Ma Min Kyeong,Cho TaeHwan,Lee Joo Won,Moon Hyun Im 대한재활의학회 2023 Annals of Rehabilitation Medicine Vol.47 No.4

Objective: To investigate the relationship between the torque onset angle (TOA) of the isokinetic test for knee extensors in the paretic side and walking related balance in subacute stroke patients.Methods: We retrospectively reviewed patients with first-ever strokes who have had at least two isokinetic tests within 6 months of onset. 102 patients satisfied the inclusion criteria. The characteristics of walking related balance were measured with the Berg Balance Scale sub-score (sBBS), Timed Up and Go test (TUG), 10-m Walk Test (10MWT) and Functional Independence Measure sub-score (sFIM). The second isokinetic test values of the knee extensor such as peak torque, peak torque to weight ratio, hamstring/quadriceps ratio, TOA, torque stop angle, torque at 30 degrees, and peak torque asymmetry ratio between paretic and non-paretic limb were also taken into account. Pearson’s correlation, simple regression and multiple regression analysis were used to analyze the correlation between TOA and walking related balance.Results: TOA of the knee extensor of the paretic limb showed significant correlations with BBS, sBBS, TUG, 10MWT, and sFIM according to Pearson’s correlation analysis. TOA also had moderate to good correlations with walking related balance parameters in partial correlation analysis. In multiple regression analysis, TOA of the paretic knee extensor was significantly associated with walking related balance parameters.Conclusion: This study demonstrated that TOA of the paretic knee extensor is a predictable parameter of walking related balance. Moreover, we suggest that the ability to recruit muscle quickly is important in walking related balance.

화학물질은 종류에 따라 취급방법과 사고 대응방법이 상이하며, 사고 발생 시 유해⋅위험성이 매우 크다. 따라서 사고 피해를 최소화하기 위해서는 물질의 특성을 인지하고 그에 따른 적절한 대응방법 을 대응자가 사전에 숙지하여 화학사고 발생 시 최적의 대응활동을 수행할 수 있어야 한다. 이를 위해서는 대응역량과 전문성을 확보하기 위한 교육훈련이 필수적이지만 국내의 경우 화학재난대응 에 대한 교육 프로그램이 선진화된 국외의 교육 시스템에 비해 다소 미흡한 실정이다. 따라서 본 연구에서는 미국, 영국, 캐나다 등의 국외 주요 국가와 화학물질안전원, 중앙소방학교 등 국내 대응 기관의 화학재난대응 교육 현황 및 국제적인 화학재난대응 교육지침인 NFPA472를 조사⋅분석하고, 국내 화학사고 대응기관의 역할과 실질적으로 사고대응을 수행하기 위한 교육 수요자의 의견을 수 렴⋅분석하여 이를 바탕으로 국내 실정에 맞는 수요자 맞춤형 화학재난대응 교육 프로그램을 제시 하였다. The methods of handling chemical substances and responding to the accidents vary by the types of chemical substances. As it is very harmful and dangerous in the event of an accident, it is necessary to recognize the properties of the chemical substances and to use appropriate counter measures to minimize accident damage. Education and training programs are essential to enhance response capacity and expertise, but educational programs on chemical disaster response have been insufficient in Korea. Therefore, in this study, we analyzed the current status of educational programs in response to chemical disasters in several countries including United States, UK and Canada. We also investigated NFPA 472, the international guideline for responding to chemical disasters, and analyzed the roles of responding organizations along with the opinions of participants in the educational programs in Korea. Based on these analyses, we presented a consumer- customized chemical disaster response education program tailored to the domestic situation in Korea.

The optimal screening condition for evaluating resistance against inoculation of gray mold (Botrytis cinerea) was investigated on 8 different grapevines (Vitis spp.) varieties such as ‘Thompson Seedless’, ‘Reliance’, ‘New York Muscat’, ‘Alden’, ‘Golden Muscat’, ‘Sheridan’, ‘Concord’, and ‘Niagara’. The efficient screening system including inoculation method (spore suspension application and agar block inoculation), temperature (15, 20, and 25℃), and nutrient sources was developed and compared with the results obtained from other previous researches. As results, the factors temperature (20℃) and leaf age were included in the best model. Moreover, inoculating unwounded grapevine leaf of middle stage with spore suspension (10? spores?mL<SUP>-1</SUP>), prepared with 24 ㎎?mL<SUP>-1</SUP> of potato dextrose broth (PDB), showed clear differences among various grape varieties. After inoculation the vines maintained in saturated humidity at 20℃ showed different levels of resistance to gray mold among various grape cultivars. This screening system may be very useful for the precise evaluation of the resistance to gray mold by pathogen inoculation in the grape breeding programs.

분체제조와 그 가공기술의 발전으로 가연성 분진을 이용하는 미분화 공정이 증가하였다. 이로 인해 분진폭발 사고 가능성이 높아지고 있지만, 현 제도에서는 가연성 분진을 제외한 인화성 고체만이 규정에 의해 관리되고 있다. 이러한 관리 구조는 GHS제도가 도입되는 과정에서 만들어졌으며, 이로 인해 기존의 가연성 분진 관련 규정이 인화성 고체로 개정되었다. 인화성 고체의 판정기준을 만족하 는 가연성 분진은 극히 일부이기 때문에 가연성 분진이 관리의 사각지대에 놓이게 되었다. 이에 따라 가연성 분진 취급 사업장에 대한 관리의 필요성과 법적기준 강화 요구가 지속적으로 제기되고 있으며, 이러한 요구를 충족시키기 위해서는 관리가 필요한 가연성 분진을 도출하고 관리기준을 마련할 필요가 있다. 이 연구에서는 가연성 분진에 대한 정의 및 판별기준을 명확히 하고 관리가 필요한 대상을 도출함으로써 가연성 분진으로 인한 사고예방을 위한 관리기준을 제시하고자 한다. The development of powder manufacturing and processing technology has increased pulverization processes for combustible dusts. This led to the enhanced probability of dust explosion, but the current safety management system in Korea is only concerned with flammable solids, excluding combustible dusts. Such management structure was created by the introduction of the GHS system, followed by the revision of the regulations on combustible dusts to those on flammable solids. Since only a small number of combustible dusts are classified as flammable solids under the current criteria, most combustible dusts are under insufficient management. Thus, the continuing requests have been made for the management of combustible dust facilities and more stringent legal standards. This study suggested the improved legal standards for accident prevention by clarifying the definition and determination criteria for combustible dusts and identifying the items to be managed.

The Impact of Cortical Cerebral Microinfarcts on Functional Outcomes in Patients With Ischemic Stroke

Ham Jeong A,Jeong Yoon Jeong,Ma Min Kyeong,Moon Hyun Im 대한뇌신경재활학회 2022 뇌신경재활 Vol.15 No.3

The present study examined cortical cerebral microinfarcts (CMIs) on a 3T magnetic resonance imaging and investigated the impact of CMIs on the comprehensive functional outcomes during the post-stroke rehabilitation period. Patients with acute phase of first- ever ischemic stroke were retrospectively recruited (n = 62) and divided into 2 groups with and without CMIs. Clinical parameters including age, sex, stroke lesion laterality, location, the National Institutes of Health Stroke Scale score, as well as histor y of hypertension, dyslipidemia, diabetes mellitus, and smoking were obtained. Functional outcomes were assessed twice at baseline and one month later with the Korean version of the Mini- Mental State Examination, the Berg balance scale (BBS), and the functional independence measure. Partial correlation and multiple linear regression analyses were used to examine the relationship between the presence of CMIs and the change in functional outcomes. At least one CMI was reported in 27 patients, who were older (p = 0.043). The presence of CMIs was significantly associated with functional impairment in all 3 functional outcomes, after controlling for confounding factors (p < 0.05). CMIs might contribute to poor functional outcomes during the post-stroke rehabilitation period. These results suggest that CMIs should be considered when establishing rehabilitation treatment strategies or making a prognosis.

Bordeaux mixture made with each grade of lime and copper sulfate was tested general property and disease control value. Bordeaux mixture was made by composition of each grade of lime (95%, 80%) with each grade of copper sulfate(98.5%, 95%). Phytotoxicity was evaluated to Bordeaux mixture made with each grade of lime and copper sulfate, and then low grade copper sulfate (95%) was more severely in the grapevine leaf. Bordeaux mixture, made with each grade lime and copper sulfate, were tried to evaluate control effects of downy mildew in field. As a result, Bordeaux mixture (95% of lime and 98.5% of copper sulfate, 6-6) applied 5 times at late in June was showed more effective disease control value than any other trials of Bordeaux mixture. There was no difference in nutrient status of petiole each treatment. But fruit characteristics were shown more slightly improved quality.
