Limited epidemiologic data is available regarding the cardiovascular effects of mercury exposure. The purpose of this study was to determine the relationship between mercury exposure from fish consumption and cardiovascular disease in a nationally representative sample of Korean adults using the Fourth Korea National Health and Nutrition Examination Survey (KNHANES IV 2008~2009). Survey logistic regression models accounting for the complex sampling were used to estimate the odds ratios (OR) adjusted for fish consumption frequency, age, education, individual annual income, household annual income, body mass index (BMI), waist circumference (WC), alcohol consumption status, and smoking status. The mean blood mercury level in the population was $5.44{\mu}g/L$. Trends toward increased blood mercury levels were seen for increased education level (P=0.0011), BMI (P<0.0001), WC (P<0.0001), and fish (i.e., anchovy) consumption frequency (P=0.0007). The unadjusted OR for hypertension in the highest blood mercury quartile was 1.450 [95% confidential interval (CI): 1.106~1.901] times higher than that of the lowest quartile. The fish consumption-adjusted OR for hypertension in the highest blood mercury quartile was 1.550 (95% CI: 1.131~2.123) times higher than that of the lowest quartile, and the OR for myocardial infarction or angina in the highest blood mercury quartile was 3.334 (95% CI: 1.338~8.308) times higher than that of the lowest quartile. No associations were observed between blood mercury levels and stroke. These findings suggest that mercury in the blood may be associated with an increased risk of hypertension and myocardial infarction or angina in the general Korean population.

본 논문은 청동기와 인문경도, 원시자기 같은 희소자원의 생산, 유통을 사례로 들어 상대 전 중기에 자원문제가 중심과 주변의 관계에 미친 영향을 논하였다. 중심과 주변의 관계는 상문화 구역 내부에서의 관계, 상문화 구역 외부에서의 관계 등으로 나누어 살펴볼 수 있다. 상문화 구역 내부에서는 지방에서 생산된 인문경도와 원시자기 등의 자원을 반룡성에서 취합한 후 정주상성으로 운반하였다. 그러나 반룡성에서는 자체적으로 청동기를 생산하거나 인문경도와 원시자기를 독자적인 방식으로 사용하는 현상도 확인된다. 반룡성은 자원 획득의 성격을 지닌 비교적 독립적인 거점이었다. 상문화 구역의 외부에서는 정주상성에서 성양지역으로 청동기 완제품이 유통되었으며, 청동 원료도 유통되었을 것이다. 남방 복건 강서지역의 인문경도와 원시자기는 반룡성을 통해서 중원지역으로 유입되었는데, 각 지역에서 인문경도와 원시자기의 기능과 의미는 다르게 사용되었다. 이상을 통해서 상문화구역 내부와 외부에서 중심과 주변 간의 자원유통은 쌍방향적이었으며, 이러한 자원의 유통은 중심과 주변의 관계를 형성하는 중요한 요소였음을 알 수 있다.

Purpose: The purpose was to compare operating room (OR) nurses and general ward nurses on their communication competence and interpersonal relationship ability within the medical team. Methods: Participants were 276 nurses (OR 122, ward 154) working in one of 4 university hospitals located in I and K areas. Data were collected using a questionnaire and data collection was done in June, 2013. Comparisons between OR nurses and general ward nurses on communication competence and interpersonal relationship ability were analyzed using ANCOVA. Results: There were statistically significant differences between the two groups in communication competence (F=11.96, p=.001) with average score for OR nurses at 3.37 points and ward nurses at 3.53 points. There were statistically significant differences between the two groups in interpersonal relationship ability (F=15.51, p<.001) with the average score for OR nurses at 3.30 points and ward nurses at 3.50 points. Conclusion: The results indicate a need to develop a variety of programs to promote communication competence in OR nurses and to enhance the openness of interpersonal relationship ability in human resource management.

Purpose - An appreciable number of small- and medium-sized exporters have continuously succeeded in their export marketplaces even though they do not possess enough resources. Advocating that affiliation with an export service-provider plays an important role in this phenomenon, we aimed to theoretically explain how export service providers' competences and relational factors drive small- and medium-sized exporters' competitive advantages in the long-run. Design/methodology - Drawing prominently on the resource-based view and the relationship-marketing theory, we built an empirically testable model. The model showed the roles of exporter capabilities, export service-provider competences, and relational factors on small- and medium-sized exporters' sustainable competitive advantages. Findings - The results of our research showed that exporter production and branding capabilities positively influenced their sustainable competitive advantage. In addition, export service-providers' marketing competence and relationship-building competence positively moderated the effects of exporter capabilities on their parties' sustainable competitive advantages. Finally, affiliation parties' interfirm trust and relationship commitment positively moderated the effects of export service-provider competence on the relationship between exporter capabilities and sustainable competitive advantages. Originality/value - Although prior studies have highlighted the effects of an exporter's resources on export performance, our research filled a knowledge gap of the effects of other resources on export performance. First, we proposed two types of export service-provider, competence marketing and relationship-building, influencing exporters' competitive advantage. Second, the effects of relational factors were proposed in the context of export affiliations.

사회적 자본과 관련한 기존의 연구들은 주로 사회적 자본이 혁신성과에 미치는 영향을 규명해 왔다. 그러나 이러한 선행연구들은 사회적 자본이 혁신성과에 어떠한 단계를 거쳐 영향을 미치는가에 관한 중간과정을 블랙박스(black box)로 가정하고 있다. 지식기반관점에 따르면 혁신은 상호의존 관계에 있는 행위자들 간의 지식의 교환과정의 결과로써 가능할 수 있다. 다른 의미로, 혁신창출은 사회적 자본과 같은 무형자원이 구성원 간의 지식관리 활동을 유발하게 되고, 이러한 지식관리 활동은 혁신창출의 원동력이 된다. 그리고 혁신달성을 통한 관계만족이 지속적인 관계투자를 가능하게 할 수 있다. 따라서 본 연구는 사회적 자본에서 출발하여 관계투자로 이어지는 연구가설을 설정하였다. 실증분석의 결과를 살펴보면, 혁신 성과에 미치는 지식공유의 영향을 제외하고, 모든 설정된 가설은 유의적인 영향을 미치는 것으로 나타났다. 또한 혁신 성과 달성은 중소기업에게 관계만족을 증가시켜 지속적인 관계투자를 가져오는 것으로 나타났다. 본 연구는 경영전략 측면에서 기업의 지식관리 활동의 중요성을 제시하고 있다.

In this work, we analyzed correlations between life-cycle greenhouse gas (GHG) emissions and life-cycle cost of energy resources. Energy resources studied in this paper include coal, natural gas, nuclear power, hydropower, geothermal energy, wind power, solar thermal energy, and solar photovoltaic energy, and all of them are used to generate electricity. We calculated the mean values, ranges of maximum minus minimum values, and ranges of 90% confidence interval of life-cycle GHG emissions and life-cycle cost of each energy resource. Based on the values, we plotted them in two dimensional graphs to analyze a relationship and characteristics between GHG emissions and cost. Besides, to analyze the technical maturity, the GHG emissions and the range of minimum and maximum values were compared to each other. For the electric generation, energy resources are largely inverse proportional to the GHG emission and the corresponding cost.

The purpose of this study is to investigate the role of IT-enabled dynamic capability in the relationship between intellectual capital and innovation performance under Industry 4.0. We approach the intellectual capital from the perspective of the resource-based view and define the components of intellectual capital as human capital, social capital, and organizational capital. On the other hand, the IT-based dynamic capability means that the information technology and the utilization ability of the enterprise are combined to overcome the turbulent environment. The empirical results showed that the IT-enabled dynamic capabilities mediated the relationship between intellectual capital and innovation performance as it revealed in theory. And in terms of practical implications, we found the importance of an organization's information technology ability to effectively utilize intangible resources for organizational performance.
