본 논문은 사고유발기능을 중심으로 이미지의 인지적 기능에 대해 탐색적으로 고찰해보고자 하였다. 이미지의 사고유발기능이 실제 사례에서 구체적으로 어떻게 나타나는지를 알아보기 위해 꼴라쥬 미술작업을 실시하였다, 그 후 심층면접을 통해 이미지의 사고유발기능을 중심으로 이미지에 대한 연구 참여자들의 인지과정을 분석하였다. 그 결과 이미지는 대상에 주의를 기울여 더욱 면밀히 처리하도록 하고, 몰입을 증가시켜 사고를 유발하며 이를 통해 대화를 활성화하는 것으로 나타났다. 이미지의 인지적 기능에 대한 본 연구는 우리 인간 인지에 대한 이해의 폭을 확장하는데 기여할 것으로 기대되고, 특히 과학과 예술의 융합에도 유익한 통찰을 제공할 수 있을 것으로 기대된다.

단어내의 글자들을 교환하여 제시할 경우 원래의 단어로 혼동하는 현상인 글자 교환 효과에 대한 연구가 활발하다. 이는 글자교환 효과에 대한 연구가 시각단어 재인시 글자가 어떻게 부호화 되는지와 단어재인 초기과정에 영향을 주는 변인과 처리과정에 대한 정보를 제공하기 때문이다. 본 소고에서는 글자교환 효과에 대한 기존의 설명 모형들을 살펴보고, 하향적 인지적 처리를 반영하는 모형의 필요성을 논의하였다. 특히 한글 처리의 경우, 글자의 위치가 정해져 있지 않고 유동적이라고 보는 기존의 모델들과 달리 하향식으로 글자의 위치가 어휘 하위 단위인 초성, 중성, 종성으로 지정되어 있다는 가정이 필요하다. 따라서 이에 기반한 모형을 탐색하고 추후 연구방향을 논의하였다.

지식정보 사회로의 변화는 교육 패러다임의 변화를 요구하고, 이에 따라 지능형 학습과 원격 교육은 지속적인 연구 주제로서 관심을 모으고 있다. 이러한 연구 분야에서의 교수 학습 방법은 학습의 개별성, 즉, 개별 학습자의 특성에 의존하는 학습 요소 및 경로의 추출을 전제로 하며, 이는 '개별화된 추론 전략'에 대한 논의로 이어진다. 따라서 본 연구에서는 신경논리망의 확장 개념인 X-Neuronet(eXtended Neuronet)을 근거로, 학습 내용을 위계적 표상과 자체의 자기 학습(self-learning)이 가능한 학습자 인지구조체로 표현하고, 이 구조체를 이용하여 개별 학습자의 지식상태에 의존하는 추론의 개별화 전략을 설계하고, 이에 대한 타당성을 검증하였다.

Cognitive radio (CR) is considered an attractive technology to deal with the spectrum scarcity problem. Multi-radio access technology (multi-RAT) can improve network capacity because data are transmitted by multiple RANs (radio access networks) concurrently. Thus, multi-RAT embedded in a cognitive radio network (CRN) is a promising paradigm for developing spectrum efficiency and network capacity in future wireless networks. In this study, we consider a new CRN model in which the primary user networks consist of heterogeneous primary users (PUs). Specifically, we focus on the energy-efficient resource allocation (EERA) problem for CR users with a special location coverage overlapping region in which heterogeneous PUs operate simultaneously via multi-RAT. We propose a two-tier crossover genetic algorithm-based search scheme to obtain an optimal solution in terms of the power and bandwidth. In addition, we introduce a radio environment map to manage the resource allocation and network synchronization. The simulation results show the proposed algorithm is stable and has faster convergence. Our proposal can significantly increase the energy efficiency.

This study was a qualitative investigation of the process of adaptation of nutrition education programs by marriage immigrant women who completed education programs for training of food citizen leaders. Focus group interviews of seven marriage immigrant women from Vietnam, China, Mongolia and Russia were conducted and analyzed based on the Normalization Process Theory (NPT). Participants were aware of the purpose of the education program (coherence) and their confidence in organizing and reconstructing the knowledge of nutrition was increased after education (reflexive monitoring). However, they had difficulties attending long-term education programs (cognitive participation) and overcoming language barriers (collective action). Although the program was beneficial for the participants in that they could apply acquired nutrition knowledge to their everyday life as food citizen leaders, the continuous monitoring and feed-back system (management), customized application, and consideration of personal and social factors need to be developed and facilitated. In addition, various programs targeting marriage immigrant women may increase economic independence of these women. The NPT proved beneficial in conceptualizing the barriers and facilitators to implementing nutrition education. The successful implementation of nutrition intervention needs special support to overcome barriers to cognitive participation and collective action.

Purpose: This research presents a practical tool aimed at increasing collaboration between designers and marketers for effective retail space branding. We present a design-related information processing model (DIP Model), which is a schematic map that includes cognitive theories which have design applications to retail space branding. Research design, data and methodology: Through literature review and practitioner opinion survey, 43 theories pertaining to the brand communication in retail spaces were selected, and design applications of the theories were analysed through field trips to stores of global brands. Results: The DIP Model consists of two axes: the information processing axis (i.e., encoding vsretrieval) and the regulatory focus axis(i.e., promotion vs prevention). Theories related to information processing axis are theories that facilitate the encoding and retrieval of information as intended by the company. Theories related to regulatory focus axis are theories that reinforce positive cognition and prevent negative cognition regarding the brand. Conclusions: The DIP Model is developed as a tool to categorise cognitive theories that are applicable to the design of brand communication in retail spaces. As such, the model can provide a better understanding of the role of behavioural design, with the aim of building stronger brands in retail spaces.

Purpose - This study aims to accomplish three major research goals. First, it strives to change consumers' focus from peripheral routes to a central route of public service advertising related to the good health policy, without problematic effects, by influencing consumers' knowledge or involvement. Second, this study examines the elaboration likelihood model (ELM) and construal level theory (CLT). Specifically, we consider that the central route of ELM might correspond with the focal goal of CLT. Third, this study analyzes ELM through CLT. That is, ELM predicted that low involvement would take the peripheral route, and high involvement would take the central route. Research design, data, and methodology - This study consisted of three experiments. The first experiment had a 2×2 between-subject design. The subjects were university students and the research period was approximately one year. The first independent variable was the involvement of the overweight issue; this variable was measured and split by the median. The second independent variable was the temporal distance (near vs. distant future); this variable was manipulated. The second experiment also had a 2×2 between-subject design. The first variable was the involvement of cervical adenocarcinoma prevention, and was considered already manipulated by sex. Specifically, males had a low involvement of the disease, but females had high involvement. The second independent variable was priming (power vs. submissive). Power priming would induce abstract thinking, but submissive priming would take concrete processing. The third experiment had a 2×2×2 between-subject design. The first variable was cognitive depletion, and was manipulated by memorizing 9-digit numbers. The second and third independent variables were involvement and abstract thinking induction, such as prior experiments. Data were collected through questionnaires, and were analyzed by an SPSS program. Major hypotheses were tested by examining the interaction effects through ANOVA. Results - Major findings are as follows. First, even for low-involved consumers in the overweight category, distant future manipulation induced them to focus not on the peripheral route but on the central route of the public service advertisement. This result does not correspond to the typical ELM prediction. Second, under power priming, low-involved males of the cervical adenocarcinoma category focused on the peripheral route because of the induction to abstract thinking. This result replicated the first experiment, and confirmed the theoretical robustness. Third, high-involved females focused not on the central but on the peripheral route under the mixed condition of cognitive depletion and near future manipulation. Depletion consumed cognitive resources, and the processing mode of consumers changed from systematic to heuristic. Conclusions - ELM needs to be complemented through CLT in context of public service good health advertising. Specifically, the involvement of ELM may impact consumers' thinking mode (abstract vs. concrete), and the interaction effects may influence consumers' focus on advertising (central vs. peripheral route). This study's limitations were bounded subjects, limited stimuli, and somewhat weak external validity.

The rapid growth of Korean-style buffet in recent years has increased the size of corporate investment. Under this circumstance, businesses make various marketing efforts while highlighting the features and advantages of their brands. Against this backdrop, this study aims to understand which space branding has been applied to the Korean-style buffet through case studies and to propose a method of application of space branding to increase sales in an effective manner in the future. First, the research is theoretical examination and case studies with focus on the characteristics of expressions of Korean-style buffet space branding. Basically, upon completion of examining the concept and the characteristics of expressions of the Korean-style buffet and analyzing the concept of space branding, the components of space branding have been reconstructed based on preceding studies on space branding and then have been applied to each brand space. Also, the hands-on experience of the characteristics of expression of the Korean-style buffet with space branding incorporated in it and prepared a checklist via visual inspections. And then, the field surveys based on these examinations and took approach of drawing a conclusion based on the results analysis conducted by using the SPSS statistical program. Through preceding studies, the three components of space branding, that is, sensory element, emotional element, and cognitive element have been reconstructed before proceeding with this study, which has obtained five major findings as a conclusion. First, the sensory element should be given elements differentiated enough to attract consumers' attention along with a sustainable effort to have brand image imprinted in their mind. Second, in terms of emotional element, the study has found that the brand experience oriented toward interest and participation results in higher utility frequency. Third, the study has found that the cognitive element should seek consistency in communicating with consumers with focus on face-to-face contact on the display in space. Fourth, it has been found that arranging independent spaces is necessary to attract consumers' participation. Finally, the study has identified in which location area of buffet the sensory, emotional, and cognitive elements have placed a significant weight.

이 연구는 재난의 미디어 매개와 공감의 정치를 이론적으로 고찰하고, 이를 문화정치적 이슈로 새롭게 재구성할 수 있는 가능성을 모색한다. 인류의 삶과 뗄 수 없는 재난의 경험은 오랫동안 사람들이 주목하고 감정적 반응을 야기하였던 중요한 대상이었다. 하지만 현대사회는 재난의 의미를 한층 정치적인 것으로 변화시키고, 이에 대한 감정적 반응을 새롭게 재구성한다. 이 연구는 재난과 고통의 소재들이 미디어 매개 과정을 거쳐 새로운 사회적 의미를 구성해 나가는 과정에 주목한다. 그리고 미디어를 통해 매개된 공감의 경험이 바로 21세기의 미디어 환경에서 새롭게 정초해야 할 미디어 연구의 도덕적 윤리적 전환, 그리고 글로벌 시민사회의 감수성 형성이라는 문화정치적 잠재력의 원천임을 주장한다. 동시에 이 연구는 타인들이 겪는 고통의 매개 과정이 수용자들의 새로운 공적 행위를 유발시키는 중요한 계기로 기능한다는 점에 주목하고, 그것의 함의를 포착하고자 시도한다.

인과 추론은 심리학에서는 물론 최근 베이스 접근법을 취하는 인지과학자들에 의해서도 활발히 연구되고 있다. 본 연구는 인과추론에 대한 대표적 심리학 이론인 힘-확률대비이론(a power probabilistic contrast theory of causality)을 중심으로 인과 추론의 최근 동향을 개관하고자 한다. 힘-확률대비이론에서는, 원인은 결과를 일으키거나 억제하는 힘(power)인데, 이 힘은 특정한 조건하에서 통계적 상관을 통해 파악될 수 있다고 가정한다. 본 논문에서는 이 이론에 대한 초기의 경험적 지지 증거를 먼저 살펴본 다음, 베이스 접근에 기반을 둔 이론과의 쟁점을 명확히 하고, 원인은 맥락에 무관하게 동일하게 작동한다는 인과적 불변성 가정(causal invariance hypothesis)을 중심으로 한 보다 최근의 연구 결과를 소개하고자 한다. 이 연구들은 종래의 통계적 접근법으로는 잘 설명되지 않는 결과를 제시함으로써, 철학, 통계학, 그리고 인공 지능 등과 같은 인접 분야에 인과성에 대한 힘 이론을 진지하게 고려할 것을 촉구하고 있다.
