Reddish brown clay-silt sediments covered granitoid weathering crust in the Jangdongri area, Naju, Korea. Mineralogical and geochemical properties of the ~2 m sediment section were investigated. The sediments were composed mainly of quartz (50%) and clay minerals (45%) with minor contents of K-feldspar, goethite, hematite, and gibbsite. The clay minerals were illite, illite-smectite mixed-layers, vermiculite, hydroxy-Al vermiculite, kaolinite, and halloysite. Mineral composition varied little through the section with the minor upward enrichment of plagioclase and chlorite. Abundant illitic clay minerals indicated the remote source of the sediments because clays derived by granite weathering in Korea were dominated by kaolin minerals. A comparison with the mineral composition of Asian dust (Hwangsa) suggested that plagioclase and K-feldspar disappeared by chemical weathering after deposition, resulting in the quartz and clay-rich sediments. Plagioclase and chlorite altered to kaolin and vermiculite, respectively. Goethite and hematite derived by the weathering of iron-bearing minerals stained the sediment to reddish brown color. The mineralogical and geochemical properties of the reddish brown clay-silt sediments were consistent with those of eolian deposits identified in Korea, supporting eolian origin of the Jangdongri sediments, requiring future confirmation including age dating and isotopic analysis.

Stone-cultural-properties, distributed in Naju, Hwasun and a part of Jangheung, have been investigated and studied on the characteristics, rock weathering and phases in the geological and conservational points of view. The properities involve pagoda and twelve stupas, four stone-buddha, three stone monuments, two stone-lantern, four stone-Jangseung, one and flag-pole. The rocks used are mainly pebble-bearing tuffaceous rocks of the Cretaceous age which are widely distributed in the area. However, granites are also used in some properties. These rocks are strongly influenced by weathering and pervasive moss. The mottled rock surfaces in some properties are in colors due to pervasive moss different. Parts of some cultural properties are broken which results in structurally unstable. Cultural properties in the area are relatively well conserved at the earth consolidated by ramming and by iron fence. However some cultural properties are partly repaired by using other hinds of rock phases which results in different colors in weathered rock surface. For conservation, rock phases, weathered surface colors, and relationships with original parts must be scientifically considered in repairment forward.

In order to predict frostfall, nocturnal cooling rate and air temperature changes were analyzed on days with and without frost when the maximum temperature was lower than $20^{\circ}C$. In general, the nocturnal cooling rates on frosty days were higher than those on non-frosty days. The cooling rates averaged from 19:00 to 24:00 on frosty and non-frosty days were $1.7^{\circ}Ch^{-1}$ and $0.7^{\circ}Ch^{-1}$ respectively. As expected, the nocturnal temperature on frosty days was lower than that on non-frosty days. Especially, the midnight air temperature averaged about $3.9{\pm}1.5^{\circ}C$ on frosty days, which was lower than that on non-frosty days (i.e., $10.1{\pm}2.9^{\circ}C$). The discriminant analysis using three independent variables (i.e., total cloud amount, air temperature at 24:00, and 5-day rainfall amount) successfully classified the presence of frost with 87% accuracy.

The sword with a ring pommel, which was excavated from the first stone chamber of the ancient tombs of Jeongchon Village in Naju, is a sword with a pentagon undecorated ring pommel consisting of a mother sword and two child swords. The sword with an undecorated ring pommel of Jeongchon comprises a ring pommel, a hilt, a knife, and a knife end decoration. This sword was coated with lacquer. The ring pommel is an iron frame covered with silver plate; however the silver tarnished into a light purple due to silver chloride corrosion, and iron corrosion originated from the inside is visible on the surface. Silver chloride corrosion is produced when silver objects are exposed to water, dissolved salts, and dissolved chloride ions when in a buried state. It changes objects into powder, making it difficult to preserve original shapes. The other silver artifacts found in the Jeongchon ancient tombs show similar signs of corrosion. The results of X-ray irradiation and a CT analysis showed that the sword had a ring at the end of the handle, a T-shaped hilt, and was probably connected to the handle end of a knife. If the shape of the mother sword can be inferred from the child swords, the mother sword had a ring pommel, decorations of the handle, covered with silver plate, and a gold ring and a silver line wound around the handle. It is assumed that the ring pommel was connected to the knife by welding because no holes were observed. The end decoration of the knife was made by using an iron plate formed into a shape, half covered by silk, and the other half decorated with silver plate and a gold ring. The sword with an undecorated ring pommel excavated from the ancient tombs of Jeongchon Village comprises the metals of gold, silver, and iron, and includes features of Baekje, Silla, and Gaya, which highlights the influence of surrounding historic sites and various cultures.

The purpose of this paper is to examine the unmanned life and poetic world of Ilong Choehuilyang. Choehuilyang is uninhabited and rarely left 227 poems and being recognized for his poetic achievements by later writers. Therefore, it would be meaningful to look at Choehuilyang's poetic world in the point of studying the unmanned poetry system. In Chapter 2, I looked at life as a base stage to understand Choehuilyang. Choehuilyang from his youth while studying at the age of 21, but turned to 武科. This is due to the gauntlet of the family who does not care about the 文武, Choehuilyang's grand physical condition and the resulting unattended temperament. Choehuilyang passed the exam in the past. And he won the war seven times under General Admiral Yi. However, when Admiral Yi Sun - shin was killed in Noryang, Choehuilyang returned to his hometown. After that, he died without going out until he was 92 years old. In Chapter 3, we examined Choehuilyang's spoetic world based on Chapter 2. Choi 's poetry can be divided into revealing the temperament of the unmanned, living peacefully in his hometown after returning home, and revealing his concern for the country. The poems revealing the unattended temperament are created by sensuous sheer or direct narrative when they are on the battlefield, when they watch the war after returning home. Peaceful life in Kangho was created in Naju, the hometown. And the poem that worried about the country was created by seeing the sick horan. I hope that the research that has been discussed so far will help to understand Choehuilyang's life and world.

Sun-induced fluorescence (SIF) retrieval using remote sensing technique has been used in an effort to understand the photosynthetic efficiency and stress condition of vegetation. Although optical devices and SIF retrieval methodologies were established in order to retrieve SIF, the SIF measurements are domestically sparse. SIF data of paddy rice w as measured in Naju, South Korea from June 10, 2020 to October 5, 2020. The SIFs based red (O2A) and far-red (O2B) w ere retrieved using a spectral fitting method and an improved Fraunhofer line depth, and photosynthetically active radiation was also produced. In addition, the SIF data was filtered considering solar zenith angle, saturation conditions, the rapid and sudden change of solar irradiance, and sun glint. The provided SIF data can help to understand a SIF product and the filtering method of SIF data can contribute to producing high-quality SIF data.

We report the case of a 32-year-old woman presenting with intermittent chest pain resulted from a migratory acupuncture needle. The patient received acupuncture treatment approximately 3 years prior to this presentation, for the treatment of chronic left shoulder and lumbar pain after delivery. Chest radiography revealed a retained needle in the lingular segmental area. Video-assisted thoracoscopy was then used to remove the migratory acupuncture needle attached between the lingular segmental lobe and the pericardial fat. The patient recovered without complications and was discharged home.

Small apartment housings in Korea are dissatisfied due to the growing areas and changing lifestyle of the residents. Many of them currently confronted with slum areas and kinds of housing stock accumulated much more in Korean contexts. An extention of the existing small houses could be an adaptation model to the increasing requirement standards of the house residents. The new model could support diverse identification of the dwelling model in a settlement and many residents could be satisfied with the settlement. This paper deals with the unification typology of two dwelling units to one in order to remodel existing small apartment houses on the 15-pyung areas (N type) constructed by Korea National Housing Corporation in Naju. The proposed type of the merging of the dwellings remove concrete panel walls, make a path through balcony and attach a living areas to the front of the houses in order to make a circulation between the dwellings. A stair hall can be located in-between or inside the merged houses. It can also enhance privacy against conflictive activities in a house and possibly provide space appropriate for three-generation living. It can be devided for the multi-family use. Finally, the merging types of two dwelling units into one can be used as a device to get rid of the monotonous characteristics and gain diversity in the declining stock housing.
