According to the survey for working environment of the cashiers in highway tollbooths, workers replied that noise was the most harmful substances next to air pollutant in the tollbooth. Researches on the noise levels exposed to cashiers in the highway tollbooth scarcely have been performed. Therefore, the aim of this study was to acquire baseline data to prevent health impairments of the cashiers by evaluating noise level exposed to them. Noise dosimeters were used for monitoring workers' noise exposure level in the tollbooths at 8 different highway tollgates. The noise levels of tollbooths did not exceed noise exposure limit of the ministry of labor, 90 dB(A). The average TWA inside of the tollbooths was 55.4 dB(A) and the average TWA outside of tollbooths was 58.3 dB(A). The average TWA outside of tollbooths was slightly higher than that of inside of tollbooths. However, the significance probability(p-value) was 0.255 which means statistically not significant. The noise levels inside and outside of tollbooth were statistically significant to both mean traffic volume per day and traffic volume of passenger car.

This study was performed to figure out the recognition on forest certification by consumption propensity and socio-economic characteristics of wood cabinet consumers. The mean score of recognition on SFM and FSC showed comparatively low, 2.25 and 2.20(5-point likert scale), from the analysis result on 88 valid questionnaires of 90. The respondents rate of eco and non eco-friendly group formed 80.7% and 18.2%, there is a significant gap between two groups on total questionnaires. The percentage of respondents recognizing on SFM and FSC was about 31% (eco-friendly), 5.6%(non eco-friendly, SFM) and 2.8%(non eco-friendly, FSC) within each group. It showed that the socio-economic characteristics on eco-friendly respondents were higher than the others about more 1.3 times in the married rate, average age and monthly householding income.

최근 고속도로의 길이와 운전 차량 수가 빠른 속도로 증가하고 있어 운전자들에게 고속도로 교통상황를 신속하고 정확하게 제공하는 것이 중요한 문제로 대두되고 있다. 고속도로통행료수납시스템(TCS: Toll Collection Systrem)은 전국 고속도로를 주행하는 차량의 통행 정보를 실시간으로 제공하므로 교통 상황 예측에 유용하게 활용될 수 있다. TCS 자료는 차량이 입구영업소를 통과한 후 출구영업소를 통과하는 데 소요된 시간으로서, 운전한 시간, 휴게소 체류시간 등을 모두 포함한 통행시간으로 운전자의 운전 특성, 통행 목적, 피로의 정도에 따라 편차가 크게 나타난다. TCS 자료의 통행시간을 기초로 예측된 정보는 이러한 불확실성을 포함하고 있기 때문에 이를 활용하기 다양한 데이터처리 기법이 필요하다. 본 논문에서는 TCS 자료의 효율적인 전처리 및 교통 예측 기법 현황에 대하여 기술하고 향후 발전 방향을 제시하였다.

The purpose of this study was to investigate the furniture use pattern and needs for built-in furniture of apartment residents. The subjects were 289 housewives who live in apartment houses in Haeundae, Busan. The size of apartments was 60 $m^2$ or 85 $m^2$.The self-administered questionnaire was used. There was no any furniture pattern which can be categorized as the specific one. That is, each family has different kinds of furniture pattern in living room and master bedroom. Also, some subjects wanted to have builted-in furniture in master bedroom.

본 연구는 병원을 이용하는 외래환자들의 불만족요인과 만족요인들을 조사하여 보다 높은 고객만족 경영을 위한 기초자료를 제시하고자 하였다. 연구대상은 대전에 소재하는 일개의 종합병원 외래환자를 대상으로 2011년 10월 24일 1일간 설문조사를 실시하였다. 자료 수집은 총 160부의 설문지를 배포하여 144부를 통계분석자료로 이용하였다. 연구결과 행정지원부문의 특성 중 전반적 만족도와 타인추천 의향에 대하여 가장 많은 영향을 미치는 요인은 접수 수납 절차의 신속 간편성인 편리성으로 나타났으며 검사실 외래 진료대기실의 쾌적성도 공통으로 영향을 주는 것으로 나타났다. 이상과 같은 결과 고객을 만족시킬 수 있는 고객지향적 병원경영시스템을 구축 운영한다면 병원의 경쟁력은 향상되고 병원의 지속가능성은 높아질 것이며 고객만족경영이라는 경영목표도 달성될 수 있을 것이라 사료된다.

Despite the high historical and topological values, closed schools are rarely reutilized. The reason can be likely explained by integrity of the building structure and unawareness of the operation and maintenance for closed schools. The purpose of this study is finding a possibility of reusing closed schools by deploying SI (Skeleton and Infill) theory. SI theory is separating the "skeleton" like structure from "infill" such as interior furnishings to extend building life without complete demolishing of the building. It will allow satisfying various local community demands by alternating infill without demolishing of historical and topological value of the building. The experimental test was undertaken with closed school for this study. The local community's demands or opinions were reflected to develop a strategy for deploying infill system especially movable storage furniture to closed school. The study finds possibilities that SI theory can assist local community to 1) construct potential demand for utilizing closed school and 2) suggest strategy for operating and maintaining closed school.

Skeleton/Infill Housing in Japan was developed in 1979 in order to provide a solution to the modem problem of the need to flexibly respond to diversified demands for housing, and to establish a social basis of housing as public housing complexes are realized. In this system, the "skeleton" like building structure, which has a social nature, is separated from "infill" such as interior furnishings, which have more individuality, The public body was the unified supplier of the skeleton, and the private sector satisfied each household's needs in tenus of infill using a demander participation approach, Today however, Skeleton/Infill Housing is required to solve an entirely new housing problem, necessitating a dramatic change of infill. For this reason, this study aims to clear the infill within the system and propose a more flexible system which can provide appropriate information to improve the infill.

Dental care is becoming more available on the NHI(National Health Insurance) in Korea. Especially, complete denture, partial denture, dental scaling, and dental implant has been applied by NHI from 2012 to 2014. Although, the entire nation is not eligible for the benefit now, the more dental coverage of NHI is extended, the more regulaition is tightened. Essential documents for proof of correctness of dental treatment covered by NHI are dental records and the receipt book. Summary of regal regulation about them is as follows 1. Chief complaints of patients, diagnosis, progress, and act of treatment, drugs and materials of treatment, doctor's sign, date and hour should be placed accurately on dental record 2. Dental clinic should collect patients sharing of the dental cost covered by NHI. 3. Dental clinic should keep the receipt as proof of purchase of dental drugs or materials.

Space given at home, furniture is an important condition to determine its size. As a method for satisfying outer and functional human needs, ever changing, shaped form has also been developed. Modern people tend to decorate the beautiful living space to the needs of the beauty and space of living. In order to satisfy these requirements, the development of furniture to suit the taste of modern people is required. In this study, we add together the design and contemporary design of traditional Korean and use of raw wood can feel the natural and applied to furniture retro design. It is possible to have a motif characteristic of Hanok traditional to suggest a design where you can feel the sensitivity with retro in the direction of the current design change is large and diverse, and in harmony with the living space of modern it is an object that you study the production lighting and storage furniture with the complexity of the traditional and modern.
