Introduction: The Concept2 SkiErg is increasing in popularity and is widely used to provide a low impact total body workout. Because of these benefits, the SkiErg could be an ideal tool for fitness testing. Therefore, the purpose of this study was to compare VO2peak values elicited from a treadmill (TM) and SkiErg (SE) graded exercise test (GXT). Methods: Twenty-two averagely fit females completed 2 GXT protocols to volitional exhaustion on a TM and SE. Peak VO2, HR, VE, TTE, and RER were compared using paired-samples t-tests with significant differences at p≤0.05. Max RPE was compared using a Wilcoxon Signed Rank Test. Results: TM was significantly greater than SE for VO2peak (43.82±1.07 vs 33.97±5.01 ml/kg/min, p<0.01), HR (189±8 vs 182±11 bpm, p<0.01), RPE (18.91+1.11vs 17.26+2.03, p=0.02), VE (95.44±11.26 vs 86.21±2.90 L/min, p=0.015), and TTE (550.16+137.56 vs 391.86±81.20 sec, p<0.01). RER was significantly greater on the SE (1.16±0.08 vs 1.12±0.06, p=0.024). Conclusion: Results suggest that TM elicits higher max values for VO2, HR, TTE, VE, and RPE compared to SE, while SE elicits a higher RER in the current population. SE could be used as an alternative mode of testing in averagely-fit females but does not directly compare to TM values.

The purpose of this study is to investigate the reaction of the Indonesian capital market to the announcement of a reduction in the Bank Indonesia 7-Day Reverse Repo Rate on the property and banking sectors. This study employs an event study with a seven-day observation period. The sampling technique used was the purposive sampling technique. The sample size for the banking sector was 32 companies, and the sample size for the property sector was 30 companies. Anomaly returns were used to gauge market reaction. The researchers used the paired samples t-test and the Wilcoxon signed rank test to analyze the data. The results for both sectors revealed that no market reaction was detected as a result of the announcement. This may be caused by investors thought that the announcement can’t affect the company's performance in short term and also considering the other sentiments.

Time Point

The present paper deals with the current as well as hotly debated issue of increasing attention on the extent of governance practices followed by the corporates. In particular, it investigates the disclosure of sound board practices followed by the top listed companies in India by relying upon a Voluntary Board Governance Disclosure Index (VBGDI) developed in the study. The index has been constructed by following the requirements stated under Revised Clause 49 of the Listing Agreement (2004) and Corporate Governance Voluntary Guidelines (2009). In addition, the study has covered two time points in its dataset in order to examine an improvement in the disclosure of board governance practices by the corporates from the time point 1 (2005-06) to the time point 2 (2009-10). The testing has been performed by means of paired samples t-test and Wilcoxen signed rank test (for robustness testing) which has reported significant improvement for some selected board practices in particular and for overall disclosure score as a whole. Overall, the analysis suggests that the corporate voluntary disclosure of the board governance practices has been improved (but only for some items), however, there are certain influential practices which should be covered by the companies in the ambit of their governance frameworks so that the level of governance standards in India can be upraised. On the whole, it suggests the companies to incorporate more board governance practices in the spectrum of their governance disclosures.

IntroductionAnxiety and mood disorders are common in adolescence and predict poor mental health outcomes and low quality of life in adulthood. Although early intervention seems to be critical, dropouts in the early stages of treatment are frequent and associated with low insight and severe symptoms. Therefore, a diagnostic assessment phase aimed to increase insight and early reduce symptoms appears to be essential in adolescents.ObjectivesThe objective of this study is to demonstrate that the diagnostic method Cooperative Assessment is able to early reduce symptoms in adolescents with anxiety and mood disorders.MethodsA sample of 88 patients, aged 14–19 years were included. All were recruited at the first visit and evaluated with the Cooperative Assessment. This manualized procedure was created from principles of collaborative and therapeutic assessment and aim to involve the patient in a co-developed diagnosis thorough the collaborative use of test results. Patients were evaluated before (T0), in the middle (T1) and after (T2) the assessment using CGI, GAF, HAM-A, HAM-D and MRS scales.ResultsEighty-eight adolescents, 56.8% females, diagnosed with anxiety (47.7%) and mood disorders (52.3%) completed the protocol. HAM-A, HAM-D, MRS, CGI and GAF significantly improved at T1 and T2 with respect to T0 (T0: HAM-A 17.31 ± 8.22; HAM-D 16.97 ± 8.37; MRS5.78 ± 6.17; GAF 59.3 ± 11.06; CGI 3.63 ± 1.35; T2: HAM-A 11.41 ± 6.82; HAM-D 11.1 ± 6.91; MRS3.82 ± 3.87; GAF 67.5 ± 10.76; CGI 3.03 ± 1.26; P < 0.001; Wilcoxon signed-rank test for repeated measures).ConclusionsCooperative assessment is able to early improve symptoms in adolescents with mood and anxiety disorders.Disclosure of interestThe authors have not supplied their declaration of competing interest.

The Difference

Abstract PD-1 has a role in regulating the response of the immune system to the cells of the human body. Paris et al. reported that combination antiretroviral therapy did not change % CD4+ of PD-1highCTLA-4lowCD127high early/intermediated T cells of human immunodeficiency virus infected patients but increased the percent of the marker limited to initial CD4 counts <200 with Wilcoxon signed-rank test. We hypothesized that the treatment increased the marker value in patients whose initial marker value is less than a particular value and decreased the marker value in other patients and that the test misleadingly concluded that the treatment did not change the marker value. General subgroup analyses correctly estimate the statistical significance of such a reaction or difference between such reactions only when the reaction of both of subgroups or both difference between such subgroups is statistically significant. We propose Ishida’ t-test for paired samples that can correctly judge the probability without division of the group into subgroups, and Ishida’ t-test for unpaired samples that can correctly judge the statistical significance of the difference between such reactions. We also showed that many treatments cause such increase and decrease of marker values relating PD-1 of subjects.

Breast Care

Breastfeeding is a normal process following childbirth. However, post partum mothers often complain several problems during breastfeeding. A problem that is often complained of by post partum mothers is the lack of breast milk supply. The lack of breast milk production will interfere with the process of breastfeeding, which is one of the causing factors as to why certain mothers do not exclusively breastfeed. To find out the effect of breast care and oxytocin massage on increasing milk production in post partum mothers. This research uses a quasi-experimental design. The population in this study were all primiparous post partum mothers with lactation period of 0-7 days. A total of 20 mothers participated in this study and was divided into two groups namely the treatment group and the comparison group. The samples were obtained using purposive sampling. There are independent variables (breast care and oxytocin massage) and dependent variables (milk production). Data collection was performed using a questionnaire, then analyzed using the test Wilcoxon Signed Rank Test and Mann Whitney Test. Wilcoxon Signed Rank Test Results of breast milk production of (p = 0.003) in the treatment group, while in the comparison group the breast milk production was (p = 0.014). The Mann Whitney Test results show that p = 0.004. It can be concluded that breast care and oxytocin massage effectively increase the milk production of post partum mothers. The therapy is recommended for health professionals to apply breast care and oxytocin massage to increase the milk production of post partum mothers who have less milk production. Combination of breast care and oxytocin massage have more effective benefits in increasing the breast milk production of postpartum mothers.

ABSTRACT The fourth-generation QuantiFERON test for tuberculosis infection, QuantiFERON-TB Gold Plus (QFT-Plus) has replaced the earlier version, QuantiFERON-TB Gold In-Tube (QFT-GIT). A clinical need exists for information about agreement between QFT-Plus and other tests. We conducted this study to assess agreement of test results for QFT-Plus with those of QuantiFERON-TB Gold In-Tube (QFT-GIT), T-SPOT.TB (T-SPOT), and the tuberculin skin test (TST). Persons at high risk of latent tuberculosis infection (LTBI) and/or progression to tuberculosis (TB) disease were enrolled at the 10 sites of the Tuberculosis Epidemiologic Studies Consortium from October 2016 through May 2017; each participant received all four tests. Cohen’s kappa (κ) and Wilcoxon signed-rank test compared qualitative and quantitative results of QFT-Plus with the other tests. Test results for 506 participants showed 94% agreement between QFT-Plus and QFT-GIT, with 19% positive and 75% negative results. When the tests disagreed, it was most often in the direction of QFT-GIT negative/QFT-Plus positive. QFT-Plus had similar concordance as QFT-GIT with TST (77% and 77%, respectively) and T-SPOT (92% and 91%, respectively). The study showed high agreement between QFT-GIT and QFT-Plus in a direct comparison. Both tests had similar agreement with TST and T-SPOT.

This research aims to study the effect of inquiry learning by critical thinking practice followed by a conceptual change efforts to reduce misconceptions on acid-base learn. The research design using one-group pretest-posttest design with students of SMAN 2 Ngawi as sample research. The student conception  status finding by knowing concept (TK), not knowing concept (TTK), and misconception (MK), whereas intensity of misconception be analized by CRI. Results and analysis of research data found that there is a shift in conception after inquiry learning p rocess. Based on Wilcoxon’s signed rank test, the T value of test TK, TTK, and MK is less than T table at α = 0.05 , so it was concluded that inquiry learning increase TK and decrease TTK and MK. The influence of inquiry learning for understanding the influence was strengthened by the results of the t test tests before and after understanding the concept of inquiry learning that indicate a significant difference.  t-test results on tests of critical thinking before and after the inquiry learning also showed a significant difference. Inquiry learning can not reduce all of misconceptions. Reduction step again is with conceptual change. Based on Wilcoxon’s signed rank test was concluded that conceptual change learning can reduce misconception significantlyPenelitian ini bertujuan mempelajari pengaruh pembelajaran inkuiri terbuka disertai latihan berpikir kritis yang dilanjutkan dengan conceptual change sebagai upaya mereduksi miskonsepsi pada materi asam basa. Penelitian eksperimen semu ini menggunakan metode one group pretest-postest design dengan subyek penelitian  siswa kelas XI SMA Negeri 2 Ngawi. Profil konsepsi siswa dinyatakan dengan status tahu konsep (TK), tidak tahu konsep (TTK), dan miskonsepsi (MK), sedangkan intensitas miskonsepsi diperoleh dari hasil analisis CRI jawaban siswa.  Hasil dan analisis hasil tes pemahaman konsep menemukan bahwa terjadi pergeseran konsepsi setelah proses pembelajaran inkuiri terbuka. Berdasarkan wilcoxon’s signed rank test diperoleh T hitung untuk semua status TK, TTK, dan MK kurang dari nilai T tabel pada α = 0,05 dan n = 25, sehingga   disimpulkan bahwa pembelajaran inkuiri meningkatkan jumlah TK dan menurunkan TTK dan MK.  Pengaruh pembelajaran inkuiri terhadap pemahaman konsep serta kemampuan berpikir kritis diketahui dari uji t hasil tes pemahaman konsep serta tes berpikir kritis sebelum dan setelah pembelajaran. Hasil uji t pada α = 0,05 menunjukkan adanya perbedaan signifikan pemahaman konsep serta kemampuan berpikir kritis antara sebelum dan setelah pembelajaran inkuiri. Miskonsepsi yang masih tersisa setelah pembelajaran inkuiri direduksi kembali dengan strategi   conceptual change. Berdasarkan wilcoxon’s signed rangk test disimpulkan bahwa pembelajaran conceptual change dapat mereduksi miskonsepsi secara signifikan.

AIM: To assess the effectiveness of core vitrectomy-phacoemulsification-intraocular lens (IOL) implantation-capsulo-hyaloidotomy in treating phakic eye at least 1mo after the onset of malignant glaucoma. METHODS: A retrospective analysis were performed on malignant glaucoma patients treated in Zhongshan Ophthalmic Center between 2016 and 2018. Demographic and clinical data were described. The preoperative and postoperative visual acuity (VA), intraocular pressure (IOP), number of IOP-lowering medications used, and anterior chamber depth (ACD) of the case series were compared by Wilcoxon signed-rank test. RESULTS: Thirteen phakic eyes with long time intervals between onset and surgery were identified in this case series. Core vitrectomy-phacoemulsification-IOL implantation-capsulo-hyaloidotomy reduced the IOP (P=0.046) and the number of IOP-lowering medications used (P=0.004), deepened the ACD (P=0.005). Complete success was achieved in 38.5% of the eyes, and anatomical success was achieved in 100% of the eyes without any recurrence. The only postoperative complication observed is corneal endothelial decompensation. It occurred in two cases. CONCLUSION: Core vitrectomy-phacoemulsification-IOL implantation-capsulo-hyaloidotomy is safe and effective for treatment of long onset phakic malignant glaucoma.
