세계화의 물결은 자본운동의 자유를 극대화시키려는 ‘신자유주의’의 영향을 받아 탈규제화, 유연화, 개방화, 자유화의 특징을 보이고 있다. 신자유주의는 현 시기의 세계자본주의 체제의 가장 중요한 이데올로기적, 정치적 조류를 가리키는 개념으로써 시장적(市場的) 가치만을 절대시 한다. 이는 곧 ‘시민사회 가 활성화되는 속에서 시민사회가 실질적으로 소멸하는 현상’이 생겨남으로써 시민 사회적 전체주의에 이르게 만드는 신자유주의적 파시즘 체제를 일컫는다. (중략)

In this study, we analyzed how the content and achievement criteria of the Geometry domain of Korean elementary school mathematics curriculum have changed. To this end, based on the analysis framework based on the 2015 revised curriculum, the achievement standards for each period were classified into continuous, extinct, and additional types, and their characteristics were examined. In the domain of Geometry, continuous achievement standards accounted for 51% of the total, and there were many achievement standards that remained unchanged in grade and domain. The extinctive achievement standard is 20.4% of the total, and the mathematics contents that were rapidly introduced due to the modernization of mathematics in the 3rd curriculum were eliminated the most from the 4th curriculum, and after the 7th curriculum, With the introduction of staged curriculum and the system of school year group, the contents of learning were either integrated or moved to middle school. The additional achievement standard was 28.6% of the total, and the achievement standard was added the most with the introduction of spatial sensory development in the 7th curriculum. The GAct that the additivel achievement standard is more than the extinction achievement standard in the Geometry domain is the result of the efforts to actively introduce the geometric contents appropriate to the times despite the great flow of curriculum revision of the curriculum reduction. It is hoped that the results of these studies will be used as basic data in the formation of new achievement standards in future curriculum development.

Purpose: The purpose of this study is to report the preliminarily result of the radiologic disappearance of the calcific material, regardless of the size, type or location, on one-time ultrasonographic (US) assisted needling for calcific tendinitis of the shoulder. Materials and Methods: From March to August 2011, 46 patients (47 shoulders) with symptomatic calcific tendinitis were treated by one-time US assisted needling. Initially, a diagnostic US was performed with patient to determine the locations, numbers and sizes of calcific deposits. After 1% lidocaine local anesthesia, the calcific material was punctured with an 18-gauge needle under US monitoring. If no calcific material was aspirated after 2 or 3 additional attempts, the deposits was performed multiple puncture to achieve decompression. And then all patients were performed subacromial corticosteroid injection. All patients were followed up 4 weeks after procedure. To assess the radiologic disappearance after one-time US assisted needling, simple radiographs of the treated shoulder were performed and size, dense, and morphology of the calcific deposits were compared with those in baseline radiographs. For clinical evaluations, visual analogue scale for pain and function (PVAS and FVAS), and American Shoulder and Elbow Surgeons (ASES) score were assessed. Results: There were 11 male and 35 female patients with the mean age of 53.8 years (28-71). The morphology of the calcific deposits were 31 type A and 16 type B by French Arthroscopic Society classification and mean size was $2.9{\pm}6.7$ mm before the procedure. At 4 weeks after the index procedure, the radiographic unchanged group was included in 10 cases and changed group was 37 cases. No intergroup difference for the clinical results after the procedure was evident, but group FAS classification before the procedure was significantly different (p=0.011). Conclusion: At 4 weeks after one-time US assisted needling for calcific tendinitis of the shoulder, the radiographic size- or dense-changed cases were showed in 79%, regardless of the size, type or location of the calcific material. But the radiographic nearly or complete disappearance were showed in only 21%.

During the period of heavy rain from 2002 to 2004, the characteristics of the inflow, temporal and spatial fluctuations of high turbid water according to thermal stratification were studied on the Andong Reservoir which is the largest artificial lake in the Nakdong River basin, Korea. Thermal stratification was formed in June. Its structure determined to the pathway of inflowing turbid water and has affected by the transportation of high turbid water. Regardless of the time and amount of inflow, the high turbid water showed the shape of underflow at the riverine zone, separated from the bottom at the transition zone and moved to the lacustrine zone with the shape of density current. The plunging point depended on the time and amount of inflow. The distributions of thermal stratification and DO concentrations were changed by inflowing discharge. Two thermoclines and minimum DO layers were found out existing at metalimnion in a specific time, respectively. The layer of high turbid water which formed with the thickness of 20 m at the maximum below the depth of 15 m moved toward dam. Not settled to the bottom, the newly formed layer was discharged through the intake-outlet and dispersed into all layers by the circulation in the fall.

Algal growth potential(AGP) assay using Heterosigma akashiwo was conducted in Pukman Bay. The effects of nutrients and microorganisms on the growth of H. akashiwo were specifically evaluated by the algal bioassay method. The different types of growth response of H. akashiwo to the addition of nutrients, and the co-incubation with microorganisms were clearly observed. Before H. akashiwo red tide occurrence, the growth of H. akashiwo was significantly stimulated by addition of nitrate of $50{\mu}M$ with phosphate of $5{\mu}M$. The addition of single phosphate had no clear effect on the growth of H. akashiwo. And the co-incubation with microorganisms had no clear effect on the growth of H. akashiwo. This result indicates that nitrate potentially limited the growth of H. akashiwo before red tide occurrence. However, during a bloom of H. akashiwo, the growth was significantly stimulated by addition of either nitrate of $50{\mu}M$ or phosphate of $5{\mu}M$. The addition of trace metals and vitamin $B_{12}$ had no clear effect on the growth of H. akashiwo in the period. This result indicates that both nitrate and phosphate potentially limited the growth of H. akashiwo during the bloom. On the other hand, during the termination period of H. akashiwo bloom, the growth of H. akashiwo was slightly stimulated by addition of phosphate and nitrate. But the growth of H. akashiwo was significantly enervated by the co-incubation with microorganisms. This result indicates that microorganisms potentially limited the growth of H. akashiwo in the period of bloom termination.

최근 물 사용 및 배분과 관련하여 각종 갈등이 첨예화 되면서 수리권에 대한 체계적인 정리가 필요하게 되었다. 특히, 각종 수리권의 적용 범위나 한계를 논하기 위해서는 근본적으로 하천의 자연유량과 인공유량에 대한 이해가 우선되어야 하는데 이는 수리권의 본질을 이해하는데 기본적인 사항이다. 이를 통해 자연스럽게 '강변수리권'과 '지역수리권', 그리고 또 다른 대표적인 수리권인 '점용수리권'에 대한 비교 검토를 함으로써 수리권에 대한 올바른 인식을 가능하게 하며 이로 인해 물의 합리적이고 효율적 배분에 기여할 수 있다. '강변수리권'은 오로지 강변에 위치한 토지에 필요한 물에 대해서만 적용되는 수리권으로 결과적으로 농업용수에 대한 권리이며 지방자치단체가 아닌 강변 토지 소유자에게 부속되어 있고 하천의 자연유량에만 적용되어 댐 건설로 인해 추가적으로 발생하는 유량에 대해서는 적용하지 않는다. 또한, '강변수리권'은 비록 사용하지 않아도 소멸되지 않으나 한번 소멸되면 회복할 수 없으며 타인에게 양도할 수 없다. 아울러 '강변수리권'끼리는 똑같은 우선권이 있기 때문에 물이 부족한 시기에는 주어진 양을 공유해서 사용하여야 하며 소량이지만 생활용수로 사용코자 하는 경우에는 등록증서가 필요하며 물을 저장해서 다른 시기에 쓰고자 한다면 수리권 허가가 필요하다. '점용수리권'은 "특정 기간동안 특정장소에서 특정한 용도로 특정 수원(水源)으로부터 특정한 양을 취수하는 배타적 권리이다". '점용수리권'은 물의 가용성(availability)을 기초로 하고 있으며 합리적이고 유용한 용도에 사용하는 것을 일반적인 원칙으로 하고 있다. '점용수리권'은 '선점수리권(first in time, first in right)'이라고도 하는데 '강변수리권'과는 다르게 강변에 인접하지 못한 토지소유자가 물을 취수하여 물을 이동시킬 수 있는 권리로 허가없이 증량할 수 없으며 5년간 사용하지 않는 경우에는 소멸된다. '점용수리권'을 얻고자 하는 사람은 장기간 물을 저장하여 사용하고자 하는 '강변수리권자'나 강변에 인접하지 않은 토지에서 지표수나 지하수를 저장하거나 사용하고자 하는 사람들이다. '지역수리권'을 뒷받침하는 사례로 자주 이용되는 미국의 경우에 주(州) 헌법이나 주(州) 수법에 주(州)내의 모든 물은 주(州)의 주민에 속한다고 천명하고 있다. 그러나, 추가적으로 수질관리, 홍수관리, 댐 운영, 재해방지 등 물과 관련한 포괄적인 기능도 주(州)의 책임으로 명시하고 있어 지방정부주(州)가 단지 물의 사용에 대한 권리만 위임받은 것이 아니며 물 관리에 따른 모든 책임까지도 함께 담당하고 있다는 우리나라와 같이 지방자치단체의 물 이용에 대한 권리만 의미하는 '지역수리권'과는 근본적으로 다름을 알 수 있다.

To characterize the initiation, propagation and termination of Cochlodinium polykrikoides blooms in the southeast coastal waters of Korea, 2007, we have analyzed the data set of phytoplankton composition, physical and chemical water properties, and meterological data. The development of C. polykrikoides bloom in 2007 can be summarized in three steps. The first stage from middle of July to end of August was characterized by an unusually persistent and strong southerly wind. C. polykrikoides blooms established already by the strong wind in the middle of south coastal waters were advected intermittently into the study area. Accordingly, highly variable cell densities of C. polykrikoides were observed. At the second stage a favorable growing conditions for C. polykrikoides was developed, which was directed by changes in wind direction from south to northeast and thus enhanced transportation of offshore waters into inshore (August 8 to 30). C. polykrikoides bloom occurred through typical mechanism and showed high cell density. The last stage was represented by disappearance of C. polykrikoides. Typoon 'Nari' carrying heavy rain brought an unfavorable habitat to C. polykrikoides. Low saline condition formed in coastal water due to typoon effects continuously drove the dominant species to diatoms and flagellates which were prevailing over C. polykrikoides in this circumstances(from the middle of September). These stepwise processes could be the causative mechanism of the extraordinarily persistent C. polykrikoides bloom observed in southeast coastal water of Korea, 2007.

The present study was carried out to investigate the temporal and spatial changes in species composition and abundance of polychaetes in Lake Shihwa. Macrobenthic fauna were collected from eight sampling surveys performed in March, June, September and December of 1994, March and October of 1995, February and August of 1996, using a modified van Veen grab with 0.1 $m^2$ coverage area. Polychaete worms, the most abundant macrofaunal group, comprised of 1~22 species at each investigation; number of species continuously decreased during the survey period. The mean density of polychaete was $794{\pm}1,275\;indiv.{\cdot}m^{-2}$ and showed a large fluctuation over time. The variation in abundance was mainly coupled with the domination of Polydora ligni occupying 83% in total density. The next dominant species were Pseudopolydora kempi (mean density of 31 $indiv.{\cdot}m^{-2}$) and Capitella capitata (mean density of 23 $indiv.{\cdot}m^{-2}$). Abundant polychaetes in Lake Shihwa are known to be tolerant to sediment pollution. Ecological indices such as diversity (H') and dominance (D) also indicated that the number of species significantly decreased and a few species predominated in Lake Shihwa after the dike construction. The azoic zone were extended from the upper reach of Lake Shihwa to the vicinity of the dike over time. The reduced number of species, predominance of pollution indicator species and development of an azoic zone reflect severe deterioration of benthic environments in Lake Shihwa.

The cities of Joseon dynasty had weak structure against fire. Fires have resulted in damage on property and life. But they gave a chance to development various policies, planning tools, techniques and facilities for minimizing the damages of fire. This study aims to understand the progression of fire control policy in Joseon dynasty. Fire control policies can be divided into four categories ; fire prevention, prohibition of fire spreading, fire extinguishing and rescue system. The progression of fire control policies can be divided into three steps. In the first step, from Taejong to Moonjong, various policy, such as regal & administrative system, planning tools, fire control works & appliances have been built and executed. In the second step, from Danjong to Hyunjong, fire control work have taken the central place of fire control policy. In the third step, from Sookjong to Sunjong, development of fire control appliances have taken the central place of fire control policy.
