This study aims at developing a policy framework for a digital curation based on the access, co-ownership, reuse, and long-term preservation of digital information resources. To accomplish this, our study analysed a similar policy and support services of a main UK research institution and the DCC. It selected the main stages of the DCC lifecycle and developed a policy framework accordingly. Such a framework could serve as the basis for both state and individual institutions, and for developing standards and guidelines for a digital curation of digital information resources.

The greatest mission of archival community lies in collecting records to document past and present Korean society and in safeguarding them to pass over to the next generation. For the last decade, Korean archival community has actively pursued this mission and accomplished it to the certain extent. A series of events occurred during the last year urged the community to regretfully accept that the so-called accomplishment was by no means satisfactory. The present study aims to review what has been achieved against what should be if the community is to be truthful to the fundamental mission. It begins with addressing attributes of electronic records. To be specific, attributes of electronic records as 'records' are compared against those as 'digital objects.' Current state of long-term preservation of electronic records is reviewed. Suggestions follow in terms of four directions: establishing a policy framework based on principles of electronic records management, building integrated electronic records management system, researching and developing functionalities for long-term preservation, and finally, knowledge transfer and coordination.

This paper showed results of the risk management project in detail which was conducted by National Archives of Korea(NAK) in 2010. In the project NAK examined its long-term preservation business of electronic records using DRAMBORA(Digital Repository Audit Method Based on Risk Assessment). NAK has defined 44 different risk elements related to its business activities, assessed and classified them into several grades according to the severity calculated by risk probability score and risk potential impact score, and developed precise management plans for two of the most serious risks. This paper introduced the management plan for one of them. The risk was numbered with NR04 and described by 'Loss of integrity of records information'. This paper explained mitigation strategies, contingency organization, disaster control responsibilities, and personal mission cards for the NR04. This paper planned to give comprehensive understandings to Records Management Organizations about the risk management approaches as an effective way for business management through the case study.

This study aims to design folk song metadata based on the OAIS reference model for the folk songs' preservation and permanent use. Thus, the folk songs' general characteristics were investigated by researching literature and related technical standards. The type of records, the methods and standards for long-term storage of records, OAIS reference models, and each package's metadata elements were identified through opinions from the popular songs' creators and researchers. The results awere that first, folk songs were created for social transformation, serving as a cultural heritage different from popular songs given their noncommercial quality. Second, the types of folk song records were identified, and the long-term preservation system suitable for the types of records was based on the OAIS reference model. Third, the metadata were edited, and the OIS reference model was applied such that respect was given to the folk songs' characteristics, context, and original order. Fourth and last, information package metadata elements matching the folk songs' records were derived and applied to the representative Korean folk song, "The March for Being."

Cardiac valve allografts have been used as replacements for diseased valves and right ventricular outflow tract reconstruction, the long term follow-up of which has been reported satisfactory. For a good long-term result, it is essential that the allograft be viable at implantation. In this study, we aimed at preparing the cardiac valve allografts aseptically, preserving them at cold- and cryo-conditions, and testing the viability of the allografts after preservation by four methods. We tested the viability of the cardiac valve allografts preserved in cold refrigerated state[4$^{\circ}$C in nutrient media & in liquid nitrogen tank[cryopreservation under -149$^{\circ}$C for pre-planned time periods. The testing methods were 1 glucose utility test 2 tissue culture 3 thymidine uptake test and 4 histologic evidence by light microscopy. We observed no differences in the viability between cold- & cryo-groups and similar results among the methods for testing the viability. In conclusion, there was no difference in the viability between cold- and cryopreserved-allografts at least for 14 days of preservation. And glucose utility test and thymidine uptake test were satisfactory in the evaluation of the allograft viability, since they were easy and rapid with relatively quantitative results.

Recently, many Koreans have started to consume aged kimchi fermented long-term at low temperatures. In the present study, the effect of low temperature ($5^{\circ}C$) on pH, titratable acidity (TA), organic acid level, viable microbial cell count, amino acid concentration, and polygalacturonase activity (PG) during long-term fermentation (46 weeks) of kimchi, were evaluated. After 10 weeks of fermentation, kimchi had a pH of 4.1 and a TA of 1.0%, respectively after 46 weeks fermentation, these values were 3.9 and 1.3%, respectively. Lactic acid, the ratio of lactic acid to acetic acid, and the ratio of Lactobacillus species/Leuconostoc species in kimchi increased as fermentation progressed from 10 weeks to 46 weeks. However, total viable cell counts of aerobic bacteria, yeasts, Lactobacillus species, and Leuconostoc species, free amino acid levels, and PG decreased as the fermentation period was extended from 10 weeks to 46 weeks.

The hybrid ($CSR2{\times}CSR4$) eggs treated with acid were taken up for the study with an objective to develop long-term preservation schedule. The hybrid eggs obtained with two mating duration (3 h and 6 h) and oviposition period (6 h and 24 h) with two age groups of eggs (24 h and 36 h) were treated with Hydrochloric acid. These eggs were subjected to preservation at $5^{\circ}C$ in single step refrigeration and at $5^{\circ}C$ and $2.5^{\circ}C$ under double step refrigeration from $10{\sim}120$ days. These eggs were released from the cold storage as per the specified durations and incubated at standard conditions and allowed 2 h for hatching at 450 lux light. Hatchability was found to be significantly higher or on par with the control in three treatments (T1, T2 and T4) where the eggs are preserved continuously at $5^{\circ}C$ up to 30 days. However under double step refrigeration, hatching was not significantly affected in 20+60 day's combination of T1 treatment up to 80 days. Bioassay studies of the promising treatment i.e.. T1 with (20+60) days indicated that early stage loss and cocoon yield was found to be on par with the control. Hence this treatment was recommended for preservation of acid treated new bivoltine hybrid layings. Details of the hatchability and rearing performance of long term preservation of acid treated eggs are discussed.

Objectives There is growing interest in the management of cancer survivors due to the increase in long-term survivors. But no literature research focusing on the management of cancer survivors has been done in Sasang Constitutional Medicine despite the superiority in comprehensive management of patients. Therefore, we planned to look into the perspective of health preservation in Sasang Constitutional Medicine.Methods We investigated the 『Donguisusebowon-Sasangchobongwon(東醫壽世保元 四象草本卷)』. We classified the contents which might be applicable to cancer patients. After classifying, we compared the contents with clinical experience and health preservation methods of Western Medicine.Results and Conclusions The health preservation is mentioned mostly as Joyang(調養). The Sasang Constitutional Medicine classifies the lives of people in 8 stages. Depending on the stages, there is a difference in the prognosis and management. Cancer patients can be regarded as being in the stages of Noeok(牢獄) and Wiegyeong(危傾). In these stages, patient's health preservation is important. In order to achieve long-term survival and to prevent disease progression, it is important to maintain requisite energy(保命之主). The attitudes that patient must have are simplicity(簡約), attentiveness(勤幹), vigilance(警戒), knowledgeability(聞見) for keeping one's own health and fulfilling the social obligations of human relations. The concept of health preservation in Sasang Constitutional Medicine covers the wide range of health. But detailed methods for patients to understand and practice are lacking. Moreover, it is hard for cancer patients to access the information. Therefore, further researches should be done to make the concept more specific and easy to access for cancer patients.

During storage, boar spermatozoa undergo several changes including diminished motility and viability and accumulated reactive oxygen species (ROS). In this study, we investigated the effects of green tea extract (GTE) supplementation in the Sui Dil extender on the sperm motility, viability, ROS and lipid peroxidation (LPO) of long-term preserved boar semen at $17^{\circ}C$. A total number of eight boars were used for this experiment. Pooled ejaculates were diluted to $20{\times}10^6sperm/ml$ in the Sui Dil extender containing 0 (control), 1, 10, 100 or 500 mg/l GTE and were preserved at $17^{\circ}C$ for 24, 72, 120 and 168 h, respectively. At each storage time, sperm motility and viability were estimated by microscopic examination and the fluorescent double stain $Fertilight^{(R)}$, respectively. Sperm ROS level and LPO were assessed using the 2', 7'-dichlorodihydrofluorescein diacetate ($H_2DCFDA$)/propidium iodide (PI) and C11-BODIPY581/591/PI with flow cytometry, respectively. Compared to that of the 500 mg group, there were higher sperm motility and viability in the 1, 10 and 100 mg GTE groups during the preservation from 24 to 168 h (p < 0.05). The ROS levels of the 10 and 100 mg groups during the 168 h preservation were lower than those of the 0, 1 and 500 mg groups (p < 0.05). There were no significant differences in LPO regardless of the preservation period or the GTE concentration. In conclusion, the optimal concentrations (10 and 100 mg/l) of GTE that led to lower ROS levels may be useful for liquid boar sperm preservation at $17^{\circ}C$ for a period of 168 h.
