The purpose of this study is to investigate the actual conditions of current shroud. People began preparing their shroud after their 60th birthday anniversary. To keep the prepared shroud unharmed mothballs leaf tobacco and kungkungi were placed inside. The size was larger than everyday clothes. The size of the men's shroud was 390 Ch'ok and that of the women's shroud was 330 Ch'ok in formal funeral ceremonies. But size would be determined by the person's standard of living or economic situation. According to the proposed size of shroud illustrated in table 10 and the size was 5 to 30cm larger than every-day clothes. The shape of the shroud was various that Ryomp'o represented by the cross and so on.

Flow velocity changes in the shroud system for tidal current power generation due to experimental flow velocities and blade geometry changes were analyzed by hydraulic experiment and numerical simulation. Through the hydraulic experiment, flow velocities at inlet of shroud system and RPM according to blade geometry were measured, and numerical simulation was used to analyze flow velocity changes in shroud. When the experimental flow velocity was increased by about 28% and the shape of the airfoil was applied, the measured flow velocity at the shroud inlet tended to increase by up to about 56%. On the other hand, when airfoil-shaped blades were installed, the flow velocity at the inlet tended to increase by up to 14% compared to conventional blades, and RPM was also the highest at the same conditions. The hydraulic experiment and numerical simulation results showed an error of about 13%, and the trends of the flow velocity changes in each result are similar. Numerical simulation of the flow velocity changes in the shroud showed that the flow velocity tended to increase 1.7 times at the front of the blade compared to the inlet. The results of the flow velocity change analysis in the shroud system obtained from this study will provide the basic data necessary for the development of efficient shroud system for tidal current power generation.

This study researches the current status of shrouds and analyzes the current status of the Hanji shrouds and sets its goal on suggesting the direction for a futuristic shroud design, suitable for the changing funeral culture. For this, the characteristics of traditional shrouds were studied, standard shrouds' and Hanji shrouds' current statuses were researched and analyzed to suggest the development diretion for design of Hanji shrouds. The results of the research showed that the Hanji shrouds are superior in cremation and burial, and the design expressions were more effective. Also the previously established shrouds were shown to have an increase in value through use of different materials, changing designs through various patterns, or through the added symbolic value. Thus the direction of shroud development designs based on the advantages of Hanji have been drawn out to as follows: First, traditional shrouds used the ceremonial dresses, such as official uniforms or wedding dresses, from the Tang dynasty which made it multicolored. Afterwards colors were limited with the use of hemp clothes shrouds but with the appearance of Hanji shrouds, the possibility for mulitcolors and patterns became larger. Second, Hanji is superior in its expression of colors and patterns, making designs with symbolic sides such as religion possible, to meet the demands of the customers. Third, Hanji shrouds are more environmentaly friendly than the standard shrouds in cremation and burial, and it presents a much better image of shrouds for the future society. Such development of Hanji shrouds design developments satisfies the distinct and gentrified demands of the customers and it looks to be able to suggest an opportunity for environmentaly friendly actions while preparing itself for the chaning market demands and values.

Numerical analyses through Computational Fluid Dynamics have been performed to investigate the seawater flow field characteristics for various shrouds used in horizontal axis tidal current turbine systems. Seawater flow characteristics are largely influenced under constant tidal current velocity by the shroud geometry and there is considerable difference in fluid velocity distributions around the shrouds. Especially the location and magnitude of maximum seawater flow velocity directly affect turbine performance for power generation. For the cylinder-diffuser type shroud system whose cylinder and diffuser parts have the same length accelerated flow region is formed in the overall cylinder part while maximum velocity in the nozzle-diffuser type whose nozzle and diffuser parts have the same length with symmetry, locally appears near the minimum sectional area. In case of cylinder-diffuser type shroud fluid velocity increases rather high compared with current velocity. And fluid velocity at the centerline gradually increases from the entrance, and then decreases rapidly after reaching a peak close to the middle of the cylinder part unlike the nozzle-diffuser while there is not much variation near the rear of the shroud. These results of the seawater flow characteristics with various shroud geometries can be applied to optimal design for the development of efficient tidal current power generation systems.

Current tanks have been developed to increase mobility and firepower, and its maximum range and destructive power are improved. This great change causes remained vibration of a gun barrel after firing. For this reason, people are trying to control vibration of gun barrel effectively. This thesis presents a modeling method and analysis results for gun barrel by using a thermal shroud as an absorber mass. DTS(Dynamically Tuned Shroud) is a vibration damping system using a thermal shroud as an added mass for decreasing remained vibration. The model has an advantage that the gun barrel's vibration can be decreased by dissipating a kinetic energy of thermal shroud without install an additional dynamic absorber to tip of the gun barrel. For analyzing the damping performance of the DTS, We derived an equation of motion of the barrel after setting a mathematical modeling, and found out the frequency analysis and tendency according to stiffness ratio between barrel and shroud.

A shroud is clothes for giving a dead person a bath and being finely dressed:though our routine clothes have been western, putting on a shroud has been kept comparatively well as a tradition of a conventional ceremony garments. This study is about the current using of dressing a shroud, and for presenting foundations of a way about dressing a shroud in order to make the most of this by everyone, therefore this research will be worthwhile to preserve the traditional custom of giving a dead person a bath and being finely dressed. 1. We must confirm the death of a person before we do Su-Si for controlling rightly a corse. Su-Si is ways of changing a clean clothes after bathing the dead person, tieing up hands, feet and ankles with a string, filling up a mouth, a nose and ears with a wad of cotton, laying down the dead person with his head toward east, and setting up a screen after covering the dead person with a bed sheet. 2. Here are processes of putting on a shroud. After the day of death, first of all, you must untie the string to control rightly a corpse, take off the clothes, and give a dead man a bath. You trim the dead person's fingernails and toenails, put them in O-nang, then put his hands and feet in five pouches, finally put feet in korean socks and wrap with Ak-su. You put a underwear in a overwear in order to put on the clothes easily, and then put on an upper garments after putting on trousers. And put on Sb-sin After you wash the dead person's face and his hair, you put gems and raw rice in his mouth, wrap head with cotton fabrics, and put hairs into five pouches, then put on a headgear which is filled with five pouches. 3. You tie up with hem cloth the dead person dressed a shroud after wrapping with Dae-ryum-km and So-ryumkm. 4. After you encoffin the dead person, you weave coffin strings with cotton fabrics in order to lift up the coffin easily, and lay down a red fabrics having white letters about the dead person's name or social position onto the coffin, then cover the coffin with a coffin cover : finally you leave the coffin at the former place and set up screen.

In this paper, a successful result of modification of an axial flow fan and a shroud for noise reduction of a window type air conditioner is presented especially in order to verify the importance of blade shape improvement and the searching for the optimal shape of shrouds. Effective ways to work out the result as mentioned above are to make the tip of the blade varied in thickness and to have special shapes. From the viewpoint of the shape in a shroud, several cases were examined and the particular value of a design parameter of the shroud was acquired to get the best noise reduction of an air conditioner. Through the application of the methods, the air conditioner became less noisy by 4.5 dB(A) in terms of air-borne noise produced only by the axial flow fan and consumed less energy by 20.9% compared to the current one.
