When the natural villages in Jeju province are incorporated into the district of city planning, they are considered to be a small-scale residential districts. Therefore, a garden city should be planned that considers the characteristics of the villages to implement an appropriate street system, to use the area effectively, and to harmonize the villages with the surrounding communities. There have been an especially large number of problems with the street system in the city of Seogwipo, which was notified as the area of natural settlement. This study analyzes the problems inherent in street planning and the present condition of roads whose construction has been postponed for a long time due to several problems including an inappropriately planned street system. Based on the research of various documents, a practical street system has been investigated. Most of the residents in natural settlement units demand use of the continued the existing roads as well as the implementation of an effective street system. They ask for street planning under which the involved construction would take only a short period of time and would result in only minimal damage to their existing properties. Therefore, the street system should be planned so as to preserve the nature-friendly features of natural settlements, their surroundings and tourism resources. Even after streets hwve been planned and their completion you has been established, the plan should be continuously evaluated, analyzed and compared with other alternatives. The street plan should continuously incorporate improvement measures which would satisfy various aspects of the street system including land use, traffic demand, and future population demands. Both the amount of money to be invested and economical efficiency should be considered for street planning since the street system has a great impact on many industries. Unnecessary costs related to excessive road construction should be avoided. The street network plan should also include the complete evaluation of the natural topography as well as the surrounding. Considering these views, the data concerning the current condition of the city and the related investigation play an important role in establishing a street plan. However, the investigation of future construction plans by the city is as of yet at a very early stage. Therefore, there is an urgent need for the investigational study of the current city development plans. The street system for the natural settlement area should be established only after the thorough investigation of all aspects of street planning. In addition, the plan should be flexible enough to consider the characteristics of Jeju.
Lightning data, observed from total lightning detection system (TLDS) of KMA, for the recent five years (2002-2006) have been analyzed for temporal and spatial characteristics of frequency, intensity, duration, and flash rate. Lightning frequency varies largely with years (most frequent in 2006) and the lightning during the summer accounts for 75% of total flashes and only 0.6% of lightnings strike in cold season. In rainy season (JJAS), the ratio of positive flashes to negative ones is as low as 0.15, but it increases up to 0.98 in February. The seasonal variation of lightning duration is strongly linked with lightning occurrences, whereas flashes rates show weak seasonal variability. In a daily scale, lightning, on average, occurs more often at dawn (2 am, 5-7 am) and in the mid-afternoon (15 pm), and the lightning at dawn (around 5 am) is most intense during the day. The western inland areas md the West/South Sea show high lightning density during JJAS, whereas eastern part and the East Sea exhibit a low density of lightning. Considering the low ratio of positive flashes (0.15) for the whole analysis domain during summer period, Chungnam and Jeonbuk areas have a high ratio of flashes over 0.4. However, these should be analyzed with much caution because weak positive cloud-to-cloud discharges can be regarded as cloud-to-ground flashes. The western inland also exhibits long annual flash hours (15-24). And the W3st Sea has high flash rates as a result of large density and low flash hours. The most frequent time of lightning occurrence over most inland areas lies between mid-afternoon and early-evening, whereas mountainous and coastal areas, and the northern Kyoungki and Hwanghae provinces show the maximum lightning strikes in the morning and at dawn, respectively.
Generally fairytales are recognized as very effective educational materials. However, some of them includes negative prejudices on stepparents, especially stepmother. These contents are very harmful to development and adjustment of children in remarried families. Moreover, not so many studies have been done that even the results were insufficient to not only practical but also academical needs. Therefore this study purposed to investigate the parent -and stepparent- figures perceived by children with the knowledge about the related fairytales. Specific research problems are as follows; 1. How many children do know the contents of the 4 related fairytales such as Snow Whit, Sindellera, Kongjui Patjui and Changwha Honglyun? 2. What are the parent -figures perceived by the children with the knowledge about the 4 traditional fairytales? 3. What are the stepparent- figures of the subjects? 4. Is the children's sex the statistically significant variable in their parent -and stepparent- figures? 5. Is the children's age the statistically significant variable in their parent -and stepparent- figures? 6. Is the their parents' educational level the statistically significant variable in their parent -and stepparent- figures? 175 boys and girls of age -9 and- 11 were selected from 2 primary schools in Seoul. All of them were from normal families. As the steadyselling books, 18 fairytales were chosen by 7 booksellers of large scale bookstores in Seoul. And then by 10 teachers and 10 literay persons, 4 Korean and foreign traditional fairytales were seleced at last. The questionaire of 5 subareas was developed and used as the research tools, in which include 40 items. SPSS/pc program were used for data analysis for frequency, percentile, mean, and t-test. The followings are the findings with cronbach α=.80 and .94 parent -and stepparent- figures respectively. 1)The contents of the 4 tradional fairytales were read already or wellknown, even if the children who didn't. 2)The subjects showed very positive their own parent-figures such as sweet, lovely, reliable, and true or good person. 3)The subjects showed very negative stepparent-figures in contrast. 4)They showed significant sex difference(p<0.5) in their own parent-figures. And girls were more positive than boys who were a little more positive(on insignifficant level) than girls in stepmother-figures. 5)All the subjects had positive parent-figures and negative stepparent-figures. 6)Their parents education level was no significant variable in the prediction of their parent -and stepparent- figures.

Konkuk University Hospital (KUH), which opened in September 2005, is currently categorized as a secondary hospital. Early on after its establishment, the surgical residents and nurses were relatively inexperienced in the treatment of stomach cancer. Therefore, the quality of surgery for stomach cancer at KUH may be different from that of the existing large-scale tertiary hospitals. The purpose of this study is first to investigate the clinicopathological characteristics of the gastric cancer patients at the KUH, and second to compare our morbidity & mortality rates with those of previous studies, and we also analyzed the risk factors of morbidity at the early stage of a training hospital. Materials and Methods: This study retrospectively collected the clinicopathological characteristics and the post-operative morbidity rates and mortality rates with using the electronic medical records of all the patients who went under a gastric cancer operation at KUH from September 2005 to April 2008. Results: The total number of gastric cancer patients who underwent operation was 201. The morbidity rate and death rate at KUH were 10.4% and 0.5%, respectively. The morbidity has increased with an older age. The other variables had no influence on morbidity. Conclusion: The morbidity rate, death rate and the clinicopathological characteristics of gastric cancer patients at KUH were similar to those of the previous reports. We found that age is the main factor affecting the morbidity rate after stomach cancer surgery. For further surgical qualification of stomach cancer surgery at KUH, it is necessary to collect the survival data of patients who undergo stomach cancer surgery.

The diagnosis of pattern identification in Korean Medicine depend on Korean Medicine doctor's experience and information. So, Pattern identification in Korean Medicine raise a question of objectification. This study is to standard stroke pattern identification in Korean Medicine. Weight of symptoms was given important(1points), very important(2points) by stroke specialist. So weight of symptoms is used two method. One is total sum and the other is total man. One had been compared Pattern identification between diagnosed patients by medical specialists and by applicated weight in case report form. The other had been compared Pattern identification between intersubjectivity by medical specialists and by applicated weight in case report form. It is 38%(total sum) or 40%(total man) concordance rate between diagnosed patients by medical specialists and by applicated weight in case report form. It is 82.4% concordance rate between intersubjectivity by medical specialists and by applicated weight in case report form. To acquire more concrete data on this theme, we need further and large scale of prospective researches.

In this study, we analyzed the erosion variation of beach area at Haeundae Beach after coastal improvement project using video monitoring system operated by the Coastal Erosion Monitoring (Ministry of Oceans and Fisheries). Haeundae Beach was well maintained and stabilized following large scale nourishment through coastal improvement project despite of seasonal fluctuations. However, multiple typhoons over the last two years caused beach stabilization patterns and seasonal fluctuations to lost equilibrium, resulting in rapid erosion. In particular, the sandy beach was eroded by typhoon Solic and Kongray in 2018 and failed to recover beach area in winter by seasonal fluctuations. And due to multiple typhoons in 2019, the beach area was reduced 9.5 % (12,607 ㎡) year-on-year. According to analyze the observed wave and beach area data in Haeundae, the tendency of erosion and sedimentation was influenced by seasonal incident wave direction for each section(west, center and east part). Therefore, to identify the causes of decreasing seasonal fluctuation characteristics and continuous erosion, hereafter, more precise monitoring of different factors are needed, such as the crest heights of submerged breakwater and its loss of function, and sand leakage to the outside around submerged breakwater.

To guarantee the long-term access to digital material, digital preservation needs to be systemized, and detailed investigation on cost elements of digital preservation should be done for the continued support of budget. To meet the needs in this area, this paper categorized the digital preservation cost into direct and indirect cost through deriving common elements used in prior research on this issue. For case analysis, two institutions, representing domestic University Library and National Library of Korea under large-scale digitization currently, are selected to analyze the current status of digital preservation and estimate the preservation cost. The case analysis shows the systematic preservation function should be performed to guarantee the long-term access digital material, even though a basic digital preservation is currently conducted. It was projected that the digital preservation cost for the two libraries, accounting for $11.8\%$ and $8.6\%$ of digitization cost, respectively, should be injected every year. However, the estimated figures are very conservative, because the cost for estimating the preservation function, such as installing digital repository and producing meta data, was excluded in the estimation. This proves that digital preservation is a synthetic activity linked directly and indirectly to various activities from production to access of digital object and an essential costs that should be considered from the beginning stage of digitization project.
The purpose of this study was to help improve the quality of education to keep up with fast-changing environments in educating sector. Relevant literature and data were reviewed, and the subjects in this study were dental hygiene juniors at seven two-year colleges in the Seoul metropolitan area and other regions, on whom a survey was conducted for about three months from August through October, 2004, to assess their satisfaction level with their major and educational environments. And it's concluded that in order to attract more new students and foster qualified students, dental hygiene practice labs should be improved on a large scale, and that there should be a great deal of investment in teaching facilities. The major findings of the study were as follows: 1. As for satisfaction with major choice, 57.5% of the students investigated, the largest percentage, expressed satisfaction with their major. 27.8%, the second largest group, found their choice not to be bad. 2. Regarding satisfaction with the state of practice labs, 41.9% were pleased with practice labs. This rate was quite lower than that of nursing students, as 64.2% of nursing students were pleased with their practice labs.7) 3. As to satisfaction with individual practice labs, oral prophylaxis labs were considered most satisfactory, as 53.9% were satisfied with them. Digital radiation labs appeared to be satisfactory the least, which made 77.0% dissatisfied. 4. Whether there were any connections between their working experience as a clinical worker and satisfaction level was investigated. In terms of their satisfaction with major choice and the state of practice labs, the students who had ever worked as a clinical worker were relatively pleased with the state of practice labs. As for satisfaction with each practice lab, those who had ever served as a clinical worker before being admitted into college expressed more satisfaction with radiation practice labs(p<0.05) and digital radiation labs(p<.05) than the others who hadn't. The gap between the two was statistically significant. 5. In regard to the causes of dissatisfaction with practice labs, 93.7 and 80.0% were respectively dissatisfied with digital radiation labs and basic dental hygiene labs because their colleges were devoid of those labs. 51.6%, the largest group, found oral prophylaxis labs unsatisfactory because of their frequent breakdown. In the event of most of the other practice labs, the greatest percentage were discontented due to a shortage of equipment.

In order to understand the population dynamics of red tide dinoflagellate Noctiluca scintillans, we examined its hydrographical and bio-ecological characteristics at 19 to 20 stations of Gwangyang Bay during all four seasons from 2010 to 2012. During the 3-year period, N. scintillans was seasonally abundant during summer with water temperatures ranging from $15^{\circ}C$ to $22^{\circ}C$ and salinity ranging from 25 psu to 30 psu. On the other hand, N. scintillans population density significantly decreased in spring, fall and winter, although they were present even in lower temperatures (< $4^{\circ}C$). However, high water temperature (> $27^{\circ}C$) and low salinity (< 12 psu) led to the disappearance of N. scintillans population. Chl-a concentration in winter, spring and fall was positively correlated with N. scintillans population density, whereas the N. scintillans population was negatively correlated with Chl-a concentration in summer. This implies that densities of prey population such as diatoms are one of important contributing factor for maintaining abundance of N. scintillans in winter, spring and fall and for increasing abundance of N. scintillans in summer. During summer season, bio-accumulation of N. scintillans population by the wind from southwest is also considered to be a key factor in triggering the formation of large-scale blooms in Gwangyang Bay.
Purpose: The purpose of this study is to examine and improve the issues related to National Safety Inspection currently operation and reform the system for response to various disasters. Method: For the completion, this study established theoretical background using materials related to National Safety Inspection and identified the issues using the open statistical data for National Safety Inspection to suggest the improvement plans. Results: National Safety Inspection has been operating a complete large-scale inspection on risk factors in cooperation with the central government, local governments, and citizens since 2015 to remove various disaster factors neglected in people's daily lives. Operation of National Safety Inspection had positive influence in preventing major disasters. However, inefficient activity is pointed out due to issues related to cooperation with other institutes, limitation for citizen's positional role, and superficial inspection. Conclution: To solve this issue, this study proposed strengthening of communication activity with disaster institutes, strengthening of efficiency through citizen participation by type, and actualization of checklist used in National Safety Inspection.
