The purpose of this study was to obtain a fundamental data for developing a policy concerning women and child rearing and a parent education program for young parents who are around their childbirth, a period crucially important both for the parents in terms of the role adjustment, career management, and family finance, and for the infants in terms of its physical and psychological well-being. The subjects were 509 mothers before and after childbirth currently living in the Metropolitan City of Daejeon. Data were obtained through questionnaires and interviews in two major areas of pregnancy-delivery-childcare and parent education. Data were analyzed using SAS, mostly through frequency analysis, percentiles, t-tests, and F-tests. Results of descriptive analyses were organized along the following areas and issues: Pregnancy(family planning, regular check-ups, difficulties, prenatal education, costs, etc.); delivery(type of delivery, delivery related experience, costs, clinic/medical institute of choice, worries/problems, help/supports, etc.); postpartum care(place, kinds of help and helper, costs, postpartum care facilities, etc.); childcare circumstances(place, carer, time schedules, childcare centers or facilities feeding and weaning, etc.); husband's attitudes and involvement in the overall process; working mothers(maternity leave, temporary retirement for child rearing, etc.); and, parent education(family planning, pregnancy, delivery, postpartum care, child rearing, areas or issues needing parent education, facilitative and hindering factors to ideal parenting, etc.). Differences between groups of pregnant mothers and postpartum mothers, working- and non-working mothers, groups of different income levels, mothers and fathers of different educational levels, mothers of first pregnancy(or childbirth) and experienced mothers were also analyzed. Several conclusions with suggestions were drawn in relation to the need for strong implementation as well as developing of policies on women and childcare and for developing a new parent education program for parents before and after childbirth.

This study is about the change in the importance of shopping value for beauty products of social commerce due to the social crisis or risk caused by COVID-19. It was analyzed focusing on whether the importance of shopping value changed before and after COVID-19. We checked the importance of shopping value after COVID-19 through the AHP results of previous papers before COVID-19, and analyzed the importance by adding variables of risk reduction behavior and delivery convenience according to the situation of COVID-19. The AHP method was used to check the change in the importance of shopping value before and after COVID-19, and the study was conducted using 48 data. The results were as follows. As for the importance of shopping value of social commerce beauty products, it was ranked in the order of time convenience, convenience of delivery, third-ranked trust business operators, fourth-ranked economic aspects, fifth-ranked decision support, sixth-ranked risk reduction behavior, and seventh-ranked business reputation. Compared to previous studies, decision-making support, which was in the second place, fell to the fifth place. This result was confirmed to be a drop in ranking due to the improvement of delivery convenience due to the influence of COVID-19. In addition, in the case of beauty products, it was confirmed that risk reduction behavior related to COVID-19 infection is not a key factor in shopping value. These results confirmed changes in the importance of shopping value compared to pre-COVID-19 studies, and in the case of product groups other than beauty products, further studies are expected as there is a possibility of other results.

Buddhism that has arisen in India began to build the Stupa to enshrine body and Sari of Buddha as an object of worship. The stupa existed as a tome of holy leaders even before the birth of Buddha, which was called stupa or tupa in the Sanskrit and the Pali, the ancient language of India. The stupa was renamed accordingly in each Buddhism transmitted countries such as Ceylon, Tibet, Nepal, Myanmar, Thailand and China and also reshaped according to their own formative style. But its original meaning and type are kept unchanged. The stupa was established in the 4 holy places including the birth place of Buddha, the place where Buddha found enlightenment, the place where Buddha preached for the first time, and the place where Buddha died. Thus, a pagoda to commemorate holy ancient places is called Chaitya, which became differentiated from the stupa in which Sari is enshrined. The stupa means Nirvana, the eternal body of Buddha, and also a place filled with teaching and preaching of Buddhism. It signifies the symbol of Buddha who escaped from the death and rebirth, to achieve complete extinction, i.e. parinirvana, and to reach ultimate eternal world, rather than simply means death. During the non-statue of th Buddha period, people built the stupa to embody Nirvana of the Buddha, and worshipped the tomb where body of holy saints was enshrined. On the other hand, they also sanctified memorial things such as tools that holy saints used, the Bo tree under which one achieved Nirvana, Dharma cakra that implied words, footprint that carried out mission work, and a way to reach to heaven.

Barium ferrite particles were synthesized from Ba(NO$_3$)$_2$, Fe(NO$_3$)$_3$ and KOH mixed solutions using hydrothermal crystallization in supercritical water. The experimental apparatus for production of barium ferrite is a flow-type apparatus. Fine barium ferrite particles were produced because supercritical water causes the metal hydroxides to be rapidly dehydrated before significant growth takes place. The effects of Fe/Ba ratio and reaction time on the formation, particle size, and magnetic properties of barium ferrite were studied. When Fe/Ba ratio were varied from 0.5 to 12, single-phase barium ferrite powder was only produced in the range of 0.5〈Fe/Ba〈2. Also, with elevating reaction time, the BaO.6Fe$_2$O$_3$ particle size grew smaller. Especially, uniform barium hexaferrite particles of size 100-200nm were obtained at 80sec. In this study, therefore, single-phase barium ferrite particles are highly stable and can be produced continuously in a reaction time of less then 2min.

Three kinds of soybean curd were prepared with three coagulants such as calcium chloride, magnesium chloride and glucono delta lactone. The mineral contents of the three soybean curds were analyzed before soaking and after various lengths of soaking(1/2 hour, 1 hour, 2 hours, and 2 hours(water changed after 1/2 hour)). Results therefrom were as follows: 1. Before the three soybean cured were soaked, their moisture contents were 79-83g/%. The ash contents were 5.04g% in the soybean curd made with CaCl_{2}4.42g/% in the soybean curd prepared with MgCl_{2} and 3.86g/% in the soybean curd coagulated by glucono delta lactone. an analysis of calcium, magnesium and phosphorous contents showed that each element had a greater concentration in the soybean curds made with divalent mineral salts than in the soybean curd made with acid. 2. Changes taking place in the mineral contents of the soybean curds according to different soaking times were examined. The mineral contents tended to decease in process of soaking time. The soybean curds showed the highest rate of mineral dissolution after one hour of soaking, and then they tended to reabsorb minerals. When the soybean curds were soaked I freshly changed water for one hour and 30 minutes, their mineral contents indicated a greater diminishing trend but no significant difference was noticed among the different kinds of soybean curd. In case coagulant has been used excessively, it is necessary to soak the bean curds for about one hour to get the coagulant dissolved.

The Korean Legation in Washington, D.C., is a proof that Emperor Kojong of Chosun Dynasty tried to establish relationship with the U.S. in 1891, that was before the declaration to establish Korean Empire. In that sense, the building is a historic place. The legation building is a symbolic place attesting to the turbulent history at the time of 1890 to 1910, when Korea had to suffer the forced treaty with Japan in 1905 and the annexation into Japan, and then to the 20th century up to the present time, 2014. The legation building can be turned into a space to host well-planned exhibits to show Korea's history and culture to local residents, foreign visitors to Washington, D.C., and overseas Koreans. The followings are the basic principles for the future use of the legation in line with the basic direction. The building's use should not be limited to museum, but should be flexible to accommodate various different practical usage. It is necessary to make the Korean Legation building that can incorporate the characters and the history through modern interpretation of the historicity of the place, the Korean culture, and historical events. The future usage of the Korean Legation building should enhance the value as a cultural heritage by linking the interpretation of the historical events and real life shown through exhibits, performance and people.

The purpose of this study is to understand modernization process of korean housing during the past one century. To following up the changes of everyday lives of common peoples, magazines, news papers, tourist's records and gossip items were collected and interpreted from the microscopic point of view. In this study arguments on 'modernity' of korean housing was focused on some issues, thus, separation, differentiation, individualization, as well as privatization. Concrete discourses are; firstly, spatial isolation of housing and urban place each other, secondly, functional division of inner spaces of housing, and lastly, guarantee of privacy sphere. Historical changes of housing showed some meaningful phenomena. Before modernization housing was place of reproduction and consume at the same time. However after modern urban space came into existence and work and rest were separated, housing gained only mono function. Thus, housing have only one meaning as private place for nuclear family, that is "Home, Sweet Home." Instead of past multi-functional rooms, functional prescribed rooms, for example, dinning room, were newly born. In the past, the boundary between public and private sphere was not clear. For examples, everyday experiences of family were extended to the street and in the house in most cases spaces were shared. But after modernization the scale of individual spaces become larger and private life can be secured. Consequently, history of everyday life from traditional agricultural society to industrialized modern society demonstrates the structural context between the micro and macro dimension in the fields of human life. In other words, everyday lives and macro history response each other and create new perception of time-space structure in the modern housing.

Mobile IP는 단말기에 이동성을 부여해 줌으로써 이동중에도 network업무를 수행할 수 있게 해주었다. 하지만 Access Router간에 이동시 발생되는 handover의 시간으로 인하여 지연과 date loss의 문제점이 발생한다. 이를 해결하기 위하여 많은 연구가 진행되고 있다. IEEE802.21에거 표준화가 진행중이 MIH(media Independent Handover)는 이종망간 handover를 지원하기 위한 프로토콜이다. NIH는 주변 망의 Layer2 정보와 Layer3 정보 등의 네트워크 정보를 사전에 획득하도록 설계되어있다. MIH의 사전정보 획득기술을 활용하면 MN(Mobile Node)에서 handover 발생시 획득해야 하는 정보를 미리 얻을 수 있고 보다 효율적으로 망을 구성할 수 있다. 본 논문은 MIPv4에서 MIH를 활용하여 MN(Mobile Node)가 handover 할 것으로 예측될 때 MIH Table를 이용하여 Handover에 사용되는 정보를 미리 구축해 둔다. 이로써 Handover가 예측될 때 L2Trigger가 가지는 Init time을 개선시키고, 나아가 짧아진 init time 으로 AR간에 보다 협소한 overlap Length를 가지고 handover를 행할 수 있음을 확인할 수 있었다.

The purpose of our study is to clarify about the influence that the visual information gives to the brain activities when pressure exerted the abdomen by waist belts. The visual information means that the some different visual information is inputted it, and the brain activity is evaluated by Electroencephalogram(EEG) measurements. At the same time, we carried out the sensory tests and verified about the relations between the psychological stress and the brain activities. There was a difference in change in the power of the $alpha$ wave with the eyes opened between man and woman. from the result of the sensory test, in the case of under the condition in the darkness with the eyes opened, there was no change in the a wave with before the pressure and after the pressure. In the other cases, $alpha$ wave changed in the same way with before the pressure and after the pressure. In the case of the visible and the invisible in pressure place, $alpha$ wave changed in the same way with before the pressure and after the pressure, but there was a difference in value. From the above, it isn't recognized that the visual information is influencing a pressure sense but some influences are given to it to the brain activities.
