Certification of product means that the process and result in which the verification of required performance of each product was done. For this, advanced countries have established their product certification system. This paper summarize the status of foreign railway product certification system and give out meaningful considerations. Moreover, problems of domestic railway product certification system will be discussed and requirements for the improvement of the system will be proposed.

International electronic commerce is different with international commerce in the aspect using electronic media and non-face transaction so there are some problems as authentication, integrity and non-reputation. These problems of electronic document and signature are resolved from electronic certification system. To introduce and develop the electronic certification in the international electronic commerce, it needs to authorize and operate certification authority under the uniform regulation base. But, because the laws and guidelines that related to electronic certification system are different among the nations and international organizations, it needs to compare each nation's law or guideline. In conclusion, to resolve problems of certification and develop certification system in the international electronic commerce, we make uniform rule of international electronic certification and harmonize the technology of electronic certification.

Researches and developments of tidal energy converters are close to commercialization stage. But, commercialization of tidal energy converters is not ready in korea. In Europe, many experts of company, laboratory and public institution involved in marine energy are active for commercialization of marine energy converters in European Marine Energy Centre. Furthermore, in IEC/TC114, standardization of technical standards for assessment and certification of tidal energy converters of each country is under discussion. Therefore, We have to prepare for commercialization, standardization and entry into the overseas market. In this study, trends of commercialization and standardization of international markets of marine energy converters are investigated and certification schemes of overseas are analyzed. We expect that this study will make contribution to establish the foundation of commercialization of tidal energy converters.

The MANET has many problems in security despite of its many advantages such as supporting the mobility of nodes, independence of the fixed infrastructure, and quick network establishment. In particular, in establishing security, the traditional certification service has many difficult problems in applying to the MANET because of its safety, expandability, and availability. In this paper, a secure and effective distributed certification service method was proposed using the Secret Sharing scheme and the Threshold Digital Signature scheme in providing certification services in the MANET. In the proposed distributed certification service, certain nodes of relatively high safety among the mobile nodes consisting of the MANET, were set as privileged nodes, from which the process of issuing a certification started. The proposed scheme solved problem that the whole network security would be damaged by the intrusion to one node in the Centralized Architecture and the Hierarchical Architecture. And it decreased the risk of the exposure of the personal keys also in the Fully Distributed Architecture as the number of the nodes containing the partial confidential information of personal keys decreased. By the network simulation, the features and availability of the proposed scheme was evaluated and the relation between the system parameters was analyzed.

The certification of software products can provide a greater level of acceptance and feeling of security to customers of these products. This paper presents a certification method for the quality of package software. First of all, the evaluation criteria are derived from ISO/1EC 9126 and 12119 standards, and then the evaluation module are designed considering the measurement scale type. The results can be applied to construct the certification scheme of software product quality for the commercial purpose.

Tonnage taxation has contributed to developing the Korean maritime industry through tax relief for shipping companies. The current tonnage taxation relies on the net tonnage as an earning-capacity indicator in a merchant ship. Although the tonnage tax accords with horizontal equity, it does not match vertical equity because of the different taxable capacities of an individual company. Nowadays, maritime transport uses a dedicated vessel, and each shipping freight embeds a different value of time. It means the tonnage taxation regime should consider the added value of each shipping freight. Meanwhile, as the environmental regulations led by the International Maritime Organization are being strengthened, the Korean merchant fleet must be eco-friendly soon after. This study explores the alternative to renewing tonnage taxation by utilizing the Greenship certification and considering the ability-to-pay principle. Because the Greenship certification scheme encourages shipping decarbonization, maritime transport by a certified ocean-going vessel comes to be treated as an activity for the green economy. Special taxation for the green economy may contribute to shipping sustainability and market competitiveness.

This paper shows that a scheme provided by An[7] is not enough to satisfy security requirements for a user certification using a password-based smart card. In order to compensate this weakness, this study provides an improved user scheme with a hash function and ElGamal signature. This new scheme has some advantages protecting password guessing attack, masquerade, and replay attack as well as providing forward secrecy. Compared to An's certification scheme, this scheme suggests that the effect of computational complexity is similar but the efficiency of safety is better.

This study was carried out to examine the perceptions of consumers and forest product manufacturers in South Korea about forest certification and to identify their willingness-to-pay for certified products by personal interviews. Sixteen percent of interviewees knew and heard about forest certification. However, fifty-six percent of interviewees had an intention to participate in forest certification system. The consumers' group can be described in relative terms as the male of 30 age bracket. The average price premium charged to consumers was higher than one paid to manufacturers, and thus manufacturers are willing to include the additional costs for certified products.
