This study aims to explore older adults' experiences on cognitive and physical barriers and emotional changes of interactions from their health information seeking. Total of 10 older adults aged 65 or more were individually interviewed. The results show that the older adults may experience more difficulty from the perspectives on cognitive and physical barriers. The cognitive barriers are to: 1) know information resource and information search skills, 2) to choose relevant information, and 3) to know information search tools. The physical barriers for them to consider are eyes, hands, legs, and the whole body when accessing health information. In terms of emotion, the older adults express curiosity and negative emotion and at the beginning of the search and then they have more emotional expressions in the middle, and then they express positive emotion at the end of the search. The results suggest that information professionals should consider library as a connection to help them reduce these barriers and stabilize emotional changes.

Everyday hearing handicap caused by presbycusis ultimately reduces quality of life in older adults. The aim of this study was to explore effects of cognitive impairment on self-reported hearing handicap in older adults with early-stage presbycusis. We compared K-HHIE scores between 40 elderly subjects with mild cognitive impairment (MCI) and age- and hearing-threshold matched 40 cognitively normal elderly (CNE) subjects. The results are as follows: 1) The MCI group scored significantly higher than the CNE group on the social/situational and emotional sections, and in total. 2) The MCI group scored significantly higher than the CNE group on all four subscales, and the most significant group difference was on the first subscale relating to interpersonal relationships and social handicaps. 3) Both groups scored highest on the item 8 (problems hearing whispering sounds) and item 15 (problems hearing TV or radio sounds). Besides those two items, the MCI group also scored high on the item 21 (problems hearing in a restaurant), item 6 (problems hearing when attending a party), item 3 (avoiding groups of people), and item 20 (personal or social restrictions). Our findings suggest that, among older adults with early-stage presbycusis, older adults with cognitive impairment tend to report greater everyday hearing handicap than their peers with normal cognitive function. Especially, they show significant problems hearing in background noise or multi-talker situations, which cause social restrictions and social/emotional loneliness.

이 연구의 목적은 문헌고찰을 통해 초보 프로그래머가 겪는 어려움의 원인을 이해하고 보다 효과적인 교육 방향과 전략을 수립하는데 기여하는 데 있다. 그래서 인지 과학적 관점에서 프로그래밍에 필요한 지식의 유형에 따라 초보 프로그래머가 겪는 어려움에 대해 고찰하였다. 이 연구의 결론은 1)초보 프로그래머들은 구문 지식, 개념적 지식, 전략적 지식의 부재로 어려움을 겪고, 특히 개념적 지식의 부재가 가장 많은 원인으로 확인되었고, 2)교육용 프로그래밍 언어를 이용한 입문자 과정에서는 학습자의 개념적 지식 형성에 중점을 두고 지도해야 하고, 3)초보 프로그래머가 전략적 지식을 배양하기 위해서는 컴퓨터의 특성을 올바로 인지할 수 있게 도와주어야 하고, 4)프로그래밍에 필요한 개념적 지식의 실체를 구체적으로 밝혀야 할 이유를 확인하였다.

This is a qualitative research that was carried out to analyze the childhood cancer survivors' perceived difficulties using the result of focus group interviews. This study conducted interviews with 22 childhood cancer survivors under follow-up management after cancer treatment at general hospitals in Korea. 22 persons were divided into 3 groups, and interviews were carried out with each group for 80-100 minutes. As a result of the research, four topic collections consisting of 'Physical limitation', 'Influence of lasting childhood cancer', 'Difficulty in forming relationships' and 'Lack of reliable information' and seven subjects, which consist of 'Lack of energy', 'Potential late-effects', 'Fears about cancer recurrence', 'Negative social awareness', 'Difficulty in interacting with', 'Difficulty in interacting with peers', and 'Difficulty in interacting with families' were derived. Based on the findings of this research, it is hoped that provides a basis for developing appropriate and effective services and programs for childhood cancer survivors.

The purpose of this study is to analyze the errors and difficulties which pre-service secondary teachers shows during the task modification in consideration of the cognitive demand and to provide significant implications to the pre-service teacher education program related to the modification of the mathematical tasks. In the pursuit of this purpose, tasks were selected from perpendicular bisector units and 24 pre-service teachers were asked to modify the tasks to higher and lower level tasks. After the modification activities, opportunities for reflection and modification were provided. The findings from analysis are as follows. Pre-service teachers had a difficulty to distinguish between PNC tasks and PWC tasks. Also, We identified the interference phenomena that pre-service teachers depended on the apparent elements of the task. Pre-service teachers showed a tendency to overlook the learning objectives and learning hierarchy during the task modification, and to focus on some types of task modification. However, pre-service teachers were able to have meaningful learning opportunities and extend the category of tools to technology including Geogebra through self-reflection and correction activities on task modification. The above results were summed up and we presented the implications to the task modification program in the pre-service secondary teacher education.

본 연구는 교사가 교육용 웹사이트에서 교육 자료를 검색할 때의 인지과정을 탐색해 보고 교사가 어떠한 부분에서 인지적 어려움을 겪는지 분석하고자 하였다. 이를 위해 세 명의 교사에게 교육 자료를 검색하는 세 가지 과제를 준 후, 과제 수행 시의 인지과정을 PBG 그래프(Problem Behavior Graph)를 활용하여 분석하였다. 분석결과를 바탕으로 교육용 웹사이트의 사용성 향상을 위한 개선 방안을 제안하였다.

This study aims to examine the effects of employment on the physical health, psychological function, and life satisfaction of the elderly. Participants were 4,165 persons (men 1,739, women 2,426) aged 65 over. Physical health was composed of ADLs(Activities of daily living), pains, and disorders. Psychological function was measured by cognitive functions (subtraction, instruction execution, memory test, and item use) and emotional difficulty. Life satisfaction, work satisfaction, and work level were also measured. Major findings in this study are as follows: First, gender, marriage, and education level had significant effects on the participants' life satisfaction, but religion and financial incomes did not. Second, employment had significant effects on their physical health, psychological function, and life satisfaction. Third, pain, cognitive functions, emotional difficulty, and work satisfaction had significant effects on the life satisfaction of the working elderly. But, work level and incomes had not significant effects on the elderly's life satisfaction. In addition, an interaction between cognitive functions and emotional difficulty on life satisfaction was found.

Among many design processes such as learning, storing, retrieving and applying, the process that learns design knowledge is very important for producing creative results that solve design purposes in design computations. The computer should have the ability similar to human in learning design knowledge. It should recognize not only physical properties but also high level design knowledge constructed from the first level physical properties. The high level design knowledge are recognised in terms of isometric translation relationships. This paper explains properties of isometric translation and methods how the computer can recognize high level shape design knowledge using shape pattern representation.

과학영재의 인지적 영역을 발달시키기 위한 연구는 활발하게 진행되었지만, 과학영재가 겪고 있는 사회-정서적 어려움과 어려움을 해결하기 위한 지원 체계에 대한 연구는 부족하다. 과학영재는 낮은 자아존중감으로 인하여 정서적 민감성, 과흥분성, 완벽주의, 실존적 우울감 등 다양한 정서적 어려움을 겪고 있다. 선행연구에서는 과학영재의 정서적 어려움을 지원하기 위해서는 지속적이고 개별화된 상담이 필요하다고 말하였다. 하지만, 시공간적 한계로 인하여 지속적이고 개별화된 상담을 진행하는 데 많은 어려움이 존재한다. 따라서 본 연구에서는 과학영재에게 지속적이고 개별화된 상담을 제공하기 위하여 온라인 상담 시스템을 설계하였다. 온라인 상담 시스템은 과학영재가 내인적 요인에 따른 상담을 신청하면, 상담 전문가가 Peterson과 Moon(2008)의 상담 모형을 기반으로 상담을 지원하도록 설계하였다. 향후 연구에서는 이러한 상담 시스템을 구축 및 실행하여 시스템에 대한 과학영재의 만족도와 자아효능감의 변화를 관찰하고자 한다.

The argument-structure distributions of predicates in the speech of two roca-type aphasic patients and one Conduction-type patient are compared with both matched controls and each other on the basis of narrative production data. Whereas English-speaking agrammatics have been reported to have difficulties producing noncopular unaccusative predicates (Kegl 1995) Korean-speaking agrammatics are found not to have particular difficulties with unaccusative predicates. On the assumption that agrammatics lack specific syntactic knowledge for the processing of displaced arguments from their lexically specified positions. it is proposed that unaccusatives in Korean do not involve the displacement of arguments for Case-theoretic reasons or involve a vacuous movement. if any.
