Background and Purposes: Over the past three decades, numerous studies performed in Korea have reported that job stress is a determinant risk factor for chronic diseases and work disability. Every society has its own culture and occupational climate particular to their organizations, and hence experiences different occupational stress. An occupational stress measurement tool therefore needs to be developed to estimate it objectively. The purpose of this study is to develop and standardize the Korean Occupational Stress Scale (KOSS) which is considered to be unique and specific occupational stressors in Korean employees. Subjects and Methods: Data were obtained from the National Study for Development and Standardization of Occupational Stress (NSDSOS Project: 2002-2004). A total of 12,631 employees from a nationwide sample proportional to the Korean Standard Industrial Classification and the Korean Standard Occupational Classification were administered. The KOSS was developed for 2 years (2002-2004). In the first year, we collected 255 items from the most popular job stress measurement tools such as JCQ, ERI, NIOSH and OSI, and 44 items derived from the a qualitative study (depth interview). Forty-three items of KOSS, in the second year, were retained for use in the final version of the KOSS by using Delphi and factor analysis. Items were scored using conventional 1-2-3-4 Likert scores for the response categories. Results: We developed eight subscales by using factor analysis and validation process: physical environment (3 items), job demand (8 items), insufficient job control (5 items), interpersonal conflict (4 items), job insecurity (6 items), organizational system (7 items), lack of reward (6 items), and occupational climate (4 items). Together they explained 50.0% of total variance. Internal consistency alpha scores were ranged from 0.51 to 0.82. Twenty-four items of the short form of the KOSS (KOSS-SF) were also developed to estimate job stress in the work setting. Because the levels of the subscales of occupational stress were gender dependent, gender-specific standard norms for both the 43-item full version and the 24-item short form using a quartile for the subscales of KOSS were presented. Conclusion: The results of this study suggest that KOSS might be an appropriate measurement scale to estimate occupational stress of Korean employees. Further and more detailed study needs to be conducted to improve the validity of this scale.

Characterization of ZSM-5 was carried out by means of XRD, SEM.

교원의 노동조합 설립 및 운영 등에 관한 법률과 교원노조 활동에 대한 교원의 인식 연구

정회욱,송정우 木浦大學校 敎育硏究所 2004 교육연구 Vol.16/17 No.-

이 연구는 교원의 노동조합 설립 및 운영 등에 관한 법률과 교원노조 활동에 대한 교원의 인식 연구이다. 본 연구에 따르면, 다수의 교사들은 다음과 같이 인식하고 있다. 교원들의 쟁의행위 허용 주장은 「정상적인 업무를 저해하지 않는」 집단행동 허용을 원하고 있기 때문에 법리적으로는 노조법상 쟁의행위가 아닌 국가공무원법 또는 교육공무원법상 단체행동 허용을 의미한다. 교원노조법에 단체 교섭의 대상에 대한 명문의 규정이 없으므로 인사제도, 교육정책·교육과정에 관한 사항이라고 하더라도 교원의 고용과 밀접불가분의 관계가 있는 사항은 단체교섭의 대상이 되어야 한다. 교원노조의 단체협약은 조합원에게만 적용되는 것이 협약의 본래의 성격이나 사용자가 형평성의 원리에 입각하여 임의로 비조합원에게도 적용하기 때문에 교원노조는 단체협약 체결에서 전체교사의 의견을 반드시 수렴하여야 한다. 그리고 교원노조의 가장 중요한 과제는 이념투쟁이 아니라 단체교섭을 통한 현장교육문제의 해결이라는 의견이 지배적이었다. This study has analysed the teacher's understanding of the 'Law for the Teacher's Union, activities and collective bargaining and showed their claims for the desirable activities from Korean Teachers and Educational Workers' Union. This study proposed studying assignments to achieve this kind of studying purpose as follows. First, how do the teachers think of 'Law for the Teacher's Union' and what's its problem? Second, how do the teachers think of teachers' union system and what's its improvement? The sample of this study was 342 teachers who work at an elementary, middle and high schools in Tae-baek City, Kang-won Province. Of 342 questionnaires distributed, 308 were returned (response rate was 90.1%), but of 308 questionnaires unreliable 18 were exempt from the application of these samples. This questionnaire data were composed of 32 questions. This statistical methods for data processing were frequencies analysis and Chi-sqare tests by SPSS to find a correlation between individual variation and each questions. This study was analysed as p<.05 within a significant level The conclusion that resulted from the data analysis were as follow. First, the admission of teachers' union of school unit should be decided through full discussion and profound debate, but in reality, the establishment of school unit is impossible because of conflict problems among the teachers' position Second, the permission of both a collective action and political activities of Korean Teachers and Educational Workers' Union also has to be profoundly discussed because it can be different from teachers' position, their career, or a member of union whether or not. If it is permissible, its permission should only be approved within its limit without a bad influence on study right and teaching-learning, therefore such results are undesirable. Third, according to the law now in force, agenda of collective bargaining is subjected to restriction in elevation of economical and social position of teacher. In spite of being an educational policy now, however, it is necessary for the teachers to expand that as the agenda of collective bargaining as to employment. The dual collective bargaining system of KTEU(Korean Teachers and Educational Workers' Union) and KFTA(Korean Federation of Teachers' Associations) can have an effect of checks and balances. Fourth, a member of union has to act within the limit of the law and manager should reciprocally endeavor to form democratical administration because a conflict between manager and a member of union in school causes a schism between two parts. Finally, collective agreement between the superintendent of education and teachers' union should be entered into an agreement through procedures of collecting sufficient public opinion. the problem which confronts teachers' union should try to find a solution to the problem without being split in teachers' profession. Moreover teachers' union should be in search of a better solution. It is necessary for pressure group, and to act through playing careful attention to the tends of public opinion and policy-making.

토양으로부터 분리한 Bacillus sp. YJ-63으로부터 항진균성 항생물질을 분리하여 그 구조를 분석한 결과는 다음과 같다. 항생물질은 7개의 α-amino acid와 1개의 β-amino acid가 결합한 환상구조를 가지는 iturin E 계에 속하며 특히, β-amino acid의 methylene 수가 기존의 iturin E 보다 더 많은 것으로 나타났다. Structural analysis was performed by the ^1H-NMR, ^13C-NMR, amino acid composition analysis and FAB-mass. The instrumental analysis represented that the potential antifungal antibiotic belonged to the iturin E group antibiotic, consisting of 7 α-amino acid residues and a collection of β-amino acid with aliphatic side chain. Compared to the iturin E group, notably, the potent antifungal antibiotic from bacillus sp. YJ-63 carried longer β-amino acid side chain. In conclusion, these findings identified a potential antibiotic, which contained a stable cyclopeptide structure with long β-amino acid side chain.

A 14-year-old male pomeranian was present with swollen left ear. The swelling occurred from base to apex of pinna. Otitis externa persisted for two years. Hematological and serum biochemistry values were not remarkable. The surgery treatment was the most appropriate method among indwelling drain, surgical, and steroid treatment in the aural hematoma because the dog was very sensitive to touching pinna and the size of aural hematoma. Longitudinal incision was applied after general anesthesia. Cefovecin was injected to prevent secondary infection. The outcome of surgery was good. There was no evidence of recurrence for one year.

KIOM-MA128 is a novel oriental herbal medicine which is for atopic dermatitis and asthma. The purpose of this study was to develop on analytical method of arctiin in rat plasma after oral administration of KIOM-MA128. Analyte was separated on a Atlantis dC18 reverse phase column, using gradient mobile phase (A:B = acetonitrile: 0.1% formic acid in water) at a flow rate of 0.3 mL/min. Detection was performed by electrospray positive ionization mass spectrometry using multiple reaction monitoring of the transitions of arctiin at m/z 552.4 → 372.8 and internal standard (carbamazepine) at m/z 237.0 → 194.5. The limit of quantification was 1 ng/mL for arctiin. The precisions were lower than 15% and the accuracy was between – 12.21 and 3.2%. The maximum concentration found in plasma samples was 4.1 ng/mL. The present method was successfully developed for detecting arctiin in plasma and this results would be utilized to the further study.

Silicon-to-silicon anodic bonding was accomplished using lithium doped interlayer. Lithium doped interlayers were deposited on silicon substrates by electron beam evaporation, which has a fast deposition rate compared with sputtering method. Silicon-to-silicon bonding occurs in the range of temperatures from 250℃ to 300℃ with the applied voltages from 70V_(DC) to 100V_(DC). The bonding strength obtained from tensile test was about 5MPa under the condition of 80V_(DC) in 300℃. The surface morphology of lithium doped interlayer was studied with the atomic force microscopy (AFM). Finally, secondary ion mass spectroscopy (SIMS) analysis was carried out in order to investigate the role of the lithium ions in bonding mechanism.

In this paper, a new type of wavelength converter using XPM within a loop-mirror is proposed and demonstrated. The proposed structure decreases hardware components for implementation of XPM wavelength converter and makes it possible to get non-inverted and inverted output signals simultaneously. Also, we generate wideband pumping mode series for FWM wavelength conversion scheme and propose the effective filtering method for selecting converted wavelength from FWM outputs. The results show that the pumping mode range is over 30nm within 5dB power fluctuation, and that a pumping and a prove wave can be removed successfully by using both of Michelson interferometer and polarization controller.
