The paper has a two fold purpose - examine the impact of bar service operation practices (BSOP) on organizational performance (OP) and study the relationship between organizational performance and demographic variables. Based on a survey of 362 bar managers perceptions on the impact of bar service operation practices on organizational performance were assessed by 59 practices and 6 demographic variables. Bivariate test and ANOVA were employed to test the working hypothesis in the study. Results indicated that there is a positive relationship between the bar service operation practices and organizational performance. Further, the results indicate some practical and managerial implications to improve organizational overall performance.

Simplicial depth (SD) plays an important role in discriminant analysis, hypothesis testing, machine learning, and engineering computations. However, the computation of simplicial depth is hugely challenging because the exact algorithm is an NP problem with dimension d and sample size n as input arguments. The approximate algorithm for simplicial depth computation has extremely low efficiency, especially in high-dimensional cases. In this study, we design an importance sampling algorithm for the computation of simplicial depth. As an advanced Monte Carlo method, the proposed algorithm outperforms other approximate and exact algorithms in accuracy and efficiency, as shown by simulated and real data experiments. Furthermore, we illustrate the robustness of simplicial depth in regression analysis through a concrete physical data experiment.

The prevention program of the impact of HIV / AIDS is a form of handling the existence of the stigma and discrimination of PLWHA. This study aims to analyze the relationship of personal factors consisting of knowledge, perceptions and attitudes of friends about prevention the impact of HIV / AIDS with the stigma of student at the PLWHA, as well as looking for the factors that most influence student stigma against people living with HIV/AIDS. This research is an analytic observational study with a cross sectional approach with a research population of all students of the 2016 and 2017 batches classes of the University in Sukoharjo, totaling 12,457 students with a sample used was 500 students with Proportional Random Sampling. The data collection was using a self administered questionnaire and the data were analyzed using the Chi-Square test in the bivariate test while the logistic regression test was used for multivariate analysis. The results of the bivariate test showed that knowledge (p value = 0,0001), perception (p value = 0,0001), and the attitudes of friends (p value = 0,0001) with stigma of students towards PLWHA with a significant level of a = 0,05. The multivariate test found that the attitude of friends is the most influential factor on student stigma in PLWHA (OR=5,627). It is necessary to provide information to students and the scope of their friendship about HIV/AIDS, as well as HIV prevention programs to reduce stigma in PLWHA.  Keywords : personal factors, friend attitude, HIV/AIDS, stigma, PLWHA

Pain in futsal players experienced the highest incidence of 48.8% in each match. Non-pharmacological techniques are effective ways to relieve pain, including cold compresses and warm compresses. As a community nurse can apply the therapy for pre-hospital treatment. The study aims to determine the differences in the effectiveness of warm compresses and cold compresses against pain in futsal players in the Forza Futsal field in Yogyakarta. This type of research is an experimental research pre-posttest control group design. The sample in this study is a futsal player who experienced pain in the Forza Futsal Field totaling 32 respondents. The sampling technique used was consecutive sampling. The research instrument was the Bourbanais pain scale value. Analysis of research data using the Wilcoxon test and the Mann Withney test. the pre-posttest pain scale on the warm compress group was 4.00 and 2.00. The pre-posttest pain scale score of the cold compress group was 5.00 and 2.50. Bivariate test of pre-posttest pain scale score of warm compresses and cold compresses obtained p values ​​of 0,000 and 0,000. The posttest bivariate test between warm compresses and cold compresses showed a p-value of 0.683. There is the effect of warm compresses and cold compresses on pain in futsal players at Forza Futsal Field. There is no difference in the effectiveness of warm compresses and cold compresses against pain in futsal players at Forza Futsal Field.

Hypertension is one of non-communicable diseases, which is become major interest because mortality and morbidity of hypertension is the highest in the world. Slow deep breathing is non pharmacology therapy that can influence baroreflex and decrease the blood pressure. This research aimed to know the influence of slow deep breathing on blood pressure of hypertension patient in Puskesmas I Denpasar Timur. This research was pre experimental quantitative study. Design of this study was using one group pre test post test design with the intervention was slow deep breathing during 21 days, twice a day. The amount of sample in this study was 28 patients, in 35-80 years old which is chosen by simple random sampling technique. This research was conducted from� March 28th� until April 25th 2016. Univariate test was used to analyze respondent�s characteristics and bivariate test was used to analyze the difference of systolic and diastolic blood pressure to pre test and post test. The Bivariate test was using Wilcoxon because the data wasn�t� normal distributed. The result of bivariate test was significant (p-value =0,000), with level of confidence 5% so H0 was rejected. The conclusion of this study: there was influence of slow deep breathing in decrease the blood pressure of hypertension patients in Puskesmas I Denpasar Timur. Based on the result of this study, It is suggested to use slow deep breathing as non pharmacology therapy for hypertension.�Key Word: Blood Pressure, Hypertension, Slow Deep Breathing
