These videos are characterized by several appealing features, including brief duration, diversity, fragmented structure, immersive experience, and algorithmically personalized content. This study aims to investigate how algorithm-driven consumption and immersive engagement with short-form video content affect users’ information processing mechanisms through an online experimental design.

최근 차세대 무선통신인 5G가 일상 생활에서 실용화되면서 다양한 분야에서 많은 변화가 이루어지고 있다. 그러나, 5G의 향상된 속도와 지연 시간이 개선되었지만 여전히 사용자 보안에 대한 개선이 요구되어 지고 있다. 본 논문에서는 5G의 이질적인 환경에서 사용자의 프라이버시 정보를 효율적으로 보호하기 위한 다중 그룹의 정보 관리 기법을 제안한다. 제안 기법은 서로 다른 이기종의 장치에서 생성되는 사용자의 프라이버시 정보를 서로 다른 그룹에서 연계 처리할 수 있도 록 연계 정보를 클러스터링하여 분산 관리할 수 있도록 하는 것이 목적이다. 제안 기법은 주기적으로 사용자의 프라이버시 정보를 동기화하여 사용자별 프라이버시 정보를 가상의 공간에서 독립적으로 처리한다.

With the recent commercialization of the next generation of wireless 5G in everyday life, many changes have been made to organizations, industries and businesses of various sizes in various fields. However, although the improved speed and latency of 5G has improved, improvements in encryption, authentication and privacy are still required. In this paper, multiple groups of information management techniques are proposed to efficiently protect users' privacy in the heterogeneous environment of 5G. The proposed technique aims to allow distributed management of users' privacy links by clouding the privacy information generated by different heterogeneous devices to efficiently interface with different groups. Suggestion techniques process user-specific privacy information independently in a virtual space so that users can periodically synchronize their privacy information.

A review of the studies on infant learning, stimulus preferences. and habituation supports the following assertions. Firstly, the finding that a very young infant is capable of control of his basic responses if required implies that his ability for differentiating critical stimulus features is sufficiently adequate to be utilized in response adaptation. Secondly, results from both stimulus preference, and habituation studies indicate that before the infant is able to manage his motoric response, he is extensively engaged in stimulus differentiation and information processing. Thirdly, evidence from current habituation research using more elaborate procedures suggests that attentional processing under habituation is more than a single phenomenon, possibly involving multi-level processing. And lastly, existing data support Jeffrey's hypothesis of serial habituation as a mechanism for perceptual development.

This study investigates the psychological and cognitive mechanisms underlying This study investigates the psychological and cognitive mechanisms underlying political rumor dissemination on SNS in South Korea by synthesizing three political rumor dissemination on SNS in South Korea by synthesizing three theoretical frameworks: framing, the third-person effect (TPE), and the theoretical frameworks: framing, the third-person effect (TPE), and the elaboration likelihood model (ELM). We conducted an online experiment (N=800) elaboration likelihood model (ELM). We conducted an online experiment (N=800) examining how different rumor frames (character vs. competence) influence examining how different rumor frames (character vs. competence) influence rumor dissemination. The results demonstrate that participants exposed to rumor dissemination. The results demonstrate that participants exposed to character-framed rumors, compared to competence-framed ones, were more character-framed rumors, compared to competence-framed ones, were more likely to exhibit TPE, perceiving others as more susceptible to the rumor’s likely to exhibit TPE, perceiving others as more susceptible to the rumor’s influence than themselves. Path analysis revealed significant indirect effects, with influence than themselves. Path analysis revealed significant indirect effects, with character framing influencing SNS dissemination intention through TPE and both character framing influencing SNS dissemination intention through TPE and both peripheral and central routes of ELM. These findings advance our theoretical peripheral and central routes of ELM. These findings advance our theoretical understanding of rumor dissemination by revealing the complex interplay understanding of rumor dissemination by revealing the complex interplay between message framing, perceived influence on others, and dual information between message framing, perceived influence on others, and dual information processing routes. The study also enriches the literature on political rumor processing routes. The study also enriches the literature on political rumor framing effects by demonstrating how different trait qualifications shape sharing framing effects by demonstrating how different trait qualifications shape sharing behavior on social media, suggesting that character-framed political rumors may behavior on social media, suggesting that character-framed political rumors may be particularly influential in digital environments.

Individuals may seek and read other’s opinions, or they may want to interact with others after participating in virtual communities. Information, opinions, or advice in virtual communities may drive individuals to make decisions. However, the value of the information may vary from person to person. Individual perceptions and experiences will influence how she or he forms different evaluation for the same content of information. Our study thus investigates how individuals process others’ opinions on stock message boards for their investment decisions, particularly when they have different levels of investment return. Their gain/loss of wealth may influence investors’ information processing behavior. Behavioral finance literature argues that self-attribution bias influences an investor’s learning process. The self-attribution bias suggests that investors who lose money after basing their decisions on other’s opinions may subsequently value other’s opinions less, while those who profited from investments after using other’s opinions may overestimate their own investment-related abilities. In the context of online stock message boards, we investigate the influence of investment returns on investors’ information processing behavior, starting with an exploration of how they attribute their success or failure to either themselves or other investors on stock message boards.

In today’s convergence era, the knowledge integration capability of knowledge workers is crucial for developing new products or services. This study investigates the impacts of social and technical factors on employee’s knowledge integration capability and knowledge creation. The results of structural equation modeling indicate that employee’s knowledge integration has strong relationship with their knowledge creation. The results also suggest that employee’s thinking ability, knowledge complexity, and expertise are the significant predictors of their knowledge integration. Interestingly, the technical factor, i.e., supportive technologies, was not significant in influencing employee’s knowledge integration.

The present study tested whether adult Korean learners of English are able to immediately integrate verb-specific structural information (i.e. subcategorization restrictions imposed by individual verbs) as they read sentences in English. Seventeen native speakers of English and 22 Korean learners of English participated in an eye-tracking experiment, in which they read English sentences that contained a wh-dependency between the head NP and the verb of a relative clause. The relative clause verbs consisted of three types that varied in terms of subcategorization properties: transitive verbs that take an NP complement more often than a PP complement, transitive verbs that take a PP complement more often than an NP complement, and unaccusative verbs that are strictly intransitive. The results suggest that whereas native speakers use verb subcategorization information in making initial parsing decisions regarding wh-dependency formation, Korean learners are only able to integrate the information in later stages of sentence processing. Possible accounts of this discrepancy in the time course of verb information integration are discussed.

최근에 정밀 추적이나 타격 등의 군사 목적으로 UAV를 활용하는 연구가 매우 활발하게 진행되고 있다. 앞서가는 비행체를 추적하기 위해 후방에서 촬영한 영상을 활용하여 롤, 피치, 요와 같은 그 비행체의 자세 정보를 추정하는 기존의 연구가 진행되었다. 본 연구에서는 기존의 영상처리기법을 이용한 연구에 칼만 필터를 적용함으로써 자세 정보를 더욱 정 밀하게 추정하는 방법을 제시한다. 영상처리를 사용해서 추정한 비행 자세 데이터에 칼만 필터를 적용함으로써 기존의 방 식에서 발생했던 자세 각도의 추정오차 범위를 크게 줄일 수 있었다. 시뮬레이션 실험을 통해서, 칼만 필터를 적용할 경우 비행체의 자세 정보를 더욱 정확하게 추정할 수 있음을 확인할 수 있었다.

In recent years, researches utilizing UAV for military purposes such as precision tracking and batting have been actively conducted. In order to track the preceding flight, there has been a previous research on estimating the attitude information of the flight such as roll, pitch, and yaw using images taken from the rear UAV. In this study, we propose a method to estimate the attitude information more precisely by applying the Kalman filter to the existing image processing technique. By applying the Kalman filter to the estimated attitude data using image processing, we could reduce the estimation error of the attitude angle significantly. Through the simulation experiments, it was confirmed that the estimation using the Kalman filter can estimate the posture information of the aircraft more accurately.

Introducing the concept of construction safety in the design/planning phase can improve the efficiency and effectiveness of safety management on construction sites. In this sense, further improvements for safety can be made by designers’ involvement in the elimination or management of design-related hazards in addition to contractors’ own efforts, as known as Prevention through Design (PtD). However, this idea has not been well materialized in construction practices due in part to the lack of a PtD tool that allows designers to automatically check and evaluate designs in terms of worker safety. The paper addresses this issue by designing and testing an automated compliance checking framework that extracts information relevant to design-related hazards from regulatory documents and maps it to each of related design components using Natural Language Processing (NLP) and Building Information Modeling (BIM). The proposed framework has two key functions: 1) automatically extracting machine-readable regulation information relevant to design-related hazards using NLP techniques; and 2) automatically mapping such information to corresponding design components in a building information model, enabling the visualization of hazards. How all these components work to automatically display design-related hazards and relevant regulatory information is illustrated with a three-story building, focusing on fall protection. The proposed framework successfully extracted regulation information from textual documents with about 90% of precision and recall rates. It also correctly identified all the hazards in the case study model. The automated framework is expected to facilitate safety design review by improving designers and contractors’ proactive responses against design-related hazards

Background/Objectives: Recently, as the usability of IoT devices increases, the kinds of information processed by IoT devices are also diversifying. For this reason, research to ensure the high-speed processing and integrity of information generated from IoT devices continues steadily. In particular, research using various hash techniques is actively underway to minimize IoT information errors. Methods/Statistical analysis: In this paper, instead of sending IoT information directly to the server (data center), we propose an AIoT technique that allows AIoT to pre-analyze and delivers only important information. Findings: The proposed technique allows easy control of IoT information operation after analyzing patterns of information collected from IoT devices to extract and analyze large amounts of IoT information. Furthermore, the proposed technique minimizes network delay as well as minimizes server (data center) processing and analysis time by reducing network traffic that can occur when information collected from numerous IoT devices is delivered to the server (data center). Improvements/Applications: AIoT, IoT information, Extract and Analysis, Artificial, Depp Learning, hash techniques Performance evaluation compared the storage efficiency of servers and the number of transactions of IoT information sent and received per second between IoT devices and AIoT devices while varying the hash length of IoT information from 16 bits to 128 bits.

본 연구는 우울집단과 사회불안집단의 부정적 자극에 대한 정보처리 편향인 기분일치기억(Mood Congruent Memory)을 암묵기억-외현기억 차원과 유사한 자동처리-통제처리 차원에서 비교하였다. 이를 위해 대학생 중에서 우울집단, 사회불안집단, 그리고 통제집단을 각각 20명씩 선정하였으며, 이들을 대상으로 Jacoby(1991)가 제안한 처리해리절차(Process Dissociation Procedure)에 따라 부정적 단어 및 중립적 단어에 대한 통제처리, 자동처리 추정치를 측정하였다. 실험 결과 우울집단에서는 부정적 단어에 대한 통제처리 편향이 통제집단에 비해 유의미하게 높게 나타났으나, 자동처리 차원에서는 그러한 편향이 나타나지 않았다. 반면에 사회불안집단에서는 부정적 단어에 대한 자동처리 추정치가 세 집단 중 가장 높게 나타났으나 통제집단에 비해 유의미하게 높지는 않았다. 또한 사회불안집단에서는 부정적 단어에 대한 통제처리 추정치 자체는 통제집단과 유사한 수준이었으나 중립단어보다 부정적 단어를 보다 잘 기억하는 통제처리 편향 정도가 우울집단과 유사하게 나타났다. 이러한 실험결과를 부정적 정서자극에 대한 의식수준에서의 반추와 같은 우울증의 증상과 부정적 정서 자극에 대한 비의식적 수준에서의 회피 및 불편감과 같은 사회공포증의 증상들과 관련하여 논의하였다.

The purpose of the present study was to investigate information processing bias for negative stimuli associated with depression and social anxiety. Each 20 college students were screened for social anxiety and depression and control group. Students with BDI score in the higher 15%ile but SADS score in the lower 50%ile were assigned to the Depression Group and students with BDI score in the higher 15%ile but BDI score in the lower 50%ile were assigned to the Social Anxiety Group. Students with both BDI score and SADS score in the lower 50%ile constituted the Control Group. Process-dissociation procedure was used to measure the controlled and automatic processing as Jacoby(1991) had proposed. Results showed that the Depression Group showed significantly larger bias for negative words than the Control group in the controlled processing, but not in the automatic processing. In contrast, the group differences in the automatic processing bias did not reach statistical significance although the Social Anxiety Group showed the largest automatic processing bias for negative words among the three groups. The Social Anxiety Group also showed nearly the same degree of controlled processing bias for negative words. The findings were discussed in terms of its implications for symptoms of depression and social anxiety. Finally, limitations of the present study and future directions for further study were discussed.

251 -이 논문은 정보이용교육을 위해 정보처리학습모형을 사용할 것을 추천하고 있다. 정보처리학습모형은 심리적 도구로서 적절히 사용하면 학생들의 자기주도적, 자율적 학습, 창의성 함양, 학력제고를 도모할 수 있고 학생들의 정보이용능력을 미국학교도서관 협회와 교육공학회에서 제정한 정보이용능력기준에 미치도록 훈련하는 것이 쉽다고 주장한다. 이러한 주장은 정보처리학습모형을 사용할 때 사용하는 정보기술내역과 정보이용능력기준을 대비시킴으로서 규명하고 있다.

본 연구는 소비자의 사전지식, 광고맥락, 처리목적에 따라 소비자들이 광고내용을 범주처리 하는지 속성처리 하는지를 살펴보았다. 실험결과, 사전지식이 많은 소비자들은 광고와 제품간의 맥락이 일치할 때 범주처리를 그리고 불일치할 때 속성처리를 하는 것으로 나타났으며, 사전지식이 적은 소비자들은 맥락에 상관없이 속성처리를 하는 것으로 나타났다. 또한 소비자들의 광고처리목적이 광고평가일 경우 맥락이 일치할 때 범주처리를 그리고 불일치할 때 속성처리를 하는 것으로 나타났으며, 처리목적이 제품평가일 경우 맥락에 관계없이 속성처리를 하는 것으로 나타났다.

This study examined the effects of prior knowledge, context of advertisement and ad processing goals on ad information processing. For this study, it was necessary to observe the contrary hypothesis between two information processing theories: category process and piecemeal process. The results showed that the consumers with high level of prior knowledge used a category-based process when the context between ad and product was congruent and a piecemeal process when the context was not congruent. The consumers with low level of prior knowledge used a piecemeal process regardless of the context. In addition, for the ad processing goal, consumers used a category process when the ad context was congruent and a piecemeal process when it was not congruent. Also, in the case of product processing goal, they used a piecemeal process regardless of the context.

본 연구는 폭식 경향 집단의 인지적 도식을 형성하는 정보처리 과정에 대해 알아보고자 하였다. 이를 위해 서울과 경기 지역의 20대 여성 320명을 대상으로 한국판 섭식 태도 척도-26 (The Korean Version of Eating Attitude Test-26; KEAT-26), 폭식증 검사 개정판 (Bulimia Test Revised : Bulit - R), 폭식 척도(Binge Eating Scale, BES) 설문지를 진행하였다. 설문의 결과를 토대로 ‘폭식 경향 집단’ 14명과 ‘통제 집단’14명을 구성하여 실험을 진행하였다. 실험 과제는 Fenton과 Ecker(2015)의 연구에서 사용된 작업 기억 과제(Working Memory Updating Task)로, 실험을 통해 폭식 경향 집단과 통제 집단의 신체 단어, 음식 단어, 중립 단어의 단어별 정답 수, 처음 학습 시간, 부호화 시간, 회상 시간의 평균을 비교하여 집단 간 차이를 검증하였다. 본 연구의 결과로는 첫째, 폭식 경향 집단과 통제 집단의 전반적인 작업 기억 과제 수행 능력에서는 유의미한 차이가 나지 않았다. 둘째, 폭식 경향 집단과 통제 집단의 각 단어에 대한 첫 단어 학습 시간과 부호화 시간에서, 음식 단어에 대해서만 유의미한 차이가 있었다. 즉, 폭식 경향 집단이 다른 단어보다 음식 단어에 대해 더 빠른 학습과 부호화를 하였으며, 이는 폭식 경향 집단이 음식 관련 자극에 대해 특정한 주의 편향이 존재한다는 인지적 도식-정보처리 이론을 지지하는 결과라고 볼 수 있다. 셋째, 폭식 경향 집단과 통제 집단의 신체 단어에 대한 첫 단어 학습 시간에서, 통계적으로는 유의미하지 않으나 집단 간 차이 경향성을 보였다. 반면, 부호화와 회상 시간에서는 유의미한 차이가 없었다. 즉, 폭식 경향 집단이 신체단어를 받아들이는 첫 순간에는 빠르게 반응하나, 이후 반복되는 신체 단어에 대해서는 회피 반응을 나타낸다는 것으로 해석할 수 있겠다. 본 연구는 폭식 행동에 영향을 미치는 인지적 도식과 도식을 형성하는 첫 단계인 정보처리 과정에 초점을 맞추어 신체, 음식, 중립 단어를 각각 구분한 새로운 작업기억 과제를 통해 실험-통제 집단 간 차이를 확인하였다는데 의의가 있다. 추후 섭식 장애의 도식부터 작업기억에 이르는 인지적 특성을 이해하고 치료에 보다 효과적인 방법을 개발하는데 도움이 될 것으로 기대한다.

This study was to investigate the information processing process that forms the cognitive schema of the binge eating tendency group. 320 women in their 20s in Seoul and Gyeonggi-do responded to The Korean Version of Eating Attitude Test-26 (KEAT-26), Bulimia Test Revised (Bulit - R), Binge Eating Scale (BES). 14 binge eating tendency group and 14 control group were selected. The experimental task was a working memory updating task using the body words, food words, and neutral words. Each set of words took about 15 minutes, and the experiment with three sets of words took about 60 minutes in total. The differences between the binge eating tendency group and the control groups were examined by comparing the mean scores of the body, the food, the neutral word counts, the first learning time, the coding time, and the recall time. In the results, firstly, there was no significant group difference in the overall working memory task. Secondly, there were significant differences in the first word learning time and encoding time between groups only for food words. The binge eating tendency group performed faster learning and encoding of food words than other words. This result is supporting the cognitive schema-information processing theory that the binge eating tendency group has a specific attention bias toward food-related stimuli. Thirdly, it showed a somehow statistically significant tendency in the first word learning time of the body words in group comparison, but it didn't show any significant group difference in encoding and recall time. This result can be interpreted that while the reaction time for the first body-related word was fast, the response for the following repeated body-related words showed an avoidant tendency. This study is valuable in focusing on the cognitive schema that affects binge eating behavior and the information processing process, which is the first step in forming a schema. In particular, this study examines the differences between the binge eating tendency group and control groups through a new working memory task that dealt with independently a body, a food, and neutral words. In the future, it is expected that this study would help to understand the cognitive characteristics of eating disorders ranging from the schema to the working memory and to develop more effective therapy methods.

얼굴표정에 함의된 정서 특성에 대한 연구들은 대개 무표정 얼굴을 중립 정서자극으로 사용한다. 그러나 일상생활에서 흔히 무표정은 타인에 의해 부정적 정서의 표현으로 해석되는 경향이 있다. 본 연구에서는 유쾌 혹은 불쾌한 얼굴에 대한 무표정 얼굴의 상대적 현출성을 비교하기 위해 유쾌 또는 불쾌 얼굴표정 방해자극들 사이에 출현한 무표정 표적자극에 대한 시각탐색을 요구하였다. 탐색 과제의 반응시간과 정확도 자료에 대한 분석을 시도한 결과 유쾌보다는 불쾌 방해자극 사이에 표적 자극이 출현한 경우 반응시간이 지연되었으며 정확성 또한 감소한 것이 관찰되었다. 이러한 상대적 부정확성은 무표정과 불쾌 방해자극을 서로 구분하는 민감도(d')의 저하에 의한 것으로 나타났다. 또한 ex-Gaussian 모형에 근거하여 개별 참가자들의 반응시간 분포를 유쾌 혹은 불쾌 방해자극 조건 간 상호 비교하였다. 표적있음 시행의 불쾌조건에서의 반응시간 지연은 의사결정 및 반응선택이 초래하는 편포성 증가에 기인한 것으로 나타났으며, 특히 이러한 반응시간의 지연은 표적없음 시행에서 분포의 전반적 지연과 함께 더욱 두드러졌다. 본 연구의 결과는 유쾌 및 불쾌 표정의 맥락 내에서 무표정한 얼굴이 출현할 경우, 무표정 얼굴은 지각된 정서가(emotional valence) 차원에서 유쾌 표정보다는 불쾌 표정과 상대적으로 구분되기 어려움을 시사한다.

Many studies characterizing perceived emotion on one’s face have used emotionless faces as neutral face stimuli. In our daily circumstances, however, an emotionless face tends to represent a negative expression of emotion rather than purely neutral. The present study aimed to compare the saliency of an emotionless face against either smiling or frowning faces, and asked participants to search for a target of an emotionless face among the distractors of either smiling or frowning faces. The analyses of search found delayed RTs as well as inaccurate search performance if the target was displayed among the frowning distractors rather than among smiling faces. The relative inaccuracy of target search was shown to derive from the decrease of sensitivity (d’) for discriminating the emotionless target from frowning distractor faces. We also compared the search RT distributions according to the ex-Gaussian model across the smiling and frowning distractor conditions. The ex-Gaussian analyses showed that the delayed RTs in the frowning condition owes to an increase of skewness in the distribution as a result of decision and response-selection processes. The skewness became more evident in the target-absent trials with an overall delay in their RTs. The results of the present study indicate that the emotionless faces is more difficult to distinguish from frowning faces than smiling faces if it is displayed among either of the two faces.
