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.

이 연구의 목적은 창의적 문제해결 이론을 토대로 창의적 사고 유형을 측정하기 위한 검사도구인 창의적 문제해결 프로파일 검사(CPSPI: Creative Problem Solving Profile Inventory)를 개발 및 타당화하는 것이다. 기존 검사들의 한계를 보완하기 위해 인지적 선호도와 더불어 인지적 능력을 평가하고, 자신의 아이디어를 타인과 공유하고 설득하는 단계(설득 및 소통)를 포함한 도구를 개발하였다. 초기에는 7단계의 요인, 82문항을 개발하였으며, 문항분석과 구성타당도를 확인하는 과정을 거쳐 최종적으로 5요인, 총 39문항의 검사가 되었다. CPSPI는 개인 내 비교를 통해 창의적 문제해결과정 내에서의 자신의 강점과 약점을 파악할 수 있다는 점에서 자기계발의 교육적 도구로 활용될 수 있을 뿐 아니라, 집단 구성원들의 프로파일을 파악함으로써 상호 간 이해를 도모하여 협력적 창의성 발현에 도움을 줄 것이다.

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.

본 논문에서는 중학생으로 대상으로 디자인 씽킹 기반 인공지능 교육 프로그램을 개발하고 이를 적용하여 창의적 문제해결력에 미치는 영향을 검증하였다. 검사도구는 이화선, 표정민, 최인수(2014)의 CPS 이론을 토대로 창의적 사고유형 능력을 측정하기 위한 검사도구인 창의적 문제해결 프로파일 검사(CPSPI: Creative Problem Solving Profile Inventory)를 사용하였다. CPSPI는 기존 검사들의 한계를 보완하여 인지적 선호도와 인지적 능력을 평가하고, 자신의 아이디어를 타인과 공유하고 설득하는 단계를 포함하였다. 디자인 씽킹 기반 인공지능 교육 프로그램 적용 전 후, 창의적 문제해결력을 분석한 결과, 모든 영역에서 유의미하게 상승하였다. 중학생의 창의적 문제해결력을 분석한 결과 문제발견 및 분석, 아이디어 생성, 실행계획, 실행, 설득 및 소통 영역에서 유의미한 결과가 나타났다. 인공지능교육에서 창의적 문제해결력을 향상시키기 위한 교수학습 방법으로 디자인 씽킹의 효과를 확인하였다.

본 연구는 문제해결능력과 자살사고와의 관계에서 우울의 매개효과를 검증하고자 하였다. 이를 위해 대학생 548명을 대상으로 지각된 문제해결능력 척도, 우울 척도 및 자살사고 척도를 실시하였다. 이들 변인들 간의 관계를 알아보기 위해 상관 분석하였고, 우울의 매개효과를 검증하기 위하여 회귀분석을 실시하였다. 연구 결과 문제해결능력과 우울 및 자살사고 간에 유의한 정적 상관을 보였고, 문제해결능력과 자살사고 간의 관계에서 우울의 매개효과가 검증되었다. 즉 지각된 문제해결능력은 자살사고에 직접 영향을 미치기보다는 우울을 매개로 간접적으로 영향을 미치는 것으로 확인되었다. 이 같은 연구결과는 자살사고에 영향을 미치는 우울과 문제해결능력에 대한 중재의 중요성을 시사하였다.
