This paper proposes an automated crack evaluation technique for a high-rise bridge pier using a climbing robot. The proposed technique enables to automatically detect and quantify the bridge pier cracks even where cannot easily access by human for visual inspection. To achieve it, high quality images are obtained by scanning the vision cameras embedded on the climbing robot along the bridge pier surface. Then, a feature extraction-based image stitching algorithm is newly developed and applied for establishing the entire region of interest (ROI) images. The ROI images are then processed with a semantic segmentation algorithm for automated crack detection. Finally, the detected cracks are precisely quantified by a crack quantification algorithm. The proposed technique is validated using in-situ test data obtained from Jang-Duck bridge located at Gangneung city, South Korea. The test results reveal that the proposed technique successfully evaluate the bridge pier cracks with precision of 90.92 % and recall of 97.47 %.

실록산 重合促進에 관한 대메칠썰포옥사이드의 效果에 관한 硏究

裵長淳 단국대학교 1987 論文集 Vol.21 No.-

Polymerization of siloxane can be implemented by application of acid alkali as catalysis however according to amterials various methods should be searched. The study revealed that for the polymerization of siloxane application of dimethylsuloxide has more effectiveness than that of acid, alkali. The experimentation has been undertaken by transformation of density of sulfoxide according to number of mole of siloxane and then experiment on the extent of polymerization caused by changes of temperature and time.

This study aimed at examining university students' interest in etiquette instruction and an etiquette instruction plan and analyzing the relationship between the interests of the content of etiquette instruction and the instruction plan. The results of the study were summarized as follows: 1. University students received a mean of 3.48 point out of 5 in the measurement of their interest in etiquette instruction. Of 16 items on etiquette instruction, language etiquette received the most interest, followed by workplace etiquette, behavior etiquette, family etiquette, funeral rite etiquette, greeting etiquette, school etiquette, dining etiquette, wedding ceremony etiquette, reception etiquette, costume etiquette, festival etiquette, ancestral rite etiquette, public etiquette, birthday etiquette, and a coming-of-age ceremony etiquette. 2. University students received a mean of 3.69 point out of 5 in the measurement of their interest in the etiquette instruction plan. Of 10 items on the etiquette instruction plan, 'The content of etiquette instruction should be applicable in daily life' and 'Instruction place should be equipped with enough practice tools' took joint first place, followed by 'The content of etiquette instruction should be easy to understand', 'The instructor should be a professional etiquette educator', 'Students' opinions should be reflected in the content of instruction', 'Theory and practice were taught in parallel', 'Etiquette instruction-related media should be provided', 'Etiquette instruction-related information or material should be easily available', 'Theories on etiquette instruction should be systematic', and 'A specialized textbook should be used in etiquette instruction'. 3. The analysis of the relationship between the interests of the content of etiquette instruction and the etiquette instruction plan was performed. According to the results, each content of etiquette instruction had a somewhat high relationship with students' interest in the parallel of theory and practice, systematic theories, utilization of a specialized textbook, and easy availability of information/material.

선천성 낭성 선종양 기형은 태생 16주 이후 말단세기관지의 형성이 중단되어 미성숙기관지들과 중배엽성분들이 과도하게 증식하여 발생하는 드문 선천성 폐질환이다. CT소견은 낭종의 크기 숫자, 내용물 등에 따라 다양하나, 병변내에 정상적인 폐혈관이 보인 예는 전세계적으로 보고된 적이 없었다. 저자들은 역동적 흉부 CT상 균일한 저음영의 병변내에 정상 폐혈관상이 유지된 선천성 낭성 선종양 기형 1예를 경험하였기에 보고한다. Congenital cystic adenomatoid malformation(CCAM) is a rare pulmonary disease that is thought to be developed by abnormal proliferation of immature alveoli and other mesenchymal component from the abrupt halting of the terminal alveoli formation after 16 weeks of gestation. On CT scan, there are no consistencies regarding to size, numbers, and its contents but no cases were reported in past showing normal pulmonary vascularities. We reports a case of CCAM that showed normal pulmonary vascularities within the hypodense lesions on a dynamic chest CT

The process data are integrated and utilized for the production management, with the rapid development of analog measurement technology and with the wide spread of computer users. This trend draws more attention to the process data integration system which makes it possible to improve the quality of products, to classify and count the products automatically and to provide the basis for the production plan through the analysis and modification of process factors based upon the integrated process data. The system may be classified (either analog data of digital data) and the operating methodology of the system. Generally for the process control, it is necessary to set and monitor the reference and tolerance values of control-related process data, for example, temperature, rpm and pressure. In using the conventional analog controllers, it is not feasible to get the process data required for the quality control. Recently the digital controllers are developed. which have more accurate control capability and feasivility in getting the process data then the old controllers; the old are going to be replaced by the new. By utilizing the process data integration system, the analog controllers still can be used for the process control with the continuous quality improvement.

An experiment was made on an equilibrium mechanism of siloxane with a basic-catalyst of tetramethylammoniumhydroxide. In the equilibrium mechanism of siloxane, experiments were made on composition of reaction materials, mass ratio effect, effect of catalyst and equilibrium conditions resultant from reaction. Siloxanes used for these experiments were octamethylcyclotetra siloxane(D_4), hexamethyldisiolxane(MM), hexamethylcyclotrisiloxane(D_3), octamethyltrisiloxane(MDM) and decamethyltetrasiloxane(MD2M) etc. The reactions of siloxanes were diminishing in the order of D_4>MD_2M>MDM>MM.
