In order to study the role of legato to singers in vocal music performance, this paper adopts the methods of demonstration and induction and comparison to analyze the three factors affecting the creation of legato in performance and propose solutions. When thinking about the influence of singing skills on legato, singers will be able to solve such issues as breathing, articulation and vocal register, thus improving their singing skills. When thinking about the influence of singing language on legato, singers will make an in-depth study on the phonetic and structural features of the language to reach legato in language, thus promoting the in-depth study of singers on the singing language. When thinking about the influence of singing emotion on legato, singers will solve the problem of emotional coherence from two aspects of thought and emotion to create legato of emotion, thus promoting the expression of singers' emotion in the work. Obviously, legato plays an important role in improving singers' singing skills, singing language and singing emotion. The aim of the paper is to encourage singers to further deepen their attention to legato in vocal music performance and make better use of legato in singing.

Most of manufacturers try to produce the most efficient filter for respirators with the lowest breathing resistance. Filter performance depends on low penetration, i.e., high efficiency (%), and low pressure drop ($mmH_2O$). This study was performed to evaluate performance of respirator filters by quality factor ($q_F$) and suggest the direction for improvement of respirator filters of good quality in Korea. Two mechanical filters, S and K made in Korea, three filtering facepieces, S made in China, C made in Korea and M made in USA, which were widely used in the workplace, were selected and tested efficiency and pressure drop in accordance with flow rate, using with Automated Filter Tester Model 8110 (TSI, USA). The best quality factor within the same respirator filter categories was $0.0672cm^{-1}\;H_2O$ for mechanical filter S, $0.0698cm^{-1}\;H_2O$ for filtering facepiece M at flow rate of 32Lpm. Mechanical filter S would be the best suitable during heavy work since qulity factors decrease less sharply than any others as increased flow rates. It was necessary for mechanical filter S to lower pressure drop without increasing efficiency, but mechanical filter K should be increased efficiency and decreased pressure drop. While filtering facepiece M had the best quality performance of three ones, Sand C should get much higher efficiency and lower pressure for better performance.

This study investigated hospital EMT' scope of work perceived by emergency medical service providers by surveying 122 emergency medical service providers working at university hospitals in Daejeon and Chung-nam in order to provide basic materials for improving EMT' roles and legal regulations related to their works and enhancing the quality of emergency medical services. According to the results of this study was $3.23{\pm}0.67$ for the 40 items surveyed, which was somewhat higher than average. By area, job awareness was highest for trauma care, which was followed by hospital phase and breathing assistance, and lowest for medication. In order for emergency medical service providers to recognize hospital EMT' works, first of all, EMT need to carry out their jobs and roles faithfully. Therefore, educational institutions should provide substantial education programs. What is more, legally clear definitions should be made on the job of EMT, and campaigns and monitoring should be made continuously for EMT.

Mental health is attributed to person's well-being, abilities and productivity. The purpose of this study is to suggest the effects of K-culture to people in adversity. It is PungmulPanGut, represented by traditional Korean play culture. Pungmul is a performance with four percussion instruments, Janggu (Korean hourglass drum), Buk (barrel shaped drum), Jing (large gong), Kkwaenggwari (small gong), and play. In Korean, "pan" means that it's a place to do something. Gut means to make a wish. The ensemble Better Than Medicine (eBTM) is a team that has trained and worked with Gamuak (歌,舞,樂; singing, dancing, playing) for a long time, but is not perfect (we refer this as 2% lacking in music). The characteristic of our team is that we share joy while voluntarily participating and doing what we like. It is a combination of singing, dancing, playing musical instruments, and exciting people. There is wind-like energy and there is mutual cooperation, not competition. As we concentrate, we become immersed in each other's breathing and movement. So it makes us forget the hard situation, the hardships, the pain, and so on. In the meantime, our pleasures peak and share happy energy with each other. Even though we are two percent less skilled, our sense of happiness doubles. Music together is not competition but cooperative work and healing. Therefore, we suggest that PungmulPanGut can be better K-culture than medicine in promoting mental health.

The purpose of this research is to investigate appropriate usage of pansori's method of breathing, sound making, and resonance in order to develop actor's aesthetic voice. Today's theatre no longer see inter-cultural approach as new or experimental, but see it as a part of global current. Actors are required to integrate some global-ness into their acting. It's not enough, however, for actors to equip some cosmopolitan sensibility. More important thing is that they should be able to integrate one's own culture and aesthetic into their performance. Only after acquiring one's own cultural identity, it is possible to step into inter-cultural work. It is fundamental, therefore, for actors to assimilate traditional movement and aesthetic voice. It's been known that traditional Korean voice traits are well preserved in Pansori. In this paper, based upon well-known theories and practices of western voice training, pansori's principles and practices are utilized to bring a new aesthetic voice.

This study applied ALOHA Program to predict the damage caused by fire and explosion predicted to occur from gas leakage at LPG stations and presented plans to prevent damages by diagramming the impact range and distance. The propane gas leakage from LPG stations causes human damage like breathing issues and property damage, including building destruction to residents in the surrounding areas. As a way to reduce this, first, the hazardous substance safety manager of the LPG station needs to check frequently whether the meters and safety valves are working properly to prevent leakage in advance. Second, the LPG stations' storage tanks should be worked by the person who received "hazardous substance safety manager training" under the provisions of the Act on the Safety Control of Hazardous Substances and has been appointed as a "hazardous substance safety manager" by the fire department. Third, LPG station's various safety device functions, such as overfill prevention devices, must be checked on a regular basis. Finally, wearing work clothes and shoes that prevent static electricity at LPG stations is highly recommended, as static can cause a fire when gas leaks.

The purpose of this study was to investigate the stress response of nurses working on psychiatric wards (psychiatric nurses) compared with that of nurses working on general wards (general nurses) in order to provide assessment data for intervention of the stress response. The Symptoms of Stress Inventory was used to measure the stress response. Data were collected by a direct survey method using a questionnaire and were collected from March first to March 30, 1995. A sample of 200 nurses working in three psychiatric hospitals and psychiatric wards in four university hospitals in Seoul and Kangwon province were selected and 200 nurses working on general wards from two general hospitals in Seoul were also selected for a total sample of 400 nurses. Nurses who had experienced more than one of the major life events in the last two years were excluded from the total number in the samples, so the final sample was 161 psychiatric nurses, and 169 general nurses. The Scores for the total stress response, scores of the SOS subscales, stress response by sociodemographic characteristics of the nurses working on the psychiatric wards were compared with those of nurses working on the general ward. The results of this investigation are as follows 1. The mean total SOS score for the psychiatric nurse was 0.81 (SD=0.48) and that of the general nurses was 0.90(SD=0.53). 2. The Mean score for peripheral manifestation, con tral-neurological symptoms, gastrointestinal symptoms, muscle tension, habitual patterns, de-pression, anxiety, anger and cognitive disorganization for the general nurses showed a tendency to be higher than those of the psychiatric nurses. Mean score for cardiopulmonary symptoms for the general nurses was significantly higher than that of the psychiatric nurses. 3. The mean scores for the sixteen SOS items for the general nurses was significantly higher than for the psychiatric nurses. The 16 items were flushing of the face, sweating excessively even in cold weather, thumping of the heart, rapid breathing, dry mouth, a choking lump in the throat, hoarseness, muscle tension in hands or arm, muscle tension in leg, working tiring one out completely, severe aches a핀 Pain make it diffi-cult to do the work, severe nervous exhaustion, worrying about health, feeling weak and faint, so upset that one wants to hit something, unable to keep thoughts from running through one's mind. The mean score of only 505 item were significantly higher for the psychiatric nurses. 4. Stress responses between psychiatric nurses and general nurses were significantly different according to the following demographic characteristics : marriage, duration of work, position, accommodation, planning to move into another working site, working ward, education in psychiatric nursing.

Background: A tobacco-free workplace policy is identified as an effective means to reduce tobacco use and protect people from second-hand smoke; however, the number of tobacco-free policies (TFP) remains very low in workplaces in Malaysia. This study explored the factors affecting support for a tobacco-free policy on two healthcare campuses in Malaysia, prior to the implementation of TFP. Materials and Methods: This cross-sectional study was conducted among 286 non-smokers from two healthcare training centres and two nearby colleges in Malaysia from January 2015 to April 2015. A standardized questionnaire was administered via staff and student emails. The questionnaire collected information on sociodemographic characteristics, support for a tobacco-free policy and perceived respiratory and sensory symptoms due to tobacco exposure. Bivariate and multivariate logistic regression analyses were performed to estimate the independent effects of supporting a tobacco-free campus. Results: The percentage of individuals supporting completely tobacco-free facilities was 83.2% (N=238), as opposed to 16.7% (N=48) in support of partially tobacco-free facilities. Compared to the supporters of partially tobacco-free facilities, non-smokers who supported completely tobacco-free health facilities were more likely to be female, have higher education levels, to be very concerned about the effects of other people smoking on their health and to perceive a tobacco-free policy as very important. In addition, they perceived that tobacco smoke bothered them at work by causing headaches and coughs and, in the past 4 weeks, had experienced difficulty breathing. In the multivariate model, after adjusting for sociodemographic characteristics and other factors, only experiencing coughs and headaches increased the odds of supporting a completely tobacco-free campus, up to 2.5- and 1.9-fold, respectively. Conclusions: Coughs and headaches due to other people smoking at work enhances support for a completely tobacco-free campus among non-smokers.

In this study we have examined the health risk factors and analyzing data of laborers working at the welding operation at large-sized casting process. In order to improve the working environment of workplace, an effective ventilation method was proposed after performing CFD (computational fluid dynamics) modeling and measurement of pollutants. As a result of examining the health risk factors of workers, oxidized steel dust is the main pollution source in the company A, welding fume in the companies B and C, and welding fume and oxidized steel dust in the company D. The fume concentration in the workers' breathing zone was $0.05{\sim}4.37mg/m^3$, and the fume concentration in the indoor air at the welding process was $0.13{\sim}7.54mg/m^3$. From a result of CFD, a local exhaust with an exhaust duct adjacent to welding point was found to be most effective in case of the exhaust process. In case of air supply, we found that a desired location of air supply fan would be at the end of the opening. If a standardizing the ventilation system for tunnel-type semi-enclosed space at a large-sized casting process is introduced in welding work places in the future, it would be more effective to protect the health of welding workers working at the casting industry and shipbuilding industry and improve the work environment.
