Objectives: Cancer is the most frequent cause of death in Korea. Cancer screenings can save lives through early detection and their effect can be enhanced by regular repeat adherence rather than one-time screening. The aim of this study was to investigate major cancer screening rates and the reasons for not having screening for providing the basic data required. Materials and Methods: The study sample were recruited from the parents of students in 3 different middle and high schools in Pusan. 428 participants(l93 of males, 214 of females) completed a structured self-administered questionnaire from Dec. 21 to 31, 2001 and the response rate was 73.8%. Data were analyzed using descriptive statistics with SPSS Win 10.0. Results: The cancer screening rates of the subjects(male and female respectively) who have had one or more in their life-time were about 36.3% and 34.6% in gastroendoscopy for stomach cancer, about 11.1 % and 8.5% in stool hemocult test and colonoscopy for colon cancer, 13.5% and 9.3% in prostate-antigen test and rectal digit exam for prostate cancer, 36.4% in mammograpy for breast cancer, and 59.3% in Pap smear test for cervical cancer. And the higher proportions of having regular screening were 36.0% in Pap smear test for cervical cancer and 11.7% in mammograpy for breast cancer. The reasons related to not having screening tests were found that ‘seem to be healthy’ was 44.8%∼58.9% and the most common reason and the following was ‘not having opportunity for check-up’. The most common reason related to not having regular screening tests were ‘for the finding of previous check-up was normal’.

In this paper, we propose an effective global placement technique using quadratic programming(QP). In order to resolve cell congestion problem which is a drawback of QP based placement techniques, additional force and grid pre-warping technique are used. We devised a new density function for evaluating proper additional force which depends on density. Grid pre-warping technique relocates cells over entire area according to the relative ordering between coordinates of cells. Using the additional force obtained by the new density function and applying the pre-warping technique iteratively we obtained a well-distributed global placement. Mongrel which is a middle-down methodology based placer takes such a good global placement as an initial placement and produces a final detailed placement. Experimental results show that proposed technique outperforms the FM algorithm based global placement and are comparable with the well-known leading placers, FengShui, Dragon.

As creativity and problem-solving ability become core competencies, the main objectives of programming subjects in the elementary and secondary educational curriculum is 'computational thinking'. This goal can not be achieved at the level of understanding the characteristics of the programming language and the simple utilization abilities of the computer. The abilities to write algorithms and solve problems in real life situations using programming languages are required. In order to cultivate these abilities, the curriculum of the programming area was strengthened in the elementary and middle education curriculum, and the criteria for evaluating the achievement level were also prepared. However, the curriculum that can be used in actual education field is not yet established. In this study, we analyzed the researches on the existing programming curriculum and evaluated how well the curriculum meets the achievement criteria. Also, we can suggest the aspects to be considered in the study of programming curriculum and to verify whether the results of curriculum operation are in line with achievement criteria. In addition, future directions in elementary and middle school programming curriculum are suggested.

The aims of this study are to clarify the geomorphological development of a alluvial plain and discuss the vegetation environments and agriculture activities in the Wangpo-River alluvial plain at Neungsan-ri, Buyeo by analyzing geomorphological classification, sedimentary facies and age datings. The alluvial plain at Wangpo-River was formed by the influences of Geum-River with the sea-level rising during the Holocene. The basin of Wangpo-River consists of natural levees, back marsh-type alluvial plains, valley plains and hills. The natural levees by Geum-River largely distributes at the area where Wangpo-River flows to Geum-River and the alluvial plains at the middle and lower reach are the back marsh areas of Geum-River. Moreover, the area along Wangpo-River show higher contents of coarse materials and thinner peat sediments than the back marsh. The lower sandy deposits in the alluvium of Wangpo-River was formed with the influences of human in the Bronze Age during the sea level falling and the peaty deposits was formed due to the water level rising of Wangpo-River during the sea level rising in the early Iron Age.

The purpose of this study was to test the effects of practical reasoning home economics instruction on middle school students' views of home economics. Thomas(1986) categorized six alternative views of home economics as education for women, manual training, application of science, household management, family development, and an intervention. This study carried a quasi-experiment research with an independent variable of types of instruction and a dependent variable of views of home economics. The experiment was carried with the sample of 137 8th grade students in Gwangju area for ten class hours. Paired t-test was performed to examine the pretest-posttest differences of each experiment group and comparison group. The results showed that practical reasoning instruction improved level of the view of home economics as an intervention, and decreased level of the view of home economics as manual training. From the results of this study, conclusion can be made that practical reasoning home economics instruction is effective in changing to the appropriate views of home economics. Also it is expected that current Korean home economics textbook can lead to the views of home economics as household management and as family development.

National atlas map for provide various information is one part of National territorial Statatics Survey but National atlas map in 2004 year don't have stability and ability. National territorial Statatics Survey in 2005 years have octuple data compare with data in 2004 years but have only one map. One map is going to provide with stability and ability. We don't use DBMS, But We make a similarly struct in file based program. We programmed system of dynamic-linked data with spatial data. To dynamic-linked system, we make search engine to based index struct and make combobox search system. spatial data only have index codes(year, national terrial indicator, area). If spatial data request specfied data, search engine search index code and provide DB data. New system is middle step of using DBMS. We redraw map for display real Korea area (with dokdo). New map is shape and similar Korea map.

CHIME ages were obtained from monazites in metamorphic rocks from the Seosan and Siheung Groups in the Gyeonggi gneiss complex, Korean peninsula. Monazite CHIME ages range from 234 to 257 Ma, corresponding to the late Permian to middle Triassic Songrim disturbance due to the collision event between the North and South China blocks within the Gyeonggi gneiss complex in the Korean peninsula. The CHIME ages are consistent with the metamorphic ages from the Hongseong area (231 Ma, Kim et al., 2006) and the Odesan area (245-248 Ma, Oh et al., 2006b) in the Gyeonggi gneiss complex and are older than those from the Dabie-Sulu collision belt (220${\sim}$242 Ma, Yang or of., 2003; Liu et al., 2003, 2004) suggesting that the collision between the North and South China blocks had occurred earlier in Korea than China.
