The reconstruction of deep soft tissue defect such as pressure sore has difficult problems. Myocutaneous flaps have been used commonly as the best coverage method for pressure sore. But, they have several drawbacks such as sacrifice of functional muscle, high morbidity of the donor sites and bulkiness at the recipient site. The concepts of perforator flap has recently developed and widely used to overcome these disadvantages. Between March 2005 to July 2006, we have treated 9 patients who had pressure sore using perforator based fasciocutaneous island rotation flap. Preoperative unidirectional Doppler was used in all cases. Mean number of perforator vessels was 3.8 and flap sizes were from $7{\times}5\;cm$ to $14{\times}13\;cm$. Rotation angles of flap were from 90 degree to 180 degree. In all cases, donor sites were closed primarily. All flap survived completely and postoperative complications were wound dehiscence in 1 case, wound infection in 3 cases. The mean postoperative follow up period was 15.7 months and recurrence was not reported. We could decrease donor site morbidity and cover wound sites easily by using flap rotation and get robust blood supply without sacrifice of functional muscle. Fasciocutaneous perforator island rotation flap would be very useful for various pressure sore treatment.

Acute betaine treatment induces time-dependent changes in the hepatic glutathione (GSH), cysteine and S-adenosylmethionine (SAM) levels. Our previous study demonstrated that betaine administered $1{\sim}4$ hours prior to sacrifice decreased hepatic GSH levels, but these levels were increased when measured 24 hours following the treatment. The present study was aimed to determine dose-dependent effects of betaine on hepatic metabolism of sulfur amino acid in mice. Mice were sacrificed 2.5 or 24 hours after intraperitoneal treatment with betaine at different dose levels ranging from 50 to 1000 mg/kg. The concentrations of methionine and SAM were increased by a betaine dose of 100 mg/kg, and the concentrations of GSH and cysteine were decreased by a betaine dose of 200 mg/kg at 2.5 hours. These changes were augmented with increasing doses of betaine. At 24 hours following betaine treatment, increased GSH and decreased taurine levels were observed from dose levels of 400 mg/kg. Changes in hepatic activities of cystathionine beta-synthase, gammaglutamylcysteine ligase and cysteine dioxygenase were observed from dose levels of $200{\sim}400$ mg/kg of betaine administered 24 hours prior to sacrifice.

In vivo antagonistic effect of Lactobacillus helveticus CU 631 and Lactobacillus spp. against typical enteritis causing pathogen Salmonella enteritidis KU 101 have been determined, which showed an increase in survival rate and the decline in viable cell numbers of pathogen in liver and spleen at sacrifice. A signifcant difference in the antagonistic effect against KU 101 were observed, which was species and/or strain dependent of Lactobacillus (p<0.01), the survival rate of the mice in the Salmonella infection by feeding L. helveticus CU 631 has been shown to be 157%, whereas those of L. rhamnosus GG ATCC 53103, L. acidophilus ATCC 4356, L. johnsonii C-4 were 137%, 132%, 119% respectively on the basis of lactobacilli non-associated control KU101 fed mice to be 100%. Viable cells of S. enteritidis KU101 in the liver and in the spleen at sacrifice were decreased in Lactobacillus spp. fed group with no significant difference. The higher level of total secretory IgA concentration in the intestinal fluid of lactobacilli fed mice than control mice have been observed. In vitro antagonistic activity of Lactobacillus spp. against KU101 have been determined, a prominent antagonistic activity of CU 631 against KU 101 were demonstrated.

In this paper, we propose a smart thermostat temperature set-point control method based on machine learning and rule engine, which controls thermostat's temperature set-point so that it can achieve energy savings as much as possible without sacrifice of occupants' comfort while users' preference usage pattern is respected. First, the proposed method periodically mines data about how user likes for heating (winter)/cooling (summer) his or her home by learning his or her usage pattern of setting temperature set-point of the thermostat during the past several weeks. Then, from this learning, the proposed method establishes a weekly schedule about temperature setting. Next, by referring to thermal comfort chart by ASHRAE, it makes rules about how to adjust temperature set-points as much as low (winter) or high (summer) while the newly adjusted temperature set-point satisfies thermal comfort zone for predicted humidity. In order to make rules work on time or events, we adopt rule engine so that it can achieve energy savings properly without sacrifice of occupants' comfort. Through experiments, it is shown that the proposed smart thermostat temperature set-point control method can achieve better energy savings while keeping human comfort compared to other conventional thermostat.

The purpose of this study was to measure the effects that service quality, perceived value and satisfaction have on loyalty in Namhaean area restaurants. A total of 273 questionnaires were completed. The structural equation model was used as an analysis method to measure the causal effects of service quality, perceived value, satisfaction and loyalty. The results demonstrated that the structural analysis result for the data was an excellent model fit. The effect of service quality on value, the effect of perceived sacrifice on value, the effect of service quality on satisfaction, the effect of value on satisfaction, and the effect of satisfaction on loyalty were statistically significant. Moreover service quality had an indirect effect on satisfaction through perceived value, and service quality also had an indirect effect on loyalty through perceived value and satisfaction. Perceived value had an indirect effect on loyalty, and an effect through satisfaction. Perceived sacrifice had an indirect effect on satisfaction through perceived value, and it also had an indirect effect on loyalty, and an effect through satisfaction. Further study is still required, and should be aimed at identifying the causal mechanisms of constructs, such that restaurant managers might be better prepared to offer value and satisfaction to their customers.

In recent years, O2O (Online to Offline) services get a lot of attention to improve the trust in online shopping and minimize the inconvenience and the cost burden in offline shopping as the number of consumers, who do not show concern about the purchase platform like online or offline, increases. Even though the services have been getting the spotlight as a strong business platform for next generation commerce, there have been only a few studies on the O2O services. The purpose of this research is to investigate the factors which affect the consumer's intention to use location-based O2O services. The study is based on VAM (Value-based Adoption Model) which is able to analyze those factors from the aspects of benefit and sacrifice. We used the partial least squares (PLS) method for empirical analysis, and the result shows that contextual offers, instant connectivity, webrooming and economic efficiency, which fall under the benefit, affect perceived value positively while annoyance and face consciousness, which fall under the sacrifice, do not affect perceived value significantly. In addition, contextual offers and instant connectivity affect trust positively. Location accuracy, which falls under the benefit of location-based O2O service, do not significantly affect perceived value and trust while security risk affects trust and use intention negatively. It appears that trust affects perceived value and use intention positively.

The purposes of this study is to derive the influence factors of Virtual Reality(VR) technologies acceptance based on the study of unified theory of acceptance and use of technology and value-based acceptance model to test the use and acceptance of VR devices. The survey methods were used for this study, and the data from a total of 400 consumers were used for the analysis. And the structural equation model was used to analyze the data. The results of the study are as follows: First, benefit components perceived enjoyment(EN) and sacrifice components personal innovative(PI) of VR devices were positively related to perceived values and use intention of VR devices, although the benefit components performance expectancy(PE) was positively related to perceived values(PV) but was not positively related to the use intention of VR devices. Second, sacrifice components perceived cost(PC) and anxiety(ANX) of VR devices were negatively related to perceived value(PV), but were not negatively related to the use intention of VR devices. Third, perceived values was not obvious related to the use intention(UI) of VR devices. The results of this study contribute to the literature as a new attempt to examining the effect on consumer use intention in VR technology areas.

This article compares the concepts of divine incarnation as expounded in Daesoon Thought and in Christianity and questions the essence of the divinity in both traditions. In Daesoon Thought, The Supreme God, Sangje, saw major disorganization leading to extreme violence and doom and decided to incarnate on earth under the human form of Kang Jeungsan (1871-1909). Then the living God taught the solution to human suffering through the revelations he sent in 1917 to Jo Cheol-Je, or Jo Jeongsan (1895-1958) and the revelations were passed on to Dojeon Park Wudang who in 1969 founded Daesoon Thought. In Christianity, God incarnated in his son, Jesus Christ, who allowed for the radical transformation of the condition of man through his physical sacrifice. Daesoon differs in that Sangje did not offer himself as sacrifice when he came on earth but reorganized the world and taught how to apply benevolence to establish the Earthly Paradise. The affirmation that Daesoon Jinrihoe is both monotheistic and polytheistic is then analyzed. If the concept of monotheism seems to differ vastly between the two traditions, it appears that biblical monotheism is itself relatively young in the history of world religions so that Christianity has ancient roots germane to those of Daesoon Jinrihoe. The article concludes on the originality of this religion: though it is built on Daoism, Buddhism and Confucianism, it has transformed their vision of the deity and of its message in a most convincing manner.

Purpose: Public sector is usually not an attractive career choice for the youths, due to the uncompetitive income and the working environment. Therefore, understanding the motivations of the Generation Z, the currently early-career employees, to work in the public sector is important. This research aims to address a gap in the literature on the linkage between Personality Traits of Generation Z and Public Service Motivation (PSM). Research Design, Data, and Methodology: Using the sample of Vietnamese generation Z, it shows how individual personality, as defined by the Big Five, affects PSM. A quantitative survey of 355 university students, who are members of this generation and are preparing to join the labor market, was undertaken. We used SEM to examine the results. Results: Our findings show that Agreeableness, Neuroticism, and Conscientiousness are significant antecedents of PSM. Agreeableness, which leads to three PSM dimensions, namely Compassion, Self-Sacrifice, and Commitment to Public Values, is the best predictor of this motivation. Meanwhile, Neuroticism and Conscientiousness only affect the dimension of Compassion. Conclusion: This study adds to the limited current knowledge on the personality-PSM relationship among generation Z. The distribution of affective (Compassion, Self-Sacrifice) and norm-based (Commitment to Public Values) motives provide insight for both career counselors and recruiters in public service delivery.
