This study used a resource-based perspective to analyse the effects of organizational composition on the R&D performance of science and technology government-funded research institutes (GFRIs). We assumed that the composition of each GFRI would eventually be regarded as absorptive capacity and act as a moderating variable between R&D investment and performance. We used a panel generalized least squares (GLS) model with fixed effects to analyse panel data from 115 Korean GFRIs between 2011 and 2015. Our findings show that R&D investment of GFRIs has a direct and positive effect on performance. We also analysed how organizational composition can moderate the effect of R&D investment on performance. The findings provide evidence that organizational composition plays a moderating role between R&D investment and performance. Finally, this study discusses policy implications, its limitations, and also highlights future research directions.

The aim of this study was to analyse the consumer dissatisfaction, complaint and repurchase intentions in foodservices with a particular focus on college students. For this investigation we analysed the responses of 520 college students interviewed from Daegu Gyeongbuk Province. The SPSS/WIN version 12.0 and AMOS version 6.0 were used to analyse collected data. The results were as follows : 1) Factor analysis identified 5 different consumer dissatisfaction factors: facilities, waiter/waitresses behavior, food quality, service, store operating. The level of food quality dissatisfaction was most high. Consumer complaints came in three forms: public, personally and no action. The level of personal complaint was most high. 2) AMOS analysis found that public complaints had the most influence on repurchase intentions. 3) Dissatisfaction was highest with fast food restaurants, which also received the most public complaints. 4) Dissatisfaction, complaints, and compensation strongly influenced eating-out and spending motivation of college students.

P Leasing Company was a steady growing company with positive net income in most years since 1985 when it was established. However, it suddenly experienced a minus net income of 6.8 billion won in 1996. The reason of its deficit was known to be the financial distress of its two major leasing contracts. The total amount of two contracts was 58 billion won witch is about 8% of total amount of its leasing contracts. In this paper, we analyse how the disability of lease payments from the two leasing contracts influence P Leasing Company's financial stability, growth opportunity, and profitability. In addition, by performing ROI analyse, we point out the financial reasons of P Leasing Company's deficit in 1996. We hope our case analysis to help students understand the cash flow of leasing companies. The P Leasing Company case also illustrates the fact that bad leasing contracts would seriously affect the profitability of leasing companies as bad loans would seriously do the profitability of commercial banks.

In the seventh educational curriculum of stage and level education course, the goal of this survey is to analyse the participators' behavior trait changes at the special supplementary course. In order to realize the goal of this survey, I set up the following survey contents. First, to check the responses of participators about the special supplementary course. Second, to analyse the participators' behavior trait changes such as self-consciousness, achievement motivation, learning habit at the special supplementary course.

Safety of Station electric equipment is not analysed yet. this paper try the safety first times on the basis of hazards which railway stations contain. The stations use many electric equipment such as lights, escalator and elevator for facilitating for passengers and public moving, HVAC system making good environment and so on. The electric equipments could be changed to harmful systems to passengers and publics resulting from abnormal operation condition. To ensure safeties in the station, we need to identify and analyse the hazards in the station and to provide risk mitigation methods. In this paper, we shows processes and methods to ensure the safety, how to identify and analyse the hazards. Finally, we demonstrate how to mitigate the potential risks in the stations.

This study contain below two contents. First, this study analyse an effect of consciousness of the quality cost for quality cost activity. Second, this study analyse an effect of quality cost activity for productivity improvement. The empirical result of this study is meaning that quality cost consciousness effects productivity improvement by quality cost activity. Therefore, this paper emphasize consciousness of quality cost for productivity improvement.

Research projects of SNCF aim at reducing the costs of infrastructure possessions and improving the operational equipment availability and safety. This permanent search for a better regularity led the SNCF to analyse the maintenance approach of signalling equipment in detail. Until now, it was commonly acknowledged that signalling equipment, which consists of many electronic devices, is not subject to aging. In this study, a Weibull lifetime model, able to describe an aging phenomenon, is used and it can be shown that the deterioration is statistically significant. The validity of the model is tested. We also analyse the influence of environmental covariates. We simulate different scenarios in order to investigate the impact of several maintenance strategies as well as on future maintenance costs, on the amount of components to replace based on the mean age of the network. It can be shown that in most cases a systematic replacement strategy offers the best solution.

To utilize the Top-Down construction method, it is required to analyse building area, floors, and soil conditions to choose the three basic elements of retaining wall, base column, and floor structure. The purpose of this research is to compare the methods of Top-Down with other construction methods. The research method is to analyse the project conditions of Top-Down project cases. The aim is to develop a method of selecting alternatives, considering construction characteristics, work schedule, supporting methods, foundation types.

A loop power system has a nonlinear characteristics. Also it is very hard to analyse through a equation if a discontinuous characteristic of the ULTC is added to a system. However, the problem which is hard to analyse by equations can acquire the useful result with what use the genetic algorithm (GA) which is a multi-point search program. In this paper, we proved through a simulation that the proposed method can reduce an operation frequency of tap changers and improving the quality of voltage of the buses by decreasing the deviation between the actual voltage and the reference voltage through the coordinated control of the ULTC that use GA in the loop power system.

This paper presents some of the results of current research on 400kN Suspension Insulator Design. In this paper, authors carried out 2-dimensional field calculation in order to analyse dielectric characteristics of the insulator unit and 3-dimensional field calculation in order to analyse dielectric characteristics of the insulator strings. And the results of puncture tests of insulators were compared with the required field intensity of the insulator As results, it was found that electric field on the insulator unit is severest between two triple junctions, dielectric characteristics of insulator strings are much influenced by the surrounding configuration and the manufactured insulators have good results of puncture tests.
