율무와 현율무의 total methanol 추출물과 분획 한 후의 각 획분에서의 DPPH 라디칼 소거작용 및 tyrosinase 저해작용을 검색 비교하여 그 함량-작용간의 dose-dependent한 결과를 얻었다. 라디칼 소거작용은 율무의 n-butanol 분획이 가장 활성이 높아 standard로 사용한 BHT의 6.7배 정도의 농도에서 같은 $IC_{50}$값을 나타내었으며 $600\;{\mu}g/ml$ 이상의 고농도에서는 BHT와 거의 동등한 저해율을 보였다. 그러나 현율무에서는 total methanol 추출물을 분획한 후의 모든 획분이 total methanole 추출물의 활성보다 작아 분획에 따른 작용의 편재화를 이루지 못했다. Tyrosinase 저해작용도 모든 분획이 거의 유사한 저해율을 보여 역시 분획에 따른 activity의 편재화가 이루어지지 않았음을 알 수 있었으나 현율무의 chloroform 분획이 비교적 높은 활성을 보여 $IC_{50}$값이 $321.5\;{\mu}g/ml$이었다. 이는 활성이 확인된 trans-p-coumaric acid의 $IC_{50}$값이 $25\;{\mu}g/ml$, Kazinol E의 $IC_{50}$값이 $111.3\;{\mu}g/ml$임을 참조 할 때 분획으로서는 좋은 활성을 보였음을 알 수 있었다.

Regular maps and hypermaps are cellular decompositions of closed surfaces exhibiting the highest possible number of symmetries. The five Platonic solids present the most familar examples of regular maps. The gret dodecahedron, a 5-valent pentagonal regular map on the surface of genus 5 discovered by Kepler, is probably the first known non-spherical regular map. Modern history of regular maps goes back at least to Klein (1878) who described in [59] a regular map of type (3, 7) on the orientable surface of genus 3. In its early times, the study of regular maps was closely connected with group theory as one can see in Burnside’s famous monograph [19], and more recently in Coxeter’s and Moser’s book [25] (Chapter 8). The present-time interest in regular maps extends to their connection to Dyck\`s triangle groups, Riemann surfaces, algebraic curves, Galois groups and other areas, Many of these links are nicely surveyed in the recent papers of Jones [55] and Jones and Singerman [54]. The presented survey paper is based on the talk given by the author at the conference “Mathematics in the New Millenium”held in Seoul, October 2000. The idea was, on one hand side, to show the relationship of (regular) maps and hypermaps to the above mentioned fields of mathematics. On the other hand, we wanted to stress some ideas and results that are important for understanding of the nature of these interesting mathematical objects.

As a basic element for sustainable development, the residential housing industry is vital and fundamental for every country in the world. Therefore, this study examines the impacts of financial considerations on house purchase decisions by housing investors in Auckland, New Zealand. 110 completed questionnaires were statistically analyzed. For testing the proposed hypotheses, Structural Equation Modelling (SEM) was used. The results show that house prices, income, and credit accessibility significantly influence housing investors' purchase decisions in a positive direction. It appears that more expensive houses offer more promising returns such that housing investors having higher levels of income and access to loans are brave enough to invest in such houses. This study aims to present the key factors influencing house purchase decisions from the viewpoint of housing investors as fundamental groups of stakeholders in the property market, which is rarely examined in previous studies. The implication of this study is to provide guidelines for housing regulators in New Zealand to develop affordable housing prices through the availability of land banks. This study also offers practical contributions to housing investors, particularly by providing key guidelines to make effective investment decisions.

This article describes a new in-situ load test called the Hydraulic Cylinder Test (HCT) and its application to determine the geotechnical properties of soil-rock mixtures. The main advantages of the test are its easy implementation, speed of execution and low-cost. This article provides a detailed description of the equipment and the test procedure, and examines a case study of its application to determine the geotechnical properties of an earth-filled dam for a tailings pond. The containment dams of the ponds are made from blocks of gypsum and marl, obtained from the excavation of the ponds, mixed in a matrix of sands and clays. The size of the rocks varies between 1 and 30 cm. The HCT is particularly useful for determining the geotechnical properties of this type of soil-rock mixture. Nine HCTs were carried out to determine its strength (c, ${\phi}$) and deformation (B, G) properties. The results obtained were validated using the Bim strength criterion, recently proposed, and some pressure meter tests carried out beforehand. The properties obtained are used to analyze the stability of the dam using computer simulations and a modification to its design is proposed.

The two existing romanization systems in Korea, namely the recently promulgated Ministry of Education version sponsored by the National Academy of Sciences incorporating for the most part the McCune-Reischauer system and the Hangeul Haghoe or the Korean Language Society's version, must be judged as failures: He fennel for its disregard of Korean orthography and pronunciation, use of Latin-oriented pronunciation despite its assertion that English is the standard used, and the greatest weakness of all, its use of phonetic symbols neither found in regular typewriters, teleprinters, word processors and telex machines nor understood by laymen, sometimes not even by specialists. And the latter suffers from its undue emphasis on Korean orthography, Latin-oriented pronunciation being only partly capable of representing Korean pronunciation, among other shortcomings. Since the two existing romanization systems of Korean in South Korea, and romanization system of Japanese with Latin-oriented pronunciation are woefully inadequate, in today's world where English is used as if it were the international language almost all over the world, the present writer has invented a completely new system of romanizing Korean and Japanese by the so-called pseudo-phonetic method. This method employs the roman letters only and uses thorn in place of phonetic symbols as long as the letters thus applied are believed to have constant sound value. The English pronunciation is the standard used for this system.

Purpose: This study was done to examine the effects of aroma hand massage on stress response and sleep in hospitalized elderly patients. Methods: A non-equivalent pre-and post-test design was used. Sixty-six hospitalized patients were recruited using a convenience sampling method and assigned to the experimental (n=34) or the control group (n=32). For the experiment, bergamot, lavender, and roman camomile oil were mixed in 2:1:1 ratio to provide aroma hand massage to both hands of each patient in the experimental group for 5 minutes per hand, for 3 days. Post-test data collection was conducted three days after completion of the hand massage. Results: The experimental group had significantly lower stress score (t=-2.648, p=.010, and anxiety scores (t=-4.166, p=.000), and higher sleep measurement scores (t=2.328, p=.023) than those in the control group. Conclusion: These results indicate that short-term application of aroma hand massage for hospitalized elderly patients has a positive effect on hospitalization stress, anxiety, and sleep. Therefore, aroma hand massage should be applied as a nursing intervention to reduce stress response and enhance sleep in elderly hospitalized patients.

The theatre costume in English Renaissance which is scarce in its historical materials can be inferred and imaginarily reconstructed from classifying it according to types of theatre costumes and considering its specific form in that age. The history of fashion could be also approached in the light of theatre costumes and it might be some help to the present theatre costume. Thus the purpose of this thesis is for contributing to the study of theatre costume by inferring the English Renaissance theatre costume from classifications and research of its pattern in detail. This thesis consists of the overview of the periodical background of English Renaissance and then analysis of the stage surroundings ar that time and classification of the theater costume acording to the types and finally inferences of the pattern of forms of the theatre costume. The theatre costume in English Renaissance can be divided into these group:(1) for foreigners such as Roman Turk Spanish and Jews (2) for supernatural beings such as a nymph god, goddess, ghosts, and witches(3) for professionals such as a clown, a clergyman. doctors and senators(4) for cast of animals such as a lion a bear and pigs. In the Elizabethan period theatre costumes were used together with Elizabethan costumes on the stage. Generally the theatre costumes in the age were typically made of very expensive materials and spectacles to the audience and compensating for the poor stage settings.

An evaluation system for an electronic-nose concept using three types of metal oxide gas sensors that react similarly to the human olfactory cells was constructed for the quantitative and qualitative evaluation of aroma fragrances. Four types of aroma fragrances (lavender, orange, jasmine, and Roman chamomile), which are commonly used in aromatherapy, were evaluated. All the gas sensors reacted remarkably to the aroma fragrances and the good correlation of r=0.58-0.88 with the aromatic odor intensities by olfaction was confirmed. From the results of the analysis of an electronic-nose concept for classifying the characteristics of aroma oil fragrances, aroma oils could be classified using the fragrance characteristics and oil extraction methods with the cumulative variability contribution rate of 95.65% (F1: 69.65%, F2: 26.03%) by principal component analysis. In the pattern recognition based on the artificial neural network, the four aroma fragrances were 100% recognized through the training data of 56 cases (70%) out of 80 cases, and the pattern recognition rate was 57.1%-71.4% through the validation and testing data of 24 cases (30%). The pattern recognition success rate through all confusion matrices was 82.1%, indicating that the classification of aroma oil fragrances using the three types of gas sensors was successful.
