Changes of rice yield and soil physicochemical properties of the dry-seeded rice-barley double cropping system were investigated for 10 years from 1990 to 1999. Generally, seedling stand was more unstable in the rice-barley cropping system regardless of barley straw addition or removal than in the rice single cultivation as indicated by higher standard deviation of seedling stand across year. Rice yield in rice-barley double cropping cultivation was increased due to barley straw application starting from the second year, recording 2 to 19％ increase (average of 9％ for 10 years) due to higher spikelet number. Protein content and Mg/K equivalent ratio were similiar among the barley straw applied field, rice single crop and barley straw removed plots. Also, amylose content was not significantly different among cropping patterns. Physicochemical properties of soil was improved by applying the barley straw; soil porosity was higher and content of organic matter and cation exchange capacity of Ca increased but those of Mg and K did not differ.

The influence of cool temperature occurred during the booting stage in 1993 on quality of rice grain was compared with that in favorable weather of 1994. The mean and minimum air temperatures during the reproductive growth stage at the paddy field of Jinbu Substation, National Crop Experiment Station were 2.2~7.4$^{\circ}C$ and 2.0~8.9$^{\circ}C$ lower respectively in 1993 compared to those of 1994. Grain fertility and brown rice yield were 11.8％ and 0.4t /ha, and 84.3％ and 5.5t /ha in 1993 and 1994, respectively. There was no difference in amylose content between two years. However, protein content of brown rice in 1994 were 1.6％ lower than that of 1993. There was no difference in alkali digestion value of milled rice between two years. Gel consistency of rice flour was 45mm in 1993 and 59mm in 1994. Amylogram characteristics of rice flour produced in 1993 showed lower peak hot, cool, and breakdown viscosities, and higher consistency and setback viscosities. The palatability of cooked rice by sensory panel test was considerably better in 1994 rice than in the rice of cool year.

The leaf color varies with the contents of pigments, especially chlorophylls and carotenoids. Teichung 65 (T.65), a japonica rice, with pgl(pale-green leaf) gene exhibits pale green color on the whole plant from seedling to harvest. This study conducted to evaluate the agronomic characters and examine the chloroplasts of 'pgl' plants in parents and BC$_1$F$_2$ of T.65(pgl) xSuweon ${345}^2$. The average grain yield of pale-green-leaf individuals in F$_2$ was the same as T.65(pgl) but that of green-leaf individuals was much higher than that of Suweon 345. The contents of chlorophyll a(Ca), chlorophyll b(Cb) and total chlorophyll content(Ct) of T.65(pgl) in flag leaf were lower than those of Suweon 345, but the Ca/Cb ratio of T.65(pgl) was higher than that of Suweon 345 during from 15 days after heading (DAH) to 60 DAH. The SPAD value of T.65(pgl) in flag leaf was lower than that of Suweon 345, but that in the second and the third leaves was similar to that of Suweon 345. The SPAD value of pale-green-leaf individual group was lower than that of green individual group in upper three leaves. The structural difference of chloroplasts in flag leaf between T.65(pgl) and Suweon 345 through TEM at 20 DAH was not detected, but the number of osmium granules in chloroplast of T.65(pgl) were higher than that of Suweon 345.

Purpose There are reports that the COVID-19 vaccine causes false positive uptake of axillary lymph nodes. Therefore, this paper intends to evaluate the change in SUVmax of axillary lymph nodes with the period after the COVID-19 vaccination. Materials and Methods In 134 breast cancer patients who were tested for ¹⁸F-FDG PET/CT at Severance hospital, 3.7 MBq/kg of ¹⁸F-FDG was intravenously injected and scanned for 2 minutes per bed after 60 minutes. The equipment was Discovery 600 (GE Healthcare, MI, USA). The period was divided into four groups, 0 to 2 weeks, 3 to 6 weeks, 7 to 10 weeks, and 11 weeks or more. SUVmax was measured after checking the uptake of axillary lymph nodes on the ipsilateral side of vaccination and the Kruskal-Wallis test was performed using SPSS Statistics 28 (IBM Corp., Armonk, NY, USA). Results From 0 to 2 weeks groups to 11 weeks or more group, the average of SUVmax was measured in the order of 5.52, 2.85, 1.82, and 1.7. As a result of the Kruskal-Wallis test, there was a significant difference between 0 to 2 weeks group from all other groups (P < 0.05), and there was no significant difference between the remaining three groups. Conclusion The SUVmax of axillary lymph nodes decreased over the period after the COVID-19 vaccination and no significant difference was found after 3 weeks of vaccination. Therefore, it is recommended to record COVID-19 vaccination information before examination.

So far there has been a strong tendency to study The Great Learning in terms of quite" limited ethical and moral understandings." Yet The Great Learning was originally a political text to educate the ruler. So the ethical and moral understanding discussed in the book should be interpreted as something more comprehensive and practical, which includes the political ability. This paper thus focuses on this new line of understanding of The Great Learning. Among the three principles of the book, 'Myeongmyeongdeok( 明明德)' means the virtue of a politician, that is to 'cultivate (Myeong)' the 'properties for a statesman (Myeongdeok).' 'Sinmin (新民)' means 'to innovate or reform the people as a result of substantive administration of a politician'. 'Jieojiseon (止於至善)' means 'to reach and to maintain the highest degree of goodness as a result of Myeongmyeongdeok and Sinmin'. These three principles would divide into eight practicums. Myeongmyeongdeok would divide into five steps of 'Sugi(修己: Cultivating the self)' practicum, which are 'Gyeokmul (格物) → Chiji(致知) → Seongeui(誠意)→ Jeongsim (正心)→ Susin (修身)'. Sinmin would divide into three steps of 'Chiin (治人: rule the people)' practicum which are 'Jega(齊家) → Chiguk(治國) → Pyeongcheonha(平天下).' And the point where the two practicums are harmonized, i.e. that of Sugichiin (修己治人), is the place of Jieojiseon. Not every ethical people become a politician but every politician must be ethical. That is the assertion of the Great Learning.

I insisted that the structure should be set newly, pointing out problems in a structure of the big gut, Jain dano je in this paper. Although, the big gut is playing now in Jain dano je, the features of gut geo-ri are vague ; that's why gut geo-ri and performances are entangled. Therefore, the gut geori showing strange structures not fitted with korean shamanist custom is playing these days like Pawangbyeolhui and Eoudong geori. The detailed procedure is also awkward. It is mixed with aspects of shaman custom in each region, instead showing features of regions. What's more, it became a dance drama, not gut geo-ri with several shamans dancing in a gut. Overcoming these problems, the big gut will be a cultural asset. Therefore, when considering the structure of korean gut, we will fit the order of gut geo-ri into the system of divine spirits keeping a plot-opening, developing and closing. It should be a gut geori-oriented play with only gut geo-ri things. Gut should be gone forward main shaman-oriented gut, setting up a main shaman who takes charge of each gut geo-ri. We should find out a new shaman who knows gut of Gyeong sang province well, if shaman who now takes charge of it has a problem. The big gut of Jain dano je became a part of intangible cultural assets. The performance is not a subject of curiosity and people's interests any more as it was in a past. It should be a traditional performance of representing our traditional culture. We should reorganize an epochal gut geo-ri after reexamining gut geo-ri which has played so far.

In the age of digital media transformation, the rapid rise of social media has changed the paradigm of traditional marketing techniques by leveraging the influence of influencers. However, the influence of influencers cannot be freed from ethical issues that arise as individuals, so virtual influencers are emerging as a countermeasure. This study is a study on how to increase the influencer effect of virtual models with a focus on the MZ generation in medical service. This study investigated whether respondents in their 40s or younger were aware of 'Rosy', a virtual influencer, and then conducted a survey on those who recognized 'Rosy'. As a result of this study, first, both cognitive and emotional motivation had a positive influence on fanship and attractiveness for virtual influencer. In addition, it was found that there was a difference in follow motive according to gender. Second, in order to lead to the intention of visiting hospitals, which is the medical service industry, only the cognitive motives with useful and reliable information and useful information for the virtual influencer were found to be significant in intention to visit.

This paper is focusing on the optimal size of internal space in which various functions are expressed by means of analogizing appropriate size of passage fitted to characters and reverse-calculating it in comparison with preexisting games, and thus increase the objectivity of data. To this end, the work of making the data objective was conducted in advance, and the experiment proceeded in the way that specially-designed Dungeon can make its way through the passage and in the situation where small-scale combats take place. In addition, the efforts were made to standardize the outcome of experiments by restricting the types of game graphics to MMO RPG. Further, the enhance the objectivity of size of the characters, the game types were limited to RPG games, and it is also adjusted to the character's face size based on the graphic designer's preference. The size of shoulders and arms of characters, inter alia, was selected as distinguishing points to be adjusted to the passage. By analyzing these data, the size of passage was re-organized according to the main characters in the MMO RPG games. Four experimental data was utilized by the 200 game experts in order to select the optimal size of passage in the game. As a consequence, the proportional correlation between character and passage movement was evaluated as successful in terms of emotional recognition.
