Relationship of Physical Impairment, function and Insulin Resistance in stroke patients

최영은,김지혜,윤영대 한국콘텐츠학회 2013 International Journal of Contents Vol.9 No.3

Insulin resistance is a risk factor for stroke or recurrent stroke. Sedentary behavior increases insulin resistance. This study aimed to identify the relationship between physical impairments and functions and insulin resistance, examining which physical impairments specifically influence insulin resistance the most. The subjects of this study were 63 stroke patients. The subject’s insulin resistance and physical impairments and functions were measured using the Chedoke-McMaster Stroke Assessment (CMSA) and Stroke Impairment Assessment Set (SIAS). The study results exhibited that insulin resistance is statistically significantly related to the variable of foot according to the CMSA(r=.95, p<.05) and to the variable of lower extremity sensory function (touch) in relation to the SIAS(r=.91, p<.05). This study also revealed close correlations between insulin resistance and the variables of ankle control(β=-1.05, p<.05) and low extremity tactile sensations(β=-1.82, p<.05).

The purpose of this study is to analyze the changesinvegetation andflora in the coastal sand dunes and rocks following land-use transformation between 2013 and 2019. The study area is located on Dangjae-bong(hill) on Jin-do island, South Korea andthe area has been developed from aforest area to a resort complex overthe last 3 years. It has been confirmed thatchanges in flora, with 5 species added in the year 2019,have occurred whencompared to the year 2013. Of the five species investigated, four were naturalized plants and one was a terrestrial plant. All of the five species were identified as invasive species, which were caused by the transformationin land-use. There was no change in the specific floristic species, but the number of changed naturalized plants increased from 3 to 7 species. The increase of naturalized plants instead of native plants seems to be the result of invasive species introduced into the coastal sand dunes due to the development and construction. Among the life forms, 7 types of dormant plants turned out to be distributed in the studied area. In the 2013 survey, the ratio of hemigeophytes (H) was the highest (34.04%), followed by geophytes (G), therophytes (Th) and homomorphic therophytes (Th(w)). However, in the 2019 survey, three out of five species were homomorphic therophytes, the second highest next to hemigeophytes. The costal dune vegetation was classified into 7 communities in the study area. There were changes of the dominance index and species compositions in vegetation between 2013 and 2019. With regard to changes in the abundance of plants, Carex kobomugi, Calystegia soldanella, and Lathyrus japonicus, all of which are the typical components of coastal sand dune vegetation, have decreased while Rosa wichuraiana and Vitex rotundifolia, which are naturalized plants and woody invasive species, have increased. The findings of this research demonstrate that frequent anthropogenic disturbances from the change of land-use in areasadjacent to the coastal sand dunes caused to alter the abundance of such species. However, it was confirmed that there were no changes in abundance of Limonium tetragonum, Suaeda asparagoides, and Zoysia sinica, which are found relatively close to the beach. This is deemed to bebeca use the most invasive species of the coastal sand dune areas are much less tolerant of salinity that intrusion into the areas affected by seawater does not allow their growth. As for the diversity of species, the diversity index ofthe 3 types was higher in 2019 than in 2013, but the gap of the plant species diversity index was very small. The increase in species diversity of dune vegetation is due to the invasion of coastal sand dunes due to land transformation rather than to the stability of vegetation. 본 연구는 사구주변지역의 레저산업단지조성 등과 관련한 토지이용변화에 따른 해안사구식생의 변화를 연구하기 위하여, 전라남도 진도 의신면 당재봉 일대 해안사구에 대한 식물상, 식생, 종다양성의 변화를 분석한 것이다. 전라남도 진도 당재봉 일대 토지이용변화(2016~2019년에 걸친 개발로 산림지역이 리조트 단지로 변화하였음)에 따른 해안사구 와 해안암석 등에 서식하는 식생 및 식물상의 변화를 분석하기 위해 2013년도와 2019년도에 조사를 실시하였다. 식물상의 변화는 2013년도에 비해 2019년 조사에서 5종이 추가 조사되었다. 추가 조사된 5종 중 4종은 귀화식물이며, 1종은 육상식물로서 5종 모두 토지이용 변화에 따른 침입종들로 나타났다. 식물구계학적 특정종의 변화는 일어나지 않았으며, 귀화식물의 변화는 3종에서 7종으로 증가하였다. 자생식물의 증가보다는 귀화식물이 증가한 것은 개발로 인한 침입종들이 해안사구에 유입된 결과로 보인다. 생활형은 7개 유형의 휴면형을 나타내는 식물이 분포하고 있는 것으로 나타났으며, 2013년 조사에서는 반지중식물(H)이 34.04%로 가장 많았으며, 지중식물(G), 1년생식물(Th), 동형1년생식물(Th(w)) 순으로 많았다. 그러나 2019년 조사에서는 동형 1년생식물이 5종 중 3종으로서 반지중식물(H) 다음으로 분포비율이 높았다. 해안사구식생의 식물군락은 총 7개 군락으로 구분되어졌으며, 2013년도에 비해 2019년 조사에서 우점도와 종조성의 변화가 있었다. 식물의 수도변화는 해안사구 식생의 전형적 구성종인 통보리사초, 갯메꽃, 갯완두 등은 감소하였으나 귀화식물과 목본류 침입종인 돌가시나무와 순비기나무는 증가하여 해안사구 주변의 토지이용 변화에 의한 인위적인 빈번한 간섭이 이들 종의 수도변화를 일으킨 것으로 사료된다. 그러나 비교적 해안 바닷가와 근접해서 서식하는 갯질경, 나문재, 갯잔디 등은 변화가 없는 것으로 나타났다. 이러한 현상은 이 지역 해안사구 침입종들의 대부분이 염도에 내성이 크지 않기 때문에 바닷물에 영향을 받고 있는 지점으로의 침입이 허용되지 않았기 때문이다. 종다양성은 2013년에 비해 2019년에 3종류의 종다양성 지수가 높게 나타났으나 종다양성 지수의 차이는 매우 작았다. 식생의 종다양성의 증가 현상은 식생의 안정성에 의한 결과 보다는 토지이용 변화에 따른 해안사구현상의 교란이 종 침입의 결과로 나타났기 때문이다. 따라서 본 연구에서 나타난 결과를 보면 이들 침입종은 해안사구 식생의 종구성, 생활형, 수도(abundance), 종다양성의 변화 등을 유발하였으며, 해안사구 식생의 천이진행을 매우 빠르게 유도하여 해안사구식생 종구성의 전형성을 크게 변화 시킬 것으로 예상된다.

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.

최영인 ( Young In Choi ),노정석 ( Jung Suk Roh ) 대한스포츠의학회 2016 대한스포츠의학회지 Vol.34 No.1

The purpose of this study were to examine the effects of the speed of sidestep in a specific direction on the kinematic variables of the lower extremities and to provide basic information on sidestep. The subjects of this study were eight students at Hanseo University who did not have a problem in lower extremity alignment. Biomechanical data were collected using a motion analysis system and force plate and Kruskal-Wallis test was performed in order to test differences according to speed. The results of this study were as follow. First, as to hip joint angle according to speed, when the speed increased, in the sagittal view, the maximum flexion angle decreased, the range of motion (ROM) decreased, and the flexion angle at the highest ground reaction force decreased, and in the transverse view, the internal rotation angle at the highest ground reaction force increased. Second, as to knee joint angle according to speed, when the speed increased, in the sagittal view, the maximum flexion angle decreased, the ROM decreased, and the flexion angle at the highest ground reaction force decreased, and in the coronal view, the maximum varus angle decreased, and the ROM decreased. Third, as to ankle joint angle according to speed, when the speed increased, in the sagittal view, the ROM decreased, and the dorsiflexion angle at the highest ground reaction force decreased, and in the coronal view, the minimum inversion angle increased. This suggests that high-speed sidestep during a game increases the risk of injury and degenerative arthritis among athletes.

This study aims to examine the effect of 8-week 11+ program on technical skills and balance abilities of high school soccer players. This study targeted 40 soccer players from G and K club in Gyeonggi-do and 20 players from G team and 20 players from K team were placed in the training group and the control group, respectively. For data analysis, variable values of the two groups before and after intervention were calculated as averages and standard deviations using the SPSS ver. 21.0 statistic program. For analyzing within-group differences, paired t-test was conducted and for analyzing between-group differences, independent sample t-test was conducted. The statistical significance level was set at 0.05. The major study findings are as follows. First, the 11+ program was more effective in improving Jug 200 and short pass ability than static stretching. Second, the 11+ program was more effective in the posteromedial and posterolateral areas of Y-balance test than static stretching. These results demonstrate that the 11+ program is relatively effective in improving technical skills and balance abilities of soccer players. Therefore, it is considered that it is important to introduce and distribute the 11+ program to leaders, who are responsible for enhancing skills of soccer players.
