This paper aims to design and implement a robot that will help teach children living habits and English conversation education in dual-income families using the open platform robot Q.bo one based on raspberry pi3 of a single board computer. The first function of life habit formation is to help children to wash their hands, to brush their teeth, homework and sleep regularly. The child is then photographed listening to the notification and acting so that the parent can identify and provide feedback. The second basic conversation education feature uses Google's DialogFlow to help children learn English naturally through simple English conversation through the robot. The two-functioning robot allows children from working families to feel secure by printing their parents' voices even when they are not at home. At the same time, it allows them to get into basic lifestyle, to have basic English conversation with robots, and to be interested in English early.

Recently, floating green algae (FGA) in open oceans and coastal waters have been reported over wide area, yet accurate detection of these using traditional ground based measurement and chemical analysis in the laboratory has been difficult or even impossible due to the lack of spatial resolution, coverage, and revisit frequency. In contrast, spectral reflectance measurement makes it possible to quickly assess the chlorophyll content in green algae. Our objectives are to investigate the spectral reflectance of the FGA observed in the Yellow Sea and to develop a new index to detect FGA from satellite imagery, namely floating green algae index (FGAI), which uses relatively simple reflectance ratio technique. The Moderate Resolution Imaging Spectroradiometer (MODIS) and Geostationary Ocean Color Imager (GOCI) satellite images at 500m spatial resolution were utilized to produce FGAI which is defined as the ratio between reflectance at 860nm and 660nm bands. Both FGAI results yielded reasonable green algae detection at the regional scale distribution. Especially houly GOCI observations can present more detaield information of FGAI than low-orbit satellite.

Purpose: The purpose of this study was to investigate the degree of performance of TB control manpower in Korea and to identify the affecting factors associated with it. Methods: This study employed a quantitative observational with cross-sectional design and the subjects were consisted of 189 TB (Tuberculosis) control manpower who were working in both community health centers and private hospitals. Variables included in this study were demographic, social, work-related characteristics, aqhnd self-efficacy. A reliability of the instrument for the performance was Cronbach's ${\alpha}$=.91. Data were analyzed by t-test, ANOVA and multiple regression using SPSS (19th version). Results: The mean value of the degree of work-related performance of TB control manpower was $4.4{\pm}0.49$9 and it was higher than those of general nurses working in any other health care departments. The mean differences in the degree of work-related performance were in self-efficacy, workplace, the number of full charge manpower in TB, the number of participation in in-depth education, and the willingness to job maintenance. In multiple regression analysis, factors associated with TB control manpower' work-related performance were self-efficacy (${\beta}$=.164, p=.025), workplace (${\beta}$=-.186, p=.023), the number of participation in in-depth education(${\beta}$=.339, p<.002), and the willingness to job maintenance (${\beta}$=-.157, p=.036). Conclusion: Results of this study showed that work-related performances of manpower working in private hospital were higher than those of manpower in public health centers. So, it is necessary to enhance nation's active intervention to improve effectiveness and reduction of risk factors in TB policy.

The main purpose of this study is to get insight into the essential cognitive basis of local food purchase behavior based on Ajzen's (1991) theory of planned behavior. By asking open-ended questions using an online survey, participants' (n=163) salient behavioral, normative, and control beliefs in regard to local food purchase were assessed and analyzed. The most salient advantage was supporting local economy, followed by freshness, knowledge of where the food came from and how it was handled, environmental benefits, and health benefits. Assessing to consumers' normative beliefs found that local businesses, local farmers, family, local people, and friends were the most frequently mentioned individuals or groups who would approve consumers' local food purchasing. In contrast, the most salient barrier was inconvenient store location and time, followed by higher prices, limited availability and variety, and limited knowledge about where to buy local food.

Objectives: This study examined how ethanolamines (EAs) with the same functional alcohol group ($HOCH_2CH_2$), such as mono-EA (MEA), di-EA (DEA), and tri-EA (TEA), in water-based metalworking fluids (wbMWFs) are vaporized, condensed, and transformed by heat generated during metalworking. Methods: Two types of experimental apparatus were manufactured to achieve these objectives. Results: Vaporization tests using a water bath showed that the vaporization rate increased markedly from $0.19\;mg/m^2{\cdot}min$ at $23.5^{\circ}C$ to $8.04\;mg/m^2{\cdot}min$ at $60^{\circ}C$. Chamber tests with a heat bulb revealed that "spiked" MEA was fully recovered, while only 13.32% of DEA and no TEA were recovered. Interestingly, non-spiked types of EAs were detected, indicating that heat could convert EAs with more alcohol groups (TEA or DEA) into other EAs with fewer group(s) (DEA or MEA). The EA composition in fresh fluid was 4% DEA, 66% TEA, and 30% MEA, and in used fluids (n = 5) was 12.4% DEA, 68% TEA, and 23% MEA. Conversion from TEA into DEA may therefore contribute to the DEA increment. Airborne TEA was not detected in 13 samples taken from the central coolant system and near a conveyor belt where no machining work was performed. The DEA concentration was $0.45\;mg/m^3$ in the only two samples from those locations. In contrast, airborne MEA was found in all samples (n = 53) regardless of the operation type. Conclusion: MEAs easily evaporated even when MWFs were applied, cleaned, refilled, and when they were in fluid storage tanks without any metalworking being performed. The conversion of TEA to DEA and MEA was found in the machining operations.

It is not an easy matter to develop problems which help students understand mathematical concepts correctly and precisely. The aim of this paper is to review the merits and demerits of three problem types (i.e. one answer problems, multiple choice problems and proof problems) and to suggest some points that should be taken into consideration in problem making. First, we presented the merits and demerits of three types of problems by examining actual examples. Second, we discussed some examples of misleading problems and the ways to make desirable ones. Finally, on the basis of our examination and discussion, we suggested some points that should be kept in mind in problem making. The major suggestions are as follows; i) In making one answer problems, we should consider the possibility of sitting a solution by wrong precesses, ii) In formulating multiple choice tests which are layered for their easiness of grading, we should take into account the importance of checking whether the students are fully understanding the concepts, iii) We may depend on the previous research result that multiple choice tests for proof problems can be helpful for the students who have insufficient math background. Besides those suggestions, we made an overall proposal that we should endeavor to find ways to implement the demerits of each problem type and to develop instructive problems that can help students understanding of math.

This study has purpose to perform leaving the hospital nursing plan during hospital treatment of patient with the knee ligament Injury on the basis of the concerns between the time of leaving the hospital after 2 weeks in hospital and the concerns through practical life after leaving the hospital systematically. This study is also tried to make exercise plan to prevent atrophy of Quardriceps muscle of the thigh caused by the limitation of activities. The subjects of study are 12 people who were in the hospital in affiliation to a university in Seoul, were operated on the knee ligament, and were discharged from the hospital within 2 weeks. Data collection time was for about 4 months from December, 94 to March, 95. Research method was performed 2 times by unorganized open questions. The collection of first data is through direct interview about the concerns before leaving the hospital, and secondary data is through direct interview about the concerns by practical life and experiences after leaving the hospital. The data was categorized by classifying several common elements among similar contents according to data by the situational analysis of Giorgi. The result of this study is as follows : 1) The concerns before leaving the hospital are like that the concerns of recovery possibility, the limitation of activities, the grim realities of life, the lack of confidence about self-nursing, the eyes of the surroundings, the burden to the others, and so on. 2) The concerns after leaving the hospital are like that the demands of the inconvenience by the limitation of self-nursing, the support about self-nursing by the difficulties of performing treatment order, the support of physical activities limitation by physical tiredness and the limitation of social activities, the support of information by the necessities of education in using crutches before leaving the hospital and continuing informational needs, psychological and mental support of normal physical recovery by the worries of physical recovery and physical change, and social support by thankfulness for his family and relatives. I suggest to make more systematic leaving the hospital nursing plan and exercise education plan for nursing plan after leaving the hospital of the patients with the knee ligament injury on the basis of this content.

Background: Intersectoral and multidisciplinary collaboration is becoming more prominent in all facets of government, health, social services, and scientific endeavors. An interplay of a multitude of driving forces moves multiple disciplines forward to achieve quality outcomes in health and social sciences services and research. Aim: This paper aims at discussing the prospects for future multidisciplinary collaboration. If inter organizational integration and multidisciplinary collaboration are the ways of the future in academia and the scientific world, it then becomes crucial to examine what lies ahead for the nursing profession, Discussion: This paper argues that in order for multidisciplinary endeavors to succeed, the leaders in multidisciplinary teams shoulder the largest share of the responsibilities involved. In developing a lasting team constituting professionals from different disciplines, the leader needs to include the right individuals in the team, identify a common goal, build trusting relationships through open communication and interprofessional education, and empower members through creating room for autonomy and at the same time allowing space for personal development. The leader will need to utilize information technologies to manage communication issues in a large multi-site multidisciplinary project. Lastly, he or she must be able to demonstrate team productivity through process and outcome evaluation. It needs to be emphasized that it falls to each individual nurse to speak up and act upon what nursing believes and represents in our quest for success in multidisciplinary endeavors. Conclusion: The significance of the role of the leader is paramount for a team to succeed. Yet there is no prospect if only a handful of exceptional nurse leaders are moving ahead in multidisciplinary endeavors. Without the actualization of professional roles by each individual nurse, the profession will have no prospect in collaborations across disciplines.

The nucleotide sequence of the luxC gene coding for lux-specific fatty acyl-CoA reductase and the upstream DNA (325bp)of the structural gene from bioluminescent bacterium, Photobacterium phosphoreum, has been deternubed. An open reading frame extending for more than 20 codons in 325 bp DNA upstream of luxC was not present in both directions. The lux gene can be translated into a polypeptide of 54 kDa and the amino acid sequences of lux specific reductases of P. phosphoreum shares 80, 65, 58, and 62% identity with those of the Photobacterium leiognathi, Vibrio fischeri, Vibrio harveyi, and Xehnorhabdus luminescenens reductases, respectively. Analyses of codon usage, showing that a high frequency (2.3%) of the isoleucine codon, AUA, in the luxC gene compared to that found in Escherichia coli genes (0.2%) and its absence in the luxA and B genes, suggested that the AUA codon may play a modulator role in the expression of lux gene in E. coli. The structural genes (luxC, D, A, B, E) of the P. phosphoreum coding for luciferase (${\alpha}$,${\beta}$) and fatty acid reductase (r, s, t) polypeptides can be expressed exclusively in E. coli under the T7 phage RNA polymerase/promoter system and identificationof the [35S]methionine labelled polypeptide products. The degree of expression of lux genes in analyses of codon usage. High expression of the luxC gene could only be accomplished in a mutant E. coli 43R. Even in crude extracts, the acylated acyl-CoA reductase intermediate as well as acyl-CoA reductrase activities could be readily detected.
