In this experiment, we proposed and implemented a disease forecasting system using a received signal strength indication ZigBee-based wireless network with a 3-axis acceleration sensor to detect illness at an early stage by monitoring movement of experimentally infected weaned piglets. Twenty seven piglets were divided into control, Salmonella enteritidis (SE) infection, and Escherichia coli (EC) infection group, and their movements were monitored for five days using wireless sensor nodes on their backs. Data generated showed the 3-axis movement of piglets (X-axis: left and right direction, Y-axis: anteroposterior direction, and Z-axis: up and down direction) at five different time periods. Piglets in both infected groups had lower weight gain and feed intake, as well as higher feed conversion ratios than the control group (p<0.05). Infection with SE and EC resulted in reduced body temperature of the piglets at day 2, 4, and 5 (p<0.05). The early morning X-axis movement did not differ between groups; however, the Y-axis movement was higher in the EC group (day 1 and 2), and the Z-axis movement was higher in the EC (day 1) and SE group (day 4) during different experimental periods (p<0.05). The morning X and Y-axis movement did not differ between treatment groups. However, the Z-axis movement was higher in both infected groups at day 1 and lower at day 4 compared to the control (p<0.05). The midday X-axis movement was significantly lower in both infected groups (day 4 and 5) compared to the control (p<0.05), whereas the Y-axis movement did not differ. The Z-axis movement was highest in the SE group at day 1 and 2 and lower at day 4 and 5 (p<0.05). Evening X-axis movement was highest in the control group throughout the experimental period. During day 1 and 2, the Z-axis movement was higher in both of the infected groups; whereas it was lower in the SE group during day 3 and 4 (p<0.05). During day 1 and 2, the night X-axis movement was lower and the Z-axis movement was higher in the infected piglets (p<0.05). Overall, the movement of infected piglets was altered, and the acceleration sensor could be successfully employed for monitoring pig activity.

In this paper, the geometry between horizontal and vertical movement of lens is studied for automatic vergence control of horizontal moving axis stereo camera. When the disparity of stereo remains contant, the horizontal movement of camera lens for image disparity and the vertical movement for image focus have linear geometry. Using this linearity, we can control the vergence of stereo camera only by focusing of stereo camera lens.

Psychological wellbeing, Middle aged women, Wellbeing with depression tendency, 율동적 동작 프로그램, 우울성향 중년여성 %600an This study was designed to confirm the effects of the Dance Movement Program on psychological health in middle-age women with depression tendency. 67 women with mile to moderate depression scoring between 16-25 were selected among 235 responded to CES-D (Radloff, 1977, Cho and Kim, 1993). The 46 volunteered to participate in the study were assigned the control. 7 attritions occurred during the course of the experiment leaving thirty-nine subject : nineteen experimental and twenty control, for the final analysis. Research subjects revealed to be homogenous demographically and by health-related variables. The 50-minute Dance Movement Program was performed by the experimental group 3 times a week for eight weeks, from October 6 to November 29, 1997. Depression, life satisfaction, self efficacy were measured before and after the course of Dance Movement Program. Plasma serotonin was measured to identify its relationship with depression, Homogeneity tests revealed satisfactory level on relevant research variables. Data were analyzed by $x^2$-test, paired and unpaired t-tests. The results are as follows : 1) The hypothesis that depresson score of experimental group will decreased than control group was supported by t-test(t=2.20, P=.0021) 2) The hypothesis that life satisfaction score of experimental group will increased than control group was supported by t-test(t=1.42, P=.0049). 3) The hypothesis that self-efficacy score of experimental group will increased than control group was not supported by t-test(t=6.20, P=.0616). 4) The hypothesis that level of plasma serotonin will increased than control group was not supported by t-test(t=1.88, P=.0524) Thus, the effects of the Dance Movement Program for the improvement of psychological health gram for the improvement of psychological health for the middle-aged women with depression tendency are scientifically confirmed by this study.

High-rise buildings are widely being constructed in the Middle-East, South-East, and East Asia. These buildings are usually willing to stand for the landmark of the region and, therefore, exhibit some extraordinary features such as super-tall height, elevation set-backs, overhangs, or free-form exterior surface, all of which makes the construction difficult, complex, and even unsafe at some construction stages. In addition to the elaborately planned construction sequence, prediction and monitoring of building's movement during construction and after completion are required for precise and safe construction. This is often called the Building Movement Control during construction. This study describes Building Movement Control of the KLCC Tower, a 58-story office building currently being built right next to the famous PETRONAS Twin Towers. The main items of the Building Movement Control for the KLCC Tower are axial shortening and verticality. Preliminary prediction of these items are already carried out by the structural design team but more accurate prediction based on construction stage analysis and combined with time-dependent material testing, field monitoring, and site survey is done by the main contractor. As of September 2010, the Tower is under construction at level 30, where the plan abruptly changes from rectangle to triangle. Findings and troubleshooting until the current construction stage are explained in detail and implementations are suggested for future applications.

An observation and evaluation of the reproducibility of the mandibular movements has been a integral part of a test for mandibular function and dysfunction. After Pantographic Reproducibility Index(PRI) was introduced in dentistry, many authors have used the index for investigation of mandibular movement function, especially in condylar compartment. Howerer, the difficult and time-consuming work of instrumentation for getting the PRI has been a major obstacle in using pantograph. This study was performed to try a new mandibular reproducibility index, so-called BioEGN reproducibility index(BERI), calculated from mandibular trajectory recorded with BioEGN. 26 dental students without any signs and symptoms of temporomandibular disorders and 22 patients with temporomandibular disorders took part in this study and classed to control group and patients group, respectively. Pantronic and BioEGN were used to record and calculate the indices, PRI and BERI. PRI had only one value, but BERI had two values of outgoing and incoming movement in each scale. With two scales of small and large, as a result, BERI had four values in this study. PRI corresponded to BERI in small scale on outgoing total movements. The data were calculated and analyzed with SAS/stat program and the conclusion of this study were as follows : 1. In every scales, in each movement, BERI on outgoing movement in control group was lower than that in patients group, respectively, but BERI on incoming movement was only different in one side movement, that was, left excursion. 2. The difference between BERI on outgoing movement and BERI on incoming movement was only shown in small scale on total movements, not in each movement, in control group. However, there was generally a positive correlationship between BERI on outgoing movement and BERI on incoming movement in each movement in both groups. 3. Simple statistics of PRI was similar to that of BERI on total movements in small scale, but there was a negative correlation between PRI and BERI on total movements in large sclae only in patients group.

EEG(Electroencephalogram) provides a possibility of communicating between a human and a computer, called BCI(brain computer interface). EEG evoked by a movement has been often used as a control command of a computer. This study is to predict human movements by EEG parameters showed significant consistency. Three undergraduate students were asked to move both hands and foots thirty times respectively. Each movement consisted of single and three consecutive movements. Their EEG signals were analyzed to obtained ERD(Event Related Desynchronization) and ERS(Event Related Synchronization). The results showed that ERD and ERS could be used as a significant classifier identifying either single movement or repetitive movement of human limbs. The number of repetition of movement could be used to various control commands of a computer.

To study the characteristic of the weight center control of humans, the tracking control capability of circular and wave motion by weight center movement was conducted by using the force platform. The control performance(the integrated value of the $|Object\;value(X)-Control\;Value(Y)|^{2}$) and control trace record was used to evaluate the individual performance characteristics. The size of the population for this study was 73, which consisted of engineering students, students majoring in taekwondo, students majoring in dance, all of which were in their twenties, and also people in their sixties. The results of this study indicate that the weight center control characteristics of humans can be represented by the evaluation method and values. People who were capable of tracking the object did not stop nor overshot the objective. In addition, habits or training characteristics and aging seemed to influence the performance of the subjects. In the future, development of different objectives for weight center control could be used to determine the severity of the disease of the subject and the effects of the treatment.

In this study, we developed a new human arm movement detection system using electrical bio-impedance method with several skin-electrodes. The correlation coefficients of the joint angle and the impedance change from human arm movement was obtained using a goniometer and impedance measurement system developed in this study. The correlation coefficients of the wrist and the elbow movements were 0.94 and -0.99, respectively. This system was applied to control a robotic arm by converting the measured impedance to joint angle to confirm the validity of the proposed system. In conclusion, we confirmed that this system can control the robotic arm according to arm movement without any limitation of movement. This system showed possibility that upper arm movement could be easily measured by impedance measurement system with a few skin-electrodes.
