A good arithmetic random number generator should possess full period, uniformity and independence, etc. To obtain the excellent random number generator, many researchers have found good parameters. Also an initial seed is the important factor in random number generator. But, there is no theoretical guideline for using the initial seeds. Therefore, random number generator is usually used with the arbitrary initial seed. Through the empirical tests, we show that the choice of the initial values for the seed is important to generate good random numbers.

New X-shaped crystalline molecules have been synthesized through various coupling reactions and their electronic properties were investigated. They exhibit good solubility in common organic solvents and good self-film forming properties. They are intrinsically crystalline as they exhibit well-defined X-ray diffraction patterns from uniform and preferred orientations of molecules. They also exhibited high field effect mobilities in thin film transistor (TFT) and good device performances.

The aim of this paper is to introduce good definitions of compactness, almost compactness, near compactness, weak compactness, and S-closedness in fuzzy topological spaces in Sostak s sense. These compactness related concepts are defined for arbitrary fuzzy sets and some of their properties studied.

This study is a descriptive research study conducted to find out the level of perception of the good death among nursing students and compare sub-factors among the perceptions of a good death. As for the research method, 102 people who explained the purpose of the study and agreed to participate were conveniently recruited. As a research tool, 'Measure of concept of a Good Death' by Schwartz et al. (2003) was translated by Lee (2017), and the research was conducted through online. For data analysis, statistical techniques such as descriptive statistics, frequency analysis, t-test, and one-way ANOVA of the IBM SPSS Statistics 26 program were used. Factors showing average differences in scores for each of the three sub-factors of good death awareness were derived from the experience of clinical practice. The mean of good death (3.13±0.36 points) of nursing students who experienced clinical practice was statistically significantly higher than that of students without clinical practice experience (2.90±0.31 points) (t=3.156, p=.002). In particular, the mean of good death for 'closure' was statistically significantly higher for those with experience in clinical practice (3.46±0.39 points) than those without experience (3.16±0.37 points) (t=3.476, p=.001). Through this study, it was confirmed that nursing students' perception of a good death differed depending on whether or not they were in clinical practice. The results of this study are expected to provide basic data for the establishment of effective educational strategies for the perception of good death in nursing students.

As the college environment changes, the roles of professors and students should also be changed. And the way that we teach undergraduate students should also be changed. The purpose of this research is to analysis characteristics of good teaching methods in college as perceived by students and professors. We did content analysis to elicit the characteristics of good instruction from qualitative comments of 196 course evaluations, 195 excellent essays selected from 8 college essay competitions, and 72 teaching knowhow essays of professors. To see the difference of division in good instruction characteristics, we did frequency analysis by SPSS statistics program. According to the content analysis, the most essential characteristics of good instruction as perceived by the students and professors is teaching strategies. There were also differences in the fact of recognition transition by division and the students-professors.

This study was executed in M elementary school for a week, T elementary school for a week, N high school for a week, and S high school for a week in 2000. There were mathematics teacher interviews, mathematics classroom observations, and student interviews in each school. We can draw the conclusion from this study as follows. Firstly, the teaching of mathematics in both elementary and high school was very good in the standard of mathematical concepts, procedures, and connection. Secondly, it is very good in the standard of mathematics as problem solving, reasoning, and communication. Thirdly, it is not so good in the standard of promoting mathematical disposition. Fourthly, it is good in elementary schools, but not in high schools regarding the standard of assessing students' understanding of mathematics. Fifthly, it is very good in elementary schools, but not so good in high schools regarding the standard of learning environments.

Spontaneous and isolated dissection of the limb arteries without involvement of the aorta is extremely rare, and has been reported previously in pregnant patients in association with collagen vascular disease, and in cases of high-energy trauma or intensive activity in athletes. There is no consensus yet on indications for medical or surgical therapeutic modality. Due to the rarity of spontaneous dissection of external iliac artery, its natural history has been poorly described. A healthy 50-year-old male with normotension was admitted with an acute onset of left flank pain. Left external iliac artery dissection was diagnosed by abdominal computed tomography.

This study was conducted to investigate the sanitation status and food waste state from 220 restaurant owners in Taejon area by questionnaires. As a result, the restaurant owners had proper knowledges on the purposes of the good menu system which is to prove public sanitation and to reduce food waste by changing present food service style. According to the restaurant management characteristics study, the subjects recognized highly for the importance of cleanliness(4.6), taste(4.5) where diversity of portion size(3.9), attractiveness(4.0) were low. 86.3% of the subjects mentioned great reductions in food waste after practicing good menu system. Also the subjects recognized the necessity for further researches on this field. After practicing good menu system in restaurant, their food waste was reduced.

This study investigated medical students' perceptions of good jobs. We classified medical students' perceptions of good jobs and analyzed the characteristics of each type. The Q methodology was used to extract medical students' subjective thoughts. After extracting statements based on previous studies, 46 Q samples were selected. The P sample consisted of 40 medical students divided evenly by gender and grade. They performed a Q sort of the 46 Q sample questionnaire and the results were analyzed using the QUANL ver. 1.2 program. Very few consensus statements were found in the replies. We divided answers into four types, each of which was clearly distinguished: (1) quality of life-oriented jobs, (2) reward-oriented jobs, (3) service-oriented jobs, and (4) self-realization-oriented jobs. Medical students in type 1 prioritized quality of life equally at work and at home. Medical students in type 2 preferred high-paying jobs. Medical students in type 3 placed importance on serving others. Finally, medical students in type 4 viewed good jobs as involving learning and development. The types of jobs sought were classified according to individual students' values and subjectivity. Medical schools may use the results of this study as a basis for career guidance.
