Hanwoo cattle are an important food source in Korea and their supply can have a major impact on meat availability for Korean consumers. The Hanwoo population was 1.8 million head in 2005 and gradually increased to 2.6 million in 2015. Per capita beef consumption has also increased, to 11.6 kg per year in 2015, and is expected to continue to increase. Because intramuscular fat percentage is a critical contributor to meat quality, Hanwoo cattle are fed a high-energy corn-based diet for long fattening periods. Long fed diet causes significant alterations in fat percentage in the loin muscle and other areas of the carcass. However, these long feeding periods increase feeding costs and beef prices. Recently, there has been increased Korean consumer demand for lean beef which has less fat, but is tender and priced more reasonably. These consumer demands on the Korean beef industry are driving differing beef production systems and also changes to the beef grading methodology. Korean government has made a significant investment to select bulls with favorable production traits using progeny testing. Progeny tested bull semen has been disseminated to all Hanwoo farmers. A beef traceability system has been employed for all cattle breeds in Korea since 2009. Hanwoo cattle are ear-marked with a 12-digit identification number from birth to slaughter. This number allows traceability of the management history of individual cattle, and also provides information to consumers. Traceability including management information such as herd, farm, year of birth, and carcass data can determine estimated breeding values of Hanwoo. For a sustainable Hanwoo industry, research scientists in Korea have attempted to develop feeds for efficient fattening periods and precision feeding systems based on genetic information for Hanwoo cattle. These initiatives aim to Korean consumer demands for beef and provide more precision management in beef production in Korea.

The purpose of the study is to get some pieces of prior information to eventually develop competitive swimming suit designs with Korean traditional images. The study has been accomplished in following steps. First, as theoretical research, the history of swimming suit design and the requirements in designing competitive swimming suits were studied. Second, as practical research, at first, the trend of the competitive swimming suit designs in the national swimming suit market was examined. And then. the questionnaire surveys of both professional and amateur swimmers about their design preferences with purchasing and fabric-related tendencies were conducted for understanding professionals' characters more exactly. This data were analyzed through cross-analysis and multi-response analysis and x 2 was used. The results of this study can be summarized as follows : First, athletes' preferential design tendency for the swimming suit designs were examined in the aspects of style, color, pattern, logo, and accessary. In style, female athletes preferred an athletic one-piece style and male ones preferred a brief style. In color. neutral, mostly black was preferred most and cold color group like dark blue and navy blue next, regardless of sex. In addition, they preferred similar color coordination. In pattern, though solid fabrics were mostly preferred in both sexes, especially Taeguk motive were considered the most appropriate pattern to show Korean image. Besides, logo was considered importantly, and swimming caps and goggles of accessaries were generally used. Second, athletes' swimming suit purchasing tendency was as a following. the number of swimming suits possessed was more than 4 pieces. the durable period was less than 3 months. and the most important point considered in purchasing was an easy fitting for men and a design with an easy fitting for women. And most of swimming athletes preferred foreign products than domestic ones, which was attributed to excellent quality, easy fitting, and good design. and so on. Third, in fabric-related tendency, food touch, easy fitting. and opaqueness were considered importantly. and durability to chlorine, elasticity, color fastness, easy draining, lightness, and so on were demanded forward.

In Korea, It was natural and inevitable to reclaim tidal land for farming due to over-population in small territory. Looking back upon the history of tidal land reclamation in Korea, We can find the first case of it in 13th century KangHwaDo(Island), and also find several records of small scale reclamations of western sea-coast from Korea dynasty to Chosun dynasty. A lot of wide fertile agricultural areas on western sea-coast have been developed through tidal land reclamation for about 1000-year after Korea dynasty. and on these areas, we have produced rice which we live on. An average areas of farming land per capital in korea is only 0.04ha, which is one sixth of global average. For water resources, similarly, capacity of water resources alloted to one person is $11{\%}$ of global average. So, without supplementary water development, we will have suffered from a severe deficiency of water Therefore we must prepare for these predictable short water and food problems. and tidal land reclamation may be suitable alternative to settle these problems. However, tidal land reclamation is a work of closing estuary, intercepting sea water inflow, developing a freshened estuary lake and farming lands etc. therefore it apparently causes a change of ecosystem, water quality and littoral environment. Nowadays, widely recognized the importance of environmental preservation, it is desirable or requested to make phil-environmental and sustainable development minimizing the environmental influence due to tidal land reclamation project. In this paper, the role of tidal land reclamation project in the development process of Korean agriculture was reviewed and the direction of afterwards tidal land reclamation project was suggested.

Investigations into the development of new therapeutic agents for lung inflammatory disorders have led to the discovery of plant-based alternatives. The rhizomes of Anemarrhena asphodeloides have a long history of use against lung inflammatory disorders in traditional herbal medicine. However, the therapeutic potential of this plant material in animal models of lung inflammation has yet to be evaluated. In the present study, we prepared the alcoholic extract and derived the saponin-enriched fraction from the rhizomes of A. asphodeloides and isolated timosaponin A-III, a major constituent. Lung inflammation was induced by intranasal administration of lipopolysaccharide (LPS) to mice, representing an animal model of acute lung injury (ALI). The alcoholic extract (50-200 mg/kg) inhibited the development of ALI. Especially, the oral administration of the saponin-enriched fraction (10-50 mg/kg) potently inhibited the lung inflammatory index. It reduced the total number of inflammatory cells in the bronchoalveolar lavage fluid (BALF). Histological changes in alveolar wall thickness and the number of infiltrated cells of the lung tissue also indicated that the saponin-enriched fraction strongly inhibited lung inflammation. Most importantly, the oral administration of timosaponin A-III at 25-50 mg/kg significantly inhibited the inflammatory markers observed in LPS-induced ALI mice. All these findings, for the first time, provide evidence supporting the effectiveness of A. asphodeloides and its major constituent, timosaponin A-III, in alleviating lung inflammation.

Bamboo leaves (Phyllostachys pubescens Mazel ex J. Houz (Poacea)) have a long history of food and medical applications in Asia, including Japan and Korea. They have been used as a traditional medicine for centuries. We investigated the mechanism of anti-inflammatory activity of a bamboo leaf extract (BLE) on tumor necrosis factor-alpha (TNF-${\alpha}$)-induced monocyte adhesion in human umbilical vein endothelial cells (HUVECs). Exposure of HUVECs to BLE did not inhibit cell viability or cause morphological changes at concentrations ranging from 1 ${\mu}g/ml$ to 1 mg/ml. Treatment with 0.1 mg/ml BLE caused 63% inhibition of monocyte adhesion in TNF-${\alpha}$-activated HUVECs, which was associated with 38.4% suppression of vascular cell adhesion molecule-1 expression. Furthermore, TNF-${\alpha}$-induced reactive oxygen species generation was decreased to 47.9% in BLE treated TNF-${\alpha}$-activated HUVECs. BLE (0.05 mg/ml) also caused about 50% inhibition of interleukin-6 secretion from lipopolysaccharide-stimulated monocyte. The results indicate that BLE may be clinically useful as an anti-inflammatory or anti-oxidant for human cardiovascular disease including atherosclerosis.

In this study, based on the results of analyzing the facilities and operation of the public libraries in Iksan, several strategies that may contribute to its regional development have been established. The strategies are as follows. The first one is to hire more librarians to perform the role of libraries at the advanced level that are suitable for the ever-growing library facilities. The second is the plan for specialization of the libraries, which was proposed with each subject suitable for each library such as History Culture, Modern and Local Culture, Jewelry and Precious metal, Food Cluster, Female, Administration & Welfare, and Environment & Ecology by matching the urban policies and characteristics of Iksan with these library. The others are the operation of English library in the way suggested in this study and the establishment of youth library to build up the role of the libraries in educational city. Through these strategies, the overall function and role of the public libraries in Iksan can be strengthened and emphasized.

The purpose of this study was to find the relationship between osteoporosis and various factors such as general personal background, physical activity, menstruation, daily life and dietary habit. The following are the results of this study: 1. In the relationship of osteoporosis status with general personal background, the risk of osteoporosis increased with age. Active women with higher education, high income and jobs tended to have less risk of osteoporosis. Women with earlier menarche had a tendency of having thicker bone mineral density. 2. As for disease related to bone mineral density, stomach disease, thyroid, bone damage, and bad teeth conditions were significant factors affecting bone mineral density. Women with those diseases and family history of osteoporosis were more likely to have osteoporosis. 3. In relation to food intake regular diet of dairy products, anchovy, or meat showed significantly less risk of osteoporosis. 4. In relation between dietary habits and bone mineral density, unbalanced diet had statistically less probability of osteoporosis. It is important for genetically disposed women to prevent osteoporosis in advance by considering acquired factors like life-style and medication.

To evaluate the effect of different housing systems on sow behavior, 80 gilts were randomly allocated at puberty to four treatments: i) sow stall in gestation followed by farrowing crate (SC), ii) group housing with individual feeding in gestation followed by farrowing crate (GC), iii) ESF (Electronic Sow Feeding) system in gestation followed by farrowing crate (EC), and iv) ESF system followed by group farrowing pen (EG). Behavioral observations were carried out on a total of 16 animals per treatment at the following stages: first day of allocation to housing treatment, day of service, 80 days after service, 109 days after service on entry to farrowing accommodation, 24 h before farrowing, day of farrowing, 14, 27 and 28 days after farrowing, at weaning. On each occasion, individual animals were observed for a 24 period with one minute time sampling. There were significant differences (p<0.001) between stages of the reproductive cycle for all the behavior patterns in all treatments. On the first day in experimental housing treatments, sows spent more time rooting and dog-sitting. Activity and investigatory behavior decreased as pregnancy progressed. An activity peak was apparent just before farrowing, followed by a high level of inactivity on the day of farrowing. Time spent active, eating and drinking increased as lactation progressed, and greatest activity and locomotion was seen immediately following weaning. There were significant differences between housing treatments (p<0.01) for standing, moving, eating, drinking, dog-sitting and lying. During pregnancy SC sows spent more time standing, rooting, drinking and dog sitting, while EC sows spent less time rooting and drinking and more time lying. During lactation, GC sows spent more time standing, moving and eating, less time dog sitting and lateral lying. Nursing frequency was reduced in GC sows (p<0.001). The maternal and piglet behaviors were influenced strongly by environment during lactation. However, it was also shown that previous housing history can influence the maternal behavior in the pre-farrowing stage and during early lactation.

Objectives : Clear and detailed analysis on Pulse-taking on both Carotid and Wrist Pulses is an absolute prerequisite if it is to be applied in real practice or its practical value proven. Methods : The original notes found in Suwen and Lingshu, their translations, and conventional studies regarding Suwen LiuJieCangXiangLun's Pulse-taking are compared and analyzed to find cases within medical texts where this method was used and to get an idea of the direction taken by the conventional study. Results : The ilsung, esung, samsung, and sasung of Carotid (or wrist pulses) refers that the pulse is one-, two-, three-, four-fold in differences. Refrainment should be practiced while comparing carotid and wrist pulses. Rather, they need to be compared with their normal states. Used by Luo Tianyi in Ming Dunasty, this method of pulse-taking was used for (radial artery) when diagnosing and treating the degree of seriousness of food injury. The measurement of maximum blood flow velocity using TCD done recently proved the validity of this pulse-taking, and it's been used for alleviating hypertension or tinnitus through acupuncture, or abating intractable diseases (around carotid). Conclusions : The obscurity of the measuring method of this pulse-taking can be resolved, and the problem which occurs while comparing carotid and wrist pulses can be solved. Even though there are differences in opinion regarding the positions when comparing the two pulses, their practical values are acknowledged since their usages in diagnosis, treatments, experiments, and researches have yielded positive results to a degree. They may not be used that often, but they are nonetheless under utilization.

Plummer-Vinson syndrome is a clinical entity characterized by dysphagia, iron deficiency anemia, cheilosis, glossitis, and cervical esophageal web, especially in middle aged women. Recently, the authors experienced a case of Plummer-Vinson syndrome. A 53-year-old female was admitted due to intermittent solid food dysphagia for 18 months. She had a 2 years history of iron deficiency anemia. On admission glossitis, fissures at the angle of the mouth, spoon nails, and iron deficiency anemia were noted. Esophagogram and esophagoscopic examination revealed thin walled concentric web at upper esophagus. Esophageal web was succefully teared by endoscopic balloon dilatation with subseguant improvement of dysphagia. Skin manifestations as well as anemia were markedly improved after oral iron replacement therapy.
