  • Operation of LNG (Liquefied Natural Gas) plants requires an effective maintenance strategy. To this end, the long-term and short-term trend of faults, such as mechanical and electrical troubles, should be identified so as to take proactive approach for ensuring the smooth and productive operation. However, it is not an easy task to predict the fault trend in LNG plants. Many variables and unexpected conditions make it quite difficult for the facility manager to be well prepared for future faulty conditions. This paper presents a model to predict the fault trend in a LNG plant. ARIMA (Auto-Regressive Integrated Moving Average) model is combined with Wavelet Transform to enhance the prediction capability of the proposed model. Test results show the potential of the proposed model for the preventive maintenance strategy.

  • Vehicular networks are part of the next generation wireless and smart Intelligent Transportation Systems (ITS). In the future, autonomous vehicles will be an integral part of ITS and will provide safe and reliable traveling features to the users. The reliability and security of data transmission in vehicular networks has been a challenging task. To manage data transmission in vehicular networks, road networks are divided into clusters and a cluster head is selected to handle the data. The selection of cluster heads is a challenge as vehicles are mobile and their connectivity is dynamically changing. In this paper, a novel secure cluster head selection algorithm is proposed for secure and reliable data sharing. The idea is to use the secrecy rate of each vehicle in the cluster and adaptively select the most secure vehicle as the cluster head. Simulation results show that the proposed scheme improves the reliability and security of the transmission significantly.

  • Objective: We conducted a survey to understand the current state of pharmacy services and pharmacists' thoughts in the future of the community pharmacy setting. Methods: A questionnaire was distributed to 229 pharmacists and gathered from 95 respondents. Results: We asked to pharmacists about what the ideal pharmacy duty should be in the next 10 years at the community pharmacy setting in Korea. For this question, the respondents said drug counselling (19.4%), dispensing (13.8%), long-term care of chronic disease and healthcare education (12.8%), and OTC counselling (11.5%). When asked about how much time they were spending doing certain tasks in the pharmacy, the main tasks were dispensing (23.5%), counselling (17.1%), prescription review (10.1%), and OTC counselling (5.5%). When asked about what the most important duty of a pharmacist was, medication counselling (45.4%) was the most important task that they identified and the reasons for not being able to fulfill this role properly was time shortage (78.9%) followed by the lack of counselling spaces, up-to-date knowledges, and focus on financial gains over patient counselling. Conclusion: Korean pharmacists are mainly focusing on dispensing in their daily work. Their basic responsibilities can be easily mechanized over the next few years, but the social expectations of disease-prevention and public health promotion both in current and future can not be replaced by such mechanical measures. Therefore, pharmaceutical services in Korea should be developed in more diverse and professional ways.

  • Despite the number of developed theories, it still remains a difficult task for some established and emerging scholars in various academic fields to clearly articulate new theories from research studies. This paper reviews and collates the views of scholars on what a theory is and how a good theory can be developed. It explains the concept of a theory, and the different components that make up a theory. The paper discusses the different processes of theory development by emphasizing what theory is and what theory is not. This review found that scholars differ in their definition of a theory, which leads to using terms such as model, paradigm, framework, and theory interchangeably. It found the lack of theoretical constructs in a study to be one of the factors which explains why articles are rejected for publication. This paper may be of benefit to established researchers who may be struggling with theory development, and especially younger academics who are the future of scholarship in various academic fields, particularly in information science.

  • The shapes(mass) of buildings are determined by many interrelated factors, such as planning and building regulations, the size and shape of building parcels, and adjoining road conditions. Understanding the effects of the determinants on the building shapes is not a simple task because of the multiplicity and complex interrelationships of the determinants. This study developed a prototype of three dimensional computer model that can simulates the determination process of building shape using GIS and CAD techniques. A commercial block in the south of Seoul was selected for the case study. Several methods of building height control were applied, and their effects on the cityscape were evaluated. The results shows that the three dimensional computer modelling offers an effective means for evaluating the effects of planning and building regulations. The implication of the case study and future research directions were discussed.

  • Slipping during various kinds of movement often leads to potentially dangerous incidents of falling. The purpose of this paper was to review some of the research performed in the field including such topics as rating scales for balance, kinematics and kinetics of slipping, adaptation to slippery conditions, postural and balance control, and protective movement during falling. Controlling slipping and fall injuries requires a multifaceted approach. Environmental conditions (state of floor surface, tidiness, lighting, etc), work task (walking, carrying, pushing, lifting, etc), and human behavior (anticipation of hazards, adaptation to risks, risk taking, etc) must be accounted for in the assessment of slip and fall-related risks. Future directions of research must deal with modeling of basic tribophysical, biomechanical, and postural control process involved in slipping and falling.

  • Nursing's traditional concern for human well being includes concern for health promotion. Until recently textbooks of preventive medicine, public health and community health nursing have defined health prevention- the prevention of disease and health protection or maintenace, but not health promotion. Lack of clear definitions inhibit effective communication among health related disciplines. Therefore, this studys task was the analysis and definition of the concept of health promotion using Walker & Avant's concept analysis methodology. This characteristics of the concept of health promotion are 1) orientation toward well - being, 2) empowering, 3) subjectivity, 4) change and 5) expanded connecteness. Antecedent of health promotion are 1) attaining of a healthy state, 2) having purpose and will to act, 3) persistent and realistic behaviour. The consequences of health promotion are 1) prolonged life, 2) self-actualizing potential, 3) increased well-being and a high level quality of life. The future direction of health promotion research should include that identification of the differences in the definition of between health professionals and health clients and research related to nursing theory of health promotion.
