There was a certification of the substances, the objects, the main concepts, and the subjects of nursing as the result of movement to establish scientific system of the nursing after 1960s. According as the subjects of nursing was changed from disease itself and health problem of the past to human, we approached nursing problem by applying several nursing theories to offer special, individual, and scientific nursing to active nursing client. As that, more systemically nursing activity is tried, so the necessity of grasping the nursing client's nursing problem take place and the development of the assessment tool to appreciate the nursing problem is needed. Moreover, though nursing process is applied to make progress students clinical demonstration more completely, more detailed assess-ment tool is strongly required, so this study is attended. We thought that the assessment process certifying the nursing problem of nursing client of adult which is defined as the stage that mental and physical maturity of the human development stages is developed by many scholars should assess the degree of self care ability, so this study developed the assessment tool depended on Orem's Self Care theory by taking the merits of existing assessments tools through the investigation of many documents.

The termite damage on wooden architectural heritages has been increasing due to climate change and afforestation. In addition, introduction of invasive termite has been concerned because of rise of the minimum temperature and the increased trade volume of wooden materials. In this study, We review invasive termite species of which could possibly cause damage to the wooden architectural heritages and we discussed ways to reduce the damage by invasive termites.

Direct conversion of creep data to dynamic moduli using point-wise method

김시현,이정행,조광수 한국유변학회 2021 Korea-Australia rheology journal Vol.33 No.2

We developed a new numerical method which converts creep data to dynamic moduli without relying on viscoelastic spectra of relaxation or retardation times. This algorithm is an improvement of the previous ones (Kwon et al., 2016) in the reduction of artificial waviness in the terminal regime as well as the noise due to measurement errors. The method is the application of the point-wise polynomial regression which reduces the polynomial order dramatically compared with previous method in order to suppress the waviness.

Classification Model to Discriminate People with and without Pain in the Lower Back and Lower Limb using Symmetry Data

김시현,정시우,박규남 KEMA학회 2021 근골격계과학기술학회 Vol.5 No.2

Background Multiple factors are associated with lower back and lower limb (LB & LL) pain, such as impaired muscle strength, balance, endurance, and motor control, and altered movement patterns. Symmetry of motion, strength and balance are goals for rehabilitation in patients with LB & LL pain. When classifying patients before or during on- and offline assessment, it is necessary that an easy to use functional test be available for clinicians. Purpose To establish a classification tree model for discriminating people with and without LB & LL pain during walking using symmetry values from side plank endurance test, hip abductor strength test, one-leg standing time tests and walking tests. Study design Cross-sectional study Methods A total of 100 subjects with and without LB & LL pain during walking participated. We measured the side plank endurance time, hip abductor strength and one-leg standing time with eyes open and closed, and the sagittal and frontal head angles at comfortable and fast walking speeds using a wearable wireless earbud sensor and calculated the symmetry index (SI) for each test. Classification and regression tree analysis with 10-fold cross validation was used to develop the classification model. Results The classification tree had 83% accuracy for discriminating people with and without LB & LL pain during walking. The most important factor for classification was the SI of the one-leg standing time with eyes closed; the second-most important factor was the SI of the frontal head angle during fast walking. Conclusions The present classification model can differentiate people with and without LB & LL pain during walking based on symmetry data acquired during functional tests, such as one-leg standing time with the eyes closed and fast walking test using the wearable device. Based on the present results, clinicians can classify patients before and during on- and offline assessments using cutoff values of the SI of the one-leg standing test with eyes closed of 63.88%, and of frontal head motion during a fast-walking test of 63.31%.

김시현,박보빈,홍성은,유성률,이장호,김사현,이평재,조은경,문철,Kim, Si Hyun,Park, Bo Bin,Hong, Sung Eun,Ryu, Sung Ryul,Lee, Jang Ho,Kim, Sa Hyun,Lee, Pyeongjae,Cho, Eun-Kyung,Moon, Cheol 대한임상검사과학회 2019 대한임상검사과학회지(KJCLS) Vol.51 No.2

본 연구는 2-methoxy-1,4-naphthoquinone (MQ)이 Monocyte chemoattractant protein-1 (MCP-1)에 의해 유도된 단구 유주에 미치는 효과를 알아보고자 진행되었다. 단구의 유주(migration) 현상은 신체 방어와 면역반응에 중요한 현상이다. MQ는 아시아권 국가에서 다양한 질병과 통증 치료에 민간요법으로 오랫동안 사용되었던 봉선화(Impatiens balsamina) 잎으로부터 추출한 주요 성분이다. 단구 세포주 THP-1를 이용하여 실험을 진행하였으며, MQ의 세포독성, MCP-1에 의해 유도된 유주 현상에 미치는 영향을 transwell system을 이용하여 확인하였다. MQ 작용기전을 이해하기 위해 cAMP 발현 및 Erk1/2 인산화를 각각 ELISA, Western-blot 기법을 통해 분석하였다. MQ의 단구 세포주 THP-1에 대한 MQ의 세포독성은 $10{\mu}M$ 농도에서 나타나기 시작했으며, $100{\mu}M$ 농도에서 약 50% 가량의 세포독성을 확인했다. 염증성 화학주성 인자 MCP-1에 의해 유도된 단핵구 세포주 THP-1의 유주현상은 MQ 처리 후 농도증가에 비례하여 증가하였으며, $0.1{\mu}M$ 농도의 MQ를 처리했을 때 가장 높은 증가를 보였다. MCP-1 단독 처리 시 감소하는 cAMP 의 배양액 내 발현은 MQ 동시 처리 시 더욱 감소하였고, 유주현상과 마찬가지로 $0.1{\mu}M$ 농도에서 가장 감소하였다. MCP-1의 수용체인 C-C motif chemokine receptor 2 (CCR2) 신호전달 과정에 관여하는 주요 신호전달 단백질인 Erk1/2의 인산화도 $0.1{\mu}M$ MQ 동시 처리 시 증가하였다. 이상의 결과를 통해 MQ가 MCP-1에 의해 유도되는 THP-1 세포주의 유주현상을 증가시키며, 연관된 cAMP 발현을 감소, Erk1/2 인산화는 증가시키는 경향을 확인하였다. This study examined the effects of 2-methoxy-1,4-naphthoquinone (MQ) on the monocyte chemoattractant protein-1 (MCP-1)-induced migration of monocytes, which is an important phenomenon for the body defense and immune response. MQ is a major component extracted from Impatiens balsamina leaves, which have been used for many years in Asian medicine for the treatment of a range of diseases and pain. The cytotoxicity of MQ began to appear at a concentration of $10{\mu}M$, and approximately 50% cytotoxicity was confirmed at $100{\mu}M$. The MCP-1 induced migration of the THP-1 monocyte cell line increased after MQ treatment in a dose dependent manner and the largest increase was observed at $0.1{\mu}M$. The level of cAMP expression decreased after a treatment with $0.1{\mu}M$ MQ. The phosphorylation of extracellular signal-regulated kinases 1/2 (Erk1/2), a key signaling protein involved in the signaling pathway of C-C motif chemokine receptor 2 (CCR2), a receptor for MCP-1, was increased by the simultaneous treatment of $0.1{\mu}M$ MQ. These results show that MQ increases the MCP-1-induced migration of THP-1, decreases the level of cAMP expression, and increases the level of Erk1/2 phosphorylation.

This study was intended to investigate competencies of voucher service of speech and language pathologists, and to suggest methods for improving service competency by reconsidering the importance of speech and language pathologists in social services. This study conducted questionnaire survey on 119 speech and language pathologists across the country, and analyzed 74 items of 7 items on general characteristics of speech and language pathologists, 20 items on voucher service knowledge, 31 items on skills, and 16 items on attitude. First, it was identified that knowledge in voucher service of speech and language pathologists was relatively low compare to the knowledge demand as they were reported to be on average 2.62(±0.68) points and 3.58 points(±0.89) out of 5. Secondly, the level of skills as service personnel was 3.50 points(±0.94) on average, and in the order of development rehabilitation service, support service of speech development, and language development support services. Thirdly, satisfaction and role related stress for voucher service were 3.83 points(±0.66) and 3.25 points(±0.81) each, and showed very positive attitude for the necessity of voucher but had high stress for document record. Fourthly, knowledge in voucher service, skills, and attitude had strong positive correlation. By reviewing these results comprehensively, this study suggested multidimensional cooperation methods asthe nations’ institutional improvement, educational effort of association and school, and individual training for improvement in competencies of voucher service of speech rehabilitation specialists.
