Under quarantine policies related to the Coronavirus, museums have closed or started limited operations. Currently, museums are trying to adapt to the untact situation, while maintaining the museum's original function and communicating with visitors through online platforms. This paper first analyzes the operation status of domestic and foreign museums under untact situations and the operation status of online platforms. In order to reconsider the publicity of the museum, the definition of the museum by ICOM and Hannah Arendt's concept of publicity should be examined. Through this, the importance of the function of public art museums in forming democratic discourse and awakening community could be developed. To this end, first, public forum to discuss the quarantine policy of museums should be developed. Second, local and central governments should support museums financially. Finally, the online platforms of the museum should be more activated. Despite the untact situation of the museum, the publicity of art museums must be addressed in order to discuss the community's difficulties democratically.

The purpose of this study is to survey fundamental limitations and problems of sports event hosting from the critical point of view and to set future-oriented perspective. The reason and legitimacy for hosting sports event have come from pragmatism based on ideological logic behind politics. Thus, the flow of advanced studies was mostly limited to the category of efficiency. However, there is fundamental limitation in sports even hosting in terms of its financial expectation and efficiency. Critical approach will contribute to minimizing side effects caused from blind acceptance through awakening dispassionate and realistic judgment. In addition, rational selection of sports even hosting can be achieved through interconnection of sports culturism's directivity as an advanced sense of sports culture, integrated perspective that penetrates problems of growth and distribution and local governance as apolitical philosophy, and of course, through concentration of energy.

This study investigates the color stimuli of two varieties of foliage plants by extracting electroencephalogram, electrocardiogram and physiology activity data from 30 participants in their 50s or older. Changes in the physiological activity of subjects against six color stimuli were examined. The stimulus to real green plants 'Silver Queen' was set as the control group, and was compared with other groups including the stimulus to real 'Angel' plants and four stimuli to artificial colors (two color images and color schemes of the same green and red plants). Compared to the five groups, the relative theta power spectrum (RT) and the ratio of alpha to high beta (RAHB) increased in the subjects exposed to real green plants. This result demonstrates that the green plant ('Silver Queen') increases the stability, relaxation, and internal concentration of subjects in a proper state of awakening. The result of this experiment showed a statistically significant difference in the level of RT when subjects were exposed to the groups of real green and red plants. This finding indicates that the green plant increases internal concentration more than the red plant. RT and the relative low beta power spectrum (RLB) in the groups of natural colors were higher than the groups of artificial colors when subjects focused their mind on the two types of real plants. However, the level of relative mid beta power spectrum (RMB), ratio of SMR to theta (RST), ratio of mid beta to theta (RMT), relative high beta power spectrum (RHB), and spectral edge frequency 95% were higher when subjects were exposed to the photos and colors scheme of plants than when they were exposed to real plants. The subjects experienced more "comfortable" emotions when they were looking at plants with green colors. Overall, it is recommended to use the natural colors of real plants in places where which stability and relaxation are required. On the contrary, the artificial colors of plants such as their photos and color schemes are useful in places where a high level of concentration is required in a short period of time.

Lighting has been used for a long time as a medium to convey brightness from darkness, and through incandescent lamps and fluorescent lamps, LED light sources have now become the standard in the lighting industry. Recently, the lighting equipment industry has been undergoing rapid digital transformation, starting with smart lighting, and is evolving into smart lighting customized for individuals and spaces through the development of IoT technology, cloud-based services, and data analysis. However, the blue light emitted from digital devices (computers, smartphones, tablets, etc.) or LED lights stimulates the melanopsin in the optic ganglion cells in the retina of the eye, which in turn stimulates the secretion of melatonin through the pineal gland, which regulates the secretion of melatonin. This can reduce sleep quality or disrupt biological rhythms. This interaction between blue light and melatonin has such a significant impact on human sleep patterns and overall health that it is essential to reduce exposure to blue light, especially in the evening. Human-centered lighting refers to lighting that takes into account the effects of light on the physical and mental areas, such as human activity and awakening, improvement of sleep quality, and health management. Many research institutes study the effects in the visible area and the non-visible area. By studying the impact, it is expected to improve the quality of human life. In this study, we plan to study ways to implement human-centered lighting by collecting sunrise and sunset data and linking commercialized LED packages and control devices with open-source hardware.

Xerostomia is defined as a subjective complaint of dry mouth that may be perceived when there is insufficient mucosal wetting. However, the diagnosis and treatment of xerostomia is not that simple because of the fact that the subjective awareness of dry mouth is not always correlated with a diminution in the flow of saliva and there is always a difference between individuals in salivary flow rates needed for normal oral function. In the present study, the aim was to develop a questionnaire to evaluate the dry mouth symptoms and to analyze its reliability and usability as a diagnostic and analytic tool for xerostomia. The questionnaire which consists of 6 Visual Analogue Scale(VAS) type questions to evaluate the subjective oral dryness and 4 questions to evaluate behavior to avoid oral dryness was developed and administered twice with 1 week's interval to the healthy 88 young adults without dry mouth symptoms(44 males and 44 females; mean age was $25.6{\pm}3.1$ years in male and $24.3{\pm}2.1$ years in female). The results were as follows. 1 The intraclass correlation coefficients of 6 questions to evaluate the subjective oral dryness were as significantly high as 0.767 for the degree of oral dryness at other times of the day, 0.850 for the amount of saliva in the mouth, and 0.791 for the degree of effect on daily life due to oral dryness and as high as 0.563 for the degree of oral dryness at night or on awakening, 0.674 for the degree of oral dryness during eating, and 0.641 for the degree of difficulty in swallowing foods. 2. Cronbach's alpha value of 6 questions was 0.982. It can be concluded that the series of questions to evaluate the subjective oral dryness has high internal consistency. 3. Cohen's kappa values of 4 questions to evaluate behavior to relieve oral dryness were as significantly high as 0.850 for the frequency of keeping a glass of water at the bedside and as high as 0.506 the frequency of awakening during sleeping due to oral dryness, 0.419 for the frequency of sipping liquids to aid in eating dry foods, and 0.407 for the frequency of using a candy or chewing gum due to oral dryness. From the results, it can be concluded that the questionnaire consisting of 6 VAS type questions to evaluate the subjective oral dryness and 4 questions to evaluate behavior to relieve oral dryness has reliability of good to excellent level, and that the series of 6 VAS type questions has significantly high internal consistency to evaluate the subjective oral dryness.

Purpose and Method : We have many difficulty of using the existing medical Hurbs based on the theory of Yin-yang and the five elements, this is why we still do not explain the Sasang Constitutional medical Hurb Classification and do not have the Sasang Constitutional Pharmacology exactly, so we easily enter into a dispute and confusion. So through literary consideration about clematis mandshurica Maxim. I try to objectify Sasang Constitutional Clasification of Clematis mandshurica Maxim and the spirit of using Clematis mandshurica Maxim and common property of Sasang Constitutional Medical Hurb and try to find out a clue that search the effect of other Sasang Constitutional Medical Hurb. Result : Qi(氣) and mi(味) of Clematis mandshurica Maxim has bitter and hot taste and have won Qi(溫氣), the color is dark, the using portion of clematis mandshurica Maxim is root as medial Hurb. So Clematis mandshurica Maxim fall down from lung and divied impurity and purity and able to remove the symptom that dryness and fever is solidified like Magnoliae cortex(厚朴). Clematis mandshurica Maxim have the effect of awakening Jin-Qi(眞氣) of lung and divide impurity and purity of Qi(氣) and ack(液) and improve the fuction and structure of Taeumin(太陰人) I think that the method of literay consideration on objectification of Sasang Constitution Pharmacology is of great value.

Numerous Researches on the Buddhist perspective of Wonhyo agree that the Mind is the core principle of Wonhyo's Buddihist perspective. Based on prior research, this paper identifies the philosophy of Mind-only(vijñaptimātratā) in the broader perspective, that is, "Mind is the first principle of the existence", as the core thought of Wonhyo. The objective of this paper is to reorganize the systematic theories of consciousness, one of the principle sectors of Wonhyo's philosophy of vijñaptimātratā. One can find most systematic texts of consciousness of Wonhyo in 『GiSilRonSo』 and 『GiSilRonByeolGi』. Although 『GeumGang SamMaeGyeongRon』 includes some interpretations of consciousness, it is difficult to formulate a consistent structure based on it. Beside tā.JangEui』, which discusses the meaning of vijñaptimātratā centering around affliction, Wonhyo's opinion about important issues of vijñaptimātratā philosophy such as ālayavijñāna, permeation, bījadharma, and aspects of perception appears in fragments. Thus, this paper focuses on 『GiSilRonSo』 and 『GiSilRon ByeolGi』, Wonhyo's interpretation of 『Awakening of Mahāyāna Faith』(大乘起信論), as well as 『IJangEui』, 『PanBiRyangRon』 and 『Geum GangSamMaeGyeongRon』. The researcher examines how one-mind, tathāgatagarbha, and ālayavijñāna become the principles of 'neither arising nor ceasing'(不生滅) and 'arising and ceasing'(生滅) of all beings. The process of how one-mind develops mind in terms of the Absolute(心眞如門) and mind in terms of Phenomena(心生滅門) and its ontological structure are also investigated. In addition, the philosophical significance of Wonhyo's interpretation of tathāgatagarbha and ālayavijñāna analyzed. Besides, the method how various theories about vijñāna from Tathāgatagarbha's and Yogācāra's philosophy can be synthesized is examined based on Wonhyo's arguments. The four aspects of existence(caturākāra 四相) -arising(生), abiding(住), changing(異), and ceasing(滅)- which is transformed according to stages and dimensions of 'arising and ceasing', and phases of mind such as delusion of three fine states(三細) and six rough states(六麤), five consciousness(五意), and six defiled states(六染) are interpreted based on Tathāgatagarbha's and Yogācāra's philosophical system.

Objectives : Upper airway resistance syndrome(UARS) is a sleep-related breathing disorder characterized by abnormal negative intrathoracic pressure during sleep. Abnormally increased negative intrathoracic pressure results in microarousal and sleep fragmentation which underlay UARS-associated complaints of daytime fatigue and sleepiness. Although daytime dysfunction in patients with UARS is comparable to that of sleep apnea syndrome, UARS has been relatively unnoticed in clinical setting. That is why UARS is apt to be excluded in diagnosing of sleep-related breathing disorders since its respiratory disturbance index and arterial oxygen saturation are within normal limits. The current study presents a summary of clinical and polysomnographic characteristics found in patients with UARS. The present study aims (1) to explore characteristics of patients diagnosed with UARS, (2) to characterize the polysomnographic findings of UARS patients, and (3) to enhance the understanding of UARS through those clinical and laboratory characteristics. Methods : This was a retrospective study of 20 UARS patients (male 15, female 5) and 30 obstructive sleep apnea (OSA) patients (male 21, female 9) at the Stanford Sleep Disorders Clinic. We diagnosed patients as having UARS when they met critenia, RDI < 5 characteristic findings of an elevated esophageal pressure($<-10\;cmH_2O$), frequent arousals secondary to an elevated esophageal pressure, and symptoms of daytime fatigue and sleepiness. We used polysomnographic value, which is standardized by Williams et al(1974), as normal control. Statiotical test were done with student t-tests. Results : (1) Mean age of UARS was $41.0\;{\pm}\;14.8$ years and OSA was $50.9\;{\pm}\;12.0$ years. UARS subject was significantly younger than OSA subject (p<0.05). (2) The total score of Epworth Sleepiness Scale (ESS) was UARS $9.7\;{\pm}\;6.3$ and OSAS $11.2\;{\pm}\;6.3$. There was no significant difference between two groups. (3) The mean body mass index was UARS $28.1\;{\pm}\;5.7\;kg/m^2$ and OSAS $32.9\;{\pm}\;7.0\;kg/m^2$. UARS had significantly lower meen body man index than OSAS subjects (p<0.05). (4) The polysomnographic parameters of UARS were not significantly different from those of OSA except RDI(p<0.001), $SaO_2$ (p<0.001) and slow wave sleep latency (p<0.05). (5) Compared with normal control, Total sleep time in UARS subjects was significantly shorter (p<0.001), sleep efficiency index was significantly lower (p<0.001), total awakening percentage was significantly higher (p<0.001), and sleep stage 1 (p<0.001) were significantly higher. (6) OSA patients showed poor sleep quality and distinct abnormal sleep architectures compared with normal control. Conclusions : Conclusions from the above results are as follows : (1) UARS patients were younger and had lower body mass index when umpared with OSA patients. (2) The quality of sleep and sleep architectures of the UARS and OSA patients are significantly different from those of normal control. (3) ESS scores and awakening frequencies of UARS are similar with those of OSA, suggesting that daytime dysfunction of UARS patients may be comparable to those of OSA patients. (4) The RDI and the $SaO_2$ which are important indicators in diagnosing sleep-related breathing disorders, of UARS subjects are close to normal value. (5) According to the the above results, we unclude that despite the absence of $SaO_2$ drops and the absence of an elevated number of apnea and hypopnea, subjects developed clinical complaints which were associated with laborious breathing, elevated Pes nadir, and frequently snoring. (6) Accordingly, we suggest including LIARS in the differential diagnosis list when sleep related breathing disorder is suspected clinically and overnight polysomnographic findings except snoring and frequent microarousal are within normal limits.

Objectives: The aims of this study were to investigate the availability of diagnosis of Yin-deficiency in the elderly with xerostomia and factors influencing subjective oral dryness. Methods: We surveyed 50 patients recruited by the clinical trial, 'Efficacy of Yukmijihwang-tang on Xerostomia in the Elderly: A Randomized, Double-blind, Placebo-controlled, Two-center Trial'. The subjects were assessed on their subjective oral dryness using the Dry Mouth Symptom Questionnaire (DMSQ). Their salivary functions were measured by Unstimulated Salivary Flow Rate (USFR) measurements. In addition, the subjects were evaluated on their Qi-stagnation and Yin-deficiency conditions using the Qi-stagnation questionnaire and Yin-deficiency questionnaire. Results: There were statistically significant correlations between three variables (USFR, DMSQ score and Qi-stagnation score) and Yin-deficiency score. In the multiple regression analysis, the regression model was statistically significant (F = 10.273, p < .001). The factor most strongly influencing the subjective oral dryness was USFR (${\beta}$ = -0.386). Yin-deficiency had the next strongest impact on the subjective oral dryness (${\beta}$ = 0.371). Qi-stagnation affected the subjective oral dryness weakly (${\beta}$ = 0.075). In the simple regression analysis, Yin-deficiency had a statistically significant effect on each of six subscales of DMSQ (p < .01). Among the six subscales, DMSQ-1 ('Oral dryness at night or on awakening') was the most strongly influenced by Yin-deficiency. Conclusions: The results of this study show that the diagnosis of Yin-deficiency in the elderly with xerostomia was available and Yin-deficiency was an important factor influencing the subjective oral dryness. Therefore, the consideration of Yin-deficiency is significant for diagnosis and treatment in the elderly with xerostomia.

Objectives: Parkinson's disease (PD) patients may experience fluent mobility upon awakening from a night's sleep, which is called sleep benefit (SB). Although SB is a phenomenon closely associated with sleep, sleep features of PD are not well characterized. The objectives of this study were, first, to investigate if there are any clinical characteristic features between patients with SB and without SB (NSB), and second, to examine if SB patients are associated with any specific sleep variables compared with NSB patients. Methods: Thirty-three PD patients (14 men and 19 women) participated in this study. All subjects were interviewed to examine whether or not they had SB and overnight polysomnography was performed at the sleep center. Various clinical variables were collected through medical record review. Results: The 331 PD patients were divided into 16 SB group (48.5%) and 17 NSB group (51.5%). SB patients were younger (p<0.02), had higher sleep efficiency (p<0.05), and showed shortened sleep latency (p<0.02) as compared with NSB patients. However, no difference was found between SB and NSB with respect to gender, duration or stage of PD, antiparkinsonian medications prescribed, and predominant motor symptoms. SB did not clearly relate to a specific sleep stage and other sleep variables except sleep efficiency and sleep latency. Although primary snoring was more prevalent in SB patients (p<0.05), other sleep disorders were seen with equal frequency in SB and NSB groups. Conclusion: Our results suggest that good sleep efficiency, shortened sleep latency, and age may have an effect on morning motor function (i.e., SB) in Parkinson's disease.
