Many companies are adopting Information System (IS) operation outsourcing to focus on their core competencies and enhance operational efficiency. However, most of them employ a headcount-based pricing model, which often leads to exhaustive negotiations over contract costs without objective criteria or systematic frameworks. This headcount-based outsourcing contract environment results in low motivation/incentives for both client companies and IT service providers to improve productivity, efficiency, and quality, which poses challenges in securing a competitive advantage. This study introduces the development process of an IS operation outsourcing pricing model, which was collaboratively developed and agreed upon for implementation in actual contracts by an IT service company of a conglomerate. Also, the study underscores the activities undertaken to secure IT service competitiveness based on this model so as to deliver a practical guide for companies seeking to transition their outsourcing contract methods.

In December 2012, the Ministry of Land, Transport and Maritime Affairs and Ministry of Knowledge Economy held a commission and distributed a standardized logistics contract between the shipper and the logistics companies in order to spread and to promote contract standardization. With such background in place, this study examines the leading research on different types and attributions in present logistics contracts in order to propose guidelines for creating contract clauses that would lead to a win-win relationship among the parties involved in the logistics outsourcing relationships. This study further compares and contrasts the concreteness of local and international logistics contracts through case studies, and provides practical thought-provoking points on concretization of clauses on potential risks and additional expenses for local logistics companies when signing logistics contracts. Firstly, the composition and contents of both local and international logistics contracts are similar in the way that both deal with the basic principles between the concerned parties such as the following: contract terms, validity, scope of work, operational procedures, payment terms, and dispute resolutions. Secondly, for flexibility of potential dispute resolution, both logistics contracts define the definition of dispute and follow the classical contractual approach of dispute resolution through third-party arbitration. Thirdly, compared to local contracts, international logistics contracts provide more concretized and specific clauses on the occurrence of potential risks and hazards; on the other hand, compared to international logistics contracts, it seemed that local contracts contained more clauses in favor of the shipper. This research then suggests ideas to eliminate the classic tradition - logistics companies enduring the damages that occur as a result of the structural differences between the shipper and the logistics companies - through efforts to actively negotiate in advance the predictable problems and risks and by reflecting the mutually agreed points in the contract, and further offers guidelines on contract concretization for distribution of standardized logistics contracts in the future.

This paper analyzes a situation where multiple targets are exposed to a potential terrorist attack. The probability of an attack is determined endogenously in a game where a terrorist chooses the target while the targets independently determine the level of deterrence. As each target tries to divert an attack to others, the symmetric equilibrium becomes suboptimal and exhibits dispersion in the level of deterrence. The analysis shows that the first best deterrence level may be achieved when the targets can write a binding risk-sharing contract. Such a contract has limited applicability however as it suffers from a potential verification problem.

As the importance and the need for network security is increased, many organization uses the various security systems. They enable to construct the consistent integrated security environment by sharing the vulnerable information among firewall, intrusion detection system, and vulnerable scanner. We construct the integrated security simulation environment that can be used by some security system model. 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. We compare the selection algorithm in the CPN with the Fuzzy Controller for the effective method to select the agents.

The purpose of this study is to investigate the structural relationship among psychological contract violation, job burnout, and turnover intention of MZ generation workers in small and medium enterprises. The sample collected through online and offline was 144 units of millennial generation and 140 units of Z generation. The results of analysis using structural equations showed that psychological contract violation had a positive (+) effects on turnover intention and job burnout, and job burnout also had a positive (+) effect on turnover intention. In the relationship between psychological contract violation and turnover intention, job burnout had a partial mediating effect.

강섬유 보강 콘크리트는 콘크리트 내에 강섬유를 임의로 투입함으로써 취성의 콘크리트 물성을 연성적으로 향상시킴과 동시에 압축, 인장, 휨 강도를 증가시킨 새로운 구조 신소재라고 할 수 있다. 과거 70년대가 SFRC의 재료적 물성에 대한 실험적 시기였던 반면 현재는 현장에 SFRC를 시공하는 응용단계라 할 수 있다. SFRC의 우수성은 선진 외국의 경우 일반적으로 기업, 정부, 계약관계자 등에게 잘 인식되어 있어 이미 많은 시공현장에서 응용되고 있다. 이로 인하여 외국(미국, 일본, 유럽 등)의 경우 구조적으로 안정되고 경제적인 구조물을 실현하고 있으나 국내의 경우는 안타깝게도 SFRC에 대한 인식이 아직 일반화되어 있지 않으며 시공현장도 매우 드문 실정이다. SFRC에대한 연구는 국.내외 학회에서 꾸준히 연구, 개발하고 있으며 이들 연구결과가 경제적이고 우수한 구조물을 실현하는데 기여할 수 있기를 기대한다.

The purpose of this study was to better understand the influence of psychological contract breach in deluxe hotel culinary staff memeberss on job satisfaction and turnover intention. Based on a total of 280 samples obtained for empirical research, this study reviewed the reliability and fitness of the research model and verified a total of 4 hypotheses using the AMOS program. The hypothesized relationships in the model were simultaneously tested by using a structural equation model(SEM). The proposed model provided an adequate fit to the data, ${\chi}^2=334.152$ (p<.001), df=162, CMIN/DF=2.063, GFI=.893, AGFI=.861, NFI=.919, CFI=.956, RMSEA=.062. The model's fit, as indicated by these indexes, was deemed satisfactory, thus providing a good basis for testing the hypothesized paths. The SEM showed that relational contract breach (${\beta}=-.236$) had a negative significant influence on job satisfaction. In addition, job satisfaction (${\beta}=-.236$) had a negative significant influence on turnover intention. The moderating effects on career the formulated model was verified. Limitations and future research directions are also discussed.

Since core scholarly journals have been digitalized, license contracts for e-resources have been dramatically increased. Librarians have had difficulties in understanding various and complex license models that are proposed by publishers in a period of time. The standardization of license models for journals have been more in demand and standard model license for journals have been developed by librarians, publishers, consortia and the third party. In this study, we explain the development of the standard license model of KESLI consortium.(hereafter, KESLI model) The availability of KESLI model has been analyzed by comparing with established standard license models. As a result, KESLI model is proved to be adopted and used in a practical contract process of e-journals through consortium.

Notwithstanding the crucial contribution of international construction industry in the national economy, previous studies on international construction contracts had mainly focused either on trend investigation or market share analysis at a point of time. Fundamentally, the international construction industry is fragmented due to its project-based nature, is heterogeneous that has to involve different firms from diverse fields, and tends to be dynamic according to macroeconomic conditions. Therefore, the combination of static and dynamic analyses is necessary to understand its underlying structure. This study analyzes the market structure of international construction contracts using the data of 9,173 projects awarded by Korean construction firms from 2000 to 2017. Industry-level performance data is analyzed both in static (market concentration) and dynamic (market mobility and instability) methods, and detailed methodology is also provided. Consequently, the static analysis result shows that the competition among Korean construction firms has been more intensified, and the dynamic analysis result indicates that market positions of Korean construction firms are unstable and vulnerable in most of the regions and the sectors. The combination of static and dynamic indices is found to be helpful to understand the underlying aspects of market structure and can be utilized as an effective strategic reference in the highly competitive market.
