This paper describes the characteristics of pressure in the exhaust system. Exhaust system of gasoline engine consists of an exhaust manifold, a primary and a secondary muffler and a 3-way catalyst. And these compositions are tested in the before and behind of each composition. The pressure waves of burnt gas generated in the 4 stroke and 4 cylinder engine are formatted tatal eight pressure waves during the one cycle. The first pressure wave is generated by blowdown and the second pressure wave is generated by burnt gas and velocity of ascending piston. These pressure waves depend on pressure of burnt gas and the second pressure wave is bigger than the first pressure wave as the increased of load. If pressure waves in the exhaust system are analyzed, the cylinder of normal or abnormal combustion is classified and the misfire cylinder could be detected.

People began to realize the importance if leisure and their interest in leisure activities has been on the increase. Thus diversified study about leisure has been mode.This study is based in the dissertations on teachers' leisure activities and analyzed types if the leisure activities that teachers enjoy (school ranks, actual conditions and atmosphere where teachers work, their mind, space and development if leisure program and so in are analysed.) The summary if the study is as follows.We could notably find the educational sid in relationship between the social position of teachers and leisureThis means most object of our study is focused on young boys and girls(students in junior high and high schools) and their spiritual and physical health is connected with the teachers' leisure activities.The theme analysis of the study is followed and we could find the types if leisure activities, teachers' mind and their participation in leisure.When we see a distribution chart about the dissertations of leisure studies. we could find out that most if them are mode by students in graduate schools of teachers'. especially who were majoring in physical Education.In conclusion the study about teachers' leisure activities has been made since 1980s and the diversified study about it has been increased in 1990sThis tells us that leisure activities are connected with the quality of life as well as teacher are also a group of people who live and work in the society. The study about teachers' social class areas where they live or work, their sex and religion The development of modern industry had brought out drastic changes to human life and it has lead people to enjoy a variety of leisure activities. People began to realize the importance of leisure and their interest in leisure activities has been on the increase. Thus diversified study about leisure has been mode. This study is based on the dissertations on teachers' leisure activities and analyzed types of the leisure activities that teachers enjoy (school ranks, actual conditions and atmosphere where teachers work, their mind, space and development of leisure program and so on are analysed.) The summary of the study is as follows. We could notably find the educational side in relationship between the social position of teachers and leisure This means most object of our study is focused on young boys and girls(students in junior high and high schools) and their spiritual and physical health is connected with the teachers' leisure activities.

부분적으로 Co^2+ 이온으로 치환한 제올라이트 A를 탈수한 후 메탄올을 흡착한 결정구조(a=12.169(1) A)를 입방공간군 Pm3m를 사용하여 단결정 X-선 회절법으로 해석하고 정립화하였다. 이 결정은 360˚C에서 2±10^+Torr 하에서 2일간 진공 탈수한 후 22(1)˚C에서 약 104Torr의 메탄올 증기로 약 1시간동안 흡착시켰다. Full-matrix 최소자승법 정밀화 계산에서 1>3α(1)인 147개의 독립 반사를 사용하여 최종 오차 인자를 R1=0.061, R2=0.062까지 정밀화시켰다. 단위세포당 4개의 Co^2+ 이온과 1.5개의 Na^+ 이온은 6-링 산소와 결합하고 있었다. 4개의 Co^2+ 이온은 0(3)의 (111) 평면에서 큰 동공 쪽으로 약 0.44 (18)A 들어가 위치하고 1.5개의 Na^+ 이온은 0(3) (111)평면에서 소다라이트 동공 깊숙히 약 0.55A 들어간 자리에 이치하고 있다. 단위세포당 약 6.5개의 메탄올 분자가 흡착되었다. 단위세포당 약 6.5개의 메탄올 분자는 큰 동공 내에 위치하였고 4개의 Co^2+ 이온과 2.5개의 Na^+ 이온과 결합하고 있다.. 4개의 산소는 6-링에 위치한 Co^2+ 이온과 결합하고 나머지 2개의 산소는 6-링에 위치한 Na^+ 이온과 결합하고 있다. The crystal structure of a methanol sorption complex of dehydrated partially Co(Ⅱ)-exchanged zeolite A, Co_4Na_4-A 6.5CH_3OH(a=12.169(1) A˚), has been determined by singlecrustal x-ray diffraction techniques in the cubic space group Pm3m at 21(1)℃. Co_4Na_4-A was dehydrated at 360℃ and 2×10^-6 Torr for 2 days, followed by exposure to about 105 Torr of methanol vapor at 22(1)℃ for 1 hr. The structure was refined to fina error indices, R_1=0.061 and R_3=0.060 with 147 reflections, for which Ⅰ > 3σ(Ⅰ). In this structure, four Co^2+ ions and 1.5 Na^+ ions per unit cell lie at 6-ring positions:the Na^+ ions are recessed 0.444(18)A˚ into the sodalite unit and the Co(Ⅱ) ions extend ca. 0.55A˚ into the large cavity. 2.5 Na^+ ions lie in an 8-oxygen ring plane. The 6.5 methanol molecules are sorbed per unit cell. The 6.5 methanol oxygens, all in the large cavity, associate with the 4 Co^2+ ions and 2.5 Na^+ ions in two ways:four oxygens coodinate to 6-ring Co^2+ ions, and two coordinate to 8-ring.

국내 경상북도 포항시 남구에서 채취한 4종의 천연 제올라이트를 화학성분 분석, X-선 회절, 열시차분석 실험, 열중량분석 실험으로 분석하였다. 이들 제올라이트의 주성분은 석영, mordenite, heulandite가 함유된 clinoptilolite이었다. NaOH, Ca(OH)₂, HCI 용액으로 처리한 천연 제올라이트의 성질은 X-선 회절법과 열시차분석 실험법으로 연구하였다. 천연 제올라이트와 화학적으로 처리한 제올라이트, 합성 제올라이트를 이용하여 Cu²+, Cd²+, Hg²+, Pb²+, Cr6+등의 중금속 이온과 알칼리 금속 K- 이온의 제거능력을 비교하였고, 중금속 이온 용액의 pH값과 초기농도, 중금속 이온을 제거하는데 소요되는 반응 시간의 효과 등을 비교하였다. 천연 제올라이트에 Ca²+, Pb²+, and Cu²+ 이온용액을 각각 5ppm첨가한 결과 제거율이 94%, 95%, 97%까지 증가되었다. 또한 0.5N NaOH와 0.5 N HCI 용액으로 처리한 매석산 천연 제올라이트를 이용하여 Hg²+ 이온용액을 5ppm 첨가한 결과 제거율이 약 80% 정도였다. 매석산 천연 제올라이트와 합성 제올라이트 A,X 및 Y가 Hg²+ 이온의 최대 제거율을 나타내었다. The four natural zeolites collected in Pohang, Kyungsang buk-do, Korea, were analyzed by means of wet chemical methods, X-ray diffraction, DTA, and TGA. The results indicate that the primary species of those zeolites are clinoptilolite mixed with quartz, mordenite, and heulandite. These zeolites were treated with NaOH, Ca(OH)₂, and HCI solution and their differences were also studied by X-ray diffraction method and differential thermal analysis method. The capabilities of removing heavy metal ions, such as Cu²+, Cd²+, Hg²+, Pb²+ and Cr6+, and alkaline ion, K+ ions with original zeolites, chemically treated zeolites, and synthetic zeolites were compared. The effect of pH value of solution and initial concentration of heavy metal ions, and the effect of reaction time in removing heavy metal ions were ions were studied. The experimental results showed that up to 94%, 95%, and 97% of Ca²+, Pb²+, and Cu²+ ions could be removed, respectively, out of 5 ppm of untreated natural zeolites. About 80% of the Hg²+ ions could be also removed out of 5 ppm Hg²+ ions solution with Maesuk mt. natural zeolite which was treated with 0.5N NaOH and 0.5 N HCI solution. It was found that Maesuk mt. natrual zeolite was most efficient in removing Hg²+ ions compared with the other natural zeolites studied in this work and synthetic zeolite A, X and Y.

The purpose of this study was to create plan of Green Sport for all in Pusan toward 21st century. The plan of Green Sport for all in Pusan toward 21st century was conducted by theoretical analysis based upon an advanced countries' sport for all state and Pusan's sport for all state. The result of this study are as follows; 1. To set plan for sport for all in Pusan, it should consider the environment of sport for all for citizen's social welfare. It is more important to use the present facilities effectively with the good management than expand sport for all facilities. To set budget for all facilities to expand it is expected from 2002 Pusan Asian Games's profit. 2. The public sport facilities and sport for all facilities should be open for citizen after build sport for all facilities at the near river and sea side. It should give permission to build green sport for all facilities in the zone of protect development. The regulation of entrance fees at the public sport center such as basketball gymnasium, soccer stadium, and baseball stadium. To enter public sport center, it is recommended free for athletes to do competition or exercise and for citizen the lowest fee is recommended during whole year. The officials should be consider very good quality of service for citizen. Also, school's sport facilities are recommended to open for citizen after school off. 3. It is recommended to build one sport center at every district(gu) in Pusan like Sport for all Pusan association (The memorial olympic hall). The olympic park should protect forever, it should not be allowed for other purpose whenever. 4. The government should set budget for labor's sport clubs. Also, the government try to encourage to expand labors' sport facilities in the company as the law promotion for labors' sport. 5. The government and the government of Pusan city should lead every company to keep the law of promotion for labors' sport. Also, the government leads company to promote sport for labors at each company by the reduction of taxation for company such as th incorporation tax and a real estate acquisition tax. For example, the government let them reduce company's tax for company's private sport facilities(center) so give them chance to invest for sport facilities. 6. KOC should keep remain neutral to promote territory's sport, university team in Seoul should get away from the victory oriented idea then they might participate as amateur at the national tournament. 7. To reduce traffic at the center of the Metropolis, the energy saving purpose, the effective using of the center of the Metropolis, and to increase sport for all people, the green sport for all underground facilities are recommended at the foot of Youngdo park and the public elementary, junior, high school's ground without the nature damage. And then it will be help a lot to citizen to stress out and to use effective leisure time for themselves. 8. It was suggested that the green sport for all facilities might build in the sea near the yacht race center at Soo young, Haeundae bathing resort and Kwangan ni bathing resort, with minimizing nature damage. The green cultural resport and ocean sport facilities were recommended at the sea side to play yacht, wind surfing, water ski, and water bicycle for touring and sport for all purpose. 9. The green winter sport resort and sport resort were recommended at Seungji park and Daeshin park for citizen. After build these facilities, it should be open for citizen every day.
