'바른 우리글 쓰기' 학습시스템은 우리말 작문 학습에 필요한 지식을 익히도록 하고자 만들었다. 이 논문의 궁극적인 목표는 한국어 철자/문법 검사기와 국어 학습시스템을 연계하여 학습자가 적극적으로 학습에 참여하도록 동기를 부여하는 능동적인 언어 학습 시스템의 구현이다. 흔히 웹에 기반한 학습시스템에서 학습자는 일방적으로 정보를 제공받거나 독립적인 위치에서 자율적인 학습을 해나가야 하므로 끊임없는 흥미와 관심이 없이는 효율적인 성과를 거두기 어렵다. 이와 같은 약점을 보완하려는 맥락에서 이 학습시스템은 학습자가 스스로 학습한 후 그 결과를 평가 문제나 한국어 철자/문법 검사기를 통해 즉각적으로 확인해 보고 부족한 내용을 공부할 수 있도록 한다.

As evolution of multimedia technology brings changes to industries concerned with design, new education program is needed to cultivate designers with abilities which are adapted to changed circumstance. This paper is purposed to show guideline to set up a fundamental course for multimedia design in which students know what are new presentation modes and learn how to use them, Multimedia design call for abilities of organizing information, representing, and implementing interactivity. Among them, fundamental course considers representing information as central subject. And it also contains lessons which are relative to proceeding courses. It should have students to experience creative composition and various expressions, and study cognitive or aesthetic effects of them. All activities are based on the understanding about presentation factors and principles. Basic course's lessons are composed by two main subjects, which are essential expression and matters relative to organization and interactivity. Described in detail, lessons are divided into three phases. First phase is combining presentation factors for affective effects, second is delivering message of various knowledges and third is forming simple interaction.

This study aims to examine how visitors in science centers interact with gesture-based exhibits from embodied cognition perspectives. Four gesture-based exhibits in two science centers were selected for this study. In addition, we interviewed a total of 14 visitor groups to examine how they perceived the property of gesture-based exhibit. We also interviewed four experts to further examine the benefits and limitations of the current gesture-based exhibits in science centers. The research results indicate that the total amount of interaction time between visitors and gesture-based exhibits was not high overall, implying that there was little of visitors' immersive engagement. Both experts and visitors expressed that the current gesture-based exhibits tend to highlight the novelty effect but little obvious impacts linking gestures and learning. Drawing from the key findings, this study suggests the following design considerations for gesture-based exhibits. First, to increate visitor's initial engagement, the purpose and usability of gesture-based exhibits should be considered from the initial phase of design. Second, to promote meaningful interaction, it is important to sustain visitors' initial engagement. For that, gesture-based exhibits should be transformed to promote intellectual curiosity beyond simple interaction. Third, from embodied cognition perspectives, exhibits design should reflect how the mappings between specific gestures and metaphors affect learning processes. Lastly, this study suggests that future gesture-based exhibits should be designed toward promoting interaction among visitors and adaptive inquiry.

The purpose of this study is to identify the image of the feel of the local festival visitors participated in local festivals, the local festival image Impact on vistor's satisfaction, revisit and intention of recommendation. In addition, empirically how the visitor's satisfaction impact on their revisit and intention of recommendation. Analysis showed that local festival image factor is derived by three factors, such as cognitive image factor, emotional image factor, facility image factor. All three factors ware seen as the important factors affecting the visitor's facilities satisfaction, but only emotional image of the three images was a factor affecting the visitor's operating satisfaction. Above all should be considered cognitive image Among the three images(cognitive images, emotional images, facilities Images) To enhance the visitor's revisit and intention of recommendation. In other words, it is important that the position of local festival be considered. Should try to raise the quality of cognitive images to improve the visitor's satisfaction, revisit and intention of recommendation at the same time.

The purpose of the study is to survey and identify the degree of cognition of women in their 20s in Korea for cervical cancer screening which has been expanded to those aged 20 as the age for the screening since January 2016, and to reveal its correlation with intention of screening. The responses to the questionnaire of the survey conducted on total 353 females in C region were collected for the data from Nov 1, 2017 to Nov 10, 2017. The frequency analysis, chi-square test and logistic regression analysis were conducted by utilizing 353 copies of the questionnaire. According to the result, only 129(36.5%) answered that they recognized the current system of cervical cancer screening. Besides, the intention of screening in case of recognizing the cervical cancer screening project was 1.63 times higher than when it is not the case. Therefore, it is required to raise the participation of screening of women in their 20s by intensifying education and promotion on cervical cancer screening for women who are not yet in their 20s in linkage with health care projects at schools.

항공기 엔진 체계의 신뢰성과 안전성을 분석하는 것은 RAM 분석이라고 한다. RAM은 제작자가 개발한 시스템의 지속가능성 혹은 그 체계의 수명주기비용(Lice Cycle Cost)에 중대한 영향을 줄 수 있는 시스템 설계특성을 의미한다. 또한 RAM은 시스템이 개발될 당시에 의도된 임무를 수행할 수 있는 능력 혹은 임수수행을 성공할 수 있도록 담보하는 중요한 역할을 한다. RAM은 1970년대 이후 미국 군수분야에서는 군수지원성분석(LSA, Logistic Support Analysis) 과 밀접히 연계되어 활용되어 왔으며, RAM과 LSA를 통합하여 종합군수지원체계(ILS, Integrated Logistics Support)라고 부른다. 본 연구에서는 항공기 엔진에 대한 신뢰성 분석에 Weibull 분포를 활용하였다. Weibull 분포는 2개의 변수 적용에서 다음과 같이 정의된다. 변수가 그 계의 어떤 값을 나타내느냐에 따라 분포도 곡선의 특성 의미는 변수에 의존된다. 예를 들어 시험성적, 사회적 특성을 표현하는 인지도, 산업 제품의 고장이나 결함을 나타내는 고장관련 모수(변수) 등에 따라 그 특징을 나타내게 된다. 항공기 엔진의 신뢰성 분석을 통해 항공기 엔진의 수명 판단이 가능해졌으며 임무 불가능 수준의 In-Flight Shut-Down 비율이 현격히 감소됨을 확인할 수 있었다.

Objective: Research on children's death concepts requires an approach considering social and cultural context. A qualitative method is necessary to explore children's cognitive process of understanding death. Thus, this study, to overcome the limitations of the quantitative approach based on the deductive logic led by adult researchers, adopted a qualitative research method. Methods: The data collection, referring to the theories of Corr and Balk (2010) and Smilansky (1987), used Death Concept Questionnaire. Each structured question was followed by open follow-up questions to explore how children understood each concept of death. Results: The results showed that participant children were still lacking in the acquisition of death sub-concepts. The qualitative result from open interview showed how children can and can not acquire the concepts of death. Conclusion/Implications: The study could be used in future development of death education programs for children. Based on the results of this research, it is necessary to develop programs for children's death education, which would help them coping with death related anxiety and loss experiences.

This study examined whether structural (coresidence, proximity) and associational (frequency of face-to-face contact, frequency of contact via phone, email or letter) solidarity between adult children and older parents may influence older parents' cognitive functioning. Adult children may help delay older parents' cognitive decline by promoting healthier lifestyle, engaging parents in complex everyday problem solving, and providing emotional support. The data consisted of men and women 65+ at Wave 1 who had at least one child 20+ and participated in at least two waves of the Korean Longitudinal Study of Ageing (KLoSA, N=3,961). Cognitive functioning was measured with the Korean version of the Mini Mental State Examination. Fixed effects models were estimated using the xtreg procedure in STATA. Findings suggest that increases in proximity with at least one adult child may lead to enhanced cognitive functioning among older parents. Neither transitioning to coresidence with at least one adult child nor increases in frequency of contact with at least one non-resident adult child was associated with changes in older parents' cognitive functioning. With older parents' increasing preference for living close by, but not necessarily living with adult children, greater proximity may provide more opportunities for reciprocal support exchanges between the two generations, leading to better cognitive functioning of older parents.
