The study involved the measurement of flowrate and BOD in the Yeoju area and analyzed annual sewerage data by the I/I analysis technique which is common in Korea. The results of this study are as follows. The I/I for the Y-1 site before maintenance and after the completion of the whole process was reduced from 62% to 16.1% respectively with respect to maximum sewage flow per day. The average quality of water increased. The study measured the Y-2 site from a point of time corresponding to an 80% process rate and its I/I rate went up a little from 8.5% to 11.5%. At the Y-3 site, the I/I rate went up a little from 11% to 13.8%, while little change was noted in the average water quality. At the Y-4 site, the I/I rate was reduced from 43% to 16.9% and its average water quality went up. At the Y-5 site, the I/I quantity went up a little however its average water quality also went up largely. Therefore, it was concluded that the Y-5 site showed great improvement due to the sewer pipe maintenance.

Objective : The aim of this study was to evaluate Yangdorak and D.I.T.I. for analysis of Symptom-complexes. Method : This study was selected 26 acne patients in Dongshin University Oriental Medical Hospital. We used Yangdorak (SME5800N, Sord Medicom Co., Korea) and D.I.T.I. (Digital Infrared Thermal Imaging 256, Dorex Inc, Orange CA, USA) and investigated the results of Yangdorak and D.I.T.I.. We made a comparison according to Deficiency or Excess(虛實) of acne patients. Result : In comparing Yangdorak results according to Deficiency or Excess(虛實) of acne patients, Triple-energizer(三焦), Intestine(大腸), Liver(肝), Stomach(胃) meridian in Excess group are higher than Deficiency group, and Kidney(腎) meridian in Deficiency group are lower than Excess group. D.I.T.I. reveald hyperthemia of face and chest on acne patients. The temperature of face and chest on Excess group is higher than Deficiency group. There is no statistically significant value compared with data of other group.

Incentive/Disincentive (I/D) contract is designed for minimizing any disruption of traffic flow in road construction projects. I/D contracting projects have been evaluated with regard to time and cost performance in various states, more than 35 states. However, construction project managers and planners have little understanding of the project factors that affect the project time and cost performance of highway construction projects using I/D regulations. Therefore, the purpose of this research is to find factors that affect I/D project success or failure to improve the decision-making process for the implementation of I/D projects. In order to achieve the objectives of this research, the researchers collected I/D road construction project data from FDOT and performed evaluation for each collected project. Then, project data analysis to identify key factors that affect I/D project performance was performed. In conclusion, five significant factors for project time performance and six significant factors for project cost perfornace were identified and summarized.

본 연구는 세테아릴 알코올, 세틸 팔미테이트, 소르비탄 팔미테이트, 소르비탄 올리베이트, 세라마이드 등을 이용하여 제조한 액정에멀젼의 다층구조에 따른 강화된 계면막에 의해 제형의 안정성이 확보됨을 확인하였다. 편광 현미경을 통해 제형 내 몰타 크로스(maltese cross) 무늬를 확인하고, cryo-SEM을 이용하여 다층구조가 형성되었음을 확인하였다. 소각 X선 산란법(SAXS)을 이용하여 라멜라 구조 생성여부를 확인하였으며, 점도계를 이용하여 점도변화를 확인하고 정적 광 산란법(SLS)을 이용하여 입도 분포를 확인하여 액정에멀젼의 제형 안정성을 입증하였다.

In this paper, we investigate the limiting distribution of $M_n = max (X_1, X-2, \cdots, X_n)$ in the infinite moving average process ${X_t = \sum c_i Z_{t-i}}$ generated from i.i.d. negative binomial variables $Z_i$'s. While no limit result is possible, nonetheless asymptotic bounds are derived. We also present the tail behavior of $X_t$, i.e., weighted sum of i.i.d. random variables. This continues a study made by Rootzen (1986) for discrete innovation sequences.

Objectives : This study is designed to evaluate correlation between the data of D.I.T,I examination in Bell's palsy and the improving period. Methods : This study researched into the clinical statistics for 50 patients who are in Bell's palsy and they are treated with oriental medical care of Dongshin university during 18months from January 1, 2005 to June 1, 2006. The data which examinated by D.I.T.I, are the thermal difference of normal and abnormal site of acupuncture int Gl4 BL2 GB3 S3 S4 S6 TE17 in Bell's palsy. Result : There was statistic significance between thermal difference of normal, abnormal site and the improving period. The period was shorter in normal thermal pattern than hypothermal pattern, hyperthermal pattern. Conclusion : According to the result, there was a statistic significance that more thermal difference and more difficult to recover in Bell's palsy.
