Deokjin Park in Jeonju City was the site of a pond during the Koryo Period. Although Jeonju City has developed rapidly in modem times, Deokjin Pond was preserved and was developed into a park It can be theorized that Deokjin Pond's latent character has made it possible for it to adapt to the changes it has undergone throgh the years. In this study, the placeness of Deokjin Park is determined by examining its role in the adaptation process. Placeness can be determined by examining the objective character of a certain environment and the subjective experience related to it. For this paper, documents about the history of Deokjin Park were examined so that the facts related to it could be established. In addition, a number of Jeonju citizens were asked about their memories of Deokjin Park since memories reveal people's subjective experiences. The results of this study can be summarized as follows. Deokjin Pond is an ideal space for Feng Shui. It is a holy place because the tomb of the founder of the Chosun Dynasty is close to it. In addition, it has scenic value as it is part of the Jeonju Palkyoung (eight sceneries). To this day, we can see people washing their hair in the pond, proof that Deokjin Pond is still the subject of folk beliefs. When Korea was under Japanese rule, Deokjin Pond became Deokjin Park because of its ideal location, scenic value, and grand possibilities as an amusement center. Over the years, though its scenic value decreased after the death of its pine trees. Jeonju City, however, was able to revive the park's charm though a series of renovation projects and through the addition of several facilities. Deokjin Park is now surrounded by many cultural buildings. The significance of Deokjin Park can be expected to evolve with these changes. This study helps to predict the future of Deokjin Park and to elucidate the importance of landscape architecture from the point of view of an "evolving place."

To know of the biological basic method that can improve the environment of the organisms that inhabit at Deokjin Park. We studied the flora and the fauna in Deokjin Park on June, 1996. The study was surveyed and researched according to the items floras, phytoplanktons, insects and vertebrates. The floras are composed of eleven varieties, one forma, eighty-three species, eighty-four genera and forty-nine families. In the lake of Deokjin Park, the dominant species were Nelembo nucifera and Spirodela polyrhiza. The authors thought that those species be artificially excluded in winter for the improvement of the quality of water. The phytoplanktons were composed of forty genera, eighteen families, ten orders and six classes. Among those, Anacystis(=Microcystis) and Anabaena that make eutrophication, were distributed in the lake of Deokjin Park. The fauna of insects were composed of forty-one species, thirty families and eleven orders. The authors observed seven species of fish, two species of amphibian, three species of reptile, seven species of the bird and one species of mammal. Among those, Bull-frog and Blue-turtle as exotic species must be excluded by artificial methods for the other native organisms of the lake of Deokjin Park.

In this study, we investigated the restoration possibility of the old streams by enhancing the rainwater infiltration in the watershed of Deokjin Park, Jeonju City. This study was performed by modeling groundwater discharge to the streams under various conditions. We assessed the amount and location of groundwater recharge enhancement to restore the streams and evaluated whether the baseflows of the restored streams are sufficient to keep the water ecosystem of the Deokjin Pond. The results show that the baseflow of the streams can persist for a longer time even during the dry season when the rainwater drainage system is recovered similarly to the those before development using low impact development (LID) techniques. The enhancements of recharge in the headwater area, which is the area around the zoo and Daeji Village in the Deokjin Park watershed, is useful to increase the baseflows of the downstream reaches. Furthermore, spreaded recharge over a widespread area is better to prevent the streams from drying than the intensive recharge at a few sites.

This survey was performed to monitor the spread of specific mosquito-borne pathogens at Jeonbuk. The frequency of occurrence of mosquito borne pathogens including Japanese encephalitis virus, West Nile virus, Zika virus, and yellow fever virus was assessed by collecting mosquitoes twice a month from March to December 2021 from various areas in Jeonbuk. A total of 15,975 mosquitoes from 15 species and 7 genera were collected. The highest number of 9,116 mosquitoes (trap index: TI, 506.4) were collected in the Wanju cattle pen, followed by the habitat for migratory birds and the downtown area in Jeonju. In the Gunsan habitat for migratory birds, 3,217 mosquitoes (TI, 178.7) were collected in the reed fields, 356 (TI, 19.7) in the men's toilets, and 1,948 (TI, 108.2) in the women's toilets. In Jeonju, 677 mosquitoes (TI, 37.6) were collected in the Deokjin park, 358 (TI, 19.8) in the Deokjin-gu office, and 303 (TI, 16.8) at the Jeonbuk National University. The largest population of mosquitoes was collected in the men's toilets in Gunsan and the Deokjin Park in downtown Jeonju. The results of the RT-PCR confirmation to determine the pathogen infection of the collected mosquitoes were all negative. These results provide a basis for tackling integrated mosquito-borne diseases in the Jeonbuk region.

This survey is to find out children' needs of D children's park to remodel into a new one and their common opinions about the child playground, and to contribute these results to drive alternative plans. This park is very old and located in detached residential area, Wooa-dong, Deokjin-gu, Jeon-city. The survey was performed by a questionnaire, and the questionnaire was based on the relative literature reviews and was redesigned by researchers. Data were collected from 198 children, who had attended elementary school in Wooa-dong. By analyzing those data, findings were as follows: 1) Play experiences of D children's park were very important for children, so they remembered it. Above all, they remembered the perceptions of D children's park through playing on the playground facilities and the communication with their friends at that time. 2) Children would like to play creatively with facilities, but they need the traditional play facilities like a slide and a swing. So, it would be important for D children's park to plan well with the good facilities, and even it was mentioned in the literature reviews. The planning of park should be checked as an adventure playground, which can allow children to play creatively and with variety, however it should be still considered with some traditional playground facilities.

It is well known that the inflow of rainwater and the infiltration of groundwater to sewerage (I/I) increase the sewage and burden sewage treatment plants and lower their treatment efficiency. Therefore, it is important to estimate the amount of I/I. In this study, well groundwaters, public water supplies (PWSs), and sewage and rainwater channels were investigated to check whether oxygen and deuterium isotopes could be used as a tool for I/I estimation. This study shows that the isotopic composition of PWS in Jeonju area is very consistent over time and distinctly lighter than the circulating local rainwater (CLR) because it is supplied from Yongdam Dam, which is located about 40 km inland to the east in the mountainous area. Considering the fact that sewage mostly originates from the PWS, we could calculate the amounts of CLR in the sewerage from a monitoring station using unaffected rainwater and tap water as mixing end members. The calculation revealed that the CLR fraction ranged from 50% to 90% depending on observation time. This is well supported by the dilute natures of the sewages at the station. The fraction of PWS in investigated well waters were about 46%, indicating that leaking of PWS is very serious and is an important groundwater source in the study area. Since the infiltration of such groundwater may not alter the isotopic composition of sewage significantly, the actual I/I would be much greater than the calculated ones.

Two recombinant bacteria containing luxAB showed an increased tolerance to stresses associated with lyophilization, when the cells were freeze-dried in the presence of trehalose. In the case of a recombinant, UV2, only $2.5\%$ of the original bioluminescence and $2.7\%$ of the cell viability were restored after 4 h of freeze-drying without trehalose, which implies that the cells were heavily damaged during the dehydration. To improve these losses, trehalose was added before freeze-drying using different modes. Trehalose increased the bioluminescence and the viability of freeze-dried UV2 under all conditions tested, and it was also observed that the addition of trehalose to the cultures (final concentration of 0.08 M) for 15 min before the freeze-drying resulted in the restoration of $45\%$ of the original bioluminescence and $50\%$ of the cell viability. Trehalose also showed a similar efficacy with the other luminescent recombinant, YH9. Therefore, it was tentatively concluded that trehalose played a role as a protective agent in the freeze-drying of bacterial cells.
