Purpose: This paper explores diverse issues related to the problem of women's unpaid domestic care work, and as a factor of gender inequality in their professional practice. Research Design: This article concentrated only on the analysis of secondary data available on the topic along with observation of facts in Kazakhstan based on diverse sources. In current conditions, the problem of women's unpaid domestic care work, and consequently, the lack of enough time and energy for professional employment. Distinguish domestic work vs. job/career/occupation, self-fulfillment, education, and leisure has a significant impact on women's life satisfaction. Data, and Methodology: This article focuses only on secondary data available in different sources from which the researchers procures comprehensive data and information. Results and conclusion: A family policy that aims to promote combining maternity, and domestic work with paid employment is an effective way to increase the proportion of working mothers/women. It is crucial to not only proportionally distribute the household responsibilities in the family but also to form an effective mechanism of state support for women through the development of the social services sector, as well as the adoption of a system-wide approach to gender equality.

Purpose Due to COVID19, the over-the-top media service (OTT) market is growing faster than expected at an annual average of 26.4%. In Korea, WAVVE, which integrated SKT's Oksusu and POOQ in September 2019, outperformed Netflix in the number of users immediately after its launch, but the number of users gradually decreased. Research on OTT investigated the spread of new media due to changes in regulations or policy, mostly in broadcasting media. On the other hand, OTT research in information systems began after the success of Netflix. It investigated consumers' satisfaction with information technology using the Information Technology Acceptance Model (TAM). This study investigates changes in consumer perceptions in the OTT market, which has grown after the Netflix's entry into Korea, the emergence of WAVVE and new OTT service providers, and the spread of COVID19. Design/methodology/approach This study selects contents, fees, service quality, and additional services as factors to evaluate consumer perception using AHP. Findings According to the 101 respondents, the content was the most important factor, followed by service quality, fees, and additional services. Contrary to previous findings that price is the determining factor in service adoption, this study reveals that consumers are willing to pay a reasonable amount for rich content and excellent service quality. Future research will use demographic analysis to reveal differences in consumer's perceptions of service selection.

First, generally the more business employ the financial and non financial outcome analysis for evaluation process, the higher the success rate of new product development becomes in the domestic restaurant market. Second, the study shows that the financial outcome tends to be considered more than non financial outcome on deciding success of the new product development. Third, it is indicated that although detailed plans have a large impact on the outcome of new product development, communication between departments within a company is not a considerably important factor for deciding success of the new product. Fourth, 'market environment' has significant influence on deciding adoption level of financial and non financial outcome analysis, organizational resources and culture.

Diode rectifier has been widely used as he preregulator of inverter arc welding machine(IAW). As it is linked to power utility a disorder of other instruments can be burst out. The adoption of voltage source PWM converters can be considered and which must catch the compromise of between performance and cost. So in this paper voltage source PWM converters which have single (i.e. PWM converter) control switch respectively are analyzed and evaluated through digital simulation and experiment. In addition the improved input characteristics of IAW are shown and compare to those of conventional one.

This paper presents a new design method of truss bridges using advanced analysis. In this approach, separate member capacity checks encompassed by the specification equations are not required because the stability of separate members and the structure as a whole can be treated rigorously for the determination of the maximum strength of the structures. The method is developed and refined by modifications to the conventional elastic-plastic hinge method. Verification studies are carried out by comparing with the plastic-zone solutions. The load-deflection behavior of the truss shows a good agreement between the plastic-zone analysis. A case study is provided for a truss bridge. Member sizes determined by the proposed method are compared with those determined by the conventional method. It is concluded that the proposed method is suitable for adoption in practice.

With the adoption of welded joints rather than bolted joints, we investigate the fatigue strength and the fatigue crack initiation of U-type trough rib and welded specimen with misalignment in a steel deck plate. The stress concentration factor of welded specimens with a misalignment is also verified by a finite element method. The main conclusions obtained from this study are as follows Experimental results of full-scaled U-type trough rib models have indicated that fatigue life depends on misalignments of welded joints in steel deck plate ; The more misalignments are, the less the fatigue life is. It has also shown that fatigue crack propagates from the welded root to the bead surface. We have also obtained the same results from both the fatigue test of welded specimens with a misalignment and the stress analysis of a finite element method.

The adoption of expert systems mainly as operator supporting systems is becoming increasingly popular as the control algorithms of system become more and more sophisticated and complicated. The verification phase of knowledge base is an important part for developing reliable expert systems, especially in nuclear industry. Although several strategies or tools have been developed to perform potential error checking, they often neglect the reliability of verification methods. Because a Petri net provides a uniform mathematical formalization of knowledge base, it has been employed for knowledge base verification. In this work, we devise and suggest an automated tool, called COKEP(Checker Of Knowledge base using Extended Petri net), for detecting incorrectness, inconsistency, and incompletensess in a knowledge base. The scope of the verification problem is expanded to chained errors, unlike previous studies that assume error incidence to be limited to rule pairs only. In addition, we consider certainty factor in checking, because most of knowledge bases have certainty factors.

An inverter-driven induction motor is used as the traction motor for a high speed drive system that required safety, reliabillity, performance, compact size owing to the space and weight alloted for attaching to train, etc. particularly it is possible to happen the saturation effects of flux density at constant voltage-frequency region and then increase very higher than the at lowed capacity of no-load current and temperature in any case. therefore the optimum design of core, optimum voltage-frequency ratio, adoption of high grade magnetic core have been developed and researched for preventing these problems. this paper show the saturation effects of traction rotor by measuring the induced voltage of search coil at stator teeth and presents optimum voltage-frequency ratio as well as optimum core design through the comparison with efficiency, power factor, load current and no-load current for korea high speed train.

The analytic test results are as follows. This thesis categorized into independent variables, multiple factors, such as asset attributes, cost reduction expectation, corporate IT competence, service qualities, system adequacy, information security, easy system management, uncertain IT, supplier capacity, intra-industry competition. And, this research thesis categorized into moderators, the factor, such as the adequacy between suppliers and customers industries. And, this categorized into dependent variables, multiple factors, such as the effects of ASP introduction. But, it was analyzed that only cost reduction expectation out of independent variables had not positive effects on the effects of ASP introduction. And, it was confirmed that the higher communications between suppliers and customers' industries, and the higher fulfillment of contracts, suppliers' service qualities, and suppliers' cooperation with customers had the adjusting effects on factors of ASP-based introduction.
