敎育機器의 利用에 對한 小考 : OHP의 效果的인 利用方法 Chiefly on the Effective Utilization of over Head project
張榮浩 대구교육대학교 1974 論文集 Vol.10 No.-
The over head project as one of the audio-visual teaching aids is apt to be overlooked because of a tendency that to use precision equipments is the essence of audio-visual method In many cases, the equipments are dully popularized or kept in dead storage, resulting from lack of understanding their characteristics and insufficiency of technical skill in using them. The purpose of this paper is to make acontribution to the enhancement of learning effects. To do this, the characteristics of over head project and the theoretical grounds of using the equipments were made clear, Various ways of T.P. making in which symbolic presentation of various contents is possible are brought up; such new and easy techniques as projection in light room and face-to-face exercise are presented.

Now is the time of technology. The importance of technology is gathering momentum and the tendency of mechanization and automation is being on the increase. Though there may be some who object to the automation of education from its traditional viewpoint, mechanized education must be accomplished for the modernized education. It is the human being who makes and uses machines. So through them, human nature should be fully matured. The development of VTR, Teaching Machine and computer will play a great role in the advancement of learning. Human engineering and practical science will be the important subjects education.
敎授-學習過程의 效率化를 위한 視聽覺 메시지의 考案과 活用에 관한 硏究
張榮浩 대구교육대학교 1979 論文集 Vol.15 No.-
The purpose of this study was intended as follow: 1) How much is the theorical basement of audio-viwual education established? 2) If the theory is scanty and poor, what is the reason? 3) In the teaching and learning process at information age, where is the key point of making them and their application of massage according to audio-visual materials (text and instrument) 4) In what degree, is the materials applied for? By the results: 1) The theorical foundation was poor and scanty. (by the Item 1∼15) 2) The reasons were: a) At teachers' college the subject of A-V education is selected one and only a part of students took the subject. b) In-service training, its role was not focussed on the materials and instruments at the informational age (by Item 20∼26) For the Promotion (by Item 26) For the exhibition (by Item 20, 31.7%) Therefore for the near futher; 1) For college students and in service training, the subject should be a required one. 2) It should be a long term way of teaching A-V education by making the materials for the professional, applying them and developing creativity for it. Furthermore, for the effectiveness of teaching learning, financial aids should be maintained for this materials for the national points of view.

소음성 난청이 증가하고 있는 요즈음 산업재해보상을 받은 근로자 111명을 대상으로연령, 근무경력 및 직업별로 분류하여 청력검사를 실시한 결과는 다음과 같다. 1. 순음청력역치 변화는 연령증가에 따른 청력손실의 증가는 없었으나, 근무경력에비례하여 청력손실이 증가하였으며 4,000Hz에서의 청력손실은 연령, 근무경력에관계없이 가장 심하게 나타났다. 2. 업무상 재해인정기준에 의한 6분식 평균청력역치 빈도는 연령, 근무경력 및 직업에관계없이 '보통 말에 의한 대화 불능자(31~40dB)'와 '소곤거림을 들을 수 없는자(41~59dB)'가 가장 많이 발생하였다. 6분식 평균청력역치 빈도는 인령과 근무경력에 비례하여 증가하였으며, 직업별로는 탄광업에 종사하는 근로자의 청력손실이가장 심한 것으로 나타났다. 3. 소음성 난청의 좌 ·우대칭성은 연령, 근무경력 및 직업에 관계없이 60%이상이 양측대칭을 나타내었고 그 외 연령으로 볼 때는 좌측 귀의 청력손실이 높았으나, 근무경력으로 볼 때는 좌 ·우측 귀의 청력손실이 동일하였다. 직업별로 볼 때는 좌측귀의 청력손실이 높았으며, 특히 탄광업의 경우 좌측 귀의 청력손실이 더욱 뚜렷하였다. Audiological evaluation was peformed for 111 employees who re-ceived industrial occupational disease compensation. Characteristics of noise-in-duced hearing loss were investigafed according to the various degree of age and occupational career and various kinds of job. The results obtained were as fol-lows ; 1. The average hearing level was slightly increased wtth increasing the deg-ree of occupational career. The average maximum hearing loss on the pure toneaudiograms appeared at 4,000Hz with no relation to the degree of age and occu-pational career. 2. According to the Standard level authorized by Ministry of Labor, incide-nce of noise-induce hearing loss was highly occurred at the level of 31 ~ 40 dBand 41 ~ 59 dB in all of experimental cases. Incidence of noise-induced hearingloss was increased with increasing the degree of age and occupational career.In various kinds of job, incidence of noise-induced hearing loss was the mosthighly occurred in the Coal-mining industry. 3. In the symmetricity of noise-induced hearing loss, symmetrical case ratewas over 60% in all of experimental cases. In case of occupational career, greaterhearing loss equally occurred in right or left ear. In cases of age and job, greaterhearing loss occurred in left ear, especially high in the Coal-mining industry.
