YangDongChangHwaHuRok(兩東唱和後錄)is a book that organized the conversation between Joseon physician Ki-DuMun(奇斗文) and Japanese Acupuncture specialist Murakami Tanio(村上溪南) and others when they visited the quarters where the Choson Delegation(朝鮮通信使) were staying in, while the Choson Delegation party were visiting Japan in 1711. YangDongChangHwaHuRok(兩東唱和後錄) was discovered in the process of gathering medicine-related historical documents of the Choson Dynasty that is spread out all over the Japanese region, with the help from Japanese and Chinese scholars. This was part of the Co-Examination-Research-Process of korean medical documents that are located in the East Asia traditional medical region, which was promoted by the Korean Institute of Oriental Medicine in 2003. This paper has analyzed in-depth, with an inner-medical view, the academic exchange content of YangDongChangHwaHuRok(兩東唱和後錄) by following the order of the main text. With this examination, we were able discover new facts about the interest in Primary Symptom(是動病) and Secondary Symptom(所生病) of 17th century doctors, a new hypothesis on the diffusion of HeoYim(許任)'s ChimGuKyungHeomBang(鍼灸經驗方) in Japan, the existence of a new acupuncture tool called ChongChim(腫鍼), and the influence of the 18th comtemporay famous traditional medical books (it is called UiHakYipMun(醫學入門) and ShinEungKyung(神應經) on the 18th century East Asian medical circle. We were also able to ascertain the specific medical content that was diffused to the Japanese medical circle by the Korean medical circle.

This is a study of CHOK-DU-RI(族頭里) a black crown-like headpiece worn by woman on formal occasion in Chosun Dynasty and has succeeded until now. CHOK-DU-RI was originated by BOKTAK worn by Mongolian noblewomen and inflowed to the last period of Koryo dynasty under occupation of Yuan. The documentary records of O-JU-YON-MUN-CHSNG-JON-SAN-KO( by Lee Kyu-kung CHUNG-JANG-KWAN-JON-SUH by Lee Tock-mu and KO-SA-TONG by choe Nam-sun verify CHOK-DU-RI is a custom of mongolian fusion that was affected by KO-KO of Yuan and was formed. Ko-Ko is the same as BOKTAK. It is assumed KO-KO is a borrowed name as its transcription varies. The name was given according to its appearance which is certified by the record CHANGCHUN-CHIN-IN-SEO-BANG-YU-RAM-KI. It says that it can be simply named KO-KO as its edge is alike ad goose or a duck. In addition KO-Ko was called CHOGTAI in case of being added a camel fur that is JUGDUR. CHOGTAI similarily pronounced with CHOK-DU-RI which of being added a camel fur that is JUGDUR, CHOGTAI similarily pronounced with CHOK-DU-RI which provd CHOK-DU-RI was originated in Mongol. The shape of BOKTAK is very high and wided toward the top with the top with the angle getting more pointed and a feather stuck on the side. But its height got lower and its size smaller as it did gradually Koreanized to a CHOK-DU-RI. The use of CHOK-DU-RI has been settled since the last period of Chosun Dynasty. It came to stay as a popular custom when King Young-jo and Jong-jo wanting to do away with the corrupt practice of KA-CHE encouraged women at that time to do their hairs with CHOK-DU-RI instead of KA-CHE. It is as follows the classification of CHOK-DU-RI. First classified by a use group is divided into ceremonial use such as the seven treasures CHOK-DU-RI and jeweled CHOK-DU-RI. Hereby it is assumed that CHOK-DU-RI was used regardless of fortune. Secondly it varies by its type of frame. There are SOM CHOK-DU-RI OHT CHOK-DU-RI and O-YOM CHOK-DU-RI a kind of SOM CHOK-DU-Ri formed a base of O-YOM-MO-RI. The third group by jeweling has WHE-BONG CHOK-DU-RI and TA-BONG-CHOK-DU-RI JEwele CHOk-DU-RI can be still seen being commercially lent and worn by the brides at nuptical ceremonies performed in tradition of fashion and when worn bya bride as she gives her parents to her parents-in-law.

In this paper, we propose a group distributed dynamic address assignment scheme suitable for tactical mobile ad hoc networks(MANET). Efficient address assignment is an important issue in the MANET because a node may frequently leave the current network and join another network owing to the mobility of the node. The conventional schemes do not consider the features of the tactical networks: existence of a leader node and network activity on a group basis. Thus, they may not be suitable for military operations. In our proposed scheme, called grouped units dynamic address assignment protocol(G-DAAP), a leader node maintains the address information for the members in the network and any of the nodes can exploit the information for the assignment or request of the IP address by a simple message exchange procedure. This leads to fast address assignment with small overheads. In addition, G-DAAP based on the modified IEEE 802.11e Enhanced Distributed Channel Access(EDCA) can assign addresses more quickly. We describe the delay performance of the G-DAAP and compare it with conventional schemes by numerical analysis and computer simulations. The results show that the G-DAAP significantly improves the delay performance as compared with the conventional schemes.

The pedigree data of 86,639 heads from six major swine breeding farms were investigated to check levels of inbreeding and effective population size of breeding stocks. The average rate of inbreeding was 1.04%, 0.87%, 3.17%, 1.05%, 3.23% and 3.33% for farms A, B, C, D, E and F, respectively. The average inbreeding rate was highest for F farm and lowest for B farm. In farms D and E, there were quite large numbers of immigrant animals per generation compared to other farms. The effective population sizes calculated from the average rate of inbreeding were distributed between 83.0 and 814.8. Specific values were 282.3, 225.5, 83.0, 814.8, 302.9 and 175.7 for farms A, B, C, D, E and F, respectively. The results showed that there was no cause for concern over the current inbreeding level of major swine breeding farm populations and the inbreeding level was within an acceptable range. In addition, internal sharing rather than importing pig is necessary to strengthen seed sovereignty.

In this study, the bioactivities of ethanol (EELS) and water extract (WELS) from the leaf of Lythrum salicaria L. were investigated. In the anti-cancer activity, the growths of both human prostate cancer (DU145) and human colonic carcinoma cell (HT29) were inhibited up 60% by adding 10 mg/$m{\ell}$ of EELS. Anti-inflammatory activity of EELS and WELS have been evaluated on lipopolysaccharide (LPS) induced release of nitric oxide (NO) by the macrophage RAW 264.7 cells. EELS and WELS inhibited inflammatory by 57.3 and 46.9% in 10 mg/$m{\ell}$, respectively. In the anti-oxidative activity, $IC_{50}$ of DPPH radical scavenging activity was respectively 60.71 and $92.90\;{\mu}g/m{\ell}$ by EELS and WELS. In the anti-diabetic activity, $IC_{50}$ of ${\alpha}$-amylase inhibitory activity of EELS and WELS were respectively 5,250 and $5,020\;{\mu}g/m{\ell}$. $IC_{50}$ of ${\alpha}$-glucosidase inhibitory activity was 7.96 and $68.41\;{\mu}g/m{\ell}$ by EELS and WELS. In the anti-obesity, $IC_{50}$ of lipase inhibitory activity was 880 and $9,840\;{\mu}g/m{\ell}$ by EELS and WELS. Finally, EELS and WELS exhibited anti-oxidative, anti-inflammatory, anti-diabetic activity and anti-obesity. It suggests that Lythrum salicaria L. could be potentially used as a resource of bioactive materials for health functional foods.

As the time-to-market gets more important for competitiveness of an enterprise in manufacturing industry, it becomes important to shorten the development cycle of a product. Reuse of existing design models and e-Catalog for components are required for faster product development. To achieve this goal, an electric catalog must provide parametric CAD models since parametric information is indispensable for configuration design. There are difficulties in building up a parametric library of all the necessary combination using a CAD system, since we have too many combinations of components for a product. For example, there are at least 80 million combinations of components on one page of paper catalog of a mold base. To solve this problem, we propose the method of table parametric for the automatic generation of parametric CAD models. Any combination of mold base can be generated by mapping between a classification system of an electric catalog and the design parameters set of the table parametric. We propose how to select parametric models and to construct the design parameters set.

The suitability of the life Cycle Assessment (LCA) methodology to analyze the environmental impact of rice cultivation with different fertilizing systems is investigated. The arst part of an LCA is an inventory of parameters used and emissions released due to the system under investigation. In the following step, the Life Cycle Impact Assessment the inventory data were analyzed and aggregated in order to finally get one index representing the total environmental burden. For the life Cycle Impact Assessment (LCIA) the Eco-indicator 95 method has been chosen because this is well documented and regularly applied impact assessment method. The resulting index is called Eco-indicator value. The higher the Eco-indicator value the stronger is the total environmental impact of an analyzed fertilizing system. The rice field experiment conducted in middle parts of korea was chosen as an example for the life cycle impact analysis. In this experiment the treatments were consisted of none fertilizer plot (NF), standard fertilizer plot (SF) applied chemical fertilizers based on soil chemical analysis before rice transplanting, and efflux fertilized plot (EF) applied with pig wastes fermented as the same rates of SF plot as basis on total nitrogen content. The obtained Eco-indicator values were clearly different among the treatments in the rice trial. The total Eco-indicator values for SF and EF have been observed 58 and 38% relative to the NF, respectively. For all the treatments the environmental effects of eutrophication contributed most to the total Eco-indicator value. The results appeared that the LCA methodology is basically suitable to assess the environmental impact associated with different fertilizer applications for rice cultivation. A comparative analysis of the fertilizing system's contribution to global warming and eutrophication is possible.
