Purpose: This study was done to develop the concept of grief focusing on the process of spousal bereavement in Korea. Methods: The Hybrid model was used for analysis according to the 3 phases. An extensive literature review was done for the Theoretical phase. In-depth interviews were conducted with 15 participants whose spouses died within the past 3 years in the Field phase. In the Final analytic phase, the results in the Theoretical and the Field phases were compared, analyzed, and integrated according to the process of grief. Results: The antecedent of the concept of spousal grief was spousal death. The dimensions of grief were classified to inner dimensions related to oneself, relational dimensions related to family and others, and existential dimensions related to the meaning of being. The attributes of grief were physical suffering, decline of cognitive ability, heartbreaking sorrow, expectations and conflicts of a new life, social stigma, dependence on or resentment towards God, etc. The empirical referent of grief was physical, psychological, social, and spiritual health status. The grieving progressed through 3 phases-shock-emancipation, suffering, and integration. Conclusion: Nurses should recognize the importance of their unique position as supporters for grievers, and try to assess individual characteristics and to provide tailored nursing interventions.

Along with the development of culture, dress of the Chinese people has also evolved over the last several thousand years, transcending its original functions of covering and protecting the body. As a result it has risen to become a complicated system of symbols full of intricate meanings. According to de Saussure's theory of "signs," signs are represented by the elements signified (meaning) (referent) and signifiant (sound) (exponent). "Phoenix crowns" were the headpieces most highly esteemed by women in ancient China. Actually, the name "phoenix crown" points to the fact that the headpiece is adorned with a phoenix design. The history and symbolism of the phoenix crown's use as a headpiece in Chinese weddings spans 1200 years in all, originating in the Qin Dynasty (241-210 BC) as a phoenix hairpin, evolving into the phoenix crown during the Song Dynasty (960-1276 AD), and continuing through the Ming and Qing Dynasties (1644-1911 AD), and the modem republic. It is not simply an ornamental headpiece, but instead represents the thousands of years or rich inner meaning the Chinese attribute to "dragons" and "phoenixes." This paper depicts the glorious past of phoenix crowns, using the metaphor and metonymy theories of semiology and semantics, and through the cross-verification of literature research archeological findings and reports, and old Chinese wedding photographs, in order to examine the inherent meanings of the phoenix crown in the Chinese culture.nings of the phoenix crown in the Chinese culture.

This paper proposes an integrated model of customer loyalty in the context of Internet shopping based on a review of two competing perspectives - transactional and relational views. The research model suggests that the usability and trust associated with an Internet shopping site are key determinants of customer loyalty. In this paper, factors such as promotion, ease of use/navigation, and purchase facilitation are posited as major determinants of usability. Trust, on the other hand, is assumed to be influenced by the quality of communication, social shopping service, and safety level associated with an Internet shopping site. This paper also asserts that the lack of consideration for individual differences is one of the key reasons for the inconsistent and mixed research findings in user acceptance literature. In this regard, the elaboration likelihood model (ELM) is considered to be appropriate referent theory as it may theoretically explain why a particular information technology (IT) related message has varying influences on different adopters. The research model comprising 11 hypotheses was derived from and validated through a survey involving 271 university students. The partial least square(PLS) method was used to test the suitability of the research model and its hypotheses. Overall, the results suggest that the usability and trust associated with an Internet shopping site play an important role in acquiring loyal customers. In particular, the user's Internet shopping involvement is found to moderate the relationship between trust and customer loyalty.

This survey on professionalism and job satisfaction was aimed to analyze the veterinarians' attitude toward their profession and educational needs in Korea. Two hundred and ninety nine completed questionnaires were analyzed for this study. The participants considered nontechnical competences, such as communication skills and ethical decision making skills, important as medical knowledge and skills for veterinarians. There were significant differences in veterinarians' job satisfaction among the subgroups of gender, region, specialty, employment status, and work hours. The factor analysis of adjusted Hall's professionalism scale showed 4 dimensions of Veterinarians' professionalism; belief in self-regulation, belief in public service, using the professional organization as a major referent, and autonomy. Veterinarians' professionalism was significantly related to the job satisfaction. The survey results suggest that the educational program of professionalism should be needed for the professional development of veterinary students and veterinarians.

As smartphones and tablets are drastically spreading, mobile IPTV service becomes very important emerging issue in addition to existing DMB broadcasting, and the consumption of personalized multimedia services is increasing in the mobile Internet environment. While the previous research focuses on influencing factors of the initial acceptance intention of the mobile IPTV Service, this study intends to find the factors that affect continuous use intention of the mobile IPTV service which has become one of core services in the mobile environment. The research model and the hypotheses of this study could be derived on the basis of four referent theories (that is, mobile service quality model (MOBISQUAL), post acceptance model (PAM), expectation confirmation theory (ECT) and extended technology acceptance model (ETAM)). In order to empirically test the hypotheses, the field survey was conducted for 278 respondents. Twelve ones of fifteen hypotheses were found to be statistically significantly adopted from the results of structural equation model analyses using Smart PLS 3.0. The theoretical contribution of this study is to empirically investigate the factors that affect the continuous use intention of mobile IPTV service. And the practical contribution is to provide the implementation guidelines of managing the service quality to enhance the competitive power of mobile IPTV business.

This study has two purposes. One is to systematize a number of referents and to examine the types of comparisons. The other is to examine categories of comparative standards such as inputs in equity theory. In pay comparison process, referents and inputs are very important elements. The first factor analysis is related to referents, which include 18 variables in 6 categories were subjected to factor analysis. 3 factors emerge with an eigenvalue of 1.0 or greater. Factor I, economic need, includes referents in personal worth and system referent. Factor II, market comparison, includes internal and external referents except one variable(external-peer). Between internal and external referents is not distinguished. This result is corresponded with Hills'(1980) and Hong's(1995) findings. FactorIII is named 'historical/social comparisons'. 14 inputs are subjected to the second factor analysis. 3 factors emerge with an eigenvalue of 1.0 or greater. The 5 variables loading on factor I, equity standard, are responsibility, competency, effort, outcome, and skill. FactorII, equality standard, includes age, gender, and education. FactorIII, seniority standard, includes career and company tenure. All the factors are positively associated with each other. Especially, personal worth is associated with equity standard(r=0.50466). Internal and external referents are associated with any comparative standard.

This study examined how young children understand representational relations between referents and their representational objects. Ninety-four children aged 2- to 4.5-years of age were individually tested; firstly in the scale-model tasks, and then in the scale-map tasks. Data were analyzed both by means of Chi-Square test and by a more descriptive, micro analysis. According to the results, there were significant age differences in the understanding of representational relations, regardless of the type of representational objects. In the descriptive, micro analysis, it was found that before 3 years of age, young children have a great deal of difficulties in understanding representational relations. More importantly, young children under three seemed unable to understand representational relations, especially when the similarities as well as the differences between the representational object and the referent were very high. These results suggest that teachers of very young children need to select representational materials carefully, taking into consideration children's understanding of representational relations.

Metaheuristic optimization approach has become the new framework for control synthesis. The main purposes of the control design are command (input) tracking and load (disturbance) regulating. This article proposes an optimal proportional-integral-derivative (PID) controller design for the DC motor speed control system with tracking and regulating constrained optimization by using the cuckoo search (CS), one of the most efficient population-based metaheuristic optimization techniques. The sum-squared error between the referent input and the controlled output is set as the objective function to be minimized. The rise time, the maximum overshoot, settling time and steady-state error are set as inequality constraints for tracking purpose, while the regulating time and the maximum overshoot of load regulation are set as inequality constraints for regulating purpose. Results obtained by the CS will be compared with those obtained by the conventional design method named Ziegler-Nichols (Z-N) tuning rules. From simulation results, it was found that the Z-N provides an impractical PID controller with very high gains, whereas the CS gives an optimal PID controller for DC motor speed control system satisfying the preset tracking and regulating constraints. In addition, the simulation results are confirmed by the experimental ones from the DC motor speed control system developed by analog technology.

While the term is nothing new, 'cybersecurity' still seems to be defined quite loosely and subjectively depending on context. This is problematic especially to legal writers for prosecuting cybercrimes that do not fit a particular clause/act. In fact, what is more difficult is the non-existent single 'cybersecurity law' in Malaysia, rather than the current implementation of 10-related cyber security acts. In this paper, the 10 acts are compiled into a corpus to analyse the language used in these acts via a corpus linguistics approach. A list of frequent words is firstly investigated to see whether the so-called related laws do talk about cybersecurity followed by close inspection of the concordance lines and habitually associated phrases (clusters) to explore use of these words in context. The 'compare 2 wordlist' feature is used to identify similarities or differences between the 10 Malaysian cybersecurity related laws against a corpus of cyber laws from other ASEAN countries. Findings revealed that ASEAN cyber laws refer mostly to three cybersecurity dominant themes identified in the literature: technological solutions, events, and strategies, processes, and methods, whereas Malaysian cybersecurity-related laws revolved around themes like human engagement, and referent objects (of security). Although these so-called cyber related policies and laws in Malaysia are highlighted in the National Cyber Security Agency (NACSA), their practical applications to combat cybercrimes remain uncertain.
