Branchial cleft anomalies are the second most common head and neck congenital lesions seen in children. Amongst the branchial cleft malformations, second cleft lesions account for 95 % of the branchial anomalies. This article analyzes all the cases of second branchial cleft anomalies operated on at Seoul National University Hospital from September 1995 to February 2011. We analyzed sex, age, symptom and sign, accompanied anomaly, diagnosis, treatment, pathologic report and outcome via retrospective review of medical records. In this series, we had 61 patients (27 female and 34 male). The mean age at the time of operation was 38 months. 31 lesions were on the right, 20 were on the left and 10 were bilateral. The most frequent chief complaints at presentation were non-tender mass and cervical opening without any discharge. According to anatomic type, 29 patients had branchial cleft sinuses, 14 had cysts, 14 had fistulas and 4 had skin tags. Complete excision was attempted if possible and antibiotics challenged when infection was suspected. Complete excision was achieved in 96.7 % of cases. Incision and drainage was done in 2 cases due to severe inflammation, and both recurred. Postoperative complications included wound infection in 2 cases. Microscopic examonation revealed squamous epithelium in 90.2 % and squamous metaplasia in one case in the branchial cleft cyst wall. In summary, second branchial anomaly is found more frequently on right side of neck. Fistulas are diagnosed earlier than cystic forms. Most cases could be diagnosed by physical examination. The definitive treatment is complete excision and sufficient antibiotics coverage for cases with inflammation. After drainage of infected lesions, follow up excision after 1 year might be beneficial for preventing recurrence.

본 연구에서는 떡 굳음방지기술의 적용성 확대를 위하여 멥쌀 대신 메밀 분말을 0, 15, 30, 45%로 대체한 가래떡을 제조 후 4℃에서 3일간 저장에 따른 텍스쳐, 색도, 기호도 검사를 분석하였다. 일반공정을 사용하여 제조한 떡의 경도는 메밀 분말 대체량과 무관하게 모두 저장 기간에 따라 급격하게 증가한 반면, 떡 굳음방지기술을 적용한 경우에는 메밀 분말 45% 대체한 가래떡을 제외하고 저장 기간이 증가함에 따라 경도 상승이 억제되어 제조 직후의 경도를 유지하였다. 메밀 분말 대체량이 증가할수록 명도는 감소하고, 적색도 및 황색도는 증가하였다. 떡 굳음방지기술을 적용한 가래떡의 전반적인 기호도는 제조 직후에는 메밀 분말을 함유하지 않은 가래떡이 가장 높게 나왔으며, 메밀 분말 대체량이 증가할수록 기호도는 저하되었으나 저장 3일 후에는 0,15% 메밀 분말 대체 가래떡이 유의적 차이가 없었다. 따라서 본 연구에서는 일반공정보다는 굳음방지기술을 적용한 메밀 분말 대체 가래떡 적용이 전반적 품질 면에서 유리하며 떡 굳음현상 지연은 메밀 분말 대체량 30% 정도까지 적용 가능하며 전반적 기호도 및 텍스쳐 측면에서는 15%가 적합하였다. Garaedduk made with various levels of buckwheat flour (0, 15, 30, and 45%) for rice flour was prepared using retrogradation-retardation technology and their physical and sensory properties were investigated. The moisture content of garaedduk decreased and the color differences increased as the ratio of buckwheat flour to rice flour increased. During storage at 4℃, the hardness values of garaedduk made with 15 and 30% buckwheat flour were maintained for up to three days. Immediately after manufacture, garaedduk made with higher levels of buckwheat flour had reduced overall acceptability. However, there was no significant difference in the overall acceptability of garaedduk made with 0 and 15% of buckwheat flour after storage. Therefore, buckwheat flour can replace rice flour with retrogradation-retardation technology to inhibit the starch retrogradation of garaedduk, which maintained its overall quality at a buckwheat flour level of 15%.

Hierarchical IPP (Integrated Path Planning) combining the GPP (Global Path Planner) and the LPP (Local Path Planner) is interesting the researches who study about the mobile vehicle in recent years. However, in this study, there is the path mismatch problem caused by the difference in the map information available to both path planners. If ever a part of the path that was found by the GPP is available to mobile vehicle, the part may be unavailable when the mobile vehicle generates the local path with its built-in sensors while the vehicle moves. This paper proposed the TWR (Temporal Waypoint Reviser) to solve the path mismatch problem of the hierarchical IPP. The results of simulation provide the performance of the IPP with the TWR by comparing with other path planners.

This paper presents the implementation of the time-delayed controller(TDC) for a robot manipulator in the Cartesian space. The time-delayed controller is usually implemented in the joint space due to the actual joint control implementation. However, when the Cartesian controllers are required such as force control applications, the TDC can be implemented in the Cartesian space since it requires only Jacobian. Experimental studies are conducted to demonstrate the performance of the Cartesian TDC and the difficulties of Cartesian TDC are addressed as the practical problem.

This purpose of this study was to investigate the effect of seniorbics program on the fall-related fitness and mental factors in the elderly women with experience of fall. For this study, senior women with experience of fall were divided into 2 groups (exercise group and non-exercise group), exercise group participated in the seniorobics program for 12wks. The results of fall-related fitness and mental factors were made a comparison between experimental group and control group. The results of this study were as in the followings. First, there was a difference of fall-related fitness factors(upper-body strength, lower-body strength, flexibility, whole body reaction, balance, and mobility) between groups. Second, there was a difference of fall-related mental factors(depression, falls efficacy, and fear of falling) between groups. Third, the effect size presented in the orders ofwhole body reaction, lower-body strength, balance, and depression. These results suggest that seniorobics program is effective exercise on the fall-related fitness and mental factors for the elderly women with experience of fall. What`s more seniorobics is enough to get agility above everything else. Therefore seniorobics would be a useful tool for prevention of repetitive falls in elderly women.
