현재 농작물의 품질과 직결되는 병해충에 관하여 농작물 재배 현장에서 바로 사용할 수 있는 모바일 전용의 응용 시스템은 부족한 실정이다. 따라서 본 논문에서는 병해충 예찰 및 기본 정보에 관해서는 충실하나 즉각적인 진단 기능이 매우 부족하고 아울러 농작물 재배 현장에서 바로 사용할 수 있는 모바일 기반의 병해충 전용 시스템의 부재를 개선하기 위해서, u-Farm을 위한 모바일 기반의 농작물 재배 현장 중심형 스마트 병해충 정보검색 시스템을 설계 및 구현한다. 제안하는 시스템은 이미지의 전문 분석에 유용한 검색 라이브러리인 루씬(Lucene) 및 JSON 데이터 구조를 기반으로 농작물 재배 현장에서 병해충의 정보를 웹뿐만 아니라, 본인이 소유한 스마트 폰을 통해 실시간으로 직접 확인할 수 있는 장점이 있다. 또한, 시스템의 확장 및 재사용성을 높이기 위해 객체지향 모델링을 기반으로 설계하였으며, 농작물의 메타 정보뿐만 아니라, 메타 정보 기반의 텍스트 및 색상 등과 같은 이미지 특징 정보를 기반으로 검색이 가능하다. 본 시스템을 통해 u-Farm 실현뿐만 아니라 농업인이나 재배 현장 관리자들이 농작물 작황, 병해충 현황 파악 및 관리를 실시간으로 진행할 수 있다. There is a shortage of mobile application systems readily applicable to the field of crop cultivation in relation to diseases and insect pests directly connected to the quality of crops. Most of system have been devoted to diseases and insect pests that would offer full predictions and basic information about diseases and insect pests currently. But for lack of the instant diagnostic functions seriously and the field of crop cultivation, we design and implement a crop cultivation field-oriented smart diseases and insect pests information retrieval system based on mobile for u-Farm. The proposed system had such advantages as providing information about diseases and insect pests in the field of crop cultivation and allowing the users to check the information with their smart-phones real-time based on the Lucene, a search library useful for the specialized analysis of images, and JSON data structure. And it was designed based on object-oriented modeling to increase its expandability and reusability. It was capable of search based on such image characteristic information as colors as well as the meta-information of crops and meta-information-based texts. The system was full of great merits including the implementation of u-Farm, the real-time check, and management of crop yields and diseases and insect pests by both the farmers and cultivation field managers.

강주희(Kang, Ju-Hee),이대균(Lee, Dae-Kyun) 한국어린이문학교육학회 2021 어린이문학교육연구 Vol.22 No.3

본 연구는 만5세 학급의 놀이관찰 기록 다시보기 과정에서 특정 놀이의 발생 즉, 창발을 이끈 우연한 사건이나 경험을 ‘세렌디피티(serendipity)’라는 용어 및 개념에 비추어 세렌디피티의 구성요인을 규명하고, 이에 따른 놀이의 창발적 속성은 어떠한지 질적인 연구방법으로 살펴보는 데 목적이 있다. 연구 결과, 첫째, 세렌디피티는 ‘참신성’, ‘놀라움’, ‘에너지’, ‘스토리텔링’이라는 구성요인을 갖는 것으로 나타났다. 둘째, 이러한 세렌디피티 구성요인과 관련해 나타난 놀이의 창발적 속성으로는 ‘호기심과 독창성’, ‘민감성’, ‘융통성과 인내성’, ‘상상력’을 갖는 것으로 나타났다. 셋째, 세렌디피티 구성요인과 관련해 나타난 놀이의 창발적 속성의 의미로는 놀이에 대한 관성적 시선에서 벗어나 놀이의 본질과 의미에 대한 재해석의 지평을 넓혀 주는 ‘낯설게 하기 또는 보기(defamilarization)’의 의미와, 놀이의 다양성과 복잡성을 기반으로 한 놀이의 창발을 이해하는 단초를 제공하며 귀 기울임의 교육을 시사하는 ‘내부 작용(intra-activity)의 교육과 놀이의 다양성’으로서의 의미를, 집단 지성을 통한 함께 만들어가는 놀이중심의 교육의 가치를 발견할 수 있는 ‘상호작용과 협력을 통한 노력의 함수값’의 의미를, 교사와 유아를 감응시켜 세렌디피티를 경험하도록 만들어 주는 ‘영감을 주는 감응의 사건’으로서의 의미를 갖는 것으로 나타났다. 본 연구는 유연하게 전개되어 나가는 놀이의 창발적 속성과 의미를 재조명해 볼 수 있는 연구가 될 수 있음을 시사한다. In this study, the occurrence of a specific play, that is, an accidental event or experience that led to the emergence of a play observation record in a 5-year-old class, in the light of the term and concept of ‘serendipity’, was identified, and the constituent factors of serendipity were investigated. The purpose of this study was to examine the emergent properties of the following play through a qualitative research method. As a result of this study, first, it was found that serendipity has the following components: ‘novelty’, ‘surprise’, ‘energy’, and ‘storytelling’. Second, the emergent properties of play that appeared in relation to these serendipity components were found to have ‘curiosity and originality’, ‘sensitivity’, ‘flexibility and patience’, and ‘imagination’. Third, as the meaning of the emergent attribute of play in relation to the serendipity component, it is the meaning of ‘defamiliarization’, which breaks away from the inertial view of play and broadens the horizon of reinterpretation of the essence and meaning of play. Additionally, it provides a clue to understand the emergence of play based on the diversity and complexity of play, and the meaning as ‘education of intra-activity and diversity of play’, which suggests an education of attentiveness, The meaning of ‘a function value of effort through interaction and cooperation’ that can discover the value of play-oriented education was created together by appearing to have a meaning. The findings suggests that it can be a study that can re-examine the emergent properties and meanings of play that is developed in a flexible manner.

옵아트 작품을 응용한 헤어 아트 디자인 연구

강주희(Ju Hee Kang) 한국디자인문화학회 2013 한국디자인문화학회지 Vol.19 No.2

옵아트는 망막의 예술로 단순히 미술의 영역을 뛰어 넘어 다양한 방면으로 활용되어 여러 가지 디자인으로 사용되고 있다. 헤어아트는 감각과 사상을 전달하는 예술매체의 수단으로, 예술의 개념과 헤어의 기능성을 결합시킨 새로운 표현양식의 작품이다. 따라서 옵아트의 시지각 착시를 이용한 망막의 예술을 헤어아트로 제작하여 옵아트의 사상과 표현방식을 유형의 예술로표현할 수 있다. 따라서 본 연구는 강렬한 흑색무늬의 파동치는 선들과 다양한 형태의 변조로 망막의 강한 자극을 선보인옵아트 작가 Bridget Riley와 옵아트의 창시자이며 큐비즘의 영향으로 평면을 입체화하는 기하학적 추상주의를 발전시킨 Victor Vasarely의 작품을 모티브로 이용하여 각 작품의 특징을 실제 모델의 헤어와 인조피스를 이용하여 헤어아트로 제작하고 옵아트적인 의상과 모델의 자세연출로 완성하여 옵아트와 헤어아트의 접목으로 새로운 디자인을 모색 하는데 목적이 있다. 이를 위한 연구방법으로 우선 일반적 옵아트 이론에 대한 선행논문을 바탕으로 대표작가 Bridget Riley, Victor Vasarely, Josef Alers의 옵아트 접근 방법의 특징을 이해하고 대표 작품을 분석한 후 옵아트의 착시를 응용한 작품 제작에 관한 문헌자료와 다양한 인쇄 매체, 제작된 상품을 바탕으로 의상, 장신구, 그밖에 소품에 나타난 옵아트로 각각 정리해 망막의 착시를 이용한 디자인의 다양한 응용을 확인했다. 이를 바탕으로 헤어아트로 제작하기 용이한 시지각 착시의 과감성을 보인 Bridget Riley의 3작품(Kiss, Arrest2, Fragment 2/10)과 Victor Vasarely의 1작품(Meandres Belle-Isle)을 모티브로 모델의 실제 헤어와 인조피스를 이용하여 헤어아트를 제작하였다. 각 결과물을 통하여 얻은 결론은 다음과 같다. Kiss를 응용한 작품은 흑색무늬의 강렬한 대비로 오는 시지각 착시를 표현하기에 적합한 모티브였고, Arrest2와 Fragment 2/10는 선들의 파동치는 형태로 입체적 착시를 모발에 연출하기 적합했다. Meandres Belle-Isle는 평면의 것에서 입체적인 형태로의 착시를 헤어와 인조피스로 제작해 헤어디자인의 형태적 착시로 살리는데 적합했다. 현재 시지각 착시를 응용한 헤어아트의 제작은 아직미흡하나 다양한 소재로 응용되고 있는 옵아트의 연구를 통해 각 작품의 특징을 모티브로 제작된 헤어아트의 본 연구를 통하여 활발한 작품 활동을 예측해본다. Op art has been applied in a variety of designs in diverse kinds of fields beyond the simple scope of art as the retinal art. Hair art is a new kind of expressive art combining the concepts of art and the functionality of hair as the tool of artistic media delivering senses and thoughts. Accordingly, the retinal art using the visual and perceptual optical illusion of the optical art is created in the hair art and so expresses the thoughts and expressive methods of optical art in tangible art. This paper took the motive from the works by Victor Vasarely who developed the geometric abstractionism making a plane the dimensional object by the influence from Cubism as the originator of optical art, and the optical artist Bridget Riley presenting the strong stimulation of a retina in various kinds of shapes and waving lines of loud black patterns. With such motives, this paper aimed to express the features of each works in the hair art using a hair of a model and the false hair pieces, complete the hair art with the optical art costumes and posturees of models and so find out the new designs by combining optical art and hair art. To this end, this paper investigated the approaches and features of optical art by the representative artists Bridget Riley, Victor Vasarely and Josef Alers based on the existing theses on the optical art theories and analyzed the representative works by those artists. Next, this paper verified a variety of application by the designs using the retinal illusion by summarizing the optical arts observed in costumes, accessories and other articles based on the literature on the works applying the illusion of optical art, a variety of printed media and created goods. On the basis of the analysis, the hair art was created using actual hair of a model and false pieces by taking the motives from three works by Bridget Riley(Kiss, Arrest2, Fragment 2/10) and one works by Victor Vasarely(Meandres Belle-Isle) presenting the resolution of visual and perceptual illusion which were easy to create hair. The analysis and creation results are presented below. The works applying the works Kiss was the proper motive for expressing the visual and perceptual illusion from the loud contrast of black patterns. Arrest2 and Fragment 2/10 were suitable for expressing the dimensional illusion from waving lines on hair. Meandres Belle-Isle was also suitable for creating the formative illusion of hair design by producing the illusion from flat form to dimensional form using hair and false pieces. Although the hair art using visual and perceptual illusion is not complete at present, the creative works will be activated by this research on the hair art taking the motives from the features of each optical art works applied with a variety of materials.

본 연구는 e-Learning 환경에서 동영상 강의를 들을 때, 강의 조작행위를 최소화해 학습자의 주의집중을 향상시키는 방안을 고안하는 것을 목적으로 진행했다. 학습자의 강의 조작행위는 주의집중을 방해하는 요소라고 간주했다. 강의 학습자의 고개 움직임에 따라 동영상의 속도를 변화시켜 학습자가 강의 조작을 하지 않도록 돕는 기능을 연구했다. 학습자의 고개의 상하 움직임을 분석해, 고개를 들고 숙이는 이유와 필기의 관계를 관찰했다. 필기를 하지 않는 고개 움직임의 최소 시간을 측정했고, 강의 속도 자동조절 기능 실험에 적용 했다. 이 시간을 강의 속도 자동조절 기능에 적용함으로써 짧은 고개 움직임에 기능이 반응하는 것을 방지할 수 있었다. 실험1 결과 학습자들의 고갯짓 중 2초 이내의 경우 필기와 관련이 없었으며, 2초에서 5초 사이는 짧은 필기, 5초 이상은 긴 필기를 하는 것으로 관찰되었다. 이에 따라 강의 속도 자동조절 방법은 고개가 내려간 후 2초간의 시간차를 두고 시행하는 것으로 실험2를 진행했는데, 필기를 방해하는 조작 횟수가 1/4로 줄어든 것을 확인할 수 있었다. 따라서 강의 속도 자동조절 방법은 필기에 도움을 줌으로써 주의집중 향상에 긍정적인 영향을 주는 것으로 결론지을 수 있었다. This study is to develop learner"s attention to help taking notes by minimizing function control and adjusting play speed with learner’s habit during studying e-Learning. we analyze learner’s head nodding and divide head shaking into two situation. One is nodding for note-taking and the others are nodding for nothing. We study on the relationship nodding with note-taking. Counted nodding time shows us minimum time for ignoring nod of head. This nodding time is applied to a function of auto-controlling of media speed for e-Learner. So we can prevent that the function unnecessarily changes a speed of e-learning lecture. As a result of the case 1, under 2 seconds of learner"s noding time is meaningless. Between 2 seconds to 5 seconds of learner"s noding time is note-taking for short words. Over 5seconds of learner"s noding time is note-taking for long sentences. We apply the auto-controlling of media speed to the case 2. In the case 2, learner" the number of function control and adjusting play speed decreased to 1/4. As a result of the study, it showed that the function of auto-controlling of media speed has a positive influence on note-taking for attention improvements.

Purpose: In Korea, market size of social commerce has been increased steadily and highly, but profits of social commerce companies have been decreased because of excessive marketing cost. To overcome this stagnant market environment, new marketing strategy that could attract customers and make customers continue to use social commerce is required instead of cost consuming marketing strategy. The purpose of this study is to investigate the relationship among characteristics of social commerce - that is, economic value and information quality - usefulness, enjoyment, satisfaction and repurchase intention by applying motivation theory to the area of social commerce. Design/Methodology/Approach: Previous researches have been studied by applying Expectation-Confirmation Model (ECM), Theory of Planned Behavior (TPB), Technology Acceptance Model (TAM) and Stimulus-Organism-Response (S-O-R) Model, although there are many studies related with customer acceptance model in the field of e-commerce. However, there is not so many studies in applying motivation theory. So this study adopts new approach to examine why customers use social commerce based on motivation theory. Thus, this study adopts economic value and information quality as antecedents, and then customers will perceive extrinsic and intrinsic motivation; usefulness is extrinsic and enjoyment is intrinsic, and adopts satisfaction and repurchase intention as a dependent variable. The data of questionnaire were collected from customers who have experience to buy something in social commerce. 228 questionnaires as data unit of individual level were collected using random sampling. Findings: This study proved empirically that the relationship between antecedents and motivation factors has a positive influence, and motivation factors also have a positive influence on repurchase intention through satisfaction. This study provides the managers an insight that social commerce companies should pay more attention to improve customer satisfaction in order to increase higher performance in repurchase intention of social commerce.
