Hydroxyl radical (OH radical) is the most harmful free radical amongst the Reactive Oxygen Species (ROS) responsible for numerous diseases of DNA damage like mutagenesis, carcinogenesis and ageing. Therefore, it is important to find a suitable scavenger for OH radical. In the present contribution, we aim to investigate the ability of pristine armchair-SWCNT and B/N/P-doped armchair-SWCNT to scavenge OH radicals using DFT calculations. The calculations reveal that the B/Pdoped armchair-SWCNTs can act as a better scavenger for OH radical compared to pristine armchair-SWCNT but N-doped armchair-SWCNT does not act as a better scavenger for OH radical compared to pristine armchair-SWCNT. Furthermore, the developed scavenger is examined in terms of large-scale availability, biocompatibility, conductivity, stability and reactivity. For both in vivo and in vitro studies, the work is found to useful for enhancing SWCNT as a free radical scavenger.

본 논문은 非目的语의 환경에서 베트남의 한어학습자들을 대상으로 하여, 지필 테스트(paperand- pencil test) 방식으로 그들의 한자 형방 인식의 발전 과정에 대한 연구를 진행하였다. 그 결과는 다음과 같다. 베트남 한어학습자들이 초·중급 단계에 있을 때 여전히 스스로 형방을 인식하지 못하였으나 고급 단계에 진입한 후 형방을 비교적 스스로 인식할 수 있게 되었다. 체계적인 한자 이론 지식 교육은 학습자들이 한자 형성자의 형방에 대한 인식과 그 발전에 도움이 되었다. 중국 유학생들과 비교 연구를 통하여 본 논문은 서로 다른 언어 학습 환경에서 학습자들이 형성자들을 인식하는 데 있어서도 서로 다른 발전 양상이 있음을 발견할 수 있었다.

許愼은 『說文解字』라는 중국 최고의 字書를 편찬하면서 部首라는 개념을 만들었다. 540개의 部首를 세워 모든 漢字를 각 部首 밑에 귀속시켜 체계 없이 흩어져 있던 漢字를 정리하고 검색의 편리를 제공하였다. 그는 “分別部居, 不相襍廁.”(부수로 분별하여 서로 어지럽게 섞이지 않게 한다.)라는 말로 部首 건립의 취지와 목적을 언급하였다. 그러나 『說文解字』 540개의 部首를 조사해 보면 部首만 세워놓고 이 部首에 귀속된 문자가 하나도 없는 無屬部字 部首가 36개나 되며, 屬部字가 단 1개뿐인 部首도 156개나 된다고 한다. 귀속된 문자가 없거나 극소수인 部首가 과연 540개라는 部首의 숫자를 채우는 역할 이외에 部首로서의 어떠한 기능을 하는 지, 꼭 필요한 것인지에 대해 의문을 품게 된다. 許愼은 왜 이들을 독립된 部首로 세워야만 했는지, 이보다 좀 더 합리적인 다른 방법은 없었는지 라는 의문에 대해 미력이나마 의견을 보태보려고 한다. 우선 36개의 無屬部字를 대상으로 『說文解字』 部首 건립의 취지와 목적, 全書에 나타난 部首 배치의 예, 상호 간의 관계, 그리고 小篆 字形을 분석하여 他部首와의 통합이 가능한 지 여부를 타진해 보고자 한다.

Abundant cultural information is included in the items for names, marriage and family, Zi or Hao, and the description of women in Shuowen, a noted Chinese dictionary. The research and analysis on it will help us understand the customs, morals, social systems, tastes and habits of thought in ancient China, and comprehend the basic characteristics and spirits of Chinese culture.

The paper carries out a systematic survey on the origins, evolution, formation module of 201 radicals of Chinese characters by means of database analysis method. On the basis of the above investigation, the research probes into the relation between 201 radicals and HSK 2905 from the aspects of Ziwei (overlapping percentage), character-formation frequency, positions and functions. With the help of the psychological theory, the methods of learning radicals are provided for reference.

In this paper, we take the 201 radicals as the object of our study, by way of using statistical and analytical methods of database, comprehensively and systematically researching and analyzing the origin, evolution, forms of structure of these radicals. Based on this, study on the multiple relationships of the 201 radicals and HSK2905 Chinese Characters just like the frequency, position and function of these radicals when they are used for constructing Chinese Characters.

The conventional development of multi-component electrodes is based on the researcher's experience and is based on trial and error. Therefore, there is a need for a scientific method to reduce the time and economic losses thereof and systematize the mixing of electrode components. In this study, we use design of mixture experiments (DOME)- in particular a simplex lattice design with Design Expert◯R program- to attempt to find an optimum mixing ratio for a three-component electrode for the high RNO degradation; RNO is an indictor of OH radical formation. The experiment included 12 experimental points with 2 center replicates for 3 different independent variables (with the molar ratio of Ru, Ti, Ir). As the Prob > F value of the ‘Quadratic’ model is 0.0026, the secondary model was found to be suitable. Applying the molar ratio of the electrode components to the corrected response model results is an RNO removal efficiency (%) = 59.89 × [Ru] + 9.78 × [Ti] + 67.03 × [Ir] + 66.38 × [Ru] × [Ir] + 132.86 × [Ti] × [Ir]. The R2 value of the equation is 0.9374 after the error term is excluded. The optimized formulation of the ternary electrode for an high RNO degradation was acquired when the molar ratio of Ru 0.100, Ti 0.200, Ir 0.700 (desirability d value, 1).

The purpose of this paper is to explore the relationship between Calvin and Anabaptist radicals in the sixteenth century This study first traces the relations of Calvin and Anabaptists from historical perspective, and then examines from theological perspective Schleitheim Confession(1527), which is an early Anabaptists’ articles of faith, and Calvin’s Brief Instruction Against the Errors of the Common Sect of the Anabaptists(1544), which is Calvin’s refutation against Schleitheim Confession. In the sixteenth-century reformation movements, Calvin on the one hand should fight against Roman Catholicism, and on the other hand have to stand against Anabaptist radicals. Calvin cries for reform against Roman Church’s ecclesia deformata, at the same time he raises his voice against Anabaptist’s sectarian errors pursuing ecclesia perfecta. This study discloses what Calvin and Anabaptists argue, and what theological points of dispute between them are. In particular, it analyzes their differences from three significant topics, baptism, church, and state.
