Archival description in archives has an important role in document control and reference service. Archives has made an effort to do archival description. But we have some differences and problems about a theory and practical processes comparing with advanced countries. The serious difference in a theory is that a function classification, maintenance of an original order, arrangement of multi-level description are not reflected in practical process. they are arranged in shelves after they are arranged by registration order in a unit of a volume like an arrangement of book. In addition, there are problems in history of agency change or control of index. So these can cause inconvenience for users. For improving, in this study we introduced the meaning and importance of arrangement of description, the situation and problem of arrangement of description in The National Archives, and a description guideline in other foreign countries. The next is an example for ISAD(G). This paper has chapter 8, the chapter 1 is introduction, the chapter 2 is the meaning and importance of arrangement of description, excluding the chapter 8 is conclusion we can say like this from the chapter 3 to the chapter 7. In the chapter 3, we explain GOVT we are using now and description element category in situation and problem of arrangement of description in Archives. In the chapter 4, this is about guideline from Archives in U.S.A, England and Australia. 1. Lifecycle Date Requirement Guide from NARA is introduced and of the description field, the way of the description about just one title element is introduced. 2. This is about the guideline of the description from Public Record Office. That name is National Archives Cataloguing Guidelines Introduction. We are saying "PROCAT" from this guideline and the seven procedure of description. 3. This is about Commomon Record Series from National Archives of Australia. we studied Registration & description procedures for CRS system. In the chapter 5, This is about the example which applied ISAD to. Archives introduce description of documents produced from Appeals Commission in the Ministry of Government Administration. In the chapter 6, 7. These are about the problems we pointed after using ISAD, naming for the document at procedure section in every institution, the lack of description fields category, the sort or classification of the kind or form, the reference or identified number, the absence description rule about the details, function classification, multi-level description, input format, arrangement of book shelf, authority control. The plan for improving are that problems. The best way for arrangement and description in Archives is to examine the standard, guideline, manual from archives in the advanced countries. So we suggested we need many research and study about this in the academic field.

This study conducted experiment for understanding engineering characteristics of domestic sands by examining standard sand and sand from Yokji Island and Nakdong River in terms of confining pressure, $K_0$, over consolidation and relative density factors through triaxial compression test. The test showed that deviator stress by strain positively changed as confining pressure and relative density grow while $K_0$ and over consolidation factors do not directly correlated with it. Angle of internal friction decreases as confining pressure increases which strengthens contact force between particles, and declines as relative density drops, whereas $K_0$ and over consolidation factors hardly affect the results. When it comes to volumetric strain, volume expansion decreases as confining pressure increase due to crushability and rearrangement of particles while $K_0$ and over consolidation shows same movement unconditionally, and relative density appears compressed as it grows at the beginning however it expands as axial strain increases. Modulus of elasticity ($E_{sec}$) by strain has tendency into convergence resulting in initial secant modulus of elasticity ($E_{ini}$) > secant modulus of elasticity($E_{sec}$) > tangent modulus of elasticity ($E_{tan}$). On the other hand, it grows as confining pressure and relative density increase while indicating similar modulus of elasticity ($E_{sec}$) regarding on $K_0$ and over consolidation. Slope of critical line (M) tended to decrease as confining pressure increases, follow same line according to $K_0$, confining pressure and relative density, and increase as relative density grows.

As a basic research material to make more efficient healthcare and health promotion for dental hygienists, this study intends to determine which factors may affect their awareness of occupational diseases. For this sake, this study attempted to investigate into a variety of literatures and data, and applied a questionnaire survey to 160 dental hygienists for about 5 months(from June to October 2003), who were all employed in domestic dental clinics or offices. As a result of analysis, this study can be concluded as follows: (1) The result of analyzing how dental hygienists recognized their occupational diseases showed that 'stiffness in muscle, neck or shoulder due to intensive use of specific physical regions' and 'stress resulting from the attributes of each task' reached the highest awareness(90.6%) of all, which was followed by 'lower eyesight due to detailed or even sophisticated tasks for many hours(65%)' and 'symptoms of ruptured disk due to standing tasks as dental hygienists do for many hours(62.5%).' (2) The result of analyzing how dental hygienists recognize their occupational diseases showed that their awareness averaged 7.28 points out of 14 points, which implies that their awareness of occupational diseases is not very high. Meanwhile, the result of examining how they recognize detrimental or harmful properties of given materials against human body showed that a majority of total respondents(74.4%) regarded given materials as detrimental to human body. (3) The result of examining how dental hygienists recognize their occupational diseases showed that a majority of total respondents(91.9%) identified their own occupational diseases. Many of total respondents(41.9%) pointed out that environmental improvement around workshop in each clinic or office should be foremost prerequisite to health and welfare for dental hygienists. Next, 34.4% of total respondents pointed out the necessity to perform in-house health diagnosis and examination on a regular basis, and 13.1% of total respondents thought it necessary to carry on healthcare education into harmful properties in the aspect of dental materiology, respectively.

The experiment was carried out to investigate the chemical properties of cement kiln dusts, abundantly produced from cement industry as a byproduct, and their effectiveness on rice yield. The field experiment was conducted on the acid paddy soil developed on basalt at Dongsong-Myon, Chulwon-Kun, Gangwon-Do. Two kinds of cement kiln dusts were used ; By Pass (BP) collected from the suspension preheater and Electric Precipitate (EP) from the cottrell electric precipitator. The levels of cement kiln dust applied were 100kg/10a, 200kg/10a and 300kg/10a, and the recommended variety "Nong Back" was adopted for this experiment. The results obtained are summarized as follows ; 1. The component of cement kiln dusts seems to be quite suitable for liming material. BP has 55% alkalinity, 41.7% of soluble calcium, 9.8% of soluble magnesium and 4.5% of water soluble silicate, while EP has 53.5% alkalinity, 41.7% soluble calcium, 8.3% soluble magnesium and 1% water soluble silicate. 2. The relative effectiveness of cement kiln dust in the soil will be superior due to very fine particle size. EP pass through completely 270 mesh screen, and 95% of BP pass through 150 mesh screen, 68% passing 270 mesh. 3. BP application at the rate of 100kg/10a increased 21% of rice yield as compared with control and EP 15%. It was observed that the affected yield components were increased panicle number per hill, grain number per panicle and 1,000 grains weight. 4. The application of optimum amount (100kg/10a) of cement kiln dusts accelerated the uptake of nutrients by rice plant and increased rice yield. However, the excess amounts (200kg/10a, 300kg/10a) of cement kiln dusts retarded the uptake of nutrients from soil.

For the purpose of utilization in 3-D conformal radiotherapy and whole body radiosurgery, the Whole Body 3-Dimensional Topographic Radiation Therapy System has been developed. Whole body frame was constructed in order to be installed on the couch. Radiopaque catheters were engraved on it for the dedicated coordinate system and a MeV-Green immobilizer was used for the patient setup by the help of side panels and plastic rods. By designing and constructing the whole body frame in this way, geometrical limitation to the gantry rotation in 3-D conformal radiotherapy could be minimized and problem which radiation transmission may be altered in particular incident angles was solved. By analyzing CT images containing information of patient setup with respect to the whole body frame, localization and coordination of the target is performed so that patient setup error may be eliminated between simulation and treatment. For the verification of setup, the change of patient positioning is detected and adjusted in order to minimize the setup error by means of comparison of the body outlines using 3 CCTV cameras. To enhance efficiency of treatment procedure, this work can be done in real time by watching the change of patient setup through the monitor. The method of image subtraction in IDL (Interactive Data Language) was used to visualize the change of patient setup. Rotating X-ray system was constructed for detecting target movement due to internal organ motion. Landmark screws were implanted either on the bones around target or inside target, and variation of target location with respect to markers may be visualized in order to minimize internal setup error through the anterior and the lateral image information taken from rotating X-ray system. For CT simulation, simulation software was developed using IDL on GUI(Graphic User Interface) basis for PC and includes functions of graphic handling, editing and data acquisition of images of internal organs as well as target for the preparation of treatment planning.

The purpose of this paper is to examine the concept of "accident" under the Warsaw system including the Warsaw Convention for the Unification of certain Rules for International Carriage by Air of 1929 and the Montreal Convention of 1999. Most leading case on this subject is Air France v. Saks(470 U.S. 392 (1985)). In the Saks case, it was held that the definition of an accident must be applied flexibly, and most courts have adhered to the definition of accident in Saks case, the application of accident has been less than consistent. However, most cases have held that if the event is usual and expected operation of the aircraft, then no accident has occurred. Courts have also held that where the injury results from passenger's own internal reaction to the usual, normal, and expected operations of the aircraft, it is not caused by an accident. As the Warsaw drafters intended to create a system of liability rules that would cover all hazards of air travel, the carrier should liable for the inherent risks of air travel. It is right in that the carrier is in a better position than the passenger to control the risks during air travel. Most US courts have held that carriers are not liable for one passenger's assault on the other passenger. The interactions between passengers are not part of the normal operations of the aircraft and are therefore not covered by the word "accident" under Art 17 of the Warsaw Convention. It is regretful that the Montreal Convention did not attempt to clarify the concepts of accident in itself. In the light of an emerging tendency to hold the air carrier liable for occurrences that do not exactly go to the operation of the aircraft, it is desirable to regulate that the carrier is liable for an "event" instead of an "accident" in accordance with the Guatemala City protocol.

Traditional medicinal plants are widely used to treat many diseases, such as inflammation, infections, and even cancer. Ulmus macrocarpa Hance, a Chinese elm species, is distributed in Korea, China, and Japan. The stem bark is widely employed in Korean traditional medicine to treat dermatitis, mastitis, and edema. The aim of this study was to investigate whether water extract of U. macrocarpa Hance bark (Ulmus cortex) has a immune-modulating function in a mouse model. Three different concentrations (30 mg/kg, 100 mg/kg, and 300 mg/kg) of Ulmus cortex water extract (UCWE) were orally administered to mice for 14 days, and their immune responses were analyzed. Cytokines, such as interleukin (IL)-2, IL-12, and IFN-${\gamma}$, increased in the blood of UCWE-fed groups when compared with a control group. In contrast, the IL-4 level did not change in any of the UCWE-fed groups Cell-mediated cytotoxicity was also assayed using lymphokine-activated killer cells (LAK). LAK showed greater cytotoxicity in the UCWE-fed groups than LAK in the control group. Internal organ indices, such as liver, kidney, spleen, and thymus, were similar in all the groups, including the control group, indicating that UCWE may have been nontoxic in the experimental animals. These data suggest that UCWE has an immune-modulating function in a mouse model.

Endotracheal suctioning is a routine procedure used for clearing secretions from the airway of the intubated infant. This procedure is not without complications. Endotracheal suctioning has been associated with decreases in $PaO_2$, decreases in systemic venous oxygenation, alterations in mean arterial Pressure, disturbances in cardiac rhythm and development of nosocomial pneumonia. So several endotracheal suctioning techniques have been developed to prevent these blown complications. Another method of Endotracheal suctioning eliminates the risk associated with disconnecting the infant from the ventilatior to perform the suctioning procedure. Studies examining closed endotracheal suctioning methods reported that the closed method results in less arterial oxygen saturation, and less systemic venous oxygen desaturation. However those studies have focused on adult patients, and there have been no published studies for newborn infants. The specific purpose of this study is to investigate the two methods and to make a comparison in terms of (1)variations in $SaO_2$, heart rate, and respiration rate appeared before and after the endotracheal suctioning; (2)difference in occurrence of nosocomial infection; (3)difference in recovery time to arrive at pre-suction baseline after suctioning and in nursing time taken for the suctioning. The present study is based on the data obtained from two groups of newborn infants : one group comprises 8 infants with closed suctioning (a total of 304 suctions) among 17 infants treated with ventilator and the other group 9 infants with open method (a total of 629 suctions). The data were analyzed using the SPSS statistical program package. As the distribution test on dependent variables with the Skewnesser Shapiro Wilk test showed an asymmetric distribution, the Wilcoxon Matched-pairs Singled- Ranks test was used for the test of variations in $SaO_2$, heart rate, and respiration rate appeared before and after the endotracheal suctioning. The difference in $SaO_2$ recovery time and nursing time was analyzed with the Mann-Whitney U-Test. The difference in physiologic consequences and occurrence of nosocomial infection between the two groups was analyzed with the Fisher's Exact Test. The results of the study are summarized as follows. For the hypothesis 1 (There would be a difference in $SaO_2$, heart rate, and respiration rate before and after suctioning between the two suctioning methods), the difference in $SaO_2$ turns out to be statistically significant (P=0.015), but heart rate and respiration rate do not procedure a notable difference (P=0.630). The hypothesis 2 (There would be a difference in rates at which a complication arises after suctioning between the two groups) does not prove to be statistically valid (P=0.246). For the hypothesis 3(There would be a difference in $SaO_2$ recovery time and nursing time between the two groups), the average $SaO_2$ recovery time after suctioning turned out to have somewhat significant difference (P=0.064), however the difference in nursing time taken for the suctioning was not statistically significant (P=0.610). The analyses indicate that the closed endotracheal suctioning is more efficient as compared with the open method, in maintaining pre-suction baseline $SaO_2$ and a rapid recovery of newborn infants. Based on these results we suggust to apply the closed method to newborn infants in the ventilation treatment. We also suggest to extend the investigation to include the comparison of suction cost taking into account the case in which a complication arises after endotracheal suctioning between the two groups.
