In order to evaluate the effect of unilateral tooth clenching, the author observed a feature of producing the symptom complex related to pain and discomfort by the isometric unilateral canine biting under force of 5kg(FS) in Korean 31 adult females within normal masticatory function who were divided into the bilateral, the right and the left group according to their habitual sides of mastication, and analyzed the observed data statistically. The obtained results were as follows: 1. The duration of the isometric unilateral canine biting maintained before the occurrence of symptom complex related to pain and discomfort 66.72 seconds at right side and 39.50 seconds at left side in a group of subjects with bilateral habitual mastication. And the difference of the duration between of unilateral biting side was almost significant (P<0.05). 2. The most frequent region of occurrence of symptom complex related to pain and discomfort by the isometric unilateral canine biting was the contralateral superficial masseter muscle in a group of subjects with bilateral habitual mastication.

Purpose: This study was done to identify menstrual discomfort and dietary habits, and factors related to the menstrual discomforts. Method: Participants were 320 female middle school students in G city. The Menstrual Discomfort Questionaire(MDQ) and dietary habit lists were used as tools. Results: Factors related to MDQ were found to be the VAS scores (r=.361, p=.002), a mount of menstrual bleeding (r=.131, p=.019), height (r=.134, p=.016), adequacy of meal time (t=7.19, p=.008), consumption of milk & milk products (F=3.20, p=.042) and, hot, salty & irritant foods (f=8.01, p=.000), eating more than 3 kinds of side-dishes with each meal (F=8.32, p=.000), and various protein foods (F=5.15, p=.006). In stepwise regression, 4 variables (VAS scores, height, hot, salty & irritant foods, more than 3 kinds of side-dishes with each meal) explained $20.3\%$ of the variance in the total MDQ scores. Conclusion: Reduction of hot, salty & irritant foods and having more than 3 side-dishes with each meal would be effective in menstrual discomfort management. As well, good and, balanced dietary habits should be encouraged for early adolescent girls. To keep up with the ideal dietary habits, nutritional education & counseling should be continued. In a further study, a replication study with larger samples and more specified nutritional assessment are recommended.

Purpose: This study was conducted to identify the effects of video-audio information provision on physical discomfort, anxiety and nursing satisfaction of the clients for gastroscopy. Methods: The study design was nonequivalent control group pre-post test design. The subjects were 50 patients who visited H hospital health examination center for gastroscopy. Video-audio information developed by the authors was used as educational material for the treatment group. The data were collected between September 15 and November 15, 2010. The study instruments were the State-Trait Anxiety Inventory, the Physical Discomfort Scale, and the Nursing Satisfaction Scale. Results: The level of anxiety and physical discomfort in the treatment group were not significantly different from that in the comparison group (t=-0.28, p=.781; t=-0.34, p=.741). The level of clients' satisfaction with nursing care in the treatment group was significantly higher than in the comparison group (t=-4.12, p<.001). Conclusion: Use of video-audio information was effective in the increase in satisfaction with care. Therefore, it could be useful in the nursing practice, and be utilized as a way of nursing intervention to improve nursing satisfaction.

Thirteen taxi drivers as the subject in the experiment were exposed to vertical vibration which is controlled on a rigid seat reflecting vibration on passenger vehicle. They were employed not only to get human response of objective measurement but also to make subjective evaluation of the vibration. The subjective evaluation was estimated using the absolute discomfort threshold of the controlled vibration, which was achieved with the three-down one-up method that is widely used in the field of psychophysics. As the result, apparent mass and apparent eccentric mass as objective human response tend to gradually decrease when frequency of the vibration increases. The absolute discomfort threshold was increased in case of increasing the frequency. Concludingly, the subjective discomfort evaluation is highly correlated with the objective human responses at the range of idle vibration on passenger vehicle.

Purpose: This study was conducted to develop a postpartum care program and to evaluate the effects of the program on postpartum activity and postpartum discomfort in primiparous women. Methods: For this control group quasi-experimental study, primiparous women who had a normal delivery at OBGYN clinics in G-city and then went home with assistance from their mothers participated from April 10 to August 2, 2006. The participants were assigned to an intervention group of 25 mothers or a control group of 23 mothers. Data analysis was performed by using SPSS/win10.0 PC+. $X^2$-test and t-test, and repeated measure ANOVA. Results: The results showed that the degree of postpartum activity(F=4.66, p=.036) and the degree of postpartum discomfort(F=7.98, p=.007) were supported statistically with significant differences between the two groups. Conclusions: Therefore, this program needs to be applied as a new nursing intervention because this postpartum care program was proven useful as effective postpartum care.

Purpose: This study was to compare the effects of early ambulation to usual care of late ambulation in patients with transarterial chemoembolization on back pain, discomfort, and puncture site complications. Methods: A nonequivalent control pretest-posttest design was used. Total 40 patients were recruited from a gastrointestinal unit of an urban general hospital in Seoul, South Korea. The experimental group began to ambulate after 4 hours of bed rest with a compression bandage after receiving transarterial chemoembolization. The control group stayed in bed with a compression bandage overnight. Results: Back pain was not significantly different between the two group. The experimental group reported significantly lower discomfort than the control group. There was no incidence of bleeding complications on puncture site between two groups. Conclusion: The results of this study showed that early ambulation with four hours of bed rest after femoral sheet removal did not cause bleeding complications compared to the usual care and even decreased patients' level of discomfort due to bed rest. Repetitive research on the effect of short bed rest is warranted for its clinical utilization.

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.

Purpose: The purpose of this study was to examine the effects of cold oral gargling on oral discomfort among Non-Hodgkin's lymphoma patient undergoing chemotherapy. Method: An quasi-experimental, nonequivalent control group design was used. Thirty two patients receiving chemotherapy at G hospital in P city were recruited from August 1, 2002 to October 20, 2002. Sixteen were conveniently allocated into the experimental group and 16 into the control group. Participants in the experimental group used cold oral gargling while their counterparts used room temperature oral gargling. Subjective and objective oral discomforts were measured by the instruments developed by Beck. The SPSS WIN 10.0 program was used to analyze the data with t-test, ${\chi}^2$ -test, and repeated measures ANOVA. Findings: The participants in the experimental group reported less oral discomfort and showed better oral conditions than those in the control group at the post 7th, 14th, and 21st days. Participants in the experimental group reported better oral conditions in taste, tongue, eating, and saliva than those in the control group. Conclusion: The cold oral gargling seemed to be more beneficial than room-temperature oral gargling in reducing oral discomfort for the Non-Hodgkin's lymphoma patients undergoing chemotherapy.

This study was focused on how the various materials of footwear affect the preferences of functionality and the level of discomfort when wearing. Datas were collected using questionnaire, age of 20's to 50's of female and male. Results were analysed using SPSS WIN 2.0 through t-test and ANOVA test. Results are as follows: In the preferences of materials of footwear, datas showed the shoes are of genuine leather, the sneakers are of textiles, the sandals are of man-made leather and the boots are of genuine leather. The important factor to the preferences of the materials were the leathers in the durability, the man-made leathers in easy-care and maintenance, the rubber and the complex materials in comforts. The level of the discomforts of the footwear were highly ranked in genuine leather, the man-made leather and the complex material with man-made leather and textiles followed. Man-made leather and the textiles represented the discomfort in the ankle. Mostly discomforts of the footwear showed in the sole and the top side of the foot in all kinds of footwear. The preferences in functionality were collected by the female, also female preferred the comfort the first, male preferred the durability. And the texture and the durability were highly preferred in aged female and male.
