In this paper, we compute the trace field of C(2, s), the complement of two component chain link with s left half twists in ${\mathbb{S}}^3$, for every s. As a result, for every $n{\in}{\mathbb{N}}{\backslash}\{1\}$, we can find $s{\in}{\mathbb{Z}}$ such that the degree of the trace field of C(2, s) is n. We also prove that if for fixed p, the degree of the trace field of C(p, s) runs over ${\mathbb{N}}{\backslash}\{1\}$, then p is contained in {1, 2, 4, 8}.

Objective: Two trials were conducted in order to examine the effects of level of supplemental methionine on productive performance, dietary energetic, plasma amino acid concentration, and digestive function. Methods: Dietary treatments consisted of a steam-flaked corn-based diet containing urea as the only source of supplemental nitrogen supplemented with no supplemental amino acid (control), or control plus 1.01% lysine and 0.032%, 0.064%, 0.096%, or 0.128% methionine. In Trial 1, 150 Holstein steer calves ($127{\pm}4.9kg$) were utilized to evaluate the influence of treatments on growth-performance, dietary energetic, plasma amino acid concentration during the first 112 days of growing period. During the initial 56-d period calves received the 5 experimental diets. During the subsequent 56-d period all calves were fed the control diet. Results: During the initial 56-d period, methionine supplementation increased (linear effect, p<0.01) plasma methionine. In the presence of supplemental lysine, increases on level of methionine in diet did not affect average daily gain. However, increased gain efficiency (quadratic effect, p = 0.03) and estimated dietary net energy (NE; linear effect, p = 0.05). Estimated metabolizable methionine supply was closely associated ($R^2=0.95$) with efficiency NE utilization for maintenance and gain. During the subsequent 56-d period, when all calves received the control diet (no amino acid supplementation), plasma amino acid concentrations and growth performance was not different among groups. However, the effects of methionine supplementation during the initial 56-period carried over, so that following a 56-d withdrawal of supplementation, the overall 112-d effects on gain efficiency (quadratic effect, p = 0.05) dietary NE (linear effect, $p{\leq}0.05$) remained appreciable. In Trial 2, 5 cannulated Holstein steers were used to evaluate treatment effects on characteristics of digestion and amino acid supply to the small intestine. There were no treatment effects on flow of dietary and microbial N to the small intestine. Postruminal N digestion increased (p = 0.04) with increasing level of supplemental methionine. Methionine supplementation linearly increased (p<0.01) duodenal flow of methionine. Likewise, lysine supplementation increased an average of 4.6% (p = 0.04) duodenal flow of lysine. In steers that received non-supplemented diet, observed intestinal amino acid supply were in good agreement with expected. Conclusion: We conclude that addition of rumen-protected methionine and lysine to diets may enhance gain efficiency and dietary energetics of growing Holstein calves. Observed amino acid supply to the small intestine were in good agreement with expected, supportive of NRC (2000, Level 1).

Objectives: The purpose of this study was to compare the decidual NK cell populations between increased pre-conceptional peripheral NK cell population and normal pre-conceptional peripheral NK cell population in women with a history of recurrent abortion. Methods: Fourteen women with history of recurrent abortion and elevated pre-conceptional peripheral NK cell, above 15% of peripheral lymphocyte population were included in this study. As a control, twelve women with history of recurrent abortion and their peripheral NK cell percentage showed below 15% were included. Distribution of $CD56^+$ and $CD16^+$ NK cells in paraffin embedded decidual tissues including implantation sites were examined by immunohistochemical staining using anti-CD56, 16 monoclonal antibodies. After immuohistochemical staining, the numbers of decidual NK cells were counted and compared these results between study and control groups. Results: There was significant difference in decidual $CD56^+$ NK cell count ($170.1{\pm}132.1$ vs. $68.3{\pm}66.1$, p=0.02) between increased peripheral $CD56^+$ NK cell group and control group. But, there showed no statistically significant correlation between decidual $CD56^+$ NK cell count and peripheral $CD56^+$ NK cell percentage (r=0.229, p=0.261). Also there was no statistically difference decidual $CD16^+$ NK cell count between study and control group ($25.70{\pm}11.72$ vs. $31.17{\pm}22.67$), and no correlation between decidual $CD16^+$ NK cell and peripheral $CD16^+$ NK cell percentage (r=-1.40, p=0.535). Conclusions: This study shows that decidual $CD56^+$ NK cell are significantly increased in decidua of women exhibiting a history of recurrent abortion with increased $CD56^+$ peripheral NK cell. This study suggests that the percentage of peripheral NK cell reflect the expression of decidual NK cell. Consequently, pre-conceptional peripheral blood NK cell population can be the useful marker for detecting the risk of subsequent miscarriage.

This study is a descriptive survey research on nursing workers at long-term care hospitals, who are largely divided into nurses and nurse aides, to identify the factors that affect their turnover intention. From August 12 to 16, 2022, the survey was conducted for 146 nursing workers in four long-term care hospitals located in G city. The survey results indicated that there were differences in their turnover intention depending on their age, religion, marital status, educational level, average monthly salary, job type, duty pattern and turnover experience, of all general characteristics (p<.05). Turnover intention had a significant positive correlation with job stress (r=.51, p<.001) and burnout (r=.62, p<.001), and had a significant negative correlation with organizational commitment (r=.-56, p<.001). Organizational commitment had a significant negative correlation with job stress (r=-.25, p=.002) and burnout (r=.-.67, p<.001), while burnout had a significant positive correlation with job stress (r=.56, p<.001). Factors influencing the nursing workers' turnover intention included job stress (β=.32, p<.001), organizational commitment (β=-.30, p=.001) and education level (β=.17, p=.022), with an explanatory power of 49.6%. Based on the results of this study, it is considered that efforts to improve the working environment for nursing workers at long-term care hospitals are needed by reducing their job stress and improving organizational commitment in order to reduce their turnover intention.

In order to remove the pollutants effectively in the dye wastewater by chemical precipitation process, coagulation arid flocculation test were carried out using several coagulants on various reaction conditions. It was found that the Ferrous sulfate was the most effective coagulant for the removal of disperse dye(B79), and we could get the best result lot the removal of disperse dye(B56) in the aspects of TOC removal efficiency and sludge field. When the Ferrous sulfate dosage was $800mg/\ell$, the sludge settling velocity was very fast>, and the color was effectively removed in the disperse dye(B79) solution. Although the color removal was ineffective when the Alum was used as a coagulant, the sludge field was decreased in comparison with the Ferrous sulfate or the Ferric sulfate was used in the disperse dye(B56) solution. The general color removal effect for the disperse dye(B56 and B79) solutions, the Ferric sulfate was more proper coagulant than the Alum. It was showed that TOC removal was improved 5% and over by the addition of Calcium hydroxide, and $30mg/\ell$ of sludge yield was decreased(B79). When Alum or Ferric sulfate was used as a coagulant, pH condition for most effective color removal was 5 in B56 solution. In case of Ferrous sulfate as a coagulant, most effective pH condition for color removal was 9. When Ferric sulfate or Ferrous sulfate was used as a coagulant, pH condition for most effective color removal was 9 in B79 solution.

This study was conducted to investigate the efficacy of surface spraying of antimicrobial solutions, oil and application of both on performance of broiler chicken under heat stress and reared on leaves and ground corn cobs as two alternative bedding materials. Six hundred seventy five day-old straightrun Arian broiler chicks were randomly assigned to 45 pens (at density of $0.09m^2/bird$) in an open sided partially-controlled shed. Three bedding materials viz. wood shavings (WS), ground corn cobs (GCC) (1.5 cm in length) and leaves were subjected to surface spraying of oil ($0.4L/m^2$ animal food grade sunflower oil), anti microbial solutions (3%) and mix treatment of both. Data on performance traits, incidence of breast and food pad lesions and litter characteristics were gathered and analysed in an appropriate factorial arrangements. Body weight at 56 d, feed intake up to 14 d, litter moisture at 28 d, litter pH at 14 d and litter temperature at 14 and 56 d were significantly influenced by litter type (p<0.05). Litter treatment revealed significant impact on body weight at 28, 42 and 56 d, feed intake during 29-42 and 1-42 d, mortality up to 56 d, litter temperature at 28 and 56 d, and litter pH at 28 and 56 d. Leaves and ground corn cobs have shown good potential as alternative bedding materials for rearing broilers. Surface spraying of antimicrobial solutions, oil and applying both were not effective tools to promote the broiler's health and performance. Meat type poultry growers and integrators are considered as primary audiences of the results achieved.
