최근 중국은 양산항을 개장하여 선사 유치를 위한 다양한 혜택을 제공하고, 일본은 "수퍼중추항만 육성계획“을 세워 항만의 효율성을 바탕으로 비용을 낮추려는 노력을 하고 있다. 또한 선박의 대형화에 의한 중심항만(Hub Port) 위주의 기항과 북중국의 대량 물량 발생지역에 대한 직기항 경향으로 동북아 항만간의 경쟁이 더욱더 치열해 지고 있으며 동북아 역내 피더네트워크 강화의 필요성이 제기되고 있다. 따라서, 본 연구에서는 유럽 피더네트워크 전략 사례를 바탕으로 동북아 피더시장 현황을 파악하고 동북아 피더네트워크 구조를 분석함으로써 동북아 역내 항만 및 선사간의 과당경쟁을 지양하고 서로 Win-Win할 수 있는 터미널의 전략적 활용, 선사간 제휴 확대, 항만간 협력 강화를 위한 구체적인 전략을 제시하였다. Recently, China opened Yangshan port and provides a variety of benefits for shipping companies. Japan plans to reduce logistics costs and improve efficiency through the established "super major ports" project. According to the "hub and spokes" system, the number of direct calls toward North-Chinese ports are increasing. This changing environment has negative effects on the amount of transshipment cargos in Korean ports. In order to make a hub port of a domestic port, it is necessary to develop northeast Asian feeder networks. Therefore, this paper analyzes the structure of northeast Asian feeder networks through the case study of European feeder networks strategy. Finally, we suggests the plans to reinforce feeder networks, which are strategic terminal operation, strategic alliances between shipping companies and port co-operation, for win-win strategy in the competitive northeast Asian market.

The Candlelight Vigils in South Korea: Neoliberal Protestors with National-Democratic Discourses

( Jun Hyeok Kwak ),( Gye Won Jo ) 대한정치학회 2011 大韓政治學會報 Vol.18 No.2

이 논문의 목적은 한국의 2008년 촛불집회에서 나타난 정치행위자의 한계를 ``시민적 책임성``이라는 측면에서 비판적으로 검토하는 것이다. 미국산 쇠고기 수입반대 촛불집회에 대해서는 서로 다른 두 가지 해석이 존재한다. 하나는 이 시위가 ``다중`` 또는 ``집단지성``이라는 새로운 정치행위자의 출현을 예시하며 새로운 형태의 민주주의가 도래했음을 보여준다는 해석이다. 다른 하나는 촛불시위는 제도화될 수 없는 반정치적이고 민중주의적인 운동이라는 회의적 시각이다. 비록 두 가지 해석들은 촛불집회에서 나타난 정치행위자나 운동 형태에 대해 흥미로운 설명을 하고 있지만, 촛불집회와 같은 대중적 사회운동이 최초에 예상되었던 정치사회적 변화를 결과하지 못하고 갑자기 사라진 이유를 만족스럽게 설명하지 못하고 있다는 비판으로부터 자유롭지 못하다. 이런 전제에서, 이 논문은 그 원인을 부분적으로 한국 사회의 후기 민주주의적 특성과 신자유주의적 변화에서 찾으려고 한다. 구체적으로 두 가지 주장을 피력된다. 첫째, 촛불시위는 개인화된 정치행위자들과 한국 사회에서 오랫동안 구조화된 민족주의적·민주적 담론이 접합되어 나타난 현상으로 볼 수 있다는 것이다. 둘째, 촛불시위는 시민적 책임성 없이 드라마틱한 이슈에만 즉흥적으로 반응하는 후기 민주주의의 원자화된 개인들의 정치적 삶이 지닌 한계를 보여준다는 것이다. This paper explores the limit of a political agency as an impromptu aggregation of individuals in the context of civic responsibility. The 2008 anti-U.S. beef Candlelight Vigils in South Korea have generated two opposite interpretations: some regard the protests as the advent of the ``multitude,`` or ``collective intelligence`` that foreshadows the emergence of a new type of democracy, while others denounce them as anti-political populist movements which cannot be institutionalized. Of particular concern here is the reason why such a mass social movement disappeared abruptly without leaving any social repercussion. We argue that the volatility of the movement is in part attributed to the society`s neo-liberal changes as well as post-democratic features. We also interpret the appeal of participants to popular sovereignty as an articulation of neoliberal individualization with nationalistic-democratic discourses. The Candlelight Vigils showed the internal discrepancy of the citizen who oscillates between collective political agency only reacting to dramatic issues and the atomized neo-liberal individual without civic responsibility.

This study aimed to investigate the association between Bacille Calmette-Guérin (BCG) vaccination and nontuberculous mycobacterial pulmonary disease (NTM-PD). Patients in the prospective NTM-PD cohort were matched to healthy controls to measure the association between BCG and NTM-PD development. The clinical course of NTM-PD patients was also evaluated to investigate the association between BCG and NTM-PD progression. BCG scars were not associated with NTM-PD development (adjusted odds ratio [OR], 2.04; 95% confidence interval [CI], 0.96–4.34) or progression (adjusted OR, 1.61; 95% CI, 0.92–2.81). In conclusion, BCG vaccination was not associated with the development or progression of NTM-PD.

Maternal Social Separation of Adolescent Rats Induces Hyperactivity and Anxiolytic Behavior

Exposure to early stressful adverse life events such as maternal and social separation plays an essential role in the development of the nervous system. Adolescent Sprague-Dawley rats that were separated on postnatal day 14 from their dam and litters (maternal social separation, MSS) showed hyperactivity and anxiolytic behavior in the open field test, elevated plus-maze test, and forced-swim test. Biologically, the number of astrocytes was significantly increased in the prefrontal cortex of MSS adolescent rats. The hyperactive and anxiolytic phenotype and biological alteration produced by this MSS protocol may provide a useful animal model for investigating the neurobiology of psychiatric disorders of childhood-onset diseases, such as attention deficient hyperactive disorder.

Statins (3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors), which are cholesterol-lowering drugs widely used in the treatment of cardiovascular disease, cause adverse side effects in skeletal muscle ranging from fatigue to fatal rhabdomyolysis, leading to mitochondrial dysfunction. However, whether statins affect heart mitochondrial function is not clear. In addition, the effects of aerobic exercise training on mitochondrial function in statin-treated heart have not been clearly elucidated. Therefore, the purpose of this study was to determine the effects of in vivo atorvastatin treatment and aerobic exercise training on mitochondrial function (e.g., mitochondrial O2 respiration, H2O2 emission, Ca2+ retention capacity) in the rat heart. Male Wistar rats were randomly assigned to control (CON), 5 mg atorvastatin-treated group (STAT), and 5 mg atorvastatin treatment plus aerobic exercise group (STAT + EX) (N=12 rats/group). Animals were administered via oral gavage with a vehicle, 5 mg/kg/day atorvastatin dissolved in 0.25 % w/v hydroxypropyl methylcellulose for 12 weeks. The left ventricle (LV) was permeabilized by saponin for determination of mitochondrial respiratory capacity, mitochondrial H2O2 emission, and Ca2+ retention capacity. LV mitochondrial O2 respiration and Ca2+ retention capacity were not affected by 12 weeks treatment of atorvastatin. However, aerobic exercise training improved mitochondrial O2 respiration and Ca2+ retention capacity in LV. In contrast, mitochondrial H2O2 emission and Ca2+ retention capacity were reduced by exercise training. These data demonstrated that although LV mitochondrial function was not affected by atorvastatin treatment for 12 weeks, aerobic exercise training improved the mitochondrial function in the rat LV, suggesting that aerobic exercise training plays a pivotal role in improving mitochondrial function in the heart.

Effects of Safety Training and Leader Consideration Behaviors on Job-Related Injuries

Kwak.Won Jun 한국인적자원관리학회 2013 인적자원관리연구 Vol.20 No.1

근로자를 위한 안전교육의 중요성에 대한 관심이 많지 않다. 이에 본 연구에서는, 가정봉사원들을 위한 안전교육이 어떻게 그들의 업무관련부상에 영향을 주는지 조사하였다. 이와 더불어, 안전교육이 직속상사의 인간 중심적 배려행동과 상호작용을 통해 가정봉사원들의 업무관련부상에 미치는 영향도 함께 살펴보았다. 이 연구를 위하여 노인들을 위해 일하는 282명의 가정봉사원을 대상으로 설문조사를 실시하였고, 이를 통하여 얻은 자료에 대하여 다중회귀분석을 실시하였다. 분석 결과에 따르면, 예상했던 바와 같이 가정봉사원들이 더 많은 안전 교육을 받을수록 더 적은 부상을 직장에서 경험하는 것으로 나타났다. 또한, 상사가 더 많은 배려행동을 보였을 때에, 안전교육의 긍정적인 효과, 즉, 업무관련부상의 감소가 더욱 두드러짐을 알 수 있었다. 후행 분석에서는, 직속상사의 업무 중심적 행동은 배려행동이 가졌던 조절효과를 보이지 않았던 것으로 나타났다. 본 연구의 결과를 고려할 때, 가정봉사원들은 업무 중에 겪을 수 있는 부상을 예방하기 위해 적극적으로 안전교육을 받을 필요가 있다. 또한, 가정봉사원들의 상사도 단지 안전교육의 기회를 제공하는 것에 그치지 않고, 업무 중심적인 행동보다는 인간 중심적 행동을 보임으로써 안전교육이 더 효과적일 수 있게 도와야 할 것이다. The importance of the safety training for employees has not been paid to attention on. The present study investigated how safety training customized for home health aides would influence their job-related injuries. Then, it was further examined how the safety training would interact with their immediate supervisors’ consideration behaviors in predicting such injuries. With the sample of 282 home health aides working for senior people, it was found that, as expected, increased safety training resulted in decreased injuries on the job. Additional, it was also found that when supervisors demonstrated more consideration behaviors, home health aides under those supervisors were less likely to be involved in job-related injuries. In a post hoc analysis, supervisors’ initiative structure behaviors interacting with safety training were found not to have the same effects on home health aides’ injuries on the job. The study findings suggest that for reducing and preventing home health aides from being injured, it is necessary for their supervisors not only to provide safety training opportunities to home health aides, but also to be person-oriented rather than task-oriented.
