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. The theme analysis of the study is followed and we could find the types of 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 of 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 1990s. This 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 leisure will be more specialized and we expect the more subdivided study about teachers' social class areas where they live or work, their sex and religion.

        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.

        Drosophila stuvarista(sta) gene encodes the ribosomal protein D-p40, consisting of 270 amino acids. The D-p40 is highly conserved between such evolutionarily distinct organisms as human(63% identity) and hydra(58% identity) and has the effect of Minute phenotype such as other ribosomal proteins. We identified the sta gene in the process of Drosophila cDNA library screening and analyzed the developmental expression pattern of sta gene in the transcription level using in situ hybridization. Each animal stage and tissues of 3rd instar larva and adults were showed ubiquitously expression pattern. These results were similar to other ribosomal proteins that represented Minute phenotype. Also, we expressed the 31kDa recombinant proteins of D-p40 using his-tag expression system in E. coli and purified by affinity chromatography. Immunoblot result of the developmental stages was showedthat strongly detection only the stage of embryo and pupa. This result suggested that the expression of sta gene were regulated in the level of post-translation modification ailed considered that sta gene had to other function during development as well as to function as a core ribosomal component.

      • 포항산 천연 제올라이트와 합성 제올라이트에 의한 금속 이온의 제거

        박상윤,장세복,김덕수,김양 濟州大學校 基礎科學硏究所 1996 基礎科學硏究 Vol.9 No.2

        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.

        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.
