Antagonistic Activity of Bacteria Isolated from Apple in Different Fruit Development Stages against Blue Mold Caused by Penicillium expansum
Roc?o Crystabel L?pez-Gonz?lez, Yara Suhan Ju?rez-Campusano, Jos? Luis Rodr?guez-Ch?vez, Guillermo Delgado-Lamas, Sof?a Mar?a Arvizu Medrano, Ram?n ?lvar Mart?nez-Peniche, Juan Ramiro Pacheco-Aguilar 한국식물병리학회 The Plant Pathology Journal 12 Pages

Blue mold caused by Penicillium expansum is one of the most significant postharvest diseases of apples. Some microorganisms associated with the surface of ripen- ing apples possess the ability to inhibit the growth of P. expansum. However, the existing literature about their colonization in the stages before ripening is not explored in depth. This study aims to characterize the antagonistic capacity of bacterial populations from five fruit development stages of ‘Royal Gala’ apples. The re-... -

인터넷은 건강문제의 해결과 극복을 위한 주요 수단으로 부각하였다. 본 연구는 유사한 정신적, 육체적 만성 질환을 경험하는 이들이 온라인 커뮤니티 등의 인터넷을 통해 어떻게 정보를 취득, 공유, 선택하고 나아가 관계를 형성 유지하는가를 살펴 보았다. 또한 정신적 질환과 육체적 질환간의 온라인 정보행위들이 어떻게 정서적, 육체적 코핑을 유도하는가와 두 질환 응답자들 간의 코핑 결과 상의 차이를 검증해 보았다. 연구 결과 두 집단 모두 건강문제에 대한 정보행위들이 활발 하였고 사이버 코핑 긍정적 효과를 갖는 것으로... -
“The Weight Falls on My Shoulders”: Perceptions of Compassion Fatigue Among Israeli Preschool Teachers
Inbar Levkovich, Anat Gada 환태평양유아교육연구학회 Asia-Pacific journal of research in early childhood education 22 Pages
환태평양유아교육연구학회 Asia-Pacific journal of research in early childhood education 2020, Vol.14 No.3 5 91-112 (22 pages)
Compassion fatigue is defined as indirect or secondary trauma that develops among caregivers as a result of their involvement in the trauma state of the individual under their care, to the point that they begin to empathize with and become deeply involved in the other person’s feelings and suffering. The present study evaluated perceptions of compassion fatigue among 15 preschool teachers in Israel by means of qualitative in-depth semi-structured interviews. The study’s findings show that... -
NO gas sensing ability of activated carbon fibers modified by an electron beam for improvement in the surface functional group
Mi-Seon Park, Sangmin Lee, Min-Jung Jung, Hyeong Gi Kim, Young-Seak Lee 한국탄소학회 Carbon Letters 7 Pages
한국탄소학회 Carbon Letters 2016, Vol.20 3 19-25 (7 pages)
Activated carbon fiber (ACF) surfaces are modified using an electron beam under different aqueous solutions to improve the NO gas sensitivity of a gas sensor based on ACFs. The oxygen functional group on the ACF surface is changed, resulting in an increase of the number of non-carbonyl (-C-O-C-) groups from 32.5% for pristine ACFs to 39.53% and 41.75% for ACFs treated with hydrogen peroxide and potassium hydroxide solutions, respectively. We discover that the NO gas sensitivity of the gas sensor... -
Carbon rich fly ash and their nanostructures

한국탄소학회 Carbon Letters 2016, Vol.19 3 23-31 (9 pages)
Carbon rich fly ash was recently reported to have compositions that are ideal for use as a precursor and catalyst for carbon nanotube growth. This fly ash powder is mostly composed of pure carbon, predominantly present as sp2. In this work, the effect of sonication time on the morphology and structural properties of carbon rich fly ash particles is reported. The obtained results show that ultrasound treatment is an effective tool for producing ultrafine particles/fragments with higher porosity,... -

한국탄소학회 Carbon Letters 2015, Vol.16 No.1 10 62-66 (5 pages)
In this study, carbonized fibers were prepared by using acidically cross-linked LDPE fibers. The surface morphologies of the carbonized fibers were observed by SEM. The effects of cross-linking process temperatures were studied using thermal analyses such as DSC and TGA. The melting and heating enthalpy of the fibers decreased as the cross-linking temperature increased. The cross-linked fibers had a carbonization yield of over 50%. From SEM results the highest yield of carbonized LDPE-based... -
Conducting and interface characterization of carbonate-type organic electrolytes containing EMImBF4 as an additive against activated carbon electrode
Mingyeong Kim, Kyungmin Kim and Seok Kim 한국탄소학회 Carbon Letters 6 Pages
한국탄소학회 Carbon Letters 2015, Vol.16 No.1 8 51-56 (6 pages)
Carbonate-type organic electrolytes were prepared using propylene carbonate (PC) and dimethyl carbonate (DMC) as a solvent, quaternary ammonium salts, and by adding different contents of 1-ethyl-3-methyl imidazolium tetrafluoroborate (EMImBF4). Cyclic voltammetry and linear sweep voltammetry were performed to analyze conducting behaviors. The surface characterizations were analyzed by scanning electron microscopy method and X-ray photoelectron spectroscopy. From the experimental results,... -
Preparation of sulfonated reduced graphene oxide by radiationinduced chemical reduction of sulfonated graphene oxide
Chang-Hee Jung, Ji-Hyun Hong, Jin-Mook Jung, In-Tae Hwang, Chan-Hee Jung and Jae-Hak Choi 한국탄소학회 Carbon Letters 4 Pages
한국탄소학회 Carbon Letters 2015, Vol.16 No.1 6 41-44 (4 pages)
We report the preparation of sulfonated reduced graphene oxide (SRGO) by the sulfonation of graphene oxide followed by radiation-induced chemical reduction. Graphene oxide prepared by the well-known modified Hummer's method was sulfonated with the aryl diazonium salt of sulfanilic acid. Sulfonated graphene oxide (SGO) dispersed in ethanol was subsequently reduced by γ-ray irradiation at various absorbed doses to produce SRGO. The results of optical, chemical, and thermal analyses revealed that... -
Influence of ionic liquid additives on the conducting and interfacial properties of organic solvent-based electrolytes against an activated carbon electrode
Kyungmin Kim, Yongju Jung, Seok Kim 한국탄소학회 Carbon Letters 5 Pages
한국탄소학회 Carbon Letters 2014, Vol.15 No.3 5 187-191 (5 pages)
This study reports on the influence of N-butyl-N-methylpyrrolidinium tetrafluoroborate (PYR14BF4) ionic liquid additive on the conducting and interfacial properties of organic solvent based electrolytes against a carbon electrode. We used the mixture of ethylene carbonate/dimethoxyethane (1:1) as an organic solvent electrolyte and tetraethylammonium tetrafluoroborate (TEABF4) as a common salt. Using the PYR14BF ionic liquid as additive produced higher ionic conductivity in the electrolyte and...
