The study was conducted from May to September in 1994 to investigate applicability of the Hearing Handicap Inventory for the Elderly-Screening version(HHIE-S) in parallel with the pure-tone audiometer to the initial screening test of noise-induced hearing loss(NIHL) in some noise-exposed workers. Subjects were selected by systemic sampling that took every 10th person from 6, 700 workers taking the annual occupational health examination by the department of Health Maintenance of Dongsan Hospital Keimyung University in Taegu. The authors administered the pure-tone audiometric test and self-reported questionnaire of HHIE-S including items of sociodemographic and job-related variables concurrently. The final subjects analysed were 1,019(488 males and 531 females) excluding fourteen persons who had many missing values in their questionnaires. The reliability coefficients of HHIE-S scale by Cronbach's alpha were 0.84. In the univariate analysis of hearing handicap measured by the HHIE-S, work duration, military service and the hearing threshold loss at 1KHz and 4KHz by the initial audiometer were significant in males while age, work duration and hearing threshold loss at 1KHz and 4KHz were significant in females. In the stepwise linear regression analysis, hearing threshold loss at 1KHz and 4KHz, was the only selected variable explaining the hearing handicap in males and hearing threshold loss at 1KHz and 4KHz, age, and work duration were selected in females. In ROC curves for HHIE-S scores against NIHL as gold standard which was defined by the follow-up audiogram as more than 30dB of the average of 0.5/1/2KHz and 50dB at 4KHz, the optimal cutoff for the parallel HHIE-S appeared to be 8. The results suggest that HHIE-S appeared to have some reliability and validity in this data and might be used in screening NIHL in parallel with pure-tone audiometer in noise-exposed workers.

This study was conducted for investigating the status of management of preemployment health examination and to have an effect on the worker's employment. Health managers of 103 companies in Incheon metropolitan city and Gyeonggi were interviewed by telephone. Of 103 companies, 67(65.1%) said they don't hire the applicants who have an active pulmonary tuberculosis, 80(77.7%) companies said they health HBV carrier is acceptable but active HBV carrier is not 29(28.2%) companies said they don't hire the applicants who have a hypertension or diabetes mellitus, 42(40.8%) companies said they don't hire the applicants who have a hearing disturbance. If HIVD is suspicious in X-ray lumbar-sacral region, 37(78.7% of 47 companies) said they do not hire the applicants. 29(35% of 83 companies) said they cancel the employment of the applicants who are suspicious of noise induced hearing loss on preplacement health examination. From our survey, preemployment health examination was utilizing mainly as a tool for the selection of health employees who don't have a disease. Furthermore, in many companies, additional test items are being included and getting more strict the selection criteria for preemployment health examination. For the right use of preemployment health examination, author suggested that further studies were needed to select the adequate test items and establish the reasonable criteria for preemployment health examination.

This study evaluated the actual status of special needs of the hearing-impaired person for disaster response. The analysis revealed a significant level of unmet needs in disaster response for hearing-impaired person. The 5 special needs in disaster response include: 1) communication needs, which involve securing the means to make an emergency rescue request and communicating information during the rescue process; 2) transportation needs, which indicate the effective evacuation capacity and the level of training; 3) medical needs, which address the degree of preparedness for physical and mental emergency measures and the delivery of health information for rescue and first aid process; 4) maintaining functional independence needs, which refer to the level of self-preparedness to minimize damage in disaster situations, and; 5) supervision needs, which correspond to a personalized support system provided to disaster-vulnerable groups.

The purpose of this study was to examine the effects of the activity constraints due to disability on subjective health status and daily life satisfaction among disabled, and mediating effects of subjective health status on the relationship between activity constraints due to disability and daily life satisfaction. For this purpose, the response data of 3,809 people who participated in the 5th year of the 2nd Wave of the Panel Survey of Employment for the Disabled (PSED) were used and analyzed. As a result, all sub-factors except for the degree of difficulties in hearing even when using hearing aids among activity constraints due to disability has a statistically significant negative effect on subjective health status, and all sub-factors has a significant negative effect on daily life satisfaction. And, subjective health status has a significant partial mediating effect on the relationship between all sub-factors except for the degree of difficulties in hearing even when using hearing aids among activity constraints due to disability and daily life satisfaction. Therefore, the level of activity constraint for the disabled should be reduced by providing systematic and differentiated customized rehabilitation programs that take into account the disability characteristics of the disabled, thereby improving the health level and social independence ability of the disabled. Furthermore, in order to improve the daily life satisfaction of the disabled, it is necessary to provide policy support such as the establishment of a community-based integrated support system for the disabled by linked rehabilitation program and health promotion program.

Reports on a potential relationship between sensory neural hearing loss(SNHL) and cardiovascular or hematologic factor show that the results are controversial. A detailed analysis of risk factors in the development of SNHL was carried out in 3,050 non-noise exposed healthy worker. The mean hearing threshold of both ears at 500, 1000, 2000, 4000, 8000Hz was measured and the effect of age, possible cardiovascular risk factor and hematologic factor (blood viscosity and hemostatic factors) on SNHL were evaluated. first, each of these were associated with loss of hearing sensitivity when univariately and multivariatively analysed. In a multiple regression model, age, sex, body mass index, WBC and total cholesterol level were independently associated with the mean of hearing sensitivity decrease at 4000 and 8000Hz. Second, study subjects were divided into two group (normal vs SNHL) and we compare the possible risk between both groups, and analysed univariate and multivariative logistic model. In a multiple logistic regression model, age, sex, body mass index, WBC and total cholesterol level, total protein, platelet were independently associated with SNHL. Our results show that we have some reliable indices of susceptibility to SNHL using cardiovascular measures or biochemical factor, but future, more extensive studies are required.

This is cross-sectional study to evaluate a potential relationship between air conduction hearing threshold and blood viscosity in normal adult males(n=1677). We measured hearing threshold in frequency level at 500, 1000, 2000, 4000Hz by pure-tone audiometry and RBC profiles containing red cell number, hemoglobin, hematocrit. Blood viscosity are replaced by hematocrit that are one major factor of influencing blood viscosity. PTAs(pure-tone averages) are measured by hearing threshold averages level at 500Hz, 1000Hz, 2000Hz. Grades of PTAs(pure-tone averages) are divided three groups that are less then 10.0dB group, between 10.0-19.9dB group and excess 20.0dB. The results shows significant association among hematocrit, red cell number and hearing loss(age adjust by ANACOVA).

This thesis is intended for addressing issues of the local expropriation committee system by drawing the policy suggestion through theoretical considerations on the land expropriation system of the UK and of the US, and for finding a plan to improve the system by focusing on the examples of land expropriation of local governments. The US' Takings utilize a public hearing and the jury system. When property is expropriated through eminent domain, stakeholders and citizens share the necessity of the expropriation and its awareness through a public hearing, and project institutes (administrative organizations) file a lawsuit to a law court to exercise takings. In the case of Compulsory Purchase in the UK, the system should be based on laws established by the Parliament, and the resolution to use CPO is also decided by district councils. So the system is able to prevent power abuse. As a plan to improve the land expropriation committee of local governments, it is necessary ${\triangle}$ to enhance the professionality of the local land expropriation committee, ${\triangle}$ to expropriate lands by the analysis of land type, and ${\triangle}$ to come up with alternative measures to prevent the rights of the expropriated.

Mitochondrial DNA mutations have been reported in recent years in association with sensorineural hering loss. The purpose of this study is to identify the association between the noise-induced sensorineural hearing loss and the A to G mutation at nucleotide 3243, 1555, 7445 of mitochondrial DNA. Study subjects were established by history and chart review, and audiological and clinical data were obtained. Blood was sampled from 214 normal controls, 102 noise-induced hearing loss, and 28 sensorineural hearing loss. The DNA of these individuals were extracted, and mitochondrial DNA fragments were analyzed by polymerase chain reaction. Subsequently, the coding sequence of mitochondrial DNA 3243, 1555, 7445 were sequenced, and compared to the normal sequence, and all sequence variations were analyzed by restriction enzymes. Mitochondrial DNA mutations $(3243A{\rightarrow}G,\;1555A{\rightarrow}4G,\;7445A{\rightarrow}G)$ were not detected by polymerase chain reactions in any patients with noise-induced hearing loss, sensorineural hearing loss, and normal controls. The DNA sequencing of PCR products did not revealed an A to G substitution at nucleotide 3243, 1555, 7445 of mitochondrial DNA. The noise-induced sensorineural hearing loss was not associated with mitochondrial DNA mutation $(3243A{\rightarrow}G,\;1555A{\rightarrow}4G,\;7445A{\rightarrow}G)$.
