Various risk factors affect construction projects. Due to the uncertainties created by risk factors, actual activity durations frequently deviate from the estimated durations in either favorable or adverse direction. For this reason, evaluation of schedule uncertainty is required to make decisions accurately when managing construction projects. In this regard, this paper presents a new computer simulation model - the Repetitive Schedule Risk Analysis Model (RSRAM) - to evaluate unit-based repetitive building project schedules under uncertainty when activity durations and risk factors are correlated. The proposed model utilizes Monte Carlo Simulation and a Critical Path Method based repetitive scheduling procedure. This new procedure concurrently provides the utilization of resources without interruption and the maintenance of network logic through successive units. Furthermore, it enables assigning variable production rates to the activities from one unit to another and any kind of relationship type with or without lag time. Details of the model are described and an example application is presented. The findings show that the model produces realistic results regarding the extent of uncertainty inherent in the schedule.

Besieged by needs for upgrading the current Internet, social pressures, and regulatory concerns, a network operator may be left with few options to Improve his services. Yet he can still consider a transition prioritizing network services. In this paper, we describe a transition from a non-priority system to a prioritized one, using non-preemptive M/G/1 model. After reviewing the constraints and theoretical results from past research, we describe steps making the transition Pareto-improving, which boils down to a multi-goal search for a Pareto-improving state. We use a genetic algorithm that captures actual transition costs along with incentive-compatible and Pareto-Improving constraints. Simulation results demonstrate that the initial post-transition solutions are typically Pareto-improving. for non Pareto-improving solutions, the heuristic quickly generates Pareto-improving and incentive-compatible solutions.

Since 2015, the Health Insurance Review and Assessment Service (HIRA) has performed annual qualitative assessments of asthma management provided by all medical institutions that care for asthma patients in Korea. According to the third report of qualitative assessment of asthma management in 2017, the assessment appears to have contributed to improving the quality of asthma care provided by medical institutions, especially primary clinics. However, there is still a gap between the ideal goals of asthma management and actual health care policies/regulations in real clinical settings, which leads to the state of standstill with respect to the quality of asthma management despite considerable efforts such as the qualitative assessment of asthma management by national agencies such as the HIRA. At this point, a harmonized approach is needed to raise the level of asthma management among several components including medical policies, efforts of academic associations such as education and distribution of the guideline for management, and reliable financial support by the government.

Purpose - Focusing on the FGI research method, the current status and issues of barrier-free tourism in Gangwon State were identified, and specific activation plans were derived Design/methodology/approach - This study conducted in-depth interviews with 20 experts related to the tourism industry. The issues, current status, and activation plan of barrier-free tourism in Gangwon State recognized by experts in tourism policy, tourism administration, tourism management, and tourism service industry were derived. Findings - First, the tendency of businesses to be promoted based on the non-disabled by not recognizing the weak as the main tourism demand group, second, confusion caused by the unification of terms related to barrier-free tourism, third, lack of finding tourism constraints subdivided according to the type and degree of disability, fourth, tourism information and evaluation indicators provided by prioritizing the convenience of suppliers rather than consumers, and fifth, the nature of the project focused on improving access to physical infrastructure. Subsequently, the results of the analysis of the plan to revitalize the barrier-free tourism industry in Gangwon State were as follows. First, education and programs to improve disability awareness appropriate to local conditions were activated, second, related information was unified and project sustainability was improved by creating a control tower for the barrier-free tourism industry at the provincial level, third, to overcome the employment crisis based on finding locally tailored jobs related to tourism care professionals, and fourth, to continuously secure quantitative and qualitative data and establish utilization plans. Research implications or Originality - First, it presents theoretical implications for related fields by providing issues and activation measures related to barrier-free tourism from the perspective of experts who are still lacking in research in academia. The practical implications are that based on the opinions of experts working in the tourism field, more specific issues of the barrier-free tourism industry in the province were presented, and policy and practical solutions were presented accordingly, suggesting realistic alternatives that can be carried out in the actual field.

This study was conducted to propose the improvements by analyzing the actual state of Education Information Disclosure related to the school libraries of elementary and middle schools and by grasping its problems. In order to do that, we examined the Education Information Disclosure standards in school libraries in Korea. The actual state of information disclosure on 13 items related to school libraries was analyzed, using S High School in Seoul as a case study. In addition, in understanding the values of school libraries easily and informing them exactly through Education Information Disclosure, it was judged that the forms and guides for disclosure and the level of school introduction services were somewhat insufficient. On the basis of that, some improvements were proposed, which could help to make the operation and management of Education Information Disclosure in school libraries more efficient.

Museum Records is both a resource for the administration and for researchers. And It is necessary for the day-to-day operation of the museum's activity and it serves researchers of all kinds. This study is aimed to grasp the present condition of museum records management in a National Museum of Korea and 11 local national museums in Korea as a case study. To this end, two methods were used to collect the essential data. First, a comprehensive literature survey was conducted to investigate foreign successful museum records management system. Second, interview and questionnaire survey were conducted to collect the data of actual state of National Museum. The results show that National Museum should be a wholly responsible for the department and disposition of professional staffs and set up the comprehensive registration system, the standard of classification considering the museum's feature and the regular estimation system. And also National Museum should expand and improve the facilities according to "Archives and Records Management of Public Agencies Act".

This paper introduces a coordinated droop control for the stand-alone DC micro-grid, which is composed of photo-voltaic generator, wind power generator, engine generator, and battery storage with SOC (state of charge) management system. The operation of stand-alone DC micro-grid with the coordinated droop control was analyzed with computer simulation. Based on simulation results, a hardware simulator was built and tested to analyze the performance of proposed system. The developed simulation model and hardware simulator can be utilized to design the actual stand-alone DC micro-grid and to analyze its performance. The coordinated droop control can improve the reliability and efficiency of the stand-alone DC micro-grid.

It is not an exaggeration to say that modern chemicals take a leading place in our life, and people live with the chemicals, having a huge impact on their daily life. The chemical industry in South Korea, ranked seventh in the world, is one of the key industries that are forming greater part of Korean economy. The actual state of the chemical industries, however, is that over 14 tons of hazardous chemicals are being discharged annually and threaten people's lives with a lack of knowledge of its potential danger. In this way, not only beneficial to us, some of these substances, All chemicals, but also present a threat fundamentally our living environment to hazards to human health and the environment, accidents such chemicals, unlike accidents general understanding the scale of damage and propagation velocity has a complex very difficult risk profile, that can occur during deployment of an accident type is also very diverse. Is the actual situation of public concern against harmful chemicals management's is amplified by the chemical accident in the wake such accidents, government and corporate and reactive system and management system prior to the chemical accident the need for communication to exchange ideas with each other between residents, providing information is important. Therefore, the government departments and corporations, which manage variety of chemicals, ought to contribute toward a development of national security by rigid control over the Hazardous chemicals.

The article explores the prospects and trends for the transformation of some basic concepts of law associated with the development of artificial intelligence systems and the problems of liability for harm caused by a robot. The prospects, conditions and consequences of vesting robots with partial (quasi) or full legal personality are explored. This process should lead to a revision of the concepts of will, subjective side and legal responsibility in the direction of their greater universalization. The legally significant signs of will, legal personality, legal liability in relation to robots, artificial intelligence systems and other complex automated information systems are clarified. The author identifies the following essential factors of legal qualification of an act committed by a robot: goals, reasons for setting goals, connections between the planned result and the action taken, the actual result, the reasons for the difference between the actual result and the planned one. The article pays special attention to the preventive function of legal liability, which, when applied to robot subjects, can be expressed in the following basic procedures. 1. Accounting for legal requirements in the behavior of the robot. 2. Timely adaptation of the robot to changes in legislation and other regulatory legal acts that affect its behavior. 3. Accounting for incidents. 4. Destruction of a series of robots whose actions lead to unacceptable consequences.
