The zodiacal light emission is the thermal emission from the interplanetary dust and the dominant diffuse radiation in the mid- to far-infrared wavelength region. Even in the far-infrared, the contribution of the zodiacal emission is not negligible at the region near the ecliptic plane. The AKARI far-infrared all-sky survey covered 97% of the whole sky in four photometric bands with band central wavelengths of 65, 90, 140, and $160{\mu}m$. AKARI detected the small-scale structure of the zodiacal dust cloud, such as the asteroidal dust bands and the circumsolar ring, in far-infrared wavelength region. Although the most part of the zodiacal light structure in the AKARI far-infrared all-sky image can be well reproduced with the DIRBE zodiacal light model, there are discrepancies in the small-scale structures. In particular, the intensity and the ecliptic latitude of the peak position of the asteroidal dust bands cannot be reproduced precisely with the DIRBE models. The AKARI observational data during more than one year has advantages over the 10-month DIRBE data in modeling the full-sky zodiacal dust cloud. The resulting small-scale zodiacal light structure template has been used to subtract the zodiacal light from the AKARI all-sky maps.

This research is aimed to analyze the basic characteristics of the 16 floor plans of 4 small-sized apartments in DaLian-City. Recently, there are increasing that a small-sized apartments for new younger generation in China. The younger ages intend to got a new floor plan types apartments according to own's life style. Also, a lot of construction company showed the many types of new residential space design during the last about 10 years, in DaLian City. The research results are summarized as follows: First, all of the floor plan types were '-' shape, 'L' shape. Second, there were several co-relational types of space plan between living room, kitchen and dining space. Those are LDK, L K, L DK, LD K. Third, the bedroom of the $30m^2$-floor plan size has an open-space design but over the size of $40m^2$-floor plan the space is closed design. Fourth, The number of bathrooms in all the floor plans is just 1 and it's placed beside the entrance except for B3, C4. The basic equipments of the lavatory was a toilet, a washbowl, a shower. A bathtub is installed in the floor plans greater than $60m^2$. Fifth, almost all of the characteristics of the spatial interrelation - each room position order - based on the location of the entrance. In particular, almost all of the bedrooms are furthest from the entrance for the most privacy.

As a neighboring country belonged to the same cultural sphere with the Northeast Asia, China is recently emerging as a center of the world's economy. The social transformations caused by the rapid economic growth are bringing changes in the Chinese housing culture and thus, it is considered that the identification of a user's need concerning a new housing space and social and cultural understanding on China are necessary. Accordingly, this research intended to conduct the basic research on the Chinese housing space design by observing the small apartment users in Shanghai area in terms of not only the tangible element of the residential space type but also the intangible elements such as lifestyle, values, behaviors, etc. The research range was limited to the kitchen area at the center of a house as a place where the exchanges among the family members are most frequently occur, and the research was carried out in the following methods. First, the effective user research method for the analysis of the Chinese small apartment kitchen users was studied through the literature investigation. Second, the 6 families of a research target were selected focused on the small apartments in Shanghai, China and the user research was performed using three methods of User observation, Video ethnography, and Contextual inquiry. Third, the research results were analyzed focused on the flow of human traffic in the kitchen area and user's behaviors. What were identified as a result take account of the human traffic movements in the kitchen areas around the sink-counter-cook top, cooking behaviors and meal areas outside of the kitchen. Through this, the need for the effective organization of the sink-counter-cook top, arrangement of meal area, and placement of storage by section for the kitchen space of China were drawn based on the understanding of the cooking process, and it was identified that such results require comprehensive understanding of Chinese housing culture.

In 1990s, the necessity of the Korean contemporary medium/small scale gallery as a place of experience rather than that of simple viewing has increased to meet from the requirements of the pluralistic and popularized society. The gallery makes efforts to form a collective street to cope with the influential of the power large scale cultural space as well as finding a novel direction in order to derive the regional sympathy in connection with the culture space of the neighborgood. In this paper, we study the 1990s Korean medium/small scale gallery in two aspects: First, the architectural techniques and elements which are introduces the audience to both interior and exterior spaces constructed by the 1990s gallery architecture, are investigated. The conventional architecture shows the blocking of the neighborhood and the trend of severance when viewing from both the architectural and the civil points. Secondly, we present the design characteristics from the several points of view such as conceptual, spacial, visual angles. The various trends of works in exhibition of the fine arts can provide a means for producing a great deal of variation in recent gallery architecture when viewing from a stage standpoint of exhibition space.

The New Solar Telescope (NST) at Big Bear Solar Observatory (BBSO) is the recently constructed world largest 1.6 m optical solar telescope on the ground. We took an observation of the north polar limb in H-alpha line center wavelength on 2009 August 26 with the instrument at Nasmyth focus of the NST and found a remarkable small-scale H-alpha eruption from 18:20 UT and 18:45 UT. The eruption occurred with a relatively slow speed of about 10 km/s in early stage and a slight acceleration up to 20-30 km/s in later stage. We also found that the eruption shows a deflection along the pre-existing magnetic field as well as several interesting features such as bifurcation, rotation, horizontal oscillation, and direction and thickness change of its structure during the eruption. In this talk, we will report the observational properties of the small-scale eruption observed by the NST and discuss their implication on magnetic reconnection.

In the design of stereoscopic clothing items, the 3D shapes of the space between clothing and body (SCB; Space shape between Clothing and Body) can be very important clues to improve the fit for various body shapes. Therefore, this research suggests a method for extracting the shape of SCB using the mold bra cup as an example. The SCBs were extracted from two kinds of 3D images, a small-breasted women's nude breast images and bra-wearing images. The the mold bra cups were compressed by wearing, and the outer and lower part of the SCBs could not be obtained because of the movement of the breast volume in the bras. Therefore, the SCBs could not be applied to the design of the mold bra cups directly. However, the suggested method can be useful when it is applied to stiffer clothing items and body parts whose shapes are not changed easily, such as a helmet or other body protectors.

The sun is a useful reference direction because of its brightness relative to other astronomical objects and its relatively small apparent radius as viewed by spacecrafts near the Earth. Most satellites use solar power as a source of energy, and so need to make sure that solar panels are oriented correctly with respect to the sun. Also, some satellites have sensitive instruments that must not be exposed to direct sunlight. For all these reasons, sun sensors are important components in spacecraft attitude determination and control systems. To minimize components and structural mass, some components have multiple purposes. The solar cells will provide power and also be used as coarse sun sensors. A coarse Sun sensor is a low-cost attitude determination sensor suitable for a wide range of space missions. The sensor measures the sun angle in two orthogonal axes. The Sun sensor measures the sun angle in both azimuth and elevation. This paper presents the development of a model to determine the attitude of a small cube-shaped satellite in space relative to the sun's direction. This sensor helps small cube-shaped Pico satellites to perform accurate attitude determination without requiring additional hardware.

Nowadays living space has been small-sized due to a rise in the standard of living, change of recognition on the increase of housing for the singles, and frequent movements of duty place, etc. and the furnitures naturally evolved assembly and multi-functionality. However, it retuned with an economic charge in the consumers and lost the uniformity in a small-sized living space as well since the furniture depended on the each miscellaneous household goods or products and came to be used. Hereupon it was demanded the system where the various furnitures are to fit to here. This study aimed at this point firstly examined a new environment change which it follows till a small living space is demanded through lots of literature, after understanding the concept of the system furniture, I classified expressive types of system furniture in modern environment and analyzed the design quality and characteristics in it by selecting well-known furniture magazines inside and outside of the country and extracting and analyzing system furniture images which are recorded in advertisements or articles. The objective of this study is to present MMC(Multi Modular Coordination, a system furniture design based on this analysis that inquiring the problems with function, structure, assembly which other existing system furnitures are facing enabled to apply a basic data in unit-module planning and by sampling embodiment modeling by uses.

The objective of this research is not only making the planning guides regarding a small-scale residential remodeling but also examining closely the social roles of the interior design for the poor and the underprivileged class by analyzing the residential remodeling cases. The scope of research includes 40 remodeling houses free of charge which are broadcasted in the TV program 'Love House'. Taking in consideration the characteristics of users like parentless or single-parent families and families with disabled persons, this study uses the spatial approach, user's convenience approach and psychological problem solving approach, in terms of the methodology. In result of the analysis of their interior design, first of all, it is essential solving the problem of limited house space by comparison with the family number. Second, the universal design concept for the family with disabled persons(72.5%), old persons or children is strengthened guaranteeing privacy in small and old interior space. Third, the interior design is focused in increasing communication among family members, because mental and physical obstacle would obstruct accessibility among them. This research shows the importance of the interior design which makes wide social roles contributing to create "welfare society".
