Purpose: The purpose of this study was to provide evidence for future research by analyzing the contents, delivery methods, and educational effects of educational programs for hemodialysis patients. Methods: A literature review was conducted in the following order: problem identification, literature search and data collection, data evaluation, data analysis, and data presentation. In total, 936 documents were retrieved from the search, and 24 documents were finally included in this study. Results: The contents of the educational programs were comprehensive hemodialysis-related knowledge education in seven studies, exercise-related education in 10 studies, diet-related education in four studies, drug-related education in one study, and complex education in two studies. The delivery methods were pamphlets in six studies, audio-visual materials in four studies, direct guidance by researchers in six studies, and multiple methods in seven studies. The effects of the educational program were divided into physical indicators, emotional indicators, and knowledge and performance related to hemodialysis. Sixteen out of 20 articles using physical indicators showed significant outcomes, and 10 out of 12 articles using emotional indicators derived positive results. Hemodialysis-related knowledge and performance were measured in eight and 10 studies, respectively, and meaningful results were found in six studies for knowledge and seven studies for performance. Conclusion: Future research will require the development of a systematic and standardized educational program with comprehensive content that can be provided to all hemodialysis patients, as well as a highly accessible education delivery method to enhance the effectiveness of education.

This study investigated the correlation between the level of consistency in fashion show models' appearance and design concept through a statistical and qualitative analysis of the S/S Paris Collection 2014. The following conclusions have been drawn in this study. First, the percentage of models of color was very low in regards to the physical appearance of models; in addition, there was a higher percentage of Caucasian models for collections with a high level of consistency in models' physical appearance. Collections with a high percentage of models of color indicate more casual design concepts and the promotion of diversity in racial background is considered more effective for street fashion. Second, collections with a high level of consistency in models' physical appearance tend to control various elements that constitute a physical appearance through more detailed planning and stage direction. Third, there is a tendency to reinforce design concepts by creating a consistency in the overall physical appearance of models. This affirms that their physical appearance is determined by brand (i.e. designer) and is used to maximize a design concept delivery. The results of this study suggests that the physical appearance of models must be determined in line with the design concept versus detailed planning that must consider audience perspectives as well as adjust the show's length and the interval between each model appearing on the stage.

본 연구는 체내, 체외 및 복제를 통하여 각각 생산된 배반포를 이식하여, 수란우의 수태율, 임신기간 및 유산율과 더불어 송아지의 생시 체중과 이후 생존율을 조사하였다. 그 결과, 수태 을은 체내수정란이 56.3%로서 복제 수정란의 19.4%에 비하여 유의하게 높았으나 (p<0.05), 체외수정란의 30.0%와는 유의성이 인정되지 않았다 유산율과 임신기간은 처리군 간에 유사한 경향이었다(유산을 0, 22.2 및 16.7%; 임신기간 278.8, 289.4 및 281.4일). 한편 송아지의 체중은 복제수정란에서 유래된 송아지의 평균 39.9kg은 체내수정란에서 유래된 송아지의 평균 25.5kg에 비하여 유의하게 높았다.(p<0.05). 체내수정란이 수태된 수란우(n=9)는 모두 정상 분만하였으며, 그 송아지 는 생후 60일령까지 모두 생존하였다. 한편 체외수정란이 수태된 수란우(n=7)도 모두 정상 분만하였으나, 그 송아지 가운데 1두는 생후 48일에 사망하였다. 복제 수정란이 수태된 수란우(n=5)는 정상 분만 3두 및 제왕절개 2두를 하였다. 정상 분만된 복제송아지(n=3) 중에서 2두는 분만 직후 사망하였으나, 제왕절개로 태어난 송아지는 생후 60일까지 모두 생존하였다.

본 연구에서는 유량 및 유사량 자료가 부족한 미계측 유역에 대해 Tank모형을 확장하여 궁극적으로 유사량을 평가하는 방법을 제시하였다. 적용 유역은 동해안 타 유역에 비해 유량자료가 확보되어 있는 오십천을 대상으로 집중호우기의 토사유출 특징과 하천의 토사유달률을 구하였다. 본 연구의 주요 결과는 다음과 같다. 1) 실측에 의한 유사량의 산정에 있어서는 먼저 유사량 관계식(sediment rating curve)의 개발이 선행되어야 한다. 본 연구에서는 유량 산정지점에 대해 유량과 병행하여 유사량 관계식을 다음과 같이 구하였다. 오십천 유량-유사량 관계식 : $Q_s=6.017Q^{1.374}$ 2) Tank모형을 적용하여 2006년 강우유출량을 산정한 결과 관측값과 유사한 값($RMSE=1.26m^3/day$)을 얻을 수 있었다. 3) 대상지역의 2006년과 2009년의 연평균 토사전달율 을 비교한 결과 태풍에 따른 집중강우가 있었던 2006년의 토사전달율이 평년의 2009년에 비해 현저하게 높았는데 이는 급격한 강우유출량의 증가에 따른 것이라 보인다. 4) 개량된 Tank모형에 의한 유량 및 토사유출량은 기존의 SRC방법과 비교했을 경우 유사한 경향을 보였으며 이는 향후 유량과 유사량 자료가 부족한 유역에 대해 효과적으로 적용할 수 있을 것으로 본다.

Unmanned aerial vehicles are gaining in popularity with the development of science and technology, and are being used for a wide range of purposes, including surveillance, rescue, delivery of goods, and data collection. In particular, the ability to avoid obstacles during navigation without human oversight is one of the essential capabilities that a drone must possess. Many works currently have solved this problem by implementing deep reinforcement learning (DRL) model. The essential core of a DRL model is reward function. Therefore, this paper proposes a new reward function with appropriate action space and employs dueling double deep Q-Networks to train a drone to navigate in indoor environment without collision.

The purpose of this study was undertaken to determine the nursing need of mother herself and her baby in puerperium period at home alone with percevied her role. It was hoped that this nursing information would help nurses plan effective for their nursing care. This study involved 100 postpartum mothers and the period for data collection was from May to July, 1982. The results of study were as follows; 1. The mother's mean age of 27.45, more than half of mother's was high school graduate, most of the mother have their religion, 78.4％ was housewives, and 21.6% have occupation, Their mean marriage period was 30.2 years, 61% was nuclear family with 4.2 family members and primipara was higher then multipara. 2. Most mothers showed that positive attitude for their delivery and perceived higher their mother's role. 3. Mother showed more nursing need about infant（for example, bathing, meaning of crying) than herself. 4. There was a positive correlation between mother's education, wether or not their occupation, marriage periode, parity and mother's role and their nursing need.

Power system technologies in the area of smart grid are being converged with communication system technologies or information technologies(IT). This interdisciplinary action affects on two parts vigorously so that IT has become a essential part of power industry. But terminologies of two parts are confused and it is necessary that these are standardized to develop the industry. The interpretation works with scientific and technological standard of the smart grid terminologies which are IEC TC 57 glossary and non-glossary terminologies are introduced. Based on the interpretation works of the smart grid terminologies, an online terminology information system for the standardization of smart grid terminologies is proposed. The system provides the capability of collection and delivery of academic society opinions for the selected and interpreted terminologies.

This study was undertaken to determine .the identify the relation between the high risk mother and their baby which then allows the nurse to assess and plen for the delivery of optimal health care to the high risk groups. This study was carried out between January through December 1978. This study sample consisted of 300 pregnant women who visited Ewha womens hospital during this time. The method used to for the collection of data was an“Antepartum High-risk pregnancy scoring form. The questionair included 4 categories: 1) reproductives history 2) Associated conditions 3) pre-sent pregnancy and 4) total risk score . The bind are as follows: 1. The frequency of high risk pregnancy women 149(49.7%) was highest. 2. In the investigation sample high risk factors were related to hypertension and toremia. 3. There was a difference in the high risk scores and newborn babys scores (r = 0.610). 4. Relationship between high risk pregnancy women and least of pregnant women was highest prenatal mortality. Implications of positive assessing of high risk factors by MCH nurse and community health nurses.
