Ceramic cultural artifacts restored with gypsum-based materials are prone to decay over time due to gypsum's natural absorption and release of atmospheric moisture, often leading to distortion and peeling of painted layers. This study proposes a new restoration material which utilizes extra hard stone, significantly superior in strength to regular gypsum. In order to enhance its physical properties and make it suitable for restoration of ceramics, extra hard stone is mixed with metakaolin. This mixture far surpasses regular gypsum in compressive strength(119MPa vs. 26MPa) while also maintaining a much lower wear rate(0.88% vs. 2.53%). Furthermore, the water absorption rate(2.9%) of the mixed material is over five times lower than that of regular gypsum(17.2%). When examined using a SEM(Scanning Electron Microscope), this mixture also proved superior to extra hard stone in terms of hardened density. The addition of metakaolin increases the mixture's strength and water resistance over that of extra hard stone and also improves its surface density, making it ideal for the restoration of ceramics. It has already been used to repair ceramic objects in the Museum's collection: Clay basin(sinan 18892), Buncheong ware bottle with incised peony design(jubsu 2034), Buncheong ware bowl with chrysanthemum(jubsu 1730). Results thus far have shown the mixture to be easy to inject and layer as well as harden into an even surface, which allows for smooth application of paint for color matching.

The self-directed inquiry to improve students' core scientific competency is an important teaching method. Students experience a variety of difficulties in carrying out their inquiry tasks, sometimes fail to produce the desired results, or fail to perform a meaningless inquiry. This study was conducted to identify the causes of difficulties and failures in students' self-directed scientific inquiry. The study involved 16 high school students with experience in science research at science high schools and science-focused high schools. The data collection consisted of in-depth interviews centered on semi-structured open questions. Qualitative data analysis was imputed by finding paragraphs from the interview material that might reveal the difficulties and failures experienced by participants and the reasons for them. The study found that most of the causes of failure were lack of ability, incomplete procedures, and selection of complicated tasks. A variety of cognitive biases, such as overconfidence, planning fallacy, and groupthink, were also analyzed as causes. Based on the results of the study, it is necessary to develop an educational strategy that students can be fully prepared to reduce their trials and errors in a self-directed inquiry maximally.

The importance regarding the notion of immediate medical treatment and nursing for the victims of sexual crimes is not widely recognized yet in Korea. Throughout this research is focused on the nursing systems and the system of foreign countries in reference to sexual crime victims, and the conclusion is as follows. In Korea, there are currently no educational or medical institutes for the medical handling for the victims of sexual crimes, and the role of nurses in the medical institutes is insufficient. In addition, the basis for the standard of operation regarding the initial response, evidence collection, pursuit of systematical evidence and data is not established even in the sexual assault counseling/advocacy center. Therefore, it is necessary to foster the sexual assault nurse examiner for the sexual crime victims, and to develop adequate training programs based on the present situation in Korea. Though the cooperation among government, medical institutes, and social movement groups, it is essential to initiate effective and publicly-trusted specialized training programs for forensic nurses who will be fully charged with the treatment of sexual crime victims. By introducing the sexual assault nurse examiner system, it can be possible to develop advanced treatment for the child or adolescent victims of sex crimes.

Recent improvements in the standard of living, national income and medical care, and a decline in the infant death rate which have occurred related to economic growth and modernization, have led to a longer average life-span and a higher ratio of elderly people in the total population, Therefore, not only in the field of nursing science, but also in the field of many other discipline, issues concerning the elderly have been given increasing interest. A great deal of effort has been spent on increasing the quality of life for elderly people. This study was conducted to analyze the correlation between social support and quality of life. The sample consisted of III subjects residing at home and 107 subjects residing in institutions all of whom were over 65 years of age. The data collection period was from October 23, 1990 to January 26, 1991. Social support was measured using the Norbeck social Support Questionnaire developed by Norbeck, translated by Oh, Ka Sil and quality of life was measured using the QOL scale developed by No, You Ja. Data were analyzed using pereentages, t-test, Pearson Correlation Coefficient and ANOVA. The results of this study are as follows : 1. There was a statistically signifivant difference in the level of social support between the two groups (t＝-8.83, p＜.001), The elderly at home reported a much higher level of social support. 2. There was a statistically significant difference in the level of QOL between the two groups (t＝-5.77, p＜.001) . The elderly at home reported a much more positive quality of life. 3. There was a positive correlation between social support and QOL for the elderly at home ard it was statistically significant (r＝.32, p＜.001). 4. There was a postitive collealtion between social support and QOL for the elderly in institutions and it was also statistically significant (r＝.19, p＜.05). 5. The relationship between the general characteristics of the elderly at home and the variables of social support and of QOL were as follows ; 1) according to sex(t＝10.57, p＜.01) and the number of offspring(F＝6.19, p＜.01), there was a statistically significant difference in social support. 2) according to amount of Pocket money, there was a statistically significant difference in QOL(F＝2.98, p＜.05). 6. The relationship between the general characteristics of the elderly in institutions and the two variables were as follows ; 1) according to sex(t＝6.24, p＜.05), the number of offspring(F＝6.16, p＜.001) and religion (F＝2.58, p＜.05), there was a statistically significant difference in social support. 2) according to religion, there was a statistically significant difference in QOL(F＝2.90, p＜.05). In conclusion, it can be said that social support is an important variable related to QOL in the elderly and that social support levels are higher for the elderly residing at home. Therefore, more specific and objective approaches and efforts are needed to effectively use resources to maintain the elderly at home and to enhance social support available to the elderly in institutions and thereby increase QOL regardless of residence.

This study was performed to analyze the occupational health nursing of support-project of health management skill for small-scale industries. The 2 subject centers were under the umbrella of Korean Industrial Health Association and data collection period was 2weeks from September 1 to 13. 1997 and time and motion study method was used. Data was handled by SPSS win 7.5 program. results were worked out number. percentage. F-value. (1) The weekly time spending of occupational health nurses was distributed into indoor service 46.9%, outdoor service 26.6%, movement 26.5%. The mean visiting times were 2-3 times per week. and spending time was about 1 hour per industry. (2) There are statistically significant difference among the distribution of time spending according to industrial works(F=23.08. p=.000). and the special education for occupational disease prevention takes the most mean time. (3) There were statistically significant difference among the spending time for the health coach of occupational health nurses(F=188.79. p=.000). and the activity time for workers (58.4%) was more than that of for monitors(41.6%). The frequency of health coachs were 155 times for monitors during two weeks. but health coach for worker was 87 times. As a results. the contents of health coach for workers was proved to take more time than that for monitors. Perhaps we think that monitors has limitation for health management. therefore we should be consider flexible management of visiting time and health coach guidelines for occupational health nurses. (4) There were statistically significant differences among the distribution of time spending according to health coach methods for industrial health nurses(F=66.31. p=.000). The most frequent method of all was guide transmission. 159 times(65.7%), and the mean spending time for instruction was 19.78 min. the longest time. Our suggestion for occupational health nursing of support-project of health management skill for small-scale industry is that the need of each industry is very complex because of various conditions. therefore need assessment for industries should be conducted professionally. And occupational health nurses should apply occupational health nursing process autonomously. and their activities be guaranted by the guideline

With the increase of decrepit facilities, construction waste increased to a certain level and now the increase is more or less stabilized. Yet construction waste still constitutes the largest portion of the overall wastes. Also, it is inevitable to spend a huge amount of the national budget due to the aggravating shortage of aggregate caused by prohibition on collection of natural aggregates as well as due to the damage to the land and environment caused by development of the sources of aggregates. As a countermeasure to the situation, the Ministry of Land, Infrastructure and Transport promulgated the quality standard for recycled aggregate to manage the usage of recycled aggregate according to its quality. But use of recycled aggregate for the purpose of high added value still remains nominal. Therefore, this research aims to study the applicability of recycled aggregate concrete as structural concrete by evaluating the quality improvement effects and the performance of the recycled aggregate concrete including recycled fine aggregate and recycled coarse aggregate that have undergone carbonation for 4 days and 14 days respectively in the condition of 60% RH, 20% $CO_2$ and $20^{\circ}C$ temperature, suggested for carbonation modifying from the advance research. The result shows carbonation modify contributed to quality improvement with 0.91% decrease in absorption rate for recycled fine aggregate and 0.7% decrease in absorption rate for recycled coarse aggregate. The physical properties and durability of the recycled aggregate made of aggregate modified by carbonation showed results similar to general concrete, which confirmed the possibility of applying the recycled aggregate made of recycled aggregate modified by carbonation to structural concrete.
