Construction Standard Unit Price is the unit price calculated based on the market price for work items in construction projects that have already been conducted. It is used as basic data for calculating the budget price of public construction projects. In the Construction Standard Unit Price Book implemented in the second half of 2020, there are 1,810 types of unit prices. Since 2017, 100-150 construction standard unit prices have been revised semiannually (on January 1 and July 1 of each year) through Construction Site Surveys. Other work items have been set based on the rate of inflation during the corresponding period. Later in 2020, this procedure was changed, with on-site survey period extended to one year to strengthen the construction standard unit price investigation. The revisions previous announced during the second half of the year were changed only to reflect the price inflation rates. With such changes in the revisions to construction standard unit prices, one important issue that was raised: The timing of announcing the revisions during the second half of the year (reflecting the price inflation rates). The market unit wage, which is the unit price standard of labor cost that takes up a large part of the construction cost, is announced in January and September. The figures announced in September is reflected on the construction standard unit price four months later in January, but the market unit wage announced in January is reflected only six months after in July, which causes a timing issue. As such, the current study analyzed problems rising from the changed timing of the announcements of the construction standard unit price during the second half of the year, in addition to analyzing their impact on public construction projects.

Korea is recognized as the most advanced nation in regards to capabilities or environments of informatization throughout the world. Nevertheless, Korea brings on itself such stigmas as a nation vulnerable to information security. Now the globe ushered in an era requiring political balances. Yet, issues of legislative supports or system adjustments for information security policies are always pushed back on the priority list. There is a need to face problems at the center of changes departing from such frames. In order to establish a proper system for information security policies, the most urgent issues are reviews of concepts and reorganizations of systems, and then to legislate information security polities by being harmonious with public opinions. This paper is to remind what measures are needed to improve the system of priority policies depending on public backgrounds and why such measures are needed. Furthermore, the paper suggests a new legislation, 'Information Security Policy Act' as one of the specific measures.

우리나라가 급속한 성장을 이루는 과정에서 원자력은 이를 뒷받침하며 함께 성장해 왔다. 그러나 그 과정에서 안전보다 성과를 강조하다보니 안전을 경시하는 비정상적 환경이 조성되었다. 그 결과 숨겨져 있던 과거의 원전 비리가 수면 위에 드러났고, 같은 시기에 후쿠시마 사고로 인한 오염수 유출과 전력난까지 발생하면서 국민의 불안과 불신을 가중시켰다. 국민들은 정부가 불안감을 해소해 주고 원칙을 지키는 안전규제, 신뢰할 수 있는 안전규제를 마련할 것을 요구하고 있다. 원자력 안전규제의 독립성을 확보하기 위해 지난 2011년 설립된 원자력안전위원회는 출범 이후 새로운 안전규제 제도 시스템을 마련하는 데 총력을 기울여 왔다. 원전 비리 같은 비정상 관행을 근절하기 위해 공급자 검사 제도, 성능검증기관 관리 제도 등 새로운 규제 시스템이 마련되었고, 방사선 작업 종사자 보호 강화와 생활 주변 방사선 감시 효율성 제고를 위한 다양한 제도적 장치들도 구비되었다. 이외에도 원자력안전규제기금 설치, 원전 부지별로 설치된 원자력안전협의회 실효성 제고 등 소통과 협업을 위한 시스템을 정착시켰다. 그러나 단순히 제도와 시스템이 만들어졌다고 해서 원자력 안전이 저절로 확보되는 것은 아니다. 차고 다닐 옥의 종류가 바뀌면 걸음걸이도 바꾸어야 한다는 개옥개행(改玉改行)의 고사성어에서처럼 제도가 바뀌면 그에 따른 일하는 방식 문화가 달라져야만 변경된 제도 시스템이 완전히 정착될 수 있을 것이다. 이를 위해서는 규제기관의 노력도 중요하지만 무엇보다 필요한 것은 원전 및 방사선 관련 사업자, 이해 관계자 나아가 일반 국민들이 이러한 달라진 제도 시스템을 이해하고 이에 적극 협조해 나가는 것이다. 본 기획 기사는 그러한 취지에서 그간 원자력안전위원회가 안전규제를 공고히 하기 위해 추진해 왔던 주요 규제 정책, 제도들을 소개하는 데 주안점을 두었으며, 이를 통해 원전 및 방사선 관련 사업자와 일반 국민들의 이해를 바탕으로 새로운 제도 시스템이 조기에 성공적으로 정착될 수 있기를 희망한다.

Purpose: In cases of locally advanced non-small cell lung cancer (NSCLC), concurrent chemoradiotherapy(CCRT) is the leading therapeutic modality. However, much controversy exists about the chemotherapeutic regimens and radiation methods. Materials and Methods: During concurrent chemoradiotherapy, three or four cycles of gemcitabine ($500\;mg/m^2$) and cisplatin ($30\;mg/m^2$) were administered every two weeks while 50.4 Gy of irradiation was administered in 28 fractions (once/day, 5 treatment days/week) to the tumor site, mediastinum, and the involved lymph node region. In addition, a booster irradiation dose of 18 Gy in 10 fractions was administered to the primary tumor site unless the disease progressed. Two or three cycles of consolidation chemotherapy were performed with gemcitabine ($1,200\;mg/m^2$, $1^{st}$ and 8th day) and cisplatin ($60\;mg/m^2$) every three weeks. Results: A total of 29 patients were evaluable for modality response. Response and treatment toxicities were assessed after concurrent chemoradiotherapy and consolidation chemotherapy, respectively. One patient (4%) achieved a complete response; whereas 20 patients (69%) achieved a partial response after concurrent chemoradiotherapy. Following the consolidation chemotherapy, three patients (10.3%) achieved complete responses and 21 patients (72.4%) achieved partial responses. The median follow-up period was 20 months (range $3{\sim}39$ months) and the median survival time was 16 months (95% CI; $2.4{\sim}39.2$ months). The survival rates in one, two, and three years after the completion of treatment were 62.7%, 43.9%, and 20%, respectively. Complications associated to this treatment modality included grade 3 or 4 esophagitis, which occurred in 15 patients (51.7%). In addition, an incidence of 24% for grade 3 and 14% for grade 4 neutropenia. Lastly, grade 2 radiation pneumonitis occurred in 6 patients (22%). Conclusion: The response rate and survival time of concurrent chemoradiotherapy with biweekly gemcitabine ($500\;mg/m^2$) and cisplatin ($30\;mg/m^2$) were encouraging in patients with locally advanced NSCLC. However, treatment related toxicities were significant, indicating that further modification of therapy seems to be warranted.

This study examines trends by school level, region, subject, and type centered on elementary schools when private education is perceived as a social problem due to the overheating of private education and its over-dependence. This study aims to provide a direction to ease the school mathematics education and meet the expectations of school mathematics education. As a result of this study, in mathematics subjects, the graph of private education expenses for mathematics subjects was not affected by the period and showed a somewhat consistent linear trend. In other words, we found that the private education cost of the mathematics subject was solid compared to other factors, and was not significantly affected by external variables, and was consistent. It is meaningful to examine the trends of private education costs in mathematics subjects with a comparison between the past and present and to grasp what factors and how they have changed and developed.

This study is subjected to those gardens of the Korean Folk Village 'Oeam-Ri' designed in 1920s. - transitional period of traditional gardens - and define socio-cultural change's influences and through documents on garden design, descendant's testimony and measured drawings, to understand that period's garden culture's characteristics according to garden design elements. This study applied following analysis methods and procedures to derive out characteristics of transitional garden culture. Analysis on socio-cultural characteristics in 1920s. Analysis on actual condition of transitional garden's design. In this point Outline of the Garden, Space formation, Garden designing elements are (1) water landscape, (2) plant, (3) structures, (4) paving, to derive out characteristics of the transitional garden. The results follow as below; First, during the transitional period 1920s, the economical development, fueled by opening nation's door to foreign countries and indication of collapse of statue systems together with idea of practical science and Enlightenment Thought, was element of changes in garden style. Second, Garden Designers of transitional gardens in 'Oeam-Ri' were limited to upper class of the society. They were wealthy enough to maintain their high social statue in rapidly changing society. As results, tendency of returning to nature developed gardens located in a site of scenic beauty and development of geographical features arranging techniques, and also showed copying foreign styles. Third, arrangement of garden and space composition, in most cases, composed of buildings and yards. Changes in water landscape features and garden spaces are centered to main-yard. Major changes of the garden spaces are water landscapes and plants that showing foreign influences. Fifth, scenic appearance techniques appears with dense garden space and emphasizing visual scenic view. Sixth, the characteristics of transitional garden design techniques are development of geographical feature arranging techniques, changes and mixture of the materials and garden types, emphasizing garden's decorative beauty, change of concept of yard within house into garden, changes from 'borrowing of landscapes' to 'selecting landscapes', changes of front garden from emptiness to fullness, changes of attitudes of enjoying gardens from 'staying calm in the garden' to 'moving or walking in the garden', changes to inner-oriented view, and changes from 'just watching and enjoying the nature' to 'enjoying specific objects'. This study is one of the efforts to restore the identity of Korean Traditional Garden by approaching and observing modern era which function as bridge between tradition and present day, and we observed transitional aspects of changes of traditional garden into modern garden. Hereafter, more studies will be needed to Modern Garden Design be recognized as part of Korean Garden Design History and these would be author's next assignment.

The current study described the history of Islamic extremism and the recent expansion of international Islamic extremism in Indonesia. For doing so, both content analysis of the existing written documents and qualitative interviews were conducted. For the content analysis, media reports and research articles were collected and utilized. For qualitative interviews, Indonesian students and workers in Korea, Korean spouses married to Indonesian, and Korean missionaries in Indonesia were contacted and interviewed. Qualitative interview was conducted between 30 minutes and 2 hours. On the spot, interviews were recorded and later transcribed into written documents. Due to the difficulty of identification of population and the uneasiness of accessability to th study subjects, convenient sampling and snowball sampling were used. According to the results, Islamic extremism in Indonesia had a deep historical root and generally shared similar historical experience with other muslim countries such as Afghanistan, Pakistan, Egypt, and Saudi Arabia where Islamic extremism was deeply rooted in. That is, Islamic extremism began as a reaction to the western imperialism, after independence, Islamic extremism elements were marginalized in the process of construction of the modern nation-state, and Islamic extremist movement was radicalized and became violent during the Soviet-Afghan War. In addition, after 9.11, Islamic extremism in Indonesia was connected to international Islamic extremism network and integrated into such global movement. Such a historical development of Indonesian Islamic extremism was quite organized and robust. Meanwhile, the eastward infiltration and expansion of international Islamic extremism such as IS and Al Qaeda was observed in Indonesia. Particularly, such a worrisome expansion was more clearly visible in the marginalized and underdeveloped countrysides in Indonesia. Such expansion in Indonesia could negatively affect on the security of South Korea. Geographically, Indonesia is proximate to South Korea. This geographical proximity could be a direct security threat to the Korean society, as if Islamic extremism in North Africa and Middle East becomes a direct security threat to Europe. Considering the presence of a large size of Indonesian immigrant workers and communities in South Korea, such a concern is very realistic. The arrest of an Indonesian Islamic extremism supporter in November, 2016, could be a harbinger of the coming trend of Islamic extremism expansion inside South Korea. The Indonesian Islamic community in South Korea could be a passage of Indonesian Islamic extremism into the South Korean society. In this context, it is timely and necessary to pay an attention to the recent trend of Islamic extremism expansion in Indonesia.

This study investigated the process of change of 32 urban parks designated during the period of Japanese colonial rule according to growth and development of the city in Busan. Particularly, researching included analyizing books, notification, data, and documents relevant to the history of urban planning published by Busan city. As a result, Daejeong Park, Gokwan Park, and Yongdusan Park had been utilized by Japanese residents under the Japanese colonial rule before planning of urban parks, and 32 parks legally specified in 1944 were planned by considering the prevention against disasters. After emancipation, there were an unauthorized building, housing construction, business district, public office, and school facility in the sites of the parks due to the influence of the Korean War and reorganization of urban planning. The majority of parkways and small parks downtown were eliminated. However, unexecuted parks that the government had designed on the edge of town during the Japanese colonial period have become major parks downtown through the city's growth. Yeonji Park, Yangjeong Park, and Danggok Park have been being building as a business of parks for a comfortable city, forming downtown along with the Green-Busan Policy. Thus, 32 parks designated under the Japanese colonial rule have made or got out of use reflecting on the phases of the times of modern Korean society. It turns out that these parks need an investigation about condition for land possession and purchase of the site of the parks in order for social common capital.
