2007년 양돈에서 먼저 시작한 HACCP(Hazard Analysis Critical Control Point, 위해 요소중점관리기준) 인증이 한우, 젖소로 확대되면서 금년 7월에는 양계농장에서 첫 인증을 받았다. 현재 HACCP는 포장육이 42.6%로 가장 많은 인증을 받았고, 가축사육.종축업 중 돼지 138건, 젖소 26건, 한우 20건, 닭에서 산란계 4건, 육계(육용종계 포함) 5건으로 총 9건을 이미 인증(2008.10. 15일 기준) 받았다. 이번 호에서는 산란계 부문(유통포함)에서 2호이자, 산란계 전업농가에서 1호로 HACCP 인증을 획득한 충남 아산 소재 계림농장을 소개하고자 한다. 계림농장은 아산시 지정 농특산물로 선정되기도 했고, 충남지역 최초로 무항생제축산물 인증을 받은 농가로 양계사업에서 선두적으로 발전하고자 노력하는 농장이다.

Conservation re-treatment of dagger and scabbard in Gyeongju National Museum, which were excavated from Gyerim-ro Tomb No. 14 (Treasure No. 635) was carried out after a wide-scale dissembling in order for publishing a report and holding a special exhibition. The interior shape of the iron dagger which was disclosed by ornament plates was confirmed by X-ray investigation. The results of XRF analysis which was used to analyse compositions of the golden ornament plates reveal that having more than 3% of copper distinguishes it from other Silla gold artifacts. The conservation treatment progressed in a way that surface contaminants were removed and insecure areas were consolidated. The original shape of the iron dagger and scabbard was found after adhering and restoration. With the ornament plates staying on the iron dagger, a stand in acrylic for display and storage was made, which is able to place the dagger and scabbard in the safest way.

This study was intended to provide management directions through the provision of tree spatial information as basic data for the preservation of Gyerim(legal historical site), which is located in Gyeongju city, Gyeonsangnam-do, Korea. As a result of the survey of the entire forest, there are a total of 25 species and 510 individuals growing trees. Of these species, 14 species are native and 14 are introduced species. Apart from Sophora japonica, Zelkova serrata, Celtis sinensis, most of the introduced species were adopted without historical basis after designation as a historical site. By a ratio of 36% to introduced species(including 3% of naturalized species; Ailanthus altissima), the historical heritage was significantly damaged. Gyerim, which has over 2,000 years of history, has a total 15 individuals(2.9%) large trees(over 100cm DBH). Ten of these are Salix glandulosa, and in the past, most of this area was considered a Salix glandulosa forest. Currently, however, there are many small trees(under 20cm DBH) for the next generation of growth and the Salix glandulosa forest will continue to decline. Furthermore, most small trees were afforested, so the historicity and place features as a mythological forest will quickly fade.

In most gold objects crafted using the granulation technique that have been thus far discovered in the Korean Peninsula, granules were joined using a soldering alloy of gold and silver. However, it was recently revealed through SEM-EDS analysis performed on the ornamented dagger sheath from Gyerim-ro Tomb No.14 in Gyeongju that the gold granules were joined to the surface of this sheath using an entirely different technique. The gold granules on the Gyerim-ro dagger sheath are evenly sized and shaped, the surface has a dendritic texture. Dendritic textures are a characteristic feature of metal alloys, not observed in pure metals. As a matter of fact, the gold granules were made of a ternary alloy of 77wt% Au, 18wt% Ag and 4wt% Cu. Due to this component, the alloy has a melting point below 1000℃ (approximately 980℃), which is significantly lower than 1064℃, the melting temperature of pure gold. This makes it possible to join the gold granules directly to the surface of the sheath by briefly heating them to high temperature, without the use of soldering or any other media. When examined through SEM image, the surface of the sheath showed no traces of soldering, it suggests that the granules were joined through unaided fusion.

요즘은 여름철 폭염 등의 외부환경으로 양계농가들의 생산성이 하락하는 시기이다. 닭의 고온스트레스가 극도에 달하며 체중 증가가 더뎌지는 등 폭염으로 가장 많은 피해를 보는 가축이기 때문에 고온기가 되면 계사 내 시설 환경의 중요성이 강조된다. 이에 본지는 최신식 설비로 사육환경 개선에 힘쓴 충남 부여 계림농장의 김오식 대표를 찾았다.
