  • 본 논문에서는 OADF(Opportunistic Adaptive Decode-and-Forward) 릴레이 시스템에 대한 새로운 성능분석 기법을 레일리 페이딩 채널에 대하여 제안하였다. 제안된 분석 기법에서는 릴레이들의 복호 오류 사건(error-event)을 기반으로 수신된 순시 신호대 잡음비(Signal-to-Noise Ratio: SNR)를 표현한다. 또한 SNR의 확률 밀도 함수(Probability Density Function: PDF)를 기존의 분석 기법보다 일반적인 (PDF 표현에서 합 기호의 개수 및 그 영역이 구체화된)형태로 제시한다. 그리고 이를 이용하여 정확한 평균 오류율((Average Error Rate), 누락 확률(Outage Probability) 및 평균 채널용량(Average Channel Capacity)을 일반적인 형태로 유도한다. 제안된 성능분석 기법의 정확성은 모의실험을 통하여 검증한다. OADF 기법을 다른 기법들과 비교하여 평균 오류 확률, 누락 확률 및 채널 용량 측면에서 성능 향상 정도가 우수함을 확인하였다.

  • 건설 클레임은 여러 가지 원인에 의해 야기되지만 선진국의 경우 대부분의 클레임에서 가장 근본적인 문제는 공기지연이며, 국내의 경우에도 이로 인한 분쟁이 증가할 것으로 예상된다. 이와 같이 건설공사에서는 공기지연으로 인해 발생하는 건설 클레임이 가장 빈번하지만 발생 형태가 복잡하여 분석하기가 매우 어려운 상황이다. 이러한 상황은 국제화, 개방화시대에 있어서는 해외뿐만 아니라 국내에서도 클레임에 의한 비용손실, 공기지연 등과 같은 문제점을 야기하게 될 것이다. 따라서 국제 계약실행과 국제계약에서 통용되는 조항에 대한 정확한 이해를 통하여 클레임 발생시 이에 대한 합리적 판단과 해결 방안을 모색해야 한 것이다. 본 연구의 목적은 국내 계약조건인 회계예규를 국제계약조건으로 발전시키기 위해 국제 계약조건인 FIDIC계약조건과 비교하여 그 문제점과 개선방안을 제시하는데 있다.

  • 이 연구에서는 일상적인 글자넓이를 지닌 글자로 구성된 본문에 대해 선호도를 평정하도록 하여 가독성에 관한 연구에서 밝혀진 각 요인들의 수준들 중 가장 선호되는 수준은 어떤 것인가를 알아보고, 각 요인들간 상대적 중요도를 살펴보았다. 네모 틀 글자로 구성된 본문에서 선호도를 살펴본 실험1에서는 요인들간 상대적 중요도의 순위가 글자크기, 글줄간격, 글자넓이, 글줄길이, 글자간격, 글줄맞춤, 글자모양 순 으로 나타났다. 탈 네모를 글자로 구성된 본문을 사용한 실험2에서도 가장 중요한 요인은 글자크기였으나 두 번째 요인은 글자간격으로 나타났다. 이는 글자제작원리의 차이 및 탈 네모틀 글자에 대한 비 친숙성을 반영해주는 결과이다. 글자넓이의 수준변화가 극심한 이준석과 진영선(1998)의 연구에서는‘글자넓이’가 가장 중요하게 나타난 것과는 달리, 일상적인 글자넓이를 조작한 본 연구에서는‘글자크기’가 가장 중요한 것으로 나타났으므로 교재나 책의 본문을 구성할 때 글자크기를 가장 먼저 고려하고, 네모 틀 본문의 경우에는 글줄간격, 글자넓이 등을, 탈 네모틀 본문의 경우에는 글자간격, 글줄간격 등을 고려하는 것이 바람직할 것이다.

  • We present basic data for developing new research topics and closely examine the existing data on the development and organization of the Nakdong River Estuary Delta by analyzing various studies of the area, including ocean engineering, coastal engineering, ocean environmental engineering, geomorphological, and geological studies. We first defined the general concepts related to the estuary and delta and reviewed the historical development of the Nakdong River Estuary Delta over the past 100 years. We then examined the origin and core elements of the estuary deposits that constitute the delta. In addition, we scrutinized the main factors affecting the development of the delta and analyzed existing research on delta development mechanisms by core researchers. The construction of an estuary barrage is one of the main factors effecting estuarine circulation and has altered the physical oceanic environment, area of deposition, atmospheric environment, and vegetation community of the delta. These factors affect the estuary circulation in turn, altering the delta. Along the Nakdong River, an unsteady-state sandy barrier appears at approximately three times the distance of the wavelength of incident offshore waves, and this terrain forms approximately 10-15 years after reclamation in the interdistributary upper stream and transforms the shoreline. It is necessary to develop a technique to predict terrain change that reproduces the erosion and accumulation of estuarine deposits. To determine the parameters and variables necessary to reproduce this system, continuous on-site monitoring is necessary. The existing research did not fully examine the terrain changes in Nakdong River Estuary or the periodic developmental characteristics. To understand the future process of estuary delta development, it is necessary to establish an integrated management system.

  • In addition, an intense competition depending on the diversity of consumer demands women's clothing brands show changes in market organization such as diversification of the circulation market and general market depression in this rapidly changing fashion environment. Companies tend to use fashion VMD (a marketing-strategic approach) as a differentiation method to create a fashion brand shop image as brand differentiation becomes difficult due to generalization of techniques. This study analyzes forms and types of VMD recognized by consumers within this marketing communication environment and Q methodology was adapted to analyze the subjective internal order of individuals. First, a set of stimuli that presented the brand name and another without it were prepared (two sets in total) to examine the effects in the presentation of the brand name. Stimulants with the brand name were presented to the subjects by the same method after an experiment through stimuli without the brand name presented. As a result, VMD recognition factors were classified into 4 Q factors in cases of stimuli without brand names and 2 factors in cases of stimuli with brand names. This indicates that among brand functions, the role of simplifying information management and grasping the thoughts of consumers was applied. This study has a practical value of presenting VMD directions of each brand image based on the factors discovered.

  • Although Frank Lloyd Wright represents himself as one of the greatest American master architect, the master architects contribution towards the advancement in the modern history of architecture goes beyond just creating landmark buildings. Through out his life, he was the leading architect not only in the area or architectural design but showed his talent in interior architecture, furniture, fabric, lighting fixture, art glasses, tablewares, silver wares as well as in graphic design which should cover all the elements related to the "total design" in architecture. As seen in his architectural design, the "total design" concept also reflects both beauty and logic of the nature and strengthens his theory of the organic architecture design. The research began with finding out the relationship between his architecture, nature and the supporting design elements mentioned above. the purpose of the research is to analyze the relationship of the spatial organization and the design elements in Frank Lloyd Wrights architectural works from the point of "total design" view and provide the valuable guide line for the development of the modern interior design. His design theory, based on the fundamental ideas of the nature, his organic architecture design, and reference materials to support total design concept will be discussed on chapter 2. And on chapter 3, application of the total design in his actual project will be analyzed. The data and analyzation have been completed based on written references and actual visit to the project sites. Frank Lloyd Wright placed highest value on the human beings and enjoyed presenting new ideas and forms to create better environment for the humans through his architecture and interior design projects. While he was presenting new ideas he continued to support design for democracy which has close relationship to the new frontier spirit of America. He was the master architect for the general society with accurate understanding of the life style of the public with design sensitivity shown in his concept of the total design.s concept of the total design.

  • This thesis is designed to take a close look into the characteristics of architectural space through the standard of beauty, which has been created apart from our desires at certain cultural or historical periods of time. It will try to construct the outline of conception about the beauty throughout many centuries. First of all, contents of the research will focus on the aspects, which people have been considering as beauty eversince the ancient time without having any assumptions on its concept. For example, if the beauty of art has been accepted by the theories of modern aesthetics while degrading the beauty of nature, its value could have possibly been much more appreciated. The standard of beauty has been going through the process of change in such history of mankind. The general standard of beauty, which was established in the ancient time was the proportion and harmony between many elements. Afterwards, beauty was expressed as colors and light in medieval times. Expression of beauty using ugly features such as monsters or demons also existed at the time. Beauty has been periodically developing from supernatural to gracious, rational, noble, romantic, religious, mechanical, and today's media. The concept of beauty established from the above has been appearing throughout various culture such as dress and decoration at the given period of time. It would later affect the formation of space as well as decoration for architectures and styles. It will be analyzed throughout the five design elements; style, composition, materials, components, and form. The thesis would like to find the spatial order of beauty from the result of the analysis. The analysis will examine the possibility for which the recomposition of beauty will be provided as a design process for the new era. The Greek beauty represents a shape. The shape represents proportion and the proportion represents given numbers. However, beauty is being expressed by the opposite process at the present time. In other words, computers will arrange the numbers, which would formalize the proportion between the numbers. Beauty would be presented when the shape is presented as certain forms.

  • Objective : To poll oriental medical doctors on their opinions about the necessity of standard medical charts and of detailed items in their development. Currently, oriental medical institutions use their own medical charts, but a standard medical chart is necessary for medical information sharing. Methods : Report by 912 of the 10,490 oriental medical doctors surveyed on their general aspects, actual conditions, and requirements. Results : The oriental medical doctors surveyed who worked in oriental medicine clinics, oriental medicine hospitals, and public health centers said medical examination programs should consist of chief complaints (said by 814 respondents or 89.25%), history (792 or 86.84%), ordinal symptoms (753 or 82.57%), diet (727 or 79.71%), emotions and overstrain (654 or 71.71%), side effects and allergies (622 or 68.20%), improvement of symptoms (605 or 66.34%), a questionnaire on particular diseases (558 or 61.18%), social aspects (523 or 57.35%), a physical examination (520 or 57.02%), a questionnaire on syndrome differentiation (514 or 56.36%), diagnosis using medical devices and laboratory tests (471 or 51.64%), and Sasang constitution (357 or 39.14%). Ninety-one percent of the respondents said they intended to use a standard chart, and 82.19% agreed to share patient information with medical institutions. Conclusions : Over 90 percent of the oriental medical doctors surveyed said they need a standard medical examination program. Oriental medical examination items that correspond with the opinions of the oriental medical doctors surveyed and of experts will thus be developed, and the draft chart will be distributed to oriental medical institutions with the developed medical forms and electronic medical chart.

  • In this study I purpose a new approach to the study of Korean costume history which includes a statistical method used in the prac-tical measurement of excavated Po's and the analysis of their quantitative changes. In the framework used in this study I de-pend on the nineteen variables picked out from the typological and chronological analysis of excavated clothes. The interrelationship of the variables as well as the standard of each part and its deviation in other forms are may main concern. Other methods are also very useful in my thesis: Correlation analysis Regression analysis Discrimination analysis Cluster analysis Discrimination analysis Cluster analysis Factor analysis One way analysis of variance. The findings of my study can be summarized as follows: 1. Every type of po has a general tendency to have more broadened sleeves while it does not show any considerable changes in the total length and in the width of armholes. 2. In the Correlation analysis each part of Po's is handled separately accordign to its chronology and type. The Regreesion analysis makes it possible to provide the sizes of miss-ing parts in excavated clothes and the numeri-cal value of each part needed in the pattern making. 3. The Discrimination analysis of the Po's whose types are unknown leads to the con-clusion that Chongsam and Chikryong Po are classified into Chikryong Po whereas Hongui is classified into Jooui In addition I propose discriminational function by which the age classification is possible discovering the variables associated with time change. 4. Five items-Gerneral Park's clothes Taewongun's clothes and three others produced later for the purpose of preserving Korean costume are proved to be in a differ-ent group and hence analyzed separately in the visual grouping of changui which is done after the cluster analysis and the factor analysis. 5. The results of the one way analysis of variance reveal that there is a difference in each part from period: the back width the sleeve length the sleeve width thelean fig-ure the breasttie length the breasttie width outside quesset upper inside quesset lower outside neckband length insideneckband length etc.

  • The purpose of this study is to build a database of patient information for efficient radiotherapy management. Microsoft Office Access was used to build the database owing to its convenience and compatibility. The most important aspect when building the patient database is to make the input and management of patient information efficient at every step of radiotherapy process. The information input starts from the patient's first visit to the radiation therapy department and ends upon completion of the radiotherapy. The forms for each step of radiotherapy process include the patient information form, the radiotherapy schedule form, the radiotherapy information form, the simulation order form, and the patient history form. Every form is centrically connected to the radiation oncology department's patient information form. A test revealed that the database was found to be efficient in managing patient information at each step. An important benefit of this database is improved efficiency in radiotherapy management. Information on patients who received radiotherapy is stored in a database. This means that this clinical data can be found easily and used in future, which will be helpful in research studies on the radiation oncology department. Benefits such as these will potentially contribute to improved radiotherapy quality.
