The purpose of this study was to develop a practical and applicable rating scale for family day care based on the actual state of facilities and the opinions of child care teachers and professionals. This study was developed as following procedures: First, this procedure was based on both literature review and survey. The subjects of survey were 36 family day care directors and 14 college professors who specialize in early childhood care & education in Pusan. Questionnaire containing 69 items in 10 sub-areas of 4 major areas, "Physical Environment", "Propam for Children", "Safety, Nutrition, Health, and Sanitation" and "Management and Administration", was originally developed by the researchers of this study. Based on responses of the subjects, 50 items were selected. Second, this Rating Scale was consisted of 50 items with 5-point rating selected for the study. 50 directors responded the scale voluntarily. Third, the information about statistical result of this rating scale was gathered and reported. Means and standard deviations were calculated in 10 sub-areas and 4 major areas. Correlation coefficient and t-test were used for item analysis. Cronbach α was used for item reliability. The results were as follows: First, the scores of self-evaluation of family day care directors were ranged from 2.28 to 4.68 and the mean of total rating score was 3.54. Second, except 5 items, the results of item analysis indicated that most items of Family Day Care Ratintg Scale were fairly good. Third, for reliability, conbach α of family Day Care Rating Scale was between .84~.90. Futher Family Day Care Rating Scale would be utilized by individual directors of family day care center to do self-evaluation, by supervisors to collect information and guide each family day care center for the improvement, by the goverment to use in planning child care policies.

지가상승이 통화량 증가에 따른 인플레이션의 효과와 마찬가지로 소비나 저축에 영향을 줄 수 있는 가능성이 있음에도 불구하고 이에 대해 소득분배구조의 악화, 노동의욕의 감퇴, 비용증가에 따른 경쟁력 약화 등의 악영향을 준다는 단편적인 분석은 많지만 소비나 저축에 미친 영향을 실증분석한 예는 흔치 않은 실정이다. 80년대 후반으로 오면서 지가상승과 소비증가와의 관계를 실증적으로 분석한 예가 몇 있을 뿐이다. 본 논문은 한국의 저축동원을 중심으로 지가상승의 영향을 실증적으로 분석하고, 이를 근거로 향후 지가정책에 있어서의 시사를 도출하고자 하였는데 그 결과는 지가상승이 국내저축에 정의 영향을 준 것으로 나타났다. 토지가격의 상승이 소비로 이러지기 위해서는 사회적 분위기나 정부의 소비억제 정책에도 영향을 받고 시기적으로 다를 수 있다. 한국의 경우 국민들의 토지에 대한 선호도가 높아 토지의 구입이나 임차를 위해, 또 기업들의 토지의 소유정도가 높음을 감안한다면 이러한 지가상승은 기업의 재무구조를 개선시켰을 뿐만 아니라 사내유보증가 등에 따라 국내저축에 기여했다고 볼 수 있다. 그리고 80년대 후반 이러한 지가상승의 영향은 과소비 풍조가 만연되면서 저축으로 이어지기 보다는 오히려 소비를 증가시켜 80년대 후반 국민총저축의 감소를 초래했다고 보는 것이 타당할 것이다. 여기서 앞으로 지가상승과 같은 자산인플레이션으로는 유일한 정의 효과라 할 수 있는 저축의 증대가 가능하지 않다는 시사를 얻을 수 있을 것이다.

The analysis of anthracite coal as fired basis and clinkers located on combustor, seal pot and cyclone to find out the reason why the bed materials agglomerated and resulted in clinkers were studied. It was one of the most serious problem in early period operating the Tonghae CFBC(Circulating Fluidized Bed Combustor). The proximate analysis, heat value analysis, ash fusion temperature analysis and size distribution analysis of coal & ash were studied using TGA, Bomb Calorimeter, Ash Fusibility Determination and Sieve Shaker. The chemical compositions and microstructure of raw material and clinker located on combustor, seal pot and cyclone were investigated by the scanning electron microscope(SEM) with an energy dispersive X-ray spectrometer(EDS), ICP-AES, X-ray diffractometer(XRD). The domestic anthracite coal had much fine size portion which could cause after burning. Furthermore domestic coal had higher ignition temperature and lower volatile matter portion than bituminous coal, which finally ended in low combustion velocity. So it is fundamental to lengthen the furnace residence time to reach complete combustion. And it is possible to use auxiliary fuel but its dependence is low for CFBS because combustion temperature is at around 800~850℃, which range is very lower than general fine size coal combustion type. Fine size coal could do after burning, so it could cause temperature rising at combustor upper region and clinker formation by means of fouling. The short residence time of fine size coal in furnace can bring out high content of unburned carbon in fly ash, so it is necessary to reduce the fine size coal content. Assembling the result of chemical composition analysis, crystal structure analysis and EDS analysis of clinker, we could conclude that calcium in limestone and iron in bed material did the main effect in agglomeration.

This study was designed to identify the effects of walking conditions (normal walking vs. toe-walking) on electromyographic (EMG) activity of gastrocnemius, tibialis anterior, and soleus muscle. Seven healthy adult males participated in this study. The exclusion criteria were orthopedic or neurologic disease, congenital anomaly or acquired deformity, or pain in low back or lower extremities. The maximal voluntary isometric contraction for each muscle was used for the reference contraction, and EMG activity of each muscle during normal walking and toe-walking was expressed as a percentage of reference contraction. The gait cycle was determined with two foot switches, and gait was normalized as 100% gait cycle for each condition. The maximal values of EMG activity in terminal stance (30~50% of gait cycle) of each condition were compared for data analysis. No significant differences were found in EMG activity of the tibialis anterior and soleus (p<.05), whereas significant decrement was found in EMG activity of gastrocnemius during toe-walking compared to normal walking (p<.05). There is a limitation to generalize the results of this study, because small number of subjects participated for this study and only EMG was used for data collection. The treatment methods should be developed to improve gait efficiency by substituting the weakened muscles secondary to upper motor neuron, or by strengthening the distal muscles in lower extremity.

李鎭澤,鄭眞宇 慶一大學校 1992 論文集 Vol.8 No.1

In order to give basic materoal date for the power training know relation between the load and the power, and random sampled to cluster. The result of analyzing the knee joint's extension were as follo. 1. The 1/5 of the maximum muscular strength is more faster than of that in time and speed when they bunder to the maximum muscular strength. But the case of 1/5 was less than cases of 1/3 or 1/2 in force energy and power(p<0.05) 2. The 1/3 of the maximum muscular strength is more faser than that in time and speed when they bunder to the maximum muscular. But the case of 1/3 was less then the case of 1/2 in force energy there is no meaning the difference of the power between each. 3. It was most powerful in the case of 1/2 or 1/3 of the maximum strength when they bunder to that than any other case.

본 연구는 관절염 유발시 일어나는 관절낭의 형태학적 변화를 조사하기위해 ljpopolysaccharide(LPS)주사로 인위적 관절낭 염증을 유발시킨 후 시간경과에 따른 윤활관절막과 섬유관절막의 형태 변화를 관찰하였다. BALB/C 암컷 생쥐 오른쪽 무릎관절낭에 LPS 300㎍/㎏를 주사한 후 3, 7 그리고 14일에 무릎관절을 얻었다. 무릎관절은 4주동안 EDTA용액에 탈회한 후 통상적 방법으로 paraffin에 포매하였다. 또한 윤활관절막의 미세구조변화는 embed812로 포매한 후 관찰하였다. LPS 주사후 관절연골 인접부위의 윤활관절막에서 시작된 세포과형성(hyperplasia)은 시간 경과후 전체 윤활관절막으로 확대되었다. 윤활관절막내의 미세구조의 변화로는 윤활포식세포(type 1)가 관절강내로의 많은 돌기(filopodia)를 내었고, 잘 발달된 과립형질내세망을 가지는 type 2 윤활분비세포의 숫적 증가가 보였다. 한편 LPS 주사후 섬유관절막에서 나타나는 형태학적 변화는 collagen fiber 생성에 의한 섬유화가 증가되며, 이러한 섬유화를 주도하는 섬유모세포의 이주증가파 관찰되었다. 또한 혈관 주위에서는 백혈구의 이주 증가가 나타났으며, 탈과립형(degranulated type) 비만세포가 많이 관찰되었다. 이상의 결과로 LPS 주사로 관절낭에서 염증이 유발되어 윤활관전막과 섬유관절막에서 형태학적 변화가 나타났다. 이러한 일련의 형태학적 변화는 발병초기 류마티스성 관절염에서 나타나는 병리학적 소건과 동일한 결과로서, 앞으로 진행될 치료제 개발과 유발기전에 관한 해석을 위한 in vivo 실험의 적절한 모델로 기여한 것으로 기대된다. Synovial joint of BALB/C mice were injeced with Lipopolysaccharide(LPS) were observed to investigate the morphological changes of synovial capsule caused by rheumatoid arthritis(RA). The RA on female Balb/c mice were induced by LPS injection, as dose of 300㎍/㎏, into synovial cavity of knee joint. And then these specimen were fixed in 10% neutral buffered formalin and were decalcificated in EDTA solution for 4 weeks. The hyperplasia of synovium were appeared in synovial membrane. The filopodia of phagocytic like synoviocyte(type Ⅰ synoviocyte) projected into synovial cavity and the number of fibroblast like synoviocyte(type Ⅱ synoviocyte) with well-developed endoplasmic reticulum were increased in synovium. In fibrous membrane, the fibrosis induced by synthesis of collagen fiber were enlarged to all fibrous membrane, and the number of fibroblast were increased. A great number of inflammation component cell as Iymphocyte and neutrophil leukocyte were infiltrated around capillary and the degranulate typed mast cell were increased. As results indicated that the hyperplasia of synovium induced by LPS, subsequently to cause the fibrosis, infiltration of imflammation component cell, and increase of degranulated type mast call as same as symptoms of RA.

이재용,정상택,김진구,이안수 한국스포츠심리학회 2002 한국스포츠심리학회지 Vol.13 No.3

장기적 과훈련은 경기력 저하는 물론 심리적으로도 부정적인 결과를 초래한다고 많은 연구들은 지적하고 있다. 이에 본 연구에서는 단기적 과훈련에 따른 고등학교 축구선수들의 기분 변화를 조사하여 코치나 감독에게 선수지도에 유용한 정보를 제공하기 위함이다. 이 실험에 참가한 피험자는 25명이 고등학교 축구선수로 평균 운동경력은 3년9개월이었다. 피험자들은 1시간 30분, 3 시간, 그리고 4 시간 30분 조건에서 훈련 전후 측정되어졌다. 각 조건에서 훈련 시 발생했을 피로를 회복시키기 위해 조건간 측정 간격을 48시간으로 하였다. 기분 변화를 측정하기 위해 McAuley와 Courneya(1994)가 만든 주관적 운동 경험 척도(Subjective Exercise Experiences Scale : SEES)를 사용했다. SEES는 (1) 긍정적 행복감(positive well-being), (2) 심리적 부정스트레스(psychological distress), (3) 피로(fatigue) 등 3가지 영역에 12가지 항목을 기초로 하여 만들어 졌다. 본 연구결과 평상시(3시간)보다 훈련 양을 증가시켜 훈련을 시켰을 때 선수들의 심리적 부정 스트레스와 피로가 증가되었고 긍정적인 행복감은 감소되는 것으로 나타났다. It is well documented that athletes who overtrained definitely experience performance decrements as well as negative training adaptations. Therefore, to improve athletic performance, athletes must be optimally trained. The purpose of this study was to determine the effects of overtraining on the psychological well-being, psychological distress and fatigue of high school soccer players. Twenty-five high school soccer players were participated in this study. Their ages ranged from 17 to 18, with a mean age of 17.2 years, and mean experience of 3 years and 9 months. All subjects participated in three different training session(1 hour 30 min, 3 hours, and 4 hours 30 min) in a row. The interval of each training session was two days. The Subjective Exercise Experiences Scale(SEES) was administrated to measure subjects' mood alteration before and after each training session. The results of this study indicated that subjects in the 4 hours and 30 min overtraining condition showed more increments in fatigue and psychological distress than the rest of two conditions. The results of this study also indicated that mood disturbance which may be a potential factor influencing performance increased significantly as the training load increased. Psychological responses to overtraining results in negative effects. The present study suggests that in order to improve athletic performance, coach should understand the negative effects of overtraining in terms of psychological functioning.
