.

Purpose - This study aims to clarify the meanings of small enterprise and modify criteria for explaining its range. Prioritizing the number of full time workers first and the sales next are proper as a new concept and range. Research design, data, and methodology - In research, 'small company' is a basic concept because the range of its standard is categorized as a 'small company' in the policy system of small & medium business. This study focuses on the solutions with ① evaluation on sales, ② standard for excluded ones ③ regulation for excluded business types in 'Act on Protection and Support for Small Enterprise'. Results - Clarifying the range of standard with maintaining the title is advisable. The scope should resist the current criteria or adopt a new standard which contains not only full time workers but also the sales. The new one may raise the policies' effectiveness because it can sort the 1% people of small enterprises. Conclusions - However, there should be a preventive system for sorting out the non-eligible ones not conformed to the CAP for small company. Therefore, it is desirable to prepare the system with 'unsuitable ones list' or regulate large income·inappropriate business types in 'Act on protection and support for small enterprise'.

Considering the current situation where cash transactions account for 51.5% of private consumption expenditure, it is very important to secure a tax base by exposing business operators' cash transactions. In the September 2011 national audit, it was pointed out that although a significant part of the investment amount of businesses (VAN operators, etc.) related to the issuance of cash receipts has been recovered, they are still supported through the state tax. At this point in time when a significant amount of the initial investment has been recovered, it is necessary to study a new way to support business operators through methods other than the tax credit method. This study proposes various methods to improve the current cash receipt system and describes the advantages and disadvantages of each method. The most important thing for the improvement of the cash receipt system is that the issuance of cash receipts should be beneficial to business operators. As a result of this study, the most desirable improvement method is to provide differential compensation for the discriminatory cost because the cost is different for each cash receipt operator. For this purpose, we analyze the best way to improve the cash receipt system is a tax credit method and a tax credit for maintenance costs.

Domestic urban railway are operated by urban railway operating public enterprises, which are owned by the 6 major metropolitan local governments and private operating companies, which are established under the Private Investment Act. Among urban railway operating companies, several public enterprises that operate urban railways with many experience, performance, human resources, and public nature are making efforts to promote overseas business. Therefore, this study examines the outlook for railway and urban railway overseas business, and provides implications for the overseas business approach of domestic urban railway operating public enterprises through data research and comparative analysis on the overseas business approaches and overseas business characteristics of domestic and foreign urban railway operating public enterprises. The results were derived and suggestions for the direction of overseas business were presented. I expect that suggestions will serve as a reference for domestic urban railway operators to promote overseas projects with preparation, implementation plan and direction.

Cloud computing is rapidly increasing for achieving comfortable computing. Cloud computing has essentially security vulnerability of software and hardware. For achieving secure cloud computing, the vulnerabilities of cloud computing could be analyzed in a various and systematic approach from perspective of the service designer, service operator, the designer of cloud security and certifiers of cloud systems. The paper investigates the vulnerabilities and security controls from the perspective of administration, and systems. For achieving the secure operation of cloud computing, this paper analyzes technological security vulnerability, operational weakness and the security issues in an enterprise. Based on analysis, the paper suggests secure establishments for cloud computing.

Objectives: Business operators handling hazardous chemicals regulated under the Chemical Substances Control Act (CSCA) must receive permits to operate their business from the Ministry of Environment. This study analyzed the status of recent legal violation in chemical handling workplaces in Ulsan where a large volume of chemicals is handled for industrial use. Methods: A total of 557 corporations have been granted legal status as business operators in Ulsan. For all business operators, legal violations in regard to the CSCA that were discovered by the environmental office in the last five years (2018~2022) were thoroughly analyzed. Results: A total of 225 violations of the CSCA have been discovered at 165 corporations, with the violation rate accounting for approximately 27% of all business operators. In particular, 22% of the 165 violators (36 corporations) were discovered to have violated twice or more, and some business operators (6%) even violated in consecutive years. Non-compliance of facility inspection was the most frequent violation (45 cases, 20.1%), followed by non-reporting of important changes in the permitted matters (23 cases, 10.3%), non-completion of legal safety education (19 cases, 8.5%), failure to secure permission for modification in the permitted matters (18 cases, 8.0%), and failure to submit chemical transport plans (16 cases, 7.1%). Conclusions: Most of the violations could have been prevented if the field personnel had paid sufficient attention. Thus, it is fundamentally necessary to create an environment for spontaneous safety management for themselves and to strengthen individual capabilities.
