This paper includes five cases about patient with pruritus and erythema by External Gi-Gong Therapy(EKT) for two days. We judged the patient who has pruritus and erythema, and treated them with External Gi-Gong Therapy(EKT). EKT has always been part of the medical Gi-Gong practice. EKT refers to the process by which a Gi-Gong practitioner directs his intention, or emits his Gi energy, to help others break Gi blockages and induce the sick Gi out of the body so as to alleviate the pain, abate the disease, and balance the flow of Gi. We expect that External Gi-Gong Therapy is effective for patient with pruritus and erythema.

A vehicle fuel economy is one of the most important issues in view of environmental regulation and customer's needs. In order to improve the vehicle fuel economy, great efforts has been carried out on the components bases. However, systematic analysis of vehicle fuel consumption is necessary for the further improvement of vehicle fuel economy. In this paper, a methodology for the breakdown of vehicle fuel consumption was studied and proposed for systematic analysis of the vehicle fuel economy. The energy equation for the vehicle power train was set up for the analysis of the vehicle fuel economy and simplified to be calculated or estimated using the measured data in a vehicle. The amount of fuel that was used in vehicle components under arbitrary driving conditions was quantified.

Presently, there are some means of voyage estimations such as Hire base, Charter base, and Anticpated income and expenditure statement of voyage. The former two are the means of estimation for profit of a ship's voyage per a deadweight tonnage adn a month, and it is well used in the case of chartered ships. But it is somewhat meaningless for the shpowner who runs his ships for himself. The latter means for estimation is mainly used in western shipping, and do not set forth simpler way of comparing profit with another voyage or with another ship's employing in other route. And this paper has yielded an index of ship's voyage profit evaluation by building a model of ship's voyage evaluation formula, and the index may be used in evaluation of the new investigation of shipping as well as setting out a shiop in a voyage. The model has yielded a break even curve which may be used for deciding the amount of demurrage and the period of ship's port time for a specific voyage contraction.

Experimental and theoretical studies on the air-assist coaxial atomizer have been continuously carried out for a long time. But now the importance of the theoretical study is tending to increase as with the development of computer. This study is concerned to the spray modelization, especially, the instability of the liquid jet surrounded by the air stream which flows with high velocity. To study the phenomena of the break up, we used the linear theory based on the classical Kelvin-Helmholtz theory for capillary wave at a simple interface and we investigated the variation of liquid core radius. As a result, we obtained that the drop diameter and the variation of the liquid core radius predicted by using our model are reasonable.

Blends of ethylene-propylene-diene terpolymer(EPDM) and high density polyethylene(HDPE) have been prepared in a roll mill by the process "dynamic curing" where both blending and a crosslinking reaction was carried out simultaneously. As a crosslinking agent, dicumyl peroxide(DCP) was used. Throughout the experimental ranges, the dynamically cured polyblends were shown to be thermoplastic elastomers except highly crosslinked blends of high compositions of EPDM. The increase of melt viscosity was observed as EPDM composition and DCP contents increased. From DSC determinations, the crystallinity decreased with increasing contents of DCP. The tensile strength and elongation at break generally increased with increasing DCP content and increasing HDPE compositions, but highly depended on the combined effects of decreasing crystallinity and increasing crosslinking density.

This paper focuses on the specificities and semantic meaning of Mikhail Bulgakov's metadrama White Guard and The Flight. The standard conception of metadrama is to purposefully break the dramatic illusion and make bare a playwright's self-consciousness of the theatrical art itself. With the use of the metadrama Bulgakov expressed the essentials of ugly reality, which he couldn't accept as a valuable truth. In this respect, Bulgakov's metadrama becomes at once a window, from which he views the external world in the theatrical vision, and a mirror, in which his political and existential stance as a playwright is reflected. In White Guard Bulgakov described the already theatricalized reality through several instances of 'play-within-play'. In The Flight, composed of eight pieces of dream, a life turned out to be a less solid and less firm reality than dream. Continuously demolishing the cognitive wall between reality and illusion, Bulgakov leads spectators to have a reflective view on the reality. Allowing more powerful demonstrativeness for a play-within-play than for a play-within-play, Bulgakov elevates a metadramatic technique to the level of thematic structure.

Over the last decade, the field of Southeast Asian Studies has been inundated with issues of its "territory" (or the definition of what comprises Southeast Asia), relevance and future. The methodology of approaching Southeast Asian Studies has also come under constant scrutiny providing much fodder for debate. One significant suggestion was that the field of Southeast Asian Studies should "break out of the comfort zone" (Van Schendel, Bijdragen, 2012:168(4)). This paper will explore some of the ways of approaching Southeast Asian Studies beyond that comfort zone by examining other/alternative units of studying Southeast Asia in place of the traditional (or statist) perspectives that tend to confine the field within the scope of the national/nation-state boundaries. The paper will also provide some personal observations of the author on the current state and limitations to teaching and researching Southeast Asian Studies in the region.

A proprietary device is adopted to break out the membrane of cell in the rigid polyurethane foam. As it is known, the membrane of cell is hardly tearing-off thoroughly in a mechanical way due to both its elastic characteristic and micro sized pores. In this study, a novel experimental approach is introduced to burst out all gases inside the cells of the rigid polyurethane foam by abrasively grinding micro-cells completely into fine powder. The biggest advantage of this approach is to be capable of releasing all gases out from the cell even in the micro pores. As clearly reflected from the repeatability, the accuracy of the result is highly improved and high confidence in the data sets as well. For the measurements of not only gas composition but partial pressure for each gas simultaneously as well, a precision gas mass spectrometer is used in-line directly to the abrasive grinding device. To control the starting point of the polyurethane foam, all samples were prepared on site in the laboratory. Manufactured time is one of the most critical factors in characterization of cell gas composition because it is known that one of gas composition, especially, carbon dioxide, is diffused out dramatically in a short period of time as soon as it is foamed.

This study was designed to know the possibility in repeat uses of elite donor cows for getting mass production of OPU-derived embryo production (OPU-IVP). Ultrasound transvaginal ovum pick-up (OPU) performed in 6 Korean native cows was aged 4 to 10 years old. The aspiration of immature oocytes for OPU derived embryo was carried out 2 times per week, and OPU-IVP of $1^{st}$ period was carried out 22~48 sessions from each donors. And the break time for OPU-IVP of $2^{nd}$ period after $1^{st}$ OPU from each donors were 2~25 months. The OPU-IVP of $2^{nd}$ period each donors conducted total 15~65 times for 2~8 months by an ultrasonographic, was guided follicular aspiration system. The average numbers of collected oocytes, grade 1 + grade 2(G1+G2) oocytes and cleavage embryo from $1^{st}$ period OPU-IVP were significantly differences between donors (p<0.05). Total collected oocytes of donor D were significantly higher compared with donors of A, B, C, E and F (average 17.0 per session vs. 11.2, 10.1, 8.5, 10.2 and 9.6; p<0.05) and also oocytes of G1+G2 were significantly higher compared with r A and D and subsequently to donors of B, C, E and F (average 7.9 and 8.5 per session vs. 5.0, 2.7, 6.0 and 1.6; p<0.05). Cleavage rate of donor D was significantly higher compared with donors of A, B, C, E and F (average 13.1 per session vs. 10.1, 9.1, 6.9, 8.9 and 6.7; p<0.05). The average numbers of OPU-IVP for $1^{st}$ period was significantly higher from donors of B, D and E than those from donors of A, C and F (average 6.5, 7.1 and 6.5 per session vs. 3.5, 4.2 and 2.8; p<0.05). The possibility investigation of $2^{nd}$ OPU-IVP was carried out after 2~25 months rest periods from $1^{st}$ period OPU session. Total average numbers of collected oocytes, cleavages and blastocyst development rates were significantly higher from $1^{st}$ period OPU compared with $2^{nd}$ period one (p<0.05). The OPU-IVP efficiency by break for more embryo production from elite cow was analysis comparing without rest of donor A, under 6 months rest period as B and over 6 months rest period as C and then the average numbers of collected oocytes, cleavages and blastocysts were significantly higher from A group (11.8, 9.5 and 5.2 per session) than those from B and C groups (7.9, 6.2 and 2.6 vs. 9.2, 7.5 and 3.9, p<0.05), and also C group was significantly higher than B group. In conclusion, $1^{st}$ period OPU-IVP was more efficient compared with $2^{nd}$ period repeated uses of donor, and the break times for additional production of embryo on donor were needed more than over 6 months after $1^{st}$ period OPU-IVP. This repeating uses of elite donor cows given more emphasis for getting the opportunity on mass production of elite cow OPU-IVP embryo should be increased G1+G2 possibility of genetic improvement of livestock within short period.
