The purpose of this paper was to find out obese women's respective characteristics of torso body shape. The subjects were 132 obese women for direct measurement and were 101 obese women for indirect measurement, age of 20~59. The criterial of obesity base on Rohrer index($\geq$1.6) and busts girth ($\leq$90). The results were as follows : 1) In comparison with the average body shapes in common body types, in 30's was bigger in the bust and waist girth than the different age groups. 2) According to the difference in the basic girth(bust and waist girth, hip and bust girth, hip and waist girth) the body types were classified 2 groups. Types 1 was large bust and slightly curved from waist to hip. Type 2 was large hip and larger in the curve from waist to hip than type 1.

Present review is built on base of research work on Ganoderma lucidum in our laboratory. A great deal of experimental evidence has suggested that the pharmacological activities of Ganoderma lucidum (Lingzhi) are related to anti-oxidative and free radical scavenging activity. The anti-oxidative and free radical scavenging effects of polysaccharides and triterpenoids isolated from Ganoderma lucidum in different oxidative injury models including tert-butylhydroperoxide (tBOOH)- damaged mice peritoneal macrophages, alloxan-induced diabetes, experimental liver injury models induced by carbon tetrachloride (CCl4), D-galactosamine (DGal) and Bacillus Calmette-Guerin (BCG) plus lipopolysaccharides (LPS) were investigated. It is also demonstrated that Lugu lingzhi, one of Ganoderma product, significantly inhibited LDL oxidation mediated by endothelial cells and decreased monocyte adhesion to endothelial cell (EC) induced by Oxidative low-density lipoprotein (ox-LDL) and advanced glycation endproducts (AGE). Lugulingzhi-treated serum could markedly inhibit the expression of intercellular cell adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-l) induced by ox-LDL and AGE.

The Daehwa and Donsan tungsten-molybdenum deposits are composed of numerous fissure-filling veins developed in Precambrian gneiss and Cretaceous granite and quartz porphyry. K-Ar age of biotite in granite and that of muscovite in ore veins are $105{\pm}5\;Ma$ and 88.2~88.6 Ma respectively. Occurrence of ore deposits shows that relevant igneous rock is possibly quartz porphyry rather than above mentioned granite in temporal view point. Vein structure and mineralogy suggest that ore veins were formed by continuous vein filling, not by repeated mineralization. Three distinct depositional stages with decreasing age can be devided on the basis of mineral paragenesis and fluid inclusion studies: Stage I, deposition of oxides and silicates; stage II, deposition of base-metal sulfides and sulfosalts with carbonates; stage III, deposition of barren calcite and fluorite. Tungsten, molybdenum and tin mineralization occurred in stage I.

The author conducted an experiment using P-A Cephalography of 242 male and female subjects of ages ranging 2-6, 7-15, and adult group. By means of Nakago's method of measurement, the standard value of Korean was obtained. The results were as follows; 1. In the group of an age, the male value was greater slightly than female value. 2. In each age group the difference between the right and left widths could be recognizable, however, it was not much great. 3. In each group, regardless of sex, the growth relation was clearly distinguishable at PO, ARI, ARE, MG, AG, and CAW. 4. When the standard value of adult Korean was compared with that of Japanese, Japanese was great with respect to the width of maxillary portion and Korean was great with respect to the width of mandibular portion. 5. Maximum head width of white man was almost similar to that of Korean, however, maxillary alveolar base width of white man was considerably small or the dental arch was narrow.

With their complex structure that includes a thin disc, spiral arms, and often a bar, galaxies have been regarded as something beyond the human perceptions. Hence, the studies on galaxy formation in the 20th century have almost exclusively based on schematic scenarios. With markedly improved knowledge on cosmology over the last couple of decades, we have finally acquired a base from which galaxy formation can be studied from the first principles of physics. I review the modern history of the study of galaxy formation and present some preliminary results from the most recent numerical simulations that provide more realistic pictures of galaxy formation than was available ever before. In terms of galaxy formation, the age of scenarios is fading away, while the age of physical understanding is rising over the horizon.

Objective: The objective of the study is to analyze adult men's somatotype characteristics, age range from 20s to 50s comparing the direct anthropometric measurement values and to provide the basis information for developing clothing patterns. Background: The comparative study among the age groups is very fundamental to understand the body characteristics of each subjects group. Therefore, comparison of body measurements in age groups was applied in this study. Method: The anthropometric data from the $5^{th}$ Anthropometry of Size Korea(2004) and $6^{th}$ Anthropometry of Size Korea(2010) were applied for the data analysis. Results: As a result, the chest depth/chest width index(the value of chest depth divided by chest width) was increased and the waist depth/waist width index was decreased in all age groups. In addition, the hip depth/hip width index was decreased in age of 20's and 50's. This means that the chest width and hip width were decreased and the waist width were increased. From the data of the 5th Size Korea, the obese men(BMI: 25~30) in the 50s showed the highest percentage of 47.1%, and 44.8% of obese men(BMI: 25~30) in the 40s recorded the highest rate base on the data of the 6th Size Korea. Conclusion: It is concluded that the some differences were showed between the 5th anthropometric data and the 6th data. In particular, obesity tendencies of men in their 20's and 30's were observed significantly compared to other age groups. Application: These findings from the study can be utilized men's wear design and construction that reflect body characteristics.

The purpose of this study was to analyze the dietary habits and food intake by age, based on the nutrition counseling data of medical health examination. The subjects were 5,511 adults(3,139 males and 2,372 females) who took comprehensive medical test in Gyeonggi area, and they were evaluated from January 1, 2007 to December 31, 2007. Survey samples were divided by age groups : 30>, 30~39, 40~49, 50~59, 60~69, 70{$\leq}$ years. The subjects were composed of 57% male and 43% female. The results showed that the dietary habits of ${\geq}$50 group were relatively good. On the other hand, in 30> yrs group had more dietary habit problems, they had irregular meals and the ratio of skipping breakfast was high. And they frequently had meals out. regularity of meals, eating breakfast was higher in ${\geq}$70 yrs groups than in other groups(p<0.001). frequency of overeating was higher in 30>, 30~39${\geq}$yrs groups than in other groups(p<0.001) and speed of eating meal were fast in 50~59 yrs groups than in other groups(p<0.01). For foods with high cholesterol and fat, it was shown that the older the subject, the fewer the frequency of consumption(p<0.001). For kimchi and salty foods, food intake showed a negative relationship with age(p<0.001), whereas for fresh vegetables and high-calcium fish, it showed a positive relationship(p<0.001). All in all, it was shown that as the people get older, their dietary habits tend to get more appropriate. In conclusion nutrition education based on their dietary habit by age should be taught, so that people have a healthy dietary habit and food intake for the rest of their life.

This study was conducted in order to obtain the information of the histological changes in each of six segments of the epididymal ducts in Korean native goats. Thirty-two Korean native male goats were examined, dividing into seven groups, at 4 weeks intervals from 8 to 32 weeks of age. The results obtained were as follows. 1. The epididymal ducts showed histologically an abrupt growth at the age of 16 weeks being followed by almost full maturation at the age of 24 weeks. Diameter of the cauda was steadily larger than that of the caput and corpus of the epididymal ducts. 2. Spermatozoa in the lumen of epididymal ducts were first observable at the age of 16 weeks, thereafter showing sparse in the lumen of caput, whereas most dense in the lumen of cauda in the density of spermatozoa. 3. Ducts in the caput and corpus were lined by ciliated columnar epithelium until the age of 12 weeks, and later by pseudostratified ciliated columnar epithelium which was composed of ciliated columnar cells, clear cells and basal cells. Ducts of cauda epididymis were lined by simple ciliated columnar epithelia until 12 weeks of age and later by simple or pseudostratified ciliated columnar epithelium, and two types of ducts (small ducts with high epithelium and large ducts with lower epithelium) were noted. Nucleus of the epithelial cells in the caput were located in the base of cells but in the corpus and cauda, those were located in the mid part of cells. cilia were most developed in the epithelia of the corpus.

This study tries to analyze topographic distribution and characteristics of as well as formative age and incision rate of fluvial terraces in Danyang River on western side and Geum River on eastern side of the northern Sobaek Mountains and to estimate geomorphic development during the late Quaternary in the mountains regarded as one of the uplift axes in the Korean Peninsula. OSL age dating shows that the fluvial terrace I with an altitude above riverbed of approximately 7~13 m in Danyang River has a formative age of approximately 18 ka (MIS 2) and incision rate in the river is approximately 0.156~0.194 m/ka based on the age. Altitudes above riverbed of the fluvial terrace I in Geum River range from approximately 7 to 14 m and the terrace is thought to be older than 70 ka based on age result from aeolian sediments above the terrace deposits, suggestive of an incision rate less than approximately 0.10 m/ka. These results indicate lower uplift rate in the northern Sobaek Mountains than in the Taebaek Mountains. Moreover, it can be suggested that the northern Sobaek Mountains has experienced asymmetric uplift during the late Quaternary, because the river on western side of the northern Sobaek Mountains shows greater uplift rate than the eastern side river does. Low incision rate in Geum River can be attributed to low altitude of the river basin with little difference in altitude from the base level as well as to gentle river slope due to influence of Nakdong River.
