이미지와 같은 고차원 데이터로부터 새로운 샘플 데이터를 생성하는 기술은 음성 합성, 이미지 변환 및 이미지 복원 등에 다양하게 활용되고 있다. 본 논문은 고해상도의 이미지들을 생성하는 것과 생성한 이미지들의 variation을 높이기 위한 방안으로 Progressive Growing of Generative Adversarial Networks(PG-GANs)을 구현 모델로 채택하였고, 이를 패션 이미지 데이터에 적용하였다. PG-GANs은 생성자(Generator)와 판별자(discriminator)를 동시에 점진적으로 학습하도록 하는데, 저해상도의 이미지에서부터 계속해서 새로운 레이어들을 추가하여 결과적으로 고해상도의 이미지를 생성할 수 있게끔 하는 방식이다. 또한 생성 데이터의 다양성을 높이기 위하여 미니배치 표준편차 방법을 제안하였고 GAN 모델을 평가하기 위한 기존의 MS-SSIM이 아닌 Sliced Wasserstein Distance(SWD) 평가 방법을 제안하였다. Techniques for generating new sample data from higher dimensional data such as images have been utilized variously for speech synthesis, image conversion and image restoration. This paper adopts Progressive Growing of Generative Adversarial Networks(PG-GANs) as an implementation model to generate high-resolution images and to enhance variation of the generated images, and applied it to fashion image data. PG-GANs allows the generator and discriminator to progressively learn at the same time, continuously adding new layers from low-resolution images to result high-resolution images. We also proposed a Mini-batch Discrimination method to increase the diversity of generated data, and proposed a Sliced Wasserstein Distance(SWD) evaluation method instead of the existing MS-SSIM to evaluate the GAN model.

핵심역량 제고를 위한 교양 교육과정 개선: K대학 사례를 중심으로

김양희 ( Yanghee Kim ) 사단법인 아시아문화학술원 2021 인문사회 21 Vol.12 No.2

본 연구는 K대학의 사례를 중심으로 핵심역량 기반 교양 교육과정의 개선 내용을 공유하고 시사점을 도출하는 데 목적이 있다. 본 연구에서는 K대학에서 최근 2~3년간 진행한 교양교육 관련 연구 내용과 교양 교육과정 개선 성과를 제시하고자 한다. K대학은 역량기반 교양교육의 내실화를 위해 핵심역량을 재정립하고 교양교육 기본체계를 개편하였으며, 구성원들의 의견을 반영하여 교육과정을 편성ㆍ운영하고 자체 핵심역량 진단을 통해 역량기반 교양 교육과정 체계를 구축하였다. 그럼에도 불구하고 앞으로 재학생들의 핵심역량 함양 수준을 지속적으로 측정하여 진단도구의 타당성과 신뢰성을 확보해야 한다. 뿐만 아니라 핵심역량 함양을 위해 교과목별 특성을 반영하여 교수ㆍ학습 방법을 다양화해야 한다. 이러한 과제는 역량기반 교육과정을 운영하고 있는 많은 대학들이 함께 관심을 가지고 대응해야 할 내용으로, 환류에 관한 사례 공유를 통해 역량기반 교육과정 운영에 대한 발전적인 논의가 이루어져야 할 것이다. The purpose of this study is to share cases of improvement of core competency- based liberal curriculum and derive implications around the curriculum improvement process at K university. This study intends to present the contents of research related to liberal education and the achievements of improving the liberal curriculum conducted at K university for the past two to three years. In order to internalize competency-based liberal education, it reestablished its core competencies, reorganized the basic system of liberal education and established a competency-based liberal curriculum system by organizing and operating a curriculum reflecting the opinions of members, and conducting self-diagnosis of core competencies. However, the level of core competency cultivation of students should be continuously measured to ensure the validity and reliability of measurement tools in the future. In addition, it is necessary to diversify teaching and learning methods by reflecting the characteristics of each subject in order to cultivate core competencies. This task is a content that many universities that operate competency-based curriculum should respond with interest, and developmental discussions should be made through sharing cases of feedback.

다양한 종류의 피드백이 영어작문 향상에 미치는 효과

김양희(Kim, Yanghee),주미진(Joo, Mijin) 한국영어어문교육학회 2010 영어어문교육 Vol.16 No.4

There is disagreement, among researchers, on the benefits of corrective feedback on L2 learners' written output. Some scholars advocate the usefulness of corrective feedback while some claim that error correction is ineffective and even harmful. So far, however, research outcomes cannot settle this debate. Based on this debate, this study examines whether there is a difference among diverse types of feedback on the effects of L2 learners' writing improvement. This study found that teacher’s direct feedback was more effective than any other types of feedback on the effect of participants' writing improvement. In particular, teacher's direct feedback helped their improvement on grammar, mechanics, and form. Among the types of peer feedback, self-correction was the most effective. In teacher feedback, form-focused feedback had more effects than content-focused feedback, but no difference with regard to peer feedback. In addition, teacher's content-focused feedback was more effective than peer's content-focused feedback. Overall, in all types of feedback, teacher feedback was more effective than peer feedback. However, direct (form-focused) feedback was the most effective in teacher feedback, and self-correction in peer feedback. The least effective feedback in both teacher and peer feedback was indirect (form-focused) feed back, which is simple underlining of errors.

김양희(Kim, YangHee),김희승(Kim, HeeSeung) 학습자중심교과교육학회 2017 학습자중심교과교육연구 Vol.17 No.12

본 연구는 간호대학생의 자기주도적학습 촉진을 위한 교수자 스캐폴딩을 적용 하여 학습 태도, 비판적 사고성향 및 자기주도학습능력을 통해 확인하고자 수행되 었다. 연구설계는 수업요구도 조사는 조사연구, 교수자 스캐폴딩 적용 효과는 단일군 사전사후설계에 의한 유사실험연구이다. 연구 대상은 수업요구도 조사는 3학년 196명, 4학년 191명, 스캐폴딩 적용 효과 연구는 4학년 123명 이었다. 자료수집은 2016년 3월에 학습요구조사 및 사전조사를 실시하였으며 교수자 스캐폴딩 적용 후 6월에 사후조사를 실시하였다. 수집된 자료의 처리는 SPSS/WIN 21.0 프로그램을 활용하였다. 연구결과는 수업요구도 조사에서 학습자들은 자기주도학습을 위한 다양한 학습법을 찾는 노력, 학습목표를 세우는 방법, 학습계획에 따른 실천, 학습 활동에 대한 자가 평가가 부족하다고 응답하였다. 간호학 전공 이론 교과목 학습은 블록수업으로 인하여 공부할 분량에 비해 시간이 부족하므로 다양한 교수학습형태의 중요성은 알지만 교수자 전달식 강의가 도움이 된다고 응답하였다. 이 결과를 근거로 설계한 교수자 스캐폴딩을 적용하여 성인간호학 교과목 운영 후 학습태도, 비판적 사고성향, 자기주도 학습능력의 점수는 모두 사전에 비해 사후에 유의하게 증가 하였다. The purpose of this study was to identify the learning attitude, critical thinking tendency, and self - directed learning ability by applying the instructor scaffolding to promote learner s self - directed learning of nursing college students. As for the research design, investigation on educational needs was survey research, and the effect of applying instructor scaffolding was quasi-experiment by one group pre-post test design. For research target, survey on educational needs included 196 juniors and 191 seniors, while study on effect of applying scaffolding involved 123 seniors. Moreover, educational needs survey and preliminary survey were conducted in March 2016 to collect data, and a post survey was carried out in June, after applying instructor scaffolding. The collected data were processed using SPSS/WIN 21.0 program. As a result of the survey on educational needs, learners answered that efforts to find various study methods for self-directed learning, measures of establishing study goals, fulfilling study plans and self-evaluation on study activities were insufficient. As for theory courses of nursing, they answered that didactic lectures were helpful due to the block schedule; although they were aware of the importance of various teaching types, time was insufficient compared to the study load. After running adult nursing courses by applying an instructor scaffolding designed based on the result, scores of learning attitude, critical thinking tendency and self-directed learning ability all showed significant increases in the post survey compared to the pre test.

성주류화 관점에서 본 한국 ODA 사업의 실행

김양희 ( Yanghee Kim ) 한국정책학회 2017 韓國政策學會報 Vol.26 No.1

한국을 비롯한 선진공여국들이 개도국의 성 평등과 여성역량강화를 위해 여성대상 사회개발 프로젝트사업을 실행하고 있지만, 어떤 사업들은 막대한 예산 투입에도 불구하고 여성주민들의 수용도와 효과가 크지 않다는 비판이 제기되고 있다. 이 연구는 개발원조 프로젝트사업의 그러한 문제점을 한국 ODA사업의 실행 측면에서 살펴본다. 한국 ODA 프로젝트사업 집행기관들은 성주류화를 통합한 사업의 기획과 실행을 주저하고 있다. 한국 ODA 사업이 젠더에 대한 관심과 이해가 부족한 채 `몰성적(gender-blind)`으로 실시되고 있는 것은 첫째, 주요 여성정책이자 전략인 성주류화에 대한 인식과 관심 부족, 성주류화와 관료제와의 긴장 등에서 비롯된다. 둘째, 여성역량강화를 위해 실시되는 여성대상 교육, 캠페인, 홍보활동 등은 가시적인 사업효과는 적은 대신 인력과 수고가 많이 들어 비가시화된채 축소되기 쉽다. 셋째, 사업의 성과를 인사제도에 연동한 성과주의 인사제도는 성주류화 조치들 가운데 달성하기 손쉬운 지표들을 선호하게 만들며 성과달성에 연연하는 성과주의를 유발한다. 성주류화전략을 사업의 모든 단계에 적용한 성인지적 사업이 제대로 실행되기 위해서는 여성대상 사업의 실행을 제한하는 `보이지 않는` 구조가 바뀌어야 한다. This study reviews Korean ODA social development projects in terms of gender mainstreaming. Many donor countries, including Korea, implement social development projects for poor women in developing countries. Though they assign much budget for the results of the projects, there are many critics that women residents don`t have much benefit from those projects and have little effect on the improvement of their livelihood. In such a context, this study examines why many Korean ODA social development projects have little effectiveness for a better life for women in terms of gender mainstreaming. Many Korean ODA organizations are hesitated to plan and implement gender sensitive and integrated projects. The reasons why many Korean ODA social development projects have been implemented as `gender blind` perspectives are as follows. First, it was initiated from lack of concern for gender issues and lack of gender awareness even though gender mainstreaming has been major women policy and strategy in Korea since late 1990`s. Second, it was the results of tension between gender mainstreaming and bureaucracy in many governmental ODA organizations. Third, women targeted training, campaigns and promoting activities for women empowerment have little-visualized results, rather they need much human forces and efforts. So they would be reduced the sizes and the amounts of the projects and would become as unvisualized. Last, the performance based human management and incentive systems can be caused resultism that is preferred to achieve relatively easy outcomes and avoided the difficult and detailed results. For the success of women targeted social development projects, it should be changed from gender blind and unvisualized project implementation structure to gender sensitive structure.
