인간은 관심을 가지고 있는 영역(ROI)에 대하여 선택적으로 주의를 집중하여 사물의 특징 을 인식하게 된다. 본 연구에서는 이러한 인간의 선택적 지각 능력을 적용한 패턴 분류 모델을 제안한다. 먼저 일반적인 클러스터링 알고리즘에 의해 입력 패턴들을 대략적으로 분류하여 참조 클러스터 패턴을 형성하고, 생성된 클러스터의 참조 패턴들을 상호 연관시켜 선택적 지각맵(SPM : Selective Perception Map)을 구성한다. 패턴 분류 및 인식 과정에서는 생성된 SPM을 입력 패턴과 참조 패턴과의 거리 계산에서 가중치로 적용함으로써 인간의 선택적 지각 능력을 패턴 분류에 반영하게 된다. 다양하게 변형된 인쇄체 숫자 및 필기체 숫자 데이터(MNIST)를 통해 실험해 본 결과 SPM을 사용한 패턴 분류 모델이 효과적임을 증명하였다.

It is well known that consumer's quality perception is strongly affected by price. Higher priced products tend to be perceived to have better quality than lower priced products although the objective product quality is the same. However, it is less known the process through which quality perception is affected by price cues. The existing literature suggests three potential hypotheses (i.e., the selectiveprocessing hypothesis, the selective interpretation hypothesis, and the representativeness heuristic hypothesis) that explain the underlying processes of the price-induced quality perception. The current research tests among the three competing hypotheses and also examines the role of consumer knowledge as a moderating factor. An experiment was conducted to test the moderating role of the knowledge in the price-quality relationship and to investigate the underlying process. The results indicate that theinfluence of price on perceived quality differs between novices and experts. Expert consumers' quality perception is not significantly influenced by price and this finding is consistent with the extant literature. On the other hand, novice consumers' quality perception is affected by price and the tests on the underlying process support for the representativeness heuristic hypothesis. Novice consumers assess that a high-priced brand should have good product quality due to the belief that high (low) price brands represent better (worse) brand quality and such a representativeness heuristic occurs without involving selective attention or selective interpretation price-consistent information.

The objectives of this study were to assess the current practices of implementing selective menus and to identify the perception of foodservice manager and customer on selective menus for hospital foodservice would be fulfilled. Two types of questionnaires for hospital foodservice managers as well as customers were developed. Questionnaires were distributed to managers of 8 hospital foodservice department and 317 customers of patient meal service, and 6 managers and 139 customers were responded. The data were analyzed using frequency and t-test. The results of this study can be summarized as follows : 1. In hospital foodservice operations, the selective menu pattern was first introduced by L hospital on June 1994 in Seoul and recently 8 hospitals were currently implementing selective menus. But using rate of selective menus by patients were relatively low(23.2%), ranging from 15% to 32%. 2. Customers' needs for selective menus were rated significantly higher in the group of patients(4.24/5) who chose the selective menus than their counterpart(3.88/5). 3. The main reason not choosing selective menus was identified by patients as 'not knowing the implementation of selective menus'(52.6%), inconvenient factors in using selective menus for customer were also identified as orders : 'lack of nutrition information on menu item'(38.6%), 'complexity in procedure'(29.8%), and 'lack of menu variety'(26.3%). However managers considered 'managerial burden' and 'limited human resource' as main obstacle to implement the selective menu pattern. 4. Customers indicated 'variety of menu', 'active public relations' as effective methods to enhance using rate of selective menus, however, foodservice manager indicated 'variety of menu'(50%), 'improvement of quality'(16.7%), and 'simplicity in procedure'(16.7%). Based on the results of this study, following recommendations have been suggested : Managers in patient meal service should recognize customer needs for implementing selective menus and pay more attention in implementing selective menus and activating this program. For more effective implementation of activating selective menu program, the foodservice department should establish action plan on 'active publicity work', 'simplicity in procedures', 'variety of menu' and 'improvement of quality'. Especially nutrition informations on meals should be provided for customers in order to elevate participation rate.

본 연구는 정상 청력인에서 시간 변화 (i.e., 압축과 확장)와 선택적 단어 강조법이 문장인지도에 영향을 미칠수 있는지를 평가하였다. 정상 청력을 지닌 성인 20명이 연구에 참여 하였다. 자극음으로 한국표준 일반용 문장표(KS-SL-A)가 사용되었고, 문법적으로는 적절하지만 의미론적으로는 변칙적이고 무의미하게 재구성한 후, 여성 화자에 의해 녹음하였다. 시간 변화는 7단계 (e.g., ${\pm}60%$, ${\pm}40%$, ${\pm}20%$, 0 %)의 압축 및 확장으로 조절하였다. 이 때 선택적 단어 강조법 (i.e., 문장 내에서 특정 단어를 강조)의 효과를 보기 위하여 모든 대상자들에게 2주 간격으로 두 번 검사를 시행하였다. 연구 결과 1) 시간 변화에 따른 문장인지도 정반응률은 60 % 압축 조건에서만 통계적으로 유의하게 낮았다. 2) 선택적 단어의 강조 유무에 따른 문장인지도의 정반응률은 유의한 차이가 없었다. 그러나 6 ~ 7개의 어절로 이루어진 장문장의 자극음을 사용할 경우, 40 % 압축 조건에서 단어가 +6 dB 강조되었을 때, 유의하게 정반응률이 향상되었다. 3) 성별에 따른 문장인지도의 정반응률은 유의한 차이가 없었다. 본 연구의 결과는 조금 빠른 시간 압축과 선택적 단어 강조법을 함께 사용했을 때가 시간 확장만 사용하였을 때보다 문장을 이해하는데 더 효과적임을 시사하고 있다. 그러나 후속 연구에 의한 표준화 자료가 동반되어야 하겠다.

This research is to classify psychological risk perceptions in purchases process at counterfeit at fashion luxury brands, into a risk perception on purchase activity itself and a risk perception on the post-purchase situation, and to analyze types and characteristics at risk reduction behaviors to reduce each risk perception. In this research a qualitative method was employed, and research-related data were collected and analyzed through in-depth interviews. Results were shown that risk reduction behaviors at psychological risk perception on purchase activity itself included rationalization of purchase, accompanied purchase, reduction and discontinuance of purchase, and that risk reduction behaviors of psychological risk perception on the post-purchase situation included information search, establishment of selection criteria, establishment of marginal limit, selective purchase, planned and compared purchase, and reduction and discontinuance of purchase. Previous researches suggested brand loyalty, selection of famous brands, utilization of information agents by marketers, pre-purchase usage and guaranteed purchase, but these risk reduction methods were not utilized, this probably being interpreted as a result of characteristics of counterfeit. In addition, risk reduction behavior of one type tended to reduce risk perception of several other types, and risk reduction behaviors of various types were utilized to reduce a certain type's risk perception. Not only types of risk perception but also levels of risk perception appeared to have exerted influence to risk reduction behaviors.

This study was designed to investigate the feasibility of utilizing an adaptation for selective elicitation of tactile sensations by means of transcutaneous electrical stimulation. We conducted the first experiment to investigate how the stimulation frequency affected the adaptation. Twenty healthy subjects participated in the second experiment to confirm our proposal that the perception intensity of the low-frequency vibration can be enhanced after a high-frequency adaptation, and vice versa. It was found that (1) a low-frequency stimulation did not adapt the nerve afferents responsible for the high-frequency vibration, (2) a high-frequency stimulation affected the nerve afferents responsible for the low-frequency vibration, but adapted to the pressure sensation more intensely, and (3) more than 62% of the subjects reported a more clear selective sensation after the adaptation had lessened or depressed the unwanted sensation. The observations showed that adaptation of the nerve afferent could be utilized for selective elicitation of tactile sensations.

The purpose of the present study was to investigate the differences in purchase behaviors, buying motives of secondhand clothing and the perception toward secondhand clothing products among the groups as determined by their gender and age. Data were collected by a pilot test and the final questionnaire survey administered to 450 subjects in the age range from 20 to 59, living in Seoul; 430 were used for data analyses. The results showed that 3 factors for buying motives (distinction, affordability, and quality & attractiveness) and 2 factors for perception toward secondhand clothes (positive and negative perceptions) were formulated. Women tended to buy more secondhand clothing products for themselves as well as their family, and put more importance on most of selective criteria than men did. The young were more likely to have negative perception and to buy at diverse places. Those having experiences of buying secondhand clothes showed more positive perception on such products. It is expected that this study provides basic information needed for secondhand apparel companies to develop their marketing strategies to increase customer satisfaction.

The purpose of this study was to investigate the relationship between perceived risk and purchasing behavior of clothing gift among adult women. Data were collected from 258 adult women reside in Kwangiu who have ever been to purchase clothing gift during recent six months using a qusetionaire. Frequency Analysis, Factor Analysis, Correlation Analysis, T-test were carried out in the collected data. The findings were as follows; 1. The types of risks that respondents perceived when they purchased clothing gift were identified as practical-economic risk, the social-psychological risk, the fashionable risk and the time-refunding risk. 2. The higher the self-satisfaction motivation was, the higher the social-psychological risk and the higher the practical motivation was, the higher the practical-economic risk (P<.001). 3. The degree of the perceived risks of the Low Planning Group was higher than that of the High Planning Group (P＜.001). 4. When the respondents perceived social-psychological risk high, they considered brand, fashionability, and store type as more important selective criteria and when the practical-economic risk perceived high, practicality, store service were conidered more important (P＜.05). 5. When respondents perceived social-psychological and fashionable risk high, they used both personal information and non-personal information high (P<.01).

This exploratory study examines the critical factors associated with news consumers' perception of information overload and news consumption patterns. An online survey was conducted with Qualtrics panels (N = 1001). The demographics and three antecedent factors of perceived information overload were considered including the frequency of news access through multiple media platforms, level of attention to news, and interest in news. Three news consumption patterns were investigated as possible consequences of perceived information overload: news avoidance, selective exposure, and willingness to pay for news. The results of hierarchical regression analyses revealed a meaningful distinction between general and news information overload. Overall, news consumers who paid more attention to news through newer media/platforms/devices perceived higher levels of information overload, were more willing to pay for the news, and often avoided news or selectively exposed themselves to certain sources of news to manage news information overload.
