그동안 우수한 안전관리로 이름을 떨치는 건설현장은 주로 대형건설사가 시공을 하는 현장이었다. 중소현장의 경우 인력 및 재무상태가 대기업에 뒤처지다보니 안전관리에 소홀하다는 인식이 지배적이었다. 헌데 최근 이런 인식이 한낱 편견에 불과함을 여실히 보여주는 현장이 있어 큰 주목을 받고 있다. 그 주인공은 바로 중견 건설사인 티이씨건설이 시공을 하고 있는 '명지대 자연캠퍼스 산학협력관 및 제2예체능관 신축공사현장'이다. 이곳 현장은 고용노동부가 지정한 자율안전컨설팅 대상현장으로 체계적인 안전활동과 책임 있는 자율안전관리가 펼쳐지고 있다. 특히 이곳은 현장소장을 필두로 모든 현장 구성원이 적극 재해예방활동에 참여함으로써 '공생 안전'의 모범도 보이고 있다. 이곳이 이처럼 안전에 총력을 기울이는 이유는 시공 현장이 학교이기 때문이다. 즉 안전사고가 발생해 근로자는 물론 우리나라의 미래인 학생들의 몸과 마음에 해가 가는 일이 없도록 안전에 각별한 주의를 기울이고 있는 것이다. 빈틈없는 안전관리로 중견건설사의 저력과 신념을 보여주고 있는 이곳 현장을 찾아가 봤다.

최근 정보기술과 유비쿼터스기술을 바탕으로 도시를 미래화하는 유비쿼터스도시(U-City)구축이 범 국가적으로 추진되고 있다. 이에, 정부에서는 2008년 9월 25일 유비쿼터스도시의 건설 등에 관한 법률 시행령을 발표하였으며, 유비쿼터스도시서비스(U-City Service)를 크게 행정, 교통, 보건 의료 복지, 환경, 방범 방재, 시설물 관리, 교육, 문화 관광 스포츠, 물류, 근로 고용 등의 분야로 구분하였다. 이러한 유비쿼터스도시서비스를 제공하고 운영 및 관리하는 시설로 유비쿼터스도시 통합운영센터(U-City Management Center)는 다양한 유비쿼터스도시서비스를 효과적으로 연계하여 서비스에서 발생되는 다양한 도시정보를 통합, 분석하고 제공하는 유비쿼터스도시 핵심기능을 담당한다. 하지만 이러한 유비쿼터스도시 통합운영센터의 구축은 운영조직구성, 운영비용확보, 통합서비스 제공방안, 법 제도 정비 등의 해결과제를 가지고 있어 구현방안에 대한 구체적인 연구가 요구된다. 본 연구에서는 선행연구를 바탕으로 유비쿼터스도시 통합운영센터에서 기본적으로 제공되어야 할 유비쿼터스도시서비스 유형을 제시하고 정의한다.

콜센터에서 인력 스케줄링은 매우 중요하다. 모든 콜센터에서 인건비는 고정비 성격이 강하여 차지하는 비중이 매우 높아 콜센터의 이익을 좌지우지한다. 그렇기 때문에 콜센터의 적정 인력의 고용과 배치는 인건비 뿐만 아니라 콜 성공률 또한 직결되어 있어 콜센터 운영에서 중요한 사안이라고 할 수 있다. 대부분의 콜센터가 현재까지도 관리자의 경험에 의해 인력배치를 수립하는데, 이러한 방법은 과학적이지 않으며 인원수에 영향을 미치는 모든 변수들을 고려할 수 없다. 과거 수학적 모델을 수립하는 것이었다면, 지금은 모델을 학습시키고, 학습된 모델을 기반으로 미래의 고객과 인원수를 예측해야 한다. 본 논문에서는 수리제약식을 통해 다양한 변수들을 고려하고 비선형 정수 계획법과 딥러닝 기반의 예측 값을 이용하여 비선형 정수계획법을 통해 최적의 인력배치 스케줄링을 수립하였다.

Based on the knowledge spillover theory of entrepreneurship(KSTE) and resource based view(RBV), this study examines that how patent based entrepreneurship impacts on improving key performances such as financing, firm innovation, sales, product selling growth, employment. This study which is conducted with data from 353 startup firms indicates that patent based entrepreneurship has positive effects on performance of financing, innovation, product selling growth, and employment. On the other hand, there is no effect of patent-based entrepreneurship on sales performance. This statistical results were the same The results were the same when the independent variables were measured as intensity of patent based entrepreneurship which indicates the rate of patent based product or service among total number of product or service of the startup company.

The Smart Network Project is planned for achieving the Internet advanced country by adjusting the Government Future Internet Development as a national agenda. The future Internet is defined as diverse alternative technology and services that can provide optimal services for individual characteristic and situation in anywhere, anytime throughout convergence of communication, broadcasting, and computing to solve the current limitation of the Internet. This paper is to analyze the economic effects of the smart network build-up. For the economic effect analysis, we reclassified the smart network industry classification system and re-drew up 2011 Inter-industry Relations Table by using the Inter-industry Relations Table issued by the Bank of Korea and the RAS techniques. And we analyzed the economic effects that can be drawn from the investment of the smart network industry. As a result, the gross production inductive effect which appears with the economic effect of the smart network establishment project from 2011 to 2015 came out to be about 72 trillion 808.2 billion KW, added value inductive effect of 44 trillion 192.9 billion KW and the employment inductive effect of the job creation of about 412 thousands people. Afterward, it is anticipated that the smart network build-up project to contribute to the improvement of Koreans' daily life. Moreover, this research will be used as a valued basic material in the pursuit of the future network projects.

In this study, we investigate the effects of technology innovation investments and employment on credit ratings of very small start-up businesses using the data period of 2009 till 2015 test two hypotheses: asymmetric information hypothesis or competence hypothesis. We use financial and non-financial data of 51,903 observations of 12,028 small businesses from a database of a commercial bank and fixed effects panel models and two-stage instrumental variable models. We find that in the short-run small size startups show lower credit ratings than non-startups, and that both technology innovation activities and employment capability improve their credit ratings. In the long-run, technology innovation investments do not improve their credit ratings of later years while employment capability improve their credit ratings of the subsequent year. In addition, the age of startups improves their credit ratings of the current year and until the subsequent two years while employee productivity, fixed ratio and ROA positively affect their credit ratings for up to three years. However, short-term and overall debt ratios, cost of borrowings and firm-size negatively affect their credit ratings for up to three years. The results of the study on credit ratings suggest that credit rating agencies seem to consider both technology innovation activities and employment capability in the credit ratings of small start-ups as 'competence factors' rather than 'asymmetric information factors' with inefficiency and cost burdens. The results also suggest that we must find ways to reflect properly the severe asymmetric information of the early-stage start-ups, and technology innovation activities and employment capability in the credit rating formula.

This study is focused on the historical route in which reconciliation between work and family has been operating in the United States whose welfare standards are low, by using analytic narratives, from late 19th century to early 20th century. The first step saw an increase in the social advancement of unmarried women due to the increase in employment in the occupation of white-collar, as well as the increase of women in the Academy and in educational institutions. In the second step, the social advancement of married women was increased by the enforcement of the New Deal, consumption capitalism, and World War II. In the third step, the sphere of highly-educated women was expanded to a professional one through active measures aimed at gender equality, and the women's liberation movement of the 1960s took place. The United States' path model was completed in the fourth step. This study show that the most important factors have a significant influence to complete route of the American's Route were individual efforts of women (capacity building through the academic and the powerful women's movement) and the individual employment relationship in labor market. This study shows that individual efforts of women, especially in building capacity through the academic and the powerful women's movement, and the labor market, whose individual employment relationship is well-developed, have a significant influence on completing the route of the highly educated middle-class women in America.

The energy density of lithium-ion batteries (LIBs) determines the mileage of electric vehicles. For increasing the energy density of LIBs, it is necessary to develop high-capacity active materials that can store more lithium ions within constrained weight. The rapid progress made in cathode technology has realized the utilization of the near-theoretical capacity of cathode materials. In contrast, commercial LIBs have still exploited graphite as active material in anodes since the 1990s. The most promising way to increase anodes' capacity is to mix high-capacity and long-cycle-life silicon oxides (SiOx) with graphite. However, the low initial Coulombic efficiency (ICE) of SiOx limits its content below 15 wt%, impeding the capacity increase in anodes. To address this issue, various prelithiation techniques have been proposed, which can improve the ICE of high-capacity anode materials. In this review paper, we introduce the principles and expected effects of prelithiation techniques reported so far. According to the reaction mechanisms, the strategies are categorized. Mainly, we focus on the recent progress of solution-based chemical prelithiation methods with commercial viability, of which lithiation reaction occurs homogeneously at liquid-solid interfaces. We believe that developing a cost-effective and mass-scalable prelithiation process holds the key to dominating the anode market for next-generation LIBs.
