This study is performed to verify the relationship between Korean's anniversary days and meals. To do so, three steps are carried out. First, literature review and mini focus group interview are performed to list up important anniversary days in our culture. Second, anniversary orientation scale(22 items) is developed. Third, a survey(n=486) is implemented to identify the relationship among demographic variables such as sex, age, and perceived economic level, psychological ariables such as self-esteem, life satisfaction, depression, individuality-relatedness, interpersonal sensitivity, materialism as a value and perceived social support, and meal frequency. The results are as follows: Female is significantly higher than male in anniversary orientation. And younger people(20~39 years old) are significantly higher than older people(over 40ties) in anniversary orientation. The higher life satisfaction, perceived social support, relatedness, interpersonal sensitivity, and materialism are, the higher anniversary orientation is. Lastly, middle and high anniversary orientation groups showed more meal frequency at the anniversary day than low anniversary orientation group.

Considering the increasing global burden of disease attributable to nutrition, the demand for national nutrition policies is growing stronger and stronger. The Republic of Korea is beginning to respond to this growing demand and there have been numerous recent achievements in the area of nutrition. The purpose of this paper is two fold. In the first part of the paper, an overview is provided about existing nutrition action in Korea. In the second part, information is elicited from Korean experts in the field of public health and nutrition. A structured questionnaire was sent directly to renowned Korean experts and was disseminated through the list serve of the Korean Nutrition Society. It asked about existing nutrition related policies, obstacles to nutrition policies in Korea, which professions are 'responsible' for the prevention of nutrition-related diseases and for example about existing nutrition programs within settings. Twenty-two questionnaires were returned. Based on the results, the following actions were considered crucial to develop and implement a nutrition policy in Korea: having a clear advocacy strategy for nutrition to raise awareness about the importance of nutrition, increase transparency of nutrition-related action and make the information easily accessible for all stakeholders, ensure the enforcement of regulations regarding misleading and incorrect food advertisements, strengthening the (public health) nutrition workforce, strengthen the settings-based approach and build and maintain partnerships, and last not least: educate and empower the citizens and ensure that healthy choices are 'easy choices'! Acknowledging the past and ongoing efforts in Korea, it is pivotal that the nutrition workforce grows stronger and the voice of nutritionists even louder, in order to promote and ensure the health and quality of life of the country's citizens.

Background: As the Positive List System (PLS) is implemented in broad application to agricultural products, attention to the correct use of pesticides is also needed in the production of mulberry leaves and fruit. In this regard, three types of pesticides against mulberry popcorn disease were applied 2 - 3 times both in the field and greenhouses to prepare safety standards. Residual pesticide analysis was conducted on mulberry fruits and leaves. Methods and results: Three pesticieds, thiophanate-methyl, thiophanate-methyl·triflumizole and fluopyram registered as PLS pesticides for mulberry popcorn disease, were sprayed in the Wanju and in Buan regions, after which residual pesticide analysis was conducted using high-performance liquid chromatography (HPLC). As three pesticieds were either undetected or below the permissible level in mulberry fruit, demonstrating that they were suitable for safe spraying. However, 5.6 mg/kg of thiophanate-methyl was detected in the greenhouse after three application, which was slightly above maximum residue limit (MRL). Furthermore the level of thiophanate-methyl·triflumizole was higher than 0.2 mg/kg ("Gwasang No. 2" variety, spraying twice) or similar to 0.09 mg/kg ("Daesim" variety, spraying thrice) the permissible level (0.1T mg/kg) as the thiophanate-methyl was detected in mulberry leaves in the greenhouse. Conclusions: The spraying frequency for controlling mulberry popcorn disease in greenhouses should be limited to two times or less, especially when mulberry leaves are treated with thiophanate-methyl·triflumizole careful consideration is required if the leaves are to be used as food materials.

Jukyeo (竹茹; Bambusae Caulis in Taeniam: BCT) is an herbal medicine made from the inner part of the bamboo stem of Phyllostachys nigra Munro var. henonis Stapf ex Rendle or Phyllostachys bambusoides Siebold et Zuccarini. Although medical literature published in China and Korea decades ago introduced BCT as a remedy for reducing vomiting, fever, and hematemesis, decoctions containing BCT as a main herb (君藥) in Korea have been approved only for treating neurologic symptoms. Here, we discuss the anti-inflammatory function of BCT. Combined with the clinical usage of a BCT-containing decoction in treating inflammatory diseases in Japan, we raise the possibility of repurposing the BCT-containing decoctions for treating inflammatory diseases. The anti-inflammatory activity of BCT was mainly assessed by using RAW 264.7 cells. The regulation of NF-κB, Nrf2 and A20 activities was determined by western blot and quantitative RT-PCR. The list of decoctions containing BCT currently approved in Korea was obtained from the Korean Ministry of Food and Drug Safety (KFDA). BCT suppressed the activity of pro-inflammatory factor NF-κB elicited by LPS, activated an anti-inflammatory factor Nrf2, and induced A20 that is known to block several inflammatory pathways simultaneously, suggesting that BCT can suppress inflammation via at least 3 different pathways. KFDA approved 11 decoctions containing BCT as a major herb, including Gamiondam-tang (加味溫膽湯; GOT), for treating neurologic disorders. Interestingly, Jukyeoondam-tang (竹茹溫膽湯; JOT), whose composition is almost identical to GOT except for one herb, has been used to treat inflammatory pulmonary disorders including Covid-19 pulmonary infection in Japan Given the anti-inflammatory function of BCT evidenced by medical literature and experimental results and the clinical usage of JOT in treating inflammatory pulmonary disorders, we suggest a repurposing and extension of the BCT-containing decoctions approved in Korea to treating inflammatory diseases.

Shark populations are constantly decreasing owing to environmental destruction and overfishing; thus, sharks are now at risk of extinction, with 30.5% of species classified as endangered on the International Union for Conservation of Nature's Red List. Sharks are apex predators and keystone species in balancing the marine food chain; their extinction would create an imbalance in the entire marine ecosystem. Assisted reproductive technology is a last resort for protecting animals facing extinction. Here, as a proactive effort toward building a hormone-induced artificial insemination protocol for endangered wild sharks, we identified the possibility of germ cell maturation by administration of GnRH, a commercially produced synthetic salmon gonadotropin-releasing hormone, and calculated its optimum dosage and injection timing. The experiment was conducted on one shark species, Chiloscyllium plagiosum. Injections were administered in 24 h intervals to C. plagiosum females, and 0.2 mL/kg+0.2 mL/kg were the optimal doses. These doses effectively induced maturation and, and ovulation, and oocyte release. Our results confirm that GnRH is a suitable tool for shark hormone-induced artificial insemination and indicate that this method may facilitate the conservation of endangered shark species.

This paper presents the first genome assemblies of Philippine mangoes that provide valuable reference for varietal improvement and genomic studies on mango and related fruit crops. WE sequenced whole genomes of3 species, Mangifera odorata (Huani), Mangifera altissima (Paho), and Mangifera indica 'Carabao' (Sweet Elena). 'Carabao' is the major export variety of the Philippines; Paho is identified as vulnerable by the IUCN Red List of Threatened Species; Huani has fruit sap acrid which is the primary defense mechanism against insects and birds. We used Falcon, a diploid aware -de novo assembler to assemble SMRT generated long-read sequences. Falcon-unzip was employed to phase the output assembly producing larger contig sets (primary contigs) and shorter contigs corresponding to haplotypes (haplotigs). Assembly statistics were generated by comparing the assembly to a reference genome, Tommy Atkins, using Quality Assessment Tool (QUAST). Moreover, the extent of duplication and completeness of gene content was measured using Benchmarking Universal Single-Copy Orthologs (BUSCO). Draft assemblies with high duplications were processed using Purge Haplotigs and Purge Dups to lessen duplications with minimal impact on genome completeness. De novo assemblies of Huani, Paho and 'Carabao' were then generated with primary contig sizes of 463.64 Mb, 508.95 Mb and 401.51 Mb respectively. These draft assemblies of Huani, Paho and 'Carabao' showed 96.90%, 95.17% and 99.07% complete BUSCOs respectively which is comparable to 'Tommy Atkins' genome (98.6%). Using two mango transcriptome data (pooled RNA-seq from different mango varieties and tissues), 91-96% or 24-30 million reads were successfully mapped back for each generated assembly indicating high degree of completeness. The results obtained demonstrated the highly contiguous, phased, and near complete genome assembly of three Philippine mango species for structural and functional annotation of gene units, especially those with economic importance.

In this paper, we propose a deep learning-based personalized senior care service application. The proposed application uses Speech to Text technology to convert the user's speech into text and uses it as input to Autogen, an interactive multi-agent large-scale language model developed by Microsoft, for user convenience. Autogen uses data from previous conversations between the senior and ChatBot to understand the other user's intent and respond to the response, and then uses a back-end agent to create a wish list, a shared calendar, and a greeting message with the other user's voice through a deep learning model for voice cloning. Additionally, the application can perform home IoT services with SKT's AI speaker (NUGU). The proposed application is expected to contribute to future AI-based senior care technology.

This study was conducted to investigate the dishes and menu patterns consumed frequently for 1 year, using estimated record method with 30 housewives. The purpose of this study was to suggest the dishes and menu pattern for the basis data of the nutrition education program and menu development project. The results were following : cooked rice and kimchi had the highest number of frequencies. The dish group (classified by the cooking method) consumed in largest quantities per capita per meal is the rice group (146.5g). Most frequently consumed dish group were the rice (72.7%), kimchi (60.6%), beverages (33.6%), fruits and juice (26.2%), soup (25.1%), stew and casserole (25.1%) in the order. Some dishes in several dish groups had small number of frequencies. Thus they were not included in the frequently consumed dishes list although they are in the top list of their own dish group. The menu had traditional menu pattern based on cooked rice, Korean soup, and kimchi. Most frequently used menu patterns were rice＋soup＋kimchi, rice＋noodle (or Mandu)＋kimchi, rice＋kimchi, rice＋soup＋kimchi＋seasoned-vegetable in the order. These were very simple menu patterns with only 1~2 kinds of side dish. Therefore, it is necessary for middle-aged housewives to consume menu that the composition of main dish and side dish are adequate. This result can be used as basic data for nutrition education programs in middle-aged housewives.

We assessed the pesticide residues in the medicinal agricultural products distributed in Korea. Pesticide residues in 72 samples were analyzed using the QuECheRS method for 339 pesticides, using GC-MS/MS and LC-MS/MS. The pesticide residues were below the maximum residues limit (MRL) in 42 samples (58.3%); however, they exceeded the MRL in 5 samples (6.9%). These included 43 types of pesticides; 20 fungicides and 23 insecticides were detected 75 times and 58 times, respectively. Tebuconazole and carbendazim were the most detected fungicides, each 11 times. The levels of acetamiprid, cadusafos, chlorpyrifos, flubendiamide, fluopyram, and triazophos exceeded the MRL in Gogi berry, Omija, and Reishi mushroom. All of them were positive list system (PLS) items that lacked pesticide residue standards. Therefore, authorities should monitor the distributed medicinal agricultural products.

Pesticide residues were monitored in dried red pepper and pepper powder samples purchased in Northern Gyeonggi-do and from domestic online markets. The QuEChERS method was used to prepare 88 samples. GC-MS/MS and LC-MS/MS were used to analyze 338 pesticide residues. In the study, pesticide residues were detected in 70 samples (79.5%), with residues exceeding the maximum residue limits (MRL) in 4 samples (4.5%). Pesticide levels exceeded the MRL in imported samples, with two samples of dried red pepper and two samples of pepper powder showing elevated levels. Among the 61 pesticides detected, tebuconazole, a fungicide was most frequently detected (52 times). Tricyclazole, which is used to control the main disease affecting rice, exceeding the MRL in 3 of 12 Vietnam-origin samples. Ethion exceeded the MRL in one Indian-origin sample. Both tricyclazole and ethion are banned for use in pepper products in Korea and are regulated under the positive list system (PLS). Conversely, pesticides detected in domestic samples were within the MRLs. Therefore, authorities should monitor pesticide residues in imported red pepper products.
