The zinc titanate sorbents(ZTG40) were prepared and the tests for durability and attrition resistance were carried out to develop the highly effective desulfurization sorbents. In the attrition tests for ZTG40 the results showed that the attrition resistance was 94.08% and that the sulfur capacity was maintained above 15g S/100g sorbent throughout the 100-cycle test, its maximum being 23.05g S/100g sorbent. As compared to sorbents developed by the developed countries, ZTG40 showed superior performances. In the advanced countries 15g S/100g sorbent is a yardstick of excellency for the sulfur capacity of desulfurization sorbents. Therefore, ZTG40 developed in this study has the desirable physical and chemical properties for fluidized desulfurization of coal gases.

중학교 영어교과서에 나타난 性차별 연구

朴商玉 弘益大學校 1986 弘大論叢 Vol.18 No.1

Sexism prevails in every part of our society. Although sexism had been taken for granted for so many years, concerned people came to realize that it must be eliminated once and for all, However, change does not come suddenly. Efforts should be made on a gradual basis. With that in mind, the purpose of this paper is to make a survey of the current middle school English textbooks in relation to sexism. As was expected, it was found that sexism exists in the textbooks. In other words, women are discriminated against men to a great extent in several aspects. First, more men are included in the title of each lesson than women. Second, there appears two times more men than women both in the content and in the picture of the textbooks. Third, there are four times more use of masculine pronouns than feminine ones when the sex is unknown. Fourth, more conversational exchanges are made between men than women or women and men. Fifth, five times more men are working in various kinds of occupations than women. For most of the time, women are working at home as housewives. Finally, women are depicted weak and passive, while men are strong, active, and intellectual, judging from the use of adjectives attached to each sex. It is concluded that the current middle school English textbooks must be revised so that there might be no more sexism.

전자렌지 조립작업자에서 발생한 경견완증후군의 조사 연구(Ⅱ) : 진찰 및 검사소견을 중심으로 A Review on the Findings of the Examinations

박종,김양옥,류소연,하상호,박병권 大韓産業醫學會 1995 대한직업환경의학회지 Vol.7 No.2

경견완증후군 소견자가 발생한 모 전자렌지 조립 작업장의 작업자 313명 중 설문조사에서 경견완 부위에 증상을 호소하는 137명(43.8%)에 대하여 건강진단을 실시하여 그 결과를 요약하면 다음과 같다. 1. 건강진단의 주요 소견 양성율은 자발통이 94.9%, 운동통이 62.0%, 근압통이 78.1%, X-선 촬영이상 54.7%, Morley검사 28.5%등이었다. 2. 남자에서 목부위의 근압통의 정도는 좌·우 악력과 음의 상관을 보였으며, 팔꿈치 부위의 근압통은 잔업량이 많을수록 증가하는 경향을 보였다. 여자에서는 목부위의 근압통의 정도는 좌·우 악력과 음의 상관을, 잔업량과는 양의 상관을 보였으며, 신장이 적을수록 손목부위의 압통을 심하게 호소하였다(p<0.05). 3. 근경결은 여성에서, 근무기간이 증가할수록 유의하게 증가하는 경향을 보였다.(p<0.01). 4. 건강진단 결과와 자각증상과의 연관성을 분석한 결과 X-선 촬영 이상여부는 목과 어깨의 통증, 다리의 피곤감과 관련이 있었다. 근경결 여부는 손, 손목, 손가락의 저림 증상과 유의한 관련이 있었고, Morley 검사는 손목과 손의 불편감, 등의 불편감이나 통증 등의 증상과 유의한 관련이 있었다. 목 부위의 근압통은 목과 어깨의 통증 그리고 손목, 손, 손가락의 저림 등과 유의한 관련이 있었으며 어깨 부위의 근압통은 목과 어깨의 통증, 전신 피로 증상과 유의한 관련이 있었다.(p<0.05). 5. 근압통이 있는 군에서 없는 군에 비해 일상 생활 도중에 겪는 고통 중 상지 부위의 고통 호소수가 유의하게 많았으며(p<0.05), 근전도 검사에서 양성인 경우 음성에 비해 신경정신계통에 나타나는 고통 호소수가 유의하게 많았다.(p<0.05). 결론적으로 경견완장해의 등급과 병형 진단에 있어서 자각증상과 건강진단 결과와는 밀접한 연관성이 있었으며, 근경결, 근압통, X-선 촬영 그리고 Morley 검사 등이 유용할 것으로 생각된다. 따라서 자각증상의 주관적인 요소를 가능한 한 배제할 수 있도록 자각증상을 객관화하는 노력과 방법들의 개발이 필요할 것으로 생각한다. To find the severity and the type of the cervicobrachial syndrome, through physical examinations and laboratory tests were made toward 137 patients complaining the cervicobrachial syndrome(CBS) through the health interview among 313 workers occupied in a microwave-oven assembling factory from December 1993 to February 1994. Results were as follows. 1. The prevalence of spontaneous pain was 94.9%, while 78.1% suffered from muscle tenderness, 63.5% suffered from muscle induration and 62.0% showed kinesalgia. 54.7% of patients showed positive cervical X-ray findings and 28.5% showed positive Morley test. 2. The muscle induration was associated with the total duration of the job among female workers. 3. The severity of neck tenderness was negatively correlated with the strength of the grip at both hands, positively correlated with the duration of overtime in male and the severity of the wrist tenderness was negatively correlated with the height in female. 4. X-ray findings, muscle induration. Morley test results, muscle tenderness on the neck and muscle tenderness on the shoulder were associated with subjective symptoms of the workers. 5. The muscle tenderness was associated with the number of the complaints at upper extremities among the sufferings in daily life significantly and the electromyogram(EMG) finding was associated with the number of the complaints about neuropsychological system among the sufferings in daily life significantly. In conclusion, the results of the physical examination were related with the subjective symptoms of the cervicobrachial syndrome. The muscle induration, the muscle tenderness, cervical X-ray findings and the Morley test results were more useful for the diagnosis of CBS. More efforts to objectify the subjective symptoms were asked.

대학 교양영어 교육의 방향

朴商玉 弘益大學校 1983 弘大論叢 Vol.15 No.1

In order to establish good course objectives, it is necessary for the educators to take students' needs into account. For this, student's needs assesment must come first before setting up any general and specific aims in education. The review of literature however, reveals that most colleges or universities, if not all, disregard needs of their students entirely in planning general English education programs. Realizing that it is the time we English educators should look into general English education curriculum, the paper repors the result of an experimental study through which materials about the needs of the students from Hong-Ik University were gathered. Several important findings were made: 1) Students responded that they needed to learn English badly and to study English subject very intensively for the first three years; 2) Students seemed to be stronger in instrumental motivation than integrative motivation; 3) Students felt that the English reading textbook did not meet their expectations in covering various kinds of interesting and contemporary works; 4) Students realized the necesssity of having the writing class as well as the laboratory class to improve their practical listening, speaking, and writing skill; and 5) it seemed that students were more or less homogeneous depending on to which college they belong. Under the assumption that the above findings would be applicable to most of the univesity students, the author suggests the following guidelines for better general English education programs which take students needs into account: 1) Students should be given at least four hours of English instruction per week during their freshmen years (two of them should be laboratory classes), three hours during their sophormore years, and two hours during their junior years, while they are allowed to take English as an elective during their senior years: 2) Considering that the ultimate aim of general education is to cultivate a well -rounded personality, students should not be motivated only instrumentally but be taught to be the intellectuals through appropriate selection and teaching of reading materials; 3) English writing classes should mostly focus on letter writing and free writing; and 4) individualized instruction, to some extent, should be implemented by differentiating instruction to different schools of students in a university.

대학 교양영어 교육의 개선을 위한 연구

朴商玉 弘益大學校 1989 弘大論叢 Vol.21 No.1

This paper proposes some specific ways to improve General English education program based on an experimental study during the fall semester of 1988. Freshmen classes for General English course had two levels. One of them, "H" class, was open to highly motivated students and the other, "0" class, to less motivated and/or less proficient students. Both of them studied the same basic English materials over the same period. "H" class students, however, dealt with other read-ing materials and participated in other classroom activities which integrated four English skills and culture. Statistical analysis of several pre-and post-written and listening tests indicated that "H" class students in general scored higher grades on all those tests and made more improvements than those of "O" class. "H" class students also showed more positve reactions about the experimental English program. It is concluded that Hong-Ik University should maintain 4 or 5 "H" classes in General English course for highly motivated freshmen and sophomores.

The granulation of sludge in the UASB reactor is beneficial to stable operation of the reactor at a high volumetric COD loading rate and high hydraulic loading rate, because it improves the setting ability of sludge and the granular sludge acquired has high methanogenic activity. The design of integral biogas?/liquid/solids seperators varies among suppliers of UASB technology. Comples, soluble organic compounds are the first to be hydrolyzed (Stage 1) to simple organics. These simple organics are converted by acid-forming bacteria to C₄H?COOH, C₃H?COOH, CH₃COOH, H₂ and CO₂ in a acidogenic phase(STAGE 2). The higher organic acids are subsequently converted to CH₃COOH and H₂(Stag 3) by acetogenic bacteria. The final step(Stage 4) to produce CH₃ is carried out by me-thano-bacterium. The kinetics of anaerobic digestion of paper wastewaters largely depends on the environmental conditions. The purpose of this study was to elucidate the kinetics of methane production from paper was tewaters in the UASB. A four-step reaction mechanism was proposed for modeling methanogenesis of anaerobic treatment of paper waterwaters.
