To estimate design floods for hydraulic structures, statistical methods has been used in the analysis of rainfall data. However, due to the lack of rainfall data in some regions, it is difficult to apply the statistical methods for estimation of design rainfall. In addition, increased uncertainty of design rainfall arising from the limited rainfall data can become an important factor for determining the design floods. The main objective of this study was to assess the uncertainty of the future design floods under RCP (representative concentration pathways) scenarios using a bootstrap technique. The technique was used in this study to quantify the uncertainty in the estimation of the future design floods. The Yongdang watershed in South Korea, 2,873 ha in size, was selected as the study area. The study results showed that the standard errors of the basin of Yongdang reservoir were calculated as 2.0~6.9 % of probable rainfall. The standard errors of RCP4.5 scenario were higher than the standard errors of RCP8.5 scenario. As the results of estimation of design flood, the ranges of peak flows considered uncertainty were 2.3~7.1 %, and were different each duration and scenario. This study might be expected to be used as one of guidelines to consider when designing hydraulic structures.

Purpose: This study was conducted on dental technicians to examine the problems of the dental laboratory registration system and devise a plan to improve it. Methods: For data collection, an online survey was conducted on 14,015 dental technicians registered in the Korea Dental Technologist Association as of October 2020. Among the collected 405 questionnaires, 391 data were used for analysis. Results: We found that dental technicians felt that the dental laboratory opening registration system was unfair. There were problems including the problem of the verification method of job performance, not acknowledging the difference in the job field, and the lack of understanding of the structure of work cooperation between dentistry and dental laboratories. Furthermore, it was recognized that the system was improved by reflecting the change in job area according to the change of the times. Conclusion: There is an urgent need to reorganize the legal system so that the dental technicians can have their professionalism and autonomy recognized while remaining faithful to the public interest of protecting the national oral health by revising the related regulations, thereby ensuring smooth work activities.

The problem of reconstructing three-dimensional models of people and objects from color and depth images captured by low-cost RGB-D cameras has long been an active research area in computer graphics. Color and depth images captured by low-cost RGB-D cameras are represented as point clouds in three-dimensional space, which correspond to discrete values in a continuous three-dimensional space and require additional surface reconstruction compared to rendering using polygonal models. In this paper, we propose an effective ray-tracing based technique for visualizing point clouds rather than polygonal models. In particular, our method shows the possibility of an effective rendering method even in mobile environment which has limited performance due to processor heat and lack of battery.

People are making efforts multilaterally to create agricultural landscape beautifully. Still in farming villages, however, large-scale facilities or houses are disharmonized with natural environment because of their outer colors, mostly primary colors, not considering natural environment. The main study is done on experts' color perception. Investigation about perception of color experts ' view according to the existence of the energy business based on the color to set the direction of the rural landscape in the future. The result of the study shows that the image of the rural area is not reflected well, and the symbolic color of the rural landscape is the reverse image according to the energy business. The rural village's image in the future, "Harmonious", "Natural", "Rural" were higher Figure. There were the most important and harmony with nature. Based on such future harmony with nature in the color planning The colors match and is expected to be the color within the scope. Lack of awareness in the current farming town scenery is unsatisfactory. Awareness about the need for further improvement was higher. Therefore, color according to a harmony with nature images in accordance with the type of farming model should be planned.

The ridership and transit systems are influenced by the expansion of metro-rail in Seoul metropolitan area. However, it has been difficult to measure its precise quantitative influences. Also effective policy implementations have been limited due to the lack of practical evidences. Thus an empirical analysis for an operating metro-rail is essentially required. In this regard, this study examines the impact of the Jungang line on transportation system, whose metro-rail block has been recently started new service. The main interest of this study is to find out the changes of ridership and to forecast the ridership changes by the metro-rail service. The results indicate that the effect on auto users is less than that of bus users. The auto demand is decreased by 33.3% and the bus demand by 66.6%. Additionally, its influence on Gyeonggi-do bus was greater compared with that on the Seoul bus. From questionnaire survey, this results could be confirmed. To sum up, the metro-rail gives less influences on auto users, while it gives greater influences on bus users.

Even though the similar land price zone is very important element in the public land appraisal procedure, the concept is implicitly described and applied into the actual land appraisal system. This situation makes it worse when applying for the automatic selection of a comparative standard land parcel. In addition, the division of similar land price zones requires the objective and reasonable process for improving ALPAS(Automatic land Price Appraisal System), which becomes an issue today. To solve the similar land price zone determination problem that is caused by the lack of objective numerical standard, this study proposed a similar land price zone determination method using a hybrid clustering technique. Results showed that this hybrid clustering method that applied into the test area could easily detect similar land price zones with considerable accuracy levels, which are verified with some test statistics and real comparative standard land parcels done by manually.

This study has developed the sex education contents including new natural family plan, concept and principle by receiving the opinions and advices from professionals and professors on sex education, by amending and supplementing existing teaching materials on sex, and examining the books related with sex education contents that reflect the request of teachers and students, and the lack of sex education teaching materials which have been the reason that needs of school sex education has been highly recognized but not vitalized. The developed sex education contents are 8 areas such as knowing my body right, caring my body, observing the ability of being pregnant, marriage, sexual intercourse, process of pregnancy, miscarriage, and sexual violence, 30 lower areas, and 105 detailed contents in their composition, and here are the results of analyses of the degree of request of nurse teachers and the students on them. The teachers showed highest request in the area of sexual violence(M =4.67), the next was my body care(M=4.44), knowing my body right(M =4.38), process of pregnancy(M=4.13), marriage(M=4.11) and sexual intercoursen (M=3.98), ways of judging the ability of being pregnant(M=3.88), and miscarriage(M=3.72) showed comparative higher request than normal. Not like the teachers, the students showed that they requested Marriage area as the highest need(M=3.04) and next was sexual violence(M=3.02), caring my body(M=3.00) to have been higher than normal. Process of pregnancy(M=2.99), Sexual intercourse(M=2.81), miscarriage(M = 2.77), observation of the ability of being pregnant(M=2.74), and knowing my body right(M=2.70) have been the requests lower than normal. This study showed that sexual violence, marriage, caring my body, were the items most requested by both the leacgers and students and in elementary school the development of sex education teaching materials on natural family plan suitable to the level of development of the children has been requested as it has had no inclusion of the concept of natural family plan, and the students in elementary school are concerned on indirect sexual contents related with physical health like regular exercise rather than direct sexual education contents including sexual intercourse. All these show that they are still so naive on sex. The sense of the teachers on sex has been connected with the level of achievement of sex education of the children as it has been the important cause of deciding the contents of sex education. Therefore the materials developed onesidedly by leaders without reflecting the needs or the preference of the students might be worries of bringing shameful. low quality and negative opinions on sex, and on the other hand the children might lose the concerns and interest on sex education, So the materials should be developed to have the contents of sex education coinciding with the request of the children.

Sesame(Sesamum indicum L.) is probably the most ancient oilseed crop known in the world. The seed of sesame is used in a variety of ways as food. The whole seed may be eaten raw, either roasted or parched, or fed to birds and stock. Sesame oil is used as a salad or cooking oil, in shortening, margarine and in the manufacture of soap. Minor uses are as a fixative in the perfume industry and formerly as a carrier for fatsoluble substances in pharmaceuticals such as penicillin. One of the minor constituents of sesame oil, sesamin, is used for its synergistic effect in pyrethrin insecticides, in addition of a small quantity of this substance markedly increases the effectiveness of fly sprays. The meal remaining after oil extraction can be used as and animal feed-stuff or as manure. In general sesame meal is considered to be equal to cottonseed or soybean meal as a protein supplement for livestock and poultry. It is especially high in certain amino-acids such as methionine, which is low in soybean meal, and thus can be combined with it or similar meal to form a more balanced ration. An attempt to summarize the literature review on quality improvement of sesame was made to discuss the accomplishments of the past and perspectives in the future. The reviews on quality improvement of sesame were mainly discussed in connection with the cultural practices and genetic informations in current status. The emphasis focussed on environmental variation of quality in cultural practices, such as harvest time, variety by location, climatic condition, fertilizer application, and growth regulator treatment. On the genetic variation of quality, it was discussed on variety background, mutation breeding, correlations, and inheritance of quality related characteristics. It also was discussed on relationship between quality and plant traits, storage condition or period, and seed coat color. Moreover, current research status were reviewed on some minor elements such as sesamin, oxalic acid, and trypsin inhibitor. As a results of the review, the lack of an effort to quality improvement in each utilization area was indicated as a problem area. More active efforts for the improvement of quality were also insufficient to incorporate the available genes for quality in breeding method or collection and analysis of breeding materials. Therefore, researches in the future would be recommended to emphasize on these problem areas.
