The purpose of this study is to understand the faith and life experiences of Christian seniors who hold a doctoral degree and to glean insights for the senior ministry of the church from what they propose based on their wisdom and own experience. To this end, seven participants were purposefully selected based on certain criteria and interviewed. Research findings were presented into three categories: faith, calling and life after retirement, and suggestions for the senior ministry of the church. For the research participants, the mature faith was fear of God and acknowledgement of Lordship of God, revealed through thoughts, words and actions and their agreement. The natural outcome is others may recognize such true godliness embodied in love of neighbors. The call to scholarship was a gift of God, which accompanies responsibilities, The research participants were immersed in meaningful work for the church and the next generation, following their calling even after retirement. The church's ministry for the elderly should start from recognizing resourcefulness of their life and wisdom for sanctification and growth of congregation members across all generations, aim for shaking souls of the elderly for God-pleasing life and eternal inheritance, and be supported by younger generations, online ministry and technology. To ensure that eternal goals, the fulfillment that comes from doing meaningful work, and passion to complete the race without stagnation in all aspects of piety, morality, and intelligence should become the characteristics of the lives of all elderly people, not just the research participants, such preparation should start before retirement by intervention and aid of the church.

In this paper, a reliability sampling plan under progressively type-1 interval censoring is proposed when the lifetime of products follows the Pareto distribution of second kind. We use the maximum likelihood estimator for the median life and its asymptotic distribution. The cost model is proposed and the design parameters are determined such that the given producer's and the consumer's risks are satisfied. Tables are given and the results are explained with examples.

Objective : Peripheral neuropathy is characterized by hyperalgesia, spontaneous burning pain, and allodynia. The purpose of this study was to investigate the effect of rolipram, a phosphodiesterase-4-specific inhibitor, in a segmental spinal nerve ligation model in rats. Methods : Both the L5 and L6 spinal nerves of the left side of the rats were ligated. Phosphodiesterase-4 inhibitor (rolipram) and saline (vehicle) were administered intraperitoneally. We measured mechanical allodynia using von Frey filaments and a nerve conduction study. Results : The mechanical allodynia, which began to manifest on the first day, peaked within 2 days. Multiple intraperitoneal injections of rolipram ameliorated the mechanical allodynia. Furthermore, an intraperitoneal administration of rolipram improved the development of pain behavior and nerve conduction velocity. Conclusion : This study suggests that the phosphodiesterase-4 inhibitor, rolipram, alleviates mechanical allodynia induced by segmental spinal nerve ligation in rats. This finding may have clinical implications.

The objective of this study is to develop an optimal joint cost from the perspectives of both the manufacturer and the retailer. The integrated production-inventory model with Weibull distribution deteriorating items is assumed to have a constant demand rate. A limited retailer storage space and multiple delivery per order are considered in this model. A numerical example including the sensitivity analysis is given to validate the results of the production-inventory model.

For heat-assisted magnetic recording, magnetization reversal probabilities of nano-Pt/MnSb multilayer film with perpendicular magnetic anisotropy under thermal pulse activation were investigated numerically by solving the Landau-Lifshift Gilbert Equation. Magnetic parameters of nano-Pt/MnSb multilayer were used with anisotropy energy of $3{\times}10^5$ erg/cc and saturation magnetization of 2100 G, which offer more than 10 y data stability at room temperature. Scheme of driven magnetic field and thermal pulse on writing mechanism was designed closely to real experiment. This study found that the chosen material is potential to be used as a high density magnetic storage that requires low writing field less than two-hundreds Oersted through definite heating and cooling interval. The possibility of writing data with a zero driven magnetic field also became an important result. Further study is recommended on the thickness of media and thermal pulse design as the essential parameters of the reversal magnetization.

To gain competitive advantage in a fast changing environment, the higher education institution (HEI) must continuously adjust the strategies to that environment. One important strategy is how to determine appropriate practical actions based on what students really need and want. Despite the abundance of research on service quality management, there is no universal consensus on how best to determine appropriate practical actions in HEIs. The aim of this paper is to develop an integrated model to be used to accurately acquire the most critical service attributes and determine appropriate actions that promote student satisfaction. Drawing on relevant literature, an integrated model is proposed which is based on students' perspective by integrating the fuzzy SERVQUAL, refined Kano, and Blue Ocean model. Subsequently, an empirical case study in the higher education sector is described that illustrates the value of the model in determining the most critical attributes and how to improve them.

Objective : Alcoholic neuropathy is characterized by allodynia (a discomfort evoked by normally innocuous stimuli), hyperalgesia (an exaggerated pain in response to painful stimuli) and spontaneous burning pain. The aim of the present study is to investigate the effect of rolipram, a phosphodiesterase 4 inhibitor, against alcohol-induced neuropathy in rats. Methods : Allodynia was induced by administering 35% v/v ethanol (10 g/kg; oral gavage) to Spraue-Dawley rats for 8 weeks. Rolipram and saline (vehicle) were administered intraperitoneally. Mechanical allodynia was measured by using von Frey filaments. Somatosensory evoked potential (SEP) was proposed as complementary measure to assess the integrity of nerve pathway. Results : The ethanol-induced mechanical allodynia began to manifest from 3 week, and then peaked within 1 week. Beginning from 3 week, latency significantly started to increased in control group. In rolipram treated rats, the shorter latency was sustained until 8 weeks (p<0.05). The mechanical allodynia, which began to manifest on the 3 weeks, intraperitoneal injections of rolipram sustained statistical difference until 8 weeks, the final week of the study (p<0.05). Conclusion : This study suggests that rolipram might alleviate mechanical allodynia induced by alcohol in rats, which clearly has clinical implication.

Purpose: The purpose of this study was to identify the effects of an education program on safety perception, safety control, autonomy and accountability in clinical nurses. Precedent cases related to patient safety were used in the education program. Methods: A quasi-experimental design with pretest and posttest measures was used. Participants in the study, 72 nurses in the experimental group, 71 nurses in the control group, were enrolled for 3 months. The education program was composed of the 20 precedent cases related to patient safety from home and foreign countries. Results: The major findings of this study were as follows: Safety perception (p=.000), Safety control (p=.000), attitude toward autonomy (p=.000), and attitude toward accountability (p=.000) improved after the education program. Conclusion: The findings from this study indicate that an education program using precedent cases is an efficient method to improve behavior and change attitudes towards protecting patients' safety and preventing malpractice claims against nurses.
