An innovation diffusion model is proposed model consists of three classes, namely, a non-adopter class, adopter class innovation-I, and adopter class innovation-II in a partially competitive and cooperative market. The proposed model is analyzed with the help of the qualitative theory of a system of ordinary differential equations. Basic influence numbers associated with first and second innovation $R_{0_1}$ and $R_{0_2}$ respectively in the absence of each other are quantified. Then the overall basic influence number (R₀) of the system is assessed for analyzing stability in the market in different situations. Sensitivity analysis of basic influence numbers associated with first and second innovation in the absence of each other is carried out. Numerical simulation supports our analytical findings.

Purpose: Due to the explosive growth and widespread use of smartphones, new business opportunities are emerging. Despite the importance of creating customer value in using smartphone applications, past studies on have mainly focused on functions or factors and specifications that influence users to use the device. Methods: This study is intended to identify how customer dissatisfaction from the use of smartphone application services affects customer sentiment and behavior. The research model is tested via a survey of 290 smartphone application users. Results: The result of this empirical study indicates that customer dissatisfaction significantly affects the user's disappointment and regret in using a service, which are subordinate values of customer emotion. The user's anger is positively associated with 'Negative word of mouth' and 'Complaint', which are subordinate values of customer behavior, but not with an intention to switch to another service. 'Regret' and 'Disappointment' are positively associated with 'Negative word of mouth' and 'Switching intention', but not with 'Making direct complaints'. Finally, customer's negative sentiments are a significant intermediary in the relationship between customer dissatisfaction and behavioral response. Conclusion: Finally, the study offers a more systematic understanding on the phasal response process of customer dissatisfaction in relation to the provision of smartphone application services.

We investigated perceptions and image analysis on scientists studying small organisms reflected in elementary student's drawing using a modified version of the Drawing-A-Scientist-Test. The participants were 530 of fifth and sixth graders consisted of 449 ordinary students and 81 science gifted students. The data were collected from associated words, images and explanatory notes depicted by students engaged in questionnaires. The results indicated that a larger number of students reminded small sized animals and/or plants as words associated with small organisms. In addition, some students depicted anthropomorphic or abstract microorganisms. In this study, more stereotypes of scientists' appearance were exhibited at sixth graders and city region group. Most of the students depicted indicators such as lab coat, glasses, scientific instruments for observing, indoor, male and young, whereas only a few students depicted collaborative work. There was statistically significant difference between girls and boys, because boys perceived male scientists only, while half of girls depicted female. More frequent research instruments and scientific captions were used when science gifted students depicted scientists studying small organisms. These results could be contributed to education on microorganisms in elementary science.

인간은 어떤 정보를 기억하려 노력하더라도, 시간이 지남에 따라 그 정보의 대부분을 잊어버린다. 반면에 인간은 사진을 보며 대부분 잊혀진 과거의 기억을 떠올릴 뿐만 아니라, 사진 속에 존재하는 특정 물체로부터 여러 단어들을 연상한 뒤, 그 연상된 단어로부터 새로운 기억을 떠올리곤 한다. 또한 이렇게 떠올린 기억으로 그 당시의 감성을 느끼기도 한다. 따라서 본 논문은 소셜 네트워크 서비스에 업로드된 사진들과 개인의 연상 단어 사전을 활용하여 사용자의 과거 회상에 도움이 되는 증강 기억 시스템을 제안한다. 제안하는 시스템에서 사용자가 특정 사진 속에 존재하는 물체를 선택하면, 그 물체와 관련된 연상 단어가 사용자에게 제공된다. 만일 사용자가 연상 단어중 하나를 선택하면, 제안하는 시스템은 해당 단어의 물체를 포함하는 다른 사진들의 목록을 사용자에게 제공함으로써, 사용자의 기억 회상을 돕고 감성을 자극할 수 있다. 본 논문에서 제안하는 시스템은 소셜 네트워크 서비스에서 보다 다양한 콘텐츠를 제공할 수 있을 것으로 기대 된다.

최근에 SNS와 온라인 매체의 영향력이 커지면서 이를 이용한 마케팅에 대한 관심이 증가하고 있다. 블로그 마케팅은 대형 포털 사이트의 키워드 검색 결과에 따라 상위 노출을 함으로서 비교적 저렴한 비용으로 마케팅의 파급효과와 정보 전달력을 높일 수 있다. 그러나 일부 특정 키워드의 검색 결과의 경우 상위에 노출되려는 경쟁이 과열될 수 있기 때문에, 블로그를 상위에 노출하기 위해서는 장기적이고 적극적인 노력이 필요하다. 따라서 본 연구에서는 블로그의 상위 노출 가능성이 높은 연관 키워드 그룹을 추천하는 새로운 방법을 제안한다. 제안된 방법은 먼저 타겟 키워드의 검색 결과에 포함된 블로그 문서들을 수집하여 단어의 빈번도와 위치정보를 고려하여 연관성이 높은 키워드를 추출하고 필터링한다. 다음에 각 연관 키워드를 타겟 키워드와 비교하여 그들의 연관성, 월간 연관 키워드 검색 량, 검색에 포함된 블로그의 개수, 블로그의 평균 작성 일을 고려하여 상위 노출의 가능성이 높은 연관 키워드 그룹을 추천한다. 본 연구에서 실험을 통하여 제안된 방법이 연관성이 높은 키워드 그룹을 추천함을 보인다.

The purpose of this study is to obtain the symbolic meaning of the priestly costume through the Bible. Based on corroborative the Bible, this thesis analyzes the costume of priest. This compares the two onyx stones on the shoulder pieces with four rows of precious stones on the breastpiece. This era falls on about from the 15th century before Christ. It was found that the breastpiece was a piece of the same multicolored linen as in the ephod, a span square when folded double. It symbolizes righteousness. It hung on the high priest's chest, supported by two golden chains attached to the shoulder clasps. It symbolizes love. On the breastpiece were twelve beautiful jewels, arranged in four rows of three jewels, each jewel symbolizing one of the tribes of Israel. The variety of jewels on the breastpiece suggests the variety of people. Urim is the Hebrew word for 'lights' and therefore would logically be associated with bright or white stones. Thummim is the Hebrew word for 'perfection'. The high priest's ephod was made of gold, and of blue, purple, and scarlet yam, and of finely twisted linen. The golden yam symbolizes faith. The robe of the ephod was made entirely of blue cloth. The blue color symbolizes an obligation and life. The robe of the ephod symbolizes calling and dignity. The woven tunic symbolizes holy duty.

This paper proposes a new semantic representation and its associated similarity measure. The representation expresses textual context observed in a context of a certain term as a network where nodes are terms and edges are the number of cooccurrences between connected terms. To compare terms represented in networks, a graph kernel is adopted as a similarity measure. The proposed representation has two notable merits compared with previous semantic representations. First, it can process polysemous words in a better way than a vector representation. A network of a polysemous term is regarded as a combination of sub-networks that represent senses and the appropriate sub-network is identified by context before compared by the kernel. Second, the representation permits not only words but also senses or contexts to be represented directly from corresponding set of terms. The validity of the representation and its similarity measure is evaluated with two tasks: synonym test and unsupervised word sense disambiguation. The method performed well and could compete with the state-of-the-art unsupervised methods.

Intensity of background noise is a factor significantly affecting both subjective evaluation of experienced stress level and associated electroencephalographic (EEG) responses during mental load in noisy environments. In the study on 27 subjects we analyzed the influence of the background white noise (WN) intensity on psychophysiological responses during a word recognition test. Electrocortical activity were recorded during baseline resting state and 40 s long performance on 3 similar Korean word recognition tests with different intensities of background WN (55, 70 and 85 dB).. An important finding in terms of physiological reactivity was similarity of all physiological response profiles between 55 and 70dB WN, i.e., none of physiological variables differentiated the two conditions, while 85dB WN resulted in a significantly different profile of reactions (higher fast beta power in EEG spectra). This condition was characterized by highest subjective rating of experienced stress, had more fast beta activity and had tendency of right hemisphere dominance, emphasizing the role of brain lateralization in negative affect control.
