우리나라의 고속도로는 1968년 2월 1일 경부고속도로를 착공한 이래 꾸준히 증가하였으며 2002년 현재 2,637km가 건설되었다. 이는 전체 도로 연장(91,396km)의 약 2.9%에 해당한다(표 1 참조). 고속도로는 그림 1에 나타낸 바와 같이 1990년 이후 급격히 증가하였으며, 앞으로도 계속 증가하여 2004년까지 약 3400km, 2020년까지 남북방향으로 7개축(3,291km), 동서방향으로 9개축(2,869km)의 7$\times$9 간선도로망을 목표로 총 6,000km 이상이 건설될 예정이다.(중략)

지난 1984년 개통된 88올림픽 고속도로는 '전라남도 담양군'과 '대구시 달성군'을 연결하는 고속도로로 동서교류를 확대하는 큰 역할을 하고 있다. 하지만 현재는 국내에서 유일한 왕복 2차선 고속도로인 것은 물론 중앙분리대가 없는 유일한 고속도로로 유명하다. 즉 늘어나는 교통량을 감당하지 못하고, 안전성에도 문제가 있는 것이다. 때문에 현재 88올림픽 고속도로가 포함된 제12호선 고속국도에서는 왕복 4차선으로의 확장공사가 한창 진행 중이다. 오늘의 주인공인 (주)포스코건설은 고속국도 제12호선의 담양~성산 간 확장공사 제3공구 현장을 책임지고 있다. 확장공사가 이뤄지는 목적이 고속도로 운전자들의 안전성 제고에 있는 만큼 이곳에서는 그 취지가 무색해지지 않게 근로자들의 안전을 최우선 가치로 여기고 있다. 이곳 현장에서 어떤 안전활동이 전개되고 있는 지 찾아가 봤다.

Gyeongbu and Namhae expressways in the country, are the major arterial highways which are connected with the Busan port in the north-south and east-west directions, respectively, and required to study the traffic characteristics about the hourly volume factors(K-factor) by concentrated midium-size and large-size cargo trucks of 20% or higher in expressways. We therefore attempted to predict the K-factor in expressways through the correlation analysis between K-factor and K-factor estimates on the basis of the short-term VDS data collected at the basic segments of the above major expressways. As a result, power model appeared to be appropriate in predicting K-factor by the K-factor estimate based on VDS data for 7 days with a high explanatory power and validity.

Current state of population, the existing roads, and the function of roads and highways of North Korea have been reviewed in this paper. In addition, the 'Five by five' road network has proposed for North-South and East-West directions to be connected with the road network of South Korea, China, and Asian Highways. Furthermore, the evaluation criteria and weighted values have suggested to determine the investment priority of highway based on the survey results from expert group members using AHP analysis method. Throughout the analysis, the ranking of the investment priority has been decided for the North-South axis and East-West axis. The second North-South axis (Geasung-Pyungyang-Anju-China) has been ranked as the first priority for the North-South axis followed by the fifth North-South axis as the second, the first axis as the third, the third axis as the fourth and the fourth axis as the last priority. For the East-West axis, the second East-West axis(Nampo-Pyungyang-Wonsan) has been ranked as the first priority followed by the first axis as the second, the third axis as the third, the fourth axis as the fourth and the fifth East-West axis as the last priority.

The surveyed area is mainly distributed by the sedimentary rocks, tuffs, and esites in Cretaceous age and acidic and basic dikes are intruded in these rocks. The principle discontinuities are represented by beddings, joints and faults. The trends of the beddings of sedimentary rocks develop as E-W direction in the start area. However, they are gradually bending and finally their trends are N-S direction in terminal area. In the sedimentary rocks the 3∼4 joint sets are distributed and in dikes joints are more scattered. The majority of joints are highly dipped. Sampo fault which has NE-SW trend makes a valley and NW trending normal faults are well developed at 50k+600 to 51k+000 area. During the construction of tunnel the orientation of discontinuities will not significantly influence on the stability of excavation. Since the rock mass is extensively jointed, the overbreak in tunnel wall may be placed.

This research is to suggest an ecological management methods by classification of biotope type and its mapping for Tricholoma matsutake. The target area was construction site of the East Hongchun - Yangyang Highway (Yangyang section) where massive production of Tricholoma matsutakes is in place. Specifically, the 700 m long range of area around the road route, Yangyang section, which is over a total area of $19,79km^2$. The flow of this research was as follows: first studied were the characteristics of the Yangyang Tricholoma matsutakes; second, reviews on previous studies on Tricholoma matsutakes; third, the formulation of standards and processes of biotope type considering Tricholoma matsutake production; and fourth, mapping of biotope considering the production area of Tricholoma matsutake. In 24.77% of the region, slope angle measured $30{\sim}40^{\circ}C$, which is suitable for Tricholoma matsutake production. Also, 17.44% of the region had southward vegetation structures, and as for the Pinus densiflora; 26.00% had average receipts; the tree ages was $38{\pm}8.34$ years; and the average density of canopy layer was $9.55{\pm}4.89/100m^2$. The soil acidity (pH) values of 5.0 to 5.6(47.96%) > 5.6 to 7.0(42.90%) > 4.0 to 5.0(9.14%) were slightly high for Tricholoma matsutake growth; but 57.10% of the area had a soil pH of 4.0-5.6. The organic horizon (A0 layer) was $3.39{\pm}2.14cm$, and the mean depths were 4-6cm(78.03%) > 0-2cm(18.10%) > 2-4cm(3.87%). Based on the results of previous studies and field researches on the presence of vegetation (the pine dominance ratio), the topographic structure (the terrain characteristics and slopes), the receipt, the soil structure (the soil acidity and the organic layers interposed between the depths), and the vegetation density, six clusters based on the identified types of biotopes are produced in this paper. Area of distribution according to the type of biotope was Tricholoma matsutake of the potential-production (II) biotope (32.86%) > Tricholoma matsutake of the inadequate-production biotope (22.17%) > Tricholoma matsutake of the adequate (II)-production biotope (17.79%) > Tricholoma matsutake of the adequate (I)-production biotope (14.86%) > Tricholoma matsutake of the potential-production (I) biotope (9.77%) > Tricholoma matsutake of the produced biotope (2.55%).

The Misiryeong East-West road opened in July 2006, after the opening of the Expressway between Seoul and Yangyang in June 2017, has led to a recession caused by a decrease in the number of visitors to nearby region, leading to the emergence of economic crisis in the surrounding region. Against this background, in order to revitalize the Healing Road in Misiryeong, we study to find a way to revitalize the region by creating a landmark in Ulsanbawi Rock. In order to create a landmark of Ulsanbawi Rock, an observation cafe, exhibition facilities, and convenience facilities were built, and a monorail was used to view Ulsanbawi Rock, and a healing plaza, resting area, and outdoor performance hall were installed to promote the local economy.
