Pohang was frequent in the circulation of goods from the late Chosun period when it built its national granaries to relieve the poor in Hamgyorig province. And Pohang was a trading center of commodities in the era of Japanese empire, because of securing such facilities as railway, harbor, and roads. Meanwhile, the Japanese began to immigrate actively in the city which functioned as a port. In Pohang, most of them became merchants rather than fishers, and thus acquired commercial supremacy in the region. Pohang exported mainly grain and marine products and imported cotton stuff in the 1910's. From the 1920's, the city mostly exported grain. It collected a variety of corn from neighboring areas and exported that lively to Bosan through its improved harbor facilities and the rail line between Pohang and Cangrung. Consequently, Pohang exported its commodities to about twenty city in Japan. including Osaka, Kobe, Tokyo, and Nagoya. The port city did so. as the Japanese government wanted. It, therefore, played a faithful role as a commercial city of Japanese colony.

One-step reduction/dyeing method was applied for ramie dyeing with natural indigo powder. The effect of reduction/dyeing conditions including the pH of bath, dye temperature and time, and concentration of indigo powder and reduction agent on dye uptake and color properties were investigated. Regardless of addition of alkali, the dyed fabrics appeared in the PB Munsell color range(λmax: 660 nm) and the dye uptake was much higher with no addition of sodium hydroxide. Dyeing was carried out through the use of only sodium hydrosulfite in the bath. The maximum dye uptake was obtained at 60 for 30mm. Saturated dye uptake was obtained at 2 g/L of sodium hydrosulfite concentration up to 2 g/L of indigo powder. Whereas, at higher indigo powder concentration (4 g/L), more than 3 g/L of reducing agent concentration was required for obtaining the saturated dye uptake. Color reproducibility was reliable with color difference in the range of 0.03~0.16. Regardless of color strength, fastness to rubbing was acceptable with a 3/4~4/5. Fastness to washing, dry cleaning, and light of samples with low color strength were poor. Whereas, fastness to washing, dry cleaning, and light of samples with high color strength were very good.

As an effort to find a new scaffold for α-glucosidase inhibition, we have prepared total 11 phenylalkylated piperazine derivatives and tested their α-glucosidase inhibitory activities. Compounds 8 (IC50=2.73±0.075 mM) possessing two 3-methoxyphenethyl group on 1,4-position of piperazine showed comparable potency to acarbose used as reference. But other compounds were inactive to α-glucosidase. The result indicated that proper substituents on the piperazine can engender α-glucosidase inhibitory activities on the piperazine derivatives.

Although the success of the Papanicolaou test as a screening tool of cervical cancer is evident, there still exists $2{\sim}5%$ of discrepancy rate by both human and machine. To improve the qualilty of cervico-vaginal cytology, the authors compared cervicovaginal smear with cervical biopsy diagnoses, and analysed the causes of discrepancies. Among 30,922 cervicovaginal smears from June 1996 to April 1997 at our hospital, there were 271 cases of cervicovaginal smear with subsequent cervical punch or LEEP cone biopsies within several months. The biopsies and smears from a total of 98 discordant cases were reviewed. The discrepancy was attributed to sampling errors in 43 cases(43.9%), and to cytologic diagnosis in 49 cases(50.0%). Among these, 43 cases were interpretative errors(categories A;19, B;16 and C;8) whereas six cases were screening errors(categories B:2 and C:4). Among cervical biopsy cases, errors were present in four. As for 10% random rescreening, cytotechnologists reviewed 3,196 of 30,922 smears during the same period, There were 43 cases of screening error(categories A;27, B;16). Cytologic/histologic correlation was superior to 10% random rescreening of negative cases. The most effective method for quality improvement in cervicovaginal cytology was to implement both quality control(rescreening) and qualify assurance(cytologic/histologic correlation) programs.
