본 연구에서는 IT융합제품 구매 결정에 있어 잠재 구매자들이 어떻게 외부 정보를 활용하는지를 대표적 IT융합제품인 스마트폰 사례를 중심으로 살펴보고 있다. 외부 정보 원천 (external information)의 활용이 중요시 되는 이유는 스마트폰과 같은 신기술 기반의 융합제품이 더 이상 제품 사양만으로 차별화되는 탐색재가 아닌 사용자 인터페이스, 애플리케이션 이용 등으로부터 체득한 경험정보가 더욱 중요시되는 경험재적 성격을 포함하기 때문이다. 기존의 연구에서는 이러한 신기술 기반의 제품 선택에 있어 지인들이나 일반소비자들의 구전이 중요한 역할을 하는 것을 검증하였으나 온라인, 오프라인을 통해 다양한 정보 원천의 영향력을 비교 검증하는 실증 연구는 거의 없었다. 본 연구에서는 기존 연구를 참조하여 외부 정보 원천을 기업광고, 지인집단, 전문가집단, 일반소비자집단, 언론매체로 구분하고 이러한 외부 정보 원천이 어떻게 스마트폰의 구매 결정에 영향을 미치는 지를 정보 원천의 속성, 정보의 품질인식 측면에서 실증 분석하였다. 특히, 잠재구매자의 자기조절초점(self-regulatory focus)에 따라 정보 원천에 대한 속성 인식과 각 정보원천으로부터 발생한 정보에 대한 품질 평가에 차이가 존재함을 밝혔다.

The purpose of this study was to identify fashion leadership and information seeking as a part of adolescents'clothing purchase behavior study. The questionnaire was administered to 291 junior high school students. The data were analyzed using factor analysis, t-test and ANOVA utilizing SPSS/PC/sup +/. The results of this study were as follows: 1. The adolescents usually used store information seeking and consultation with friends as continuous information seeking. The adolescents usually read fashion articles in the fashion magazine more than fashion advertisements. As information seeking before purchasing, they watched store displayed or window displayed clothes the most, and then consulted with friends or family members. The degree of information seeking before purchasing was significantly different according to the number of purchasing clothes. 2. Three factors (mass communication informations, observation & personal information, and family members information) of information sources derived by factor analysis. 3. Three groups were classified as fashion leaders, fashion flowers, and fashion laggards according to fashion leadership. Girls perceived themselves as fashion leaders much more than boys did. There was significant difference among three fashion leadership groups in the number of purchasing clothes and price partially. 4. Fashion leaders seeked the continuous information and mostly used mass communication information sources and observation & personal information as information sources before purchasing clothes.

Recommender systems aim to recommend items to users by taking into account their probable interests. This study focuses on creating a model that utilizes multiple sources of information about users and items by employing a multimodality approach. The study addresses the task of how to gather information from different sources (modalities) and transform them into a uniform format, resulting in a multi-modal feature description for users and items. This work also aims to transform and represent the features extracted from different modalities so that the information is in a compatible format for integration and contains important, useful information for the prediction model. To achieve this goal, we propose a novel multi-modal recommendation model, which involves extracting latent features of users and items from a utility matrix using matrix factorization techniques. Various transformation techniques are utilized to extract features from other sources of information such as user reviews, item descriptions, and item categories. We also proposed the use of Principal Component Analysis (PCA) and Feature Selection techniques to reduce the data dimension and extract important features as well as remove noisy features to increase the accuracy of the model. We conducted several different experimental models based on different subsets of modalities on the MovieLens and Amazon sub-category datasets. According to the experimental results, the proposed model significantly enhances the accuracy of recommendations when compared to SVD, which is acknowledged as one of the most effective models for recommender systems. Specifically, the proposed model reduces the RMSE by a range of 4.8% to 21.43% and increases the Precision by a range of 2.07% to 26.49% for the Amazon datasets. Similarly, for the MovieLens dataset, the proposed model reduces the RMSE by 45.61% and increases the Precision by 14.06%. Additionally, the experimental results on both datasets demonstrate that combining information from multiple modalities in the proposed model leads to superior outcomes compared to relying on a single type of information.

This study was conducted to assess the information of food safety by college students according to mass-media reports. To accomplish this, a survey was conducted to investigate the preference and reliability, of primary mass-media sources of BSE information, and BSE-related knowledge of college students. The most common sources of media by male and female students were terrestrial television(60%), the internet(21%) and newspapers(11%) and terrestrial television(60%), newspapers (18%) and the internet(17%), respectively. The reliability of media of male students were terrestrial television(53%) and the internet(40%), while for female students these values were terrestrial television(55%) and internet(37%), respectively. In the case of male students, the primary sources of information regarding BSE were terrestrial television(54%) and the internet(38%), but for female students the primary sources were terrestrial television(57%) and the internet(37%). Both male and female students were found to have less knowledge regarding prions, SRM, and MM type genes associated with BSE when compared to the other factors associated with this disease. In addition, the important determining factors for the food purchase of male and female students both were the orders of taste, hygiene, price. The preferences for meats and the beef-alternative meats of male and female students were the orders of pork, chicken. Based on these results, greater efforts should be made to provide meaningful information regarding the safe production and distribution of meats.

The household behavior of food, clothing, and shelter in Seoul area was analyzed to determine characteristics of consumer behavior in the industrial society. Questionaires were administered to 1095 housewives to find out the degrees and types of household labor substituted by the commodities and their buying behavior. Attitudes and values concerning clothing and housing were also measured. The results of the study indicated that the degree of labor substitution by commodities in clothing related area were high, while traditional food items were relatively low. Household labors related to clothing and housing maintenance also showed increased tendency to be substituted by the commercial services. The age and educational level of housewife, and household income were found to be the influencing factors to accelerated labor substitution, which is expected to increase as the industrialization progresses. Buying behavior varied in store selection and information sources according to commodities. Marketer dominated information sources according to commodities. Marketer dominated information sources were used for foods and clothing commodities, while interpersonal information sources were used for services. Shortened clothing life cycles, and rental housing were also found indicating consumer's change in housing concept from possession to use. Suggestion were made to consumers, industries, and government based on the results from the study.

Information about the formation and filling (in 2014 to 2016) of a terminological dictionary on electronics and radioengineering and collective work (in 2017 to 2018) with a data bank "TERMIN" is presented in this article. In purpose of creating an instrument of navigating the modern scientific-technical space a net of terms with set semantic links is described. This set is based on the analysis of terms' definitions (each term is checked for inclusion in the definitions of all other terms; the definitions were borrowed from reputable reference editions: encyclopedias, dictionaries, reference books). The created model of a system that consists of different information sources, in which it (information) is indexed by the terminology of Russian State Rubricator of Scientific and Technical Information rubrics and/or keywords, is described. There is an access for the search in all these sources in the system. Searching inquiries are referred to in the language of these rubrics or formulated by arbitrary terms. The system is to refer to information sources and give out relevant information. In accordance with this model, semantic links of various types, which allow expanding a search at different modalities of query, should be set among data bank terms. Obtained links will have to increase semantic matching, i.e., they can provide actual understanding of the meaning of the information that is being sought.

The purposes of this study were (1) to segment female college students' apparel shoppers into unique apparel buying decision-making style groups; and (2) to profile for each segment in terms of personal characteristics (material values, change seeking tendency and prestige sensitivity) and fashion information sources. Data were collected through questionnaires from convenient sample of 290 female college students. As a result of cluster analysis and univariate analysis of variance, distinctive consumer decision-making style groups of consumers were identified; Value-maximizing Recreational Shoppers, Brand-Maximizing Emotional Shoppers, and Apathetic Shoppers. These three groups were compared as to the effect of personal characteristics variables and fashion information sources through univariate analysis of variance and chi-square statistics. The result showed that personal characteristics (material values, change seeking tendency and prestige sensitivity) and fashion-information sources do influence the consumer decision-making styles and that these three groups were unique in their decision-making characteristics showing that consumer decision-making styles can be a good segmentation base for apparel market.

Purpose: This dissertation is a descriptive research study analyzing the accuracy and reliability of the cardiopulmonary resuscitation (CPR) application developed in Korea. Methods: Two faculty members from the emergency medical services department and the emergency medicine department searched applications from July 1 to July 10, 2019 and selected a total of 13 applications. Twelve questions were assessed for information accuracy and three were assessed for reliability. In accordance with application types, the number and mean ± standard deviation were analyzed. The t-test was used to compare the accuracy of CPR information in accordance with information sources. Results: The results revealed the following errors: 7 cases (53.8%) identified the chest center lining from the nipple center-line as the chest pressure point; 5 cases (38.5%) did not provide information on the depth of 6 cm that should not be exceeded; and 4 cases (30.8%) did not provide advise to check respiration. When the CPR information sources were included, the information accuracy score was high; a significant difference was observed (p=.035). Conclusion: In the case of applications providing medical information regarding CPR, it is necessary to provide at least authoritarian, sources of information, and author transparency as well as continuous effort and attention.
