  • 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.

  • Purpose: This study was conducted to analyze the concept of nurses' emotional labor. Method: Rodgers's evolutionary concept analysis was used. Result: Nurses' emotional labor can be defined by two attributes: emotional distortion and self-regulation process. Antecedents of nurses' emotional labor include interactional, organizational and personal factors. The consequences of nurses' emotional labor are emotional dissonance and internalization of organizational display rules. Conclusion: Appropriate instrument to operationalize the concept need to be developed.

  • Purpose : The concept of organizational socialization has been regarded as an abstract concept of organizational learning process and it has been used as strategy for the organizational goal attainment. New graduated nurses' organizational socialization has been a very important process for learning knowledge, skills and behaviors in hospital setting. This study was to analyze and clarify the meaning of the concept of Organizational Socialization. Method : This study use the process of Walker & Avant's concept analysis. Results : The critical attributes of organizational socialization were identified as : 1) Internalization of Value and belief of organization; 2) Learning of organizational rules and modes of living; 3) Improvement of job performance; 4) Maintenance of supportive relationship; 5) Formation of occupational identity. The antecedents of organizational socialization consist of those facts that 1) negative feeling of role; 2) difficulties of interpersonal relationship; 3) unskilled work performance. And the consequences of organizational socialization consist of those facts that 1) organizational commitment; 2) job satisfaction; 3) intention of leave work setting; 4) improvement of job performance; 5) improvement of decision making; 6) maintenance of supportive relationship. Conclusion : Through this concept analysis, the concept of organizational socialization is defined as internalization of value and belief of organization, learning of organizational rules and modes of living, improvement of job performance, maintenance of supportive relationship and formation of occupational identity.

  • The purpose of this study is to investigate the degree of concept understanding on the stratum for elementary school students. For this objective, questions on the stratum concept were developed, and concept survey was conducted for random sampling of $5^{th}$ and $6^{th}$ grade 536 students. As a result, students chosen correct answers of the average 57.4% for 16 questions. Below the average rate of correct answers in each domain were 1 question in the definition of the stratum, 3 questions in formation of the stratum, and 4 questions in features of the stratum. Especially, the percentage of correct answers were appeared in lowly that the difference between the visible side and non visible side on the stratum, the definition and formation process of a fault and the main cause of the stratum's exposure. Also, between the residence, grade, and gender of students, there were significant differences in 2 questions, 7 questions, and 1 questions, respectively. Therefore, many elementary school students do not have high understanding about the stratum concept. Through the results of this study, it can be contributed to find an efficient ways as a basic data for modify misconceptions of the stratum to the scientific concept.

  • This work describes a derivation process of JIC(Joint Integrating Concept) based JFC(Joint Functional Concept) analysis of an Aegis BMD(Ballistic Missile Defense). JIC is developed through JOC(Joint Operating Concept) and JFC based on capstone strategy and concept. Aegis BMD is a sea-based ballistic missile defense to detect ballistic missile threat, increase engagement battlespace and enable multiple engagement based on Aegis ships. Aegis BMD is a good case of JIC due to performing an Joint operations based on System of Systems under highly complicated NCW environment. This work analyses JFC using QFD(Quality Function Deployment) and UJTL(Universal Joint Task List). From this analysis the JIC of Aegis Korean BMD is derived using a CASE tool.

  • We propose a multi-strategic concept-spotting approach for robust spoken language understanding of conversational Korean in a hostile recognition environment such as in-car navigation and telebanking services. Our concept-spotting method adopts a partial semantic understanding strategy within a given specific domain since the method tries to directly extract predefined meaning representation slot values from spoken language inputs. In spite of partial understanding, we can efficiently acquire the necessary information to compose interesting applications because the meaning representation slots are properly designed for specific domain-oriented understanding tasks. We also propose a multi-strategic method based on this concept-spotting approach such as a voting method. We present experiments conducted to verify the feasibility of these methods using a variety of spoken Korean data.

  • 과학 개념에 대한 높은 이해와 과학 분야에 무한한 가능성과 잠재력을 가지고 있는 과학영재들이 물리 개념 이해 과정 중에 나타내는 사고 모형을 분석하기 위해서 역학 개념 검사인 FCI, MBT와 전자기학 개념검사인 CSEM을 사용하였다. 세 가지의 설문지 필답검사를 실시한 후에는 그룹 토의의 교실 상황 관찰과 개인 면담을 실시하고 그 결과를 종합 분석하였다. 분석 결과에 따르면 과학영재의 물리 개념 이해 과정에서 나타나는 사고 모형은 물리 개념에 대한 정확한 이해와 적용으로 개념의 형성이 안정성과 일관성을 보이는 일관성 사고 모형을 가진 학생과 문제에 적용할 때마다 유동성과 상황 의존성을 보이는 다양성 사고 모형을 가진 학생으로 분류되었고 또한 과학영재이지만 뉴턴의 운동 법칙에 대하여 힘과 운동의 관계를 잘못 이해한 아리스토텔레스 정신모형을 가진 학생과 옳은 과학 개념인 뉴턴 모형을 가진 학생 그리고 문제 상황에 따라 달라지는 두 정신모형이 혼합된 학생으로 분류되어 개인차가 있음을 알 수 있었다.

  • 최근 문헌정보학 분야에서 고객이라는 용어가 자주 쓰이기 시작하였으나. 기존의 용어인 이용자와 그 의미가 뚜렷이 구분되지 않고 있으며, 또한 도서관 현상에서는 고객이라는 용어에 대한 거부감도 나타나고 있다. 이에 따라 본 고에서는 고객이라는 용어의 의미를 관련 용어와 비교하여 고찰하고, 이러한 개념이 도서관 및 정보센터의 경영에 어떠한 의의를 가지는지를 논의하였다. 도서관은 고객 개념을 도입함으로써 경영에 마케팅관점을 적용하고 있으며, 이러한 활동은 도서관 경영 전반에 걸친 변화를 요구하고 있다.

  • 이 연구에서는 제7차 중학교 3학년 과학 교과서에서 원자 및 분자 개념을 표상한 시각자료의 유형 을 조사하고, 그 해석 과정을 기호학적 관점에서 분석했다. 원자 및 분자 개념은 구 도식, 일상생활의 사물, 공 과 막대기, STM 그래픽 등으로 다양하게 표현되고 있었다. 모형의 조작 가능성 여부를 기준으로 원자 및 분 자 개념을 이미지로 표상한 시각자료와 사물을 이용하여 원자 및 분자 개념을 표상한 시각자료를 구분했다. 이 시각자료들을 해석하기 위해 필요한 과정을 구조화 과정과 번역 과정을 포함하는 기호학적 모델을 이용하여 체계적으로 분석했다. 원자 및 분자 개념을 표상한 시각자료를 해석하는 것은 여러 단계의 해석 작업을 필요 로 하는 복잡한 과정이었다. 이에 대한 교육적 함의를 논의했다.
