This study is for the great quantity use of fly-ash. For the producing of high volume concrete from the use of fly-ash, the method of replacement between bonding agents and fine aggregate by fly-ash at the same time was used. It was used that the adiabatic temperature rise of concrete about the mass member which bad been produced by the method that was mentioned before, and the hydration heat of the core test pieces in concrete was measured. Also the core test pieces which were replaced with fly-ash was studied by the compressive strength`s comparison between standard care test pieces and core test pieces. In the case of mass test pieces, hydration heat and the time to reach the highest temperature were decreased by an increase in replaced fly-ash`s amounts of concrete. In addition, among the test pieces having the same amounts of concrete, the test pieces having more replaced amounts of fly-ash`s fine aggregate showed higher hydration heat and the increased time to reach the highest temperature. Compressive strength was also increased by hydration heat`s decrease according to fly-ash replacement. Replacement of fly-ash was more effective in high temperature environment.

Pleural complication is extremely rare among the complications of lung following transcatheter arterial chemoembolization (TACE) for hepatocellular carcinoma. We report a case of hepatopleur al fistula complicated by TACE. A 50-year-old male was admitted to the hospital because of aggravation of cough and chest pain. Fifty-five days before admission, a liver abscess had developed and treated by percutaneous drainage. A hepatocellular carcinoma had been diagnosed as a cause of liver abscess. Forty-five days before admission, TACE had been performed for the hepatocellular carcinoma. Thirty days after TACE, dry cough and right pleuritic chest pain developed. After admission, serial CT scans of thorax and abdomen showed the pleural effusion containing the lipiodol from the liver through hepatopleural fistula. Chest tube insertion with a urokinase instillation was performed for the treatment of empyema caused by hepatopleural fistula. (Korean J Med 62:278- 283, 2002)

본 연구는 몰입형 가상현실과 소셜가상현실 사용자 경험을 고찰하고, 몰입형 소셜가상현실의 아바타 특성을 도출하는데 있다. 또한 도출된 특성을 바탕으로 새로운 커뮤니케이션 환경을 위한 아바타 디자인 방향을 제시하고자 하였다. 이를 위해 학술연구정보 DB를 사용하여 국내외 학술논문 및 도서/출판물 등 문헌조사를 통한 고찰 및 분석을 진행하였다. 연구 내용과 결과는 다음과 같다. 첫째, 소셜가상현실은 공유가상환경(The Shared Virtual Environment) 이라는 특성을 가지며, 공유가상환경을 경험하는 사용자는 다른 존재와 함께 있다는 공존감(The Sense of Togetherness)을 느끼게 된다. 둘째, 몰입형 소셜가상현실과 사용자 경험의 속성을 종합적으로 분석하여 아바타 디자인의 특성을 시각적(Visual) 특성과 비-시각적(Non-Visual) 특성으로 분류하였다. 시각적(Visual) 특성에는 아바타의 개인화(Identity of Avatar), 몸동작과 얼굴표정(Gesture and Facial Expression), 아바타의 상태표현(Display of Status)이 포함되었으며, 비-시각적(Non-Visual) 특성은 촉각적 상호작용 구현(Embodiment of Tactual Interaction), 오디오(Audio) 가 도출되었다. 셋째, 도출된 아바타 디자인 특성을 고려하여 몰입형 소셜가상현실 아바타 디자인의 방향을 세가지로 제시하였다. 첫째, 인간 간 이루어지는 시각적 상호작용을 반영한 아바타 외형 디자인과 애니메이션이 구현되어야 한다. 몰입형 소셜가상현실의 상호작용에서 아바타의 자연스러운 몸동작과 얼굴표정은 사용자의 공존감과 현전감을 크게 촉진시키기 때문이다. 둘째, 다양한 채널(Channel)을 통한 상호작용 기능들을 고려해야 한다. 아바타 간 다양한 채널을 통한 상호작용은 대화 중 많은 정보와 의미를 전달하고, 가상의 아바타를 실제 살아있는 대화상대로 인식하게 한다. 셋째, 아바타와 가상환경 간 상호작용의 특성이 아바타 디자인에 반영되어야 한다. 소셜가상현실에서 한 사용자의 행동으로 환경이 변화될 경우, 그 변화를 인지한 다른 참여자는 다른 존재와 함께 있다는 공존감과 현전감을 더욱 크게 느끼게 된다. 본 연구가 몰입형 소셜가상현실을 위한 아바타 개발과 아바타를 통해 새로운 커뮤니케이션 환경을 경험하는 사용자의 만족도를 높이고 소셜가상환경의 긍정적 효과 증대를 위한 학술적 · 이론적 자료로 활용될 수 있기를 기대한다. The purpose of this study is to investigate immersive virtual reality and social virtual reality user experience and to derive the avatar characteristics of immersive social virtual reality. It also wanted to present avatar design directions for new communication environments based on its proprieties. For this purpose, a review and analysis was carried out through a literature survey, such as domestic and overseas academic papers and bookpublishes, using the Academic Research Database. Research findings and results are as follows. First, social virtual reality has the characteristic of shared virtual environment, and the user experiencing shared virtual environment feels coexistence with other existence. Second, the characteristics of avatar designs were classified into visual and non-visual characteristics by a comprehensive analysis of the characteristics of immersion social virtual reality and user experiences. Visual characteristics included personalization, body language, facial expressions, and status of avatars ; non-visual characteristics were derived from tactile interactions, and audio. Third, the direction of immersive social virtual reality avatar design is proposed in consideration of the derived avatar design characteristics. First, Avatar exterior design and animation should be implemented reflecting visual interactions between humans. This is because the natural gestures and facial expressions of the avatars in the immersive social virtual reality interaction greatly promote the sense of coexistence and sense of the user. Second, Interaction functions through various channels should be considered. The interaction between avatars over different channels conveys a great deal of information and meaning during the conversation, and makes the virtual avatar a real conversation partner. Third, The nature of the interaction between avatars and their virtual environments should be reflected in their designs. In social virtual reality, when the environment is changed by one user’s behavior, the other participants who perceive the change feel the coexistence and the sense of presence that they are with the other. The study could develop avatars for immersion social virtual reality and use them as academic and theoretical data to enhance the satisfaction of users who experience a new communication environment through avatars and to develop positive effects in social virtual environments.

본 연구는 가상·증강현실의 개념 및 현황을 파악하고 현전감 개념과 결정요소를 논의하여 가상·증강현실 콘텐츠 디자인의 방향성을 조망하고자 한다. 또한 향후 현전감을 반영한 가상·증강현실 콘텐츠 디자인을 위해 이론적이고 체계적인 학술 자료를 제공하고자 연구되었다. 연구 범위는 가상·증강현실의 개념 및 현황 파악, 현전감 개념과 결정요소 분석, 현전감 결정요소와 가상·증강현실 콘텐츠 디자인 간 연관성 파악을 위한 사례 분석이며, 이를 종합하여 현전감을 반영한 콘텐츠 디자인 방향성 논의로 결론에 이른다. 연구 방법은 국내외 정보 DB 및 웹(Web) 검색, 도서 출판물을 통한 논문, 단행본 등 문헌조사와 분석을 중심으로 하였다. 연구 내용과 결과는, 첫째, 가상·증강현실의 기술 중심적 관점은 가상·증강현실의 폭 넓은 적용을 막고, 경험적 가치를 제공하는 콘텐츠 개발에 통찰력을 제공하지 못하였다. 수용자가 환경에 몰입하게 만드는 현전감을 가상·증강현실 콘텐츠 디자인에 반영한다면 수용자에게 높은 경험적 가치를 제공하고 새로운 미디어 활용의 확대를 기대할 수 있을 것이다. 둘째, 현전감 결정요소에는 개인적 요소, 사회적 요소, 환경적 요소가 있다. 개인적 요소는 감각의 폭과 감각의 깊이를 포함한다. 감각의 폭에는 방향감각, 청각, 촉각, 미각과 후각, 시각이 있으며, 감각의 깊이에는 질, 밀도, 양이 있다. 사회적 요소는 즉시성, 친밀성, 공유성, 적극적 상호 작용성이며, 환경적 요소는 감각적 변화의 능력, 환경적 변화의 능력, 범위, 일치성, 속도 등이 있다. 셋째, 현전감을 반영한 가상·증강현실 콘텐츠 디자인의 방향을 제시하면, 먼저, 인간의 감각요소를 이해하고 이를 충족시켜야 한다. 수용자의 현전감 촉발에는 감각자극이 큰 요인이므로 감각요소에 대한 다각적, 심층적 이해가 필요하다. 다음으로, 커뮤니케이션의 구조적 특성을 고려한 상호작용 요소의 적용이 필요하다. 전통적 미디어와 가상·증강현실에서 각각 이루어지는 커뮤니케이션 속성의 차이를 충분히 인식하고, 현전감 향상을 위한 상호작용 요소를 반영해야 한다. 마지막으로, 수용자 경험을 중심으로 효율성과 적절성을 고려하여 현전감 결정요소를 반영해야 한다. 가상·증강현실 콘텐츠 디자인에서 현전감의 결정요소를 동일하게 반영하는 것은 기술적 한계가 따른다. 콘텐츠의 목적과 컨셉에 맞는 요소를 선택하고, 이를 효율적으로 적용하는 것이 필요하다. 본 연구가 수용자의 경험적 가치를 고려한 가상·증강현실 콘텐츠 개발과 가상·증강현실의 대중적 보급확대를 위한 기초연구 자료로 활용될 수 있기를 기대한다. The purpose of this study is to understand the concept and status of virtual·augmented reality, to discuss the presences concept and its determinants, to examine the virtual·augmented reality contents design direction, It has been studied to provide systematic academic data. The scope of the research is to understand the concept and status of virtual·augmented reality, to analyze the case to understand the relationship between the presence decision factor and the virtual·augmented reality contents design, and It is concluded by discussing the direction of contents design reflecting the presence The research method focused on the research and analysis through domestic and foreign information DB and web search, literature through book publications, and monographs. The contents and results of the research are as follows: First, the technology - oriented view of virtual·augmented reality prevents the broad application of virtual·augmented reality and fails to provide insight into content development that provides empirical value. Therefore, if presence that makes the audience immersed in the environment is reflected in the virtual·augmented reality contents design, it can provide high empirical value to the audience and can expect to expand the use of new media. Second, there are individual factors, social factors, and environmental factors in presence decision – making factors. Personal factors include the width of the senses and the depth of the senses. The width of the senses includes direction, hearing, tactile sensation, taste and smell, and vision, and the depth of sensation has quality, density and quantity. Social factors are immediacy, intimacy, sharing, and active interactivity. Environmental factors are the ability of sensory change, the ability of environmental change, scope, consistency, and speed. Third, when presenting the direction of virtual·augmented reality contents design that reflects presence, first, we must understand human senses and satisfy them. Since sensory stimulation is a major factor in triggering presence, multifaceted and in-depth understanding of sensory elements is necessary. Next, it is necessary to apply interaction elements considering the structural property of communication. It is necessary to fully recognize the differences in communication property between traditional media and virtual·augmented reality, and to reflect interaction elements to improve presence. Finally, considering the efficiency and aptness of the audience experience, it is necessary to reflect the determinants of the present situation. It is technically limitless to reflect the determinants of presence in virtual·augmented reality contents design. Therefore, it is necessary to select the elements that match the purpose and concept of the content and apply it efficiently. It is expected that this research can be used as basic research data for developing virtual·augmented reality contents considering the empirical value of the audience and expanding the use of virtual·augmented reality in the future and increasing popularization.

Objectives : This study investigated the improvement effects of Pakistani (DF-a) and Chinese Ephedra herba-containing Gangjihwan (DF-b) on obesity in a high fat diet-fed obese mouse model. Methods : Eight-week-old C57BL/6N mice were divided into four groups: a normal lean group given a standard diet, an obese control group given a high fat diet, and DF-a and DF-b groups given a high fat diet with DF-a (80 mg/kg), and DF-b (80 mg/kg), respectively. After 8 weeks of treatment, body weight gain, feeding efficiency ratio, blood lipid markers, fat weight and histology were examined. Results : 1. Body weight gain and fat mass were significantly decreased in DF-a and DF-b groups compared with control. The extent of decreases was eminent in DF-a group. 2. Feeding efficiency ratio and circulating leptin concentration were significantly decreased in DF-a and DF-b groups compared with control, whereas circulating adiponectin concentration was increased in DF-a and DF-b groups compared with control. 3. Consistent with their effects on body weight gain and fat mass, circulating concentrations of triglyceride, glucose and insulin were decreased in DF-a and DF-b groups compared with control. 4. The size of adipocytes were decreased by DF-a and DF-b compared with control, whereas the adipocyte number per unit area was increased by them, suggesting that DF-a and DF-b decreased the number of large adipocytes. 5. Consistent with their effects on body weight gain, liver fibrosis was reduced in DF-a and DF-b groups compared with control. Conclusions : In conclusion, these results suggest that DF-a and DF-b not only decrease feeding efficiency ratio, plasma leptin concentration, and blood anti-obesity biomarkers, but also reduce fat mass, contributing to the improvement of obesity. DF-a and DF-b also inhibit liver fibrosis. In addition, these effects were similar between Pakistani Ephedra herba and Chinese Ephedra herba-containing Gangjihwan.
