LRT is eco-friendly transportation system and can be constructed at less than half cost of subway. Therefore many local governments have planned to construct a various type of LRT and some of them were already under construction. In Para. 2 of Art. 22 of the "Enforcement Decree of Urban Railroad Act" - safety standard of urban railroad vehicle, It can't be operated if "structures and devices" don't come up to standard required to safety operation. Constructor or operator should give an order or operate according to safety standard in Art. 3 of the Safety Standard of Urban Railroad Vehicle. Safety Standard of Urban Railroad Vehicle of 2000 was reformed once to tighten fire safety standard in 2004 after subway accident in Daegue. It was entirely made for medium and large-sized electric motor car. LRT, based on driverless operation and articulated bogie, has different safety standard in signalling devices and the axle load. etc. So many institutes related LRT have required to amend. In this paper, we described features of LRT vehicle and necessity of amendment and discussed how it should be amended.

Queen Myeongseong was the wife of King Hyeonjong, the 18th king of the Joseon Dynasty, and the mother of King Sukjong. The clinical records of Queen Myeongseong are summarized on the basis of the Seungjeongwon Ilgi (The Daily Records of Royal Secretariat of Joseon Dynasty 承政院日記) and reviewed through Donguibogam. Queen Myeongseong gave birth to one male and three female children in the time of the queen. She took Geumgaedangguihwan (金櫃當歸丸), Dalsaengsan (達生散), Antaeum (安胎飮) during her pregnancy and Gungguitang (芎歸湯) during postnatal care. Since 1669, chest tightness, sleeplessness, arm pain and numbness of arms had been appeared. Ondamtang (溫膽湯) and Dodamtang (導痰湯) were used but they were not effective. However, when her symptoms were regarded as a benign tumor due to cold and wetness, there was a difference in the use of Ohjuksan (五積散). In 1683, when king Sukjong was caught in a smallpox, she took care of him. She exorcised in the middle of winter to pray for her son's recovery, and died of the flu.

Previous secure routing protocols for wireless sensor networks assume that a sink is static. In many cases, however, a sink operated by man or vehicle is moving. A mobile sink creates a lot of technical problems such as reconfiguration of routing path exposure of sink location. and selection of secure access point node, which are not considered by many previous researches. In this paper, we propose a new secure routing scheme for solving such problems using hi-directional hash chain and delegation nodes of grid structure. This scheme provides a secure routing path and prevents attacker from recognizing the location of a mobile sink in sensor networks. This new method reduces the resource requirements compared to the cashed routing schemes. Simulation results also show that the system is secure and efficient enough.

${\ll}$Gup Yu Bang${\gg}$ is the first korean book that specialized in pediatrics. It was written by Jo Jeong-jun in 1869 and contains 87 medical records. Medical records is one of the best way to develop one’s abilities of curing a disease without clinical practice and understanding medical condition of the time. These days we are fully aware of the importance of medical records, but there is no sufficient paper or study on medical records. On this study, we investigate 87 medical record of ${\ll}$Gup Yu Bang${\gg}$ by statistical methods. It was analyzed on the base of items such as age, sex, disease, method of medical treatment, treating prescription, modified medicinal substance, progress of disease. ${\ll}$Gup Yu Bang${\gg}$ contain 87 medical records and among of them, 84 records were Jo Jeong-jun own writings of clinical case. Systemic division of disease showed the highest in digestive disease and most frequent case was symptom of vomiting and diarrhea. The distribution of age was showed the highest in the age group under 5 years and the number of male case was more than female case. It showed that he considered observation of the patient's expression in diagnosis methods and have used 87 kinds of treating prescription and the external treatment, acupuncture, moxa. It showed that he quoted a lot of treating prescription from ${\ll}$Dong eui bo gam${\gg}$, ${\ll}$Yi-Hak-Yip-Mun${\gg}$ and ${\ll}$Xiao Er Yao Zheang Zhi Jue${\gg}$. The further study on medical records in traditional medical literatures, would reveal the developmental progress of Korean pediatrics and inform more actual proof on medical condition of the time.

Indium Antimonide(InSb)는 $3{\sim}5\;{\mu}m$대 적외선 감지영역에서 기존 HgCdTe(MCT)를 대체할 물질로 각광받고 있다. 1970년대부터군사적 용도로 미국, 이스라엘 등 일부 선진국에서 연구되기 시작했으며,이온주입, MOCVD, MBE 등 다양한 공정을 통해 제작되어 왔다. InSb 적외선 감지소자는 $3{\sim}5{\mu}m$대에서 HgCdTe와 성능은 대등한데 반해, 기판의 대면적화와 저렴한 가격, 우주공간 및 야전에서 소자 동작의안정성 등으로 InSb적외선 감지기는 냉각형 고성능 적외선 감지영역에서 HgCdTe를 대체해 가고 있다. 하지만 InSb는 77 K에서 0.225eV의 작은 밴드갭을 갖고 있기 때문에 누설전류로 인한 성능저하가 고질적인문제로 대두되었고, 이를 해결하기 위한 고품질 절연막 연구가 InSb적외선 수광 소자 연구의 주요이슈 중 하나가 되어왔다. 그 동안 PECVD, photo-CVD, anodic oxidation 등의 공정을 이용하여 $SiO_2$, $Si_3N_4$, 양극산화막(anodic oxide) 등 다양한 절연막에 대한 연구가 진행되었고[1,2], 절연막과 반도체 사이 계면에서의 열확산을 억제하여 계면트랩밀도를 최소화하기 위한 공정개발이 이루어졌다[3]. 하지만 InSb 적외선 감지기술은 국방 및 우주개발의 핵심기술중 하나로 그 기술의 이전이 엄격히 통제되고 있으며, 현재도 미국과 이스라엘, 일본, 영국 등 일부 선진국 만이 기술을 확보하고 있고, 국내의 경우 연구가 매우 취약한 실정이다. 따라서 본 연구에서는 InSb 적외선 감지기의 암전류를 제어하기 위한 낮은 계면트랩밀도를 갖는 절연막 증착 공정을 찾고자 하였다. 본 연구에서는 n형 (100) InSb 기판 ($n=0.2{\sim}0.85{\times}10^{15}cm^{-3}$ @ 77K)에 PECVD를 이용하여 $SiO_2$, $Si_3N_4$ 등을 증착하고 절연막으로서 이들의 특성을 비교 분석하였다. $SiO_2$는 160, 200, $240^{\circ}C$에서 $Si_3N_4$는 200, $300^{\circ}C$에서 증착하였다. Atomic Force Microscopy(AFM) 사진으로 확인한 결과, 모든 샘플에서표면거칠기가 ~2 nm의 평탄한 박막을 얻을 수 있었다. Capacitance-Voltage 측정(77K)을 통해 절연막 특성을 평가하였다. $SiO_2$와 $Si_3N_4$ 모두에서 온도가 증가할수록 벌크트랩밀도가 감소하는 경향을 볼 수 있었는데, 이는 고온에서 증착할 수록 박막 내의 결함이 감소했음을 의미한다. 반면계면트랩밀도는 온도가 증가함에 따라, 1011 eV-1cm-2 대에서 $10^{12}eV^{-1}cm^{-2}$ 대로 증가하였는데, 이는 고온에서 증착할 수 록 InSb 표면에서의 결함은 증가하였음을의미한다. 암전류에 큰 영향을 주는 것은 계면트랩밀도 이므로, $SiO_2$와 $Si_3N_4$ 모두 $200^{\circ}C$이하의 저온에서 증착시켜야 함을 확인할 수 있었다.

Thirteen patients received a coralline hydroxyapatite sphere as a buried integrated ocular implant after enucleation surgery. The implant was modified by multiple drillings, 1 mm in diameter, to the center of the sphere to allow more rapid host tissue ingrowth. $^{99m}Tc$-MDP planar and tomographic bone scintigraphies were performed at various intervals after implantation (from 100 to 742 days after operation) to assess vascularization of the implant. All patients showed hot uptakes in the implants. These patients underwent a secondary drilling for the final motility peg application. The confirmation of vascular ingrowth was done by inspection of bleeding at the time of bleeding at the time of drilling from the center of the implant. Bleeding from the drilled implant was noted in all patients. In cnclusion, hot uptake in the implanted ocular hydroxyapatite implant accurately reflect vascular ingrowth into the implant.

Background: The recent outbreak of the novel strain of influenza A (H1N1) virus has raised a global concern of the future risk of pandemic. Traditional Korean Medicine(TKM) has been combatting against contagious diseases and developed its own particular and efficient way in treating those diseases. Objectives: Provide a distinctive and effective TKM method in understanding the principles of treatment, prevention, and contraindications against influenza A through case histories. Method: We revised case histories of eminent doctors of Ming and Qing dynasties according to their clinical manifestations similar to those of influenza A. We also verified prescriptions of the "Dong-uibogam(東醫寶鑑)" through examining clinical practices of China today. Results: 1. The subtypes of Warm disease; Wind Warmth and Pestilence has the most similar clinical manifestation in comparison to Influenza A. Specifying these terms is important in recognizing and classifying various diseases under the name of Warm disease. 2. TKM considered not only external factors but also individual factors like general condition, diet, emotion, constitutional types, etc in the treatment of febrile diseases. 3. TKM developed a new way in the treatment of contagious diseases. considering the characteristics of each pathogen. TKM described the Warm pathogen being light as a feather, which enters through the nose, principally affecting the Lung. Therefore, they emphasized treatment with Pungent Sweet Cooling Moistening[辛甘凉潤] method. 4. As the conservation of fluid and humor is the primordial concern in the treatment of Warm disease, they restricted release of the exterior with pungent-warm and purgation method. The purgation methods was used exclusively to decrease fever and preserve fluid and humor. 5. The only differentiating characteristics of Influenza A with seasonal influenza are vomiting and diarrhea. Case research revealed the possibility of these manifestations to be a mechanism of restoration. 6. TKM provides alimento prevention method like Mint Pear Porridge, mung bean, and etc also combination of herbal medicine. Also emphasized in the conservation of essence for the prevention of contagious diseases. Conclusions: TKM developed its unique way in understanding the pathogenesis, diagnosis, treatment, and prevention of contagious diseases and formed its independent scheme of Warm Disease. This knowledge in febrile contagious disease is relevant today in providing diverse treatment and prevention for influenza A.

Developed countries have been taking their private security industry to the next advanced level to maintain safety of society, promote cooperative security in conjunction with public security such as the police, cultivate domestic security industry, and spur economic growth. In Korea, Service Security Business Act(currently, Security Business Act) enacted in 1976 laid groundwork for rapid institutional development. Nonetheless, the need to rename current title of Security Business Act has been discussed continuously among scholars and industry. Particularly, a bill(bill no.: 2389) was proposed in 2012 to rename 'Security Business Act' completely to 'Private Security Industry Act'. Under those circumstances, this study was intended to discuss proposals that had been made to rename the Act for underpinning development of security industry, along with its amendment, by gathering opinions from scholars in the field of security. It is undeniable that there is need for renaming the Act. As the renaming of the Act can have positive impact in many aspects for promotion of security industry, the urgency to rename the Act is indisputable. The results suggested that scholars specializing in security hoped the Security Business Act to be renamed primarily to Guard and Security Industry, and if not, to be renamed to Security Industry Act. The renaming of the Act will give rise to the need to amend many parts of provisions contained therein as follow-up action.

Objects : In the present study, we translated Mingyi-leian into modern Korean, and studied the medical records about the disease induced by emotional problem and the psychotherapy in Mingyi-leian for find the possibility of application that established researches did not studied. Methods : It was 197 cases that related to psychotherapy and emotional problem called Seven Passions(七情). We studied these records by statistical methods. Results : The anger(怒) was the most numerous cause into classified to Seven Passions in 197 cases. In the order of frequency of emotional causes, it was worry(憂), surprise(驚), lust(思), fear(恐), sorrow(悲), joy(喜) that classified into Seven Passions. The most disease induced by emotional problem was internal trauma(內傷), 11 cases. There was very numerous diseases induced by emotional problem except internal trauma. In ratio of the sexes, it was 104 cases in female and 93 cases in male from 197 cases. But the number of all case records about male were more than about female in Mingyi-leian, so female ratio was two times to male ratio. Specially, the percentage of cases about disease due to anger high in female. In ratio of the Seven Passions, the anger was most frequent cause of diseases due to emotional problem in 197 cases, and mostly caused bleeder's diseases. In oral medical treatments, various prescriptions were used. On the whole, the ratio of prescriptions about venting grudges(解鬱) records are mostly application of compatibility and incompatibility with the and warmly strengthening(溫補) were high. Psychotherapeutic medical Five Elements(五行) relation. But it also has psychotherapeutic medical record made by detailed and correct analysis can equal to modern psychotherapy, it is worth refer to clinic. Conclusions : Mingyi-leian and its medical records about the disease induced by emotional problem and the psychotherapeutic records have sufficient meaning to not only modern neuropsychiatric physicians but also physicians of all medical fields to treat disease of this kind.
