Technology developers in academia tend to be short of professional knowledge and recognition of technology transfer strategies. It is even severe in Korea where the concept of employee’s invention has just started to effect in academia. Wasteful contract negotiation disputes cannot only be painful but also can hamper better invention. The main purpose of this paper is to design guidelines for an optimal contract strategy for technology transfer from the perspective of the technology developer in academia, the intermediary and the receiver. Applying conjoint analysis, this study shows not only the relative importance of the attributes related to the technology transfer contract but also the most important conditions of the contract. It is expected that this study may improve the efficiency of technology transfer activities in academia in Korea.

Recommender system recommends the items expected to be purchased by a customer in the future according to his or her previous purchase behaviors. It has been served as a tool for realizing one-to-one personalization for an e-commerce service company. Traditional recommender systems, especially the recommender systems based on collaborative filtering (CF), which is the most popular recommendation algorithm in both academy and industry, are designed to generate the items list for recommendation by using ‘overall rating’ – a single criterion. However, it has critical limitations in understanding the customers’ preferences in detail. Recently, to mitigate these limitations, some leading e-commerce companies have begun to get feedback from their customers in a form of ‘multicritera ratings’. Multicriteria ratings enable the companies to understand their customers’ preferences from the multidimensional viewpoints. Moreover, it is easy to handle and analyze the multidimensional ratings because they are quantitative. But, the recommendation using multicritera ratings also has limitation that it may omit detail information on a user’s preference because it only considers three-to-five predetermined criteria in most cases. Under this background, this study proposes a novel hybrid recommendation system, which selectively uses the results from ‘traditional CF’ and ‘CF using multicriteria ratings’. Our proposed system is based on the premise that some people have holistic preference scheme, whereas others have composite preference scheme. Thus, our system is designed to use traditional CF using overall rating for the users with holistic preference, and to use CF using multicriteria ratings for the users with composite preference. To validate the usefulness of the proposed system, we applied it to a real-world dataset regarding the recommendation for POI (point-of-interests). Providing personalized POI recommendation is getting more attentions as the popularity of the location-based services such as Yelp and Foursquare increases. The dataset was collected from university students via a Web-based online survey system. Using the survey system, we collected the overall ratings as well as the ratings for each criterion for 48 POIs that are located near K university in Seoul, South Korea. The criteria include ‘food or taste’, ‘price’ and ‘service or mood’. As a result, we obtain 2,878 valid ratings from 112 users. Among 48 items, 38 items (80%) are used as training dataset, and the remaining 10 items (20%) are used as validation dataset. To examine the effectiveness of the proposed system (i.e. hybrid selective model), we compared its performance to the performances of two comparison models – the traditional CF and the CF with multicriteria ratings. The performances of recommender systems were evaluated by using two metrics - average MAE(mean absolute error) and precision-in-top-N. Precision-in-top-N represents the percentage of truly high overall ratings among those that the model predicted would be the N most relevant items for each user. The experimental system was developed using Microsoft Visual Basic for Applications (VBA). The experimental results showed that our proposed system (avg. MAE = 0.584) outperformed traditional CF (avg. MAE = 0.591) as well as multicriteria CF (avg. AVE = 0.608). We also found that multicriteria CF showed worse performance compared to traditional CF in our data set, which is contradictory to the results in the most previous studies. This result supports the premise of our study that people have two different types of preference schemes – holistic and composite. Besides MAE, the proposed system outperformed all the comparison models in precision-in-top-3, precision-in-top-5, and precision-in-top-7. The results from the paired samples t-test presented that our proposed system outperformed traditional CF with 10% statistical significance level, and multicriteria CF with 1% statistical significance l

This study explores the purpose and principle of drama/theatre national curriculum formation which is newly included into national curriculum. The revised 2015 national curriculum is different from the past one in terms of competency-based curriculum. The competency-based curriculum emphasizes creative integration among subjects, aesthetic sensitivity and sensibility to resolve the challenge and problems. Therefore, the purpose of theatre/drama national curriculum is not to raise drama/theatre professionals but to improve students`` key competency which is provided in the entire national curriculum. And, the 2015 revised national curriculum pursued a creative and integrated leader who owns aesthetic sensibility and communicative sill as the key competency. However, the subject, drama/theatre which is included into 2015 revised national curriculum for the first time has little study upon curriculum theory and drama/theatre as a subject. Thus, the newly devised drama/theatre curriculum is not systematic. The theatre curriculum is divided into expression, experience, appreciation, cultural life and suggest process-centered curriculum and assessment pitfalls to complement professional-centered curriculum. Yet, the current theatre/drama curriculum is likely to bring about confusion due to its incompatible aims. Specifically, the terms used in target standard of drama/theatre subject are not conceptually agreed so that they will result in confusion. Besides, another confusion, whether theatre curriculum deals with education in theatre/drama or education through theatre also needs to be discussed. Nevertheless, the drama/theatre curriculum should reflect ``competencybased curriculum`` purpose because the subject ``theatre`` is dealt with not as a selective curriculum for professionals but as a comprehensive one. It should be based upon how to raise ``a creative and integrated leader``. Under this purpose, the theatre/drama should be organically integrated into curriculum. Furthermore, target standard and contents of the subject should be embodied according to this ``key competency``. In order to respond to the rapid change of national curriculum, theatre/drama curriculum and theatre/drama as a subject should be studied. To establish drama/theatre as a subject in the national curriculum, the characteristics, purpose, content, target standard and the meaning of enactment should be explained. In addition, the agreed concepts and terms should be determined. It is not yet mature for the current drama/theatre curriculum to meet the entire national curriculum which requires the cultivation of ``creative and integrated leaders``. More researches and studies are required on this matter.

이 연구는 코로나 팬데믹 시기, 2021년과 2022년 두 해에 걸쳐 진행된 온라인 수업과 온라인-오프라인 병행 초등학생 대상 문화예술교육 사례의 주요 의미를 정리하고 그 과정을 소개하는 내용이다. 연구의 목적은 비대면 교육 환경 속에서 실행한 온라인, 온라인-오프라인 병행 내러티브 기반 문화예술교육이 학생들에게 정서적 안정감을 제공하고, 소통의 힘을 중심으로 사회적 자아와 시민의식을 형성하는 데 어떤 역할을 하는지, 그 과정의 의미를 탐구하는 것이다. 연구방법은 실행적 사례연구로, 지역사회의 이야기를 소재로 내러티브 기반 문화예술교육과정을 기획하여 실행하고, 교육과정 기획 및 실행을 담당한 강사들의 심층 인터뷰와 학생, 학부모의 경험을 통해 수집된 자료를 바탕으로 문화예술교육이 비대면 상황에서도 학습자에게 미친 교육적 효과를 분석하였다. 연구 결과 내러티브 기반의 문화예술교육은 학생들에게 사회적 자아와 협력을 통한 시민의식을 형성하는 데 기여하였으며, 다양한 예술 활동을 통해 정서적 안정을 제공하고 상호 소통의 기회를 확대하였다. 또한, 학습자들이 상징적 소재를 통해 자신의 이야기를 창조하고 표현함으로써, 팬데믹 상황 속에서도 정서적 안정, 자기표현과 소통, 관계 형성의 필요성을 충족할 수 있었음을 확인하였다. 본 연구는 향후 사회적 위기 상황에서도 지속 가능한 문화예술교육의 모델을 제시하고, 예술교육의 확대 가능성을 시사한다. This study examines the significance and processes of narrative-based cultural arts education conducted for elementary school students during the COVID-19 pandemic in 2021 and 2022. The programs, delivered through online and hybrid online-offline formats, aimed to provide emotional stability and foster social identity and civic awareness in a non-face-to-face educational environment. Using an action-oriented case study method, the study implemented a curriculum centered on local community stories. Data were collected through in-depth interviews with instructors and the experiences of students and parents. Analysis revealed that narrative-based cultural arts education contributed to students' emotional stability, communication skills, and collaborative social awareness. Through artistic activities such as storytelling, students expressed their ideas, created personal narratives using symbolic materials, and strengthened relationships despite pandemic-induced isolation. The programs demonstrated that cultural arts education fulfills essential needs for self-expression and interpersonal connection while fostering creativity and resilience in crisis situations. This study highlights the potential for sustainable cultural arts education models during societal disruptions, offering a framework for expanding arts education in diverse educational settings.

역사교육에서 젠더사의 의의

具珉廷(Ku Min-Jeong) 歷史敎育硏究會 2009 역사교육 Vol.112 No.-

One of the characteristics of post-modern society is to compose the by-self selection and mixture among the various element of identity rather than doing it by authority or repression. In order to comply with these social changes and for the education of history which might lead the changes, I suggest gender history. The gender identity, which is a very important element that affects the formation of self-identity, has almost never been considered in history education so far. With the influence of feminism, we began to recognize that the awareness of gender influences on all aspects of human life which comes with various metamorphosis process on time and space up to now. The results of that awareness are verified in the history of woman and the history of gender. Although the research of the women’s history for the confirmation of women's subjective identity enabled the expansion of history perception via the research of women’s own experience and socioeconomic status, it did not answer the question of why women’s experience and discrimination went that long. In the mean time, under the influence of postmodernism, we became to reach the recognition that human identity is being composed by influence of structured gender awareness. In other words, the problem of gender is not merely women's own but participates in all the aspects of human life as discoursed structure. Joan W. Scott, the pioneer of the gender history, showed that the subject is being composed by both structure and subjective will. For history education, if we sort out the contents on her research, there are the gender as the subject category and the gender as the analysis method. The former which refers to gender, includes genders’ experience, system, ideology, power structure, etc. The latter regards the gender as an analysis category when it comes to the interpretation of history. It includes the significance of the change and progression as well as the gender analysis of revolutions and wars. In history education which includes gender history as a curriculum contents, for the construction of gender identity, there is a structural characteristic in which gender's experience and consciousness are historically changed with its diversity. Students would recognize his/her-self as an object of change by discourses and as a positive subject agent. History education with the gender history is educational in that it issues not only the gender’s experience but questions about the elements which produce discrepancy between genders’ experiences. As a result, students shall have chance of self-reflection. In this work, I suggested the necessity of history education for the consciousness of gender identity. From now on, the researches which verifies the relationship between historical perception and growth to an affirmative self-identity of student must be continued in line with development of teaching materials and practice in the class.

Although the iterative closest point (ICP) algorithm has been widely used to align two point clouds, ICP tends to fail when the initial orientation of the two point clouds are significantly different. In this paper, when two triangular meshes A and B have significantly different initial orientations, we present an algorithm to align them. After obtaining weighted centroids for meshes A and B, respectively, vertices that are likely to correspond to each other between meshes are set as feature points using the distance from the centroid to the vertices. After rotating mesh B so that the feature points of A and B to be close each other, RMSD (root mean square deviation) is measured for the vertices of A and B. Aligned meshes are obtained by repeating the same process while changing the feature points until the RMSD is less than the reference value. Through experiments, we show that the proposed algorithm aligns the mesh even when the ICP and Go-ICP algorithms fail.

The objective of this study was to evaluate the effect of different dietary corn levels in Total Mixed Rations (TMR) on growth and meat quality of castrated Korean black goats. For feeding trials, thirty-two castrated Korean black goats with similar age (average of 3 months) and body weight (average of 15.9 kg) were divided into the following four treatment groups: commercial feed (control), TMR containing 15% of corn (T1), TMR containing 25% of corn (T2), and TMR containing 35% of corn (T3) in a randomized complete block design. Final body weight was the highest in T2 (58.9 kg), followed by that in control group (53.1 kg). Average daily gain (ADG) and total dry matter intake (TDMI) were also the highest in T2 (100.2 g and 1,346 g, respectively). However, feed conversion ratio (13.4) was the lowest in T2. Carcass weight and dressing percentage in T2 and T3 were higher than those in the control. For meat quality characteristics, crude fat content was the highest in T2 (6.54%). Cooking loss (15.2%) was the lowest in the control. However, the control had the highest flavor value (5.3%). Oleic acid (C18:l) and palmitic acid (C16:0) were the highest in T2 (48.6% and 22.4%, respectively). Stearic acid (C18:0) was the highest in T1 (14.5%). Unsaturated fatty acid was the highest in the control (58.8%), followed by that in T3 (58.2%), T2 (57.8%), and T1 (54.4%). These results indicate that TMR containing 25% of corn could improve the growth performance and meat quality of castrated Korean black goats.

본 연구는 산란계에서 남은 음식물과 녹차 부산물이 산란계의 산란성적과 계란품질에 미치는 영향을 연구하였다. 공시동물은 50주령 Tetran Brown종 산란계 210수를 7처리 5반복 (반복당 6수)으로 임의 배치하였다. 시험설계는 대조구와 옥수수 곡류와 대두박을 대용한 건조된 남은음식물 10, 20, 30 및 40% 첨가구 (10% DLF, 20% DLF, 30% DLF 및 40% DLF)와 1.0%의 녹차 부산물 첨가구 (1.0% GTB)와 30% DLF와 1.0% GTB를 첨가한 혼합 첨가구를 두어 사양실험을 8주 동안 실시하였다. 산란율은 대조구에 비하여 10, 20 및 40% DLF 처리구에서 유의적으로 증가하였다 (P<0.05). 난중은 대조구에 비하여 10% DLF 처리구에서 유의적으로 감소하였다 (P<0.05). 사료 섭취량은 대조구보다 20% DLF 처리구와 30% DLF와 1.0% GTB의 혼합 첨가구에서 높게 나타났다 (P<0.05). 사료 요구율은 대조구에 비하여 10% DLF 처리구와 1.0% GTB 처리구에서 유의적으로 감소하였다 (P<0.05). 난황 콜레스테롤은 DLF 처리구와 대조구 사이에서 변화가 없었다 (P>0.05). 난황의 리놀렌산은 DLF 처리구와 1.0% GTB 첨가한 처리구에서 유의적으로 증가하였다. This study was designed to determinate the effects of dried leftover food and green tea by-product on laying hens performance and egg quality in hens. A total of 210 “Tetran Brown” layers 50-weeks of age were assigned to 7 treatments in a completely randomized design. Each treatment had five replicates per treatment with six layers per replication. Seven dietary treatments were a control diet (formula diet) and dried leftover food (DLF) mixed in 10, 20, 30 and 40% to the control diet substituting the corn grain and soybean meal, control diet containing 1.0% GTB without DLF supplementation and control diet containing 30% DLF plus 1.0% GTB supplementation. The trial period was for 8 weeks. The egg production rate of layers was significantly increased in 10, 20 and 40% DLF treatments compared to that of the control treatment (P<0.05). The egg weight was significantly decreased in 10% DLF treatment compared to that of the control (P<0.05). The feed intake of layers was higher in 20% DLF and 30% DLF plus 1.0% GTB treatment than that of the control (P<0.05). The feed conversion ratio significantly decreased in 10% DLF and control plus 1.0% GTB treatments compared to that of the control (P<0.05). The egg yolk cholesterol not varied among the DLF and control treatments (P>0.05). However, the linolenic acid content of egg yolk was significantly increased in DLF and control treatments both containing 1.0% GTB supplementation.
