The objective of this paper is to investigate the issues related to the supply chain management in plant engineering industry, and propose the framework to improve the project efficiency. The preliminary case study shows that EPC's fragmented nature, lack of coordination and information sharing, and lack of proper risk and change management contribute to project delay and cost overrun. To examine the level of informatization and information sharing in supply chain, survey responses from the suppliers and subcontractors have been collected. The statistical results show that information sharing, early involvement in design process and awareness in SCM have influenced the level of collaboration, but supplier assessment and informatization have no impact on the collaboration. A conceptual model is proposed in order to facilitate the integration of design, procurement and construction functions. Implications from the study are also provided.

Purpose: To develop Korean Menstrual Symptom Scale (KMSS) for university students and test its reliability and validity. Methods: The scale was developed by intensive literature review, development of preliminary items, verification of content validity, development of secondary items, verification of construct validity, and extraction of final items. Thirty-nine items were constructed. Data for validity and reliability testing were collected with a questionnaire survey from 391 university students. Data were analyzed with descriptive statistics, factor analysis, and reliability coefficients (Cronbach's ${\alpha}$) with the SPSS program. Results: There were 37 final items which were sorted into six factors: 'negative affection (8 items)', 'change of activity level (7 items)', 'physical symptom (9 items)', 'mood change (9 items)', 'change in concentration level (4 items)', and 'body water retention (5 items)'. The cumulative percent of variance was 63.3%. Regarding the reliability of the scale, its Cronbach's ${\alpha}$ was 0.96. Cronbach's ${\alpha}$ values for these factors ranged from 0.75 to 0.91. Conclusion: The KMSS demonstrated acceptable validity and reliability. Repeated research is needed to measure menstrual symptom experienced by women of variable ages.

Objectives Osteoarthritis is hard to manage with both conventional and Korean medicine treatment. The core outcome set (COS) to demonstrate the effectiveness of Korean medicine treatment has not been established yet. We aimed to present preliminary data of COS by performing a literature review on the evaluation indices used in existing clinical research. Methods We examined the literature from 2000 to 2017 in two Korean electronic databases (Korea citation index and oriental medicine advanced searching integrated system) by searching for the following 3 terms 'total knee replacement (Korean)', 'total knee replacement,' and 'knee surgery.' We found 333 articles; among them, 50 duplicates were removed. Finally, we selected 160 articles after complete screening. We then extracted measured indices and clinical outcomes from the selected articles and categorized the relevant criteria. Results According to this study, the hospital for special surgery and knee society, range of movement angle, cross leg, Berg balance scale and balance ability, muscle strength, 6 minutes walking test, visual analogue scale, self-efficacy, the 12-item and 36-item short form survey and self-rated health status are the most commonly used outcomes of knee. Conclusions This study found that the several categories after total knee replacement (TKR) are being evaluated in the literature, and we were able to verify the most frequently used evaluation indices in these categories. The results of this study will be used to establish evaluation indices for the treatment of TKR in the future using Korean medicine.

In Japan, apartment housing occupies a great proportion of residence due to high population density like Korea. Although Korea and Japan are similar in big proportions of apartment housing, and apartment housing management systems and utilization behaviors, there are considerable differences. This paper examined Japanese public facilities and the status of public facility management and utilization, which differ from those in Korea. In order to analyze the status of public facilities from a perspective of management companies, a preliminary survey was conducted targeting apartment management companies in the top 100 and a field study on public facilities was conducted targeting chief directors and managers of individual housing facilities to look into public facility utilization methods, problems with public facility management, demands of residents, and utilization situations. Also, the present state of facility utilization and utilization promotion plans were investigated, based on the drawings of facilities collected. As the result, results were found in three respects; 'elements, related to building plans', 'elements, related to utilization promotion', and 'elements, related to facility remodeling, including changes of uses'. In relation to the use of public facilities in the future, a more active communication between managers and users would be needed for planning. Also, there would be a need to provide public facilities for visitors when there are events for both occupants and visitors in order to promote the use of facilities and management companies would have to share information of excellent facility models.

Background: Lancet-related needlestick injuries (NSIs) occur steadily in clinical practices. Safety-engineered devices (SEDs) can systematically reduce NSIs. However, the use of SEDs is not active and no study to guide the implementation of SEDs was known in South Korea. The lancet-related NSIs may be eliminated to zero incidence using a SED lancet with effective sharp injury protection and reuse prevention features. Materials and Methods: We implemented a SED lancet by replacing a conventional prick lancet in a tertiary hospital in a sequential approach. A spot test of the new SED was conducted for 1 month to check the acceptability in practice and a questionnaire survey was obtained from the healthcare workers (HCWs). A pilot implementation of the SED lancet in 2 wards was made for 1 year. Based on these preliminary interventions, a hospital-wide full implementation of the SED lancet was launched. The incidence of NSIs and cost expenditure before and after the intervention were compared. Results: There were 29 cases of conventional prick lancet-related NSIs for 3 years before the full implementation of SED lancet. The proportion of prick lancet-related NSIs among yearly all kinds of NSIs during two years before the pilot study was average 11.7% (22/188). Pre-interventional baseline incidence of all kinds of NSIs was 7.01 per 100 HCW-years. After the full implementation of SED lancet, the lancet-related NSIs became zero in the 2nd year (P = 0.001). The average direct cost of 18,393 US dollars (USD) per year from device and post-exposure medical care before the intervention rose to 20,701 USD in the 2nd year of the intervention. The incremental cost-effectiveness ratio was 210 USD per injury avoided. Conclusion: The implementation of a SED lancet could eliminate the lancet-related NSIs to zero incidence. The cost increase incurred by the use of SED lancet was tolerable.

This study used a preliminary survey to help develop an ergonomic flight jacket that is suitable for the working environment and mission performance. The results are as follows. The ergonomic sleeve pattern was designed with a forward 165° incline that considers a shoulder joint direction suitable for the motion; in addition, a closely design opening provided warmth and safety from fire. As a result of the dimensional suitability, pilots evaluated that sleeve length and total length of the developed flight jacket were a little long (p<.01), while flight engineers and crew evaluated that those of the developed flight jacket were appropriate (p<.01). Pilots evaluated that chest circumference and waist circumference were large (p<.05), while flight engineers and crews evaluated that those of the developed flight jacket were appropriate. The evaluation of the motion suitability indicated that pilots, flight engineers and crew found the developed flight jacket more comfortable than the current flight jacket (p<.05, p<.01, p<.001). The evaluation of the usability of pockets and penholders indicated that pilots, flight engineers and crew found the developed jacket easier to use (p<.01). The flight engineers and crew evaluated that the appearance of the developed flight jacket was better than the current flight jacket (p<.05). The results of this study show that the difference of environment and mission performance has a significant influence on evaluation; therefore, it is necessary to develop separate military uniforms that included a winter flight jacket to reflect the needs of each group.

Background and objectives: Human papillomavirus (HPV) is the most common sexually transmitted infection globally and is responsible for multiple clinical outcomes, including genital warts and cervical, anal, and oropharyngeal cancers. Despite the well established burden of HPV on both men and women, vaccine uptake among men is critically low in Korea. A preliminary step to combat this issue is to target parents of male adolescents. In the present study, we aimed to assess any change observed in parents' HPV knowledge and attitudes towards male HPV and subsequent willingness to vaccinate their sons following an HPV educational intervention. Methods: On November 14, 2020, a one-time HPV educational session was conducted and parents (n=136) completed self-administered pre-/post-test questionnaires that included previously validated survey items. Paired t-tests were used to evaluate change in HPV-related knowledge, attitudes and intent for HPV vaccination. Results: Following the intervention, participants reported increased scores in HPV and vaccine related knowledge by approximately 4 and 1.5 points, respectively (p<.001). Parents scored higher on perceived benefits of the vaccine, perceived social influence on vaccination decision and perceived severity of diseases caused by HPV infections, whereas lower scores were observed for perceived harm of the vaccine, and difficulties communicating with their sons about sex and HPV vaccination. Following the intervention, those without the intent to vaccinate their sons significantly decreased and those who intended to vaccinate their sons though not in the next six months significantly increased (χ2=33.045, p<.001) Conclusion: Our educational intervention resulted in an increase in HPV-related knowledge with a positive impact on parents' attitudes toward male HPV vaccination. We expect that this study can serve as a pivotal reference to promote the unexplored issue of HPV vaccination among male adolescents in Korea.

This study is to understand the preferences of pilots, flight engineers and crew who work in the same aircraft but are exposed to different working environments and perform different mission operations in order to develop an ergonomic flight jacket. Based on a preliminary investigation, a survey of 107 pilots and 36 flight engineers and crew was conducted. The results are as follows; Pilots can control the temperature inside the cockpit, so they are less exposed to the cold when working, while flight engineers and crew are exposed to the cold more because they have many external tasks. The reason for the problem of the current flight jacket was a difference in ranking between two groups, but the highest ranking was poor dimensional suitability due to the habit of wearing layers of clothing. As a result of preferred design, there were significant differences between groups in the item of overall style. Pilots preferred a bomber jacket style(P:68.2%, E&C:44.4%), on the other hand, flight engineers and crew preferred a field jacket style(P:26.2%, E&C:55.6%)(p<.01). They preferred a stand collar(P:71.0%, E&C:86.1%), a fastener slider for a front fastening(P:62.6%, E&C:61.1%), fastener tape cuffs(P:54.2%, E&C:47.2%), a jacket with a softshell(P:86.9%, E&C:83.3%), fleece as softshell material(P:88.8%, E&C:69.4%), and fastener sliders as a attaching method(P:69.2%, E&C:61.1%). A hem fastening will be selected differently according to the overall style of outshell. Additionally, they preferred more than 5ea pockets(P:51.4%, E&C:44.4%), fastener sliders as pocket's fastenings(P:48.6%, E&C:61.1%), armpit ventilations(P:62.9%, E&C:58.5%). The results of above will be considered to design an ergonomic flight jacket.
