This paper aims to explore the cause and aspect of inter-ministerial policy conflict and its coordination in science and technology policy-making with the case of science and technology basic law-making process in Korea. This law-making processes are analysed through the three periods for the last 10 years starting 1992, such as law-formulation(1st) period, interim law-making (2nd) period, and final law-making(3rd) period. Based on these steps, it tries to concretely describe the phenomenon of policy conflict and the coordination mechanism among government departments and analyses the characteristics of dynamic interaction and mutual adjustment among the related agencies. The analysis is mainly focussed on the underlying causes and determinants of policy conflict, the development and coordination process of the conflict, the strategies and logics of the conflict participants, and eliciting some policy implications for effective policy coordination among government departments. Research results are summarized as follows. First, in science and technology policy-making the main causes of policy conflict among government departments are attributed to the difference of policy-orientation and jurisdiction-orientation of each agency. During the first period, the main aspect of policy conflict was policy-oriented, during the second, the main aspects of policy conflict were both policy-oriented and jurisdiction-oriented, and during the third, policy-oriented conflict was dominant. Second, the dominant typology and strategies of policy coordination which the participants used were vertical-political and horizontal-analytic approach. During the first period, horizontal and analytical approach were used, during the second, horizontal and political approach are mixedly used, and during the third, vertical and political approach were dominantly used. Third, The Korean National Assembly and the ruling party played a pivotal role in science and technology policy-making process(the basic law-making process) in particular during the final period.

Although consumer needs for better products force manufactures to put emphasis on design, often development of a product has been done without the formal process to consider consumer needs. In order to identify the implicit needs of customers and the areas of potential demand on a product, several analysis scheme such as QFD (Quality Function Deployment) has been developed. QFD, also known as the House of Quality, is the efficient tool ever created to tie product and service design decisions directly to customer wants and needs, i.e. VoC (Voice of Customer) To utilize this tool on a product design, first of all, the consumers attributes and the engineering characteristics must be exactly investigated. However there were only few studies about them on shoe design. Hence in this paper we developed an innovative framework for shoes design based on QFD. As a result, we uncovered 29 dominant human satisfaction dimensions as the consumers attributes for customer-oriented quality evaluation of a comfortable shoes. Here, 29 human satisfaction dimensions for a shoe design were identified as the dimensions that represent the human sensitivity and psychological feeling on comfortable shoes. Also, we proposed 60 human interface elements as the engineering characteristics. The relationships between human satisfaction dimensions and human interface elements were investigated. This study will help the designers and manufacturers clarify the conceptual and abstract aspect of the design evaluation by proposing a more systematic and process-oriented method.

The advance in Service-Oriented Architecture (SOA) and web services has led to the development of new types of a system in which heterogeneous service components can connect and compose to solve a complex business problem. In the SOA, even though these service components are valid in their functionality, there is a need to test their behaviors when those services are composited. In recent years, WS-BPEL has received a wide acceptance as a means of integrating distributed service components. To test the composite service, the existing testing techniques have been focused on the functional features based on the WS-BPEL process. However as SOA approach is applying to real-time software development, the performance of composite service becomes one of important issues. This paper proposes a technique to the performance testing of a composite service with WS-BPEL extension which combined with the concept of aspect. Our WS-BPEL extension has been made towards annotating aspect component which is measuring the response time of the composite service. This paper also explains the procedure of performance testing with on-line transaction system. Our technique can apply to choose an adequate component in service composition with considering the performance among several candidate web service components.

The Unified Modeling Language becomes popular to specify, visualize, construct, and document software-intensive systems, especially in supporting the design phase of software engineering. Most of designs in UML have focused on firm designing of software system structure. Recently, some researches have raised additional demands in many emerging complex software systems, such as aspect-oriented design. In this paper, we work on the dynamic aspect of policy-driven architecture. We present a UML-based high-level modeling of policy-driven management which is applicable in various application domains. In order to manage a number of activities of applications, dynamics and flexibility should be supported with policies consistently on different resources in the same context. Thus, a methodology of meta-modeling to represent dynamic aspects of policy-driven architecture is studied. Based on our methodology, we could achieve meta-modeling to develop a number of policy-driven management applications.

There are various studies about AOP(Aspect-Oriented Programming) which modularizes cross-cutting concerns like logging and security effectively. But, we need to utilize techniques which specify the information of aspects modularizing cross-cutting concerns and detailed join information between aspects and targets. We propose a specification technique for aspects which focuses on clarifying the join information between aspects and targets. The technique includes the activities of specifying aspects, defining priority, specifying join information, and specifying pointcuts. We describe the join matrix which represents relationships of aspects and targets and the pointcut specification which is made by analyzing the commonality of join points. The proposed specification technique supports detailed information of the aspects and the join information between aspects and targets so that we can use detailed information to implement aspects.

In this study, an attempt was made to classify the new generation by the conciousness of fashion and to make out positioning map, for brands of which each of the classified groups were aware. It's also intended to show a strategy brand marketing strategy by comparing the attribues that they considered important. The subjects of this study were gatheres into stratified sample groups from women whose age were ranged from 18 to 24 in Taejon. The subject brands of this study were Nice Claup. Y'sb. SYSTEM. i.n.v.u. On & On. EnC. ZOOC and Tomboy. which were selected because of high awareness. The results of this study were as below: 1. The new generation was grouped into a individuality-oriented group and an utility-oriented group. 2. As a result of analyzing brand image similarity, it's found that each group perceived the similarity differently. The individuality-oriented group perceived brand differentially more than the utility-oriented group. 3. concerning brand image preference, the individuality-oriented group preferred EnC most in light of self-expression and fashion, and preferred ZOOC most in view of utility. What was most preferred by the utility-oriented group was EnC in view of fashion and quality and ZOOC in the aspect of fashion, quality, price and design. 4. Regarding satisfaction level at brand image attributes, both of the groups showed satisfaction at On & On and Y'sb in light of self-expression. The individuality-oriented group was contented with SYSTEM's price and Nice Claup's utility and quality. 5. As a result of analyzing the groups' demographic variables, age and monthly mean income made a significant difference.

Aspect-oriented programming is the paradigm which extracts crosscutting concern from a system and solves scattering of a function and confusion of a code through software modularization. Existing aspect developing method has a difficult to extract a target area, so it is not easy to apply aspect mining. In an aspect minning, it is necessary a technique that convert existing program refactoring elements to crosscutting area. In the paper, it is suggested an aspect mining technique for extracting crosscutting concern in a system. Using abstract syntax structure specification, extract functional duplicated relation elements. Through Apriori algorithm, it is possible to create a duplicated syntax tree and automatic creation and optimization of a duplicated source module, target of crosscutting area. As a result of applying module of Berkeley Yacc(berbose.c) to mining process, it is confirmed that the length and volume of program has been decreased of 9.47% compared with original module, and it has been decreased of 4.92% in length and 5.11% in volume compared with CCFinder.

This study analyzed teachers' Pedagogical Content Knowledge (PCK) regarding the pedagogical aspect of the instruction of ratio and rate in order to look into teachers' problems during the process of teaching ratio and rate. This study aims to clarify problems in teachers' PCK and promote the consideration of the materialization of an effective and practical class in teaching ratio and rate by identifying the improvements based on problems indicated in PCK. We subdivided teachers' PCK into four areas: mathematical content knowledge, teaching method and evaluation knowledge, understanding knowledge about students' learning, and class situation knowledge. The conclusion of this study based on analysis of the results is as follows. First, in the 'mathematical content knowledge' aspect of PCK, teachers need to understand the concept of ratio from the perspective of multiplicative comparison of two quantities, and the concept of rate based on understanding of two quantities that are related proportionally. Also, teachers need to introduce ratio and rate by providing students with real-life context, differentiate ratios from fractions, and teach the usefulness of percentage in real life. Second, in the 'teaching method and evaluation knowledge' aspect of PCK, teachers need to establish teaching goals about the students' comprehension of the concept of ratio and rate and need to operate performance evaluation of the students' understanding of ratio and rate. Also, teachers need to improve their teaching methods such as discovery learning, research study and activity oriented methods. Third, in the 'understanding knowledge about students' learning' aspect of PCK, teachers need to diversify their teaching methods for correcting errors by suggesting activities to explore students' own errors rather than using explanation oriented correction. Also, teachers need to reflect students' affective aspects in mathematics class. Fourth, in the 'class situation knowledge' aspect of PCK, teachers need to supplement textbook activities with independent consciousness and need to diversify the form of class groups according to the character of the activities.

To investigate edge vegetation structure and edge species in Chiak Mountain National Park, field survey was executed from July to September, 1988. Canonpy drip-line type, cantilevered type and advancing type of edge vegetation were observed on site. The relative importance values of major species in each crown layer were changed along distance from edge to forest interior differently by aspect and present tree layer vegetation. Especially light-oriented edge species as codominant species were observed in Pinus densiflora forest interior at south slope and moisture - oriented species as codominant species were observed with light-oriented species in north edge beside torrential stream. No. of species and individuals by crown layer, species diversities and dissimilarities were decreased according to the distance from edge to forest interior, and edge depth was estimated as 15-20m. Dominant species of edge in shrub and ground layer were different by altitude and topographic locations; valley, ridge, summit and edge species at summit were not observed at other area. Floristic similarities between edge vegetations at different environments were affected by altitude, aspect and topographic location. Frequency classes of edge species were different by aspect, altitude and topographic location. Weigela subscssilis showed high frequency class in all environment conditions and Quercus mongolica, Lindera obtusiloba, Symplocos chinensis for, pilosa, weigela subscssilis, Fraxinus rhynchophylla, Actinidia arguta, Rubus crategifolius. Pinus densiflora, Aralia elata etc, were observed as edge species at all environmental conditions, respectively.

As the economy has picked up in recent years, so have the changes in the food industry. Due to trends in the family structure, two income households are becoming more common, including the in-crease of the female working population. Leisure activities and time continue to increase and to cause changes in the food industry which makes many kinds of food available to everyone, compared to previous times when people ate simply to live. This trend can be easily seen by considering the year to year increase of expenses for eating out. As life as become more and more complicated and full of variety, the trend towards a consumer oriented food industry has accelerated and is becoming a major element of Korean life. In the past, quantity of food was the most important aspect of the food preparation. Today, the dining experience includes social and cultural meanings which emphasizes customar oriented menus and services. In the restaurant business, successful management must consider the interests of both employees and custmers and must be run efficiently and probide good service.
