The urban regeneration project linked to tourism is to change the local environment by transforming a residential area into a commercial space. In Gunsan, urban regeneration Project is in progress from 2009 to the present. In order to study the change in residents’ perception, a text analysis method was performed using a mook 「People in Gunsan」 published in 2016, 2018, and 2020. 14,249 words were collected to analyze their frequency and relationship. As a result of the text analysis, it is confirmed that local residents commonly recognize the increase of tourists, the outflow of natives, and the influx of outsiders for commercial activities. They present opinions on future changes as well as memories of urban spaces, along with the progress of various urban regeneration projects.

Fuji Farm Community was created by reclamation as a part of Japanese settlement to solve food and population problems in Japan and promote colonialization. This Japanese immigrants’ village in Gunsan, 31 villages and 297 houses were built in three stages from 1924 to 1930. The village was also called by the name of original hometown. In this study, the architectural plan of standard house was drawn by auto-cad based on literature research and field survey. The characteristics of Fuji Farm Community house are as follows: First, the typical house type was built applying the standard for Fuji Farm Community house and 10 houses were assembled. Second, Fuji Farm Community house was composed of spaces such as tatami-room, ondol-room, kitchen, and storage side by side. Third, Ondol rooms were installed reflecting Korean climate and local condition. Fourth, it was renovated and expanded in accordance with the actual usage and Korean residents’ life style after liberation. Therefore, Fuji Farm Community house as Japanese immigration village is an origin of the present town and has a value of assets representing local identity.

In some portions of nuclear piping systems, stratification phenomena may occur due to the density difference between hot and cold stream. When the temperature difference is large, the stratified flow under diverse operating conditions can produce high thermal stress, which leads to unanticipated piping integrity issues. The objectives of this research are to examine controvertible numerical factors such as model size, grid resolution, turbulent parameters, governing equation, inflow direction and pipe wall. Parametric threedimensional computational fluid dynamics analyses were carried out to quantify effects of these parameters on the accuracy of temperature profiles in a typical nuclear piping with complex geometries. Then, as a key finding, it was recommended to use optimized mesh of real piping with the conjugated heat transfer condition for accurate thermal stratification analyses.

In the undergoing urban regeneration projects, local archiving is an essential process for local regeneration and a basic method to complement academic research and field survey. Local archiving is carried out through the following process: [Step 1] Basic Survey and Community Networking → [Step 2] Field Survey → [Step 3] Verification & Investigation → [Step 4] Utilization of Archiving Data. First, local archiving makes possible to access the integrated result. Second, local archiving with the common memories of the local community, could enhance understanding of the local history and culture, establish a local identity and to solidify the awareness of local assets. Third, it contributes to the local community by sharing the archiving results with the local community and using them for the urban regeneration projects. Recently, in the course of urban regeneration project, archiving was conducted for Gaewon and Michang villages located in Gunsan to examine the formation and change of Fuji Farm Community. Agricultural immigration of the Fuji Farm Community was carried out in order to construct a new Japanese ideal village. Through reclamation in the 1920s, a group of Japaneses from various districts migrated into the area generated in the Fuji Farm. Gaewon and Michang village consisted of 30 households in that period. After liberation, the empty houses and lands were sold to Koreans, and the residents were mainly engaged in agriculture. With the industrial complex in the 1980s, the village developed as a residential area for industrial complex. However, since the 2000s, the village declined and residents left due to the environmental pollution occurred from the industrial complex. At the beginning of the village, the standard houses were built in units of 10 buildings. The standard house, within a mixture of Japanese and Korean housing styles, consisted of tatami-room, ondol-room, kitchen, toilet and storage arranged in parallel. Spatial changes have occurred continuously due to the increase of population, transition to Korean life style and pursuit of living convenience.

Janghang Smelting Factory built and operated large-scaled company housing complex for employees’ welfare from the Japanese colonial period until 1990s. Janghang Smelting Factory company housing complex consists of dormitory for singles and row houses for family. During the Japanese colonial period, 60 buildings and 153 units were constructed, such as baikma-house, Moogung-house, Gyeryong House and Jangam-house. After liberation, the old houses were demolished and rebuilt. In the 1990s, due to the change of housing culture, the company house was converted into an apartment type, in middleof 2000s the old company house houses were demolished and disappeared with decline of modern industry. The company house shows the transition of Janghang as a modern city.

목 적: 항문암으로 근치적 목적의 동시 항암화학 방사선치료를 받은 환자들을 대상으로 치료반응의 예측인자, 생존율과 관련된 예후인자를 알아보고자 하였다. 대상 및 방법: 전남대학교병원에서 1993년부터 2008년까지 병리조직학적으로 항문의 편평상피세포암으로 진단받고 근치적 목적의 동시 항암화학 방사선치료를 받은 42명의 환자를 대상으로 후향적으로 분석하였다. 환자들 나이의 중앙값은 61.5세(39∼89세)였고 방사선량의 중앙값은 50.4 Gy (30.0∼64.0 Gy)였다. T병기 상 2기 이하였던 환자는 총 36명(85.7%)이었다. 영역림프절전이는 14명(33.3%)에서 있었다. 항암화학요법으로는 5-fluorouracil, mitomycin 병행요법으로 치료받은 환자가 36명(85.7%)이었고 나머지는 5-fluorouracil, cisplatin 병행요법을 받았다. 결 과: 전체 환자의 추적관찰기간의 중앙값은 62개월(2∼202개월)이었다. 5년 전체생존율, 국소영역제어율, 무병생존율, 무장루생존율은 각각 86.0%, 71.7%, 71.7%, 78.2%였다. 전체생존율과 관련된 인자로 단변량분석에서는 Eastern Cooperative Oncology Group (ECOG) 수행능력과 완전관해여부가 유의하였고 다변량분석에서는 ECOG 수행능력만이 유의하였다. 국소영역제어율, 무병생존율과 무장루생존률에 관련된 인자는 단변량이나 다변량분석 모두 유의한 인자는 없었다. 치료 후 완전관해 여부와 관련하여 유의하게 예측할 수 있는 인자는 없었다. 국소영역 재발은 7명에서, 원격전이는 1명에서 발생하였다. 전체 환자에서 평가가 가능하였던 급성 부작용으로 3도의 피부염이 4명(9.5%), 2도는 22명(52.4%)에서 발생하였다. 결 론: 본 연구에서 항문의 편평상피세포암에 대한 근치적 목적의 동시 항암화학 방사선치료로 양호한 생존율을 얻을 수 있었고, 특히 ECOG 수행능력이 1 이하인 환자의 생존율이 유의하게 높았다. 그러나 치료 후 종양반응을 예측할 수 있는 유의한 인자는 없었다. Purpose: To evaluate the predictive factors for treatment response and prognostic factors affecting survival outcomes after concurrent chemoradiotherapy (CCRT) for patients with anal squamous cell carcinoma. Materials and Methods: Medical records of forty two patients with histologically confirmed analsquamous cell carcinoma, who had complete CCRT between 1993 and 2008, were reviewed retrospectively. Median age was 61.5 years (39∼89 years), and median radiotherapy (RT) dose was 50.4 Gy (30.0∼64.0 Gy). A total of 36 patients had equal to or less than T2 stage (85.7%). Fourteen patients (33.3%) showed regional nodal metastasis, 36 patients (85.7%) were treated with 5-fluorouracil (5-FU) plus mitomycin, and the remaining patients were treated by 5-FU plus cisplatinum. Results: The median follow?up time was 62 months (2∼202 months).The 5-year overall survival, locoregional relapse-free survival, disease-free survival, and colostomy-free survival rates were 86.0%, 71.7%, 71.7%, 78.2%, respectively. Regarding overall survival, the Eastern Cooperative Oncology Group (ECOG) performance status and complete response were found to be significant prognostic factors on univariate analysis. For multivariate analysis, only the ECOG performance status was significant. No significant factor was found for locoregional relapse-free survival or disease-free survival and similarly for treatment response, no significant factor was determined on logistic regression analysis. There were 7 patients who had local or regional recurrences and one patient with distant metastasis. The only evaluable toxicity in all patients was radiation dermatitis of perianal skin (grade 3), which developed in 4 patients (9.5%) and grade 2 in 22 patients (52.4%). Conclusion: This study revealed that patients with a performance score of ECOG 0-1 survived significantly longer than those with a poorer score. Finally, there was no significant predicting factors tested for treatment response.
