The square-based multiplication using look-up table simplifies the process and speeds-up the operating speed. However, the look-up table size increases exponentially as bit size increases. Recently, Wey and Shieh introduced a noble design of square generator circuit using a folding approach for high-speed performance applications. The design uses the ones complement values of ROM addresses to fold the huge look-up ROM table repeatedly such that a much smaller table can be sufficient to store the squares. We present new folding techniques that do not require a ones complement part, one of three major parts in the Wey and Shiehs method. Also the proposed techniques reduce the bit size of partial sums such that the hardware implementation be simplified and the performance be enhanced.

The purpose of this study is to evaluate current library cooperation system and to identify what fields should be cooperated with other libraries. A survey and group interviews are used for research method. The results show that only under 30% of respondents estimated the success of library cooperation system. The system needs to be changed. Online catalog and DB are evaluated as important fields, while the shared/cooperation acquisition is evaluated as less important field in current cooperation system. Also, education cooperation, the cooperation of education and culture programs, and advertisement cooperation are more necessary. The shared/cooperation acquisition is less necessary in library cooperation filed. The membership libraries of cooperation systems and library location are affected to responses as a factor. This study proposes two library cooperation systems: upload library cooperation system and download library cooperation system.

The government is operating a course evaluation-type qualification system for the purpose of overcoming the limitations of the test-type qualification system and cultivating talents with practical skills applicable to related industries. However, there is a part that does not match the purpose of the course evaluation qualification system by educating competency units in the field of surveying rather than the field of cadastral field in the education and training course of the course evaluation qualification. Therefore, this study closely analyzed the course evaluation qualification system in the cadastral field and suggested improvement plans accordingly. First, NCS in the cadastral field has not been supplemented or developed since its development in 2014, and there are many parts that do not conform to the current laws, so supplementary development is necessary. Second, It was proposed to improve the optional competency unit in the field of surveying to the NCS competency unit in the cadastral field. In addition, if the 12 competency units of the current NCS in the cadastral field are designated as essential competency units and education and training are operated, it will be possible to foster working-level talents with sufficient competency at the cadastral engineer level. However, for practical system operation and application, supplementation and development of NCS in the cadastral field, which is used for education and training of the course evaluation qualification system, must be preceded.

In urban as well as rural areas, there is a vigorous movement to establish cooperatives which are based on the Framework Act On Cooperatives. Eight months after the enforcement of the law, more than 600 cooperatives reported their articles of association to the competent Mayor/Governor in rural areas. Considering the population distribution in urban and rural areas, this is not a small number. Though recently established rural cooperatives are acting throughout diverse business sectors, cooperatives in agricultural sector, which engage in agricultural production, processing and sales, occupy the largest portion of all the rural cooperatives. There are two types of juridical person that are allowed to engage in the agricultural production, processing and sales by the laws. They are Farm Association and Agricultural Business Corporation. Now in rural Korea, farmers tend to establish cooperatives by the Framwork Act On Cooperatives which are in the same business sector with Farm Association or Agricultural Business Corporation. There are many needs to improve legislation regarding cooperatives. Above all, the laws about Farm Association and Agricultural Business Corporation are in urgent need of improvement for the emerging rural cooperatives to be treated fairly.

In an era where construction projects are becoming increasingly large and complex, the Korean construction industry faces the challenge of implementing systematic and cohesive schedule management practices. This study initially delineates the concept of schedule management capabilities, systematically categorizing them into five distinct domains: law and regulations, requirements of project owners, capabilities of professionals and organizations, task capability, and the adoption of smart construction technologies for schedule management. Through a survey targeting industry professionals, this research assesses the perceived importance and the actual proficiency level in schedule management across these categories, employing an Importance Performance Analysis(IPA) to scrutinize these capabilities. The findings underscore the acknowledged significance of diverse aspects of schedule management, yet reveal discrepancies between the current proficiency levels and their perceived importance, pinpointing areas necessitating enhancement. Critical improvement needs identified encompass the planning of budgets for schedule management, development of regulations for assessing construction periods, deployment of specialized on-site staff for schedule management, and investment in advanced schedule management software solutions. Consequently, this study offers a nuanced analysis and strategic insights for enhancing schedule management practices, aiming to facilitate their effective implementation in the field.
