170kV GIS(Gas Insulated Switchgear) is widely used in large industrial factory-electrical facilities of private use because has many benefits. But Other equipments's failures are occurred by GIS failures and give rise economic problems to user. Therefore we will examine the actual condition of the 170kV GIS-electrical facilities of private use and are able to confirm the distribution characteristic analysis of disconnecting switchgear. In this paper, we presents the actual condition investigation of the disconnecting switchgear of 170kV GIS-electrical facilities of private use by post - failure pattern, inspection method, test equipments and so forth.

The purpose of this study is to search for a plan to improve the professionalization of private investigation service through the analysis of its actual condition. To examine the actual condition of the professionalization of private investigation service, 4 factors - professional associations, professional knowledge, curriculum & qualification system and code of ethics - were used for the professionalization analysis based on theoretical background and prior researches concerning structural aspect of professionalization. Based on the results of actual condition analysis, to make an effort for the integration and incorporation of private investigation associations, to overcome the unequal distribution of professional knowledges, to organize and operate the professional curriculum, to introduce recognized qualifications system, and to establish a code of ethics are required to improve the professionalization of private investigation service.

In this study the location condition and the management of the Rural Experience Tourism Villages located around unified Cheongju city has been surveyed or investigated. On the basis of the results of the survey or investigation this study is to suggest a way to make activate the Rural Experience Tourism Villages which have been inactive. The ways of the research include the understanding of what means the activation of rural areas and then this study is to find the problems with the Rural Experience Tourism Villages and to suggest final ways or plans after the field investigation of the condition of the location and management of the Villages. In this study I had full understanding of the concept of the activation for rural areas and the humanistic and geographical characteristics and then made a wide investigation and analysis of the location condition and the management of the Rural Experience Tourism Villages in this area. Based on the theory and the results of the actual investigation I made a suggestion of basic direction for the improvement of the Villages and the ways for activation of the Villages. I really expect these suggestions of mine to make active contribution to make the actual plan through the promotion of the Rural Experience Tourism Villages.

The environmental pollution by noise is recognized by the pollution source made it not only to carry out harm of the Quality of a life of people seriously in most countries, but was generated for most actual problems. The measure to such environmental noise must conduct first investigation which noise generating currently regarded as questionable says in what grade has resulted and the suitable measure by that is studied. The concern of the residents who demand such a comfortable living environment is increasing rapidly. Therefore, the three areas of Jeollabuk-Do judged that noise is comparatively severe was selected. It is going to grasp delicately the noise actual condition of a residential, semi-residential, commercial, industrial area.

This paper describes the investigation into the actual condition of electrical equipments installation and management for establishing the countermeasures against the electric shock in submerged underground. The investigation was carried out for 27 underground premises in conurbation including Seoul, and potential of the exposed electrical equipments negatively affecting on human safety when disaster occurs was measured. The objects to which measurement was carried out were as follows; electrical source; advertising lighting; power equipment. As a result, it was confirmed that potentials more than 230[V] were induced in some equipments. In addition, the electrical equipments installed in most conventional underground premises were left unmanaged.

The Certification system will be able to expect that effect of marketing and the corporate image rising, if the certification body guarantees the contents of certification against industrial technical advance and safety, environment and efficiency, quality when it is suitable in the standard which is provided. The certification system where the private organization operates but recently on the legal notarization outside is disordering and the trust regarding the certification falls and the objective and gist of origin are damaged. But recently the trust of certification has fallen and the objective and gist of origin are damaged. Because the non-government certifications are disordering. Also the damage of the consumers majority occurs but it is insufficient the investigation analysis against the present condition regarding a non-government certification system and the operation actual condition. So it is necessary the actual condition where the countermeasure against hereupon is urgent. In this study, we present the operation direction of efficient against non-government certification system through investigation and the analysis.

In this paper an Investigation into the actual condition of electrical equipments installation & management and check the problem of application to IEC60364 in korea construction by the electrical installation technical regulation. building equipments by the electrical installation technical regulation are almost same TT system but the electrical installation technical regulation does not contact with protective conductor(PE conductor). This study derive a problem and resent the solving method of problem causing does not fully understand of IEC60364, mix electrical installation technical regulation and IEC60364 by the actual condition of electrical equipments installation & management in korea.

The purpose of this study is to identify the fire danger of the electric radiant heating system and check the way how to use it and the problems that could be possible through a actual case. We carry out an experiment to identify the possibility of the fire in the similar condition of the actual fire case. The results of this study are as follows. It is a possible condition to fire if the air blast of the electric radiant heating system is blocked by some combustible materials such as plastic bags continuously. A temperature sensor and a residual current device are necessary to disconnect the power source. It is also necessary to attach a notice in front of the electric radiant hearing system that shows users the fire danger to forbid the possible fire. Fires could be happened by internal defects of the electronic products. However, we can also find many external reasons to happen fires. Therefore, we need to check all reasons to make fires in the scene of a fire.

This study was designed to investigate the correlation between the degree of knowledge in regards to the importance of oral health and the smile scores as well as the correlation between their actual oral conditions and smile scores. The author surveyed the knowledge and the actual oral health condition of the subjects, 150 high school students (80 males and 70 females), and their frontal pictures were taken when they had full smiles. After evaluation of the smiles of the subjects by five dentists, the results were analysed. This study showed that there was neither a correlation between the smile score and the knowledge of oral health nor the actual oral condition. The investigation showed that the actual oral condition and care was performed well even if there were some wrong answers in the questionnaire, which asked about proper oral health. In conclusion, the smile could be related to the repetition of the habit of smiling rather than being related to the knowledge of oral health or their actual oral condition.
