The phonemic awareness program included construction of 45 activities emphasizing various sounds in speech and letter names using a storybook. The subjects were thirty 1st and 2nd grade low-income(15 experimental and 15 control group) children attending an after-school program in Seoul. Pre- and post-tests assessed children's reading, self-concept, and learning motivation. The experimental group children had rich opportunity to deal with and discuss sounds, syllables, phonemes, and the Korean alphabet names during storybook reading, games, and play over a 12 week period, while the control group children were provided with worksheets, subject tutoring, and homework guidance. Results showed that the phonemic activities were an effective and useful way to enhance children's reading ability, self-concept, and learning motivation.

Coping patterns were investigated in a sample of 126 patients with chronic low back pain by means of self-reported questionnaire. Based on the previous researches, coping pat terns were divided into the active cognitive coping, the active behavioral coping, the passive cognitive coping, and the passive behavioral coping. While all the above coping patterns were used, the passive behavioral coping was found to be used most frequently. Six subgroups were identified by cluster analytic procedure using their scores of the coping scale : active cognitive coper, general active coper, passive behavioral coper, general passive coper, multidimensional coper, and multi dimensional non-coper. Six subgroups were compared regarding locus of control, self-efficacy, pain and demographic variables. Distinct differences appeared among subgroups in internal locus of control, self-efficacy, and pain. General active coper and active cognitive coper had higher internal locus of control, higher self-efficacy, and lower pain. General passive coper and multidimensional non-coper had lower internal locus of control, lower self-efficacy, and higher pain. Passive behavioral coper had higher internal locus of control, lower self-efficacy, and higher pain. It supports the concept of learned helplessness due to prior experiences. Multi dimensional coper had higher internal, higher powerful others, and higher self-efficacy. So it corresponds to 'believer in control' group Identified by Wallston et at(1982). Unexpectedly this group also complained more pain. It could be interpreted in two ways. The more coping methods they use, the more they complain pain ; which is the result of Folkman et al (1986). Or they might be typical 'yea sayers'. These unique groups-passive behavioral coper and multidimensional coper-identified by this study supports the suggestion of Wallston et al(1982), about locus of control : individual's pattern of responses across the three scales may be more predictive than his or her scores on each of the scale seperately. The fact that passive coping was used more than active coping also suggests that self controlled active co ping is encouraged to chronic patients as well as acute patients. And it is necessary to articulate the coping scale and self-efficacy scale. It is also necessary to study the relationship of coping and adjustment by experimental design.

Tension and self-control are explanatory factors in adolescent delinquency, and internet addiction and anonymity are regarded as factors underlying cyber deviation. The aim of this study was to investigate the interrelationships between these factors and cyber deviation. Participants were 485 middle and high school students in the Jeonbuk region. The results showed that tension and self-control were predictors of cyber deviation and that internet addiction was a mediating variable for both the predictors. Anonymity was found to have a mediating role, but only in respect of the tension-cyber deviation pathway. These findings suggested a number of implications. Firstly, the educational programs on cyber deviation should be different from the existing deviation prevention programs. Secondly, measures to prevent internet addiction are needed for the effective prevention of cyber deviation. Lastly, the finding of a relationship between anonymity and cyber deviation indicates the need to adopt a long-term perspective drawing on values education techniques to develop a code of cyber space ethics for "netizens".

Excellent employees are those who take on extra responsibilities and commitments at work. Hence, employees must pay attention to out-of-role activities that can help the company perform better. When a person takes on more responsibilities than he can handle, they will have to deal with the issue of work-family balance. This paper examines how the consistency of WFC affects employees' organizational citizenship behavior (OCB) using the Resource Conservation Theory. This study uses empirical research methodologies to assess 417 employees as a sample. (1) When the matches of work-to-family conflict (WFC) and family-to-work conflict (FWC) are consistent, the employee self-control resource depletion level is lower, and OCB is higher in the "high-high" consistency matching state. (2) The "low-high" match had a higher OCB than the "high-low" match when the WFC and FWC matches were inconsistent. (3) In the process of WFC affecting OCB, the depletion of self-control resources acts as a mediating factor. (4) Emotional intelligence plays a moderating role in the whole model. The lower the emotional intelligence was, the stronger the positive relationship between the consistency of WFC, FWC, and self-control resource depletion was.

This study tests the effects of differential association, definitions, differential reinforcement and imitation from social learning theory in the explanation of university students' crimes in social network services. In addition, this study tests the interaction effects between social learning factors and other factors such as low self-control, subcultural environment, and crime opportunity for the integrated approach. Using data from 486 university students in Seoul, results show that both definition and imitation have significant influences on crimes, even though differential association and differential reinforcement factors have no significant influences on crimes in social network services. Results also reveal that there are significant interaction effects between definition and subcultural environment, which meana that definition has a strong effect on crimes in high subcultural environment. In addition, it is found that reinforcement has also a strong effect on crimes in high crime opportunity and that interaction effect between imitation and low self-control is significant, which means that imitation has a strong effect on crimes in low self-control students.

Work-related low back pain is one of the major factors that cause the loss of working power especially in actively working age, therefore controlling the work-related low back pain is one of the major issues in the field of industrial safety and health. This study was performed for detecting the risk factors and proposing the efficient control program of the work-related low back pain. The subjects were male workers employed at the manufacturing industry in Pusan with longer than 6 months' working duration. The data was collected by self-reported questionnaire and interview from May 1 to October 31,1992. The contents of questionnaire were as follows:. the experience of low back pain within the recent one month, general characteristics(age, marital status, education level, religion, regular exercise), physical characteristics(height, weight), employment status(working duration, daily working hours, rest during work, satis(action fur the job), type of work and working environments(posture, forward bending, lifting and movement, satisfaction for table and chair). The result was analyzed for 608 entire respondents by case-control comparative method. The number of cases was 152 with a history of work-related low back pain, so the relative frequency of self-reported work-related low back pain was 25.0%, and the number of controls was 344 without any history of low back pain. As a result, two characteristics of the employment status(working duration, satisfaction fur the job) and all characteristics of type of work and working environments showed a statistical significance between the case and control groups(p<0.01). The Oddb ratios of these variables for Work-related low back pain were calculated. They were 7.88 for the satisfaction fur chair, 7.86 for lifting and movement,3.31 for satisfaction for table, and 2.22 fur bending forward(p<0.01). And for the multivariate logistic regression analysis confirmed that unsatisfaction for table was independent risk factor for Work-related low back pain. In summary, though this study was based upon the self-reported questionnaire and the subjective complaints, the satisfaction for chair, lifting and movement, satisfaction for table, and bending forward concerned with the type of work and working environments were considered as the main factors causing the work-related low back pain, and the work-related low back pain may be preventable by the ergonomic control of these factors.

This study conducted the following experiment to examine change of physicopsychological function on Dynamic Trunk Control Exercise(3D-DTCE) and Static Trunk Control Exercise (STCE) to chronic low back pain patients subject for lumbago therapy and management. Physical function was measured by equlibrium and lumbar muscle activities and psychological function was measured by self-efficacy on comparative analysis of pre, post exercise and each groups in 30 lumbago patient subject. Equlibrium was measured by total, front back and left right sway index, lumbar muscle activities were measured by abdominal rectus and oblique abdominalis, erector spinae and self efficacy with lumbago patients was measured index of self efficacy. These result lead us to the conclusion that each group were statistically improved at all physicopsychological test. but equlibrium and lumbar muscle activities were more statistically improved at DTCE group and self efficacy with lumbago patients were not differanced on each group. Consequently, DTCE would be lead to positive increment of physical function more than STCE.

Purpose: This study focuses on investigating the effectiveness of simulation education on emergency management using a low-fidelity simulator as related to clinical skill performance, self-confidence, knowledge, learning satisfaction, and critical thinking disposition in new nurses. Methods: A pre-post test experimental design of nonequivalent control group was applied. Fifty-five new nurses were recruited, 28 nurses for the experimental group and 27 nurses for the control group. A simulation education for emergency management comprising knowledge lecture, team learning, skill education, team simulation, and debriefing was developed and implemented from Feb. 14 to 27, 2015. Data were analyzed with percentage, average, and standard deviation, chi-square, and t-test using SPSS. Results: The experimental group showed significantly higher knowledge (t=5.81, p<.001), clinical skill performance (t=10.08, p<.001), self-confidence (t=-6.24, p<.001), critical thinking disposition (t=2.42, p=.019), and learning satisfaction (t=4.21, p<.001) for emergency management compared with the control group who had traditional lecture education. Conclusion: The results indicate that a simulation education using a low-fidelity simulator is an efficient teaching method for new nurses to deepen their clinical skill performance, self-confidence, knowledge, learning satisfaction, and critical thinking disposition in learning emergency management.

Purpose: The goal of this study was to find out factors influencing the health promotion behavior of low-income vulnerable 4th, 5th and 6th-grade elementary school students. The specific goals were: first, to find out difference in health knowledge, self-esteem and health promotion behavior according to general characteristics; second, to investigate the correlations among health knowledge, self-esteem and health promotion: and, third, to analyze factors influencing health promotion behavior. Methods: The subjects of this study were 137 low-income vulnerable 4th, 5th and 6th-grade elementary school children who were participating after-school programs in Seoul. Results: Statistically significant differences were observed in health knowledge, self-esteem and health promotion behavior between girls and boys. In the sub categories, differences were observed in personal hygiene and health responsibility, stress management and personal relationship. The correlation of health promotion behavior with self-esteem and health knowledge was statistically significant. Regression analysis revealed that the influencing factor is self-esteem with the other variables under control. Conclusion: Health promotion education requires low-income vulnerable elementary children to increase their self-esteem. We recommend that it should be one of the most effective ways to split boys and girls to educate them in disparate classrooms.

Distributed resources such as renewable energy sources and ESS are connected to the low voltage direct current(LVDC) distribution network through the power conversion system(PCS). Control power is required for the operation of the PCS. In general, controller power is supplied from AC power or DC power through switch mode power supply(SMPS). However, the conventional SMPS has a low input voltage, so development and research on high input voltage self-power suitable for LVDC is insufficient. In this paper, to develop Self-Power that can be used for LVDC, the characteristics of the conventional topology are analyzed, and a series-input single-output flyback converter using a flux-sharing transformer for high voltage is designed. The high input voltage Self-Power was designed in the DCM(discontinuous current mode) to reduce the switching loss and solve the problem of current dissipation. In addition, since it operates even at low input voltage, it can be applied to many applications as well as LVDC. The validity of the proposed high input voltage self-power is verified through experiments.
