Purpose : The purpose of the study was to examine if a respiratory muscle strengthening training in patients with stroke can improve their pulmonary function. Methods : Volunteers were included for the study if a patient diagnosed stroke more than 6 months and had 24 points or higher in MMSE-K scores. Twenty-eight subjects participated in this study and were randomly divided into two groups; a breathing exercise group(n=14) and a control group(n=14). The intervention for all subjects was conducted for 20minutes, three times a week for 4 weeks. Subjects for the breathing exercise group had the respiratory muscle strengthening training using spiro-tigers, where-as subjects in the control group got their usual treatment ie a postural training. The six-minute walking test(6MWT) and the pulmonary function tests(FVC, $FEV_1$, $FEV_1$/FVC, VC, Vt, IRV and ERV) were employed to assess treatment effects at baseline and after their intervention. Results : Twenty-four subjects finished their 4-week treatment programs. The general characteristics between groups were found to be similar (p>0.05). The pulmonary function between groups were also observed no difference across groups at the baseline measurement (p>0.05). In the post treatment group comparison, subjects in the breathing exercise group showed an increase in lung function with VC ($2.73{\pm}0.80{\ell}$) and Vt ($0.87{\pm}0.38{\ell}$) than those in the control group ($1.91{\pm}0.80{\ell}$ and $0.48{\pm}0.22{\ell}$ respectively) (p<0.05). However, there was no difference found in 6MWT, FVC, $FEV_1$, $FEV_1$/FVC, IRV, and ERV across groups (p>0.05). Conclusion : A significant increase in VC and Vt was found in subjects with stroke, who had four-week training on respiratory muscle strengthening. However, respiratory muscle strengthening showed no effect on walking speed and FVC, $FEV_1$, $FEV_1$/FVC, IRV, and ERV in patients with stroke.

Purpose: This study was conducted to develop and to determine the effects of an integrated symptom management program for prevention of recurrent cardiac events after percutaneous coronary intervention. Methods: Subjects consisted of 58 CAD patients (experimental group: 30, control group: 28). The experimental group participated in an integrated symptom management program for 6 months which was composed of tailored education, stress management, exercise, diet, deep breathing, music therapy, periodical telephone monitoring and a daily log. The control group received the usual care. Results: The experimental group significantly decreased symptom experiences and the level of LDL compared to the control group. The experimental group significantly increased self care activity and quality of life compared to the control group. Although no significant difference was found in cardiac recurrence, the experimental group had fewer recurrences. Conclusion: These results suggest that an integrated symptom management program for prevention of recurrent cardiac events after percutaneous coronary intervention can improve symptom aggravation, recurrent rate, self care activity and quality of life. Nursing interventions are needed to maintain and further enhance the quality of life of these patients and the interventions should be implemented in the overall transition period.

A 37 year old male patient was suffered from severe labored breathing caused by post tracheostomy stenosis, which was localized at the mediastinal trachea [cuffed tracheal stenosis] and ranged 1.5 cm in length and approximately 3 ram. in diameter on tracheogram. After dilation of tracheal stenosis with dilator, endotracheal intubation was tried for induction of anesthesia and control of respiration during operation. A tube was placed just beyond the tracheal stenosis without respiratory difficulty. Under the endotracheal anesthesia, circumferential resection of the mediastinal trachea containing the stenosis, approximately 2 cm in length [4 tracheal rings}, was carried out and primary direct end to end anastomosis was performed with interrupted submucosal sutures [3-0 Dexon] and mobilization of trachea Postoperative tracheostomy was not performed. The patient was completely relieved from dyspnea immediately after operation. Post-operative convalescence was entirely uneventful and at present, about 3 months after operation, he is now conducting a usual life. From the literature and our experience, the etiology and treatment of post-tracheostomy stenosis were discussed.

The aim of this paper is to describe an advanced method of the fault diagnosis using Control Theory with reference to a crack detection, a new way to localize the crack position under influence of the plant disturbance and white measurement noise on a rotating shaft. As the first step, the shaft is physically modelled with a finite element method as usual and the dynamic mathematical model is derived from it using the Hamilton-principle and in this way the system is modelled by various subsystems. The equations of motions with a crack are established by the adaption of the local stiffness change through breathing and gaping[1] from the crack to the equation of motion with an undamaged shaft. This is supposed to be regarded as a reference system for the given system. Based on the fictitious model of the time behaviour induced from vibration phenomena measured at the bearings, a nonlinear state observer is designed in order to detect the crack on the shaft. This is the elementary NL-observer(EOB). Using the elementary observer, an Estimator(Observer Bank) is established and arranged at the certain position on the shaft. In case, a crack is found and its position is known, the procedure, fro the estimation of the depth is going to begin.

Purpose: The purpose of this study was to investigate the effects of a structured preoperative instruction upon anxiety and postoperative self-care compliance. Methods: A randomized control group pre-post design was used. Sixty subjects undergoing cataract surgery were randomly assigned to one of two groups. The instruction consisted of cataract surgery procedure, sensory information, deep breathing, use of eye drop, and post op self-care regimen and was provided to the experimental group with control group receiving an usual treatment. State anxiety NRS, pulse, BP, and self-care compliance scale developed by Cho & Rho were used. Data were collected at two time periods: on the day of surgery in the clinic and prior to anesthesia in the operating room. The postoperative self-care compliance scores were measured at their second visits to the hospital after surgery. Data were analyzed using Kolmogorov Smirnov test, t-test, and Mann-Whitney U test. Results: There were significant differences between the two groups in the postoperative state anxiety (t=-3.57, p=.001) and the postoperative self-care compliance score (t=3.92, p<.001). There were no significant difference between the two groups in the postoperative blood pressure and pulse rate. Conclusion: The results of this study suggest that the structured preoperative instruction could be a nursing intervention for cataract surgery patients.

The goal of this paper is to describe an advanced method of the fault diagnois using Control Theory with reference to a crack detection, a new way to localize the crack position under infulence of the plant disturbance and white measurement noise on a rotating shaft. As a first step, the shaft is physically modelled with a finite element method as usual and the dynamic mathematical model is derived from it using the Hamilton - principle and in this way the system is modelled by various subsystems. The equations of motion with crack is established by adaption of the local stiffness change through breathing and gaping from the crack to the equation of motion with un-damaged shaft. This is supposed to be regarded as reference for the given system. Based on the fictitious model of the time behaviour induced from vibration phenomena measured at the bearings, a nonlinear State Observer is designed in order to detect the crack on the shaft. This is elementary NL- observer(EOB). Using the elementary observer, an Estimator(Observer) Bank is established and arranged at the certain position on the shaft. In case a crack is found and its position is known, the procedure for the estimation of the depth is going to begin.

전통시대의 문학을 생태주의적 관점에서 논의한다면 당대 지식인인 양반들과 사대부의 시조인 평시조에 나타난 자연관 정도로 생각하였던 탓에 사설시조나 서민작가는 큰 관심의 대상이 아니었다. 또한 사설시조 속의 '산것들'도 주목받지 못했다. 그것들은 시어로서는 부적절한, 이른바, '생경한 시어' 또는 '비시적 사물의 시화'라는 홀대를 받았다. 그 어떤 평자들도 그 살아 숨쉬는 것들을 '산것들'로 인식하지 않았고, 따라서 작품속의 주체적 대상으로도 인식하고자 하지 않았다. 그러나 사설시조에서는 경험적, 구체적, 일상적 동물들의 등장이 관심을 끈다. 이는 사실 양반들의 관념적 생물관과 비교될 만한 단서도 된다. 본고는 사설시조 속의 이들 '산것들'과 그들에 대한 작가의 시각과 인식에 대해 소박한 논의를 하였다. 본고에서 '산것들'은 살아 움직이는 것들을 의미한다. 먼저 사설시조 속의 '산것들'은 일상과 경험의 생물들이었다. 그것들은 더 이상 사설시조의 작가에게는 지식이나 관념적 생물이 아니었다. 생물환경적으로 도저히 공생할 수 없는 '산것들'이 함께 등장하는 것이 가능하거나 그 반대로 오랫동안 친숙한 일상경험에 근거하여 '산것들'에 대한 경험적 인식이 탁월한 작품도 있었다. 또한 '산것들'에 대한 사설시조 작가들의 친근하고도 애틋한, 그리고 우리 인간과 다를 바 없는 생명체에 대한 온기 있는 시선은 때로는 동일시의 대상으로 또 때로는 감정이입의 대상으로 파악하기도 하였다. 더러는 애증이 혼재하는 복합적 시선도 눈에 띈다. 사설시조 작가들의 삶은 온갖 '산것들'과 함께 하는 공생의 삶에 다름 아니다.
