Podostemaceae a family of aquatic flowering plant restricted to river rapids and waterfalls are widely reported to be the high incidence of endemism and in need for conservation. The present study analyses endemism and conservation status of the Podostemaceae in northeastern floristic region Thailand using past and current taxonomic records personal field collections geographic ranges IUCN assessment and a combination of river number in which a species occurs. The plants grown in one river and two rivers are considered as narrow endemic species. Among the six genera and 22 species recognized two genera are endemic eighteen species are endemic to Thailand eleven species of the 18 are narrowly distributed and confined in northeastern floristic region and the other 4 species are not endemic. Considering the conservation status two species are classified as Critically Endangered distributed in a single river ten species as Vulnerable distributed in 1-2 rivers six species as Near Threatened two species as Least Concern and two species as Data Deficient. Loei province is the most species-rich area in Thailand with 12 species five of them are restricted in Loei.

To manipulate students data which participate in activity projects of the university. Student activity management information system support working of student development division to know how many students join campus activities in each year. This information can increase efficiency for clubs and staffs to set up proper activities according to student requirement. Each student activities data will be printed in activities transcript report when graduate that help rising employment rate in the future. The system was developed tested and assessed by 5 experts get a good level of satisfaction in whole process. The average result of the assessment is 3.99 and standard deviation is 0.38. In conclusion the system accomplishes in good quality able to enhance management of student activity system effectively.

Recent explorations of Podostemaceae have discovered 2 new species to science (Dalzellia TWA-216 และ Hydrobryum TWA-198) from Phitsanulok Province and 3 more genera and six more species from previously known (2 genera and 4 species). Totally five genera and 10 species occur in Phitsanulok and Phetchabun provinces. Based on morphological and molecular evidence the taxa are classified into subfamily Tristichoideae including 2 genera and 3 species (Dalzellia 2 spp. and Terniopsis 1 sp.) and subfamily Podostemoideae consisting 3 genera and 7 species (Hanseniella 1 sp. Hydrobryum 5 spp. and Thawatchaia 1 sp.). The species found in both provinces are Hy. phetchabunense and Hy. tardhuangense while D. kailarsenii is found only in Phetchabun. The plants discovered only in Phitsanulok include Dalzellia TWA-216 Hydrobryum TWA-198 Han. heterophylla Hy. bifoliatum Hy. kaengsophense Th. trilobata and T. minor. Among the species found Hy. tardhuangense and Th. trilobata are also distributed to the Lao PDR and the rests are endemic to Thailand.

This paper presents an Information system for the management of the building and location. By the building Class room Timetable Schedule Photos building and Photo structure for building put on to collect the necessary information and can be easy accessed through the presentation with a web browser making agencies can be useful to use it is the And can be checked The system can allocate a code to bring the teaching of information management department is properly registered. And data to help executives make decisions about planning and building for the future. The assessment of the system’s quality was performed by 6 experts which discovered the system had a good level of satisfaction. The result of the evaluation from experts found mean at 4.00 with standard deviation at 0.36 In conclusion this system achieved all goals and gained a high level of satisfaction from all user
