The study was conducted to investigate some grain quality characters related with brewing fittness for rice wine by adopting eight rice varieties as materials. Six japonica rice varieties except two Tongil-type rice had short and round grain of 1.80 or lower grain length/width ratio. 1000-grain weight of brown rice was 21.7~29.5g of significant difference among varieties. The white-center of rice grain was most severe in Hidahomare and Iri 402. Among tested varieties, Seomjinbyeo, Iri 402, Dongjinbyeo and Hidahomare had 50% or higher head rice ratio, while the others had relatively worse milling properties resulted from higher ratio of notched-belly and broken grain. Chemical components and total acid and amino acid content of refined rice wine was relatively good in every variety. Liquifying and saccharificating power was higher and koji conditon was also good in the varieties of high head rice ratio. Seomjinbyeo, Dongjinbyeo and Iri 402 was preferred in sensory test of refined wine and was recognized as superior adaptable rice varieties for brewing rice wine.

This experiment was conducted to determine the maximum dietary energy levels on growth performance and carcass characteristics of White Pekin duck. the Six dietary treatments were formulated based on their apparent metabolizable energy (AME) concentrations from 2,700 to 3,200 kcal/kg with a 100 kcal/kg gap to evaluate the accurate dietary AME requirement to address current knowledge and further issues for fulfilling the genetic potential of meat-type white Pekin ducklings. A total of 432 one-day-old male White Pekin ducklings were randomly allocated into one of six dietary treatments with six replicates (12 birds per pen). The diets were formulated as corn-soybean meal-based diets to meet or exceed the Nutrient Requirement of Poultry specification for meat-type ducks. Growth performance indices (i.e. average daily gain [ADG], average daily feed intake, feed conversion ratio) were measured weekly. Medium body weight (BW) ducklings from each pen were sacrificed to analyze the carcass traits and abdominal fat content on day 21. Obtained data were analyzed to estimate significant effect using the one-way ANOVA of IBM SPSS Statistics (Version, 25). If the p-value of the results were significant, differences in means among treatments were separated by Tukey's post hoc test. Significant differences were then analyzed with a linear and quadratic broken model to estimate the accurate concentration of AME. Ducklings fed higher dietary AME diets increased (p < 0.05) BW, ADG. Ducklings fed higher AME than 2,900 kcal/kg diets increased abdominal fat accumulation and leg meat portion. The estimated requirement by linear plateau method showed from 3,000.00 kcal/kg to 3,173.03 kcal/kg whereas the requirement by quadratic plateau method indicated from 3,100.00 kcal/kg to 3,306.26 kcal/kg. Collectively, estimated dietary requirements exhibit diverse results based on the measured traits and analysis methods. All the estimated requirements in this experiment present higher than previous research, the maximum requirement for the next diet formulation should be selected by the purpose of the diet.

The machine transplanted rice has highly extended in the Republic of Korea due to a wage rise since 1976 and thus rice seedling raising nursery method has shifted from field into polyethylene film house. The rice seedling grown under a polyethylene film house was weak and tall because of limited sunlight and wind and so there was so complained among rice growing farmers in terms of missing hill and broken seedling after machine transplanting. In recent iron-coated seedling has reported on healthier and stronger than that of polyethylene film house. These seedlings were more stiff and thus more easy to handle during transplanting and less missing hills. The Iron-coated seed was proven to more stiff like seedling height, root growth and weight of shoot and root growth. This was more convenient during transfer of seedling raising box im machine transplanting. Thus, this study was carried out to grow a stiff and healthy seedling growth and development for machine transplanting. There were a normal seed germination and sprouting after iron-coated seeds treatment and this seedling was smaller and stiffer than that of untreated control. The leaf number and root growth of seedling which was iron-coated seeds would be better and total seedling fresh weight was greater than that of untreated control.

The factors affecting the geotechnical properties of cemented sands are known to be relative density, cementation level, stress level, and particle characteristics such as particle size, shape and surface conditions. It has been widely accepted that the friction angle of cemented sands is not affected by cementation while the cohesion of cemented sands was significantly influenced by cementation. The cementation that is a critical component of the strength of cemented sands will be broken with increasing confining pressure and great caution is required in evaluating the cohesion of cemented specimens due to their fragilities. In this study, a series of drained shear tests were performed with specimens at various cementation levels and confining stresses to evaluate the strength parameters of cemented sands. From the experiments, it was concluded that the cohesion intercept of cemented sand experiences three distinctive zone(cementation control zone, transition zone, and stress control zone), as the cementation level and the confining stress varies. In addition, for accurate evaluation of the strength parameters, the level of confining stress triggering the breakage of cementation bond should be determined. In this study, the relationship between the maximum confining stresses capable of maintaining the cementation bond intact and unconfined compression strength of the cemented sand was established.

Current military command information system uses electronic equipment a lot on which semiconductor chip is attached. It seems its' importance will increase more with latest information communication technology developing. Electronic equipment which uses electricity contains regular tolerance to high output electric signal. And EMC specification is the standardized of this electronic equipment's tolerance. On the other hand, the Institute of Atomic Energy Research has ever declared that high output electromagnetic pulse(EMP) will be broken out within the radius of 170Km when 10kt nuclear explosion occurs at an altitude of 40Km above Seoul. Then, the region suffer from the damage of most electronic equipments. Therefore, the norm to protect the influences in that case is defined by EMP protection specification. Most common electronic equipments meet the EMC norm, but there is no way to check whether they meet the EMP norm or not. That is because it is difficult to check whether they meet EMP protection norm and is on the matter of cost. Except inevitable cases, there is no review of checking whether they meet the norm or not. Considering the above, in this research, we speculate about the measures to improve military EMP protection ability by analyzing the EMC-EMP correlation and checking the EMP protection ability of general electronic equipment through the analysis.

The hybrid phenomenon of pronunciation of K-Pop lyrics, which is the diction fusion phenomenon of lyrics, is not a strategic measure for an overseas expansion but a natural formation in the course of history of K-Pop. With the debut of Seo Tai-ji and Boys in 1992, the course of K-Pop changed and settled from ballad to dance music. After three years, the success of a hip hop dance music, 'Come Back Home', opened up a door to Korean Americans who ascertained the potential competitiveness of a hip hop music in K-Pop market. And the writer insists that such advance of Korean Americans into K-Pop market is the origin of the bilingual usage and diction fusion phenomenon of K-Pop lyrics. Therefore, this research will look into the pronunciation system of Korean and English in order to understand the bilingual pronunciation system shown in the lyrics sung by Korean American hip hop singers in the 1990s. Moreover, through Korean pronunciation system, this analysis will discover the main cause of continual acceptance and application of Korean American's broken Korean in the diction of lyrics. Last but not least, this exploration will show the correlation of English pronunciation method of Korean lyrics appeared in K-Pop and the diction of Korean lyrics used by Korean American hip hop singers in late 90s. This research will identify the primary cause of the diction fusion phenomenon in the course of history of K-Pop.

The movie Lolita is directed by the famous director Stanley Kubrick in the United Kingdom in 1962. Due to the movie theme, it produced a great social dispute at that year. Lolita was Stanley Kubrick's first independently produced film. It tells the story of the abnormal love between Professor Humbert from Europe and his stepdaughter Lolita. Throughout the film, it shocked people by feeling honourable and aesthetic although the theme is about commit incest. The director also completely shown the social reality of the United States in a black humor irony method. By the meantime, the lush tragic feature of the film also strongly infects the audience. Current studies on the movie Lolita mainly focus on the following aspects: firstly, the black humor techniques of director Kubrick's movies, secondly, the parody techniques of the movie, and thirdly, the differences between the original novel Lolita and the adapted movie. In the American society where consumerism constitutes the mainstream, instead of sticking to traditional moral concepts, people pursue material enjoyment. Based on the consumerism theory, this paper analyzes the social reality revealed by the movie Lolita, presents such typical characteristics of the consumerist society as hedonism and broken family relations, and explains how the consumerist society leads to Lolita's tragic life.

This article will analyze and forecast important variables and dynamics in global power politics after the war in Ukraine. It tries to use several perspectives to analyze international relations, particularly liberal internationalism and structural realism. In short, core variables are as follows; First, how is the US-led liberal international order and globalization being adjusted? Second, how will the U.S.-China strategic competition, which is the biggest and structural variable, cause changes in the international order in the future? The third variable, how stable are Sino-Russia relations in the context of a structuring U.S.-China-Russia strategic new triangle? Fourth, to what extent will third middle hedging states outside the U.S. and China be able to exercise strategic autonomy in the face of multipolarization? To summarize, the first of these four variables is the largest basic variable at the global political and economic level in terms of its impact on the international community, and it has been led by the United States. The second variable, in terms of actors, seems to be the most influential structural variable in global competition, and the US-China strategic competition is likely to be a long game. Thus the world will not be able to escape the influence of the competition between the two global powers. For South Korea, this second variable is probably the biggest external variable and dilemma. The third variable, the stability of Sino-Russia relations, determines balance of global power in the 21st century. The U.S.-China-Russia strategic new triangle, as seen in the current war in Ukraine, will operate as the greatest power variable in not only global power competition but also changes in the international order. Just as the U.S. is eager for a Sino-Russia fragmentation strategy, such as a Tito-style wedge policy to manage balance of power in the early years of the Cold War, it needs a reverse Kissinger strategy to reset the U.S.-Russia relationship, in order to push for a Sino-Russia splitting in the 21st century. But with the war in Ukraine, it seems that this fragmentation strategy has already been broken. In the context of Northeast Asia, whether or not the stability of Sino-Russia relations depends not only on the United States, but also on the Korean Peninsula. Finally, the fourth variable is a dependent variable that emerged as a result of the interaction of the above three variables, but simultaneously it remains to be seen that this variable is likely to act as the most dynamic and independent variable that can promote multilateralism, multipolarization, and pan-regionalism of the global international community in the future. Taking into account these four variables together, we can make an outlook on the change in the international order.

This study conducted an empirical analysis of the factors affecting the job commitment of employees within a financial sales organization, focusing particularly on agile leadership and organizational justice. Agile leadership was subdivided into four components: adaptability, collaboration promotion, proficiency, and an agile approach, whereas organizational justice was broken down into distributive justice, procedural justice, and interactional justice. Data were gathered through an online survey, and 245 valid responses were subjected to hierarchical regression analysis. The results revealed a significant positive effect of distributive justice, interactional justice, adaptability, promotion of collaboration, and an agile approach on job commitment among the employees of the financial sales organization. However, the influence of proficiency, a component of agile leadership, and procedural justice, a dimension of organizational justice, did not prove to be statistically significant. The order of influence among the significant variables was found to be: adaptability, interactional justice, promotion of collaboration, distributive justice, and an agile approach. These findings confirmed the impact of agile leadership in financial sales organizations, traditionally viewed as conservative, and suggested practical implications for the financial sector to adapt in anticipation of the Fourth Industrial Revolution.
