Purpose - This study aims to illustrate the relationship between demographic factors and perceived risk types, supposing that Korean customers tend to postpone buying or hesitate to purchase the new version of hand sets, because of an early buying risk. Research design, data, and methodology - In addition to existing perceived risk types, the authors introduced an early buying risk. In order to measure each variable, also, the study has employed a five-point Liker-scale. To increase research reliability and validity, the research adopted an exploratory factor analysis, a confirmatory factor analysis, and one-way ANOVA. Results - First, there were statistically significant differences between financial risk and the group. Second, there weren't any statistically significant differences between the group means among the four perceived risk types (Performance Risk, Social Risk, Psychological Risk, and Physical Risk) and 4 factors (Gender, Age, Job, and Education). Lastly, job is apparently differentiated from others (Gender, Age, and Education). Conclusions - The authors found that customers regarded an early buying risk as one of the important perceived risk types, when purchasing a hand set.

Synaptic plasticity, which is a long lasting change in synaptic efficacy, underlies many neural processes like learning and memory. It has long been acknowledged that new protein synthesis is essential for both the expression of synaptic plasticity and memory formation and storage. Most of the research interests in this field have focused on the events regulating transcriptional activation of gene expression from the cell body and nucleus. Considering extremely differentiated structural feature of a neuron in CNS, a neuron should meet a formidable task to overcome spatial and temporal restraints to deliver newly synthesized proteins to specific activated synapses among thousands of others, which are sometimes several millimeters away from the cell body. Recent advances in synaptic neurobiology has found that almost all the machinery required for the new protein translation are localized inside or at least in the vicinity of postsynaptic compartments. These findings led to the hypothesis that dormant mRNAs are translationally activated locally at the activated synapse, which may enable rapid and delicate control of new protein synthesis at activated synapses. In this review, we will describe the mechanism of local translational control at activated synapses focusing on the role of cytoplasmic polyadenylation of dormant mRNAs.

The purpose of this study was to find out the relationship between consumer's perceived risks and return behavior on internet clothing shopping. Questionnaires were distributed to the consumers, total 517, males and females, aged from 20 to 39, who had experience of clothing purchasing through internet shopping malls. The results showed that consumer's return factors related to the perceived risks on internet shopping process. The results were as follows. First, factors of perceived risks in internet clothing shopping were categorized into product performance, account-related, delivery, economic, and social psychological risk. 5 consumer types of perceived risk were segmented by low-perceived risk group, product performance/delivery-perceived risk group, account related-perceived risk group, harmony with oneself/account related-perceived risk group, and harmony with others/economic-perceived risk group. Second, the consumer's perceived risks on internet shopping process affected one's return behavior. The factors of return was differentiated on the types of consumer's perceived risk. The relation between consumer's perceived risks and return behavior on internet clothing shopping was significant. Therefore company had better draw various strategies to manage consumer's perceived risk, in order to reduce the returns and improve consumer's satisfaction.

The genetic polymorphism and relationship among 14 Zelkova serrata registered as the natural monument in Korea were investigated using RAPD markers. N-J tree indicated that individuals in Kangwon-do were clustered and those in Yangam-gun and Damyang-gun of Chollanam-do were done closely. However, all the others were not agreed with the geographical distribution. Maybe this discordance was resulted from their movement by human being than any biological factors. The polymorphic percentages among individuals were from 77.8 to 100. From the high polymorphism, it was supposed that existing natural monuments were independently originated in the ancestors of long differentiated populations.

The examples of developing a building site after the Woongjin period are mainly found in temple sites, tile-roofed building sites of unidentified features, and palace remains including the pavilion site with the river in the front(임류각지) inside the Castle of Gongsan, Gongjoo. In case of the Hanseong period, a glimpase of the features has gained in Poongnab mud castle and Mongchon mud castle, but the excavated relics are not yet enough to make some date out of them. After the Woongjin period of Baejae, the earth-ramming development method was used mostly to construct a building site, which is divided into horizontal and slant raising of the ground level. Both are used simultaneously, but there are the significant differences in the way of raising the ground level between them. Particularly, in case of the Wanggoong-ri relics in Iksan, the ground level was raised in a narrow line slantly, which is differentiated from other slant raising of the ground level, and its time of construction also is after that of others. In addition, the board-building development method used for narrow space is usually found in the remains since the seventh century. However, there are not enough the relics of Baekjae to reveal the whole aspect of building site development. It should be studied later through the subsequent excavation and research.

The purposes of this study are to classify housewives based on their perception of benefits sought of preschool child education commodity and to identify the characteristics of each type. For empirical analysis, the data for this study were collected from 400 full-time housewives with preschool child living in Seoul. The statistical methods adopted fur data analysis are cluster analysis, one-way ANOVA, Duncan's multiple range test and discriminant analysis. The major findings of this study are as follows : First, four housewives' types can be categorized by the level of those 3 dimensions. The name fur the types was given as 'sticking to one's belief type', 'taking importance to early stimulation type' 'conforming to and imitating others type', and 'believing blindly in education commodity type'. Second, the result of discriminant analysis shows that 'housewives' education level and their education-related values' element was the most crucial in classifying the housewives, and 'considering child's characteristics and educational home environment' element was the next. The results of this study suggest several implications fur the education of parents with preschool child. Parents' education programs differentiated by the objects and the problems should be developed : which are suitable for each housewives' type.

This study was performed for 235 caddies of 5 membership golf clubs in Jeonnam area to find out their attitude and usage, satisfaction and preference on uniforms $1^{st}\;to\;15^{th}$ February 2007. The result of the study could be summarized as fellows. First, 69.7% of them affirm in the inquiry of 'to feel belong' and 'to tell from others', but they showed low affirmation in other inquiries. In the case of satisfaction of wearing uniforms, they show low satisfaction in most categories such as design, color, materials, activity, and symbol. Second, the most favored color coordination is the two color coordination in the upper and bottom uniform, and the fevered design pattern is the no-pattern one with single color. The favored uniform constitutes a jacket and a trouser in spring through fall, and a parka long enough to hip line, a polo neck, a vest, and a trouser in winter Third, activity is the most important considering factor in the choice of uniform and is also the most improve-wanted factor in the presently wearing uniform. The most important factor in the characteristic of material is absorption of sweat, but there is especially high dissatisfaction in absorption. It shows that there are demands of functional design considering caddies' working environment and activities. Differentiated from other normal uniforms, the uniform should be improved for caddies to develop their specialty and to feel wearing satisfaction.

This research recognizes the importance of hotel and regular traditional restaurants contributing to tourism industry that goes along with demands of an era that considers traditional culture important, and focuses on searching for possibility by proposing direction of designs that traditional restaurant uniforms should aim. To achieve this study goal, by surveying the problems & preferences of the current uniform, over 60% of both the attendants & customers expected an improvement in the uniform. Most of the subjects wanted the improvement in design, followed by the improvement in functionality. Over 80% preferred traditional design or modernized design where traditional aspects were applied. Also, over 70% preferred a design where a pattern was applied. Among the patterns, over 80% of the subjects said that they prefer traditional patterns or modernized patterns where traditional aspects are applied. We admit that there are some limitations on this study, such as insufficient analysis & study on the attendants' action and their uniform, as well as limitations on restaurant selection. However, Through the study we expect that the Korea uniform can be differentiated from others, achieving World-class competitiveness.

For the underwater wireless sensor networks, we propose the packet transmission method which distinguishes more important packet than others. Because the ocean underwater transmission environments are extremely unstable, we use SON(Self Organizing Network) techniques to adapt to the constantly varying underwater acoustic communication channels and randomly deployed sensor nodes. Especially we suppose two kinds of packets which have different priorities, and through the simulations we show that high priority packets arrive at the source node faster than lower priority packets with a proposed scheme.

This study focuses on design method of the memorial park for the improvement of the funeral culture in Korea. Through the comparative analysis between domestic and overseas cases, this study articulates the issues that should be taken into consideration in the design of memorial park and categorizes such issues in accordance with their types. According to comparative analysis, the characteristics of domestic and overseas cases can be summed up as follows. Most of the overseas cases can be characterized with creative concepts and images in their designs because designs are not only based on the issues articulated in this study but also show a various patterns issue by issue. On the other hand, domestic cases do not show differentiated images from others, which results from the uniform design that disregards the issues articulated in this study. The memorial park for the future should be designed to play a significant role of citizens´ park under the new conceptual framework. Therefore, the issues articulated from this study should be reflected in the design of memorial park. In addition, various types by issue should be introduced to design of memorial park. The purpose of this study is to suggest basic criteria for the design of future pattern, not simply to compare the strength and weakness of different types. This study has a limitation in that it does not offer comprehensive information of what types of memorial park will coincide with the Korean's collective sentiment. Therefore, impending tasks of further researches should involve the opinion and preferences of citizens concerning the design of memorial park.
