This study was conducted in order to investigate how a Problem-Based Learning (PBL) program titled(called) 'Designing Safe and Strong Bridge' effects scientifically gifted students' scientific attitude, scientific career orientation and leadership. The participants were 19 scientifically gifted students in the second grade in C high school in Gyeonggi province; they were selected by participation in the tri-level gifted students identification step. Before and after 14 units of the program, the participants were asked to take tests about scientific attitude, scientific career orientation and leadership and to write a review about the PBL program at the end. The major results of this study are as follows. First, participants' scientific attitude was statistically significantly improved after the PBL program (p<.05). In the sub-domain of this area, six parts excluding the part of openness were significantly developed. Second, the degree of scientific career orientation was statistically significantly improved after the PBL program (p<.05). All 4 sub-domains in the degree of scientific career were significantly developed. Third, all of leadership scores were statistically significantly increased after the PBL program (p<.05). In the first factor, the parts of inner and inter personal characteristics were significantly developed. According to their post-program opinions, participants developed in terms of all the secondary factors, such as ability of interpersonal relation, consideration for others and groups, responsibility for the task, confidence and vision, during the process of PBL problem-solving in the small group work.

Film festival is a cultural event, which would be held for various purposes. This study was to find out the effects of visitors' demographic characteristics and Jeonju International Film festival images upon their general satisfactions, focusing on the 10th Jeonju International Film Festival. The results are as following. First, 20's(year), Student(job) and Less than 100(income/a month) had a majority in the demographic characteristic. It is needed to develop various programs and events targeting for these groups. Second, it resolved 11 questions in all into 3 factors, which is named as 'Administration', 'Facility', and 'Contents'. Specially We need to develop events and programs for teens. It verified that visitors satisfied far more as they were provided with comfortable theater, various facilities and events, etc. It also proved that the service of giving useful informations met visitors' satisfaction. But as the demographic characteristic showing, visitors dwelling near Jeonju were fewer. It is required for a program to enhance the peculiar qualities of the city, Jeonju and then to promote the participation of local people. It is necessary for the host organization to secure its identity including peculiar subjects differentiated from other film festivals for the purpose of establishing itself as a worldwide event.

Due to the latitudinal location of Korea, the seasonally frozen ground has been focused on as research topics such as the frost heaving under the asphalt road rather than the permafrost ground. However, the recent construction of the second Korean Antarctic research station, the Jangbogo station and the participation on the development of the natural gas pipeline in Russia arouse the research interests on the behavior of the permafrost ground. At the design process of the geotechnical structures on the permafrost ground, the evaluation of the creep characteristics of the frozen soil is very crucial. Since the domestic specification on the frozen soil testing does not exist currently, it is necessary to evaluate the creep characteristics of frozen soils systematically with regard to the affecting factors. Therefore, the creep characteristics of the frozen specimens of dense Jumoonjin sand were evaluated under various loads at -5 and $-10^{\circ}C$. Based on the test results, as the load became close to the strength and the temperature became lower, the duration of the secondary creep became shorter and more distinct tertiary creep responses were observed.

This research was carried out to estimate annual erosion and retreat rates by using datum-point and to identify the characteristics and causes of seasonal variations of sea-cliff slope in Pado-ri, Taean-gun. In the result, the erosion and retreat rates of sea-cliff were increased from spring to summer. The rates were increased rapidly between August and October, caused by the effects of extreme weather events such as severe rainstorms and typhoons, etc. Since then, the erosion and retreat rates of sea-cliff were decreased gradually, but the rates were increased again in winter due to the storm surge and mechanical weathering resulting from the repeated freezing and thawing actions of bed rocks. The factors that affect erosion and retreat rates of sea-cliff include the number of days with antecedent participation and daily maximum wave height. In particular, it turned out that the erosion is accelerated by strong wave energy during storm surges and typhoons. The annual erosion and retreat rates of study area for the past two years(from May 2010 to May 2012) were approximately 44~60cm/yr in condition of differences in geomorphological and geological characteristics at each point. These erosion and retreat rates were found to be higher than results of previous researches. This is caused by coastal erosion forces strengthened by extreme weather events. The erosion and retreat process of sea-cliff in the study area is composed by denudation of onshore areas in addition to marine erosion(wave energy).

In this study, we empirically investigated the antecedents of crowdfunding success in the arts and cultural field using the case of Tumblbug in Korea. We collected data on 494 projects listed on Tumblebug in the arts and culture category that includes feature film, documentary, short film, animation, and Web series, as of June 2018. We analyzed the factors associated with the final amount raised via crowdfunding on Tumblbug using the hierarchical regression method. We find that the social capital accumulated by a focal entrepreneur (i.e., the proposer/designer of a focal project) through prior participation in other related projects and social communication activities carried out during the funding period, respectively, have positive effects on the final amount raised. More interestingly, we also find that the intensity of social communication plays a central role in the funding success of arts and culture-related projects by supplementing the lack of the entrepreneur's social capital and the reward features including a given project.

Korean Youth are facing diverse problems. For-instance Korean youth are even called '7 given-up generation' which indicates that they gave up marriage, giving birth, social relationship, housing, dream and the hope. From this point, the study concludes that the influential factors of the alcohol problems of youth should be studied based on the eco social perspectives. And it adopted data-mining methods, using SAS-Enterprise Miner for the analysis, targeting 2538 youths. Specifically, the study analyzed and chose the most predictable model using decision tree analysis, artificial neural network and logistic analysis. As the result, the study found that gender, age, smoking, spouse, family-number, jobsearching and economic participation are statistically significant determinants of alcohol problems of youth. Precisely, those who are male, younger, have the spouse, have less family number, searching jobs, have more income and have the job were more prone to have the alcohol problems. Based on the result, this study proposed the addiction problems targeting youth and etc. and expect to have the contribution on implementing procedures for the alcohol problems.

The national family planning program in Korea, which was instituted as an integral part of the nation's economic development plans since 1962, has contributed greatly to a reduction in the fertility and population growth rate. The total fertility rate dipped from 6.0 births per women in 1960 to 2.0 in 1985, and the population growth rate rom 2.84 percent per year to 1.25 percent during the same period, while the contraceptive practice rate for the 15-44 married women increased from 9 percent in 1965 to 70 percent in 1985. Study findings indicate that the fertility reduction in the past 26 years is largely attributed to the virgorous implementation of the national family planning program, rising age at marriage, wide-spread use of induced abortion, and the changes in attitude regarding the value of children that came into being in the wake of the rapid socio-economic development over the period. Among the strengths of the national family planning program are the following : 1) a pluralistic system of program manageent with active participation of various government and voluntary organizations, 2) utilization of a large corps of family planning field workers to conduct face-to-face communication and motivation activities, 3) use of private physicians with government support to provide contraceptive services, 4) a systematic program management system including program planning of traget allocation, evaluation, and supervision with a broad MIS and award system, 5) numerous incentive and disincentive schemes for stimulating the small family norm and contraceptive use, and 6) strong commitments to the family planning program by political leaders. The new demographic targets during the Sixth Five-Year Economic and Social Development plan period(1987-91) have been set for a further reduction in the population growth rate to 1.0 percent by 1993, assuming that the TFR will decline to 1.75 level in 1995. This target is, however, not easy to achieve due to anticipated unfavorable factors like the strong boy preference, high discontinuation rates of reversible contraceptive methods, fertility termination-oriented contraceptive use, a plateau level of contraceptive practice rate that has mostly accounted for a sterilization, shortened length of birth intervals, and the changing patterns of contraceptive mix. The recent changes in contraceptive and fertility behaviors clearly indicate that the past quantity-oriented management system of the national program should be redirected toward a quality-oriented approach. Particularly, program efforts should be expanded to recruit new contraceptive users in the 20s of younger age groups, both for birth spacing and controlling their fertility since the women aged 20 to 29 account for more than 80 percent of the total annual births in recent years. In addition, the current contraceptive fee system of the national family planning program should be gradually shifted from free contraceptive services to a acceptor's charge system, and the provision of contraceptive services through the medical insurance system, which will cover the entire population by 1989, should be accelerated as a means of integration of family planning program with other health programs.

Given the rapid development of information and communication technology (ICT) and the deepening of the information gap phenomenon in the context of the COVID-19 pandemic, researchers and practitioners need to understand the changing perceptions of new phenomena such as COVID-19 information gap on the existing information-vulnerable population. In this study, an empirical analysis was performed with the digital information gap survey data in 2020 to understand the potential impact of COVID-19 on the information gap according to the information-vulnerable class. This study is to verify the effect of information gap, marginalized groups, gender, and major factors of information services (contents, social relations, life services, information production, networking, social participation, non-face-to-face services) on the change in perception of digital information technology after Corona. Hierarchical regression analysis was performed. As a result of the analysis, it was found that the higher the content, social relationship, life service, networking, and digital non-face-to-face service, the higher the change in perception of digital information technology after Corona. Therefore, in light of the evolving phenomenon of COVID-19, it is considered that the government needs to provide education and training to strengthen the capabilities of the information-vulnerable class in order to resolve the digital information gap.

In this study, using the raw data of the 7th Food Consumption Behavior Survey(2019), compare and analyze what factors affect the food delivery service and take-out food expenditure of single-person and multi-person households. It was found that women(especially women in single-person households), have a high tendency to pursue safety preference versus price. In the future, Korea's population structure is expected to steadily increase single-person household and elderly households, and women's participation in economic activities is expected to continue to increase. In addition, the food delivery market has more than doubled compared to the previous year in 12 cities and provinces out of 17 cities and provinces nationwide with Covid-19, especially in the non-capital area, making it has become a universal service nationwide. Therefore, the growing home meal replacement market needs marketing strategies to secure and emphasize food safety.

The purpose of this paper is to investigate the impact on self-reliance and satisfaction of participants participating in the self-sufficiency business program of the Ulsan Metropolitan Regional Self-Sufficiency Center. A self-filled questionnaire was surveyed on self-sufficiency participants in five Borough and Country in Ulsan for 4 weeks from September 1 to 30, 2020, and final 233 copies were used in the actual analysis. As a result of the study, first, the percentage of positive responses of the participants was found to be good at 71.7%, for questions on the degree of support to the government, local governments, and administrative welfare centers. Second, in response to a system or service that would like to be supported or needed in the future, support for living expenses and support for health and medical expenses appeared and as a result of gender difference analysis, it was confirmed that there was a significant difference between support for children's education expenses and support for housing funds. Among the factors of the participant's psychological self-reliance(self-control, confidence, and willingness to work), the factor of self-control was the most significant factor, followed by confidence and willingness to work. Overall satisfaction with work was the highest among 9 satisfaction items such as salary and working hours.
