The pitch-based activated carbons were prepared with KOH/KMnO4 as a multiple function activation agent to increase the specific capacitance of a supercapacitor electrode active material. And the porous structure and electrochemical properties of activated carbon were analyzed on varying amounts of KMnO4. KMnO4 was decomposed into K2O, MnO, and O2 at the activation temperature of KOH, and MnO was introduced to activated carbon. K2O/ O2 reacts with a surrounding pitch to generate micropores and forms a pathway that exposes MnO to the outside. It also affects to the specific surface area of activated carbon like KOH chemical activation. The enhanced specific surface area and introduced MnO in activated carbon led to a 28.9% increase in specific capacitance.

성년의 남성은 노화가 진행됨에 따라 혈중 testosterone이 감소 되면서 갱년기증상을 나타낸다. 랫드(Ratus norvegicus)는 생식 시스템이 인간과 매우 유사하여 실험 모델로 그 활용 빈도가 높은 동물이다. 본 연구에서는 남성갱년기 동물모델 확립을 위해 22주령과 50주령 랫드의 생식 기관 무게, testosterone 을 포함하는 호르몬 및 생화학적 변화에 대한 비교 연구를 진행하였다. 그 결과 22주령에 비해 50주령의 체중 및 생식기관 무게가 높게 측정 되었다. 혈중 dihydrotestosterone(DHT)는 50주령에 비해 22주령에 서 높게 측정되었다. Aspartate aminotransferasel(AST), alanine aminotransferase(ALP), total protein (TP), triglyceride(TG)와 total cholesterol(TC)은 50주령 랫드 그룹에서 유의적으로 증가되었다. 또한, 혈중 luteinizing hormone(LH)는 50주령 랫드 그룹에서 현저히 감소되었으나, follicle stimulating hormone(FSH)는 두 그룹간 차이를 나타내지 않았다. 본 연구의 결과들을 종합할 때 22주령과 50주령 랫드의 비교 실험은 남성갱년기 동물모델 시스템으로 적용 가능할 것으로 판단되며 보다 확고한 남성갱년기 전용 동물모델 시스템 확립을 위해서는 생육기간에 따른 다양한 인자들에 대한 지속적인 연구가 진행되어야 할 것으로 판단된다.

The online game market has rapidly increased worldwide, especially in China. In 2012, the world game market equaled 111.7 billion. Many game companies compete by launching new online games in various genres. In 2010, Activision Blizzard reported that the World of Warcraft (WOW) is the world’s most popular online game. Chinese gamers constitute more than half of WOW’s 10 million users. Korea is the second largest gaming market. Thus many foreign game companies target Korea and China, in competition with domestic game companies. The purposes are 1) to understand the role of country of origin and /or brand image in game consumer behavior, 2) to find out the difference of game evaluation between game users in China and Korea, and 3) to draw strategic implication game marketers. Consumers expect products from advanced countries to provide superior performance, so they often look to country of origin in evaluating products. Recently, consumers have looked to brand image as another key element in product evaluation. In this research, we study whether gamers evaluate games on the basis of country of origin and/or brand image. In this paper, we add to the gaming research and suggest that the online game market has three dimensions. First, online games are products. Second, online games are service. Last, online games are entertainment. Data collection resulted in 355 usable responses from online game (LOL) users in Korea(166) and China(189). We conduct factor analysis and reliability analysis to check reliability and validity. Country of Origin is the key element for product evaluation of utilitarian goods but it doesn’t have significant effect on product evaluation of hedonic products which mainly provide sensual pleasure, fantasy, and fun to customers such as luxury goods or online game (Dhar & Wertenbroch, 2000).

Background : This study was development of moisture tolerance and high-yielding Rehmannia glutinosa cultivar. Methods and Results : Segang is developed by the medicinal crop breeding team of National Institute of Horticulture and Herbal Science(NIHHS), Rural Development Administration(RDA), during the period from 2005 to 2015. The reproduction of Rehmannia glutinosa has been accomplished mainly by vegetative propagation with its seedlings have many variants. The cultivar was selected from seedling of Jihwang 1(check variety). The plant type of Segang is some rising from ground. Regional yield trials conducted at three site from 2014 to 2015. The root yield of Segang was 21.1ton per hectare, which was increased 12% compared with Jihwang 1. Also, Segang has higher catalpol content and dried root ratio compared with Jihwang 1. Conclusion : Segang is a moisture tolerance and high-yielding Rehmannia glutinosa cultivar.
