This Study was conducted to investigate Muscle Test of Point Selection through CRA(Contact Reflex Analysis) Muscel Diagnosis. So this study used to compare and analyze the effects of Muscel(Deltoid Muscel of Posterior) RMS(Root Mean Squared) and MEF(Median Edge Frequency) Among Groups that do not respond to questionnaire, Tonguibogam Naegyeongpyeon Small Intestine Group, Small Intestine MeridianPathway Primary Symptom and Secondary Symptom Group and Kwanwon(CV4) meridian Principal action Group. The questionnaire is composed of 23 items. The questionnaire was intended to elicit information on assorting into 4 groups. After Survey, Subject had to Muscle test subjects. Muscle experimental methods are as follows: Holding the shoulder without contacting Kwanwon. Holding the shoulder contacting Kwanwon. The first iteration. Group 1,2,3 were increased sEMG RMS compared with First experiment and Second experiment. Group 4(Including Uterus and Intestinal Flora Problem) were decreased sEMG RMS compared with First experiment and Second experiment. This test means that it is similar to diagnosis CRA and Small intestine channel of hand taiyang muscle, not Small Intestine MeridianPathway. It is suggested that subjects with a Small Intestine problem(Uterus and Intestinal Flora Problem) shows the results of decreasing posterior Deltoid Muscular strength. It means that CRA muscle diagnosis is associated with Alarm points diagnosis. But it doesn't consider influence of fat on the surface EMG.

어업무선국에서는 연안조업을 목적으로 약 10톤 미만의 소형어선과의 통신망으로 27MHz대의 주파수를 사용하는 SSB통신에 의존해 왔었다. 소형선박의 척수가 늘어나고, 어업통신본부에서는 각 도서지방을 무인화 시킴으로서 소형선박의 입ㆍ출항 및 조업사항을 관장해야 하는 통제 기능이 약화되기 시작했고, 현용 통신방식의 문제점이 드러나기 시작하면서 새로운 통신방식의 도입이 필요하게 되었다. 이들 선박은 SSB보다는 셀룰라폰을 그들의 주 통신망으로 사용하고 있으며 입ㆍ출항 신고는 물론이고 위치보고도 제대로 하지 않고 있는 실정이다. 또한 소형어선들은 항만 내외에서 운항거리를 단축하기 위해 주항로를 횡단하는 등 선박사고가 빈번히 발생하므로, 이런 소형선박의 사고를 미연에 방지하고, 해난사고 발생시 신속한 조치를 취하기 위하여 어업무선국과 선박간의 지속적인 통신을 유지하는 것이 가장 좋은 방법이라는 것은 두말할 나위가 없을 것이다. 현재, 어업무선국과 소형어선간에 사용하고 있는 27MHz의 SSB(Single Side Band)통신방식으로는 통제가 불가능 할 뿐더러 적절한 시기에 적절한 정보를 제공할 수 없는 게 어업통신의 현실이다. 본 연구에서는 10톤 미만의 소형어선과 어업무선국간의 원활한 통신체제를 구축하여 어민의 생명과 재산을 보호함은 물론 긴급상황 발생시 효과적으로 대처하여 소형어선의 해난사고를 줄이기 위한 통신 체제로서 주파수공용방식(TRS: Trunk Radio System)의 도입을 제안하고 그 활용성을 입증하고자 한다.

The purpose of this paper is to propose directions for urban greening and nature conservation in small-to-medium-sized cities in Korea for implementation of the Local Agenda 21 (LA 21 hereafter). In this paper, the status of implementation of the LA 21 in both Korea and Japan have been examined. In addition, the green-related plans of both countries have been compared. The cities of Jeonju and Sagamihara were chosen as examples to compare. The result of the research is as follows: 1)With regard to the responsible bodies, in Korea, the implementing plans were initiated by the environment-related authorities of local governments while, in Japan, the plans of action were initiated through consultative committees reflecting opinions from citizens and business entities. 2)Concerning the status of implementation of LA 21, the city of Jeonju has adopted a plan of action and then implemented the plan through a consultative body without adequate legal ground. On the other hand, the city of Sagamihara has enacted a local ordinance to implement the LA 21 It was learned that the newly enacted ordinance has positively been interrelated to existing environmental plans. 3)Regarding urban greening and nature conservation plans, the city of Jeonju has focused on comprehensive measures to preserve and restore ecology while the city of Sagamihara has clearly suggested educational purposes in its plans in addition to preserving and restoring ecology. 4)In terms of support by law or legal system concerned, it has been teamed that, compared with Japan, Korean plans have not been properly supported by law or the legal system to urban greening and nature conservation plans. The same was shown in the city of Jeonju as compared with the city of Sagamihara. As for future directions, the follow are proposed: 1) establishment of a local Committee on Sustainable Development, 2) enactment of relevant and regulations such as the Master Plan of Parks and Green Open paces, 3) establishment of ecological greening plans.

The CANDU 6 reactor assembly consists of an array of 380 pressure tubes, which are installed horizontally in a large cylindrical vessel, the Calandria, containing the low pressure heavy water moderator. The pressure tube is located inside the calandria tube and the annulus between these tubes, which forms a closed loop with $CO_2$ gas recirculating, is called the Annulus Gas System(AGS). It is designed to give an alarm to the operator even for a small pressure tube leak by a very sensitive dew point meter so that he can take a preventive action for the pressure tube rupture incident. To judge whether the operator action time is enough or not in the design of Wolsong 2,3 & 4, the Leak Before Break(LBB) assessment is required for the analysis of the pressure tube failure accident. In order to provide the required data for the LBB assessment of Wolsong Units 2, 3, 4, a series of leak detection capability tests was performed by injecting controlled rates of heavy water vapour. The data of increased dew point and rates of rise were measured to determine the alarm set point for the dew point rate of rise of Wolsong Unit 2. It was found that the response of the dew point depends on the moisture injection rate, $CO_2$ gas flow rate and the leak location. The test showed that CANDU 6 AGS can detect the very small leaks less than few g/hr and dew point rate of rise alarm can be the most reliable alarm signal to warn the operator. Considering the present results, the first response time of dew point to the AGS $CO_2$ flow rate is approximated.

우리나라 IT중소기업은 대부분 핵심적인 기술을 가진 기업에게 부품을 수급받고, 이를 조립하여 대기업에 납품하는 기업이 많다. IT 중소기업의 현실적인 지적재산관련 문제는 직접적인 소송 혹은 클레임의 문제가 아니라 계약상의 제 3자 지적재산 침해문제 혹은 계약이 없을 경우에는 각 준거법상의 묵시적 손해배상 책임의 문제이나, IT중소기업의 협상력이 크지 않기 때문에 계약상에 명시적인 보증조항을 삽입할 수 없고, 각 준거법상으로도 소송의 경제성이 없는 경우가 많아서 실효성이 없기 때문에 이에 대해서 정부기관 및 산하 연구기관에서 연구을 하여 개선안을 도출해야한다고 생각된다.

The sea water and the soil of surface zone in lagoon have many physical relations between each other by both physical phenomena such as tidal motion and wave action, and activity of a creature which lives in soil zone. The soil zone has an activity of filtering the sea water at lowering tide and also the organic materials in sea water are supplied into the soil. And small creatures such as small crab eat organic materials. Usually the surface zone of lagoon becomes under the sea water in two times of a day and also is coming in two times under the sunshine and it becomes dries up conditions. Authors made the field observation at Sanbannse lagoon in Tokyo bay in several times between 2002 to 2004. The observation has been done in a half period of tide in October and November 2002 and also full tide observation is made in July 2, 2003 in summer and November 26, 2003 in autumn. In 2004, three times observations of full tide has been made in three times as June 22, July 20 and December 14. This report is the summary of results on these observations focusing on the soil surface zone and sea water at under ground and wave breaking zone.

A control system for stabilizing a small robot or inverted pendulum using twisted gyro wheel is proposed. Conventional stabilizer using inertial wheel employs action-reaction force/torque to control a pendulum, which can generate relatively small torque and short period of output. In this paper, a novel actuation method using twisted gyro torque in 3-dimentional space was proposed to stabilizing a pendulum by twisting the assembly including a rotating gyro wheel. In addition, two special control functions for this type of twisted gyro wheel were designed. One is the function of self-adjusting the mass center of the robot and the other is the torque reloading configuration for continuous torque generation. The proposed system was verified by experimental result and simulation. The designed twisted gyro wheel control system can be easily packed in a small size module and installed in a humanoid robot or inverted pendulum type mechanism.

A small-scale electro-dialysis system was constructed for domestic use. It is composed of six compartments in which five special polystyrene ionic membranes are housed. A series of experiments on the transport of sodium and chloride ions through polystyrene membranes was performed and the effects of electric current and voltage on the pH of water were investigated. This electrodialyser could reduce the NaCl content to an acceptable level (5307 mg/L) when water containing 9945 mg/L of sodium chloride is fed to the electrodialyser. The reduction was by the action of direct current 60 mA/100 mA when a 15 V / 20 V potential is maintained across the membrane. The results showed that the pH of the treated water attained a value in the range of 7-8, with the chloride concentration of 5307 mg/L when the voltage was in the range of 20 volts. This was achieved when two of the small-scale electro-dialysers were placed in series and the solutions from the respective compartments were mixed. This is considered useful because this complies to the requirement of drinking water standard both in terms of chloride and pH. Therefore, this type electrodialyserhas the potential for domestic uses in isolated houses where potable water supply is not available.
