합천(陜川) 밤마리와 오광대(五廣大),들놀음 소고(小考)

The summary of this paper is as follows: 1. There are two theories on the origin of Ogwangdae and Dulnorum. One is that it was originated at Bammari in Hapchon in the late nineteenth century. The other says that it dates back older than that. Our analysis in this paper is based on the data in the late nineteenth century because no data older than that has remained. 2. Bammari used to be an important place in the watercourse along the akdong River. When a market in its river port prospered, a group called Daegwangdae came to stay under the patronage of the merchants and disseminated their mask-plays in Pusan and the South Kyongsang province. However, as the market which opend every five days was on the decline around 1925, they disappeared. 3. The mask-plays of Pusan and the South Kyongsang province which were inherited in 1870`s had been performed in about 20 areas with common as well as different features. However, only five of them have been preserved now as intangible cultural properties. 4. Obang Sinjang-mu, the opening act, is a dance for the ritual that purifies the playground and wishes the safe completion of the play. However, it is performed only in Gasan Ogwangdae now. 5. The Leper act and the Yongno act in Dulnorm of Pusan and in Ogwangdae of the South Kyongsang province are not found in the mask-plays of other provinces. Their characteristic feature is the heavy satire and insult of the Yangban class.

This study proposes a phase change material based radiant cooling panel with thermoelectric modules (PCM-TERCP) and evaluate its performance characteristics during melting process of phase change materials in designed condition. The PCM-TERCP consists of phase change materials (PCMs), thermoelectric modules (TEMs) and aluminium panels. TEMs operate to freeze the PCM, and PCM stores the cooling thermal energy to maintain the constant surface temperature of the panel for radiant cooling. The main purpose of thermal energy storage systems is shifting the cooling season’s electricity consumption from day-time to night-time. Therefore, PCM-TECRP can implement the off-peak operation and it is expected that energy can be saved. Therefore, we constructed the mock up model of PCM-TERCP to identify the factors that affect the discharging process of PCM-TERCP. The mock up model of PCM-TERCP was made of top aluminium panel with three TEMs attached on the upper surface of the top panel, and a heat sink was attached on the hot side of each TEM to remove the heat, and two PCM pouches were installed between top and bottom panel. In addition, the melting temperature of PCM and target surface temperature of bottom panel were designed to be 16℃. Also, the room temperature was set to be 24℃. As a result, radiative cooling was operating a temperature range of 16-20℃ for 3 hours.

Building-integrated photovoltaics (BIPVs) are among the most promising renewable energy systems for densely populated urban. However, BIPV system showed some critical defects in efficiency which the limited insolation and the absence of heat dissipation structure. Therefore, resolving these shortcomings requires system solutions that can increase the PV efficiency or utilize heat sources to improve system efficiency. The phase change material is one of the promising ways to improve the PV efficiency or using the heat source. However, owing to problems caused by the low thermal conductivity of PCMs, many studies have combined heat fins and nano-fluid PCMs. In addition, some studies have proposed and investigated methods of heat recovery combine TEGs, which can generate electric power depending on the temperature difference without additional equipment. However, TEGs also have the disadvantage of very low power generation efficiency if they do not achieve a high temperature difference. Therefore, in this study, to address the limitations of each application, a BIPV combined with a PCM and TEG (BIPV-TEG-PCM) is proposed. Herein, the appropriate phase change temperature of the PCM and heat pipe design in the PCM container were analyzed through computational fluid dynamics(CFD)-based simulations.

This study proposes the thermoelectric module radiant cooling panel integrated with phase change material (PCM-TERCP) and analyzes its thermal behavior and performance characteristics during the active and cooling process of phase change materials in design conditions. In this experiment, the paraffin was used as phase change material. PCM-TERCP has two operation mode: one is the passive cooling mode and another is active cooling mode. Thermoelectric modules (TEMs) operate to freeze the PCM and cool the target zone during the active cooling mode, and the PCM stores the cooling thermal energy to maintain the constant surface temperature of the panel for radiant cooling during the passive cooling mode. The melting temperature of paraffin, which is the target surface temperatures of PCM-TERCP, was designed to be 16°C, to prevent the condensation. As a result, the empirical model was developed to predict the active and passive cooling time and cooling capacity in each mode of the PCM-TERCP. Consequently, the PCM-TERCP can offer the cooling passively as 1-8 hours and 30-97 W/m2, and freeze during the in active cooling mode following the different conditions without the TEMs operating.

In this paper I have divided, cur ritual for rain into two types: governmental and nongovernmental, and have studied diachronically the distinctive quality and significance of the ritual according to the style or performance, the location, and the object prayed to. 1) Each period emphasizes different aspects of the ritual`s performance. 2) Some of the customs associated with praying for rain have undergone changes in their original significance, and have merged into other types later on. 3) The ritual had been a public ceremony from the Three Kingdoms Period up to the Yi Dynasty, but afterwards it became nongovernmental, and kings and government officials ceased to participate in it. 4) However, there are some aspects of the ritual which have not been moditied since the Three Kingdoms Period. 5) The locations of the ritual performance, which had varied until the close of the Yi Dynasty, have been limited, and the objects of worship also have been limited; however, through all ages, tithe dragon has been worshipped. Then though the ritual or praying for rain has declined with the development of science, the need for both the community feeling resulting from the voluntary participation on the part of the country people and the sense of religious purification will not disappear.

Thermoelectric module (TEM), non-vapor-compression heat pumps, are of interest as substitutes for conventional vapor-compression heat pumps. However, the heat exchange effectiveness and performance of TEMs for application to heating, ventilation, and air conditioning (HVAC) systems had been less studied. The purpose of this research is to propose the system configuration of TEM heat pump unit and to predict the heat exchange effectiveness in air heat pump system using TEM. The proposed system is composed by flat plate fin array that is heat exchanger integrated TEM for cooling and heating. The experiments were conducted to predicting the cooling and heating heat exchange effectiveness by collecting performance data. The performance data are composed by the inlet air fluid temperature, air flow rates at each side, heat exchange area, and input direct current (DC) to the TEM. Outlet fluid temperatures and TEM surface temperature are also measured for deriving the heat exchange effectiveness. Design parameters had significant impact on the heat exchange effectiveness of the flat plate heat exchanger integrated TEM for air cooling and heating. Consequently, in this paper, the influence of the five input parameters (air temperature at both side, air flow rate at both side, current) were analyzed. In proposed unit, the heat exchange effectiveness of hot and cold sides was 0.41 to 0.59 and 0.23 to 0.30, respectively
