Background: Gig workers, also known as platform workers, are independent workers who are not employed by any particular company. The number of gig economy workers has rapidly increased worldwide in the past decade. There is a dearth of occupational health studies among gig economy workers. We aimed to investigate the association between exposure to violence and job stress in gig economy workers and depressive symptoms. Methods: A total of 955 individuals (521 gig workers and 434 general workers) participated in this study and variables were measured through self-report questionnaires. Depressive symptoms were evaluated by the Patient Health Questionnaire-9 when the score was greater than or equal to 10 points. The odds ratio with 95% confidence interval was calculated using multivariable logistic regression adjusted for age, sex, working hours, education level, exposure to violence and job stress. Results: 19% of gig economy workers reported depressive symptoms, while only 11% of general workers reported the depressive symptoms. In association to depressive symptoms among gig economy workers, the mainly result of odds ratios for depressive symptoms were as follows: 1.81 for workers type, 3.53 for humiliating treatment, 2.65 for sexual harassment, 3.55 for less than three meals per day, 3.69 for feeling too tired to do housework after leaving work. Conclusions: Gig economic workers are exposed to violence and job stress in the workplace more than general workers, and the proportion of workers reporting depressive symptoms is also high. These factors are associated to depressive symptoms. Furthermore, the gig workers associated between depressive symptoms and exposure to violence, job stress.

Since the profess of the reformation and opening Policy in 1978, China has been outstandingly developed its economy and increased the real scale of its economy 4 times as big as before, and is expected to rise as a superpower holding in check U.S.A even in economy as well as politics, military affairs and diplomacy in the 21st century. In this position, China has constantly tried to join WTO since 1986, as an effort to gain a status in the international society. It hsa been making various economic reformations to provoke a crustal movement in its own economy such as tariffs lowering measurement for the almost whole items, remove of restriction of import items, lowering the refunding rate of over deposit tax and annihilation of the special treatments for the foreign investment. In short, recently Chinese government is cutting down the special treatments for the foreign capital enterprises and changing the policy to the direction of gradually reinforcing the control, so it requires that our enterprises trying to advance and invest in China have to consider these carefully. Investment in China of our enterprises become serious since 1990 is focused on such labor intensive industries as textiles, sewing and shoes which lost the competitive power due to the wage increase. Particularly, Pusan economy having played the role of locomotive for Korean economy in the past developing period has been weakened in the competitiveness and not yet activated in 1990s. In terms of this, the enterprises engaged in such typical industries of Pusan as shoes, textiles and sewing have borne much fruit from the investment in China with abundant and cheap labors. However, from a few years the enterprises in Pusan invested in China due to the cheap labors and rich resources and invested in China have suffered much troubles and failures more and more resulted from the advancement without sufficient previous knowledge and information related to the investment including investment environment. Therefore, at the time of advancement in China, Korean enterprises should make their decision related to the investment, after taking these investment environment into account previously to a full extent and making an investment strategy.

본 연구는 국내외 경제변화가 인천경제 및 인천국제공항에 미치는 영향에 대한 실증적 분석을 시도하였다. OECD회원국, 인천광역시와 인천국제공항을 연구대상으로 2001년 인천국제공항 개항 이후 11년간의 경제변화를 시계열 자료를 이용하여 다중회귀분석과 경로분석을 시도하였다. 연구결과, 국내외 경제변화는 인천경제 및 인천국제공항의 성장 및 활성화에 정(+)의 영향을 보여주지 않았으며 국제경제요인은 인천경제에 직접적으로 정(+)의 영향을 보였으나 한국경제와 연관된 총 효과는 부(-)의 영향을 보였다. 따라서 인천경제는 국내외 거시경제변화요인에 능동적으로 대응해야 할 뿐 만 아니라 내발적 성장방안이 요구되며 이를 위한 방법론으로 공항도시 조성의 필요성을 제시하였다.

오늘날 금융자본의 세계화가 진전됨에 따라 금융위기의 발생가능성과 세계경제의 불확실성이 한층 더 높아지고 있다. 한국에서 IMF 금융위기는 사회 전반의 구조조정을 추동시키면서 양적, 질적 경제적 변화를 일으키고 있어 본 연구는 광주지역의 경제적 공간의 변화를 살펴보았다. 광주지역경제에 영향을 크게 미치는 산업은 서비스업과 수송장비제조업 등을 들 수 있는데 이들 산업은 IMF금융위기의 경제적 침체의 영향을 민감하게 받았고, 대신 고무 .플라스틱.기계장비.전기전각 부문의 제조업은 상대적으로 영향을 적게 받았다. 공간적으로는 서비스업의 감소로 도심지역의 상업이 쇠락하고, 첨단산업육성을 통한 위기 극복의 노력으로 인해 광산업 집적공간의 형성과 벤처기업이 입지한 창업보육센터나 벤처빌딩과 같은 미시산업공간이 나타나고 있다. 그러나 첨단산업의 지방뿌리내림은 첨단산업의 수도권 집중의 구조적, 지리적 한계를 지니고 있으며, 따라서 지역혁신체제의 구축에 대한 연구가 필요하리라 생각된다.

본 연구는 서비스경제의 발전을 이끌어갈 기본 철학을 탐구하였다. 한국고유사상이 서비스경제 철학에 부합하며, 한국고유사상의 발현을 통해 서비스문화가 확산되고 서비스경제가 활성화될 수 있음을 제시하였다. 서비스경제는 서비스라는 관계재화가 중심이 되므로, 실체성을 강조하는 서양철학보다 관계성을 강조하는 동양철학이 서비스경제 철학으로서 더 부합한다고 할 수 있다. 음양 또는 천지의 2태극 사상은 서비스경제에서 중심으로 부상된 인간의 역할을 강조하고 있지 않으므로, 인간을 중시하는 새로운 철학이 요구된다. 천지(음양)의 양극 구조 철학을 뛰어넘는 천지인 3태극 구조의 한국 고유 사상이 서비스경제시대, 제4차 산업혁명시대에는 인류사회와 경제의 발전을 견인하는 중심철학이 될 수 있다. 천지인 3재의 본성은 조화성, 수평성, 쌍방향성, 관계성 등의 서비스본질과도 부합하므로 천지인 3태극 사상은 서비스경제시대의 기본 철학이 될 수 있다. 인간이 하늘과 땅의 주관자 및 주도자로서 역할을 하는 사상이 현대 서비스경제에서 경영자와 종업원 및 소비자인 사람이 창조자로서 중심역할을 하는 구조와 부합한다. 따라서, 한국고유사상은 서비스경제를 이끌어갈 사상적 기반으로서 정합되며, 서비스경제를 육성시킬 수 있는 철학적 프레임이 된다.

창조경제를 내세운 박근혜 정부는 인력채용에 있어서도 학벌, 스펙 위주의 인재선발을 지양한다. 따라서 공공기관이나 기업이 창조경제를 뒷받침할 만한 인재선발을 추진하고 있다. 이를 위해 도입한 방식이 국가직무능력표준 이다. 특히 IT분야는 전 공공기관에서 인재가 필요하다. 따라서 본 논문은 국가직무능력표준의 IT인재 부문을 연구하고, 국가직무능력표준을 적용한 IT인재 선발에 대해 분석한다. 본 논문은 국가 공공기관 뿐만 아니라 창조 경제를 발휘하는 기업에서 필요한 IT인재상에 대한 중요한 연구 자료가 될 것이다.

In Korea, various community investment renewable project models are being implemented to increase community acceptance of renewable energy. An important factor for enhancing local acceptance is that renewable energy projects have a positive effect on revitalizing the local economy such as income increase or job creation for residents and local companies. To maximize the local economic effect of large-scale community investment renewable energy projects, this study developed an evaluation index for local economy activation, whose indicators are the local return on investment, local companies' participation, local job creation, regional cooperation, transparency, and governance. Analysis of existing evaluation indicators and current renewable projects, financial analysis, and expert interviews were used in this research. The pilot evaluation determined that, the local economic effect was high in the following order: a fund investment wind project (Gangwon), benefit-sharing wind project (Jeju), and general wind project. In particular, residents' investment amount, the number of participating residents, and the amount and transparency of the regional cooperation fund were key factors to expand the effect of local economy activation. This evaluation index could be used in public bidding for renewable energy projects such as offshore wind zoning areas of local government.

The global economy has been very difficult due to the recent impact of COVID-19. Korea is also pushing for strong quarantine policies such as K- quarantine and social distancing, but the economy is hardly recovering. In particular, the economic situation began to change rapidly depending on the export and domestic market, the public's interest in the economy increased, and companies became more sensitive. In order to estimate this rapidly changing economic situation, major advanced countries have also developed models that can periodically monitor the economy at the government level. Through this, by periodically reporting the economic trends, the public and companies can be aware of the economic trends to some extent. This study analyzed the cases of weekly business trends in advanced countries and developed a model of weekly economic activity suitable for Korea. To verify this, indices closely related to the economy such as mobility, industrial activity, face-to-face consumption, and psychology were discovered and estimated. As a result of the study, the weekly economic activity index was judged to be very useful in capturing short-term real economic activity. In the future, in order to secure the robustness and stability of the index and to increase the reflection of reality, model improvement and parameter estimation should be performed regularly.
