Physics image and interest are factors that influence physics learning. Freshmen enter an engineering college under various learning conditions when they were in high school. Understanding physics image and interest according to characteristics of freshmen will help college physics education. The purpose of this study is to investigate the physics image and interest of freshmen in an engineering college according to their gender and physics course completion in high school and discuss the educational implications of college students on physics learning. The subjects of the study are 664 first grade students in engineering college. We analyzed physics image and interest of students according to gender and physics course completion in high school. Physics image is analyzed using semantic analysis. As a result of the analysis, the physics image is different according to the physics course completion. Interest in Physics depends on gender and physics course completion. Finally, we discuss the educational implications of college physics learning for engineering students.

Purpose: This study purpose to comparison the effects of passive scapular alignment exercise and hold & relaxation technique on craniovertebral angle (C1~C7) with forward head posture due to using variety bag and using computer in healthy subjects. Design: Randomized Controlled Trial. Methods: 22 subjects were divide into two groups: PSAEx group and H/R group two groups. After exercise, the CVA were measured using C7 and tragus. Collected data were statistically analyzed by SPSS 20.2 Results: There were significant differences pre and post the exercise. Conclusion: PSAEx and H/R technique was effective to correct a abnormal CVA posture. The result of this study may helpful as basic data for orthopedic physical therapy.

Purpose : The purpose of this study is to examine the Effect of Lunge Exercise on the Balance of Stable and Unstable Supporting surface. Method : The experimenter was a healthy twenties male and female. The period was two weeks, divided into a stable group and a unstable group. Setting the holding time 4 sec 3 sets of 10 times using the Stable and Unstable Supporting Surfaces. The break time was set at one minute for each set. Balance cushions were used for unstable supporting surfaces. Results : After Lunge Exercise, Both groups had an impact on improving their ability to balance. Conclusion : There has not been much change in the ability to balance the stable and Unstable Supporting Surfaces. However, considering surface conditions, the pre and post exercise comparisons had an effect on improving the ability to balance.

일반적인 게임 콘텐츠에 있어서 수행되는 현실세계에 대한 표현은 물리적으로 연속적이지 않다. 이는 실제 콘텐츠의 이용적인 측면에서 사용자에게 거부감을 유발시키기도 하여 게임의 재미를 반감시키기도 한다. 이 논문에서는 물리엔진을 활용한 실감형 게임콘텐츠의 설계 및 제작을 통해서 실시간적인 오브젝트에 대한 물리현상을 물리엔진을 이용하여 처리하는 기법을 보여준다. 또한, 오브젝트의 물리적인 동작을 제어하기 위해 물리엔진의 설계에 대해서 보여주며 물리엔진과 연동되는 렌더링 엔진 및 그것을 이용한 콘텐츠의 제작에 대해서도 서술한다.

Purpose: The purpose of this study was to investigate the effect of olfactory stimulation on the balance ability of the elderly. Design: Randomized controlled trial. Methods: A total of 20 subjects were randomly assigned to the olfactory stimulation group (2 males and 8 females) and deception olfactory stimulation group (3 males and 7 females). Subjects were subjected to 30 second 3 times olfactory stimulation and deception olfactory stimulation, and the assessment measured pre and post postural distance and postural speed. Results: In the elderly, the olfactory stimulation group was significantly improved the postural distance and postural speed in the eyes closed state than the deception stimulation group (p<.05). Conclusion: As the information is provided through the olfactory stimulation, the postural distance and postural speed are significantly improved. therefore, it is expected that the olfactory stimulation in the elderly will be an effective intervention method to prevent fall.

본 연구는 안정하도 설계를 위해 대상구간으로 원주천 16 km, 20개 횡단면에 대하여 SCAD(Stable Channel Analysis Design)를 이용한 안정하폭 평가를 실시하였다. 안정하폭은 하폭이 증가와 감소로 20%의 허용범위를 적용하였다. 안정하폭의 설계와 물리서식처의 개선을 위해 저수로 폭의 최적 설계를 제시하기 위해 유전자알고리즘을 이용하였다. 물리서식처 개선은 원주천의 하천환경조사와 어류의 군집특성을 이용하여 수중생태계를 대표 할 수 있는 복원 목표어종으로 참갈겨니를 선택하였다. 참갈겨니의 서식적합지수 (HSI, Habitat Suitability Index)를 사용한 서식 적합도 분석은 River2D 모형을 이용하였다. 그에 따라 안정하도 설계와 물리서식처의 개선을 위한 각 단면의 최적 저수로 폭을 제시하였다. 개선된 하천구조에 대한 물리적 교란개선 평가를 실시하였다. 대산구간을 40개 구간으로 분할하여 각 구간의 물리적 교란개선 평가를 수행하여 안정하도 설계와 물리서식처 개선을 위한 하천구조의 개선에 따른 물리적 교란 양상을 평가 분석하였다.

This study aimed at investigating the physics curriculum implemented in science core schools. Thus, the researchers analyzed the science curriculum articulated in the annual reports of science core schools and interviewed some teachers in the schools to identify the features of the physics curriculum. The research findings were as follows: First, with respect to the teaching units by subjects, general science had the largest proportion, as much as 6.7 hours in average, and physics I and II were 4.2 and 4.4 hours, respectively, which were similar to other subjects such as chemistry, life science, and earth science. Second, most of schools opened the courses of physics I and II with two hours for two semesters. Fourteen schools taught physics I as an intensive unit whereas nine schools taught physics II intensively. In the case of specialized subjects, the most frequent one was independent research, and advanced physics was taught in 7 schools whereas physics experiments were done in 34 schools. Based on the findings, this study gives some implications about how to organize the physics curriculum in science core schools according to the 2015 revised science curriculum.

초기 컴퓨터는 주로 원자핵물리와 관련된 계산에 사용되었으나 곧바로 컴퓨터의 도움을 받아 물리 문제를 해결하고자 하는 방법은 물리 전 분야에서 광범위하게 적용되었다. 물질의 가장 작은 요소를 찾고자하는 소립자물리학에서부터, 물질의 성질을 규명하는 응집물질물리, 나아가서 거대 우주의 구조를 밝히고자 하는 우주론에 이르기까지 컴퓨터의 사용이 확장되고 있다. 이러한 확장은 전산물리^[2]라는 물리의 큰 분야를 형성하였고 현재 미국물리학회의 14개 분과 중 하나로 자리 매김하고 있다.^[3]
