Background: As the demands of pharmacist's role and quality performance have increased, the verification of pharmacist's ability has been required. In this study, we aimed to select appropriate items for assessment of pharmacist's knowledge, attitude and performance. Methods: Based on the pharmacist job analysis, we selected duties and tasks in consideration of applying pharmacy practical examination through brainstorming of internal researchers and group discussion with experts. Survey was conducted to evaluate the tasks according to the criteria detailed below: Realistic, Understandable, Measurable, Behavioral and Achievable (RUMBA). The subjects included professors at colleges of pharmacy and instructors of institutional or community pharmacy settings. Results: Nine duties including 41 tasks were drawn for the survey through primary internal researchers. Of the 90 respondents, 95.6% were professors or preceptors who was engaged in practical training, and 62.2% had more than five years of practical experience. As a result of survey and discussion with expert panel, selected seven duties were selected as followings: 'Patient (customer) reception', 'Drug preparation and distribution', 'Patient care', 'Administration', 'Patient counseling', 'Non-prescription medication counseling', and 'Provision of drug information'. The final 20 tasks from seven duties were chosen to assess skills that a pharmacist should be able to perform. Conclusion: This is the first study to select the items that can be included in pharmacist practical examination in the future, based on the RUMBA criteria. As a next step, it is necessary to study how to implement these items.

Traffic Matrix estimation has always caught attention from researchers for better network management and future planning. With the advent of high traffic loads due to Cloud Computing platforms and Software Defined Networking based tunable routing and traffic management algorithms on the Internet, it is more necessary as ever to be able to predict current and future traffic volumes on the network. For large networks such origin-destination traffic prediction problem takes the form of a large under- constrained and under-determined system of equations with a dynamic measurement matrix. Previously, the researchers had relied on the assumption that the measurement (routing) matrix is stationary due to which the schemes are not suitable for modern software defined networks. In this work, we present our Compressed Sensing with Dynamic Model Estimation (CS-DME) architecture suitable for modern software defined networks. Our main contributions are: (1) we formulate an approach in which measurement matrix in the compressed sensing scheme can be accurately and dynamically estimated through a reformulation of the problem based on traffic demands. (2) We show that the problem formulation using a dynamic measurement matrix based on instantaneous traffic demands may be used instead of a stationary binary routing matrix which is more suitable to modern Software Defined Networks that are constantly evolving in terms of routing by inspection of its Eigen Spectrum using two real world datasets. (3) We also show that linking this compressed measurement matrix dynamically with the measured parameters can lead to acceptable estimation of Origin Destination (OD) Traffic flows with marginally poor results with other state-of-art schemes relying on fixed measurement matrices. (4) Furthermore, using this compressed reformulated problem, a new strategy for selection of vantage points for most efficient traffic matrix estimation is also presented through a secondary compression technique based on subset of link measurements. Experimental evaluation of proposed technique using real world datasets Abilene and GEANT shows that the technique is practical to be used in modern software defined networks. Further, the performance of the scheme is compared with recent state of the art techniques proposed in research literature.

To strengthen the protection of human research subjects and human materials, the Korean Ministry of Health and welfare proposed the amendment bill of Bioethics and Safety Law(2010) to the Congress. It includes so many meaningful clauses. According to the bill, the scope that this act shall apply will be expended to the research involving human subjects and human materials. In the bill, there are the principles of this act; the protection of the life, health, and dignity of the human subjects, the obtaining of the adequate informed consent, the protection of the human subject's information confidentiality and the human subject's privacy, the assessment and minimizing of the risks involved and the guarantee of the safety for the human subjects, the preparation of the special protection program for the vulnerable human subjects, and so on. According to the bill, Institutional Bioethics Review Board(the same as Institutional Review Board) will be responsible for the auditing and monitoring on the research that was approved by IBRB, conducting the education program for the researchers, IBRB members and administrative staffs, preparing of the special protection program for the vulnerable human subjects, and forming the guidelines for the researchers as well as the review of the research protocols. And the State and local governments shall take necessary measures to support the expending of the social infrastructure. In addition to, IBRB will have to be assessed and to be gained the accreditation by the Korean Ministry of Health and welfare. So, if Bioethics and Safety Law is amended, it will contribute enormously to enhance the level of the human research subjects protection. Also, if this Law is amended, IBRB will play a major role for the conduct of the ethically, scientifically, and legally proper research. But now, as a matter of fact, the capability of IBRB members and IBRB office members is not enough to charge of this role because some people and some organizations does not know the importance of IBRB exactly. In spite of, IBRB shall be able to this role to protect the human subjects and to develop the level of the research On the international level. Therefore, the State, local governments and the Organization shall back up the administrative and financial terms of the IRB and IRB Office.

As a method of countermeasure to bed degradation and armoring phenomena of bed material in the downstream area of dam reservoirs, sediment augmentation (replenished sediment) has been carried out in many Japanese rivers. In general, bed of the replenished sediment site is composed of rocks, because the site is located in the downstream area of the dams and sediment supply is very small. Bed deformation process has been researched by many researchers. As a method of countermeasure to bed degradation and armoring phenomena of bed material in the downstream area of dam reservoirs, sediment augmentation (replenished sediment) has been carried out in many Japanese rivers. In general, bed of the replenished sediment site is composed of rocks, because the site is located in the downstream area of the dams and sediment supply is very small. Bed deformation process has been researched by many researchers. However, most of them can treat movable bed only and cannot be applied to the bed deformation process of sediment on rocks. If the friction angle between the sediment and the bed surface is assumed to be the same as the friction angle between the sediment and the sediment, sediment transport rate must be smaller without sediment deposition layer on the rocks. As a result, the reproduced bed geometry is affected very well. In this study, non-equilibrium transport process of non-cohesive sediment on rigid bed is introduced into the horizontal two dimensional bed deformation model and the model is applied to the erosion process of replenished sediment on rock in the Nakagawa, Japan. Here, the Japanese largest scale sediment augmentation has been performed in the Nakagawa. The results show that the amounts of the eroded sediment and the remained sediment reproduced by the developed numerical model are $56300m^3$ and $26800m^3$, respectively. On the other hand, the amounts of the eroded sediment and the remained sediment measured in the field after the floods are $56600m^3$ and $26500m^3$, respectively. The difference between the model and field data is very small. Furthermore, the bed geometry of the replenished sediment after the floods reproduced by the developed model has a good agreement with the measured bed geometry after the floods. These results indicate that the developed model is able to simulate the erosion process of replenished sediment on rocks very well. Furthermore, the erosion speed of the replenished sediment during the decreasing process of the water discharge is faster than that during the increasing process of the water discharge. The replenished sediment is eroded well, when the top of the replenished sediment is covered by the water. In general, water surface level is kept to be high during the decreasing process of the discharge during floods, because water surface level at the downstream end is high. Hence, it is considered that the high water surface level during the decreasing process of the water discharge affects on the fast erosion of the replenished sediment.

SWAT is semi-distributed and continuous-time distributed simulation watershed model, which can simulate point and nonpoint source pollutants as well as hydrology and water quality. It was developed to predict the effects of alternative management decisions on water, sediment, and chemical yields with reasonable accuracy. It is able to predict and manage hydrology, sediments, nutrients, and pesticides with Best Management Practices (BMPs) in a watershed. SWAT model also has potential for use in ungauged basins to predict streamflow and baseflow from saturated source area in watersheds. According to various cultivation practices and climate change, SWAT model is available to analyze relative change in hydrology and water quality. In order to establish optimum management of water quality, both monitering and modeling have been conducted actively using SWAT model. As SWAT model is computer program to simulate a lot of natural phenomena, it has limitation to predict and reflect them with on hundred percent accuracy. Thus, it is possible to analyze the effect of BMPs in the watershed where users want to simulate hydrology and water quality only if model accuracy and applicability are assessed first of all and the result of it is well for the study watershed. For assessment of SWAT applicability, most researchers have used $R^2$ and Nash and Sutcliffe Efficiency (NSE). $R^2$ and NSE are likely to show different results according to a warm up period and sometimes its results are very different. There have been hardly any studies of whether warm up period can affect simulation results in SWAT model. In this study, how warm up period has a effect on SWAT results was analyzed and a appropriate warm up period was suggested. Lots of SWAT results were compared after using measured data of Soyanggang-dam watershed and applying various warm up period (0 ~ 10 year(s)). As a result of this study, when there was no warm up period, $R^2$ and NSE were 0.645, 0.602 respectively, when warm up period was 2 years, $R^2$ and NSE were 0.648, 0.632, and when warm up period was 4 years, $R^2$ and NSE were 0.663, 0.652 separately. Through this study, sensitive analysis of warm up period in SWAT model was conducted, and this study could give a guideline able to simulate hydrology and water quality for more accuracy than before as users change a lot of warm up periods as well as any simulation parameters.
