Marriage Immigrants have greater impact on local communities than migrant workers and foreign students, all the more because their children are relatively more important. Therefore, this study aims to inquire into the fundamental cause on the choice of residential location of marriage immigrants. Residential segregation is often considered to be one of the social problems that intensify locality of residential district. Although migrant workers and foreign students cannot freely decide their residential location at the outset, they could change their residence later on. However marriage immigrants are not free from the residential location choice continuously. The intentional(involuntary) residential segregation brings differential residence of marriage immigrants. The residential segregation of marriage immigrants is concerned with the close relationship of their ethnic background and the community characteristic with focus on Vietnamese and Filipino. The results of this study could be used basic guideline for community development policy for marriage immigrants.

Autonomous vehicles are the 4th industrial revolution that utilizes artificial intelligence(AI) and superconducting technology, and is a world-wide investment and research project. However, a Uber vehicle under test in Arizona, USA, was accidentally killed by pedestrians crossing the road in the dark night, and accidents occurred when the Tesla vehicle was exposedto the backlightof the sun. These problems were caused by misunderstandings and choice about sensors mounted on autonomous vehicles due to bad weather such as snow, rain, and sunlight. In this paper, we analyze the composition of the autonomous vehicle and the cause of the accident, and consider the criteria that should be judged in case of emergency in which human accidents may occur. This paper analyzes the composition of autonomous vehicles and causes of accidents, and considers the criteria that should be choice in an emergency where an accident may occur.

The purpose of this study is to find a reasonable solution that is compatible with the government's policy on calming the overheated housing market and the needs of prospective home buyers. For this purpose, this study analyzed the current state of the housing market and looked at the root cause of the people's desire to purchase housing. And this study suggested the need to introduce a super-long-term mortgage system that can help people choose whether to own or rent a house in accordance with individual preferences. The super-long-term mortgage system would be useful in that the majority of people who currently use mortgages prefer long-term loan products and that it could provide a chance to "get their own homes" by easing the monthly repayment burden for those who want to have homes. If the system is introduced in the future, it is necessary to make efforts for stable operation such as risk-hedge. In particular, the government should apply a limited application to end-users so that they can curb rising housing prices and contribute to stabilizing housing prices.

Orthodontic treatment is obviously the first choice to get aligned teeth cause of conservative treatment. But it is impossible to get highly esthetic result only orthodontic treatment in case of peg lateralis, discrepancy tooth size, discolored teeth or fractured teeth. As all treatment does, especially in esthetic treatment it is always required interdisciplinary diagnosis and treatment plan; orthodontics, periodontology, prothetics, implant therapy. As also, the treatment should be maintained long-term treatment with stable and harmonious state by esthetic satisfaction and functional occlusion those who needs various dental care as interdisciplinary treatment. This case is the laminate treatment with the orthodontic treatment on 37 ages/ Female patient who has cross bite at anteriors and premolar area and abrasion on centralis at right maxilla. By orthodontic treatment aligned teeth positions, it makes functional occlusion. As laminate treatment with minimum teeth preparation is able to release anterior esthetics.

Excessive crown height space increases can cause crestal bone loss and screw loosening after prosthesis is placed. Milled bar and implant overdenture can be used as a treatment method for partially edentulous patients who have severe alveolar bone loss and excessive crown height space. Milled bar can provide primary splinting effect and stability between implants. Also, milled bar with additional retention device such as Advanced Dental Device-Treatment Of Choice (ADD-TOC) and magnet can provide additional retention force for implant overdenture. In this case, the patient has a partially edentulous mandible that has severe alveolar bone loss and multiple number of teeth loss after excision due to leiomyosarcoma. Because of the long-term loss of mandibular molars, the opposing teeth were extruded. Maxillary left molars were corrected to the occlusal plane through molar intrusion, and mandibular left molar region were treated with implant overdenture, using milled bar with ADD-TOC and magnet after implant placement. The clinical result was satisfactory on the aspect of esthetic and masticatory function.

This paper aims to examine the effects of homeownership and residential types on the economic values of urban green spaces. Green open spaces as public goods provide positive externalities that are comprised of pecuniary and technological externalities. Seoul, South Korea, is used as a case study using choice experiments, with split-sample online respondents of 1,000. The study results evidenced that the differentiation between the two types of externalities is imperative for equitable provisions and efficient management of various urban open spaces. There is a positively significant and substantial impact of homeownership for apartment dwellers, ceteris paribus, but not for house dwellers. For apartments, the efficiency loss can be reduced by increasing green spaces up to the critical point where the marginal cost is at equilibrium with tenants' marginal values. For non-apartment houses, it is not homeownership but the monthly household income that has a significant impact on the amenity value. In general, public benefits from green spaces are equivalent to 16% to 33% of the current residential prices on average for a view or access. Different residential types do not cause a significant impact on the access values. Residential profiles for green spaces were developed, together with tailor-made policy suggestions.

The purpose of this study was to determine the leading causes of choosing to be single through in-depth interview. In the study I applied Hermeneutic Phenology to clarify the relationship between the past experiences and values of the subjects. I analyzed the leading causes that have drawn them to stay single, and the gender differences on the two subjects. The causes of being single were divided into two categories; personal factors and socio-environmental factors. The personal factors were standard value by birth order, expectation from parents, overcoming economic difficulty, and lack of interest toward the opposite sex. The socio-environmental factors were achievement at work, and ease of living. Staving single is not a special way of life. As found in the study, the cause of being single is not determined at birth, but rather results from being raised to be single in a way. The main cause of being single was basically based on the environment in which they were raised including parents' attitudes, economic situation, and sibling order We are living in a society of diversity. Being and staying single is a personal choice, that is one aspect of diversity. Therefore we need to widen our vision to accept the single life as one of the normal life styles and one for special treatment. We have to approve of other people's life styles as long as of causes no harm for the development of society. On the other hand, we need to be more serious about the family itself and having family. Finally I think we need to develop various family programs targeted at a diverse range of families rather than only at the normal family.

Renovascular hypertension results from a lesion that impairs blood flow to a part of or all, of one or both kidneys. Renal artery stenosis is the major cause of renovascular hypertension and the most common cause of treatable secondary hypertension. Recently, percutaneous transluminal renal angioplasty(PTRA) with or without stent placement, has become the preferred choice for correcting symptomatic renal artery stenosis since it is less invasive than surgical reconstruction. PTRA with balloons designed for the dilatation for the dilatation of the coronary artery can be tried in small sized renal artery stenosis. We report a case of renovascular hypertension in a 13-year-old male who had small sized renal artery stenosis. Hypertension was controlled by PTRA with balloon dilatation.
