Purpose : We examined the relationship between BIS, sedation score and plasma midazolam concentration to verify the usefulness of BIS to assess the patient's consciousness during sedation. Patients and Methods : Twenty-five young, healthy adult volunteers participated in this clinical study. Midazolam was administered intravenously up to 0.08 mg/kg to induce unconsciousness and we monitored the patient's physiological and conscious status until complete recovery from sedation. BIS and sedation score were measured before sedation, 10, 20, 30 minutes after midazolam administration. Plasma midazolam concentration was measured 10 minutes after midazolam administration. BIS was measured using A-2000 BISTM monitor (Aspect Medical Systems, USA) and the degree of sedation was evaluated with the sedation score. Results : The BIS score correlated with the sedation score (r = 0.676; P < 0.05). With the decreased plasma midazolam concentration, the correlation was better with sedation score (r = -0.656). Although BIS values did not correlate with calculated plasma concentration of midazolam (r = 0.467) at 10 minutes after midazolam administration, values after sedation were well distinguished from those before sedation. Conclusions : BIS is known for an effective predictor of patient's hypnotic state, and it is correlated with the sedation score. But, it doesn't always coincide with the clinical parameters of depth of sedation. So more attention is needed using BIS only during sedation, and it is advisable that the patient's consciousness is monitored with variable sedation score systems every several minutes.

To compare the sedative effects using intermittent intravenous bolus injection with tiletamine-zolazepam (n = 5, TZ group), xylazine-ketamine (n = 5, XK group) and propofol (n = 5, PI group), we investigated the changes of hemodynamic (heart rate, arterial pressure), $SpO_2$, rectal temperature, respiratory rate and pain score during 60 minute sedation and 40 minute recovery period in beagle dogs. The value of rectal temperature was significantly higher in PI groups (p<0.05) during recovery period. The value of heart rate was significantly lower in XK group (p<0.05) during sedation. The changes of respiratory rate were similar tendency in all groups. The change of $SpO_2$ was stable during sedation and value was significantly higher in PI group (p<0.05) during recovery period. The value of systolic arterial pressure (SAP) was significantly lower in XK group (p<0.05) than PI group during sedation and recovery period. Low analgesic effect occurred in PI group. We concluded that intravenous anesthesia by intermittent bolus injection with propofol is useful in stabilizing rectal temperature, $SpO_2$ and hemodynamic during sedation and provide fast recovery, but have low analgesic effect.

This study examined effects of self-esteem, life satisfaction and gender on the sign needs which included self-presentation(presenting true-self and ideal-self) and social interaction (feeling connected and gaining approval) for Facebook use. Due to the significant interaction effects of gender, further statistical analyses were conducted. While there were negative relationships between self-esteem and self-presentation for male respondents, there were positive relationships between self-esteem and social interaction for female respondents. In addition, there were positive relationships between life-satisfaction and self-presentation for male respondents, but there was the only positive relationship between life satisfaction and presenting true-self for female respondents. Based on the study results, the study implications, limitations and future study were discussed.

The reality which cannot protect existing tangible intangible modern cultural heritage in Daejeon is makes historical value and identity of a city weakened and then, this leads to absence of the foundation of urban regeneration based on the history. References as recording inheritance indicates characteristics or identity of the area and they represent the physical mental symbol of the area; images of diverse structures or sceneries with historical or cultural characteristics are contents of urban regeneration based on history and culture, which can be utilized as historical sources to verify realness of disappearing modern cultural heritage. Therefore, understanding and utilization of modern cultural heritage through this study on regional archiving can be deemed to be the first stage to bring community spirit, affection and pride to local residents. In this connection, this study intends to suggest a policy direction not only to maintain realness of modern cultural heritage through preservation and utilization but also to expect formation of settling and fellowship as well as cultural economical effect from the viewpoint of urban regeneration.

The primary objective of this study was to develop an optimal composite recipe for ginger extract candy with Salicornia herbacea L., for consumption during the first trimester of pregnancy. The secondary objective was to examine quality characteristics of the candy. The physical and mechanical properties and sensory properties for pregnant women in were measured, and these values were applied to mathematical models. Time of stirring water solution, saltiness, pH, and redness of the candy increased as concentrations of ginger juice did, but variations in pH were not significant. The hardness values of the candy ranged from 3,063.90 to $5,681.65dyne/cm^3$. The average values of sweetness and time stirring the water solution were 5.36% and 14.1 minutes, respectively. However, hardness and sweetness stirring water solution were not significant. The range of sensory values of color (P<0.01), flavor (P<0.05), sweetness, saltiness, spiciness, and overall quality (P<0.05) ranged from were 3.73~5.32, 4.05~5.05, 3.67~5.14, 3.59~5.09, 3.55~5.15, and 3.32~5.45, respectively. Results suggest that ginger extract candy with Salicornia herbacea L. should be comprised of 7.37 g of ginger juice and 1.77 g of salt. Consequently, it could be a functional candy for pregnant women.

It is very important for companies to form a strong brand resonance to maximize profits, attract new customers, and prevent them from leaving existing customers. In this study, we examined the relationship between brand awareness factors and brand attachment leading to brand identity cognition, brand performance, and brand emotion, and verified how brand attachment plays a role in shaping brand resonance. As a result, it was confirmed that brand emotion among brand awareness factors is a key factor affecting brand attachment and forming brand resonance. In addition, if the perception of brand identity is established until the true brand resonance of consumers is established, they will experience the true value of the brand through differential performance on the brand, and further increase the emotional response of consumers. This led to deep solidarity with the brand and consumers through attachment to the brand, interacting with the brand and showing high brand empathy behavior.

The purpose of this paper is to develop and suggest an integrative leadership contingency framework of leadership that will state the situational and psychological factors under which leadership effect should be maximized. Our leadership model presents that situational factors, including development, circumstances urgency and task structure, proposes which of transformational, transactional, empowering, and authentic leadership solutions. Also, our integrative leadership contingency model in turn results in a combination of the level of follower commitment, intrinsic motivation, and individual creativity based on inductive research method. This integrative leadership model suggested here has significant contributions for leadership effectiveness and future leadership research agenda. Next leadership research could experimentally examine the structural relationships between each of the leadership styles and levels of contingency and psychological factors of followers.

The ppuri industry is growing in technical importance due to the 4th industrial revolution and is growing steadily. However, securing skilled workers is hardly realistic, and foreign workers are increasing. The purpose of this study is to find organizational commitment on for improvement of in-role performance of foreigners and Koreans working in ppuri companies and to find ways to support differentiation through comparison between groups. The subjects of this study were foreigners and Koreans in the ppuri company. Through the survey, 393 valid samples were collected. We use structural equation modeling to verify the research hypotheses, and conducted a survey on the employees of organization with information security policy. The results showed that in the case of foreigners, balanced processing affects in-role performance through organizational commitment. In the case of Koreans, relational transparency, balanced processing, and internalized moral perspectives affect in-role performance through organizational commitment. The results of the analysis suggest a strategic approach to improve the in-role performance of each group.

Background: The purpose of this study was to compare the clinical safety and effect with and without additional submucosal midazolam to oral chloral hydrate and hydroxyzine when used for pediatric conscious sedation in a clinical dental environment. Methods: Thirty one cases of pediatric conscious sedations were performed in this study. Selection criteria included good health (ASA I), under 6 years old, 20 kg of body weight, uncooperative behavior and the need for sedation to receive dental treatment including anesthesia and restorative or surgical procedure for at least two teeth. In each visit, patients were randomly assigned into one of two groups; CH group: chloral hydrate (60 mg/kg), hydroxyzine (1 mg/kg), CH-M group: chloral hydrate (60 mg/kg). hydroxyzine (1 mg/kg) and submucoal midazolam (0.1 mg/kg). 50% nitrous oxide-oxygen was maintained during the sedation period Sedations were monitored using a pulse oximeter for estimating pulse rate (PR) and percutaneous oxygen saturation ($SpO_2$). Behavior response rated using Houpt's scale and need of restraint was assessed every 2 minutes through 30 minutes of operative procedure reviewing the videotape recording. Evaluation of overall behavior success was performed using modified overall behavior rate of Houpt's scale. Data was analyzed using t-test. Results: PR and $SpO_2$ for both groups remained within the normal values. The mean scores for sleep and movement of CH-M group were higher than those of CH group (P < 0.05). There were no significant difference in mean score for crying between two groups. The mean scores of overall behavior of CH-M group was higher than those of CH group (P < 0.01). Reinstraint of CH-M group was less required than that of CH group (P < 0.05). Conclusions: Oral chloral hydrate (60 mg/kg) and hydroxyzine (1 mg/kg) combined with submucosal injection of midazolam was safer and showed more improved sedation effect than oral chloral hydrate (60 mg/kg) and hydroxyzine (1 mg/kg) without midazolam for sedation of pediatric dental patients.

This is an attempt to reflect on humanity in the post-human era. Here, I think that the question of future human beings should be critically raised in the following two meanings. First, can post-humans recover the body, emotions, nature and women's voices suppressed by modern enlightened subjects? Second, can post-humans preserve humanity by fighting inhumanity without presupposing human essence or immutable foundations? In answer to these questions, I will have a dialogue with M. Heidegger(1889-1976), W. Benjamin(1892-1940), Th. W Adorno(1903-1969). The three philosophers looked at the inhuman world situation brought about by modern subjects and technology, and found the possibility of new human beings. The three philosophers' new human image are the three possible models of post-humanism, 'a human being as ek-sistence' (Heidegger, Chapter 2), 'the man who restored the similarity with the other through innervation' (Benjamin, Chapter 3), 'A human being who negates the inhuman society' (Adorno, Chapter 4), and examines the current status of each. In conclusion, as long as the fourth industrial revolution is developed as a system of digital capitalism that controls the world as a whole from human senses, impulses, and unconsciousness, the necessity of the post-human era is aesthetic authenticity.
