  • One form of complementary and alternative medicine (CAM), oriental medicine has developed differently from the western medicine under its own environment and history. Western medicine was introduced to Korea about 120 years ago. But unfortunately, there still is an indisputable lack of cooperative movement between oriental medicine & western medicine. However, the market share of CAM has grown markedly in most industrialized countries (the United States, Europe, Australia, and Asia). In these countries, alternative medicine such as acupuncture and herbal remedies was adopted as a "complementary" therapies of mainstream medicine, to calm the symptoms of terminal illness. Recently in Korea, there was a movement to cooperate oriental medicine & western medicine. However, until this time in Korea, there was a conflict between oriental medicine & western medicine. They blame each other. Such as "Other side is guilty of improper evaluation of patients, possibly suppressing effective therapies of their own side and profit-motivated". Though most western medicine practitioners criticize oriental medicine, the level of adopting alternative forms of health care by the public and by some western medicine practitioners will continue to increase. Therefore oriental medicine & western medicine share a mutual responsibility to apply evidence-based practices, to seek scientific empirical proof through planned interventions, and to increase the quality of health care.lity of health care.

  • Ginseng root has been considered to prevent neuronal degeneration associated with brain ischemia, but experimental proof in support of this speculation is limited. Moreover, few studies have compared the neuroprotective actions of ginseng ingredients with those of peptide growth factors and cytokines isf vivo. Using a gerbil forebrain ischemia model, we demonstrated that the oral administration of red ginseng powder before an ischemic insult prevents delayed neuronal death in the hippocampal CAI field and that a neuroprotective molecule within red ginseng powder is ginsenoside Rbl. The neurotrophic effect of ginsenoside Rbl, when examined in the gerbil ischemia model and in neuronal cultures was as potent as or more potent than the effects of epidermal growth factor, ciliary neurotrophic factor, erythropoietin, prosaposin, interleukin-6 and interleukin-3. Besides the protection of hippocampal CAI neurons against brain ischemia/repercussion injuries, ginsenoside Rbl was shown to prevent place navigation disability, cortical infarction and secondary thalamic degeneration in stroke-prone spontaneous hypertensive rats with permanent occlusion of the unilateral middle cerebral artery distal to the striate branches. These findings may validate the empirical use of ginseng root for the treatment of cerebrovascular diseases

  • Fraud cases that are committed by top management or people who have high positions or organization can be called character assassination crimes. The purpose of this study was to determine the effect of ethical leadership on organizational citizenship behavior and the effect of ethical leadership on job satisfaction and job satisfaction on organizational citizenship behavior. This study uses quantitative methods with SEM analysis tools partial least square (PLS) with the population of this study being all civil servants in the Kediri city government with 125 organizational members. This research instrument uses a questionnaire divided into three main parts: (1) leadership ethics as measured by 6 indicators and 12 items. (2) Organizational Citizenship Behavior (OCB) as measured by 7 dimensions and 14 items (3) job satisfaction as measured by 4 indicators and 8 items. Based on the results of the discussion of data analysis that has been carried out through data processing and proof of hypotheses, it can be concluded that an increase in ethical leadership will have an impact on increasing organizational citizenship behavior, an increase in ethical leadership variables will affect job satisfaction and that job satisfaction has no significant effect on organizational citizenship behavior.

  • This study examines whether accounting conservatism can support real earnings management by reducing accrual earnings management techniques. The net impact of conservative reporting on earnings management is also analyzed. It is assumed that moderating the role of conservative financial reporting during uncertainty can mitigate earnings management practices. For our analysis, 5354 firm-year observations for the period 2007-2020 of nonfinancial companies listed on the Pakistan Stock Exchange are applied. To measure conservatism in the non-financial sector of Pakistan, Khan and Watts' (2009) model is used to provide evidence that conservatism is a way to restrict earnings management during uncertainty. "Prospector" and "Defender" Business strategy is applied for measuring firm-level uncertainty. To measure accrual earnings management Modified Jones (1995) model and Dechow and Dichev (2002) approach and Kasznik (1999) model are applied, and for real earnings management Roychowdhury model is applied which follows three approaches to measure real earnings management i.e. cash flow manipulation, Overproduction, and discretionary expenses. The estimations support our hypothesis by providing statistically significant proof that conservative financial reporting in a developing economy like Pakistan may be used to overcome the net impact of earnings management during uncertainty. Our results provide critical and practical implications for investors, researchers, and standard setters.

  • Studies examining the interplay between brand transgression and brand forgiveness is notably sparse especially in the context of Southeast Asian banking customers. The purpose of this research is to add to the existing literature by examining the impact of brand transgression, which is represented by negative past experience image incongruence, and corporate wrongdoing on brand forgiveness among Islamic banking customers in Malaysia. The increasing surge in interest in unfavorable brand relationships has sparked concerns about its impact on brand forgiveness. As a result, this theoretical argument, which lacks empirical proof, has to be statistically tested. The current study was conducted utilizing a non-probability purposive sampling technique among clients in the Klang Valley who had poor experiences with Islamic banking services. Data analysis included descriptive statistics, exploratory factor analysis, and multiple regression on a total of 211 valid replies. The findings show that two elements of brand transgression, image inconsistency, and corporate wrongdoing, have a major impact on brand forgiveness. However, the other dimension namely negative past experience was found to be non-significant to brand forgiveness. Research implications and directions for future studies are also discussed in this paper.

  • Cloud-based architectures for precision agriculture are domain-specific controlled and require remote access to process and analyze the collected data over third-party cloud computing platforms. Due to the dynamic changes in agricultural parameters and restrictions in terms of accessing cloud platforms, developing a locally controlled and real-time configured architecture is crucial for efficient water irrigation and farmers management in agricultural fields. Thus, we present a new implementation of an independent sensor-enabled architecture using variety of wireless-based sensors to capture soil moisture level, amount of supplied water, and compute the reference evapotranspiration (ETo). Both parameters of soil moisture content and ETo values was then used to manage the amount of irrigated water in a small-scale agriculture field for 356 days. We collected around 34,200 experimental data samples to evaluate the performance of the architecture under different agriculture parameters and conditions, which have significant influence on realizing real-time monitoring of agricultural fields. In a proof of concept, we provide empirical results that show that our architecture performs favorably against the cloud-based architecture, as evaluated on collected experimental data through different statistical performance models. Experimental results demonstrate that the architecture has potential practical application in a many of farming activities, including water irrigation management and agricultural condition control.

  • The comprehensive implication in justification activity that includes the proof in the elementary school level where the logical and formative verification is hard to come has to be instructed. Therefore, this study has set the following issues. First, what is the mathematical justification type shown in the Number and Operations, and Geometry? Second, what are the errors shown by students in the justification process? In order to solve these research issues, the test was implemented on 62 third grade elementary school students in D City and analyzed the mathematical justification type. The research result could be summarized as follows. First, in solving the justification type test for the number and operations, students evenly used the empirical justification type and the analytical justification type. Second, in the geometry, the ratio of the empirical justification was shown to be higher than the analytical justification, and it had a difference from the number and operations that evenly disclosed the ratio of the empirical justification and the analytical justification. And third, as a result of analyzing the errors of students occurring during the justification process, it was shown to show in the order of the error of omitting the problem solving process, error of concept and principle, error in understanding the questions, and technical error. Therefore, it is prudent to provide substantial justification experiences to students. And, since it is difficult to correct the erroneous concept and mistaken principle once it is accepted as familiar content that it is required to find out the principle accepted in error or mistake and re-instruct to correct it.

  • The objective of this study is to investigate the volatility spillover effects among BDI, CCFI and SCFI. This paper will divide the empirical analysis section into two periods to analyze and compare the differences in volatility spillover effect between shipping freight indices before and after the outbreak of COVID-19 separately. First, in order to compare the mean spillover impact and index lead-lag correlations in BDI and CCFI indices, along with BDI and SCFI indices before and after COVID-19, the co-integration analysis and the test of Granger causality built on the VAR model were utilized. Second, the impulse response and variance decomposition are employed in this work to investigate how the shipping freight index responds to shocks experienced by itself and other freight indices in a short period. Before the COVID-19 epidemic, the results demonstrated that the BDI freight index is the Granger cause of the variable CCFI freight index. But the BDI and CCFI freight indices have no apparent lead-lag relationships after COVID-19, and this empirical result echoes the cointegration test result. After the COVID-19 epidemic, the SCFI index leads the BDI index. This study employs the VAR-BEKK-GARCH joint model to explore the volatility spillover results between dry bulk and container transport markets before and after COVID-19. The empirical results demonstrate that after COVID-19, fluctuations in the BDI index still affect the CCFI index in the maritime market. However, there is no proof of a volatility spillover relationship between the BDI and SCFI after the COVID-19 epidemic. This study will provide an insight into the volatility relationship among BDI, CCFI and SCFI before and after the the COVID-19 epidemic occurred.

  • For the development of load and resistance factor design, reliability analysis is required to calibrate resistance factors in the framework of reliability theory. The distribution of measured-to-predicted pile resistance ratio was obrained based on only the results of load tests conducted to failure for the assessment of uncertainty regarding pile resistance and used in the conventional reliability analysis. In other words, successful pile load test (piles resisted twice their design loads without failure) results were discarded, and therefore, were not reflected in the reliability analysis. In this paper, a new systematic method based on Bayesian theory is used to update reliability indices of driven steel pipe piles by adding more proof pile load test results, even not conducted to failure, to the prior distribution of pile resistance ratio. Fifty seven static pile load tests performed to failure in Korea were compiled for the construction of prior distribution of pile resistance ratio. The empirical method proposed by Meyerhof is used to calculate the predicted pile resistance. Reliability analyses were performed using the updated distribution of pile resistance ratio. The challenge of this study is that the distribution updates of pile resistance ratio are possible using the load test results even not conducted to failure, and that Bayesian updates are most effective when limited data are available for reliability analysis.

  • This study aimed to provide an empirical analysis of the effect of preventive fire administration (PVFA) and prepared fire administration (PPFA) on response fire administration (RPFA) in fire service organizations in Korea. To this end, panel data was collected from 16 metropolitan councils from the period of 2008 to 2018 and statistically analyzed using PVFA, PPFA, and RPFA. The independent variables were PVFA and PPFA, while the dependent variable was RPFA. The analysis of the current situation of the specific target for firefighting (STFF), public use facilities, proof of completion of safety families for public use facilities, and special fire inspection were sub-variables of PVFA. Fire safety education (FSE) and the mobilization for fire suppression (MFS) were sub-variables of PPFA and RPFA, respectively. In the results, STFF and FSE had a significant positive influence on the MFS. This study will contribute to the basic research regarding the investigation of the effectivity of fire service organizations in Korea.
