This study analyzed the effects of price perception and product attributes on brand loyalty and repurchase intention, and compared the differences in high- and low-priced cosmetic brands. Data were collected from female consumers in their 20s to 40s and a total of 411 responses were used for the final analysis. Findings were as follows. First, when comparing high- and low-priced brands, personal attribute and experiential attribute among cosmetic attributes, brand loyalty, and repurchase intention of high-priced showed the higher mean scores than those of low-priced. Second, all of three cosmetic attributes and P-Q/prestige were significant for high-priced brand loyalty, while experiential attribute, personal attribute, P-Q/prestige, and price consciousness were significant for low priced brand loyalty. Third, with respect to repurchase intention, all of three cosmetic attributes, P-Q/prestige, and sales proneness were significant for high-priced, while experiential attribute, personal attribute, and P-Q/prestige were significant for low-priced. Personal attribute contributed the most to high-priced brand loyalty and repurchase intention, whereas experiential attribute to low-priced. The findings of this study would be helpful to understand the purchase of high and low priced cosmetic brands. The managerial implications for cosmetic brand marketers were provided.

The quadriceps angle (Q angle) has been used to reflect the quadriceps muscle's force on the patella in the frontal plane. Previous investigations of the Q angle and it's relationship to knee disorders have yield equivocal results. The purpose of this study was to analyze the factors related to the Q angle and it's relation to other variables such as leg length, body weight, CTA (calcaneus to tibia angle), TOA (toe out angle), and pelvic width in normal subjects. The participants were 60 students (30 men and 30 women) who had no orthopedic and neurological impairments, aged from 20 to 29 years of age, with an average age of 22.1 years. Prior to participation, each subject was informed of the procedures of the experiment from a researcher and assistant researchers. The equipment used in this study were modified standard goniometer, ruler, marking pen, and Martin apparatus for pelvic width. In order to determine the statistical significance of the experiment, regression analysis, independent t-test, and Pearson correlation were used at the 0.05 level. The results were as follows: 1) It was found that the Q angle of women is greater than that of men's from both knees. 2) There was no significant difference between right and left quadriceps angle. 3) The Q angle decreased as the body weight (leg length) shifted from low to high. 4) It seems that factors related to the Q angle were body weight, CTA, and pelvic width, but there was no significant difference at the 0.05 level.

Typically everyday human life tasks involve at least two people moving objects such as tables and beds, and the balancing of such object changes based on one person's action. However, many studies in previous work performed their tasks solely on robots without factoring human cooperation. Therefore, in this paper, we propose cooperative robot for table balancing using Q-learning that enables cooperative work between human and robot. The human's action is recognized in order to balance the table by the proposed robot whose camera takes the image of the table's state, and it performs the table-balancing action according to the recognized human action without high performance equipment. The classification of human action uses a deep learning technology, specifically AlexNet, and has an accuracy of 96.9% over 10-fold cross-validation. The experiment of Q-learning was carried out over 2,000 episodes with 200 trials. The overall results of the proposed Q-learning show that the Q function stably converged at this number of episodes. This stable convergence determined Q-learning policies for the robot actions. Video of the robotic cooperation with human over the table balancing task using the proposed Q-Learning can be found at http://ibot.knu.ac.kr/videocooperation.html.

A novel zinc complex, Zn(phen)q, was synthesized from 1,10-phenanthroline (phen) and 8-hydroxyquinoline (q) as organic ligands and its electroluminescent (EL) properties were characterized. The structure of Zn(phen)q was elucidated by FT-IR, UV-Vis and XPS. The complex Zn(phen)q showed thermal stability up to $300^{\circ}C$ under nitrogen flow, which was measured by TGA and DSC. The photoluminescence (PL) of the Zn(phen)q was measured from the THF solution and the solid film on quartz substrate. The PL emission of Zn(phen)q exhibited green light centered at about 505nm. The EL devices were fabricated by the vacuum deposition. The EL devices having the structure of ITO/a-NPD/Zn(phen)q/Li:Al were studied, where 4,4'-bis[N-(1-naphthyl)-N-phenylamino]biphenyl(a-NPD) used as a hole transport layer(HTL). a-NPD has high Tg of $96^{\circ}C$ and thus makes the device thermally stable. The EL emission of Zn(phen)q exhibited also green light centered at 532nm.

The fast-growing market in wireless communications has led to the development of multi-standard mobile terminals. In this paper, a frequency-tunable active RC bandpass filter for multi-standards wireless communication system is designed using an active inductor. The conventional bandpass filter design methods employ the high order filter or high quality factor Q to improve the stopband attenuation characteristics and frequency selectivity of the passband. The proposed bandpass filter based on the high Q active inductor has an improved frequency characteristics. The center frequency and gain of the designed bandpass filter is tuned by employing the tuning circuit. We have performed the simulation using TSMC $0.18{\mu}m$ process parameter to analyze the characteristics of the designed active RC bandpass filter. The bandpass filter with Q=20.5 has 90MHz half power bandwidth at the center frequency of 1.86GHz. Moreover, the center frequency of the proposed bandpass filter can be tuned between 1.86~2.38GHz for the multi-standards wireless communication system using the capacitor of the tuning circuit.

When parental Chinese hamster ovary (CHO) cell clones that are capable of producing thrombopoietin (TPO) were subjected to high methotrexate (MTX) concentrations, clonal variations in cell growth were apparent. In the clones that had no significant enhancement in specific TPO productivity (q$\_$Tpo/)when a higher level of MTX was administered, their growth was not depressed significantly nor their cell size changed significantly. On the other hand, those clones that showed a significant-enhancement in q$\_$Tpo/ at higher a MTX dosage, cell growth was depressed initially but recovered during successive sub-cultures. Furthermore, their cell size increased, which suggested that changes in cell size may be indicative of an enhanced q$\_$Tpo/. When the enhancement of the q$\_$Tpo/ of 9 clones after a high MTX dosage was plotted against the extent of the increase of their size, there was a linear correlation (γ$^2$=0.80, p<0.001, ANOVA), which suggested that an enhancement of q$\_$Tpo/ after high MTX administration can be measured by the increase in their cell size. Taken together, our data demonstrate that the selection of amplified CHO cell clones with enhanced q$\_$Tpo/ can be done upon their increased size and growth pattern. This facilitates the development of highly productive recombinant CHO cell lines.

A new design approach for realising low-power low-voltage high-Q high-order RE bandpass filter is proposed. Based on the gyrator-C inductor topology, a 2$\^$nd/-order biquadratic bandpass filter can be realised by adding a series capacitor to the input port of the gyrator. High-Q 2$\^$nd/-order and 4$\^$th/-order fully differential RF bandpass filters operating in the 2.4-㎓ ISM (Industrial, scientific and medical) frequency band under a 2-V single power supply voltage with low power dissipation are reported.

The worthness of life of an elderly person is a subjective thing that is based on the individual's sense of values, and it depends on what he or she pursues in life. Therefore, the quality of life is a relative concept and it varies according to individual tastes and changes of values resulted from changes of social framework. The purpose of this study is to furnish information about the basic plan for the increase of Q.O.L. There are three methods used in this study. First is to understand the structure and the factors related to Q.O.L by research and documents. Second, site survey and analysis of urban and rural areas, for example Seoul and Jochiwon, and third, study the condition of the old using SPSS. The result of study to enrich the Q.O.L of the old can be categorized into two ways. First, the old themselves has to satisfy the image of the old who has a high Q.O.L. Second, the community has to support the proper environment for the old to get worth of life.

In this paper, micro cantilevers which are made of two different materials - fused quartz and single crystalline silicon - and have similar dimensions were fabricated and their mechanical Q-factors were evaluated to compare intrinsic damping properties of those two materials. Resonant frequencies and Q-factors were measured for the cantilevers having fixed widths and thicknesses, and different lengths. The measured Q-values are in a range of 64,000 - 108,000 for fused quartz cantilevers, and 31,000 - 35,000 for silicon cantilevers, respectively. Experimental results support high Q-factors of fused quartz compared to single crystalline silicon due to its good intrinsic damping properties.
