Objectives: The aim of this study is to report the effects of Korean medical treatment with ByeolGab pharmacopuncture on a patient with a tension-type headache. Methods: We treated a tension-type headache using Korean medical treatment including ByeolGab pharmacopuncture for 6 days a week for 2 weeks. As a measurement, the numerical rating scale (NRS), the Henry Ford Headache Disability Inventory (HDI), and a six point Likert scale were used to confirm pharmacopuncture therapy efficacy. Results: After treatment, symptoms related to tension-type headache and other complaints were decreased and evaluation using the NRS, HDI, and six-point scale showed improvement in the patient. Conclusions: This study shows that Korean medical treatment with ByeolGab pharmacopuncture has beneficial effects on control of tension-type headache and improvement in quality of life for patients.

This study purports to investigate the determinants of individual personnel rating of the employees at a university hospital in Seoul, Korea. The sample used in this study consisted of 63 nurses, 41 para-medical staff (Clinical Pathologist, and Radiologist), and 67 administrative staff. Independent variables of the study included the achievement level of the selection test (English, major subject, and interview), post-entrance development factors (education and training, career development, supervisory support, co-worker support, and organizational support), and demographic characteristics. Data for the achievement level of the entrance exam and years for the first promotion were collected from the administrative records of the study hospital, while data for the post-entrance development factors were collected from the survey with self-administered questionnaires using 5-point Likert Scale during June 10-25, 2003. Collected data were analyzed using hierarchical multiple regression. The results of the study showed that achievement level of the interview and English exam at the selection test, education and training, organizational support, and supervisory support while working at the hospital, and length of duration (below 8 years) and educational background (4-year college graduates) among demographic variables had significant positive effects on the personnel rating. The results of the study imply that hospital administrators should make an effort to improve the validity of the selection test, and to motivate the employees to receive more education and training.

To quantify an concept we often use Likert summated rating scale of original or standardized variables in case the variables are relatively less. When variables have different scales, standardized values tends to be used rather than the original values. This is also true in evaluating systems. For example, we may use standardized values of local tax levy, population, and etc. and use the summed value of the standardized values to access the degrees of development. In this paper, we propose using a data-driven weighted sum for a scoring system and the way how to obtain the weights. We apply the proposed method to a real data set and find that proposed method is better than the usual summated rating scale.

Purpose: This study was designed to develop a valid and reliable scale for the evaluation of preconception health behavior in women preparing for pregnancy. Methods: The initial strategy included a literature review, interviews, and construction of a conceptual framework. The preliminary items were evaluated twice for content validity by experts, and modified two preliminary investigations. Participants in the 2 main investigations and the confirmation investigation were tested for reliability and validity of the preliminary scale in women preparing for pregnancy. The data were analyzed for different items exploratory and confirmatory factors. Results: The 5-point Likert scale consisted of 6 factors and 27 items. The 6-factors included 'hazardous substance factor,' 'medical management factor,' 'rest and sleep factor,' 'stress management factor,' 'information acquisition factor,' and 'resource preparation factor.' Goodness of fit of the final research model was very appropriate and based on the following measures: Q=1.98, comparative fit index=.91, Tucker-lewis index=.89, standardized root mean square residual=.07, and root mean square error of approximation=.07. The criterion validity was .64. The reliability coefficient was .92 and the test-retest reliability was .61. Conclusion: The study findings indicate that the scale can be used for the development of nursing interventions to promote preconception health behavior in women preparing for pregnancy.

Objective : The efficacy of sciatic nerve decompression via transgluteal approach for entrapment of the sciatic nerve at the greater sciatic notch, called piriformis syndrome, and factors affecting the surgical outcome were analyzed. Methods : The outcome of pain reduction was analyzed in 81 patients with sciatic nerve entrapment who underwent decompression through a transgluteal approach. The patients were followed up for at least 6 months. The degree of pain reduction was analyzed using a numerical rating scale-11 (NRS-11) score and percent pain relief before and after last follow-up following surgery. Success was defined by at least 50% reduction in pain measured via NRS-11. To assess the degree of subjective satisfaction, a 10-point Likert scale was used. In addition, demographic characteristics, anatomical variations, and variations in surgical technique involving sacrotuberous ligamentectomy were analyzed as factors that affect the surgical outcome. Results : At a follow-up of 17.5±12.5 months, sciatic nerve decompression was successful in 50 of 81 patients (61.7%), and the pain relief rate was 43.9±34.17. Subjective improvement based on a 10-point Likert scale was 4.90±3.43. Among the factors that affect the surgical outcome, only additional division of the sacrotuberous ligament during piriformis muscle resection played a significant role. The success rate was higher in the scarotuberous ligementectomy group (79.4%) than in the non-resection group (42.6%), resulting in statistically significant difference based on average NRS-11 score, percent pain relief, and subjective improvement (p<0.05, independent t-test). Conclusion : Sciatic nerve decompression is effective in pain relief in chronic sciatica due to sciatic nerve entrapment at the greater sciatic notch. Its effect was further enhanced by circumferential dissection of the sciatic nerve based on the compartment formed by the piriformis muscle and the sacrotuberous ligament in the greater sciatic notch.

Objectives The purpose of this study is to investigate pain reduction and treatment satisfaction of patients with rib fracrture treated with Soyeom pharmacopuncture therapy under ultrasonic guided - thoracic paravertebral space (TPVS), and also compare to the patients with non-guided pharmacoacupuncture. Methods We studied medical records of 6 patients hospitalized with rib fractures were analyzed retrospectively at department of Korean Medicine Rehabilitation from March 1, 2019 to May 31, 2019, The 3 patients had performed the treatment of Soyeom pharmacopuncture therapy on TPVS under ultrasonic guidance with Korean Medicine treatment (such as herbal medicine, acupuncture, moxabustion, etc) and the other 3 patients had performed the treatment of Soyeom pharmacopuncture therapy on TPVS through non-guided. We used numeric rating scale to assess improvements in pain and the five-point likert scale was used to assess treatment satisfaction. Statistical analysis was carried out using the IBM SPSS Statistics 24 program. Results The purpose of this study is to investigate pain reduction and treatment satisfaction of patients with rib fracrture treated with Soyeom pharmacopuncture therapy under ultrasonic guided - TPVS, and also compare to the patients with non-guided pharmacoacupuncture. Conclusions After analyzing 6 studies, we could imply that the treatment of Soyeom pharmacopuncture therapy on TPVS under ultrasonic guidance could be more effective on pain reduction and improvement of treatment satisfaction with rib fracture compared to those who were treated with non-guided pharmacoacupuncture.

Objectives: The Korean Dizziness Handicap Inventory (KDHI), which includes 25 patient-reported items, has been used to assess self-reported dizziness in Korean patients with Parkinson disease (PD). Nevertheless, few studies have examined the KDHI based on item-response theory within this population. The aim of our study was to address the feasibility and clinimetric properties of the KDHI instrument using polytomous Rasch measurement analysis. Methods: The unidimensionality, scale targeting, separation reliability, item difficulty (severity), and response category utility of the KDHI were statistically assessed based on the Andrich rating scale model. The utilities of the orderedresponse categories of the 3-point Likert scale were analyzed with reference to the probability curves of the response categories. The separation reliability of the KDHI was assessed based on person separation reliability (PSR), which is used to measure the capacity to discriminate among groups of patients with different levels of balance deficits. Results: Principal component analyses of residuals revealed that the KDHI had unidimensionality. The KHDI had satisfactory PSR and there were no disordered thresholds in the 3-point rating scale. However, the KDHI showed several issues for inappropriate scale targeting and misfit items (items 1 and 2) for Rasch model. Conclusions: The KDHI provide unidimensional measures of imbalance symptoms in patients with PD with adequate separation reliability. There was no statistical evidence of disorder in polytomous rating scales. The Rasch analysis results suggest that the KDHI is a reliable scale for measuring the imbalance symptoms in PD patients, and identified parts for possible amendments in order to further improve the linear metric scale.

The purpose of this preliminary study was to investigate the validity of the 'Attachment Q-set' as a measuring tool for 5 years attachment stability. The subjects comprised 18 boys and 15 girls aged 5 in a daycare center in G city, in Kyongnam. The instruments used in this study were 'Attachment Q-set', ASCT, and IPPA-R. Based on experts' rating, the Q-set was modified, reducing it from 90 to 75 items, and used a Likert 5-points scale. ASCT scores as well as types were compared with the scores of the Q-set and IPPA-R. The attachment type was classified into either secure or insecure. The IPPA-R score of the secure infants was significantly higher than the insecure, and correlated with the ASCT score. However, there was no significant correlation between the Q-set score with the attachment types or the ASCT scores. The Q-set scores were partially correlated with the IPPA-R. This results were discussed in terms of the Q-set's invalidity for rating attachment levels of 5 years as well as the limitations imposed by the subjects' restrictive numbers.
