Preconstruction process in a lean project delivery system was studied in one large healthcare project working for a general contractor. Researchers joined a new lean delivery project for approximately six weeks and participated in preconstruction process including design coordination, management coordination, and target costing while concurrently interviewing other project participants and employees, recording activity in meetings, and otherwise observing the process. The preconstruction process in lean project delivery system, called integrated project design, showed many benefits such as brining expertise of downstream players (i.e., mechanical and electrical contractors) into the design phase. However, lack of leadership and lack of design-integrator blocked the successful application of a new concept of design process.

The study on social robots has been actively conducted in the robot research community. In the area of robot design, however, there are few studies regarding robot motions that are one of the methods for interaction between humans and robots. This is a preliminary study to find preferred human motions that can be applied to social robots. We conducted a two-phased empirical study about preferred human motions. In the first phase, four representative human motions, such as 'greeting', 'I don't know', 'positive answer', and 'giving', were captured through 28 body makers and video recording. 10 young and 6 elderly Singaporeans participated in the motion capture process. In the second phase, the communication efficiency, emotion, and satisfaction of the human motions recorded in the first phase were measured by a questionnaire and 31 young Koreans, 35 young Singaporeans participated to investigate cultural differences. We drew the conclusion that motions used in the same culture are efficient in communication and also give friendliness and satisfaction. In addition, regardless of user's culture, young people's motions and female motions were preferred in terms of communication efficiency, emotional aspect, satisfaction.

Purpose: The purpose of this study was to determine the effects of music therapy on postpartum blues and maternal attachment of puerperal women. Methods: The research design was a nonequivalent control group non-synchronized design. The participants were puerperal women who agreed to participate in this study and through a convenience sampling, 60 puerperal women were recruited (30 in the experimental group, 30 in the control group). After measuring postpartum blues and maternal attachment, music therapy was provided to the experimental group over 40 min, once a day, and for 8 days. Then, postpartum blues and maternal attachment for the experimental and control group were measured again on the 8th day. The data were analyzed using the SPSS WIN 12.0 Program. Results: The first hypothesis that "the degree of postpartum blues for the experimental group who participated in music therapy would be lower than that of the control group" was accepted (t=4.350, p<.001). The second hypothesis that "the degree of maternal attachment of the experimental group who participated in music therapy would be higher than that of the control group" was accepted (t=4.828, p<.001). Conclusion: These findings indicate that music therapy has positive influences on decreasing postpartum blues and increasing maternal attachment of puerperal women.

Purpose: This study was done to develop a strength based I-change smoking cessation program for middle school boys and identified its effects. Methods: The study design was a nonequivalent control group pre-post test design. The participants were 97 middle school students from D city, who were in school from April 6 to September 25, 2015. The experimental group participated in the strength based I-change smoking cessation program, while the comparative group participated in a general smoking cessation program. The control group did not participate in any program. Data analyses involved $x^2$-test, Fishers' exact test, Bonferroni test, and Repeated measures ANOVA, with the IBM SPSS for Windows (version 20.0) program. Results: Compared to the comparison and control groups, the experimental group showed significant improvement in knowledge, attitude, self-efficacy, behavior change. Also cotinine in urine and modeling of social influence in the experimental group significantly decreased after the strength based I-change smoking cessation program. Conclusion: These findings indicate that the strength based I-change smoking cessation program is an effective intervention for middle school boys who smoke. The findings suggest that such programs can be used at public health centers or through school health education to decrease smoking in adolescents.

Purpose: The purpose of this study was to develop a family-participated cardiac rehabilitation program and to test the effects of the program on self-efficacy, health behavior compliance, and family support for patients with percutaneous coronary intervention. Methods: The design of this study was a nonequivalent control group non-synchronize design. There were 30 participants in the experimental group and 29 in the control group. The program consisted of six consecutive cardiac rehabilitation education and counselling sessions for 5 weeks. Data were analyzed using $x^2-test$, Fisher's exact test, and t-test using the SPSS program. Results: Self-efficacy, health behavior compliance, and family support scores were significantly increased in the experimental group compared to those in the control group. Conclusion: These results suggest that this program may improve self-efficacy, health behavior compliance, and family support in patients with percutaneous coronary intervention. Therefore, this program in which family members were included in supporting patients' adherence to health behaviors is recommended for use in clinical fields for the cardiac rehabilitation.

Objective: The purpose of this study was to investigate the effect of neck stabilization exercise combined with vibroacoustic sound on patients with chronic neck pain and tension-type headache. Design: Two group pre test - post test design. Methods: 36 patients participated. Headache impact test-6(HIT-6), numerical rating scale(NRS) and muscle characteristics were measured at pre-post test. Participants divided into vibroacoustic sound group(VSG, n=18), control group(CG, n=18). VSG performed neck stabilization exercise and vibroacoustic sound stimulation. CG performed neck stabilization exercise. Both groups participated 3 times a week for a total of 4 weeks. Results: NRS showed a significant difference before and after intervention in both groups (p<0.05). HIT-6 showed a significant difference before and after intervention in the VSG group (p<0.05). Muscle tone showed a significant difference before and after intervention in the experimental group (p<0.05). There was no significant difference in muscle stiffness and muscle elasticity before and after the intervention in both groups (p>0.05). Conclusions: Based on the results of the study, it is thought that sonic vibroacoustic sound can be established as an effective treatment tool through a study applied to various diseases and symptoms.

The role of social networking mobile applications such as WhatsApp in enhancing second language vocabulary learning among English language learners continues to be a subject of interest for many scholars. The current study aimed at examining medical English vocabulary learning among undergraduate students using WhatsApp compared to learning vocabulary via the Blackboard platform during the Covid-19 pandemic. To this end, 108 medical students (51 males, 57 females) enrolled in a first semester English for a specific English course participated in the study. A quasi-experimental design was adopted for two groups. Fifty-three students participated in the WhatsApp group and 55 students formed the Blackboard group. A pretest-posttest design was employed to collect data. Results of t-test scores did not show a significant difference between the WhatsApp and Blackboard groups on a vocabulary test. Results of a survey that measured students' opinion of the use of WhatsApp as a platform for learning new vocabulary showed positive perceptions since participants thought that WhatsApp enhanced their learning experience.

This study focuses on visual aesthetic factors in the apparel web site design. 103 undergraduates participated in the evaluation of six internet web sites. The evaluation were recorded and analyzed by using the inspection method and a questionnaire. Findings of this study can be summarized as follows: First, the result of SPSS-factor analysis shows that there are 2 distinct factors; 'classical aesthetics' and 'expressive aesthetics'. 'classical aesthetics' and 'expressive aesthetics' can be described by visual aesthetic design. This conceptual confusion relating to 'visual aesthetic design' can be clarified by these findings. Second, as a result of multiple regression analyses, 'classical aesthetics' and 'expressive aesthetics' have a positive influence on 'interactivity' and 'web site evaluation'. This research clarifies the concepts of 'engagement' of Rosen & Purinton as the 'interactivity' between users and web sites. Finally, this study suggests that 'good design' for internet web sites depends on understanding how to attain the appropriate balance between 'classical aesthetics' and 'expressive aesthetics', based on the target customer.
