Napping is a natural and universal phenomenon. There are some differences depending on the age, but they are common throughout life. As research on naps in sleep medicine has recently increased, negative perceptions about naps are gradually decreasing with development of new and positive perspectives. First, naps relieve fatigue and sleepiness and increase arousal, improving cognitive abilities. Even in the process of memory consolidation, which allows retention of learned memory content, a period of short daytime sleep shows the same results as nocturnal sleep. In addition, evidence of the contribution of sleep to emotional regulation is increasing. The role of the nap has been extended recently to areas associated with immunity and pain. However, naps can disturb sleep at night. There are also concerns that habitual naps in old age are linked to cardiovascular risk and increased mortality. Various aspects and values of naps are being gradually unveiled. However, compared to that of night sleep, research on naps is insufficient, and more research on naps is required.

A state wedding ceremony of kings and crown princes in the Chosun Dynasty was systemically formalized in a book Five National Ceremonies (1474) as one of the five major formal events of the royal auspicious ceremonies(Ga-rae). For a state wedding, Ga-rae Protocol was made by a devision for Ga-rae temporarily established for the occasion. A total number of auspicious ceremony protocols of kings and crown princes amounts to 20 in the span of 279 years. Among the proposals, the wedding of Soon-jong in the Imo Year of 1882 is described most thoroughly. Nap-bin-ui(reception of bride) comprises six rituals which are nap-chae, nap-jing, go-gyi, chaek-bin, chin-young, and dong-ryae. A grand formal costume of the crown prince is granted based on the 'Seven Parts Formal Costume' of the first year of the king Moon-jong in 1450 together with an official costume for crown prince(Gon-myeon-chil-jang) arranged in the third year of the king Young-rak. In the royal palace of the Chosun Dynasty, the granted formal costume of the crown prince is officially recorded as a code and presented in a Gwon-ji-il section of the Formalities of the Five National Ceremonies. The formal costume and its accessory set for the crown prince recorded as a code are described in Sangbang Jeong-ryae as the formal costume of the crown prince section published by the king's request at the high senate commission in the 28th year of the king Young-jo in 1752. The aim of the study is to investigate the formal costume of the crown prince as an auspicious ceremonial costume worn at the wedding in the year of Imo.

This study is focused on the elucidation of efficient and correct marking methods by comparing and analyzing marker efficiency depending on the marking job condition such as interval of checking-pattern and marker orientation using woman's Jacket and Slacks. Research Method intended to compare the marking efficiency of Jacket and Slacks, check-less and check- patterned materials with the intervals of $1.5{\times}1.5cm$ and $5{\times}5cm$ were selected. First, in the comparison of marking efficiency depending on check-pattern interval, regardless of the direction of marker position, single-item makers and set-item makers, the efficiency of check-less materials was higher than those of check-patterned materials and increasing the intervals decreased marking efficiency and vice versa. Marking efficiency of Slacks was less influenced than marking efficiency of Jacket by check-pattern interval. Second, in the comparison of marking efficiency depending on the direction of marker position, regardless of check-pattern interval and number of maker pieces, the efficiency of nap-up-and-down position was higher than those of nap-one-way position. Third, the marking efficiency of single-item was more effective than one of set-item in all working condition except nap-one-way position in checkless materials.

Objective : Extracranial supra-aortic dissections (ESADs) with severe stenosis, occlusion and/or pseudoaneurysm presents potential risk of stroke. Endovascular stenting to reconstruct non acute phase ESADs (NAP-ESADs) is an alternative to anticoagulant or antiplatelet therapy. However, its feasibility, safety and efficacy of stenting in NAP-ESADs is unclear. This study aims to investigate the long-term outcomes of the feasibility, safety and efficacy of stenting in NAP-ESADs. Methods : Seventy-four patients with 91 NAP-ESAD vessels with severe stenosis, occlusion and/or pseudoaneurysm presents potential risk of stroke who underwent stent remodeling were enrolled into this respective study from December 2008 to March 2020. Technical success rate, complications, clinical and angiographic results were harvested and analyzed. Results : Success rate of stent deployment was 99% (90/91) with no procedural mortality or morbidity. Transient ischemic attack occurred in three patients during operation (4.1%, 3/74). Asymptomatic embolisms of distal intracranial vessels were found in two patients (2.7%, 2/74). One hundred and forty-two stents deployed at 85 carotid (135 stents) and six vertebral (seven stents) vessels. Six stent types (Wingspan, 28/135, 20.7%; Solitaire, 10/135, 7.4%; Neuroform, 8/135, 5.9%; LVIS, 2/135, 1.5%; Precise, 75/135, 55.6%; Acculink, 12/135, 8.9%) were deployed at carotid arterial dissection while two types (Wingspan, 5/7, 71.4%; Solitaire 2/7, 28.6%) at vertebral arterial dissection. Digital subtracted angiography (56%, 51/91), computational tomography angiography (41.8%, 38/91) and high resolution magnetic resonance imaging (2.2%, 2/91) were adopted for follow up, with a mean time of 17.2±15.4 months (5-77). All patient modified Rankin Scale scores showed no increase at discharge or follow-up. Angiographically, dissections in 86 vessels in 69 patients (94.5%, 86/91) were completely reconstructed with only minor remnant dissections in four vessels in four patients (4.4%, 4/91). Severe re-stenosis in the stented segment required re-stenting in one patient (1.1%, 1/91). Conclusion : Stent remodeling technique provides feasible, safe and efficacious treatment of ESADs patients with severe stenosis, occlusion and/or pseudoaneurysm.

Individual vacuum pressure method is soft ground improvement technique, in which a vacuum pressure can be directly applied to the vertical drain board to promote consolidation and strengthening the soft ground. This method does not require a surcharge load, different to embankment or pre-loading method. In this study, given the inner displacement of the ground where the individual vacuum pressure is applied, this dissertation aimed to reproduce the state of stress in the ground that is subject to the constraints created by the depth of improvement area. Modified Cam Clay theory which made it possible to take into account the isotropic displacement of the ground was applied to the NAP-IVP used simulation; the conception of equivalent permeability proposed by Hird was also applied so that the 3-dimensional real construction effect of drain materials could be reflected in the analysis.
