Human resource is considered as an important resource that enables organizations to achieve competitive advantage. As such, it is important to have engaged employees to drive the strategic objectives of the organization. The study focuses on variables that can promote employee engagement. Work-life balance and employee engagement have received attention in both academia and practice. Engaged employees are crucial in the achievement of the strategic objectives of organizations. Besides, the role of religious orientation in life and work has been gaining attention from management scholars. The paper attempts to fill the research gap by developing a conceptual model and propositions for empirical testing. Specifically, the study proposes that work-life balance is expected to act as a mediator in the relationship between religiosity and employee engagement. Furthermore, religiosity is included as a moderator since religious belief can strengthen the positive relationship between work-life balance and employee engagement. A systematic literature review was carried out. A framework and propositions for future studies have been developed. The proposed framework provides direction for scholars to empirically test the indirect relationship between work-life balance, religiosity and employee engagement. Empirical testing of the framework could provide insights into how work-life balance and religiosity promote employee engagement.

Recently, the COVID 19 pandemic has affected on our daily lives and society in many ways. Specifically, it has brought rapid changes in the working environment from office working to smart telecommuting. In addition, cloud computing technology and services not only provided ubiquitous access, but also led to a sharing of information, internal-external communication channels, telework, and innovative smart work for the business process. As a result, smart work services based on social cloud networking have spread to the public sector. However, existing academic research examining smart work merely remains to focus on the theoretical conceptualization or to deal with merely several examples of private views. Best practices of smart work services based on cloud computing technology in the public field rarely exists. Moreover, many studies have been differently measured the values of smart work for private and public sectors depending on organizational singularities. Therefore, the study aims to define new theoretical implications and to explore future business strategies and policy directions based on a technical working group's personal psychological subjectivity. The research applied Q methodology, and selected five public organizations in Korea, that they have adopted or currently plan to adopt some part of smart work services.

This paper describes an operational concept of the network based future airborne force power using a systems engineering approach. The battlefield is changing to new system of systems that command and control by the network based BM/C4ISR. Also, it is composed of various sensors and shooters in an single theater. Future threats may be characterized as unmanned moving bodies that the strategic effect is great such as UAVs, cruise missile and tactical ballistic missiles. New threats such as low altitude stealth cruise missile may also appear. The implementation of future airborne force power network systems against these future threats is required to complex and integrated approach based on systems engineering. This work developed the operational concepts of the future airborne network system, and then derived the requirements for performing missions effectively. In addition, the scheme of future airborne force power network systems is presented.

도심지 건축공사가 증가하고 있는 우리나라에서 작업공간의 부족 및 자재의 적시공급에 대한 문제는 반드시 해결해야 할 과제이다. 이 중에서도 주택건설에 있어 가장 큰 비중을 차지하고 있는 아파트 시공의 경우, 초고층화로 골조공사의 중요성과 함께 친환경적 공법과 합리적 공정개선 및 원가절감을 구현할 새로운 공법이 요구되고 있다. 본 연구에서는 국내 건설현장의 사례조사를 통해 슬래브 거푸집공사와 마감공사의 프로세스에서 불필요한 요소를 최소화하고자 공업화 자재를 활용한 (골조-마감공사)통합공법을 제시한다 가치흐름분석기법(Value Stream Mapping)을 활용하여 기존 프로세스에서의 비 가치 창출작업을 가치창출작업에 통합시키거나 제거하여 슬래브 공사 내에서 공기 및 투입인력의 절감 가능성을 확인하고, 공기단축과 원가절감 효과를 측정하였다. 이와 같이 공업화 자재의 활용으로 현장작업에 따른 변이를 최소화하여 공정의 안정성 및 공정계획의 신뢰성을 확보 등 공정의 합리화를 구현하고자 한다.

Background: With recent progress in health science administration, a huge amount of data has been collected from thousands of subjects. Statistical and computational techniques are very necessary to understand such data and to make valid scientific conclusions. The purpose of this paper was to develop a statistical probability model and to predict future survival times for male breast cancer patients who were diagnosed in the USA during 1973-2009. Materials and Methods: A random sample of 500 male patients was selected from the Surveillance Epidemiology and End Results (SEER) database. The survival times for the male patients were used to derive the statistical probability model. To measure the goodness of fit tests, the model building criterions: Akaike Information Criteria (AIC), Bayesian Information Criteria (BIC), and Deviance Information Criteria (DIC) were employed. A novel Bayesian method was used to derive the posterior density function for the parameters and the predictive inference for future survival times from the exponentiated Weibull model, assuming that the observed breast cancer survival data follow such type of model. The Markov chain Monte Carlo method was used to determine the inference for the parameters. Results: The summary results of certain demographic and socio-economic variables are reported. It was found that the exponentiated Weibull model fits the male survival data. Statistical inferences of the posterior parameters are presented. Mean predictive survival times, 95% predictive intervals, predictive skewness and kurtosis were obtained. Conclusions: The findings will hopefully be useful in treatment planning, healthcare resource allocation, and may motivate future research on breast cancer related survival issues.

The goal of this study was to investigate some significant factors to influence level of safety at plant construction field and analyze degree of risk by work classification. Currently, there are lots of construction fields for the nuclear power plant for electricity generation, and our government also planned constructing more nuclear power plant in near future. However, much of the safety literature neglected the degree of risk factors on the plant construction field. Safety managers participated in the brainstorming session for drawing decision criteria of the degree of risk (i.e., significant factors). Then, they were asked to answer a structured questionnaire which was developed for drawing most important factors. Finally, the analytic hierarchy process (AHP) was used to analyze level of risk by work classification. The following results were obtained. First, total twelve factors judging degree of risk were found in the brainstorming session. Second, the questionnaire showed four significant factors, including number of workers, working environments, skill of craft and accident experience. Third, the results of AHP showed Architecture work is the most dangerous work among 6 work types. The results could be used to reduce degree of risk in construction field of the nuclear power plant.

We presented a mapping the work function of the vanadium pentoxide ($V_2O_5$) nanonet structures by scanning Kelvin probe microscopy (SKPM). In this measurement, the $V_2O_5$ nanonet was self-assembled via dropping the solution of $V_2O_5$ nanowires (NWs) onto the $SiO_2$ substrate and drying the solvent, resulting in the networks of $V_2O_5$ NWs. We found that the SKPM signal as a surface potential of $V_2O_5$ nanonet is attributed to the contact potential difference (CPD) between the work functions of the metal tip and the $V_2O_5$ nanonet. We generated the histograms of the CPD signals obtained from the SKPM mapping of the $V_2O_5$ nanonet as well as the highly ordered pyrolytic graphite (HOPG) which is used as a reference for the calibration of the SKPM tip. By using the histogram peaks of the CPD signals, we successfully estimated the work function of ~5.1 eV for the $V_2O_5$ nanonet structures. This work provides a possibility of a nanometer-scale imaging of the work function of the various nanostructures and helps to understand the electrical characteristics of the future electronic devices.
