Purpose - This study attempts to extend the research in responsible luxury by identifying contexts where Corporate Social Responsibility (CSR) can promote luxury brands' evaluation. It contributes to the literature on consumer responses to CSR, and to responsible luxury in particular and demonstrates how dispositional consensus and luxury-CSR information of luxury brands affects consumers' evaluation of brand. Research design, data, and methodology - An experiment was conducted to test the relationship between brand evaluation and responsible luxury brands' CSR information using collected data through a survey in a large university of South Korea. Study conditions were manipulated with various product types to analyze the relationship in different product domains. Results - When consensus regarding sincere and altruistic motive of companies for CSR activity is high, the perceived fit between luxury brand and the type of CSR has no effect on brand evaluation. But, in case of lower consensus regarding the benevolent company motives, higher fit enhances evaluation than lower fit. Conclusions - In using consensus as a guiding factor to choose the type of charity with favorably view, the level of irrespective fit can help luxury firms to enjoy the benefits of better image. In case of low consensus donating to charities that are closely related to the brands' product or area of business seems to be fruitful.

The purpose of this study was to investigate the consciousness, knowledge and food preferences for the Korean traditional foods, using a questionnaire survey for 560 high school students in seoul. The data were analyzed with simple frequency, percentage, t-test, chi-square test, dispersion analysis, Pearson's correlation and hierarchical multiple-regression analysis using the SPSS/PC+ Package system. The results of the survey are summarized as follows ; Girls showed a more interest in Korean traditional foods than boys. The motive of having interest in korean traditional foods were through mass communication or home education. Most of students were preffered korean traditional foods and were proud of native foods. The most preffered foods were Kim-chi and beverage. and they thought that color, appearance, foodstuff combination of Korean traditional foods were better than those of foreign foods. they showed a tendency to decrease the use Korean traditional foods because it is difficult to cook and they have little time to cook. They have taken more Korean traditional foods at home. Most students were responded that it is necessary to develope Korean traditional foods at home for the succeeding of korean dietary life culture.

Improving the intrusion detection system (IDS) is a pressing need for cyber security world. With the growth of computer networks, there are constantly daily new attacks. Machine Learning (ML) is one of the most important fields which have great contribution to address the intrusion detection issues. One of these issues relates to the imbalance of the diverse classes of network traffic. Accuracy paradox is a result of training ML algorithm with imbalanced classes. Most of the previous efforts concern improving the overall accuracy of these models which is truly important. However, even they improved the total accuracy of the system; it fell in the accuracy paradox. The seriousness of the threat caused by the minor classes and the pitfalls of the previous efforts to address this issue is the motive for this work. In this paper, we consolidated stratified sampling, cost function and weighted Support Vector Machine (WSVM) method to address the accuracy paradox of ID problem. This model achieved good results of total accuracy and superior results in the small classes like the User-To-Remote and Remote-To-Local attacks using the improved version of the benchmark dataset KDDCup99 which is called NSL-KDD.

Purpose: The purpose of this study was to describe the using pattern of alternative therapies in the elderly. Method: 197 subjects, persons who were more than 60 years old, we interviewed. We modified and complemented Shin's(2000) instrument in accordance with purpose of this study. Data were analyzed statistically by using SAS program. Result: 1. It was shown that 66.84% of subjects have utilized one or more types of alternative therapy. 2. It was shown that the most frequently used types are acupuncture (48.83%), and ethmoid bone therapy (42.75%). 3. Acupuncture was shown to be the most satisfactory type of therapy (14.50%). 4. There was a significant difference in the use ratio by sex; female 73.47% and male 60.20%. 5. Among users of alternative therapies, the most frequent responses to each question were as follows; 1. Motive of Use - "for complete cure of symptoms" (32.31%). 2. Side effects - "no side effects" (95.97%). Conclusion: We found that elderly persons used alternative therapies more frequently than others perpulations. Diet therapy and Hand therapy were most commonly used in older people. Although the elderly use alternative therapy, they cannot place confidence in its scientific reliability. Therefore, we need to examine the effects of alternative therapy.

We demonstrate the capability of differential-phase optical coherence tomography (DP-OCT) to detect superparamagnetic iron oxide (SPIO) nanoparticles taken up by liver parenchymeal macrophages (Kupffer cells). We apply an external time-varying high-intensity focused magnetic field. Our experiments demonstrate a novel diagnostic modality to detect macrophages that have taken up SPIO nanoparticles. Magnetic force acting on the nanoparticles was varied by applying a sinusoidal current to a solenoid containing a conical iron core that substantially increased and focused the magnetic field strength ($B_{max}$ = 2 Tesla). $ApoE^{-/-}$ mice were sacrificed 2 days post intravenous injections of different SPIO doses (1.0, and 0.1 mmol Fe/kg body weight). Livers of $ApoE^{-/-}$ mice with and without injection of SPIO nanoparticles were investigated using DP-OCT, which detects tissue movement with nanometer resolution. Frequency response of iron-laden liver movement was twice the stimulus frequency. Movement was not observed in livers of control mice. Results of our experiments indicate DP-OCT is a candidate methodology to detect tissue based macrophages containing SPIO nanoparticles excited by an external focused magnetic field.

This paper presents a high-speed axial-flux machine which utilizes the idea of sinusoidal shaped pole combined with a consequent iron-pole. The target of the proposed machine is the cost reduction of the relatively expensive Samarium-Cobalt (SmCo) permanent magnet (PM) material and the torque per PM volume improvement by using sinusoidal consequent-pole rotor. The effectiveness of the proposed machine is validated by comparing it with conventional consequent-pole and with conventional PM machines using 3-D finite element method (FEM) simulations. The comparison and analysis is done in terms of back electro-motive force (back-EMF) harmonic contents, torque per PM volume and torque ripple characteristics. The simulation results show that the proposed machine is suitable and cost-effective for high-speed and high torque per PM volume applications. Furthermore, due to the consequent pole, the magnetic flux saturation and the overload current torque-capability are also presented and discussed in the paper.
