Korea has kept its records of astronomical phenomena since around 2,000 years ago. However, the contents and scope of relevant service have been limited for researchers who need those records due to lack of complete data collection. In this regard, it is necessary to establish efficient collection and management systems of Korean astronomical records by utilizing an environment that is easily accessible. This study is intended to complete the development of a testbed system that allows researchers to systematically input and validate, in a Web environment, multiple astronomical records among the historical documents until Modern Joseon after the Three Kingdoms Period. Recognition of the pre-translated data and tables in advance is followed by its storage in the database built on the Web. Then, data validation is implemented by providing a retrieval service according to a specific form to only a finite number of researchers who have access authority. This study is targeted at a testbed system that takes around three months to be completely developed. The completed testbed system is expected to allow internal and external researchers of an organization to easily access the service on the Web. This will ensure that the accuracy of the data can be verified mutually and help identify areas of service improvement. The opinions collected regarding service improvement will be reflected in the future system. Eventually, domestic astronomical records will subsequently be able to be utilized internationally through the multilingual service.

The experiment was conducted to evaluate the ingestive behavior of lambs confined in individual and group stalls. We used thirty-four lambs in their growing phase, aged an average of three months, with mean initial live weight of $17.8{\pm}5.2$ kg. They were allotted in a completely randomized design with 24 animals kept in individual stalls and 10 animals confined as a group. The experiment lasted for a total of 74 days, and the first 14 days were dedicated to the animals' adaption to the management, facilities and diets. The data collection period lasted 60 days, divided into three 20-d periods for the behavior evaluation. The animals were subjected to five days of visual observation during the experiment period, by the quantification of 24 h a day, with evaluations on the 15th day of each period and an interim evaluation consisting of two consecutive days on the 30th and 31st day of the experiment. The animals confined as a group consumed less (p<0.05) fiber. However, the animals confined individually spent less (p<0.05) time on feeding, rumination and chewing activities and longer in idleness. Therefore, the lower capacity of lambs confined in groups to select their food negatively affects their feeding behavior.

Objectives: This study was conducted to test whether stretching helps high school students recover from their fatigue and improve concentration. Method: The method of this study adopted a nonequivalent control group with pre-test and post-test designs. The period of data collection was from November to December in 2004. The 135 subjects were randomly selected from two high schools in Ulsan : one school as control group(n=66) and the other school as an experimental group(n=69). The experimental group had stretching for 10 minutes before the start of their fifth period class, five times a week(once a day) 4weeks of period, but the control group did not do. Result: After stretching, the students' level of fatigue in the experiment group was immensely reduced (t=4.75, p<.001). After the stretching, the concentration level of the experimental group increased vastly compared to the control group (t=3.35, p≤.005). Conclusion: Stretching is useful to reduce fatigue and improve concentration of high school students. This study recommended that stretching, which is not limited by high physical techniques, or specific time or spaces would help high school students' health, since they do not exercise regularly and are tired physically and mentally.

Built in the 6th and 7th centuries during the Baekje period, the Buyeo Royal Tombs consist of seven tombs, including Tomb No. 1, which contains murals. To preserve Tomb No. 1 from damage caused by microorganisms, periodic microbial-distribution investigations are conducted. Following such investigations in August 2016, June 2018, and November 2019, the microbes were classified according to the investigation period, location of collection, and space. This study compares and analyzes the results. The concentration of airborne microorganisms in Tomb No. 1 and the number of microbial genera identified in each space of the tomb decreased as proximity to the main room with murals diminished. During the investigation period, the genera Bacillus, Cladosporium, Penicillium, and Streptomyces were commonly identified on Tomb No. 1. The microorganisms collected from the main room walls were mostly isolated from the east and west walls where the genera Bacillus, Cupriavidus, Paenibacillus, Pseudomonas, and Streptomyces were commonly identified in three or more walls. In particular, the genus Streptomyces is a dangerous strain capable of damaging murals by penetrating into and discoloring the pigments on them. The data generated from this study may be useful for future research on microbial distribution in other domestic mural tombs and those located in North Korea and abroad.

Objective : Establishment and development of Woongihak on Korea requires detailed study into its contents including each period's Woongihak theory and clinical practices. Method : Woongihak is assumed to have been introduced during the Coreyo Dynasty. Then its development stage is divided into early, middle, later periods in Chosun dynasty, and the category further developed into the Japanese colonial period and then the post-liberation era. These periods were given respect to while medical textx and data related to Woongihak were collected and analyzed. Result & Conclusion : The general consensus is that Woongihak was introduced for the first time during the early period of Coryeo Dynasty, but there was no text around this era regarding Woongihak could have been found. Woongihak was found in Uibang-yuchwi, which entered Chosun Dynastyin early period and was published, where it annotated Sanghanjiggyeog, Saminbang, and eumjeungyaglye. Donguibogam, which was published during the middle period, introduced Woongi by hosting a sentence of Cheonjiungi, and Chochanggyeol was published during the late period and brought the level of Woongihak in Korea a step further. Lectures on Diagram of Woongihakw as published during the Japanese colonial era, but it lacks uniqueness since it was a translation of Suwenrushiyunqilunao. Another book published during this period was OunyukgiUihakbogam by Cho Wonhui. It brought a heavy influence on the generations to come because it drew up prescriptions through the Gaegun and Gaeggi or Date of Birth of Date of impregnation. It was easy to use and highly potent. The author of this paper also collected about 55 types of Woongi texts published after the liberation of Korea, but there are sure to be many that is missing from the collection.
