  • This report on the $T{\acute{o}}u\;f{\bar{e}}ng$ and Migraine comes to conclude, through the study of the Oriental- Western medical references, as follow; 1. First, $T{\acute{o}}u\;f{\bar{e}}ng$ and Migraine had some concurrencies that both the two symptoms have appeared severe and recurrent headache and more often to the female. 2 Many of them e.g. Sensory disturbance, Vertigo, Nausea, Vomiting, Tinnitus etc. in the prodrome and main symptom of $T{\acute{o}}u\;f{\bar{e}}ng$ and Migraine were identical, especially the symptom of the $f{\bar{e}}ng\;t{\acute{a}}n\;t{\acute{o}}u\;t{\grave{o}}ng$ was similar to the prodrome of the Migraine. We could find out the semilarity of the symptoms through that Migraine is proximately set in unilateral, and $Pi{\bar{a}}nT{\acute{o}}u\;f{\bar{e}}ng$ is so called alias $B{\grave{a}}n\;bi{\bar{a}}n\;t{\acute{o}}u\;t{\grave{o}}ng$. 3. The pathogeny of $T{\acute{o}}u\;f{\bar{e}}ng$ include the case of ‘$f{\bar{e}}ng\;xi{\acute{e}}\;r{\grave{u}}\;n{\bar{a}}o$’, the patient feeling weak condition, $T{\acute{a}}n,\;T{\acute{a}}nshi,\;T{\acute{a}}nhu{\breve{o}},\;Y{\grave{u}}q{\grave{i}}$, etc. and, ‘$t{\acute{a}}n\;zhu{\grave{o}}\;sh{\grave{a}}ng\;y{\acute{a}}o$’, ‘$G{\bar{a}}n\;y{\acute{a}}ng\;hu{\grave{a}}\;f{\bar{e}}ng$’. There were variable that $F{\bar{e}}ng,\;Xu{\grave{e}},\;F{\bar{e}}ngr{\grave{a}},\;F{\bar{e}}ngx{\bar{u}},\;Xu{\grave{e}}x{\bar{u}},\;Hu{\check{o}}$ in the left, and $t{\acute{a}}n,\;R{\grave{e}},\;t{\acute{a}}nr{\grave{e}},\;Qir{\acute{a}}$ in the right partial pathogeny. It was referred $Sh{\grave{a}}o\;y{\acute{a}}ng\;j{\bar{i}}ng$, $Ju{\acute{e}}\;y{\bar{i}}n\;j{\bar{i}}ng$, $Y{\acute{a}}ng\;m{\acute{i}}ng\;j{\bar{i}}ng$, $T{\grave{a}}i\;y{\acute{a}}ng\;j{\bar{i}}ng$ in connection with the Meridian system. And otherwise the primary cause of Migraine is still unknown to us. Heredity is probably important, but the mode of transmission is uncertain. Recently, the important assumption is the vasomotor change caused by vasoconstrictors like that norepinephrine, epinephrine, and serotonin etc.

  • Through the case study, we surveyed the performance of a CNC-T BAR system on irregular-shaped building construction project. By CNC T-BAR system, we mean a surface curvature control system has been used in aircraft and ship manufacturing by controlling entire surface points on shape. For the past 10 year, the number of irregularly-shaped building design and construction project has been increased, and also the studies on irregular-shaped construction methods have been conducted. However, the previous studies did not review on the performance of the CNC T-BAR system. We collected construction-completed cases in Korea, which applied the CNC T-BAR system, and we studied its performance by comparing with a segment system in terms of construction duration and its quality. The result shows that the CNC T-BAR system can shorten the construction duration comparing with segment-assembly system while maintaining high quality. The CNC T-BAR system is expected to apply on the more number of irregularly-shape building construction project.

  • This study investigated the relationship of clothing microclimate and physiological responses in order to examine the layering effects on the clothing microclimate as an index to predict clothing thermal insulation ($I_{cl}$). Experiments were conducted in a $15^{\circ}C$ environment on six physically active males. Increased clothing layers resulted in higher mean temperature inside the clothing ($\bar{T}_{cl}$) and $I_{cl}$. The $I_{cl}$ had a high correlation with: $\bar{T}_{cl}$ (r = 0.556), the difference between the innermost surface temperature and the outermost surface temperature at the chest (DST) (r = 0.549) and the temperature inside clothing at the abdomen (r = 0.478). $\bar{T}_{cl}$ had the highest correlation with the temperature inside clothing at the abdomen (r = 0.889). $\bar{T}_{cl}$ also had the highest correlation with $\bar{T}_{sk}$ (r = 0.860). The results showed that the relationship between $I_{cl}$ and $\bar{T}_{cl}$ was linear (p < .01). Thermal comfort had a negative correlation with $\bar{T}_{cl-thigh}$ (r=-0.411) and $\bar{T}_{cl}$ (r = -0.323) (p < .01.)

  • 원추형콘과 T-bar 관입시험기는 점토의 비배수전단강도를 측정하기 위해 널리 사용된다. 축소모형시험의 경우 소형관입시험기가 사용되어야 하지만 경험상관계수에 대해 발표된 자료가 부족하다. 본 연구에서는 소형콘과 소형T-bar 관입시험기의 경험상관계수를 도출하기 위한 시험시스템을 구축하였고, 카올린점토에 대하여 실험을 수행하였다. 직경 350mm의 강재원형챔버를 사용하여 4개의 모형지반을 조성하였고, 각 모형지반은 다른 선행압밀응력에서 압밀하여 비배수전단강도를 조절하였다. 경계면 효과, 관입속도, 직경 및 형상의 영향을 확인하기 위하여 다른 직경을 가진 두 직경의 소형콘(10mm, 16mm)과 직경 10mm T-bar를 이용하여 시험을 수행하였다. 또한 관입시험 후의 시편을 채취하여 비압밀비배수삼축시험을 수행하여 비배수전단강도로 결정하였다. 최종적으로 비배수전단강도와 관입시 선단저항력의 상관관계를 통해 경험상관계수를 산정하였다.

  • 비선택성 제초제인 bialaphos는 고등식물에 있어서 glutamine 합성을 억제하여 식물체를 고사 시키는 능력을 갖고 있다. 본 연구에서 acetylteansferase에 의해 encoding된 bialaphos 저항성 유전자(bar gene)는 세균(Pseudomonas sryngae pv tabaci)의 genomic DNA로부터 cloning된 것을 사용하였다. 수분시킨 담배의 화계에 일정한 시간별로 bar 유전자를 처리한 결과 수분 후 30-40시간 사이의 처리구 에서 형질전환 식물체가 가장 많이 얻어 졌다. 그러한 형질전환 식물체의 kanamycin과 bialaphos 저항성 형질은 자식후대(T$_1$, T$_2$)에 있어서도 우성형질로 유전되었으나 wild type의 담배는 상기의 약제를 처리 하였을때 전부 고사하였다. 그리고, T$_1$세대의 형질전환 식물체로부터 전 염색체 DNA를 추출하여 Southern 분석한 결과 bar 유전자가 식물의 염색체상에 안정하게 존재하는 것을 확인하였다. 이상의 결과로부터 담배의 수분, 수정 시기에 외부유전자인 bar를 화주에 처리함으로써 bialaphos 저항성 식물을 만들어낼 수 있었다.

  • Railroad, a superior mode of public transportation provides safe, efficient, speedy, comfortable and economical service, has fundamentally different characteristics from airplanes, ships and cars. Among the unique characteristics of a railroad is the fact that it operates on fixed track with multiple car trains. The subway system was first selected as the best solution to difficult automobile traffic conditions and environmental problems. Seoul subway no.1line (Jongno line) was opened for service on August 15, 1974. Seoul city has completed and now operates eight subway lines (286.7km) since 1974. At present the subways operate in Busan, Daegu and Incheon city, and are under construction in Gwangju and Daejeon city. The power source for subway trains has been electricity since 1896, and power supply systems are the third rail type and/or the catenary system. The typical catenary system is the rigid bar type. R-bar and T-bar are used in the rigid bar type of catenary system, and the two types of R-bar and T-bar are uesd in Korea also. R-bar is used only for AC 25kV power supply and T-bar for DC 1,500V. From 30 years of subway experience I would like to suggest the most economic catenary system to ensure of safety, reliability and expediency for the railway lines to be constructed and the forthcoming replacement due to the life cycle after studying and analysing the characteristics, advantages and disadvantages of R-bar and T-bar.

  • Let C[0, T] denote the space of continuous, real-valued functions on the interval [0, T] and let C0[0, T] be the space of functions x in C[0, T] with x(0) = 0. In this paper, we introduce a Banach algebra ${\bar{\mathcal{S}}}_{{\alpha},{\beta};{\varphi}}$ on C[0, T] and its equivalent space ${\bar{\mathcal{F}}}({\mathcal{H}}) $, a space of transforms of equivalence classes of measures, which generalizes Fresnel class 𝓕(𝓗), where 𝓗 is an appropriate real separable Hilbert space of functions on [0, T]. We also investigate their properties and derive an isomorphism between ${\bar{\mathcal{S}}}_{{\alpha},{\beta};{\varphi}}$ and ${\bar{\mathcal{F}}}({\mathcal{H}}) $. When C[0, T] is replaced by C0[0, T], ${\bar{\mathcal{F}}}({\mathcal{H}}) $ and ${\bar{\mathcal{S}}}_{{\alpha},{\beta};{\varphi}}$ reduce to 𝓕(𝓗) and Cameron-Storvick's Banach algebra 𝓢, respectively, which is the space of generalized Fourier-Stieltjes transforms of the complex-valued, finite Borel measures on L2[0, T].

  • 본 연구에서는 UV 폭로 및 동결융해 환경이 FRP Hybrid Bar의 인장거동 및 표면 열화에 미치는 영향을 평가하기 위해 FRP Hybrid Bar를 대상으로 UV 폭로 및 동결융해 시험을 실시하였다. FRP Hybrid Bar의 경우 UV 폭로 및 동결융해 180cycle 시험 전/후 외관적인 열화가 거의 발생하지 않았다. 또한 FRP Hybrid Bar의 주요 장점 중 하나인 인장경화특성은 동결융해 시험을 거친 이후에도 유지되었는데, 이는 UV 폭로시험을 거친 FRP Hybrid Bar에도 유효하게 평가되었다. UV 폭로시험을 거친 FRP Hybrid Bar는 일반 FRP Hybrid Bar와 거의 비슷한 인장거동을 나타내었으며, 동결융해 180cycle의 진행에도 불구하고 일반철근, FRP Hybrid Bar, UV 폭로를 거친 FRP Hybrid Bar의 인장거동은 큰 변화를 나타내지 않았다. 본 연구에서는 UV 폭로 및 동결융해 환경이 FRP Hybrid Bar의 외관 및 인장 특성에 큰 영향을 미치지 못하는 것으로 판단되지만, 충격에 따른 규사코팅의 박락은 콘크리트와의 부착력에 영향을 미치므로 이에 대한 고려가 필요하다.

  • To see both $Sh{\grave{u}}nq{\grave{i}}daot{\acute{a}}nt{\bar{a}}ng$(dissipate phlegm and promote vital energy circulation) and $Hu{\grave{a}}y{\bar{u}}t{\bar{a}}ng$(blood circulation and disperse blood stasis) influencing on thrombosis, contusion-hyperemia, and hyperlipidemia, at first we measured the density of FDP, the quantity of fibrinogen, prothrombin time, and the number of platelet of rat taken thrombosis by endotoxin. Secondly we measured the increase-rate of "paw swelling", the number of platelet, the quantity of fibrinogen, and prothrombin time of rat taken contusion-hyperemia. And then we measured the quantity of total cholesterol in serum and of H.D.L-cholesterol and of triglyceride and of phospholipid and of ${\beta}-lipoprotein$, its weight, and the variation of the quantity of electrolyte of rat taken hyperlipidemia by the oral-injection of choleserol. As a result, we can conclude as follows : 1. Out of the test of thrombosis, we can recognize not only the noticeable increae of the number of platelet and the quantity of fibrinogen, but also the noticeable decrease of prothrombin time and the density of FDP in case of $Sh{\grave{u}}nq{\grave{i}}daot{\acute{a}}nt{\bar{a}}ng$-injected rat and $Hu{\grave{a}}y{\bar{u}}t{\bar{a}}ng$-injected rat. 2. Out of the test of contusion-hyperemia, we can recognize not only the noticeable increase of the number of platelet and the quantity of fibrinogen, but also the noticeable decrease of prothrombin time and "increase-rate of paw swelling" in case of $Sh{\grave{u}}nq{\grave{i}}daot{\acute{a}}nt{\bar{a}}ng$-injected rat and $Hu{\grave{a}}y{\bar{u}}t{\bar{a}}ng$-injected rat. 3. Out of the test of hyperlipidemia, at first we can recognize that test rat's weight increased as close as that of normal rat. And we can recognize the noticeable decrease of the triglyceride and phospholipid and ${\beta}-lipoprotein$." Also, in case of the variation of electrolyte we can recognize the decrease of calcium and potassium in $Sh{\grave{u}}nq{\grave{i}}daot{\acute{a}}nt{\bar{a}}ng$-injected rat, and of sodium and magnesium in $Hu{\grave{a}}y{\bar{u}}t{\bar{a}}ng$-injected rat. Thus, as the above-mentioned, in covering thrombosis, contusion-hypermia, and hyperlipidemia, the effect of $Sh{\grave{u}}nq{\grave{i}}daot{\acute{a}}nt{\bar{a}}ng$ and $Hu{\grave{a}}y{\bar{u}}t{\bar{a}}ng$ can be recognized. Granting that $Hu{\grave{a}}y{\bar{u}}t{\bar{a}}ng$ reveals its effectiveness in thrombosis and contusion-hyperemia, and $Sh{\grave{u}}nq{\grave{i}}daot{\acute{a}}nt{\bar{a}}ng$ in hyperlipidemia, it can be inferred that contusion-hyperemia is like "model of blood stasis form" as thrombosis and hyperlipidemia "phlegm-retention diseases form", and both phlegm-retention and blood stasis have correlation each other.
