Seismic station of high noise level has difficulties detecting relatively weak ground motions due to small earthquakes or teleseismic events because earthquake detectability of seismic station depends on seismic noise level. To figure out the capability of earthquake detection of a seismic network, therefore, seismic noise level of each station also needs to be considered, including the distribution of seismic stations. Recently, it has been known that most of broadband seismic stations in South Korea have affected by cultural noise in the frequencies higher than 1 Hz and show diurnal variations of noise level. In order to analyze the effect of diurnal variation of seismic noise level on earthquake detectability, we used the result of background seismic noise level analysis of seismograms of 30 broadband stations of KIGAM and KMA from 2005 to 2007. This study shows that earthquakes greater than magnitude 2.4 occurring within the Korean Peninsula can be detected at night while those greater than magnitude 2.6 can be detected in the daytime.

This study investigates how domestic entertainment companies' CSR activities, risk management, and producing abilities affect consumers' perception of their integrated brand assets. A survey was conducted on college students enrolled in a four-year university, and a total of 423 data were used for analysis. The result indicates the following. First, consumer evaluation of economic activity and philanthropic activity showed a positive causal relationship with the perception of integrated brand assets. Second, the higher the risk management and producing ability on evaluation of entertainment companies, the more positive the perception of integrated brand assets. Third, the main effect of producing ability was found to be significant among the four companies. In addition, regardless of the evaluation level of CSR activities and risk management, the group with a high producing ability evaluation showed a higher perception of integrated brand assets than the group with a low level of evaluation.

The purpose of this study was to analyze 'how STEAM activities affect students' science process skills and science-related attitudes'. For more accurate, we have set 31 sixth-grade students from Gyeong-gi Province as an experiment group, and another 31 as a comparative group. We developed a STEAM program based on the educational concepts: Creative Design and Emotional Touch. Through pre-post experiment design, we have introduced TSPS, and Test of Affective Aspects. For TSPS, the comparative group scored higher average grade before the process. After the process, however, the experiment group exceeded the other. The result was considerable enough to verify that the science process skills were bolstered through the STEAM program(p<.05), Similar result was derived regarding the science related attitude. Students in the comparative group originally showed higher degree of interest to science. When the STEAM program was carried out, the standing reversed. The increase in the number of science related attitude indicates the program valid(p<.001). Furthermore, when we asked the students who participated in the experiment how they recognized the STEAM activity, we received positive answers: they consider the program efficient and well suited to the class environment. Conclusively, the STEAM program was proven to be effective for improving science process skills and attitude, and was perceived affirmative.

필자들은 제37회 교육자료전시회(1997)와 제38회 교육자료전시회(1998)에 작품을 출품하였다. 이들 교육자료전시회에 참가하게 된 동기는 다음과 같다. 입문기 아동의 수학교육은 학습내용에 대한 흥미를 가지도록 해야 하며 구체적인 조작활동을 통하여 수량에 대한 기초적인 개념과 원리, 그리고 법칙을 바르게 이해시켜 논리적 사고력을 기르도록 해야 한다. 그러나 대부분의 아동들을 목표수준에서 보면 만족스럽지 못하고, 시간이 지날수록 학습결손아가 늘고 있는 현실이다. 특히 오름길 학습지를 해결할 때는 우수한 아동에게도 조작활동을 시켜보면 뜻밖에 조작 활동을 제대로 못하고 당황하는 경우를 흔히 볼 수 있다. 이것은 개념 형성과 개인간의 차에 관심을 둔 지도가 이루어지지 않은 상태에서, 자기능력과 수준에 맞는 학습을 하지 못하고 다음 단계로 넘어가기 때문이라 판단하였다. 이에 필자들은 교과서에 예시한 활동이나 그림 자료들을 실제로 관찰하고 조작해 볼 수 있도록 구체적인 자료로 대체하여, 수학에서 요구하는 학습지도 원리에 적합하도록 하였다. 또 교실 수업에서 야기되는 개인차에 대한 학습지도상의 문제점을 해결하는 한편, 급우간 인간관계에 바탕을 둔 소그룹 협동 학습을 위한 자료로 수와 가감산의 원리를 쉽게 체득 시킬 수 있도록 하였다.

This paper studied the improvement of software process of the software firms. Software process infrastructure level of software process is very important. This study provided that software process infrastructure have an significant influence on the process level, process infrastructure management level, and software process performance. The result showed that software process high level is elevated through management activity of organization infrastructure and technical infrastructure. And organization performance is elevated through fit between process level and quality culture of software process. Problem factors of software process infrastructure improvement is lack of process improvement mind, leadership and investment. Therefore software firms must construct process improvement through supporting of process quality mind and investment with process infrastructure improvement.

The purpose of this study was to identify the factors influencing insufficient physical activity in older cancer patients. Data were analyzed from the 2014 Survey of Living Condition of Elderly study. Metabolic Equivalent Tasks(MET) hours were calculated using self-reported weekly frequency, duration and types of physical activities to measure the degree of physical activity. Factors influencing insufficient physical activity in older adults included limitations in ADL and IADL, depression, impaired cognitive function, current smoker, lower levels of social activity participation and life satisfaction with social or leisure activities. When adjusted for demographic factors, patients with ADL limitation had 2.8 times (OR=2.762, CI=1.110, 7.952) higher risks of insufficient physical activities than those without. Current smokers had 2.4 times (OR=2.426, CI=1.113, 5.288) higher risks than non-smokers.

The purpose of this study was to investigate physical activity level, sleep quality, attention control, and self-regulated learning along to smartphone addiction level among college students. The data were obtained from 269 college students by structured questionnaire, analyzed using SPSS 18.0. The results showed that significant differences with smartphone addictoin level and, gender, grade level, daily using time, physical activity level, sleep quality and attention control. Smartphone addictoin level have correlations with physical activity level, sleep quality, attention control, and self-regulated learning. To prevent the falling off of physical strength and poor school performance, it is needed a strategies for control of smartphone addiction.

The purpose of this study was to investigate middle school student's self-directed learning(SDL) using a hierarchical linear modeling. By considering variances of SDL at individual and school level, the student's SDL was explained in terms of school quality as well as individual efforts. For the HLM analysis, participation in private tutoring, teacher's support for SDL, caring students' individual needs, and participation in extra curriculum activities were explored at individual level. At school level, school SES, quality of national curriculum implementation, and parental support for school were utilized. The results of analysis showed that more than 95% of variance of SDL was explained by variables at individual level. Among the variables at individual level, private tutoring was not a significant variable explaining the SDL. Based upon the results, multiple regression analyses by background variables were also conducted. By interpreting the results of analyses, the impact of school quality and individual efforts on the SDL was discussed.

대부분 학습용 코스웨어는 CD타이틀로 구성되어 전형적인 일대일 학습 형태를 띄고 있어 학습자에게 금방 지루함을 느끼게 하기 쉽다. 또한 인지적 능력이 부족한 초등학생에게 단순한 교과서식의 웹코스웨어를 적용하는 것은 학습 효과를 높이는데 한계가 있다. 본 논문에서는 초등 교육 현장에 웹을 활용하여 아동들의 다양한 협력 활동을 통해 정보를 탐색하고 조사 활동을 할 수 있는 초등학생 수준에 맞는 협력 학습을 위한 웹기반 사이버학습 교재를 개발 적용한다. 이를 활용하여 교과 시간은 물론 일상 생활에서도 주어진 과제 해결에 필요한 정보 자료를 수집, 분류하고, 웹기반에서 토론하여 일반화된 결과를 도출해 내어 문제 해결 능력을 신장시키는 자료를 개발하였다.

Ability to find some information is the basic ability in information making activity. Even though students have been instructed how to search information, however, they don't reach a certain level. For improving ability to make information, it needs to be connected to Korean and Social education. Therefore, this paper analyzes the contents of related-subjects to internal and external curriculum of computer education, and develops the program to improve ability to make information, selecting learning point for improving ability to make information.
