This study purported to study the uses of information and communication technology (ICT) tools in their daily life among the undergraduate and graduate students majoring science and engineering. It also examined the purposes of the uses of the major ICT tools, the differences in their information technology uses between graduate and undergraduate students. The data were collected from 83 undergraduate and graduate students from four universities using content analysis of an observational logs and a survey questionnaire. The observational logs were collected using an instant message application available on a smart phone. Study results revealed desktop computers, laptop computers, and smart phones as the three most heavily used ICT tools among the participants and typical situations students use each of the three tools. There were also sharp distinctions between graduate and undergraduate students in their selection of the tools, and distinctions between work and non-work situations. The findings of this study can be used to redesign information services and systems for the scientists and engineers in the next generation.

This study was conducted to identify the related factors of cancer preventive behaviors for adolescent smokers. Data were collected from September 1st 2012 to March 31st 2013 of 200 adolescent smokers who were participating in smoking cessation school at W hospital in B city. As a results, there were significant differences in cancer preventive behaviors by grade, religion, benefit, barrier, perceived health status, daily living, alcohol, exercise, nicotine dependency, first smoking age, smoking duration and non-smoking intention. Cancer preventive behaviors were weakly negative related to knowledge about cancer, And there is weakly positive correlation between cancer preventive behaviors and attitude about cancer. Meaningful variables which explain cancer preventive behaviors were daily living, barrier, grade, exercise, benefit, knowledge about cancer, smoking cessation intention in order. Total explanation power was 30.6% and daily living has most explanation power. In conclusion, It is necessary to encourage sound hobbies and exercise instead of smoking for adolescent smokers in their daily living. And health education programmes, based on the grade and smoking cessation intention of adolescent smokers, need to be developed to emphasize the benefit of cancer preventive behaviors, and to decrease barriers against those behaviors.

This study aims to provide basic data on socioeconomic and social activities from the point of view that disability or disease accompanying the suffering of industrial accident subjects is directly related to individual socioeconomic activity and is a major variable affecting current health and daily life satisfaction. The purpose of this study is to investigate the relationship between pain and life satisfaction and to suggest basic data for economic and psychological rehabilitation of industrial accident insurance beneficiaries by linking factors affecting life satisfaction with industrial accident services. As a result of the study, it was found that workers' compensation insurance benefit recipients had an effect on their daily life satisfaction after becoming an industrial accident patient due to industrial accident pain. There was a positive(+) relationship between rehabilitation services and medical counseling services. Occupational accident pain lowers self-esteem, which is a characteristic of an individual, and even if current health improves, satisfaction with daily life decreases. The importance of industrial accident-related services can be seen in that the satisfaction of daily life is increased through rehabilitation services and medical consultation services. In addition, it was indirectly confirmed that satisfaction with rehabilitation services and health can be improved as a result of continuing attempts to improve self-esteem suitable for patients in various problems and situations after an industrial accident.

The subjects of this study were 463 people aged 65 and older in the senior welfare center in Seoul and Gyeonggi. The purpose of the study is to analyze the differences between physical fitness factors and cognitive functions, activities of daily living, instrumental activities of daily living, and psychological variables in the participation of the elderly in physical activities. Data ware analyzed by frequency analysis, reliability analysis, independent sample t-test and one-way ANOVA, and Pearson's correlation analysis, with SPSS 25.0 statistics program. The results of this study are as follows. First, there are statistically significant differences in physical fitness, cognitive function, activities of daily living, instrumental activities of daily living, and psychological factors such as depression and quality of life, depending on whether the elderly participate in physical activity. There were statistically significant differences in physical fitness, cognitive function, ADL, IADL, depression and quality of life, depending on the frequency of participation of older people in physical activity. A statistically significant difference in physical fitness appeared depending on the participation time of the elderly who participated in physical activity. Second, a study of the correlation between physical fitness and cognitive function, ADL, IADL, depression, and quality of life revealed a correlation for most factors. Based on these research results, it is necessary to develop a systematic arbitration strategy including physical activity for the successful aging of the elderly and the independent life of old age.

모든 과학기술지식은 객관성을 지닌 관찰과 실험과 측정에 의해서 이루어진다. 이렇게함으로써 과학기술지식은 재현성과 영구성을 가져오게 되며, 올바른 전승과 누적적 발전을 가져오는데 이 과학기술지식의 질서체계를 유지하는데 근본적인 역할을 하는 것이 표준이다. 시간, 길이, 온도, 무게 등의 기본 측정단위와 광속, 중력 등의 물리화학적 상수, 법정계량단위, 각종 공업 규격, 안정 규정 등 수 없이 많은 표준은 효과적인 공동 인식과 객관적 판단의 기준으로 활용되고 있다. 현대의 과학기술이 다양하게 발전하고 이에 따라 우리의 생활도 더욱 복잡한 구조를 이루면서 표준에 대한 필요성도 더욱 높아가고 있다. 표준에 대한 깊은 생각없이도 우리는 자동차에 주유할때 표준단위를 통해 원하는 분량을 말하며, 카메라의 필름 종류를 선택할 때도 국제표준기구(ISO: International Standards Organization)의 규격을 사용하는데 익숙해져 있다. 이렇게 표준은 우리 일상생활과 밀접한 관계에 있으나 소비자 입장에서는 그 가치를 절실히 느끼지 못한 것이 사실이며 표준이 없음으로 해서 일어나는 불편과 혼란에 대해서는 무관심한 것이 사실이다. 일상생활에서 일어나는 표준의 역할을 우리가 잘 이해한다면 표준이 왜 필요한가를 쉽게 인식하게 될 것이다. 최근 정보산업이 새로운 물결로 사회전반에 영향을 미치고 있으며 이에 따라 정보의 수집, 가공, 저장 및 배포의 처리 과정에서도 제반 표준화의 필요성이 크게 대두되었다. 그 결과로 최근 10여년간에 수백종의 기술기준, 지침서 및 기본/기능 표준규격이 제정되어 왔다. 이와 같이 어떤 특별한 영역에서의 표준에 대한 요구가 있을 때 관련 규격이 제정되게 된다. 표준의 제정을 위한 다음 단계는 그 주제에 관한 표준(또는 규격)개발에 관심을 가진 사람들이 모이는 일일 것이다. 통계분야에서도 몇가지 표준화 활동이 ISO 를 중심으로 진행되고 있다. 예를 들면 실험과 검증 결과의 표현과 해석, 표본추출 방법 등에 관한 것으로 이들은 통계의 응용분야에서 꼭 필요한 표준이다. 구체적인 예로서 우리나라 국민의 표준체위값을 설정하기 위하여 측정조사할 때 측정방법 뿐 아니라 표본추출 방법과 통계자료 처리과정의 표준화가 이루어 지지 않는다면 각 기관에서 조사 발표하는 체위관계 자료가 상이하여 국가기관의 통계자료에 대한 신뢰성이 저하되고 통계값을 이용하여 의류, 신발 등의 제품을 제조하는 산업계에 혼란을 야기시킬 수 있다. 본 고에서는 ISO의 활동을 정보처리 분야에 초점을 맞춰 간략하게 설명하고 통계분야의 국제 활동을 비전문가인 필자들이 아는대로 소개하는 한편 국내활동의 필요성을 강조하여 관련 기관, 학계 및 산업계 관련전문가들의 ISO 국내활동 참여를 제의하고자 한다.

At the current camera-based technology level, sensor-based basic life pattern recognition technology has to suffer inconvenience to obtain accurate data, and commercial band products are difficult to collect accurate data, and cannot take into account the motive, cause, and psychological effect of behavior. the current situation. In this paper, radar technology for life pattern recognition is a technology that measures the distance, speed, and angle with an object by transmitting a waveform designed to detect nearby people or objects in daily life and processing the reflected received signal. It was designed to supplement issues such as privacy protection in the existing image-based service by applying it. For the implementation of the proposed system, based on TI IWR1642 chip, RF chipset control for 60GHz band millimeter wave FMCW transmission/reception, module development for distance/speed/angle detection, and technology including signal processing software were implemented. It is expected that analysis of individual life patterns will be possible by calculating self-management and behavior sequences by extracting personalized life patterns through quantitative analysis of life patterns as meta-analysis of living information in security and safe guards application.
