The morphological and structural studios of Anisakinae larva has been carried out since Sept. of 1980. The larva were collected from naturally infested eleven swine of 1,531 examined at Kwang-Ju abattoir and from marine fishes, Somber japonicus, bought at Kwang-Ju fish market. The results observed were as follow : 1. Anisakis larva found in the stomach wall and on the surface of the mucosa were more or less degenerated. According to the progress of degeneration, the cross sections showed varied structures (Fig. 6, 7). 2. Size of the larva both from swine and fishes were measured respectively in average(mm); 18.0 and 18.7 in body length, 0.30 and 0.41 in body width, 1.64 and 1.68 in esophagus(muscular-part), 0.56 and 0.67 in ventriculus (glandular part), and 0.13 and 0.12 in tail. It was notable that body length of the larva in this present data, 18.0mm and 1.87mm, were shorter than those in previous dada, 24.3mm from human cases and 28.4mm from, however, the present data were almost similar to the data, 1.75mm, from swine case. 3. The Boring tooth, Mucron, long ventriculus and short round tail were observed in the larva of this present study. These structures were differentiated from Anisakis type II larvae which was provided with short ventriculus, and conical and tapering tall without mucron. 4. The ventricular appendix and intestnal caecum were not present in the larva. These might be differentiated from other Anisakidae larva such as Terranova larvae, Contracaecum larvae, Raphidascaris larvae and Thynnascaris larvae. 5. The findings through the histological observation were a pair of Y-shaped or butterfly-shaped lateal chords, ventral and dorsal chords, excretory(Renette) cell, high columnar epithelial cells of digestive tract and muscle cells. These morphological characteristics revealed varied features in the structures in the degenerative degree of the larva in the stomach wall. 6. The above-mentioned characteristics of the larva observed could be indentified as Anisakis type I larvae. 7. The reports on natural infestation of domestic animal with Anisakis type I larvae were two swine cases in Korea and Japan respectively, On the other hand two human cases of the larva were reported in Korea and more than one thousand cases in Japan. In Twiwan no reports of human and domestic animal cases could be found.

A stone mold from the Sabi period of Baekje was excavated at the western tombs in Neungsan-ri, Buyeo where there was a recent excavation survey (2016). It was believed and reported that such stone molds were used for copper needles during the early Iron Age; however, a close re-examination of the form revealed that they were used for bifid ornamental hairpins. Given its casting form, the stone mold of Neungsan-ri is estimated to have been used to make bifid ornamental hairpins in a ∩ shape, narrowing down toward the tip. It is considered an artifact of the Goryeo dynasty. The stone used to make the bifid ornamental hairpin mold of Neungsan-ri was chlorite-schist, the principal minerals of which include chlorite, amphibole, and talc. Similar rocks are in nearby Buyeo (Oesan-myeon), Cheongyang, Gongju, and Yesan. They are mainly found between Jiseon-ri, Oesan-myeon, Buyeo, Sucheol-ri, Yesane-up, and Yesan. Nearly 70 bifid ornamental hairpins from the Goryeo dynasty were excavated at Neungsan-ri, Buyeo and the surrounding areas. Among them, the bronze ones excavated from the tombs of Songguk-ri, Buyeo are estimated to have been made using this mold as they closely resemble the Neungsan-ri mold. Stone was likely the preferred material for molds to make bronze artifacts as it was easy to sink a die. Regarding the bifid ornamental hairpin cast excavated in Neungsan-ri, they obtained stones in nearby areas 20~50km from their location, made bronze artifacts, and distributed them to nearby sites during the Goryeo dynasty. These artifacts suggest that the casting technology of using a stone mold was still employed then.
