본 연구에서는 SW교육에서 Computational Thinking의 향상을 위한 놀이활동 중심의 UMC(Use-Modify-Create) 전략을 개발하였다. UMC 수업 전략은 학생들이 예제 알고리즘을 분석하고 이를 수정, 확장하여 새로운 SW를 개발하는 모형이다. 먼저 예비교사를 대상으로 1학기 동안 UMC 수업을 적용하였다. UMC전략에 대한 학생들의 self-CT 향상에 대한 t-검사 결과, UMC 수업전략이 CT개념과 실습능력에 도움을 주었다. 또한 Modify 단계와 직접교수식 단계보다 Use단계와 Create 단계의 탐색과 자기주도적 개발과정이 CT능력 향상에 도움을 주고 있음을 알 수 있었다.

This paper proposes directory service protocol in distributed environment. By adding an condition retrieval function to Modify operation, the ExtModify operation improves the inconvenience to transfer a search operation and resume a Modify operation. The method suggests how to correct all the entries which require retrieval condition out of other entries designated by LDAPND.

This study examines teachers' implementation of strategies to modify the aggressive behavior of students with intellectual disabilities in Saudi Arabia, to determine the obstacles to their real-world execution. In addition, it presents potential approaches to overcome the obstacles to implementing strategies with this group of students. The research employed a qualitative design using semi-structured interviews as a data collection tool and applied a thematic analysis. The study population comprised 35 teachers of students with intellectual disabilities and the study sample numbered six teachers. The interviews were conducted via different methods: three by phone, two face-to face, and one using the Zoom platform. The results revealed inadequate understanding among teachers of intellectual disability and behaviour modification strategies, and this affected their capacity to develop plans that were compatible with the needs of students with intellectual disability. The findings also identified multiple obstacles that impede teachers' implementation of strategies to modify aggressive behaviour among students with intellectual disabilities; the most important being the lack of input from a psychological specialist when developing programs to modify aggressive behaviour. In general, it is apparent that programs for modifying aggressive behaviour are neither structured nor complementary, due to the scarcity of administrators with sufficient knowledge and familiarity with the characteristics and personalities of students with intellectual disabilities. This study presents several recommendations, the most important of which is that teachers of students with intellectual disability should develop themselves through training courses to enable them to deal with these students and create treatment plans that include strategies and clear steps to modify the aggressive behaviour of students with intellectual disabilities. To support teachers, it is also necessary to remove the obstacles facing education centres by providing financial support to create an environment in which they can access the required devices and equipment in their classes.

최근 스마트TV의 보급이 급속하게 증가하고 있다. 스마트TV는 표준화된 플랫폼을 기반으로 예약, 교육, 그리고 게임 서비스를 제공할 수 있다. 스마트TV에서 사용자가 요청한 앱을 실행하려면 표준 API를 실행해야 한다. 이때, 스마트TV 플랫폼의 취약점을 분석해서 악성 앱을 실행하거나 사용자가 요청한 컨텐츠를 위조하는 문제가 발생할 수 있다. 그러므로 우리는 확장 API를 수정해서 스마트TV 해킹을 막을 수 있는 방법에 대해 연구하였다. 우리가 제안한 연구 방법을 사용하면, 불법 장치가 스마트TV 장치에 불법적인 접근을 막을 수 있다.

Previous experiments have shown that aqueous sodium silicate ingested in drinking water may modify the gastrointestinal uptake and(or) tissue retention of certain trace elements, including heavy metals. The present experiment tested, with a mineral balance trial using sheep, the hypothesis that dietary silicic acid could modify uptake, retention and(or) biological effects of dietary Cd. Twenty-four wethers were fed a fibrous diet of ground alfalfa hay and cottonseed hulls to which either 0 or 150 ppm Cd was added as $CdCl_2$ and 0, .5 or 1% silicic acid (as dry matter of the diet). Body weight, feed intake, excretion of urine (volume) and feces (weight), digestibility of dry and organic matter, retention of nitrogen, and packed cell volumes of blood were not affected by either Cd or silicic acid (P<.10). Cadmium decreased (P<.05) Ca retention and increased (P<.01) Mg retention. Silicic acid decreased (P<.05) K retention. Silicic acid failed (P<.01) to modify the retention of added dietary Cd. Body retention of K, Mn and Ni in response to silicic acid varied with Cd levels. If Cd is interfering with mineral retention, silicic acid may be effective in preventing this interference.

In this study, fresh state properties and mechanical properties of low slump concrete which is applied to road pavement have been evaluated by mixing modified sulfur. As results, influence of mixing modified sulfur on the workability was low. Also, compressive strength, and flexural strength tend to decrese with increasing addition rate of modified sulfur. However compressive strength, and flexural strength of modified sulfur concrete were equivalent with that of plain concrete.

This paper presents methods using Gaussian normalization for converting pitch contours based on prosodic phrases along with experimental tests on the Korean database of 16 declarative sentences and the first sentences of the story of 'The Three Little Pigs'. We propose a new conversion method using Gaussian normalization to the pitch deviation of pitch contour subtracted by partial declination lines: by using partial declination lines for each accentual phrase of pitch contour, we avoid the problem that a Gaussian normalization using average values and standard deviations of intonational phrase tends to lose individual local variability and thus cannot modify individual characteristics of pitch contour from a source speaker to a target speaker. From the results of the experiments, we show that this slanted Gaussian normalization using these declination lines subtracted from pitch contour of accentual phrases can modify pitch contour more accurately than other methods using Gaussian normalization.

This paper discussed the shape effect of ceramic support carrier in order to facilitate biomass immobilization. The shape of ceramic support carrier was modified hollow pipe type into hollow gear type. After seeding, microorganisms were attached in crevices where protection from shear forces or surfaces where easy to contact with support carrier surface. In case of hollow gear type carrier, initial attachment rate was faster than that of hollow pipe type and obtained thick biofilm. Synthetic wastewater(COD:75~880 mg/L, organic loading rate:0.36~4.22 kgCOD/㎥.d) was treated aerobic fixed bed biofilm reactor where 100% of the volume was filled with the ceramic carrier. COD removal efficiency of reactor filled with gear type support carrier was a little high withing 70 days, and then showed similar removal efficiency. It was found that highly loaded operation with up to 4.22 kgCOD/㎥.d was possible in both reactor. Total biomass amounts of pipe type was higher than gear type, however, attached biomass of gear type was higher than that of pipe type.

본 논문에서는 한정된 에너지를 사용하는 애드 혹 네트워크에서 부분적인 경로 수정을 통해 에너지 사용을 분산함으로써 네트워크의 수명을 증가시키는 Local Path Modify Routing (LPMR) 프로토콜을 제안한다. 애드 혹 네트워크에서 노드의 한정된 에너지는 전체 네트워크 수명에 큰 영향을 끼친다. 따라서 최근 에너지를 효율적으로 사용하기 위한 On-demand 방식의 프로토콜들이 많이 제안되고 있다. 그 중 Power-aware source Routing (PSR)은 에너지의 사용량에 따라 경로를 주기적으로 변경해 줌으로 네트워크의 수명을 늘린다. 하지만 잦은 플러딩으로 인해 라우팅의 오버헤드의 증가와 이 오버헤드로 인한 에너지의 소모가 증가하는 문제점이 있다. 본 논문에서는 에너지의 사용이 많은 노드를 선별하여 각 노드의 주변 노드 정보를 통해 부분적으로 경로를 변경해 줌으로써 잦은 플러딩 없이 경로를 변경함으로 라우팅 오버헤드가 감소하게 된다. 또한 에너지를 많이 소모하는 노드의 에너지를 분산해 줌으로 각 노드들이 에너지를 고르게 사용함으로 네트워크의 수명도 증가하게 된다. 본 논문에서는 NS-2(Network Simulator-2)를 이용하여 LPMR의 성능을 검증한다.
