With the growing usage of the networks, the world-wide Internet has become the main means to exchange data and carry out transactions. It has also become the main means to attack hosts. To solve the security problems which occur in the network such as Internet, we import software products of network security elements like an IDS (Intrusion Detection System) and a firewall. In this paper, we have designed and constructed the General Simulation Environment of Network Security model composed of multiple IDSes and a firewall which coordinate by CNP (Contract Net Protocol) for the effective detection of the intrusion. The CNP, the methodology for efficient integration of computer systems on heterogeneous environment such as distributed systems, is essentially a collection of agents, which cooperate to resolve a problem. Command console in the CNP is a manager who controls tie execution of agents or a contractee, who performs intrusion detection. In the Network Security model, each model of simulation environment is hierarchically designed by DEVS (Discrete EVent system Specification) formalism. The purpose of this simulation is to evaluate the characteristics and performance of CNP architecture with rete pattern matching algorithm and the application of rete pattern matching algorithm for the speeding up the inference cycle phases of the intrusion detection expert system.

The purpose of this study was to analyze sensory evaluation, to assess visual serving size and plate waste estimates of daily menu, and the identify customer expectation, perception and satisfaction. Questionnaires of sensory evaluation, serving size and were waste were developed and hand-delivered to 2,520 people. A total of 2,255 questionnaires were usable: a 89.5% response rate. Customer satisfaction questionnaires were handed out to 700 customers: (100 each at seven operations). A total of 551 were returned completed (78.7%). The data was analyzed using the SAS package program for Descriptive Analysis, t-test and ANOVA. The result of sensory evaluation showed that 'taste' was 3.20, 'freshness' 3.17, 'temperature' 3.25, 'texture' 3.15, 'appearance' 3.12, 'overall evaluation' 3.21, so these were little higher than 「normal」, that is 3.0. There was positive correlation among 'taste', 'freshness', 'temperature', 'texture', 'appearance' and 'overall evaluation'(p<.001). Serving size score was 2.97 and plate waste was 4.87, thus plate waste percentage was about 22-33%. As the result of customer expectation, perception and satisfaction of menu quality, characteristics. Customer satisfaction was defined as the difference expectation and perception and customer perceptions in theis survey were lower than expectation, thus this result implied customers dissatisfied in all menu quality characteristics. IPA analysis showed that 'diversity of menu selection' and 'menu price' was included in A area 'Focus here'.

On account of the lack of education of Brazilian worker, this paper analyzed the characteristics of those professionals working in the production sector of timber houses. A sectoral survey was carried out with respective entrepreneurs to investigate the available professionals (career and contract types), evaluate the demands of skilled workers, and indicate solutions to improve the quality of labor qualification. Similarly, over 65% of sampled producers presented both direct-hired and outsourced workforce. For such contract ways, Civil Engineers and Architects were the main careers. Carpenters, Civil Engineers and Architects experienced on timber were the main sectoral demands. Timber Engineers have good potentials of service for this sector. The creation of courses on timber products can emerge as a key alternative to train people.

Currently, there is insufficient research on the construction management performance since the CM system was introduced in Korea. For successful completion of construction projects, active use of construction mangers on projects is necessary by introducing construction management to the projects. In view of this, this study analyzed the annual CM performance from 1996 to 2013 but for the past 5 years from 2009 to 2013, a detailed analysis was carried out. For different sectors, CM performances were divided into public and private sectors, for project types, construction, civil and others, for project phases, pre-design, design, construction and post-construction phases, for contract types, sole and joint contract types, for project scale, the amount of the projects was taken into consideration and they were divided into large, medium and small scales and for the types of projects, they were divided into, shops, department stores, shopping centers, hospitals, government buildings, hotels, accommodation facilities, factories, buildings for workshops, office buildings, stadiums, playgrounds, schools and other construction types and all the data divided into such categories was analyzed. The results in this study can be used as a basic reference for studies in analysing construction management performances.

With regard to the development of new drugs, what is most important for a Korean Biotech, where no global sales network has been established, is decision-making related to out-licensing of new drugs. The probability of success for each clinical phase is different, and the licensing amount and its royalty vary depending on which clinical phase the licensing contract is made. Due to the nature of such a licensing contract and Biotech's weak financial status, it is a very important decision-making issue for a Biotech to determine when to license out to a Big Pharma. This study defined a model called 'optimal timing for out-licensing of new drugs' and the results were derived from the decision tree analysis. As a case study, we applied to a Biotech in Korea, which is conducting FDA global clinical trials for a first-in-class new drug. Assuming that the market size and expected market penetration rate of the target disease are known, it has been shown that out-licensing after phase 1 or phase 2 of clinical trials is a best alternative that maximizes Biotech's profits. This study can provide a conceptual framework for the use of management science methodologies in pharmaceutical fields, thus laying the foundation for knowledge and research on out-licensing of new drugs.

In most countries the public library run as a public institution and a symbolic icon for a democratic society. Therefore public library's publicity is absolutely essential value and profit should not be made on their maintenance. More recently, as the government's budget spending increase, however, many local governments contract out to manage an entire library or new library system. Three main reasons could be identified. Firstly, alternative solutions for maintenance were supposed to save money. Secondly, contracting out provides an opportunity to improve the quality of service delivery. Thirdly, central government and some local authorities had very strong ideological reasons for contracting out of the public libraries. However, nothing proved that alternative maintenance had caused lower cost and better services in Korea. In this paper, the reasoning of a move from the traditional form of public library governance is discussed, as well as the advantages and disadvantages contracting out of the public libraries, and suggested various practical solutions in Korea.

In the former aviation law, only the Ministry of Land, Infrastructure and Transport has to provide air traffic services, In the case of providing aviation transportation service from civilian, such as aviation special education institution, private airfield installer, it was possible to carry out only by receiving a private contract from the government. But at the time of private consignment, the fact that the government has to bear the cost through the contract act. It is pointed out that it is a factor that hinders efficiency in the operation sector. Accordingly, in Article 85 of the Aviation Safety Act, which was enforced in March 2017, legal grounds were established to provide air traffic services excluding the Ministry of Land, Infrastructure and Transport. At the same time, we have introduced the air traffic services operating certification system, which enables the air traffic services to meet the requirements set by the Ministry of Land, Infrastructure and Transport in order to secure the safety of air traffic. In this study, we examine the major issues and problems of the small private control tower operated by the private institute in Korea. The effect of introduction of the air traffic services operating certification system which can introduce all the institutions which do not belong to the control agency in the former aviation law into the institutional system and the operation plan were examined.

The small/medium sized firms have big part and affect a national economy in the world. They underestimated in market until now make big change by standing out in international market. The Korean small/medium sized firms also get out of a domestic market stagnated and try to make inroads into international market. Especially, the Korean small/medium sized construction firms have very huge potentiality in international market globalized rapidly. But, the role of these firms actually have been insignificant in international market until now. This paper tried to present the alternatives to revitalize the overseas expansion of the Korean small/medium sized construction firms which have the potentiality. It analyzed the international contract trend of advanced construction firms to classify each group by using ENR data from 1996 to 2005, and presented the new standard of the Korean small/medium sized construction firms according to international contract portion, data, and legal bases. Finally, it used the expert interview method to refer to the revitalization of making inroads into international market.

Servitization presents an innovative model to create business value in the automotive industries. This study set out to introduce a servitization model based on the rental business of the tire industry and identify determinants to affect the renewal of contracts around the service types of servitization and the characteristics of customers. Independent variables include the service types, demographics and regions, and inflow channels in 163,742 contracts by case companies in the nation in 2016~2019 with the renewal of contracts as a dependent variable. Correlations between variables were analyzed through cross-tabulation and binary logistic regression analysis. The findings show that the contract renewal rate had positive(+) relations with customized service and negative(-) ones with vehicle maintenance service. There were differences in the contract renewal rate according to such customer characteristics as gender and region, but no clear correlations were found in the age group and vehicle type(domestic/foreign). Of the inflow channels, offline channels tended to have a higher renewal rate than online channels. At open malls, contract renewal increased by 8.4 times due to contract switches at offline channels. Based on these findings, the study discussed directions for practical strategies with regard to the development of new service, implementation of customer-centric servitization, and management of sales channels according to the servitization of manufacturers.

The rule of warranty in English insurance law was established in the second part of the $18^{th}$ century by Lord Mansfield, who laid the foundations of the modern English law of insurance contract and developed very different rule of insurance law, especially in the field of warranty. At the time of Lord Mansfield, warranty, that is, the promise given by the assured, played an important role for the insurer to assess the scope of the risk. Legal environments, however, have changed since the age of Lord Mansfield. English and Scottish Commissions proposed very dramatic reform of law in the field of warranty law to reflect the changes of legal environment through the Insurance Act 2016. This article intends to consider the legal implications through the comparative analysis between the new regime of warranty in the Insurance Act 2015 and MIA 1906. The major changes in the Insurance Act 2015 are summarized as following. First, Basis of the contract clauses in non-consumer insurance contracts should be of no effect and representations should not be capable of being converted into warranties by means of a policy term or statement on the proposal form. This requirement should not be capable of being avoided by the use of a contract term and the arrangement of contracting out by parties should be of no effect. Secondly, The existing remedy for breach of warranty, that is, automatic discharge of the insurer's liability, should be removed. Instead, the insurer's libility should be suspended from the point of breach of warranty and reattach if and when a breach of warranty has been remedies. Thirdly, A breach of warranty should genally be regarded as remedied where the insured ceases to be in breach of it. In the other hand, for time-specific warranties which apply at or by an ascertainable time, a breach should be regarded as remedies, if the risk to which the warranty relates later, becomes essentially the same as that originally contemplated by the parties. Fourthly, where a term of an insurance contract relates to a particular kind of loss, or loss at a particular location/time, the breach of that term should only give the remedy in relation to loss of that particular kind of loss, or at a particular location/time. Finally, whether a term of an insurance contrat relates to loss of a particular kind of at a particular location/time should be determined objectively, based on whether compliance with that ther would tend to reduce the risk of the occurrence of that category of loss.
