Today's network consists of a large number of routers and servers running a variety of applications. In this paper, we have designed and constructed the general simulation environment of network security model composed of multiple IDSs agent and a firewall agent which coordinate by CNP (Contract Net Protocol). 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 the execution of agents or a contractee, who performs intrusion detection. In the knowledge-based network security model, each model of simulation environment is hierarchically designed by DEVS (Discrete Event system Specification) formalism. The purpose of this simulation is the application of rete pattern-matching algorithm speeding up the inference cycle phases of the intrusion detection expert system. we evaluate the characteristics and performance of CNP architecture with rete pattern-matching algorithm.

With the development of hardware and 3D graphic technologies since the 1990s, video games have been evolving in the direction in which they wholly pursue illusions and movie formats, and thus they are considered to be media centered on spectacles. However, video games, due to their inherent characteristics, cannot be transparent media like the existing spectacular entertainments centering on optical illusions. In their structure, there can be found elements that continually disillusion players from visions. Strictly speaking, players are not lost in visions, but are kept a certain distance from internal contexts. Games rely not on illusion but on contracts with players which are similar to a kind of convention, clearing internal imperfections. This paper aims to identify and analyze disillusioning elements and discuss theatrical contacts between players and games. The purpose of this paper is to reconsider the awareness of video games as a spectacle entertainment and to help discover future directions for game culture.

As job mismatch intensifies in the employment market, the work based learning has emerged as a solution to this social problem. The so called Korean dual education system is expected to raise jobseekers equipped with knowledge and skills demanded by industry. This study intends to recommend an effective operational model for contracted education programs at higher institutions in order to support soft landing of Korean dual education system. Students of contracted education programs are adults graduated from vocational high schools and working for companies during weekdays. In consideration of the difficulties experienced by employee students, more flexible operation of academic affairs is required. To address these challenges, the recommended contracted education model includes such beneficial features as S-OJT courses, standard curriculum based on National Competency Standard, recognition of prior learning, flipped classroom, and tutoring system. In the last part, several directions for implementing the new contracted education model are discussed.

SW사업의 고유특성에 따른 하도급 만연과 대 중소 SW기업간 하도급계약의 협상력 불균형 등으로 인한 불공정 하도급 거래관행이 지속되어 국내 SW사업의 다단계 위계화 하도급구조가 지속되고 있는 실정이다. 이로 인해 SW사업 결과에 악영향을 미치고 역량있는 중소 SW기업의 사업의지를 약화시켜 SW산업 발전을 저해할 수 있어, SW사업의 하도급관련 국내외 법제를 조사 분석하고 그 시사점을 도출하여 SW사업 주체간의 공정거래를 담보할 수 있는 SW사업 하도급관련 법제 인프라 개선방향을 제시한다.

Construction Management is the overall management of the project as construction manager and the owner are united together. Construction manager's role is to conduct the overall or partial construction administration in the 'design, bid, build' process, in the owner's interests with maintaining technical neutrality. Construction manager is becoming one of new professionals in the building process and the contract defines their roles and the range of services, so high level of ethnics are required. This study suggests the legal status of the construction manager and the ethnic standards and the ethnic's characteristics. In conclusion, firstly, the legal characteristics of the administration of construction management are the delegations contract, the responsibility of negligence and the duty of due diligence, abided by the contract that ties between the owner and the construction manger. Secondly, the administerial characteristics of the construction management are the role of mediator, the service of professional technology, accountability to the owner and publicness. Thirdly, due to these characteristics, as a professional, the standard of ethnic assessment for the construction project manager are intention, act and result, so with the relation to that, morality, deontology and consequentialism have been suggested in this study.

The purpose of this study is to investigate how contract teacher librarians and contingent librarians working in school libraries experience burnout, and to provide basic data that will serve as a reference guide for finding counter measures. In order to achieve the purpose of the study, 100 librarians (teachers) from the school library in Seoul & Gyeonggi Province were surveyed to investigate how their societal characteristics, working environment and conditions, psychological state affect their burnout. As a result, school librarians (teachers) felt almost no burnout, but the most influential factor was self-esteem. In addition, the satisfaction with the compensation system was less than average, and there was a need for improvement.

정부는 건설산업기본법 일부 개정안을 지난 8월 11일 공포했다. 개정된 건산법은 앞으로 수급인이 일방적으로 하도급계약을 해제 해지하면 계약이행보증금 지급을 요청할 수 없고 하도급공사에 추가 변경사유가 발생한 경우 그 내용과 금액, 기간 등을 명시한 서면을 교부하도록 의무화했다. 한편 하자담보책임기간은 원칙적으로 법정기간으로 하되, 공사특성 등을 고려해 도급계약에서 따로 정할 수 있도록 하는 한편, 그동안 논란이 됐던 '완공일'의 개념도 '목적물의 관리 사용을 개시한 날과 준공검사를 완료한 날 중에서 먼저 도래한 날'로 명확히 규정했다. 이밖에 건설 관련 법령의 이해도 및 윤리의식 제고를 위해 신규 건설업자에 대한 교육제도를 신설하였으며, 건설 관련 공제조합 운영위원 수 상한을 확대하여 보다 많은 대표성 있는 조합원이 운영위원회에 참여할 수 있도록 했다. 개정된 건설산업기본법은 2016년 2월 12일부터 시행된다.

This study analyzed the correlation between each of the 12 influencing factors in FAR 16.04 and the decision-making process for construction contract types, using data from a total of 2,406 DoD Construction Acquisitions spanning from 2008 to 2022. The study considered 12 independent variables, grouped into 4 Characteristics with 3 factors each. Meanwhile, all other contract types were categorized into two types: Firm-Fixed-Price (FFP) and Cost-Reimbursement Contract (CRC), which served as the dependent variables. The findings revealed that FFP contracts significantly dominated in terms of acquisition volume. In line with prevailing beliefs, logistic data analysis and Analytical Hierarchy Process (AHP) analysis of Relative Weights from Experts' Survey demonstrated that independent variables like Uncertainty of the Scope of Work and Complexity found out to be increasing the likelihood of selecting CRC. The number of contractors in the market does indeed influence the possibilities of contract decision-making between CRC and FFP. Meanwhile, the p-values of the top 3 influencing factors on CRC from the AHP analysis-namely, Appropriateness of CAS, Project Urgency, and Cost Analysis-exceeded 0.05 in the binominal regression results, rendering it inconclusive whether they significantly influenced the construction contract type decision, particularly with respect to payment methods. This outcome partly results from the fact that a majority of respondents possessed specific experiences related to the USFK relocation project. Furthermore, influencing factors in construction projects behave differently than common beliefs suggest. As a result, it is imperative to consider the 12 influencing factors categorized into 4 Characteristics areas before establishing acquisition strategies for targeted construction projects.
