Though modern banking organs were established in Korea with the Kanghwa Treaty as a momentum, the benefit of financing at that time, which was mainly given to merchants and industrialists and traders, was extremely limited to the fishermen. The fishermen who were out of favor with the benefit of financing of modern banking organs were forced to rely on high interest loans, a category of usury capital, issued by the middlemen (the Kaekju) who lent them the deficit of their necessary funds. The fact was that in the field of fisheries the middlemen who issued usury capital played the leading part in fisheries financing of the Late Yi Dynasty. The middlemen, however, sqeezed a part or all of surplus products and on occasion even necessary products out of the fishermen by means of outward compulsion of economy. Moreover they put the fishermen further in trouble by putting-out system. In order to keep on with the production of aquatic products, the fishermen with little capital and no property established the antinomic rotations with the middlemen whose disadvantageous terms they were inevitably to accept. Thus the middlemen who did business with the fishermen exercised their authority over them, securing a strong activity foundation in the field of fisheries. But the traditional form of the Kaekiu was transformed and gradually declined in the field of fisheries according as the market rules were proclaimed in 1914.

Deep sea water has cold temperature, abundant nutrients and minerals, and good water quality that is pathogen-free and stable. Compared with surface water, deep sea water contains more nutrition salt, such as nitrogen and phosphor. Moreover, if has the good balance of minerals. Because of the ability of the spray drying process to produce a free-flowing power considering of spherical particles with a well-defined size distribution and the rapid drying times for heat-sensitive material, spray drying is attractive for a wide range of applications spray drying is a unique unit operation in which powders are produced from a liquid feed in a single processing step. Key component of the process are atomizer, spray chamber. Design of spray chamber should be based on the atomizer type, the production rate, and the particle size required. Because of the complex processes taking place during spray drying, traditional design method are based on pilot-plant tests and empirical scale-up rules. Modern technique such as CFD have a role to play in design and troubleshooting.

In order to quickly respond to the rapidly changing manufacturing environment, it is imperative for the system to have such capabilities as flexibility, adaptability, reusability, etc. One of the promising approaches for new manufacturing paradigm satisfying those capabilities is the fractal manufacturing system (FrMS). The FrMS can be optimized by reorganizing the structure of fractals through the dynamic restructuring process (DRP) to deal with the changes of environment. Through the DRP, the logical connections between fractals and roles of fractals are autonomously changed. To determine an appropriate fractal structure, certain rules are needed to build and evaluate alternative structures for fractals involved in the DRP. In this paper, an algorithm for the DRP-, which is invoked when some equipment are unavailable, is introduced and explained with examples.

Conventionally, ornament has developed around linear thinking based on Euclidean geometry, and been explained as simple and lucid natural Euclidean geometrical phenomena. The modular arrangement with vertical, horizontal and diagonal grids has been an organizing principle of classical ornament, but in digital era ornament is found not to be explained only with the principle of traditional arrangement due to the seemingly irregular complex forms. In that sense, this study presents the concept of digital ornament and examined the backgrounds of ornament in digital age, that are complex system and non-Euclidean geometry. Accordingly, the present study takes an approach by dividing new formal types of ornament into algorithmic form, hybrid form and dynamic form to find out a principle of pattern organization. Lately, architects who actively use computer for their architectural designs take the algorithmic strategies in nature and create various and complex patterns by simple rules. The patterns are not the repetition of the same, but the production of singularities. In addition, hybrid form by morphing shows a topologically flexible evolutionary transformation, and is used to create in-between transitional shapes from the source to target. Finally, the patterns by the interaction between the system components which are corresponded to the embedded forces emerge from dynamic simulation of the natural environment. Rather than objects itself, focus is given to the process of generating forms, and the ornamental patterns as the revelation of such implicit order provide not just the formal beauty but also spatial pathways for lights and air, maximizing the effects of lights.

ARM 프로세서는 다양한 임베디드 시스템에서 활용되고 있다. 또한 대부분의 ARM 프로세서는 C 프로그램을 입력으로 받아 GNU gcc 크로스 컴파일 방식을 사용하여 ARM 어셈블리 코드를 생성한다. 또한 생성된 목적코드의 질을 개선하고 효율적인 목적코드 생성하기 위한 다양한 연구가 진행되고 있다. 본 논문에서는 표준 C 프로그램으로부터 ARM 프로세서에 대한 목적코드를 문법-지시적 변환 기법을 이용하여 생성하며 성능평가 결과를 GNU gcc 크로스 컴파일 방식과 비교하여 제시한다. 본 연구에서 제시한 기법은 생성규칙을 확장하는 방법이 GNU gcc 크로스 컴파일러에 비해 간편하고 편리하다.

Many dispatching rules have been developed for the on-line control of product flow in a job shop. The introduction of a flexible manufacturing system (FMS) has added a new requirement to classical job shop control problem : the selection of machines by parts of different types. An FMS can keep a great deal of information on the status of the system, such as information on what is scheduled in the near future, with great accuracy. For example, the knowledge of the time when the next part will arrive at each machine can be neneficial for the routing. This paper tests the effects of the use of this knowledge for part routing on the parts flow time (sum of the time for waiting and service) under a simple routing procedure- a look-ahead routing procedure. A test under many operating conditions shows that the reduction of part flow time from the cases without using this information is between 1% and 11%, which justifies more study on this routing procedure at real production sites when machine capacity is a critical issue. The test results of this paper are also valid for other highly automated systems such as the semi-conductor fabrication plants for routing when the arrivals of parts in the near future are known.

그레이팅이라는 금속 제품의 자동 설계 시스템인 GDS (Grating automatic Drawing System)는 기본 설계 도면 (Plan Drawing)의 정보들을 바탕으로 여러 세부 도면들을 자동 생성하는 시스템이다. 그러나 GDS를 통해 자동 생성된 도면은 설계자들의 일반적인 치수 기입 요령을 부분적으로 만족시키지 못하고 있으며 또 치수 표시 간의 겹침 현상이 발생하여 설계자가 도면을 수정해야 하는 번거로움이 있었다. 전문가 시스템은 컴퓨터 시스템에 입력된 특정분야에서의 전문가적지식(knowledge)과 사실(fact)들을 이용하여 전문가의 지 식 이 요구되는 문제들을 해결하기 위해 만들어진 시스템이다. 본 논문은 이러한 문제점을 해결하기 위하여 선계 전문가들의 치수 표시법을 지식으로 하여 규칙 기반 전문가 시스템을 구성하였다.

The main objective of HACCP(Hazard analysis and critical control points) system is to provide a systematic preventive approach how to control the risks in food production process. Practically, the diet classification process performed at the one of the beginning steps of the HACCP system, makes an important role of determining food safety risks and how to control them in every control point according to the different risk level of the diet. In this paper, we propose an automatic diet classification method for HACCP system using XML(eXtensible Markup Language). In order to guarantee the diet classification accuracy, we design the XML schema and attributes represents the relationship of every diet and ingredients analysing the HACCP diet classification rules. Based on the XML schema and document generation method, we develope the proposed system as client and server model that implemented XML based HACCP diet information generation module and integrated HACCP information management modules, respectively. Moreover, we show the efficiency of the proposed system with experiment results describing the school food diet information as XML documents and parsing the diet information.

최근 멀티미디어 기술과 네트워크의 발전으로 멀티미디어 콘텐츠의 생성은 빠르게 늘어가고 있다. 그러나 이를 찾고 활용하는 기술은 부족하다. 이러한 문제를 보완하고 해결하기 위해 멀티미디어 콘텐츠를 위한 표준안들이 많이 있으나 멀티미디어 데이터 형식과 상호운용성을 표현하기에는 부족하다. 본 논문에서는 멀티미디어 콘텐츠를 상호 운용할 수 있도록 하는 온톨로지 기반의 콘텐츠 검색 시스템을 제시한다. 온톨로지는 MPEG-7의 MDS(Multimedia Description Scheme)와 같은 스키마 구조에 온톨로지 구축을 위한 규칙을 제시하여 구성한다. 이러한 온톨로지를 바탕으로 멀티미디어 데이터가 가지고 있는 연관성을 확장하여 의미론적 검색 시스템을 구축한다.
