This study aims to investigate the effect of trunk muscle strengthening exercises on balance performance of sitting posture and muscle tone, targeting the children with spastic diplegic cerebral palsy. 16 children with spastic diplegic cerebral palsy in IV phase of GMFCS were sampled at random and the tests were conducted for 6 weeks, 3 times per week. For experimental groups, only trunk muscle strengthening exercises were conducted and for control groups, only basic physical therapy was conducted. The trunk muscle strengthening exercise consisted of 2 exercises to strengthen abdominal muscles and back muscles. BPM(Balance Performance Monitor) was used to measure balance performance and MMAS(Modified Modified Ashworth Scale) was used to measure muscle tone. As a result, the changes of sitting balance performance in experimental groups and control groups show significant difference in the changes of sway path and sway velocity(p<.05), the comparison of changes in sitting balance performance in between experimental groups and control groups show significant difference in the changes of sway path and sway velocity(p<.05). Knee flexor muscles and hip adductor muscles in both groups show no significant difference in changes of the muscle tone(p>.05). Therefore, the balance performance in both experimental groups and control groups was improved. However, the experimental group had more significant improvement in balance performance and no change in muscle tone was detected in both groups. Thus, these findings show trunk muscle strengthening exercises are effective in improving the balance performance of sitting posture for the children with spastic diplegic cerebral palsy without changing muscle tone.

The study was performed to determine the impact of the gastrocnemius taping with balance training on spasticity and balance ability of the ankle joint. A total of 25 stroke subjects were divided into two groups: a taping with balance training (n=14), a sham taping with balance training (n=11). Spasticity assesment was scored by modified ashworth scale. Balance ability assesment was performed by functional reach test (FRT), the timed up & go test (TUG). The stability index (SI), the left-right weight distribution (left-right WD), the toe-heel weight distribution (toe-heel WD) were analyzed in the eyes open conditions(EO) and eyes closed conditions(EC) conditions using by the Tetrax interactive balance system. The experimental group showed a significant improvement in SI, left-right WD and toe-heel WD in the EO and EC, MAS, FRT, TUG. In comparison between the groups, a significant improvement was detected in FRT, TUG, SI and left-right WD in the EO, and left-right WD and toe-heel WD in the EC. It was found out that a short period of balance training with taping is effective on spasticity and balance ability in stroke patients. Therefore, any stroke patient without skin damage is encouraged to use the gastrocnemius taping for balance rehabilitation.

This study was conducted to investigate changes in activities of daily living (ADLs) according to the Gross Motor Function Classification System (GMFCS) after one year of physical and occupational therapy and to compare the responsiveness of ADL tools. A total of 48 children with spastic cerebral palsy participated in the study. The GMFCS, Functional Independence Measure for Children (WeeFIM), and Pediatric Evaluation of Disability Inventory (PEDI) were measured. The results showed that the GMFCS was significantly correlated with the PEDI (p<0.05), while there was a significant difference in the change of ADLs measured by the PEDI, but not the WeeFIM. There was a significant difference in the changes in ADLs according to the GMFCS, and the change in ADLs in the high functional level group was significantly higher than in the low functional level group (p<0.05). After physical and occupational therapy, the degree of improvement of ADLs varied according to the GMFCS, but seemed to be improved in a clinically meaningfully way. The PEDI is sensitive to changes in ADLs, so it may be used widely in clinical practice.

This study was carried out to investigate the effects of planting density, time and frequency of pinching on growth and yield of Lycium chinese Miller cultivated in vinyl house. This experiment was conducted at the experimental field of Cheong-yang Agriculture High School, Cheong-yang, Chung-nam province, in 1997 to 1998. The number of flowers, fruit setting number and dry weight of fruits per branch were increased as the spacings were wider, but the fruit yield per unit area was decreased up to the narrowest spacing plot of $60\;{\times}\;20cm$. The good results of growth status and fruit yield was obtained at the early pinching in May 5. As the more frequent pinching were treated, the more number of flowers and fruits per branch were produced, showing increase of fresh and dry yield, because of much more branches per plot.

연축성 발성장애(spasmodic dysphonia)는 아직까지 그 원인을 정확히 밝혀내지 못하고 있는 만성적인 발성장애로 과거에는 경직성 발성장애(spastic dysphonia)로 불리던 질환이다. 연축성 발성장애는 두 종류 즉, 내전형(adductor)과 외전형(abductor)으로 나누어지며 이중 내전형이 대부분이다. 외전형 연축성 발성장애는 발성도중에 성대가 갑자기 불수의적으로 외전되면서 음성이 중단되므로 원활히 대화하기가 힘든 질환이다. 이러한 질환은 국소적 근긴장이상(fecal dystonia)의 일종이다. 현재까지 연축성 발성장애의 치료법으로 사용되고 있는 것으로는 언어치료, botulium 독소주입술, 편측반회후두신경절 단술, 반회후두신경분쇄술, 상후두신경절단술, 갑상연골성형술, implantable stimulator 등이 있다. 연축성 발성장애 환자에 $Botox^{circledR}$ 주입에 관한 보고는 주로 내전형에 대해서만 보고되고 있으며 외전형에 대하여 보고된 예는 매우 적다.

To know the extension effect of storage temperature on the pre-rigor period of plaice, Paratichthys olivaceus muscle, the relationship between early changes after death and temperature dependency was studied. Killed plaices instantly with spiking at the brain were stored at $-3^{\circ}C,\;0^{\circ}C,\;5^{\circ}C\;and\;10^{\circ}$ used in studying the changes in rigor Index, ATP and its related compounds, lactate contents and K-value. The most shortest onset time of rigor-mortis and full rigor was revealed in the sample stored at $-3^{\circ}C$ among the all samples, where rigor-mortis began at 4hrs after spiking and maximum tension was attained after 28hrs. However, in case of fresh plaice muscle stored at $10^{\circ}C$, the onset of rigor-mortis and full rigor were retarded to 14hrs and 52hrs after spiking. ATP in sample stored at $5^{\circ}C\;and\;10^{\circ}C$ were decomposed slowly than sample at $0^{\circ}C\;-3^{\circ}C $ and within 35hrs storage. The fastest rate and the maximum content of lactate accumulation were showed in sample stored at $-3^{\circ}$ among the all samples. The correlation coefficient(r) between the rate of rigor mortis and ATP breakdown, rigor mortis and lactate accumulation, and ATP breakdown and lactate accumulation were -0.981946, 0.965044, and -0.964728, respectively. Freshness of $-3^{\circ}C$ stored samples was maintained for the longest time compared with other stored samples. The times reached around $20\%$ of K-value were 240hrs for samples stored at $-3^{\circ}C,\;96hrs\;for\;0^{\circ}C\;samples,\;71hrs\;for\;5^{\circ}C\;samples,\;and\;22hrs\;for\;10^{\circ}C$ samples. Samples stored at $-3^{\circ}C,\;and\;0^{\circ}C$ were showed higher temperature dependency on rate of rigor-mortis, ATP breakdown, and lactate accumulation than $5^{\circ}C\;and\;10^{\circ}C$ stored samples, but those samples have a lower temperature dependency on K-value.

1974년에 서울지하철 1호선이 개통된 이래, 지하철은 대도시의 교통난 해소에 중추적인 역할을 하고 있으며, 현재에도 많은 지하철건설이 계획되고 있다. 그러나 지하철 건설에 소요되는 막대한 예산과 공공교통이라는 명분에 의한 이용요금의 경직성 때문에 발생되는 운영비용의 적자로 인해서, 보다 경제적이고 효율적인 새로운 도시철도의 도입을 고려하게 되었으며 그 대안으로 경량전철시스템 도입이 적극 추진되기에 이르렀다. (중략)
