Online recommendation services help people search for an appropriate product among a huge assortment in stores that also minimize consumers' choice overload. People with a need for uniqueness are likely to prefer this online recommendation service based on individual needs and tastes. This study verifies the effect of consumers' choice overload and similarity avoidance in consumers' evaluation towards an online recommendation service with a focus on innovativeness and use comparability. Two-hundred consumers participated in this study and data were collected through an online survey firm. A mock retailer's webpage was created and showed six types of sneakers, which was presented as a result of product recommendation based on consumers' personal information. Data was analyzed using confirmatory factor analysis (CFA), analysis of variance (ANOVA), and regression analysis. The results show that people with a high similarity avoidance perceive an online recommendation service as an innovative and compatible service. They also perceive a high level of use compatibility for an online recommendation service, especially when it is difficult to choose a product under choice overload. Innovativeness and use compatibility of an online recommendation service increase behavioral intention. The results of this study can contribute to strategies to start online recommendation services from online retailers' websites that identify circumstances in which consumers can adopt innovative services in a positive manner.

This study aims to examine the usage of and satisfaction with neighborhood parks and university campuses and compare through the RPRS analysis of them to figure out how university campuses, as substitutive green spaces, play the role of curative environment for neighboring people. This study relied on two methods: a descriptive method of researching publications and related scholastic writings and an empirical study of researching how the park and campus has been utilized and researching whether the residents are satisfied with the currently existing space and the environment or not, and finally researching how the university campus open space as a curative environment impacts the satisfaction and utilization through reliability analysis. As a result, contribution of healing environment has a relatively high average contribution of 4 or more points, respectively. These results suggest that urban people think that a relationship between man and nature is very important in the overabundance of stress in modern society. It shows that neighborhoods are higher than university campuses in the explanatory of the Attention Restoration Theory, but the campus is higher than the neighborhood park in similarity of configuration. The result of RPRS analysis shows that the therapeutic qualities of the landscape may be very useful to evaluate a college campus open space in "the Revised Perceived Restoration Scale." The results showed that, in future studies, it will be a great help by widespread use of pre-evaluation of the characteristics of restorative environments in the planning, design and other works. To study the impact of the curative features on evaluating future research locations, the location should provide a variety of purposes and motives. At the same time, it should provide specific design ideas to design-related designers by using perceived restoration scale.

The purpose of this study is to investigate the most rational method of grouping peers to understand the impact of peer relationship on individual development of elementary school students. For the study, students at a class of the 3rd year(male) and a class of the 4th(female) year at elementary schools in Busan and Ulsan were surveyed to see the differences between various methods of classification of peer relation subgroup on the basis of cooccurence of perception data and psychological preference data. Two questionnaires were used; a questionnaire of perception and a questionnaire of psychological preference. With the perception data, value of sharing relationship was applied to classify peer relation subgroup and with the psychological preference data, interest relationship was expanded to classify peer relation subgroup of more than third party relationship. The result of this study showed that in the case of girls, there was high congruency between the classifications of peer relation subgroup by perception data and by preference data, whereas in the case of boys, there was difference between the classifications of peer relation subgroup by perception data and by preference data, which implies that boys can form a peer group even if there is psychological difference among members but girls can form a peer group only when there is psychological preference among them. Such a result shows that there is difference between boys and girls in the process of forming peer relationship. It is suggested that comparison of fitness be made between classification of peer relation subgroup by a homeroom teacher, by perception data and by psychological preference for rational classification of peer relationship among male children.

본 연구는 소비자가 다른 사람과 차별되며 특별하게 지각되고자 하는 성향을 나타내는 소비자의독특성 욕구와 의복에 대한 관심이 브랜드 인식, 브랜드 충성, 및 구매의도와의 어떠한 관계를 지니고 있는지를 밝히고자 하였다. 특히 이러한 관계에 있어 문화간의 차이가 있는지를 알아보기 위하여 한국과 미국 소비자를 대상으로, 소비자특성이 구매의사결정에 미치는 과정의 모형을 검증한 후, 두 모형을 비교 분석하였다. 자료는 설문지를 사용하여 한국과 미국대학생을 중심으로 수집되었으며, 응답이 부정확하거나 불성실한 설문지를 제외하고, 총 485부-한국 271부와 미국 214부-만이 최종 자료 분석에 사용되었다 본 연구에서 사용한 통계분석방법으로 신뢰도 검증을 위하여 SPSS 11.0을 이용하여 신뢰도 계수를 구하였으며, Prelis 2와 Lisrel 8.53으로 확인적 요인분석 및 모형검증을 실시하였다. 한국과 미국소비자의 선택친 모형을 비교한 결과, 전반적인 모형의 구조에도 차이를 보였을 뿐 아니라 각 변수간의 영향력에도 차이가 있음을 나타냈다. 소비자의 독특성 욕구의 하위차원인 '독창적 선택'과 '브랜드 충성도'의 관계는 두 그룹간의 반대의 성향을 보였으며, '비대증적 선택'과 '브랜드 인식'도 또한 한국 소비자는 정의 관계를 보인 반면, 미국소비자는 부의 관계를 나타냈다. 이와 더불어 유사성을 회피하려는 한국소비자들은 브랜드에 충성하는 경향이 있는 반면, 미국소비자들은 브랜드 인식도가 높은 것으로 나타나 두 문화간의 차이가 있음을 뒷받침하였다. '브랜드 충성도'는 두 집단 모두 '구매의도'에 상대적으로 높은 영향을 미치는 것으로 나타났다.

The emphasis of simplicity in design is because of the desire to deliver much content with a simplest way. Since in general, a simple form is outstanding in its symbolical nature and the relief of plastic beauty is easy by it, it is usually applied to a form of a symbol mark. However, in the meantime, if any local autonomous group or enterprise which has not tried to give efforts to its advertisement than they might expect and might be disadvantageous in competition. For consumers, when they experienced several, forms of simple, symbol mark, would not remember the special features of each mark. Rather, for the psychology of perception, they might remember only the formative, common features, there by grouping the marks by their common features. In this study, some symbol marks in Dobong-gu Ward Office and Wonju city were inspected, reviewed, and analized. And its is a finding that the subjects of this study could not distinguish or identify any of marks from another mark having a similar image of it: the reason is that the simplicity of a symbol mark made or allowed them to recognize it identical with the other imaged: it proves that the mistakes, defects of memory, and accumulated errors are oriented to the identical image. After all, the appearented image and perceived image are differnt. Any of symbolmarks which takes a simple form does not mean the perceived image is also simple. As a final conclusion, designers, in order to produce any of competitive symbolmarks, need to thoroughly understand psychology of gestalt.

In order to understand the processes involved in the petrogenesis and the differentiation of the primary magma spectrum, a petrological and geochemical properties were investigated for the Chonju and the Sunchang foliated granites, which are located in the southwestern part of the Okchon zone and extends up to the northwestern boundary of the Ryongnam massif as two subparallel batholiths. Major element analyses show that the Chonju and Sunchang foliated granites are classified petrologically into a weakly to strongly peraluminous or calc-alkaline, but do not fit neatly into either of the I/S-type or magnetite/ilmenite-series classification schemes for granites, although the I-type and magnetite-series characteristics seem to be predominant based on the major element chemistry. In normative compositions, the Chonju granite is petrographically evolved from granodiorite to granite, whereas the Sunchang granite is from granodiorite to quartz monzodiorite. It seems to suggest a difference of the magmatic evolution processes such as crustal assimilation and/or fractional crystallization in magma. The REE patterns of both batholiths show high similarity and strongly fractionated REE distributions which show high $(Ce/Yb)_N$ ratios and little or no Eu anomalies. These REE patterns correspond broadly to those seen in the pre-Cretaceous granitoids of Korea. Apparently, the evidences obtained from the bulk compositions strongly suggest that the two foliated granitoids were formed by partial meltings of a relatively restricted and similar, may be common, source material which contains a continental crust component having an igneous composition, and have undergone a similar magmatic differentiation processes.

The purpose of this study is to investigate the influence of parental overprotection on Korean college students' moral behaviors. To test the prediction that overprotected participants will show more immoral behaviors in moral dilemma situations, we measured perceived parental overprotectiveness and morality. Participants were 113 college freshmen. Two types of modified experimental paradigms were used to assess participants on their levels of justice-oriented and prosocial morality. Based on whether they displayed moral behavior (i.e., honest or helping behavior) or not, participants were included in either moral or immoral group. Second, the levels of perceived maternal overprotectiveness and paternal overprotectiveness were assessed using Korean-Parental Overprotection Scale (K-POS) and were compared between moral and immoral group. For justice-oriented morality, the results showed that the immoral group reported a significantly higher level of perceived maternal overprotection compared to the moral group (t = 2.16, p < .05). On the contrast, paternal overprotection was not related to participants' honesty. The results indicate that participants who experienced overprotective parental care are more likely to act immorally in moral dilemma situations dealing with justice. Meanwhile, for prosocial morality, both maternal and paternal overprotection levels did not result in significant difference between two groups. More Implications and limitations were discussed.

This paper introduces a 3D perceptual model based on JND(Just Noticeable Difference) and proposes a video watermarking scheme which is perceptual approach of adaptive embedding in 3D-DCT domain. Videos are composed of consecutive frames with many similar adjacent frames. If a watermark is embedded in the period of similar frames with little motion, it can be easily noticed by human eyes. Therefore, for the transparency the watermark should be embedded into some places where motions exist and for the robustness its magnitude needs to be adjusted properly. For the transparency and the robustness, watermark based on 3D perceptual model is utilized. That is. the sensitivities from the 3D-DCT quantization are derived based on 3D perceptual model, and the sensitivities of the regions having more local motion than global motion are adjusted. Then the watermark is embedded into visually significant coefficients in proportion to the strength of motion in 3D-DCT domain. Experimental results show that the proposed scheme improves the robustness to MPEG compression and temporal attacks by about $3{\sim}9\%$, compared to the existing 3D-DCT based method. In terms of PSNR, the proposed method is similar to the existing method, but JND guarantees the transparency of watermark.
