Objectives: This study was performed to identify factors related to perceived health status among patients with type 2 diabetes. Methods: This is cross-sectional observational study. Respondents were 106 visitors in an outpatient diabetes clinic of a university hospital. Self-report questionnaire which included general information inquiry, diabetes-related, sociopsychological factors, functional health literacy and perceived health status was used for this study. The data was analyzed by using descriptive statistics, independent simple t-test, one-way ANOVA, and hierarchical multiple linear regression. All analysis were conducted using SAS 9.3. Results: Among the respondents, 43.4% engaged in poorly perceived health status. After adjusting for control variables, functional health literacy is significantly related to perceived health status(${\beta}$=0.095, p=0.016). Conclusion: Independent of diabetes-related, sociopsychological factors, higher functional health literacy is associated with better perceived health status of patients with type 2 diabetes. In order to improve perceived health status in the type 2 diabetes patients, it is necessary to develop strategy to enhance the functional health literacy.

This paper presents a novel approach to design evaluation of portable consumer electronic (PCE) products using augmented reality (AR) based tangible interaction and functional behavior simulation. In the approach, the realistic visualization is acquired by overlaying the rendered image of a PCE product on the real world environment in real-time using computer vision based augmented reality. For tangible user interaction in an AR environment, the user creates input events by touching specified regions of the product-type tangible object with the pointer-type tangible object. For functional behavior simulation, we adopt state transition methodology to capture the functional behavior of the product into a markup language-based information model, and build a finite state machine (FSM) to controls the transition between states of the product based on the information model. The FSM is combined with AR-based tangible objects whose operation in the AR environment facilitates the realistic visualization and functional simulation of the product, and thus realizes faster product design and development. Based on the proposed approach, a product design evaluation system has been developed and applied for the design evaluation of various PCE products with highly encouraging feedbacks from users.

Non-Functional Requirements (NFR) play a crucial role during the software development process. Currently, NFRs are considered more important than Functional Requirements and can determine the success of a software system. NFRs can be very complicated to understand due to their subjective manner and especially their conflicting nature. Self-adaptive systems (SAS) are operating in dynamically changing environment. Furthermore, the configuration of the SAS systems is dynamically changing according to the current systems context. This means that the configuration that manages the trade-off between NFRs in this context may not be suitable in another. This is because the NFRs satisfaction is based on a per-context basis. Therefore, one context configuration to satisfy one NFR may produce a conflict with another NFR. Furthermore, current approaches managing Non-Functional Requirements trade-off stops managing them during the system runtime which of concern. To solve this, we propose fragmentizing the NFRs and their alternative solutions in form of Multi-entity Bayesian network fragments. Consequently, when changes occur, our system creates a situation specific Bayesian network to measure the impact of the system's conditions and environmental changes on the NFRs satisfaction. Moreover, it dynamically decides which alternative solution is suitable for the current situation.

본 논문에서는 순수 함수형 언어로 작성된 쌍방시뮬레이션 알고리듬의 성능을 멀티코어 프로세서 컴퓨터에서 병렬화로 향상시키는 방법을 연구한다. 이 병렬화에 있어 핵심 아이디어는 순수 함수형 프로그램의 참조 투명성을 십분 활용하면 병렬화가 전혀 고려되지 않고 작성된 초기 구현으로부터 최소한의 수정만으로 성능 개선 효과를 기대할 수 있다는 것이다. 초기 구현과 병렬화 구현 둘 다 순수 함수형 언어인 하스켈로 작성되었다. 초기 구현을 병렬화할 때 변화는 아주 적어서 병렬화된 구현에서도 초기 구현의 프로그램 구조가 거의 그대로 유지되었다. 벤치마크를 통해 제시된 간단한 병렬화만으로도 초기 구현과 비교해 두 배 이상의 성능 개선을 확인했다. 또한, 병렬화와는 별개의 최적화 기법인 메모이제이션이 적용된 버전의 쌍방시뮬레이션 구현에도 같은 방식의 병렬화를 적용함으로써 마찬가지로 성능을 개선할 수 있음을 확인하였다.

Background: Cancer affects patients in many ways including physical, social, emotional, psychological and economic and restricts the functional lives. Psychiatric problems seen among cancer patients may increase the suicide probability and patients perceive suicide as a peaceful death type. The aim of this study was to examine the correlation between functional life and suicide probability among cancer patients. Materials and Methods: This study was conducted with 105 cancer patients as descriptive. The Functional Living Index_Cancer (FLIC)," suicide probability scale" (SPS) and personal information form were used as data collecting tools. Data were evaluated by descriptive analysis, and Pearson's correlation. Results: It was determined that 34.3% of patients thought of suicide. Significant negative correlation was found between functional life and suicide probability (r=-.641, p=0.000), increase being evident in those with poor functional life. Conclusions: It is recommended that cancer patients should be supported for improving their functional lives with help in coping processes for illness and treatment symptoms. Evaluation of the patient mental status to prevent the suicide among this group is an important role for nurses.
