This study shows the weathering characteristics of mica-schist affected by faulting and metamorphism through laboratory tests. Frozen-thaw test, which simulate the physical-chemical weathering processes in the laboratory, shows the important influence of foliation developed in mica-schist, resulting in $20{\sim}40%$ reduction of UCS according to weathering grade of rock. Slaking durability test was carried out for different weathering grade rock specimens and indicated that the specimens from fault area had a low durability index compared to other relatively fresh samples. XRD analysis allowed to estimate the dynamic evolution of mineral composition through wet-dry cycle in which the chlorite was the most important mineral leached out during slaking test. The creep test indicated that the main deformation produced along the foliation plane. The compacted clay minerals between discontinuity planes influence on the discontinuity shearing properties and result in a big difference between peak shear strength and residual strength. The results of laboratory tests on mica-schist show the possibility of a important deformation along the foliation plane or discontinuity.

서평논문 : 현대 러시아의 사회계급,계층 구조: 이론과 현실
최우익 ( Woo Ik Choi(чой Ву Ик) ) 서울대학교 러시아연구소 2015 러시아연구 Vol.25 No.2
Данная статья ставит целью ознакомить читателей с книгой российского социолога Н. Е. Тихоновой ≪Социальная структура России: теории и реаль- ность≫. Монография объединяет несколько концепций структуры и стратифи- кации российского общества, а также анализирует российскую социальную реальность. По мнению автора, россияне считают, что в реальном российском обществе больше всего представителей низших слоев. Анализ Индекса уровня жизни показывает, что в России примерно 40% обеспеченных людей, в то время как малообеспеченное население составляет 60%. Следуя неомарксисит- скому подходу, 81% россиян является эксплуатируемым классом, а с позиции неовеберианского подхода 60% россиян не имеют права голоса. Таким образом, более 60% россиян пассивны и находятся за чертой бедности. Ресурсный подход показывает, что в российском обществе можно выделить класс исполнителей, класс капиталистов и третий класс. Представители третьего класса, занимая центральное место в структуре российского общества, как раз и являются реальным средним классом. Можно заключить, что применение ресурсной методологии помогает Н. Е. Тихоновой ярче выявить факторы классовой структуры российского общества, рассмотреть, как развивался каждый класс в отдельности, и как складывались межклассовые связи.

러시아 중앙연방관구 주민의 시장개혁기 사회ㆍ경제적 변화와 특성
최우익(Choi, Woo-Ik) 동북아시아문화학회 2013 동북아 문화연구 Vol.1 No.35
This study focuses on socio-economic changes and characteristics of the residents of the C entral Federal District of Russia. Actually the Central Federal District, which includes Moscow, is the center of Russia. Therefore, the study about residents of the Central Federal District shows how changes occur in Russia and Russian people"s lives and what features they have. The residents of the Central Federal District are classified into two directly-opposed groups in aspect of the phenomenon of population and migration, employment and economic activity, income and social stratification. In other words, the residents of the Moscow City and Moscow region are in pretty good socio-economic conditions, but the residents of the other regions are in poor conditions. However, there are very serious social stratification phenomenon in the former. Under these circumstances, equalized regional development and income distribution are some of the most important challenges of the market economy in Russia.

This study examines how the social consciousness of Russians changes over 20 years since the start of economic reforms. For this purpose, the study used data of Rosstat and social surveys by the Levada Center, as well as materials of different organizations and scientists. 20 years passed after the start of economic reforms, but not more than half of Russians approve of these reforms. In addition, the rate of citizens who believe that the success achieved by the reforms is not more than 10%. On the other hand, the rate of people who believe that their status is lower than middle class is 80%. In such a social consciousness it is difficult to create a good social atmosphere. But Russian citizens show a passive position, without taking part in mass demonstrations and rallies. Nevertheless more than half of the population is experiencing social pressure, and increases the percentage of citizens who believe that this tension will take the form of public protest. 본 연구는 경제개혁이 시작된 지 20여 년이 흐르는 동안 러시아인의 사회의식이 과연 어떻게 변화하였는지 살펴보고 있다. 이를 위해 본 연구는 러시아 통계청 자료와 레바다 센터(Левада-Центр)의 설문조사 자료, 그리고 그 밖에도 다양한 기관 및 학자들의 의식조사 자료를 이용하고 있다. 경제개혁이 시작된 지 20여 년이 지난 현재, 개혁에 대한 러시아 국민의 지지율은 절반을 넘지 못하는 실정이다. 게다가 개혁 과정에서 자신이 성공을 거두었다고 생각하는 국민 비율은 10% 수준에 불과하다. 반면 자신을 중간층 이하로 인식하는 비율은 80%에 달하고 있다. 이러한 사회의식 속에서 양호한 사회적 분위기가 조성되기는 힘들다. 그러면서도 러시아 국민은 대중적 시위나 집회에 섣불리 참여하지 않고 소극적 태도를 보이고 있다. 하지만 사회적 긴장감을 느끼는 국민이 절반 이상이며, 그 긴장이 사회적 저항 형태로 표출될 것으로 여기는 국민의 비율도 높아지고 있다.

인공풍화가속실험을 통한 울릉도에 분포하는 화산암의 풍화특성 고찰
우익 ( Ik Woo ) 대한지질공학회 2015 지질공학 Vol.25 No.4
Artificial accelerated weathering test evaluated rocks from near the circuit road of Ulleungdo island, approximately 120 km from east of the Korean Peninsula. The tests subjected rock specimens to conditions based on the climate of the island. The specimens (such as basaltic breccia, trachyte, volcanic breccia) were preliminarily classified using a TAS diagram (XRF data) and based on the constituent minerals (XRD data); they were further classified by weathering degree according to their absorption ratios. During the artificial accelerated weathering, the absorption ratio of most of the specimens increased, but the point-load strength did not decrease in most cases, except for the volcanic breccia. The greater initial absorption ratio of trachyte rock specimen in comparison withthe other specimens led to a greater increase of its absorption ratio during the artificial accelerated weathering test. The volcanic breccia specimens showed the greatest increase of absorption ratio and the biggest reduction ratio of the point- load strength during the tests. These results could aid prediction of the weathering rate of rocks in Ulleungdo island subjected to weathering processes; trachyte which appears to accelerate with time, and volcanic breccia whose mechanical strength can largely decrease in a relative short period of time. Proper measures therefore appear necessary for the prevention of natural disaster such as rock fall and landslide around the circuit road.
