Epidemiological Characteristics

Abstract International flights have accelerated the global spread of Coronavirus Disease 2019 (COVID-19). Determination of the optimal quarantine period for international travelers is crucial to prevent the local spread caused by imported COVID-19 cases. We performed a retrospective epidemiological study using 491 imported COVID-19 cases in Chengdu, China, to describe the characteristic of the cases and estimate the time from arrival to confirmation for international travelers using nonparametric survival methods. Among the 491 imported COVID-19 cases, 194 (39.5%) were asymptomatic infections. The mean age was 35.6 years (SD=12.1 years) and 83.3% were men. The majority (74.1%) were screened positive for SARS-CoV-2, conducted by Chengdu Customs District, the People’s Republic of China. Asymptomatic cases were younger than presymptomatic or symptomatic cases (P<0.01). The daily number of imported COVID-19 cases displayed jagged changes. 95% of COVID-19 cases were confirmed by PT-PCR within 14 days (95% CI: 13-15) after arriving in Chengdu. A 14-day quarantine measure can ensure non-infection among international travelers with a 95% probability. Policymakers may consider an extension of the quarantine period to minimize the negative consequences of the COVID-19 confinement and prevent the international spread of COVID-19. Nevertheless, the government should consider the balance between COVID-19 and socioeconomic development, which may cause more serious social and health crises.

Abstract Background: Crystal (methamphetamine) is a strong stimulant of addictive substances that affects the central nervous system. The consumption of this substance is increasing among teenagers and adult young people in the country. In this matter, one of the practical and important ways to its control is to identify the factors leading to its first use. Thus this paper, explores the factors related to the first crystal use in Golestan province, Iran.Methods: In a qualitative study, 19 crystal users were recruited in the study conducted in Golestan province by snowball sampling from DIC (Drop-In Center) in addiction treatment centers. The interviews were mostly carried out individually with the participants; only one interview was conducted in an addiction treatment camp in the form of a group-focused discussion. Data analysis was implemented through content analysis in MAXQDA 10 software.Results: The mean age of the participants was 35.05± 6.06 years with a range of 23-46 years. Meanwhile, the mean of crystal use period was 7.42 (SD:3.61) and a range of 1-14 years. Based on the obtained data, the reasons for first crystal use could be categorized in six; 1: "crystal use to other drugs rehabilitation"; 2: "Lack of awareness of the addictive nature of crystal"; 3: “stimulating curiosity in public with crystal-use friends” , 4: affordable and convenient use”, 5: "anti-sleeping effects and increasing work efficiency", and 6: "therapeutic and other misconceptions”".Conclusions: The results indicated that crystal is mostly abused to opium rehabilitation. The lack of awareness and misconceptions about this substance can lead people to crystal use. Therefore, designing public health interventions to increase awareness about negative consequences of crystal use is fundamental to prevent people from abusing it. We suggest designing public health program to promote awareness about health risks of crystal and modifying related misconceptions. Finally, the government can establish policies to mandate sale tax for crystal producers and reduce easy access to crystal especially among youth.

Analysis of Accuracy The Tax Object Sales Value (NJOP) to Market Value with Assessment Sales Ratio Method. (Case Study In Malang City). This research is conducted to know the accuracy of determination of Tax Object Sales Value (NJOP) which determined by the government to current market value in society. This research was conducted in 5 (five) sub-districts in all areas of Malang City by taking samples of 80 land and building sales transactions in 2016-early 2017. This research uses a descriptive method with purposive sampling technique. The result is Assessment Sales Ratio in Kedungkandang District at 66%, Sukun District 68%, Klojen District 63%, Lowokwaru District 79%, and District Blimbing 70%. While for the entire area of Malang City of 69%. This shows that the Assessment Ratio in Malang City is still far from the standard set by IAAO that is 90% of its market value. The result of the mean divided by the median is 0.93 and the mean divided by the weighted mean of 1.13. This shows that there is no under assessment or over assessment, but it does not reflect the proportional assessment in Malang City area. COD (coefficient of dispersion) of 27.27% and COV (coefficient of variation) of 35.87% indicates that there is a need for reappraisal of NJOP which is set so as not to be too far from market value.

The paper discusses the government policy that encourages the emergence of co-operatives and analyzes the co-operatives in light of their growth in number. It establishes a static equilibrium and highlights the co-operatives’ adjustment process (dynamic equilibrium).The methodology/approach consists of the development of a theoretical model, using the Nash equilibrium for the co-operative market, and the determination of a static equilibrium. It presents the data which includes variable measurements for the adjustment process for agricultural, artisanal, and fishery co-operatives in order to analyze the stochastic process of entry-and-exit flow of co-operatives. Accordingly, the paper estimates the co-operatives’ growth index speed of adjustment (SOA) as a function of the mean-reversion Ornstein–Uhlenbeck (OU) process.The theoretical results indicate that co-operatives’ earnings depend on the number of co-operatives, market-demand, and the capacity constraint. They also show that the margin for new entrants is a dynamic gap that especially depends on demand, capacity constraint and the profits. The empirical results indicate that co-operatives growth-index process is significantly mean reverting for all sectors, and the speed of adjustment for artisanal co-operatives is significantly higher than for those in agriculture and the fisheries.

Traditional Fishing

The government of the People’s Republic of China (PRC) has strongly protested Indonesian fishing in the South China Sea, stating that it considered these waters to be a traditional Chinese fishing area. In fact, however, the area in question is within the Exclusive Economic Zone (EEZ) of Indonesia. This study aims to determine whether the determination of the boundaries of that EEZ was in accordance with the rights and obligations of Indonesia. The research method used was a normative law research, applying statutory and conceptual approaches. This article determines that a State’s right within its EEZ is a sovereign right and that the claims of the traditional fishing ground of the South China Sea is not justifiable, from the perspective of international maritime law. The term “traditional fishing ground” is not used in the United Nations Convention on the Law of the Sea. The determination of fishing rights in a country’s territorial waters or EEZ should be based on license by the State that has declared the EEZ. This analysis concludes that China’s claims to the South China Sea as a traditional fishing ground has no legal basis. It also states that where a coastal country’s EEZ includes a sea border with another country, the two should negotiate a bilateral agreement in accordance with applicable international law and make a commitment to mutual understanding and cooperation.

SummaryThe plasma tissue factor (TF) concentration was correlated to factor VII concentration (FVIIag) and factor VII activity (FVIIc) in 498 healthy volunteers ranging in age from 17 to 64 years. Immunoassays using monoclonal antibodies (mAbs) were developed for the determination of TF and FVIIag in plasma. The mAbs and the test systems were characterized. The mean value of the TF concentration was 172 ± 135 pg/ml. TF showed no age- and gender-related differences. For the total population, FVIIc, determined by a clotting test, was 110 ± 15% and the factor VIlag was 0.77 ± 0.19 μg/ml. FVII activity was significantly increased with age, whereas the concentration demonstrated no correlation to age in this population. FVII concentration is highly correlated with the activity as measured by clotting assay using rabbit thromboplastin. The ratio between FVIIc and FVIIag was not age-dependent, but demonstrated a significant difference between men and women. Between TF and FVII we could not detect a correlation.

SummaryThe plasminogen content was determined by a casein method in plasma and serum from 20 normal volunteers. The mean plasminogen content was found to be 10.1 ACU (the arbitrary caseinolytic unit defined in such a way that using a 3% casein solution and a digestion time of 20 min. at 37°C, 10 ACU gave an extinction of 0.300). No difference between serum and plasma regarding the plasminogen content was found.Plasminogen was determined in drained and drained plus washed clots prepared from 2 ml plasma. The highest values found in the drained clots were 0.9 ACU/clot and 0.2 ACU/clot in the drained plus washed clots.Plasminogen was also determined in drained and drained plus washed clots prepared from plasma with added purified plasminogen. The plasminogen was recovered in the washing fluid. According to these tests, then, purified added plasminogen is washed out of the clots.The plasminogen content of 20 thrombi obtained post mortem was also determined. The mean value was found to be 0.7 ACU/cm thrombus. Judging from our results, the “intrinsic clot lysis theory” is not the main mechanism of clot dissolution.

Background: The hawking of wares by children has been a serious issue confronting the Nigerian society. Children hawk in some of the most horrible conditions conceivable, where they face a serious risk of injury, chronic illness, kidnapping, rape or death. Objective: The focus of this study was to assess the perceived effects of street hawking on the well-being of children in Anyigba, Dekina Local Government Area of Kogi State. Methods: The population of this study consists of parents of the street hawkers in Anyigba while cross-sectional survey design was used through the purposive sampling technique to choose the sample size of one hundred and sixty-two (162) respondents. The validated structured questionnaire and In-Depth Interviews (IDIs) served as the instruments for the data collection respectively. The hypotheses were tested using Chi-Square at a predetermined 0.05 level of significance. The quantitative data were analysed with the aid of the SPSS (version 20). Results: The results indicated among others that street hawking had significant social implications and physical consequences on children's moral behaviour as well as health status in the study area. Conclusion: The study, therefore, concluded that the government of Kogi State should carry out an enlightenment campaign through the media and religious institutions on the negative consequences of street hawking are recommended as panacea. Also, the child right act instrument and its implementation should be strengthened in order to curb street hawking in the study area.
