The purpose of this study was to assess and compare discrepancy in the scores of uncertainty perceived by patients and nurses' interperson perception. For this study, 124 hospitalized patients and the same numbered nurses assigned for direct care of each 124 patients were selected from general ward of C. University Hospital in Seoul during the time period from September to November 1987. Degree of uncertainty was measured by 27 items modified from Mishel Uncertainty in Illness Scale (MUIS), and was utilized by a Likert type scale The data were analysed by Mcnemar-test. Unpaired t-test. ANOVA, Scheffe - test and Stepwise multiple regression. The results are summarized as follows : 1. The discrepancy in the scores of uncertainty perceived by patients and nurses' interperson perception showed significant differences in 23 of 27 items : 11 of 23 items showed that the scores of patients' perception of uncertainty were higher than that of nurses' interperson perception of uncertainty. but 12 of 23 items were revealed reversely. 2. With regard to nurse's demographic variables, the discrepancy scores were the higest in the group under 22 years of age (F＝3.20, p＝.026) and in the group less than 1 year of nursing experience among 4 groups (F＝4.41, p＝.006). 3. The discrepancy scores had a tendency to be lowered in the higher age group(r＝ -.27. p＝.0026) and in the longer experienced group (r＝-.25, p＝.0052). 4. The most important variable affecting the discrepancy scores was identified to be the nurses' age which acounted for 7.2% fo the total variances in the stepwise multiple regression analysis. This was followed by patient hospital days which accounted for an additional 4.5% of the total variances. To conclude, the discrepancy in the scores of uncertainty perceived by patients and nurses' interperson perception showed significant differences in 23 of 27 items. The discrepancy scores of uncertainty had a tendancy to be lowered in the higher age group and in the longer experienced group.

This paper presents a stochastic model predictive control (SMPC) for stop maneuver of autonomous vehicles considering perception uncertainty of stopped vehicle. The vehicle longitudinal motion should achieve both driving comfortability and safety. The comfortable stop maneuver can be performed by mimicking acceleration profile of human driving pattern. In order to implement human-like stop motion, we propose a reference safe inter-distance and velocity model for the longitudinal control system. The SMPC is used to track the reference model which contains the position uncertainty of preceding vehicle as a chance constraint. We conduct simulation studies of deceleration scenarios against stopped vehicle in urban environment. The test results show that proposed SMPC can execute comfortable stop maneuver and guarantee safety simultaneously.

This study aims to find out the influence of the intolerance of uncertainty on entrepreneurial intention by focusing on the start-up support system awareness. While most of existing studies focused on the positive psychological variables and individual environmental characteristics influencing on the entrepreneurial intention, this study has taken a look at the influence of the intolerance of uncertainty as the psychological variable to the entrepreneurial intention to negatively act on the entrepreneurial intention. As a result of the analysis, the intolerance of uncertainty under the control of entrepreneurship and gender is shown to have the negative (-) influence on the entrepreneurial intention and has high level of recognition on the start-up support system perception, and the start-up support system perception is confirmed to have positive (+) influence on the entrepreneurial intention. And, it also indicates that, with respect to the influence of the intolerance of uncertainty on the entrepreneurial intention, the start-up support system perception has the partial medium effect. Following this result of the study, it provides following indications: First the existing studies on the entrepreneurial intention had not covered the intolerance of uncertainty but it is confirmed as the psychological variable with negative influence on the entrepreneurial intention. Second, it is feasible for the preliminary start-up businesses may turn the fear on start-up failure into positive entrepreneurial intention with the start-up support system perception as the leading vehicle. And, third, based on the result, the government should enhance the start-up support system perception even more by seeking ways of efficient publicity to enable more preliminary start-up businesses to participate in diverse start-up support policies. Lastly, it discusses the limitations of this study as well as proposal for ensuing study plans.

The purpose of this study was to investigate the level of uncertainty and anxiety in families of hospitalized children. Data were collected through self-report questionnaires which were constructed to include parent's perception of uncertainty and state anxiety. The subjects consisted of 126 families of hospitalized children in one university-affiliated hospital in Daegu. The data were analyzed by the SPSS program. The results were as follows; 1. The mean score of uncertainty was 64.70 (Range=31-95). The mean scores of subsets of the uncertainty were followed as: lack of clarity (2.59), unpredictability (2.46), lack of information (2.22) and ambiguity (2.14). 2. The mean score of state anxiety was 47.93 (Range=20-67). 3.The level of uncertainty was positively correlated to the level of state anxiety. 4. The level of anxiety was different depending on their religion and monthly income. The above findings indicated that the level of uncertainty and the state anxiety in families of hospitalized children were positively correlated. Therefore, nursing intervention for reducing uncertainty and anxiety and improving coping method should be provided for families of hospitalized children.

Purpose: This concept analysis was done to clarify 'uncertainty in epilepsy'. Methods: Walker and Avant's methodology guided the analysis. In addition, the concept was compared with uncertainty in other health problems. Results: 'Uncertainty in epilepsy' was defined as being in the condition as seen from the epilepsy experience where cues were difficult to understand because they changed, were in discord with past ones, or they had two or more contradictory values at the same time. Uncertainty in epilepsy is evolved from appraisal of the epilepsy experience. As a result, uncertainty leads epilepsy patients, their family or health care providers to impaired functioning and proactive/passive coping behavior. Conclusion: Epilepsy patients with uncertainty need to be supported by nursing strategies for proactive, rational coping behavior. This achievement has implications for interventions aimed at changing perception of epilepsy patients, their families or health care providers who must deal with uncertainty.

The purpose of this study is to identify the effects of the supportive nursing care for arthritis patients enrolled in a rheumatoid clinic. To achieve this purpose, this study adopted a quasi-experimental, pre- and post-test research design, categorized subjects into experimental and control groups. Outpatient clinic nurse alloted the subjects by experimental and control groups and nurse researcher meets the experimental subject with in-depth, direct personal interview and advices via telephone for 8 weeks. During this pre and after the treatment period, the level of pain, uncertainty, self-efficacy, family support, and perception for health were measured. Analyses for the measured results for pre- and post-test showed that the supportive program conducted during this study decreased the level of uncertainty and increased the perception of family support in experimental group. So, the supportive healing interpersonal communication service proved to be effective and this result justifies the argument that the role of the nursing professionals at out-patient clinic should be extended for the more qualified care for the patient.

Purpose: This study aimed to understand the mechanisms of decision regret and stress of family surrogates' end-of-life decision making using an exploratory path model. In particular, the research identified the direct effects of perceptions of uncertainty and effective decisions on decision regret and stress, and examined the indirect effects of being informed, having clear values, and being supported for decision regret and the stress of end-of-life decision making through the mediating variables of perceptions of uncertainty and effective decisions. Methods: Data were collected from 102 family surrogates who had participated in end-of-life decision making for patients with terminal cancer in a tertiary hospital. Results: Perception of effective decisions was a significant direct predictor of decision regret, and uncertainty was a significant predictor of stress among the participants. Being informed, having clear values, and being supported had a significant indirect influence on decision regret through the perception of effective decisions among family surrogates. However, only having clear values had a significant indirect influence on stress through the perception of uncertainty. The model explained 63.0% of decision regret and 20.0% of stress among the participants and showed a good fit with the data, ${\chi}^2=12.40$ (df=8, p=.134), TLI=.97, and RMSEA=.07. Conclusion: Nurses can support family surrogates in end-of-life decision-making processes to decrease their decision regret by providing information about end-of-life care choices, clarifying personal values, and supporting the decision-making process, and to relieve their stress by facilitating the clarification of personal values.

The purpose of this study is to explore the spacial boundary in Kazuyo Sejima's housing architecture, to give attention to contemporary housing architecture that we inhabit, and to escape from existing architectural concepts. This study seeks to the meaning and possibility of the spacial boundary on the basis of contemporary architecture. The spacial boundary can be studied in the aspect of architectural space that molds human experience and perception. As a result of this study, three properties in the spacial boundary are revealed. One property of the spacial boundary is soft that protect privacy from gaze of exterior. Another property is that communication that changes according to material of boundary and its experience of observer. The other property is to have uncertainty by compound of programs and material-mixing senses including its perception. This results means that the spacial boundary as interface which is represent our everyday life in the contemporary housing architecture.
