In this paper, a new detection method of series arc-fault signals occurring at the wiring of home appliances is proposed. The discrete wavelet transform was used for the numerical analysis of the variation rate in peak, RMS, noise energy, shoulder of the arc-fault current wave. As a results, the arc distinction threshold value of these variation rates was about 0.1 in most cases. The arc-fault current of the loads with the active PFC circuit showed a high rate of variation in noise energy and shoulder, but arc-fault current of the loads without the active PFC circuit showed a high rate of variation in peak and RMS. The arc fault current in resistive loads showed a high rate of variation in shoulder.

This paper proposes a method to accelerate the evolution speed of individuals through hybrid reproduction of monogenesis and gamogenesis. Monogenesis as a reproduction method that bacteria or monad without sexual distinction divide into two individuals has an advantage for local search and gamogenesis as a reproduction method that individuals with sexual distinction mate and breed the offsprings has an advantages for keeping the diversity of individuals. These properties can be properly used for improvement of evolution speed of individuals in genetic algorithms. In this paper, we made relatively good individuals among selected parents to do monogenesis for local search and forced relatively bad individuals among selected parents to do gamogenesis for global search by increasing the diversity of chromosomes. The mutation probability for monogenesis was set to a lower value than that of original genetic algorithm for local search and the mutation probability for gamogenesis was set to a higher value than that of original genetic algorithm for global search. Experimental results with four function optimization problems showed that the performances of three functions were very good, but the performances of fourth function with distributed global optima were not good. This was because distributed global optima prevented individuals from steady evolution.

This study is about setting the weighed value of evaluation items for cultural tourism development project using AHP and it analyzed the cultural and ecological tourism infrastructure project in three cultural areas of Andong City. As a result of examining the reliability of evaluation items, it turned out to be 0.9, an appropriate level. In the analysis of weighed value, the items valued highly were in the order of validity of the plan, economic validity, validity of the policy. As for the detailed indices for the three that showed the highest weighed value, for validity of the plan, distinction of contents; for validity of the policy, compatibility of regional characteristics; for economic validity, sustainability were given high values. In the end, it could be concluded that as the cultural and ecological tourism infrastructure project in three cultural areas was delayed a lot more than previously planned, in order to flexibly respond to changing environment, it would be desirable to change parts of the previous plan before pushing ahead with it.

The effect of color evokes a certain feeling and affects behavior. Especially, an understanding and applying color are critical because well-designed color substantially contributes to quality and usability. In this study, the effects of three color components(hue, value, and chroma) on apparent warmth were investigated separately and relatively, and then feasibility of applying to the information display was examined. The result showed that the apparent warmth of 10 Hues was a U-shaped function declining from Red to Purple-Blue and increasing from Purple-Blue to Red-Purple with following order of color-circle. Chroma made the character of hues remarkably clear, so warm color becomes warmer and cool color becomes cooler if chroma gets higher. But value has no effect on warmth. These results propose that we can change the apparent warmth by varying chroma in the limitation of color use. And there was a sharp distinction between warm and cool color, Meanwhile, in the reading task of the graphical information, the subjects' judgment distortion overestimating or underestimating the actual degrees was ascertained. This result should be applied to control operator's sensitivity in accordance with the purpose of task and display.

Background: It is essential to distinguish between symptomatic- and asymptomatic radiographic acromioclavicular (AC) osteoarthritis (OA) because AC-targeted physical examinations are dubious. This study aimed to determine the diagnostic value of a preoperative AC injection in discriminating between symptomatic- and asymptomatic radiographic AC OA based on patient arthroscopic distal clavicle resection (aDCR) outcomes. Methods: Forty-eight patients who underwent aDCR for AC OA were included. Their satisfaction was objectified using a 5-point Likert scale and patient willingness to repeat the surgery. The Oxford Shoulder Score (OSS), the Subjective Shoulder Value (SSV), and the Numerical Rating Scale (NRS) were used to assess postoperative shoulder function and pain. Patients were subdivided into groups based on their good or minimal reaction to an AC injection (good reaction: ≥7 consecutive days of pain reduction, Minimal reaction: <7 consecutive days of pain reduction). Results: Twenty-seven patients had a good reaction and 21 patients had a minimal reaction to the AC injection (median follow-up, 45.0 months; range, 31.0-52.8 months). No significant differences were found in level of satisfaction (P=0.234) or willingness to repeat the surgery (P=0.861). No significant differences were found in OSS (P=0.612), SSV (P=0.641), NRS at rest (P=0.684) or during activity (P=0.422). Conclusions: This study found no significant differences between patients with a good reaction or a minimal reaction to an AC injection after aDCR surgery. The outcomes of this study seem to suggest that a distinction between symptomatic and asymptomatic radiographic AC OA is unnecessary, as all patients were equally satisfied with the outcome.

The major goal of this study is drawing design plan factors considering residents' life cycle and life style when remodeling design is needed. By drawing such design factors, the study will propose an alternative remodeling design plan. Such design method was defined as Multi-Dimensional module design method. And constructing data-system based on Multi-Dimensional module was secondary goal in this study. The details are as follows: Based on analysis of Residents' demand for remodeling and features of emotion-design applied to remodeling, the system which is suitable for application in remodeling design method was conducted. Based on the type of construction materials, the level value was set up according to emotion-factor application. Also, by conducting coding operation according to the distinction of construction materials, this study seeks the unit drawing method of information for constructing emotion-information system.

Since the 1980s the development of American art furniture was embodied its concept by second-generation furniture artists affected and educated from the first generation that has implanted art furniture fundamental values. Besides, embracing inevitably needs of the new era going with the social change rather than dwell on the nature of mere handicraft era, it has evolved with economic revival in the United States, the attention and increased consumption of the public, and ongoing government-sponsored. And more recently, the American contemporary Art Furniture faces another change in the non-boundary phenomena between art and design. American art furniture since the 1980s are summarized as three major trends: Art furniture embellished with traditional hand-craft, Art furniture featured the individualistic avant-guard characteristic, Art furniture eroded the distinction between art and design. By analyzing focusing on the furniture artists and their works in contemporary art furniture deployment aspects since the 1980s, the purpose of this study can be utilized as a method to measure the forward direction, internationally competitive, creativity, and artistic value of the domestic art furniture.

This study aims to develop the processed foods with chestnut and support their commercialization. Interview was performed with owner of Gongju chestnut food processing company and sensory evaluation was carried out by 103 male and female adults aged 20-70 using Likert 5 point scale-scoring test for chestnut processed food items developed. Nutrient contents of processed foods with chestnut were analyzed by Korea Food Research Institute. Commercialization support contents were high calorie low nutrition distinction, nutrition facts production and expiration date determination. We suggested 27 kinds of feasible chestnut processed foods. Among these, 10 items, chestnut pudding, chestnut glutinous rice cake bread, chestnut poundcake, chestnut burrito, chestnut millet pancake, chestnut soup, Yulpyeon, chestnut yakgwa, chestnut yeot, and chestnut yanggaeng were selected after consultants' assessment. Considering sensory evaluation, consultants' opinions, and company owners' opinion and status, chestnut poundcake and chestnut yakgwa were ultimately selected for commercialization support. Nutrient contents showed that chestnut pound cake and chestnut yakgwa were not high calorie low nutrition food. Expiration date was 10 days for chestnut pound cake and 6 months for chestnut yakgwa. By developing chestnut processed foods with high marketability, and supporting immediate commercialization, it is expected to increase high added value of chestnut.

Microsomal prostaglandin $E_2$ synthase (mPGES-1) is an enzyme that is associated with inflammation, pain, fever and cancer. Hologram quantitative structure activity relationship (HQSAR) was conducted on the series of MK-886 compounds acting as mPGES-1 inhibitors. A training set with 24 compounds was used to establish the HQSAR model. The best model was chosen based on the cross-validated correlation coefficient ($q^2$=0.884) and the correlation coefficient($r^2$=0.976). The model was utilized to predict the activity of the eight-test set of compounds giving the predictive $r^2$ value of 0.845. The descriptors of the model are based on fragment distinction (atoms, bond and connectivity) and fragment size (2-5 atoms). The atomic contribution maps generated from HQSAR were useful in identifying the important structural features responsible for the inhibitory activity of MK-886 inhibitors. Based on the generated model, the presence of hydrophobic biphenyl group seems to enhance inhibition of mPGES-1 that is in agreement with the previous experiments. In addition, it seems important for a halogen to be substituted to the biphenyl ring and for an acyl group to be attached to the indole moiety for enhanced activity.
