The purpose of this study was to investigate the characteristics of traditional blue color between Korean and Japanese traditional costumes. Korea and Japan as the neighboring country of geographically and historically, but showed obvious difference in traditional color. In this study we investigated the blue color characteristics that appear on Korean and Japanese traditional costumes. We researched the characteristics of blue color on color names and color tones through the old Korean and Japanese literatures, costume remains and restoration dyeing fabrics. This study researched the Chosun Period in Korea and Edo Period in Japan. The results of this study Were as following; Many differentiation colors appeared in Chosun and Edo period than former ages. These differentiation colors were made giving differences gradually in basic color, hue, value and chroma. The blue color names appeared 40 names in Chosun Period and 57 names in Edo Period. In these blue color names of Chosun and Edo Period, the common color name was not more 'indigo'. The most highly appearanced blue color hues of costume remains in Chosun and restoration dyeing fabrics in Edo Period were blue and purplish blue. The most highly appearanced blue color tones were dull and moderate. By result of preceding descriptions, the characteristics of national color were not come from difference of dye and dyeing method, could know that come from difference of society and cultural environment.

An objective of investigation survey was made to personnel were comparative an educated level significantly higher such as college graduated 48.8％ this rate of value has most higher, High school graduated ; 30.1％ and middle School gratuated were 11.7％. In addition the native comes from large city, Farming and fishing villages an rural area rate were shown as 29.6％, 28.4% and 19.9% each other. There by classification of occupational job was shown by students has 27.4％ are most higher significantly, also there sales and service field job appearanced 15.1％ and expert technical job is 9.0% Although nonreligion person rate were 37.3%, buddist, Christianity, Roman Catholicism all them each other shown 33.6％, 16.7％ and 12.4%. An evaluation in economic situation value rate was appearanced by middle class level 61.7％ and higher and low level are 14.4％ and 23.9% with each other and married were 59.2％. 3. The people resident in cities area has pratice of health development by exercise person were 43.5% and value of rate for male has exercise practice is 52.5％, was significantly higher than female has by age group 10 years old and age group 50 years old is 52.6％ and 47.3％ was comparative higher rate also age group 30 is 35.1％ of low factor was indicated. Although evaluated an economic situation rate was higher level get more taken the practice of health develop exercise(higher level 60.0％ and low level is 32.9％). Although by higher level of educated were more taken pratice of their proper physical exercise(college graduated rate ; 52.2％ of most higher and high school graduted ; 39.7％ and then middle school graduated is 19.1％) unmarried taken exercise rate ; 48.4％ is significantly higher than married person rate ; 40.8％. Although objective of native area of exercise rate of Urban area cities ; 52.5％ are significantly higher farming and fishing native person rate ; 40.4％ shown is most low.

This thesis describes the effect of heat treatment on the magnetic properties of Co-bsaed Amorphous. A sample was chosen as basic composition with Co$\_$82//Si$\_$2//B$\_$16/ of zero magnetostriction. It was made by single roll method with quartz orifice 0.5[mmø], Ar gas pressure 0.6 [kg/cm$^2$] and roll speed 28 (m/sec) and atmosphere is ,Ar gas. We obtained the sample of width 2.4(mm), thickness 45[$\mu\textrm{m}$]. Made sample annealed for the improvement of magnetic propertics at at annealing temperature 325,350,375 and 400$^{\circ}C$ and annealing time 15, 30, 45, 60 and 120min respectiveily. Amorphous ribbon of co-based showed high permeab- ility ${\mu}$=8000∼14000, and became improvement of magnetic properties according to anneal ins temperature and time. Especially. Amorphous sample at 325$^{\circ}C$ ,45min appearanced high permeability ${\mu}$=13, 589 at frequency f= 100Hz. and loss factor was reduced at low frequency with rising anneal ins ti me and temperature more annealed sample than basic sample.

This study was conducted to comprehend the spatial distribution characteristics, habitats and appearances of Hydropotes inermis by using the biotope mapping in Daebudo Island, Ansan-si. The result is base data to understand status and manage potential inhabitation of Hydropotes inermis in Daebudo Island through the Maximum Entropy model. The study used 105 traces from the primary investigation and 452 traces in the secondary investigation. The biotope types were distinquished Hydropotes inermis habitats largest from the order of natural forest (15.1%), natural coast (13.7%), marshy cultivated land (12.6%), and dry cultivated land (11.7%), and from the inhabitation trace results. Hydropotes inermis appearanced biotope types were the greatest in the order of cultivated land (49.73%) > forest (18.85%) > coast (7.00%) > grassland (6.28%). Since forests in Daebudo Island have low slope and altitude, it was concluded that Hydropotes inermis would live in most of the forests. A high number of Hydropotes inermis was found to appear in areas where the grassland is formed including cultivated lands (include unused paddies and fields) and marshy grasslands, which would result in direct damage of crops. According to the Maxent modeling analysis that used location information of Hydropotes inermis, the AUC value was 0.635 based on the ROC curve. In Daebudo Island, areas with over 0.635 potential inhabitation value are distributed all over the place, and it was concluded that each population would have a different scope of influence and home range. Hydropotes inermis living in Daebudo Island have high habitat suitability mainly around the cultivated lands near the roads, but due to the bare lands and roads, it is expected that their habitats would be fragmented and damaged, which would have a direct and indirect effect in maintaining the Hydropotes inermis population. Also, considering habitat disturbance, diverse methods for reducing damage including capturing some individuals within the limit that does not disperse Hydropotes inermis population in Daebudo Island must be carried out.

The purpose of this study was to observe the effect on teeth and tibia bone histopathologically in rats by the richitogenic diet. For this purpose, 48 sprague-dewley rats, weighing 80g or more, divided into 6 groups, and sacrificed on the 1st, 2nd, 3rd, 4th, 5th, 6th weeks after experiments respectively. The tissues contain tooth, and tibial bone were fixed in 10% normal formalin solution, decalcified in Plank-Rychlo solution, embedded in paraffin, sectioned in $6-8{\mu}$ as usual manner, the tissues were stained in hematoxylin eosin, and examined hisopathologically. Follow results were attained 1. Pyknotic appearance of odontoblastic layer was noticed on the 1st week, and increased on the 2nd weeks, and it is appeared that degeneration and dearrangements of odontoblasts on the 4 weeks. But a little recovered on the 6th weeks. 2. The thickness of predentin layer was increased on the 2nd weeks, and increased remarkedly on the 3rd weeks and reached the maximum on the 5th weeks. 3. The interglobular dentin was appeared in spotty shape on the 2nd weeks, and increased on the 4th, 5th, weeks, and large amount of inter-globular dentin was appearanced on the 6th weeks. 4. It is appeared that enamel hypoplasia on the 4th weeks. 5. Epiphyseal and metaphyseal plate of tibia was increased from/on the 2nd weeks, increased maximumly on the 5th weeks. And pyknotic, dearrangements, and hyperchromatic appearances of chondrocytes on the plate were increased on the 1st week.

The flow around a foil with water jet was investigated using the two-frame PIV(CACTUS 3.1) system. After separation, unsteady recirculation & reattachment region was shown a result at reading edge. Separation area was decreased to 1/3 more by waterjet system with coanda effect. Angle of attack and water jet velocity was a variable in the experiment. Each parameters was controlled to $0^{\circ}\sim35^{\circ}$ and $0[m/s]\sim9.2[m/s]$. The separation of flow appearanced at first when the angle of attack is $17^{\circ}\sim18^{\circ}$, However, according to grew up of velocity, beginning of the separation was delayed. In this experiment, vortex and separation region was disappeared by blown when each parameters are low level, and separation controlled more certainly.
