A urinary calculus in the urethra is rarely seen and usually encountered in men with a urethral stricture or diverticulum. Herein, we report a rare case of a giant calculus in the urethra of a 42-year-old male patient with paraplegia after spinal cord injury due to car accident 20 years ago. A recent urologic consultation from the emergency room was performed since the patient had multidisciplinary symptoms during the day without any urination and presented with urinary difficulties due to hematuria and pain symptoms occurring with a mass in the bottom of the testicles. Abdomen and pelvic computed tomography (CT) was performed to examine the tumor mass, which was found to be absent. In addition, urethral stones were observed in the CT. Cystostomy was performed after the first urethroplasty, and the stone was removed from the urethra. Two weeks later, the patient was subjected to urethrography to remove the Foley catheter. No specific finding in voiding was detected. Giant urethral stones sometime require differentiation from tumor status. Treatment may vary according to size and location, requiring careful examination.

The purpose of this study is to identify the existence, personal characteristics and behavior of market-participants, and function of urban weekly markets in Taegu City through observation, interview and questionnaire survey. There are four weekly periodic markets such as Seongso(Monday), Chilgok(Wednesday), Siji(Thursday), and Chilgok(Friday) which have recently developed near the new apartment areas on the outskirts of Taegu. The major findings of this study can be summarized as follows: These markets originated from the agricultural cooperative's Friday markets, but were substantially established by mobile traders or merchants for the sake of their livelihood. Therefore, the existence of these markets is not explained by Stine's central place perspective but partially explained by Hay's economic locational and Bromley's socio-cultural perspective. Most traders are male, aged 30 to 40 years and have an educational level higher than high school. Most of them are living in Taegu and itinerantly visit more than two markets among the four markets by small truck. And most of them sell agricultural products and other food materials, except some who sell manufactured goods. Most consumers are housewives, aged 20 to 30 years and have an educational level higher than high school. Most of them are living within 1,000m and go there on foot. Most of them visit the markets around 3 to 5 p.m. on every market day. And they mostly buy vegetables, fruits, and fishes. Weekly markets provide employment opportunities for those who want to be merchants, and also contribute to the increase of farmers' income, because some traders(18.8%) are farmers who periodically visit markets to sell agricultural products. On the other hand, they function as a general food materials markets to neighboring residents. From these facts, both traders and consumers want weekly markets sustained. Therefore, these markets need to be protected by institutional assistance in spite of being informal markets.

A transformation methode of the chromaticity coordinates was proposed to calibrate the measured data obtained by a urine analysis system which implemented in our previous study. Generally. the reacted color of a reagent strip by urine analysis system often exhibit the color distortions due to nonlinear characteristics of the various devices that is the optic module mechanism. hardware, and surround circumstance. A color correction method for minimizing the color distortion play a few role in maintaining high accuracy and reproduction of the urine analysis system. In this work, we used the compensation method such as the shading correction, the characteristic curve extraction of RGB color by means of third order spline interpolation, and linear transformation using a reference color. In addition, 1931 CIE XYZ color space was used to compensate the color of the measured data by a standard reference system as colorimeter. A compensation matrix was obtained so that the output values of the urine analysis system is nearly equal to that of a standard reference system for identical color sample. Color correction obtained by a urine analysis system which implemented in our previous study exhibited a good color accuracy when it was compared with the reference data. Observed result from an experiments on ten items or a urinalysis strip that color difference or between two urine analysis system was 1.28.

The central objective of this study is to curtail the leakage of mortar or cement paste, often resultant of ill-constructed formwork, by implementing thixotropy in the formulation of high-fluidity, standard-strength concrete. When such concrete is utilized in smaller scale construction projects, instances of formwork gaps due to suboptimal construction precision may lead to significant leakage of mortar and paste, a problem not typically encountered with traditional slump-flow concrete. In this investigation, Polyvinyl Alcohol(PVA) and borax are incorporated into the concrete mixture to induce thixotropy. The experimental design includes varying methodologies for integrating PVA and borax, while assessing alterations in diverse concrete performances, including thixotropy and leakage reduction potential that simulates formwork gap conditions. Under the experimental conditions defined within this study, it was found that replacing, rather than merely adding PVA and borax, aids in averting water addition via suspensions. This approach yielded promising results in terms of concrete properties and proved efficacious in stemming leakage in concrete possessing sufficient thixotropy. Notably, when a 6% PVA suspension was substituted, a significant reduction in leakage was observed. Consequently, it is projected that construction quality can be ensured, even with lower precision formwork, by applying thixotropy to concrete through the use of PVA and borax.

This study was to investigate two main purposes; The first was to explore the factors which have an effect on conceding seats to the old or the weak in subway(concessive action). The second was to examine the influence that the psychological burden and the responsibility had on concessive action and it's gender differences. The results of study 1 showed that affective empathy, morality, and negative-state relief were important inductive factors, while 3 factors were revealed as important inhibitory factors for the concessive action; psychological burden, repulsion for coercive demand for conceding seats and vagueness of concession situation. In study 2, We could find the fact that the psychological burden and the responsibility had a main effect on the concessive action. The more participants felt the psychological burden, they were likely to evaluate that the tendency to concessive action would be decreased. And the more participants felt the responsibility, they were inclined to evaluate that concessive action would be increased. Secondly, the interaction effect was also revealed: On the situation that the psychological burden was high and responsibility was low, participants judged that people tended not to concede seats. Finally, We were able to identify gender differences. Specifically, Judging the tendency to concessive action, women were more responsive to the psychological burden than men.

Maintaining the appropriate number of national seafarers is essential for securing the competitiveness of maritime industry and security in Korea. However, the number of national seafarers in Korea has been decreased continuously recently. The government recognizes the repercussion of this issue and has been attempting to solve it. One of the most significant reasons contributing to the rapid decrease in national seafarers is presumed to be the high initial turnover rate due to the decreased preference for maritime careers among people in the 20s and 30s. Therefore, plans have been devised to prepare various policies that allow young people to select long-term boarding. This study analyzed the determinants of long-term boarding decisions among students enrolled in the Maritime College of 'M' University and verifies the relationship with the desired boarding period. Additionally, the crew composition (CC), long-term planning (LP), work environment (WE), and family environment (FE) were derived as the determinants of long-term boarding recognized by prospective seafarers. Among them, LP and WE significantly affect the desired boarding period, thus suggesting that the stronger the perception toward long-term planning and the more insensitive one is to the work environment, the longer is the desired boarding period. In terms of group differences in the perception of long-term boarding, analysis results show that the several determinants of long-term boarding are recognized differently depending on gender. This study may facilitate the preparation of factors and group-specific policy measures to promote long-term boarding among prospective seafarers.
