This study develops an the ideal portrait of a human being pursuing in home economics education from a critical science perspective. The practical problem is 'what should the ideal portrait of a human being pursuing in home economics education with a critical science perspective be?' was addressed through a practical reasoning research method with the stages of valued ends, context, alternatives, consequence, and a final plan. The sequential flow of understanding values and contexts established the setting of three valued ends by organizing issues and categorized areas of individuals, families, society, and cultural from a critical science perspective. The ideal portrait of human being was specifically stated, in the self-formation, independent, inter-subjectivity, social participation, and enculturation according to subcategories; in addition, the stated ideal portrait of human being was modified through expert consultations. Alternatives and consequences were reexamined for the validity of the statement and restated as a comprehensive statement of ideal portrait of a human being that included a restatement of the five areas. An ideal portrait of a human being pursuing in home economics education from a critical science perspective was made from alternative ideal portraits of the proposed human being and stated as 'a person who can continually act autonomously in one's life-world.'

기업경영에 있어서 성과측정 시스템은 매우 중요하다. 측정이 있어야 문제점을 파악하고, 개선할 수 있기 때문이다. 기업의 유형자산은 재무제표나 손익계산서 등의 구체적인 금액으로 측정이 가능하나 기업의 무형자산은 지금까지 객관적이고 정량적인 측정방법을 볼 수 없었다. 이에 본 연구는 기업의 지적자산을 측정하는 모델을 통하여 건설기업의 무형자산(지적자산)의 크기를 객관적으로 정량화 시킬 수 있는 모델을 제시하고, 측정방법의 발전방향을 제시하고자 한다.

Purpose: This descriptive study examined awareness of and ethical attitudes associated with Do Not Resuscitate (DNR) orders in 119 emergency medical technicians (EMTs). Method: In total, 255 paramedics and basic EMTs completed questionnaires between March and May, 2013. Data were analyzed using the SPSS WIN 18.0 program. Results: A chi-square analysis revealed significantly different responses given by paramedics and basic EMTs: Paramedics gave "the reason in which DNR is not necessary", as being "due to unclear DNR decision time" whereas basic EMTs answered that this was "due to a legal problem" ($x^2$ = 12.680, p < .05). Paramedics disagreed with the statement, "It is natural for medical teams to have less interest in patients with DNT orders", whereas basic EMTs agreed with the statement ($x^2$ = 6.666, p < .05). Conclusion: A unified manual on attitude toward DNR orders, taking account of social and culture factors, needs to be developed. This research provides a base line for future research.

PBL can be defined as an active, self-directed and student-centered learning, and an opposite way of classroom teacher-centered learning which has been traditional role learning. PBL enables students think more efficiently and effectively when puzzling through the patient problems. The purpose of this study is to find out the perception of student nurse about PBL, the characteristics and the structure of the type for PBL. The research process is as follow : First, the researcher selected 35 statements for PBL with the content analysis of in depth interview and the literature review. Second, the researcher asks 38 student nurse to classify the statement cards. The result of the research is that the type of student nurse's PBL perception is divided into 4 types(Affirmative type, Negative type, Suspicious type, and Preferable type), and the explanative total variance is 44 percent. In relation to this, if PBL well combined and adapted in our traditional curriculum will change our nursing education in better direction.

In this paper, the problem of axisymmetric deformation of the circular membrane fixed at its perimeter under the action of uniformly-distributed loads was resolved by exactly using power series method, and the solution of the problem was presented. An investigation into the so-called Hencky transformation was carried out, based on the solution presented here. The results obtained here indicate that the well-known Hencky solution is, without doubt, correct, but in the published papers the statement about its derivation is incorrect, and the so-called Hencky transformation is invalid and hence may not be extended to use as a general mathematical method.

Our networked world has been growing exponentially fast. The explosion in volume of machine-to-machine (M2M) transactions threatens to exceed the transport capacity of the networks that link them. Therefore, it is quite essential to reconsider the tradeoff between using many data sets versus using good data sets. We focus on this tradeoff in the context of the quality of information aggregated from many sensors in a noisy environment. We start with a basic theoretical model considered in the famous "CEO problem'' in the field of information theory. From a point of view of large deviations, we successfully find a simple statement for the optimal strategies under the limited network capacity condition. Moreover, we propose an open problem for a sensor network scenario and report a numerical result.

As the stock market is affected by various circumstances including economic and political variables, predicting the stock market is considered a still open problem. When combined with corporate financial statement data analysis, which is used as fundamental analysis, and technical analysis with a short data generation cycle, there is a problem that the time domain does not match. Our proposed method, LSTE the operating profit and market outlook of a petrochemical company and estimates the sales and operating profit of the company, it was possible to solve the above-mentioned problems and improve the accuracy of stock price prediction. Extensive experiments on real-world stock data show that our method outperforms the 8.58% relative improvements on average w.r.t. accuracy.

정보 검색 시스템에서 문서의 내용을 대표하는 용어를 추출하거나 정보 추출 및 텍스트 마이닝에서 특정 정보만을 추출하려면 고유명사에 대한 대용어 문제가 해결되어야 한다. 대용어 해소 문제는 인칭 명사에 대한 대명사의 선행사 결정 문제가 대표적이다. 본 논문에서는 한국어에서 문서의 내용을 보다 정확히 분석하기 위해 3인칭 대명사 “그/그녀/그들/그녀들”의 선행사를 결정하는 방법을 제안한다. 일반적으로 3인칭 대명사의 선행사는 현재 문장 또는 이전 문장의 주어인 경우가 많고, 또한 3인칭 대명사가 2회 이상 반복되는 경우가 자주 발생한다. 이러한 특성을 이용하여 현재 문장과 이전 문장에 출현한 인칭 명사들 중에서 선행사로 사용되는 경우를 조사하여 선행사 결정 규칙을 발견하였다. 이 경험 규칙은 3인칭 대명사의 격에 따라 조금씩 달라지기 때문에 대명사의 격에 따라 주격, 목적격, 소유격으로 구분하여 기술하였다. 제안한 방법의 타당성을 검증하기 위하여 신문 기사의 정치 관련 문서에서 대명사의 격에 따라 100개씩 총 300개의 실험 대상을 선정하였으며, 실험 결과로 3인칭 대명사의 선행사 결정 정확도는 재현율이 79.0%, 정확률이 86.8%로 나타났다.

본 연구는 문제 만들기 활동과 수학 수업을 통합할 수 있는 실제적 방안을 모색하고자 수행되었다. 이를 위해 일상적으로 이루어지는 수학 수업의 정리 단계에서 문제 만들기 활동을 실행하고, 학생들이 만든 문제를 체계적인 절차와 준거를 사용해 분석하였다. 먼저 학생들이 만든 540문제 중 수학적으로 해결 가능한 문제는 81%, 오류가 있는 문제는 18%로 나타났다. 이어서 수학적으로 해결 가능한 문제를 복잡성 수준에 따라 분석하였는데, 상-수준 13%, 중-수준 30%, 하-수준 57%였다. 마지막으로 오류 유형으로 분류된 비-수학적 문제, 단순한 진술, 해결 불가능 문제는 학생들의 성취 수준과 학습 내용에 따라 다양하게 분포되어 있었다. 본 연구는 학생들이 생성한 문제를 분석하기 위한 체계적인 절차와 준거를 제시하고 수학 수업과 문제 만들기 활동을 통합할 수 있는 방향을 제시했다는 점에서 의의를 찾을 수 있다.

This paper presents an optimal pattern for distributing stiffness along a framed tube structure through an analytic equation, which may be used during the preliminary design stage. Most studies in this field are computationally intensive and time consuming, while a hand-calculation method, as presented here, is a more suitable tool for sensitivity analyses and parametric studies. Approach in development of the analytic model is to minimize the mean compliance (external work) for a given volume of material. A variational statement of the problem is made, and a specified deformation-profile is obtained as the necessary condition for a minimum; enforcing this condition, stiffness is then computed. Due to some near-zero values for stiffness, the problem is modified by considering a lower bound constraint. To deal with this constraint, the design domain is assumed to be divided into two zones of constant stiffness and constant curvature; and the problem is restated in terms of these concepts. It will be shown that this methodology allows for easy computation of stiffness through an analytic and dimensionless equation, valid in any system of units. To show practicality of the proposed method, a tubed-system structure with uniform stiffness distribution is redesigned using the proposed model. Comparative analyses of the results reveal that in addition to simplicity of the proposed method, it provides a rather high degree of accuracy for real-world problems.
