음악의 속도에 따라 운동하는 방법을 제공하는 기존의 연구에서는 사용자가 직접 재생되는 음악을 변경해주어야 하는 방법이 사용되었다. 그러나 사용자가 직접 음악 재생을 조절하는 방법에서 빠른 음악을 재생하고자 했을 때 사용자가 음악을 검색하다가 운동 흐름이 끊어지는 문제점이 있다. 본 논문에서는 웨어러블 스마트 신발의 사용자로부터 걸음 수를 측정하는 모듈을 아두이노 기반으로 설계하고 안드로이드 기반의 스마트폰으로 데이터를 전송하여 정확한 걸음 수를 측정 할 수 있도록 구현하였다. 그리고 GPS를 활용함으로써 걸음속도 및 이동 거리를 측정하여 보다 정확한 운동량을 측정할 수 있도록 하였다. 또한 이동거리에 따른 칼로리 소모량과 걸음 수에 따른 칼로리 소모량의 평균값을 측정해 기존의 제품보다 정확한 칼로리 소모를 측정하며, 걸음속도에 따라 음악 장르 변경 알고리즘을 적용시켜 사용자에게 운동 동기를 부여하고 동시에 운동효과를 증대시킬 수 있게 하였다. In the existing studies providing a method which do exercise according to music speed, the method was used which a user changes playing musics. However, if the method which a user changes directly playing musics is used, flow of exercise can be discontinued during searching musics when anyone want to play a fast music. In this paper, we designed the module which measures the number of steps from a user of wearable smart shoes based on the Arduino, and implemented the module so that the number of steps can be measured correctly by sending data to smart phone based on Android. And it is possible to measure moving distance and pace speed by utilizing a GPS in order to get the more accurate momentum. Also, we can measure more accurate calorie consumption than existing products by measuring the mean value of the calorie consumption for moving distance and the calorie consumption for the number of steps, give motivation of exercise by applying an algorithm of changing music genre according to pace speed, and increase the exercise effect at the same time.

This experiment was carried out to elucidate the biological activity and absorption characteristics of flavonoids in Rhizobium and Bradyrhizobium and to obtain basic information on host specific nodulation by flavonoids in rhizobium-legume symbiosis. The purpose of the present study was to explore the biological activity and the flavonoid absorption indicates that host-specificity is induced by flavonoids in symbiotic nitrogen fixation. Biological activity increased by daidzein and genistein treatment on B. japonicum KCTC 1539 whereas decreased by luteolin treatment but increased by luteolin treatment on R. meliloti whereas decreased by daidzein and genistein treatment. Daidzein and genistein are absorbed by B. japonicum, KCTC 1539 at higher rate than other flavonoids. Especially, luteolin was absorbed at a least rate. Luteolin are absorbed by R. meliloti KCTC 2353 at higher rate than other flavonoids. Especially, daidzein and genistein was absorbed at a least rate.

The purpose of this study is to construct the database and to analyze the space and to suggest the possibility of application for architectural planning and design through the approach analysis for educational facilities with the use of the GIS. The properties of the space is to be expressed by optimized path from the analysis of the user and the traffic situation. Analyzed with other site analysis factors(situation, view, noise, configuration of the earth, etc.), the total site analysis is to be made and it is also to be a decision making support system.

This study purpose is extract on the architectural principles and architectural planning direction for Integrated Secondary School. The integrated secondary school has an expectation of the total education environment in which has some problem as regional, teaching, treatment, establishment equipment part because of the based relative establishments are abolished. The expectations are the education effective rising, the reduce of the responsibility of the teacher, a smooth teacher placing and saving the educating estimate. As the new education course propulsion is raising the school and students discretion and expanding the way of educating, being close to the course of studies, the integrated operation is earnestly needed and such as these versatile background the small school will keep on getting integrated. Investigate about the senses of the manager and teachers, so after these reserch I've concluded these things below about the integrated secondary school.

비사실적 렌더링 기법(NPR, Non Photorealistic Rendering)에 대한 관심이 증가하면서 여러 컴퓨터 그래픽스 연구자들에 의해서 펜화, 수채화 , 인상파 기법 등 예술적 기법들을 표현하기 위한 연구가 진행되어 오고 있다. 비사실적 렌더링 기법에서 가장 초점을 두고있는 것은 사람이 직접 그리거나 조작 한 듯한 표현을 만들어 낼 수 있으냐 하는 것이다. 본 논문은 교육이나 예술적인 표현을 위해 사용되고 있는 종이를 찢어 붙여 표현하는 모자이크 작품을 자도으로 생성해 주는 기법을 제시하였다. 이를 위해 종 이를 칼이나 가위같은 도구에 의해 잘려진 것이 아닌 자연스럽게 찢어진 종이 표현 기술, 종이의 질감 표 현 기술, 붙여지는 종이의 형태를 결정하기 위한 다각형 생성기법등을 제시한다. Recently as it is growing concern about NPR(Non-Photorealistic Rendering), Several computer graphics researchers are studying to simulate conventional artistic expressions such as pen-and-ink illustrations, watercolor and impressionism technique. In the NPR it is important thing that someone can produce a representation looked like work drawn or manipulated people directly. In this paper we propose that the technique could make the mosaic work automatically, tore and tagged a paper by hands used to educational and artistical representation, we suggest various methods to express a shape and texture of paper tore by hands without using cutters or scissors.

정치적 부패가 공적개발원조(ODA) 및 외국인직접투자(FDI)의 유입에 미치는 영향
서상현(SEO, SANG HYUN) 한국아프리카학회 2016 한국아프리카학회지 Vol.49 No.-
사하라이남 아프리카 지역이 아직 다른 지역에 비해 가난과 빈곤이 많은 요인들은 여러 가지가 있을 수 있으나 그 중 가장 심각한 문제 중 하나가 정치적 부패의 문제를 들 수 있다. 세계투명성기구의 2015년 보고서에 의하면 아프리카 국가들의 2015년 부패인식지수(CPI)는 세계의 다른 지역에 비하여 현저히 낮은 수준이다. 특히 사하라이남 아프리카 국가들의 부패인식지수는 32.7로 세계평균 42.6에 비하여 현저히 낮게 나타났다. 이에 비하여 중동 및 북아프리카 국가들은 이보다 조금 높은 38.6로 나타났으며, 아시아 태평양국가들은 42.5, 미주대륙 국가들은 40.5로 평가되었다. Mauro(1995)에 따르면, 정치적 부패는 투자를 저해하고 경제 성장을 저해할 것으로 지적되고 있으며, 또한 아프리카에 대한 민간 투자가 다른 지역에 비해 낮은 것도 이 같은 정치적 부패가 아프리카 지역의 경제 하락의 큰 요인 중 하나임을 시사한다. 아프리카 역시 정치권의 부정부패 등으로 인해 FDI 유입이 제약되고 이로 인해 인프라 확충 및 개선도 제약받고 있다. 본 연구는 위의 내용들을 바탕으로 아프리카에서의 만연한 정치부패가 아프리카 경제 성장의 원동력이 되는 ODA와 FDI 유입에 어떤 영향을 미치고 있는지를 분석한다. There are many poverty factors in sub-Saharan Africa, but one of the most serious problems is political corruption. In terms of the World Transparency Organization(2015), African countries" Corruption Perceptions Index(CPI) in 2015 is significantly lower than in other parts of the world. In particular, the CPI of sub-Saharan African countries have 32.7, which is significantly lower than the world average of 42.6, with 42.5 for the Asia-Pacific countries and 40.5 for the Americas. According to Mauro (1995), political corruption is to hinder investment and economic growth. In addition, private investment in Africa is lower than in other regions, suggesting that such political corruption is a major factor in the economic downturn in Africa. FDI inflows are also restricted due to political corruption, and infrastructure expansion and improvement are limited. In this research, based on the above contents, I analyzes the effects of prevailing political corruption in Africa on the influx of FDI and ODA, which is the driving force of African economic growth.

Is South Africa leaving the era of Nelson Mandela? After the country’s 19 years of de facto single party rule under the African National Congress (ANC), the party of Mandela and of liberation has experienced serious internal divisions over leadership personality, alleged corruption, and ideological conflict. Such divisions led prominent ANC vanguard Mosiua Letoka to officially sever his ties with the ANC and found the Congress of the People (COPE). Letoka, who was the former defense minister and close ally of recently-ousted president Thabo Mbeki, signaled a acute change in atmosphere of South African politics. What is certain, however, is that the challenge presented by COPE will be a catalyst for internal change within the ANC. Most importantly, the emergence of COPE has the potential to highlight the intensity of ethnic and tribal division within the ANC and the South African political establishment. This has always been more prominent in the opposition parties, such as the Democratic Party (DA) or Inkatha Freedom Party (IFP). The DA has been long criticized for inheriting the crux of the Democratic Party during apartheid, establishing itself as a “pro-white” party even till today. IFP has always been firmly rooted in its KwaZuluNatal turf, rarely influencing the political arena beyond its Zulu base. Yet, the ANC has been able to avoid this slippage into the ethno-nationalistic politics through rotation of top positions and more subtle procedural conventions. Lethoka, however, has brought to light that this mechanism of forestalling ethnic mobilization has failed, and the ANC must look towards reform.
