The upshoot and downshoot in Duane's retraction syndrome is believed to be related to a leash effect from the lateral rectus muscle. When the eye is rotated into the adducted position, the lateral rectus muscle slips over the globe, producing the up-and downshoot on adduction. The splitting of the ends of the lateral rectus into a Y configuration prevents the rotation of the globe up or down by stabilizing the muscle's position on the eye. Three patients with Duane's retraction syndrome demonstrated abnormal vertical movement on adduction and underwent a Y-splitting on the lateral rectus. In all patients, marked decrease in the up-and downshoot is noted after surgery.

Numerical analysis of the three dimensional turbulent flow field in a complex valve trim is carried out to confirm the possibility whether this simulation tool can be used as a design tool or not. The simulation of the incompressible flow in a glove valve is performed by using the commercial code. CFD-ACEA utilizes the finite volume approach as a discretization scheme, and the pressure-velocity coupling is made from SIMPLEC algorithm in it. Four flow cases of the control valve are investigated, and the valve flow coefficient for each case is compared with the experimental data. Simulation results show a good agreement with the experiments, and it is observed that the cavitation model improves the simulation results.

This paper examines and analyzes improvement of structure of bulb, increase of luminous efficiency through application of reflector globe through aluminum coating and development of 60[W] basking neodymium lamp through optimum insertion ratio of krypton gas and nitrogen gas. The results of this development shows that the life of the lamp was 7,200 hours, and the luminous flux was 620[1m]. This brings in superior color temperature and superior color rendering index, which allows us to use that lamp for agricultural or general purpose.

The prototype ASME III motor actuated Y-type globe valve has been tested to identify dynamic characteristics. The valve is Seismic Category I equipment and has the function to control water flow in the safety-related system. In this study, two different types of structural identification test i.e. swept sine and broadband random, have been performed at various levels of excitation to verify the effects of test method and excitation level on cross coupling effect as well as natural frequencies and damping values. It was found that swept sine test and broadband random test showed similar natural frequencies, and that the primary interaction was exhibited between horizontal and vertical axes.

본 과제는 지구본에 비행기를 융합한 놀이 및 학습 도구이다. 기존의 지구본은 낮은 연령대의 아이들에게 교육적 효과를 줄 수 있으며, 유아에게 호기심 유발이 적고 국한된 정보를 제공한다는 문제점을 가지고 있었다. 본 과제에서는 유아에게 더 많은 호기심 자극과 정보를 제공할 수 있게 상호작용적 기능이 내장된 스마트 지구본을 제안한다. 본 연구의 결과는 유아 및 아동들에게 교육적 효과를 줄 수 있고, 스마트폰 어플리케이션 연동으로 인한 간단한 거리뷰 및 지도를 나타냄으로써 다양한 목적을 가지고 활용할 수 있을 것으로 기대된다.

This paper presents the results of structural identification of a safety-related valve for nuclear power plant by impact hammer test as well as shaking table tests by using broadband random wave and sine sweep excitation. The test specimen is a Y-type motor operated globe valve. The test was performed as a "support test" to validate the analytically obtained modal parameters of the valve during its seismic qualification process by analytical method. From the study results it has been found that the shaking table test generally yields higher natural frequencies and lower damping values compared with those of impact hammer test. And it has been recognized that impact hammer test for modal identification of complex structures should be applied very carefully to get reasonable results.e results.

An eight-year-old Shih-Tzu dog was referred to Kyungpook National University Veterinary Medical Teaching Hospital because of severe glaucoma and exophthalmos. The symptoms included severe buphthalmos, conjunctival hyperemia, focal dried cornea and discomfort in the affected eye. Although enucleation was considered as a potential intervention measure in light of the severity of symptoms, it was possible to save the globe and relieve symptoms through evisceration, intraocular prosthesis implantation, and lateral canthoplasty. Our experience with this case suggests that symptomatic salvage therapy, rather than enucleation, is an appropriate approach for resolution of exopthalmos and other complications associated with glaucoma surgery.

A 15-year-old Schnauzer, showing right exophthalmos, was diagnosed as adenocarcinoma originated from the third eyelid gland. On computed tomography, a normal right third eyelid gland was not observed. Instead, a heterogeneous cystic mass invaded the retrobulbar space and displaced the eye globe dorsolaterally. In addition, lysis of the bony nasolacrimal duct was found, which was considered the tumor invasion. These findings indicated that third eyelid gland adenocarcinoma should be considered when a retrobulbar mass is found ventromedial to the globe without observation of the normal third eyelid and accompanies osteolysis of the bony nasolacrimal duct in dogs showing exophthalmos.
