  • The diel swarming of Moina macrocopa and the relationship between environmental factors were evaluated in a shallow reservoir. The littoral density of Moina macrocopa maintained low from night to noon, reached maximum density at the afternoon with compact swarms at the waters' edge, and dispersed after sunset. The recruitment of Moina macrocopa and changes of water temperature (r=0.709, p<0.001) and juvenile fish density (r=0.511, p=0.002) in the littoral zone showed a significant positive relationships. After the induction of diel horizontal migration toward littoral zone, therefore, direct juvenile fish predation pressure should be induced Moina macrocopa swarming.

  • Most living organisms synchronize their physiological and behavioral activities with the daily changes in the environment using intrinsic time-keeping systems called circadian clocks. In mammals, the key molecular features of the internal clock are transcription- and translational-based negative feedback loops, in which clock-specific transcription factors activate the periodic expression of their own repressors, thereby generating the circadian rhythms. CLOCK and BMAL1, the basic helix-loop-helix (bHLH)/PAS transcription factors, constitute the positive limb of the molecular clock oscillator. Recent investigations have shown that various levels of posttranslational regulation work in concert with CLOCK/BMAL1 in mediating circadian and cellular stimuli to control and reset the circadian rhythmicity. Here we review how the CLOCK and BMAL1 activities are regulated by intracellular distribution, posttranslational modification, and the recruitment of various epigenetic regulators in response to circadian and cellular signaling pathways.

  • Port Authority in Korea does not have financial independence nor fair recruitment practices, thus the prospects of the establishment of the Port Authority is not adequate. Therefore independent and effective port administration cannot be achieved. To overcome this situation, this paper examines the port administration system in Korea and identifies its problems. This paper then provides an 'modeling of Analytical Hierarchy structure' for evaluation. An alternative solution is provided by carrying out a public survey, analysing the significance of the evaluation factor using the techniques of the Analytical Hierarchy Process. The significance of profitability was identified. The role of central government is significant when assessing the public service function of port administration; and the role of the private company is significant when assessing the independence. In addition, the private company is significant when assessing profitability. The private company is the alternative for port administration in Korea, based on the evaluation of various alternatives.

  • This study analyzed tourists' intention at Gangcheon Mountain, Sunchang-gun for local tourism. The contents of study included impression, characteristics, specialized resources, development direction, intention of visit and its form, destination prior and post visit, travelling expenses, and development form of tourism. The results were as following. Impression and characteristics showed that gochujang and fermentation industry established a strategic ground of local development. Intention of revisit of tourists was relatively high by 97.1%. Furthermore, tourists were mainly family units and they preferred family-based recreational type for the future local tourism development form. Therefore, a development strategy will be required that involves inexpensive accommodation, unique local food items, agricultural-specialty products and local tour packages. For invigoration of local tourism, recruitment of skilled managers for farm village experience will be necessary as well.

  • Railway system is a word that includes rolling stock, railway infrastructure and signalling System in passenger transfer and rail freight. This system get higher competitiveness in energy efficiency part than other transfer system. But it is comprehensive system has latent loss of lives and property by big accident. First of all, to control this comprehensive system and to confirm safety of it, we need human resource management. This research will suggest how to apply efficiency safety verification and certification system to railway system. human resource management systems is defined as three kinds that is recruitment and management, ensure personnel's competencies and fitness, activity of assigning suitable responsible person for work.

  • Insulin stimulates glucose uptake in muscle and adipose cells primarily by recruiting GLUT4 from an intracellular storage pool to the plasma membrane. Dysfunction of this process known as insulin resistance causes hyperglycemia, a hallmark of diabetes and obesity. Thus the understanding of the mechanisms underlying this process at the molecular level may give an insight into the prevention and treatment of these health problems. GLUT4 in rat adipocytes, for example, constantly recycles between the cells surface and an intracellular pool by endocytosis and exocytosis, each of which is regulated by an insulin-sensitive and GLUT4-selective sorting mechanism. Our working hypothesis has been that this sorting mechanism includes a specific interaction of a cytosolic protein with the GLUT4 cytoplasmic domain. Indeed, a synthetic peptide of the C-terminal cytoplasmic domain of GLUT4 induces an insulin-like GLUT4 recruitment when introduced in rat adipocytes. Relevance of these observations to a novel euglycemic drug design is discussed.

  • This article presents how in China mainland a school and a school district find their science teachers. Based on studying relevant materials and years of intensive involvement in teacher education and recruitment practices the authors draw three features of the current secondary science teachers' employment system in China mainland: certification control conducted very loosely selection criteria and process vary with schools and school districts due to the remarkable difference existed among them the normal universities/colleges established originally only for secondary science teacher education still play a vital role in shaping effecting quality of teacher candidates although no one of them for a long time have focused on only doing what they were supposed to do. For further development, changes and essential reform are expected duo to the increasing promotion toward the internal quality of education and therefore high quality of teachers and teacher candidates.

  • Topics discussed in this paper are engineering design of artificial reefs, design considerations of compressive strength and pH, materials of silica fume concrete and volcanic stones for reef construction, and field monitoring of artificial reefs. Six artificial reefs were deployed offshore at Biyangdo in July 2006, and succession patterns on the reefs were investigated bimonthly from July 2006 to October 2007. The spore-bag method, which has been widely used in Korea for the attachment of seaweed on artificial reefs, was applied to the developed reefs using the kelp Ecklonia cava, which is the dominant species in Jeju, and recruitment and growth patterns were observed.

  • 기업에 있어서 가장 기본이 되는 HRM은 다른 업무에 비해 사각 지대에 있다. HRM 부문도 기업에 미칠 정보기술에 대해서 많은 관심이 필요하며, 정보화 사회의 미래를 보며 남보다 앞서갈 수 있는 조직, 기업을 만들 기회를 선점해야 한다. 즉 생산방식의 변화, 정보화, 지식사회, 서비스산업 팽창, 경쟁의 심화, 세계화, 국제화 등 많은 수식어로 묘사되는 최근의 환경변화는 기업의 생존과 성패가 물적 자원보다는 인적자원에 더욱 의존하게 된다. 본 고에서 디지털시대에 있어서 기업의 인적자원 경쟁력의 결정적 기반이 될 수 있는 e-HRM의 기본 개념 변화, 모형 그리고 도입절차 및 성공요인에 대해 살펴보고자 한다.
