According to establishment of WTO, the international organizations such as ILO, DECD accelerate the laws and rules to control some countries which persue their own interest and settle the free trade system simultaneously. Therefore, each country is trying to build its responsiveness and fortify the competition of company through the promotion of productivity and product quality. To response actively in these streams, we have to establish the adequate management policy and the safety and health management in our companies. It makes the level of international competition of the companies higher. In this paper, we developed the SMI(safety management index) program by the computer language with algorithm of safety management certification to assist the activity of safety management. It makes the operating of the safety management assess more detail through quantitative methodology and provide the convenience in analyzing their safety problem.

Productivity improvement of manufacturing industry has been the primal engine of the national economic growth. The primal objective of this study is to investigate the productivity performance of the Korean manufacturing industry for the past two decades. Tornqvist discrete approximation is used to calculate productivity growth rate and factor contributions to the economic growth from labor and capital input. The empirical results showed that the productivity growth has not been the major contributing factor in the growth of the Korean manufacturing industry for the past two decades. We also investigate the relationship among productivity growth rate, R&D, and information technology. With a simple regression approach, we found that R&D has resulted in the positive effect on the productivity growth, while expenditure on the information technology has not provided noticeable positive effect. From the empirical results, we know that more attention should be focused on the environment or infrastructure in which the information technology is used rather than on the absolute size of the expenditure on the information technology.

This paper presents a recurrent neural network model which takes outputs of a hidden layer of multilayer neural network (MNN) as inputs. The proposed network model has a context layer for taking input streams out of the hidden layer. We have proved that the proposed recurrent neural network (RNN) model should be a generalized form of nonlinear autoregressive moving average (NARMA) model. We have tested performances of the proposed method for a few time series data. The prediction performances of the recurrent neural network model are shown to be competitive enough for a general predictor.

This study investigates the relationship between attitudes toward the introduction of teleworking and seven components of organizational culture: digital acceptance, latitude, openness, creativity, global mind, sympathy, ideologization. The Korean companies we study equiped their managers, professionals and salespeople with advanced computer-based technologies for the introduction of teleworking. Besides the aspects of economy and productivity, this study focuses on organizational culture and employees` attitudes with respect to the introduction of teleworks. The introduction of teleworking requires more self-organized and self-motivated support from employees. The rapid change of working life and with it new forms of work like teleworking not only gain in attractiveness, but also they are increasingly offered to people who, are not yet ready for the new message. The relationship between attitudes toward the introducing teleworks and components of organizational culture was tested through correlation analysis. Digital acceptance, global mind, openness, creativity and ideologization correlates positively with positive attitudes toward the introduction of teleworking. Telework may be accepted by many companies, but many respondents of this study are resistant to the idea of invisible employees, even if productivity does shoot up in many cases. Telework in particular is associated with high hopes, yet hardly anyone today knows exactly what future work with a large proportion of teleworkers will look like or ought to look like.

They say Japanese die & mould industry has superior technology competitiveness. What makes Japanese industries so excellent? On this study, I tried to analyze these factors that have been helping Japanese die & mould industry to improve their technology competitiveness. First, Japan has acquired a high-level technology and an advanced production equipment, centering around NC machine tool, CAD, CAM. And it also has developed and accumulated its skill to manage these a high technology and an advanced production equipment. Secondly, There are the connected industries with die & mould, such as basic materials industries, machine tool industries and supporting industries. In Japan, these connected industries have been developed highly and have had great influence on developing die & mould industry. Third, Japanese die & mould industry have been making a speciality of itself only. It has also built up the pyramidal division of technology. Under the influence of these two factors - the professional production style & the pyramidal division of technology -, Japanese die & mould industry have been made up its technology competitiveness.

It is very difficult to control properly the demand and supply of fishery having great dependence on the natural conditions. And fishery has to go through the complex marketing process varying from place to place to reach its final consumers. The each year increasing amount of fishery, however, has a great portion of the nation`s economy now and affects the consumer price in general, which requires the current its marketing system to be improved. Therefore, this study suggests a new model of marketing structure based on the analysis of current marketing practices, which, I hope, will give a momentum for the more advanced marketing industry of fishery. The study employs the method of questionnaire for brokers, wholesalers in metropolitan areas and consumers and proposes; with the results of the factors analysis, a model of improved fishery marketing structure is given. In conclusion, the study proposes a marketing structure where the consumers can buy fishery in brokers excluding the mid marketing and those concerned can share the information necessary to get the structure going normally. It is necessary, however, that the steady supply of fishery and computerized system of marketing informations should precede other things to guarantee the improved wholesalers` market for the consumers.

The economic crisis in Korea known as IMF bailout in 1979 produced a vast number of layoffs as the consequences of restructuring. During these gloomy three years there is, however, one man who got transferred to the headquarter of bank with a promotion notwithstanding the overwhelming number of laid-off colleagues in the name of `honorary retirement`. The principles governing this man`s life was an attitude of `New Elite` (shin-jishi-in) even before the term was coined in Korea, and he has been practicing `knowledge based management` long before the term was available in Korean society. Based on the case study of the manager K of KFB in regard to `knowledge based management` style, this paper probed some ways how Korean financial industry can be a strategic industry which can produce higher economic value added. The things he initiated to actively cope with the ever changing business milieu are as follows: he has made use of bank cafeteria as a virtual place for English practice space; setting up an exclusive consultation window for customers to assist financial consulting service; opening cyber space to customers in the changing clime of digital time. By adopting a several rules he created such as a `stewardship management practices`, a policy of positive problem solving, and a rule of creative effort, he has not only shown some suggestion for a new vision in business but was able to get a high achievement through customer-first management, close field management, and soliciting voluntary participation of the whole staff. The management paradigm of manager K of KFB can be summed up as strategic management, knowledge based management, field management, and participating management.

This research investigated the mediating role of organizational commitment on the relationship between supervisor commitment and effectiveness. Correlation and mediating regression were employed to test the hypotheses. The mediating role of organizational commitment was examined using Baron and Kenny`s approach. With 3,200 members in a securities company, it was found that (1) organizational commitment is a mediator in job satisfaction and intention to work and (2) direct relationship between supervisor commitment and two dependent variables is also revealed. Some implications of these results are discussed.

The purpose of this study is to investigate the risk management of finacial institutions by using VaR(Value at Risk) method. It was analyzed and compared with differences between the real profit-loss amounts calculated by using data of 1997 one year and VaR estimates investigated by using data of 3 months(72days) derived from Jan, 1998 to March 1998. VaR estimates was derived from three VaR methods, as the time weighted average method, MonteCarlo simulation method and historical simulation method. The empirical results are as follow: First, we found that in case the real values exceed expected loss amounts at the 95% confidence level, the lowest error rate came out when λ=0.99 of time weighted average method. These results may imply that in case weighted values allow at the nearest data more than past data, the expected excess days decrease in the time weighted average method. Second, empirical result proved that MonteCarlo simulation method with the lowest error rate had most smallest mean of bias in the significance test between the real observation values and VaR values. These results may imply that time weighted average method is suitable in order to manage the situation being placed in extreme financial distress situation and MonteCarlo simulation method is suitable in order to minimize the opportunity cost according to retention of reserve money caused the loss. Specifically, we found what the financial institutions dealing with money goods and derivatives responding sensitive to price volatility risk and credit risk should be managed the integrated risk management. We may suggest financial institutions could use effectively the market risk values estimated by VaR method for risk management.
