Tomato (Solanum lycopersicum) is one of the most popular horticultural crops cultivated globally. Since the 1950s, the National Institute of Horticultural and Herbal Science (NIHHS) of Rural Development Administration (RDA) has been conducting research on developing Korean tomato cultivars. Recently, the objectives of breeding have been diversified according to the rapidly changing market trends. To meet such demands, various cultivars with distinct characteristics have been made: rootstock tomato, ornamental tomato, sweet cherry tomato, and virus resistant tomato. In 2022, a total of 20 cultivars were registered for variety protection in the Korea Seed and Variety Service (KSVS) and two cultivars with high temperature tolerance have been under field trials for application. In this paper, the breeding history and major characteristics of eight representative tomato cultivars are discussed. Since each tomato has its own valuable feature, they are expected to be used in diverse places from garden to farm.

The rapid development of biotechnology has increased the importance of microorganisms or their genetic information. Thus, the Nagoya Protocol on access to genetic resources and the fair and equitable sharing of benefits arising from their utilization was established, and countries are working to secure industrially and academically useful bioresources to deal with the agreement. In the case of Korea, because 67% of bioresources are imported from abroad, we are required to secure domestic bioresources as well. The number of isolated foodborne illness-causing microorganisms is predicted to invrease based on the incresing number of outbreaks of foodborne illness each year. Consequently, appropriate long-term preservation methods are necessary to secure the isolated microorganisms for the purpose of research and resourcification. Therefore, the long-term preservation methods for bacteria, fungi, viruses, and protozoa were investigated in this study, from domestic and international bioresource banks, and the functions of the cryoprotectants were reviewed and discussed. This review should be informative in the preservation of microorganisms and contribute to the development of biotechnology.

A field study was conducted to reduce airborne bacteria by supplying active ions to indoor spaces used by vulnerable human groups spending substantial amounts of time in places such as schools and hospitals. In an experiment conducted during school hours (8:00-15:00), the average number of airborne bacteria in classrooms was 345.53 CFU/m3 or more without active ions. However, ion supply reduced the airborne bacteria to an average of 113.23 CFU/m3, indicating an efficiency of 61.61%. As a result of tests in 33 rooms used for surgery in small and middle sized hospitals, ion supply for 2 to 4 hours reduced the average airborne bacteria concentration from 243.88 CFU/m3 to 104.34 CFU/m3, representing a 41.53% reduction. A laboratory test to confirm the ion activity has shown that the mortality rate of E. coli used as a test bacterium increased with exposure time to ions. The initial colony number of E. coli was 251 CFU, but decreased to 4 CFU after 60 minutes of exposure to active ions. Therefore, it was confirmed that the supply of active ions can contribute to the control of airborne bacteria in the indoor environment of schools, hospitals and other public facilities.

Fishery products play an important role in Korean food culture, and awareness of the safety of fishery products is increasing in the seafood market. Against this backdrop, Japan has announced a plan to release radioactive water to the sea from 2023. In the case of Korea, it is adjacent to the area to be discharged, so there are concerns about securing the safety of marine products. Therefore, it is necessary to analyze the change in perception and impact of marine product consumers due to the discharge of contaminated water and to study appropriate countermeasures when discharging contaminated water from nuclear power plants. In this study, the current status of radioactive contaminated water discharge in Japan was summarized, and a survey was conducted on the change in the consumption perception of marine products according to the discharge of contaminated water to analyze the factors affecting the consumption change of domestic consumers. According to the survey, 85.3% of the respondents said that it will affect the purchase of domestic marine products if Japan starts discharging contaminated water from nuclear power plants. Moreover, 85.5% of the respondents said it will affect the purchase of imported marine products.

Probiotic strain is known to regulate the immune system by colonizing in the intestine and interact with intestinal cell receptors of lymphoid tissue. In this study, safety of Streptococcus thermophilus KCTC14471BP and silk fibroin coating effects was evaluated with respect to mucin binding abilities and immune system modulation. S. thermophilus KCTC14471BP was coated with silk fibroin by adding 1% water-soluble calcium and 0.1% silk fibroin. S. thermophilus KCTC14471BP showed the high activities of leucine arylamidase and β-galactosidase. Regarding the antibiotic resistance tests, S. thermophilus KCTC14471BP was susceptible to ampicillin, vancomycin, gentamicin, kanamycin, streptomycin, erythromycin, clindamycin, tetracycline, and chloramphenicol. S. thermophilus KCTC14471BP coated with silk fibroin showed the improved mucin binding ability from 16.1% to 71.3% and was confirmed to have no cytotoxicity against RAW 264.7 macrophage. S. thermophilus KCTC14471BP coated with silk fibroin showed dose-dependently significant increases in pro-inflammatory cytokines IL-1β, IL-6, and TNF-α. These results suggested that S. thermophilus KCTC14471BP can be expected as a promising probiotic bacteria for applications to food industries such as fermentation or functional foods.

인삼은 다양한 국가에서 과거로부터 민간의약적으로 사용해 온 유용한 한약자원으로, 동북아시아와 북아메리카에서 서식하고 있다. 인삼의 학명은 Panax ginseng C. A. Meyer로 Araliaceae에 속하고 약용 부위는 곁뿌리를 제거한 뿌리 부분이다. 본 연구에서는 전세계에 분포하는 인삼의 종류와 명칭을 정리하고, 동북아시아 공정서 내 인삼의 기원들을 알아보았다. 다양한 인삼종의 전초의 형태를 비교하였고, 여러 문헌 정보를 바탕으로 각국 인삼종의 약리학적 효능을 정리하였다. 현재 한국에서 재배되고 있는 고려인삼의 품종은 약 15종이며, 이들 중 재래종(자경종), 천풍, 연풍, 금풍, 산양삼의 형태학적 특징을 비교하였다. 한약재 활용 가능한 인삼을 수확하기 위해서는 오랜 기간 재배해야 하며, 그 조건도 까다롭다. 약리학적으 로 가치가 있는 인삼종의 시장 수요를 충족하기 위한 대량증식 방법으로 기내조직배양이 활용될 수 있다. 따라서, 각 인삼종의 종자를 수집하여 크기를 측정하고 형태를 비교하였고, 종자를 횡단면으로 절단해 배의 형태를 관찰했다. 각 인삼종의 종자를 활용하여 기내배양을 진행하였고, MS+GA 1.0mg/L 조건에서 발아율은 미국삼이, 생존율은 금풍이 가장 우수한 것으로 확인 되었다. 인삼의 한 종류인 산양삼은 자연에서 성장 속도가 느리고, 재배조건이 까다롭다는 특징을 가지고 있다. 따라서, 산양삼을 수경 재배해, 해당 인삼종에서 발견되는 다양한 미생물종을 동정하였다. 기내배양을 통한 4종의 인삼종 종자 발아 실험에서도 다양한 미생물종이 확인되었고, rDNA 염기서열 분석을 통해 동정하였다. 본 연구는 한국한의학 연구원이 제공하는 전통의학정보포탈(KIOM Oasis Portal)과 농업진흥청 원예특작과학원의 인삼특작부에서 각 인삼종의 종자를 분양받아 진행되었 다. 해당 논문은 기내배양을 통한 인삼의 대량생산 체계 구축 연구의 초석이 될 것으로 사료된다.

Fisheries is known as a high-risk industry in Korea, and various efforts have been made to reduce occupational accidents. Trap fisheries represent crustacean production, accounting for 4.7% of total fisheries production and 10.7% of its production value, which is classified as a relatively high-risk industry. With the disaster insurance payment data of the National Federation of Fisheries Cooperatives (NFFC) from 2016 to 2020, the accident rate of the entire fishery, the accident rate of trap fisheries, and the type of disasters in the past five years were analyzed. As a result, the average fishery accident rate for the past five years was 5.31%, but it was high at 6.15% for coastal trap fisheries and 5.59% for offshore trap fisheries. Slips and trips, struck by objects and contact with machinery were the most common types of the accident according to the characteristics of the work, and hand injuries were analyzed the most. Additional efforts, including education for accident prevention, development of personal protective equipment and improvement of the working environment, are needed to prevent accidents caused by repeated types of disasters.
