This study was carried out to analyze deterioration characteristics of color-pigments painted Hanji to preserve and restore the cultural properties. On the traditional painting technique, glue was used with pigments in various ways for painting, but it eventually caused the deterioration of paintings. Thus, five colors were selected and analyzed for this study for investigating their characteristics of deteriration. Three kinds of glues (Wugyo, Nokgyo, and Togyo) and two kinds of pigments (Chinese and Gilsang) were painted on the Hanji for the accelerated aging test. And then color fastness of pigments and tensile strength of painted Hanji were measured for the estimation of deterioration degree. The results of SEM-EDS showed that Chinese pigments including blue, yellow, green, and red were composed of inorganic substances but the brown was organic substance. Gilsang pigments were composed mainly of Si and Ti ions. Color fastness of the Gilsang pigment blue, yellow, green, and brown were better than those of Chinese. Chinese pigment brown with organic substance showed the worst color fastness. Generally, Chinese pigments painted Hanji showed higher tensile strength than Gilsang in the accelerated aging test. Hanji treated with Chinese pigment and Nokgyo (antler glue) blends and Gilsang pigment and Togyo (rabbit pelt glue) blends showed higher tensile strength than the others. And Andong Hanji showed the highest tensile strength.

Once of recent issue in the leather industry is disposal of shaving scrap containing chromium. Shaving scrap is indispensible generated by control of the final thickness in the leather making process. It is the flesh layer of the skin consisting mainly of collagen. More recently, we have tried to improve the quality of the isolated gelatin. The purpose of this research was to extract gelatin for agricultural usage. As a result, it does not contain Cr and could obtained to a good gelatin that have more than 130,000Da. average molecular weight, more than 30 mps viscosity and more than 100g jelly strength. Gelatin that is extracted by alkaline condition expected to be available to high performance gelatin such as material of organic fertilizer(ex, Nitrogen-release fertilizer).

This study is consider·ed about the relation or costume among Parhae, ancient Japan and Tang and the culture of this time commonly was influenced by Tang;s culture. The recorded items, which were exchanged from Parhae to Tang and ancient Japan, are the pelt of marten, seal, bear and tiger skin or Ammowhaha(암모화) Gu(구) and so on. Other items from Tang and ancient Japan to Parhae are various clothes and material like silk and so on. This Parhae's clothes made with leather obtained through hunting were the main product of Parhae and had been greatly famous in Tang and ancient Japan. At that time, Tang and ancient Japan had been only dependent on the agricultural life but had not been accustomed to the hunting life, and thereupon, the people in Tang and Nara Era had difficulties to get leather clothes. Accordingly, the leather products stood for the rich, and the people who purchased the leather products from Parhae were recognized as the rich. On the other hand, The prince and the royal family in Parhae were dispatched to Tang as Sooktwui(숙위). They paid a tribute to Tang and In return for it, Tang gave to Sookwui as well as to Parhae's envoys various items and clothes such as Po(포), belt(대), gold and silver Eodae(어대) and textile like a type of silk. These clothes were considered as the formal uniform like Kwanbok(관복) of Parhae. Specially, the time when Sookwui was sent to Tang rot-responded with the time when Tang gave formal uniform to Parhae's envoys. Therefore, we can confirm that the sending of Sookwui influenced to form uniform system of Parhae. In this exchange relation, there were several duplicated items showed, for example Po(포)-belt(대), Eui set(의일습), Eoeui(어의), Jobok(조복), Go(고). These items in Parhae were appeared in process of exchanging from Tang to Japan and from Tang to Parhae. At that time, the exchanges between Tang and Parhae were frequently active much more than those between Tang and Japan, and the acceptance of the culture from Tang was easier in Parhae than Japan in consideration of the geographical location. Therefore, those clothes could be understood as the items already used in Parhae and affected from Tang. These items in Parhae were appeared in process of exchanging from Tang to Japan and from Japan to Parhae. As a result, it is expected that the costumes, which Parhae took from Japan, are the same as those of Tang.

Radioactive iodine has been widely used in patients with thyroid cancer combined with surgical treatment. However, due to individual variations in absorption and excretion and uptake by tumor tissue of radioactive iodine, there are differences in therapeutic effect and adverse effects even if the same doses are administrated. So this study compared the therapeutic effect and radiation hazard by measuring internal radiation dose. Of total 27 patients with well differentiated thyroid cancer who had been thyroidectomized, we administered radioactive iodine 100 mCi, 150 mCi, 200 mCi. According to BEL DOSIMETRY PROTO-COL, beta and gamma ray dose were estimated from a pelt of the logarithm of the percent of dose per liter of whole blood versus day, and percent dose retained versus day using somilogarithmic paper, respectively. 1) Physical dose to whole blood averaged $56.54{\pm}13.02$ rad in 100 mCi administered group, $76.83{\pm}19.97$ rad in 150 mCi administered group, $95.08{\pm}25.51$ rad in 200 mCi administered group and there has been a significant correlation among the groups. 2) Mean percent dose retained 48 hours later was 26.34%. 3) There was no significant correlation of physical dose between absence and presence of metastasis. 4) 17 of 19 patients who has been followed up with TSH and serum throglobulin, Thallium scan were successfully ablated by radioactive iodine. 5) Leukocyte, lymphocyte, neutrophil, platelet counts all deelined in 4.6 weeks and most of all were restored 3 months later. 6) There was no significant correlation between physical dosimetry and biologic dosimetry. Generally administered doses of radioactive iodine (100-200 mCi) to patients with thyroid cancer postoperatively had developed transient bone marrow suppression and minimal chromosomal aberration, but they were within safety dose to blood (200 rad). And there has been no significant differences in residual dose 48 hours later between Korean and western people.
