경부 염증을 주 증상으로 하는 이상와 누공의 치료로써, 전통적으로 외과적 절제술이 주로 시행되었으나, 근래에 들어서는 수술 관련 위험성이 적은 삼염화아세트산 소작술이 선호되고 있다. 본원에서, 2004년 5월부터 2013년 3월까지 컷 다운 튜브를 이용한 삼염화아세트산 소작술을 통해 이상와 누공을 치료한 5명 환자의 증례를 보고한다. 이전까지의 삼염화아세트산 소작술에서, 여러 도구를 이용해 누공의 입구만을 막는 시도를 했던 것과는 달리, 본 증례에서는, 컷 다운 튜브를 이용해 20~50%의 삼염화아세트산을 누공로에 주입함으로써, 이상와 누공 전장을 폐쇄하고자 하였다. 3명의 환자에서는 추적 관찰 중 재발 소견 없었으며, 2명의 환자는 추적 관찰 기간 중 재발하여 삼염화아세트산 소작술을 재시행하였다. 모든 증례에서 부작용 및 합병증은 발생하지 않았다.

대다수의 견관절 전방 불안정성에서 관절와에 골 소실이 큰 경우는 Bankart 복원술을 튼튼하게 하였을지라도 상완골두를 지탱할 관절 궁이 감소되어 골에 의한 버팀이 줄어들므로 Bankart 복원이 실패할 가능성이 높다. 따라서 관절와 결손이나 상완골 두 결손이 큰 경우 정확한 측정으로 결손의 범위를 파악하여야 하며, 관절와 결손이 25% 이상이거나 상완 골 두 결손이 30% 이상인 경우 추가적인 수술적 처치가 요하여 최근 보고되고 있는 Latarjet 술식이나 관절경적 Remplissage 술식을 시행하는 것이 바람직하다.

세계의 이상기상은 조만간 우리에게 재난으로 다가올 것이고 우리나라는 이를 사전에 대비한 체계를 갖추어야 한다. 따라서 실제 이상기상으로 야기될 수 있는 재난의 유형과 그 심각성을 중심으로 향후 우리나라가 대처하기 위해 지금부터 준비하여야 하는 이상기상 관련 안전관리의 필요성을 논의하고자 한다.

This study aimed to assess the health status based on the anthropometric and biochemical measurements of middle-aged and elderly people living in Andong area. The subjects were 1,384 people (532 males, 852 females) aged 50 years and over (average 62.7 years). The mean anthropometric values for males and females were heights of 163.7 and 151.5 cm; weights 63.6 and 57.3 kg; body mass index (BMI) 23.6 and $24.9kg/m^2$; body fat 21.8 and 31.8%, respectively. Height and weight were lower, however, waist circumference (in female) and BMI were higher than those of the 2001 National Health and Nutrition Survey (NHNS). Obesity incidences of male and female subjects were 28.7% and 47.3% by BMI; 25.8% and 50.8% by % body fat; and 15.6% and 80.9% by waist circumference, respectively. Also, abdominal adiposity was very severe in female subjects of 50s. The mean biochemical measurements of male and female were as follows: systolic and diastolic blood pressure 136.9, 83.8 mmHg and 133.6, 82.5 mmHg; hemoglobin (Hb) 14.3 and 13.0 g/dL; hematocrit (Ht) 44.7 and 39.8%; blood albumin 4.15 and 4.04 g/dL; total-cholesterol 170.0 and 183.1 mg/dL; HDL-cholesterol 43.6 and 42.7 mg/dL; fasting blood glucose 96.7 and 93.0 mg/dL, respectively. Also, the prevalence of biochemically abnormal subjects according to each cut-off point of biochemical measurements were analyzed. The results for male and female were; hypertension 58.0% and 47.2%; iron deficient anemia 19.3% and 20.6% by Hb, 7.2% and 11.9% by Ht; hypoalbuminemia 9.8% and 11.7%; diabetes 12.0% and 10.2%; hypercholesterolemia 19.5% and 30.5%, respectively. From those results we found that hypoalbuminemia, hypertension and hypercholesterolemia were prevalent, and obesity in females of 50s, iron-deficient anemia and diabetes in males of 70 years and over were significant health problems in this area. Therefore, it seems to be necessary to examine their health status periodically and provide the appropriate health and nutrition education program, which includes low sodium intake, balanced diet, exercise and weight control, to prevent the occurrence of chronic diseases.

This study purports to depict the generational topography of welfare attitudes of Korean people. Three generational groups are made for analytical purpose, 'between 20-39 age group', 'between 40-59 age group', and '60 and older'. Two major statistical techniques are used, the analysis of variance and correspondence analysis. The analysis of variance shows that the respondents' attitudes upon 'social services target(universal vs selective)', 'education', 'housing', 'child-care', 'youth support', and 'employment' varies significantly by age groups. Correspondence analysis also shows that 'between 20-39 age group' is located with proximity with 'child-care', 'employment', and 'housing', while '60 and older' is located with 'poverty' and 'old age life care'. Clearly this study shows that there is generational difference on welfare consciousness in many areas of social policy. Overall, the results show that significant generational differences with regard to welfare attitudes clearly exist in current Korean society.

The relationship between lipoprotein(a) and dyslipidemia is not clear. This study was therefore undertaken to investigate the relationship between lipoprotein(a) and dyslipidemia in elderly patients over 60 years. From 2014 to 2020, a total of 2,580 adults aged 60 years or older (73.31±7.24 years, 1,954 males) were enrolled in the study. The patients had checked into a general hospital, and data were obtained for lipoprotein(a), LDL-C, TG, HDL-C, hs-CRP, HbA1c, sex, age, BMI, dyslipidemia diagnosis, and use of lipid-lowering agents. BMI and HbA1c showed no correlation with lipoprotein(a), but hs-CRP (r=0.138), LDL-C (r=0.097), HDL-C (r=-0.089), TG (r=-0.073), and age (r=0.072) were significantly correlated to lipoprotein(a). The partial correlation between lipoprotein(a) and LDL-C, which was adjusted for variables, was significant only in the male gender (r=0.158, P<0.001). As the odds ratio of the 4^th quartile of lipoprotein(a) (OR=1.376, 95% CI=1.038~1.822) for dyslipidemia was found to be significant in this study when the level of LDL-C, the primary target, could not be reduced even by taking lipid-lowering drugs, we propose that lipoprotein(a) should also be included among the several factors considered as secondary targets. Our results indicate that studies on various lipid factors considering the sex, age, types and use of lipid-lowering agents, are warranted.

견관절 전방 불안정성에서 관절와 및 상완골 결손이 동반된 경우 적절한 진단과 치료는 치료 결과에 직접적인 영향을 주므로 중요하다. 견관절 불안정성은 정적 및 동적 안정화 구조물의 손상으로 기인하며, 상완골 두감입 골절(Hill-Sachs 병변), 관절와 골절이나 전하방 관절와 가장자리의 소실 등 정상적인 관절의 해부학 구조물을 훼손시키는 골성 이상 소견이 동반되면 경우에 따라 견관절 불안정성에 영향을 끼칠 수 있다. 본 강좌에서는 견관절 전방 불안정성에서 동반된 관절와 및 상완골의 골 결손에 대하여 논하고자 한다.

리튬이온 2차전지(Lithium ion battery, LIB)는 기존에 사용되던 전지에 비해 에너지 밀도가 높고 충방전 사이클이 우수하다. 이 때문에 휴대전화와 노트북 등에 수요가 급속하게 증가하고 있으며 1995년 LIB의 생산량은 4천만 개에서 2004년에는 약 8억 개로 20배 이상 증가하였다. 이에 따라 폐LIB도 급속하게 증가하게 되어 전국적인 재활용 시스템의 확보가 필요한 실정이다. 본 연구에서는 폐LIB에 함유되어 있는 유가금속 중에서 리튬코발트옥사이드(이하 $LiCoO_2$)를 회수하기 위하여 분쇄기(orient vertical cutting mill)와 진동 Screen을 사용하여 유기분리막, 금속류(Aluminium foil, Copper foil, case 등) 그리고 전극물질(lithium cobalt oxide와 graphite 등의 혼합 분말)로 분리하였다. 전극물질에서 $LiCoO_2$와 graphite 분리를 위한 전처리 단계로서 $500^{\circ}C$ 정도의 열처리를 하여 $LiCoO_2$의 표면 성질을 변화시켜 부유선별에 의해 $LiCoO_2$와 graphite의 분리가 가능하도록 하였다. 부유선별 실험 결과 93% 이상의 순도를 가지는 $LiCoO_2$를 92% 이상 회수할 수 있었다.

In this study, we explored the application of Wasabi addition to baechu kimchi with regard to quality improvement, by reviewing the optimum Wasabi level and its effects on the product physicochemical characteristics during fermentation. The final weight percentages of Wasabi in the baechu kimchi were adjusted to 0, 2, 3, 4, and 5% per weight of baechu, respectively, and the samples were fermented for 35 days at $10^{\circ}C$. Following fermentation, the treatments over 3% Wasabi contained the highest pH and lowest total acidity values. Total vitamin C and reducing sugar content increased initially, up to certain fermentation times depending on the level of Wasabi contents within the treatments over 3% Wasabi, and decreased afterwards. The water soluble pectin content increased as the fermentation period increased; however, it decreased with increasing levels of Wasabi. In conclusion, the optimum levels of added Wasabi in the baechu kimchi were 3% and 5% per weight of baechu, to have a fermentation-retarding effect on the product.

We describe a case of venous malformation of pyriform sinus in 63 year-old patient, discovered incidentally. Venous malformation are the most common vascular malformations to arise in the head and neck. However venous malformation of the hypopharynx in the adult papulation are rare. The author performed successfully ethanol sclerotherapy for venous malformation of pyriform sinus, so we present the case with a review of the related literatures.
