인공토굴(人工土窟) 숙성식품의 장기가공보관 수단의 원조로 자리 잡아, 광천옹암리 토굴이 전통식품 산업의 지혜와 관광산업의 역동으로 변신하고, 인공 굴은 폐광토굴에서 농산물저장을 위한 인공제작 굴의 활용기술로 이어져 산업화사회에 기여하고 있다. 대표적인 인공토굴중의 하나는 광천토굴이며, 마을뒤편 야산에 활석암으로 된 암반을 굴착한 토굴이다. 폭과 높이가 각각 2m 정도, 200여 m의 토굴 속에 수많은 젓갈을 담은 드럼통을 저장하여 숙성, 발효시킨다. 젓갈은 우리나라의 대표적인 수산발효식품이며, 어패류 등에 비교적 다량의 식염을 가해 자가소화효소 및 미생물분해 작용으로 알맞게 숙성되는 원리를 이용한다. 젓갈은 일종의 균 식품으로 식품을 발효시킴으로써 독특한 맛과 향 영양을 갖게 되며, 빵, 요구르트, 장류(간장 된장 등), 김치, 막걸리, 동동주, 식혜뿐 아니라 심지어는 버섯조차도 균 식품에 해당한다. 특히 어패류를 염장 발효시켜서 독특한 감칠맛이 나도록 한 우리나라 특유의 저장식품으로 예로부터 기호식품, 조미료 및 김치의 재료로서 널리 식용되어 왔던 양질의 단백질인 동시에 칼슘과 지방질 공급원이기도 하다. 최근에는 상품화된 자연친화적 농산물저장 굴로 사용되는 인공토굴도 등장하였다. 그것은 타공판과 흙을 이용한 생태환경지중건축물(生態環境地中建築物)로서 우리조상들이 오래전부터 지열을 이용하여 주거와 농산물을 저장하였던 재래식 토굴을 현대화시킨 구조물의 지중저장토굴 공간이다.

Many merchants have dealed in the salted shrimps(Saewoo -Jet) in Kwangcheon. They made the soil cave at headland on beach, so aged Saewoo-Jet in casks in soil cave with fitting temperature($13\~15^{circ}C$ and humidity($85\%$). Kwangcheon where it is gathering and scattering around the country have gained fame in its tastes and the freshness in Korea. Yu Myoun Won made the fresh starts Put it in this cave. Since 1949, the soil cave is used all the time. Ultimately this was getting warehouse business put the salted shimps since 1960. Today, this business is going down, and this warehouse is used for only the aged Period. As the alternative plan, many merchants focus on various fastivals, Saewoo-Jet special area plan, vessel improvement etc, and makes a wish to good sales. Folkway are Guldeagum-Je that they has done before digging the cave, Anteak(sods that care the family dwell in the house) and the October sacrifice have done on Gasin-Je in the soil cave. This cave has used as the refrigator when Saewoo-Jet come in the cave.

Effective storage facilities are required to stabilize the price of agricultural and marine products to preserve their qualities due to the big fluctuation of shrimp price in Korea. It is easy to make the cave because of good conditions of the land configuration, soil and convenient transportation. The cave storage can save the cost about 40% in building site and equipment, and about 50% in maintenance comparing to existing low temperature storage facilities. The cave storage provide to improve the quality of their stored products with the low heat conductivity, the constant temperature and humidity year round. Therefore, more low temperature storage facilities are required because the items are expanded from potatoes, sweet potatoes, onions, garlics, apples and chestnuts to tangerines, grapes, cabbages, radishes, and wet ginsengs. The demands of the low temperature storage facilities can be substituted into the cave storage facilities. Thus, studies are conducted to observe the changes of the components of the pure and the seasoned salted shrimps with fermentation period during stored at room temperature in cave and to establish the storing at underground facilities to produce high quality salted fish to make profit.

Microbial and nutritional characteristics of Kwangchun shrimp Jeotgal (salt-fermented shrimp) were assessed. Total mesophilic bacteria, coliforms, and S. aureus counts in Kwangchun shrimp Jeotgal were 3.48-5.42, 2.22-2.95, and 0.58-2.51 $log_{10}CFU/g$, respectively. Yeast and mold were detected only in Ohjeot (1.99 $log_{10}CFU/g$) and Yookjeot (1.47 $log_{10}CFU/g$). B. cereus, L. monocytogenes, Vibrio spp. and E. coli were not detected in Kwangchun shrimp Jeotgal, which contained abundant macrominerals (Ca, Mg, Na, K), with Na showing highest content. Palmitic acid content was higher than those of other saturated fatty acids. Eicosapentaenoic acid and docosahexaenoic acid contents were higher than those of other poly unsaturated fatty acids. Results showed Kwangchun shrimp Jeotgal is safe microbiologically with abundant nutritional components.

The main compositions of "Seokganju", a Korean traditional red mineral pigment, are iron oxides. To investigate its mineralogical and functional properties, we had got its ore from Juto cave in Ulreoung island, which was a famous field of it in Korean documents. The ore occurs as a paleosol between the olivine basalt and amphibole trachyte in discontinuously. It is reddish brown and yellowish brown and consists mainly of clay minerals with minor debris. Its reddish and yellowish brown color are due to the hematite and ferrihydrate, respectively. These iron oxides are precipitated as ferrihydrate from the ferrous water in the paleosol and partly changed to hematite. The color reproduced in timber by using seokganju pigment with traditional tools and methods is similar to that in heritage building. The moistureproofing and fire resistance of Ulreungdo seokganju is far better than that of artificial seokganju. Moreover, the combustion tests show that the artificial seokganju promote the ignition and combustion of the timber. Ulreungdo seokganju is regarded as a pigment with fungicidal efficacy because growth of two wood decay fungi (cov. and typ.) are inhibited in solid medium with it.

During the winter, the rice field-dwelling muddy loach Misgurnus mizolepis is buried in burrows constructed of mud and are subjected to exposure to air at times of shortage of water. To investigate the environmental factors that lead to changes of the skin mucus cells of the muddy loach in rice fields, we carried out an experiment where we artificially exposure the fish to air, duplicating as close as possible winter conditions in nature. During the summer, a water tank containing M. mizolepis was filled with mud, and the water was allowed to evaporate. After a month of evaporation, the loach constructed burrows similar to those in a winter rice field. The epidermis in the experimental fish was mostly occupied by large elongated mucus cells, whose numbers drastically increased in all observed regions of the dorsum, lateral region, and the occiput. Such features are typically seen in fishes in wild habitats during the winter season.
