  • Due to the lack of information, medical tourists are regarded to be at high risk. Prior medical tourism research has found that various types of perceived risks have a significant impact on medical tourists' purchase behavior. Even though medical tourism is predicted to increase, there is a lack of behavioral research to explain how perceived risks affect medical tourists' purchase behavior. In the context of Korean medical tourism, this study attempts to evaluate the effects of multi-level (macro, organizational, and personal) factors on medical tourists' perceived risks and purchase intentions. A conceptual model and hypotheses were built and empirically validated to investigate links between multi-level characteristics, perceived risks, and purchasing intentions. The data for this study was collected from Chinese tourists using a questionnaire. The impact of cognitive country image, affective country image, and medical service quality on fundamental risk is confirmed by statistical testing. Surprisingly, expectancy discrepancy risk is influenced only by cognitive country image and information search capabilities. Both fundamental and expectation discrepancy risks lower medical tourists' purchase intentions. The findings of this study show that a multi-level strategy is required to investigate the links between perceived risks and medical tourism purchasing intentions based on macro, organizational, and personal factors.

  • Electronic brainstorming (EBS) to improve the process and outcomes of group decision making is an artifact of Information Systems legacy. Despite three decades of research with EBS in an effort to become a key resource of organizational performance, its performance when compared to that of nominal is inconclusive because of the recent debate over its usefulness in terms of productivity. Subsequent researchers have directed our attention to the re-examination of cognitive stimulation, which is considered the major benefit in computer-based idea generation, to explain the performance singularity in computer-based groups. While both cognitive and motivational factors that moderate and mediate the group-interaction process remain unexplored, individual differences that are tightly linked to creative behavior have been largely ignored to account for the discrepancy in performance. Since simulations have been widely used in situations where an outcome does not meet the assumptions, the notion of a group simulator and detailed simulation mechanisms are introduced to examine the potential effects of individual differences on the performance of computer-based idea generation groups. In addition, two prior studies that empirically explored cognitive mechanisms with the group simulator are showcased along with six propositions to initiate future research.

  • Translocator protein (TSPO), also known as peripheral benzodiazepine receptor, is a transmembrane protein located on the outer mitochondria membrane (OMM) and mainly expressed in glial cells in the brain. Because of the close correlation of its expression level with neuropathology and therapeutic efficacies of several TSPO binding ligands under many neurological conditions, TSPO has been regarded as both biomarker and therapeutic target, and the biological functions of TSPO have been a major research focus. However, recent genetic studies with animal and cellular models revealed unexpected results contrary to the anticipated biological importance of TSPO and cast doubt on the action modes of the TSPO-binding drugs. In this review, we summarize recent controversial findings on the discrepancy between pharmacological and genetic studies of TSPO and suggest some future direction to understand this old and mysterious protein.

  • The aim of this study was to develop and implement a program based on Cognitive Behavior Therapy (CBT) for female college students experiencing body dissatisfaction. To systematize the program development process, we adopted the service design method. First, we conducted In-Depth Interviews (IDIs) to identify the difficulties faced by six female college students who experience body dissatisfaction, and to determine what kind of help they needed. Second, content analysis of the findings revealed that female college students were experiencing emotional-behavior problems which derived from the discrepancy between their ideal body image and the reality. Third, a prototype of a cognitive reconstruction program was developed to help transform their perceived 'body distortion' to a rational cognitive concept and thus reduce maladaptive consequences of 'body dissatisfaction'. The overall program consisted of three therapeutic components and seven steps. Fourth, to assess the effectiveness of the program, survey and IDIs were conducted. The results revealed that it is appropriate to use a cognitive model to solve problems caused by body dissatisfaction, and that understanding and reconstructing one's own cognitive processes can be effective in reducing body dissatisfaction. However, based on feedback from participants, a number of revisions were proposed, such as including sufficient induction regarding the behavioral change.

  • Purpose - This research aims to understand the different behaviors of consumers according to cognitive age. Specifically, this research is focused on pro-social behavior. Pro-social behavior is defined as behavior benefiting others, rather than behavior benefiting one's self. It often entails individual risk or cost, such as when giving resources to others, waiting in line, asking for or paying a fair price, or risking one's life in battle. Therefore, we sought to understand consumer psychology and cognitive age as a reflection of inner psychology. People frequently perceive themselves as younger or older than their chronological ages. This self-perceived or cognitive age is a subjective age perception independent of actual chronological age. The discrepancy degree between chronological and cognitive age represents how much individuals perceive themselves as younger than they are. This study examines the gap in donation intention based on cognitive age. In order to investigate cognitive age, composed of four sub-categories (feel-age, look-age, do-age, and interest-age), this study explores the differential donation intention based on cognitive age, which determines the relationship between the young age and old age. Research design, data, and methodology - Data research was conducted by gathering 216 survey samples, excluding those with unreliable answers. Data coding and cleaning were used and SPSS 19.0 software for the data analysis. The respondents were categorized into two types, younger cognitive ages and older cognitive ages. Additionally, we analyzed the moderating variables. In particular, we used cognitive age degree and congruency level (cognitive age low vs. cognitive age high) × (congruency close vs. congruency distant) between - subjects design. First, regression was done to verify the difference between chronological age and cognitive age. Second, a t-test was done to verify the difference of cognitive age level in donations. Third, ANOVA (analysis of variance) was done to verify the difference between cognitive age and congruency in donations. Last, ANOVA was done to verify the difference between cognitive age and moral judgments in donations. Result - The results show most respondents perceive themselves as younger than their chronological ages. In particular, older respondents feel they are younger than their actual age. Moreover, the result of the comparison between low degree and high degree groups of cognitive age, show high donations at the higher degree of cognitive age groups. In addition, the closer the distance to the beneficiaries, the higher the donation in high degree cognitive age groups. The higher moral judgment groups also show relatively high contributions in lower degree cognitive age groups. Conclusions - Donations belong to the category of pro-social behavior reflecting an individual's psychological state. Therefore, it is important in understanding cognitive age. This study implies that it is necessary to take into account both cognitive age and chronological age when segmenting donors. Moreover, this study confirmed that there are different factors affecting the motives behind donations. Thus, it may be utilized to create differential donation strategies.

  • 이 연구는 과학 교육 현장에서 인지적 정의적 평가를 중심으로 한 양적 자료와 질적 자료에서 나타나는 몇 가지 불일치 사례를 분석했다. 308명의 고등학교 2학년 학생을 대상으로 학업 성취도와 정의적 성취도를 양적 자료로 수집했고, 그 중 33명의 학생을 면담한 질적자료를 분석했다. 주로 검사 도구의 측면에서 불일치 사례의 원인과 유형을 고찰했다. 연구 결과 양적 자료인 인지적 성취와 정의적 성취 영역 각각에서 과목별, 구인별 차이가 크게 나타나는 학생들이 상당수 있었고, 특히 두 영역 간 성취도 경향이 일치하지 않는 학생들도 20% 이상 분석되었다. 선택한 진로와 진학을 위해 의도적으로 과학 학습을 조절한 사례, 학교 과학과 과학에 대한 인식 차이에 따라 다른 반응 등의 사례가 면담을 통해 발견되었다. 도구로 측정한 양적 자료와 학생들의 면담 내용인 질적 자료를 비교한 결과 스스로 반응한 양적 자료와 다르게 자신을 평가하는 학생들이 대부분이었다. 이는 다양한 특성을 지닌 학생들이 검사 도구와 상호작용하는 과정에서 비롯된다. 검사 도구와 관련된 불일치 유형은 '문항 개발자가 의도한 개념과 학생들이 이해하는 개념 간 차이'와 '표현된 반응과 속마음 간의 차이'로 나타났다. 검사 도구에서 사용한 용어가 학생들에게 모호하게 인식될 때 자의적이거나 일관성 없이 반응하는 경우가 전자에, 사회적 바람직성이나 자아 방어 기제에 의한 반응 왜곡은 후자에 해당한다. 이상 연구 결과를 바탕으로 자기보고식 검사 도구가 학생들의 실제 인식을 잘 반영하고 있는지 검토하고 정교화하려는 노력, 학습 경험을 획일적으로 고정시키는 평가 개선 등이 필요하다.

  • The present study examined if individual listeners' perceptual variations were associated with their cognitive characteristics indexed by the Autistic Spectrum Quotient (AQ). This study first investigated the perception of the lexical pitch accent contrast in the Kyungsang Korean currently undergoing a sound change, and then tested if listeners' perceptual variations were correlated with their AQ scores. Eighteen Kyungsang listeners in their 20s participated in the perception experiment where they identified two contrastive accent words for auditory stimuli systematically varying F0 scaling and timing properties; the participants then completed the AQ questionnaire. In the results, the acoustic parameters reporting reduced phonetic differences across accent contrasts for younger Kyungsang generation played a reliable role in perceiving the HH word from HL, suggesting the discrepancy between the perception and the production in the context of sound change. This study also observed that individuals' perceptual variations were negatively correlated with their AQ sub scores. The present findings suggested that the sound change might appear differently between production and perception with a different time course, and deviant percepts could be explained by individuals' cognitive measure.

  • 학생의 선개념은 일상적 상황의 경험을 바탕으로 형성된 반면, 과학적 개념은 이상화된 상황을 전제로 하여 형성된 것이므로, 개념변화에 필요한 학생의 인지갈등을 유발하려면 이러한 상황의 불일치를 고려할 펼요가 있다. 또한, 학생들은 자신의 생각과 불일치한 현상을 대면하였을 때, 적당한 보조가설을 도입하여 이를 설명하려 함으로 개념변화가 이루어지지 않을 수 있다. 오히려, 과학적 개념이 일상적 상황에서 잘 맞지 않는다고 학생들이 생각할 수 있으므로, 과학적 개념에 따른 보조 가설을 도입하여 일상적 상황의 현상을 설명할 필요가 있다. 본 연구에서는 이러한 점들을 고려한 개념변화 모형을 구안하고, 이에 따라서 보조 가설의 대비를 통한 인지갈등의 명료화, 이상적 상황의 관찰을 통한 과학적 개념의 개념적 지위 상승, 교량적 실험활동을 통한 학생의 선개념의 지위 하강을 통하여 개념변화가 이루어지게 하는 세 단계로 구성된 학습지도 모형인 '구조화된 대비활동'을 제안하였다.

  • Background: Determination of inter-method differences between clinically available volumetry methods are essential for the clinical application of brain volumetry in a wider context. Purpose: The purpose of this study was to examine the inter-method reliability and differences between the Siemens morphometry (SM) software and the NeuroQuant (NQ) software. Materials and Methods: MR images of 86 subjects with subjective or objective cognitive impairment were included in this retrospective study. For this study, 3D T1 volume images were obtained in all subjects using a 3T MR scanner (Skyra 3T, Siemens). Volumetric analysis of the 3D T1 volume images was performed using SM and NQ. To analyze the inter-method difference, correlation, and reliability, we used the paired t-test, Bland-Altman plot, Pearson's correlation coefficient, intraclass correlation coefficient (ICC), and effect size (ES) using the MedCalc and SPSS software. Results: SM and NQ showed excellent reliability for cortical gray matter, cerebral white matter, and cerebrospinal fluid; and good reliability for intracranial volume, whole brain volume, both thalami, and both hippocampi. In contrast, poor reliability was observed for both basal ganglia including the caudate nucleus, putamen, and pallidum. Paired comparison revealed that while the mean volume of the right hippocampus was not different between the two software, the mean difference in the left hippocampus volume between the two methods was 0.17 ml (P < 0.001). The other brain regions showed significant differences in terms of measured volumes between the two software. Conclusion: SM and NQ provided good-to-excellent reliability in evaluating most brain structures, except for the basal ganglia in patients with cognitive impairment. Researchers and clinicians should be aware of the potential differences in the measured volumes when using these two different software interchangeably.
