  • A web based courseware was designed and implemented for teaching number 0 to 5 to students of first grade in elementary school. The leveled learning program, according to the difference of learning abilities between learners, provides them with the contents and problems of leveled learning. This study shows the proper feedback to learners after considering their answers and provides them the effective learning situation where children learn without any restrictions of time and space. Therefore, the leveled and differentiated learning has been realized and this courseware enhanced students' interests in learning and desire for achievement. Also, it led them who can attend just for a short time to attend continuously and to participate eagerly in learning.

  • $C^4I$ 체계는 나토군의 효과적인 지휘통제로 정보수집/전파, 지휘결심, 타격명령/실시 등의 제반 절차가 실시간에 이루어지게 되므로 반응시간의 단축을 이루었으며, 정밀유도 무기체계의 유고 핵심시설에 대한 집중 타격은 유고의 군사력을 거의 초토화시킨 상태이다. 코소보 사태와 관련하여 나토군이 선보인 첨단 무기체계 및 신기술은 우리의 국방과학기술의 현주소를 깨닫고 시금석으로 삼을 수 있는 좋은 계기임에 틀림없다. 지금 우리는 기술패권주의 시대에 살고 있고, 이러한 시대에 살아남기 위해서 무엇보다 필요한 것은 최첨단 국방과학기술의 개발일 것이다

  • This study investigated the influences of role-playing analogy upon students' scientific conceptual understandings, application abilities, retentions of conception and application, and learning motivation. Four classes of 7th grade at a middle school in Seoul were assigned to control and treatment groups, and taught about 'motion of molecules' for 4 class hours. For the Treatment group, role-playing analogy instruction was used. The traditional instruction was used for the control group. Data analysis indicated that the scores of the treatment group were significantly higher than those of the control group in the tests on the conception, the retention of application, and the confidence. In the tests of the application, attention, and relevance, there were significant interactions between instruction and student' gender. Both female and male students in the treatment group scored significantly higher than those in the control group in the application test. In the case of attention and relevance tests, male students in the treatment group scored significantly higher than those in the control group. Educational implications are discussed.

  • This study was to investigate factors influencing the school adjustment according to gender and body mass index (BMI) of middle school students who participated in the 2nd-wave Korea Children and Youth Panel Study (KCYPS). This study used a crosssectional design with secondary analysis with KCYPS. The variables were parental interest, behavioral problem, aggression, attention problem, somatic symptom, social withdrawal, depression, and academic achievement. The data were analyzed with descriptive statistics, Pearson's correlation coefficients, and multiple regressions. School adjustment was significantly associated with academic achievement high, explaining 11.3~19.1% of the variance in boys. School adjustment was significantly associated with attention problem, explaining 14.9~42.4% of the variance in girls. Factors influencing school adjustment were significantly different according to gender and BMI. To improve the school adjustment, it is necessary to develop gender-specific school adjustment promotion programs according to BMI.

  • In this study, EEG, HRV, and Vibra image were compared and analyzed in the environmental test room due to stimulation of aroma and color temperature. The condition of the environmental test room was in temperature $25[^{\circ}C]$, relative humidity 50[RH%], air current speed 0.02[m/s] and illuminance 1000[lux] with setting up different sensory stimulation condition which are before exposure, single-sensory stimulation of Jasmine scent, single-sensory stimulation of RED color lighting, and multi-sensory stimulation of Jasmine scent and RED color lighting. The result of this study, at multi-sensory stimulation of Jasmine scent and RED color lighting, relative $S{\alpha}$ wave, SEF50, $SMR/{\theta}$ and SDNN were revitalized, and both sides ${\alpha}$ wave asymmetry index, stress index, fatigue degree, and HRT were decreased. Also, Viba image of tension/anxiety and stress were declined. Therefore multi-sensory stimulation of Jasmine scent and RED color lighting effects to increase the Neuro-energy like amenity, productivity of work efficiency, and concentration.

  • 최근 국내의 해양사고 원인은 인적 오류에 의한 사고가 약 80% 이상으로 제시되고 있다. 이 중 가장 높은 사고 원인은 '경계 소홀'(43.0%)로 전체 사고의 절반에 이르고 있다. 따라서 관제 및 항해 업무에 대한 집중력 향상과 점유적 관리에 대한 연구가 필수적으로 요구된다. 이에 본 논문에서는 선박이 관제 영역 내에 있을 경우 관제사에게 통보하여 관제 집중도를 향상시키고, ASM (Application Specific Message) 서비스와 연계하여 VHF음성통신으로 인한 정보 부재의 취약성을 보완하여, 안전한 항해 및 관제의 효율성을 제공하는 방식을 제안하고자 한다.

  • The goal of this study is to compare entrepreneurial orientation of both countries' students and to compare the effect of individualism on developing entrepreneurial orientation of both countries. In order to achieve this goal, this study will conduct two analysis. Firstly, the comparative study on entrepreneurial orientation of both students will be implemented by conducting F-test and t-test. Secondly, the regression analysis between an independent variable - individualism - and dependent variables - innovativeness, internal locus of control, and entrepreneurial orientation - will be conducted in order to compare the effect of individualism on developing entrepreneurial orientation. Prior to implementation of two analysis, this study has implemented the survey to Korean and Chinese university students to estimate entrepreneurial orientation and a cultural variable to influence entrepreneurial orientation. The question of survey is divided into two parts - individual entrepreneurial orientation including internal locus of control and innovativeness and a cultural variable, individualism. As other precedent comparative studies of Chines and Korean potential entrepreneurship concluded, Chinese students have shown higher entrepreneurial orientation than Korean students. However, on the contrary to prior studies on cultural factors and entrepreneurship, only Chinese students' entrepreneurial orientation is influenced by individualism. Any dependent variables of Korean students were not affected by individualism variable.

  • Background: The causes of ADHD(attention deficit hyperactivity disorder) are various, so it is impossible to understand the whole characteristics of ADHD, only with simple intelligence testing scales. We compared cognitive characteristics of ADHD group with normal controls with Korean Kaufman Assessment Battery for Children(K-ABC). It is well known to evaluate neuropsychological and cognitive aspects of the children. Materials and Methods: Age and sex matched 40 ADHD patients and 40 normal controls tested with the K-ABC. Each subscales compared between pre-treatment patients and controls, pre-treatment and post-treatment in patient group, post-treatment patients and controls. Results: Significant differences are observed in sequential processing, simultaneous processing, cognitive processing and achievement between pre-treatment patients and controls, and in gestalt closure between pre-treatment and post-treatment patients group. But there are no significant differences between pre-treatment patients and controls in gestalt closure and reading/decoding. Conclusions: Methylphenidate improved the scores of simultaneous scale, which means improvement of executive functions such as divided attention, analysis and organization. Methylphenidate also reduced distractibility.

  • 학습 행동에서의 뇌파 측정은 실시간으로 두뇌 기능 상태를 연구하는데 유용한 연구 방법이며 대뇌의 부위 중 전두엽은 새로움에 대한 지향 반응과 사고 활동에 중요한 역할을 한다. 본 연구에서는 중학교 2학년 학생에게 새로운 시청각 학습 자료를 제시하고 5회의 반복학습이 이루어지는 과정에서의 전두부($Fp_2,Fp_2$)의 뇌파를 측정하고 Fourier, Wavelet 변환을 하여 정량적으로 분석하였다. 주의 집중, 정서 등 인지와 관련지어 특정파의 조절 능력 및 파의 특성을 이용한 여러 연구들을 종합해보면, 기억력, 주의지속과 연관되어 알파파, 베타파와 세타파가 발생되는 것을 볼 수 있다. 이 중 알파파는 기존의 뇌 상태를 동기화시키고 주의나 기억의 과정에 영향을 미칠 수 있는 것으로 증명되었다. 본 논문에서는 신호 처리에 높은 효율을 보이는 Wavelet 변환을 이용하여, 학습이 됨에 따라 변화하는 EEG 신호 가운데 알파파의 패턴과 활성도를 분석하고자 한다.
