The purpose of this research is to examine generational distinctions of housing investment and household wealth for two different age cohorts - 'baby-boomers' and 'eco-boomers'. In so doing, national survey data of two different periods were analyzed and the primary results are summarized as follows; aggregate assets of both generations have risen, and the rising household debt for baby-boomers was related to loans for living expenses while eco-boomer's debt was ascribed to home-buying loans. In the midst of economic slowdown, the age cohorts had conservative asset allocation in preference for risk-averting investment like savings. The main purpose of saving and investment was distinctive across the groups? retirement for baby-boomers and home purchase for eco-boomers. Both groups prioritized reduction of household liabilities and also were cautious on investing in real estate. Still home-buying was considered to be an important driver for asset accumulation. While baby-boomers were unwilling to dispose any form of owned real estate, eco-boomers found it challenging to take on a long-term investment like home-buying, especially in economic uncertainties. Rather the young generation would diversify asset allocation with better-returning investment commodities like stocks, bonds and derivatives.

Water quality sampling surveys and continuous measurement of flow were conducted to identify wastewater flow characteristics for representative catchment of O and M treatment basins in A city. For HS-1 station representing commercial area, wastewater flow rises in the beginning of office-working hours, moves up and down within narrow range, and lasts till office-leaving hour, and falls gradually reflecting worker's returning home. However, in HS-2 station representing residential area, wastewater flow has two peaks, which are before office-going hour and after office-leaving hour. In residential area, the flow rate of weekends is higher than that of weekdays because it reflects population, being not contributed to generate wastewater during the working hours of weekdays, stay home and produce wastewater for weekends period. To determine the priority for rehabilitation of sewer system, infiltration rate was computed by dividing infiltration flow by mean diameter and total length of sewer, and HS-1 station ranked the first.

This study investigated the relationships between inter-cultural experience and socio-psychological adjustment to the current life among children who have refilmed from living abroad. The subject of research consisted of 102 boys and 110 girls from fourth grade through sixth grade who returned to their home country after living in a foreign correlation Data were collected from 5 elementary schools in Seoul. Descriptive statistics, t-tests, correlation analysis and regression were used for data analysis. The results of children's social-psychological adjustment were represented by 3 categories: school/friend relationship, stress/strain and language/learning. The following are the summarized results; First, girl students were more likely to adapt to school/friend relationships in Korea and had lower stress/strain than boys. Second, the children having shorter period of residence in foreign county, lower adaptation ability to different culture and extrovert personality showed higher socio-psychological adjustments after returning to Korea. Third, the adjustment to school/friends was influenced by period of residency in the foreign county, the experience of different culture, and extrovert personality. The experience of different culture and extrovert personality effected stress/strain, and the adjustments to language/learning were influenced only by the ewperiecne of different culture. Lastly, the experience of different culture was the most important variable influencing all 3 categories of socio-psychological adjustments.

Affordance is a kind of mental physiology, used by psychologist Donald A. Norman as a design idea, defined as "the property that something can directly and essentially provide something to a person or animal". This idea of returning to the essence and providing properties intuitively has a new guiding effect on product design. The purpose of this thesis is to take the theory of affordance as the basis of design concept, and redesign the shape of desktop lamps in small home appliances, so as to optimize the product shape. A product styling design method based on the concept of affordance is established through four major classifications of affordance, and a styling design scheme is completed using a tabletop luminaire in small home appliances as an example, and then a product styling design evaluation system is used to evaluate the new tabletop luminaire styling design scheme and the existing styling, and the evaluation results are analyzed. Finally, it is concluded that a new product styling design method based on affordance is constructed, and the feasibility and effectiveness of this method are verified, which provides ideas and theoretical basis for product styling design.

This article considers the meaning of 'Zainichi (在日)' expressed in epic poem Niigata (1970) written by Korean-Japanese poet Kim Shi Jong. Kim sets two points in his creation of poetry. One is summer of liberation released from Japanese colonial domination in 1945. The other is Japan where he lives as a Korean-Japanese. These two points have made him think about the meaning of living in post-colonial era and the national division of Korea, his home country. His thought like this is well expressed in his epic Niigata. Niigata was written in 1959 when the ship returning to North Korea departed from Niigata of Japan. However, Kim couldn't return to his home country at that time. He stowed away from South Korea to Japan in 1949. He participated in antigovernment activities occurred in Jeju Island to block the national division between the south and the north after the liberation in 1945, the so-called 4.3 incident. Besides, he was having conflict with the organization of North Korea at that time because it required a doctrinaire belief and creation in Korean. Kim was writing poems in Japanese and pursued the life of existence as a Korean-Japanese. Therefore, he decided to remain in Japan instead of returning to North Korea. Of course, he could not return to South Korea because he was a refugee. Kim imagined in Niigata, the place located in an extension of the 38th parallel and the spot of national division. He could not cross the division line when he was in his home country, but he could do it in Niigata through imagination. The life as a Korean-Japanese makes it possible. 'Zainichi', which means living in Japan, has been recognized as a worse situation compared to living in Korea. However, Kim changed his way of thinking. Zainichi can embrace South Korea, North Korea, and Japan. This is the very reason why he lives there as a Korean-Japanese. His thought like this is well expressed by symbolic representations and metamorphose as well as the imagination of spatial extension.

The materialism prevalent in the modern industrial society and concern for the destruction of nature have led people to long for the returning to nature and excite their nostalgia for old. These phenomena induced in modern fashion naturalism retrospectivism ethnicism and primitivism. In the following we present our findings in regard the roles and relationships of the tie dying with the modern fashion design. in regard the roles and relationships of the tie dying with the modern fashion design. The common basic themes are founded as follows; 1. Naturalism: The tie dying is from very old times and has evolved in many parts of the world producing their own natural designs and color. They bear the characteristic of nature; the pleasantness smoothness and complexity. 2. Individualism and hand made: No two items produced by the tie dying technique are identical even though they are similar by design and their individuality is to some extent determined by chance. The retrospetivism and individualism are themes relating to the modern fashion. 3. Ethnicism and primitivism: The tie dying brings up the 'ethnic and traditional' to us and their designs and colors present the new images of the ethnic and primitive influences to the modern designs. 4. Ecology recyle and grunge look: The tie dying represent the recycle of the used natural resources such as making the old cloths useful again in new forms by tie dying them. The old clothes thus restored show wrinkled untidy and somewhat loosely fit form. This image of 'grunge look' is one of the central theme of the modern fashion.

A bathroom in house has been stressed not only as a space for physiology and hygiene but also leisure and healthcare. However, the bathroom is the most likely space where an elderly person can have an accident and it is uncomfortable space for them because of their deteriorating physical ability. So the purpose of this study is to help the elderly use their bathroom conveniently by providing smart service. Therefore, we carry out 18 smart service patterns that contain assistive devices and sensors for bathroom. Considering applicability and frequency, from among these service patterns, we suggest 4 service patterns. First is a fall prevention service. This service helps elderly use the bathroom safely at night. Second is a getting ready to go out service. This service helps the situation that elderly use the bathroom after getting up in the morning. Third is a security service in daily life especially before or after meals. And final is a service regarding personal hygiene service after returning home. This service helps to shower or bathe after return home. These services have positive influence in medical expense reductions, good health care and self-reliance of elderly.

The purpose of this study is to present our elderly welfare policy and welfare facilities for the elderly and to propose the future direction of policy for the elderly with comparison to that of Japan. The comparative study results of Korea and Japan are as follows: As the basis of elderly welfare, care insurance for the elderly is now fixated in the two countries. On the other hand, for quantitative expansion in Korea, the quality level has been gone down. Due to qualitative evaluation, the growth of facilities has slowed and material welfare providers was also a decline in the number of operators. Two countries in the field of community welfare in recent years has been actively promoting. It is the most important to solve the social welfare problem with local councils who know the area, which is a part of the future to focus and to support. Due to huge construction investment of facility, there is the burden of operators. This facility is appropriate for an extension of the home. However, it is in the hard economic times. Until now, the number of people in a room is at least four according to the legal standard of Korea, there are a few private rooms. On the other hand, in Japan, unit-care was phased since 2002 and private rooms have been expanded. In Japan, health center for the elderly plays an important role with special elderly nursing home among facilities for the elderly. Health center provides services that are recovering, nursing, and caring to support independence for the elderly after acute phase of treatment. As treatment and care, the aim of health center is to return the elderly to home. On the other hand, there are a few health centers for returning the elderly to home in Korea. Furthermore, in Japan, a project for preventive care has been begun. The project is needed in Korea.

Background: About 60% of patients with epilepsy showed a variety of complications after returning home. The purpose of this study is to get further information and to help in the anesthetic management of the disable patients with epilepsy. Methods: After searching the outpatient anesthesia list of Seoul National University Dental Hospital clinic of the disabled from September 2010 to March 2012, we found total 83 patient cases who were taking antiepileptic drugs. A nurse of anethesiology department called to the patient's home after general anesthesia and got surveys with questionnaires form filled with complications at home. We enrolled total of 51 patients who agreed to participate this survey. And we also reviewed pre-anesthesia evaluation sheet, anesthesia record, and recovery and discharge record. Results: 11 of 51 (21.6%) patients had seizure convulsion at home within 1 weeks. 33.4% of patients who had at least once seizure attack per week had a seizure attack within 3 days. And 50% of once a month frequency patients had a seizure attack within 1 week. 33% of 1 - 3 seizure attacks per year patient group had a convulsion within 1 week. But there was no seizure attack within 1 week in whom had no seizure attack history during more than 1 year. Conclusions: After dental treatment, patient taking anticonvulsant have so many complications-especially seizure, more than we respected. We need more research about handle these problems.

Traveling salesman problem is to minimize the total cost for a traveling salesman who wants to make a tour given finite number of cities along with the cost of travel between each pair them, visiting each cities exactly once before returning home. Traveling salesman problem is known to be NP-hard, and it needs a lot of computing time to get the optimal solution, so that heuristics are more frequently developed than optimal algorithms. This study suggests a hybrid parallel genetic algorithm(HPGA) for traveling salesman problem The suggested algorithm combines parallel genetic algorithm, nearest neighbor search, and 2-opt. The suggested algorithm has been tested on 7 problems in TSPLIB and compared the results of existing methods(heuristics, meta-heuristics, hybrid, and parallel). Experimental results shows that HPGA could obtain good solution in total travel distance minimization.
