  • This paper proposed a evaluation method for individual's subjective preferred location using EEG and emotional assessment. Visual stimulus were sequentially presented a total six points(the top and the bottom of the left, the top and the bottom of the center and the top and the bottom of the right on the screen). EEG were measured from twenty subjects according to each six points. At the same time, we were executed evaluation of subjects preferred location from emotional assessment. Alpha and beta wave were measured in Fp1, Fp2, F7 and F8 location, followed by ten to twenty electrode system. Correlations and variations of alpha and beta wave from each channel were calculated and analyzed. Because of the number of subjects population under 30, we used Speareman test for a correlation analysis between alpha and beta wave. Also, emotional assessments which compose of visual sense harmony, visual sense stability, stability of position and the visibility were performed and were analyzed by average and frequency. After visual stimulus, emotional assessments were performed. From the variance analysis of EEG, beta wave from F7 was appeared statistically significant as significance probability of 0.006. Also, between alpha wave and beta wave appeared a negative correlation(r=-0.190). From the post-hoc test of F7 beta wave, location 1, 5 and 6 appeared to difference statistically significant. Emotional assessment result according to six positions showed 0.00 significance probability. Thus, location and emotional assessment appeared to influence on each other. From the average and frequency analysis of emotional assessment, location 2 showed obtained of best emotional assessment score and appeared lower beta wave than other locations. Finally, most subjects showed a preference for location 2. Through obtained results in this paper, will be helpful to about human emotional assessment and EEG research.

  • High Quality CD, OAT audio requires that large amount of data. Currently, multi channel preference has been rapidly propagated among latest users. The MPEG(Moving Picture Expert Group) is provides data compression technology of sound and image system. The MPEG standard provides multi channel and 5.1 sounds, using the same audio algorithm as MPEG-l. And MPEG-2 audio is forward and backward compatible. The MDCT (Modified Discrete Cosine Transform) is a linear orthogonal lapped transform based on the idea of TDAC(Time Domain Aliasing Cancellation). In this paper, we proposed the micro-program type vector processor architecture a benefit in MDCT/IMDCT of MPEG-II AAC. And it's reduced operating coefficient by overlapped area to bind. To compare original algorithm with optimized algorithm that cosine coefficient reduced $0.5\%$multiply operating $0.098\%$ and add operating 80.58\%$. Algorithm test is used C-language then we designed hardware architecture of micro-programmed method that applied to optimized algorithm. This processor is 20MHz operation 5V.

  • Questionnaire survey from 101 visitors and 77 specialists was carried out to establish the management plan on landscapes of the artificial structure constructed in valley within Bughansan National Park. When comparison was made between ground sill work structure and valley landscape, visitor group responded to the highest scores in valley landscape after planting of vine species in the bottom of the constructure, while specialist group responded to valley landscape after the removal of the constructure. When it made a comparison between revetment work constructure and valley landscape, visitor group responded to highest scores in valley landscape after planting of vine species in the top of the constructure, while specialist group responded to valley landscape after replacing concrete revetment by stone revetment constructure. When it made a comparison between fall work constructure and valley landscape, both groups responded to the highest scores in valley landscape after the removal of the constructure. According to the valley landscape analysis, artificial constructures built in water channel should be matched to adjacent landscape with the removal of concrete constructure. The slope of water channel should be considered to build fall work constructure.

  • 제휴 로열티 프로그램(coalition loyalty program; 이하 CLP라고 한다)이란 하나의 로열티 프로그램 안에 다수의 제휴 기업들이 참여하며, 이들과 독립된 (로열티 프로그램 운영)기업이 관리하는 로열티 프로그램으로 정의된다(Blattberg 등 2008). 본 연구의 목적은 고객의 브랜드에 대한 사전 선호 수준에 따라, CLP가 고객 충성도를 증가시키는 원인과 제휴 네트워크 안의 주체 간 인식의 전이에 차이가 있을 것임을 밝히는 데에 있다. 고객 충성도의 동기는 전환장벽(switching barrier) 관점(Balabanis 등 2006; Colgate와 Lang 2001; Jones 등 2000)에 따라 자발적인 이유(브랜드 매력도)와 비자발적 이유 (브랜드 전환비용)로 설명하였다. CLP안에서 브랜드(비선호)-CLP-브랜드(선호)간 전이효과(spillover effect)는 인지적 일관성(Aaker과 Keller 1990; Hamilton 등 1989)과 정보 통합 이론(Anderson 1981; Simon과 Ruth 1998)을 적용하였다. 연구 결과는 다음 세 가지로 학문적 실무적 의의를 갖는다. 첫째, 브랜드에 대한 사전 태도에 따라 정보처리 경향이 달라진다는 소비자 행동 연구의 견해를 CLP 제휴 상황에서 검증하였다. 고객은 브랜드 선호가 높을수록 자발적 동기를 강화하고, 반대의 경우 비자발적 동기를 강화한다. 둘째, 브랜드에 대한 사전 태도가 해당 브랜드와 연관된 주체 간 인식 전이에 긍정적 조절효과를 함을 검증하였다. 즉 선호 브랜드와 어떤 주체가 연관될 때(비선호 브랜드와 연관된 경우에 비해) 인식의 전이가 더 많이 발생한다. 셋째, 기업이 CLP가입에 대한 전략적 선택을 할 때 마케팅 목적에 따라 고려해야할 사항이 달라진다. 기업의 목적이 충성고객의 유지라면, 로열티 프로그램 자체의 보상 방식과 활용 방식 등이 고려되어야한다. 하지만 목적이 비충성고객의 확보라면, 유명 브랜드의 제휴 여부를 따져야 한다. 또한 기업은 CLP의 효과(브랜드 충성도)에 안주할 것이 아니라 그 원인을 알아야 하는데, 비선호 브랜드처럼 비자발적 동기 강화에 따른 충성도 증가는 장기적으로 바람직하지 못하다는 견해가 있다(Egans 2001).

  • The purpose of this study is to investigate consumers' knowledge and preference towards functional cosmetics. Through the beauty advisors' surveys, their own selling styles and consumer behaviors recognized by beauty advisors were analyzed. It was intended to help extend and strengthen the functional cosmetic market which has continued to grow rapidly since the approved goods under cosmetic law in 2001. For this study, the data was collected through questionnaires the professional consumer counselors confirmed from Korean women over the age. of twenty old living in the Seoul and Kyoungki areas. After pre-research was implemented on 45 women, 328 samples were analyzed as final samples. In addition,46 samples, which were collected through the questionnaires from beauty advisors were analyzed. Samples were analyzed by frequency, percentage, T-test, ANOVA using the SPSS program. The results of study were as follows: First consumers recognized whether functional cosmetics or not. According to the beauty advisor's surveys, consumers regard the functional cosmetic boundary as being wider than real functional cosmetic boundary according to cosmetic law. So, there is a gap between consumers' opinions and real law. Second, regarding the purchasing channels, the largest channel is the cosmetic store. As far as consumers are concerned the most important factor when buying cosmetics, is the suitability of their own skin types. The second factor is product quality and the third factor is price. Functional cosmetics non-experienced group are more concerned with price compared to experienced group. Related to purchasing products, functional cosmetics experienced group buy set products compared to non-experienced group buy one product. Third, the ultraviolet filter cosmetics portion is the largest in the functional cosmetics market the second largest portion is bleaching cosmetics and the third largest portion is the anti-senility cosmetics. However, Most preferred by consumers is the anti-senility cosmetics. Moreover, preference for ultraviolet filter cosmetics is the least. Finally, the level of satisfaction for functional cosmetics is high and dissatisfaction is low. Consumers feel that beauty advisors are simply pushing high priced products without recognizing the consumers' real needs. In conclusion, to develop the functional cosmetic market continually in the future, it needs to extend various products and advertise them until consumers are more aware.

  • The recent broadcasting environment has shifted to embrace multimedia and multi-channel features through terrestrial, satellite and cable media. This has multiplied the number of broadcasting programs. With the information on a myriad of programs provided to TV viewers, information overload occurs, and thus, the TV viewing environment is shifting to one where viewers cannot select programs passively. Thus, a growing need is emerging to ensure a personalized electronic program guide (EPG) to help individuals select TV programs according to their taste. This paper presents a personalized EPG that enables a purpose-oriented broadcasting service to provide personalized broadcasting programs in tune with the user's requirements and preferences.
