본 연구는 한국복지패널 7차년도를 이용하여 공공임대주택거주가 우울에 미치는 영향을 분석하였다. 공공임대주택거주가 개인의 선택에 의해 이루어지는 과정에서 발생가능한 선택 편의를 줄이기 위해 PSM(propensity score matching)을 활용하였으며, 최종적으로는 우울에 영향을 미치는 다른 변수들을 통제하기 위해 PSM의 매칭결과와 회귀분석을 결합하였다. 분석결과 단순비교(independent t-test)에서는 통계적으로 유의미하였던 공공임대주택거주자와 일반주택거주자간의 우울의 차이가 PSM매칭과 회귀분석을 결합하였을 때는 유의미성이 사라졌다. 이는 공공임대주택거주자의 높은 우울정도는 공공임대주택거주의 독립적인 효과라기보다는 공공임대주택거주자가 가지고 있는 본래적인 인구학적인 속성 혹은 소득에 기인하였을 가능성을 보여준다. 본 연구는 공공임대주택거주가 개인에게 부정적인 영향을 미치지 않음을 확인하였다는 점에서 공공임대주택 공급에 대한 정책적 근거를 제공하고 있다. 동시에 긍정적인 영향도 확인할 수 없었다는 점에서, 저소득층에 한정하지 않은, 국민 대다수를 위한 임대주택정책을 제안하였다.

Purpose: There is no consensus on the optimal method for intracorporeal esophagojejunostomy (EJ) in laparoscopic total gastrectomy (LTG). This study aims to compare 2 established methods of EJ anastomosis in LTG. Materials and Methods: A total of 314 patients diagnosed with gastric cancer that underwent LTG in the period from January 2013 to October 2016 were enrolled in the study. In 254 patients, the circular stapler with purse-string "Lap-Jack" method was used, and in the other 60 patients the linear stapling method was used for EJ anastomosis. After propensity score matching, 58 were matched 1:1, and retrospective data for patient characteristics, surgical outcome, and post-operative complications was reviewed. Results: The 2 groups showed no significant difference in age, body mass index, or other clinicopathological characteristics. After propensity score matching analysis, the linear group had shorter operating time than the circular group ($200.3{\pm}62.0$ vs. $244.0{\pm}65.5$, $P{\leq}0.001$). Early postoperative complications in the circular and linear groups occurred in 12 (20.7%) and 15 (25.9%, P=0.660) patients, respectively. EJ leakage occurred in 3 (5.2%) patients from each group, with 1 patient from each group needing intervention of Clavien-Dindo grade III or more. Late complications were observed in 3 (5.1%) patients from the linear group only, including 1 EJ anastomosis stricture, but there was no statistical significance. Conclusions: Both circular and linear stapling techniques are feasible and safe in performing intracorporeal EJ anastomosis during LTG. The linear group had shorter operative time, but there was no difference in anastomosis complications.

Background: Coronary artery bypass grafting (CABG) is being offered increasingly frequently to octogenarians. However, old age is known to be an independent risk factor in CABG. The aim of this study was to compare the outcomes of off-pump coronary artery bypass (OPCAB) between octogenarians and septuagenarians. Methods: We retrospectively reviewed the data of 1,289 consecutive patients aged ${\geq}70years$ who underwent OPCAB at a single institution between 2001 and 2016. We compared the outcomes of 115 octogenarians and 1,174 septuagenarians. Using propensity score matching, based on preoperative clinical characteristics, 114 octogenarians were matched with 338 septuagenarians. Results: Propensity score analysis revealed that the incidence of acute kidney injury (14.9% vs. 7.9%, p=0.028) and respiratory complications (8.8% vs. 4.2%, p=0.040) was significantly higher in octogenarians. The early mortality rate (2.6% vs. 1.0%, p=0.240) and 1-year survival rate (89.5% vs. 94.4%, p=0.097) were not statistically significant between the groups. However, the 5-year survival rate (67.3% vs. 79.9%, p<0.001) was significantly lower in octogenarians. Previous myocardial infarction and a left ventricular ejection fraction ${\leq}35%$ were associated with a poor 1-year survival rate. Conclusion: Early and 1-year outcomes of OPCAB in octogenarians were tolerable when compared with those in septuagenarians. OPCAB could be a suitable option for octogenarians.

농업 기업가의 과학 기술적 경향은 새로운 기회를 식별하고 탐구하기 위해 필요해지고 있다. 최근 연구에 따르면 신기술의 채택은 기업가적 지향(EO)의 광범위한 접근법과 일치한다. 농업의 타당성이 증가하고 있다고 해도, 기업가적 연구는 대체로 이 도전적인 분야를 간과해 왔다. 게다가, 문헌에는 경험적 연구가 상대적으로 부족하고 여전히 연구되어야 하는 부분이며 잠재력이 있다고 논하고 있다. EO의 문헌에서 비롯된 이 연구는 농업 분야인 HEO(Humanine Entrepreneural Orientation)의 접근을 제안한다. 이 논문은 HEO의 다양한 치수가 농가의 신기술 채택 성향에 미치는 영향을 검증하기 위한 경험적 분석을 제안한다. 모든 결과는 기업, 연구 시스템 및 공공 정책에 대한 몇 가지 시사점을 강조한다. 농업이 매우 특이한 분야이고 제조업과 상당히 다르더라도 농민도 기업인으로 볼 수 있으며 기업가정신을 따를 수 있다고 본다. 따라서, 경험적 연구의 상대적 부족인 농업 EO에 대한 문헌을 본 연구를 통해 풍부하게 할 수 있다고 본다.

Objectives : The purpose of this study is to analyze the effects of treatment between Western medicine and Korean medicine on Allergic rhinitis patients using national population-based claim data from the Health Insurance Review and Assessment Service. Methods : The subjects of the study were 30,024 patients in the Korean medicine group and 30,024 in the Western medicine group who were diagnosed with Allergic rhinitis from September 1, 2018 to December 31, 2018. Propensity score analysis was used for matching age, sex, etc. at a ratio of 1:1. Cox regression and subgroup analysis were used to estimate the adjusted hazard ratio of recurrence, Asthma, and Atopic dermatitis in Korean medicine group and Western medicine group. In addition, the total treatment period, total treatment cost, and average cost per day of visit were compared and analyzed. Results : Compared to Korean medicine, Western medicine had a significantly higher risk of recurrence at 1.701 times, Asthma occurrence risk at 1.609 times and Atopic dermatitis occurrence risk at 1.098 times. Compared to Western medicine, the total treatment period of Korean medicine was 14.27 days longer, the total treatment cost was 53,591 won more, and the average cost per day was 7,539 won more. Conclusions : This study is a retrospective cohort study using the propensity score matching in Korea to compare the outcomes of Allergic rhinitis between Western medicine and Korean medicine. Further research is needed by considering patients characteristics, and linking with additional data.

Purpose: This study was conducted to evaluate the prevalence and lifestyle habits of cardiovascular disease (CVD) according to the type of disability in Korean adults compared to adults without disability. Methods: This study was secondary data analysis using the National Health check-up database from 2010 to 2013. Among the total 395,627 adults aged 30~80, the physically disabled (n=21,614) and the mentally disabled (n=1,448) who met the diagnosis criteria were extracted and compared with non-disabled (n=372,565) through 1:2 propensity score matching for nine characteristics. Results: Prior to matching, the prevalence of CVD was 34.4% in individuals without disabilities, accounting for 53.8% in those with physical disabilities and 22.4% in those with mental disabilities, showing significant differences between groups (p<.001). After matching, compared to the individuals without disability, those with physically disabled had significantly higher prevalence of CVD and the average number of CVD (p<.001). The prevalence of hypertension, diabetes, and vascular disease was significantly higher in the physically disabled (p<.05). Drinking was significantly higher in the non-disabled than in the physically and mentally disabled, and smoking was more in the non-disabled than in the mentally disabled. Physical activity was found to be significantly less in both the physically and mentally disabled than in the non-disabled (p<.01). Conclusion: It is necessary to confirm the differences in the prevalence of CVD risk factors and lifestyle according to the type of disability, suggesting the development and verification of health promotion programs including physical activity for CVD prevention in the disabled with CVD risk factors.

Objectives: The study aimed to analyze the effects of household financial difficulties caused by COVID-19 (2019 coronavirus disease) on suicidal tendencies of adolescents. Methods: We selected 54,948 middle and high school students who were surveyed based on the Korean Youth Risk Behavior Web-based Survey 2020. To analyze the data, we used the STATA 16.0 program to conduct propensity score matching (PSM). Results: After controlling for selection effects by using PSM, the household financial difficulties caused by COVID-19 maintained a significant predictive effect on increasing suicidal ideation, suicide attempts, and decreasing tendency in hospital-treated after suicide attempts. However, depressive symptoms and suicide plan did not show a significant correlation with household financial difficulties associated with COVID-19. Conclusions: It was found that the rate of suicidal ideation and suicide attempts among adolescents who experienced a household financial difficulties due to COVID-19. Therefore, It can provide empirical evidence for estimating the impact of COVID-19 on adolescent suicide rates.

계속거주의향에 관한 기존 연구에서는 지역소멸 위기를 더 많이 느끼는 주민일수록 지역을 떠나겠다는 의향을 밝힐 확률이 높아지는 경향이 있음을 밝히고 있다. 하지만 연령이 증가함에 따른 이동성 제약을 고려해 본다면, 지역쇠퇴와 이주의향의 관계성은 연령에 따라 다르게 나타날 수 있다. 본 연구는 지역소멸 위기감이 계속거주의향에 미치는 영향력이 연령에 따라 다르게 나타나는지 실증적으로 검증하고자 했다. <한겨레21>의 「인구감소 지역 주민들의 생활 실태와 인식 조사」자료를 사용해 분석한 결과, 계속거주의향에 대한 지역소멸 위기감의 영향력은 나이가 많을수록 작아지는 것으로 나타났다. 본 연구의 결과는 인구감소지역에 대한 대응책을 수립함에 있어서 연령에 따른 차이를 고려할 필요가 있음을 보여준다.

Objective : Hypernatremia is a common complication encountered during the treatment of neurocritically ill patients. However, it is unclear whether clinical outcomes correlate with the severity of hypernatremia in such patients. Therefore, we investigated the impact of hypernatremia on mortality of these patients, depending on the degree of hypernatremia. Methods : Among neurosurgical patients admitted to the intensive care unit (ICU) in a tertiary hospital from January 2013 to December 2019, patients who were hospitalized in the ICU for more than 5 days and whose serum sodium levels were obtained during ICU admission were included. Hypernatremia was defined as the highest serum sodium level exceeding 150 mEq/L observed. We classified the patients into four subgroups according to the severity of hypernatremia and performed propensity score matching analysis. Results : Among 1146 patients, 353 patients (30.8%) showed hypernatremia. Based on propensity score matching, 290 pairs were included in the analysis. The hypernatremia group had higher rates of in-hospital mortality and 28-day mortality in both overall and matched population (both p<0.001 and p=0.001, respectively). In multivariable analysis of propensity score-matched population, moderate and severe hypernatremia were significantly associated with in-hospital mortality (adjusted odds ratio [OR], 4.58; 95% confidence interval [CI], 2.15-9.75 and adjusted OR, 6.93; 95% CI, 3.46-13.90, respectively) and 28-day mortality (adjusted OR, 3.51; 95% CI, 1.54-7.98 and adjusted OR, 10.60; 95% CI, 5.10-21.90, respectively) compared with the absence of hypernatremia. However, clinical outcomes, including in-hospital mortality and 28-day mortality, were not significantly different between the group without hypernatremia and the group with mild hypernatremia (p=0.720 and p=0.690, respectively). The mortality rates of patients with moderate and severe hypernatremia were significantly higher in both overall and matched population. Interestingly, the mild hypernatremia group of matched population showed the best survival rate. Conclusion : Moderate and severe hypernatremia were associated with poor clinical outcomes in neurocritically ill patients. However, the prognosis of patients with mild hypernatremia was similar with that of patients without hypernatremia. Therefore, mild hypernatremia may be allowed during treatment of intracranial hypertension using hyperosmolar therapy.
