  • The objective of this study was to estimate genetic parameters for test-day milk production and somatic cell score using field data collected by dairy herd improvement program in Korea. Random regression animal models were applied to estimate genetic variances for milk production and somatic cell score. Heritabilities for milk yields, fat percentage, protein percentage, solid-not-fat percentage, and somatic cell score from test day records of 5,796 first lactation Holstein cows were estimated by REML algorithm in single trait random regression test-day animal models. For these analyses, Legendre polynomial covariate function was applied to model the fixed effect of age-season, the additive genetic effect and the permanent environment effect as random. Homogeneous residual variance was assumed to be equal throughout lactation. Heritabilities as a function of time were calculated from the estimated curve parameters from univariate analyses. Heritability estimates for milk yields were in range of 0.13 to 0.29 throughout first lactation. Heritability estimates for fat percentage, protein percentage and solid-not-fat percentage were within 0.09 to 0.11, 0.12 to 0.19 and 0.17 to 0.23, respectively. For somatic cell score, heritabilities were within 0.02 to 0.04. Heritabilities for milk productions and somatic cell score were fluctuated by days in milk with comparing 305d milk production.

  • The objective of this study was to estimate genetic parameters that are to be used for across-herd genetic evaluations of seed stock pigs at GGP level. Performance data with pedigree information collected from swine breeder farms in Korea were provided by Korea Animal Improvement Association (AIAK). Performance data were composed of final body weights at test days and ultrasound measures of back fat thickness (BF), rib eye area (EMA) and retail cut percentage (RCP). Breeds of swine tested were Landrace, Yorkshire and Duroc. Days to 90 kg body weight (DAYS90) were estimated with linear function of age and ADG calculated from body weights at test days. Ultrasound measures were taken with A-mode ultrasound scanners by trained technicians. Number of performance records after censoring outliers and keeping records pigs only born from year 2000 were of 78,068 Duroc pigs, 101,821 Landrace pigs and 281,421 Yorkshire pigs. Models included contemporary groups defined by the same herd and the same seasons of births of the same year, which was regarded as fixed along with the effect of sex for all traits and body weight at test day as a linear covariate for ultrasound measures. REML estimation was processed with REMLF90 program. Heritability estimates were 0.40, 0.32, 0.21 0.39 for DAYS90, ADG, BF, EMA, RCP, respectively for Duroc population. Respective heritability estimates for Landrace population were 0.43, 0.41, 0.22, and 0.43 and for Yorkshire population were 0.36, 0.38, 0.22, and 0.42. Genetic correlation coefficients of DAYS90 with BF, EMA, or RCP were estimated to be 0.00 to 0.09, -0.15 to -0.25, 0.22 to 0.28, respectively for three breeds populations. Genetic correlation coefficients estimated between BF and EMA was -0.33 to -0.39. Genetic correlation coefficient estimated between BF and RCP was high and negative (-0.78 to -0.85) but the environmental correlation coefficients between these two traits was medium and negative (near -0.35), which describes a highly correlated genetic response to selection on one or the other of these traits. Genetic Trends of all three breeds tend to be towards bigger EMA or greater RCP and shorter DAYS90 especially from generations born after year 2000.

  • Purpose: The purpose of this study was to investigate the sleep/activity patterns of premature babies. Method: The subjects were 55 premature babies who were hospitalized in the Neonatal Intensive Care Unit (NICU) of one University Hospital in Daejeon from September 1, 2004 to March 31, 2006. The sleep/activity patterns of the premature babies were observed for 24 hours a day for 7 days. The observations were made and recorded by the researcher and 5 trained research assistants using NCASA records developed by Barnard et al. (1979). For statistical analysis, frequency, average, t-test, and Pearson correlation coefficients were used. Results: The infants slept more and had less awake periods during daytime than full-term infants. As the hospital stay of the premature babies increased, the amount of daytime sleep and total daily sleep decreased, and the amount of daytime awake periods increased. Conclusions: The findings suggest that the level of physical and physiological maturity of premature babies is one of the major variables that affect their sleep/activity patterns. Furthermore, the findings of this study will provide information about the sleep/activity patterns of premature babies, and present baseline data to develop the nursing intervention programs which support optimum development for the premature babies.

  • It is well recognized that case management is required to survive in the rapidly changing medical environment. One of the case management is the critical pathway(CP) which is assumed to increase the quality of care and at the same time to decrease the length of stay in hospital. The purpose of the study was to develop a CP for the management of patients with postero-lateral fusion for lumbar spinal stenosis. Through review of literature and medical records of patients with spinal stenosis, a pilot CP was designed, including 8 different care components such as medication, laboratory tests, assessment etc., from one day before surgery to 6 days of postoperative care. Every item of the pilot CP was evaluated by a panel of experts to test the content validity. The items not agreed on by more than 4 out of 6 experts were deleted or modified to be integrated in the CP. To apply the modified CP to a clinical environment, the items reflecting treatment, medication and lab work were entered into an order communication system(OCS), and doctors and nurses were taught to use the CP. Finally, the development of CP for the patients with posterolateral lumbar fusion was completed after the application and variance analysis of the CP.

  • The purpose of this study was to examine the actual condition on consumption of adolescents, focused on their pocket money. Three-hundred students attending in middle and high school in Kyounggi Province were selected, and surveyed using questionnaires. Out of them, 272 students were used in statistical analysis, with frequency, percentage and Chi-test in SPSS/PC+ program. The results were as follows : First, most adolescents got pocket money irregularly from their mothers and average amount per month was more than 10 thousands and less than 50 thousands won. And they weren't satisfied with that amount, especially girl students. Second, most adolescents got extra money when it is a gala day or their records were improved. And most of them did nothing on consideration for their pocket money. Third, most adolescents spent pocket money for hobby or leisure and for snacks. Fourth, most adolescents had never guided how to spend money and had never evaluated their money spending. Fifth, most adolescents tried to spend money thoughtfully and evaluated their friends spent money on impulse. Sixth, most adolescents wanted to buy clothings and friends influenced their spending habit.

  • Objectives Despite the treatment with antibiotics, patients with sepsis has a high mortality (80%) in the underlying disease group. The aim of this study was to report the improvement of septic condition of the cholangiocarcinoma patient after the treatment with Handayeolso-tang, Fel Tauri, and antibiotics. Methods We retrospectively reviewed the medical records. The patient's subjective symptoms such as chilling and abdominal pain were evaluated by NRS and the performance status was evaluated by ECOG. This case was literally compared with relevant published studies on prognosis of sepsis. Results Despite poor prognostic factor(MEDS score 18), the patient's symptoms such as fever, chilling, abdominal pain, and diarrhea and ECOG(Eastern Cooperative Oncology Group) improved. The patient was hemodynamically stabilized on 3rd day from the treatment, and her laboratory test results were normalized on 7th day. Conclusions A female patient of metastatic cholangiocarcinoma came to the hospital for cholangitis, later causing septic shock. Both her symptoms and laboratory tests showed significant improvement after the treatment of antibiotics, Handayeolso-tang and Fel Tauri. To our knowledge, this is the first case reporting the synergistic combination of Korean oriental medicine and Western medicine approaching to sepsis.

  • A total of 32,817 test-day milk yield (TDMY) records of the first lactation of 4,056 Girolando cows daughters of 276 sires, collected from 118 herds between 2000 and 2011 were utilized to estimate the genetic parameters for TDMY via random regression models (RRM) using Legendre's polynomial functions whose orders varied from 3 to 5. In addition, nine measures of persistency in milk yield ($PS_i$) and the genetic trend of 305-day milk yield (305MY) were evaluated. The fit quality criteria used indicated RRM employing the Legendre's polynomial of orders 3 and 5 for fitting the genetic additive and permanent environment effects, respectively, as the best model. The heritability and genetic correlation for TDMY throughout the lactation, obtained with the best model, varied from 0.18 to 0.23 and from -0.03 to 1.00, respectively. The heritability and genetic correlation for persistency and 305MY varied from 0.10 to 0.33 and from -0.98 to 1.00, respectively. The use of $PS_7$ would be the most suitable option for the evaluation of Girolando cattle. The estimated breeding values for 305MY of sires and cows showed significant and positive genetic trends. Thus, the use of selection indices would be indicated in the genetic evaluation of Girolando cattle for both traits.

  • Objectives : This study was conducted to investigate the frequent diseases among the people who had been treated by collaborative treatment of Korean medicine and Western medicine, and to compare their medical use behaviors before and after the collaborative first-stage pilot project between Korean medicine and Western medicine. Methods : 4,467 patients were identified as the patients who are participated in the collaborative first-stage pilot project between Korean medicine and Western medicine during the period between July 15, 2016 and March 31 2017. We used 28,480 records of Korean national health insurance claim data from January 1 2016 to March 31 2017 to analyzed present condition of cooperative medical usage. Also we conducted a paired t test to compare the percentage of collaborative treatment days before and after the pilot project period. Results : We found that the most frequent diseases treated in the pilot project were the diseases of musculoskeletal and nervous system and then 10 major diseases such as H, K, J, C (D), N, L, E, A, H and F disease codes in order. Also it was confirmed that 14 major and 53 medium diseases are included from more than 90% of total patients. As a result of high frequency of medical treatment in Western medicine or Korean medicine is "administration of Korean medicine", which is same as before and within the pilot project. The ratio of utilizing both Western and Korean medical care for the same disease on the same day by both general patients and patients in KCD-7 disease code group C, G, I, M and S had been increased significantly. Conclusions : The pilot project might change the behavior of utilizing the medical care service by increasing the ratio of collaborative treatment of Western medicine and Korean medicine for the same disease on the same day.

  • Objective: Considering the importance of dairy farming and the negative effects of heat stress, more tolerant genotypes need to be identified. The objective of this study was to investigate the effect of heat stress via temperature-humidity index (THI) and diurnal temperature variation (DTV) in the genetic evaluations for daily milk yield of Holstein dairy cattle, using random regression models. Methods: The data comprised 94,549 test-day records of 11,294 first parity Holstein cows from Brazil, collected from 1997 to 2013, and bioclimatic data (THI and DTV) from 18 weather stations. Least square linear regression models were used to determine the THI and DTV thresholds for milk yield losses caused by heat stress. In addition to the standard model (SM, without bioclimatic variables), THI and DTV were combined in various ways and tested for different days, totaling 41 models. Results: The THI and DTV thresholds for milk yield losses was THI = 74 (-0.106 kg/d/THI) and DTV = 13 (-0.045 kg/d/DTV). The model that included THI and DTV as fixed effects, considering the two-day average, presented better fit (-2logL, Akaike information criterion, and Bayesian information criterion). The estimated breeding values (EBVs) and the reliabilities of the EBVs improved when using this model. Conclusion: Sires are re-ranking when heat stress indicators are included in the model. Genetic evaluation using the mean of two days of THI and DTV as fixed effect, improved EBVs and EBVs reliability.
