Han-Ki Choi($1803{\sim}1877$), who was a scholar in Joseon dynasty, understood geography into a synthetic category of chorography, cartography, earth science and fengshui. He focused on chorography and map as a leading position in geography. The purpose of the research of Han-Ki Choi was to examine the way of Heaven, and then to make clear the way of Humanity. The identity of the geography for Han-Ki Choi was a practical science that useful for the ruling over the country and the welfare of people. He emphasized the nature of relationship with humans in geography. The system of Han-Ki's Chi-hak came from the basis of a geography, on the contrary, his geographical works were accomplished on the ground of the Chi-science. The chorography, Chi-hak of the earth and the earth science were composed into systematic organization for achieving the goal of the Chi-geography.

Purpose: This study was conducted to examine how patients' coping style and social support affect post-traumatic stress disorder (PTSD) in breast cancer patients who are treated with chemotherapy. Methods: The sample consisted of 134 outpatients who received breast cancer treatments at the cancer clinic of a university hospital. The collected data were analyzed by frequency, percentage, t-test, ANOVA, ${\chi}^2$-test, Pearson correlation coefficients using SPSS for Windows, version 18.0. Results: Among total, 26.9% of patients were classified into a high-risk PTSD group. In the high-risk group, a positive correlation was found between active and passive coping styles and between social support and active coping styles. Conclusion: In this study, the stronger the social support was, the more active the coping style was for high-risk PTSD patients with breast cancer. Considering the fact that cancer requires life-long self-management, strong social support could improve patients' healthcare capability. Furthermore, solid social support could effectively reduce the stress level and improve the quality of life for breast cancer patients in the high-risk PTSD group.

This Study was to examine whether high school students' autonomy support and beliefs of intelligence ability influence their self-regulated strategies. Of the 600 high school students surveyed from 3 high schools in two metropolitan cities, Korea, 478 completed and returned the questionnaires yielding a total response rate of 79.7%. Among the final sample consisted of 109 gifted students (22.8%), 190 high-achieving non-gifted students (39.7%), and low-achieving non-gifted students (37.4%). Measures of students' perceived autonomy support (i.e. from parents, teacher, peer), beliefs of intelligence ability (i.e. incremental, entity) and self-regulated strategies (i.e. managing environment and behavior, seeking and learning information, maladaptive regulatory behavior). Spearman's rho(${\rho}$) indicated that students' achieving level was positively associated with autonomy support (i.e. parents, teacher), beliefs of intelligence ability (i.e. incremental) and self-regulated strategies (i.e. managing environment and behavior, seeking and learning information). However, students' achieving level was negatively associated with beliefs of intelligence ability (i.e. entity) and self-regulated strategies (i.e. maladaptive regulatory behavior). Hierarchical multiple regression analyses showed that students' perceived autonomy support (i.e. from teacher) and beliefs of intelligence ability (i.e. incremental) were the crucial contributors for enhancing students' self-regulated strategies. Results are discussed in relation to theoretical implications and school settings.

We developed laminated cylindrical scaffolds composed of poly(lactide-co-glycolide)(PLGA) and keratin, and investigated their potential for tissue engineering and disk regeneration. The scaffold was designed to have two parts, i.e. inner cylinder and outer disk, to mimic a natural disk. The outer disk was composed of PLGA and the inner cylinder was prepared using PLGA film or PLGA/keratin hybrid film. In this study, we investigated the effects of keratin on the growth and proliferation of annulus fibrous(AF) cells in the cylindrical scaffolds. Scaffolds containing PLGA/keratin films showed a significantly higher cell proliferation and expression of collagen I and II than the counterpart with PLGA films. Keratin containing scaffolds also exhibited an excellent mechanical strength, demonstrating that keratin influences the proliferation of annulus fibrous cells. The results provide valuable information on PLGA/keratin films for tissue engineered disk regeneration.

In this study, porous metal (O.D. = 10 mm, length = 10 mm, 316 L SUS, Mott Corp.) and ${\alpha}$-alumina tube (O.D. = 10 mm, length = 50 mm, Pall, German) support was modified with suspension sols, which were consisted of $3{\sim}4{\mu}m$ and 150 nm size of ${\alpha}$-alumina particle in the water or silica-zirconia colloidal sol. The porous support was fabricated by dip coating method for 5 seconds with suspension of alumina particles. After drying at $100^{\circ}C$ for 1 h, it was calcined at $550^{\circ}C$ for 30 min. It was repeated several times in order to decrease big pore on support. The surface roughness and largest pore size on the porous support was decreased by increasing coating times with $3{\sim}4{\mu}m$ size of ${\alpha}$-alumina particle and alumina coating with 150 nm size of ${\alpha}$-alumina particle served as further smoothening the surface and decreasing the pore size of the substrate. And the silica-zirconia membranes were successfully prepared on the modified porous metal and ${\alpha}$-alumina supports, and showed hydrogen permeance in the range of $1.8-8.4{\times}10^{-4}mol{\cdot}m^{-2}{\cdot}s^{-1}{\cdot}Pa^{-1}$ and $3.3-5.0{\times}10^{-5}mol{\cdot}m^{-2}{\cdot}s^{-1}{\cdot}Pa^{-1}$, respectively.

Purpose: Maternal-fetal attachment in a pregnant woman is important for her health and for her child's emotional stability. This study was done to identify the contribution of maternal fatigue, social support, and Taegyo to maternal-fetal attachment based on a survey of pregnant women. Methods: The study was a descriptive correlation study. Participants were 211 from two women's health clinic centers. Data were analyzed using t-test, ANOVA, Pearson correlation coefficients and stepwise multiple regression. Results: Mean scores for maternal-fetal attachment, Taegyo, maternal fatigue, and social support were 93.74 (range 25-125), 64.76 (17-85), 24.12 (10-40), and 54.43 (22-132), respectively. There were significant differences in maternal-fetal attachment according to parity, breast feeding experience, and putting prenatal education into practice. Multiple regression analysis showed that the key determinants of maternal-fetal attachment, were Taegyo (${\beta}$=.67), maternal fatigue (${\beta}$=.21), and social support (${\beta}$=.13), and these explained 55% of the total variance of attachment. Conclusion: The results suggest a need to encourage Taegyo in prenatal management program and provide methods for fatigue resolution and promotion of social support.

Rapid growth of information and communication technology and changes in college student characteristics require for university instructors to diversify instructional improvement efforts. Technological Pedagogical Content Knowledge (TPACK) is a capacity that instructors need to build for making instructional design based on consolidated technology. Accordingly this study explores instructors' awareness of the importance and performance of TPACK and to inquire into their relationships with epistemological beliefs and social support as relevant factors through a survey carried out with 264 instructors. The study has shown that there is a significant difference between college instructors' awareness of the importance of TPACK and their awareness of its performance. Furthermore, it has shown that the awareness of importance and performance of TPACK is significantly related to the social support, and that among the sub-factors of the social support, significant influences are observed from the emotional support on their awareness of the importance of TPACK and from the informational support on their awareness of the performance of TPACK. These results provide fundamental data for measures to develop and support TPACK capacity of college instructors, suggesting that it requires a teaching support strategy to enhance social support for instructors above all things.

Thin film composite (TFC) polyamide (PA) membranes were prepared on polyester (PET) nonwoven reinforced polysulfone supports for forward osmosis (FO) processes. PSF (polysulfone) supports were prepared via the phase inversion process from PSF casting solutions in dimethyl formamide (DMF) solvents (19 wt%) by using a PET nonwoven (thickness of $100{\mu}m$) as a mechanical reinforcing material for reverse osmosis (RO) membrane. The PSF support from 19 wt% of DMF/PSF casting solution showed sponge-like morphology and asymmetric internal structure. To reduce the internal concentration polarization in FO operation, thin ($20{\mu}m$ of thickness) nonwoven-supported PSF supports were prepared by using PSF/DMF casting solution (9~19 wt%). A desirable support structure with a highly porous sponge-like morphology were achieved from the thin nonwoven-supported PSF layer prepared with 9~12 wt% casting solution. A crosslinked aromatic polyamide layer was fabricated on top of each support to form a TFC PA membrane. The tested sample from 12 wt% of DMF/PSF casting solution presented outstanding FO performance, almost 5.5 times higher water flux (24.3 LMH) with low reverse salt flux (RDF, 1.5 GMH) compared to a thick nonwoven rainforced membrane (4.5 LMH of flux and 3.47 GMH of RSF). By reducing the thickness of the nonwoven and optimizing PSF concentration of casting solution, the morphology of the prepared membranes were changed from a dense structure to a porous sponge structure in the boundary area between nonwoven and PET support layer.
