포오트폴리오 평가란 하나 이상의 주제나 문제에 대한 해결 과정을 모두 기록함과 아울러, 이들에 대한 반성적 자기 평가 결과들을 모아둔 것으로 이를 통해 학생들은 자기 자신의 변화 과정을 알 수 있고 자신의 장점이나 약점, 성실성 여부, 잠재 가능성 등을 스스로 인식할 수 있다. 그리고, 교사들은 학생들의 과거와 현재의 상태를 쉽게 파악할 수 있을 환 아니라 앞으로의 발전방향에 대한 조언을 할 수 있다. 포오트폴리오 평가는 결과만을 중시하는 평가 방법이 아니라 과정 중심 평가 또는 과정과 결과의 통합 평가의 한 대안적인 방법으로 학습자의 자아실현을 위한 발달의 잠재적 가능성을 키워주는 중요한 도구로 이용될 수 있다.

한국 건설산업의 전략적 선진 프로젝트 매니지먼트 적용을 위해 유럽, 미국, 일본 등 선진국의 프로젝트 매니지먼트 지식체계를 비교 분석하였다. 그 결과 프로젝트 매니지먼트 지식체계의 이론적 배경 기반에는 '전략'의 '실행' 연계가 중요한 공통 이슈로 대두되며, 개별 프로젝트에서 복합 프로젝트를 관리 경영하는 통합 기반의 '프로그램 매니지먼트'와 선택과 집중을 하기 위한 '포트폴리오 매니지먼트'를 연계한 전략기획을 강조하고 있음을 알 수 있었다. 이에 본 연구에서는 한국 건설산업의 전략 실행을 위한 전략적 선진 프로젝트 매니지먼트 적용의 기본틀을 구축하고 현재 한국건설산업에 적용하기 위한 실천방안으로 1) 조직의 전략 실행을 위한 '이념과 철학' 구축으로 글로벌 경쟁력 혁신 2)조직의 문화와 구조를 고려한 전략적 '환경' 구축, 3) 조직의 실현 가능한 목표를 달성할 수 있는 전략적 '비전' 제시, 4)이러한 전략과 연계된 포트폴리오 매니지먼트를 통한 '투자', 5) 포트폴리오를 통한 프로그램, 프로젝트 매니지먼트 '실행' 그리고 마지막으로 이들의 통합체제 구축과 운영으로 '성과' 획득을 할 수 있도록 한국 건설산업의 전략적 선진 프로젝트 매니지먼트를 적용한 지속 가능한 발전 방안을 제시하였다.

Domestic construction companies are suffering from financing difficulties in the wake of the economic slump in Korea and abroad. During this economic slump, real estate investment trusts (REITs), facilitators for improving financing and stimulating construction businesses, have increasingly expanded since their introduction in 2001. However, in terms of growth speed and marketing size, Korean REITs are falling behind those of other nations. The purpose of this study is to suggest a method for composing a portfolio using the Markowitz portfolio selection model to stimulate REITs. The main contents are as follows. First, a comparative analysis was conducted of increased REIT profit with the application of the Markowitz model and the average REIT profit rate from July 3, 2007, to July 21, 2008, during the investment analysis periods. The results showed that the total profit rate from the Markowitz model was about 10% higher than the average REIT profit rate. Second, the sensitivity was analyzed according to the portfolio's data-gathering and replacement cycle to measure the optimum cycle and yield. The six-mouth profit data collection period showed about 16% higher profits with the Markowitz model than with the REITs. The two-week portfolio change period resulted in about 11% higher profits with the Markowitz model than with the REITs.

The purpose of this study was to present a class case that verified the validity, reliability, and usefulness of a portfolio assessment in a cohousing class in the housing area of home economics. To achieve this objective, 241 male and female students in eight classes of the third grade of a junior high school in Gyeonggi-do, Korea, were enrolled in a project class on establishing a cohousing village in which the portfolio assessment method was applied for a total of 10 sessions for approximately four weeks from May 24 to June 16, 2021. To ensure the validity of the portfolio assessment, we designed the lesson after presenting the curriculum goals in detail using the backward design model and developed a specific rubric and conducted all evaluations and feedback based on the rubric to ensure objectivity and reliability. The online tool Padlet was used as a portfolio, which allowed students to easily upload their work, receive feedback from the teacher, and interact with their peers. After the class, the students reflected on the rubric and were generally satisfied with the class using portfolio assessment. This study is expected to facilitate the use of the portfolio assessment method in the classroom, while also supporting student growth and development.

For the balanced realization of these values of mathematical culture, we need to innovate mathematics classrooms, for which we need to make use of portfolio assessment. First, portfolio assessment can be regarded as a method of synthesizing a variety of resources for systematic evaluation. Second, portfolio assessment can be used as a tool of building up learners' positive attitude toward mathematics, by which we can identify the latent possibility of learners' development and help them develop confidence in mathematics. Third, portfolio assessment can play an important role as a tool for exploring the method of teaching and learning in which learners recognize the value of mathematics and are interested in mathematical activities, as we have seen in the report on the Gulliver's Travels Project.

This purpose of this study is to suggest a tentative model for project selection of information system. In constructing a mathematical model, quantification of decision criteria is tried to lessen difficulties of measuring benefits of information system project. Suggested model enables us to select projects in the context of portfolio and information system policy.

The purpose of this study is to integrate Decision Theory Approach(DTA) and OR Theory Approach(OTA) systemically. and to develop Combination Theory Approach to build an optimal R&D project portfolio by strategies. To Integrate two approaches. Utility theory is introduced. Evaluation Results aye converted into utility values by the utility functions and the values are optimized by 0-1 programming. Scoring method and Integer programming is used to evaluation a correspondence with a goal and to allocation the limiting resources. And utility function is used to reflect the preference of decision makers on the project evaluation.

Risk evaluation approaches for bidding on international construction projects are typically partitioned into three stages: country selection, project classification, and bid-cost evaluation. However, previous studies are frequently under attack in that they have several crucial limitations: 1) a dearth of studies about country selection risk tailored for the overseas construction market at a corporate level; 2) no consideration of uncertainties for input variable per se; 3) less probabilistic approaches in estimating a range of cost variance; and 4) less inclusion of covariance impacts. This study thus suggests a three-staged risk evaluation model to resolve these inherent problems. In the first stage, a country portfolio model that maximizes the expected construction market growth rate and profit rate while decreasing market uncertainty is formulated using multi-objective genetic analysis. Following this, probabilistic approaches for screening bad projects are suggested through applying various data mining methods such as discriminant logistic regression, neural network, C5.0, and support vector machine. For the last stage, the cost overrun prediction model is simulated for determining a reasonable bid cost, while considering non-parametric distribution, effects of systematic risks, and the firm's specific capability accrued in a given country. Through the three consecutive models, this study verifies that international construction risk can be allocated, reduced, and projected to some degree, thereby contributing to sustaining stable profits and revenues in both the short-term and the long-term perspective.

Sequentiality in decision making is an inherent characteristic of the R&D Process, Conceptual changes are noted during the Course of the Project which represent a continuous improvement in the quality of the data available during the various project stages. In this paper, Eight characteristic types of project evaluation models have been developed economic index models, portfolio models, decision theory models, risk analysis models, frontier models, scoring models, profile models and checklists. Each of these will be critically reviewed and appraised.
