In this paper, we analyse empirically the effects of financial characteristics on the relationship between R&D investment and market value of firms listed on Korea Exchange. The main results of this study can be summarized as follows. Firm size increase the market valuation of R&D investment because it provides economies of scale, easier access to capital market, and R&D cost spreading. Market share also positively effects the relationship between R&D investment and firm value. Alternatively, free cash flow has a negative effect on the relationship between R&D investment and firm value because firms with high free cash flow could be tempted to use the free cash flow to undertake negative NPV projects. The dependence on external finance is a handicap negatively assessed by the market when firms undertake R&D projects due to the higher information asymmetry associated with this kind of project. Labor intensity has a negative effect on the relationship between R&D investment and firm value because the abnormal profits arising from R&D investment are diluted among employees. Capital intensity also has a negative effect on the relationship between R&D investment and firm value due to the greater financial constraints faced by capital intensive firms. In conclusion, several financial characteristics(firm size and market share) positively effect the relationship between R&D investment and firm value, while others(free cash flow, dependence on external finance, labor intensity, and capital intensity) exert a negative effect. Therefore, we conclude that the effectiveness of R&D investment depends on these financial characteristics.

This study analyzes non-standard workers' attitudes and behaviors towards standard workers' strikes using the case of a joint strike held by journalists at KBS and MBC in 2012. Tracing the process since 2008 by which a conservative government has tried to control the press and regular journalists have collectively resisted against it, we put our analytical focus on two major groups of freelance broadcast professionals: independent producers and writers in current affairs. Specifically, we examine 1) how they perceived and responded to a series of regular journalists' struggle to protect journalistic value, 2) how such perception of and response to regular journalists could be developed, and 3) how (de)solidarity could form and then deepened between freelance and regular journalists in the 2012 Media Strike. Our findings show that the ways in which regular journalists had controlled freelance journalists at work affected the relationship between class-based and occupation-based rationality freelance journalists held in their minds. Independent producers, who had developed a strong class-based rationality in response to the coercive input-output control, showed cynicism about regular journalists' strike pointing out their hypocrisy and contradiction. In contrast, freelance writers accommodated and joined the strike by regular workers in the spirit of solidarity based on occupational rationality which had developed from normative, process control. Our paper ends with theoretical and practical implications.

This article seeks to explore new relationships and ethics of human and technology by analyzing a cultural imaginary produced by artificial intelligence. Drawing on theoretical reflections of the Feminist Scientific and Technological Studies which understand science and technology as the matter of care(Puig de la Bellacas, 2011), this paper focuses on the fact that artificial intelligence and robots materialize cultural imaginary such as autonomy. This autonomy, defined as the capacity to adapt to a new environment through self-learning, is accepted as a way to conceptualize an authentic human or an ideal subject. However, this article argues that artificial intelligence is mediated by and dependent on invisible human labor and complex material devices, suggesting that such autonomy is close to fiction. The recent growth of the so-called 'assistant technology' shows that it is differentially visualizing the care work of both machines and humans. Technology and its cultural imaginary hide the care work of human workers and actively visualize the one of the machine. And they make autonomy and agency ideal humanness, leaving disabled bodies and dependency as unworthy. Artificial intelligence and its cultural imaginary negate the value of disabled bodies while idealizing abled-bodies, and result in eliminating the real relationship between man and technology as mutually dependent beings. In conclusion, the author argues that the technology we need is not the one to exclude the non-typical bodies and care work of others, but the one to include them as they are. This technology responsibly empathizes marginalized beings and encourages solidarity between fragile beings. Inspired by an art performance of artist Sue Austin, the author finally comes up with and suggests 'artificial intelligence in wheelchair' as an alternative figuration for the currently dominant 'autonomous artificial intelligence'.

수자원사업에 의해 공급되는 공업용수는 대상 사업체에서 노동, 자본, 토지 등과 더불어 필수적인 투입재이다. 이러한 투입재의 안정적인 확보는 해당 산업이 부가가치를 창출하는데 매우 중요한 사안이다. 공업용수의 공급이 중단될 시 해당 산업에서의 피해액은 동일한 공급량 기준으로 봤을 때, 생활용수나 농업용수에 비해 매우 크다고 알려져 있다. 이러한 공업용수 공급의 가치를 확인하고자 본 연구는 산업단지를 대상으로 공급되는 공업용수의 한계생산가치를 생산함수 접근법을 기반으로 추정하였다. 자료의 불확실성을 고려하기 위하여 통계적 기법을 기초로 한 4가지 기준으로의 데이터 정제를 실시하여 각각에 대한 공업용수의 한계생산가치를 추정하였고, 각각의 결과로부터 최소, 최대의 범위로 제시하였다. 본 연구에서 확인한 공업용수 공급의 가치는 향후 수자원사업 시 비용배분, 용수배분, 사업의 경제적 타당성 유무 등과 관련한 의사결정의 문제에서 합리적인 기준을 제공할 수 있을 것으로 기대된다.

The purpose of this study is to analyze the actual condition of labor during the marriage by estimating the total labor-time of husband and wife and to prove the contribution of labor-time to household. The statistical life-time research data of Bureau of Statistics were used to prove the overwork of wives compared with husbands during the marriage. The result of the study can help to prove the wife's contribution of labor-time to household.

This paper investigates the effects of exchange rate and labor skill composition on Vietnam's trade balance with her twenty main trading partners. Using balanced panel data from 2000 to 2016, the authors analyze Vietnam's total trade balance and the trade balance which is disaggregated based on labor skill sophistication. Three main findings are presented. Firstly, exchange rate has a positive effect on Vietnam's trade balance, but the small value of estimated coefficient indicates that its effect is limited. Secondly, Vietnam's trade balance of the high labor-skill produced and medium-skill white collar labor-produced goods is worsened when VND (Vietnamese Dong) depreciates. Thirdly, moving up the labor skill ladder and promoting the none-price competitiveness of the high labor-skill produced and medium-skilled white collar labor-produced goods can improve Vietnam's total trade balance, while promoting the low-skill labor-produced and medium-skill blue collar-labor produced goods can no longer contribute to Vietnam's total trade balance.

직업환경의학은 유해인자의 관리와 그로 인한 건강장해의 예방이 가장 중요하다. 그러나 더욱 중요하고, 선결되어야 하는 것은 문화적인 변화이다. 내가 일하는 곳에서 노동의 가치에 대한 변화를 가져오게 하는 것에 소홀했던 것은 아닌가 다시 한 번 돌아보아야 할 시점이다.
