The effect of crosslinking on hand of the cellulase treated Tencel fabrics was investigated. Tencel fabrics were crosslinked with DMDHEU, mechanically prefibrillated, hydrolyzed by cellulase, and treated with softener. The treated fabrics were characterized by add-on, weight loss, DP rating, WRA, strength, SEM analysis and hand measurement. As DMDHEU concentration increased, weight loss of DMDHEU/cellulase treated fabrics decreased. However, cellulase treatment decreased DP properties and strength retention. Less fibrils were observed in the cellulase treated fabrics after DMDHEU treatment than the cellulase treated ones. It was confirmed that crosslinking with DMDHEU treatment was effective to control fibrillation. At 5% of DMDHEU concentration, DMDHEU/cellulase treated fabrics showed softer, smoother and bulkier hand compared with other treated fabrics. Among mechanical properties, bending and shearing properties were decreased progressively through DMDHEU, cellulase, and softener treatment. DMDHEU treatment contributed to impart resilience, cellulase treatment to bulkiness and softener treatment to smoothness. As the treatment of DMDHEU, cellulase, and softener progressed NUMREI, FUKURAMI, and THV increased with the exception of KOSHI.

The optical lightcurves of flare events can be regarded as a direct indicator about the existence of magnetic activity in low-mass stars. Stellar flares are generated by magnetodynamic processes in the stellar interiors as on the Sun and indicate that the locally intensified active regions still exist on the photosphere. However previous photometric observations are limited to a few selected active objects because of their faintness and randomness of the flare occurrence. Based on dedicated deep (r~23), long-term (24 night) time-series monitoring of the open cluster M37 from MMT 6.5m transit survey program, we searched for flare-like transient phenomena in the 3,052 M-dwarf lightcurves with relatively high-temporal resolution (30s-90s). In order to collect all statistical significant events, we applied the change-point analysis with filtering algorithm using local statistics. We found a number of flares from 412 M-dwarf stars that are probable cluster members. Nearly half of them have periodic brightness variations with a near or distorted sinusoidal shape. With a small exception of binary cases, most of these variations appear to reflect the presence of large starspots resulting in rotational brightness modulations. We will discuss the relationship among magnetic activity indicators and dependence on spectral type.

The core idea of the critical regionalism could be summarized as a self-conscious synthesis between universal civilization and world culture. After World War II, it has been applied to architecture for overcoming the problem of Industrial Capitalism and uniformity of 20th century Modern Architecture. Naturally, religious architecture cannot also be an exception in this cultural trend, thus we can also apply the critical regionalism to the Korean Catholic Church Architecture with the basic premise that the Traditional Western and Modern Style Church Architecture should be regarded as universal civilization, and the Traditional Korean Architecture and endemicity as one of world culture. In the context, this article attempts to analyze the regionality of Korean Modern Catholic Church Architecture constructed between the 19th century and 1980's, and how it has been differently transformed with the view of the critical regionalism. Its analysis will be carried out within three types; transformation of the Traditional Korean Architecture and the influence of Japanese Modern Architecture, representation of the Traditional Korean Architecture, and abstraction of the Traditional Korean Architecture with each advantages and disadvantages.

This paper is to analyze the legality in which the fraud rule allow the issuer of L/C or a court to disrupt the payment to the beneficiary under the deferred payment credit when the nominated bank for deferred payment undertaking made prepayment or negotiation before the maturity date and fraud is identified to be involved. Since the function of commercial L/C is to provide absolute assurance of payment to a beneficiary, the fraud rule based on fraud exception has been known as the negative factor which lead to the disruption of "principle of independence & abstraction" under the commercial L/C transactions. As a result, the fraud rule is necessary to limit the activities of fraudsters, but its scope must be carefully circumscribed so as not to deny commercial utility to an instrument that exists to serve as an assurance of payment. But the fraud itself has not been firmly established because it is inherently pliable in its concept. There are numerous contents to describe the application of fraud to the L/C transactions as a standard such as egregious fraud, intentional fraud, L/C fraud(omitted here), flexible fraud, and constructive fraud. And so the standard applicable to the commercial transaction as the fraud rule would be high or low depending upon the various standards of fraud.

Peroxisomes play an important role in cellular defense systems and generate secondary messengers for cellular communication. Saccharomyces cerevisiae containing oleate-induced peroxisomes were subjected to buffer-soluble extraction and two chromatographic procedures, and a protein with antifungal activity was isolated. The results of MALDI-TOF analysis identified the isolated protein as peroxisomal 3-ketoacyl-CoA thiolase (ScFox3). Purified yeast ScFox3 exhibited thiolase activity that catalyzed the thiolytic cleavage of 3-ketoacyl-CoA to acetyl-CoA and acyl-CoA. ScFox3 protein inhibited various pathogenic fungal strains, with the exception of Aspergillus flavus. Using ScFox3-GFP and PTS2 signal-truncated ScFox3M-GFP, we showed that only ScFox3-GFP, with an intact PTS2 peroxisome signal sequence, was able to translocate into peroxisomes. Yeast ScFox3 is a natural antifungal agent found in peroxisomes.

Substance P (SP) is known to be expressed in the nerve fibers of dental pulp and periodontal tissues. It was recently reported that SP expression increased in response to orthodontic force. In the present study, we investigated the effect of SP on expression of mineralization markers and heme oxygenase-1 (HO-1) in human immortalized periodontal ligament (IPDL) cells. Cell viability was measured using a 3,4,5-dimethylthiazol-2-yl-2,5-diphenyl tetrazolium bromide (MTT) assay. The expression of mineralization markers, including alkaline phosphatase (ALP), osteonectin (ON) and bone sialoprotein (BSP), and heme oxygenase-1 (HO-1) was assessed by reverse transcription-polymerase chain reaction (RT-PCR) and Western blot analysis. SP did not significantly change human IPDL cell viability, with the exception of the 24 hour treatment group. Treatment of human IPDL cells with $10^{-10}$ to $10^{-4}M$ SP upregulated mineralization marker and HO-1 expression in a time- and concentration-dependent manner. Our results suggest that SP may modulate osteoblastic cell differentiation of human IPDL cells through a mechanism involving HO-1 expression.

This paper attempts to account for the recent decline in the share of 'regular employees' among total employees. It finds, among other things, that the decline which began in 1993 is not associated with the changes in the composition of the worker groups that have differing tendency to work as regular employees. Overall, the decline in the share of regular employment is mainly due to the workers' increased transition probability out of 'regular employment', with the exception of the younger workers for whom the decrease in the rate of entry into 'regular employment' has also been an important reason of such a decline.

This study empirically analyzed how the organizational fairness perceived by revenue officers affect the empowerment and employee efforts. The result of the analysis revealed that as for job fairness, distribution fairness and interaction fairness, with the exception of process fairness, have significant influence on the empowerment while the empowerment, in turn, has significant influence on the employee efforts. This finding confirms that a high level of organizational fairness perceived by revenue officers in their job processes results in a high level of empowerment, which then produces heightened employee efforts, eventually contributing to the efficiency of revenue officers' job performance and the improvement of satisfaction with service quality. Therefore, it is necessary that administrators of revenue offices allow their subordinates to develop their potentials by empowering the employees and delegating authority.

This study was carried out to investigate the important factors relating to runoff and pollutant loads in a plot unit located in an agricultural area. Of the precipitation parameters, such as total precipitation, days since last rainfall (ADD, the rainfall was more than 10mm) and average rainfall intensity on runoff, the strongest effect was obtained due to total precipitation, but the rainfall intensity showed a slightly positive correlation. It was expected that both variables, i.e. total precipitation and rainfall intensity, would lead to the generation of greater runoff. In contrast, runoff was negatively correlated with ADD, which is understandable because more infiltration and less runoff would be expected after a long dry period. The TSS load varied greatly, between 75.6 and $5.18{\times}10^4g$, per event. With the exception of TN, the TSS, BOD, COD and TP loads were affected by runoff. The correlations of these items were proportional to the runoff volume, with correlation coefficients (r) greater than 0.70, which are suitable for use as NPS model data. The TSS load showed very good relationships with organics (BOD & COD) and nutrients (TN & TP), with correlation coefficients greater than 0.79. Therefore, the removal of TSS is a promising factor for protecting water basins.

Anaerobic bacteria are the major residents of human skin and mucous membrane. The importance, as opportunistic pathogens, of anaerobic bacteria are well recognized because of more population. with decreased defense against bacterial invasion due to chemotherapy, rediation therapy, extensive surgical operation etc. are dealt at hospitals. An analysis of the anaerobe isolation results at Yonsei University Medical Center during the January 1974-May 1975 period was made and the following results were obtained. 1) From 118 patients 146 strains of anaerobes were isolated. Among these 81.3% were nonsporforming anaerobes. Most frequently isolated anaerobes were Pc. asaccharolyticus, Ps. anaerobius, Ps. intermedius, B. fragilis and Cl. perfringens. 2) Anaerobes were frequently isolated from wound, female genital, intraabdominal, and pleuropulmonary specimens. Fewer anaerobes were isolated from blood, spinal fluid and liver specimens. 3) The ratio of anaerobe isolation to total bacteria isolation were; liver 66.7%, intraabdominal 33.3%, pleuropulmonary 28.9%, spinal fluid 5.0% and blood 4.2%. 4) Among the 118 anaerobe isolated patients, 48.3% yielded anaerobes only and rest of them yielded anaerobes together with aerobes. 5) Most of the gram-positive anaerobes were susceptible to the antibiotics tested. Exception was to tetracycline to which appreciable number showed resistance. It was noteworthy that only 48% of B. fragilis was susceptible to tetracycline.
