Geological terminology used in Korea which has been politically separated for the last 50 years, were compared. For this study, geological terminology used in 'Geology of Korea' published in North Korea (1996), 'Geology of Korea' published in South Korea (1999) and other geological publications were compared. Among the 1272 geological terminology used in North Korea, 49 are for geochronology, 201 for mineralogy, 199 for petrology, 257 for structural geology, 93 for paleontology, and 473 for general geology. Out of these geological terminology, 657 (51.7%) have the same pronunciation and meaning as those used in South Korea 370 (29.1%) are analogous words, and 245 (19.2%)cannot be understood because of differences in the means of expression. Differences in geological terminology used in the two Koreas are thought to be mainly caused by language used only in North Korea, different foreign language interpretation, different initial law application, new connecting word construction, and influence from different cultures.

Vegetation surveys were performed at 45 plots along 10 highways cut slopes in South Korea. Total floral inventory, species richness and exotic plant percentage were obtained within each plot. Life history and life form of each species appeared were analyzed. Community types were classified using hierarchical cluster analysis and detrended correspondence analysis and non-metric multidimensional scaling were conducted from vegetation matrix. 292 species of vascular plants were discovered and the number of natives and exotics were 226 and 66, respectively. There were no significant differences of species richness and exotic plant percentage between cut slopes and rest areas. Hierarchical cluster analysis indicated five clear vegetation associations in cut slopes and rest areas. Detrended correspondence analysis indicated that species composition of total and native plants were similar along the highway cut slopes whereas exotic plants were distributed differentially along the highway cut slopes. in non-metric multidimensional scaling, the studied sites were more separated from each other on the basis of their species composition than the results of detrended correspondence analysis with respect to total, native and exotic plants. The both ordination represented that exotic plants have not been made uniform yet on cut slopes and rest areas by highway corridor in spite of diverse chronosequences after highway construction termination (1 to 22 years). This study showed that the distribution of species composition in exotic plants was different and localized on cut slopes and rest areas of highway in this representative peninsula area of North East Asia and the invasion of exotic plants can retard the process of plant species homogenization.

The purpose of this study is to help the understanding the characteristics in the costumes of men and women throughout the overall acceptance process of 'Naewaebub' in the late 'Chosun Dynasty' in which the notion of 'Naewae' is more prosperous than any other period in Korean history. Originally the distinction between man and woman was not intended to display the high and the low but to show the mutual respect according to each duty. As time goes on, that ideal became gradually changed to heighten the man and lower the women especially in 'Han' period of China. There was the ideal of distinction in the ancient times in Korea. Until 'Koryo Dinasty' the community has the system of blood-tied that put together maternal and paternal. 'Karye' was introduced in the late 'Koryo Dynasty' and accepted to the stereotype of morale in the 'Chosun Dynasty' and there seemed to be 'Samgang' and 'Oryun' at once. Many restrictions was imposed to behavior in women like rules of prohibition in attending the temple and concealment of woman's face and was recognized to rule of distinction between man and woman. Confucian life custom has been settled to Korean society throughout the late 16th century and 17th century and there were some appearances in the housing construction which divide the residences of man and woman. The characteristics in the costume from the avoidance of opposite sexes are clear in the structure of clothes changed from similar style to different style. The examples of those characteristics are as fellows. The costume in man was developed to advanced 'Pyoun-bokkwan' and 'Pyounbokpo' as social action of man prospered. Meanwhile the trousers which had been the same in the man and woman were separated to different trousers between man and woman. The costume life style of woman was changed to using the a hair whirl, hiding the face in the street and overlapping the innerwear under the skirt which was extension of woman's closed life style in late 'Chosun Dynasty'.

Purpose: To identify characteristics of chronic fatigue, difference between the duration of fatigue and characteristics of chronic fatigue, and association between chronic fatigue and related factors in adults. Method: The subjects for this study were 180 adults who had experienced fatigue for over one month The measurement tools were the Revised Fatigue Scale by Chalder et al. (1993), the Visual Analogue Scale-energy developed by Lee et al. (1991), the BEPSI (Brief Encounter Psychosocial Instrument) by Frank & Zyzanski (1988), Zung's self rating depression scale (1965) and life style items including exercise sleep, drinking smoking and diet as developed by the researchers. Results : Those who complained of fatigue over six months experienced higher disturbances in their daily life compared to those who had suffered from fatigue less than six months. There were a significant correlation between severity of fatigue and depression (r=.46, p<.001), stress (r=.41, p<.001), and sleep (r=.20, p<.01) Statistically significant relationships were found between severity of fatigue and amount of exercise per week (F=3.79. p<.05) disturbed sleep (t=-2.66, p<.01), number of times awakened during the night (F=3.48, p<.05) types of drinking (F=2.65, p<.05), and diet regularity (F=5.83, p<.01). The construction of a multiple regression model revealed an adjusted $R^2$ of .27 with the depression score serving the major predictor variables for severity of fatigue. Men and people in the younger age group were more energetic than women and those in other age groups. Also married people experienced more fatigue than people who were single. divorced or separated. Conclusion: In nursing interventions for fatigue, medical personnel should consider sociodemographic characteristics of the clients, ways to reduce of stress and counter disturbances in daily life and develop strategies for a health promoting life style.

This paper presents the findings of an investigation of the fiber content variations in concrete being discharged from a ready-mix truck at the construction site. Concrete samples were extracted from the truck drums at the beginning, middle and end of discharge. Subsequently, fibers in each sample were separated from the concrete, and weighed. Presumably, synthetic macro fibers will float towards the top, i.e. towards the drum opening, of the inclined, revolving truck-drum, while, on the other hand, steel fibers will tend to gravitate towards the lower parts of the mixer drum. Accordingly, the discharge batch, containing synthetic macro fibers, will contain a higher amount of synthetic fibers per unit volume at the start of discharge than the average unit volume fiber content of the mix, and the content will gradually decrease further down the batch. The discharge batch of steel fiber concrete will contain fewer fibers per unit volume at the start of discharge than the average unit volume fiber content of the mix, and the content should gradually increase further down the batch. The correctness of the foregoing is partly confirmed. A certain percentage of the truck loads did not comply with the proposed requirements, mainly steel fiber reinforced batches, indicating the necessity of a code or guideline amendment. A change in the Norwegian shotcrete directive was made in 2011, based upon experimental research work (2010), which, in combination with the subsequent University of Life Sciences report (2012), constitutes the foundation of this article.

Ozone has been a problem in big cities. That is secondary air pollutant produced by nitrogen oxide and VOCs in the atmosphere. In order to solve this, the first to be the analysis of the $NO_x$ and VOCs. The main source of nitrogen oxide is the road mobile. Industrial sources in Seoul are particularly low, and mobile traffics on roads are large, so 45% of total $NO_x$ are estimated that road mobile emissions in Seoul. Thus, it is necessary to clarify the relation with the activity of road mobile source and $NO_x$ concentration. In this study, we analyzed the 4 locations with roadside automatic monitoring systems in their center. The V.K.T. calculating areas are set in circles with 50 meter spacing, 50 meter to 500 meter from their center. We assumed the total V.K.T. in the set radius affect the $NO_x$ concentration in the center. We used the hourly $NO_x$ concentrations data for the 4 observation points in July for the interference of the other sources are minimized. We used the intersection traffic survey data of all direction for construction of the V.K.T. data, the mobile activities on the roads. ArcGIS application was used for calculating the length of roads in the set radius. The V.K.T. data are multiplied by segment traffic volume and length of roads. As a result, the $NO_x$ concentration can be expressed as linear function formula for V.K.T. with high predictive power. Moreover we separated background concentration and concentrations due to road mobile source. These results can be used for forecasting the effect of traffic demand management plan.

The measuring point of the Hangang Bridge affected by tide has some special topographic characteristics due to Nodle Island. Furthermore the submerged weirs located on the upstream and downstream. Therefore flow is separated and joined by Nodle Island. Discharge measurement at the point of the Hangang Bridge is very important, because Hangang Bridge is key station in managing the discharge and flood forecasting. In the past, it was too difficult to measure discharge in tidal conditions. HRFCO(Han River Flood Control Office) installed automatic discharge measurement facilities for solving this problem. Measuring equipments operates and measures discharge every 10 minutes at 2 points(southern and northern section close to Nodle Island), and calculates flow discharge using Chiu's velocity law(Chiu, 1988). In order to verify the results of automatic discharge measurements, manual discharge measurements were carried out by ADCP. In addition, the monthly discharge were also compared.

Background To construct a sophisticated three-dimensional framework, numerous modifications have been reported in the literature. However, most surgeons have paid little attention to the anatomical configuration of the concha and more to its deepness and hollowness, leading to unsatisfactory outcomes. Methods For a configuration of the concha that is definitely anatomical, the author further developed and employed the conchal bowl element, which has been used by several surgeons although the results have not been published elsewhere. The author constructed the conchal bowl element in one of three patterns according to the amount of available cartilages: one block, two-pieces, or a cymba bowl element only. A total of 20 patients underwent auricular reconstruction using a costal cartilage framework between 2009 and 2012. The 8 earliest reconstructions were performed without a conchal bowl element and the latter 12 with a conchal bowl element. The patients were followed up for more than 1 year. The aesthetic results were scored by evaluating characteristics involving the stability of the crus helicis, the conchal definition, and the smoothness of the helical curve. Results The ears reconstructed early without a conchal bowl element showed a shallow and one or two incompletely separated concha with an obliterated cymba conchal space. They also did not have a realistic or smooth curve of the helix because of an unstable crus helicis. However, ears reconstructed later with the concha bowl element showed a definite crus helicis, deep cymba conchal space, and smooth helical curve. Conclusions The construction of the conchal bowl element is simple, not time-consuming procedure. It is suggested that the conchal bowl element must be constructed and attached to the main framework for natural configuration of the reconstructed ear.

Baehuryeong tunnel connects Chuncheon with Hwacheon in Kangwon, Korea, This tunnel is a single tunnel with 5,057 m long and two bidirectional lanes which will be extended into low lanes in the future. The estimated construction period of Baehuryeong tunnel is approximately 55 months. This tunnel will become the longest bidirectional roadway tunnel in Korea. Compared to a twin tunnel, a bidirectional single tunnel has two major disadvantages with regard to the ventilation system and ease of escape during fire. For these reasons, a service tunnel and the transverse ventilation system are planned first time in Korea. In case of fire, the tunnel ventilation design aims to maintain a smoke free layer for passenger evacuation. The geology of Baehuryeong tunnel site is mainly composed of gneiss and granite. Baehuryeong fault is a mainly large scale fault which stands vertical and parallels with tunnel direction. The influenced zone of this fault is within 70 m. Baehuryeong tunnel was designed that it was separated with the distance of more than 100 m from Baehuryeong fault for its safety.
