Two marker compounds of Achyranthis Radix, ecdysterone and inokosterone, were analyzed by HPLC on an ODS column ($250{\times}4.6$ mm, 5 ${\mu}m$) with a mobile phase of 15% acetonitrile containing 0.08% formic acid at a flow rate of 1.0 mL/min and a detection wavelength of UV 254 nm. The method was validated by ICH guideline and applied to the monitoring of marker compounds in 93 samples of Achyranthis Radix collected at various areas in Korea and China. The new content criteria of ecdysterone and inokosterone, established using linear regression method were 0.033% and 0.020%, respectively. When the new content criteria were applied to the quality control test of commercial Achyranthis Radix, 95.4% of total samples including 100% of Korean and 92.6% of Chinese samples were passed the test. Application of new content criteria could protect the Korean products and decrease the distribution of Chinese products with lower quality.

The study is a comparative and analytical study which comprises of the analysis of the rules of the buyer's right to withhold performance where the seller delivers defective goods or documents of three legal systems; the CISG, English law and Korean law. The purposes underlying this study are twofold. The first is to clarify the current position as to the right of withholding performance in the event of the seller's tender of defective goods or documents in Korean law, CISG and English law so that it may assist the parties in drafting the buyer's right to withhold performance in their own contract. The second is to compare the rules of one jurisdiction with those of other jurisdictions and to evaluate the rules in light of the practical functions and benefits of the right to withhold performance and the discipline of comparative law the basic question of which is whether a solution from one jurisdiction may facilitate the systematic development and reform of another jurisdiction. It shows that each jurisdiction does not have any provision or case law specifically dealing with the buyer's right to withhold performance where the seller delivers the goods which are defective in terms of quality or quantity. The absence of such provision or case in each jurisdiction has resulted in either disputes or uncertainty. However, the study executed in light of the primary functions and benefits of the right in practice and the discipline of comparative law reveals that, first, the view in English law which is against recognizing the right may not be justified when one considers the practical importance of having the right and the position taken by the CISG as a well developed and modernized law, second, the view in Korean law which argues that the principle of specific goods dogma on which it is based is extended even to substitutable or repairable goods cannot be also justified on the ground of one's ordinary expectation and the position under the CISG and English law which imposes a contractual duty to deliver non-defective goods on the seller insofar as the buyer's payment is deemed to be made in exchange for the seller's delivery of non-defective goods and they are substitutable or repairable. Regarding the right to withhold performance in the event of the seller's tender of defective documents, the study shows that the relatively detailed rules in English law may be utilized as a guideline to fill the gap in the CISG and Korean law in terms of the practicability and appropriateness to govern documentary sales. Furthermore, it is found that the position in English law which confers on the buyer the right to withhold performance for a trivial defect in documents may be unreasonable in terms of one's need to enable justice to be done in individual cases.

Project Monitoring and Control is one of the required activities in project management. This activity provides the information about whether a project is making a progress as it is planned. It is usually performed in weekly meetings or milestone meetings where the project manager checks the project's current status based on project measures such as schedule, cost and work performance. One of the popular method for project monitoring and control is EVM(Earned Value Management). The major characteristic of EVM is that it uses only one measure 'cost' for schedule and work performance so that it enables 2 independent graphs to be illustrated in one integrated graph based on cost. For applying EVM to a project, it is essential to break whole work to work packages and to assign value of cost to each work package at the initial stage of the project. Therefore EVM is well matched with the lifecycle which requires whole plan at the beginning of project. However, in XP(eXtreme Programming), whole customer requirements are difficult to define and to make a complete plan at the beginning and are more detailed in each Iteration. Therefore EVM is not comfortable method for XP. Therefore in this research we suggest 3 layer EVM which can be applied in XP, and develop a process guidelines based on CMMI(Capability Maturity Model Integration) PMC(Project Monitoring and Control) process area.

This paper is to review a literature concerning Bus Transit Route Network Design(BTRNDP), to describe a future study direction for a systematic application for the BTRNDP. Since a bus transit uses a fixed route, schedule, stop, therefore an approach methodology is different from that of auto network design problem. An approach methodology for BTRNDP is classified by 8 categories: manual & guideline, market analysis, system analytic model. heuristic model. hybrid model. experienced-based model. simulation-based model. mathematical optimization model. In most previous BTRNDP, objective function is to minimize user and operator costs, and constraints on the total operator cost, fleet size and service frequency are common to several previous approach. Transit trip assignment mostly use multi-path trip assignment. Since the search for optimal solution from a large search space of BTRNDP made up by all possible solutions, the mixed combinatorial problem are usually NP-hard. Therefore, previous researches for the BTRNDP use a sequential design process, which is composed of several design steps as follows: the generation of a candidate route set, the route analysis and evaluation process, the selection process of a optimal route set Future study will focus on a development of detailed OD trip table based on bus stop, systematic transit route network evaluation model. updated transit trip assignment technique and advanced solution search algorithm for BTRNDP.

Objectives : The purpose of this study is to investigate the practice patterns of traditional Korean medicine (TKM) doctors and the acceptance of payment model in order to develop a new TKM health insurance payment model linked with TKM clinical practice guidelines (CPGs). Methods : Lumbar herniated intervertebral disc (HIVD) and idiopathic facial palsy (IFP) were selected as a test diseases to develop a new TKM payment model. The level of benefit coverage in the National Health Insurance (NHI) was designed. The survey asked 228 TKM doctors about their practice patterns in HIVD and IFP patients and acceptance of new payment model. Results : Mean of medical cost for treatment of HIVD was 441,000 KW, mean of treatment period ranged from 4.9 to 17.5 weeks, and mean of number of treatment ranged from 14.6 to 50.4 HIVD patients. In the case of IFP, mean of medical cost for treatment of IFP was 468,000 KW, mean of treatment period was at least 4.2 and up to 15.9 weeks and mean of number of treatment ranged from 14.2 to 52 IFP patients. Conclusions : Current study suggests that mixed payment model of per-visit and episode-based model seem to be proper. The model 1 bundles both items which were covered and not covered by NHI in a rational way. The model 2 is based on the development and application of critical pathway. Lastly, model 3 suggests bundling of items covered by current NHI. Acceptance of TKM doctors is expected to be highest in the model 3.

An analytical method for the determination of dexamethasone (DM) in bovine milk samples was developed and validated using liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS). Milk samples were extracted by the liquid-liquid extraction based on acetonitrile. The chromatographic separation was achieved on a reverse phase $C_{18}$ column with gradient elution using a mobile phase of 0.1% formic acid in 95% acetonitrile. The procedure was validated according to the Ministry of Food and Drug Safety guideline determining accuracy, precision, limit of detection (LOD), and limit of quantification (LOQ). Mean recoveries of DM from spiked milk samples (25, 125, and 1,250 ng/mL) were 98.9-109.6%, and the relative standard deviation was between 1.7 and 4.4%. Linearity in concentration range of 12.5-1,250 ng/mL was obtained with the correlation coefficient ($r^2$) of 0.9997. LOD and LOQ for the investigated DM were 0.15 and 0.5 ng/mL depending on milk samples, respectively. This method was reliable, sensitive, economical and suitable for routine monitoring of DM residues in bovine milk.

Recently, more focus is shift to imbalances in aggregate market supply and demand and an exhaustion of natural resources. In this situation, Electric arc furnace oxidizing slag (EAF Slag) has high application possibility as aggregate for concrete due to similar property with general aggregate. In this study, We've got the plan to assure the chemical stability of EAF Slag, and then experimentally tested the mechanical performance and durability for the fine aggregate used EAF Slag. On this test result, we suggest the application plan. At the result of this study, it shows that EAF slag would reduce the surface defect such as pop-out due to natural aging for the fixed hour and adjustment the grain size of EAF Slag. And mechanical performance and durability according to the replacement rate of concrete service, were revealed more than equal or equal compare to general aggregate. Hereafter, quality control must precede not to impede the beauty of concrete surface as assure the safety for aging and processing. And, to establish the environmental resource recycling system for by-products of steel, it should be made development of various application and guideline of quality control for the EAF slag aggregate. Moreover, it must be constantly studied all kind of engineering performance and durability for related to this study.
