본 연구의 목적은 미술요소 중심의 협동미술활동이 유아의 친사회성, 언어능력, 그리기 표상능력에 미치는 효과를 검증하는 데 있다. 연구대상은 만 5세 유아 50명이며, 평균 원령은 71.04개월이었다. 실험집단 유아들은 미술요소 중심의 협동미술 활동에 참여하였고, 비교집단 유아들은 표현중심의 협동미술 활동을 실시하였다. 연구도구로는 유아의 친사회성 능력 측정을 위하여, McGinnis와 Goldstein의 ‘사회적 기술상황 검사도구’를 번안하고 수정하여 사용하였고, 유아의 언어능력 측정은 서울장애인복지관이 개발한 ‘구문이해력검사’, 그리기 표상능력은 지성애의 ‘그리기 표상능력 측정척도’를 사용하였다. 수집된 자료는 SPSS18.0 프로그램을 사용하여 독립표본 t검증과 공변량분석을 사용하여 집단 간 차이를 분석하였다. 연구결과 실험집단이 비교집단 보다 친사회성, 언어능력, 그리기 표상능력에서 점수가 유의하게 높은 것으로 나타나 본 연구에서 개발한 소집단 종이접기 활동이 유아의 친사회성, 언어능력, 그리기표상능력 증진에 긍정적인 효과가 있는 것으로 밝혀졌다. The purpose of this study was to construct the art elements-centered cooperative art activity and to analyze the effects of the art elements-centered cooperative art activity on young children's pro-sociability, language ability, and drawing representation ability. The subjects used in this study were fifty 5 year-old student who attended S kindergarden in G city. Mean age of the subjects was 71.04 months. The translated and modified version of ‘Social Situation Measurement’ devised by McGinnis and Goldstein(1990), the ‘Understanding about Syntactic Meaning Scale’ developed and standardized by Seoul Community Rehabilitation Center(2009), and the ‘Drawing representation Ability Scale’ made by Chi, Sung-Ae(2001) were used to measure pro-sociability, language ability, and drawing representation ability of young children respectively. The study also used Independent t-test and ANCOVA to analyze the data. It was revealed that the scores of the experimental group in the pro-sociability, language ability, and drawing representation ability were significantly higher than the scores of the comparative group. In conclusion, the results of this study suggest that the Art Elements-Centered Cooperative Art Activity is effective in promting youngchildren's pro-sociability, language ability, and drawing representation ability.

1993년부터 2015년까지 관측된 제주도 지하수 장기모니터링 관측정(N = 4,835)에서 수집된 지하수 수질자료(N = 21,568)를 기반으로 질산성질소의 시공간적 변동 특성을 평가하였다. 제주도 지하수의 질산성질소 농도의 중앙값은 2.5 mg/L로서 다른 국가나 대륙의 조사 결과에 비해 다소 높거나 유사한 것으로 나타났다. 또한 지하수 용도, 행정구역 및 고도 별로 유의한 차이를 보였다. 특히, 산간 지역에 비해 저지대 해안가에 위치한 농업 및 주거지역에서 농도가 높음을 확인하였다. Mann-Kendall 및 Sen’s slope 분석을 활용한 질산성질소 농도의 추세 분석 결과, 하류 저지 대에 비해 중산간지역에서의 질산성질소 농도 증가 경향이 뚜렷하였다. 제주도 내 토지 피복의 시계열 변화 특성과 결부 지어 보면, 중산간지역의 오염 증가 추세는 농업지역의 확장 등 인위적 활동 증가에 기인한 결과로 판단된다. 반면,기지정된 지하수자원특별관리구역에서는 전반적으로 질산성질소 농도의 감소 경향이 나타났는데, 이는 지하수 관리 측면에서 수질관리를 위한 적극적인 정책이 유효함을 시사한다. 본 연구에서는 제주도 지하수의 질산성질소 오염관리를 위한 적정 방안을 제안한다. The spatio-temporal variations of nitrate concentrations in groundwater of Jeju Island were evaluated by an analysis of time series groundwater quality data (N = 21,568) that were collected from regional groundwater monitoring (number of wells = 4,835) for up to 20 years between 1993 and 2015. The median concentration of NO 3 -N is 2.5 mg/L, which is slightly higher than those reported from regional surveys in other countries. Nitrate concentrations of groundwater in wells tend to significantly vary according to different water usage (of the well), administrative districts, and topographic elevations: nitrate level is higher in low-lying agricultural and residential areas than those in high mountainous areas. The Mann-Kendall trend test and Sen’s slope analysis show that nitrate concentration in mid-mountainous areas tends to increase, possibly due to the expansion of agricultural areas toward highland. On the other hand, nitrate concentrations in the Specially Designated Groundwater Quality Protection Zones show the temporally decreasing trend, which implies the efficiency of groundwater management actions in Jeju. Proper measures for sustainable groundwater quality management are suggested in this study.

Background: The long-term benefits of interferon (IFN) -based therapy on preventing cirrhosis and hepatocellular carcinoma (HCC) in chronic hepatitis C (CHC) patients have not been well investigated in Korea. Our study aimed to assess the incidence of cirrhosis and HCC and to identify the risk factors associated with disease progression in CHC patients during 10 years. Methods: A total of 280 patients who were registered as CHC between 2001 and 2010 were retrospectively reviewed. Results: Among 280 subjects, 222 patients (79.3%) received antiviral treatment. Cirrhosis already existed in 37 patients (13.2%) at baseline. Of the 243 patients who had not cirrhosis initially, 17 (7.0%) developed cirrhosis. The 10-year cumulative incidence of cirrhosis was significantly lower among patients with antiviral therapy (8.2%) than those without antiviral therapy (43.0%) (P<0.001). Among patients with antiviral therapy, sustained virologic responders (0.6%) had significantly lower incidence of cirrhosis than non-responders (16.7%) (P<0.001). Cox proportional hazards regression showed sustained virologic responders was the only significant independent factor for reducing risk of cirrhosis development (hazard ratio=0.086, P=0.029). During the follow-up period, 17 patients (6.1%) developed HCC. All these patients had pre-existing cirrhosis (11 patients) or newly developed cirrhosis (6 patients) at the time of HCC diagnosis. The 10-year cumulative incidence of HCC was higher among patients without antiviral therapy (42.7%) than those with antiviral therapy (6.1%) (P<0.001). But, multivariate analysis showed underlying cirrhosis was the only independent risk factor associated with HCC development (hazard ratio=7.702, P=0.010). Conclusions: A sustained virologic response (SVR) secondary to IFN-based therapy could reduce cirrhosis development CHC patients. But, the strongest predictor for the development of HCC was underlying cirrhosis rather than antiviral therapy or SVR.

Objective : Surgical site infection is the most detrimental complication following cranioplasty. In other surgical fields, intrawound vancomycin powder application has been introduced to prevent surgical site infection and is widely used based on results in multiple studies. This study evaluated the effect of intrawound vancomycin powder in cranioplasty compared with the conventional method without topical antibiotics. Methods : This retrospective study included 580 patients with skull defects who underwent cranioplasty between August 1, 1998 and December 31, 2021. The conventional method was used in 475 (81.9%; conventional group) and vancomycin powder (1 g) was applied on the dura mater and bone flap in 105 patients (18.1%; vancomycin powder group). Surgical site infection was defined as infection of the incision, organ, or space that occurred after cranioplasty. Surgical site infection within 1-year surveillance period was compared between the conventional and vancomycin powder groups with logistic regression analysis. Penalized likelihood estimation method was used in logistic regression to deal with zero events. All local and systemic adverse events associated with topical vancomycin application were also evaluated. Results : Surgical site infection occurred in 31 patients (5.3%) and all were observed in the conventional group. The median time between cranioplasty and detection of surgical site infection was 13 days (range, 4–333). Staphylococci were the most common organisms and identified in 25 (80.6%) of 31 cases with surgical site infections. The surgical site infection rate in the vancomycin powder group (0/105, 0.0%) was significantly lower than that in the conventional group (31/475, 6.5%; crude odds ratio [OR], 0.067; 95% confidence interval [CI], 0.006–0.762; adjusted OR, 0.068; 95% CI, 0.006–0.731; p=0.026). No adverse events associated with intrawound vancomycin powder were observed during the follow-up. Conclusion : Intrawound vancomycin powder effectively prevented surgical site infections following cranioplasty without local or systemic adverse events. Our results suggest that intrawound vancomycin powder is an effective and safe strategy for patients undergoing cranioplasty.

The reported incidence of vesicovaginal fistula following hysterectomy is about 0.2%. Standard management of vesicovaginal fistula requires 3-6month interval from injury to repair to ensure complete resolution of necrosis and inflammation. In 1942, Latzko developed a technique whereby posthysterectomy vesicovaginal fistulas were treated through a purely vaginal approach of which result was excellent. We would like to present the simple and effective Latzko procedure for posthysterectomy vesicovaginal fistula within 1month after hysterectomy. Case 1: A 38-year-old woman, hysterectomy for CIN III, a urinary leakage in 11days after hysterectomy. Latzko operation was performed after 31days postoperatively. Foley catheter was kept for 14days after surgery. Case 2: A 42-year-old woman, hysterectomy for adenomyosis, a urinary leakage in 10days after hysterectomy. Latzko operation was performed after 26days postoperatively. Foley catheter was kept for 10days after surgery. Case 3: A 52-year-old woman, hysterectomy for myoma, a urinary leakage in 12days after hysterectomy. Latzko operation was performed after 28days postoperatively. Foley catheter was kept for 13days after surgery. Case 4: A 46-year-old woman, a hysterectomy for myoma, a urinary leakage in 14days after hysterectomy. Latzko operation was performed after 25days postoperatively. Foley catheter was kept for 15days after surgery. Conclusion: Latzko operation has advantages of short operating time, minimal blood loss, and low postoperative morbidity while being a simple and minimally invasive procedure.
