The purpose of this study was to find out the most reasonable design in the superstructure of an underground parking lot which needs to be considered with the economic efficiency being influenced on the subdivision price, construction duration, workability and the maintenance of crack and leakage status of apartment house. In this research, we've evaluated the fitness for the superstructure of an underground parking lot by examination of construction constraint, which was based on the calculated data of structural design and quantity survey. The results of this study are summarized as follows. 1. The system of the absent structure of beam is proper structure for economic efficiency, construction duration and workability, but it is disadvantageous at the side of maintenance efficiency because of the many part of large slab. In the opposite direction, the establishing structure of beam has the advantages of structural stability except economic efficiency, construction duration and workability 2. It's required a proper selection for the views being contrary to each other which the owners considers good quality, on the other hand, the contractors consider construction duration and workability. 3. In making a selection for the superstructure of an underground parking lot, we have concluded that it is the most important to choose the proper structure for the demanded performance by contrasting with two system.

In this research, I finally came to a conclusion analyzing the connection among managing of each items in management expenses, the size of each complex and stories, and the term of using. (1) In the managing cost regarding to the management manner, although the managing cost of self-governing management is less imposed than the one of commission management, there is slight difference between those Costs. And it is more important to consider the effectiveness of management than to emphasize reduction of management cost. (2) The higher the stories, the higher the managing cost of elevator per the unit area. It Is caused by the fact that the father the distance of the elevator operating, the higher the electric charges. (3) The third of one of total management cost goes to pay the personnel expenses. So I found that the effective management of the expenses is available to reduce management cost. (4) The higher the stones, the lower the cost of personnel expenses including the cleaner cost. (5) The sum of costs assigned in repairment and management increases in proportion to the term of using. The costs assigned in special repairment and management are interacting to each other. (6) To reduce the management cost, we have to cut down the personnel in security guard that occupies one third of total management cost with application to the joint security system and operation of the self-governing guard. Through this process, it will be easy to accomplish the rationalization of contract with an outside order. Because the improvement of management service is not only the responsibility of owner but also the one of dwellers. And it Is imperative to realize the importance of cooperation and trust between the owner and dwellers. And the establishment of effective managing system which has convenience and rationality must be settled without delay.

Purpose: The present study was undertaken to determine the 24-hour pattern of intraocular pressure (IOP), and to reveal the effect of unilateral decentralization on circardian rhythm of IOP in eyes of rats. Methods: Nine male Sprague-Dawley rats were exposed to a 12-hour light/dark cycle for 3 weeks. 24-hours IOP pattern was measured at six time points (8, 12, 16, 20, 24, and 4 circardian time) by Tonopen XL tonometer in awake state. After unilateral sympathectomy (cervical ganglionectomy), IOP measurements were performed at the same time points on post-operation 1, 2, 3, and 4 weeks. Results: 24-hour IOP pattern of rats showed a rhythmic pattern that appeared to be sinusoidal with 12-hour light/dark cycle. IOPs were low during the light phase and high during dark phase. After unilateral sympathectomy, the circardian rhythm of IOP was maintained in control eyes. But in sympathecotmized eyes, the circardian thythm of IOP was loss. Conclusions: These results show that sympathetic nervous systems contribute to the circardian rhythm of IOP in rats. J Korean Ophthalmol Soc 2008;49(11):1839-1844

Purpose: The result of embolization via an external superior ophthalmic vein approach of carotid cavernous sinus fistula was first described around 1970s. We report a case of coil embolization of carotid cavernous sinus fistula using a superior ophthalmic vein approach. Methods: A 70-year-old female had a 3-month history of headache, periocular pain, and diplopia. Diagnostic orbital contrast-enhanced CT, brain MRI and contrast-angiography and cerebral angiography revealed a carotid cavernous sinus fistula. Fistula occlusion via transfemoral endovascular embolization failed, so we then tried coil embolization using an external superior ophthalmic vein approach of carotid cavernous sinus fistula. Results: The coil embolization via an external superior ophthalmic vein approach was difficult because of venous tortuosity and poor exposure of part of orbital roof area. But, X-ray-guided direct puncture of the superior ophthalmic vein was successful. We thus had good results with coil embolization of carotid cavernous fistula. Conclusions: The coil embolization via superior ophthalmic vein approach is an effective and challengeable treatment when surgical cauterization or conventional endovascular embolization fails. We suggest that there is need to training ophthalmologists to be experienced in external orbital surgery.

As the area where stone is used in buildings increases, the amount of stone processing increases, and the amount of dust generated in the processing process is increasing, but interest in this is insignificant. In addition, as a result of investigating the dust generated in the dry process, the proportion of SiO2 is about 70%, so there is a concern about the risk of pneumoconiosis caused by breathing. Therefore, it is judged that it is urgent to collect it at the source to prevent damage to workers and environmental pollution.

Even though the Al. form system, which was developed to replace the Euro-form, has been used as the slab lower formwork for almost all concrete structures based on the light weight and high conversion rate, the low-noise Drop method has been developed and used in order to overcome the limitations of the Al. Form system such as noise pollution and safety accidents caused by free fall during the demolding. However, as the low-noise drop method is still insufficient, Safety Full Drop Al. Form method is expected to be in the spotlight in the construction market based on its excellent advantages compared to the developed methods. In addition, we plan to conduct research to further contribute to securing the quality of the overall structure through continuous improvement and supplementation by introducing an automation system to the very construction method.

Accordingly, we made slow cooling ground granulated slag powder of which fineness is 7,000, 10,000, 20,000㎠/g by using<br/> grinder and examined properties of concrete using that in this study. We carried out slump test, air contents test and<br/> compressive strength test to examine properties of concrete according to fineness of slow cooling ground granulated<br/> blast-furnace slag, substitute ratio, additive quantity and additive way of calcium hydroxide. The results are as follows<br/> (1) Slump and air contents of concrete using slow cooling ground granulated blast-furnace slag varied with fineness and<br/> substitute ratio of it but were similar to plain concrete.<br/> (2) Compressive strength increased according to rising of fineness of slow cooling ground granulated blast-furnace slag and<br/> declined with rising of substitute ratio of it. We judged that fineness of slow cooling ground granulated blast-furnace slag has<br/> to be more than 20,000㎠/g to use it as concrete admixture through comparing compressive strength of plain concrete with it of<br/> all water curing.<br/> (3) Compressive strength of concrete of slow cooling blast-furnace slag ground granulated was improved according to adding<br/> accelerator. In case of way adding powder at 4%, 6% and diluting with water at 6%, 8% was excellent.
