Korean archival community had continuously dealt with attempts at weakening the core of records and archives principles in the name of deregulation. In 2015, Korean government announced revisions of the Archives Law in order to boost uses of commercial records facilities by public institutions. As key concepts were unclear and understandings among stake-holders varied, a considerable degree of chaos and anxiety aroused. The amendment itself was held at National Assembly. The unresolved disputes rested, however, waiting for another attempt of similar nature. As the recognition propelled this paper, it aimed at reviewing major contending arguments and proposing future actions.

Psychological essentialism states that people believe some categories to have hidden and defining essential features which cause other features of the category (Gelman, 2003; Hirschfeld, 1996; Medin & Ortony, 1989). Essentialist belief on categories questions the Roschian argument (Rosch, 1973, 1978) that categories merely consist of clusters of correlated features. Unlike family resemblance categories, essentialized categories are likely to have clear between-category boundaries and high within-category coherence (Gelman, 2003; Prentice & Miller, 2007). Two experiments were conducted to test the effects of essentialist belief on category representation (i.e., between-category boundary, within-category coherence). Participants learned family resemblance and essentialized categories in their assigned conditions and then performed categorization task (Expt. 1) and frequency estimation task of category exemplars (Expt. 2). The results showed, in essentialized categories, both boundary intensification and greater category coherence. Theses results are likely to have arisen due to increased cue and category validity in essentialized categories and suggest that essentialist belief influences macroscopic representation of category structure.

The purpose of this convergence study was to examine the effects of smart learning on learner's participation, academic self-efficacy and task value in nursing education. The study was designed using a nonequivalent control group no-synchronized design. The subjects of this study consisted of 86 experimental group and 95 control group who were nursing students. Data were collected from March 2 to June 8. 2018. The data were analyzed using the spss 18.0 program to perform independent t-test. There were not statistically significant differences in learner's participation(t=1.065, p=.288) but were statistically significant differences in academic self-efficacy(t=2.668, p=.008) and task value(t=2.070, p=.040). Therefore, the smart learning was effective in increasing academic self-efficacy and task value for nursing students. The smart learning is expected to be useful as effective teaching and learning strategies in nursing education.

2차원 하천흐름. 유사이동, 오염확산 해석을 위해서는 유한요소법(FEM) 등을 활용한 수치해석 모델이 사용되며, 이 때 모델링을 위해서 모의영역은 2차원의 요소망으로 구성하게 된다. 기존 국내 연구에서는 이러한 2차원 요소망 생성 및 수치해석을 위해 SMS 및 CCHE2D와 같은 외국의 상용 프로그램을 이용하였으나, "수자원의 지속적 확보기술개발 사업"의 일환으로 수행중인 "RAMS(River Analysis and Modeling System) 개발" 과제를 통해 순수 국산 2차원 수리해석 소프트웨어가 개발 중에 있다. 본 연구에서는 RAMS를 비롯한 기타 수리해석 모델에서 사용 가능한 2차원 범용 요소망 생성 프로그램을 개발하고자 다양한 요소망 생성 기법 및 국외 상용 2차원 수리해석 모델 프로그램에서의 메쉬 생성방법 등을 분석하여 프로토타입 메쉬 생성기를 개발하였다. 현재 개발 중인 요소망 생성 프로그램은 요소망 생성을 위한 기본 기능 외에도 생성된 요소망 데이터를 RAMS에 포함되어 있는 다양한 2차원 유한요소 모형의 입력자료 형태로 변환함으로써 수리해석에 적용가능하다. 이러한 범용 2차원 요소망 생성 프로그램의 개발은 안정적인 수치해석의 기반을 제공하고 다양한 하천흐름, 유사, 수질 해석 모델과 연계함으로써 하천의 수리학적인 거동을 보다 정확히 모의할 수 있을 것으로 기대된다.

본 연구에서는 사용성 테스트와 사용자 설문조사 단계를 거쳐 고연령계층 사용자를 고려한 통합 리모컨 버튼 레이아웃을 도출하여 고연령층의 사용편의성이 반영된 리모컨의 사용성을 향상시키고자 하였다. 이를 위하여 일차적으로 신체, 인지심리적인 고연령층의 인간요소(human factor)들을 추출한 다음, 고연령계층 중 연령대별 남녀 사용자를 모집하여 현재 사용되는 기존의 리모컨으로 사용자에게 과제를 부과하여 사용성 테스트와 설문조사를 실시하였다. 사용성 테스트 결과를 중심으로, 통합 리모컨 버튼 레이아웃 디자인 시 반영되어야 할 필수 기능 버튼의 도출과, 버튼 배열의 최적화된 모델을 제시 할 수 있었다. 또한 이러한 과정을 통해 UI 디자인 시 지켜져야 할 세가지 요소인, 연관있는 기능의 동일요소 부여로 동작의 상호 의사소통을 고려해야한다는 것(유사성)과 유사기능간 근접배치로 사용자가 동작할 수 있는 버튼을 쉽게 이해하도록 해 주어야 한다는 것(근접성), 그리고 예상되는 연속 동작의 기능을 동선을 고려해서 배치해야 한다는 것(연속성)을 확인하였다. 마지막으로, 한 가지 기준에 의한 일률적인 버튼 배열보다 사용자의 요구사항과 인지적 한계를 반영한 그룹핑을 고려한 버튼 배열이 사용성을 높이는 중요한 요인이라는 것을 알 수 있었다.

디지털 카메라의 대중화와 고용량 저장매체의 보편화로 인해 대중들은 손쉽게 디지털 사진 촬영이 가능하게 되었다. 디지털 사진은 필름 사진과 달리 촬영을 하는데 있어 비용이 들지 않을 뿐만 아니라 플래쉬 메모리의 증가로 인해 다수의 사진들을 촬영할 수 있게 되었으나 그만큼 많은 사진들을 관리하고 분류하는 것은 쉽지 않은 일이 되었다. 따라서 디지털 사진을 자동으로 분류하고 관리하는 기능은 중요한 과제가 되었지만, 현재까지 나온 방법들은 사진 내의 객체가 확대, 축소 및 이동하거나 배경이 바뀌는 영상에 있어서 정확한 유사도를 측정하여 분류하는데 어려움이 있었다. 본 논문에서는 이와 같은 어려움을 보완한 디지털 사진의 클러스터링 알고리즘을 제안한다. 입력영상을 그리드 형태로 나누어 각 블록별로 측정한 유사도 값을 바탕으로 클러스터링하며, 이때 디지털 사진 내에 포함되어 있는 촬영정보인 EXIF를 이용하여 입력 영상에 따라 적응적(adaptive)으로 그리드를 나누어 비교한다. 또한, 영상에 따라 각기 다른 색상의 분포 정도를 고려해 색상 가중치를 고려하여 사진을 비교함으로써, 영상의 고수준(high-level) 분석에서처럼 객체와 배경을 추출하여 따로 분리하지 않고도 객체의 배경이 다른 사진들을 저수준(low-level) 에서 분석이 가능토록 하였다. 제안한 방법으로 실험한 결과 객체의 크기 및 이동이나 배경에 큰 영향을 받지 않으면서 입력영상들을 클러스터링 할 수 있었다.

This study was undertaken to observe the effects of partial replacement of acorn starch with dent, cross-linked, or acid modified corn starches, and of refrigeration on sensory characteristics of acorn mooks(starch gels). Triangle test was used to determine if there were noticeable differences among the monks. In order to find the source of differences, various sensory properties of the monks were evaluated with quantitative descriptive analysis on unstructured scale. The results indicated that added corn starches affected significantly most of the sensory characteristics evaluated. Control acorn monks had greater intensities in color, clarity, bend property, firmness and cohesiveness. Monks containing cross-liked corn starch were more similar to control than the other mixed starch monks, fresh or refrigerated.

Lately innovation is perceived as a systemic, horizontal phenomenon and requires a new governance for innovation. Subsequently, broader societal questions enter the domain of innovation policy and coordination and integration between innovation policy and various other policy domains, such as economic, educational, social, regional and environmental policies become crucial. Definitions of policy integration include terms such as coherence, cooperation, coordination and put great emphasis on joint working to promote synergies among policies and reduce duplication and the use of the same goals to formulate policy. As innovation capabilities of the private sector have improved and it has become unclear who to catch up with, the Korean government, a leading player in the process of "catch-up," is likely to have more difficulties in maintaining the old way of planning and executing policies. The Korean government is now under the pressure of planning technologies and policies that do not allow any easy imitation or copy of other advanced countries longer, which in turn reveals various limits of the existing policy framework. Policy integration involves a continual process demanding changes in political, organizational and procedural activities. To ensure long term and cross sectoral innovation policy, overall change and improvement in policy and its implementation needed in terms of political commitments, governance systems, policy instruments and monitoring, and evaluation systems.
