Significant soil erosion and water quality degradation issues are occurring at highland agricultural areas of Kangwon province because of agronomic and topographical specialities of the region. Thus spatial and temporal modeling techniques are often utilized to analyze soil erosion and sediment behaviors at watershed scale. The Soil and Water Assessment Tool (SWAT) model is one of the watershed scale models that have been widely used for these ends in Korea. In most cases, the SWAT users tend to use the readily available input dataset, such as the Ministry of Environment (MOE) land cover data ignoring temporal and spatial changes in land cover. Spatial and temporal resolutions of the MOE land cover data are not good enough to reflect field condition for accurate assesment of soil erosion and sediment behaviors. Especially accelerated soil erosion is occurring from agricultural fields, which is sometimes not possible to identify with low-resolution MOD land cover data. Thus new land cover data is prepared with cadastral map and high spatial resolution images of the Doam-dam watershed. The SWAT model was calibrated and validated with this land cover data. The EI values were 0.79 and 0.85 for streamflow calibration and validation, respectively. The EI were 0.79 and 0.86 for sediment calibration and validation, respectively. These EI values were greater than those with MOE land cover data. With newly prepared land cover dataset for the Doam-dam watershed, the SWAT model better predicts hydrologic and sediment behaviors. The number of HRUs with new land cover data increased by 70.2% compared with that with the MOE land cover, indicating better representation of small-sized agricultural field boundaries. The SWAT estimated annual average sediment yield with the MOE land cover data was 61.8 ton/ha/year for the Doam-dam watershed, while 36.2 ton/ha/year (70.7% difference) of annual sediment yield with new land cover data. Especially the most significant difference in estimated sediment yield was 548.0% for the subwatershed #2 (165.9 ton/ha/year with the MOE land cover data and 25.6 ton/ha/year with new land cover data developed in this study). The results obtained in this study implies that the use of MOE land cover data in SWAT sediment simulation for the Doam-dam watershed could results in 70.7% differences in overall sediment estimation and incorrect identification of sediment hot spot areas (such as subwatershed #2) for effective sediment management. Therefore it is recommended that one needs to carefully validate land cover for the study watershed for accurate hydrologic and sediment simulation with the SWAT model.

Jie Jie Hao Yin 『절절호음(節節好音)』 is a script collection produced during the Qianlong's ruling Period which had one of the most flourished period of Qing Dynasty's Palace Drama. This script collection is consisted of 86 scripts of 6 Festival Court Plays: New year's day (元旦), Lantern festival(上元), Yanjiu festival(燕九), Snow appreciation(賞雪), Day of Kitchen god worshipping(祀竈), New year's eve(除夕). These scripts are effective records to study the New Year's Eve Drama of Qianlong Period. Jie Jie Hao Yin carry out the performances not only through Kunqiang (崑腔), and Yiyang Tune (弋腔), but also through various types of entertaining performances such as dance, masque play, puppet show, and story telling. Most of the songs were sung by various gods praising the era of peace as the holiday approaches. In the contents of revealing the luck to be brought by the holidays, it sought for the colorful transformations of stages through adding humoristique short stories or various feast genres in between the performance. It also tries to seek for diversities of stages through active application of acrobatics. It also portrays folk customs from BaiYunGuan's temple fair, Yanjiu Festival in YanBin, the Lantern Fair of Lantern Festival, and various activities of wet markets from New Year's Eve from diverse points of views. Especially through various shows and Chinese folk-art forms, the popular folk activities and entertainments near Beijing in the beginning era of Qing Dynasty can be observed. Jie Jie Hao Yin is a very important resource to look at the popular art activities of Beijing during Qianlong Period, and how the Palace culture accepted the folk cultures and applied to its own advancements.

Purpose: The purpose of this study was to examine factors influencing new graduate nurse turnover. Methods: This study was carried out as a secondary analysis of data from the 2010 Graduates Occupational Mobility Survey (GOMS). A total of 323 nurses were selected for analysis concerning reasons for turnover. Data were analyzed using descriptive statistics and multilevel survival analysis. Results: About 24.5% of new nurses left their first job within 1 year of starting their jobs. Significant predictors of turnover among new nurse were job status, monthly income, job satisfaction, the number of hospitals in region, and the number of nurses per 100 beds. Conclusion: New graduate nurses are vulnerable to turnover. In order to achieve the best health of the nation, policy approaches and further studies regarding reducing new graduate nurse turnover are needed.

Standards are increasing of importance for New & Renewable energy. The rapid growth of production is one reason for this but standards are equally important in ensuring the quality and reliability of installed New & Renewable energy systems, which have a propound impact on acceptance of the technology in the expanding marketplace. Korea government (Korea Agency for Technology and Standards, KAIST)make and implement a five year plans for promotion of international standardization of this field from 2004. KATS leads the technology innovations and eventually increases the international competitiveness. Strategic collaboration with other countries is also strengthened through Korea's participation in international standards and conformity assessment system such as IECEE(IEC system for conformity and certification of electrical equipment). One of the major goals of the Plan is to facilitate trade between Korea and its trading partners by emphasizing harmonization of its national conformity assessment system with international norms.

Masks are a portable functional product for daily use. They can protect user health by filtering harmful fine particles in the air. In the past decade, there have been approximately 10 yellow dust incidences per year, amounting to a total duration of 20 days, and they continue to increase year after year. In addition, the frequency of yellow dust incidences in Korea has increased by more than four times compared to levels from the 1970s. Statistical reports indicate that annual damages caused by yellow dust amount to more than six trillion KRW. This study developed a zero-fog multi-layer mask with a collection efficiency and yellow dust and particulate matter filtration areas that are at least thrice as effective as existing masks. The new mask also reduces pressure drag by half.

Design subjects have become popular in the engineering education. In these subjects, an active learning skill was introduced to students. Students have to decide a theme and the way how to study it and to find answers by themselves. This learning method was developed in the early year courses in the University of Tokushima. The common learning curriculum among whole university adopted this design subjects from 2005 of the school year and eleven more new subjects started. "Roots finding" is one of them and the objectives are to gain abilities of self-study through the research on a particular subject, and make report then presenting them. Self-learning ability, research ability and presentation skills were enhanced through this subject.

The population dynamics of Ecklonia stolonifera was investigated at Tongyeong coastal area in the South Sea of Korea. The blade length and width, stipe length and diameter, mean total length and mean weight were measured from randomly collected fifty individuals in every month. The plants in Tongyeong population were relatively bigger than those of Busan Korea and Aomori Japan in terms of their blade length and width. The population biomass was low in winter and high in spring and summer. The sporangial sori were found from August to December but prominent in September and October. About 90 % of the Tongyeong population was consisted of one- and two-year old plants and the zoosporangial sori were observed mostly in two-year old plants. It was different from the results of Busan and Aomori population in which the zoosporangial sori were observed from the plants older than three years. The new populations were developed from the zoospores of two-year old plants and their generation time was relatively shorter than those of Busan and Aomori.
