Objectives : To address suitable method for designing clinical trial intervening Traditional Korean Herbal Medicine on General anxiety disorder through the recent clinical research in Chinese Herbal Medicine. Methods : Randomized, controlled trials(RCTs) of treatment of general anxiety disorder intervening herbal medicine were searched through CNKI databases. We examined several item of studies and evaluated using Jadad scale. We searched articles in CNKI with the key word "General anxiety disorder or 廣範性焦慮症", among them we selected the clinical trial studies related with herbal medicine except for case reports, studies of acupuncture therapy or west medicines. Results : 11 RCT studies of herbal medicine met inclusion criteria. The Studies used CCMD-3, HAMA as inclusion tool and mainly HAMA as a evaluation tool. Studies were progressed for 2-8 weeks, mostly used various positive control. Experiment medicine were mainly 理氣劑, 安神劑. In most studies, experiment group made similar or higher efficacy in comparison with control group. Mean Jadad score of studies was $1.3{\pm}0.67$, and only one study was double-blinded among 11 studies. Conclusions : RCT studies on general anxiety disorder of chinese herbal medicine tend to focus on investigating effect of herbal medicine through setting positive control group with CCMD-3 and HAMA. But, most studies had low quality of trial, for lack of pattern identification, evaluation and inclusion tool of chinese medicine. Clinical trials of general anxiety disorder should provide good quality by randomization, double-blinding, and multi-site trial.

High-rise and high-density apartment complexes have been built and supplied on a large scale in the 1st period of the New Town project in metropolitan areas since the late 1980s. Now It has become necessary to improve those apartment complexes, which have serious deterioration problems for aging more than about 20 years accompanying simultaneity and a large scale. The purpose of this research is to develop the evaluating indicators to measure the level of deterioration of apartments inclusively and practically in order to regenerate apartments as sustainable residential environments. This study is composed of the following four parts; (a) establishing the conceptual model of evaluation of apartment deterioration, (b) selecting evaluation items, (c) constituting evaluation measurement, and（ｄ)weighting evaluation indicators. First, deterioration of apartments was conceptualized by physical. social, and economical aspects in terms of sustainable development and proposed the conceptual model of hierarchy structure of evaluation of apartment deterioration by literature reviews. Second, evaluating items were selected based on literature reviews of existing indicators and preceding studies about apartments of Korea and foreign countries. The evaluating indicators were identified as a total of 77 evaluating items which were composed of three dimensions and 9 attributes on the basis of the conceptual model. They cover comprehensive scope of the apartment such as unit, building, complex, and site. Third, as the measurement, the 5 point ordinal scale measure was suggested. The evaluating measurement including measure standards, measure methods, and measure contents were developed by each evaluating items. Lastly, the weighting of evaluating indicators was analyzed by AHP method conducted by survey on the expert group. Items were identified as high contributors or low contributors. The weighting of these items could suggest several evaluations according to the situation. The evaluation of the level of deterioration can be done by both total evaluation and a specific field of evaluation. In addition, it is easy to grasp deteriorated attributes or dimensions by providing a radar and bar chart showing evaluation results. These evaluating indicators could be a useful tool to grasp actual methods for the regeneration of apartments.

The energy storage system consists of batteries, power conditioning system and energy management system. If ESS is installed and operated in the field, SAT(Site Acceptance Test) of ESS is being essentially required for the safety and performance of ESS. Furthermore, in order to more accurately and reliably validate the performance of the ESS in advanced countries, it has been required to perform not only performance testing by H/W equipments but also performance verification by S/W tool. Therefore, this paper proposes the modeling of portable test equipment in order to evaluate the performance and reliability of ESS by using the PSCAD/EMTDC S/W. And also, the prototype of 30[kW] scaled portable test equipments is implemented based on the S/W modeling. From the results of various simulations and testings such as power quality, LVRT and anti-islanding tests, it is confirmed that 30[kW] scaled portable test equipment is useful for SAT of ESS, because the simulation results of PSCAD/EMTDC are identical to them of 30[kW] test equipment at the same test conditions.
