This study aims to identify the relationship between termite-damaged cultural heritage sites and the 'Forest Tending Project' based on a comprehensive survey of the status of damage caused by termites and of the Forest Tending Project. It was observed that the Forest Tending Project started in 2004 as a five-year policy project covering over 59% of the nation's forests, which showed the maximum value in 2009 and then gradually decreased. Since then, increased damage to national cultural heritage sites by termites has been confirmed and counter measures have been expanded since 2012. Also, as a result of the National Research Institute of Cultural Heritage surveying the status of termite damage in national cultural heritage sites over these six years, it was identified that about 98% of investigated cultural heritage sites were damaged by termites, about 78% of them were adjacent to forests, and that all 46 national cultural heritage sites which had been included in the 2008 Forest Fire Prevention Cultural Heritage Afforestation Project were damaged by termites. Therefore, it is claimed that the number of termite-damaged cultural heritage sites has increased after an extensive Forest Tending Project was applied on a national scale, and it seems that all cultural heritage areas close to forests are particularly subject to termite-damage due to the number of tree stumps and lumber byproducts which can serve as habitats for the pests.

The purpose of this study is to analyze the current status of counter terrorism system and to identify the causes of problems and to suggest alternatives by selecting legal and operational sectors based on theories of open systems and integrated systems. According to the results of the research, first, the degree of agreement on the open system and the integrated system is low with regard to the characteristics of the counter-terrorism system. Second, in relation to the importance and necessity of major factors of construction and operation of counter-terrorism system, counter-terrorism workers recognize that it is the most important and necessary. In the case of strengthening international cooperative system, the difference of recognition between importance and necessity was the biggest. The importance and necessity of reviewing the Anti-Terrorism Act for the protection of the public and public safety were relatively low, and the cooperation with the private sector showed the lowest importance and necessity. In the case of academic achievement, the average level of high school graduates is higher than that of professional high school graduates. Therefore, this research concludes that counter terrorism operation system with open and integrated system has to be applied to national counter terrorism operation structure in South Korea in increasing the quality and efficiency of nation counter terrorism response capability.

This study aims to analyze gender differences in the prevalence of and risk factors for self-neglect among the elderly in South Korea. In order to investigate the differences between male and female elderly group, we compared 793 elderly men and 1,089 women from the data "Research on the Healthy Aging and Well-being of the Elderly" conducted in 2018. First, t-test and ${\chi}^2$-test and multiple regression analysis identified that gender differences in the prevalence of elder self-neglect was not statistically significant. Second, There are differences in risk factors affecting self-neglect between genders. age and class(perception) are the factors only affecting men. Income(monthly), having-religion, living-alone, satisfaction with life, social network are the ones only affecting women. Third, the risk factors for both men and women are depression and social support(public support). It is notable that we verify the empirical evidence supporting the hypothesis that risk factors for elder self-neglect may exist differently according to gender. In particular, gender characteristics revealed in this study can be reasonably explained through exchange theory and feminist theory. Therefore, we emphasize that the policy approach should be done depending on the gender of the elderly, and that the social safety net more paying attention to the depression of the elderly should be strengthened.

This study aimed to discuss mental health services for children and adolescents that are being implemented as initiatives of the Korean government and to review the functions and roles of these projects during the COVID-19 pandemic. Three government departments are in charge of providing mental health services for children and adolescents: Ministry of Education, Ministry of Gender Equality and Family, and Ministry of Health and Welfare. The Ministry of Education has implemented several policies to facilitate the early detection of mental health issues among school students (from preventive interventions to selective interventions for high-risk students). The Ministry of Gender Equality and Family additionally serves out-of-school children and adolescents by facilitating early identification of adolescents in crises and providing temporary protection or emergency assistance (as required) through the Community Youth Safety-Net Project. Furthermore, the Ministry of Health and Welfare operates relevant mental health agencies for individuals of all ages including children and adolescents. Any high-risk students who have been screened through the projects of the Ministry of Education are supported through referrals to the following institutions for appropriate treatment of their symptoms: specialized hospitals, the Youth Counseling and Welfare Center operated by the Ministry of Gender Equality and Family, the National Youth Healing Center, the Mental Health Welfare Center operated by the Ministry of Health and Welfare, the Suicide Prevention Center, and the Child Welfare Center. To assist students who are facing any psychological difficulties because of the COVID-19 pandemic, the Ministry of Education has established a psychiatric support group for providing emergency mental health care; furthermore, schools are promoting psychological surveillance (e.g., provision of non-face-to-face counseling services that are centered around the Wee Center). The Ministry of Education, Ministry of Gender Equality and Family, and Ministry of Health and Welfare have provided varied mental health support services in order to address the challenges faced by children and adolescents during the pandemic. Nevertheless, the mental health services operated by each ministry do show some limitations because their service provision system is insufficiently collaborative. The present study discussed the positive effects of each initiative as well as its limitations; furthermore, it suggested improvements for facilitating the healthy development of children and adolescents' mental health.

Autonomous driving technology is shaping the future of personalized travel, encouraging personalized travel, and traffic impact could be influenced by individualized travel behavior during the transition of driving entity from human to machine. In order to evaluate traffic impact, it is necessary to estimate the total number of trips based on an understanding of individual travel characteristics. The Activity-based model(ABM), which allows for the reflection of individual travel characteristics, deals with all travel sequences of an individual. Understanding the relationship between travel and travel must be important for assessing traffic impact using ABM. However, the ABM has a limitation in the data hunger model. It is difficult to adjust in the actual demand forecasting. Therefore, we utilized a Tour-based model that can explain the relationship between travels based on household travel survey data instead. After that, vehicle registration and population data were used for correction. The result showed that, compared to the KTDB one, the traffic generation exhibited a 13% increase in total trips and approximately 9% reduction in working trips, valid within an acceptable margin of error. As a result, it can be used as a generation correction method based on Tour, which can reflect individual travel characteristics, prior to building an activity-based model to predict demand due to the introduction of autonomous vehicles in terms of road operation, which is the ultimate goal of this study.

Spread of pathogenic micro-organisms through contaminated hands is a well recognized way of transmitting disease such as food poisoning. We investigated the prevalence of aerobic plate counts, coliform bacteria, and food-poisoning bacteria on hands in various age groups. The average number of aerobic plate counts was 3.3 log CFU/hand in kindergarteners, 3.4 log CFU/hand in elementary students, 3.2 log CFU/hand in middle school students, 3.4 log CFU/hand in high school students, and 3.3 log CFU/hand in adults. Two kindergarteners, 6 elementary students, and 2 adults were positive for the coliform bacteria. Among the food poisoning bacteria we tested, S. aureus was isolated from 47 individuals. Eight isolates of B cereus were all from kindergarteners. C. perfringens was isolated from 7 individuals. Among 47 isolates of S. aureus, 25 isolates produced toxins. Seven of eight isolates of B. cereus produced toxins. None of seven C. peifringens isolates produced toxins. All 47 isolates of S. aureus were sensitive to ciprofloxacin, trimethoprim/sulfamethoxazole, clindamyccin, imipenem, rifampin and vancomycin. Four isolates (8.5%) were resistant to cefepime, chloramphenicol, cefotetan, and gentamycin. Five isolates (10.6%) were resistant to oxacillin and 6 isolates were resistant to tetracycline. This study shows that it is needs to be established policy of school lunch and personal sanitation management.

The purpose of this study was to determine obstructive factors and performance level of the HACCP system among elementary schools in Gyeongbuk province. E-mail survey targeted 320 dieticians, and recovery rate was 74.1%. Consequently, 227 responses were analyzed. The questionnaire was composed of 58 items under four sections (general characteristics, dieticians' perceived HACCP performance level, dieticians' perceived CCP performance level, and obstructive factors of HACCP system implementation). The item with the highest rate of HACCP performance level was 'HACCP training for foodservice employees in schools ($4.02{\pm}0.70$)' while the lowest counterpart was 'implementation of HACCP team meeting, reporting, and maintenance ($2.74{\pm}0.99$)'. The performance level of the item 'HACCP training for foodservice employees in schools' was perceived as highest when the number of students eating school meals was greater than 1,101 (P<0.05). Moreover, CCP 4 ($4.44{\pm}0.53$) and CP 5 ($4.44{\pm}0.51$) showed the best performance, whereas CCP 1 showed the lowest performance level ($3.90{\pm}0.60$). Therefore, reinforcement of hygiene instruction in menu planning is perceived as necessary. CCP 1, CCP 6 (P<0.05), and CCP 3 (P<0.001) showed significant differences in performance based on the number of students eating school meals. Further, according to results regarding obstructive factors of HACCP system execution, 'general factor' was the most severe obstructive factor in the application of HACCP ($3.46{\pm}0.62$). Among the 'factors pertaining to dieticians', the item 'hardship of proper monitoring and micro-management due to overwhelming workload' was most influential ($3.46{\pm}0.96$). Furthermore, the item 'low budget allocation by educational offices ($3.90{\pm}0.88$)' was influential among the 'factors pertaining to school administrations'. In conclusion, the results of this research can help solve obstructive factors of elementary school food services and provide knowledge that is essential for the proper implementation of HACCP.

International Civil Aviation Convention contracted in 1944 adopted International Standards and Recommended Practices(SARPs) as Annexes to Convention for safety and order of International Air Transport and each contracting State shall establish and amend the law on the basis of the SAPRs. However, Any State which find it impracticable to comply in all respects with any such SARPs, or which deems it necessary to adopt regulations or practices differing in any particular respect from those established by SARPs shall give immediate notification to the ICAO of the differences between its own practice and that established by the SARPs and ICAO publish these difference notices as a supplement to annexes. Korea and neighboring countries contracting States with International Civil Aviation Convention are accomplishing standardization of regulation on the basis of SARPs in each State. Air Law of each State need to study on the trait and differences for safety of frequent air transport services around the Korean Peninsula, However, because Korea and Neighboring countries have differences of Air Law by reason of cultural differences and circumstance of each State. Korea and Neighboring countries mean Republic of Korea, The People's Republic of China, Japan and The Domestic People's Republic of Korea and study on Air Law of each state in this study. One of purposes of this study is to analyze the history and organization of each state and then to review how establishing own air law affect air law of each state. Another purpose is to make comparative study on differences between own regulation in Korea and neighboring countries and SARPs and then to review how the differences notice of each state affect air law of each state.

Last 50 years there were a lot of space subjects launched by space activities of many states and these activities also had created tremendous, significant space debris contaminating the environment of outer space. The large number of space debris which are surrounding the earth have the serious possibilities of destroying a satellite or causing huge threat to the space vehicles. For example, Chinese anti-satellite missile test was conducted by China on January 11, 2007. As a consequence a Chinese weather satellite was destroyed by a kinetic kill vehicle traveling with a speed of 8 km/s in the opposite direction. Anti-satellite missile tests like this,contribute to the formation of enormous orbital space debris which can remain in orbit for many years and could interfere with future space activity (Kessler Syndrome). The test is the largest recorded creation of space debris in history with at least 2,317 pieces of trackable size (golf ball size and larger) and an estimated 150,000 debris particles and more. Several nations responded negatively to the test and highlighted the serious consequences of engaging in the militarization of space. The timing and occasion aroused the suspicion of its demonstration of anti-satellite (ASAT) capabilities following the Chinese test of an ASAT system in 2007 destroying a satellite but creating significant space debris. Therefore this breakup seemed to serve as a momentum of the UN Space Debris Mitigation Guidelines and the background of the EU initiatives for the International Code of Conduct for Outer Space Activities. The UN Space Debris Mitigation Guidelines thus adopted contain many technical elements that all the States involved in the outer space activities are expected to observe to produce least space debris from the moment of design of their launchers and satellites until the end of satellite life. Although the norms are on the voluntary basis which is normal in the current international space law environment where any attempt to formulate binding international rules has to face opposition and sometimes unnecessary screening from many corners of numerous countries. Nevertheless, because of common concerns of space-faring countries, the Guidelines could be adopted smoothly and are believed faithfully followed by most countries. It is a rare success story of international cooperation in the area of outer space. The EU has proposed an International Code of Conduct for Outer Space Activities as a transparency and confidence-building measure. It is designed to enhance the safety, security and sustainability of activities in outer space. The purpose of the Code to reduce the space debris, to allow exchange of the information on the space activities, and to protect the space objects through safety and security. Of the space issues, the space debris reduction and the space traffic management require some urgent attention. But the current legal instruments of the outer space do not have any binding rules to be applied thereto despite the incresing activities on the outer space. We need to start somewhere sometime soon before it's too late with the chaotic situation. In this article, with a view point of this problem, focused on the the Chinese test of an ASAT system in 2007 destroying a satellite but creating significant space debris and tried to analyse the issues of space debris reduction.

Background : Ambient particles during Asian dust events are usually sized less than $10{\mu}m$, known to be associated with the adverse effects on the general populations. But, there has been no considerable evidence linking these particles to the adverse effects on airways. The objectives of this study was to investigate the possible adverse effects of Asian dust events on respiratory function and symptoms in subjects with bronchial asthma. Patients and Methods : From march to June 2002, Asthmatic patients who were diagnosed with bronchial challenge test or bronchodilator response were enrolled. We divided them into three groups; mild, moderate, and severe, according to the severity. Subjects with other organ insufficiency such as heart, kidney, liver, and malignancy were excluded. All patients completed twice daily diaries and recorded peak flow rate, respiratory symptom, and daily activity. Daily and hourly mean pollutant levels of particulate matter < $10{\mu}m$ in diameter($PM_{10}$), nitrogen dioxide($NO_2$), sulphur dioxide($SO_2$), ozone($O_3$) and carbon monoxide(CO) were measured at the 10 different monitoring sites. Results : Dust events occured 14 times during the study period. Daily averages of 4 air pollutant were measured with an increased level of $PM_{10}$, decreased level of $NO_2$ and $SO_2$, and no change in CO during dust days compared to those during control days. An increase in $PM_{10}$ concentration was associated with an increase of subjects with PEF variability of >20% (p<0.05), night time symptom(p<0.05), and a decrease in mean PEF (p<0.05), which were calculated by the longitudinal data analysis. Otherwise, there was no association between $PM_{10}$ level and bronchodialtor inhaler, and daytime respiratory symptoms. Conclusion : This study shows evidence that ambient air pollution, especially $PM_{10}$, during Asian dust events, could be one of the many aggravating factors at least in patients with airway diseases. This data can be used as a primary source to set up a new policy on air environmental control and to evaluate the safety of air pollution index. We also expect that this research will help identify precise components of dust, which are more linked to the adverse effects.
