The digital tachograph is a device that automatically records speed and distance of a vehicle, together with the driver's activity and vehicle status at an accident. It records vehicle speed, break status, acceleration, engine RPM, longitude and latitude of GPS, accumulated distance, and so on. European Commission regulation made digital tachographs mandatory for all trucks from 2005. Republic of Korea made digital tachographs mandatory for all new business vehicles from 2011 and is widening the range of vehicles that must install digital tachographs year by year. This device is used to analyze driver's daily driving information and car accidents. Under a car accident that makes the device reliability unpredictable, it is very important to store driving information with maximum reliability for its original mission. We designed and implemented a practical digital tachograph. This paper presents a storage scheme that consists of a first storage device with small capacity at a high reliability and a second storage device with large capacity at a low cost in order to reliably records data with a hardware at a low cost. The first storage device records data in a SLC NAND flash memory in a log-structured style. We present a reverse partial scan that overcomes the slow scan time of log-structured storages at the boot stage. The scheme reduced the scan time of the first storage device by 1/50. In addition, our design includes a scheme that fast stores data at a moment of accident by 1/20 of data transfer time of a normal method.

2009년은 그야말로 새옹지마(塞翁之馬 : 인생에 있어서 길흉화복은 항상 바뀌어 미리 헤아릴 수 없다)와 같은 한 해로 기억에 오래 남을 듯 하다. 2008년 말에 2009년 양돈산업을 전망할 때 미국발 금융위기에도 불구하고 국내산 돈육 공급량 부족과 환율상승 및 급변으로 인한 돈육 수입량 부족, 그리고 수급 불균형으로 대부분의 전문가들이 역대 최고의 돈가를 예상했고, 실제로 3월에 지육가격이 5,000원/지육kg(전국 비육돈 평균시세)을 상회하면서 성수기에 돈가가 6,000원/지육 kg에 육박할 것이라 기대했었다. 그러나 4월 미국에서 발생한 신종인플루엔자가 초기에 돼지에서 유래된 인플루엔자라고 보도되면서 돈육소비량이 급감하였고 이로 인해 성수기에 돈가가 오히려 하락하는 기현상을 보였다. 다행히 신종플루가 돼지와 무관하다는 사실이 밝혀지면서 소비가 회복되었고 돈가 또한 회복되어 올해는 역대 최고의 돈가가 형성될 것으로 예상되고, 여기에 국제곡물시세가 안정되면서 사료가격도 여러 차례 인하되어 양돈 농장의 수익성은 상당부분 향상될 것으로 판단된다. 하지만 신종플루 사망자가 증가하면서 지금도 여전히 돈육소비가 위축되어 있어 막연히 호황을 기대하기 쉽지 않은 실정이다. 돈가의 급등과 급락, 외부요인에 의한 경제환경의 변화로 인한 환율의 변동 및 소비량의 변화는 2009년 양돈산업에 대한 불안감을 증폭시켜 높은 돈가와 수익성에도 불구하고 전체 산업의 규모가 커지지는 못했다. 여기에 국산 돈육에 대한 소비자들의 무한 신뢰로 인해, 2008년 12월 돈육 원산지 표시제 확대 실시로 국내산 돈육 수요가 증가 하여 여전히 75% 가량의 국산 돈육 자급율을 유지함에도 불구하고 아직까지 맛의 차별화 및 도축, 유통의 안전성에 대한 확고한 신뢰 구축을 위한 브랜드 돈육 유통의 확대가 소비자의 기대치만큼 자리 잡지 못하고 있는 실정이다. 또한 친환경적인 양돈산업 육성 및 분뇨 처리 관련하여도 뚜렷한 해답을 찾지 못하고 있어, 양돈 농가의 입장에서는 규모의 확장 및 신규 진입이 극도로 제한되어 있고 일부 지역에서는 사업의 존폐를 결정하는 주요 원인이 되고 있다. 그간 대한민국 양돈 산업의 경쟁력에 발목을 잡고 있던 낮은 생산성 문제와 소모성 질병에 의한 높은 폐사율 문제 또한 아직도 여전히 해결되지 못한 과제이다. <그림 1> 국가별 양돈 농장 생산성 현황에서 보는 바 와 우리나라 양돈 농장의 생산성은 여전히 PSY(모돈당 연간 이유자돈 두수)가 18두에 못 미치고 있어 국제 경쟁력을 논하기 자제 가 부끄러운 실정이다. 여러 가지 내 외부적인 어려운 환경에도 불구하고 올 2009년은 양돈농가들이 최고의 수익성을 기록한 한 해가 될 것이라는 사실에는 이의가 별로 없을 듯하다. 2년 여간의 고돈가로 인해 대한민국 양돈산업은 새로운 도약을 위한 밑천이 마련된 셈이라고 할 수 있다. 본고에서는 2009년 양돈산업 현황을 돌아보고 다가올 미래를 준비한다는 의미에서 우리나라 양돈산업이 집중해야 할 분야를 짚어보고자 한다.

최근 홍수파 또는 댐 및 보 등의 하천구조물과, 본류와 지류의 합류로 인해 발생하는 배수영향 등으로 하천에 고리형 수위-유량관계가 나타나 수위-유량관계식의 신뢰도가 저하된다고 판단되는 대하천 본류와 합류부 인근 지류에서 초음파유속계 측정결과를 지표로 활용하는 자동유량장치가 현재 58개소에 도입되어 운용되고 있다. 그러나, 최근 4대강 사업으로 다기능보 설치 등 하천의 수리적 특성이 변동하였고, 지류에서 주로 운용되는 수위-유량관계 기반 유량관측소에 본류-지류합류로 인한 배수영향으로 고리형 수위-유량관계가 형성될 경우, 지류 수위관측소를 자동유량관측소로 대체할 필요성이 제기되고 있다. 또한, 기존 자동유량관측소의 경우 홍수량이 기준이하로 나타날 경우 수위-유량 관계식으로 대체하는 경우도 있는데 적용기준이 명확하지 않다. 본 연구에서는 신규 자동유량장치 설치, 기존 수위관측소의 자동유량관측소대체, 자동유량관측소에서 수위-유량관계곡선의 활용 기준 마련 등을 명확하게 판단하기 위해 고리형 수위-유량관계 패턴을 분석하고 배수영향구간을 산정하여 제시하고 지류 수위관측소의 존속여부, 유량자료의 적절성을 판단할 수 있는 방법론을 제시 하고자한다. 이를 위해, 다기능보 설치 및 지류-본류로 인한 지류하천의 배수영향과 홍수파에 의한 고리형 수위-유량관계의 양상을 다양한 수문사상에 대해 분석하였다. 분석방법으로는 대상유역을 선정하고, 대상유역에 대한 부정류 모형을 구축하기 위해 HEC-RAS 모형을 사용하고, 대상유역에 대한 HEC-RAS 지형자료와 유량입력자료를 구축한다. HEC-RAS 부정류 모형 구축 후 다양한 본류와 지류의 유량을 가정하여 고리형 수위-유량 발생 패턴을 분석한다. 지류-본류 합류 영향의 경우, 본류영향의 유무를 고려하여 상승된 수위의 비율로부터 일정 유의수준을 두어 배수영향구간을 산정한다. 다기능보의 영향은 다기능보 설치 전후를 가정하여 영향을 분석한다. 본 연구에서는 시범구역으로 하류에 창녕함안보가 위치한 낙동강과 합류하는 남강과 하류에 달성보가 위치한 낙동강과 합류하는 금호강을 대상하천으로 하여 위 분석방법을 적용하였다. 분석결과 남강의 경우 지류 유량이 작은 경우에도 본류 유량이 상대적으로 큰 경우 배수영향에 의한 고리형이 나타났고, 다기능보에 의한 배수영향은 매우 적은 것으로 나타났다. 또한, 지류의 유량이 큰 경우 홍수파에 의한 고리형 관계도 발생함을 알 수 있었다. 금호강의 경우 또한 마찬가지로 본류의 유량에 의해 발생하는 고려형 관계가 지배적임을 알 수 있었다. 따라서 이러한 결과를 바탕으로 95%의 유의 수준을 기반으로 고리형 발생 여부를 확일할 수 있는 모노그래프를 남강, 금호강에 대해 작성하여 수위-유량관계 기반 유량 산정의 적절성을 판단하는 기준으로 제안하였다.

Recently, housing prices in metropolitan areas is also increasing in the UK and Australia. Their governments are trying to solve this problem by the housing development in the quarry sites near cities. The cases reviewed in this study, Erith Hill Quarry (The Quarry), Plymstock Quarry, Lilydale Quarry (Kinley), and Bombo Quarry are the mixed-used development cases in the closed quarry sites through the urban planning system. In the UK, the local government uses the urban planning scheme such as the planning permit system, section 106. The local government permits the quarry site development on the condition that it provides necessary public facilities, such as schools and affordable housing for the local community. In Australia, local governments use up-zoning permission rights to convert land uses in quarries from industrial to mixed-use. Development plans have to include urban infrastructure and open space in addition to affordable housings. In the case of Australia, establishing a development plan in advance and filling the quarry pit with overburden through a phased development is expected to have the effect of reducing the project cost. Both countries think that developing brownfields, such as quarry sites, is a more sustainable and eco-friendly development from the perspective of future generations than developing new green fields. Such a perspective of the UK and Australia will be able to give policy implications for our slightly rigid urban development system.

The purpose of this research was to examine the experiences of three types of family-friendly workplace professionals (professionals here after) including consultants, certification auditors, and professional instructors, and to provide suggestions for the improvement of training programs aimed at such professionals. Ten professionals participated in focus group interviews. Two themes were identified: the competencies of the professionals and ways to improve the training system and the curriculums of training programs. Competencies are dependent on job type. Therefore, different training programs should be provided to the three types of professionals. To make training programs more comprehensive, most participants agreed that training program curriculums for the three types of professionals should link together. Participants also suggested increasing training time and differentiating training programs between new and experienced specialists. In terms of improving the training system, professional networking and the creation of a database for family-friendly programs were discussed. The findings suggest that training programs need to be restructured in line with the competencies required by the professionals and professionals' needs.

This paper used big data and artificial intelligence technology to predict the rapidly increasing internet traffic. There have been various studies on traffic prediction in the past, but they have not been able to reflect the increasing factors that induce huge Internet traffic such as smartphones and streaming in recent years. In addition, event-like factors such as the release of large-capacity popular games or the provision of new contents by OTT (Over the Top) operators are more difficult to predict in advance. Due to these characteristics, it was impossible for an ISP (Internet Service Provider) to reflect real-time service quality management or traffic forecasts in the network business environment with the existing method. Therefore, in this study, in order to solve this problem, an Internet traffic collection system was constructed that searches, discriminates and collects traffic data in real time, separate from the existing NMS. Through this, the flexibility and elasticity to automatically register the data of the collection target are secured, and real-time network quality monitoring is possible. In addition, a large amount of traffic data collected from the system was analyzed by machine learning (AI) to predict future traffic of OTT operators. Through this, more scientific and systematic prediction was possible, and in addition, it was possible to optimize the interworking between ISP operators and to secure the quality of large-scale OTT services.

In order to survive the on-going natural resource war, Korea needs various efforts such as enhancing self-exploitation ratio, increasing the supply of new-reuse energy, strengthening cooperation with resource rich countries. Central Asian countries are geometrically far away from Korea. However, Korea should try to develop political, economic and ethnic relationship with those countries into much higher dimension to secure various natural resources. Major countries including U.S., EU. Japan and China are approaching Central Asian countries with long term perspective. Improving country-image through enlargement of ODA is the first concern of those countries. Korea should try to follow their practices. Government should try to improve Korea's image in the first place and lead economic cooperation with very detailed supportive measures to induce Korean firms' investment into the Central Asian countries. In the due process, a lot of information about those countries' political climate, social situation, ethnical composition, major religions, educational system, current state and structure of economies and industries, etc should be made available to Korean firms.
