Objectives: Thiamine is thought to modify sleeping patterns, while alcohol use diminishes internal thiamine levels. We investigated the association between thiamine intake and sleep duration and explored possible heterogeneity in the effect according to alcohol use. Methods: In total, 15 384 participants aged 19-64 were obtained from the Korea National Health and Nutrition Examination Survey 2012-2016. Nutrient intake, including thiamine, was measured using a food frequency questionnaire. Sleep duration was measured by a self-reported questionnaire. The highest thiamine intake quartile was set as the reference group. Participants were divided into 3 groups, with 7-8 hours of daily sleep as a reference group and those who slept more or less than that as "oversleeping" and "insufficient sleeping," respectively. Multivariate logistic regression was used, adjusting for socioeconomic, medical, and nutritional factors. Additionally, participants were stratified according to high-risk alcohol use defined by the World Health Organization standards on alcohol use. Results: Low thiamine intake was associated with oversleeping (Q3: odds ratio [OR], 1.06; 95% confidence interval [CI], 0.86 to 1.32; Q2: OR, 1.24; 95% CI, 0.99 to 1.55; Q1: OR, 1.49; 95% CI, 1.16 to 1.91) and showed a significant trend for higher ORs at lower intake levels (p-trend<0.001). The effect was stronger in the high-risk alcohol use group (Q1: OR, 1.78; 95% CI, 1.28 to 2.49). Conclusions: Low thiamine intake was associated with oversleeping, and alcohol use intensified that association. These results were found in a context where overt clinical symptoms due to thiamine deficiency are considered rare. More awareness of the potential relationship of thiamine intake with oversleeping and its related risks should be considered.

Objectives: The objective of this study was to examine the relations between total vegetable and Kimchi intakes and the risk of metabolic syndrome (Mets) in Korean adults. Methods: This study used dietary intake and health data of 6668 subjects aged 20 years and over from the 2010-2011 Korea National Health and Nutrition Examination Survey (KNHANES). Daily intakes of total vegetables and Kimchi were assessed by 24-hour recall data. The odds ratio of Mets risk according to daily intake of vegetables and Kimchi was analyzed, respectively. Results: The highest consumption of total vegetables was associated with a lower risk of abdominal obesity (multivariable adjusted OR=0.56, 95% CI: 0.33, 0.93) in men and lower risk of Mets (multivariable adjusted OR=0.67, 95% CI: 0.47, 0.94) in women. Kimchi consumption was not related to the risk of Mets in both men and in women. However, a higher intake of Kimchi was associated with an increased risk of elevated blood pressure (Q1 vs Q5, multivariable adjusted OR=1.34, 95% CI: 0.95, 1.90, P for trend= 0.0261) in women. Conclusions: A higher intake of vegetables was associated with decreased risk of abdominal obesity and Mets in both men and women, respectively. A higher consumption of Kimchi was not related to the risk of Mets in both in men and in women. However, a higher intake of Kimchi was associated with an increased risk of elevated blood pressure in women.

Objectives: This study was conducted to examine the relationship between white rice and Kimchi intakes and the risk of metabolic syndrome (Mets) in Korean adults. Methods: Dietary intake and health data of 8289 subjects aged 19 years and over from the 2013-2015 Korea National Health and Nutrition Examination Survey (KNHANES) were used. Daily total intake of white rice and Kimchi was assessed by 24-hour recall data. Multivariate logistic regression analysis was used to estimate the risk of Mets according to the daily intake of white rice and Kimchi. Results: The highest intake of white rice and Kimchi was associated with a higher risk of metabolic syndrome (Q1 vs Q5, multivariable adjusted OR=1.45, 95% CI: 1.03-2.03) in women. In addition, a significantly increased risk of elevated blood pressure (multivariable adjusted P for trend 0.0459) was associated with a higher intake of white rice and Kimchi in women. There was no significant trend in the risk of metabolic syndrome according to the intake of white rice and Kimchi in men. Conclusions: A higher intake of white rice and Kimchi was only associated with an increased risk of metabolic syndrome in women indicating it is necessary to consume more various food groups beside white rice and Kimchi, especially in women.

우리의 일상생활에 큰 변화를 가져온 코비드-19는 대학 교육에도 역시 큰 변화를 가져왔다. 전통적인 대면 수업방식에서 비대면 방식으로 변경되어 수업이 이루어지면서 교수자와 학생 모두 적응에 애를 먹는 모습을 보였고, 비대면 수업으로 인한 학력 격차의 발생 등의 문제 역시 제기되었다. 이에 본 연구는 코비드-19로 인한 대학의 비대면 수업에 대해 학생들이 어떠한 태도를 보이는지 알아보고자 하였다. 이에 본 연구는 Q 방법론을 적용하여 대학생들이 비대면 수업에 대해 가지고 있는 주관적 인식의 유형을 파악하고 이를 통해 향후 비대면 수업방식의 개발과 개선에 있어 참고할 점을 제안하고자 하였다. 30명의 P 표본과 34개의 Q 표본을 이용하여 분석한 결과 5개의 유형이 발견되었다. 첫째, 학습의 효율성 중시형, 둘째, 수업의 참여와 소통 중시형, 셋째, 비대면 수업의 적극적 수용과 활용형, 넷째, 원격 시스템과 장비 작동 오류로 인한 불만형, 다섯째, 상황에 따른 수동적 대응형이다. 본 연구의 결과를 바탕으로 살펴보았을 때 각 유형의 특성을 고려한 효과적인 비대면 수업을 위한 교육 방법의 개발이 필요할 것으로 보이며, 비대면 수업, 특히 녹화 강의가 갖는 학습의 효율성 측면에서의 장점은 분명한 것으로 보인다. 따라서 대면 수업이 대학에서 전면적으로 이루어지더라도 수업에서 동영상 녹화 강의를 보완적으로 제공하는 것이 학생들의 학습에 큰 도움이 될 것으로 여겨진다.

Background: Local anesthetic infiltration at the site of a surgical wound is commonly used to control postoperative pain. In this study, we examined the effectiveness of continuous local infiltration at an abdominal surgical site in patients undergoing anterior lumbar interbody fusion (ALIF) surgery. Methods: Sixty-one patients who underwent ALIF surgery were enrolled. For thirtyone of them, a continuous local anesthetics infiltration system was used at the abdominal site. We collected data regarding the patients' sleep quality; satisfaction with pain control after surgery; abilities to perform physical tasks and the additional application of opioids in the postoperative 48 hours. Results: The On-Q system group showed reduced visual analogue scale scores for pain at the surgical site during rest and movement at 0, 12, 24, and 48 hours; and more was satisfied with pain control management at the first postoperative day (7.0 ± 1.2 vs. 6.0 ± 1.4; P = 0.003) and week (8.1 ± 1.6 vs. 7.0 ± 1.8; P = 0.010) than the control group. The number of additional patient-controlled analgesia (PCA) bolus and pethidine injections was lower in the On-Q group (PCA: 3.67 ± 1.35 vs. 4.60 ± 1.88; P = 0.049 and pethidine: 2.09 ± 1.07 vs. 2.73 ± 1.38; P = 0.032). Patients who used the On-Q system performed more diverse activity and achieved earlier ambulation than those in the control group. Conclusions: Continuous wound infiltration with ropivacaine using an On-Q system may be effective for controlling postoperative pain after ALIF surgery.

The effects of daily feeding frequency (Exp I), water temperature (Exp II), and stocking density (Exp III) on the growth of river puffer, Takifugu obscurus, juvenile fish of 10 and 40 g in body weight were examined to develop effective techniques to produce river puffer in a non-exchange water system. In Exp I, fish were fed commercial floating feed with 45 % protein one to five times per day to apparent satiation each by hand daily for 8 weeks at $25^{\circ}C$. In both the 10- and 40-g size groups, the final body weight, daily feed consumption, and weight gain of fish fed one meal per day were significantly lower than those of fish fed five meals per day (P < 0.05). However, there were no significant differences in the final body weight, daily feed consumption, and weight gain among fish fed two, three, and five meals per day. Feed efficiency showed decreasing tendency with increasing size of fish. In Exp II, fish of 10 and 40 g in initial body weight were reared with the commercial feed at $15-30^{\circ}C$ for 8 weeks. The weight gain of fish increased with raising water temperature up to $25^{\circ}C$ and decreased drastically at $30^{\circ}C$ for both sizes. The Q10 of specific growth rate was decreased with raising water temperature from 5.04 (temperature interval, $15-20^{\circ}C$) to 0.66 ($25-30^{\circ}C$) for the 10-g fish and from 4.98 to 0.31 for the 40-g fish. In Exp III, the effect of stocking density on growth was examined with fish of 10 and 40 g in initial body weight. The final body weight for initial stocking densities of 4, 8, and $12kg/m^3$ was significantly higher than that of $20kg/m^3$ for the 10-g fish, and the final stocking density reached 10.1, 19.2, 28.7, and $39.9kg/m^3$, respectively. For the 40-g fish, the final body weight for initial stocking densities of 3 and $6kg/m^3$ was significantly higher than that of 9 and $15kg/m^3$ and the final stocking density reached 7.38, 13.5, 17.1, and $27.5kg/m^3$, respectively (P < 0.05). In both groups, weight gain tended to decrease with increasing stocking density; however, survival showed no significant difference.

Recently, the COVID 19 pandemic has affected on our daily lives and society in many ways. Specifically, it has brought rapid changes in the working environment from office working to smart telecommuting. In addition, cloud computing technology and services not only provided ubiquitous access, but also led to a sharing of information, internal-external communication channels, telework, and innovative smart work for the business process. As a result, smart work services based on social cloud networking have spread to the public sector. However, existing academic research examining smart work merely remains to focus on the theoretical conceptualization or to deal with merely several examples of private views. Best practices of smart work services based on cloud computing technology in the public field rarely exists. Moreover, many studies have been differently measured the values of smart work for private and public sectors depending on organizational singularities. Therefore, the study aims to define new theoretical implications and to explore future business strategies and policy directions based on a technical working group's personal psychological subjectivity. The research applied Q methodology, and selected five public organizations in Korea, that they have adopted or currently plan to adopt some part of smart work services.

In this study, we evaluated uncertainties in baseflow separation filter methods focusing on changes in recession constant (𝛼) values, which include Lynie & Holick (LH) algorithm, Chapman algorithm, Eckhardt filter, and EWMA filter. Here, we analyzed daily streamflow data at 14 stations in the Urmia Lake basin, Iran, from 2015 to 2019. The 𝛼 values were computed using three different approaches from calculating the slope of a recession curve by averaging the flow over all seasons, a correlation method, and a mean value of the ratio of Q_t+1 to Q_t. In addition to the 𝛼 values, the BFImax (maximum value of the baseflow index (BFI)) was determined for the Eckhardt filter through the backward filter method. As results, it indicates that the estimated baseflow is dependent upon the selection of filter methods, their parameters, and catchment characteristics at different stations. In particular, the EWMA filter showed the least changes in estimating the baseflow value by changing the 𝛼 value, and the Eckhardt filter and LH algorithm showed the highest sensitivity to this parameter at different stations.
