In this paper, we study smart healthcare devices that enable active health care by building health care system with acquaintances or family members rather than single health care. The company develops health care services for families regardless of age and gender through intuitive UI design as a target for young users who serve elderly parents. Automated collection of health information and real-time feedback are available, and data can be aggregated and analyzed through repeaters. It can also utilize structured databases in the form of big data. The services offered can be used to prevent diseases and reduce medical expenses through health care, while automatic management can maximize users' convenience and increase demand. By reducing the development period of products that are based on this technology, reducing the development period of products and strengthening competitiveness, the company has the advantage of inducing generation-to-generation communication in an era when it is becoming a nuclear family.

This study was carried out from April 11 to May 10 1990, in order to evaluate the effect of health education by school nurses on the regular schedule of 6 hours per week from 1987, and to compare with the result of the same study performed in 1987. The data were collected by questionnaire from 589 primary school students, 425 middle school students, and 888 high school students, total 1,902 students, and 208 primary school teachers, 169 middle school teachers, and 539 high school teachers, total 916 teachers in Seoul. Analysis of data was done utilizing SPSS-X program for percentage, frequency and Chi-square test. The major results obtained from this study were as follows: 1. The demand of health education was higher in high school students(p<0.01), but not in other students and teachers than in 1987(p>0.01). 2. The satisfaction to health education was higher in middle school and high school students, and high school teachers(p<0.01), but not in other students and teachers than in 1987(p>0.01). 3. The concern about school health events was higher in primary school and high school students than in 1987(p<0.01), but not in middle school students and every school teachers than in 1987(p>0.01). 4. The practice of knowledge obtained from health education was more in every school students than in 1987(p<0.01). 5. The delivery of knowledge obtained from health education to family was higher in primary school students, but lower in high school students than in 1987(p<0.01). 6. The concern about school nursing room was higher in primary school students(p<0.01), but not in other students(p>0.01). 7. The interest pattern of students about health was revealed to be changed compared with the data obtained in 1987 : the most interested part was family health and sex.

The current world wide interest in environmental issues has moved from energy conservation to $CO_2$emission reduction. Recently, according to the increase in demand for water resources, insufficient potable water circumstance is supposed, unless there are corresponding in crease in water conservation and water recycling. This study has attempted to analyze $CO_2$emission reduction by water saving strategies like installation water saving devices, rain water harvesting and grey water system. To do this, this research investigates applicable water conservative strategies by literature review and calculated total water saving. The results show that (1) firstly, the water usage and $CO_2$ emission could be reduced up to 44%, (2) $CO_2$ emission reduction by water saving devices and rainwater harvesting system is about 47.7%, and (3) water usage and $CO_2$ emission reduction by grey water system is about 66%. In the future, this paper will be utilized for water management from the early design stage to maintenance stage of water glutton building.

Some Korean men choose to marry a foreigner expecting that marriage will solve all their problems. Therefore, this case study is to provide basic information on how to prevent conflicts in the marriage and how to get used to the marriage life. first, it is apparent that these match-makings between Korean men and married Female Immigrants are commercialized and are based on the two parties' convenience. Second, it is more possible that the issues with the role of husband/wife and the allocation of household labor stem from the cultural differences from international racial differences rather than Korean men are authoritative or patriarchal. It seems that the foreign brides from the third world countries choose to many Korean men with only a single purpose to financially help their parents. While neither willing to share household labor nor providing what is expected to be a wife, they demand financial assists for their parents or choose to get a job at a factory to make money. Third, the husbands expect their wives to learn Korean since there is not much opportunity to learn the wives' language and the culture. Also, the textbooks are rare to find for the languages. Moreover, the husbands do not have the enthusiasm or the ability to team due to age Fourth, the Korean men are rather psychological, financial, social victims than domestic abusers.

The purpose of this study was to construct a substantive theory about the substantials of stress of Korean Wives in the community. The subjects were 10 wives. In the process of data analysis, 'burden' was found to be the core phenomenon. And the properties of burden were 'burden of domestic economy', 'a sence of duty about the esteemed family of her husband', 'role burden in a family and her work place', and 'burden of conception'. Twenty five hypotheses were derived from the integration of categories. It is as follows : 1. The stronger the difference as perceiced by subjects, the stronger the burden will be. 2. The stronger the dissatisfaction, the stronger the burden will be. 3. The stronger the trouble, the stronger the burden will be.4. The stronger the worry, the stronger the burden will be. 5. The stronger the forcible demand, the stronger the burden will be. 6. The stronger the regret, the stronger the burden will be. 7. The rarer the communication, the stronger the burden will be. 8. The stronger the fatigue, the stronger the burden will be. 9. The stronger the anger, the stronger the burden will be. 10. The stronger the worrisome feeling, the stronger the burden will be. 11. The stronger the unbearable feeling, the stronger the burden will be. 12. The stronger the resentment. the stronger the burden will be. 13. The stronger the sence of insufficiency, the stronger the burden will be. 14. The stronger the estrangement, the stronger the burden will be. 15. The stronger the attachment, the stronger the burden will be.

With increased social participation of married women and with the notion of importance of pre-school childhood on human development, the importance of nurseries is being emphasized. The transformation of the traditional family system into a nuclear family system and the deterioration of the traditional child education have also put nurseries as a primal social interest. But, at present, at the end of 1994, only 10% of the children have benefitted from such facilities, the supply not being able to meet demand. Also, the spatial organization and the management of such facilities has been unsatisfactory. In this perspective, this study aims to grasp the present condition of nurseries, to investigate and analyse case studies, to suggest standards and reform measures, and based on these, to produce basic information for the formation of an architectural spatial model. We've selected investigation of present conditions and case studies, interviews, and observation as investigative methods and through these we've assessed tangible spatial planning and spatial proportion by parts. 1. The most preferred grouping method is toddler/preschooler type, and the group size and staff-to-child ratios vary according to the children's age 2. The younger children's activity rooms are located in the lower level, and the activity room of the children on the similar development stages are located adjacent to one another 3. Most of the facilities do not have the public spaces(indoor playrooms, dinning rooms, napping rooms, bathrooms, sickrooms) For dinning and napping, activity rooms are being used, and for sickrooms, director's room or staff rooms 4. As for the correlations of the spaces(home bases, activity rooms and its outdoor spaces, day-care-centers and its community), closed plan type is 90% over, and modified open plan is 10% min.

Saussurea costus (Falc.) Lipchitz syn S. lappa C. B. Clarke (commonly known as 'Kuth') belonging to the family Asteraceae is a well known medicinal plant which finds wide usage in different indigenous systems of medicine of India, China, Korea & Tibet. In different folk medicines the roots of S. costus are used to treat various disorders like ulcer, stomachache, malaria, leprosy, dysentery and toothache. However due to over exploitation, it has become endangered and has become the concern of different governmental bodies in India. The increasing demand of this endangered Himalayan species has resulted in a situation where it is often substituted, knowingly or unknowingly, by other morphologically similar species. Arctium lappa, belonging to the same family, is one such plant that has often been found to be present in the market samples of 'Kuth'. The present study was thus carried out and morphoanatomical characters, physicochemical as well as chemical parameters were developed for proper identification of roots of S. costus and its differenciation from A. lappa as well as authentication of the commercial market samples. The detailed morphoanatomical studies revealed that roots of S. costus can be distinguished from A. lappa on the basis of some important microscopial characters eg. the schizogenous resin ducts observed in roots of S. costus, were absent in A. lappa.. Besides, the HPTLC fingerprint profile showed a distinct band at Rf. 0.72 in S. costus, which was totally absent in A. lappa and a band at $R_f$ 0.64 in A. lappa which was absent in S. costus Chlorogenic acid, used as a chemical marker for HPTLC analysis, was estimated to be 0.077% in S. costus as compared to 0.107% in A. lappa. Thus these detailed pharmacognostical parameters can be successfully used to distinguish between roots of S. costus and A. lappa.

The proliferation of the Internet of Things (IoT) technologies and applications, especially the rapid rise in the use of mobile devices, from individuals to organizations, has led to the fundamental role of secure wireless networks in all aspects of services that presented with many opportunities and challenges. To ensure the CIA (confidentiality, integrity and accessibility) security model of the networks security and high efficiency of performance results in various resource-constrained applications and environments of the IoT platform, DDO-(data-driven operation) based constructions have been introduced as a primitive design that meet the demand of high speed encryption systems. Among of them, the TMN-family ciphers which were proposed by Tuan P.M., Do Thi B., etc., in 2016, are entirely suitable approaches for various communication applications of wireless mobile networks (WMNs) and advanced wireless sensor networks (WSNs) with high flexibility, applicability and mobility shown in two different algorithm selections, TMN64 and TMN128. The two ciphers provide strong security against known cryptanalysis, such as linear attacks and differential attacks. In this study, we demonstrate new probability results on the security of the two TMN construction versions - TMN64 and TMN128, by proposing efficient related-key recovery attacks. The high probability characteristics (DCs) are constructed under the related-key differential properties on a full number of function rounds of TMN64 and TMN128, as 10-rounds and 12-rounds, respectively. Hence, the amplified boomerang attacks can be applied to break these two ciphers with appropriate complexity of data and time consumptions. The work is expected to be extended and improved with the latest BCT technique for better cryptanalytic results in further research.

End-uses of household water have been changed by a life style, housing type, weather, water rate and water supply facilities etc. and those variables can be considered as an internal and exogenous factors to estimate long-term demand forecasts. Analysis of influential factors on water consumption in households would give an explanation to cause on the change of trend and would help predicting the water demand of end-use in household. The purpose of this study is to analyze the demand trends and patterns of household water uses by metering and questionnaire such as occupation, revenue, numbers of family member, housing types, age, floor area and installation of water saving device, etc. The peak water uses were shown at Saturday among weekdays and July in a year based on the analysis results of water use pattern. A steep increase of total water volume can be found in the analysis of water demand trend according to temperature from $-14^{\circ}C$ to $0^{\circ}C$, while there are no significant variations in the phase of more than $0^{\circ}C$, with an almost stable demand. Washbowl water shows the highest and toilet water shows the lowest relation with temperature in correlation analysis results. In the results of ANOVA to find the significant difference in each unit water use by exogenous factors such as housing type, occupation, number of generation, residential area and income et al., difference was shown in bathtub water by housing type and shown in kitchen, toilet and miscellaneous water by numbers of resident. Especially, definite differences in components except washbowl and bathtub water, could be found by numbers of resident. Based on the result, average residents in a house should be carefully considered and the results can be applied as reference information, in decision making process for predicting water demand and establishing water conservation policy. It is expected that these can be used as design factors in planning stage for water and wastewater facilities.
