The aim of this study is theoretical and methodological justification of formation of a new policy of spatial development of Kazakhstan's economy, which is based on the principles of inclusiveness and smart specialization. Unlike previous research, the scientific significance of the obtained results consists in the conceptual justification of the basic theoretical concepts; spatial development, covering issues of concentration, specialization, and location of production. In this study, we used scientific methods: conceptual approach involves studying various concepts of spatial development on the principle of inclusive growth and smart specialization; economic analysis allows conducting a brief assessment of the economic status of regions for a certain period; structured approach involves to the formation of new policy of spatial development. Based on this research we conclude that most successful regions have formed based on principles of inclusiveness and smart specialization, which increases opportunities for well-functioning synergistic mechanism in the field of advanced technologies with subsequent access to global markets.

This paper presents an optimization of the reinforced concrete ribbed slab in terms of minimum CO₂ emissions and an economic justification of the final optimal design. The design variables are six geometry variables including the slab thickness, the ribs spacing, the rib width at the lower and toper end, the depth of the rib and the bar diameter of the reinforcement, and the seventh variable defines the concrete strength. The objective function is considered to be the minimum amount of carbon dioxide gas (CO₂) emission and at the same time, the optimal design is economical. Seven significant design constraints of American Concrete Institute's Standard were considered. A robust metaheuristic optimization method called improved dolphin echolocation and ant colony optimization (IDEACO) has been used to obtain the best possible answer. At optimal design, the three most important sources of CO₂ emissions include concrete, steel reinforcement, and formwork that the contribution of them are 63.72, 32.17, and 4.11 percent respectively. Formwork, concrete, steel reinforcement, and CO₂ are the four most important sources of cost with contributions of 67.56, 19.49, 12.44, and 0.51 percent respectively. Results obtained by IDEACO show that cost and CO₂ emissions are closely related, so the presented method is a practical solution that was able to reduce the cost and CO₂ emissions simultaneously.

The BESS has a major advantages such as load leveling, quick response emergency power (spinning reserve), frequency and voltage control, improvement of reliability, and deferred generation and transmission capacity construction. However, the economic feasibility of these systems requires justification from the customer side of meter. In this paper, we proposed the economic evaluation model of BESS which is modified and complemented the SYSPLAN model[2]. In addition, we analyzed a economic evaluation from the economic measures such as payback period, overall benefit, ROI, and ROR.

There is a general challenge offered to the field of engineering economics by the introduction of advanced technologies. A survey of the existing literature on evaluation of advanced information and manufacturing system indicate that the traditional approaches are inadequate for economic evaluation techniques used in its appraisal, difficulty in evaluating the potential benefits and criteria used to assess management performance. In this paper, an attempt has been made to overcome the above deficiencies by presenting an approach to account for the justification and selection of the Local Area Network(LAN) architectures. This is based on the Analytic Hierarchy Process(AHP) and is capable of taking into account many intangible factors as well. The usefulness of the proposed approach is demonstrated through a case situation and sensitivity analysis. Finally, some research directions for future work are identified.

RFID 확산이 어려운 이유 중 하나는 구체적 경제성 분석 방법의 부재라 할 수 있다. 기존 문헌 분석과 파급 효과가 큰 택배산업 사례를 통해 RFID 도입에 따른 비용/혜택 분석을 포함한 경제성 분석 방법을 제시하였다. RFID 적용 효과의 기대 수준을 낙관적, 보수적, 비관적으로 정의하여 분석하고, 태그 단가 등에 따른 민감도 분석을 통해 RFID 비용과 RFID 기술 기대 수준에 따른 불확실성을 반영하였다. 본 연구의 결과는 RFID 도입을 위한 의사결정에 기여할 수 있을 것으로 예상된다.

본 연구는 가정폭력의 사회적 중요성이 부각되는 가운데 가정폭력 정당화에 영향을 미치는 개인수준과 국가수준의 요인을 진단하였다. 개인수준의 변수로는 경제적 역할에서의 여성에 대한 편견과 사회적 역할에서의 여성에 대한 편견을 사용하였으며, 국가수준의 변수로는 성불평등에 영향을 주는 여성취업율과 민주주의지수를 고려하였다. 분석에 포함된 국가는 총 36개 국으로 개인수준에서는 세계가치관조사 자료를 사용하였으며 국가수준에서는 국제부흥개발은행의 여성취업률 자료와 경제정보연구소에서 발행한 민주주의지수 등을 활용하였다. 분석결과 개인수준의 변수인 경제적 역할에서의 여성에 대한 편견과 사회적 역할에서의 여성에 대한 편견 모두 가정폭력 정당화에 유의미한 영향을 미치는 것으로 나타났으며, 국가수준의 변수인 여성취업률과 민주주의지수 또한 가정폭력 정당화에 유의미한 효과를 보이는 것을 알 수 있었다. 개인수준의 왜곡된 성역할 인식과 국가수준의 성불평등이 가정폭력 정당화를 초래할 수 있다는 이러한 결과는 성역할에 대한 긍정적인 사회문화 조성과 국가수준에서의 성 평등에 대한 노력의 중요성을 보여주며 정책적인 시사점을 제시하였다.

This research is devoted to the development of methods general and standard methodological approaches and approbation those for the evaluation of economic potential and level of concentration of the regions of Kazakhstan. This paper presents the results of development of the authors on the selection and justification of the methodological approaches for quantitative evaluation of the economic potential (the degree of territorial differentiation of the profile) and concentration of regions. In this study, we used scientific methods: method of analysis the main trends of economic development, and method of evaluation of concentration of the region. Based on the analysis of foreign techniques developed and tested methodical approaches to the assessment of the economic potential (index and coefficient methods). Proposed methodological approaches to the assessment profile of the territory and developed a system of indicators, which includes an aggregated index of spatial concentration, which accurately reflects the concentration of production in the region. This study shows the results of the analysis of the potential regional disparities and trends of economic development of Kazakhstan. By using, the proposed methodology shows the possibility of their use; we calculated the indicators of integrated assessment of the economic potential and indicators of spatial concentration.

This paper analyzes the role of absorptive capacity in R&D spillovers through strategic R&D investments in a game-theoretic framework. In the model, a firm's effective R&D is composed of idiosyncratic R&D, which produces its own innovations, and identical R&D, which improves absorptive capacity. The model shows that in the presence of absorptive capacity firms have a tendency to underinvest (overinvest) in idiosyncratic (identical) R&D relative to the social optimum. As the spillover becomes larger, firms decrease their own R&D while they become more inclined towards strategic exploitation of rivals' efforts. Since the former effect overpowers the latter, the total amount of R&D decreases as the spillover increases. This is socially undesirable, providing a potential justification for a governmental subsidy for idiosyncratic R&D and a tax on identical R&D. The findings may have important implications for newly industrialized or emerging countries that consider a redirection of national R&D policy and intellectual property rights (IPR) regime.

This study is concerned with the economic analysis of implementing a material handling system using automated guided vehicle(AGV)s in order to improve the productivity of the production process of chinawares. Analytic hierarchy process(AHP) method for selecting the facilities of material handling systems is presented. Subsequently, as an example, a chinaware production line is analyzed for the economic analysis. The result shows that seven manpowers can be reduced. However the introduction of the new material handling system is turn out to be undesirable due to high initial cost of AGV system, Nevertheless, in the long term, automatic material handling system such as AGV system are expected to play major roles in the modern manufacturing area.

The Battery Energy Storage System(BESS) has lots of advantages such as load levelling, quick response emergency power(spinning reserve), frequency and voltage control, improvement of reliability, and deferred generation and transmission construction. The economic feasibility requires justification from the customer side of meter to promoting the dissemination of BESS nationally. In this paper, we proposed the economic assessment model of customer owned Battery Energy Storage System(BESS) which is complemented and improved the existing model. The proposed model is applied to the typical customer type(light-industrial commercial, and residential) which are taken from the statistical analysis on the load profile survey of Korea Electric Power COmpany (KEPCO). The economic assessment performed for each customer type to justifying their economic feasibility of BESS installation from the economic measures such as payback period, overall benefits, ROI, and ROR. The results of this paper are useful to the customer investment decision making and the national energy policy & strategy.
