This article investigates from a critical discourse studies perspective the news media representations of inbound international students in Korean higher education. In light of the ideological workings of discourse and the media's social impact on the public consciousness, the current study examines the structures and detailed meanings of the media portrayals of international students as regards the three dimensions of the textual feature, discursive practice, and social practice. The findings suggest that the media representations of international students are racialized according to stratified power relations in the context of Korean higher education, and that the racialization and stratification is undergirded by neoliberal capitalist ideology of internationalization, ambivalent diversity discourse of Others, and benevolent care discourse of the minoritized. A range of discursive othering strategies are deployed in the news texts to render more newsworthy the reported issues and incidents concerning international students. The article concludes and argues that more fluid approaches to diversity should be developed to account for the complexity and multiplicity of transnational subjectivities.

The number of healthy older adults is rapidly increasing recently owing to the increase of the elderly population. Therefore, programs for improving the cognitive functions of these healthy seniors are actively being expanded. This study aimed to prevent the decline of cognitive function due to aging by applying a program enhancing cognitive functions to healthy older adults. The objective of this study was to evaluate the effects of Korean computer-based cognitive rehabilitation program (CoTras), which is commonly used in cognitive therapy for the aging, on the memory of the elderly. The subjects had scored at least 24 points in MMSE-K. CoTras was applied once a week (30 minutes) for one month. Electronic pegboard programs were used as an evaluation tool: order memory (difficulty=low) and location memory (difficulty=medium). The order and location memories were compared before and after the intervention. The Wilcoxon signed rank-sum test was used for the study at the significance level of α=.05. The results showed that CoTras significantly improved order memory and location memory. Therefore, CoTras can be applied to the healthy elderly for improving that memory improvement training has a positive impact on healthy older adults result in the development of memory enhancement programs can be expanded in the future.

This neurological damage accelerates the infection reaction of cells and apoptosis at the time of reperfusion after ischemia occurs. BCL-2/BCL-2 allogeneic begeminum has a function of suppressing the apoptosis of cells, and thus it is inferred that the susceptibility of cells to apoptosis is determined by the amount of allogeneic begeminum present which is determined based on the amount of BAX. Ischemia was induced in SD mice by occluding the common carotid artery for 5 minutes, after which blood was re-perfused. NEES was applied to acupuncture points, at 12, 24, and 48 hours post-ischemia on the joksamri, Hapgok. Protein expression was investigated through BAX antibody immuno-reactive cells in the cerebral nerve cells and Western blotting. The results were as follows: In the present study as well, as a result of observation of the change in the number of the BAX reaction cells after the inducement of GI, there was the aspect of most of the BAX reaction cells being observed in the corpus striatum area of the GI group 24 hours after the inducement of ischemia. This revealed the same results as those of previous studies in which the change in the number of BAX reaction cells occurred in all areas while ischemia was in progress. The change in the expression of BAX protein after 24 hours showed that there was a very significant reduction in the NEES group compared to the GI group (p<.01). As a result, a greatest amount of change in the number of BAX immunoreactive cells related to apoptosis 24 hours after ischemia appeared in the NEES group. This study that ischemia increases the expression of BAX that induces apoptosis. Thus, it is determined that ischemia is the main cause of the apoptosis of neurons, and this study reveals that low frequency needle electrode electrical stimulation has the effect of blocking the apoptosis of neurons by reducing protein related to the apoptosis of cells that has increased after ischemia has occurred.

The purpose of the present study is to provide exercises, together with music, that are helpful for elderly people’s balancing ability, and to determine their effects in order to provide data for the promotion of elderly persons’health. Thirty elderly persons were randomly assigned to a balance training group(BTG) of 15 subjects, or a music and balance training group (music therapy + balance training [MTBTG]) of 15 subjects; intervention was implemented three times per week for six weeks. To measure the changes in their balancing ability before and after the experiment, the limit of stability, the“Timed Up and Go”(TUG) test, and the Berg Balance Scale (BBS) were measured. Changes in the limit of stability before and after the experiment were shown to be significant in both the BTG and the MTBTG. Changes in the limit of stability of the right side before and after the experiment showed statistically significant differences between the BTG and the MTBTG. Changes in the TUG test and the BBS before and after the experiment were shown to be statistically significant in both the BTG and the MTBTG. The application of music during balance training thus is considered to have a positive effect on elderly persons’balancing ability.

The cerebellum is known to control balance, equilibrium, and muscle tone. If the cerebellum becomes damaged, the body is unable to retain its balancing functions or involuntary muscle movement. This is why, in stroke patients, there is a high risk of functional disability, as well as a myriad of other disabilities secondary to stroke. Ischemia was induced in SD mice by occluding the common carotid artery for 5 minutes, after which blood was reperfused. Needle electrode electrical stimulation(NEES) was applied to acupuncture points, at 12, 24, and 48 hours post-ischemia on the joksamri. Protein expression was investigated through caspase-3 antibody immuno-reactive cells in the cerebral nerve cells and Western blotting. The results were as follows: The number of caspase-3 reactive cells in the corpus cerebellum 12 and 24 hours post-ischemia was significantly (p<.05) smaller in the NEES group compared to the GI group. caspase-3 expression 12 and 24 hours post-ischemia was significantly(p<.05) smaller in the NEES group compared to the GI group. Based on these results, NEES seems to have a significant effect on Caspase-3 in the cerebellum in an ischemic state at 12 and 24 hours post ischemia, NEES delays the occurrence of early stage apoptosis-inducing Caspase-3, delaying and inhibiting apoptosis. Further systematic studies will have to be conducted in relation to the application of this study’s results on stroke patients.

Ischemia, the leading cause of strokes, is known to be deeply related to synaptic plasticity and apoptosis in tissue damage due to ischemic conditions or trauma. The purpose of this study was to research the effects of NEES(needle electrode electrical stimulation) in brain cells of ischemiainduced rat, more specifically the effects of Poly[ADP-ribose] polymerase(PARP) on the corpus striatum. Ischemia was induced in SD mice by occluding the common carotid artery for 5 minutes, after which blood was re-perfused. NEES was applied to acupuncture points, at 12, 24, and 48 hours post-ischemia on the joksamri, and at 24 hours postischemia on the hapgok. Protein expression was investigated through PARP antibody immuno-reactive cells in the cerebral nerve cells and western blotting. The number of PARP reactive cells in the corpus striatum 24 hours post-ischemia was significantly(p<.05) smaller in the NEES group compared to the global ischemia(GI) group. PARP expression 24 hours post-ischemia was very significantly smaller in the NEES group compared to the GI group. Results show that ischemia increases PARP expression and stimulates necrosis, making it a leading cause of death of nerve cells. NEES can decrease protein expression related to cell death, protecting neurons and preventing neuronal apoptosis.

The purpose of this study was to investigate the influence of handicraft activities on hand promptness and grasp in the elderly. Subjects were comprised of 14 senior citizens between the ages of 70-85, with 7 subjects in the experiment group and 7 in the control group. Subjects in the experiment group practiced various handicrafts twice a day, while those in the control group did not participate in any special activity. The Jebsen Taylor Hand Function Test was used to evaluate the results, while a dynamometer and pinch gauge were used to measure hand promptness and grasp. The 7 senior citizens in the experiment group were able to increase their hand promptness and grasping skills. Conclusively, handicrafts can help improve hand promptness and grasp in the elderly. Furthermore, the development and improvement of such skills can have a positive influence on the daily lives of senior citizens. Such skills are expected to improve the overall neuro-function in the elderly population.

대나무를 이용하여 화훼장식품을 개발하고 그 작품을 전시하였다. 대나무의 길고 굵은 가지를 교차시켜 현대적 디자인을 하고 그 사이에 식물을 고정시켜 작 품성을 높였다. 대나무 선단부의 긴 가지와 잎을 밀집 시켜 숲을 만들고 그 속에 안정감 있는 분화류를 배 치하였다. 대나무를 세로로 잘라 기둥을 만들고 그 선 단부에 대나무 용기를 부착시켜 식물을 심었다. 대나무 기둥의 움직임에 의한 리듬감을 표현하였다. 대나무의 잔가지들을 서로 엮어 면을 만들고 그 면에 식물을 매 달아 벽장식 작품을 구성하였다.

화훼장식품 제작 시 플로랄 폼은 쉽게 썩지 않기 때문에 감상기간 이후 심각한 환경문제를 발생시키는 문제점을 지니고 있다. 본 연구를 통해 플로랄 폼을 사용하지 않고 화훼 고유의 부분별 특성을 살려 여러 가지 효과적인 꽃의 고정형태를 디자인하였다. 화훼장 식의 표현기법 연구를 위해 가지, 줄기, 잎, 열매, 꽃, 뿌리 등 식물소재 고유의 형태적, 재료적인 특성을 파 악하였다. 이를 통해 화훼의 각 부분이 가진 다양한 조형적 특성을 활용하여 꽃을 고정시키는 여러 가지 기법으로 작품 제작에 적용하였다. 본 연구를 통해 환경문제를 야기할 수 있는 인공적 인 부자재인 플로랄 폼 대신 꽃의 각 부분의 특성을 살려 여러 가지 기법을 제안하였다. 화훼장식의 미적 측면뿐만 아니라 제작 후 발생하는 환경문제에 대한 대안을 제시하고 화훼장식에서의 활용 매체를 다양화할 수 있었다. 특히 일상생활에서 쉽게 구할 수 있는 자 연소재를 이용하여 누구나 쉽게 디자인할 수 있으므로 화훼장식 저변 확대에도 기여할 수 있다. 앞으로 우리 주변의 작은 소품에서부터 공간장식으로까지 그 활용범 위가 확대될 것으로 기대된다. 이러한 화훼 고유의 특 성을 살린 표현 기법의 지속적인 연구, 개발을 통해 자연친화적인 개념의 화훼장식이 확대되어야 한다.

성인 남녀의 분변과 시판 요구르트로부터 분리한 10주의 균주들을 밤용액에 접종 발효하고 산생성과 생균수 면에서 각각 우수한 Lactobacillus spp. PAPI과 MGG2를 분리하였다. 발효액의 저장 중 균수는 발효액의 산도에 의존하였고 산도를 낮추었을 때 생균수는 증가하였다. 이들을 혼합 배양하였을 때 발효제품의 산도와 생균수는 각각의 단독배양액에 비하여 더 컸으며 3주간 저장 후 생균수도 100배 이상 컸다. 밤 용액의 발효에서 이들을 상업용 수입 종균제품과 비교하였을 때 24시간 배양에서 생균수가 더 많았다.
