Both Educational Lectures and Reference Photographs Are Necessary to Improve the Accuracy and Reliability of Psoriasis Area and Severity Index (PASI) Assessment: Results from Korean Nation-Wide PASI Educational Workshop

Proyek pembangunan prasarana pengendali banjir Tukad Sungi memiliki risiko yang cukup tinggi. Tujuan penelitian untuk mengidentifikasi, menilai dan memberikan respons terhadap risiko yang berpengaruh terhadap kinerja biaya dan waktu proyek. Penelitian dilakukan dengan metode penelitian campuran antara metode deskriptif kuantitatif dengan deskriptif kualitatif. Pengumpulan data dengan wawancara dan analisis data dengan Severity Index (SI). Hasil penelitian menunjukkan risiko yang teridentifikasi sebanyak 25 (dua puluh lima) risiko yang bersumber dari 8 (delapan) sumber risiko. Risiko yang memiliki nilai ekstrim dan berpengaruh terhadap kinerja biaya adalah adanya addendum saat pelaksanaan pekerjaan, cuaca yang berubah-ubah atau tidak menentu sehingga menghambat pekerjaan dan adanya penyesuaian dengan kondisi lapangan sehingga terjadi perubahan desain pekerjaan. Risiko yang memiliki nilai ekstrim dan berpengaruh terhadap kinerja waktu adalah adanya kekurangan pada pendanaan untuk melaksanakan pekerjaan dan adanya kesalahan dalam pengukuran lapangan untuk menentukan titik pekerjaan sehingga tidak sesuai gambar. Respon terhadap risiko diantaranya penyedia jasa menyediakan dana awal, melaksanakan addendum dengan segera, memakai data ramalan cuaca dari pihak BMKG, melakukan pengukuran ulang dan melakukan perubahan dengan segera dan meminta persetujuan pemilik pekerjaan.

Assessment Results

Uniform schedule maintenance of mining and haulage machines is one of the key conditions for increasing productive time of maintenance personnel and decreasing monthly average servicing time. Currently, Russian mines infringe regulated maintenance schedule aimed to improve output per shift. The loss of time of maintenance personnel and equipment as a consequence maintenance irregularity is never assessed. This article presents assessment results on maintenance schedule uniformity in terms of dump trucks BelAZ-7513 and BelAZ-7530 at Chernogorsky open pit mine, SUEK-Khakassia. A variant of calculation of time loss owing to inconsistent maintenance schedule for dump trucks is proposed. The loss of time by maintenance personnel and by mining/haulage machines is assessed. The fleet of dump trucks BelAZ-7513 and BelAZ-7530 is analyzed depending on overtime of operation between maintenance periods. It is recommended to improve uniformity of maintenance schedule for mining and haulage equipment.

Objectives: To evaluate anti-psoriatic activity of Phytochemicals on UV-Induced psoriasis in mouse tail model. Materials and Methods: Anti-psoriatic activity of selected phytochemicals on UV-Induced psoriasis in mouse tail model. The animals were dividing into 05 groups and each group contain 5 animals. Disease control group did not receive any treatment only exposure to UV-light, vehicle control treated with simple ointment, standard group treated with salicylic acid (1%w/w) ointment, remaining group are treated 1% and 2% selective phytochemical at two concentrations of ointment to topically on the tail skin. And the data were analysed using one way ANOVA followed by two-way ANOVA (Dunnett’s multiple comparisons test). Results: There was significant decrease in epidermal thickness (P < 0.05) as compared with control group. In 2% phytoconstituents has shown a significant reduction in the total epidermal thickness 8.4****±0.748, 7.6**±0.6781 and 8*±0.8366 in geraniol, glycyrrhizic acid and ellagic acid treated group, when compare to the disease induced animal, there was no lesion of Munro’s microabscess, capillary loop dilation along with elongation of rete ridges in the section of skin of rats. Psoriasis Severity Index was reduced in test treated groups as compared with that of disease control group. It was slowly reduced to 2nd week, totally (55-70%) reduction in PSI is observed at the time of third week of treatment period. Conclusion: The result of the study showed that the 2% of geraniol, ellagic acid, glycyrrhizicacid and hesperidin, exhibited significant activity on UV-induced psoriasis in rodents. The study implies that selected phytoconstituents are a promising research for further investigations to prove its anti-psoriatic activity.
