Identifying the selection criteria of wedding planners, who are the main human resource that contribute to the overall satisfaction level of a wedding's preparation, can produce important data for the wedding industry as it faces a transition period. To develop a scale for wedding planner selection criteria, preliminary items were prepared based on in-depth interviews with an experienced wedding planner group and a comprehensive review of previous studies, such as studies on selection criteria in the wedding industry and service work similar to wedding planners and wedding planner selection criteria. The preliminary items were tested for content validity using a focus group interview, comprising people in the wedding industry, and were refined accordingly. Then, the definitive quantitative questionnaire items were developed after conducting a preliminary survey. The main survey for this study was conducted using the responses of 295 consumers taking an Internet questionnaire. Exploratory factor analysis, Cronbach's alpha, and confirmatory factor analysis were adopted to develop the scale, which was tested for convergent validity and discriminant validity. This study is academically significant in that it developed a selection criteria scale tailored to wedding planners to address an area that has not been covered in previous studies. It is recommended that future studies conduct empirical analyses using the selection criteria developed in this study to compare influential variables that could affect behavior intention.

Objectives: The purpose of the study was to investigate the regional distribution and working environment of clinical dental hygienists in Korea. Methods: From 2015 to October 2016, a questionnaire was completed by 5,708 participants and the data were analyzed. Results: The region with the largest increase in clinical dental hygienist employees compared to graduates is Seoul. More than 50.0% of clinical dental hygienists working for less than 1.8 million won in the payroll period of 4-6 years were working in the Gwangju Jeonnam, Jeonbuk, and Gangwon regions. In addition, incentives and bonuses were rarely provided by localities and agencies. Although 43.4% provided both parental leave and maternity leave. Conclusions: In order to solve the fundamental problem of inter-regional movement and employee turnover rate of clinical dental hygienists, as well as address the regional imbalance in labor supply and demand, efforts should be made for institutional improvement to strengthen management and implementation.

Closed-circuit television (CCTV) technology continuously captures and stores video streams. Users are typically required by policy to store all the captured video for a certain period. Accordingly, increasing the number of CCTV operation cycles and photographing positions expands the amount of data to be stored. However, expanding the available storage space for video data incurs increased costs. In recent years, this problem has been addressed with cloud storage solutions, which enable multiple users and devices to access and store data simultaneously. However, because of the large amount of data to be stored, a vast storage space is required. Consequently, cloud storage administrators need a way to store data more efficiently. To save storage space, deduplication technology has been proposed to prevent duplicate storage of the same data. However, because cloud storage is hosted on remote servers, data encryption technology must be applied to address data exposure issues. Although deduplication techniques for encrypted data have been studied, there have been various security vulnerabilities. We attempted to solve this problem by addressing various issues such as poison attacks, property forgery, and ownership management while removing the redundant data and handling the data more securely.

With the rapid evolution of communication technology, it became possible to overcome the spatial and temporal limitations faced by humans to some extent. Furthermore, the quality of personal life was revolutionized with the emergence of the personal communication device commonly known as the smart phone. In terms of defense networks, however, due to restrictions from the military and security perspectives, the use of smart phones has been prohibited and controlled in the army; thus, they are not being used for any defense strategy purposes as yet. Despite the current consideration of smart phones for military communication, due to the difficulties of network configuration and the high cost of the necessary communication devices, the main tools of communication between soldiers are limited to the use of flag, voice or hand signals, which are all very primitive. Although these primitive tools can be very effective in certain cases, they cannot overcome temporal and spatial limitations. Likewise, depending on the level of the communication skills of each individual, communication efficiency can vary significantly. As the term of military service continues to be shortened, however, types of communication of varying efficiency depending on the levels of skills of each individual newly added to the military is not desirable at all. To address this problem, it is essential to prepare an intuitive network configuration that facilitates use by soldiers in a short period of time by easily configuring the strategy network at a low cost while maintaining its security. Therefore, in this article, the author proposes a Zigbee-based local strategic network by using Opnet and performs a simulation accordingly.

Adverse drug reactions (ADRs) constitute key factors in determining successful medication therapy in clinical situations. Integrative analysis of electronic medical record (EMR) data and use of proper analytical tools are requisite to conduct retrospective surveillance of clinical decisions on medications. Thus, we suggest that electronic medical recording and human genetic databases are considered together in future directions of pharmacovigilance. We analyzed EMR-based ADR studies indexed on PubMed during the period from 2005 to 2017 and retrospectively acquired 1161 (29.6%) articles describing drug-induced adverse reactions (e.g., liver, kidney, nervous system, immune system, and inflammatory responses). Of them, only 102 (8.79%) articles contained useful information to detect or predict ADRs in the context of clinical medication alerts. Since insufficiency of EMR datasets and their improper analyses may provide false warnings on clinical decision, efforts should be made to overcome possible problems on data-mining, analysis, statistics, and standardization. Thus, we address the characteristics and limitations on retrospective EMR database studies in hospital settings. Since gene expression and genetic variations among individuals impact ADRs, pharmacokinetics, and pharmacodynamics, appropriate paths for pharmacovigilance may be optimized using suitable databases available in public domain (e.g., genome-wide association studies (GWAS), non-coding RNAs, microRNAs, proteomics, and genetic variations), novel targets, and biomarkers. These efforts with new validated biomarker analyses would be of help to repurpose clinical and translational research infrastructure and ultimately future personalized therapy considering ADRs.

Modular construction is an emerging technology to accommodate the increasing restrictions in terms of construction period, energy efficiency and environmental impacts, since each structural module is prefabricated offsite beforehand and assembled onsite using industrialized techniques. However, some innate structural drawbacks of this innovative method are also distinct, such as connection tying inaccessibility, column instability and system robustness. This study aims to explore the theoretical and numerical stability analysis of a tenon-connected square hollow section (SHS) steel column to address the tying and stability issue in modular construction. Due to the excellent performance of composite structures in fire resistance and buckling prevention, concrete-filled steel tube (CFST) columns are also taken into account in the analysis to evaluate the feasibility of adopting composite sections in modular buildings. Characteristic equations with three variables, i.e., the length ratio, the bending stiffness ratio and the rotational stiffness ratio, are generated from the fourth-order governing differential equations. The rotational stiffness ratio is recognized as the most significant factor, with interval analysis conducted for its mechanical significance and domain. Numerical analysis using ABAQUS is conducted for validation of characteristic equations. Recommendations and instructions in predicting the buckling performance of both SHS and CFST columns are then proposed.

Microfinance is seen as a tool for poverty elimination by providing various services characterized as financial and non-financial to minority groups in the society to be included in the mainstream financial system. This paper seeks to examine the effect of microfinance institutions' (MFIs) financial and non-financial services on women's entrepreneurship and empowerment in Jordan as a developing country. To gain a deeper understanding of the effectiveness of microfinance services, the study is undertaken to address the question of what kinds of services are available and whether the MFI services are in line with the actual needs of women entrepreneurs to improve their performance. Hence, a qualitative approach was adopted in this study using semi-structured interview questions to collect data from twenty-four women entrepreneurs in Jordan. The results showed that, as regards financial services, the most important needs of women entrepreneurs include providing adequate financing with necessary financial facilities such as reducing interest, reducing monthly installments, and extending the grace period, while non-financial services should include holding specialized courses, accessing a counseling center, providing incentives and psychological support, marketing support, and monitoring and evaluation. This study concluded that factors associated with MFI play a crucial role to uplift women entrepreneurs and eliminate gender inequality.

The 'One Belt One Road (OBOR)' initiative, which was promulgated as part of the enlargement policy along with the advent of Xi Jinping in 2013, is a policy to expand China's political and economic power externally through linkages with neighboring countries. China's overseas port investment plays an important role in the promotion of the 'OBOR' policy from the coast of China through maritime transportation routes from S.E Asia to Mediterranean and Europe. Since China's overseas port investment has been made from several factors such as political, economic, and military motives, it differs in purpose and character from investments made by private companies, such as Global Port Operators(GTO) which consider profitability first. This study aims to address future prospects and implications by analyzing the geopolitics of China's overseas port investment under the 'One Belt One Road' initiative. According to the results, China's overseas port investment is dominated by state-owned enterprises and political and security factors are more important than profitability. China's overseas port investment has been on a large scale in a short period of time, and China has faced with various problems both domestically and internationally. such as debt default, environmental problems, subordination problems from recipient countries and political and military confrontation with great countries such as United States, Japan and India etc.

Objectives: The purpose of this study is to examine the process of how a parent-child relationship affects an impaired objective self, emotional regulation difficulties, and, consequently, interpersonal problems. Methods: To carry out this study, a total of 467 married women were surveyed on their parent-child relationship, impaired objective self, and emotional regulation difficulties. The resulting data was interpreted using descriptive statistics analysis, correlation analysis, and structural equation models analysis. Results: First, the parent-child relationship shows negative correlations with an impaired objective self, emotional regulation difficulties, and interpersonal problems. In addition, an impaired objective self, emotional regulation difficulties, and interpersonal problems show positive correlations with one another. Second, an impaired objective self and emotional regulation difficulties mediate the parent-child relationship and intrapersonal problems consecutively. Conclusions: This indicates that efforts to mitigate an impaired objective self and to intervene in difficulties in emotional regulation can help address intrapersonal difficulties. Finally, this paper examines how this study affects the ongoing discussion on this matter and its implications for future studies.

According to the double-phase cluster-head election method (DCE), the final cluster heads (CHs) sometimes are located at the edge of cluster. They have a long distance from the base station (BS). Sensor data is directly transmitted to BS by CHs. This makes some nodes consume much energy for transmitting data and die earlier. To address this problem, energy efficient multi-hop cluster-head election strategy (EEMCE) is proposed in this paper. To avoid taking these nodes far from BS as CH, this strategy first introduces the distance from the sensor nodes to the BS into the tentative CH election. Subsequently, in the same cluster, the energy of tentative CH is compared with those of other nodes, and then the node that has more energy than the tentative CH and being nearest the tentative CH are taken as the final CH. Lastly, if the CH is located at the periphery of the network, the multi-hop method will be employed to reduce the energy that is consumed by CHs. The simulation results suggest that the proposed method exhibits higher energy efficiency, longer stability period and better scalability than other protocols.
