This study examined the perception of gifted teachers toward 'conception of creativity personality education,' 'methodology of creativity personality education,' and 'support of creativity personality education' in the future gifted education. As a result, gifted teachers conceptualized creativity personality education as education to foster creative social capitals(social + moral leaders), which showed movement from gifted education focused on cognitive development into future-developmental orientation. Gifted teachers mentioned education to foster social sensitivity, creativity, and leadership as methodology of creativity personality education. More specifically, they recommended inductive curriculum in learning and teaching in order to encourage domain-specific giftedness. As pointing not to separate creativity personality education for gifted from a formal education but to deploy with conjunction with it, gifted teachers mentioned the social recognition for creativity personality education and the development of teacher's professionalism and educational programs.

Many prefabricated concrete frame joints have been proposed, and most of them showed good seismic performance. However, there are still some limitations in the proposed fabricated joints. For example, for prefabricated prestressed concrete joints, prefabricated beams and prefabricated columns are assembled as a whole by the pre-stressed steel bar and steel strand in the beams, which brings some troubles to the construction, and the reinforcement in the core area of the joints is complex, and the mechanical mechanism is not clear. Based on the current research results, a new type of fabricated joint of prestressed concrete beams and confined concrete columns is proposed. To study the seismic performance of the joint, the quasi-static test is carried out. The test results show that the nodes exhibit good ductility and energy dissipation. According to the experimental fitting method and the "fixed point pointing" law, the resilience model of this kind of nodes is established, and compared with the experimental results, the two agree well, which can provides a certain reference for elasto-plastic seismic response analysis of this type of structure. Besides, based on the analysis of the factors affecting the shear capacity of the node core area, the formula of shear capacity of the core area of the node is proposed, and the theoretical values of the formula are consistent with the experimental value.

The NMR shift arising from the electron angular momentum and the electron spin dipolar-nuclear spin angular momentum interaction has been examined for a $3d_1$ system in a strong octahedral crystal field when the threefold axis is chosen as the quantization axis. To investigate the NMR shift in this situation, first, we have extended the evaluation of the hyperfine integrals to any pairs of 3d orbitals adopting a general method which is applicable to a general vector R, pointing in arbitrary direction in space. Secondly, a general expression using a nonmultipole technique is derived for the NMR shift resulting from the electron angular momentum and the electron spin dipolar-nuclear spin angular momentum interactions. From this expression all the multipolar terms are determined. ${\Delta}B/B$ for the $3d_1$ system in this case is compared with that for the 3d1 system when the z axis is chosen as the quantization axis. When we choose the threefold axis as the quantization axis, it is found that along the , and axes, ${\Delta}B/B$ values are significantly different from each other and along the , <-1-1-1>, <-11-1>, , <-1-11>, , and <-111> axes, ${\Delta}B/B$ values are however the same. We also find that the 1/R7 term contributes dominantly to the NMR shift for all values of R. When 1/$R^5$ term is included, there is good agreement between the exact solution and the multipolar terms when $R\; {\leqslant}\;0.35\;nm.$.

This paper describes differences of performance when the orbit attitude model is applied to the respective images obtained from two different types of satellite. The one is Spot that rotates its pointing mirror and the other is Kompsat-2 that rotates its whole body when they obtain imagery for target. Our research scope is limited to the orbit-attitude model only as its good performance was proved in prior investigation. Model performances between two images were compared with sensor model accuracy and 3D coordinates calculation. The results show performances of the orbit-attitude model for each image type were different. For Spot imagery, the model required attitude angle to be included as adjustment parameters. For Kompsat-2 imagery, the model required high-order parameter for adjustment. This implies that satellite sensor model may be applied differently in accordance with platform's attitude control scheme and accuracy. Understanding of this information can be a base for improvement and development of model and application for new satellite images.

Korean society is a mixed risk society in terms of risk and distrust. This is because the risks and disasters of the farming and industrial societies, the modern and the information society, exist simultaneously in the present time. Ulrich Beck's point that the endless development of science and technology to acquire economic wealth is simultaneously entering a risk society is providing us with many implications. In this paper, we reviewed the Ulrich Beck's "reflexive modernization" theory in the late 20th century, pointing to the rise of a risk society as a result of the evolution of new modernization. This is because the "reflexive modernization" can be a direction in which we can reflect our wrong past from a human-centered perspective and design a desirable future. In this sense, it is important to present ways to overcome the dangerous society through the reinterpretation of Ulrich Beck, who advocated the modernization of reflectively. In order to overcome the future risks that the fourth industrial revolution will bring, we must provide direction for the government's security policies and public security consciousness.

This study was started from a critical mind for the construction records management in South Korea and examined the state of the construction records management system of the Korea Rail Network Authority which is constructing the biggest Express Railway Construction of National Project in Korea. The Methodology of this study is based on the functional requirement of the Records Management International Standard, ISO 15489, which standardized the record management process in the cases of Record Capture, Declaration, Classification, Storage, Access, Tracking and Disposition. In regard to the functional requirements from Capture to Disposition, each level(title) consists of 3 to 4 items, for a total of 22 principles in all. The estimation was created for each of the 22 categories using 4 levels: observance, partial observance, insufficiency and non observance. And pointing out the problem, suggesting the improvements for the Korea Rail Network Authority and structural improvements according to the KS X ISO 15489 principles.

The films of Apichatpong Weerasethakul and Tsai Ming Liang expose one of the main features of modern Asian cinema: corporality. In their films, the various emotions of characters are expressed and exchanged through the body, not the language, so their film world is a world in which language has lost its function and symbolic order has collapsed. In Apichatpong Weerasethakul and Tsai Ming Liang movies, body language plays a more important role than general language. t=The body performs semiosis, pointing to wildness, anti-civilization, rite, alienation, illusion, etc. At the root of this variety of semiosis is the common denial of Western material civilization which has been rapidly transplanted in modern Asian countries. In addition, while the body of the two directors' films are seen as a sign of wildness, or anti-civilization that contains the intention of escaping from the oppressive and inhuman modern civilization, the body as a sign of illusion, and embraces the will of resistance to civilization. The illusion of experience in their films is ultimately a manifestation of the will to resist the physical and emotional pressures of reality and to continue the irrational persistence.

Comprehensive understanding of the flood risk assessments via frequency analysis often demands multivariate designs under the different notations of return periods. Flood is a tri-variate random consequence, which often pointing the unreliability of univariate return period and demands for the joint dependency construction by accounting its multiple intercorrelated flood vectors i.e., flood peak, volume & durations. Selecting the most parsimonious probability functions for demonstrating univariate flood marginals distributions is often a mandatory pre-processing desire before the establishment of joint dependency. Especially under copulas methodology, which often allows the practitioner to model univariate marginals separately from their joint constructions. Parametric density approximations often hypothesized that the random samples must follow some specific or predefine probability density functions, which usually defines different estimates especially in the tail of distributions. Concentrations of the upper tail often seem interesting during flood modelling also, no evidence exhibited in favours of any fixed distributions, which often characterized through the trial and error procedure based on goodness-of-fit measures. On another side, model performance evaluations and selections of best-fitted distributions often demand precise investigations via comparing the relative sample reproducing capabilities otherwise, inconsistencies might reveal uncertainty. Also, the strength & weakness of different fitness statistics usually vary and having different extent during demonstrating gaps and dispensary among fitted distributions. In this literature, selections efforts of marginal distributions of flood variables are incorporated by employing an interactive set of parametric functions for event-based (or Block annual maxima) samples over the 50-years continuously-distributed streamflow characteristics for the Kelantan River basin at Gulliemard Bridge, Malaysia. Model fitness criteria are examined based on the degree of agreements between cumulative empirical and theoretical probabilities. Both the analytical as well as graphically visual inspections are undertaken to strengthen much decisive evidence in favour of best-fitted probability density.

In this paper, phase shifter has been designed and manufactured to apply to passive phase array seeker for Ka-band and its performance was confirmed. It was designed as a key element for conducting electric beam steering by adjusting the phase of the array element. Insertion loss of less than 1.5dB and phase accuracy of less than $10^{\circ}$(RMS) in operation bandwidth of 1GHz were checked. The performance identified by the actual fabrication was further analyzed by applying the beam pattern analysis based on the array synthesis theory. The effect of the final performamnce of the proven phase shifter on the performance and pointing error and angular accuracy of the passive phase array antenna beam pattern was analyzed. Then, the validation of the proposed phase shifter has been made.

Deactivation of aminoglycosides by their modifying enzymes, including a number of aminoglycoside O-phosphotransferases, is the most ubiquitous resistance mechanism in aminoglycoside-resistant pathogens. Nonetheless, in a couple of biosynthetic pathways for gentamicins, fortimicins, and istamycins, phosphorylation of aminoglycosides seems to be a unique and initial step for the creation of a natural defensive structural feature such as a 3',4'-dideoxy scaffold. Our aim was to elucidate the biochemical details on the beginning of these C3',4'-dideoxygenation biosynthetic steps for aminoglycosides. The biosynthesis of istamycins must surely involve these 3',4'-didehydroxylation steps, but much less has been reported in terms of characterization of istamycin biosynthetic genes, especially about the phosphotransferase-encoding gene. In the disruption and complementation experiments pointing to a putative gene, istP, in the genome of wild-type Streptomyces tenjimariensis, the function of the istP gene was proved here to be a phosphotransferase. Next, an in-frame deletion of a known phosphotransferase-encoding gene forP from the genome of wild-type Micromonospora olivasterospora resulted in the appearance of a hitherto unidentified fortimicin shunt product, namely 3-O-methyl-FOR-KK1, whereas complementation of forP restored the natural fortimicin metabolite profiles. The bilateral complementation of an istP gene (or forP) in the ${\Delta}forP$ mutant (or ${\Delta}istP$ mutant strain) successfully restored the biosynthesis of 3',4'-dideoxy fortimicins and istamycins, thus clearly indicating that they are interchangeable launchers of the biosynthesis of 3',4'-dideoxy types of 1,4-diaminocyclitol antibiotics.
