  • This study is an attempt to explore the roles of and the collaborative relationship between Daheojang and Maedeupjang. Daheojang and Maedeupjang share a similar manufacturing process. However, in modern times, Daheojang totally disappeared, and Maedeupjang was designated as an intangible cultural property. The present study will investigate the role of Daheojang and Maedeupjang based on the literature of the Joseon dynasty. Daheojang were craftsmen who made bands and strings of woven or twisted silk strands. They made mangsu and tassels or made knots to produce magnificent artifacts. Maedeupjang complete all steps of the process, from refining, dyeing, combining threads, daheo, maedeup, to the tassel. Daheojang in the Joseon dynasty was the center of this process. Daheojang belonged to almost all Uigwe because it used items ranging from large uso to cushion straps. Dahoe is a craft with various items and techniques. It has been widely used to produce majestic items like formal dresses, ritual ceremony pieces, and mountings, as well as daily items like jodae, pocket straps, and norigae. Based on the records of Uigwe in the late Joseon dynasty, the study explored the collaborative relationship between Daheojang and Maedeupjang. Sambang, the room where both Daheojang and Maedeupjang belong, was the room to produce the royal chair. The royal chair essentially includes large uso. The large uso is an artifact that ties a knot in a thick circle more than two meters long. While Daheojang made rounded daheo, Maedeupjang made delicate and balanced knots. Also, they produced royal inscriptions together with a royal seal with decorative mangsu and a seal of thick rounded daheo. In order to learn about traditional technology, it is necessary to study the system of the times and social trends. Therefore, the study focused on Daheojang, who were common master craftsmen during the Joseon dynasty but now are not familiar to most people.

  • Gusadang Kim, Nak-Haeng is a scholar of 18th century in Yeongnam region who wrote about 130 Chinese poems. In this study, I searched Gusadang's inner world by interpreting his Chinese poems. His life is closely related to his father Jesan Kim, Seong-Tak who was exiled. The fact that he devoted himself to his father for 10 years shows he had strong standards in making decisions in life. In short, Gusadang was a person who looked gentle but was tough inside and he remained firm in his faith even with outside pressure. He could not achieve glory because he spent time serving his father in his thirties. Although he heard compliments from others that he was talented enough to succeed as a scholar, he lacked time and mental energy to study. Also, he was a moralist and wrote some poems about impressive events in his life even though he did not fully devote himself to writing poems. In this study, I searched his inner world focusing on how he felt and thought about outside world by analyzing his poems. In conclusion, I found three characteristics from his poems. Firstly, depressed feelings are shown based on excessive self-consciousness in the poems related to his father. Secondly, his will to keep balance in life is shown because he wanted a harmonious life as a seeker after truth. Thirdly, a sense of isolation is shown because he had to keep a distance from outside world.

  • This study aims to establish the floristic data and identify the useful plant resources of Mt. Ilimsan and its adjacent areas. The survey was conducted 27 times from March 31, 2020 to August 22, 2021. It identified 500 taxa consisting of 101 families, 304 genera, 444 species, 11 subspecies, 42 varieties, and 3 formas. A total of 853 plant specimens were collected. There were 16 taxa designated as endemic plants and 7 taxa designated as the rare plants by the Korea Forest Service, and 5 taxa designated as the red list plants by the Ministry of Environment. Moreover, the floristic target species by the Ministry of the Environment found in this mountain were 69 taxa, including 49 taxa for floristic degree I, 7 for floristic degree II, 11 for floristic degree III, and 2 for floristic degree IV. Biological resources subject to export approval by the Ministry of Environment were 159 taxa. The alien plants were 49 taxa, of which 5.6 percent were naturalized, and the urbanization index was 7.9 percent. Ecosystem-disturbing invasive alien plants designated by the Ministry of Environment were 6 taxa.

  • This study was designed to analyze the social and institutional problems that may arise in the early 2000s of the United States and in the scholarship program for university student-athletes by analyzing Dialogues in the Film [The Blind Side] and to derive the meaning of this to Korean society and education field. In summary, the first is that there is a need for fundamental change in the thinking about gender discrimination and racist expressions expressed in everyday life including a Sport field not only in the United states but also in Korean society. Second, the Korea University Sports Federation(KUSF), like NCAA, is working on the right to study and human rights of university athletes, but in the commercialism of modern sports related to the capitalism, these systems and regulations could be a bigger obstacle to the process of growing young players. And finally, like the case of "Flower-loving Ferdinand" who having a lot in common with the main character, Michael in the Film, I hope that there will be a "Sports Ferdinand" that likes the sport itself, which is fully satisfied with its life and lives happily even if it is not a sports star.

  • In field, one can observe without difficulties that two flocks are intersected or combined with each other. For example, a fish flock in a stream separates into two part by obstacles (e.g. stone) and rejoins behind the obstacles. The dynamics of two flocks guided by their leader were studied in the situation where the flocks cross each other with a crossing angle, ${\theta}$, between their moving directions. Each leader is unaffected by its flock members whereas each member is influenced by its leader and other members. To understand the dynamics, I investigated the order parameter, ${\phi}$, defined by the absolute value of the average unit velocity of the flocks' members. When the two flocks were encountered, the first peak in ${\phi}$ was appeared due to the breaking of the flocks' momentum balance. When the flocks began to separate, the second peak in ${\phi}$ was observed. Subsequently, erratic peaks were emerged by some individuals that were delayed to rejoin their flock. The amplitude of the two peaks, $d_1$ (first) and $d_2$ (second), were measured. Interestingly, they exhibited a synchronized behavior for different ${\theta}$. This simulation model can be a useful tool to explore animal behavior and to develop multi-agent robot systems.

  • The regions of Central Asia have each acquired an elevated strategic importance in the new security paradigm of post-September 1lth. Comprised of five states, Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan and Uzbekistan, Central Asia's newly enhanced strategic importance stems from several other factors, ranging from trans-national threats posed by Islamic extremism, drug production and trafficking, to the geopolitical threats inherent in the region's location as a crossroads between Russia, Southwest Asia and China. Although the U.S. military presence in the region began before September 11th, the region became an important platform for the projection of U.S. military power against the Taliban in neighboring Afghanistan. The analysis goes on to warn that 'with US troops already in place to varying extents in Central Asian states, it becomes particularly important to understand the faultlines, geography, and other challenges this part of the world presents'. The Kyrgyz military remains an embryonic force with a weak chain of command, the ground force built to Cold War standards, and an almost total lack of air capabilities. Training, discipline and desertion - at over 10 per cent, the highest among the Central Asian republics - continue to present major problems for the creation of combat-effective armed forces. Kyrgyzstan has a declared policy of national defence and independence without the use of non-conventional weapons. Kyrgyzstan participates in the regional security structures, such as the Collective Security Treaty Organisation (CSTO) and the Shanghai Co-operation Organisation (SCO) but, in security matters at least, it is dependent upon Russian support. The armed forces are poorly trained and ill-equipped to fulfil an effective counter-insurgency or counter-terrorist role. The task of rebuilding is much bigger, and so are the stakes - the integrity and sovereignty of the Kyrgyz state. Only democratization, the fight against corruption, reforms in the military and educational sectors and strategic initiatives promoting internal economic integration and national cohesion hold the key to Kyrgyzstan's lasting future

  • The world-wide cigarette market is becoming increasingly regulated. This involves restrictions on the freedom to advertise, restrictions on where people can smoke, and in some ways of most importance, limits on cigarette smoke deliveries. In particular, in an increasingly large number of countries maximum tar legislation is being enacted. In many cases, such as the European Union, this type of legislation is progressive and over time it is entirely conceivable that maximum permitted tar deliveries will be reduced to as low as 5 mg, possibly with additional restrictions on smoke nicotine deliveries. In addition, the pace of change is increasing as more and more countries embark on tar reduction programmes. The key challenge facing the cigarette industry is to manage these changes in such a way which ensures that product acceptability is maintained at as high a level as is possible in these circumstances. There are a number of ways of achieving this involving filter ventilation, modifying blends and using different filter constructions The real innovation comes when combining these in a way that gives the most acceptable balance of all these competing variables as far as the smoker is concerned. Undoubtedly, the nature of the filter is of crucial importance in designing the most acceptable low tar products, and this paper will discuss some of the filter types which are currently in use in the various low tar markets around the world. Also, some thoughts about the future in terms of new filter developments will be presented.

  • R&D (Research and Development) investment by companies and the government continues to increase, and the total R&D expenditure of public and private sectors in 2021 reached KRW 102 trillion, and the ratio of R&D investment to GDP was 4.96%. It ranks second in the world after Israel. This study analyzes the current status of the domestic R&D service industry and the research and development (R&D) innovation ecosystem based on the business activity survey data of the National Statistical Office in terms of improving R&D productivity of domestic R&D investment that has exceeded 100 trillion won, and analyzes the global R&D service industry and analyzes the global research service industry and R&D service Industry support government policy As a result of the analysis, in the domestic R&D ecosystem, the R&D outsourcing demand of service companies is rapidly increasing, compared to the stagnant R&D outsourcing demand of traditional manufacturing companies. In order to respond to these changing demands for technological innovation, this study suggests balanced support for R&D outsourcing for manufacturing and service companies, expansion of domestic R&D outsourcing, establishment of R&D outsourcing strategies specialized for the service industry, establishment of an open R&D ecosystem, and innovation in connection with materials/parts/equipment strategies.

  • The garment industry is one of the most labor-intensive manufacturing industries, with its sewing process relying almost entirely on manual labor. Its costs highly depend on the efficiency of this production line and thus is crucial to determine the production rate in real-time for line balancing. However, current production tracking methods are costly and make it difficult for many Small and Medium-sized Enterprises (SMEs) to implement them. As a result, their reliance on manual counting of finished products is both time consuming and prone to error, leading to high manufacturing costs and inefficiencies. In this paper, a production tracking system that uses the sewing machines' energy consumption data to track and count the total number of sewing tasks completed through Convolutional Neural Network (CNN) classifiers is proposed. This system was tested on two target sewing tasks, with a resulting maximum classification accuracy of 98.6%; all sewing tasks were detected. In the developing countries, the garment sewing industry is a very important industry, but the use of a lot of capital is very limited, such as applying expensive high technology to solve the above problem. Applied with the appropriate technology, this system is expected to be of great help to the garment industry in developing countries.

  • Ballast water provides stability and manoeuvrability to a ship. Foreign harmful aquatic organisms, which were transferred by ballast water, cause disturbing ecosystem. In order to minimize transference of foreign harmful aquatic organisms, IMO(International Maritime Organization) adopted the International Convention for the Control and Management of Ship's Ballast Water and Sediments in 2004. If the convention take effect, a port authority might need to check that ballast water is properly disposed of. In this paper, we propose a method of counting harmful aquatic organisms in ballast water thorough image processing. We extracted three samples from the ballast water that had been collected at Busan port in Korea. Then we made three grey-scale images from each sample as experimental data. We made a comparison between the proposed method and CellProfiler which is a well known cell-counting program based on image processing. Setting of CellProfiler is empirically chosen from the result of cell count by an expert. After finding a proper threshold for each image at which the result is similar to that of CellProfiler, we used the average value as the final threshold. Our experimental results showed that the proposed method is simple but about ten times faster than CellProfiler without loss of the output quality.
