Objective: The objective of this study was to estimate genetic parameters of milk, fat, and protein yields within and across lactations in Tunisian Holsteins using a random regression test-day (TD) model. Methods: A random regression multiple trait multiple lactation TD model was used to estimate genetic parameters in the Tunisian dairy cattle population. Data were TD yields of milk, fat, and protein from the first three lactations. Random regressions were modeled with third-order Legendre polynomials for the additive genetic, and permanent environment effects. Heritabilities, and genetic correlations were estimated by Bayesian techniques using the Gibbs sampler. Results: All variance components tended to be high in the beginning and the end of lactations. Additive genetic variances for milk, fat, and protein yields were the lowest and were the least variable compared to permanent variances. Heritability values tended to increase with parity. Estimates of heritabilities for 305-d yield-traits were low to moderate, 0.14 to 0.2, 0.12 to 0.17, and 0.13 to 0.18 for milk, fat, and protein yields, respectively. Within-parity, genetic correlations among traits were up to 0.74. Genetic correlations among lactations for the yield traits were relatively high and ranged from $0.78{\pm}0.01$ to $0.82{\pm}0.03$, between the first and second parities, from $0.73{\pm}0.03$ to $0.8{\pm}0.04$ between the first and third parities, and from $0.82{\pm}0.02$ to $0.84{\pm}0.04$ between the second and third parities. Conclusion: These results are comparable to previously reported estimates on the same population, indicating that the adoption of a random regression TD model as the official genetic evaluation for production traits in Tunisia, as developed by most Interbull countries, is possible in the Tunisian Holsteins.

Purpose: The aim of this study was to investigate the influencing effects of type D personality on symptom experiences and quality of life in percutaneous coronary intervention patients. Methods: A descriptive, cross-sectional study design was used. A total of 158 patients with percutaneous coronary intervention participated in this study, between July 1 and November 1, 2015. Data were analyzed by means, standard deviations, t-test, $x^2$ test, ANCOVA, and stepwise multiple regression analysis using SPSS 22.0 program. Results: About 53.8% of participants were classified as type D personality. The type D personality group reported statistically significantly higher symptom experience, lower cardiac function, and lower cardiovascular-specific quality of life compared to non-type D personality group. On stepwise multiple regression, the most significant factor of quality of life was symptom experiences (adjusted $R^2=.25$, p<.001), followed by type D personality (adjusted $R^2=.31$, p<.001). Conclusion: Personality trait assessment is recommended for patients with percutaneous coronary intervention to assess symptom experiences and quality of life. In addition, development of nursing intervention might be beneficial to manage symptom experience and quality of life in percutaneous coronary intervention patients with type D personality.

Objective: Because lactation periods in dairy cows lengthen with increasing total milk production, it is important to predict individual productivities after 305 days in milk (DIM) to determine the optimal lactation period. We therefore examined whether the random regression (RR) coefficient from 306 to 450 DIM (M2) can be predicted from those during the first 305 DIM (M1) by using a RR model. Methods: We analyzed test-day milk records from 85,690 Holstein cows in their first lactations and 131,727 cows in their later (second to fifth) lactations. Data in M1 and M2 were analyzed separately by using different single-trait RR animal models. We then performed a multiple regression analysis of the RR coefficients of M2 on those of M1 during the first and later lactations. Results: The first-order Legendre polynomials were practical covariates of RR for the milk yields of M2. All RR coefficients for the additive genetic (AG) effect and the intercept for the permanent environmental (PE) effect of M2 had moderate to strong correlations with the intercept for the AG effect of M1. The coefficients of determination for multiple regression of the combined intercepts for the AG and PE effects of M2 on the coefficients for the AG effect of M1 were moderate to high. The daily milk yields of M2 predicted by using the RR coefficients for the AG effect of M1 were highly correlated with those obtained by using the coefficients of M2. Conclusion: Milk production after 305 DIM can be predicted by using the RR coefficient estimates of the AG effect during the first 305 DIM.

Objective : This study investigated the relationship between the resilience and posttraumatic stress symptoms, as well as comorbid symptoms in firefighters. Methods : We collected 764 firefighters, who worked at six fire department stations in Gangwon-do. We investigated the impact of event scale-revised (IES-R), the life events checklists (LEC), Connor-Davidson resilience scale (CD-RISC), Beck depression inventory (BDI), state trait anxiety inventory (STAI) and alcohol use disorder identification test (AUDIT). Full PTSD groups, partial PTSD groups and non-PTSD groups, which were classified by IES-R scores, were compared in the LEC, CD-RISC, BDI, STAI and AUDIT, ; multiple linear regression analyses were done for independent predictors of variables. Results : Of the 764 firefighters, there were significant differences in LEC (p<0.001), CD-RISC (p<0.001), BDI (p<0.001), and AUDIT (p=0.001) among the full PTSD groups, partial PTSD groups and non-PTSD groups. However, STAI did not show significant difference among three groups. In multiple regression analysis, CD-RISC (${\beta}=-0.168$, p<0.001), LEC (${\beta}=0.211$, p<0.001) and AUDIT (${\beta}=0.115$, p=0.001) were significant predictors for IES-R. Conclusion : The results of the present study suggested that resilience might be a protective factor in PTSD and comorbid symptoms of PTSD.

Basal cell nevus syndrome is a hereditary disease of an autosomal dominant trait with variable conditions such as basal cell carcinomas of the skin, deformity of rib, fusion of vertebrae, mental retardation, hypertelorism, and multiple odontogenic keratocysts. A 32 years old man with pus discharge from fistula on the vestibule of left upper 1st molar visited to Chosun University Dental Hospital. Radiographic evaluation revealed multiple maxillary and mandibular cysts that had multilocular radiolucency on left mandibular body area, thining of inferior border of left border of ramus and well defined unilocular radiolucency above right upper 1st and 2nd molar and from left upper 1st premolar to 2nd molar. In chest PA view, he had a forked rib in the left 4th rib and in skull PA view the calcification of falx cerebri was observed. There was not any skin lesion. After the preliminary evaluation, the patient was diagnosed with basal cell nevus syndrome and he underwent marsupialization for decreasing the size of cystic lesion and came to hospital for dressing 3days a week. As time goes by, the size of lesion decreased. So, one and half year after marsupialization, he underwent cyst enucleation and iliac bone graft for the mandibular lesion and buccal fat pad grafts for the maxillary lesions. After the surgery, the patient experienced normal healing without any complications and he is on long-term follow-up.

Purpose: The purpose of this study was to examine the correlations among emotional perception clarity, emotion regulation, family relationship, non-suicidal self-injury, and depression, and to determine associated factors of non-suicidal self-injury and depression for senior elementary school students. Methods: Data were collected from 150 early adolescences in K region, Korea. A self-report questionnaire consisted of Trait Meta-Mood Scale, Cognitive Emotion Regulation Questionnaire, Family Relationship Assessment Scale, Functional Assessment of Self-Mutilation, and Children's Depression Inventory. The data were analyzed using t-test, Pearson's correlation coefficient, logistic regression, and multiple regression analysis. Results: Non-suicidal self-injury and depression were positively associated with maladaptive emotion regulation strategy and family conflict, but negatively related to emotional perception clarity and family support. Adaptive emotion regulation strategy and family togetherness were only significantly correlated with depression. In logistic regression analysis, significant predictors of non-suicidal self-injury were emotional perception clarity, maladaptive emotion regulation strategy, and family support. Multiple regression analysis found that significant factors of depression were adaptive and maladaptive emotion regulation strategies, which explained 38.0% of the variance. Conclusion: Our study findings suggest that targeted intervention to reinforce the adaptive emotion regulation strategy and family relationship may prevent non-suicidal self-injury, and depression for senior elementary school students.
