The aim of this study was to evaluate the musculo-skeletal symptomatic features of municipal sanitation workers and to compare differences of the musculo-skeletal symptoms by work types. We conducted descriptive cross-sectional survey concerning the musculo-skeletal symptomatic features of 315 street cleaners in Seoul and GyeongGi Province, Korea, during 2 weeks of September 2006. Questionnaires were consisted of general characteristics, occupational characteristics and musculo-skeletal symptoms. And we observed their works and evaluated their movement and posture by REBA. For work types, tools and subjective physical work loading, there were statistical difference whether or not NIOSH symptom positive on upper limb. Musculo-skeletal symptoms on upper limb were claimed from 43.2% of street cleaners, more than in 32.4% of cleaners. Musculo-skeletal symptoms on upper limb were reported higher in the group who felt their subjective physical work loading severe than in the otherwise group. The REBA results were over 'high risk stage' in street cleaners. Street cleaners had more repetitive motions than solid waste collectors on upper limbs. Works according to the criteria of musculoskeletal burdened work by the Ministry of Labor results were over 'high risk stage' of No. 2 and No. 4 in street cleaners. We found that street cleaners complained musculo-skeletal symptoms on upper limb more than solid waste collectors. This study suggests that it is necessary for street cleaners to carry out the prevention program of musculo-skeletal diseases. For street cleaner, the measure plans such as job rotation, automatic street sweepers, reducing work hours are helpful in preventing musculoskeletal symptoms on the upper limb.

Purpose: Gastric cancer is one of the most common cancers in Korea, and the proportion of upper-third gastric cancers has been steadily increasing over the last two decades. This study aimed to evaluate the effect of tumor location on gastric cancer prognosis. Materials and Methods: We retrospectively reviewed 2,466 patients who underwent gastrectomy for pathologically proven gastric cancer between January 2011 and December 2016. The patients were divided into an upper-third group (U group; n=419, 17.0%) and a middle- and lower-third group (ML group; n=2,047, 83.0%). Clinicopathological characteristics, overall survival (OS), and recurrence-free survival (RFS) after surgery were compared. Results: The U group had more advanced disease than the ML group and a higher incidence of N3b disease for T3 (12.0% vs. 4.9%, p=0.023) and T4 tumors (33.3% vs. 17.5%, p=0.001). The 5-year RFS rate for stage III disease was marginally lower in the U group than that in the ML group (47.1% vs. 56.7%, p=0.082). The upper third location was an independent prognostic factor for both OS (hazard ratio [HR], 1.350; 95% confidence interval [CI], 1.065-1.711) and RFS (HR, 1.430; 95% CI, 1.080-1.823). Conclusions: Upper-third gastric cancer shows extensive node metastasis compared to those located more distally in ≥T3 tumors. The upper third location is an independent prognostic factor for both OS and RFS and may have an adverse impact on RFS, particularly in patients with stage III gastric cancer.

본 연구에서는 2006년 홍수시 충주댐 운영에 따른 댐 상 하류의 홍수위 상승영향을 정량적으로 분석하기 위하여 팔당댐 상류의 한강 본류에 위치한 충주댐을 기준으로 상류구간과 하류구간으로 구분하고, 1995년부터 2008년까지의 홍수사상을 대상으로 모형을 검보정함으로써 수리학적 모형을 구축하였다. 구축된 모형을 이용하여 충주댐의 유무를 가정하여 충주댐의 홍수조절효과를 검토하고, 방류량의 변화에 따른 상 하류 주요지점의 수위 상승영향을 정량적으로 분석하였다. 분석결과, 2006년 홍수시 충주댐의 운영이 비교적 적절하게 수행되었음을 확인하였으나, 충주댐의 홍수조절효과는 댐 하류구간에 집중되어 있어 댐 상류 홍수피해 저감을 위한 제도적 보완이 필요한 것으로 분석되었다. 이러한 문제점을 해결하기 위하여 기존 댐 배수구간 상류 하천의 기점수위 결정방법의 한계를 검토하였으며, 댐 배수구간과 상류 하천의 계획홍수량 불연속을 반영할 수 있는 기점수위 결정방법을 제안하였다. 제안된 방법은 댐 상류하천의 홍수피해 저감을 위한 설계 및 홍수피해 발생시 피해원인 분석에 활용될 수 있을 것이다.

The aim of this retrospective study was to compare the amount of marginal bone loss between upper anterior area and upper posterior area with 71 upper single-tooth restorations on 2 stage machined $Br{{\aa}}nemark$ implants since Jan 1995. The second aim was to compare the bone defect group which had dehiscence and fenetration and the others in the upper anterior region. The results were as follows. 1. The most frequent reason of missing tooth in the upper anterior region was trauma by 61%. While upper posterior region showed various reasons such as congenital missing, advanced periodontitis, trauma. 2. Peri-implantitis with fistula occurred 1 of 41 implants in the upper anterior group in 1 year after loading and 2 of 32 implants in the upper posterior group failed before loading. The 1 year success rate of upper anterior group was 97.56 %, and 93.75 % for upper posterior group. 3. The mean marginal bone loss in the upper anterior group was 0.44${\pm}$0.25 mm, while 0.57${\pm}$0.32 mm in the upper posterior group. There was statistically significant difference in the amount of mean marginal bone loss (P${\pm}$0.10 mm at one year, and 0.48${\pm}$0.26 mm for the control group. No statistically significant difference of mean marginal bone loss was showen between bone defect group and the others at implantation. According to the results, the upper anterior region showed less marginal bone loss than the upper posterior region. In case of missing single upper tooth, careful consideration on recipient residual ridge to determine proper implant diameter and length, sufficient healing time, proper loading would lead to implant success. Single tooth implants in the maxilla seemed to be an alternative to fixed partial dentures without damage to adjacent teeth.

Upper canine is important because it protects and maintains the stability of the dental arch and also, joins the anterior with the posterior teeth. The incidence of impaction of upper canine is the second most frequent next to the third molar because it takes a long period of time to develop, and has a complicated path of eruption, and erupts lately. After the age of 10, clinical and radioglaphic examination can be used in revealing the possibility of impaction and efforts should be put to reduce the side effects. To prevent impaction, selective extraction of primary canine at the age of 8 to 9 could be considered and prolonged retention of primary canine in oral cavity should be avoided at this time. Once the impaction is iden, the first stage of the treatment is to lcocalize the lesion by radiographic examination and According to the severity, orthodontic traction or autotransplantation should be considered and comprehensive diagnosis and treatment plan of malocclusion should be established. Generally, labial impaction is due to arch length discrepancy and palatal impaction is due to malposition or morphologic pathosis of lateral incisors rather than arch length discrepancy. In surgical procedure, peridontal problems should be considered and the minimum amount of bone and soft tissue should be reduced and direct bonding method of many attachment methods should be recommended. Especially in traction of labially impacted canine, it should be guided to erupt through the keratinized zone and proper forced magnitude should be applied. The importance of periodontal condition should always be in mind following the patient education to mintain the good oral hygiene at each stage of treatment. Properly managed impacted canine can provide function and esthetic by proper diagnosis and treatment if extraction of canine is not indicated.

This study was conducted to investigate the influence of the topping time and height on the nonvolatile organic and higher fatty acid contents and the correlation among acid contents of tobacco plants. Within the topping time, the flowering (normal) stage of topping was the lowest in total analyzed acid (TAA), total nonvolatile organic acid (TNOA) and magic acid contents of NC2326, however, the highest in those of Burley 21 on 30 days after budding. Total higher fatty acid (THFA) and linoleic acid contents tended to be low with normal stage of topping. The lower the topping height, the lower the TAA, THFA and linoleic acid contents in middle and upper leaves (or NC2326 and Burley 21 were observed. On the other hand, the lower the topping height, the lower the TNOA and malic acid contents in middle and upper leaves for Burley 21 and upper leaves for NC2326 were found. There was a significant positive correlation between magic acid and TNOA contents. Similarly, TAA content showed a significant positive correlation with TNOA, oxalic acid and citric acid contents. But there was a negative correlation between malic acid and THFA contents. There were highly positive correlations among oleic acid, linoleic acid and THFA contents, respectively.
