This study attempted to research the local food of various regions at a personal level by discovering how food has developed das part of a region's culture base. Discovery of the characteristic story behind the making of a region's characteristic food as local delicacies can inspire self-esteem in the culture, and enhance the real-life image as appropriate to a region, and thereby be made a part of local tourism and thus contributing to the local economy. For this reason, the native foods of the region of Chungcheongnam-do were researched in terms of the cultural sensibilities that inform the unique history of that region. The study was designed so as to aid in understanding food's characteristic value in Chungcheongnam-do and to give a historical representation of Chungcheongnam-do's image by means of storytelling techniques; thus, the local food's character can be presented alongside a story that appeals to the five senses. For this purpose, Chungcheongnam-do's representative native rice table was cast as the 'Hyunchoong rice meal table' - after the figure of admiral Yi Sun Shin of Asan area region, a representative image of Chungcheongnam-do - and 'Choosa rice meal table', after the figure of 'Choosa' Kim Jeong Hee of Yesan region, of which various literary works form a representative image of Chungcheongnam-do. 'Hyunchoong rice meal table' was composed of a health food centered menu which could supply sufficient nutrition as a food ration in times of war or winter shortage, thus providing an image of nutrition and power as appropriate to these situations. Also, to assess the health effectiveness of each rice table, the functionality of the ingredients were investigated as reported in 'Sik-ryo-chan-yo : a dietary treatment' which was published by Soon-Ui Cheon in the Chosun era and by which the foods of the early Chosun era won recognition as being both healthy profitable.

Background: The risk of imported infectious diseases has been increasing with the annual rise in the number of international travelers. Objectives: This study aims to analyze the distribution and characteristics of intestinal bacteria isolated in 2019 from residents of Chungcheongnam-do Province with experience of travelling overseas. Methods: Twenty-three former overseas travelers with diarrhea were analyzed to detect viruses and bacteria according to the Manual for Detection of Foodborne Pathogens at Outbreaks. Additionally, antibiotic susceptibility tests and 16s rRNA sequencing were performed. Results: Twenty-five strains of ten pathogens were isolated from 18 samples. Pathogenic E. coli was the most common at 57.7%, followed by Clostridium perfringens (15.4%), Campylobacter spp. (7.7%), and Salmonella spp. (7.7%). The serotype of Salmonella was confirmed as Salmonella Braenderup, II 9,46:g,[m],[s],t:[e,n,x]. Conclusions: It was confirmed that the major enteric bacterial pathogens isolated from overseas travelers in Chungcheongnam-do Province were pathogenic E. coli, as found in other studies. The study on Plesiomonas shigelloides is meaningful in that it is reported as a rare case of infection in Korea. Antibiotic resistance and 16s rRNA analysis were performed, which is expected to provide important basic data for the prevention of traveler's diarrhea.

This study aimed to determine the most suitable coir substrate mixing ratio for optimizing the growth and yield of the "lpduelkkae 1" cultivar. We comprehensively analyzed the physicochemical properties, growth, and yields of four different substrate combinations: perlite (coir with mixing ratios of 70:30 (PC30), 50:50 (PC50), and 30:70 (PC70)) and 100% coir (C100). The results revealed substantial differences in substrate properties. C100 exhibited the highest total porosity and the lowest solid phase, indicating excellent air permeability. The pH levels and electrical conductivity (EC) values ranged from 5.4-6.8 and 1.2-3.1 dS·m^-1, respectively. Leaf growth parameters, including length, width, and dry weight, showed positive correlations with high coir ratios, except for PC30. PC70 and C100 outperformed other substrates in stem growth, exhibiting superior stem diameter and fresh and dry weights. The quantity of marketable leaves was the highest in the C100 substrate. Furthermore, C100 comprised integrated levels of essential nutrients, such as Ca and Mg, owing to its high coir content. In conclusion, a coir ratio of approximately 70% (v/v) should be maintained in the substrate for creating an optimal cultivation environment. Furthermore, the selection of humidity-resistant varieties as well as precise nutrient and moisture management for different seasons and growth stages are crucial for a successful perilla leaf hydroponic cultivation.

본 연구는 2020년 10월 중 충청남도내 단체 급식소에서 발생한 대규모 집단 식중독 원인에 대하여 분석하였다. 전체 급식원 135명 중 21명(15.6%)에서 음식을 섭취한 후 1시간 이내에 주로 매스꺼움과 구토 증상을 보였다. 유증상자 21명 중 11명과, 조리종사자 1명, 조리기구 2건과 보존식 8건에서 B. cereus가 검출됨에 따라 B. cereus에 의한 집단 식중독으로 판단하였다. 분리된 21개의 균주를 PFGE 분석한 결과, 19개의 균주가 동일한 것으로 판단되었고, 이들 균주가 가지고 있는 독소 유전자는 CER, nheA, entFM이었다. 실험결과, CER을 포함하고, 증상 발현 시간이 1시간 이내로 매우 짧아 B. cereus의 구토형 식중독으로 판단하였다. 집단식중독 원인으로 안전하지 않은 급식환경과 제대로 관리되지 않은 음식에 의한 것이라 조사되었다. 이러한 결과는 단체급식에서의 급식환경과 제공되는 음식이 철저하게 관리되어야 한다는 것을 보여준다. 이와 더불어 보존식에서 원인 병원체를 찾아내는 것은 식중독의 원인을 추정하는데 매우 중요하므로, 집단급식소에서 규정에 맞는 보존식 용기를 이용하여 이를 적정온도에 잘 보관해야한다. 또한 정밀한 식중독 역학조사를 기반으로 사례를 분석하고 결과를 전파함으로써 유사한 식중독이 재발하지 않도록 해야 한다.

This study is to analyze location conditions for erosion control dams to be constructed in Chungcheongnam-do, Daejeon Metropolitan City, Chungcheongbuk-do and Gyeongsangbuk-do in order to establish proper conditions for erosion control dams in the future. 199 sites where erosion control dams are expected to be built in 2010 were chosen and investigated in terms of 12 factors including basin area, basin slope, and landslide risk. The results showed that erosion control dams for Chungcheongnam-do and Daejeon Metropolitan City are mostly impermeable gravity dams mainly composed of concrete. In contrast, Chungcheongbuk-do and Gyeongsangbuk-do are increasing the number of permeable or compound erosion control dams. Basin analysis at planned erosion control dam sites showed that at least 44.5% of the total area has high landslide risk. Gyeongsangbuk-do had the largest basin area for erosion control dam sites at 157.3ha, followed by Chungcheongbuk-do at 64.4ha and Chungcheongnam-do at 54.8ha. Analysis of sand deposits in the Chungcheongnam-do erosion control dam built in 2010 confirmed an average deposit of 971.8m3. The sand deposit capacity and amount of sediment control for erosion control dams have a very low correlation with basin area or flow path slope, and this needs to be addressed in future sand deposit capacity designs.

Objectives: This study was performed to analyze cases of food poisoning outbreaks reported in Chungcheongnamdo Province in 2019 and report it as effective data for preventing food poisoning in the future. Methods: Food poisoning outbreaks were analyzed to detect virus, bacteria, and protozoa according to the Manual for Detection of Foodborne Pathogens in Outbreaks to clarify the causes of food poisoning that occurred in Chungcheongnam-do Province in 2019. Results: Among the 79 cases of food poisoning outbreaks, 59 cases (74.7%) were in general restaurants, 15 cases (19.0%) in food service institutions, three cases at banquets, and two cases in take-out food. The 42 cases at general seafood restaurants made up the majority of food poisoning in Chungcheongnam-do. Food poisoning pathogens were shown in 13 cases (86.7%) out of the 15 cases at food service institutions, and 10 cases were related to Norovirus. Among the 79 cases, food-borne pathogens were identified in 35 cases of outbreaks, accounting for 44.3%. The confirmed pathogens were as follows: bacteria (24 cases), Norovirus (12 cases) and Kudoa septempunctata. (five cases). The food-borne bacteria were pathogenic E. coli (12 cases), Staphylococcus aureus (six cases), Salmonella spp. (two cases), Campylobacter jejuni, Bacillus cereus, Clostridium perfringens, and Vibrio parahaemolyticus (one case). Conclusions: To prevent food poisoning, it is necessary to analyze regional characteristics and environments and to hold a campaign for the prevention of food poisoning based on that analysis. In addition, when food poisoning occurs, the results of analyzing its cause and spread based on accurate epidemiological survey need to be shared.
