The suggested method of previous Son's study dichotomized subjective response data to modeling noise exposure-response. The method used maximum liklihood estimation instead of least square estimation and the noise exposure-response curve of the study was logistic regression analysis result. The method was originated to modeling community response rate such as %HA or %A. It can be useful when the subjective response was investigated based on predicted noise level. It is difficult to measure the single source emitting noise such as railway because various traffic noise sources combined in our life. The suggested method was adopted to model in this study and railway noise-exposure response curves were modeled because the noise level of this area was predicted data. The data of this study was used by previous Ko's paper but he dealt the area as combined noise area and divided the data by dominant noise source. But this study used all data of this area because the annoyance response to railway noise was higher than other noise according to the result of correlation analysis. The trend of the %HA and %A prediction model to train noise of this study is almost same as the model based on measured noise of previous Lim's study although the investigated areas and methods were different.

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.

손한일,경진범 한양대학교 이학기술연구소 2003 이학기술연구지 Vol.6 No.-

Acetone 용매 내에서 p-nitrophenyl chloroformate의 가에탄올 분해반응의 속도를 25.0℃에서 적정법에 의해 측정하였다. 측정된 반응속도상수로부터 초기에탄올 농도에 대한 실험적 2차 속도상수, k_(2)를 플로트한 결과 직선성이 좋음을 알 수 있었다. 이렇게 얻어진 속도론적 데이터로부터 p-nitrophenyl chloroformate의 속도식은 d[HCI]/ dt=k_(2)[p-NPC][EtOH]+ k_(3)[p-NPC][EtOH]^(2)임을 알았다. 그리고 활성화 엔탈피,ΔH^(≠)와 활성화 엔트로피, ΔS^(≠)를 구하였다. 이상의 결과로 acetone 용매 내에서 p-nitrophenyl chloroformate와 ethanol의 반응은 전체 반응에 대해 2차 반응과 3차 반응의 혼합 경쟁 반응인 이분자 첨가-제거 반응 메카니즘으로 진행됨을 알 수 있었다. The rates of ethanolysis of p-nitrophenyl chlorofonnate in acetone were measured using the titration method at 25.0℃ From these rate constants, plots of the experimental second-order rate constant, k_(2)^(≠) against the initial ethanol concentration were linear. From the kinetics data obtained, p-nitrophenyl chlorofonnate was found to be represented by d[HCI]/dt = k_(2)[p-NPC][EtOH] + k_(3) [p-NPC][EtOH]^(2). The values of activation enthalpy and entropy for the ethanolyses of p-nitrophenyl chlorofonnate was determined from the rate constants measured at various temperatures.? From these results, the reaction of these substrates with ethanol in acetone was mixed second-and third-order reaction for over-all reaction. and it could be estimated that this reaction has bimolecular addition-elimination mechanism.

We studied the characteristics of the recovery process where the coccoid (Viable but non-culturable, VBNC) form Campylobacter jejuni which was inactivated under aerobic condition with lower temperature (4 and 25 C jejuni ATCC 43429 strain did not recovered from VBNC form to active spiral form at 4 and 25, whereas C jejuni ATCC 33291 strain recoveredfro VBNC form at 25 Morphology and the fatty acid pattern of cell membrane of VBNC C. jejuni ATCC 33291 and ATCC 43429 were analyzed. The morphological differences between two C jejuni strains were verified using flow cytometry. C16 0(palmiticacid) and C19 0(cyclic fatty acid) showed decrease in the fatty acid composition of C. jejuni ATCC 33291 On the other hand, C19 0 in the fatty acid composition of C jejuni ATCC 43429 was increased and C14:1(myristoleic acid) was found only in C jejuni ATCC 43429 The differences in the fatty acid composition of C jejuni could be possibly related with the recovery of VBNC form C jejuni
