Prolotherapy can be defined as the injection of growth factors or growth factor production stimulants to grow normal cells or tissue. Even though it has been a controversal procedure for decades, it is currently gaining in popularity among many physicians. The term prolotherapy was coined by Hacket in the 1950s to imply proliferation of normal tissue at ligamentous and tendinous entheses. The procedure has been described by other terms, such as sclerotherapy, regenerative injection therapy, and stimulated ligament repair. Incomplete healing from sprains or strains is common and can lead to chronic pain, joint instability and laxity, and is a risk factor for the development of osteoarthritis. Prolotherapy is commonly used for these musculoskeletal conditions which are refractory to usual care therapies. The proliferant solution and technique varies according to physicial training and preferance. Commonly reported proliferants include 10% to 25% dextrose, P2G and sodium morrhuate. High resolution ultrasound imaging of musculoskeletal tissue is increasing in popularity because of patient tolerability, low cost, ability to visualize tissue in real time motion and superior resolution of highly organized tissue such as a tendon. This procedure can be introduced by ultrasound imaging and tissue growth and repair after this procedure in a tendon or a ligament can be documented with ultrasound.

There have been research and studies on rumble strip effectiveness in terms of accident reduction since rumble strips were first installed in 1950's. Research has shown that rumble strips reduce accidents from drowsy and inattentive driving. The present research statistically analyze the accident reduction effect of rumble strips based on accident reports obtained from rumble strip installed 377 places of nation wide freeway lines. Based on the results, rumble strips are effective in reducing accident frequencies 32.3%. The probable various factors inducing accidents are identified. These include drowsiness, speeding, inattentiveness, vehicle defectiveness, and short headways. It was found that rumble strips are effective in reducing A, B, C leveled accidents, and in reducing clear, cloudy, and rainy weather accidents. The results may make clear and expand probable types of accidents that rumble strips would reduce, then reduce the total accidents on freeway lines.

Conceived to acquire personal information for an electronic medical record, the clinical interview contains probing questions. The number and type of inquiries are assumed to fulfill medical protocols, and therefore are deemed essential for treatment - but the rate can and should be controlled. High rates of inquiry merely intimidate the patient and affect replies. The purpose of this paper is to mathematically formulate permissible rates of clinical interviews held during telehomecare virtual visits and designed to avoid patient anxiety. Mental stress is derived as a function of the weight of importance assigned by the patient, virtual visit duration, and the rate of questioning in the direction of greater sensitivity. Two operations are of interest: Collecting and recording information by the provider, and maintaining synchrony of questions and answers by the patient. The Lorentz transformation yields the patient’s view of the operational rates. Conservation of information momentum is postulated and applied before and after replies are recorded. It is shown that the weight of importance designated by the patient to collecting and recording personal information is driven by a singularity that depends on the rate of questioning. The findings should serve as a guideline in interviewer training programs.

In the 1950’s, after modernistic hospital is begun to build in our country, there were much changes in hospital construction plan such as function, scale, operation, technology for 40 years so far. Interest about 'Healing environment furtherance' which is one of basic function of hospital within these change is continued. Specially, concept about furtherance of healing environment limited in ward department in the early time is applied to hospital space magnificently whole coming at present. Entrance of hospital and change of Lobby may speak as the representative example. This interest about practically use of lobby is rising gradually. Lobby adds to existed concept of space to the importance revaluated. The first purpose of this study is to investigates main entrance and lobby of representative hospital in our country and to search change and present condition.

In this paper, design specifications for a new generation container crane in year 2013 is investigated. After analyzing the trend of the development of container cranes from the 1950s to date, a prospective size for targeting year 2013 is proposed. Introductory specifications of the frame, trolley, hoist and spreader for the proposed new crane are discussed. Considering that the mega-ships will load and unload more than 15000 boxes at one stop, rough dimensions of the crane including outreach, rail gage, lift, backreach, etc. are also suggested. Although the sheer size of the cranes already present some challenges, the biggest challenge is to improve productivity by maximizing the moves per hour. For this, the speeds of trolleys and hoists, rail loads, stability, etc. are discussed.

After the outbreak of the Korean War on June 25, 1950, the US included the Republic of China on Taiwan (Taiwan hereafter) in its Asia-Pacific containment line, and restored the military and economic aid to Taiwan for the sake of regional security. The US aid to the countries along the Asia-Pacific defense line was not only in the form of supplying munitions, but also linked these countries together in an economic dimension. Taiwan is one of the 120 countries which had accepted US aid and also successfully moved from "dependence" to "independently sustained growth." This article will firstly review the historical background of US aid to Taiwan and related institutional development; secondly, this article will illustrate how Taiwan used US aid, and which economic sector the US aid affected; thirdly, it will trace the impact of US aid on Taiwan's foreign trade, and finally, to make a conclusion.

After 1950's, criticizing uniformity of modem architecture, a number of architectural theories and works which represet the identity of each region have appeared. However it is not a systematic theory but an attitude which approaching to design rather than new architectural trend or theory. Therefore, the thesis studied the general concept about regionalism and analyzed of the City Hall showing the regional identity. Finally this study intend to explain the detailed method of expressing regional identity created by architects by investigating the formal characteristics of regionalism and relationship with various context.

'Inha University' (Inha Institute of Technology) was founded on April 1954. The establishment of Inha University has several special meanings. First, I tried to examine the establishing process of Inha University in the context of emigrations and nationalist movements. Inha University was established to commemorate the 50th anniversary of emigration to Hawaii, with the seed money of $150,000 which came from the sale of 'Korean Christian Institute' in Hawaii. Korean Christian Institute had taken charge of teaching the children of Korean residents in Hawaii. Rhee Syhngman, the fist president of Republic Korea was the leader in founding Korean Christian Institute and Inha University, but behind him there were donations of both Korean residents in Hawaii and common Korean people of the 1950's. The establishment of Inha University has a nation-wide and national meaning in that the spirit of nationalist movements in Hawaii and donations of Korean people at home and abroad were linked together. Second, I tried to examine the economic and educational policies after the liberation in 1945. In the 1950's Korea planned to set up self-supporting economy with the aid of America. Accordingly, the educational policy had to be considered in view of economic independence, too. 'Inha Institute of Technology' was the result of these national economic and educational demands. Consequently Inha Institute of Technology took a special position of carrying out national policies with the intervention and protection of the Government, including the president Rhee Syungman in person, even though it was neither national not public but private college. Third, I tried to examine the local history of Incheon. How did Inha Institute of Technology come to be built in Incheon? That's because the emigrant ships departed from Incheon. For those Korean emigrants, it is quite natural that the city of Incheon has a symbolic and commemorative meaning. In addition, Incheon is a port city neighboring the capital Seoul and has 'Seoul-Incheon Industrial Complex' in it. Graduates from Inha Institute of Technology were expected to act as competent scientists and technical leaders of that complex. Really Inha Institute of Technology trained many a good technicians with short-term courses and re-educated them after. The history of university has been usually underestimated as that of mere institution. In dealing with the history of Inha University as an example, I tried to re-examine the history of university in the context of Korean history and to emphasize the importance of keeping any all records relating universities.

North Korea's traditional dress(chosun-ot) has developed as follows: right after the liberation(l945). North Korea tried to get rid of Japanese style and empty formalities and vanity, so chosun-ot became simple and practical. And from the Korean war to 1950's North Korea had tried to establish through a restoration of the war and chosun-ot is more easy and simple. For 1960's People became to be interested in their clothes owing to a stable socialistic economy and politics, and tried new style due to the influence of the Korea-Japanese. Since 1972 North Korea has claimed a dictational socialist organization, and constructed its own culture. Therefore North Korea emphasized its own clothing habit. and its garment style developed differently from South Korea. Since 1984 North Korea tried to change its policy dramatically. and chosun-ot has changed to a modern and various style. But on the other hand, traditional style of chosun-ot was more emphasized. North Korea especially tried to succeed its traditional style. it pursued only partial changes by sticking to its original style. And its color to bright and magnificent one with additional ornaments. Because it tried to change the style within the limits of its tradition, traditional dress has a quite fragmentary and flat appearance.

This study examines the rural village planning in North Korea after the Liberation of Korea in 1945. For conducting this study, the creation of rural villages in North Korea were investigated according to the following periods: from the Liberation of Korea to the outbreak of the Korean War, from the end of the Korean War to the 1950's, 1960's, 1970's and 1980's. In this study, major rural villages were also examined and common characteristics of rural village-making in North Korea were analyzed. The following are the findings from this study. In rural village planning, historic revolutionary sites and buildings, where revolutionary achievements of Kim, Ill-Sung and Kim, Jung-Ill were reached, are well preserved and actively created. (2) Rural villages are intended to be a place for ideological education, productive activities and cultural refreshment. (2) In rural village-making, inclined planes are utilized, in consideration of climatic and topographic conditions. (4) The construction of residential areas with modern private houses is considered to be important in the making of socialistic and communist rural communities in North Korea. (5) For economic reasons, existing villages, buildings and facilities are preserved and local building materials are broadly used.
