Ethylene was treated or inhibited to investigate its effect on the physiological changes related to induction of flesh browning in Fuyu persimmon fruit. The response of fruit to ethylene was so slight, that the Fuyu fruit seemed to possess a similar characteristic to non-climacteric fruit. The flesh browning was however enhanced by ethylene treatment, although any significant increment of phenolic content or PPO activity in flesh tissue was not detected. Ethylene induced not only increasing of ion leakage from fruit tissue, but the fatty acids extracted from ethylene-treated fruit tissue were also more saturated. It was suggested that ethylene be related in the changing of membrane permeablity via saturating of fatty acid in membrane lipid. That could result in increased leakage of vacuole-stored phenolic compounds, which oxidized further by PPO to cause fruit flesh to brown.

This research has a meaning to provide basic data for eco-friendly way of district unit plans and ecological landscape planning by evaluation of biotope preservation value at the level of district unit and designating land development of the site, the whole area of Sinseo-dong (Dong-gu, Daegu metropolitan city) for research site. The summary of analysis result is as follows. As a result of classification of biotope types on the research site, it is divided into 11 biotope groups such as a residential biotope group and 51 specific biotope types which is subordinate to the groups. As a result of the first value assessment on classified biotope types, there are 16 types of natural rivers which is full of vegetation as a I class. Also it is analysed as 9 types of IIclass, 14 of IIIclass, 8 of IVclass, and 4 of Vclass. In particular, in light of a wildlife habitat, EB, in case of broad-leaved tree of mixed forest assessed as a II class, was classified into Iclass which is one-step upgraded as a final class with the analysis as there is a structural characteristic (more than 71% of low density, 50 years of age-class). As a result of second assessment, it is analysed that there are 17 special sites (1a,1b) and 33 special sites (2a, 2b, 2c) respectively for preservation of species and biotope. Particularly, in case of the No. 27 space, it was assessed that it has the value of about medium (IIIclass) level, but its value was upgraded with the on-spot detailed investigation that most of Aristolochia contorta, designated as a rare plant by Ministry of Environment, is growing. It is regarded that the above-mentioned research result on evaluation of biotope preservation value is expected to provide very important basic materials for future district unit plans and smooth integration with landscape ecology plans and eco-friendly space development.

Archival appraisal has been a significant field and demanding task in thoughts and practice about modern archive, in particular, because of insufficiency of resources for the preservation in comparison with the large scale of recorded information. Appraising records does naturally go with the selecting and acquiring them. In the field of appraisal, however, comprehensive accountability on appraisal is much more important than selection and acquisition. The purpose of this study is the proposition of the theoretic approach to the analysis of the factors concerning the archival appraisal. For this purpose, I would try not the actual practice of the archival appraisal but theoretical categories of archival appraisal decision. The archival Characteristic, Value, and Context will be proposed as theoretical categories for the analysis of archival appraisal decision. Firstly, Characteristic category makes it clear to identify the reliable and authentic records, and then, Value provides us with elucidation about the appraisers' recognition of values. Lastly, Context explains the priority of selection throughout creating, using, interrelationship, and social meaning of archives.

In this paper we propose Fourier magnitudes based privacy preserving clustering on time-series data. The previous privacy-preserving method, called DFT coefficient method, has a critical problem in privacy-preservation itself since the original time-series data may be reconstructed from privacy-preserved data. In contrast, the proposed DFT magnitude method has an excellent characteristic that reconstructing the original data is almost impossible since it uses only DFT magnitudes except DFT phases. In this paper, we first explain why the reconstruction is easy in the DFT coefficient method, and why it is difficult in the DFT magnitude method. We then propose a notion of distance-order preservation which can be used both in estimating clustering accuracy and in selecting DFT magnitudes. Degree of distance-order preservation means how many time-series preserve their relative distance orders before and after privacy-preserving. Using this degree of distance-order preservation we present greedy strategies for selecting magnitudes in the DFT magnitude method. That is, those greedy strategies select DFT magnitudes to maximize the degree of distance-order preservation, and eventually we can achieve the relatively high clustering accuracy in the DFT magnitude method. Finally, we empirically show that the degree of distance-order preservation is an excellent measure that well reflects the clustering accuracy. In addition, experimental results show that our greedy strategies of the DFT magnitude method are comparable with the DFT coefficient method in the clustering accuracy. These results indicate that, compared with the DFT coefficient method, our DFT magnitude method provides the excellent degree of privacy-preservation as well as the comparable clustering accuracy.

Web records is valuable information to preserve, because it can be used as a legal evidence about business or e-commerce of a public institution, but it is easily disappeared because of its volatile characteristic. Therefore, archival information package should be defined for long-term preservation. Web records can be stored in the archival information package for electronic records, because web records is a kind of electronic records. However, the NEO(NARS Encapsulation Object), the archival information package for electronic records in Korea, can't able to store web records, because it was developed without consideration of the characteristic of web records. In this paper, we define extended NEO based on the analysis of KoSurWeb and KoDeWeb, that archival information package for document of surface and deep web as well as the NEO. Web records can be preserved and utilized along with electronic records by using the extended NEO. Also it can be used for record and legal evudence by archiving web records of public institution about e-commerce.

This study was carried out to investigate the general characteristics, such as volume, pH, sperm motility and sperm concentration of the semen collected from Beagle dogs (age $24{\sim}48$ months, weight $10{\sim}15\;kg$) by using the method of digital manipulation of the penis, and the effect of preservation temperature and time on motility of fresh semen. Multiple ejaculates were collected from 4 male Beagles. The average volume, pH, motility and sperm concentration of the second fraction (contained with small volume of the third fraction) per ejaculation were $2.94{\pm}0.24(SD)\;ml$, $6.43{\pm}0.42(SD)$, $97.04{\pm}3.50(SD)%$ and $1.67{\pm}0.23(SD){\times}10^8\;cells/ml$, respectively. Average semen volume per ejaculate, semen pH, sperm motility and sperm concentration of the first fraction from the ejaculate were $1.24{\pm}0.20(SD)\;ml$, $6.03{\pm}0.26(SD)$, $1l.30{\pm}4.02(SD)%$ and $7.25{\pm}1.02(SD){\times}10^5\;cells/ml$. Those of second fraction were $2.52{\pm}0.32(SD)\;ml$, $6.32{\pm}0.31(SD)$, $96.25{\pm}3.52(SD)%$ and $2.35{\pm}0.35(SD){\times}10^8\;cells/ml$. Those of third fraction were $2.71{\pm}0.27\;(SD)\;ml$, $6.52{\pm}0.20(SD)$, $95.65{\pm}2.78(SD)%$ and $5.72{\pm}0.29(SD){\times}10^7\;cells/ml$. Motility of semen was higher at $17^{\circ}C$ preservation temperature than $5^{\circ}C$ or $36^{\circ}C$ during preservation period. When preservation temperature was $17^{\circ}C$, motility was $96.54{\pm}2.05(SD)%$ at 1 h, $90.20{\pm}3.90(SD)%$ at 6 h, $89.05{\pm}2.01(SD)%$ at 12 h, $78.21{\pm}3.50(SD)%$ at 18 h, $45.24{\pm}6.25\;(SD)%$ at 24 h and $30.75{\pm}17.24(SD)%$ at 30 h, respectively.
