  • This study was conducted to present the fundamental data on physicochemical properties and sensory evaluation of salad dressing by chicken foot gelatin. Preliminary experiments were performed for conforming the concentration of gelatin powder to make the gelatin solution. Gelatin solution of 2% including agar of 0.5% was fixed for using the followed experiments. Sensory evalution was conducted to compare the organoleptic acceptance of dressing manufactured with the difference of the concentration of additives, seasoning soybean sauce, mayonnaise, and sesame powder. Gelatin-dressing prepared with seasoning soybean sauce of 10% appeared the most acceptance. In mustard mayonnaise dressing made with gelatin solution, 10% of mayonnaise added was good in low concentration. Sesame dressing prepared with gelatin solution by adding sesame powder of 30 g was excellent. Shear stresses to shear rates of dressing were tested at 45$^{\circ}C$. Viscosity of soybean sauce dressing decreased following to increase of the content. However, mustard mayonnaise and sesame dressing appeared the opposite results. Viscosities of the dressings statistically increased by the increase of the concentration of the addition of gelatin powder. The decrease of turbidity was observed in mayonnaise dressing and in sesame dressing. Color difference values of all dressings did not appear any differences. At sensory test to the dressings prepared with gelatin solution of the different concentration of 1, 2 and 4 % of gelatin powder, dressings with 2%(4 g) of gelatin appeared the highest score in overall acceptance in all samples. In this study conducted to efficiently use a waste product of chicken house, chicken foot, the use of the chicken foot is expected as a new raw material for producing collagen and gelatin, protein source widely increasing in the field of food and bioindustries.

  • This morphological study was carried out to investigate the healing effect of open and occlusive dressing on rabbit skin wounds. The male white rabbits were given incision wound measuring 1.0cm in length and excision wound measuring $1.0{\times}0.2cm$ respectively on backs. Five rabbits among their received sterilization with beta dine twice a day and kept wound open. Another group of rabbits received sterilization and occlusive dressing with application of 1% sulfadiazine ointment and covering of gauze. The rabbits were observed at 5, 10, and 15 days after dressing with light microscope. The results were as follows. Both incision and excision wounds received open and occlusive dressing respectively revealed formation of scab and regeneration of epidermal epithelial cells at wound margin. The superficial dermis showed infiltration of neutrophils, monocytes, and lymphocytes, fibroblastic proliferation, and edema. On 10 days after opera and occlusive dressing the scab had disappeared and regeneration of epidermal epithelium was completed. The capillaries and inflammatory cells were decreased in number. However, edema and fibroblastic proliferation were more pronounced. On 15 days after opera and occlusive dressing, there were keratinization of regenerated epidermal epithelium, loss of inflammatory infiltration, edema, and capillary proliferation, and increase of fibroblastic proliferation and collagen fibers. The amounts of scars were less in incision wound than of excision one. There were no differences in healing processes between both dressing methods. According to the above results, it was conceived that sterilization of wound is more important in wound healing than dressing method in trivial wounds.

  • With a purpose of finding out the effects of magnesium and boron enriched organic-compound fertilizer application on qualities of grasses on the hilly pasture, a field experiment was arranged with five different treatments as a randomized block design and lasted from September, 1984 to the end of growing season in 1986. The results obtained are summarized as follows: 1. Mean chemical components except NFE of grasses at the plots with organic-compound fertilizer application were appeared to contain slightly high comparing to single dressing. 2. Production of DCP with organic-compound fertilizer (1,170.2 kg/ha) was significanty increased by 20% comparing to single dressing (975.7 kg/ha) in the conventional fertilization level (p<0.05), but it was not significantly different between them in the low dressing level. 3. Production of energies (TDN, StE and NEL) with organic-compound fertilizer of low and conventional dressing level were appeared to increase by 10 and 13 to 15% than those of single dressing of the same levels, respectively. But it was not significant difference. 4. Like single dressing nutrient productions with organic-compound fertilizer were appeared significantly high due to increasing of dressing gradually (P<0.05-0.01) 5. Mineral contents of P and Mg at the plots with organic-compound fertilizer were a little higher, on the other hand, K, C/P and K/Ca + Mg equivalent ratio were slightly lower than those of single dressing, but the content of Ca tended to similar between them.

  • Effects of nitrogen top-dressing method on quality of barley were evaluted over amount of 2 and 4 kg per 10a on volcanic ash soil in Japan under regrowth stage, productive tiller stage and heading stage. 55% milling time was longer by the amount of top- dressing, but that was not influenced by the times of top-dressing. And glassiness, whiteness, hardness and 8 minute- millng rate were not influenced by times and amounts of top-dressing. Crude protein rate of grain was increased by amount of nitrogen top-dressing, but that did not correlated with time of nitrogen top-dressing. Crude protein rate of grain was positively correlated with 55% milling time. But that did not correlated with whiteness of 8 minute-milled grain. 8 minute-milling rate was negatively correlated with whiteness of 8 minute-milled grain. There was no visible difference of protein matrix with scanning electron microscope in different nitrogen levels.

  • The effect of vinegar concentration (+30%, 0% and -30%) on the emulsion stability of mayonnaise dressing was studied by the measurement of theological test and sensory evaluation. The emulsion stability of mayonnaise dressing increased with increase in vinegar concentration. The results of steady shear theological test indicated that C sample of the highest vinegar concentration (+30%) exhibited higher emulsion stability than other samples. The dynamic shear datas were similar to steady shear theological data. The mayonnaise dressing samples showed time dependence, which was quantitatively described by the Weltman model. Parameters A and B indicated that the structure of C sample exhibited more stable than that of A (-30%) and B (0%) samples. The amount of oil separation was less than that of A and B samples. The results of sensory evaluation were similar to those of theological and emulsion tests.

  • In-process Electrolytic Dressing is a lapping method using electrolysis. This technology provides dressing to CIB-Diamond Lapping wheels during the lapping process for continuous protrude abrasive from super-abrasive wheels. so loading and glazing are disappeared apparently. Ultra-precision lapping of the machinable commies will be studied in the viewpoint of In-process Electrolytic Dressing. For ultra-precision lapping, need to develop an ultra-precision lapping system suitable metal bonded diamond wheel, and appropriate condition of u10a-precision lapping machining.

  • The establishment of a practical ultra-precision grinding technique using Diamond and CBN wheels is one of the major key technolo-gies to improve production techniques for machine-to-difficult materials without finishing process such as lapping and polishing. But the special efficient dressing technique for ultra-fine grit type grinding wheels to stabilize the grinding ability was not developed. Recently electrolytic in-process dressing technique is proposed to ultra-fine grit type metal bonded diamond wheels to protrude abra-sives continuously from the tool surface. This technology can be widely used to surface grinding and cylindrical grinding but cannot be used efficiently to internal grinding because of the electrode attachment trouble. This paper describes the effect of interval type electrolytic dressing as proposed newly to cast iron bonded diamond wheel for efficient internal grinding with mirror type high quality ground surface.
