As the technical medium evolves, the method of accepting information is changing. The technical medium also appears in various ways through the combination with art. This study aims to conduct research on how hypermedia, appearing from this, will reveal itself in the urban public design in terms of its expression mode. First, this study looks at the characteristics for expression representation of hypermedia art through theoretical considerations on the hypermedia. Second, this study identifies how hypermedia art is introduced in the urban public design through art cases. Third, this study reveals the characteristics depending on the expression mode of hypermedia art shown in the urban public design based on the analyzed cases. As a result, first, hypermedia appeared in various image lighting expression modes that use 'light' in the urban public design and interacted with the public. Second, hypermedia reacted to 'motion' and was the expression mode of using bodies in the urban public design and using peripheral devices and external environment and characterized by having complex patterns of multi-layered structure through multi-media. It also applied sight, hearing, and touch partially or integratedly to attract synesthesia from the public and checked mutual interaction rapidly in an improvised way. Third, such a complex digital technology was the network expression mode beyond space and time by medium of urban public design and characterized by the new experience of virtual space expansion through the world wide network and the communication mode of participation. With such a role change of media and combination with art, hypermedia has been achieving varied extended representations. It is considered to change our monotonous urban environment, restore our relationship with the public, and open a new field of communication. Accordingly, the significance of this study can be identified through how it aimed to display the expression method of hypermedia which caused its extension in the field of urban public design as well as through the derivation of relevant characteristics.

In effort to determine whether aircraft noise can have health effects such as hearing loss, hypertension and psychological stress, a total of 111 male professors and administrative officers working a college near a military airport in Korea(exposed group) and a total of 168 males and 112 females matched by age groups(control groups) were analyzed. Personal noise exposure and indoor and outdoor sound level of jet aircraft noise were measured at the exposed are3. And pure tone, air conduction test and measurement of blood pressure were given to the exposed(males) and matched control groups (males and females). BEPSI(Brief Encounter Psychological Instrument) and psychological response to aircraft noise were examined for the exposed group. The noise dosimetry results revealed time-weighted averages(TWAs) that ranged from 61 to 68 dBA. However the levels encountered during taking off jet airplanes reached 126 dBA for two half minutes time period. Th, audiometric, test showed that mean values of HTL(hearing threshold level) in exposed group at every frequency(500, 1,000, 2,000, 4,000, and 8,000 Hz were much lower than them of male and female control groups. And in old age groups, interaction of age and noise was observed at 8,000 Hz in both ears(p<0.05). Conclusively, aircraft noise does not appear to induce hearing loss directly in high frequency, but may decreased hearing threshold level by interaction of aging process and noise exposure. However, difference of mean values of exposed and control groups on blood pressure was not significantly. In psychological test, annoyance was the most severe psychological response to noise in exposed group, but mean value of BEPSI was not correlated with job duration in exposed group.

이 연구는 특수건강진단기관의 소음성 난청 진단결과의 유소견자$(D_1)$와 요관찰자(C)를 하나의 평가 지표로 설정하여, 첫째 소음 특수건강진단 결과 소음성 난청의 실태 파악, 둘째 소음성 난청 요관찰 자의 청력장애 평가, 셋째 정력장애 정도 에 따른 각 주파수 영역별 기도순음청력 검사 결과를 통해 청력손실의 정도를 파악하고 이의 판정기준에 따른 진단의 적정성을 검토하고자 하였다. 1. 1994년 l월부터 12월까지의 73개 특수건강진단기관의 특수건강진단 실시 사업장은 27,347개이며 이중 소음 특수 건강진단 설시 사업장은 16,388개(59.9%)이었으며, 전체 특수건강진단 수진 근로자는 731,029명이며 이중 소음 특수 건강진단 수진 근로자는 343,457명 (47.0%)이었다. 소음성 난청 요관찰자는 38,058명, 소음성 난청 유소견자는 1,358 명으로 소음성 난청 요관찰률은 11.1%, 유소견율은 0.44%이었다. 지역에 따라 소음성 난청 요관찰률의 차이를 보여주며 판정기준의 적용에 따른 기도순음 청력평균손실치가 일부 적정하게 판단되지 못하였음을 보여 주었다. 2. ISO 기준의 3분법에 의한 청력 평가시 97%가 경도난청 이하였으며, 회화음 역에서의 4분법에 비해 거의 비슷하였으나 약간 정상역이 많았고, 고음역을 포함하여 평가하는 4분법과 6분법의 적용시 정상자의 경도난청으로의 가능성이 높다고 볼 수 있어 청력평가시 평가방법의 적용에 따라 내재적인 판별능의 차이를 보여준다고 볼 수 있다. 3. 우측귀의 청력역치를 ISO 기준에 의해 평가한 후 양귀의 청력역치의 분포 및 차이를 보면, 우측귀의 평균역치(표준편차)가 20.54(9.56) dB, 좌측귀의 평균역치가 20.54(9.57) dB로 좌측귀의 평균역치가 우측보다 높았다. 양귀의 청력이 75.4%에서 정상역이었으며, 21,562명 (90.6%)의 양귀 청력역치 차이의 범위가 10dB이내였다. 4. 소음성 난청 요관찰자의 회화음역에 속하는 500, 1,000 및 2,000 Hz에서의 기도청력역치를 산술평균으로 하여 구하는 3분법의 청력손실도(표준편차)를 주파수 별로 보면, 우측귀에서 500 Hz 21.08(10.23), 1,000 Hz 18.44(10.01), 2,000 Hz 22.09(13.46), 4,000 Hz 52.36(16.38) dB이었다. 평균청력손실도를 10 dB 간격으로 구분한 후 각각의 주파수별 청력역치를 살펴보면, 정상역인 20 dB미만에서 고음역인 4,000 Hz에서 회화음역인 500, 1,000 및 2,000 Hz에서 보다 평균 30-40 dB 이상의 역치를 보이는 $C_5-dip$ 현상을 특징적으로 보였다. 평균정력손질이 증가함에 따라 4,000 Hz에서의 역치 증가 현상이 점차적으로 감소하다 평균청력손실이 50 dB 이상에서는 10dB 내외의 차이만을 나타내었다. 이상과 같이 소음성 난청 요관찰자에 대한 분석에서 소음성 난청의 평가방법 에 따른 실태와 의미, 소음에 의한 조기청력손실의 특정과 소음성 난청의 판정기준에 따른 진단의 적정성을 확인할 수 있었으며, 소음성 난청 요관찰자에 대한 관리의 필요성을 제언할 수 있겠다.

과거 군 복무 기간 동안 청력에 영향을 미치는 사격 및 포격 등 소음에 노출된 군 경력이 현재 소음 노출 근로자에게 어떤 청각학적 영향을 미치며, 소음성 난청의 발생과 관련이 있는지를 평가하고자 하였다. 중소규모 선박수리 및 건조업체 15개 사업체 440명을 대상으로 근로자의 일반 사항, 임상증상, 현재의 청력과 관련한 과거 이과적 병력, 군 복무시 충격소음의 상시적 노출 등의 군 경력, 이명 등의 자각증상에 관한 설문조사와 순음청력검사 및 중이검사를 시행하였다. 현 직종에서의 소음 노출군 중 과거 군에서 소음 노출군이 각 주파수별 청력역치와 평균 청력역치가 가장 컸으며, 특히 2-8kHz의 주파수 역치에서 차이가 크게 나타났다. 청력손실자의 비율 및 중증도의 정도가 현 직종에서의 소음 노출군 중 과거 군에서 소음 노출군이 가장 높은 비율을 보였으며, 특히 감각신경성 난청으로서 소음성 난청자가 통계적으로 유의하게 더 많았다. 이명은 현재 소음 노출 직종에 있는 군에서 높았으며, 그중 군 소음 노출군이 46.2%로 유의하게 더 높았다. 소음성 난청 여부를 종속변수로 한 로지스틱 회귀분석 결과, 연령, 현 직종 근무기간, 군 소음 노출력, 현 직종에서의 소음 노출 여부가 유의한 독립변수로 작용하였다. 우측 귀의 경우, 소음성 난청에 대한 군 소음 노출력의 비차비는 4.5이었고, 현 직종의 소음 노출의 비차비는 7.9이었다. 군 소음 노출 및 현 작업 소음 노출 여부에 따른 각 군별 좌우측 귀의 4 kHz 청력역치와 평균 청력역치는 I군에서 좌우측 귀 모두 나이 및 근무기간이 증가할수록 가장 크게 영향을 미치며 유의하게 증가하였으며 II군, III군, IV군 순으로 청력 역치가 증가하였다. 군에서 노출되는 충격소음은 청력손실과 이명 등 청각학적 영향을 미치며 사업장에서 소음 노출에 따른 소음성 난청의 발생에도 부가적인 영향을 미친다. 따라서 군에서의 소음 노출에 따른 청각학적 영향을 예방하기 위해서뿐만 아니라 소음 노출 근로자에 대한 청력 관리 측면에서도 이의 조기 진단, 치료, 보상 및 재활을 위해서는 군에서의 소음 노출 문제까지 함께 다루어야 함을 시사한다.

Assessment in Socio-economic items should be used to estimate social influence when policies and projects were introduced. To estimate current situation of socio-economic items 19 Environmental Impact Statement (EIS) of large scale projects were analyzed. The projects were selected based on magnitude of social impact when the projects were implemented. Environmental Impact Statement was categorized into line projects(road construction, railroad construction, stream development, etc), and surface projects(energy development, wetland reclamation, recreation and sport development, and housing and residential development, etc) thus being chosen for 19 projects in each categories. This report was based on the analysis of 7 items in socio-economic environmental items(i.e., population, residents, industry, public facilities, education, transport and historical monument). Most EIS did not follow the regulation suggested by Ministry of Environment, and only current circumstances were briefly described. Indifference of in-depth analysis of socioeconomic environmental items would influence the process of social and environment impact negatively in the midst of construction of National Projects such as Outer Circle Seoul Highways, Saemankeum Reclamation Projects, etc. This abrupt halt of construction was mostly based on a lack of public hearing or public participation. Socio-economic items are also very much lacking in quantitative method and strengthening socio-economic environmental items is needed via checklist or matrix that brings decision-makers better ideas objectively.

A review study was conducted to examine the adverse effects of styrene, styrene mixtures, or styrene and/or styrene mixtures and noise on the auditory system in humans employed in occupational settings. The search included peer-reviewed articles published in English language involving human volunteers spanning a 25-year period (1990-2015). Studies included peer review journals, caseecontrol studies, and case reports. Animal studies were excluded. An initial search identified 40 studies. After screening for inclusion, 13 studies were retrieved for full journal detail examination and review. As a whole, the results range from no to mild associations between styrene exposure and auditory dysfunction, noting relatively small sample sizes. However, four studies investigating styrene with other organic solvent mixtures and noise suggested combined exposures to both styrene organic solvent mixtures may be more ototoxic than exposure to noise alone. There is little literature examining the effect of styrene on auditory functioning in humans. Nonetheless, findings suggest public health professionals and policy makers should be made aware of the future research needs pertaining to hearing impairment and ototoxicity from styrene. It is recommended that chronic styrene-exposed individuals be routinely evaluated with a comprehensive audiological test battery to detect early signs of auditory dysfunction.

Background: This study examined the effect of having a usual source of care on the degree of patient-centered communication among persons with disability. The role of the usual source of care has been emphasized to improve patient experience, especially for patients with complex health conditions. Methods: This study used the 2017-2018 Korean Health Panel data, and the final study observations were 22,475 (20,806 people without disability and 1,669 people with disability). We applied generalized estimating equation model to show the effect of having a usual source of care on patient-centered communication, and subgroup analysis considering the types and severity of disabilities. Results: Persons who have disabilities, compared with ones without it, significantly had more usual sources of care (32.4% vs. 24.6%). By type of disability, persons with mental (51.4%), internal organ (43.8%), visual (37%), and physical disabilities (31.6%) had more usual sources of care than hearing/speech (26.6%), and developmental disabilities (18.6%). The average score of patient-centered communication was higher among who had a usual sources of care (3.2 vs. 2.7), and the regression analysis showed that having a usual sources of care was positively associated with higher patient-centered communication score (𝛽=0.476, p<0.05). However, the positive effects of usual sources of care was not observed among persons with severe hearing/speech, developmental, and mental disabilities. Conclusion: This study showed that role of patient-centered communication was limited in persons with severe hearing/speech disabilities, developmental, and mental disabilities. The education programs and supports are needed to improve communication skills between medical staff and persons with specific types of disabilities.

It is essential to develop legal and legislative devices like the National Environmental Act to conduct systematic and continuous environmental education. In many Countries including the Uinted States, Great Britain, Germany, and Australia, environmental education has been developing based on legal and legislative systems. Of those cases, the Uintes States made efforts to promote environmental education through legislation, which can have significant implications for us with intention to legislate the National Environmental Education Promotion Act. This study is focusing on our environmental education by studying the histiry and current situation of National Environmental Education Act, PL 91 516 of the United States and its features. In case of the United States, there has been several amendments and re-approvals. since the first National Environmental Education Act was legislated. The public hearing for the re-approval of National Environmental Education Act whIch was legislated in 1990 was held during the Summer of 2000. This gave us important reference data including the need of environmental education, its effects, and considering articles. As a result of the public hearing, 1990. National Environmental Education Act was recognized and some articles were amended. Its re-approved as John H Chafee Environmental Education Act of 2001, PL 107-S 876 IS Some implications and suggestions were drawn from the case study, which included the importance of related ministries, financial support, the role of Consulting Committee and Special Committee for environmental educators, environmental education program certification system.

Purpose: This study aims to make suggestions for the implementation of the job-based dental technician practical exam. Methods: The duties of dental technicians and the recent trends in the dental technician field were defined and identified, respectively, to achieve the purpose of the current study. The practical test system of domestic and foreign national tests was comparatively analyzed to seek improvements. Additionally, the direction of the practical test to be taken in the future was investigated through a public hearing of domestic experts. Results: As a result of this study, the job site of dental technicians was recently found to be undergoing many changes, and it can be observed that related laws and the work site have already changed. Comparison of overseas test systems showed that Korea was limited to a rather small evaluation range; in general, the scope of the evaluation of the practical tests in foreign countries was widely conducted. In the results of the public hearing, opinions exist that the evaluation range of the practical test was expanded and that new subjects were needed, but the opinion on the existence of practical difficulties was mainly mentioned. Conclusion: The evaluation range of the current practical examination subjects should be expanded and the evaluation of digital dental engineering subjects should be added to proceed with the job-based practical examination. However, it seems that efforts should be made gradually through various efforts in the future due to practical difficulties.
