The purpose of this study is to verify the change of the water surface elevation and velocity after and before development in Gwangyang bay reclaimed at about 23%. The numerical analysis was executed using a RMA-2 model of the finite element method. As a result, it turned out that the flow velocity around the Myodo sea area in Gwangyang bay decreased. As comparing the north channel of Myodo island to the south channel of Myodo island, the south channel of Myodo island was showing more than 10% of decrease in flow velocity. The change of water surface elevation was calculated at 5 points in Gwangyang bay. At the high waters of spring tides, it was founded that generally the water surface elevation after reclamation increased relative to before reclamation in Gwangyang bay and as going to the west in Gwangyang bay, the amount of increase was getting larger.

A Damages of the public structures by localized torrential downpour burdened the Nationality with high cost and cause social life inconvenience. To reduce these damages. It is very useful that the cause of the failures are clear by the collection and analyse of the past failure data. It is inferenced that the failure cause of small dam is missing the sluice opening time and the failure cause of bridges is the insufficiency of the resisting force to drag force. Therefore. It is necessary for small dam keep in touch with the water resources management of the multipurpose dam and for bridge is reinforced with the design of the bridge piers and abutment to resist with scour and drag force.

Hydrau1ic experiments were carried out to investigate the hydraulic charactcristics of the breakwater with two types of under conduit for regular waves of various heights and periods. 1t was found that the small value of steepness(HfL; ratio of wave height(H) to wave length(L)) and relative depth(djL; ratio of water depth(d) to wave length(L)) and the large value of period(T) have big transmission coefficient at breakwater with two types of under conduits. The larger wave steepness and relative depth, the smaller wave transmission rate. There was little difference of transmission at breakwater with small perforated rate.

Tidal propagation in the Sumjin River was perfomed via one-dimensional numerical model. The model was used to compute tidal distribution of the Sumjin River for low water flow, flood flow and to investigate the water level response within tidal regime by combined tides and flood discharges effects. Some of results are presented and discussed.

The global demand for air planes is rapidly increasing, with over 28,000 pilots expected to increase every year for the next 20 years. However, the supply of pilots is limited as it takes a long time to train one pilot and the budget requirement for pilot education is high. This has resulted in many nations around the globe competing to maintain an adequate number of pilots. Especially, the demand for pilots is mostly focused in Asia. The competition to recruit pilots is extremely high in China and low-cost airlines. As a result, the salaries of pilots are higher than ever. The Korean Air Force spends a lot of budget every year to train Air Force pilots, and the Air Force is also developing plans to prevent Air Force pilots from moving over to private airlines for higher salaries and better welfare. This study is a study on the effects of the pan-government Air Force pilot support policy that is designed to prevent expert level pilots from retiring from the Air Force. Expert level pilots are one of the key manpower resources of the Korean Air Force. In other words, this study has verified the effects of the Air Force pilot support policy on the job satisfaction, family-life satisfaction, and the organizational commitment of Korean Air Force pilots. After analyzing the results from a survey conducted against 378 Korean Air Force pilots, the Air Force pilot support policy showed to have a positive effect on the job satisfaction and family life satisfaction of Air Force pilots. Job satisfaction showed to have a positive effect on the family life satisfaction and organizational commitment of Air Force pilots. Family life satisfaction showed to have a positive effect on the organizational commitment of Air Force pilots. The implicit meanings of the verification results and what they suggest regarding government policies are also discussed.

It becomes base data for topographic and hydrologic analysis that evaluate surface change of basin, Various research using remote sensing recently is progressing, and it becomes indicator that analyze surface cange that evaluate land cover of surface using multi-spectral band. Maximum Likelihood Method is used with Landsat TM image in order to analyze surface change by yongdam dam construction in this study. There was no bi change in forest, dry field, build p area as analysis result. But, paddy area decreased from 15.07% in 1994 year to 10.73% in 2001 year that based on current water level. and, water area increased from 0.30% in 994 year to 4.01% in 2001 year that based on full water level. Also, gumgang 3 subbasin that is lowest basin showed highest water area by 23.95% of whole land cover.

From Jan. 1988 to July 1990, 1641 burn patients were admitted to Hangang Sacred Heart Hospital. Among them, 538 patients were under the age of fifteen. In these pediatric burn patients, retrospective study was done for the review of following issuses ; age and sex destribution, causes of burn, monthly, daily and hourly distribution of accidents, prevalent area of burn and duration of admission, mortality rate and causes of deaths according to the extents of burn. The results were as follows ; 1) Children under 15years old were 32.8% of all admitted burn patients(1641). 2) Males were more frequently affected, and their percentage was 56.9%. 3) The most prevalent age group was between 1 and 2 years old(27.1%). 4) The most common cause of burns were scalds(78.4%), followed by flame(19%), contact(1.7%) and electric(1%). 5) Burning accidents were frequently occurred in March and October, on Sunday and at 7-8PM, 1-2PM and 9-10AM. 6) Lower extremity was most frequently involved(36%), followed by upper extremity(22.6%), trunk(21.7%), hand(9.7%) and head & neck(9.6%). 7) The mean hospital day was 21.4% days, and days of admission were abruptly prolonged over 40% burn of total body surface. 8) Overall mortality rate was 8.1%(40 cases), and causes of deaths were sepsis(62.5%), respiratory failure(25%), asphyxia(2.5%), hypovolemic shock(2.5%) and CO intoxication(2.5%).

Eyebrow reconstruction is one of the procedures which is essential for the improvement of facial esthetics. For the reconstruction of eyebrow, composite strip graft, micrograft and superficial temporal artery island flap are frequently used. Among them, proper procedure should be selected with the consideration of size and shape of normal eyebrow, defect size, sex and vascularity of recipient site. We used superficial temporal artery island flaps in three male patients. For the first patient, one stage bilateral and subtotal reconstruction was performed with two separated scalp flaps which were based on right superficial temporal vessels. For the second patient, long axis of scalp flap was designed vertically on right side and horizontally on left side according to the direction of the scalp hair. For the third patient, right eyebrow was reconstructed with strip scalp graft because of traumatic loss of right superficial temporal artery and the result was not so good as left side, which was reconstructed with left superficial temporal artery island flap.
