History education is of growing significance in relation with minority group's identity issue in an irreversible trend of globalization. Archives and the cultural institution can be a major player in the reforming the history education as conducted in Britain. This paper deals with the Moving Here project led by The National Archives. The vision of the project is to overcome barriers to the direct involvement of minority ethnic groups in recording their own history of migration and to ensure this history is passed on to the next generation through schools. More than 200,000 digitised images and documents in the Moving Here have been selected from the 28 content partners' collections. In addition, TNA and the regional partners worked with minority ethnic groups to record their culture and stories. In doing so, real and lasting relation between the community and the ethnic groups has developed. The outputs of the project such as films and stories were distributed free for regional schools. The School section of the Moving Here provides a range of education resources. One of the most impressive outcome of the project is the minority's desire to have their own archives for identity and self-esteem.

This paper researched a study to find a combination of acquisition scores for 9 dart throws, which is the minimum number of dart tactile throws in 501 point dart games. The maximum score that can be obtained by throwing once in a dart game is 60 points, which can end the perfect dart game with 60 points eight times according to 60×8+21×1=501, and if you earn 21 points once, you can finish the game with 9 throws. This is called 9-dart finish. As such, only 18 and 14 studies on the combination of scores that can obtain 501 points with 9 throws are known, and no studies have been conducted applying the exhaustive search algorithm. This paper proposed a division branch-and-bound algorithm as a method of simplifying the O(2ⁿ) exponential time performance complexity of the typical branch-and-bound method of a exhaustive search method, to polynomial time complexity. The proposed method limited the level to 8, jumped to a quotient level of 501/60, and backtracked to explore only possible score combinations in the previous level. The possible score combinations of the nine perfect games found with the proposed algorithm were 90(101 cases).

This study suggested a method of forecasting market-share of each mode after introducing new urban rail transit lines. The study reflected the observed market share of presently operating urban rail transit into forecasting process in order to improve accuracy in predicting market share of each modes. For more realistic representation of the forecasting model, we categorized O/D pairs according to attributes of trip distance, access time and number of transfers. The analysis results of traveler's mode choice behavior with observed data showed that the trip distances are longer, the share of urban rail tends to be higher, and that the number of transfers is fewer and the access times are lesser, the share of urban rail also tends to be higher. Then, incremental logit model was used in estimating mode choice probabilities for O/D pairs along with rail transit lines while utilizing observed market shares of each modes and differences in transit service level. As the next step, the market share of rail transit after introducing new rail transit lines was forecasted by using incremental logit model with the intial share values calculated the previous analysis step. It also reflected changes in level of service for automobile in highway due to changes in highway systems and changes in mode shares after introducing new lines of rail transit. It can be expected that the proposed method would more realistically duplicates phenomena of mode choice behavior for rail transit and that it would be more theoretically logical than the typical existing methods using SP data and incremental logit model or using addictive logit model in this country.

Previous research has recently shown that non-cognitive factors such as attitudes toward statistics contribute positively to statistics learning, Hence, helping students develop positive attitudes toward statistics has become one of the essential goals of statistics teaching. A wide variety of instruments assessing attitudes toward statistics were developed and validated in foreign countries, but not many in Korea. The SATS-36(Survey of Attitudes Toward Statistics-36; Schau et al., 1995) has been regarded as one of the most valid measures of attitudes toward statistics. Therefore, this study was designed to validate a Korean version of Survey of Attitudes Toward Statistics(K-SATS). Instead of six factors of the original scale, a five-factor structure including interests, value, cognitive competence, difficulty, and effort was empirically supported by the Korean student sample. The results evidenced high reliability and construct validity of K-SATS. In addition, students' attitudes towards statistics differed across gender, level of statistics courses, degree programs, and major. These findings were discussed in terms of their implications for future research and statistics teaching.

Air pollution associated with the $NO_x$ emission from the ship engines is becoming one of the major environmental concerns these days. As the regulations on ship pollutants are strengthened, the wet absorption method, for controlling complex pollutants in a confined space, has the advantage of simultaneously removing various pollutants, but the low solubility of nitrogen monoxide is drawback. In this study, for improving existing denitrification scrubber system, NO oxidation process by hydroxyl radical produced from irradiating UV light on $H_2O_2$ is suggested and the $H_2O_2$ decomposition rates and hydroxyl radical quantum yields were measured to find the optimum condition of $H_2O_2$ photolysis reaction. As a result, the optimum quantum yield and photolysis rate of $H_2O_2$ were 0.8798, $0.6mol\;h^{-1}$ at 8 W, 2 M condition, and oxidation efficiency of 1000 ppm NO gas was 40%. In batch system, NO removal efficiency has a range of 65.0 ~ 67.3% according to input gas concentration of 100 ~ 1500 ppm. This results indicate that the scrubber system using hydrogen peroxide photolysis can be applied as air pollution prevention facility of ship engines.

In Japan, a country renowned for her traditional respect for handicraft, superior craft techniques have been transmitted from generation to generation. Modern Japanese textiles reinterprete these traditional techniques in a new light and combine them with modern technology, to make modern Japanese industrial textile both futuristic and traditional simultaneously. This combining of new technology and handicraft serves as a reservoir for a remarkable diversity and originality in the development of new technology and design, and constitutes an important trend in modern industrial textiles. The aim of this study is to investigate the developmental background of Japanese textile industry that championed this trend to make the Japanese development unique in modern textile industries and to consider the concept of modern textiles as well as the structural innovation as represented by this new trend, thus contributing to the development of creative textiles for the present and the future. The findings of this study can be summarized as follows. The combining of new technology and traditional handicraft: 1) was made possible by Japanese consciousness that values traditional culture and by early recognition of advanced textile industry, which awarded new meaning and value to the traditional handicraft leading to an expanded social role for textiles. 2) helped construct a modern concept of textiles by pursuing textile media that are state-of-the-art, aesthetic, and highly sensitive to satisfy the requirements of modern industrial textile such as high quality, high performance, and high sensitivity. 3) enabled new design ideas and creation of new styles by implementing structural innovation in industrial textiles that involved diversification of expression, diversity in materials, and emphasis on texture. In short, by combining new technology and traditional handicraft, Japan came up with a new sense of aesthetics that is highly original and high level and with which the rest of the world can easily sympathize, thereby presenting one of the most important guiding principles for future textiles.

We have approached this study on the basis of population and family changes. We have selected two suburban and two general rural areas for this research. The suburban rural areas are located next to Chungju City, which is the biggest city in Chungbuk Province, and the residents are able to commute to Chungju. The general rural areas are located in Boeun Gun, which is a typical agricultural county in Chungbuk Province. We have conducted two round surveys at the research areas: 1995-1996 for the first round and 1999-2000 for the second round surveys. Since the surveys were completed ones interviewed by enumerators, we have used the survey data directly for the analysis by year and region. The population structure by age and sex in general rural areas is shaped as a reverse triangle, which is becoming more serious because of the continuing emigration of young generation. Most of the young generation moves to the urban areas and their old parents only are left in their hometown, rural areas. When the parents become old and die, the number of households in the areas decreases rapidly. If there are no more new family formations, therefore, the rural society itself would cease to exist in near future. However, the situation of suburban rural areas was a different case. Although the rural young generation has moved to urban areas, other young age groups have moved into the areas with their small enterprises and for the low living costs. The original residents become older and the young age groups are replaced with the new immigrants continuously. Therefore, the traditional agricultural society will be replaced with a non-agricultural society, which will have more characteristics of urban areas.

Recently, with the rapid growth of the O2O market, Fintech combining the finance and ICT technology is drawing attention as innovation to lead "O2O of finance", along with Fintech-based payment, authentication, security technology and related services. For new technology industries such as Fintech, technical sources, related systems and regulations are important but previous studies on Fintech lack in-depth research about systems and technological trends of the domestic Fintech industry. Therefore, this study aims to analyze domestic Fintech trends and find the insights for the direction of technology and systems of the future domestic Fintech industry by comparing Kakao Pay and Samsung Pay, the two domestic representative mobile payment services. By conducting a complete enumeration survey about the tweets mentioning Fintech until June 2016, this study visualized topics extraction, sensitivity analysis and keyword analyses. According to the analysis results, it was found that various topics have been created in the technologies and systems between 2014 and 2016 and different keywords and reactions were extracted between topics of Samsung Pay based on "devices" such as Galaxy and Kakao Pay based on "service" such as KakaoTalk. This study contributes to analyzing the unstructured data of social media by period by using social media mining and quantifying the expectations and reactions of consumers to services through the sentiment analysis. It is expected to be the foundation of Fintech industry development by presenting a strategic direction to Fintech related practitioners.
