We demonstrate the electrochromic properties of $TiO_2$ nanotubes prepared by an anodization process and investigate the effects of heat treatment and viologen incorporation on them. The morphology and crystal structure of anodized $TiO_2$ nanotubes are investigated by scanning electron microscopy and X-ray diffraction. As-formed $TiO_2$ nanotubes have straight tubular layers with an amorphous structure. As the annealing temperature increases, the anodized $TiO_2$ nanotubes are converted to the anatase and rutile phases with some cracks on the tube surface and irregular morphology. Electrochemical results reveal that amorphous $TiO_2$ nanotubes annealed at $150^{\circ}C$ have the largest oxidation/reduction current, which leads to the best electrochromic performance during the coloring/bleaching process. Viologen-anchored $TiO_2$ nanotubes show superior electrochromic properties compared to pristine $TiO_2$ nanotubes, which indicates that the incorporation of a viologen can be an effective way to enhance the electrochromic properties of $TiO_2$ nanotubes.

Two novel copper(II) complexes, [Cu(dmamhp)$(H_2O)_2(SO_4)]_n$ (1) and [Cu(dmamhp)$(NO_3)_2(H_2O)]{\cdot}H_2O$ (2) [dmamhp = 2-dimethylaminomethyl-3-hydroxypyridine] have been synthesized and structurally characterized by single crystal X-ray diffraction analysis. Compound 1 displays a double one-dimensional chains structure, in which each chain is constituted with the distorted octahedral copper(II) complex bridged through bidentate sulfate ligands resulting in a coordination polymer. The bifurcated hydrogen bonds and $\pi-\pi$ interactions play important roles in the formation of the double chains structure. On the other hand, compound 2 adopts a distorted square pyramidal geometry around copper(II) ion and exists as a discrete monomer. There are intermolecular bifurcated hydrogen bonds and $\pi-\pi$ stacking interactions between the monomeric units. The magnetic properties revealed that the paramagnetic behaviors are dominantly manifested and there are no intermolecular magnetic interactions in both compound 1 and 2.

The present study was performed to investigate change in shimmer according to $F_{0}$ variation precisely, and to offer suggestions for a clinical application. The analysis for the present study was done by the fundamental frequency ($F_{0}$) and shimmer measurement results of the previous 120 Korean normal adults' voice study of Pyo et al. (2002), used three vowels, /i/, /a/, /and /u/. Through the analysis of 60 female samples from the previous study, we found that $F_{0}$ of the vowels was the highest in /u/, and the lowest in /a/, but, on the contrary, shimmer was highest in /a/and lowest in /u/. Thirty of 60 subjects showed such an inverse relationship between $F_{0}$ and shimmer, as a whole. In the vowel /a/, 47 of 60 subjects showed the increased $F_{0}$ and decreased shimmer, in /i/, 32 subjects, and in /u/, 33 subjects showed the same results. The decrease in shimmer means the improvement of voice quality, so by these results, we expect to answer the question why the patients with spasmodic dysphonia can improve their voice quality with increased pitched voice production.

The natural environment plays an important role not only in ecological sustainability, but also in human health. Growing attention has been focused on the health benefits of natural environments with increasing scientific evidence in this field. Urban green space has positive effects on individual and community health; thus, it is considered as social infrastructure. The natural environment promotes mental health by relieving psychological stress and depression. Physical health can be improved by experiencing nature, which reduces physiological stress and boosts the immune system. Several international initiatives have been undertaken to improve our understanding in this field and to utilize these benefits for health promotion. Interdisciplinary approaches are needed to promote human health through the natural environment in the fields of science, education, planning and policy.

Korean financial markets are rapidly integrating into the world financial markets as they are getting to open more widely. The Korean government enacted new law about financial investments. The environment of domestic financial markets are expected to be more competitive. As a result, the learning demand for financial engineering has been increased. However, the current state of education of financial engineering is in a beginning stage. The financial engineering consists of an appropriate mix of mathematics, statistics, finance and engineering. So interdisciplinary property of financial engineering requires lecturers to be cooperative to operate education of financial engineering. Another element of this education is cooperation of both academia and industry.

This essay is a critical study of the three models of practical theology that emerged in the second half of the 20th century: the critical correlational model (Sherrill, Browning), the hermeneutical model (Groome, Gerkin), and the faith community formation model (Westerhoff, Campbell). This essay first explores the central ideas of practical theologians who adhere to each of the three models and focuses on Christian education, pastoral counseling, and homiletics. This essay then critically evaluates the three models in accordance to the following four themes: how practical theology has 1) responded to the challenges of postmodernity, 2) engaged in dialogue with different types of theology, 3) participated in interdisciplinary dialogue, and 4) understood Christian practice. In conclusion, this essay suggests that the essential tasks of contemporary Christian education as practical theology include: 1) providing an active response to many challenges of postmodern, postsecular, postdigital, and posthuman era, 2) engaging in interactive dialogue with diverse forms of theology, and 3) facilitating interdisciplinary dialogue based on transversal rationality, and 4) establishing of the concept of Christian practice at the individual, ecclesial, social, public, ecological, and digital levels.

Development education started in some of developed countries of Europe since 1960s. Japan was interested in the development education with realizing the impotance of quality of life in the late of 1970s after high economical growth in 1960s. Just like Eroupe, development education in Japan was done to citizen by development NGOs. But under close cooperation with JICA and MOE, development education was gradually absorbed in formal education. Development education in Japan is done through interdisciplinary studies and the subjects. Geography national curriculum and textbooks in Japan show that the subject aimed to nurture Japanese in the world in the period from the late of 1960s to the late of 1970s. Thus the period can be named the sprouting time of education of development. But with entering the late of 1980s, geography national curriculum started to focus on fostering global citizenship to students. The turn in the educational aims can be counted as practical start of education of development. And education of development through geography was extended the most in the late of 1990s. But in the recent revised geography national curriculum, emphasis on education of development is reduced a little. It can be told that education of development in Japan arrives at the level of the full growth.
