This study is to develop a logical model for the agricultural outlook information system. Since the outlook information concerns with the various types of decision making at the different but closely inter-related subsystems in the agricultural sector, importance of outlook information has been recognized since 1960's and the implementation of agricultural outlook was stated by the agricultural fundamental low in 1967. However, though various agenies collect relevant information, the official agricultural outlook has never been made public since then, mainly due to the quality of information. In this study, a infra-structure of new outlook information system was proposed, which aimed not only efficiency but also equity side. The equity issue is important because the distribution of information can be one of major causal factors in the income distribution and the bargaining power and therefore, the fairness of decision making process in the entire agricultural sector. The quality, rather than the size, of information system, is another major factor for its successful performance. Therefore, more emphasis was given to the value of information distributed rather than the number of users through the various interface modules.

워크플로우에서는 기업이 정한 목표를 달성하고, 기업의 현재의 불확실성과 불안정성을 제거하고, 현재의 치열한 경쟁을 극복하고, 장래에 보다 나은 기업이 되기 위해서, 기업의 모든 재 구성원과 자원들 사이에 존재하는 이질적 요소를 조정·조화시킨 후, 유기적으로 결합하여, 조직의 목적을 이루는 것이 중요하다. 본 논문은 크게 두 가지에 초점을 두고 있다. 첫 번째, 프로세스를 최적화시키기 위한 조정 기준을 제시한다. 이 전의 연구들에서는 프로세스를 조정 할때, 대부분 분석가의 직관과 경험에 의존했었다. 그러나, 본 연구에서는 이러한 분석가의 직관과 경험에 의존한 프로세스 조정을 최대한 줄일 수 있는 몇가지 간단하면서도, 강력한, 정량화 된 기준을 제시한다. 두 번째, 워크플로우에, 시간을 소요하는 처리와 하지 않는 처리로 구분 할 수 있으며, 처리 시간을 확률 함수로 파악함으로써 현실세계에 가까운 모델링을 할 수 있는, GSPN(Generalized Stochastic Petri-net)을 적용한 프로세스 모델링 방법을 제시한다. This paper proposes a method to analyze and design for workflow systems called GSWN(Generalized Stochastic Workflow Net), which is based on stochastic Petri-net, and an algorithm for workflow process optimization based on simulation analysis. The proposed modeling method was developed by adding workflow characteristics to stochastic petri-net. The proposed algorithm is consist of 4 major steps such as GSWN step, GSWN to matrix step, block establishing step, and process optimizing step.

<P><I>Physalis peruviana</I> L. (PP) is well known for its various properties, including its antioxidant property. In our previous study, the protective effects of PP against cigarette smoke-induced airway inflammation were confirmed. The purpose of the present study was to evaluate the anti-inflammatory effect of PP against ovalbumin (OVA)-induced airway inflammation. Treatment with PP inhibited the numbers of eosinophils and the levels of inflammatory cytokines, including interleukin (IL)-4, IL-5 and IL-13, in the bronchoalveolar lavage fluid (BALF) of animal models with OVA-induced allergic asthma. PP also significantly decreased the production of total immunoglobulin E in the serum. Lung sections stained with hematoxylin and eosin revealed that the influx of inflammatory cells was decreased in the lungs of mice treated with PP compared with cells in the OVA group. The increased expression levels of monocyte chemoattractant protein-1 (MCP-1) and T cell marker KEN-5 were also reduced following PP treatment in the lung tissues compared with those in the OVA group. The PAS staining results showed that PP attenuated the overproduction of mucus in the lung. Additionally, western blot analysis revealed that PP significantly downregulated the activation of nuclear factor-κB/p38 mitogen-activated protein kinase/c-Jun N-terminal kinase, and upregulated the expression of heme oxgenase-1 in the lungs. In an <I>in vitro</I> experiment, PP effectively reduced the levels of LPS-stimulated MCP-1 in a concentration-dependent manner. Taken together, these results indicate that PP has considerable potential in the treatment of allergic asthma.</P>

Advances in internet technology has made a cloud computing as a new computing paradigm. In cloud computing, computing resources are provided as scalable and on-demand services. One of fundamental issues for cloud services is to provide users with optimal services for their needs. In this paper, an ontology-based methodology for cloud service discovery is proposed and evaluated. For this, the context ontology to represent user`s situation is introduced. The proposed methodology can be expected to show good performance in discovering services by considering both user`s purpose and planned cost. According to the evaluation results, the proposed methodology shows that the cloud services are recommended optimally, as expected, to users due to different weights on each user`s purpose and costs.

As the importance of collaboration becomes critical in today's open and complex business environment network, the issues and solutions on compatibility and reusability between different kinds of applications are being increasingly impartant as well in systems analysis and design. And therefore. service-centered SOA is receiving attention in such business environment as a strategic approach that makes passible for prompt action according to the needs of users and business process. Various implementation methodologies have been proposed for SOA. however, in practical aspects most of them have some problems since they fail to propose specific policies in definition and identification of services for the exact user requirements and business situations. To solve or alleviate those problems. this paper suggests a new service identification model based on hierarchical ontology, where three different ontologies such as business ontology, context ontology and service ontology are proposed to define the relationship and design the link between user requirements. business process. applications and services. Through a suggested methodology in this paper. it would be possible to provide proactive services that meets a variety of business environments and demands of user. Also. since the information can be modified adaptively and dynamically by hierarchical ontology, this study is expected to play a pasitive role in increasing the flexibility of systems and business environments.

In this paper, we propose an integrated growth model of software reliability based on the non-homogeneous Poisson process. The model shows the relationship between several distinctively developed models. It also demonstrates not only each of the major attributes of the previous models but also the combined hidden attributes of those models. In addition, we derived estimates of the parameters of the integrated growth model and subsequently, tested the model with real world data. We found that our growth model is better than previous models in its flexibility to explain the reliability of software attributes and ability to apply to various situations in the real world.
