Covariance components and genetic parameters of weekly live body weight from hatching to six weeks of age and age of sexual maturation were estimated in a laying type Japanese quail line. The univariate and bivariate animal model analysis included hatching group and sex as fixed effects. Each trait was analysed with animal as random effect to fit the additive direct effect. Additional random effects incorporated in the models were changed according to the trait examined. The best model for a trait was chosen based on a likelihood ratio test, comparing the models with and without maternal additive genetic and maternal permanent environmental effects. Heritability estimates of live-weight at hatch and one to six weeks of age with their standard errors were 0.22${\pm}$0.088, 0.39${\pm}$0.099, 0.31${\pm}$0.086, 0.38${\pm}$0.056, 0.46${\pm}$0.055, 0.50${\pm}$0.059, and 0.56${\pm}$0.062, respectively. Direct heritability value of age of sexual maturation was moderate (0.24${\pm}$0.055). The variances due to permanent environmental effect of dam after one week of age and maternal genetic effect after two weeks of age were not important sources of variation. The correlations between direct and maternal genetic effects were negative and ranged from high to moderate values (-0.21 to -0.83). Among the weekly live weights, genetic correlations were generally high between not only successive but also early and late weightings. It suggests that selection for final weight may be based on early weight records. Genetic correlations between age of sexual maturation and live weights were low, favourable but had high standard errors. These results indicate that selection for high weight will potentially result in lower age of sexual maturation only with accurate determination of breeding values.

Background: Concurrent chemoradiation with three weekly high dose cisplatin is the non-surgical standard of care for the treatment of locally advanced head and neck cancers. Although this treatment regime is efficacious, it has high acute toxicity, which leads not only to increased treatment cost, but also to increased overall treatment time. Hence, the current study was undertaken to evaluate the acute toxicity and tumor response in head and neck cancer patients treated with concurrent chemoradiation using $40mg/m^2$ weekly cisplatin, which has been our institutional practice. Materials and Methods: This single institution retrospective study included data for 287 head and neck cancer patients treated with concurrent chemoradiation from 2012 to 2014. Results: The mean age of the patients was 48.8 years. The most common site of involvement was oral cavity. Most of the study patients presented with advanced stage disease. The mean overall treatment time was 56.9 days. Some 67.2% had overall complete response to treatment as documented till 90 days from the start of treatment. According to the Radiation Therapy Oncology Group (RTOG) acute radiation morbidity scoring criteria, mucositis was seen in 95.1% of the patients. Dermatitis and emesis were observed in 81.9% and 98.6%, respectively. Regarding haematological toxicity, 48.8% and 29.6% suffered from anaemia and leukopenia, respectively, during treatment. Acute kidney injury was assessed using the Common Terminology Criteria for Adverse Events (CTCAE), and was found in 18.8% of the patients. Conclusions: Concurrent chemoradiotherapy with weekly cisplatin is an effective treatment regime for head and neck cancers with reasonable toxicity which can be used in developing countries, where cost of treatment is so important.

Purpose: Histidine-containing dipeptides, which are rich in chicken, have been reported to reduce the risk of metabolic abnormalities via anticarbonylation mechanism in animal models. To determine the effect of dietary histidine-containing dipeptides on metabolic risk factors in humans, the relation between chicken consumption and insulin resistance were determined in a population consuming high carbohydrate and low protein. Methods: A total of 7,183 subjects (2,929 men and 4,254 women) aged ≥ 50 years from the Korea National Health and Nutrition Examination Survey (KNHANES) were divided into three groups according to chicken consumption (rarely, monthly, and weekly), and evaluated for the metabolic risk factors using homeostasis model assessment for insulin resistance (HOMA-IR) and quantitative insulin sensitivity check index (QUICKI) in this cross-sectional study. The fourth and fifth (IV-1-3 & V-1) KNHANES, which had blood insulin data, were chosen for the current study. Results: The chicken consumption was significantly associated with insulin (p for trend = 0.018) and HOMA-IR (p for trend = 0.023) in men. In particular, the 'weekly' chicken consuming men in the lowest tertile (< 65.0%) of carbohydrate intake group had significantly lower HOMA-IR (p for trend = 0.033) and higher QUICKI (p for trend = 0.043) than the 'rarely' intake group. In addition, the odds ratio for abnormal HOMA-IR was 0.55 (95% confidence interval [CI], 0.31-0.99) and QUICKI was 0.47 (95% CI, 0.26-0.86) for the 'weekly' chicken consuming group. Conclusion: The 'weekly' chicken consumption had a beneficial effect on insulin resistance and it may partially be due to the major bioactive components in chicken, histidine-containing dipeptides.

Tooth mobility is an important part of a periodontal examination and represents a function of the persisting height of the alveolar bone and the width of the periodontal ligament. The purpose of this study was to evaluate the changes of the tooth mobility over 4 week-period following surgical therapy on the periodontal disease. Thirty five patients presenting with moderate periodontal pockets were selected and tooth mobility was measured at weekly intervals using Periotest (Siemens Co., Germany) beginning at the pre-operation examination and ending four weeks following the modified Widman Flap. All data were statistically analyzed using the one-way ANOVA test. The results were obtained as follows; 1. All teeth exhibited the greatest change in mobility at 1 week post-op, mobility generally decreasing with time. 2. Comparison of the weekly tooth mobility data regarding the 1st premolars showed significant differences only between weeks 1 (9.94) and 4 (6.14) (p<0.05). 3. Comparison of the weekly tooth mobility data regarding the 1st molar showed significant changes in the intervals between pre-op (6.49) and week 1 (11.22), pre-op and week 2 (9.37), weeks 1 and 3 (7.65), weeks 1 and 4 (5.62), and weeks 2 and 4 (p<0.05). 4. Comparison of the weekly tooth mobility data regarding the 2nd premolar and 2nd molar showed significant differences between pre-op (6.91, 8.60) and week 1 (11.02, 12.62), weeks 1 and 3 (8.00, 8.05), weeks 3 ad 4 (6.22, 6.71), and weeks 2 (9.34, 11.01) and 4 (p<0.05).

이 연구는 노동시간이 노동자의 삶 만족도에 미치는 영향을 실증적으로 규명함으로써, 한국 장시간 노동체제가 가지는 의미의 일단을 규명하고자 한 것이다. 이 연구의 분석자료는 통계청의 2014년 생활시간조사자료이며, 노동시간 요인은 '하루 노동시간 길이'와 '주당 휴일 수준' 두가지이다. 먼저 노동시간이 삶 만족도에 미치는 영향을 검증하고, 이어서 돌봄을 필요로 하는 가족원이 있는지 여부에 따라 노동시간이 삶 만족도에 미치는 영향이 달라지는지 여부를 살펴보았다. 분석 결과, 통상 행복 수준에 영향을 미치는 소득, 교육, 고용형태, 성별 등의 요인들을 통제하는 경우에도 노동시간 길이가 길수록, 휴가 수준이 낮을수록 한국인의 삶 만족도는 저하된다. 그러나 돌봄을 요하는 가족원이 있는 경우 노동시간이 삶 만족도에 미치는 영향은 달라진다. 돌봄을 필요로 하는 가족원이 있는 경우, 노동시간 길이와 휴가 수준은 삶 만족도에 더 이상 유의미한 영향을 미치지 않으며, 성별이 삶 만족도에 미치는 영향력의 유의미성 역시 사라진다. 이는 돌봄을 요하는 가족원이 없는 경우에, 노동시간이 미치는 영향 및 여성이 남성보다 삶 만족도가 높은 것과 대조된다. 이는 한국 가족의 돌봄시간 성별 격차와 깊이 관련되어 있는 것으로 추정된다.
