위니컷은 “나는....이다” 가 “나는...한다”를 앞서야 한다고 하였다. 그렇지 않으면“나는...한 다”는 개인에게 아무 의미도 없다는 것이다. 이것은 쉽게 이해할 수 있다. 우리는 내가 누 구인지 알기 때문에(엄마, 학생, 딸...) 무엇을 한다.(양육, 공부, 효도...) 내가 누구인지 모른 다면 나는 무엇을 할 수가 없다. 나는 아무것도 아니다라는 자기 이미지를 가지고 있다면 나는 아무것도 할 수 없을 것이다.
모의실험을 기반으로 지수형 응답률 보정을 위한 세부 층 결정에 관한 연구

정보적 표본설계 기법을 적용하여 무응답의 영향을 줄이기 위한 연구가 진행되고 있다. 특히 초모집단모형(super population model)에 포함된 오차의 분포가 정규분포를 따르고 응답률이 지수함수를 따를 때 지수형 응답률 정보를 모수추정에 사용함으로써 추정의 정확성이 향상되는 것으로 알려져 있다. 최근 Chung과 Shin (2017)은 정보적 표본설계의 가중치를 구하기 위해 세부 층을 등간격으로 나누는 방법을 고려하였으며 세부 층의 개수가 추정의 정확성에 영향을 주는 것을 확인하였다. 이에 본 연구에서는 주어진 표본 규모에 따른 최적의 세부 층 개수와 최적의 층 경계를 구하기 위해 등간격, 분위수, LH 알고리즘을 이용하여 층을 나누는 방법을 살펴보았으며 모의실험을 통하여 각 방법의 결과를 비교하였다. 또한 다양한 형태의 보조변수 분포를 이용하여 실무에서 사용할 수 있는 세부 층 경계와 세부 층 개수를 정하는 기준을 제안하였다. Research on the application of informative sampling technique has been conducted in order to reduce the influence of non-response. Chung and Shin (Korean Journal of Applied Statistics, 30, 993-1004, 2017) showed that the estimation accuracy improved when using exponential response rate information for the parameter estimation if the distribution of errors included in the super population model follows normal distribution. However this method divides the stratum into equally spaced substrata to obtain the sample weight of the informative sampling technique and shows that the accuracy of the estimation improves as the number of substrata increases. In this study, with the given number of total sample size, the optimal substratum boundary points are calculated using equal space, quantile, and LH algorithm; consequently, the results using those methods are compared through simulation. We also studied the criteria to determine the number of substrata and substratum boundaries that can be used in practice with various types of auxiliary variable distributions.

Background: There has been little data reporting the usefulness of intensivist-performed bedside drainage of pleural effusion via ultrasound (US)-guided pigtail catheter. The objective of this study is to clarify the usefulness and safety of these methods in comparison with radiologist-performed procedures. Methods: Data of patients with pleural effusion treated with US-guided pigtail catheter drainage were analyzed. All procedures were performed from September 2012 to September. 2013 by a well-trained intensivist or radiologist. Results: Pleural effusion was drained in 25 patients in 33 sessions. A radiologist performed 21 sessions, and an intensivist performed 12 sessions. Procedures during mechanical ventilation were performed in 15 (71.4%) patients by a radiologist and in 10 (83.3%) by an intensivist (p = 0.678). The success rate was not significantly different in radiologist- and intensivist-performed procedures, 95.2% (20/21) and 83.3% (10/12), respectively (p = 0.538). The average duration for procedures (including in-hospital transfer) was longer in radiologist-performed cases (p = 0.001). Although the results are limited because of the small population size, aggravation of oxygenation, CO2 retention, and decrease of mean arterial blood pressure were not statistically different in the groups. Pigtail-associated complications including hemothorax, pneumothorax, hepatic perforation, empyema, kink in the catheter, and subcutaneous hematoma were not found. Conclusions: Intensivist-performed bedside drainage of pleural effusion via ultrasound (US)-guided pigtail catheter is useful and safe and may be recommended in some patients in an intensive care unit.

Bone scan (BS) and serum alkaline phosphatase (ALP) concentration are used to detect bone metastasis in malignancy, although whole-body fluoro-D-glucose positron emission tomography computed tomography (FDG PET/CT) is being used increasingly. But BS is still used for the detection of metastatic bone lesion. So we compared the usefulness of PET/CT, BS, and serum ALP in detecting bone metastases in patients with newly diagnosed lung cancer. The medical record database was queried to identify all patients with a new diagnosis of lung cancer between January 2004 and December 2005, who had a PET/CT, BS, and serum ALP before treatment. We retrospectively reviewed all patients’ records and radiological reports. One hundred eighty-two patients met the inclusion criteria. Bone metastases were confirmed in 30 patients. The sensitivity values were 93.3% for PET/CT, 93.3% for BS, 26.7% for serum ALP concentration, and 26.7% for BS complemented with serum ALP concentration. The respective specificity values were 94.1%, 44.1%, 94.1%, and 97.3%. The kappa statistic suggested a poor agreement among the three modalities. FDG PET/CT and BS had similar sensitivity, but PET/CT had better specificity and accuracy than BS. PET/CT is more useful than BS for evaluating bone metastasis. However, in the advanced stage, because of its high specificity, BS complemented with serum ALP is a cost-effective modality to avoid having to use PET/CT.

Pulmonary cavities are caused by bacterial pneumonia, fungal diseases, lung cancer, and tuberculosis (TB). However, in Korea, patients with cavitary lung lesions are generally considered to have pulmonary TB, where the incidence of TB is approximately 70/100,000 per year. We report a case of chronic necrotizing pulmonary aspergillosis that was obscured by multidrug-resistant pulmonary TB. (Tuberc Respir Dis 2007; 63: 368-371)
