This study is to analyze fashion phenomenon according to the concept of the characteristics of freewheeling to explain the de-constructive, eclectic, avant-garde tendencies in Contemporary Fashion. This study is to elicit the aesthetic characteristics through 400 pieces of visual data analysis from 2001S/S to 2011F/W that have the characteristics of freewheeling, nontechnical experiments do away with the classical form. The oriental ideas include the thoughts of different tastes that break the stereotypes according to the Western values and the pursuit of unconventional beauty. These also insist that everything in the world including human-being, nature and creation is not divided into two equal parts, and even beauty and ugliness originated from one. This study is to find the possibility of interpreting oriental aesthetics with open concepts that transcends the boundaries of full availability, unlike the Western values that accommodate the relative concept of the pursuit of diversity. Therefore, integrated and systematic approaches of oriental aesthetics that place much value on the coexistence of antithetic concepts are needed to understand the ambiguity of complexity and diversity in Contemporary fashion design.

This study intended to develop and produce a modern form of fashion design for the Korean creative dance performance, 'Crazy Skirt Collage', which expressed conflict between internal ego and a persona in a woman. The qualitative method was used to analyze literature review, internet search and visual data of historically important cases related to the theme. Based on the analysis, the fashion design of the dance performanre by Hwang Hee-Yeon that was actually staged on Towol Theater, one of the Seoul Arts Center, was produced. The results wire as follows; First, the study confirmed a change of persona that revealed a female's animus strongly as it moved into the modern time. Second, the female's persona was expressed through long skirts, slips, dress shoes, handbags, military shoes, dresses with long zippers, trousers, wedding dresses and Korean full skirts during the performance, while the female's animus through male coats, panties, big bags and clock. In conclusion, it is necessary to study new expressive methods, that is, dance clothes using advanced equipment such as lights, videos or other variety of materials. It is also important to understand aesthetics of modern women's ordinary lives and to adapt ordinary clothes to dance clothes in various methods in order to express their modern lives appropriately through Korean creative dance.

The engineering equations, which have been used in many engineering companies, were employed for the dynamic modelling part in order to develop the naturally circulated boiler simulator. The fuzzy algorithm, which is similar to the algorithm of making decision by the human being, was developed for the boiler simulator controller and its simulated variables were compared with those of classical PID simulations to verify the stability and the effectiveness of fuzzy controller. The simulator is for the naturally circulated boiler and the main components are the furnace, the drum, the super heater, and the economizer. The combustion and thermal radiation dominant equations were used within the furnace and the mass conservation and the energy rate balance equations were employed for the drum part. The heat transfer rates were calculated using the logarithmic mean temperature differences both for the super heater and for the economizer. The simulations are very useful to understand the boiler operations and the engineering design of the main components. The main program was developed under the PC window condition by linking the fuzzy controller to the main boiler program using the Visual C++ language. The various operational conditions such as the abrupt changes of load, the changes of water supply pipes and the diameter of drum were simulated.

More complex radiotherapy techniques using multi leaf collimation(MLC) such as intensity-modulated radiation therapy(IMRT) has been increasing the significance of verification of leaf position and motion. Due to the reliability and robustness, quality assurance(QA) of MLC is usually performed with portal films. However, the advantage of ease of use and capability of providing digital data of electronic portal imaging devices(EPIDs) have attracted many attentions as alternatives of films for routine quality assurance in spite of the concerns about their clinical feasibility, efficacy, and the cost to benefit ratio. In our work, the method of routine QA of MLC using electronic portal imaging(EPI) was developed. The verification of availability of EPI images for routine QA was performed by comparison with those of the portal films which were simultaneously obtained when radiation was delivered and known prescription input to MLC controller. Specially designed test patterns of dynamic MLC were applied to image acquisition. Quantitative off-line analysis using edge detection algorithm enhanced the verification procedure in addition to on-line qualitative visual assessment. In conclusion, the EPI is available enough for routine QA with the accuracy of portal films.

Visibility of a space have been defined in several different ways: such as the axial line covering a convex space, a convex space defining the fattest shape in a space and an Isovist field formed by a field of vision at a given vantage point. Isovist fields are referred to as a descriptive medium to describe a movement by reviewing and analyzing geometric properties in them. Many descriptive methods for analysis of three-dimensional isovist are applied to analyzing the morphological properties in a 3D space more realistically. Although these models are regarded as a more advanced method for describing spatial properties, they have pros and cons such as complex mathematical calculations and somewhat arbitrary calibration in addition to huge consumption of memory space. These difficulties lead to the development of a three-dimensional visual accessibility model that explores the implication of building shape on the calculation of isovist fields drawn on a 2D plane. We propose a conceptual framework of how to measure the isovist field not as a 3D volume but as a combination of 2D plane on the ground with the 3D building shape of it's facade.

Purpose: The purposes of this secondary analysis study was to examine prevalence, risk factors and unmet healthcare needs among adults with hypertension. Methods: A sample of 3,386 adults over the age of 40 with hypertension were drawn from the Korea Health Panel Study (2013). Using SPSS 22.0 version, descriptive statistics including frequency, percentage, chi-square and logistic regression were performed. Results: Results showed that 18.9% of the sample reported unmet healthcare needs with the most frequently cited one was financial burdens (43.2%). The reported experiences of unmet healthcare needs differed by gender, marital status, vision or hearing impairment, memory problem, impaired mobility, subjective health status, total family income, depressive episode and the difficulty in making decisions. The sample participants were more likely to report unmet healthcare if they had vision impairment, low income and perception that their health status as moderate to poor. Those without vision impairment were less likely to report unmet healthcare needs. Conclusion: The identified risk factors of unmet healthcare needs should be addressed which would enhance access both to health care and to resolution of unmet healthcare needs. Since visual ability seems to impact perception of unmet healthcare needs, it may be useful to find ways to address this factor.

The conventional machine vision system which has uniform rectangular grid requires tremendous amount of computation for processing and analysing an image especially in 2-D image transfermations such as scaling, rotation and 3-D reconvery problem typical in robot application environment. In this study, the imaging system with nonuiformly distributed image sensors simulating human visual system, referred to as Ploar Exponential Grid(PEG), is compared with the existing conventional uniform rectangular grid system in terms of image resolution and computational complexity. By mimicking the geometric structure of the PEG sensor cell, we obtained PEG-like images using computer simulation. With the images obtained from the simulation, image resolution of the two systems are compared and some basic image processing tasks such as image scaling and rotation are implemented based on the PEG sensor system to examine its performance. Furthermore Fourier transform of PEG image is described and implemented in image analysis point of view. Also, the range and heading-angle measurement errors usually encountered in 3-D coordinates recovery with stereo camera system are claculated based on the PEG sensor system and compared with those obtained from the uniform rectangular grid system. In fact, the PEC imaging system not only reduces the computational requirements but also has scale and rotational invariance property in Fourier spectrum. Hence the PEG system has more suitable image coordinate system for image scaling, rotation, and image recognition problem. The range and heading-angle measurement errors with PEG system are less than those of uniform rectangular rectangular grid system in practical measurement range.

WT(Wavelet Transform) is used to avoid blocking effect that is the disadvantage of JPEG using DCT(Discrete Cosine Transform). Because the proposed coding scheme is the same as JPEG, the proposed algorithm is compatible with that of JPEG. To achieve the goal, WT'ed image is reconstructed into 8$\times$8 coding block. Each coding block is quantized with the proposed weighting matrix that is derived from human visual characteristic and error analysis in WT'ed domain. By experiments, the proposed algorithm is superior to JPEG, in terms of PSNR(Peak Signal to Noise Ratio) and WMSE(Weighted Mean Square Error).

Chemical feature based quantitative pharmacophore models were generated using the HypoGen module implemented in DS2.5. The best hypothesis, Hypo1, which was characterized by the highest correlation coefficient (0.96), the highest cost difference (61.60) and the lowest RMSD (0.74), consisted of one hydrogen bond acceptor, one hydrogen bond donor, one hydrophobic and one ring aromatic. The reliability of Hypo1 was validated on the basis of cost analysis, test set, Fischer's randomization method and GH test method. The validated Hypo1 was used as a 3D search query to identify novel inhibitors. The screened molecules were further refined by employing ADMET, docking studies and visual inspection. Three compounds with novel scaffolds were selected as the most promising candidates for the designing of Mcl-1 antagonists. Finally, a 10 ns molecular dynamics simulation was carried out on the complex of receptor and the retrieved ligand to demonstrate that the binding mode was stable during the MD simulation.
