Globally, there are environmental problems because of greenhouse gas emissions. The CO₂ emissions rate of the cement industry is very huge, and a continued demand for cement is anticipated. In order to reduce the environmental impact of CO₂ emissions from cement production, this study conducted experiments for the development of non-sintered cement (that has not undergone firing or burning) using granulated ground-blast furnace slag, high-calcium fly ash, and nonactivated hwangto (that has also not undergone firing burning). One experiment used acid resistance and a pH test due to durability, and it conducted a component analysis for the measurement of crystalline analysis and a scanning electron microscope at the mortar. From the experimental results, the mechanical and chemical properties were compared with those of ordinary Portland cement for applicability to construction sites. In the future, to solve the problem through continued research, it will be necessary to reduce cement’s environmental load and involve an economic analysis.

Globally, there are environmental problems due to greenhouse gas emissions. CO₂ emission rates of the cement industry are very large, but the demand for cement will continue in the future. In this study, in order to reduce the environmental impacts of CO₂ emissions from cement production, experiments were carried out for the development of non-sintered cement (i.e. that which has not undergone firing or burning) from granulated ground blast furnace slag, high calcium fly ash, and non-activated hwangto (also not having undergone firing or burning). An experiment was conducted by dry curing and a flow test with fixed water to binder ratio. We observed the mechanical properties for the measurement of flexural· compressive strength by mortar, and tested chemical properties such as water absorption, pH, and carbonation. We compared these mechanical and chemical properties to those of ordinary portland cement applicable to construction sites. In the future, through continued research, this will be expected to reduce the effect of environmental loading and to be economically excellent.

무속신화에 나타난 여성신의 성적 결합과 출산

이창윤(Lee Chang-Yun) 실천민속학회 2006 실천민속학연구 Vol.8 No.-

With sexual point of view, Korean shamanic mythology has narrative procession of ‘sex - sexual intercourse - birth and bring up : the forming of deity’s family line’. But the birth is the most important to the female. Because this biological phenomenon, which is followed by sexual intercourse, performs the mythical purpose of her becoming deity, and becomes the main narrative event in that. But during the process, female body which becomes the object of desire is hidden, and confined by the male. Before and after the birth, the female deity suffers a severe trial. All of these tell us that Korean shamanic mythology reflects a patriarchal or androcentric point of view. Especially, besides female’s suffering, the birth is not realized under immoral sexual intercourse. This reflects the ethical belief of the folk who believe Korean shamanism, and tells that the birth guarantees the legitimacy of deity’s family line. In this paper, we selected twenty nine Korean shamanic myths connected with these matters, analysed narrative procession of ‘sex - sexual intercourse - birth and bring up’, and finally presented the concrete chart of female’s suffering.

본 연구는 새롭게 개발된 느티만가닥버섯의 6개 품종에 대한 형태적, 생리적 특성을 조사하고 endo-, exo-cellular 효소 활성을 측정하기 위해서 수행되었다. 국내 야생종인 Hm3-10과 일본 재배종인 Hm1-1과의 단핵균사 교배를 통하여 343개의 교배 균주를 획득하여 재배를 실시하여 58개 균주를 1차 선발하고 2차로 6개 균주를 선발하였다. 6개 선발 균주를 대상으로 배양 일수 별로 재배를 실시한 결과 배양일수가 80일 이상에서는 재배일수가 19~20일로 단축되어 최적 배양일수를 80일로 결정하였다. 80일 배양일수에서 각 품종별 형태적 특성을 검증한 결과 Hm15-3, Hm15-4, Hm17-5의 3균주가 재배에 적합한 균주로 판명되었다. 각 균주의 endo-cellular 효소 활성도를 측정한 결과, α-amylase의 효소 활성도가 73.9~102,2 unit/㎎ protein으로 가장 높았으며, chitinase 의 효소활성도가 8.1~13.1 unit/㎎ protein으로 측정되었다. Exo-cellular효소 활성도를 측정한 결과, α-amylase의 효소활성도가 5,292~1,184 unit/㎎ protein으로 가장 높았으며, CMCase와 Xylanase의 효소 활성도가 각각 1,140~245 unit/㎎ protein, 94~575 unit/㎎ protein으로 측정되었다. 그러나 β-glucosidase와 chitinase의 활성도는 비교적 낮은 활성도를 나타내었다. This study was carried out to investigate the morphological and physiological characteristics of six new cultivars of Hypsizygus marmoreus (Hm) and measure endo-, exo-cellular enzyme-specific activity. The domestic wild stain (Hm3-10) and commercial strain in Japan (Hm1-1) were mated by crossing monokaryon mycelia. We gained 58 strains from one of 400 crosses through the 1<SUP>st</SUP> cultivation experiment, and selected six strains from one of 58 strains through the 2<SUP>nd</SUP> cultivation experiment. When six of the selected new strains were grown during several spawn culture periods (60, 70, 80, 90, and 100 days), a spawn culture period of more 80 days was considered to be excellent as being shorter than 19~20 days. Therefore, we determined the period of spawn culture as 80 days. Three strains such as Hm15-3, Hm15-4, and Hm17-5 showed an excellent result. When endo-cellular enzyme activity measured eight strains, we obtained a result of that specific activity of α-amylase at the highest as 73.9~102.2 unit/㎎ protein, and chitinase is lower than α-amylase at 8.1~13.1 unit/㎎ protein. When exo-cellular enzyme activity measured eight strains, we determined the result of that specific activity of α-amylase is the highest at 5,292~1,184 unit/㎎ protein, and CMCase and xylanase were 1,140~245 unit/㎎ protein, 94~575 unit/㎎ protein, compared to each other. However, the enzyme activity of β-glucosidase and chitinase is low.

예천전단대 북동부 명호지역 엽리상 화강암류와 압쇄 편마암류에 대한 지구화학 및 Nd-Sr 동위원소 연구

김성원,이창윤,유인창,Kim, Sung-Won,Lee, Chang-Yun,Ryu, In-Chang 대한자원환경지질학회 2008 자원환경지질 Vol.41 No.3

북동 방향의 호남전단대는 한국의 옥천대 남쪽 경계와 선캠브리아기 영남육괴 사이를 지나는 광역적인 우수향 주향 이동 단층대로 동아시아의 두드러진 지나 변형의 방향과 평행하다. 이 논문에서는 호남전단대의 한 지류인 예천전단대 명호지역의 선캠브리아기 압쇄 석영-백운모 편마암과 엽리상 각섬석-흑운모 화강암의 지화학 및 Nd-Sr 동위원소자료를 보고하고자 한다. 엽리상 각섬석-흑운모 화강암류를 $SiO_2$ 대 $Na_2O+K_2O$의 분별도에 도시하면 $SiO_2$의 함량은 61.9-67.lwt% 그리고 $Na_2O+K_2O$의 함량은 5.21-6.99wt%로 화강섬록암 영역에 대부분이 점시된다. 선캠브리아기 압쇄 석영-백운모 편마암은 화강암의 영역에 점시된다. $SiO_2$에 대한 수정된 알칼리-라임 지수 및 Fe#($FeO_{total}/(FeO_{total}+MgO)$)에 의한 관계도에서 엽리상 각섬석-흑운모 화강암류는 캘크-알카리 계열의 마크네슘 성분이 우세한 코딜러리안(Cordilleran)형 중생대 화강암류의 지화학 특징과 잘 부합된다. 또한 이들 암석들은 $Al_2O_3/(CaO+Na_2O+K_2O)$가 $0.89{\sim}1.10$로 중알루미나에서 약한 고알루미나질의 I형에 해당한다 하지만, 원남층의 압쇄 편마암은 $1.11{\sim}1.22$의 과알루미나질을 보여준다. 연구지역 엽리상 각섬석-흑운모 화강암류 및 압쇄 편마암류의 미량원소 성분을 초생맨틀(Primitive mantle) 값으로 규격화한 거미 성분도상에서는 저장력 원소(large ion lithophile element)이며 불호정성 원소인 Rb, Ba, Th 및 U이 부화되어 있고 Ta, Nb, P, Ti 가 상대적으로 다른 원소보다 결핍되어 있으며 이러한 지화학적 특징은 호상형(Arc-type) 화강암류와 전형적인 활동성 대륙연변부의 지각물질로부터 유래한 화강암류와 유사하다. ${\varepsilon}_{Nd}(T)$와 Sr 초생값은 엽리상 각섬석-흑운모 화강암류가 상부지각의 기원물질로부터 형성된 마그마로부터 생성되었음을 지시해 주고 있다. 연구지역을 포함한 영주저반의 엽리상 각섬석-흑운모 화강암류는 전단대에서 멀어지면서 변형에 의한 특정 원소들(Ti, P, Zr, V 및 Y)의 변화경향이 관찰되지 않는다. 이러한 원인으로, 많은 유체를 가지고 있는 엽리상 각섬석-흑운모 화강암류에서는 전단운동 변형동안 전단대 내와 외부의 유체의 흐름에 의한 질량 전달이 동일하게 일어나 암석 내의 부피변화 및 지화학 변질들을 야기 시키지 않았을 것으로 추정된다. The NE-trending Honam shear zone is a broad, dextral strike-slip fault zone between the southern margin of the Okcheon Belt and the Precambrian Yeongnam Massif in South Korea and is parallel to the trend of Sinian deformation that is conspicuous in Far East Asia. In this paper, we report geochemical and isotopic(Sr and Nd) data of mylonitic quartz-muscovite Precambrian gneisses and surrounding foliated hornblende-biotite granitoids near the Myeongho area in the Yecheon Shear Zone, a representative segment of the Honam Shear Zone. Foliated hornblende-biotite granitoids commonly plot in the granodiorite field($SiO_2=61.9-67.1\;wt%$ and $Na_2O+K_2O=5.21-6.99\;wt%$) on $SiO_2$ vs. $Na_2O+K_2O$ discrimination diagram, whereas quartz-muscovite Precambrian orthogneisses plot in the granite field. The foliated hornblende-biotite granitoids are mostly calcic and calc-alkalic and are dominantly magnesian in a modified alkali-lime index(MALI) and Fe# [$=FeO_{total}(FeO_{total}+MgO)$] versus $SiO_2$ diagrams, which correspond with geochemical characteristics of Cordilleran Mesozoic batholiths. The foliated hornblende-biotite granitoids have molar ratios of $Al_2O_3/(CaO+Na_2O+K_2O)$ ranging from 0.89 to 1.10 and are metaluminous to weakly peraluminous, indicating I type. In contrast, Paleoproterozoic orthogneisses have peraluminous compositions, with molar ratios of $Al_2O_3/(CaO+Na_2O+K_2O)$ ranging from 1.11 to 1.22. On trace element spider diagrams normalized to the primitive mantle, the large ion lithophile element(LILE) enrichments(Rb, Ba, Th and U) and negative Ta-Nb-P-Ti anomalies of foliated hornblende-biotite granitoids and mylonitized quartz-muscovite gneisses in the Yecheon Shear Zone are features common to subduction-related granitoids and are also found in granitoids from a crustal source derived from the arc crust of active continental margin. ${\varepsilon}_{Nd}(T)$ and initial Sr-ratio ratios of foliated hornblende-biotite granitoids with suggest the involvement of upper crust-derived melts in granitoid petrogenesis. Foliated hornblende-biotite granitoids in the study area, together with the Yeongju Batholith, show not changing contents of specific elements(Ti, P, Zr, V and Y) from shear zone to the area near the shear zone. These results suggest that no volume changes and geochemical alterations in fluid-rich foliated hornblende-biotite granitoids may occur during deformation, which mass transfer by fluid flow into the shear zone is equal to the mass transfer out of the shear zone.
