Mission Computer performs important role both managing a whole system and dealing with a specific mission in avionics system. In general, the fault of SPOF(Single Point Of Failure) in unity system can lead to failure of whole system. It can cause a failure of a mission and also can threaten to the life of the pilot. So, in this paper, we design the HA(High-availability) system so that dealing with the failure. And we use HA software like Heartbeat, Fake, DRBD and Bonding to managing HA system.

본 논문에서는 Kinect 기반의 모니터 제어 기법을 설계하고 구현한다. 이 기법은 Kinect의 Joint 기능을 활용하여 신체의 구조를 인식하고 손과 머리의 Joint를 받아온다. Kinect의 카메라는 손 동작을 추적하여 Joint 신체 부위에 해당하는 Joint 값을 모니터의 좌표 값으로 변환함으로써 손 동작에 따라 마우스를 움직이는 기능을 구현한다. 그리고 파워포인트에서 사용하는 F5, Esc, Right, Left 키에 대하여 Joint의 좌표 값이 일정 범위를 초과하면 마우스 클릭 이벤트를 발생하도록 구현함으로써 파워포인트의 슬라이드 화면을 제어하는 기능을 구현한다.

This study examines the role of six species of microalgae, including Phaeodacylum tricrnutum (PT), Chaetoceros gracilis (CG), Nanochloris oculata (NO), Pavlova lutheri (PL), Chlorella ellipsoidae (CE), and Scendedemus obliquus (SO), on hair loss prevention and scalp improvement. To determine the effects of microalgae extracts on hair loss prevention and scalp improvement, antioxidant activity, cell proliferation in HaCaT cells and HFDPC cells, and the inhibition level of 5-alpha reductase activity were examined. In the study of antioxidant activity, the $EC_{50}$ values of DPPH anti-radical activities indicated that the SO, CG, and ST9 treatment groups demonstrate significant antioxidant activity. In the study of the hydroxyl radical scavenging activity, CG (6.6~42.1%), ST9 (26.0~44.0%), and SO (7.8~44.3%) demonstrated significant effects. Furthermore, SO promoted the proliferation of HaCaT cells and a human epidermal cell line during a 6-day treatment. In the study of the proliferation of HFDPC cells, a hair follicle dermal papilla cell line, CG, and SO significantly stimulated cell proliferation. Finally, PT, CG, and SO significantly inhibited 5-alpha reductase activity. These results suggest that among the six microalgae used in this study, CG and SO have antioxidant effects, induce cell proliferation, inhibit 5-alpha reductase activity, and can be used for hair loss prevention and scalp improvement.

Jeon-Kwang(癲狂) is a term of oriental medicine, corresponding to schizophrenia. In detail, Jeon-Kwang is divided into Jeon(癲) and Kwang(狂). The symptoms of Jeon have silence, cry and giggle alternately, muttering, and so on. And those of Kwang have quick-tempered, absurd remarks, slander, and so on. We expierenced a patient who was suffered from headache, auditory hallucination, insomnia, anxiety, delirium, memory impairment and, cognitive disorder. In this case, we gave a diagnosis of Jeon-Kwang(狂) and, treated the patient with acupuncture therapy and sa-ha(瀉下) therapy (Dangguiseunggi-tang, Hwangryunsasim-tang). Sa-ha therapy is an oriental medicine therapy about wha(火) syndrom such as constipation, hydrodipsomania, red face. After three weeks of oriental medicine treatment, the chief complaints were considerablely reduced. This suggested that sa-ha herbal treatment have an effect on psychopathy.

In present, most of metallic structures(gas pipeline, oil pipeline, water pipeline, etc) are running parallel with subway and power line in seoul. Moreover subway system and power line make a stray current due to electrical corrosion on metallic structures. The owner of metallic structures has a burden of responsibility for the protection of corrosion and the prevention against big accident such as gas explosion or soil pollution and so on. So, they have to measure and analyze the data about P/S(Pipe to Soil) potential, amplitude of stray current, point of source of stray current and so. In this paper, results of development about data logger apparatus for measurement stray current of subway and power line are presented.

Most of maritime metallic structures are adopted a CP(Cathodic Protection) System for protection of corrosion in advanced country. So, we had been developed a remote corrosion monitoring control system. And we want to know the characteristics of efficiency, reliability, durability and so on. On the view point of it, we have to test in real field. in terms of design, cathodic protection systems, corrosion monitoring systems and optimal corrosion control systems compare to general commercial products. So, these systems have being studied to improve their capability. In this paper, the result of field testing center design of intelligent cathodic protection system including anodes, a real-time wireless remote corrosion monitoring and corrosion control system are described in naval ports.

Review of literature on stomachache. According to investigated the pathology of a stomachache about all sorts of falling ill, I have been obtained following conclusions. 1. The cause of Ui Wan Tong are clod-wet-ui wan, sik juk, dam eum, a huy1 be made of gi bul soon (氣不順). 2. Pain of Je sang bu are called jung wan tong, dae bok tong, jung cho tong, cause are sik juk, han sa, chung juk. pain of je ha bu are called so bok tong, hache tong, soh bok tong, so bok are devided two part, one is so eum sin the other is gul eum gan, cause are jo gyul dae jang, yul gyu1 bang kwang, hyul gyul bang kwang, porak hu ect. 3. Pain of je bu are called je bok tong, hwan je e tong, so bok je ju tong, and cause are juk yu1, jo si, dam hwa. Pain of yang hyup bu are called yang hyup ha so bok tong, yang bang ge hyup tong, yang hup jisang tong, cause are ban gi,yang myung jo geom. According to above results, the patholosy of a stomach ache about the part of falling ill in a course of transformation on the epidemic fever comes into the viscera.

Studies were carried out to evaluate the effect of liquid pig manure on the production of Japanese millet, the chemical characteristics of pasture soil and leaching water. The study was undertaken from June to September 2005. Randomized complete block design was used to allot four treatments: T1 (no fertilizer), T2 (N : 200 kg/ha, p : 150 kg/ha, K : 150 kg/ha), T3 (liquid pig manure containing 1.7% DM 200 kg N/ha) and T4 (liquid pig manure containing 7.0% DM 200 kg N/ha). Leaching water was sampled at 21 August (1st time), 9 September (2nd time) and 26 September (3rd time), 2005, respectively. No significant differences in the dry matter yield of Japanese millet was found among the four treatments, whereas the plant lengths of Japanese millet were higher in the T2, T3 and T4 than in T1 (p<0.05). Nitrogen, P and K uptake of J. millet tended to be influenced by application of chemical fertilizer or 7.0% DM liquid pig manure compared with T1 or 1.8% DM liquid pig manure. The organic matter (OM) content of soil was higher in T2, T3 and T4 than in T1. Na content was highest in T3 among the four treatments. $NO_{3^-}N\;or\;NH_{4^-}N$ content in leaching was not different among the four treatments. $SO_4$ content in leaching water sampled in 1st time was high in T4, but in T3 from 3rd time (p<0.05). Cl, Mg and Na contents were high in leaching water sampled in the 1st time from T4, whereas high in those from T3 in 2nd or 3rd time. Results show that the application of a high DM liquid pig manure is not better for producing Japanese millet and improving the properties of pasture soil than a low DM liquid pig manure. However, the contents of $SO_4$, Cl, Mg and Na in leaching water sampled in 1st time were high in a high DM liquid pig manure.
