Expenses in the form of personnel expenses in the past, in modern times, machine guards to gradually transition has been. This is because the machine guard is more efficient than personnel expenses. But due to false alarms, despite the high expectations of the effects of electronic security in the operation of the electronic security system due to factors that hinder the development of machine guards growth slows. Defect removal aspects of this paper, using IPA (Importance Performance Analysis) techniques to study the operation of electronic security systems and its importance in the development of machine guards, look at how high the technical aspects of electronic security systems composite type of malfunction to minimize crime sensor are presented.

최근 문제해결능력향상을 위해 대학에서는 PBL 교수법(Problem-Based Learning)을 도입하고 있으며 국가 차원에서도 이를 장려하고 있다. 본 연구는 국가직무능력표준(NCS)의 직무능력단위 중 하나인 문제해결능력을 향상시킬 수 있는 효과적인 수업방법을 모색함과 동시에 교육현장에서 직면할 수 있는 문제를 합리적으로 해결하는 학습자 능력 신장을 위해 PBL수업을 활용하였다. 이에 본 연구는 문제중심학습법을 대학 영어전공 교과목에 적용함으로써 대학생의 창의적 문제해결력과 수업참여도에 대한 효과를 살펴보는데 연구의 목적이 있다. 본 연구는 사전검사, PBL수업 운영, 사후검사의 3단계로 진행된다.

The purpose of this study is to explore how units-coordination ability is related to understanding fraction concepts. For this purpose, a teaching experiment was conducted with one fourth grade student, Eunseo for four months(2019.3. ~ 2019.6.). We analyzed in details how Eunseo's units-coordinating operations related to her understanding of fraction changed during the teaching experiment. At an early stage, Eunseo with a partitive fraction scheme recognized fractions as another kind of natural numbers by manipulating fractions within a two-levels-of-units structure. As she simultaneously recognized proper fraction and a referent whole unit as a multiple of the unit fraction, she became to distinguish fractions from natural numbers in manipulating proper fractions. Eunseo with a reversible partitive fraction scheme constructed a natural number greater than 1, as having an interiorized three-levels-of-units structure and established an improper fraction with three levels of units in activity. Based on the results of this study, conclusions and pedagogical implications were presented.

In this study, the effects of writing a weekly report on the students' self-directed learning, the attitudes toward science, and the academic achievements were examined. Two hundred and three students, second graders of a high school participated. Experimental group performed writing a weekly report, while the comparative group performed regular science lessons. The results of this study are as follows: First, MSLQ test showed that there was statistically significant difference in the self-directed learning skills(p<.05). For sub-factors of motivation region, such as internal goals, extrinsic goals, learning beliefs, task value, and self-efficacy and for sub-factors of learning strategy region, such as meta-cognition, peer learning, time management, critical thinking, and demonstrations showed statistically significant results. Second, TOSRA test showed that there was no statistically significant difference in the attitudes toward science (p>.05). However, for sub-factors, such as scientific inquiry and joy to science class showed statistically significant results. Third, there was no statistically significant difference in the academic achievement in Chemistry I class (p>.05). However, top and low achievement level showed statistically significant results.

The Standardized Precipitation Index (SPI) is widely applied to evaluate for meteorological droughts. However, the SPI is limited to capture a drought event with a short duration, expecially shorter than one month. In this study, we proposed a daily SPI (DSPI) as a way to overcome the limitation of the monthly SPI for drought monitoring. In order to objectively assess the ability of the drought reproduction of the DSPI, we performed a receiver operating characteristic (ROC) analysis using the quantified drought records from official reports, newspapers, etc. The results of ROC analysis showed that the DSPI has an ability to reproduce short-term drought compared with other indices. It also showed that the main cause of historical droughts was the shortage of rainfall accumulated during the time period less than 90 days compared with the rainfall of normal years.

현재 한국어 의존 구문 분석의 표준은 어절 단위로 구문 분석을 수행하는 것이다. 그러나 의존 구문 분석의 분석 단위(어절, 형태소)에 대해서는 현재까지 심도 있는 비교 연구가 진행된 바 없다. 본 연구에서는 의존 구문 분석의 분석 단위가 자연어 처리 분야의 성능에 유의미한 영향을 끼침을 실험적으로 규명한다. STEP 2000과 모두의 말뭉치를 기반으로 구축한 형태소 단위 의존 구문 분석 말뭉치를 사용하여, 의존 구문 분석기 모델 및 의존 트리를 입력으로 활용하는 문장 의미 유사도 분석(STS) 및 관계 추출(RE) 모델을 학습하였다. 그 결과, KMDP가 기존 어절 단위 구문 분석과 비교하여 의존 구문 분석기의 성능과 응용 분야(STS, RE)의 성능이 모두 유의미하게 향상됨을 확인하였다. 이로써 형태소 단위 의존 구문 분석이 한국어 문법을 표현하는 능력이 우수하며, 문법과 의미를 연결하는 인터페이스로써 높은 활용 가치가 있음을 입증한다.

This study analyzed the problems of skin beauty textbooks used in high school based on the NCS ability unit, and was to improve them. By the NCS standard, it focuses on the contents which can be learned during the high school course. The main results are as follows. First, the revision of textbooks is to contain NCS competency unit, which is excluded in spite of being taught. Second, Replacement is required for NCS 5 level beyond the high school. Third, the illustrated and photographic materials is revised to improve the understanding by maintaining consistency and visibility. Fourth, the contents on the practical skill need specific explanations and instructional materials. Fifth, to revise terminology and the notation system is needed in skin care. The results of this study can be used as basic data to develop an NCS learning module in the skin care field and high school textbooks.

최근 국내 신입사원 입사시험에 NCS 직업기초능력시험을 도입함에 따라 국내 각 대학교나 교육기관에서는 NCS 기반의 전공교육 및 교양교육을 도입하고 있다. 이에 따라 프로그래머를 지향하는 공학도를 위한 NCS 기반 프로그래밍 능력을 향상시켜줄 수 있는 교수-학습 지침안이 필요하게 되었다. 본 연구에서는 학습 모듈을 도출하기 위한 분석과정을 거쳐 본 교과의 학습로드맵과 NCS능력단위요소를 기반으로 학습자 스스로 NCS 프로그래밍 능력을 향상시킬 수 있는 교수-학습 모듈을 설계하였다.

South Korean Government confirmed the creation of competency-centered society as a key national issue and announced development and utilization plan of NCS(National Competency Standards) On May 21, 2013. As a part of the government's plans, they had been developed NCS about 833 jobs by 2014. But Big Data related job, as an emerging job, cannot be seen as a reliable form of job yet. As, at the major industrialized countries and the domestic, education and job competency models of knowledge and skills to take advantage of various types of Big Data have coming, it is a situation that is certainly not settled and more or less in confusion. In this study, for the purpose to present the Big Data Competency reference model for companies and organizations to effectively leverage Big Data, we have presented this reference model and summarized competency elements units such as 20 knowledges and 15 skills of Big Data competency.

The purpose of this study was to analyze the functional unit system of NCS landscape field for correction and supplementation of NCS landscape field and the contents of the four-year college landscape course subject. First, 24 unconsolidated four-year universities were selected, and FGI was conducted and verified for 816 courses in 24 universities. The results of the study are summarized as follows, with three sections three, nine divisions and 65 sub-category. First, landscape design subjects accounted for 40.0% of the subjects organized by four-year universities. In addition, the ratio of 12.9% for ecological landscape, 11.3% for landscape construction, 10.2% for others, 10.0% for landscape information, 6.6% for landscape culture and 3.7% for landscape management was surveyed. Balanced and efficient modification and reinforcement of NCS is required in the future. Second, 10(18.9%) units with matching NCS performance criteria and educational objectives were found to be capable of different units(18.9%), 15(28.3%), and 37subjects with inconsistent NCS unit capability (56.9%). Third, looking at the criteria for the reference of each unit of capability presented by the NCS, it is deemed that one unit of capability should be organized separately to improve the practical ability, since it includes the contents of basic knowledge learning. Fourth, the objectives pursued on the basis of the contents of the NCS capability unit and four-year college curriculum were developed by focusing on the development of unit capabilities in the field of landscape construction and landscape management compared to the field of landscape design. It has been shown that a balance is needed for future development. This study is intended to put forward further research that re-examine specific curriculum assessment criteria that have not been classified in the course of classifications based on the curriculum handbook, which excludes interferences from each school.
