도시광산산업 통계는 도시광산산업을 체계적으로 육성하기 위해서 가장 기본적으로 필요한 자료이며 산업현황을 이해하는데 중요한 수단이다. 본 연구에서는 국가통계를 활용하는 Top-down 방식과 개별 기업현황 조사를 하는 Bottom-up 방식을 병행한 통계조사 방법을 통하여 도시광산 재자원화 규모 및 업체 현황을 조사하였다. 그 결과 도시광산 재자원화 규모는 19.6조 원으로 국내 금속수요의 약 22%를 도시광산에서 공급하고 있었다. 또한 도시광산 업체는 917개로 수도권과 경상권에 대다수 분포하고 있었으며, 약 58%의 업체가 10인 이하의 소기업으로 조사되었다. 2009년 도시광산 업체 현황 조사결과와 비교하였을 때, 도시광산 업체수는 전반적으로 증가하였고, 특히 희소금속 관련 기업 수의 증가 폭이 컸다. 본 연구는 기존의 간접적인 도시광산 통계 결과와 달리 실제 도시광산 업체에서 생산되는 금속자원 규모 및 관련 업체에 대한 통계자료를 산정하여 제시했다는 점에서 연구의 차별성 및 의의를 지닌다. Statistics on the urban mining industry is the essential information to develop the urban mining industry systematically and the prerequisite way to understand its related trends. Status on domestic urban mining industry was thus investigated through the integrated method which uses both the top-down way based on the national statistics utilization and the bottom-up way based on field data gathering. Results indicated that the scale of metal resources produced through domestic urban mine was 19.6 trillion won, which corresponds to approximately 22 percent of metal demand in korea. The number of firms for urban mining was 917, and they are mostly placed in metropolitan area and Gyeongsang province. It was also found that about 58 percent of urban mining firms was in small business level less than 10 employees. Compared to the results in 2009, the number of urban mining companies in 2014 generally increased, and that of rare metal companies grew up significantly. This study is particularly different from the conventional statistics investigation on the point of the actual scale findings of metal resources based on the field data.

In Korea, a good recycled product (GR) certification system was introduced in 1997 to improve resource and energy use efficiency. However, in industry and society, recycled products are not used well because of the lack of awareness of recycled materials. In this study, the status of domestic and international quality standards for nickel materials was investigated, and the purity and electrochemical properties of nickel sulfate prepared from ore and nickel sulfate recovered from waste lithium-ion batteries were evaluated during the electroplating process. As a result of the test, it was found that there is no quality difference between recycled nickel sulfate and high-purity nickel sulfate reagents when used in the electroplating industry.

In spite of an increasing demand on the detailed information on climate change, future climate projections for Korean waters have been conducted very limitedly. Even for the regional climate projections, most of the previous studies used a regional ocean-only model forced by a global model projection result for the atmosphere and thus could not properly simulate the air-sea interactions on a high resolution. The goal of this study is to develop a regional climate coupled model (RCCM) for the Northwest Pacific and present a future climate projection in Korean waters with including high-resolution air-sea interaction effects. In this paper, we present preliminary results focusing on sea surface temperature (SST) changes projected for Korean waters using the RCCM developed for the Northwest Pacific. The RCCM consists of an ocean model, Regional Ocean Modeling System (ROMS) and an atmospheric model, Weather Research Forecast (WRF). The projection results show some prominent features such as a considerable surface warming in the East Sea relative to the Yellow and East China Sea and a stronger warming in summer than in winter. Compared to the ocean-only model result, the RCCM result shows a significant difference in the projected SST, especially in the Yellow Sea, implying that the regional climate modeling allowing air-sea interaction can have a considerable influence on a future climate change projection.

With the development of the manufacturing industry, ``Servitization`` and ``Convergence of Industries`` have been spread. In the middle of these changes, a collaborative network of companies have come to be noticed. This study presents ‘a performance mechanism of servitization’ based on the collaborative network which is derived through literature review of servitization and network organization theories. Then we carried out empirical research to verify how the performance mechanism works in the domestic industry. Our model explains the process that network relationship among members and collaborative capabilities are built by service-oriented culture in a focal firm, and then servitization performance are facilitated by those factors. Also, service-oriented organizational culture enhances the network relationship and capabilities. Our survey instrument was developed based on the constructs for the mechanism. The questionnaire was developed using a Likert`s 7 point scales and included some demographical data. 300 survey records were collected. 247 among them was considered valid for the analysis. Reliability test and validity test results confirms all related data were acceptable for the path analysis. Through the hypothesis, hypothesis H4(network relationship will affect servitization performance) was dismissed. this result concurred with the claims that korean manufacturing industries are characterized by vertical integration of large conglomerates and subcontracting relationship, and there has been many obstacles to make synergies between the large and small businesses. Hypothesis H1(Service-oriented organizational culture → Network relationship), H2(Service-oriented organizational culture → Network capabilities), H3(Network relationship → Network capabilities), H5(Network capabilities → Servitization performance) of the structural equation model is positively confirmed. Results show that network relationship has a mediation effect on the servitization performance via network capabilities. Overall, the superiority of our structural equation model was confirmed. This study extended the research opportunities of servitization with the network perspectives. Also, this study will provide management with strategic insights for preparing servitization strategy and self assessment chances.

아웃소싱이 보편화되고 전략적 중요성이 대두되면서, 아웃소싱의 영역 또한 경영지원 및 시설관리 등의 간접 지원활동에서 제조, 연구개발 및 마케팅 등 고부가가치를 창출하는 핵심영역으로 확장되고 있다. 아웃소싱의 목적도 과거에는 비용절감에 치우쳤으나, 기업기능의 전문성 확보, 신속한 제품개발 및 유연성 개선과 같이 점차 다양해지고 있다. 하지만 기업기능별 아웃소싱과 기업성과와의 관계를 체계적이고 종합적으로 고찰한 연구는 부족한 현실이다. 따라서 우리는 대한민국 제조기업을 대상으로 가치사슬 내의 주요 기업기능(기업경영 및 관리, 제품기획 및 연구개발, 제품생산 및 공정, 제품판매 유통 및 사후관리)별 아웃소싱이 기업성과에 미치는 영향을 실증적으로 분석하였다. 기업성과는 총 7가지 항목(전략, 재무, 고객, 비용, 유연성, 품질, 시간성과)으로 측정하였고, 기능별 아웃소싱과 기업성과의 긍정적 관계가 미래의 아웃소싱 비중에 미치는 매개효과를 분석하였다. 분석결과 우리나라 제조기업은 기업기능별 아웃소싱을 통하여 전략성과(신제품 개발 및 신성장동력 창출)와 시간성과(제품개발 및 생산시간 단축)에서 주로 긍정적인 효과를 보는 것으로 나타났다. 하지만 미래 아웃소싱의 비중에 대한 의사결정은 기업성과에 영향을 받기보다, 과거 아웃소싱 비중에 직접 영향을 받는 것으로 나타나, 아웃소싱을 적극 활용하는 기업일수록 이에 대한 의존도가 점차 심화될 위험성이 있는 것으로 나타났다. The scope of outsourcing has continually expanded from support activities to primary functional activities such as operations, marketing and R&D. Firms today outsource not only to reduce costs, but also to acquire process technology, improve product quality, and enhance flexibility. The literature on functional outsourcing is rather scant, overlooking the fact that outsourcing by functions may induce different effects on alternative performance indicators. We empirically explore the impacts of functional outsourcing on diverse operational and firm performance measures, using the data collected from Korean manufacturing firms. Four functions were investigated: business planning and general management, product design and R&D, manufacturing and process, and distribution and logistics. The empirical findings indicate that Korean manufacturing firms have benefited from improvement in strategic and time performances, capitalizing on outsourcing of primary business functions. However, future outsourcing decisions are mainly affected by the degree of past outsourcing rather than outsourcing performance. Thus, manufacturing firms must take a cautious approach in initiating outsourcing of primary functions since it may increase switching cost and dependency on outsourcing.

Since its introduction as an alternative intestinal lengthening technique, the serial transverse enteroplasty (STEP) procedure has been used increasingly as the surgical treatment of choice for children with short bowel syndrome (SBS). On the other hand, there are few report of its efficacy in adults with SBS, particularly those who have previously undergone a gastrectomy. This case report describes a 34-year-old woman with a short bowel after an esophagectomy and total gastrectomy due to lye ingestion followed by an extensive intestinal resection due to small bowel strangulation. The STEP procedure was performed successfully and the small intestine was lengthened from 55 to 75 cm. The patient tolerated the procedure well and was weaned off total parenteral nutrition. The frequency and characteristics of diarrhea improved, and her weight remained acceptable via management with intermittent parenteral nutritional support for 6 months postoperatively. This case suggests that the STEP procedure should be considered for gastrectomized patients with SBS.
