  • People tend to resist changing their software even alternatives are better then the current one. This study examines the resistance to change in the use of software from the switching costs perspective based on status quo bias theory. For this study, we select Web Browsers as software. Based on the classification of switching costs into three groups (psychological, procedural, and loss), this study identifies six types of switching costs (uncertainty, commitment, learning, setup, lost performance, and sunk costs). This study tests the effects of six switching costs on user resistance to change based on the survey of 204 web browser users. The results indicate that lost performance costs and emotional costs have significant effects on user resistance to change. This research contributes towards understanding of switching costs and the effects on user resistance to change. This study also offers suggestions to software vendors for retaining their users and to organizations for managing user resistance in switching and adopting software.

  • New information technologies have often been treated as innovations for target users. Although users in recent times have had significantly more opportunities to be socialized with information technologies, the rapid pace of technology development usually means that every new technology represents a fairly major change over the previous one. Although a fairly significant body of research that empirically tests these alternative models and theories is now in existence, some questions with regard to the role of perceptions in innovation adoption remain unanswered. This paper reports the results of a field study examining adoption of an information technology innovation represented by an internet application. Moreover, the study examines the effects of an important moderating influence-personal innovativeness-on this adoption process. Finally, the study seeks to shed further light on the determinants of perceptions by examining the relative efficacy of mass media and interpersonal channels in facilitating perception development.

  • Chronic functional constipation is a common problem in childhood, with soiling a significant issue. It presents a management problem for pediatrician, and parental concern is high. About 5% of pediatric patients is known to have constipation and/or encopresis which is the second most referred disease in pediatric gastroenterology clinic, accounting for up to 25% of all visits. The etiology of constipation was based on initiation factors including vicious cycle concept, genetic factors, psychological factors, dietary influences and histologic abnormalities of colon. Emphasis is placed on the evaluation and management options that are available to the treating pediatrician. Careful history taking is most important to diagnose functional constipation. In addition, diagnostic tests such as plain abdominal radiograph, colonic transit study, anorectal manometry, barium enema were helpful to diagnose the constipation. Childhood constipation can be very delicate to treat. It often requires prolonged supports by physicians and parents, demystification, medical treatment and especially with the child and parent's cooperation.

  • It is getting higher the demand on a good sound in a car. Like some other sensory qualities, achieving a good sound is still treated as a black-box followed by the individual taste of tuning engineers. This study aims to define the attributes of a good car audio sound and the assessment factors affecting the sound quality. With a variety of surveys on professional listening groups and car audio installers, 26 most frequently used vocabularies are selected as typical presentations of car audio sound quality. After repetitions of listening tests with deliberately selected test CD, pre-recorded 15 different digital car-recordings, headphones replay system, and three different listening groups, it is proved that there are at least 5 different assessment factors which significantly affect the car audio sound quality. They are high fidelity, spectral balance, tonal accuracy, sound stage and acoustic fault.

  • The purpose of the present study is to examine relationships between disconnection and rejection schema, defense mechanism, and mental health in college students using structural equation modeling. The present study suggested a proposed model in which defense mechanism exerted a full mediating effect on the relation between disconnection and rejection schema and mental health. Goodness of fit tests were used to compare the proposed model against competing models. The subjects consisted of 304 college students. They completed the Young Schema Questionnaire(YSQ-SF), the Defense Style Questionnaire(DSQ), and the Mental Health Scale. The results showed that the second model had a better goodness of fit. Based on these findings, it is suggested that psychological interventions for mental health in college students should consider strategies to use more flexible and more adaptive defense mechanism style.

  • The purposes of this research were to develop a family life education program for single-parent families in rural area and to investigate the effectiveness of education through continuous tests.For these objectives, the concurrent-type program for single-parent families that emphasized communication skills, psychological strategies, and the importance of social support system was constructed. The effectiveness of the program was evaluated by pre-, post- and delayed test through 88 single parents and their children and it was analyzed by paired t-test. The results suggested that the program was effective in improving self-esteem, self-confidence and in decreasing depression. This effectiveness was more in single-father families than single-mother families. But especially in children this effectiveness was diminished as times passed. For maintaining this effectiveness in program, more frequent and continuous following education was demanded.

  • Personality can be understood in terms of cognitive and informational modulation. Augmenting and reducing evoked potential (AREP) has been known as the one of method to test this cognitive characteristic. Especially, many studies have been performed on the relationship between AREP and the Zuckerman Sensation Seeking Scale (SSS) and the Eysenck Personality Questinnaire (EPQ), which are well known as the psychological tests of personality. Generally sensation seekers tend to be augmenters and low sensation seekers tend to the rend to be reducers of EP. However, there are some reports that EP reducers are more extraverted on the EPQ and more sensation-seeking on the SSS than EP augmenters. These results may imply regulatory function of brain can be different depending on brain areas. According to the result of author's studies it can be assumed that frontocentral area works consistently with personality trend whereas right posterior temporal area performs inhibitory regulation against personality trend.

  • It is naturally to be expected that occupational stress on seafarers has specific characters compared to workers engaged in other industries. Because the physical rigors of working and living at sea has been endured as a part of job. The purpose of this paper is to figure out physical changes on seafarers resulted from ordinary shipboard life on the ocean-going cargo vessel. To do this, we performed biochemical inspections testing blood and urine for 28 crews, and measured heart rate of officers engaging in some bridge duties. The tests showed that creatinine, uric acid, total cholesterol, HDL-C, LDL-C of some crews fell down to level which could make a bad impact on human body. And the heart rate of deck officers had vibrated with rather wide amplitude whenever they have got some work-related psychological pressure.

  • This study aimed to develop the elderly care program for seniors in rural areas and to evaluate its efficacy through pre- and post-tests. For them, this study carried out a total of 8 sessions that includes 4 aims, such as understanding rural elderly, volunteer activities, psychological help, and aids to daily living, on 36 persons over the age of 60 years in rural areas. The data was analyzed by paired t-test to 36 elderly. The results of the study are as follows. First, looking at changes in knowledge about aging, objective evaluation of knowledge showed significant differences (t=-2.22, p<.05), but evaluation of elderly's perception-change didn't show significant differences between before and after. Second, volunteer attitude didn't show significant differences between before and after, but after the training, 75% of them answered 'yes' to question that asked whether they'd like to participate in elderly's volunteer caring activity for other elderly within the town in the future, which gave us certain expectation that the attitude towards volunteer activities might change positively in the future. Third, objective evaluation of knowledge for psychological help didn't show significant differences between before and after. But elderly's subjective perception showed significant differences (t=-2.82, p<.01). Fourth, evaluating changes in knowledge for elderly's aiding daily life, both the objective evaluation and subjective evaluation didn't show significant differences between before and after. Fifth, satisfaction of the program showed high scores over 4 points: contents, education methods, education place, education time. The most helpful topics for them were counseling (27.8%) and dementia (27.8%), followed by elderly and aging (16.7%), elderly's residential environment (13.9%), elderly's dietary life (9.3%) and volunteer activities (5.6%).

  • The paper describes measurement techniques for an acoustic transfer characteristic of ship's bridge stimulated by a whistle sound The response sounds, according to the opening-shutting conditions of bridge doors for Training Ship ‘SAENURI’, are measured by B&K 2260D equipment, and then the frequency responses are extracted by B&K 7830 software. To evaluate the measured transfer characteristic, the 128th order FIR (Finite Impulse Response) filters, containing the different frequency characteristics, are constructed based on the frequency sampling-based design method Using evaluation indexes with six scales, psychological assessments by five subjects are carried out with test sounds which are obtained from convolving the source signal with FIR filters. As results of tests, the test sounds gives $A_S$ 3.3∼4.7 which means the psychological sense of ‘it is almost similar sound as original ones in a real world’, and thus it is clearly seen that the proposed method can be used for the measurement of an acoustic transfer characteristic of ship’s bridge.
