An empirical formula for determining water content as functions of uranium concentration and nitric acid normalities in uranyl nitrate solutions has been derived from a least-squares analysis of experimental data, i.e., uranium concentration, nitric acid normalities and solution densities for a large number of UO$_2$(NO$_3$)$_2$ solutions. The formula derived is Q=1-0.3628C-0.0327H$^{+}$ where Q, C, and H$^{+}$ stand for water content (g/cc), uranium concentration (g/cc), ana nitric acid normality, respectively. Atom number densities and nuclear criticality for hypothetical uranyl nitrate solutions have been calculated by using the empirical formula, ana compared with the results obtained on the basis of uranium concentration, nitric acid normality, and solution density. The empirical formula derived in this study seems to be useful in uranium concentrations ranging from 0.295g/cc down to 0.004g/cc and nitric acid normality from 5.06 to 1.00..00.

Purpose: To determine effects of family conflict mitigation documentary programs on conflicts, autonomic nerve activation (ANA), and happiness of elderly in long-term care hospitals. Methods: This study used a non-equivalent control group with a pretest-posttest design. It was conducted on 39 elderly patients (19 in the experimental group and 20 in the control group) in long-term care hospitals. The experimental group (n=19) received family conflict mitigation documentary programs. The family conflict mitigation documentary programs consisted of four sessions (40-50 minutes per session). These programs were implemented in small groups, with each group having five elderly. Data were analyzed by sing the conflict checklist, the Oxford Happiness Questionnaire, Chi-square test with Fisher's exact test, independent t-test, paired t-test, and repeated measure ANOVA using the SPSS/WIN 21.0 program. Results: The participants in the experimental group showed significantly decreased scores of conflict (t=-2.31, p=.028) and the value of sympathetic nervous system activity (t=8.36, p=.007) compared with those of the control group. The participants in the experimental group showed significantly increased the value of parasympathetic nervous system activity (t=-2.91, p=.008) and scores of happiness (t=5.46, p<.001). Conclusion: The family conflict mitigation documentary programs on conflicts, ANA, and happiness of the elderly in long-term care hospitals are effective intervention programs for mitigating conflicts between elderlies and their families and for improving happiness of the elderly in long-term care hospitals.

Matrix Assisted Laser Desorption ionization Time of Flight (MALDI-TOF) was used for enzymes identification related to B -1,3-glucan synthesis. Agrobacterium sp. ATCC31750 was cultivated with two stage Continuous Stirrer Tank Reactor (CSTR) and the cells were harvested and their protein profiles were analysed by two dimensional electrophoresis. The specific enzyme spot was treated with trypsin and ana lysed by MALDI-TOF to get peptide molecular weight. The peptide molecular weights were matched with Agrobacterium tumefacience's Data Base from the matrix science site, then could identify the avaliable key enzymes. In this study, we identified key metabolite of synthesis of beta-1,3-glucan, such as glucose-6-phosphate isomerase, phosphoglucomutase, B-1,3-glucan synthase and glucokinase, and we also identified uracil phosphoribocyl transferase and Ribosome recycling factor also.

There is a symbolic term which has realized custom of an era and has eome into fashion since the middle of 1920's. That is Garconne. This paper studied the image and costume of Garconne expressed in literary works, the form of art made it to come into being, and costume of a group of women played a role of pioneers of Garconne. Garconne attempted simple, casual, and mannish costume instead of usual elegance. It was the boiysh style($\`{a}$, la Garconne) which did not stress on the bust and waist like chanel suits used wool jersey by a designer, Chanel ana short skirts of low waist line. They got short haircut and wore low heel shoes. Garconne meant women who were free of convention, were familiar with love a d profession, and lived for themselves in the same manner of young men. They yieled new mode of 1920's. Though their lives were only a period, they manifested the symbol of the period though their figure and designation was not disappeared at the age but was settled as a mark of fixed image. There were several reasons why the Garconne was born. Rapid changes in politics, economics, and society in Europe were occurred from the First World War to 1920 and the trend of custom and art was a turning point. Especially, the entry of women into the society and the mode of Art Deco influenced it directly. The role of a pioneer of Garconne was appeared from the French Revolution. As Merveilleuse, Lionne, and Bloomers wore peculiar clothings ana had life style being irrelevant to tradition, they were talked about. They informed in advance the appearance of new women who were different from romantic ladies and were more modern and active. The pioneer design of Paul Poiret which were over whelming throughout a period and functional design of Chanel were increasingly accelerated.

Background: Tuberculosis (TB)-related stigma has been well-documented. Since the emergence of the coronavirus disease 2019 (COVID-19), different organizations have been alerted to the fact that stigma could arise again. Due to stigma's negative effects, this qualitative study aimed to explore the stigma felt by patients by evaluating the following: COVID-19 stigma and its temporal progression through the pandemic; stigma perceived by different patients with TB before and during COVID-19 pandemic; and difference perceived by individuals who contracted both diseases. Methods: A semi-structured interview was developed according to the available literature on the theme. It was performed individually in 2022 upon receiving signed informed consent. Participants were recruited with a purposive sampling approach by searching medical records. Those who currently or previously had pulmonary TB and/or COVID-19 were included. Data were subjected to thematic analysis. Results: Nine patients were interviewed, including six (66.7%) females. The median age of patients was 51±14.7 years. Four participants (44.4%) had completed high school and four (44.4%) were never smokers. Three had both TB and COVID-19. Four only had TB and two only had COVID-19. Interviews identified eight main themes: knowledge and beliefs, with several misconceptions identified; attitudes towards the disease, varying from social support to exclusion; knowledge and education, assumed as of extreme importance; internalized stigma, with self-rejection; experienced stigma, with discrimination episodes; anticipated stigma, modifying actions for avoiding stigma; perceived stigma, with judgment by others prevailed; and temporal evolution of stigma. Conclusion: Individuals expressed strong stigma for both diseases. De-stigmatization of respiratory infectious diseases is crucial for limiting stigma's negative impact.

Objectives: This study tested the hypothesis that cryotherapy duration influences lipopolysaccharide (LPS)-induced inflammation in a rat model. Materials and Methods: Six Wistar rats (Rattus norvegicus albinus) were used. Five sites were selected per animal and divided into 5 groups: a negative control group (NC), 2 positive control groups (PC1 and PC2), and 2 experimental groups (E1 and E2). Cryotherapy was applied for 1 minute (E1) or 5 minutes (E2). An acute inflammatory response was induced in the PC and E groups via subcutaneous administration of 0.5 mL/kg. In the PC2 group, a catheter was inserted without additional treatment. For the E1 and E2 groups, 2.5℃ saline solution was administered through the implanted catheters for 1 and 5 minutes, respectively. The rats were sacrificed, and samples were obtained and processed for histological analysis, specifically examining the presence of polymorphonuclear neutrophils and hemorrhage. The χ² test was used to compare the presence of acute inflammation across groups. Dependent variables were compared using the linear-by-linear association test. Results: Inflammation and hemorrhage varied significantly among the groups (p = 0.001). A significantly higher degree of acute inflammation was detected (p = 0.0002) in the PC and E1 samples than in the E2 group, in which cryotherapy was administered for 5 minutes. The PC and E1 groups also exhibited significantly greater numbers of neutrophils (p = 0.007), which were essentially absent in both the NC and E2 groups. Conclusions: Cryotherapy administration for 5 minutes reduced the acute inflammation associated with LPS and catheter implantation.

Soybean lipoxyeenase isozymes were isolated from acetone-defatted soybean seeds(Glycine max [L.] Merr. variety AmSoy) by ammonium sulfate fractionation, eel filtration, and ion exchange chromatoeraphy. The final preparation of lipoxygenase-1 and -2 obtained was 19- and 32-fold purified, respectively, to the crude extract. But a considerable loss of total enzyme activity occurred during purification. On 7% polyacrylamide gel electrophosis at pH 9.0, employing lipoxigenase specific staining technique, lipoxyeenase-1, -2, and -3 showed distinctive Rf values of 0.38, 0.29, and 0.33, respectively.

On May 16, 2014 the Supreme Court of Korea rendered its decision with respect to litigation filed by All Nippon Airways Co., Ltd. ("ANA") for revocation of an order of correction and payment of a penalty imposed by the Korea Fair Trade Commission ("KFTC"). On or around September 2002, ANA and various airlines operating air cargo service from Japan to Korea were allegedly to have agree to introduce of fuel surcharge into their rates on cargo fares in an attempt to recoup falling profits from rising of oil price. As this hard core cartel was per se prohibited under Korean competition law (The Monopoly Regulation And Fair Trade Act), KFTC began an investigation and consequently with fruitful results imposed an amount of penalty and issued an order of prohibition. ANA protested against this imposition by filing suit against KFTC under the reasons that (1) their agreement was simply pursuant to the relevant laws and regulations including Air Transport Agreement between Korea and Japan, (2) there was an administrative guidance from Japanese government to allow this agreement, (3) extraterritorial application of Korean competition law to the agreement in this matter was improper as it was made within Japan and targeted only for the shipment from Japan to Korea: accordingly there is not a direct and serious effect between the agreement and any result of anti-competitive. This article aims to review ANA's allegation and the judgement delivered by Korean court under some issues respectively; (1) whether there is an effectively actual anti-competitive cartel between airlines including plaintiff, (2) whether filed rate doctrine is reasonable and applicable in this case for precluding wrongfulness, (3) what is the reasonable limitation of boundaries in extraterritorial application of Korean competition law. Additionally, this article also suggests to concern particular features of air transport business as an regulated industry in judging the unfair restrain on competition.
