  • 본 연구에서는 NURBS 기반 아이소 지오메트릭 쉘 해석을 위해 다중 패치 해석 모델을 정식화하였다. 기존 연구를 통해 개발된 단일 패치로 구성된 전단 변형을 고려한 쉘 요소에 대해 일반 좌표계에서 기하학적으로 엄밀한 쉘 구조물의 아이소 지오메트릭 해석 모델을 도입하고 매개변수 연속성을 고려하여 다중 패치 모델로 확장하였다. 인접 곡면의 노트 요소가 결합 경계를 통해 조화를 이루는 경우에 대해 0차와 1차 매개변수 연속성 조건을 고려하였으며, 두 패치 간 마스터-슬레이브 관계를 정립하여 종속된 한 곡면의 자유도를 상대 곡면의 자유도로 표시하여 모델 크기를 줄이면서 두 곡면을 결합하였다. 다중 패치 쉘 예제에 대해 0차와 1차 연속성 조건을 각각 적용하여 구조해석을 수행하여 1차 연속성 조건의 주요한 특성들을 확인하였다. 또한 각 연속성 조건에 대한 해의 수렴 특성을 검토하였으며 결합 경계에서의 두 패치의 연속성을 확인하였다.

  • Background: Today, breast cancer is increasing in nearly all societies. Currently, cancers are the third leading cause of death in Iran after cardiovascular diseases and accidents. Of the cancers, breast cancer is spreading particularly rapidly among Iranian women. Negative effects of discontinuation of care on patient survival have been well documented. Inhibiting or facilitating factors affecting continuity of care at different stages of the patient care continuum should be identified. Materials and Methods: The current study implemented a qualitative method that provided tools to examine factors in detail. This study was conducted on 22 women, undergoing surgery and chemotherapy after being diagnosed with breast cancer. Content analysis was the technique adopted. Results: The effective factors in continuity of care from the patients' perception, based on the participant statements, were classified into three categories of evaluation of symptoms, psychological reactions, and care triggers with several subcategories. Conclusions: According to the outcomes of the current study, it can be noted that, the patient experiences can be brought into use by health-care professionals and assist them in providing patient sand their families with adequate consulting services. It can also provide an opportunity for making interventions tailored to the community culture, and closer adherence of patients to the prescribed treatments.

  • 본 연구는 2015 개정 교육과정의 총론의 중점 중 하나인 유치원 교육과정과 초등학교 교육과정의 연계 강화와 관련된다. 교육현장의 교사들이 교육과정보다 교과서에 더욱 의존적이라는 사실에 비추어 누리과정 교사용 지도서의 수학 활동과 초등 수학 교과서의 연계성을 분석하고, 그 결과에 기초하여 연계가 미흡한 내용에 대한 연계성 확보 방안을 제안하고자 하는 것이다. 이를 위해 구체적으로 누리과정 교사용 지도서와 초등 1, 2학년 수학 교과서를 수학 내용, 수학 용어와 기호, 수학적 과정의 세 가지 측면에서 비교 분석하였다. 본 연구의 분석대상은 3~5세 연령별 누리과정에 따른 교사용 지도서와 2009 개정 수학과 교육과정에 따른 초등학교 1, 2학년 수학 교과서이며, 본 연구와 동일선상에서 이루어진 누리과정과 초등학교 수학과 교육과정의 연계성 분석에 사용된 분석틀을 활용하였다. 각각에 대한 분석 결과를 제시하고, 그에 따른 논의로부터 양자 간의 연계성 확보 방안과 교육과정 개정 및 수학 교과서, 누리과정 교사용 지도서 개발에 있어서의 시사점을 제안하였다.

  • This study examined risk and protective variables related with the continuity of developmental risks among 136 infants, aged 4-10 months. Using the Denver Developmental Screening Test, 136 infants among 2978 infants in the first wave of the Korea Child Panel were classified into the developmental risk group. Among the 136 risk group infants, 45 infants stayed in the risk group (continuing risk group) and the other 91 infants moved into the normal group (recovering risk group) after 1 year. Group differences were tested in the levels of infant, mother and father variables to examine which variables were associated with the continuity of developmental risks for a year. Variables indicating parents' marital relationships such as the mothers' marital satisfaction and conflict of the first wave and the fathers' marital satisfaction of the second wave significantly distinguished the continuing from the recovering risk group. In addition, there were significant group differences in the levels of mothers' self-efficacy in the first wave. The findings suggest that the exposure to marital conflict during infancy is associated with the continuity of developmental risks.

  • Purpose: The purposes of this study were to develop a navigation program for newly diagnosed cancer patients and to evaluate its effects. Methods: The navigation program was based upon Professional Navigation Framework. Patients were asked to complete self-administered questionnaires on satisfaction, distress, anxiety and depression for evaluating the program. Results: The navigation program consisted of facilitating two concepts: continuity of care and empowerment of patients. Information-education package, telephone counseling and navigator's phone number were provided to the newly diagnosed cancer patients for care continuity. Self-care diary and emotional support by telephone counseling were provided to the patients for empowerment of patients. A total of 163 patients - 78 control and 85 experimental participants - were included in the study. The mean scores of satisfaction, distress, anxiety and depression had no statistical differences between the two groups after program implementation. In patients with longer waiting days, the experimental group with the navigation program showed higher relational continuity than the control group after program implementation(p=.023). In patients with longer waiting days or with higher distress, satisfaction of relational continuity was improved after program implementation in the experimental group. Conclusion: The navigation program in this study has applied the concept of patient navigation into oncology clinical setting in Korea. Navigation program can play a significant role in assisting patients navigating across the care continuum.

  • The objective of this paper is solving multidimensional backward stochastic differential equations with general time intervals, in Lp (p ≥ 1) sense, where the generator g satisfies a time-varying Osgood condition in y, a time-varying quasi-Hölder continuity condition in z, and its ith component depends on the ith row of z. Our result strengthens some existing works even for the case of finite time intervals.

  • Nonlinear ARMA model $X_n\;=\;h(X_{n-1},{\cdots},X_{n-p},e_{n-1},{\cdots},e_{n-p})+e_n$ is considered and easy-to-check sufficient condition for strict stationarity of {$X_n$} without some irreducibility or continuity assumption is given. Threshold ARMA(p, q) and momentum threshold ARMA(p, q) models are examined as special cases.

  • Let {X(t), $t{\geq}0$} be a stochastic integral process represented by stable random measure or multiple Ito-Wiener integrals. Under some conditions, we prove the continuity and self-similarity of these stochastic integral processes. As an application, we get Gaussian chaos which has some shift continuous function.
