Teh $polA^{+}$ gene can be transducted in a multicopy mini-Mu plasmid, but not cloned because the product of this gene is lethal when overproduced. Although, we obtained one surviving cell, in which the ColEl-derived mini-Mu plasmid suffered a spontaneous deletion exactly at the region where the $polA^{+}$ gene was cloned. The $PolA^{+}$ unstream flanking sequence containing the promoter and pribnow-box was delected in vivo ; consequently this gene is not able to be expressed.

Recently, it is becoming increasingly difficult to ignore carbon emission implication of building operations due to the significant rate of energy usage in buildings. In the building sector, our normal expectation implies that large building floor area induces more greenhouse gas (GHG) emission. In this research, the correlation between building total floor areas and GHG emission was explored by simple linear regression and analyzing the yielded residuals for confirming this seemingly obvious conjecture. By looking at the generated regression lines drawn based on the data sets representing public facilities in Ontario, Canada, we were able to confirm that carbon emission rate shows a proportional increase or decrease depending on the total floor area of buildings as has been implied as a conjecture. Some buildings were found to emit significantly large and small amount of GHG, and we addressed potential reasons why those buildings show the deviation from the confirmed proportional interrelation between a building's total floor area and the amount of GHG emission.

The followings are required to establish uniform principle of criminal jurisdiction for international cyber crime into customary international law; (1) clear guideline of UN for promoting national practice (2) formation of general practices based on these guidelines (3) these general practices should obtain legal confidence. International society is in close cooperation for investigating and controlling cyber threat. The US FBI has closed down the largest online crime space called 'Darkcode' and prosecuted related hackers based on joint investigation with 19 countries including England, Australia, Canada, Bosnia, Croatia, Israel, and Rumania. More and more people in Korea are raising their voices for joining cyber crime treaty, 'Budapest Treaty.' Budapest Treaty is the first international treaty prosecuting cyber crime by setting out detailed regulations on internet criminal act. Member countries have installed hotline for cyber crime and they act together. Except European countries, America, Canada, and Japan have joined the treaty. In case of Korea, from few years before, it is reviewing joining with Ministry of Foreign affairs, Ministry of Justice and the National Police but haven't made any conclusion. Different from offline crime, cyber crime is planned in advance and happens regardless of border. Therefore, international cooperation based on position of punishing criminals and international standards. Joining of Budapest international cyber crime treaty shall be done as soon as possible for enhancing national competence.

This study examines the characteristics of teacher education system and professional standards of teachers in Canada through analysis of the current teacher education curriculum and salary grids of teachers in Canada. As a result, the following characteristics were found. First, contents and theories acquired during the course of teacher education are connected to the actual practice to increase the site-compatibility. Second, professional standards of teachers is rather holistic, than detailed and systematic. Based on the findings, the following implication can be drawn. To enhance the site compatibility of teachers in the Republic of Korea, it is requisite to build a persistent, and cooperative relationship among the faculty members of teacher education program, the members of the community, and supervisor teachers of practicum schools. Also, it is necessary to come up with a system that directly connects the professionalism of the teachers and the salary grids, as the salary of teachers are adjusted according to the completion of degree or courses, reflecting the professionalism.

Background: At the end of the'Waste Drug Disposal Project', collection and disposal of waste drugs remain a social issue. Objective: This study aimed to provide suggestions to improve the drug waste management system in Korea by comparing domestic and overseas relevant programs. Methods: This is a comparative study between South Korea, Australia, Canada, France, and the US. These overseas countries were selected because they have been operating waste drug management programs continuously to date. Comparison was conducted by a pre-determined analysis frame including legal regulation, enforcement program and its performance. Results: All selected countries except Australia had legal regulations on drug wastes. The US had the largest variety of drug waste disposal methods. Canada had recommended that pharmacies actively participate in drug waste withdrawal programs. France had the largest variety of methods to promote relevant programs, including window sticker, SNS, and app, as well as the highest level of awareness and participation. Australia had the lowest level of awareness and participation in pharmaceutical waste management programs. Pharmaceutical companies took responsibility of paying for these programs in the selected overseas countries. Conclusion: Further efforts should be made to establish a clear guideline including the role of pharmaceutical companies, and to develop various methods for the public to be aware of appropriate ways of disposing drug wastes in Korea.

This paper focuses on finding the way of aerospace industry promotion in Korea compatible with fair trade system under international rules by considering and analysing the WTO subsidy rules and WTO dispute settlement cases. As for subsidy rules in WTO, the paper deals with two matters such as financial contribution and benefit and further studies provisions on the prohibited subsidies and actionable subsidies. And as for the dispute settlement matters, it reviews the Brazil-Canada case and the US-EC case on civil aircraft export subsidies. While aerospace industry in Korea is not yet internationally competitive still requiring government's continuous supports, it must not be in conflict with subsidy rules under WTO mechanism. This paper makes several suggestions to meet these conditions.

This study analyzed policies and guides related to the acquisition of private records at state/provincial archives in the U.S., Canada, and Australia. The purpose of this study is to examine the current status of collecting private records in the governmental archives. The analysis was made based on policies and guides from 14 state/provincial archives, including five in the US, seven in Canada, and two in Australia. From the analysis, the study examined collection areas, types of private records, and colleting methods, such as donation or deposit. It also studied the considerations on transferring copyright, placing access restrictions, and disposing of records. The study made the following suggestions for collecting private records at public archives in Korea: (1) define the collecting areas of private records relevant to the characteristics of a region; (2) determine the acquisition methods, including donation or deposit, and establish a procedure to make an agreement for the transfer of ownership, including copyright, access restriction, and disposal of records; (3) develop cooperation among the related institutions within a region.

Published data of the efficiency of CR-39 detectors as a function of neutron energy from different laboratories show wide variations in the response obtained. These variations result from differences in etching conditions, in the materials and thickness of the radiator, in the sensitivities of CR-39 from different manufacturers and perhaps in criteria used for the size of spots that are counted. This paper describes some effects of these factors on the energy and angular response with calculational results. Calculated and measured results of the variations of response with neutron incident angie are more consistent than those of energy response. The data calculated show that the angular response is not a strong function of neutron energy except below about 0.3 MeV.
