The purpose of this study was to analyze University student's dietary behavior for processed foods and recognition on food nutrition labelling according to the degree of health concern. For this study, 302 University students in Gyeonggi region was surveyed by questionnaire from May in 2016 and it included the questions about general matters, dietary behavior on processed foods, and the food nutrition label system. It was analysed by SPSS win 23.0 program. And the results are as follows. According to the result of the factor analysis, the preference of processed foods were showed 3.21~3.97. There were significant differences in milk and milk products preference according to health concern (p<0.05). Also frequency of processed foods was shown significant differences in milk and milk products, noodles, beverage, and fast food (p<0.05), whereas no significant differences were found in meat products, snack, bread and frozen food (p>0.05). Also, the processed food purchase consideration according to health concern was shown significant differences in nutrition, origin, manufacturing company (p<0.05), whereas no significant differences were found in taste, price, exterior, brand, and shelf life (p>0.05). Thus, it is necessary to do continuing public relations and to provide more opportunities for nutrition education so that the University students may obtain right dietary behavior on processed foods and the system of food nutrition indication be established properly.

According to the recent report, the lighting energy consumption of commercial buildings reaches to $30%\sim40%$ of the total energy consumption. It is more than that of cooling & heating energy consumption and it is the major target of energy-saving policy. It is obvious that they are interested in natural lighting device such as Light-shelf for the purpose of raising the lighting energy-saving efficiency. In most of highly developed countries, a thorough study on Light-shelf makes it possible to propose a practical plan while at home there leaves much to be desired to study a guiding principle of optimum plan in spite of its efficiency based on experiments using scale4 model and analysis of simulation. Aiming at making an optimum plan of Light-shelf suitable for the domestic situation, this study is worked by experiments using light-shelf and analysis of variables using illumination program. The experiments is to analyse the efficiency of Light-shelf on condition of the sky and the analysis is to make the simulation using illumination program. This study is composed of 1) the analysis of light with some variables such as presence of light-shelf and degree of angle using 1/2 scaled model 2) making the simulation using Lightscape, illumination program, In brief, concerning presence of light-shelf, it causes little difference in its efficiency in the overcast sky, whereas it decreases an illuminance of window side and provides inner side with the light, which decreases the ratio of the maximum to the minimum inner illuminance and makes the inner of illuminance to range evenly in the clear sky. On degree of angle, as the daylight increases in proportion of degree of angle, the ratio of the maximum to the minimum inner illuminance decreases, which makes it possible to increase the proportion of inner daylight.

This study evaluates how much D/H and enclosed effects are closely related with each other centering around the spaces of cities in Japan. The partial ranks of the degree of angle in D/H and of the enclosure of the real spaces which the experimenter feels are measured through the method of partial rank correlation analysis on the sane objects. The result shows that all 42 samples(0.49), 25 interior space samples(0.63), and 17 exterior samples(0.59) are analysed to be less correlated. Seen above, there is limit to explaining modern spaces with the degree of angle in D/H. The result reveals that the space structure of modem cities consists of a lot more complex elements, so it is not suitable to evaluate the spaces of cities with the past theories of D/H and enclosed effect. Therefore, to evaluate the enclosed effect, a new evaluation model and a study of influential elements of city spaces and enclosed effect should be developed.

It is characteristic that houses designed by Adolf Loos show commonly a contradictory aspect between the exterior and interior. The exteriors of the houses are simple and on the other hand the interiors are affluent to the greatest degree. At that time, a stylized gorgeous decoration of the inner space had been prevailed in general among the historicism and Vienna Secession people, and such an inner spatial conception as by Loos must have brought a turning point for the development of a new inner spatial conception which can by itself be called revolutionary. This study is gong to clarify the fact that Loos has been in full consideration of the emotional side basically for the human being in the conception of inner space, by complementing the respect that his conception of the inner spatial composition, concentrating purity, comfort and classicalism on the furniture. Despite the independency of the Loos furniture is near copying, different from existing creative conception, it can be meaningful in respect that it creates out a rather accustomed and still a new space thought adding a little transformation to the existing classical furniture. So this study is going to re-establish the characteristics of the Loos furniture which work as the greatest impact in the composition of affluent inner space, the prototypical characteristics of that furniture, and the basical thinking system of Loos which can be found out in a little transformatiov.

Residential space has come to maintain a degree of specialization dependent upon the division of space according to function, while roles and functions have either expanded or ceased to exist corresponding to shifts in social values. However, various human behaviors connected to lifestyle habits and values are in fact becoming obsolete. This research will examine the mental, social, and functional aspects of the relationship between residential work spaces in modern homes and the sarangche as well as the communal space of daily and social life of the Chosun Dynasty to enhance the value and function of traditional residential space. As the boundary between family and work blurs with the home office environment of today, we are experiencing a deterioration of health and seeing problems in securing family domain as well as the prolonging of overwork. While the function of the traditional sarangchae encompassed a wider variety of activities than today's homes, the sarangchae achieved an efficient use of space divisions between rooms according to the particular purpose and situation. Accordingly, a reinterpretation of modern residential work space is needed through its connection to the sarangchae with consideration to the philosophy and values of the life of the noble class and the habits of our traditional lifestyle that have previously taken place within the sarangchae in an exterior space.

This paper focuses on the study of seismic behavior of steel reinforced concrete special-shaped column-beam joints. Six specimens, which are designed according to the principle of strong-member and weak-joint core, are tested under low cyclic reversed load. Key parameters include the steel form in column section and the ratio of column limb height to thickness. The failure mode, load-displacement curves, ductility, stiffness degradations, energy dissipation capacity and shear deformation of joint core of the test subassemblies are analyzed. The results indicate that SRC special-shaped column-beam joints have good seismic behavior. All specimens failed due to the shear failure of the joint core, and the failure degree between the two sides of joint core is similar for the exterior joint but different for the corner joint. Compared to the joints with channel steel truss, the joints with solid web steel skeleton illustrate better ductility and energy dissipation capacity, but the loading capacity and stiffness are roughly close. With the increasing of the ratio of column limb height to thickness, the joints illustrate higher loading capacity and stiffness, better energy dissipation capacity, but worse ductility.

To satisfy safety regulations of Economic Commission for Europe (ECE), the surface regions of automobile parts must have a sufficient degree of roundness if there is any chance that they could contact a sphere of 50.0 mm radius (exterior parts) or 82.5 mm radius (interior parts). In this paper, a new offset-based method is developed to automatically detect the possible sphere-contacting shape of such parts. A polyhedral model that precisely approximates the part shape is given as input, and the offset shape of the model is obtained as the Boolean union of the expanded shapes of all surface triangles. We adopt a triple-dexel representation of the 3D model to enable stable and precise Boolean union computations. To accelerate the dexel operations in these Boolean computations, a new parallel processing method with a pseudo-list structure and axis-aligned bounding box is developed. The possible sphere-contacting shape of the part surface is then extracted from the offset shape as a set of points or a set of polygons.

The study aims to develope techniques for generating digital elevation model(DEM) from IRS-1C PAN stereo image data. The bundle adjustment technique was used to determine the satellite exterior orientation parameters as a function of along-track lines. The first degree of polynomial was selected as a function of satellite attitude and position for each scan line. To evaluate the DEM and orthoimage generated, the resulted three dimensional coordinates of the 16 elevation points were computed with the map coordinates. The elevation test showed that root mean square errors of the DEM elevation was about $\pm{16.66m}$ meters.

In this study, both evaluations by visual imaging for exterior view of coating and by EIS were executed for epoxy primer coated specimens deteriorated by accelerated test, and comparison and analysis were carried out for 2 evaluation methods. In the comparison between total damaged area ratio acquired by image processing method and deterioration point, higher deterioration points were appeared for rusted specimens than for non-rusted specimens. It is attributed that deterioration point per unit area ratio given for rust is higher than for peeling. In the comparison between total damaged area ratio and EIS result, impedance of coating was largely decreased as about TEX>$10^4{\Omega}{\cdot}cm^2$ or less when rust area ratio is more than about 0.1%, and blistering area ratio is more than about 3%. Charge transfer resistance ($R_{ct}$) and double layer capacitance ($C_{dl}$) values were appeared for all specimens except 2 ones, which shows that water is accumulated and steel substrate is corroded at coated film-steel interface. In the comparison between deterioration point and EIS result, more than 10 points as deterioration point were given for specimens of below $10^6{\Omega}{\cdot}cm^2$ of impedance at low frequency. For specimens deteriorated by NORSOK cyclic test, impedance was lowest of all, though deterioration point was not high. It is thought to be attributed that coating system and accelerated deterioration condition of cyclic tested specimens were different from those of main specimens. From the result, it is thought that coating resistance can be relatively more decreased than deterioration degree estimated from exterior view under more severe corrosion environment or in the present of more complex deterioration factors.
