Information and communication technology (ICT) has been recognized as one of the alternative source of productivity growth and, in turn, economic growth. However, there has not been much literature reporting that the benefit of ICT has materialized in countries other than United States. Since the Korean economy has allocated a large amount of resource to develop ICT capacity after the mid 1990s, it is time to investigate whether the invested resource has done something to boost the productivity. This study performs various regressions to analyze the relationship between ICT and productivity at the sectoral level. The basic methodology relies upon the framework developed by Griliches in the field of R&D. The study also examine the causality among ICT, R&D and industrial productivity based on the time-series analysis. The empirical results show that the ICT has not provided much positive effect in productivity improvement so far, and more attention should be paid to the efficient utilization of invested capital.

We detect lots of problems on the manufacturing spot because of working results done without considering the aptitude and inherited temper(constitution, blood type, male and female) of the worker, and they lead to results not only the occupational disease and the cause of industrial accidents but also quality deterioration and productivity reduction in point of view of manufacturing management. For the purpose of solving these problems, this study is performed by grasping the correlation sasang constitutions and job characteristic of small & medium enterprises. We classify sasang constitutions to four types : so-yang-in type, tae-yang-in type, tae-em-in type, so-em-in type by the utilization of QSCC II and the doctor aid of oriental medicine. This study tries to identify significant features between major jobs resulting from sasang constitution types in a specific small & medium enterprise producing electronic productions(CCTV). The results of this case study indicated that sasang constitution types influenced job types. Under the working conditions that virtual reality scene photographed by video camera are running, also the effects of brain function of each worker using Electroencephalograms(EEGs) are investigated. An statistical analysis of experiments conducted shows the various changes of brain waves (α, β, θ, δ waves). By means of these study results, we can identify that sasang constitutions should be applied to contribute much to quality advancement and productivity improvement through a comparative study on the job characteristic.

The business ethics of managers is very important in the production of manufactured goods and service. First of all, managers must stand at the head in the quality for the first of quality plan in management. When workers take part in as having a voice in the management, thinking a business and products of one`s own self, the quality and the service improve, customers will be satisfied. As doing so, the business ethics and improvement of quality carry out the productivity, we can realize making a contribution to the cost redution and making a good profit. A manager and a worker must hear the need and the demand at a side of customers, also must manufacture and service as the sprits of a workman with consciousness of moral and ethics.

Many domestic companies have been acquired the ISO 9000 series certification ever since the quality assurance system of ISO(International Organization for Standardization) 9000 series introduced. This certification system means that a company can satisfy the minimum requirements for the quality assurance. And, eventually, ISO 9000 series is understood as quality assurance system for product by customers. A purpose of this study is to analyze the degree of product`s quality improvement and productivity improvement by the effectiveness which is identified as worker`s mindset improvement, a management ability improvement and quality system`s establishment in the existing papers as well as the construction of a quality assurance system by acquiring the ISO 9000 series certification. In order to identify the product`s quality improvement and productivity improvement, the analysis of a design quality improvement, a manufacturing quality improvement, a service quality improvement, and productivity improvement are conducted through this study.

In this study, I analysed the effect of the Korean Export Insurance System upon Productivity Improvement for Korean Export Industry, investigated Korean Export Insurance system since Korea Export Insurance Coporation(KEIC)`s establishment and sought for the measures overcoming problems therewith. In my research I started from a basic model analyzing Korean Export Insurance System using added several variables that have effect on export such export relative price, world income and the amount of export insurance As a result, amount of export Insurance and world income showed expected responses and the coefficients were generally significant but export relative price were no statistical significance. In case of amount of export Insurance, however, there was statistical significance.

The study is intended primalily to explore the procedures of the licensing contract and censorship for the foreign produced video programs. In detail, two stages in the whole procedure for releasing the program are main concerns. The first stage is to make a contract with a licensor after scrutiny of programs. It could be turned out whether or not the program will be successful depending on making a good choice of the program and a thorough making out of the contract. The second stage is to require a primary censorship to Korea Censorship Association in which to investigate and judge the degree of obscenity and violence applying the Law of Phonogram and Videogram on it. The program may receive it as a social valuation in the import country in this stage.

The purpose of this study is to analyze and implementation of the extract evaluation system about literary works. Recently, many literary works is copied by illegal, but there is no measure unit about it. The degree of extraction is evaluated by its key word in some of literary works, but it is impossible to measure its degree of extraction exactly. This study implemented evaluation system to measure the extract status of literary work using by how to block binary file and its algorithm. Follow the next step. Step 1: Select two files (source file, target file) Step 2: Block files with specified size. Step 3: Search source block in target file. Step 4: Calculate the rate of extract Step 5: Group the similar literary works. Step 6: Report The results are expected to provide the information of extract degree in literary works. However, this study has several limitations. First, it takes long time to compare files. Second, this study has many meaningless blocks in files. Therefore, hereafter, literary works must be clustered with a kind of its and we will need searching for meaningless blocks.

This study examined the information effect of stock option on stock price in Korean Stock Exchange(KSE) and Korea Securities Dealers Automated Quotation (KOSDAQ) over the periods from 1997 to June 2000. The result confirms that even though the information effect of stock option is positive in both KSE and KOSDAQ, the size of effect in KOSDAQ is greater than that in KSE. This means that when the growing firms like venture companies endow the stock option to recruit promising employees or motivate managers, the effect of stock option endowment on stock price will be greater through the increase of productivity. Because the returns during announcement period (two days` returns before and after the announcement date) is less accurate than the return on the announcement date, the event study, using daily return on the announcement time, is more appropriate, as long as the exact time of the formal announcement to endow stock option. is known to the public,

Empirical research in finance over the past two decades has uncovered three major findings with respect to cross-sectional return predictability : reversal at short horizon, momentum at intermediate horizon, and reversal at long horizon. This article examines whether a simple accounting-based fundamental analysis strategy, when applied to a broad portfolio of past performance or expected performance, can shift the distribution of return earned by an inverstor in Korean stock market. We start with simple one-variable classifications of past winner and loser stocks that rely in most cases on measures of either past performance or expected performance. We then move on to classifications in which loser or winner is defined using both past performance and expected future performance. The sample period is from 1992 to 1996. We formed portfolios every year starting at the end of January 1992 and we examine subsequent performance for up to 1-year after formation using return data from Korea Securities Research Institute-Stock database(KSRI-SD) and accounting data from Korea Investors Service-Financial Analysis System(KIS-FAS) Database. In conclusion, we find average negative performance of investment strategy based on one-accounting variable. And we find average negative performance of investment strategy based on double-accounting variable, too. In particular, when portfolio is formed using past growth sales rate as past performance and past earnings to prices, cashflows to prices as expected future growth, we find a strong and persistent negative performance of zero-cost portfolio. Finally, negative performance of one-variable investment strategy using past five-years growth sales rate generates rather on the sell side than on the buy side. But negative performance of double-variable investment strategy using past growth sales rate as past performance and past earnings to prices, cashflows to prices as expected growth are not generate either buy side or sell side.

The purpose of this study is to provide the basic data of the evaluation methodology in order to apply the ergonomic program for industrial workplace. The result is helpful to establish the improvement alternatives that considered the assessment tools suitable work characteristics in order to prevent musculoskeletal disorders in workplace. We analysed the collected data of workers complaining of musculoskeletal-related pains during 4 months using musculoskeletal administration program(WinCare). As the results, the pained workers had mostly a pain in low back. The results showed that the pained workers in the automotive manufacturing industry pained in several body parts because they worked using the whole body. Also, most of pained workers in the electronic industry and the other industry pained respectively in the upper limb and low back related heavy load handling. That is due to difference of body parts used in each industry. The approach of this study will help to more precise assessment of the ergonomic work postures when establishing the ergonomic improvement plan, especially to consider the application method to workplace using the suitable ergonomic assessment tools classified by type of industry.

This paper estimates information and telecommunication (IT) capital stocks by industrial sectors in Korea for the period of 1985∼1999. This would be the first time to estimate IT capital stock at this sectoral level. The definition and classification of IT capital is based on the `Report on the Information and Telecommunications survey` published by National Statistical Office of Korea. Investment series are estimated from input-output tables published by the Bank of Korea. The resulting series show that the rate of IT capital stock accumulation during the study period has been faster than that of total capital stock by 10.8% during the same period. The sector which has had the highest growth rate of IT capital stock turns out to be the electricity and telecommunication sector. This study also analyzes the relation between IT capital stock and the labor productivity based on the estimated capital stock. In general, the IT stock has positive impact to improve labor productivity. However, the degree of this relationship differs from industry to industry depending upon the industry characteristics. Especially, in service sectors, so-called productivity paradox regarding IT investment may occur. Some policy issues are dealt with at the end of the paper.

This research investigated the moderating role of career-related characteristics on the relationship between job characteristics and organizational citizenship behaviors. Correlation and hierarchical regression were employed to test the hypotheses. The moderating role of career-related characteristics examined using Baron and Kenny`s approach. With 3,200 members in a securities company, it was found that (1) job characteristics are positively related with OCB and (2) Career-related characteristics are partial moderators in the relationship between job characteristics and OCB. In particular, age, rank, and job seniority have been investigated as moderator. Some implications of these results are discussed.
