UNESCO World Heritage Programme was introduced following the adoption of Convention Concerning the Protection of the World Cultural and Natural Heritage by the General Conference of UNESCO in 1972 in order to protect cultural and natural heritage with superb value for all mankind. Despite its short history of less than 40 years, it has been evaluated as one of the most successful of the cultural area projects of UNESCO with 890 world heritage registered worldwide. For systematic protection management of World Heritage, UNESCO, through systemization of registration, emphasis on the importance of preservation management plan, institutionalization of monitoring, and operation of World Heritage Fund, has utilized World Heritage Programme not just as a means of listing excellent cultural properties, but as a preservation planning tool, and accordingly, such policies have had a significant influence on the cultural heritage protection legislations of numerous nations. Korea has ratified World Heritage Convention in 1988, and with the registration of the Royal Tombs of the Joseon Dynasty in 2009, it has 9 World Heritage Sites. Twenty years have passed since Korea joined the World Heritage Programme. While World Heritage registration contributed to publicity of the uniqueness and excellence of Korean cultural properties and improvement of Korea's national culture status, it is now time to devise various legislative/systematic improvement means to reconsider the World Heritage registration strategy and establish a systematic preservation management system. While up until now, the Cultural Properties Protection Law has been amended to arrange for basic rules regarding registration and protection of World Heritage Sites, and some local governments have founded bodies exclusive for World Heritage Site management, a more fundamental and macroscopic plan for World Heritage policy improvement must be sought. Projects and programs in each area for reinforcement of World Heritage policy capacity such as: 1) Enactment of a special law for World Heritage Site preservation management; 2) enactment of ordinances for protection of World Heritage Sites per each local government; 3) reinforcement of policies and management functionality of Cultural Heritage Administration and local governments; 4) dramatic increase in the finances of World Heritage Site protection; 5) requirement to establish plan for World Heritage Site preservation protection; 6) increased support for utilization of World Heritage Sites; 7) substantiation and diversification of World Heritage registration; 8) sharing of information and experiences of World Heritage Sites management among local governments; 9) installation of World Heritage Sites integral archive; 10) revitalization of citizen cooperation and resident participation; 11) training specialized resources for World Heritage Sites protection; 12) revitalization of sustainable World Heritage Sites tourism, must be selected and promoted systematically. Regarding how World Heritage Programme should be domestically accepted and developed, the methods for systemization, scientific approach, and specialization of World Heritage policies were suggested per type. In the future, in-depth and specialized researches and studies should follow.

The purpose of this study is to examine the effect of care workers' employment characteristics and perception of facility directors' transformational leadership on quality of service through a hierarchical linear model. For this aim, survey data were collected amongst 240 older adults and 200 care workers who are affiliated within 45 long-term care facilities in Seoul, and analyzed using SPSS 26.0 and HLM 8.0. As a result, one's perception of transformational leadership had a positive effect, whereas, among employment characteristics, employment type and working hours had negative effects on quality of service. Regular workers with fewer working hours and higher awareness of transformational leadership toward the director provided higher quality of service. But wage, total experience and tenure didn't meaningfully affect it. Therefore, the following suggestions were presented. First, it is necessary to reorganize incentive, salary systems and budgets, changing the status of temporary workers' hourly wage system into that of regular workers' monthly one in order to strengthen employment security with acknowledging fundamental professional values through reinforcement of expertise. Reinforcement of long-term care's publicness and establishment of base facilities are also suggested. Second, maintaining appropriate hours of work and rest including annual leave under the Labor Standards Act is needed. Also, increasing the salary of and decreasing working hours for night shift workers are required. Third, education and intervention for inspiring transformational leadership of directors and strengthening qualification standards of them are required.

Asiatic black Bear(Ursus thibetanus ussuricus) cubs aged one or two were introduced from Russia(Primosky krai) and North Korea for reinforcement of the bear population and they were released to grow wild in Jirisan National Park. We did research on the characteristics of the denning sites of the Asiatic black cubs, which were released before, from Oct. 2004 to Apr. 2006, and the results were as follows: The released bears hibernated in three types of dens,; tree hollows, rock hollows or ground nests. The hibernating sites were dominated by a community of oak trees and its location was at an average of $923{\pm}221m$ height above the sea level ; the average slope incline was $25.9{\pm}7.9^{\circ}$, and the average denning duration was $98{\pm}9$ days. It was analyzed that the cubs' denning site was $2.8{\pm}2.8km$, on an average, far from the release point; $2.0{\pm}0.9km$ far from villages; $1.9{\pm}1.7km$ far from park inspection trails, and $1.9{\pm}1.0km$ on the average far from a driveway. It is assumed that environmental attributes of the denning sites were closely correlated to those of the release points.

The channel of distribution exists for the purpose of moving product from the manufactuerer to the final consumer. In order to satisfy consumer needs, channels provide for the those products to arrive at the right place, at the right time and in the quantity, quality and price desired. Currently, there has been an emerging interest in the improvement of distribution system in many areas of industries and Korean government because of a market liberalizatiion begun at 1989 and still has processed step by step. In the wave of market liberalization, an understanding of the channel of distribution and structure would be very crucial when developing the opportunities of competitive advantages in Korean apparel industry. The purposes of this study were to investigate the determinants of the distribution channel and to identify how to respond to the market liberalization for developing the possible future strategies in the apparel industry. Data for this study were obtained from interviews with managers in apparel company in addition to a questionnaire mailed to over 106 middle management position of apparel company. Data were analyzed by using descriptive statistics. The results of this study were summarized as follows. 1. In the distribution channel of the apparel industry, a vertical marketing system, comprising producer, apparel company, retailer, prevailed without intermediaries such as wholesalers or vendors. Especially, the apparel company controlled marketing channel members. This type of system may reflect added product cost and may be not advantageous to retailers and consumers because most apparel companies are responsible for its own transfortation, storage and stocks after season. 2. In the view of market liberalization, most apparrel companies showed double-edged viewpoints. In terms of positive aspect, it would give stimulus to broaden variety of fashion merchandise and to improve product quality of fashion merchanise which were the most disadvantageous factors in competing with oversea's brands. In terms of negative aspect, it would bring the bankruptcy of small or medium sized apparel firms and the foreign products' penetration in domestic market. From this study, severel recommedations were suggested forward to improve the present condition in apparel industry. They included eliminating the power of apparel company and reinforcing middlemen for more efficient distribution system and for satisfying consumer needs in rapidly changing environment. Also it included government supports, reinforcement of information system, improvement in channel structure, and career development program in conjunction with apparel companies and academic society for improving scientific management and future potential strategies in Korean apparal industry.

An almost permanent anchor (friction type) is resistant to ground deformation due to the friction between the soil and grout at a fixed length from the anchor body. The purpose of this study is to calculate the force of bearing resistance for a bearing anchor in enlarged boreholes. We conducted analytical and numerical analyses, along with laboratory testing, to find the quantities of bearing resistance prior to grouting in EBA (Enlarged Bearing Anchor) construction. The force of bearing resistance from the analytical method was defined as a function of general borehole diameter, expanded borehole diameter, and soil unconfined compressive strength. We also employed the Flac 3D finite difference numerical modeling code to analyze the bearing resistance of the soil conditions. We then created a laboratory experimental model to measure bearing resistance and carried out a pull-out test. The results of these three analyses are presented here, and a regression analysis was performed between bearing resistance and uniaxial compression strength. The laboratory results yield the strongest bearing resistance, with reinforcement 28.5 times greater than the uniaxial compression strength; the analytical and numerical analyses yielded values of 13.3 and 9.9, respectively. This results means that bearing resistance of laboratory test appears to be affected by skin friction resistance. To improve the reliability of these results, a comparison field study is needed to verify which results (analytical, numerical, or laboratory) best represent field observations.

Concrete is an outstanding material in terms of its impact and blast resistance performance. However, there a limitation of concrete is its risk of collapse due to the brittle failure and spalling. Increasing the thickness of members was used as a method to enhance the protective performance of concrete, despite the resulting inefficient space. To solve this problem, different types of fiber reinforced concrete were developed. Recently, another type of fiber reinforced concrete is also being developed and applied as a material that offers protection against impacts and blasts by increasing the flexural toughness of concrete. In this study, the test was conducted to evaluate the impact resistance performance of fiber reinforced concrete and mortar according to impact of high-velocity projectile. A concrete T-wall was also tested to evaluate its protective performance from fragment by 155mm-thick artillery shell. The test results revealed that improving flexural strength through fiber reinforcement inhibited cracks and spalling of rear, and spalling of front by high-velocity impact. As such, it is expected to improve the protective performance of the T-wall and reduce the thickness of the member.

In this study, I made researches of 510 mothers who breed their infants in total (256 boys & 254 girls), among which 410 in urban area and 100 in the rural area, as an object of the investigation so as to make an intensive examination and analysis of the actual state of feeding nutritive method, grasp several related factors, and finally suggest the elementary data for both campaign encouraging breast feeding and the infant feeding education. 1. Mothers showed the meaningful local differences as in an education and income level at 1% and as in a delivery type at 5%. 2. To have decided the feeding conditions according to the residences by the Kaup index distribution (P<0.05) resulted in a meaningful difference according to regions and also made us be more thoughtful of the overnutrition in the urban area than in the rural area, and it didn't showed a meaningful difference the nutritive state according to the infant feeding method thought desirable (P<0.01). 3. The feeding methods consist of breast feeding at 21.8%, artificial feeding at 48.8%, and the mixed one at 29.4%. As for the feeding method thought desirable, breast feeding was 52%. Even though they were thinking that breast feeding is better, the breast feeding case didn't go beyond 32.5% only and as for the actual feeding methods it showed a meaningful difference according to the feeding method thought desirable (P<0.01). 4. Regarding the reasons why they chose breast milk, it was 64%, the most because mother's milk contains the immune system, 63.1% for the baby's health, 52.3% because of its most because breast milk is of little quantity, 37.8% because of the mother's occupation, 14.1% because they have fed the baby artificially from the beginning and so on. Considering the reasons why they chose the mixed feeding, it was 70.7%, the most because the amount of breast milk a little, 27.3%, the next one, because of the mother's occupation and so on. 5. The respondents who answered that how to increase the number of breast feeding population depends on the reinforcement of breast feeding education for the women were 190 (37.3%), the most among all 150 persons and those who had the opinion that they should spread and actualize the temporary childcare rest (from office) system for the women who have jobs were the secondly most, 107 (21%).

In this study, we developed a repair material incorporating PVA powder resin and nylon fiber into cemented carbide used in the existing field to improve adhesion performance and water tightness with existing concrete. Flexural behavior evaluation was performed. The main experimental variables were PVA powder resin, nylon fiber mixing rate and damage type, and performance tests were conducted to evaluate compressive strength and flexural behavior after repairing materials. It was found that all formulations fully satisfied the required performance of the repair material. The flexural strength test results of the repaired tube specimens showed that the performance of the repaired materials was maximized when the nylon fiber was added and the PVA powder was added in an appropriate amount. The flexural behavior of all the specimens showed the flexural behavior of the structural members with a low rebar ratio, suggesting that the amount of iron wire in the domestic fume pipe was somewhat insufficient. That is, it was confirmed that the amount of reinforcement of the steel wire was somewhat small, so that the concrete was cracked before the behavior of the concrete and the steel wire reached the extreme state, and the concrete was immediately destroyed beyond the tensile strength of the concrete.

There are many types of remodeling, however, engineers and architectures preferred to merge two or more separate units to one very spacious unit. Performing this type of remodeling, in the case of wall dominant apartments, requires partial removal of structural wall causing a concern of structural integrity. However, there are insufficient studies about partial removal, that is, openings. Presently, ACI standard have no clear way to evaluate the effect of opening on the structural wall. AIJ has the provision about strength reduction factor '$\gamma$'. However, this reduction factor cannot exactly evaluate the reduction effect of openings because this factor '$\gamma$' was determined through the elastic analysis. Therefore, in this study, 2 structural wall specimens were tested and many test results from previous studies were collected. Using these data, this study performed statistical analysis about strength of structural wall which have the opening in wall panel. And this study performed parametric study verifying shear strength reducing effect by opening area. In the results of statistical study, previous reduction factor show very conservative results because this equation did not consider other factors, reinforcement ratio and aspect ratio of openings, which was affect the shear strength of shear walls. Therefore we performed parametric study based on the test data and suggest new equation for shear strength reduction factor '$\gamma$'.

Assessment and damage reduction strategy of acidic rock drainage were conducted in a section of ${\bigcirc}{\bigcirc}$ highway construction site. The geology of the studied section consists of Icheonri sandstone and intermediate to acidic volcanic rocks. Sulfides occur as a disseminated type in sandstone and volcanics which were altered by the hydrothermal solution of granite intrusion. Volcanics and sandstone with a high content of sulfide were classified as a potentially acid rock drainage(ARD) forming rock. The drainage originated from those rocks may acidify and contaminate the surrounding area during the highway construction. Therefore, the drainage should be treated before it is discharged. A slope landslide hazard due to the ARD was also expected and the coating technology was recommended for the reduction of ARD generation as a preemptive measure before reinforcement work for enhancing slope stability such as shotcrete and anchor. According to the ARD risk analysis, those rocks should not be used as cement aggregate, but only to be used as a bank fill material of a filling-up system that allows minimal contact with rainfall and groundwater.
