  • The purpose of this study is to analyze the effects of organizational communication satisfaction of teacher librarians on the informational and educational service and to draw implications for improvement of the school libraries' educational role. According to the results of the analysis, teacher librarians have preferred informal communication by conversation and face-to-face talk with superiors or co-workers and horizontal communication during their performance. Characteristics of teacher librarians, such as career, gender and school levels, have influential effect on user education, libraryassisted instruction, reading and information literacy instruction. The more teacher librarians felt satisfaction of the informal communication, the more textbook-related reference lists are offered. Horizontal communication have a positive influence on information literacy instruction. However, teacher librarians should utilize cooperative statements, committees and councils and actively participate in those horizontal communication methods to share the vision and aims of school libraries with the larger school community. Teacher librarians also should put more efforts into developing their leadership role and marketing strategies in order to overcome the weaknesses of informal communication.

  • The turbine system composed of a nozzle and a rotor is used to drive turbopumps while gas passes through the nozzle, potential energy is converted to kinematic energy, which forces the rotor blades to spin. In this study, an aerodynamic design of a turbine system is investigated using compressible fluid dynamic theories with some pre-determined design requirements (i.e.,pressure ratio, rotational speed, required power etc.) obtained from a liquid rocket engine (L.R.E.) system design. For simplicity of a turbine system, impulse-type rotor blades for open type L.R.E. have been chosen. Usually, the open-type turbine system requires low mass flow rate compared to the close-type system. In this study, a partial admission nozzle is adopted to maximize the efficiency of the close-type turbine system. A design methodology of the a turbine system has been introduced. Especially, a partial admission nozzle has been designed by means of simple empirical correlations between efficiency and configuration of the nozzle. Finally, a turbine system design for a 10 ton thrust level of L.R.E is presented.

  • This study aims to evaluate job satisfaction level of employees working at special libraries by analyzing their affiliated institution and personal backgrounds. Results indicated that the job satisfaction level in private institutions was higher for 'remuneration', 'promotion', and 'overall satisfaction' in comparison to public counterparts. Also, employees working at institutions with independent libraries had higher level of satisfaction for 'work itself', 'remuneration' and 'co-workers' in comparison to those working in non-independent libraries. In terms of employment status, satisfaction level for 'remuneration' and 'promotion' was high among permanent employees, whereas 'superior and supervisor' was relatively higher among temporary employees. In terms of position, supervisors had higher level of satisfaction for 'remuneration', 'job system', 'promotion' and 'overall satisfaction' in comparison to non-supervisors. Employees with degrees in library and information science had higher level of satisfaction for 'work itself', 'job system', 'promotion' and 'institutional environment' in comparison to non-majors. This study clarified desires and emotions of employees working at special libraries and eliminated obstacles to higher job satisfaction. These findings may have implications for the improvement of work efficiency in libraries.

  • Hotel employees' emotional exhaustion, depersonalization, and decreased sense of accomplishment lead to the Hotel Employees' Burnout Phenomenon(HEBP). Specifically, a higher stress level leads to an increased incidence of burnout among employees. This high level of burnout results in a decreased desire to work, and ultimately results in decreased service provision levels. In order to resolve the phenomenon, a healing program linked to psychotherapy may be introduced. This program would serve at the company level. In addition, encouragement and advice from seniors and colleagues are also needed. The psychological burden should be minimized by encouragement and compliments, rather than by the pressure for service quality improvement. Further, the employees' personal will to overcome the problem must be present.

  • The mainly objectives of this study was a combustion dynamics and instability characteristics in a model gas turbine dump combustor which is the scale down of GE 7FA+e DLN 2.6 gas turbine combustor. Model gas turbine injector has 2-stage swirl vane and it’s reduced 1/3 size of the original one. The shape of plenum and combustor were designed for similar acoustic characteristics. Inlet air was preheated to $200{\sim}400^{\circ}C$. The flow velocity at mixing nozzle was 30 to 75 m/s and equivalent ratio was 0.4 to 1.2. The combustor length was varied for different acoustic characteristics to $375{\sim}700\;mm$. As the result, this research have been show the combustion instability was observed at lower equivalence ratios ($\Phi$ < $0.5{\sim}0.6$) and higher equivalent ratios ($\Phi$ > $1.1{\sim}1.2$).

  • This study was intended to evaluate a post-operative relapse tendency in mandibular prognathism patients with open-bite. 18 patients with or without open-bite have undergone sagittal split ramus osteotomy and were investigated radiologically with cephalogram. The results were as following 1. The preoperative anterior facial height, mandibular plane angle and mandibular gonial angle were larger in open-bite patients than in nonopen-bite patients.(p>0.05) 2. There was significant correlation between surgical change of SNA, mandibular plane length and long-term relapse.(p<0.01). 3. There was relatively stable postoperative anterior facial height in open bite patients. 4. There was no significant correlation between the surgical change of mandibular plane angle, amount of mandibular setback and long-term relapse.(p>0.01) 5. This study showed that horizontal relapse was more significant than vertical relapse.

  • The purposes of this study were to identify the causal effects of distributive fairness, procedural fairness and interactional fairness on abusive supervision and the causal ones of abusive supervision on organizational citizenship behavior(OCB). Also this study aimed to investigate the mediating effects of abusive supervision on the causal relationships between three fairnesses and organizational citizenship behavior. The sample of this study were customer-contact employees of restaurants among Youngnam province. 376 questionnaires were used for the empirical analyses. According to the research findings, distributive fairness and interactional fairness had negative influences to abusive supervision and abusive supervision had a negative influence to OCB. Another research findings were that abusive supervision had the mediating effects on the causal relationships between two fairnesses(distributive and interactional) and organizational citizenship behavior. Managerial implications of the research findings are that restaurant managers should set up the organizational culture of respecting employees each other and provide training for the level of supervisor to foster the organizational culture. In the field of restaurant industry, training is very important for employees to foster this organizational culture as this industry has the environment of becoming abusive supervisor for the reason of supervisors' being exposed to lots of physical and psychological burden of works.

  • The purpose of this study is to determine abusive supervision and its effect on the resistance to such behavior by workers, and also to determine the moderating roles of subordinate's personalities that can strengthen or weaken the relationship between the abusive supervision and employee behaviors. Because the key factors underlying the choice of individual OCB(Organizational Citizenship Behavior) or organizational OCB have to do with subordinates' concern for the task and relational consequences of their behavior, the analysis focused on Neuroticism, the Big Five domains that represent one's orientations toward task and relational matters, respectively(Costa & McCrae, 1992). For empirical study, survey was performed for the analysis, and a total of 233 was used. The following is a summary of the verification results. First, in the relationships between the use of abusive supervision and employee's OCB, the relationship is negatively correlated to the abusive supervision. Second, moderating effects of subordinates' personalities(neuroticism) between abusive supervision and subordinates' were not verified. Finally, future research will explore the effects of situational variables that affect the extent to which supervisors engage in abusive behavior and how subordinates respond to abusive supervision.

  • The osteological characters of Aphyocypris chinensis of subfamily Leuciscinae were examined and the systematic position of this species is discussed through comparison with other species of subfamilies Leucisicinae and Cultrinae. Numbers of the dorsal an danal fin ray, having no symphyseal knob and barbels and separation between dermosphenotic and supraorbital, are in acord with those of subfamily Leuciscine, and the abdominal keel and trigemino-facial nerve foramen of the prootic are more closely related with those of subfamily Cultrinae. But several diagnostic characters detected only in this species are as follows ; 4 infraorbitals, the shape of ethmoid, 5-6 hypurals, the broad orbital width, having no extrascapular, incomplete lateral line and considerable small size.
