PURPOSE: This study is to grasp factors influencing the quality of life in older adults after total knee replacement. METHODS: This study was conducted with 165 older adults who had TKR at four orthopedic hospitals in D city. Data were analyzed using one-way ANOVA, independent t-test, Pearson's correlation, and stepwise multiple linear regression with SPSS 19.0 software. RESULTS: Pain and depression were negatively correlated with range of motion, social support, while sense of coherence was positively correlated with quality of life. Sense of coherence (43%, β=.40), pain (8%, β=−.30), and depression (3%, β=−.20) on the Physical Component Summary in the quality of life have significant explanatory power of 54%. Sense of coherence (49%, β=.44), social support (6%, β=.25), and depression (3%, β=−.22) on the Mental Component Summary in the quality of life have significant explanatory power of 58%. CONCLUSION: This study suggests developing a program to improve the quality of life in older adults who had TKR, considering factors such as sense of coherence.

PURPOSE: This study identified the relationships among subjective health status, wisdom, and self-care agency of Korean older adults. METHODS: The participants were 274 older adults from Daegu, aged over 65 years. Data were collected by visiting two social welfare centers, two senior welfare centers, and nine senior centers in Daegu from January 18 to February 5, 2013. Data were analyzed through one-way ANOVA, independent t-test, Pearson's correlation, and stepwise multiple linear regression using the IBM SPSS/WIN 19.0 statistical program. RESULTS: A significant positive correlation was found among older adults' subjective health status, wisdom, and self-care agency. Self-care agency was affected by wisdom (47%, beta=.55), the physical component summary (18%, beta=.31) and mental component summary (1%, beta=.12) of subjective health status, and the absence of disease (2%, beta=.13). CONCLUSION: This study suggests that nursing interventions to promote self-care agency in older adults should be developed based on the characteristics of their subjective health status and wisdom.

PURPOSE: This study was done to identify the relationships among diabetic health leader attitude, diabetic knowledge, and health conservation in highly educated elders. METHODS: The participants were 119 elders aged 65 or more who were attending the senior welfare centers in D and K City and had at least a high school degree. Data were collected from June 10 to July 7 in 2013. Data analysis included one-way ANOVA, independent t-test, Pearson's correlation, and stepwise multiple regression, done with the SPSS/WIN 19.0 program. RESULTS: A positive correlation was found among diabetic health leader attitude, diabetic knowledge, and health conservation. Health conservation explained 26% (beta=.31) and diabetic knowledge explained 2% (beta=.18) of the variance in diabetic health leader attitude. CONCLUSION: The results indicate that to increase diabetic health leader attitude among highly educated elders, health leader programs are needed for increasing their diabetic knowledge and health conservation.

PURPOSE: The authors of the present study compared the effects of tenectomy and posterior tenectomy of the superior oblique for treating superior oblique overaction (SOOA). METHODS: The records of 30 eyes of 19 patients who underwent tenectomy or posterior tenectomy of the superior oblique alone or in combination with surgery on other horizontal rectus muscles from April 2005 through November 2010 were reviewed. The review was performed in 3 patients who underwent unilateral superior oblique tenectomy, 5 patients who underwent unilateral superior oblique posterior tenectomy, 3 patients who underwent bilateral superior oblique tenectomy, 6 patients who underwent bilateral superior oblique posterior tenectomy, and 2 patients who underwent superior oblique posterior tenectomy and tenectomy. RESULTS: The mean age of the patients was 14.2 years, and the mean follow-up period was 20 months. Through superior oblique tenectomy (11 eyes) and superior oblique posterior tenectomy (19 eyes), the amount of SOOA decreased from +2.27 to +0.09 and from +1.84 to +0.93, respectively. Except for 1 out of 11 eyes with superior oblique tenectomy, SOOA was completely corrected, although SOOA remained in 6 eyes after posterior tenectomy. Therefore, the correctional effects of the 2 methods differed; both procedures showed insignificant correctional effects on vertical strabismus. CONCLUSIONS: Superior oblique tenectomy has a superior long-term weakening effect; however, posterior tenectomy showed a comparable effect in the patient with moderate to severe SOOA. Both of these methods had few complications and are considered to be effective superior oblique weakening procedures.

Purpose: Idiopathic scoliosis is the most common form of scoliosis, and the risk of onset and progression has been found to correlate with growth spurts. Therefore, treatment with recombinant human growth hormone (GH) treatment in short children may initiate and/or aggravate scoliosis. The aim of this study was to investigate the relationship between idiopathic scoliosis and GH treatment in short children. Methods: The medical records of 113 subjects seen at the participating institution between January 2010 and December 2020 and who were diagnosed with GH deficiency and small for gestational age, had idiopathic short stature, and were treated with GH for at least one year were reviewed. Scoliosis was defined as a Cobb angle greater than 10 degrees as assessed using a spine x-ray. Clinical data and laboratory findings before and 12 months after GH treatment were compared. Results: There was significant increase in height, height-standard deviation score, insulin-like growth factor 1, and insulin-like growth factor binding protein 3 (p<0.001) with GH treatment. However, there were no significant differences in the average Cobb angle (6.2°±3.3° vs. 6.1°±3.5°, p=0.842) and the prevalence of scoliosis (9.7% vs. 13.3%, p=0.481) before and after one year of GH treatment. A comparative analysis of both initial Cobb angle and change in Cobb angle during GH treatment showed no relationship with other factors. Conclusion Although GH treatment in short children increased height and growth velocity, it was not associated with development or aggravation of idiopathic scoliosis.

Purpose: Since the coronavirus disease 2019 (COVID-19) pandemic, the educational environment has moved toward online-based education, which may significantly impact medical students’ educational experiences. However, the same events may be understood differently by different individuals depending on their personalities. Therefore, the changing educational environment during the COVID-19 pandemic may not have been perceived equally by all students. This study aimed to investigate medical students’ personality profiles and the difference between academic burnout and engagement according to their personality profiles. Methods: During the 2021–2022 academic year, when online-based education was implemented due to the pandemic, a survey was conducted among medical students in Korea (N=325). First, we used latent profile analysis to identify the sub-types of the Big Five personalities. Second, we used analysis of variance and post hoc comparisons to study the difference between academic burnout and engagement among these sub-types. Results: The Big Five personality traits of medical students in our sample were classified into three profiles. Profiles with relatively high neuroticism, while other personality traits were low, had both the highest academic burnout and academic engagement. Alternatively, the profiles showing relatively low neuroticism, while other personality traits were high, had the lowest academic burnout and the highest academic engagement. Conclusion Personality is a stable trait that affects an individual’s behavior and response to the environment. Thus, individuals with specific personalities differ in their reactions to their environment. This may provide an advantage to some medical students’ careers.

PURPOSE: In order to obtain better quantitation of kidney uptake, this study is to evaluate a conjugate view method (CVM) using a geometric mean attenuation correction for kidney uptake and to compare it to Gate's method. MATERIALS AND METHODS: We used a Monte Carlo code, SIMIND and a Zubal phantom, to simulate kidney uptake. SIMIND was both simulated with or without scatter for the Zubal phantom. Also, a real phantom test was carried out using a dual-head gamma camera. The activity of 0.5 mCi was infused into two small cylinder phantoms of 5 cm diameter, and then, they were inserted into a cylinder phantom of 20 cm diameter. The results by the CVM method were compared with ideal data without both of attenuation and scatter and with Gate's method. The CVM was performed with or without scatter correction. The Gate's method was performed without scatter correction and it was evaluated with regards to 0.12 cm (-1) and 0.15 cm (-1) attenuation coefficients. Data were analyzed with comparisons of mean counts in the regions of interest (ROI), profiles drawn over kidney images and linear regression. Correlation coefficients were calculated with ideal data, as well. RESULTS: In the case of the computer simulation, mean counts measured from ideal data, the CVM and the Gate's method were (right: 998 +/- 209, left: 896 +/- 249), (right: 911 +/- 207, left: 815 +/- 265), and (right: 1065 +/- 267, left: 1546 +/- 267), respectively. The ideal data showed good correlation with the CVM and the correlation coefficients of the CVM, Gate's method were (right: 0.91, left: 0.93) and (right: 0.85, left: 0.90), respectively. CONCLUSION: The conjugate view method using geometric mean attenuation correction resulted in better accuracy than the Gate's method. In conclusion, the conjugate view method independent of renal depths may provide more accurate kidney uptake.
