  • This study attempted to compare usability of auditory interfaces, which is a comprehensive concept that includes safety, utility, effectiveness, and efficiency, in personal computing environments: verbal messages (speech sounds), earcons (musical sounds), and auditory icons (natural sounds). This study hypothesized that verbal messages would offer higher usability than earcons and auditory icons, since the verbal messages are easy to interpret and understand based on semiotic process. In this study, usability was measured by a set of seven items: ability to inform what the program is doing, relevance to visual interfaces, degree of stimulation, degree of understandability, perceived time pressure, clearness of sound outputs, and degrees of satisfaction. Through the experimental research, the results showed that verbal messages provided the highest level of usability. On the contrary, auditory icons showed the lowest level of usability, as they require users to establish new coding schemes, and thus demand more mental effort from users.

  • This study attempted to identify the entrance exam stress levels in high school students and analyze the relationship this entrance exam stress and perceived oral health status. Self-administered survey was conducted in total 304 students attending in academic high schools in Bucheon. For analysis, SPSS was used to perform t-test and one-way ANOVA. As a result of the study, the entrance exam stress level of academic high school students was 2.71. The level of sub-factors were that tension for exam/poor result was highest by 3.08 and the next were future uncertainty (2.81), parents pressure (2.56), and insufficient free time (2.52). The group with high entrance exam stress showed significantly high perceived degrees of temporomandibular disorder, oral mucosal disease and xerostama. Among sub-factors of stress, the group with high tension for exam/poor result stress had significantly high perceived degrees of dental caries, teporomandibular disorder, oral mucosal disease and xerostama. Because perception on oral health issues increased with high entrance exam stress in high school students, it is necessary to seek some ways to decrease oral health problems even though entrance exam stress is intensified. To do so, it is inferred that it will be very important to promote oral health education to develop ability of high school students to practice correct oral management method.

  • This study was conducted to evaluate the health promotion behavior level, health beliefs, and self-efficacy of individuals preparing for civil service examinations, as well as the main factors that influence their health promotion behavior. The study subjects were 290 individuals who were preparing for civil service examinations in Noryangjin, where there are a lot of private institutions that provide training for the examinations. Data were collected by questionnaire surveys conducted from December 1 to 19, 2017. With the use of SPSS ver. 23, descriptive statistics, t-tests, one-way ANOVA, correlation analysis, and stepwise multiple regression were conducted. On average, the score for health promotion behavior practice was $2.37{\pm}0.45points$, health beliefs $3.13{\pm}0.45points$, and self-efficacy $3.55{\pm}0.74points$. Health promotion behavior was significantly positively correlated with perceived severity and perceived benefits, which are sub factors of health beliefs (r=.60, p<.001; r=.55, p<.001), while it was significantly negatively correlated with perceived barriers, which are a sub factor of health beliefs (r=.32, p<.001). The factors that influenced health promotion behavior were perceived health condition and perceived barriers, and the explanatory power of health promotion behavior was 25.1% (F=13.58, p<.001). In general, respondents studied for the examinations for a long time and were under severe job pressure; accordingly, they need to have quality meals, regular exercise, and regular medical check-ups to enhance health promotion behavior to control their stress.

  • Various characteristics of the object being lifted are known to affect the biomechanical, physiological, and psychophysical stresses. The object characteristics to be considered in the design process of lifting tasks are weight, shape, stiffness, and availability of handles and similar coupling devices. In this study, a prototype Polypropylene laminated bag with carrying handles was designed to decrease the physical stress of people who handle these bags. Physiological and psychophysical approaches as well as subjective ratings were applied to evaluate the effects of handles provided on the designed PP laminated bag. Statistical analysis showed that the VO2, heart rate, blood pressure, and Borg-RPE score for PP laminated fertilizer bag with carrying handles were significantly lower than those bags without handles. Moreover, Maximum Acceptable Lifting Endurance Time(MALET) measure, newly developed in this study, for bags with handles was significantly higher than those for bags without handles. It is thus recommended that the various types of bags and boxes be equipped with handles to reduce the musculoskeletal, physiological, psychophysical, and subjective perceived stresses.

  • Exercises are achievement oriented, the process is frequently perceived as hard and difficult Participants drop out from exercise programs in the middle of the training period. Dance movement, which is the deliberate and systematic use of movement, is enjoyable during the movement and provides opportunities for persons to express them-selves. Regular long term dance movement may in-duce a training effect with a decreased drop out rate. Dance movement could be one way to attain wellness, however, there have been few studies to evaluate both physiological and psychological aspects of dance movement. This study focused on evaluating the effects of dance movement training on body weight, resting blood pressure and heart rate, limb circumference and strength, stress response and subjective feelings. This quasi-experimental study was designed as a nonequivalent control group pre test -post test study. Ten healthy fe-male subjects, aged between 19 and 31 years volunteered for an eight week dance movement program. Ten healthy female subjects, between 19 and 21 years of age paticipated as controls. None of the subjects had performed regular physical activity for six months prior to the study. Dance movement was created with reference to Heber's movement guide. The Dance movement program consisted of approximately 30 minutes of dance, three days per week, for eight weeks. During each 30 minute work out, there were approximately 5 minutes of warm-up dancing, 20 minutes of conditioning dance and 5 minutes of cool-down dancing. The intensity for the conditioning phase was at between 60% and 65% of age-adjusted maximum heart rates. Body weight, resting blood pressure and heart rate, circumference of mid upper arm, mid thigh and mid calf, muscle strength of upper and lower limb, physical and psychological response to stress were measured prior to, and following the experimental treatment. Body weight was measured by digital weight scale(Kyung In Corp., Korea). Resting systolic and diastolic blood pressure were measured by sphygmomanometer, Resting heart rate was measured for one minute in a relaxed sitting position using the radial artery. Circumference of mid upper arm, mid thigh and mid calf was determined by tape measure. Muscle strength of the upper extremities was measured by a grip dynamometer (Takei Corp. No.1857, Japan) and that of the extremities was measured by the length of time the leg could be held at 45° Physical and psychological responses to stress were measured using the Symptoms of Stress (SOS)Scale. Paticipants in the dance movement were interviewed by the facilitator following the eight weeks, and their thematic responses about the dance movement were recorded. Following the eight week dance movement train-ing, body weight decreased significantly, circumference of mid thigh and mid calf increased. The length of time leg - raising could be held tended to increase following the dance movement training. Resting systolic and resting heart rate showed a tendency to decrease. Total mean score of stress response tended to de-crease, and mean score of habitual patterns, do-pression, anxiety / fear, anger and cognitive disorganization decreased remarkably following the eight week dance movement. Thematic responses about the dance movement were positive following the training.

  • Young black men(YBM) have the most severs levels of high blood pressure(HBP) and, in all reports but one, the lowest of HBP control of any age /sex /race group. To increase entry into care, remaining in care, and BP control for young(18-49 years) Black men, It is needed to review socio-demographic, medical characteristics, and behaviors(importance of and difficulty with HBP control behaviors, or worry about mdication) for experimental intervention study(educational- behavior strategies) of hypertensive urban young black men. The 204 participants had an average age of 38.8+7.0 years and an average educational level of $11.0{\pm}2.4$ years; only 23.1% were employed full- or part-time while 26% were on disability ; and 6% were married. Only 35.3% had an MD for HBP care and 37.3% had some form of health insurance. The average BP of those men currently being in care on medication(35.3%) was $148.2/95.1{\pm}19.5/11.3$ compared to those men not taking HBP care $153.7/99.1{\pm}14.0/9.8(p<.05)$. The average creatinine level was 1.3(excluding 3 marked elevations of 15.9, 9.6, and 7.7) for the 163 men consenting to have their blood drawn. Self-reported co-morbidity induded heart disease 7.8%, diabetes 8.9%, high cholesterol 18.2%, CVA 3.4%, alcohol and drug related problems 27.9% and 22.5% respectively. The kidney disease of those men currently being in care & on medication was 9.7 compared to those men not taking HBP care 0.8(p<.05). The problems of with sex life, physicl activity and dearly thinking of those men currently being in care & on medication was higher compared to those men not taking HBP care(p<.05). Questions of 'during the past month, on how many days did you have 5 or more drinks (bottles) of any alcoholic beverag?' and smoking of those men currently being in care & on medication was 18.1% and 72.2% compared to those men not taking HBP care 27.3 and 82.6%, respectively. HBP control behaviors was assessed with 1-5 point Likert subscales(5=extreme, 1-none at all), In general, th men reportd low levels of perceived psychological barrier to HBP care and control behaviors; importance of and difficulty with HBP control behaviors, or worry about mdication. For example, on a five point scale(1=none at all, 5=extreme), average ratings for perceived important and difficulty with BP care and behaviors were 2.8(SD=1.2) and 2.5(SD=1.1). Average ratings for perceived benefit with BP care and behaviors worry about medication of those men currently being in care on medication was 4.0(SD=0.9) and 2.2(SD=1.1) compared to those men not taking HBP care 3.6(SD=0.8), 2.8 (SD=1.6) respectively(p<.05). These data support the need for educational-behavioral strategies of community health nurse to improve high blood pressure control in this high risk group through perceived barriers to treatment, health care skills and use of resources, and social support.

  • According to introduction of Well-Being lifestyle and ageing society, vital sign monitoring system which can be continued measurement of vital sign has been increased their important in field of the healthcare. Under this trend, Respiration monitoring system has been studied and developed in a various way to apply continued monitoring and non-conscious monitoring system. But, Study of the respiration monitoring system based on consumer needs and usability test is insufficient. In this study, Textile capacitive pressure sensor(TCPS) of belt type was developed and tested it's utility and subjective sensibility. TCPS measures respiration signals and can be derived in real time monitoring. As a result, monitoring respiration using textile capacitive pressure sensor offers a promising possibility of convenient measurement of respiration rate (correlation (r=0.9553, p<0.0001). In the result of usability and wearability test, all of categorizes(perceived change, wearability, movement, facility of management, usefulness) were received favorable evaluation on usability test( mean value : 3.8), and suitable location of TCPS in the clothing is deriven on the abdomen part. According to synthetical results, Basic smart clothing design based on respiration monitoring system is proposed.
