The effect of diets varying in level and source of nitrogen (N) and fermentable organic matter on dynamic characteristics of microbial populations in rumen liquor and their impact on substrate fermentation in vitro was studied. The diets tested were straw alone, straw+concentrate mixture and straw+urea molasses mineral block (UMMB) lick. The same diets were taken as substrates and tested on each inoculum collected from the diets. Diet had no effect on the amino acid (AA) composition of either bacteria or protozoa. Differences among the diets in intake, source of N and OM affected bacterial and protozoal characteristics in the rumen. Upper asymptote of gas production (Y$\alpha$) had a higher correlation with bacterial pool size and production rate than with protozoal pool size and production rate. Among the parameters of the gas production model, Y$\alpha$ and lag time in total gas has showed significant (p<0.01) correlation with bacterial characteristics. Though the rate constant of gas production significantly differed (p<0.01) between diet and type of straw, it was least influenced by the microbial characteristics. The regression coefficient of diet and type of straw for Y$\alpha$ indicated that the effect of diet on Y$\alpha$ was threefold higher than that of the straw. As microbial characteristics showed higher correlation with Y$\alpha$, and diet had more influence on the microbial characteristics, gas production on a straw diet could be used effectively to understand the microbial characteristics.

All the outdoor and indoor spaces are connected with each other. The human being moves toward those spaces and experiences temperature fluctuation between the natural and artificial temperature. We conducted an experiment which subjects are the college students wearing the data logger in urban life, and measured 24 hours' exposed temperature and thermal comfort in summer. Results were as follows. 1. Most subjects get weather information(84.6％). Fashion(46.2％) and weather (30.8％) are the reasons to select clothes. They spend their time in indoor environment for 84.92％ hours of a day and have an air-conditioner(61.5％) in their houses. 2. Exposed temperature fluctuation were from 33.8$^{\circ}C$ to 15.6$^{\circ}C$. The median value of experienced temperature were 26-27$^{\circ}C$ and average temperature was 26.3$^{\circ}C$. Subjects experienced cold shock of 3.96 times in a day and 67.21％ of all evaluated thermal comfort in the range of -1 and 1 by ASHRAE 7 Category Scales. Artificial environment which connected with outside let people experienced temperature fluctuation in wide range.

This study is to understand the inner psychological state of consumers who pursue a retail therapy effect through fashion product shopping. Qualitative research on the whole process from the point of time of occurrence of shopping motivation to the end of shopping motivation was performed. The researcher became a virtual shopping partner during shopping and conducted a natural conversation interview using a mobile instant messenger program (Kakao Talk). After shopping, participants were asked to write a diary on that day. Collected data were analyzed by applying the grounded theory approach suggested by Strauss and Corbin (1998). Casual Condition, represented everyday stress and Contextual Condition indicated the self-healing consumption trend. Main Phenomena showed a mood change during the fashion shopping process. The sense of emancipation from the place, the satisfaction from the maintenance of social relations, and the sense of accomplishment through purchases were revealed. Intervening Condition showed the consideration in the process of shopping for fashion products, such as providing a try-on experience, price promotion, and involvement of a companion. Action Interaction Strategy was the shopping behavior for the positive emotion increase and negative emotion decrease. Consequence represented a retail therapy in shopping for fashion products.

The participants were 40~60 years old women, assigned to the experimental group (n=25) or the control group (n=27). Auricular acupressure using vaccaria seeds was administered to the experimental group. The sessions continued for 6 weeks. Outcome measures included Pittsburgh sleep quality index, sleep meter, sleep diary, fatigue assessment instrument, serum cortisol, and serum serotonin. Results: Menopausal women in the experimental group showed significant increases in deep sleep, light sleep, serotonin level and sleep duration compared with the control group. Also, the experimental group reported decreases in PSQI, sleep latency, awakening time, fatigue and cortisol level compared with the control group. Conclusion: Results show that auricular acupressure using vaccaria seeds is considered as an effective treatment for sleep disorder and fatigue in menopausal women. We conclude that it can be used as a nursing intervention method proven to reduce sleep disorder and fatigue in menopausal women.

This study explored the overall perception of teaching media from the perspective of pre-service teachers. For this purpose, reflection journals written by 138 pre-service teachers were analyzed, and positive and negative perceptions of teaching media were explored. In the reflection diary, pre-service teachers were asked to write down examples of appropriate use of instructional media and the effects of their experiences, cases of inappropriate use of instructional media, and areas requiring improvement. The main research results are as follows. First, the positive aspects of teaching media perceived by prospective teachers were that it presented examples that could help understanding, aroused curiosity to focus attention, and encouraged participation to motivate learning. Second, the negative aspects of teaching media perceived by prospective teachers include cases where the playback time of the video containing learning content is excessively long and the content of the video is unclear or is higher than the learner's level and difficult to understand. This study is significant in that it presents pre-service teachers experiences and perceptions of teaching media and their desirable use methods.

Purpose: This study aimed to analyze the experiences of new nurses during their first year of hospital employment to gather data for the development of an evidence-based new nurse residency program focused on adaptability. Methods: This study was conducted at a tertiary hospital in Korea between March and August 2021 with 80 new nurses who wrote in critical reflective journals during their first year of work. NetMiner 4.5.0 was used to conduct a text network analysis of the critical reflective journals to uncover core keywords and topics across three periods. Results: In the journals, over time, degree centrality emerged as "study" and "patient understanding" for 1 to 3 months, "insufficient" and "stress" for 4 to 6 months, and "handover" and "preparation" for 7 to 12 months. Major sub-themes at 1 to 3 months were: "rounds," "intravenous-cannulation," "medical device," and "patient understanding"; at 4 to 6 months they were "admission," "discharge," "oxygen therapy," and "disease"; and at 7 to 12 months they were "burden," "independence," and "solution." Conclusion: These results provide valuable insights into the challenges and experiences encountered by new nurses during different stages of their field adaptation process. This information may highlight the best nurse leadership methods for improving institutional education and supporting new nurses' transitions to the hospital work environment.

Neo-Confucianism(性理學) which provided an ideological base to found Chosun Dynasty which substituted for Koryu Dynasty, presented In-Cheong(仁政) as ideal statecraft. In-Cheong(仁政) is realizing spirit of In(仁) which means a forever creating power(生生之心), for that reason it was a natural result that the ruling class of Chosun Dynasty had interest in medical science. Therefore they remarked 'In-Cheong(仁政) has achieved' when medical books were published, also remarked Hwal-In-Seo(活人署） as an institute of realizing Wang-Cheong(王政) while Hwal-In-Seo(活人署) was placed in very low civil service grade, although the ruling class classified medical science as a Chap-Hak(雜學) which means not essential but necessary knowledge, and ranked it much lower than Confucianism. While had improved medical service system of Korea Dynasty, Chosun Dynasty had special interest in local medicine: expanding provincal medical centers, educating a medical student(醫生) in a medical school who was core human power in local medicine, etc. Nevertheless the local medicine was still depressed. The reasons are ; not providing enough medical center, not much fund to run each center and mobilizing a medical student(醫生) for miscellaneous labor. Depressed local medicine had changed when 士族 came to have an interest in medical science. 士族 had read a lots of medical books from the early Chosun Dynasty. 16th century they even wrote some books on medicine by themselves based on their experience as a provincial governor.　On the other hand Yi-Mun-Geon(李文楗) who wrote Muk-Jae Diary belongs to the latter. He did not use the art of acupucture. He was a civil official in Seoul, so he could get a lots of books and enough medical stuffs. After a while. he was exiled in Seong-Ju(星州) and took part in local medicine there. The local medicine was depressed in Seong-Ju(星州) at that time. Yi-Mun-Geon(李文楗) was a kind of medical consultant as well as a local doctor. Such medical doings by Sa-Jok(士族) may be a moment that provide power to local Sa-Jok(士族). Sa-Jok(士族) themselves were enthusiastic in treating their sick slaves because the slaves were financial foundation of Sa-Jok(士族). After 17th century, however, the relative importance which Sa-Jok(士族) in the country had held in 16th century had decreased gradually while professional doctors bad increased.
