In this paper, we made a simple paper feeding system which is one of MTS (media transport system) and controllers. The plant has a flexible paper and two driving rollers and two driven rollers. The control system has two conventional PID controllers. Skew angle and feeding speed of MTS deteriorate the quality of feeding system. In order to control a feeding speed and skew of feeding paper, we control rotational velocity of two driving rollers. Therefore, this controller has two inputs and two outputs as MIMO (multi-input and multi-output) system. The control inputs were the feeding speed and the skew displacement of the paper. The control outputs were the rotational velocity to each driving roller. To find appropriate PID gains of two controllers, we proposed an optimization technique. We assume the system variables and performance of a whole system as follows. PID gains of two controllers for skew and feeding speed are system variables. System performance is both skew and feeding speed. We simulates to making mathematical correlation using global Kriging interpolation. To find appropriate value of system variables, optimization method is simulation in sequence as following method. First, the optimization solver simulates with DOE (design of experiment) tables to find correlation equation of both system variable and performances. Then, the solver guesses the appropriate values and simulates if the system variables are appropriate or not. If the result of validation doesn't satisfy the convergence and iteration tolerance, the solver makes a new Kriging models and iterates this sequence until satisfy the tolerances.

This study investigated the effect of a health-related lifestyle on knowledge, attitude, control belief and behavior intention toward breast-feeding of male and female university students in order to develop a breast-feeding education program for students of childbearing age. The subjects were 445 university students (125 male and 325 female) residing in eight provinces in Korea. The overall percentage of subjects intending to breast-feed their baby was 80.7% (73.6% of males and 84.2% of females). Overall, 84.2% of the subjects had high concerns about their health status. Scores reflecting a positive attitude, knowledge, and control beliefs toward breast-feeding were significantly higher (p<0.05~p<0.001) in female students, students majoring in medicine, and higher grades. The students who scored high at attitude, knowledge, and control beliefs also had a significantly higher (p<0.001) intention to breast-feed. When we investigated the sub factors of attitudes toward breast-feeding, significantly more students taking nutrient supplements scored high for physiological factors (p<0.05) and health-related factors (p<0.01). Significantly more non-smoking and non-drinking students scored high for health-related factors (p<0.001) and physiological factors (p<0.001), respectively. The intention to breast-feed was found to be significantly higher (p<0.01) in students who did not smoke, but not with other health-related lifestyles. In summary, these results indicate that the majority of university students intend to breast-feed, with students having a positive attitude, higher knowledge, and stronger control beliefs having a higher intention to breast-feed. Although a student's health-related lifestyle affects their attitudes on the physiological and health-related aspects of breast-feeding, only smoking status had an observable connection on the intention to breast-feed. Thus, when developing breast-feeding education programs for students, we recommend efforts to enhance a favorable attitude, knowledge, and control beliefs toward breast-feeding.

Purpose: The purpose of this study was to develop an antepartum-postpartum breast-feeding program titled "Breastfeeding Empowerment Program" and to measure the effects of this program on breast-feeding empowerment and the rate of exclusive breast-feeding. Methods: The study design was a nonequivalent control group design with repeated measures. Results: The scores for breast-feeding empowerment of the experimental group (EG) were higher than those of the control group (CG) at week 1, 4, 8, 12. The rates for exclusive breast-feeding of the experimental group were also higher than those of the control group: 86.4% in the EG and 40.9% in the CG at week 1; 100% vs 42.9% at week 4; 86.4% vs 38.1% at week 8; 95.5% vs 38.1% at week 12; 94.7% vs 31.6% at 6 months; 89.5% vs 26.3% at 12 months. Conclusion: The study provided evidence that raising consciousness and strengthening mother's will and skills for exclusive breast-feeding helps them to achieve successful breast-feeding by themselves. In addition mothers need to be empowered to breastfeed starting before delivery and continuing after delivery. This approach could make long-term exclusive breast-feeding successful.

Two experiments under sham feeding conditions were conducted to determine whether or not ruminal distension brought about by feed boluses entering the rumen is a factor in the marked suppression of feed intake after 40 min of feeding. In experiment 1, a comparison was made between the intraruminal insertion of a water filled balloon (RIB) treatment and normal control (non-insertion of a balloon, NIB). In experiment 2, saliva lost due to sham feeding conditions was replenished via an intraruminal infusion of iso-osmotic artificial saliva. A comparison of dry forage intake was then conducted between the intraruminal replenishment of iso-osmotic artificial saliva and insertion of a balloon (RRIAS-RIB) treatment, and the intraruminal replenishment of iso-osmotic artificial saliva and non-insertion of a balloon (RRIAS-NIB) control. In experiment 1, eating rates in the RIB treatment 30 min after the commencement of feeding tended to be lower than those in the NIB control. In comparison with the NIB control, cumulative dry forage intake in the RIB treatment was 29.7% less (p<0.05) upon conclusion of the 2 h feeding period. The secreted saliva weight in the NIB control and the RIB treatment during the 2 h feeding period was 53.2% and 60.9% total weight of the boluses, respectively. In experiment 2, eating rates in the RRIAS-RIB treatment 30 min after the commencement of feeding was significantly lower (p<0.05) than those in the RRIAS-NIB control. Cumulative dry forage intake in the RRIAS-RIB treatment was a significant 45.5% less (p<0.05) compared with that in the RRIAS-NIB control upon conclusion of the 2 h feeding period. The secreted saliva weight in the RRIAS-NIB control and the RRIAS-RIB treatment during the 2 h feeding period was 54.1% and 64.2% total weight of the boluses, respectively. The level of decrease in dry forage intake in the RRIAS-RIB treatment of experiment 2 was larger than that in the RIB treatment of experiment 1. In the present experiments, due to the sham feeding conditions, the increases in osmolality of ruminal fluid and plasma, and a decrease in ruminal fluid pH which are normally associated with feeding were not observed. The results indicate that the marked decrease in feed intake observed in the second hour of the 2 h feeding period is related to ruminal distension caused by the feed consumed and the copious amount of saliva secreted during dry forage feeding.

Experiments were performed to determine the effects of the Shiryungtang (SRT) liquid extract on the hypertension and the hyperlipidemia induced by cholesterol in Sprague-Dawley rat(SDR) and Spontaneous Hypertensive rats(SHR). The results were obtained as follows : 1. The blood pressures of Sample A, B were decreased significantly compared with control group. First day, in case of Sample B, the blood pressure depressed after 1 and 2 hour. 2. After 11days of feeding with SRT, the blood pressure was decreased significantly in the treated group as compared with the control group. 3. After 11days by fed with SRT, the cholesterol had no significant in all treated group compared with the control group. 4. After 11days by fed with SRT, the triglyceride had no significant in all treated group compared with the control group. 5. The cholesterol of hypercholesterolemic rat induced by feeding with cholesterol was decreased significantly in all treated group compared with the control group. 6. The triglyceride of hypercholesterolemic rat induced by feeding with cholesterol was decreased significantly in all treated group compared with the control group. 7. The HDL-cholesterol of hypercholesterolemic rat induced by feeding with cholesterol was decreased significantly in all treated group compared with the control group. 8. The phospholipid of hypercholesterolemic rat induced by feeding with cholesterol was decreased significantly in Sample B of the treated group. 9. The total lipid of hypercholesterolemic rat induced by feeding with cholesterol was decreased significantly in Sample B of the treated group. 10. The total protein of hypercholesterolemic rat induced by feeding with cholesterol was decreased significantly in Sample B of the treated group. 11. The albumin of hypercholesterolemic rat induced by feeding with cholesterol was decreased significantly in all treated group compared with the control group. With the above result, it is thought that Shiryungtang can be applied effectively to the hypertension and hyperlipidemia.

It is difficult to determine the feeding rate of coagulant in the water treatment plant, due to nonlinearity, multivariables and slow response characteristics etc. To deal with this difficulty, the genetic-fuzzy system genetic-equation system and the neural network system were used in determining the feeding rate of the coagulant. Fuzzy system and neural network system are excellently robust in multivariables and nonlinear problems. but fuzzy system is difficult to construct the fuzzy parameter such as the rule table and the membership function. Therefore we made the genetic-fuzzy system by the fusion of genetic algorithms and fuzzy system, and also made the feeding rate equation by genetic algorithms. To train fuzzy system, equation parameter and neural network system, the actual operation data of the water treatment plant was used. We determined optimized feeding rates of coagulant by the fuzzy system, the equation and the neural network and also compared them with the feeding rates of the actual operation data.

Purpose: We developed and tested the effects of a coping skill training program for caregivers in feeding difficulty among older adults with dementia in long-term care facilities. Methods: A non-equivalent control group pretest-posttest design was used. The subjects comprised 34 caregivers (experimental group: 17, control group: 17) and 40 older adults with dementia (experimental group: 20, control group: 20). The developed program was delivered in 4-hour sessions over 6 weeks (including 2 weeks of lectures and lab practice on feeding difficulty coping skills, and 4 weeks of field practice). Data were collected before, immediately after, and 4 weeks after the program (January 3 to April 6, 2016). The data were analyzed using t-test and repeated measures ANOVA using SPSS/WIN 20.0. Results: Compared to their counterparts in the control group, caregivers in the experimental group showed a significantly greater improvement in feeding knowledge and feeding behavior, while older adults with dementia showed greater improvements in feeding difficulty and Body Mass Index. Conclusion: The study findings indicate that this coping skill training program for caregivers in feeding difficulty is an effective intervention for older adults with dementia in long-term care facilities.

Purpose: This study was designed to evaluate the effects of an individual breast-feeding promotion program to address breast-feeding knowledge, attitude, method and rate of practice for married immigrant women. Methods: A non-equivalent control group quasi-experimental design was used (experimental group=16, control group=17). The intervention consisted of 3 phases: (1) Within 2 hours of delivery - individual breast-feeding training through video/verbal/practical training education and demonstration (2) After 1~2 days - group training using video, model doll, and breast models (3) After 7 days - family visit, counseling, retraining and reinforcement training. The data were analyzed using non-parametric tests with the SPSS program. Results: Married immigrant women who participated in the individual breast-feeding program scored high in knowledge, attitude, method and rate of practice compared to the control group. Conclusion: The results indicate that the individual breast-feeding program is very effective in increasing breast-feeding knowledge, attitude, method and rate of practicing breast feeding for married immigrant women. So, nurses are encouraged to aggressively utilize individual breast-feeding programs to help married immigrant women, who are exposed to vulnerability due to various situations.

The effects of green tea (Camellia sinensis) waste silage and supplemental polyethylene glycol (PEG) on rumen fermentation and blood components were studied in cattle. Six Holstein steers were fed three diets in a 3${\times}$3 Latin square design, replicated twice. One diet was a control with no added silage, and the other two diets were supplemented (20% of the dry matter) with green tea waste silage either with (PEG) or without PEG (tea). Most of the fermentation parameters including major volatile fatty acids (VFA) were not affected by the diet treatments. The concentrations of high density lipoprotein cholesterol in the PEG group and urea nitrogen in the tea and PEG groups were greater than those in the control before morning feeding. The plasma 6-hydroxy-2,5,7,8-tetramethylchroman-2-carboxylic acid equivalent concentration was not different before morning feeding, but 3 h after morning feeding, its concentrations in both the tea and PEG groups were higher than in the control. Although the concentration of plasma vitamin A in the animals was not affected by feeding green tea waste silage, the concentrations of plasma vitamin E were significantly higher in the tea and PEG groups than in the control, both before and 3 h after morning feeding. The results from the present study suggest that feeding diets containing 20% of the dietary dry matter as green tea waste silage to Holstein steers has no negative impact on their ruminal fermentation, and increases their plasma antioxidative activity and concentration of vitamin E.

The purpose of this study was to investigate the effects of breast-feeding education program on the promotion of mothers's feeding compliance during the 4 months after childbirth. A nonequivalent control group posttest design was used. Eighty-nine pregnant women at their 32 more weeks of gestation receiving antenatal care at the Chonnam University Hospital Obstetrics Clinic were assigned to the experimental group. Control group was ninety-nine pregnant women over 32wks of gestation receiving antenatal care at the Kwangju Christianity Hospital Obstetric Clinic during the same period. Breast-feeding education program was introduced to the experimental group from antepartal visit to 4 months after childbirth. Data were collected primarily via telephone interview on the 7th day, the end of 1 month and the 4 months after childbirth respectively. The results showed that 1) the frequency of breast-feeding continuation promoting behaviors was higher in the experimental group than in the control group. 2) The rates of mothers' compliance during the 4 months after childbirth in the experimental group demonstrated a significant difference ; much higher rate of mothers' compliance than control group. Conclusively, the breast-feeding education program increase the rate of mothers' compliance and duration of breast-feeding.
