In this paper, firstly, performance degradation due to the Private Distributed Reservation Protocol (DRP) conflict problem caused by devices' mobility is analyzed. And a novel relay transmission protocol combined with Private DRP conflict resolution is proposed to overcome the performance degradation at Private DRP conflicts. In order to give the loser device due to Private DRP conflicts another chance to maintain resources, the proposed relay transmission protocol executed at each device helps the loser device reserve another indirect link maintaining the required resources via a relay node.

In general, IoT(Internet of things) designate the intelligence technologies and services which interact all necessity information between human and things, things and thing and things and systems with all things connecting through the internet based. The smart home in present of IoT environment fuses the daily supplies/equipment which needs to use for the private life with the internet of things that is the fruit of the converged business through all most private consumption related in vastly. The concept of smart home has been built around early 2000s due to the spread of high speed internet and advanced of smart electronics and internet, furthermore influencing by the enhancement of wireless network and smart devices, it is advanced as a smart home within the internet of things environment. Smart home service inside the house which most closely implemented with personal life is being developed and advanced in various forms. These developments may exert a positive effect, but if it does not resolve the security issues for the smart home service, then it may cause a big plague of privacy and personal life.

This paper explores factors associated with multiple concurrent care and education arrangements in early childhood in South Korea. It draws on a subsample from the Korean Longitudinal Survey of Women and Families. Results show that about one-fifth of the families utilized multiple arrangements for their first preschool child. The primary non-parental option in multiplicity was nurseries or kindergartens. Home care and education options such as home study materials were found to be most prevalent secondary non-parental option, followed by services at private institution as well as relative care. Children's age, care cost, non-parental care time and time constraints were found to be positively related to the incidence of multiplicity for the first preschool child while family income and cost constraints were negatively associated. As a secondary option in the multiplicity, services at private institutions increased with children's age, care cost and when the grandparents live far from the parents' house. Home care and education utilization was found more among mothers with low degree of time constraints. Utilization of relative support decreased with the children's age and meant lower care cost and increased with mother's employment, fathers' education, family income, cost constraints and when grandparents live nearby. This paper, based on the associated factors, suggests how issues of children enrichment and constraints might be related to the multiplicity.

The purpose of this study was to examine the differences of self-confidence and satisfaction level in teaching home economics between home economics majored teachers(HET) and other subject majored teachers(OST). The subjects of this study were 192 home economics teachers randomly selected from 96 middle schools all over the country. The data was collected from 16, september to 12, October, 1996, and was analyzed with descriptive statistics, crosstables, and t-test using SAS program. The major finding were as follows: 1) In general, home econimics is taught mostly by OST in boy' middle school. 92% of OST is employed in boy' middle school and 89.13% of them is employed in private boy' middle school. 2) OST had less in-service experiences than HET on sixth revised curriculum, and had lower recognition than HET on the goal, content, teaching method, evaluation of home economics. 3) There were significant difference on the level of self-confidence and satisfaction in teaching home economics between HET and OST.

Considering the current rise in elderly population, institutions and facilities caring for the elderly are currently unable to satify the growing needs of the aged wanting the better qualities of life. Therefore, this study will analyze institutions and policies for the elderly in Japan, which has already experienced the rise in elderly population about 30 years earlier than Korea. Because the living conditions of Japan is somewhat similar to that of Korea, analyzing its solutions, both governmental and private, will help better understand the current situations of Korea and possibly offer guidelines as to better serve the growing demands of the aged. In Japan, the social welfare policies directed at caring for the elderly are mainly directed by the government: however, the private services tend to be more adroit at meeting the ever-changing demands of the elderly. Incidentally, the privately owned elderly homes of Japan are a major part of so called the "Silver Industries". The elderly home that are run by private corporations consititute 50 percent of all private institutions for the elderly. These homes tend tobe situated in a city, or near a city environment, serving 25 to 99 people. The types of such homes can be classified from A to D,E,F, reflecting the various services offered by such homes meeting the various demands by the elderly populatiov. Analyzing the social tred of Japan for theelderly, it can be said that the responsibility of the elderly should not only be relied upon the government, but to the society as whole, both public and private. The ever-changing demands of the elderly, wanting better qualities of life, can be better served by systematic analysis of the demands and the various solutions to such demands. Also, the necessary governmental policies in support of elderly welfare, will be needed.be needed.

Relationships between socio-demographic variables and parents' education invest-ment motivation variables and extra-class private education expenditures were examined using a sample of 602 households in Inchon Korea. Tobit analysis was used. Singal-cognitive motivation parents' duty motivation household income housing asset father's occupation class and number of children had significant effects on extra-class private education expenditures on general high school students. To alleviate overspending in extra-class private education diploma pursuing society has to be changed and formal school education need to be properly functioning. Finally parents seek new child education paradigm for the creative labor demand in the next millenium.

In Korea home economics in the secondary school level was only taught to girls until 1995. So. home economics education only for girls was criticized to sexist education by the feminists. According to the 6th revision of curriculum. home economics has been taught to girls and boys. But some of curriculum developers raises another questions on home economics education. They argue that home economics is a subject which prepares students for the demand of their day-to-day lives. but they can manage their lives well without school learning. The purpose of this study is to explore the educational values of home economics in secondary education from the gender-sensitive approach. For this study, a literature survey on the nature of home economic education in secondary education and the content analysis on 12 secondary school textbooks of Home Economics were employed. The results are as follows : First, the educational values of home economics education should not be underestimated. The aims of home economics education is to help students grew into a independent person by managing their daily lives. The home is charged with fostering a side of our life which we might call Personal, private. intimate and nurturing. The management of the home needs good skills and attitudes. and many knowledges on the child rearing, family relation, marriage, love and sex, which can not be successfully acquired without school learning. And home economics education for boys and girls can help break down the barriers between the sexes because it can change the attitudes of students regarding the private sphere. which is traditionally where women have worked. Second. most of contents of Home Economics were composed of the women-oriented contents. There was a trend still describing that domestic labor mainly be carried out by mother. And the ideas that only the family consisting of two parents and their children is normal were founded. Finally directions of development of the Home Economics Education are suggested.

In the Mobile IPv6 (MIPv6) protocol, a mobile node (MN) is a mobile device with a permanent home address (HoA) on its home link. The MN will acquire a care-of address (CoA) when it roams into a foreign link. It then sends a binding update (BU) message to the home agent (HA) and the correspondent node (CN) to inform them of its current CoA so that future data packets destined for its HoA will be forwarded to the CoA. The BU message, however, is vulnerable to different types of security attacks, such as the man-in-the-middle attack, the session hijacking attack, and the denial-of-service attack. The current security protocols in MIPv6 are not able to effectively protect the BU message against these attacks. The private-key-based BU (PKBU) protocol is proposed in this research to overcome the shortcomings of some existing MIPv6 protocols. PKBU incorporates a method to assert the address ownership of the MN, thus allowing the CN to validate that the MN is not a malicious node. The results obtained show that it addresses the security requirements while being able to check the address ownership of the MN. PKBU also incorporates a method to verify the reachability of the MN.
