Abeliophyllum distichum Nakai, a rare plant with distylous characteristics, is native to certain parts of the Korean Peninsula. It is registered on the IUCN Red List of Threatened Species as a globally endangered plant. This study was conducted to establish an appropriate local conservation management plan suitable for future A. distichum populations by comparing and analyzing the flowering characteristics and population size according to distyly based on the results of quantitative surveys in 14 regions, including 8 areas with native populations of A. distichum and 6 natural monument populations. The number of individuals appearing in each population group was surveyed, and the flowering individuals were identified by style as being either pin or thrum flower types as they were being examined and recorded on the site. In total, 13,130 individuals of A. distichum (7,003 flowering and 6,127 non-flowering individuals) were recorded, but the balance of the number of pin- and thrum-flowered individuals in each population was not significant (p<0.05), indicating an imbalanced state. In particular, the Yeongdong (YD) population was very disproportionate compared to other populations, suggesting that its genetic diversity was low and the possibility of inbreeding was high. The average flowering and fruiting rates by management unit were much higher in the natural monument populations (89.2% and 55.3%, respectively) than in the natural habitat populations (39.0% and 8.5%, respectively). It may be due to a difference in reproductive growth resulting from light inflow into the forest caused by the upper crown closure. The area of occupation (AOO) of A. distichum on the Korean Peninsula covered an area of 23,224.5 m². Although the natural monument population was smaller than the natural habitat population, its density was higher, likely as a result of the periodic management of natural monument populations, where the installation of protective facilities in certain areas restricts population spread. Conservation of A. distichum populations requires removing the natural monument populations suspected of anthropogenic and genetic disturbances and expanding the conservation priority population by designating new protected areas. Although the habitats of natural monument populations are managed by the Cultural Heritage Administration and local governments, there are no agencies that are responsible for managing natural habitat populations. Therefore, institutional improvement in the overall management of A. distichum should be prioritized.

This study examines how preference clarity and customer participation levels affect evaluation of fit toward customized services and also analyzes the effects of cultural difference between Korea and China that may cause variance in the evaluation of fit in the course of interaction with the prior two factors, preference clarity and customer participation level. It conducted a $2{\times}2{\times}2$ between-subjects factorial design adopting preference clarity, customer participation level, and difference of culture. The subjects were composed of 200 Korean and 200 Chinese. According to the analysis results, it is revealed that Korean consumers highly perceived fit toward customized services when their preference is clear and participation level is high, and they evaluate fit more favorably as participation level increased, while Chinese consumers' evaluation for fit deteriorated as participation level increased. The result shows that fit evaluation became more positive through participation when preference clarity is high in Koreans but not in Chinese.

In the late 16th century, the Theatrum Anatomicum or anatomical theatre opened in Leiden in the Netherlands. The theatre was open to a fee-paying audience of students, surgeons, and the public and soon settled down as one of the highbrow cultural activities in the city. This trend soon spread into Amsterdam, and Nicholaes Tulp appearing in Rembrandt van Rijn's was at the center of it. Human anatomy was not just an eyesore but started to get accepted as a cultural event for the civilized citizens of the time. It was with this backdrop that Rembrandt got inspired by this interesting scene of Tulp dissecting human body. Rembrandt well understood the changes of the time and captured them on canvas to attempt convergence between science and art.

Korean Landscape Garden may be described according to its stage of development. In the primitive agricultural era, the garden was preceded by vegetable yards and at this time rock arranging (Soo-Sok garden) was initiated together with the megalithis culture of dolmens, heavenly altars and tumuli. In the early Three Kingdom period palace gardens were built on a grand scale and toward the end of fourth century temple garden were introduced along with Buddhism. These gardens evolved to the flourishment of "HWAGE"(terraced gardens) rock arrangements of ZEN, early KOR-YO period. Especially since the middle of KOR-Yo period the "IM-CHUN"(forest and pond) garden became popular, while during Cho-Son period "HWAGE" in the back yard, pond and pool garden and "IM-CHUN" style country villa became fashionable. The Korea traditional Landscape garde may be characterized that first it is a nature Landscape style, which makes the maximum accomodation with the surrounding nature. Secondly, the Korean garden is built creatively by utilizing the elements of its climate and topography, Kogu-Ryo, Paik-Je great-Kaya and Sil-Ra had developed original a castle town plans and beautiful gardens rock arrangements which precede the equivalent style of China and set the prototype for Japan. The Landscape art of waterfalls and rock arrangements at An-Ap-Chi garden of 7th century has no equals in China and set the origin of pond style of Japanese garden.

Anthocyanin derivatives are an important of natural compounds responsible for the red, purple and blue colors in a large number of plants. This molecules are polymethoxy-derivatives of 2-phenylbenzopyrylium salts. Despite the beneficial properties of anthocyanins, the effectiveness of preventing or treating various diseases depends on bioavailability. Therefore, In this study, in order to investigate the electrical characteristics of anthocyanin derivatives, we investigated the electrochemical properties of derivatives by calculating the total energy, bandgap, net charge of anthocyanin derivatives using HyperChem8.0's PM3 method.

The purpose of this study was to investigate cross-cultural comparison of landscape preferences among Korean, Japanese and Western groups, and to get some clues to be used in judging this cultural influence. Moreover this study suggested fundamental data for design theory of modern landscape architecture. The results were as follows ; Natural factors including vegetation, water and rock, structural factors and spatial factors could be significant variables on Korean traditional landscape. The mean preference scores for both landscape element and landscape space were significantly different(p(0.01, p(0.05) with the Korean most perferred, the Western in the middle, and Japanese least. There were both differences and similarities in landscape preference among Korean, Japanese and Western groups.
