The article investigates the conceptual principles of transformation of industrial parks into eco-industrial ones in the conditions of sustainable development. It is substantiated that the concept of sustainable development in the transformation of industrial parks is to grow industry and jobs, modernize production and introduce innovative technologies, resource and energy efficiency, reduce greenhouse gas emissions and waste storage, social protection of local communities and create favorable infrastructure. It is determined that for the transformation of industrial parks, it is necessary to improve regulatory changes, introduce criteria for compliance of industrial parks and the importance of their consideration, ensure park management by the management company and create favorable incentives for industrial entry into industrial symbiosis. It is proved that industrial parks can be an incentive for industrial development and competitiveness of enterprises. The availability of talented human capital, attractive territories, minerals, energy and mineral resources, developed domestic market, agricultural potential, transport networks is becoming an attractive place for investment and development. Industrial parks need investment. Transformation into eco-industrial parks through the implementation of sustainable development goals opens additional opportunities for access to investment funds and contributes to the implementation of growth and prosperity strategies of the country.

The first part of the study involved calculating emission factors from electricity production. The second part of the study aimed to analyze perceptions of the concept of carbon dioxide utilization and was conducted through a questionnaire survey with participants from Almaty and Astana. The results showed that there were no significant improvements in the decrease of carbon dioxide emissions between 2017 and 2020. Almost no change occurred in the rate of carbon dioxide emission throughout the course of the four years. According to the results of the survey, a number of respondents had reservations about the feasibility of using carbon dioxide utilization as a solution to tackle climate change. They felt that this technology would only offer a temporary solution to carbon emissions, without addressing the underlying causes of the problem. Despite these concerns, the participants acknowledged that carbon dioxide utilization had certain advantages in promoting sustainability.

The purpose of this study is to examine the concept of convergence which is one of the trendy issues as a new digital paradigm of Integrative thinking in 21st century, to analyze the plastic feature and internal meaning of convergence expressed in fashion design, and to grasp the cultural symbolism through this aesthetic analysis. Because there have been considerable discussions on convergence, centering on industrial product area associated with media, I will proceed my study on the basis of them. For this, the documentary study and practical case study have been executed. This study will be helpful to find a direction of future fashion design trend. Convergence in digital stage can be defined as a phenomenon which different functions of product move towards one direction for greater efficiency, and not only as a technical integration between functions of product, but also an extension of area. Convergence can be classified by their use as (1) convergence for convenient daily life (2) convergence with intelligent scientific technology (3) convergence for entertainment on the basis of sensual experience. The plasticity of convergence designs feature as a open dynamic structure which potentiate transformation and their internal meaning can be inquired such qualities as integrative multiplicity, efficiency, mobility, intelligence. Specially convergence fashion design has protection qualify resulting from wearability on body. Ultimately convergence fashion design as a future digital paradigm can be thought as both eco-friendly design and human-centered design from positive technology-based viewpoint, because it is easy to transform according to our environment, convenient to reserve, and efficient to enhance spatial usibility.

The concept of the Mobile Harbor had been made recently as a kind of feeder vehicle to transfer a certain amount of container boxes (i.e. 250 TEU at a time) from main ocean container vessels over 5,000 TEU capacity to the container terminal on land. In a harbor a short distance apart from the land, the container loading/unloading operation has to be performed on the main deck of the Mobile Harbor using the container cranes in the state of side-by-side mooring with protection of fenders and robot arms in the gap. Even under the ocean condition of the sea state class 2 or 3, the operation has to be confirmed to be safely performed. In this situation, the floating bodies considering the multiple-body interaction effect also has to be examined whether they might behave safely or not. Especially, this study focuses on the dynamic behavior of the Mobile harbor when a container box is hanged on the crane and the impact load due to the slewing motion is imposed in a certain sea state. The motion response should be controlled within the motion level to assure the safe operation.

The function failure of present major facilities is likely to lead to failure of related systems and/or whole facilities, increasing the necessity for protection of infrastructures, main structures, and major industrial facilities. In addition, safe and efficient management for urban infrastructure (waterworks and sewerage facilities, electricity, telecommunications, roads, etc) installed in the basement or on large cities grounds at various public areas is required. Recently in response to this demand, efforts for vitalizing asset management are being made such as enacting related laws and developing asset management system in the U.S., Australia, Europe and other advanced countries with the concept for a new maintenance. In our county, identifying maintenance system problems such as aging and rapid increasing of existing infrastructures and decision-making about updating maintenance is required for systematic and organizational maintenance. In this study, by comparing and observing the LOS(Level of Service) of each countries' waterworks and risk-based LOS, we suggest the direction of future urban water infrastructure management systems for more effective management.

In order to understand the provision of social welfare in Korea, this study puts forward a method to measure and tracks the welfare mix, and applies the method to Korea. This is the goal of this study, which is in three parts. First, I critically review the concept of welfare pluralism and develop the welfare mix model, Second, I present a methodology and technique for measuring and systematically comparing the components of the welfare mix. Third, I examine the roles of five welfare providers including state, market, non-profit organization, enterprise and family in the welfare mix of Korea. This study argues that the welfare mix in Korea has some characteristics of 'residual state, expanded market, negligible voluntary sector, and protective family'. The state in Korea has played a relatively little role in the provision of social welfare, enforcing most Koreans being with a meagre social protection. Thus, most of the 'left' needs for social welfare has to be met in the private sector composed of market and enterprises. In addition, in a situation that self/mutual help through family or community is encouraged, the family has played an important role in the welfare mix. But the role of voluntary sector in the welfare mix has remained negligible. Consequently, the characteristics of the welfare mix in Korea can be best described by a welfare society rather than a welfare state.

1. This paper suggests one educational model of National Parks. The model includes main themes such as (1) concepts, (2) waste types, and (3) conservation policies of National Parks for the application at the school environmental education classes. 2. The study describes the origin of the national park system and concepts or policies for the conservation of the parks with cases of Japan, Taiwan, Canada, Australia, Swiss, Russia, and International Union for the Conservation of Nature and Natural Resources(IUCN). The main focuses of their concepts or policies are on the (1) public land, (2) conserved, (3) legally protected land, and (4) land for the education of the loving their country. 3. This research classifies wastes of parks as point, linear, areal, and cubic types, and explains wasting actions on each types, focused mainly on the mountainous national parks. 4. The suggested policies for the conserving national parks, in this paper, are (1) core-zoning policy, and (2) management policy within the core zone. 5. Some principles are suggested for the more effective realization of the policies: (1) enforcement, (2) abandonment,(3) restoration, (4) enlargement, (5) limitation, (6) incorporation, (7) monitoring, and (8) education. 6. Finally, the educational values of this model may be derived from concepts of (1) loving national land, (2) conservation of nature, (3) public responsibility for protection, and (4) education materials. Those concepts form the foundation of models for (1) civic education, (2) education of country, and (3) inquiry training.

Fire protection is one of important issues to ensure safety and reduce risks of nuclear power plants (NPPs). While robust programs to shut down commercial reactors in any fires have been successfully maintained, the concept and associated regulatory requirements are constantly changing or strengthening by lessons learned from operating experiences and information all over the world. As part of this context, it is necessary not only to establish specific fire hazard assessment methods reflecting the characteristics of research reactors and educational reactors but also to make decisions based on advancement encompassing numerical analyses and experiments. The objectives of this study are to address fire simulation in the control room of an educational reactor and to discuss integrity of digital console in charge of main operation as well as analysis results through comparison. Three electrical fire scenarios were postulated and twenty-four thermal analyses were carried out taking into account two turbulence models, two cable materials and two ventilation conditions. Twelve supplementary thermal analyses and six subsequent structural analyses were also conducted for further examination on the temperature and heat flux of cable and von Mises stress of digital console, respectively. As consequences, effects of each parameter were quantified in detail and future applicability was briefly discussed. On the whole, higher profiles were obtained when Deardorff turbulence model was employed or polyvinyl chloride material and larger ventilation condition were considered. All the maximum values considered in this study met the allowable criteria so that safety action seems available by sustained integrity of the cable linked to digital console within operators' reaction time of 300 s.

Purpose: There are already hundreds of millions of users of the Metaverse platform, and within a few years, it is expected to develop into a stage for new economic activities with huge industrial ripple effects due to the size of users. The purpose of this study is to derive considerations for the development of metaverse ethical guidelines. Research design, data, and methodology: The concept of the metaverse was examined through various opinions of industry and experts on the metaverse, and literature related to metaverse ethics was analyzed in the Korean journal database. Results: Six issues were identified through the existing research. (1) Establishing a unified definition of metaverse (2) Necessity of establishing ethical principles considering the operator (3) Personal information protection and privacy (4) Expression in a virtual environment (5) Copyright and intellectual property rights of creations (6) Virtual economy and fairness of trade. Conclusions: Metaverse ethics will be developed and implemented in a form and method different from the real world, but basically, continuous discussions on ethical rationality are needed in the process. In addition, since the ethical judgment in the metaverse environment accompanies cultural differences and epochal changes, it is necessary to focus on metaverse ethics cases.
