In our previous study, a novel herb mixture (HIM-I) of Angelica gigas radix, Cnidium officinale rhizoma, and Paeonia japonica radix was developed to protect the intestinal and immune systems and promote its recovery against radiation damage. A new herbal composition (HemoHIM) with the high immune modulating activity was developed from HIM-I. HIM-I was fractionated into ethanol fraction (HIM-I-E) and polysaccharide fraction (HIM-I-P). And HemoHIM was prepared by adding HIM-I-P to HIM-I. HemoHIM showed more effective than HIM-I in immune modulation as well as radioprotection. The present study is designed to investigate the protective effects of HIM-I, HIM-I-P, and HemoHIM on hydrogen peroxide $(H_2O_2)$ induced apoptosis of human promyelocytic leukemia (HL-60) cells. It was shown that $H_2O_2$ treatment reduced the viability of cells, and increased appearance of DNA ladders, hypodiploid (subG1) cells, and phosphatidylserine translocation level. Pretreatment of HemoHIM significantly reduced the cytotoxic effect induced by $H_2O_2$, associated with reducing the translocation of phosphatidylserine, hypodiploid cells and DNA ladders. HemoHIM appeared to be more protective than HIM-I against $H_2O_2$ induced apoptosis whereas, it exhibited similar activity to HIM-I-P. These results indicated that HemoHIM might be an useful agent for protection against oxidative stress $(H_2O_2)-induced$ apoptosis as well as immune modulation, especially since it is a relatively nontoxic natural product.

The author fractographically analyized the cause of metal failure(the first time this procedure has been used for this metal failure)and also analyized it clinically. In this study, I selected eight cases which have been analyized fractographically. In all these cases, the analysis was done after treatment of metal failure of implants internally fixed to femur shaft fractures at the Department of Orthopedic Surgery, Yeung-Nam University Hospital during the six year period from May 1983 to September 1989. 1. Metal failure occured in five dynamic-compression plates, one Jewett nail, one screw in Rowe plate, and one interlocking nail. 2. The clinical cause of metal failure was deficiency of medial butress in five cases, incorrect position of implant in one case, and incorrect selection of implant in two cases. 3. The time interval between internal fixation and metal failure was four months in one case, between five months to twelve months in six cases, three years in one case. 4. The fractographically analytical cause of metal failure was ; first, impact failure, one case, second, fatigue failure, six cases, machining mark(stress liser), four cases type : low consistent cyclic fatigue failure irregular cyclic fatigue failure third, stress corrosion crack, one case. 5. 316L Stainless Steel has good resistance to corrosion. However, when its peculiar surface film is destroyed by fretting, it shows pitting corrosion. This is, perhaps, the main cause of metal failure. 6. It is possible that mechanical injury occured in implants during the manufacturing of implants or that making a screw hole is the main cause of metal failure.

This article is to study the life and philosophy of Jonjae Gidaeseung, who was at strife with his days and did not negotiate with himself, with focus on two concepts of buron(不穩, unrest) and 'sympathy'. It is the fact that to study the traditional philosopher is likely to be enlightening. In order to prevent the risk, we need to define first the concept of unrest as including anxiety to critical resistance. Also, I would like to propose the concept of sympathy in order to grasp the function of his mind which judges whether his feelings and actions are valid from an emotional horizon of unrest. Methodologically this article is to adopt a transversal and correlative thinking by combining an east Asian Confucian traditional concept unrest with a modern one space. It is because this research is to show a significant meaning when we study highlighted and hidden layers of our life and politics in 'now-here' and the 'between space' even though this transversal and correlative study shows the horizon of his life. This article is to investigate how a case is structured by occurrences and divergences and reinterpret a meaning from an emotional horizon. This process is done centering on two terms Guchatuan(pursuing ease ignobly), and Suwolbingho(moon reflected in the water and ice in a bottle), which is the source of Bingwoldang. The two terms were used by Jonjae himself. The latter shows an opposite meaning from the first and is accordingly a way by which we can look into his life and days. My research of Jonjae's life and politics from the emotional-philosophical level is original in that it reveals emotional traces beyond his philosophical ideas which previous studies did not show. In this article, I showed that Gobong was ambitious and resolute, and definite in his judgment and therefore was not good at controlling his uprightness. Also he was too straightforward to purify a language. His unrest characters made him conflict with old ministers and high ranking officials and therefore they avoided him even thought he was excellent in writing and learning and talented. He was oriented toward living by goodness and right Ways, which is summed up as Gisesa(vague movement, situational advantage, and death).

In order to evaluate suitability by processing for non-GM soybean cultivars such as Gaechuck#2, Jinyangkong and CJ#1 lacking lipoxygenase (LOX) and kunitz trypsin inhibitor (KTI) protein, physicochemical characteristics and antioxidant activity of Kanjang made from above soybean were compared to Kanjang made from a conventional cultivar (Taekwangkong). Proximate compositions of soybeans were similar for the 4 kinds cultivars. Total phenol and flavonoid contents were significantly higher in cultivars lacking LOX and KTI protein than the Taekwangkong. In Kanjang, contents of total and reducing sugar were higher in Taekwangkong Kanjang than Kanjang from made cultivars lacking LOX and KTI protein. Contents of total and amino type nitrogen were the highest in the Jinyangkong Kanjang. Mineral contents were higher in the Jinyangkong and CJ#1 Kanjangs, amino acid contents were higher in the Kanjang made from 3 cultivars lacking LOX and KTI protein than the Taekwangkong. Taste of the Jinyangkong Kanjang with higher sweety and savory was also found to be superior to that of others in overall acceptability evaluation. Total phenol and flavonoid contents in Kanjang were significantly higher in the Kanjang made from cultivars lacking LOX and KTI protein than the Taekwangkong. Radical scavenging activity of Kanjang was increased in the total phenol contents dependent on. Reducing power by ferric-reducing antioxidant potential (FRAP) was significantly higher the Kanjang made from Gaechuck#2 and CJ#1 than the Taekwangkong. $Fe^{2+}$ chelating activity was higher in Taekwangkong Kanjang than the other cultivars, but its activity was similar to Jinyangkong Kanjang. Therefore, higher nutritional composition, total phenol and flavonoids contents and antioxidant activity in the Kanjang made from soybean cultivars lacking LOX and KTI protein might be provide better benefit for manufacture of another their products.

The aim of this study was to investigate the quality properties of beef jerky replaced salt (NaCl) with red pepper paste, soy sauce and soybean paste. The quality properties of beef jerky including water activity ($a_w$), pH, moisture content, protein content, color, shear force, texture profile analysis and sensory evaluations were investigated. The sliced beef samples were marinated at salt (control), soybean paste (T1), soy sauce (T2) and red pepper paste (T3) for 24 h and then dried at $70^{\circ}C$ for 8 h. The $a_w$ and moisture content varied from 0.88 to 0.79 and from 28.87% to 22.98%, respectively. All treatment samples showed higher final $a_w$ and moisture content than the control sample after drying for the 8 h (p<0.05). The protein content of T2 and T3 samples were lower than the control. Also, shear force and hardness value of all treatment samples had lower than the control (p<0.05). However, all treatment samples showed lower saltiness intensity than the control sample. Sensory panelists recorded greater flavor and texture scores to the samples with soy sauce replacement. Therefore, sensory panels found that the T2 samples had better overall acceptability scores than the other beef jerky samples (p<0.05).

This paper examines the differences of two different versions of "Cheonuisogameonhae" in terms of stylistics and investigates factors affecting the differences. The interpretations between the woodblock edition and the manuscript edition might be different depending on assumed range of readership, and the stylistic differences between two editions might be different depending on the possibility of extension of the reading population. Thus, this paper examines how stylistic effects are reflected in inter-relations between a translator as a speaker and readers as listeners according to speaker intentions. In Chapter 2, the stylistic differences reflected from two difference editions are examined in terms of the expression of a writer's respect, emotions, and formal consciousness to readers. The expressions of a writer's respect are more clearly emerged in the manuscript edition than in the woodblock edition. The honorific expression of a subject, '-gyeo?dsyeo', and the honorific expression of a writer, '-s?p-', are more frequently used in the manuscript edition than in the woodblock edition. In order to express positive emotions, exclamation endings are used in the manuscript edition, which shows the writer's strong emotional sympathy with readers' words and behaviors. On the other hand, in the woodblock edition, '-이' is used after names in order to treat rebellious subjects and people involved in conspiracy contemptuously by the use of informal forms. In addition, affirmative sentences in the manuscript edition and double negative sentences in the woodblock edition are used respectively, which intends to strongly emphasize a king's will and the appropriateness of the will. The writer's formal consciousness to readers are found in the way of writing names of people and places in Korean. Chinese characters are generally used two show formal consciousness; thus, names of people and places are expressed in Chinese characters in the woodblock edition. In Chapter 3, factors that made the stylistic differences between two editions are examined. The factors causing stylistic differences are examined in terms of the purpose of the interpretation, the class and range of the reading population, a writer's attitudes toward readers, and the face-to-fact situation of a writer and readers.

"Olgreen" (Scale cereal L.), a new rye variety was developed by National Institute of Crop Science(NICS), RDA. It was released in 2008 because of its high biomass yield potential and early maturity. It was developed from an open pollination within 10 rye varieties or lines including "Chochun" in 1995. The line 'SR95POP-S1-1072-1-2-4' was selected for its early maturity and excellent agronomic appearance, and placed in yield trials for two years from 2004 to 2005. It was designated "Homil 38" and placed in regional yield trials at the four locations around Korea from 2006 to 2008, from which the name "Olgreen" was given. Over three years, "Olgreen" averaged 8.88 ton ha-1 of forage yield (based on dry matter) harvested at late April and superior to other varieties with an increase of 10% more than the check variety "Olhomil", and 9% more than the introduced rye "Koolgrazer". Heading date of "Olgreen" was April 20 which was 3 days earlier than that of "Olhomil". It would be recommended as an early rye variety for forage or green manure in South Korea.

A new naked oat cultivar Daeyang (Avena sativa L.) was developed by Department of Rice and Winter Cereal Crop, NICS, RDA in 2007. It was derived from a cross between 'FLX446-1-84-Q1'. and 'SO92004-B-3-3-5-7'. The FLX446-1-84-Q1, a naked oat cultivar from USA, is early heading and has good seed quality, while the SO92004-B-3-3-5-7, a covered oat breeding line, has a high yield with large grain. Subsequent generations were handled in a bulk method and pedigree selection program, and the SO97013-B-16-4 was selected based on agronomic performance in 2001. The line showed both high yield and good husking rate of seed in the yield trial tested at Suwon from 2002 to 2003, being designated as Gwiri51. The Gwiri51 was subsequently evaluated for winter hardiness, earliness, and yield in four locations, Gimje, Iksan, Jeongeup, and Jinju, from 2004 to 2007 and was designated as "Daeyang" and released. Its heading date was May 8 and maturing time was June 14 in a paddy field condition. The new cultivar Daeyang had 97 cm of culm length and 25.2 cm of spike length, 644 spikes per $m^2$, 65 grains per spike, 30.3 g of 1,000-grain weight, and 635 g of test weight. Daeyang showed better winter hardiness than that of the check cultivar 'Sunyang', and similar seed quality to the check cultivar in respect to percent content crude protein and $\beta$-glucan. However, it showed higher husking rate than the check cultivar. Grain yield of Daeyang in the regional yield trial for 4 years were averaged 4.18 MT $ha^{-1}$, which was 20% higher than that of the check cultivar Sunyang. Fall sowing cropping is recommended only in a south area where daily minimum mean temperatures are averaged higher than $-4^{\circ}C$ in January, and should be excluded in mountain area where frost damage is presumable.

This study was conducted to estimate genetic parameters for reproductive traits using multivariate animal models in Yorkshire breed. For the study, 4,989 records for litter traits collected between the year 2001 and 2005 from Yorkshire pigs in K GGP were used. The effects of environmental factors such as farrowing year, parity, weaning to estrus interval (WEI), and suckling period were statistically significant (p<0.05), but farrowing season was not significant, for reproductive traits. The estimates genetic correlations and phenotypic correlations in total number of born and number of suckling, was shown to highly correlated. The genetic correlations were higher than phenotypic correlation. The estimates of heritabilities for reproductive traits, considering permanent environment effects (PE) were much lower than those obtained when permanent environment effects were not considered (NPE) in the model. The estimates of heritabilities were 0.240 and 0.076 for total number of born and 0.187 and 0.096 for number of suckling in NPE, and PE, respectively. These results itivcate that PE should be considered in the statistical mode to estimate more acco ate breeding values.

We used a multiplex PCR primer set composed of 11 microsatellite (MS) markers and two sexing markers for gender detection. Genomic DNA extracted from hair roots of 3,510 Hanwoo were genotyped. Based on the 11MS markers, no animals had identical genotypes(TGLA227, BM2113, TGLA53, ETF10, SPS115, TGLA122, ETH3, ETH225, BM1824 and INRA23). The expected probability of identity among genotypes of random individuals (PI), the probability of identity among genotypes from random half-sibs ($PI_{half-sibs}$) and among genotypes of random individuals, and the probability of identity among genotypes from random sibs ($PI_{sibs}$) were estimated as $1.31{\times}10^{-23}$, $2.52{\times}10^{-16}$and $1.09{\times}10^{-6}$, respectively using the API-CALC program, version 1.0. We successfully completed the genotype analysis of 3,510 Hanwoo with a 3.93% genotyping failure rate. It was revealed that extracting DNA from the hair root was a time-efficient and cost-effective method to collect specimens for DNA isolation from live animals. This method also minimized stress for the animals during specimen collection. Among the hair roots from the back, belly, upper tail and lower tail, 5~13 hair roots of the lower tail led to the best genotype analysis results. Finally, we established a 96-well-format method of DNA preparation applicable for high- throughput genotype analysis.
