Purpose: This study aimed to develop a bedside nursing shift report protocol and evaluate the effect of the protocol in a tertiary hospital in South Korea. Methods: The bedside nursing handoff protocol with patient engagement was developed based on the literature review and the validation of an expert group. The effect of the protocol on clinical implication was tested in three medical-surgical units in a tertiary hospital. Outcomes were assessed by patient perception, nurse perception, and reporting time. Data collected from June to August in 2018 and analyzed with descriptive statistics and One-way ANOVA using SPSS version 25.0. Results: The bedside nursing shift report protocol with patient engagement consisted of two steps: nurse to nurse report and bedside report with patients. Nurse's perception with patient engagement was significantly increased after applying protocol (F=17.85, p<.001). Patient's perception was significantly improved in the areas of discharge plan (F=7.86, p<.001), health information privacy (F=4.46, p=.012) and identify attending nurse (F=3.19, p=.042). There were no differences in reporting time between the bedside nursing shift report and a traditional shift report (F=0.61, p=.054). Conclusion: Patient perception was significantly increased, while nurse perception was not different after applying this protocol. For the change in the perception of nurses, education may be preceded to improve nurses' competence for the bedside shift report. Furthermore, the support in enough nurse staffing should be needed for encouraging the bedside shift report. The bedside shift report may enhance patient engagement. Therefore it may improve patient safety and health outcome in clinics.

The purpose of this study is to provide the justification of the subject through review and alternatives example on the internal consistency of Home Economics curriculum components focused to the clothing & textiles area based on the beliefs and values inherent in the Home Economics curriculum. For this purpose, we examined the perspective of the assumptions about the five components of the curriculum - family, society, objective, subject matter, method in education - from the revised curriculum in 2007 to in 2015, and suggests an example of subject matter based on the result. The results of this study are summarized as follows. First, the clothing & textiles area of the revised curriculum from in 2007 to in 2015, family, society, objective, subject matter and method in education, excluding subject matter, were taken from a critical science perspective. In order for Home Economics curriculum components to be internally consistent, assumptions about the subject matter should be transformed to deal with the clothing & textiles as a family work. And needed to complement assumptions about family, objective and method in education. Second, based on the discussion, suggested an alternative example to the clothing & textiles area based on the internal consistency of Home Economics curriculum components.

This study was conducted to increase grape quality by treating plant growth regulator (PGR) in 'Campbell Early' grape. Foliar application of gibberellic acid ($GA_3$) at $5mg{\cdot}L^{-1}$ on flower cluster of 'Campbell Early' grape at 3-5 unfolded leaf stage effectively increased columella length, berry weight, soluble solid contents and promoted skin color development. Foliar application of $20mg{\cdot}L^{-1}$ abscisic acid (ABA) mixed with $5mg{\cdot}L^{-1}$ of $GA_3$ on flower cluster of 'Campbell Early' grape at 3-4 unfolded leaf stage effectively increased skin anthocyanin contents without any detrimental effects on berry enlargement and columella growth. Foliar application of $2.5mg{\cdot}L^{-1}$ thidiazuron mixed with $5mg{\cdot}L^{-1}$ of $GA_3$ on flower cluster of 'Campbell Early' grape at 3-4 unfolded leaf stage effectively increased fruit quality indices such as higher soluble solid contents and less titratable acidity.

Silicon solar cells have been widely used as a most promising renewable energy source due to eco-friendliness and high efficiency. As modules of silicon solar cells are connected in series for a practical electricity generation, a large voltage of 500-1,500 V is applied to the modules inevitably. Potential-induced degradation (PID), a deterioration of the efficiency and maximum power output by the continuously applied high voltage between the module frames and solar cells, has been regarded as the major cause that reduces the lifetime of silicon solar cells. In particular, the migration of the $Na^+$ ions from the front glass into Si through the anti-reflection coating and the accumulation of $Na^+$ ions at stacking faults inside Si have been reported as the reason of PID. In this research, the thickness effect of $SiO_x$ layer that can block the migration of $Na^+$ ions on the reduction of PID is investigated as it is incorporated between anti-reflection coating and p-n junction in p-type PERC solar cells. From the measurement of shunt resistance, efficiency, and maximum power output after the continuous application of 1,000 V for 96 hours, it is revealed that the thickness of $SiO_x$ layer should be larger than 7-8 nm to reduce PID effectively.

We present a quantitative evaluation of density, vesicularity and microtextures for coarse lapilli collected from the Jugam Scoria Deposits, northeastern Ulleung Island. Lapilli from the deposits have modal vesicularities of 61% in the lower part and 67% in the upper part, and vesicle populations dominated by non-interconnected subround vesicles. Clasts of modal vesicularity have margin-parallel zonation, with subaerially quenched rims interpreted to preserve "syn-fragmentation" magmatic textures in microlite-free sideromelane rims, grading "post-fragmentation" tachylitic interiors with vesicle and microlite textures that progressively coarsen from rim to interior. Degassing scenarios are linked to syn-fragmentation vesicle textures to demonstrate that the magmas degassed in dominantly closed systems. And diffusion-controlled cooling rates of trachyandesitic pyroclasts in contact with atmosphere are linked to post-fragmentation evolution of vesicle and microlite textures to infer about transportation and dispersal of the pyroclasts in low shooting jets. These textural analyses show that the Jugam eruptions were strictly applied to the strombolian type, analogous to the hawaiian type among any classical subaerial eruption type.

일반적인 다목적댐은 홍수 발생 시 본댐으로 유입되는 부유쓰레기 및 잡목 등을 차단하기 위하여 댐 상류에 차단망을 설치하여 1차적으로 사전 방지하고, 홍수기 이후 선박으로 부유물을 수거하여 재활용, 소각 등으로 처리하는 시스템이다. 그러나 본 연구의 대상인 한탄강댐은 홍수조절용 댐으로서 수위 변화 폭이 매우 크고 정상 조건(비 홍수기)시는 대규모 홍수터가 드러나기 때문에 댐 유지관리 방법이 상이하며 한탄강 본류 구간은 하폭과 수심 등 하도의 불규칙성과 만곡부에서 유수의 흐름이 한쪽으로 쏠리는 편기 현상이 발생하는 등 복잡한 수리현상으로 인하여 부유쓰레기의 분포를 판단하기 어려운 지역이다. 따라서 본 연구에서는 부유쓰레기의 유동을 모의하기 위하여 HEC-HMS 모형과 $Vflo^{TM}$ 모형을 활용하여 본류와 지류의 빈도별 홍수량 분석을 실시하고, EFDC 3차원 동수역학 모형을 적용하여 홍수조절용지 내 부유쓰레기의 유입 경로 및 정체 구역을 분석하여 효과적인 쓰레기 처리 방안을 제시하고자 하였다. 분석 결과, 소규모 빈도 홍수(2년, 5년)의 경우 중 상류 지류의 부유쓰레기는 거의 유동하지 못하고 하도의 만곡의 영향을 받아 부분적으로 높은 밀도로 고착될 것으로 모의되며, 특히 본류와의 합류점 부근에 도달한 부유쓰레기는 유로 폭이 급확대되어 유속이 거의 없는 사수역 구간으로 변함에 따라 본류 배수위 영향으로 불규칙하게 맴돌다가 고착되는 것으로 모의되었다. 중규모 홍수(25년, 50년)의 경우, 상류부의 부유쓰레기의 분포는 소규모 홍수 시와 유사한 패턴을 보였으나 중류부에서 홍수파가 본류 하도를 월류하여 홍수터로 넓게 범람하는 지역에서는 소규모 홍수 시 본류 하도 양안에 분포하던 부유쓰레기가 홍수터 쪽으로 밀려가서 고착되는 경향을 보였다. 대규모 홍수(100년, 200년)의 경우, 댐과 인접한 분석 구간 하류부는 댐 배수위의 영향을 가장 크게 받으며 수심이 깊어 흐름이 가장 정체되는 구간으로 본류와 지류 모두 다량의 부유쓰레기가 분포할 것으로 분석되었다. 분석 구간 중류부는 홍수 규모가 증가함에 따라 넓은 홍수터로 침수범위가 급격하게 증가하며 이에 따라 부유쓰레기가 분포할 수 있는 면적이 크게 증가할 것으로 분석되었다. 또한 분석 구간 상류부는 협곡을 이루고 있어 홍수규모가 증가하더라도 침수범위와 부유쓰레기의 분포면적에 큰 변화가 없을 것으로 분석되었다. 본 연구 결과를 바탕으로 댐의 치수 문제가 발생하지 않도록 효과적으로 수거 처리 할 수 있는 부유쓰레기 적치장 및 차단 시설의 적정 설치 위치를 파악하였다.

Bone and soft tissue conditions are important for successful implant treatment. But, the placement itself is also very important. Implants which is installed in the wrong position result in the biological, esthetical and mechanical problems. In order to place an implant in the correct position, the final restoration and diagnostic wax-up should be considered prior to the surgery. If the artificial teeth for the interim denture are directly transferred from the diagnostic wax-up, the operator can try the form of diagnostic wax-up in the mouth. If the surgical template is produced by duplicating the interim denture, the implant can be placed in the planned position. In this case, the polymethyl methacrylate (PMMA) artificial tooth was precisely milled by the digital duplication of diagnostic wax-up. And interim denture was fabricated by using these milled teeth. After the patient adapted for a sufficient period, the implant was placed at the planned position with surgical template produced by duplicating the interim denture. After confirming sufficient osseointegration, the final prostheses were made to reflect the shape of diagnostic wax-up. Through this procedure, the satisfactory functional and esthetic outcome could be acquired.

A conventional approach for the treatment of long-span edentulous areas is the use of removable dentures. However, placing implants in these areas results in superior functional outcomes by increasing the stability, support, and resistance of the prostheses and improving the masticatory efficiency. Treatment modalities utilizing implants can be further classified into either removable or fixed-type prostheses. Several factors such as the amount of alveolar bone resorption, inter-arch relationship, patient preferences, and socioeconomic status should be considered when determining the appropriate treatment approach. Monolithic zirconia has been considered a suitable material for implant-supported fixed dental prosthesis, because of the drastic improvement in its mechanical properties. It exhibits fewer incidences of fracture and chipping of the prostheses, and has greater bulk of material than metal-ceramic crowns and zirconia-veneered ceramics. Moreover, highly translucent monolithic zirconia is also available in the market, and its application is gradually increasing for anterior tooth rehabilitation. The present report describes a patient who underwent full-mouth rehabilitation with fixed dental prostheses (eight upper and three lower implant placements). All teeth, except bilateral mandibular canines and left mandibular first and second premolars, were extracted after the diagnosis of generalized chronic moderate-to-advanced periodontitis of the remaining teeth. The patient reported satisfactory esthetic and functional outcomes during the one-year follow-up visit.
