The major purpose of this study was to have students improve their learning ability in technology subject through the understanding of the students' learning achievement effect causing from specific explanation about foreign-terminology in high school technology subject. Students were divided into two groups. On group was the specific foreign-terminology explanation group(experimental group), and the other group was the traditional instruction group(control group). Each group also was classified into two groups, high grade group and low grade group. To clarify the high and low group, middle range grade students were eliminated. So the 4 groups(EH: experimental high, EL: experimental low, CH: control high, CL: control low) were used in this study. The results of the study were (1) There was statistically strong evidence(F=10.69, p=0.0013) that the experimental group and the control group were different in learning achievement on the subject. The experimental group showed much high score on the test than the control group did. (2) There was no evidence(F=0.64, p=0.43) that the EH group and CH group were different in arning achievement on the subject. (3) There was also no evidence(F=0.23, p=0.63) that the EH group and EL group were different in learning achievement on the subject. (4) There was statistically strong evidence(F=9.89, p=0.0021) that the EL group and CL group were different in learning achievement on the subject.

이청담의 불교정화 정신과 조선불교학인대회

김광식 진주산업대학교 2004 청담기술연구소 Vol.2004 No.-

한국 현대불교사의 중심 사건이며, 조계종단의 재정비를 기한 것은 불교정화운동이다. 본 고찰은 불교정화운동을 상징하는 승려인 이청담의 정화정신의 실체를 찾아보고, 그 정신이 언제 구체화되었는가를 설명하였다. 즉, 그의 불교정화의 근본은 무엇이고, 왜 그는 불교의 정화를 치열하게 강조하였는가를 살펴보았다. 이청담의 불교정화는 교단정화, 신도정화, 사회정화라는 구도를 갖는다. 이 구도하에서 그의 불교정화 정신은 우리 민족의 역사와 얼이 담긴 불교의 정화 및 재건이었다. 이를 위해서 최우선적인 것이 수행자 중심의 승단을 만드는 것이었다. 그런데 이러한 그의 불교정화는 그가 승려 초기 시절인 1928년 3월, 각황사에서 개최된 전국학인대회에서 본격화되었다. 당시 그는 불교개혁을 위해 전국 강원의 학인들을 결집시켜 대회를 주도하였다. 즉 그는 불교정화를 위한 불교교육의 개혁을 강조 학인대회를 준비, 주관하였다. 요컨대 이청담이 입산출가한 1925년부터 입적한 1971년까지 불교정화라는 정신이 그의 일생을 관통하였던 것이다. It was the Buddhist purification movement that was a central event of the Buddhist history in Korea and gave improvement in Jogye order. This study sought for the substance of venerable Chung-dam's purification mind or the symbol of Buddhist purification movement and explained when the mind was materialized. Namely, it deserves special emphasis on what is the foundation of Buddhist purification and why he emphasized it particularly. His Buddhist purification consists of a religious order, a Buddhist and a society purification. This is to say, his Buddhist purification was the purification and reconstruction of Buddhism containing our people's history and spirit. In order to do this, it was required to make the religious order leaded by Buddhists first of all. However, during the years of a Buddhist priest, his thought was really unfolded in the national conference for Buddhist students(people who are in the progress of practice) held in 1928, March in the Gakhwang temple. At the moment, he gathered Buddhist students from national temples for Buddhist reformation and supervised the national conference. In other words, he prepared and supervised it in order to emphasize the reformation of Buddhist education for Buddhist purification. After all, the spirit of Buddhist purification played an important roll in venerable Chung-dam's life from entering the Buddhist priesthood in 1925 to nirvana in 1971.

Primary unruptured appendiceal mucocele is a rare disease. It is very difficult to diagnose preoperatively because of the rarity of classical symptoms and low incidence. Usually it is discovered incidentally during abdominal ultrasonography(US), computed tomography(CT), or appendectomy for acute appendicitis. If untreated, one type of mucoceles may rupture producing a potentially fatal entity known as pseudomyxoma peritonei, therefore preoperative diagnosis is very important. With the advent of colonoscopy, abdominal US and CT, it has been possible to preoperatively diagnose mucocele of appendix. We experienced a case of appendiceal mucocele in a 60 year-old woman who had symptoms of lower abdominal discomfort and right lower quadrant abdominal pain, and it was diagnosed preoperatively by colonoscopy, abdominal US and CT. So we present this case with review of literature.

The purpose of this study is to substitute water-based painting materials for the current solvent-based ones used in motor-repairing process to minimize the exposure of organic solvents to the painters. This study assessed the exposure of organic solvents to the painters using water-based and solvent-based painting materials and compared compositions, painting processes and the health hazards of the application of these alternative painting materials. The results of this study are as follows. 1. solvent-based painting materials used in motor-repairing process consist of various organic solvents, which consist primarily of toluene, xylene, ethyl benzene, ethyl methyl bezene, trimethyl bezene, ethyl acetate, butyl acetate, methyl isobutyl ketone, 2-ethoxy ethanol, 2-ethoxy ethyl acetate and toluene-2.4-diisocianate and the others. These organic solvents are know as health-hazardous substances. But water-based painting materials are high-solid, low-solvent ones and consist of such two organic solvents as 2-butoxy ethanol and 2-heptanone and the others. 2. The painters using solvent-based painting materials in motor-repairing process are exposed to various organic acetate, methyl isobutyl ketone, trimethyl benzene, 2-ethoxy ethanol, and 2-ethoxy ethyl acetate. But the painters using solvent-based ones are only exposed to 2-butoxy ethanol and 2-heptanone. 3. By using water-based painting materials in stead of solvent-based painting materials containing health-hazardous organic solvents, the exposure of such organic solvents in the painter's breathing zone can be largely prevented. 4. This study recommends water-based painting materials as substitutes for the current solvent-based ones used in motor-repairing process to minimize the exposure of organic solvents to the painters.

Endometriosis is the abnormal growth of endometrial tissue outside the uterine cavity. Endometriosis in the abdominal scar following cesarean section is very rare condition among the extrapelvic endometriosis. The frequency of abdominal wall endometriosis secondary to cesarean section is from 0.03% to 0.8% in some reports. It is difficult to diagnosed in spite of the typical symptoms. The typical symptom is aching swelling in the area of the surgical scar, which is influenced by the phases of menstruation. The definitive diagnosis is established by pathologic analysis. Surgical excision remains the treatment of choice. The majority of patients presented from 1 to 2 years after the precipitating operation. We experienced an unusual case of abdominal wall endometriosis presented over 10 years after cesarean section, who was admitted to our hospital complaining of recurrent left lower abdominal pain. So, we report this case with a brief review of the concerned literatures.
