A Review of Design Considerations and Representation of Sustainable Tall Building
Kim, Hyeong-Il,Shin, Sung-Woo Sustainable Building Research Center 2011 International journal of sustainable building tech Vol.2 No.4
The purpose of this paper is to introduce design considerations for the super tall building especially those related with sustainable design methodology and the topic presented in the SB11 Helsinki World Sustainable Building Conference by Hyeong-il Kim. The design of tall buildings should take into consideration of environmental impact and economic benefits from sustainable approaches to ensure low energy consumption and $CO_2$ emissions. In the paper, author tried to identify key issues related to sustainable building technology and emphasis the role of the sustainability in tall building design. The study also provides analytical survey of the significance of adaptable use of sustainable solutions that demonstrate use of renewable energy resources, and respond to climatic conditions with energy conscious design principles including form, orientation and materiality of the buildings on the current practice.
수령독재 하에서 권력과 이권을 둘러싼 갈등 동학 그리고 장성택 숙청
박형중 ( Hyeong Jung Park ),최대석 ( Dae Seok Choe ),김학성 ( Hank Sung Kim ),박영자 ( Young Ja Park ),장인숙 ( In Suk Jang ) 북한연구학회 2014 北韓硏究學會報 Vol.18 No.1
수령독재 하에서는 수령 지위를 차지하고자 하는 권력 투쟁은 존재하지 않는다. 그러나 수평적으로 주요 기관과 엘리트 개인의 권력과 이권의 지분을 확대하기 위한 경쟁이 존재한다. 이러한 경쟁은 수령에 대한 ‘충성경쟁’이라는 외피를 갖는다. 권력 세습 기간 동안 이러한 경쟁이 현저히 증가한다. 권력 세습은 수령독재가 기반하는 통치연합을 재편성하는 과정이기 때문이다. 김정일에서 김정은으로의 권력 세습 과정에서 기관과 엘리트 사이에 권력 및 이권 관련경쟁에서 두 가지가 두드러지게 나타났다. 그 하나는 권력 세습 과정에서의 주도적 세력이 되고자 하는 경쟁 즉 후견권을 둘러싼 경쟁이다. 그 다른 하나는 기관별로 권력과 이권의 지분을 확대하기 위한 경쟁이다. 장성택은 이 두 가지 경쟁에서 모두 주역이었다. 그의 숙청도 이와 관련되어 있었다. Under the Suryong dictatorship, by definition, there is no political completion for Suryong`s status. There are, however, horizontal competitions to expand power and interest carried out by major power organizations and elites. Apparently they are loyalty competition devoted to the Suryong. During the power succession, as the ruling coalition is reconstructed, they intensify themselves. Two features have been pronounced during the hereditary succession from Kim Jong-il to Kim Jong-un in regard to competition for power and interest among power organizations and elites: the one is the competition for regency, i.e. to advance oneself as the dominant force in the promotion of the power succession; the other is the competition for increasing share of power and interest by power organizations and elites. Jang Sung-taek has stood in the center of these two competitions and he was purge thereof.

Neuroprotective effects of Moringa oleifera leaf extracts

This study was carried out to evaluation the neuroprotective effects of Moringa oleifera leaf. The polyphenols myricetin and kaempferol were detected in M. oleifera leaf at 5.44 and 1,157.13 mg/100 g, respectively. M. oleifera leaf ethanol extract (MOLE) reduced oxidative stress (%) more than vitamin C did (90.26%) at 100 and 200 μg/mL (p<0.05). MOLE increased cell viability (%) (p<0.05) and similarly to vitamin C (88.36%). Additionally, the lactate dehydrogenase (LDH) release into the medium (%) induced by ascorbic acid (vitamin C) was comparable to that of MOLE at 100 and 200 μg/mL (p>0.05). The antioxidant activities of M. oleifera leaf water extract (MOLW) and MOLE were measured. MOLE showed higher 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) radical scavenging (%) and malondialdehyde inhibition (%) than MOLW did (p<0.05). In conclusion, M. oleifera leaf extracts, especially MOLE could be potential natural neuroprotective agents to substitute synthetic chemicals.
Improvement of Glaze Hardness in Commercial Bone China
Kim, Hyeong-Jun,Han, Yoon Soo,Kim, Dong-Hwan,Kim, Da-Mi,Choi, Jae-Ho,Lee, Sung-Min,Kim, Yoojin,Kim, Hyung-Tae The Korean Ceramic Society 2015 한국세라믹학회지 Vol.52 No.6
In order to improve the hardness of commercial bone china, we attempted to control the glost firing temperature and apply a chemical strengthening process. When the glost firing time was longer or its temperature was higher than normal conditions, the hardness was improved by approximately 5%. The chemical strengthening process also enhanced the hardness of the glaze by more than 13% compared with bone china. It is believed that the enhancement of the hardness of the glaze was related to the development of residual compressive stress in the glaze due to 1) the increase in the calcium phosphate phase in the interface layer between the body and the glaze after firing, and 2) the increase of the $K^+$ concentration on the glaze surface during the chemical strengthening process.
