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.

서상현,박영섭,윤경현,Seo, Sang-Hyun,Park, Young-Sup,Yoon, Kyung-Hyun 한국정보과학회 2002 정보과학회논문지 : 시스템 및 이론 Vol.29 No.1

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.

Based on the supply status statistics of new renewable energy according to public obligation system, current status of overall application centered on solar heat, solar ray, and geothermal heat as energy sources that can be applied to buildings may be analyzed as follows. (1) After the public obligation system, the investment costs on the total construction costsby years were between 5.21% and 7.12%: they were 7.12% in 2004, where the system was initially implemented; and they were gradually declined from 2005 to 2011, 5.76% in average.The ratio of equipment investment per energy sources in the total construction costs was 5.9%, which was slightly more than the obliged ratio.Theorder of investment costs per energy source was solar ray, geothermal heat, and solar heat. (2)Among the1,433 sitesin the plan of new renewable energy installation based on the public obligation system,“forcultural & socialuse” was most in target institution, and facilities for education & research was most in use classification, followed by public working, culture & rally, and sports. The number of facilities applied according to the case for planning installation per use classification ofthe target institution was between 1.1 and 1.5,or1.4 in average of energy source. Conclusively, the authors of this study investigated overall current status of new renewable energy supply from thean alysis of statistic data, and it may be needed of further supplementation of various examinations by visiting investigation and interviews with practitioners based on classification of use of target institutions.

아파르트헤이트 철폐이후 남아공의 신자유주의정책과 노동운동

The transition to democracy led by the African National Congress (ANC) was trumped by the transition to neoliberalism. The new ruling elite and the beneficiaries of the old apartheid regime had already made common cause after the ANC came to power in 1994. Now they were cementing their alliance with the corporate raiders in the advanced capitalist world. Also central to the transition is the impact of the ANC's macroeconomic strategy on the composition of the South African working class. According to the 1996 Census, the poorest 40 percent of the population got less than 3 percent of the national income, while the richest 10 percent enjoyed over 50 percent. The situation has worsened over the past decade for the poorest 40 percent of African households. Twenty percent of urban households have no electricity and a quarter have no running water, while 80 percent of rural households have neither. As part of the process of "normalization," the government's Growth, Employment and Redistribution (GEAR) program aims toward "a fundamental shift away from the 'statist' service delivery models of the past where the state subsidized and delivered municipal services (albeit in a racially-biased manner), towards a more 'neo-liberal' service delivery model where the private sector (and private sector principles) dominate. This, in tum, has caused increasing cost-recovery mechanisms such as disconnections of water and electricity to occupy the attention and energy of the local state, as opposed to delivery in the first place. Between 1999 and 2000, for example, some 75,400 water cut-offs occurred in the Greater Cape Town area. In Soweto after the 1999 general election, some 20,000 houses had their electricity supplies disconnected every month. What distinguishes these community movements from political parties, pressure groups, NGOs, and the trade unions is mass mobilization as the prime source of social sanction. The rise of community movements has seen the emergence of the family as a fighting unit, unlike union membership, which is based on the individual worker. In fact, many of those involved in community movements accept the conditions of the sweatshops and low wages without much of a fight. The political had to be controlled by the ANC or its allies in the Tripartite Alliance-the Congress of South African Trade Unions (COSATU), and the South African Communist Party (SACP). The rightward shift of the ANC, however, has from time to time been challenged by the leading trade union federation, COSATU, working within the rubric of the Alliance. However, the latter's attempts to advance its interests is so highly ritualized, domesticated within the ANC Alliance and otherwise institutionalized, that COSATU shows little inclination to act outside and against the major policy decisions of the ANC. Crucially, COSATU sees its alliance with the ANC as the bulwark against job losses by tempering the worst excesses of neoliberalism. Conflict is channeled through tripartite (business, labor, and state) corporatist structures. The recent South African Municipal Workers Union (SAMWU) strike does, however, indicate a fertile ground for a linkup between community movements and the organized working class. Many SAMWU shop stewards, especially in the Western Cape, are integrally involved in community movements. The privatization of services means SAMWU workers face the spectre of both job losses and increases in charges for basic services, merging in their immediate identities as municipal employees and township residents. It is also significant that the strike took place against the local state, which also is the target of the community movements. The strike brought to public attention the growing gap between municipal managers and workers.

ATM 교환시스템에서 사용되는 넉아웃 스위치의 포트간 경합 처리의 불균등성 개선

서상현(Sang-Hyun Seo),김재홍(Jae-Hong Kim),박상규(Sang-Kyu Park),이상조(Sang-Jo Lee) 한국정보과학회 1996 한국정보과학회 학술발표논문집 Vol.23 No.2B

고속 대용량의 ATM 교환시스템으로서 교차형 방식이나 공통메모리형 방식은 내부 블록킹의 적절한 처리, 다중화 및 역다중화기의 처리능력에 많은 문제가 있다. N² 경로형의 넉아웃 스위치는 입력부의 경합이 없고 자체 경로 배정이 가능하며 출력 경합이 경합접속기라는 비교적 간단한 구조의 하드웨어에 의해 병렬로 수행된다. 따라서, 처리율이 높고, 지연 시간이 낮으며, 교환 과정이 매우 간단하다는 측면에서 고속 대용량의 ATM 교환시스템에 보다 적합하다. 그러나, 기존의 넉아웃 스위치는 근본적으로 입력 포트 간에 경합 처리의 불균등성이 존재한다. 이는 각 포트별 전송량 및 셀 손실율에 영향을 주게 되며, 넉아웃 스위치가 대용량이 될수록 입력간에 불균등성이 심화된다. 이것은 경합접속기를 구성하는 단위 스위치 소자인 경함스위치의 구조적인 불균형성에서 비롯된다. 본 논문에서는 경합스위치의 경합 방식을 최근 사용된 포트에 우선순위를 주어 각 입력 포트 별로 통계적 균등 우선 순위 특성을 갖도록 하는 경합스위치를 설계하였다. 이로 인한 경합접속기의 회로 복잡도의 증가는 무시할 수준이다. 제안된 경합스위치를 사용하여 입력 간에 균등한 우선 순위 분포 및 셀 손실율을 보이는 넉아웃 스위치를 구성하고, 그 성능을 시뮬레이션을 통해 보인다.
