학습부진의 순환론적 접근

신재영(Jae Young Shinn) 고려대학교 교육문제연구소 2015 敎育問題硏究 Vol.28 No.3

학습부진에 대한 기존의 이해와 처방은 주로 기능론적 패러다임에 기초하고 있다. 그런데 문제가 발생한 것과 동일한 패러다임 안에서는 현상을 제대로 이해하고 처방하기가 쉽지 않다. 순환론적 접근을 시도해 보면, 대안적 패러다임 속에 이해와 처방의 실마리가 있음을 파악할 수 있다. 대안적 패러다임에서는 학습부진이 학교교육에서 주변부 문제가 아니라 중심부 문제가 된다. 일상에서 학습결손을 예방하는 '양치기식' 교육이 전형적인 수업모형이 되고 이러한 교육의 전형적 사례가 곧 핀란드 교육이다. 순환론적 접근은 대립하는 이념적 패러다임을 단순히 상치 관계가 아니라, 각각의 부작용을 매개로 순환하는 상보적 관계로 파악함으로써 교육문제의 이해와 대안 모색의 지평을 넓히는 모형이 될 수 있다. Previous efforts for understanding and prescribing school underachievement are mostly based on the functionalist point of view. However, it does not seem effective to develop understandings and prescriptions within the same paradigm because its type of schooling itself caused the negative side effect. The cyclic perspective identifies an alternative paradigm that contains appropriate cues for understandings and prescriptions. School underachievement plays the main role rather than 'extra' in the alternative paradigm. The shepherd-style instruction becomes the typical form of schooling in the paradigm by preventing learning-deficit in advance at daily classroom scenes. The Finnish educational system is the exemplar of the case. In addition, the cyclic perspective explains the dynamic relationship between the two incompatible paradigms. Both are in a relationship of complementary circulation rather than confrontation. In the process, the negative side effects that each paradigm inevitably produces plays the role of catalyzer for circulation.

소규모 이산화탄소 주입 실증 부지를 탐색하기 위해 포항분지 영일만 연안에서 취득한 탄성파 탐사와 시추 자료를 분석하였다. 연구지역에서 기반암은 해수면 기준 심도 650~950 m에 분포하며, 상부에 사암과 역암이 우세한 퇴적층이 발달한다. 이 퇴적층은 대부분 포항분지에서 이산화탄소가 초임계 상태로 존재 할 수 있는 심도(약 740 m)보다 깊은 곳에 분포한다. 또한 평균 두께가 123 m로 저장능력이 양호할 것으로 여겨진다. 상부에 올라오는 이암층은 대개 600 m 이상 두껍고 육상과 해상의 포항분지에 광역적으로 분포하고 있어 덮개 능력이 양호할 것이다. 연구지역에 발달하는 북북동 방향의 단층들은 기반암 심도에서 주로 발달하는 퇴적동시성 단층으로 수직 연장성이 불량할 것으로 해석된다. 본 연구를 통해 영일만에 위치한 포항분지 심부에서 소규모 실증에 적합한 저장층과 덮개층이 분포하고 있음을 제시하였다. CO₂ storage site for small-scale demonstration has been investigated in Yeongil Bay, Pohang, SE Korea, using seismic survey and exploration well data. We found a potential storage formation consisting mainly of conglomerate and sandstone. The storage formation unconformably overlies volcanic basement rocks that are located in a depth from 650 to 950 m (below sea level). The depth of the storage formation is suitable for injecting supercritical CO₂ in the Pohang Basin. The average thickness of the storage formation is about 123 m, which possibly provides sufficient capacity at the level of small-scale storage demonstration. The overlying fine-grained deposits consist mainly of marine hemipelagic muds and interlayered turbidite sands. The overlying formation is considered as a good seal rock that is over 600 m thick and widely distributed in the onshore and offshore portions of the basin. NNE-trending faults found in the study area likely formed at basement level, probably not continue to seafloor. Such faults are interpreted as syndepositional faults involved to the basin initiation. This study reveals that the offshore area of the Pohang Basin contains deep geological formations suitable for small-scale CO₂ storage demonstration.

Simulation of CO₂ injection in a small-scale pilot site in the Pohang Basin, Korea: Effect of dissolution rate of chlorite on mineral trapping

Choi, Byoung-Young,Shinn, Young-Jae,Park, Yong-Chan,Park, Jinyoung,Kwon, Yi-Kyun,Kim, Kue-Young Elsevier 2017 International journal of greenhouse gas control Vol.59 No.-

<P><B>Abstract</B></P> <P>In Korea, a small-scale pilot project for CO<SUB>2</SUB> injection was launched to target an offshore reservoir within the Pohang Basin. The objectives of this study are to present the effects of CO<SUB>2</SUB> injection in a sloping aquifer on the evolution of the CO<SUB>2</SUB> plume and its impact on mineral trapping using TOUGHREACT. The results show that the CO<SUB>2</SUB> plume is asymmetrical and rapidly migrates along the slope in the up-dip direction from the injection well. With the migration of the CO<SUB>2</SUB> plume, the increased acidity accelerates the water-rock interactions. As the CO<SUB>2</SUB>-water-rock interactions start quickly due to the rapid spreading of the CO<SUB>2</SUB> plume, the amount of mineral trapping slightly increases due to the precipitation of siderite by chlorite dissolution. However, the stability of siderite is sensitive to the dissolution rate of chlorite. At low chlorite dissolution rates, siderite is more stable than ankerite in an undersaturated state. At high chlorite dissolution rates, ankerite is more stable because of the higher pH. In addition, the amount of mineral trapping increases considerably up to 3.7kg/m<SUP>3</SUP>, which is about 90 times that at the initial rate (0.04kg/m<SUP>3</SUP>). This simulation indicates that the uncertainty in the dissolution rate of chlorite must be considered when estimating the capacity of mineral trapping in situations in which iron-containing carbonate minerals significantly influence the mineral trapping.</P> <P><B>Highlights</B></P> <P> <UL> <LI> The CO<SUB>2</SUB> injection in a small-scale pilot site is simulated to assess mineral trapping by TOUGHREACT. </LI> <LI> The dissolution rate of chlorite affects on the stability of ankerite and siderite, and consequently the amount of mineral trapping. </LI> <LI> The uncertainty in the chlorite dissolution rate must be considered in situations in which iron-containing carbonate minerals. </LI> </UL> </P>

미국의 한국계 청소년들의 종족정체성 형성에 관한 문화기술적 연구

신재영 한국교육학회 1996 敎育學硏究 Vol.35 No.5

본 연구는 미국에 살고 있는 한국이민 2세 청소년들의 사회심리적 적응과정에 관한 일 고찰로서, 주로 그들의 종족정체성 형성과정을 문화기술적 방법을 통해 다루고 있다. 연구지가 된 한인 지역사회의 부모들은 자녀들의 종족정체성 형성 과정으로 "미국화되었다가 되돌아오는" 현상을 종종 보고하고 있는 데, 이는 20세기 초 유럽(영국을 제외한) 이민들의 "flee and return" 현상과 기본적으로 동일한 패턴으로 볼 수 있다. 유럽이민들의 경험에 의하면, 이민 2세대는 적응에 장애가 되는 모국의 흔적들에서 벗어나기 위해 애써 자신의 종족적 배경과 문화적 전통을 회피하는 경향이 있는 반면, 미국화된 부모를 가지고 문화적응에 문제가 없는 3세대는 잃어버린 것들에 애착을 가지고 되찾으려 한다. 이렇게 세대간에 구별되는 적응 행동양식을 역사학자 Hansen은 "아들이 잊고자 하는 것을 손자는 기억하기를 원한다," 혹은 "3세대의 회귀"라는 명제로 표현하였다. 유럽이민의 경험에 비추어 볼 때, 이반과 회귀가 2세대 내에서 이루어지는 한국이민의 경우는 회귀가 촉진되어 일어나는 것으로 파악할 수 있다. 본 연구에서는 두 종족간의 이러한 적응 행동양식의 불일치를 20세기 초와 말이라는 시대적 차이와 더불어, 두 종족이 미국에서 직면하게 되는 사회적 환경의 차이로 설명한다. This study examined the psychosocial adaptive process of adolescents of Korean descent in the United States. The locally identified Korean ethnicity pattern of "flee and return" generally corresponded to the ethnicity pattern of European immigrants, which was formulated during the early 20th century. According to the European experience, the second immigrant generation were eager to evade their ethnic background and cultural heritage, while the third generation cherished it. These generational behaviors were conceptualized by Hansen as "what the son wishes to forget, the grandson wishes to remember," or as "third generation return." In contrast, Korean immigrants showed an accelerated return within the second generation. Beside the chronological difference between the early and late twentieth century, the different social environments which the two ethnic groups encountered in the U.S. were interpreted as being attributable to this discrepancy.

Development of regional uplift and uplift-related strata in Gunsan Basin, Yellow Sea: implications for Cenozoic crustal extension

Lee, Changyoon,Shinn, Young Jae,Ryu, In-Chang Informa UK (TaylorFrancis) 2016 International geology review Vol.58 No.16

<P>The Mesozoic-Cenozoic Gunsan Basin is the northeastern part of the Northern South Yellow Sea Basin between eastern China and the Korean Peninsula. On the basis of seismic interpretation, this study presents and interprets geologic features of regionally uplifted structures, the Haema Arch, located in the central western part of the basin. The Haema Arch is defined as dome-shaped uplift complexes, 95km long and 60km wide. It is characterized by prominent basement uplifts along its margin and plunging syncline inside the arch. The marginal large-scale uplifts are bounded by outward-dipping faults. The uplift-related strata are identified on the hanging wall block of the bounding faults and within the Haema Arch, which can be divided into pre-, syn-, and post-uplift units. The pre-uplift unit rests on the acoustic basement and shows an upturned stratal pattern near the marginal large-scale uplift. The syn-uplift unit locally occurs on the hanging wall block of the bounding faults along the northern and southern margins. The uplift of the Haema Arch and its coeval fault-controlled subsidence possibly occurred during the late Oligocene. The post-uplift unit initially formed on remnant topographic lows during the early Miocene and subsequently covered the overall area of the Haema Arch and the Gunsan Basin. The late Oligocene uplifting of the Haema Arch can be interpreted as an isostatic response to tectonic unloading by the arch-bounding faults that possibly extend to detachment faults. We suggest that the Gunsan Basin underwent crustal thinning and extensional deformation during the late Oligocene, which accounts for the coeval uplifting and fault-controlled subsidence in the study area.</P>
