PURPOSE: This study examined the efficacy of an interferential current (IFC) treatment on the improvement of pain, disability, and quality of life in stroke patients with lumbago. METHODS: A double-blind, randomized clinical trial was conducted on 40 stroke patients with lumbago. The patients were allocated randomly into two groups: the IFC treatment group (n= 20) and the placebo treatment group (n= 20). The IFC group received 30 minutes of IFC treatment on the lumbar region, while the placebo group received IFC treatment but without real electrical stimulation. The intervention was administered five days a week for four weeks. The primary outcomes of pain intensity were measured using a visual analogue scale. The secondary measurements included the Barthel Index, Oswestry Disability Index (ODI), and health-related quality of life (HRQoL). RESULTS: The measurements were conducted before and after the two-week intervention period. Compared to the placebo treatment group, the IFC treatment group showed significantly greater improvement in the pain intensity (p<.05), ODI (p<.05), and SF-36 (p<.05) at the end of the intervention. No significant differences in the Barthel Index were found between the two groups. CONCLUSION: These findings show that an IFC treatment can improve pain, functional ability, and quality of life, highlighting the benefits of somatosensory stimulation from IFC in stroke patients with lumbago.

It is important to examine patients' subjective evaluation as well as objective measures and clinician's rating to assess voice disorders. This study aimed to evaluate validity and reliability of Korean-version of Voice Handicap Index (KVHI) and Voice-Related Quality of Life (KVQOL) with 113 adults with voice disorders and 111 normal adults. Content validity was verified by three experienced speech-language pathologists. Concurrent validity was revealed by examining the correlation among KVHI, KVQOL, and Voice Rating Scale as well as item discrimination coefficients. Total scores of KVHI and KVQOL of adults with voice disorders were significantly different from those of normal adults. Test-retest reliability and internal consistencies were significantly high in both KVHI and KVQOL. Correlations among scores of each subscale and total score were also significantly high in each tool. The study revealed that KVHI and KVQOL are suitable tools to be used in clinics and research areas in Korea, which can subjectively evaluate the effects of voice disorders on daily life as well as on quality of life.

This study was conducted to examine the effects of a healthy dietary life and purchase of environmental-friendly food materials according to a mother's lifestyles of health and sustainability (LOHAS) attitudes. The subjects consisted of 295 mothers. The findings are summarized as follows. The mother's LOHAS attitude index averaged 3.39 points out of 5 points. High LOHAS attitude items were "I participate actively in separating the trash collection" (4.16 points), and "I recycle dresses that I do not wear by taking them to the recycling center" (4.08 points). In contrast, LOHAS attitude items for "I do community service activity on the weekend" (2.57 points), and "I try to serve in the local community" (2.63 points) scored very low. A high LOHAS behavior index occurred for mothers who were "resource saving", whereas "social welfare" scored low. Mother's intention to purchase environmental-friendly food materials averaged 3.61 points. Mother's health dietary life attitude score averaged 3.52 points. When age, monthly income, and the environmental-friendly food materials purchase ratio of the mother was high, the health dietary life performance was high. The LOHAS attitude index of mothers had an impact on the purchase intention of environmental-friendly food materials in resource saving and environmental-friendly oriented propensity groups. The LOHAS attitude index of mothers impacted healthy dietary life in environmental-friendly, family and health oriented propensity groups.

The genus-level biotic index of benthic macroinvertebrates (Benthic Macroinvertebrates Genus Index, BMGI) was developed and applicated based on the data collected from 13,347 sampling units of 814 sites from 2010 to 2021 in Korea. Tolerant values of 274 indicator taxa were established by analyzing the relationship between the relative frequency and abundance of indicator taxa and the water quality index considering biochemical oxygen demand (BOD₅), total suspended solids (TSS), and total phosphorus (T-P). BMGI showed a slightly higher correlation with water quality than the species-level biotic index (Benthic Macroinvertebrates Index, BMI) that was developed and applied in Korea. Although the BMGI does not contain species-level information, the reason why BMGI shows higher applicability than BMI seems to be due to the increase in the number of indicator taxa and the decrease in the misidentification of immature aquatic insects. The coefficient of determination in multiple regression with BOD₅, TSS, and TP for BMGI was 0.62 in the long-term averaged data of 814 sites, and the standardized coefficient of BOD₅ was -0.46, TSS was -0.17 and T-P was -0.21, respectively. As a result of the evaluation by BMGI, of the 814 sites, 38% were in good, 25% in fair, and 37% in poor condition.

Purpose. In this study, we aim to clarify the correlation between happiness, appearance, and happiness index among many happiness factors based on the influence of quality of life on the quality of life and the affect of appearance on the happiness index. Methods. We conducted a self - filling questionnaire survey for college students in Busan from March 30 to May 10, 2017, and analyzed 392 copies of the 412 questionnaires, excluding 20 inappropriate copies. In the questionnaire, categorical data were analyzed by frequency and percentage (%) using the SPSS program (ver. 23.0, Chicago, Illinois, USA) by examining 11 items of general characteristics, successive data are presented as mean standard deviation. Results. The higher the grades, the better the dating. Women(3.32) are more likely than men(2.74) at the appearance interest(p>0.001) and the higher the grades, the better. If it's dating someone else, higher than not to do at the appearance interest and all of the questions showed higher interest in appearance. Also there was a high percentage of thought'My life is ideal in all aspects'If it's dating someone else, higher than not to do (p=0.007) Conclusion. At present, There is a high interest in the appearance of dating. In addition, the happiness index according to the current resentment status was higher in both the single item happiness index and the 5 item happiness index, and was significant in the item "My life is ideal in all aspects". Therefore, it is related to the happiness index as well as the appearance interest. Finally, whether or not dating and appearance interest play a role in raising the happiness of the individual.
