The purpose of this research was to investigate the effects of skin pressure by wearing all-in-one on the rhythm of body temperature such as skin and rectal temperature which play a crucial role in the nocturnal rhythm. Five healthy female were participated in the study as subjects. The experimental clothing was an all-in-one, one of the foundation, which is worn for shaping the body. The total experimental periods were 5 days. On the 1st day, subjects did not wear the all-in-one (None), and they wore it for about 12 hours per day from 2nd to 5th day (Wearing1~4). Skin and rectal temperature were measured during the entire experimental days to figure out the rhythm of body temperature during sleep. When subjects wore the all-in-one, the gradients of the forearm and calf skin temperature at the sleep onset were significantly smaller than "None". It indicated that the rise of extremities' skin temperature was low on the "Wearing1~4". The decline of rectal temperature in "Wearing 1~4" was smaller than "None". Therefore, the skin pressure by all-in-one may cause the temperature of extremities' skin and rectum to change, resulting the fluctuation of the circadian rhythm, finally it could have effects on the rhythm of sleep.

All living organisms have a biological clock that orchestrates every biological process and function, and this internal clock operates following a circadian rhythm. This biological clock is known to influence various clinical indicators such as blood pressure and body temperature. Also, the fluctuation of signs and symptoms of diseases including pain disorders are affected by circadian rhythm. It has been reported that the pain intensity of various somatic and neuropathic pain disorders show unique pain patterns that depend on the passage of time. The generation of pain patterns could be explained by extrinsic (e.g., physical activity, tactile stimulation, ambient temperature) and also intrinsic factors (neural and neuroendocrine modulation) that are related to the circadian rhythm. It is important to recognize and identify the individual pain pattern in pain therapy to approve treatment outcome. Moreover, chronotherapeutics which considers pain patterns and pharmacokinetics in context of the circadian rhythm could produce greater analgesia in response to medication. However, only a limited number of studies handle the issue of pain patterns according to circadian rhythm and chronotherapeutics in the orofacial region. The present review intends to reflect on the most recent and relevant data concerning the bidirectional relation between pain disorders of the orofacial region and circadian patterns.

The purpose of this study is to find out the difference in circadian rhythm and level of fatigue between ER and General Ward Nurse. This study was done through analyzing body temperature, heart rate and major electrolytes such as $Na^+$ and $K^+$ concentration on urinalysis, which are related to factors of circadian rhythm and level of fatigue. The subjects, 17 nurses from Emergency Room and 25 nurses from general ward, were selected from a General Hospital in Taegu City on August 8 to 23, 1998. And the data were analyzed by proportion, t-test, chi-square and Pearson's Correlation, ANCOVA, using SAS program. The results of this study were shown as follows: First, The difference of Maximal and minimal heart rate was significant between ER group and general ward group. However, body temperature difference wasn't notable. Second, Urine $Na^+$ concentration on urinalysis was lower and $K^+$ concentration on urinalysis was higher in ER group than general ward group significantly. Third, Fatigue level was higher in ER group than general ward group significantly. Fourth, through urine concentration, significant relations in circadian rhythm of ER nurse group and general ward group and their fatigue level were found. Urine $Na^+$ concentration on urinalysis of ER nurse was significant related with their fatigue level. In conclusion, the effect of fatigue on circadian rhythm is greater in ER group than general ward group during night shift. This study could be a help in improvement of nurse's health and understanding the effect of fatigue on health.

This study aims to grasp the vital rhythm of the Chapel at Ronchamp by analyzing its rhythm through Henri Lefebvre's 'rhythmanalysis' in an effort to show the possibility of approaching the presence of this chapel. For the purpose of this study, Lefebvre's thought of rhythmanalysis was first contemplated, and a case study analysis was conducted on the concept and presence of the chapel in the design process. On this basis, examples of the chapel's rhythms were analyzed through Lefebvre's dialectical analysis of the triad of time(melody), space(harmony) and energy(rhythm). The results of analysis are as follows: First, the concept intended by Le Corbusier in the process of designing the Chapel at Ronchamp is expressed as the acoustic form, the modulor corresponding to the scale of the music, the light and shadow of counterpoint, and the opposite composition of musical changes. Consequently, the concept-mediated presence of this chapel is the presence of music. Second, at the Chapel at Ronchamp, a Lefebvre's rhythmanalyst experiences, or rather senses, two vital rhythms of an antithetical unity (i.e., acoustic curved rhythm and modulor-generated linear rhythm), with reference to his/her own rhythms. These rhythms are a dialectical union of spatiality of melodies temporalized through continuity, (i.e., acoustic curved form and modulor-generated linear form), and temporality of harmonies spatialized through simultaneity (i.e., light and shadow, materials and color, form of interpenetration, and stairs or windows/doors). These rhythms carry the measures generated by music-specific repetitions and differences in movements(energy). Consequently, the rhythm-mediated presence of this chapel is also the presence of music. In conclusion, the Chapel of Ronchamp indicates that an approach toward its presence can be realized through vital rhythms derived from Lefebvre's 'rhythmanalysis'. This study holds significance as an analysis of spatial rhythm and presence, employing a philosophical thought.

Objectives: The researchers investigated the relationship between sleep pattern (circadian rhythm/sleep deprivation), eating habit, and the perceived skin condition of female adults, in orders to provide valuable information to women who want to maintain healthy skin and professionals in health promotion. Methods: The participants were 297 female adults whose ages ranged from 20 to 60 (M=35.14, SD=10.37). The questionnaires and psychological tests used in this research included the following: Circadian Rhythm Questionnaire, Sleep Deprivation Scale, Eating Habit Questionnaire, Skin Condition Questionnaire, Scale for Perceived Skin Health. Results: Results indicated that evening type women had more fatty skin and felt their skins less healthier than morning type. Although women who did not deprived their sleep had more fatty and sensitive skin and felt their skins less healthier than women who deprived their sleep, sleep deprivation was positively related to the morningness, and the morningness was negatively related to the preference of fatty and spicy foods. Only the preference of fatty foods among eating habit was positively related to the fatty and sensitive skin, and negatively to the perceived skin health. Regression analyses with circadian rhythm and the preference of fatty foods revealed that only circadian rhythm was significant predictor for the fatty skin, while the preference of fatty foods was only significant predictor for the sensitive skin and the perceived skin health. And, circadian rhythm and the preference of fatty foods accounted for around 12.0% variance of the fatty skin. Conclusion: This study reiterates the roles of fatty foods on skin health, and found the role of circadian rhythm on skin health, and it is needed to explore the relationship between sleep deprivation and skin condition further. These results may provide useful information for health practitioners.
