Purpose: This study investigated the impact of ametropia and myopia on health-related quality of life (QoL) measures in elementary schoolers. Methods: Elementary school children of 92 aged 12 to 13 were divided into emmetropia and myopia groups by spherical equivalent. Then myopia was classified into the low, moderate and high myopia groups. Vision-related QoL scores were determined using PedsQL 4.0 (Pediatric Quality of Life Inventory) with physical health (8 items), emotional functioning (4 items), social functioning (5 items) and school functioning (5 items). Results: The total QoL score in the myopia group appeared lower than that in the emmetropia group, however the difference was not statistically significant (p>0.05). When it comes to physical health (running or exercising) and social functioning (getting along with friends or being teased)-related questions, the QoL score in myopia was low compared with the emmetropia group (p<0.05). High myopia showed a low score in physical health items but there was no significant difference in overall QoL scores in comparison with other groups (p<0.05). Conclusions: Refractive errors does not have a great impact on the total health-related QoL in elementary school children but it causes discomfort in physical health and social functioning.
This correlational study sought to find the relationship among women's health status and the level of importance & performance of postpartal care. One hundred thirty three women who live in Seoul and rural area including hospitalized in a general hospital and midwifery clinic were studied from 1st April, 1998 to 25th April, 1998 for 25 days. Data analysis consisted of frequency, percentage, Pearson Correlation Coefficiency, t-test, ANOVA and Sheffe test as a post hoc, using SPSS. The results of analysis were as follows ; mean age of respondents was 31.9 years and mean number of children was 1.8. The most of family type was nuclear family and lived int apartment. Mean frequency of pregnancy was 2.7 times and most women delivered at local clinic, general or University hospital. Mean period of after delivery was 53.7 month. The level of importance and performance of traditional postpartal care (Sanhujori) was more higher than hospital postpartal care. The level of importance, performance of postpartum care and health status had significant relationship. The higher level of importance was, & the higher level of performance was higher, and the higher degree of health status. The factors related to health status were postabortal sahujori period after abortion, nuclear family, the evaluation of sahujori, whether women and followed the caregiver's advice well or not and whether they have physical symptoms or not, at the level of $5{\sim}0.1%$ of significance statistically. The factors related to the level of importance of postpartal care were the number of child, present health status and health status of pre-post of delivery, deliver place and the opinion of effective postpartum care method at the level of $5{\sim}0.1%$ of significance statistically. The factors related to the level of performance of postpartal care were delivery place, the opinion of whether they can do at the hospital or not and whether they have physical symptom or not at the level of $1{\sim}0.1%$ of significance statistically. In conclusion, this finding reconfirmed the relationship among women's health status and the postpartal care. It provides a challenge to the health professional caregivers to research continually and repeatedly and confirm the conceptual model of Sanhujori, reestablish effective and integrative postpartal caring system which contains oriental and western paradigm for women's life long health toward the 21C.
Microbial contamination levels in commercial strawberry juices were examined for sanitary indication bacteria, such as aerobic plate count (APC), coliforms, and Escherchia coli, and pathogenic bacteria such as E. coli O157:H7, Salmonella spp., Staphylococcus aureus, and Listeria monocytogenes. APC and coliform count ranged 0-5.2 and $0-2.8\;log_{10}\;CFU/(mL,\;g,\;100cm^{2},\;hand)$, respectively, and 80% strawberry juices were contaminated with E. coli and S. aureus, detected at 19%, was found in employee's hands, strawberries, and strawberry juices, whereas E. coli O157:H7, Salmonella spp, and L. monocytogenes were not detected. These results will provide microbiological information for introduction of Hazard Analysis Critical Control Point (HACCP) system in juice shops.
Staphylococcus aureus is spread worldwide and can result in food poisoning outbreaks. Among samples collected from soil, water, protected houses, packing houses, employees, strawberries, and leaves, and analyzed for S. aureus contamination, 16% samples 'showed S. aureus contamination, particularly on employees' hands, scissors, and strawberries. Examination of enterotoxins A, B, and C genes of S. aureus by PCR revealed sea and seb in 92 and 38% of total strains, respectively, whereas sec was not detected. In conclusion, implementation of Good Agricultural Practice is necessary for preventing food-borne diseases of staphylococcal origin, thereby ensuring the safety of farm-to-table products.

Objective: The purpose of this study was to identify the predictors and frailty level in the frail elderly receiving home visiting health care services. Methods: The subjects were 177 frail elders aged over 65 registered in the home visiting health care services of three public health centers in Daegu. The data collection was performed from June 9 to June 24, 2015. This study used descriptive statistics, t-test, ANOVA, scheffe test and stepwise multiple regression by SPSS Win 18.0 program. Results: The mean of the frailty score was 10.05 (${\pm}4.52$). Age and life satisfaction were the significant factors related to the frailty score in frail elderly. Health promotion behavior, empowerment, social participation and perceived health status had a negative correlation with the frailty score. Thirty seven point four percent of the variance in the frailty score can be explained by perceived health status (${\beta}=-0.398$, p<0.001), health promotion behavior (${\beta}=-0.251$, p<0.001) and age (${\beta}=0.232$, p<0.001)(Cum $R^2=0.374$, F=25.744, p<0.001). Perceived health status was the most important factor related to the frailty score in our study. Conclusions: An integrative care program which includes these significant variables of subjects is essential to prevent the deterioration of frailty in frail elderly.

Objectives: The purpose of this study was to identify the level of quality of life and related factors in the elderly with dementia living in their houses of rural area who are receiving dementia partners' supporting activities. Methods: The study participants were 55 elderly people with dementia living in their houses who were participating in the dementia partner pilot project among those registered in the public health center in one area and 55 dementia partners. Data were analyzed by independent t-test, ANOVA, Pearson correlation analysis and multiple regression analysis. Results: The factors that had a significant effect on quality of life included depression to predict the quality of life in the elderly with dementia. And its explanatory power was 46.8%. Conclusions: Based on these results, it is crucial not only to maintain physical functions but also to decrease depression by emotional support activities so as to enhance their quality of life, therefore, it is required to develop and apply the integrative supporting programs in rural area. From the result that dementia partner's self-compassion would lower the depression in the elderly with dementia significantly, it is considered to develop the programs to enhance dementia partners' self-compassion.
Hepatocellular carcinoma (HCC) is the second leading cause of cancer-related mortality worldwide, necessitating novel therapeutic strategies. The chemotherapeutic agents used to treat HCC patients are toxic and have serious side effects. Therefore, we investigated the efficacy of anticancer drugs that reduce side effects by targeting tumor cells without causing cytotoxicity in healthy hepatocytes. Berberine, an isoquinoline alkaloid derived from plant compounds, has emerged as a potential candidate for cancer treatment due to its diverse pharmacological properties. The effect of berberine on HepG2 cell viability was determined using the 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyl tetrazolium bromide assay. HepG2 cell proliferation was determined through a colony-forming assay. The effects of berberine on HepG2 cell migration were evaluated using a wound-healing assay. Berberine inhibited the proliferation of HepG2 cells, as well as colony formation and migration. Berberine treatment increased the expression of autophagy-related genes and proteins, including Beclin-1 and LC3-II, and elevated the activities and mRNA expression of Caspase-9 and Caspase-3. Additionally, in experiments utilizing the Cell-Derived Xenograft animal model, berberine treatment reduced tumor size and weight in a concentration-dependent manner. These results demonstrate the potential of berberine as a versatile anticancer agent with efficacy in both cellular and animal models of hepatocellular carcinoma. The findings herein shed light on berberine's efficacy against HCC, presenting opportunities for targeted and personalized therapeutic interventions.
Objectives: Periodic leg movements in sleep (PLMS) might be subdivided based upon whether or not they are associated with visible EEG microarousals (MA). MA is considered to be responsible for nonrestorative sleep and daytime fatigue. The American Sleep Disorders Association's (ASDA) scoring rules for MA based on visual analysis of the EEG changes suggest that MA should last more than 3 seconds. However, it has been suggested that visual analysis may not detect some changes in EEG activity. This study is aimed at measuring changes in EEG spectra during PLMS without MA in order to better understand the arousing response of PLMS. Methods: Ten drug-free patients (three men and seven women) diagnosed with PLMS by polysomnography were studied. Spectral analysis of the EEG was performed in each patient on 30 episodes of PLMS without MA, chosen randomly across the night in stage 2 non-REM sleep. We applied stricter criteria for MA compared to ASDA, by defining it as a return to alpha and theta frequency lasting at least 1 second. Results: The mean PLMS index was $16.7{\pm}10.0$. The mean PLMS duration was $1.3{\pm}0.7$ seconds. Comparison of 4-second EEG activity both before and after the onset of PLMS without MA using independent t-test showed that the movements were associated with significant increase of relative activity in the delta band (p=0.000) and significant decrease of activity in the alpha (p=0.01) and sigma (p=0.000) bands. No significant decrease in the theta (p=0.05), beta (p=0.129), or gamma (p=0.062) bands was found. Conclusion: PLMS without MA was found to be associated with EEG change characterized by increase in the delta frequency band. This finding seems to be compatible with the hypothesis of an integrative hierarchy of arousal responses of Sforza's. Considering that the subjects had lower PLMS index and shorter PLMS duration than those of the previous study, it is suggested that an even less severe form of PLMS without MA could induce neurophysiologic change, which may potentially be of clinical significance.
This study sought to find out the level of perception of postpartal care and the meaning and opinion of traditional postpartal care (Sanhujori) from health professional. The subjects were 188 health professionals who work at University hospital, clinics, Oriented clinics, and midwifery clinics in Seoul and Chung-Buk, Korea. Data were collected from 8th April, 1999 to 6th May, 1999. The data were analyzed through the SPSS program by use of frequency, percentage, t-test, ANOVA and Scheffe test as a post hoc contrast, $x^2$-test, and stepwise multiple regression. The results of the study were as follows: mean age of the subject was 33.0 years and female was 58.0%. Occupation of the subject was nurse 28.7%, doctor 22.3%, midwife 21.3 Korean Oriental doctor 27.0%. Mean period of career was 7.6 years and the subject who experienced Sanhujori was 54.3%. The subject who did not know 6 principles of Sanhujori was 73.9%. In the opinion on traditional Sanhujori method 68.1% of respondents expressed that Sanhujori is scientific postpartal care which fits Korean people's physical constitution and culture. On the opinion of effective postpartal care in 97.9% of respondents expressed that it is to in hospital postpartal care and traditional Sanhujori perform it according to Korean culture constitution. On the opinion of Sanhujori, 96.6% of respondents expressed that it is necessary to understand Sanhujori with consideration which was adapted to Oriental culture and to verify it through continual study. On the opinion of the effect of the level of performance of Sanhujori upon women's health life, 43.2% of respondents expressed that the level of performance of Sanhujori has great effect on women's general health, including postpartal recovery, Sanhujori prevention, and so on. On the opinion of Sanhujori of women who undergo Caesarean operation, 57.7% of respondents expressed that women who undergo Caesarean operation perform Sanhujori with more attention. On the opinion of Sanhujori center (sanhujorwon), 56.3% of respondents expressed that the center is necessary for women's health and health professional are required to manage the center scientifically. On considering the level of importance of post care according to occupation, midwife showed highest level of importance of traditional Sanhujori doctor the lowest level. Midwife showed the hi level of importance of postpartal care and K Oriental doctor showed the lowest level of importance of women's postpartal care. On considering the relationship between the level of importance of postpartal care and general characteristics, sex, career, clinical department and whether they know 6 principles of Sanhujori or not were statistically significant at the level of 5%. In the stepwise multiple regression analysis, the main influencing variables on the level of importance of postpartal care were occupation, sex, and clinical department. In conclusion, this finding confirmed that professionals were considering the traditional Sa importantly for women's health. Above all things necessary for health professional to integrate concept of traditional Sanhujori into practical nu intervention program, to apply it to profes practices in order to reestablish effective integrative postpartal caring system, and to Sanhujori scientific through performing continual research.

Objective: This study aimed to validate the risk stratification system (RSS) and biopsy criteria for cervical lymph nodes (LNs) proposed by the Korean Society of Thyroid Radiology (KSThR). Materials and Methods: This retrospective study included a consecutive series of preoperative patients with thyroid cancer who underwent LN biopsy, ultrasound (US), and computed tomography (CT) between December 2006 and June 2015. LNs were categorized as probably benign, indeterminate, or suspicious according to the current US- and CT-based RSS and the size thresholds for cervical LN biopsy as suggested by the KSThR. The diagnostic performance and unnecessary biopsy rates were calculated. Results: A total of 277 LNs (53.1% metastatic) in 228 patients (mean age ± standard deviation, 47.4 years ± 14) were analyzed. In US, the malignancy risks were significantly different among the three categories (all P < 0.001); however, CT-detected probably benign and indeterminate LNs showed similarly low malignancy risks (P = 0.468). The combined US + CT criteria stratified the malignancy risks among the three categories (all P < 0.001) and reduced the proportion of indeterminate LNs (from 20.6% to 14.4%) and the malignancy risk in the indeterminate LNs (from 31.6% to 12.5%) compared with US alone. In all image-based classifications, nodal size did not affect the malignancy risks (short diameter [SD] ≤ 5 mm LNs vs. SD > 5 mm LNs, P ≥ 0.177). The criteria covering only suspicious LNs showed higher specificity and lower unnecessary biopsy rates than the current criteria, while maintaining sensitivity in all imaging modalities. Conclusion: Integrative evaluation of US and CT helps in reducing the proportion of indeterminate LNs and the malignancy risk among them. Nodal size did not affect the malignancy risk of LNs, and the addition of indeterminate LNs to biopsy candidates did not have an advantage in detecting LN metastases in all imaging modalities.
