  • In this study, The matrix method was used with common category concept according to the construction project control system. For the purpose of systematic resource management planning, it should be established on accomplished EVM data for clearing the ordering point according to the attribute procurement analysis. Resource management was presented by connecting the material requirement calculation method and the attribute of procurement method based on the EVM, suggested through analyzing process-data modeling using integrated schedule, cost and material.

  • Connecting with cost, schedule, and quality in a construction project, resource management is one of the essential management elements. However, the material requirement planning is built at the beginning stage of construction and needs various concerned factors, it is limited to build the resource management planning on enterprise level. The disconnected communication among managements makes impossible to control historical data. In the construction project control system, the core of management elements is to manage cost and schedule information, therefore material requirement planning should be established based on historical data about EVM which is intergating schedule and cost. In this study, a resource management system concerning material requirement planning and attribute of procurement is suggested by connecting the historical data of EVM and the material requirement planning.

  • Recently, the construction industry has been pursuing the rationalization of its various systems through informatization. Procurement is a highly important element of the construction process, as it is directly related to the cost and quality of a construction project. In addition, procurement management of resources is in an indivisible relation, so that it is significant to link each other effectively. This study proposed construction activity and basic data connected to cost summary work for the categorization and utilization of resources. This study connected that activity to detailed items of material and labor cost, and proposed a procurement planning model of resources by activity that can utilize all resources and information. In addition, this model can classify resources and information by various forms. We found that the utilization of this procurement planning model will be higher because it can grasp various problems that occur in the passive procurement and provide additional functions that can be modified.

  • ITU-R recommends general methodology to provide current and future mobile communication services and 12 parameters to calculate terrestrial spectrum requirements. In this paper we analyzed 12 parameters suggested by ITU-R Recommendation and provided a method to determine a specific parameter value in a specific region. We calculated spectrum requirements and network resources for year 2010 in Korean mobile environment by applying parameter values acquired in parameter analysis method of this paper. And we analyzed the variation of spectrum requirements by calculating spectrum requirements depending on variation of parameters for future mobile communication services.

  • 오늘날 급변하는 경영환경에서 기업은 존속과 성장을 위해 기업 내외부에 걸친 경영혁신의 노력을 끊임없이 전개하고 있다. 특히 자동차부품산업의 제조자원계획 업무는 기업의 자본(Money), 인력(Man), 물자(Material), 설비(Machine) 등과 같은 중요한 경영자원을 활용하여 부가가치를 창출하는 업무이다. 본 논문은 국내의 자동차부품 기업을 대상으로 기존 자재소요 계획(MRPI) 업무를 AS-IS 분석에 따라 문제점을 찾아내어 타 업무와의 수평적인 통합에 의해 MRP 업무를 혁신적으로 개선할 수 있는 방안을 도출하고, 제조자원 계획의 관점에서 새로운 TO-BE 모델을 도출함으로써 자동차부품 기업의 수주-생산-자재간의 업무연계를 통하여 제조자원관리(MRPII) 업무를 개선하고자 하였다.

  • 뉴스와 같은 정확한 정보를 제공하는 영상을 제작하는 과정은 많은 자원과 시간이 소요된다. 작성된 기사를 이용하더라도 영상 기반의 뉴스를 제작하는 것은 인적, 시간적인 자원의 투여가 불가피하다. 뉴스를 송출하기 위해 소요되는 시간을 줄이기에 현실적으로 어렵다. 따라서 우리는 이러한 문제를 해결하고 빠른 뉴스 영상 제공이 가능한 "뉴스 영상 생성 AI"를 개발하기로 하였다.

  • 소프트웨어에 대한 고객의 요구수준이 점점 높아지고 복잡, 대형화됨에 따라 개발인력, 예산, 기간 등 많은 개발 자원이 소요되는 추세이지만, 개발자 직관에 의한 정성적인 판단으로 소요자원의 과부족을 초래하는 원인이 되고 있다. 본 논문에서는 요구분석 단계에서 기존의 정성적 판단에 따른 문제점을 보완하기 위해 요구분석 프로세스를 수정/제안하고, 의사결정기법을 이용하여 요구사항을 정량적으로 분석하고 식별할 수 있는 방법을 제안하였다. 이를 위해 사용자 요구분석 프로세스 검증단계에서 요구사항 평가활동을 추가하고, 의사결정 모델을 이용한 요구사항 가중치 계산, 시스템 기능과의 관련성 평가, 중요도 가중치를 계산하여 요구사항에 대한 식별의 기준으로 삼는다.

  • This study was conducted to estimate the days to flowering based on the effective accumulated temperature at various altitudes in the Jiri mountain region and to compare growth and yield characteristics according to the sowing date of safflower (Carthamus tinctorius) four genetic resources (local variety, IT323225, IT333473, and IT333482). The safflower four resources were sown on March 29, May 3, May 13, May 24, and June 2. The days from sowing to flowering of the safflower four resources by sowing dates were in the order of the local variety (61.0 days), IT333482 (73.2 days), IT323225 (74.0 days), and IT333473 (74.2 days). The base temperature and effective accumulated temperature for the days to flowering of the safflower four resources calculated based on the daily mean temperature were local variety 6℃, 579℃, IT323225 11℃, 766℃, IT333473 11℃, 768℃, IT333482 10℃, 750℃, respectively. As a result of applying the calculated effective accumulated temperature and daily mean temperature of the past five years (2019 to 2023) by various altitudes and the different sowing dates (every 15 days from April 1 to August 15), the days to flowering of the safflower four resources decreased from April 1 to July 15 during the sowing date and then tended to increase from August 1. In addition, the days to flowering at various altitudes were investigated in the order of plains, mid-mountain, and mountain regions. Among the yield characteristics, plant height, number of branches, number of capitula, number of seeds, and seed weight decreased as the sowing dates were delayed for the safflower four resources.

  • 2000년 연도표기 문제를 해결하면서 느낀점은 병행처리 기간의 기존 시스템의 PSI리포트에 오류가 발생하게 될 수도 있으므로 당장 시작해도 빠르지 않다는 것이다. 그리고 예상보다 인력, 시간, 컴퓨터 자원등의 많은 자원이 소요된다는 것이다. 단순하고 쉽다는 인식은 금물이며, 기본에 충실한 기존의 인프라를 활용하여야 하고, 점검한뒤에도 또 재점검을 하여야 한다.
