Assessing values in establishing conservation principles has been at the heart of discussions for the last twenty years since conservation has been recognised as a social process to include various kinds of stakeholders for making a rational decision rather than a single scientific activity by a small group of experts. Such perception makes values attributed to cultural heritage important in deciding the reason why, the way how to, and the thing what to conserve making value assessment become crucial theme to understand and developing value-based conservation process. However heritage values, the way of assessing them, and establishing value-based conservation principles have been less studied in Korea. This thesis aims to initiate studies of heritage values and encourage discussion for setting out value-based conservation principles. It has three main chapters: 1. to analytically review previous studies on value assessment to redelineate various kinds of values which can be attributed to Korean cultural heritage; 2. to examine affecting factors in assessing values and significance, which are authenticity and historical and cultural dimension of value assessment; 3. to develop a process to establish value-based conservation principles. This study left several areas to be developed in future studies: 1. deeper understanding of various kinds of values from local perspective taking actual cases; 2. addressing problems in compromising conflicting values and providing solution to conserve all attributed values withing devaluing certain aspects of values; 3. providing guidance for practicing value - based decision - making process and setting out regular training opportunities for heritage - related professionals.

The growth and microstructural characterization of epitaxial yttrium silicide ($YSi_2$) on the (100)Si substrate are investigated. The $YSi_2$ film grow epitaxilly through the solid phase reaction during vacuum annealing above $400^{\circ}C$. The epitaxial relationships between the hexagonal $YSi_2$ film and the (100)Si substrate are [0001]$YSi_2$//[011]Si and [0001]$YSi_2$//[011]Si in the (1100)$YSi_2$//(100)Si plane relation. The YSi$_2$ film consists of the two types of domains which have two different azimuthal orientations making an angle of $90^{\circ}$ to each other. The two types of domains in the $YSi_2$film are equivalent in volume fraction and crystalline quality, which has been proved from the equivalent integrated intensities of (2201) asymmetric reflection of X-ray diffraction. The formation of a double -domain structure is discussed on the basis of geometrical matching at interface between the (1100)$YSi_2$ film and the (100)Si substrate, and growth model is proposed.

A microplate enzyme-linked immunosorbent assay (ELISA) for detecting antibodies to bovine leukemia virus(BLV) is described and compared its sensitivity with that of the agar gel immunodiffusion test (ID) with BLV glycoprotein (gp) antigen using 263 sera collected in Korea and Japan. There was 98.5 per cent agreement between ELISA and ID when ELISA value, the value of tested serum(T) was devided with that of standard negative seurm(N) after the value of control was eliminated from T and N (T-C/N-C), of 1.5 or greater was considered positive. One hundred and forty four (99.6%) of 145 sera which were positive by ID were greater than 1.5 by ELISA, and 115 (97.5%) of 118 sera which were negative by ID were less than 1.5 by ELISA. As a result, it suggest that the ELISA test using BLV-gp antigen provides a useful serological tool for the diagnosis of BLV infection.

In this paper, setting and strength performances of concrete containing saccharic type super retarding agents are investigated under various kinds and contents of super retarding agents. According to test results, as super retarding agents contents increase, slump shows to be increased, while air contents decrease about 1∼2％. Setting time shows to be retarded considerably with increase of super retarding agents. It takes 20 days after mixing to reach final setting in case of concrete containing gluconic acid more than 0.3％. And 10 days after mixing in case of enhancing sucrose, white and brown sugar. Compressive strength of concrete containing super retarding agents is lower than that of plain concrete at early age. However, it keeps up with and exceeds the compressive strength of plain concrete at later age. White sugar md brown sugar shows positive performances in delaying setting time and strength compared to existing super retarding agents. n further investigations on durability are conducted, it is thought that application of white sugar as super retarding agent is available.

The purpose of this study is to examine the effects of team based learning on academic achievement, problem solving skill, and communication ability in high risk pregnant nursing. This experimental study is designed for a equivalent control group. The program was put into practice 1 times a week for 8 weeks. The number of subjects in this research consists of 120, where 60 of the experimental group participated in team based learning program and 60 of the control group didn't do. The data was analyzed by ${\chi}^2-test$, Fisher's exact test, independent t-test, and paired t-test. The effects of team based learning approaches on learning outcomes in high risk pregnant nursing are as follows: The problem solving skill of the experimental group has been significantly more elevated than that of the control group. The experimental group has made increase in communication ability. This study has significance in that it identified the availability of the team based learning program and that it would be useful teaching and learning method to achieve learning outcomes.

The purpose of the study was to review the evidence of effects of virtual reality (VR) technology in nursing education. Four databases were searched for articles publised until November 2018 that databases include PubMed, Proquest (nursing and allied health), CINAHL, & RISS. Key word used for search include 'education, nursing', 'simulation', 'skill training', 'virtual reality' and 'VR'. Of 695 papers searched, Seven studies were selected for data analysis. Of seven studies, five studies used quasi-experimental design and two used one group design. There were two studies used VR technology for skill training and five were scenario based VR simulation program. Studies evaluated outcomes including students performance, time spent on practice, self-efficacy and communication ability that most studies reported positive effects while some figures were not statistically significant. The findings of this study provides evidence of nursing education program using VR, however, additional research with rigorously designed studies using systematized measurements for study outcomes are required. In addition, comparison with existing skill training and simulation education should be considered in the future studies.

Survival and stability of 19 bifidobacterial strains included 13 isolates from Korean infants against acid, bile acid and oxygen exposure were examined. Acid resistance of selected strains at pH values of 4.0, 3.0 and 2.0 was tested. Among the bifidobacterial strains tested, B. bifidum B3, B. longum D6, and B. adolescentis F1 exhibited higher viable cell counts exposed to acid whereas other strains had various results. The abilities of the strains to grow in the MRS broth containing 0.2% thioglycolic acid and 0.2% oxgall were tested and the tolerance of B. bifidum B3 and B. longum D6 to bile acid were higher than that of others. Even though in same species, the tolerance of tested strains to bile acid were variable. Stabilities of tested strains to oxygen exposure were variable and B. bifidum and B. longum strains showed relatively higher viable cell counts after 48 hours exposure to aerobic incubation. These results demonstrated that the survival and stability of bifidobacterial strains to acid, bile acid, and oxygen exposure were variable and strain-dependent. Due to their tolerant ability to environmental factors like acid, bile acid, and oxygen, B. bifidum B3 and B. longum D6 had good potential properties as probiotic cultures and may be useful for industrial application.

The purpose of this study was to review meditation programs for stress relief of Korean nurses. Whittmore and Knafl's integrative review methods were used. The search yielded 97 articles, 7 of which met the criteria and were included in the review. One of the selected studies was a randomized controlled quasi-experimental design and six were a non-equivalent control group pretest-posttest design. Meditation programs varied from 5 to 8 sessions. All of the meditation programs measured the effect on stress as various meditation programs. However, there was one study confirming the degree of stress management maintenance after the end of the meditation program. Although there are contents to strengthen the practice and will of nurses, it was confirmed that it was difficult to evaluate sincerity. Therefore, a highly accessible program for nurses in various clinical situations and strategies to strengthen participants' practice and will needs to be included in the meditation program content.

A field experiment was conducted to evaluate effect of water soluble silicate fertilizer (WSS) application on rice plants with respect to comparing with powdery slag-originated silicate fertilizer (PSS) and granular one (GSS). The 30-day seedlings were transplanted on May 10, 2012. The plot size was $25m^2$, and the planting density was 15 hills $m^{-2}$. The standard application level was $2kg\;ha^{-1}$ for WSS, $200kg\;ha^{-1}$ for GSS, $200kg\;ha^{-1}$ for GSS. The application rates were 50 %, 100 %, and 200 % of the standard levels. The soil and plant samples were taken after harvest on September 10. Strength weight of the stem was measured on the center of the 5-cm of the fourth internode. Nutrient contents and yield of grains and were evaluated. The strength weight of the stem was positively correlated with the silicate content of the stem with the highly significant $R^2$ of 0.601. The strength of the stem was satisfactorily enforced by application of 50 % WSS and GSS, and 100 % PSS. Application of 50 % or 100 % of WSS showed little difference in rice yield in comparison with application of 100 % of PSS or GSS. Therefore, application of $20kg\;ha^{-1}$ of WSS would be recommendable for rice cultivation which enforced stem strength, and increased yield of rice.
