  • Left atrial myxoma constitutes the most significant cardiac tumors, which occupies 30 to 50% of the total in most pathological series with the age range from 3 to 83 years, mostly between the age of 30 to 60 years. Over 90% of myxomas occur in the atria, with 3 to 4 times as many occurring in the left as in the right. They may cause severe and progressive disease mimicking mitral valvular disease with non-specific general symptoms. Recent attentions were focussed in the clinical features along with various diagnostic techniques including angiocardiography, echocardiography and cross-sectional sector scanning echocardiography, and definitive treatment with surgical removal under direct vision using cardiopulmonary bypass. There are several reports on the atrial myxomas removed from various cardiac chambers in Korea, and we report another typical case of left atrial myxoma of 6.8 x 3.8 x 1.7 cm3 attached to the upper margin of fossa ovalis with a short pedicle, also with calcification at it`s distal free end. 29 year old young mother complaining of mild fever, vaginal spotting, numbness of left upper and lower extremities, nocturnal attack of dyspnea and palpitation for 2 months was diagnosed as large left atrial myxoma with the aid of angiocardiography and echocardiography. Trans-right-atrial, transseptal surgical removal of the tumor was successfully performed under the cardiopulmonary bypass for 22 minutes on 24th of July 1980. Postoperative hospital course was uneventful and discharged from hospital on the 12th POD with complete recover from the previous symptoms and signs.

  • There is substantial evidence from earlier researches that older adults have difficult seeing under low illumination and at night, even in the absence of ocular diseases. During human aging, there is a rampant decrease in rod/cone-meditated adaptation which is caused by delayed rhodopsin regeneration and pigment depletion. This calls for a need to develop appropriate visual gadgets to effectively aid the aging generation. Our research culminates its approach from Pattanaik's model by making extensions to temporal visual filtering, thereby simulating a reduction of visual response which comes with age. Our filtering model paves way and lays a foundation for future research to develop a more effective adaptation model that may be further used in developing visual content adaptation aids and guidelines in MPEG 21 environment. We demonstrate our visual model using a High Dynamic Range image and the experiment results are in conversant with the psychophysical data from previous vision researches.

  • The first local exchange trading system(LETS), established in Comox Valley in Canada, aimed at facilitating the regional economy. However, in Korea, LETS was adopted to encourage mutual aid and promote community spirit among residents. This study examines the feasibility of LETS as a revitalization initiative for Pumasi and suggests a number of policies that can be implemented to support the project. The findings are as follows: First, the LETS credit system was found to complement social capital initiatives among Pumasi participants in the early stages of the Pumasi project. Second, combining LETS and Pumasi initiatives was found to consolidate community spirit and encourage a cooperative way of life among participants due to the fact that LETS enlarges the scope of local residents' participation and diversifies the services being exchanged. A number of policy suggestions are made for combining LETS with Pumasi. First, the project must define a vision of its long-term purpose and outcomes. Second, local residents should be employed as assistants to facilitate the project. Third, Pumasi participants should ensure that childcare exchange services are of the highest quality by providing an educational program on parenting. Fourth, the project manager's employment conditions and working environments must be guaranteed.

  • This paper presents the development of the remotely operated decontamination systems for use in a highly radioactive zone of the DUPIC Fuel Development facility of the Irradiated Material Examination Facility at the Korea Atomic Energy Research Institute. The remotely operated decontamination systems were designed to completely eliminate human interaction with hazardous radioactive contaminants. These decontamination systems are mainly classified into three systems depending on the task environment - a fabrication equipment decontamination system, a hot-cell floor decontamination system, and an isolation room floor decontamination system. A decontamination system for contaminated fabrication equipment utilizes dry ice pellet blasting method to decontaminate contaminated surface of the equipment. The decontamination systems for the hot-cell floor and isolation room floor employ a vacuum cleaning method to decontaminate the contaminated floor and collect loose dry spent nuclear fuel debris and other radioactive waste placed on the floor. The human operator from the out-of-cell performs a series of decontamination tasks remotely by manipulating decontamination systems located in-cell via a handcontroller with the aid of vision feedback information. The environmental, functional and mechanical design considerations, control system and capabilities of the remotely operated decontamination systems at a high radioactive environment are also described.

  • In this paper, we present the R&D status of ETRI's Trusted Reality (TR) project and its core technologies. ETRI's TR project focuses on the next-generation paradigm of smart phones, ETRI-TR Smart Glasses, which aims to provide the same features as those of smart phones without the involvement of any handheld device. Furthermore, they are characterized by additional features enabled by trustworthy VR/AR/MR/XR, such as privacy masking/unmasking, distributed structure of thin-client computing/networking among TR-Glasses, TR-LocalEdge, and TR-RemoteEdge, with novel see-through eyes-direct communication between IoT real/virtual objects and human eyes. Based on these core technologies of the ETRI's TR project, the human-held ETRI-TR Smart Glasses is expected to aid in the realization of XR vision with particularly more XR's safe_privacy on social life in the near future.

  • Both in Korea and internationally, many know and appreciate Daesoon Jinrihoe for its social work in the three main areas of education, social welfare and health care, and charity aid. The article surveys Daesoon Jinrihoe's activities in these three areas and proposes a comparison with the charitable and ecological work performed by the Taiwanese Buddhist charity (and new religious movement) Tzu Chi, the peace activities of Soka Gakkai, and the projects developed in Bhutan to implement the policy of Gross National Happiness. Tzu Chi is mostly known for its massive recycling activities, but in fact its view of charity and ecology is based on a specific Buddhist theology. Soka Gakkai's vision of peace relates to its interpretation of Nichiren Buddhism. Gross National Happiness in Bhutan is a project promoted by the government, but scholars who have studied it have concluded that it is deeply rooted in Drukpa Kagyu, the dominant school in Bhutanese Buddhism. Similarities are noted, as well as differences with the Western Christian and post-Christian approach to charity, which is largely based on an affirmation of the self. Daesoon Jinrihoe's social work shares with the Buddhist cases studied in the article the idea that the self may deceive (self-deception) but appears to be inspired by the unique principle of Sangsaeng, and by the idea that the root causes of social problems are grievances accumulated through thousands of years and in need of being resolved.

  • This study explores the organic form generation method, which reflects the evolving biomimetic approaches converging in fashion technology and considers the characteristics of the organic relationship between the body and the clothing to be represented in contemporary fashion. A literature review on biomimetic architecture and design-related theory and a case study on biomimetic fashion were both conducted. Images, articles, and data related to biomimicry fashion and clothing, including the increase in virtual fashion cases around 2020, were analyzed based on the literature review. Biomimicry was used to derive interdisciplinary similarities in the organic morphogenesis principle, and the result was categorized as a network system, folds and unfolds, pneumatic structures, auxetic growth, and membranes. The biomimetic fashion characteristics, including externalization of the body's interior, expansion of the body structure and silhouette, body protection, independence from the body, and post-human expression through virtualization, were analyzed. Morphogenetic processes performed through biomimetic vision are expected to aid in generating research on the possibility of mass production or popularization in the future through various experimental technical studies.
