Many poeple has been engaged in industry is aware of the dangers from exposure to high intensity nose levels. The exposure to high intensity noise is encountered in a large number of situations. Laws governing the safety and health of employed people being to create a suitable working environment and eliminate unsafety practices and processes. Work areas should be designed and laid out so that they are satisfactory both from the environmental and safety points of view. In this connection safety also implies that noise is kept at a level which is not likety to cause hearing damage. This study was performed to measure the noise of press and assembly process in an automobile factory. and suggested the method of noise control. Consequently the effect ways of reducing level in working environment are as follows; 1. Changes to machines which would reduce noise generation. 2. Alteration of equipment to avoid impact in machinery and handing materials. 3. Enclosure of noisy machines or machine parts. 4. Mounting of attenuators on gas and air outlets as well as ventilation ducts. 5. Erection of sound absorbing screens. linings. and baffles in work areas. 6. The personal ear protectors can be chosen to protect the workers.

The application of three-dimensional (3-D) CAD has been popularized for design and production and digital manufacturing has been spreading in many industrial fields. By simulation of the production process using 3-D digital models, which are the core of CIM (Computer Integrated Manufacturing) system, the efficiency and safety of production are improved at each stage of work, and optimization of manufacturing can be achieved. This paper firstly describes the concept of "simulation based production" in shipbuilding and also digital manufacturing; the 3-D CAD system is indispensable for effective simulation because ship structure is three dimensionally complex. By simulation, "computer optimized manufacturing" can be possible. The most effective fields of simulation in shipbuilding are in jobs where many parties have to cooperate, while existing two-dimensional drawings are hardly observed the whole structures due to interference between structures or equipment of complex shape. In this paper some examples of the successful application in IHIMU (IHI Marine United Inc.) are shown: assembly of a pipe unit, erection of a complex hull block, carriage of equipment, installation of a propeller, and access in an engine room.

After Japanese Invasion of Korea in 1592 was over and the situation was coped with, Chang-Kyoung Palace and Chang-Duk Palace were rebult, and In-Kyung Palace and Kyung-Duk Palace were built during the reign of Kwang Hae Kun. Many utilitarians were engaged with the construction as a manager, and they devoted themselves to improve technology. As a result, craftsmen were treated so valuable, compared to the past, that they were consulted about the technical problems under construction, the process of making an estimate, and the management of construction materials. Moreover, famous craftsmen obtained the government service. And there were various attempts on organizing and compensating workmen in order to manage them efficiently. In addition, the know-how of manufacturing a blue tile, which had been failed to succeed due to the war, was revived, and manufacturing a yellow tile, which had not been used, was studied by utilitarians. Finally, There were many kind of technical attempts and development under the construction of palaces, which gave utilitarians a chance to express their ideas, expected practical science, and assembled craftsmen who had scattered due to the war, during the reign of Kwang Hae Kun

One of the most important things for quality to meet ship-production schedule is an accuracy control. A ship is assembled by welding through whole production process, so it is important that loss by correction will not happen as much as possible by using some engineering skills like reverse design, reverse setting and margin for thermal shrinkage. These efforts are a quite effective in fabrication stages, but not in erection stages. If a ship block which consists of common steel is exposed to directional solar radiation, its dimensional accuracy will change high as time by its thermal expansion coefficient. Therefore, the measuring work would be often done at dawn or evening even with having a very accurate device. In this study, an FE analysis method is developed to solve this problem. It can change measured data affected by solar thermal distortion to ones not, even though ship-block is measured at an arbitrary time. It will use the time when measuring, the direction of block and the weather record by satellites. It is confirmed by a comparison between measured data of a ship-block and the result by suggested analysis method. Furthermore, a pre-processing system is also developed for fast application of the suggested analysis method.

This paper introduces a new composite joint, which is the composite CFST beam- concrete column joint, and it is more convenient for transportation and erection than conventionally welded joints. The main components of this joint include steel H-beams welded with CFST beams, reinforced concrete columns, and reinforced concrete slabs. The steel H-beams and CFST beams are connected with a concrete slab using shear connectors to ensure composite action between them. An experimental investigation was conducted to evaluate the proposed composite joint performance. A three-dimensional (3D) finite element (FE) model was developed and analyzed for this joint using the ABAQUS/explicit. The FE model accuracy was validated by comparing its results with the relevant test results. Additionally, the parameters that consisted of the steel box beam thickness, concrete compressive strength, steel yield strength, and reinforcement ratio in the concrete slab were considered to investigate their influence on the proposed joint performance.

Impotence is defined as a consistent inability to achieve or maintain penile erection that is adequate for completion of sexual intercourse. In oriental midicine, the chief cause of impotence is the decline of the fire from the gate of life, and in western medicine that is psycogenic and organic. Because of the increase aging people and psycologic stress that modern people get, impotence became common. This bibliographic study on impotence in the oriental and western medicine books has come to the following conclusions. 1. The main cause of impotence in the oriental medicine is the decline of the fire from the gate of life(命門火衰), followed by the deficiency of both heart and spleen(心脾兩虛), the depression of Liver energy(肝氣鬱結), and attack of blended wetness and heat to the lower wanner(濕熱下注). 2. The theraphics of impotence in oriental medicine are warming and strenghthening Kidney. softness of Liver energy, tonifying the Kidney to relieve mental strain, clear away the wetness-heat, and infairment of Heart and Spleen. 3. The prescriptions of impotence are Yugyeyum, Gyibitang, Soyosan, Sunjitang, and Yongdamsagantang. 4. In the western medicine, psycotherapy, medical therapy and surgical therapy are the major way to treat impotence.

Erectile dysfunction is defined as the inability to attain and maintain penile rigidity sufficient to allow sexual intercourse. Although erectile dysfunction is usually considered a benign disorder, it has a dramatic impact on quality of life of the patients as well as their sexual partners. And it is common in men between the age of 40 and 70 years, and its incidence increases with age. The prevalence is reported to occupy 10% at the age of 40 years, 20% in 50s, 30% in 60s and 50% at the age of 70 years, and is more prevalent as stress in modern life and interest onsexual behavior increase. This article has aims to investigate and summarize the current trend of treatment for erectiledysfunction so as to suggest the effective and available way to treat the disease. In oriental medicine, erectile dysfunction has been treated with herb medicine and acupuncture with good results. Some of herb drugs have the substances which induce penile erection. So it should be investigated on the neurotransmitter or endothelial mediator which can be included in herb drugs. The acupuncture therapy stimulates the erectile nerves and is reported to be effective for erectile dysfunction. And suppository, locus injection therapy and topical agent are found to be effective as well as stellate ganglion block and biofeedback treatment. So the study on the approach and application of these treatments on erectile dysfunction would be necessary.

The medial sural artery perforator (MSAP) flap is a versatile fasciocutaneous flap that has been used successfully in the reconstruction of defects across the body. In specific cases, it may prove superior to more commonly used options (e.g., anterolateral thigh flap and radial forearm free flap). Historically, a disadvantage of the MSAP flap is the relatively small surface area it provides for reconstruction. We recently encountered a patient with extensive pelvic injuries from prior trauma resulting in significant scarring and contracture of the groin, tethering of the penis, and loss of the scrotum and one testicle. The patient was unable to achieve erection from tethering and his remaining testicle had been buried in the thigh. In considering the reconstructive options, he was not a suitable candidate for a thigh-based or forearm-based flap. An extended MSAP flap measuring 25 cm×10 cm was used for resurfacing of the groin and pelvis as well as for the formation of a neoscrotum. This report is the first to document an MSAP flap utilized for simultaneous groin resurfacing and scrotoplasty. Additionally, the dimensions of this flap make it the largest recorded MSAP flap to date.

Purpose: Urethral reconstruction following failed hypospadias repair is difficult because of a severe shortage of the skin on ventral surface of the penis. We experienced a successful reconstruction of a failed hypospadias repair using the radial forearm free flap. So we present our case. Methods: A 16 - year - old boy had a proximal shaft hypospadias and had been taken a transverse preputial island flap but it completely broke down. There was no spare skin on the shaft of the penis. So we reconstructed a neo - urethra and the ventral skin of the penis with the radial forearm free flap. Results: Postoperatively he made relatively good process. The urethral catheter was maintained for 10 days and self - voiding was started. The suprapubic catheter was removed at the postoperative 30th day after control of cystitis. The postoperative appearance of the penis is acceptable and a straight erection is achieved. Conclusion: In the scarred penis with hypospadias, the radial forearm free flap transfer is a reliable reconstructive method for the neo - urethra and the ventral skin of the penis.
