Weakly coordinating anions show little affinity for binding to unfunctionalized iron(II) porphyrins. The electron-deficient 5, 10, 15, 20-tetrakis(pentafluorophenyl)porphinatoiron(II) compound is utilized in this study to demonstrate solution coordination by chloride, bromide and acetate ions. The binding strength of anions to the iron(II) porphyrin is reflected by a systematic change in pyrrole proton chemical shift in $^1H$ NMR spectra; the pyrrole resonance moves downfield when the ${\sigma}$-donor ability of anions is decreased.

This paper aims to offer a solution based on intelligent document classification to create a user-centric information retrieval system allowing user-centric linguistic expression. So, structures expressing user intention and fine document classifying process using EBL, similarity, knowledge base, user intention, are proposed. To overcome the problem requiring huge and exact semantic information, a hybrid process is designed integrating keyword, thesaurus, probability and user intention information. User intention tree hierarchy is build and a method of extracting group intention between key words and user intentions is proposed. These structures and processes are implemented in HDCI(Hybrid Document Classification with Intention) system. HDCI consists of analyzing user intention and classifying web documents stages. Classifying stage is composed of knowledge base process, similarity process and hybrid coordinating process. With the help of user intention related structures and hybrid coordinating process, HDCI can efficiently categorize web documents in according to user's complex linguistic expression with small priori information.

Due to the virtual nature of online businesses, online apparel stores need to enhance the consumer experience by utilizing store design attributes to provide their customers relevant and sufficient information. Since online apparel stores mainly communicate with their customers virtually and digitally, it is important to understand how consumers perceive and react to different design attributes commonly found on apparel stores' online websites. The purpose of this paper is to examine the importance of design attributes commonly found on online apparel stores' websites using three different importance measurements. The design attributes examined in this study include enlarged pictures, product detail pictures, product reviews by other buyers, coordinating items, and size measurement charts. The three different measurements used in this study include two direct measures and one indirect measure using conjoint analysis. Across the three different measures, both the men and women indicated that enlarged pictures represent the most important design attribute when they purchase clothes online followed by size measurement charts and they considered the availability of coordinating items the least important design attribute.

It is widely recommended that teachers should actively mediate students' engagement with tools such as manipulative materials. This paper is to help to parse classroom life so that both social and psychological aspects are accounted for and coordinated. Building on the theory of affordances from ecological psychology and the activity theory from sociocultural perspectives, the main strategy of this paper is to view manipulative materials as simultaneously participating in social and psychological activity systems. Within these activity systems it is charted how both mathematical affordances related to the structure of mathematical concepts and ecological affordances related to socially situated classroom practices need to be considered by teachers in effective mediation of mathematical manipulatives. This paper has three major sections. The first section develops a theoretical extension of Gibson's theory of affordances from natural to social environments. The second section introduces mathematical and ecological affordances using empirical data from a grade two elementary school classroom. The third section illustrates the need of coordinating the two affordances as embedded in different activity systems.

This study introduces the framework of the mutual recognition project of APEC Engineer and also tries to find out what we, Korean engineers have to do with this project. The mutual recognition framework consists of 2 main frameworks ; the substantial equivalence framework and the mutual exemption framework. The participating Economies have discussed and agreed on the framework of the substantial equivalency and have been producing APEC Engineers from the 1st, Nov 2000 based on this agreement. However, more discussions will be required from now on in order to finalize the mutual exemption agreement, even though there have been a lot of discussions including the workshop for the regulatory authority for the last 5 years. Here we have to study and find out what we have to do with this project and prepare for the bilateral agreements and the Coordinating Committee meeting to be held in Hongkong in Oct this year.

This paper considers a two-component assembly system that makes different types of purchasing contracts by component type and studies the issue of coordinating those contracts. Acquisition of type 1 component is based on the long-term contract. In contrast, type 2 component is intermittently purchased under the sort-term contract. We identify the structural properties of the optimal short-term contract and investigate how the changes in system parameters affect the optimal performance. To provide managerial insights, we compare the short-term and long-term contracts for type 2 component and discuss the conditions that make the short-term contract preferable to the long-term contract. We also present a result which shows that coordinating the contracts of type 1 and type 2 components can be significantly profitable over uncoordinating them.

The similar point of the 19 regional industrial clusters of Japan is that all of the clusters are not limited to an administrational district but rather covers a larger area. When a cluster covers a larger area, there is problem of acquiring responsible businesses and interactive planing. In order to overcome such a problem, private coordinating organizations have been installed and operated to connect and manage inter-activities of industries, universities, and research institutes. TAMA, a private coordinating organization, differs from other associations in a way that it does not deal with one specific field or business. TAMA rather dealswith various product-developing small to middle size companies by offering strategic support for the development of new technologies and expansion of new businesses. Product-developing small to middle size companies comparatively have their own abilities for technological development and marketing which is quite different from other subcontract companies and their relations to large corporations. In such aspect, product-developing companies are actually similar to large corporations with competitiveness in the world market.
