In order to determine the distributional ecology, and to investigate factors influencing these features, the diatom communities in plankton at depths of one, twenty-five, fifty, and seventy five meters in the area were studied and measured over a fifteen month of period. Measurements of environmental factors including temperature and salinity and algal nutrients such as phosphate, silicate, nitrate, and ammonia were also made at the same depths and locations. The results indicate that the size of diatom communities and the species population changes were heavily dependent upon to season and location parameters as well as nutrient concentrations and hydrographic factors. Major factors influencing population distributions varied with principal species responsible for dominant species and species sucession. Two distinct distributional patterns in total diatom crop were observed in the study area. Maximum standing crop observed during spring and/or summer were related to the concentration of nutrients available at the onset of the spring bloom on a large scale. On a small scale, however, the distributions of total diatom standing crops were significantly correlated with both season/location factors and with hydrographic parameters as well. Vertical stratification of diatoms was observed only in the presence of the thermocline in the water column. Within the study area there was some seasonal consistancy in the composition of the species groups. However, some species association in these environments may vary with the change of season.

Jeonju is well-known as a native place of traditional Hanji from ancient times because of it's proper weather, soil, and sunlights. Traditional Hanji is selected one of the Traditional Cultural Contents Industries of Jeonju nationally, and can produce synergy effects on gaining competition if we develop traditional Hanji industry into high-technology by relating cultural contents. The purposes of this study was to identify consumer attitudes and behaviors toward traditional Hanji products. The results of this study were as followed: 1. Representative products of Jeonju City were a rice with vegetables, a traditional Hanji, and a Korean-style house, and these results showed a consistancy with Han-Brand products promoted by Ministry of Culture and Tourism. 2. Many consumers experienced of a box, a copy paper, a book or notebook made of Hanji, but less experienced of fashion accessary products. Consumers had higher interests in wall or window paper and copy paper, but had lower interests in fashion accessary products such as necktie, shawl, and folding fan. More consumers intended to use wall or window paper and copy paper, but intended fashion accessary products less. Many kinds of Hanji products were produced and displayed on a Hanji Crafts House, but only few consumers had experiences. 3. Younger generations had higher interests and experiences of Hanji products, and unmarried officiers or full-time house wives had experiences Hanji crafts more. 4. Consumers were interested in daily necessaries or interior products made of Hanji.

The aim of the present study is to research into the household work time change and its structure in urban home makers by the choosen eleven studies and KBS's Data 1981, 1983, 1985, 1987. This study were proceeded under some limitations, it is choosen eleven studies that is different region: large city, medium and small town, and the household work's categories of original auther were changed. And KBS's Data was composed of general formation without personal character of home maker: FLC, number of childeren, family type, education, region. Although this study have a certain meaning of implementation, research into the household work time change and its's structure. The major findings of this study can be autlined as follows: (1) Total household work time did'nt so much changed through the choosen eleven studies compared with the last twenty years ago. In the change of each province household work time, time connected with meals and dwelling did not showed consistancy of change. But cloth laundering and mending time of 80's were declined compared with 70's. Family care time of 80's was increased, home management and buying time was declined untill '85, but again increasing trend '87. In choosen eleven studies, the household work time structure of urban home makers can be outlined: time connected with Meals>Family care>Cloth laundering and mending>Dwelling>Home management and Buying. (2) KBS's time-series data were analized as follows: a) Total household work time of '87 was declining gradually in weekday (34 minutes), sat. (41 minutes), sun (1 house and 2 minutes) compared with '81. b) The change of each province household work time: the time of cooking and sewing home management were declining gradually in its Mean time and its ratio of acters. The acter ratio of household worker in '81, '83, '85 was composed Cooking > Cleaning > Laundering > Home management > Buying > Child care > Sewing. In '87 was composed Cooking > Cleaning > Laundering > Buying > Home management > Child care > Sewing. c) The structure of household work time revealed some differences in each year and a day of the week.

This study was done to develop a eating behavior scale for high school girls using Stunkard and Messick(1985)'s three factors(dietary restraint disinhibition, hunger) as a conceptual framework and to test the validity and reliability of the scale. The subjects were 202 high school girls. The convenience sample is consist of 96 normal weight and 106 obese girls. Data were collected between October 28 and November 25 in 1996 and analyzed using the SPSS package. The new 32-item scale measuring these factors is presented 1. Three stable factors emerged and these contributed 45.7% of the variance in the total score. All 32 items loaded above .35 on each factor, 2. Factor 1 was named disinhibition(14 items), factor 2 was named cognitive restraint of eating(10 items), factor 3 was named hunger(8 items). Comparison of factor Ⅰ, factor Ⅱ, factor Ⅲ between normal subjects and obese subjects showed that there was a significant difference in factor Ⅱ & Ⅲ, not in factor Ⅰ. 3. Cronbach's alpha coefficient for internal consistancy was .9393 for total 32 items and .8820, .8652, .8490 for three dimensions of eating behavior in high school girls. Recommendations are suggested below : 1. Replication study with appropriate age groups be done to test validity and reliability, 2. The present developed scale must be a reliable measure of eating behavior and should have utility in further study on how effective nursing intervention related to different kind of groups such as disinhibition group and cognitive restraint of eating group. 3. To extend validity of the scale, further study is needs using more larger subjects which is consists of dieters and free eaters.

Cowpea starch which is the main ingredient of Mook(Korean starch gel) was isolated from cowpea and characterized by physico-chemical methods. Gelatinization properties were investigated by using Brabender amylograph. Starch granules were oval-shape and their size range was $5\;-\;25{\mu}m$. Crystalline type observed by X-ray deffraction was C-type. Apparent amylose content was 20.7%, Amylose and amylopectin fractionated from cowpea starch appeared to have vlue value of 0.55 and 0.089, and ${\beta}-amylolysis$ limit of 79.1 and 71.9%, respectively. Brabender amylograph data showed that initial gelatinization temperature of cowpea starch was $75^{\circ}C$. Also, hot and cooled paste viscosity of 8% starch paste were higher than that of 6% paste by more than twice, breakcown value of two different concentration were almost same. However, in the gelation stage, consistancy and setback of 8% starch paste appeared more than 5 times of those of 6% paste.

This paper describes the development of Korean version of two widely used self-report measure of alexithymia-Schalling-Sifneos Personality Scale (SSPS) and Toronto Alexithymia Scale(TAS), and present the preliminary results of their reliability and validity tested to an Korean college student sample(N=206). TAS showed moderate to acceptable internal consistancy with 0.26 of mean item-total correlation and 0.754 of Cronbach's alpha coefficient, while those parameters for SSPS turned out inconsistent. However, results of test-retest reliability for both scale were excellent. Factor analysis revealed tow factors for TAS and three factors for SSPS ; the four-factor structure of TAS was quite congruent with previously known alexithymaia construct, while, again, SSPS showed intermixed factor structure. TAS scores correlated fairly well with somatization scores enough to get concurrent validity while SSPS scores did not. Overall, Korean version of TAS demonstrated well matched findings in terms of internal consistency and factorial validity with original and Spanish version of TAS. The results suggest that Korean version of TAS could be a useful and reliable tool for the measurement in Korean population.

Gel consistency data collected from various experiments in same location during 1988 to 1992 were analysed to clarify the degree of varietal and environmental variation in rice. Most of japonica and Tongil-type rice varieties were belonged to soft gel consistency, and average gel length of japonica rice was longer than that of Tongil-type varieties. Gel length of glutinous rice cultivars was extremely long, near 100mm. Year variation of gel consistency was recognized, but did not affect on varietal difference. Gel consistency of most rice varieties and pedigree lines tested varied slightly between different seeding dates or nitrogen levels, but gel length of two indica rice varieties were decreased with the later seeding dates or the higher nitrogen levels. Rice varieties belonged to extremely hard or extremely soft gel consistency showed less variation of gel length between different years, seeding dates or nitrogen levels compared with intermediate ones.

The strain A49, which produces a new type of extracellular polysaccharide was isolated from soil samples. From morphological, physiological and biochemical tests, the strain A49 was identified as a Bacillus polymyxa and named Bacillus polymyxa A49. Bacillus polymyxa A49 was found to produce a highly viscous extracellular polysaccharide when grown aerobically in a medium containing glucose as the sole source of carbon. The polysaccharide (A49 POL) showed a homogeneous pattern on gel permeation chromatography (GPC) and its molecular weight was estimated to be about 1.6 mega dalton (mDa). The FT-IR spectrum of A49-POL revealed typical characteristics of polysaccharides. As a result of investigations with HPLC and carbozole assay, A49-POL was found to consist of L-fucose, D-galactose, D-glucose, D-mannose, and D-glucuronic acid, with the molar ratio of these sugars being approximately 1:2:7:50:12. Rheological analysis of A49 POL revealed that it is pseudoplastic and has a higher apparent viscosity at dilute concentrations than does xanthan gum. The consistancy factor of A49 POL was found to be higher, and the flow index of A49 POL lower, than xanthan gum. Its apparent viscosity was comparatively unstable at various temperatures. the A49 POL showed the highest apparent viscosity at pH 3. When salts were added to A49 POL solution, the solution was compatible with up to 10% KCl, 35% NaCl, 55% $CaCl_2$, 55% $MgCl_2$, 55% $K_2HPO_4$, and 110% $Ca({NO_3})_2$, respectively.

Tomato yellow leaf curl virus (TYLCV) is a viral disease causing severe economic losses on tomato. Practical prevention of the TYLCV disease is to control tabacco whitefly (Bemisia tabaci) or to cultivate TYLCV-resistant tomato cultivars, because no agrochemical products are available to control TYLCV. In this study, TYLCV resistance of the commercial tomato cultivars were evaluated using the DNA markers tightly linked to TYLCV resistance genes Ty-1 and Ty-3 and infection with the TYLCV clones mediated by Agrobacterium. In marker genotyping, resistance alleles were detected from 4 oval type tomato cultivars (Titichal, TY tinny, TY saengsaeng II, TY sense Q). Four cheery type cultiavrs (TY endorphin, TY smartsama, Tiara TY, Olleh TY) and 6 round type cultivars (TY kingdom, TY ace, TY homerun, TY altorang, Dotaerang TY winner, Styx TY). The seedling bioassay indicated that tomato cultivars of the oval type and cherry type showed consistancy in marker genotype and phenotype while slight disease symptom was observed from some round type cultivras (TY ace, TY homerun, Styx TY) with resistance marker genotype. For fruit yields, TY tinny was greater than its control cultivar Titichal in oval types, TY smartsama was greater than its control Smile in cherry type, and TY ace and TY kingdom were greater than their control Dabok. These cutliavrs can be a good choice for high-yielding TYLCV-resistant tomato cultivars.

The purpose of this study was to examine the reliability and validity of attention deficit disorder evaluation scale-school version(ADDES-SV). Between October 1996 and November 1996, ADDES-SV was administered to 263 elementary school students in the second grade and between Jun 1996 and October 1996, 28 attention deficit hyperactivity disorder patients. In the reliability test, the test-retest reliability coefficient was significantly high and that of inattention was 0.88, that of impulsivity was 0.80, that of hyperactivity was 0.83 and total score was 0.83. In the reliability test by internal consistancy, the Cronbach $\alpha$ coefficient was significantly high and that of inattention was 0.98, that of impulsivity was 0.87, that of hyperactivity was 0.87(p<0.05). The half-sprit reliability coefficient by first-second half method showed high correlation and that of inattention was part 1: 0.96, part 2: 0.96 impulsivity was part 1: 0.95, part 2: 0.93, hyperactivity was part 1: 0.92, part 2: 0.94(p<0.05). Inter-rater reliability by pearson correlation coefficient was significantly high and that of inattention was 0.92, that of impulsivity was 0.87, that of hyperactivity was 0.89 and total score was 0.89. The concurrent validity between ADDES-SV and CAP scale was 0.85 in attention deficit hyperactivity disorder patient group and 0.79 in normal control group(p<0.05). In discriminant validity test between attention deficit hyperactivity disorder patient group and normal control group, the patient group showed higher score(p<0.05). The total discriminant capacity of the patient group in ADDES-SV was 94.6%. In this point of view, ADDES-SV scale showed high reliability and validity in applying to Korean subjects and was proved to be the useful screening test tool for attention deficit hyperactivity disorder research.
