"Yixuerumen" is a comprehensive medical text published in the Ming-dynasty by Li Chan(李梴). In this text, Sanghan(傷寒, cold damage) is categorized among external contraction(外感) with much emphasis. The subject of this study is the verse "The Principal and secondary aspects must first be decided." and its annotations in the in the Sanghan chapter of "Yixuerumen". The complex theoretical structure of this verse was firstly analyzed, together with the historical background of how and why Li Chan adopted this concept. The Pyo-Bon concept is the contrast between phenomena(標) and its underlying source of motivation(本). The methodology for this study was to compare and analyze this main verse with contents on Sanghan and Un-gi(運氣) within the text, while reviewing historical theories explaining the physiology and pathology of the human body in terms of the Pyo-bon(標本) concept. As a result, we discovered that the Pyo-bon(標本) concept used in the aforementioned verse of "Yixuerumen" matches the Three Eum Three Yang(三陰三陽)-標本中氣(pyo-bon-jung gi)-gi transformation(氣化) theory of Un-gi(運氣). Li Chan created the connecting link in understanding the Three Eum Three Yang diagnosis system through the viscera/bowels theory(臟腑論) by adopting the Three Eum Three Yang(三陰三陽)-標本中氣(pyo-bon-jung gi)-gi transformation(氣化) theory from Un-gi. Li's work lead to several changes in the field of Sanghan. First, Li understood the disease pattern of Sanghan by using the accumulated knowledge of the viscera/bowel theory during the Jin-Yuan dynasty, and developed a medical perspective that observes the disease pattern based on the body's essence gi(精氣). Second, he set the category of the Sanghan-Three Eum Three Yang disease pattern, establishing a separate guideline. Third, by adding knowledge of herbs to the accumulated knowledge of the viscera/bowel theory, the process of diagnosis and herbal application were made explicable. On the other hand, in the process of interpreting the 三陰三陽 diagnosis system with viscera/bowels theory, theoretical inconsistencies appeared, of which Li tried to mend by several means. The results of the research on "Yixuerumen(醫學入門) the Sanghan chapter(傷寒篇)" calls for further studies, as it has effected both "Dongeuibogam(東醫寶鑑) the Sanghan part(寒門)" and "Dongeuisoosebowon(東醫壽世保元)" as well.

Digital environment that is represented to Internet is displacing business way of industry and business achievement way with the fast speed being giving great change on life whole. Improve existent business process utilizing Internet and Web connection technology, information superhighway to tradition industrialist manufacturer and e-Transformation's propulsion that wish to maximize productivity and administration efficiency is spread vigorously. In this paper, administration efficiency raising of Web-based factory monitoring system to do monitoring when everywhere integrating operation present condition current point of time of discrete factories in inside and outside of the country by purpose design and implemented. That is, do to normalize system structure and achievement function, and administration data of Web-based, and design using VML (Unified Modeling Language) and take advantage of ASP (Active Server Pages) and implemented web function. Implemented Web-based factory monitoring system is applying two factory (Kl, K2) of K CO., LTD. tire operation division to caravan, and application result was evaluated by very efficient thing to grasp operation situation of whole factory synthetically.

To study the effects of patenting temperature and isothermal holding time on the phase transformation and mechanical property changes of SAE 1078 steel, the patenting process was performed at 460℃, 560℃, and 660℃ for isothermal times (30 s, 60 s, 90 s, 120 s, and 150 s) after nitrogen cooling under austenitizing conditions (1000℃, 2 min). In this study, a scanning electron microscope was used to measure the microstructure and interlamellar spacing of pearlite according to process variables, and an X-ray diffraction analyzer was used to calculate the phase fraction. Cooling rate is approximately 18.6℃/s from the austenitizing temperature to the patenting temperature and pearlite transformation begins at 597~602℃. As the patenting temperature increases, the rate of carbon diffusion during isothermal step increases, so a relatively coarse pearlite structure is formed, and the hardness tends to decrease overall. As the isothermal holding time increased, the hardness of the treated specimens converged to 420Hv, 376Hv, and 268Hv, respectively, because the phase transformation was sufficiently completed at 460℃, 560℃, and 660℃. On the other hand, as the isothermal holding time became shorter, sufficient phase transformation did not occur after the isothermal process, so retained austenite existed, resulting in a decrease in hardness.

Restriction enzyme-mediated integration(REMI) was used to transform uracil auxotrophs of Pleurotus ostreatus to prototrophy. When protoplasts of Pleurotus ostreatus were treated by the reaction mixture containing 10 units of BamHI, the frequency of REMI was about 64 transformants per 1 ${\mu}g$ of DNA. This efficiency was increased by 14.2 times compared with that of the conventional PEG transformation. The optimal condition for REMI of P. ostreatus was achieved when 1 ${\mu}g$ of linearized pTRura3-2 DNA was added into $1{\times}10^7$ protoplasts along with 10 units BamHI. Southern blot analysis revealed that about 50% of transformants examined were caused by REMI event and 30% carried single copy insertion at the genome. This suggested that the REMI method might be a useful tool for efficient transformation and tagging mutagenesis of P. ostreatus.

Oral leukoplakia is the most common premalignant lesion and malignant transformation has been reported from verrucal lekoplakia. Homogenous, benign leukoplakia develops into a line of squamous cell carcinoma such as verrrucous carcinoma, papillary squamous cell carcinoma and invasive squamous cell carcinoma. Early diagnosis and intervention of premalignant leukoplakia is up-most important to prevent transformation into a oral squamous cell carcinoma. Any change in surface, size and color warrants repeated biopsy. If verrucous carcinoma is evidently derived from the previous leukoplakia, wide surgical excision and periodic follow up is needed. Surgically removed lesion of leukoplakia has the tendency to recur. Follow-up is very important to patient and clinician. Although many therapies have been reported to oral leukoplakia and verrucal carcinoma, accepted treatment principle is not exist so far. But surgical removal is recommended as the treatment of choice.

In this study, abiotic transformation of 1-naphthol via oxidative-coupling reaction was evaluated using Mn oxide which is ubiquitous in natural soils. The transformation of 1-naphthol catalyzed by synthetic birnessite $({\delta}-MnO_2)$ followed pseudo-lst order reaction, and the rate constants was in the range of $0.053{\sim}0.13\;min^{-1}$ with birnessite loadings of $12.5{\sim}50\;mg/20\;mL$. Since the oxidation of 1-naphthol was occurred on the reactive surface of the oxide particles, the rate constants with various birnessite loadings were correlated with birnessite surface area concentration. The correlation showed a strong linearity, which confirms the supposition of the surface reaction. From the correlation, therefore, the surface area normalized rate constant, $k_{surf}$, was determined to be 0.032 $L/m^2\;min$.

In hot press forming process, the desired high strength can be obtained through quenching process after cold forming of product. The quenching process, however, accompanies undesired distortion due to the volume change during the phase transformation as well as by thermal contraction. In this study the numerical simulation with DEFORM3D-Microstructure is used to predict the deformed shape during the quenching for the quenching fixture design.

A fundamental tenet of CBD is that a component has a specification which describes what that component does, and how it behaves when its services are used. In general, the implementation may be written in a different programming language and execute on different technology platform, from the language and platform used by the client program. In order to implement practically the system that is designed by the Farmer model, there is need to have the ISM (Interface Specification Model) which explains specification about the functions of entities of the Farmer model, such as, entity node, aspect node and ILB/OLB. This paper suggests the transformation methodology from the concepts of the Farmer model to the mapping notions of the ISM. Also in reality, TMN agents system which is designed by the Farmer model is transformed to the ISM system design.
