Purpose: This study aim to determine the effect of chewing gum on the reduction of postoperative ileus and recovery after surgery. Methods: The study was conducted as a randomized controlled trial among 82 patients who underwent spine surgery between May 2015 and October 2015. Patients in experimental group chewed sugarless gum 3 times daily for 30 minutes each time until POD 5. Abdominal discomfort, the first defecation, and CAS score (Constipation Assessment Scale) were monitored. Results: After the experiment, abdominal discomfort was significantly decreased in the experimental group compared to that of the control group (F=2.46, p=.044). However, the first defecation occurred on postoperative hour 69.6 in the chewing gum group and on hour 60.2 in the control group (t=-1.63, p=.107). CAS was significantly decreased in the experimental group compared to that of the control group (F=3.51, p=.012). Conclusion: Chewing gum is expected to help patient recover after surgery as safe nurse intervention which can reduce abdominal discomfort and constipation during early postoperative days after spine surgery.

Purpose: This study aimed to determine the effect of hand massage in patients who underwent transradial percutaneous coronary intervention. Methods: This was a quasi-experimental study with a nonequivalent control group and non-synchronized design. The study included 30 patients in the experimental group and 30 in the control group. Hand massage was performed 2 times for 5 minutes each in the experimental group and the control group only received usual nursing interventions. Pain, level of discomfort, and vital signs were defined as key outcome measures, and the data were analyzed using the chi-square test, an independent t-test, Mann-Whitney U test, repeated-measures analysis of variance, and Friedman test. Results: Significant differences were observed between the 2 groups in the pain score (F=7.91, p=.003), discomfort score (F=18.15, p<.001), pulse (F=12.92, p<.001), and respiration rate (${\times}^2=19.35$, p<.001). Conclusion: Hand massage can be a helpful nursing intervention for transradial percutaneous coronary intervention by reducing pain and discomfort to a considerable degree.

The recent rise of the three-dimensional television (3DTV) industry has led to a wide exploitation of the dual-lens stereoscopic camera. However, when the zoom-in function is used, it is possible that a camera object is magnified only with a fixed convergence point, thereby leading to visual discomfort. In this paper, we propose several methods based on which a convergence point can be adjusted to prevent visual discomfort during zoom-in for a dual-lens stereoscopic camera. Further, we produce 3D contents by applying the proposed methods to certain cases and at certain distances and conduct a subjective evaluation. On the subjective evaluation, 48 subjects watch the 3D contents created by the proposed methods and score the stages of the visual comfort. The result of the subjective evaluation shows that some of the proposed methods are more efficient than the others. We hope that these proposed high-efficiency methods can be applied to produce a dual-lens stereoscopic camera that allows convenient stereoscopic photography.

Purpose: The purpose of this study was to compare effects of intravenous fluid warming and forced-air warming on perioperative body temperature, Blood Pressure, Pulse and thermal discomfort after gastrectomy under general anesthesia. Methods: Data collection was performed from October, 2009 to February, 2010. The intravenous fluid warming group (27) was warmed through an IV line by an Animec set to $37^{\circ}C$. The forced-air warming group (27) was warmed by Bair Hugger System. The warming continued from induction of general anesthesia to two hours after completion of surgery. The data was analyzed by t-test, $X^2$, repeated measures ANOVA using SPSS/WIN 17.0. Results: There was a significant difference of body temperature and thermal discomfort between the intravenous fluid warming group and the forced-air warming group. Conclusion: We need to explore the effects combination of the intravenous fluid warming and the forced-air warming, and other warming therapy and the efficiency of modalities with regards to cost benefit is also needed.

Objectives : The objective of this study was to investigate the relationship between the status and necessity of dental prosthesis and mastication function in the Korean elderly. Methods : This study investigated 4,557 elderly people aged over 65 in the 5th Korea National Health and Nutrition Examination Survey(2010-2012). Frequency analysis, ${\chi}^2$ test, and logistic regression analysis were used. Results : Those aged over 75 complained of greater discomfort in mastication function than those from 65 to 74, and it was statistically significant(p<0.001). Mastication discomfort was not so significant in those with higher education and higher income(p<0.001). Those who did not use prosthesis tended to have better mastication function(p<0.001). Denture users complained of mastication discomfort when they used it(p<0.001). Conclusions : This study verified the relationship between the discomfort in mastication and related factors, and will provide the basic data for the access to dental clinic services.

The purpose of this study was to test whether adhesive taping therapy, one of rehabilitation, helps to relieve chronic low back pain. Sample were selected from 35 outpatients at oriental medicine hospital in the period from April 20 to June 20, 1998. The research design was one-group pretest - posttest design. The pretest included measuring discomfort depending on the scope and types of a range of motion, and their pain by their activity of daily living(ADL). In this research design, a treatment was to expose adhesive taping therapy to samples. The posttest included remeasuring of their discomfort and pain by ADL. The results of this study was as follows: Hypothesis I was that the discomfort score of the post-treatment group had lower than does that of the pre-treatment group. This study accepted the hypothesis (t=2.70, p=.015). Hypothesis II was that the post-treatment group had the pain score by ADL lower than does the pre-treatment group. Empirical results showed statistical significance(t=4.53, p=.000). In summary, the effect measured by the discomfort with a visual analog scale was statistically significant. The degree of pain according to postures in ADL also showed statistical significance. Consequently, these findings showed that the adhesive taping therapy was effective to alleviation of chronic low back pain.

This paper suggests the best work conditions, including short break time and number of mouse clicks on a computer, to prevent MSDs(Musculoskeletal Disorders) on VDT(Visual Display Terminal) work. Discomfort measures are calculated according to the Borg's CR-10 Scale. The short break time conditions are grouped into 7, 15, and 30 seconds after every 10-minute work period and the number of mouse clicks are divided into 10 clicks/min, 20clicks/min, and 30clicks/min. The result of the ANOVA on the shift value of subjective discomfort shows the following: 1) Regarding the break time and the number of mouse clicks, there are statistical differences between the measured values for the neck and the wrist(p<0.05). 2) Regarding the number of mouse clicks, there are statistical differences between the measured values for the shoulder and the forearm(p<0.1). 3) Regarding the break time and the number of mouse clicks, there are no statistical differences between the measures values for the eyes, upper arms and back(p<0.1).

Even though a dual lens stereoscopic camera allows for convenient stereoscopic photography, the necessity for the research comes up, since the dual lens stereoscopic camera can cause visual discomfort during zoom-in due to the fixed convergence point. We propose a method based on which a convergence point can be adjusted to prevent visual discomfort during zoom-in for a dual lens stereoscopic camera. First, the relational model is classified into nine kinds and defined, depending on locations of focus, object, and convergence point. And then, the method to minimize visual discomfort is suggested by adjusting convergence point on the given model. We also implement the suggested methods with anaglyph computer graphic and demonstrate the superiority of them.

Use of a glove made of materials with a low elasticity decreases the performance of the hand such as agility, dexterity, range of motion, and grip strength. The present study examined if the adverse effects of a low-elastic glove can be reduced by a design which accommodates the changes of hand surface lengths by hand motion. Two glove designs which provide patches of elastic cloth and pleats at the finger joints and knuckle were developed by considering the hand surface length changes, and then compared with two conditions(bare hand and conventional glove design that does not consider the dynamic characteristics of the hand dimensions) in terms of completion time in peg board insertion task, maximum grip strength, discomfort in hand motion, discomfort in force exertion, and overall discomfort by 24 right-handed participants. The test results confirmed that wearing of a glove significantly reduced the agility and grip strength capability of the hand and indicated that the novel designs were effective to lessen the performance decreases compared to the conventional design. Also, of the glove designs, the pleat glove design was found most preferred for both better hand performance and less subjective discomfort.
