Conventional antipsychotics are commonly used to treat children and adolescents suffered from schizophrenia to other neuropsychiatric conditions. Regrettably, studies for typical antipsychotics report high rates of sedation, orthostatic hypotension, and extrapyramidal side effects. Over the past few years, atypical antipsychotics have been prescribed for use in adults with psychotic symptoms. Child psychiatrists have begun using these drugs to children and adolescents hoping safe and better alternatives to the conventional antipsychotics. However, there is not enough short-term and almost no long-term data about atypical antipsychotics for pediatric patients. Therefore, the purpose of this article is to review what is known about the use of the atypical antipsychotics in young patients. To do so, an appropriate approach to the use of these drugs in child and adolescent patients my be offered.

Fructus of Rubus coreanus $M_{IQ.}$. (FRCM) has been used for stuttering urination, prostate gland disease, and impotence in Korean traditional medicine. Water extract of FRCM (WFRCM) treatment significantly attenuated airway hyperreactivity (AHR). Airway recruitment of leukocytes and eosinophils was also markedly reduced by WFRCM administration, suggesting that WFRCM can alleviate the airway inflammation. However, the level of cytokine (IL-4, IL-5, and IL-13) in bronchoalveolar lavage fluid (BALF) and lung was not different compared with positive control. WFRCM reduced the number of draining lymph node cells during OVA-induced allergic asthma. I further examined transcription level of cytokine in lung. WFRCM treatment reduced IL-4 and IL-13 mRNA in lung and inhibited IgE and IgG1 but not IgG2a. My data suggest that WFRCM attenuates OVA-induced allergic asthma through inhibition of Th2 cell response.

According to the aviation statistics, tail strike incidents and accidents are cyclic. Although many tail strikes occurred during takeoff, these are less than during landing cases. Many cases are related on human factors. In my opinion it is possible to analyze the causes of takeoff tail strikes to some extent. There are major casual factors of tail strike during takeoff such as; (1) Mis-trimmed horizontal stabilizer (2) premature rotation prior to $V_R$ (3) Excessive pitch up rate during rotation (4) Improper use of the flight director. Among these causes improper use of flight director is excluded in this paper because it is recommended that pilot should use flight director after airborne. So I analyzed the other three causes as following. Firstly, because mis-trimmed stabilizer is related to center of gravity(CG), the relationship between stabilizer and CG is reviewed. Secondly, concerned premature rotation prior to $V_R$ I reviewed the background of rotation speed($V_R$) establishment and analyzed theoretically what speed leads to tail strikes. Thirdly, concerning excessive pitch up rate during rotation I analyzed what excessive pitch up rate can decrease ground clearance while using FDR data.

Adults in their middle age are being held back by their roles through economic activities, but their rapid retirement and job sharing are adding to their anxiety. Also, it is very important to establish welfare policies for the elderly in the future because it can predict the economic situation in the old age through the economic activities of middle-aged adults. My study analyzed the 6th data of Kreis of the National Pension Research Institute's. The number of people studied is 2,552 employed people aged 40 or over 64 across the country. According to the analysis, there were more men than women. There were many high school graduates and 50s. There were many people who had spouses and who lived in the province. Wage workers represented 53.1% of the total. The lower the age, the higher the level of education, the higher the number of wage earners. Only 29% of standard workers and 30.8% of regular workers were employed. There were many economically unstable middle-aged adults. Economic instability in the middle age requires social attention because it can lead to poverty in old age. Therefore, measures should be taken to ensure stable jobs for middle-aged adults, whose spending increases more than their income.

This study seeks to add to the current understanding of learners' use of modality in argumentative writing. A learner corpus of argumentative essays on four topics was created and compared to native English speaker data from the International Corpus Network of Asian Learners of English (ICNALE). The relationship between learners' use of modal devices (MDs) and the devices' appearance in the school's curriculum was also examined. The results showed that learners relied on a very narrow range of MDs compared to those in previous studies. The frequency of use of MDs varied based on the topic and did not seem to be driven by cultural factors as has been previously suggested. Learners used more hedges than boosters on all topics, contradicting most previous studies. Curriculum was determined to have a direct correlation with MD use, and other important factors may include perception of topic and overreliance on certain MDs over others (the One-to-One principal). This research implies that learners' perception of topic should be explored further as a variable affecting MD use. Curricula should be designed based on frequency of MD use by English native speakers, and learners should receive instruction that teaches the norms of MD use in academic writing. The methodology used in the study to determine correlations between MD use and the curriculum has a wide range of potential applications in the field of Contrastive Interlanguage Analysis.

The paper examines the impact of shadow economy and corruption, along with public expenditure, trade openness, foreign direct investment (FDI), inflation, and tax revenue on the economic growth of the BRICS countries. Data were collected from the World Bank, Transparency International, and Heritage Foundation over the 1991-2017 period. The Bayesian linear regression method is used to examine whether shadow economy, corruption and other indicators affect the economic growth of countries studied. This paper applies the normal prior suggested by Lemoine (2019) while the posterior distribution is simulated using Monte Carlo Markov Chain (MCMC) technique through the Gibbs sampling algorithm. The results indicate that public expenditure and trade openness can enhance the BRICS countries' economic growth, with the positive impact probability of 75.69% and 67.11%, respectively. Also, FDI, inflation, and tax revenue positively affect this growth, though the probability of positive effect is ambiguous, ranging from 51.13% to 56.36%. Further, the research's major finding is that shadow economy and control of corruption have a positive effect on the economic growth of the BRICS countries. Nevertheless, the posterior probabilities of these two factors are 62.23% and 65.25%, respectively. This result suggests that their positive effect probability is not high.

With the global COVID-19 pandemic, the tourism sector and all consumption have contracted with the untact era. Wine will also be sold and developed in various ways non-face-to-face in the future. Therefore, it is necessary to develop apps and web servers that focus on health in the era of single-person households and non-face-to-face. This study used facial recognition data based on photos of adult men and women in their 40s and 50s to analyze the Sasang constitution through a mobile app and web server, and suggested wine recommendations suitable for their constitution. First, the user's body information is entered. And through the facial recognition mobile app, recommend the right wine after analyzing the body type. if it's not like the first recommended wine, it is configured to receive another wine recommendation. In the future, the number of single-person households will increase further, and in the age of well-being, wine recommendations that fit my body will be useful. Wine recommendation suitable for Sasang constitution will be a useful mobile application to manage personal healt
