Ormocer has organic-inorganic compound polymers. One of advantages of ormocer is reduced polymerization shrinkage. The purpose of this study was to compare the amount of contraction shrinkage of composite resins and ormocers. Additionally, the time of each material when there is no further change of contraction shrinkage was analysed. Four brands of composite resins (P-60. Surefil, Z-250 and Denfil) and two brands of ormocers (Definite and Admira) were used. 20 seconds, 40 seconds and 60 seconds of curing times were given. Contraction shrinkage of them were measured using a linometer for 80 seconds. The effect of material and curing time to contraction shrinkage at the time of 80 seconds was analysed by two-way ANOVA. The effect of time to contraction shrinkage was analysed by one-way ANOVA and the time when there was no further change of the contraction shrinkage was analysed. The results are as follows: 1. P-60, Definite, Z-250 and Denfil had no further change of contraction shrinkage from the time of 20 seconds, and Surefil and Admira had no further change of contraction shrinkage from the time of 10 seconds. 2. Statistical analysis revealed volumetric shrinkage varied among material (p<0,05). No significant difference of contraction shrinkage among different curing times was found, and there was no effect of interaction between materials and curing times to contraction shrinkage. 3. Definite and Admira showed the statistically same contraction shrinkage with those of Z-250 and P-60. which is higher than that of Surefil and lower than that of Denfil (p<0.05).

In the present study, we investigated anti-cancer effect of snake venom activated NK cells (NK-92MI) in lung cancer cell lines. We used snake venom ($4{\mu}g/ml$) treated NK-92MI cells to co-culture with lung cancer cells. There was a further decrease in cancer cell growth up to 65% and 70% in A549 and NCI-H460 cell lines respectively, whereas 30-40% was decreased in cancer cell growth by snake venom or NK-92MI alone treatment. We further found that the expression of various apoptotic proteins such as that Bax, and cleaved caspase-3 as well as the expression of various death receptor proteins like DR3, DR4 and Fas was also further increased. Moreover, consistent with cancer cell growth inhibition, the DNA binding activity of NF-${\kappa}B$ was also further inhibited after treatment of snake venom activated NK-92MI cells. Thus, the present data showed that activated NK cells could further inhibit lung cancer cell growth.

We selected 6 plots ($100m^2$) located 2.2-3.8 km from Minamidake Crater on the north flank of Sakurajima Volcano. We conducted a field study to investigate the effects of volcanic activity on vegetation succession and surface erosion rate. The results showed that trees growing in plots further from the crater had a greater diameter at breast height (DBH), total height, and age. In addition, these plots had a greater number of woody plants and species, as well as a greater total cross-sectional area at breast height. The Fisher-Williams index of diversity (${\alpha}$) and the proportion of evergreen broad-leaved trees were higher in plots located further from the crater. Vegetation succession in these plots was not at the level of a climax forest. From 1972 to 2015, the timing for active volcano, the depth of volcanic ash layer, the dry density, and the pH of ground surface were lower for plots located further from the crater. Furthermore, the average annual sheet erosion from 1972 to 2015 was also lower for plots located further away from the crater. Overall, plots further away from the crater have a better environment for vegetation growth and a lower dry density of the volcanic ash surface layer. It is thought that lower dry density results in increased soil permeability, which impedes surface flow. In order to prevent debris-flow disasters, caused by mud and rock flow resulting from impaired soil penetrability, it is essential to promote soil development and restore penetrability by artificial vegetation restoration.

This study tests and analyzes the influence of empowering leadership on employee creativity which is mediated by psychological empowerment. Researchers conduct survey method on state-owned bank employees (ABC Bank) in Pacitan, East Java, Indonesia. Purposive sampling is selected with Likert scale as measurement. The population of this study is 166 respondents, who are permanent employees of the ABC Bank. The data analysis technique used is SPSS 24. The results of this study find that: (1) there is an influence of empowering leadership on psychological empowerment, (2) there is an influence of empowering leadership on individual creativity, (3) there is an influence of psychological empowerment on individual creativity, and (4) the influence of empowering leadership on individual creativity is mediated by psychological empowerment. This study ignores other types of leadership. Further study is needed to examine other types of leadership besides empowering leadership. The level of analysis of this study is individual, so further study could examine empowering leadership conceptualized at the group level because followers will be influenced not only by the dyadic relationship with the leader, but also by the dynamics of the members of the empowered group. This study provides theoretical enrichment from the aspect of empowering leadership, especially at the individual level. Leaders can increase employee creativity by empowering them to do their jobs. Additionally, by creating a work environment that ensures employees feel empowered psychologically.

The main objective of this study was to investigate the impact of access to finance on the different dimensions of poverty. To achieve the objectives of the study, the participants/beneficiaries of the Mudra scheme were included and sample of target respondents was extracted through multistage random sampling technique. The sample for the study was taken from the Union Territory of Jammu and Kashmir of India. The study further utilized secondary data from the government official websites and lead banks. A paired t-test was applied to test the impact of access to finance across the various dimensions of poverty by constructing the Multidimensional Poverty Index(MPI), after checking the normality of the data. MPI incorporates dimensions such as education, health, and standard of living.The finding of the study revealed that dimensions of poverty responded positively to access to finance. The study shows that larger access to finance has helped in reducing the multidimensional poverty by having moderate, but positive impact on the standard of living, health, and education, thereby improving the lives of the poor. The present study identified that the level of impact of access to finance is moderate and further explains its importance for policy implications.

Purpose: This study was conducted in order to investigate the therapeutic effect of closed reduction according to a classification in patients with nasal bone fracture. Methods: The study was conducted retrospectively on 186 patients with a mean age of 38 years (range: 7 to 80 years). All patients were diagnosed by clinical and radiologic examination, and then classified according to Hwang's classification by computed tomography. The patients were further classified by their age, gender, causes of fracture, operation timing after fracture, concurrent facial bone fracture, and complications. All patients underwent the same reduction and treatment protocol and were then followed up regularly for at least three months. Results: The cause of the fracture was slip down, and the highest prevalence was shown in the 20s. The mean operation timing after fracture was 4.1 days (range: 1 to 14 days), and it tended to be longer in the case of defected septal bone or more severe fracture. The most common concurrent facial bone fracture was orbital blow-out fracture, and zygomaticomaxillary complex and maxillary fracture occured frequently. The largest number of complications occurred in class III and IIBs patients, and the main complication was postoperative pain. Conclusion: Results of nasal bone closed reduction on the 186 patients showed that serious complications rarely occurred. Closed reduction is generally an effective treatment for nasal bone fracture. However, in the case of severe concurrent septal bone fracture or comminuted fracture with depression, open reduction should be considered. Further study with a larger number of patients and further classification is required.

Building on Technology Readiness and Acceptance Model(TRAM), the study aimed to examine how technology readiness affects consumers' perceptions of ease of use, usefulness, and risk, which in turn predict their intention to use retail service robots. Specifically, the study proposed that technology readiness motivators (optimism and innovativeness) would influence perceived ease of use and usefulness, while technology readiness inhibitors (discomfort and insecurity) would affect perceived risk. The study further examined if the perception factors (ease of use, usefulness, and risk) contribute to intention to use retail service robots. A survey method was used with data collected from Korean consumers. The final sample size was 418. The data was analyzed using structural equation modeling. Findings of the study revealed that technology readiness motivators positively affected perceived ease of use and usefulness while innovativeness had no impact on usefulness. All the inhibitors increased perceived risk. Lastly, as hypothesized, perceptions of ease of use, usefulness, and risk predicted intention to use retail service robots. This study extended the retail technology literature by applying and validating TRAM to the context of consumer acceptance of retail service robots. The study further helped marketers and retailers by highlighting the importance of technology readiness in improving consumer perceptions and responses towards retail service robots.

Objectives: We carried out an observational study of the effects of Nei Guan (P6) and Gong Sun (SP4) acupuncture for the treatment of CINV, preparing for further randomized controlled trial study. This is a case series to explore the changes in the incidence of CINV by acupuncture. Methods: Patients reported a Rhodex index indicating the severity of nausea and vomiting and loss of appetite, before acupuncture, after acupuncture and 1-week follow-up examination. Twelve patients with CINV participated in this study. We included patients receiving chemotherapeutic agents that might induce moderate or severe nausea and vomiting. We conducted 5 treatment sessions with P6 and SP4 acupuncture over the course of 5 days. Results: The median Rhodex score were decreased in 5 patients over time, while we observed loss of appetite of 6 patients were improved over time. During the study, the mean of Rhodex of total patients revealed a decrease of Day 1, Day 7, Day 14; 0.74, 0.68, 0.38, respectively, while the mean of loss of appetite showed a decrease of Day 1, Day 7, Day 14; 5.25, 4.08, 4.00, respectively. Conclusions: The study gives a preliminary data that manual acupuncture of P6 and SP4 may reduce the severity of CINV and loss of appetite, and justifies further study.

Purpose. The current study was aimed to investigate the transformational experience of a female student nurse living with type 1 diabetes. Methods. A case study of a 24-year-old diabetes patient was conducted, with interviews concerning the evolving process she had lived through during the period from her later high school years to her graduation from nursing college. Results. Followings were identified as 5-transformation process: With her diabetes-related limitation, the participant experienced 'conflict involving choosing a college and major'. The participant tried to be in charge of managing her diabetes and stepped forward to 'adaptation to college life as a new environment', and she learned more about the process of 'evolving awareness of caring' and developed herself further through the process of 'integration of the nurse identity into self-identity', and finally through the process of 'progression and preparation for getting a job' she achieved her goals, being positive about the future. Conclusions. The results of the study can provide individuals with diabetes a way of self-management and help the patients and their families in diabetes education. Further research will be needed to refine the results of this study and to learn more about the experiences of patients with type I diabetes in college years.
