  • It is often claimed that the descriptive way of documentation is insufficient to define software requirements as being unambiguous. This is caused by not only the difference of knowledge and understanding of the stakeholder as to system but also the difference in the way of documentation like method of representation as well as depth of description. The study explains the process and results of applying a diagraming tool like UML to improve the requirements of GLORY(GLObal Resource management sYstem) initially defined in descriptive way. Especially, the result shows that the requirements are more accurately improved with the good hierarchies and well-leveled functionalities, with the help of diagraming tool, expecting easy maintenance of requirements and prevention of omission of requirements.

  • 본 논문에서는 MPEG-7에 정의된 오디오 서술자를 이용한 오디오 특징을 기반으로 한 음악 검색 알고리즘을 제안한다. 특히 timbral 특징들은 음색 구분을 용이하게 할 수 있어 음악 검색뿐만 아니라 음악 장르 분류 또는 Query by humming에 이용 될 수 있다. 이러한 연구를 통하여 오디오 신호의 대표적인 특성을 표현 할 수 있는 특징벡터를 구성 할 수 있다면 추후에 멀티모달 시스템을 이용한 검색 알고리즘에도 오디오 특징으로 이용 될 수 있을 것이다 본 논문에서는 방송 시스템에 적용 할 수 있도록 검색 범위를 특정 컨텐츠의 O.S.T 앨범으로 제한하였다. 즉, 사용자가 임의로 선택한 부분적인 오디오 클립만을 이용하여 그 컨텐츠 전체의 O.S.T 앨범 내에서 음악을 검색할 수 있도록 하였다. 오디오 특징벡터를 구성하기 위한 MPEG-7 오디오 서술자의 조합 방법을 제안하고 distance 또는 ratio 계산 방식을 통해 성능 향상을 추구하였다. 또한 reference 음악의 템플릿 구성 방식의 변화를 통해 성능 향상을 추구하였다. Classifier로 k-NN 방식을 사용하여 성능 평가를 수행한 결과 timbral spectral feature들의 비율을 이용한 IFCR(Intra-Feature Component Ratio) 방식이 Euclidean distance 방식보다 우수한 성능을 보였다.

  • This study was to investigate the relationship between emotional intelligence and adjustment of college life as well as the effect of emotional intelligence on adjustment of college life in first year nursing college students. The participants were 104 first year nursing college students. Data was collected from June 11 to 13, 2012 and analyzed using descriptive statistics, pearson correlation coefficients and multiple regression. The mean scores for emotional intelligence 3.59 and adjustment of college life 3.01 were above average. A significant and positive correlation was found between emotional intelligence and adjustment of college life. The emotional intelligence predicted adjustment of college life. The strongest predictor on adjustment of college life was emotional recognition and next predictors were in order of empathy and emotional expression among the sub-factors of emotional intelligence. The results of this study suggest that it needs to develop the program for improving the emotional intelligence for better adjustment of college life in college nursing students.

  • The purpose of this research was to investigate the descriptive evaluation method that focuses on the problem solving process of the student. The goal was to evaluate the students' understanding of the subject rather than the students' ability to find the final answer. The descriptive evaluation is being suggested as a way of examining the thought process of the student by performing a structured analysis of the problem solving process. Today, there are not enough descriptive evaluation resources available for teachers to effectively carry out this alternative assessment method in the elementary school mathematics curriculum. This research is a case study on the development of resources for descriptive evaluation in grade 4 mathematics. We designed the development process for descriptive evaluation and its rubric for all 8 units of the 4-Na level of mathematics in the elementary school curriculum. Three descriptive problems were developed for each of the 8 units for a total of 24 problems. The rubric consisted of three areas of assessment, 1) understanding of the problem, 2) problem solving, and 3) mathematical communication. The problems were first pilot tested in two 4th grade classes. Modified problems were then tested in a different 4th grade classroom. The study showed that the three defined areas of evaluation framework (problem understanding, problem solving and mathematical communication) were measurable and analyzable using the developed grading rubric. We then conclude that he descriptive evaluation could be used as an effective tool for improving teacher performance in elementary school mathematics.

  • The purpose of this paper is to examine how European textbooks reflect Seoul nowadays. The study focuses on the trend of textbooks in main European countries, such as England, France, Spain, Italy, and Germany. They tend to describe Seoul as one of the mega cities with urban problems, and introduces the city as an economic center which is responsible for interaction with other mega cities. Besides, Seoul is also described as less competitive city compared to others, and its history and cultural resources are not paid attention. Despite everything, it is fortunate that there are very few errors in descriptions of Seoul. In future I expect that descriptions of Seoul in European textbooks are enhanced in not only economic aspects of Seoul but also historic and cultural aspects of Seoul and then European textbooks get more reliable contents to inform Korea.

  • 우리나라에서는 그동안 급속한 경제발전과 함께 많은 SOC 건설공사가 이루어졌으나 환경성의 고려와 보존에는 미흡하였다. 그러나 경제가 발전되고 국민의 의식수준이 향상됨에 따라 환경에 대한 관심과 중요성이 높아졌으며, 친환경적인 건설의 요구가 증대되고 있다. 이러한 추세에 따라 친환경 건설을 위한 많은 연구와 노력들이 진행되고 있지만, 타 분야에 비해 정보화 및 전산화, 특히 GIS의 활용은 많이 미흡한 실정이다. 따라서 본 연구에서는 초기 건설계획 및 설계분야에 최신 GIS 기술을 접목ㆍ활용함으로써 환경성이 고려된 국토개발을 지원하고자 하였다. 이를 위해 도로건설분야를 대상으로 하여 다양한 대안노선들의 환경성을 비교ㆍ검토하여 최적의 노선선정을 지원하고, 선정된 노선에 대하여 영향평가분석을 수행할 수 있도록 시범시스템을 개발하였다. 기존의 환경성 검토ㆍ평가방법이 종이도면과 서술적인 기술에 의지했던 반면, 본 시스템은 수치지도 및 위성영상을 활용한 다양한 GIS 공간분석결과를 2차원 또는 3차원적으로 디스플레이하여 객관성과 효율성을 향상시키면서 시각적 효과를 높여줄 수 있다는 장점이 있다.

  • This investigation reviewed 74 studies related to pregnancy and childbirth of married immigrant women that were selected from national dissertations and others in journals released in the past 10 years from 2007 that were identified using http://www.riss.kr. Analysis on the trend of research was done through result variances used in academic fields, planning researches, main themes and mediative studies. Of the 74 studies, 28 were national dissertations (38.6%) and 46 were articles in academic journals (61.4%), 37 of which were performed by nursing departments (50.0%). Additionally, 45 were quantitative (60.8%) and 29 were qualitative (39.2%) and descriptive research, and 22 in total(29.9%) took the most of the part of quantitative research. Key concepts were categorized into nursing, environment, health, and humans, which are the paradigms of nursing, while papers in all other categories were categorized as etc. Most themes of research were based on social psychological aspects of the health domain and the human domain. Among the eight mediative research studies, seven focused on postnatal married immigrant women and the remaining one focused on postnatal married immigrant women and infants. In the categorized research planning quantitative research took larger part than qualitative research and in quantitative research descriptive study took larger part than experimental research. In the case of experimental research, studies usually focused on married immigrant women who had experienced pregnancy and childbirth. Overall, the results indicated that development and provision of new nursing mediation programs are needed, not only for married immigrant women, but also for their families.

  • Although the table, as one of the representations for helping mathematics understanding, steadily has been shown in the mathematics textbooks, there have been little studies that focus on the table and analyze how the table may be used in understanding students' functional thinking. This study investigated the elementary school 5th graders' abilities to design function tables. The results showed that about 75% of the students were able to create tables for themselves, which shaped horizontal and included information only from the problem contexts. And the students had more difficulties in solving geometric growing pattern problems than story problems. Building on these results, this paper is expected to provide implications of instructional directions of how to use the table as 'function table'.

  • This descriptive study investigated the factors influencing on subjective happiness of senior nursing students. The participants were 235 nursing students in grades 3 and 4 in K city from May 1, 2019 to May 28, 2019. The data was collected using self-report questionnaires that contained items on subjective happiness, professional intuition, human relationship, major satisfaction, family health, and social support scale. The data was analyzed using descriptive statistics, Pearson's correlation coefficients, and stepwise multiple regression analysis with the SPSS 22.0 program. The subjective happiness of the subjects averaged 4.75±1.16 on the 7-point scale, and the subjective happiness according to the general characteristics of the subjects showed a significant difference in health status (F=6.826, p<.001). The most influential factors on the subjects' subjective happiness were health status (β=.177 p=.005), academic satisfaction (β=.138, p=.027), and family health (β=.268, p<.001), and the explanatory power of the model was 16.7% (F=15.160, p<.001). The results of this study may provide a foundation to develop an efficient intervention program to improve the happiness of senior nursing students.
