Analysis of design preference to Korean and Chinese casual style were made targeting Chinese female students in Korea. The following conclusion was derived from the result of final 300-copy survey data, using SPSS 18.0 program. The data were analyzed by frequency, t-test, chi-squre independence test, ANOVA and Scheffe test. Firstly, when comparing change of design preference before the stay in Korea with after the stay in Korea, the biggest change in their preference was character casual style, while the least change was easy casual wear. In terms of duration of stay in Korea, the biggest change was from the group of over 3 years, and in the order of the group of 1-3years, and then lastly less than 1 year, which suggests that the longer the duration of stay, the bigger the change. When comparing preferred clothing color before the stay in Korea with after the stay in Korea, both before and after the stay in Korea had the highest preference for achromatic colors. The frequency of change was mostly from achromatic color to other colors. In the preferred clothing pattern, 'plain' was their favorite one before the stay in Korea, while it turned to 'nature pattern' after the stay in Korea, followed by 'plain' one. In the textiles, the most preferred one was 'cotton', before and after the stay in Korea. However, their preference for cotton was lower after their stay in Korea than before the stay in Korea, and instead there was more preference for 'silk', 'synthetic fiber', and 'other' sources.

Background: Postoperative air leaks after pulmonary resection prolong the duration of chest drainage and the length of hospital stay. One of the many treatment options is bedside pleurodesis using various agents. This study evaluated the feasibility of an early intervention to stop postoperative air leaks with either autologous blood or a 50% glucose solution. Methods: We retrospectively reviewed 323 patients who underwent bedside pleurodesis between January 2017 and March 2022. Sixty-four patients received autologous blood patch pleurodesis, and 36 were treated with a 50% glucose solution after pulmonary resection. The primary endpoints were the total postoperative tube indwelling time, post-pleurodesis tube indwelling time, and hospital stay. A propensity score-matched analysis was performed. Results: In the autologous blood patch pleurodesis and 50% glucose solution groups, the mean initiation timing of postoperative pleurodesis were 2.06±1.62 and 3.28±1.56 days, the mean duration of the tube indwelling time after surgery was 6.58±3.02 and 6.42±4.92 days, and the mean duration of the tube indwelling time after pleurodesis, it was 4.53±3.10 and 3.11±4.80 days, respectively. In addition, the total length of hospital stay was 9.11±5.42 and 7.83±4.75 days in the autologous blood patch pleurodesis and 50% glucose solution groups, respectively. Conclusion: Early postoperative air leak cessation with autologous blood patch pleurodesis or 50% glucose solution pleurodesis is a feasible procedure with acceptable outcomes that effectively shortens the hospital stay.

Background: Promoting patients' safe return home at discharge and reducing length of stay in hospital is key for Restorative Rehabilitation Institution (RMI). Objects: This study was designed to identify the factors influencing the return to home and length of stay among various factors. Methods: A total of 120 stroke patients (76 males and 44 females) who were hospitalized in an adult inpatient unit of a RMI for more than 2 months were retrospectively analyzed for this study (multivariate logistic regression analyses, p < 0.001). As predictor variables for assessing the return to home and length of stay, demographic data (sex, age, duration between onset and admission, length of stay, caregiver after discharge, occupation after discharge, reason for discharge, and household type after discharge) were collected. Additionally, following measurements were selectively collected from patient's medical records: scores of Mini-Mental State Examination Korean version (K-MMSE), modified Barthel Index Korean version (K-MBI), Berg Balance Scale and Functional Ambulation Category were obtained at admission and discharge. Results: The K-MMSE at admission and K-MBI at discharge were found to be the predictors of return to home. Additionally, K-MBI at admission influenced the length of stay. Conclusion: This study suggests cognitive functioning at admission and the level of activities of daily living at discharge predicted the return to home and length of stay.

Object: We evaluated the efficacy of chest physical therapy in pediatric patients with pneumonia. Method: Retrospective study was performed in 89 pneumonia patients admitted to pediatric unit. The subjects were divided into two groups: control group; treatment group. Control group included 42 patients who didn't receive chest physical therapy. Treatment group included 47 patients who received chest physical therapy. The chest physcial therapy employed were postural drainage, chest percussion, deep breathing training and enhancement of coughings. The efficacy was evaluated by x-ray outcome before discharge. Results: There were no significant difference in age, sex, type of pneumonia, and symptom duration between two groups. However the duration of fever after admission, duration of antibiotic use and hospital stay were longer in treatment group. In treatment group, longer the day to initiate chest physical therapy, longer the hospital stay. The final outcome was not different between groups. Conclusion: The results suggest that the referred patients for chest physical therapy tends to be of severe cases. Nevertheless, the result that the outcome was not different in two groups means that the chest physical therapy could be used as a effective treatment method in pediatric patient with pneumonia.

사장교 케이블은 초기 큰 인장력으로 축강성이 매우 크지만, 횡방향 휨강성은 약하다. 풍하중이나 교통하중은 케이블을 심각하게 진동시켜 사장교의 사용성에 부정적 영향을 끼친다. 그러므로 장대교량에 감쇠장치를 설치하는 진동 저감 계획이 절실히 요구된다. 마찰댐퍼는 교통하중이나 풍하중과 같은 동적하중이 작용하는 케이블 진동에서 진폭과 지속시간을 대폭 감소시킬 수 있는 효과적인 장치임을 알 수 있다. 케이블 진동은 댐퍼제작방법과 설치위치 및 형상에 따라 효율이 달라질 수 있다. 그럼에도 불구하고 본 실험연구의 마찰댐퍼 설치전 후 제진성능효과 분석결과는 향후 사장케이블의 진동을 저감시키는 기본 자료로 활용할 수 있다.

본 연구는 한국 TV 드라마에 따른 한국 내 중국 유학생들의 프로그램 몰입을 결정하는 요인이 무엇인가를 분석하였다. 주요 연구 결과는 다음과 같다. 첫째, 한국 드라마와 오락 프로그램에 대한 중국 유학생들의 몰입도를 살펴보면, 드라마보다 오락 프로그램 몰입도가 보다 높게 나타났다. 드라마가 이야기 구조와 스타 등장에 의존하는 콘텐츠라면 오락 프로그램은 보다 역동적이며 즐거움의 정도가 높기 때문에 중국 유학생들의 몰입도를 높이는 요인으로 판단된다. 둘째, 드라마와 오락 프로그램 몰입도를 성별, 한국어 능력 수준별, 한국 체류 기간별로 구분해서 평균값 차이를 살펴본 결과, 성별로는 드라마와 오락 프로그램 모두 통계적으로 유의미한 차이가 나타났다. 반면, 한국어 능력 수준이나 오락 프로그램에 대해 한국 체류 기간별 차이는 의미 있는 결과가 나타나지 않았다. 그러나 드라마 몰입도는 한국 체류 기간이 오래될수록 몰입도가 증가하는 결과를 살펴볼 수 있다. 셋째, 드라마와 오락 프로그램 몰입도 결정 요인을 살펴본 결과, 드라마 몰입도의 경우에는 프로그램 독특성, 한국 체류 기간, 드라마 장르 선호도 요인이 통계적으로 유의미한 것으로 나타났다. 다음으로 오락 프로그램 몰입도의 경우에는 프로그램 독특성, 스타 출연, 오락 장르 선호도 요인이 통계적으로 유의미한 것으로 나타났다.

Objective : This study aimed to investigate the rates, types, and risk factors of surgical site infection (SSI) following intracranial neurosurgical procedures evaluated by a Korean SSI surveillance system. Methods : This was a prospective observational study of patients who underwent neurosurgical procedures at 29 hospitals in South Korea from January 2017 to June 2017. The procedures included craniectomy, craniotomy, cranioplasty, burr hole, and ventriculoperitoneal shunt. Univariate and multivariate logistic regression analyses were performed. Results : Of the 1576 cases included, 30 showed infection, for an overall SSI rate of 1.9%. Organ/space infection was the most common, found in 21 out of the 30 cases (70%). Staphylococcus aureus was the most common (41%) of all bacteria, and Serratia marcescens (12%) was the most common among gram-negative bacteria. In univariate analyses, the p-values for age, preoperative hospital stay duration, and over T-hour were <0.2. In a multivariate analysis of these variables, only preoperative hospital stay was significantly associated with the incidence of SSI (p<0.001), whereas age and over T-hour showed a tendency to increase the risk of SSI (p=0.09 and 0.06). Conclusion : Surveillance systems play important roles in the accurate analysis of SSI. The incidence of SSI after neurosurgical procedures assessed by a national surveillance system was 1.9%. Future studies will provide clinically useful results for SSI when data are accumulated.

Objective : This 2009-2011 nation-wide study of adult Koreans was aimed to provide characteristics, medical utilization states, and survival rates for newly diagnosed patients with primary nonmalignant and malignant spine tumors. Methods : Data for patients with primary spine tumors were selected from the Korean Health Insurance Review and Assessment Service database. The data included their age, sex, health insurance type, co-morbidities, medical cost, and hospital stay duration. Hospital stay duration and medical costs per person occurring in one calendar year were used. In addition, survival rates of patients with primary malignant spine tumors were evaluated. Results : The incidence rate of a primary spine tumor increased with age, and the year of diagnosis ($p{\leq}0.0001$). Average annual medical costs ranged from 1627 USD (pelvis & sacrum & coccyx tumors) to 6601 USD (spinal cord tumor) for primary nonmalignant spine tumor and from 12137 USD (spinal meningomas) to 20825 USD (pelvis & sacrum & coccyx tumors) for a primary malignant spine tumor. Overall survival rates for those with a primary malignant spine tumor were 87.0%, 75.3%, and 70.6% at 3, 12, and 24 months, respectively. The Cox regression model results showed that male sex, medicare insurance were significantly positive factors affecting survival after a diagnosis of primary malignant spine tumor. Conclusion : Our study provides a detailed view of the characteristics, medical utilization states, and survival rates of patients newly diagnosed with primary spine tumors in Korea.

Objective : Postoperative delirium is a common complication in the elderly after surgery but few papers have reported after spinal surgery. We analyzed various risk factors for postoperative delirium after spine surgery. Methods : Between May 2012 and September 2013, 70 patients over 60 years of age were examined. The patients were divided into two groups : Group A with delirium and Group B without delirium. Cognitive function was examined with the Mini-Mental State Examination-Korea (MMSE-K), Clinical Dementia Rating (CDR) and Global Deterioration Scale (GDS). Information was also obtained on the patients' education level, underlying diseases, duration of hospital stay and laboratory findings. Intraoperative assessment included Bispectral index (BIS), type of surgery or anesthesia, blood pressure, fluid balance, estimated blood loss and duration of surgery. Results : Postoperative delirium developed in 17 patients. The preoperative scores for the MMSE, CDR, and GDS in Group A were $19.1{\pm}5.4$, $0.9{\pm}0.6$, and $3.3{\pm}1.1$. These were significantly lower than those of Group B ($25.6{\pm}3.4$, $0.5{\pm}0.2$, and $2.1{\pm}0.7$) (p<0.05). BIS was lower in Group A ($30.2{\pm}6.8$ compared to $35.4{\pm}5.6$ in group B) (p<0.05). The number of BIS <40 were $5.1{\pm}3.1$ times in Group A, $2.5{\pm}2.2$ times in Group B (p<0.01). In addition, longer operation time and longer hospital stay were risk factors. Conclusion : Precise analysis of risk factors for postoperative delirium seems to be more important in spinal surgery because the surgery is not usually expected to have an effect on brain function. Although no risk factors specific to spinal surgery were identified, the BIS may represent a valuable new intraoperative predictor of the risk of delirium.
