  • The demand of rural tourism industry has increased among the urbanites in South Korea, in due to the increase of leisure activity and the emergence of ageing society. Rural amenity resources are gaining various interests, in the value creation and promotion of tourism. In this study, the propensities of city dwellers were separated by life-style classification, and each affinity to the rural amenity resources was examined in accordance with the separation. A questionnaire survey of urbanites in the southern area of Gyeonggi-do, the most populous province in South Korea, was conducted to analyze the preference of city dwellers about rural amenity resource and life-style of themselves. For statistical verification, $IBM^{(R)}$ $SPSS^{(R)}$ Statistics 20 software was used for frequency, reliability, factor and multiple regression analysis of this research. The results of the statistical analyses found a noticeable characteristic in life-style classification. The affinities of urbanites can be classified into four congregations of life-style factors in this statistical model. Each congregation of the factors was named as 'Self-development-oriented', 'Leisure-oriented', 'Achievement-oriented', and 'Culture-oriented' life-style, to represent the characteristics for convenience' sake. Among these styles, only 'Self-development-oriented' and 'Achievement-oriented' showed the positive correlation with rural amenity resources in the multiple regression analysis. In addition, the rural amenity resources were also analyzed in accordance with the life-styles classification of urbanites. City dwellers showed the highest interest to the 'natural resource management facility resource' in natural resources, the 'traditional heritage resource' in cultural resources, and the 'community resource' in social resources. Meanwhile, they showed less interest to 'agricultural and scenery resources' in natural resources, 'specialty production resource' in cultural resources, and 'cooperative farming' in social resources. These characteristics can be constructed as meaning that the urbanites who concern self-development and achievement of their lives have high interest in rural amenity resources, and the main interest of them is not 'return-to-the-farm'(歸農) but 'return-to-the-home'(歸村).

  • The purpose of this study is to provide information how to locate a apparel store based on target age, merchandise's type and price. Three trade areas in Seoul are chosen: Myeong-dong which is the biggest trade area in Korea; Kangnam station one of representative Kangnam trade areas; and Myeongil-Dong a neighborhood trade area. This study is mainly performed by analysing the locations of the stores in the given areas. The result shows that the main apparel stores in Myeong-dong are casual wear stores for young people with the range of mid-high price. The stores in Kangnam station trade area also sell the casual wear for young people but they are mostly mid-low priced. In the trade area of Myeongil-dong, however, there are various kinds of mid-priced apparel stores for residents of all ages. Apparel stores for formal wear, casual wear, and formal-casual wear tend to be located side by side. But other kinds do not. These results show that affinity is found in some types of apparel stores by the analysis of the next-door apparel stores.

  • Colorants in green tea were extracted freeze-dried and analyzed to investigate the possibility of using as a natural dye. Fractionation of the colorants was carried out by column chromatograpy. Colorants in green tea were eluted into five fractions. All the fractions except fraction F2 showed absorption peakat 280nm. Fraction f2 showed absorption peak at 270nm and broad peak at 350nm, From the IR analysis it is speculated that fractions F2-F5 having similar stucture but different molecular weight are catechis. Silk fabrics dyes with fractions F1-F4 showed yellowish red color while sample dyed with fraction F5 showed red color. The colorants from green tea infusion was applied to silk wool nylon cotton and rayon fabrices. It showed relatively good affinity to protein and polyamide fibers bur low affinity to cellulose and regenerated cellulose fibers.

  • Our heterologous expression system of the human ferritin H-chain gene (hfH) allowed us to characterize the cellular effects of ferritin in yeasts. The recombinant Saccharomyces cerevisiae (YGH2) evidenced impaired growth as compared to the control, which was correlated with ferritin expression and with the formation of core minerals. Growth was recovered via the administration of iron supplements. The modification of cellular iron metabolism, which involved the increased expression of high-affinity iron transport genes (FET3 and FTR1), was detected via Northern blot analysis. The findings may provide some evidence of cytosolic iron deficiency, as the genes were expressed transcriptionally under iron-deficient conditions. According to our results examining reactive oxygen species (ROS) generation via the fluorescence method, the ROS levels in YGH2 were decreased compared to the control. It suggests that the expression of active H-ferritins reduced the content of free iron in yeast. Therefore, present results may provide new insights into the regulatory network and pathways inherent to iron depletion conditions.

  • The binding characteristic of oxomemazine to muscarinic receptor in the cerebrum, heart, and ileum were compared to those of pirenzepine to investigate whether oxomemazine could classify the muscarinic receptor subtypes. 〔$^3$H〕Quinucl idinyl benzilate(QNB) identified a single class of muscarinic receptors with apparent K$\sub$D/ value of about 60 pM in three tissues. Analysis of the pirenzepine inhibition curve of 〔$^3$H〕QNB binding to cerebral microsome indicated the presence of two receptor subtypes with high (Ki=16 nM, M$_1$-receptor) and low (Ki=400 nM, M$_2$-receptor) affinity for pirenzepine. Oxomemazine also identified two receptor subtypes with high (Ki=84 nM, On-receptor) and low (Ki=1 4 ${\mu}$M, O$\sub$L/-receptor) affinity in rat cerebral microsome, The percentage population of the M$_1$-and M$_2$-receptors to the total receptors were 61 : 39, and those of the O$\^$H/- and O$\sub$L/-receptors 39 : 61, respectively, However, the Hill coefficients of these two drugs for the inhibition of 〔$^3$H〕QNB binding to the heart and ileum were close to unity which indicated that these drugs bound to a uniform population of receptors in these two tissues. The Ki values for the low affinity sites of pirenzepine and oxomemazine in the cerebrum were similar to those of these drugs in the heart ileum. Both pirenzepine and oxomemazine increased K$\sub$D/ value for 〔$^3$H〕QNB without affecting the binding sites concentration and Hill coefficient for the 〔$^3$H〕QNB binding. Oxomemazine had a 10-fold lower affinity at Ma-receptors than at M$_1$-receptors, and pirenzepine a 8-fold lower affinity at O$\sub$L/-receptors than OH-receptors. Analysis of the shal low competition curves of oxomemazine for the H$_1$ receptors and pirenzepine for the O$\sub$L/-receptors yielded that 69% of the M$_1$-receptors were of the O$\sub$H/-receptors and the remaining 31% of the O$\sub$L/-receptors, and that 29% of the O$\sub$L/-receptors were of the M$_1$-receptors and 71% of the M$_2$-receptors. However, M$_2$ for oxomemazine and O$\sub$H/ for pirenzepine were composed of a uniform population. These results suggest that oxomemazine could discriminatethe muscarnic receptor subtypes and may subclassify the M$_1$-receptors into two subtypes.

  • A single uniform population of specific, saturable, high affinity binding site of $[^3H]QNB$ guinuclidinyl benzilate(QNB) was identified in the rat cerebral microsomes. The Kd value(37.2 pM) for $[^3H]QNB$ calculated from the kinetically derived rate constants was in agreement with the Kd value(48.9 pM) determined by analysis of saturation isotherms at various receptor concentrations. Dimenhydrinate(DMH), histamine $H_1-blocker$, increased Kd value for $[^3H]QNB$ QNB without affecting the binding site concentrations and this effect resulted from the ability of DMH to slow $[^3H]QNB-receptor$ association. Pirenzepine inhibition curve of $[^3H]QNB$ binding was shallow(nH = 0.52) indicating the presence of two receptor subtypes with high ($M_1-site$) and low($M_2-site$) affinity for pirenzepine. Analysis of these inhibition curves yielded that 68% of the total receptor populations were of the $M_1-subtype$ and the remaining 32% of the $M_2-subtype$. Ki values for the $M_1-$ and $M_2-subtypes$ were 2.42 nM and 629.3 nM, respectively. Ki values for $H_1-blockers$ that inhibited $[^3H]QNB$ binding varied with a wide range ($0.02-2.5\;{\mu}M$). The Pseudo-Hill coefficients for inhibition of $[^3H]QNB$ binding by most of $H_1-blockers$ examined except for oxomemazine inhibition of $[^3H]QNB$ binding were close to one. The inhibition curve for oxomemazine in competition with $[^3H]QNB$ was shallow(nH = 0.74) indicating the presence of two receptor populations with different affinities for this drug. The proportion of high and low affinity was 33:67. The Ki values for oxomemazine were $0.045{\pm}0.016\;{\mu}M$ for high affinity and $1.145{\pm}0.232\;{\mu}M$ for low affinity sites. These data indicate that muscarinic receptor blocking potency of $H_1-blockers$ varies widely between different drugs and that most of $H_1-blockers$ examined are nonselective antagonist for the muscarinic receptor subtypes, whereas oxomemazine might be capable of distinguishing between subclasses of muscarinic receptor.

  • 오늘날 정보시스템을 구축하는 모든 분야에서 컴포넌트에 기반한 개발(CBD : component based development) 방법이 주 흐름으로 등장하였다. GIS 영역에서도 컴포넌트의 개발 및 조립을 통한 시스템 구축을 권장하고 있다. GIS 영역은 다른 영역에 비하여 컴포넌트의 식별이 뚜렷한 업무영역(business domain)을 비교적 많이 가지고 있다. 이 영역은 비교적 산술적 기능을 많이 요구하는 부분이다. GIS 영역에서나 전사적(enterprise) 영역에서나 비산술적 기능 부분이 많이 존재함을 인식하여야 한다. 컴포넌트는 재사용성을 보장하여야 하는 특징을 가지고 있다. 재사용성이란 가능한 기능이 단순하고 최소의 크기를 가질 때 효용가치가 상승한다. 본 연구에서 GIS 컴포넌트를 추출하는 기법을 제시한 바가 있다. 본 연구에서는 친화력분석(affinity analysis)이란 기법을 통하여 GIS 컴포넌트를 추출하고자 한다. CBD에서는 UML을 활용하는 것이 기본으로 쓰임새(use case) 와 클래스는 UML의 핵심을 이루는 요소이다. 이 쓰임새와 클래스가 해당 업무영역 내에서 얼마나 친화력을 가지는가를 살펴보는 것이 친화력 분석의 목적이며, 이 분석 결과를 가지고 컴포넌트를 식별하게 된다. 이 친화력 분석은 GIS 영역뿐만 아니라 모든 업무영역에 활용이 가능하고 분석의 수행 절차가 복잡하지 않음으로 널리 활용할 수 있을 것으로 사료된다.
