This study correlated changes in estradiol-l7$\beta$ ($E_2$), testosterone (T), 17$\alpha$,20-dihydroxy-4-pregnen-3-one (DHP), and vitellogenin (VTG) levels with changes in the gonadosomatic index (GSI) and ovarian histology during the annual reproductive cycle of the wild marbled sole, Limanda yokohamae. Synchronous oocyte development occurs in this fish. Ovary maturity was classified into four periods, based on histological observations: the spawning (December to February), post-spawning (February to April), recovery (May to August), and vitellogenic (September to November) periods. Seasonal changes in the GSI were inversely correlated with water temperatures and reflected the degree of ovarian maturity. Plasma VTG levels were correlated with changes in the GSI, which increased from September to a peak in January, and levels remained comparatively high until February. Estradiol-17$\beta$ was at baseline levels (<0.11 ng/mL) during the spring and summer, and peaked rapidly (1.55$\pm$0.445 ng/mL) from October to January. Plasma T and DHP levels had a similar profile; they rose markedly during the spawning period and remained low (or were not detectable) from spring through autumn. These data indicate that changes in plsama steroid hormones and VTG levels are correlated with the annual ovarian activity of the marbled sole. Based on these results and published reports, it appears that in this species DHP is the most important maturation-inducing steroid and that T is also related to final maturation.

This study was carried out to investigate consumption patterns of health functional foods (HFF) and analyze their related factors in male workers in order to provide basic data for appropriate understanding and optimal use of HFF. The subjects were 325 shipbuilding workers aged 20~50 in the Geoje area. About 84% of subjects reported that they were currently consuming or had experience of consuming HFF. The most commonly used type of HFF was vitamins (53.5%), followed by red ginseng (28.9%) and vegetable extract (15.4%). The major reasons for consuming and not-consuming HFF were 'to recovery from fatigue' (49.5%) and 'can not trust the effects' (39.4%), respectively. The intake period was 'less than 3 months' (35.5%), average monthly expense was 'less than 50,000 won' (49.1%), and purchase place was 'store of health functional foods' (32.2%) as the most common answers. The effects after consuming HFF were 'moderate' (51.3%) as the most common answer, and 16.1% of subjects experienced side effects, such as diarrhea, indigestion and nausea. Contributing factors for selecting and desire for future use of HFF were 'effectiveness' (52.2%) and 'when necessary' (67.8%) as the most common answers. Experience of using HFF was positively correlated with age (p<0.05), marital status (p<0.05), unbalanced diet (p<0.01), concern about health (p<0.05), and fear for disease (p<0.05). Purchase of HFF was positively correlated with fear of disease (p<0.01), whereas it was negatively correlated with frequency of exercise (p<0.05). The desire for future use of HFF was positively correlated with concern about health (p<0.05), fear of disease (p<0.01) and drinking (p<0.05). In conclusion, factors affecting consumption patterns of health functional foods (HFF) were age, marital status, unbalanced diet, concern about health, fear of disease and drinking.

The purpose of this study was to investigate the relationship between parents' behavior during picture-book reading and home literacy environment and their effects on toddlers' vocabulary. The subjects of the study were 46 toddlers and their parents. The MCDI-K(Im, 2002), Lee and Kim(2004)'s categories of Verbal Behaviors, the categories of Nonverbal Behavioral Analysis(Kim, 2005), and the Home Literacy Environment Index(Han, 2006) were used. The analysis of the collected data was guided by the research questions and involved the use of descriptive statistics, t-test and an analysis of relevant correlations. The results of this study were as follows; First, the toddlers' receptive vocabulary score was 1.2 times higher than the toddler's expressive vocabulary score. Second, the father's book reading behaviors and mother's book reading behaviors were quite similar, the most frequent types of behavior being the use of 'feedback', 'explanation', 'questioning' and 'pointing'. On the other hand, there was a significant difference between the reading behavior of the mother and father as regards the categories of 'linguistic attention ventilation', 'suggesting', 'directing(instructing)', 'expanding feedback', 'pointing' and 'gesture'. Mothers performed more of these behaviors than the fathers. Third, toddler's vocabulary scores were positively correlated with the mother's 'linguistic attention ventilation'. However, the mother's use of 'restriction' was negatively correlated with the toddler's vocabulary level. Toddler's vocabulary scores were positively correlated with the father's 'description', 'reasoning/predicting', 'questioning about function or action', 'demanding feedback' and 'pointing'. The toddler's vocabulary scores were also positively correlated with the relative abundance of home environment materials and the amount of time spent on parent-child home literacy activity.

Objective: The purpose of this study was to evaluate the relationship between quality of life (QoL) of the caregiver and disease severity with motor function in children with cerebral palsy (CP). Design: Cross-sectional study. Methods: Research data were collected in the Rehabilitation Clinic of Daegu University. The Gross Motor Function Measure (GMFM-88) and the functional independence measure (FIM) were used for assessment by three occupational therapists, and the 36-item short form health survey (SF-36) were applied to the caregivers. One hundred six caregivers of under 18 years who were diagnosed with CP completed a survey and interview. The caregivers' QoL was evaluated using Medical Outcomes Study SF-36. The children's motor function was scored using GMFM-88 in five dimensions: lying and rolling; sitting; crawling and kneeling; standing and walking, running and jumping and CP's FIM scores. Results: Out of the 8 domains of the Medical Outcomes Study SF-36, the "physical functioning", "physical role functioning", "mental health", and "bodily pain" domains were significantly correlated to "total" percentage scores of the GMFM-88 (p<0.05). In addition, the "mental health" domain was correlated to each subdomain of the GMFM-88, which includes, "lying and rolling", and "crawling and kneeling". Similarly, of Medical Outcomes Study SF-36, "physical functioning", "bodily pain", and "mental health" domains were significantly correlated with "transfer" and "locomotion" of FIM scores (p<0.05). Conclusions: This study showed that the QoL of the caregivers were well correlated with the motor function of children with CP. It is also important to support not only physical health but also psychological health of caregivers of children with CP, especially those with severe motor function.

Objectives: The purpose of this study was to examine the perception of dental hospital accreditation and the awareness and practice of infection control in dental hygienists. Methods: A self-reported questionnaire was completed by 238 dental hygienists working at dental hospitals in Gwangju Jeonnam and analyzed from October 24, 2016 to September 22, 2017. Data were analyzed with the independent t-test, one-way analysis of variance, Pearson's correlation analysis, and multiple regression analysis using the Statistical Package for the Social Sciences software, version 21.0. Results: Compared to non-accredited dental hospitals, all three variables were high for accredited dental hospitals. In accredited dental hospitals, healthcare accreditation expectancy effects correlated to awareness (r=0.407) and practice (r=0.533) of infection control, and awareness of infection control correlated to its practice (r=0.725). In non-accredited dental hospitals, healthcare accreditation expectancy effects correlated to awareness of infection control (r=0.239), and awareness of infection control correlated to its practice (r=0.481). Accredited dental hospitals showed healthcare accreditation expectancy effects (${\beta}=0.258$) and awareness of infection control (${\beta}=0.556$), and non-accredited dental hospitals were influenced by the number of employees (${\beta}=0.567$) and awareness of infection control (${\beta}=0.376$). Conclusions: It is necessary to develop efficient and systematic infection control programs to improve the awareness and practice of infection control in dental hygienists and patient's safety in the clinical field.

Aiming at the grouting treatment of water inflow in karst conduits, a visualized experiment system for conduit-type grouting blocking was developed. Through the improved water supply system and grouting system, and the optimized multisource information monitoring system, the real-time observation of diffusion and deposition of slurry, and the data acquisition of pressure and velocity during the whole process of grouting were realized, which breaks through the problem that the monitoring element is easy to fail due to slurry adhesion in conventional test system. Based on the grouting experiments in static and flowing water, the diffusion and deposition behavior of the quick-setting slurry under different working conditions were analyzed. The temporal and spatial variation behavior of the pressure and velocity were studied, and the blocking mechanism of the grouting were further revealed. The results showed that: (1) Under the flowing water condition, the counter-flow diffusion distance of slurry was negatively correlated with the flow water velocity and the volume ratio of cement and sodium silicate (C-S ratio), and positively correlated with the grouting volume. The slurry deposition thickness was negatively correlated with the flowing water velocity, and positively correlated with the grouting volume and C-S ratio. (2) The pressure increased slowly before blocking of the flowing water and rapidly after blocking in karst conduits. (3) With the continuous progress of grouting, the flowing water velocity decreased slowly first, then significantly, and finally tended to be stable. According to the research results, some engineering recommendations were put forward for the grouting treatment of the conduit-type water inflow disaster, which has been successfully applied in the treatment project of the China Resources Cement (Pingnan) Limestone Mine. This study provided some guidance and reference for the parameter optimization of grouting for the treatment projects of water inflow in karst conduits.
