Introduction of TBELs into Korean environmental regulatory system for wastewater may require very careful considerations and appropriate modifications of the TBELs applied in US. The Korean regulations for wastewater are based on uniform regulatory criteria for wastewater effluent discharge and are quite different from the individual permit system in US. In addition, the toxic pollutants regulated in Korea are much less than those in US. Therefore, the effects of TBELs application on the pollutants reduction and the economic feasibility should be carefully assessed for different categories of wastewater sources. In this study, the applicability of TBELs for the industrial categories of Korea was discussed. The TBELs were derived for a sample category, the pulp paper paperboard manufacture, based on the previously reported analytical data from 52 facilities of the domestic pulp paper paperboard manufacture in Korea. It was suggested that the BAT effluent limitations were BOD 30 mg/L, $COD_{Mn}$ 40 mg/L, SS 40 mg/L, T-N 30 mg/L and T-P 4 mg/L and that the allowable effluent loads were $0.31{\sim}1.75kgCOD_{Mn}/ton$-products. Due to the limitation of insufficient data, there were difficult to obtain the important factors to derive more systematic and accurate limitation standards for the pollutants such as the 'Long Term Average (LTA)', the 'Product Normalized Discharge Flow (PNDF)', and the 'Variability Factor (VF)'. However, as the first trial of TBELs determination based on the all available analytical data reported, the procedure and the outcome of the study may provide valuable insight on application of TBELs in Korea.

The purposes of study are to examine early appearance of rural village development that local administration firstly promoted through the 'Mobum Burak Development' promoted in environment change around the local government in 5 16 military government period and find implications of the current rural village development. During the military government period(1961~1963), rural administration showed lots of changes such as reorganization of administration system whose basic local government are si gun, introduction of national planning system and spread of si gun, reorganization of rural taxation system, diversification of extension caused by the establishment of rural facilities such as new Nong-hyup, RDA, etc. Thus, the main axis of development administration of counties was transferred from central government or American aid organization to local administration. According to the basic operation plan introduced after the 5 16 as a planning system, the Ministry of Home Affairs instructed to write and promote gun construction plan based on all conditions of gun as long-term general plan of rural development. Therefore, each do established general plans such as 'Nongdo Jeonbuk Geundaehwa Plan', 'Yakjin Gyeongbuk Plan', 'Jeonnam Miraesang', etc. and Mobum Burak Development was promoted by all kinds of titles such as 'Bogoganeun Maeul(Jeonbuk)', 'Bitnaneun Maeul(Chungnam)', 'Hyeokmyeong Chon(Gyeonggi)', 'Saemaeul geonseol(Gyeongnam)', etc. as a business of rural village development. But, business contents of gun's 'construction plan' couldn't be mutually connected although Mobum Burak Development and unit business contents were promoted by duplicated plan. It became useless general plan as times went by as business focusing on short-term outcomes rather than construction based on long-term region. Mobum Burak Development also borrowed contents community development business, but military government couldn't approach basic solution of village and regional agriculture by focusing on short-term outcome, without imitation of form and procedure. This study is judged to be utilized as basic data of following studies because rural village development companies focusing on national policies discovered unit rural companies and analyzed them by connecting to environment changes of rural administration.

This paper evaluates the effects of the Basic Subsidy Program provided to families with infants cared for in private day care centers. There has been a discrepancy in the price and quality level between public and private day care centers. Public day care centers which receive government support in their labor costs are able to maintain relatively higher quality at lower price than their private counterparts, while the majority of children are cared for at private day care centers. To reduce the gap of the price and quality of care between public and private day care centers by improving the quality and decreasing the price of private day care centers, the Basic Subsidy Program was introduced in 2006 to the private day care centers. The subsidies mainly aim to improve the quality and the accessibility of child care, and encourage mothers' labor supply. For this purpose, the provision of the Basic Subsidy Program imposed prerequisites to the care providers including minimum wage and four major insurances for teachers, and child-staff ratio. I examine whether the subsidies improve the quality of care, help mothers balancing work and family, and increase satisfaction with child care from mothers' perspective. Since the outcome variables that measure the quality of care are difficult to obtain, I instead use the input variables for quality production. Child-staff ratio, teachers' welfare, and care environment are considered. The relationship between these variables and the introduction of subsidies is examined. The 2004 National Survey of Child Care and Education and the 2004 National Survey of Day Care Centers are used for the base data set. To reflect the outcomes after the Basic Subsidy Program, equivalent data sets for households and care providers are constructed by the KDI Data Analysis Unit. Using these nationally representative data sets, information regarding child care is collected. The findings show that the subsidies contribute to the quality of care improving the input variables of quality production. The welfare of teachers is improved, and the child-staff ratio significantly decreases. As a result, the usage of private day care centers greatly increases even though the price level rarely changes. However, mothers' satisfaction with child care are rarely affected by the subsidies. Although the subsidies with no eligibility criteria enlarge the recipients, the actual effects to increase maternal labor supply or to improve satisfaction is limited. Given this findings, I suggest some modifications of subsidies to raise the effectiveness of the subsidy program.

Introduction: Recent studies have shown that circulating tumor cells (CTCs) play potential roles as diagnostic and prognostic biomarkers with various cancer types. The aim of this study was to comprehensively and quantitatively summarize the evidence for the use of CTCs to predict the survival outcome of lung cancer patients. Materials and Methods: Relevant literature was identified using Medline and EMBASE. Patients' clinical characteristics, overall survival (OS) and progression-free survival (PFS) together with CTC positive rates at different time points (before, during and after treatment) were extracted. A meta-analysis was performed to clarify the prognostic role of CTCs and the correlation between the CTC appearance and clinical characteristics. Results: A total of 12 articles containing survival outcomes and clinical characteristics and 15 articles containing only clinical characteristics were included for the global meta-analysis. The hazard ratio (HR) for OS predicted by pro-treatment CTCs was 2.61 [1.82, 3.74], while the HR for PFS was 2.37 [1.41, 3.99]. The HR for OS predicted by post-treatment CTCs was 4.19 [2.92, 6.00], while the HR for PFS was 4.97 [3.05, 8.11]. Subgroup analyses were conducted according to histological classification and detection method. Odds ratio (OR) showed the appearance of pro-treatment CTCs correlated with the lymph node status, distant metastasis, and TNM staging, while post-treatment CTCs correlated with TNM staging only. Conclusion: Detection of CTCs in the peripheral blood indicates a poor prognosis in patients with lung cancer.

Recently EA(Enterprise Architecture) has been receiving growing attentions again from the public sectors. It is because EA maturity result is reflected to the organization's informatization level and EA maturity ratio has been enlarged. There has been more participation from the Chief Information Officers of the public sectors. EA research in the public sectors has influenced IT environment since the research started in late '90, the legislation work done in '05, and the maturity model developed in '06. However, there are some remaining tasks to solve. EA policy is introduction oriented, its contribution to the consecutive the best UN e-Government rank is limited, and its user-friendly responding system is still lacking. Related research outcomes are rather microscopic focusing only on the models and maturity than implicating on the public policy in a macroscopic manner. In this respect, this study will provide the implication on how EA policy should be. Requirements derived from EA stakeholders and the tasks will be arranged in accordance with its domain, then the performance and tasks will be demonstrated. As guiding EA stake holders and information related officers to setup the EA policy with these results, this study is expected to support information the policy drivers.

Introduction: Mandibular third molar extraction is one of the most common procedures performed in oral and maxillofacial surgery units. Although the overall complication rate is low with most complications being minor, mandibular third molar removal is so common that the population morbidity of complications might be significant. Therefore, efforts to limit intraoperative or postoperative complications might have a significant impact in terms of enhancing the patient outcome. The aims of this study were to identify the position and angulation associated complications after mandibular third molar extractions. Materials and Methods: This study surveyed 568 patients who had a mandibular third molar extracted, showed clinical complications and underwent a radiographic measurement of the available space, depth and spatial relationship. Results: The results obtained were as follows: 1. The complications were a dry socket, nerve injury, root rest, infection, bleeding, hamatoma, and adjacent teeth injury. 2. There were no significant differences between the complication and ramus relationship (available space) of the mandibular third molar. 3. There were no significant differences between the complications and depth of the mandibular third molar. 4. There were no significant differences between the complications and spatial relationship of the mandibular third molar. Conclusion: There were no significant differences in the complication rate, ramus relationship, depth and spatial relationship of the mandibular third molar. This suggests that the position and angulation of the mandibular third molar may not have an impact on the complications. The relationship between the position and angulation of the mandibular third molar, and complications deserves a further study using longitudinal data.

This study has the object of deriving schemes for not only securing safety of chestnuts, which is the most important forest product in terms of both production and exportation, to consumers with implementing persistent production of them in harmony with the environment, but also producing environmentally friendly chestnuts that can contribute to the increase of a farm household's income through price differentiation from other chestnuts, which are grown by generally accepted ways. In order to do this, I performed an analysis of the reality and outcome from the management of farm households that produce environmentally friendly chestnuts. The result of the analysis demonstrated some problems such as poor establishment of farming skills in a beginning stage, administrative problems with weeding operations and prevention of blight, difficulty in ensuring distribution channels and high production cost. Therefore, propelling productive expansion of environmentally friendly chestnuts after resolving these problems requires many supports and ideas: establishment and diffusion of farming skill system under the cooperation of civil and government organizations, construction of environmentally friendly INM (Integrated Nutrient Management) and IPM (Integrated Pest Management), creation of production areas for improving productivity, introduction of 'Institution of Income Conservation for Environmentally-Friendly Production' that can help farmers to preserve integrity of income on their switchover to production of environmentally friendly chestnuts from generally-grown chestnuts, and finally strong and persistent promotion of environmentally friendly chestnuts towards existing farmers and consumers.

Antimicrobial resistance has been a well-recognized problem ever since the introduction of penicillin into clinical use. History of antimicrobial development can be categorized based on the major antibiotics that had been developed against emerging resistant $pathogens^1$. In the first period from 1940 to 1960, penicillin was a dominating antibiotic called as a "magic bullet", although S.aureus armed with penicillinase led antimicrobial era to the second period in 1960s and 1970s. The second stage was characterized by broad-spectrum penicillins and early generation cephalosporins. During this period, nosocomial infections due to gram-negative bacilli became more prevalent, while those caused by S.aureus declined. A variety of new antimicrobial agents with distinct mechanism of action including new generation cephalosporins, monobactams, carbapenems, ${\beta}$-lactamase inhibitors, and quinolones characterized the third period from 1980s to 1990s. However, extensive use of wide variety of antibiotics in the community and hospitals has fueled the crisis in emerging antimicrobial resistance. Newly appeared drug-resistant Streptococcus pneumoniae (DRSP), vancomycin-resistant enterococci (VRE), extended-spectrum ${\beta}$-lactamase-producing Klebsiella, and VRSA have posed a serious threat in many parts of the world. Given the recent epidemiology of antimicrobial resistance and its clinical impact, there is no greater challenge related to emerging infections than the emergence of antibiotic resistance. Problems of antimicrobial resistance can be amplified by the fact that resistant clones or genes can spread within or between the species as well as to geographically distant areas which leads to a global concern$^2$. Antimicrobial resistance is primarily generated and promoted by increased use of antimicrobial agents. Unfortunately, as many as 50 % of prescriptions for antibiotics are reported to be inappropriate$^3$. Injudicious use of antibiotics even for viral upper respiratory infections is a universal phenomenon in every part of the world. The use of large quantities of antibiotics in the animal health industry and farming is another major factor contributing to selection of antibiotic resistance. In addition to these background factors, the tremendous increase in the immunocompromised hosts, popular use of invasive medical interventions, and increase in travel and mixing of human populations are contributing to the resurgence and spread of antimicrobial resistance$^4$. Antimicrobial resistance has critical impact on modem medicine both in clinical and economic aspect. Patients with previously treatable infections may have fatal outcome due to therapeutic failure that is unusual event no more. The potential economic impact of antimicrobial resistance is actually uncountable. With the increase in the problems of resistant organisms in the 21st century, however, additional health care costs for this problem must be enormously increasing.

Block chain technology revolutionizes the 'double entry bookkeeping' of accounting principles in 600 years. It will be an opportunity for you to become one. The advent of the block chain will revolutionize the accounting world. It is no exaggeration to say that it is a skill. The use of block chains for accounting leads to the occurrence of transactions. It's easy to identify a transaction, and it's easy to fake or tamper with it. The accounting industry because it is difficult to communicate transparent accounting information to stake holders. Transformations will be possible across the board (Carlozo, 2017). An entity shall provide financial information that is useful to interested parties in making reasonable economic decisions. Transactions arising from business activities are recorded and provided in the books. Interested parties are here. We need to make decisions to protect our interests and make those decisions rationally. To make a decision, we know how the outcome of the decision will affect our self-interest. Because it has to do so, it uses corporate information for this purpose. But the investor is one way of doing business. It is difficult to trust the information provided by (Yermack, 2017). As a result, ICO companies, startups, small businesses lose a lot of business opportunities because they don't have investors. In addition, the management mixes cash flows with accounting interests to indicate changes in cash flows. It experiences failure in its business due to its inability to analyze and predict faithfully. But it's a blockhead in accounting. Applying the factors and recording them in the book will result in a number of benefits for different stake holders. It can be provided. The financial information in the block chain is not subject to further review or verification. It can improve the timeliness and increase reliability of financial information because it cannot be forged or tampered with (Delloitte, 2016). Based on the fourth industrial revolution, the pace of change in all sectors of society has never been faster. Based on block chain technology, decision-making structure is based on vertical structure of the past. Transforming into a horizontal structure collapses existing tools and advances transparency and decentralization a change of Copernican interpersonal awareness with the trend of the times, which is becoming angry with modern people.
