Situmorang, Gerhard Reinaldi,Umbas, Rainy,Mochtar, Chaidir A.,Santoso, Rachmat Budi Asian Pacific Journal of Cancer Prevention 2012 Asian Pacific journal of cancer prevention Vol.13 No.9

Diagnostic and therapeutic strategies of prostate cancer may largely influenced by patients' age at presentation. This study is aimed to evaluate the characteristics, diagnostic and treatment strategies in prostate cancer patients in our centres. A cross-sectional analytic study of prostate cancer data in two main referral cancer centres, Cipto Mangunkusumo General Hospital and Dharmais National Cancer Centre from 1995-2010, was therefore performed. Patients were divided into 2 sub-populations; below 60 years (younger patients) and 75 years old and above (older patients). PSA levels, diagnostic modalities, Gleason score and therapeutic options were analysed for both and compared using bivariate analysis. 152 patients were <60 years and 210 were ${\geq}75$ years. There was no statistical difference in mean PSA level (797.9ng/mL vs 345.3 ng/mL, respectively; p>0.05) and diagnosis was made by biopsy in majority of patients in both groups (68.2% and 71.6% in younger and older groups respectively). Most presented with an advanced disease stage (65.1% and 66.0%, respectively) and there was no statistically significant difference in mean Gleason scores f (8.1 vs 7.7; p>0.05). Primary androgen deprivation therapy (PADT) was the main treatment for overall patients (48.0% and 50.7%, respectively). Radiotherapy and radical prostatectomy are the main therapeutic modalities for younger patients with local and locally advanced disease (39.6% and 35.4% respectively), while the majority of older patients with the same disease stage were treated with radiotherapy and PADT (45.8% and 39.0% respectively). Differences observed in treatment modalities were statistically significant (p<0.0003). We conclude that there is no difference in disease clinical aggressiveness of the two groups but significant differences were observed in therapeutic strategies utilised with younger and older patients.

Tumpal Pangihutan SITUMORANG,Farida INDRIANI,Rintar Agus SIMATUPANG,Harry SOESANTO 한국유통과학회 2021 The Journal of Asian Finance, Economics and Busine Vol.8 No.4

The purpose of this study was to examine the moderating effect of attitude toward green brand on green brand positioning and repurchase intention of environmentally friendly products, product knowledge on attitude toward green brand and the effect of green product knowledge on green repurchase intention. This study uses a structural equation approach with a sample size of 175 and uses an eight-point Likert scale. The data collection technique used purposive sampling. The criteria for respondents are to use environmentally friendly cosmetic products and the respondents live in Central Java and have consumed more than two times. Online sampling using google form. Data were analyzed using statistical software AMOS 22. The results showed that green brand positioning has a significant effect on repurchase intention. Attitude toward green brand has a positive effect in mediating the relationship between green brand positioning and repurchase intention. Similarly, green brand knowledge has a positive effect on attitudes, although green knowledge has no positive effect on repurchase intention. Product positioning in the minds of consumers is important in shaping attitudes. It is important for companies to continue to develop environmentally friendly products so that product positioning can be distinguished from competitors’ products.

This study aims to analyze the relationship of e-HRM implementation to employee performance both directly and indirectly through the intervening of the Human Resource service Quality variable, both practically and theoretically. This study uses variance-based structural equation modeling (SEM) techniques with partial least square (PLS) statistical testing tools to test the direct relationship of e-HRM and the performance and relationship moderated by Human Resources service quality tested on 200 civil servants in five offices under the coordination of the Government of the South Sulawesi Province of Indonesia. The data collection model in this study uses an online survey. The data analysis stages through the explanatory concept consist of, first, the interpretation of the distribution of the average frequency of respondents' answers; second, outer-loading; third, determination of the validity and reliability; fourth, the coefficient of determination test and partial test; fifth, the GoF model; sixth, validity test; and seventh, hypothesis testing. This study explores four hypotheses in a comprehensive fashion; the results of this study show that all hypotheses have positive and significant effects both through direct and intervening relationships. Among the three direct relationships, the relationship of e-HRM variables on HR Service Quality is greatest and most dominant.

The Role of Government Regulations in Enhancing Corporate Social Responsibility Disclosure and Firm Value

FAISAL, Faisal,SITUMORANG, Lilis Suryani,ACHMAD, Tarmizi,PRASTIWI, Andri Korea Distribution Science Association 2020 The Journal of Asian Finance, Economics and Busine Vol.7 No.8

This study investigates, first, whether the extent of corporate social and environmental responsibility disclosure (CSERD) differs between 2010 and 2014; second, whether government regulation affects the extent of CSERD; and, third, whether the CSERD is valued by investors. Content analysis method was used to extract 466 companies' annual reports to measure the extent of social and environmental responsibility disclosure based on the Global Reporting Initiative (GRI) checklist. Independent sample t-test and multivariate regression analysis were also conducted to test the differences of the extent of CSERD as well as determinants and consequence of CSERD. Our results show that the extent of CSERD in 2014 is 21.60 percent higher than in 2010 (13.39 percent). Government regulation has a significant effect on the extent of CSERD. This study also finds that market values positively CSER information disclosed by company. Given that government regulation has a positive impact, however, the findings of this study suggests that the extent of CSERD is still low. To enhance CSERD, government should continuously encourage companies to abide by the regulations as mandated. This study provides a more comprehensive insights of CSRED practices from an emerging country and the effect of government regulation in enhancing CSERD.

The doping of a host glass with rare-earth ions is quite interesting when investigating their wide applications in several fields, such as laser and optical fibers. In this study, the glass medium had a composition of (70 − x) P2O5– 10Bi2O3–10Na2O–10Gd2O3–xSm2O3 with x = 0, 0.05, 0.1, 0.5, 1.0, 3.0 mol% and were fabricated using melt-quenching method. The optical properties of Sm3+- doped samples with different Sm3+ concentrations were determined by measuring the absorption and luminescence spectra in the visible light region. Both the direct and the indirect bandgap energies were slightly decreased after doping with Sm3+ ions. The maximum experimental oscillator strength was 3.65 × 10–6 for the band transition 6H5/2 → 6F7/2 over glass PBNaGSm5. The Judd–Ofelt parameters were applied to evaluate the properties of glass samples. The highest emission intensity was located in the orange range with a wavelength of 597 nm under an excitation wavelength of 401 nm. An obvious decrease in the lifetime was observed at higher Sm3+ ion concentrations.
