Due to the rapid change in society and technology, educators are paying more attention to the use of Information Technology(IT). This paper attempts to analyze the current status of the use of IT in elementary schools, focusing on two issues. First, the present status of the infrastructure for the use of IT is analyzed. Concerning the issue, this paper examines the national plan promoted by the Ministry of Education and school curriculum on computer education. Second, the current situation and hindering factors in the school use of IT are analyzed. Concerning this second issue, the results of a, survey which was conducted in December, 1997 are reported.

건설산업의 지속적 성장과 국제적인 기술경쟁력 제고를 위해서는 건설기술 연구개발이 필수적이다. 그러나 우리나라의 건설분야 연구개발 투자는 타 산업에 비해 저조한 실정이며, 정부차원의 연구개발 투자도 외국에 비해 낮은 수준이다. 본 연구에서는 건설기술 연구개발의 투자 현황을 고찰해 보고, 연구개발의 성과를 신기술 및 특허와 관련하여 분석하였다. 그리고 신기술지정제도의 현황과 개선점을 살펴보았다. 이러한 현황 분석을 바탕으로 건설기술 연구개발의 개선 방향을 제시하였다.

The high degree of viscosity and the non-Newtonian fluid dynamics characterizes the process inside a glass furnace. Because the temperature is fluctuating in very short time-intervals, it is hard to determine that the status of its fluctuation is stable or unstable. Usually Shewhart-chart is used to determine the control status. However because of the characteristics of the temperature fluctuations in the glass furnace it does not directly serve the purpose here. Therefore we suggest using ARIMA to diagnose control status and confirm that the method using ARIMA can be a better tool than Shewhart-chart.

The sheet metal forming process is one of the most important manufacturing processes in the modern industry. From the view point of mechanics involved, it is very difficult to predict whether a newly designed sheet metal part can be formed without defects such as fracture, wrinkling and surface unevenness, etc. In order to reduce the effort taken in the trial-and-error process and to control the process effectively, a systematic method for process modeling is to required. The aim of sheet forming simulation through the process modeling is to reduce the lead time for die disign and manufacture by process modeling is to reduce the lead time for die design and manufacture by means of investigating the deformation mechanics and the mutual interaction between the process parameters. In this paper, the necessity, the present status, and the future technology about CAE of sheet forming simulation have been discussed.

In the highway engineering, the performance, quantity and status of machines available for the project have direct impact on the project time. For instance, the status of machines, such as working or in trouble, have great influence on the activity execution. Therefore, while scheduling the project, the project manager always increases the spare machines or prolong the activity time to avoid delaying the project time when some of the machines are in trouble in construction site. However, how many are the spare machines and how long are the prolonged activity time, which are estimated subjectively by the manager. This subjective estimation has been criticized for systematically overestimating or underestimating quantity of the machines and the activity time. In the paper, we propose and prototype a model to simulate the status of the machines in construction site, and then to evaluate the schedule feasibility considering the performance, quantity and statues of the machines involved.

Now a days, Lots of research about 4th industrial revolution are progressing. Attempt of technologies on construction engineering field, such as construction management by drone, building equipments based on the IoT technology and etc., are continuously tried by government and private enterprises. Meanwhile, the application of advanced technologies on the military facilities should be reviewed cautiously, because of the national defense environment such as military security. Therefore, this study aim to understanding of present status of military facilities for introduction of 4th industrial revolution technology. To achieve the aim of the study, question investigation targeting working groups for military facility management is conducted.

This study examines the acceptance factors, barriers, benefits, and strategies for resolving Information and Communication Technology (ICT) adoption and usage problems based on the different demographic characteristics of SMEs. The demographic characteristics investigated are gender, educational qualifications, age, managerial status, and years of business experience. To the best of our knowledge, this paper is the first to examine a more comprehensive demographic characteristics in the context of ICT adoption. A survey using self-administered questionnaires was conducted to retrieve information from SME owners/managers in Pekalongan, the local city of Indonesia. The items in the questionnaire were discussed with various experts in the field and a pilot study was conducted prior to the distribution of the research instrument. The study made some interesting findings. No significant differences were found in the SMEs' adoption factors between the demographics of gender groups and educational qualifications. However, significant disparities were found to exist among the age compositions, managerial status, and years in business. Additionally, younger managers/owners of SMEs find it easier to understand the background factors of ICT adoption. Lastly, older managers/owners are more likely to stick to the organizational status quo, be less able to learn new technology, and more likely to avoid risky decisions.

본 연구는 노인의 우울, 영양상태 및 인지기능이 삶의 만족도에 미치는 영향을 파악하여 변수들 간의 관계와 효과를 규명하는 위해 이루어졌다. 자료는 한국보건사회연구원에서 시행한 2017년도 노인실태조사 자료를 사용하여 2차 자료분석을 실시하였다. 65세 이상의 노인 9089명을 대상으로 경로모형을 만들고 상관분석 및 경로분석을 통해 가설을 검증하였다. 그 결과, 우울, 영양상태, 인지기능 및 삶의 만족도는 모두 유의한 상관관계를 보였다. 영양상태에 영향을 주는 요소로서 우울(.46, p=.007)의 효과 크기가 유의하였으며 인지기능에 대해서도 우울(-.27, p=.014)의 효과 크기가 유의하였다. 영양상태(.08, p=.009)와 인지기능(-.03, p=.010)은 모두 삶의 만족도에 유의한 효과를 보였는데, 우울(.50, p=.012)은 영양상태와 인지기능을 매개로 하여 삶의 만족도에 영향을 주었다. 따라서 노인의 삶의 만족도를 증진시키기 위해서는 우울에 대한 중재 뿐 아니라 영양상태와 인지기능에 대한 간호 중재가 필요하다.

Objectives: To analyze the relationships of socioeconomic status(SES) to health status and health behaviors in the elderly. Methods: Data were obtained from self-administered questionnaire of 4,587 persons, older than 65 years, living in a community. We measured the sociodemographic characteristics, socioeconomic status, health status (subjective health status, acute disease, admission experience, dental state, chronic disease etc.), activities of daily living (ADL), instrumental activities of daily living (IADL), and mini-mental state examination-Korean (MMSEK). Binary and multinominal logistic regression analyses were employed to analyze factors affecting on the socioeconomic status of the elderly. Results: With regard to the SES and health status, those with a low SES had poorer subjective health states and lower satisfaction about their physical health. Also, acute disease experiences, admission rates and tooth deciduation rates were higher in those of low SES. In the view of physical and cognitive functions, the ADL, IADL and MMSE-K scores were also lower in those of low SES. However, with regard to health behaviors, lower smoking and alcohol drinking rates were found in the low SES group, and a similar trend was shown with regular physical exercise, eating breakfast, and regular physical health check-up. From these findings, we surmise that those with low SES have a poorer health condition and less money to spend on health, therefore, they can not smoke or drink alcohol, exercise and or have a physical health check-up. Conclusion: This study suggests that socioeconomic status plays an important role in health behaviors and status of the elderly. Low socioeconomic status bring about unhealthy behavior and poor health status in the elderly. Therefore, more specific target oriented(esp. low SES persons) health promotion activities for the elderly are very important to improve not only their health status, but their health inequity also.
