  • A novel branched wax has been developed for the control of the hardness of oil-wax gels. Using this wax, glossier application and smoother texture but tough lipstick can be obtained. Oil-wax gels are oily solids composed of liquid and crystalline solid oils (waxes). They are widely used in various cosmetic products, especially lipsticks. The control of gel hardness is one of the most important techniques in improvement of the lipstick quality. Addition of small amounts of commercial branched paraffin wax (e.g. microcrystalline wax, b-PW) to n-paraffin wax (n-PW) has been commonly used to increase gel hardness. However, gel hardness is very sensitive to the quantity of b-PW and the gel obtained is not always hard enough for practical use. In this study we examined the relationship between the gel hardness and the properties of the wax crystal in the gel. We have found that, when b-PW is added to n-PW, the wax crystal size becomes smaller (hardening the gels) and its crystallinity is decreased (softening the gels) simultaneously. Considering this result, we have developed a novel branched wax, Bis(polyethylenyl)- tetramethyldisiloxane (named ESE). ESE molecules are composed of a central tetramethyldisiloxane unit (branch unit) with polyethylene units at both ends. The central unit may suppress crystal growth while the ends are expected to prevent a decrease in wax crystallinity during crystallization. When ESE is added to n-PW, the wax crystal obtained becomes smaller without decreasing in crystallinity; consequently, the gel hardness is dramatically increased. By using ESE, the total amount of wax in a lipstick can be decreased by 30% without spoiling the stick toughness, thereby achieving glossy application and smooth texture.

  • Objectives : Methods to evaluate obesity are growing to be important in studying links between health and disease. Physicians are using BMI (body mass index) to evaluate obesity, but they can't know how much fat the body has by using that method. Even though there are several assessments, there are different scales, so patients are diagnosed as obese, by some but not by others. These studies are limited in evaluating obesity; it is necessary to study based on new knowledge. According to Oriental Medical Theory, obese people are categorized into 3 types, Fei, Kao and Liu Ren. They have different pathology and body shapes than non-obese people. The relationship between Oriental Medical Theory and BMI and assessment of body fat is a fundamental need to easily approach and treat obesity. Methods : At 00 Oriental Medical Center, 145 female subjects who intended to lose weight were given physical tests and grouped into 5 types of obesity. The physical tests were height measurement, BMI, body composition (body fat mass and lean body mass), skin elasticity and physical strength tests. One-way analysis of variance was done to compare the means of physical tests between the five types of obese women. There was some relationship between characteristics of the five types based on physical tests and Fei, Kao and Liu Ren based on Oriental Medical Theory. Least significant difference (LSD) was used in multiple comparisons. Results : 1. According to the skin elasticity test, obesity type 5 placed between obesity types 3 and 4 and obesity types 1 and 2. Obesity types 3 and 4 were in the low skin elasticity result group; obesity types 1 and 2 were in the high ones (p<0.1).Based on Oriental Medical Theory, Fei Ren and Kao Ren can be distinguished by skin elasticity degree. This result should form the basis of obesity diagnosis. 2. According to Oriental Medical Theory, Fei Ren is smaller than others. Based on height measurement, obesity types 3 and 4 were significantly lower than other obesity types (p<0.1), so there is a relationship between Fei Ren and obesity types 3 & 4. 3. There were significant differences between obesity type 2 and obesity type 4 in the body fat mass result (p<0.1). This study did not have large enough a sample size to distinguish Liu Ren. Conclusions : Further clinical research is necessary to study measurement methods of body shape type and skin elasticity for distinguishing Fei Ren from Kao Ren. The diagnosis and treatment based on the relationship of these types should be studied further.

  • Peking Opera, one of a representative Chinese dramas, is a synthesis of drama and stage art. Peking Opera's stage costume was set up in Qing dynasty though its style was embellished with mainly Ming dynasty's clothing style. The special patterns in the clothing were very important because they classified social rankings. There are two kinds of roles in Peking Opera. Sheng stands for male roles and Dan stands for female roles though Dan had traditionally been acted by male actors with female attire until the ruling of the People's Republic of China. There are five different kinds Peking Opera's stage costume. First, Mang is a formal dress for kings and generals. It is a very delicate long Po with special patterns. It has several names depending on the color and shape of a dragon. Second, Pee is a casual attire for kings, government officials, and their families. It is also a long Po with front opening and symmetrical neckline. Third, Kao is an armor of warrior which is made not for protection in a real war but for ornament of a formal dress. Kao reflects the wearer's authority when the wearer stays still, but it is a comfortable clothing for big dancing moves once the wearer starts dancing. The wearer puts a banner into the shoulder to alarm tension of a war. Fourth, Cheup is an outfit that one wears the left part adjust to the top. There are different lengths of Cheup and it has a straight neckline. There are twenty-one different kinds of Cheup according to its shape and color. Last, Yi is name for the rest of Peking Opera's stage costume other than Mang, Pee, Kao, and Cheup.

  • We determined the precise three dimensional WGS84 Coordinates and the sea level height of Seoul Radio Astronomy Observatory (SRAO). In this study, we performed the simultaneous GPS observations at SRAO and Seoul GPS Reference Station(SGRS) of Korea Astronomy Observatory(KAO) for 3.5 hours from 17KST on October 27, 1999. We employed two different antennas, i.e., chokering antenna at SGRS of KAO and L1/L2 compact with groundplane antenna at SRAO. But we employed same type of receivers, i.e., Trimble 4000SSI at both observing places. The observed data were processed by GPSURVEY 2.30 software of Trimble with L1/L2 ION Free technique and broadcasting ephemeris of GPS Satellites because of very short baseline between SGRS of KAO and SRAO. We determined WGS84 latitude, longitude, height and the sea level height of SRAO with $37^{\circ}\;27'\;15.'\;6846N\pm0.'\;0004,\;126^{\circ}\;57'\;19.'\;0727E\pm0.'\;0002,\;204.89m\pm0.02m,\;181.38m\pm0.17m$, respectively.

  • The purpose of this research is to find out how the Chinese Bronze Epigraphy has developed and how it has influenced the Chinese Academic field. The Chinese Bronze Epigraphy started from the Han dynasty, however it didn't reach the professional academic stage. After the Song Dynasty it started to be studied in full scale. Therefore, it is reasonable to see that the start of the study of bronze was from the Song dynasty. In the Qing Dynasty, the study in Epigraphy was extended on again. ShuoWenJieZi that was written by XuShen in the Han Dynasty. KaoGuTuShiWen that was written by $L{\check{u}}DaLin$ in the Song Dynasty. ShuoWenGuZhouBu that was written by WuDaCheng in the Qing Dynasty. JinWenBian that was written by RongGeng in the Republican era. This thesis examines the contents of ShuoWenGuZhouBu and JinWenBian and then synthetically compares and analyzes them. The conclusion of this study is as follows. It cannot be denied that ShuoWenJieZi and KaoGuTuShiWen significantly affected the birth of ShuoWenGuZhouBu and JinWenBian.
