이 연구에서는 화학 개념학습에서 역할놀이 비유가 대응 관계 이해도 및 대응 오류에 미치는 영향을 비유추론 능력에 따라 조사하였다. 중학교 1학년 학생 151명을 비교 집단과 '원 안에서 달리기' 역할놀이 비유를 사용한 처치 집단으로 배치하였다. 목표 개념인 '기체의 부피와 압력의 관계'에 대한 각 집단별 수업을 진행한 후, 바로 다음 차시에 대응 관계 이해도 검사를 실시하였고, 4주 후에 파지 검사를 실시하였다. 또한, 대표적인 대응 오류를 범한 학생들의 대응 과정을 조사하기 위해 면담을 실시하였다. 연구 결과, 역할 놀이 비유는 학생들의 비유 추론 능력에 관계없이 대응 관계 이해 및 대응 관계 이해 파지를 향상시키는 것으로 나타났다. 대응 오류에서도 역할놀이 비유를 사용한 처치 집단 학생들이 비교 집단 학생들보다 대응 오류의 빈도가 낮았다. 그러나 두 집단의 학생들 모두 유사한 대응 오류를 범하는 것으로 나타났고, 학생들의 비유 추론 능력에 따른 대응 오류 유형별 빈도 차이는 없었다. 이에 대한 교육학적 함의를 논의하였다.

In this study, the effects of concept mapping with feedbacks providing explanatory comments on students' achievement, science learning anxiety, and science learning motivation were investigated in the undergraduate general chemistry course. The aptitude-treatment interactions between students' level of mastery goal orientation and the concept mapping with explanation feedback treatment were also examined. Sixty-seven freshmen from an university of education were assigned to a control group and a treatment group. The tests of mastery goal orientation, science anxiety, and science learning motivation were administered as pretests. For the treatment group, feedback providing students with explanatory comments through whole class discussion was presented after each concept mapping. Whereas the control group students were presented with opportunities solving excercise problems followed by explanation feedback. The intervention was lasted for 10 weeks (30 class periods). After the instructions, a researcher-made achievement test, the science learning anxiety test, and the science learning motivation test were administered. The results indicated that no statistically significant difference was found in students' achievement. In the science learning anxiety, however, the scores of the treatment group was significantly lower than those of the control group. The scores of the treatment group also tended to be higher, though not significant, than those of the control group in the science learning motivation. However, no significant aptitude-treatment interactions were found in all dependent variables.

XPDL(XML Process Definition Language)은 프로세스 정의 교환을 위하여 WfMC에서 제안한 XML 기반 언어이다. 본 논문에서는 워크플로우 프로세스의 정의와 교환을 위하여 XPDL 문서의 구조(Schema)를 UML 다이어그램으로 모델링하여 기업들 간의 상호연동과 협업을 위한 업무흐름 파악을 용이하게 하는 모델을 제안한다. 이를 위해 XPDL 문서를 UML의 클래스 다이어그램과 액티비티 다이어그램으로 변환하는 사상 규칙을 정의하여, XPDL 프로세스 메타모델(Meta-Model)를 구성하는 각 엘리먼트는 클래스 다이어그램으로 모델링하고, 프로세스 액티비티(Process Activity)는 액티비티 다이어그램으로 모델링하는 기법을 제안한다. 또한 제안된 기법을 "신용 카드 상태 체크 시스템"의 워크플로우에 대한 XPDL 문서을 적용하여 제안된 기법의 유효성을 검증한다.

This study was designed to investigate whether applying mind mapping in a biology class had an effect on students' creativity. Participants of this study were 165 1st grade middle school students. The pretest-post test control group design was employed. A control group was instructed with a traditional method and an exerimental group was instructed using the mind-map applied method. The units "Digestion and Circulation" and "Respiration and Excretion" were selected for this study, and each group was treated for 24 class hours. To measure student creativity, the TTCT test was used. For assessing students' level of logical thinking, the compact version of GALT was used. Test results were analyzed by ANCOVA and correlation analysis by SPSS 12.0. The creativity of students in experimental group was significantly improved than the control group (p< .01). Fluency, flexibility, and originality of students in experimental group were improved (p< .01). Students did not show any differences on creativity according to their academic achievement level or gender (p> .05) in the experimental group. Students did not show any differences on creativity according to their logical thinking level (p> .05), either. However, the students of logical thinking level in the experimental group improved their flexibility (p< .05). There was no correlation between students' creativity and their achievement (p> .05), but the creativity shows a lower correlation to performance evaluation (p< .05).

이 연구는 과학 수업에서 의미지도 읽기 전략이 고등학생의 과학 텍스트 읽기 능력에 미치는 영향을 알아보는 것을 목적으로 하였다. 이를 위해 중소도시 소재의 과학중점학교 3학년 학생들(40명)을 대상으로 한 학기 동안 사회과학적 이슈와 화학 개념에 대한 8개의 과학 텍스트를 이용하여 의미지도 읽기 전략 수업을 적용하였다. 의미지도 읽기 전략이 과학 텍스트 읽기 능력에 미치는 영향을 알아보기 위해 학생들이 작성한 사전·사후 과학 읽기 능력 검사를 비교 분석하였다. 분석 결과, 의미지도 수업을 적용한 실험집단의 과학 읽기 능력 검사 점수의 평균이 비교집단보다 유의미하게 높았다. 읽기 과제를 해결하기 전에 의미지도를 그리는 것은 학생들이 텍스트에서 정보를 찾고, 의미를 추론하는 것에 효과가 나타났다. 학생들 역시 의미지도가 텍스트의 내용을 시각화하여 개념들 사이의 관계를 파악하기 쉽고, 자신의 배경지식과 텍스트 내용을 연결시킬 수 있어 텍스트의 이해에 도움이 된다고 인식하고 있음을 알 수 있다.

In this paper, we provide certain fixed point results for a generalized 𝛼-nonexpansive mapping, as well as a new iterative algorithm called SRJ-iteration for approximating the fixed point of this class of mappings in the setting of CAT(0) spaces. Furthermore, we establish strong and ∆-convergence theorem for generalized 𝛼-nonexpansive mapping in CAT(0) space. Finally, we present a numerical example to illustrate our main result and then display the efficiency of the proposed algorithm compared to different iterative algorithms in the literature. Our results obtained in this paper improve, extend and unify results of Abbas et al. [10], Thakur et al. [22] and Piri et al. [19].

In this paper, we study the effects of a deformation mapping on the resulting deformation d/BCK-algebra obtained via such a deformation mapping. Besides providing a method of constructing d-algebras from BCK-algebras, it also highlights the special properties of the standard BCK-algebras of posets as opposed to the properties of the class of divisible d/BCK-algebras which appear to be of interest and which form a new class of d/BCK-algebras insofar as its not having been identified before.

In this paper, we introduce and study a system of nonlinear set-valued implicit variational inclusions (SNSIVI) with relaxed cocoercive mappings in real Banach spaces. By using resolvent operator technique for M-accretive mapping, we construct a new class of iterative algorithms for solving this class of system of set-valued implicit variational inclusions. The convergence of iterative algorithms is proved in q-uniformly smooth Banach spaces. Our results generalize and improve the corresponding results of recent works.

Wellknown invariance of domain theorems are Brower's invariance of domain theorem for continuous mappings defined on a finite dimensional space and Schauder-Leray's invariance of domain theorem for the class of mappings I+C defined on a infinite dimensional Banach space with I the identity and C compact. The two classical invariance of domain theorems were proved by applying the homotopy invariance of Brower's degree and Leray-Schauder's degree respectively. Degree theory for some class of mappings is a useful tool for mapping theorems. And mapping theorems (or surjectivity theorems of mappings) are closely related with invariance of domain theorems for mappings. In[4, 5], Browder and Petryshyn constructed a multi-valued degree theory for A-proper mappings. From this degree Petryshyn [9] obtained some invariance of domain theorems for locally A-proper mappings. Recently Browder [6] has developed a degree theory for demicontinuous mapings of type ( $S_{+}$) from a reflexive Banach space X to its dual $X^{*}$. By applying this degree we obtain some invariance of domain theorems for demicontinuous mappings of type ( $S_{+}$). ( $S_{+}$).

We initiate and introduce the notion of binary soft mapping, which is defined on collection of binary soft sets named as binary soft class over two initial universes U₁ and U₂ with fixed set of parameters. We also define and study the properties of binary soft images and binary soft inverse images of binary soft sets. Examples and counter examples are also given in support of presented properties. Moreover, these concepts are applied to the problem of medical diagnosis in medical expert systems.
