Analysis Of Policy Has Been Established By The Minister On Opening The Export Of Lobster Seed In Indonesia

Seakeeping is the ship's ability to stay afloat on the waves. The ship's maneuverability is greatly influenced by external factors related to the state of the sea and the waters in which the ship sails. Calculating seakeeping with various variations of depth, current, and wave height is needed for ship safety when sailing in the calculation of seakeeping using linear strip theory to calculate the response of heaving and pitching movements while roll damping theory for rolling movements. In this study, the ship's motion is calculated using the Finite element method software Hydrodynamic Diffraction and Hydrodynamic Time Response. For variations in wave height and water depth, referring to the conditions of Indonesian waters, from the reference, variations in wave height of 3 m, and 5 m (based on sea state WMO). In contrast, the current variation uses a current with a speed of 10 knots and a current depth of 10 T, 15 T, and 20 T. Based on the data obtained in data processing, it can be seen that the high value of the wave frequency obtained at 90 and 270 degrees wave direction is relatively high. The value of the roll spectrum in the direction of 0 and 270 degrees is large and can cause rolling on the ship. In the direction of 0 and 270 degrees, the wave resistance can be reduced by th Lobsters are animals that enter into crustaceans that have problematic skin. Adult lobsters can generally be found on a stretch of sand with coral spots with a depth of between 5-100 meters. This condition will cause a low number of young lobsters in the waters. This research was conducted with a case study regarding the policy of opening lobster seed export, which aims to find out how the policy is to open the export of lobster seed. The data obtained is done by reviewing the literature on the internet. Based on the analysis, the export profit of lobster seeds has continued to increase every month since it was again allowed by the government in May 2020. Based on data from the Central Statistics Agency (BPS), lobster seeds began to be re-exported in June 2020 at 32 kilograms, costing the US $ 112,990. The government can help with training and outreach on lobster cultivation. The government can offer Lobster a partnership package to help people start a freshwater crayfish business

Item analysis of multiple-choice questions in summative assessment for professional examination I of an outcome-based integrated MBBS curriculum

Background: This study presents an item analysis of multiple-choice questions (MCQ-Type A) used in the summative assessment for Professional Examination I at Defence Services Medical Academy, Yangon, Myanmar. The objectives of the study were to perform item analysis using Difficulty Index (DIF I) and Discrimination Index (DI) and to correlate between DIF I and DI. Methods: A cross-sectional observational study was conducted with 200 multiple-choice questions from two written examination papers answered by 46 medical year 2 students of Defence Services Medical Academy, Yangon, Myanmar. Item analysis of multiple-choice questions were done by using DIF I and DI calculated post-exam. Results: Results showed that the majority of items were categorized as easy based on DIF I, with 63% and 60% in Papers I and II, respectively. Only about one-third of items were deemed acceptable, and few fell into the difficult category. DI ranged from negative to excellent, with 62% and 61% of MCQs in Papers I and II showing acceptable to excellent discrimination. Items with poor discrimination (35% and 34% in Papers I and II) should be revised or discarded. Moreover, items with negative DI should be re-evaluated for potential key errors or vague wording. A low negative correlation between DIF I and DI was observed, indicating that as DIF I increased, discrimination power decreased. Notably, items with easy DIF I demonstrated a moderate negative correlation with DI, consistent with previous research. Conclusions: This study underscores the importance of item analysis to enhance the validity of assessment tools and ensure the effective evaluation of student cognition levels. Consequently, reconstruction and modification of MCQs are recommended to improve assessment quality and accurately measure student abilities

An Interesting Study of Capacity Improvement of a Shipyard in Myanmar

Abstract¾ Six shipyards are in operation under control of Engineering Department of Inland Water Transport. Among them, Dalla shipyard currently accounts for about 50 percent of repair work on ships owned by the Inland Water Transport (IWT). The efficiency of the shipyard, which is about 164 years old, is hampered by old equipment, including some from the WWII-era (Word War II). Now the shipyard needs to be upgraded to improve its current capacity in ship repair. In this study, we proposed two ways which are supporting facilities and re-layout shipyard to increase ship repair. This paper obtains two alternative layouts of shipyard. The first alternative layout does not change the existing layout of shipyard but steel plate warehouse are built. The second alternative changes the existing layout because machine shop and steel plate warehouse is too far from the slipways. The first and second alternatives renovate zone 5 shop, carpenter shop, pipe and boiler shop and repair slipways.  The two alternatives have steel plate warehouse as well as the addition of two material handling equipment mobile crane and forklift. The second alternative re-locates new machine shop near the slip ways for better material handling and time consuming. The second alternative is the best alternative in terms of economically feasible, good flow of material and perfect of technical term and the most number of ship repairs. Then it can be improved capacity amount 1.43 times and docking time can be reduced from average 33 days to 27 days

Prevalence and Risk Factors of Eye Problems among Older People in Central Tropical Region, Naypyitaw Union Territory, Myanmar

Purpose:Vision is essential one and it is proximately linked with their quality of life. In the meantime, older populations are increasing rapidly in the whole world and thus, age-related macular degeneration, glaucoma, cataract and diabetic retinopathy are becoming common. Hot and dusty environment, inadequate access to water and poor facial hygiene are risk factors for blindness. Design: Lewe Township was purposively selected due to its high prevalent on eye problems. This cross-sectional study was conducted and simple random sampling was applied to achieve desired sample size. The structured questionnaires were used to collect data including screening of eye problems from 414 older population. Frequency, percentage, mean, SD and other descriptive analysis were determined and chi-square test for associations was constructed. Findings: Cataract was the highest prevalence rate with 40.8% followed by refractive error (27.3%) and pterygium (12.8%) among older people population in research area. While knowledge level indicated good level (88.4%), good attitude level (21.3%) and good practice level (27.1%) were noticeably low among older people. In the meantime, there were significantly associations between age (p=0.003) and education level (p=0.001) with knowledge level of older people while age (p=0.001), education level (p=<0.001), occupation (p=0.038) showed statistically association with attitude level. Originality:The study noticed that higher prevalence of eye problems while relatively poor level of eye care seeking practice and unawareness on risk factors in targeted community. Knowledge and awareness for changing attitude about eye problems, eye care seeking behavior and preventive practices should be accomplished more

Mass drug administration for the acceleration of malaria elimination in a region of Myanmar with artemisinin-resistant falciparum malaria: a cluster-randomised trial

Background: To contain multidrug-resistant Plasmodium falciparum, malaria elimination in the Greater Mekong subregion needs to be accelerated while current antimalarials remain effective. We evaluated the safety, effectiveness, and potential resistance selection of dihydroartemisinin–piperaquine mass drug administration (MDA) in a region with artemisinin resistance in Myanmar. Methods: We did a cluster-randomised controlled trial in rural community clusters in Kayin (Karen) state in southeast Myanmar. Malaria prevalence was assessed using ultrasensitive quantitative PCR (uPCR) in villages that were operationally suitable for MDA (villages with community willingness, no other malaria control campaigns, and a population of 50–1200). Villages were eligible to participate if the prevalence of malaria (all species) in adults was greater than 30% or P falciparum prevalence was greater than 10% (or both). Contiguous villages were combined into clusters. Eligible clusters were paired based on P falciparum prevalence (estimates within 10%) and proximity. Community health workers provided routine malaria case management and distributed long-lasting insecticidal bed-nets (LLINs) in all clusters. Randomisation of clusters (1:1) to the MDA intervention group or control group was by public coin-flip. Group allocations were not concealed. Three MDA rounds (3 days of supervised dihydroartemisinin–piperaquine [target total dose 7 mg/kg dihydroartemisinin and 55 mg/kg piperaquine] and single low-dose primaquine [target dose 0·25 mg base per kg]) were delivered to intervention clusters. Parasitaemia prevalence was assessed at 3, 5, 10, 15, 21, 27, and 33 months. The primary outcomes were P falciparum prevalence at months 3 and 10. All clusters were included in the primary analysis. Adverse events were monitored from the first MDA dose until 1 month after the final dose, or until resolution of any adverse event occurring during follow-up. This trial is registered with ClinicalTrials.gov, NCT01872702. Findings: Baseline uPCR malaria surveys were done in January, 2015, in 43 villages that were operationally suitable for MDA (2671 individuals). 18 villages met the eligibility criteria. Three villages in close proximity were combined into one cluster because a border between them could not be defined. This gave a total of 16 clusters in eight pairs. In the intervention clusters, MDA was delivered from March 4 to March 17, from March 30 to April 10, and from April 27 to May 10, 2015. The weighted mean absolute difference in P falciparum prevalence in the MDA group relative to the control group was −10·6% (95% CI −15·1 to −6·1; p=0·0008) at month 3 and −4·5% (−10·9 to 1·9; p=0·14) at month 10. At month 3, the weighted P falciparum prevalence was 1·4% (0·6 to 3·6; 12 of 747) in the MDA group and 10·6% (7·0 to 15·6; 56 of 485) in the control group. Corresponding prevalences at month 10 were 3·2% (1·5 to 6·8; 34 of 1013) and 5·8% (2·5 to 12·9; 33 of 515). Adverse events were reported for 151 (3·6%) of 4173 treated individuals. The most common adverse events were dizziness (n=109) and rash or itching (n=20). No treatment-related deaths occurred. Interpretation: In this low-transmission setting, the substantial reduction in P falciparum prevalence resulting from support of community case management was accelerated by MDA. In addition to supporting community health worker case management and LLIN distribution, malaria elimination programmes should consider using MDA to reduce P falciparum prevalence rapidly in foci of higher transmission.

Aging-Affected MSC Functions and Severity of Periodontal Tissue Destruction in a Ligature-Induced Mouse Periodontitis Model

Mesenchymal stem cells (MSCs) are known to play important roles in the repair of lost or damaged tissues and immunotolerance. On the other hand, aging is known to impair MSC function. However, little is currently known about how aged MSCs affect the host response to the local inflammatory condition and tissue deterioration in periodontitis, which is a progressive destructive disease of the periodontal tissue potentially leading to multiple tooth loss. In this study, we examined the relationship between aging-induced impairment of MSC function and the severity of periodontal tissue destruction associated with the decrease in host immunomodulatory response using a ligature-induced periodontitis model in young and aged mice. The results of micro computerized tomography (micro-CT) and histological analysis revealed a more severe bone loss associated with increased osteoclast activity in aged (50-week-old) mice compared to young (5-week-old) mice. Immunostaining analysis revealed that, in aged mice, the accumulation of inflammatory T and B cells was higher, whereas the percentage of platelet-derived growth factor receptor alpha (PDGFR alpha)(+) MSCs, which are known to modulate the apoptosis of T cells, was significantly lower than in young mice. In vitro analysis of MSC function showed that the expression of surface antigen markers for MSCs (Sca-1, CD90, CD146), colony formation, migration, and osteogenic differentiation of aged MSCs were significantly declined compared to those of young MSCs. Moreover, a significantly higher proportion of aged MSCs were positive for the senescence-associated beta galactosidase activity. Importantly, aged MSCs presented a decreased expression of FAS-L, which was associated with a lower immunomodulatory property of aged MSCs to induce T cell apoptosis in co-cultures compared with young MSCs. In summary, this is the first study showing that aging-induced impairment of MSC function, including immunomodulatory response, is potentially correlated with progressive periodontal tissue deterioration

An Efficient Federated Learning Framework for Training Semantic Communication System

Semantic communication has emerged as a pillar forthe next generation of communication systems due to its capabilities in alleviating data redundancy. Most semantic communication systems are built upon advanced deep learning models whosetraining performance heavily relies on data availability. Existingstudies often make unrealistic assumptions of a readily accessibledata source, where in practice, data is mainly created on the clientside. Due to privacy and security concerns, the transmission ofdata is restricted, which is necessary for conventional centralizedtraining schemes. To address this challenge, we explore semanticcommunication in a federated learning (FL) setting that utilizesclient data without leaking privacy. Additionally, we designour system to tackle the communication overhead by reducingthe quantity of information delivered in each global round.In this way, we can save significant bandwidth for resourcelimited devices and reduce overall network traffic. Finally, weintroduce a mechanism to aggregate the global model fromclients, called FedLol. Extensive simulation results demonstratethe effectiveness of our proposed technique compared to baselinemethods
