Purpose: This study aimed to compare the effects of the Difflam spray 0.3% with the sodium bicarbonate-normal saline spray on oral care for postoperative patients. Methods: The participants were randomly allocated to either the Difflam (n=22) group or the saline solution (n=23) group. The data were collected at the 1-, 4-, 7-, and 10-hour marks after returning to the ward post operation using the Beck's subjective oral discomfort scale, Visual Analogue Scale for sore throat, and portable halitosis detector. Results: The sore throat (F=7.25, p=.001) score significantly decreased after oral care using the Difflam spray 0.3%. However, the difference in the scores of oral comfort (F=0.34, p=.797) and halitosis (F=0.91, p=.443) between the two groups was not statistically significant. Conclusion: These findings suggest that the Difflam spray 0.3% is effective in improving postoperative sore throat. A further study that explores the effect of various oral solutions for postoperative patients is needed to present systemic and effective evidence-based oral care guidelines.

This study aimed to enhance the comfort of health masks by conducting in-depth interviews, online surveys, and wearing tests on commercial health masks. The findings are summarized below. In-depth interviews revealed that the most comfortable mask styles were ranked as follows: Beak-1 (B-1) & Beak-2 (B-2) style > Flat style > 3-Horizontal foldable (3H) style. Men generally preferred flat style masks, while women favored beak-shaped masks. The internet survey results showed that 77.8% of surveyed brands offered a variety of mask styles, with 3H and B-2 masks being the most common. Different brands provided masks with different filtration levels, ranging from KF-AD to KF94. Size consistency also varied among brands, with flat masks having relatively consistent dimensions and B-2 masks showing significant size differences. Wearing tests indicated that 3H and B-1 masks were highly satisfying for categories like "itchiness," "unpleasant odor," and "mask slipping." Conversely, flat masks scored the highest satisfaction in classifications such as "stiff," "heavy," "thick," "hot while wearing it," "moisture accumulation," "breathing discomfort," "short ear straps," and "itchiness". Overall, the flat style, B-1, and B-2 yielded higher satisfaction levels, while 4-Horizontal foldable (4H) and 3H garnered lower satisfaction scores on wearing tests.

Korea has already entered into an aging society. In recent decades, the health problems for seniors has received considerable interest. We often see the elderly who have been struggled from discomfort or illness of the foot. Those foot related problems mainly cause from the use of improper shoes. Recently, shoe makers sell the shoes for seniors, so called comfort shoes, but the shoes are too expensive for seniors to buy easily. In this paper, we develop cheap insoles for seniors as an alternative of the comfort shoes and suggest the systematic process for the insoles development. This systematic process is as follows: 1) Survey the literature about the market of insole, 2) Investigate the standard size of body and foot for the seniors in Korea, 3) Analyze the customer needs by survey, 4) Study the walking pattern by experiments, and 5) Develop the novel insole for the seniors to relieve the inconveniences related with foot. From the newly developed insoles, the company B gains the sales increasing effect approximately 30% over through the increase in consumer satisfaction and company reputation and secures for intellectual property rights. Using the database from Korea Research Institute of Standards and Science, the reliability of developing technology of the functional insole has been obtained. The seniors are also enable to choose an alternative of comfort shoes for foot health. In the future, the insoles developed from this study have wide applications in the medical, cosmetic fields, and leisure sports fields. Accordingly, it seems to require more systematic studies utilizing Walk Analyzer and Foot Pressure Meter.

Excessive acceleration experienced at the top floors in a building during wind storms affect the serviceability of the building with respect to occupant comfort and discomfort. Tuned liquid damper (TLD) and multiple tuned liquid damper (MTLD), which are passive control devices consisting of a rigid tank filled with liquid, are used to suppress vibration of structures. These TLD and MTLD offer several potential advantages-low costs, easy installation in existing structures and effectiveness even for small-amplitude vibrations. This study carries out a theoretical estimation of the most effective damping ratios that can be achieved by TLD and MTLD. Damping by TLD an MTLD reduced the frequency response of high-rise buildings by approximately 40% in urban and suburban areas.

MMinimally invasive surgery (MIS) for early stage lung cancer has been an important treatment modality. However, the ergonomic discomfort and counterintuitive instruments hindered the application of video-assisted thoracic surgery (VATS) to more advanced procedures. To improve the compliance with MIS, robotic surgery was adopted. This advance aimed to alleviate the shortcomings of VATS by maximizing the comfort of the surgeon while providing instruments that enabled technically demanding operations and three-dimensional views with increased freedom for intrathoracic movement owing to EndoWrist$^{(R)}$. In this session, we introduced the clinical applications and its results of robot-assisted thoracic surgery in the field of lung cancer surgery. In conclusion, robot-assisted pulmonary resection with lymph node dissection for lung cancer is safe as well as feasible, and it results in a satisfying postoperative outcome. Robot-assisted surgery may provide a good alternative to conventional open or thoracoscopic surgery for lung cancer, provided that the cost effectiveness and long-term prognosis are confirmed.

This is a basic study designed to discover the most comfortable thermal environment for Korean residences. The purpose of the research is to observe and measure the summer thermal environment in Korean urban detached single family houses and apartments by utilising proposed evaluation standards and methods. The technique used involves the measurement of environmental elements, such as indoor temperature, relative humidity and radiant temperature both in detached single family houses and apartments. Also, in order to understand the resident's thermal comfort response. ASHRAE' thermal sensation 9th level, indoor temperature 5th level, and thermal discomfort 4th level in the psycho-physical voting scale (1972) was used. In conclusion, among Korean urban residences, detached single family houses provided a more stable thermal environment than apartments, as shown by physical psychological evaluations. The possible reason for such stability in detached single family houses may be the usage of reinforced concrete structures which maintain consistent temperatures.
