To determine the effects of exercise program which is developed to advanced the physical fitness of the old aged, mountain climbing exercise for 12 weeks was performed to the agee 60's. Studied subjects consisted with 50 na: and 50 women, aged 60's, who resided in Taejon city and had not done regular exercise. Body fat, muscle strength, body flexibility and cardiovascular endurance of them were calculated and compared before and after mountain climbing exercise for 12 weeks from September 1, 1996. Following results were obtained therefrom; Body fat reduced $2.57\%$ in made, and $2.68\%$ in female, but muscle strength was improved 3.07kg in made and 2.43kg in female. Body flexibility, tested by bend forward, was improved 2.17cm in made, and 2.32cm in female. Cardiovascular endurance, tested by 1,200m running time, was reduced 18.2 seconds in made and 15.5seconds in female. For the conclusion, there showed advancement of physical fitness after the 12 weeks mountain climbing exercise.

Fungal isolates belong to Fusarium solani (perfect stage : Nectria haematococca) were isolated form pea, ginseng roots and soybean during 1995 and 1996 in Korea. Thirty-five isolates were identified as F. solani f. sp. pisi based on the morphological characteristics and their pathogenicity. Microconidia formed on the long conidiophore were ovoid or oblong sizing 5~14 x 2.5~5.0 $\mu\textrm{m}$. Macroconidia were formed on carnation leaf agar media with 4.8~5.3 x 32.0~40.7 $\mu\textrm{m}$ in size. They belonged to $\beta$-type since their 3-septate macroconidia were smaller than $5\mu\textrm{m}$ in width. Chlamydospores were smooth- or rough- walled and formed in terminal or lateral branches of hyphae, intercalary, or in chains. Most isolates were highly virulent to pea seedlings, producing dark brown or rot lesions. This is the first report of f. solani f. sp. pisi being pathogenic to pea in Korea.

Hypersensitive cell death of plants during incompatible plant-pathogen interactions is one of the efficient defense mechanisms of plants against pathogen infections. For better understanding of the molecular mechanisms involved in the plant hypersensitive response (HR), TMV-induced biotic plant cell death and CuSO4-induced abiotic plant cell death were compared in terms of expression patterns of ten different defense-related genes as molecular markers. The genes include five pathogenesis-related protein genes, two plant secondary metabolite-associated genes, two oxidative stress-related genes and one wound-inducible gene isolated from tobacco. Northern blot analyses revealed that a same set of defense-related genes was induced during both biotic and abiotic cell death but with different time and magnitude. The expression of defense-related genes in tobacco plants was temporarily coincided with the time of cell death. However, when suspension cell cultures was used to monitor the expression of defense-related genes, different patterns of the gene expression were detected. This result implies that three are common and, in addition, also different branches of signaling pathways leading to the induced expression of defense-related genes in tobacco during the pathogen- and heavy metal-induced cell death.

Pervaporation has become important as a method to separate liquid mixtures, sepecially azeotropic and close boiling-point mixtures. Especially, water-alcohol separations have been carried out a lot because of the practical interests in the industries. However, outstanding membranes with high selectivity and high permeability have not been available in common use yet. In order to separate selectively out the water mixed with alcohols with an aim of the purification of the alcohols, a membrane has tO have excellent affinity to water. Among the hydrophilic polymers, polyacrylic acid and poly(vinyl alcohol) are used widely. In recent years, ionomers and polyion complexes, better hydrophitic materials, start to be used. The polyion complex membranes, consisting of polyacrylic acid (PAA) and polycation, showed excellent permeation rates and selectivities. It was known that among the polycations, ioneries, which have quaternary ammonium groups in the backbone chain, were more effective in giving membranes of higher permselectivities. On this base, syntheses and characterizations of the polycations, with different chemical structures from the published ones, for the polyion complex membrane formation were studied in this paper.

To investigate the cognition of labeling system and its problems, problems in laundry, and consumer's dissatisfaction and to decrease problems in management of clothing products, total 476 subjects were surveyed in Taejon. The major results were as follows ; 1. The cognition of labeling system was understood by 93.1% of respondents, and 72.9% of them prefer to recognized labeling by figures and letters than by either of them. Most of respondents got the knowledge of labeling system from school. The most frequently experienced mislabeling was the label for management. 2. In cleaning, 60.4% of respondents made their decisions of the laundry method after seeing labeling system. When the label recommanded either of hand washing or dry cleaning, they usually laundered with hand washing after a few times of dry cleaning. The first consideration factor for laundry was fiber composition of textiles. 3. About 70% of respondents understood ironing, laundry, and drying mark on labeling system, and 53.8% understood fiber composition and bleaching. 4. More than 90% of respondents experienced dissatisfaction in handling clothing products. The reason of dissatisfaction was deformation and decoloring after laundry. Most of respondents experienced change of tactile sensation, too.

To evaluate the antitumor activity and antimetastatic effects of Kamicheungyeolhaedog tang(KCHT), studies were done experimentally. The results were obtained as follows: 1. KCHT extracts exhibited a significant cytotoxicity against A549, SK-MEL-2, SK-OV-3, and B16-BL6 cell lines. 2. KCHT extracts showed significant inhibitoty effect on DNA topoisomerase I 3. The T/C% was 145.8% in KCHT treated group in S-180 bearing ICR mice. 4. KCHT extracts exhibited efficient affect adhesive effect of A549, B16-BL6 cell to complex extracellular matrix. 5. In vitro neovascularization assays, angiogenesis was insignificantly inhibited in KCHT treated group as compared with control group. These results suggested that KCHT extracts might be usefully applied for prevention and treatement of cancer.

The maltose binding protein (MBP) fusion protein system is a versatile tool to express and isolate recombinant proteins in E. coli. In this system, MBP fusion proteins are efficiently isolated from whole cell lysate using amylose conjugated agarose beads and then eluted by competition with free maltose. Since MBP is a rather large molecule (∼42 kDa), for further experiments, the MBP part is usually proteolytically cleaved from the fusion protein and subsequently removed by ion-exchange chromatography or rebinding to amylose columns after washing out excess and MBP-bound maltose. In the present study, we have developed an improved method for the removal of cleaved MBP, which is advantageous over conventional methods. In this method, factor Xa cleaved MBP fusion proteins were incubated with Sepharose beads conjugated with MBP specific monoclonal antibodies and then precipitated buy centrifugation, resulting in highly purified proteins in the supernatant.

This paper presents the 3-D profile measurement system of live human faces, which was developed specially for 'KUMDORI sculptor robot' of the '93 Taejon Exposition. '93 Taejon EXPO. The basic principle for measurement adopts the slit beam projection which is a method of measuring 3-D surface profiles using geometric optics between the slit beam and the CCD camera. Since the slit beam projection consumes long measuring time, it is unfit to measure the 3-D profiles of living objects as human. Therefore, the projection type slit beam method which consumes short measuring time is newly suggested. And an algorithm to reconstruct the 3-D profile from the deformed images using finite approximated calibration is suggested and practically implemented. The projection type slit beam method was applied to spectators in a period of '93 Taejon EXPO. The measurement results show that the technique is suitable for 3-D face profile measurement on a living body.
