Purpose: The purpose of this study is to reduce loneliness through a systematic review by analyzing the effectiveness, composition and method of non-face-to-face services on the elderly living in the local community. Methods: From June 11 to 15, 2021, related papers were searched using six databases: Ovid-Medline, Ovid-Embase, Cochrane library, KISS, Koreamed, and RISS. Two authors independently assessed the quality of selected studies and data was synthesized. Results: Non-face-to-face services promoted loneliness and social isolation, social support and quality of life, other emotional responses, attitudes and usability, and diet and exercise. As the composition and method of services are being tried in various ways, it is necessary to develop a comprehensive service using ICT to provide systematic intervention to the elderly in the local community. Conclusion: Reflecting the difficulties in implementing face-to-face services due to COVID-19, it is expected to be used as basic data for developing comprehensive non-face-to-face services that meet the major needs of the elderly people and maintain the continuity of care.

The traditonal inpatient acute hospital setting is organized primarily for the intensive management of disease, but not well-suited for continuity of care for the chronically ill patients after being discharged from hospital. For the planning of the continuity of care, firstly, it is necessary to assess the home care needs of the discharged pateints in the context of the nursing diagnosis. Therefore, this study is designed to identify the home nursing care need trajectory of the patients with chronic illness after discharged from one of the the General Hospitals in Seoul, Korea. The subjects are the patients with chronic illness such as stroke, musculoskeletal disease, hypertension, cancer etc., in average age of 52. 2 years old. The findings of this study are as follows : 1) The limitaion of ADL has been constantly facing to the subjects and has not been changed 4 weeks after being discharged. And the sense of with-drawal was getting worse at 4th weeks than the 1st week after being discharged. 2) The lists of the patient's problems are the impairment of mobility, elimination pattern, inactivity, impairment of skin integrity, ineffective airway clearance, and potential anxiety, self concept deficit, ineffective family coing, etc. Those problems were diminished in quantity at the first week after discharged, but at the 4th week, those problems were getting worse. 3) The need of specialized nursing care such as tube feeding, ostomy care, $O_2$ inhalation, IV therapy, teaching and exercise are considered as the most consisting problems facing to the subjects. 4) In general, the chronically ill patients and their caregivers have not been adapted well even at the 4th weeks after being discharged. 5) Considering those findings, the basic care for patients should be given and the trainging for process of the adaptation after discharged should be encouraged prior being discharged from hostital. For this suggestion, the systematic discharge planning should be carried and the hospital based home nursing model should be implemented at the general hospital for the chronically ill patients.

본 연구에서는 탐구 요소 중심의 단편적 활동 혹은 지시적인 확인 실험과 대비되는 종합적이고 포괄적인 탐구 활동으로서 실제성, 개방성, 연속성을 특징으로하는 '확장적 과학 탐구'를 개념화하고 경기도 수원에 있는 '화성'을 소재로 하여 중학교 1학년 학생들에게 적합한 확장적 과학 탐구 과제를 개발하였다. 확장적 과학 탐구의 수행 과정에서 학생들의 인지적 참여도는 어떻게 변화하는지, 확장적 과학 탐구 과제의 특징은 인지적 참여도에 어떠한 영향을 미치는지 조사하는 것이 이 연구의 목적이다. 연구 대상은 서울에 소재한 중학교의 1학년 4개 학급 학생 128명이었다. 교과서의 '힘과 운동' 단원에 제시되어 있는 2가지의 탐구 과제와 4가지의 확장적 탐구 과제를 수행하는 과정에서 각 탐구 활동이 끝난 직후 인지적 참여도에 대한 설문을 반복 시행하였고 확장적 탐구 활동이 모두 끝난 다음에는 6개의 과제에 대한 인지적 참여도를 비교해서 응답하도록 하였다. 이러한 정량적 자료와 함께 10명을 대상으로 면담을 실시하여 확장적 탐구 과제의 특정이 학생들의 인지적 참여도에 미치는 영향을 탐색하였다. 각 탐구 과제별 인지적 참여도를 분석한 결과 확장적 과학 탐구에서 교과서에 준한 탐구에 비해 탐구의 목적, 방법, 결과 등 탐구 내용과 과정 전반에 대해 이해한 정도는 증가하지 않았으나 더 능동적으로 열심히 참여했으며( p<0.01) 확장적 탐구의 후반부에서는 전반부에 비해 '이해'와 '몰두'가 모두 유의하게 증가하였다( p<0.05). 확장적 과학 탐구에서 교과서 탐구에 비해 '몰두'가 증가된 이유를 면담 결과에서 분석해 보면 확장적 과학 탐구 과제의 개방성이 주요 원인이었음을 알 수 있다. 또한 전반부에 비해 후반부에서 '이해'의 정도가 높아진 이유는 유기적으로 구성된 선행 탐구의 경험이 영향을 미친 것으로, '몰두'의 정도가 증가된 것은 탐구 과제 자체의 개방성이 증가했기 때문으로 해석할 수 있다.

사람의 인지기능 중 주의력은 감각기관을 통해 방대한 자극 중 필요한 자극에만 의식을 집중하는 과정이다. 주의력은 실내 온도 등 노출 환경에 영향을 받는 것으로 알려져 있다. 스포츠 분야에서는 냉각 팩 등을 사용한 직접 전도 방식의 냉각이 광범위하게 사용되어 효과를 보고 있으나 전도에 의한 냉각이 주의력과 같은 인지 활동에 미치는 영향에 대해서는 알려진 바가 없다. 본 연구에서는 경추부 후면 부위에 특수 제작된 냉각 패드를 적용할 때 주의력에 미치는 영향을 살펴보기 위해 수행되었다. 40명의 피검사자를 네 집단으로 나누고 독서 및 산책 중 냉각 패드의 적용에 따라 주의력이 차이를 보이는지 살펴보았다. 주의력은 FAIR 주의력 검사를 통해 평가되었으며, 선택적 주의력을 의미하는 능력지수, 주의력의 정확도를 나타내는 통제지수, 균일한 주의력의 유지 기간을 나타내는 지속성지수에 대한 분산분석과 사후분석을 실시하였다. 결과적으로, 독서 및 학습 등 시각적 주의력이 지속적으로 요구되는 경우 냉각 패드의 적용을 통한 전도 냉각이 선택적 주의력을 확대시키고 균일한 주의력을 유지하는데 도움이 된다. 또한, 선택적 주의력의 향상과 균일한 주의력의 유지를 위해 가벼운 신체 활동이 도움이 된다. 다만 이 경우 전체 독서 시간의 감소를 전제로 하여야 한다.

This paper investigates the damage identification of the concrete pile element through axial wave propagation technique using computational and experimental studies. Now-a-days, concrete pile foundations are often common in all engineering structures and their safety is significant for preventing the failure. Damage detection and estimation in a sub-structure is challenging as the visual picture of the sub-structure and its condition is not well known and the state of the structure or foundation can be inferred only through its static and dynamic response. The concept of wave propagation involves dynamic impedance and whenever a wave encounters a changing impedance (due to loss of stiffness), a reflecting wave is generated with the total strain energy forked as reflected as well as refracted portions. Among many frequency domain methods, the Spectral Finite Element method (SFEM) has been found suitable for analysis of wave propagation in real engineering structures as the formulation is based on dynamic equilibrium under harmonic steady state excitation. The feasibility of the axial wave propagation technique is studied through numerical simulations using Elementary rod theory and higher order Love rod theory under SFEM and ABAQUS dynamic explicit analysis with experimental validation exercise. Towards simulating the damage scenario in a pile element, dis-continuity (impedance mismatch) is induced by varying its cross-sectional area along its length. Both experimental and computational investigations are performed under pulse-echo and pitch-catch configuration methods. Analytical and experimental results are in good agreement.

A theoretical research project is undertaken to develop integrated analysis and design tools for long span composite beams in modern high-rise buildings, and it aims to develop non-linear finite element models for practical design of composite beams. As the first paper in the series, this paper presents the development study as well as the calibration exercise of the proposed finite element models for simply supported composite beams. Other practical issues such as continuous composite beams, the provision of web openings for passage of building services, the partial continuity offered by the connections to columns as well as the behaviour of both unprotected and protected composite beams under fires will be reported separately. In this paper, details of the finite elements and the material models for both steel and reinforced concrete are first described, and finite element studies of composite beams with full details of test data are then presented. It should be noted that in the proposed finite element models, both steel beams and concrete slabs are modelled with two dimensional plane stress elements whose widths are assigned to be equal to the widths of concrete flanges, and the flange widths and the web thicknesses of steel beams as appropriate. Moreover, each shear connector is modelled with one horizontal spring and one vertical spring to simulate its longitudinal shear and pull-out actions based on measured load-slippage curves of push-out tests of shear connectors. The numerical results are then carefully analyzed and compared with the corresponding test results in terms of load mid-span deflection curves as well as load end-slippage curves. Other deformation characteristics of the composite beams such as stress and strain distributions across the composite cross-sections as well as distributions of shear forces and slippages in shear connectors along the beam spans are also examined in details. It is shown that the numerical results of the composite beams compare well with the test data in terms of various load-deformation characteristics along the entire deformation ranges. Hence, the proposed analysis and design tools are considered to be simple and yet effective for composite beams with practical geometrical dimensions and arrangements. Structural engineers are strongly encouraged to employ the models in their practical work to exploit the full advantages offered by composite construction.

본 연구는 음악치료가 119구급대원(이하 구급대원)의 외상 후 스트레스(post-traumatic stress; PTS) 감소에 미치는 영향과 음악치료 효과의 지속성을 알아보고자 수행되었다. 연구대상은 C지역의 구급대원 42명으로 2019년 11월 25일부터 2020년 3월 1일까지 연구를 진행하였다. 실험군 21명은 매일 2회씩 5일간 총 10회의 음악치료 프로그램을 진행하였다. 프로그램은 음악치료 전문가 2인에 의해 진행되었으며, 각 단계는 즉흥적으로 연주하기, 리듬 창작 활동, 난타, 신체 활동 등 목표에 필요한 중재기법이 적용되었다. 대조군은 실험군의 프로그램 진행과 동일한 시간에 자유로운 휴식(TV시청, 휴대폰게임, 수면, 운동 등)을 취하도록 하였다. 연구 결과 대조군은 음악치료 적용 전과 후의 외상 후 스트레스의 차이가 없었으나, 실험군은 음악치료 적용 전에 비해 직후의 PTS가 크게 감소하였고, 4주 후와 12주 후에는 PTS가 점차적으로 증가하였다(p<.05). 따라서 정기적이고 반복적인 음악치료는 구급대원의 외상 후 스트레스 수준을 경감시킬 수 있는 효과적인 방법으로 판단된다.
