Benign and malignant tumors are found in the foot, although the incidence is low. The most common bone tumor in the foot is osteochondroma, which is thought to develop in bones that form through the process of enchondral ossification. In particularly, osteochondromas in the foot mostly occur in metatarsal bones and phalanges. It is seldom found in talus. It is usually confused with osteophyte or enthesis. We report an osteochondroma case confirmed by roentgenographical and pathological investigation, after removing the masses form bilateral tali of a 19-year-old male patient presented with bilateral ankle joint pain for three years.

코로나19 팬데믹 이후 배달 앱 사용량이 증가에 따라 배달 오토바이 수가 급증하면서 이와 관련 사고 또한 급격히 증가하는 추세를 보이고 있다. 특히 청각 장애인들은 도로에서 이러한 종류의 사고 위험에 더욱 노출되어 있으며, 이 문제를 해결하기 위해 구글 앱 인벤터를 사용하여 도로에서 오토바이 소리를 인식하는 인공지능 학습 모델을 개발하였다. 개발된 어플리케이션은 도로에서 오토바이 소리를 감지하고 사용자에게 진동과 사진으로 알림을 보냄으로써 사고를 예방에 기여할 수 있다.

Intussusception in adult is a rare disease and laparotomy is usually considered because of the probability of malignancy. Especially with obstruction symptom or sign, it might be needed emergency operation. This case was a simultaneous development of small bowel intussusception and acute hepatitis A. The patient had abdominal pain and vomiting. Intitial laboratory examination with elevated aminotransferase revealed that the diagnosis was acute hepatitis. As managing acute hepatitis, the abdominal pain was not improved and the patient had tenderness on periumbilical area on physical examination. A jejunal intussusception with a lead point was proved on the abdominal computed tomography scan. Fortunately, symptom of intussusception was relieved while nulli per os (NPO) and intravenous hydration. After recovery of acute hepatitis, laparotomy was done. The lead point was $2.5{\times}3.0cm$ sized hamartoma. This was the case that the symptom of intussusception was confused with that of acute hepatitis.

This study was performed to evaluate economic effect of the water fluoridation program in Cheong-Ju City from 1982 to 2010. To study this economic effect, this study used cost-benefit analysis methodology from eight years old to fourteen years old in Cheong-Ju City. Major findings were as follows; First, total cost of fluoridation program in Cheong-Ju City was 1,384,164,734 korean won and total benefit was 15,057,426,621 Korean won from 1982 to 2010. Second, total cost which was converted by present value 2000 year was 1,687,412,718 won and total benefit which was converted by present value 2000 year was 14,582,548,519 Korean won. Cost-benefit ratio was 8.64. Net present value which happened from 1982 to 2000 was 7,990,710,155 Korean won and cost benefit ratio was 7.47. In conclusion, by the above result, economic impact of the water fluoridation program was very effective for children in some area of Cheong-Ju city.

Purpose: This paper analyzes the results of arthroscopic bankart repair for anterior recurrent dislocation following a trauma on shoulder. Material and Methods: The subjects were twenty-three (23) cases that were available to follow up for more than eighteen months during the period from November 2001 to June 2003 and were chosen from patients to whom arthroscopic bankart repair was applied using a knotless suture anchor for their traumatic anterior recurrent dislocation on the shoulder. Their average age was 28 (ranging from 15 to 60) with 20 males and 3 females. The injury from sports activities accounted for the most cases with 14 subjects. The average follow-up period was 27 months (ranging from 18 months to 35 months). There were 19 cases of bankart lesions, 4 cases of ALPSA lesions and associated with 5 cases of partial tear in the rotator cuff. The anchors employed were knotless anchor (Mitek) for all the cases. Rowe scoring scale was adopted to judge the results after operations. Patients' subjective satisfaction and range of motion of external rotation were addressed together. Results: Rowe scores showed that 20 cases (87%) reaches the level of 'good' and hinger. The average patients' satisfaction accounted for 90 points out of 100. It was also found that external rotations averagely decreased by 6.5 degree when the range of motion was in at the side. Conclusion: There were satisfactory results of arthroscopic bankart repair using knotless suture anchors as an operative treatment for traumatic anterior recurrent dislocation on shoulder.

In this paper, we describe not only extraction method of moving object by difference image but also automatic target tracking algorithm. Proposed algorithm track the moving target by the calculation of moving target's center. The results show that this algorithm can apply to practical device such as real time target tracker.

The purpose of study is to suggest the data on what residential choice elements have to be considered to be important when the apartments are planed in middle size cities. This study analyzed the environmental characteristics of Cheong-Ju city and compared the priority of residential choice elements by using AHP(Analytic Hierarchy Process). The results of analysis are as follows. 1) The rate of housing supply in Cheong-Ju city is low at $80.2\%$ and concentrated on small sized apartments. Furthermore, the educational and traffic facilities are very insufficient. 2) While residential choice in Cheong-Ju is heavily characterized by educational surroundings, it is less affected by economic aspects such as housing prices and the value of investments and accessibility to public transportations, distance to working places. 3) It is affected by residents' general characteristics like as sex, age, life cycle, education level, properties, home ownership, number of room and type of house they want. In conclusion, the middle size cities like Cheong-Ju need the large scale residential plans connected with educational considerations, focused on improvement in quality and outdoor space. In addition, it is recommended to make plans to satisfy the diverse needs of consumers.

This study conducted an analysis of importance levels and also an AHP analysis based on the results of the monitoring (from Aug 2011 through Feb 2012) carried out in the Sajik 2-dong in the City of Cheong-ju. By quantitatively eliciting the effects that the urban regeneration projects that use art programs have on the changes in the perception of community housings and by analyzing the results of objective verification, this study was able to ascertain that local resident festivals had the greatest impacts on the change in the perception of community housings in the Sajik 2-dong in the City of Cheong-ju. This is deemed to be attributable to the fact that programs such as local resident festivals, in which various age groups participated, - amidst the unmitigated circumstance of Sajik 2-dong in the City of Cheong-ju (conflicts among the residents on account of redevelopment project) - exerted significant influences in the perceptional change of the community and in the resolution of conflicts.

This study aims to clarify the transformation of urban spatial structure around old castle in cheong-ju city. The urban spatial structure is composed with road system, block division, and lot system with original cadastral map in 1913 and 2011 GIS. Transformation of road system is classified into control of road line, construction and extension of road. Construction of arterial road was divided into Nam-juro and Mang-sunro with 2 blocks and lot system was destoyed. Transformation of block has not been developed except 4 blocks. The 4 blocks were divided into east-west or north-south direction and became 8 blocks. Transformation of lot system is classified into maintained, subdivided, and destroyed lots in shape and size of lots. Maintained lots were found in large lot in size for public office and park. Subdivided lots were mainly represented with the existing main road, an active alleys, and so on. Destroyed lots by road construction and extension were showed in Nam-juro. Although all these transformations are used to enhance urban spatial structure. The old systems have remained around old castle in cheong-ju city.

Myxoma is a benign mesenchymal neoplasm that can occur in the head and neck. Laryngeal myxoma is extremely rare and easily confused with a laryngeal polyp. The common clinical presentation is hoarseness, dysphonia, dyspnea and dysphagia depending on their size and location. Treatment for laryngeal myxoma is complete surgical excision with surrounding normal tissue. To our knowledge, 11 laryngeal myxomas have been reported in the English literature, and all patients except only 1 case were male. We report the second female case of myxoma on a vocal cord with a review of literature.
