  • This study was conducted to examine the influence and effect of muscle enforcement program on Activity of daily living(ADL) improvement and posture balance of the old, and to provide more effective muscle enforcement program and educational data. The muscle enforcement exercise program was performed on the old(institution, 16 men, 10 women) for 8 weeks from April 22, 2002 through June 17,2002. Programed Exercise 1 - Exercise 10 were practised 8 times per program for 3 days a week. The load of exercise was increased per two weeks. The methods of measurement were questionnaire, Indiana 47903(action-response analysis machine) and Sample exercise protocol for KAT 2000(balance training device). SAS/PC statistic analysis was used for data analysis. T-test was used for analysis of change before and after exercise in this study. The summary and conclusions are as follows. 1. On subjectively recognized health states, the healthy were $42.3\%$. On the satisfaction with health states, the satisfied were $50.0\%$. On the factors of effects on daily-life behavior performance, the group who had troubles was $50\%$ and the group who was so and so was $34.6\%$ compared with the old of the same age. On prospect about health states in the future, the group who would be better was $38.\%$. On effective methods for problem solving, exercise was $42.3\%.\;88.5\%$ of respondents answered the need of health care. The participation intention in health program was $92.3\%$. 2. On the change of psychological emotion and behavior aspects, the group who had repeated complaints or anxieties and reduced activities or interests was effective(P<0.01). 3. On the improvement effects of IADL difficulties, the group who had difficulties in doing daily-life indoors was improved effectively compared with before and after exercise(P<0.01). On medication management, the effects of improvement after exercise were high compared with before exercise(P<0.01), the effects of improvement was high on the whole. 4. On the effects of ADL function improvement, putting on upper clothing and lower clothing was improved effectively(P<0.05), toilet use and individual sanitation was improved effectively(P<0.05). 5. On the effects of action-response, the results of 8weeks regular exercise program were not different significantly compared with before and after exercise. The behavior quickness of the old by muscle enforcement program was not increased. This means that the old needs much time for exercise sense training because of the regression of cognition sense. 6. In the effect of posture balance, the whole grades were effective from 1272.69 before excercise to 476.92 after exercise(P<0.01). Especially right balance 657.65 was lowered to 208.57 after exercise most effectively(P<0.01). Rear balance 776.34 before exercise was lowered to 136.65 after exercise. The results of measurement were significant(P<0.05).

  • TThis study explored the requirement of fabric sensor that can measure the motion of the joint effectively by measuring and analyzing the variation in electric resistance of a sensor in accordance with bending and stretching motion of the arm by the implementation of a motion sensor utilizing conductive fabric. For this purpose, on both sides of two kinds of knitted fabric, namely 'L' fabric and 'W' fabric Single Wall Carbon Nano-Tube(SWCNT) was coated, fabric sensor was developed by finishing them in a variety of ways, and the sensor was attached to the arm band. The fabric sensor consisted of total 48 cases, namely background fabric for coating, the method of sensor attachment, the number of layer of sensors, the length of sensor, and the width of sensor. The performance of fabric motion sensors in terms of a dummy arm, that is, a Con-Trex MJ with 48 arm bands around it was evaluated. For each arm band, a total of 48, fastened around the dummy arm, it was adjusted to repeat the bending and stretching at the frequency : 0.5Hz, ROM : $20^{\circ}{\sim}120^{\circ}$, the voltage was recorded for each case after conducting three sets of repeat measurement for a total of 48 cases. As a result of the experiment, and as a consequences of the evaluation and analysis of the voltage based on the uniformity of the base line of the peak-to-peak voltage(Vp-p), the uniformity of Vp-p within the same set, and the uniformity of the Vp-p among three sets, the fabric sensors that have been configured in SWCNT coated 'L' fabric / welding / two layers / $50{\times}5mm$, $50{\times}10mm$, $100{\times}10mm$, and SWCNT coated 'W' fabric / welding / two layers / $50{\times}10mm$ exhibited the most uniform and stable signal value within 5% of the total variation rate. Through all these results of the experiment, it was confirmed that SWCNT coated fabric was suitable for a sensor that can measure the human limb operation when it was implemented as a fabric sensor in a variety of forms, and the optimal sensor types were identified.

  • Uncanny valley refers to the condition where the affinity of a human-like object decreases dramatically if the object becomes extremely similar to human, and has been hypothesized to derive from the cognitive load of categorical conflict against an uncanny object. According to the hypothesis, the present study ran an oddball task consisting of trials each displaying one among a non-human, human and uncanny face, and measured event-related potentials (ERPs) for each trial condition. In Experiment 1, a non-human face was presented in 80% of the trials (standard) whereas a human face for another 10% trials (target) and an uncanny face for the remaining 10% trials (uncanny). Participants' responses were relatively inaccurate and delayed in both the target and uncanny oddball trials, but neither P3 nor N170 component differed across the three trial conditions. Experiment 2 used 3-D rendered realistic faces to increase the degree of categorical conflict, and found the behavioral results were similar to Experiment 1. However, the peak amplitude of N170 of the target and uncanny trials were higher than the standard trials while P3 mean amplitudes for both the target and uncanny trials were comparable but higher than the amplitude for the standard trials. P3 latencies were delayed in the order of the standard, target, and uncanny trials. The changes in N170 and P3 patterns across the experiments appear to arise from the categorical conflict that the uncanny face must be categorized as a non-target according to the oddball-task requirement despite its perceived category of a human face. The observed increase of cognitive load following the added reality to the uncanny face also indicates that the cognitive load, supposedly responsible for the uncanny experience, would depend on the increase of categorical conflict information subsequent to added stimulus complexity.

  • The purpose of this study was to investigate the effects of three kinds of horticultural activities (HAs) on attention concentration of elementary students. We selected 20 students using a Wee Class counseling office at J elementary school in Yeongcheon, and divided them into experimental and control groups composed of ten students each. The experimental group participated in three HAs including flower arrangement, planting, and pressed flower. Each HA was composed of three sessions and a session proceeded for a week. For the examinations of attention concentration, two groups responded the questionnaires before a week of the first session and at the end of the 9th session, only the experimental group participated in the measurement using grid by Harris before a week of the first session and at the end of each HA every week. The results of questionnaire survey showed that the scores of problem in emotion and problem in controlling, and the total score decreased 9.2, 7.8, and 19.0 points, respectively (P < 0.05), indicating that the attention concentration of the experimental group improved compared with the control. In the measurements using grid by Harris, the flower arrangement, planting, and pressed flower activities increased the scores by 2.22, 2.49, and 2.41 points compared with the pre-HA of 6.00, respectively (P < 0.05), that means the improvements of attention concentration. At the post-HAs, the flower arrangement, planting, and pressed flower activities increased the scores by 1.12, 1.39 and 1.31 points compared with the control group of 7.10, respectively (P < 0.05). In conclusion, the indoor HAs improved the attention and concentration of elementary students irrespective of kind of activities.

  • This study is aimed to inspect how the different sensitivities in Behavioral activation system(BAS) and behavioral inhibition system(BIS) modulate on the properties of physiological responses stimulated by positive or negative affective sound. We measured the electroencephalogram(EEG) and electrocardiogram (ECG) of 32 students, consisted of four groups depending on the BAS and BIS sensitivities, during listening to meditation music or noise. The EEG was recorded at Fpl and Fp2 sites and Power spectral density(PSD) of HRV was derived from the ECG, and the power of HRV was calculated for 3 major frequency ranges(low frequency[LF], medium frequency and high frequency[HF]). After listening to music or noise, subjects reported the affect induced by the sound. For EEG, the power in the alpha band at Fp2, especially in the alpha-2 band(9.0-11.0 Hz) increased during the subjects listening to music, while the power at Fpl increased during noise. During listening to meditation music, there is a tendency that the left-sided activation in prefrontal cortex(PFC) is positively correlated with the difference of BAS(Z)-BIS(Z). During listening to noise, there is a tendency that the right-sided activation in PFC is dominant in case any of the sensitivity of BAS or BIS is high. For HRV, we found that the index of MF/(LF+HF), during listening to music, was higher significantly in the individuals with a low BIS but high BAS than in the individuals with a low sensitivity both BIS and BAS individuals. With high BIS, regardless of the BAS sensitivity, the difference of this index values was not significant. From these results we suggest that the physiological responses of different individuals in BAS and BIS react differently under the same emotionally provocative challenge.

  • The purpose of this study is to develop a strain sensor based on a nanoweb by applying electrical conductivity to a polyurethane nanoweb through the use of Graphene. For this purpose, 1% Graphene ink was pour-coated on a polyurethane nanoweb and post-treated with PDMS (Polydimethylsiloxane) to complete a wearable strain sensor. The surface characteristics of the specimens were evaluated using a field emission scanning electron microscope (FE-SEM) to check whether the conductive material was well coated on the surface of the specimen. Electrical properties of the specimens were measured by using a multimeter to measure the linear resistance of the specimen and comparing how the line resistance changes when 5% and 10% of the specimens are tensioned, respectively. In order to evaluate the performance of the specimen, the gauge factor was obtained. The evaluation of the clothing was performed by attaching the completed strain sensor to the dummy and measuring the respiration signal according to the tension using MP150 (Biopac system Inc., USA) and Acqknowledge (ver. 4.2, Biopac system Inc., U.S.A.). As a result of the evaluation of the surface characteristics, it was confirmed that all the conductive nanoweb specimen were uniformly coated with the Graphen ink. As a result of measuring the resistance value according to the tensile strength, the specimen G, which was treated with just graphene had the lowest resistance value, the specimen G-H had the highest resistance value, and the change of the line resistance value of the specimen G and the specimen G-H is increased to 5% It is found that it increases steadily. Unlike the resistance value results, specimen G showed a higher gauge rate than specimen G-H. As a result of evaluation of the actual clothes, the strain sensor made using the specimen G-H measured the stable peak value and obtained a signal of good quality. Therefore, we confirmed that the polyurethane nanoweb treated with Graphene ink plays a role as a breathing sensor.

  • Purpose: Firefighters were subjected to be exposed to 24-hour shiftwork and high level of job stress, but there is little study of fire fighters about between Job Stress and Psychological stress in Korea. This study was performed to evaluate job stress of fire fighters grouped by different job types and analyze the health effect of job stress by using a PWI-SF(Psycho-social Well-being Index, Short Form). Methods : This study was to measure the degree of job stress and socio-psychological stress of firefighters working at 119 safety center and analyze the relationship between job stress and mental health, through self-administered questionnaire survey on 918 fire fighters working at fire department located in Korea, during October in 2008. Question items of the questionnaire consist of general characteristics, job stress, and socio-psychological stress. Job Stress Measurement Scale for Koreans was used to measure job stress, while PWI-SF used for socio-psychological stress. Collected data was analyzed through frequency analysis, ${\chi}^2$ test, one-way ANOVA, correlation analysis, multi-regression analysis using a statistic program, SPSS/10.0 Ver for Windows, and statistical significance level was 0.05. Result : Accordingly, this paper is written for the purpose of scrutinizing the reason of 119 rescuers' job stress and Socio-Psychological stress. This thesis tries to analyze a problem and provide contents through many variables concerned and theoretical investigation with the actual research of questionnaire. The results of the study are summarized as follows : Fire fighters feel relatively high stressful in their performance. Job stress, organizational commitment and burnout did not have been influence upon by individual cases such as economic condition, regular exercise etc. Finally, as a result of step by step regression analysis, the variable that can explain Socio-Psychological stress the best was negative emotion scale(NE). Conclusions : It is necessary to conduct repeated studies in the future, since the study implied that there was a contrary relationship between job stress and socio-psychological stress. In order to reduce job stress and maintain better mental health, it is more important than anything else to help firefighters have willingness and efforts to sustain a healthy life, so the development of various programs and education to raise their awareness should be implemented.

  • When the crucial role of the agent in communicating with the customer is acknowledged well enough to relieve the agent's stress, it will lead to the decrease of the agent's emotional labor and the improvement of the business organization's performance simultaneously. However, the research on the relationship between information system and the emotional labor has been scarcely conducted even though the importance of the emotional labor is actively researched and discussed these days. Therefore, much effort has been put in this study to fine out how the quality of airline call center information system affects expectations-conformation and how expectations-conformation and self-efficacy affect performance of Emotional Labors. Analysis of the results to target a call center agent 436 people, When you provide them with quality information systems, it increased satisfaction and pride in their job. This mechanisms subsequently reduces the strength of the emotion labor, which ultimately improves the service performance. The implications of this study can be summarized as following: First, this research presented practical guidelines to the organization's decision-makers related to the airline call center operations in order to introduce and expand successful call center information system. Second, this research suggested the possible method to inspect and diagnose the system by way of applying the measurement model mentioned in this research into the airline information system and analyzing it. Third, the performance-measuring model developed in order to measure the performance of the airline call center information system can also be used when we carry out the performance-measuring task in the similar information system as the basis of diagnosing the situation and presenting the driving directions.

  • This study was designed to develop a program for unemployed matriarchs and show if the program affected their view on the meaning in life. The subjects were women registered in an occupational training program for unemployed matriarchs, which is being practiced in the 'Working Women Center' located in Busan. The researchers selected 44 persons from the group who agreed to our program. This study was done from the 10th of March, 1999 to the 9th of October. The researchers used the measurement tools, The Purpose in Life, Self-esteem, Hope and Meaning in Life which was composed of 63 items developed by them. Their Cronbach's alpha were .88, .79, .76 and .95. The researchers analyzed the data with frequency, percentage, Mean, S.D, Wilcoxon signed ranks test which were deduced from SPSS 10.0 WIN program. The results of this study were as follows: 1) The program is composed of 'becoming intimate', 'open-minded', 'exploration on self', 'relax of repressed emotion', 'self- acceptance', 'establishing the life-goal', 'enrichment of human relationship' and closing. It took 20 hours for this program to come into practice. 2) According to the analysis of the general traits of all subjects, average age was 39.36. High school graduates were 86%, college graduates were 14% and divorce were 57%, bereavement were 18%, and the rest were 25%. 3) The result of 1st progam showed self-esteem during the program was high. 4) The result of 2nd progam showed self-esteem during the program was high. 5) The result of 3rd progam showed the sum scores of meaning in life, creative meaning, and attitudinal meaning during the program was high. 6) The result of 4th progam showed the sum scores of meaning in life and creative meaning during the program was high. On the viewpoint of above results, we convinced that 'a program for unemployed matriarch is effective to establish a stronger meaning in life. Therefore, it is demanded that support for unemployed matriarchs should not only be economic help such as technical training and help of living expenses, but also psychological, professional and systematic support.

  • Vintage fashion is a lot influenced by colors because an emotion is transmitted via images of "old feeling", "worn-out feeling" and "faded feeling" etc. Colors are visual sensation occurring at a time when lights stimulate an eye, which is a representative factor which humans first perceive when they touch objects. And colors in clothing function as a critical element which indicates an individual's impression and character as well as aesthetic sensation. In this study, I examined on the theoretical consideration and aesthetic characteristics via the previous literature on vintage fashion and colors. As an empirical study, I investigated on the colors of vintage fashion appearing in Pr$\hat{e}$t-$\grave{a}$-porter Collections, Paris from Spring/Summer, 2003 to Fall/Winter 2008. As a way for study, I investigated into the total 197 vintage fashion photos and calculated their RGB values by using photoshop. And I converted the values of the colors extracted into H V/C values by using Munsell Conversion Version 9.0.6 and analyzed on Munsell System of 10 Color Notation and the PCCS colors, classifying a color scheme by visual sensation measurement. The result of analyzing on the concept of vintage fashion and its color characteristics is as follows; Vintage fashion made an appearance the most in 2003 and 2004 and its colors appeared a lot in Y, YR, R and PB lines. Color tone concentrated on black and white, achromatic color and low chroma colors in a grayish line, chromatic color. Thus, the study found that colors suitable for a "worn-out", "faded" and "old" image are properly reflected in vintage fashion rather than a clear and bright background. In a color scheme, I found contrast color and same color appearing a lot, which gave an unharmonious feeling and a smack of the country. The study reveals that the color characteristic of vintage fashion is relatively diverse and complex in color, color tone or shade and color scheme, which shows a color trend which reflects a non-constructive and complex coordination characteristic instead of a standardized simple and clear image.
