  • New product development has been a key element fur organizational evolution. The bulk of research about new product strategy has focused solely on new product development function itself. This paper investigates cross-functional elements in new product development. More specifically, we suggest that there must exist a fit between new product strategy and value chain strategy. It means that, in order to support new product development activity, there must exist a relevant value chain strategy. We consider three types of integration - internal integration, customer integration, and supplier integration - as strategic elements of value chain strategy. For the case of new product strategy, we consider market newness and product technology unfamiliarity as strategic elements. We also consider two types of learning characteristic, i.e., \\\"fast-adaptive learning\\\" and \\\"slow-adaptive leaning\\\" as control factor. Learning characteristic represents firms organizational capability related with organizational learning. For example, fur fast-adaptive learning case, the effect of integration appears early in time. System dynamics simulation is employed to verify our research framework. The results exhibit that there must exist cross-functional relationships between value chain strategy and new product strategy in order to shorten total development time.al development time.

  • This study examined the effect of ergonomic heel rest that was designed for drivers who have physical handicap in the low leg muscles or have to drive prolonged hours with frequent foot pedaling. An experiment was designed to test the ergonomic heel rest with traditional foot pedal. Forty subjects participated in the experiment. Electromyography(EMG) was used to monitor the muscle activity and fatigue of right leg, and Electro-goniometer was used to measure the ranges of motions of the knee and ankle. A simulator of driver's seat was built for the experiment and the heel rest was installed on it. In order to examine the low muscle activity and range of motion, subjects used the foot pedal for 15 minutes repetitively for each experimental condition. Another 15 minutes test without the heel rest was also performed for comparison. The Root Mean Square(RMS) and Mean Power Frequency(MPF) Shift were used to quantify the level of muscle activity and local muscle fatigue. In results, statistically significant decreases of muscle activity and fatigue were found in all the low leg muscles. The range of motion of the knee and ankle joint also decreased when the heel rest was used. The mechanism of the heel rest effect was discussed in this study. This type of heel rest can be applied to real driving situation after ensuring the safety, or overcoming the psychological discomfort possibly due to unfamiliarity.

  • Modern clothes are part of formative arts and express experimentation and originality. This tendency is especially prominent in structural fashion. This study set out to analyze structural fashion in various aspects, examining and analyzing the expressive and formative characteristics of Deformation and contribute to the development of creative fashion design. The approach of peer debriefing was used with three fashion experts to identify structural clothes in the women's haute couture collections from a total of 24 seasons from S/S of 2008 to F/W of 2019. The clothes with Deformation characteristics were then identified to analyze expressive and formative characteristics. The expressive characteristics of Deformation in structural clothes were exaggeration, distortion, and recombination. Exaggeration was expressed with exaggerated sizes, forms, and excessive use. Distortion was expressed with distorted forms and functions and through optical illusions. Recombination was expressed with the recombination of forms and roles. The formative characteristics of Deformation were maximum, playfulness, and unfamiliarity. The study connected the expressive characteristics to the formative ones and examined them simultaneously, finding that "distortion" and "playfulness" represented the expressive and formative characteristics, respectively. The characteristics of Deformation are expressed in various ways in structural fashion. If they are considered, they will make valuable contributions to creative ideas.

  • This study has confirmed that subjective positive and negative aspects a driver feels by applying haptic seat on a vehicle to substantiate vehicle navigation system. Our experiment with total twenty subjects provides that the reaction time (RT) is superior in haptic interface than visual or auditory interface but subjective satisfaction, which subjects feel, and workload is less low in a simulator environment. Although, the difference of individuals and unfamiliarity is relatively high inasmuch as the experiment of absolutely new technology, but overall satisfaction of haptic seat is high. The result of study provides some consideration and direction to need in implementation of a haptic seat and it also confirms their possibility meaningfully. We expect the interaction between a driver and a vehicle and safety improvement potentially through applied haptic seat on actual vehicles.

  • Design-build (D&B) has been broadly perceived as an effective project delivery method and become popular in the world. However, the implementation process of this innovative procurement method in Vietnam encounters difficulties due mainly to unfamiliarity and inexperience with the approach. Critical success factors (CSFs) which could be used to enhance the project execution are useful to practitioners in Vietnam if identified. A questionnaire survey was employed to identify CSFs of D&B projects in Vietnam. Parties' competence, especially financial capability, and contract documentation are the most important factors significantly affecting project success. It was also shown that the perspectives of two principal parties in D&B projects on the CSFs are statistically correlated. The identified CSFs were then validated with some various D&B projects. The execution results of CSFs' were compared with the projects' performance measured try key performance indicators (KPIs). The most important success factors of this study were also compared with other countries'. The validation and comparison results provide project participants with some useful information to perform D&B projects better. Practitioners should well perform the identified CSFs to enhance the chance of the success of D&B projects in Vietnam. The findings of this study are useful not only to Vietnamese practitioners but also to others who are concerned about D&B method and plan to employ it in Vietnam in future.

  • This paper explored how university students viewed flipped learning from their own perspectives. Using qualitative research methods, 5 students from a Computer Graphics course at a mid-scale university in Seoul were interviewed for this purpose. Researchers collected data about their learning experiences, emotions, and reflections about flipped learning in general and its components such as online materials, in-class activities, and instructor guidance. Research findings indicated that students were not so much conscious about the unfamiliarity of the class, the increased work load, nor the online lectures. They rather prioritized 'what they could actually learn' from the course, and thus defined flipped learning as a method which enabled students to constantly check and fill in the gaps in their learning through team-based activities and prompt feedback from the professor. A combination of students' positive attitude and active participation in team-based activities, the overall atmosphere of the department which supported interactivity and collaboration, the professor's emphasis on learning-by-doing and student-centered learning appeared to form their notions of flipped learning. The use of technology did not appear to heavily impact students' conceptions of flipped learning. Researchers suggest that pedagogical beliefs of the professor, culture surrounding the learner, and the good match between the course content and instructional strategies are central for designing a successful flipped learning class.

  • In spite of rather short history of about 10 years, Engineering Accreditation has been spreaded, drastically. Considerable number of faculties in diverse engineering majors keep pouring their efforts for better engineering education. Nevertheless, due to unfamiliarity to certain terminologies that can be easily found in other areas, major number of engineering faculties suffer from difficulties in fulfilling the requirements for Engineering Accreditation. This paper presents fundamental knowledge underlying Accreditation Standards and requirements of each Standard, in detail. This paper eventually provides engineering programs with concrete ways by which one can fulfill all the requirements for Engineering Accreditation.

  • Objective : This paper is aimed at suggesting further tasks by checking and rectifying the errors of the ancieut Chinese-vernacular Korean translations of Park Ji-won(朴趾源)'s "Kumryosocho". Method : In order to correct the wrongly transcribed "Kumryosocho" was contrasted with the original "Xiangzubiji(香祖筆記)", of which the part is "Kumryosocho". And then the errors and mistakes are discovered in published ancient Chinese-to-vernacular Korean translations. Result : In the course of checking the existing translations of "Kumryosocho", this paper identified the following types of errors. 1. Errors attributable to unfamiliar names of medicinal herbs 2. Errors due to the unfamiliarity with the names of diseases or symptoms in Traditional Koreau Medicine(TKM). 3. Errors committed in hand transcription. These types of errors were committed as well in translating jargons routinely used in TKM books. To the surprise, the errors above have been repeated even in the latest version of its translation. This means that the medicine-related materials by Silhak scholars, including "Kumryosocho", were placed at a dead zone of the research between Chinese classic scholars and TKM scholars. Conclusion : To minimize errors and mistakes, it is needed to activate the cooperative work of heterogeneous experts in two academic fields.

  • The purposes of this study were 1) to identify predictors of consumers′ apparel purchase on Internet shopping malls and 2) to determine reasons that respondents didn\`t have purchase intention of apparel on Internet shopping malls. The data were collected via a self-administered questionnaire from 204 male and female students who experienced shopping for apparel on Internet shopping malls, living in Cheju and analyzed by factor analysis, multiple regression analysis, t-test and paired t-test. Two predictors were found regarding purchase of apparel on the "big box" Internet shopping malls which sells various product categories; apparel quality and fun of order process. On the speciality Internet shopping malls which sells only fashion goods, diverse apparel assortment and easy handling and fun of information search were identified as predictors of apparel purchase. Reasons that respondents didn′t have purchase intention of apparel on Internet shopping malls were summarized and labeled as: difficulty of decision making due to virtual shopping environment, insufficiency of diverse apparels, users′ unease handling, risk of incredible apparel quality, unfamiliarity of Internet shopping and risks of unsecurity. Difficulty of decision making due to virtual shopping environment was determined as the most important factor of reasons that respondents didn′t have purchase intention of apparels in website.

  • The new Urban Park Regulation encourages local governments to introduce new types of urban parte such as historic parte, cultural parks and neighborhood parte. However ambiguity among those parks in terms of main facilities and providing recreational programs makes it difficult for local governments, as well as landscape designers and planners, to adopt this new regulations. In this light, the present study aims to search for park facilities and programs defined by the new regulations, in order to satisfy users' demands for those parks with consideration to parks' unique characteristics. For these purposes, a conjoint analysis was carried out with three hundreds participants. Sampled participants include the citizens of Seoul as well as current residents of Paju. The study results indicate that participants would like to have distinctive programs and facilities at these three new types of parks. However, no considerable differences were observed among the levels of programs and facilities participants wish to have, due to unfamiliarity with, in particular, cultural and historic parks. Despite this insignificant difference among attribute levels, study results clearly suggest that residents wold like to have new types of facilities and recreational programs.
