This study proposes new fashion brand evaluation criteria. In developing the criteria, we emphasize the following considerations: first, the object of the evaluation should be the brand rather than the products or store second, the "new" brand should be the "new" brand from the consumer's perspective finally, only fashion brands available in department store are included to examine the relationship between evaluation criteria and consumers' relationship quality perception with a department store. Our data analysis of an online survey panel sample of 537 female consumers produced six new fashion brand evaluation criteria: merchandise power, in-store communication, brand/company image, salesperson, VMD, and assortment variety. New fashion brand evaluation criteria factors include both brand attributes and store attributes. Brand-related evaluation criteria are merchandise power, assortment variety, and brand/company images, whereas store-related criteria are VMD, salesperson, and in-store communication. The associations among brand evaluation criteria, brand attitudes, and the consumers' relationship quality with department store were tested by regression analysis.

The purpose of this study was to investigate the relation of the fast food and beverage intake on sociality and anger expression of adolescents. Questionnaires were distributed to the adolescents of 599 middle and high school students in Busan. According to the results, the preference-intake frequency analysis (PEA) on fast food grid, high preference and high intake frequency were 'dukbokki', 'chicken' and 'mandu' and low preference and high intake frequency were 'ramyon', 'gimbab. PEA on beverage grid, high preference and high intake frequency were 'milk-dairy product', 'fruit juice', 'isotonic beverage' and low preference and high intake frequency were 'carbonate drink'. The intake frequency of 'pizza', 'sandwich', 'udong', and 'dukbokki' had a positive relationship with sociality. 'Hamburger', 'chicken', 'french fry', 'gimbab', 'mandu', and 'ramyon' showed a positive relationship with anger-out. The intake frequency of 'carbonated drink' had a negative relationship with anger-control, but 'green tea' showed a positive relation with it. 'Carbonate drink', 'isotonic beverage', 'coffee', and 'milkshake' had a negative relationship with anger-out. The explanation power ($R^2$) of intake of fast food and beverage on sociality was $0.019{\sim}0.038$, and 'carbonated drink' and 'coffee' had a negative influence on sociality. The explanation power ($R^2$) of intake of fast food and beverage on anger expression was $0.011{\sim}0.041$, and 'carbonated drink' had a negative influence on angercontrol. 'Hamburger', 'carbonated drink', and 'coffee' showed a positive influence on anger-out. From these results, it was necessary to develop the practical eating-out habits program on proper fast food and beverage choice for adolescents.

Strength relationships are presented through experimental data from the concrete strength tests in this study. Various strength tests such as the compressive, flexural, and splitting tensile strength and the modulus of elasticity are included. An experimental work was performed to determine the various strength characteristics for various mix designs. Three different coarse aggregates such as granite, limestone, sandstone were used and included were fine aggregates such as natural sand, washed sand and crushed sand. Also included was cement amount as experimental variable. It was confirmed that each strength value with respect to curing time is to follow a typical strength development curve. With this somewhat reliable test results various strength relationships such as flexural strength-compressive strength, splitting tensile strength-compressive strength, modulus of elasticity-compressive strength, splitting tensile strength-flexural strength were analyzed through statistics. Experimental data were well fitted to the 0.5-power relationship of flexural strength and compressive strength which has been commonly accepted. The splitting tensile strength is expected to be best in the linear relationship from the flexural strength data. Finally splitting tensile strength was found to be proportional to the 0.87 power of the cylindrical compressive strength.

This research was fairness in sport and power is how they form and change through historical discussion on the sport's doping and ran afoul of fairness Explored in match-fixing in relationship with power, the product of the problems of human desires. First, doping and exploration of power. The history of doping in sports, history as long as it existed before. Medication is ruler of the players can't or don't conform with authority between the pair formed a relationship, where, in accordance with the victory of a temptation for wealth and fame and vested interests and desire, is personal, Society and country ranging and widely is committed. In particular, power of expression is reflected well reflected in the sport in the Cold War era and, in those days was wrong thinking and practices are still truly understands the connection between doping and anti-doping. Second, match-fixing and exploration of power. Also in the history of sport as doping, match-fixing, always existed. Sport and fairness of match-fixing in relation to artificial sources, and well decide the outcome of which ended with sport, not an issue connected to gambling and other crimes, And that's another sport and bring about a vicious circle of even turn into a row. The reason for this match fixing in power part of the formation of capital and profits for the exact cause has developed that further threatens the fair sport. Thus, in fairness, and relations of power in sport doping and match-fixing is historically very meaningful and, further research and discussion is needed. Buried the materialistic values of sport doping and match-fixing, nothing is being tolerated and other researchers' power as the elements of the pie grow only by sport only No one can guarantee that only satisfied if we hold a bright future of sport.

In this paper, an adaptive predistortion scheme is proposed to compensate nonlinear distortions caused by high power amplifiers (HPA) in OFDM systems. A complex Wiener-Hammerstein model (WHM) is used to describe input-output relationship of HPA with linear dynamics. The predistorter is directly identified by complex power series model with memory, which is an approximate inverse of the HPA expressed by the WHM. The effectiveness of the proposed adaptive compensation scheme is validated by numerical simulation for 64QAM-OFDM systems.

In this paper, a new time-domain adaptive predistortion scheme is proposed to compensate for the nonlinearity of high power amplifiers (HPA) in OFDM systems. A complex Wiener-Hammerstein model (WHM) is adopted to describe the input-output relationship of unknown HPA with linear dynamics, and a power series model with memory (PSMWM) is used to approximate the HPA expressed by WHM. By using the PSMWM, the compensation input to HPA is calculated in a real-time manner so that the linearization from the predistorter input to the HPA output can be attained even if the nonlinear input-output relation of HPA is uncertain and changeable. In numerical example, the effectiveness of the proposed method is confirmed and compared with the identification method based on PSMWM.

In this paper, we obtained some supportive evidence for the long-run PPP relationship concerning the Korean Won currency. Previous tests of PPP in the bilateral exchange rates of the Korean Won rate vis-a-vis the U.S. Dollar have been exposed to the lack of power problem. We argue that their failure to find PPP relation in Korean Won rates was due to the low power of Augmented Dickey-Fuller tests or the Engle-Granger two-step tests applied to the Korean exchange rate data with short sample period. En attempting to alleviate this low power problem, we used the error-correction model test and the Johansen test for bilateral long-run equilibrium relationships between exchange rates and price indices from Korea's major trading partners. It is surprising that our evidence supporting for long-run PPP in Korean Won rate contrasts sharply with Bahmani-Oskooee, Moshen and Rhee, Hyun-Jae(1992)'s.

Development of renewable energy is promoted to achieve sustainability. So researchers are seeking and developing a new, clean, safe and renewable energy. However, solar energy is an extreme intermittent and inconstant energy source. In order to improve the photovoltaic system efficiency and utilize the solar energy more fully, and the DC power vary with module temperature, it is necessary to study the characteristics of photovoltaic P-V according to the external factors. This paper presents the analysis of characteristics of photovoltaic P-V according to the module temperature. The results show that it seems that when the module temperature increases, the DC power increases. But actually, because when the irradiation increases, the DC power increases, the result of the relationship between DC power and the module temperature of solar cell will be effects by the increasing irradiation.

In this paper, we investigate a group building based power consumption scheduling to minimize the electricity cost. We consider the demand shift to reduce the peak load and suggest the compensation function reflecting the relationship between the change of the building demand and the occupants' comfort. Using that, the electricity cost minimization problem satisfied the convexity is formulated, and the optimal power consumption scheduling algorithm is proposed based on the iterative method. Extensive simulations show that the proposed algorithm achieves the group management gain compared to the individual building operation by increasing the degree of freedom for the operation.
