The purpose of this study is to evaluate the effects of multiple cooling systems and different drinking water temperatures (DWT) on the performance of sows and their hair cortisol levels during heat stress. In this study, the effect of four different cooling systems: air conditioner (AC), cooling pad (CP), snout cooling (SC), and mist spray (MS), and two DWT, namely low water temperature (LWT) and high water temperature (HWT) on 48 multiparous sows (Landrace × Yorkshire; 242.84 ± 2.89 kg) was tested. The experiment is based on the use of eight replicas during a 21-days test. Different behaviors were recorded under different cooling treatments in sows. As a result, behaviors such as drinking, standing, and position change were found to be lower in sows under the AC and CP treatments than in those under the SC and MS treatments. Lying behavior increased under the AC and CP systems as compared with that under the SC and MS, systems. The average daily feed intake (ADFI) in sows and weight at weaning in piglets was higher under the AC, CP, and LWT treatments than under the SC, MS and HWT treatments. Sows subjected to SC and MS treatment showed higher hair cortisol levels, rectal temperature, and respiratory rate during lactation than those under AC and CP treatments. Hair cortisol levels, rectal temperature, and respiratory rate were also higher under the HWT than under the LWT treatment. As per the results of this study, the LWT has no significant effect on any of the behavioral factors. Taken together, the use of AC and CP cooling treatment is highly recommended to improve the behavior and to reduce the stress levels in lactating sows.

Purpose: Eating behaviors are influenced by food environments, such as availability and/or accessibility of healthy food options. In this study, we examined the relationship between healthy eating-out options and the intention to eat healthily in adults residing in Daqing, China, using an extended theory of planned behavior (TPB). Methods: Data were collected via an online survey conducted from April to May 2021 using a previously validated questionnaire in Daqing. A total number of 308 subjects aged 18-64, either Daqing oilfield workers or their family members were eligible and finally included in the analysis. The relationships among the attributes and the quality of healthy eating-out options, the three major constructs of TPB, and the intentions of healthy eating were examined using multiple linear regression analyses. Results: Subjective norms (p = 0.049) and perceived behavioral control (PBC) (p = 0.000) were significantly related to the healthy eating intention. The quality and attributes of the food served statistically significantly explained the intention to eat healthily. After controlling for age, sex, and body mass index, not the quality but the attributes of food served (p = 0.037), subjective norms (p = 0.016), and PBC (p = 0.000) had a significant relationship with the intention to eat healthily. The model explained 83.7% of the variance. Conclusion: The healthy eating-out choices, along with subjective norms and PBC of TPB, may be a potential determinant of healthy eating intention among Chinese adults living in Daqing, China. Policy implications have highlighted that not only the personal intention to eat healthy foods, but also the available healthy food environment may be important for the choice of healthy options by the population of interest. Therefore, building an environment for healthy eating choices and campaigns aimed at increasing consumer awareness of healthy eating are equally important for a smart eating choice.

Objectives: Understanding the factors influencing mothers' decision to breastfeed their infants is essential to formulate effective breastfeeding interventions. This study explored the determinants of optimal breastfeeding indicators in Indonesia. Methods: We used the 2017 Indonesia Demographic and Health Survey to analyze factors associated with early initiation of breastfeeding, exclusive breastfeeding (EBF), and continued breastfeeding at 1 year (CBF-1) and 2 years (CBF-2). Multivariate logistic regression models were used to examine bio-demographic, socio-cultural, and behavioral characteristics associated with breastfeeding after considering the survey design effect. Results: The risk of delayed breastfeeding initiation was higher among infants who were born smaller, first-born children, were delivered via cesarean delivery, and did not have immediate skin-to-skin contact (p<0.01). Infant's age, birth pattern, household wealth index, and the mother's occupation and smoking status were predictors of EBF (p<0.05). CBF-1 was less common among first-time mothers and those working in the non-agricultural sector, mothers from wealthier families, and mothers who had cesarean deliveries (p<0.01). Infant's age was negatively associated with CBF-2 (adjusted odds ratio [aOR], 0.85; 95% confidence interval [CI], 0.74 to 0.99). Mothers attending college were less likely to practice CBF-2 than those with no education or primary education (aOR, 0.45; 95% CI, 0.26 to 0.77). The absence of postnatal visits was a risk factor for CBF-1 and CBF-2 (p<0.05). Conclusions: Breastfeeding interventions in Indonesia should pay particular attention to at-risk groups such as women from wealthier families, working outside the agricultural sector, and with a higher education level. Nutrition-sensitive programs (e.g., postnatal care and smoking cessation) should also be encouraged.

Objective : The purpose of this study was to examine the influence of subscales of emotional intelligence on empathy in first-year medical students. Methods : A total of 215 first-year medical students were eligible for this study. Demographic factors (age, sex, and medical school entrance type) and measures for emotional intelligence and empathy, such as the Wong and Law Emotional Intelligence Scale and the Interpersonal Reactivity Index, were included in the survey. The relationship between emotional intelligence and empathy was analyzed by multiple linear regression, adjusting for age, sex, and entrance type. Results : The female students' level of emotional intelligence was higher than the male students for the self-emotional appraisal (p=0.029) and others' emotional appraisal (p=0.006) subscales. Meanwhile, the graduate-entry students scored higher for the use of emotion (p<0.001) and regulation of emotion (p=0.010) subscales than the direct-entry students. For empathy, the female students revealed a higher score in empathic concern (p=0.009) than the male students, and graduate-entry students scored higher than the direct-entry students in perspective taking (p=0.004) and empathic concern (p<0.001). The multiple linear regression analysis has identified significant influences of subscales of emotional intelligence on empathy: others' emotional appraisal on perspective taking (p<0.001), self-emotional appraisal (p=0.035) and regulation of emotion (p=0.023) on fantasy, others' emotional appraisal (p<0.001) and use of emotion (p=0.020) on empathic concern, and self-emotional appraisal (p=0.033) and regulation of emotion (p<0.001) on personal distress. Conclusion : This study's findings suggest that emotional intelligence may affect empathy in medical students, which can have implications for developing educational strategies to enhance empathetic attitudes in medical students.

Objective: The daily maximum temperature and seawater level continuously increase as global warming continues. We examined the adaptability and production performance of heat-stressed goats with a supply of low-saline drinking water. Methods: Twelve Kacang and Kacang Etawah cross goats were exposed to two climatic conditions (control, 25℃ to 33℃, 83% relative humidity [RH], temperature humidity index [THI]: 76 to 86; and hot environment, 26℃ to 39℃, 81% RH, THI: 77 to 94) and two salt levels in drinking water (0% and 0.4% NaCl). The experimental design was a Latin Square (4×4) with four treatments and four periods (28 days each). Results: Temperature of the rectal, skin, and udder, and respiration rate rose, reached a maximum level on the first day of heat exposures, and then recovered. Plasma sodium rose at 0.4% NaCl level, while the hot environment and salinity treatments increased the drinking water to dry matter (DM) intake ratio. Water excretion was elevated in the hot environment but lowered by the increase in salinity. Total lying time increased, whereas change position frequency decreased in the hot condition. Lying and ruminating and total ruminating time increased and explained the enhanced DM digestibility in the hot conditions. Conclusion: The goats exhibited a high level of plasma sodium as salinity increased, and they demonstrated physiological and behavioral alterations while maintaining their production performances under increasing daily maximum temperatures.

The purpose of this study is to classify elderly patient in long-term care facilities using RUG(Resource Utilization Group)-III. It is designed by measuring patient medical characteristics and medical staff time. Elderly patients are classified into 7 categories by clinical(medical and behavioral) hierarchical typology of patients. Through the tertiary split, all 44 groups are formulated. This classification is explained by each patient resource(staff time) utilization level which is called CMI(Case-Mix Index). Major findings are as follows; 1. The objects in this study were classified into 35 groups out of 44 groups. The most frequent category is clinical complex category(CCC; 38.9%). And extensive service category(ESC; 18.8%), reduced physical function category(RPC; 13.1%), special rehabilitation category(SRC; 12.8%), and impaired cognitive category(ICC; 0.00%) are followed. 2. The mean of total CMI was $1.02{\pm}0.36$, ranging from 0.68 to 1.44(1 vs 2.12). The mean of CMI of SRC is only 1.17 which should be the highest. The means of ESC and see are equally 1.20. The means of CMI of CCI, ICC, BPC, and RPC were 0.90, 0.75, 0.83 and 0.96, respectively. 3. The validity of this classification was tested. Trend-test using Regression Analysis was done in the secondary split level. SCC, CCC, ICC, and RPC which covered 68.4% of this research objects showed linear trend of CMI in interim classification. This results were statistically significant. 4. In clinical hierarchy, the trend were showed linearity. But the multiple comparison of categories using Scheffe-test showed that SRC, ESC and see had same level of CMI means and CCC and ICC, too. This results were statistically significant. Classifying elderly patients with RUG-III, the results showed partly linear trend in clinical hierarchy and in interim classification in conclusion. But, in clinical hierarchy, it was failed to show the consistent order of CMI. It can be explained by two reasons. One is that this research subjects were overlapped in each clinical hierarchy group. And the other is that the some of the characteristics for clinical hierarchy is not appropriate for them. For the further study, it needs to have proper sample size and to modify RUG-III to K-RUG to consider our.. medical environment.

Background : Interstitial cystitis is a disorder of the bladder characterized by urgency and frequency of urination, and pelvic pain. The cause of interstitial cystitis is not clear. Modern medical treatments include behavioral therapy, medication, intravesical infusion therapy, and surgical treatment, but the goal of treatment is based on symptom relief rather than a cure. According to a recent report, in an animal model, oriental medicine treatment, Yukmijihwang-tang improved the symptoms of interstitial cystitis. However, clinical studies and experimental research are lacking. Objectives : In this study, We investigated Chuknyojetong-tang, acupuncture, moxibustion and bee venom effect on interstitial cystitis. Methods : We targeted 25 patients diagnosed with interstitial cystitis at the university hospital and treated them for more than one month. We used acupuncture, Chuknyojetong-tang, and bee venom. The effects were evaluated using ICSI and ICPI at the begin of treatment and at the end of treatment. Results : All of the 25 patients were female, average age was $53.3{\pm}13.5$ years, and the average month of disease-duration was $69.0{\pm}59.8$. The duration of treatment was $8.0{\pm}5.4$ months, and 60% of patients were improved. After treatment, we used correlation coefficient method, multiple regression analysis. ICSI difference increased as treatment period increased. ICPI difference increased as age decreased. Total difference also increased as treatment period increased. These results imply that treatment effect was improved. Conclusions : These findings suggest that oriental medicine therapy using Chuknyojetong-tang, acupuncture, moxibustion, and bee venom would be very effective on interstitial cystitis.

Parvalbumin occurs in various types of cells in the retina. We previously reported parvalbumin distribution in the inner nuclear layer of bat retina. In the present study, we identified the parvalbumin-immunoreactive neurons in the ganglion cell layer of the retina of a bat, Rhinolophus ferrumequinum, and investigated the distribution pattern of the labeled neurons. Parvalbumin immunoreactivity was found in numerous cell bodies in the ganglion cell layer. Quantitative analysis showed that these cells had medium to large-sized somas. The soma diameter of the parvalbumin-immunoreactive cells in the ganglion cell layer ranged from 12.35 to 19.12 ${\mu}m$ (n=166). As the fibers in the nerve fiber layer were also stained, the majority of parvalbumin-immunoreactive cells in the ganglion cell layer should be medium to large-sized retinal ganglion cells. The mean nearest neighbor distance of the parvalbumin-immunoreactive cells in the ganglion cell layer of the bat retina ranged from 59.57 to 62.45 ${\mu}m$ and the average regularity index was 2.95 ${\pm}$ 0.3 (n=4). The present results demonstrate that parvalbu-min is expressed in medium to large-sized retinal ganglion cells in bat retina, and they have a well-or-ganized distributional pattern with regular mosaics. These results should be important as they are applicable to a better understanding of the unsolved issue of a bat vision. This data will help to provide fundamental knowledge for the better understanding of the unique behavioral aspects of bat flight maneuverability.

This study was designed to determine whether cognitive impairment was evident in patients with SLE. Also, it aimed to examine the association of cognitive impairment with other clinical variables. The subjects consisted of 20 patients with mildly active SLE and 20 healthy controls. Methods : A total of 20 SLE patients and 20 normal controls completed a computerized neuropsychological test battery using Vienna Test System. These included Cognitrone test, Continuous attention test, Corsi block tapping test, Standard progressive matrices. Also, neuro-behavioral cognitive status examination was done. The symptom severity of depression was measured with Beck Depression Inventory, Hamilton Depression Rating Scale, and current medications were documented. Disease activity was rated using the SLE diasease activity index (SLEDAI). Results : SLE patients had poorer performance than normal controls on the tests of Cognitrone, attention, nonverbal IQ and memory, independent of age, education, disease activity, steroid use and depression status. Conclusion : Cognitive dysfunction was not uncommon in ambulatory SLE patients as measured by standardized neuropsychological tests. It seemed to occur independently of various clinical variables. These findings would suggest that cognitive dysfunction in SLE may be explained by reflecting subclinical central nervous system(CNS) involvement, rather than coexisting psychological distress due to chronic illness or side effect of medication.

Purpose: This study was performed to evaluate the effect of powered toothbrush with a wireless remote display on the subjective and objective oral hygiene improvement. Methods: One hundred and fifteen subjects in healthy or mild gingivitis status between the ages of 20 and 90 were recruited and reviewed for study inclusion criteria. At first visit, 115 pre-screened subjects filled in the questionnaire form which consisted of demographic factors, behavioral factors (smoking, alcohol consumption), toothbrushing habits (brushing time and frequency), self-reported oral health status, and self-satisfaction. Baseline clinical indices (Plaque index, Gingival index) were also recorded by a periodontist. Subjects were instructed how to use powered toothbrush with a wireless remote display, and were provided with it. Thirty days after first visit, 90 subjects returned for the second assessment by self-reported questionnaire form and professional clinical checkup. Statistical analysis was performed using paired t-test for the difference between baseline and second visit data. The relationship among variables was examined with chi-square test and Fisher' s exact test. Results: Significant differences were not found on self-reported satisfaction related with sex, smoking, alcohol consumption (P<0.05). Self-reported tooth brushing habit was improved in the aspect of brushing time and frequency. Significant differences were found on the self-reported oral health status, self-satisfaction, and clinical indices between the baseline and second visit data (P<0.01). Clinical indices were significantly reduced after using powered toothbrush with a wireless remote display (P<0.01). No adverse reactions were reported during the study period. Conclusions: Powered toothbrush with a wireless remote display successfully promoted oral hygiene from the subjective and objective viewpoint after 30 days of home usage.
