  • International trade conflict has been increased since WTO has appeared. Like this, the cause that the number of international trade conflict has been increased is by means of enlargement of agreements range. But some new facts have been added. They are Anti-dumping, subsidy, Countervailing duty, Safeguard, the norm of intellectual property right, the procedure of permitting importing products, Technical Barriers, agricultural products, and the area of textile. Since Japanese government has decided to give lavor import quarters to China without permission of Korea, Korean government formally presented the system of lavor import quarter to WTO DSB due to WTO agreement disobedience of Japan. Accordingly, this paper has the following purpose; to analyze situation on fiber dispute of Japan. Some methods about trade barrier against Japan need to be solved from another viewpoint owing to lavor IQ dispute.

  • Abnomal grain growth behavior of BaTiO3 ceramics was investigated with addition of seed grains. It was foudn that the nucleation rate of abnormal grain was constant and growth of abnormal grain was linearly increased with sitnering time, regardless of amount of seed grains. These facts were also confirmed by fitting of the volume fraction of abnormal grain vs. sintering time using Avrami type equation (n=4). It was suggested that seed grains did not change the nucleation rate or growth mechanism of abnormal grain but increase the number of abnormal grains at initial stage of sintering and then it led to fine microstructure of BaTiO3 ceramics.

  • This paper proposes a 36-pulse back-to-back voltage source converter using four sets of 12-pulse bridges with pulse-Interleaving auxiliary circuit. The proposed back-to-back voltage source converter has an independent control capability of active power and reactive power at the at connection point. The principle of increasing the number of pulses was analyzed using theoretical approach. The operational feasibility of proposed system was verified through computer simulations with PSCAD/EMTDC software. The proposed back-to-back converter can be widely used for the HVDC and FACTS devices.

  • Recent trend of rapid growth in the basic research activities in East-Asian newly industrialized countries bring about the change in the world knowledge production structure. Particularly, Korea showed the changing patterns not only in the number of publication, but also in the aspect of structural change of basic research activities. The stylized facts of basic research activities in Korea can be summarized in three aspects; first, selective development patterns, second, reverse pattern of evolution, and finally, the rapid growth of basic research activities in major firms. This paper analyse the evolutionary patterns of basic research activities in empirical base and propose the policy implication for supporting basic research activity in newly industrializing countries.

  • Currently, inappropriate information regarding cancer is being disseminated indiscreetly via the media and Internet. Many people are confused due to the mixed presence of facts and misinformation concerning cancer. Owing to the flood of information, especially that concerning gastrointestinal cancer (the most common cancer in Korea), patients with gastrointestinal cancers, their family members, and medical staff, as well as the general public, are faced with a number of problems in understanding, treating, and overcoming this type of cancer. Therefore, investigating the level of recognition for and understanding of gastrointestinal cancers among these populations is very important for the prevention, diagnosis, and management of this disease. This review article investigated the differences in the recognition levels of the general understanding, prevention, quality of life, pain control, and the ethical issues of gastrointestinal cancer treatment among the general public, patients with gastrointestinal cancers, their family members, and medical staff via surveys.

  • In the elementary school mathematics textbook that has been revised in 2013, the instructional sequence for teaching addition and subtraction, which had remained unchanged for three decades since 1982, was finally changed in 2013. Particularly, the addition and subtraction of two-digit numbers without regrouping, such as 72+25=97 or 85-24=61, are taught earlier than the composing and decomposing of the number 10 using other numbers. This study examines the appropriacy and validity of these changes. However, the reason for these changes in the national curriculum or teacher's guide could not be determined. Further, several references emphasize the addition of two single-digit numbers, such as 7+8=15, and the subtraction of a single-digit number from a number between 11 and 19, such as 16-9=7, as basic facts. In other countries' textbooks, the teaching of addition and subtraction up to the number 20 is prioritized before teaching the addition and subtraction of two-digit numbers without regrouping. The results of this study indicate that these changes in the instructional sequence in the textbook that was revised in 2013 need to be reconsidered.

  • This study selected Korea and China-related subject headings among all names contained in Japan 2008 Version of NDLSH, and compared and analyzed the number of headings and the features according to each theme. As the result of analysis, the total number of Korea-related subject headings is 222 including its headings and referent words. At comparing with China-related subject headings, the number of Korea-related subject headings was very small size, and shows many limits in terms of the variety or the specificity of themes. Especially, the facts that 'Joseon', which is not existed any longer, is used as Korea's nation name, or that Balhae's history is assigned into Chinese history are required to be corrected quickly. Meanwhile, in the China-related subject headings field, multi-racial nation's features are reflected. and are contained many theme names like ancient racial names, each minority's residental area name and its native language which are rarely appeared in Korean theme names field.

  • Frequent occurrence of binding update messages may incur high overhead in Mobile IP supporting users mobility. Thus, it needs to develop algorithms to deal with the situation. In this paper, we propose new lifetime assignment schemes for dynamic binding update considering the locality property related with mobile node's movement. Each mobile node maintains a profile which is based on log containing useful information about its visiting subnets. That is, it determines dynamic binding update lifetime for currently visiting subnet by computing past mean resident time recorded in the profile. In addition, we note that the resident time depends on the time when each node enters a subnet and thus, we devise another lifetime assignment algorithm. Extensive experiments are made to compare our schemes with existing Mobile IPv6 where major facts for performance comparison are both the number of binding update messages and the number of binding request messages. From the results, we come to know that our schemes obtain highly considerable performance improvements in terms of communication cost by decreasing the number of those messages.

  • Utilizing the patent application data between 1997 and 2002, this study focuses on analysing the impact of patents on firm value. Especially we attempt to examine the difference of patents between venture firms and general firms. This paper first shows that the number of the patent applications of general firms listed on the securities market are more than those of venture firms listed on KOSDAQ. It is thought that this result is originated from facts that the size of firms of the securities market is usually bigger than the firms of KOSDAQ and that these large firms could manage R&D more efficiently. Second, this paper reports that there is no difference in the ratio of patent maintenance between venture firms and general firms. Both venture firms and non-venture firms would do their best to keep their patents after patent regisration. Third, in the regression of patent index and firm growth, we find that the excellence of patent and the number of patents per employee would have an impact on the growth of firms. Fourth, the regression of patent index and profitability shows that the excellence and the number of patents per employee might have an effect on the profitability of firms.

  • In order to observe the kinetic of ciliates inhabited in the stomach, investigation of the content juice in the stomach was carried out on the 30 Korean native cattle, selected as healthy ones and slaughtered at Jeonju abattoir in August, 1974. The following is a brief summary of the leading facts gained through the experiment. 1. The average pH of the content juice showed $6.567{\pm}0.056$(SE) in the rumen, $6.607{\pm}0.053$ in the reticulum, $6.183{\pm}0.056$ in the omasum and $2.627{\pm}0.061$ in the abomasum. 2. The presumed number of ciliates per ml was calculated $168,200{\pm}17,035$(SE) in the rumen, $173,200{\pm}19,728$ in the reticulum, $23.600{\pm}3.537$ in the omasum and $467{\pm}266$ in the abomasum. 3. In the content juice the number of ciliates was gradually slowed down, the pH decreased from rumen to abomasum and the changes were denoted by quadratic curves(parabolas). 4. In accordance with the increase of the number of ciliates the pall also becomes higher and in this situation the correlation coefficient was ${\gamma}_{xy}=0.508$. 5. Population density of ciliates was checked and Entodinium showed 60 per cent among them, but Polyplastron was figured only from 0 to 0.05 per cent. 6. Among 26 species of ciliates which were identified from the content juice, Entodinium simplex was showed the highest population density, raging from 40 to 50 per cent, Dasytricha ruminantium was neat to it, Eudiplodinium affine after the next, and Entodinium caudatum and Eudiplodinium maggi were also found abundantly in the abomasum.
