We live in the era of unlimited design competition. As the importance of design is increasing in all areas including marketing, each country does its best effort on design development. However, the preparation on protecting interior design rights by intellectual property laws(IPLs) has not been enough even though they occupy an important place in the design field. It is not quite easy to make a judgement on the similarity between two images having a single common factor because the factors which are composed of interior design have complicated interactive relations between them. From the IPLs point of view, designs with the similar overall appearance are decided to be similar. Objective evaluation criteria not only for designers but also for design examiners and judges are required in order to protect interior design by the IPLs. The objective of this study is the analysis of the possibility that a computer algorithm method can be useful to decide the similarity of interior design images. According to this study, it is realized that the Img2 which is one of content-based image retrieval computer programs can be utilized to measure the degree of the similarity. The simulation results of three descriptors(CEDD, FCTH, JCD) in the Img2 showed the high degree of similar patterns compared with the results of perceptual judgment by observers. In particular, it was verified that the Img2 has high availability on interior design images with a high score of similarity below 60 which are perceptually judged by observers.

The purpose of this study was on the development of jeans via conjoint analysis and marketing strategies for each segmented market. The questionnaire was composed vervel card and defining the proper marketing strategies for each segmented market. The 269 usable data was distributed to the Univ student and carrier women through multi- stage , ;ambling. The statistical results were processed by the SPSS, PC MDS, and MANZANOLA program. The used methods of statistical data were conjoint analysis, KYST, PROFIT, factor analysis, frequency, one-way ANOVA, SNK, and paired t-test. The results of this study can be summaries as follows: 1. In competitor analysis, Korean brands were in low price zone, but foreign in high price and character style zone. 2. There was significant differences Korean brands and foreign brands on evaluating. On the basis of the perceptual maps, most of Korean brands were evaluated as having a good price and most of foreign brands were evaluated as having a good design. 3. The optimal jeans has the well-known brand, the price of less than 30, 000 won, traditional style, and good quality. In four attributes of clothing buying process, brand is most important attribute of jeans. Segment market 1.All the jeans that they have is Korean brand. Income, amount spent per month on clothing, how many having jeans is low market. Self-centered factor is lowest. In the clothing sari ales lifestyle, they considered most conviniance. Segment market 2-They have one foreign brand jeans. Income, amount spent per month on clothing, how many having jeans is low market. Self-centered factor is lowest Segment market 3-They have two foreign brand jeans. Income, amount spent pet month on clothing, how many having jeans is high market. Self-centered factor is high. In the clothing variables lifestyle, they considered brand, continuance, and character. Segment market 4-They have more than three foreign brand. Income amount spent per month on clothing, and how many having jeans is high market. Self-centered factor is high. In the clothing variables lifestyle, they considered most brand, and character.

In this paper, we propose a parallelization method for a High Efficiency Video Coding (HEVC) deblocking filter with transform unit (TU) split information. HEVC employs a deblocking filter to boost perceptual quality and coding efficiency. The deblocking filter was designed for data-level parallelism. In this paper, we demonstrate a method of distributing equal workloads to all cores or threads by anticipating the deblocking filter complexity based on the coding unit depth and TU split information. We determined that the average time saving of our proposed deblocking filter parallelization method has a speed-up factor that is 2% better than that of the uniformly distributed parallel deblocking filter, and 6% better than that of coding tree unit row distribution parallelism. In addition, we determined that the speed-up factor of our proposed deblocking filter parallelization method, in terms of percentage run-time, is up to 3.1 compared to the run-time of the HEVC test model 12.0 deblocking filter with a sequential implementation.

The present study investigated the perceptions of food adopted by Koreans using the characteristics of taste and nutrition. Two hundred and nine Korean subjects were surveyed including University students and adults from many diverse social backgrounds. The subjects sorted pictures of foods according to two conditions, how tasty and then how nutritions they thought the foods were using the Q-method. These pictures included two sets, one for individual food items and the second depicting typical Korean meals, yielding a total of four conditions, This methodology effectively addressed any language barrier as pictures and words in both Korean and English were used. It was an effective tool for allowing the identification of perceptual structures and indicating how prevalent they were across samples. The data were factor analysed and the resulting factor scores interpreted. Meat was regarded positively in all four conditions. Individual sweet foods were preferred by younger subjects while individual traditional foods were preferred by older subjects. Traditional Korean meals were also favoured while processed meals were not. Nutritionally, proteins were more valued than carbohydrates, fibre and vitamins. Meals that contained protein and were regarded as filling and sustaining were regarded positively. The implications for nutrition education were discussed.

The purpose of this study is to identify the perceptual differences among independent elderly relative. to falls risk associated with specified environmental design factors. The sample consisted of 135 independent elderly who live in Ulsan. The data were collected by utilizing questionnaire which included demographic information, and environmental design assessments accompanied by line drawings. The data were analyzed by using SAS program. The major findings were as follows: (1) There were 35(25.9％) elderly experienced fall(s) within one year and about half of the fallers fell more than once. (2) The elderly perceived lighting is the most hazardous interior design factor related to increased risk of falls. (3) There was a significant difference among age groups on perception of lighting as interior design factors and the elderly perceived differently floor as interior design factors by their perceived health status.

In the speech system, for example hearing aid as well as speech communication, speech quality is degraded by environmental noise. In this study, to enhance the speech quality which is degraded by environmental speech, we proposed an algorithm to reduce the noise and reinforce the speech. The minima controlled recursive averaging (MCRA) algorithm is used to estimate the noise spectrum and spectral weighting factor is used to reduce the noise. And partial masking effect which is one of the human hearing properties is introduced to reinforce the speech. Then we compared the waveform, spectrogram, Perceptual Evaluation of Speech Quality (PESQ) and segmental Signal to Noise Ratio (segSNR) between original speech, noisy speech, noise reduced speech and enhanced speech by proposed method. As a result, enhanced speech by proposed method is reinforced in high frequency which is degraded by noise, and PESQ, segSNR is enhanced. It means that the speech quality is enhanced.

Human observers perceive a contour where no line or edge is given (subject contour), such as the border between gratings of thin lines offset by half a cycle. Subjective contours occur in a wide variety of circumstances in nature. A common factor in all such figures in the perception of a surface(contour) occuluding part of a background, i.e. subject contours are always accompanied by subject surfaces. Some examples about these kinds of figures are given by kanizsa trangle or square. Ph;ysiological observations are reported in which the perceptual phenomenon that some simple examples of subject contours are perceived as images (gigures; contours) through physiological experiments was investgated. In this paper, we proposed a neural network extracting the induce dstimuli for the perception of subject contours based on the visual mechnism. This visual mechnism is proposed by hubel & wiesel's paper.

Listeners' perception toward stuttering has been considered an important factor to the diagnosis and treatment of stuttering. This study intended to examine perceptual differences between speech language pathologists and laypeople toward children and adults with stuttering. A Total of 102 subjects were surveyed. speech language pathologists' perception was more stereotypical than that of laypeople. laypeople perceived adults and children with no significant differences but, clinicians viewed adults more stereotypically. speech language pathologists were not influenced by experiencer, but experienced laypeople perceived children more negatively although people who have stuttering family members showed a less stereotypically. item analysis revealed that both groups showed different perspectives between adults and children with stuttering.
