In this paper, we consider a framework of compressed sensing over finite fields. One measurement sample is obtained by an inner product of a row of a sensing matrix and a sparse signal vector. A recovery algorithm proposed in this study for sparse signals based probabilistic decoding is used to find a solution of compressed sensing. Until now compressed sensing theory has dealt with real-valued or complex-valued systems, but for the processing of the original real or complex signals, the loss of the information occurs from the discretization. The motivation of this work can be found in efforts to solve inverse problems for discrete signals. The framework proposed in this paper uses a parity-check matrix of low-density parity-check (LDPC) codes developed in coding theory as a sensing matrix. We develop a stochastic algorithm to reconstruct sparse signals over finite field. Unlike LDPC decoding, which is published in existing coding theory, we design an iterative algorithm using probability distribution of sparse signals. Through the proposed recovery algorithm, we achieve better reconstruction performance as the size of finite fields increases. Since the sensing matrix of compressed sensing shows good performance even in the low density matrix such as the parity-check matrix, it is expected to be actively used in applications considering discrete signals.

This study considers the value of English-language films as material for learning a foreign tongue using posh discourse. In daily life, when we decline an invitation or convey unpleasant information to a listener, we use polite expressions; we are careful with our words. English language learners need to learn polite expressions in order to interact peacefully with others; doing so can minimize conflict, which is inherent in social relationships. This study uses the British drama Downton Abbey, which is about aristocracy. This study analyzes the posh discourse used in Downton Abbey and insists that students need to learn it explicitly. It is important to learn the polite expressions of this authentic drama in a real classroom. This study suggests that students work in groups to create a short video, and to try to understand the characters' personalities. Movies, TV dramas, and sitcoms provide great content that shows the various functions of the language that students want to learn. As a source of learning material, film can help improve students' motivation and interest in learning a foreign language.

This study was conducted to determine factors affecting professionalism of community health practitioners (CHPs). The participants in this study were 153 community health practitioners working in G province with structured self-report questionnaires from 20 August to 25 September 2017. Data were analyzed by descriptive statistics, t-test, ANONA, Scheffe's test, Pearson's correlation coefficients and stepwise multiple regression using the SPSS 20.0 program. There were statistically significant differences according to income (F=6.951, p<.001), work experience (F=5.245, p=0.002) and motivation for choosing a community health practitioner (F=3.676, p=0.004). The highest related factors were job satisfaction (${\beta}=0.320$, p<0.001), individual disposition (${\beta}=0.291$, p<0.001), income (${\beta}=0.283$, p<0.001) and job continuance (${\beta}=0.176$, p=0.009). These variables explained 49.6% of the total variance in professionalism. These findings suggest that it is necessary to develop a convergence program and policy support at the individual and organizational level to strengthen the professionalism of community health practitioners.

North Korea's demand for infrastructure construction and maintenance is growing rapidly. On the other hand, the number of skilled workers is insufficient. Therefore, through a survey of North Korean defectors, this study analyzed the status of construction technology and the difficulties of construction workers. In addition, an attempt was made to derive an appropriate education and training program process and operation plan. As a result of the survey, the reason for the low technical level of construction workers was the lack of skills, lack of motivation to work, and the lack of training and management systems. The appropriate education and training period was 56% of the total response within one year and 36% within six months. Based on the results of this survey, the period of education and training for the rapid training of construction technical personnel in North Korea was adopted as one year. Moreover, compared to the NCS standard in South Korea, appropriate training hours were suggested, excluding training courses, such as planning and design, construction management that require specialized knowledge. Finally, the curriculum corresponding to the education and training courses and the standards for facility names and required areas for facility operation were suggested.

Purpose - Goal setting is effective in any domain in which an individual or group has some control over the outcomes. It applies not only to work tasks but also to sports and health, and in various other settings. Its success depends on considering the mediators and moderators determining its efficacy and applicability. This study investigates the individual factors influencing academic goal attainability. Unlike previous studies, we focused on the effect of the relationships between individual traits (passion, tenacity, self-control) and specific motivation (vision, self-efficacy, implementation intentions) with academic goal attainability, rather than the effects of the relationship between commitment and the goal shielding mechanism with goal attainability. Research design, data, and methodology - Data collected through questionnaires were analyzed by the SPSS program. A total of 293 school students, who participated in the TOEIC program, participated in the survey. Slightly more than half were female (male: n=145 vs. female: n=148). We verified nine hypotheses through various statistical methods (reliability analysis, exploratory factor analysis, confirmatory factor analysis, structural equation model for the hypothesis test, bootstrapping test for the mediation test). Results - Data was analyzed in three phases. The first phase involved measurement analysis (i.e., item purification and factor structure confirmation), involving the scales of the three variables of individual traits, three mechanism variables, and goal attainability. The second phase involved estimating the proposed structural relationships among the key constructs (see Figure 1), using the results to test H1 to H9. The final phase involved examining the mediating effects of the three variables (vision, implementation intention, and self-efficacy). The research model shows that the independent variable passion has a significant result with both the mediators-vision and self-efficacy. Further, vision and self-efficacy significantly affect goal attainability. The second variable, self-control, shows a significant effect when mediated by implementation intentions, but the direct relationship between implementation intension and goal attainability shows an insignificant result. However, when further mediated by self-efficacy, it showed a significant effect between self-efficacy and goal attainability. Similarly, the third variable, tenacity, shows an insignificant result when mediated by vision. In contrast, the mediator self-efficacy shows a positive effect between tenacity and goal attainability. Conclusions - This study shows how these individual traits, when mediated with the appropriate motivational factors, resulted significantly in the attainability of academic goals. We may identify several theoretical and practical contributions. Theoretically, we developed a step further in the research into consumer goals and related studies. Future research could examine the effects of different learning goal types and their combinations with performance goals (e.g., learning goals first, then performance goals), different types of goal framing (approach success vs. avoid failure), the relation between goals and cognition (which, by implication, entails all of cognitive psychology), goal hierarchies, and macro goal studies with organizations of different sizes. More studies on the relationship between conscious and subconscious goals would also be valuable.

Purpose - The Service Level Agreement which has been used in the IT information communication industry to maintain the level of service supplied by a vendor has been adopted in the service industry surrounding the airliners and airports. Considering that service quality is dependent on attitude of employees who are responsible to provide service, it is very important to understand what kinds of effects SLA(service level agreement) has on the attitude when SLA is applied to the service industry. SLA is an agreement between management authority and service providing contractor to make sure that certain level of service quality should be provided. For employees whose responsibilities are providing the service, SLA has both positive effects and negative effects. Negative side is that employees have to follow many irrigating complicated rules. On the other hand, the attribute of rules is that once one is become accustomed to them one may feel comfortable doing repeated same kinds of works, which is positive side for the workers. Research design, data, and methodology - We analyzed whether the SLA has moderating effects while service providers' job environment of outsourcing companies affects job satisfaction. Especially in the service industry, job satisfaction has great effects on productivity and efficiency. Results - The study results show the following. First, SLA has moderating effects while task performance environment affects treatment satisfaction. Second, SLA has moderating effects while task motivation environment affects treatment satisfaction. Third, SLA has moderating effects while physical work environment satisfaction affects treatment satisfaction. Fourth, on the other hand, the difficulties caused by SLA have moderating effects while the relationship among employees affects job dissatisfaction, which is negative side of SLA. From these results, we can tell that SLA has more positive moderating effects on treatment satisfaction on the whole. which results can be used to justify applying SLA to the service industry. Conclusions - In this study we analyzed the effects of SLA which have become more important in service industry nowadays on service providing employees. For managing side, the positive effects of SLA have to be emphasized while the negative effects should be avoided or minimized.

The extant entrepreneurship research has emphasized the development of businesses by recognizing and exploiting new opportunities rather than the development of people in organizations. To remedy this issue, scholars recently suggested the concept of humane entrepreneurship where the traditional view on entrepreneurship is enhanced by the human-centered logic. However, more scholarly work is needed to develop the concept of humane entrepreneurship as a new perspective of the entrepreneurship research domain. In this article, we attempt to enhance the research on humane entrepreneurship by suggesting its theoretical foundations and identifying the underlying dimensions of humane entrepreneurship with empirical data. This study suggests the five disciplines in management studies as theoretical foundations of humane entrepreneurship: strategic entrepreneurship, stakeholder theory, transformational leadership, motivation theory, and humanistic management. Also, we developed the measurement of humane entrepreneurship and tested its reliability and validity by collecting data from 19 countries. The results showed that the concept of humane entrepreneurship is composed of two dimensions, humane and enterprise cycles. Finally, this study provides further research agenda in the domain of humane entrepreneurship research.

Background: Cigarette smoking is one of the leading causes of death in the world. Tobacco consumption has grave negative consequences for health so that it is important to understand the reasons and motivations towards cigarette smoking and barriers against quitting smoking among the young generation for developing effective policies to control this widespread problem. Materials and Methods: This cross-sectional survey was carried out at the Faculty of Medicine, Rabigh, King Abdulaziz University, Jeddah, Saudi Arabia. A total of 438 young smokers participated from the University and the general population. Data were collected through anonymous, self-administered questionnaires in the Arabic language that contained questions about the reasons and motivations towards cigarette smoking and barriers against quitting smoking. The questionnaire also contained several questions regarding knowledge and attitude of the participants towards cigarette smoking. The data was analyzed on SPSS-16. Results: The mean age of the respondents was $22.9{\pm}3.48$, out of 438 subjects 87 (19.9%) were married, and 351 (80.1%) were unmarried, and 331 (75.6%) belonged to urban areas while 107 (24.5%) were from the rural areas. Responding to a question about a number of cigarettes smoked per day, 31% answered 11-20, 29% answered 21-30, and 25% answered 1-10. Questioned about smokers in the family, 34.5% responded more than one, with 19% for brother and 13% for father. About the reasons for not quitting smoking, 26% described lack of willpower, 25% had no reason, 22% said that people around me smoke, and 15.3% responded stress at home/work. The major motivation for smokers was smoker friends (42%), for 33.8% others, for 12% father/brother and 7.8% media. Conclusions: There are several avoidable and preventable reasons and barriers against quitting smoking. However, knowledge and attitude about smoking were good, and the majority of the smokers were well aware of the associated hazards. Therefore, there is a need to search out ways and means to help them to quit this addiction.
