탁태오,김헌영,전형호,오용빈 江原大學校 産業技術硏究所 2004 産業技術硏究 Vol.24 No.B

The development of efficient and precise handling of an liquid crystal display (LCD) panel has been addressed as the sizes of LCD panels become much larger than ever. The majority part of LCD panel handling is conducted by industrial robots for the cost reduction and the quality control. A challenging problem, vibration of the panel, can be found when the robots are utilized for handling LCD panels. The vibration causes the poor product precision and the low productivity. The characteristics of LCD panels, which are the high size-to thickness ratio, the high elasticity, and the high brittleness, are the major sources of the vibration This paper introduces the vibration attenuation techniques to overcome the difficulties encountered in the LCD production using the industrial robots.

우리나라 장애인 고용부담금의 성격에 관한 연구

김용탁 한국장애인고용촉진공단 고용개발원 2006 장애와 고용 Vol.16 No.1

본 연구는 장애인의무고용제도를 됫받침하는 가장 중요한 제도 중의 하나인 장애인 고용 부담금의 성격을 짚어보고 그 속에서 어떤 문제점을 내포하고 있는가를 분석하는데 그 목적을 두고 있다. 먼저, 장애인 고용 부담금은 행정의무이행확보수단으로서의 성격과 유도적, 조정적 성격을 갖고 있는 것으로 분석되었다. 즉, 사업주들의 장애인 고용 의무를 이행시킴과 동시에 장애인 고용사업주와 미고용사업주간의 형평성을 도모하는 특성을 갖고 있다는 것을 알 수 있다. 그러나 실제 부담금 제도 운용은 많은 문제점을 내포하고 있다. 첫째, 부담금의 역할이 모호하다. 즉, 부담금이 장애인 고용을 촉진하는 제도로서 제 기능을 발휘하지 못하고 있는 것이다. 둘째, 부담금의 부담 기초액 산정 방법이 비합리적이다. 부담금 산정 원칙을 장애인 고용사업주와 미고용사업주간의 고용 손실 비용 보전에 두고 있으면서 실제, 부담 기초액은 장애인 고용에 따른 특별비용과는 별개로 산정되고 있다는 것이다. 셋째, 부담금 용도의 불명확성이다. 부담금의 납부 근거는 장애인 고용사업주에 대한 비용 보전임에도 불구하고 실제 용도는 장애인고용촉진및직업재활기금에 편입시켜 지출하고 있다는 것 이다. 마지막으로 장애인 고용 장려금의 지급기준이 부담 기초액 산정과 연동되고 생산성 손실에 대한 고려를 통해 지급되어야 함에도 불구하고 그렇지 못하다는 것이다. 부담금제도가 안고 있는 이러한 문제점을 해소하기 위해서는 무엇보다도 부담금에 대한 명확한 성격 규명과 그 성격에 합당한 제도의 개선이 이루어져야 할 것이다. Thls thesis examines the characteristics of one of the most important system supporting the employment quota system for the disabled, the employment levy system. The purpose of this study is to evaluate the problems of the current employment levy system. The employment levy system functions as a method to acquire administrative performance, inducement, and mediation, in other words, the levy system influences employers to employ people with disabilities as well as controlling economic burden between those employers hiring and not hiring the disabled. However, there are some problems in implementing the system. Flrst, the effects of the levy is ambiguous. The purpose of the levy system is to enhance the employment of the disabled. However, the actual effects are minimal. Second, the method of deriving the initial burden amount is unclear. The principle for deriving the initial burden amount is based on the need to preserve the employment cost generated by the employers that hire the disabled. Thlrd, the implementation of the levy system is unclear. Even though the purpose of the levy system is to preserve the costs of employing the disabled, in reality the levy is incorporated into the Employment Promotion and Vocational Rehabllltation Fund. Flnally, the basis for providing employment incentives does not take into account the loss of productivity. Thls should be linked with the initial burden amount. The principle of the employment levy system - derivation, process, and implementation - should be reexamlned to resolve the above mentioned problems.

한국탁,이규승,이은경,이용재,고광용,원동준,이정원,권순덕 한국환경농학회 2003 한국환경농학회지 Vol.22 No.3

대전시 노은 도매시장에서 채취한 6종의 채소류 중 농약잔류량을 조사한 후 이에 대한 위해성 평가를 실시하였다. 전체 100건의 분석시료 중 농약이 검출된 시료의 비율은 46.0%이었고, 잔류허용기준 초과비율은 6.0% 이었다. 검출비율이 높은 시료는 상추(85.0%), 깻잎(80.0%), 오이(60.0%) 순이었고, 상추 3건, 깻잎 3건이 허용기준을 초과하였다. 살균제는 dicar-boximide계, 유기염소계, azole계 농약, 살충제는 유기인계, 합성 pyrethroid계 농약이 많이 검출되었다. 검출빈도가 높은 성분은 procymidone, chlorpyrifos, chlorothalonil, cypermethrin, EPN의 순이었다. 위해성을 평가하기 위해서 각 농작물에 대한 농약의 추정 섭취량과 ADI를 비교한 결과, 허용기준을 초과한 깻잎의 bitertanol, triflumizole, iprobenphos가 다른 성분에 비하여 높은 비율을 보였다. 그러나 각 농산물의 식이섭취량이 적어 ADI에 대한 추정섭취량의 비율이 0.46%이하로 나타나 그 영향이 매우 낮은 것으로 판단되었다. Pesticide residues in some vegetables collected at Noeun wholesale market in Daejeon were surveyed and assessed their risk In 100 samples, the detection rate of pesticide was 46.0% and the rate exceed MRL was 6.0%. Commodities showing high detection rate were lettuce(85.0%), perilla leaf(80.0%) and cucumber(60.0%). Dicarboximide, organochlorine, and azole fungicides and organophosphorus and pyrethroid insecticides were detected. Detection frequency of pesticide was in the order of procymidone, chlorpyrifos, chlerothalonil, cypermethrin and EPN. When the estimated intake amount of the pesticides were compared with ADI to assess their risk, bitertanol, triflumizole and iprobenphos in perilla leaf were higher rate than the other vegetables. However the total amounts of intake of pesticides were estimated to less than 0.46% of ADI.

A study was conducted to investigate the seasonal changes in water quality of watershed in the Agricultural Environment Promotion Zone. samples collected were 12 GW (ground water), 2 IW (irrigation water), 2 SW (stream water) in An-Doug City, 4 GW, 6 IW, 11 SW in Young-Yang Gun, and sampling was conducted separately during dry and rainy season. In the ground water, EC and ionic species, except pH, were higher than those in stream water, and especially NO_3-N concentration exceeded the limitation of drinking water. Concentration of ions decreased as the sampling depth was far from the soil surface. During a rainy season, the concentrations of NO_3-N and K In the stream water were slightly higher than those during season. COD was lower during dry season in Yong-Yang, while the trend was contrasted to An-Doug. These results suggest that ground water was polluted by fertilization and compost while streamwater was polluted by loss of soil and organic during the rainy season. Principal chemical components related with changing water quality were EC, NO_3^-, Ca, Mg, Na, CI^-, SO_4^- in ground water, whereas NH_4-N, K, Mg, CI^-, SO_4^- in stream water.

Objectives : Using 3-stimulus auditory "oddball" paradigm reflecting fronto/central and temporo/parietal functions Simultaneously, we examined patients with schizophrenia. Methods : fifteen patients with schizophrenia from outpatient clinic and fifteen normal controls from hospital staffs were recruited for the study. To elicit P3a and P3b, 3-stimulus auditory oddball paradigm was employed. The 3-stimulus auditory oddball paradigm was composed of standard tone (1,000 Hz, 75 dB, 80%), target tone (2,000 Hz, 75 dB, 10%) and distracter (White noise, 95 dB, 10%). Results : P3a and P3b were prominent in fronto/central and temporo/parietal areas, respectively, in both schizophrenics and normal controls. The P300 amplitude in patients with schizophrenia was reduced across P3a and P3b (p<0.01). The P300latency in patients with schizophrenia was delayed across P3a and P3b (p<0.01). Conclusion : These results were consistent with frontal and temporo-parietal lobe dysfunctions in schizophrenics. The 3-stimulus auditory paradigm could be applied for patients with schizophrenia and useful for further exploration the disorder.

The distinctive features of post-modern age are caused by an information technology revolution; that means the advent of New Mass Communication Media. New Mass Communication Media is new electronic communication system such as Direct Broadcasting Satellite, Video, Teletext Television, Text Broadcasting High Definition Television, Community Antena Television, Picture Phone, etc. Today is the society which is ruled by New Mass Communication Media with electronic media not in phrase of Marshall McLuhan. The age of New Mass Communication Media has been already introduced into Korea. The supply of video cassette recorder is affected by '88 Olympic and extra carricular lecture on T.V for the matriculation has been increasing to 4 millions. The number of video production company and video distribution company is on the increase as 145 firms. Video programs which have been imported and made in the country run into 17,000 sorts since 1980. In 1989, 3,000 pieces of foreign video programs had been imported. However this abrupt increase brought about bottlenecks in management and social problems owing to the imports of the programs. This article deals with the system of distribution which Korea is confronted, the problem of main tendency of video program and the countermeasure.
