Text-mining technique in the past had difficulty in realizing the analysis algorithm due to text complexity and degree of freedom that variables in the text have. Although the algorithm demanded lots of effort to get meaningful result, mechanical text analysis took more time than human text analysis. However, along with the development of hardware and analysis algorithm, big data technology has appeared. Thanks to big data technology, all the previously mentioned problems have been solved while analysis through text-mining is recognized to be valuable as well. However, applying text-mining to Korean text is still at the initial stage due to the linguistic domain characteristics that the Korean language has. If not only the data searching but also the analysis through text-mining is possible, saving the cost of human and material resources required for text analysis will lead efficient resource utilization in numerous public work fields. Thus, in this paper, we compare and evaluate the public document classification by handwork to public document classification where word frequency(TF-IDF) in a text-mining-based text and Cosine similarity between each document have been utilized in big data environment.

지구온난화와 기후변화의 영향으로 전 지구적으로 이상홍수, 이상가뭄, 한파와 같은 이상기상 현상이 빈번하게 발생하고 있다. 국내에서는 2010년 추석 광화문 침수사태와 2011년 우면산 산사태와 같은 국지성 집중호우로 인한 인적 물적 피해가 속출하고 있다. 전통적으로 시기나 양적인 측면에서 대부분 장마기간에 국한되었던 강우집중현상이 과거와 달리 특정기간에 상관없이 발생하고 단기성, 국지성을 지닌 호우의 발생빈도가 높아지는 등 국내 강우의 특성이 변하고 있다. 이러한 변화에 대응하기 위해서 강우예측과 유출량예측의 정확도를 높이기 위한 시도가 다양하게 이루어지고 있다. 강우예측의 정확성을 높이기 위해 기상청에서는 단기예보를 목적으로 전지구 통합모델과 지역 통합모델을 연계한 동네예보를 수행하고 있으며, 초단기 예보를 위한 목적으로 VSRF, SCAN, VDRAS, MAPLE 등의 예보를 수행하고 있다. 홍수량 예측에서는 일반적으로 사용하고 있는 물리적 기반의 모형에 레이더강우와 같은 격자형 강우자료를 사용하여 정확성을 높이거나, 기존의 집중형 모형을 분포형 모형으로 대체하기 위한 연구 등이 이루어지고 있으며, 모형 구축이 간편하고 예측 정확도가 우수하다는 장점으로 인해 신경회로망이나 퍼지추론기법 등을 사용한 연구도 지속적으로 이루어지고 있다. 본 연구에서는 수자원분야에 산재한 불확실성을 적극적으로 인정하고 수학적으로 해석하기 위한 이론인 퍼지이론에 신경망 이론을 도입한 neuro-fuzzy 기법을 사용하여 홍수량을 예측하였다. 모형의 입력자료로는 관측된 강우자료와 유출량자료 및 기상청에서 제공하는 MAPLE(McGill Algorithm for Precipitation Nowcasting by Lagrangian Extrapolation) 강우예측자료를 사용하여 적용성을 평가해보았다. 모형의 적용성을 평가하기 위해 시험유역을 충주댐 상류 유역으로 선정하였으며, 2010년 2011년 홍수기의 충주댐 유입량을 예측하였다. 모형의 입력자료를 변경하여 입력자료의 변화에 따른 결과를 비교하였고, clustering 반경의 변화에 따른 정확도를 비교하였다. 모형의 정확도는 평균제곱근오차와 첨두수위오차를 통해 비교하였으며, 비교결과 전반적으로 lead time이 길어질수록 MAPLE 사용 시 예측 정확도가 우수하였고, clustering 반경은 0.5일 때 가장 우수한 결과를 보였다.

생활·공업용수 목적의 하천수 사용량은 유량계 등 검증된 방법으로 사용량 계측 및 실적보고를 수행하고 있으나, 농업용수는 검증되지 않은 수문조작 등의 간접방법을 인정하고 있어 사용실적 자료의 신뢰도가 낮은 실정이다. 하천수의 효율적인 물 배분을 위해 농업용수 사용량 자료에 대한 신뢰도 확보 및 자료관리 기반 마련이 필요하다. 본 연구에서는 전국 수리권일제조사 자료를 이용하여 농업용수 사용시설에 대한 구분 및 정리를 통해 수집체계 구축 대상을 선정하고, 사용시설의 형태 및 규모에 따라 적정 계측기술 적용 방안 및 연차별 구축 계획을 통해 농업용수 사용량 자료를 관리할 수 있는 방안을 제시하였다. 조사된 전체 하천수 사용시설 중 제원정보 및 허가량이 유효한 14,575건 중 농업용수는 12,745건으로 개소수 대비 88.9%, 허가량 대비 81.3%(생활·농업·공업용수 대상)를 차지하고 있다. 이중 하천수 사용량 보고대상인 8,000 m³/일 이상의 1,696건에 대한 자료의 수집이 수행된다면, 전체 농업용수의 86.0%에 해당하는 사용량 자료를 확보할 수 있다. 수집체계 구축 대상 1,696건의 시설형태별(양수장, 취수보), 규모별(허가량 10만 m³/일 기준) 구분을 통해 취수보와 양수장의 최적 계측방법 선정 및 연차별 구축 계획을 수립하였다. 전국에 산재한 전체 농업용수 사용량 자료의 확보가 현실적으로 어렵기 때문에, 적정 개소수의 수집체계 구축 및 운영으로 전체 농업용수 사용량의 상당부분 자료를 확보할 수 있다면 실시간 하천수 관리 및 효율적인 물 배분을 위한 기반을 마련할 수 있을 것이라 기대한다.

Art. 2 Abs. 1 GG sch${\ddot{u}}$tzt umfassend die allgemeine Handlungsfreiheit. Daher bed${\ddot{u}}$rfen private Handlungen grunds${\ddot{a}}$tzlich keiner gesetzlichen Erm${\ddot{a}}$chtigungsgrundlage. Dies gilt selbstverst${\ddot{a}}$ndlich auch fur die Unternehmen der Bewachungsbranche. Allerdings ist es bei der Aus${\ddot{u}}$bung der Bewachungsaufgabe typisch, mit Strafe oder zumindest Schadensersatzpflicht sanktionierte Tatbest${\ddot{a}}$nde zum Nachteil Dritter zu verwirklichen. F${\ddot{u}}$r solche F${\ddot{a}}$lle stehen den Bewachungspersonen m${\ddot{o}}$glicherweise Rechtfertigungsgr${\ddot{u}}$nde zur Seite. Dadurch wird ein ansonsten rechtswidriges Handeln rechtm${\ddot{a}}$${\ss}$ig und so wird im Ergebnis eine Strafbarkeit (wie auch eine Schadensersatzpflicht) ausgeschlossen. Dabei wird klargestellt, dass dem Sicherheitsgewerbe au${\ss}$er in den F${\ddot{a}}$llen der gesetzlichen ${\ddot{U}}$bertragung der hoheitlichen Befugnisse nur die vom Auftraggeber vertraglich ${\ddot{u}}$bertragenen privatrechtlichen Befugnisse sowie die Jedermannsrechte zustehen Au${\ss}$erdem soll im Rahmen der Privatisierung der Gefahrenabwehraufgaben auf solche spezialgesetzlichen Regelungen hingewiesen werden, bei denen Bewachungspersonen mit der hoheitlichen Wahrnehmung bestimmter Sicherheitsaufgaben betraut, d.h. dazu befugt sind, Sicherheitsaufgaben in den Handlungsformen des ${\ddot{O}}$ffentlichen Rechts 면켜${\ddot{u}}$ben. In der koeranischen Literatur ist die Handlungsgrundlage des Bewachungspersonals bis jetzt kaum n${\ddot{a}}$her untersucht. Im allgemeinen werden strafrechtliche Rechtferigungsgr${\ddot{u}}$nde, z.B. Notwehr, Notstand und Selbsthilfe, als dabei anwendbare Normen anerkannt. In dieser Arbeit wird festgestellt, dass die privaten Sicherheitsdienstleister in beiden L${\ddot{a}}$ndern durch die Gewerbegenehmigung au${\ss}$er in den F${\ddot{a}}$llen der Beleihung keine hoheitlichen Befugnisse erhalten. Als Handlungsgrundlage kommen nur die allgemeinen Not- und Jedermannsrechte im Rahmen von Straf-Strafprozess- bzw. Zivilrecht in Betracht.

The early history of foreign Protestant missionaries in Korea has begun in the late 19th century, when they came to work as professionals such as teachers, medical doctors, etc. as the nation opened its door to western culture with the fall of national isolationism. Their records are considered crucial resources that enable us to shed new light on modern Korean history, politics, economy and society beyond mere religious value. Despite the recognition of such historic value of early missionary resources, however, there has been serious lacking of a systematic attempt to develop policies and plans for making it easy to collect, preserve and access the resources. Up to date, the records of early Protestant missionaries, in diverse forms of mission reports, books, periodicals, personal diaries, letters and photos, are scattered around various places, including their home country churches, governments, libraries, museums, research institutes and homes. Therefore, this research aims at providing basic resources on the archival status of early Protestant missionaries in Korea, needed for developing a sustainable and systematic digital archive system, through the investigation of early foreign missionaries' resources and in-depth interviews of experts. The study covers the period of 1800s to 1910, that is from the beginning of Protestant missionaries entering into Korea until the start of the Japanese annexation in 1910.

Traditional village forests in Jeju Island represent unique cultural landscape with a history of more than several hundred years as a national cultural asset in Korea. In this paper, the characteristics and meaning of traditional village forests in Jeju Island was compared with the Dangsan and Bibo forests at inland. There are 368 Oreums, parasitic volcano, and 391 shrines of Dang(Divine place) in Jeju. Life, culture and tradition of rural villages are all connected with the Dang and Oreum in Jeju. It has been found from this study that the village in Jeju were established as a cultural landscape on the surface of natural landscape. The features of traditional villages focused on the Dang and Oreum in Jeju Island were similar to the Dangsan and Bibo forestsat inland villages. The Oreum represents mountain and the Pojedan forest is newly found in Sangmyung-ri. The seashore areas are covered by vaocanic rocks in Jeju and large scale windbreaks are hardly found. The stone tower at Sinheung-ri built for blocking sand movement represents Bibo forest. The special attribute of the Dang in Jeju is that it is close to real life and believers are still remain. In 2009, the Jeju Chilmeoridang Yeongdeunggut ritual was nominated as an Intangible Cultural Heritage of Humanity by UNESCO. The shrine of Dang, however, has been degraded fast by construction of seashore road and Jeju Olle trail path. As for the world cultural heritage discussed at international conferences, it is important that there is sustainability on the right to enjoy cultural heritage. Integrated efforts from local residents, local governments and national government are needed to set up a management scheme for the Dang culture. Rural villages in Jeju with the Dang and Oreum are expected to get an international attention as to have traditional cultural landscapes of Korea.

The traditional laws of Korea have undergone various stages of development over time. This includes the voluntary standards of the clean society. Korea's traditional legal systems, ranging from those of the Goryeo(高麗) to those of the Republic of Korea, have taken Confucian Phiosophy as their major ideological bases. At the center of these Confucian ideals, particularly in regards to pre-Qin Confucian Philosophy(先秦儒家思想) from where these ideals originated, lie the core ideals which emphasize the responsibility of each individual regardless of the social status(正名), the needs for a democracy in which people are empower and guide the state(民本), the importance of reigning with benevolence, moral excellence, and rite (仁義), and the differential love centered on kinship and humanity(親親愛人). These were the ideas as set forth by Confucius(孔子), Mencius(孟子) and Xun Zi(荀子). The current laws of Korea, especially in regards to the Constitution and the Civil and Criminal Laws, include a number of provisions that contain the Confucian Ideas of Law. The Constitution, in particular, which is also supported by the judgement of the Constitution Court, reflects several core Confucian ideals including filial duty (孝) and respect for ascendants and the traditional culture. The Court also suggested the two important standards of the constitutional legitimacy of the Traditional Culture. One is 'Age Compatibility (時代 適合性)', the other is 'Manifested Universally Validity(現在的 普遍妥當性)'. So we have burdened with the reestablishment of the Universal Ethics of the Confucian Ideology.

The results of ground vegetation experiment conducted at completely denuded forestland in the mudstone region are summerized as follows: On the reaults of soiling quantity the effect of soiling was observed where depth of soiling over 10 cm was practiced, and a plot where treated with 15cm soiling and without fertilizer showed poor growth and it was even worser than the plot where soiling was practiced only 1 cm in thikness but applied adequate amount of fertilizers. The depth of slits between 30cm and 40cm showed no significant difference in the effect. A plot where covered with vegetation bag showed somewhat better results in seed loss and early growth but no differences observed in the fall result over the none covered plot. And then, it is recommendable to have soiling over 10cm in thikness with slit of 30cm and 30cm in depth and to apply 30 gram of fertilizer (22;22:11, 50 gram) per slit. On various soiling materials trial there were no striking differences in the effect of soiling between weathered granite soil, wheathered tuffs soil and weathered mudstone soil. In the treatment with various green materials, a plot treated with straw mat showed a significant difference at 1 percent. The results show that weathered mudstone soil is effective to use as soiling materials and straw mat treatment was better. On forest fertilization trial, in the mudstone region where red and black pine trees already existing at a rate of 2,000-3,000 trees per hectare had applied 110kg of compound fertilizers (9:12:3 and 22:22:11) per hectare basis in terms of plant nutrient. As a result, the difference in effect between the compound fertilizers was not found however the leaf color and leaf length of the fertilizer added plot showed darker and longer at 30 percent over the no fertilizer received plot. Compound fertilizers, 14:37:12 and 9:12:3 were applied to alder trees at a rate of 20 gram and 40 gram per tree in terms of plant nutrient and a remarkable growth accelerantion was observed where 40 grams of plant nutrient applied. The effect difference between the compound fertilizers was not found. On investigation of tree root elongation, forty years old red pine trees showed only 15cm tap root elongation through mudstone while black pine had 23 cm tap root elongation. The total length of supporting root elongtion of red and black pines showed 20 and 13 meters, respectively. The tap roots of Black locusts were not able to elongate through mudstone, however, the supporting roots tended to develop to the underneath of pine tree where some moisture content is available. Black locusts And grown on the residual soil of mudstone normally die between 8 to 10 years. The red pine trees show flat in tree shape while black pine had triangle in the shape. With the results it can be said that in an artificial reforestation in denuded forest land of the mudstone region the adequate slit and enough amount of fertiliizer application must be provided for the succesful performance of the program. On integrated experimental results of 1972. for the establishment of ground vegetation on the completely denuded forest land in mudstone region, soiling could be effectively practiced with weathered mudstone soil and it would not specially necessiate to have either weathered granite or tuffssoil for the soiling. And the soiling depth should be more than 10 cm in thickness. Among green materials used the straw mat proved to be the most effective reatment. Three major factors which enable to establish ground vegetation by the shortest period of time: A. Physical improvement of soil is necessary to breakdown of the horizontal cracks sushas Slit, contour line plot, seeding hole and etc., and soiling with weathered mudstone soil. B. Chemical improvement of soil: is needed sufficient amount of fertilizer application 300~400kg ha, $N+P_2O_5+K_2O$), and increased production of ground covering and expedite resolution of the vegetation (ground vegetation, fallen leaves and twigs). C. Complete establishment of the basic structure for the erosion control (Prevention of surface soil erosion)

The followings are the results of the study on industrial accidents occurred at 12 factories manufacturing metal products during the period of 2 years from January 1980 to December 1981 in the area of Yong-Dung-Po in Seoul. The results of the study are as follows: 1. The incidence rate of industrial injuries was 45.7 per 1,000 workers of the sample group and the rate of male (54.0) was three times higher than that of female (17.5). 2. In age groups, the highest rate was observed in the group of under 19 years old with 83.5, while the lowest in the group of 40s. 3. It was found that those who had short term of work experience produced a higher rate of injuries, particularly, the group of workers with less than 1 year of experience showed the highest rate of it as 48.1%. 4. In working time, the highest incidence rate occurred 3 and 7 hours after the beginning of their working showing the rate of 6.0 and 6.1 per 1,000 workers, respectively. 5. The highest incidence rate was observed on Monday as 8.4 per 1,000 workers, and it was 18.3% in aspect of the days of a week. 6. In aspect of the months of a year, the highest incidence was observed on July 1,000 workers and the next was on March as 4.8. These figures account for 11.8% of total occurrence in respective month. as 5. 4 per and 10.5% 7. In causes of injuries, the accident caused by power driven machinery showed the highest rate with 37.5%, the second was due to handling without machinery with 17.2%, and the third was due to falling objects with 14.2%, and striking against objects with 10.2%, and so on. 8. By parts of the body affected, the most injuries 84.3% of them occurred on both upper and lower extremities with the rate of 58.8% for the former and 25.5% for the latter. Fingers were most frequently injured with a rate of 40.3%. Comparing the sites of extremities affected, rate of injuries on the right side was 55.0% and 45.0% on the left side. 9. In the nature of injury, laceration and open wound were the highest with 34. 0%, the next was fracture and dislocation with 31. 9%, and sprain was the third with 8.1%. 10. On the duration of treatment, it lasted less than one month in 68.9% of the injured cases, of which 14.5% of the cases were recovered within 2 weeks, and 54.4% of them were treated more than 2 weeks. And the duration of the treatment tended to be prolonged in larger industries. 11. The ratio of insured accidents to uninsured accidents was 1 to 4.7.

In a case in which National Health Insurance Corporation (NHIC) pays medical care expenses to a victim of a traffic accident resulting in injury or death and asks the assailant for compensation of its share in the medical care expenses, as the precedent treats the subrogation of a claim set by National Health Insurance Act the same as that set by Industrial Accident Compensation Insurance Act, it draws the range of its compensation from the range of deduction, according to the principle of deduction after offsetting and acknowledges the compensation of all medical care expenses borne by the NHIC, within the amount of compensation claimed by the victim. However, both the National Health Insurance Act and the Industrial Accident Compensation Insurance Act are laws that regulate social insurance, but medical care expenses in the National Health Insurance Act have a character of 'an underinsurance that fixes the ratio of indemnification,' while insurance benefit on the Industrial Accident Compensation Insurance Act has a character of full insurance, or focuses on helping the insured that suffered an industrial accident lead a life, approximate to that in the past, regardless of the amount of damages according to its character of social insurance. Therefore, there is no reason to treat the subrogation of a claim on the National Health Insurance Act the same as that on the Industrial Accident Compensation Insurance Act. Since the insured loses the right of claim acquired by the insurer by subrogation in return for receiving a receipt, there is no benefit from receiving insurance in the range. Thus, in a suit in which the insured seeks compensation for damages from the assailant, there is no room for the application of the legal principle of offset of profits and losses, and the range of subrogation of a claim or the amount of deduction from compensation should be decided by the contract between the persons directly involved or a related law. Therefore, it is not reasonable that the precedent draws the range of the NHIC's compensation from the principle of deduction after offsetting. To interpret Clause 1, Article 58 of the National Health Insurance Act that sets the range of the NHIC's compensation uniformly and systematically in combination with Clause 2 of the same article that sets the range of exemption, if the compensation is made first, it is reasonable to fix the range of the NHIC's compensation by multiplying the medical care expenses paid by the ratio of the assailant's liability. This is contrasted with the range of the Korea Labor Welfare Corporation's compensation which covers the total amount of the claim of the insured within the insurance benefit paid in the interpretation of Clauses 1 and 2, Article 87 of the Industrial Accident Compensation Insurance Act. In the meantime, there are doubts about why the profit should be deducted from the amount of compensation claimed, though it is enough for the principle of deduction after offsetting that the precedent took as the premise in judging the range of the NHIC's compensation to deduct the profit made by the victim from the amount of damages, so as to achieve the goal of not attributing profit more than the amount of damage to a victim; whether it is reasonable to attribute all the profit made by the victim to the assailant, while the damages suffered by the victim are distributed fairly; and whether there is concrete validity in actual cases. Therefore, the legal principle of the precedent concerning the range of the NHIC's compensation and the legal principle of the precedent following the principle of deduction after offsetting should be reconsidered.
