In the IEEE 802.15.4a system, they require simple, economical and low power consumption transmitter and receiver to transmit low rate data and to identify distance and location. To meet these requirements, LR-WPAN system use transmitter and receiver with simple modulation and demodulation scheme. In this paper, use PPM+BPSK modulation and windowing scheme to overcome multipath fading effect. Then we apply this channel estimation scheme to LR-WPAN system and compare performance depends on transmitter scheme. Proposed method using preamble to find channel characteristic out and we compensate distorted data with that information. Therefore we can detect signal easily at the demodulation part. Simulation result shows that performance evaluation is greater at the NLOS channel than LOS channel no matter what the receiver scheme.

The purpose of this study was to specifically explore the path leading to posttraumatic growth through self-efficacy, which is the personal psychological characteristic of adults who have experienced trauma, through cognitive flexibility and sequential mediating effects of hope. For this purpose, an online survey was conducted for adults aged 19 to 65 years old across the country with trauma experience. Among them, 316 data suitable for research analysis were analyzed. The results of this study are as follows. First, posttraumatic growth showed a statistically significant positive correlation with self-efficacy, alternative and control of cognitive flexibility, and hope. Second, the increase in posttraumatic growth was directly related to the increase in hope, and the increased hope was found to be positively related to the increased alternative and self-efficacy level. Third, in the relationship between self-efficacy and posttraumatic growth, the sequential mediating effect of alternatives and hopes was found to be statistically significant. Based on these findings, implications, limitations and suggestions of the study were discussed.

The purpose of this study is to explore the way in which the internet audience constitutes cyber culture by analysing a bulletin board system(BBS) on a historical drama, 'The World of Women'(SBS). Research findings show that the internee audience participates in a cyber space by five manners; personal participation(18.9%), critique of broadcaster's policy(11.3%), participation in a television drama community(42.1%), co-authorship(6.4%), evaluation and interpretation(21.3%). Through these kinds of participant activities, the internee audience tends to constitute a new cyber culture. Firstly, the audience seems to read 'The World of Women' by a specific way. It is the interest of a Um court lady that is characteristic on BBS of 'The World of Women'. Secondly, the internet audience constructs a new community of meaning by means of using emoticon(emotion and icon), deconstructing grammar, and remaking new signs. Thirdly, the internet audience argues their power over drama production, in other words, their ownership over the drama. Fouthly, the audience actively protests and criticise the policy of the broadcaster, especially charged service. Finally, the internet audience is likely to enjoy writing itself as a fun.

The purpose of this study was to examine what characterized the family of origin among couples who had been married just for a few years, what types of conflicts they suffered, how they tackled their conjugal conflicts, what sorts of counseling services they needed in times of conjugal conflicts and how the characteristics of their families of origin and marital conflicts affected their needs for counseling. The findings of the study were as follows: First, regarding family rules and regulations, the biggest characteristic among the families of origin of the married couples investigated was that they were most aware of rules for living. The husbands were more conscious of them than the wives. Concerning their marital conflicts in each area, their conflicts were most triggered by their own personal characteristics, followed by communal life, a third person and their own conjugal relations. Second, as for their needs for counseling, the married couples were highly willing to ask for counseling in times of conflicting with each other. Third, concerning their perception of the rules of the family of origin, the husbands were more cognizant of then Fourth, regarding connections between needs for counseling and family rules, the group whose family of origin placed stronger emphasis on rules for living felt the higher needs for counseling. It's attempted in this study to provide information about counseling for married couples, on which few domestic studies have ever focused so far, and the effort to take a micro approach toward the counseling needs of married couples made it clear that their counseling needs might be different according to their family background variables and their own marital conflicts.

Art theorists support art productions by, introducing them to the public, explaining their meanings, and playing a crucial part in the development of art. These tasks seem like their opus. Because the principles of art production and the artistic languages are quite different from the ordinaries, we need 'interpreters' who can mediate us and the artists. Art works need interpretation. And the interpretation includes not only the characteristics of the given art work, but the customs, history, and the unique qualities of the race that produced the art work. The former director of the Korean National Museum, Choi Soon-woo wrote on the characteristics of Korean art as those that stem from the poised, arbitrary, and non-elaborate state of mind. The statement of the former Director of the National Museum has its weight far greater than just a personal opinion. In fact, we encounter the same resonance of this statement over and over reproduced in the mass media. The problem lies on that it deals with not only a single art work, but the entire Korean art. And going further, this kind of remarks are already infused into every sector of our thought on art appreciation. In this paper, I argue for a re-reading of the characteristics of Korean beauty based on two reasons. First, the characteristic of art work is contemporary, thus we cannot define the characteristics of entire Korean art in a few words without the context of the period of its making. Second, Director Choi defined the characteristics that I pointed out above as 'natural' and 'nature-friendly.' Nature or being natural is not an usual word that defines the characteristics of art work, which stands for the opposite side of the nature in the binary opposition of nature/culture. To delve into these misunderstandings of Korean beauty in the popular notions of Korean art, I suggest the re-reading of three major articles on Korean art: Ryoo Jong-yeol's "Korean race and its art," Ko You-seup's reiteration of Ryoo's thesis called "Discourses in Korean Art History and Aesthetics," and Yoon Hee-soon's antithesis of Ryoo Jong-yeol titiled "Studies on Korean Art History."

In this paper, I advocate interactive model which treats science and technology as distinguishable subcultures each with their own bodies of lore and competence against the traditonal hierachical model which treats technology as applied science. For engineering science which is a component in technology as knowledge, I count design as the core part of engineering and discuss the characteristic of engineering design. I also critically assess the models of technological knowledge change, Khunian model and variation-selection model to understand the relation between science and technology. I propose a model that science and technology interaction is mediated interaction. I only outline the plausibility of this model. Industrial research is a modern form of the interaction between science and technology. I discuss Reich who focused on the broad background of industrial research and MeyerThurow who has microperspective in industrial research. The conclusion I draw from the discussion, is that through industiral research, the science-technology interaction become more structured and autonomous, and the scientists and engineers become simply patrs of the structure of industrial research rather than the personal subject.

Fast advancement and dynamic diffusion of Smart device make big change to personal user. They have been extended from consumer only watching video to prosumer recording and sharing User Created Video(UCV). With this reason, as a platform for various kind of content service. Especially, UCVs for the purpose of sharing experience are recorded from same event on limited time and space by some people. These are also produced by various cameras that has each angle similar like broadcasting videos. In this paper, we present multi-view characteristic of UCV and propose Multi-view UCV service that is watching UCVs from same event through adjusting camera angle. Through user satisfaction survey, we knew that adjusting camera angle is preferred for watching UCV including overlapping part more than linear watching.

This study was conducted under the theory of hermitage ever built from buddhist belief. Directing to hermitages within temples of Korea Jogye Order, we focused on the layout correspondence relationship among them. and 161 hermitages were the first object of the investigation. For the accomplishment of the research purpose, the general epitome and spatial specification through various literature studies, on-the-spot survey and personal communications with a lot of priests were made. As one of the basic surveys, the foundation year were thoroughly investigated, followed by the form of building, main buddha and hermitage name. The results obtained were summarized as follows : Forty five hermitages which are equivalent to twenty eight percent of total hermitages within the parish-level temples of Korea Jogye Order, were built in shilla Dynasty and twenty hermitages that are 12.4 percent of the total were constructed in Koryo Dynasty and thirty seven percent of the total were founded during both of dynasties. This fact makes us to consider that many of hermitages in those days were constructed with the simultaneity of principal temple foundation which means hermitage had responded the spirit of the times. Every hermitage has its main Buddha and this thing happened that each hermitage enshrines its main Buddha according to the thought which was developed with the Buddhism expansion and sutra that is in accordance with their own intention. .Basically a capital temple has differed in its central sanctum in accordance with resourceful sutra, and, at the same time, twenty seven in avatamsk sectenshrine for Sakyamuni as their sanction and eight for the Merciful Goddess and 42.7 percent for Chajang's hermitages. The name of hermitage not only represents its symbol but comprises the characteristic meaning of ascetic practice. 31.7 percent of the hermitages studies was found to have the names of relating to 'ascetic practice' or 'thought' followed by the 'nature' or 'environment' to 21.7 percent.
