Humankind history is faced with one gigantic turning point due to development of Living genetically Modified Organisms. Food production by means of LMO is on the acceleration in an effort to solve the shortage of food problems. Food is also used as alternative energy source. Use of LMO product is not only limited to food and energy, but is actively utilized in various fields of medicines. This paper is first to check out the state of biomedicine developed and associated problems from industries that use LMO, after which we made an attempt on legislative approach to find out means of relief, through examples of such laws legislated for the sufferer from the adverse effect of the biomedicine. As for the liable subject to bear the responsibility for compensatory damage in a way of relieving the victim owing to adverse effect of biomedicine, those who manufactured and sold biomedicine and who are related to the damage to the victim due to the accident and medical doctors and pharmacists who prescribe and administer the medicine in question have been looked into. Accidents involving medicines and medical supplies could take place without reason for imputation on part of the liable subjects or fault of the victim, in which case the victim can't receive damage compensation from any of both parties. When such accidents happened turn out to be no fault accidents, introduction of damage relief measures might have to be reviewed against side effects of medicine and medical supplies as no fault compensation in order for actual relief to be possible. Talking about technicality of legislation, we can suggest a method of strengthening the accountability of manufacturer for stereotypical agenda on biomedicines by newly legislating special regulation with an issue that resists claim on risks associated with the development of medicine and incorporating the same into Manufactured Product Liability Law. After all, when an accident happens associated with biomedicine, the damage will be done to the consumer. And the consumer will be exposed to fatal danger even without the time to cope with potential risks associated with medicine and medical supplies they take. Therefore, it is necessary to protect the potential victim by having the manufacturer of biomedicines bear the liability of medical risks.
There are concerns about the environmental release of living modified organism (LMO) maize created to increase yields. In fact, there are cases in which LMO crops for feed have been leaked in Korea to form autoite colonies, and concerns about LMO spill are intensifying. In this study, the possibility of environmental outflow and occurrence of native organisms was analyzed using maize feed and seeds distributed in Korea. In the evaluation of the possibility of spontaneous occurrence of maize in the event of an unintentional release of maize feed made by crushing maize, the incidence rate of maize was 0.01%, which was extremely low compared to the germination rate of maize seeds. A survey of the dormant rate of maize showed that all maize seeds collected every month were dead. In the germination rate test by temperature using Daehak wax corn and Kwangpyeongok, high germination rates were found at 20℃ and 30℃, and relatively low germination rates were found at 10℃ and 40℃. In addition, all germination tests showed a higher germination rate Daehak wax corn than Kwangpyeongok. The difference between domestic and overseas cultivation maize was confirmed through a survey on the agricultural properties of three varieties of maize. The data obtained through this experiment could be the basis for the evaluation of the weediness potential of environmental risk assessment and technology to suppress the occurrence of autoite in preparation for future LMO spills.

With the increasing development and commercial use of genetically modified maize, it is essential to develop an appropriate method for detection of individual LMO (Living modified organism) events for monitoring the samples. In South Korea, commercial planting and accidental or unintentional releases of LMOs into the environment were not approved. In this study, to increase the efficiency of LMO detection, we developed simultaneous detection methods for 11 LM maize events. This multiplex PCR detection method is economical, as it saves time, cost and labor. We developed 11 individual LM maize events, and applied 4 multiplex PCR sets to the LM maize samples. These results are confirmed by applying the multiplex analysis of LMO environmental monitoring from 2012 to 2014, which represents the unintentionally released LM maize samples. The data were correlated with event specific PCR results. Our results indicate that the multiplex PCR method developed is suitable for detection of LM maize in LMO monitoring.
Reciprocal hybrids between the mud loach ($Misgurnus$$mizolepis$) and cyprinid loach ($M.$$anguillicaudatus$) were produced by artificial fertilization. The chromosome number of mud loach was 2n=48, consisting of 12M+4SM+32A chromosomes. The cyprinid loach has 2n=50, consisting of 10M+4SM+36A chromosomes. The chromosome numbers of the diploid reciprocal hybrids were 2n=49, consisting of 11M+4SM+34A chromosomes. All the karyotypes documented in this study had the same arm number of 64. There was no evidence of chromosomal polymorphisms or sex-related heteromorphism. The cytogenetic traits of the hybrid genotypes were intermediate between those of the parent species. In all genotypes, the chromosomal NORs localized to the terminal short arms of the same metacentric chromosome pair. These results suggest that Robertsonian translocation occurred between metacentric chromosome 1 of mud loach and acrocentric chromosome of cyprinid loach.
A 26 day experiment was conducted to determine the effects of feeding and starvation on the survival, morphology, and histology in chum salmon (Oncorhynchus keta) fry. We included three experimental groups: starved, fed, and initial. The survival and growth rates were lower in the starved group than in the fed group (P < 0.05). In the starved group, survival began to decline after 16 days, and all fish had died after 26 days. We determined the effects of starvation on the morphometric parameters using the truss and classical dimensions. The dimensions in the head region were larger in the starved group than in the initial and fed groups. In contrast, the truss dimensions of the fed group were larger than those of the initial and starved groups. Starvation reduced the heights of the hepatocyte nuclei and of the intestinal epithelium (P < 0.05). The starved group also showed atrophy of the digestive structures and shrinkage of the foregut and midgut. Starvation led to the degeneration and atrophy of the exocrine pancreas, in which the lumen was markedly diminished and the folds of mucosa were less apparent. The hepatocyte morphology in the starved group was abnormal compared with that of the initial and fed groups, with highly compact, irregularly shrunken nuclei. Melanomacrophages were randomly distributed in the kidneys of the starved group, and their abundance increased rapidly during the experiment. In contrast, neither the initial nor fed group had any melanomacrophages. These results suggest that the nutritional parameters used in this study are useful indices of nutritional status in chum salmon.
In nature, plant diseases, insects and parasites (hereafter called as "pest") must be co-survived. The most common expression of co-survival of a host crop to the pest can be tolerance. With tolerance, chemical uses can be minimized and it protects environment and sustains host productivity and the minimum pest survival. Tolerance can be applicable in all living organisms including crop plants, lifestocks and even human beings. Tolerant system controls pest about 90 to 95% (this pest control system often be called as horizontal or partial resistance), while the use of chemicals or selection of high resistance controls pest 100% (the most expression of this control system is vertical resistance or true resistance). Controlling or eliminating the pests by either chemicals or vertical resistance create new problems in nature and destroy the co-survial balance of pest and host. Controlling pests through tolerance can only permit co-survive of pests and hosts. Tolerance is durable and environmentally-friend. Crop cultivars based on tolerance system are different from those developed by genetically modified organism (GMO) system. The former stabilizes genetic balance of a pest and a host crop in nature while the latter destabilizes the genetic balance due to 100% control. For three decades, the author has implemented the tolerance system in breeding maize cultivars against various pests in both tropical and temperate environments. Parasitic weed Striga species known as the greatest biological problem in agriculture has even been controlled through this system. The final effect of the tolerance can be an integrated genetic pest management (IGPM) without any chemical uses and it makes co-survival of pests in nature.in nature.
Since the recent COVID-19 pandemic, countries have been strengthening trade protection for their security, and the importance of securing strategic materials, such as food, is drawing attention. In addition to the cultural aspects, the global preference for food produced in Korea is increasing because of the Korean Wave. Thus, the Korean food industry can be developed into a high-value-added export food industry. Currently, Korea has a low self-sufficiency rate for foodstuffs apart from rice. Korea also suffers from problems arising from population decline, aging, rapid climate change, and various animal and plant diseases. It is necessary to develop technologies that can overcome the production structures highly dependent on the outside world of food and foster them into export-type system industries. The global agricultural industry-related technologies are actively being modified via data accumulation, e.g., environmental data, production information, and distribution and consumption information in climate and production facilities, and by actively expanding the introduction of the latest information and communication technologies such as big data and artificial intelligence. However, long-term research and investment should precede the field of living organisms. Compared to other industries, it is necessary to overcome poor production and labor environment investment efficiency in the food industry with respect to the production cost, equipment postmanagement, development tailored to the eye level of field workers, and service models suitable for production facilities of various sizes. This paper discusses the flow of domestic and international technologies that form the core issues of the site centered on the 4th Industrial Revolution in the field of agriculture, livestock, and fisheries. It also explains the environmental awareness production technologies centered on sustainable intelligence platforms that link climate change responses, optimization of energy costs, and mass production for unmanned production, distribution, and consumption using the unstructured data obtained based on detection and growth measurement data.

As the social and economic value of living modified organisms (LMOs) increase, so do the potential risks they pose to humans and the environment. Therefore, all laboratories using LMOs must establish an LMO laboratory in accordance with the standards required by regulations. Recently, in high school, LMO-related experimental programs have been developed for their educational effects. Also, in this case, it is necessary to comply with the regulation for LMO laboratories. However, high schools are still unfamiliar with the LMO laboratory, and it is difficult for teachers to manage an LMO laboratory because its implementation applies the same standards to general research institutes. In this study, we used causal chain analysis to discover the difficulties each teacher faced while setting up an LMO laboratory by examining three cases. The difficulties experienced by teachers are as follows: the first problem is "reluctance to set up an LMO laboratory," because of "administrative tasks for laboratory registration" and "difficulty in persuading colleagues." The second problem is a difficulty for teachers to operate LMO laboratory in blind spots, due to "inflexible installation and closure," "medical waste disposal," and "LMO education that does not fit the school context." Through this study, although the difficulty of running an LMO laboratory is caused by a lack of necessity and insufficient consideration of the school context, the more fundamental cause was a lack of collaborative planning between the educational field and the operating institutions. The teachers who participate in this research suggest that "using shared LAB" and "preparing opportunities for knowledge sharing" can be considered as strategies for operating the school's LMO laboratory. We feel that this study will provide a useful reference for teachers or schools planning to build an LMO laboratory.
Living modified (LM) crops are imported each year to South Korea as food and feeds, LM canola being one of the imported crops. The cultivation of LM crops is not permitted in South Korea but the import of these crops is increasing. In this study, we surveyed the environmental risk of imported LM canola at 9 provinces, from March 2009 to June 2013. Monitoring of canola was conducted around feed factories, roadsides, harbors, farmhouses, and flower festival regions. From the total of 595 canola samples collected from 1850 monitoring sites, we identified 6 LM canola samples. The LM canola samples were subjected to protein and DNA based analysis. PCR analyses using approved 5 single event primers (T45, MS8, RT73, Rf3 and Topas 19-2) revealed that two crops were glyphosate-resistant LM canolas, and four were glufosinate-resistant LM canolas. This study suggested that environmental monitoring is a useful research tool to manage LM crops unintentionally introduced into the environment in South Korea. This result can be used as a basis for future post-management of canola crops.

We describe early morphological development in laboratory-reared specimens of the brown croaker, Miichthys miiuy, in relation to fin differentiation, head dimensions, and squamation. From the yolk sac stage to the flexion larval stage (a period of 12 days following hatching, at which time the larvae were <4.2 mm in total length; TL) we observed the presence of a fin-fold around the body, while the caudal fin appeared rounded and lacked scales. Rays developed in the dorsal, anal, and pectoral fins in a process that was almost complete in larvae 12 days, while ray segmentation occurred between 26 and 29 days of age. Elongation of the middle rays of the caudal fin was initiated at 32 days, and the rays were remarkably elongated by 37 days. By 68 days the caudal fin was lanceolated (50.7 mm TL). Scales began to develop from the midlateral lines of the caudal peduncle at 9.1mm TL (28 days), eventually encompassing the entire operculum (22.1 mm TL; 44 days). The head dimensions were largely stabilized at >12 mm TL (30 day).
