Purpose: To evaluate changes in corneal keratometry, high-order aberrations (HOAs), and anterior chamber parameters after trabeculectomy using Pentacam<sup>® (Oculus Inc., Dutenhofen, Germany). Methods: Forty eyes of 40 patients who underwent limbal-based trabeculectomy or fornix-based trabeculectomy between July 2011 and May 2012 were retrospectively reviewed. Intraocular pressure (IOP), corneal keratometry, central corneal thickness, anterior chamber depth, anterior chamber volume, and HOAs were measured using Pentacam<sup>® preoperatively and at 3 months postoperatively. Results: The mean age of patients who underwent trabeculectomy was 58.26 ± 16.28 years. IOP showed significant decrease after surgery in both groups compared to preoperative values (<em>p</em> < 0.05). There were no significant differences in corneal keratometry, anterior chamber depth, anterior chamber volume, central corneal thickness, total root mean square (RMS), trefoil, and coma after surgery (<em>p</em> > 0.05). Conclusions: Postoperative corneal keratometry and anterior chamber parameters did not change significantly compared to preoperative values in glaucoma patients after performing trabeculectomy. Most HOAs that affected quality of vision were not changed in the limbal-based trabeculectomy or fornix-based trabeculectomy. J Korean Ophthalmol Soc 2014;55(5):662-668

The purpose of this study was to test the difference of sitting balance control between a normal group and a group of patients with low back pain when their eyes were opened or closed. The 30 subjects of the control group had been chosen from healthy individuals who fit into the pre-designed criteria, and the 30 subjects of the experimental group were composed of the patients with LBP who had their treatment from S hospital from september 1, 2002, to October 30, 2002, and the subjects were measured by static balance test by using a balance performance monitor(BPM). Static balance test was done twice for each subject with his or her eyes opened and closed. Collected data were statistically analyzed by SPSS/PC using unpaired T-Test, Pained T-Test and multiple regression. The results were as follows: 1. In static balance test, normal group did not show statistical significance in sway angle(Anterior, Posterior, left and Right), sway path, sway area and maximal sway velocity, but showed statistical significance in mean balance with eyes opened and eyes dosed(P<.05) 2. In static balance test, LBP group did not show statistical significance in sway angle(Anterior, Posterior, left and Right), mean balance, sway path, sway area and maximal sway velocity with eyes opened and eyes dosed 3. With eyes opened, the comparison between the normal group and the LBP group showed statistical significance in sway angle(Anterior, Posterior, left and Right), mean valance, sway path, sway area and maximal sway velocity(p<.05). With eyes closed, normal group and LBP group did not show statistical significance in sway angle(Anterior and Right), sway area, but showed statistical significance in sway angle(Posterior and Left), mean balance, sway path, sway area and maximal sway velocity(p<.05) In conclusion, there was a significant difference in static sitting balance between normal group and LBP patients group. For future studies, I strongly suggest that researches be done on the treatment with LBP by predicting changes of postures and manipulating them.

The effects of electroacupuncture(EA) on blood concentration of endocrine substances were investigated in 6 horses. Three acupuncture points ; Guan Yuan Shu(BL-26), Wei Shu(BL-21) and Da Chang Shu(BL-25) were stimulated for 20 minutes by EA at separate occasions under varying condition ; 2V-1Hz, 2V-5Hz, 2V-30Hz, 4V-1Hz, 4V-5Hz and 4V-30Hz. Plasma levels of adrenocorticotropic hormone(ACTH), ${\beta}$-endorphin, epinephrine, norepinephrine and serum levels of gastrin were analysed. Blood samplings were carried out before, 0, 20 and 40 minutes after the EA stimulation. The serum gastrin levels were increased by 2V-5Hz stimulation on the Wei Shu. Plasma ACTH levels were decreased by 2V-1Hz stimulation on the Wei Shu, but largely increased by 4V-30Hz stimulation on the Guan Yuan Shu. Plasma ${\beta}$-endorphin levels were slightly increased or decreased by 2V-1Hz stimulation, but largely increased by 4V-30Hz stimulation on the Guan Yuan Shu. Plasma levels of epinephrine and norepinephrine were not so much changed by 2V-1Hz or 5Hz stimulation, but tended to increase by 4V-30Hz stimulation on Guan Yuan Shu. These results suggest that the low voltage-low frequence EA stimulation increased blood concentration of gastrin, but decreased ACTH, ${\beta}$-endorphin, epinephrine and norepinephrine, whereas high voltage-high frequence EA stimulation induced opposite results. Accordingly, there appears to be a close relationship between the changes of gastrointestinal motility and the changes of blood concentration of endocrine substances by EA stimulation.

The effects of electroacupuncture(EA) on gastrointestinal motility were investigated in 6 horses. Three acupuncture points ; Guan Yuan Shu(BL-26), Wei Shu(BL-21) and Da Chang Shu(BL-25) were stimulated for 20 minutes by EA at separate occasions under varying condition ; 2V-1Hz, 2V-5Hz, 2V-30Hz, 4V-1Hz, 4V-5Hz and 4V-30Hz. Myoelectric activity of stomach and cecum was monitored to investigate the gastrointestinal motility. Electromyogram(EMG) recordings were carried out before, 0, 20 minutes after and 40 minutes after the EA stimulation. EMG bipolar electrode was surgically implanted in seromuscular layer of greater curvature in the stomach and between medial band and ventral band in the cecum. The EA stimulation and monitoring were not commenced until 15 days after electrode implantation. The EA stimulation of Wei Shu influenced on stomach motility and that of Da Chang Shu on, cecum motility. However, the EA stimulation of Guan Yuan Shu influenced on both the stomach and the cecum motility. The myoelectrical spike burst amplitude of the stomach and the cecum was significantly(p<0.05) increased by 2V-1Hz stimulation, but the myoelectrical spike burst frequence of the stomach and the cecum was significantly decreased by 2V-30Hz or 4V-30Hz stimulation. The myoelectrical spike burst duration of the stomach and the cecum was significantly lengthened by 4V-30Hz and 2V or 4V-30Hz stimulation, respectively.

김병선,최희인,Kim Byungsun,Choi Hee-In 한국임상수의학회 1991 한국임상수의학회지 Vol.8 No.1

The effects of intra-articula. sodium hyaluronate(SH) and polysulfated glycosaminoglycan(PSGAG) on degenerative joint disease of the carpus were compared each other In 20 racehorses. Ten horses were dosed with intra-articula. injection of 20mg SH(2 times/2 weeks interval) and ten horses were dosed with intra-articular injection of 250mg of PSGAG(4 times/1 week into.val). Synovial fluid analysis and clinical examination were made to evaluate the effects of the drugs on degenerative joint disease at before injection and 2 weeks after the last injection, respectively. Appearance and mucinous precipitate quality oi synovial fluids of the group injected with 58 and PSGAG were improved by 40~50% and 60~80%, respectively. The chemical values of alkaline phosphatase, lactic dehydrogenase, aspartate aminotransferase, total protein, A/G ratio and glucose of synovial fluid in the group injected with PSGAG were more clearly returned to the normal values than those of the group injected with SH. Relative viscosity and total white blood cells of synovial fluid were returned to the normal walues after the treatments in both groups. Clinical symptoms(swelling, heat and pain on carpal joint, and lameness) of the horses in the group injected with SH and PSGAG were disappeard by 56~67% and 67~80%, respectivelty. Conclusively, the PSGAG was superior to SH in the effects on treatment of the degenerative joint disease in the horses.

디지털 트윈 국토는 한국판 뉴딜 정책의 일환으로 추진 중인 국가 프로젝트이나 이에 대한 표준이나 기술 기준 등은 마련되어 있지 않은 상태이다. 이러한 배경에서 본 연구는 디지털 트윈 국토의 상호 운용성 확보를 위한 공간정보 표준 기반의 참조 모델과 데이터 모델 구축 방안을 제시하는데 목적이 있다. 이를 위해 디지털 트윈에 관한 국제 표준화 동향을 검토하고 주요 시사점을 도출하였다. 그리고 디지털 트윈 국토에 대한 정의, 도메인별 특징을 도출하는 등 디지털 트윈 국토에 대한 개념을 정립하였다. 이러한 개념을 바탕으로 RM-ODP를 이용한 디지털 트윈 국토 참조 모델 구축 방안과 3단계 디지털 트윈 국토 데이터 모델 체계를 제안하였다. 또한 데이터 모델의 효율적 관리를 위한 모델 레지스트리 구축 방안을 제안하였다. 본 연구에서 제안한 정책 방안은 향후 디지털 트윈 국토 표준 체계 구축의 방향성을 확립하는데 기여할 것으로 판단된다. Digital Twin for Land(DTL) is one of the national work projects in the Korean New Deal but there aren't still any standards and technical guides which would need to construct the DTL. This study presents the policies to develop reference model and data model based on geo-spatial information standards to ensure interoperability for the DTL. In this paper, we first extract the implications through reviewing definitions of Digital Twin used in various literatures and international standardization trends on Digital Twin. In addition, this study attempts to conceptualize the DTL through various ways such as defining the DTL and characterizing DTL domains. Finally, we propose three policies on the standardization of the DTS: (1) DTS reference model by using RM-ODP, (2) three-steps hierarchical data models, and (3) model registry to manage the data models efficiently. The proposed policies of the study would contribute to establish a way for DTS's standards development over the coming years.
