Most of the changes found on the toi-maru of the Sang-chun-heon Historic House indicate that the upper structure of the toi-maru of the late Joseon Dynasty houses where toi-bo was installed was not completed in an instant. Toi-maru with stud is especially typical in 3-Dori type Structure, and can be found in many historic houses in Yang-dong Village, where the many 3-Dori type Structure is located. This type can be interpreted as the intermediate type that began at the eaves was settled as a toi-maru with a separate toi-bo. It seems that the toi-maru in front of the on-dol room at the time of the construction of the Sang-chun-heon historic house would not have been the same as it is now. The members dividing the on-dol room, the walls, and the various incomplete appearances seen in the window composition can be construed as traces of the change. The fact that all three types of houses that occurred during the spread of toi-maru after the mid-Joseon Dynasty can be examined can be added to the existing evaluation of cultural property houses in Yang-dong Village.

Jeong Geuk-in was a poet of the early Joseon period. He lived for 45 years before Hangeul was published and 35 years afterwards. So, he wrote poetry both in Chinese and Korean. He was a creative writer who wrote Korean poems and songs. There were only a few works written in Korean including and before him. His Korean poems are , and . He created Korean poems and songs by unifying three literary forms of Sijo, Gyeong-gi-che-ga and Gasa. This study was intended to examine written in Korean. For the study, the form of the Bul-woo-heon-ga was analyzed and it was considered as Saseolsijo (a form of sijo with no restrictions on the length of the first two verses) for genre classification. However, it is generally thought that the Saseolsijo appeared in the seventeenth century. Therefore, this study is to explain the reason why Bul-woo-heon-ga is included in Saseolsijo. Another problem is that the writer of Bul-woo-heon-ga is not Jeong Geul-in, because of the fact that the speaker who appears in Bul-woo-heon-ga admired Jeong Geuk-in. In general, people do not admire themselves. As Jeong Geuk-in is a subject to be admired in the book, it is thought that the writer of the book is considered as one of his pupils or friends.

In this paper, double Cylindrical type ozonizer has been designed and manufactured to improve ozone yield by cooling external electrode. The ozonizer equipped with three electrodes ( central, internal and external electrodes ). Discharge and ozone characteristics are described in this paper by varying the flow rate( Q ) of oxygen supplied gas, temperature of cooling gas and supplied voltage.

Prediction of fatigue duration is attainable from the analysis of the growth rate of the fatigue crack, and the property of the fatigue crack growth is determined by the calculation of the stress intensity factor. And the evaluation of the stress intensity factor, K comes from the stress analysis of the vicinity of crack tip of the continuum. This study describes a simple method to decide the stress intensity factor for the small crack at the sharp edge notches. The proposed method is based on the similarities between elastic stress fields of the notch tip described by two parameters, the stress concentration factor K, the radius of arc of the notch. And it is applicable to the analysis of the semi-elliptical penetration cracks and the edge notches.
