We have developed a new torque magnetometric method for measuring the M-H hysteresis loop of a spheroid-shape magnetic material having a uniaxial anisotropy. Our torque magnetometric method gives the saturation magnetization as well as the remnant magnetization, simultaneously. A torque magnetometer having the torque sensitivity of $10^{-6}$ dyn cm could give the extreamly high sensitivity of $10^{-9}$ emu in measuring the magnetic moment, which is high enough to measure the magnetic moment of a monolayer Ni film. The accuracy of the present method was negligibly affected even at the applied fields near the coercivity where magnetization was inhomogeneous.

If virtual reality is well known through the medias, it seems that a few visual concepts are clearly related to VR. We try to think about it and introduce to a philosophy of VR techniques. So, from techniques and media techno-powers promotional campaigns, we aim to areal technology, it means an objective reflection on the VR techniques. To do so, we study the representations of VR in films. And we conclude that a negative image is the most common representation, related, often, to an Orwellian vision of the future world. In the second part, we study some VR films, and especially some made by famous film directors (Iñárritu, Bigelow). 'Head-turn' and 'Walk-around' films are commented to check their limits. Finally, we consider that for the moment, VR remains only a new space to screen films (into VR platforms connected to the Internet).

Purpose: The purpose of this study was to evaluate whether a relationship exists between head posture and phoria, and usefulness in examining habitual head posture. Methods: Twenty two subjects (20 males and 2 females, mean age $23.6{\pm}2.7$ years) with abnormal phoria from participants randomized were enrolled in this study. For all subjects, testing included case history, cover test, refraction, phoria and vergence test. Habitual head posture (head posture, head tilt and face turn) was measured by Impression IST, and observed by examiners. Results: The abnormal head posture was revealed in some subjects with abnormal phoria. Spearman' correlation ($\rho$=0.524, p=0.045) showed significant correction between face turn and phoria at distance in 15 subjects with prism prescription. No significant relationship between head posture and phoria was found in subjects with abnormal phoria. The objective measurement and subjective observation of head posture showed insignificant correction but there was a distinct difference. The former was detail and the latter was discriminate. Conclusions: Presence of abnormal head posture was found in phoric subjects. The results indicate the need to observe habitual head posture at all major positions of gaze in phoria.

본 논문에서는 중요한 목뼈 부문의 움직임을 다루도록 한다. 특히, 목뼈의 가쪽 굽힘과 돌림에 대한 각도를 측정하고 고통을 수반하는지를 파악한다. 측정한 각도가 정상수치를 크게 벗어나거나 통증을 동반하면 이상이 있는 것으로 간주하여 치료법을 제시한다.

The purpose of this study was to investigate the relationship between vertical jump and lower extremity muscle strength of elementary school baseball players. This study subjects were conducted with a total of 40 subjects. Vertical jump was measured using a vertical jump gauge, and a hand held dynamometer was used to measure lower extremity muscle strength. For the measurement of lower extremity muscle strength, flexion·extension·adduction·abduction·internal rotaiton·external rotation of both hip joint, flexion·extension of both knee joint, dorsi flexion·plantar flexion of both ankle joint were measured. pearson's correlation analysis was used to analyze the correlation between vertical jump and lower extremity muscle strength. From these results, it was found that the stronger the leg muscles except for the plantar flexion, the higher the vertical jump was, indicating a positive correlation. In future studies, follow-up studies on the relationship between batting ability and vertical jump & lower extremity muscle strength are needed.

우리나라 수박재배에서 가장 큰 문제가 되는 병해는 덩굴쪼김병(만할병), 덩굴마름병(만고병), 탄저병, 역병(돌림병)이라 할 수 있다. 이외에 5$\~$6가지의 병이 발생하고 있으나 상기 4가지 병해에 비하면 발생면적도 적고 피해도 일반적이지 못하다. 덩굴쪼김병은 접목재배에 의하여 피해가 경감되고 있으나 수박재배 경험이 풍부하지 못한 농민들은 이 병해 때문에 실패하기 쉽다. 덩굴마름병은 특히 시설재배에서 피해가 큰데, 전생육기간동안 기온이 낮을 때 발생하므로 해마다 농민들이 골치를 앓는 병해다. 탄저병과 역병은 시설재배보다는 노지재배에서 훨씬 많이 발생하며 그 피해도 대단히 크다. 특히 이 병해들은 강우와 밀접한 관계가 있으며 약제를 살포할 여유도 없이 급진전하므로 잠깐 소홀히 한 사이 포장이 수박전체가 피해를 입는 경우가 허다하다. 여기에서는 앞서 이야기한 4가지 병해를 중심으로 발생생태와 효과적인 방제방법을 알아본다.

As epidemics were spread over the whole Pyeongan province at 1524, Jungjong commanded the government officers like Kim Sunmong to publish Sokbyeokonbang, known as Ganuibyeokonbang, to cope with the epidemics. They regarded the cause of epidemics as abnormal climate, pathogen or grudge, and named the disease on the basis of cause. To prevent epidemics they presented three kinds of method. They used a charm to calm the people, used Sohaphyangwon to keep from getting infected with them and emphasized the importance of individaul sanitation. They proposed compound herb remedies like Sipsintang, Hyangsosan, Seungmagalgeuntang and so forth according to the symptoms. They presented lots of single herbs used for food or easily seeking herbs to lighten the people's expense, in addition.

지금의 교실 수업은 토론학습에 익숙한 학생들로 수업에 흥미를 가지는 수업에 관심을 많이 갖고 있으며 수준별 수업을 통한 심화.보충형과 특별 보충과정으로 학생 지도를 하고 있다. 교실마다 수학 학습을 기피하는 현상이 두드려지고 있으며 개인별 수준 차가 더욱 심한 상태라서 학생들에게 동기를 유발하여 수학에 대한 학습 의욕을 고취하고 교실 밖의 학습자를 교실내로 흡수하기 위한 방법론으로 모둠별 돌림수학, 수준별 모둠 구성을 통해 박수를 치기, 구구단을 이용한 학습과 수학 모둠 노래를 통하여 학습동기를 유발하는 학습 모형을 소개한다. 그리고 수행평가나 포트폴리오, 수학 감상문을 통해 동기 유발이 가능한 실제 학습을 개발하여 공교육의 내실화와 창의력을 유발하는 자아실현의 일환으로 신선한 교실 수업의 보탬이 되었으면 한다.
