한국에서의 경찰제도는 국가경찰의 형태로 운영되어와 획일적이고 중앙집중식의 경찰활동에 대한 거부감이 전반적으로 있어왔다. 그러나 지역주민의 의사에 따른 자율규율에 의한 다원적 민주주의를 실현하고 국민의 기본권을 실질적으로 보장하기 위하여 지난 1995년 지방자치단체의 장과 지방의회 의원의 동시선거가 시행되어 온 이래 10여년이 흘렀다. 그러나 지방자치제도가 시행되기 이전부터 자치경찰제도에 대한 논의는 지속적으로 이루어져 왔다. 자치경찰제에 있어서 주요쟁점의 핵심사항은 자치경찰제를 도입하는 것의 득실관계라고 볼 것인데 이는 관점과 어느 측면에 중점을 둘 것인가에 따라 다르게 나타나게 된다. 지방자치의 존재 이유 중에는 주민 복지적 차원에서 주민의 안전보호가 중요한 부분을 차지하고 있다. 특히 자치경찰제는 수사권독립과 함께 지난 몇 대에 걸친 각 대통령의 선거공약이었기 때문에 노무현 정부 출범 이후 정부는 지방분권차원에서 정부혁신지방분권위원회에서 여러 가지 검토를 해 온 바 있다. 2004년 1월에 정부혁신지방분권위원회의 지방 분권과제 주요과제로 자치경찰제 방안을 검토하기 위해 위원, 관계 공무원 10명으로 자치경찰 T/F를 구성하여 운영한 이 후 자치경찰제 도입방안에 대하여 경찰정과 실시 단위 및 수행 사무 등 주요 쟁점에 대해 협의하면서 실천 가능한 방안을 마련하기 위해서 스페인, 프랑스, 이태리, 그리스 자치경찰기관을 현지 방문하여 외국 자치경찰 제도를 조사한 후 2004년 9월 중순에 자치경찰(안)을 발표하였다. 이 안은 크게 경찰을 사법경찰과 행정경찰로 구분하는 개념 하에 최초로 나온 자치경찰제에 대한 구체적 시행 안이라는 점에서 그 의의를 찾을 수 있을 것이나 지금까지의 기대수준에 과연 부응하는 안이 될 수 있을 것인가에 대한 의문이 제기되고 있다. 동 사안은 2005년 하반기에 시범적으로 시행하고 민선 4기 자치단체장이 출범하는 2006년 하반기에 본격적으로 시행될 것으로 발표하고 발표와 동시에 정부혁신지방분권위원회에서는 본 자치경찰제 기본방향과 법안제정의 원칙과 구체적인 내용에 대한 토론회를 개최하는 등 다양한 홍보를 하였으나 여러 가지 문제점으로 인하여 아직 시행되지 못하고 있다. 따라서 과연 이 안이 한국에서의 자치경찰제 시행에 효과적인 안인가 그렇지 않으면 대선공약을 지키기 위한 일종의 정치적 고려를 한 졸속적인 안이 아닌가에 대한 논란이 제기되고 있다. 지금까지 한국에서는 자치경찰에 대한 많은 토의가 있어 왔으나 이번에 제하고 있고 현재 지방자치단체에서 시행하고 있는 기존 법집행방식과 거의 차이가 없는 상태시된 안은 적어도 지금까지 논의되어왔던 제도와는 매우 생소한 자치경찰 제도를 근간으로 에서 ‘무늬만 자치경찰’ 이라는 비판이 일각에서 제기되고 있는 실정이다. 현재 자치단체에서 시행하고 있는 행정 경찰적 기능을 다소 보완하고 제복착용과 조직을 하나 더 만든 정도가 아닌가 하는 정도이다. 그러므로 본 연구에서는 정부혁신지방분권위원회에서 제시한 자치경찰제도(안)을 중심으로 자치경찰제도 운용의 목적 충족과 실질적인 효과의 측면에서 분석하고 바람직한 자치경찰제도의 운용에 대해 살펴본다.

The main objective of this study is to investigate the variation in the ignition characteristics of coals as a function of moisture content in a laminar flow reactor (LFR) equipped with a fuel moisture micro-supplier designed by the Pusan Clean Coal Center. The volatile ignition position and time were observed experimentally when a pulverized coal with moisture was fed into the LFR under burning conditions similar to those at the exit of the pulverizer and real boiler. The reaction-zone temperature along the centerline of the reactor was measured with a $70-{\mu}m$, R-type thermocouple. For different moisture contents, the volatile ignition position was determined based on an average of 15 to 20 images captured by a CCD camera using a proprietary image-processing technique. The reaction zone decreased proportionally as a function of the moisture content. As the moisture content increased, the volatile ignition positions were 2.92, 3.36, 3.96, and 4.65 mm corresponding to ignition times of 1.46, 1.68, 2.00, and 2.33 ms, respectively. These results indicate that the ignition position and time increased exponentially. We also calculated the ignition-delay time derived from the adiabatic thermal explosion. It showed a trend that was similar to that of the experimental data.

This study analyzed the distribution of the blood glucose level according to the fasting status. Moreover, a relationship was analyzed between fasting blood glucose level and glycemic control indicators. A total of 707 outpatients, who visited Dankook University Hospital, were included and classified into either the fasting group and the non-fasting group. The mean blood glucose level of each group was calculated and analyzed by sex, age, and clinic. In addition, blood glucose, HbA1c, fructosamine, and 1,5-AG were measured in 153 fasting health check-up patients, and the correlation between the blood glucose level and glycemic control indicators was evaluated. Blood glucose averages between the two groups (non-fasting 111.9 vs. fasting 103.6 mg/dL) were different (p<0.05); and the mean difference was lower in women (4.8 mg/dL) than in men (12.2 mg/dL). A significant difference of the median glucose values among the age groups was only observed in the non-fasting group (Kruskal-Wallis test, p<0.01), and not in the fasting group. A 1,5-Anhydroglucitol was estimated to be significantly correlated with the fast blood glucose level in the range of the criteria of impaired fasting glucose (IFG). We presented an assessment of the distribution of blood glucose level in accordance with the fasting status among outpatients, and estimated that 1,5-anhydroglucitol was well correlated with the fasting blood glucose than fructosamine and HbA1c, through the analysis of results of health screening subjects. It is suggested that the use of glycemic indicators that reflect short-term blood glucose control can be used together with the blood glucose measurement in the screening of diabetes mellitus.

This paper is to analyze citizens' consciousness on urban changes during the 1900s in the sectors of economy, politics and socio-culture of large cities in Korea, especially comparing them in Seoul, Daejeon, Daegu, and Kywangju. The items of questionnaire are drawn from theories on each sector of new urbanization of large city in Western countries, that is, that of post-Fordism, of urban governance, of post-modernism, and of sustainable city. Some major findings of this questionnaire analysis are as follows. First, on the change of large cities in general, citizens think that the sectors of spatial structure, and of socio-culture of the cities were changed more than those of urban economy and of urban politics. Secondly, in the sector of urban economy, citizens recognize that the obstructing factors of development, that is, the lack of regional capital and the absence of head-quarter of large firms, which seems to be resulted from uneven regional development in the previous periods were much more serious than others, while acknowledging the importance of high-tech industry. Thirdly, in the sector of urban politics, citizens think that the centralized structure of politics and of political parties was still problematic, while acknowledging the importance of entrepreneur mind of urban governor. Finally, in the sector of urban socio-culture, citizens emphasize the development of telecommunication, the popularization of private automobile and the increasing use of credit card, as three major factors which have exercised major impacts on the development of urban socio-culture.

The era of autonomous vehicles, which drive themselves and in whose operation the driver does not intervene, is fast approaching. The safety of autonomous vehicles can be guaranteed only if they recognize the road infrastructure. However, the road infrastructure consists of road safety facilities, traffic operation systems, and cross-sectional concerns, which include a variety of components, such as types, shapes, and sizes. Therefore, it is necessary to prioritize the road information. This study was conducted to select the priority with which the road infrastructure attributes should be acquired using the AHP (Analytical Hierarchy Process) method. The road infrastructure attributes were categorized into 2 levels, levels 1 and 2, which consisted of 3 and 26 types of attributes, respectively. As a result of the AHP analysis, it was found that the highest priorities of the road infrastructure are the road safety facilities, traffic operation systems and cross sectional concerns. Also, in level-2, the priorities of the safety barriers (road safety facilities), traffic signals (traffic operation systems), and the median (cross sectional) are the highest. Also, this study provides application examples of road infrastructure extraction with the Point Cloud. The results are expected to support the recognition of technology for autonomous vehicles.

The purpose of this study is to examine how the cultural aspects of the publication of literary collections have been changed from its time throughout the entire Joseon Dynasty. At the royal court in the early Joseon Dynasty, the need for publication of the literary collections has consistently arisen to preserve writings of the noted sages, and the Joseon government was also taking the lead and promoting the publication of the literary collections. From the 16th to the early 18th century, the publication was intensively made at the local governments led by local governors. From the 17th to the early to middle of the 18th century, the finances of local governments were limited with the changed taxation system, and there had been a dramatic decrease in the number of literary publication projects. On the other hand, with the sudden increase of the number of Seowons during the reign of King Sukjong, the focus of the literary publication was moved to Seowon from the 18th to the 19th century. After the enforcement of the Seowon Abolition Decree, the collections were still published at Seowons, however from the end of 19th century, the publication of literary collections had been explosively made by aristocrats who did not belong to the institution of Seowon or could not receive Seowon's support, which spreaded over the entire Yangban culture.

This study's purpose is to research the antioxidant power of Calaguala (Polypodium leucotomos, PL) as an oral supplement: Calaguala, a native of Central America, is a fern which belongs to the family polypodiaceae protecting the skin from the ultraviolet and active oxygen free radicals. The total 14 volunteers, each female 7 & male 7, were divided into 2 groups, then exposed to UV for 30 min after taking Calaguala and placebo. The total antioxidant capacity (TAC) was analyzed by taking the blood samples from anticubital vein 3 hours after UV exposure. First, Calaguala siginifcantly decreased the concentration of active oxygen free radicals 4 weeks later. The concentration of active oxygen free radical in PL group declined more than placebo group, when measured 30 min and 3 hours after UV exposure. Second, Calaguala did not significantly increase TAC 4 weeks later, but significantly decreased TAC 3 hours after exposure, when compared with placebo group. Now days, the photo allergy and photo aging caused by air pollution and ozone destruction have drastically increased, and thus the amount of UV radiation reaching the earth's surface increased. The increase of active free oxygen radicals resulted in accelerating the diseases and aging. The first superficial protecting protection by reflection & dispersion and the second body internal protection by taking oral photo antioxidant such as Calaguala should be continuously researched.

A star schema consists of a central fact table, which is surrounded by one or more dimension tables. Each row int the fact table contains a multi-part primary key(or a composite foreign key) along with one or more columns containing various facts about the data stored in the row Each of the composit foreign key components is related to a dimensional table. The combination of keys in the fact table creates a composite foreign key that is unique to the fact table record. The composite foreign key, however, is rarely unique to the fact table record in real-world applications, particularly in financial applications. In order to make the composite foreign key be the determinant in real-world application, some precalculation might be performed in the SQL relational database, and cached in the OLAP database. However, there are many drawbacks to this approach. In some cases, this approach might give users the wrong results. In this paper, an approach to fact table modeling and related MDX query composing, which can be used in real-world applications without performing any precalculation and gives users the correct results, is proposed.

The gold buckle excavated from Seogam-ri Tomb No. 9(National Treasure No. 189), one of the oldest gold artifacts discovered within the Korean Peninsula, was created using granulation techniques. The buckle is made with 22.8K gold sheets and features a decorative design with seven dragons in repousse metalwork. The outlines of the dragons and the edge of the buckle are finished with 23.8K gold wires and granules. Some curved sections of the buckle are also covered with an extra sheet of 23.8K gold, possibly added to repair defects discovered during production or thereafter. Gold wire used to render the dragon's nostrils is slightly lower in purity(23.3K) and was probably preferred in this case due to its increased hardness. As a result, the metal is better able to retain the complex shape of the dragons' nostrils, created by rolling gold wire into spirals. The buckle's gold granules are found in small, medium and large sizes and are presumed to have been bonded using copper. The foreheads and the bodies of the seven dragons are inset with turquoise and the eyes are decorated with red cinnabar/vermillion(HgS).

Generally, inappropriate driving conditions including geometric, traffic environmental, and driver psychological problems may be critical reasons of traffic accidents. Under this circumstance, various types of facilities have been installed to improve traffic safety by itself or as a set consisting of several other traffic safety facilities. In general, traffic accidents occur by several reasons combined rather than only a single reason, and thus the safety effect of the safety facilities cannot be simply analyzed with only a single improvement. For the study, traffic accident data on the roadway segments of interest are collected along with field survey data. For the analysis, various alternative analysis methods were evaluated in terms of assessing accident reduction from various types of traffic safety improvements. Among the alternative methods tested including simple before-and-after evaluation method, before-and-after evaluation yoked comparison, and Comparison Group (C-G) method, it was found that the C-G method is the most effective method for analyzing the traffic safety improvement effect. Adopting the C-G method, both single and multiple safety improvements were analyzed. The results from this study can potentially be applied to decide the best type of treatments to improve traffic safety as well as to measure the accident reduction effects from the treatments.
