In recent rural areas, unlike the past, the young population is increasing with the growth of the agricultural industry and the quality of life-focused trend. Therefore, the rural areas need to more actively respond to the housing demands of the young generations. In this regard, this study aimed to research the housing conditions of the households with children and identify any problems. The study targeted 16 families with children in Deokpo-ri, Yeongwol-gun, Gangwon Province. The research was conducted based on the on-site case study, specifically face-to-face in-depth interview and on-site monitoring using the checklist by residential spaces. The research findings are as follows: The discovered issues include the storage size and safety issues in the movement space, failure to provide the space tailored to the characteristics of the children and the insufficient size and storage space in the living space and the size and safety issues in the sanitary space. Overall, it was identified that small and insufficient storage space in the house pointed out as the main issue in this research was getting the residents' life more uncomfortable and unreasonable, and the activities of the children made their parents do unnecessary behaviors and stressed out during the process of childrearing. Therefore, it is necessary to consider the space arrangement considering the organizing system, caring system and the behavioral characteristics of the children during the process of child-rearing.

Although the government has revised the child welfare act, institutionalized the establishment of local children's centers, and given financial support for them, there are a number of problems with respect to their operation. Specifically, one of main problems is their limited space. Diverse problems that go with the arrangement of limited space and usability have occurred, however there are only a few strategies to use limited space flexibly. This study assumed variability as one of the methods to solve spatial problems. As a basic research for the assumption, Analyzing the variable method and characteristics of domestic and foreign child-care facility guidelines was performed trying to take advantage of as a basic data in order to seek a variable scheme of local children centers' indoor space. For this purpose, study analysed the methods and characteristics of variability centering on aspects related to variability which are environmental design elements required by local children's centers as suggested in previous studies. The results are as follows. First, the variability of space should be planned according to activity and time, and consider the methods of division, storage, and other facilities necessary. Second, methods of variability in space can be classified into creating areas and structures that are variable. Third, as a result of analysing the environmental design elements required by local children's centers, this study discovered the following characteristics: multi-purpose usability through a combination of variable devices, transition through a variable space medium and setting up areas and expansion of indoor variability assuming usability through internal and external connections.

관음현상기는 세조가 미지산 상원사에 행차했을 때, 담화전(曇華殿) 상공에서 목격한 백의관세음보살의 화현 모습을 최항에게 일러 찬(讚)한 글이다. 관음현상기에는 화공이 그린 백의관음화현도가 붙어 있는데, 이 그림으로 인해서 조선 초기의 상원사의 모습을 알 수가 있게 되었다. 본 연구에서는 관음현상기에 실린 기록과 그림을 통해서 조선 초기 상원사의 경관성을 살피는 것에 주목하였다. 연구 결과, 조선 초기 상원사의 건물 배치나 공간구성 그리고 건물의 형식이나 조경처리에 있어서 다른 산지 사찰과는 다른 특별성이나 차별성을 확인할 수 있었다. 이러한 특별성이나 차별성은 상원사가 왕실의 원찰이라는 사격을 가지고 있었기 때문에 가능했던 것으로 보인다. 특히, 조경적 측면에서 볼 때, 경석은 주목되는 바가 큰데, 그것은 사찰조경이 주로 물을 재료로 해서 이루어졌다는 지금까지의 생각을 보완케 만드는 자료가 될 수 있기 때문이다.

As a new type of ballastless track, longitudinal continuous slab track (CST) has been widely used in China. It can partly isolate the interaction between the ballastless track and the bridge and thus the rail expansion device would be unnecessary. Compared with the traditional track, CST is composed of multi layers of continuous structures and various connecting components. In order to investigate the performance of CST on a long-span bridge, the spatial finite element model considering each layer of the CST structure, connecting components, bridge, and subgrade is established and verified according to the theory of beam-rail interaction. The nonlinear resistance of materials between multilayer track structures is measured by experiments, while the temperature gradients of the bridge and CST are based on the long-term measured data. This study compares the force distribution rules of ballasted track and CST as respectively applied to a long span bridge. The effects of different damage conditions on CST structures are also discussed. The results show that the additional rail stress is small and the CST structure has a high safety factor under the measured temperature load. The rail expansion device can be cancelled when CST is adopted on the long span bridge. Beam end rotation caused by temperature gradient and vertical load will have a significant effect on the rail stress of CST. The additional flexure stress should be considered with the additional expansion stress simultaneously when the rail stress of CST requires to be checked. Both the maximum sliding friction coefficient of sliding layer and cracking condition of concrete plate should be considered to decide the arrangement of connecting components and the ultimate expansion span of the bridge when adopting CST.

In this study, we designed, measured, and analyzed a rearranged L-shape magnetic resonance coupling wireless power transfer (MR-WPT) system for practical applications with laptops. The typical four resonator MR-WPT (Tx part: source loop and Tx coil; Rx part: Rx coil and load loop) is difficult to apply to small-sized stationary and mobile applications, such as laptop computers, tablet-PCs, and smartphones, owing to the large volume of the Rx part and the spatial restrictions of the Tx and Rx coils. Therefore, an L-shape structure, which is the orthogonal arrangement of the Tx and Rx parts, is proposed for indoor environment applications, such as at an L-shaped wall or desk. The relatively large Tx part and Rx coil can be installed in the wall and the desk, respectively, while the load loop is embedded in the small stationary or mobile devices. The transfer efficiency (TE) of the proposed system was measured according to the transfer distance (TD) and the misaligned locations of the load loop. In addition, we measured the TE in the active/non-active state and monitor-open/closed state of the laptop computer. The overall highest TE of the L-shape MR-WPT was 61.43% at 45 cm TD, and the TE decreased to 27.9% in the active and monitor-open state of the laptop computer. The conductive ground plane has a much higher impact on the performance when compared to the impact of the active/non-active states. We verified the characteristics and practical benefits of the proposed L-shape MR-WPT compared to the typical MR-WPT for applications to L-shaped corners.

Activities in the dwelling are inseparable from housing design. Spatial features often result from patterns of activities that take place within the dwelling. Activities are further elaborated to affect house plans, furniture, arrangement, and equipment. However, discrepancies still exist between housing design and behavior, where housing design often fails to accommodate activities and behavioral dimensions within the family and the dwelling. This paper addresses the relationship between dwelling activities and housing design by means of a qualitative study that aims to understand the needs of the Indonesian dwelling through activity analysis. To do so, the research adopts a methodology that involves collecting data from measurements of the house, house plan analysis, and photographs, in addition to in-depth semi-structured interviews with families. Taking Bandung as a case study, 9 houses and families were selected as respondents that share similar family life-cycles, number of family members, and building size. The findings from the study suggest that spacious and open plans are preferred by the family, while maintaining family privacy. Guest areas are used to host formal guests and to restrict visitor access in the house. Service areas such as kitchens and laundry areas are the core areas for household activities for cooking, laundry, and drying. To meet social activities such as community gathering, open plan design is necessary to allow flexibility of furniture reconfiguration to accommodate extra guests.

본 자기공명영상장치(MRI: Magnetic Resonance Imaging)의 구성 요소인 RF Coil의 성능은 영상의 신호대 잡음비(Signal to Noise Ratio)를 결정하는 장치이다. RF Coil의 성능은 민감도(Sensitivity)와 라디오주파수 필드 균질성(RF Field Uniformity)으로 나타내고, RF Coil에 의해 유기되는 라디오 주파수 자기장(B1 Field)의 세기는 RF Coil의 구조 및 배열에 따라 공간적으로 달라진다. MRI 신호의 크기는 RF Coil이 만들어내는 자기장의 세기에 의해 결정되기 때문에 RF Coil에 의해 형성되는 공간상의 B1 Field의 분포를 확인할 수 있어야 한다. 본 논문에서는 다채널 RF Coil 설계에 있어서 가장 기본이 되는 형태의 RF Coil 구조와 이의 B1 Field 분포를 Matlab을 이용하여 모의실험을 통해 확인 하였다. Matlab을 이용하여 계산된 기본 구조의 RF 코일이 형성하는 B1 Field 분포는 다채널 RF 코일 설계시 매우 유용하게 사용될 수 있을 것이다.

In this study, the cDNA of a new peptide from the venom of the scorpion, Buthotus saulcyi, was cloned and sequenced. It codes for a 64 residues peptide (Bsaul1) which shares high sequence similarity with depressant insect toxins of scorpions. The differences between them mainly appear in the loop1 which connects the $\beta$-strand1 to the $\alpha$-helix and seems to be functionally important in long chain scorpion neurotoxins. This loop is three amino acids longer in Bsaul1 compared to other depressant toxins. A comparative amino acid sequence analysis done on Bsaul1 and some of $\alpha$-, $\beta$-, excitatory and depressant toxins of scorpions showed that Bsaul1 contains all the residues which are highly conserved among long chain scorpion neurotoxins. Structural model of Bsaul1 was generated using Ts1 (a $\beta$-toxin that competes with the depressant insect toxins for binding to $Na^+$ channels) as template. According to the molecular model of Bsaul1, the folding of the polypeptide chain is being composed of an anti-parallel three-stranded $\beta$-sheet and a stretch of $\alpha$-helix, tightly bound by a set of four disulfide bridges. A striking similarity in the spatial arrangement of some critical residues was shown by superposition of the backbone conformation of Bsaul1 and Ts1.

The layer technique is to produce many memorable scenes by generating layers of new experiences on the existing ones as it is adding the cognitive layers on to the visually seen landscape. Its need is high for places whose landscape itself influences perception, value or expression and which determines the spatial and quality standards. The existing floor plan-based design methods have failed to be useful in generating complex visual experiences. In order to maximize the aesthetical landscape experiences in landscape planning, cognitive layers are needed which complement the input of adequate cognitive elements and the inter-element relationships. Here, layers are utilized to change the arrangement of the landscape elements and coordinate the cognitive flow so that the images could be connected and imagination could occur. A case in point is Anhyun Village in Gochang where physically distinctive layers are additionally set to make a visual experience enriching. The new landscape layers discover the fact that it provides diversity in experiencing the village landscape and forming the sense of beauty and that it is deeply immersed into the daily life of the village. Meanwhile, Guwau Village in Taebaek is an example showing the usefulness of various-layer setting in landscape planning in setting effective circulation planning. That is, the bottom line is the spacing-starting where and making it stay where for a few seconds, and the visual layers. It is also critical to encourage inducing circulation so that layers of the senses stimulating five senses could intervene. Lastly, Mulgeon-ri in Namhae is a case which directly made a parallel of the physical layers of the landscape composition and the cognitive layers of the landscape experience. Artificial landscape planning is mostly about manipulating of visual traits that people feel beautiful, but the layer technique is linked to how to make experiences enriching and renewed.
