Objectives : The purpose of this study is to investigate the latest trends of korean Medicine treatments on traffic accident for recent 5 years. Methods : We investigated the studies on korean Medicine treatments for traffic accident via searching 6 Korean web databases. As a result, 65 research papers were found to be analyzed according to their published year, the titles of journals, the types of study, the number of cases, the sites of injury, the types of treatments the instruments for assessment and ethics approvals. Results : 65 articles were published since 2008. The studies on korean Medicine treatments about traffic accident were mainly published in Journal of Oriental Rehabilitation Medicine. 10 case studies, 14 case series, 11 non randomized controlled trials, 21 randomized controlled trials and 9 systemic reviews had been under research. The most frequently occurred symptoms were neck pain and low back pain. In most studies, various korean Medicine treatments were used to treat the symptoms. Visual analogue scale(VAS) and neck disability index(NDI) were used as primary assessments. In most clinical studies, there were no mention about approval of institutional review board(IRB). Conclusion : In this study, we analyzed the trends of korean Medicine treatments on traffic accident from 2008 to 2012. Reviewing the domestic trends of studies on korean Medicine treatments for traffic accident and examining the strong and weak points of those treatments are essential for the future studies. It is needed to adopt the qualitative methods of evaluation in order to develop a level of evidence.

Objective: Learning the effects of wheelchair posture on center of pressure and lung capacity. Method: Participants were 45 healthy adults. Center of pressure, forced vital capacity (FVC), forced expiratory volume in one second (FEV1), and FEV1/FVC were measured. Results: FVC and FEV1 were significantly decreased in the order of short lordosis posture, normal posture, and slumped posture. Conclusion: Lung capacity reduced the most with slumped posture, and center of pressure was located towards the back. When educating about wheelchair posture, it will be effective to inform patients about keeping a normal posture or short lordosis posture using lumbar support.

최근 신재생에너지 연구개발과 관련하여 소수력발전에 대한 관심이 높아지고 있지만, 기존의 대수력용 수차 시스템과는 달리 소수력에 적당한 수차의 설계법이 아직 확립되어 있지 않기 때문에 고성능의 소수력용 수차의 개발이 요구되고 있다. 그러나, 복잡한 터빈의 구조에 의한 상대적으로 높은 제작단가는 소수력발전용 터빈의 개발에 큰 걸림돌로 작용하고 있다. 따라서, 본 연구에서는 수차의 형상이 상대적으로 간단하고 소수력자원에 적용하기가 용이한 80kW급 횡류형 수차에 대하여 유효낙차 변화에 따른 성능 및 내부유동에 대해서 검토하였다. 유효낙차가 증가함에 따라서 원주방향 및 반경방향 속도비가 증가하게 되며, 증가한 원주속도에 의해 각운동량이 증가하여 출력도 커지게 된다. Recently, small hydropower attracts attention because of its clean, renewable and abundant energy resources to develop. However, suitable turbine type is not determined yet in the range of small hydropower and it is necessary to study for the effective turbine type. Therefore, a 80kW-Class cross-flow turbine is adopted in this study because of its simple structure and high possibility of applying to small hydropower. The result shows that as effective head increases, tangential and radial flow velocities increase and thus, the increased tangential velocity contributes to the increase of angular momentum and output torque.

Viability variation of the second chromosomes of Drosophila melanogaster has been measured from a natural population at Anyang near Seoul. The frequency of drastics (lethal plus semilethal) was about 23 percent. The average viability of all homozygotes was 0.716±0.016, of quasinormals 0.904±0.009, and of random heterozygotes 1.058±0.007. The effective size of the population was estimated at 3,100 by using the rate of allelism (0.021=65/3094). This paper describes a case of stable gene frequency in the past 14 years. The relation of these results to the population size of D. melanogaster was discussed.

The present study examined the development of sentence processing by investigating 4-5-year-old Korean-learning children's and Korean-speaking adults' online and offline parsing pattern of sentences comparable to those used in previous English studies, using visual-world eye tracking paradigm. The results showed that unlike adults, Korean children were more likely to consider a post-positional phrase as a verb goal argument than a noun modifier, making interpretation errors similar to those observed in English-learning children. This was interesting given that verbs appear at the end of sentences in Korean, opposite of English sentences, ruling out the possibility that the interpretation errors observed among English children were due to children' dependency on verb information. The current results suggest that the development of language processing may follow a universal path, independent of the input language characteristics. 비록 구문분석 원리들에 대한 이론적인 합의는 도출되지 않았으나, 다양한 언어권에서 문장처리방식에 대한 연구 결과들은 성인들의 문장처리방식이 대체로 보편적 양상을 지니고 있음을 제시하고 있다. 본 연구는 성숙한 문장처리 능력을 발달시키는 과정에서 아동들이 습득 대상 언어와 무관한 보편적 발달 궤도를 보이는 지, 발달 초기에는 습득 대상 언어에 최적화된 언어-특수적 처리 양상을 보이다가 언어-보편적 양상으로 이동하는지를 검토하고자 하였다. 5세의 영어 습득 아동들이 성인에게서 볼 수 없는 독특한 문장 해석 오류를 보인 문장에 대응되는 한국어 문장을 4-5세의 한국어 습득 아동과 성인에게 제시하고 문장의 의미를 주어진 사물로 시연하도록 하였다. 그리고 문장을 듣는 동안 제시한 관련, 비관련물체들을 응시하는 비율을 측정하여 실시간 문장 해석 패턴도 관찰하였다. 실험결과, 4-5세 한국어 습득 아동이 성인과 다른 문장 해석 오류를 보였는데, 오류의 양상이 영어습득 아동들과 유사하였다. 이러한 결과를 바탕으로 문장처리 발달 과정의 보편성에 대해 논의하였다.
