This study attempted to understand post-purchase consumer return experiences which had not received much attention in consumer behavior research. As a first step to understand return experiences from consumers' viewpoint, the study took an exploratory approach and identified themes and patterns from subjective consumer experiences. Whenever possible, attribution theory was applied to interpret the identified patterns. A total of 99 cases were collected from an open-ended questionnaire and analyzed based on a qualitative method. The reasons of product return was classified into five groups: changing mind; product defects; unsuitable products; products not expected; and for a better deal. External attribution was observed for return decisions caused by consumers' changed mind as well as by product defects. Dissatisfaction with defected products seemed to be intensified or reduced by service failure or success in the post-purchase service encounter. Consumer expectation and situations seemed to affect this process. Overall, the study supported attribution theory in the post-purchase return experience, and insights for research questions were proposed.

Although analysis of charts, which used in stock trading by distinguishing standardized patterns in the movements of stock prices, is simple and easy to use, there can be problems stemming from specific patterns being distinguished as a result of the subjective perspectives of analysts. In accordance with such problems, through the method of template pattern matching, 4 trend reversal patterns were designed and the fitness of the patterns were quantitatively measured. In cases when a stock is purchased when the template pattern fitness value is within a certain range and held for at least 20-days, the average return ratio was analyzed to be higher-with the difference being statistically significant-than the average return ratio attained from trading a stock according to the same method per the Efficient Market Hypothesis. From the results of stock trades of 2 domestic corporations to which the values of the 4 patterns had been applied based on the 4 strategies, it was possible to ascertain differences in the strategy- and pattern-dependent return ratios. Through this study, along with presenting the exceptions for the Efficient Market Hypothesis in stock trading, the fitness level of quantitative chart patterns was measured and the theoretical basis for application of such fitness level was proposed.

The purpose of this study was to provide practical data for proposing the housing environment support policy, fit for returners-to-village. For the purpose, this study focused the patterns of returners-to-village according to their experience of rural life, and their ways of settlement like planning and getting land and house. The questionnaires were answered by 91 persons who were living in Chungbuk area, and were analyzed chi-analysis on their socio-demographic characteristics according to experience of rural life, preparation of settlement and construction. The ANOVA were used to analyze their pattern of return according to experience, the period for getting house, and their satisfaction level of house size. The results were as follows. First, the returners showed differentiated tendency according to their experience of rural life, in their age, family life cycle, education level and income source after return. The experience of rural life explained the purpose of return and the living pattern after return. Direct experience group was mostly occupational farmer; indirect experience group mostly pursued good health & green life; non experience group mostly pursued green life. Second, the experience of rural life also explained differentiated tendency of returning preparation. In raising money, direct experience group mostly raised it privately but indirect or non experience group mostly used bank loan. Third, the returners mostly constructed new houses; non experience group almost constructed newly, but there were cases to utilize existing or vacant house in direct experience group, and indirect experience group favored existing house or remodeling of vacant house.

As Korean retailers are expanding their return policies, customer abuse and fraud behaviors are increasing. This study attempts to understand customers' unethical return behaviors in the Korean retailing. As an exploratory approach, the study identifies behavioral patterns of unethical returns from retail employees' perspectives. A total of 168 cases collected from 112 individual interviews with retail employees are qualitatively analyzed. Unethical return behaviors are categorized into five groups: lenting/deshopping, product defects with customer faults, unreasonable compensation demands, selfish behaviors, and problem behaviors in the service encounter. The study indicates that a variety of unethical return behaviors are observed despite a short history of return policy in Korea, and renting/deshopping and product defects with customer faults are the most prevalent return abuse behaviors.

This study investigated consumer satisfaction and dissatisfaction experiences in post-purchase product return process. As an exploratory research the study collected qualitative data of subjective consumer experiences using an open-ended questionnaire and identified and classified themes and patterns of satisfaction and dissatisfaction experiences. A total of 113 cases were categorized into satisfied experiences, unsatisfied experiences, and neutral experiences. Further, satisfied experiences were sub-categorized into kind sales associates, quick and easy return process, and services higher than expected based on sources of satisfaction in the return process while unsatisfied experiences were sub-classified into rejection of return, attitude of sales associates, and hassle of return process. In-store adaptive behaviors and intentions on future behaviors were also observed. The results indicated that service quality in the post-purchase service encounter and consumer expectation were important in determining satisfaction and dissatisfaction in the return process. Insights for research questions were proposed.

This research investigated the retired elderly who had moved to rural areas. The propose of the study was to examine the point at which there must be a difference in the patterns of a return to farming and determine the actual condition of their preparations for migration. This study had surveyed 408 seniors who wereare over 50 years old and had moved to rural areas after their retirement and analyzed the data by the SPSS PC 11.0 program. The results were as follows. First, the relevancy of U-turn, J-turn, and I-turn types that were affected by social demography was found to be dependent on their education levels and family patterns. Second, the actual conditions of the process of preparation by the types of a return to the farming were different according to the motivation and preparation fund. Nevertheless, the most important factor was the influence of their spouses. Third, the actual conditions of the process of adaptation by the patterns of a return to the farming showed no difference between the degree of efforts of the social supportand elevation of the friendship among the neighbors. The recognition of rural life problems were more acquainted towards the area of farming life. Among the 6 problem areas, leisure, health care, and economic problems were highly considered.

We study the scaling of the price fluctuation in the Korean housing market. From the numerical analysis, we show that the normalized return distribution of the housing price, P(r), has a fat-tail and is well approximated by a power-law, $P(r){\sim}r^{-({\alpha}+1)}$, with ${\alpha}{\simeq}3$ for the whole data set. However, if we divide the data into groups based on the trading patterns, then the value of ${\alpha}$ for positive tail and negative tail can be different depending on the trading patterns. We also find that the autocorrelation function of the housing price decays much slower than that of the stock exchange markets, which shows a unique feature of the housing market distinguished from the other financial systems.

″H″ type resonator has the advantage for the miniaturization of high-T7 superconducting (HTS) microstrip antenna in comparison with the conventional microstrip antenna such as rectangular type or circular type. In this paper we designed miniaturized HTS antennas using this "H"-type resonator and reported the characteristics of our antennas including return loss, bandwidth, radiation patterns, efficiency and so on. To fabricate the "H" type antenna, HTS YBa$_2$Cu$_3$$O_{7-x}$ (YBCO) thin films were deposited on MgO substrates using rf-magnetron sputtering. For comparison between normal conducting antennas and superconducting antennas, the gold antennas with the same dimension were also fabricated. An aperture coupling was used for impedance matching between 50 $\Omega$ feed line and HTS radiating patch. The ″H" type superconducting antenna showed the performance of 1.38 in SWR, 26 % in efficiency, and 13.8 dB in the return loss superior to the normal conducting counterpart.

We proposed a neural network based “left shoulder”detector. The auto-associative neural network was trained with the “left shoulder”patterns obtained from the Korea Composite Stock Price Index, and then tested out-of-sample with a reasonably good result. A hypothetical investment strategy based on the detector achieved a return of 132% in comparison with 39% return from a buy and hold strategy
