The purpose of this study is to investigate attitude factor related to hearing conservation and to find attitude affecting the preventive behavior for hearing conservation. The research method used in this study was self-administered questionnaire. Samples of the study were composed of 353 workers exposed noise selected randomly in 10 ship-building manufacturing companies. Authors extracted following 9 factors related hearing conservation from 26 attitude propositions prepared from previous study results and health belief model; (1) general perceived susceptibility, (2) relative perceived susceptibility compared with colleagues, (3) concern to the personal protective devices, (4) perceived severity and concern to the hearing capacity, (5) concern to the hearing and noise assessment, (6) concern to the control noise and hearing conservation, (7) group pressure and reason of wearing protective devices, (8) apathy of hearing loss from noise, (9) knowledge about hearing conservation. Attitude factors affecting the preventive health behavior were general perceived susceptibility, concern to the noise control and hearing conservation, and concern to the personal protective devices in the case of wearing personal protective devices. But in the case of avoiding noise exposure as preventive health behavior, perceived severity and concern to the hearing capacity was a significant attitude factor with knowledge about hearing conservation.

This study was performed to assist the employer to establish the effective program for hearing conservation of noisy industry. The study subjects were health care managers of an industry and the study industries were devided into two groups(Group I, 37 industries; have the workers diagnosed as noise-induced hearing loss, Group II, 41 industries; not have the workers diagnosed as noise-induced hearing loss) and the question method carried out through the face to face interview. The contents of questionnaire for OSHA's hearing conservation program(HCP) consisted of seven components: 5 questions of monitoring of employee noise exposures(component 1), 6 questions of the institution of engineering, work practice, and administrative controls for excessive noise(component 2), 8 questions of the provision of each overexposed employee with an individually fitted hearing protector with an adequate noise reduction rating(component 3), 14 questions of employee training and education regarding noise hazards and protection measures(component 4), 9 questions of baseline and annual audiometry(component 5), 3 questions of procedures for preventing further occupational hearning loss by an employee whenever such an event has been identified(component 6), and 1 question of recording keeping(component 7), thus total numbers of questions was 46. The numbers of statistially significant difference(p<0.05) between two groups were 2(25.0%) among 8 questions of component 3, 10(71.4%) among 14 questions of component 4, 3(33.3%) among 8 questions of component 5, 2(6.7%) among 3 questions of component 6, and 17(37.0%) among total 46 questions of questionnaire. Above results showed that the level of HCP acceptance in group I was lower than in group II. Thus employer's understanding about HCP should be precede for the effective hearing conservation program of employee and the adequate hearing protector, training and education, baseline and annual audiometry, and procedures for preventing further occupational hearning loss for hearing conservation would be more emphasized.

A paulownia wood has been widely used with various advantages as its low weight, permeability, convenient workability and aesthetic patterns for a long time. However, the related empirical researches and simultaneous evaluations of functionality are insufficient compared with acid-free archival boxes for now. In this study, the indoor and outdoor temperature and relative humidity control and heat release rate were evaluated under the controlled and uncontrolled circumstance in 2018. The paulownia wood storage box showed superior control effect of relative humidity than the acid-free archival box in constantly uncontrolled environment. Also, the possibility of the flame diffusion from the surface of the materials was higher for the paulownia materials, and the acid-free archival box showed more dangerous patterns in the early stages of the fire.

Preventive conservation is one of most important issues in the field of conservation for paper-records. Many researchers have been studied environmental factors such as effects of humidity, temperature, biological attack and air pollutants. Air pollutants strongly associated with oxidative and hydrolytic degradation of cellulose. It is important to control air pollutants in storage environment to improve stabilities of conservation environment. Four paper samples have been analyzed for their accelerated aging characteristics by air pollutants, sulfur dioxide, nitrogen dioxide, ozone, carbon monoxide. Physical and optical properties and weight molar masses(Mw) showed that interactions between air pollutants and paper sample. Nitrogen dioxide, ozone caused severe damage to cellulose in paper by hydrolytic and oxidative decompositions during aging.

In the study, we confirmed morphological traits and calculated the Risk Class of 25 mould species, including Tyromyces palustris, through decomposition rate of substrate for characteristic confirmation of injured microorganisms. We received the injured microorganisms in wood and it was pure cultivated. We observed growth traits and decomposition rate of substrate. Also, it allows the calculation of Risk Class to be worried in the case of growth in wooden cultural properties. As a result, Tyromyces palustris, representative of brown-rot, has the characteristics about decomposition rate of substrate - Cellulose ; more active(+++), Lignin ; more active(+++), Xylan ; more active(+++), Starch ; active(++). We classified Tyromcyes palustris as a first Risk Class and as a second Risk Class about Schizophyllum commune et al(9 species, See table 1. We look forward to offering standard data base for evaluating Risk Class as a matter of applying preventive conservation in wooden cultural properties through our study.

벽화나 건물벽에 장식한 부조작품들은 건축물의 일부라는 특성을 가지고 있다. 따라서 여타 예술 작품과는 달리 현재의 위치에서 보존관리를 하는 것이 가장 합당한 방법일 것이다. 그러나 이들 작품의 보존을 위해 적절한 보존환경이 제공되는 곳으로 이전을 해야 하는 불가피한 경우가 발생하게 된다. 따라서 이러한 작품들을 이전해야 할 경우 충격이나 진동이 불가피하고 이들의 재질이 일반적으로 부서지기 쉽다는 것을 고려하여 작업 중 훼손을 방지하는 조치에 더 많은 주의를 기울여야 한다. 본 고에서는 주택 재개발 사업에 따라 철거위기에 놓여 있는 권진규 '부조'를 대상으로 부조작품의 이전에 대해 언급할 것이다. 특히 훼손 방지차원의 보호조치와 포장방법을 중심으로 한 이전 전과정과 복원작업을 소개하였다.
