In the current construction industry, difficulty arises in creating an adequate baseline schedule to establish a fundamental plan for construction. This presentation will present the research findings which investigated industry-recognized schedule metrics that aid in the successful implementation of said schedule. Industry organizations (Association for the Advancement of Cost Engineering, the Government Accountability Office, the Project Management Institute, and local city, state, and county government offices) provide standardized guidelines with specific metrics requirements to ensure successful implementation. However, most of those metrics are substantiated or validated in their effectiveness. The study examined the impact between these industry-recognized critical metrics and three distinct scheduling characteristics: Project Type, Project Duration, and Project Density (number of activities within a schedule). The research results showed that, among the 12 various schedules evaluated in parallel with 20 industry-recognized critical metrics, seven metrics substantially demonstrate a significant impact on a project schedule's success. Furthermore, six of the seven metrics directly correlate to at least one of the three scheduling characteristics outlined. As a result, this research has established more predictable outcomes based on impacts between three distinct project characteristics and 20 of the most discussed/researched critical scheduling metrics in the field. This allows management teams to have more confidence in establishing critical milestones and accurate turnover dates from the start of the project through its final completion.

The Digitalia MUNI ARTS - a local node of the LINDAT/CLARIAH-CZ research infrastructure at the Faculty of Arts of Masaryk University constitutes a repository in the Islandora system. It is used for long-term preservation of research data together with their research environment in the form of digital platforms. We transfer the digital outputs of humanities scholars research to the repository according to a set plan, which is based on best practice recommendations for project management and digital curation. In this paper, we present how the results of interviews with platform developers and infrastructure stakeholders translate into the curation workflow, and a resulting model for migrating digital platforms to the repository. Reflecting on three types of problems we encountered during the implementation of platforms into the repository - communication problems, problems of external dependence, and management problems - we describe a modification of the migration process. We present six recommendations for repository administrators and curators in an academic setting - holding an introductory meeting with developers, researching significant and relevant theories of knowledge domain, consulting license experts, prioritizing requirements, and preparing handover protocol and progress reports.

Recently, in digital agriculture, the types and utilization of greenhouses based on IoT are spreading, and greenhouses are being modernized, enlarged, and even factoryized using smart technology. However, a specific standardization plan has not been proposed according to the equipment for data collection in the smart greenhouse and the size or shape of the greenhouse. In other words, there is a lack of standard data for facility equipment, such as the type and number of sensors and equipment according to the size of the greenhouse, the type of greenhouse construction film and materials suitable for crops and carbon neutrality. Therefore, in this study, the suitability of the implementation, installation and quantity of IoT equipment for data collection was tested, and some standard technologies were presented through the implementation of data collection and communication methods. In addition, impact strength, tensile, tear, elongation, light transmittance, and lifespan issues for PE, PVC, and EVA, which account for about 90% of existing greenhouses, were presented, and the shape, size, and environmental problems of greenhouses made of films were presented. presented in the text. In this research paper, a standardized carbon-neutral modular smart greenhouse using nano-material film was implemented as a solution to environmental problems such as greenhouse size, farm crop type, greenhouse lifespan, and film, and its performance with existing greenhouses was analyzed and presented. Through this, we propose a modularized greenhouse that can be expanded or reduced freely without distinction in the size of the greenhouse or the shape of farmhouse crops, and the lifespan is extended and standardized. Finally, the average characteristics of greenhouses using existing PE, PVC, and EVA films and the characteristics of greenhouses using new carbon-neutral nanomaterials are compared and reviewed, and a plan to implement an expandable IoT greenhouse that supports carbon neutrality is proposed.

The purpose of this study was to identify obstacles by surveying dieticians' perception in implementing Generic HACCP Plan for school foodservice operations from 2001. The survey was conducted in five areas; Seoul, Kyoung-gi Province, In-cheon, Kwang-ju and Dae-jeon. Five hundred and sixty questionnaire were sent by the e-mail address and the local school dietician's Community Board on the internet, 263 were returned. Two hundred and forty were returned by E-mail, return rate was 42.86%. Twenty three were received by the local school dietician's Community Board on the internet. The obstacles were grouped of six fields and indicated thirteen factors in implementation of the Generic HACCP Plan for school foodservice. The six fields were 'status of cooperation within HACCP team', 'cooperation with the external people' such as teachers, food suppliers, student's parents, 'understanding HACCP system of the dieticians', 'hygiene facilities', 'training & educating employees', and 'difficulty of monitoring'. To assess the factor as a obstacle we used Likert's scale; 5-agree strongly, 4-agree, 3-medial, 2-don't agree, 1-don't agree strongly. Results of this study are as follows; 1) The scores of thirteen factors indicated as obstacles were over 3(medial) except ‘lack of dietician's understanding about HACCP System(2.86$\pm$0.97)'. Also only about 63% dieticians recognized that as an obstacle factor. 2) ‘Deficiency of hygiene facilities(4.41$\pm$0.76), ‘lack of teachers' cooperation(4.23$\pm$0.77)', ‘inadequacy of the kitchen lay-out(4.19$\pm$0.95)' and ‘lack of training and educating program for employees(3.97$\pm$0.85)' scored most highly. Results from this study show that financial resources and educating system are very important to settle down HACCP system for School Foodservices successfully.

The aim of this study was to investigate how implementation of direct nutrition education differs between nutrition teachers and dietitians in Gyeonggi Area. In this study, we collected data from 107 nutrition teachers and 129 dietitians in 2012. Among those who have answered they implemented direct nutrition education for the last one year, 36% were nutrition teachers and 10% were dietitians (p < 0.05). Among subjects who implemented direct education, a significantly greater percentage of nutrition teachers used a class as an education time to conduct creative hands-on-activity compare to dietitians (p < 0.05). However, for most dietitians, school meal time was more commonly used for direct nutrition education. When asked to make a suggestion regarding improvement for school nutrition education, the highest rate of people chose simplification of school administrative work (4.68 points) was needed. Developing nutrition education (4.55 points) showed the next highest rate. The rest of the answers were the following order; regular training of teaching methods (4.50 points), increasing awareness of school teachers (4.50 points), improving school facilities and financial support (4.47 points), preparing teaching plan (4.46 points), providing incentive for direct education (4.26 points), organizing regular class for nutrition education (4.17 points), and placing nutrition teachers (4.16 points). This study provides useful information including manageable workload of nutrition teachers and dietitians, capacity building and supportive school environment to be delivered with respect to nutrition education system in South Korea.
