  • This study explored an alternative activity for the assessment of young children's literacy in Korea; namely, the evaluation of children's ability to construct meaning independent of decoding skill. The subjects were 78 children 4 to 5 years of age in Seoul. Instruments were the researcher's revised form of the Story Construction from a Picture Book, TRSR (Teachers' Ratings of Students' Reading) designed by van Kraayenoord & Paris (1996), and the revised form of the WLAT (Written Language Awareness Test, Kim, 1995). The assessment scores and oral responses of the children were analyzed by Pearson's r, MANOVA and one-way ANOVA, using repeated measures. The findings showed that (1) the story construction total scores were significantly correlated with WALT scores and the subcategory scores were intercorrelated with each other. (2) The story construction total scores differed by age, and (3) the 2 phase scores were higher than the 1 phase scores.

  • ^x This study is an attempt to present the possibility of environmental aesthetics and its characteristic form in Korea. This paper investigated the concept of art as a traditional theory of aesthetics through R.G. Collingwood and present- day analytic philosophers who had been influenced by the ordinary language philosophers in 1950s. Accordingly, the study focused on the institutional theory of art which was developed in reaction to M. Weitz′s views. The institutional theory of art concentrates attention on the nonexhibited characteristics that works of art have An virtue of being embedded in an institutional matrix which may be called "the artworld"and argues that these characteristics are essential and defining. Taking this position, the paper examined the relation between environment and art as aesthetic object because it would be one of the ways to find tole possibility and foundation of environmental aesthetics. Furthermore, these works will be the basis to create our proper landscape or ′our own environment′as a significant and a mental cultural landscape.

  • In this paper, a remote submersion warning system based on multi-mode optical fiber(MMF) sensors and a wireless sensor network(WSN) are proposed. To improve the reliability and stability of the sensors, the dual optical fiber sensors combined to the optical coupler are demonstrated. A slave zigbee as a wireless sensor module was used as a platform to monitor and record the signal from the MMF sensors and then transmits these information to a master zigbee wirelessly. The monitoring system running the $LabVIEW^{(R)}$ software was connected to the internet to support the short message service(SMS) through extensible markup language(XML) web service. No matter where the managers are, they can always receive the real-time remote-monitoring data for safety check.

  • A graphic user interface program for the design of vehicle suspension system is developed in this work. Graphic templates are designed by using a graphic language and a library and given to users for interactive data input. Several suspension types are graphically given, and the information of hard points can be directly provided on the graphic templates by users. The information is saved in a data structure which can be efficiently accessed, and transformed into another data format. The data transformation is for the interface to an analyzer by which suspension design characteristics can be calculated.

  • 본 논문에서는 사람의 이동정보인 위치데이터를 바탕으로 위치분석(Location Analysis)을 통해 나타난 개개인의 이동성 모델을 바탕으로 각 개인의 이동성 모델에서 나타난 군집들의 관계를 분석해 개인이 속한 집단의 이동성 모델을 만든다. 집단 이동성 모델은 개인의 모델에서 나타난 군집을 이용하는데, 각 군집을 만드는데 필요한 위치 정보들과 군집의 중심, 군집간의 거리의 값을 계산하여 새로운 통합 군집을 만든다. 새로 만드는 군집은 각 특징에 따라 Micro Cluster, Macro Cluster의 2가지로 분류하였다. 실제 수년간 수집한 2명의 통합 개인 이동성 모델을 바탕으로 집단 이동성 모델을 생성한다. 집단 이동성 모델 생성에는 R Language를 사용하였고 결과 모델을 지도상에 표시할 수 있다.

  • This paper proposes an intelligent word cloud by improving the existing method of representing word cloud by examining the frequency of nouns with text mining technique. In this paper, we propose a method to visually show word clouds focused on other parts, such as verbs, by effectively adding newly-coined words and the like to a dictionary that extracts noun words in text mining. In the experiment, the KoNLP package was used for extracting the frequency of existing nouns, and 80 new words that were not supported were added manually by examining frequency.

  • In the current software project, it is still very difficult to extract and define clear requirements in the requirement engineering. Informal requirements documents based on natural language can be interpreted in different meanings depending on the degree of understanding or maturity level of the requirements analyst. Also, Furthermore, as the project progresses, requirements continue to change from the customer. This change in requirements is a catastrophic failure from a management perspective in software projects. In the situation of frequent requirements changes, a current issue of requirements engineering area is how to make clear requirements with unclear and ambigousrequirements. To solve this problem, we propose to extract and redefine clear requirements by incorporating Design Thinking methodologies into requirements engineering. We expect to have higher possibilities to improve software quality by redefining requirements that are ambiously and unclearly defined.

  • The study uses the audited financial statements of 26 Vietnamese commercial banks listed on the Ho Chi Minh City Stock Exchange (HOSE) and Hanoi Stock Exchange (HOSE) during the 2008-2018 period to estimate the system GMM model, which provides empirical evidence on the effect of the variables of customer deposit to total assets (DEPO) ratio, loan to assets (LTA) ratio, liquidity of commercial banks (LIQ), credit development (CRD) ratio, external funding (EFD) ratio, and credit loss provision (LLP) ratio on liquidity risk. The study confirms that commercial banks' internal factors play the most important role, and there is no empirical evidence on macro variables that affect liquidity risk. Finally, in accordance with the theoretical framework, the study uses an estimation method with the R language and the bootstrap methodology to give empirical proof of the nonlinear correlation and U-shaped graph between commercial bank size and liquidity risk. The importance of commercial bank size in absorbing and moderating the effects of liquidity shocks is demonstrated, however, excessive growth in commercial bank size would increase liquidity risk in commercial bank operations.

  • 원어민이 발성한 영어유음 시료를 사용하여 한국인 영문과와 타학과(비 영문과) 학생들을 대상으로 인지실험을 하였고, 시료의 정확성을 확인하기 위하여 원어민을 또 하나의 피험자 그룹으로 선택하였다. 영문과 피험자의 영어유음 인지결과를 살펴보면 어두$(70\%)$ < 어말$(75\%)$ < 어중$(80\%)$ glt; 연속음$(86\%)$의 순서로 인지율이 높아졌다. 타학과 피험자의 영어유음 인지에서는 어두$(59\%)$< 어말$(66\%)$ glt; 어중$(70\%)$ < 연속음$(72\%)$의 순서로 인지율의 증가를 보였다. 원어민의 영어유음 인지에서는 녹음에 참가하지 않은 다른 원어민을 대상으로 해서 총 평균 $99.6\%$로 거의 완벽한 인지율을 보였다. 그 만금 녹음된 시료가 정확하다는 것을 확인시켜 주었다. 피험자별 그룹에 대한 결과 비교에서는 원어민이 녹음한 발음으로 인지실험을 할 때 타학과$(66.8\%)$ < 영문과$(77.4\%)$< 원어민$(99.6\%)$의 순서로 점차 좋은 인지율을 보였다. 한국인이 발성한 영어유음에 대한 원어민의 인지실험에서는 한국인 영어유음 발음의 정확성을 알아보고자 하는 것이 목적이다. 한국인 발성시료에 대한 원어민의 총인지율은 $68\%$로 원어민의 발성시료에 대한 인지율 $99.6\%$와 비교해볼 때 영문과 녹음자들의 발음 정확도가 높지 못하다는 것을 보여 주었다. 평균/1/ $(79\%)$과 평균/r/$(58\%)$의 인지율을 보게 되면 한국인의 영어유음 발성에 있어서 /r/의 발성이 /1/의 경우보다 문제가 더 심각하다는 것을 알 수 있다. 특히 실험결과는 어두/1/$(87\%)$과 어두/r/$(43\%)$에서 뚜렷한 인지율의 차이를 보여주고 있다.
