  • Fashion pictorials are recognized as another form of communication method beyond the concept of simply providing information or being artistic photography. Therefore, it is believed that there is necessity to know methods of making a strong impression on people's conscience by effective usage of various presentation techniques that can be used in fashion pictorials. This research studied characteristics of closed form and open form of Wolfflin's precept of forms presented in scene construction. Depaysement technique was classified into three classes which are alien transportation of a part, deformation and ambivalence of an image through literature review of depaysement presentation technique. After studying the concept and characteristics of narrative applicable as the open form, Annie Leibovitz's "Alice's Adventures in Wonderland" published in an actual fashion magazine was analyzed as an empirical study based on the theoretical research. Through this study, potential of applying depaysement technique as a presentation technique of closed form and narrative as a presentation technique of open form on fashion pictorials was identified. Factors that infuse creativity and achieve uniformity in producing fashion pictorials were shown through analysis of actual fashion pictorials.

  • Unmanned Aerial Vehicle (UAV) has several advantages over conventional remote sensing techniques. They can acquire high-resolution images quickly and repeatedly. And with a comparatively lower flight altitude, they can obtain good quality images even in cloudy weather. In this paper, we discussed the state-of-the-art of the domestic and international use of UAV in agricultural sector as well as assessed its utilization and applicability for agricultural environment in Korea. Association of robotic, computer vision and geomatic technologies have established a new paradigm of low-altitude aerial remote sensing that has now been receiving attention from researchers all over the world. In a field study, it has been found that use of UAV imagery in an agricultural subsidy program can reduce the farmers' complain and provide objective evidence. UAV high resolution photography can also be helpful in monitoring the disposal zone for animal carcasses. Due to its expeditiousness and accuracy, UAV imagery can be a very useful tool to evaluate the damage in case of an agricultural disaster for both parties insurance companies and the farmers. Also high spatial and temporal resolution in UAV system can increase the prediction accuracy which in turn help to maintain the agricultural supply and demand chain.

  • The influence of oxygen concentration and CO$_{2}$ as diluent in oxidizer side on soot characteristics was studied by Laser Induced Incandescence, Time Resolved LII and Transmission Electron Microscopy photography in non-premixed co flowing flames. Through the comparison of TEM photographs and the decay rate of LII signal, suitable two delay times of TIRE-LII method and signal sensitivity ($\Delta$S$_{TIRE-LII/) were determined. The effects of O$_{2}$ and CO$_{2}$ as diluent in oxidizer side on soot formation are investigated with these calibrated techniques. The O$_{2}$+CO$_{2}$, N$_{2}$, and [Ar+CO$_{2}$] mixture in co-flow were used to isolate CO2 effects systematically. The number concentration of primary particle and soot volume fraction abruptly decrease by the addition of CO$_{2}$ to the co-flow. This suppression is resulted from the short residence time in inception region because of the late nucleation and the decrease of surface growth distance by the low flame temperature due to the higher thermal capacity and the chemical change of CO$_{2}$ including thermal dissociation. As the oxygen concentration increases, the number concentration of soot particles at the inception region increases and thus this increase of nucleation enhances the growth of soot particle.

  • The purpose of this study is to correct the nodule abundance of FFG (Free Fall Grab) sampler on KODOS (Korea Deep Ocean Study) area in North-East Pacific Ocean. The image analysis of sea-floor photography was carried out for correcting the abundance of nodules, and the image enhancement techniques and edge detection method were used to discriminate between nodules and sediments. The trace of nodules on sediments was detected to reduce the fractionation effect in calculating the coverage of nodules. The three methods, using the coverage of nodules, using the volume density, and using corrected volume density, were utilized for the correction of the nodule abundance. The method using the coverage of nodules was more convenient and available for the correction of nodule abundance than the other two methods. The method using the corrected volume density had the highest confidence level compared with the other methods.

  • The purpose of this research is to investigate the concept of the photomontage technique, one of the various photographic techniques, and to analyze the photomontage image through the patterns that appeared in 1990's fashions. Moreover, by making clothes using the photomontage image, the intention of this study to apply the technique in real life is achieved. The results of this thesis for making clothes utilizing image of the photomontage are as followings. First, the photomontage expands the variety of materials that can be used, because the clothes using the photomontage image are able to take any photo images. Second, two different eras can co-exist in a piece of work since a photomontage work can uses two images from different eras. Third, it allows greater adaptability by expressing variety and utility in the making of the casual styles using conventional photo materials. The conclusion of this study is that the clothes appearing in the late 20th century using the photomontage image have been developed corresponding to the accelerated development of photography, machinery, and technical skill in civilization. Trends break away from the conventional expressions of art. This is a new trend and direction in art that will effect culture in the 21st century. The photo montage image would show the possibility of a good unification between human being and machines.

  • Painting is well regarded as a stratified structure by the conservators and restorers. Hence, the scientific methods have been developed for the study of the interal layer of paintings. Examples of such methods are X-ray, infra-red, and ultra-violet photography. A more direct method is to look at the painting in cross section under the microscope and to analyze pigments using an electron probe X-ray micro analyzer(EPMA).In this research, I study and analyze twenty two Korean paintings of self-portraits including the first oil painting of Hui Dong Koh's self-portrait stored in the museum of Tokyo National University of Fine Arts and Music, employing these scientific techniques. The small fragments taken from the ground layers of the early oil paintings(1915∼1942)are analyzed using the EPMA. According to their main materials, the ground layers can be classified into five types ; 1. Lead white layer and double layer of calcium carbonate and lead white, 2. Zinc white with some mixiture of lead white, 3.Titanium white with some barium white, 4. Barium white, 5.Double layer of titanium white and zinc white.

  • Background: Oroantral communicating defects, characterized by a connection between the maxillary sinus and the oral cavity, are often induced by tooth extraction, removal of cysts and benign tumors, and resection of malignant tumors. The surgical defect may develop into an oroantral fistula, with resultant patient discomfort and chronic maxillary sinusitis. Small defects may close spontaneously; however, large oroantral defects generally require reconstruction. These large defects can be reconstructed with skin grafts and vascularized free flaps with or without bone graft. However, such surgical techniques are complex and technically difficult. A buccal fat pad is an effective, reliable, and straightforward material for reconstruction. Case presentation: This report describes three cases of reconstruction of large oroantral defects, all of which were covered by a pedicled buccal fat pad. Follow-up photography and radiologic imaging showed successful closure of the oroantral defects. Furthermore, there were no operative site complications, and no patient reported postsurgical discomfort. Conclusion: In conclusion, the use of the pedicled buccal fat pad is a reliable, safe, and successful method for the reconstruction of large oroantral defects.

  • People live in an environment which affects the human b by way of ‘Affordance’ .. And the interaction between h human and the surrounding environment arises ‘the sense of place' through adoptation. Considering the human emo¬t tional and psychological needs, besides the functionalones, for the design of environment gives ‘the place’ the h humanized atmosphere. Then the viewing-window, re¬f fleeting the dweller’s sensibility and aesthetic aspect, be¬c comes an important design element for the human interi¬o or atmosphere. G Generally, the view has the character of the Panorama a and sometimes of the Picture. And the viewing - window t transfigures the visual effects by ways of ‘Framing’, at t taching the ’Screen’ and ‘Successive development' of the views through openings on the wall. Hence this study w was developed from the aesthethic view-points of archi t tecture, cinema, picture and photography etc., and the c conclusions are as follows. T The ‘Frame’ limits the boundary of the view into a p particular area, while the ‘Screen’ changes the clear view t to an obscure one. And the wall-openings located with i intervals show the fragments of the outer view in a suc¬c cessive way. And these techniques applied to the viewing window make the viewer have the associated meanings d derived from the ‘Guided Projection'. So, the associative p psychology of the viewer complements the partiality, ob¬s scurity and brokenness of the view into a complete one, a and finally the view comes to be an aesthetic one to the v vIewer.

  • In order to clarify the characteristics of soot formation and oxidation in-cylinder of a diesel engine, it is necessary to diagnose accurately for combustion of in-cylinder. The past techniques for soot measurement have limitations in providing the characteristics of soot in a diesel engine, whereas, laser-based 2D imaging diagnostics have the potential to provide better temporally and spatially resolved measurements of the soot distribution. We rebuilt an optically accessible diesel engine which is similar to the conditions of a conventional engine and tried to measure soot distribution in a cylinder of the diesel engine using laser induced scattering(LIS) and laser induced incandescence(LII). Some results were acquired in this study. LIS and LII signal that show soot distribution of a in-cylinder were taken by ICCD properly. The signal of LIS was intenser than that of LII. Although they have some differences of signal intensity in early combusion period, both of signals show that they are generally similar in late combustion period, after ATDC 50 degree.
