This paper was done to verify the use of the Profile of Mood States (POMS) which was developed by McNair, Lorr, and Droppleman(1992) with modifications so that it is appropriate for Korean elders. Through the modified tool, it is possible to examine the mood of Korean elders and to contribute to the welfare of elders. The subjects were 370 elderly persons over 60 years old and the data for 319 persons(86%) were analyzed. The research tool was the POMS translated by Yun(1993) and corrected by the researcher. Data were collected between February 12 and April 9 in 1996 and analyzed using the SAS package. The result are as follows 1. Items with low Cronbach coefficient alpha which means low correlation with total items were removed. The items were removed : friendly, tense, considerate, relaxed, sympathetic, resentful, good-natured, rebellious, trusting, carefree. 2. Overlapped or ambiguous items were discussed by colleagues and elders through verification of con-tent-validity and were removed. Five items were removed in tense-anxiety, seven, in depression-dejection, three, in vigor-activity, three, in fatigue-inertia, two, in confusion-bewilder-ment, five, in friendliness, and six, in anger-hostility. Thirty four items remainined : angry, clear-headed, lively, confused, sorry, shaky, list-less, peeved, sad, active, blue, hopeless, spiteful, uneasy, unable to concentrate, fatigued, helpful, nervous, lonely, cheerful, bitter, exhausted, anxious, ready to fight, sluggish, helpless, alert, deceived, efficient, worthless, forgetful, terrified, vigorous, and uncertain about things. 3. Factor analysis was done in order to confirm construct validity and three factors were obtained from the result. The first factor, 'anxiety-depression' included 21 items, the second factor, 'vigor' included eight items, and the third factor, 'anger' included five items. Cronbach coefficient alpha for the 34 items was. 95. Based on the result, the following is suggested : 1. a contribute to elder's welfare can be made by examining Korean elder's mood in life. 2. there is a need to develop tools appropriate to Korean culture which can be used to examine elders' mood. 3. The modified POMS tool needs to be reverified with appropriate age groups and settings.

Proper orthogonal decomposition (POD) is a method for extracting bases for modal decomposition from the ensemble of dynamic signals. Using the POD method, we analyzed the proper orthogonal modes (POMs) of AFM microcantilevers in dynamic mode operations such as Tapping Mode. The POMs and POVs (proper orthogonal values) were computed through MATLAB simulation for the 5-mode model of the microcantilever. We found that the POV portion of the higher POMs of the tapping microcanilever slightly increased in comparison with no tapping. This implies that the modal energy in the fundamental mode can be transferred to the higher modes during tapping.

Given the growing attention to nature and health in modern society, this study considered the role of a waterscape facility as a key element in a landscape's influence on users' physiological and psychological responses. The subjects were 28 university students, and the collected data included systolic and diastolic blood pressure, salivary amylase concentration, semantic differential (SD) scales, and profile of mood states (POMS). As compared to a space without any waterscape element (Type G), relaxation in a space with a waterscape element (Type W) was found to significantly reduce of systolic and diastolic blood pressure and salivary amylase concentration. The SD scale and POMS findings showed that Type W evoked active, bright, dynamic, free, vital, interesting, and cheerful images and improved mood states by enhancing vigor while inhibiting depressive feelings. These findings indicate waterscape facilities can improves users' mood states and may enhance their health.

Purpose: To determine the clinical and radiological features of peripheral osteoma of the mandible (POM) in a Korean population and to compare with previous reports. Materials and Methods: Sixteen cases of POM found in 15 Korean patients who visited Seoul National University Dental Hospital between 1980 and 1998 were reviewed to determine their clinical and radiological features. Results: The 15 patients. five males and ten females. ranged in age from 22 to 69 years. with a mean age of 40.7 years. Six POMs were located on the buccal side of the mandibular body and five on the lingual aspect of the mandibular body and five on the lower border of the mandible. The duration of the lesion ranged between 1 and 10 years. The size of the lesions. in their great diameter. ranged from 6 to 26 mm. with a mean of 14.1 mm. Six POMs were pedunculated. nine sessile. and one bell-shaped. Eleven POMs were compact types and five were cancellous ones. Conclusion: The clinical and radiological features of these Korean series were broadly consistent with those of non-Korean populations reported previously. The principal difference was that all POMs under 35 year-old age were compact types.

Objectives : The purpose of this study was to investigate the efficacy of inhalation therapy using Zizyphus jujuba var. spinosa blended oil and spa therapy on stress in adults. Methods : The study design was a double blind, randomized, single center clinical trial. A total of 30 volunteers who were highly stressed and were over 9 points on POMS(profile of mood states) participated in this study. Inhalation therapy using Zizyphus jujuba var. spinosa blended oil and spa therapy were applicate for the experimental group and Jojoba oil inhalation and spa therapy was given for the control group. During the 2 weeks, the participants were treated about inhalation and spa therapy twice a week. The treatment sequence is spa therapy after inhalation therapy. Result : The improvement of stress was evaluated by POMS, HRV(Heart Rate Variability), EEG(Electroencephalography), PSQI(Pittsburgh Sleep Quality Index), salivary cortisol. After treatment, POMS was significantly decreased between the experimental group and the control group. In other measurement(HRV, EEG, PSQI, salivary cortisol) except POMS, there were not significant. Overall, however, they showed a tendency to alleviate stress in the experimental group. Conclusions : We suggest that inhalation therapy using Zizyphus jujuba var. spinosa blended oil and spa therapy might be effective on stress.

Proper orthogonal decomposition(POD) is a method for extracting bases for modal decomposition from the ensemble of signals. We verified the connection of the proper orthogonal modes(POMs) and the linear normal modes(LNMs) through MATLAB simulation for the simple cantilever and AFM microcantilever models. Using the POMs, we can analyze and model effectively the dynamic mode of AFM microcantievers.
