In this paper, a teaching unit on series of number sentences with patterns is designed according to Wittmann's perspectives. In this paper, series of number sentences wish patterns means number sentences in which some patterns are contained. especially, seven kinds of number sentences wish patterns are offered as basic materials, and fifteen tasks based on these basic materials are offered. These tasks are for ninth grade students and higher grade students. These tasks heap students to recognize patterns, and to understand mechanism underlying in those patterns by looking for patterns and proving whether these patterns are generally hold. As working on these tasks, students can reinforce meaning of algebraic expression, its manipulation, and concept of number series. Students also can reinforce mathematical thinking such as analogical thinking, deductive thinking, etc. In this point, this teaching unit reveal important objectives, contents, and Principles of mathematics education. This teaching unit can also be rich sources for student's activities. Especially, for each task's level is different, each student's personal ability is considered fully. Since teachers can know mathematical facet, psychological facet, and didactical facet holistically, this teaching unit can offer broad possibilities for experimental studies. SD, this leaching unit can be said to be substantial. In this paper, this leaching unit is not applied in classroom directly. Actually such applying in classroom is suggested as follow-up studies. By appling this teaching unit in various classroom, some effective informations for teaching this teaching unit and some particular phenomenons in those teaching processes can be identified, and this teaching unit can be revised to be better one.

Purpose: To analyze the job of nursing unit managers working at women's hospital, using DACUM (developing a curriculum), DACUM is a method for analyzing job-focused competency. Methods: This study involved a descriptive survey. A DACUM workshop was held to define women's hospital nursing unit managers' role and identify their duties and tasks. For the workshop, a committee was formed consisting of 5 women's hospital nursing unit managers. Finally, after validation, the developed contents were made into a survey asking about nursing unit manager's duties and tasks. Results: Sixteen duties and 83 tasks were identified on the DACUM chart. The importance, difficulty, and frequency of the tasks were ranked in terms of A, B, and C, with A being the highest degree. Eight tasks received A's all in importance, difficulty, and frequency of performance. The 8 tasks were: 'taking over', 'taking care of seriously ill patients on handover', 'ward rounding', 'analyzing and resolving demands identified during handover and patient tour', 'reporting patient status during rounding', 'promoting breast-feeding', 'uterine contraction, and training for breast-feeding'. The duty with the biggest determinant coefficient (DC) was 'patients complaint management' (DC=7.09). Based on tasks, the one with the biggest DC was 'solving patient and patient guardian's complaints' (DC=7.53), followed by 'making infection control guidelines' (DC=7.5). Conclusion: When expanding the nursing staff of the hospital, women's hospitals nursing unit managers also need to use administrative functions as intermediaries to focus on the operation management of the entire hospital rather than direct nursing to suit their role.

This study investigated whether there are differences between Korean-English bilingual and Korean monolingual children on phonological awareness skills. Participants were 11 Korean-English bilingual children and 12 Korean monolingual children. The children's ages ranged between 6 and 7 years. The results were as follows. First, the bilingual children significantly outperformed monolingual children on overall phonological awareness tasks. The bilinguals performed significantly higher than monolinguals on all three types of phonological awareness tasks (segmentation, deletion, and blending). Second, there was a significant difference between the groups with respect to phonological units of the tasks. The bilinguals performed significantly better than monolinguals on the phonemic unit tasks, but two groups did not differ significantly on syllabic unit tasks. There was an interaction effect between unit size(syllables and phonemes) and group (bilinguals and monolinguals). Third, there were correlations for both bilingual and monolingual children between overall phonological awareness skills and word recognition skills.

This study deals with the motion modeling by the unit motion of robots and the work measurement through classification of robot motions and standardization. The proposed approach is to scrutinize the Predetermined Time Standards(PTS) methods for measurement of manual tasks performed by people and the basic motions for accomplishing that tasks. And then, it constructs the unit motion models as subsets composed with the basic motions. It apply together with movements distance as a time variable, too. These results are used for the work measurements of robots by the unit motion models.

In this paper, we propose a theoretical framework for Chinese high school mathematics teachers use new textbooks based on the work of Remillard (1999) and Chau (2014). Based on this framework, a multiple case approach was used to investigate how two high school mathematics teachers from Shanghai use new textbooks. The results suggest that in the curriculum mapping arena, both the novice teacher and the expert teacher often planned to appropriate the unit content, and sometimes planned to add supplemental content. When organizing the unit content, novice teacher always planned to follow the new textbook in sequence, while expert teacher often would follow the new textbook in sequence, but sometimes planned to rearrange the unit content. In the design arena, both the novice teacher and the expert teacher tended to appropriate the introduced tasks and definitions. The novice teacher often planned to appropriate the example problems and exercise problems, while the expert teacher often intended to flexibly use the example problems and exercise problems. In the construction arena, the novice teacher seldom adjusted the planned tasks; in contrast, the expert teacher adjusted the planned tasks more frequently. In the reflection arena, the novice teacher often thought she should improve the mathematics tasks, while the expert teacher almost always thought he needed to improve the mathematics tasks. The framework shown in this paper provides a tool to investigate how mathematics teachers use textbooks.

이 연구의 목적은 지방자치단체에서 사용하고 있는 단위과제 현황, 단위과제 운영 및 기록관리 관점의 문제점을 조사 및 분석하여 그 과정에서 도출된 시사점들을 기반으로 텍스트 기반 빅데이터 기술을 활용하여 문제점에 대한 개선방안을 제시하는 것이다. 지방자치단체는 단위과제의 오분류로 인한 보존기간 책정 오류, 과공통사무와 기관공통사무의 유형식별 불가, 단위과제의 과대·과소·중복생성의 오류, 단위과제 명칭의 오류, 참고 가능한 표준의 부재, 통제 가능한 시스템 또는 도구의 부재 등으로 인해 기록관리 운영상 심각한 상태에 놓여 있다. 그러나 단위과제의 수가 약 72만개로 지나치게 많은 수량 때문에 효과적으로 통제할 수 없는 실정이며, 따라서 엄밀하고 통제할 수 있는 도구 및 표준이 필요하다. 본 연구에서는 이와 같은 문제점을 해결하기 위하여 빅데이터 분석 기술 중 텍스트기반 분석 도구인 코퍼스와 토큰화 기술을 적용한 시스템을 개발하고, 이를 기록관리기준표를 구성하고 있는 명칭 및 구성용어에 적용하였다. 이러한 단위과제 운영 지원도구는 통일성 있는 보존 기간 책정, 위임사무 기록물 식별, 중복·유사단위과제 생성 통제, 공통 과제의 표준적인 운영 등을 지원할 수 있는 도구가 될 수 있어 기록관리 업무에 상당한 기여를 할 수 있을 것으로 예상된다. 따라서 향후 빅데이터 분석 방법론을 활용한 지원도구가 BRM 및 RMS 등과 연계할 수 있다면 기록관리기준표 관리 업무의 품질이 높아질 수 있을 것으로 보인다.

The purpose of this study was to examine and analyze the cognitive demand of the mathematical tasks suggested in the middle school textbooks. In particular, it aimed to reveal the overall picture of the level of cognitive demand of the mathematical tasks in the strand of geometry in the textbooks. We adopted the framework for mathematical task analysis suggested by Stein & Smith(1998) and analyzed the mathematical tasks accordingly. The findings from the analysis showed that 95 percent of the mathematical tasks were at high level and the rest at low level in terms of cognitive demand. Most of the mathematical tasks in the textbooks were algorithmic and focused on producing correct answers by using procedures. In particular, the high level tasks were presented at the end of each chapter or unit for wrap up rather than as key resources.

The purpose of this study was to analyze the weight measurement tasks according to children's ages and whether 4-to 6-year-old children use proper measurement equipment to measure weight. The study subjects were 105 preschool children: 37,38, and 30 4-, 5-, and 6-year-old children, respectively. The results showed that young children use 3 to 4 strategies. They used a strategy to estimate objects visually on the first step in measurement by direct comparison. On the second step, in measurement by nonstandard unit, they held up objects with one hand or two hands. That is, two strategies were shown in measuring objects with hands in this second step. On the third step, which is measured by standard unit, they used a strategy to choose the equal arm balance out of suggested measurement equipment.
