Essential oils of the musk from wild muskrat (Ondatra zibethicus) were analyzed by gas chromatography/mass spectrometry. Fifty-six chemical components were separated, and 14 volatile compounds (78% of composition of total essential oil) of macrocyclic musk, mainly cyclopentadecanone, 12-hydroxy-14-methyl-oxa-cyclotetradec-6-en-2-one, cycloheptadecanone and 9-cycloheptadecen-1-one, were identified by the comparison of Wiley/NBS Library from the results of GC-MS. However, l-muscone, a compound reported by earlier workers in the musk from muskrat, was not detected using the spike test in this study. Interestingly, cyclohexadecanone, which has the same molecular weight (Mw 238) as l-muscone, was identified. In addition, it is considered that because of possessing much higher amounts of macrocyclic components compared to the original musk, muskrat has higher economic values in perfume and pharmaceutical industries.
1. Objects of Research This research is purposed to find Dong-mu's thought on Pharmacology, through summarizing sentences related to pharmacology proposed in the chief writings on Sasang Constitutional Medicine. 2. Methods of Research It was researched bibliologically with Dong-mu's chief medical writings such as "Dongyi Suse Bowon Sasang Chobongyun(東醫壽世保元四象草本卷)", "Dong-mu's posthumos work(東武遺藁)", "Dongyi Suse Bowon(東醫壽世保元)". 3. Results and Conclusions 1. The grouping criteria according to the constitution proposed in "Dongyi Suse Bowon Sasang Chobongyun" is 'Spreading Outside' 'Hardening Inside' 'Cooling Organ' 'Warming Inside', but the grouping of medical herbs according to the constitution is yet not accomplished, and medical herbs is comprehended on base of effectiveness as like existing oriental medicine. 2.

The pharmacology of Sasang Constitutional Medicine is accomplished after it is modified many ti mes through clinic experience for a long time. 5. The pharmacology of Sasang Constitutional Medicine in the early period, is to comprehend herbs on the basis of how to complement 'Spreading Gathering Raising Lowering' of 'Small-Organ(偏小之臟)' according 'Qi-Mei(氣味)' and effectiveness, but that in the late period is to comprehend herbs on the basis of how to complement or to control 'Small-Organ(偏小之臟)' and 'Large Organ(偏大之臟)'.
CP (Cellular Phone) is currently one of the most attractive technologies and RT (Robot Technology) is also considered as one of the most promising next generation technology. We present a new technological concept named RCP (Robotic Cellular Phone), which combines RT and CP. RCP consists of 3 sub-modules, $RCP^{Mobility}$, $RCP^{Interaction}$, and $RCP^{Integration}$. $RCP^{Interaction}$ is the main focus of this paper. It is an interactive emotion system which provides CP with multi-emotional signal receiving functionalities. $RCP^{Interaction}$ is linked with communication functions of CP in order to interface between CP and user through a variety of emotional models. It is divided into a tactile, an olfactory and a visual mode. The tactile signal receiving module is designed by patterns and beat frequencies which are made by mechanical-vibration conversion of the musical melody, rhythm and harmony. The olfactory signal receiving module is designed by switching control of perfume-injection nozzles which are able to give the signal receiving to the CP-called user through a special kind of smell according to the CP-calling user. The visual signal receiving module is made by motion control of DC-motored wheel-based system which can inform the CP-called user of the signal receiving through a desired motion according to the CP-calling user. In this paper, a prototype system is developed for multi-emotional signal receiving modes of CP. We describe an overall structure of the system and provide experimental results of the functional modules.

Citrus junos seeds (CS) have been traditionally used for the treatment of cancer and neuralgia. They are also used to manufacture edible oil and cosmetic perfume. A large amount of CS shells without oil (CSS) are discarded after the oil in CS is used as foods or herbal remedy. To efficiently utilize CSS as a by-products, it needs to be studied through chemical analysis. Therefore, we developed an ultra-performance liquid chromatography (UPLC)-diode array detection (DAD) method for simultaneous determination and quantitative analysis of five components (two flavonoids and threes limonoids) in CSS. A Waters Acquity UPLC HSS T3 column C18 (2.1 × 100 mm, 1.8 ㎛) was used for this separation. It was maintained at 40 ℃. The mobile phase used for the analysis was distilled water and acetonitrile with gradient elution. To identify the quantity of the five components, a mass spectrometer (MS) with an electrospray ionization (ESI) source was used. The regression equation showed great linearity, with correlation coefficient ≥ 0.9912. Limits of detection (LOD) and limits of quantification (LOQ) of the five compounds were 0.09 - 0.13 and 0.26 - 0.38 ㎍/mL, respectively. Recoveries of extraction ranged from 97.45% to 101.91%. Relative standard deviation (RSD) values of intra- and inter-day precision were 0.06 - 1.15% and 0.19 - 0.25%, respectively. This UPLC-DAD method can be validated to simultaneously analyze quantities of marker flavonoids and limonoids in CSS.

This study intended to investigate the concept of Clothing Involvement and Brand and to provide useful basic data for building on affective brand strategy. The purpose of this study is as follows: first, It is to measure the result of Brand Extension attitudes and Brand Extension items by clothing involvement (high involvement/low involvement). Second, It is to classify the factors of Clothing Involvement which suggested in theoretical research and to clarify correlation between clothing involvement factor and brand evaluation, brand extension attitudes. Third, It is to investigate the affect that clothing involvement, demographic variable and brand type on Brand Extension Evaluation. Subjects of this study were the adult women in Seoul, who were extracted by sampling randomly during the fall of 1995. Questionnaire was used as major method of gathering data. They were analyzed by the SAS method such as Frequency, Anova, Duncan, Correlation, multiple regression, Factor analysis. Main result of this study were as follows : 1. In brand extension attitude evaluation by high-involve group and low-involve group, quality, reputation and buying intension of brand extension attitudes showed significant difference. B brand extension attitudes and items of high-involve group was high compare to low-involve stoup. High-involve group evaluated watch, underwear, shoes and stocking of extension items highly, and there is no involvement difference of perfume, parasol, cushion. 2. In order to classify the dimension of Clothing Involvement, it was carried out factor analysis. 1 found that Clothing Involvement was composed of 4 factors, namely, interest - fashion.perceived risk symbolism. Correlation between clothing involvement and brand extension attitude was as followed; Interest factor of clothing involvement was correlated the existing brand attitude. Brand preference of the existing brand attitude was related the image of brand extension attitude, interest of advertising was the quality and the reputation-image was the buying intension. 3. For evaluation of a factor influenced on Brand Extension, it was produced multiple -regression test. Demographic variables and brand types had some influence of Clothing Involvement and Clothing Involvement had on brand extension. 27% of interest, 26% of symbolism was explained by brand types and 15% of fashion, 6% of perceived risk was explained by brand types, demographic variables. And, 10% of brand extension was explained by interest, fashion and symbolism.
This study is to analyze the effect of product involvement on consumer purchase process. From review on previous involvement literatures, enduring product involvement can be defined as "a person's arousal and motivational state activated by product on the basis of his basic value, objective and ego-relevance." To evaluate the effect of involvement on product purchase process, 11 hyphotheses concerning behavioral aspects which is expected to comprise consumer purchase process and to be influenced by degree of involvement were constructed: prepurchase information search, alternative brand comparision, utilization of product attribute, brand differentiation, brand commitment, product knowledge, influence of reference group, dependence on price, price awareness, cognitive dissonance and purchase optimization. Hyphotheses are tested with data from 388 housewives through 20 item involvement scale developed with multi-dimensional perspective on involvement. The scale successfully provides rank order of 8 selected products expected to cover the spectrum of product involvement: formal clothes, coffee, washing machine, shampoo, perfume, detergent, soft drink, pain-reliever as the order of product involvement. Major findings of this study are as follow. First of all, incresed differences were found in hihg involvement product like formal clothes with respect to the degree of prepurchase information search, alternative brand comparision, utilization of product attribute, influence of reference group in any method of analysis. Secondly, invlovement should be interpreted as a consumer characteristic rather than a product one. This means that consumers involve themselves with products, instead products themselves do not have any involvement.
Content of crude protein in both pileus and stalk increased progresively as growth period became longer and then decreased at old stage. Contents of ash and reducing sugars followed the same trend as that of the crude protein. However, content of crude lipid decreased as growth progressed more. Seventeen kinds of amino acid were detected in Lentinula. Content of total amino acid increased as mushroom grew more, but decreased after old stage. The amino acid such as Glu, His, Gly and Ala were contained with relatively large amount in Lentinula. Content of free amino acid showed the similar trends as that of total amino acid. Contents of most of the mineral increased as growth period progressed, but K content decreased as growth period became longer. Contents of K and P were much higher than contents of other mineral. The major fatty acid contained in Lentinula were linoleicacid, palmitic acid and oleic acid. The large amount of volatile component in Lentinula was 1-octen-3-ol, so that this material was speculated to be major source of perfume. Other perfumic materials such ethyl acetate, 3-octanone, ethanol, (E)-2-octenal, 4-octen-3-one, acetaldehyde, ethyl formate were also contained in Lentinula, especially in pilous.

Various types of MOFs (metal-organic frameworks) were prepared via hydrothermal and post-grafting methods and applied as catalysts for the synthesis of jasminaldehyde, one of the representative perfume intermediates, by Aldol condensation of benzaldehyde with heptanal. Although both acid and base sites could catalyze the reaction, the catalytic performance was strongly dependent on the physical properties as well as the nature of functionalization on MOFs. While the use of sulfonated MOF catalysts led to decrease of jasminaldehyde selectivity regardless of MOFs used, the selectivity change was found to rely on the MOF types in the case of the amine-functionalization. Among the catalysts tested, MIL-101 shows the best catalytic performance, which may suggest that MIL-101 has suitable acid properties to promote the Aldol condensation and the large pore of MIL-101 is also advantageous to alleviate the diffusion problem of bulky products.
Purpose: The purpose of this study was to investigate the effect of olfactory stimulation on the balance ability of the elderly. Design: Randomized controlled trial. Methods: A total of 20 subjects were randomly assigned to the olfactory stimulation group (2 males and 8 females) and deception olfactory stimulation group (3 males and 7 females). Subjects were subjected to 30 second 3 times olfactory stimulation and deception olfactory stimulation, and the assessment measured pre and post postural distance and postural speed. Results: In the elderly, the olfactory stimulation group was significantly improved the postural distance and postural speed in the eyes closed state than the deception stimulation group (p<.05). Conclusion: As the information is provided through the olfactory stimulation, the postural distance and postural speed are significantly improved. therefore, it is expected that the olfactory stimulation in the elderly will be an effective intervention method to prevent fall.
