As an exploratory study, the purpose of this study was twofold. First, to show the process for developing a pathfinder with for assessing how the end users analyze a pathfinder ("a usability test"). Second, to provide a pathfinder for fashion marketing fields. Organised especially for students of the Fashion Graduate School in Dongduk Women's University, this pathfinder included books, periodicals, Internet web sites, online stores, brands, and apparel organizations. Participants in the test evaluated the pathfinder with medium to high grade in terms of contents, classification, and quantity of resources. In particular, they acknowledged the usefulness of a pathfinder. The results could provide helpful guidelines for the design of pathfinders. In addition, this publication provides additional information that focuses on fashion marketing fields.

Congenital diaphragmatic hernia is an important cause of respiratory distress in the newborn. Eventration, with which these conditions are easily confused, may also Produce severe respiratory distress in infancy or be an asymptomatic radiographic finding. Harrington`s classification of diaphragmatic hernias into two categories, traumatic and nontraumatic, is most widely accepted. Nontraumatic hernias are [1] the congenital types, composed of the posterolateral [Bochdalek], those through the esophageal hiatus, the parasternal [/Morgagni], and those through a defect left by partial absense posteriorly, and [2] the acquired types, composed of those through the esophagea/hiatus [sliding and paraesophageal] and those the sites mentioned above under the congenital hernias. During the period from 1970 up to October 1978, 21 cases of diaphragmatic hernia were treated in department of cardiovascular and thoracic surgery. 11 cases of Bochdalek hernias, 1 case of Morgagni hernia, 5 cases of diaphragmatic eventration and 3 cases of hiatal hernia [2 cases of paraesophageal and 1 cases of sliding type], were experienced. 3 cases of 20 died of respiratory insufficiency, 2 cases of mortality were combined with left lung hypoplasia with Bochdalek hernia.

Site characterization for decommissioning Kori Unit 1 is ongoing in South Korea after 40 years of successful operation. Kori Unit 1's containment building is assumed to be mostly radioactively contaminated, and therefore radiation exposure management and detailed contamination investigation are required for decommissioning and dismantling it safely. In this study, site-specific Derived Concentration Guideline Levels (DCGLs) were derived using the residual radioactivity risk evaluation tool, RESRAD-BUILD code. A conceptual model of containment building for Kori Unit 1 was set up and limited occupational worker building inspection scenario was applied. Depending on the source location, the maximum contribution source and exposure pathway of each radionuclide were analyzed. The contribution of radionuclides to dose and exposure pathways, by source location, is expected to serve as basic data in the assessment criteria of survey areas and classification of impact areas during further decommissioning and decontamination of sites.

In the Web 2.0, besides more gaining information on the web, the number of web sites that take advantage of RSS increases explosively. Commonly each users search RSS channels through the web search engine before registering RSS channel's url to the RSS reader. Users judge whether the site is RSS channel or not and register an RSS channel's url through theirs interests. Because accomplished by users themselves, those processes conflict to user's convenience and quick consumption of information. Techniques of current search engines can't provide users with reliable RSS feed information as search results. In this paper, we analysis appropriateness of current search engines' techniques that offer users RSS feed search service and discuss their limitations. Also, we make up RSS feed database through classification of RSS tag being possible to search RSS feed information effectively and apply update rate of each RSS channel's feed to ranking algorithm providing more reliable search results.

The purposes of this study were to determine an algorithm for estimating agricultural water demand of remote sites using remote sensing data and to apply it to Hwanghae South Province and estimate the present and potential water demand for agriculture use. 3 Landsat-5 TM images and DEM(100${\times}$100mm) were used for classification of the existing land cover and land suitability analysis for paddy fields. Also, 20 years meteorological data of North Korea were used for calculating the potential evapotranspiration by Blaney-Criddle eq. and net water demand. The results showed that the present and potential agricultural water demand and the developable area for paddy fields is about 89,300㏊.

This study is to provide the useful data for the design and construction of the geotechnical engineering works by collecting and analyzing the soil properties of granite soil in the Kangwon Province. Data base was obtained from 92 field sites in the Kangwon province divided into 15 areas based on administration district. Total numbers of data were 478. Correlations between soil constants, especially compaction properties, were obtained by performing statistical analysis. Analyzed results were as follows. 1. Most of granite soil consists of SM and GM based on United Soil Classification System. 2. Mean gravity of granite soil is 2.65 3. High correlations between optimum moisture content and the maximum dry density, plasticity index and liquid limit are obtained. 4. Analyzed results between other soil constants show relatively low correlation. However, they show consistent trends matchable to geotechnical engineering senses.

The dosal sites of 61 Koreans were exposed to increasing UVB doses in the 10mJ/$\textrm{cm}^2$ interval from 10mJ/$\textrm{cm}^2$ to 100mJ/$\textrm{cm}^2$ by solar-simulator, and at the 24hr after UV-B exposure we determined the first MED (Minimal Erythema Dose). For the precise measurements, we peformed the second exposures arround the first MED with 2.5mJ/$\textrm{cm}^2$ interval. The mean MED of all volunteers was 39.6 $\pm$ 15.7mJ/$\textrm{cm}^2$. As the distinction of sex, the means of male and female were 46.9 $\pm$ 18.1mJ/$\textrm{cm}^2$ and 31.5$\pm$8.5mJ/$\textrm{cm}^2$ respectively. According to the classification of skin type by Greiter. F.(1), the percent of skin type I to Ⅵ were 10.9%, 36.4%, 34.6%, 12.7%, 3.6%, and 1.8% respectively.

The purposes of this study are to investigate perceived discomfort for static joint motions, and to propose rankings for the joint motions based on the perceived discomfort. The perceived discomfort was measured through an experiment using the free modulus method of the magnitude estimation, in which ten healthy college-age female students participated. The results showed that joints, joint motions and their levels significantly affected the perceived discomfort at $\alpha$=0.01, and that the interaction of joints and joint motion levels was also significant. Based on the experimental results, three rankings were proposed by joint and joint motions, by joints and by joint motions, which were very different from the existing ones. Especially, the proposed rankings were different from the males' published before in their order and magnitude. These rankings can be used as a valuable tool for better understanding potentially adverse effects of poor working postures in industrial sites, and as basic data for developing the postural classification scheme.

In order to support wind power development, the wind resource database of Jejudo has been established by meteo-statistical analysis on meteorological-mast measurements of KIER. Analysis processes contain correlation of monthly wind speed and power-law exponent among neighboring sites, Measure-Correlated-Predict for long-term correlation, classification of exposure category using satellite image and so forth. It is found that the monthly variations of wind speed and power-law exponent depend on seasonal winds and characterize wind system of Jejudo.

The H/V ratio (Horizontal to Vertical spectral ratio) has been used to infer site amplification without previous knowledge of near-surface geology and in fact may provide useful general site condition information. This method is used to classify the site characteristics of seismic stations in Korea by comparison with known H/V ratios representative of various sites all over the world. In addition, differences between horizontal and vertical kappa values were evaluated for each seismic stations by comparing WV ratio and Weak Motion amplification derived from inversion of stochastic ground motion parameters and were used as index to quantitatively classify the site characteristics.
