Construction system modeling can enhance work performance by following the behaviors of a system. System behaviors may originate from physical aspects of a system, namely operation level variables, or from non-physical aspects of a system known as context level variables. However, construction system modelers usually focus on only one type of system variable (i.e., operation level or context level) which can lead to less accurate results. Hybrid modeling with System Dynamics (SD) and Discrete Event Simulation (DES) is one of the approaches that has been utilized to address this issue. In this research, an SD-DES hybrid model of a steel fabrication shop is developed, and the benefits of capturing context level variables together with operation level variables in the model are discussed.

The article substantiates the need and shows the features of introducing SMART management into the system of public management of regional development in the context of strengthening the national security of Ukraine. Disclosed are such provisions as: goal-setting; state mission; state mission in Ukraine; goals of the Ukrainian state; strategic management priorities in Ukraine. Differences between the purpose of the organization and the purpose of the state are determined. The characteristic of the goal at the state level is given. The management standards in SMART management are characterized. The issues of the exhaustibility of existing SMART criteria are reviewed and it is proposed to supplement them with two such as: inspiration (inspiration) and ity (ethics). Two main principles are defined (evaluated (assessment), reviewed (review)), which must be observed when introducing SMART management into the system of public management of regional development in the context of strengthening the national security of Ukraine.

The main purpose of the study is to determine the main aspects of information support for anti-crisis management in the context of ensuring national security. In modern conditions, under the influence of COVID-19, it becomes important to develop a modern paradigm for the transformation of anti-crisis management, based on the determination of the laws of state development on the basis of the imperative of national interests and territorial integrity. These are, firstly, the patterns of development of the state system of public administration, secondly, the patterns of development of a complex of state interests, and thirdly, patterns of development of the modern model of the country's territorial integrity. As a result of the study, the key aspects of the anti-crisis management system were identified in the context of ensuring the security of national interests.

This research applies Blattberg's CE (customer equity) model to B2B business context. Through the model we estimate customer lifetime value of a Korean semiconductor manufacturer. The results show that Blattberg model has limiting applicability to B2B business context. To overcome the limits, several suggestions were made. The main suggestion was predicting maintenance costs for different customers groups and including decision variables regarding marketing costs that would help building a differentiated CE model for the B2B business context.

This paper reviews the literature on life course as a perspective in family studies. Life course approach on family studies have been emerged since 1960. This approach, which is challenging accepted knowledge and theory, partly reflects a shift in analytic perspective from structural models to a more behavioral thrust that views as a actor in structured situations, Life course approach is a theoretical orientation for our understanding of the linkage between individual and family development in context of changing historical context. Life course approach contributes time, process, and context to receiving in sociological perspectives on family and kinship.

This paper proposes an ontology-based context-aware home healthcare platform employing environmental factors obtained from home. The proposed platform manages the health of home residents, and notifies relatives or a medical team of critical condition through context-awareness based on home ontology by using information sensed from various sensors. The ontology definition of context-awareness from the sensed information provides technically more precise decision for us. Therefore the platform can be aware of the health state of residents and environment by reasoning exactly from data gathered from various sensors and heterogeneous devices. The platform also can individually provide the customized service for users by setting priority for critical status that can be occurred in the health state of residents.

After the advent of the Ubiquitous environment, the movement for effective information management is progressing vividly. According to this situation, this paper conducts individualized context structure for individual service and also suggests 5W1H and HFC modeling which apply using priority to manage vast context data. Thus this modeling will function as a base model to embody Ubiquitous environment and offer context based service.

Predicting the preferences of users and providing the personalized services/products based on users' preferences is one of the important issues. However, the research considering users' preferences on context-aware computing is a relatively insufficient research field. Hence, this paper aims to propose a framework for providing the personalized services based on context history in context-aware computing. Based on this framework, we have implemented a prototype system to show the feasibility of the framework. Previous researches have reasoned the preferences of the user considering only the user's input, but this research provides the personalized services using the relationship between users' profile and services.

Ontology-based context models are widely used in ubiquitous computing environment because they have advantages in the acquisition of conceptual context through inferencing, context sharing, and context reusing. Among the benefits, inferencing enables context-aware applications to use conceptual contexts which cannot be acquired by sensors. However, inferencing causes processing delay and thus becomes the major obstacle to the implementation of context-aware applications. The delay becomes longer as the amount of contexts increases. In this paper, we propose a context pre-fetching method to reduce the size of contexts to be processed in a working memory in attempt to speed up inferencing. For this, we extend the query-tree method to identify contexts relevant to the queries of a context-aware application. Maintaining the pre-fetched contexts optimal in a working memory, the processing delay of inference reduces without the loss of the benefits of ontology-based context model. We apply the proposed scheme to our ubiquitous computing middleware, Active Surroundings, and demonstrate the performance enhancement by experiments.

Recently, computing technology requires intelligent system structures for context-awareness in ubiquitous computing environment. An intelligent system for context-awareness is based on agents, and need sensor information to recognize users and frames to support service. Therefore, this paper proposes the structure of 3-tier context-awareness processing server/client that can connect dynamically with each sensor and service, and support various context stably The structure of a proposal system is composed of a client class that recognizes uses' context information, a server class that processes realized context information by an application processing agent, and a management server that manages these two classes. Also, in this structure users information is composed of dynamic profile to support exquisite service.
