The upper-body characteristics of the right-handed and the left-handed are examined and compared through 1-dimensional measurement and 2-dimensional measurement. The results were as follows: 1. According to 1-dimensional measurement results, the clearest differences were seen in girth items rather than height or length items. In particular, hand girth, lower arm girth, and upper arm girth were bigger on the left side in the left-handed group and the right side in the right-handed group. This is thought to be relevant to the arm muscles frequently used. 2. According to 2-dimensional measurement results, significant differences appeared in the females of the left-handed group: shoulder point among width items. In the right-handed group, some differences of significance were shown in females (shoulder point, rear armpit point, and B.P. point among width items) and males (front neck point among extreme vertical distance items). In summary, the body type characteristics of the left-handed and the right-handed reveal great differences in the items related to arm length and arm girth. In other words, the sleeve and shoulder patterns production based on the right-handed don't rightly reflect the somatotype characteristics of the left-handed. In addition, in the cases of athletes, laborers, and the disabled who frequently use particular muscles or parts of the body, this sort of research in the patterns is consistently needed in order to reflect the size differences in girth items in upper body.

본 논문에서는 composite right/left-handed 전송 선로를 이용한 주파수 체배기를 제안하였다. 제안된 주파수 체배기의 left-handed 전송 선로는 기본 주파수($f_0$) 성분을 억압하였고, composite right/left-handed ${\lambda}/4$ 개방 스터브는 원하지 않는 고조파 신호 성분들을 제거하였다. Left-handed 전송 선로와 composite right/left-handed ${\lambda}/4$ 개방 스터브를 조합하여 사용함으로, 오직 3차 및 4차 고조파와 같은 원하는 고조파 신호들만을 효과적으로 얻을 수 있었다. 본 논문의 타당성을 보이기 위해 기본 주파수를 1 GHz로 하는 주파수 체배기를 설계하고, 측정하였다. 설계된 주파수 체배기의 입력 전력을 0 dBm으로 하였을 때, 측정된 3차 체배기와 4차 체배기의 출력 전력은 각각 -5.67 dBm과 -6.43 dBm이다.

본 연구에서는 Right-handed 전송 선로(RHTL)의 저역 통과 특성과 Left-handed 전송 선로(LHTL)의 고역 통과 특성을 결합한 구조의 가변 대역 저지 필터를 제안하였다. RHTL, LHTL의 분산 특성을 ABCD 행렬을 통해 구하고 차단 주파수를 계산하였다. 바렉터 다이오드와 칩 인덕터를 이용하여 RHTL,LHTL 단위 셀을 구성하고 각각 4개의 단위 셀이 연결된 RHTL, LHTL을 병렬로 연결하여 가변 대역 저지 특성을 구현하였다 제작된 가변 대역 저지 필터는 저역 차단 주파수 $280{\sim}395$ MHz, 고역 차단 주파수 $770{\sim}940$ MHz의 가변 특성을 갖는다.

본 논문에서는 CRLH(Composite Righ/Left Handed) 전송선과 PIN 다이오드를 이용한 이중대역 RF 스위치를 제안하였다. 일반적인 RF 스위치가 RH(Right Handed) 전송선 및 PIN 다이오드로 구성되는 것과는 달리, 제안된 RF 스위치는 CRLH 전송선을 이용함으로써 이중대역 특성을 만족하였다. 설계된 CRLH전송선은 Open-Stub를 이용하여 PIN 다이오드 패키지 인덕턴스로 인한 격리도 감소를 해결하였다. RF 스위치는 GSM 주파수 대역인 900MHz와 DCS 주파수 대역인 1.8GHz의 이중 대역에서 설계 및 제작하였다.

It is known that one out of every ten people walking down the street is left-handed. In daily living, left-handed people come across hardwares and facilities that were designed for right-handed people. Most tools, utensils, office equipment, home appliances, clothes, medical instruments, sporting goods, weapons, and public facilities are made for the right-handed person. Many left-handed people thus have trouble with living in our environments. In this study, 1,933 Korean male and female subjects aging from 10 to 82 were selected to investigate the various statistics about hand dominance and their employment characteristics of preferred hand in handling diverse products and facilities. The statistics showed that 5.6% were left-handed and 7.6% were ambidexter. There were strong tendency that left-handed people use more left hand when take action that force is required than when take exquisite action. Ambidexter and right-handed people use more right hand when they take exquisite action is required than when take action that force is required. It was found from these results that people use their hands differently depending on the hand dominance when they handle things, hence this should be considered in designing hand control devices.

본 논문에서는 right/left-handed특성을 이용한 8 포트 동위상 전력분배기를 제안한다. 이 전력분배기는 사용되는 전송선의 전기적 길이에 상관없이 동위상 분배가 가능하기 때문에 전력 분배기의 크기를 크게 줄일 수 있다. 전력분배기에 사용되는 전송선의 길이가 짧을수록 광대역 특성을 보이며 분배기의 크기는 줄어든다.

It is widely known that language functions in our brains are lateralized to the left hemisphere and spatial recognition functions are lateralized to the right hemisphere. It is also known that handedness is closely related to the lateralization of brain functions. However, at what point in the brain‘s development the lateralization of brain functions takesplace is still disputed. This study sought to find differences in linguistic and spatial abilities between left-handed and right-handed children, and provide objective data on the relationship between the handedness and the brain lateralization. 19 left-handed children and 20 right-handed children aged 5 were chosen through questionnaire for this study and the K-WPPSI simple intelligence test was used to check the homogeneity of two groups. The results showed that the differences inlinguistic and spatial ability between left and right-handed children were not statistically significant.

In this paper, a homogeneous dual composite right/left-handed (D-CRLH) transmission line (TL) is proposed by using a defected ground structure (DGS) on the ground plane. In order to satisfy a homogeneity condition of metamaterial, a subwavelength unit cell is designed by way of a spiral DGS and a meander stub. From a dispersion diagram, it is expected that the frequency bands for the left-handed (LH) property is 3.5 - 4.4 GHz. At 3.8 GHz in the LH band, backward propagating phenomenon is observed from full-wave analysis. The experimental results show that the proposed TL has a stop-band in 1.75 - 3.6 GHz.

This study was conducted to find out effect of dynamic balance performance in normal adult when obscuring vision in half of the both eye and to prepare the basic data treatment of brain damage patient with visual field deficit. The subject for this study included 40 healthy right-handed and 20 left-handed were dynamic balance performance when obscuring vision in half of the both eye. who age from 20 to 30 years in normal adult without neurosurgical orthopedic, performance balance disability or other medical disorders. Of these individuals 20 right-handed and 20 left-handed were executed dynamic balance performance when obscuring vision in half of the both eye. individuals of right, left-handed were executed dynamic performance when obscuring vision in half of the both eye measure with a Balance Performance Monitor (BPM) Data print Software Version 5.3. In other to determine the statitsical significance of the result, instrumentation was used to t-test, chisquare of the SAS(Strategic Application Software) The result of the study were that: 1) Significant differences in LOS were found right-handed and left-handed subject when dynamic performance without obscuring vision and obscuring vision(p<0.05). 2) Significant differences in LOS were founded left-handed when dynamic performance were executed obscuring vision and without obscuring vision(p<0.05). 3) Significant differences in LOS were founded right-handed when dynamic performance were executed obscuring vision and without obscuring vision(p<0.05).

Objectives: The pulse diagnosis to identify the symptoms has been considered important in Korean medicine. The position and character of disease would be confirmed by pulse diagnosis of left and right radial artery. This paper is to analyze the characteristics and differences of left and right blood vessels. Methods: In this study, left and right radial artery and dorsalis pedis artery was measured and analyzed by using condenser typed pulse analyzer. Commercially available pulse analyzer was used to measure the radial artery. The pulse wave was measured in 20 laboratory healthy men and women. The blood vessel aging degree and index of augmentation of blood vessel was obtained from the measured pulse wave graph and the characteristics and differences of the left and right blood vessel was analyzed. Results: The significant difference of pulse transit time between the right handed and non-right handed was not found. The correlation of radial artery and dorsalis pedis artery had no significant difference. By obtaining the blood vessel aging index (AGI) and augmentation index (AI) of blood vessel at the left and right radial artery, the significant difference between right handed and non-right handed was not found. Conclusions: The result of this study would help to explain the characteristic of blood vessel with respect to the left and right handed. We suggest that research of pulse wave of the left and right blood vessel using pulse analyzer should be needed in further study.
