This study sought to prove the validity of Hansik Yangnyomjang classification Korean culinary education. survey was conducted among Korean Cuisine professionals, culinary instructors, culinary professionals and potential students from various backgrounds. ata were collected by self-administered questionnaires and analyzed by reliability analysis, frequency analysis and t-test. any differences in terms of the validity of Hansik Yangnyomjang classification between groups based on their majors, teaching experiences, and knowledge of sauce classification. First, the result showed that fermented Jang is core element Korean cuisine. Second, Hansik Yangnyomjang classification needs to be organized around Balhyojang. Third, Hansik Yangnyomjang classification for beginners and foreigners who want to learn Korean Cuisine relatively easily. Finally, the term ‘sauce’ is not suitable for replacing Yangnyomjang.

Passenger cars with sunroofs sometimes experience a low frequency noise called "wind throb" and a high frequency called "turbulence noise" when travelling with the sunroof open. These noise should be suppressed because it is an unpleasant noise which can adversely affect the acoustic environment inside a car. It is useful to suppress the wind noise if the height of a wind deflector can be adjusted variably in a proper position depending on the driving speed and the sunroof opening width, because it is always sprung out to a fixed height at the front edge of sunroof when opened. In this study, a variable sunroof wind deflector was developed and verified by road test and durability test. The deflector's optimal basic sectional shape and variable height according to sunroof opening width were determined by CFD analysis.

In order to control vibration in structures, it is desirable to be able to identify dominant paths of vibration transmission from sources through the structure to some points of interest. Structural intensity vector(power flow per width of cross section) using cross spectra is able to measure the vibration power flow at a point in a structure.<br/> This paper describes the possibility of the application of structural intensity measurement to identify dominant paths of vibration power's transmission for vibration control. Structural intensity of 2-dimensional structure can be obtained from two point measurement per axis on the assumption of far field. Experimental results are obtained on a passenger car's hood panel on idle operation. The structural intensity vectors on the panel showed good possibility to identify the path of vibration power flow on idle operation.<br/>
