  • This study was conducted to develop a supportive nursing intervention plan for the young-old by identifying the essence and meaning structure of re-employment experience after retirement. Participants of this study were selected by convenience sampling of seven Korean young-old individuals from 60 to 74 years of age who had re-employment experience after retirement in C city. Data were collected from June to August of 2016 based on an in-depth interview and tape-recording. The interview data were analyzed by the phenomenological analysis method developed by Giorgi. The analysis revealed the following constituents; confusion in response to the change of life, recognizing that it is not easy to work again, adaption to new changes, opening a new life. It is becoming increasingly important that nurses, who have played an important role in elderly nursing because of the increase in average life expectancy and overall elderly population, take care of extended tasks throughout the society, away from clinical work. Therefore, a social support system and nursing guidelines necessary for continuous nursing intervention should be provided so that the elderly, including those at early retirement age, can be satisfied with their life after retirement.

  • This was a qualitative study to explore and better understand the adaptation experience and processes of peoples with fibromyalgia syndrome (FMS), as well as to develop a substantive theory using the grounded theory method. There were 13 patients (12 females and 1 male) who received FMS treatment from Rheumatic Medicine outpatient department of one general hospital. The data were collected through an in-depth interview between January and May of 2014. Transcribed interview contents were analyzed by the grounded theory method of Corbin and Strauss (2008). As a result, a total of 98 concepts, 26 sub-categories, and 10 categories were identified through the open coding process. The process of adaptation experience showed 4 steps: perception of uncertainty and limited condition, evaluation of self-control possibility and determinations of expectations of life, searching and trying of strategies, as well as self-regulation. The 4 types of adaptation experience were expansionary, complacently, effusively and withering. The 'protective self-regulation' theory was derived from the core category of 'learning to self-regulation method'. Patients with FMS has repeatedly attempted these strategies of protective self-regulation in order to gain stability from uncertainty and limited condition of the disease. Based on these results, it is necessary to develop an educational program for patients and families which has appropriate nursing intervention strategies in accordance with the types of adaptation.

  • ECG signal has the feature that is repeated in a cycle of P, Q, R, S, and T waves and is sampled at a high sampling frequency in general. By using the feature of periodic ECG signals, maximizing compression efficiency while minimizing the loss of important information for diagnosis is required. However, the periodic characteristics of such amplitude and period is not constant by measuring time and patients. Even though measured at the same time, the patient's characteristics display different periodic intervals. In this paper, an adaptive multi-level coding is provided by coding adaptively the dominant and non-dominant signal interval of the ECG signal. The proposed method can maximize the compression efficiency by using a multi-level code that applies different compression ratios considering information loss associated with the dominant signal intervals and non-dominant signal intervals. For the case of long time measurement, this method has a merit of maximizing compression ratio compared with existing compression methods that do not use the periodicity of the ECG signal and for the lossless compression coding of non-dominant signal intervals, the method has an advantage that can be stored without loss of information. The effectiveness of the ECG signal compression is proved throughout the experiment on ECG signal of MIT-BIH arrhythmia database.

  • This study was performed to investigate non-invasive behavioral pain assessment of dogs after surgery, and the analgesic effects of butorphanol after intestinal anastomosis in dogs. In this study, five dogs in the Control Group were anesthetized, but did not undergo surgery. Five dogs in the Analgesic Group were undergone intestinal anastomosis and treated with butorphanol. Five dogs in the Non-analgesic Group were also undergone intestinal anastomosis without analgesic treatment. The dogs in the Analgesic Group received butorphanol (0.4 mg/kg, IM) before and immediately after operation, while dogs in Control and Non-analgesic Groups received isovolumetric doses of sterile saline. The behavior of dogs were videotaped for 400 mins after anesthesia, during which time a researcher interacted with the dog once per each 80 mins. At each interaction, the researcher recorded behavioral pain score, using University of Melbourne Pain Scale. Interactive and non-interactive behaviors were observed and quantitated by a single observer using focal continuous sampling method. Vocalizations were obtained during 400 mins after anesthesia, and duration of call, intensity, pitch, 1-4 Formant were analyzed. Surgery affected an increasing of pain score. During interactions with researcher, greeting behaviors were decreased after surgery. Differences between Analgesic group given analgesic or that given a placebo drug were readily understood using quantitative behavioral measurements and vocalization. Significant difference between Analgesic group given butorphanol or that the given placebo drug was apparent(p< 0.05).

  • Low-density lipoprotein cholesterol (LDL-C) is a major modifiable risk factor for cardio- cerebrovascular disease. In clinical practice, however, it is primarily calculated using the Friedewald formula as a cost-effective method. The aim of this study was to compare Friedewald-estimated and directly measured LDL-C values and assess the concordance in guideline LDL-C risk classification between the two methods. The data were derived from the 2009 and 2010 Korea National Health and Nutrition Survey (KNHANES). Analysis was done for 4,319 subjects with lipid panels-total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), directly measured LDL-C using an enzymatic homogeneous assay, and triglycerides (TG). For subjects with TG lower than 400 mg/dL, Friedewald-estimated and directly measured LDL-C were highly correlated (r = 0.958, p < 0.001) and overall concordance was 82.7%. As TG increased, overall concordance decreased. Overall concordance was 85.4% at TG lower than 150 mg/dL; 78.2% at TG of 150-199 mg/dL; and 71.4% at TG of 200-399 mg/dL. The Friedewld equation tended to overestimate LDL-C when TG are of < 150 mg/dL; however, underestimate LDL-C when TG are of ${\geq}150mg/dL$. As a result, Friedewald estimation misclassified 382 subjects (9.1%) in a higher category versus 348 subjects (8.3%) in a lower category. Our findings suggest that overestimation of LDL-C by the Friedewald formula can be a great problem as well as underestimation.
