스마트폰에 저장되어 있는 정보가 타인에게 접근되는 것을 막기 위해 스마트폰 인증은 매 스마트폰 사용 시 마다 다양한 방법으로 스마트폰 소유자의 여부를 확인한다. 그러나 이러한 매 사용 마다의 인증은 사용자들의 불편함을 야기하며, 때로는 인증방법을 사용하지 않게 하는, 궁극적으로 스마트폰 보안의 치명적인 문제로 작용한다. 본 연구에서는 안드로이드 환경에서 위의 문제를 해결하기 위한 지속 인증 방법을 제안한다. 제안 방법에서 스마트폰들은 사용자들의 과거 경험을 이용하여 그들의 위험을 인식하고 사용자 인증이 필요한지의 여부를 결정한다. 인증은 높은 위험이 있는 상황에서만 진행되기 때문에 제안 방법은 높은 위험도 상황일 경우에는 높은 안전성을, 그리고 낮은 위험도 상황에서는 사용자 편리성을 제공한다.

This study has examined multiple influences of several variables on parenting behavior by looking into illustrative studies. This study provides support to the view that various factors influence parenting and that parenting behavior is multiply determined. Characteristics of parents, children and the context in which parent-child relations occur cause different childrearing patterns among parents. This study can be summarized as follows: 1) Parental behavior is influenced to a large degree by what the parent brings to the situation. In other words, characteristics of the parent including personality characteristics, interpersonal skills, problem-solving skills, level of maturity, values and childrearing beliefs contribute to individual differences in parenting. 2) The parent's relationship history influences the personality characteristics that the parent brings to his or her adult roles. To understand who the parent is today, we have to look at who the parent was, and what the parent was doing in the years prior to parenthood. That is, we need to see the life course of the individual before parenthood. 3) Contextual variables including the immediate context and the larger context have proved to influence parental behaviors. Characteristics of the immediate context such as the quality of marital rationship can influence the parent's psychological well-being and his or her behavior toward the childen while characteristics of the larger context such as the economic situation and the neighborhood can influence the level of stress experienced by the parent and cosequently how the parent relates to his or her child. 4) In order to understand the development of the parent-child relationship we need to look at the characteristics of the child. Children may elicit positive behaviors from their parents, or they may possess characteristics that the parents find aversive thus leading to difficulties in the relationship. Therefore, much depends on the fit beween the characteristics of the parents and characteristics of the child. By examining multiple contemporaneous influences on parenting, this study could deepen the understanding of why parents have different childrearing patterns, why some parents fail to meet their children's demands and why parents act in certain ways. What we ultimately hope is that as we learn more about parenting and the development of parent-child relationships, we will be better able to provide parents with the supports they need to achieve their parenting goals.

When an emergency situation happens in buildings, the top priority is to ensure the occupant from danger as soon as possible. Achieving that goal is a multifaceted and difficult task. However, current evacuation systems have many deficiencies in dealing with the emergency in multi-level structures. The shortage of abilities to continuously update database, predict the future situation and provide the information to users with contextual information is the limit in current systems. Thus, it is very crucial to introduce Evacuation Information System (EIS), which is able to respond quickly to the emergency, and transfer the information to both the administrator and the occupant. The main purpose of this paper is to build EIS on the basis of the indoor Geographical Information System (GIS). When the emergency happens, EIS gives the instruction to Emergency Response Model (ERM) at once. ERM carries out the order and calculates the optimal evacuation routes, then sends the result to EIS. At last, EIS transmits evacuation messages to the occupant who implements evacuation plan. This paper highlights the benefits of EIS in two aspects. One is that EIS can update the data continuously to support evacuation strategy-making. The other is that it can transmit evacuation messages to both the administrator and the occupant.

Purpose: This study aimed to develop a situation-specific theory to explain nurses' experiences of the COVID-19 crisis. Methods: The participants were 16 hospital nurses who experienced the COVID-19 crisis. Data were collected through in-depth individual interviews from September 2, 2020 to January 20, 2021. Transcribed interview contents were analyzed using Corbin and Strauss's grounded theory method. Results: A total of 38 concepts and 13 categories were identified through an open coding process. The core category found was becoming a pioneering nurse who turns crises into opportunities. The causal conditions were the chaos of being exposed defenselessly to an unexpected pandemic, fear caused by a nursing care field reminiscent of a battlefield, and moral distress from failing to protect patients' human dignity. The contextual conditions were feeling like the scapegoat of the hospital organization, increasing uncertainty due to the unpredictable state of COVID-19, and relative deprivation due to inappropriate treatment. The central phenomenon was suffering alone while experiencing the dedication of the COVID-19 hero image. The action/interactional strategy were efforts to find a breakthrough and getting the nurse's mind right, and the intervening conditions were gratitude for those who care for broken hearts and getting used to myself with repetitive work. The Consequences were becoming an independent nurse and frustration with the unchanging reality. Conclusion: This study provides the foundation for the nurse's situation-specific theory of the COVID-19 crisis by defining the crisis perceived by nurses who cared for COVID-19 patients and suggesting types of coping with the crisis.

Purpose: The purpose of this study was to conduct a grounded theoretical analysis on the hospital accreditation experience of head nurses in order to understand their behavior on the adaption of this new system. Methods: The participants were 8 head nurses with more than 3 years of experience. The data were collected through in-depth interviews using audiotape recording analyzed by the constant comparative method described in Strauss and Corbin's methodology. Results: There were 113 concepts, 26 subcategories and 12 categories identified through the open coding process. In the axial coding, the following paradigm model was proposed: 1) the causal conditions were 'hardware problem' and 'software problem', 2) the contextual conditions were 'vertical relationship', 'individual preference', and 'family support', 3) the intervening conditions were 'passive conditions' and 'active conditions', 4) the action/interaction strategies were 'leading role' and 'dependent role', 5) the consequences were 'positive acceptance' and 'negative acceptance', 6) the central phenomenon was 'difficult situation' and 7) the core category was 'leading in harmony'. Conclusion: The new system led head nurses having difficulties as the middleman between the hospital administration and general nurses, but they made a continuous effort to overcome and adapt to it through a number of strategies.
