This paper is considering on investigation of the single nature theory of Wangyangming. Most of all, His single nature's theory is the results of critical reflections on the nature theory suggested by Zhuxi's learning. His theory has two unique characteristics. First, in contrast to Zhuxi's arguments, WangYangMing emphasize the single 'QiZhizhiXing(氣質之性)' which unify 'XingjiQi(性卽氣)' with Gaozi(告子)'s 'ShengzhiweiXing(生之謂性)' theory, and present view that 'nature is only one'. Second, He regards The Four Virtue(四德) and The Four Sprout(四端) as 'revealed virtues(表德)', defines them as 'already produced(已發)' virtues at the same time. Through this course, he tries to dismantle various nature and virtues which were constructed based on the criterion of 'XingerShang(形而上)' and 'XingerXia(形而下)'. The reason why he unify all the nature theory which Zhuxi had suggested as one nature's category, is not based on the theocratical interest but on the practical interest. In other words, he tries to provide the more practical methodology which each learner can directly embody and cultivate his own nature in his or her daily life.

The purpose of this study is to propose remedial devices through the analysis on the operation status of nature trails in the nine National Parks in Korea. To accomplish these goals, the field survey for the nature trail facilities and their nature environmental conditions and a questionnaire survey also had been done, and 1,102 samples have been collected. Nature trails are usually located where the visitors re concentrated for a certain season or year-round, and ease of the visits guaranteed. However, since most of trails are located along the valley, the courses have disadvantage of passing in a single trail. Also, many trails are using former tracking courses, and the environmental conditions are not satisfactory due to the damages incurred by the visitors. Since nature trails are still on the introductory stage, basic tactics such as the design of courses, construction methods, management skills needs further improvements. As the Natural Parks Act does not have any clear definition of nature trails, it invokes the definition of tracking course instead, which in turn hinders the development of the nature trails. The nature trail system was just introduced to Korean National Parks and a pioneer in the Korea. Therefore, when provincial and urban recreational parks wish to introduce the environmental education programs within each park system, nature trails in national parks can be performed as a role model. Further improvements should be made within the such fields as preliminary natural ecological survey, lacks of professional designers for the facilities, lacks of interpreter and interpretation within nature trails.

Detailed information about the structural nature of three-coordinate borons in ${\beta}-BaB_2O_4$ is obtained through $^{11}B$ MAS NMR and $^{11}B$ single-crystal NMR. The three-coordinate $BO_3$ of the two borons B(1) and B(2) in ${\beta}-BaB_2O_4$ were distinguished. The spin-lattice relaxation time in the laboratory frame $T_1$ for B(1) and B(2) slowly decreases with increasing temperature, whereas the spin-lattice relaxation time in the rotating frame $T_{1{\rho}}$ for B(1) and B(2), which differs from $T_1$, is nearly constant. The B(1) and B(2) of the two types were distinguished by $^{11}B$ MAS NMR and $^{11}B$ single-crystal NMR.

The traditional theories of games are based on an assumption that the payoffs have a single dimension. In reality, any alternative is likely to imply more than one payoff. This paper deals with the game against nature with vector payoffs. The purpose of this paper is to develop methods for finding the practical optimal strategy in the game against nature with vector payoffs. Under the assumption that a prior probability over the stats of nature is given, this paper shows that a practical optimal strategy in this game can be obtained by applying a entropy method in order to assess the payoff weight and by employing the concept of compromise solutions in order to reduce the non-dominated solutions. When subjective payoff weights are unknown as well as known, these methods can be used. A numerical example is given.

Single-crystal Ni-rich NCM is a material that has drawn attention in the field of lithium-ion batteries due to its high energy density and long cycle life. In this study, we investigated the properties of single-crystal NCM 811 and its potential for use in lithium-ion batteries. High-quality single crystals of NCM 811 were successfully synthesized by crystal growth via a flux method. The single-crystal nature of the samples was confirmed through detailed characterization techniques, such as scanning electron microscopy and x-ray diffraction with Rietveld refinement. The crystal structure and electrochemical performances of the single-crystal NCM 811 were analyzed and compared to its poly-crystal counterpart. The results indicated that single-crystal NCM 811 had electrochemical performance and thermal stability superior to poly-crystalline NCM 811, making it a suitable candidate for high-performance batteries. The findings of this study contribute to a better understanding of the characteristics and potential of single-crystal NCM 811 for lithium-ion batteries.

We report for the first time the synthesis of niobium dioxide nanowires on a sapphire substrate by chemical vapor transport method. We identified single crystalline nature of as-synthesized nanowires by scanning electron microscopy and transmission electron microscopy. Niobium dioxide nanowires with their large surface-to-volume ratio and high activities can be employed for electrochemical catalysts and immunosensors. The Raman spectrum of niobium dioxide nanowires also confirmed their identity.

Both in terms of frequency and importance, sympathy is one of the most central themes that Mary Shelley's Frankenstein (1818) delves into. While not a few critics have written on the subject, one crucially important aspect has been overlooked in the previous discussions of sympathy in Frankenstein: Shelley's critical intervention in the term's long lasting association with the notion of one body from a single origin. Focusing on the novel's central theme of sympathy, my paper addresses this oversight in the existing Frankenstein scholarship. I argue that Shelley's main agenda regarding sympathy in the novel is to problematize the logic of self-reproduction implicit in the notion of sympathy as an essentially familial tie. The reading of the novel as a warning against human violation of nature has been prevalent both in academia and popular culture. Nonetheless, in terms of sympathy, this paper offers an alternative reading in which the novel questions, not valorizes, the naturalization of nature. Far from valorizing the inviolable sacredness of nature, I argue, Frankenstein is a literary project attempting to disassociate sympathy from the natural bond that one is born into, and instead, re-associate it with fellowship as a second-nature to be continuously reinvented and reeducated.

The spectral properties, namely the circular dichroism, electric absorption and luminescence properties, of Λ- and Δ-[Ru(II)(1,10-phenanthroline)2benzodipyrido[b:3,2-h:2',3'-j]phenazine]2+ ([Ru(phen)2BDPPZ]2+) in the presence and absence of single stranded poly(dA) and poly(dT) were compared in this work. In the presence of single stranded DNAs, hypochromism in the absorption spectrum and significant changes in the circular dichroism spectrum in the ligand absorption band were apparent, indicating the strong interaction of the [Ru(phen)2BDPPZ]2+ complex with the single stranded DNAs. The luminescence intensity of the Ru(II) complex decreased stoichiometrically with increasing concentrations of the single stranded DNAs. All of these spectral changes were independent of the configuration of the Ru(II) complex and the nature of the DNA bases. Therefore, it is conceivable that both enantiomers of the [Ru(phen)2BDPPZ]2+ complex interact electrostatically with the negatively charged phosphate groups of DNA. However, the spectral properties of [Ru(II)(1,10-phenanthroline)3]2+ were not altered even in the presence of single stranded DNAs. Therefore, the size of the ligand involved in the interaction of the metal complex with the phosphate group of DNA may play an important role, even when the nature of the interaction is electrostatic.

This study attempted an eco-ethical approach to the sporting body, focusing on Toegye's Gyeong. A causes for the conflict between man and nature is a wrong view of nature derived from human desire. Toegye thought that the problem of desire could be overcome through Gyeong. Eco-ethical approaches of Toegye's gyeong thought are possible for the following reasons: First, because Toegye's gyeong is completed in nature. Second, because Toegye's gyeong emphasize human responsibility (consideration) for nature. Third, because gyeong is related to the ability to practice morality. Meanwhile, Toegye understood 'preserving the body well' as self-preservation and at the same time, as the meaning of a natural principle of following the laws of nature. From this perspective, the sporting body has meanings of physical fitness and mental health and at the same time, an aspect of ecological values of understanding man and nature as a single network and following the order of nature. Acquisition of Gyeong through the sporting body suggests the practice of 'gyeongsin (respect for the body)' and 'hwalgyeong (preservation of the ecological environment).' When human beings do physical exercise with nature, they proceed to the stage of building up the virtue of yosan yosu (finding happiness in mountains and water) through nature preserving the ecological environment (hwalgyeong) beyond staying at the stage of gyeongsin.

This study is an investigation regarding the understanding of the nature of science among pre-service science teachers majoring in science education. We interviewed 22 senior students in science education who finished their internship courses. Students were interviewed individually for approximately 20 minutes each. Data from semi-structured interview were audio-recorded and transcribed for the analysis. Findings indicated that participants held more complete understanding of the nature of scientific knowledge than the nature of scientific enterprise. Their understandings of the nature of scientific method was that hypothetical-deductive method is more scientific than descriptive-narrative method and there is a single stepwise scientific method to solve problems. These results showed that they have a narrow view of the nature of science. Thus, teacher education programs need to integrate the understanding of the nature of science throughout.
