There is a need to breed and distribute domestic varieties for Lilium Asiatic hybrids because most of the lily bulbs cultivated in Korea imported from foreign country. The genetic resources of Lilium Asiatic hybrids, 'Buff Pixie', 'Orange Matrix' and 'Tiny Puppet', which were collected from 2001, had been self-pollinated from 2004 to 2012. In 2012, Lilium Asiatic 'Lovely LiASong' as an F₁ hybrid was bred through crossing 'L₂-12-1' and 'L₂-35-4' obtained by 4th self-fertilization. 'Lovely LiASong' had a bowl shaped single flower with a few spots and medium-sized flower, 8.7cm in flower diameter. The number of flowers per plant was 4.9, which was relatively more flowers than other cultivars. And the flower inflorescence had umbellate and racemose while the attitude of longitudinal axis was erect. The plant height was 33.4cm with 30.4 leaves per plant and 7.2cm in leaf length. The 'Lovely LiASong' showed a high consumer preference because it had a relatively longer flowering period, larger flower diameter and number of flowers than those of the control, 'Tiny Ghost'.

This study aims to implement a Regression Analysis system for predicting the appropriate production of flatfish. Due to Korea's signing of FTAs with countries around the world and accelerating market opening, Korean flatfish farming businesses are experiencing many difficulties due to the specificity and uncertainty of the environment. In addition, there is a need for a solution to problems such as sluggish consumption and price drop due to the recent surge in imported seafood such as salmon and yellowtail and changes in people's dietary habits. in this study, Using the python module, xlwings, it was used to obtain for the production amount of flatfish and to predict the amount of flatfish to be produced later. was used to predict the amount of flatfish to be produced in the future. Therefore, based on the analysis results of this prediction of flatfish production, the flatfish aquaculture industry will be able to come up with a plan to achieve an appropriate production volume and control supply and demand, which will reduce unnecessary economic loss and promote new value creation based on data. In addition, through the data approach attempted in this study, various analysis techniques such as artificial neural networks and multiple regression analysis can be used in future research in various fields, which will become the foundation of basic data that can effectively analyze and utilize big data in various industries.

Rehmannia glutinosa is a perennial herb belonging to the family Scrophulariaceae and is used in traditional oriental medicine. This study was carried out current status of breeding of R. glutinosa, its problems, and the matters to be improved were made. Based on the research data published so far, this study summarized the characteristics of breeds cultivated in Korea and compared and analyzed the status of cultivation area, production, import, and price changes for 15 years from 2008 to 2021. The cultivated area of R. glutinosa is gradually decreasing, and the amount of import is increasing and decreasing repeatedly. Amount of import has declined significantly. There was a lot of disinfection and disposal in the middle of import, and dried Jihwang and Sukjihwang were imported without distinction. R. glutinosa must be cultivated and supplied as a variety desired by the industry, cultivation techniques need to be taught to producers. In order to clearly identify the amount of import, import code of dried Jihwang and Sukjihwang must be classify. In addition, it is necessary to develop and supply harvesting agricultural machines for mechanization. For the stable income of producers, supply control through contract cultivation will ensure stable farm income.

Background: The aim of the present study was to determine radioactive concentrations in fertilizers known to contain essential nutrients. Results of this study could be used as basic data to monitor the impact of chemical fertilizers on the environment and public health. Nitrogen fertilizers, calcium fertilizers, sulfur fertilizers, phosphate acid fertilizers, and potassium chloride fertilizers were used in this study. Materials and Methods: Five chemical fertilizers were pulverized, placed in polyethylene containers, and weighed. The time to measure each specimen was set to be 3,600 seconds for a scintillator-based gamma-ray spectroscopy system. Concentration of gamma radionuclide was analyzed based on obtained spectra. At the end of the measurement, the spectrum file was stored and used to calculate radioactive concentrations using a gamma-ray spectrometer software. Results and Discussion: In the nitrogen fertilizer, 3.49 ± 5.71 Bq/kg of ¹³⁷Cs, 34.43 ± 7.61 Bq/kg of ¹³⁴Cs, and 569.16 ± 91.15 of ⁴⁰K were detected whereas ¹³¹I was not detected. In the calcium fertilizer, 5.74 ± 4.40 Bq/kg of ¹³⁷Cs (the highest concentration among all fertilizers), 22.37 ± 5.39 Bq/kg of ¹³⁴Cs, and 433.67 ± 64.24 Bq/kg of ⁴⁰K were detected whereas ¹³¹I was not detected. In the sulfur fertilizer, 347.31 ± 55.73 Bq/kg of ⁴⁰K, 19.42 ± 4.53 Bq/kg of ¹³⁴Cs, 2.21 ± 3.49 of ¹³⁷Cs, and 0.04 ± 0.22 Bq/Kg of ¹³¹I were detected. In the phosphoric acid fertilizer, 70,007.34 ± 844.18 Bq/kg of ⁴⁰K (the highest concentration among all fertilizers) and 46.07 ± 70.40 Bq/kg of ¹³⁴Cs were detected whereas neither ¹³⁷Cs nor ¹³¹I was detected. In the potassium chloride fertilizer, 12,827.92 ± 1542.19 Bq/kg of ⁴⁰K was and 94.76 ± 128.79 Bq/kg of ¹³⁴Cs were detected whereas neither ¹³⁷Cs nor ¹³¹I was detected. The present study examined inorganic fertilizers produced by a single manufacturer. There might be different results according to the country and area from which fertilizers are imported. Further studies about inorganic fertilizers in more detail are needed to create measures to reduce ⁴⁰K. Conclusion: Measures are needed to reduce radiation exposure to ⁴⁰K contained in fertilizers including phosphoric acid and potassium chloride fertilizers.

In this paper, I want to compare the mantra of Korean Buddhism with the jumun(呪文) of Daesoonjinrihoe in rites and cultivation. Regarding the mantra of Buddhism there are some researches, but there are few studies with regard to the jumun of Daesoonjinrihoe. The mantra of Buddhism and jumun of Daesoonjinrihoe look similar in pronouncing Hangul characters, but the religious and historical context around these seems to be different. The mantra of Korean Buddhism is associated with the introduction and diffusion process of esoteric Buddhism. In the early period of Buddhism some mantras were allowed by Buddha and the mantras were certified as a educational teaching in the period of Early Buddhist schools. In Mahayana school, the dharani that was abstracted from the vast Mahayana scriptures was developed. As Mahayana Buddhism develops, esoteric Buddhism was born in India. Esoteric Buddhism was introduced into China and was imported into Korea in Silla dynasty. In Koryo dynasty various rituals of esoteric Buddhism flourished and Jineunjong(眞言宗) and Chongjijong(總持宗) school were formed. In Chosun dynasty Buddhism was suppressed by government and the esoteric school was discontinued. But in rituals and cultivation the mantra and dharani were flourished in the latter part of Chosun dynasty. In modern period several esoteric schools were formed and developed. In present context the mantra was recited by many people in Korea. Main mantras are 'Om mani padme hum', 'Dharani of Avalokitesvara(神妙章句大陀羅尼)', 'neungumju(楞嚴呪)', 'Gwangmyung mantra(光明眞言) etc. The jumun of Daesoonjinrihoe was started by Kang Jeungsan(姜甑山) who was believed to be a God by Daesoonjinrihoe believers. Jeungsan used several existed mantras in creating new heaven and earth and made new jumuns by himself and taught them to his followers. Cho Jungsan(趙鼎山) who succeeded to the doctrines has received the jumuns by Jeungsan. He selected the jumuns to recite and determined the method how to spell these. Park Hankyung(朴漢慶) who opened Daesoonjinrihoe succeeded the rituals and doctrines. Every day ritual of Daesoonjinrihoe is chanting the jumun and the cultivation and gongbu(工夫) is practiced through jumun. Important jumuns of Daesoonjinrihoe are Taeulju(太乙呪) and Kidoju(祈禱呪). In the aspects of ritual, the mantra of Buddhism and the jumun of Daesoonjinrihoe perform a similar function. The mantra of Buddhism has the context of the doctrines of Buddhism and the method of Buddhistic practicing but the jumun of Daesoonjinrihoe is related to Jeungsan's teaching and the doctrines of Daesoonjinrihoe. But it is same that the mantra and jumun are used in communicating or uniting with ultimate reality. So the mantra and jumun are important vehicles for homo religius to meet the sacred and unite with the sacred and is regarded as the sacred word by the faithful which has a lot of symbols and meanings.

In case of Aju capital, it adopted a strategy to use a single brand not two separate brands after M&A was completed. In order to implement this strategy, it has endeavored to effectively process the work of shifting existing marketing infrastructure of DAEWOO capital, the mergee, spending enough transition time for the brand migration. In the process of merging, Aju capital picked the strategy to use the brand of mergee first, which is the Daewoo Capital brand, and then took a transition time for a while to converge to the single brand of Aju capital. Putting another way, even if the M&A deal was completed back in 2005, it maximized the effect of launching its final brand "Aju capital" by capitalizing on the positive image of "Daewoo" during the transition time and changing its name just in the right moment. In a bid to implement this strategy successfully, it established a cautious but sophisticated brand migration strategy. 1) "Brand bridge" strategy through reinforcing brand power of "Naegeron", which is an individual product brand of Daewoo Capital 2) Establishing a good brand image through reinforcing customer satisfaction 3) It implemented and completed its brand transition initiative by going through the step of Aju Capital brand unification (from Sept 09 to present) Currently, the sales unit of Aju Capital is realizing quality growth through specialization. It's strategy is to construct a systematic sales portfolio in terms of both quality and quantity through product-by-product specialization where the existing practice was selling a variety of products in a single branch. Back in 2009, it opened a branch that specialize in imported cars and expanded its used car business to 6 specialized locations. Besides, the specialized locations for personal loan named "Naegeron" was expanded from 3 to 11 locations. Recently, it is expected that it will inject vigor to retail and corporate financing business alongside with its core business, which is auto financing.

Wheat was brought to solve food scarcity with aid from the United States caused by the Korean War. The Korean government launched a campaign to encourage mixed rice and wheat meals due to shortage of rice production in the 1960s, Wheat consumption began in earnest. However, it is difficult to rebuild the domestic wheat production base devastated by the Korean War with the technology at the time. Thus, wheat was mainly consumed from imported in the past. Since then, as wheat consumption has increased due to westernization and diversification of dietary life, wheat became the second staple grain in Korea. In this situation, the government enacted the Wheat Industry Promotion Act to create a basis for sustainable production and consumption of wheat in Korea. This study sought to improve the self-sufficiency of domestic wheat by examining the possibility of using "Ariheuk", a variety of new Korean wheat, as a rice supplement in the same context as the govemment's policy. Wheat has been used as a raw material for the processed food, such as noodles and bread. However, we approached it by using whole wheat as a nutritional grain. Participants were recruited from the agri-food consumer panel conducted by Rural Development Administration. We set a final sample of 525 consumer panels based on the age of census household heads. The experiment was conducted in such a way that participants cooked and ate 100% rice meal and rice containing 20% whole wheat meal. Participants completed the sensory evaluation questionnaire with online. For this experiment, all participants were given same whole wheat product. The sensory evaluation questionnaire consisted of color, glossiness, stickiness, aroma, chewing, sweetness, nuttiness, chewiness, softness, bursting, flavor, texture and swallowability. The sensory evaluation results were analyzed by giving -3 points to +3 points. The former points were given to the response that 100% rice meal is very superior to the response that rice containing 20% whole wheat meal. The latter points were given vice versa. Zero point was given to the response that they are similar each other. As a result, rice with 20% whole wheat meal was better than 100% rice meal in terms of color, aroma, chewiness, bursting and flavor. In case of sweetness and glossiness, there didn't exist significantly different. On the other hands, 100% rice meal was better in terms of softness and swallowability. As a result of ANOVA by age groups, from 30s or younger to 60s or more, there was significant difference among the groups in terms of color, chewiness and bursting. As a result of post-hoc analysis with Duncan's multiple range test (p < 0.05), 50s were evaluated to be significantly superior in color, chewiness and bursting compared to other age groups. In conclusion, it is appropriate to use whole wheat as a supplement to rice in order to improve the self-sufficiency of domestic wheat. As a strategy to promote domestic wheat consumption, in case of Ariheuk, it is necessary to provide an experience through whole wheat tasting and to establish a marketing strategy segmented by age groups.

Prolonged Russia-Ukraine war, and unstable situation of supply and demand of global crops including the COVID-19 pandemic have raised awareness regarding food crisis, and in addition to this situation, export restriction measures imposed by some countries have accelerated the rise in the prices. Since the Republic of Korea depends annual crop consumption (21.32 million tons) mostly on the imports (food self-sufficiency rate in 2020 was 45.8%, crop self-sufficiency rate was 20.2%), our main task is to stably secure food. Now we need to put focus on building capacity to secure stable food supply, and actively manage and respond to risks. To overcome this condition, the Korean government set robust food sovereignty as its policy task, and has been focusing on the policy capacity by providing financial and policy support in parallel. We need to implement mid- to long-term measures to strengthen food security as well as to ensure domestic price stability. While increasing the domestic capacity to supply food in the mid- to long-term perspective, we are implementing projects to bring in crops which are inevitable to be imported by private companies. Specifically, we are making efforts to expand infrastructure for the public reserve and domestic production of wheat and beans which have low self-sufficiency rate, and to secure food sovereignty by providing support to secure global crop supply chain to private companies. The Ministry of Agriculture, Food and Rural Affairs plans to set a target for food self-sufficiency rate and prepare a policy to strengthen mid- to long-term food security by establishing a task force to strengthen mid- to long-term food security in the Ministry. Especially, although wheat is the second staple food, domestic wheat production and the foundation for the industry is poor. Compared to the wheat imports, domestic production of wheat is 30 thousand tons (self-sufficiency rate of 1%), leading to a vulnerable status against internal and external shocks. Through the establishment of the Wheat Industry Promotion Act (Feb. 2020) and the First Master Plan for Wheat Industry Promotion (Nov. 2020), the Korean government has developed a policy basis, and has been providing financial support in overall across the production, distribution and consumption process. In addition, the government established a production complex for Korean wheat and beans in order to supply affordable government-supplied commodities, provide education and consulting services, and create a high-quality stable production system, including facilities and equipment. We are also continuing to increase the public reserve for wheat and beans with the purpose of stable supply and demand as well as food security. The Korean government will establish and implement mid- to long-term measures to strengthen the foundation for domestic production across production, distribution and consumption process, and to stably secure global supply chain including through diversified import channels.
