ปัญหาด้านการตกต่ำด้านราคาของผลผลิตผลไม้ประเภทมะม่วงเป็นปัญหาสำคัญในปัจจุบัน โดยเฉพาะอย่างยิ่งกับมะม่วงพันธุ์มหาชนกที่มีการเติบโตในการส่งออกอย่างมากเมื่อเทียบกับมะม่วงสายพันธุ์อื่น เนื่องจากเป็นมะม่วงที่มีสีสันสวยงาม มีกลิ่นหอม ปัญหาการตกต่ำด้านราคาเกิดจากมีผลผลิตที่ไม่ผ่านเกณฑ์คุณภาพการส่งออกทำให้เกิดผลผลิตที่ไม่ผ่านคุณภาพนำกลับมาขายในประเทศในราคาถูก บางกรณีเกษตรกรจำเป็นต้องละทิ้งผลผลิตดังกล่าว จากปัญหาที่เกิดขึ้นจึงมีแนวคิดนำมะม่วงดังกล่าวมาสกัดสารหอมระเหยจากเปลือกของมะม่วงเพื่อจะคงสภาพสารระเหยและนำไปพัฒนาเป็นผลิตภัณฑ์ต้นแบบด้านกลิ่นรวมทั้งการศึกษาปัจจัยทางแสงที่ส่งผลต่อการแสดงสีผิวเปลือกเพื่อทำการเปลี่ยนแปลงสีบนผิวเปลือกผลไม้ให้มีความโดดเด่นจากธรรมชาติความสวยงามของผลมะม่วงที่มีสีสม่ำเสมอด้วยปัจจัยทางแสงที่มีความยาวคลื่นและพลังงานที่แตกต่างกัน โดยการศึกษาการเปลี่ยนแปลงเปลือกนอกเมื่อได้รับแสงโดยไม่ได้เกิดจากการสุกของผลมะม่วง องความรู้ที่ได้สามารถต่อยอดไปสู่การสร้างระบบนวัตกรรมต้นแบบ และสามารถนำเสนอนวัตกรรมที่ได้ต่อยอดสู่เกษตรกรหรือผู้ประกอบการที่สนใจและเพื่อประยุกต์ใช้งานด้านต่าง ๆ ต่อไป

Threadfin breams is an economically important fish that can be found in fisheries in both the Gulf of Thailand and Andaman Sea and is cheap. In addition, the consumption of raw fish as sashimi is increasingly popular in Thailand. Therefore, it is necessary to promote its consumption to increase its value. This study investigated the preservation of threadfin breams (N. furcosus) for raw or sashimi consumption. The preservation of threadfin breams consisted of Ikejime (K) and cold seawater (S) methods, and the preservation of the fish by Gutting (G) and whole (W) and storing for 3 days on ice (I) or in a refrigerator (F). The freshness quality of threadfin breams was evaluated by sensory, physicochemical (TVB-N, TMA-N and pH), freshness index (Ki-value) and microbiological methods. It was found that after being stored for 3 days, the KGF group of threadfin breams had the highest overall sensory score, which was 8.36±0.80 points, and the KWI, SWI and SWF groups of threadfin breams had the lowest overall sensory scores, which were 8.13±0.77, 8.13±0.77 and 8.13±0.81 points, respectively. And the overall sensory scores of all experimental groups of fish increased significantly (p<0.05). The TVB-N value of threadfin breams in KGF group had the lowest TVB-N value, which was 1.37±0.93 mg nitrogen/100 g sample. The threadfin breams in SGI group had the highest TVB-N value, which was 2.36±1.15 mg nitrogen/100 g sample. The TVB-N of fish in all experimental groups increased significantly (p<0.05). The TMA-N value of threadfin breams in KGF group had the lowest TMA-N value, which was 1.56±0.88 mg nitrogen/100 g sample. The threadfin breams in SWF group had the highest TMA-N value, which was 2.17±1.22 mg nitrogen/100 g sample. The TMA-N of fish in all experimental groups increased significantly (p<0.05). The pH value of threadfin breams in KGF group had the lowest pH value, which was 6.40±0.12. The threadfin breams in SWF group had the highest pH value, which was 6.78±0.25. The pH of fish in all experimental groups increased significantly (p<0.05). Ki value The threadfin breams in KGF group had the lowest Ki value, which was 9.05±0.73%. The threadfin breams in KWI group had the highest Ki value, which was 12.88±4.19%. The Ki value of all experimental groups of fish increased without statistical significance (p>0.05). In terms of freshness quality in microbiology, it was found that in all experimental groups, Salmonella spp., S. aureus, B. cereus, C. perfringens and E. coli were found in all experimental groups of threadfin breams. All types of microorganisms in all groups of threadfin breams increased with statistical significance (p<0.05). When compared with the freshness quality criteria in terms of sensory, chemical, physical, freshness index and microbiology, it was found that all groups of threadfin breams were very fresh and suitable for raw consumption during the preservation and storage for 3 days. After 3 days of storage, the threadfin breams should be consumed cooked because the freshness quality of the fish is not suitable for raw consumption due to the increase in various parameters. The increase in various parameters is due to the deterioration of the fish and the activities of microorganisms. Therefore, threadfin breams is suitable to promote raw consumption within 3 days of storage. In addition, fish preservation, especially by Ikejime method, then cutting open the belly and storing in the refrigerator, can help improve the freshness of the fish. The results of this study can be used to develop techniques for preserving fish after capture for fishermen and can promote the increase in the value of threadfin breams in the future.

KinderForest : Puzzle Building Game with VR Technology is designed to utilize Virtual Reality (VR) technology with the primary aim of promoting creative problem-solving skills and basic practical application abilities among players. This project presents the game in an Augmented Virtual Reality (AR VR) format, emphasizing physical engagement of players during gameplay while fostering creativity and fundamental application skills. The project team has chosen to utilize Unreal Engine 5.1 and Oculus Quest 2 virtual reality glasses to develop the game in the form of augmented virtual reality technology. Within the game, there will be various levels that require creative thinking and different approaches to pass. Time constraints will be a crucial element in completing missions and progressing through these levels. Players will physically move their bodies in response to in-game movements. Each level will present unique challenges that will necessitate both physical movement and problem-solving skills. The game will provide different rewards based on the outcomes of mission completion, and players will be informed of their results once they have successfully passed a level.

Soil is home to a diverse array of living organisms that interact within a complex food web, facilitating energy and nutrient cycling essential for sustaining life above ground. Among these organisms, soil microbes play a crucial role in supporting plant growth. Beneficial microorganisms enhance nutrient availability, improve soil structure by increasing porosity, and strengthen plant resistance to diseases. Conversely, harmful microorganisms, such as plant pathogens, can hinder plant growth and reduce crop yields when present in high concentrations. Neutral microorganisms, which naturally inhabit the soil, contribute to the soil ecosystem without directly impacting plants. A single teaspoon of soil contains over a billion microorganisms, yet only about 1% of them can be cultured in laboratory conditions. This highlights soil as one of the richest reservoirs of microbial diversity on Earth.
