At most of the home or office, we have planted ornamental plants raised in pots, but it is difficult to follow because of busy life and lack of expertise in plants management. In this paper, we intend to design and implement a home network-based potted plants management system to solve the difficulty of plants management. To attain this end, firstly, we designed the structure of the plants management system, information flows and operation control flows. Secondly, we implemented the system based on designed results. Finally, we verified the implemented system through the functionality test for 10 items. In the results, it is expected that we can manage the potted plants efficiently than existing ornamental plant management systems and home network systems focusing appliances.

Korea is increasingly vulnerable to disasters due to changes in economic and social structure. In particular, there are a number of disadvantaged people, such as elderly people, disabled people, basic livelihood recipients, foreigners, multicultural families, etc. who are vulnerable to social problems due to aging, polarization and internationalization. These vulnerable people to disaster have difficulties in acquiring disaster information and to respond promptly by self-help. Of course, recent studies on vulnerable people to disaster have been steadily increasing, but discussions about foreigners have been relatively inadequate. This has led to a lack of understanding about the actual situation of disaster and coping methods. Once general situations set in, foreigners staying in Korea will suffer from a vicious cycle of policy-making from the viewpoint of Korean and difficulties in obtaining relevant information. In this study, we conducted in-depth interviews on the recognition and acquisition path of disaster information for foreign workers living in Korea. Based on the results of the interviews, we derived implications for practical information, such as ways to understand and actively utilize information media frequently visited by foreign workers in Korea.

This study examined the structural relationships among parent's play participation, children's playfulness, self-regulation and happiness. In this Study, subjects were 274 children who were 4 through 5 years old. The participants included 274 preschoolers' parents and their teachers in D city. The parents completed questionnaires regarding parent's play participation with their children and children's self-regulation. The teachers completed questionnaires regarding preschoolers' happiness and playfulness. Data was analyzed using descriptive statistics, pearson correlation analysis and mediation analysis based on structural equation modeling with SPSS 25.0 and AMOS 23.0 program. Also, specific indirect effects were analyzed using AMOS user-defined estimand function. The primary results of this study were as follows. 1) The parent's play participation had an influence upon children's playfulness and self-regulation. 2) The children's playfulness had an influence upon children's self-regulation and happiness. 3) The children's self-regulation had an influence upon children's happiness. 4) Between the parent's play participation and children's happiness were mediated by the children's playfulness and self-regulation. This study revealed that parent's play participation, children's playfulness and self-regulation need to be considered simultaneously to explain the level of the children's happiness. The results highlight the structural relationships among parent's play participation, children's playfulness, self-regulation and happiness.

국가 수자원 중 농업용수 사용비율은 약 41%에 해당하며, 통합물관리측면에서 큰 비중을 차지하고 있다. 국가 수자원 전체 이용량 372억m³ 중에서 농업용수가 40.9%인 152억m³로 가장 많고, 환경용수 121억m³(32.5%), 생활용수 76억m³(20.4%), 공업용수 23억m³(6.2%)등으로 추산된다. 국가 수자원관리의 중요성이 커짐에 따라 수량 및 수질관리를 환경부로 일원화하여 관리하며, 농업용수의 유역단위 물관리의 필요성이 요구되고 있다. 농업용수는 대부분 벼농사에 소비되고 있으며, 관개용수는 증발산량, 침투량, 자연 및 인위적인 배수량으로 소비된다. 회귀수량은 관개를 통해 농경지에 공급된 용수 중 작물에 의해 소모되지 않고 하천으로 유입되는 수량을 의미하며, 신속회귀수량(quick return flow)과 지연회귀수량(delayed return flow)으로 구분할 수 있다. 수자원장기종합계획에서는 35%가 하천으로 회귀되는 것으로 가정하고 있지만, 선행연구 결과에 의하면 국내 농업용수 회귀율은 기상상태, 작물재배품종, 재배형태, 용배수로 구조 등 여러 가지 요인으로 인하여 약 32 ~ 86%의 다양한 범위로 큰 차이가 나타난다. 이에 본 연구에서는 기존의 회귀수량 산정방법의 취약점을 보완하여, 수문모델링을 통한 유역단위 차원의 회귀수량 산정방안을 제시함으로써, 하천유지유량 관리 개선방안을 모색하고자 한다.

The purposes of this paper are to describe the newly established reference values of nutrient intakes: to apply the changed dietary reference intakes to the new text book based on the revised curriculum: and to contrive substantial contents in the domain of dietary life(foods & nutrition) of new text book. Dietary Reference Intakes for Koreans(KDRIs) is newly established reference values of nutrient intakes that are considered necessary to maintain the health of Koreans at the optimal state and to prevent chronic diseases and overnutrition. Unlike previously used Recommended Dietary Allowances for Koreas(KRDA), which presented a single reference value for intake of each nutrient, multiple values are set at levels for nutrients to reduce risk of chronic diseases and toxicity as well as prevention of nutrient deficiency. The new KDRIs include the Estimated Average Requirement(EAR), Recommended Intake(RI), Adequate Intake(AI), and Tolerable Upper Intake Level(UL). The EAR is the daily nutrient intake estimated to meet the requirement of the half of the apparently healthy individuals in a target group and thus is set at the median of the distribution of requirements. The RI is set at two standard deviations above the EAR. The AI is established for nutrients for which existing body of knowledge are inadequate to establish the EAR and RI. The UL is the highest level of daily nutrient intake which is not likely to cause adverse effects for the human health. Age and gender subgroups are established in consideration of physiological characteristics and developmental stages: infancy, toddler, childhood, adolescence, adulthood and old age. Pregnancy and lactation periods were considered separately and gender is divided after early childhood. Reference heights and weights are from the Korean Agency for Technology and Standards, Ministry of Commerce, Industry and Energy. The practical application of DRIs to the new books based on the revision in the 7th curriculum is to assess the dietary and nutrient intake as well as to plan a meal. It can be utilized to set an appropriate nutrient goal for the diet as usually eaten and to develop a plan that the individual will consume using a nutrient based food guidance system in the new books based on the revision in the 7th curriculum.

There is recent recognition that the approach toward family members is crucial for understanding problems in multi-cultural families by emerging from typical approach focused on migrant women. While researches have reported serious conflicts and adaptation problems from cultural difference between parent-in-law and foreign daughter-in-law, cultural stress of parent-in-law has not been systematically examined. The purpose of this study was to develop and validate a scale to measure acculturation stress of parent-in-law who have a foreign daughter-in-law. The sample consisted of 266 parents-in-law from three provinces of South Korea. Initially, 16 items were generated based on the existing scale of acculturation stress and they are tested by item-analysis through the descriptive and correlational analysis. An exploratory factor analysis was conducted to investigate the factor structure of the scale and a confirmatory factor analysis was used to validate the scale. By item-analysis, five items were deleted from initial scale items because of redundancy. Findings from an exploratory factor analysis provided the evidence that the scale consists of three factors which are the perception of prejudice and discrimination, conflicts from different cultural value, and daily discomfort. Cronbach's ${\alpha}$ for the scale is 0.86. Multiple fit indices from confirmatory factor analysis indicated that the hypothesized three-factor model for acculturation stress achieved a good fit with the data. Results showed the evidence for the reliability and validity of the scale for acculturation stress of the parent-in-law who have foreign daughter-in-law. The scale would have potential effects for assessing psychological stress for parent-in-law in research and clinical practice. Further implications and limitation of the study and suggestions for future studies were discussed.

The purpose of this study is to consider ontology theory and get to forge design and implementation of ontology-based access system which is support to the nutrition and food guide tower of Home Economics textbooks in middle school in order to offer the way of effective learning performance. It offers a model by establishing a nutrition and food guide tower access system based on Protege-2000 framework. This system is on the basis of XML, and it makes possible to work with semantic web, a next generation internet technology, and provides a meaning structure that can be shared in the field of nutrition in order to build up the fundament of knowledge an information system for the mutual operations. A learner can systemize the knowledge through a self-information access and an instructor can also check out the degree of learner's learning-accomplishment and interests, directly putting the access system into the teaching and learning process. In addition, it is supposed that the learner can maintain a balance and healthy life by internalizing his or her knowledge throughout ontology not only in a teaching and learning process but also in a daily life.

'gender' means sex in a social sense and 'sex'is more close to the concept of that discussed in biological light. 'Gender is more adequate word in expressing gender equality of both sexes than 'sex'that gives us discriminating impression and implies tout we should actualize equality between both sexes in all field of social activities. Though more and more women have been advanced into the job that was once regarded as a men only-area and the concrete list of iou for men and women has been changed in the process of job structure transition, women stiff take full charge of all kind of houseworks so they're still under the double torture of housework and their job. Most of the job in which men used to engaged in the past is now mechanized. and we can't deny that modern technology triggered women's participation in public affairs by helping them to lead comfortable family life without any assistant or trustee for housework. Under these trend of our times, we made an attempt to look into design mainly from the standpoint of women by raising the issue of correlation between women's labor in society and houseworks in the hope that current design and changes into one that can rejects women's position and allows them independent choice in the field involved with our real life.

The purpose of this study was to explore the differences in perceptions of male and female students about population problems and to draw up implications for population education. Using text mining, the report about population problem, which had written by students in population education class, were analysed. After extracting key words, semantic networks were visualized. The results were as follows. First, the high frequency words were the same for each gender. Second, key words based on frequency did not differ depending on gender. And the key words extracted by the correlation analysis and bigram were different. That is, in the semantic network of girls' words, the network of "life"-"marriage"-"birth"-"pregnancy" appeared independently, distinguishing it from male students who showed separate objective links to population problems. Therefore, it drew suggestions that male and female students should be viewed as heterogeneous groups with different cognitive structures on population problems and that the content and methods of population education should be approached differently depending on gender.
