Korean ginseng and mountain ginseng （Panax ginseng CA Meyer） are important traditional herbal plants whose ginsenosides are generally accepted as serving to improve sexual functions, such as penile erection. We investigated the effects of tissue-cultured mountain ginseng extract （TMGE） on male patients with erectile dysfunction （ED）. A double-blind, placebo-controlled study was conducted with 143 patients experiencing ED. Over the course of 8 weeks, one group took 1 000 mg of TMGE twice a day, and the other group took 1 000 mg of placebo twice a day. The effects of the TMGE and the placebo were analyzed using the Korean version of the International Index of Erectile Function （IIEF） questionnaire. A total of 86 patients completed 8 weeks of treatment. The scores on the five domains of the IIEF after medication were significantly higher than the baseline scores in the group treated with TMGE （P 〈 0.05）, whereas no significant improvement was observed in the placebo group （P 〉 0.05）. Erectile function and overall satisfaction scores after medication were significantly higher in the TMGE group than in the placebo group （P 〈 0.05）. Erectile function of patients in the TMGE-treated group significantly improved, suggesting that TMGE could be utilized for improving erectile function in male patients.

生物工程学报 2008年第5期24卷 711-716页

作者： Hosakatte Niranjana Murthy eun joo hahn Kee Yoeup Paek Research Center for the Development of Advanced Horticultural Technology Chungbuk National University Cheongju 361-763 South Korea Department of Botany Karnatak University Dharwad 580003 India

Plants are a rich source of valuable secondary metabolites and in the recent years plant cell, tissue and organ cultures have been developed as an important alternative sources for the production of these compounds. Adventitious roots have been successfully induced in many plant species and cultured for the production of high value secondary metabolites of pharmaceutical, nutraceutical and industrial importance. Adoption of elicitation methods have shown improved synthesis of secondary metabolites in adventitious root cultures. Development of large-scale culture methods using bioreactors has opened up feasibilities of production of secondary metabolites at the industrial levels. In the present review we summarize the progress made in recent past in the area of adventitious root cultures for the production of secondary metabolites.

Spatial phase-shifting interferometry with compensation of geometric errors based on genetic algorithm(Invited Paper)

引用

Chinese Optics Letters 2009年第12期7卷 1113-1116页

作者： joonku hahn Hwi Kim Yongjun Lim eun-Hee Kim Byoungho Lee School of Electrical Engineering Seoul National University

We propose a novel spatial phase-shifting interferometry that exploits a genetic algorithm to compensate for geometric errors. Spatial phase-shifting interferometry is more suitable for measuring objects with properties that change rapidly in time than the temporal phase-shifting interferometry. However, it is more susceptible to the geometric errors since the positions at which interferograms are collected are different. In this letter, we propose a spatial phase-shifting interferometry with separate paths for object and reference waves. Also, the object wave estimate is parameterized in terms of geometric errors, and the error is compensated by using a genetic algorithm.

Development of 3D bicontinuous metal-intermetallic composites through subsequent alloying process after liquid metal dealloying

引用

Journal of Magnesium and Alloys 2023年第11期11卷 4274-4281页

作者： Jee eun Jang Jihye Seong Soo-Hyun joo Sung Hyuk Park School of Materials Science and Engineering Kyungpook National UniversityDaegu 41566Republic of Korea Department of Materials Science and Engineering Dankook UniversityCheonan 31116Republic of Korea

This study presents a novel process for the fabrication of metal-intermetallic composites with a 3D bicontinuous structure, achieved through a combination of liquid metal dealloying(LMD) and subsequent alloying. Initially, porous Ti structures are produced using the LMD process, followed by immersion in a molten Mg-3Al(wt%) metal. Due to the higher thermodynamic miscibility of Al with Ti compared to Mg, the concentration of Al in the Ti matrix increases as the immersion time increases. This results in a sequential phase transition within the Ti matrix: α-Ti → Ti_(3)Al → Ti Al. The phase transition considerably affects the hardness and strength of the composite material,with the Mg-Ti_(3)Al-Ti Al composite exhibiting a maximum hardness nearly twice as high as that of the conventional Mg-Ti composite. This innovative process holds potential for the development of various bicontinuous metal-intermetallic composites.
