This study analyzes the state and products of shopping malls that sell naturally dyed products in Japan. In this study, 37 natural dyeing shopping malls were selected. The results of this study are as follows. There are many natural dying internet shopping malls located in the areas of Tokyo, Kyoto, and Okayama. The most frequent dyes were indigo, followed by akane, persimmon, mud, vegetation, and tea. The highest ordered product categories were accessories, followed by adult clothes, and interior decoration products. The most frequent products were adult hats, followed by towels (handkerchiefs), scarves, T-shirts, and bags. For the price of products, 3,000-4,000${\yen}$ was the highest for T-shirts, with 2,000-3,000${\yen}$ and 4,000-S,000${\yen}$ for newborn baby and child clothing, 5,000-10,000${\yen}$ for hats and bags, 3,000-4,000${\yen}$ for scarves, and 1,000-2,000${\yen}$ for towels (handkerchief). Concerning product information, most of the shopping malls offer the product size and the product explanations, but over half of them did not show the properties or directions for handling the product.

The environment is composed of at least two components, the natural and the human-made one. Nonetheless, the environment is being used to connote the natural environment. Moreover, even though the components of environment exist in a mutual relationship as a mechanism, it is rare to study the components of environment and their system as a mechanism. With such an implication, this paper aims to identify the components of environment and their system. The components of environment can be categorized by two criteria. One is the subject of creating environment, and the other is the visuality of environment. The former categorizes the environment into the natural and the human-made one, and the latter into physical and nonphysical one. Integrating the two criteria into a framework, the environment can be categorized into the natural, the human-made physical, and the human-made nonphysical environment. The three categories of environment exist interrelatedly in a mechanism being characterized as a mutual impact. The mechanism may be called the environmental system. The environmental system can be analyzed in terms of two dimensions. One is a human-inclusive system. The other is a human-centered system. The former is a framework that includes humans as a component of environment. The latter is a framework that humans are the subject of the environment, and the others surrounding human life are the object of the environment. The former is defined as a circular system of material and energy, while the latter is defined as a mutual subjective-objective system.

This study was conducted to analyze arthropod community patterns in smallrice fields managed by different cultural methods [Conventional and Low Input Sustainable Agriculture(LISA)] in Suwon in 1995 and 1996. A half of nitrogen fertilizers and a quarter of pesticides were applied in the LISA field compared to in the conventional field. Total 15 orders and 43 families of arthropods were collected in two years. No differences were found in arthropod abundance and arthropod species composition between two differently practiced fields. The arthropod community was analyzed using guild categories. The arthropods were found in the order of 'pest(phytophag)>natural enemy>non-pest' in their densities. The pest species were mainly Homoptera and dominated by Delphacidae (Nilaparvata lugens Stal and Sogatella furcifera Horvath). They constituted > 80% of pest abundance. The spider was the most dominant group in the natural enemy and constituted > 90% of natural enemy abundance. Hunting spiders constituted > 60% of spider abundance and were dominated by Pirata subpiraticus Bos. et Str.(Lycosidae). Pachygnatha clerki Sundevall(Tetragnathidae), Gnathonarium dentatum Weider and Ummeliata angulituberis Oi(Erigonidae) were the dominant species in webbing spiders.

The synthesis of chiral 1,2-amino alcohols has been an area of intense study in the synthetic and industrial fields, because of their important roles in organic synthesis as fundamental building blocks and their occurrence in a number of natural products. drugs. and chiral auxiliaries or ligands. General methods for the synthesis of these compounds can be divided into two large categories: functional group transformations and the C-C or the C-N bond formations. (omitted)

The recent development of biodegradable polymers for drug delivery system (DDS) has been investigated. The biodegradable polymers for DDS are mainly discussed in two categories: one category is natural biodegradable polymers such as polysaccharides, modified celluloses, poly(${\alpha}$-amino acid)s, modified proteins, and microbial biodegradable polymers; the other is synthetic biodegradable polymers such as poly(ester)s, poly(ortho ester)s, poly(phosphazene)s, poly(anhydride)s, poly(alkyl cyanoacrylate)s, and multiblock copolymers. The bioconjugate polymeric drug delivery systems have been also proposed for the design of biocompatible polymeric controlled drug delivery.

Basic objective in cluster analysis is to discover natural groupings of items or variables. In general, variable clustering was conducted based on some similarity measures between variables which have binary characteristics. We propose a variable clustering method when variables have more categories ordered in some sense. We also consider some measures of association as a similarity between variables. Numerical example is included.

질의응답 시스템이 정보검색 시스템과 다른 중요한 점은 질의 처리 과정이며, 자연어 질의 문장에서 사용자의 질의 의도를 파악하여 질의 유형을 분류하는 것이다. 본 논문에서는 질의 주-형을 분류하기 위해 복잡한 분류 규칙이나 대용량의 사전 정보를 이용하지 않고 질의 문장에서 의문사에 해당하는 어휘들을 추출하고 주변에 나타나는 명사들의 의미 정보를 이용하여 세부적인 정답 유형을 결정할 수 있는 질의 유형 분류 방법을 제안한다. 의문사가 생략된 경우의 처리 방법과 동의어 정보와 접미사 정보를 이용하여 질의 유형 분류 성능을 향상시킬 수 있는 방법을 제안한다.
