Game business has been successfully developed in the world including Korea. Among the many functions, interactivity is the key issue in the state-of-the art gaming system and the success of Nintendo Wii is the example. However, in spite of this success, it is hard to find out the research of the gaming interactivity, for instance what kinds of outcomes are followed by the interactivity. Therefore, the aim of this research tries to disclose the influence of perceived gaming interactivity on various psychological states such as mood, vicarious experience, and vicarious pleasure. The results show that all those factors are influenced by interactivity.

Mammalian physiology and behavior are regulated by an internal time-keeping system, referred to as circadian rhythm. The circadian timing system has a hierarchical organization composed of the master clock in the suprachiasmatic nucleus (SCN) and local clocks in extra-SCN brain regions and peripheral organs. The circadian clock molecular mechanism involves a network of transcription-translation feedback loops. In addition to the clinical association between circadian rhythm disruption and mood disorders, recent studies have suggested a molecular link between mood regulation and circadian rhythm. Specifically, genetic deletion of the circadian nuclear receptor Rev-$erb{\alpha}$ induces mania-like behavior caused by increased midbrain dopaminergic (DAergic) tone at dusk. The association between circadian rhythm and emotion-related behaviors can be applied to pathological conditions, including neurodegenerative diseases. In Parkinson's disease (PD), DAergic neurons in the substantia nigra pars compacta progressively degenerate leading to motor dysfunction. Patients with PD also exhibit non-motor symptoms, including sleep disorder and neuropsychiatric disorders. Thus, it is important to understand the mechanisms that link the molecular circadian clock and brain machinery in the regulation of emotional behaviors and related midbrain DAergic neuronal circuits in healthy and pathological states. This review summarizes the current literature regarding the association between circadian rhythm and mood regulation from a chronobiological perspective, and may provide insight into therapeutic approaches to target psychiatric symptoms in neurodegenerative diseases involving circadian rhythm dysfunction.

Final year students are normally encountering high pressing in their study. In view of this fact, this research focuses on determining mental states condition of college student in final year based on the psycho-physiological information. The experiments were conducted in two times, i.e., prior- and post- graduation seminar examination. The early results indicated that the student profile of mood states (POMS) in prior final graduation seminar showed higher scores than students in post final graduation seminar. Thus, in this research, relation between biosignal representing by heart rate variability (HRV) and questionnaire responses were evaluated by hidden Markov model (HMM) and neural networks (NN).

The Profile of Mood States (POMS) is the most widely used self-report instrument for the measurement of affect or mood in clinical and nonclinical populations. This paper reports on the translation and testing of a Korean version of the POMS. The translation involved three steps: translation, checking agreement, and panel discussions to arrive at consensus. Then, the Korean version of the POMS was tested with a sample of 47 healthy Koreans who lived in the U.S.; they completed the instrument in the morning, at the beginning of work and in the evening, at the end of work. Internal consistencies for the total scale and subscales were high (alphas ＝ .93 and .94). Face and content validity and the cultural relevance of the Korean version of the POMS were tested through review by five bilingual Korean nursing scholars who were familiar with Korean culture and with the current literature on affect, feeling or mood in both English and Korean. The Korean version of the POMS was then compared with the Haeok Fatigue Behavior Check-list and demonstrated with concurrent validity (r ＝ .87, p ＜ .001). Construct validity was established by demonstrating significant differences between the scores on the Fatigue and Vigor subscales (p ＜ .001) at the beginning work and at the end of work.

This study investigates sound, scenery, and soundscape preferences, which are sensory factors that users feel in a healing forest, comparing the difference in recovery by the soundscape. In the barrier-free, wooden walking path of the National Daegwallyeong Healing Forest, a survey site with five different conditions was selected. Users prefer water sounds the most and places with open views for scenery. For the complex sensation of soundscapes, the most preferred is a space where water sounds can be heard, and either a waterfall or an open view can be seen. A profile of mood states test was use to compare users' psychological recovery by the soundscape. It was found that users felt the most positive mood with water sounds and open views. In addition, users' preference for artificial sounds, scenery, and soundscape was the lowest. In the mood state test, it was found that the artificial soundscape incited the most negative emotions.

This study aimed to analyze and compare results from psychological relaxations by using profile of mood state (POMS) and Malondialdehyde (MDA) level as a scale of oxidative damage before and after walking in the forest and on the street. 29 participations (15 men and 14 women) walked in the forest and on the street for 30 minutes of each for two days. The participations filled a questionnaire for POMS and conducted an heart rate variability test, oxidative damage test (MDA as biological marker through a urine test) before and after walking. To compare the psychological states after walking in the two difference places, walking in the forest showed statistically more meaningful results in the section of tension, depression, anger, fatigue, confuse and total mood disturbance (p<0.01) than walking on the street. According to the MDA results, a concentration of MDA showed significant increase after walking on the street (p=0.014). On the contrary to this, a concentration of MDA tended to decrease after walking in the forest (p=0.076). The study showed that the psychological states were more stable and oxidative damages were more decreasing after walking in the forest than walking on the street. In the conclusion, MDA would be biological indicator for assessing the effect of alleviation on the oxidative stress after walking in the forest.

The purpose of this study was to test the effectiveness of self-management relaxation training through biofeedback and progressive muscle relaxation methods. The effectiveness of the experimental methods was tested by measuring the degree of symptoms of stress (SOS), the McNair's profile of Mood States (POMS), the levels of ephinephrine, norepinephrine, pulse rate, blood pressure and natural killer cells. The subjects of this study were sixty six nursing students divided into four groups : two groups were the biofeedback and progressive muscle relaxation groups, the other two groups served as control groups. One was a group of sophomores with no experience at all, the other a junior group without self -management or relaxation training. This study was conducted for eight weeks of clinical practice from April, 26th 1998 to June, 20th 1998. Biofeedback training was done with software developed by J&J company (1-410 form for abdominal respiration training). Progressive muscle relaxation training was done with u audiotape recorded according to Jacobson's Theory. The data were analyzed with frequencies, means, and analysis of covariance using the SPSS program and the significance level of statistics was 5%. The results of the study are : 1) The importance of clinical practice stress reduction is shown in that the level of symptoms of stress in the experimental groups in clinical practice was higher than in the group receiving only a lecture. 2) The relaxation training methods of biofeedback and progressive muscle relaxation were effective in reducing the symptoms of stress under the clinical practice stress conditions. 3) The effectiveness of the biofeedback training relaxation method to reduce symptoms of stress was higher than that of progressive muscle relaxation. 4) The relaxation training methods of biofeedback and progressive muscle relaxation were effective in reducing stressful mood states. 5) The relaxation training methods of biofeedback and progressive muscle relaxation were not effective in reducing epinephrine and norepinephrine levels. 6) The relaxation training methods of biofeedback and progressive muscle relaxation were effective in increaing the number of natural killer cells. 7) The relaxation training methods of biofeedback and progressive muscle relaxation were effective in decreasing high systolic and diastolic values of blood pressure and high pulse rates. In summary, the relaxation methods of biofeedback and progressive muscle relaxation in reducing clinical practice stress were effective in lowering the level of symptoms of stress and the profile of stressful mood states. They were also effective in lowering high blood pressure and pulse rates. The relaxation methods were effective in increasing the number of natural killer cells as part of the immune function. However, relaxation methods were not effective in reducing the catecholamine level. The biofeedback training method for reduction of symptoms of stress was more effective than the progressive muscle relaxation method.

Objectives: This study aims to analyze the association between the severity of sleep apnea, sleep and mood related scales, and activity during sleep in obstructive sleep apnea syndrome (OSAS) patients. Methods: 176 drug-free male patients confirmed as OSAS (average age=$43{\pm}11$ years) were selected through nocturnal polysomnography (NPSG). OSAS was diagnosed with apnea-hypopnea index (AHI) >5, mean AHI was $39.6{\pm}26.0$. Sleep related scales were Stanford Sleepiness Scale (SSS), Epworth Sleepiness Scale (ESS), Pittsburg Sleep Quality Index (PSQI) and Morningness-Eveningness Scale (MES). Mood related scales were Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), State-Trait Anxiety Inventory (STAI) I, II and Profile of Mood States (POMS). NPSG was performed overnight with both wrist actigraphy (WATG). Parameters produced from WATG were total activity score, mean activity score and fragmentation index. We analyzed the correlation between each scale, AHI scored from NPSG and activity score analyzed from WATG. Results: ESS showed significant positive correlation with PSQI, BDI, BAI and STAI I, II, respectively (p<0.01). SSS showed significant positive correlation with PSQI and BAI (p<0.05, p<0.01). BAI showed significant positive correlation with total activity score, mean activity score and fragmentation index (p<0.05, p<0.01, p<0.05).Total activity score showed significant positive correlation with ESS and BAI, respectively (p<0.05). Fragmentation index showed significant positive correlation with ESS, PSQI and BAI (p<0.05, p<0.01, p<0.05). AHI, indicator of sleep apnea is showed no significant correlation with each sleep and mood related scale. Conclusion: The degree of daytime sleepiness tends to be associated with night sleep satisfaction, depression and anxiety, and the activity during sleep rather than the severity of sleep apnea.

Objectives There was a correlation between respiratory index and Profile of Mood States (POMS). However, no study has examined the relationship between hyperventilation and POMS. Therefore, this study showed differences in POMS subscales and respiratory patterns between hyperventilation group and normal group. Methods 20 healthy men and women were to complete Nijmegen and Korean-Profile of Mood States(K-POMS) questionnaire aimed at subjects (13 men, 12 women). By attaching a capnometer to the nasal cavity portion, end-tidal $PCO_2$ was measured. Also, marker was attached at Zhangmen, Juque, Shuifen. The movement of the marker was taken as a web cam. Statistical analysis Mann Whitney U test was used for the nonparametric methods. Results In the subscale of K-POMS were significant differences(Tension-0.001, Anger-0.007, Fatigue-0.002, Depression -0.004) between the normal group and the group with the hyperventilation. In addition, between the two groups were obtained a significant result(0.046) in the movement of the Shuifen acupoint. Conclusions Nijmegen questionnaire score is higher, the higher negative subscale scores of K-POMS. Also, differences in Nijmegen questionnaire score may help to determine the presence or absence of the abdominal breathing.
