Forming a network, through Social Network Services (SNS), among a group of people who share the same hobby or interests could increase the information sharing among the members at an exponential rate. Moreover, SNS users' behavior extends beyond the traditional introverted consumption behavior to a proactive behavior by owning or actively sharing product information. For firms, such proactive consumer behavior translates into marketing effects such as the word of mouth (WOM) effect. Therefore, SNSs are accepted not only as a communications channel between firms and consumers but also as marketing channel, suggesting the possibility of a new revenue source. In this context, we will explore into the factors of SNS contents which conserve firms' image and product information, and effects of the factors on consumer attitude and WOM.

Since GPS signals are vulnerable to interference and obstruction, many alternate aiding systems have been proposed to integrate with an inertial navigation system. Among these alternate systems, the vision-aided method has become more attractive due to its benefits in weight, cost and power consumption. This paper proposes a loosely-coupled vision/INS integrated navigation method which can work in GPS-denied environments. The proposed method improves the navigation accuracy by correcting INS navigation and sensor errors using position and attitude outputs of a landmark based vision navigation system. Furthermore, it has advantage to provide redundant navigation output regardless of INS output. Computer simulations and the van tests have been carried out in order to show validity of the proposed method. The results show that the proposed method works well and gives reliable navigation outputs with better performance.

This paper, reviews the characteristics of green consumers through a Focus Group Interview (FGI) method. This study shows that some remarkable changes are taking place in the lifestyles of green consumers compared with the past lifestyles of green consumers. Second, this study shows that green consumers have the correct green opinions about present environmental problems and they have a critical environmentally conscious attitude on this issue. Third, the research shows that green consumers behave environmentally (buying, use, and disposal acts) based on individual and personal standards. This study suggests (based on the research findings) methods to solve environmental problems to the government, corporations, and consumers as well as ways to increase the number of environmentally conscious consumers.

An unmanned ground vehicle can perform its mission automatically without human control in unknown environment. To move up to a destination in various surrounding situation, navigational information is indispensible. In order to be adopted for an unmanned vehicle, the navigation box is small, light weight and low power consumption. This paper suggests navigation system using a low grade MEMS IMU for supplying position, velocity, and attitude of an unmanned ground vehicle. This system consists of low cost and light weight MEMS sensors and a GPS receiver to meet unmanned vehicle requirements. The sensors are basically integrated by loosely coupled method using Kalman filter and internal algorithms are divided into initial alignment, sensor error compensation, and complex navigation algorithm. The performance of the designed navigation system has been analyzed by real time field test and compared to commercial tactical grade GPS/INS system.

The DEM (Digital Elevation Model) can be obtained from stereo image pair acquired by LEO satellite. Stereo images may consist of at least two images with different viewing angles to the imaging target for one pass or multiple passes. While each image is generally acquired from each pass in cross-track direction for multiple passes, stereo image pair in along-track direction can be acquired during one pass with attitude control capability for the pitch axis of the satellite. Single pass stereo imaging provides stereo pair image more efficiently on the fact that stereo pair image is generated with less orbit resources and less imaging time consumption. In this paper, the feasibility study result on the stereo pair image collection planning algorithm during single pass is addressed.

This Pupose of this study was to identify the type of attitudes toward money to investigate the relationship between the attitued and consumption expenditure pattern. Data were obtained from 398 household living in Seoul. Factor analysis was used for examining dimensions of attitudes toward money and cluster analysis for classifying the households by money attitudes. This study found five money attitude dimensions, i.e., the Means of Success dimension, the Means of Pleasure dimension, the Means of Security dimension, the Symbol of Anxiety dimension, and the Parsimony dimension, Based on the variation in the dimensions, five money types were identified, ie., the Means of Success, the Means of Pleasure, the Means of Security, the Symbol of Anxiety, and the Parsimony.

The objective of this study is to find the effects of consumer values on eco-friendly buying behavior. This study examines environmental attitudes and involvement as moderating variables to explain eco-friendly buying behavior of consumers. Hypotheses were developed based on Focus Group Interviews, Depth Interviews, and literature reviews. To test such hypotheses, questionnaires were distributed and collected among female adults aged 18 or above, and who are either office workers or housewives. The analysis results show that personal values, sociocultural values, and values related to ecofriendly products affect consumers in their eco-friendly buying behavior. Among those values, concern about safety and health, eco-friendly culture and trend, willingness to pay price premiums and functional effects of eco-friendly products have significant effects on eco-friendly buying behavior. Reflecting these results, business marketers must appeal to consumers with more focus on safety and health, perceived consumer effectiveness, self-monitoring, eco-friendly culture and trend, media exposure, willingness to pay price premiums, design excellence and functional effects, to implement marketing communication strategies accordingly.

This study examines how consumer attitudes toward food origin and health concerns influence beef purchasing behavior. Using data from the Korea Rural Economic Institute's food consumption behavior survey, we analyzed the frequency of purchasing domestic and imported beef. Results indicate that when not distinguishing between domestic and imported beef, perceptions of lower origin quality and higher health concerns are associated with an increase in purchasing frequency. However, such influences are statistically insignificant for imported beef. Further analysis reveals that for consumers exclusively purchasing domestic beef, these factors do not significantly impact purchasing frequency, while for consumers simultaneously purchasing both domestic and imported beef, these factors do significantly impact purchasing frequency.

연구목적 : Premenstrual Symptoms Screening Tool(PSST)를 통해서, DSM-IV상의 월경전불쾌장애(premenstrual dysphoric disorder, PMDD)에 대한 진단기준을 사용하여 월경전기증후군(premenstrual syndrome, PMS) 및 PMDD의 빈도, 기능장애, 위험인자들, 월경에 대한 태도, PMS 및 PMDD의 발현 양상 들을 조사하여 보았다. 방 법 : 서울 및 수도권의 중소도시인 수원에 소재하는 대학교에 다니는 여학생들을 대상으로 하여 월경에의 태도 질문지, PSST를 사용한 단면 조사연구를 시행하였다. 결 과 : 총 1410명에게 질문지가 배부되었으며, 그 중 1063부에 대하여 분석하였다. 응답자들은 PSST의 결과에 따라 3군[정상/경도 PMS군(n=759, 71.4%), 심한 PMS군(n=180, 16.9%), PMDD군(n=124, 11.7%)]으로 분류하였다. 각 군별로는 기본적인 역학적 변수 및 위험 인자(음주, 커피 소비, 월경통의 강도, PMS의 가족력)들의 분포에서 유의한 차이가 있었다. 응답자들을 또한 월경에 대한 태도에 따라 3군으로 구분하였다[긍정적 태도군(n=168), 부정적 태도군(n=122), 양가적 태도군(n=773)]. 심각한 월경전기 증상들을 호소하는 이들의 비율은 이 3가지 태도군 간에 유의한 차이가 있어서, 부정적 태도군은 다른 군들에 비해 더 많은 월경전기 증상들을 보고하였다. 결 론 : PMS와 PMDD는 한국의 젊은 여성들에서 널리 발견된다. 일부 응답자들은 그들이 PMDD에 대한 DSM-IV의 진단기준을 완전히 충족시키지 못하였음에도 유의한 기능손상을 보고하였다. 일반적으로, 월경에 대한 부정적인 태도는 더 많은 월경전기 증상들의 경험과 관련이 있었다.

경기도지역 학교급식 영양사를 대상으로 친환경 농산물에 대한 태도와 구매 결정요인에 어떠한 영향이 있는지를 조사하기 위해 친환경 농산물태도와 친환경농산물 구매의사 결정요인에 관한 변수간의 요인분석과 Correlation(상관관계분석), 다중회귀분석을 실시하였으며, 분석결과는 다음과 같다. 영양사들은 친환경농산물의 중요성에 관한 태도를 가지고 있으나 구입 가격에 관해서는 소극적인 태도를 나타내는 것으로 사료된다. 구매결정요인은 '충성도' 0.920, '지각된 품질' 0.791, '인지' 0.862, '브랜드' 0.801로 조사되었다. 일반사항에 따른 결과에서 영양사들은 친환경 농산물 구매결정요인 중 충성도가 가장 높았으며, 품질, 브랜드, 인지 순으로 나타났다. 친환경 농산물에 관한 태도는 친환경 농산물에 관한 구매의사 결정요인 중 품질(r=.296, p<.01) 및 브랜드(r=.350, p<.01), 충성도(r=.558, p<.01), 인지(r=.496, p<.01)와 유의미한 정적 상관관계를 보였다. 이상의 연구 결과들로 경기도지역 영양사의 친환경 농산물에 대한 태도가 높을수록 친환경 농산물에 관한 친환경농산물 구매의사 결정이 긍정적인 것으로 나타났으며, 친환경 농산물 구매의사 결정 요인 중 충성도와 인지가 친환경농산물 태도에 유의적인 영향을 미치는 것으로 나타났다. 이러한 결과를 통해 학교급식 관리자인 영양사의 친환경농산물에 대한 태도를 향상시키기 위한 방안제시가 필요하며, 친환경농산물 구매의사 결정요인들에 대한 후속 연구가 필요하다고 사료된다.
