This study was performed to determine the voluntary range of joint mobility for middle-aged Korean adults. One hundred and eighty-eight subjects(99 males and 89 females) at the age range of 40 to 60 participated for this study. Thirty body movements at various joints were conducted to measure the range of joint mobility. Subjects were grouped by Rohrer's into four based on 25th percentile. The data were analyzed to see the differences of range of joint mobility between sexes and Rohrer's index groups. The results of this study and previous studies were compared to see the differences of range of joint mobility due to the aging. Results of this study indicate that females are generally more flexible than males. Significant differences were found to exist in fourteen movement between sexes and in ten movements, females have larger range of joint mobility than males. There were no significant differences in range of joint mobility may have a tendency to decrease with ages. The results of this study provide important information in dynamic dimensions for middle-aged Korean and can be used to design the various and work places for the middle-aged.

This study aims to suggest the Deconstruction theory that is changing and developing by being converted into visual from as cultural code which reflects the spirit of the times and art style as well as to analyze the phenomenon of deconstruction expressed in the Fashion photographs. Fashion photographs are historical documents presenting us with the evidence of the ideal body types and culture throughout time. Fashion photographs is direct information about the fashion itself, and at the same time, it transmits various circumstances of the times. Fashion photographs has opened a new aspect called visual communication, when it's seen in new, more profound way, instead of being locked in its visible frame. Photograph is no longer a mere means to preserve documentation or pursue artistic expression. Instead, it's now regarded as a way to pursue visual transmission owing to its cognitive psychology, and this is a remarkable step toward new thing. In this study, the possible visual information function of photograph was explored from diverse aspects, such as the combination of photo and design, its linking to printing technology's mass production function, or the development of its imagery symbolism. This study shows that the nature of deconstruction can be explained as deconstruction of the sexes, deconstruction of the time and space, and deconstruction of the genre.

The accuracy of Polymerase chain reaction (PCR) assay in sexing of sheep embryos was assessed in this study. A total of 174 ovine embryos produced in vitro at different stages of development (2, 4-8 cell stages, morula and blastocyst) were sexed. The universal primers (P1-5EZ and P2-3EZ) used in this assay amplified ZFY/ZFX-specific sequences and yielded a 445 bp fragment in both sexes. Restriction enzyme analysis of ZFY/ZFX-amplified fragments with Sac I exhibited polymorphism between sexes, three and two fragments in males and in females, respectively. For verification of accuracy, blood samples of known sex were utilized as positive controls in each test. The mean percentages of sex identification by this method at 2 cell, 4-8 cell, morula and blastocyst were $73.00{\pm}5.72$, $89.77{\pm}3.79$, $3.33{\pm}8.08$ and $79.6{\pm}9.09$, espectively with the over all male to female ratio of 1:0.87. It is concluded that the ZFY/ZFX based method is highly reliable for the sexing of sheep embryos.

The personality in Marx's philosophy can be defined as an 'activity on the basis of social relations'. This concept suggests two significant implications to the difference of sexual identity between the sexes. First, according to Marx's philosophy the personality is partially influenced by the ideology. Freud's theory of Oedipus is founded on the patriarchal culture including the ideology. Freud's concept of personality ignores that aspect. That's why Freud's theory of Oedipus complex can be criticized. This is because of his ignorance of the affecting power of male chauvinism in patriarchal society. Second, more importantly and definitely, the difference of activity, especially labor, that is, male's social labor and female's private labor, has influenced the difference of the personality of both sexes.

For 8 months, from January to August, 1967, the author made a stuffy of blood total ketones and of korean cattle in different sexes and age groups in winter and summer. The results were summarized as follows : 1. The mean values of blood total ketones and acetone in Korean cattle were $2.31{\pm}0.18mg/dl$ and $0.76{\pm}0.10mg/dl$ in female and $2.35{\pm}0.19mg/dl$ and $0.74{\pm}0.12mg/dl$ in male respectively. 2. The mean values of blood total ketones and acetone during winter season were 2.39mg/dl and 0.84mg/dl in female, and 2.38mg/dl and 0.84mg/dl in male respectively. 3. No statistical significance was recognized among the sexes, the age groups and the seasons by F-distribution. 4. The mean values of blood total ketone and acetone during summer season were 2.25mg/dl and 0.67mg/dl in female, and 2.32mg/dl and 0.64mg/dl in male respectively.

With a view of to providing basic data for designing male's and female's clothes, heslthy males and females(five each) were exposed to three different environmental temperature( $20{\pm}1.0^{\circ}C$ $28{\pm}1.0^{\circ}C$,$32{\pm}1.0^{\circ}C$ in the nude. Their adaptation of skin temperature, physilogical responses, oral temperature, blood pressure, pulse rates) and psychological reactions (thermal, comfort and perceptive sweat sensations) were analyzed to be as follows; The subjects's skin temperature had a similar look of adaptation, but the stability of skin temperature differed at the $20{\pm}1.0^{\circ}C$and at the $28{\pm}1.0^{\circ}C$ Males had higher skin temperatures at three environmental temperatures, but females showed a higher temperature change at the $20{\pm}1.0^{\circ}C$ and$28{\pm}1.0^{\circ}C$ and males at the $32{\pm}1.0^{\circ}C$ Thus females were more resistant to the cold, while male were more resistant to the heat. As environmental temperature increased, oral temperature and pulse rates also grew up. Females turned higher in oral temperature and lower in blood pressure, but both sexes had a normal range of physiological reactions. Even though three environmental temperature were same changes in thermal sensation at and in perceptive sweat sensation at $28{\pm}1.0^{\circ}C$and in perceptive sweat sensation at$32{\pm}1.0^{\circ}C$ the two sexes had the same response in comfort sensation at the three environmental temperature.

Gonadal development, gametogenesis, reproductive cycle, and first sexual maturity of Reishia clavigera were investigated monthly from July 1998 to June 1999 through cytological and histological observations. R. clavigera had separate sexes, and was an internal fertilizer. The ma1e penis was located near the two tentacles. The ovary and testis were composed of a great number of oogenic lobules and spermatogenic tubules, respectively. The size of ripe oocyte ranged from 130 to 140 ${\mu}$m in diameter. The peripheral cytoplasm of the germinal vesicle of the ripe oocyte in many cases were surrounded by smaller yolk granules, while the eccentric cytoplasm was occupied with larger ones. The reproductive cycle of R. clavigera could be classified into five successive stages: early active, late active, ripe, spawning, and recovery. Spawning of females occurred from early July to August when the seawater reached above 24.8$^{\circ}C$. Spawning of males occurred from early June to August in the water above 22.8$^{\circ}C$. Minimum size for sexual maturity of both sexes was above 10.0 mm in shell height. Each egg capsule was a cylinder or spindle in shape, 4-6 mm in length and 1-2 mm in width. Colors of newly spawned egg capsules showed yellowish white or pale yellow, while those with veliger larvae showed pale black, and released larvae or dead egg capsules showed black violet. The fecundity in an egg capsule ranged from 70 to 91 eggs (mean＝80.28 eggs).

Uhwangchungsimwon(UC) is widely used as a herbal medicine on various circulatory disorders in Korea. The objective of this investigation was to characterize the acute, subacute hepatotoxic potency of orally administered UC in rats. In the acute and short-term studies, male rats of 150~170g were gavaged with 0, 7.5 g/kg once daily for up to 1, 5, 10 consecutive days. No differences in body weight, serum enzyme activities, absolute and relative liver weight and histopathological examination on liver between control and UC-fed groups were found. In the subacute study, UC was administered orally to both sexes of rats for 30 days(0, 1.875, 3.75 or 7.5 g/kg/day). There were no-doserelated hepatotoxic signs of general symptoms, body weight gain, water consumption and serum biochemical analysis. Slight decreases of food consumption observed at 3.75 and 7.5 g/kg groups of both sexes were due to be full of UC fed. Gross necropsy and histopathology revealed no evidence of hepatotoxicity related to UC. Our data indicate that hepatotoxicity was not caused by administration of UC up to 7.5 g/kg/dayfor 30 days in rats.

The hematology and clinical chemistry data based on the well defined normal data are essential in the safety assessment. It is important that normal values of cliniclal pathology parameters would be optimized to be accurate. So the purpose of this experiment was to compare the ranges of normal data in hematology value and serum chemistry between both sexes of F344 and Wistar rats at 5, 10, 20, 40 and 90 weeks. of age. The neutrophils eosinophils and monocytes increased with age in male Wistar rats. And serum total bilirubin and potassium were highest and alkaline phosphatase was lowest at 90 weeks in Wistar rats. As compared with Wistar rat the serum aspartate aminotransferase of F344 rats increased with age in both sexes but inorganic phosphorus decreased with age. The serum alkaline phosphatase decreased with age and potassium was highest at 90weeks. These normal data would be useful in improving the accuracy of clinical pathology value in the safety assessment.
