1,4-dioxane and dichloromethane are classified as carcinogenic groups in the International Agency for Research on Cancer (IARC). They are frequently released at high concentrations in an industrial wastewater effluent. The acute toxicity (24 h) of Daphnia magna for 7.53 mg/L of 1,4-dioxane in the industrial effluent was evaluated as 1.1 TU (toxic unit) and showed TU close to the effluent quality standard. Mixed substances of 1,4-dioxane and dichloromethane in the industrial effluent showed relatively high TU as compared to that of a single substance. Half maximal effective concentration (24 h $EC_{50}$) values of 1,4-dioxane and dichloromethane for the synthetic wastewater prepared in laboratory were 1,744 (0.06 TU) and 170 mg/L (0.6 TU), respectively and the toxicity was low. Nevertheless the toxicological evaluation of the mixture showed that TU values increased to 0.02, 0.04 and 0.10, respectively as 1, 5 and 10 ppm of dichloromethane was added to 100 ppm of 1,4-dioxane. And the synergistic effect was observed between two substances. But the TU value of synthetic wastewater was below 5%, lower than that of industrial effluent at the similar concentration.

Unlike benign tumors, malignant tumors are capable of metastasis, easy to relapse, poor survival, and low quality of life. In Korea, here is a tendency to treat the tumors collectively according to the General Principles of Cancer Chemotherapy(GPCC) of the Health Insurance Review & Assessment Service (HIRA). But recently, companion diagnostics(CDx) is recommended rather than unilateral medication because biomarker-based molecular diagnostics is possible to predict the drug response of patients before drug treatment. Not only domestic but also overseas Food and Drug Administratio (FDA) recommends the development of the CDx system at the stage of drug development to ensure the responsiveness and safety of medicines. In this study, I focused on the necessity of CDx development direction as well as CDx development status through literature review. Furthermore I also discussed CDx types according to the molecular diagnostic technology such as immunohistochemistry (IHC), polymerase chain reaction (PCR), in situ hybridization (ISH), and next-generation sequencing (NGS) not only in the approved CDx but also in the developing one by US FDA. And I suggested the technology issue of CDx development process such as a selection of molecular diagnostics at the time of release, a clear understanding of the CDx mechanism, and a convergence of drug with CDx development. The necessity of social insurance system also was proposed for CDx development.

The Records Management Act was established by the result of the National Archive reformism in 1999. However, it could not have brought high-quality changes of recording management since recording management innovation was not continuously achieved. On the other hand, in 2006 the Records Management Act was completely revised as a part of recording management innovation. The records management innovation road map is created as an agenda in order to accommodate difficulties we face in the process of the records management reformism and to establish a norm in accord with international standards, a redesign of records management process and a development of records management system so that it can react quickly to rapidly changing situations on records management paradigms. The organization of the Records Management Act was revised by compensating the defect and applying in international standards. This is due to the fact that it is the highest priority assignment to be able to help promote those sorts of innovation to provide an institutional strategy. 'The National Records Management Advancement Strategy' of National Archives in 2009 seems to be an extension of the recording management Innovation road map. Nonetheless, this strategy cannot be considered a strategy of the consecutive national records management reform since it reflects the basis of the existing policy without any assessment with respect to the records management innovation. Government-level talks on records management innovation should be regarded so as to establish a national policy on records management and to be consistent in carrying Out the policy. This research focuses on how the records management innovation road map is reflected in the Records Management Act in 2006 and how international standards are applied in the act in the national records management regime and current records management system. Furthermore, several challenges will be illustrated to overcome a limit of the Records Management Act in the process.

This study focuses on the sleep pattern of the elderly people living in the community and its relationship to the occurrences of the depression and deterioration of the cognitive function. Our primary data is the raw data gathered by the Korean Ministry of Health and Welfare in 2008 in the National Senior Living Conditions and Well-being Needs Assessment Survey. The survey contained data from 12,087 people over 65 years of age living in the community. We have used the secondary data analysis method on this raw data to see if there exists correlation between age, gender, soundness of the sleep, total sleep time and the depression and the cognitive difficulties. Our study finds that the older a person is, the more trouble she has in sleeping. It also shows that too much sleep (in excess of 9 hours) and too little sleep (less than 6 hours) can both be linked to more occurrence of depression. Lack of restful sleep could also be linked to more frequent occurrence of depression and cognitive difficulties. Changes in the sleep pattern is not always pathological in elderly people. However, our study shows that it is important the primary health-care givers understand the role of sleep in elderly person's daily life. They should examine the elderly person's sleep pattern focusing on the quantity and the quality of sleep and develop programs suited for individuals to prevent and intervene sleep disorder.

A Visual landscape planning and management system has been introduced and implemented by each ministry so as to solve the problems of visual landscape destruction due to recognition on the value of natural landscape of beautiful territory and various development projects. At present, this system emphasizes the importance of the visual and perceptual aspect of the landscape however, there is a lack of techniques required for comprehensively predicting, evaluating, and managing it. Furthermore, sustainable landscape management after the completion of development projects has been inadequately carried out, as the focus has been only on consultation in the planning process of the development project in institutional performance. To this end, we presented objective and standardized criteria to predict and judge the effects of development projects on landscapes before project implementation. During the implementation of the development project, the influence of the visual landscape becomes accumulated in the construction progress stage. There is a need to identify the main viewpoints and to examine the continuous changes in the landscape-influencing factors, owing to the remarkable influences on the landscape, such as the change in the topography and the change caused by the artificial structure. During the stage of managing the influence on the visual landscape after the completion of the project, the influence on landscape should be monitored by measuring the change in the continuous landscape-influencing factors and determining the extent to which the actual reduction plan has been implemented. These processes should be performed continuously to maintain the quality of the visual landscape. The change in the landscape caused by the development project is shown to cause relatively greater visual damage than other factors composing the landscape owing to the influence of the artificial factors including the structure or the building. This shows that not only detailed examination of the visual impact before the development project but also continuous management is required during and after the development project. For this purpose, we derived eight landscape-influencing factors including form/shape, line, color, texture, scale/volume, height, skyline, and landscape control point. The proposed considering to be of high utilization in that it has a clear target of the landscape influencing factors.

As the social interest of the Baby Boomer generation is increasing, this study derives implications for lifelong education policy through identification of the need and support for lifelong education among baby boomers lifelong learning, taking into account such aspects of quality of life as emotional psychology-based self-development and self-realization. To optimally explore support for lifelong learning for the baby-boomer generation, first-tier (top-level), sixth-tier (bottom-level), and five-other evaluation criteria were available. For the first layer, we examined whether potentiality or realizability was more desirable, and for the second layer, detailed criteria for realizability were set up, dividing them into financial, legal, and administrative feasibility. A study conducted by experts on the policy priority analysis of Baby Boomers showed that their support for lifelong learning places a greater priority on its feasibility (the more feasible alternative) than desire (the more desirable option). Among the six criteria, lifestyle activities had high priority, and the relative importance of the five assessment alternatives for lifetime learning activities was shown to be higher for employment skills education (0.377), civil participation education (0.181), lifestyle activities (0.200), and 'lifetime activities' (06.11). These results are meaningful: they can help shape and refine the needs of lifelong education, assess their relative importance, and prepare basic data for lifelong learning policies for baby boomers who are about to enter their old age.

This study examines the effect of thinning in terms of changes in the growth characteristics of Chamaecyparis obtusa stands after they were thinned with varying intensity in Gochang, North Jeolla Province, Korea. Thinning was carried out in 2000 on Chamaecyparis obtusa stands (22 years old), and the stands were categorized in terms of the thinning intensity in the experiment: very heavy, heavy, medium, light, and control. The results of monitoring up to 2018 revealed that the diameter at breast height and the growth rate of individual trees after thinning had a positive correlation with the thinning intensity, whereas the stand volume showed a negative correlation. The height to diameter (H/D) ratio decreased by up to 70-80 due to the increased diameter at breast height after thinning and thereby resulted in better quality. The relative yield index right after the first thinning was between 0.75 and 0.95, which suggests the best timing for the first thinning had been missed. This study's findings are expected to serve as a basic reference in establishing the thinning system for Chamaecyparis obtusa forests.

Sustainable development in society has become the center of focus in many fields such as industry, environment, health, culture, etc. Considering that the concept of heritage involves understanding it as a 'resource' to improve the quality of people's lives, sustainability is an important goal that heritage policy has to achieve. Adopting the definition of sustainability in the 1987 Brundtland Report, this paper defines the concept of sustainability with respect to heritage, as well as their respective roles. Following that, three action principles are presented: value-based conservation, rational decision-making, and community involvement. Two cases demonstrating how the three principles should be practiced in managing change are then illustrated. Considering that heritage can play its role as a resource once its significance is protected, this paper argues that value-based rational decision-making is of paramount importance and the first principle. Conservation aims to manage change by practicing a cyclic process of value identification, value sustaining, and value dissemination. Therefore, this paper argues that all processes should be connected in the context of heritage values. A rational decision-making process practicing value-based conservation is then suggested. This paper argues that rational decision-making can only be practiced once values are identified by objective criteria and managed by rational judgment upon impact assessment. Community involvement, the third principle, is necessary to realize value-based conservation and rational decision-making. Recognizing that a community is a beneficiary of heritage and a creator of a beneficial process at the same time, it discusses the role of community and the importance of this role in policies for the sustainability of heritage. This paper concludes with a set of recommendations to improve policies after examining the two decision-making cases.
