Purpose: The purpose of this study was to investigate the knowledge and educational needs of nurses and physicians on home ventilator. Methods: The participants were 140 nurses and 47 physicians working at departments using home ventilators. The data were collected from January 30 to February 12, 2012 through a self-administered questionnaire with 32 items of the knowledge and educational needs on home ventilator. Results: The mean scores of nurses' and physicians' knowledge were 2.52 and 2.56 respectively. The mean scores of nurses' and physicians' educational needs were 3.16 and 3.06 respectively. Nurses' knowledge was associated with their experience using and receiving education about home ventilator and willingness to receive education about home ventilator education. Nurses' educational needs were associated with their present working department and experience using home ventilator. Nurses with high knowledge were more likely to have high educational needs. Physicians' knowledge and educational needs were not associated with any their general characteristics. Conclusion: Nurses' and physicians' knowledge of home ventilator were low and their educational needs on home ventilator were high. To provide high quality of care for home ventilators, it is necessary to provide nurses and physicians with education and to develop a more specific educational program for them.

Purpose: The purpose of this study was to determine the difference in reported discharge learning needs between nurses and liver transplantation (LT) patients. Methods: The participants of this study were 40 patients discharged after LT at P University Hospital in Y City and 42 nurses in intensive care units and the ward. The data were collected for two months from December 1, 2012, to January 31, 2013, and were analyzed using descriptive statistics, Student's t-test and analysis of variance (ANOVA). Results: Patients earning a low income (p=.041), having no experience of hospitalization after LT (p=.023), and receiving information about LT from nurses (p=.003) indicated higher discharge learning needs. Among the items evaluated regarding discharge learning needs, "rejection symptoms or signs" were regarded to be more important by nurses than LT patients (p=.038). However, "management of other diseases after LT" (p=.003), "risk of recurrence" (p=.001), "food choices" (p<.001), "obesity prevention" (p=.020), "amount of exercise" (p=.007), and "ways to receive financial help"(p=.033), were thought to be more important by LT patients than nurses. Conclusion: There exist differences between LT patients and nurses with respect to their perceptions of LT discharge learning needs. Therefore, an individualized education program reflecting patients' conditions and learning needs rather than providing information uniformly needs to be developed.

This paper introduces an effective system design method to develop a customer oriented product using a design optimization process and to select a set of critical design paramenters,. The process results in the development of a successful product satisfying customer needs and reducing development risk. The proposed scheme adopted a five step QFD(Quality Function Deployment) in order to extract design parameters from customer needs and evaluated their priority using risk factors for extracted design parameters. In this process we determine critical design parameters and allocate them to subsystem designers. Subsequently design engineers develop and test the product based on these parameters. These design parameters capture the characteristics of customer needs in terms of performance cost and schedule in the process of QFD, The subsequent risk management task ensures the minimum risk approach in the presence of design parameter uncertainty. An application of this approach was demonstrated in the development of weld quality monitoring system. Dominant design parameters affect linearity characteristics of weld defect feature vectors. Therefore it simplifies the algorithm for adopting pattern classification of feature vectors and improves the accuracy of recognition rate of weld defect and the real time response of the defect detection in the performance. Additionally the development cost decreases by using DSP board for low speed because of reducing CPU's load adopting algorithm in classifying weld defects. It also reduces the cost by using the single sensor to measure weld defects. Furthermore the synergy effect derived from the critical design parameters improves the detection rate of weld defects by 15% when compared with the implementation using the non-critical design parameters. It also result in 30% saving in development cost./ The overall results are close to 95% customer level showing the effectiveness of the proposed development approach.

Purpose : The purpose of this study was to not only examine the importance and performance status of patient safety nursing activities in the intensive care unit but also to understand nurses' educational needs in this respect. Methods : In this descriptive study, 196 nurses working in the intensive care units of university hospitals located at B City and G Province were enrolled. They completed the Importance-Performance Analysis (IPA) questionnaire, and the data were statistically analyzed. Results : Mean±standard deviation item scores of importance and performance of patient safety nursing activities were 4.75±0.33 and 4.48±0.38, respectively. In the IPA results, a total of 10 items were included in the second quadrant, including 1 item related to 'transfer,' 1 to 'infection,' and 1 to 'firefighting surveillance.' As the second quadrant contains the high-importance, low-performance items, these 10 items resemble the nurses' educational needs that should be prioritized. Conclusion : The results of this study can be used as a basis for the development of nursing educational programs for patient safety in the intensive care unit.

When teaching English in elementary schools was introduced in Korea in 1997, the theoretical basis was the critical period hypothesis (CPH). The object of this study was to test whether the Korean situation satisfies the conditions for the CPH such as the amount of English input and needs. As a test for this, English input and needs were compared in Korea, the U.S.A. and Singapore. The items for English input were on a continuum of primary to secondary sources and the items for English needs were on a continuum of immediate to future needs. The 0-5 scale was used. The result showed that the total means of English input were 4.87, 4.62, and 1.05 for children in the U.S.A., Singapore and Korea respectively. The total means of English needs were 4.32, 3.81, and 1.52 for children in the U.S.A., Singapore and Korea respectively. These figures show that Korean children's levels of both input and needs were from “almost none” to “little,” while those of children in the U.S.A. and Singapore were from “much” to “very much.” This shows that teaching English in Korea presently is far from meeting the conditions that are expected by the CPH. As an alternative to explain what happens cognitively to Korean children, this paper suggests the automatization and proceduralization processes.

Purpose : This study sought to investigate novice nurses' communication education needs in the intensive care unit (ICU) using Importance-Performance Analysis (IPA) and Borich's need assessment model. This study identified communication challenges in clinical settings to develop a simulation program that enhances communication competencies based on educational requirements. Methods : A descriptive research design and a self-report questionnaire were used. The latter was developed and administered to 121 novice nurses with less than one year of experience in the ICU at various university hospitals in Korea. Data were collected via the online open chatroom from June 24th to July 28th, 2023. The communication education needs were identified using descriptive statistics, t-tests, IPA, and Borich's needs assessment model. Text analysis was used to categorize the participants' communication experience. Results : The results revealed that "communication with physicians," "communication with patients," and "communication with nurse on another shift" domains contained the most substantial educational needs for novice nurses working in the intensive care units. Conclusion : The results provide fundamental data for developing and enhancing customized communication education programs for novice ICU nurses. This valuable information could help ICU nurses and educators improve new nurses' communication skills, which would ultimately contribute to the advancement of nursing education and clinical practice.

디지털 신호 처리 분야에서 디지털 필터는 필수불가결한 요소이다. 디지털 필터는 이진수의 곱셈 및 덧셈을 기본으로 하는 것으로 많은 연산량을 필요로 한다. 디지털 필터 내의 곱셈기는 VLSI 기술을 이용한 디지털 필터의 설계에 있어 반도체 칩 내부의 넓은 영역을 차지하고 전력의 대부분을 소비하며, 필터의 critical path를 결정하여 필터의 성능을 결정하는 중요한 요소로서 작용 한다. 본 연구에서는 특히 디지털 필터의 복잡성(complexity)를 해소하고 critical path를 줄여 필터의 연산속도를 증가시키기 위한 방법으로 2의 보수로서 표현되는 이진수를 CSD(canonical signed digit)와 MSD(minimal signed digit)로 동시에 변환하여 표현하는 방법을 제안하였다. 제안된 방법은 VHDL로 구현하고 임의의 필터에 적용하여 필터의 critical path가 감소하는 것을 보였다.
