The purpose of this study is to analyze the gap of private tutoring expenditure using data from 2001 to 2016 of Korean labor and income panel study (KLIPS). The final analysis target is about 1,300 to 1,800 households nationwide who participated in the Korean labor panel survey in each year. As a result of the analysis, the expenditure of private tutoring expenditure has been continuously increased since 2001, and it is analyzed that there is a large gap in expenditure of private tutoring even in the comparison of groups divided by the quintile. The spending gap on private tutoring expenditure in the first and fifth quintiles has increased steadily, reaching 11 times in recent years. By forecasting the polarization of private tutoring expenditure since 2016 using the Brown's smoothing method, it is highly likely that the polarization of private tutoring expenditure will be further expanded. The implications for preparing an alternative educational policy and suggestions of conducting a follow-up study for private tutoring expenditure gaps were also discussed.

It is important to design windows in a reasonable way considering the performance characteristics of the elements of the window rather than just to increase the thermal energy performance of the window. In this study, the Heat-transfer Coefficient as insulation performance of the windows and together with the grade of the glass's SHGC (Solar Heat Gain Coefficient) were analyzed to relate to the energy efficiency performance of the building by azimuth angle. Based on this basic study, the Heat-transfer Coefficient of windows and the SHGC rating of glass were applied to the unit plan of apartment building, and the Heating and Cooling Demand were analyzed by azimuth angle. Apartment plan types were divided into 2 types of Non-extension and extension of balcony. The designPH analysis data derived from the variant of the Heat-transfer Coefficient and SHGC, were put into PHPP(Passive House Planning Package) to analyze precisely the energy efficiency(Heating and Cooling Demands) of the building by azimuth angle. In addition, assuming the 'ㅁ' shape layout, energy efficiency performance and potential of PV Panel installation also were analyzed by floors and azimuth angle, reflecting the shading effects by surrounding buildings. As the results of the study, the effect of Heat Gain by SHGC was greater than Heat Loss due to the Heat-transfer Coefficient. So it is more effective to increase SHGC to satisfy the same Heating Demand, and increasing SHGC made possible to design windows with low Heat-transfer Coefficient. It was also revealed that the difference in annual Heating and Cooling Demands between the low, mid and high floor households is significantly high. In addition to it, the installation of PV Panel in the form of a shading canopy over the window reduces the Cooling Load while at the same time producing electricity, and also confirmed that absolute thermal energy efficiency could not be maximized without controlling the thermal bridge and ventilation problems as important heat loss factors.

The land under Japanese-type names remains in the Korean cadastral record as an official register due to land exploitation, land and field survey programs, and the forceful name-changing system of Japan during its colonial era. This research aims to find a measure to survey and organize such land. Research details are as follows. First, this research put together the purpose and status of land exploitation in the Japanese colonial era. Japan wanted to reduce its population through agricultural emigration of the Japanese and increase food supply by producing more crops in Joseon. Therefore, land of three southern provinces, the breadbasket of Korea, was intensively plundered. Secondly, this research organized how Joseon people changed their surnames into Japanese-style ones. The initially voluntary name-changing system became mandatory and about 3.22 million households (79.3%) reported the change of their names. Thirdly, this research established a process to survey land under Japanese-style names. Fourthly, this research yielded visible outcomes as a result of the pilot program. Especially, it revealed 718 lots as land under Japanese-style names and 8 lots as land under the names of Japanese. Fifthly, this research presented internal & external collaboration and cooperation measures for surveys.

The people of Silla was described as the descendants of Hwagwan(official of fire) on the tombstone of King Munmu(文武王), and Gim Yusin(金庾信) was described as the descendants of Shaohao Jintian(少昊 金天) and Huangdi Xuanyuan(黃帝 軒轅) on his tombstone. It says that the royal households of Silla and Gaya had common ancestor. Hwagwan was the official who took charge of fire management and the ritual for Antares(${\alpha}$ Sco) in ancient China. Hed founded State Ra(羅國). The name of Silla(新羅) means new State Ra, so he could become the ancestor of the people of Silla. He was the son of Zuanxu Gaoyang. State Gaya(加耶), the fatherland of Gim Yusin had been called Geumgwan-gug(金官國) which means the state of official of metal. Geumgwan was the son of Shaohao Jintian. Silla was the state of Hwagwan and the Gaya was the state of Geumgwan. Hwagwan, the founder of the royal household of Silla was the son of Zuanxu and Geumgwan, the founder of the royal household of Gaya was the son of Shaohao. Zuanxu and Shaohao was the descendants of Hwangdi, so Hwangdi was the common ancestor of Silla and Gaya. Finally Hwangdi became the same ancestor of Gim Yusin and King Muyeol(武烈王) who was the father of King Munmu. The tombstone of King Munmu and Gim Yusin manifests the union of the blood of Gim Yusin and King Muyeol. But it was not the fact but the rhetorical fiction.

In South Korea, the number of households that rear companion animal has been gradually increasing. With the rise of household dogs, the frequency of humans that are being bitten by another's dog has also increased. This type of accident, which is known as a dog bite accident throughout the United States. It can cause significant physical and emotional damage to the victims and may result in grave injuries or death. Dog bite accidents are serious public health problems and can cause immeasurable hidden costs to the community. South Korea has enacted several laws to address dog bite accidents, which include the Animal Protection Act, the Civil Act, and the Criminal Act. On March 20, 2018, the Animal Protection Act was amended to reinforce the current legislation. These amendments addressed the duty of care owed by a companion dog owner to society members and the punishment that an owner of a fierce dog would face in the event of a dog bite accident. Conversely, several states in the United States have enacted a single law that regulates the details regarding dog bite accidents, such as the type of dog or animal, the type of damage, the scope of compensation for damages, and the scope of recognition of liabilities. This paper is intended to review the present situation of dog bite legislation in several states in the United States, which have a variety of laws that address dog bite accidents, and compare them with current South Korean dog bite legislation. Through this research, this paper will discuss what issues may exist in South Korean's current dog bite laws, analyze the responsibility of companion dog owners, and provide solutions to any issues that are discovered.

Objectives: The purpose of this study is to empirically verify the difference between traditional gender role attitude and realistic dual earner attitude. Most preceding studies analyzed gender role attitude by summated rating scale while few studies have been conducted on the difference between traditional gender role attitude and dual earner attitude. Method: By using the 9th Korea Welfare Panel Data (year 2014), this study extracted households of married couples and with children in working age (18 through 64 years of age) who are the main subjects in work-family relationship. First, this study classified traditional group and modern group in their gender role attitude and passive group and active group in their dual earner attitude and by crossing these attitudes, drew out 4 gender role/dual earner attitudes. For analysis, this study investigated frequency of attitude types through descriptive statistics. By conducting ANOVA, study verified if there are significant differences in the satisfaction with family relationship depending on the types of gender role/dual earner attitudes. Lastly, study examined the effect of socio-economic status and demographic characteristics on the types of gender role/dual earner attitudes by conducting multi-nominal logistic regression analysis. Results: As the result of analysis, first, half of respondents belonged to 'equal-role-oriented type' who has modern gender role attitude and active dual earner attitude. However, there were not a few 'dual-earner-avoiding type' who has modern gender role attitude but passive dual earner attitude and 'incongruous attitude type' who has traditional gender role attitude but active dual earner attitude. Next, 'incongruous attitude type' had significantly low level of satisfaction with overall family life, relationship with spouse and relationship with children than other attitude types. Lastly, those whose incomes belong to poor strata, those who are high school graduates and lower, males and those who are over the age of 60 had significantly higher probability of belonging to 'incongruous attitude type.' Conclusion: The results of analysis demonstrate that the difference between gender role attitude and dual earner attitude is an important matter and since 'incongruous attitude type' exhibits low level of satisfaction with family relationship, scrupulous policy approaches are required for those who have high possibility of belonging to 'incongruous attitude type.'

In Korea, 'spoon class discourse' has attracted public attention in the press and among young people, which reflects that mass awareness that the class status structure is clearly rooted in the society becomes widespread. Although income distribution has been improved since late 2000s, it is interesting that Korean people's subjective perception concerning class mobility and social justice has been worsemed. By using the survey data on people's perception of opportunity inequality, this study finds that Korean people have by and large negative subjective awareness regarding socio-economic opportunity inequality, magnitude of opportunity inequality, and achievement by efforts, and that the degree of the negative perception is greater in accordance with the people's subjective identification. The regression analysis reveals that the social status of respondents and their parents(-), experience of discrimination(+), age(-), and high education of college and above (+) have consistent effect over socio-economic opportunity inequality, magnitude of opportunity inequality, and achievement by efforts with statistical significance. More concretely, as people have lower subjective status identification at the time of parent generation and their own generation, as they have the experience of discriminatory misconduct, and as they are young and highly educated, they have negative or pessimistic perception regarding opportuinity inequality. In addition, it is revealed that the unemployed and non-regular workers have significantly negative perception on socio-economic opportunity inequality, magnitude of opportunity inequality, while negative perception on the magnitude of opportunity inequality and achievement by efforts is noticeable among high and middle income households.

Small libraries have continued to be extended since 2013 enactment of regulations requiring establishment of small libraries in multi family housing complex not less than 500 households and the 'Living SOC Project' of national government. Gwangmyeong city designated the year of 2020 as the 'year of citizen autonomy' sharing the authority with citizens and publicly announced its plan to rapidly extend the living and cultural spaces as a part of that extension. Likewise, as the social environment and the need of users are expected to change, it seems that the small libraries in Gyangmyeong City must prepare a plan for practicing a long and mid term practices in responding to that change. Thus, this Study tries to make a suggestion for a plan for the policy for revitalization of small libraries in order to handle those changing social environment and the need of users. For this, a survey and in-depth group interview were conducted for the operators of the small libraries in Gyangmyeong City. As a result of this Study, the following policies are suggested: first, improvement of support system for improving operational system, strengthening of cooperative system of public libraries, and strengthening of role of public small libraries, strengthening of public characters of private small libraties and differentiated support through evaluation based on abilities; and second, it is necessary for utilization of circulating librarians and professional volunteers, sharing of materials through mutual lending of books, associate librarians having term of office and revitalization of small library conference by regions.

The concept of integrated pest management (IPM) first developed in the 1950s, and the concept of economic control via pest management was established in the 1960s. Research on IPM began in the United States and Europe, and IPM studies in Korea started with citrus insects and paddy field pests following the distribution of high-yield varieties of rice. Apple IPM in Korea began with research on pest control using chemical pesticides and pesticides resistant to insect pests, studies on the ecology of insect pests and their natural enemies, and the exploitation of sex pheromones on insect pests. Since the 1990s, IPM research and field projects have been carried out simultaneously for farming households. In the 2000s, the development of pest monitoring and forecasting models centered on mating disturbances, database programs for pests, and networks for sharing information. IPM technology has expanded via the development of unmanned forecasting systems and automation technologies in the 2010s.

In this paper, DLKF (Deep Learning Keypoint Filtering), the deep learning-based keypoint filtering method for the rapidization of the image registration method for remote sensing images is proposed. The complexity of the conventional feature-based image registration method arises during the feature matching step. To reduce this complexity, this paper proposes to filter only the keypoints detected in the artificial structure among the keypoints detected in the keypoint detector by ensuring that the feature matching is matched with the keypoints detected in the artificial structure of the image. For reducing the number of keypoints points as preserving essential keypoints, we preserve keypoints adjacent to the boundaries of the artificial structure, and use reduced images, and crop image patches overlapping to eliminate noise from the patch boundary as a result of the image segmentation method. the proposed method improves the speed and accuracy of registration. To verify the performance of DLKF, the speed and accuracy of the conventional keypoints extraction method were compared using the remote sensing image of KOMPSAT-3 satellite. Based on the SIFT-based registration method, which is commonly used in households, the SURF-based registration method, which improved the speed of the SIFT method, improved the speed by 2.6 times while reducing the number of keypoints by about 18%, but the accuracy decreased from 3.42 to 5.43. Became. However, when the proposed method, DLKF, was used, the number of keypoints was reduced by about 82%, improving the speed by about 20.5 times, while reducing the accuracy to 4.51.
