Eco-labelling programs contributed to the promotion of international trade of environmentally friendly products. However, it has potential trade implications. From the WTO's point of view, environmental measures relevant to eco-labelling should not discriminate between home produced goods and imported goods. Transparency should be guaranteed in preparation, adoption and application of eco-labelling. Developed countries address that eco-labelling of non-product PPM criteria is included in the provisions of TBT of WTO. However, there are more general afraids that non-product PPM-based eco-labelling can be unfairly discriminately trade measures without transparency Thus, transparency of procedures of eco-labelling, harmonization and mutual recognition of eco-labelling criteria, and technical assistance should be recommended in order to reduce trade-discriminating effects of eco-labelling.

Cleft lip and palate is a congenital deformity which needs a professional and consistent management from the birth and along with the physical growth of patients. The patients with cleft lip and palate can have general speech problems with resonance disorders, voice disorders and articulation disorders after the successful primary surgical management and the physical growth. Speech problems of Cleft lip and palate are characterized hypernasality, nasal air emission, increased nasal air flow, and aberrant speech marks which decrease intelligibility. These speech problems of cleft lip and palate can be treated with the secondary surgical procedure, the application of temporary prosthesis and the effective and well-timed speech therapy. The speech and language problems of cleft lip and palate, the general procedures and schedules of the speech assessment and therapy based on the multidisciplinary approach are introduced for the patients with cleft lip and palate, their family and the other members of the cleft palate treatment team.

This paper is concerned with a six sigma application to non-manufacturing process. Based on the comparison to manufacturing process, non-manufacturing process has some specific characteristics. The main focus of this study is to introduce an empirical case study on the implementation of DMAIC procedures for non-manufacturing process. We use a simple and practical road map which consists of 13 steps. Some fundamental rules for DMAIC implementation in six sigma projects are also introduced.

An Evaluation System of Personal Information Competency was developed to evaluate individual Information competency and maturity levels in the enterprises of the information environment. The Evaluation System measures the requirements of information knowledge, skills, and mindset with the evaluation indices of personal information maturity. The indices are customized to four types of business departments - strategy Planning, development/maintenance, business applications, and administration support. Also, a maturity model of personal information competency is defined for interpretation of the evaluation results. The system was applied to assessment of actual human resources, 124 workers in an enterprise, to testify to its practical value. The case evaluation procedures include a series of questionnaires, written tests and application tests.

Genetic algorithms(GA) are based on the principles of natural genetics and natural selection. The algorithm searches an optimum design point using information based on the fitness function evaluated for the population of many design points. An application of GA on optimal design of a truss structure is studied. The terminology and the operating procedures common in GA are formalized by establishing similarities between GA and genetics from biology. In using GA, (1) coding of the design variables, (2) formulation of the fitness function, (3) setting of the termination condition, and (4) establishment of the probabilities are essential. These four points are discussed in the paper.

We develop Mueller-matrix spectroscopic ellipsometry based on dual compensator configuration. This technique is very powerful for measuring surface anisotropy in nano-scale, especially when materials show depolarization. Dual-rotating compensator configuration is adopted with the rotational ratio of 5:3 originally developed by Collins et al[1]. The instrument can provide 250-point spectra over the wavelength range from 230 nm to 820 nm in one irradiance waveform with minimum acquisition time of Tc=10 s. In this work, the results obtained in transmission modes are presented for the initial attempt. We present calibration procedures to diagnose the system from the utilized data collected in transmission mode without sample. We expect that the instrument will have important applications in thin films and surfaces that have anisotropy and inhomogeneity.

An ichthyofauna analysis of the East Sea using quantitative investigation procedures for latitudinal variations of the species richness and clustering of the species list is presented to illustrate the application of the adopted geographical scaling (less than 1:10,000,000) which provides a principal opportunity for common benthic and pelagic biogeographical zonation. The distribution of both pelagic and benthic marine fish biota at a scale of biosphere (or its major sections) was highly influenced by spatial nonuniformity of hydrological structure associated with the various water circulations and frontal zones. Following zoogeographical zonations were established for the East Sea: Osaka, East Korea, Primorye, North Primorye, Northern East Sea, Uetsu, Tsugaru, Soya and West Sakhalin.

CAE technology is an integrated tool including all aspects such as powder, binder system, mixing, injection molding, debinding and sintering. Therefore, CAE technology is considered as one of core technologies for PIM industry in the future. Recently many researchers are developing not only CAE software itself but also application procedures of CAE software. In this study, the applications for CAE technology in PIM industry are presented including feedstock mixing effect, several cases of troubleshooting and optimization procedure.

Rail crossings are major accident-prone areas. Higher traffic volume, frequent rail operation, increased train speed all contribute to increased accident rate and severity In Korea efforts are being made to upgrade currently at-grade rail crossings to grade crossings. There is, however, no quantified analysis measures to analyse the impact of rail grade crossing, thus make it difficult to prioritize different projects under the budget constraints. Projects are selected based on the negotiation between Korea National Railway(KNR) and local governments. To shed light on the development effort for Korean procedure, GradeDec 2000 program of Federal Railroad Adminstration(FRA) was applied for Korean context. Case study involving three rail crossing was ca]lied out, and results are analyzed. Research efforts which need further attention are identified, research direction is analyzed considering local procedure, and issues in the application of the procedures are discussed in detail.

When a real-time image processing application is implemented with a general-purpose computer, CPU (Central Processing Unit) is usually heavily loaded and in many cases that CPU alone cannot meet the real-time requirement at all. Most modern computers are equipped with powerful Graphics Processing Units (GPUs) to accelerate graphics operations. There is a trend that the power of GPU outgrows that of CPU. If we take advantage of the powerful GPU for more general operations other than pure graphics operations, the processing time can be reduced. In this study, we will present techniques that apply GPU to general operations such as image processing procedures. Our experiment results show that significant speed-up can be achieved by using GPU.
