The first priority we face in the conservation of wall paintings, is the conservation of painting layer. The 'painting layer' is sometimes called the pigment layer, and refers to the painted surface. For the consolidation of this painting layer we use 'fixative'. Fixative is a common adhesive which has been used in various field and conservators have made up for the weak points in the consolidation of wall paintings. In my thesis, I will summarise the range of use, standards of selection, and results of research on the use of fixative in the conservation of European paintings. In addition, I will describe various kinds of our traditional fixatives. As synthetic resins have proved that it is not ideal as a fixative for wall painting, conservators have studied to find an alternative. Same as European conservators, Asian scientists has researched to find alternative fixative which is more suitable to the wall paintings in Asia based on their traditional techniques and materials. Therefore, 1 have studied to find an adequate fixative for our own wall paintings and I could conclude that we can consider traditional fixative which is made of 'seaweeds' as an alternative and it is very important to proceed research and experiment on this material. 벽화 보존처리에서 우선 시 되는 부분은 채색층에 대한 보존처리이다. 채색층이란 그림이 그려진 표면층을 말하며 안료층이라고도 한다. 이러한 채색 층의 보존을 위하여 인위적으로 고착제(固着劑, Fixative)를 사용한다. 고착제란 우리가 일반적으로 알고 있는 접착제를 말하며 그 사용범위는 방대하다. 그 중에서 일부를 보완하여 벽화문화재 현장에서 적용하므로 그 목적성과 사용범위에 의해 고착제라 지칭하는 것이다. 이번 조사를 통하여 그간 유럽에서 사용된 벽화의 이상적인 고착제을 위한 연구성과에서 사용범위, 선택기준, 연구결과 등을 요약 기술하고 우리의 전통적인 접착제를 정리하였다. 현재 합성 수지를 이용한 고착제의 문제점이 과거 처리된 벽화 문화재에서 발생되고 이를 위한 대안을 찾기 위한 노력이 진행 중이다. 특히 동양 벽화의 경우, 전통적인 방법을 통한 해결책을 제시하고 연구 중이다. 우리의 전통 접착제 중, 도박과 같은 해초풀의 활용을 통한 보존처리 현장의 적용이 가능할 것이며, 이를 위한 구체적인 실험과 연구가 절실함을 알 수 있었다.

금산사미륵전벽화는 사찰벽화에서 나타나는 손상상태 중에서도 극히 심각한 상태에 놓여있다. 이들 벽화에 대한 보존처리에 앞서 벽화의 구조, 특성, 손상유형 및 원인 등 거시적 관점에서 사전조사를 하고 그 결과에 대한 평가를 실시하였다. 손상이 가장 심한 곳은 건물의 남측으로, 채색층과 마감층의 손상이 두드러지는 것으로 조사되었다. 채색층과 마감층 일부가 도막을 형성하며 얇은 두께로 벽체로부터 박리 박락되었으며, 상태가 심한 경우는 마감층 전체가 이탈되기도 하였다. 주요 손상원인은 건물 하중으로 인한 벽체의 균열 및 파손과 과거 보존처리에 사용된 보강재의 열화로 판단된다. 채색층 및 마감층의 손상은 환경적인 요소에서 기인하는 온습도 편차, 자외선으로 인한 물리화학적 손상과 과거 적용된 합성수지 고분자물질의 기계적 물성저하로 인한 영향 등이 상호 복합적으로 작용하여 발생한 것으로 보인다. 벽체의 균열, 박락과 과거 보강부위 이탈 등의 손상은 사찰벽화와 물성이 다른 보강재료의 사용과 유럽식 이전복원 공법의 무리한 적용에서 비롯되었다고 판단된다. Since wall paintings in Maitreya Hall of Geumsan-sa temple had displayed a serious state of damage and deterioration, a detailed examination such as structural analysis of the wall, cause of damage, and the state of deterioration have been thoroughly conducted before the conservation treatment has commenced. The most seriously deteriorated part of the wall paintings was the south wall of the building in particular in its painted and surface layer. The painted layer had formed its own layer of thick, which has been separation from the surface layer. As such problem developed the whole surface layer has been separated from the wall. The problem has been caused by two reasons: 1. the heavy weight of the roof section and it caused cracks and damage on the wall; 2. the loss of function of consolidating material and it caused discolouring and the separation of surface layer from the wall. The cause of damage on the painted and surface layers can be assumed in two ways: 1. its surrounding environment such as the change of temperature and humidity level and ultraviolet rays ; 2. the loss of mechanical function of consolidating material, synthetic resin which had been applied in the past conservation treatment. The separation of layers from the wall and cracks was caused by the mistake in choosing an applicable consolidating material and dismantling technique which had ignored a different characteristic of the wall painting of Korean buddhist temples.

This research was based on using status and factors associated in public health centers survey in 703 local residents from September 1 to 25, 2015. Data were analyzed with chi-square test, t-test, one way ANOVA, and Stepwise Multiple Regression analysis using SPSS WIN 21.0 program and significance level was set at p<0.05. It was investigated that Incheon city health centers` utilization of residents were 38.8%, the annual average of utilization was 3.92 times. Health centers were mainly used by themselves (25.3%) or recommendation of the people around them (17.8%). The reason why they don`t use was no need (27.0%) and don`t know well (9.4%) or long distance (7.8%). The average of awareness about the total health programs was 41.2%, the average of utilization rate was 8.1%, both higher rate of awareness and utilization about health programs were vaccination (86.6%, 36.9%), and health examinations (67.2%, 18.7%). The average of satisfaction about health programs was 3.88 out of 5, sealant (4.26 points) and rationing fluoride solution (4.07 points) indicated a high level of satisfaction. The most common factor which represents the impact on public health use and use frequency were the time it takes to move, also gender, age and form of home ownership were major factor in common. Based on this, we have to seek concrete measures of national health programs which conducted to improve the health of local residents can be implemented successfully.

To compare the stationary dental X-ray generator and the portable dental X-ray generator and to understand spatial radiation dose depended on locations by measuring spatial radiation dose of the portable dental X-ray generator. The researchers used an Ionization chamber to measure spatial radiation dose which was generated while applying X-ray radiation to real bone skull phantom with both portable and stationary dental X-ray generator. There were 4 measurement locations which were immediate anterior, right, left and posterior. Distance of measurement was 50 cm in every location and the recorded result is an average of two applications of X-ray radiation to the maxillary molar area under the condition of 70 kVp, 3 mA, 0.1 sec. Average spatial radiation dose of portable X-ray generator was 37.51 μSv, much higher than that of stationary X-ray generator which was 10.77 μSv (p<0.001). The result of the spatial radiation dose of the portable X-ray generator showed a huge difference depending on types of units which varied from 17.77 μSv to 68.90 μSv (p<0.05), also depending on the measurement location, immediate anterior resulted in the highest radiation dose of 54.14 μSv and immediate right was the lowest of 13.60 μSv. Immediate left and posterior, however, resulted in similar radiation dose which were 42.12 μSv, 40.18 μSv (p<0.01). With this result, we claim that usage of portable dental X-ray generator should be restricted to patients who can`t move and exposure to radiation should be minimized by wearing lead-apron.

To examine the relationship between occurrence of oral malodor and smoking, drinking, oral health behavior characteristics. A total of 144 adults were measuring the malodor by use of Oral Chroma volatile sulfur compounds. Data were analyzed with t-test, one-way of variance and multiple regression analysis using SPSS 12.0. hydrogen sulfide(H2S) was indicated to be so higher concentration in the group of carrying out scaling sometimes than the regularly group(p<0.01). methyl mercaptan(CH2 SH) was indicated to be higher concentration in previous smoker than non-smoker and smoker(p<0.05), smoking for over 20 years was higher than the under 20 years group(p<0.05). The group of drinking over 5 times a week was indicated to have higher concentration than the under once-twice a week group(p<0.01). The group of not toothbrushing before going to sleep had higher concentration than the group of toothbrushing before going to sleep(p<0.05). The group of scaling sometimes was indicated to have higher concentration than the group of scaling regularly(p<0.05). dimethyl sulfide((CH3)2 S) was indicated to be higher concentration in the group with over 2 bottles of Soju than in the group with under 1 bottles of Soju(p<0.01). The regular scaling will need to be carried out in the preventive dimension for managing oral malodor. The guidance on non-smoking and moderation in drink will need to be surely included.
