Paratesticular liposarcoma is a very rare tumor that is typically reported as isolated cases of or as components of larger studies of liposarcomas. Image findings are similar to those of other anatomic sites, but in less-common sites, their appearance may be less familiar, and they may be mistaken for other pathologies. In addition, atypical image findings of liposarcoma make diagnosis more difficult. Herein, we report on the case of a 45-year-old male patient who presented with a painless, palpable mass in the right scrotum. The patient was diagnosed with paratesticular liposarcoma by excisional biopsy.

Objective : The thyrotoxic periodic paralysis mainly appears in case of hyperthyroidism and the amyotonia is the characteristic main symptom. Through the deteriorated case and treatment by oriental medicine, the purpose of this research is to study the change of symptoms and the treatment effect for one case of a thyrotoxic periodic paralysis patient, Methods and Results : The treatment was carried out with oriental medicine as a main treatment and by the oriental medicinally deteriorated case, acupuncture treatment, moxibustion treatment and herbal medicine treatment were used as the main treatment methods. Also based on the symptoms which could appear with hyperthyroidism, the changes of symptoms were evaluated once a day with 4 levels of subjective scales that the patient was feeling, by dividing with 4 aspects of totalis symptoms, cardiovascular symptoms, musculoskeletal symptoms and other symptoms. In addition, it was shown that through the continuous hematologic test, the subjective and objective symptoms were mostly decreased during the treatment periods by comparing with the objective thyroid hormone (T3, T4, TSH) levels and the electrolyte levels. Conclusion : With this result, it was considered that oriental medicinal treatment was very effective for the thyrotoxic periodic paralysis through the oriental medicinally deteriorated case.

Purpose: This study was conducted to identify effects of Medicaid Case Manager's communication competence and stress on their job satisfaction. Methods: The current work is descriptive research, and the participants were 154 medicaid case managers. Data were collected between May and July, 2017 through Embrain, a specialized research organization. The data were analyzed using independent t-test, ANOVA, and multiple regression. Results: The mean communication competence of the medicaid case managers was 3.61, stress 1.76, and their job satisfaction 2.74. Age and average monthly compensation brought significant differences in their job satisfaction. Their communication competence was correlated with stress (r=-.35, p<.001), but not with their job satisfaction. The stress was the most influential factor in job satisfaction (${\beta}=-.45$). Conclusion: The results of this work show that the medicaid case managers' communication competence was not an influence factor of their job satisfaction, which is different from implications from the previous studies and needs confirmation through future research. In addition the results of this study also suggest that stress management can be a useful approach to the improvement of medicaid case managers' job satisfaction.

Purpose: This phenomenological study tried to understand the essence of the transitional care experience of medicaid case managers and its structural meaning. In addition, it was attempted to establish a system of transitional care and seek support measures for medicaid case managers. Methods: The participants of this study were 7 medicaid case managers who had spent more than 1 year and 6 months in medicaid pilot project. Data were collected with individual in-depth interviews from June to December 2021. The data were analyzed by Giorgi's phenomenological analysis method. Results: The seven constituents derived from the results of this study were 'struggle to establish a living environment', 'dedication to supporting independent living', 'anxiety about safety', 'pressure on care responsibilities', 'distress in building the pilot project', 'pride in role', and 'expectation for improvement'. Conclusion: The study results provide a comprehensive understanding of the transition care reality for medicaid case managers. They also shed light on managers' perceptions and attitudes. These findings can serve as fundamental information for establishing support measures for medicaid case managers and transitional care systems.

The effects of the addition of yeast on in vitro roughage degradability and methane production were investigated in order to clarify the effects of yeast on the rumen microbes and to establish methods of rumen manipulation. Three roughages (whole crop corn, rice straw and Italian ryegrass) were incubated for 3, 6, 12 and 24 h with or without dried beer yeast following the method described by Tilley and Terry. Using the same method, these roughages were incubated with or without yeast extract, albumin or purified DNA. In vitro methane production was measured with or without dried beer yeast at 12 and 24 h. The degradability of yeast was found to be 57 and 80% at 12 and 24 h, respectively. The rate of degradation of fraction b was 6.16%/h. There was a significant increase in roughage degradability at 6 h (p<0.05), 12 h (p<0.05) and 24 h (p<0.01) by dried yeast addition. The degradability of all three roughages was higher in the samples treated with yeast extract than in the no addition samples except in the case of rice straw incubated for 12 h. Nevertheless, the magnitude of increment was smaller with the addition of yeast extract than without the addition of yeast. With the addition of purified DNA, there were significant increases in roughage degradability at 6 h (p<0.01), 12 h (p<0.01) and 24 h (p<0.05); however, higher degradability values were detected in the samples to which albumin was added, particularly at 6 h. If the degradability values of the no addition samples with those of samples containing yeast, yeast extract, DNA and albumin were compared, the largest difference was found in the samples to which yeast was added, although it is worth noting that higher values were observed in the yeast extract samples than in the DNA or albumin samples, with the exception of the case of rice straw incubated for 24 h. Methane production was significantly increased at both 12 and 24 h incubation. The increment of roughage degradation and methane production brought about by the addition of dried beer yeast to the samples was thought to be due to the activation of rumen microbes. Water soluble fraction of yeast also seemed to play a role in ruminal microbe activation. The increment of degradability is thought to be partially due to the addition of crude protein or nucleic acid but it is expected that other factors play a greater role. And those factors may responsible for the different effects of individual yeast on ruminal microbes.

A clinical study was carried out 1 case of ischemic cerebrovascular accident which occurred at puerperium in a 27 year-old woman followed by vaginal delivery The results were as follows: 1. In the clinical view, it was thought that the cause of this case is intracranial venous thrombus, because the symptom-headache, foaming at the mouse, acromyotonia, hemiparesis- occurred in the postpartum and functional outcome is good. 2. In this case, the patient's functional system of spleen-stomach is usually weak, and due to delivery the functional system of spleen-stomach is more insufficient. so it can not control damp-phlegm(濕痰). In addition, vital energy of liver stagnate.

In our model, we keep inventory to satisfy uncertain demands which arrives irregularly. In this situation, we have additional two constraints. First, we need to have certain amount of order consolidation (consolidation constraint) for the orders to replenish the inventory because of production or purchase constraint. And also, if we order at a certain date which was set by administrative convenience, we have amount constraint to order the consolidated order demands (capacity constraint). We showed this variant inventory policy is needed in steel industry and note that there will be possible similar case in industry. To deal with this case, we invented a variant replenishment policy and show this policy is superior to other possible polices in the consolidation constraint case by extensive simulation. And we derive a combined solution method for dealing with the capacity constraints in addition to the consolidation constraints. For this, we suggest a combined solution method of integer programming and simulation.
