Purpose: The aim of this study was to determine the predictive strength of students' self-efficacy, problem-solving skills, and other characteristics in performing intravenous practices and monitor phlebitis and infiltration. Methods: This cross-sectional study was carried out with 736 third and fourth-year students studying at the Health Sciences Faculties of Balikesir and Sakarya universities. The data were collected using the Self-Efficacy Scale, Problem-Solving Inventory and Catheter Care and Infiltration Monitoring Questionnaire. Results: The participants' mean Catheter Care and Infiltration Monitoring Questionnaire score significantly and positively correlated with their mean Self-Efficacy Scale score on a moderate level (r=.25; p<.001) but significantly and negatively correlated with their mean Problem-Solving Inventory score on a moderate level (r=-.21; p<.001). In other words, because a low Problem-Solving Inventory score indicates that the person's problem-solving skill is high, the Care and Infiltration Monitoring Questionnaire score increased as the problem-solving skill increased. While the Self-Efficacy Scale predicted the year of study and catheter care and infiltration monitoring variables positively, the Problem-Solving Inventory predicted the satisfaction with the profession variable negatively. Conclusion: Self-efficacy, problem-solving, liking the profession, and year of study predict success in catheter care and infiltration monitoring. For this reason, guidance may be provided in the development of a comprehensive education system toward increasing students' problem-solving skills, self-efficacy, and professional knowledge and skills.

This paper considers the robust inventory control problem introduced by Bertsimas and Thiele [4]. In their paper, they have shown that the robust version of the inventory control problem can be solved by solving a nominal inventory problem which is formulated as a mixed integer program. As a proper generalization of the model, we consider the problem with non-stationary cost. In this paper, we show that the generalized version can also be solved by solving a nominal inventory problem. Furthermore, we show that the problem can be solved efficiently.

Purpose: The purpose of this study was to develop a Korean problem solving process inventory (K-PSPI) for adults. Method: A conceptual framework for the adult problem solving process, and 40 preliminary questions were developed based on references and expert consultations. After a pilot test, preliminary questions were further refined. The final inventory of 30 items was tested with 1,500 adults. The validity and reliability of the K-PSPI were tested by factor analysis using the SPSS Windows 12.0 program. Results: Through factor analysis on the final 30 questions, 5 factors were identified and cumulative variant of the factors was 52.15%. For the test of reliability of the 30 questions on the problem-solving process, The Cronbach alpha was .93. Conclusion: This study showed that the K-PSPI is a systematic method with verifies reliability and validity. It is not only adequate for the actual circumstance and culture of Korean adults, but is also a useful instrument to test post-action problem solving ability.

The present study examined predictors of children's problem solving using structural equation modeling(SEM). Participants were 410 dyads of 2nd- and 6th-grade children and their mother or father. Children and their parents responded to questionnaires. Instruments were the PSI(Parent Behavior Inventory, 1998), CES-D(Center for Epidemiological Scale-Depression, for children's depression, 1977) Sherer's(1982) self-efficacy scale, and the Problem Solving Inventory(Heppner & Petersen, 1982). In both grades, warmth in parenting behavior affected children's self-efficacy, which in turn contributed to their problem solving. Rejection in parenting behavior had positive effects on problem solving through increasing self-efficacy in 2nd graders only. Results implied importance of self-efficacy and developmentally appropriate parenting to improve children's problem solving.

This study aims to develop and validate Creative Problem Solving Profile Inventory (CPSPI) which is a scale to measure the creative thinking style, based on the CPS theory. For redeeming the limits of existing scales, this study developed an inventory which includes an evaluation for cognitive ability as well as cognitive preference and the stage to share an idea with others and persuade (Persuasion & communication stage). At the early stage, 7 factors (stages) and 82 items were developed and finally, 5 factors and 39 items were selected through item analysis and validation of construct validity. In conclusion, CPSPI will be used as an educational tool for self-development by knowing own's strengths and weaknesses in the creative problem-solving process, and help in displaying cooperative creativity by understanding other people and interaction, based on creative thinking profiles of group members.

In this paper we propose an effective genetic algorithm for solving the integrated inventory and routing problem of supply chain composed of multi-warehouses and multi-retailers. Unlike extant studies dealing with integrated inventory and routing problem of supply chain, our model incorporates more realistic aspect such as positive inventory at the multi-warehouses under the assumption of inventory policy of power of two-replenishment-cycle. The objective is to determine replenishment intervals for the retailers and warehouses as well as the vehicles routes so that the total cost of delivery and inventory cost is minimized. A notable feature of our algorithm is that the procedure for evaluating the fitness of objective function has the computational complexity closing to linear function. Computational results show effectiveness of our algorithm.

The purpose of this study is explore stress, problem solving and emotional intelligence in nursing students. Participants were recruited from December 2016 to February 2017 by web base survey. The participants were 237 who nursing students in university. Stress, problem solving and emotional intelligence were assessed using two questionnaires; Korean version of the Perceived stress inventory (PSI), problem solving, and Wong and Law Emotional Intelligence Scale (WLEIS). The responses 237 students were analyzed statistically. Significantly emotional intelligence was a correlation stress and problem solving (p>.001). The findings showed that problem solving (${\beta}=.386$), stress (${\beta}=-.259$, empathy ability (${\beta}=.144$), and satisfaction with a major in nursing (${\beta}=.129$). Our finding show that stress levels of low and the problem solving levels of above moderate in emotional intelligence. Especially, the problem solving was important factor in emotional intelligence.

Purpose: This study was done to identify the relationship between critical thinking disposition and problem solving ability in nursing students, thereby providing basic data for nursing education. Method: A convenience sample was drawn from 161 nursing students. Data were collected from June 2008 to October 2008. Instruments used in the study were the California Critical Thinking Disposition Inventory (CCTDI) developed by Facione & Facione (1992) and the Problem Solving Inventory (PSI) developed by Heppner & Petersen (1982). The collected data were analyzed using t-test, ANOVA, Scheffe' test, Pearson correlation coefficients and multiple regression with SPSS 12.0. Results: The total mean score for CCTDI was 278.41 and PSI was 119.23. For general characteristics, there were statistically significant differences in CCTDI according to satisfaction with nursing majors (F=6.29, p=.00) and PSI according to academic achievement (F=3.45, p=.02) and marital status (t=2.43, p=.02). A statistically significant negative correlation was found between CCTDI and PSI. Critical thinking self-confidence, Analyticity and Inquisitiveness were significant predictors of PSI. Conclusion: The findings of this study indicate that critical thinking disposition influences problem solving ability. Therefore, the findings provide significant basic data for nursing education and nursing practice.

In this paper, we developed a design thinking-based artificial intelligence education program for middle school students and applied it to verify the impact on creative problem-solving skills. The inspection tool used the Creative Problem Solving Profile Inventory (CPSPI), an inspection tool for measuring creative thinking type ability based on the CPS theory of Hwasun Lee, Jungmin Pyo, Insoo Choe(2014). CPSPI included the steps of evaluating cognitive preferences and cognitive abilities by supplementing the limitations of existing tests, and sharing and persuading one's ideas with others. Before and after applying the design thinking-based artificial intelligence education program, as a result of analyzing the creative problem-solving ability, it increased significantly in all areas. As a result of analyzing the creative problem-solving ability of middle school students, significant results were found in the areas of Problem Detection and Analysis, Idea Generation, Action plan, Execution, Persuasion and Communication. The effect of design thinking was confirmed as a teaching and learning method to improve creative problem-solving ability in artificial intelligence education.

This study investigated the mediating effects of depression on the relationship between perceived problem solving ability and suicidal ideation. 548 college students were examined with PSI(Problem Solving Inventory), BDI(Beck Depression Inventory) and SSI(Scale for Suicidal Ideation). To explore the relationship among these variables, correlation analysis was undertaken. Regression analysis was then applied to test the mediating effects of depression. In the results, perceived problem solving ability, depression and suicidal ideation were correlated positively. Depression operated as a factor to mediate between the perceived problem solving ability and suicidal ideation. This mean that perceived problem solving ability impact indirectly, rather than directly, on suicidal ideation. These results suggest the importance of psychological intervention to improve depression and perceived problem solving ability that affect suicidal ideation.
