We have examined and analyzed the status of policy, R＆D investments, patents and market share of physiological signal measurement technologies for major countries including Korea, the United States, European Union and Japan. Korea is generally inferior to the others in terms of priority of industrial policy, R＆D investment, number of patents, technological level and world market share. However, Korea could recover competitiveness, with intensive government supports for this technology.

The purpose of this study is to explore self-directed learning (SDL) in the workplace and to examine labor education in South Korea in order to draw the critical implications for legislation on trade union education (TUE). First, labor education in South Korea and its legal system were reviewed in a detailed way. Second, SDL in the workplace was closely analyzed from the perspectives of not only human resource development (HRD) but also adult education and lifelong learning. Third, based on the results of the comprehensive review, the implications of SDL in the workplace for worker-initiated labor education were discussed in terms of legislation on TUE in South Korea. Since legislation at the national level can promote workers' participation in TUE in the context of SDL for industrial democracy, TUE in South Korea should be provided with appropriate legislative, financial, and administrative support.

Britain's public services, especially health service and secondary education are in disarray. The current British government adopted the public-private partnership(PPP) as a major device to bring about public sector reform. In principle, PPPs could be used to outsource all sorts of public services, helping to raise standards by extending choice and competition. Up to now, however, they have been focused mainly on a relatively limited range of ancillary services related to new buildings and their subsequent operation. The unions, especially the unions covering the public sector employees are antagonistic to the PPPs. The unions have been opposing privatizing or resecting of any part of the public services, as these apt to lead insecurity of employment and degradation of working conditions of their members. Most of the union leaders consider that PPPs are 'privatization by stealth'. Even in Britain, which has a long history of trade union movements, to persuade the unions to co-operate to the reform policy has been extremely difficult. To succeed in public sector reform, the government, be it Korean or British, needs strong leadership, consistency in policies between various departments, and persuasive ability to overcome the opposition from the vested-interest group.

The university course scheduling problem (UCSP) aims at optimally arranging courses to corresponding rooms, faculties, students, and timeslots with constraints. Previously, the university staff solved this thorny problem by hand, which is very time-consuming and makes it easy to fall into chaos. Even some meta-heuristic algorithms are proposed to solve UCSP automatically, while most only utilize one single algorithm, so the scheduling results still need improvement. Besides, they lack an in-depth analysis of the inner algorithms. Therefore, this paper presents a novel and practical approach based on Tabu search and simulated annealing algorithms for solving USCP. Firstly, the initial solution of the UCSP instance is generated by one construction heuristic algorithm, the first fit algorithm. Secondly, we defined one union move selector to control the moves and provide diverse solutions from initial solutions, consisting of two changing move selectors. Thirdly, Tabu search and simulated annealing (SA) are combined to filter out unacceptable moves in a parallel mode. Then, the acceptable moves are selected by one adaptive decision algorithm, which is used as the next step to construct the final solving path. Benefits from the excellent design of the union move selector, parallel tabu search and SA, and adaptive decision algorithm, the proposed method could effectively solve UCSP since it fully uses Tabu and SA. We designed and tested the proposed algorithm in one real-world (PKNU-UCSP) and ten random UCSP instances. The experimental results confirmed its effectiveness. Besides, the in-depth analysis confirmed each component's effectiveness for solving UCSP.

As the number of end-of-life vehicles (ELVs) has kept increasing, the management of ELV has also become one of the academic research focuses and European Union recently adopted the directive on ELVs. For the stakeholders has become a principle agent of dealing with all about ELVs, it is relevant investment decision to set up and to decide high-cost ELVs entity locations and to forecast future ELVs' amount in advance. In this paper, transition probability matrixes between months are made by using Markov Chain and the number of ELVs is predicted with them. This study will perform a great role as a fundamental material in Korea where just started having interests about recycling resources and studies related to the topic. Moreover, the forecasting method developed for this research can be adopted for other enhancements in different but comparable situations.

For VBR video traffic, Motion-Picture Experts Group(MPEG) coding algorithm was adopted as the standard coding algorithm by International Telecommunication Union(ITU). In this paper, we propose a traffic model of an MPEG coded video traffic in frame level and cell level, and develop an approximate model for evaluating performance of a ATM multiplexer with homogeneous MPEG video sources by considering burst-level variation of aggregated traffics. For homogeneous MPEG video traffics which are frame-synchronized, the performance of the ATM multiplexer is influenced by source correlation at the multiplexing time. When sources are highly correlated, we decompose the aggregated cell streams by the frame-type and model multiplexing process during a frame time as n*D/D/1/K queueing model and suggest an approximate method for obtaining CLP of the ATM multiplexer. In the case that sources are highly correlated, the solution has the meaning of the upper bounds of performance of the ATM multiplexer. For the verification of our model, we compare the solution of our model with simulation resets. As the number of sources increases. The CLP obtained from our model approaches to simulation results, and gives upper bounds of simulation results.

Sediment samples from five stations at the Shihwa Lake sewage outfall, west cost of Korea, were collected to evaluate the effect of the outfall on benthic foraminifers. Heavy metal (Cu and Zn) polluted the eastern part of the Shihwa Lake, adjacent to the Shihwa-Banwol Industrial Complexes, shows barren or nearly barren of benthic foraminifers, and the lowest number of species both at the core top and downcore. Excepting for the barren zone, pyritized benthic foraminifers abundantly occur both at the surface and downcore sediments in the western part of the Shihwa Lake, suggesting that foraminiferal disease by anoxic bacteria. Recent intrusion of pollutants form the Shihwa-Banwol Industrial Complexes and adjacent six major streams severely polluted the Shihwa Lake as shown by the low abundance (number/10 g) of benthic foraminifers, low number of Ammonia beccarii, low species diversity, and absence of both Elphidium spp. and ostracodes at the surface sediments compared of both downcore. Except the barren zone, both pyritized and non-pyritized Ammonia beccarii occur dominantly in the surface sediments and downcore. Elphidium spp. (either pyritized or non-phyritized) do not occur in the surface sediments of whole stations. However, they occur from the entire downcore sediments except in the eastern part of Shihwa Lake. Arenaceous foraminifers do not inhabit in the heavily polluted areas as evidenced by the occurrence of relatively deep core depth (11-15 cm). Ostracodes occur at the downcore sediments, but they do not occur at the surface sediments. Ostracodes also do not occur at the heavily polluted areas in the eastern part of the Shihwa Lake both at the surface and downcore sediments, indicating that the abundance of ostracodes also can be used for a pollution indicator.

The end of cold war and the trend of the detente brought about many changes in the military security policy and in the munitions industry of the West-Europe : reduction of the defence budget, diminution of the military power force and armaments, decrease of the exportation and the domestic demand of ordnance, and augmentation of discharged laborers. This mutation caused the munitions industry and the war industrials regions to a crisis. The munition industrials enterprises which was confronted a crisis searched for diverse strategies like an reconversion to the civil products, an internal diversification and an external growth. And the European Union, the national government, and local or regional self-government implemented policies for diversification of regional economic with an reconversion in order to minimize the effect of the regional economic and society from the crisis of the munition industry.
