This study aims to investigate and improve the present state of technical standard on building mechanical system in Korea. At this point be tormented the energy depletions are big problem on the rise. Building mechanical system is configured air conditioning, sanitation, urban equipment. In the design of equipment, installation, maintenance, applies to all devices in the field of industrial equipment and general engineering equipment field are within bounds to say that all of the equipment field. However, domestic technology level is still fly short of international standards in architecture, we spent much energy. Because of this, find the current situation and identify the problems look up ways to improve them.

A temporary work are lifting equipment that tower crane or lift, and temporary architectures that office building and storage in construction site. And it is main construction work that built and used temporarily like to a scaffolding, a walk plate, and a formwork. This study is to adjust breakdown structure of temporary work to introduce technical tendency. With a site manager, it is collected a detailed statement and compared. As a result to break down a tendency that temporary equipment, additional function, and direct work of temporary technique, first, existing detail technical indexes that group I, group J, group K, and group L are classified. Second, due to set up and manage to main agents in case of existing detail technical indexes that B1, B2, it is not wrong to classify. But, it is somewhat different, and therefore adjust it to same level. Finally, as a technical tendency that temporary equipment, additional function, and direct work of temporary technique, it is adjusted the others.

While industrial development as many buildings were builted, amount of energy consume in building also increase rapidly. At this point be tormented the energy depletions are big problem on the rise. The development of renewable energy in trying to resolve the fundamental problem that the technical level is still incomplete. Because of this, reduce energy use in buildings to lot of study. Most of the energy involved in building mechanical system for so many research is continue. Among them, be interested in building mechanical system. Building mechanical system is configured Air conditioning, sanitation, urban (environmental) equipment. In the design of equipment, installation, maintenance, applies to all devices in the field of industrial equipment and general engineering equipment field are within bounds to say that all of the equipment field. However, domestic technology level is still fly short of international standards in architecture, we spand many energy. Because of this, find the current situation and identify the problems look up ways to improve them.

The study aimed to identify the impact of the application of technical equipment for infrastructure to achieve the quality of e-learning for students in the faculties at Northern Border University, in Arar city. The study applied the analytical survey study method. To achieve the study purpose, the researcher prepared a study tool which is a questionnaire to measure the impact o of applying technical instrument for the infrastructure to achieve the quality of e-learning for students. The study sample size reached (218) students from both groups from the university faculties in Arar city. The results of the study revealed a tendency in the study sample's responses to the availability of the majority of the questionnaire criteria significantly. This indicates the positive impact of the application of technical equipment on the infrastructure to achieve the application quality of e-learning at Northern Border University, the study recommended the following: The need to pay attention to measuring the quality of electronic courses every two years in addition to the need to adjust the quality standards of e-content provided through e-learning platforms. Also, there is the gradual application of e-learning at the university in addition to spreading the culture of e-learning quality among all groups of the university community. Also, it is necessary to direct them towards benefiting from the advantages of e-learning that observes quality standards.

In Article 311 of the Regulation on Occupational Safety and Health Standards requires the use of Korean Industrial Standards Act in accordance with the Industrial Standardization Act. However, the classification, inspection, maintenance, design, selection, and installation of explosion hazard locations for explosion and explosion prevention and internalization of 'safety' in the performance maintenance phase of electrical machinery and equipment There is no technical and institutional management plan for remodeling and alteration. Analysis of actual conditions and problems related to the installation, use, and maintenance of explosion-proof equipment, comparative analysis of domestic and international technical standards and systems, technical, institutional and administrative systems and systems related to installation, use, and maintenance of explosion-proof equipment, technical personnel and qualifications, etc. It is to propose legislation, system improvement, and technical standard establishment related to the maintenance of explosion-proof facility performance through improvement of the necessity and feasibility study for establishment of the legal status of the management site and management plan. As technical measures, KS standard revision (draft), KOSHA guide (draft) and explosion-proof facility performance maintenance manual were presented. In addition, the institutional management plan proposed the revised rule on occupational safety and health standards, the revised rule on the restriction of employment of hazardous work, and the manpower training program related to the maintenance of explosion-proof facilities and the qualification plan. Enhance safety at the installation, use, and maintenance stage of explosion-proof structured electrical machinery. It is expected to be used to classify explosion hazards, select related equipment, and to update and standardize standards related to installation, use and maintenance.

In this paper, the regulations and technical standards related to qualification of safety grade equipment in nuclear power plants are critically reviewed with the qualification procedure in terms of structures, systems, and equipment in nuclear power plants. These facilities should be designed and constructed to protect from natural conditions or disasters and to perform their safety functions even in case of postulated accidents. Equipment Qualification is to demonstrate that the safety related equipment is designed and constructed to perform their safety functions under normal and accident conditions. It is classified into environmental qualification and seismic qualification.

In the hazardous areas where explosive liquids, vapors and gases exist, electrical apparatus/equipment should have explosion-proof construction. The consuming of liquefied natural gas(LNG) has markedly increased in the industrial field, especially in aspect of some thermoprocessing equipment, boiler, dryer, furnace, annealer, kiln, regenerative thermal oxidizer(RTO) and so on. Because it has many merits, clean fuel, safety, no transportation/storage facility and so on. It is strongly recommend that the classification of hazards has to be decided to prevent and protect explosion which may occur in thermoprocessing equipment. In this paper, the operated thermoprocessing equipments in industrial area investigated and explosion risk assessment about LNG leakage from its facilities was performed through numerical calculation and computer simulation. Finally, we suggest the systemic/technical approach for safety assessments of thermoprocessing equipments consumed LNG fuel which are specially subjected to classification of hazardous area.
