Objective : In this study, we investigated the prevalence of depression and its impact on the healthrelated Quality of life (HRQoL) of the patients with End-Stage Renal Disease (ESRD) on Hemodialysis. Method : The Quality of life (QOL) of patients was evaluated by HRQoL Questionnaire, "Medical Outcome Survey 36-Item Short Form Health Survey Korean Version (SF-36-K)". The patients on Hemodialysis in ESRD, were chosen from the hemodialytic room at Wonkwang University and Jeongeup-Asan Hospital. The number of patients was 95 (64 from Wonkwang University Hospital and 31 from Jeongeup-Asan Hospital) and all of them were above 19 years old. We performed various investigations to find a statistical correlations between HRQoL and physical & psychosocial factors such as the demographic characteristics, clinical characteristics (hemoglobin level and albumin level etc), and the score of Beck's depressive inventory (BDI). Results : The HRQoL value of patients on hemodialysis in ESRD is far poorer than the HRQoL reference value of Koreans and Americans, who are in normal healthly. The prevalence of depressive symptoms by BDI of the ESRD patients on hemodialysis is 68.6%, and age and depression have negative correlations with HRQoL of the patients. However, education level, serum albumin level, and social support have positive correlations with HRQoL. The patient group with depression has significantly poorer HRQoL than the group without depression. Conclusion : The HRQoL of ESRD patients on hemodialysis is not good in both physical and mental aspects. The prevalence of depression is very high and depression has negative impact of HRQoL of patients. Based on our study, it is essential to accompany with therapeutic Strategy to improve the HRQoL of ESRD patients on hemodialysis.

김형준,조천형,이경구,Kim, Hyung-Joon,Cho, Chun-Hyung,Lee, Kyung-Ku 한국방사성폐기물학회 2008 방사성폐기물학회지 Vol.6 No.2

후행 핵연료주기 경제성 평가는 추정 비용의 불확실성, 평가 대상기간의 장기성, 적용 할인율에 따른 계산결과의 변동성 등 많은 불확실성을 내포하고 있기 때문에 평가기관 또는 평가자에 따라 그 결과가 서로 상이하다. 본고에서는 지금까지 수행된 주요 경제성 평가 연구들을 조사/분석하여 그 특징과 한계를 알아봄으로써 현재 국내에서 추진되고 있는 사용후핵연료 공론화 및 후행 핵연료주기 정책 연구 추진에 기초자료로 활용될 수 있도록 하고자 하였다. 분석 결과 사용후핵연료 재활용 옵션에 비해 직접처분 옵션이 유리하나, 입력 자료로 사용된 파라미터 값에 따라 결과의 불확실성이 많이 나타나 이 부분에 대한 추가적인 연구가 필요하다는 사실을 알 수 있었다.

목적: 혈청 비타민 C 수치는 체내 항산화상태를 나타내는 지표로서, 암환자에서는 정상인에 비해 감소되어 있다. 하지만, 이 지표가 말기암환자에서 어느 정도 감소되어 있고, 그 감소에 어떤 요인들이 관련되는지에 대한 연구는 매우 드물다. 방법: 두 개 기관의 완화의료병동에 입원했던 암환자 65명을 대상으로 하였다. 환자의 나이, 성별, 암의 종류, 기능상태, 임상증상, 완치 목적의 암 치료력, 그리고 혈청 비타민 C를 포함한 혈액검사 자료를 수집하였다. 혈청 비타민 C 수치의 사분위수를 기준으로 두 군(3사분위수 이하 vs. 4 사분위수)으로 분류한 후 각 군의 차이를 비교하였고, 단계적 다중 로지스틱 회귀분석을 통해 혈청 비타민 C 수치와 관련된 인자를 확인하였다. 결과: 대상자의 혈청 비타민 C의 평균은 $0.44{\mu}g/mL$이었으며, 대상자 전체가 비타민 C 결핍에 해당되었다. 단변량 분석에서는, 비폐암 환자이거나(P=0.041) 발열이 있는 환자(P=0.034)에서 낮은 혈청 비타민 C 수치를 보였다. 폐암, 발열, 삼킴곤란, 호흡곤란, C 반응단백, 그리고 항암화학요법 등의 잠재적인 인자들을 보정한 다변량 분석에서, 낮은 혈청 비타민 C 수치를 나타낼 가능성은 항암화학요법을 받은 군에서 그렇지 않은 군에 비해 3.7배 높았고(P=0.046), 발열이 있는 군에서 그렇지 않은 군에 비해 7.22배 높았다(P=0.020). 결론: 말기암환자에서 비타민 C 부족은 매우 심각하였고, 항암화학요법 치료력과 발열이 관련 있었다. Purpose: Serum vitamin C is one of the indicators for antioxidant levels in the body and it is lower in cancer patients compared with the healthy population. However, there have been few studies on the levels of serum vitamin C in terminally ill cancer patients and related factors. Methods: We followed 65 terminal cancer patients who were hospitalized in two palliative care units. We collected data of age, sex, cancer type, functional status, clinical symptoms, history of cancer therapy, and various laboratory findings including serum vitamin C level. Patients were categorized into two groups according to the quartile of serum vitamin C level (Q1-3 vs. Q4), which were compared each other. Stepwise multiple logistic regression analysis was used to identify factors related to serum vitamin C levels. Results: The mean serum vitamin C level was $0.44{\mu}g/mL$, and all patients fell into the category of vitamin C deficiency. Univariate analysis showed that The serum vitamin C level was lower in non-lung cancer patients (P=0.041) and febrile patients (P=0.034). Multivariate analysis adjusted for potential confounders such as lung cancer, fever, dysphagia, dyspnea, C reactive protein, and history of chemotherapy demonstrated that odds for low serum vitamin C level was 3.7 for patients receiving chemotherapy (P=0.046) and 7.22 for febrile patients (P=0.02). Conclusion: Vitamin C deficiency was very severe in terminally ill cancer patients, and it was associated with history of chemotherapy and fever.

저자들은 2주간의 간헐적 상복부 동통과 식욕결핍을 호소하는 15세 남아에서 위 내시경과 조직 생검으로 진단된 원발성 위 림프종 1례를 경험하였기에 문헌 고찰과 함께 보고하는 바이다. Primary gastric lymphoma is relatively uncommon, accounting for 3% to 8% of all malignancies arising in the stomach. The most common symptom is abdominal pain, closely followed by weight loss, anorexia, weakness due to anemia, nausea, and vomiting. The diagnosis of gastric lymphoma usually requires a biopsy at the time of gastroscopy or laparotomy. Microscopically, the vast majority of gastric lymphoid tumors are non-Hodgkin's lymphomas of B cell origin. Survival rates for all types of gastric lymphoma generally exceed those for adenocarcinoma and other malignancies of the stomach. We experienced one case of primary gastric lymphoma in puberty with a brief review of the literature.

The Gallery of Casa del Agua in Jeju Island was demolished by Jeju local government on March 6 in the last year. In the meanwhile, a lot of people including the architectural field had denied the demolition. Regardless of sustained efforts in order that the building could be preserved as a work, Jeju government ended up with demolishing the gallery. The Gallery of Casa del Agua was a temporary building constructed as a model house of Casa del Agua. As the remaining period of the temporary building had passed, it was on the verge of demolition by Jeju government. Casa del Agua is 'dwelling of water' in Korean, and the building was the last posthumous work of Mexican architect Ricardo Legorreta. Knowing from the expression of 'dwelling of water', this house is a dwelling work of him. Through this work, his architecture languages that he had pursued contained in dwelling could be looked into. This study examined the background and course of demolition of the Gallery of Casa del Agua, 'dwelling of water' and arranged problems in the course of demolition. Then, the fact that the Gallery of Casa del Agua as an architecture work of Ricardo Legorreta included his architecture languageswas analyzed. For this, his universalarchitecture languages were examined and how the architecture languages were applied to the Gallery of Casa del Agua was analyzed. As a result, it could be known that languages of composition and languages of emotion consistently shown in his works were represented in the Gallery of Casa del Agua.

The exploitation of technologies based on electro spinning have been limited due to poor understanding of the process and consequent limitation in process control, productivity and reproducibility. To control the effect of the environmental parameter, which is one of important electro spinning parameters, the vacuum process was introduced because the magnitude of electric field in vacuum is not limited by the low dielectric breakdown strength of air. For this study, PCL dissolved in a mixture of N,N-dimethylformamide (DMF) and methylene chloride (MC) was electrospun as a form of nonwoven mats consisting of nano-sized fibers under vacuum and they have been analyzed using SEM and DSC. The PCL nonwoven mats via electrospinning under vacuum showed the characteristic spinning behavior observed at atmospheric pressure. In addition, results obtained from tensile test showed that PCL nonwoven mats via electro­spinning under vacuum have better mechanical properties than those prepared at atmospheric pressure.

Numerical Analysis for exchanging seawater experiment is carried out in Do-Jang fish port. The change of tidal velocity and water level is derived by the two-dimensional nonlinear shallow-water numerical model. To calculate exchange rate of seawater with the change of tidal velocity and water level, a two-dimensional numerical model is employed which governing equations are Fokker-Plank equations. The calculated exchange rates of each time are described in tables and figures.

외국인 거주자의 시공간적 분포패턴 및 결정요인: 서울시 생활인구 데이터 분석

김형준,원미리,이정민,채호동,박인권,Kim, Hyungjoon,Won, Milee,Yi, Jungmin,Chae, Hodong,Park, In Kwon 한국토지주택공사 토지주택연구원 2021 LHI journal of land, housing, and urban affairs Vol.12 No.1

국내 외국인 인구가 지속적으로 증가함에 따라 사회적·경제적·정치적 측면에 있어 그 영향력이 더욱 커지고 있다. 본 연구는 서울의 지역적 특성이 외국인 인구의 시공간적 분포에 어떤 영향을 미치는지 살펴보는 것에 그 목적이 있다. 먼저 외국인 인구의 시공간적 분포패턴을 파악하기 위해 k-means 군집분석을 통해 주간유출·야간유입(ODIN), 주간유입·야간유출(IDON), 비식별패턴(IP) 3개의 유형으로 분류하였다. 이후 주중 및 주말 다항 로지스틱 회귀모형을 설정하였고, 외국인의 시공간적 패턴에 영향을 미치는 지역적 특성을 파악하였다. 지역적 특성 변수는 인구, 산업구조, 도시계획, 용도지역, 주거, 체류자격 관련 변수를 선정하였다. 분석결과, 주중 모형의 경우, ODIN 및 IDON유형 모두 도심지역 여부가 가장 큰 영향을 보임을 확인하였다. 주거지역 면적비율 또는 방문취업(H-2)비자 비율이 높을수록 IDON유형으로 분류될 확률이 낮은 반면 ODIN유형으로 분류될 확률이 높은 것으로 나타났으며, 이를 통해 외국인 인구의 직주분리현상을 발견할 수 있었다. 본 연구결과는 향후 외국인 인구 관련 행정수요파악 및 정책수립 등에 기초자료로 활용될 수 있을 것이다. This paper examines the relationship between spatial-temporal distribution patterns of foreign populations and regional characteristics of Seoul Metropolitan area. Using the estimated de facto population data, first, Cluster analyses provide three groups of characteristics of Seoul : an outflow of daytime population and inflow of night-time population pattern (ODIN); an inflow of daytime population and outflow of night-time population (IDON); and indistinguishable pattern (IP). Second, Multinomial logistic regression models predict the probability of selecting ODIN and IDON patterns using some local characteristic variables such as population, visa status, type of residential area, the structure of industry, urban planning and zoning. The findings indicate that the location within the central business district is the most significant determinant for both ODIN and IDON patterns during weekdays. We also found that the higher proportion of residential area and the proportion of working visa status increase the probability of selecting ODIN patterns whereas it decreases the probability of selecting IDON patterns. This study suggests that the foreign population, similar to local residents, experiences spatial mismatch between jobs and housing. Given the steady increase of foreign population in South Korea, the foreign population implies further pressure on social and economic aspects of Seoul. This study suggests a forward plan for migration policy for foreign population.
