Obstetrics and Gynecology include gynecology which is concerned with the treatment for the disease based on physiology and pathology of women, and obstetrics which is concerned with pregnancy delivery. These obstetics and gynecology can be said to date from the birth of human beings. This paper has carried on the studies about the generating and developing process of obstetics and gynecology. The results of this study are as follows : Distinction in Northern and Southern Dynasties were much more Obstetrics and Gynecology studying the Obstetrics and Gynecology books in that time, the study about "oncosis" (腫瘤) and forms of drug, pill, powder, pIaster were carried on. The highest distinction in Sui age were research and development on pathogenesis and cause of disease about Obstetrics and Gynecology disease and it was appeared representatively in "Zhubingyuanhoulun""諸病源候論" which was special book on cause of disease and pathogenesis and syndrome, And it was explained about abnormal vaginal discharge in this book. Obstetrics and Bynecology were developed on theory and clincis in Tang age when "Taiyshu"(太醫暑) was established. "Taiyshu"(太醫暑) taked complete charge of medical operation and education, published much excellent Obstetrics and Gynecology books than the past. Among them specially "Qianjinyaofang""千金要方" explained Obstetrics and Gynecology matter first in three volumes and "Qianjinyifang""千金翼方" explained this matter first in four volumes. This point indicate that Obstetrics and Gynecology's importance was established in Tang age, so Obstetrics and Gynecology's developmental history, Song age was the acme period. "Taiyju"(太醫局) was established in "xining""熙?" 9 year and Obstetrics belonged to one of nine departments under "Taiyun"(太醫局), so Obstetrics and Gynecology was separated from the other medical parts and it was prepared of it's progressing bases independently and appeared of changes in quality and increase in quantity about theory and prescription of Obstetrics and Gynecology, specially determination of treatment based on the differentiation of symptoms and sighs was taked a serious view. Besides four great physicians in Jing and Yuan dynasies diversified Obstetrics and Gynecology contents through their only medical theory and clinical treatment.

A strain of bacterium producing antifungal antibiotic was isolated and identification of the strain was attempted. We could identify the bacterium as being a Bacillus sp., based on morphological observation, physiological characteristics, and 16S rDNA sequence analysis, thus leading us to designate the strain as Bacillus sp. AH-E-1. The strain showed potent antibiotic activity against phytopathogenic and human pathogenic fungi by inducing mycelial distortion and swelling and inhibiting spore germination. The antibiotic metabolite produced by the strain demonstrated excellent thermal and pH (2-11) stability, but was labile to autoclaving. From these results, we could find a broader antifungal activity of Bacillus genus. Isolation and characterization of the active agent produced by the strain are under progress.

The purpose of this study is to investigate the effect of organizational safety and health management activities on safety and health performance by using the results of safety activity level evaluation of public organizations. To this end, a research model was established by using three fields as independent variables among the four areas of the safety activity level evaluation index: safety and health system, safety and health activity plan, and safety and health activity level, and the safety and health activity performance field as a dependent variable. Correlation analysis and regression analysis between major variables were performed. As a result of the correlation analysis, the safety and health activity performance had a significant positive (+) correlation with all of the safety and health system, safety and health activity plan, and safety and health activity level. The safety and health system had a significant positive (+) correlation with the safety and health activity plan and safety and health activity level, and the safety and health activity plan had a significant positive (+) correlation with the safety and health activity level. And as a result of the regression analysis, it was found that the organization's safety and health system, safety and health activity plan, and safety and health activity level all had a significant positive (+) effect on safety and health activity performance.

In this paper, we examine the roles, mutual relationships, and guidelines for a healthy life as exemplified by the characters Santiago and Manolin in Ernest Hemingway's novel "The Old Man and the Sea" and use this content to compare the happy home life of elderly couples in Korea. Through a metaphorical exploration of the lives of elderly husbands and wives in Korean society, the study examines their significance as the core of the family, particularly during their senior years. Ernest Hemingway's "The Old Man and the Sea" portrays Santiago as a unique embodiment of virtue and humanity. As an elderly male fisherman, he symbolizes a profound connection with the sea, as well as qualities such as courage, patience, and unwavering passion. His story underscores the importance of pursuing new goals and maintaining hope even in old age. The relationship between Santiago and Manolin provides insights into the dynamics of elderly husbands and wives in their domestic lives. Manolin's unwavering support for Santiago and his understanding of Santiago's dreams exemplify the significance of mutual support and the establishment of common goals for elderly couples. These characters serve as exemplary models for understanding and supporting one another within a family setting. Within the context of family life, applying these exemplary models and relationship dynamics fosters mutual respect, collaboration, emotional expression, and effective communication. Supporting each other and working towards common goals can enhance the family atmosphere, resolve conflicts, and enrich domestic life. Furthermore, when elderly couples share common goals and enjoy activities together, they strengthen their bond and create a more fulfilling family life. These shared activities deepen the affection between elderly husbands and wives and contribute to a thriving household. Through the characters of Santiago and Manolin in "The Old Man and the Sea," we present in this study a deeper understanding of the values and roles within the domestic lives and affection of elderly husbands and wives. Mutual respect, collaboration, emotional expression, communication, mutual support, common goals, hope, and shared domestic activities all play pivotal roles in maintaining a healthy family life and establishing happiness and well-being within the family. We expect this study to offer valuable insights into the fields of family studies, elderly welfare, and sociology.

Objective: We have tested our hypothesis that inclusion of purified glycerol as a replacer of portions of dried distillers grain with solubles (DDGS) would affect growth performance, rumen fermentation and blood parameters, carcass and sensory traits, reducing sugar and glycogen contents, and volatile compound profiles in longissimus thoracis (LT) in Korean cattle steers. Methods: A total of 20 Korean cattle steers (27.0±0.2 months old; 647±10.5 kg body weight [BW]) were assigned to a conventional control group or a glycerol group (3.17% purified glycerol addition as a replacement for DDGS and molasses). The steers were individually allowed to receive the experimental concentrate at the daily amount of 1.5% of their individual BW and a total 1.0 of kg/d of rice straw twice daily. The feeding trial was conducted for a period of 20 weeks. Results: Glycerol supplementation (GS) increased (p = 0.001) concentrate intake. However, GS did not affect (p>0.05) average daily gain, feed efficiency, and ruminal volatile fatty acid concentrations. GS tended to increase (p≤0.10) serum glucose concentrations at the 16th and 20th weeks. GS decreased (p = 0.001) LT pH. GS did not affect (p>0.05) carcass traits and the chemical or physicochemical compositions, reducing sugar or glycogen contents, sensory traits, and most of volatile compounds in the LT. Conclusion: The inclusion of purified glycerol as a replacement for DDGS in the finishing diet did not affect growth performance, rumen fermentation parameters, and carcass quality in Korean cattle. The purified glycerol could be used as a substitute for other energy sources such as DDGS in beef cattle, depending on the price.

To characterize the food components of two mussels (wild hard-shelled mussel (HM) Mytilus coruscus, and cultured sea mussel (SM) Mytilus edulis) in Korea, we examined the proximate composition, fatty composition, amino acid/mineral content, texture, collagen content and chemical and taste compounds. Regarding the proximate composition, HM had lower moisture levels and higher crude protein and carbohydrate contents than SM. The amino nitrogen, volatile basic nitrogen and total amino acid contents of HM and SM were 250.6 and 227.3 mg/100 g, 11.2 and 12.0 mg/100 g, and 17,451.1 and 15,334.8 mg/100 g, respectively. The major amino acids were glutamic acid, aspartic acid, glycine, alanine, lysine and arginine. The major fatty acids of HM and SM were 14:0, 16:0, 16:1n-7, 20:5n-3, and 22:6n-3, which did not differ significantly between the two mussels. HM had a higher n-3 polyene ratio, and a lower saturate and monoene ratio than SM. Regarding the taste-active compounds, the free amino acid contents of HM and SM were 1,116.5 and 961.8 mg/100 g, respectively, and the major free amino acids were taurine, glutamic acid, glutamine, glycine, citrulline, lysine and arginine. The primary minerals in both HM and SM were Na, Cl, K and P which did not differ significantly between the two mussels. The soluble and insolube collagen contents of HM and SM were 265.8 and 228.4 mg/100 g, and 119.5 and 121.8 mg/100 g, respectively.
