This study is to examine the foreign direct investment (FDI) response to real effective exchange rate volatility in Vietnam by using the vector autoregression model. The research data are quarterly frequency data in the period from 2004:Q1 to 2019:Q2. The data on real effective exchange rate were collected from the statistics of Bruegel (Europe) and FDI data were collected from the International Financial Statistics. The quantitative study was conducted with two steps: (1) measuring exchange rate volatility by the GARCH(1,1) method; and (2) examining the impact of exchange rate volatility on FDI in the context of the global financial crisis. The estimation results show that FDI responded significantly to real exchange rate volatility with the lag of 3 periods at the 5% significance level. The FDI response increased after the exchange rate volatility with the lag of 3 periods, and the impact extended to the lag of 6 periods, and then gradually stabilized. The research findings indicate that FDI in Vietnam responds positively and significantly to exchange rate volatility with the lag of 3 periods. Simultaneously, the negative impact of the global financial crisis in 2008 with the lag of 2 periods leads to a slight decrease in FDI inflows into Vietnam.

Purpose: The purpose of this study are to understand the meaning and essential structure of clinical nurses' experiences of verbal violence and find nursing intervention for them by applying phenomenological research method. Methods: The participants in this study were seven clinical nurses with experience of verbal violence. Data collection were conducted from August 2016 through January 2017 until data saturation. Data analysis was performed through a cyclical process of data collection and analysis by applying Giorgi's phenomenological method. Results: Four categories were identified: A weapon of the mind: the shock of verbal abuse; negative emotions that shake my heart; skepticism about the value and meaning of a job; an unforgettable wound. Conclusions: The results of this study provide a deeper understanding of the pain caused by verbal violence experienced by nurses from their care recipients. These results suggest that nursing interventions for nurses with experience of verbal violence will contribute to resolving the problem.

A distributed high-speed data acquisition and monitoring system for the RF negative ion source at Huazhong University of Science and Technology (HUST) is developed, which consists of data acquisition, data forwarding and data processing. Firstly, the data acquisition modules sample physical signals at high speed and upload the sampling data with corresponding absolute-time labels over UDP, which builds the time correlation among different signals. And a special data packet format is proposed for the data upload, which is convenient for packing or parsing a fixed-length packet, especially when the span of the time labels in a packet crosses an absolute second. The data forwarding modules then receive the UDP messages and distribute their data packets to the real-time display module and the data storage modules by PUB/SUB-pattern message queue of ZeroMQ. As for the data storage, a scheme combining the file server and MySQL database is adopted to increase the storage rate and facilitate the data query. The test results show that the loss rate of the data packets is within the range of 0-5% and the storage rate is higher than 20 Mbps, both acceptable for the HUST RF negative ion source.

A total of 4,752 monthly lactation records of Friesian cows during the period from 2000 to 2005 were used to estimate genetic parameters and to determine the effect of udder health on milk production traits. Three milk production traits were studied: 305-day milk yield (305-dMY), 305-day fat yield (305-dFY) and 305-day protein yield (305-dPY). Four udder health traits were studied: somatic cell count (SCC), mastitis (MAST), udder health status (UDHS) with 10 categories and udder quarter infection (UDQI) with 7 categories. Mixed model least square analysis was used to estimate the fixed effects of month and year of calving and parity (P) on different studied traits. Sire and dam within sire were included in the model as random effects. Data were analyzed using Multi-trait Derivative Free Restricted Maximum Likelihood methodology (MTDFREML) to estimate genetic parameters. Unadjusted means of 305-dMY, 305-dFY, 305-dPY and SCC were 3,936, 121, 90 kg and 453,000 cells/ml, respectively. Increasing SCC from 300,000 to 2,000,000 cells/ml increased UDQI from 5.51 to 23.2%. Losses in monthly and lactationally milk yields per cow ranged from 17 to 93 and from 135 to 991 kg, respectively. The corresponding losses in monthly and lactationally milk yields return per cow at the same level of SCC ranged from 29.8 to 163 and from 236 to 1,734 Egyptian pounds, respectively. Heritability estimates of 305-dMY, 305-dFY, 305-dPY, SCC, MAST, UDHS, UDQI were 0.31${\pm}$0.4, 0.33${\pm}$0.03, 0.35${\pm}$0.05, 0.23${\pm}$0.02, 0.14${\pm}$0.02, 0.13${\pm}$0.03, and 0.09${\pm}$0.01, respectively. All milk production traits showed slightly unfavorable negative phenotypic and genetic correlations with SCC, MAST, UDHS and UDQI. There were positive and high genetic correlations between SCC and each of MAST (0.85${\pm}$0.7), UDHS (0.87${\pm}$0.10) and UDQI (0.77${\pm}$0.06) and between MAST and each of UDHS (0.91${\pm}$0.11) and UDQI (0.83${\pm}$0.07). It could be concluded that the economic losses from mastitis and high SCC are considerable. The high genetic correlation between SCC and clinical mastitis (CM) suggest that the selection for lower SCC would help to reduce or eliminate the undesirable correlated responses of clinical mastitis associated with selection for increasing milk yield. Additionally, it is recommended also that if direct information on under health traits is not available, measures of SCC can be inclusion in a selection criteria to improve the income from dairy cows.

This study is an empirical research based on data analysis obtained by surveying 655 adult men and women. The notable findings are as follow: First, overall, individuals' perception of extramarital affair is negative, but about 16.4% respondents have a positive perception of it. Second, the respondents have a more critical perception of their spouse's extramarital affairs compared to their own. Thirdly, the less critical perception of extramarital affair, the more acceptance of my extramarital relationship, the less tolerance of my spouse's extramarital relationship regardless marital status. Forth, while the less tolerance of spouse's extramarital relationship, the less openness to extramarital sex among unmarried group, the more acceptance of my own extramarital relationship, the more openness to extramarital sex among married group. Lastly, individuals' perception of extramarital relationship does not directly affect the openness to extramarital sex only among unmarried group, however, the correlation between the perception of extramarital affairs and the openness to extramarital sex is fully mediated by the effect of unacceptance of spouse's extramarital affairs. The moderating effect of marital status is proved.

After analyzing and finding the explaining factors about the "Effect of My Mom's Friend's Son (MMFS Effect)" with online-surveyed data, we introduce this concept into the conventional job search theory to develop it further. We try to estimate its effects on the hazard rate of youth pre-employment duration with some proxy variables such as his/her parents' schooling, living with parents dummy, increasing rate of consumer price index representing the burdens of parents, monthly temporary/daily workers ratio, relative ratio of quarterly 90th percentile urban household income, monthly average wage differentials between the workers of large and small firms, etc. The results confirm us the fact that so called "MMFS Effect" has been effective enough and strengthened up to recently. The conventional job search theory should be extended to be able to introduce the influencing effects of other person's success, for instance MMFS's success, on the job search behavior of youths, too.

In this study, an IoT inspection system that can be linked with a server was developed using a gas timer and ESP-01 Wi-Fi module installed on a gas valve in the home. The server environment of the gas leak IoT inspection system was installed with APM (Apache, PHP, MySQL) to collect gas pressure data by generation so that leakage checks could be performed. In order to control the gas leak IoT inspection system, the app inventory was used to manage the gas leak check value in real time. In addition, user convenience has been enhanced so that membership management, WiFi settings, and leakage check values can be checked through mobile apps. In order to manage subscribers by region, the user list was checked by logging in in in the administrator mode so that the information on whether or not the leak test was conducted and the results could be provided. In addition, when the user presses the gas leak check button, the pressure is automatically checked, and the measured value is stored in the server, and when a gas leak occurs, the leakage check is performed after alarm and repair so that it can be used if normal. In addition, in order to prevent overlapping membership, membership management can be performed based on MAC addresses.

The purpose of this study is to find out how those taking early childhood preservice teachers experience their learning through learner-centered education and the meaning given by such experiences to grasp their values. Especially, to look into experiences of learning the project approach theory studied and directly experienced, which is one of the early childhood educational approach methods, data on participatory observation, personal interviews, personal reflective journals, activity reports and ect. were collected and analyzed by the current writer, who fully participated in the class. The meaning of early childhood preservice teacher'experiences in the project approach was analyzed from the two aspects of 'my' learning activities and 'teacher's teaching activities. In the aspect of 'my' learning activities, they got indulged through purposeful practices in the process of tackling problems that originated from personal interest and wanted to share the joy of learning they'd had with others. Aware of themselves as doers of behavior and thinking, they were found to be able to focus an 'my' own learning activities based on these learning experiences of theirs. In the aspect of 'teacher's teaching activities, project theories and practices done at the same time helped them internalize the project and they learned possible changes ign the project by experiencing actual cases. To sum up, the project approach has its meaning in that it not only helps teachers learn theoretical knowledge but also have reflective thinking through their experiences as doers of learning and form practical knowledge. Accordingly, it indicates th need for intensive discussion on the project approach as a way to educate pre-teachers or current ones.

Purpose: The purpose of this study was to identify the quality of life reported by patients with multiple myeloma and secondly to identify the factors that impact the quality of life (QoL). Methods: 189 patients with multiple myeloma completed survey questionnaires. Quality of life was evaluated using European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core (EORTC QLQ-C) 30 and Multiple Myeloma (MY) 20. The data were analyzed using the t-test, ANOVA, Kruskal-Wallis test, Duncan test and the Mann-Whitney test. Results: The mean score for each subscale of EORTC QLQ-C30 was 53.35 for global health status, 73.37 for functional scale, and 31.29 for symptom scale. The mean score for each subscale of EORTC QLQ-MY20 was 60.49 for future perspective, 59.78 for body image, 20.25 for disease symptom and 24.99 for side effect of treatment. Quality of life was reported to be significantly lower among females, unemployed, dependence on a sibling for financial support for treatment, a diagnosis of anemia, having treatment, high score on Eastern Coorperative Oncology Group and high grade peripheral neuropathy. Conclusion: The results of the survey can identify characteristics impacting the QoL of patients with multiple myeloma. Developing appropriate educational strategies and nursing interventions would enhance their QoL.
