All Korean professional engineer′s great joy Is to welcome the Japanese professional engineers and relevant guests to the 1987 Japan-Korea Professional Engineers Joint Convention organized by the Korean Professional Engineers Association. As there exists an effort of blood, sweat and tear behind a succeeded theatrical stage, so an exquisite devotion with drawing up a master plan, investigation, supervision and etc by engineering firms is soaked through every part of huge construction projects and large unit factory buildings. It is over 14 years that the Engineering Service Promotion Law has been enacted by the Ministry of Science and Technology. In the meantime, the domestic engineering (engineering service) have reached a remarkable higher level while the number of engineering firms participating in overseas market has gradually been increasing. From a small scale of under water investigation to a large scale planning of atomic reactor or petrochemical plant, engineering service business can be said "The Software of Total Industry." Engineering service is what is called a higher business which offers specialized engineering know-how and experience. Engineering service compaines offer Its specialized knowledge and experience to government, industry and commerce. Whether the task is to modernize plant equipment, to design a building or to manage construction, an engineering company will develop and implement the most appropriate and cost effective solution. Clients use the engineering service of firm knowing that the engineer′s professional judgement is not influenced or biased by other commercial affiliations. While benefiting from the diverse experience that professional engineers can apply to a specific problem, government and industry also reduce the need for permanent in-house engineering staff. Engineering firms may be specialized or multi-disciplinary.

In this paper, we suggest a new spatial information system called video GIS where video is used for spatial data construction and is integrated with map. We develop a prototype system of video GIS and apply it to roadside facility management. The main functions supported by the suggested system are data collection, coordinate calculation and conversion, data construction, analysis, searching, and browsing. The stereo images and corresponding position data are collected by a vehicle named 4S-Van that has GPS, IMU, and cameras. The 3-D coordinates of the objects in the images, such as road sign, signal lamp, and building, can be calculated and constructed from the collected data. The spatial objects are displayed on both image and map, and can be searched and browsed, which enables visual and realistic browsing and management of spatial objects. Compared to conventional field survey used in roadside facility management, the method enables faster, easier, and more efficient construction of spatial data. The suggested video GIS can be applied not only to roadside facility management but also to many similar projects of central or local governments that are related to GIS.

The nuclear power plant(NPP) construction is a mammoth project, which requires a huge construction budget and the long construction duration of about 7 years. Recently there is a trend to shorten the construction period, to save the construction cost and to ensure the competitiveness through adopting the open top construction method. In this method, the major equipment are moved into the building through its top, and the internal works of the reactor building are being in process without installation of a dome roof.

Application of structural load on soft ground can cause lateral movement as well as ground break due to pressing and shearing of ground. Especially, abutment supported by pile foundation can make pile deformed due to lateral movement of ground in order to have harmful effect on structure. According to the result of this study, it is required to consider disturbance of weak soil layer when using lateral movement countermeasure method by EPS construction method as a result of performing study on safety review and EPS construction method with respect to this based on site where lateral movement occurs due to backside soil filling load at bridge abutment installed on weak ground, and it is required to sufficiently consider soil reduction during design of EPS construction method due to lateral movement deformation of soft clay layer by losing ground horizontal resistance force due to plasticity of ground around pile as well as combination part damage with pile head and expansion foundation.

As the Deep Cement Mixing Method is composed of drilled natural soft soil structure and injected cement slurry to be mix together in it, the nature of excavated ground is influenced directly to the application of constructability. Also the nature of in situ soil is the main material, the mix design and construction work plan should be established before the investigation of soil which is performed through the whole site confirm the soil parameter before construction. The nature of investigated soil and water level as should be performed accurately.

The purpose of this study is to compare and analyze how many species of trees presented with scientific names are on the written test for engineer landscape architecture, as their usage has increased in the landscape industry in recent years. The following is the result of comparing and analyzing the species of trees which are frequently used in landscape, planting construction, and the scientific name questions presented in the previous 6 years by year on the written test for engineer landscape architecture. First, the results of analyzing the examination question frequency by year in the landscape planting subject showed a gradually declining trend from 2014 after peaking at 56.6% in 2013. Second, 163 species of trees using scientific names were presented in questions on the written test for engineer landscape architecture over the previous 6 years and these included Betula platyphylla, Sophora japonica, Cercis chinensis, Taxus cuspidata. The number of species of trees used in landscape construction during the same period was 169 including Pinus densiflora, Chionanthus retusus, Cornus officinalis, Syringa dilatata. The result of interviews with landscape planting construction officials showed that when choosing the species of trees, they emphasize ecological characteristics, such as the ratio of trees to shrubs, flowers and autumn leaf characteristics, and also consider the morphological characteristics, landscape characteristics, economic feasibility, and the supply and demand situation. Third, it was found that 70 (42.9%) out of 163 species of trees presented with scientific names on the examination were not used in landscape planting construction and 76 (44.9%) out of 169 species were not used as material for questions. As for the scientific name questions, deciduous trees and evergreen shrubs accounted for the more questions, Evergreen and deciduous tree and shrubs were most common in landscape planting construction as well.
