This dissertation is considerably studied Faction Genre which is embossed as a new image content, and it is figured out practical used works' possibilities for Korea film production's varieties. Faction, a neologism, which is combined by Fiction and Fact, is a boundary as limits. If authentic history is closed to a truth, it is a record history description method. Also, if unauthorized history is closed to a fake, it is a fictitious history description method. In addition, macro history and micro history are respectively connected to social criticism's matter and personal action, and these can make various analyses, depend on a boundary's limits and personal analysis. On the other hand, history film could be remembered to audience merely history film itself without existed history's fact. However, there are Faction Genre's Genre possibility and film's attraction which indirectness experience of historic fact could be experienced through film. For Faction Genre’s developing solution, there are three cognitive switches; audience's interpretation ability about history film through watching perception, linking between the past and the present for audience through communication with history, audience's considerable decision about history first or fiction first as film writer's interpretation. Above all, hopefully filmic pressure can be shown with historical true to audience. Therefore, it would be Korea Faction Genre's attraction and hope.

The "tang[tɑ:ŋ]" in Korean pronounciation means the beverage made of boiled medicinal herbs. The"Jeho-tang", the name of Drink in this abstract, is described in a variety of medical books including the "Dongeui Bogam" as being effective for illness from the summer heat in promoting digestion, curing the heatstroke and bringing it to a halt. The Drink was used as the Royal gifts granted to retainers and royal families on the Day of Dano-festival on the fifth of the fifth month of the year according to the lunar calendar, the items of encouragement for those who worked hard in sacrifices, and the awards for students of Confucianism who were proficient in their learning. The Jeho-tang used in this study was scientifically cooked again after a long time in history through looking at the methods written in the documents concerned with the Drink such as the "Dongeui Bogam" and the "Taste of Korea". In preparation of the medicinal herbs for the Drink, the powder of thinner than 30 mesh of the "Prunus mume", which is a species of Asian plum in the family of Rosaceae, and those of 50 mesh of the "Santalum album", which is the fragrant wood of trees in the genus Santalum and the "Amomum Xanthioides", which is produced in Vietnam and is the name of a kind of herb medicines, being very effective in the desease caused from heatstrare, were used. The sugar concentration of the honey boiled down long time at low heat was $82.43^{\circ}Bx$. When cooking in a double boiler, the inner part of the liquid for the Drink was kept at $80^{\circ}C$ for 12 hours to make it finished in a state of ointment. In the general composition of the finished Jeho-tang, the moisture content was 24.4%, 1.3% of crude fat, 1.4% crude protein and 0.7% ash, along with pH3.2. The acceptance on the whole was come out to be the highest in the sample diluted with the drinking water of 7-fold of the Jeho-tang, indicating that the 7-fold's addition of water was optimum level for drinking. In the Drink cooked by a vaccum pressure extractor for herb medicine, which was developed to improve the art of cooking, the longer the time of pressure was, the less the heterogeneous feeling at tongue was and the more the glossiness of the Drink was. The Jeho-tang cooked under pressure for 7 hours received an excellent evaluation in its acceptability in every way.

In an attempt to examine the risk factors and analyze an odds ratio for risk factors associated with mild and moderate. severe hypertension, this study was carried out from August, 1987 to September, 1997. From periodic health examinations of insured adults, 747 subjects were assigned to nomotensives, mild hypertensives and moderate' severe hypertensives. Major findings obtained from the study are as follows: 1. The Body mass index(BMI) was revealed a significant difference among the 3 groups. Also, there was a significant positive correlation between the BMI and systolic, dyastolic blood pressure. 2. Cholesterol was revealed to be significantly different among the 3 groups. Also, there was a significant positive correlation between the cholesterol and systolic, dyastolic blood pressure. 3. Urine protein and a cardiovascular family history was revealed to be significantly different among the 3 groups. The presence of urine protein and cardiovascular family history were significantly higher in hypertensives than nomotensives. 4. A preference for salty food, a preference for flesh and the frequency of flesh eating were not significantly different among the 3 groups. 5. Smoking habits, frequency and duration of cigarette smoking were not significantly different among 3 groups. 6. The habit of alcohol consumption and the frequency and duration of alcohol consumption were not significantly different among the 3 groups. 7. The habit of exercise and its frequency and duration were not significantly different among the 3 groups. 8. Statistically significant elevated odds ratios were noted in the following BMI(mild hypertensives; 2.48, moderate. severe hypertensives ; 4.65), urine protein(mild hypertensives ; 2.37, moderate. severe hypertensives; 6.77), cholesterol(moderate. severe hypertensives ;1.64), cardiovascular family histoy(moderate severe hypertensives; 4.77). Based on these results, the significant risk factors of mild, moderate. severe hypertension were BMI, cholesterol, urine protein, and family history, but diet, smoking, alcohol consumption, and exercise had no significant association.

The aim of this study is to investigate the characteristics on the profile of local ice load acting on side shell of port side in bow part due to broken ice during icebreaking of ships in ice covered waters. The first Korean icebreaking research vessel 'ARAON' had a sea ice field trial in the Arctic Sea during early August, 2010, and the signals due to local ice impact measured from several strain gauges installed at bow part were gathered. It is known that these data with structural response characteristics due to local ice impact have some different characteristics with a typical hydraulic impact pressure - time history. In this study, the time history on the measured signals was analyzed and the characteristic values were presented using non-dimensional parameters.

This study suggests a method predicting at-rest coefficient of earth pressure ($K_0$) in order to evaluate the effect of stress history of granular soil. The method is based on the relation $K_D/K_0={\chi}(E_D/{\sigma}_m{^{\prime}})^{\delta}$, which is developed by combining two previously published relations such as $E_D/{\sigma}_m{^{\prime}}-{\psi}$ and $K_D/K_0-{\psi}$. As $K_D$ and $E_D$ are observed to be sensitive to the pre-stress, both indices are adopted for the estimation of $K_0$ value of granular soil. It is shown that the proposed $K_D/K_0-E_D/{\sigma}_m{^{\prime}}$ relation is insignificantly affected by the stress history. It is concluded from the comparative study that the proposed method, which uses only dilatometer test results to predict the $K_0$ of granular soil, provides more convenient and reliable prediction than other methods which use both CPT and DMT results.

The use of the epoxy pressure injection technique to rehabilitate reinforced concrete beam-column joints damaged by strong earthquakes is investigated experimentally and analytically. Two one-half-scale exterior beam-column joint specimens were exposed to reverse cyclic loading similar to that generated from strong earthquake ground motion, resulting in damage. Both specimens were typical of new structures and incorporated full seismic details in current building codes. Thus the first specimen was designed according to Eurocode 2 and Eurocode 8 and the second specimen was designed according to ACI-318 (1995) and ACI-ASCE Committee 352 (1985). The specimens were then repaired with an epoxy pressure injection technique. The repaired specimens were subjected to the same displacement history as that imposed on the original specimens. The results indicate that the epoxy pressure injection technique was effective in restoring the strength, stiffness and energy dissipation capacity of specimens representing a modem design.

A simplified statistical methodology is developed in order to both reduce over-conservatism of deterministic methodologies employed for PWR fuel rod internal pressure (RIP) calculation and simplify the complicated calculation procedure of the widely used statistical methodology which employs the response surface method and Monte Carlo simulation. The simplified statistical methodology employs the system moment method with a deterministic approach in determining the maximum variance of RIP The maximum RIP variance is determined with the square sum of each maximum value of a mean RIP value times a RIP sensitivity factor for all input variables considered. This approach makes this simplified statistical methodology much more efficient in the routine reload core design analysis since it eliminates the numerous calculations required for the power history-dependent RIP variance determination. This simplified statistical methodology is shown to be more conservative in generating RIP distribution than the widely used statistical methodology. Comparison of the significances of each input variable to RIP indicates that fission gas release model is the most significant input variable.

This study aims to provide a fundamental data for directly injected hydrogen fuel engines. Spray, ignition and combustion characteristics of hydrogen were studied using constant volume chamber. For spray visualization, hydrogen was vertically injected into a combustion chamber at various condition, for example, injection pressure, ambient pressure. And an argon laser was used for the shadowgraph photography by applying optical method. Also, to investigate heat-release rate and flame propagations, spark was ignited on hydrogen injected at the different time after injection and the duration of injection was also changed. Processes of ignition and combustion were analyzed by heat-release rate calculated by pressure history and were observed by shadowgraph photography The results gave much knowledge of spray, ignition and combustion characteristics of hydrogen.

Accurate description of starting transient history allows and justifies the use of small margin of safety for the engine parts, resulting in high motor mass ratio in addition to satisfying the control and guidance requirements of the vehicle. Studies have been carried out for the prediction and reduction of ignition peak and pressure-rise rate during the starting transient of solid rocket motors. Numerical studies have been carried out using a two dimensional Navier-Stokes solver. It has been inferred through the parametric studies that, in the case of solid rocket motors with uniform port, high ignition peak is observed at high spread rate and low pressure-rise rate. In the case of the port with sudden expansion configuration, high ignition peak is observed at relatively high average spread rate and high-pressure rise rate. These studies are expected to aid the designer in reducing the ignition peak by altering the propellant properties or igniter characteristics without sacrificing the motor performance.

The wind load on building surface is numerically investigated. The geometry of target building is a square cross section and aspect ratio (height (H) to width (d)) is 6. On building surface, the pressure was measured, compared to obtained value from numerical simulation. The numerical simulations were done using URANS with three different turbulence models such as v2-f model, k-${\omega}$model, and k-${\varepsilon}$ model, respectively. The v2-f model showed the best agreement with experimental data in simulating mean pressure coefficients on front, rear and side surface. But unsteady characteristics of pressure history measured on surface is shown a discrepancy between experiment and numerical simulation.
