Introduction : Even though Acupuncture has been know for its effect for a long time, recently it is required to verifiy its effect. To solve this, clinical trial, based on EBM, has been the way to explain acupuncture's treatment effect. Methods: Last year we had a clinical trial based on acupuncture. From this experience we came to a conclusion mentioned below. Results : 1. To find out acupuncture's effect more certainly, it is needed that Korean medical method or treatment should be connected to diagnosis. 2. We had found out that sham and minimal acupuncture are the most appropriate way in single blinding. 3. It is required for the acupuncturist to practice the right real acupuncture point and sham's point in clinical trial. 4. The most important thing to maintain the subjects from dropping out is to always be concerned to the subjects and management them. Conclusion : The best way to advance clinical trial on acupuncture is to use single blinding system with sham acupuncture together in controlled groups and most of all also needs a standardized acupuncture point and depth.

With environmental problems and pollutions accumulated by continuous towns or cities developments events, it is becoming necessary to develop in consideration of environmental effects. This consensus leads to prepare a plan system and instrument for ecological city development, which can be a series of planning indicators. To develope a series of process for environmental friendly development, this study has three main goals as follows; development of policies and programs for environmental friendly development, suggestion of environmental friendly urban design models and standards, development of planning indicators and design guidelines Korean land use plan is operated by both zoning system and detailed plan system. But the available kinds of zoning type are too limited to apply to various and vernacular places. In addition to, the detailed plan is understood to be another regulation which constricts the freedom of building right. In this study, Plan System of Environmentally Friendly Space was studied for domestic affairs In German, Plan System of Environmentally Friendly Space is the field have been progressed before. so In this study, example of German was researched intensively, and Plan System of Environmentally Friendly Space was developed, applicable for the real state in domestic. This study was focused on methodology of landscape planning and planning for afforestation. Landscape planning is performed on condition detail investigation of existent state of nature and local characteristic, and Investigation of Planning for afforestation is more detailed than that of Landscape planning. In the basis of methodology of landscape planning and planning for afforestation, Plan for Environmentally Friendly Urban Habitation Model was developed. Plan for Environmentally Friendly Urban Habitation Model was applicable for state of land use planning. Site was selected Chuk-chun in city yang-in, taking the circumstances into consideration. So landscape planning correspond to land use planning was made out. Adjustment of Land use planning and Landscape planning was very important.

During the sea trial test for the aerovane in AOE-II, a malfunction occurred in the wind detector movement around 40 to 90° on the starboard side and around 270 to 320° on the port side. The purpose of this study was to analyze and improve the cause of the above phenomenon. The wind detector was covered with a mast structure and was not affected directly by the blowing wind, and a vortex air current was formed behind the mast structure, causing the motion malfunction. The above problem was solved by moving and installing the wind detector on the newly installed mast yard. After conducting vibration analysis and reviewing the effects of vibration, the wind detector was installed in the new mast yard and verified by a sea trial test. Since the improvement plan was slightly effective, the position of the wind detector moved away from the mast on the new mast yard and was re-verified through a sea trial test. The movement malfunction of the wind detector did not occur, confirming that it is an appropriate improvement plan.

Purpose: We proposed the method using dose-volume Histogram index to compare prospective plan trials in tomotherapy planning optimization. Materials and Methods: For 3 patients in cranial region, thorax and abdominal region, we acquired computed tomography images with PQ 5000 in each case. Then we delineated target structure and normal organ contour with pinnacle Ver 7.6c, after transferred each data to tomotherapy planning system (hi-art system Ver 2.0), we optimized 3 plan trials in each case that used differ from beam width, pitch, importance. We analyzed 3 plan trials in each region with isodose distribution, dose-volume histogram and dose statistics. Also we verified 3 plan trials with specialized DVH-indexes that is dose homogeneity index in target organ, conformity index around target structure and dose gradient index in non-target structures. Results: We compared with the similarity of results that the one is decide the best plan trial using isodose distribution, dose volume histogram and dose statistics, and the another is using DVH-indexes. They all decided the same plan trial to better result in each case. Conclusion: In some of case, it was appeared a little difference of results that used to DVH-index for comparison of plan trial in tomotherapy by special goal in it. But because DVH-index represented both dose distribution in target structure and high dose risk about normal tissue, it will be reasonable method for comparison of many plan trials before the tomotherapy treatments.

The maritime sector is advancing with dedicated endeavor to reduce greenhouse gas in addressing issues with regards to global warming. Since 01 January 2013, the International Maritime Organization (IMO) regulation mandatory requirement for Energy Efficiency Design Index (EEDI) has been in place and should be satisfied by newly-built ships of more than 400 gross tonnage and the Ship Energy Efficiency Management Plan (SEEMP) for all ships type. Therefore, compliance to this necessitates planning during the design stage whereas verification can be carried-out through an acceptable method during sea trial. The MEPC-approved 2013 guidance, ISO 15016 and ISO 19019 on EEDI serves the purpose for calculation and verification of attained EEDI value. Individual ships EEDI value should be lower than the required value set by these regulations. The key factors for EEDI verification are power and speed assessment and their synchronization. The shaft power can be measured by telemeter system using strain gage during sea trial. However, calibration of shaft power onboard condition is complicated. Hence, it relies only on proficient technology that operates within the permitted ISO allowance. On the other hand, the ship speed can be measured and calibrated by differential ground positioning system (DGPS). An actual test on a newly-built vessel was carried out to assess the correlation of power and speed. The Energy-efficiency Design Index or Operational Indicator Monitoring System (EDiMS) software developed by the Dynamics Laboratory-Mokpo Maritime University (DL-MMU) and Green Marine Equipment RIS Center (GMERC) of Mokpo Maritime University was utilized for this investigation. In addition, the software can continuously monitor air emission and is a useful tool for inventory and ship energy management plan. This paper introduces the synchronization and identification method between shaft power and ship speed for EEDI verification in accordance with the ISO guidance.

Clinical trials are experimental studies with human subjects in which various limitations and variables exist by their nature. As a preparatory stage for designing clinical trials in Oriental medicine, this study considers a virtual protocol to show guideline regarding tasks necessary when writing a trials protocol. Clinical trials have many difficulties in planning, procedure, and interpretation of results, and these may be influenced by various biases that are difficult to predict and eliminate. To deal with these issues, clinical trials need a collaboration between medical experts and biostatisticians from the beginning, through the entire trial, until the final analysis. Therefore, the first stage of clinical trials is to write out a trial plan among the experts in each field to derive the best design for the trial.
