In the Mobile IP, the movement of Mobile Host(MH) causes packets to be transmitted through a long route. A Correspond Node(CN) first communicate with a Home Agent(HA) when a Mobile Host moved from one subnet to another subnet. The HH-MIP algorithm reduces an inefficient transmission of packets by regarding a Foreign Agent(FA) near a mobile host as a Temporary Home Agent(THA). However, The algorithm costs the unnecessary signaling by measuring the distance of route between a FA and a THA for handover in the case that a Mobile host comes from a THA which a current FA never communicated. To solve this problem, we propose a scheme called Hierarchical Home Agent Handover in Mobile IP(HHH-MIP) algorithm. Our HHH-MIP algorithm only searches tables in a router by using the hierarchical structure between a FA and a THA. The simulation results show that the HHH-MIP algorithm reduces the additional signaling cost.

Since the introduction of carbonated drinks in the 1950s, 'cola' and 'cider'along with orange juice, the dominator of the juice market, have been two main streams of the Korean beverage market. This market pattern has caused the following effects; a. Economical loss due to the import of foreign brands - royalty payments to x company. b. Loss of opportunity to develop a domestic beverage market. c. Inflow of an unfiltered foreign culture. This study shows a change in the Korean beverage market. In the 1980s. consumers' tastes started to change as a trend of developing beverages using traditional Korean ingredients started to begin. On the basis of this change, I would like to discuss the desirable path in developing beverages using traditional ingredients. 'Traditional ingredients'refers to the ingredients that the Korean people have enjoyed within the course of their life, whether it be via food or beverage. These ingredients have been chosen by our people as first rate for centuries. How to modernize and develop these work-in-progress products is the desirable direction for the development of drinks using traditional Korean ingredients. This study also shows various examples of how Korean traditional ingredients and the Western scientific civilization can fuse together to develop a modern and value-added product. One project in particular, created a method of producing a beverage using rice a simple traditional ingredient, marking it a hit product. Through this example, I present the desirable direction of how to develop a modernized drink using traditional ingredients that can change both the consumers' current value on the Korean beverage market as well as create a new pattern of consumer tastes.

The purpose of this study is to verify whether the concept of time conveys meanings similar to nonverbal communicative elements in foreign language education. This study surveys cultural traits of time from the French cultural education perspective. Anthropologist Edward T. Hall points out that each cultural community has developed a different perception of time and experience, and that time conveys the meaningful message nonverbally similar to the nonverbal elements such as space, gesture, eye movement, and facial expression. I investigated the time experiences of a drinking party in France and in Korea, from a cultural relativistic point of view. The subject of a drinking party was chosen on the ground that a drinking party is highly related to most people's daily lives and it also indicates how they have a relationship with others. I sought a new direction in foreign language cultural education by analyzing how cultural differences between the two communities, especially the relationships between individuals and organisations, ways to separate leisure and labor, and the nonverbal elements, are presented in the two drinking parties.

A power tool is a tool used to manufacture and process various structures using a motor that is a power source. Using a motor that uses electricity as a power source, a reduction device, power transmission and conversion device functions are built-in to make the tool rotate, reciprocate, and vibrate. It is a work tool designed to assist the user's movement skills. In the case of Korea, the power tool industry has a short history and is lagging behind advanced countries such as Germany, the United States, and Japan in terms of technology level, market share, and recognition. In addition, electric drivers used in Korea are foreign products from the US and European countries, and the domestic market also prefers 100% foreign companies, and multinational companies are investing a lot in the domestic market. Therefore, technological development must follow in order to develop domestic technology and secure a consistently high market share. The purpose of this thesis is to design a motor driver with high output performance of motor performance, miniaturization, and high speed in accordance with the basic performance requirements of power tools, and finally research developments that can be applied to industrial and medical applications.

The South Korean ethnic diaspora US lobby shows efficacy as an interest group in generating influence in American foreign and domestic public policy making. The persuasive portrayal of South Korea as a critical Cold War US ally reinforced US amenability to pro-South Korea lobbying. Also, the South Korean US diaspora is a comparatively recent immigrant group, thus its lingering resistance to assimilation facilitates its political mobilization to lobby the US government. One source of this influence includes the foundational legacy of proselytizing Western and particularly American religious social movement representatives in Korean religiosity and society. US protestant Christianity acquired a strong public association with emerging Korean nationalism in response to Japanese imperialism and occupation. Hostility towards Japanese colonialism followed by the threat from Soviet-sponsored, North Korean Communism meant Christianity did not readily become a cultural symbol of excessive external, US interference in South Korean society by South Korean public opinion. The post-Cold War shift in US foreign policy towards targeting so-called rogue state vestiges of the Cold War including North Korea enhanced further South Korea's influence in Washington. Due to essential differences in the perceived historical role of American influence, extrapolation of the South Korean development model is problematic. US hegemony in South Korea indicates that perceived alliance with national self-determination constitutes the core of soft power appeal. Civilizational appeal per se in the form of religious beliefs are not critically significant in promoting American polity influence in target polities in South Korea or, comparatively, in the Middle East. The United States is a perceived opponent of pan-Arab nationalism which has trended towards populist Islamic religious symbolism with the failure of secular nationalism. The pronounced component of evangelical Christianity in American core community nationalism which the Trump campaign exploited is a reflection of this orientation in the US.

Jeju Island is a major area generates origin-destination trips, accounting for about 90 % of domestic air transportation, and popular tourist destination visited by more than 10 million domestic and foreign tourists annually. Travel behavior patterns of tourists in Jeju Island have great meaning for not only Jeju Island, but also the inland aviation, tourism, mobility industry. This study presented passenger travel behavior in Jeju Island based on a survey including foreign visitors and residents as well as domestic visitors. In particular, the survey was conducted in early 2020 prior to the COVID-19 pandemic, it is expected to be a major preliminary study for changes in tourist travel and air travel in Jeju Island before and after COVID-19.

There are many modern elements in religions appeared in the early Korean modern era. From the nationalism perspective, most religions had tendencies toward anti-feudalism and anti-foreign power. Pak Eun Sik(朴殷植) emphasized the importance to explain those religions as the National Religion in his writing 《Korea Painful History(韓國痛史)》. That is, he realized those as one of Korean spirits or souls keeping Korean identities like the Jew's Judaism or the Turk's Islam. In the paper, I try to analyze religions on Kang Jeung San(姜甑山) with Daesoonjinri-hoe as the central figure from Pak's perspective. In the early Korean modern era when Kang went his own the Savior way, Korea and its society got into uncontrollable confusion because of strong demands both of a feudal-state breaking and against pillaging foreign-power especially Japan. For all countries of the world, it is difficult to change from a feudal state into the modern nation state to keep existing society order. Because the reformation under old social systems means the incomplete reformation. So in this era new religions showed the neglected class of people the vision of new society. Meanwhile Korean society try to become a modern state, and now became a recognized modern state in international society. But it is still insufficient to debate on groups and their roles for Korea modernity in that time especially new religions. Since Korea independence, new religions including Daesoonjinrihoe have not receive good reviews because of a certain religion group expansion and the government's regulation and control toward new religions. Till today, I think, Independence Movement as well as reform of modern awareness have not relatively receive reasonable reviews. So I hope to serve as a momentum that in early Korea modern era new religions receive reasonable and positive reviews.

The Gyeongseong Women's Medical Training Center was created as the result of the efforts of our internal visionaries with meaningful foreign missionaries to cultivate female doctors, yet the systematic structure of the institution developed primarily out of Korean efforts. Koreans have tried hard to cultivate their descendants and the skills of the Korean people within this framework, challenging the oppression of the ruling class in a given environment, and the results have continued to this day. First, during the Early period (1890-1909), Korea began to establish women's education and the first female doctors were trained with the help of foreign missionaries. Second, during the Growth period (1910-1919), while it was difficult for women's education to be easily expressed during Japanese colonial era, the need for women's education was growing as part of the patriotic enlightenment movement, and female students who wanted to become doctors began to go abroad. In addition, during this period, the means to train female doctors in Korea was available, but this system was not recognized by the Japanese colonial government. Third, during the Preparatory period (1920-1928), the Gyeongseong Women's Medical Class, which gave practical training to female doctors, was established and centered on Rosetta Hall and female doctors who studied abroad. Fourth, a women's medical school was established during the Establishment period (1929-1938), which created a foundation for stable supply of professional women's medical personnel. In this article, we studied the process of women who were marginalized in education until they were trained as professional intellectuals, and we hope that it will help them understand the current women's education in Korea and draw directions in the future.

The nasal cavity encounters various irritants during inhalation such as dust and pathogens. To detect and remove these irritants, it has been postulated that the nasal mucosa epithelium has a specialized sensing system. The oral cavity, on the other hand, is known to have bitter taste receptors (T2Rs) that can detect harmful substances to prevent ingestion. Recently, solitary chemosensory cells expressing T2R subtypes have been found in the respiratory epithelium of rodents. In addition, T2Rs have been identified in the human airway epithelia. However, it is not clear which T2Rs are expressed in the human nasal mucosa epithelium and whether they mediate the removal of foreign materials through increased cilia movement. In our current study, we show that human T2R receptors indeed function also in the nasal mucosa epithelium. Our RT-PCR data indicate that the T2R subtypes (T2R3, T2R4, T2R5, T2R10, T2R13, T2R14, T2R39, T2R43, T2R44, T2R 45, T2R46, T2R47, T2R48, T2R49, and T2R50) are expressed in human nasal mucosa. Furthermore, we have found that T2R receptor activators such as bitter chemicals augments the ciliary beating frequency. Our results thus demonstrate that T2Rs are likely to function in the cleanup of inhaled dust and pathogens by increasing ciliary movement. This would suggest that T2Rs are feasible molecular targets for the development of novel treatment strategies for nasal infection and inflammation.

It was the year of 1903 when avantgarde artists in Vienna gave a birth to the Wiener Werkstaette under the influence of Aesthetic Movement and Guild of Handicraft from England. This study is on the backgrounds of the birth of the Wiener Werkstaette its artis-tic motto and world-wide echo it provoked. This thesis goes back to the time when the decadent Wiener Secession shaped up refiewing the Reform Movement It also covers characteristics works of major members of the Wiener Werkstaette which were produced on the basis of the concept of Gesmtkunstwerk, The conclusion of this study is that : 1. Without losing its own specifc features various fields of formative arts were combinded together coherently and succeeded to realize the idealistic art that is the com-posite are 2. The Wiener Werkstaette was strongly opposed to the ready-made clothes which be-came popular as the society was Industrialized and commercialized. unlike those ready-to-wear clathes those members of the Wiener Werkstaette preferred to make each clothes with different mateirals and printed their own unique pattern designs. 3.As a results of close relationships between the Wiener Werkstaette and paul poiret 'Stu-dio Martine' was established in paris and new pattern deslhns were introduced by Raoul Dufy. 4. After the break-out of World War One cultural exchanges with other foreign countries were vuirtually cut off and the Wiener Werkstaette was disconnected from the influence of Parisl That was the motive for Wiener Werkstaette to start building up its unique artistic style with peculiar materials techniques and methods of productionl Those brisk and creative activities of the Wiener Werkstaette brought forth "the Golden perlod of 1920s" 5. Its historic design and ornamental pattern were assessed as a prelude to the Post-mod-ernism Since the late 1970s with the redis-covery of the culture of vienna in 1900s. the Art to wear which was created by the 'Wiener Werkstaette' but unfortunately tucked away by the Greate Depression and nationalism has been revaluated and studied. In Korea it was since 1985 when 'the art to wear' began to gain attention widely. It is urged that the theory of the 'Gesamtkunstwerk' should be also ac-cepted and shared earnestly.
