NJOY 코드 씨스템으로 JEF-1 평가 핵자료를 처리하여 고속로용 50군 군정수 SET을 생산하였다. 이를 이용하여 스물일곱가지 고속 임계로심 실험에서 얻어진 임계도 및 노심 중앙에서의 반응 율비를 계산하고 측정치와 비교·분석하였다. 아울러 ENDF/B-IV와-V 자료로 해석한 결과와도 비교·검토하였다. 일반적으로, 임계실험의 적분량 추정에서 JEF-1의 결과는 지금까지 사용해온 ENDF/B-IV의 결과보다 개선되었고, ENDF/B-V의 결과에 근접하고 있다.

The import control provision of US MSA (Magnuson-Stevens Fishery Conservation and Management Act) IUU fishing is similar to that of MMPA (The Marine Mammal Protection Act of 1972 as Amended) which caused US-Tuna(1991) case. This paper examines whether MSA's import control provision can be found to be inconsistent with WTO agreement. There is no doubt that MSA violates the Article XI:1 of the GATT 1994. The only remaining issue is whether US IUU fishing product measure is justified by the Article XX(g) and its Chapeau. However, Article XX(g) provides for a limited and conditional exception from obligations under other provisions. This paper concludes that the US MSA measure can not be justified under Article XX.

The terrestrial impact cratering record recently has been examined in the time domain by Chang & Moon (2005). It was found that the ${\sim}26$ Myr periodicity in the impact cratering rate exists over the last ${\sim}250$ Myrs. Such a periodicity can be found regardless of the lower limit of the diameter up to D ${\sim}35km$. It immediately called pros and cons. The aim of this paper is two-fold: (1) to test if reported periodicities can be obtained with an independent method, (2) to see, as attempted earlier, if the phase is modulated. To achieve these goals we employ the time/frequency analysis and for the first time apply this method to the terrestrial impact cratering records. We have confirmed that without exceptions noticeable peaks appear around ${\sim}25$ Myr, corresponding to a frequency of ${\sim}0.04(Myr)^{-1}$. We also find periodicities in the data base including small impact craters, which are longer. Though the time/frequency analysis allows us to observe directly phase variations, we cannot find any indications of such changes. Instead, modes display slow variations of power in time. The time/frequency analysis shows a nonstationary behavior of the modes. The power can grow from just above the noise level and then decrease back to its initial level in a time of order of 10 Myrs.

Rather than just another "review," this is intended to be an "overview" of the entire subject of the medial sural artery perforator (MSAP) flap as has been presented in the reconstructive literature from its inception in 2001 until the present, with any exceptions not purposefully overlooked. Unfortunately, the pertinent anatomy of the MSAP flap is always anomalous like most other perforator flaps, and perhaps even more variable. No schematic exists to facilitate the identification of a dominant musculocutaneous perforator about which to design the flap, so some adjunctive technology may be highly valuable for this task. However, if a relatively thin free flap is desirable for a small or moderate sized defect that requires a long pedicle with larger caliber vessels, the MSAP flap deserves consideration. Indeed, for many, this has replaced the radial forearm flap such as for partial tongue reconstruction. Most consider the donor site deformity, even if only a conspicuous scar on the calf, to be a contraindication. Yet certainly if used as a local flap for the knee, popliteal fossa, or proximal leg, or as a free flap for the ipsilateral lower extremity where a significant recipient site deformity already exists, can anyone really object that this is not a legitimate indication? As with any perforator flap, advantages and disadvantages exist, which must be carefully perused before a decision to use the MSAP flap is made. Perhaps not a "workhorse" flap for general use throughout the body, the MSAP flap in general may often be a valuable alternative.

This thesis examines analyzing how historic knowledge was shaped in museum. Examining by Tokyo Imperial Museum, Government General Museum of Taiwan, Yi Wang Ga Museum, Government General Museum of Chosun, and NanTong Museum of late 19th and early 20th century, tried to find out similarities and differences. These museums are similar in that they adopt museums as modern system considering models of other countries(Europe or Japan) and exhibitions played important roles in gathering relics. Experts who leaded adoption of western civilization played an important role. These experts were conservatives who valued tradition and relics while they aimed for western civilization. It originated in the character of museum system. Historical Knowledge by museums was constituted with five combinations of conceptions which are nationality, locality, coloniality, and artistry. Every museum cannot help having modernity for museum itself is modern system. Modernity was symbolized by museum building of western style in Yi Wang Ga Museum, Government General Museum of Chosun. Tokyo Imperial Museum revealed nationality in that it tried building of imperial history which includes colonies. In early time, Tokyo Imperial Museum pursued modernity and artistry, however it concentrated on artistry than modernity later. We can find locality in that Tokyo Imperial Museum tried to find meaning about Japanese art by relating with natural characteristics. It is Taiwan Governor Museum that extremely expressed coloniality and artistry was not considered. Government General Museum of Chosun could not be exceptions of features of coloniality, but it need to recognize that artistry was focused all over the exhibitions. It was NanTong Museum that most directly expressed locality. Like these, Museums of East Asia established in around 1900 made different historical knowledge by varying weigh of five factors, nationality, locality, modernity, coloniality and artistry.

The information concerning epithelial dysplasia of the oral cavity has been relatively little published. Of the histolgic grades, most of the cases were classified as moderate and severe category. Their ages ranged from 27 to 78 years(mean 57 years). The developmental incidence by sex was superior in male by ratio of 6 : 1. Epithelial lesions were located in the buccal mucosa, Floor of the mouth, the gingiva and the tongue. It is generally believed with a few exceptions that mild degree of epithelial dysplasia do not indicate any great danger for the patient. But severs dysplasia indicates that there is a very considerable risR of malignant transformation. Surgical excision is the effective method of controlling epithelial dysplasia. The authors investigated 7 cases of epithelial dysplasia histopathologically, 2 patients of them had malignant transformation. We discuss the clinical feature, treatment, prognosis, and histopatholgic analysis with literature reviews.

This study concerns therapeutic effects and long-term effects of Therapy Dog Assisted Program (TDAP) on autistic children. Subjects participating in this study are two groups of Korean elementary school boys of the same age (twelve years old) : an experimental group and a controlled group of equal number of children (six children in total). The thirteen different sessions of the first intervention and eight different sessions of the second intervention were performed over six months (from April 20th to October 27th, 2000). Two standard instrument (ASIEP, E-CLAC) are used as major instruments in order to evaluate the effectiveness of TDAP. Evidene from the present study indicates that the children participating in TDAP program achieved a greater degree of improvement in their social interaction in comparison with the counterpart. The present study also demonstrates that, in general, the effectiveness of TDAP somewhat decreased after the termination of TDAP with some exceptions. However we also found that the effectiveness of TDAP were maintained in the some behavioral area such as bowing to teacher, play for cooperation with peers, which activities were sufficiently offered TDAP to the children. The questions of possible influence of parental support and other family background of each individual autistic child on the effect and long-term effect of TDAP need to be addressed in future study.

Purpose: The therapeutic process has various benefits since it relives most of the stresses that people are undergoing in their various working places. Thus this study will determine this process's impact on workers in their different working places. Most of the workers that are being affected by stress and use this technique are the nurses. Research design, data and methodology: The present research conducted the PRISMA process which are important in research as it provides information that individual studies cannot. Guided by a specific research question, systematic reviews collate empirical evidence that fits particular criteria to provide a summary of available evidence. Results: The findings of all fifteen investigations were reviewed, but those with the strongest evidence were given more weight. Observers should be aware that the findings on aromatherapy approaches for nurses and patients are so uniform that advice might apply to both in a high acuity workplace. Conclusions: This research concludes that with the exception of a few rare exceptions, aromatherapy is a very efficient and safe treatment that does not build up in the body, but instead is expelled via the lungs, liver and kidneys. Non-invasive aromatherapy immediately affects the brain, and anyone may give the treatment at any time or place, regardless of the location.
