  • This study critically appraised the accumulated articles based on the critical science perspective on Korea's home economics education. The 55 articles published from 1993 to 2011 were identified and placed into three categories: Critical science paradigm, practical problem-focused curriculum, and systems of action. The common result across categories was that some authors did not fully understand the concepts of practice, a practical problem-focused curriculum, the practical reasoning process, and the systems of action. A positive outcome of including a critical science perspective in the Korean national curriculum will be seen when systems supporting this perspective, such as those providing more specific information on a critical science perspective and the relevant textbook accreditation standards, are available. We present a proposal based on considerations of a national curriculum, teacher education, relevant philosophical perspectives, and classroom practice.

  • The aim of this study is to find the model that best explains members' continued use intention in virtual communities by comparing technical and social perspectives applied in IS context. With the eight major variables identified from prior studies, four alternative models were formulated:1) A base model from Information Systems (IS) continuance perspective, 2) IS continuance model with technology-acceptance perspective, 3) IS continuance model with social-capital perspective, and 4) IS continuance model with socio-technical combined perspective. The adequacies of these four models with different perspective highlighted were tested using survey data collected from virtual community users in Korea. The findings indicated that the IS continuance model and social-capital perspective is the most efficient model that best explains the members' continued use intention in virtual communities.

  • Digital refocusing and perspective change are the most expected applications of light field (LF) images. As LF image has a large amount of data, its compression is very essential. The fidelity of LF image after compression needs to be evaluated differently depending on a specific application such as perspective change or refocusing. In this paper, we investigate the fidelity of images after perspective change and refocusing. Several state-of-the-art objective quality metrics are compared. Our experiment shows that IWPSNR is the most reliable metric for both perspective and focus changes, but it does not outperform the popular metrics such as PSNR and SSIM.

  • In this paper, we propose a method for correction of perspective distortion on a taken image. An image taken by a camera is caused perspective distortion depending on the direction of the camera when objects are projected onto the image. The proposed method in this paper is to obtain the normal vector of the plane through the depth information using a depth camera and calculate the direction of the camera based on this normal vector. Then the method corrects the perspective distortion to the view taken from the front side by performing a rotation transformation on the image according to the direction of the camera. Through the proposed method, it is possible to increase the processing speed than the conventional method such as correction of perspective distortion based on color information.

  • When the planar area is captured by the depth camera, the shape of the plane in the captured image has perspective projection distortion according to the position of the camera. We can correct the distorted image by the depth information in the plane in the captured area. Previous depth information based perspective distortion correction methods fail to satisfy the real-time property due to a large amount of computation. In this paper, we propose the method of applying the conversion table selectively by measuring the motion of the plane and performing the correction process by parallel processing for correcting perspective projection distortion. By appling the proposed method, the system for correcting perspective projection distortion correct the distorted image, whose resolution is 640x480, as 22.52ms per frame, so the proposed system satisfies the real-time property.

  • Contemporary Chinese "micro-perspective" painting is an artistic phenomenon that we cannot ignore. It is the young artists who focus on themselves and their communities, record their stories and emotions in their life fragments into the coming history, and diary paintings as "micro-perspective" paintings allow "marginal people" to find their place. Based on the analysis of the aesthetic form and aesthetic characteristics of Chinese contemporary art, this paper explores the three aesthetic dimensions and their inherent aesthetic value, and explains its significance from the perspective of "micro-view" aesthetics. In the contemporary context, "micro-perspective" painting has become a unique cultural phenomenon, a consciousness situation. However, this phenomenon has a very unique artistic value and cultural value for the youth art group and even the formation of aesthetic culture and zeitgeist in China's current society.

  • This study focuses on developing a theoretical framework for evaluating Operational Performance of the Marine Forest Creation project on a balanced and comprehensive perspective by using BSC, AHP, and IPA. Also, the purpose of this study is empirically to analyze operational performance of the project and to suggest the future improvement plan. For this purpose, We will first determine the critical success factors(CSF) and key performance indicators(KPI) required for evaluating the performance of the Marine Forest Creation project from the four perspectives of BSC. And, After determining the weight for each of CSF, KPI, and four perspectives of BSC by using AHP, we will measure the project performance. We will also conduct IPA analysis to propose the direction of improvement of the Marine Forest Creation project. The results of this study are as follows. First, this study has drawn 8 critical success factors and 16 key performance indicators for four BSC perspectives based on the theoretical considerations and expert interview survey. Second, as a result of deriving relative importance of BSC perspectives using AHP, customer perspective was the highest, followed by financial perspective, learning and growth perspective, and internal process perspective. Third, as the results of analyzing the importance and performance of BSC perspectives using IPA, customer perspective was the maintenance reinforcement category, financial perspective was the key improvement category, internal process perspective and learning and growth perspective were gradual improvement category. This study has a great academic significance in terms of BSC first tried to evaluate the performance of the Marine Forest Creation project. The results of this study are expected to lead to various discussions for a balanced and comprehensive verification of Marine Forest Creation project performance.

  • Objectives : This paper aims to study the I-Ching perspective in Shanghansuyuanji. Methods : Key words associated with I-Ching was searched in Shanghansuyuanji and analyzed its meaning and categorized thematically. Results & Conclusions : 1. Qianhuang symbolized Shaoyang, The Power of the Great hexagrams, Jueyin Peace hexagrams, Taiyin Gen Earth, Yangming Kun Earth, Shaoyin Return hexagrams, but didn't symbolize Taiyang, making it not uniform. 2. Qianhuang explained physiology focusing the change of YangQi with I-Ching perspective. This is possible because Shanghanlun thought that much of YangQi and I-Ching set a high value on Yang. 3. Qianhuang explained pathology such as insomnia, epigastric fullness, splenic constipation syndrome, Taiyinbing syndrome, somnolence, thirst, YinYang exchange with I-Ching perspective, it is meaningful because it enriches medical YinYanglun. 4. Qianhuang explained prescriptions such as Daqinglongtang, Zhenwutang, Shizaotang, Fuzixiexintang, Dachaihutang, Baihutang, a comparison between Daqinglongtang and Xiaoqinglongtang with I-Ching perspective. This is helpful to grasp the image of prescriptions. 5. Qianhuang explained nature of drugs such as Guizhi, Fuling, Fuzi, Qiandan, Rougui with I-Ching perspective, and it combines well with the features of I-Ching with drugs efficacy. 6. Qianhuang explained diseases of the six Meridians curing time with I-Ching perspective. This shows diseases of the six Meridians recover when Corresponding Qi is vigorous or Conflict Qi appears, and it is persuasive. For reasons mentioned above; Shanghansuyuanji is meaningful as Shanghanlun commentary.

  • In the 7th curriculum revision, Home Economics and Technology are combined into one subject, Practical Arts(Technology Home Economic), from 5th to 10th grades. The purpose of this study was to ewamine what perspectives home economics teachers and technology teachers have on curriculum. A questionnaire survey was carried out to the 297 middle school home economics teachers and technology teachers across the nation, to find out the differences of their perspectives on curriculum by independent variables. The findings of this study were as follows: 1) Both groups of home economics teachers and technology teachers supported interpretive, emancipators, and technical perspective on curriculum in the order named. 2) Teachers who have teaching experience of 21 years or more showed higher orientation toward technical perspective than those who have teaching experience of 10 years or less in assumptions on society, educational goal, Knowledge, and teaching-loaming method. 3) Public school teachers showed stronger orientation toward technical perspective in assumptions on teaching-learning method, and toward emancipatory perspective in assumptions on society. 4) Teachers who majored in or took charge of Technology generally had strong orientation toward technical perspective, whereas those who majored in or took charge of Home Economics oriented more toward interpretive or emancipatory than technical perspective.
