  • Multi-hop cellular networks (MCNs) reduce the transmit power and improve the system performance. Recently, several research studies have been conducted on MCNs. The mobile relay selection scheme is a rising issue in the design of MCNs that achieves these advantages. The conventional opportunistic relaying (OR) is performed on the single factor for maximum signal-to-interference-plus-noise ratio (SINR). In this paper, a comprehensive OR scheme based on Bi-Target is proposed to improve the system throughput and reduce the relay handover by constraining the amount of required bandwidth and SINR. Moreover, the proposed algorithm captures the variability and the mobility that makes it more suitable for dynamic real scenarios. Numerical and simulation results show the superiority of the proposed algorithm in both enhancing the overall performance and reducing the handover.

  • We performed this study to determine the radioprotective effects of Shi-Quan-Dai-Bu-Tang, as a prescription of traditional Oriental medicine, and its major ingredients. The jejunal crypt survival, endogenous spleen colony formation, and apoptosis in jejunal crypt cells were investigated in mice irradiated with high and low dose of ${\gamma}$-rays. The administration of danggui, baishaoyao, rensan, gancao or baifuling before irradiation protected the jejunal crypts (p<0.005). Shoudehuang, danggui, baishaoyao, rensan and huangqui increased the formation of endogenous spleen colony (p<0.05). Chuanxiong, baishaoyao, rensan and baifuling reduced the frequency of radiation-induced apotosis (p<0.05). The results indicated that the extracts of danggui, baishaoyao, rensan and baifuling may have radoprotective effects in mice irradiated with high and low dose of ${\gamma}$-rays. The radioprotective effect of the prescription, Shi-Qaun-Da-Bu-Tang, was not significant.

  • The concept of interfaith harmony is one of the key issues for discussion in this contemporary world. It has multifaceted implications that range from pedagogical realms to global policy making. Here we focus on the basic concepts of interfaith harmony from Sikh and Cao Dai perspectives in order to address their viewpoints in regard to promoting culture of Peace and Understanding. Although these religions are new as compared to the existing living religions of the world, they found their new identity in the history of world religions for their unique concepts of interfaith harmony. In this article, the concept of interfaith harmony has been analyzed from two perspectives such as theological and socio-historical. For a systematic understanding of the subject matter, it has been categorized into three subpoints; unity of God, unity of religions and unity of humanity. Methodologically, the qualitative methodological framework of the proposed research is descriptive in nature. Thus, the present research has been primarily conducted by using secondary sources, although the crucial information is collected from primary sources such as the sacred texts of Sikhism and Caodaism. Since this study is done considering the social, political and religious contexts of India and Vietnam, it can contribute to the understanding of the nature of interfaith harmony in South and South-East Asia.

  • The 1080 epiphytic bacteria obtained from 370 samples of pome and stone fruits including apple, pear, peach, grape, apricot and Chinese quince were screened for antagonistic activity against postharvest pathogens, Penicillium expansum, Alternaria alternata and Botrytis cinerea. Among tested antagonistic bacteria, eight bacterial isolates inhibited mycelial growth of the postharvest pathogens and were identified as Bacillus amyloliquefaciens (three strains), B. megaterium, B. subtilis var. gladioli, B. licheniformis, B. pumilus and Serratia marcescens based on biochemical characteristics and utility of carbon and nitrogen compounds (Biolog system). Eight carbohydrates were evaluated for their effect on mycelial growth and germination of the postharvest pathogen, P. expansum to select nutrients for enhancing bio-control efficacy. The growth of four selected antagonists, B. amyloliquefaciens P43-2, B. amyloliquefaciens A71-2, B. licheniformis P94-1, and S. marcescens P76-9 were also tested. As a result, 1% glucose (w/v) strongly stimulated growth of the antagonists, suppressed mycelial growth of the postharvest pathogen, and had a little comparatively stimulatory effect on germination of the the postharvest pathogen. It was confirmed that the addition of 1% glucose (w/v) greatly enhanced biocontrol effect of B. amyloliquefaciens P43-2, B. licheniformis P94-1, and S. marcescens P76-9. Application of B. amyloliquefaciens P43-2, B. licheniformis P94-1, and S. marcescens P76-9 with the addition of 1% glucose (w/v) increased the control efficacy up to 48%, 46%, 14% compared with those of the antagonists without glucose, respectively. When the antagonists were applied to control postharvest disease caused by P. expansum in apple wounds, the population of B. amyloliquefaciens P43-2 and B. licheniformis P94-1 increased until 4 days after inoculation (DAI) of the antagonists and then decreased from 10 DAI. Meanwhile the population of S. marcescens P76-9 decreased at early stage (4 DAI), but increased from 7 DAI, and finally maintained constantly until 10 DAI in apple wounds.

  • Objectives : The purpose of this study is to find out herb-pair prototype composed of Aconiti Radix(烏頭) or Aconiti Lateralis Preparata Radix(附子) written in ancient chinese medical classics. Methods : To search usages of Aconiti Radix and/or Aconiti Lateralis Preparata Radix, we have investigated the classics of herb and prescription such as "Fifty-two kinds of Diseases"("五十二病方"),"WuWeiHanDaiYiJian" ("武威漢代醫簡"),"Treatise on Febrile Caused by Cold"("傷寒論"),"Synopsis of Prescriptions of The Golden Chamber"("金匱要略"). Results : There were three herb pairs of Aconiti Radix and/or Aconiti Lateralis Preparata Radix in "Fifty-two kinds of Diseases", four herb pairs of it in "WuWeiHanDaiYiJian", eight herb pairs of it in "Treatise on Febrile Caused by Cold", and five herb pairs of it in "Synopsis of Prescriptions of The Golden Chamber". Conclusions : 1. Aconiti Radix herb-pairs written in ancient chinese medical classics are as follows ; Cinnamomi Cortex(桂), Arsenopyritum(礜) and Veratri Nigri Rhizoma et Radix(藜蘆). Zanthoxyli Fructus(蜀椒), Aconiti Lateralis Preparata Radix(附子), honey(蜜) and Asari Radix(細辛). 2. Aconiti Lateralis Preparata Radix(附子) herb-pairs written in ancient chinese medical classics are as follows ; Zanthoxyli Fructus(蜀椒), Paeonia Radx(芍藥), Ephedrae Herba(麻黃), Zingiberis Rhizoma(乾薑), Zingiberis Rhizoma(乾薑)-Allii Radix(葱白), Cinnamomi Cortex(桂), Atractylodis Rhizoma White(白朮), Poria(茯苓), Atractylodis Rhizoma White(白朮)-Poria(茯苓) and Gentianae Macrophyllae Radix(秦艽), Coisis semen(薏苡仁), Pinelliae Rhizoma(半夏). 3. In "Fifty-two kinds of Diseases"only Aconiti Radix was used and in "Treatise on Febrile Caused by Cold"only Aconiti Lateralis Preparata Radix was used, but in "WuWeiHanDaiYiJian"and "Synopsis of Prescriptions of The Golden Chamber"both herbs were used. 4. Method for reducing toxicity of Aconiti Radix and Aconiti Lateralis Preparata Radix was found in "Treatise on Febrile Caused by Cold"and "Synopsis of Prescriptions of The Golden Chamber".
