흉부둔상에 의한 심장파열은 50% 이상의 치사율을 갖는 질환으로 응급실에 도착하기 전에 사망하는 경우가 대부분이다. 일반적으로 전형적인 심장압전을 동반하기 때문에 이학적 소견이나 심장초음파 또는 흉부전산화 단층촬영으로 진단이 가능하다. 그러나 저자의 경우와 같이 심장압전의 징후가 없이 중증 우측혈흉만 있는 경우 심장파열을 진단하는 것은 어렵다. 만약 고속의 자동차사고로 인한 흉부둔상을 받은 환자에서 늑골골절이 없이 우측에 중증의 혈흉이 있어 응급개흉술을 받아야 한다면 심장파열의 가능성을 염두에두고 수술을 계획하는 것이 필요하다고 생각한다. 본 인하대학교 흉부외과학 교실에서는 흉부둔상에 의한 중증우측 혈흉과 심낭파열을 동반한 심장파열 2례를 심패바이패스와 자가수혈 장치를 이용하여 효과적으로 치료하였기에 보고하는 바이다.

Our study was carried out to develop the severity-adjustment model for length of stay in hospital for percutaneous coronary interventions so that we would analysis the factors on the variation in length of stay(LOS). The subjects were 1,011 percutaneous coronary interventions inpatients of the Korean National Hospital Discharge In-depth Injury Survey 2004-2006 data. The data were analyzed using t-test and ANOVA and the severity-adjustment model was developed using data mining technique. After yielding the standardized value of the difference between crude and expected length of stay, we analysed the variation of length of stay for percutaneous coronary interventions. There was variation of LOS in regional differences, size of sickbed and insurance type. The variation of length of stay controlling the case mix or severity of illness can be explained the factors of provider. This supply factors in LOS variations should be more studied for individual practice style or patient management practices and healthcare resources or environment. We expect that the severity-adjustment model using administrative databases should be more adapted in other diseases in practical.

The purpose of this study was to explore process of life experience for mothers of children with severe disabilities. Strauss and Corbin's Grounded theory approach was used. Total 17 mothers who have experience of caring for severely disabled child participated. In-depth interviews was done from January 2010 to May 2011. Three to seven interviews were done for each participant. As a result of this study, 119 concepts, 41 subordinate categories and 20 categories have been revealed. The experience of caring children with severe disabilities were 'desolate life' 'plunging in darkness' 'managing to pull oneself' 'rising again' and 'rediscovering of life'. The core category of selective coding was rediscovering of new life from life in darkness. It is suggested that welfare policies need to be modified and new policies need to established for mothers who care for severely disabled children.

This study was conducted to identify the factors influencing the severity of pressure injuries of patients with pressure injuries admitted to acute university hospital. This study was a secondary analysis on the data of the study conducted to identify the factors influencing the deterioration of pressure injuries during hospitalization. The data were collected by retrospectively examining the medical records of patients with pressure injuries who were 18 years of age or older and who were admitted to acute university hospital from May 2017 to November 2018. We used data from 472 patients with pressure injuries at admission for this secondary analysis. In order to identify the factor influencing of severe pressure injuries compare to superficial pressure injuries, we analyzed the data using logistic regression analysis. As a result of the study, gender, body temperature, and patient's movement were identified as factors affecting severe pressure injuries. Therefore, special care is necessary to increased the number of position change for inpatients with pressure injuries, especially for patients with decreased mobility.

The purpose of this study was to examine the relationship of the severity, depression and to identify factors influencing quality of sleep in Restless Legs Syndrome(RLS) patients. A total of 303 consecutive RLS patients were assessed by self questionnaires and participant's medical records were reviewed for obtaining their clinical information. The collected data were analyzed by descriptive statistics, t-test, ANOVA, Pearson's correlation, and multiple regression. The quality of sleep was positively correlated with symptoms(r=. 21, p<.001) and depression(r=. 37, p<.001). The results of multiple regression analysis showed that significant variables influencing the quality of sleep were depression(${\beta}=.35$, p<.001), age(${\beta}=.21$, p<.001), and severity(${\beta}=.15$, p=.005). The explanation power of this regression model was 21.0% and it was statistically significant. As a result, to improve their sleep quality, the nursing interventions are required for RLS patients who have the depression, age, and severity.

Purpose : Atopic findings may be associated with severity of pneumonia in 2009 pandemic influenza A (H1N1) infection, which could suggest a possible association between atopic findings and the severity of viral infections. Thus, we studied association between atopic findings and severity of disease in children with H1N1 influenza infection. Methods : A retrospective study was performed in 74 children admitted in a single tertiary institute and confirmed as H1N1 patients by reverse transcriptase (RT) - polymerase chain reaction (PCR). They were divided into 2 groups according to the severity of pneumonia. We evaluated whether the atopic finding is risk factor between the two groups. Results : Children with severe pneumonia had higher percentages of serum eosinophilia (88% vs 40%, P <0.001), asthma (65% vs 35%, P =0.011), allergic rhinitis (71% vs 40%, P =0.009), and IgE level (P =0.007). We found positive correlations between aeroallergen sensitizations and severity of pneumonia (82% vs 53%, P =0.007). Conclusion : Among patients with H1N1 pneumonia, asthma and atopic findings are risk factors for severity of pneumonia.

Objectives : The purpose of this study was to quantitatively assess the degree of myasthenia gravis (MG) affecting mental health through the results of multiphasic military personality inventory in late adolescence. Methods : We collected and analyzed the results of the military personality inventory for healthy controls and MG patients among the 19-year-old men who visited the Military Manpower Administration from February 2007 to January 2010. Military personality inventory invented for Korean military test has similar system to Minnesota multiphasic personality inventory. Results : Among validity scales, each score of faking good, faking bad and infrequency subscales showed no difference between healthy control and MG groups, respectively (t=-0.51, p=0.607 ; t=0.11, p=0.913 ; t=1.41, p=0.158). Among neurosis scales, the score of somatization subscale was higher (t=2.29, p=0.023) in MG group. Among psychopath scales, the score of schizophrenia subscale was lower in MG group (t=-2.38, p=0.018). Conclusions : According to MPI results, we can confirm that MG patients in late adolescence may be more concerned with their somatic symptoms than the control group, and that they may be more likely to abide by the regulation and be conventional in their behavior than the control group.

This study focuses on the issue of automatic severity classification of dysarthric speakers based on speech intelligibility. Speech intelligibility is a complex measure that is affected by the features of multiple speech dimensions. However, most previous studies are restricted to using features from a single speech dimension. To effectively capture the characteristics of the speech disorder, we extracted features of multiple speech dimensions: voice quality, prosody, and pronunciation. Voice quality consists of jitter, shimmer, Harmonic to Noise Ratio (HNR), number of voice breaks, and degree of voice breaks. Prosody includes speech rate (total duration, speech duration, speaking rate, articulation rate), pitch (F0 mean/std/min/max/med/25quartile/75 quartile), and rhythm (%V, deltas, Varcos, rPVIs, nPVIs). Pronunciation contains Percentage of Correct Phonemes (Percentage of Correct Consonants/Vowels/Total phonemes) and degree of vowel distortion (Vowel Space Area, Formant Centralized Ratio, Vowel Articulatory Index, F2-Ratio). Experiments were conducted using various feature combinations. The experimental results indicate that using features from all three speech dimensions gives the best result, with a 80.15 F1-score, compared to using features from just one or two speech dimensions. The result implies voice quality, prosody, and pronunciation features should all be considered in automatic severity classification of dysarthria.
