  • Vibrio harveyi belongs to the Vibrio genus that causes vibriosis in marine and aquatic fish species through double-stranded DNA virus replication. In humans, around 12 Vibrio species can cause gastroenteritis (gastrointestinal illness). A large amount of virus particles can be found in the cytoplasm of infected cells, which may cause death. Despite these devastating complications, there is still no cure or vaccine for the virus. As a result, we used an immunoinformatics approach to develop a multi-epitope vaccine against most pathogenic hemolysin gene of V. harveyi. The immunodominant T- and B-cell epitopes were identified using the hemolysin protein. We developed a vaccine employing three possible epitopes: cytotoxic T-lymphocytes, helper T-lymphocytes, and linear B-lymphocyte epitopes, after thorough testing. The vaccine was developed to be antigenic, immunogenic, and non-allergenic, as well as having a better solubility. Molecular dynamics simulation revealed significant structural stiffness and binding stability. In addition, the immunological simulation generated by computer revealed that the vaccination might elicit immune reactions in the actual life after injection. Finally, using Escherichia coli K12 as a model, codon optimization yielded ideal GC content and a higher codon adaptation index value, which was then included in the cloning vector pET2+ (a). Altogether, our experiment implies that the proposed peptide vaccine might be a good option for vibriosis prophylaxis.

  • The two complete mitochondrial genomes (mitogenomes) of Paedocypris progenetica, the smallest fish in the world which belonged to the Cyprinidae family, were sequenced and assembled. The circular DNA molecules of mitogenomes P1-P. progenetica and S3-P. progenetica were 16,827 and 16,616 bp in length, respectively, and encoded 13 protein-coding genes, 22 transfer RNA genes, two ribosomal RNA genes, and one control region. The gene arrangements of P. progenetica were identical to those of other Paedocypris species. BLAST and phylogenetic analyses revealed variations in the mitogenome sequences of two Paedocypris species from Perak and Selangor. The circular DNA molecule of P. progenetica yield a standard vertebrate gene arrangement and an overall nucleotide composition of A 33.0%, T 27.2%, C 23.5%, and G 15.5%. The overall AT content of this species was consistent with that of other species in other genera. The negative GC-skew and positive AT-skew of the control region in P. progenetica indicated rich genetic variability and AT nucleotide bias, respectively. The results of this study provide genomic variation information and enhance the understanding of the mitogenome of P. progenetica. They could later deliver highly valuable new insight into data for phylogenetic analysis and population genetics.

  • 이동통신 시스템에서 정확하고 신속한 통신망 구축은 중요하다. 현재 무선통신 시스템을 구성하기 위해서는 셀 플래닝 장비를 통해 기지국의 파라미터를 설정한다. 하지만 기지국의 신규 설치마다 셀 플래닝을 새로 수행해야 하며, 셀 플래닝에 반영되지 않은 장애물 정보 등 실제 환경과 맞지 않는 파라미터가 설정되는 문제가 발생할 수 있다. 이 논문에서는 SON 서버에서 기지국의 위치와 단말의 측정 정보를 이용한 DNN 모델을 통해 경로 손실 예측을 수행하고, 지형을 구분하는 CNN 모델을 통해 예측된 경로 손실의 지형을 구분한다. 구분된 지형을 바탕으로 SON 서버에서 해당 지형에 맞는 지형별 기지국 파라미터를 자동으로 설정하고 지속해서 지형별 파라미터를 업데이트하여, 지형과 주변 환경 변화를 고려한 기지국 파라미터를 자동으로 설정할 수 있다.

  • Nervous necrosis virus (NNV) is a deadly infectious disease that affects several fish species. It has been found that the NNV utilizes grouper heat shock cognate protein 70 (GHSC70) to enter the host cell. Thus, blocking the virus entry by targeting the responsible protein can protect the fishes from disease. The main objective of the study was to evaluate the inhibitory potentiality of 70 compounds of Azadirachta indica (Neem plant) which has been reported to show potential antiviral activity against various pathogens, but activity against the NNV has not yet been reported. The binding affinity of 70 compounds was calculated against the GHSC70 with the docking and molecular dynamics (MD) simulation approaches. Both the docking and MD methods predict 4 (PubChem CID: 14492795, 10134, 5280863, and 11119228) inhibitory compounds that bind strongly with the GHSC70 protein with a binding affinity of -9.7, -9.5, -9.1, and -9.0 kcal/mol, respectively. Also, the ADMET (absorption, distribution, metabolism, excretion, and toxicity) properties of the compounds confirmed the drug-likeness properties. As a result of the investigation, it may be inferred that Neem plant compounds may act as significant inhibitors of viral entry into the host cell. More in-vitro testing is needed to establish their effectiveness.

  • According to long-term projections, by 2030, the world's population is predicted to reach 7.5 billion individuals, and there will be roughly 27 million new cancer cases diagnosed. The global burden of breast cancer (BC) is expected to rise. According to the Ministry of Health-Iraqi Cancer Registry, cancer is the second largest cause of death after cardiovascular disease. This study investigated the interleukin-18 (IL18) single-nucleotide polymorphisms (SNPs) -607C/A rs1946518 and -137G/C rs187238 using the sequence-specific amplification-polymerase chain reaction approach. Regarding the position -607C/A, there was a highly significant difference between the observed and expected frequencies in patients and controls (χ2 = 3.16 and χ2 = 16.5), respectively. The AA and CA genotypes were associated with significantly increased BC risk (odds ratio [OR], 3.68; p = 0.004 and OR, 2.83; p = 0.04, respectively). Women with the A allele had a 5.03-fold increased susceptibility to BC. The C allele may be a protective allele against BC (OR, 0.19). Although position -137G/C showed no significant differences in the CC genotype distribution (p = 0.18), the frequency of the CC genotype was significantly higher in patients than in controls. In contrast, patients had a significantly higher frequency of GC genotypes than controls (p = 0.04), which was associated with an increased risk of developing BC (OR, 2.63). The G allele frequency was significantly lower in patients than in controls (55.0% vs. 76.2%, respectively). This SNP may be considered a common genotype in the Iraqi population, with the wild-type G allele having a protective function (OR, 0.19) and the mutant C allele having an environmental effect (OR, 2.63).

  • Purpose : It is necessary to demonstrate the effect of non-invasive and non-pharmacological interventions such as manual therapy and therapeutic exercise for the management of nonspecific neck pain. In the present study, we aimed to investigate the efficacy of myofascial release therapy plus therapeutic exercise for disability owing to neck pain and quality of life in individuals with nonspecific neck pain. Methods : Eighteen participants with nonspecific neck pain were randomly allocated to intervention (n=9) and control groups (n=9). The intervention group received a myofascial release therapy for 20 min and performed neck stabilization exercises for 30 min twice a week for 4 weeks. The control group performed neck stabilization exercises for 30 min twice a week for 4 weeks at the same time points as the intervention group. Disability owing to neck pain and quality of life were quantified using the neck disability index (NDI) and the Korean version of the World Health Organization Quality of Life Brief Version (WHOQOL-BREF), respectively. NDI and WHOQOL-BREF were assessed before and after intervention. Results : The disability owing to neck pain significantly changed between the groups over time (total score of NDI, p=.049). There were significant time and group interactions in pain (pain intensity of NDI, p=.035) and concentration (concentration of NDI, p=.049). Personal care, lifting, reading, headaches, work, driving, sleeping, and recreation did not show significant improvement between the groups over time. Total score, overall quality of life and general health, physical health domain, psychological domain, social relationships domain, and environmental domain quantified by WHOQOL-BREF did not show significant improvements between the groups over time. Conclusion : These results suggest the clinical use of myofascial release therapy in addition to therapeutic exercise for the management of nonspecific neck pain. Further studies are needed to generalize the findings of this study.

  • Background: Obesity is a major public health problem that is causally related to serious medical conditions. In this study, the public health implications of obesity based on body mass index (BMI) with anthropometric measures among adults in the Republic of Korea and Japan in 2019 were compared. Methods: A simple cross-section, nationally representative of the raw data from the National Health and Nutrition Examination Survey in 2019 between Korea and Japan were used. We analyzed the data of those categorized as obese with a BMI of ≥25 kg/m2 according to the World Health Organization Expert Consultation. Results: The average values of BMI based on body height and body weight among males and females in Korea were 24.6±0.08 and 23.3±0.09, respectively; those in Japan were 23.9±0.08 and 22.6±0.08, respectively. The measured anthropometric values were obviously higher in Korean than in Japan (P<0.01). The prevalence rates (PRs) of obesity by sex in Korea were 41.4% among males and 27.3% females; those in Japan were 32.5% among males and 22.0% among females. The statistically significant results showed that the total obesity rate was higher in males than in females in both countries (P<0.01). The PRs of obesity in Korea were 41.4% in males and 27.3% in females; those in Japan were 32.5% in males and 22.0% in females. The statistically significantly PR of total obesity among Korean adults was greater than that among Japanese adults (P<0.01). Conclusion: The PR of obesity in Korea relative to that in Japan showed a gradually increasing trend. Obesity is a major problem, especially in the pilot group. Reducing the prevalence of obesity among pilots is important for reducing in-flight medical incapacitation and ensuring flight safety. Obesity management is necessary to prevent obesity-related diseases and promote pilot health.

  • 21세기의 핵심역량 중 하나인 창의성은 사회구성원의 필수 항목으로 요구되다. 원하는 방향으로 사용할 수 있도록 하는 개성적인 측면에서 그 능력을 강조한다. 그러나 창의성은 새로운 아이디어나 제품을 만들어내는 것뿐만 아니라 변화하는 환경에 적응하고 문제를 해결하는 등 조직의 긍정적인 변화에 기여하는 것으로 간주되다. 이에 따라 선행연구를 검토하여 보상이 창의성을 촉진하거나 방해할 수 있다는 결론을 내렸으며, 이는 보상의 성격과 연구자가 보유한 창의성 개념, 개인차 및 외부 환경에 따라 달라질 수 있다. 우리는 또한 보상이 동기, 인지 및 합성 기능을 통하여 창의성에 영향을 미칠 수 있다고 제안하였다. 분석을 바탕으로 보상이 창의성에 미치는 영향을 구체적으로 모델을 제안하였다. 본 연구는 기존의 연구를 기반으로 하며, 어떠한 외적 동기와 내적 동기가 어떠한 관계를 가지고 있는지 비교를 바탕으로 창의성에 영향을 미치는 과정에서 작용하는 다양한 요소와 메커니즘을 분석하였다. 다음으로, 보상은 사람마다 환경적 상황에서 주어지는 방식에 따라 다른 것으로 나타났다. 마지막으로 다양한 유형의 창작과제를 보상함으로써 적극적인 보상의 역할을 확보할 수 있다.

  • Analyzing the psychological and pedagogical literature, we showed the interest of researchers in the problem posed. The concept of competence is considered, which is interpreted as giving the key to solving a wide range of educational and life tasks. Research competence implies the ability to cooperate, enter into contacts, readiness for changes, for self-determination and is an integral quality of the individual, expressed in the readiness and ability to independently search for solutions to new problems and creative transformation of reality based on a set of personal and meaningful knowledge, skills, methods of activity and value attitudes.The article offers conditions that certify the improvement of forms and methods of training students in the formation of research competence of future specialists. The use of innovative technologies contributes to improving the level of training of future specialists: students are better prepared for classes, take an active part in the assimilation of program material in laboratory classes. It is noted that this creates a subject-subject relationship between the student and the teacher, and changes the attitude of students to classes. In the process of such organization of educational activities, students are convinced of the need for knowledge and its effectiveness, learn to compare, generalize, classify, establish cause-and-effect relationships, express opinions, defend their point of view, they ensure success in their studies, and develop research competence. It is proved that in order to apply the latest technologies, the teacher himself must know them well, that is, constantly improve himself, master new methods, techniques, ideas, which will help him create new pedagogical technologies and implement them in the educational process.
