Purpose : This scoping review was designed to identify gaps in knowledge and guide future directions for clinical nursing practices and research on oral hygiene care for endotracheally intubated patients in Korean intensive care units. Methods : We conducted a scoping review using the methodological framework proposed by Arksey and O'Malley. PubMed, CINAHL, RISS, Science On, and DBpia databases were searched. Two reviewers independently selected the studies and extracted data. A total of 445 studies were identified, of which 17 were included in the final analysis. Results : No research has been conducted from 2021 to the present. A total of 12 instruments were utilized in 13 studies to assess the effectiveness of oral hygiene care. All studies investigating the effectiveness of oral hygiene care have consistently documented that chlorhexidine has the most significant effect. The frequency and time of oral hygiene care were each examined in one study. Conclusion : A research study is necessary to develop a measurement tool for assessing the effectiveness of oral hygiene care suitable for endotracheal intubated patients in intensive care units. Interventional studies should be conducted to determine the effects of chlorhexidine and the appropriate frequency and time of oral hygiene care. Thereafter, revision of domestic evidence-based clinical practice guidelines by integrating these results will be necessary.

최근 골프는 많은 사람들의 취미 생활로서 자리를 잡아가고 있으며 골프와 관련된 연구도 다양하게 이루어지고 있다. 본 연구에서는 데이터 마이닝 기법을 사용하여 PGA 투어에 참여하는 선수들의 평균스코어를 예측하고 스코어에 유의한 영향을 미치는 변수들을 제시하고자 한다. 그리고 추가적으로 4개의 PGA 투어 플레이오프에 대해 상위 10명, 상위 25명의 선수들을 예측하는 것을 목표로 한다. 우리는 다양한 선형/비선형 회귀분석 방법을 이용하여 평균스코어를 예측하는데, 선형회귀분석 방법으로는 단계적 선택법, 모든 가능한 회귀모형, 라소(LASSO), 능형회귀, 주성분회귀분석을 사용하였으며 비선형회귀분석 방법으로는 트리(CART), 배깅, 그래디언트 부스팅, 신경망 모형, 랜덤 포레스트, 최근접이웃방법(KNN)을 사용하였다. 대부분의 모형에서 공통적으로 선택된 변수들을 살펴보면 페어웨이의 단단함와 그린의 풀의 높이, 평균최대풍속이 높을수록 선수들의 평균스코어는 높아지며 반대로 한 번에 퍼팅을 성공시키는 횟수와 그린적중률 실패 후 버디나 이글로 점수를 만드는 scrambling 변수들, 그리고 공을 멀리 보낼 수 있는 능력을 나타내는 longest drive는 그 값이 높아짐에 따라 선수들의 평균스코어가 낮아지는 경향이 있음을 알 수 있었다. 11가지 모형 모두 테스트 데이터인 2015년 경기 결과를 예측하는데 낮은 오류율을 보였으나 배깅과 랜덤 포레스트의 예측률이 가장 좋았으며 두 모형 모두 상위 10명과 상위 25명의 랭킹을 예측할 때 상당히 높은 적중률을 보였다. This study predicts the average scores of top 150 PGA golf players on 132 PGA Tour tournaments (2013-2015) using data mining techniques and statistical analysis. This study also aims to predict the Top 10 and Top 25 best players in 4 different playoffs. Linear and nonlinear regression methods were used to predict average scores. Stepwise regression, all best subset, LASSO, ridge regression and principal component regression were used for the linear regression method. Tree, bagging, gradient boosting, neural network, random forests and KNN were used for nonlinear regression method. We found that the average score increases as fairway firmness or green height or average maximum wind speed increases. We also found that the average score decreases as the number of one-putts or scrambling variable or longest driving distance increases. All 11 different models have low prediction error when predicting the average scores of PGA Tournaments in 2015 which is not included in the training set. However, the performances of Bagging and Random Forest models are the best among all models and these two models have the highest prediction accuracy when predicting the Top 10 and Top 25 best players in 4 different playoffs.

The safety of ICSI as a novel procedure of assisted fertilization may be assessed by the health of the baby born. In order to evaluate the safety of ICSI, perinatal outcome and congenital anomaly of the babies born after ICSI were compared with those of babies born after IVF (control group). We analysed the clinical data from the obstetric and pediatric records, including the information obtained through telephone. The results are as follows; Mean gestational age $({\pm}SEM)$ and birth weight in singleton pregnancy were $38.8{\pm}1.9$ weeks and $3209.7{\pm}501.9gm$ in IVF group, $39.0{\pm}2.2$ weeks and $3289.9{\pm}479.5gm$ in ICSI group, respectively. Mean gestational age and birth weight in twins were $36.8{\pm}2.1$ weeks and $2512.8{\pm}468.0gm$ in IVF group, $36.5{\pm}2.8$ weeks and $2492.7{\pm}537.1gm$ in ICSI group. In IVF group, perinatal mortality rates were 8.5 in singletons and 56.6 in twins; for the ICSI singletons and ICSI twins, the perinatal mortality rates were 11.6 and 49.0, respectively. The incidence of congenital malformations was 3.6% (8/224) in IVF group and 2.1% (4/188) in ICSI group, there was no statistical difference (p>0.05, Fisher's exact test). The incidence of major congenital anomalies was 0.9% (2/224; pulmonary artery hypoplasia, renal cystic dysplasia) in IVF group and 1.1% (2/188; holoprosencephaly, Cri du chat syndrome) in ICSI groups (p>0.05, Fisher's exact test). Similarly, there was no significant difference in incidence of minor congenital anormalies 2.7% (6/224) in IVF group and 1.1% (2/188) in ICSI group respectively (p>0.05, Fisher's exact test). In conclusion, there was no difference in the perinatal outcome and the incidence of congenital anomalies between the babies born after ICSI and those after conventional IVF.

무선 에드혹 네트워크에서 지역 기반 트리를 이용한 멀티캐스팅 프로토콜

임정은,유상조,Lim Jung-Eun,Yoo Sang-Jo 한국통신학회 2005 韓國通信學會論文誌 Vol.30 No.11B

본 논문에서는 무선 에드혹 네트워크에서 효율적인 데이터 전송을 위한 밀티캐스팅 프로토콜을 제안한다. 기존에 제안된 유무선망에서의 밀티캐스팅 프로토콜들은 이동성에 의한 망의 동적인 변화, 제한된 대역폭, 높은 에러율등의 특성을 지닌 무선 에드혹 네트워크 환경을 고려하지 못하여 이를 그대로 무선 에드혹 망에 적용할 경우 나쁜 성능을 보인다. 이를 해결하기 위하여 에드혹 네트워크 환경을 고려한 멀티캐스팅 프로토콜들이 제안되었다. 그러나 이들 프로토콜 또한 제어메시지 오버헤드와 대역폭의 낭비를 줄이는 동시에 높은 데이터 전달률을 제공하지는 못하고 있다. 따라서 본 논문에서는 이를 개선한 지역 기반 트리를 이용한 멀티캐스팅 프로토콜(RTMA)을 제안한다. 지역 기반 트리를 이용한 멀티캐스팅은 위치 정보를 이용하여 지역을 나누어 지역 별로 트리를 구성한다. 이것은 송신자의 수가 많은 경우에도 제어 메시지의 오버헤드를 줄이는 동시에 효율적인 데이터 전송을 위한 것이다. 또한 이동성에 대처하지 못하는 트리 구조의 특성을 보완하기 위하여 속도정보를 이용하여 이동성이 큰 노드를 경로에서 제외시켜 신뢰성 있는 트리를 구성한다. In this paper, we propose an effective multicasting protocol in wireless ad-hoc networks. Conventional wired and wireless network multicast protocols do not perform well in wireless ad hoc networks because they were designed without consideration of ad hoc environments such as node mobility, limited bandwidth, high error probability. To solve this problem, some multicasting protocols for ad hoc network have been proposed in the literature. However, these protocols can not provide high packet delivery ratio, low control packet overhead and low expended bandwidth at the same time. Therefore, in this paper, we propose RTMA that improves multicasting performance in wireless ad hoc networks. RTMA calculates its current region from its position information by using GPS in order to make tree among the multicast group nodes in the same region. The proposed region-based tree method is for high packet delivery ratio, low control packet overhead when many senders send data packets. RTMA makes a reliable tree by using speed information to fill a gap of the weak points of the tree structure. When searching the routing path, RTMA selects the reliable path excluding high speed nodes.

본 연구는 오염토양 정화 및 폐자원의 재활용 측면에서 굴껍질 및 달걀껍질을 활용한 비소 오염토양 안정화 기술의 적용 가능성을 평가하고자 수행되었다. 안정화 효율을 평가하고자 5가비소로 오염된 토양에 굴껍질과 달걀껍질을 0%(무처리구)~5% 수준으로 처리한 후 30일간 항온배양 하였으며 이후 1 N HCl, 0.1 N NaOH, 0.5 N H₂SO₄의 추출제를 이용하여 토양 중 비소를 추출하였다. 1 N HCl 추출결과 무처리구의 비소 함량은 29.43 mg/kg였고 굴껍질 5% 및 달걀껍질 5% 처리구에서 각각 26.26 mg/kg와 26.74 mg/kg로 나타나 평균 10% 정도로 감소효과를 나타내었다. 이외 0.1 N NaOH 및 0.5 N H₂SO₄ 추출결과에서도 비소의 농도는 소폭 감소하였다. 한편 굴껍질 및 달걀껍질 처리 토양의 pH는 7.62~7.94로 무처리구 (pH 6.54)에 비해 pH 1 이상 증가하였고, 토양 내 치환성 칼슘의 함량은 12.77~20.18 cmol(+)/kg로 무처리구(6.87 cmol(+)/kg)보다 약 2배 이상 증가하는 것으로 나타나 굴껍질과 달걀껍질은 토양 비옥도 개선에 효과가 있는 것으로 판단되었다. 이상의 결과를 종합해보면 굴껍질과 달걀껍질의 직접적 사용은 토양의 비옥도 향상에는 효과가 있는 것으로 판단되나 토양내 비소의 안정화에 적용하기에는 다소 부적합한 것으로 판단되며 향후 효율성 향상을 위하여 소성과 같은 적절한 가공 공정이 필요한 것으로 판단되었다. The objective of this research was to evaluate the feasibility of using oyster-shell and eggshell wastes for the stabilization of arsenic-contaminated soil. Artificial As(V) contaminated soil was mixed with 0~5% oyster-shell and eggshell wastes and each sample was incubated for 30 days in a controlled environment. The efficiency of each treatment was evaluated using various single extractants (1 N HCl, 0.1 N NaOH and 0.5 N H₂SO₄). The concentration of As(V) was reduced by 10% upon a 5% oyster-shell or eggshell waste treatments based on the Korea Standard Test method (1 N HCl extraction). Analogous trends were observed in the 0.1 N NaOH or 0.5 N H₂SO₄ extractions. In addition, the oyster-shell and eggshell waste treatments increased the pH of each soil from 6.54 (Control) to 7.62~7.94. The exchangeable Ca in each soil also sharply increased from 6.87 cmol(+)/kg (Control) to 12.77~20.18 cmol(+)/kg. Further research is needed to increase the effectiveness of the oyster-shell and eggshell waste for the stabilization of As(V) in the contaminated soil.

This study was conducted to evaluate the effects of reduced nitrogen (N) and potassium (K) fertigation as additional fertilizer on tomato yield and nutrient contents in excessively nutrients-accumulated soil. Shoot and root dry weights (DW), dry matter rate for shoot, root and fruit and number of fruit in both AF50 and AF100 (50 and 100% levels of additional fertilizer) treatments were increased in comparison with those in AF0 (0% level of additional fertilizer) treatment. In case of nutrient uptake by tomato, nitrogen, phosphorous (P) and potassium contents in all tomato parts (leaf, stem, root and fruit) in AF50 and AF100 treatment were lower than those in AF0 treatment. On the contrary, soluble sugar and starch contents in all tomato parts in AF50 and AF100 were higher than those in AF0 treatment. There were differences between AF0 and AF50 or AF100 in tomato growth, yield, nutrient level and contents of soluble sugar and starch. In contrast, the level and initiation point of fertigation did not significantly affect the parameters. Based on our results, the application of properly reduced level of additional fertilizer is possible to maintain the productivity of tomato and alleviate the nutrient accumulation in plastic film house soils.
