Cross-border e-commerce has emerged as a crucial force in stabilizing China's foreign trade, driving the transformation and upgrade of China's foreign trade, and contributing to global economic development and stability. As a result, promoting the high-quality development of cross-border e-commerce has become a common challenge within the Chinese industry. However, with the rapid growth of cross-border e-commerce, it faces new phenomena and challenges, such as a mix of quality, fierce competition, and price competition. Brands serve as distinguishing markers for identifying entities, and brand building is a prudent choice for achieving high-quality development in cross-border e-commerce. This article utilizes brand theory, employing a combined qualitative and quantitative approach, with a specific focus on key elements within the operations of cross-border e-commerce enterprises. Through an analysis of the key elements influencing the formation and development of brands within the internal operations of Chinese cross-border e-commerce enterprises, it investigates their internal formation mechanisms and assesses the significance of these critical factors in influencing brand formation. The research process is based on data from overseas consumers, conducting empirical analysis, ultimately providing certain guidance for brand development in cross-border e-commerce enterprises.

A water quality modeling study was performed for Chunggye stream during combined sewer overflow(CSO) period, utilizing the diagnostic system for water management in small watershed, CREEK-1(Cyber River for Environment and Economy in Korea). This system integrated geogaphic information system, data base, landscape ecological model(FRAGSTATS), watershed model(SWMM), water quality model (WASP5), and computer graphic. In this study, the watershed model and water quality model were extensively utilized so as to simulate water qualities and flow in Chunggye stream during wet periods. The Chunggye stream watershed was divided into 18 sub-basins in the watershed model and the stream reach into 11 segments in the water quality model. The watershed model was validated against field measurements of BOD, TN, TP, and flow at the downstream location, where the model results showed a reasonable agreement with the field measurements at all parameters. From this study, it was shown that the stream water quality would change along with elapsed time from rainfall start as well as rainfall intensity. The model results indicated that the water quality would significantly upgrade due to the first flush and high sewage ratio of CSO at the beginning of rainfall event, but become degraded along with the runoff increase due to dilution effect.

Purpose: This study conducted a survey on the elderly with physical debilities, who are in a medically vulnerable social class, to examine closely their demo-sociological characteristics, unmet needs, dental states, and living qualities and satisfaction levels relating to oral health and social supports to them, and also to prepare the basis for effective public medical policies and health improvement programs aimed at improving the quality of life for the elderly with physical debilities. Methods: Twenty-two elderly care facilities within Jeju Special Self-Government Province participated in the survey. Between 11 January and 5 March 2010, a total of 250 elderly persons(65 and over) with physical debilities were interviewed and their dental health was checked. Results: The results of the survey are as follows. The need for social support for dental care of the elderly with physical debilities was high in the medical institution-supported service (49.6%). The unmet needs for physical care were high in bathing (49.6%) and using public transportation (71.6%). More than half of these surveyed had ten or fewer teeth. The survey found that 31.6% of the participants experienced problems eating, due to poor dental health. Concerning quality of life, 30.5% of those surveyed experienced physical pain. Conclusion: In summary, the ages of the survey participants directly relates to the degree of behavioral debility experienced. The more debility a participant exhibits, the greater is the need for social support and dental care. The dental health of a participant directly relates to a higher quality of life. Good dental health of a participant translate to better quality of life. In light of the fact that the elderly with physical debilities suffer from a lack of accessibility to medical care and worse oral health than do other elderly persons, it is essential to increase accessibility to medical institutions that can provide such services as door to door dental care. Current insurance policies, funding for denture insurance, and free denture and denture-upgrade programs desperately need to be expanded. Therefore, to improve effectively the quality of life for the elderly with physical debilities civil dental medical resources should be encouraged to provide inclusive and prevention-focused medical care. In the public domain, door to door dental care services and cooperation with civil dental care resources need to be improved to increase impartial accessibility to dental medical institutions.

Nowadays the flow of international trade is that there seems to appear economic block significantly because most countries contract FTAs, so our market condition is changing to a severe competitive situation. Korea which has 70% of foreign dependence of trade must get involved in regionalism, and also actively promote FTA more than any other countries. FTA on February in 2006, the pharmaceutical industry are anxious. The pharmaceutical industry in Korea has recently come to a crisis that it is hard to expect a growth due to structure of profit and a change for the worse of management. If Korea-U.S. FTA are contracted in this kind of situation, domestic pharmaceutical companies will be at stake. We can anticipate that FTA with the country that has a strong competitive power like U.S. affect negatively on pharmaceutical industry, because the industry doesn't have enough self-competitiveness. Considering this kind of surroundings, we need to present the policy to enhance competitiveness for damage limitation on pharmaceutical industry by Korea-U.S. FTA. Under this background, this research has groped for a direction to strengthen the competitiveness to develop pharmaceutical industry in quality. The competitive enhancement plan is presented which is divided into the government policy part, the R&D part, and the management part. Although Korea-U.S. FTA is analyzed to wither the pharmaceutical industry, it would be thought that it is a good chance to upgrade domestic pharmaceutical industry if we make the best use of it, and also to make in roads into foreign market.

Recently, also in railway vehicles, related products are being designed and manufactured through RAMS activities in order to secure their reliability, availability, maintainability & safety. Subway operators are conducting R&D on various preventive maintenance methods and applying them to the field so as to establish a reliability centered maintenance(RCM) system. In this connection, manufacturers shall carry out R&D based on reliability from the first design stage of development to provide high quality products to subway operators. And operators shall have the products operated properly to their particular operating environment and managed based on the standard maintenance manual. Not only that, but the related field data shall be fed back into the manufacturers to upgrade upcoming products by organic cooperation between manufacturer and operators. However, the mutually beneficial cooperative relationship is not still developed in the domestic railway industry. In terms of methodology for life prediction, this study was intended to analyze field data on relays used for rolling stocks considering operational characteristics in the position of subway operators and predict parts reliability using reliability prediction program from the standpoint of manufacturers as well.

The number of final appeal(the rate of final appeal: 43%) has been on the increase every year over the past ten years in Korea. The number of final appeal cases given to a justice of the Korean Supreme Court amounts to nearly one everyday, which makes it vulnerable to faulty decisions. Reversal rate of final appeal is as low as 10% with most of the cases being dismissed and hence the percentage of people having trust in the judiciary is merely 27%. In this context, the Korean judiciary has announced its plan to set up a final appellate court in the Supreme Court. The establishment of final appellate court, however, is not only against the Constitution but also hardly seen in other nations. It would only overexpand the Supreme Court. Furthermore, the final appellate court would end up deteriorating into the court of fourth instance and impose extra burden on the government as well as on the disputing parties. Therefore, it is necessary to upgrade the quality of the court by increasing the number of judges in the lower court and let them focus on the fact finding process. Facilitating the ADR(Alternative Dispute Resolution) process such as arbitration would help improve the structure of the judiciary. The incompatibility among the four values of the dispute resolution process(equitability, truth, quickness and efficiency) calls for building comprehensive judicial system in which disputes are settled by choosing either jurisprudence or utility.

The uncertainty assessment is important to improve the reliability of emission inventory data. The DARS (Data Attribute Rating System) have recommended as the uncertainty assessment technic of emission inventory by U.S. EPA (Environmental Protection Agency) EIIP (Emission Inventory Improvement Program). The DARS score is based on the perceived quality of the emission factor and activity data. Scores are assigned to four attributes; measurement/method, source specificity, spatial congruity and temporal congruity. The resulting emission factor and activity rate scores are combined to arrive at an overall confidence rating for the inventory. So DARS is believed to be a useful tool and may provide more information about inventories than the usual qualitative grading procedures (e.g. A through E). In this study, the uncertainty assessment for 2009 CAPSS (Clean Air Policy Support System) emission inventory is conducted by DARS. According to the result of this uncertainty assessment, the uncertainty for fugitive dust emission data is higher than other sources, the uncertainty of emission factor for surface coating is the highest value, and the uncertainty of activity data for motor cycle is the highest value. Also it is analysed that the improvement of uncertainty for activity data is as much important as the improvement for emission factor to upgrade the reliability of CAPSS emission inventory.

The purpose of this study is to find what causes make public projects hold off, going beyond the planned deadline and budget. Using System Dynamics(SD) and their derivative Urban Dynamics(UD) models, it intends to analyze major feedback loops based on VENSIM and to simulate them with STELLA software, all of which are interrelated with various causes of project delay. To prevent or ameliorate project delay, first of all it advises to focus on endogenous delaying factors not exogenous ones. These factors either reinforce or balance certain loops in complex causal structure, In the case example on the Cremation Building Project in Cheongju, Residents’ participation demand make negotiation put off and delayed negotiation reinforces administrative-expediency planning in order to observe a time limit, on the other hand, once building consensus, it increase both the level of planning performance and public trust. In the meantime, the real planning process used to neglect residents opinions and manage public grievance only through compensation, he a result of simulation, visible fruit of negotiation in the initial phase seems to be not satisfactory owing to funds and time consumed, but after reaching an mutual agreement among stakeholders, planning performance is effective and strategic than administrative-expediency planning viewed in both financial and time angle. It proposes to devise specific tools schematizing project implementation. In order to upgrade the quality of project management, it recommends for planners to adopt key concepts based on SD/UD diagrams and causal loops, which would contribute to enriching Planning abbots.
