Due to the recent COVID 19 pandemic, public institutions are increasingly working from home. Working in public institutions is rapidly changing into a smart work environment where time and space constraints disappear. However, many public institutions currently lack a security model for an efficient smart work environment due to the physical network separation system that separates the Internet network and the business network. Therefore, in this paper, we describe the current limitations for implementing smart work in a physical network separation environment of public institutions, and propose a security model necessary for a work environment to supplement them. As a related study, explain SSL VPN and explain smart work business model through security model research of SDP (Software Defined Perimeter), RDP (Remote Desktop Protocol), and VDI (Virtual Desktop Infrastructure) to overcome the security limitations of SSL VPN. As a result, we intend to propose a security model for a smart work environment suitable for public institutions while complying with the physical network separation security guide.

Objectives: Shift work is a stressful situation. It is important to know the factors associated with the ability to adapt to a shift work schedule. The aim of the present study was to investigate the association between sleep, as well as personality variables, and the resilience of shift work nurses. Method: Self-report questionnaires were administered to 95 nurses who worked in one national university hospital. Connor-Davidson resilience scale, hospital anxiety and depression scale, morningness-eveningness scale, Pittsburgh sleep quality index, other sleep-related questionnaires, and Korean defense style questionnaires were used. Results: Age, shift work duration, off-day oversleep, depression, anxiety, adaptive defense style, and self-suppressive defense style were significantly associated with resilience (p < 0.05). Multiple regression analysis showed that age (${\beta}=0.34$, p < 0.05), depression (${\beta}=-0.25$, p < 0.05), adaptive defense style (${\beta}=0.45$, p < 0.001), and self-suppressive defense style (${\beta}=-0.19$, p < 0.05) significantly predicted the resilience of shift work nurses. Concerning individual defense mechanisms, resignation (${\beta}=-0.20$, p < 0.05), sublimation (${\beta}=0.19$, p < 0.05), omnipotence (${\beta}=0.19$, p < 0.05), and humor (${\beta}=0.20$, p < 0.05) significantly predicted the resiliency. Conclusion: The findings indicate that a specific defense style and other mechanisms were associated with the resilience of shift work nurses. A future prospective study with more participants could further clarify the relationship between sleep-related variables, as well as personality factors, and resilience of shift work nurses.

Purpose: Those who access to the nuclear medicine department are classified as radiation workers, temporarily access group, and occasional access group as defined by the atomic energy law. The radiation workers and temporarily access people wear a personal radiation dosimeter for checking their own radiation absorbed dose periodically. However, because of the sanitation workers, classified as temporarily access group, who are working in the nuclear medicine department are moved in a cycle with other departments and their works are changeful, it is hard to control their radiation absorbed dose. Thus, this study is going to examine the state of the sanitation worker's radiation absorbed dose, and then make sure whether they are classified as temporarily access group or not. Materials and methods: In the first instance, the first sanitation worker who works in vitro laboratory and PET room and the second sanitation worker who works in gamma camera rooms (invivo room) wore radiation dosimeter-OSL(Optically Stimulated Luminescence)- to measure their own radiation absorbed dose during work time from May to June 2011. Secondly, this study was taken place 5 places in gamma camera rooms, 2 places in PET bed room, operating room, waiting room and cyclotron room in PET and 4 places in vitro laboratory. And then to measure the radiation space dose rate, it is measured 10 times each of places as sanitation worker's work flow by using radiation survey meter. Results: The radiation absorbed dose on OSL of the first c who works in vitro laboratory and PET room and the second one who works in gamma camera rooms are 0.04, 0.02 mSv per month respectively. That means the estimated annual radiation absorbed doses are less than 1mSv as 0.48, 0.24 mSv/yr respectively. The radiation space dose rates as sanitation worker's work flow using survey meter are 0.0037, 0.0019 mSv/day, so the estimated annual radiation absorbed dose are 0.93, 0.47 mSv/yr respectively. The weighted exposure dose of first sanitation worker of each places are 1.62% in cyclotron room, 3.88% in waiting room, 2.39% in operating room, 81.01% in bed room of PET and 11.01% in vitro laboratory. The weighted exposure dose of second sanitation worker of each places are 45.22% in radiopharmaceutical laboratory, gamma 30.64% in camera rooms, 15.65% in waiting room, 8.49% in reading room. Conclusion: The annual radiation absorbed doses on OSL of both sanitation workers are less than 1 mSv per year and the annual radiation absorbed doses by using survey meter are less than 1mSv either, but close up to 1 mSv. Thus, to clarify whether the sanitation workers are temporarily access group or not, and to be lessen their s radiation absorbed dose, they should be educated about management of radiation and modified their work flow or work time appropriately, their radiation absorbed dose would be lessen certainly.

To date, the majority of research on empowerment has focussed on the individual job incumbent's psychological experience of empowerment and linking this with various work-related outcomes. However, a model that focuses on individual subjective reactions is at best incomplete if it does not include an examination of the contextual factors that shape those perceptions. Therefore, the purpose of this study is to examine the relationships among situational factors, psychological empowerment and employee's attitudes. The data were collected by questionnaire from a sample of 525 employees who were working at business organizations in Kangwon area. Results indicated that organizational characteristics such as access to information, LMX, and participative climate were positively related to an employee's psychological empowerment. Psychological empowerment was positively related to an employee's job attitudes such as organizational commitment and innovative behavior. Finally, theoretical and practical implications from the results were discussed.

Training, unlike education in holistic perspective, not only affects individual's potential of work competencies such as knowledge and technology, but also affects the job performance in organizational perspective. The effectiveness of training for civil servants who participated in mock jury trial learning of Suwon-si was verified using CIPP model. Participants valued the significance of the process of training rather than the conclusion that draws a certain solution, and based on the comparison and analysis of pre·post evaluations, the educational effect of mock trial training and its utilization at work in the future was higher than before the training, proving its effectiveness. In terms of the implications of training programs in addition to the program planner's evaluation, participant constitution in consideration of sex or employment period is needed for learning interaction among various learners, and information acquisition training on various local issues and conflict situations, as well as the combination of deliberation learning, are needed. in addition, it may be supplemented through customized conflict management raining related to pending projects for the effectiveness of training.

This paper suggests a system that can detect malfunctions of the temperature testing equipment, and then notify this information to surroundings using arduino. Precision electronics need a test under extremely high/low temperature using temperature called a chamber. If this chamber have a malfunction situation, the precision electronics under test is damaged and scrapped. Especially when the temperature test is automatically conducted at night with no representative, this system monitors the actual temperature of the tested product in real-time by attaching a temperature sensor to the inside of the test equipment. In case when it is out of the temperature range set up by the tester, the damage to high-priced products can be prevented in the condition of extremely high/low temperature, by turning off the power of the temperature testing equipment, and also notifying this information to the worker at night-time. Regardless of the equipment manufacturers, proposed system in this paper can be applied to all kind of temperature testing equipments, and it can be also produced for low cost.

사례 1>> 요즘 점포 앞 같은 아웃도어 로케이션은 경품을 뽑은 크레인게임기 일색이다. 과거만 해도 자동판매기가 설치되었던 로케이션에서 자판기는 퇴출되고, 크레인게임기가 자리매김한 곳이 많다. 자판기가 설치되어 있는 곳 중에서도 장사도 안하고 흉물스럽게 방치된 로케이션이 많다 사례 2>> 서울에서 자판기 전문점을 운영하는 S씨. S씨 사무실에는 근무하는 사람이 달랑 3명이다. 아내가 경리 및 관리를 맡고 있고, 계약직 직원 한명이 자판기 운영관리를 담당한다. S씨는 간혹 가다 있는 실수요 판매를 진행할 정도이고, 방판 영업은 중단한지 오래이다. 과거 4년여 전만 하도 영업사원을 5명 거느리고 있었지만 시장이 죽자 방판조직을 없애 버린 것. 메이커 전문점의 간판을 걸어 놓고 한 달에 1-2대 기계를 판매하고 있을 뿐이다. 사례 3>> 기자가 취재를 위해 과거 자판기 판매 영업을 잘하기로 유명했던 모유통점 사정에게 연락을 했다. 그러나 그에게 들여오는 말은 실망스러웠다. "이제 자판기 사업은 안하는데요." 자판기 시장이 극도의 침체를 보이다 보니 자판기 영업을 포기하고, 다른 아이템 분야로 사업을 바꿨다. 위의 사례들은 우리 아웃도어 자판기들이 처한 현실을 여실히 보여 준다. 과거만 해도 아웃도어 자판기들은 방문판매 영업의 주 타깃시장으로 자판기 시장 활성화에 중추적인 역할을 했던 게 사실이다. 하지만 시장은 급격하게 몰락을 하여 비전을 잃어버린 시장이 되었다. 아웃도어 자판기들은 하나하나 사라지고 있으며, 자판기 방문판매 시장은 거의 명맥만 이어가고 있을 정도로 심각한 상황이다. 어쩌다 시장이 이렇게 되어 버린 걸까? 자판기 산업의 가장 핵심 로케이션인 아웃도어가 어쩌다가 경쟁력을 읽고 퇴출당하는 상황을 맞고 있는 것일까? 위기의 아웃도어 자판기 시장을 되살린 방법은 과연 없는 것일까?
