This paper disscusses about the e-commerce and the various types of e-commerce disputes. Through empirical examination on the dispute consiliation system and by comparative analysis it is derived out of the weakness of current system and finally some suggestions for improvement. First, it is recommended that the more sophisticated knowledge concerning e-commerce should be proliferated through the existing institutions. For example, disputes for B2C could be managed by the consiliation system of consumer dispute consiliation in Consumer Protecion Board of Korea, while B2B by the arbitration system of the Korean Commercial Arbitraion Board. Second, the role of Korea Institute for Electronic Commerce established for the purpose of consiliation of e-commerce disputes is much emphasized. For successful achievement, it is necessarily required to reinforce the related laws, systems, institutions and human resources. Finally, it is also suggested that the the Korean Commercial Arbitraion Board and Consummer Protection Board of Korea fully cover consiliation and arbitration, while Korea Institute for Electronic Commerce activates its proper role of consulting and ad hoc arbitration by using electronic information. The paper points out the last one as the most desired practice.

Acute injuries to skeletal muscles can lead to significant pain and disability. Muscle pain results in muscle weakness and range of motion (ROM) decreases. Pulsed electromagnetic fields (PEMF) promote tissue repair, healing rates and reduce musculoskeletal pain. The results of many previous studies suggest that PEMF can contribute to chronic pain reduction, particularly in musculoskeletal injurys. However, we do not have enough information of its effects compared to a placebo. The principal objective of this study was to investigate differences in acute pain induced by the direct destruction of muscle tissue (extensor digitorum) with varying times of the application of PEMF, measured through the expression of c-fos on the spinal cord. Significant reduction of pain was found in groups exposed to PEMF and the group exposed to PEMF immediately after muscle injury showed the most significant differences. In conclusion, PEMF may be a useful strategy in reducing acute pain in muscle injury.

Purpose: The study was done to identify the perceived health status of elderly women and men, and define the difference between the two groups. Method: The subjects of this study were 209 elderly people over 60 years living in urban areas. The data was collected through personal interviews using questionnaires from September to October 2002. Data was categorized by content analysis and then data was analyzed with the SPSS program by frequency and Chi-square tests. Result: Elderly women complained of types of pain(leg pain, arthritis, lumbago, headache) more than elderly men. Elderly men complained about decreased levels of activities such as walking and general weakness. Elderly men and women have discomforts in daily living such as walking and doing household chores. First, elderly men and women want good health and improvement of health status. Second, women want happiness for their offspring, but men want to improve the government and the laws. Conclusion: Elderly women want relief from pain, but elderly men want an increased level of activity. The findings of this study give useful information to conduct health education and care for elderly women.

In this paper, we propose an efficient two-flow zero-knowledge blind identification protocol on the elliptic curve cryptographic (ECC) system. A. Saxena et al. first proposed a two-flow blind identification protocol in 2005. But it has a weakness of the active-intruder attack and uses the pairing operation that causes slow implementation in smart cards. But our protocol is secure under such attacks because of using the hash function. In particular, it is fast because we don't use the pairing operation and consists of only two message flows. It does not rely on any underlying signature or encryption scheme. Our protocol is secure assuming the hardness of the Discrete-Logarithm Problem in bilinear groups.

BOLERO project and TradeCard System are attracted public attention as new settlement method that is able to substitute for documentary letter of credit. BOLERO is the business processes and methods, together with the digital information system, which are provided by Bolero International for communicating Messages and Documents and facilitating business transactions. TradeCard aim to make international business-to-business e-Commerce easy, fast, inexpensive and secure while innovating current documentary compliance and financial settlement mechanisms. The main purpose of this paper is to search the possibility of paperless trade. Since, this paper examine the international legal feasibility of these systems and compare the strength and weakness.

MQTT is a lightweight messaging protocol that can be used for low power IoT devices. The MQTT basically uses single MQTT broker to indirectly share message information between publishers and subscribers. This approach has a weakness in regard to traffic overflow, connection fault, security, etc. In this paper, we propose a distributed MQTT broker architecture that solves the problems in single MQTT broker structure. The distributed MQTT broker architecture is expected to support new application services that cannot be supported by a conventional MQTT architecture. We have designed and implemented a distributed MQTT broker architecture based on the RPL protocol that has been widely used for IoT network. The experiment results show that the proposed MQTT broker architecture represents better publishing/subscribing latency and network stability than the conventional MQTT broker architecture.

It has been known generally that investment in the extending ability to use the IT applications have further enhanced the productivity of effects of IT on firms by reducing costs, increasing returns, and increasing the speed of operations, etc. Notwithstanding this fact, it was very complex and difficult to evaluate concretely the effect of informatization of firm. SMEs(Small- & Medium-sized Enterprises) in particular. In this study, I point out the weakness of SMEs and analyze the effects of informatization through the count data model. For this analysis, I separate the effects into two part, such as organizational effect and personal effect. It comes to conclusion that organizational effect is larger than personal effect and the ability to practical use of IT systems is most efficient item related with informatization level. Since it will be important to cencentrate on raising this ability for heightening the competitiveness of SMEs.

It is essential to perform the software process improvement activities to reinforce the software quality. Some companies are trying to improve the software process capability by establishing and implementing the software process improvement strategies voluntarily. But, the whole software industry is not active yet in terms of software process improvement. In this paper, we surveyed 'Software Process Capability Level' of software companies, analyzed the strength and weakness of the companies and provided with systematic approaches to improve Software Process capability. So, this paper contributes that software companies vigorously focus on the Software Process Improvement and eventually have the global competitiveness in terms of software quality.

A 3-year-old female Cocker Spaniel dog acutely developed hepatopathy following ingestion of root of Cycad (Cycas revoluta). Seven hours after the ingestion, she showed acute continuous nausea, vomiting, and marked depression and was presented to the local veterinary clinic. At physical evaluation, the dog showed moderate weakness, pale mucous membrane, jaundice, and dehydration. Serum biochemical analysis revealed elevated alanine aminotransferase and aspartate aminotransferase, and mild azotemia. The dog was treated with intravenous fluid, antibiotics, and hepatic protectants for 10 days and recovered without any sequela. Although the ingestion of Cycad in dogs is rare, it can be treated successfully with appropriate supportive therapy.

When multiple objectives exist, there are three approaches exist. These are maximin design, compound design, and constrained design. Still, each of three design criteria has its own strength and weakness. In this paper Hybrid approach is suggested when multiple design objectives exist, which is a combination of maximin and constrained design. Sometimes experimenter has several objectives, but he/she has only one or two primary objectives, others less important. A new approach should be useful under this condition. The genetic algorithm is used for few examples. It has been proven to be a very useful technique for this complex situation. Conclusion follows.
