Objective : Rumenshiqin(儒門事親) was compiled by Zhang Zi Huo(張子和) of the Jin(金) Dynasty of China. He invented unique medical theory and treatment such as three excretive methods(perspiratory, vomitory and purgative therapy). The aim of this study was to make the best use of the therapeutic theory of Rumenshiqin(儒門事親) connected with pediatrics. Methods: We conducted literature search in detail for contents of Rumenshiqin(儒門事親) and reviewed various kinds of books. Results : Zhang Zi Huo(張子和) recognized that children had pure-yang bodies(純陽之體) and emphasized that children need to prevent heat-stagnation(鬱熱) and asthenic yin(損陰). He instructed that a principle of raising such as wearing thin clothes, eating fresh food, harboring little desire and little anger, and taking temperate medicine. He described that pathogenic factors were mistake of rearing, misuse of medicine, exogenous factor, and excessive emotion. Conclusion : According to the above results, it is concluded that his therapeutic theory should be used at present.

본 논문은 게임 산업의 시작을 열었던 아케이드 게임의 유형과 특징에 대한 것이다. 아케이드 게임기는 크게 '기계식 게임기', '전기 기계식 게임기', '비디오 아케이드 게임기'로 진화해왔다. 이러한 진화과정에서 아케이드 게임은 다른 게임 플랫폼과는 차별화되는 자신만의 특징을 갖게 된다. 그 특징은 '공간성', '시간성', '게임성의 원형', '단순한 인터페이스', '공연성'이다. 최근 아케이드 게임의 침체는 이러한 아케이드 게임만의 특징들이 다른 게임으로 전이되면서 차별성이 퇴색되었기 때문이다. 그 특징을 다시 발굴하여 강화시킨다면 다시 게이머들를 사로잡을 수 있는 아케이드 게임을 만들 수 있을 것이다.

This study presents a numerical simulation of sea water-exchange as a preliminary accessing tool of water quality in the protected shore behind a overtopped breakwater. The overtopped breakwater is taken into account for a safe swimming and beach protection. The overtopping rate is calculated by empirical models and the consequent currents, known as wave-induced currents, are calculated under the conditions of H.W.O.S.T and L.W.O.S.T. The rate of sea water exchange is used to evaluate the characteristics of sea water exchange and calculated through the simulation processes such as advective discharging through the outlets and random-walking diffusion of particles released within a basin. The numerical results show that the overtopped waves sufficiently improve the water exchange without healthless stagnation of contaminated mass and the consequent currents are not too strong for swimming.

In this research, theoretical study on empirical analysis method to estimate waterdrop's deformation by shock wave is presented. Flow field is calculated using theoretical and empirical relations. Waterdrop's deformation including movement, size, mass, and orientation is modeled using empirical relations derived from existing experimental data. Developed method is applied to specific flight examples with arbitrary flight speed and vehicle's configuration. The flight speed is assumed to Mach number of 2 and 4. The diameter of waterdrop is varied from 1 to 5 mm. Waterdrops along the stagnation line in front of hemispherical nose with the radius of 50 mm and around a cone-shaped side wall with the half angle of 20 degree are considered. It is found that the maximum diameter of the waterdrop is increased up to 2.77 times the initial diameter. The mass is conserved more than 66.7 %. In the case of a cone-shaped side wall, waterdrop's orientation angles defined from the flight direction when the Mach number is 2 and 4 are calculated as 33.0 and 25.6 degree, respectively.

This study has analyzed the convective heat transfer on the deck exposed to the high-temperature impingement exhausting from a VTOL vehicle. The heat flow of the impingement on the deck is modeled by the convection heat transfer. The convective heat flux generated by the hot impinging jet is investigated by using both convective heat transfer formulation and conjugate heat transfer formulation. Computational fluid dynamics(CFD) code was used to compute the heat flux distribution. The RANS equation and the k-e turbulence model were used to analyze the thermal flow of the impinging jet. The heat flux distribution near the stagnation zone obtained by the conjugate heat transfer analysis shows more reasonable than the convective heat transfer analysis.

In the literal study of anti-tumor effects of Jakeumjung. the results were as follows. 1. Jakeumjung is a traditional oriental medical prescription which is composed of Cremastare appeniculatae tuber, Euphorbiae pekinensis radix, Toosendan fructus, Chinensis galla, Moschus, Realgar and Cinnabaris. 2. Jakeumjung is applied to patients by administering or external application. When it is administered for patients, pertinent dose is 0.6~1.5g twice or three times per one day. When it is applied by external application, we melt it by water or vinegar and apply it to patients. 3. Effects of Jakeumjung are expelling toxin and pestilence, counteracting pathogen and relieving stagnation, detumescence and stopping pain. So it is used for detoxification from ancient. In recent, it is often used for cancer such as breast cancer, pancreatic cancer, epigastric cancer, acute leukemia, lymphoma, thymus cancer and skin cancer. 4. From the various experiments, Jakeumjung has been proved to have antifungal and antitumor effects. It inhibits and kills L7212, L1210 cells of leukemia. Especially, it acts in S stage of cell period. 5. Jakeumjung includes mineral medicines such as Realgar, Cinnabaris. So if we execute progressive study for anticancer effects and safety, the boundary of oriental medicine of using mineral medicines for cancer therapy will magnify in the future.

Vortex tube is a simple device which splits a compressed gas stream into a cold stream and a hot stream without any chemical reactions. The phenomena of energy separation taking place in a vortex tube has been investigated experimentally. Recently, vortex tube is widely used to local cooler of industrial equipments and air conditioner of special purpose. In this study, experimental study on vortex tube efficiency was performed with various cold end orifices and nozzles type. The experimental results indicate that there is an optimum diameter of cold end orifice and nozzle type for the best cooling performance. The variation of the maximum wall temperature along the vortex tube surface provides useful information about the location of the stagnation point of the flow field at the axis of the vortex tube. The similarity relation for the prediction of the temperature of the cold exit air was obtained.

The effects of concave hemispherical surface curvature on the local heat transfer from a turbulent round impinging jet were experimentally investigated. The liquid crystal transient method was used for these measurements. This method, which is a variation on the transient method, suddenly exposes a preheated wall to an impinging jet while video recording the response of liquid crystals for the measurement of the surface temperature. The Reynolds number ranges from Re=11,000 to 50,000, the nozzle-to- surface distance from L/d=2 to 10, and the surface curvature from D/d=6 to 12.The present results are also compared to those for the flat plate case. In the experiment, the local Nusselt numbers tend to increase in all regions with an increasing surface curvature. The maximum Nusselt number for all Reynolds numbers occurred at L/d .ident. 6 and a second maximum in the Nusselt number occurred at R/d .ident. 2 for both Re=23,000 and Re=50,000 in the case of L/d=2 and for Re=50,000 only in the case of L/d=4. Meanwhile, as the surface curvature increases, the value of the secondary maximum Nusselt number decreases. All the other cases exhibit monotonically decreasing values of the Nusselt number along the curved surface. The stagnation point Nusselt numbers are well correlated with Re, L/d, and D/d.

1. According to causes of attack and symptoms, tinnitus is divided into two categories; deficiency and excess. Causes of excess syndrome of tinnitus were wind fire in the liver and gallbladder, phlegm fire, blood stagnation, and heat in meridian system and the causes of deficiency syndrome of tinnitus were qi deficiency or blood deficiency after an illness or delivery, yin deficiency of liver and kidney, and deficiency of sea of the marrow. 2. Tinnitus was related to the vicera and bowels, especially to liver, gallbladder and urinary bladder. 3. In regard of method of treatment, tonify kidney, nourish heart, clear the liver and discharge heat are used according to visera and bowel theory. Clear phlegm and downbear fire are used for phlegm fire. Tonify spleen and kidney is used for ancestral vessel deficiency. Dispel wind and dissipate fire can be used according to theory of five elements' motion and six kinds of natural factors. 4. The basal meridian of acupuncture and moxibustion treatment were the channels of Shaoyang.. 5. Regarding neuropsychiatric aspect of tinnitus, sudden anger and depression of mind were the main mechanism of disease and liver fire was the main cause. The prescriptions for neuropsychiatric tinnitus were Dangguiyonghuehwan, and Yongdamsagantang.
