Purpose: The purpose of this study is to examine decision factors to start orthodontic treatment with male and female undergraduates having experience in orthodontic treatment at a dental clinic or hospital because of malocclusion. Methods: A survey was carried out to investigate decision factors to begin orthodontic treatment with 330 male and female undergraduates attending universities located in Daegu Metropolitan City or Gyeongsangbuk-do who had experience in orthodontic treatment at a dental clinic or hospital because of malocclusion, and out of 330 questionnaire sheets, total 294 (89.1%) sheets were employed for analysis after excluding ones unreliably or erroneously answered. Results: According to the results of analyzing decision factors for orthodontic treatment, such factors as 'a dentistry-related person's suggestion', 'feeling necessity on one's own' are found to be significantly higher in students majoring in health units than those having non-dental health majors, and students residing in small and medium cities are influenced more significantly by this decision factor, 'an acquaintance's suggestion', than those living in farming and fishing villages or big cities, and students who started orthodontic treatment at elementary school were more significantly influenced by the factor, 'feeling necessity through the public media'. Conclusion: Among the factors influencing their decision on orthodontic treatment, no influence was found in sexual difference, and each of the decision factors influenced them considerably according to the difference of their residence, economic power, majors, or time to start orthodontic treatment.

Purpose: After Mers breakout in 2015, major hospital in Korea have been renovated the emergency department to make a separate infection control zone for high-risk patient with potential infection and to improve a triage area and an entrance area for efficient patient evaluation. However, there are no specific design standards to reinforce infection control for patients and staffs safety. Therefore, it is important to establish of initial design factors in the triage and entrance area as a guideline. Methods: 5 cases which had been recently renovated are selected to analyze patient circulation and spatial composition in a triage area and an entrance area. The partial floor plans of each case are represented as bubble diagrams to help understanding of different patient circulation flows. Based on this analysis, significant design factors which should be considered in planning stage for infection control have been extracted. Results: 13 design factors are established. Using these design factors, patient circulation diagram is generated to provide an optimized suggestion for efficient infection control. Implications: This suggestion provides basic databases to start to establish design guideline in the triage area and the entrance area to minimize infection spreading in the emergency department.

In generally, the estimation work regarding building mechanical service system in comparison with other architectural estimations is time-consuming, and the process is continuously getting more difficult because of the increased usage of the attached piping materials such as fittings and supports in addition to their complicated construction processes. In order to improve this problem, the Korean authority provides a simple method to estimate the attached material rate regarding the main piping material, which is the most time-consuming work in the architectural mechanical estimation. However, to be an applicable method on construction site, a proper conversion rate of the attached piping material is still required for the proposed method regarding building usage and working types. Therefore, the purpose of this research is the suggestion of the material and labor cost rate of the attached piping materials such as the fittings and supports by work types and fitting methods of indoor fire, sprinkler, and extinguishing gas piping work of mechanical fire protection facilities in office buildings that have been designed after 2010.

The government's financial subsidy system for the construction project of urban rail transit needs to be revised. In 1998, the central government raised its subsidy rate to 50$\%$ of the total cost of construction. The 'method for differentiating subsidies depending on construction type and transit System' is suggested here, so that a subsidy rate can be raised for the construction of Light Rail Transit, which costs less to construct. Such methods will force local governments to make decisions regarding construction method and project size in a more rational manner.

Deep excavations in the urban areas have been frequently going on in large scale. Soil-nailing and Earth-anchor supporting methods are generally used in deep excavation. These construction methods cause ground disturbances during drilling process, and damages of adjacent structures and ground due to the differential settlement throughout construction period, and unexpected behaviors of supporting system according to the characteristics of drilling machine and ground condition. This article introduces two actual examples of adjacent deep excavation for the construction of university buildings in granitic Seoul area. The important results of construction and measurements obtained using Crawler drilling machine for Soil-nailing and Earth-anchor supporting methods are summarized. And some suggestions are given to improve and develop the technique of design and construction in the deep excavation projects having similar ground condition and supporting method.
