The purpose of this study is to discover the occupational identity by examining the narrative of the life of a TVET teacher using the project method in programming fields. Teacher S, a participant in the study, started as a part-time lecturer at university and has been teaching programs for the past 20 years. As a result, six kinds of occupational identities of a programming teacher who teach by project method were found. S experienced pride and pride as a teacher through the project method. The project method served as a motive for continuous self-development to lead S to an expert. His experience as a positive teacher made him wish to maintain this life and live as a teacher as long as his health permits, even after retirement. This study has significance in exploring the structure of the occupational identity of a TVET teacher using the project method in programming fields, which have not been studied yet.

많은 나양한 교수법들이 존재하지만 일반적으로 공학 교과목에서는 PBL교수법과 프로젝트 팀 교수법을 가장 많이 사용하고 있다. 본 논문에서는 2018년 2학기 공학 프로그래밍 교과목을 3개를 선정하여 PBL 교수법과 프로젝트팀 교수법을 적용하였고, 두 교수법의 학습만족도, 교육성장도, 학업성취도를 설문조사하여 학습효과를 분석하여 보았다. 그 결과는 저학년은 PBL법이, 고학년은 프로젝트 팀 교수법이 학습효과가 좋았다. 따라서 같은 프로그래밍 교육이지만 학년에 따라 교수법을 달리 선택할 필요가 있다.

The purpose of this study was to investigate the effects of learning achievement by comparing project approach group and the control group on the unit of growing flowers and vegetables in practical arts education. For this purpose, the experimental study on the unit of growing flowers and vegetables was achieved with 63 students(5th grade 2 classes) in S elementary school. The project approach model (Chung, Sung-bong) was applied to the experimental group, and the traditional model to the control group. To verify the effects of each class, nonequivalent control group post test-only design was applied 10 times. The SPSSWIN(ver 12. 0. 1) was used for analyzing the frequency and t-tests. The results of this study were as follows ; First, there was significant effect of learning achievement(cognitive domain) in the project approach groups. In addition, learning achievement of the experimental group has been showed significant difference about intellectual function and ability but not about knowledge. Second, there was significant effect of learning achievement(psychomotor domain) in the project approach groups. In other words, there has been showed significant difference in basic skill and integrated skill for growing flowers and vegetables but not in elemental skill for planting. Third, as the post test, there existed significant effect(affective domain) in the project approach groups. In other words, there was a meaningful difference in acceptance, value, belief, actualization but not in interest. Based on these results, It is believed that the project approach model in the unit of 'growing flowers and vegetables' is more effective than the traditional learning method in learning achievement of learners' cognitive, psychomotor and affective domain.

The purpose of this study is to draw implications through a case study on the curriculum operation of a professor who operated a programming subject as a PBL(project-based learning) method in an untact situation due to COVID-19. A survey was conducted for first-year freshmen students to determine their learning condition before project implementation. Based on the results of the questionnaire, individual interviews were conducted to identify the needs for education, and then, basic grammar for project completion and lectures that segmenting each stage of the project were composed. Repeated learning was induced through weekly quizzes, and feedback was given by giving time in advance until the project deadline. 23 students (40 students in total) completed the project. The remaining 17 students took the exam but did not complete the project. The purpose of this study is significant in that it investigated whether a project can be carried out through instructional design, execution, and interaction while operating a programming subject through PBL in the COVID-19 environment.

본 연구는 신산업분야 특화 선도전문대학 지원사업 연구를 통해 개발된 CK-AR/VR PBL 교수법을 팀 프로젝트 기반의 캡스톤디자인 정규 교과목 수업에 적용해봄으로써, 해당 교수법의 장점 및 문제점을 파악하고 활용방안을 모색하기 위해 진행되었다. CK-AR/VR PBL 교수법은 기존 PBL(문제중심수업) 교수법의 특징과 장점을 유지하고 AR/VR 게임콘텐츠 특성에 맞는 특징을 중심으로 구축된 교수법으로 15주 정규교과목 수업인 '취업과창업을위한차세대게임창작프로젝트(캡스톤디자인)' 수업과 '취업과창업을위한차세대게임 포스트프로덕션(캡스톤디자인)' 수업을 수강한 200여 명의 학생에게 적용하였고 장단점을 파악하게 되었다. 이를 바탕으로 게임 개발 팀 프로젝트 교육과정을 운영 중인 교육 관계자들이나 앞으로 유사한 교육과정을 운영하기 위해 준비 중인 교육 관계자들에게 조금이나마 도움을 주고자 한다.

This study aimed to identify the effect of the instruction applied with a project method for the 'Making Model by Architecture' unit in vocational High schools on the improvement of the Key competences. With this aim, the study selected as an experimental group, control group third graders in two classroom in G vocational High Schools in Goyang, Gyeonggi-do. Aiming at the selected students in the experimental group and the control group, the study conducted a pre-test of their Key competences; thus, the study confirmed that there was no statistically significant difference. Then, the study offered a class applied with a project method to the experimental group, while offering a traditional instruction to the control group. After offering the class, the study undertook a post-test, and verified the effect. In order to prove the test result, the study carried out a Hest using the SPSSWIN 12.0 statistical program, while the significance level being ${\alpha}$<.05. The conclusions obtained from this study include the following. All the six selected areas including 'problem-solving skills', 'communication skills', 'resource utilization competence', 'mathematical competence', 'interpersonal management competence' and 'self-management competence', which were supposed to be appropriate for this study among the sub-areas of Key competences, were found to show significant differences between the experimental group applied with a project method and the control group as a result of the post-test of the two groups. In summarizing the above research results, the class using a project method for the 'Making Model by Architecture' unit was discovered to be effective for improving Key competences. In particular, it may be more effective learning method for enhancing six areas greatly relevant to the project method among various sub-areas of Key competences.

Missing data is one of the common problems in building analysis or prediction models using software project data. Missing imputation methods are known to be more effective missing data handling method than deleting methods in small software project data. While K nearest neighbor imputation is a proper missing imputation method in the software project data, it cannot use non-missing information of incomplete project instances. In this paper, we propose an approach to missing data imputation for numerical software project data by combining K nearest neighbor and maximum likelihood estimation; we also extend the average absolute error measure by normalization for accurate evaluation. Our approach overcomes the limitation of K nearest neighbor imputation and outperforms on our real data sets.

For the successful performance of a private infrastructure project, an effective project financing is indispensable through various domestic/overseas sources. This study explains the concept of the private infrastructure development and investigates its current status in Korea. In addition, the details of the changed environment for the project finance under the newly enacted 'Private Investment Act' are compared in an analytical manner to those under the previous law. Finally, it discusses the problems that still remain and recommends the remedies available for the better financing environment.
