Abstract 논문투고일：2013년 07월 25일 논문수정완료일：2013년 09월 10일 논문게재확정일：2013년 09월 14일* 본 논문은 가천대학교 연구비 지원으로 작성되었습니다. ** 가천대학교 경영학과 교수This paper discussed about creativity and knowledge management variables as for effect factors on the management performance of IT service firms. Specially the mediation effects of knowledge management variables between the creativity and management performance were examined. To prove e mpirically the related hypothesis, the statistical analysis were based on the response from the 160 Korean IT Serv ice firms.As an analysis results, it was found that the creativity of organizations was not the direct effector on the management performance. But the virtue of knowledge which are a ccumulated from knowledge management activity and shared in organizations was the direct effector. Also, the knowledge management activity is mediator on the in the relationship between the creativity and management performa nce. So this paper suggests that knowledge management activity and knowledge’s virtue in the related the c reativity in organizations are the important mediate factors for enhancement of IT service firm’s performance.
Dynamic Permanent Magnet Flux Estimation of Permanent Magnet Synchronous Machines

This paper deals with rotor flux estimation in permanent magnet synchronous motor(PMSM). In most application, the rotor flux linkage is treated as a known constant. However a high operation temperature or a stator winding current impulse may cause magnet flux ripple or demagnetization which has direct impact on machines performance. To estimate the magnitude of rotor flux in this paper Kalman filter is used which chooses stator currents and PM flux as state variables. The estimation method can track the distribution of PM flux correctly and is robust to motor parameters uncertainty. The flux linkage harmonics can be derived from the back EMFs by means of FFT analysis. This method can be used to analyse the magnet flux ripple and demagnetization in PMSM. The simulation and experimental results show the effectiveness of the proposed rotor flux estimation method.
Temporal Stability of X-Band Single-Pass InSAR Heights in a Spruce Forest: Effects of Acquisition Properties and Season

We investigated the stability of TanDEM-X interferometric synthetic aperture radar (InSAR) heights across eight repeated acquisitions. With InSAR height we mean the height above ground of the scattering phase center. We obtained InSAR heights by subtracting a digital terrain model generated from airborne laser scanning. The acquisitions varied in polarization, normal baseline, and season. The study area was a spruce forest in southeastern Norway. We established 179 field plots within 26 selected forest stands and obtained aboveground biomass (AGB) from field inventory. The InSAR heights were generally stable across the acquisitions as was the relationship between AGB and InSAR height, although systematic and random variations were noted. Two acquisitions had close-to-identical technical properties and weather conditions, and they produced close-to-identical InSAR heights. InSAR heights were fairly stable across a range in temperature and precipitation through spring, summer, and autumn, across a range in baseline values and for both HH and VV polarizations. However, a winter acquisition at temperatures of -7°C had much deeper penetration into the canopy and generated considerably lower InSAR heights and, hence, a very different relationship with biomass. Higher random errors were noted in a cross-pol data set due to lower backscatter and when the normal baseline was very small or very large. A height of ambiguity around 20-50 m appeared to be optimal. Interferometric X-band SAR can be used for monitoring coniferous boreal forests as long as the season and technical properties of the acquisition are kept within certain ranges.
A Typology for Service Supply Chains and Its Implications for Strategic Decisions

The strategic management of service supply chains is largely undeveloped despite recent emphasis on service supply chain management as the next frontier of competitive advantage. We propose a new typology for service supply chains that focuses on the service delivery process and is based on two process-related criteria: what is being processed (i.e., people, data, or things) and how it is being processed (i.e., through transforming or transporting). With a focus on the service delivery management process, we compare and contrast the different service supply chains of our typology along four key characteristics: (a) the separability of the customer from the process, (b) the level of customer-induced uncertainty in the process, (c) the importance of providing the customer with physical access to the process, and (d) the type and degree of customer interaction with the process. We discuss managerial implications of these characteristics with respect to the overall strategic focus (cost or differentiation) and outsourcing practices for each type of service supply chain.
Critical Service Encounters: The Employeeâ€˜s Viewpoint (A Study on Restaurant Services in Dhaka City)

The purpose of the study is to evaluate critical service encounter or the critical decisive moment and the customer behavior in those cases. The scope of the study is the frontline employees of different restaurant service industries of Dhaka City. Data were collected using the critical incident technique (CIT), through structured, open-ended questions and the results are content analyzed to examine employeeâ€™s perspective of critical service encounters. The research was conducted over 50 sample units (employees of different restaurants) using the convenience sampling technique. Finally, the study attempted/considered the qualitative data into quantitative analyses. The most notable finding of this research is that employee response to customer need, employee response to service delivery system failures, and unprompted and unsolicited employee action are the critical factor for both the satisfactory and dissatisfactory service delivery in Bangladesh. However, it is learnt from the employee that customers can be the source of their own dissatisfaction through inappropriate behavior. In conclusion, these types of customers are the challenge for the restaurant services including the employees themselves.
Image Processing on Heterogeneous Multiprocessor System-on-Chip using Resource-aware Programming

Multiprocessor system-on-chip (MPSoC) designs offer a lot of computational power assembled in a compact design. The computing power of MPSoCs can be further augmented by adding massively parallel processor arrays (MPPA) and specialized hardware with instruction-set extensions. On-chip MPPAs can be used to accelerate low-level image-processing algorithms with massive inherent parallelism. With the arrival of new heterogeneous MPSoCs, various applications that run on dedicated compute units on humanoid robots like ARMAR, can now be combined and executed on a single-chip. However, the presence of multiple processing elements (PE) with different characteristics raises issues related to programming and application mapping. The conventional approach used for programming heterogeneous MPSoCs results in a static mapping of various parts of the application to different PE types, based on the nature of the algorithm and the structure of the PEs. Yet, such a mapping scheme independent of the instantaneous load on the PEs may lead to under-utilization of some type of PEs while overloading others. At the same time it is difficult to dynamically control and distribute different types of resources among different applications running on a single chip, achieving high resource utilization under high-performance constraints. This thesis focus on investigating the benefits and challenges of using a resource-aware programming model called Invasive Computing for dynamically mapping image-processing applications (used on humanoid robots) to different types of PEs available on a heterogeneous MPSoC named InvasIC. Different types of computer vision algorithms were investigated and implemented on the heterogeneous MpSoC. Based on the new model, the applications can dynamically acquire and release hardware resources, considering the level of parallelism available in the algorithm and time-varying load. Our results indicate that resource-aware programming helps to improve the performance (throughput and worst observed latency) of various computer vision applications along with better overall workload distribution within the heterogeneous MPSoC.
Use of Fly Ash as Soil Amendment for Biofuel Feedstock Production with Concomitant Disposal of Waste Accumulations

Increasingly higher costs of disposal of fly ash (FA) on the one hand, and on the other, the current focus on bioenergy offer opportunities for using FA as soil amendment for producing biofuel feedstock while cleaning up accumulations of the product. Greenhouse pot experiments were conducted in a silt loam soil amended with 0%, 2.5% and 20% FA to determine boundary shoot and root biomass productivity by the cellulosic herbaceous perennials (CHPs) switchgrass (SG), eastern gamagrass (GG) and big bluestem (BB) grown at pH=4.5 and 6.5. After three months of growth at pH=4.5, shoot biomass productions was generally in the order SG>GG>BB. Root biomass was slightly different and it was in the order SG=GG>BB. Soil amendment with 2.5% FA did not affect biomass production either CHP; however, biomass production at 20% FA amendment declined in all cases. Results for SG and BB only evaluated at pH 6.5 were similar to those at pH 4.5. Needs were identified to define optimum levels of FA amendment to add to soil and combinations of FA and organic amendment that could enhance simultaneous utilization of FA and biofuel feedstock production.
Importance of steak origin to restaurant customers

Today, consumers are more informed about the origin of their food due to the desire to have confidence in the safety of their food. This need for information has lead to an increase in demand for even higher levels of safety and quality (Unnevehr, 2003). Currently, traceability and source-verification are considered indicators of beef quality and safety by consumers. Mennecke et al. (2007) found that consumers place a high precedence on any information that can relate to the origin and production of their food. Research also indicates there could be preference for U.S. beef, especially beef from the Midwest (Mennecke et al., 2007).
[The role of airway neurogenic inflammation in gastro-esophageal reflux induced cough].

OBJECTIVE To investigate the role of airway neurogenic inflammation in the pathogenesis of gastro-esophageal reflux induced cough (GERC). METHODS Sputum was induced by hypertonic saline aerosol inhalation in 20 patients with GERC (GERC group), 10 healthy subjects (normal control group) and 8 patients with chronic cough due to other causes but complicated with gastro-esophageal reflux diseases (GERD, GERD group). Airway mucosal biopsy was performed in 6 patients with GERC and 4 patients with GERD using flexible fiberoptic bronchoscopy. The expression of substance P (SP), neurokinin 1 receptor and neurokinin A (NKA) in sputum cells and airway mucosa were detected by immunohistochemistry, and was assessed semi-quantitatively. SP, NKA, and NKB in the supernatant of induced sputum were measured with enzyme linked immunosorbent assay. Calcitonin gene-related peptide (CGRP) was measured with radioimmunoassay. RESULTS The concentration of SP in the supernatant of induced sputum was significantly higher in GERC group [(266 +/- 207) ng/L] than those in normal control group [(143 +/- 36) ng/L, P < 0.05] and GERD group [(130 +/- 11) ng/L, P < 0.05], and the sputum supernatant concentration of CGRP in GERC group [(180 +/- 83) ng/L] was significantly higher than those in normal control group [(105 +/- 64) ng/L, P < 0.01] and GERD group [(89 +/- 16) ng/L, P < 0.01]. The expression of SP, NK-1 receptor and NKA in induced sputum cells in GERC group were significantly higher than those in normal control group (P < 0.01, < 0.05, < 0.05) and GERD group (all P < 0.05); Expressions of SP in airway mucosa was significantly higher in GERC group than in GERD group (P < 0.01). After treatment, the concentration of CGRP in the supernatant of sputum in GERC patients was significantly lower than that before treatment (P < 0.05); the expression of SP, NK-1 and NKA in the induced sputum cells were significantly lower than that before treatment (P < 0.01, P < 0.01 or P < 0.05). CONCLUSION There is airway neurogenic inflammation in GERC patients, which maybe closely related to the development of GERC.

News consumption in an age of mobile media: Patterns, people, place, and participation

Having a mobile device continuously within an arm’s reach has changed everyday life. A retrospective glance shows that the mobile phone has enjoyed a broad diffusion around the globe during the 1990s and 2000s. This development has made possible mobile communication at any time and any place. Functioning as a tool for interpersonal communication—via voice calls and texting—it has become a taken-for-granted part of everyday life (Ling, 2012). Until recently the diffusion of mobile phones was twice as high as the diffusion of Internet access, but with mobile phones having become equipped with Internet functionality this gap is losing its relevance. Feature phones have increasingly been displaced by more and more smart mobile devices equipped with advanced hardware and software that facilitate not only communication but also the production and consumption of media. These personal and portable mobile devices provide ubiquitous connectedness through computer-like functionalities. Facilitated by developments of computing and hardware, they offer a touchscreen interface to a mobile ecosystem loaded with customized applications and responsive sites. Alongside these we also find that tablets have gained significance, offering largely similar affordances (although typically not traditional voice calls), but with slightly larger screen sizes. Situated betwixt smartphones and tablets one finds phablets offering affordances from each category that thus blurs the boundaries further. All of these mobile devices offer instant and personalized access to search engines, social networking sites, games, news, etcetera. Ultimately there has been a tremendous shift from mobile handsets designed primarily for communication toward more versatile media and communication functionalities. Legacy telecommunication equipment suppliers such as Ericsson, Nokia, and Motorola have struggled in making the shift, and have all suffered market share losses before being taken over by competitors. It is not only the telecommunications industry that has seen

Investigation of institutional investors’ responsible investment practices in UK

The focus of Corporate Governance is shifting from the role of directors to active ownership. Based on their fiduciary duty to other shareholders, it is believed that institutional investors have an important role to play in this regard. However, the Pension Funds and the Sovereign Wealth Organisations are not driven by the same set of objectives. In addition, Environmental Social and Governance (ESG) issues in investment decision-making are now becoming more important and they are capable of becoming the mainstream in the future. However, there are widespread variations in perception of fiduciary responsibilities, ESG issues appraisal, as well as the strategies adopted by institutional investors on shareholder engagement as responsible investors. Responsible Investment market is largely driven by institutional investors and they are expected to continue to lead the way. This research work investigates the role of the main asset owners and their advisors in responsible investment practices in the UK. It adopts a qualitative approach using semi-structured interviews, questionnaire and meetings observations. Gathered data is analysed using grounded theory and the findings highlight the perception of the various investor groups to corporate governance. The research work contributes to the body of knowledge by assessing the corporate governance perspectives of the various classes of institutional investors which may have practical implications for other countries.
Ascending Meningitis Secondary to Traumatic Cerebrospinal Fluid Leaks

Cerebrospinal fluid (CSF) leakage may cause immediate or delayed complications, such as ascending meningitis and brain abscess, potentially lethal complications that may appear years or decades after the trauma. Thus, the initial treatment of a CSF fistula may decisively influence long-term outcome. In a retrospective study including 1036 consecutive patients presenting with severe cranial trauma from May 1990 to March 1996, we identified 27 patients (2.6%) with CSF fistulas. Patients with a post-traumatic CSF leak were most commonly males between 15 and 40 years involved in a motor vehicle accident. The most common sites of injury were the frontal area and anterior skull base for those patients with rhinorrhea and the temporal bone for those patients with otorrhea. A transcranial repair was used for large cranial base defects (n = 10), while conservative treatment, comprised of bedrest, lumbar drainage, and medications, was used for smaller fistulas (n = 17). Four patients (40%) initially treated with a transcranial repair, and five patients (29%) initially treated conservatively, developed a meningitis. Therefore, neither the conservative approach nor the transcranial repair was able to prevent this considerable incidence of ascending meningitis. We believe that the high incidence of meningitis is not acceptable; thus, we are now evaluating early intervention using endoscopic techniques for the identification and/or repair of post-traumatic fistulas.
A Model for Predicting Advertising Quality As a Key to Driving Sales Growth

ABSTRACT The current research used McDonald's data to explore the relationship between advertising quality and sales growth. Based on a 6.5-year dataset involving more than 180,000 consumer interviews, the researchers found that nearly half of McDonald's sales growth could be explained by variables related to advertising quality. Specifically, the study found that factors such as sales momentum, the introduction of calorie content on to quick-service restaurant (QSR, i.e., fast-food) menus, and variables related to key research metrics—and, importantly, the right messaging strategy—can be effective in linking advertising to variation in sales.
The Role of Advertising in the Adoption of Industrial Goods: A Look at the Raw Materials Industry

Abstract Although there is comparatively little money spent annually on industrial advertising, several studies have indicated its effectiveness and efficiency during the early stages of the industrial adoption process. This paper examines the comparative effectiveness of five promotional tools in the marketing of an undifferentiated industrial good. Within the cognitive—affective—conative adoption framework, this paper analyzes the role of both personal and non-personal media in the marketing communications process. The results of the study have application for both industrial advertising practitioners and communications researchers.
THE ECOLOGY OF FERTILIZATION OF ECHINOID EGGS: THE CONSEQUENCES OF SPERM DILUTION, ADULT AGGREGATION, AND SYNCHRONOUS SPAWNING.

Percent fertilization of eggs of the echinoid Strongylocentrotus droebachiensis (O. F. Müller) was determined both in laboratory and field experiments. In the laboratory, over 50% of the eggs were fertilized only in relatively dense sperm suspensions (> 106 sperm/I); such suspensions retained their potency for less than 20 minutes. In the field, divers induced individual S. droebachiensis to spawn with KCl injections. Along five meter transects running directly downcurrent from spawning males, fixed volumes of seawater presumably containing sperm were drawn into syringes already containing eggs. Within 20 cm of spawning males 60-95% fertilization usually occurred; at distances greater than 20 cm less than 15% of the eggs were fertilized. Higher percentages of eggs were fertilized when current speeds were low (<0.2 m/s); swifter currents quickly diluted sperm so that little fertilization occurred. When several males were induced to spawn synchronously, percent fertilization increased but was generally less than 40% at distances greater than 2 m downstream. These results indicate that production of zygotes could be much less than production of eggs. Life-tables based on estimates of egg production may then be in error, unless adults aggregate and spawn synchronously, countering dilution of sperm by currents.
Papilloma-like virus from bovine urinary bladder tumors.

Summary Suspensions of 6 spontaneous bovine urinary bladder tumors produced fibropapillomas of the skin and vagina as well as polypoid growths with fibroma in the urinary bladders of test calves. The induction period ranged from 25 to 111 days. Three serial animal passages of one isolate which was filterable did not increase the activity of the virus. The infective agent resembles the bovine wart virus in its behavior in test calves and may be a causative factor in the etiology of spontaneous bladder tumors or it might simply be a passenger virus. Material from 10 other spontaneous bovine urinary bladder tumors were inactive.
Risk communication,Trust in government and Consumers' recovery behavior——A Case Study of the Melamine Incident

Using data collected from a consumer survey in Shijiazhuang and Baoding,Hebei province, this paper analyzed the relationship between"consumers' trust in the information provided by government"and "dairy consumers' recovery behavior" after the Melamine incident. A preliminary framework of risk communication between government and consumers was constructed in the context of food safety incidents. The instrumental variable Tobit model was estimated to solve the endogenous problem caused by the core variable "consumers' trust in the information provided by government". The results showed that the increases in consumers' trust in government would significantly improve the level of purchase recovery,which implied that the risk communication played an essential role during the food safety crises.
