Natural product drugs, or botanical drugs, are drugs composed of natural substances which have constituents with healthenhancing or medicinal activities. In Korea, government-led projects brought attention to botanical drugs invigorating domestic botanical drug industry. Foreign markets, as well, are growing bigger as the significance of botanical drugs stood out. To follow along with the tendency, Korea puts a lot of effort on developing botanical drugs suitable for global market. However, standards for approving drug sales vary by countries. And also, thorough standardization, certification, clinical studies and data of these will be required as well as data confirming safety and effectiveness. Meanwhile, as an international exchange in botanical drug market continues, the importance of plant resources was emphasized. Thus countries' ownership of domestic natural resources became vital. Not only establishing a systematic method to secure domestic plant resources, but also cooperation with other countries on sharing natural resources is essential to procure natural resources effectively. Korea started to show visible results with botanical drugs, and asthma/COPD treatment made out of speedwell is one example. Sufficient investment and government's active support for basic infrastructure for global botanical drugs will bring Korea to much higher level of botanical drug development.

Purpose - In this study, we try to measure the efficiency of the traditional market and university cooperation projects and present the direction of policy improvement for the near future by converging the system, which exerts to secure the competitiveness and revitalize its centered-city, and the recent policies that have new business and social Research Design, Data, and Methodology - In order to improve this situation, this study uses Data Envelopment Analysis (DEA) to evaluate the effectiveness of the policy project and propose its evaluation results. Also, we want to derive the weight calculation for utilizing DEA by using AHP method. Results - This study's results were derived from the input and output variables, so instead of qualitative analysis, the conclusion was drawn out from the quantitative analysis. Through this quantitative analysis method, we had an opportunity to identify the characteristics of each site by each year. Conclusions - It is believed that the reliability of the results can be further improved if the qualitative part can be supplemented its unique characteristics of the model which only considers the simple quantitative aspect. Further studies should be undertaken as these sectors are expected to draw out fruitful research conclusion when these aspects were supplemented additionally, so continuous additional study is essential.

Purpose: This study analyzed the policies on and changes of elite training through overseas study and their impact on China's national development when entrepreneurs return home. In particular, it analyzed returnee entrepreneurs in the distribution industry. Research design, data and methodology: This study largely analyzed the Chinese government's policy of attracting foreign talent and the results of the policy. The research method utilized the Chinese Statistical Yearbook and various literature. This study also used case analysis methods for start-ups by haigui in the distribution industry. Results: According to the analysis, the Chinese government is implementing various policies to attract talent. Representatively, the government actively attracts talent through the Hundred Talents Plan, Thousand Talents Plan, Chunhui Program and Chizi Program. In addition, the Changjiang Scholars Program is attracting foreign talent. As a result, many talented people are leading development of the Chinese economy. Conclusions: The Chinese government is actively pursuing policies to attract talents from overseas. In addition, it has established a system in which government ministries and research institutes can work closely together to secure effectiveness in attracting overseas talents. Through this, overseas talents are playing an important role in China's economic development through new start-up activities including the distribution industry.

There is Increasing world-wide interest in diesel particulate filters (DPF) because of their proven effectiveness in reducing exhaust smoke and particulate emissions. Fine particulates have been linked to human health . DPF use requires a means to secure the bum-out of the accumulated soot, a process called regeneration. If this is not achieved, the engine cannot continue to operate. A number of techniques are available, but most are complex, expensive or have a high electrical demand. The use of fuel additives to catalyse soot bum-out potentially solves the problem of securing regeneration reliably and at low cost. Work on organo-metallic fuel additives has shown that certain metals combine to glove exceptional regeneration performance. Best performance was achieved with a combination of iron and strontium based compounds. Tests were carried out un a bed engine and on road vehicles, which demonstrated effective and reliable regeneration from a tow dose fuel additive, using a single passive DPF. No control valves, flow diverters. heaters or other devices were employed to assist regeneration. Independent particle size measurements showed that there were no harmful side effects from the use of the iron-strontium fuel additive.

Ad hoc networks play an important role in mobile communications, and the performance of nodes has a significant impact on the choice of communication links. To ensure efficient and secure data forwarding and delivery, an intelligent routing protocol (IAODV) based on learning method is constructed. Five attributes of node energy, rate, credit value, computing power and transmission distance are taken as the basis of segmentation. By learning the selected samples and calculating the information gain of each attribute, the decision tree of routing node is constructed, and the rules of routing node selection are determined. IAODV algorithm realizes the adaptive evaluation and classification of network nodes, so as to determine the optimal transmission path from the source node to the destination node. The simulation results verify the feasibility, effectiveness and security of IAODV.

It is essential to build a high quality database in developing a UIS to enhance the administrative effectiveness of municipal governments. To secure such a high quality DB, a proper methodology of quality control should be established. It is imperative to have such a method fit UIS DB considering that the conventional method has mainly been focusing on the quality control of the digital layers itself. Therefore, this study have analyzed the city of Inchon's UIS DB to devise a proper method to categorize the types of errors and to identify major relevant items. Also, the magnitude and frequency of each error along with its major cause have been analyzed to propose a quality control procedure to minimize the errors

In apartment buildings, casualties, especially fatalities have occurred in balcony areas in fires if residents fail to escape to the main entrance. Potential consequences of a particular infrequent event should be considered. In attempting to design apartment buildings for fire safety, alternative escape methods such as vertical penetration could be considered. The purpose of this study is to investigate present building regulations regarding apartment buildings and examine pros and cons of the current escape method and alternative escape methods. Focus group interview was conducted to discuss problems of fire escape methods. In addition, questionnaires were distributed to field professionals working in architecture, construction and related industries. Among 500 questionnaires distributed, 192 questionnaires were collected. Usable 162 questionnaires were analyzed using SPSS 15. Regarding alternative fire escape methods, several concerns were mentioned. Safety, privacy, security, effectiveness of escape, water proof problems were raised. Based on the opinions, vertical penetration between apartment unit appeared more safe, secure, effective than horizontal penetration. However, both methods have its own pros and cons under specific contexts. Alternative escape methods need be considered for a selective options for residents in case of fire.
