The unsaturated polyester(UP) and epoxy resin have a superior material properties and a chemical resistance using sewerage pipes rehabilitation. However, UP and epoxy have not a low temperatures harding, the requirement $8{\sim}11$ hours long times harding and heating system used by reinforcement liner. This study is to evaluate the effects of low temperature harding properties methyl methacrylate(MMA) monomer using expanded polystyrene(EPS) and UP in addition of initiator and promoters. From the test result, viscosity tends to increase with increasing EPS and UP contents. However, harding time change of the MMA resins which it follows in addition of the initiator and promoter.

Cupid's bow, upper lip, columella, and ala of nose are esthetically important, in which their symmetrical plasties determine success or failure of the surgery in cleft lip and palate patients. Z-palsty and its modifications are simple and effective. The double Z-plasty is economical in surgical time and esthetics in reconstructing the cupid's bow compared with other methods. We report a 29-year-old male patient who represented reversed cupid's bow and whistle deformity after the primary repair of the cleft lip. He was corrected the cupid's bow using a double Z-plasty. The reversed cupid's bow was corrected to a normal shape and the whistle deformity disappeared. The tightness of the upper lip was relieved after the operation. The double Z-plasty was esthetically successful because the procedure was limited in the vermilion and did not produce a new scar on the skin. Furthermore, the lip tubercle became protuberant. The cupid's bow was symmetrically smoothly curved at 4 years after the operation. These results indicate that the double Z-plasty is simple, less traumatic to the surrounding tissues, and suitable for the correction of whistle deformity.

Surgical extrusion, immediate extrusion following tooth luxation, is a method to preserve one's natural tooth and achieve esthetic restoration without additional periodontal surgery when subgingival dental caries or crown fracture occurs. A 16-year-old male was referred to the clinic from the department of operative dentistry for the esthetic restoration of maxillary left lateral incisor. Due to the crown to root fracture, the tooth was endodontically treated with a buccal crown length of 4 mm. When the palatal flap was elevated, the mesiopalatal cervical fracture area was situated 3-4 mm subgingivally. Crown lengthening was achieved through surgical extrusion. After 3 months of clinical observation and provisional restoration, the maxillary left central incisor was restored with all ceramic crown and obtained a satisfactory clinical result.

This experiment was conducted to find out the effect of day length on the production of high quality plug seedlings in onion (Allium cepa L.). Two cultivars, ‘Changnyongdaego’ and‘Wolryun’, were grown to seedlings in 200-cell plug trays under 11.5, 12.5, 13.5 hours and natural day length. These seedlings were transplanted to the pot (16 cm In diameter) and grown under 16 hours day length. Number of leaves and neck diameter showed better growth in the longer than shorter day length treatments, but plant height old sheath length were retarded in the longer day length treatments. Growth such as no. of leaves, neck diameter, plant height and sheath length increased with the passage of day, but plant height and neck diameter decreased by treatment over 20 days with 13.5 hours day length. Bulbing and bulb size of onion after transplanting were enhanced in the seedlings cultured under longer day lengths. From the above results, treatment of long day length during seedling culture in plug tray can control the overgrowth and produce high quality plug seedlings.

The effects of adding fish surimi to Gouda cheeses on quality characteristics during ripening were investigated. Cheese samples were prepared with 1.0% fish surimi, changes in chemical composition, lactic acid bacterial population, pH, non casein nitrogen, non protein nitrogen, water-soluble nitrogen, were monitored every 3 weeks during ripening. The electrophoresis patterns of cheese protein and the consumer's sensory evaluation test of Gouda cheese added with fish surimi also were analyzed. Slightly higher amounts of moisture, crude ash, crude protein, and crude fat were observed in the cheese supplemented with the fish surimi compared to the control cheese. The results suggested that the Gouda cheese prepared with fish surimi did not affect appearances or consumer's sensory characteristics of the cheeses.

To confirm the effect of electroacupuncture on the regeneration of injured peripheral nerve, the change of evoked potential in the sciatic nerve, the change of enzyme activity in the spinal cord, and morphological change of injured sciatic nerve were examined comparatively in acupuncture group (AG) and control group (CG) after sciatic nerve of guinea pig was injured by purpose. The value of evoked potential after injury of the sciatic nerve was increased in both AG and CG, but the increase rate of that was higher in AG than CG. Acid phosphatase activity of the spinal cord was increased in 1CG and 2AG, but shown are tendency to return to the normal state as time went by. Ultrastructural recovering rate of the injured sciatic nerve was higher in AG than CG. Also, there was developed only adipose tissue in sciatic nerve of AG. As mentioned above, the effect of electroacupuncture on the regeneration of injured peripheral nerve was confirmed experimentally by change of evoked potential, acid phosphatase and ultrastructure. Especially, the effect of electroacupuncture was appeared clearly in an early stage than other treatment stages.

The effects of adding fish surimi to Appenzeller cheese on quality characteristics during ripening were investigated. Cheese samples were prepared with 1.0% surimi. Changes in chemical composition, lactic acid bacterial population, pH, non-casein nitrogen, non-protein nitrogen, water-soluble nitrogen, a consumer sensory evaluation test, chromaticity, texture, and proteolysis were monitored during ripening. The electrophoretic patterns of cheese proteins and the functional components originating from the surimi were investigated. Adding surimi did not affect the appearance or consumer sensory characteristics of the cheeses. Significantly higher amounts of crude fat and moisture were observed in the cheese supplemented with surimi than in cheese without added surimi.

This study explored the essential meanings of experiences that married immigrant women living in rural communities have in their community participation process and analyzed the situations and types of their community participation in order to support immigration women's community participation and develop strategies for social welfare by type of community participation. For these purpose, we analyzed story outlines, meanings, types and situations of community participation among married immigrant women who had been over 5 years since their immigration. According to the results of this study, the meaning of married immigrant women's community participation was "Recognize myself as the pioneer of my life and participate in social activities continuously." In the results of analyzing the types of participation, the subjects were classified into 'self directed growth type,' 'self content type,' and 'social support expectation type.' The results of this study are expected to be helpful to understand the life of married immigrant women in rural areas not as 'individuals' otherized in a foreign country but as 'participants' of community that are encountered naturally in daily life, and to develop community level services suitable for such women.

Recently, due to the deterioration and various natural disasters caused by the passage of concrete pole for 20~30 years or more, damage and destruction of the poles have increased the demand for maintenance. In this paper, 10 flexural strength test specimens were fabricated by using crack self - healing concrete of Fly ash, GGBS, CA, etc. The compressive strength of the concrete with slag was found to be excellent, but the concrete with fly ash was slightly below the reference strength. In addition, the crack loadings of the specimens satisfied the criteria of KS F 4304. In the case of the load-deflection and strain relations, the behavior of the fly ash specimens was similar, but in the specimens containing the blast furnace slag, The results showed that a large amount of strain occurred.
