This study investigated the effect of career education using female scientists role models on science-related attitude, science career awareness, gender stereotype of science-related career, and image of scientists. Interaction effect with students' gender were also investigated. The subjects of this study were 70 $5^{th}$ grader. The experimental group was introduced career education using female scientists role models with 7 cases of female scientists in the form of 10 minutes movies or cartoons, while the comparison group performed reading science books. The results showed that science-related attitudes and science career awareness of experimental group were significantly higher than control group, not only for girls but has for boys. Gender stereotype of science-related career has changed more neutrally in experimental group. After the career education using female scientists role models, more female scientists were presented in students' image of scientist in DAST. This results showed positive effects of the career education using female scientists role models and educational implications were discussed.

Purpose - Drawing upon signaling and social identity theories, this study explores the effect of engagement in CSR activities by foreign firms on applicants' intention to apply. Furthermore, this study suggests CSR education as a moderator which strengthens the positive effects of the engagement in CSR activities on the intention to apply for potential job seekers. Research design, data, and methodology - One hundred and ninety-one undergraduate students were solicited to participate in this study. Participants were randomly assigned to two scenarios depicting different levels of a given foreign firm's engagement in CSR activities. After reading the given scenario, respondents answered a series of questions on their intention to apply to the foreign organization. Result - The results from hierarchical regression reveal that Korean applicants have a more favorable perception of a foreign firm which performs engagement in positive CSR activities. Moreover, the positive effect of the engagement in CSR activities on the intention to apply has a greater impact for Korean applicants who had CSR education. Conclusion - The result indicates that foreign firms could overcome the liabilities of foreignness and attract local talent effectively, by engaging in CSR activities. Moreover, this study suggests the important role of CSR education, and significantly contributes to the international recruiting literature.

Many organizations facilitate a host of online knowledge sharing communities to assist internal knowledge sharing and operation. The permeable boundaries and voluntary structures of online communities allow individuals to span community boundaries and affect member resources and structures. Although much research has been done on members' knowledge contribution in online communities, relatively little is known about how a member's contribution to a community is shaped by the cross-level interactions of member's external boundary spanning and the community's environmental scanning or membership fluidity. Drawing from the theoretical lens of boundary spanning and the external view of online communities, we take a multi-level approach in the analysis of the activities of 1,992 members of 126 communities internal to a global company. We find that a member's external boundary spanning activity (e.g., external knowledge acquisition via reading posts) has a positive effect, though at a decreasing rate, on subsequent internal knowledge contribution (e.g., posting replies in the member's home community). This positive effect is stronger in communities that are more active in environmental scanning or have fluid membership and weaker in communities that are less active in environmental scanning or have stable membership.

Stroke is one of the most common disabilities experienced by the elderly in the community. However, stroke progresses to a chronic level, patients are discharged from medical institutions and eventually no longer receive therapeutic interventions at home. In this systematic review, we compared home-based rehabilitation (HBR) with comparison for patients with stroke. Literature published in Cumulative Index for Nursing and Allied Health Literature (CINAHL), Embase, Physiotherapy Evidence Database (PEDro), PubMed, and Google Scholar were reviewed. A total of 1,158 studies were initially retrieved. After reading the full texts, 11 articles were included in the systematic review. Quality assessment of the included studies was conducted using Risk of Bias (RoB) 2.0, and Egger's regression test was used to evaluate publication bias. Data analysis was performed using the R studio software (R Studio). According to the quality assessment using RoB 2.0, three studies were evaluated as low risk, two as of some concern, and three as high risk. The overall effect size was moderate (0.309). The value of the balance function was a small effect size (0.201), while the value of the gait function was a moderate effect size (0.353). The values were small and moderate effect (0.154, 0.411) for the chronic and subacute conditions, respectively. According to the Egger's regression test, no publication bias was observed. The findings of this study indicate that HBR resulted in the greatest improvement in gait function in patients with subacute stroke compared to those with chronic stroke. Therefore, the application of this intervention to patients with stroke in the community is recommended.

Giant magnetoresistance(GMR) NiO multilayer, which has been used to reading head of highly dense magnetic recording, was fabricated, and oxidized in an air during 80 days to study the dependence of magnetoresistance properties on residual stress in the interfaces. The magnetoresistance ratio and the exchange biasing $field(H_{ex})$ of $NiO(60nm)/Ni_{81}Fe_{19}(5nm)/Co(0.7nm)/Cu(2nm)/Co(0.7nm)/Ni_{81}Fe_{19}(7nm)$ spin valves were increased from 4.9% to 7.3%, and 110 Oe to 170 Oe after natural oxidation in the atmosphere for 80 days, respectively. The sheet resistivity ${\rho}$ decreased from $28{\mu}{\Omega}m$ to $17{\mu}{\Omega}m$, but ${\Delta}p$ did not almost change after the oxidation. Therefore, the increase of MR ratio is due to the decrease in the sheet resistivity. the reduced resistance may result from the increase in the reflection of conduction electrons at the oxidized top surface. Also, the increase in the exchange biasing field is originated from the reduction of residual stress at the interface of $NiO/Ni_{81}Fe_{19}$ according as the aging time increases.

The present study analyed jitter and shimmer of the deaf in 4 different voicing conditions. Thirty-two male subjects and 27 female subjects participated in the study on a voluntary basis. The age ranged from 6 to 18 for male and 8 to 21 for female subjects. The subjects were either congenitally or prelingually deaf The four different voicing conditions included /a/ prolongation, counting, reading, and conversation. The experiment utilized CSL Visi-Pitch Model 6095(Kay Elemetrics Corp.) to sample and analyze the data. Both jitter and shimmer means were higher than the threshold values(normative data) reported. In addition, this investigation performed two separate 2-factor ANOVAs in order to determine if jitter and shimmer change as a function of gender and voicing condition. The results showed the following. First of all there was the gender effect on shimmer but not on jitter, in that male subjects 'shimmer was higher than females'. secondly, there was the voicing condition effect both on jitter and shimmer. /a/ prolongation and reading produced lower jitter than counting and conversation. /a/ prolongation produced lower shimmer than the remaining conditions. Finally, no interaction between gender and voicing condition existed.

The flow around a foil with water jet was investigated using the two-frame PIV(CACTUS 3.1) system. After separation, unsteady recirculation & reattachment region was shown a result at reading edge. Separation area was decreased to 1/3 more by waterjet system with coanda effect. Angle of attack and water jet velocity was a variable in the experiment. Each parameters was controlled to $0^{\circ}\sim35^{\circ}$ and $0[m/s]\sim9.2[m/s]$. The separation of flow appearanced at first when the angle of attack is $17^{\circ}\sim18^{\circ}$, However, according to grew up of velocity, beginning of the separation was delayed. In this experiment, vortex and separation region was disappeared by blown when each parameters are low level, and separation controlled more certainly.

The purpose of this study were to develop cooperative learning lesson plan for middle school home economics class and to identify the effect of cooperative learning on students\` self-esteem. The content of lesson was chosen from the food and nutrition section of home economics textbooks for middle school. The main structure of the lesson plan stems from $\boxDr$Lesson Plan Guide of Structuring Cooperative Learning Lesson Plan for Teachers$\boxUl$ by D. Johnson. R Johnson and E. Holubec. Various kinds of references including media reading materials cooperative group activity reports and cooperative group activity checking lists were newly developed according to the content of lesson. Eight hour lesson plans were developed and applied to 2nd grade middle school students and pre-test and post-test were taken to test the effect of Johnson\`s cooperative learning method on students\` self-esteem. Students at a Middle School located in Seoul were divided into two grouts, the three classes as experimental group and the other three classes as control group. The data were analyzed by ANCOVA using SPSS/WIN program. As a result, the hypothesis that the degree of self-esteem of the experimental group is higher than that of control group was adopted (P.(001). Among the sub-factors of self -esteem. the global self-esteem and the social-peer self-esteem scores of the experimental group were higher than that of the control group(p.(001 each). but the school-academic self-esteem score was not different (p> .05) According to the post-experiment free-style report. student as a dynamic subject could get initiatives and interests in home economics class more effectively by cooperative learning. Therefore, it could be said that cooperative learning has positive effect on the promotion of students\` self-esteem and is considered to be a good teaching method of home economics subject.
