Even though importance of nano-scale structure and compositional analysis have been getting increased, existing analysis tools have been reached to their limitations. Recent development of Atom Probe Tomography (APT), providing 3-dimensional elemental distribution and compositional information with sub-nm scale special resolution and tens of ppm detection limit, is one of key technique which can overcome these limitations. However, due to the fact that APT is not well known yet in the domestic research area, it has been rarely utilized so far. Therefore, in this article, the theoretical background of APT was briefly introduced with sample preparation to help understanding APT analysis.

In contemporary society, Labyrinth and maze are used with the same meaning. They are also used by translating various meanings. But labyrinth and maze are exactly different meaning. The purpose of this study is to inquire about difference for understanding essential meaning between labyrinth and maze. First of all, this study is to grasp composition principles and the characteristics of space through example of labyrinth and maze from ancient to contemporary, prescribe about essential meaning between labyrinth and maze and examine contemporary architecture which is fit for essential meaning. As compositional Principle in labyrinth and maze applied to comtemporary architecture, the labyrinth are centrality, property of one-sideness, determinable space, on the contrary the maze are out of centrality, property of multi-sideness, indeterminable space. Finally, The aim of this paper is analyze exhibition space that suit to the characteristics of composition principle and find the characteristics in labyrinth and maze. Examples of exhibition space are Aldo Van Eyck's 'Sculpture Pavilion', Kazuyo Sejima's '21st Century Museum of Contemporary Art', Ben van berkel's'Museum Het Valkhof'. These research we studied the visitor's circulation and the architectural structure in exhibition space with the spatial characteristics and the compositional principle in labyrinth and maze.

TiNi bodies were produced from (Ti＋Ni) powder mixture by spark-plasma sintering procerg. The sintering behavior was investigated through the measurement of change in density, densification rate, phase analysis and microstructure. Irrespective of heating rate, sintered bodies with above 97％ relative density could be obtained. TiNi with B2 structure was confirmed as the major phase and $Ti_2Ni,\;TiNi_3$, unreacted Ti, Ni as the second phase. Increase in heating rate suppressed a formation of intermediate phase during sintering process. Increase in holding time at sintering temperature led to a compositional homogenization.

After the industrial revolution, interior of living space have shifted from the spacial structure of existing wall partitions to visually and spacially continuous open space. And these open space can be recognized mostly in the common space of housing architecture of living, dining, and kitchen space composition. In order to understand the characteristics of space and compositional method, the works of Le Corbusier, W. Grupius, and F.L. Wright in their living, dining, and kitchen space design have been analized from the collected materials to make evaluation for the similarities and significance of their space compositional factors. therefore, this study is to analize space composition and design factor of the modern housing space of Living, Dining, and kitchen space variation and character of open space design factor for the practical use as an index of designing contemporary living space.

Compositional gradient CrNx coatings were fabricated using arc ion plating in Ar/$N_2$ gaseous mixture by gradually increasing $N_2$ flux rate from 0 to 120 SCCM. The effect of negative substrate bias on the film microstructure and mechanical properties were systematically investigated with XRD, GDOES, and SEM. The results show that substrate bias has an important influence on film growth and microstructure of gradient CrNx coatings. The coatings mainly crystallized in the mixture of hexagonal $Cr_{2}N$ and fcc CrN phases. By increasing substrate bias, film microstructure evolved from an apparent columnar structure to an equiaxed one. With increasing substrate bias, deposition rate first increased, and then decreased. The maximum of deposition rate was 15 nm/min obtained at a bias of -50V.

CIGS solar cell with copper, indium, gallium and selenium is a second generation solar cells for the lowering of the manufacturing cost. The relative ratio of the four elements is one of the most important measurement issues because the photovoltaic property of CIGS solar cell depends on the crystalline structure of the CIGS layer. However, there is no useful analysis method for the composition of the CIGS layer. Recently, AES depth profiling analysis of CIGS films has been studied with a reference material certified by inductively coupled plasma optical emission spectroscopy. However, there are some problems in AES depth profiling analysis of CIGS films. In this study, the in-depth profiling analysis was investigated by secondary ion mass spectrometry (SIMS) depth profiling analysis. We will present the compositional depth profiling of CIGS films by SIMS and its applications for the development of CIGS solar cells with high efficiency.

The compositional and morphological analyses have been carried out by employing XRD, EPMA, and SEM for the black-colored precipitate which is formed on the surface of heating appliances by heating tap water. XRD analysis has showed that the precipitate was mainly composed of calcium carbonate with a crystal structure of calcite. Also, small amounts of precipitate by SEM showed that the microscopic shape of the precipitate was usually angular spherical.

Recently, many cosmetic researchers have been focused on the development of high functional cosmetics including anti-wrinkle and whitening. In these studies, they couldn't afford to pay a deep attention to stable encapsulations for unstable materials and efficient drug deliveries for them. Particularly, in order to show a degree of instant effects as cosmetics, they can't also ignore moisturizing effect enough to satisfy customers just after applying and its maintenance by improving the function of skin barrier as well as above two effects. Therefore, skin analogue systems have attracted considerable attention in the view of structural and compositional similarity to intercellular membrane in stratum corneum. And, some models for skin analogue composition were developed to improve the function of skin barrier, stably encapsulate unstable materials such as retinol, vitamin B, C, E, etc., and control their skin penetration in order to show good effects as cosmetics. In this study, we suggest the new skin analogue model having the compositional similarity as well as conventional structural ones. Our skin analogue membrane(SAM) is mainly composed of ceramide/ cholesterol/phosphatidylcholin/fatty acids and its structural defects are compensated by including cholesterol amphiphile and controlling the ratio of ceramide/cholesterol. It was possible to confirm the formation of skin analogue membrane having highly-densed multilamella structure and compare them according to the change of each ratio with a polarized microscope, X-ray diffraction. More detaily, we observed their structures with a electron microscope(TEM). Finally, we dispersed them in excess of continuous water phase, observed the formation of maltese-cross liquid crystalline and measured the efficiency of drug deliveries and moisturizing effects.

The study on architecture can be started with the aesthetic attitude which cognizes it as the art of the space. Architectural space as the subject of the aesthetical study, however, has been ignored such a long period though it should be centered of the whole architectural theory. Even it has not been dealt with independently but just only as a part of aesthetic or artistic field. Also it is true that academic approach to the architectural space as per the aesthetic cognition has not been done so satisfactorily. This study, therefore, aims at prescribing compositional scope from aesthetic cognition of architecture understanding the rational function, mechanic structure, and artistic beauty by man's subject standard of judgement as per the space, the special sphere of architecture. For the absolves, the architectural space in this study is not approached as the spatial art with the meaning of being included the arts general, but with the meaning of intrinsic peculiarity of architecture, based both in practicality of scientific concept and arts of the aesthetic notiov. In order words, the essence of architecture can be prescribed as the architectural realities as the functional, formal and symbolical space not simply the spatial art, and its real but aesthetic meaning can be cognized aesthetically.
