Although it is well known that cancer patients suffer from malnutrition, there are few published studies on malnutrition in outpatients receiving chemotherapy in Korea. This study aimed to evaluate nutritional risk in oncology outpatients receiving chemotherapy and to show the baseline data to set up nutritional management programs for cancer patients. This is a retrospective observational analysis on 1,962 patients referred for nutritional education before or during chemotherapy at Seoul National University Hospital Cancer Center from January 2006 to May 2007. According to a malnutrition screening tool, the proportion of patients having malnutrition risk was 23.0%. In the case of upper gastrointestinal cancer, more than 50% of patients were assessed as being at the risk of malnutrition. They showed more than 7% weight loss compared to their usual body weight and poor oral intake; energy intake was less than 100% of Basal Energy Expenditure (BEE) and protein intake was less than or equal to 0.77 g/㎏/d. However, only 6.3% of breast cancer patients had risk of malnutrition and their oral intake was better; energy intake was 121% of BEE, and protein intake was 0.90 g/㎏/d. Outpatients receiving chemotherapy had different nutritional risk depending on their cancer site. Nutritional management program should be conducted differently, depending on the cancer site and upper gastrointestinal cancer patients at high risk of malnutrition should basically have nutritional assessment and intervention.

NMR Solvent Peak Suppression by Piecewise Polynomial Truncated Singular Value Decomposition Methods

Kim, Dae-Sung,Lee, Hye-Kyoung,Won, Young-Do,Kim, Dai-Gyoung,Lee, Young-Woo,Won, Ho-Shik Korean Chemical Society 2003 Bulletin of the Korean Chemical Society Vol.24 No.7

A new modified singular value decomposition method, piecewise polynomial truncated SVD (PPTSVD), which was originally developed to identify discontinuity of the earth's radial density function, has been used for large solvent peak suppression and noise elimination in nuclear magnetic resonance (NMR) signal processing. PPTSVD consists of two algorithms of truncated SVD (TSVD) and L₁ problems. In TSVD, some unwanted large solvent peaks and noise are suppressed with a certain soft threshold value, whereas signal and noise in raw data are resolved and eliminated in L₁ problems. These two algorithms were systematically programmed to produce high quality of NMR spectra, including a better solvent peak suppression with good spectral line shapes and better noise suppression with a higher signal to noise ratio value up to 27% spectral enhancement, which is applicable to multidimensional NMR data processing.

Objective: To assess the safety and efficacy of balloon dilatation under dual guidance using fluoroscopy and bronchoscopy for treating bronchial stenosis following lung transplantation (LT), and to elucidate the factors associated with patency after the procedure. Materials and Methods: From September, 2012, to April, 2021, 50 patients (mean age ± standard deviation, 54.4 ± 12.2 years) with bronchial stenosis among 361 recipients of LT were retrospectively analyzed. The safety of balloon dilatation was assessed by evaluating procedure-related complications. Efficacy was assessed by evaluating the technical success, primary patency, and secondary patency. Primary and secondary cumulative patency rates were calculated using the Kaplan-Meier method. The factors associated with patency after the procedure were evaluated using multivariable Cox hazard proportional regression analysis. Results: In total, 65 bronchi were treated with balloon dilatation in 50 patients. The total number of treatment sessions was 277 and the technical success rate was 99.3% (275/277 sessions). No major procedure-related complications were noted. During the mean follow-up period of 34.6 ± 30.8 months, primary patency was achieved in 12 of 65 bronchi (18.5%). However, the patency rate improved to 76.9% (50 of 65 bronchi) after repeated balloon dilatation (secondary patency). The 6-month, 1-year, 3-year, and 5-year secondary patency rates were 95.4%, 90.8%, 83.1%, and 78.5%, respectively. The presence of clinical symptoms was a significant prognostic factor associated with reduced primary patency (adjusted hazard ratio [HR], 0.465; 95% confidence interval [CI], 0.220–0.987). Early-stage treatment ≤ 6 months (adjusted HR, 3.588; 95% CI, 1.093– 11.780) and prolonged balloon dilatation > 5 min (adjusted HR, 3.285; 95% CI, 1.018–10.598) were associated with significantly higher secondary patency. Conclusion: Repeated balloon dilatation was determined to be safe and effective for treating bronchial stenosis following LT. Early-stage treatment and prolonged balloon dilatation could significantly promote long-term patency.

Kim, Won Gyoung,Choi, Injoo,Yoon, Jihyun The Korean Nutrition Society 2016 Nutrition Research and Practice Vol.10 No.6

BACKGROUND/OBJECTIVES: The nutritional quality of lunches is an important factor related to workers' health. This study examined the nutritional quality of Korean workers' lunches with a focus on comparing institutional and commercial lunches. SUBJECTS/METHODS: The data from a 1-day, 24-hour dietary recall from the $5^{th}$ Korea National Health and Nutrition Examination Survey (2010-2012) were analyzed. A total of 2,192 subjects aged 19 to 64 years, who had consumed lunches served by institutional or commercial food service vendors, were included for analysis. The nutritional quality of the lunches of the institutional lunch group (n=626) and the commercial lunch group (n=1,566) was compared in terms of the number of servings, food groups, nutrient intake, Nutrient Adequacy Ratio (NAR), and Mean Adequacy Ratio (MAR). RESULTS: The NAR and MAR were significantly higher in the institutional lunches than in the commercial lunches, but more than half of workers in both groups obtained over 65% of their energy from carbohydrate. The average sodium intake from the lunches exceeded the daily intake goal (2,000 mg) in both groups. More than half of workers in both groups presented less than one-third of their respective recommended daily intake of riboflavin and calcium. With the exception of riboflavin, the nutrient intake from lunches accounted for more than 35% of the daily nutrient intake. CONCLUSIONS: The overall nutritional quality of institutional lunches was higher than that of commercial lunches. However, institutional lunches had room for improvement in terms of nutritional quality.

<P><B>Abstract</B></P> <P>The use of chemoresistive gas sensors based on metal oxides has expanded to various fields such as medical diagnosis and air quality systems as well as gas leakage detectors with the development of the Internet of Things. Accordingly, sensitivity, selectivity, power consumption, and reproducibility become important factors in the development of gas sensors. Herein, we developed a facile method to fabricate a gas sensor based on porous Au-incorporated tungsten trioxide (WO<SUB>3</SUB>) thin films for highly sensitive and selective NO<SUB>2</SUB> sensing. The mixed solution of ammonium tetrathiotungstate [(NH<SUB>4</SUB>)<SUB>2</SUB>WS<SUB>4</SUB>] and gold chloride (AuCl<SUB>3</SUB>) was transformed to Au-incorporated WO<SUB>3</SUB> thin films through the spin-coating and annealing process. The gas sensors based on the Au-incorporated WO<SUB>3</SUB> thin films exhibited improved sensitivity, selectivity, and response time upon exposure to NO<SUB>2</SUB> with a significantly low theoretical detection limit of 28 ppt at 150 ℃ compared to gas sensors based on the pristine WO<SUB>3</SUB> thin film. The high sensing properties are attributed to the porous structure and catalytic effects of Au nanoparticles. In addition to these remarkable NO<SUB>2</SUB> sensing properties, the facile and cost-effective fabrication process enlarges the potential of the Au-incorporated WO<SUB>3</SUB> thin films for practical and commercial gas sensing applications.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Au-incorporated WO<SUB>3</SUB> thin films are synthesized by the facile method using solution process and annealing. </LI> <LI> Sensors based on the Au-incorporated WO<SUB>3</SUB> thin films exhibit high sensitivity and good selectivity for NO<SUB>2</SUB> sensing. </LI> <LI> The enhanced sensing properties are attributed to the porous structure and the catalytic effect of the Au nanoparticles. </LI> </UL> </P>

우리나라 다문화청소년의 학업성취도에 영향을 미치는 요인 탐색

김원경(Won Gyoung Kim),최필선(Pilsun Choi) 한국다문화교육학회 2023 다문화교육연구 Vol.16 No.4

한국 사회에 다문화가정이 안정적으로 정착하는 것은 사회의 다양성과 포용성을 증대시키고 사회적 통합을 강화하는 데 중요한 의미를 지닌다. 다문화가정이 겪는 어려움 중 자녀교육이 가장 큰 부분을 차지하고 있고, 정부 역시 그동안 이주 초기 적응지원에 집중하던 것에서 이제는 그 자녀들의 학업적, 사회적 성취를 돕는 데 중점을 두는 방식으로 정책변화를 꾀하고 있다. 본 연구는 다문화청소년패널조사 1차년도에서 9차년도까지의 데이터를 활용하여 다층성장모형을 통해 어떤 요인들이 다문화청소년들의 학업성취도에 영향을 미치는지 분석한다. 학령기 다문화자녀가 계속 늘어나고 이들의 교육문제가 다문화가정 지원정책의 핵심으로 대두되고 있는 상황에서 다문화청소년들의 학업성취도에 어떤 요인들이 중요한 의미를 갖는지를 살펴보는 것은 다문화가정과 청소년들의 현 상황을 이해하고, 그들에게 필요한 올바른 지원 대책을 도출하는 데 중요한 의미를 지닐 것이다. 추정 결과, 성취동기, 삶의 만족도, 부모 학력, 가족의 지지, 부모의 관리감독, 학교 밖 도움을 주는 어른의 존재 등이 학업성적을 높이는 요인으로 작용하는 반면, 예상과 달리 경제적 요인이나 집단괴롭힘 경험 등은 유의한 영향을 미치지 않는 것으로 나타났다. The successful acculturation of families from diverse cultural backgrounds holds significant importance in enhancing diversity, inclusivity, and social integration in Korea. Multicultural families encounter numerous challenges with a substantial focus placed on assisting their children in achieving success in school. In response to this challenge, the Korean government has shifted its policy emphasis from initial immigrant adaptation support to prioritizing the academic and social achievements of these children. This study draws upon ten years of collected data from the Multicultural Adolescents Panel Survey to examine the evolving academic achievement of multicultural youth over time. We employ a multilevel growth model to analyze the factors that influence the academic achievement of multicultural youth. Given the continuous increase in the number of school-aged multicultural children and the growing significance of policies supporting the education of multicultural children, it is crucial to comprehend the factors affecting the academic achievement of multicultural youth, assess their current situation, and derive appropriate support measures. Our estimated results indicate that several factors, including motivation, life satisfaction, parental education, family support, parental supervision, and the presence of adult support outside of school, positively influence academic performance. On the other hand, economic factors and experiences of bullying do not have a significant impact.
