Interests on Service Level Agreement(SLA), an immanence operating tool for managing the level of the information system service objectively and qualitatively, were raised among IT outsourcing service providers, outsourcers, and operating departments. Yet, only a few domestic conglomerates adopted the SLA, and exact usage of the SLA is currently unknown. Because of the importance of the SLA between a service recipient and a service provider, the agreement is treated with high confidentiality. This raised the problems to organizations which are considering the SLA but lack in the concrete guide line to internalize SLA management process. This study provides the process model of implementation for SLA by conducting multiple case research. The sampled companies are currently implementing the SLA over 1 year of usage period. Factors were used to provide the managerial contribution for implementing the SLA. To analyse the case samples, in-depth interview method was conducted for each sampled company. As a result, if SLA can be used as an immanence managerial tool and can be actively implemented, it will be an strategic tool for various decision making in IT management practice with long term relationship, better shared partnership, and continuous service improvement.

We analyze geological, petrophysical and geomechanical characteristics of a $CO_2$ sequestration test site, Pohang. The target reservoir exists at a depth of 750 m, where porous and permeable sandstones/conglomerates prevail. The reservoir is underlain by thick mudstone formations. We estimate in situ stress conditions using an exploratory wellbore drilled through the target reservoir. The in situ stress condition is characterized by a strike-slip faulting favored stress regime. We discuss various aspects of reservoir fracture pressures and fault reactivation pressures based on the stress magnitudes.

After the publication of the competitive advantage of nations by Porter in 1990, the competitiveness of regional concentrations of industries has been often explained by the cluster concept. There are many definitions of clusters, but they mainly boil down to a geographically proximate group of interconnected companies and associated institutions in a particular field, linked by commonalities and complementarities. The shipbuilding industry in Korea can for sure be regarded as a competitive industry, as the spectacular rise of its world market share from 2% in the early 1970s to the current 38% impressively testifies, but can it be considered a cluster? Based on an analytical framework consisting of a typology of clusters and a context-sensitive evolutionary approach, the paper will show that over the last thirty years Korea's shipbuilding developed from a mere number of isolated, large shipyards (cathedrals in the desert) established by large conglomerates (chaebol) in close collaboration with the central government into an innovative cluster. The cluster is on the one hand characterised by a strongly developed supply industry and specialised universities and research institutes, but on the other hand by a weak, yet increasing role for local and regional institutions The specific and context-dependent characteristics of this innovative cluster are more important explanations for its competitiveness than the financial interventions by the central government, which are repeatedly put forward by European policy-makers in their trade war with Korea.

Using longitudinal data of 575 sample from 122 firms in large business conglomerates from 2001 to 2008, this study examines the impact of controlling shareholders' control-ownership disparity on executive compensation. The empirical study finds that controlling shareholders' control-ownership disparity is negatively related to the level of executive compensation and moderate negatively the relation between firm performance and executive compensation. This finding suggests that controlling shareholders' control rights in excess of ownership rights lead to decreased executive compensation in order to relieve the concerns of stakeholder about the potential agency costs of controlling shareholder, and have, on the other hand, entrenchment effects on the decision of executive compensation by decreasing its sensitivity on firm performance.

The Lago Sofia conglomerates encased in the Cretaceous Cerro Toro Formation, southern Chile, represent a gigantic submarine channel system developed along a foredeep trough. The channel system consists of several tributaries along the trough margin and a trunk channel along the trough axis. Voluminous debris flows were generated ubiquitously along the tract of the submarine channel mainly by the failure of nearby channel banks or slopes. The flows transformed immediately into multiphase flows and resulted in very thick-bedded mass-flow deposits with a peculiar structure sequence. The mass-flow deposits commonly overlie fluted or grooved surfaces and consist of a lower division of clast-supported and imbricated pebble-cobble conglomerate with common basal inverse grading, and an upper division of clast- to matrix-supported and disorganized pebble conglomerate or pebbly mudstone with abundant intraformational clasts. The structure sequence suggests a temporal succession of a turbidity current, a bipartite hyperconcentrapted flow with active clast collisions near the flow base, and a cohesive debris flow probably with a rigid plug. The multiphase flow is interpreted to have resulted from transformation of clast-rich but cohesive debris flows. Cohesive debris flows appear to transform more easily into dilute flow types in subaqueous environments because they are apt to hydroplane. This is in contrast to the flow transitions in subaerial environments where noncohesive debris flows are dominant and difficult to hydroplane.

Global conglomerates in the late 2010s are seeking changes from the existing method of financial growth into that of sustainable growth, as they are facing the age of 4th industrial revolution. In preparation for this change of the times and to stay competitive, small businesses are required to produce creative knowledge, and systematically share and store it by means of implementing voluntary and specific changes in their convictions and actions. This study aims to empirically examine how the ICT small businesses' organizational learning participants' self-leadership affect their job satisfaction through organization orientation and Leader-Member Exchange(LMX). The research sample consists of the first to third-year employees that have previously participated in the small businesses' organizational learning support project, and of learning leaders, group leaders, and group members from companies that have previously concluded the project. The results are as follows: First, the self-leadership at the ICT small businesses' organizational learning project has been shown to have a positive effect on job satisfaction. The same positive results are shown in learning orientation and LMX. Second, the learning orientation has been shown to have a positive effect on job satisfaction. Third, the LMX has been shown to have a positive effect on job satisfaction.

Digestion of primary sludge was conducted to evaluate the effects of reactor configuration using UAD, CUAD, TPAD, and semi-continuos CSTR. Highest VSS reduction and gas production were obtained in CUAD at all HRT. More efficient digestion was accomplished in upflow digesters compared to TPAD and CSTR. Higher thickening of solids in reactor and longer solids retention were main reasons for the enhanced digestion in CUAD and UAD. Performance based on the SRT of CUAD was nearly identical to that of UAD. However, those of TPAD and CSTR were lower than that of CUAD. Particulate and soluble organics in upflow reactors were well adsorbed due to secreted extracellular polymeric substances from the sludge granules. These might result in close proximity of microorganisms and substrates and enhanced hydrolysis. Additionally, diverse anaerobic microorganisms and neutral pH in upflow reactor could induce more activity of hydrolytic enzymes and sludge granules might offer lower thermodynamic energy state. While, excessive mixing in CSTR could break conglomerates of enzymes and substrates into fine particles, which resulted in lowered hydrolysis. Low pH level in acid fermenter of TPAD lowered hydrolysis of the particulate substrates.

This paper has investigated the effects of employees' organizational cynicism on their organizational commitment and pro-union behavioral intentions in the context of repetitively implementing business innovation program. The cynical responses about the business innovation program & projects have been classified into four categories; Exit, Voice, Loyalty and Neglect. The research samples have been drawn from managers and office employees at four business sites of conglomerates in Korea. According to the analysis, business innovation program which is continuous and repetitive has made managers and office employees have highly cynical attitudes. In turn, the organizational cynicism has accelerated their Exit and Neglect responses, but shrunk Voice and Loyalty responses. As a result, it has been confirmed that the organizational cynicism has a direct effect on organizational commitment and pro-union behavioral intentions. In addition, it has been concluded that Exit and Neglect had a negative effect on organizational commitment but a positive effect on pro-union behavioral intentions. Even though Voice and Loyalty had a positive effect on organizational commitment, they had no significant effect on pro-union behavioral intentions. Furthermore, no mediating effect has been detected. Implications and suggestions for future research were then discussed.

The Von Neumann based architecture of the modern computer has dominated the computing industry for the past 50 years, sparking the digital revolution and propelling us into today's information age. Recent research focus and market trends have shown significant effort toward the advancement and application of artificial intelligence technologies. Although artificial intelligence has been studied for decades since the Turing machine was first introduced, the field has recently emerged into the spotlight thanks to remarkable milestones such as AlexNet-CNN and Alpha-Go, whose neural-network based deep learning methods have achieved a ground-breaking performance superior to existing recognition, classification, and decision algorithms. Unprecedented results in a wide variety of applications (drones, autonomous driving, robots, stock markets, computer vision, voice, and so on) have signaled the beginning of a golden age for artificial intelligence after 40 years of relative dormancy. Algorithmic research continues to progress at a breath-taking pace as evidenced by the rate of new neural networks being announced. However, traditional Von Neumann based architectures have proven to be inadequate in terms of computation power, and inherently inefficient in their processing of vastly parallel computations, which is a characteristic of deep neural networks. Consequently, global conglomerates such as Intel, Huawei, and Google, as well as large domestic corporations and fabless companies are developing dedicated semiconductor chips customized for artificial intelligence computations. The AI Processor Research Laboratory at ETRI is focusing on the research and development of super low-power AI processor chips. In this article, we present the current trends in computation platform, parallel processing, AI processor, and super-threaded AI processor research being conducted at ETRI.

The market share of conglomerates is increasing in the Korean school uniform market these days. Functional fit problems occurred. Girls choose slim silhouette often experienced fit problems. The purpose of this study is to probe for functional design elements of high school girls' uniforms. A questionnaire survey was carried out. 202 high school girls took part in the survey. The questionnaire measured school uniform brand preference and size of school uniform jackets. The results of the survey show that over half of participants(56.6%) wore their jackets over nine hours per day. They considered the aesthetics of the design as the most important factor when purchasing school uniforms. That element affected their brand preference. In analyses of the fit suitability, there were no significant differences between brands. The jacket lengths were significantly different among brands, but all were evaluated as being short. About 60% of students had difficulty raising their arms while wearing their school uniform jackets. The results of this study revealed that high school girls' uniform jackets are too short and tight. Ergonomic design elements should be applied to high school girls' uniform jackets.
