The collateral diagnosis method is unique in Traditional Chinese Medicine diagnosis methods which has important clinical value. In my article, the contents of the "Hwangjenaegyeong(黃帝內經)" related to this method is discussed. According to the site of inspection in the diagnosis process, there are five types as following: inspection of the face and surface, the thenar, the orifices, abdominal collaterals and finally the index finger of children. This method can inspire clinical practitioners.

In 2008, 17, 596 dams and reservoirs are scattered across South Korea, and 17, 505 of them (99.5 %) are used for agriculture and 99.3 % are fill dam types. This study aimed to review literature related to the precise safety diagnosis system for agricultural reservoirs established by Korea Rural Community Corporation (KRCC) and analyze problems of its evaluation method. And then, it proposed ways to improve the system including a modified diagnosis system, which was applied to pilot districts in order to verify the utility. For assessment model development of agricultural reservoir, we reviewed status of precision safety inspections systems of agricultural reservoir. There are many problems such as assess agricultural reservoir not by sheet which used in fill dam but by block which used in concrete dam construction and diversion tunnel which main element in reservoir levee is treated as water intake facility. For considering diversion tunnel in reservoir levee, previous precision safety inspection systems which summed in separated phenomenon, separated element, separated site, separated facility was change to new systems which summed in site, phenomenon, element, and facility. Compared results of previous inspection system calculated total assessment index (Ec) with new system calculated total assessment index (Ec) are not show statistical difference.

Public institutions have a responsibility to ensure the safety of their employees and the public. One way to do this is to implement a systematic safety inspection system based on risk assessments and continuous improvements. This study developed a systematic safety inspection system for public institutions that are ordered construction projects. The proposed system in this study consists of a three-step process: (1) developing safety grade evaluation tables, (2) preparing and conducting safety inspections, and (3) evaluating and improving safety management grades. The first step is to develop safety grade evaluation tables by analysis and diagnosis of the construction site's work type, disaster statistics, and related laws. The second step is to conduct safety inspections using the developed evaluation tables. The third step is to determine the safety management grade based on the results of the safety inspection, and to improve risk factors found during the safety evaluation. The proposed system was implemented in highway construction projects carried out by public institutions. The results showed that the proposed system has two major effects: (1) reducing accident-related deaths and injuries, (2) improving safety management levels by continuous evaluation and improvement. The proposed system can be utilized in construction projects ordered by public institutions to improve the level of occupational safety and health.

The purpose of this study is to develop Deterioration Diagnosis System for the Reinforced Concrete Structure which can be used preliminary in determining the factors causing deterioration by simple inspection and mapping of the indicators of deterioration. Total 29 items compromising material, structural and constructional factors causing deterioration were considered in this system. Also the indicators of deterioration were subdivided into 54 items such as concrete crack pattern and steel corrosion etc. Each indicator of deterioration was quantatified by allocating and giving grade to each item which has extra weight according to its conscquence. Satisfactory results were obtatined by applying this Diagnosis system to the indicators of deterioration in ref. [3]. Further research was required on the indicators of deterioration in construction site to enhance the field applicability of this system.

This study investigated the detection of corona discharge on polymer insulators at 13.2kV. Also, It will be analyzed by variety analyzers such as FT-IR, TA, and so on. It carried out an experiment and an actual measurement about corona detection using a UV-camera. This experiment and inspection would need to respect the above criteria. It was required to verify various experimental conditions and on-site inspection afterwards, but it was believed to minimize the measurement error by data-basing research results in a continuous manner and it was necessary to establish diagnosis technologies and standards in various electrical power facilities.

Key set the current non-urban rail power failure of equipment to operate the railway will generate a lot of problems. I know in advance the ideal of power equipment to prevent the failure to derive an efficient replacement cycle for the power equipment monitoring and diagnosis of the condition can become necessary to develop a system. In order to determine the status of the power plant during operation and behavior of the partial discharge current state data, regular monitoring and inspection requirements also stamp the basic current, voltage, temperature and humidity should be identified.

Recently, interest in ground subsidence in urban areas has increased after a large sinkhole occurred near the high-story building area in Jamsil, Seoul, Korea, in 2014. If a massive sinkhole occurs in an urban area, it is crucial to assess its risk rapidly. Access to humans for on-site safety diagnosis may be difficult because of the additional risk of collapse in the disaster area. Generally, inspection using drones equipped with high-speed lidar sensors can be utilized. However, if the sinkhole is created vertically to a depth of 100 m, similar to the sinkhole in Guatemala, the drone cannot be applied because of the wireless communication limit and turbulence inside the sinkhole. In this study, a three-dimensional (3D) scanning system was fabricated and operated using a towed cable in a massive vertical sinkhole to a depth of 200 m. A high-speed lidar sensor was used to obtain a continuous cross-sectional shape at a certain depth. An inertial-measuring unit was applied to compensate for the error owing to the rotation and pendulum movement of the measuring unit. A reconstruction algorithm, including the compensation scheme, was developed. In a vertical hole with a depth of 180 m in the mining area, the fabricated system was applied to scan 0-165 m depth. The reconstructed shape was depicted in a 3D graph.

주택법(2014년)에 근거하여 철근콘크리트 공동주택의 리모델링 시 수직 및 세대수 증축이 가능하게 되었다. 수직증축 리모델링 가능 여부는 안전진단 기준 및 매뉴얼을 바탕으로 기울기 및 침하, 내하력, 내구성 평가 부문에 대한 평가를 통하여 판정하도록 되어 있다. 그러나 증축형 리모델링 기준 및 매뉴얼 제정 당시, 국내에서는 수직증축 리모델링 안전진단 사례가 전무하여 평가기준 등에 대한 공학적 근거 제시에 한계가 있었으며, 특히 내구성 평가 기준에 대한 합리화 및 관련 기준과의 부합을 위한 개선이 필요한 것으로 생각된다. 따라서 본 연구에서는 국내외 내구성 관련 기준을 근거로 콘크리트 탄산화, 염분함유량, 균열, 철근부식, 표면노후도의 허용치와 평가기준에 대한 검토·분석을 통하여 수직증축형 리모델링 안전진단 내구성 평가방법의 합리화 방안을 제시하였다.

주택법에 근거하여 철근콘크리트 공동주택의 리모델링 시 최대 3개층의 수직증축 및 기존 세대수의 15%까지 증축이 가능하게 되었다. 수직증축 리모델링 가능 여부는 안전진단 기준 및 매뉴얼을 바탕으로 기울기 및 침하, 내하력, 내구성 평가 부문에 대한 조사를 통하여 평가하고 판정하도록 되어 있다. 그러나 현행 증축형 리모델링 안전진단 기준 및 매뉴얼은 재건축 안전진단 기준과 비교하여 조사대상표본 수를 증대시키는 등 보수적인 것으로 평가되고 있으며, 특히 내구성 평가 부문에 검토 및 개선이 필요한 것으로 생각된다. 따라서 본 연구에서는 수도권 지역 공동주택의 증축형 리모델링 안전진단 조사 사례에 대한 내구성 조사 항목 중 콘크리트 탄산화를 대상으로 통계적인 수법에 의해 표본 수 합리화 방안을 제시하였다.

건축물 유지관리 단계에서의 안전점검 및 정밀안전진단은 1, 2종 시설물에만 국한되어 있으나 중소규모 건축물이 전체 건축물의 99.4%를 차지할 정도로 많다는 점을 고려할 때, 중소규모 건축물의 안전진단은 반드시 필요하다. 이 연구에서는 현행 안전점검 및 정밀안전진단 체계의 문제점을 고찰하고, 중소규모 건축물에 적용할 수 있는 안전진단 모델을 개발하였다. 현행 평가방식을 고찰하고 설문조사를 통해 기존 상태평가 항목을 중소규모 건축물에 적합하게 조정하였다. 안전진단 모델 개발에 퍼지이론이 적용되었으며, 평가를 용이하게 하기 위해 웹기반 프로그램을 개발하였다. 이 연구의 결과를 실무에 적용한다면 1, 2종 이외의 중소규모 건축물도 안전점검 및 정밀안전진단을 효율적으로 수행할 수 있을 것이다.
