The number of students choosing science, technology, engineering, and mathematics (STEM) related careers are declining. Thus it became a worldwide challenge in the $21^{st}$ century. As public images of the engineers are unfavorable and inaccurate, misconceptions and stereotypes about engineers are prevailing. The purpose of this study was to investigate elementary school students' perceived mental and pictorial images of engineers and the nature of engineering work. This study involved 512 fifth and sixth grade students (Boys: 287 and Girls: 225) from four elementary schools at one of metropolitans in South Korea. The Draw An Engineer-Korean version (DAE-K) was developed based on Draw an Engineer (DAE) and Draw a Scientist (DAS), and Song and Kim (1999)'s instruments. A pilot-tested was conducted with 33 elementary students prior to the main study. The students were asked to answer how they think the engineers would be, to draw an engineer at work, and to write the engineer's personal information and the job description. Engineers were perceived as a person fixing, building, manufacturing, working outdoors in labors' clothes such as a robe. Engineers were shown with building tools, robots, airplanes, machines, conveyor belt, etc. Moreover, compared to the scientists, engineers were perceived as less intelligent, less imaginative, and less accurate. The results of this study revealed that elementary school students had a lack of accurate images of engineers. Students' current perceived images of engineers could help educators find the baselines for the future engineering education in elementary schools. In addition, the findings of this study could also contribute to the development of engineering education in terms of gender issues, STEM career choice, and even cultural diversity.

Purpose - The purpose of this study was to propose a win-win development plan for not only suppliers of delivery applications but also traditional market vendor companies and delivery riders by analyzing existing delivery models and presenting a new delivery model to enhance competitiveness of the traditional market using delivery apps. Research desgin, data, and methodology - Specifically, small retailers, such as traditional markets and supermarkets, presented a compromised delivery model that utilizes the platform of specialized delivery app service providers for order reception, and that the delivery is delivered by delivery systems jointly hired by Vendor companies, such as franchising companies. To validate the significance of the trade-off delivery model, a cost-benefit analysis was conducted by those involved in the delivery application. Results - From the perspective of suppliers of specialized delivery applications, it is analyzed that the use of specialized delivery applications in traditional markets will be a new market opportunity for service providers to achieve increased sales. It is expected that consumer choice and satisfaction will be increased as convenience and accessibility of traditional market businesses that were available only through direct visit from the user side of the delivery application will be expanded. From the standpoint of delivery application franchises, it is analyzed that they can seek to increase sales and increase customer service as well as ease labor cost burden due to joint employment of delivery riders. The delivery rider will be able to seek to improve customer service due to job security, wage stability, risk reduction and overheated competition due to direct employment. Conclusion - In conclusion, the compromised delivery model solved the problems raised in the preceding study conducted on delivery application suppliers, users, franchises, and riders to establish that it could be a strategic alternative to increasing sales and expanding detailed rights for the self-employed in the traditional market, which are experiencing difficulties in management. However, the adoption of a compromise delivery model requires social consensus from those involved in the delivery application and requires legal, institutional and policy support, which will require continued follow-up research on the delivery model in the future.

The purpose of this research was to analyze the clothing behavioral attributes of male music enthusiasts. A questionnaire was developed based on previous researches. Respondents were men who were concerned with music in terms of a job, a major or a hobby. A total of 200 responses were analyzed by SPSS 20.0 through factor analysis with Varimax rotation, ANOVA with post-hoc test(SNK-test) and ${\chi}^2$-test. Music preference was classified into 3 factors: New age/jazz, Hiphop/dance, and Metal rock/ballad factor. 5 Clothing purchasing orientation factors were extruded: hedonic, planned, convenience, brand pursued, and fashion pursued purchasing orientation. Using those factor scores, 3 groups were classified: Group1(G1), preferring Hiphop/dance music with lower hedonic and brand/fashion pursued purchasing orientation; G2, preferring Hiphop/dance music with no interest in clothing shopping and fashion; G3, preferring New age music with high convenience and brand pursued purchasing orientation. In addition, there were significant differences among groups in clothing behavior such as social ostentation, individuality, self-expression, fashionability, conformity; in purchase motivation such as hedonic and trend/designer oriented purchase motivation; in information source like advertisement/media source; and in store choice criteria such as store light/music and popularity. The findings showed even the enthusiasts for the same music showed the different sopping orientation and different clothing behavior, suggesting that a personal value or taste can be a plausible factor to figure out attributes of consumers. An interest/involvement in clothing could be helpful to subdivide the music enthusiasts as the target market.

This study has sought to analyze factors affecting work and work preference of older adults at national and individual level. A few theoretical hypotheses such as economic need versus job opportunity (or employability), attitude toward paid work, pull effect versus push effect were tested for citizens in eighteen OECD countries with International Social Survey dataset(2005) using multi-level analysis. Main findings are as follows. First, most older adults wanted to work regardless of the socio-economic status, which implies that non-work of older adults would be due to involuntary constraint rather than voluntary choice. Second, there existed class inequality in that the higher class tended to involve paid work more than the lower class did among 55-64 age group. Third, the push factor such as part-time employment ratio, rather than the generosity of social security, explained the work and retirement patterns better. In conclusion, at least from the comparative perspective, the main problem of older adults' work seems to be of labour demand rather than of labour supply, to be of labour market structure and work opportunity rather than of the pull factor.

Natural ventilation technique could be the substitute for or the complement to the local exhaust ventilation system in the sense of protecting work environment. Moreover, it has many strong points ; almost no mechanical parts, no energy use and no noise. If applied appropriately, it could have the very high ventilation rate and save a lot of energy expense. But, it depends on the outdoor environment, especially temperature and wind speed/direction. Predicting the capacity of natural ventilation is not an easy job because it comes from both buoyancy and wind effect. Another problem is too much flow through the ventilator especially in winter time due to too much difference between indoor and outdoor temperature. Thus some ventilators in industries are sealed by door or plastic sheet, resulting in bad work environment. Various types of dampers are used to control the flow rate through ventilators. The capabilities of flow control by damper has not been estimated. In addition, it was not tested whether the damper could obstruct the flow through ventilator when fully opened. To answer these questions, 4 types of dampers were tested by using computational fluid dynamics. 10 different configurations includes no damper, full open and half open. Flow rates were estimated and airflow fields were analysed to clarify the before-mentioned questions. The dual type damper was the best choice for controling the capability of ventilator. In addition, the upward grill type damper was the best for not obstructing the air flow when fully opened.

We analyzed the characteristics of the physicians preferred information sources and barriers through in-depth interviews. Information searches for patient treatment were subdivided into deciding patient treatment methods, understanding the latest treatment trends, and preparing presentation materials for conferences. The variables that affected the search behaviors were identified as being background knowledge on the topic, clinical experience, job title, search skills, user training, and familiarity with the library homepage. PubMed was the most preferred choice because of users' familiarity, reliability, and the vastness of information; Google was also used frequently for easy access and fast search result. The accuracy and the recentness of information were the most significant criteria. Easy interface and convenient access were also considered important due to physicians' time constraints. Searching obstacles were divided into difficulty of searching system, unfamiliar term, too vast resources, difficulty to get fulltext articles and complex advanced search features. The results of this study can be utilized as a basis for improving information service of library and curriculum development for physicians.

This study aims to examine what influence a career exploration group counselling program has on career decision-making self-efficacy and career maturity of female college students. As a result of the study, it was discovered that the career exploration group counselling program had statistically significant influence on goal choice, job information and future plan which are sub-variables of career decision-making self-efficacy while it had no significant influence on problem solving. Also the program had a statistically significant influence on decision, independency, and involvement which are sub-variables of career maturity while it had no significant influence on compromise. Such results show that the career exploration group counselling program had a significant influence on career decision-making self-efficacy and career maturity of the subjects. Therefore, it is suggested that the career exploration group counselling program should be properly developed and provided so that students can choose career which fit for their aptitude and ability. Further, courses for career exploration group counselling program should be provided at universities to help them with career.

In developing information systems, omissions and redundancies of user requirements are too frequent to increase development cost as they need to be remedied at later stages. In order to cope with this problem, various tools describing business processes have been proposed in the past and yet fewer attempts have been made to systematically and categorically evaluate performance of individual tools describing business processes. In this paper, we offer a general framework for appraising competing tools for describing business processes, including ERD, DFD, and Use Case Diagram in terms of ease of use, completeness, chance of having omissions, and. Based on a exemplary business From the measures proposed in this paper for comparing descriptive tools, ERD turns out to stand out over other often-used methodologies. Despite its problem with poor readability, ERD proves to offer relatively higher expressive power and ease of use. Being supplemented by well-formed job descriptions, ERD would remain a better choice in developing business information systems.

In today's rapidly changing business environment, corporations need to have flexibility in order to survive. This was especially true of Korean firms that were affected by the policies of the International Monetary Fund(IMF) since 1997. IMF requirements became a catalyst that helped Korean firms design their HR practices more rational and efficient. Although these changes increased the firms flexibility and global competitiveness, they also brought some harmful effects. Job insecurity is one of the most serious problems in Korean firms and in the greater Korean society, As today's organizations no longer lifelong employment, individuals put stress on psychological satisfaction with the need to manage one's career and employability in the open labor market rather than rapid promotion or high compensation in a organizations. Theoretically and empirically, the topics of career choice and career development were extensively developed. On the other hand, the issue of career commitment received little attention. The purpose of this study is to examine the preceding factors career commitment among public officials in Korea.
