국내에서는 한국저작권위원회 주관으로 디지털콘텐츠 식별을 위한 국가디지털콘텐츠식별 체계인 UCI(Universal Content Identifier)와 통합저작권관리를 위한 ICN(Integrated Copyright Number) 식별체계를 운영하고 있다. 그러나 UCI나 ICN은 국제표준 식별체계인 ISRC (International Standard Recording Code)나 ISWC(International Standard Works Code), ISAN (International Standard Audiovisual Number) 등과 같은 국제적인 표준 식별체계와의 연계가 되어있지 않다. 따라서 국내 콘텐츠의 해외시장 진출을 위해서는 해당되는 국제표준의 식별체계 와 연계를 위한 추가의 별도 작업이 요구되고 있으며, 외국에서 판매되는 콘텐츠에 대한 정산을 포함한 통계자료는 국내시스템으로는 통합관리가 불가능하다. 본 논문에서는 UCI/ICN과 국제 표준의 식별체계와의 연계를 위해 국내/외 식별체계 동향을 조사하고, 조사한 국제표준 식별체계 들의 메타데이터와 표준을 분석하여 UCI/ICN과의 연계 방안을 제시한다. 또한 시험 모형을 개발 해봄으로써, UCI/ICN과 국제표준 식별체계와의 연계방법에 관한 연구 방향을 제시하였다.

An experiment was conducted to evaluate the effects of nitrogen (N) level on the dry matter (DM) yield, N concentration and oxalate content of some tropical grasses, namely Rhodesgrass (Chloris gayana), Guineagrass (Panicum maximum) and Sudangrass (Sorghum vulgare). Three levels of N as urea were applied (Standard- 260, $Standard{\times}2$- 540 and$Standard{\times}4$- 1,060 kg N/ha for Rhodesgrass; Standard- 380, $Standard{\times}2$- 770 and $Standard{\times}4$- 1,570 kg N/ha for Guineagrass and Sudangrass) in a completely randomized design and grasses were harvested twice at approximately two-month intervals. Dry matter yield tended to be higher with increased rate of N fertilizer in all species, while further additional N ($Standard{\times}2$ or $Standard{\times}4$) did not significantly (p>0.05) further increase DM yield, when compared with the Standard level of N fertilizer application. There was also a trend towards higher N concentration in plants as N fertilization increased in all species and it was increased significantly in Rhodesgrass and Sudangrass (p<0.05 or p<0.01, respectively). Further additional N ($Standard{\times}2$ or $Standard{\times}4$) application showed no significant (p>0.05) differences on oxalate content in plant tissue within species, when compared with the Standard level of N. The Rhodesgrass contained 0.11, 0.13 and 0.15% soluble oxalate and 0.23, 0.25 and 0.27% total oxalate with Standard, $Standard{\times}2$ and $Standard{\times}4$ level of N application, respectively. The Guineagrass contained 0.54, 0.50 and 0.42% soluble oxalate and 1.60, 1.56 and 1.45% total oxalate with Standard, $Standard{\times}2$ and $Standard{\times}4$ level of N application, respectively. The Sudangrass contained 0.06, 0.15 and 0.12% soluble oxalate and 0.22, 0.22 and 0.21% total oxalate with Standard, $Standard{\times}2$ and $Standard{\times}4$ level of N application, respectively The results from this study suggest that these grasses do not use further addition of N fertilizer ($Standard{\times}2$ or $Standard{\times}4$) to form high content of oxalate salts, when compared with the Standard level of N. In addition, the levels of oxalate present with these grasses are quite low as far as toxicity to animals is concerned.

This study was conducted to investigate the dressing percentage and physicochemical characteristics, such as fatty acid composition, water holding capacity (WHC), shear force, meat color, cooking loss, and sensory evaluation, of experimental pork obtained from a total of 12 standard pigs and sows. The water content of tenderloin (73.38%) was the highest in standard pork (p<0.05). A statistically significant difference in crude protein content was shown between standard pork and sow pork (p<0.05). There were significant differences between standard pork and sow pork in shear forces of loin and tenderloin (p<0.01). There was a significant difference in WHC between standard pork and sow pork in loin, tenderloin, and hind legs (p<0.05). The CIE $L^*$ and CIE $b^*$ values of standard loin were significantly higher than those of sow loin (p<0.05). The CIE $a^*$ values of sow loin were significantly higher than those of standard loin (p<0.05). The contents of arachidonic acid for standard pork and sow pork were 0.33% and 0.84%, respectively (p<0.05). However, there was no difference in the total content of unsaturated fatty acid between the two groups. There were no significant differences between standard pork and sow pork after sensory evaluation, except for color and tenderness. The overall acceptability of standard pork was significantly higher than that of sow pork (p<0.05).

The effect of mixing ratios of active ingredient on the content uniformity of tablets was studied using caffeine as active ingredient and hydroxypropyl starch as diluent. In the case that caffeine content was not more than 1%, the standard deviation of individual tablet assays was inversely proportional to caffeine content. In the case of more than 1%, the standard deviation was constant independently of caffeine content. In the case that the designed tablet weight was not more than 200mg, the standard deviation of individual tablet assays was inversley proportional to tablet weight designed. In the case of more than 200mg, it was constant and the results for weight variation against the designed weight showed same tendency.
