Visual images are very close to our living and we make decisions and choose behavioral options with the visual images on mass media. In current-affair documentary programs, interviews have potential effects that can change public opinions on important issues. Therefore, it's a consequence that the study examined how different expressions of visual images in documentary. Using preceding research methods, this study focus on form, color, movement and depth of visual images. This study analyzed quantitatively all interview shots with 15 current-affair documentary programs from major TV stations such as KBS, MBC and SBS. The findings of the study are 1) half of interview shots used the visual image expressions to hide interviewees' face according to the shield law, 2) choosing close-up shots in company with bust shots, 3) using natural lights and hand-held camera techniques for interviews, and 4) showing wide angles without depths of visual image.

Emotional interaction in virtual reality is necessary of social communication. However, social emotion has been tried to be less recognized quantitatively. This study was to determined social gaze of emotion in business domain. 417 emotion words were collected and 16 emotion words were selected to Goodness of Fit. Emotion word were mapped into 2 dimensional space through multidimensional scaling analysis. Then, X axis defined dimensions of cooperation, competition, and Y axis of low focus and high focus through the FGD. 52 subjects were presented to stimuli for emotion and gaze movement data were collected. Independent t-test results showed that the gaze factor increased in the face, eye, and nose areas at cooperation, and the gaze factor increased in the right face and nose areas at the low focus. It is expected that this will be used as a basic research to evaluate emotions needed in business environment in virtual space.

The dose distributions within the real volumes of tumor targets and critical organs during internal target volume-based intensity-modulated radiation therapy (ITV-IMRT) for liver cancer were recalculated by applying the effects of actual respiratory organ motion, and the dosimetric features were analyzed through comparison with gating IMRT (Gate-IMRT) plan results. The ITV was created using MIM software, and a moving phantom was used to simulate respiratory motion. The doses were recalculated with a 3 dose-volume histogram (3DVH) program based on the per-field data measured with a MapCHECK2 2-dimensional diode detector array. Although a sufficient prescription dose covered the PTV during ITV-IMRT delivery, the dose homogeneity in the PTV was inferior to that with the Gate-IMRT plan. We confirmed that there were higher doses to the organs-at-risk (OARs) with ITV-IMRT, as expected when using an enlarged field, but the increased dose to the spinal cord was not significant and the increased doses to the liver and kidney could be considered as minor when the reinforced constraints were applied during IMRT plan optimization. Because the Gate-IMRT method also has disadvantages such as unsuspected dosimetric variations when applying the gating system and an increased treatment time, it is better to perform a prior analysis of the patient's respiratory condition and the importance and fulfillment of the IMRT plan dose constraints in order to select an optimal IMRT method with which to correct the respiratory organ motional effect.

The purpose of this study was to investigate the effect of sensory-motor centered group occupational therapy program on self-regulation and executive function in first grade elementary school maladjusted children. It is a case study through pre-post design with a total of 3 subjects. A pre-and post-test was conducted to determine the change in Self-Control Rating Scale and to find out the execution function by Bruininks-Oseretasky Test of Motor Proficiency. The sensory-motor centered group occupational therapy program performed movement activities based on vestibular sensation, proprioception, and tactile sensation, and the task was selected by investigating the child's preference for activity. As a result, subjects 1 and 2 children showed improved self-regulation and executive function. Based on the results of this study, it is considered that the group-centered sensory-motor program can be provided to children who show maladjustment in school by linking the educational field and clinical practice.

The purpose of this study was to demonstrate exploring the field application of combined cognitive-motor learning program based on proprioceptive neuromuscular facilitation and Bartenieff Fundamental program. The combined cognitive-motor learning program(CC) was applied to the 10 MCI elder while 10 elder in occupational therapy(OT) took cognitive learning class. MMSE-K, Time up & go test(TUG), Tandem gait test(TA), GQOL-D were measured and analyzed. The collected data were analyzed by Independent & Paired T-test. The results were as follows: Both groups showed similar learning effect in MMSE-K test. However, in TA & GQOL-D test, CC group showed significant learning effect than OT group. From these result, we conclude that combined cognitive-motor learning program is valuable as alternative program for cognitive development and social development as well as physical development of MCI elder.

The purpose of this study is to develop a program that computes the position of the instantaneous center of rotation while an object moves in a circular motion. For this study, a mathematical algorithm was developed and implemented on the experimental data. Data for pitching (40m carry) and putting (4m) strokes were obtained from a skilled female golfer. A computer program (Centering 1.0) calculated the experimental data and found the radius of the instantaneous center of rotation. When the data were taken broadly, the program produced an error distance of radius. When the data were divided gradually, the program produced a very close instantaneous center of rotation. On comparing pitching and putting strokes, putting was found to have a greater radius than pitching. The instantaneous centers of rotation of putting were not in the golfer's body rather, they were 3m away from the club head. The Centering 1.0 program can calculate the instantaneous center of rotation with at least three sets of experimental data.

The purpose of this research was to investigate the effects of respiratory rehabilitation using a wind instrument for patients suffering from spinal cord injuries. From January 15, 2018 to April 15, 2018, we conducted ten 1-hour sessions of a harmonica program with eight patients with spinal cord injuries with average age of 37 years who could not perform abdominal breathing by themselves. We measured and compared patients' breathing capacity before and after the 10 sessions. Designed particularly for patients with spinal cord injuries resulting in a limited range of neck movement, the study used a 10-hole diatonic harmonica whose length was relatively short. For those patients who had difficulty using their hands, a harmonica holder was provided. Participants were trained to play simple tunes. They were guided to use abdominal breathing to make sounds, with emphasis on those parts requiring long and strong breathing. The results showed that for all eight patients both their breathing volume and their inspiratory volume increased following participation in the harmonica program. Also, the program had psychological benefits (e.g., more life satisfaction and less sadness) and additional physical benefits (e.g., less dizziness due to low blood pressure and better phlegm spitting). This study offers a unique way to help patients with spinal cord injuries to improve their breathing capacity, which may also be associated with a greater quality of life.

The purpose of this study was to demonstrate the effects of 8weeks Kettlebell training on the FMS and Balance in Middle school baseball player. Fourteen middle school baseball players were randomly assigned to a kettlebell group (n=8) and a control group (n=6), and kettlebell training was applied twice a week for 60 minutes. And the FMS, Y-balance test and static and dynamic balance test using smart shoes were tested before and after kettlebell training. Repeated two-way ANOVA measures was performed both before and after the exercise to verify the effect of kettlebell training. Also, if there was an interaction between time and group, a paired sample t-test was performed for each group. As a results of the study, FMS score showed a significant difference in IL (Inline Lunge) and TS(Total Score), and there was no significant difference in other variables of FMS. The YBT score showed a significant difference in all YBT variables except for the left AT. And the balance test using smart shoes, there was no significant interaction effect between group and period in all variables. In conclusion, it was found that the application of kettlebell training in middle school baseball players had an effects on the FMS and YBT scores related to functional movement and functional balance, but it did not affect the static/dynamic balance test using smart shoes evaluated by the foot pressure method. It seems that the results of this study can be provided as basic data necessary for planning a training program for middle school baseball players.
