This study researched a document regarding 'Pyeon (tteok)' on 25 Jong-ga ancestral ritual foods through "Jong-ga Ancestral ritual formalities and food", published during 2003~2008 by the National Research Institute of Cultural Heritage of Cultural Heritage Administration. A after about 10 years, the transmission process of the setting and recipe was compared and analyzed in 2015 by directly visiting 4 Jong-ga. This research classified regions into 7 Gyeonggi, 4 Chungcheong, 2 Honam, and 12 Yeongnam, and classified hakpa, Gyeonggi, Chungcheong, Honam region into 13 Gihohakpa, Yeongnam region into 12 Yeongnamhakpa. The important analysis standard of Jong-ga ancestral ritual food was the region and hakpa, which appeared to considerably influence 'Pyeon' setting style, which represents and symbolizes family and recipe. Gihohakpa Jong-ga, which is an academic tradition that pursues practical interests, seems to highly regard practicality to adapt to changes along with the period. On the contrary, Yeongnamhakpa Jong-ga, which highly regards self-sufficiency living base and moral justification, seems to be highly conservative. Increase in Jong-ga, which utilizes mill, is the result of adaptation to the period environment such as Jongbu aging and lack of labor, etc.

This study examined the traditional edible basis and ingredients of Song-gi used for Pyeon of Jong-ga ancestral ritual food. Through an investigation of references, a case study, and ingredient analysis for traditional edible basis of Song-gi, the nutritional value and availability as food material were reviewed. Among the 4 kinds of pine trees from 4,705 types of edible materials usable as food listed in the ${\ll}$Korea Food Standards Codex${\gg}$, 'Pinus radiata D. Don', in which the husk is acknowledged as an edible food, was applied in this study. This study processed the Song-gi following the method of jong-ga and divided into pine inner bark (PIB) and pine inner bark powder (PIBP) to analyze the general composition and dietary fiber. The main composition of PIB was carbohydrate, in which the content was 88.7% per 100 g. The content of dietary fiber was 73.7% per 100 g and the insoluble dietary fiber reached 92.3% in total dietary fiber. In conclusion, the edibility of Song-gi, which has a considerable amount of insoluble dietary fiber caused constipation because it absorbed the moisture in the intestine due to the lack of nutrients but may be developed as a functional food that helps the digestive activation of the intestine and improve the health of the intestine if taken with balanced nutrition.

Turbulent properties of the wake of a circular cylinder were measured The diameter of the cylinder is l0mm and the Reynolds number is 420. A new 3D-PTY system was constructed and a genetic algorithm (GA) was introduced in order to increase the number of instantaneous three-dimensional velocity vectors. In the GA two fitness functions were introduced in order to enhance the correspondences of the particles. The measurement system consists of three CCD cameras, Ar-ion laser, an image grabber and a host computer. More than 3000 instantaneous three-dimensional velocity vectors were obtained by the system. The database of the turbulent properties of the circular cylinder was constructed by the constructed 3D-PTV system.

This study conducted a literature review, field study, and in-depth interview on the build order, cooking method, and origin of 'Donggot-tteok (rice cake)', which was the ritual food for 'Chungjae Gwon Beol from the Andong Gwon clan Jong-ga' in Bonghwa, Gyeongbuk, who deifies Chungjae Gwon Beol as Bulcheonwi. Donggot-tteok of Chungjae Jong-ga is classified as one kind of Bonpyeon (Janjeolpyeon) and 11 kinds of Utgipyeon, and assumes a unique circle build shape. According to the results of the literature review data in 2004 and 2010 with field study data in 2014, the build order, materials, and cooking method were maintained without large changes. With regard to Utgipyeon with which Donggot-tteok is topped, Cheongjeolpyeon, Milbiji, Songgisongpyeon, Gyeongdan, Ssukdanja, Bupyeon, Japgwapyeon, Jeon, Sansim, Jo-ak, and Kkaeguri were heaped in each layer, and the beauty of obangsaek (five colors) was well harmonized. Besides, with regard to the origin of Donggot-tteok, which was presented without elaborating sundry records, we examined the possibility of being introduced from the royal court through old paper and the Jokbo (family tree) that Jong-ga owns.

A 4D-PTV system was constructed. The measurement system consists of three high-speed high-definition cameras, Nd-Yag laser and a host computer. The GA-3D-PTV algorithm was used for completing the measurement system. A horizontal impinged jet flow was measured. The Reynolds number is about 40,000. Spatial temporal evolution of the jet flow was examined and physical properties such as spatial distributions of vorticity and turbulent kinetic energy were obtained with the constructed system.

A 4D-PTV system was constructed. The measurement system consists of three high-speed high-definition cameras, Nd-Yag laser(10mJ, 2000fps) and a host computer. The GA-3D-PTV algorithm was used to extract three-dimensional velocity vectors in the measurement volume. A horizontal impinged jet flow was measured with the constructed system. The Reynolds number is about 40,000. Spatial temporal evolution of the jet flow was examined in detail and physical properties such as spatial distributions of vorticity and turbulent kinetic energy were obtained with the constructed system.

A new stereoscopic PIV has been constructed using two CCD cameras, stereoscopic photogrammetry, and 3D-PTV principle. The capability of the developed stereoscopic PIV was verified through a test on the Standard Images which are provided on the website of VSJ. The arrangement of the two cameras was based on angular position For the acquisition of 3D velocity vectors, 2D velocity vectors were obtained using the gray-level cross-correlation method from the two camera images and they were matched stereoscopically. The wake of a circular cylinder was measured and turbulent properties were presented.

A Hybrid-Genetic-Algorithm based 3D-PTV has been constructed by introducing the conventional GA-3D-PTV. The measurement system consists of two-high-definition-cameras(1k ${\times}$ 1k), a Nd-Yag laser and a host computer. The system has been used to measure the wake of a cylinder. The Reynolds number is 1120. The structures of the wake have been quantified in detail than the results obtained ever before.
