At first, we review a sample size estimation method for log-rank test in survival analysis. Although it is widely used these days, it has a weakness for practical use. We propose a modification method to avoid the weakness.

A 31-year-old pregnant woman with pruritus in pregnancy was described; she presented with a one-week history of generalized pruritus at gestational age 6 weeks without primary skin lesion. She had no dermatologic problem before pregnancy. Her pruritic symptom was not con-trolled with conventional emollient and topical corticosteroids. Broadband Ultraviolet B(UVB) phototherapy successfully improved her pruritus. UVB phototherapy also worked well after recurrence of pruritus at pregnancy 23rd week. We report herein a case of pruritus in pregnancy successfully treated with broadband UVB phototherapy.

The mineral content and width of bone can be determined noninvasively by “bone densitometer”, which measures the absorption by bone of a monoenergetic photon beam that originates in a radioactive source(Iodine-125 at 27.3 Kev). The intensity of the beam transmitted by the bone is measured by a scintillation detector. The bone mineral density is obtained from dividing the bone mineral content by bone width. Since Cameron and Sorenson, in 1963, first described the photon absorptiometry, many investigators have studied this method and applied it clinically. In order to determine the bone density of normal koreans, and compare it with that of fracture risk group, we measured the bone density of the distal one third of the nondominant radius in 152 normal persons(55 male, 97 female), and 54 patients(23 male, 31 female) having the risk of spontaneous fracture from the third to seventh decades. This data were also compared with those of normal Caucasians. The results were as follows. 1. The average bone densities(gm/cm2) of normal men from the third to the seventh decades were 0.773 ±0.055, 0.749 ±0.070, 0.770 ±0.060, 0.797 ±0.053, 0.664 ±0.126, respectively and those of normal women were 0.680 ±0.058, 0.680 ±0.036, 0.674 ±0.052, 0.608 ±0.084, 0.523 ±0.093, respectively. 2. The average bone densitied(gm/cm2) of fracture risk men from the third to seventh decades were 0.647 ±0.072, 0.719 ±0.050, 0.729 ±0.085, 0.699 ±0.064, 0.562 ±0.049, respectively and those of fracture risk women were 0.603 ±0.049, 0.061 ±0.021, 0.326 ±0.034, 0.494 ±0.045, 0.430 ±0.035, respectively. 3. There were statistically significantly differences in the bone densities between the normal population group and the fracture risk group. 4. The average bone densities(gm/cm2) of normal koreans were lower than those of normal Caucasians by 0.115 ±0.023 in male, and 0.091 ±0.005 in female. 5. We belive that bone densitometer is an effective tool in early detection and treatment in metabolic bone deseass including osteoporosis.

Purpose: : This study is a descriptive research study conducted to understand the effects of communication competence, interpersonal relationship, and information literacy competency on problem-solving in the college of nursing. Methods: : This study was conducted from May 16 to May 31, 2022 with 154 students enrolled in the second year of the Department of Nursing in D city. Data collection was measured using a self-report questionnaire that measures communication competence, interpersonal relationships, information literacy ability, and problem-solving ability. Data analysis was performed using the SPSS 23.0 program, descriptive statistics, t-test, ANOVA, Pearson’s correlations, and multiple linear regression. Results: : Communication ability, interpersonal relationship, information utilization ability and problem solving ability were found to have a significant positive correlation. In addition, factors affecting problem-solving ability appeared in the order of information utilization competency, communication ability, and interpersonal relationships, and the explanatory power of these variables for problem-solving ability was 64.9%. Conclusion : Based on the research results of this study, it is necessary to develop and apply an educational program that can improve information utilization ability in order to increase the problem-solving ability of nursing colleges.

Gastrojejunocolic fistula, a rare but serious complication of gastrojejunostomy often results from inadequate resection or incomplete vagotomy during gastric surgery. The most common symptoms include feculent vomiting, chronic diarrhea, and weight loss, and surgical repair is the definitive treatment for this condition. A 51-year-old man presented to our hospital with upper abdominal pain and chronic diarrhea. He had a history of gastric surgery for gastric cancer, 20 years prior at another hospital. Upper endoscopy and abdominal computed tomography confirmed diagnosis of a gastrojejunocolic fistula. In this case report, we present the clinical features and diagnostic approaches for gastrojejunocolic fistulas.
