The purpose of this study is to identify what kind of leadership styles on travel agency empirically. Also described are the relationship between these leadership styles and the job satisfaction, the organizational commitment of employee. Leadership is divided into two categories(transactional leadership and transformational leadership). Transformational leadership was more deeply analyzed and the empirical analysis was conducted to apply into the service industry. But we have some other results. In conclusion, there is no leadership style which could be applied in every condition and all kind of leadership should be applied case by case.

연구목적: 정신과 전문병원에 입원해 있는 만성정신분열병 환자들을 대상으로 첫째 지연성 운동장애의 유병율과 위험인자들을 조사하고, 둘째 지연성 운동장애와 정신분열병의 음성증상 및 인지기능 장애와의 상관성을 조사하고자 한다. 방법: 연구대상자는 마산동서병원에 입원 중인 환자 중 DSM-IV의 정신분열별 진단기준에 부합하며, 최근 3개월 이상 동일 용량의 항정신병약물 복용한 271명(남자 174명, 여자 97명)의 환자들이었다. 지연성 운동장애에 대한 평가는 Abnormal Involuntary Movement Scale(AIMS)을 이용하였고, DSM-IV와 Sc-hooler와 Kane(1982)의 진단기준 양자에 부합하는 환자들만을 지연성 운동장애군으로 분류하였다, 정신 분열병 정신병리에 대한 평가는 Brief Psychiatric Rating Scale(BPRS)와 Schedule for the Deficit Syndrome(SDS)을 이용하였고, 인지기능에 대한 평가는 Mini-Mental Status Examination(MMSE)을 이용하였다. 결과: 지연성 운동장애의 유병율은 50.9%이었고, 50세 이상, 남자에서 높았다. 그러나 입원기간과 항정신병 약물의 일일 사용량에 따른 차이는 없었다. 지연성 운동장애의 호발부위는 혀, 상지, 입술과 입 주위의 순이었다. BPRS 총점 및 소항목 척도점수와 SDS 척도점수는 지연성 운동장애의 유무에 따른 차이가 없었다. MMSE 총점 및 소항목 점수도 지연성 운동장애의 유무에 따른 차이가 없었다. 결론: 평균입원기간이 9년 이상인 만성정신분열병 환자들에게서의 지연성 운동장애의 유병율은 50.5%이었고, 연령이 가장 의미있는 위험인자임을 확인했다. 만성정신분열병 환자들이 주 대상인 본 연구에서는 지연성 운동장애와 정신분열병의 음성증상 및 인지기능 장애와의 상관성은 입증하지 못했다. Objectives: The purpose of present study was to determine the prevalence rate of tardive dyskinesia and to search for its risk factors in chronically institutionalized schizophrenic subjects. We also examined the relationship between tardive dyskinesia and both negative symptoms and cognitive impairments in the same subjects. Methods: Subjects were 271 in-patients(174 males, 97 females) at Masan Dongsuh Hospital. They met DSM-IV criteria for schizophrenia and had been taking fixed doses of antipsychotics for at least 3 months. Tardive dyskinesia was assessed by Abnormal Involuntary Movement Scale(AIMS). Cases of tardive dyskinesia were ascertained by the criteria of Schooler and Kane (1982) and DSM-IV. The rating of psychopathology was acquired using Brief Psychiatric Rating Scale(BPRS) and Schedule for the Deficit Syndrome(SDS) and the assessment of cognitive function using Mini-Mental State Examination(MMSE). Results: The prevalence of tardive dyskinesia is 50.9% and the frequency of tardive dyskinesia was high est in male above the age of fifty. But there was no statistically significant relationship between the frequency of tardive dyskinesia and both the length of hospitalization and the daily dose of antipsychotics. The frequency order of abnormal movement in the patients with tardive dyskinesia was as follows : tongue, upper extremities, lips and perioral area. We couldn't find any significant difference in the total and subscale scores of BPRS between the groups with and without tardive dyskinesia. There were no differences in MMSE scores between the groups with and without tardive dyskinesia. Conclusion: This study gave us that the prevalence of tardive dyskinesia was high in chronically institutionalized schizophrenic inpatients and that age was the most significant risk factor of tardive dyskinesia. The relationship between tardive dyskinesia and both negative symptoms and cognitive impairment, however, was not revealed.

As of 2003, construction waste has been produced at the level of 130,614.8 tons/day, in which the amount of waste concrete was 92,639.1 tons/day and accounted for about 66.4% of the amount of construction waste. Waste concrete is mainly produced in construction work and civil engineering work. Especially, road surface crushing method using a large amount of water requires thorough management of concrete wastewater. The aim of this study was to analyze water pollution due to concrete wastewater generated in repair of bridge deck using road surface crushing equipment and to suggest reasonable countermeasures for solve the problem. In this study, it was surveyed current conditions of produced concrete wastewater in bridge deck repair, analyzed physical features of concrete wastewater, expected effects of water pollution on inflow rivers if it is not treated, established treatment plan of water pollution by categories, and calculated capacity of each treatment process and required amount of necessary chemicals. As a result of sampling wastewater generated in field sites and testing it at a lab scale, it was revealed that the original wastewater was produced in removing concrete from bridge deck slabs using surface crushing equipment whose pH was 12.53, CODMn was 12.910mg/L, SS was 547.0mg/L, and other heavy metals were included in extremely small quantities.

The purpose of this study was to analyze the educated teachers' satisfaction of the in-service education programs of industrial technical and technology teachers in Chungnam National University. This study was carried out through survey to accomplish the purpose. The number of questionnaires collected was 86. This study used the SPSS program to conduct a descriptive analysis of the data. The results of this study were as follows: (1) The satisfaction about 'teachers' participation', 'utilization of audiovisual materials and instruments' and 'level of professor and lecture' was relatively high. (2) The satisfaction about 'environments of in-service education programs', 'evaluation of achievement', and 'efficacy of lectures' was relatively low.

Isolation and Identification of Fusicoccum Species from Quercus dentata

Kim, Ki Woo,Kim, Pan-Gi,Lee, Myung-Bo Korean Society of Forest Science 2007 한국산림과학회지 Vol.96 No.5

An imperfect fungus Fusiococcum species was isolated from Quercus dentata. A naturally infected Daimyo oak tree was collected and showed elongate wounds on the stem. The fungal cultures were initially white and cottony, and later turned dark gray. Numerous solitary pycnidia were developed on the medium surface, and typically spherical. Yellowish conidial masses were exuded from pycnidia on the culture plates. Conidial masses were swollen and measured as approximately 100 to $300{\mu}m$ in length. It appeared that conidia were usually held together in globose to oval drops. Conidia were hyaline, single-celled (nonseptate), ellipsoid to fusoid, and measured as approximately $8.0{\times}2.7{\mu}m$. Based on these cultural and morphological characteristics, the fungal isolate was identified as a species of Fusicoccum Corda. To preserve and examine fungal spores exuded from pycnidia on the medium surface, a vapor fixation procedure for scanning electron microscopy was employed in this study. The specimens were exposed to the vapor of 2% (v/v) glutaraldehyde and 2% (w/v) osmium tetroxide each for 2 h. With the vapor fixation we obtained excellent retention of conidial masses in this study. The simple and versatile procedure for demonstrating fungal spores and their exudation from fruiting bodies would facilitate characterization of diverse pathological and environmental isolates as they are in native environments.

<P>Cardiac magnetic resonance (CMR) imaging is widely used in various medical fields related to cardiovascular diseases. Rapid technological innovations in magnetic resonance imaging in recent times have resulted in the development of new techniques for CMR imaging. T1 and T2 image mapping sequences enable the direct quantification of T1, T2, and extracellular volume fraction (ECV) values of the myocardium, leading to the progressive integration of these sequences into routine CMR settings. Currently, T1, T2, and ECV values are being recognized as not only robust biomarkers for diagnosis of cardiomyopathies, but also predictive factors for treatment monitoring and prognosis. In this study, we have reviewed various T1 and T2 mapping sequence techniques and their clinical applications.</P>
