Objective: To assess the changes of autonomic nervous system in the patients with central and peripheral nervous system lesions using sympathetic skin response(SSR). Method: 55 patient group consisted of 18 stroke, 20 radiculopathy, 10 spinal cord injury, 5 carpal tunnel syndrome and 2 traumatic brain injury. Control group consisted of 22 healthy subjects without neurologic disease. Electrical stimuli were applied over the median nerve at wrist and SSR were recorded simultaneously on bilateral palms and soles. SSR that was not evoked by 5 times of stimulation was considered as no response. Results: 1) 27.7 percent of the patients with stroke and 60 percent of the patients with spinal cord injury showed no response. 2) The amplitudes of SSRs recorded in the affected palms of stroke patients were significantly smaller than these of control group (P<0.05), regardless of stimulation side. 3) The amplitudes of SSRs recorded in the unaffected palm of stroke patients when stimulus was given to the affected side were smaller than these of control group (P<0.05). 4) In the patients with radiculopathy and carpal tunnel syndrome, the latency and amplitude of SSR showed no significant difference compared with these of control group (P>0.05). Conclusion: In central nervous system lesion, the abnormal findings of SSR reflected abnormal ascending and descending pathways of autonomic nervous system. In the patients with radiculopathy, the autonomic nervous system seemed to be maintained normally.

Modern cultural Assets are products of people in the modern society during their ordinary lives of political, economic, social and artistic behavior. They are omnifarious, a little different from the traditional cultural heritage and play an important role and function as a bridge between the old and the new. Studies on how to preserve and utilize the modern architectural heritages have been conducted ceaselessly but it seems that there are not many of them pinpointed on educational architectures. This Study reviewed theories and precedent case studies on architectural characteristics of registered modern cultural assets of domestic college buildings and put a small step to proceed further research on how to securely preserve and effectively utilize those assets in college according to the educational function and the ideology.

뇌기능 장애 환자에서 자세균형 제어능력의 저하는 보행 및 일상생활동작 수행 등에 어려움을 초래하며 이에 대한 정확한 평가 및 치료를 위하여 일상의 환경변화와 유사한 상황을 제공하고 이예 따른 자세제어력을 파악하는 것이 중요하다. 본 연구는 뇌기능 장애환자에서 움직이는 환경에 따른 자세균형제어기능을 정확히 평가하는 환경의 움직임이 자세균형제어에 미치는 영향을 분석하였다. 15명의 뇌기능 장애 환자들과 정상인 15명을 대상으로 실생활과 유사한 환경의 조성을 위하여 HMD를 이용한 가상영상 환경변화(Moving Surround)를 네가지 움직임 종류에 따라 제공하였다. 자세동요의 정도는 힘판을 이용하여 신체압력중심의 변화를 전체이동거리, 동요주파수, 최대 빈도 COP 위치 등으로 측정하였으며 환경의 차이에 따른 변화를 비교 분석하였다. 연구결과 검사 재검사 신뢰도 평가에서 일관된 분석결과를 나타냈고 뇌기능장애 환자와 정상인간의 분석에서는 두 그룹간의 차이를 확인할 수 있었다. 특히 전후로 빠르게 변하는 가상영상 환경에서 가장 큰 자세동요를 나타내었고 통계적으로 유의한 차이가 있었다. 본 연구를 통해 뇌기능 장애 환자에서 가상영성 환경변화가 자세균형제어에 미치는 영향을 확인할 수 있었으며 이러한 환자들을 위한 치료환경 조성 등에도 유용한 자료로 쓰일 수 있을 것으로 사료된다.

In this study, 182 industrial wastewater samples obtained from Gwangju were assigned to 16 industries to investigate the characteristics of organic indexes(TOC, NPOC, COD<sub>Mn</sub>, and DOC). The average COD<sub>Mn</sub> and TOC concentrations by industrial wastewater classification in Gwangju in descending order were as follows : other machinery and equipment manufacturing > painting and other film treatment > textile dyeing, cleaning, and finishing processing. The correlations between TOC and COD<sub>Mn</sub>, NPOC, DOC showed high positive correlation coefficients which were more than 0.8. According to the revised Water Environment Conservation Act 2020 in which COD<sub>Mn</sub> from wastewater discharge facilities was replaced with TOC, a COD<sub>MN</sub> concentration of 130 mg/L in an “Na” region where the volume of wastewater discharge is lower than 2,000 m3/day, corresponds to 75 mg/L TOC, and the concentration ratio of COD<sub>MN</sub> to TOC is 1.73. The average ratio of COD<sub>Mn</sub> to TOC in five metropolitan cities (Gwang, Ulsan, Daejeon, Incheon, and Busan) was 1.55, and the converted TOC concentration corresponding to 130 mg/L COD<sub>Mn</sub> was 84 mg/L. The average measurement ratio of COD<sub>Mn</sub> to NPOC was 1.7, which was close to the COD<sub>Mn</sub> to TOC ratio of 1.73. These results propose that TOC concentration in wastewater discharge from “Na” regions should be changed to 84 mg/L from the current 75 mg/L or TOC concentrations might be applicable to NPOC concentrations in all wastewater discharge facilities.

This study was performed to perceive environmental pollution in children`s playground in Gwangju metropolitan city. Two types of sand and synthetic rubber as flooring material were used in children`s playground. The sampling was collected from 20 sites in sand flooring material and 21 sites in synthetic rubber flooring material. They are measured to evaluate pH, heavy metals, and parasite eggs in sites of sand flooring material and also to heavy metals in sites of synthetic rubber floor material. In site of sand flooring material, pH range was from 5.8 to 8.8. The average concentration of Pb, As, Hg, Cd, and Cr6+ was 16.318, 0.343, 0.048, 0.258, and 0.000 in unit mg/kg, respectively. In site of synthetic rubber flooring material. The average value of the total sum concentration of heavy metals such as Pb, As, Hg, Cd, and Cr6+ was 70.427 mg/kg. This total concentration of heavy metals was even much lower than that of criteria (1,000 mg/kg). The parasite eggs were not found in sites of sand flooring material. Therefore, it showed that all sites in children`s playground was safe environmentally.
