Although noise-induced hearing loss (NIHL) is the most prevalent occupational disease in Korea, only 10% of the diagnosed cases are compensated. Old (1989-94) and current diagnostic criteria, criteria for workers' compensation of NIHL in Korea, compensation formulas of American Medical Association/American association of Ophthalmology and Otolaryngology (AMA/AAOO), the Committee on Hearing, Bio-Acoustics, Biomechanics (CHABA), American Academy of Otolaryngology (AAO) recommendation were compared. Each criterion was applied on the audiomety data of 4044 workers (8023 ears), who had received the second line screening test of Special Periodic Health Examination Program for noise-exposed workers during 1991-2. First, the resulting proportions of NIHL cases by employing each criterion were compared and strength of agreement was measured using kappa value. Temporary Threshold Shift (TTS) was corrected by noise free interval, and the reduction ratio of NIHL cases was calculated. Theoretical progression model of NIHL was reconstructed from previous studies on the natural course of NIHL to evaluate the change of diagnosis result of each criterion in the model. The kappa value between old and current criteria was 0.19, 0.55 for current criteria and workers' com. criteria, ranging from 0.08 to 0.78, highest coincidence was observed between current criteria and CHABA formula. The current criteria produce most similar results with CHABA formula. If TTS is corrected for NFI, there is about 14% reduction of NIHL cases. The results of applying on NIHL progression model divided the formulas roughly into 3 groups, of which compensation criteria was the most, old criteria and AAO the least conservative. In conclusion, the result of 4 ㎑ audiometry should be excluded in evaluation of hearing level and a new hearing conservation program should be set out. Current diagnostic criteria has an ambiguity in that managerial concept for prevention and purpose of compensation is mixed up. The current diagnostic criteria and compensation criteria could be incorporated into a new formula which is based on the state of the art test for estimating everyday hearing disability.

한장호,김석영,윤여창,이시경 한국응용생명화학회 2003 Applied Biological Chemistry (Appl Biol Chem) Vol.46 No.4

Puff pastry의 제조 공정에서 pastry 마가린 함량과 적층 수의 변화가 제품의 수분 함량, 굽기 손실, 부피, vapor action 등에 미치는 영향을 조사하였다. Pastry 마가린 함량이 90%로 동일하고 적층 수가 27결일 경우 10.8±0.6%의 수분 함량을 나타냈으며, 1024결일 경우 16.7±0.3%로 적층 수가 증가할수록 제품의 수분함량은 증가 하는 경향을 보였다. 적층 수를 256결로 동일하게 하고, pastry 마가린 함량이 50%일 경우는 17.3±0.5%로 나타났으며, 130%에서는 7.5±0.2%로 pastry 마가린 함량이 증가할수록 제품의 수분 함량은 감소하였다. Pastry 마가린 함량을 70%로 동일하게 했을 때 굽기 손실의 변화는 27결일 경우 25.0±0.7%로 나타났으며, 1024결일경우엔 18.8±0.6^로 나타나 적층 수가 증가할수록 제품의 굽기 손실은 감소하는 경향을 보였다. 적층 수를 27결로 동일하게 한 경우에서는 pastry 마가린 함량이 90%일 때 25.4±0.4%의 굽기 손실이 발생하였으며, 110%에서 26.9±0.4%로 굽기 손실이 가장 높게 나타났다. Pastry 마가린 함량이 130%이고 적층수가 81결일 때에 21.87±0.79㎖/g로 최대의 부피를 나타내었다. 또한 vapor action의 크기는 9.15㎜가 pastry 마가린 함량 110%, 적층 수 256결에서 8.25±0.50개로 가장 많이 나타났다. This study was carried out to investigate the effect of pastry margarine content and number of layers on moisture content, baking loss. specific loaf volume and the vapor action in the manufacturing process of puff pastry. As the number of layers of the puff pastry increased the moisture content of the products slightly increased. And the moisture contents of the products decreased, as the pastry margarine contents of the puff pastry increased in the same number of layers. The baking loss of the products tended to decrease as the number of layers increased. On the other hand, as the pastry margarine contents of the puff pastry increased, the baking loss of the product increased. When the pastry margarine content in puff pastries became 130%, 81 layers provided the maximum specific loaf volumes 21.62±0.79 ㎖/g of puff pastries. When 110% of margarine and 256 layers were applied for preparation of puff pastry, the number of vapor action was 8.25±0.50 with the vapor action size of 9-15 ㎜.

유기용제 사용 소규모사업장의 체계적 건강관리 프로그램 개발에 관한 연구1) : 신경행동학적 검사법의 적용 가능성 Application of Neurobehavioral Core Test Battery(NCTB)

한상환,하미나,권호장,윤덕로,조수헌 大韓産業醫學會 1995 대한직업환경의학회지 Vol.7 No.2

It is known that there appear some nonspecific and delicate changes in neuropsychiatric aspect on the workers when they are exposed for a long period to low concentrated organic solvents in the work places. Therefore, it gives rise to the necessity of developing a program for the health supervisor stationed in the work place to supervise these neurobehavioral health affection. In addition to the questionnaire posed to the workers exposed to organic solvents, the study team conducted NCTB(Neurobehavioral Core Test Battery) respectively on an exposed group and a non-exposed group to organic solvents. The study team compared the results and decided whether or not to apply the results to the evaluation program of health affection. The study team divided 132 workers in 6 car repairing factories and 2 textile printing factories into exposed group and non-exposed group, pairing them off into 66 research objects according to their age, sex, and job. Neurobehavioral test was conducted on 6 items, except the POMS test, of NCTB developed by the World Health Organization(WHO). The study team conducted examinations of working environment on the exposed and non-exposed groups of each work place. The analysis of the collected materials for examinations were conducted with GC-MS. The concentration of the mixture in the air, relative to their respective threshold limit values(TLV) was calculated according to the formula of the ACGIH and the Korean threshold limits. The results indicated that for two of eight factories samples the recommended concentration limits for mixtures was exceeded. Of the six tests, the 'digit span forward', 'digit span backward' and 'digit symbol' produced conspicuous statistical differences between the two groups(p<0.1) as a result of compairing the test values by means of paired t-test. The results of respective analysis of the car repairing factories and textile printing factories revealed that the textile printing factories had greater differences between the exposed and the non-exposed than in the car repairing factories. It is presumably because the textile printing workers are continuously exposed to the organic solvents during working hours, whereas the car repairing workers are exposed only when they are doing painting works, The NCTB is assessed very useful in examining the neurobehavioral health affection under the exposure to organic solvents, and, therefore, the study team expects that the NCTB will play an important part in the course of developing a health program for the workers exposed to organic solvents.

본 연구에서는 인터넷 광고에 대한 소비자들의 시각적 주의를 검증하기 위해 아이 트래커로 실험을 진행하였다. 인터넷 포털 사이트에서 실제로 집행된 광고를 실험 자극으로 선정하였으며, 광고 속성들과 소비자들의 인터넷 사용 목적이 시각적 주의에 영향을 주는지 검증하고자 하였다. 본 연구에서는 자극유형(텍스트/그림), 부분적 겹침(있음/없음), 상대적 높이(상/중/하), 대조(강/중/약), 광고자극 내 대조(강/중/약), 광고 위치(좌/우)의 자극 속성들과 과제 조건(유/무)의 주효과 및 상호작용을 검증하고자 하였다. 연구결과 자극 속성인 광고 제시 유형, 대조, 광고 자극 내 대조와 과제 탐색은 각각의 주효과와 상호작용 효과가 모두 유의미하였으나, 부분적 겹침, 상대적 높이는 상호작용만 유의미하였다. 한편, 뇌의 반구 처리 유형에 의한 그림/텍스트 광고의 좌우 위치 효과의 결과는 가설과 일치되지 않는 결과를 나타내었다. The purpose of this study was to examine the attention to the internet ads of consumers. Unlike the prior studies, this study was collected the eye fixation data of participants through the eye tracker apparatus. The results showed that the participants attended to the ads as a result of activating top-down processing, caused by their goal of using internet and learned visual searching route. In addition, each type of ad(pictorial and text) was gathered different visual attention as a result of bottom-up process and was interacted with goal of using internet. And stimuli attributes in the ads, like partially occlusion and contrast led to participants’ attention to the ads differently. But relative height in the visual field had no significance and locations of ads didn’t have correspondent results. Finally, limitations of this paper and future research directions were discussed.

The objective of this research on the sports activities of primary school students who are representative of our region and their academic achivement is to nomalize physical education. operate ideal sports activities and provide the basic materials and information needed for guidance. The subjects of this research amounted to 575 primary students including 239 in individual events. 336 in group events who participated in The 26th Youth Sports Competition. The results of research was as follows : It is found that they start sports by the recommendation of their teacher or coach. or their own willingness. And their average training lasts. ranging from a minimum of 2-3 hours to a maximum of over 4 hours. Most school have intensive training course for competition and 60% of them execute programs of over 3 weeks. Under supervision. the players seemed to perform better and most students answered that they would like to quit after graduation When the students were asked “If you don't have intensive training. will you attend classes?" 59% of them responded that they would attend both morning and afternoon class. 31% of them say that they would attend only the morning class According to this research. They responded that they wouldn't go to class or go to morning class. if they participated in intensive training courses. Even if they attended the class. they have no inclination to preview or review. After competition was over, the percentage of students who like to study corresponds with that of students who don't .If they said they have a interest in studying. the reason was that they liked to study with friends. And if not, the reason was that they couldn't catch up with their class. exhaustion and lack of concentration.

권호장,하미나,김돈규,백남종,조수헌,한태륜 大韓産業醫學會 1998 대한직업환경의학회지 Vol.10 No.4

As use of the visual display terminal(VDT) is becoming more generalized as a result of office automation, the so-called 'VDT syndrome' which is often observed with the workers using VDT has emerged as a serious occupational health problem. However, few comparative study with control group using not only subjective symptom but also physical examination has been conducted. We have conducted a study comparing prevalence rated of musculoskeletal disorder between 113 VDT operators of a telecommunication company and the control groups of housewives and office ladies through a review of subjective symptoms as well as physical examination by physiatrist to understand the magnitude of problem and relative risk of VDT worker. The symptom rates of upper extremity disability in VDT operators were higher than those of controls especially in neck and shoulder area. Fifty-four(47.8%) of 113 VDT operators met our case definition of upper extremity disorder by subjective symptom and physical examination. Myofascial pain syndrome of neck and shoulder muscles were the most common(46.9%). The odd ratio of using VDT operation for developing myofascial pain syndrome in the neck or shoulder area were 2.52(compared to controls of office ladies) and 2.64(compared to controls of housewives). Other anatomical lesion such as elbow, hand and wrist shows slight higher prevalence rates of musculoskeletal disorder than control groups but not statistically significant.

진공증착방법으로 제작한 Ni53-Fe47 박막에 관한 신형전류자기 기전력효과의, 전류와 자장 방향이 만드는 각θ의존성이, 자기저항효과의 cos 2θ, Hall 1효과의 경우 sin θ임에 대하여 sin 2θ로 관측되고, 이 효과의 자장에 의존하는 전압변화율이 자기저항효과와 비교할 때 차수가 다르게 큰 것이 조사된다. 이 효과가 2 Carrier형 모델로 이해 할 수 있음을 이론적으로 확인된다. A new Galvanomagnetic electromotive force effect of Ni53-Fe47 thin films is studied. The dependence of this effect on θ, angle between the current and the magnetic field, is found to be the form of sin 2θ, in contrast with that of the magnetoresistance effect cos2θand that of the Hall effect sinθ. Property of this effect is that 1the rate of the voltage variation depending on the magnetic field is extremely large as compared with the magnetiresistance effect. It is theoretically confirmed that this effect is well understood on the basis of the two carrier types model.

Objectives : We performed this study to assess the needs of the chronically mentally ill(CMI) from the perspectives of the consumers(patients) and the providers(therapists) and to compare the differences between them. We also aimed to find met needs and unmet needs and then to determine the priority of the mental health services for the CMI. Methods : 165 patients and 19 therapists were examined with need assessment tool which had been developed by authors. Through statistical analysis, we evaluated the degree of problem, the degree of intervention, the relative degree of problem, and the degree of demand in each areas of needs, and compared the differences between patient group and therapist group. After then met needs and unmet needs from the perspectives of each group were revealed. Results : 1) There were differences in the assessment of needs between patients and therapists. 2) The more problem areas assessed by patients were finances, mental health, occupation, and leisure life in order of higher ranks. While occupation, leisure life, mental health, and finances were assessed as highly ranked problem areas by the therapist group. 3) Patients perceived that they were given more helps from others in the areas of mental health, physical health, accommodation, and relation to family than other areas. From the perspective of therapists, the areas of needs such as mental health, basic knowledge, occupation, and interpersonal retation were highly ranked intervention areas. 4) The demands for daily living skill, occupation, finances, accommodation were ranked highly by patient group. Highly demanded needs assessed by therapist group were mental health, occupation, interpersonal relation, and basic knowledge. 5) Unmet needs assessed by patient group were occupation, finances, and accommodation, while by therapist group, occupation. Conclusions : The needs of the CMI were assessed and identified by the consumers(patients) and providers(therapists) with the same tool. The differences between two groups were revealed. The most important unmet need of the CMI was occupation. These results can be used to plan the priority of mental health services and policies.
