Many institutes such as Bank of Korea, Samsung Economic Research Institute and Chamber of Commerce announced Entrepreneurship Index models. But, due to the arbitrary measurement model and the survey of each institute, there is a misled in the understanding and model of entrepreneurship. In addition, there is no research about comparative study of Entrepreneurship Index until now. In this study, we suggest our own Entrepreneurship Index model based on the literature review of Entrepreneurship Index. This model enables the objective measurement of Entrepreneurship Index. Above all, we suggest advantages and disadvantages of existing Entrepreneurship Index model systematically and the direction of Entrepreneurship Index.

The purpose of this study was to examine the effects of rhythmic auditory stimulation (RAS) on gait parameters, with and without the presence of a melody, for adolescents with traumatic brain injury (TBI). Three adolescents with TBI received a total of ten individual RAS training sessions. At pre and posttest, spatiotemporal parameters including cadence, velocity and kinematic parameters were measured using the VICON 370 Motion Analysis System. The results showed no significant difference in gait velocity between the two conditions, thus the presence of the melody condition did not impact the outcome of RAS gait training. On the other hand, all participants showed improvement in gait function after RAS training. The cadence, velocity, stride length, and symmetry were increased and the stride time was reduced after training. The motion analysis demonstrated that the movement patterns of hip and knee joints improved, as they were more similar to normal gait, which indicates that the walkings tance became more stable. The research findings indicate that rhythm is the primary factor in mediating gait functions via RAS training. This study also supports that RAS training can effectively improve the gait function for adolescents with TBI.

Elytra of Harmonia axyridis exhibit varied color patterns. In the present study, we deciphered the genetic basis for intraspecific diversity of elytra color patterns in H. axyridis, using amplified fragment length polymorphism (AFLP). Twenty-eight AFLP reactions were performed to generate a total of 2,741 bands. Of these, 20 bands were polymorphic for each color pattern. The polymorphic bands showed differences of genetic character among different color patterns of H. axyridis. Among them, ten candidate AFLP markers were color-linked. S1, S2, and S20 markers were detected in Succinea 1 and 2 variants of H. axyridis, whereas S3 and S5 were specifically detected in the Conspicua variant. S15, S18, and S19 were specific to the Succinea 2 variant. Polymerase chain reaction (PCR) products of these ten AFLP markers were sequenced. BLAST analysis of these sequences against the GenBank database revealed their homology to DNA fragments of unknown function. Based on the color-linked AFLP markers, sequence characterized amplified region (SCAR) markers were designed for PCR amplification of genomic DNA. Of the ten AFLP markers, five were successfully converted into SCAR markers, which could discriminate elytra color polymorphism in H. axyridis.

The population is concentrated in the metropolitan areas in Korea, and low-density residential areas are transforming into high density residential areas through redevelopment to meet this demand. However, large-scale redevelopment in a short period of time has a negative impact on the urban climate, such as generating a heat island effect due to the reduction of urban green areas. In this study, the change in surface temperature from 2013 to 2022 in the redevelpment areas of Godeok-dong and Dunchon-dong, Gangdong-gu, Seoul, was analyzed using Landsat 8 satellite images. In the Godeok-dong area, the difference in surface temperature was analyzed for the target redevelopment area, forest area, mixed forest and urban area, and low density residential area. In the Dunchon-dong area, the difference in surface temperature was analyzed for the target redevelopment area, forest area, and low density residential area. The difference in surface temperature was analyzed through multiple regression analysis conducted yearly over the three different stages in redevelopment period. The results from the multiple regression analysis show that in both areas, the land surface temperature of target redevelopment area was higher than that of the forest area and lower than low density residential area. It can be seen that these results occurred because the low-density residential area in Godeok-dong and Dunchon-dong had a lower green area ratio and a higher building-to-land ratio than the target redevelopment area. The results of this study suggest that even if low-density residential areas are transforming into high-density areas, adjusting the management of green areas and building-to-land ratio can contribute to lessen urban heat island effect.

As a new duty of universities, contributions to localities and regions are magnified as an important issue and overseas universities are creating it as the index to use self evaluations and public relations actively. The universities in Korea are expanding resources usage of university and proceeding various businesses to enhance co-operation with local government, civic groups and companies lately. However, it is still in an embryo. This study is aiming to analyze cases of foreign universities and the socio-economic impacts of university on the region and discover evaluation index based on the results to be applied to the universities in Korea. This study had considered the evaluation of local effect by the university conducted by the Higher Education Funding Council for England(HEFCE) which is the representative case to analyze the impacts of university on the region at the level of government and independent organizations. The applicable common index had been extracted for universities in Korea from case studies on University of Rochester in the US and University of Birmingham in the UK considered as a representative university in North America and Europe respectively which are publishing a white paper on local and regional impacts of the university by using various index. As a result, 24 items in six areas(economic influence, research, education, art & cultural services, regional development, and the field of university specialization) had been deducted as the evaluation index which represents the local and regional impacts of university. This index could be secured through holding materials of each university and 'Higher Education in KOREA' as university information disclosure service and it might be applied to the universities in Korea.

In this research, we propose a document recommendation method which can find documents that are relatively important to a specific document based on citation information. The key idea is parameter tuning in the Neumann kernal which is an intermediate between a measure of importance (HITS) and of relatedness (co-citation). Our method properly selects the tuning parameter ${\gamma}$ in the Neumann kernal minimizing the prediction error in future citation. We also discuss some comutational issues needed for analysing large citation data. Finally, results of analyzing patents data from the US Patent Office are given.

As an exploratory research to understand the nature of relationships between harbors and their neighboring communities, this study analyzes how harbors influence their residents' quality of life(QOL). The QOL was measured by 18 indicators reconstructed by reviewing relevant literatures. As a result, both Busan and Incheon were found to have statistically significant influence on many of QOL indicators including general expenditure per capita, number of manufacturing factories per capita, rate of housing supply, number of financial agencies per capita, number of cultural assets per capita, number of schools per capita, number of sick-beds per capita, and the size of welfare expenditure per capita.

기술력평가는 기술사업화 주체가 기술을 사용하여 수익을 창출할 수 있는 능력을 평가하기 위한 것으로, 국내 기술성 평가기관들이 각자 독자적인 평가 모형을 활용하여 평가를 수행해오고 있다. 특히 최근에 개발된 해양 및 수산 산업 분야의 기술력 평가모형은 타 산업 대비 열악한 기술개발 환경과 연구개발 성과를 대상으로 평가를 수행해오면서 기존의 평가체계 내에서는 많은 평가대상 기술들이 부적합 판정을 받아오고 있었다. 이러한 것은 기존 평가체계가 타 산업에서 활용되고 있는 공통적인 평가지표와 평가척도를 유사 또는 동일하게 사용하면서 발생되는 문제점으로 인식되었고, 또한 해양 및 수산 산업의 특수성이 반영되지 않은 평가체계에서 비롯된 것으로 파악되고 있다. 따라서 본 연구를 통해 기존 평가체계를 해양수산 산업의 특수성을 반영할 수 있는 평가체계로 개선하여 해당 산업에 특화될 수 있는 평가체계를 새롭게 제안하고자 하며, 이를 위해서 기존 평가지표의 개선, 시뮬레이션 기반의 평가척도의 재설정 방법과 평가등급 산출방법에 대한 새로운 제안을 하고자 한다. 마지막으로 개선된 기술력평가 체계를 활용하여 시범사례평가를 수행하여 기존 평가체계를 통한 평가결과의 Gap분석을 수행하고자 한다.

This study was an examination of the relevance and clinical significance of electroencephalographic (EEG) indexes (e.g., mental/physical stress and attention) and indexes of heart rate variability (HRV) with regard to cognitive function and physiological health conditions in elderly people. A device was used to record two-channel EEGs of the frontal lobe and a one-channel ECG simultaneously. Subjects were 76 people average aged 73. The significant findings are as follows: First, subjects whose intrinsic alpha rhythm had high amplitude, regardless of peak, showed higher resistance to mental stress and lower physical stress than did subjects with low-amplitutde intrinsic alpha rhythm. Second, HRV, SDNN, and RMSSD indexes showed strong positive correlations between the two groups of subjects regardless of the division of groups. Third, the alpha asymmetry of the left and right sides of the brain in subjects with low-amplitude intrinsic alpha rhythm was larger, and the delta/alpha ratio (reflecting physical stress) and theta/sensorimotor rhythm (SMR) ratio (showing the decline in attention) were bigger. Fourth, the subjects in whom intrinsic alpha rhythm peak occurred during slow rhythm had a higher theta/SMR ratio than did subjects whose peak occurred during fast rhythm, which was related to a steeper decline in attention. Therefore, the presence or absence of intrinsic alpha rhythm peak and amplitude on quantitative EEG may be an index reflecting the cognitive function and physiological health of elderly people.
