Objective: Occupational medicine specialists in the Busan, Ulsan and Kyung-Nam areas established an area-based occupational disease surveillance system and used this system to collected case information for the purpose of preventing occupational diseases Methods: l l hospital participated in this system. The authors selected five main diseases, which were hand-arm vibration syndrome (HAVS), work-related musculoskeletal disorder (WRMSD), occupational asthma, occupational skin disease and occupational and occupational lung cancer and established their case definitions. All cases were reported on the web, and real time analysis was conducted. Results: Between April 2001 and April 2003, 192 cases of HAVS, 118 cases of WRMSD, 33 cases of occupational asthma, 17 cases of occupational skin disease and 17 cases of occupational lung cancer (for a total of 377 cases of these five main diseases) were reported. most of the HAVS cases came from shipbuilding, and 172 of them (92.7%) were associated with grinding. Of the four main types of WRMSD, carpal tunnel syndrome (CTS) was the most prevalent with 46 cases and shipbuilding was also the main industry involved (83.9%). The ergonomic risk factors involved mainly associated with the hand. In 19 (57.6%) and 4 (12.1%) cases of occupational asthma, the agents involved. The causative agents of occupational lung cancer included Cr, welding fume, PAH, Ni, etc. 10(58.8%) of the cases were diagnosed as squamous cell carcinoma and 5(29.4%) as adenoma. Conclusion: This result showed that an area-based occupational disease surveillance system might provide an effective method of evaluating the prevalence of such diseases, however the Busan, Ulsan and Kyung-Nam provinces are too large to be treated as individual areas. Therefore, the authors suggest that each province should establish its own surveillance system.

김호기(Kim, Ho-Kee),김지현(Kim, Ji-Hyun),곽윤철(Kwak, Yun-Chul),정창무(Jung, Chang-Mu) 대한국토·도시계획학회 2012 國土計劃 Vol.47 No.2

This research is follow-up study of Kim Ji-Hyun?Kim Ho-Kee?Jung Chang-Mu(2010) and Kim Ji-Hyun?Kim Ho-Kee(2010). The fields of technology for applying to U-City are extensive and each type of technology within the sector is diverse. Such being the case, the purpose of this research is to suggest a process(or method) for analyzing economic efficiency of U-City technologies. The process is composed of few works that technology classification, deduction of assessment items, making questionnaire, survey and analysis. By using conjoint analysis, we can calculate few results like values of each technology, marginal rate of substitution between assessment items. Those values are very useful to analysis economic efficiency of U-City technologies. This research has its meaning as attempt to suggest methodology for creating a standard of judgement that can be used to choose more efficient technologies.

Peritonitis is a serious problem in patients undergoing peritoneal dialysis. Rarely pneumatosis intestinalis can occur as a complication of this infectious process. Pneumatosis intestinalis is a potential life threatening condition with a challenging management. The mortality of peritoneal dialysis patients with pneumatosis intestinalis secondary to mesenteric ischemia is almost 100%. We describe a rare case of pneumatosis intestinalis in a peritoneal dialysis patient who developed Staphylococcus aureus peritonitis which was initially treated with appropriate antibiotics. Since initial response to therapy was not achieved, an abdominal computerized tomography was done which revealed a pneumatosis intestinalis. A laparotomy was performed and small bowel necrosis was seen. A segmented resection with ileostomy, jejunostomy was done. Though surgical treatment was performed, the patient died in 2 weeks after admission. Pneumocystitis intestinalis in peritoneal dialysis peritonitis is a uncommon complication which requires prompt evaluation to rule out mesenteric ischemia as it carries a high mortality and its management will be surgical.

발치 및 비발치 치료 전후 악궁 폭경의 변화

전지윤,김수정,강승구,박영국 대한치과교정학회 2007 대한치과교정학회지 Vol.37 No.1

일반적으로 네 개의 소구치 발치를 동반한 교정치료는 비발치 치료에 비하여 치열궁 폭경을 더 좁게 만들어, 미소 시 구각 부위에 어두운 구강 내 공간, 소위 buccal corridor를 형성함으로써 비심미적인 결과를 낳는다는 견해가 있다. 한편 발치 치료는 오히려 하악의 견치간 폭경을 증가시키며, 비발치 치료와 비교하여 악궁 폭경의 변화에 있어 유의한 차이를 보이지 않는다는 상반된 연구결과가 존재한다. 이 연구는 발치 치료와 비발치 치료 시 악궁 폭경의 변화를 관찰하여 실제적으로 발치 치료가 미소 시 협측 분절에 미치는 영향을 규명하고자 시행되었다. 경희대학교 치과병원 교정과에서 치료받은 환자 중 전악에 고정식 장치를 사용하여 네 개의 제1소구치 발치 치료를 받은 30명과 비발치로 치료한 30명의 치료 전후 연구 모형을 비교 분석한 결과 악궁 폭경의 변화는 다음과 같다. 네 개의 제1소구치 발치 치료 시 비발치 치료와 비교하여 상악의 견치간 폭경 변화는 유의한 차이가 없었으나, 하악의 견치간 폭경은 유의하게 더 많이 증가하였다. 구치간 폭경 변화는 상악과 하악 치열궁 모두에서 두 군 간에 유의한 차이가 나타났는데, 발치군에서 구치간 폭경이 감소한 반면에 비발치군에서는 구치간 폭경이 증가하였다. 미소 시 노출되는 악궁 폭경은 비발치군보다 발치군에서 더 크게 나타났으며, 이는 치열궁 폭경의 축소가 발치 치료 시 당연히 예상되는 결과가 아님을 시사한다. Objective: This study was performed to investigate the influences of extraction and nonextraction treatment on smile esthetics by measuring dental arch width changes. Methods: Pretreatment and posttreatment study models of 30 first premolar extraction cases and 30 nonextraction cases were randomly selected to determine whether extraction treatment results in narrow dental arches, and a consequent unaesthetic smile. Arch widths were measured from the cusp tips of the canines and the first molars. Posterior arch widths were also measured at a constant arch depth derived by averaging randomly chosen nonextraction models. Results: The intercanine widths increased significantly in the extraction sample, whereas the intermolar widths decreased significantly. The arch width at a standardized arch depth was significantly wider in the extraction subjects. Conclusion: These results elucidate that constriction in arch width is not a materialized consequence of extraction treatment. It leads to postulate that an esthetically compromising effect from narrow dental arches on smile is hardly anticipated with extraction treatment.

2006년 국내 각 지역으로부터 수집된 재래종옥수수 유전자원을 관행방법에 의해 파종하고 주요특성별로 분포도를 살펴본 결과는 다음과 같다. 1. 수집된 유전자원에 대한 발아율은 대부분 80∼100%이상의 분포를 보였으나, 일부 수집계통에는 30% 미만의 극히 저조한 발아율을 보였다. 2. 수집자원에 대한 초기생육을 살펴보면 극히 생육이 저조한 것이 40% 정도를 보였고, 극히 우수한 자원은 3%미만으로 나타났다. 3. 간장은 대부분이 150∼199cm범위에 55%가 분포하고 있었으나, l00cm이하가 5%, 250cm이상이 8%로 나타나 수집종간에 큰 차이를 보였다. 4. 주당 분얼수는 1개 미만이 40%의 분포를 보였으나, 일부 수집종에서 2 내지 3개의 분얼수를 보이는 계통이 확인되었다. 5. 개화소요일수는 61∼64일의 범위에서 40%, 57∼60일의 범위에서 30%의 분포를 보였으며, 특히 일부 수집종의 경우 55일 이하의 극조생종도 10% 정도의 분포를 보였다. 6. 이삭길이는 대부분 11∼15cm범위에 60%가 포함되어 있으나, 일부계통에서 5cm미만이 2%, 16∼20cm의 이삭길이도 10%가 분포하였다. Germination ratio on the 300 collected genetic resources showed 80 to 100 percentage, but those of some accessions were very low as below 30 percentage. Early growth phase of most of these lines were very poor while some collected lines were very vigor. Range of stem height showed from 150 to 199cm, but that of some accessions showed below 100cm as five percentage and some of them was over 250cm as eight percentage. Number of tillers per plant appeared less one but some collected lines have two to three tillers per plant. In days to tasseling, some accessions showed more four per plant. Ear length of these accession showed above 60 percentage as 11 to 15cm, while that of some collected lines showed over 10 percentage as 16 to 20cm.

This study was designed to identify the effects of foot position on electromyographic (EMG) activity of the quadriceps femoris during maximum voluntary contraction (MVC) in standing. Twenty young adults who had not experienced any knee injuries were recruited. Their Q-angles were within a normal range. They were asked to stand in five different foot positions (40˚externally rotated, 30˚ internally rotated, neutral, 20˚ plantarflexed, and 10˚dorsiflexed foot position). The EMG activities of the vastus lateralis (VL), rectum femoris (RF), and vastus medialis oblique (VMO) were recorded in standing by surface electrodes and normalized by MVC EMG values derived from manual muscle test. The normalized EMG activity levels (%MVC EMG) of muscles in the five foot positions were compared using repeated measures ANOVA. The EMG activity levels of the VL, RF, and VMO were the highest when foot was externally rotated. The EMG activity levels of the VL and RF were significantly different among the foot positions (p<.05). However, EMG activity levels of the VL, RF, VMO, and VMO/VL ratio did not show significant differences in each foot position (p> .05). The results suggest that the quadriceps femoris may be effectively activated by performing MVC a: an externally rotated foot position. Therefore, the externally rotated foot position can be considered as an effective foot position for quadriceps femoris strengthening exercise. Further studies are needed to identify whether there are differences in the effects of foot position on muscle strength after MVC exercise of quadriceps femoris in standing.
