  • Purpose - Turnover Intention in the franchise industry is becoming a very important issue. This study examines the structural relationships between organizational justice, emotion, job satisfaction, and turnover intention in the franchise industry. In this model, emotion was classified into two sub-dimensions such as positive and negative emotion. Research design, data, methodology - The sample of this study collected from employees of a food-service franchise company is representative. Copies of the questionnaire along with a cover letter were delivered by a research assistant to the human resources manager or the general manager of the selected food-service franchise firms after they agreed to participate in the study. In order to increase the response rate of the respondents, a small gift was provided to the respondents who completed the questionnaire. A total of 300 questionnaires were distributed and 285 returned responses, 9 responses were not usable due to missing information. Thus, a total of 276 responses were used using structural equation modeling with Smartpls 3.0. Results - The results showed that organizational justice had positive significant effects on positive emotion and job satisfaction. Job satisfaction had negative a significant effect on turnover intention. And negative emotion had positive significant effect on turnover intention. Conclusions - The results of this study provide some implications. If employees feel that the franchise headquarters is fair about the methods and procedures of decision making, resource allocation, information sharing, etc., it means that employees feel better. If the franchise's decision-making processes and methods and results are transparently disclosed and processed in accordance with the internal rules of the company, the employees will be able to fully understand and accept them. The results of this study also show that positive and negative emotions of service-based franchise employees have different effects on job attitude and organizational behavior. In particular, when negative emotions of employees are passed on to others and the results are negative, employees may feel that they are disoriented or wrong. Therefore, the franchise headquarters should try to inspire employees' sense of organizational community, and should pay attention to how to relieve the job stress and the fair distribution of work and rewards.

  • The present study was attempted to investigate the effects of total ginseng saponin (G75), panaxadiol-type (PDS) and panaxatriol-type saponin (PTS) on contractile responses of vasoconstrictors in aortic smooth muscle stripes of normotensive (NR) and spontaneous hypertensive rats (SHR). Phenylephrine (an adrenergic $\alpha$$\_$1/-receptor agonist) and high potassium (a membrane depolarizing agent) caused greatly contractile responses in both NR and AHR aorta, respectively. Phenylephrine- and high potassium-induced contractile responses were greater in NA than those in SHR aortic smooth muscle stripes. In NR, the contractile responses of high potassium (5.6$\times$10$\^$-2/ M) were not affected in the presence of GTS (300 $\mu$g/ml), PDS (300 $\mu$g/ml), and PTS (300 $\mu$g/ml), respectively whereas phenylephrine (10$\^$-6/ M)-induced contractile responses were markedly inhibited. In SHR, the contractile responses of high potassium (5.6$\times$10$\^$-2/ M) were not affected in the presence of GTS (300 $\mu$g/ml), PDS (300 $\mu$g/ml), and moderate doses of PTS (150-300 $\mu$g/ml), respectively but greatly blocked by high concentration of PTS (600 $\mu$g/ml). Phenylephrine (10$\^$-6/ M)-induced contractile responses were inhibited in a dose dependent fashion (150-600 $\mu$g/ml) by the pretreatment with PTS while not altered in the presence of GTS (300 $\mu$g/ml) and PDS (300 $\mu$g/ml), respectively. Taken together, these experimental results suggest that ginseng saponins cause vascular relaxation through blockade of adrenergic $\alpha$$\_$1/-receptors and some unknown mechanisms, and that there is some difference in sensitivity of vascular smooth muscle between NR and SHR in responses to ginseng saponins. It seems that panaxatriol type of some ginseng saponins has the greatest potency in vascular relaxation.

  • Physiological effects in SAM P6 and Rl by administration of Cervus cornu, Astragali Radix, Rehmanniae Radix, and Angelicae Radix extracts were screened to know in vivo activities of each extracts. We measured complete blood cells (CBC) such as aBC, HGB, and HCT using coulter's method. Plasma concentrations of albumin, glucose, alkaline phosphatase, calcium, creatinine, inorganic phosphate, urea and total iron ere also analyzed using biochemical clinical autoanalyzer. Plasma concentrations of cortisol, total T$_3$, and total T$_4$ were measured by chemiluminescent immunoassay methods. At 12 weeks after birth, Cervus conu or Astragali Radix or Rehmanniae Radix extracts were given 5 g/Kg.day p.o. for 0,7,14,21, and 30 days each in both SAM Rl and SAM P6. Angelicae Radix study was done the same as the others except the mice were 16 weeks after birth. The RBC, HGB, and HCT levels after administration of Astragali and Rehmanniae were elevated in SAM Rl, but those in Cervi study were increased in SAM P6 the most. Decreases in alkaline phosphatase concentration of SAM Rl and P6 after Cervi administration were detected. Total plasma iron concentration was decreased by Angelicae administration in SAM P6. In general, Angelicae and Rehmanniae stimulate increases in cortisol, but total T$_3$ and T$_4$ levels were also elevated by all these extracts. In conclusion, these herval medicine extracts help hematopoiesis in SAMs through probably different mechanisms.

  • This paper concerns about total dynamic analysis of integrated mining system. This system consists of vertical steel pipe, intermediate buffer station, flexible pipe and self-propelled miner. The self-propelled miner and buffer are assumed as rigid-body of 6-dof. Discrete models of vertical steel pipe and flexible pipe are adopted, which are obtained by means of lumped-parameter method. The motion of mining vessel is not considered. Instead, the motion of mining vessel is taken into account in form of various boundary conditions (e.g. forced excitation in slow motion and/or fast oscillation and so on). A terramechanics model of extremely soft cohesive soil is applied to the self-propelled miner. The hydrodynamic forces and moments are included in the dynamic models of vehicle and lifting pipe system. Hinged and fixed constraints are used to define the connections between sub-systems (vertical steel pipe, buffer, flexible pipe, miner). Equations of motion of the coupled model are derived with respect to the each local coordinates system. Four Euler parameters are used to express the orientations of the sub-systems. To solve the equations of motion of the total dynamic model, an incremental-iterative formulation is employed. Newmark-b method is used for time-domain integration. The total dynamic responses of integrated mining system are investigated.

  • The purpose of this study was to investigate 119 rescue party's violence experiences and to analyze their responses of violence experiences based on the pre-hospital emergency medical field. Data were collected from the self-administered survey of 226 rescue party in Jeollabuk-do area in Korea from January 1 through March 2, 2009. The data were analyzed by descriptive statistics and logistic regression analysis using SPSS Win 12.0. The results were as follows: first, all of 119 rescue unit in the pre-hospital emergency medical field reported that they got violence experiences more than once a week, and 62% of rescue team were exposed to physical violence. Patient's factors that caused violence were drug abuse or alcohol(56.2%), on the other hand rescue party's factors were shortage of human resources. Second, 42% of the respondents replied that they did not have any educational experiences for prevention and coping methods about violence within 5 years. 77.4% of those surveyed indicated that they wanted to receive specific educations which can prevent and cope with violence. Third, the mean value of total violent response scores was 2.53, and emotional response score was 3.2, social response score was 2.22, and physical response score was 2.17. Fourth, violent response score related to general characteristics proposed that physical(t=-2.08, p=o.38), emotional(t=-7.13, p=.006), and total responses(t=-4.764, p=.000) were statistically significant. And emotional(t=4.257, p=.000) and total responses(t=8.1330, p=.000) related to age were also statistically significant. Finally, among current tenure qualification scores, social response(t=9.987, p=.012) and total score(t=8.130, p=.000) were statistically significant. Between fire departments, violent response score suggested that physical(t=9.987, p=.000), emotional(t=2.433, p=.012), social(t=6.738, p=.000), and total score(t=5.943, p=.000) were statistically significant.

  • The aim of the present study was to test the efficiency of estrous induction in the premature, metestrous and anestrous bitches. The estrus was induced with prostaglandin $F_{2{\alpha}}$, estradiol-$17{\beta}$, pregnant mare serum gonadotropin (PMSG) and human chorionic gonadotropin(HCG) in the treatment A, and with PMSG and HCG in the treatment B. Day 0 was the first day of estrone injection in the treatment A and the day of PMSG injection in the treatment B. Twenty three of the twenty six bitches were laparotomized under general anesthesia between 11 and 18 days after onset of behavioral estrus, whereas three bitches were not laparotomized and remained until parturition. Ovarian responses were evaluated with the total number of corpora lutea or ovulation sites. The uterine horns were flushed with phosphate-buffered saline added heat treated canine serum(10%), the flushing media was collected into watch glass and the ova were examined under stereomicroscope. The results obtained were as follows: 1. Standing estrus was observed on the day $17.7{\pm}1.5$ after injection of estrone in the treament A, but ovarian responses were not detectable. 2. Standing estrus was observed on the day $12.2{\pm}0.2$ after injection of PMSG in the treament Band 14 of 17 bitches showed ovarian responses. Ova were recovered in 9 of the 14 bitches. 3. Ovarian responses were observed in one of the three premature bitches. two of the three metestrous bitches and all of the 11 anestrous bitches. The average number of the ova collected from 9 bitchs were $12.2{\pm}1.4$. 4. Three bitches in the treament B exhibited behavioural estrus and all of them were mated with fertile male dog, resulting the pregnancy in only one bitch. The pregnant bitch gave the birth of two pups.

  • Purpose: To investigate whether pretreatment serum carbohydrate antigen 19-9 (CA 19-9) levels are associated with pathological responses to preoperative chemoradiotherapy (CRT) in patients with rectal cancer. Materials and Methods: In total, 260 patients with locally advanced rectal cancer (cT3-4NanyM0) who underwent preoperative CRT and radical surgery were analyzed retrospectively. CRT consisted of 50.4 Gy pelvic radiotherapy and concurrent chemotherapy. Radical surgery was performed at a median of 7 weeks after CRT completion. Pathological CRT response criteria included downstaging (ypStage 0-I) and ypT0-1. A discrimination threshold of CA 19-9 level was determined using a receiver operating characteristics analysis. Results: The median CA 19-9 level was 8.0 (1.0-648.0) U/mL. Downstaging occurred in 94 (36.2%) patients and ypT0-1 in 50 (19.2%). The calculated optimal threshold CA 19-9 level was 10.2 U/mL for downstaging and 9.0 U/mL for ypT0-1. On multivariate analysis, CA 19-9 (${\leq}9.0U/mL$) was significantly associated with downstaging (odds ratio, 2.089; 95% confidence interval, 1.189-3.669; P=0.010) or ypT0-1 (OR, 2.207; 95%CI, 1.079-4.512; P=0.030), independent of clinical stage or carcinoembryonic antigen. Conclusions: This study firstly showed a significant association of pretreatment serum CA 19-9 levels with pathological CRT responses of rectal cancer. The CA 19-9 level is suggested to be valuable in predicting CRT responses of rectal cancer cases before treatment.

  • Purpose: This study investigated accommodative changes by measuring accommodative response, appearing on the normal and convergence insufficiency Group, by using both eyes open-view auto-refractometer (Nvision-K5001, shin-nippon, Japan). Methods: It carried out objective and subjective refractions, targeting 74 college students (54 males and 20 females) aged between 19 and 29 ($21.59{\pm}2.53$), spherical equivalent OD $-2.28{\pm}2.03$ D, OS $-2.18{\pm}2.01$ D, by measuring accommodative responses at full correction and under correction with plus lens +0.25, +0.50, +0.75 arbitrarily added. Results: In the group of normal and convergence insufficiency, the shorter fixation distances were, the greater accommodative lags showed. The group of convergence insufficiency showed the lesser changes of accommodative response than those of normal. But we found that the convergence insufficiency group had a little larger accommodative amplitude in the total fixation distances. The full correction of convergence insufficiency group and the under correction (+0.50 D) of normal were alike in the accommodative responses. We have also investigated that the correlation between accommodative responses and fixation distances was decreased steeply at the excessive low vision correction. Conclusions: Under correction (+0.50 D) in a near distance is expected to avoid unnecessary accommodative responses, make eyes relaxed and comfortable.

  • This study was designed to investigate the effects of multi-enzyme on diarrhea and immune responses of weaned pigs. A total 36 weaned pigs ($5.92{\pm}0.48kg\;BW$; 28 d old) were randomly allotted to 2 dietary treatments (3 pigs/pen, 6 replicates/treatment) in a randomized complete block design. The dietary treatments were a typical diet based on corn and soybean meal (CON) and CON with 0.1% multienzyme (Multi; mixture of ${\beta}-mannanase$, xylanase, ${\alpha}-amylase$, protease, ${\beta}-glucanase$, and pectinase). Pigs were fed their respective diets for 6 wk. Frequency of diarrhea, levels of packed cell volume (PCV), white blood cells (WBC), immunoglobulins, cortisol, tumor necrosis $factor-{\alpha}$ ($TNF-{\alpha}$), transforming growth $factor-{\beta}$ ($TGF-{\beta}$), and C-reactive protein (CRP) were measured. Multi group tended to decrease (p<0.1) diarrhea frequency than CON group during 2 wk after weaning. Lower values of PCV on d 3 (p<0.05) and d 7 (p<0.1) were found in Multi group compared with CON group. There were no significant differences on WBC number and immunoglobulin (Ig) M and A between Multi and CON groups. However, Multi group tended to increase (p<0.1) Ig G on d 7 than CON group. Moreover, Multi group showed modulated immune responses, indicated by decreased levels of cortisol (p<0.05) on d 7 and 14, $TNF-{\alpha}$ on d 3 (p<0.05) and d 7 (p<0.10), $TGF-{\beta}$ on d 2 (p<0.05) and d 7 (p<0.10), and CRP (p<0.10) on d 3 and 7 after weaning compared with CON group. Consequently, inclusion of multi-enzyme in diets for weaned pigs improved gut health and modulated immune responses of weaned pigs.
