  • 인터넷 웹 기반 교수-학습체제는 학습자 위주의 교육환경으로 변화하였고, 웹 환경에서도 학습자에게는 시간과 공간의 제약에서 벗어나 다양한 교육정보를 접할 수 있는 원격교육시스템이 대두하고 있다. 인터넷의 발달은 교육환경에도 많은 변화를 가져오고 있다. 이러한 변화는 인터넷을 이용한 웹기반 원격교육이 여러 분야에서 폭넓게 응용되고 있음을 대변하는 것이라 할 수 있다. 하지만 기존의 원격강의시스템의 경우 교사가 학습할 내용들을 파일형태로 업로드해 놓으면 학습자가 다운로드하여 쓰는 방식이어서 많은 전송비용과 강의내용 구성이 단순한 텍스트 위주의 형태로 구성되어 학습자의 학습효과가 의문시 되었다. 이는 학습자 위주의 자기 주도학습에 많은 어려움을 유발시켰다. 따라서, 본 논문에서는 고등학교 정보산업교과의 [인터넷] 단원에 대한 학습을 체계적으로 언제 어디서나 학습할 수 있도록 이론과 실기강의내용을 웹을 통하여 교육에서 요구되는 음성과 교재 판서의 기능을 웹상에서 구현할 수 있도록 되어 있다. 이런 멀티미디어 자료들이 동기화되어 자기 주도적 학습을 할 수 있는 멀티미디어 원격강의시스템을 구현하였다. 본 연구의 원격강의시스템은 멀티미디어자료 들을 활용한 원격강의시스템이기 때문에 개별화된 교육과 자기 주도적 학습을 통해 시ㆍ공간의 제약을 받지 않고 학습 할 수있는 진정한 원격강의시스템이다.

  • This study was conducted to evaluate the effects of a Motivation Enhancement for Smoking Cessation Program on middle school students' knowledge regarding smoking, self-efficacy, and daily amount of smoking. The study used a nonequivalent control group pre-post-test design and included 47 students who smoke from two middle schools located in city U as subjects. Subjects were separated into two groups, an experimental group with 23 students and a control group with 24 students. Data were collected from February 19, 2018 to May 11, 2018 and analyzed using the IBM SRSS/win 24.0 program to conduct a t-test, ${\chi}^2$-test, Fisher's exact test, and a paired t-test. After subjects went through the Motivation Enhancement for Smoking Cessation Program, their knowledge regarding smoking (t= 3.38, p=0.002), self-efficacy (t= -3.37, p=0.002), and their daily amount of smoking (t=3.38, p=0.002) showed significant changes. The results indicate that the Motivation Enhancement for Smoking Cessation Program is effective at increasing subjects' knowledge regarding smoking and self- efficacy while decreasing their daily amount of smoking. Therefore, to induce cessation of adolescent smoking, Motivation Enhancement for Smoking Cessation Programs tailored to each student should be held.

  • 농촌인구의 급격한 감소와 고령화 속에서 농촌의 지속가능성을 위한 방안으로 귀농·귀촌의 확대가 부각되고 있다. 본 연구는 귀농·귀촌인의 생활만족도 결정요인을 분석함으로써 도시민의 농촌 이주와 성공적인 정착을 촉진하기 위한 정책적 시사점을 제공하고자 한다. 본 연구는 특히 귀농·귀촌의 주요 동기가 소득이나 농촌의 자연환경이라는 점에서, 생활만족도를 자연환경만족도와 소득만족도로 구분하여 비교 분석하는 데 목적이 있다. 분석에는 순서형 로짓모형과 일반화 로짓모형을 사용하였고, 분석자료는 2016년 「귀농귀촌실태조사」 원자료이다. 분석결과, 귀농·귀촌인의 자연환경만족도는 상당히 높으나 소득만족도는 보통 수준에 미치지 못하였다. 귀농·귀촌의 이유가 자연환경이거나, 귀농·귀촌 시 가족의 지지가 있었거나, 귀농·귀촌 이후 주변 이웃들과 좋은 관계를 유지하거나, 지자체로부터 귀농·귀촌 지원을 받은 경우, 귀농·귀촌인의 소득만족도와 자연환경만족도가 모두 높았다. 이러한 공통적인 요인 이외에 귀농·귀촌인의 소득만족도와 자연환경만족도에 영향을 미치는 요인은 뚜렷한 차이를 보였다. 소득만족도는 현재 가구소득이나 귀농·귀촌 전·후 소득 변화와 같은 경제적 요인에 의해 영향을 받으나, 자연환경만족도는 귀농·귀촌 시 배우자의 동행 여부나 지역사회 참여와 같은 사회적 요인에 의해 주로 영향을 받는 것으로 나타났다.

  • The characteristics of storm and water quality are investigated based on the measuring data of the test river, the Hongje. the water quality of the test river is generally good comparing to other urban rivers in Seoul, because of the interception of sewer flow. But this system makes the river dry up for 3-4 months in winter. On the other hand, in rainy period the storm from the combined sewer system causes rapid increasing pollutants loads. In order to simulate the urban storm and water quality of the trest basin, the models such as SWMM, ILLUDAS, STORM, HEC-1 were applied and the results are compared in its applicability and accuracy aspects. All models discussed here have shown good results and it seems that SUMM is the most effective model in simulating both quantity and quality. Also, regression relations between the water quantity and quality were derived and their applicabilities were discussed. This regression model is a simple effective tool for estimating the pollutant loads in the rainy period, but if the amount of discharge is bigger than measuring range of raw data, the accuracy becomes poor. This model could be supplemented by expanding the range of collecting data and introducing the river characteristics. The HEC-1 would be anther effective model to simulate storm runoff of a river basin including urban area.

  • This study has analyzed the factors that influence the safety consciousness of elderly drivers. To achieve this, 307 elderly who drives commercial and non-commercial in Daejeon, Sejong, Chungnam and Chungbuk area were selected as study subjects. For the data analysis, PASW Statistics 18.0 was used. The main results of this study are as follows. The level of safety consciousness of commercial and non-commercial drivers were 6.49 and 6.93 respectively showing that drivers of non-commercial were significantly higher. Second, the factors that influence the safety consciousness were shown to be significantly different for each group. The factors that influence the safety consciousness of commercial drivers were shown in the order of safety-seeking motivation, economic status, daily driving hours, sensation-seeking disposition. The factors that influence the safety consciousness of non-commercial drivers were shown in the order of safety-seeking motivation, health status, whether or not the accident was experienced, sensation-seeking disposition. Based on these results, several ways were suggested to improve the safety consciousness of elderly drivers and prevent the traffic accidents.

  • 회전 기기의 이상으로 인하여 발생하는 진동은 축 회전속도의 고주파 성분 (super-harmonic)이나 또는 분수조파 성분(sub-harmonic)으로 나타나는 경 우가 대부분이기 때문에 회전기기의 진동을 주파수 영역에서 해석함에 있어 파워 스펙트럼의 주파수 축을 Hz로 나타내기보다는 축 회전속도의 order로 써 나타내는 것이 매우 유용하다. 스펙트럼을 order로써 나타내기 위해서는 샘플링 시간을 축 회전속도와 동기(synchronization)시켜야 하는데 이 방법으 로는 회전축에 엔코더(encorder)를 부착하여 엔코더에서 발생하는 펄스 신호 를 이용하여 샘플링하는 방법과 order tracking 필터를 이용하는 방법이 있 다. 그러나 전자의 방법은 원하는 회전축마다 엔코더를 부착하여야 하며 경 우에 따라서는 엔코더를 부착하기가 어려운 경우도 있으며, 회전기기의 운전 개시나 종료시처럼 회전속도가 급격히 변화하는 경우에는 낮은 주파수에서 중첩(aliasig)에 의한 오차가 수반될 수도 있다. 후자의 방법은 order tracking 필터 이외에도 여러 부수장비가 필요하며 기준 주파수(즉 회전속 도)가 급격히 변화하는 경우 PLL(phase locked loop)에서 tracking 오차가 발생된다. 최근에 발표된 논문에서 일정한 시간간격으로 샘플링한 데이터들 로부터 신호를 재합성하여 회전축의 속도와 동기가 되도록 재 샘플링함으로 서 스펙트럼의 주파수를 회전속도의 order로써 나타내는 방법을 제시하였다. 그러나 위 논문에서는 신호의 재합성에 필요한 재합성 필터(reconstruction filter)의 설계 방법에 대하여 구체적인 언급이 없이 다만 결과만을 논하였다. 따라서 본 논문에서는 재합성 필터의 설계 방법에 대하여 구체적인 방법을 제시하고 또한 동기화 샘플링의 장점 및 고려 사항에 대하여 고찰하였다. 고려한 능동 소음제어 에 대해 연구하였다. 경량화 추세에 따라 지반이나 케이싱이 경량이거나 유연하여 회전축과 동적으로 연성된 경우 회전축-베어링-지반으로 이루어진 2중구조의 회전축 계 동특성을 해석할 수 있는 프로그램을 개발하므로서 회전 기계류의 진동 전반에 걸친 문제점에 대한 그 원인과 현상을 명확히 분석하여 국내의 전기 계류의 보다 신뢰성있는 설계 및 제작자료를 확보하는데 기여할 수 있게 하 였다.존의 small molecular Gd-chelate에 비해 매우 큼을 알 수 있었다.

  • This study was to assess the effects of a recovery oriented integrated rehabilitation program on cognitive social function, rehabilitation motivation, and mental health recovery. This program is involved motivation enhancement program with 4 subprograms composed of cognitive rehabilitation, emotion management, vocational rehabilitation, family education program. The subjects were 34 patirents with schizophrenia who had been hospitalized at National Mental Hospital on local area. The study was a non-equivalent control group non-synchronized design with two groups, an experimental group(18 patients) and a control group(16 patients). The collected data were analyzed using SPSS 12. 0. The results of the data show that there was not a significant increase in the symptom, cognitive and social function. But there was a significant increase in readiness of rehabilitation(maintenance, p=.027) and mental health recovery (p=.039). Short term recovery oriented integrated rehabilitation programs in inpatient settings are more available for motivation of rehabilitation and mental health recovery than symptom reduction or functional improvement. Therefore there should be more efforts to create more recovery oriented service provision in clinical settings.

  • This study presents how the engineering ethics instructional modules have been developed based on Korean culture and how they are implemented into the existing engineering curricula at Sungkyunkwan University. The engineering ethics instructional modules were designed to be taught by engineering faculty members who did not have any teaching experience in ethics. As a result, it was determined that the engineering ethics instructional modules should include a detailed instructor lesson plan and all supporting resources such as slides (Power Point base), and handouts, or assessment units (pre- and post-test). Two 75 minute modules developed in this study consist of the diverse instructional activities for various student group sizes. In order to improve students' interests and classroom attention, various visual and audio resources such as famous movies, cartoons, and poems were included in the instructional resources. In addition, a number of case studies which might happen in the students' daily lives were chosen. The resulting ethical module No. 1 has been instructed in the existing engineering classes during the 1st semester in 2007. Overall, the students reported positive impressions of the modules and the faculty members also reported favorable perceptions of the modules. Also, team based activities encouraged students to participate in constructing the event trees, which are a basic analysis tool for ethics case studies. The results of this study will provide a guideline of implementing engineering ethics into the engineering curricula to other engineering programs and schools.
