Objective: This entire study has two parts. Study I aimed to develop a psychological assessment scale and the study II aimed to investigate the effects of LFN (low frequency noise) on the psychological responses in humans, using the scale developed in the study I. Background: LFN is known to have a negative impact on the functioning of humans. The negative impact of LFN can be categorized into two major areas of functioning of humans, physiological and psychological areas of functioning. The physiological impact can cause abnormalities in threshold, balancing and/or vestibular system, cardiovascular system and, hormone changes. Psychological functioning includes cognition, communication, mental health, and annoyance. Method: 182 college students participated in the study I in development of a psychological assessment scale and 42 paid volunteers participated in the study II to measure psychological responses. The LFN stimuli consisted of 12 different pure tones and 12 different 1 octave-band white noises and each stimulus had 4 different frequencies and 3 different sounds pressure levels. Results: We developed the psychological assessment scale consisting of 17 items with 3 dimensions of psychological responses (i.e., perceived physical, perceived physiological, and emotional responses). The main findings of LFN on the responses were as follows: 1. Perceived psychological responses showed a linear relation with SPL (sound pressure level), that is the higher the SPL is, the higher the negative psychological responses were. 2. Psychological responses showed quadric relations with SPL in general. 3. More negative responses at 31.5Hz LFN than those of 63 and 125Hz were reported, which is deemed to be caused by perceived vibration by 31.5Hz. 'Perceived vibration' at 31.5Hz than those of other frequencies of LFN is deemed to have amplified the negative psychological response. Consequently there found different effects of low frequency noise with different frequencies and intensity (SPL) on multiple psychological responses. Conclusion: Three dimensions of psychological responses drawn in regard to this study differed from others in the frequencies and SLP of LFN. Negative psychological responses are deemed to be differently affected by the frequency, SPL of the LFN and 'feel vibration' induced by the LFN. Application: The psychological scale from our study can be applied in quantitative psychological measurement of LFN at home or industrial environment. In addition, it can also help design systems to block LFN to provide optimal conditions if used the study outcome, .i.e., the relations between physical and psychological responses of LFN.

Purposes: Despite a lot of prior studies on psychological empowerment on positive outcomes, the objectives of this paper were to examine the role of psychological empowerment on informal learning and the mediation role of informal learning between psychological empowerment and outcome variables focused upon physical therapists working in hospital industry. Methodology: Using survey methods, the data were collected from 198 physical therapists who have worked in Ulsan city and attended in annual meeting. Findings: Results showed that psychological empowerment predicted informal learning positively but differences in mediational mechanism. Specifically, the path between psychological empowerment and proactive behavior partially mediated but no mediating effect between psychological empowerment and helping behavior. This study identified the main role of psychological empowerment on informal learning, and it expands on positive functions of the concept to learning area in organizations. The other results help advanced understanding of differential mechanism through informal learning in the process between psychological empowerment and both outcomes. Practical Implications: The current study contributes to expend the area of prior findings on psychological empowerment to learning activities implemented by individual volunteer effort. For hospitals operating the teams of physical therapy, the significance for considering psychological empowerment is highlighted as for individual growth related to job and for change behavior in the individual level.

The purpose of this study is to analyze the differences in color, pattern, and texture of functional materials of outdoor clothing according to new senior women's psychological comfort. The data were collected from 163 female respondents aged 55-64 living in Busan. The results of the study are as follows. First, both the high and low psychological comfort groups preferred soft material the most. The high psychological comfort group particularly preferred soft textures and highly evaluated textured material in general. Second, both groups mostly preferred plain patterns while the high psychological comfort group preferred the dot pattern more. Third, in terms of colors, the high psychological comfort group preferred navy and purple, while the low psychological comfort group preferred brown. As to achromatic colors, both groups preferred black the most with the high psychological comfort group preferred gray and white more than the other group. Fourth, the high psychological comfort group preferred colors and patterns of clothing that made one look the most slimming, while the low psychological comfort group strongly preferred colors and patterns of clothes. Therefore, our results suggest that new senior women have a strong interest in outdoor clothing, not only in terms of textile functions, but also having interest in textile designs. In particular, the new silver women value psychological comfort in colors more than patterns of textile design.

The purpose of this study was to investigate the relationship between parent's conflict, paternal/ maternal grandmother's psychological support and school-aged children's well-being. The subjects were 227 6th grade school-aged children in elementary school who were 128(56.4%) boys and 99(43.6%) girls. Instruments used in this research were CDI(Children's Depression Inventory), CPIC(The children's perception of interparental conflict scale), and psychological support scale. The data were analyzed by simple regression, standard multiple regression and hierarchical multiple regression(using SPSS 12.1). Major findings were as follows: (1) There was no difference in maternal grandmother's psychological support and paternal grandmother's psychological support. (2) Maternal grandmother's psychological support was more important variable affecting school-aged children's well-being than paternal grandmother's psychological support. (3) Paternal/maternal grandmother's psychological support operated as a main effect with school-aged children's well-being increasing as paternal/maternal grandmother's psychological support increased. There were not interaction effects of parent's conflict and paternal/maternal grandmother's psychological support on school-aged children's well-being. That result showed that paternal/maternal grandmother's psychological support did not moderate negative effects of parent's conflict on school-aged children's well-being.

The etiopathogenesis of burning mouth syndrome (BMS) seems to be complex and many patients probably involves interactions among local, systemic, and/or psychological factors in the pathophysiologic mechanism. Although there are controversies over whether the psychological factor is a cause or a result of BMS, several studies have supported strong relationships between psychological factors and chronic pain. It has been suggested that somatic complaints from unfavorable life experiences may influence both individual personality and mood changes; however, initiation of BMS symptoms is not necessarily correlated with stressful life events despite their elevated psychological stress. If the psychological distress is not a causal factor of BMS, it seems that BMS patients may be particularly vulnerable to psychological problems, primarily depression, anxiety, and hostility due to the characteristic entities of BMS such as chronic persistent pain itself. It seems likely that both physiological and psychological factors play a role in causing, perpetuating and/or exacerbating BMS; therefore, both two components of the patient's symptoms must be addressed. The acceptance of psychological factors by the patient is often an important element of BMS, management. The evaluation of psychological and emotional status of BMS patient enables clinicians to recognize prolonged negative and subclinical factors which can complicate the management of pain or indirectly perpetuate other physical factors. This evaluation improves the doctor-patient relationships, motivation, and compliance through a correct understanding of the clinical problem. Appropriate emotional and psychological evaluation may be required prior to developing a treatment plan in order to gain the successful treatment outcome.

The purpose of this study is to investigate (1) the relationship between gender-role attitude and psychological well-being related to the division of household labor and (2) the effect of congruency between gender-role attitude and the division of household labor on psychological well-being for the elderly. In this study, independent variable is gender-role attitude, mediating variable is the division of household labor and dependent variable is psychological well-being. Psychological well-being consists of depression and happiness. The hypotheses of this study are as follows: 1) Gender-role attitude affects psychological well-being of the elderly. The more egalitarian gender-role attitude, the higher degree of psychological well-being, whereas the more traditional gender-role attitude, the lower degree of psychological well-being. 2) The division of household labor influences psychological well-being of the elderly. The higher degree of division of household labor is likely to show the higher degree of psychological well-being. 3) The congruency between gender-role attitude and the division of household labor affects psychological well-being. As the relationship between gender-role attitude and the division of household labor is more congruent. psychological well-being increases. The results of the study are summarized as follows: 1) There is no relation between gender-role attitude and psychological well-being for the elderly. 2) The division of household labor affects psychological well-being for husband. The higher degree of division of household labor, the higher degree of psychological well-being. The result shows that husbands are involved in household labor involuntarily. 3) Congruency between gender-role attitude and the division of household labor affects psychological well-being. As the relationship between gender-role attitude and the division of household labor is more congruent, the degree of depression decreases. 4) Wives participate in most of household labor. Gender segregation in household labor is found in elderly family. 5) Health, income, network of children or sibling, and community network affect psychological well-being. The healthier, higher income and stronger network are likely to show the higher degree of psychological well-being.
