In this study, we defined abandoned vacant housing, as well as analyzed where and how the vacancies occurred. The temporal range of this study is 2005 and 2010, while the spatial range is nationwide. The minimum unit of space for the analysis is city district. First, we suggested that in the rural areas, it is necessary to manage an aged detached housing, while in the urban areas, it is necessary to manage aged apartments in order to prevent a large amount of old apartment buildings from becoming an abandoned vacant houses. Second, we proposed to select and manage the priority area in the empty area management. Finally, in the areas where other vacant houses are populated, the abandoned housing problem should be discussed with different measures from a long-term point of view in terms of population movement, population decline, and aging population.

Although people want to learn guitar easily and happily, it is difficult to learn because many restriction comes from expense, student's efficiency and teacher/s skill. In this paper, the guitar teaching program has been developed for who is difficult to learn guitar fingering. The guitar teaching system with ATmega 128 was programed using visual studio MFC program. The guitar fingering U/I program was investigated for beginners easy to learn the code and playing with guitar.

Generally, it is not easy to learn guitar fingering for beginner. In this paper, therefore, we attach LED to flat board of guitar to more easily teach the beginner and also implement LED control system that can connect ATmega 128 in order to drive LED attached to guitar. The guitar's flat board is connected with ATmega 128 as communication method of Zigbee. We also develop UI that easily can be learned code and playing for guitar, programmed by guitar fingering and perform the research for guitar fingering using LED.

본 논문에서는 기타를 배우는 초보자가 조율을 쉽게 할 수 있도록 지원하는 시스템을 구현하였다. 본 시스템은 입력된 기타음에서 A/D 변환 및 FFT를 이용하여 pitch를 추출하였다. 기타음 인식 알고리즘을 적용하여 줄감개의 조작량과 조작 방향을 '약 $45^{\circ}$정도 감아라.', '아주조금 풀어라.' 등과 같은 언어적 표현으로 나타내어 조율 할 수 있게 하였다. 기타를 처음 접해보는 피험자들에게 본 시스템을 적용시켜 본 결과 피험자들은 시스템의 언어표현과 적절한 조작 횟수에 대하여 만족감을 나타내었고 조율 결과도 숙련자의 조작과 동일한 효과를 얻을 수 있었다.

This study analyzed humanities and social science (HSS) journals of KCI to examine the multidisciplinarity and interdisciplinarity in the general and miscellaneous fields (hereinafter referred to as 'GM fields'), The multidisciplinarity and interdisciplinarity identified in this study will be a foundation to improve classification of KCI journals in GM fields. Each journal's multidisciplinarity and interdisciplinarity were measured by journal-level entropy and document-level entropy, respectively, in the citation relationships. According to the analysis, GM field journals have wide ranges of multidisciplinarity and interdisciplinarity. To improve classification quality of journals in GM fields, the general humanities should be considered as a new classification class for the multidisciplinary and interdisciplinary journals in the humanities. Furthermore, this study proposes a strategy to reclassify GM field journals of HSS according to their multidisciplinarity and interdisciplinarity.

오랫동안 젊은이들의 각광을 받고 있는 전기 기타는 모양은 조금 바뀌었지만 픽업에서 얻은 음성 전류를 유선으로 증폭기로 보내는 방법을 그대로 사용하고 있다. 한편 연주자가 넓은 무대에 설 때는 증폭기 바로 앞에 서야하기 때문에 움직임에 제약이 있다. 이를 극복하기 위하여 기타에 송신기를 장착하고 앰프에 수신장치를 설치하여 연주자가 자유롭게 움직이며 연주할 수 있는 방안을 제기한다.

Characteristics of a guitar sound changes according to the internal structure a guitar. The developed system uses a PC to analyze a guitar sound, which will have different characteristics in accordance with the internal structure of the guitar and the material that the guitar made, and make a data base. The developed system consist of three parts; a mechanical body which holds a guitar and the internal structure of the guitar can be changed easily; DSP sound acquisition boards which have multi channel sound input and A/D converting abilities with RS232C data transfer to PC abilities; and software which runs on a PC to analyze the input sound and make a data base.

This paper aims at solving the bending problem by the applied force due to the configuration of the neck part of guitar. At reinforcing and using the existing guitar, the method to understand the area vulnerable to the load was studied. In this study, the material property of wood applied to the practical guitar was applied and the finite element analysis was carried out after the modelling. By using the result through the study of this paper, it is thought that the foundation of material about bending and damage which has been recognized as the problem of existed guitar can be obtained. This study aims at improving the guitar as the design to reinforce it is studied. The bending and the damage are prevented and the durability can be improved by applying to the practical design on the basis of the result of the improved study model. And it is possible to be grafted onto the convergence technique at design and show the esthetic sense.

This study was performed for 182 rural persons of patients who had admitted at National Masan Tuberculosis Hospital from 21th Feb to 18th Aug, 1994. We investigated diseased history based on the data according to the kind of occupation. The results were summarized as follows : The most common occupation was no occupation(35.2%). The most common age group was 5th decade(25.3%). By the age, the most common group in cases of no occupation was over 7th decade and under 5th decade, and agriculture was over 7th decade and 6th decade. Male(83.5%) were more than female, but wasn't significantly different. The most common group in the level of education was over the graduate of high school. The group that have ever drunken(p<0.05) and smoked(p<0.01) was significantly different in labour, service, agriculture, others. Family history, combined disease, symptom were no significantly different by occupation. Both lung fields on the chest X-ray was the most common site of invasion(82.4%). In the tests of AFB smear and culture, the differences according to the occupation were not. At the time of admission, the most common group in the state of treatment was initial treatment. The multi-drug resistance tuberculosis was no significantly different by occupation.
