The primary objective of task scheduling involves scheduling the task on resources and minimizing the objective of the schedule. In this study, we proposed mean grey wolf optimization algorithm to enhance the system performance there by depleting the scheduling issues. The main objective of this method is minimizing the makespan and energy consumption. The objective of the proposed algorithms has been evaluated using CloudSim toolkit for standard workload (left-skewed & right-skewed). The outcome of the simulation result shows that the proposed Mean GWO algorithm renders comparatively ample result than the other existing algorithms.

The mobile device has been widely used in many areas. Task offloading is always used to overcome the limitation of processing ability and energy-supply of the mobile devices in the mobile cloud environment. Most researches suppose we know the detail of task (number of instructions) of every sub-task. But most of time, to get the detail of a task is very difficult. This paper uses the grey number to express that uncertain information and propose method to evaluate the performance of offloading tasks. Simulations show that our method selects the solution with the lowest energy consumption.

With the development of mobile edge computing, how to utilize the computing power of edge computing to effectively and efficiently offload data and to compute offloading is of great research value. This paper studies the computation offloading problem of multi-user and multi-server in mobile edge computing. Firstly, in order to minimize system energy consumption, the problem is modeled by considering the joint optimization of the offloading strategy and the wireless and computing resource allocation in a multi-user and multi-server scenario. Additionally, this paper explores the computation offloading scheme to optimize the overall cost. As the centralized optimization method is an NP problem, the game method is used to achieve effective computation offloading in a distributed manner. The decision problem of distributed computation offloading between the mobile equipment is modeled as a multi-user computation offloading game. There is a Nash equilibrium in this game, and it can be achieved by a limited number of iterations. Then, we propose a distributed computation offloading algorithm, which first calculates offloading weights, and then distributedly iterates by the time slot to update the computation offloading decision. Finally, the algorithm is verified by simulation experiments. Simulation results show that our proposed algorithm can achieve the balance by a limited number of iterations. At the same time, the algorithm outperforms several other advanced computation offloading algorithms in terms of the number of users and overall overheads for beneficial decision-making.

As autonomous driving and connected car technology advance, various deep learning applications for autonomous vehicles and complex traffic situations are increasing. Autonomous vehicles must collect and process vast amounts of sensor data to support various deep learning applications, but vehicles have limited computing resources to perform complex deep learning operations. Therefore, edge computing is a promising solution to complement the limitations of autonomous vehicles. In this paper, we design edge computing for efficient task processing in an autonomous driving environment using a driving simulator. Also, we propose a task scheduling and offloading method which determines the target server to offload a task according to the characteristics of the task and the computing resources. The effectiveness of the proposed method is verified through experimental evaluation in an autonomous driving environment, supporting multiple deep learning services that we established by using a driving simulator.

본 연구는 개인-환경 적합성이 과업성과에 영향을 미치는 과정에서 나타나는 교환적 동기인 심리적 계약과 내재적 동기인 소명의식이라는 두 가지 핵심 심리적 요인에 주목하여, 이 두 매개 변수를 개별적으로만 다루는 기존 연구의 한계를 넘어 심리적 계약과 소명의식이라는 이중 매개 경로를 통합적으로 탐색하고자 한다. 중소규모 2개 대학 249명의 구성원을 대상으로 연구하였다. 심리적 계약 및 소명의식의 이중매개효 과를 분석하기 위해 Process Macro Model 6을 사용하여 연구를 진행하였다. 연구결과, 개인-환경 적합성 중 개인-직무 적합성만이 과업성과에 직접적인 영향에 대해서는 통계적으로 유의한 영향을 미치는 것으로 확인되었다. 개인-환경 적합성이 과업성과에 미치는 영향에 관한 심리적 계약과 소명의식의 단일매개효과는 세 하위 요인 모두가 통계적으로 유의미한 결과를 나타내지 않았다. 마지막으로 확인된 개인-환경 적합성 이 과업성과에 미치는 영향에 관한 심리적 계약과 소명의식의 이중매개효과는 모두 통계적으로 유의미한 정(+)의 효과가 순차적 연쇄효과로 나타나는 중요성으로 이해할 수 있다. 이론적 시사점으로는 개인-환경 적합성이 과업성과에 도달하는 경로가 단일 심리 변수로 단순화되지 않 는 복합적이고 순차적인 심리적 과정을 거친다는 점을 실증한 동시에 심리적 계약과 소명의식이라는 두 핵심 심리적 변수의 차별성을 분명하 게 인식한 것이다. 또한 소명의식이 성과창출로 이어지는 것에 있어서 실현 환경의 중요성을 확인함으로써 소명의식 연구를 확장시킨다. 실무 적 시사점으로는 개인-환경 적합성의 관리 패러다임을 채용 단계를 넘어선 종합적인 HRM 시스템 설계로 전환해야 한다는 것이다. 또한 소명 의식을 단순한 개인적 특성이 아닌 조직의 전략적 관리 요인으로 전환해야 한다는 것이다. 경영컨설팅에 관한 시사점은 개인-환경 적합성을 관 리하는 종합적인 시스템을 제안할 수 있다. 또한 소명의식에 대한 성과와의 연계성을 강조하고 이를 지원하는 경력개발 프로그램이나 교육프 로그램을 설계하여 제안할 수 있을 것이다. 소명의식의 발현을 강화할 수 있도록 조직문화 개선 활동 관점에서 통합적 활동을 기획하여 지원할 수 있다는 것이다. 이러한 시사점에도 불구하고 효과성의 객관성을 높이기 위해 향후 연구에서는 과업성과를 양적 변수로 측정하는 것을 고려 하여야 한다. 또한 종속변수를 과업성과 뿐만 아니라 직접적인 영향 요인인 태도, 행동, 정서적 측면 등으로 확장하여 연구하는 것이 필요하다. 대학이라는 교육기관을 대상으로 한 연구로 일반기업으로의 확장을 위한 추가 연구도 요구된다.

This study focuses on two key psychological factors, psychological contract, which is an exchange motive, and sense of vocation, which is an intrinsic motive, by paying attention to two key psychological factors that appear in the process of affecting task performance by individual-environmental suitability, and attempts to explore the dual mediating path of psychological contract and sense of vocation in an integrated manner beyond the limitations of existing research that deals only with these two parameters individually. This study was conducted with 249 members of two small and medium-sized universities. In order to analyze the dual mediating effect of psychological contract and sense of vocation, the study was conducted using Process Macro Model 6. As a result of the study, it was confirmed that only individual-job suitability had a statistically significant effect on task performance among individual-environmental suitability. The single mediating effect of psychological contract and sense of vocation on the effect of individual-environmental suitability on task performance did not show statistically significant results for all three sub-factors. Finally, both the psychological contract and the double mediating effect of the sense of vocation on the effect of individual-environmental suitability on task performance can be understood as the importance of showing a statistically significant positive (+) effect as a sequential chain effect. The theoretical implication is that the path through which individual-environmental suitability reaches task performance goes through a complex and sequential psychological process that is not simplified into a single psychological variable, while at the same time clearly recognizing the difference between the two key psychological variables, psychological contracts and a sense of vocation. In addition, the study of the sense of vocation is expanded by confirming the importance of the realization environment in that the sense of vocation leads to performance creation. The practical implication is that the management paradigm of individual-environmental suitability should be transformed into a comprehensive HRM system design beyond the recruitment stage. In addition, the sense of vocation should be converted into an organization's strategic management factor rather than a simple personal characteristic. The implications of management consulting can propose a comprehensive system to manage individual-environmental suitability. In addition, it will be possible to design and propose a career development program or educational program that emphasizes the connection with the performance of the sense of vocation and supports it. In order to reinforce the expression of the sense of vocation, integrated activities can be planned and supported from the perspective of organizational culture improvement activities. Despite these implications, in order to increase the objectivity of effectiveness, future studies should consider measuring task performance as a quantitative variable. In addition, it is necessary to expand and study the dependent variable not only to task performance but also to attitude, behavior, and emotional aspects, which are direct influencing factors. This is a study on an educational institution called a university, and additional research is also required to expand to general companies.

Recently, the cloud environment is changing from a single cloud to a multi-cloud environment for service safety and efficient management. However, the multi-cloud service has a problem that the security and cost problems have not yet been completely solved. In this paper, we propose a multi-cloud task management technology to maximize interoperability in a multi-cloud environment. The proposed technology improves task quality and improves integrated management by applying correlation to multi-cloud tasks in various environments. In addition, the proposed technique recovers the damaged location of cloud tasks stored in the block by sharing various elements (time, place, URL, etc.) so that cloud tasks can be collected, processed, and stored on a cloud server and shared with different cloud users. As a result of performance evaluation, the accuracy of cloud task processing improved by 3.52%, the efficiency by 2.84% on average, and the latency by 1.02 ms on average.

Recent advancements in artificial intelligence technology have led to its extensive integration in various aspects of the automotive industry. Vehicles are no longer perceived solely as means of transportation; they now play a central role in providing a multitude of services to drivers and passengers through enhanced mobility and connectivity. However, to deliver such services, substantial computing resources are required, highlighting the growing importance of cloud computing. Nevertheless, cloud computing faces challenges in ensuring Quality of Service (QoS) due to processing speed and network latency issues. In response to these challenges, the significance of Vehicle Edge Computing (VEC) and the concept of Parked Vehicle Edge Computing (PVEC) have been proposed. Parked Vehicle Edge Computing leverages the resources of parked vehicles to process tasks at the edge server. This technology harnesses the idle computing resources of parked vehicles during their downtime, thereby improving services and generating revenue. This paper introduces techniques that utilize game theory concepts such as coalition formation games, VCG mechanisms, and Shapley value to promote collaboration among parked vehicles and efficiently distribute tasks. The proposed methods effectively utilize the resources of parked vehicles in the PVEC platform, enhancing service quality and demonstrating their performance through evaluation and comparison. This suggests a novel approach to leveraging the onboard resources of parked vehicles to enhance service quality.

Purpose: This study was aimed at (a) describing professional nursing practice environments embedded in nursing care units and (b) examining its relationships to nurses' task motivation. Method: Using the Nursing Work Index Revised (NWI-R) and the Work Preference Inventory (WPI), a descriptive study was conducted with a sample of 320 registered nurses on 26 nursing care units in one University hospital in Korea. Result: Mean scores were 12.9 on a 5-20 score range of an autonomous environment scale, 7.3 on a 3-12 score range of a collaborative environment, and 15.8 on a 7-28 score range of control over nursing practice. Nurses' age, educational level, job position, working period at the hospital and employment status were significantly related to the degree of a professional practice environment. The extent to which a professional practice environment accounted for task motivation was $19.5\%$. Conclusion: There is a certain degree of professionalism in the workplace environment that nurses perceived within the nursing care units. When nurses care for patients, the degree of task motivation depends on the work environment supporting the professional nursing practice.

연합 학습(FL)은 여러 공동 작업자 간에 분산된 모델 학습을 위한 강력한 방법론으로 부상해 데이터 공유의 필요성을 없애준다. FL은 데이터 프라이버시를 보호하는 기능으로 호평을 받고 있지만, 다양한 유형의 프라이버시 공격으로부터 자유롭지 않다. 대표적인 개인정보 보호 기술인 차분 프라이버시(DP)는 이러한 취약점에 대응하기 위해 널리 사용된다. 이 논문에서는 기존의 작업별 적응형 DP 메커니즘을 FL 환경에 적용해 성능을 평가한다. 포괄적인 분석을 통해 다양한 DP 메커니즘이 공유 글로벌 모델의 성능에 미치는 영향을 평가하며, 특히 다양한 데이터 배포 및 분할 스키마에 주의를 기울인다. 이를 통해, FL에서 개인정보 보호와 유용성 간의 복잡한 상호 작용에 대한 이해를 심화하고, 성능 저하 없이 데이터를 보호할 수 있는 검증된 방법론을 제공한다.

Federated Learning (FL) has emerged as a potent methodology for decentralized model training across multiple collaborators, eliminating the need for data sharing. Although FL is lauded for its capacity to preserve data privacy, it is not impervious to various types of privacy attacks. Differential Privacy (DP), recognized as the golden standard in privacy-preservation techniques, is widely employed to counteract these vulnerabilities. This paper makes a specific contribution by applying an existing, task-specific adaptive DP mechanism to the FL environment. Our comprehensive analysis evaluates the impact of this mechanism on the performance of a shared global model, with particular attention to varying data distribution and partitioning schemes. This study deepens the understanding of the complex interplay between privacy and utility in FL, providing a validated methodology for securing data without compromising performance.

Metabus, a three-dimensional virtual environment for digital communication, has gained a lot of attention recently. Even so, there are still many unanswered questions about the user's consciousness and behavior. A difference in nature from conventional digital communication is also unclear. This paper aims to study Metabus on a hypothetical premise by organizing the possibility of Metabus for communication activation based on a research project aimed at using Metabus to support the formation of a community of school dormitories and studio rental residents. After reviewing the establishment process and application cases of Metabus, we focus on the character (avatar) used as the user's alter ego within the metabus, which will allow customization of both form and content different from text-based communication. The "physicality" and the "spatiality" of the metaverse and the "immersion" they bring are among the most important, functional innovations. Based on this summary, a case of using metabuses will be reviewed to describe the research plan aimed at supporting community formation.

직무열의는 강한 몰입을 기반으로 자발적으로 자신의 역할을 수행하는 동기요소이다. 본 연구에서는 조직 내에서 평가의 패러다임을 넘어 직무동기를 자극하는 성과관리 관점에서 직무열의에 영향을 주는 피드백 관련 요소를 고찰하였다. 직무열의와 관련되는 요인으로 개인 차원에서 팀 리더의 성과코칭을, 팀 수준에서 과업 상호의존성이 조직의 공식구조 측면에서 미치는 영향을 살펴보았다. 이 관계에서 팀 구성원에 대한 팀 리더의 성과코칭이 개인의 직무열의에 미치는 영향을 인사평가효과성이 매개하는지를 검증하였고, 팀 수준에서 과업상호의존성이 직무열의에 미치는 교차수준의 영향을 팀 수준의 피드백환경이 매개하는지 알아보았다. 연구를 위해 29개 팀에서 214명의 자료를 수집하였다. 개인수준의 가설검증은 팀의 영향력에 의한 변산성을 고려하면서 매개효과를 검증하는 분석방법을 채택하여 검증하였으며, 팀수준의 효과는 가설에서 설정한 매개경로 외에도 개인수준의 매개변인을 통하는 경로도 가능하므로 제안모형의 경로와 대안적인 경로를 모두 검증하여 비교하였다. 분석 결과 가설의 개인수준에서 설정한 모형처럼 평가효과성은 성과코칭과 직무열의를 매개하였으며, 피드백환경은 과업상호의존성과 직무열의를 부분적으로 매개하였고 대안적인 경로보다 설명력이 더 큰 것으로 나타났다. 본 연구는 조직의 공식적, 비공식적 성과관리 전략을 통하여 구성원의 직무열의를 높일 수 있다는 면에서 연구의 의의를 제시하였다.

Job engagement is a motivating factor for the self-driven role performance based on strong involvement. Following the performance management perspective that expands from a simple evaluation paradigm to stimulate work motivation, the current study investigated feedback-related factors that influence on job engagement. As factors that are associated with job engagement in the formal structural aspects in organizations, the performance coaching of team leaders at the individual-level and the task interdependence at the team-level were examined. The study also investigated the mediation role of performance appraisal effectiveness between performance coaching and job engagement, and the cross-level mediation effect of feedback environment at the team level between task interdependence and job engagement. Using the survey research method, data were collected from 214 employees in 29 teams. The individual-level hypotheses were tested by adopting an analytical method that examines the mediation effect controlling for the team influence, and the team-level hypotheses were tested not only for the suggested mediation path but also for the possible alternative path through the individual-level mediator. The results of the analyses showed that there was a partial mediation role of appraisal effectiveness from performance coaching toward job engagement. The results also showed that a significant cross-level mediation effect of feedback environment on the job engagement from task interdependence, which explains mediation processes better than the alternative path. The current study has provided implications for ways to stimulate job engagement through formal and informal performance management strategies in organizations.
