The purposes of this study are to investigate Korean science teachers' perception of the current science teacher preparation courses in Korea, especially focused on subjects of science education, and to induce implications for improvement of in-service program for science teachers. To do this, a questionnaire was developed by the authors and administered to the 215 science teachers sampled nationwide. The study concluded that science teachers perceived that the two compulsory subjects, 'science education theories' and 'science teaching-learning materials and teaching methods' were not enough for a professional science teacher. Particularly, they consisently insisted that more practices under the relationship with teaching science in schools were necessary when learning subjects of science education. Based on science teachers' response, we recommended that the following 4 subjects should be added in the course of pre-service program for science teachers: 'Development of experiment/demonstration devices', 'Teaching creativity and education for the gifted in science', 'Development of science teaching materials', and 'Science inquiry learning and teaching'.

Parial drainage characteristics of clayey silt with low plasticity from the west coast (Incheon and Hwaseong) was analyzed using CPTU based existing correlation equations and compulsory replacement method. Generally, the estimated $OCRs={\kappa}{\cdot}((q_t-{\sigma}_{vo})/{\sigma}^{\prime}_{vo})$ using Powell and Quartman(1988) were higher than those obtained by the oeodometer tests. These trends were noticeable for the layers containing a lot of silty and sand soils. The assessment of partial drainage conditions was performed through Schnaid et al. (2004)'s equation; it is based on plotting the normalized cone resistance, $Q_t$ versus the pore pressure parameter, $B_q$ in combination with the strength incremental ratio, $s_u/{\sigma}^{\prime}_{vo}$ to the CPTU data. It is evident that more than half of the data fall in the range where $B_q$ < 0.3, corresponding to the domain in which the partial drainage prevails when testing normally consolidated soils at a standard rate of penetration (2 cm/s). To estimate the replacement depth of clayey silt with low plasticity, back analysis was carried out to evaluate the internal friction angle based on where the design depths are equal to the checked depths using bearing capacity equation. The internal friction angels obtained from the back analysis tended to increase as the plasticity index decreases, which is ranged approximately from ${\varphi}^{\prime}=2^{\circ}$ to ${\varphi}^{\prime}=7^{\circ}$.

In January and August 2019, there were amendments to the Unfair Competition and Trade Secrets Protection Act (UCPA) and the Industrial Technology Protection Act(ITPA). These amendments will contribute to technology protection. But these amendments need to be supplemented further. In the area of civil remedies, despite the introduction of treble damages in the case of the UCPA and ITPA, the provisions related to the submission of supporting data have not been maintained. Therefore, it is necessary to recognize the claim of the other party as true if it is maintained at the level of the revised Patent Act and the scope of submission of supporting data. And the enforcement of the case of compulsory submission for the calculation of damages, and the order of filing documents are not followed. ITPA, on the other hand, has introduced the compensation for damages, but there is no provision for estimating the amount of damages. Therefore, it is necessary to estimate the amount of lost profits, profits, and royalties. In the area of criminal remedies, both the UCPA and ITPA have raised the penalty, but the sentencing regulations are not maintained. In addition, although the recent outflow of technology has expanded beyond organizational deviations to organizational outflows, amendments need to be made in relation to the serious consequence for the punishment of related juristic persons, such as companies involved in it. It should be noted that Japan and the United States have corporate regulations and regulations. In addition, in relation to the confiscation system, Act on Regulation and Punishment of criminal proceeds concealment require that domestic defenses be confiscated by defense industry technology, while trade secrets and industrial technologies are confiscated only by "foreign" outflows, and an amendment is necessary.

This study discussed the validity and necessity of compulsory recording of radiographic examination performed by radiological technologist on patients in medical institutions related to radiation exposure. Also, this study provided reasonable evidence of radiographic examination related medical records can contribute to the improvement of public health. Based on overseas cases of implementing a radiographic examination record system, the essential items to be included in medical record are the exposure date, exposure time, exposure method, exposure conditions that is tube voltage, tube current. Name and license number of the radiological technologist who performed the examination should be include in medical record. It is expected that the medical record of the total amount of radiation exposure per year would be in giving the maximum benefit with the minimum exposure to the medical radiation examination of the patient. In addition, interventional radiography medical record should also include exposure time, type and dose of the contrast medium.

In order for learners with different characteristics to reach meaningful learning, the curriculum - class-assessment must be integrated. In this study, we classified the integration into three aspects: content compatibility, operator convergence, and institutional connectivity, and looked at the status of unifying special classes in general schools from each perspective. As a result of the study, in terms of content suitability, adjustment of the curriculum to those subject to special education-professorial revision-assessment adjustment was not performed well except for subjects where individualization professors were conducted. From an actor's perspective, the ambiguity of the roles of general and special teachers resulted in the inability of curriculum coordinators, educators, evaluators and others to agree or even minimal consultations. In terms of institutional linkage, the authority and role of curriculum coordination, professorial revision, and assessment coordination were unclear except for subjects where individualization professors were conducted. As an alternative to discuss and remedy these problems, it proposed increasing awareness of individualized education, compulsory consultation and institutional readjustment.

Genetically modified (GM) crops have been developed worldwide through the recombinant DNA technology and commercialized by global agricultural companies. Until now, GM crops have not been cultivated commercially in Korea. Commercialization of GM crops requires a compulsory assessment of environmental risk associated with the release of GM crops. This study was conducted to evaluate the frequency of pollen mediated gene flow from Bt transgenic rice (Agb0101) to japonica non-GM rice (Nakdongbyeo), indica non-GM rice (IR36), and weedy rice (R55). A total of 729,917, 596,318 and 230,635 seeds were collected from Nakdongbyeo, IR36, and R55, respectively, which were planted around Agb0101. Selection of the hybrids was determined by repeated spraying of herbicide and Cry1Ac1 immunostrip assay. Finally, the hybrids were confirmed by PCR analysis using specific primer. The hybrids were found in all non-GM rice and out-crossing ranged from 0.0005% at IR36 to 0.0027% at Nakdongbyeo. All of hybrids were located within 1.2 m distance from the Agb0101 rice plot. The meteorological elements including rainfall and temperature during rice flowering time were found to be important factors to determine rice out-crossing rate. Consideration should be taken for many factors like the meteorological elements of field and physiological condition of crop to set up the safety management guideline to prevention of GM crops gene flow.

This study has examined how the welfare system has changed as it has passed through the most controversial period in Korean modern history. The welfare system has changed in a way that adapts to the need for export-led economic growth. Industrialization centered on light industry, which started in the mid-1960s, absorbed the labor force that existed in the rural areas and commodified them, thereby creating a momentum for Korean society to get out of poverty. However, the public de-commodification, ie social security system, adapted to the commodification of the labor force has been institutionalized only in a very limited area and people. Indeed, the de-commodification system was confined to the area directly linked to the reproduction of the labor force. Even so, the target was very limited in the abundance of labor in rural areas. Compulsory medical insurance was rejected because of corporate burden, and industrial accidents insurance was introduced centering on large-scale workplaces. As the Korean economy began to move from the light industry to the heavy industry in the 1970s, the commodificated labor force changed from a low skilled labor force to a skilled male labor force. It is at this time that dual structures have begun to be created between workers employed in export-oriented large enterprises and workers employed in domestic-oriented SMEs. Therefore, the system of de-commodification that supports the reproduction of labor power in response to social risks has also been institutionalized centering on large-scale workplaces.

This paper aims to analyze the Award wage system in Australia for construction workers. Considering low wages and precarious employment situation of construction workers in general, it is of advantage especially for them in Australia. Furthermore, it seems to be instructive for Korean construction workers, who stand in more precarious and unstable situation and furthermore are lack of fair wage and social safety. After strong and longstanding labour struggle in the late 19th century in Australia, it has been established a tripartite institution called as 'tribunal' between trade unions, employers, and the government. Under the highly institutionalized form of industrial relations, it functions as an arbitration and conciliation system between labour and management. The Award wage system stands in the middle point. This Award wage system including various welfare provisions is settled by the tribunal, today renamed as Fair Work Commission. In this wage system should be defined level of minimum wages according to the various skill levels, which are in turn connected with compulsory superannuation and Medicare as well as vocational education and training. Furthermore, it provides especially for the construction workers, who suffer from job instability, so-called 'portable benefits', which relate to long service leave and redundancy pay. Considering general conditions of precarious construction workers in Korea, In that respect, the Australian Award wage system would be very instructive for our social wage and safety system for construction workers.

Coastal cities suffer a great deal of storm and wind damage. The storm and wind characteristics vary between cities. Therefore, a storm and wind damage management system suited for specific characteristics is required for each coastal city. In this study, we analyze the current situation and establish the problem of storm and wind damage management system in regards to urban management, coastal management and disaster management. We also review the storm and wind damage management system for the USA and Japan. We consequently propose a plan to improve the storm and wind damage management system. As a result of the study, in terms of city management, we recommend the compulsory identification of disaster prevention districts, implementation of the integrated coastal city management plan, designation of natural disaster risk mitigation area as disaster prevention district, the division of disaster prevention district into wind damage prevention district, storm damage prevention district, erosion damage prevention district, the building of restrictions at the disaster prevention district by ordinance, etc. In regards to coastal management, we suggest the delegation of authority to delegate coastal erosion management area to the local government, the subdivision of coastal erosion management area into erosion serious area, erosion progress area, erosion concern area, the building restrictions at coastal erosion management area by ordinance, development of erosion prediction chart, etc. In relation to disaster management, we recommend the integration of "countermeasures against natural disasters act" and "disasters and safety management basic act", the local government-led disaster prevention system, the local disaster management network, and the customized local disaster prevention plan, etc.

Green spaces are recognised for the benefits. They bring to the quality of people's lives. However, since the 1980s there has been a general increase in poorly-managed green spaces. In an attempt to address this issue, green space policy has changed its focus on green space management through the gradual introduction of green space evaluation tools, such as the Green Flag Award (GFA). The GFA, as an established green space evaluation tool in the UK, reflects a shift in policy drivers of green spaces management. However, there is a lack of research investigating the contextualisation between a wide range of policy contexts and such green space evaluation tools (the GFA in this study). The aims of this study are therefore to explore the development of green space evaluation since the late 1990s, with respect to the growth of the GFA and its impact on other evaluation tools across the UK and several countries. To address the aims, this study employs in-depth literature reviews on UK green space policy mainly conducted by government. In addition, case studies are presented, focusing on the GFA and independent green space evaluation tools intrinsically derived from the GFA in the UK's cities and Nordic countries. Results show that based on the awareness of the severity of declining standards of green spaces, newly emerging policy arrangements have been adopted to address negative issues, which affect the standard of green spaces such as the transfer of responsibility for green space management, the implementation of Compulsory Competitive Tendering and ongoing budget cuts. Significantly, the GFA's indicators reflect the emerging changes of economic and social contexts associated with green spaces management where, in particular, the prospect of continuous budget cuts, which encourages communities to become involved in green space management. The GFA has widely contributed to leading such UK's cities and other countries to be able to create their independent green space evaluation tools in different approaches based on stakeholders' (mainly community) involvement in the decision-making process of green space evaluation. In conclusion, this study implies that successful green space evaluation tools do embody the value of green spaces and address drivers of emerging green space management with correspondence to the context of policy arrangements. Importantly, stakeholders have an opportunity to be involved in a partnership in the decision-making process through some green space evaluation tools. It is hoped that for well-managed green spaces this study will contribute valuable knowledge to our existing understanding of green space management in an era of austerity.
