This study initiated with the intention to reveal the social consultations and fissures through a comparative analysis on generational characteristics by indicating occupation-related identities with the concept of social identity supported by theoretical resources. According to the three dimensions of social identity which are evaluation, potency and activity, there was more generational agreement rather than difference toward occupation-related identities. Among the 44 identities, only evaluation dimensions on minister, congressman, plane captain, farmer and potency dimensions on CEO of a major companies, professor, medical doctor, nurse, celebrity, shaman, unemployed person were statistically significant. For 'Leader and Professional', the respondents in their 50's gave high scores in both evaluation and potency dimensions. On the other side, the 30's had negative viewpoints while the 20's and 40's had neutral perspectives. For the potency dimension, the age groups were divided into the 20's, 30's and 40's, 50's; having the younger generations underestimate the potency dimension of such categories. Also for the 'General Occupation', 20's and the 30's relatively devaluated with more distinctive degree toward evaluation dimensions. For religion, 20's and 30's were positive toward buddhist monks while the 40's and 50's were more favorable with priests. For the non-economically active population, the lifetime cycle influenced each generations. When performing a two dimensional analysis toward the 'Leader and Professional' with evaluation and potency on each axis, the 50's highly evaluated both evaluation and potency dimension of such identities. However, for the 40's, 30's and 20's, the average value fell while the focus of the distribution deepened. The 30's had negative perspective toward the evaluation dimension while the 20's reflected critical attitude toward the potency dimension.

In this study, foot shapes were compared between the men in their 20's and 60's, with the application of 3-dimensional measurement data, and the classification was established in consideration of each of their features. The results are as follows: 1. The investigation into the differences between the groups for the 3-dimensional measurement items of the men in their 20's and 60's indicated that those in their 20's had larger values than those in the 60's age group for all of the length items, while those in the 60's age group had larger values for all of the angle items. 2. The analysis of the constituting factors for the feet of those in their 60's and 20's resulted in the 7 items for the 20's age group and 8 items for those in the 60's age group. 3. The comparison of foot classifications for the 60's age group and 20's age group presented 3 types each for both groups, but the features of each type was different. To examine each characteristic by each type and age group, following can be determined of the 60's age group. Type 1 had a thick instep, high malleolus position and heel and a thick formed ankle. Type 2 the entire foot was small, and the big toe was formed in such a way that it tened to bend toward the inside. When the whole size compared with similar Type 1, Type 3 had a low instep, a low heel, the big toe did not bend and ankle form was thin. The following can be determined of the 20's age group. Type 1 had narrow width a thin ankle and the big toe was formed in such a way that it bended toward the inside. Compared with length, Type 2 had wide width and a thick ankle. Type 3 had a larger overall size, thick instep and wide and the toe was big, but the characteristic of inside and outside of a malleolus position was low and the big toe's form showed no tendencies to bend.

A cDNA clone encoding the ribosomal protein S20 has been isolated from the Schizosaccharomyces pombe cDNA library by colony hybridization. The insert contained in the original plasmid pYJ10 was transferred intro shuttle vector pRS316 generate plasmid pYJll. The dDNA insert of plasmid pYJll, contains 484 nucleotides and encodes a protein of 118 amino acids with a calculated mass of 13,544 daltons. The deduced amino acid sequence of S. pombe ribosomal protein S20 is very homologous with fruit fly, rat, and budding yeast counterparts. It is also homologous with Xenopus S22 ribosomal protein. S. pombe ribosomal protein S20 appears to be relatively hydruphobic except the C-terminal region. The 728 bp upstream region of the S20 gene was amplified from chromosomal DNA and transferred into the BamHI/EcoRI site of the promoterles $\beta$-galactosidase gene of the vector YEp357R, which resulted in fusion plasmid pYS20. The synthesis of $\beta$-galactosidase from the fusion plasmid appeared to be the highest in the mid-exponential phase. The S. pombe cells with the fusion plasmid grown at 35$\^{C}$ gave lower $\beta$-galactosidase activity than the cells grown at 30$\^{C}$. Computer analysis showed the consensus sequence CAGTCACA in the upstream regions of various ribosomal protein genes in S. pombe, which would be involved in the coordinated expression of small ribosomal proteins.

The main objectives of this study were to (1) examine and compare the importance of store attributes, store commitment, store attitude, and revisit intention concerning Korean mass cosmetic brand stores between female teenage consumers and those in 20's, and (2) investigate and compare the two groups in terms of the influences of five store commitment factors on store attitude and revisit intention. On-line surveys were conducted by the marketing research company, and a total of 354 questionnaires were used in the final analysis. The results showed several significant differences between the female consumer groups in 10's and 20's. The teenage respondents placed greater importance on all store attributes except price and sales, and showed higher commitment in terms of affective commitment, and normative commitment factors than the respondents in 20's. For the teenage respondents, all four commitment factors except the normative commitment significantly influenced their store attitude and revisit intention, while the affective commitment factor did not have significant influence on either store attitude and revisit intention for the group in 20's. Normative commitment factor also did not have significant influence on revisit intention of the group in 20's. For both age groups, the negative affects of the forced commitment on store attitude and revisit intention were found.

Following ginsenoside-Rb1-hydrolyzing assay, strictly anaerobic bacteria were isolated from human feces and identified as Prevotella oris. The bacteria hydrolyzed ginsenoside Rb1 and Rd to $20-O-{\beta}-D-glucopyranosyl-20(S)-protopanaxadiol$ (I), ginsenoside Rb2 to $20-O-[{\alpha}-L-arabinofuranosyl (1{\rightarrow}6)-{\beta}-D-glucopyranosyl] - 20(S)-protopanaxadiol$ (ll) and ginsenoside Rc to $20-O-[{\alpha}-L-arabinofuranosyl (1{\rightarrow} 6){\beta}-D-g1ucopyranosyl]-20(S)-protopanaxadiol$ (III) like fecal microflora, but did not attack ginsenoside Re nor Rgl (Protopanaxatriol-type). Pharmacokinetic studies of ginseng saponins was also performed using specific pathogen free rats and demonstrated that the intestinal bacterial metabolites I-111, 20(S)- protopanaxatriol(IV) and 20(S)-protopanaxadiol(V) were absorbed from the intestines to $blood(0.4-5.1\;{\mu}g/ml)$ after oral administration with total saponin(1 g/kg/day).

In recent years, tyrosine kinases (TKs) have been the target to combat cancers, and most of the developed inhibitors are of synthetic origin. Natural compounds that have the properties as the TK's inhibitors are very limited. This paper described the isolation of a new dammarane triterpene from the tree bark of Sandoricum koetjape, along with three known related dammaranes from the damar resin of Shorea javanica, as well as their inhibitory properties against eight receptor TKs (RTKs: EGFR, HER2, HER4, IGF1R, InsR, KDR, PDGFRα, and PDGFRβ). Based on the NMR and mass spectral data the new compound was identified as (12β,20S)-12,20-dihydroxy-3,4-seco-dammaran-4,24-dien-3-oic acid (12β-hydroxydammarenolic acid) (1), while the three known compounds were identified as (20S)-20-hydroxy-3,4-seco-dammaran-4,24-dien-3-oic acid (dammarenolic acid) (2), (3β,20S)-3,20-dihydroxydammaran-24-ene (3), and (20S)-3-oxo-20-hydroxydammaran-24-ene (4). The tyrosine kinase assay of the four compounds resulted only 1 and 2 at concentration of 10 μM that had weak activity against EGFR and InsR, with their % inhibitory were 30%, 27% (1), 45%, and 32% (2), respectively. The results suggested that the presence of a linear carboxylic acid group in both compounds could be of significance to the inhibitory properties against the two RTKs.

This study aimed to investigate whether women's wear brands' sizing systems for pants item are reflecting body size and shape of their target age customers. This study classified 17 women's wear brands into three target age groups (20-30s, 30-40s, and 40-50s) and surveyed their body sizing systems of pants item. Distribution of waist circumference and hip circumference of brands' sizing systems were compared with size distribution of women in the 7th Size Korea data. The sizing systems of brands targeting 20-30s covered 28.3% and those of brands targeting 40-50s covered 27.3%, while those of brands targeting 30-40s covers 46.6%. Regarding the body types, 80% of 20-30s target brands reflected normal type which is the average body type. However, all 40-50s target brands reflected normal type while 57.8% of women aged 40-50s had large waist shape. The 30-40s target brands reflected body types the best among target age groups since the body shape distribution of the brands was similar to that of 30-40 year old woman in Size Korea. For each age group, 6 sizes with 25.2~27.8% coverage rates were proposed. The 70-91, 73-91, 73-94 sizes were overlapped between the 20-30s and the 30-40s groups. The 76-91, 76-94, 79-94 sizes were overlapped between the 30-40s and 40-50s groups. Pants size has been found to increase in waist circumference compared to hip circumference as age increased.

Commercial white and red ginseng concentrates were analysed for total ginsenoside contents, and compositions of ginsenosides $Rb_1,\;Rb_2,\;Rc,\;Re,\;Rf,\;Rg_1,\;20(S)\;Rg_3,\;20(S)\;Rh_1,\;and\;20(R)\;Rh_1$. The content of crude saponin and total ginsenosides of white ginseng concentrates (WGC) were about 2-3 times higher than those of red ginseng concentrates (RGC). HPLC showed that each ginsenoside content was higher in WGC, with those of $Rb_1,\;Rg_1,\;and\;Rb_2$ being over three times higher than that of RGC. 20(S)- and 20(R)-ginsenoside $Rg_3$, specific artifacts found only in red ginseng, were detected both in WGC and RGC by HPLC. differences in the contents of these specific ginsenosides between WGC and RGC were not significant. The contents of 20(S)-ginsenoside $Rg_1$, determined by HPLC were 0.40 and 0.53 in WGC, whereas 0.48% and 0.47%, and those of 20(R)-ginsenoside $Rg_3$, were 0.14 and 0.22% in WGC, and 0.10 and 0.11% in RGC using the methods of shibata and food Code, respectively.
