Of the vast number of plant taxa in the world, the wood is one of the most useful resources. It is important to identify the fibers of wood and pulp for the plant taxonomy and for the uses, but we do not have enough information on them, on them, especially for the computerizd data. The fiber identification is one of the difficult tasks. In addition to the plant taxonomy and the fiber-using industries, such identification is also important in many other fields, including education. document examiners, etc. For these purpose, the fibers should be exactly distinguished. The TISS system I have programed to identify various woods would also be useful in the identification of fibers by the genus and species in the features of unknown samples and in searching the features of a species based on its scientific name. Such searching programs are being developed in many other countries with a view to searching for the species name by using the features of the cells of the woody materials. With the survey of all the available literature, the features of the fibers of 124 species both of softwood and hardwood were examined under the electron and optical microscopies. Each species were coded and carded by the feature, and the databases were built. The microscopic were inputted into a personal computer program called and by a slide film scanner. The new computer program called TISS 2 was developed using C computer language. Korean language fonts were added to the TISS 2. The TISS 2 can be in adding and searching a image of fiber features both of a known fiber and an unknown fiber. The databases were corded for the DELTA system with was developed by Dallwitz and Paine in Australia, 1986.

가구는 실내에서 다른 구조물과 잘 어울리는지 확인하는 것이 구매결정에 있어서 필수적이며 COVID-19 사태로 인한 언택트 마케팅 상황에서는 더욱 중요한 요소가 되고 있다. 이에 따라 가구 배치 인테리어 시뮬레이션을 위해 ARCore, ARKit 등 AR(Augmented Reality) 오픈 소스의 등장으로 AR을 이용한 길이 측정법이 등장하고 있는 추세이다. AR를 이용하는 이러한 기존 방식은 평면 카메라 이미지를 토대로 깊이 맵(Depth Map)을 생성하고 복잡한 입체화 연산이 수반되는 방식이라 스마트폰을 사용하여 정확한 실내 크기 정보가 요구되는 작업에서는 한계가 드러난다. 본 논문에서는 ARCore, ARKit 사용 없이 스마트폰에 내장된 가속도 센서, 자이로스코프 센서만으로 정확한 실내 크기를 측정하는 방법을 제안한다. 또한 제시된 기법을 이용한 활용 예제로 미리 디자인된 방 인테리어를 각방에 맞게 적용하는 방법을 제시하였다.

There is a demand for a complex cultural space of play, leisure and education, a kids cafe, which will replace a playground just for kids as awareness for the need of a space where parents can spend leisure time with their own children and can take a rest grows, Thus, this study aims to find features for user satisfying kids cafes by conducting observations of the kids cafes and user survey. This study selected 12 kids cafes, 3 kids cafes per type (play focused, cafe or restaurant focused, education focused, multipurpose focused), in Seoul which were built after 2007 and conducted surveys on space planning and spatial characteristics by users and types and the level of satisfaction. As a result, the play focused kids cafes are used the most and the multipurpose focused kids cafes are used the second most. So the reason for using kids cafes is for the play of children. Also the overall satisfaction level for kid cafes were above the average except for the price. The result of this study showed that there was differences of satisfaction based on the type of user satisfaction, size of children space, finishes, colors, furniture and accessories, sanitary conditions. For the overall satisfaction, users were satisfied with the interior space, however, users were unsatisfied with functional parts, such as toys, foods and educational program. The results of the analysis showed that based on the types of the kids cafes, users' satisfaction rate for space size for the children, finishes, colors, furniture and accessories, sanitary conditions were different and for the functional parts, the satisfaction rate was different in all aspects. Also, in overall, the educational focused type users showed higher satisfaction rate than other users. Finally, the level of satisfaction is different by type of kids cafes and we have to consider the level of satisfaction of the users in order to plan kids cafes which meet the demand of the users.

Environmental conditions are known to impact human health and behavior, emotions such as pleasure, anxiety, and depression, and reduce stress. Interior design that elevates emotional comfort and satisfaction can help improve mental health and well-being. This study is a systematic review that analyzed previous empirical studies that explored the effect of interior design elements on the user's emotional response which is quantitatively evaluated by bio-signal and qualitatively evaluated through self-reported questionnaire surveys. This paper aims to derive the attributes of interior design and biometric indicators that affect the user's positive emotion through the synthesis of previous studies and to confirm the feasibility of measuring bio-signals as an objective evaluation tool for architectural design and as a quantitative research method. As a result of the review, the biometric data from EEG, fMRI, ECG, EMG, GSR, and eye-tracking were used to measure the participants' emotional responses, which were manifested as positive or negative depending on certain attributes of interior design such as the form, color, lighting, material and furniture. The attributes of interior design related to the positive emotional response were the curved shape, high ceiling, openness of space, and subdued tone colors. Standard lighting conditions and wooden spaces were related to stress reduction in terms of comfort and relaxation. The free arrangement of furniture was related to the user's positive emotions. On the other hand, consistent experimental protocols could not be found, and although the sample sizes of the studies were small, the studies have demonstrated the feasibility of the emotional response measurement by using the biometric data. Therefore this method can be a useful objective tool in the measurement of human-centric data in architectural design, and to develop the evidence-based design to induce positive emotions and minimize stress.

In Korea, the construction company has provided houses through apartment sales system. Residents have obtained a variety of information about their future house by visiting a sample house called "the model house" before they purchase home. Advanced technology such as web-based VOD or Virtual Model in recent years has gradually replaced those built environment. In 2009, the Ministry of Land, Transport and Maritime Affairs announced the restraint to the construction of sample houses. Instead, they highly recommended a Virtual Model House as an alternative solution. This study aimed to propose how to design the user-oriented virtual model house through the experiment and survey research. The 3D virtual model house of 85m$^2$ apartment was built and presented by two types (Type A: Bird's Eye View, Type B: Walk through View) on the web page. The subjects evaluated presence, spatial perception and cognition, and usability of each type after exploring them. The results are as follows. (1) The subjects' evaluation of presence showed Type B has more negative effects than Type A such as feeling dizzy or tired even if their values were not so high. (2) The subjects perceived and cognized both types of virtual model house more realistic for the expression of volume of space, the size of opening, and the arrangement of furniture than that of wall finishes and materials. (3) The usability of Type A was significantly higher than that of Type B.

Recently, public interest in housing defects, such as construction errors, occupiers' complaints, faults in production, and so on, is increasing. In addition, the construction requirements of high-rise residential buildings have increased, due to the higher prices of urban areas, especially in metropolitan areas. While previous research has focused on the defects occurring in apartment housing complexes, research has not been carried out on the defects occurring in high-rise residential buildings. In this paper, the defects patterns and characteristics of high-rise residential buildings are examined and analyzed and a defect management plan is then suggested. In order to do this, we collected the defects data of high-rise residential buildings recorded by 2,299 of 2,327 occupants. The defect occurrence rate (DOR) in the residential area is 98.8%. The frequency rate of defect occurrence over the total defect occurrence since building completion is 63.28% during the first year, 24.63% (second year), 6.88% (third year), 2.27% (fourth year), and 2.53% (fifth year). The result of correlation analysis between work types showed that there is a relationship between the built-in furniture and electronics (F&E) and painting works, and the F&E and masonry works, such as marble finishing. We expect that this research will assist in the efforts to decrease the number of defects in high-rise buildings.
