Purpose: The purposes of this study were to develop the Korean version of the trunk impairment scale (K-TIS) and to examine reliability and responsiveness of the K-TIS in patients with stroke. Methods Subjects of the study were 51 stroke patients (mean age: 57.78 years) recruited from two stroke clinics. For the interrater and test-retest reliability, two raters measured the K-TIS two times using video clips with an interval of 2 weeks. For the responsiveness, intensive physical therapy training was provided to all participants 2 times a day for one month or three months depending on the onset of the stroke and the admission rules of the two clinics. Inter-rater reliability and test-retest reliability of the K-TIS three subscales (static sitting balance, dynamic sitting balance, and coordination) scores and total scores were examined using intra-correlation coefficient ($ICC_{3,1}$) and Pearson's correlation coefficient (r). To examine responsiveness, the minimally important difference (MID) was calculated with effect size. Results: Inter-rater reliability of the K-TIS subscales and total scores were all high (ICC3,1=0.920-0.983 and r=0.924-0.984). For the test-retest reliability, $ICC_{3,1}$=0.805-0.901 and r=0.806-0.903, and the MID for acute and post-acute as well as chronic stroke patients remained in the mean change range. Conclusion: It is suggested that the K-TIS might be used for clinical and research purposes as a standardized tool for stroke patients. In addition, it can also be useful in establishment of treatment goal(s) and planning treatment program(s) for patients with stroke.

In this paper, a realization of a real-time train information system(TIS) is discussed. The requirements of TIS which satisfy real-time constraints are analyzed in view of data transfer. For efficient data communication in TIS, a new network system is suggested and its real-time characteristics are analyzed and compared with the standard network system. A local unit is designed based on VMEbus system.

The aim of this study was to investigate correlations of the Trunk Control Test (TCT), Postural Assessment Scale for Stroke (PASS-TC), and Trunk Impairment Scale (TIS) and to compare the TCT, PASS-TC, TIS and its subscales in relation to balance, gait and functional performance ability after stroke. Sixty-two stroke patients attending a rehabilitation program participated in the study. Trunk control was measured with the use of TCT, PASS-TC, TIS balance (Berg Balance scale; BSS), gait ability (10 m walk test), functional performance ability (Tuned Up and Go Test TUG) and the mobility part of the Modified Barthel index (MBI), Fugl Meyer-Upper/Lower Extremity ($FM-U{\cdot}L/E$), The scatter-plot (correlation coefficient) was composed for the total scores of the TCT, PASS-TC, and TIS. The multiple regression analysis was performed to evaluate the impact of trunk control on balance, gait, and functional performance ability. Twenty eight participants (45.2%) and twenty participants (32.3%) obtained the maximum score on the TCT and PASS-TC respectively; no subject reached the maximum score on the Trunk Impairment Scale. There were significant correlations between the TIS and TCT (r=.38, p<.01), PASS-TC (r=.30, p<.05), TCT and PASS-TC (r=.59, p<.01). Stepwise multiple regression analysis showed that the BBS score (${\beta}=.420{\sim}.832$) had slightly more power in predicting trunk control than the $FM-U{\cdot}L/E$. TIS-dynamic sitting balance, TUG and the MBI-mobility part. This study 치early indicates that trunk control is still impaired in stroke patients. Measures of trunk control were significantly related with values of balance, gait and functional performance ability. The results imply that management of trunk rehabilitation after stroke should be emphasized.

PURPOSE: The purpose of this study was to compare sitting balance and coordination spastic cerebral palsy in children using the Korean version of Trunk Impairment Scale (K-TIS) as well as to provide basic data about effective postural control treatment for clinicians handling these two types. METHODS: The K-TIS was measured in 29 children diagnosed with diplegic and quadriplegic cerebral palsy (18 with diplegia and 11 with quadriplegia). The average and standard scores of the children's K-TIS subscales and items of the two groups were measured. The two groups' subscales and items were analyzed by using the Mann-Whitney U test. RESULTS: Static sitting balance, dynamic sitting balance, coordination, and total score for children with diplegia were statistically high (p<.05). For all items under static sitting balance, the score for children with diplegia was higher. The first differences in the repeated items of dynamic sitting balance and coordination area that rotates between the upper and lower body were presented. CONCLUSION: The difference in balance and coordination in sitting positions is exhibited in children with diplegia and quadriplegia. For children with spastic quadriplegia, treatments should focus on static sitting balance and coordination, together with a focus on dynamic sitting balance and coordination.

This paper addresses prospect of the technology for development of NxTIS (NeXt generation Transport Information System) that is targeted to shifting Korean public transit framework to railway-centered one. The Seoul metropolitan area has adopted the smart-card as a payment system for the public transportation since 2004. The transportation record can be used as quite useful information for better planning and operating of the railway system, particularly when the smart-card based payment system is extended to whole nation. This paper introduces technologies to develop Real OD DB and NxTIS, and presents road-map for them. A variety of benefits from the development of the system are estimated both in quantitative and qualitative. The Real OD DB based NxTIS will work to highly prospective for creating a novel value in the railway as a public transportation system.

다양한 분야의 요구에 따라 반사율이 99.995% 이상인 고반사 저손실 반사경의 제작이 가능해 지면서 반사경의 산란, 투과, 흡수 및 손실 등을 측정하는 여러 측정 방법들도 더불어 연구되어 왔다. 적용 분야에 따라 사용될 반사경의 특성이 결정되는데 그 중 중력파 측정 장치$^{(1)}$ , 광자 감쇠 분광기$^{(2)}$ 등의 분야에서는 투과, 산란 및 흡수가 모두 작은 저손실 반사경을 요구한다. 한편 링 레이저 자이로스코프의 경우 반사경의 산란이 곧 lock-in을 결정하여 성능을 제한하는 중요한 변수가 된다. 따라서 이 응용의 경우 반사경의 산란을 정확히 측정하는 일은 중요하며 위치에 따른 산란분포 정보를 알면 링 레이저 자이로스코프의 성능 예측과 개선이 더욱 쉬워진다. 산란을 측정하는 직접적인 방법에는 ARS(angle resolved scattering)과 TIS(total integrated scattering)이 있는데, 본 연구에서는 TIS 측정 장비를 반사경의 위치에 따른 산란분포까지 측정할 수 있도록 mapping 기능을 첨가하고 이온빔 스퍼터링에 의해 제작된 저산란 반사경을 측정하기 위해 높은 분해능을 갖도록 구성하였다. 반사경의 응용분야의 필요에 의해 45$^{\circ}$ 산란을 측정하였다.

Purpose: This study aimed to investigate the relationship between trunk control and pulmonary function and respiratory muscle strength in stroke patients. Methods: This study included 30 patients who had been clinically diagnosed with strokes, and trunk control abilities were measured using the trunk impairment scale (TIS). The subjects were classified into a group with high trunk control ability (TIS score ${\geq}20$) and a group with low trunk control ability (TIS score < 20). The patients' forced vital capacity (FVC), forced expiratory volume in one second (FEV1), peak expiratory flow (PEF), maximal inspiratory pressure (MIP), and maximal expiratory pressure (MEP) were measured. To compare the pulmonary function and respiratory muscle strength between the two groups, the measurement data were analyzed using an independent T-test, and the relationship between TIS and respiratory function was analyzed using a Pearson correlation. Results: The high trunk control ability group had significantly higher pulmonary function and respiratory muscle strength than the low trunk control ability group. Significant positive correlations were found between trunk control and FVC, FEV1, PEF, MIP, and MEP. Conclusions: This study demonstrated that trunk control affects pulmonary function and respiratory muscle strength in stroke patients.

For an efficient management and analysis of geological/geotechnical data obtained during site investigations or tunnel construction, Tunnel Information System(TIS) was developed in this study. TIS is running in CIS(Geographical Information System) which has a spatial data. TIS consists of two parts, the Tunnel Face Mapping System(FaceMap), to record a geological features by observations and measurements at the surface of the excavation, the Borehole Data Management System(BDMS), to store the different types of rock data related to boreholes. Using the database of collapsed tunnels, 20 in Korea and 84 in Europe and with an artificial neural network, an expert system was developed for inferring the tunnel collapse pattern and its volume. And by applying Geo-predict, the system developed, in tunnels under construction, observed data from the $\bigcirc$$\bigcirc$tunnl site was compared and analyzed.
