The purpose of this study was to analyze empirically influential factors related to the recovery of people with a mental disorder and also the moderating effects of family resilience. For this purpose, the investigator developed a research model that took into consideration both the positive and negative elements of individual and social factors based on the ecological, psychological, social, and ecosystem perspectives in previous studies and checked their causal effects and the moderating effects of family resilience in statistical significance. The subjects include 112 clients at an institution for people with a mental disorder. Data was collected with an interview based on a structured questionnaire. Collected data was put to the multiple regression analysis. The analysis results show that there was statistical significance in self-esteem, social stigma, and social support excluding symptoms and that the moderating effects of family resilience had positive(+) synergistic effects only on self-esteem and social support. Based on these results, the study made proposals about practice strategies including the establishment of internal and external support systems to make an effective approach to recovery and the systemization of family resilience and supportive strategies to promote the smooth recovery of people with a mental disorder through the reinforcement of programs related to the confirmed positive elements of self-esteem and social support.

지하수 관측이란 지하수위 하강, 수질오염 등 지하수 장해로부터 지하수를 보전 관리하고 대책을 수립하기 위하여 정기적 및 장기적으로 지하수위, 수질 등 부존된 지하수 특성의 상태와 변화하는 추이를 관찰하여 측정하는 행위를 말한다. 지하수는 지하의 보이지 않는 지층구조에서 매우 천천히 유동하므로 수위하강 및 수질오염 발생을 늦게 인지할 경우 원상회복이 불가능할 수 있고, 지하수 장해를 인지한 이후의 대처과정에서도 기존의 관측자료가 없거나 부족할 경우에는 원인분석과 대책수립이 지연되거나 불가능할 수 있으므로 지하수관리에 있어 관측정호를 설치하고 정기적으로 지하수의 부존 및 유동특성, 배경수질 등의 지하수 관측은 기본적이며 필수적인 요소이다. 따라서 지하수 관측망을 설치하고 운영하기 위해서는 관측 목적을 명확히 정의하고 관측 프로그램이 이를 만족시키도록 구성되어야하며 시간적, 공간적으로 지하수가 변동되는 것을 고려하여 관측 지역 대수층의 유형과 특성 등이 완전히 파악되어야 한다. 필요시 기존 관정을 활용하여 관측하며 관측 항목, 관측 유형, 위치측량 및 관측 주기 등은 관측의 목적에 부합되도록 한다. 관측 데이터의 생성, 전송 및 분석 진행과정 등이 완벽하게 정립되어 데이터의 생성에서부터 활용까지 체계화되어야 하고 지하수와 지표수는 연계된 단일 수자원으로서 지하수 관측은 지표수 관측과 연계되어 설계되고 분석되어야 한다. 또한 취득된 데이터의 정확성은 지속적으로 검토 확인되어야 하며 전문가의 능력을 활용하여 관련 자료의 분석이 이루어지고 데이터의 정도를 높이기 위한 후속조치들이 병행되어야 한다. 그리고 지하수위, 수질 등 관측 자료가 자연적인 지하수 유동 체계에 의하여 변화되는 것이라고 인식될 경우에는 관측 시스템 전반을 재평가하여 보다 효율적인 관측 시스템으로 발전시켜야 한다.

In client-server computing environments, update transactions of spatial data have the following characteristics. First, a transaction to update maps needs interactive work, and therefore it nay take a long time to finish. Second, a long transaction should be allowed to read the dirty data to enhance parallelism of executing concurrent transactions. when %he transaction is rolled back, it should guarantee the cascading rollback of all of the dependent transactions. Finally, two spatial objects may have a weak dependency constraint, called the spatial relationship, based on geometric topology. The existing recovery approaches cannot be directly applied to this environment, due to the high rollback cost and the overhead of cascading rollbacks. Furthermore, the previous approaches cannot guarantee the data integrity because the spatial relationship, which is a new consistency constraint of spatial data, is not considered. This paper presents new recovery schemes for update transactions of spatial data. To guarantee the data integrity, this paper defines recovery dependency as a rendition of cascading rollbacks. The partial-rollback is alto suggested to solve the problem of high rollback cost. The recovery schemes proposed in this paper can remove the unnecessary cascading rollbacks by using undo-delta, partial -redo and partial-undo. Finally, the schemes are performed to ensure the correctness.

뽕잎의 지금까지 박ㄹ혀진 생리활성은 중금속 흡착과 해독효과, 황산화 효과, 혈중지질 억제효과 및 혈당강하 효과를 들 수 있는데, 요약하면 다음과 같다. 1) 뽕잎이 Cd과 Pb같은 중금속에 대한 흡착 및 해독작용에 미치는 영향을 조사해 본 결과, 납중독으로 인하여 감소된 Hb와 Haematocritcl가 뽕잎 투여로 증가되었고 특히 gpa합성에 관여하는 DALAD효소 활성을 증가시켰다. 또한 뇨로의 Pb의 배설 효과가 뽕잎 투여로 증진되었으며 각 조직으로의 Pb축적을 감소시켰다. Cdwndehr으로 중독시킨 흰쥐에서도 감소된 Hd와 Haematocritcl가 뽕잎투여로 증가되었고, 특히 간조직 중의 Cd축적을 61%로 감소시켜 유의성있게 감소시켰다. 또한 뽕잎투여로 인하여 변으로의 Cd의 배설효과는 38%였고 이는 녹차투여 효솨보다는 낮은 수준이었다. 2)뽕잎의 향산화 효과는 녹차와 거의 비슷하였고 특히 혐기 처리함으로써 그 활성이 증가하였다. 또한 뽕잎중의 황산화 활성 성분은 10여종 flavonoidfb 이었고 그 중 quercetin이 가장 높은 황산화 활성을 나타냈다. 특히 dlavonidfb 화합물 중 kaempferol계열의 화합뭉이 황산화 효과가 높음을 알수 있었다. 3) 뽕잎의 고지혈 억제작용에 미치는 영향을 알아본 결과 뽕잎은 혈중 총 콜레스테롤이 차지하는 비율을 보였고 특히 혈중 중성지질 함량을 감소시킴으로써 정상의 80%수준까지 회복시켰다. 또한 콜레스테롤 생합성에 관여하는 효소활성을 뽕잎의 메탄올 추출물 중 물분획뭉이 59.9%수준으로 억제시켰고 지방분해효소 활성은 유의적인 수준은 아니었지만 16% 증가시켰다. 4) 뽕잎의 혈당강하 효과는 뽕잎을 질소가스를 이용하여 혐기처리하는 경우 유의적으로 그 효과가 증강되었다. 또한 뽕잎은 대조약물인 acarbose의 10배 용량에서 대조약물보다 23% 이상의 혈당강하 효과를 나타냈다. 이들의 혈당강하 효과는 같은 농도에서 인슐린 함량을 27%회복시켰으며 특히 surcrose와 maltose와 같은 이당류를 부하시켰을 때 혈당 강하 효과는 유의적이었다. 이는 뽕잎의 혈당강화 효과는 인슐린생합성 증가에 의한 것보다는 glucosidase의 활성을 억제시키는 기전이 더 많이 관여하는 것으로 판단할수 있었다. 또한 뽕잎 중의 혈당강하 성분으로 알려진 1-deoxynojirimycin 함량은 혐기처리로 인하여 그 함량이 5%정도 증가됨을 확인할 수 있었다. 이러한 뽕잎의 생리활성 결과에 기초할 때, 뽕잎은 고지혈증을 포함한 성인병 질환의 예방과 회복에 관련되는 조절기능을 생체에 충분히 발휘할수 있는 기능성 식품의 중요한 자원으로 이용될 수 있으리라 판단된다.

Criminal Mediation System in Korea, it did pilot operation by Crime Victim Support Centers such as Daejeon and other two District Prosecutors' Office in April 2006. And starting 2007, Crime Victim Support Centers and Criminal Mediation System conducted from 57 District Attorney's Office and Branch Offices and now 2016, Criminal Mediation System is operated in all the District Attorney's Office. On the other hand, the Attorney General's Office established the 'Criminal mediation practical operating instructions' in October 2009 and created its legal basis at "Crime Victims Protection Act" in September 2010. It seems that the criminal mediation have to operate as the direction for supporting crime victims recovery. However, it seems that the overall infrastructure of the criminal mediation system is built. But I have experienced this through G Attorney's Office as a Criminal mediator activity from 2007 to 2016 now, some issues have emerged such as weak on personal safety in criminal mediation room, etc. Thus, in this paper, I will examine the problems about this and propose improvements of criminal mediation system to fit the practical criminal mediation.

In recent years, health care cost containment concerns have resulted in an increase in outpatient (or same-day) surgery. Many procedures previously performed on an inpatient surgery basis have been shifted to outpatient settings. Anesthesia for outpatient surgery is exactly the same as inpatient anesthesia, except that the primary concern is the selection of patients who can be discharged safely on the day of surgery. The anesthesiologist should have a sound rational basis for choice of pharmacologic agents that are geared to expeditious patient discharge from the hospital. Cost concerns aside, outpatient surgery has many additional advantages in the pediatric setting. It minimizes the length of time the child is hospitalized, decreases separation anxiety, promotes parental involvement in the child's postoperative care in the more congenial environment of home, and decreases risk of nosocomial infection and iatrogenic illness.

This study aims at analyzing the global trend of standardization in the field of Industrial Security through ISO/TC 292. It covers broad areas from risk management for industrial property protection and loss prevention through supply chain security, product and document fraud and counterfeiting countermeasures and control and community resilience. It also explores the historical background of the standardization in the security field, how ISO TC 292 came out as a leading group in order to standardize relevant security management systems. TC 292 deals with terminology, general security-related standards and supply chain security management. One of the major findings from this analysis is that security targets and threats are diversified and so organizations like enterprises should have proper flexibility to adapt themselves to new security environment and take appropriate resilience system to cope with the threats and incidents. Also the ISO standardization requires public or private entities to take holistic approaches in security management. Finally, it was found that South Korea has to prepare for this global trend of standardization in this field so that ISO certification market demand and the requirements for transnational trades can be well met.

Disability Discrimination Act(DDA) is generally recognized as the institutional frame to realize social model of disability. However social model is not automatically realized via the enactment of DDA. The realization of social model is influenced by various factors among which the definition of disability in DDA is very important factor. Paradoxically definitions of disability based on social model may push DDA into contradictory situation. This is caused by the fact that on the one hand definitions of based on social model exclude impairment and on the other hand they mixes characteristics and treatment. Because of these, when definitions of disability based on social model is reflected into definitions of disability in DDA, they may not be helpful to realize social model against original intention of advocates of the model. We can consider two approaches to resolve this paradox; one is to partially reform current definition of disability in DDA, the other is to totally amend current definition of disability. The former may pragmatic and worth to pursue but it cannot solve fundamental problems and may cause some new problems. The most consistent resolution with social model is to amend current definitions of disability into radically new one which excludes substantial limits and definition of disabled person from definition of disability. This new definition may called characteristics based definition or impairment based definition. Some people may think this new definition as one based on medical model but it is not. What we need is not to carve definition of disability based on social model into DDA but to make institutional frame for DDA to operate without contradictions and to develop social model of both impairment and disability. This model which does not exclude impairment could takes part in realization of the social model disability.

Background: In patients with coronary artery disease, dysfunctional hypoperfused myocardium at rest may represent either nonviable or viable hibernating myocardium. Two-dimensional echocardiography can detect regional wall motion abnormalities resulting from myocardial ischemia by dobutamine infusion. The purpose of the present study was to identify the prediction of improvement of regional left ventricular(LV) function after surgical revascularization. Materials and methods: Sixteen patients with chronic regional LV dysfunction underwent dobutamine stress echocardiography(DSE) (dobutamine: baseline, 5, 10, 20$\mu$g/kg/min) before coronary artery bypass grafting(CABG) and underwent echocardiography at least 2 months after CABG. Results: All patients were male with mean age of 58 years ranging from 42 to 73 years. The mean LV ejection fraction was 41.8% with a range from 19% to 55%. During DSE, there were no complications, also, there were no operative morbidities or mortalities. Improvement of wall motion within the dysfunctional myocardium was found in 8(50%) of 16 patients in DSE. Among them, 6 patients(75%) showed functional recovery after CABG. Another 8 patients did not show improvement of wall motion in DSE. But among them, 3 patients(38%) showed functional recovery after CABG. 84 dysfunctional segments were found in 256 segments of 16 patients. Improvement of wall motion was found in 34 of 84 segments in DSE. Among them, 23 segments(74%) showed functional recovery after CABG. Another 53 segments did not show improvement of wall motion in DSE. But among them, 12 segments(23%) showed functional recovery after CABG. The sensitivity and specificity of DSE for the prediction of postoperative improvement of segmental wall motion were 66% and 84%, respectively. The positive and negative predictive value of DSE were 74% and 77%, respectively. In patients with chronic regional LV dysfunction, think that DSE is a good predictor of the improvement of dysfunctional segments after CABG.
