        The National R&D Innovation Act emphasizes the improvement of the quality of R&D activities. The research institute is making efforts to improve the quality of research and effectively manage research implementation. KINAC has conducted various R&D projects regarding nuclear nonproliferation and nuclear security, and their scope and scale have been gradually more widened and increased. It consequently becomes important how to successfully manage research projects and ensure their qualification with the growth and complexity of research in KINAC. Unfortunately, no attempt was made to introduce and apply project management methodologies. Therefore, the objective of this study is to introduce project management standards and guidelines as an initial step towards improving the overall research quality of the institute. Project management is the well-organized application of knowledge and techniques to efficiently and effectively initiate, plan, control, and close projects, in order to achieve specific goals and meet success criteria. There are some guidelines regarding project management, including PMBOK (the Project Management Body of Knowledge), PRINCE2 (Projects in Controlled Environments), ISO 21500 (Guidance on Project Management), and PMP (Project Management Professionals), etc. They are international standards that consist of processes, guidelines, and best practices for project management. They provide structured processes and approaches to plan, execute, monitor, control, and complete projects. By reviewing the guidelines, the commonly important factors, including schedule, cost, quality, resources, communication, and risk management were introduced to apply to KINAC R&D project implementation. In addition to the management standards, systematic efforts are also continued to enhance the R&D qualities of the institute. These efforts include the implementation of a quality management system (ISO 9001:2015), development of an integrated research achievements management system, regulation development, and distribution of guidebooks for project managers and researchers. These efforts have been evaluated as improving the quality of the research.

        ISO 9001:2005 is the international standard for implementing a Quality Management System (QMS), which provides a framework and principles for managing an organization’s quality management. The aim is to ensure that the organization continuously provides products and services that satisfy regulatory requirements. The “process approach” in ISO 9001 is defined as a systematic method of achieving organizational goals by comprehending and managing the interconnected processes as a cohesive system. Recently, KINAC has decided to develop standard processes in the field of R&D and performance management based on the framework of the ISO 9001:2015 quality management system. The objective of this study is to establish standardized processes for conducting research and development, as well as managing the outputs and performance of R&D activities. It involves identifying, designing, implementing, monitoring, and continually improving processes to ensure consistency, efficiency, and effective management of KINAC R&D and its achievements. Firstly, R&D and the research performance management process were defined, and the processes were categorized by function according to the requirements of ISO 9001:2015. Second, the ISO 9001 requirements were compared to the institute’s existing regulations and documents in order to identify any additional processes and procedures needed to meet the quality management requirements. Finally, the lists of quality documentation were determined for the institute’s QMS. As a result, a total of 30 QMS documents were listed, including 1 manual, 12 quality processes and procedures, and 17 quality instructions. The documents can be categorized into four process groups: the management and planning process group, the R&D and achievements management process group, the analysis and improvement process group, and the support process group. All input and output information of each process are connected and interrelated. The implementation of quality management standards and procedures for R&D in KINAC could lead to improved research practices, more reliable data collection and analysis, and increased efficiency in conducting R&D activities. For further study, it is planned to create detailed, high-quality documents that adhere to standard requirements and guidelines.

        Since the National Research and Development Innovation Act. was enacted, evaluation and management of research outputs become more important. The research output is defined as all types of information resources produced from the scientific research activities in each research phase, such as learning, proposing, performing, and publishing. Among them, research outputs mainly from the publishing phase have been systematically managed, including articles, books, technical reports, patents, and software. KINAC, like other Korean R&D institutions, has also achieved growth in research outputs, through continuously increased investment in R&D projects. However, R&D productivity, technology transfer, and commercialization remain low level. The importance of R&D performance diffusion has been emphasized. It’s because the creation of economic value through the utilization of research results has been emerging as a key issue in R&D policy. Therefore, various policies are being nationally pursued to promote the utilization of research achievements, but the results are not being effectively utilized and disseminated. In the field of nuclear nonproliferation and security, it is also difficult to diffuse the R&D performance. In this study, the research outputs of KINAC from 2010 to 2021 were analyzed. A number of research outputs have been made and managed, but the R&D performances have not been analyzed and identified yet. In addition, supportive methods were suggested for efficient performance management toward diffusion. For this purpose, some policies of Korea and other countries concerning performance diffusion -related policies were reviewed. The best practices of performance management and applications were also reviewed and compared to the KINAC cases. As a result, the number of research output has dramatically increased during the last 10 years, showing an average annual total output of 84 and year-on-year increase of 18%. The biggest change was in the conference papers and journals, whereas, there were no trends by year in the case of the technical reports and patents. Of course, it was proportional to the size of the organization, the number of research projects, and its budget. Because many studies highlight the importance of institutional resources, capabilities, and processes for performance management as factors affecting efficient diffusion, the current status of our process was also identified. This study is expected to be applied to the improvement of the performance management of the institute, leading to the enhancement of the R&D performance application.

        This study assessed effective strategies to reduce the sodium intake among consumers using pork cutlet sauce as a model food system. Original pork cutlet sauce and sodium-reduced sauce (29% reduced by a salt substitute) were analyzed to characterize the sensory properties using descriptive analysis. The effects of sodium-reduction of the sauce, consumer type (nutrition teachers vs. general consumers), information related to the sodium content, serving method, and consumer’s health, taste and sodium-related attitudes on the consumer’s preference, perception, and intake of the sauce were analyzed using a consumer test. In descriptive analysis, the original and sodium-reduced sauce showed similar sensory characteristics but did not differ in saltiness. In the consumer test, there were no significant differences in the overall preference levels between the two sauces. On the other hand, there were significant differences in preference and perception between nutrition teachers and general consumer groups, which were due largely to their age as well as the health and sodium-related attitudes and nutritional knowledge differences. Sodium-reduced information decreased the perceived saltiness intensity. In addition, reducing sodium intake by serving pork cutlet sauce in a bottle can be an effective strategy because this serving method increased the acceptance and induced the smaller intake of sauce.

        Mitochondria participate in various intracellular metabolic pathways such as generating intracellular ATP, synthesizing several essential molecules, regulating calcium homeostasis, and producing the cell’s reactive oxygen species (ROS). Emerging studies have demonstrated newly discovered roles of mitochondria, which participate in the regulation of innate immune responses by modulating NLRP3 inflammasomes. Here, we review the recently proposed pathways to be involved in mitochondria-mediated regulation of inflammasome activation and inflammation: 1) mitochondrial ROS, 2) calcium mobilization, 3) nicotinamide adenine dinucleotide (NAD+) reduction, 4) cardiolipin, 5) mitofusin, 6) mitochondrial DNA, 7) mitochondrial antiviral signaling protein. Furthermore, we highlight the significance of mitophagy as a negative regulator of mitochondrial damage and NLRP3 inflammasome activation, as potentially helpful therapeutic approaches which could potentially address uncontrolled inflammation.

        Four sympatric tortricid (Lepidoptera) species in New Zealand, Epiphyas postvittana (Walker), Planotortrix octo (Dugdale), Cydia pomonella (L.), and Cydia succedana (Denis and Schiffermüller), were studied for the morphology of antennal sensilla and the chemical communication systems using scanning electron microscopy (SEM), electro-antennogram (EAG), gas chromatography-electroantenno-detection (GC-EAD), single sensillum recording (SSR) and field tests. Antennal flagella of adult have four main types of olfactory sensilla (s.); s. trichodea, s. basiconica, s. auricillica, and s. coeloconica in the four species. The s. trichodea subtype I was longest and male-specific in all the species. The antennae of males of the four species showed characteristic higher EAG, GC-EAD and SSR responses to 12, 14-carbon acetates or alcohol. Some of the selected chemicals selected from the electrophysiological experiments caused significant antagonistic or agonistic activities to the sex pheromone of each species in the field. In this study, the four species showed distinct chemical communication systems according to sub-family, which possibly serve as a factor in species isolation.

        Background: Propionibacterium acnes (P. acnes) is a major contributing factor for the inflammatory reaction of acne. Bee venom (BV) has been traditionally used to the treatment for inflammatory diseases. This study examined the anti-inflammatory effect of BV on P. acnes-induced inflammatory animal model. Methods: P. acnes were intradermally injected into both left and right ear of ICR mice. After injection, different concentrations of BV (1, 10 and 100 μg) mixed with 0.05 g of Vaseline was applied to the surface of the right ears of mice. Results: Histological observation revealed that P. acnes induced a considerable increase in the number of infiltrated inflammatory cells. However, BV treatment showed markedly reduced these reactions. Also, expression levels of TNF-α, and IL-1β were significant reduced in BV treated mice compared with P. acnes injected mice. The binding activity of NF-κB and AP-1 were increased in the P. acnes and Vaseline groups. In contrast, this enhancement of binding activity was markedly withdrawn after treatment with BV. Conclusion: In conclusion, this study indicates that BV has potential as an anti-acne agent and may be useful in the pharmaceutical and cosmetic industries.

        We have observed the emission of HC3N J=4-3, 5-4,10-9 and 12-11 transitions toward the Sgr B2 central region in an area of $150 with resolutions of 16'-48'. The intensities and central velocities of line profiles show significant variations with positions. In contrast to the intensities of the low J-level transitions which gradually increase from the central source toward the outside region, the HC3N emission of the high J-level transition become stronger toward 'the central radio continuum source MD5. Systematic change in the radial velocity of each line profile occurs along north-south direction. There are a few peaks in most line profiles, and these indicate that there are multiple velocity components along the line of sight. Distributions of excitation temperature and column density which were estimated from the excitation calculations show the existence of a small (1 X 2pc), hot (Tex>50K) core which contains two temperature peaks at-15' east and north of MD5. The column density of HC3N is (1-3)X1014cm-2 Column density at distant position from MD5 is larger than that in the central region. We have deduced that this 'hot-core' has a mass of 105M⊙, which is about an order of magnitude larger than those obtained by previous studies.

        Background : Pachyrhizus erosus (Leguminosae), locally called as “Yam bean” is a traditional medical plant that grows in the tropical and subtropical region. The root of P. erosus is used by the local people to treat insomania, treatment of osteoporosis and extracts of this plant have shown antioxidant activity, immunomodulatory activity, tyrosinase inhibitionby, antitumour properties and cardiovascular benefit. Methods and Results : Free radical scavenging activity was evaluated using α-tocopherol and butylated hydroxy toluene (BHT) as standard antioxidants. The radical scavenging activity was measured using the stable radical 1,1-diphenyl–2-picrylhydrazyl (DPPH) and ABTS assay. Total phenolic content was determined by following Folin-Ciocalteau colorimetric method and Total flavonoids were determined using aluminium chloride calorimetric methods. Phenolic compound concentration and compositions were determined by HPLC-MS/MS system. Seedlings grown under the flourescent light (Fl) exhibited the highest DPPH radical scavenging activity when compared to the plants treated with light emitting diodes (LEDs) and light emitting plasma (LEP). LED-Blue showed the higher DPPH radical scavenging activity and ABTS concentration of PE compared to other LEDs. The accumulation of phenolic compounds increased under different white-LEDs conditions as compared to LEP and FL light conditions. Conclusion : In this study, antioxidant activity and phenolic compound composition of P. erosus was improved by the application of LED and LEP.

        Background : Although ginseng has various bioactive compounds in it, there is lack of study on the variations of bioactive compounds in ginseng according to the cultivation soil and the applied fertilizer types (or amount). Therefore, this study aims to examine the variations of 37 fatty acids (FA) and 8 vitamin E (Vit-E) vitamers in 6-year-old ginseng root cultivated in different soil types with different fertilizers regimes. Methods and Results : The profiling of 37 FAs and 8 Vit-E vitamers in 6-year-old ginseng roots was measured by gas chromatography coupled with a flame ionization detector, and then these results were statistically analyzed with chemometrics. The FA and Vit-E content in ginseng roots varied significantly with respect to soil cultivation conditions due to organic fertilizer types and amounts used. Unsaturated FA in ginseng is approximately 2.7 fold higher than the saturated FA. Linoleic, palmitic, and oleic acids were the most abundant FAs found in the ginseng roots. Also, the major Vit-E vitamer found in ginseng root is α-tocopherol. In particular, the application of rice straw compost or food waste fertilizer was increased to create nutritionally desirable FAs and bioactive Vit-E in ginseng root. In addition, phytonutrient profiling coupled with chemometrics can be used to discriminate the cultivation conditions of ginseng. Conclusion : This study extends our understanding about the variations of FA and Vit-E in ginseng root depending on cultivation conditions. Hence, these results can be useful as basic information for reliable ginseng production containing high amounts of phytonutrients in a paddy-converted field.

        Background : The geographical origin of Panax ginseng Meyer, a valuable medicinal plant, is important to both ginseng producers and consumers in the context of economic profit and human health benefits. We therefore aimed to discriminate between the cultivation regions of ginseng using the stable isotope ratios of C, N, O, and S, which are abundant bio-elements in living organisms. Methods and Results : The C, N, O, and S stable isotope ratios were measured by isotope ratio mass spectrometer, and then these isotope ratios profiling was statistically analyzed with chemometrics. The various isotope ratios found in Panax ginseng roots were significantly influenced by region, cultivar, and the interactions between these two factors (P ≤ 0.0002). In particular, δ18O was lower in ginseng roots grown at high altitudes (r = −0.47), while δ34S was higher in ginseng roots grown close to coastal areas (r = −0.48). Chemometric results provided discrimination between the majorities of different cultivation regions. Conclusion : Our case study extends the understanding about the variation of C, N, O, and S stable isotope ratios in ginseng root depending on cultivation region. Hence, the analysis of stable isotope ratios is a suitable tool for discrimination between the regional origins of ginseng samples from Korea, with potential application to other countries.

        본 연구는 절임배추의 유통 중 단기 유통시스템에 따른 이화학적 및 미생물학적 품질 변화에 대하여 알아보고, 그에 따른 품질지표를 평가하고자 실시하였다. 여름철에 제조한 절임배추는 탈수 후 바로 저밀도 폴리에틸렌 필름에 포장하거나 2% 염수와 함께 포장하여 실온유통시스템(conventional system)과 저온유통시스템(cold-chain system)을 갖춘 1톤 트럭에 각각 구분하여 적재하였으며 약 6시간동안 유통하였다. 이화학적 및 미생물학적 변화로 품온, 염도, 산도, pH, 수분감, 일반세균, 젖산균, 대장균, 대장균군, 효모 및 곰팡이에 대해 조사하였다. 실온유통시스템의 경우 절임배추의 품온은 필름 내 염수포장 절임배추에서 19.57℃, 필름포장 절임배추에서 19.43℃, 저온유통시스템의 경우 필름 내 염수포장 절임배추에서 10.73℃, 필름포장 절임배추에서 12.90℃까지 증가하였다. 염도변화는 저온유통시스템의 경우 변화가 없었으나, 실온유통시스템의 경우 필름 내 염수포장 절임배추와 필름포장 절임배추에서 품온과 각각의 염도변화가 정의 상관성을 보이며 초기에 비해 1.2배 혹은 1.7배 더 높았다. 산도는 저온유통시스템에서 두 가지 포장조건 모두 약간 증가하였다. 실온유통시스템에서 필름 내 염수포장 절임배추의 총 호기성균과 젖산균수가 각각 7.62 log CFU/g 및 6.77 log CFU/g까지 증가하는 동안 필름포장 절임배추는 각각 5.62-5.85 log CFU/g과 4.33-4.83 log CFU/g의 범위를 나타냈다. 그러나 저온유통시스템의 경우 유통시간 증가에 따른 유의미한 미생물학적 변화를 보이지 않았다. 따라서 절임배추 유통 시 저온유통시스템을 이용한 경우 이화학적 품질 유지 및 미생물 제어에 효과적이며, 실온유통시스템을 이용한 경우 품온 상승에 따른 염도 및 미생물 변화에 유의해야 한다. 또한 염도, 총호기성균 및 젖산균은 실온유통시스템 내 품질지표로 이용가능하며, 산도는 저온유통시스템 내 품질지표로 이용가능하다.

        Background : Despite the presence of various bioactive compounds in ginseng, there is lack of study about the phenolic metabolites in ginseng especially depending on the cultivation soil and the fertilizer types. Therefore, this study aims to develop an (-)ESI-LC-MS/MS analytical method for the measurement of selected phenolic compounds in the ginseng root. Methods and Results : Total phenol content in ginseng root was measured with the Folin-Ciocalteau method using UV/Vis spectrophotometer. Then, the 56 selected phenolic metabolites in ginseng root were measured with the (-)ESI-LC-MS/MS. The brief LC-MS/MS analytical conditions were as follows; Thermo Scientific Syncronis C18 HPLC Column (250 × 4.6 mm, 5 μm) was used. Optimized instrument settings were as follows: Curtain gas 20 psi, collision gas 2 psi, ion spray voltage –4500 V, nebulizer gas 40 psi, heating gas 70 psi, and its temperature 350℃. Total phenol content was higher in the ginseng cultivated in the paddy-converted field than that in upland. In particular, the total phenol content was about 6% decreased in the ginseng root cultivated with the food waste fertilizer compared to the control (p < 0.05). Six phenolic constituents including caffeic, chlorogenic, p-coumaric, ferulic, gentisic, and salicylic acids were found in the ginseng root by using the LC-MS/MS in MRM (multiple reaction monitoring) Mode. These six phenolic compounds occupied approximately 20% of the total phenol content measured in the corresponding ginseng root. The chlorogenic acid was the most abundant phenolic metabolite found in the ginseng root, accounting for ≥ 95% of the sum of six phenolic compounds, in this study. Conclusion : This preliminary study can be useful for the study on content and composition of phenolic metabolites in ginseng root with the aspect of metabolomics. We plan to further optimize the LC-MS/MS analytical method and then provide the extended understanding on the phenolic metabolism in the ginseng root with respect to the ginseng cultivation conditions.
