With the arrival of the 21th century, the management environments such as the knowledge system, information system, and technology system surrounding small and medium enterprises are being rapidly changed. These rapidly changing the environment of enterprises like the above can be thought rather profitable for the elastic and resiling medium enterprises than large enterprises. Additionally, these environments are recognized as the management circumstances which provide with the change by which medium enterprises equipped with the trustworthy creativity in the 21th century are able to become the main player of the industrial development. The position and role of medium enterprises in the national economical system are very important. The execution of the local autonomy system and the policy to activate the local economy will generally enlarge the power of medium enterprises which are based on the concerned local society more ant more. But, by the standpoint of designer, it is pointed out that there is the problem that the effective application means or the availability of the industrial design was not sufficiently recognized or understood by the manager in enterprises. Notwithstanding the above problem, a lot of domestic small and medium enterprises became to apply the industrial design as the means for improving the competitiveness of their own products in the relatively short time powered by the governmental policy, and moreover both of the concerned partners(the manager and industrial designer) had the opportunity to newly recognize the industrial design and evaluate the availability or problem of the industrial design in the actual aspect. This event means very important change. With the understanding on the above situation, the purpose of this study is to recognize whether the design is strategically applied in the management level of domestic small and medium enterprises, whether the strategical establishment of the design management is performed without any problem, whether the field designer and CEO are well recognizing the design management and what their recognition level is in order to seek the new solution for plenty of problems. Therefore, the actual proof analysis was performed for the field designer and management CEO of small and medium enterprises with the questionnaire survey and direct interview method to understand the actuality of small and medium enterprises.

Though human being has ability to percept a full colored vision, the technology of early photography only can produce black and white images. For cinema filming imagery also captured mono tone with black and white, until developed a color film technology. The desire for presenting color imagery and the technique for producing film and color ink, photography and print utilize color on it with noticeable color impact to viewers. It, however, abusing fun colors image each and every printed and filmed imagery, the freshness of eye catching power diminished now. On contrast, color becomes black and white or partially used for making discrepancy among full colored images. This image detected commercial and music video, and it spread to film. To use those bleached color images is for evoking a nostalgia and a visual differentiation. Especially, it can be provocative images brought to audience with that. such as "Anycall", "Dimchae" for CF, and "Schindler's list," and "Sin city" for movie. It is hard to investigate on the color studies for partially used images. Therefore, this study is to research that through CF and film, base on it, to investigate the application for this image. To collect data from survey, it will be established a basic concept for understanding the partial color applying.

Although more than 80% of living organisms are found in marine ecosystems, only less than 10% of marine resources have been utilized for human food consumptions and other usages. It is well known that marine resources (fish, shellfish and algae) have exceptional nutritional properties; however, their functional characteristic has not been completely discovered. It is believed that metabolites (organic compounds, proteins, peptides, lipids, minerals, etc.) play an important role to show its biological properties. Marine proteins and peptides are considered to be future drugs due to their excellent biological activities with a fewer adverse side effect. Marine peptides show several biological activities, including antimicrobial, antioxidant, anti-inflammatory, anti-cancer, anti-viral, anti-tumor, anti-diabetic, anti-hypertensive, anti-coagulant, immunomodulatory, appetite suppressing and neuroprotective effects. Therefore, the pharmaceutical, nutraceutical, and cosmeceutical companies have been paid attention to the marine peptides to commercialize into products. This current review mainly focused on the above mentioned biological activities of marine peptides and protein hydrolysates as a functional food and pharmaceutical applications. To commercialize these materials in industrial level required large quantity in high-purity level, and it is complicated to produce huge quantity from the marine resources due to insufficient raw materials, unavailability of raw materials through a year, hinder the growth with geographical variations, and availability of compounds in extreme small quantities. The best solution for these issues is to introduce new modern technologies such as artificial intelligence robots, drones, submersibles and automated raw material harvesting vessels in farming industries instead of man power, which will lead to 4th industrial revolution.

The volume of world market for serious game in year 2015 is expected to be about 9.6 trillion, and the volume of educational serious game market is expected to surpass half of the whole serious game market. In Korea, the development of game for educational purpose has dominated around the education enterprises since late 90s. In 2008, 'Serious Game Forum' was founded led by the Ministry of Culture, Sports, and Tourism with experts from many fields in the society and there were progressing of making policies and plans for potential development of the serious game industry, but the effects were not successful than expected. In 2012, the Ministry of Education, Science, and Technology announced commercialization policy of digital textbook by 2015 and the serious game for educational purpose got attention again. Then, the serious game market became more vigorous with the dispersion of smart devices.13) As a result, the serious games on the smart devices or interlocking between the online and smart devices became an important issue in development rather than the online only serious games. Math field has international competitive power through export in the educational serious game market which takes more than half of the serious game market. Therefore, developing serious game for math education is a good area to raise competitiveness in domestic and international game industries. Moreover, it has no received preferences from students and parents although it has high potential for positive change of individuals and society. The reason is that students recognize it as educational content rather than a game and they avoid it, while parents recognize it as game but not an education. This phenomenon happens because the game elements and educational elements are not properly mixed but focused only on education or emphasized only the fun factors of game when it was developed. Therefore, the purpose of this research is to suggest a direction of developing serious games effectively combining with elementary math for elementary students to get interested in math while playing games. The research will analyze the current elementary math textbooks and find contents which may be combined with the game genre that elementary students enjoy playing these days. This research received advice from serious game developers and math education expert group to reflect the inclination of elementary school students, and respond to the demands from parents and educational institutions, and suggested a direction of developing serious games for effective math education.

While the lecture activities in Simwonsa, Ganjae Jeon Wu(1841~1922) has established a "law of lecture activities" which was an ritual between a teacher and pupil, between the couple. Through this way he expected to recover the former ritual, even within their own school. In 1884 he built a "law of Sidong school", meaning to build a large object, elementary scholarship will serve as the rules of conduct, and argued that human nature mainly served to the core in the course of study. Ganjae in Mungyeong area was also discussing studies with Song Byeong-hwa(1852~1916) and received correspondence with scholars in areas related to Mungyeong. They were Kim Jae-kyung(1841~1926) and Park Se-hwa (1834~1910). Ganjae had also some big national events on the sojourn time in Mungyeong. In 1882 there were army incident, in 1884 there were a command of the government that people must pull on western clothes. Ganjae did not follow the command of the government. Someone asked "Can we not follow the command of the government?" Ganjae replied "We have a right to resist to the illegal command of the government. There were also 1884's Gapsin-coup, Ganjae saw that we must defend the country by rejecting foreign power and keeping our rituals. Given the above, the timing that Ganjae lectured in Mungyeong personally was a time that provided a clue to establish his core ideas. Nationally it was a time that must defend the country from foreign nations. Ganjae had faith that for keeping the country we must keep firmly our own rituals.

The purpose of this study was to examine the self-perceived fatigue among 262 dental hygiene students, who have recently experienced clinical practice. In this study, a structured self-reported questionnaire was used to assess and analyze the severity of fatigue among the population. This study was performed from January to September in 2013 to effectively encompass clinical practice. The results are as follows: The self-perceived fatigue of the subjects was significantly higher in a subjective unhealthy group than a subjective healthy group (p=0.000), in a group that was unsatisfied with their program than a group that was satisfied with it (p=0.000), in a group that had dissatisfaction in clinical practice than a group that had satisfaction with it (p=0.000), in a group that had over five weekly of clinical practice than a group that didn't (p=0.000), in a group that had more than 100 patients a day than a group that didn't (p=0.000), in a group that had conflicts between fellow staff than those who didn't (p=0.000), in a group that did not exercise regularly than a group that did (p=0.016). The result of using multiple regression analysis revealed that the variable factors affecting the degree of the self-perceived fatigue were; subjective health status, satisfaction with a clinical practice, the length of clinical practice, the number of patients, and staff conflicts. These variable factors have the explanatory power of 44.5%. In conclusion, to decrease fatigue and allow students in clinical practice to perform effectively, clinical practice educators need to actively participate as a community and develop programs that will decrease the fatigue of students. In addition, in-depth research is needed on the effects of outside factors and variables affecting fatigue.

This research intended to reveal the special characteristics of the vegetation structure and the tendency of change of -landfill slope districts, which are reclaimed land, through an investigationsinto the presently existent vegetation and plant community structure of the World Cup Park landfill slope district. For the analysis of changes in vegetation, this study compared the results of field surveys in 1999, 2003, 2005, 2007, 2008, 2012, 2016, and 2021. For the investigation into the plant community structure, a field investigation was carried out in 2021 with six fixed investigation districts designated in 1999 as subjects. To analyze the change in the plant community structure, the past data on the population, the number of the species, and the species diversity by the layer in 2021 were compared and analyzed in the landfill slope district, which is reclaimed land. The changes of the vegetation distribution and the power had been affected by typhoons (Kompasu). Above the plantation foundation, which had been dry and poor, Salix koreensis, marsh woody plants that had formed the community, decreased greatly. The Robinia pseudoacacia community, after the typhoon in 2010, decreased in the number of species and population. Afterward, it showed a tendency to rebound. Regarding the Ailanthus altissima-Robinia pseudoacacia-Paulownia tomentosa community, the number of the species and the population had shown a change similar to the Robinia pseudoacacia community. The Paulownia tomentosa and the Ailanthus altissima have been culled. The slope was predicted as a Future Robinia pseudoacacia forest. The Salix pseudolasiogyne community has been transitioning to a Robinia pseudoacacia forest. Only some enumeration districts, the Robinia pseudoacacia forests and the Salix pseudolasiogyne, had been growing. However, most had been in been declining. It was predicted that this community will be maintained as a Robinia pseudoacacia forest in the future. As these vegetation communities are the representative vegetation of the landfill slope districts, which is reclaimed land, there is a need to understand the ecosystem changes of the community through continuous monitoring. The results of this research can be utilized as a basic material for the vegetation restoration of reclaimed land.

In this study, we reviewed the preparation process and the main Uimul involved in the procession of Gyeongsang Gamsa Doim in the late Joseon Dynasty. We reviewed the Yeongyeong- Ilgi, written by Cho, Jae-ho, and the Miam-Ilgicho, wtitten by Yoo Hee-chun. Those who had been appointed as a Gamsa by the Sammang System went through the Saeun and Sajo procedures to thank and say goodbye to the king before leaving for his assignment. The Gyoseo and Yuseo were usually received from the king at this time, but in some cases, they were received in the Seungjeongwon, or the Seori of Seungjeongwon brought them directly to the place where the Gamsa works. The Milbu with the Eoab was received along with the Yuseol, and the principle was to return the Milbu later. The procession of Gamsa is divided into the pre-and post-Gyoinsik procession and the Sunryeok procession. It was confirmed that the pre-Gyoinsik procession was made more compact than the post-Gyoinsik procession. In the study, we reviewed Ilsan, which is necessary for the officials' procession, and also examined the Gyoseo, Yuseo, Jeol·Wol, and Milbu received from the king. We also looked at the Gwan-in and Byeongb given by the former Gamsa at the the Gyoinsik. The Jeol, which means the command and the Wol, which means killing power, were given to the Gamsa. And unlike previous studies, it was confirmed that the Jeol was a perforated hexagon and and the Wol was a trident. Also, it was found that Ilsan is white, and there are two rows of Yuso on each of the six ribs of the umbrella. It is thought that the results of this study, which looked at the Doim process and Uimul by dividing the Gyeongsang-Gamsa Doim procession in the late Joseon Dynasty pre-and post-Gyoinsik, will be helpful in understanding the process of Gasmsa Doim. In addition, it is expected that it can be used as basic data for reproduction event of traditional culture related to Gwana, such as the reproduction of Gyeongsang-Gamsa Doim-Sunlyeok procession and Gyoinsik.

Investors are trading stocks by keeping a close watch on the order information submitted by domestic and foreign investors in real time through Limit Order Book information, so-called price current provided by securities firms. Will order information released in the Limit Order Book be useful in stock price prediction? This study analyzes whether it is significant as a predictor of future stock price up or down when order imbalances appear as investors' buying and selling orders are concentrated to one side during intra-day trading time. Using classification algorithms, this study improved the prediction accuracy of the order imbalance information on the short-term price up and down trend, that is the closing price up and down of the day. Day trading strategies are proposed using the predicted price trends of the classification algorithms and the trading performances are analyzed through empirical analysis. The 5-minute KOSPI200 Index Futures data were analyzed for 4,564 days from January 19, 2004 to June 30, 2022. The results of the empirical analysis are as follows. First, order imbalance information has a significant impact on the current stock prices. Second, the order imbalance information observed in the early morning has a significant forecasting power on the price trends from the early morning to the market closing time. Third, the Support Vector Machines algorithm showed the highest prediction accuracy on the day's closing price trends using the order imbalance information at 54.1%. Fourth, the order imbalance information measured at an early time of day had higher prediction accuracy than the order imbalance information measured at a later time of day. Fifth, the trading performances of the day trading strategies using the prediction results of the classification algorithms on the price up and down trends were higher than that of the benchmark trading strategy. Sixth, except for the K-Nearest Neighbor algorithm, all investment performances using the classification algorithms showed average higher total profits than that of the benchmark strategy. Seventh, the trading performances using the predictive results of the Logical Regression, Random Forest, Support Vector Machines, and XGBoost algorithms showed higher results than the benchmark strategy in the Sharpe Ratio, which evaluates both profitability and risk. This study has an academic difference from existing studies in that it documented the economic value of the total buy & sell order volume information among the Limit Order Book information. The empirical results of this study are also valuable to the market participants from a trading perspective. In future studies, it is necessary to improve the performance of the trading strategy using more accurate price prediction results by expanding to deep learning models which are actively being studied for predicting stock prices recently.

People are destined to live according to the time and fate after they are born. Man is connected with the idea that is called the Chinese zodiac sign related to one out of 12 animals, regardless of one's thought. This paper was written with the expectation that it will be a new turning point understanding the mutual influence and its changing process by catching the ethnic belief and emotion as well as its cultural background in the Asian Zone by investigating the meaning of the 12 Chinese zodiac shown in the folk painting from the viewpoint of folk lore including "Chinese zodiac sign" culture rooted in our daily lives. The animal 'Rat' has been lived well human beings accompanied by the fable or the nature, while the animal 'Ox' has been living together with human history. The 'Tiger' has been considered the 'Power retreating disease or a devil' to humans, which is the most frightening but near at hand. The 'Rabbit' in the fable is inculcating hope and ideals to humans. The imaginary 'Dragon' is rooted in the deep national belief, which is seated as 'Guardian god' of farming culture and mankind, while the 'Snake' is playing a role in protecting humans as the 'Sea God' in Tsushima and Jeju Island, and has been believed and followed in the deep mind of humans. The 'Horse' in the nomad culture has been adorned as the basic creature of nomadic society in the character of a psychic medium between the human and god or their 'Guardian god'. The ancient Japanese regarded 'Monkey' as holy, being connected with treasure. It infers a human's desire to borrow wisdom from 'Monkey'. 'Chicken' includes the meaning of a lucky sign connecting the sky and the human world by arranging together with humans. The 'Dog' is believed and followed as performing the function of a messenger connecting this world with the afterlife in the next world tale of shamanism. The 'Pig' also lives well with humans, being interpreted as fecundity. Although the meaning of the 12 Chinese Zodiac animals has ethnic differences, all of them have been shared with humans, rooted in the human mind, being believed, and followed in human lives.
