Accidents associated with hazardous materials, including oil and HNS, in maritime transportation show increasing trend. Therefore, preventive countermeasures for such accidents should be provided. The purpose of this study is to analyze level of risk on human loss and potential damage to environment, using data on domestic marine accidents carrying hazardous materials (2002~2014), and identify high-risk accident types for urgent risk management which needs findings of accident causes and proper mitigation measures. High-risks on human loss are explosion and suffocation, occurred in process of ship maintenance and tank cleaning. On the other hand, high-risk on environmental damage is spill caused by ship accidents (collision, grounding and etc.). Especially, spill occurs during loading operation of oil and HNS onboard a ship. Strict operation supervision/management and safety education/training on a regular basis could prevent accidents, because human factors such as not wearing safety gear and careless cargo handling cause most of the marine accidents.

Under the Korean Marine Environment Management Act (hereunder, the KMEMA), the duty to arrange spill clean-up equipments, including spill clean-up vessels, required by the article 67 of the KMEMA is in essence the provision of public goods since it is a precautionary or preventive measure for the efficient performance of oil spill cleaning up. Also the obligation to control marine pollution and the duty to arrange of anti-pollution measures imposed on polluters is the obligation imposed by the public law in accordance with "the Polluter-Pays Principle". Therefore, the execution of such obligations shall be accompanied by the minimum legal and institutional arrangements. On the other hand, judging whether to form the roles of the public and private sectors in providing public goods is basically a matter of policy decision. However, even if the private sector is allowed to participate in the provision of public goods, it is imperative that a minimum requirement be provided to secure the public interest. Although major countries allows polluters to conclude a preliminary contract with a civil anti-pollution management company, these civilian institutions are in principle constituted by the owners of oil storage facilities. Additionally it is worth noting that it operates as a non-profit organization. In particular, if the practitioner performs pollution control for commercial purposes, their profitability may depend on the size of the pollution, the period spent on pollution control, the size of the equipment and manpower mobilized in the pollution control, and so on. Considering the above problems, caution should be taken to allow marine environmental management companies to be un-limitedly entrusted with the responsibility of arranging measures such as pollution control. In order to allow the marine environmental management contractor to be entrusted for the assignment of duty to protect the marine environment, the marine environment management business should be expanded so that the marine pollutant management capacity satisfies the statutory control capacity. For this purpose, it is necessary to manage and supervise the maintenance and improvement of the control capability of the marine environment management business. It is also necessary to discuss the introduction of the grading system for the control ability of the civil control companies alike in major countries.

The purpose of this document is to explain the revisions of the Protection of Cultural Properties Act and its sub-laws which have been mad from Jan. 1999 to Sep. 2001. The Protection of Cultural Properties Act and its sub-laws have been revised three times from 1999 to 2001, before and after the Office of Cultural Properties was raised to Cultural Properties Administration on May 24, 1999. The main points of the revisions are as follows. First of all, the role of the local autonomous entities has been increased. The governor of the local autonomous entities is entitled to announce administrative orders related to the preservation of State-designated Cultural Properties. Also, the local autonomous entities has the authorities to examine whether the construction work which will be made in the outer boundaries, which is provided by regulations, of the protected area of the cultural properties might have any effect on preservation of cultural properties or not. Second, preventive actions to protect the cultural properties have been strengthened. If the scale of construction work is more than some scale, the preliminary survey of the surface of the earth to confirm the existence of buried cultural properties and their distribution is obligated. One who is promoting the development plan more than some scale must discuss the plan with the Administrator of Cultural Properties Administration in the process of planning. These actions would be effective to prevent the cultural properties from being damaged because of the development. Third, relaxation of the restrictions has been proceeded. On the basis of regulations which specify the actions to affect the preservation of cultural properties, negative system that does not limit the actions which are not specified in the regulations is introduced. The appropriateness of both protected structure and area should be regularly reviewed and adjusted. Also, most of the restrictions which was made only for administrative convenience and over-regulated the people's living have been revised. Finally, the number of cultural properties to be protected has been increased. Besides the State-designated Cultural Properties, the other cultural properties which are worthy to be protected as City-or-Province-designated Cultural Properties can be designated provisionally and protected. The system of registration and maintenance of the buildings and facilities which are not designated as the Modern Cultural Heritages is established. The penalty for damaging and stealing the cultural Properties which are not designated to be protected was strengthened. Even a dead natural monument can be acknowledged as an natural monument and it is limited to make a specimen or stuffing of the dead natural monument. All of these actions are fit to the high level of understanding of the public about the cultural properties and as the result of these actions, the number of cultural properties to be preserved has been increased. To sum up, the directions of revisions of the Protection of Cultural Properties Act and its sub­laws which have been made from Jan. 1999 to Sep. 2001. are the localization of the protection of the cultural properties, the strengthening of protective actions, the relaxation of various regulations and the increasing of the number fo the protected cultural properties. Also, various problems raised in the processes of implementations of the laws have been reviewed and revised.

In this study, the correlation between the damage type and operating conditions of the sleepers was analyzed based on the design data and visual inspection results for the concrete sleepers of the sleeper floating track (STEDEF) that have been in operation for more than 20 years. It appeared in the form of cracks, breakages, and breaks in the concrete at the center and tie bar contact and buried areas. As a result of the numerical analysis, it was analyzed that the change in the left and right spring stiffness of the sleeper resilience pad increases the maximum stress, tensile stress, compressive stress, and displacement of the concrete sleeper, and stress concentration in the concrete at the tie bar contact area. It was proved analytically that the sleeper resilience pad can affect the damage of the concrete sleeper. Therefore, damage of concrete sleepers in the sleeper floating track in urban transit could be caused by changes in spring stiffness of sleeper resilience pads. It was reviewed that preventive maintenance such as improvement and timely replacement of sleeper resilience pads was necessary.

This study aimed to investigate the association between plant protein intake and health-related quality of life (HRQoL) in Korean individuals aged 50 years or older. Using the 2016-2018 Korea National Health and Nutrition Examination Survey data, 7,956 participants (3,434 men and 4,522 women) were included in the study. HRQoL was measured using the Euro-quality of life five-dimension (EQ5D), composed of physical function, self-care, daily activities, pain/discomfort, and anxiety/depression problems. The EQ5D estimates were converted into an EQ5D index score. The association between daily intake of plant proteins and HRQoL was evaluated using regression analysis. The intake of total plant protein, legume nut seed (LNS), and fermented bean (FERMB) proteins were all positively associated with HRQoL in both men and women (p < 0.01). Of EQ5D's five dimensions, physical function and daily activities were most commonly associated with plant protein intake. Compared to LNS protein or FERMB protein intake, total plant protein intake showed a better association with HRQoL. In conclusion, a significant association was observed between plant protein intake and HRQoL. It suggests that adequate intake of plant protein might be helpful for the maintenance or improvement of HRQoL in Korean adults.

Objectives: The purpose of this study was to analyze the influence of four lifestyle-related diseases, diabetes, hypertension, obesity and hypercholesterolemia, on oral health in the rural elderly in Korea. Methods: We enrolled 399 subjects over 60 years of age over a six year period, year 2000-2006/ year 2001-2007. All subjects received a routine health examination as part of a program conducted by the National Health Insurance Corporation at Seongju-gun Public Health Center in Gyeongsangbuk-do Province, South Korea. All subjects were surveyed and examined to determine their general and oral health statuses. Results: Our results suggest that the duration of lifestyle-related diseases has a significant influence on oral health. The following factors were all significant in the results of analyses: duration of diabetes, tooth decay, which teeth had decayed, missing and filled teeth(DMFT), duration of hypertension, and duration of obesity and hypercholesterolemia(p<0.05). Our results also suggest that the number of lifestyle related diseases has a significant influence on oral health. Subjects with more than two diseases had significantly greater numbers of missing teeth and greater numbers of DMFT(p<0.01). The results of simple regression analysis indicate that patients exhibiting longer durations of diabetes also exhibit more tooth decay, and that patients exhibiting longer durations of hypertension and obesity are characterized by greater numbers of missing teeth. The longer the duration of any of the four lifestyle-related diseases we considered, the more DMFT we observed. Multiple regression analyses also demonstrated that longer duration of lifestyle-related disease was associated with greater numbers of missing teeth. As the number of lifestyle-related diseases increased, DMFT also increased. Conclusions: In summary, lifestyle-related diseases such as diabetes, hypertension, obesity and hypercholesterolemia have significant influences on oral health in the elderly. In this context, the prevention and management of lifestyle-related disease is critical for the maintenance and promotion of oral health.

A total health state evaluation of Korean female elderlies was made by using the questionary scheme measuring the physical, mental and social functions of the elderlies, in order to investigate the critical factors for the health maintenance of female elderlies and to develop their preventive nursing program. A total of 280 subjects over 65 years old living in Seoul and the suburban area were selected and interviewed during the period of September and October in 1995. The materials collected were analyzed statistically by using SAS data processing program, and the results and recommendations are summarized as follows. 1. The physical health state of Korean elderly women was evaluated to be satisfactory by showing an average score of 3.722 in 5.0 full-score scale. But this score was lower than those evaluated for the elderlies combined both sexes(4.054). The mental health state of the subjects was also evaluated as high scoring 3.484, possibly due to the fact that 78% of the subjects lived together with their children's family. On the other hand, the social health state of the subjects was relatively low scoring 2.585, mainly due to that 80% of them was widows which was resulted by the 6-7 years longer life-expectancy of Korean women. 2. A significant differences in the physical health state scores between different age groups was observed, indicating the rapid ageing process occurring in this age group. The family structure was appeared to be an important factor influencing the physical health state of the female elderlies ; the physical health score of the women with her husband only was higher than that of those living with children's families, and the lowest score was obtained from those living alone. 3. The age was the most important factor determining the mental health state of the subjects, while the religion, educational status, marriage state and family structure did not significantly influenced the mental health state of the aged women. 4. The social health state of the subject was deeply influenced by the marriage state and family structure, showing significantly lower scores with widowers compared to the married couples. Those living with their married spouse only obtained the highest social health score, while those living along showed the lowest score. The parent and grandparentship of those living with their children and the religion, especially Catholic and Protestant, had positive influence on the social health state of the aged women. 5. The mental health state of aged women showed significant correlation with the factors determining the physical health, except for digestive system related ability and sexual ability and the highest extra home ability. 6. The mental health state of aged women showed significant correlation with the factors determining social health, especially with the parent and grandparentship and the family relative's role. From these results, the following recommendations are made. 1. Since the physical, mental and social health states of aged people are deeply influenced by the sex and the average values of the both sex can create misleading figures, the health evaluation of the elderlies should be made separately by sex. 2. Since the health state of aged women is highly influenced by their family structure, the spouse's role and living with married couple only should be emphasized in respect of preventive health care. 3. The social activity programs and grandparentship teaching programs should be prepared in the nursing care program for aged people.

Objectives: The present study aimed to provide the fundamental data for guiding establishment of measures among the rural elderly population with physical disabilities. The specific goals of this report are to reveal the prevalence of their disabilities, its tendency according to their increasing age, and to assess the background explanations. Methods: The self-administered questionnaires have been performed 432 persons of rural residents age 40 and greater in Kumsan-Gun and Chongyang-Gun, Chungchongnamdo Province. The questionnaire items included presence or not. of disabilities. specific causes for disabilities, anthropometric measures, and amount of physical activities. Results: The proportion of disabilities was higher in women than men, and the functional degree of their limbs decreased with the increasing age. The proportion of disabling extremities was higher in the lower extremities than in the upper ones. Joint diseases were the most prevalent causes for disabilities of extremities. Concerning the degree of depression, 41.2% of study subjects were normal, 47.5% had mild depression, 6.3% moderate, and 5.1% severe depression, with no statistical difference based on age and sex. The worse are the functional degree of both extremities, the greater the degree of depression the subjects had. The odds ratio for presence of disabilities of extremities was 2.6 times higher in women than in men for sex and for age, 50's were 3.5 times, 60's 4.3 times, 70's 4.9 times than 40's, respectively, with increasing tendency with increasing age. The odds ratio for depression was 1.2 times greater in subjects with disabilities than in normal population with no statistical difference. Conclusions: More efforts are needed to establish elderly specific measures for providing proper public health services centering on maintenance of physical functioning among elderly population.

Wooden architectural cultural heritages are one of the visible legacies that show the national's identity. Even when the concept of 'the original' of cultural heritages was not accurately understood, the emphasis of preservation and management of cultural heritages was placed on 'preservation of the original form' or 'maintenance of the original form'. Moreover, these days, following the trend of international preservation principles, cultural heritages are considered important as "values as historical objects." This paper is the result of an attempt to determine the scope and content of what parts should be monitored to maintain the original form of wooden architectural cultural heritage. The first thing to be done in monitoring wooden architectural cultural heritage is to check the condition of the ground and foundation. The second is the column. This is because the instability of the column causes damage to the joint with each member and the fitting part, resulting in physical changes leading to damage to the wall. The third is monitor the roof tiles. If the leak continues into the building due to the separation or damage of the roof, the defect should be partially dismantled and repaired, so it should be monitored to maintain its original shape as much as possible. The monitoring range of the base, column, and roof serves as a reference point for identifying what damage is being done to the relevant cultural heritages. In other words, the data at the time when monitoring began becomes the 'original' for the year. Alternatives based on the analysis of monitoring for the preservation of original cultural heritages should be actively introduced. In addition, by sharing the current state and situation of cultural heritages as a result of monitoring with various related organizations, preventive preservation should be established rather than preservation of cultural heritages by "intervention."

The five-story and seven-story stone pagodas at Cheongnyangsaji temple site in Gongju are located under the Sambulbong peak of Gyeryongsan mountain, and are known to have been built of the middle in Goryeo dynasty. As the two pagodas in which two types of Baekje stone pagoda coexist in one era, their historical and academic value are recognized. The seven-story pagoda was overturned by robbery in 1944, and as a result, the five-story pagoda was tilted. Although the two pagodas were restored in 1961, structural instability was continuously raised. In this study, measurement data accumulated from May 2021 to March 2022, and seasonal characteristics were reviewed, and the micro behavior of pagodas were analyzed according to temperature and precipitation during the same period. As a result, the micro thermoelastic behavior was repeated according to the daily temperature change in all sensors, and both the slope and the displacement showed microscale behavior. In the inclinometer, moisture containing the surface and inside of the stones repeated expansion and contraction due to temperature change, showing the micro movements. In particular, the upper part of the five-story pagoda moved up to 3.89° to the northwest, and the seven-story pagoda tilted up to 0.078° to the northeast. The maximum displacements were recorded as 0.127 and 0.149 mm in the five-story and the seven-story pagoda, respectively. These values tended to return to the original position at the end of the measurement, but did not recover completely, indicating a state requiring precise monitoring. The result obtained through the study can be used as basic data for the stable conservation of the two stone pagodas. Based on the behavioral characteristics considering various environmental factors should be analyzed, and the preventive conservation through the maintenance of measurement system built this time should be continued.
