1976년에 제정된 미국의 외국주권면제법은 외국정부의 주권적, 공법적 행위에 대해서는 미국법원은 원칙적으로 재판관할이 없음을 표명하면서, 예외적으로 그 외 국정부의 행위가 해당 주권면제법에서 규정하는 예외(exception)에 해당할 경우, 미국법원의 외국정부에 대한 재판관할을 인정한다. 특히“테러행위 예외(terrorism exception)”규정은 1996년에 외국주권면제법에 처음으로 추가되었으며, 외국 정부가 테러행위를 지원하여, 미국의 국무부로부터 “테러지원국”으로 지정된 국가의 경우, 해당 테러행위로 인해 신체적, 정신적 손해 를 입은 피해자들은 해당 테러지원국에 대해 민사상 책임을 묻는 민사소송을 미국 법원에서 제기할 수 있다. 본 논문에서는 외국주권면제법 상의 테러행위 예외 규정과 1996년 제정 이후 개 정된 내용을 살펴보고, 법원에서 관련 내용을 어떻게 적용했는지를 검토한다. 특히 테러행위 예외규정을 해당 규정이 제정 또는 개정되기 이전의 테러행위에도 소급 적으로 적용할 수 있는지? 피해자들에게 징벌적 손해배상도 부여할 수 있는지? 또 한 미국법원에서 테러지원국의 민사상 손해배상 판결을 획득한 피해자들이 테러지 원국의 재산을 압류 또는 집행할 때의 문제점 등을 거론한 판례도 살펴본다. 추가 적으로 북한에 대해 테러행위 예외를 적용하여, 북한의 재산을 압류, 집행한 오토 웜비어(Otto Warmbier) 관련 판결, 이란의 미국 내 재산압류에 대한 미국 판결 등을 분석한다.

This study aims to identify the effects of extracorporeal shock wave therapy and stretching technique on flexibility, muscle tone and pressure pain threshold of a shortened hamstring. A total of 40 patients with hamstring shortening was randomly assigned to either the extracorporeal shock wave therapy group (n=20) or extracorporeal shock wave therapy with stretching technique group (n=20) to identify the effects of the two different forms of physical therapy intervention. All the participants underwent extracorporeal shockwave therapy twice a week for 3 weeks, and the extracorporeal shockwave therapy with stretching technique group performed stretching techniques with the same frequency for 3 weeks. To measure hamstring flexibility before and after intervention, the passive straight leg raising test was performed, and muscle tone and pressure pain threshold were assessed. The flexibility of the hamstrings significantly improved, while the pressure pain threshold increased in both groups. These findings suggest that the effective in improving hamstring flexibility, reducing muscle tone, and increasing pressure pain threshold in adults with hamstring shortening.

Mitral valvular prolapse (MVP) in dogs is characterized by myxomatous valvular degeneration, which is caused by abnormal valvular thickening and incomplete coaptation of the mitral valve leading to mitral regurgitation. Mitral regurgitation causes left atrial and left ventricular enlargement. Pathogenesis of the disease is unknown, although some studies have suggested the involvement of endothelin and systemic connective tissue diseases. Mitral valvular prolapse in dogs commonly occurs in aged small dog breeds, including Malteses and Shih Zhus. This case study investigated the clinical features of an affected Maltese family and performed pedigree analysis. To the best of the authors’ knowledge, this is the first report of putative familial mitral valve prolapse and regurgitation in Maltese dogs. All family members in this study showed degenerative valvular changes and echocardiographic features of mitral valvular prolapse. Although disease progression differed, all dogs progressed to advanced heart failure stage within 2-3 years after diagnosis. Therefore, this is the first study to identify putative familial mitral valve prolapse in Maltese dogs. This finding suggests strong genetic etiology involved in the development of degenerative mitral valve disease in Maltese dogs. Furthermore, this finding could be a valuable resource for the identification of gene mutations in dogs with familial mitral valvular prolapse.

The nitric oxide(NO) is a major factor contri buting to t he loss of neurons in ischemic st roke. demyelina t ing diseases, and other neurodegenerative di sorders . But it is known that NO is not function ing as a direct neurotoxin. NO combined with superoxide(02-) by the diffusion-contl'O ll ed reaction, formed a peroxin it ri te anion (ONOO-)‘ which this s pecies has been shown to contribute to oxidative s igna ling and damage. ONOO stimuJates apoptosis in many cell types. whether ONOO acts direct ly as an ox idant 0 1' the induction of apoptosis is because of the radicals derived from ONOO- decompositi on . But. the mecha ni sm by which ONOO- induces apoptosis is un clear although subsequent forrnation 0 1' reactive oxygen s pecies(ROS) has been suggested in a few reports The aim of this study is to investigate the a nti -apoptotic pathway by inhibi tion 0 1' ONOO synthesis t hrough scavenging of ROS us ing s pecific wavelength 0 1' light irradiation . The present study investi gated the a nti -apop totic effect of the specific wavelength 0 1' irradi ation in Sodium Nitroprusside(SNP) t reated SJ-I-SY5Y ceJls, by MTT, DNA fragmentation, and flow cytometric assay and th rough western blot and caspase-3, -9 activity assay for confirmation of caspase pathway. Also. NO reJease and ROS leveJ was measured in order to observe the changes of NO involved in radical by Griess reaction analysis and DCF'-DH. Results showed that the cell viability were r educed by about 50% of control group by SNP treatment, but re covered to about 80% by 590nm irradiation . The apoptotic cells were observed by flow cytomet ry and DNA fra g mentation assay in SNP-treated group‘ but 590nm irradiation led apoptotic feature to be reduced . Released NO a nd ROS level were increased after SNP treatment but ROS level was dec reased in 590nm irradi at ion - treated group, in spite of high NO concentration fo llowing SNP treatment Also. SNP t reatment led cytochrom C release but 590nm irraidiation inhibit it, hence the expression 0 1' caspase-3 and -9 was dec reased sign ificantly‘ These results showed that 590nm irradiation protect neuronal death thl'Ough bl ocking of NO-induced mi tochondri al apoptotic pathway. Also, it suggests that specific wavelength of irradi ation was used for prevent ion from neurodegenerative disordcr progression

It has been reported that light-emitting diodes(LED) can be used in the treatment of oral diseases. Although bio-stimulatory effects of LED irradiation such as promotes stimulation of wound healing have been well known, there are few reports about molecular mechanism associated with cell cycle by LED irradiation. The purpose of present study was to examine the molecular event in cell cycle of LED irradiation on primary human gingival fibroblast(hGF) in vitro. The source of light for irradiation was a continuous-wave LED emitting at a wavelength of 635nm, and manufactured that energy density was 5mW/cm2 on sample surface. The hGF were irradiated for 1 hour at 37℃ in 5% CO2 humidified chamber. Experimental samples were acquired at 0 (right after irradiation), 8 and 24 hour after irradiation. To investigate the molecular mechanisms associated with cell cycle, growth phase was determined by flow cytometry and mRNA expression of cyclin A, cyclin B, cyclin D1, cyclin E, cdc2, PCNA, p18, p27, p21, and p53 were determined by real time RT-PCR. Flow cytometric analysis demonstrated the percentage of cells in the G1 and S phase were decreased, but the G2 phase increased, which showed cells irradiated by LED were transitioned from S to G2 phase. For mRNA expression, cyclin B, cdc2, PCNA and p53 were increased at 0 hour after irradiation, and most of cell cycle molecules were increased at 8 hour after irradiation. At 24 hour after irradiation, cyclin A, cyclin E, PCNA and p18 were increased. Taken together, LED irradiation induced proliferation of hGF cells through transition from S to G2 phase.

The purpose 01' pl'esent study was to examine the molecular events in apoptosis by CoCl2, mimicking hypoxic cond ition and recovering effects by LED ir l'adiation on Human SH-SY5Y neuroblastoma cells The SOUl'ce 0 1' light for ir l'adiation was a continuous-wave LED emitting at a wavelenl양h of 590 nm, and manufactured that ene rgy density was 5 mW!cm2 on sample surface, After ir l'adiation, cell viabi lity was measured with BrdU , cell morphol ogy was examined with Diff- Quik staining, cell signaling was monitored with various apoptosis-related molecules using RNase Pl'otection Assay(RPA) , W11en treated with CoC12, apoptotic induction was found in the SH-SY5Y cells in a concentration-dependent and time-dependent manner , Diff-Quik s taining was revealed that DNA fragmentation re presented apoptosis was examined in CoC12-tl'eated group, Moreover, RPA assay of SH-SY5Y cclls lIs ing val'iolls apoptosis-related molecllles showed that the apoptotic cell population was mcreased J-loweve. there was sorne signifïcant change in LED irradiatied cells aftel' treatement of CoC12 The main mechanism for Lhese a poptosis appearecl to be mito c hondriεt - m ecliated pathway, such as cytochrome- c‘ caspase-9, caspase-3, pro-apototic protein ßax, anti-apototic protein Bcl-2, and death receptor• mediated pathway, such as Fas, cas pase- 8, a ncl TNFRl These results demonstrate that CoCI2 induce apoptosis in SH-SY5Y via different dual apop tosis pathway through death receptor pathway as well as mitochondria- dependent pathway and LED irradiation can recl llces the CoCl2-induced apoptosis by blocking their internal signaling pathway

μ방lt emitting diodes (LED) devices are commercially introduced as an alternative for low-Ievellaser therapy (11ι，T) ， and it has several advantages over lasers such as a safe, efficient, and less-expensive altemative to treat wounds. And LED irradiation at the same biostimulatory wavelength has similar bíochemical effεαs. In the present study, to asses whether the I핑ht-emitting diode (LED) irradíation can stimulate bone regeneration, irradiated bony defects with or without grafting materials on rat calvaria were compared to corresponding nonirradiated control. Fifty male Sprague-Dawly rats weighing about 150g, were used. Factors for present study were designed as follows, 1) presence or absence of grafting materials, 2) with or without irradiation, and 3) number of irradiation. Two weeks after operation, rats were sacrifìced. Radiologic and 비stomorphologic fmdings were evaluated. Macrospically, there were no incidents of infection, dehiscence, hematoma and necrosis during study. Radiological findings showed greater radiopacity in the graft group and radiopacity increased as the number of irradiation increase. And microscopically, new bαle formation was great in the graft group and increased as the number of irradiation increase, Present study has shown that LED irradiation improved bone regeneration through radiologic and histomorphologic fmdings in rat.

Heading time is important element for yield and quality in crops. Among day length and temperature which influence on heading, temperature effect has not been investigated well. To investigate temperature effect on heading, heading date and plant growth characters were checked under the low and high temperature conditions in short day length. Analyzing heading date of six Korean varieties under the high and low temperature condition, heading date of varieties were delayed under low temperature. In the low temperature condition, dry weight and area of leaf were reduced. Varieties showing more delay of heading under low temperature also showed more reduction in leaf area. After selecting three varieties showing significant difference in leaf growth and heading date under different temperature conditions, nutrient contents of plant were analyzed. Nitrogen content was reduced in leaf and shoot under the low temperature condition. OsNRT2.3, nitrate transporter, was significantly down regulated in varieties showing more heading delay. Available phosphate content was decreased in leaf, but increased in shoot due to reduction of phosphate mobility. OsPT1, phosphate transporter regulating phosphate uptake, was more down regulated in varieties showing more heading delay. OsPT6, phosphate transporter regulating phosphate transport in plant, was also significantly down regulated in those varieties. With these data, we expected that active nitrogen and available phosphate uptake and transport in plant would increase leaf growth then might reduce heading delay under the low temperature condition.

Freesia is one of the most popular flowers over the world including Korea, due to the fragrance and beauty of the plant flower. The first domestic freesia cultivar ‘Shiny Gold’ was developed by NIHHS, RDA, in 2003, which has yellow double and large petals and strong fragrance. Ten years have passed since ‘Shiny Gold’ was cultivated at floral farms, and the deterioration of cut flower quality and yield are reported from the farms. Virus infection causes a reduction in the quantity and quality of the cut freesia flowers and is one of the most serious problems in Korea. Virus detection was carried by reverse transcription polymer chain reaction (RT-PCR) for FreMV, FreSV, BYMV, CMV, and TRV, as known to infect freesia. FreMV, FreSV, BYMV, and TRV were detected single or multiply, and CMV was not found in the freesia leaves collected from the farms. To produce virus-free freesia, meristem culture of ‘Shiny Gold’ was conducted in MS medium added ribavirin at different concentration. As the increased of ribavirin concentration, the growth of ‘Shiny Gold’ plantlets was inhibited in freesia’Shiny Gold’. The plantlets produced by meristem culture in ‘Shiny Gold’ were virus free at the enzyme-linked immunosorbent assay (ELISA) level.
