1957년에 서명된 로마조약(條約)을 처음 개정한 단일(單一)유럽법(法)이 1987년 7월 1일에 발효(發效)되었을 때 유럽공동체(共同體) 12개 회원국(會員國)들은 공동정책(共同政策)에 의거 상업(商業), 농업(農業), 운송(運送), 금융(金融) 및 기타 관련부분에 있어 단일역내시장(單一域內市場)을 형성하기로 약속했다. 물론 완전한 역내공동시장(域內共同市場)은 자유로운 운송시장(運送市場)을 전제로 한다. 따라서 EC조약(條約)은 모든 회원국(會員國)들이 서어비스의 자유에 근거하여 공동운송정책(共同運送政策)을 따를 것을 강제하고 있다. 항공운송(航空運送)에 있어서의 목표도 역시 다른 모든 경제활동의 목표와 마찬가지로 로마조약(條約)이 적용되는 공동운송정책(共同運送政策)의 일부를 구성하고 있다. 종합적인 공동체항공정책(共同體航空政策)의 작업에는 운임(運賃), 공급량(供給量), 시장진출(市場進出) 및 경쟁상(競爭上)의 일괄적인 자유화 조치 이상의 것을 내포하고 있다. 그것은 국가장벽으로 방해되지 않는 공동체(共同體)의 항공운송망(航空運送網)의 개발과 확장뿐만 아니라 경제(經濟), 안전(安全), 환경(環境) 및 사회적(社會的) 요인(要因)들 간에 합리적인 균형을 이루는 공동체항공운송정책(共同體航空運送政策)의 개발을 위한 공동항공운송정책(共同航空運送政策)의 공식화(公式化)를 요한다. 1987년의 항공(航空)에 관한 일괄입법조치, 1989년의 제 2 차 항공(航空)에 관한 일괄입법조치 및 1992년 이후로 예정된 제 3 차 일괄입법조치에 따라 EC는 초국가적(超國家的)인 항공운송(航空運送) 분야에 있어서의 개방적인 국제경쟁(國際競爭)을 본격적으로 추구하고 있다. 결국 이러한 일괄규칙은 EC와 제(第) 3 국(國)들간의 관계에 중대한 의미를 가지게 될 것이다. EC항공운송정책(航空運送政策)이 아시아 항공산업(航空産業)의 상업운선(商業運船)에 어떠한 영향을 미칠 것인가는 모든 아시아 국가들이 알아야 할 중요한 문제이다. 이론적으로 말해서, 역내공동체(域內共同體) 항공운송(航空運送)의 자유화는 아시아 국가들에 대한 치외법권적(治外法權的) 효과를 일으킬 수 있는 로마조약(條約)과 유럽사법재판소(司法裁判所)에 의해 형성된 원칙들에 필연적으로 영향을 미칠 것이다. 이와 관련하여 아시아 항공산업(航空産業)은 무차별원칙(無差別原則), 설립(設立)의 자유(自由), 서어비스의 자유(自由) 및 EEC 경쟁법(競爭法)과 같은 제(第) 3 국(國)의 국제항공운송에 영향을 미치는 일련의 새로운 원칙과 법률의 출현에 큰 관심을 갖고 있다. 실무적인 관점에서, 1992년 이후의 종합적인 공동체항공운송정책(共同體航空運送政策)의 작업에는 항공운화(航空運貨), 시장진출(市場進出), 제(第)3 및 제(第)4의 운륜자유권(運輪自由權), 복수지정(複數指定), 제(第)5의 자유(自由), 캐보타지(cabotage), 손상(損傷)(derogation), 공급량(供給量), 편수(便數), 불정기운항(不定期運航) 및 기타 부문항공기소음(部門航空機騷音), 최저(最低) 안전(安全) 및 사회적(社會的) 조치(措置), 항공종사자면허(航空從事者免許), 감항증명(堪航證明), 운항시간제도(運航時間制度), 컴퓨터 예약제도(豫約制度), 탑승거절보상의 공동최저기준(共同最低基準), 공중혼잡(空中混雜), 공항이착륙시간할당법(空港離着陸時間割當法), 공항시설(空港施設), 정부지원(政府支援 등). 이와 같은 모든 공동체항공운송정책(共同體航空運送政策)의 주요문제들은 아시아 항공산업(航空産業)에 여러 각도로 영향을 미치게 될 것이다. 위와 같은 문제들 가운데, 제(第) 3국(國) 항공사(航空社)들의 역내공동체(域內共同體) 항로(航路)의 접근, 공급량(供給量), 운임(運賃), 제(第)5의 자유(自由) 및 캐보타지가 아시아 항공산업(航空産業)에 관심이 큰 문제가 되고 있다. 아시아 항공사(航空社)들의 EEC시장(市場)에로의 상업운항(商業運航)이 다소 영향을 받게 될 것이다. 첫째, 복수(複數) 목적지(目的地) 문제이다. 둘째, 항공(航空)서어비스의 운임(運賃) 및 료솔(料率)문제이다. 셋째, 항공운송구역(航空運送區域)에서의 사업에 대한 경쟁원칙의 적용 문제이다. 넷째, 제(第)5 자유(自由) 운륜권(運輪權) 문제이다. 다섯째, 캐보타지(cabotage)문제이다. 끝으로, 유럽 항공사(航空社)들간의 합병(合倂)의 문제이다. 결론적으로 유럽공동체항공운송(共同體航空運送)의 자유화는 1993년까지 공동체(共同體) 역내(域內)와 역외(域外)의 항공운송법제(航空運送法制)의 현재의 모습을 극적으로 바꾸어 놓을 정도로 가속화(加速化)되고 있다. 한편 항공운송(航空運送)의 자유화(自由化)에 대한 EC의 제의는 대담하고 급진적이다. 반면에 그것이 아시아 항공산업(航空産業)에 미칠 영향 또한 중대하다. 의심할 여지없이 항공사(航空社)와 고객들의 이익면에서 EEC와 비(非)EEC국가들의 항공운송산업(航空運送産業)에서 더욱 경제적으로 경쟁적이 되도록 할 필요가 있다. 전세계 항공운송산업(航空運送産業) 운영(運營)의 대부분을 정부가 소유하거나 통제하는 것은 정말로 국제항공운송(國際航空運送)의 발전에 불필요한 장애를 일으킨다. 따라서 國內航空社와 전세계 항공사(航空社)들간의 이해관계의 조화를 협상하는 것이 중요하다. 아마도 아시아 항공사(航空社)들간의 지역적 협조가 미국(美國)뿐만 아니라 유럽으로 부터의 압력 증가에 대해 균형을 이루는 힘이 될 수 있을 것이다.

This study aimed to offer groundwork for grasp and evaluation of nutritional status and dietary fiber intake through 24-hr recall method among middle school students in Chungbuk area. In addition, this study attempted to develop food frequency questionnaire (FFQ) for dietary fiber intake. Average calorie intake per person a day was 2035.6 kcal for boys, and 1876.7 kcal for girls which were 75.4% and 93.8% of estimated energy requirement (EER), respectively. Percent estimated average requirements (%EAR) of calcium, iron and folate were the lowest showing 34.3%, 54.2%, 67.5% for boys and 36.6%, 59.2%, 64.4% for girls, respectively. Average dietary fiber intake per day was $17.6\pm5.3$ g for boys and $16.5\pm4.8$ g for girls which indicate 54.8% and 68.8% of adequate intake (AI), respectively. The main food sources of dietary fiber were polished rice and kimchi. The main food source groups were vegetables, cereals and their products were fruits, seaweeds in the order named, indicating 68.44% total dietary fiber intake from vegetables and cereals. From preliminary 39 food items, 19 food items were selected to derive the correlation coefficient of each food item between 24-hr recall and FFQ method. Correlation coefficient was increased from 0.71 to 0.78 with significant level of p<0.01 after adjustment of FFQ from 39 items to 19 items set. Percentage of classifying subjects into the same levels by food frequency questionnaire and 24-hr recall based on joints classification quartile Kappa value was evaluated. Agreement was highest in the second lowest group showing percentage to correspond rose from 90.2% to 92.4% and Kappa value of 0.54 to 0.59. Consequently, FFQ developed in this study would be useful for estimating the groups which show low intake.

A duplex RT-PCR (dRT-PCR) assay was developed for the simultaneous detection and discrimination of non-virulent and virulent Newcastle disease virus (NDV) in a single PCR tube. Primers targeting the large polymerase protein (L) gene and the fusion protein (F) gene of NDV were designed to detect all NDVs (by common type PCR primers) and virulent NDVs (by pathotype PCR primers), respectively and evaluated experimentally with reference NDV strains and other poultry viral pathogens. PCR products of the expected size of 386 bp were amplified from all NDV samples whereas PCR products of the expected size of 229 bp were amplified from virulent NDV samples alone. Cross reaction was not observed with other avian viral pathogens. The detection limit of NDV by the dRT-PCR was estimated to be $10^3$ 50% egg infectious dose/0.1 mL. In the dRT-PCR using field isolates of NDV, the pathotype PCR primers detected specifically all of virulent field isolates of NDV from Malaysia, Pakistan and China whereas common type PCR primers detected 94.4% (51/54) of field isolates of NDV from China. Three Chinese NDV isolates with false negative result were non-virulent viruses. Our results indicate that the dRT-PCR might provide a rapid and simple tool for rapid simultaneous detection and discrimination of non-virulent and virulent NDVs. Therefore the developed dRT-PCR assay provides a powerful novel means for the rapid diagnosis of Newcastle disease.

Objectives : Face-to-face interviews were conducted to investigate the relationship between blood pressure and the impairment of cognitive function in rural elderly (N=932) aged 60-64 in Dalsung County, April to September in 1996 Methods : Impairment of cognitive function was defined as a score of less than 23 by the Korean version of the Mini-Mental State Examination (MMSEK). Blood pressure was measured once in each subject using a portable automatic sphygmomanometer. Results : By univariate logistic regression on males, no category of systolic blood pressure bore statistical significance. Groups with diastolic blood pressures of, less than 80 mmHg, 90-94 mmHg, and more than 95mmHg had odds ratios of more than one compared with the reference group (80-89 mmHg). This was most significant in the group with blood pressures lower than 80 mmHg, which had a statistically significant odds ratio of 1.68 (95% confidence interval CI; 1.02-2.75). No category of blood pressure was statistically significant in females. Multivariate logistic regression for males, with adjustment for age, educational attainment, smoking, alcoholic drinking, body mass index, atherosclerotic disease, and antihypertensive medication use, did not alter the odds ratios significantly in terms of systolic blood pressure. However, the group with diastolic blood pressure of less than 80 mmHg had an increased odds ratio of 2.01 (95% CI; 1.15-3.52) compared with the reference group. In females, systolic blood pressure did not alter the odds ratio, but the group with a diastolic blood pressure of less than 80 mmHg had a statistically significant odds ratio of 0.57 (95% CI; 0.37-0.89). Conclusions : These results suggest that the relationship between blood pressure and cognitive function status is stronger diastolic than systolic blood pressure and that there is a complex relationship between blood pressure and cognitive function by sex.

We compared between an automated most-probable-number technique $TEMPO^{(R)}$TVC and traditional plating methods $Petrifilm^{TM}$ for estimating populations of total aerobic bacteria in various livestock products. 257 samples randomly selected in local retail stores and 87 samples inoculated with $E.$ $coli$ ATCC 25922, $Staphylococcus$ $aureus$ ATCC 12868 were tested in this study. The degree of agreement was estimated according to the CCFRA (Campden and Chorleywood Food Research Association Group) Guideline 29 and the agreement indicates the difference of two kinds methods is lower than 1 log base 10($log_{10}$). The samples of hams, jerky products, ground meat products, milks, ice creams, infant formulas, and egg heat formed products were showed above 95% in the agreement of methods. In contrast, proportion of agreement on meat extract products, cheeses and sausages were 93.1%, 92.1%, 89.1%, respectively. One press ham and five sausages containing spice and seasoning, two pork cutlets containing spice and bread crumbs, two meat extract product and two natural cheeses and one processing cheese with a high fat content, and one ice cream containing chocolate of all samples showed the discrepancy. Our result suggest that $TEMPO^{(R)}$TVC system is efficient to analyses total aerobic bacteria to compare manual method in time-consuming and laborious process except livestock products having limit of detection.

Most of significant ore deposits in South Korea such as the Sangdong W - Mo, the Yeonhwa Pb-Zn and the Geodo Cu-Fe skarn ore deposits occur at the southern limb of the Hambaeg syncline in the Taebaeg Basin. The mineralization took place in the interbedded limestone of the Myobong Formation and the Pungchon limestone of the Great Limestone Group of the Cambrian age, generally striking E-W and dipping 25-30 degrees north. There are no outcrops of the skarn-type orebody at the northern limb of the syncline. In order to find a clue of a possible hidden orebody localized at the limestones in the northern limb, a lithogeochemical exploration by using carbon isotope and some elements such as Si, Ca, Fe and Al at the Sangdong Mine area has been attempted as for a modelling study. For this study, 45 samples from the Pungchon limestone which do not show any megascopic indication of mineralization have been taken in both the mineralized zone and the unminerallized zone at the Sangdong Mine area. Analytical data show that there are big differences in the contents of CaO and $Al_2O_3$ between the Pungchon limestone of the mineralized zone and that of the unmineralized zone. Carbon isotope data exhibit that ${\delta}^{13}C$ values of the Pungchon limestone in the mineralized zone are highter than those in the unmineralized zone. The difference in the analytical values of CaO, $Al_2O_3$ and the carbon isotope between the mineralized and the unmineralized zones is as follows ; Unminerallized zone Mineralized zone CaO 51.3% 43.5% $Al_2O_3$ 0.6% 2.4% ${\delta}^{13}C$ -0.39 permil -0.56 permil $Fe_2O_3$ 0.9% 1.4% $SiO_2$ 3.0% 2.4% The decrease in the Si content of the Pungchon limestone in the mineralized zone is contrary to the result of the previous study (Moon, 1987). On the basis of identification of the increase in the Al content of the limestone in the mineralized zone, it could be deduced that the decrease in the Si content of the Pungchon limestone might be due to the result of increase in the alteration products mainly occurred along fracture-system such as joint cracks or minor faults and that the phenomena shown by the Si and Al content in the mineralized zone might be derived from the thermal effect of granite extended mineralizing activity to the overlied limestone on the surface. Higher mean values of Fe and Al as well as lower mean values of carbon content and the ${\delta}^{13}C$ than mean values of those in the Pungchon limestone at the northern limb of the Hambaeg Syncline may be applicable in exploration for blind orebodies.

This article surveys the current international law with respect to RPAS from both the public air law and private air law perspectives. It then reviews current and proposed Australian domestic RPAS regulation while emphasizing the peculiar risks in operation of RPAS; and how they affect concepts of liability, safety and privacy. While RPAS operations still constitute only a small portion of total operations within commercial aviation, international pilotless flight for commercial air transport remains a future reality. As the industry is developing so quickly the earlier the pursuit of the right policy solutions begins, the better the law will be able to cope with the technological realities when the inevitable risks manifest in accidents. The paper acknowledges that a domestic or regional approach to RPAS, typified by the legislative success of the Australian experience, is and continues to be the principal measure to deal with RPAS issues globally. Furthermore, safety remains the foremost factor in present and revised Australian RPAS regulation. This has an analogue to the international situation. Creating safety-related rules is imperative and must precede the creation or adoption of liability rules because the former mitigates the risk of accidents which trigger the application of the latter. The flipside of a lack of binding airworthiness standards for RPAS operators is potentially a strong argument that the liability regime (and particularly strict liability of operators) is unfair and unsuited to pilotless flight. The potential solutions the authors raise include the need for revised ICAO guidance and, in particular, SARPs with respect to RPAS air safety, airworthiness, and potentially liability issues for participants/passengers, and those on the ground. Such guidance could then be adapted swiftly for appropriate incorporation into domestic laws bypassing the need for or administrative burden and time it would take to activate the treaty process to deal with an arm of aviation that states know all too well is in need of safety regulation and monitoring.

Regulation (EC) No 261/2004 ("Regulation") is a common rule on compensation and assistance to passengers in the event of denied boarding and of cancellation or long delay of flights. In some recent cases of European nations, passengers sued the air carrier in order to obtain monetary compensation under Article 7(1) of the Regulation. Some courts dismissed the actions on the grounds that, unlike denied boarding or cancellation of the flight, the Regulation provides no compensation in relation to delayed flights. However, Court of Justice of the European Union(CJEU) ruled that Regulation 261/2004 must be interpreted to mean that passengers whose flights are delayed have a right to compensation in cases when the loss of time is equivalent to, or is in excess of three hours - where the passengers eventually reached their final destination three hours or more later than the originally scheduled arrival time. It is true that a strict interpretation of the regulation would suggest that passengers whose flight has merely been delayed are not entitled to compensation. They should only be offered assistance in accordance with the Articles 6 and 9. Nevertheless, the Court recognized the same right to the same compensation for passengers of flights delayed by more than three hours as that explicitly provided for passengers of cancelled flights. On the one hand, the Court bases this ruling on the recitals of the Regulation, in which the legislature links the question of compensation to that of a long delay, while indicating that the Regulations seek to ensure a high level of protection for passengers regardless of whether they are denied boarding or their flight is cancelled or delayed. On the other hand, the Court interprets the relevant provisions of the Regulation in light of the general principle of equal treatment. Furthermore, the Court delivered a ruling that the loss of time inherent in a flight delay, which constitutes an inconvenience within the intention of Regulation No 261/2004 and which cannot be categorized as 'damage occasioned by delay' within the meaning of Article 19 of the Montreal Convention, cannot come within the scope of Article 29 of that convention. Consequently, under this view, the obligation under Regulation No 261/2004 intended to compensate passengers whose flights are subject to a long delay is in line with Article 29 of the Montreal Convention. Although the above interpretation of the Court can be a analogical interpretation, the progressive attitude of the Regulation and the view of Court forward to protect passengers' interest is a leading role in the area of international air passenger transportation. Hopefully, after the model of the positive support in Europe, Korea can establish a concrete rule for protecting passengers' right and interest.

The current international legal system does not provide a safeguard against the militarization and the weaponization of outer space. Although the term "peaceful use of outer space" in the 1967 Outer Space Treaty(OST) appears in official government statements or in multilateral space treaties, it is still without an authoritative definition in reviewing national practices. The ambiguous ban on weapons in Article IV of the OST allows countries to loophole on the deployment of other weapons other than nuclear weapons. Meanwhile "Draft Treaty on the Prevention of the Placement of Weapon in Outer Space and of the Threat or Use of Force against Outer Space Objects(PPWT)" to Conference on Disarmament (CD) commissioned by the UN General Assembly's Special Session jointly submitted by China and Russia in 2008 and later revised in 2014, attempting to define and prohibit the proliferation of weapons in outer space and provided definitions of prohibited weapons, are opposed by the US on the grounds that currently there is no arms race in outer space. Some experts support a hard law approach in which binding laws aimed at ultimately creating integrated and binding legal instruments in all aspects of the use of outer space should be adopted to regulate the military use of space. However as a temporary measure the soft law guidelines should be developed for the non liquiet, a situation where there is no applicable law. The soft law could be used to create support for the declaration of the treaties and to create international customary law. For example, the 1963 Declaration of Legal Principles Governing the Activities of States in the Exploration and Use of Outer Space that regulates the activities of the state in the exploration and use of the universe, and the 1992 Principles Relevant to the Use of Nuclear Power Sources in Outer Space will illustrated. While substantial portions of the former was codified later in the 1967 OST, the latter which, although written in somewhat mandatory terms, have been consistently complied with by states, have arguably become part of customary international law. On November 12, 1974, the General Assembly reaffirmed that the development of international law may be reflected inter alia, by declarations and resolutions of the General Assembly which may to that extent be taken into consideration by the International Court of Justice.

The Born approximation is widely used for solving the complex scattering problems in electromagnetics. Approximating total internal electric field by the background field is reasonable for small material contrasts as long as scatterer is not too large and the frequency is not too high. However in many geophysical applications, moderate and high conductivity contrasts cause both real and imaginary part of internal electric field to differ greatly from background. In the extended Born approximation, which can improve the accuracy of Born approximation dramatically, the total electric field in the integral over the scattering volume is approximated by the background electric field projected to a depolarization tensor. The finite difference and elements methods are usually used in EM scattering problems with a 2D model and a 3D source, due to their capability for simulating complex subsurface conductivity distributions. The price paid for a 3D source is that many wavenumber domain solutions and their inverse Fourier transform must be computed. In these differential equation methods, all the area including homogeneous region should be discretized, which increases the number of nodes and matrix size. Therefore, the differential equation methods need a lot of computing time and large memory. In this study, EM modeling program for a 2D model and a 3D source is developed, which is based on the extended Born approximation. The solution is very fast and stable. Using the program, crosshole EM responses with a vertical magnetic dipole source are obtained and the results are compared with those of 3D integral equation solutions. The agreement between the integral equation solution and extended Born approximation is remarkable within the entire frequency range, but degrades with the increase of conductivity contrast between anomalous body and background medium. The extended Born approximation is accurate in the case conductivity contrast is lower than 1:10. Therefore, the location and conductivity of the anomalous body can be estimated effectively by the extended Born approximation although the quantitative estimate of conductivity is difficult for the case conductivity contrast is too high.
