In order to understand the precipitation acidity and chemical composition of ion species in Iksan area as well as to know the difference of chemical characteristics in precipitation samples from the viewpoint of precipitation sampling method, precipitation samples were collected by wet-only automatic precipitation sampler and hulk manual precipitation sampler in Iksan, from March 2003 to August 2003. The mean pH of precipitation was 5.0. There was a little significant difference in the mean value of pH between automatic and manual sampler. However, pH values of some precipitation samples were lower in automatic sampler than in manual sampler, especially in case of precipitation samples with small rainfall for March 2003. The mean concentrations of each ions in precipitation were generally a little higher in precipitation samples collected by the manual sampler than in those collected by the automatic sampler because of accumulation of dry deposition on the surface of glass funnel installed at the manual sampler during the sampling period of no rainfall. Dominant species determining the acidity of precipitation, were NH₄+ and nss-Ca^(2+) for cations and nss-SO₄^(2-) and NO₃- for anions. The mean concentration of NH₄+ and nss-Ca^(2+)j were 31 μeq/L and 9 μeq/L for the automatic sampler and 40 μeq/L and 16 μeq/L for the manual sampler, respectively. In addition, nss-SO₄^(2-) and NO₃- were 27 μeq/L and 13 μeq/L for the automatic sampler and 32 μeq/L and 17 μeq/L for the manual sampler, respectively. Although the concentrations of the acidifying ions of nss-SO₄^(2-) and NO₃- were about 3 times higher than those for foreign pristine sites, precipitation acidity were estimated to be natural due to the neutralization reaction of the alkaline species of NH₄+ and nss-Ca^(2+) with its higher concentrations. Considering the ratios of nss-SO₄^(2-)/NO₃- and NH₄+/nss-SO₄^(2-), it was found that ammonium sulphate was dominant in Iksan precipitation. The major non-sea salt ions were maximum concentrations for March, but decreased with increasing of precipitation amount.

This study was undertaken in an attempt to explore nursing student health behaviors. Based on responses from 218 2nd grade nursing students in nursing college in the City of Incheon health behaviors were evaluated. Data were collected from 19th of August to 5th of September in 1998. The open ended questionnaire which was used in study formulated based on literature review and contained health concept, personal habits, exercise, cause of the stress and stress management. The results of the analysis were as follows ; 1. The nursing student thought health as an adaptation mostly. 2. 1.8% of the student smoked the cigarettes. 3. 78.0% of the student drinked the alcohol. Most of them began to drink by peer pressure. 4. 97.2% of the student consumed caffeine-containing products. But most of them don't consumed much. 5. 36.7% of the student took the drugs. Most of the drugs were analgesics & vitamins. 6. 39.4% of the student exercised regularly. Most of the type of the exercise were physical exercise and walking. 7. Most of the causes of the stress were the burden of the school works. Most of the stress management were sleeping.

In one bath dyeing system of silk/acrylonitrile(acryl) fabric with acid/disperse dyes and acid/cation dyes, adsorption behavior of acid dyes, disperse dyes and cation dyes on silk and acryl fabrics were examined. In the dyeing of acryl with the C. I. Disperse Red 19(Red 19) and The C. I. Disperse Red 60(Red 60), dye uptake with Red 19 was higher than that with Red 60. When the silk and acryl fabric were dyed with C. I. Basic Red 27(Red 27), dye uptake on the acryl was higher than that on the silk. When the silk/acryl fabric was dyed with Red 19 and Basic 27, solid shade could be obtained with Red 19 but could not be obtained with Basic 27. In the dyeing of silk/acryl fabric dyed with Blue 80/Red 27 and C. I. Acid Blue 113(Blue 113)/C. I. Basic Blue 116(Blue 116), compatibility could be obtained with Blue 80/Red 27 but that could not be obtained with Blue 113/Blue 116.

In one bath dyeing system of silk/cellulose triacetate(triactate) fiber blend fabric with acid/disperse dyes, adsorption behvior of acid dyes and disperse dyes on silk and triactate fabrics were examined. In the dyeing of triactate with the C.I. Disperse Red 19(Red 19) and the C.I. Disperse Red 60(Red 60) at 100℃, dye uptake with the Red 19 was higher than that with the Red 60. When the silk/triaceetate was dyed with Red 19 and the Red 60 at 100℃, dye uptake on triacetate was influenced by affinity of the dye to the silk fabric dyed together. In the treatment of the silk fabric dyed with the Red 19 and Red 60 in desorption bath with and without undyed triacetate, desorption of the dyes from the silk fabric was influenced by the affinity of the dyes to the triacetate. When the silk/triacetate was dyed with the Blue 80/Red 19 and Red 60 at 100℃, color of triacetate dyed with the Red 19 and Red 60 was not influenced by the Blue 80 but silk dyed with the Blue 80 was influenced by the Red 19.

This paper concerns with the utilization of the treatment of sulfuric acid for improvement of dyeing of poly ethylene terephthalate(P. E. T) fiber. The P. E. T. fiber drafted to various times was treated with 70~74% sulfuric acid at 80~95℃ for 30~120min and neutralized with 2% ammonia. The fiber thus prepared has remarkable advantage in high yields of colours when dyed with C. I. Basic Green 4. The tensile strength of 3.2 times drafted P. E. T. fiber is as high as that of used fiber.

This paper is an attempt to survey and analyze copper contents in the sea-water of downstream of the GumRiver which empties into the Yellow sea holding contaminated water from the mining and metallic industries. To survey and analyze it, eight different areas of sea-water of the Gum River was picked up from the upper surfaces and the lower stratum at each full and ebb tides on April 20, 1978. Then careful examination in to the copper contents was made and the following results were obtained : 1. The sea-water of examining area of the downst rcam of the Gum River holds 0.048-0.141 parts per million (PPM) of copper contents, and the average is around 0.079 (PPM) 2. Copper contents at each full and ebb tides made some differences respectively. At ebb) tide copper contents (0.095) is rather heavier than that (0.063) at the full tide. It indicated that the sea-water comprised much copper contents. 3. It has been examined that the lower stratum (0.092) contains more copper contents than in the upper surface of the sea-water (0.067). 4. The result obtained after the examination by each area indicated that around Jang Hang Refinery, 1st area, the copper contents is heaviest (0.125) and the mouth of downstream of the Gum River, 3rd area, revealed the least amount (0.046) of copper contents. 5. Since the turbidity at the downstream of the Gum River is thick when seen through the naked eyes, the contamination seems to be serious, but it is thought that the pollution of the Gum River is not still sorious in terms of the quantity of copper, on of heavy metal, contained.

In order to study about the basic productivities on the estuary of the Kum River, first, I conducted several experiments on the tidal variation on the site encircled on Fig. 1. I measured PH, water temperature, outside temper ature, chloronity, nutrient salts. PH variation range was 7. 20-7. 95, water tempreature increased with outside one, chloronity varied from 1.0 to 13‰, NO2-N increase is proportional to part of fresh water flowed into the estuary and their range is 0.28-0.15㎍-aton/L. P04-P content increase is reversely proportional to fresh water content In general nutrient salts showed more higher value with water temperature increase. The results in detail of this experiment are shown up at Table 1, 2.
