Purpose: This study aimed to identify the influence of consecutive night-shift work and working time on insomnia among hospital nurses. Methods: A descriptive correlational research designutilizing secondary data analysis was adopted. Data on consecutive night-shift work, working time, and insomnia were collected from 64 hospital nurses using a Fitbit activity tracker and questionnaires, and analyzed using hierarchical logistic regression. Results: Consecutive night-shift work for more than three days had a significant influence on insomnia among hospital nurses. Weekly working hours also accounted significantly for the variance in insomnia, exceeding the influence of consecutive night-shift work. Conclusion: Development and implementation of proper schedules to control consecutive night-shift work and working time is important to alleviate insomnia among hospital nurses.

Four monkeys (Macaca mulatta) were allowed to press a lever in their cages in order to earn access to one gram pieces of Panax ginseng root. Self-administration performance on an operant schedule (mult FR20 F11) was characterized by frequent pauses and increased intertrial interval responding. When given 23 hour unlimited access to ginseng root, as well as to food and water, all animals titrated their daily intake to approximately 1.5 g/kg. Gross behavioral changes included increases in vocalization, activity, stereotyped movements, and weight loss. These patterns of behavior are typical of those seen when monkeys self-administer psychomotor stimulants. Further studies on ginseng's reward value can be conducted using this animal model.

Astronomical outreach activities for the general public who are unfamiliar to astronomy is a challenging task. It requires creative thinking to solve the problem. The amateur astronomical clubs in a number of cities in Indonesia routinely schedule observations at public parks. The interaction between these clubs and formal education institutions is established by face to face interaction and assisted by social media. The physics teachers who took astronomy courses in university are potential resources to enlarge the outreach scope by creating astronomical clubs as an extracurricular activity. Recent progressive trends in astronomy dissemination for the disabled are also a great opportunity to assist the disabled in experiencing hands-on activities based on formal and informal education.

Korea Aerospace Research Institute has developed an earth observation satellite whose primary mission objective is to provide high resolution electro optical earth images for Geographical Information Systems (GIS) establishment and the applications for environmental, agriculture and ocean monitoring. It was successfully launched into its mission orbit by using a commercial launch vehicle on 18th of May, 2012. This paper describes a series of launch activity at the launch site including its transportation to the launch site. Before conducting the launch site operation, satellite operation plane was prepared. Combining the satellite operation plan and launch vehicle activities, an integrated launch site operation plan and schedule have been drawn up. After arrival of the spacecraft at the launch site, post-ship check out has been conducted. And then it was fuel loaded and integrated with launch vehicle hardware. After completion of final electrical check out, count down procedure was executed. on 18th of May, it was launched into the space and was separated from the launch vehicle as planned. About 3 months of early operation and calibration/validation, now the satellite is conducting its normal mission.

The purpose of the study is to propose architectural design standards of the Multi-purpose Auditorium planning in educational facilities. The success of the design is measured by how well variable elements are applied to parts of Multi-purpose Auditorium and designed and equipped so that all groups-amateurs, professionals, youth, and adult alike-may use it effectively. The use of this facility will extend over a wide range, including concerts, plays, motion pictures, forums, and other forms of presentation. The wall, stage, roof, windows, and furnitures are important parts of Multi-purpose Auditorium and variable elements can applied to these parts. To successfully application of variable elements, it is necessary that these elements are considered in planning phase including time schedule planning. Various elements are permit a more informal and flexible arrangement and extensive learning activity.

The requirement verification is the integral part of the weapon system R&D to reduce cost and schedule. And, a systems engineering is an interdisciplinary engineering management process that evolves and verifies an integrated, life-cycle balanced set of system solutions that satisfy customer needs. Therefore, this study analyzes the national defense need and acquisition management process, investigates the systems engineering verification activity. Through the requirement verification example in terms of technical evaluation this study presented the requirement verification approach in the weapon system R&D.

In this study, a learning environment based on STEAM theory was proposed to support and improve learners' activities and achievements for convergent design education. The learning environment design influence STEAM education with intentional design and schedule coordination, schools can create informal environments that are crucial to STEAM education. The physical surroundings of the learning space should be applied to teaching methods and learning activity, especially for STEAM-based education, physical space conditions should support the learner's design thinking and process. Furthermore, STEAM-based education environment should support a vast array of experiences that allow students to learn the context around ideas and skills. For spaces for learning environment based on STEAM, common design principles should be considered such as technology integration, safety and security, transparency, multipurpose space, and outdoor learning. Therefore, the learning environment based on STEAM needs flexible and mobile, connected, integrated, organized, flipped, and team-focused surroundings to support the learners understand, participate, cooperate, and accomplish the design process.

TSP(Team Software Process)의 계획 단계에서는 계획된 프로젝트 일정에 맞춘 업무를 팀 리더 또는 계획관리자(plan manager)가 각 팀원에 할당하고, 업무수행 시에는 각 팀원이 할당된 업무를 적시에 수행하는지를 추적하여 일정지연을 방지해야 한다. 하지만 업무 할당에 있어 팀원의 능력, 일정 및 업무의 논리적인 순서가 고려되어야 하고, 업무 수행 시에도 수시로 변화하는 업무 일정으로 인해 할당된 업무를 일정에 맞추지 못하는 상황이 발생하며 이는 결국 일정지연으로 이어진다. 이러한 문제를 해결하기 위해 본 논문은 TSP 가 지원하는 업무 균등 분배(workload balancing)를 적용하여 해결하고자 하였으며, 이 활동을 지원하는 도구에 대해 소개한다.

As the size of construction projects has become larger in recent years, the nature of the disaster safety factors along with the progress of construction is also becoming more complex and diversified. Accordingly, the introduction of computerized construction, new technologies, and new construction methods has resulted in a variety of risk factors in the process and operations, and many new safety construction methods are being tried. Since the construction industry has variable working environments and constantly changes working methods and components depending on the rate of progress, workers at construction sites are always exposed to risk depending on the specific circumstances of the construction industry. This study attempts to collect and analyze major accident cases generated by major accident construction projects as a result of progress in construction work, and to derive the major causes and causes for each safety management activity that affect safety accidents.
