  • We surveyed the freshwater invertebrates of Jindo Island twice on July and September 2016, as part of a joint faunal survey conducted to commemorate the 30th anniversary of the Korean Society of Systematic Zoology. Aquatic insects were not included in this study. We found 38 freshwater species from seven phyla: Porifera, Platyhelminthes, Nematomorpha, Mollusca, Annelida, Arthropoda, and Bryozoa. Twenty-one of the 38 species (55.3%) represented the first record of their respective species on Jindo Island. Among these species, a freshwater shrimp-parasitic isopod, Tachaea n. sp., was identified as a new species.

  • These experiments tested whether exposure to benomyl (BN) or lindane (LD) during late pregnancy affect the development of reproductive tract in adult offspring. Timed pregnant Sprague Dawley rats (N=7∼8/treatment) were gavaged with LD (1, 5, or 10 mg/kg), BN (50, 250, or 500 mg/kg), or com oil on gestation days 15∼19.(omitted)

  • This paper presents an economic analysis for alternatives of the building telecommunications cabling system to accommodate multimedia services. Four alternatives are developed with respect to capacities of the building telecommunications cabling systems. Economic analysis includes qualitative analysis as well as quantitative one and the results of those analyses are incorporated with AHP(analytic hierarchical process) method. In analyzing the alternatives, based on the possible growth of multimedia traffic and evolution of access networks, various scenarios are considered. The results suggest not only the most competitive alternative but also the conditions for each alternative to gain the competitive edge.

  • The molecular mechanisms that arrest cardiomyocytes in the cell cycle during postnatal period remain largely unknown. The activity of CDKs control cell cycle progression, and this activity is regulated positively and negatively by association of CDKs with cyclins and cyelin dependent kinase inhibitors (CKIs) respectively.(omitted)

  • 본 연구에서는 2011년에 설립된 부산과학고등학교 별샘천문대에 있는 32인치 반사망원경을 비롯한 여러 천체망원경들을 간단히 소개하고 관측을 통해 성능을 분석하여 향후 교육과 연구에 활용할 수 있는 기초 자료를 제공하고자 한다. 관측기기들의 기계적인 특성을 분석하기 위해 가대의 추적 특성과 정밀도, 지향특성 등을 조사한다. BVI 표준성 관측을 통한 표준계 변환 결과를 제시하고, 한계등급에 대해 고찰한다. 이를 통해 32인치 주망원경과 기타 보조 망원경 및 교육용 기자재를 활용하여 관측할 수 있는 주제를 모색하고 그 한계를 제시한다.

  • We study on the Electro Optical Properties of the EEFL (External Electrode Fluorescent Lamp) Backlight system is based on the lamp type characteristics and diameter of the lamp tube under the equal manufacturing of the lamps. In this contribution, through the analysis of the different lamp type and diameter of the lamp tube gain the effective luminance and reduce the lamp voltage from aspect in the electro optical properties with EEFL and LCD backlight system.
