Objective We aimed to identify the expectations and preferences for medication and medical decision-making in patients with major psychiatric disorders.Methods A survey was conducted among patients with major psychiatric disorders who visited psychiatric outpatient clinics at 15 hospitals between 2016 and 2018 in Korea. The survey consisted of 12 questions about demographic variables and opinions on their expectations for medication, important medical decision-makers, and preferred drug type. The most preferred value in each category in the total population was identified, and differences in the preference ratio of each item among the disease groups were compared.Results A total of 707 participants were surveyed. In the total population, patients reported high efficacy (44.01%±21.44%) as the main wish for medication, themselves (37.39%±22.57%) and a doctor (35.27%±22.88%) as the main decision makers, and tablet/capsule (36.16%±30.69%) as the preferred type of drug. In the depressive disorders group, the preference ratio of high efficacy was significantly lower, and the preference ratio of a small amount was significantly higher than that of the psychotic disorder and bipolar disorder groups. The preference ratio of a doctor as an important decision maker in the bipolar disorder group was higher compared to the other groups.Conclusion This study revealed the preference for medications and showed differences among patients with psychiatric disorders. Providing personalized medicine that considers a patient’s preference for the drug may contribute to the improvement of drug compliance and outcomes.

For the industrial pollution and energy crisis of auto industry, New vehicle system needs to improve fuel efficiency in idling mode. A solution to the Idle Stop and Go (ISG) system is being considered by the auto industry. This paper introduces development of HIL simulation environment, which simulates the behavior of the 12V ISG system. In case of actual vehicle test, it involves a number of constraints of experimental variable control and arrangement, cost for the development. Therefore, in this paper, test-bench based on HIL is developed to build reliable verification environment for improvement research related to ISG system. The key component such as starter-motor and alternator are selected real parts. And the dynamic simulation model of vehicle for HIL simulation is bulilt by using Matlab Simulink.

Purpose The present study was to evaluate the outcomes of Denali filter retrieval. Materials and Methods We retrospectively reviewed 143 patients who received Denali filter insertion from September 2015 to April 2020. Ninety-seven patients who required removal of the filters were include in this study. Filters were retrieved with either standard or advanced techniques. Venography before and after retrieval was obtained to evaluate technical success, complications and duration of filter insertion. Results All 97 filters were retrieved successfully without complications. Ninety-two (94.8%) were retrieved with standard technique and 5 filters (5.2%) required the advanced technique. There were two cases with a filter angle greater than 15 degrees. Inferior vena cava penetration was shown in 17 patients (17.5%) on venography but was not associated with contrast media extravasation after filter removal. Conclusion The Denali filter showed a high rate of successful retrieval without complications. This study adds value to previous studies and trials showing that the Denali filter is a reliable and safe filter that can potentially improve retrieval rates, with increasing use of this device.

Salt content of school meals and comparison of perception related to sodium intake in elementary, middle, and high schools

Sohyun Ahn,Seoyun Park,Jin Nam Kim,Sung Nim Han,Soo Bin Jeong,Hye-Kyeong Kim 한국영양학회 2013 Nutrition Research and Practice Vol.7 No.1

Excessive sodium intake leading to hypertension, stroke, and stomach cancer is mainly caused by excess use of salt in cooking. This study was performed to estimate the salt content in school meals and to compare differences in perceptions related to sodium intake between students and staffs working for school meal service. We collected 382 dishes for food from 24 schools (9 elementary, 7 middle, 8 high schools) in Gyeonggi-do and salt content was calculated from salinity and weight of individual food. The average salt content from elementary, middle, and high school meals were 2.44 g, 3.96 g, and 5.87 g, respectively. The amount of salt provided from the school lunch alone was over 80% of the recommended daily salt intake by WHO. Noodles, stews, sauces, and soups were major sources of salt intake at dish group level, while the most salty dishes were sauces, kimchies, and stir-fried foods. Dietary knowledge and attitude related to sodium intake and consumption frequency of the salty dishes were surveyed with questionnaire in 798 students and 256 staffs working for school meal service. Compared with the staffs, the students perceived school meals salty and the proportions of students who thought school meals were salty increased with going up from elementary to high schools (P < 0.001). Among the students, middle and high school students showed significant propensity for the preference to one-dish meal, processed foods, eating much broth and dipping sauce or seasoning compared with the elementary students, although they had higher nutrition knowledge scores. These results proposed that monitoring salt content of school meals and consideration on the contents and education methods in school are needed to lower sodium intake.

본 연구는 2019년 1월 1일∼2021년 12월 31일 가상자산의 거래에 영향을 미치는 요인을 분석하였다. 분석을 위해 비정형데이터인 뉴스 및 기사에서 가상자산과 관련된 자료를 수집하고, KNU 사전을 바탕으로 해당 자료에 나타난 감성을 추정하였다. 그리고 자기회귀모형과 패널회귀모형을 적용하여 가상자산 거래에 영향을 주는 요인을 분석하였다. 본 연구의 주요 발견은 다음과 같다. 첫째, 가격 상승기가 시작되는 시점에 뉴스 및 기사의 빈도수가 증가하는 경향이 있다. 둘째, 본 연구의 분석 기간의 가상자산에 대한 감성은 대체로 긍정 감성으로 나타난다. 하지만, 상승기 및 하락기의 긍정 및 부정 감성에 명확한 차이는 확인할 수 없다. 셋째, 변동성의 비대칭성과 레버리지 현상이 나타난다. 넷째, 부정 감성과 뉴스 빈도수는 가격변화에 시차를 두고 영향력이 있지만, 거래량의 변화에는 즉각적인 영향력 및 그 영향력의 지속성을 발견하였다. 반면, 투자 심리를 자극하는 요인인 부정 감성과 뉴스빈도가 가격과 거래량 변화에 미치는 영향은 통계적으로 유의미하나, 방향성은 일관되지 않는다. 이와 같은 투자자의 감성이 가상자산의 거래에 미치는 영향력 및 통계적으로 유의미한 비일관적인 영향력의 발견은 본 연구의 차별적인 결과이다. 한편, 가상자산의 가격 및 거래량 변동성은 가상자산의 거래 현황 및 특성이 반영된, 시장의 이상 반응(anomaly)이라 판단한다. 따라서, 가상자산의 거래에 있어서 투자자의 주의 및 금융 당국의 적절한 역할이 요구된다. We analyzed the trading of virtual assets that ranged from January 1, 2019 to December 31, 2021 using atypical data. To analyze, data related to virtual assets from news and articles, which are atypical, were collected and the sentiment in the data was estimated based on the KNU dictionary. Our findings are as follows. First, the frequency of news and articles tends to increase at the beginning of the price increase period. Second, the sentiment on virtual assets during the analysis period of this study is generally positive. Third, our findings show the asymmetry of volatility and leverage effect in virtual assets trading. Fourth, negative sentiment and news frequencies have an influence over time on price changes, but those have an immediate influence and persistence of this influence on changes in trading volume. While, the impact of sentiment in trading is not consistent, it is statistically significant. Consequently this study considers the volatility of virtual assets as an anomaly in the virtual assets market. Thus, our study recommends an investor's attention and an appropriate role of financial authorities, in trading virtual assets.
