Conversations and Medical News Frames on Twitter: Infodemiological Study on COVID-19 in South Korea

Background SARS-CoV-2 (severe acute respiratory coronavirus 2) was spreading rapidly in South Korea at the end of February 2020 following its initial outbreak in China, making Korea the new center of global attention. The role of social media amid the current coronavirus disease (COVID-19) pandemic has often been criticized, but little systematic research has been conducted on this issue. Social media functions as a convenient source of information in pandemic situations. Objective Few infodemiology studies have applied network analysis in conjunction with content analysis. This study investigates information transmission networks and news-sharing behaviors regarding COVID-19 on Twitter in Korea. The real time aggregation of social media data can serve as a starting point for designing strategic messages for health campaigns and establishing an effective communication system during this outbreak. Methods Korean COVID-19-related Twitter data were collected on February 29, 2020. Our final sample comprised of 43,832 users and 78,233 relationships on Twitter. We generated four networks in terms of key issues regarding COVID-19 in Korea. This study comparatively investigates how COVID-19-related issues have circulated on Twitter through network analysis. Next, we classified top news channels shared via tweets. Lastly, we conducted a content analysis of news frames used in the top-shared sources. Results The network analysis suggests that the spread of information was faster in the Coronavirus network than in the other networks (Corona19, Shincheon, and Daegu). People who used the word “Coronavirus” communicated more frequently with each other. The spread of information was faster, and the diameter value was lower than for those who used other terms. Many of the news items highlighted the positive roles being played by individuals and groups, directing readers’ attention to the crisis. Ethical issues such as deviant behavior among the population and an entertainment frame highlighting celebrity donations also emerged often. There was a significant difference in the use of nonportal (n=14) and portal news (n=26) sites between the four network types. The news frames used in the top sources were similar across the networks (P=.89, 95% CI 0.004-0.006). Tweets containing medically framed news articles (mean 7.571, SD 1.988) were found to be more popular than tweets that included news articles adopting nonmedical frames (mean 5.060, SD 2.904; N=40, P=.03, 95% CI 0.169-4.852). Conclusions Most of the popular news on Twitter had nonmedical frames. Nevertheless, the spillover effect of the news articles that delivered medical information about COVID-19 was greater than that of news with nonmedical frames. Social media network analytics cannot replace the work of public health officials; however, monitoring public conversations and media news that propagates rapidly can assist public health professionals in their complex and fast-paced decision-making processes.
SeqL: Secure Scan-Locking for IP Protection

Existing logic-locking attacks are known to successfully decrypt functionally correct key of a locked combinational circuit. It is possible to extend these attacks to real-world Silicon-based Intellectual Properties (IPs, which are sequential circuits) through scan-chains by selectively initializing the combinational logic and analyzing the responses. In this paper, we propose SeqL, which achieves functional isolation and locks selective flip-flop functional-input/scan-output pairs, thus rendering the decrypted key functionally incorrect. We conduct a formal study of the scan-locking problem and demonstrate automating our proposed defense on any given IP. We show that SeqL hides functionally correct keys from the attacker, thereby increasing the likelihood of the decrypted key being functionally incorrect. When tested on pipelined combinational benchmarks (ISCAS, MCNC), sequential benchmarks (ITC) and a fully-fledged RISC-V CPU, SeqL gave 100% resilience to a broad range of state-of-the-art attacks including SAT [1], Double-DIP [2], HackTest [3], SMT [4], FALL [5], Shift-and-Leak [6] and Multi-cycle attacks [7].
Evaluation of growth and bioaccumulation of cobalt in different tissues of common carp, Cyprinus carpio [Actinopterygii: Cypriniformes: Cyprinidae], fed cobalt-supplemented diets

Two separate trials made with fingerlings of common carp, Cyprinus carpio : a growth trial made in outdoor cement tanks for 60 days and a digestibility trial made in 15-L glass aquaria in the laboratory for 7 days. Four experimental diets (average crude protein 30.94%) supplemented by four different levels of Co (0.00%, 0.05%, 0.10%, and 1.0%) were formulated and tested in these two trials. Growth was evaluated from gain in weight, specific growth rate, feed conversion ratio, and deposition of protein and lipid in the body of the fish. Apparent protein digestibility (APD) of the diets was evaluated from the proportion of chromium (Cr) and protein in the diet and faeces. Water qualities were checked every week and levels of Co in liver, kidney, gill, gut, and caudal trunk of the fish were determined by atomic absorption spectrophotometer at the end of 60 days in the growth trial. the control diet. Although conversion rate, weight gain and SGR were significantly higher in 0.05% CSD as compared with control diet (0.00% CSD), there was no significant difference in apparent protein digestibility (APD), apparent net protein utilization (ANPU), and deposition of crude protein in the body between fish fed control and 0.05% CSD. Fish fed 1.0% CSD showed significantly higher level of Co in different tissues as compared with other diet groups. Conclusion. It is concluded from the present study that dietary supplement of Co (0.1% to 1.0%) serves as a growth promoter for common carp. Increased growth with no additional tissue burden of Co is achieved at 0.1% dietary Co, while a higher level of supplement (1.0%) may result in increased deposition of Co in different tissues.
Testing Models of Relationship Participation, Task Complexity, System Complexity and Satisfaction with Performance

The transformation of the Ministry of Defense's budget policy, the Indonesian National Armed Forces Headquarters and three other departments (Army Headquarters, Navy Headquarters and Air Force Headquarters) from the money follow function to money follow approach requires the implementation and development of holistic financial planning, budgeting and management information systems. thematic and integrative. The pattern of relationships between variables concerning human resources in organizations, such as user participation, user satisfaction, user perceptions of task complexity, perceptions of system complexity and perceptions of system performance determine the effectiveness and efficiency of information systems. This study aims to find out what the overall level of compatibility of the model explains the direct and indirect relationship between participation, task complexity, system complexity, satisfaction with performance. Using a single cross-sectional survey design, data collection through face-to-face interviews with 209 information system users with a questionnaire as the main data collection tool and data analysis applying the structural equation model (Structural Equation Model) with the help of LISREL 8.5 software, this study concluded that there were compatibility of the whole model, measurement model and structural model hypothesized by research with data obtained from research (survey).
METHOD OF CONSTRUCTING EXPLANATIONS FOR RECOMMENDER SYSTEMS BASED ON THE TEMPORAL DYNAMICS OF USER PREFERENCES

The problem of constructing explanations for recommendations in situations of cold start and shilling attacks is considered. The first situation is characterized by incomplete information about the user's preferences, and the second is characterized by a distortion of the ratings of items in the recommendation system. A method for constructing explanations for the recommended list of subjects is proposed. The method uses weighted temporal dependencies to form explanations. Each such dependence reflects a change in sales of goods for two non-contiguous time intervals. These intervals are set according to a given level of detail of time, for example, day, week, month. The input is presented by a sales journal with time stamps. The method includes the steps of forming temporal rules, calculating the weights of the rules, building explanations. The weights of the rules reflect the degree of change in sales for a pair of intervals. The result of the method is a recommendation in the form of a numerical estimate of the change in user preferences with respect to the subject in the recommendation. The proposed method allows to increase sales efficiency due to the active selection of items by the user based on the explanations received

Effect of different male-to-female ratios and testosterone administration upon the male sexual behavior and the out-of-season reproductive response of anestrous goats

The possible effect of testosterone administration and the male-to-female ratio regarding the male sexual behavior during the resting season and the out-of-season reproductive performance of anestrous goats exposed to the male effect under subtropical conditions (26◦ N) was evaluated. In the experiment-1 two treatments were considered (1) Testosterone-treated bucks (TTB; n = 4; 25 mg, i.m., testosterone, every 3-days × 3-week), and (2) Non-testosterone treated bucks (NTTB; n = 4; i.m. saline every 3-days × 3week). Thereafter, both experimental groups were exposed to adult goats over two days (1 h × 2days) and two sexual behavior tests were performed: appetitive sexual behavior (ASB) and consummatory sexual behavior (CSB). In the experiment-2, multiparous lactating and anoestrous crossbred goats (n = 60) were randomly assigned to one of four treatments with different male-to-female ratios (MFR): (1) High MFR goats [HMFR; n = 20, 1:10 ratio], (2) Low MFR [LMFR; n = 10, 1:5 ratio] each group exposed to two NTTB, (3) High MFR goats [HMFR + T; n = 20, 1:10 ratio], and (4) Low MFR [LMFR + T; n = 10, 1:5 ratio] each group exposed to two TTB. While the TTB displayed higher ASB (p < 0.01; 91.9% vs 8.1 %), the NTTB did not express neither CSB (p > 0.05; 100% vs 0%) nor sexual behavior irrespectively of the male-to-female load. The HMFR + T depicted a higher ASB (p < 0.01; 65% vs 35%) than the LMFR + T, without differences in CSB between HMFR + T and LMFR + T. Also, TTB induced estrus response (86.6%) and pregnancy rate (83.3%) while NTTB did not. Neither estrus response (85 vs 90%) nor pregnancy rate (85 vs 80%) differed between the HMFR + T and LMFR + T groups. Exposing of anestrous goats to testosterone-treated bucks, irrespective of mating load, was able to successfully invoke neurophysiological pathways to activate ovarian function and to promote a uterine milieu prone to the establishment of pregnancy during the anoestrus season. © 2015 Elsevier B.V.

FOOD PRODUCTION TECHNOLOGY EFFECTS OF IN-PACKAGE PASTEURIZATION ON PREVENTING SPOILAGE IN EMULSION VACUUM PACKAGED SAUSAGES DURING REFRIGERATED STORAGE

Lactic acid bacteria (LAB) dominate the spoilage populations of vacuum-packaged emulsion-type sausages and other processed meats stored at refrigeration temperatures. An experimental investigation was carried out to evaluate the effectiveness of two in-package pasteurization treatments to prevent microbial spoilage in emulsion vacuum packaged sausages during refrigerated storage. D-values at 60 and 68°C for two isolated dominant LAB (Lactobacillus sakei and Lactobacillus plantarum) were determined in vitro and thermal treatments aimed to achieve a 4 log reduction in LAB. Sixty three sausage packs were divided into 3 groups: untreated packs (Control), treated at 60°C for 120 s (PAST 1) and treated at 68°C for 12 s (PAST 2). Microbial composition, pH values and sensorial changes were monitored in two-week intervals. In-package pasteurization resulted in an immediate 3.5–4.2 log CFU/g reduction in the population of LAB in PAST 1 and PAST 2 and remained at an acceptable level to the end of the experiment. On the contrary, during 84 days of cold storage, the LAB count increased significantly in the control samples and reached 9 log CFU/g. The control samples were also considered as unacceptable spoiled products after 28 days by sensorial aspects. All the pasteurized treatments also resulted resulted a significant (p < 0.05) reduction of psychrotrophic and the total mesophilic bacteria compared to the control ones. The data obtained showed that in both pasteurized groups none of the sensorial parameters were rated higher than the consumer-rejection threshold within 84 days of the study. No significant (p > 0.05) differences were observed in the number of spores, yeasts and molds between the pasteurized and control samples. It has been concluded that in-package pasteurization is an effective method without undesirable effects to prevent the spoilage caused by LAB growth and extend the emulsion vacuum packaged sausages shelf life to more than 3 months.
Habitat use of Intertidal Eastern Oyster (Crassostrea virginica) Reefs by Nekton in South Carolina Estuaries

ABSTRACT The majority of recent studies investigating the habitat value of intertidal oyster reefs have compared the nektonic assemblages on natural oyster reefs, salt marshes, mud bottom, and subtidal oyster shell habitats using methods that involve some degree of habitat disturbance. The current study used a novel, non-destructive sampling approach involving the deployment of a drop net around study plots to compare the nektonic assemblages associated with intertidal oyster reefs (natural and enhanced) with those of neighboring soft sediment habitats at 3 sites in South Carolina. At each site, the nektonic organisms collected on a reef plot were compared with those collected on an adjacent control plot lacking a structurally complex habitat. Nekton abundance was significantly higher on the reef plot compared with the control plot at all 3 sites. Nekton abundance also varied among seasons, with the greatest numbers occurring during summer compared with spring and fall. Notably, grass shrimp (Palaemonetes spp.) were especially dominant on reef plots. A total of 60 taxa were identified, 57 of which were identified to species level. Reef plots exhibited significantly greater taxon richness than control plots. The number of taxa present also accumulated over time at a higher rate on the reef plots than on the control plots at 2 of the 3 sites. Among the 60 taxa collected, 36 were found on both the reef and control plots, whereas 14 taxa were unique to the reef plots. For data pooled across all sites and seasons, 33 taxa were more numerous on reef plots than control plots, 3 taxa occurred in equal numbers, and 24 taxa were more numerous on control plots. For taxa collected on more than 1 occasion, paired t-tests performed with Bonferroni-adjusted significance thresholds revealed that Alpheus heterochaelis and Palaemonetes spp. were significantly more abundant on the reef plots than on the control plots, whereas unadjusted analyses revealed the same pattern for Gobiosoma bosc, Menidia menidia, and Fundulus heteroclitus. In contrast, no taxa were significantly more abundant on the control plots at either significance threshold. Although nekton abundance was generally higher on the reef plots, measures of diversity were significantly higher on the control plots, regardless of season, site, or date. Greater abundance of a limited number of species on the reef plots accounted for lower evenness and therefore lower diversity measures for this treatment. Overall, community structure was driven more by site than by treatment, whereas the seasonal occurrences of certain species on the reef plots highlighted the importance of oyster reefs as essential fish habitat for the critical life stages of finfish species with complex life histories.
DEVELOPMENT AND VALIDATION OF A SCIENCE EDUCATION PACKAGE FOR EMPOWERING THE RURAL WOMAN WITH ENTREPRENEURIAL SKILLS FOR PERSONAL AND NATIONAL DEVELOPMENT

Every nation of the world is endowed with one resource or the other, in terms of minerals, water and human resource. The contributions of human resources to national growth and development depends on the training received and this helps to put other resources into effective use. In Nigeria past neglect on woman education has led to several rural women not educated, women are said to be at a disadvantaged position. Access to education, school provisions and relations of contents to gainful employment are some of the factors militating against women empowerment (Okeke,2006; Ezeudo, 2008). Education to the Nigeria government is the key to national development; it Boosts National economy and self reliance. Actualization of these leads to transformed education but it is far from this because many of the citizens are illiterate especially women. Science Education is expected to produce informed citizens of good quality equipped with appropriate knowledge and high technical skills groomed with practical dexterity to use their hands, heads and hearts for self-reliance and National development. Science has been acknowledged all over the world as a tool for national development and it is a necessity in all areas of human endeavor. Current development in science has greatly affected the lives of every human being such that if the knowledge of science is ignored, it means that man lives in an empty and meaningless world therefore the rural woman should not be left out of science Knowledge. Science also has contributed to human lives in areas such as health, nutrition, agriculture, transportation, material and energy production and industrial development. It is in view of this that the authors chose to develop and validate a science education package for the rural woman to acquire science knowledge and skills for entrepreneurship to better their lives and for national development. This paper examined entrepreneur skills in science that will be taught to rural women as a skill acquisition that are suitable for entrepreneurial Endeavors. It also looked at how the rural woman will have personal and national development through such skills, that is a process of providing individuals with the ability to recognize commercial opportunities, self-esteem, knowledge and skills to act on them.
Soybean Yield Reductions Caused by Defoliation during Mid to Late Seed Filling

Little is known about soybean [Glycine max (L.) Merr. ] yield response to defoliation during the last half of the seed-filling period (R6.3 to R7) and how it is affected by source/sink ratio. Because defoliating insect pests in the southeastern USA frequently attack soybean during this period, greater knowledge of yield responses to defoliation at this time would aid in making management decisions. Therefore, the objectives of this field study were to (i) determine yield losses to total defoliation near the temporal midprint (R6.3) and three-quarter print (R6.6) of the seed-filling period; (ii) determine if alterations in source/sink ratio affect this response and (iii) determine yield component mechanisms responsible for the yield reduction. «Centennial» soybean was planted in 1991 and 1992 near St. Gabriel, LA. Treatments were no defoliation (control), 100% defoliation at R6.3, and 100% defoliation at R6.6 arranged as split plots within high, normal, and low source/sink ratios during seed filling (main plots). Defoliation at R6.3 resulted in 40% yield reduction, whereas defoliation at R6.6 caused a 20% yield loss. Lower yield resulted form reduced seed size. Source/sink ratio did not affect this resprose. Smaller seed size in both defoliation treatments resulted partly form reduced seed-filling rate (28% less than control). Shorter effective filling period also contributed to smaller seed size, but this effect was influenced by treatments and years. In conclusion, 100% defoliation during R6.3 to R6.6 must be avoided to maintain optimum yield
Prenatal Anxiety among Pregnant Women Visiting in Antenatal Care Outpatient Department at Paropakar Maternity and Women's Hospital

Background: Prenatal anxiety is a normal and natural experience. It can affect a person’s feelings, thoughts, behavior, and physical well-being. The majority of maternal deaths are due to hemorrhage, infection, unsafe abortion, and eclampsia which is due to knowledge deficit and anxiety. The objective of this study is to assess the level of prenatal anxiety among pregnant women visiting in ANC OPD at Paropakar Maternity and Women’s Hospital (PMWH). Materials & Methods: A descriptive cross-sectional study included 337 respondents from Antenatal Care (ANC) outpatient department of Paropakar Maternity and Women’s Hospital, Thapathali, Kathmandu. Ethical clearance was obtained from Nepal Health Research Council and Institutional Review Committee (IRC) of Paropakar Maternity and Women’s Hospital, Kathmandu. Prenatal Anxiety Screening Scale was used for data collection. Period of data collection was October 1st to November 1st 2017. Interview technique was used and data was analyzed by using descriptive and inferential statistics. Findings; the finding revealed that mean age of the respondents were 24.68± 2.99 years. 39.5 % respondents were primi gravida. Less than fifty (40.9%) of respondents had minimal anxiety, 42.1% had mild to moderate level anxiety and least (16.9%) of the respondents had severe anxiety. The study showed that there is association between anxiety and gravida (p<0.05) of the respondents. Conclusion: Based on the findings present study revealed that less than fifty percentages of respondents had minimal and mild to moderate level of anxiety and least of the respondent had severe level of anxiety. There was significant association between level of anxiety and gravida of the respondents. Furthermore, it is concluded that prenatal anxiety has relation with the gravid of pregnant women.
Macroeconomic indicators within economic transition in ECC countries

The present article discusses some of crucial macroeconomic indicators within economic transition in Central and Eastern European countries (CEE), which started the process of transition in 1989, with the fall of the Berlin Wall. We compare five CEE countries (Slovenia, Slovakia, Czech Republic, Hungary and Poland), in order to analyse their economic transition’s outcomes regarding seven crucial macroeconomic indicators: real gross domestic product (GDP), gross domestic product growth, gross domestic product per capita (GDP p.c.), foreign direct investments (FDI), unemployment rate, inflation rate and global competitiveness index (GCI). The aim of the article is to analyse (un)successfulness of economic transition, based on two contradictory approaches these countries have chosen to undergone, i.e. shock therapy and gradualism, while also its possible causal link with transition approach and transition outcomes.
