Background: Farinelli breathing (FB) exercise is a typical breathing exercise used by singers. This study aimed to compare effects of FB exercise and diaphragmatic breathing (DB) exercise on respiratory function and symptoms in patients with chronic obstructive pulmonary disease (COPD). Methods: Sixteen patients aged 51-80 years with mild or moderate COPD were recruited for this study. They were divided into two groups: DB group (n=8) and FB group (n=8). Both groups received complete breathing exercise training five times per week for 8 weeks. Their respiratory functions, COPD symptoms, cytokine levels, and oxidative stress variables were analyzed during pre- and post-tests. Dependent variables were compared between pre- and post-tests using paired t-tests. An independent t-test was used to compare variables between the groups. Differences were considered significant at p<0.05. Results: The maximal expiratory pressure (MEP), maximum oxygen consumption (VO2max), and COPD Assessment Test (CAT) scores changed significantly in the DB group after the 8-week intervention compared to those at pre-test, whereas force vital capacity, forced expiratory volume in the first second, maximum voluntary ventilation, maximal inspiratory pressure (MIP), MEP, VO2max, CAT score, tumor necrosis factor-α, and malondialdehyde level changed significantly in the FB group at post-test compared to those at pre-test. Moreover, both MIP and MEP in the FB group were significantly higher than those in the DB group. Conclusion: FB exercise improved respiratory functions and COPD symptoms of patients with COPD. It might be an alternative breathing exercise in pulmonary rehabilitation programs for patients with COPD.
Purpose: This study aimed to investigate the potential factors that could affect the reduction rate of odontogenic cysts following decompression using cone-beam computed tomography (CBCT) for 3-dimensional volumetric analysis. Materials and Methods: The study sample consisted of CBCT images of 41 individuals who underwent decompression of odontogenic cysts at the Department of Oral and Maxillofacial Surgery, Faculty of Dentistry, Chulalongkorn University, between 2010 and 2022. Preoperative and postoperative CBCT results were collected, and a volumetric analysis was conducted to evaluate the differences in the reduction rate and the percentage of volume reduction of cystic lesions based on different parameters. Correlations between these parameters were analyzed to determine associations. Results: In this study, the average time of decompression for odontogenic cysts was 316 days. Males demonstrated a higher reduction rate than females (P<0.05). The reduction rate was directly proportional to initial cyst volume, with higher reduction rates for cysts with large initial volume than those with small initial volume (P<0.05). Spearman's rank correlation coefficient indicated a weak positive correlation between the initial cyst volume and the duration of decompression. Additionally, a strong positive correlation was observed between the initial volume and the reduction rate. Conclusion: Knowledge of the reduction rate of odontogenic cysts is vital for surgeons to evaluate the duration of decompression before enucleation and to determine a definitive treatment plan. Sex and initial lesion volume had significant effects on the reduction rate.
In the development of linear perspective, Brook Taylor's theory has achieved a special position. With his method described in Linear Perspective(1715) and New Principles of Linear Perspective(1719), the subject of linear perspective became a generalized and abstract theory rather than a practical method for painters. He is known to be the first who used the term 'vanishing point'. Although a similar concept has been used form the early stage of Renaissance linear perspective, he developed a new method of British perspective technique of measure points based on the concept of 'vanishing points'. In the 15th and 16th century linear perspective, pictorial space is considered as independent space detached from the outer world. Albertian method of linear perspective is to construct a pavement on the picture in accordance with the centric point where the centric ray of the visual pyramid strikes the picture plane. Comparison to this traditional method, Taylor established the concent of a vanishing point (and a vanishing line), namely, the point (and the line) where a line (and a plane) through the eye point parallel to the considered line (and the plane) meets the picture plane. In the traditional situation like in Albertian method, the picture plane was assumed to be vertical and the center of the picture usually corresponded with the vanishing point. On the other hand, Taylor emphasized the role of vanishing points, and as a result, his method entered the domain of projective geometry rather than Euclidean geometry. For Taylor's theory was highly abstract and difficult to apply for the practitioners, there appeared many perspective treatises based on his theory in England since 1740s. Joshua Kirby's Dr. Brook Taylor's Method of Perspective Made Easy, Both in Theory and Practice(1754) was one of the most popular treatises among these posterior writings. As a well-known painter of the 18th century English society and perspective professor of the St. Martin's Lane Academy, Kirby tried to bridge the gap between the practice of the artists and the mathematical theory of Taylor. Trying to ease the common readers into Taylor's method, Kirby somehow abbreviated and even omitted several crucial parts of Taylor's ideas, especially concerning to the inverse problems of perspective projection. Taylor's theory and Kirby's handbook reveal us that the development of linear perspective in European society entered a transitional phase in the 18th century. In the European tradition, linear perspective means a representational system to indicated the three-dimensional nature of space and the image of objects on the two-dimensional surface, using the central projection method. However, Taylor and following scholars converted linear perspective as a complete mathematical and abstract theory. Such a development was also due to concern and interest of contemporary artists toward new visions of infinite space and kaleidoscopic phenomena of visual perception.
A growing interest in health has been leading to more interest in function of food rather than its taste and nutrition. Usually we think chemical-free or oriental food to be good for health. Yaksun is a food with herbal stuff, which reflects our desire for health and longevity and China's splendid food culture. It is based on the traditional medical thought of the Orient that both medicine and food have the same origin. Yaksun is a traditional functional or nourishing food with both nutritive and medicinal elements, which therefore provides such effects as epicurean pleasure, prevention of diseases and improvement of health. It is recorded that in China there was a dietitian in the royal court from the period of Seoju(B.C. 11∼7), who was responsible for supervising and controlling the health, nutrition and disease of an emperor. Therefore, herbal food has a very long history. Currently, there are many Yaksun stores in Japan and Taiwan as well as China, which are one of popular tourist destinations. Basically Yaksun follows the theory of the Oriental medicine. Yaksun is categorized into four(cold, cool, hot and warm) according to its temperature and into five basic tastes(bitter, sweet, pungent, salty and sour). Yaksun has the functions such as preventing diseases and aging improving internal organs, and healing diseases. In China many colleges of medicine have a department of Yaksun studies through which systematic researches have been being made since a long time ago. For Korea, the discipline of Yaksun studies is still at the beginning stage. To respond to a growing interest in health and prevent chronic adult diseases, it is required to develop a functional food by establishing a systematic theory of Yaksun and making more researches into it.

The purpose of this study is to examine how the cultural aspects of the publication of literary collections have been changed from its time throughout the entire Joseon Dynasty. At the royal court in the early Joseon Dynasty, the need for publication of the literary collections has consistently arisen to preserve writings of the noted sages, and the Joseon government was also taking the lead and promoting the publication of the literary collections. From the 16th to the early 18th century, the publication was intensively made at the local governments led by local governors. From the 17th to the early to middle of the 18th century, the finances of local governments were limited with the changed taxation system, and there had been a dramatic decrease in the number of literary publication projects. On the other hand, with the sudden increase of the number of Seowons during the reign of King Sukjong, the focus of the literary publication was moved to Seowon from the 18th to the 19th century. After the enforcement of the Seowon Abolition Decree, the collections were still published at Seowons, however from the end of 19th century, the publication of literary collections had been explosively made by aristocrats who did not belong to the institution of Seowon or could not receive Seowon's support, which spreaded over the entire Yangban culture.

The Mangi yoram("萬機要覽"), a guidebook of state affairs, was published by royal command in the late Joseon period. Its chapters on financial affairs(財用篇) are particularly remarkable, as they explain on all aspects of the national finance of the late Joseon period in a clear manner. The financial part of the Mangi yoram includes metallic mineral resources, such as the location of gold, silver, copper, lead deposits and the prosperity and decline of the mines, and the various uses of each of the minerals. These are still regarded as valuable resources. Its contents on agricultural geography comprise not only the total yearly output of grains, paddyfields and dryfields, their taxation and standards of taxation, but also ginseng which was famous in the outside world in the pre-modern era. The book also clearly explains distribution of agricultural dikes for irrigation and their functions. The book also contains information on forestry geography, e.g. the varieties of pine trees and their distribution and mountain containment policies. Contents related to commercial geography consist of material on different types of markets such as the yukuijeon(六矣廛), sijeon(市廛), peongsisuh(平市署), nanjeon(亂廛), and the distribution, size and prosperity and decline of the border markets of the northern frontier such as the hoeryungkaesi(會寧開市) and geongwonkaesi(慶源開市). Contents related to transport geography are the distribution and functions of government granaries etc. Obviously, this book contains detailed information on various aspects of Korean geography. If we try to understand the contents of this book from the framework of modern geographical classification schemes, the geographic information contained in the book assumes even greater significance. In sum one may conclude that this book, which the king kept by his side, contained useful geography related knowledge and necessary information, and was directly relevant to the administration of the country. It exerted immense influence on the contemporary intellectual world of Joseon Korea, and was regarded as an invaluable resource.
In the highly competitive and divers world of financial market, customer is the single most important factor to company's survival. Especially, creating a relationship with valued customers is a key to success. CRM provides the mean to retain high value customers. It takes a prospect of what customers expect. Utilizing those knowledge can help the products and service meet the customers' needs, thereby maximizing customer satisfaction and company's profit. In this report, I am going to suggest a few ways to develop successful CRM in the life insurance industry. First, CRM should innovate the way of communication to keep pace with Web 2.0 era. In other words, the customer's needs should be caught by real-time communication than traditional off-line market research. Thus, the functionality and specification of products can be decided by customer's direct choice so that the customers are able to purchase the understanding and experience of the products. Second, CRM project should consider whether the initial strategy plan can promise the stable growth of customer at the first step. When planning strategy, the project needs to identify what customer wants and how to fulfill the needs with stable growth of the customer. In addition, the CRM should be developed by realizing that customer centric benefits ultimately guarantee the growth of the organization. Third, CRM systems should enhance the organization's ability to take the customer's insight in a 360 degree view and to capture the voice of the customer directly. In order to develop the best matched product package, more precise customer segmentation should be ahead of market segmentation strategy. Forth, the biggest reward from CRM will be a customer royalty program. Many successful banks are already planning and practicing customer royalty strategy. A comprehensive analysis of customers and their behavior allow organization to identify high value potential customers' needs and determine a strategy required to meet those needs. Even life insurance companies such as Prudential Korea are developing products designed for royal customers. Fifth, understanding and managing the experience of customer called Customer Experience Management also can increase customer satisfaction. Measuring only customers' experience and adapting it to marketing strategy make products position in the gap between the customers' expectation and experience not required by market. A key component of CEM is its application across all organizational functions. At last, the direction of change and development of CRM can be defined from the conceptualization of information technology represented by Ubiquitous and Web 2.0. Instead of just managing customer information, companies should take the initiative in personalized system with customer oriented strategy. Furthermore, with the regular communication between CRM stakeholders (Sales-Marketing-IT), customer's demand should be directly reflected to enterprise strategy in real time.

When the Yongle Emperor of the Ming Dynasty seized the power as the emperor of China, he issued a royal order to Hokwang and others, to publish a book entitled "Sambudaejeon," in the name of following the death-bed instruction of Taizu. The book was completed no less then 10 months after the order was issued in September 1415(Yongle 13). With the first copy imported from the Ming Dynasty as the original script, Sambudaejeon was engraved on wood by going sharing with 3 provinces including Gyeongsang-do, Jeonlla-do, and Gangwon-do, during the period of 1427~1428(Sejong 9~10). The result of surveying and analysing the distribution of the Ming Dynasty was imported to Chosun, shows that the engraving copy of the original script from the Ming was published more then 18 times in Chosun, among which only 50 types are identified to exist currently. As a result of analyzing these 50 existing types, This status of publication suggests that the books were intensively published and distributed in Gyeonggi and Gyeongsang provinces where the demands for the books were urgent, to meet the needs when the books were rapidly lost during the period of Japanese invasion.
This essay traces the origin and the social function of medieval knights in Edwin Austin Abbey's murals ${\ll}$The Quest of the Holy Grail${\gg}$ in the Boston Public Library. Medieval knights in the Arthurian legend appeared in American novels at the end of 1850s and in political cartoons in the 1870s. They are featured in American Renaissance murals as well. ${\ll}$The Quest of the Holy Grail${\gg}$ painted in 1895 was the first of its kind. In Britain, the Pre-Raphaelites frequently painted medieval knights. Abbey fused the visual idiom of the Pre-Raphaelites and that of the Royal Academy of Arts in his depiction of knights. Unlike the Pre-Raphaelites, who usually focused on knights' activities, he emphasized their virtue. His representation of knights reflect the social and economic crises in America in the 1890s. After the Civil War, American society enjoyed economic prosperity but suffered from government corruption, economic inequality, and class conflict. Serious social problems such as poverty and inequality decayed American society. Writers and artists brought attention to these issues. This essay argues that Abbey criticized capitalists and expressed his hope for progress through the figure of Galahad as the iconic representation of civic virtue in ${\ll}$The Quest of the Holy Grail${\gg}$. Installed in the Boston Public Library, Abbey's murals performed a public function to warn the viewers of economic and social chaos resulting from government corruption. Abbey's American knights not only emphasized moral responsibility but also promoted patriotism. The artist refashioned medieval knights into American citizens, whose civic virtue became essential to an ideal leader in American society.
This study looked into the process by which Haseo(河西) Kim In-hoo(金麟厚:1510~1560), a neo-confucian scholar of mid Joseon Dynasty, was recognized and adored as an inheritor of traditional academic genealogy of neo-confucianism of Joseon Dynasty. I intended to examine the process of personal embodiment affected or excluded in certain manners by various materials covering the lifetime of bygone persons based on the process of such embodiment. The part related to childhood of Haseo was arranged newly to highlight solid relationship between Kim In-hoo and King Injong(仁宗). That was because Kim In-hoo raised the issue of loyalty and fidelity, one of the most important and most contentious issues at that time, in connection with reinstatement of GimyoSarim(己卯士林, progressive political faction with young officials), and King Injong was the king who reinstated Gimyo Sarim. That played a decisive role in establishing the image of Haseo, a classical scholar with unwavering integrity and loyalty. During the Late Joseon Dynasty, canonization of Haseo was made under the leadership of King Jeongjo(正祖) and Seoin(西人) in royal court. In the 17th century, Seoin scholars revised the materials related to lifetime of Kim In-hoo in various way and proofread and published the collection of literary works by Kim In-hoo. That aimed to establish scholastic system associated with Seoin and legitimacy of study as pursued by Seoin. This made progress with adoration towards scholars affiliated with Seoin, including Yulgok(栗谷) Lee Yi(李珥). Finally, King Jeongjo showed strong intention to take the lead as sovereign in the process while Haseo was canonized into national academy in the 18th century. That came from the desire to solidify his status as a teacher who took pride in taking responsibility for the dynasty's authentic study, as well as the king heading the dynasty politically.
