The purpose of this study is to determine the optimum slat angle of the venetian blind which was applied at an outer skin of a curtain-wall system. The evaluation of the blind slat angle was performed in terms of the comfortable visual environment and decreased energy consumption. The office building prototype was considered for the analysis and simulation variables include application of blind, blind slat angle and dimming control of lighting. The annual energy consumption and incidence rate of discomfort glare were analyzed using EnergyPlus which is developed by the U. S. Department of Energy for the detailed building energy simulation. As a result, it turns out that when the blind (reflectance: 0.5) was installed, the annual energy consumption was greater than that of the base model. However, when the dimming control was applied, the maximum energy saving of 16.3% could be achieved at a slat angle of $0^{\circ}$. In addition, in case of the base model, the incidence rate of discomfort glare was 84%, while the case of the blind with the slat angle of $0^{\circ}$ showed that the incidence rate of discomfort glare was 42.4%. Consequently, the results showed that the slat angle of $55^{\circ}$ with dimming control was the optimum strategy for the comfortable visual environment and decreased energy consumption.

Background: Bladder calculi greater than 10 mm should be managed via surgical treatment, such as cystolithotomy or percutaneous removal. Because risk evaluation for underlying disease must precede operation, patients are medicated with uroselective alpha blockers or analgesics until the operation occurs. However, disagreement exists about the success of these treatments. Case report: We present a case of a male patient who was hospitalized for sequelae of internal cerebral hemorrhage with complaints of nocturia and perineal discomfort. Abdominal computed tomography showed large bladder calculi. However, because of suspected pheochromocytoma, immediate surgery could not be performed, so we treated him with Korean medicine for 27 days (Daesiho-tang for 27 days and Jakyakgamcho-tang was started at 14th day of treatment, treated till 27th day.) until a cystolithotomy could be performed. Nocturia and perineal discomfort improved after 9 days, and the patient stopped taking acetaminophen. Conclusion: The administration of Daesiho-tang and Jakyakgamcho-tang to a patient with bladder calculi successfully controlled symptoms of nocturia and perineal discomfort until cystolithotomy could be performed.

The purpose of this study was to investigate the quality of life of clients who treated and equipped prosthesis in Eulji University Hospital in Dae-Jun City. The results of this study were as follows. The oral status of Female had more carious tooth than male had. Carious tooth(p<0.05) and losed tooth(p<0.001) was more popular in older female. The frequency of treated tooth was higher under 59 years old female than over 60 years old(p<0.01). In education category, carious tooth(p<0.05) and losed tooth(p<0.000) was more popular in low education than high education In the score of relation of OHIP-14 category and general characteristic, female was significantly higher than male in dysfunction( p<0.05), physical disorder(p<0.001) and activity disorder(p<0.05). The score was significantly higher in older than younger in dysfunction(p<0.05), physical disorder(p<0.001) and activity disorder(p<0.001). The score of education was significantly higher in low education group than high education group in physical pain (p<0.001), mental discomfort (p<0.001). The score of marriage status was significantly higher in marriaged group than other group in dysfunction (p<0.05) and mental discomfort (p<0.05). In the score of relation of OHIP-14 category and oral status, the score of carious tooth group was significantly higher in dysfunction(p<0.05), physical disorder(p<0.05) and activity disorder(p<0.05). The score of losed tooth group was significantly higher in dysfunction(p<0.05), physical pain (p<0.05), mental discomfort(p<0.05), physical disorder(p<0.05) and activity disorder(p<0.01). The score of non treated tooth group was significantly higher in dysfunction(p<0.05), mental discomfort(p<0.05), social disorder(p<0.05) and activity disorder(p<0.05). In the score of relation of OHIP-14 category and the sort of prosthesis, the score of being bridge group was significantly higher than being crown group in activity disorder(p<0.05). The OHIP-14 category and the number of prosthesis was not significant relationship. These results suggest that the information and services of the process of dental prosthesis based on subjective evaluation should be provided to clients rather than based on clinical evaluation. The continued system of oral management should be developed and provided.

Objectives The purpose of this case study was to report improvement of palpitation, epistaxis, nausea, and anorexia after treatment with Dojeokgangki-tang gamibang in a middle-aged woman who has been taking Panax Ginseng continually. Methods Upon beginning her Dojeokgangki-tang gamibang regimen the patient was asked to self-evaluate the degree of discomfort in her symptoms using a using a number scale from 0 (no symptoms) to 10 (most severe). Evaluation of palpitation and chest discomfort was made a high priority. Results The palpitation the patient experienced, and self-evaluated as an "8" on the number scale at the time of her admission to the hospital, had disappeared (become "0") by the fourth day of hospitalization. The numerous symptoms which accompanied her palpitations (chest discomfort, nausea, anorexia, general weakness, weight loss, and depression) also improved accordingly. Conclusions Health functional food can pose serious health risks such as sudden bleeding and palpitations in individuals with pre-existing health problems. One must exercise extreme caution in deciding to take such supplements. As seen in the case of the middle-aged woman, the quality of life of patients who had experienced adverse reactions to such supplements can be treated through the administration of Dojeokgangki-tang gamibang.

Many WMSDs(work-related-musculoskeletal disorders) have been reported in diverse industries and have also attracted much attention in recent years. Neck-related MSD is generally known as one of common WMSDs, especially it happens to workers who are working at the automobile assembly plants and/or shipyards. The awkward posture is considered as a main cause of neck-related MSDs. A neck supporter was developed to prevent neck-related MSDs, and 10 males were recruited to evaluate the newly developed neck supporter by measuring subjective discomfort ratings of whole body, shoulder, neck and neck-muscle activities. Muscle activities from four neck muscle groups(left/right sternocleidomastoid and upper/middle trapezius) were measured while simulating an automobile assembly task. Results showed that the neck supporter help to significantly improve subjective discomfort for whole-body, shoulder as well as neck body parts. The analyses of muscular activities also showed that the activities of left/right sternocleidomastoid muscles were statistically decreased with the neck supporter in this study. The muscle activities of upper/middle trapezius in case of wearing the neck supporter were not significantly different with the muscle activities in case of no-wearing the neck supporter. Overall findings verified that the neck supporter might help to prevent neck-related MSDs based on the current study.

Many workers like welders work in squatting postures with the object on the ground during an entire work shift. It is suspected that such prolonged squatting without any supporting stool would gradually cause musculoskeletal injuries to workers. This study is to examine the physical stress caused by the prolonged squatting and to recommend a safe work/rest schedule for a welding task with squatting posture based on the lab experiments. In this study, 8 healthy student subjects participated in the experiment. They maintained a squatting work posture for 16 minutes with 4 different stool height conditions: no stool; 10cm height; 15cm height; and 20cm height. Every 2 minutes, the discomfort was subjectively assessed with the magnitude estimation method for the whole body, lower back, upper leg and lower leg. Based on discomfort ratings, we found that a 10cm height stool relieved the workload most. Discomfort rating results also indicated that a 20cm height stool showed the highest workload, and the there were no difference in workload between a 15cm height stool and no stool. We recommend to use low height stools and to maintain such working postures no longer than 6 minutes for prolonged squatting tasks.

Purpose: This study was to develop a breastfeeding promotion program and to test effects of the program on levels of breast discomfort, breast size, sodium in breast milk, and type of feeding in mothers with breast engorgement following cesarean birth. Methods: A non-synchronized non-equivalent control group pretest-posttest design was used in this study. The participants were 70 postpartum mothers who were admitted to a postpartum care center and experienced breast engorgement following cesarean birth. The planned nursing intervention was the breastfeeding promotion program consisting of breast massage and 1:1 breastfeeding education, counseling, and support focusing on individualized problem solving provided for 10 days. Fifty-three women completed the program (experimental group 26, control group, 27). Measurements were level of breast discomfort, breast size, sodium in breast milk and type of feeding at pre and posttest. Results: Women who participated in the program experienced lower scores for breast discomfort, greater decrease in breast size, lower levels of sodium in breast milk, and practiced breastfeeding more than those in the control group. Conclusion: Results indicate that this breastfeeding promotion program is effective in reducing breast engorgement and improving breastfeeding practices, and is therefore recommended to enhance breastfeeding promotion practice in postpartum care centers.

Purpose: The EDIN scale (${\acute{E}}chelle$ Douleur Inconfort Nouveau-$N{\acute{e}}$, neonatal pain and discomfort scale) and heart rate variability has been used for the evaluation of prolonged pain. The aim of our study was to assess the value of the newborn infant parasympathetic evaluation (NIPE) index and EDIN scale for the evaluation of prolonged pain in preterm infants with chest tube placement due to pneumothorax. Methods: This prospective observational study assessed prolonged pain in preterm infants with a gestational age between 33 and 35 weeks undergoing installation of chest tubes. Prolonged pain was assessed using the EDIN scale and NIPE index. Results: There was a significant correlation between the EDIN scale and NIPE index (r=-0.590, P=0.003). Prolonged pain is significantly more severe in the first 6 hours following chest tube installation (NIPE index: 60 [50-86] vs. 68 [45-89], P<0.002; EDIN score: 8 [7-11] vs. 6 [4-8], P<0.001). Conclusion: Prolonged pain can be accurately assessed with the EDIN scale and NIPE index. However, evaluation with the EDIN scale is time-consuming. The NIPE index can provide instantaneous assessment of prolonged and continuous pain.

The purpose of this study is to provide useful footwear information for manufacturers and teenagers so that they can produce or purchase proper footwear that would minimize discomfort. For this study, 486 junior high school students were surveyed with a questionnaire. SPSS WIN10 was used to process a statistical analysis such as ferq., factor analysis, t-test, ANOVA(LSD), crosstab, and coefficient correlation. The results are as follows: A significant difference existed between male and female students in purchasing footwear and using evaluation criteria. When they wear shoes for a long time, they usually experience numbness in toes, blisters, heel, bottom on the feet and peeled skin. Female students experienced more foot injuries than males. There were meaningful correlations among purchasing, evaluation criteria, and satisfaction of footwear. Providing proper information is believed very important for teenagers in choosing right footwear. Footwear manufacturers should help them produce suitable shoes, and further help them establish different marketing strategies. To ease the foot discomfort, shoes should be developed with various widths and sizes. Shock absorbing soles and more flexible materials are also necessary.
