The government is mapping out R&D innovation measures aimed at improving the qualitative level of the performance of national R&D projects that are supported by grants or public funds. This paper proposes ways of making improvements in technology planning, project assessment, performance management, and results evaluation in order to boost the efficiency of the country's promotion of ICT R&D projects, as well as to upgrade the processes involved with its technological innovation system at each of the commercialization stages of its R&D projects. According to our experts' in-depth survey and interview, it has been found that technology planning is the most important phase in the full cycle-based technological innovation system and that the promotion of a combination of top-down and bottom-up approaches is the most reasonable. This paper also suggests it is necessary to secure a process for exploring technological opportunities as the preparatory phase for technology planning, and that it is desirable to reflect the technology demand map associated with the technology road map. Currently, R&D projects are divided into policy designation, designation contest, and free contest. To minimize the inefficiency associated with indiscriminate competition, this paper proposes the introduction of a general contest system in order to change the project assessment system into one based on the results of the competition in each category(e.g. firms, universities, research institutions, etc.).

There are approximately 250,000 organic livestock farming in the world. The total retail value of organic food sales in the world is $ 27 billion. The organic livestock products such as milk, lamb and beef are marketed mostly in Europe and the USA. The market share of organic food is about 2% in total food marketing value of worldwide and of the organic food marketing value, organic livestock products portioned 17% in the USA. The organic livestock products are primarily marketed at Supermarket(Europe), Health and Natural Food store(USA). Concerning international trade, it is very little. But it is increasing among the developed counties of Europe. In the future, the production of organic livestock products will be rapidly increased in South America, Middle East and Oceania, but the growth rate will be limited due to its expensive price, lack of marketing-infra and different regulation system. Most of developed countries drive organic farming policy strongly as the strategic means of rural development, diversifying agriculture system and environmental improvement.

Purpose: The purpose of this study was to examine the effects of performing a dual task on gait velocity, temporospatial variables, and symmetry in subjects with subacute stroke. Methods: The study included 14 independent community ambulators with gait velocity of 0.8m/s. The Korean mini-mental state examination, the Berg balance scale, the Trunk impairment scale, and the Fugl-Meyer assessment scale were used to recruit homogeneous subjects. Subjects performed a single task (10m ambulation at a comfortable speed) and a dual task (10m ambulation at a comfortable speed while carrying a water-filled glass). Gait variables were examined with the OptoGait system. Results: The findings of this study were as follows: 1) Gait velocity decreased significantly in the dual-task condition as compared to the single task condition. 2) There were no significant differences between the paretic and non-paretic stances. 3) Paretic swing decreased significantly in the dual-task condition as compared to the single task condition. 4) The non-paretic, double-limb support phase increased significantly in the dual-task condition as compared to the single- task condition. 5) There was no significant difference in temporal symmetry. 6) Non-paretic step length decreased significantly in the dual-task condition as compared to the single-task condition. 7) There was no significant difference in spatial symmetry. Conclusion: Performing dual tasks decreases gait velocity, paretic swing phase, and non-paretic step length, while it increases non-paretic double limb support. In addition, although there is no difference in temporospatial symmetry, there is high inter-subject variability in temporospatial symmetry. Thus, dual tasks should be selected in accordance with the functional level of the hemiplegic patient, and inter-subject variability of the individual should be considered when dual tasks are considered for gait-training of hemiplegic patients.

PURPOSE: This study compared the effects of dual motor task training and simple task training on the balance of subacute stroke patients. METHODS: A total of 23 subacute stroke patients participated in the study. The subjects were allocated randomly to two groups: an experimental group and a control group. Both groups received conventional treatment for 50 minutes, 5 times per week for 6 weeks. In addition, the experimental group stacked blocks, moved catch cups, and moved rings while standing and gait. To evaluate the effects of the exercises, subjects were evaluated by using the balance system and the timed get up and go test(TUG) for balance measurement. The data was analyzed using a paired t-test and independent t-test to determine the statistical significance. RESULTS: The experimental group showed a significant decrease on the medial-lateral and anterior-posterior stability index compared to the control group (p<.05) for the simple task and a significant decrease on the medial-lateral and anterior-posterior stability index compared to the control group for the dual task. In addition, the experimental group showed a significant increase in TUG time compared to the control group (p<.05). CONCLUSION: These results support the perceived benefits of dual motor task training to augment the balance of subacute stroke patients. Therefore, dual motor task training is recommended for subacute stroke patients.

Objectives: The purpose of this study was to examine the performance and electrophysiological characteristics of drug-naive children with attention-deficit/hyperactivity disorder(ADHD) during the Go/NoGo task. Methods: Twenty-three boys with ADHD and 18 age-matched normal boys were recruited at a child psychiatric outpatient clinic in Seoul. All subjects were assessed by the Kiddie Schedules for Affective Disorders and Schizophrenia Present and Lifetime version. The investigator also assessed all subjects using the ADHD Rating Scale-IV(ADHDRS). Event-related potentials were recorded from 8 scalp electrodes during the visual Go/NoGo task. Results: Children with ADHD showed a larger mean of standard deviation of response time during the Go/NoGo task than normal children. The temporal N200 and P300 amplitudes were larger in children with ADHD relative to controls. The parietal N200 and P300 latencies were more prolonged in children with ADHD compared to normal controls. Conclusion: These results suggest that psychotropic-naive children with ADHD may have more variable performance ability, more difficulty in discriminating visual stimuli, and slower information processing speed than their normal age-matched counterparts.

The purpose of this study is to analyze outpatients of glaucoma aged 20 or older about their five-year use of ophthalmology and investigate trend of prevalence in glaucoma patients. The Korea Health Panel (KHP) data from 2008 to 2012 were analyzed using frequency and chi-square tests. The outpatients of glaucoma have increased significantly from 0.43% in 2008 to 0.47% in 2009, 0.49% in 2010, 0.61% in 2011, and 0.75% in 2012 (p<0.001). The outpatients of glaucoma are in the 20's to 70's, and higher utility rate is shown in those who are older (p<0.001), and the rate of use tends to increase each year in all the age groups (p<0.001). The medical care utilization attributed to glaucoma in Korea tends to increase lately; therefore, it is a crucial task to realize early detection and management according to the characteristics of different age groups.

인류가 산업발전 등으로 인해 석유등 화석연료를 사용함에 따라 대기오염은 날로 악화되어 1952년 런던스모그 같은 참사를 맞이하였고 이에 각국은 이러한 대기 오염물질을 저감하기 위하여 노력한 결과 대기 오염물질은 낮아지고 있으나 이에 반해 이산화탄소 배출량 증가에 따른 지구 온난화 현상과 오존층 파괴는 지역적인 환경문제에서 번세계적인 환경문제로 확산 전개되고 있다. 특히 산업혁명후 화석연료의 급격한 사용증가로 인한 이산화탄소 배출량 증가는 지구를 온나화시키고 수십년 후에는 환경에 심각한 영향을 주게 되는 것은 의심할 여지가 없는 것으로 이는 지구환경문제 중에서 금회 최대의 과제로 대두되게 되었다. 이에 따라 1985년 UNEP 관리 이사회를 필두로 "지구환경보전에 관한 동경회의", "대기오염 및 기후변동에 관한 노드윅 회의", "백악관회의", "휴스톤 Summit" 등에서 이 문제가 거론되기 시작하여 '90. 8월에는 스웨덴에서 온난화에 대한 과학적 인식과 대책의 메카니즘을 정하기 위한 IPCC 4차 회의가 각국 대표들이 참석한 가운데 정치, 경제, 과학의 문제로 등장하여 우리생활의 근본을 좌우할 다각적인 논의가 진행된 바 있다. 또한 미국, 영국, 일본 등 선진국들의 정상이 모이는 G7 회담 등에서 논의되고 있는 것들 중 정치적인 문제를 제외하고는 환경문제를 가장 많이 다룬다는 외신보도를 우리는 여러번 접한바 있다. 현재 국제적 환경문제로 가장 관심이 집중되고 있는 문제 중 몇가지를 소개하면 우선 <몬트리올의 정서에 의한 오존층 보호>를 들 수 있겠고, 최근 국제 협약 제정을 추진하고 있는 "지구온난화 방지에 관한 기후협약" 그리고 유해폐기물의 국제교역에 관한 "바젤협약"과 함께 새로이 제기된 "생물학적 다양성 협약"등이 거론되고 있으며, 이에 덧붙여 미국의 "자동차배출가스 규제"도 우리나라 산업에 큰 영향을 미칠 것으로 판단된다. 본 논문은 이중 대기와 관련된 오존층 보호와 지구온난화 대책에 대한 국제회의 등에서 현재까지 논의되었거나 토의될 내용에 대하여 기술하고 특히 금년부터 집중적으로 국제협상이 진행될 지구온난화 문제에 대한 최근의 국제동향 우리나라의 입장을 기술하고자 한다.

The recent increase of wages is considered to be the result of lawsuits on ordinary wage expansion and the reduction of working hours. This may enlarge the wage gap between enterprise and small business, and thus worsen the insufficient supply of workforce to small businesses. Therefore, it is necessary to provide strategies to control the increase of wages in order to resolve the difficulty in the industrial workforce supply and to enforce the industrial competitiveness.
