This article aims to observe the role of Arabic and analyze the future of Arabic in France under the base of the Al-Sabhan Rabina Baldhawe's article, published in mettre l'importance sur University Paris 8 in 2007. In the first part, we have focus into the historical analysis: in France, with a few Arabic and French policy has been settled for what were examined. Also enable the use of Arabic in France with regard to trends of Maghreb countries and other Arab countries, is being led by noted. In the second part, we put on the importance about the situation of Arabic in the France's educational institution. And we have analysed the reasons why Arabic became the most important reason for learning the target language: - in order to faciliate the children of immigrants living in Maghreb able to speak French - Due to differences in culture and language experience to relieve the psychological insecurity above sea - By using the Arabic language at home among family members, strengthen solidarity and resolve heterogeneity In the third part, we have recognized that the French education system was looked at in the Journal of Arabic teaching elementary, middle and high school courses, separated by a learning Arabic as the target language. Finally, we have tried to find a way to revitalize Arabic in France in connection with Sabhan Rabina Al-Baldhawe concrete example of the paper were based on a survey. France and the Arab countries' relationship has been long enough to prove the historic aspects and economic cooperation have maintained a relationship even tighter. Arabic, many of the French people also need education and children to learn Arabic in the French educational institution that has shown a positive stance. French students learning Arabic as a future career in choosing the width of the wider benefits it helps to have. Learning Arabic in the course need to be addressed is also true that a lot of points. But the Arabic and various aspects of internal organization is considered a minority in the popular Arabic language training in France has become more competitive in research and analysis to be active stance is required externally, such as the increase of trade agreements and economic systems side at the level of cultural exchange and international co-operation system, strengthening its position as the Arabic language in France.

As for the methodology of physical science, on the one side, Ludwig Boltzmann was declined to Scientific Realist and at the same time Epistemological Idealist. But on the other. He was neither fully nor consistently either one of them, because of rejecting the causal realism of the former and the belief in absolute certainty of the latter. Is there nevertheless any evidence that he had a coherent world view of his own? Yes. In short, he seems to identify his own position with what is called a mind-matter identity theory. In 1897, he supported that psychological processes are identical with certain processes in the brain(realism). And in 1903, he said : "Physics is not separated from psychology. They are only different sides." But Boltzmann did not explain concretely the possibility of this identity. So I tried to construct one theory of identity which is suitable for understanding problems n the physical world, though whether it would work for a full-scale world view which includes both physical and mental phenomena remains problematic. If light phenomena, for example, tend to be measured in terms of some contexts as if light were a wave and in others as if light were a particle, then one may be able to reasonably suppose that light has whatever characteristics in itself which it must have in order to seem like a wave under some conditions of measurement and like a particle in others. If this theory is provisionally to mental phenomena as well, it would mean that reality has those characteristics in itself which it must have to appear as it does to the various faculties of the mind and as it is measured in different physical situations. This is probably not what Boltzmann meant by his theory of identity, since it is very ontological and metaphysical. But in my opinion it is by far the most reasonable identity theory.

In preclinical positron emisson tomography(PET), spatial resolution degradation occurs outside the field of view(FOV). To solve this problem, a depth of interaction(DOI) detector was developed that measures the position where gamma rays and the scintillator interact. There are a method in which a scintillation pixel array is composed of multiple layers, a method in which photosensors are arranged at both ends of a single layer, a method in which a scintillation pixel array is constituted in several layers and a photosensor is arranged in each layer. In this study, a new type of DOI detector was designed by analyzing the characteristics of the previously developed detectors. In the two-layer detector, different sizes of scintillation pixels were used for each layer, and the array size was configured differently. When configured in this form, the positions of the scintillation pixels for each layer are arranged to be shifted from each other, so that they are imaged at different positions in a flood image. DETECT2000 simulation was performed to confirm the possibility of measuring the depth of interaction of the designed detector. A flood image was reconstructed from a light signal acquired by a gamma-ray event generated at the center of each scintillation pixel. As a result, it was confirmed that all scintillation pixels for each layer were separated from the reconstructed flood image and imaged to measure the interaction depth. When this detector is applied to preclinical PET, it is considered that excellent images can be obtained by improving spatial resolution.

Stories have been studied as an important educational method in Christian education. In recent discussions on religious education, stories are positively evaluated in terms of stimulating children's unique fantasy, as opposed to visual media, and in terms of face-to-face direct communication. Our most profound and passionate orientation to the world is shaped by stories. This is because stories move us by moving us and shape our unconscious to act accordingly. However, the subjects that supply stories to children now are various mass media and consumer culture. The story it tells instills a secular worldview and makes us dream of a world completely different from the kingdom of God. Our children need a story to imagine the kingdom of God. This paper focuses on story-style sermons in children's worship and tries to deal with the Christian educational implications of story-style sermons. To this end, first of all, I would like to treat the Bible as a story according to the approximate concept of the story and the position of literary criticism who approached the Bible as a story. The second will deal with narrative preaching. First, we will look at narrative sermons for adults, and then deal with narrative sermons for children. The two narrative sermons were treated separately in the sense of considering the characteristics of children rather than being separated. Lastly, I would like to draw out the Christian educational implications of narrative preaching.

In radiotherapy, it may happen to radiate surrounding normal tissue because of inconsistent field size by changing patient position during treatment. We are going to analyze errors reduced by using immobilization device with Electonic portal imaging device(EPID) in this study. We had treated the twenty-one patients in pelvic region with 10 MV X-ray from Aug. 1998 to Aug. 1999 at Chungnam National University Hospital. All patients were treated at supine position during treatment. They were separated to two groups, 11 patients without device and 10 patients with immobilization device. We used styrofoam for immobilization device and measured the errors of anterior direction for x, y axis and lateral direction for z, y axis from simulation film to EPID image using matching technique. For no immobilization device group, the mean deviation values of x axis and y axis are 0.19 mm. 0.48 mm, respectively and the standard deviations of systematic deviation are 2.38 mm, 2.19 mm, respectively and of random deviation for x axis and y axis are 1.92 mm. 1.29 mm, respectively. The mean deviation values of z axis and y axis are -3.61 mm. 2.07 mm, respectively and the standard deviations of systematic deviation are 3.20 mm, 2.29 mm, respectively and of random deviation for z axis and y axis are 2.73 mm. 1.62 mm, respectively. For immobilization device group, the mean deviation values of x axis and y axis are 0.71 mm. -1.07 mm, respectively and the standard deviations of systematic deviation are 1.80 mm, 2.26 mm, respectively and of random deviation for x axis and y axis are 1.56 mm. 1.27 mm, respectively. The mean deviation values of z axis and y axis are -1.76 mm. 1.08 mm, respectively and the standard deviations of systematic deviation are 1.87 mm, 2.83 mm, respectively and of random deviation for x axis and y axis are 1.68 mm, 1.65 mm, respectively. Because of reducing random and systematic error using immobilization device, we had obtained good reproducibility of patient setup during treatment so that we recommend the use of immobilization device in pelvic region of radiation treatment.

In this study, radiographic evaluation was made using panoramic radiography and cross-sectional tomography of SCANORA/sup (R)/ in male and female adults in their 20's on the relationship between the maxillary sinus floor and the apex of the maxillary molar, to test the accuracy and effectiveness of the cross-sectional tomography, and to use this information in the assessment of preop. and postop. root canal treatment, apical surgery, extraction and implantology. Forty-one adults with an average age of 24.4 years were studied using panoramic radiography and cross-sectional tomography. In panoramic view and cross-sectional view, the position of the apices of maxillary molars were classified as separated, contacted, or protruded type; the general shape of the maxillary sinus floor was evaluated horizontally and vertically from cross-sectional tomography. The accuracy of each radiography was tested using maxilla from 5 fresh cadavers from the Anatomy Lab at Yonsei University Dental College, and panoramic view and cross-sectional tomography were taken in the same condition as with the patients. The results were as follows: 1. Panoramic view and cross-sectional view were taken in the maxilla specimen, and the actual distance between the maxillary sinus floor and the tooth apices were measured in the specimen; the median values of the distance from the tooth apices to the maxillary sinus floor in the panoramic view, cross-sectional view and in the actual maxilla specimen were 2.83 mm, 4.51mm, and 4.l5mm, respectively. In the cross-sectional view, the measured distance was close to the actual distance but in the panoramic view, the measured distance was far from the actual distance. 2. When the results of the panoramic view and cross-sectional view were compared, 40.5％ of the results agreed with each other in the two radiographic methods and buccal roots of the 2nd molar were the closest to the maxillary sinus floor in the cross-sectional tomography. 3. In cross-sectional view, when the vertical relationship of the maxillary sinus floor and maxillary roots was assessed, in 1st molars, type II (the sinus floor that extends down to the buccolingual furcation area) was predominant, while in 2nd molars, type I (the sinus floor located above the level connecting the buccal and lingual apices) was predominant. In the horizontal relationship, in 1st molars, type II (the lowest floor of the maxillary sinus located in between the buccal and lingual roots) was predominant; in 2nd molars, type I (the lowest floor of the maxillary sinus located on the buccal side of the buccal roots) and type II appeared in similar frequency. In conclusion, the SCANORA/sup (R)/ cross-sectional tomography was more effective than the frequently used panoramic view, in that the relationship of the maxillary molars and maxillary sinus floor can be evaluated more accurately and the buccolingual cross-sectional view can also be observed. And maxillary sinus floor that was close to maxillary 2nd molar had tendency to be located on buccal side than that close to 1st molar. Therefore, cross-sectional tomography is an effective and accurate method to evaluate the position of the teeth in relation to the sinus floor preoperative and can be easily used to diagnose localized periapical lesions. Also, the image quality obtained was quite satisfactory.

This study conducted a research on the position, construction of space and plants of Ten Evergreen's Garden(十靑園) and Oddly Shaped Stone Garden(怪石園) that are central gardens of Eunguhdang(恩居堂) in the poem 'Statement of Responsibility'(Heo Mok, 1595~1682) and Sochi(小痴) Heo Ryeon(許鍊)'s 'Taeyeongsipcheongwondo(漣川台嶺十靑園圖)' in order to bring light on the construction of space and characteristics of them as a garden of the deep pond, Eunguhdang that is a historic site of Misu Heo Mok(許穆, 1595~1682). The characteristics of Eunguhdang, and the meaning of it from the research are expected to be utilized as a basic data for future restoration of it. The results are as follow: In Eunghudang, there are the main building, a detached house, a separated building, and servants' quarters, and the garden consists of Ten Evergreen's Garden between the main building and a Byeolmyo(別廟), a backyard which leads to a green mountaintop, and Oddly Shaped Stone Garden including a pavilion in the front of the detached house. These gardens are thought to have utilized various oddly stones. From the analysis of existing documents such as 'Gwuimonwon(龜文園)' and several interviews, it is concluded that Gwuimunwon might have had Youngdoseo(龍圖墅) that imitated a stream, and Oddly Shaped Stone Garden might have had a garden which imitates Guimonwon standing for graffiti. The evergreen plants in Gwuimonwon correspond to the plants of Sipjangcheong(十長靑) in Youngdoseo, and through these facts, it is thought to have sought "The clean and cool". Furthermore, the diverse colors of flowering trees and flowers in Oddly Shaped Stone Garden and the surrounding of it is symbolizing dragon which is found in Gwuimonwon and that is contrasting with the evergreen plants in Gwuimonwon. The oddly shaped stones in the garden of Eunguhdang have a strange atmosphere which is felt across the whole buildings in Misu, and s a same aesthetic object that are thought to have created beauty of old greenery and antique appearance by utilizing oddly shaped stones. Misu is based on ever green plants seeking change with flowers along with stones that means spirit, body and bones, which is strengthening his intention.

Several isotopomers of cyclooctanone were prepared by selective deuterium substitution. Intrinsic isotope effects on $^{13}C$ NMR chemical shifts of these isotopomers were investigated systematically at low temperature. These istope effects were discussed in relation to the preferred boat-chair conformation of cyclooctanone. Deuterium isotope effects on NMR chemical shifts have been known for a long time. Especially in a conformationally mobile molecule, isotope perturbation could affect NMR signals through a combination of isotope effects on equilibria and intrinsic effects. The distinction between intrinsic and nonintrinsic effects is quite difficult at ambient temperature due to involvement of both equilibrium and intrinsic isotope effects. However if equilibria between possible conformers of cyclooctanone are slowed down enough on the NMR time scale by lowering temperature, it should be possible to measure intrinsic isotope shifts from the separated signals at low temperature. $^{13}C$ NMR has been successfully utilized in the study on molecular conformation in solution when one deals with stable conformers or molecules were rapid interconversion occurs at ambient temperature. The study of dynamic processes in general requires analysis of spectra at several temperature. Anet et al. did $^1H$ NMR study of cyclooctanone at low temperature to freeze out a stable conformation, but were not able initially to deduce which conformation was stable because of the complexity of alkyl region in the $^1H$ NMR spectrum. They also reported the $^1H$ and $^{13}C$ NMR spectra of the $C_9-C_{16}$ cycloalkanones with changing temperature from $-80^{\circ}C$ to $-170^{\circ}C$, but they did not report a variable temperature $^{13}C$ NMR study of cyclooctanone. For the analysis of the intrinsic isotope effect with relation to cylooctanone conformation, $^{13}C$ NMR spectra are obtained in the present work at low temperatures (up to $-150^{\circ}C$) in order to find the chemical shifts at the temperature at which the dynamic process can be "frozen-out" on the NMR time scale and cyclooctanone can be observed as a stable conformation. Both the ring inversion and pseudorotational processes must be "frozen-out" in order to see separate resonances for all eight carbons in cyclooctanone. In contrast to $^1H$ spectra, slowing down just the ring inversion process has no apparent effects on the $^{13}C$ spectra because exchange of environments within the pairs of methylene carbons can still occur by the pseudorotational process. Several isotopomers of cyclooctanone were prepared by selective deuterium substitution (fig. 1) : complete deuterium labeling at C-2 and C-8 positions gave cyclooctanone-2, 2, 8, $8-D_4$ : complete labeling at C-2 and C-7 positions afforded the 2, 2, 7, $7-D_4$ isotopomer : di-deuteration at C-3 gave the 3, $3-D_2$ isotopomer : mono-deuteration provided cyclooctanone-2-D, 4-D and 5-D isotopomers : and partial deuteration on the C-2 and C-8 position, with a chiral and difunctional case catalyst, gave the trans-2, $8-D_2$ isotopomer. These isotopomer were investigated systematically in relation with cyclooctanone conformation and intrinsic isotope effects on $^{13}C$ NMR chemical shifts at low temperature. The determination of the intrinsic effects could help in the analysis of the more complex effects at higher temperature. For quantitative analysis of intrinsic isotope effects, the $^{13}C$ NMR spectrum has been obtained for a mixture of the labeled and unlabeled compounds because the signal separations are very small.

The aim of this study was provide basic information and establish the criteria in radiation therapy planning by measuring the absorbed neutron dose of normal tissues and lesions according to the number of portals. From September 2013 to January 2014, 20 patients who were diagnosed with prostate cancer and were previously treated with radiation therapy were replanned retrospectively to measure the absorbed neutron dose distribution according to the number of portals. The absorbed neutron dose was measured in each of the 5, 7 and 9 portals using a 15 MV energy, which meant a therapeutic dose of 220 cGy. The optical stimulation luminescence dosimeter was separated by 20cm and 60cm away from the center of the field of view. As a result, the average radiation dose in the abdomen appeared to have a positive relationship with the number of portals, which was statistically significant (p<.05). The average radiation dose was $4.34{\pm}1.08$. The average radiation dose in the thyroid was $2.71{\pm}.37$. Although it showed a positive relationship with the number of portals, it did not have statistical significance. The number of portals and the neutron dose depending on the position showed a significant positive relationship, particularly in the abdomen. As a result of linear regression analysis, as the number of the portal increased in steps, the average volume of the neutrons increased significantly (0.416 times). In conclusion, efficient selection of the number of portals is needed considering the difference in the absorbed neutron dose in the normal tissues depending on the number of the portals.

Accounting for tumor motion in treatment planning and delivery is one of the most recent and significant challenges facing radiotherapy. The purpose of this study was to investigate the correlation and clarified the relationship between the motion of an external marker using the Real-Time Position Management (RPM) System and an internal organ motion signal obtained fluoroscope. We enrolled 10 patients with locally advanced lung cancer and liver cancer, retrospectively. The external marker was a plastic box, which is part of the RPM used to track the patient's respiration. We investigated the quantitatively correlation between the motions of an external marker with RPM and internal motion with fluoroscope. The internal fiducial motion is predominant in the caraniocaudal direction, with a range of $1.3{\sim}3.5cm$ with fluoroscopic unit. The external fiducial motion is predominant in the caraniocaudal direction, with a range of $0.43{\sim}2.19cm$ with RPM gating. The two measurements ratio is from 1.31 to 5.56. When the regularization guided standard deviation is from 0.08 to 0.87, mean 0.204 cm, except only for patients #3 separated by a mean 0.13 cm, maximum of 0.23 cm. This result is a good correlation between internal tumor motion imaged by fluoroscopic unit and external marker motion with RPM during expiration within 0.23 cm. We have demonstrated that gating may be best performed but special attention should be paid to gating for patients whose fiducials do not move in synchrony, because targeting on the correct phase difference alone would not guarantee that the entire tumor volume is within the treatment field.
