이 연구는 트레드밀 운동과 키네시오 테이핑의 효과에 따른 폐활량의 변화를 알아보기 위해 26명의 비흡연자가 참가하였으며 키네시오 테이핑을 적용하지 않은 그룹과 키네시오 테이핑을 적용한 두 그룹으로 무작위로 배정하고 각 군들을 주 3회 6주간의 트레드밀 훈련을 실시하였다. 실험 전과 후, 스파이로미터를 사용하여 키네시오 테이핑의 적용 따른 폐활량 변화 효과를 측정하였다. 이 연구의 결과를 종합해보면 키네시오 테이핑을 적용 그룹에서 적용하지 않은 그룹에 비해 FVC, FEV1에서 유의한 증가를 보였다. 이러한 결과는 건강한 성인에서 키네시오 테이핑을 적용한 경우 키네시오 테이핑을 적용하지 않고 트레드밀 운동을 한 경우보다 폐활량의 향상에 효과적이라고 생각되어진다. The purpose of this study was to investigate the variation of vital capacity(VC) according to the effects of kinesio taping with treadmill exercise. Twenty-six non-smokers were participated in this research and these subjects were randomly assigned into two groups. To measure the VC variation effects of kinesio taping, spirometer was used. The collected data were analyzed statistically by using a paired Mauchly test and repeated measure ANOVA. The results of this study were as follows; A group: treadmill with kinesio taping B group: treadmill without kinesio taping. Between A and B, there were significant differences. In the case of A group, there was 11.66% increase of VC, during 3 weeks experiment(p<.01). In the case of B group, there were significant differences, 3.35% increase of VC, during 3 weeks taping intervention(p<.01). After 6 weeks experiment, the improvement of VC shown a significant difference with intergroup (p<.05). From this result, it was revealed that treadmill exercise with kinesio taping was effective to improve VC to healthy adult than treadmill exercise without kinesio taping.

Objectives: This study aims to examine if a garbage dumping site has real and negative influence on the quality of life (QOL) for the nearby residents. The net effects of the residential distance from the garbage dumping site and from the garbage truck route were investigated for five domains of the QOL. Methods: Two hundred fifty seven Shin-dong Myeon residents, Chun-cheon Si, participated in a self-administrated survey. The Shin-dong Myeon garbage dumping site began operating in 1996. ANCOV A with generalized linear models and multiple regression analysis were performed. Results: Descriptive analyses show that a residence nearby a garbage dumping site is negatively associated with the physical and environmental domains of the QOL. The residential distance from the garbage truck route does not exert any significant effect on various domains of QOL, except for the environmental domain. On the multivariate analysis, the residents living near the garbage dumping site tended to have a significantly negative QOL in the physical and environmental domains. However, the distance from the garbage truck route did not show a significant nor substantial effect on the QOL. The demographic and socioeconomic control variables are associated with a number of the QOL domains, and their patterns are consistent with the general expectations. Conclusions: The results indicated that a garbage dumping site is considered to be an environmental hazard among the nearby residents according to the lower scores on the physical and environmental domains of the QOL. The findings from this study provide comprehensive understanding on the residents' QOL, and they may help politicians and policy makers make decisions for appropriate interventions.

The present study examined the effects of gait training with Additional weight in patients with chronic stroke. This study purposed to propose the effectiveness through comparative analysis of the effects of gait training with additional weight and gait training with non-additional weight on static balance and dynamic balance in patients with chronic stroke. The study was conducted at a hospital in Kyoung-ki do and the subjects were divided randomly into two groups: additional weight group(n =12), non-additional weight group(n =8). Both of groups received general physical therapy for 30min in 1 session, 5 sessions per a week during six months. Experimental group practiced gait training with additional weight for 20 min a day, 3 days per a week during 6 months and control group practised gait training with non- additional weight for 20min a day, 3 days per a week during 6 month. Static balance and dynamic balance were tested and analysed before and after the 6 weeks gait training, and the result were as follows. Static balance and dynamic balance is increased significantly in both of groups except for mediolateral sway(p < .05). the result of additioanl weight group showed more significant increase than the result of non-additional weight group (p < .05). According to the result of this study, as gait training with additional weight improves dynamic balance in patients with chronic stroke, this gait training method is effective and suitable for patients with chronic stroke to increase the ability of functional performance. 본 연구는 만성 뇌졸중 환자 20명을 대상으로 부하자극을 이용한 보행훈련이 만성 뇌졸중 환자의 정적균형 및 동적균형에 미치는 효과를 규명하고자 부하자극보행군 12명과 무부하자극보행군 8명으로 나누어 시행하였다. 부하자극보행군과 무부하자극보행군 모두 동일하게 1회 30분씩 주 5회 일반적 물리치료를 시행하였으며, 부하자극보행군에게 부하자극을 적용한 보행훈련을 1회 20분, 주 3회 실시하였고, 무부하자극보행군에게 부하자극을 적용하지 않은 보행훈련을 1회 20분, 주 3회 실시하였다. 훈련은 6주간 시행되었고 훈련 전ㆍ후에 정적균형과 동적균형을 측정하였으며 다음과 같은 결과를 얻었다. 부하자극보행군은 정적균형은 훈련 전보다 훈련 후에 유의하게 증가하였고(p < .05), 무부하자극보행군은 좌우동요를 제외하고 훈련 전보다 훈련 후에 유의하게 증가하였다(p < .05), 두 군의 전후 변화량의 유의한 차이를 보이지 않았다. 두 군 모두 동적균형은 훈련 전보다 훈련 후에 유의하게 증가하였고(p < .05), 부하자극보행군은 무부하자극보행군에 비해 유의한 증가를 보였다(p < .05). 위의 결과를 바탕으로, 부하자극을 적용한 보행훈련이 만성 뇌졸중 환자의 동적균형능력을 향상시키는 운동방법으로 뇌졸중 환자의 보행 재활에 활용할 수 있을 것으로 생각한다. 또한 정적균형을 향상시키는 방법으로는 적절하지 못하다고 생각한다.

Teeth have many characteristics compared to any other part of human body for the individual identification and strong resistance against external environment. So teeth is the major informant of dental identification in mass disasters. A dental inspector who accomplish dental identification should carefully observe the characteristics of teeth such as missing tooth, impacted tooth, supernumerary tooth, anatomical abnormality, dental caries, residual root rest, servre attrition, cervical abrasion, distinction of primary and permanent tooth, filling material, type and cavity, material and type of prosthesis, orthodontic appliance and information of dentition. There are enormous forensic odontological data of the victims in mass disasters. Such data has to be collected, selected and compared systematically antemortem and postmortem data of the victims by using computer and dental identification software. Using this kind of method, it is highly expected that dental identification can be more efficient than any other forensic identification.

The purpose of this study was to investigate the effect of knee exercises on the onset times of vastus medialis oblique muscle (VMO) and vastus lateralis muscle (VL) and in healthy subjects. Fifteen subjects (7 men, 8 women) in a mean age of 25.4 years participated in the study. Electromyographic (EMG) signals were recorded from the VMO and VL under four exercises. Knee exercises consisted of open kinematic terminal knee extension, straight leg raising, isometric hip adduction exercise, and closed kinematic terminal knee extension. No significant differences were found in the onset times of EMG activities of VMO and VL in the four exercises. There were also no significant differences among the exercises. These results coincided with previous studies that found no difference between onset of VMO and VL. However, it is difficult to say that there is no difference between onset of VMO and VL in healthy subjects. To confirm this results, further researches that follow same onset determination metod and exercises are needed. Not only is the study of onset time of muscle needed, but also the studies of the amount of activation and the rate of increase of muscle activation are needed.

석재 및 골재를 생산하는 석산사업장은 노천에서의 공정으로 발파, 파쇄, 선별, 운반과정에서, 석가공업체는 절삭 및 가공공정에서 주요한 공해요인으로서 분진이 발생한다. 국내에 분포하는 석·골재업체 중 석산에서 발생하는 분진의 평균농도가 약 3배 이상 높게 나타나며, 작업장의 위치별로는 발파를 위한 천공작업장 부근과 석판재를 절삭하는 갱쏘 작업장 부근에서 가장 높은 부유분진의 농도를 보였다. 채취한 강하 분진시료의 참비중은 전체적으로 2.46~2.72의 범위를 나타내었으며, 평균 입도는 11.6~116 ㎛의 범위를 보였다. 강하분진의 pH는 전체적으로 7.28~9.45의 범위값을 보여 약 알카리성 특징을 나타내었었고, 작열감량(loss on ignition; LOI)은 0.28~6.24 wt%의 범위를 보였으며, 강하분진의 화학조성은 광물조성에서와 같이 대상암석돌의 일반적인 화학조성과 유사한 특성을 나타내었다. 석산에서 부유분진이 대기로 확산되는 것을 억제하기 위하여는 분진의 발생을 최소화 할 수 있는 발파 설계법을 도입하고, 분진의 배출 방향을 통제하여 배출구 부근에서 집진장치나 방진망을 설치하면 효과가 있을 것이다. 석·골재 파쇄, 석가공, 운반 등 전 관정에서 분진의 발생과 확산을 억제하기 위하여 적절한 살수, 분진발생지점에서의 집진, 확산경로에 방진망의 설치 및 운반과정에서 제 규정 준수는 분진이 대기로 확산되는 것을 상당량 억제할 수 있을 것이다. Particulate matters, major pollutants discharged from rock quarries and stone manufacturing plants producing stones and aggregates, are originated in the processes of outdoor blasting, crushing, separation and transportation, and indoor cutting and processing. The average concentration of airborne dust from rock quarries is about three times higher than that from stone manufacturing plants, and drilling sites at rock quarries and gang saw areas show the highest concentration of airborne dust, respectively. Samples of fallen dust whose mineralogical and chemical compositions are related to parent rocks have true specific gravity of 2.46 to 2.72, average grain size of 11.6 to 116 ㎛, pH of 7.28 to 9.45 and LOI of 0.28 to 6.24wt%. A controlled blasting method should be adopted and dust collectors or dustproof nets in the course of dust dispersion will be effective to reduce emission and dispersion of airborne dust from rock quarries. Appropriate water spray, dust collection at dust emission points, dustproof nets, and speed limit of transportation vehicles are helpful schemes to mitigate emission and dispersion of airborne dust discharged in the processes of crushing, processing, transportation and etc. from stone and aggregate industries.

Current composites are made with dimethacrylate monomers and silane-treated silica microfillers, either alone or with silane treated glass fillers. The main reasons for clinical failure of dental composites are secondary caries, wear and fracture. Most of practitioner want to get a composite which is more tougher under occlusal stress, less polymerization contraction, and better handling properties in application clinically. The aim of this study was to investigate the influence of resin matrix with various flows on the physical properties such as facture toughness and degree of conversion of the experimental resins. It was hypothesized that flexible or tough resin compoties can be designed by judicious choice of monomer comptosition Various flow resin matrices containing Bis-GMA, UDMA, and TEG-DMA were made by altering the proportion of the monomers. After the unfilled resins were light-cured for different light intensity. the fracture toughness(K_1c) was measured according to ASTM standard using the the single edge notched geometry, and degree of conversion(DC) was measured by FTIR. And experimental composites were formulated with variations in the proportion of silanated quartzz and strontium glass fillers as 60, 75, and 77wt%. Also, the physical properties of composites with various filler contents were evaluated as same manner. All resulting data were compared by ANOVA/Tukeys test at 0.05 level. The results were as follows; 1. The degree of conversion of high flow resin containing less Bis-GMA was higher than that of low flow unfilled resin. 2. While the degree of conversion of unfilled resin was increased according to light intensity for polymerization, there was no significant increase with moderate and high light intensity. Also, the fracture toughness was not increased by high light intensity 3. The fracture toughness was high in the flow unfilled resin containing higher contents of Bis-GMA. 4. There was a significant increase for fracture toughness and a tendency for degree of conversion to be reduced when the content of fillers was increased. 5. In the experimental composites, the flow of resin matrix did not affected on the fracture toughness, even, which was decreased as increase of viscosity. These results showed that the physical properties of a dental composite could be attributed to the flow of resin matrix with relative content of monomers. Specific combination of resin monomers should be designed to fulfill the needs of specific indication for use.

Objective: To estimate the effects of bracket material type on enamel decalcification during orthodontic treatment, this study analyzed the adhesion level of mutans streptococci (MS) to orthodontic bracket materials in vivo. Methods: Three different types of orthodontic bracket materials were used: stainless steel, monocrystalline sapphire, and polycrystalline alumina. A balanced complete block design was used to exclude the effect of positional variation of bracket materials in the oral cavity. Three types of plastic individual trays were made and one subject placed the tray in the mouth for 12 hours. Then, the attached bacteria were isolated and incubated on a mitis salivarius media containing bacitracin for 48 hours. Finally, the number of colony forming units of MS was counted. The experiments were independently performed 5 times with each of the 3 trays, resulting in a total of 15 times. Mixed model ANOVA was used to compare the adhesion amount of MS. Results: There was no difference in colony forming units among the bracket materials irrespective of jaw and tooth position. Conclusions: This study suggested that the result of quantitative analysis of MS adhesion to various orthodontic bracket materials in vivo may differ from that of the condition in vitro. 법랑질 탈회는 교정 치료 중에 발생하는 대표적인 부작용으로서 특히 교정용 브라켓에 대한 세균 부착이 그 원인이 될 수 있다. 본 연구의 목적은 서로 다른 표면 특성을 가진 세 종류의 브라켓을 구강 내 장착했을 때 각 재료의 표면에 대한 mutans streptococci 부착 정도를 측정하여 브라켓 재료에 따른 법랑질 탈회 및 치아 우식 발생 가능성을 분석하는 것이었다. 상하악 및 치아 부위별 mutans streptococci 부착 정도의 차이를 배제하고 브라켓 원재료에 따른 차이만을 검출하기 위하여 균형완전블록 실험계획을 설계하였다. 피실험자인 30세 여성의 구강 내에 장착할 수 있는 tooth positioner 형태로 3세트의 플라스틱 맞춤 트레이를 제작하였으며, 이 트레이에 직육면체의 형태(4 x 3 x 2 mm)로 제작한 stainless steel, monocrystalline sapphire, polycrystalline alumina 조각을 세트마다 서로 다른 순서로 전치부와 구치부 순면에 부착하였다. 이렇게 제작된 3종류의 실험장치를 12시간 동안 피실험자의 구강 내에 장착한 후, 각 브라켓 재료 표면에 형성된 치태를 채취하여 bacitracin이 포함된 mitis salivarius배지에서 48시간 배양 후 colony counting을 통해 그 표면에 부착된 mutans streptococci 양을 비교하였다. 이와 같은 방법으로 3세트의 실험장치에 대해서 각각 5회씩 총 15회의 실험을 시행하였다. 그 결과 상하악 및 치아 부위별 및 브라켓 재료별 세균 부착 정도는 모두 유의한 차이를 보이지 않았다. 결론적으로 본 연구의 결과 in vivo condition에서 브라켓 재료의 차이는 mutans streptococci 부착에 영향을 미치지 못하는 것으로 보였다.

We selected at random 30 geriatric patients who had received operation under the general anesthesia with endotracheal intubation. The patients were divided into 3 groups. Group 1 (control) had received endotracheal intubation without diazepam and lidocaine. Group 2 had received endotracheal intubation with diazepam. Group 3 had received endotracheal intubation with lidocaine. The changes of arterial blood pressure and pulse rate, and the appearance of arrhythmia were compared in each group. The results were as follows : 1. The increase of blood pressure and heart rate were less in group 2, 3 than the control group which showed significant increase of blood pressure and heart rate with endotracheal intubation. 2. The incidence of arrhythmias with endotracheal intubation was less in group 2(20%), group 3(50%) than the control group(80%). 3. The electrocardiographic change in the group 2 and 3 were not significant compared to group 1(control).
