We investigated middle school students' awareness of Han-style(Korean cuture) in order to promote it, and developed and applied the Teaching-Learning Lesson Plan according to the traditional clothing culture contents related to Han Style. We selected 5 major fields representing Han Style including Han-gul(Korean alphabet). Han-sik(Korean food). Han-bok(Korean traditional clothes). Han-ji(Korean traditional paper), and Han-ok(Korean traditional house). We analyzed the contents of the food, clothing and shelter in 6 types of high school testbooks under the revised 7th national curriculum, and chose seven traditional clothing-lifestyle culture contents. Also we developed 14-period processes and materials(9 for teachers. 9 for students and 3 for and applied it to usual classes. The mean score of middle school students' awareness of Han Style in the post-test was significantly higher than that in the pre-test. Students evaluated it positively that the classes could raise the pride on the Han-culture and provoke the interest in it through the direct experiencing activities. We suggest that the various themes on Han-style should be developed, and the theoretical classes on the identity as well as the experiencing activities on it.

As interest in eco-friendly architecture and Korean traditional culture is increasing, interest in contemporary han-ok is steadily increasing. Recently, many people experienced the han-ok directly and indirectly with the attention of a commercial contemporary han-ok such as restaurants, coffee shops, and lodging facilities, and as a result, the house has a preference for the residence of the contemporary han-ok. Compared to modern residential houses, however, han-ok is lack the convenience of heating and cooling, energy management, security, and maintenance. For this reason, the increased interest and preference for han-ok does not lead to living in contemporary han-ok. This study was conducted in the following ways to improve inconvenience by applying smart home services to contemporary han-ok. Recent technology trends in smart home services and technologies developed and marketed to date have been identified in previous research cases and literature studies. Based on this, a list of smart home services and their application methods were derived that would relieve the inconvenience of contemporary han-ok for smart home services. We hope that this research will serve as a reference for subsequent researchers studying contemporary han-ok.

Hydrazine[$N_2H_4$] is a typical propellant for a rocket fuel in the field of aerospace. Since it is very toxic and harmful to the environment, various environmentally-friendly propellants have been developed. In this study, relatively a safe propellant, hydroxylammonium nitrate[$NH_3OHNO_3$], was prepared via a neutralization reaction of hydroxylamine[$NH_2OH$] and nitric acid[$HNO_3$]. FT-IR was used to analyze the chemical composition, chemical structure and functional groups of HAN. Thermogravimetric analysis showed the decomposition temperature of HAN. Ion chromatography was also used to evaluate the content of nitrate ions. It was proved that the peaks of FT-IR at $3161cm^{-1}$ and $1324cm^{-1}$ indicates the functionalities of N-H and N-O present in HAN. The decomposition temperature of HAN synthesized at pH 5 to 7 was $120-140^{\circ}C$, and pH 8 resulted in higher decomposition temperature than $140^{\circ}C$. Meanwhile, the sample obtained from pH 6-7 showed the concentration of nitric acid ion with 70%.

Found on the 19th century, GuiLinGuBon can have more several unique features than the other extinguish editions. GuiLinGuBon has been Receiving attention, because it contains both and 's contents, as well as it consistt of 16 books to the same as the preperce, and then it analyzed the chapter on Wending Disease(溫病) and Liuyin Disease(六淫病) in detail which is not written in current book, and gives several clues to solve many questions that caused the controversy. This thesis is the study the GuiLinGuBon on the overall composition and the prescriptions for the overall analysis to book configuration, herbs configuration, 8 method(八法) according to the prescribed frequency, SinNongBonChoGyong(神农本草经) according to the herbs of the SamPum(三品) classification and statistical processing GuiLinGuBon the specific features were analyzed.

The purposes of this study were to explain consumer attitude, behavioral intention and behavior(expenses) in the purchase of Han-gwa and to explore the influencing factors on them. To achieve these purposes, the Heckman two-step model was utilized to utilize the recursive system of attitude, behavioral intention and behavior. The results of this study were as follows: 1) Seventy-six percent of consumers presented their favorable altitudes to purchase Han-gwa, while $47\%$ of consumers had behavioral intention for purchasing Han-gwa. In addition, purchasing expense of Han-gwa per year as a proxy variable of behavior was less than 100,000 won for most consumers. 2) First, consumer attitude was found to be significantly influenced by the type of family and food safety. Second, the behavioral intention for purchasing Han-gwa was found to be significantly influenced by consumer attitude, age, income, education and price. Finally, consumer behavior(expenses) of purchasing Han-gwa was found to be significantly influenced by the behavioral intention, income and purchasing place.

Uterine sterilization is important for improving fertility in cattle. This study compared bacterial flora in the uterus between healthy and repeat breeder cows (RBCs). The uterine flushing of six heifers, 13 healthy HanWoo cows and eight RBCs (HanWoo) were sampled, and 15 frozen semen samples were selected. Overall, 35 bacteria were identified from in HanWoo uterine flushing and semen. The bacterial genera identified from HanWoo uterine flushing were Alloiococcus, Bacillus, Enterobacter, Enterococcus, Erysipelothrix, Gardnerella, Granulicatella, Kocuria, Pantoea, Pasteurella, Rothia, Serratia, Sphingomonas, Staphylococcus, Stenotrophomonas and Streptococcus. The bacterial genera identified from HanWoo semen were Bacillus, Escherichia, Kocuria, Oligella, Pseudomonas, Serratia, Sphingomonas, Staphylococcus, Stenotrophomonas and Streptococcus. The prevalence and presence of the identified bacteria between healthy cows and RBCs differed significantly. Further studies are needed to determine the role of these bacteria in the uterus of HanWoo cattle with reproductive disorder.
