건강마을사업과 안전거리조성사업의 혼합시행에 관한 연구

The convergence that started with the saying ‘technology and design are one’ has already been proven as the beginning of the 4th industrial revolution.In this study, the CPTED(Crime Prevention Through Environmental Design) project and the cognitive health village development project are combined to present the possibility of two projects that promote safety and health at the same time. Through the case and statistics of the two projects that are being re-implemented, we want to confirm through the survey data and to make the most of the strengths of each project to ensure that public design has a priority role in protecting the safety and health of residents. To achieve this purpose, this study went through the following case study process. First, we investigate the current CPTED project and design situation in Korea, By examining the case of Samtaegi Health Village, which is the second cognitive health village that has been implemented, It was confirmed whether the G-Health project could be fused with the CPTED project.Through this study, future projects are expected to maximize the role of public design by enabling not only CPTED crime prevention, but also the safety and health of residents in an aging society tailored to each regional characteristic.

A checklist for the evaluation of software process line approaches

A Software Process Line (SPrL) can help organisations to construct bespoke software development processes for specific project situations by reusing core assets. However, as there are diverse approaches for SPrL Engineering (SPrLE), this necessitates proper assistance to organisations in selecting the SPrL approach best suited to their needs. This paper aims to identify an evaluation checklist that can be used for evaluating SPrLs. The checklist was constructed in five stages: first, relevant aspects for managing process variability in the context of SPrLs were identified; based on these, research questions were then formed in the second stage. In the third stage, to answer the research questions, a literature review was conducted that focused on analysing 39 primary studies. In the fourth stage, the checklist was built by synthesising the literature results. In the fifth stage, the checklist was applied to two SPrL approaches as a proof of concept. The checklist includes seven main aspects, including the modelling language used, the type of the approach based on the number of artefacts produced, the language constructs provided for variability modelling, the process perspectives covered, the tool used for supporting the SPrL approach, the variability-specific features provided to support process variability throughout the SPrL lifecycle, and the empirical evaluation conducted to evaluate the approach. The checklist can be used by organisations to compare SPrLs and then select the most suitable SPrL approach; furthermore, it can be used by researchers to propose novel SPrL approaches that consider important aspects for variability management throughout the SPrL lifecycle. Although we have provided an example of the use of the checklist to compare SPrLs, an empirical evaluation of the checklist is required to get feedback from the organisations regarding the strengths and weaknesses of the checklist.

Simultaneous scheduling of multiple construction projects considering supplier selection and material transportation routing

In a construction supply chain, supply-related decisions can affect project scheduling because the project activities require essential resources to start. This study wants to show how the integration of project scheduling with supplier selection and transportation routing creates value in the entire project supply chain. Therefore, an integrated problem including the three mentioned concepts is considered in an organization managing multiple construction projects. Moreover, the following conditions are assumed in the problem to make it closer to the real situations of construction projects: (1) the quality of all projects is inspected by a single committee; (2) suppliers sell the resources with incremental discounts; (3) generalized precedence relations are considered between the project activities. In order to address the research problem, a mathematical model is proposed based on mixed-integer linear programming. The model is hard to solve because it simultaneously involves multi-project scheduling and vehicle routing. Therefore, a solution method based on the tabu search (TS) algorithm is suggested, validated with small-scale and big-scale examples. This method is used to compare the suggested model with two related models. The comparisons show that the proposed model creates a better balance between costs of different sectors in the project supply chain. Achieving this balance decreases the total cost associated with the problem and increases customer satisfaction. As a result of these findings, project managers and related researchers should pay more attention to supply chain integration in their problems.

Investigation of the support constraint effect and failure instability law of tunnels constructed using the New Austrian tunneling method

The application of a reasonable numerical calculation method is the key to accurately analyzing tunnel rock-support interactions. In this paper, we address the support constraint effect of tunnels and analyze the influence of related factors based on the confinement convergence method. Rupturable support models are developed using FLAC3D to intuitively show the numerical calculation results of tunnels. The results imply that the virtual supporting force generated by the support constraint effect should be considered in two-dimensional rock tunnel model calculations, and that the supporting force of the support should be increased by 2–3% of the maximum supporting force. Boundary effects should be considered in the three-dimensional tunnel model calculations, in which the influence range of the model boundary effect is nearly 1.5 times the tunnel span. A comparison of the field monitoring data and numerical calculations of the Baoshan tunnel project shows that the numerical results that consider the support constraint effect are in better agreement with the actual project situation. The rupturable support models can also reflect the stress and failure evolution law of supports, and provide support for the accurate evaluation of tunnel engineering stability.

The Ecological Compensation Mechanism in a Cross-Regional Water Diversion Project Using Evolutionary Game Theory: The Case of the Hanjiang River Basin, China

As a vital method to resolve conflicts between water use in upstream and downstream areas and solve the problem of transboundary water pollution, watershed ecological compensation is widely used worldwide. It is necessary to analyze the influencing factors of watershed ecological compensation from the perspective of how different governments interact with each other. However, the previous literature has paid less attention to the special situation of cross-regional water diversion projects, the changing processes of governmental behavior, and the interventions by the central government. Therefore, when taking the upstream and downstream governments and the central government in the basin of a cross-regional water diversion project as research objects, it is important to study their behavior and influencing factors to improve the ecological compensation system in the basin. This paper first analyzes the interactions among upstream, downstream, and central governments in the basin, based on evolutionary game theory. Second, the evolutionary game models before and after the interventions by the central government were developed separately, and the effects of different contexts on the dynamic evolutionary process were analyzed. Finally, taking the Hanjiang River Basin as an example, which is where the water source area of China’s South-to-North Water Diversion Middle Project is located, the opportunity cost of protecting the water environment in the upstream areas of this basin was estimated by establishing an econometric regression model using data on water quality and gross domestic product. The results show that (1) the initial probabilities of governments affect their final behaviors; (2) even without the supervision of the central government, it is still possible for upstream and downstream governments to reach the desired state spontaneously; (3) the supervision of the central government can promote upstream and downstream governments to reach a stable state faster; and (4) the current level of compensation from the central government is significantly lower than the opportunity cost of protecting the water environment for upstream governments in the Hanjiang River Basin. This paper can provide helpful insights for improving the ecological compensation system in the basin, which helps promote cooperation in water environment protection.

JUSTIFICATION FOR THE CHOICE OF MOBILE APPLICATIONS FOR CREATING AND ORGANIZING A FASHIONABLE WARDROBE

In recent years, there has been a noticeable trend in the research and development of mobile applications for working with consumers’ wardrobes. Several applications have similar functions. The applications can be found on the platforms of Google Play, App Store, and others. However, all these works are aimed primarily at meeting the needs of end-users of garment products. Thus, the main goal of the current research is to provide a reasonable selection method to choose a mobile application for the specific situation. The performed comparative analysis of mobile applications for creating a capsule wardrobe allows one to reasonably choose a mobile application for use in the learning process, as well as in the domain of the real economy besides operating by end-users themselves. In this case, in a specific project or a specific educational situation, it is advisable to form a list of additional requirements that are key to solving this problem. The formulated working hypothesis of the research on the possibility of adapting existing mobile applications to the production/training needs of the apparel industry has been confirmed by the example of several applications. The use of ready-made mobile applications that already exist in the market of mobile technologies, allows companies to offer technology that does not require any costs for its implementation; it does not require any additional equipment – almost every employee already has a smartphone. In addition, such technology does not require additional training. The same thesis applies to education: no additional equipment is needed to attract such technology. Higher education students can take advantage of automation even in classrooms that are not equipped with computers. The implementation of digital tools such as mobile applications in the educational process will increase the interest and involvement of students in the learning process. Customizing mobile applications that are already on the mobile market will create a transition between the learning process and specific project situations in the workplace. It will provide the young specialist with a digital tool that avoids mechanical errors and facilitates the decision-making process.

Economic Benefit Evaluation System of Green Building Energy Saving Building Technology Based on Entropy Weight Method

The development of the construction industry has brought great convenience to people’s lives, but the problems of resource shortages and energy consumption are becoming more and more serious. In order to solve the problem of resource shortages and energy consumption, this paper puts forward an evaluation system of technical and economic benefits of green building energy conservation based on the analytic hierarchy process and entropy weight method. In view of the correlation between building technology and economic benefits, this paper puts forward the economic benefit evaluation system of green building energy-saving technology combined with analytic hierarchy process and entropy weight methods, determines 6 first-class evaluation indexes and 20 s-class evaluation indexes, and takes the dynamic incremental investment payback period and incremental economic benefit ratio as the evaluation indexes, and finally obtains the economic benefit score and star value of green building. Combined with the actual situation of a middle school project, the incremental economic benefits of the four green technologies in energy conservation and resource utilization indicators are 44,256.75 yuan, 1,015,924.2 yuan, 255,490 yuan and 32,871.57 yuan, respectively. The total incremental economic effect and unit incremental effect of the six evaluation indicators are 1,472,113.3 yuan and 1501.99 yuan/m2 respectively. The economic effect of energy-saving and renewable resource utilization technology is the largest. The total score of the project is 0.404902 and it has three stars. Compared with traditional building technology, the application of green building technology and related facilities and equipment proposed in this paper can greatly reduce the consumption of building resources, so as to achieve the purpose of energy conservation and emissions reduction. This method combines objective evaluation with subjective evaluation, complements fair objective evaluation and expert evaluation, makes the best use of all basic information, and ensures the scientific effectiveness of the comprehensive evaluation model.

Designing a Serious Game for Scrum Learning

Scrum approach is now an important component of project management courses in universities. Experiential learning approaches as serious games seem to be more effective for Scrum learning since they have the advantage of providing students with an opportunity of encountering complex, realistic project situations. However, these educational games often lack clear specifications as to how they are to be incorporated within an experiential learning approach following a systematic instructional design. In this paper, we propose a conceptual framework that shapes serious games design, providing guidelines that allow integrating mechanisms of transfer aligned with the nature of knowledge. These transfer mechanisms rely on a “boundary perspective” with the use of boundary objects and boundary actors as a means to fostering social exchange during the game. Our framework is tested through the design of a LEGO serious game, MindScrum, to strengthen Scrum learning. We present the design principles of the game and discuss its effectiveness in the learning process.

Adapting to Environmental Changes: the Risks of Social and Technological Innovations

The initial methodological position mentioned in the article is the following statement: changes at any level contain a potential threat of damage — that is, a risk — and require developing a strategy for taking on these risks. The article expands on why scientific research is relevant, and speaks of how important it is for management practices to accumulate and generalize sociological knowledge about the social and personal determinants affecting how the population chooses its adaptation strategies in response to such changes in the institutional environment that violate their traditional way of life. The study object is the population, the subject — the main determinants that define how one adapts to the risks of environmental innovations. Adaptation in the context of this article is interpreted by the author as the process of choosing and implementing a decision pertaining to the types of actions that ensure the subject’s minimal vulnerability when dealing with the risks of a changing living environment. In order to identify the factors that influence choice of strategy for adapting to such environmental changes that may cause damage to a human being’s health and lifestyle, the projective situation method was used. Data from the 27th wave of RLMS–HSE was used as the empirical data base. The author correlates the interpretation of empirical data with the resource approach, specifically with the idea of “total life resource” (N.F. Naumova). The goal is to identify the relationship between choosing a particular strategy for adapting to the risks of environmental innovations and individual elements and indicators of total life resource. Our analysis allowed for us to propose an expanded typology of strategies for forced adaptation to the risks of environmental changes, as well as to identify a number of factors that determine the choice. Overall it can be argued that such a type of resource as one’s natural abilities seems to contribute to differentiation in the most significant way. If we look into individual factors, the following contribute to strategy differentiation: age, presence of and desire to achieve life goals, ability to adapt, emotional and psychological status, preferred method for solving problems, health, life satisfaction, gender, level of education, social status.

Most of the noise measurement result exceeds the noise quality standard and its effects up to 50 meters away from the noise source. The point which is about 5 meters away from the noise source is 63.73 dB (A) and point which is about 50 meters away from the noise source is 59.89 dB (A). Based on the results of the regression equation shows that houses within 120 meters of the project impacted by the noise that exceeds the noise quality standards for the residential area. The most complaints given by people of PerumahanTanjung Mas were feeling discomfort in daily activities (79%), and sleeping trouble (60%).

Concentrated solar power: technology, economy analysis, and policy implications in China.

Renewable energy plays a significant role in achieving energy savings and emission reduction. As a sustainable and environmental friendly renewable energy power technology, concentrated solar power (CSP) integrates power generation and energy storage to ensure the smooth operation of the power system. However, the cost of CSP is an obstacle hampering the commercialization of this emerging industry, so the paper studies the technical characteristics, economic analysis, and policy implications of CSP. This paper sorts out the relevant policies of CSP and uses the levelized cost of electricity (LCOE) model by considering financial parameters, investment parameters, operation and maintenance parameters, tax parameters, capacity parameters, etc., to analyze the economics of CSP. The model parameters are set by the actual situation of CSP projects. The economic evaluation of different technology types of parabolic trough (PT), solar tower (ST), secondary reflection ST, and linear Fresnel reflector (LFR) is carried out. The LCOE of PT project is 1.11 RMB/kWh (0.17 US$/kWh), the ST project is 0.93 RMB/kWh (0.14 US$/kWh), the secondary reflection ST project is 0.97 RMB/kWh (0.15 US$/kWh), and the LFR project is 0.92 RMB/kWh (0.14 US$/kWh). The results show that the grid parity era of CSP in China is within reach, and ST is the most potential technology type. Based on the results of economic analysis and the problems faced by CSP in China, this paper puts forward policy implications by preferential loans, tax incentives, and R&D fund support to promote the development of CSP.
