Two experiments were conducted to investigate the feeding value of stevia by-product (SB) on performance in broiler chicks and laying hens. In experiment 1, a total 256 one day old male broiler chicks were replaced in 0, 2, 4, 7% of SB with four replicates for 5 weeks. All diets were consisted of isocaloric and isonitrogen containing CP 21.5, 19% and ME 3,100 kcal/kg for starting and finishing period, respectively. Weight gain of SB treatments decreased compared with control for the first three weeks, but no difference for the finishing period. Feed intake and feed conversion were no statistical difference between control and feeding stevia groups for overall period. There were no different total number of intestinal microflora. However, the number of Salmonella and E. coli of cecum seemed to decrease in SB feeding groups. Total Lactobacillus and yeast tended to be higher in those groups than control. The PUFa increased in SB treatments, but was no significance. In experiment 2. stevia by-product(SB) were mixed with iso-caloric and isonitrogeneous method to investigate the feeding value in induced molting hens of 78 weeks old. A total 360 birds were replaced in the four treatments(0, 2, 4, 8% SB) with five replicates. Egg production, quality and fatty acid composition in egg were periodically measured for 20 weeks. No difference were found in egg production, feed intake, feed conversion between control and SB treatments for overall period. Egg shell breaking strength, thickness, albumen height and Haugh unit were not statistically different. However, yolk color was significantly high in SB treatments compared to control(P<0.05). Yolk MUFA increased significantly in SB treatments compared to that of control(p<0.05), but PUFA tended to decrease in SB treatments. No significant difference was detected in total sugar in egg yolk between SB treatments and control. Tocopherol of egg yolk 2 and 4% SB were significantly higher than those feed the control (p<0.05).
Chronic pain is one of the leading causes of hospital visits. It not only affects the patients themselves but also has a major negative impact on their families and society. In this study, we investigated epidemiology of musculoskeletal disorders induced chronic pain among general population based on Korea National Health and Nutrition Examination Survey database and also analysed how it influenced on the use of medical services. This study was done by using the data of 5th Korea National Health and Nutrition Examination Survey (KNHANES V), taking aged 20 years and over adults as research subjects. The EuroQoL-5 Dimension Index(EQ-5D) was used as a survey instrument. T-test, chi-square test and multivariate logistic regression were used for statistical analysis. Subjects with chronic pain had a higher likelihood than control group to use medical services(odds ratio : 5.858, confidence interval 3.636-9.438). Controlling for existence of chronic pain, more women were likely to use medical services than men(1.156, 0.707-1.889). Age, gender and household income level did not affect the use of medical services. Proper control of chronic pain is very helpful in improving patient's quality of life and it also accounts for a large proportion in suppressing excessive consumption of medical services. Anesthesia and pain medicine specialists have superior knowledge about analgesics and anticonvulsants than other physicians do and also have specialized skills to perform procedures like nerve blocks in treating chronic pain. Therefore Anesthesia and pain medicine specialists need to play a leading role in managing chronic pain.

Purpose: The purpose of this study is to help apply spiritual care in clinics by testing whether spiritual support like prayer and praise, which is appled on a patient who has been cared for by Facility Hospice can have an effect on their physical pain, emotional anxietv, loneliness and well being. Method: This research was done on a subject patient who had been hospitalized in Saemmul from Jan, 2002 to June, 2003, and who could easily communicate. Questionnaire of quality of life, they had this test from the date of admission into the hospital 1week, 3week, 5week later. The Target was 182 people for the hospital data, 124 people after one week, 84 people after 3 weeks and 54 people after for 5 weeks later. For statistics, SPSS for Window(SPSS inc. ver.10), student T-test and one way ANOVA were used. The interrelation between pray and pain was analyzed by the "Pearson correlation". In case where the P-value was below 0.05, we concluded it had statistical-value. Results: When we compared both the party which had a low degree of peace by prayer and praise and the B party which had the highest degree, B party had an increasing tendency for less anxiety and loneliness and more well-being. Each of the data 0, 1, 3 and 5 week showed visible difference between both parties. Conclusion: First, in case that a late cancer patient is hospitalized, the difference for tranquility and pain control by prayer and praise is not noticeable. While, 1 and 3 weeks later, the difference is visible, so we concluded the relationship between the cancer patient's spiritual tranquility and physical pain are closely related with each other. Also the patients who are in spiritual peace by prayer and praise can control the pain better than the other patients. Second, because the patient who can feel calm from the data of being admitted into the hospital is mentally calm, both party's difference is noticeable in each period of the 1, 3 and 5th week. Compared with other patients, the object patients who have spiritual tranquility will have less anxiety and loneliness and more tranquility.
Background: The impairment of the appearance is a major problem for patients with carcinomas of the oral cavity. These patients want to recover their preoperative facial appearance. Some do not realize that this is not always possible and hence develop a desire for further cosmetic and reconstructive surgery (CRS) which often causes psychological problems. Method: The desire of patients for CRS (N = 410; 26%) has been acquired in this $D{\ddot{O}}SAK$ rehab study including multiple reasons such as medical, functional, aesthetic and psychosocial aspects. They relate to the parameters of diagnosis, treatment and postoperative rehabilitation. Patients without the wish for CRS (N = 1155; 74%) served as control group. For the surgeons, knowledge of the patient's views is relevant in the wish for CRS. Nevertheless, it has hardly been investigated for patients postoperatively to complete resection of oral cancer. In this retrospective cross-sectional study, questionnaires with 147 variables were completed during control appointments. Thirty-eight departments of Oral and Maxillofacial Surgery took part, and 1652 German patients at least 6 months after complete cancer resection answered the questions. Additionally, a physician's questionnaire (N = 1489) was available. Statistical analysis was performed with SPSS vers. 22. Results: The patient's assessment of their appearance and scarring are the most important criteria resulting in wishes for CRS. Furthermore, functional limitations such as eating/swallowing, pain of the facial muscles, numb regions in the operating field, dealing with the social environment, return to work, tumour size and location, removal and reconstruction are closely related. Conclusion: The wish for CRS depends on diverse functional psychosocial and psychological parameters. Hence, it has to be issued during conversation to improve rehabilitation. A decision on the medical treatment can be of greater satisfaction if the surgeon knows the patients' needs and is able to compare them with the medical capabilities. The informed consent between doctor and patient in regard to these findings is necessary.

Sales representatives of automobile company play a key role in the circulation system. Given the characteristics of the good, consumers demand high-quality information and guides from the salespersons when they decide to purchase an automobile. Sales representatives provide service to the customers in accordance with their needs to help purchase decision-making process. Therefore, a sales representative's personal competence have a significant effect on sales performance. Based on this hypothesis, we assumed that personal competence of a salesperson has a positive correlation with sales performance. An empirical analysis was conducted to test the hypothesis. This study classifies personal competence into 4 independent variables((1) sales technique professionalism (2) salesperson's attitude and relationship with customers (3) emotion utilization (4) emotion control) and measures the correlation with the dependent variable(sales performance). To verify the relationship, we set and modified the hypothesis based on the precedent studies and researches. In addiction, a survey was conducted targeting 300 local salespersons from Gyeonggi-Gangwon region. 268 valid samples were used and analyzed with SPSS WIN24.0 statistical program. As a result of an empirical analysis, it turned out that sales technique professionalism and emotion utilization have positive correlation with sales performance. However, the result failed to support the assumption that sales representative's attitude and relationship with customers and emotion control have positive correlation with sales performance. At last the result revealed that personal competence should be considered as an important determinant of recruitment specification for sales representatives.

Plants under the genus Orostachys have been known as medicinal plants. This study deems to determine the growth and leaf color of Orostachys japonica and O. boehmeri when subjected to various LED light sources. A total of seven LED light treatments were used, i.e. red (630 nm), green (520 nm), blue (450 nm), purple (650 and 450 nm), 3000 K white (455, 600 nm), 4100 K white (455, 590 nm), and 6500 K white (450, 545 nm) LEDs. Results showed that O. japonica plants showed favorable growth under 4100 K white LED, while O. boehmeri plants had a positive growth response under white light LEDs (3000, 4100, and 6500 K). In leaf color analysis, the use of green LED showed the greatest change in CIELAB L* and b* values which were relatively higher compared to other treatments indicating that leaves turned yellowish. Further statistical analysis using Pearson's correlation also suggested that there is a small negative association between dry weight and b* values of O. japonica, and a negative moderate association between plant weights (fresh and dry weight) and leaf color (L* and b*) and positive association between said plant weights and a* color values of O. boehmeri. Therefore, it is recommended to cultivate O. japonica under 4100 K white LED and O. boehmeri under 3000, 4100, 6500 K white LEDs.
The purpose of this study was intended to recognize the importance of quality control (QC) in order to reduce exposure and improve image quality by comparing the center-point (CP) of according to hospital grade and the difference between X-ray field (XF) and light field (LF) in diagnostic digital X-ray devices. XF and LF size, CP were measured in 12 digital X-ray devices at 10 hospitals located in 00 metropolitan cities. Phantom was made in different width respectively, using 0.8 mm wire after attaching to the standardized graph paper on transparent plastic plate and marked as cross wire in the center of the phantom. After placing the phantom on the table of the digital X-ray device, the images were obtained by shooting it vertically each field of survey. All images were acquired under the same conditions of exposure at distance of 100cm between the focus-detector. XF and LF size, CP error were measured using the picture archiving communication system. data were expressed as mean with standard error and then analyzed using SPSS ver. 22.0. The difference in field between the XF and LF size was the smallest in clinic, followed by university hospitals, hospitals and general hospitals. Based on the university hospitals with the least CP error, there was a statistically significant difference in CP error between university hospitals and clinics (p=0.024). Group less than 36-month after QC had fewer statistical errors than 36-month group (0.26 vs. 0.88, p=0.036). The difference between the XF and LF size was the lowest in clinic and CP error was the lowest in university hospital. Moreover, hospitals with short period of time after QC have fewer CP error and it means that introduction of timely QC according to the QC items is essential.
Effect of 6kg large unit with the carton box (20% open ratio) and MA box (10,000cc·m-2·day-1·atm-1 oxygen transmission rates modified atmosphere package), and the 100g small unit with MA film on asparagus sensory quality were evaluated. The CO2 concentration depended largely on the packing unit and maintained at around 3% in small MA packages, whereas in the MA box increased to 12%. Ethylene concentration rapidly increased until after 3 days of storage in MA packages and then decreased to maintain 5μL·L-1. Unrelated to the unit size, the lower weight loss was obtained in MA packages. A significant difference in visual quality was shown since the 15th day, the best and worst were the MA box and small MA package on the finish day. Off-odor was the highest in small MA packages and the lowest in the carton box (< 3.0). Although there was no significant difference in firmness among all treatments, the packages showed the highest firmness in tips and stems, respectively. The sugar content and hue angle decreased during storage, but there was no statistical difference in all treatments. EL was lowest and highest in small MA package and carton box, respectively. On the 10th day, the total aerobic bacteria was lowest in small MA packages, but no significant difference on the 20th day. E. coli was not found in all treatments on the 10th day, while it was the lowest in the MA box on the 20th day. The mold and yeast were not observed during the whole storage. Based on the above results, the carton box packaged with 10,000cc OTR film was more effective in maintaining the quality of green asparagus with the suitable CO2 concentration for asparagus cold storage.

Due to abnormal weather conditions caused by climate change, natural disasters and damages are gradually increasing around the world. Global climate change as accompanied by warming is projected to exert adverse impact on production of potato, which is known as cool season crop. Even though, role of potato as a food security crop is expected to increase in the future, the climate change impacts on potato and adaption strategies are not sufficiently established. Therefore, this study was conducted to analyze the damage pattern of potatoes due to high temperature treatment and to evaluate the response of cultivars. T he high temperature treatment (35~38℃) induced heat stress by sealing the plastic house in midsummer (July), and the quantity and quality characteristics of potatoes were compared with the control group. T otal yield, marketable yield (>80 g) and the number of tubers per plants decreased when heat treatment was performed, and statistical significance was evident. In the heat treatment, 'Jayoung' cultivar suffered a high heat damage with an 84% reduction in yield of >80 g compared to the control group. However, in Jopung cultivar, the decrease was relatively small at 26%. Tuber physiological disturbances (Secondary growth, Tuber cracking, Malformation) tended to increase in the heat stress. Under heat conditions, the tubers were elongated overall, which means that the marketability of potatoes was lowered. T he tuber firmness and dry matter content tended to decrease significantly in the heat-treated group. T herefore, the yield and quality of tubers were damaged when growing potatoes in heat conditions. T he cultivar with high heat adaptability was 'Jopung'. T his result can be used as basic data for potato growers and breeding of heat-resistant cultivars.
This study was performed to investigate the reduction in bitter taste and quality characteristics by pretreatments (brining; 1, 5% and blanching; 1, 3 min) in pickled bitter melon, respectively. We prepared picked bitter melon samples at 1%-1 min, 1%-3 min, 5%-1 min, 5%-3 min. Total polyphenol and total flavonoid contents were found to be the highest in 5%-1 min at $14.23{\pm}0.40mg\;CE/g$ (dry) and $4.46{\pm}0.10mg\;RE/g$ (dry), respectively. L-ascorbic acid level was the highest in control samples. Arginine and glutamic acid were increased by brining and blanching. ABTS and DPPH radical scavenging activity were found to be the highest at $43.60{\pm}0.40$ and $44.88{\pm}0.20%$ at 5%-1 min, respectively. ${\alpha}-glucosidase$ inhibitory activity was the highest at 5%-1 min. The a value was statistically different, whereas L and b values were similar among different pretreatments. Hardness in pretreated samples was decreased as compared to that in the control. Among sensory evaluations, 'color' did not indicate any statistical difference, while 'texture', 'bitterness preference' and 'overall preference' increased with pretreatments, and 'bitter intensity' decreased.
