A cross-cultural study was carried out in Germany and in South Korea in order to investigate the relationship between brand personality and product personality facilitating the three dimensions of personality agreeableness, excitement, and extroversion. Two pairs of shoes were prepared across categories of product function symbolic (a pair of high-heeled shoes) versus utilitarian (a pair of sport shoes). In experiments, each pair of shoes was labeled as a luxury brand ("Versace") or a casual brand ("C&A", Germany; "Migliore", South Korea) or left unlabeled. Prior to the experiments, an expert group in each country evaluated the brand personality in terms of "cheerful" (agreeableness), "honest"(conscientiousness), and "provocative" (extroversion) and the results were considered as a baseline. In Experiment I and II, subjects were exposed to two pairs of shoes labeled in one of the three ways and assessed the personality of both pairs of shoes using the personality traits, cheerful, honest, and provocative. Identical versions of the experiment were conveyed in Germany (N=56), an individualist culture, and in South Korea (N=72), a collectivist culture, and we purposed to find cultural differences in evaluating product personalities influenced by brands. The empirical results do not show any significant influence of brand personality on product personality in either cultural group (p>.05). Nevertheless, the subjects estimated the retail price of the shoes to be significantly different depending on the brands in both cultural groups (p<.001).

The InSAR (Interferometric SAR) processing steps for DEM generation consist of the coregistration of two SAR data, interferogram generation, phase filtering, phase unwrapping, phase to height conversion, and geocoding, etc. In this study, we developed the precise algorithm for phase to height conversion, including the ambiguity method taking into account Earth ellipsoid, Schw$\ddot{a}$visch method, and the refined ambiguity method suitable for the interferometric pair with non-parallel obit. From the testing with JERS-1 orbit we found that the height error by traditional ambiguity method reaches to about 40 m during phase to height conversion. The proposed methods are very useful in generating precise InSAR DEM;especially in the case of using non-parallel InSAR pair due to unstable orbit control such as JERS-1 or intentional orbit control such as Cross-InSAR pair between ERS2 and ENVISAT satellite.

In this paper, we examined the issues of the discussions on the subject of doublets. In general, as a definition, the use of doublets refer to a pair of words which have a common etymon, but also to a pair of words or grammatical morphemes that have the same meaning and similar forms of the word. In this paper, we have seen that a typical pairing word is a pair of words with a common etymology. Generally speaking, it is possible to divide doublets into subtypes depending on the identified similarities or differences in the meaning or form. The most distant type from the typical type of doublets is a pair of words that do not have a common etymon, but have the same meaning and are similar in form. The second issue about doublets is whether doublets include only words. For example, if some josas (postpositions or particles) have a common etymon, then it is noted that they can be accepted as a kind of doublets. In the case of suffixes, it may be possible to recognize the suffixes as doublets if they have a common etymon. In other words, it is not necessary to recognize the suffixes as doublets because the derivatives which are derived by the suffixes can be accepted as doublets. In the case of endings, it may be possible to recognize a pair of endings which have the same meaning and the common etymon as a doublet. Otherwise, the word forms to which the endings are combined can be accepted likewise as doublets. However, considering the fact that the endings typically in use in the Korean language may have syntactic properties, the endings should be considered as doublets rather than the words which have the endings. Finally, we conclude that there may be some debate as to whether stem doublets or ending doublets belong to a lexical item in the lexicon. It can be said that they are plural underlying forms and may be deserving of further research.

Nucleophilic addition reaction of benzenethiols (PhSH) to 1-(2-nitrovinyl) benzenes ($\beta$ NS) in the presence of triethylamine (TEA) has been studied in acetonitrile at 25 ${^{\circ}C}$. The rate is first order with respect to [PhSH], [TEA] and [$\beta$ NS]. The reaction is found to proceed with the formation of ion-pair between benzenethiol and TEA. A suitable mechanism with the formation of an adduct between ion-pair and substrate in a slow step followed by its rearrangement to 1,2-addition product in a fast step has been proposed and corresponding rate law derived. From the rate law, the rate constants for the interaction between ion-pair and $\beta$NS have been evaluated. Interestingly, in both para-substituted substrates and benzenethiols the rate increases with the electron-withdrawing power of the substituents. The positive sign of $\rho_x$ in benzenethiols has been explained. The magnitude of cross-interaction constant, $\rho_{xy}$ is small (0.08). The magnitude of the Hammett $\rho_x$ values is higher than that of the Bronsted, $\beta_x$ values for benzenethiols. The kinetic isotope effect, $k_H/k_D$, is found to be greater than unity. A suitable transition state with simultaneous formation of $C_\beta$ -H and $B_\alpha$ -S bonds involving the ion-pair and $\beta$NS in a single concerted step has been proposed to account for these observations.

We consider a surface reconstruction problem from geometrical points (i.e., points given without any order) distributed on a series of smooth parallel cross sections in ${\mathbb{R}}^3$. To solve the problem, we utilize the natural points ordering method in ${\mathbb{R}}^2$, described in [18], which is a method of reconstructing a curve from a set of sample points and is based on the concept of diffusion motions of a small object from one point to the other point. With only the information of the positions of these geometrical points, we construct an acceptable surface consisting of triangular facets using a heuristic algorithm to link a pair of parallel cross-sections constructed via the natural points ordering method. We show numerical simulations for the proposed algorithm with some sets of sample points.

A chromatographic method is used to measure interactions between dissimilar proteins in aqueous electrolyte solutions as a function of ionic strength, salt type, and pH. One protein is immobilized on the surface of the stationary phase, and the other is dissolved in electrolyte solution conditions flowing over that surface. The relative retention of proteins reflects the mean interactions between immobile and mobile proteins. The osmotic cross second virial coefficient calculated by assuming a proposed potential function shows that the interactions of unfavorable proteins depend on solution conditions, and the proposed model shows good agreement with the experimental data of the given systems.

Extending from Grossman and Stiglitz (1980), we provide an asset pricing model of a synchronously traded cross-listed pair under information asymmetry. Following Garbade and Silber (1983), the model further embraces multi-market price discovery in a dynamic framework. The implications are as follows: The price sensitivity of holdings is higher for informed traders than for uninformed traders; the largest cross-border price spread occurs in the absence of arbitrageurs; price discovery is more likely in markets with a larger population of informed traders; and parity convergence accelerates with a higher price elasticity of demand of arbitrageurs.

This study is aimed to design a priority setting algorithm necessary for evaluating and selecting interdependent R&D planning system alternatives. In case that the relationship of technology alternatives is interdependent, a relative importance as occurrence or nonoccurrence of the technology alternatives viewed from the future time varies. So, we are subject to design the evaluation process considering a cross- impact of future technology alternatives. Thus, we apply the cross impact analysis (CIA) model to consider the cross-impact among interdependent system alternatives. Also, the analytic hierarchy process(AHP) model is applied to determine the priority of alternatives by taking the pair-wise comparison among factors.

Developing turbulent flows in a rotating 90 degree bend with square cross-section were measured by a hot-wire anemometer. The six orientation hot-wire technique was applied to measured the distributions of 3 mean velocities and 6 Reynolds stress components. Effects of Coriolis and centrifugal forces caused by the curvature and rotation of bend on the mean motion and turbulence structures were experimentally investigated Productive addition of Coriolis and centrifugal forces to the outward radial direction in the entrance region of bend increases the secondary flow intensity according to the rotational speeds. However, after 45 degree of bend, centrifugal force due to the rotation of bend may promote the break down of counter rotating vortex pair into multi-cellular pattern, thereby decreasing the production rate of turbulence energy and Reynolds stresses.

An algorithm of 3-D particle image velocimetry(3D-PIV) was developed for the measurement of 3-D velocity field of complex flows. The measurement system consists of two or three CCD camera and one RGB image grabber. In this study, stereo photogrammetty was applied for the 3-D matching of tracer particles. Epipolar line was used to decect the stereo pair. 3-D CFD data was used to estimate algorithm. 3-D position data of the first frame and the second frame was used to find velocity vector. Continuity equation was applied to extract error vector. The algorithm result involved error vecotor of about 0.13 %. In Pentium III 450MHz processor, the calculation time of cross-correlation for 1500 particles needed about 1 minute.
