Transition metal ions including Se2, Cd2, Hg2 or Mn2 have been thought to disturb the bone metabolism directly. However, the mechanism for the bone lesion is unknown. In this study, we demonstrated that MC3T3E1 osteoblasts, exposed to various transition metal ions; selenium, cadmium, mercury or manganese, generated massive amounts of reactive oxygen species (ROS). The released ROS were completely quenched by free radical scavengers-N-acetyl cysteine (NAC), reduced... -

하악의 대구치는 저작의 중추적인 역할을 하는 부위로 맹출 이후 가장 많은 교합력을 받는 부위이다. 이로 인해, 구강내에서 가장 먼저 상실되는 치아이기도 하다1,2). 하악에서 양측성으로 구치부가 탈락하여 후방연장 국소 의치를 제작하는 경우 많은 임상적인 문제점이 발생한다. 유리단 부위 치조제의 계속적인 흡수, 구치부의 불안정 으로 인한 교합의 부조화, 연조직의 통증 등이 발생하게 된다3-6). 이는 후방연장 국소의치의 역학적인 불리함에 서 기인한다고 할 수 있다7). 유리단 부위가 길어질수록 mechanical advantage는... -
A Model to Explain Temperature Dependent Systemic Infection of Potato Plants by Potato virus Y
한국식물병리학회 The Plant Pathology Journal 6 Pages
한국식물병리학회 The Plant Pathology Journal 2017, 33권 2호 12 206-211 (6 pages)
The effect of temperature on the rate of systemic infection of potatoes (Solanum tuberosum L. cv. Chu-Baek) by Potato virus Y (PVY) was studied in growth chambers. Systemic infection of PVY was observed only within the temperature range of 16°C to 32°C. Within this temperature range, the time required for a plant to become infected systemically decreased from 14 days at 20°C to 5.7 days at 28°C. The estimated lower thermal threshold was 15.6°C and the... -
Development and Evaluation of Loop-Mediated Isothermal Amplification Assay for Rapid Detection of Tylenchulus semipenetrans Using DNA Extracted from Soil
한국식물병리학회 The Plant Pathology Journal 9 Pages
한국식물병리학회 The Plant Pathology Journal 2017, 33권 2호 10 184-192 (9 pages)
Tylenchulus semipenetrans is an important and widespread plant-parasitic nematode of citrus worldwide and can cause citrus slow decline disease leading to significant reduction in tree growth and yield. Rapid and accurate detection of T. semipenetrans in soil is important for the disease forecasting and management. In this study, a loop-mediated isothermal amplification (LAMP) assay was developed to detect T. semipenetrans using DNA extracted from soil. A set of five primers was designed from... -
A Choice of Nightmares: The Fisher King and the Horror in Heart of Darkness and Apocalypse Now
Youngkul Kim 이화여자대학교 교과교육연구소 Eastwest Education 46 Pages

This study investigates Joseph Conrad's Heart of Darkness and its film adaptation, Francis Ford Coppola’s Apocalypse Now, by examining the character of the Fisher King, a common figure at the beginning of human society who was later incorporated into romance literature, especially in the quest for the Holy Grail in the Arthurian legend. A superior warrior of godlike proportions, he leads his people to health and prosperity; as Fisher King, however, he becomes sick, and that sickness is... -
글로벌 커뮤니케이션 그룹과의 인수 및 합병 이후 나타난 한국 광고회사 내부의 변화에 대한 연구
유현재 한국광고PR실학회 광고PR실학연구 29 Pages
한국광고PR실학회 광고PR실학연구 2011, 제 4권 1호 1 7-35 (29 pages)
본 연구는 최근 WPP 등 글로벌 커뮤니케이션 그룹과의 합병을 경험한 한국 광고대행사들의 직원들이 당시 느꼈던, 그 리고 현재도 경험하고 있는 실제 업무 스타일의 변동, 회사에 대한 로열티 등에 대한 감정변화 등 합병 이후 불거진 상 황들에 대해 심층적으로 조사해 보고자 하였다. 연구 결과, 대부분의 구성원들은 영어에 대한 스트레스와 함께 실력향 상을 위한 자구노력을 다하고 있었으며, 합병 이전과 비교하여 현재 근무 중인 회사에 대한 충성도와 회사를 통한 자신 의 미래 비전에 대해 회의적인 시각을 보인 경우가 많았다.... -

Three-dimensional porous graphene materials for environmental applications
Muruganantham Rethinasabapathy, Sung-Min Kang, Sung-Chan Jang, Yun Suk Huh 한국탄소학회 Carbon Letters 13 Pages

Porous materials play a vital role in science and technology. The ability to control their pore structures at the atomic, molecular, and nanometer scales enable interactions with atoms, ions and molecules to occur throughout the bulk of the material, for practical applications. Three-dimensional (3D) porous carbon-based materials (e.g., graphene aerogels/hydrogels, sponges and foams) made of graphene or graphene oxide-based networks have attracted considerable attention because they offer low... -
Effect of acid catalysts on carbonization temperatures for ordered mesoporous carbon materials

their high porosity, high surface area and controllable regular pore-structure [1-6]. Successful synthesis pathways for obtaining OMC materials include the direct synthesis of OMC materials through the organic-organic self-assembly method (soft templating process) and nano-replication of OMC materials from mesoporous silica templates (hard templating process) [7-11]. The direct synthesis method is suitable for large-scale production of carbon materials due to its easier process compared to the... -

Graphite can be classified into natural graphite from mines and artificial graphite. Due to its outstanding properties such as light weight, thermal resistance, electrical conductivity, thermal conductivity, chemical stability, and high-temperature strength, artificial graphite is used across various industries in powder form and bulk form. Artificial graphite of powder form is usually used as anode materials for secondary cells, while artificial graphite of bulk form is used in steelmaking...
