Purpose: The purpose of this study was to investigate the denture attachment status and the denture need of elderly Koreans and to provide basic data for improving the quality of life by developing methods and education programs for the oral health of the elderly. Methods: This study selected 4,340 persons who completed questionnaires and oral examinations among elderly people aged 65 or older only from the National Health and Nutrition Examination Survey data of the 6th period (2013-2015). Results: There was a significant relationship between age, residence, and education level in complete dentures. There was a significant relationship between gender, age, residence, and education level in the partial denture wearing state. In the complete denture need, there was a significant relationship with age. The need for partial denture was found to be significant in gender, age, and residence. Conclusion : Based on the results of this study, it can be used as basic data for oral health education and dental prosthesis related to denture which can improve oral health of the elderly in the future.

The old house at No'eun-ri, located in Hongseong-gun Hongbuk-myeon of the Chungcheong Nam-do province, really seems like the old house of late Seong Sam-mun who died in 1456. The original structure of the house seems to have been symmetrical, in terms of its left and right sides, and the females' chamber(Anchae) as well as the guest quarters(Haeng'rang-chae) would have featured a Matbae(맞배) fashion. The flank chamber and corridor would have displayed a multi-storied shape, and people would have been able to traverse the inside of the house all the way to the second story of the residence. We can see such shapes and dispositions from other 'ㅁ'-shaped houses - found in Chungnam and Gyeongbuk regions - which are now considered as distinct characteristics of certain residences constructed before the war with the Japanese in the 1590s, confirmed from extant vestiges and historical records of that time period. It can be concluded that the old house at No'eun-ri does harbor the traits and elements that resembled the upper class residences of the Joseon dynasty's early half period.

최근 도심 발파작업이 증가함에 따라 발파진동 및 소음에 대한 주변 민원문제가 증가되고 있으며, 이에 굴착 시공성 저하로 인하여 시공사와 민원간의 분쟁이 지속적으로 증가하고 있는 실정이다. 본 사례는 전자뇌관에 의한 분산장약 발파공법을 적용하여, 발파진동 및 소음에 대한 제어뿐만 아니라 공사기간을 단축시킴으로서 발파에 대한 민원간의 분쟁을 최소화하였다. 도심 구조물 근접구간의 발파공사에서 발파진동 및 소음을 허용기준 이하로 제어하면서 굴착 시공성을 높일 수 있는 굴착방법으로 널리 활용될 것으로 예상된다.

Evaluation model for damage consciousness was established through the survey of 2,210 residents' consciousness on aircraft noise near Taegu Airport. There were none who replied that the level of the aircraft noise was as los as it was quiet. 77(3.5%) people replied the noise was normal, and 2,133(95.5%) people said it was noisy. As to the period of time when the aircraft noise occurred, 51%, 97%, 86%, 0.6% of the residents pointed out the morning time, the day time, the evening time, and the night time, respectively. Because of aircraft noise, 73%, 88%, 70%, 77%, 78%, and 33% of the residents felt it disturbing indoor conversation, telephoning, watching TV or listening to the ratio, reading or meditating, working, sleeping, and studying, respectively. It was examined that the bad effects of aircraft noise on the health were severe : 43% of the resident said they experienced embarrassment. 52% astonishment, 66% absence of mind, 61% heart-beating. 77% headaches, 78% earache, and 93% displeasure. For the survey of the residents' damage consciousness about aircraft noise, the level of aircraft noise was set as an objective variable, and gender, age, occupation. Education, the type of house, the structure of windows, the consciousness of settlement in the district, and the period of residence were set as explanatory variables. And the quantification theory I was applied to the analysis. The most influencing factor of the damage consciousness on aircraft noise was the education, the second occupation, the third age, the forth the consciousness of settlement, the fifth the period of residence, the sixth gender, the seventh the type of house, and the least influencing factor among them was the structure of windows. These findings will be a useful guideline when the government seeks to set up policies which will help solve the resident's noise problems near Taegu Airport.

The goal of this research is to compare influences for living periods between physical functional satisfaction and psychological emotional satisfaction in a ghetto area. The research site is 'Sujin1 dong' in Sungnam city which is one of the oldest residential areas in the city. Based on the analysis of the urban contexts for the research site, surveys are conducted to gather the data which are treated by several statistical techniques: 'Factor analysis', 'Reliability Analysis', 'Multiple regression analysis'. Through the statistical process, conclusions are drawn as follows. In the ghetto urban area, (1)-The higher the psychological emotional satisfaction, the longer the living period, (2)-The longer the residence period, the lower the physical and functional satisfaction, (3)-The two satisfactions tend to be opposite to each other according to the living period. (4)-The psychological emotional satisfaction is more related with living period than the physical and functional satisfaction is.

Many uncertainties are found in the evaluation of historical eatrhquake records. The seismic response characteristics of a three-bay-straw-roof house which is a typical from of residence in ancient period is quantitatively estimated. Two 1:4 scaled models are used in the test Real earthquake time histories for rock and competent soil conditions are used.

We consider an M/G/1 queueing system with multiple priority classes of jobs. Considered preemptive rules are the preemptive-resume preemptive-repeat-identical, and preemptive-repeat-different policies. These three preemptive rules will be analyzed in parallel. The key idea of analysis is based on the consideration of a busy period as composite of delay cycle. As results we present the exact Laplace-Stieltjecs(L.S) transforms of residence time and completion time in the system.

하계 남강댐 방류수 유입에 의해 강하게 성층화된 남해 강진만에서 3차원 수치모델과 결합된 라그랑지안 입자추적모델링 실험을 통해 방류수의 거동 특성과 만내 평균 체류시간을 추정했다. 조위와 유속장, 수온장, 염분장에 대해 각각 스킬 분석(skill analysis)을 이용해 검증했고, 그 결과 대부분 85%가 넘는 재현율을 보였다. 방류 초기 투하한 입자는 노량수도와 대방수도를 통해 외해로 유출되었으나, 최대 방류시기에 투하한 입자는 남향하는 강한 밀도류에 의해 사천만, 진주만, 강진만으로 유입되었으며, 지형적 요인과 해수유동 특성상 외해로 유출되지 못하여 체류시간이 증가했다. 투하한 입자 전체의 평균 체류시간은 약 65.9 시간(약 2.75일)이며, 초기 방류시 투하한 입자의 평균 체류시간은 약 55~65 시간, 방류 종료시 투하한 입자는 약 60~70 시간이다. 방류량 최대시 투하한 입자는 약 70~80 시간으로 방류량이 증가하면서 체류시간이 약 10~20 시간 증가하는 양의 상관성(R = 0.81)으로 나타났고, 이는 강진만 생태계가 장기간 지속적으로 저염수에 의한 염분 충격을 받은 것으로 볼 수 있다.
