21세기 양돈산업의 전망은 환경문제, 사료생산, 동물복지 등 다양한 생산제한 요인에 의하여 국제적으로 돈육수급이 불안정할 것으로 예상되지만, 세계적으로 돼지고기 소비는 아시아 지역의 경기회복 등으로 증가추세에 있어 우리의 노력 여하에 따라서는 내수 소비확대 및 수출재개 등 경쟁력 있는 양돈산업으로 발전될 수 있다고 생각합니다. 또한 미래의 양돈산업 전개방향은 소비자 중심의 산업으로 변화되어 돈육의 건강개념과 영양적 가치 증진 및 식품의 안전성에 중점을 둘 것이며, 특히 소비자의 의식변화는 미래 양돈산업을 지배하는 결정적인 요인이 될 것입니다. 한편 유통경영 측면에서는 수직협력 시스템(Vertical co-ordination)과 효율적인 물류유통관리(MSCM) 시스템 도입이 가속화 될 것입니다. 즉, 소비자가$\codt$저마진에 의한 다량판매, 대규모 사육, 생산비 절감 기술개발에 주력할 것이라고 생각됩니다. 이에 따라 우리나라 양돈산업의 국제경쟁력 제고를 위하여 보다 시급히 해결되어야 할 질병$\codt$방역관리, 유통구조 개선, 고품질 돈육생산 및 위생$\codt$품질향상 분야에 있어서 중점 추진되어야 할 내용을 소개하고자 합니다.

The main objectives of this research are to analyse and evaluate the demolishing walls initiative in Daegu city as the collaborative urban environment improvement initiative in South Korea using the actor network theory concept. Local authorities are unable to effectively and efficiently improve urban environment because of their limited statutory and financial powers. This inability crucially led to the formation of the demolishing walls initiative in Daegu city with building a coalition of the local people, interest groups and public and non-governmental organisations in the operational processes in order to improve the physical and social urban environments. Furthermore, co-ordination between local authorities and landscape architecture specialists not only to change the way in which they tackle urban environmental problems but also to make the local people aware of their potential ability in positively improving the urban environment.

Trimethylglycine, commonly named betaine, is the most simple amphoteric molecule. It is completely vegetal (1,2), as it is produced in the sugar industry by industrial chromatography of molasses. While abundantly used in foods and diet supplements, many interesting applications in cosmetics have recently been investigated, like its capability to increase the volume and stability of foams in surfactant solutions. For its special chemical structure (it is the internal salt of a weak acid and a strong alkali) trimethylglycine is a solvent and buffering agent for strong acids and Lewis' acids. It allows to improve the efficiency of $\alpha$- and $\beta$-hydroxy acids in increasing the physiological rate of epidermal cell renewal, while keeping a low skin-irritation level. In oral care cosmetics, it acts as a mucous membrane protectant (3). For its special water co-ordination capability, its solubilising power, polymer swelling capability, after-feel improvement in hair products, skin moisturization and elasticity enhancing properties, trimethylglycine provides unusual characteristics to many products intended for skin maintenance (4).(omitted)

In this paper, we have described the Ramp Activity Coordination Expert System (RACES) which can solve aircraft parking problems. RACES includes a knowledge-based scheduling problem which assigns every daily arriving and departing flight to the gates and remote spots with the domain specific knowledge and heuristics acquired from human experts. RACES processes complex scheduling problem such as dynamic inter-relations among the characteristics of remote spots/gates and aircraft with various other constraints, for example, custome and ground handling factors at an airport. By user-driven modeling for end users and knowledge-driven near optimal scheduling acquired from human experts, RACES can produce parking schedules of aircraft in about 20 seconds for about 400 daily flights, whereas it normally takes about 4 to 5 hours by human experts. Scheduling results in the form of Gantt charts produced by the RACES are also accepted by the domain experts. RACES is also designed to deal with the partial adjustment of the schedule when unexpected events occur. After daily scheduling is completed, the messages for aircraft changes and delay messages are reflected and updated into the schedule according to the knowledge of the domain experts. By analyzing the knowledge model of the domain expert, the reactive scheduling steps are effectively represented as rules and the scenarios of the Graphic User Interfaces (GUI) are designed. Since the modification of the aircraft dispositions such as aircraft changes and cancellations of flights are reflected to the current schedule, the modification should be notified to RACES from the mainframe for the reactive scheduling. The adjustments of the schedule are made semi-automatically by RACES since there are many irregularities in dealing with the partial rescheduling.

The Korea Maritime Police Agency(KMPA) is the national maritime Search and Rescuee (SAR) authority with the responsibility to promote an efficient organization of SAR services and to coordinate the conduct of SAR operations within the Korean Search and Rescue Region(SRR). The maritime SAR operations shall provide an adequate and effective search and rescue services to minimize the loss by rendering aid to persons in distress and property in the marine environment. The essence of a successful search and rescue operation is the speed with which it is planned and carried out because survivors who need assistance and whose chances of survival diminish rapidly with time. This paper aims to propose an optimal allocation model of maritime SAR fleet in view of minimizing the search and rescue time. When maritime accidents occur, rescue units have to reach to the distress scene within the specified time. For this, SAR units must be redeployed to an advanced base so that Rescue Units(RU) can reach to the scene of distress in the shortest possible time. The Korean maritime SRR is divided into 180 sub-areas in consideration of an operational and technical ability of SAR units. The suggested model is verified through an empirical application to the Korean maritime SRR. And also the Rescue Vessels(RV) required is estimated for each Rescue Co-ordination Center(RCC).
