본 연구는 김응준(2012)이 Rasch 모형을 적용하여 선행연구에서 개발된 확대된 여가 제약 척도의 심리측정학적 특성 결과를 바탕으로 최적범주를 탐색하는데 목적이 있었다. 이 목적을 달성하기 위해 대학교 410명의 학생들을 대상으로 조사를 실시하고 통계분석하였다. 사용된 척도는 Crawford와 Godbey(1987)에 의해 제시된 여가제약 척도를 지현진과 이철원(2003)이 수정 보완하고, 김응준(2006)에 의하여 타당화 시킨 확대된 여가 제약 척도를 조사도구로 사용하였다. 수거된 자료 중 410명의 자료를 SPSS 23.0프로그램을 이용하여 빈도분석, 기술통계분석을 실시하였다. 최적범주를 탐색하고자 WINSTEPS 3.92 (Linacre, 2016)을 사용하여, 척도수의 적절성, 문항적합도와 문항난이도 등을 산출하였다. 연구목적에 따른 연구결론으로는 첫째, 문항의 반응범주는 문제가 있는 것으로 확인되어 기존 5점 범주 대신 4점 범주로 수정되는 것이 타당하였다. 둘째, 문항적합도를 분석한 결과 22문항은 적합하였다. 셋째, 척도의 응답자 신뢰도가 낮게 확인되어 문항난이도를 고려한 문항순서의 변경이 필요하였다. 넷째, 개인 능력점수와 난이도를 교차하여 비교한 결과, 개인 능력점수 분포와 문항난이도 분포는 적절하였다. The purpose of this study was to investigate the extended leisure constraint questionnaire’s optimal categorization in undergraduate students. To accomplish study purpose, complete enumeration survey and statistical analysis were conducted for 410 students enrolled university. A research tool used in this study was an extended leisure constraint scale developed by Eung-Joon KIM (2012), which was originally from Crawford & Godbey(1987). Total 22 questions were used with 5 point Likert scale and high point stands for higher the leisure constraint. Frequency analysis was conducted with SPSS 23. An assumption to test Rasch Model, which is satisfaction of unidimensionality, is regarded through theoretical aspects, and WINSTEPS 3.92(Linacre, 2016) program is used to test the goodness-of-fit of items. Statistical analysis showed results as follows. First, 4-point rating scale was appropriate for the extended leisure constraint scale. Second, 22 items of the extended leisure constraint scale were suitable in item fitness and item difficulty to undergraduate students. Third, the extended leisure constraint scale was somewhat suitable in person reliability of item separation. Fourth, the person ability score of the extended leisure constraint scale was distributed appropriately.

TiO₂(Rutile)-H₂O 현탁용액의 유동성질에 미치는 농도 및 온도효과

이철우,한상준,김응렬 漢陽大學校 基礎科學硏究所 1990 基礎科學論文集 Vol.9 No.-

TiO₂- water 현탁계의 유동성질을 계의 농도와 온도의 변화에 따라 Couette 형회전 점도계를 이용하여 측정하였으며 Ree-Eyring flow equation으로부터 유도된 dilatant flow equation에 적용하여 고찰하였다. Rutile-water 현탁계는 30%wt 이상의 고농도에서는 thixotropy를 나타내고 25%wt 이하의 농도에서는 dilatancy를 나타내었으며 유동에 대한 활성화 에너지는 약 14Kcal/mol정도였다. 본연구에서는 유동성질간의 전이를 한 물질 내에서 구조의 형성과 파괴가 경쟁적으로 일어난다는 견지에서 고찰하였다. Rheological properties of Rutile-water suspension with various conditions of particle concentrations and temperatures. The rheologicl properties were measured using Couette type rotational viscometer. And we calculated flow parameters with applied to BKHR flow equation. Rutile-water suspension shows dilatancy at lower concentration relatively (at below 28%wt.) but at higher concentration(above 30%wt.) thixotropic flow was observed. And the activation energy for flow was about 14Kcal/mol. In this paper we studied this transition in the view point of competitive rate process between structure formation and deformation in the same material.

Backgrounds and Objectives: Vascular dementia is a group of dementing disoders arising from various stroke syndrome. Among these. subcortical ischemic vascular dementia (SIVD) is regarded as a relatively distinct clinical entity. However, MRI patterns of SIVD are not homogenous. In some patients, lacunes are dominant, and in others, subcortical white matter changes are. This study was designed to compare risk factor profiles between SIVD with and without multiple lacunes. Methods: We divided 47 subjects (22 males, mean age. 68 years) recruited from VADAPET (Multicenter Trial For Evaluation Of The Changes In the PET Images Of Subcortical Vascular Dementia Patient) study into two groups one with more than 5 lacunes in deep gray matter (lacune group) and the other with 5 or less(non-lacune group) Clinical characteristics and laboratory findings of two groups were compared. Results: Nineteen of 47 patients (40%) belonged to the lacune group. The lacune and non-lacune groups d d not differ in the following variables: age, hypertension, diabetes mellitus, hyperlipidemia heart disease, history of stroke or TIA, history of trauma or major surgery, family history of hypertension stroke, or dementia, age at diagnosis of dementia, body mass index, white blood cell count, ESR, CRP, fibrinogen, hemoglobin A1C, total cholesterol. LDL cholesterol creatinine, proteinuria, glucosuria, and microhematuria. However, male sex, smoking alcohol. hemoglobin, and HDL cholesterol were possibly associated more with lacune group SIVD than with non-lacune group (p<0 1) Multivariate analyses revealed that smoking, hemoglobin, and HDL cholesterol were independent predictors of SIVD with multiple lacunes Conclusion: Our study suggests that SIVD with multiple lacunes may be significantly different in smoking habits hemoglobin, and HDL cholesterol from SIVD without multiple lacunes.

Locally recurrent rectal cancer is a difficult clinical problem. Local recurrence following treatment for rectal cancer is a major cause of morbidity and mortality. The reported range of local recurrence rates following surgical treatment for rectal cancer has varied from 4% to 50%. We retrospectively reviewed the charts of 142 rectal cancer patients from January 1991 to December 1999. Analysis of patients factors included age, gender, type of surgery, and adjuvant therapy. Tumors were assessed for level, stage, and grade. Local recurrence and distant metastases were also documented. Variables influencing local recurrence in this group were identified and disease-free survival is determined. Of the 142 patients(74 males, 68 females; mean age 62.6 years), 137 consecutive patients operated on for rectal cancer and followed up to December 2000 (range 23-118months) were analyzed. Local recurrence rate was 18.3%. Age and sex of patients, type of surgery, location of tumor in the rectum, size, morphology and grading of the tumor were all unrelated to the event under investigation. At Cox regression, the Dukes stage and the postoperative radiotherapy were the only independent prognostic factors for local recurrence, and Dukes stage (Hazard ratio=2.89, p<0.001) and local recurrence (Hazard ratio=3.31, p<0.01) were the only independent factors associated with improved survival.

<P><B>Abstract</B></P><P>Portal vein embolization (PVE) is increasingly performed worldwide to reduce the possibility of liver failure after extended hepatectomy, by inducing future liver remnant (FLR) hypertrophy and atrophy of the liver planned for resection. The procedure is known to be very safe and to have few procedure-related complications.</P><P>In this study, we described 2 elderly patients with Bismuth–Corlette type IV Klatskin tumor who underwent right trisectional PVE involving the embolization of the right portal vein, the left medial sectional portal branch, and caudate portal vein. Within 1 week after PVE, patients went into sepsis combined with bile leak and died within 1 month.</P><P>Sepsis can cause acute liver failure in patients with chronic liver disease. In this study, the common patient characteristics other than sepsis, that is, trisectional PVE; chronic alcoholism; aged >65 years; heart-related comorbidity; and elevated serum total bilirubin (TB) level (7.0 mg/dL) at the time of the PVE procedure in 1 patient, and concurrent biliary procedure, that is, percutaneous transhepatic biliary drainage in the other patient might have affected the outcomes of PVE.</P><P>These cases highlight that PVE is not a safe procedure. Care should be taken to minimize the occurrence of infectious events because sepsis following PVE can cause acute liver failure. Additionally, prior to performing PVE, the extent of PVE, chronic alcohol consumption, age, comorbidity, long-lasting jaundice, concurrent biliary procedure, etc. should be considered for patient safety.</P>

A study on the electrorefining of an impure uranium containing zirconium and neodymium at 500℃ by KCl-LiCl fused salt electrolysis was performed. The reduction potentials of uranium and neodymium were 0.12V and 0.64V.(vs. Ag/AgCl electrode), respectively. When a 1wt.%Nd of uranium was added as an impurity, 0.001wt% Nd was deposited onto the cathode below 0.5V after electrolysis. When a 10.5wt.% Zr of uranium was added to liquid cadmium anode as an impurity, zirconium was evaporated as ZrCl₄, at 500℃ during electrolysis, and consequently uranium was deposited onto the cathode as a purity of 99.98wt.% U. The morphology of purified uranium was appeared as dendritic structure. The activity coefficient of metallic neodymium for the displacement reaction of UCl₃+Nd_(cd)=NdCl₃+U_(cd), was calculated to be 3.67×10^(-10) at 500℃.

The Value of Postoperative Serum Carcinoembryonic Antigen and Carbohydrate Antigen 19-9 Levels for the Early Detection of Gastric Cancer Recurrence after Curative Resection

Lee, Eung-Chang,Yang, Jun-Young,Lee, Kyung-Goo,Oh, Seung-Young,Suh, Yun-Suhk,Kong, Seong-Ho,Yang, Han-Kwang,Lee, Hyuk-Joon The Korean Gastric Cancer Association 2014 Journal of gastric cancer Vol.14 No.4

Purpose: This study aimed to evaluate the value of serum carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA19-9) levels to detect gastric cancer recurrence. Materials and Methods: We retrospectively reviewed 154 patients who developed recurrence within 2 years after curative gastric cancer surgery and analyzed the relationship between postoperative CEA and CA19-9 levels and recurrence. We readjusted the cut-off values to improve the detection of recurrence. Subgroup analysis according to clinicopathologic variables was performed to further investigate the relationship between recurrence and CEA and CA19-9 levels. Results: The sensitivity and specificity for elevated CEA levels to detect recurrence were 40.6% and 89.5%, respectively, and those for CA19-9 were 34.2% and 93.6%, respectively. The sensitivity and specificity for elevation of either tumor marker were 54.3% and 84.0%, respectively; those for elevation of both tumor markers were 19.2% and 98.4%, respectively. By readjusting the cut-off values from 5.0 ng/ml to 5.2 ng/ml for CEA and from 37.00 U/ml to 30.0 U/ml for CA19-9, the sensitivity was increased from 34.2% to 40.2% for CA19-9, while there was no increase in sensitivity for CEA. In subgroup analysis, the sensitivity of CEA was higher in patients with elevated preoperative CEA levels than in patients with normal preoperative CEA levels (86.7% versus 33.7%; P<0.001). Furthermore, the sensitivity of CA19-9 was higher in patients with elevated preoperative CA19-9 levels than in patients with normal preoperative CA19-9 levels (82.61% versus 26.83%; P<0.001). Conclusions: CEA and/or CA19-9 measurement with the readjusted cut-off values allows for more effective detection of gastric cancer recurrence.
