Indonesia has a population of more than 260 million, of which, by 2020, Generation Y is predicted to account for 70% of the total. With different birth years, Generation Y is the backbone of Indonesia's product purchasing. Generation Y is interested in establishing strong relationships with specific brands on social media. They are also interested in working with companies to design a product. Most Generation Y utilizes more than one electronic device and they are also brand loyal. Therefore, this study seeks to examine the effect of social media (i.e., e-WOM, online community, and online advertising) on brand image and loyalty in Generation Y in Indonesia. The sampling method employed was purposive sampling. A total of 150 respondents in the age range of 23-30 years were involved as the sample. Using multiple regression model in data analysis, this study proved that e-WOM, not only have a positive and significant effect on the brand image, but also on brand loyalty. Furthermore, online community also positively and significantly affects brand image and brand loyalty. Likewise, online advertising has a positive and significant effect on brand image and brand loyalty. This study's findings indicated that all the proposed hypotheses were well accepted.

Purpose: This study aims to analyze and prove the effect of logistic capability and Total Quality Management practices on Micro, Small and Medium Enterprises (SME) performance directly or mediated by non-financial performance. Research design, data and methodology: This study tested the hypothesis using Hierarchical multiple regression analysis, the method of data collection in this study was using questionnaire, the sampling technique was purposive sampling technique, with SME that has been established for more than 5 years and manufacturing. The data analyzed were 180 respondents using SPSS 25. Results: The findings showed that logistic capability has direct and indirect effects on SME financial performance and has a positive effect on SME financial performance mediated by non-financial performance. While the total quality management practices have a positive effect on SME financial performance mediated by non-financial performance. Thus, companies can achieve maximum financial performance if they invest in developing employee knowledge and concerning on non-financial actions, such as employee satisfaction, innovation and proactively seeking market opportunities. Conclusions: In conclusion, one of the main factors that companies need to consider to improve financial performance is non-financial performance in mediating the effect of logistic capability and TQM practices on the financial performance of SMEs.

The purpose of this research is to see if liquidity, non-performing assets, sensitivity, and efficiency have an impact on the profitability and capital of Indonesian state-owned banks. A random sample of public banks was used in this study. The data was collected from the first quarter of 2014 to the fourth quarter of 2019. Purposive sampling was used as the sampling technique. According to the findings of this study, liquidity (LDR) had a significant positive effect on capital but had no significant effect on profitability. Productive asset quality as proxied by the ACA and NPL ratios did not affect profitability or capital. As for the sensitivity ratio, which was proxied by the ratio of NOP and IRR, there were differences in behavior. Sensitivity had no significant impact on profitability or capital, while NOP had a significant positive impact on capital but not on profitability. In terms of efficiency, both OER and FBIR had a significant effect on profitability and capital, although in different directions. OER has a significant negative impact on both profitability and capital. Fee-based income (FBIR) had a significant positive impact on capital, but it had the opposite effect on profitability.

The purpose of this study is to investigate the structural relationship between authenticity, club trust, club attitude, and club loyalty of e-sports professional clubs. To achieve the purpose of the study, data were collected from 260 e-sports fans. Sampling was performed using the convenience sampling method, and the completion of the questionnaire was made to respond with the self-administration. Among the collected data, 255 copies were used by adopting the final analysis data, excluding 5 copies of the data judged to be difficult to use. Data processing was performed by using SPSS 27.0. In order to verify the centralized validity and discriminant validity of the measurement items, a confirmatory factor analysis was performed using AMOS 23.0, and the hypothesis was verified using structural equation model analysis. The results were as follows. First, it was found that among the sub-factors of the authenticity of e-sports clubs, truth and effort had a significant effect on club trust. Second, it was found that club trust had a significant effect on club attitude. Third, it was found that club trust had a significant effect on club loyalty. Fourth, it was found that club attitude had a significant effect on club loyalty. The results of this study show that if e-sports clubs operate sincerely, fans' trust in the club increases. In addition, it can be seen that the higher the trust, the more positive the fans' attitude toward the club is, affecting the loyalty of the fans.

한정된 수질자료를 이용 오염부하 산정시 집중적으로 많은 샘플을 채취한 경우에 비해 어느 정도 차이를 갖는지를 규명하는 것은 모니터링에 따른 오염부하량 산정결과의 신뢰범위 파악뿐만 아니라 경제적인 수질 샘플 채수빈도 수립에 곡 필요할 것으로 사료된다. 그 결과를 요약하면 다음과 같다. 논에서의 강-은유출시 채수 빈도가 오염부하 산정에 미치는 영향을 파악하기 위해 9개의 강우사상에 대해 2시간 간격으로 연속 수질샘플을 실시하여 분석한 결과 전체적으로 강우-유출과정 중 T-N, T-P, SS 농도는 시간별로 증 감변동을 하였으나 유량과의 상관성은 나타나지 않았다. 수질샘플 횟수에 의한 영향은 강우-유출과정 중 5회 정도 샘플을 실시하면 많은 수의 샘플을 채수한 경우에 비해 T-N ${\pm}15.2%$, T-P는 $-20.0{\sim}26.2%$, SS는 $-28.6{\sim}35.7%$ 범위안에서 오염부하를 추정할 수 있는 것으로 나타났으며, 차이범위가 ${\pm}10%$ 내에 들어가기 위한 샘플수는 일주기 조사시 T-N, T-P의 경우는 6회, SS의 경우는 단기유출시는 4회 정도 실시하면 되고, 장기 유출시에는 11회 정도 실시하면 되는 것으로 조사되었다. 유량-유하부하량 관계식에서 ${\pm}10%$내의 차이를 보일 샘플횟수는 T-N의 경우는 6회 이상, T-P와 SS는 9회 이상 정도 실시하면 되는 것으로 조사되었다.

The main purposes of this study are to investigate the distributional characteristics of polycyclic aromatic hydrocarbons (PAH) in the vapor and particulate phases in the ambient atmosphere, and to evaluate the effect of ambient temperature on the vapor-particle partitioning during the sampling period. A total of 64 samples were collected during a period of 1995 to 1996, using a medium-volume sampler with XAD-2 adsorbents and quartz fiber filters. Analyses of PAH were carried out using HPLC with UV and Fluorescence detections. In this study, a significant seasonal variation in the distributions was observed, reflecting the effect of ambient temperature on the vapor-particle partitioning of PAH. The relationship between the vapor-particle distributions of the 3 to 5 rings PAH and ambient temperature is considered to be well described using the Langmuir adsorption concept. The estimated empirical constants for each PAH in the relationship, particularly for the more volatile compounds, were also comparable with results from other studies. However, it is still difficult to accurately estimate the initial vapor-particle distribution of PAH in the ambient air, since it is not known to what extent the trapped vapours originated from the particles laden in the filter by being volatilized or from the air samples initially present in the vapour phase. The distribution factors for volatile PAH with 3 to 4 rings appeared to be comparable with those in the literature. It should be noted, however, that these distribution factors give information only about the distribution of PAH between the two phases under a specific sampling condition, and hence may provide only semi -quantitative information on the vapor-particle distributions in the atmosphere.

디지털 제어 방식으로 구동되는 모든 교류 전동기 벡터제어시스템의 근간을 이루는 전류 측정에 관한 문제를 다룬다. 일반적인 펄스폭 변조 방식 교류 전동기 구동 시스템에서 전동기 전류에 포함된 인버터 스위칭 노이즈를 없애기 위하여 저역 통과 필터를 사용하는데 이러한 필터는 필연적으로 측정된 신호의 시간 지연을 유발하게 된다. 따라서 샘플링한 전류값에는 기본파 성분 뿐만아니라 고조파 리플 성분이 포함된다. 본 논문에서는 3상 대칭 펄스폭 변조시 기준 전압 벡터의 위치에 다른 전류 샘플링 오차를 해석적으로 구하고 이러한 샘플링 오차를 최소화하기 위한 기법을 제안한다. 제안된 지연 보상 샘플링 기법을 사용하면 정상 상태 전류 측정 오차를 최소화할 수 있고 보다 정확한 토오크 제어가 가능하게 됨을 시뮬레이션과 실험을 통해 보였다.
