This paper presents a model for R&D project selection and evaluation system design developed through literature review. The model emphasizes the fitness between the five elements of the system : evaluation phase and purpose, personnel and organization, evaluation critiria and decision model, evaluation form and procedure, and projects. The model was applied in real situation as a test case. The important findings are that a good project selection and evaluation model contributes only partially to the effectiveness of the project selection and that system development and implementation activity is a dynamic and multi-facetted learning process.

Owner's participation on a construction project can alter the success of a construction project. In general, success of a construction project is measured by project schedule and cost decrease without considering the role an owner has in a project. As a result, this research developed a framework for the project evaluation form and after extracting a total of 9 project critical success factors (CSF) and 27 sub-CSF. AHP method was utilized to evaluate the importance factor of each CSFs. Setting a goal for each CSFs at the beginning of a project and comparing the values at the completion of the project utilizing the project evaluation form will allow a systematic evaluation and management of a project. Solution Map was introduced and Solution Tool was suggested in order to utlize the evaluation results effectively. In the future studies, various project cases needs to be supplemented for further verification and a solution based on the evaluation result needs to be developed that can be applied to construction projects.

Recently, the free-form buildings are continuously increasing in the world. However, due to the shortage of experience and technology in the project of the free-form buildings, problems such as increase of construction cost, increase of air and deterioration of construction quality are occurring. In this study, data on the 27 free-form projects in Korea and abroad using digital fabrication were collected through the journals, reports, articles, and websites of the institutes and case studies were conducted based on the collected data. Based on the following case analysis, we conducted evaluation of case data analysis based on the knowledge domain specified in PMBOK. Evaluation of case data analysis shows that the application of digital fabrication is divided into positive and negative effects for each knowledge area in the free-form building project. Using the results of the analysis, we can confirm the knowledge field showing the positive effect on the free-form building project by using digital fabrication. However, the data scale of the project using the digital fabrication is not realized at present and research is insufficient. In Korea, a small number of specialists were interviewed and verified because experts do not exist much in korea. Therefore, this study is expected to suggest the necessity of applying digital fabrication in the free-form building projects in the construction industry.

The construction liability type CM has been introduced in the form of a pilot project through public institutions since 2017 since it was introduced in the term of construction responsibility type construction project management in the Basic Law of Construction Industry in 2011 with the aim of improving the constitution of the Korean construction industry and strengthening global competitiveness. Through the introduction of construction-responsible CM, the government intends to change the paradigm of the overall construction industry, including design and construction, construction costs, disputes between stakeholders, and transparency of business. In this regard, the study aims to compare and analyze the evaluation methods on the bidding guide that public institutions (LH) are currently using to select companies in order to lay the foundations for successful construction of construction-responsible CM ordering methods.

Although the bottom-up rural area development project was conceived with great expectations, the general evaluation of the project so far reveals that it does not significantly differ from projects carried out in a top-down manner. This paper examines the nature of the bottom-up rural area development project with a focus on its background, including the roles of authority and project participants. Results revealed that the project was designed to be implemented in line with the state affairs ideology of the leader in a negative position of bureaucratic society. Though the form of implementation for the project seemed bottom-up as seen in the process of the roles and authorities in supporting organizations the top-down method of implementation can be seen in the authorities and roles of the central government. It was also noticed that the private sector, designed to elicit participation of various experts, looked to be managed and controlled by public organizations. The abovementioned signifies that the Korea rural area development project has been implemented not in a bottom-up manner but rather in an ever-strong top-down manner, which means that the central government holds more responsibility for the project's results, evaluation, and discussions. Furthermore, as seen in the background of the project, policies have been implemented in a top-down manner without the confidence of the bureaucratic society. Therefore, in order to implement a proper bottom-up rural area development project, there is a need for the bureaucratic society to have confidence in the rural societies.

This study has been performed with the purpose of making Rural Village Development Project Landscape Plan in which landscape characteristics in rural villages are reflected so that landscape in the medium to long term shall be established and managed. The issue that has been brought up is that procedures of Rural Landscape Plan and Rural Village Development Project Landscape Plan have been focused on facilities. The study carries out resources survey in agriculture, daily life and history and culture to make Rural Village Development Project Landscape Plan in O-chon district. Through landscape evaluation map participated by local residents, landscape management areas which they can form and manage have been established. The study also suggests Projects and guidelines appropriate to management areas. The study has a different signification from the existing Rural Village Development Project Landscape Plan which is fundamentally devoted to specific projects. The study shows Landscape Plan in the medium to long term and suggests guidelines available to be used by residents.

The resource constrained scheduling problem (RCSP) constitutes one of the most challenging problems in Project Management, as it combines multiple parameters, contradicting objectives (project completion within certain deadlines, resource allocation within resource availability margins and with reduced fluctuations), strict constraints (precedence constraints between activities), while its complexity grows with the increase in the number of activities being executed. Due to the large solution space size, this work investigates the application of Genetic Algorithms to approximate the optimal resource alolocation and obtain optimal trade-offs between different project goals. This analysis uses the cost of exceeding the daily resource availability, the cost from the day-by-day resource movement in and out of the site and the cost for using resources day-by-day, to form the objective cost function. The model is applied in different case studies: 1 project consisting of 10 activities, 4 repetitive projects consisting of 40 activities in total and 16 repetitive projects consisting of 160 activities in total, in order to evaluate the effectiveness of the algorithm in different-size solution spaces and under alternative optimization criteria by examining the quality of the solution and the required computational time. The case studies 2 & 3 have been developed by building upon the recurrence of the unit/sub-project (10 activities), meaning that the initial problem is multiplied four and sixteen times respectively. The evaluation results indicate that the proposed model can efficiently provide reliable solutions with respect to the individual goals assigned in every case study regardless of the project scale.

Purpose: The purpose of this study was to preliminarily evaluate the influence of diabetes mellitus (DM) on periodontal tissue without establishment of periodontitis. Methods: Seven-week-old db/db mice were used for the diabetic experimental group and systematically healthy mice of the same age were used as controls. After 1 week of acclimatization, the animals were sacrificed for hard and soft tissue evaluation. The pattern of bone destruction was evaluated by stereomicroscope evaluation with alizarin red staining and radiographic evaluation by microscopic computerized tomography images. Histological evaluation was performed with hematoxylin and eosin stain for evaluation of soft tissue changes. Results: In both stereomicroscope evaluation and radiograph image analysis, aggressive form of bone destruction was observed in diabetic animals when compared to the systematically healthy controls. In histological evaluation, apical migration of junctional epithelium with slight inflammatory cell infiltration was observed with disarrangement of connective tissue fibers. Conclusions: Within the limits of this study, diabetic animals presented distortion in periodontal attachment and an aggressive bone loss pattern when compared to the healthy controls, suggesting that DM has an independent effect on periodontal tissue destruction irrespective of the presence or absence of periodontal disease.
