The purpose of this paper is to investigate the phonetic characteristics of the 'focus' phrases associated with the particle '-man' in Korean. The particle '-man' is a bound morpheme which, like other postpositions such as the subject marker '-ka' and the object marker '-lil', the so-called 'case markers' in Korean, typically attaches to a noun (phrase). The semantics of '-man' roughly corresponds to that of only, its counterpart in English, and is thus classified as a 'delimiter' (Yang 1973). It is assumed in this paper that '-man', like only in English, should have a 'focus' associated with it (von Stechow 1991, Rooth 1992). In general, '-man' attached phrases get the focus, but sometimes the association is not clear-cut, especially in the cases of emphatic use of '-man' or when the context strongly favors other phrase as the focus (Choe 1996). In this paper, we compare the phonetic characteristics of the '-man' marked phrases with those to which '-ka'/'-lil' is attached, and conclude that the focused '-man' phrases show higher fundamental frequencies than their equally focused 'case' -marked counterparts. However, when the context clearly forces the focus to fall on phrases other than the '-man' or '-ka'/'-lil' attached ones, there is no meaningful difference in fundamental frequency between the '-man' and '-ka'/'-lil' attached phrases. We also compare the phonetic characteristics of the regular use of '-man' with those of the emphatic '-man'. According to our experiments, the emphatic '-man' does not bring forth its phonetic effects, namely, higher fundamental frequencies, on the' -man' attached words or phrases but rather in various other ways such as higher fundamental frequencies in '-man', lengthening of the following word-initial syllable, or the inclusion of the following word in the same accentual phrase. Finally, it is claimed that '-man' associated focus phenomena, especially the emphatic use of '-man', show some typical acoustic characteristics of the other well-known focus phenomena, namely, wh-interrogatives.

The characteristics of enzyme and gene for mannanase B had been reported from Cellulosimicrobium sp. YB-43 producing some kind of mannanase. A gene coding for the enzyme, named mannanase C (ManC), was expected to be located downstream of the manB gene. The manC gene was cloned by polymerase chain reaction and sequenced completely. From this nucleotide sequence, ManC was identified to consist of 448 amino residues and contain a carbohydrate binding domain CBM2 besides a catalytic domain, which was homologous to mannanase belonging to the glycosyl hydrolase family 5. The catalytic domain of ManC showed the highest amino acid sequence similarity of 55% with the mannanases from Streptomyces sp. SirexAA-E (55.8%; 4FK9_A) and S. thermoluteus (57.6%; BAM62868). The His-tagged ManC (HtManC) lacking N-terminal signal peptide with hexahistidine at C-terminus was produced and purified from cell extract of recombinant Escherichia coli. The purified HtManC showed maximal activity at $65^{\circ}C$ and pH 7.5, with no significant change in its activity at pH range from 7.5 to 10. HtManC showed more active on konjac and locust bean gum (LBG) than guar gum and ivory nut mannan (ivory nut). Vmax and Km values of the HtManC for LBG were 68 U/mg and 0.45 mg/ml on the optimal condition, respectively. Mannobiose and mannotriose were observed on TLC as major products resulting from the HtManC hydrolysis of mannooligosacharides. In addition, mannobiose and mannose were commonly detected as the hydrolyzed products of LBG, konjac and ivory nut.

The purpose of this study is to find out the factors that explain the sense of touch and preference of man-made leather. Date base of descriptors for man-made leather was collected by interviewing 50 consumers, 33 different kinds of commercial man-made leathers(synthetic leather and artificial leather) were assessed subjectively by 605 consumers using the 9-point scale of 34 pairs of bipolar descriptors based on the data base. Subjective ratings were analyzed by principal axis factoring with varimax rota-tion. The sense of touch of man-made leather is explained by five factors ; surface property stretchiness thickness& weight thermal property(warmth & coolness) and moisture property (sticky & clingy). The difference in the sense of touch of man-made leathers is mainly attributable to surface property and stretchiness. And the preference of man-made leathers is mainly attributable to surface property and stretchiness. And the preference of man-made leather is explained by three factors ; surface property stretchiness and quality. Higher preference is found in man-mad leather of better quality touch and softness.

Two bacterial strains producing extracellular man nanase were isolated from doenjang, a traditionally fermented soybean paste in Korea. The isolates, WL-6 and WL-11, were identified as Bacillus subtiis on the basis of their 16S rRNA gene sequences, morphological, and biochemical properties. Two genes encoding the mannanase of both B. subtilis WL-6 and B. subtilis WL-11 were each cloned into Escherichia coli, and their nucleotide sequences were determined. Both mannanase genes consisted of 1,086 nucleotides, encoding polypeptides of 362 amino acid residues. The deduced amino acid sequences of the two WL-6 and WL-11 mannanases, designated Man6 and Man11, respectively, differed from each other by eight amino acid residues, and they were highly homologous to those of mannanases belonging to the glycosyl hydrolase family 26. The 26 amino acid stretch in the N-terminus of Man6 and Man11 was a predicted signal peptide. Both Man6 and Man11 were localized at the level of 94–95% in an intracellular fraction of recombinant E. coli cells. The enzymes hydrolyzed both locust bean gum and mannooligosaccharides, including mannotriose, mannotetraose, mannopentaose, and mannohexaose, forming mannobiose and mannotriose as predominant products. The optimal reaction conditions were 55°C and pH 6.0 for Man6, and 60°C and pH 5.5 for Man11. Man11 was more stable than Man6 at high temperatures.

[ ${\alpha}$ ]Galactosidase was purified from a culture filtrate of Mortierella sp. by CM-sephadex C-50, and subsequent Sephadex G-100 column chromatography. The final preparation thus obtained showed a single band on SDS-polyacrylamide gel electrophoresis. The molecular weight was determined to be 56 kDa. $Gal^3Man^4$ ($6^3$-mono-O-${\alpha}$-D-galactopyranosyl-4-O-${\beta}$-D-mannotetraose), $Gal^{2,3}Man_5$ ($6^{2,3}$-di-O-${\alpha}$-D-galactopyranosyl-4-O-${\beta}$-D-mannopentaose), $Gal_2Man_3$ ($6^2$-mono-O-${\alpha}$-D-galactopyranosyl-4-O-${\beta}$-D-mannotriose), $Gal^2Man_6$ ($6^2$-mono-O-${\alpha}$-D-galactopyranosyl-4-O-${\beta}$-D-mannohexaose) and $Gal^2Man_5$ ($6^2$-mono-O-${\alpha}$-D-galactopyranosyl-4-O-${\beta}$-D-mannopentaose), prepared from 3 types of microbial ${\beta}$-mannnanase, were used as substrates. $Gal^3Man_4$ and $Gal^2Man_3$ had a stubbed ${\alpha}$-galactosyl residue on the $2^{nd}$ and $3^{rd}$ mannose from the reducing end of mannotetraose and mannotriose, thus ${\alpha}$-galactosidase showed a preference for stubbed ${\alpha}$-galactosyl residue. ${\alpha}$-Galactosidase hydrolyzed $Gal^3Man_4$ more rapidly than $Gal^2Man_3$. However, ${\alpha}$-galactosidase hardly acted on $Gal^{2,3}Man_5$, $Gal^2Man_6$ or $Gal^2Man_5$. The enzyme hydrolyzed melibiose to galactose and glucose, raffinose to galactose and sucrose, and also stachyose to galactose and raffinose.

The purpose of this study is to examine men's role conflicts of dual-earner family based on man's role type. Man's role type is composed of man's sex role attitude and family-role performance and categorized in four types such as traditionalism type neo-traditionalism type equalitarianism type and inconsistancy type. The test analysis can be summarized as follows; First test analysis can be summarized as follows; role performance and man's role conflict as working hours is long wife's role requirement is high family-role conflict as working hours is long wife's role requirement is high family-role is not commit man's role conflict directly affected. In addition indirect affect through family-role performance shows that man's role conflict level is low as level of income is high level of income difference between man and wife is low child is younger and intent to modern sex-role attitude. Second looking into the difference role conflict to man's role type it shows that equalita ianism type's role conflict is low and man's role conflict in traditionalism and neo-traditonalism types is high.

Man-Byeong-Hoi-Chun(萬病回春) is a representative writing of Gong Zhongxian. It was generally used by Koreans in Joseon(朝鮮) era and issued many times in the latter period of Joseon dynasty. We investigated the Jeung-Bo-Man-Byeong-Hoi-Chun (增補萬病回春, An enlarged edition of the Man-Byeong-Hoi-Chun), which is published in the 17th century, coming to a conclusion like the followings. 1. In Joseon(朝鮮), there was the J eung-Bo-Man-Byeong-Hoi-Chun which was made through revision and enlargement of the Man-Byeong-Hoi-Chun written by Gong Zhongxian of China. 2. There are two versions of the Jeung-Bo-Man-Byeong-Hoi-Chun pressed in Joseon, which are written by Kim Yuk(金堉) in 1656 and by Kim Seok-ju(金錫胄) in 1679. 3. The representative medical books of Joseon such as Eui-Rim-Chual-Yo-Sok-J ip (醫林撮要續集), Dong-Eui-Bo-Gam (東醫寶鑑), J e-Jung-Sin-Pyeon(濟衆新編) contained quotations from the J eung-Bo-Man-Byeong-Hoi-Chun(增補萬病回春), not from the Man-Byeong-Hoi-Chun (萬病回春). 4. The Jeung-Bo-Man-Byeong-Hoi-Chun(增補萬病回春) contained not only the essence of the Chinese medicine but also new medical systems reflecting actual circumstances of Joseon at that time. So, it can be recognized as the foundation of the Joseon medicine in the latter period of the dynasty.

The aim of this study is to newly interpretate to T. Hobbes' view of man and commonwealth in his On Man and On Citizen. An established reputation of the Hobbes' view is as follows. The nature of every man is egoistic. Therefor in the state of nature every man struggles against every man to acquire the good for himself. To suppress this egoistic nature of every man commonwealth established through the covenant of every man. And every man is absolutely subject to the common power of commonwealth. By doing so, every man preserves the life of himself. In that opinion, it seems that commonwealth have absolutely superiority over a man, and suppresses the liberty and autonomy of every man. This study different from that opinion speaks as follows. The nature of every man is not egoistic, but the nature of some men is egoistic. Therefor commonwealth dose not suppress the liberty and autonomy of every man, but suppress the aggression of some egoistic men through the common power. By that work, commonwealth gives every man the hope of his safety and peace. If that hope is not preserved, the duty or need that every man is subject to commonwealth will be discharged. In that state, rather the common power of commonwealth is the power of enemy, by the law of nature man struggle against commonwealth as an enemy. Therefor we can know the meaning of 'mortal god' that commonwealth is called by Hobbes.
