최근 들어 발생하는 청소년범죄를 살펴보면, 청소년들이 저질렀다고 믿기 어려울 정도로 잔인하고, 흉폭화되어 있으며, 지능화되어 사회에 심각한 물의를 일으키고 있다. 이러한 청소년범죄는 부모와의 관계 가정환경의 영향에 의한 가정적 요인과 학교생활의 부적응 비행친구와의 접촉에 의한 학교 요인, 주변유해 환경 지역 주변에 의한 지역사회적 요인에 의해 범죄를 저지른다고 하였다. 실제 통계자료에서 청소년범죄는 2005년을 기점으로 다시 증가하고 있으며, 날이 갈수록 저연령화 되어가고 있으며, 강력범죄로 증가비율이 높은 것으로 나타났다. 이러한 청소년범죄를 예방하기 위해서는 가정, 학교, 지역사회가 서로 협력하여 지속적인 대안 마련이 필요하다. 경찰은 법 제도의 정비를 비롯하여, 청소년 관련기관의 협력증대, 유해환경제거 활동 등과 같은 비행청소년 선도 프로그램을 개선해야 한다. 오늘날 청소년범죄는 단순히 경찰활동상의 문제가 아니라 학교-경찰 연계 프로그램, 지역사회-경찰 연계프로그램과 같이 종합적인 대책마련과 관계당국의 적극적인 의지가 필요하다.

Recently, it appears several counterproposals about desirable figures of urban architecture. All of them proposes 'publicity' with cohernt tendency. The reason why it concentrates quantitative expansion of city without united design by urban plannar is that neglect quality values of city. As a solution of poor environment, there cue out the various efforts, about problem of each building, problem of city space, problem of laws and so forth. The reason why necessity of public space was embossed in that architecture extend the activity of citizen and make up the city space. But, each building pursues the private interest, so it is difficult to secure a public space with a high hand. Thus, architecture law has been revised in 1991 and bring the system of open space to match up the publicity and the private interest. Actually, western country brought it and obtained excellent results. While quantity of open space have increased since 1991, a lot of problems revealed in real usage and quality. By means of problem's solution, this study focus on the diversion of recognition for necessity of various open space. In result, on the occasion of approach and openess, except for several building, most glass a facade and the pedestrian can approach easily. Moreover, office buildings near the subway station connected with their low floor. So, the office buildings give openess to pedestrian and a people can approach easily to the buildings. On the occasion of amenity, most have bank and lobby on the first floor and have facilities on the underground floor. It leave open. But the reason why they have bank and lobby is that the space is dry and boring(without elements of nature and rest space). Hence, to make a space full of vitality, it have to plan various design elements and facilities. First of all, plan of indoor public space have to make up facility for the public interest. This study is basic investigation for necessity of indoor public space and through the survey of office buildings, it analyze the character of plan and find out the method of publicity's realization.

Objective : The aim of this study was to assess the safety and efficacy of radiation-sterilized allografts of iliac bone and fascia lata from cadaver specimens to repair skull base defects after transsphenoidal surgery. Methods : Between May 2009 and January 2010, 31 consecutive patients underwent endonasal transsphenoidal surgery and all patients received sellar reconstruction using allografts following tumor removal. The allografts were obtained from the local tissue bank and harvested from cadaver donors. The specimens used in our approach were tensor fascia lata and the flat area of iliac bone. For preparation, allografts were treated with gamma irradiation after routine screening by culture, and then stored at $-70^{\circ}C$. Results : The mean follow-up period after surgery was 12.6 months (range, 7.4-16 months). Overall, postoperative cerebrospinal fluid (CSF) leaks occurred in three patients (9.7%) and postoperative meningitis in one patient (3.2%). There was no definitive evidence of wound infection at the routine postoperative follow-up examination or during re-do surgery in three patients. Postoperative meningitis in one patient was improved with the use of antibiotics and prolonged CSF diversion. Conclusion : We suggest that allograft materials can be a feasible alternative to autologous tissue grafts for sellar reconstruction following transsphenoidal surgery under selected circumstances such as no or little intraoperative CSF leaks.

합리적 통행경로는 "경로를 노드 또는 링크의 순서로 표현할 때, 경로를 구성하는 노드의 반복은 존재해도 링크의 반복은 존재하지 않는다"는 원리에 근거한다. 최적경로 탐색과정에서 합리적 통행현상을 포함하는 방법은 링크로 구성된 표지(Link-Based Label)를 적용하는 방안이 적용하기 용이하다. 링크표지를 활용하는 경우 링크의 중복 표현을 허용되지 않는 상황에서 노드의 중복표현이 가능하여 합리적인 통행을 원칙적으로 보장될 뿐만 아니라 목적지에서 출발지로 경로를 역 추적(Backward Trace)하는 과정에서 전 링크(Pvevious Link)의 단일정보만 이용하므로 Bellman의 최적원리(Optimality Condition)에 의한 최적해(Optimal Solution)가 보장된다. 본 연구는 다수의 경로를 선정함에 있어 합리적 통행행태를 고려하기 위한 링크표지고정방식(Link-Based Label Setting)을 제안한다. 기존에 표지고정(Label Setting)을 기반으로 제안되었던 노드기반 다수경로알고리즘을 기반으로 링크표지로 전환하는 방안을 개발한다. 또한 알고리즘의 대규모 교통망에 적용한 수행결과를 통해 대안경로정보제공을 위한 현실적용의 문제점을 도출하고, 도로의 연속주행을 보장하려는 운전자의 경로선택행태를 반영하는 방안에 대해 검토한다.

Mobile games have emerged as the most innovative entertainment technology, adding new revenue streams, taking advantage of the potential of wireless applications and service offerings. Mobile games, like any other types of computer game, offer a unique value for users in providing an exciting digital experience in virtual worlds. Players can become empowered through the development of new characters and strategies within games to achieve rewarding successes against the computers and other players. The overall trend for mobile games is towards bigger, more colorful, more involving and exciting contents, which will build upon the developing capabilities of mobile phones and networks in order to bring new styles, concepts and experiences of game play to the users. In this paper, we attempt to investigate the demographic factors which play critical roles in determining the level of playing times; classify mobile gamers based on their motives for playing games; and empirically test differences in their demographic factors and mobile game usage. Statistical results show that significant differences in playing times exist, depending upon their age, gender, mobile device, mobile phone usage, mobile game experiences, and preferred games genres. Applying Factor analysis, we have identified Escape, Social interaction, Challenge and Competition, Fantasy, Diversion and Relaxation, Ease of Accessibility as key motivators for playing mobile games. Additional cluster analysis shows that the categorization of gamers, according to their usage habits and the key motivators for playing, can be made as follows: M-gamers, Multi-gamers and Communication-focused gamers. Further correlation of these grouping with socio-economic data shows the significant differences in gaming habits and patterns of mobile phone use.

Objective : Hydrocephalus is a common sequelae of aneurysmal subarachnoid hemorrhage (SAH) and patients who develop hydrocephalus after SAH typically have a worse prognosis than those who do not. This study was designed to identify factors predictive of shunt-dependent chronic hydrocephalus among patients with aneurysmal SAH, and patients who require permanent cerebrospinal fluid diversion. Methods : Seven-hundred-and-thirty-four patients with aneurysmal SAH who were treated surgically between 1990 and 2006 were retrospectively studied. Three stages of hydrocephalus have been categorized in this paper, i.e., acute (0-3 days after SAH), subacute (4-13 days after SAH), chronic (${\geqq}14$ days after SAH). Criteria indicating the occurrence of hydrocephalus were the presence of significantly enlarged temporal horns or ratio of frontal horn to maximal biparietal diameter more than 30% in computerized tomography. Results : Overall, 66 of the 734 patients (8.9%) underwent shunting procedures for the treatment of chronic hydrocephalus. Statistically significant associations among the following factors and shunt-dependent chronic hydrocephalus were observed. (1) Increased age (p < 0.05), (2) poor Hunt and Hess grade at admission (p < 0.05), (3) intraventricular hemorrhage (p < 0.05), (4) Fisher grade III, IV at admission (p < 0.05), (5) radiological hydrocephalus at admission (p < 0.05), and (6) post surgery meningitis (p < 0.05) did affect development of chronic hydrocephalus. However the presence of intracerebral hemorrhage, multiple aneurysms, vasospasm, and gender did not influence the development of shunt-dependent chronic hydrocephalus. In addition, the location of the ruptured aneurysms in posterior cerebral circulation did not show significant correlation of development of shunt-dependent chronic hydrocephalus. Conclusion : Hydrocephalus after aneurysmal subarachnoid hemorrhage seems to have a multifactorial etiology. Understanding predisposing factors related to the shunt-dependent chronic hydrocephalus may help to guide neurosurgeons for better treatment outcomes.

The anomalous pulmonary venous return of the entire left lung was an extremely rare congenital anomaly. The reported surgical experience with correction of this disorder was limited. The 3-year-old female patient underwent an operation upon the unilateral total anomalous pulmonary venous return from the left lung, in which the left superior pulmonary vein drained into innominate vein and the left inferior pulmonary vein into the coronary sinus, in Yeungnam University Hospital. The symptoms were nonspecific except frequent upper respiratory infection. Cyanosis was not seen. On auscultatory findings, a grade 2/6 systolic ejection murmur was audible over left second intercostal space of left sternal border and second heart sound had an increased pulmonary component which was widely splitted. The electrocardiogram demonstrated a right ventricular hypertrophy and right axis deviation and chest X-ray showed slightly increased pulmonary vascularity and bulged pulmonary conus. The echocardiogram demonstrated increased right atrial, ventricular, and pulmonary arterial dimension, and also secundum atrial septal defect and enlarged coronary sinus. The cardiac catheterization confirmed the left-to-right with a Qp/Qs of 2.0: 1 and oxygen step-up was seen in pulmonary artery, right ventricle, right atrium, and left innominate vein, and the catheter was not been introduced into the left pulmonary vein. A median sternotomy incision was done. Left superior pulmonary vein was drained to the innominate vein through anomalous vertical vein and the left inferior pulmonary vein drained to right atrium through the coronary sinus. The diversion of the left inferior pulmonary vein to posterior wall of left atrium was done after division in the proximity of coronary sinus. The anomalous vertical vein was diverted to base of left atrial auricle and then a atrial septal defect was sutured directly. The postoperative course was uneventful and she was discharged on the eleventh postoperative day. In the postoperative follow-up-2 months, she has been well without specific problems.

The purpose of this research was to develop a methodology to determine whether conjunctive surface water and groundwater management could significantly reduce deficits in a river basin with a relatively limited alluvial aquifer. The Geum River basin is one of major river basins in South Korea. The upper region of the Geum River basin is typical of many river basins in Korea where the shape of river basin is narrow with small alluvial aquifer depths from 10m to 20m and where most of the groundwater pumped comes quickly from the steamflow. The basin has two surface reservoirs, Daecheong and Yongdam. The most recent reservoir, Yongdam, provides water to a trans-basin diversion, and therefore reduces the water resources available in the Geum River basin. After the completion of Yongdam reservoir, the reduced water supply in the Geum basin resulted in increasing conflicts between downstream water needs and required instream flows, particularly during the low flow season. Historically, the operation of groundwater pumping has had limited control and is administered separately from surface water diversions. Given the limited size of the alluvial aquifer, it is apparent that groundwater pumping is essentially taking its water from the stream. Therefore, the operation of the surface water withdrawals and groundwater pumping must be considered together. The major component of the conjunction water management in this study is a goal-programmin g based optimization model that simultaneously considers surface water withdrawals, groundwater pumping and instream flow requirements. A 10-day time step is used in the model. The interactions between groundwater pumping and the stream are handled through the use of response and lag coefficients. The impacts of pumping on streamflow are considered for multiple time periods. The model is formulated as a linear goal-programming problem that is solved with the commercial LINGO optimization software package.
