Objective : The purpose of this study was to verify the effects of auditory stimulus using music on unilateral neglect in patients with stroke. Methods : This study used a single subject (ABA) design. The subject who showed unilateral neglect caused by stroke received auditory stimulus using music for 60 minutes per sessions. A total of 20 sessions were conducted. The unilateral neglect was measured by the Star cancellation test and Line bisection test during each session, and Catherine Bergego Scale was used to evaluate the degree of unilateral neglect in daily life pre-and post-test. Also, Positive Affect and Negative Affect Schedule was used to test subject's emotional status. Results : During the intervention period, the results of the Star cancellation test and Line bisection test showed the trend of reduction of unilateral neglect symptom and the effects of intervention were maintained after intervention. After intervention, the results of CBS indicated decreased unilateral neglect symptom in activities of daily living and the results of PANAS indicated increased positive affect. Conclusions : The result of this study indicate that auditory stimulus has a positive effect on the unilateral neglect, and may be considered as alternative choice in clinical occupational therapy for reducing unilateral neglect.

Objective: This study aim is to identify whether 30minutes optokinetic stimulation(OKS) with smooth pursuit eye movement can alleviate chronic hemispatial neglect. Methods: We applied optokinetic stimulation with smooth pursuit eye movement to 2 chronic hemispatial neglect patients. experimental duration was total 4weeks - 1week baseline, 2weeks OKS intervention, 1week 2nd. baseline. The intervention was 10 OKS sessions (30min each, 1session daily, from Monday to Friday) over a period of 2weeks. The neglect test carried out 3 times a week every other day. The OKS was provided on the screen when patient sat in front of the screen(13.5 inch). The OKS video that the 24 yellow squares moving coherently from the right to the left side. Patients were instructed to perform smooth pursuit eye movement without head and neck movement. Results: As a result of the OKS for 2weeks, the degree of neglect trends to decrease on both 2 cases compared to baseline A. The degree of the neglect of subject 1 tended to increase the at the baseline A. In contrast, the subject 2 showed that tendency that the degree of the neglect declined additionally at the baseline A. Conclusions: We identified that 30 minutes optokinetic stimulation with sooth pursuit eye movement is effective intervention method for chronic hemispatial neglect.

Objective : This study aim is to identify whether smooth pursuit eye movement(SPEM) using portable device can alleviate chronic hemispatial neglect. Methods : We applied smooth pursuit eye movement to one chronic hemispatial neglect patient. Experimental duration was total 4weeks - 1week baseline, 2weeks SPEM intervention, 1week 2nd. baseline. The intervention was 10 SPEM sessions (30min each, 1session daily, from Monday to Friday) over a period of 2weeks. The neglect test carried out 5 times a week. The SPEM was provided on the screen when patient sat in front of the screen(8.4 inch tablet pc, distance 40cm). The SPEM video that the 24 yellow squares moving coherently from the right to the left side. Patients were instructed to perform smooth pursuit eye movement without head and neck movement. Results : As a result of the SPEM for 2weeks, the degree of neglect tended to decrease compared to baseline A. The degree of the LBT tended to increase the at the baseline A'. In contrast, the SCT showed that tendency which the degree of the neglect maintained at the baseline A'. Conclusion : We identified that SPEM using portable device is effective intervention method for chronic hemispatial neglect.

Radish is one of the major vegetable crops and has been damaged economically by the causal agent of Fusarium wilt disease, Fusarium oxysporum f. sp. raphani (FO) in the highlands of Gangwon province, Korea. Recently, clover cyst nematode, Heterodera trifolii(HT), occurred in highland of Jeongseon area and poses a threat to radish plants. The nematodes, besides causing direct damage to radish plants, possess the capability to synergize with other plant pathogens, leading to the development of a disease complex. The aim of this study was to investigate the interaction between FO and HT in radish plants. The length of plants co-infected with both FO and HT was shorter than that of plants infected with FO alone, but there was no statistically significant difference. However, the disease severity was much higher in the plants co-infected with both FO and HT(1.60±0.97) compared to FO alone(0.20±0.42)(df=3, F=10.17, p<0.001). Disease incidence was also about two-fold higher in plants co-infected with both FO and HT (80%) compared to FO alone (44%). These results suggested that the clover cyst nematode should be considered in the management of Fusarium wilt disease in the highlands of Gangwon province.

To improve the problem of strength reduction of unary and binary blended non-cement concrete that occur at room temperature, comparative analysis was conducted based on the slump and compressive strength properties of ternary blended non-cement concrete in which cement was replaced with silica fume, fly ash, and blast furnace slag, and the following conclusions were drawn. The ternary blended non-cement concrete showed higher compressive strength than binary binder concrete, and the slump reduction was less when 10% silica fume was mixed. In addition, the appropriate composition ratio range of each by-product was suggested according to slump and compressive strength level based on ternary diagram.

편측무시란 뇌졸중 환자에게서 나타나는 지각 손상의 한 종류로 말초 운동 및 감각 신경의 손상과 상관없이 손상된 대뇌반구 반대변의 공간과 신체의 지각이 감소된 증상이다. 현재 편측무시환자에 대한 치료는 환자가 책상에 앉아 팔과 손가락만으로 치료를 하는 소운동적인 방법으로 한 가지 치료효과만 기대할 수 있고, 환자들 또한 지루함과 피곤함을 쉽게 느끼게 된다. 또한, 서서 활동하기 힘든 편측무시환자들은 적당한 재활/치료방법이 없고, 안전성 측면에서도 여러 가지 문제가 발생할 수 있다. 따라서 본 논문에서는 편측무시환자들이 앉아서 안전하게 재활/치료할 수 있는 재활도구를 개발하고자 한다. 특히, 지루한 재활프로그램에 게임요소들로 동기 및 흥미 유발하여 지속적으로 재활/치료를 하며 압력센서 기반의 시각재활과 신체재활의 복합적인 재활을 연구하고자 한다.

어린이 문제에 있어서 항상 그렇듯이 아동도서에는 '안됨'이라는 용어가 너무 난무하다. 과학입국을 부르짖으면서 공상과학소설은 허무맹랑해서 안되고, 할아버지의 무릎에서 자신은 무시무시한 옛날 이야기를 즐겼으면서 괴기소설은 안되고, 추리소설은 비인간적이니 안되고, 삽화가 만화적이어도 읽어서는 안된다고들 말한다.

지금 우리가 절망의 시대, 혼돈의 시대를 살고 있다는 것은 분명한 사실이다. 시는 이러한 조건을 무시할 수 없고 무시해서는 안된다. 그러나 일상에 발이 묶여 인식의 해방을 꾀하지 못한다면, 시는 어설픈 잠언에 빠지고 우리사회의 흐름처럼 퇴행하고 말 것이다. 한용운, 이육사 등의 시적 성취가 주는 교훈을 되새겨 볼 일이다.

This study's aim was to confirm that pseudoneglect affects visual attention through car laterality, using a driving simulator with either bisection or quadrisection strategies being applied to road usage. On the pencil and paper tests, the left quadrisection and bisection marks deviated significantly to the left. While driving, the car was significantly lateralized to the right of the lane regardless of conditions. However, in terms of relative laterality, the biggest left laterality occurred on roads 1(bisection), while the smallest left laterality occurred on roads 2 (right quadrisection). Thus, the effect of pseudoneglect was demonstrated in both the pencil and paper tests and the driving simulation task. Also, roads 2 and 4, which were driven on the right side of the lane, showed a tendency for drivers to avoid the centerline, as this was the expected cause of right laterality. This study demonstrated that the pseudoneglect phenomenon can occur in a routine driving task.

This research aimed to investigate the effects of neurofeedback training on unilateral neglect and depression in patients with stroke. Fourteen of the subjects were selected from the experimental group and the control group respectively; the following results were obtained. First, experimental group and the control group presented significant statistical difference before and after intervention on neglect. However, there is after intervention no significant statistical among them. Two, experimental group and the control group presented significant statistical difference before and after intervention on depression, and the experimental group demonstrated more decrease than the control group in depression. The results obtained from this research expect us that applying the neurofeedback training for the improvement of neglect and depression, to stroke patients has a positive effect on the rehabilitation of patients.
