KOMPARASI STRUKTUR PERTUNJUKAN WAYANG KULIT JAWA DENGAN BALI DALAM LAKON ARJUNA WIWAHA
Abstract
This research compares and contrasts the structure of Javanese Wayang Kulit (Shadow Puppet) Theatre and th performance of Balinese Shadow Theatre, enacting the same story derived from Arjuna Wiwaha poem. This research is primarily based on our experiences as both dalang practicioner and instructor, interviewing several Javanese and Balinese dalangs, and field research in Surakarta and Bali. Major part of this research analyzes the performance dramatic structure that includes the plot, setting, characterization, theme, and edification. In comparing yhe performance of both types of Wayang shadow theatre there are similarity, diversity, and overlapping structure of the two Wayang theatres
Status of Average-x from Lattice QCD
As algorithms and computing power have advanced, lattice QCD has become a
precision technique for many QCD observables. However, the calculation of
nucleon matrix elements remains an open challenge. I summarize the status of
the lattice effort by examining one observable that has come to represent this
challenge, average-x: the fraction of the nucleon's momentum carried by its
quark constituents. Recent results confirm a long standing tendency to
overshoot the experimentally measured value. Understanding this puzzle is
essential to not only the lattice calculation of nucleon properties but also
the broader effort to determine hadron structure from QCD.Comment: proceedings for 3rd International Workshop on Nucleon Structure at

Understanding Parton Distributions from Lattice QCD
I examine the past lattice QCD calculations of three representative
observables, the transverse quark distribution, momentum fraction, and axial
charge, and emphasize the prospects for not only quantitative comparison with
experiment but also qualitative understanding of QCD.Comment: Talk presented at 13th International Workshop on Deep Inelastic

Retrospective evaluation of depression screening process among older adult patients in primary care for quality improvement.
Background: Depression is not a normal process of aging; it is a diagnosable and treatable medical condition. The US Preventive Services Task Force (USPSTF) recommends that older adults be screened for depression annually.
Aim: The purpose of this evidence-based practice (EBP) project was to evaluate the depression screening process for older adults (age 65+) in a primary health care setting and provide recommendations to the primary health care clinic for improving it.
Methods: This EBP project involved collecting retrospective data from August to October 2022, including aggregate data (demographics), from all older adults who were seen in a primary health care clinic over a 3-month period, and individual data (demographics, diagnoses, chief complaint, PHQ-9 score, and what happened as a result of the screening) via medical records review.
Analysis: Descriptive statistics were conducted to: 1) describe the sample; 2) determine the percentage of older adults screened for depression (via PHQ-9); and 3) describe the outcomes associated with the screening.
Findings: The clinic reported a total of 702 encounters with older adults. Two (2) patients were screened for depression during their visit with the primary care provider (PCP). Approximately 54% of the older adult patients had completed a depression screening in the last year.
Conclusions: Key steps to ensure depression screening that meets EBP recommendations include: 1) policy development for depression screening; 2) education on depression, screening, tools, and execution; 3) and policy promotion.

Generation and Evaluation of Reference Samples as part of an Evacuated Canister Interlaboratory Study
Evacuated canisters offer an opportunity to expand on the way volatile organic compounds (VOCs) are measured in indoor air quality investigations, industrial hygiene assessments, and emergency response scenarios. There is a growing need for alternative sampling methods for VOCs as traditional sorbent tube sampling methods may not adequately capture the multitude of chemicals present in mixed exposure environments due to sorbent-analyte specificity.;This study is part of a larger work designed to address this need across a suite of 17 VOCs. This study assesses generation and evaluation methods for the production of reference evacuated canister samples as part of an ASTM-style interlaboratory study. The interlaboratory study was designed to assess evacuated canister method performance for the development of a National Institute for Occupational Safety and Health (NIOSH) Manual of Analytical Methods protocol.;The reference canister samples were generated in two concentration ranges (part-per-million and part-per-billion) and at three nominal concentration levels within the two ranges. For the PPB range, samples were generated using either a flow-based dilution or combination pressure dilution and canister-to-canister transfer technique. For the PPM range, samples were generated by either the combination pressure dilution and canister-to-canister transfer technique, or a manifold dilution method. The reference canister samples were analyzed via gas chromatography-mass spectrometry (GC-MS). The performance of three preparation methods and three analytical methods were assessed by the NIOSH 95% confidence interval on accuracy criterion.;Results indicate that method accuracy is concentration dependent with respect to certain combinations of analytical method, preparation technique, and analyte. Some sample preparation techniques were found to be better for certain groups of compounds and at certain concentration ranges. All 17 VOCs passed the NIOSH accuracy criterion for the PPM range when prepared using the pressure dilution technique and analyzed via a 1 cc loop injection into a GC-MS. For the PPB range of concentration levels, 15 VOCs passed the NIOSH accuracy criterion when prepared by the pressure dilution method and analyzed via a 250 cc, cryogenically concentrated injection into a GC-MS
