신용리스크 관리에 해당하는 부도예측모형은 기업에 대한 신용평가라고도 볼 수 있으며 은행을 비롯한 금융기관의 신용평가모형의 기본 지식기반으로 새로운 인공지능 기술을 접목할 수 있는 유망한 분야로 손꼽히고 있다. 고도화된 모형의 실제 응용은 사용자의 수용도가 중요하나 부도예측모형의 경우, 금융전문가 혹은 고객에게 모형의 결과에 대한 설명이 요구되는 분야로 설명력이 없는 모형은 실제로 도입되고 사용자들에게 수용되기에는 어려움이 있다. 결국 모형의 결과에 대한 설명은 모형의 사용자에게 제공되는 것으로 사용자가 납득할 수 있는 설명을 제공하는 것이 모형에 대한 신뢰와 수용을 증진시킬 수 있다. 본 연구에서는 머신러닝 기반 모형에 설명력을 제고하는 방안으로 설명대상 인스턴스에 대하여 로컬영역에서의 설명을 제공하고자 한다. 이를 위해 설명대상의 로컬영역에 유전알고리즘(GA)을 이용하여 가상의 데이터포인트들을 생성한 후, 로컬 대리모델(surrogate model)로 연관규칙 알고리즘을 이용하여 설명대상에 대한 규칙기반 설명(rule-based explanation)을 생성한다. 해석 가능한 로컬 모델의 활용으로 설명을 제공하는 기존의 방법에서 더 나아가 본 연구는 부도예측모형에 이용된 재무변수의 특성을 반영하여 연관규칙으로 도출된 설명에 도메인 지식을 통합한다. 이를 통해 사용자에게 제공되는 규칙의 현실적 가능성(feasibility)을 확보하고 제공되는 설명의 이해와 수용을 제고하고자 한다. 본 연구에서는 대표적인 블랙박스 모형인 인공신경망 기반 부도예측모형을 기반으로 최신의 규칙기반 설명 방법인 Anchor와 비교하였다. 제안하는 방법은 인공신경망 뿐만 아니라 다른 머신러닝 모형에도 적용 가능한 방법(model-agonistic method)이다.

The Local Agenda21 is an action program of local dimension to realize of sustainable development. The citizen participation is prime issues and very important f3r successful practice of the Local Agenda21. The purpose of this research is to analyze the citizen participation problem and to suggest the improvement plan at the advanced course of the Local Agenda21. The research results are as follows; 1. The recognize of citizen about the Local Agenda21 is very low. Namely, the citizen of about 50% answered not to know about the Local Agenda21, 2. However, citizens showed the participation opinion to be very active by simple explanation about the Local Agenda21. 3. Also, citizens showed the result to be very affirmative in the environment problem consciousness investigation. Namely, citizens were recognizing the environment problem as the problem of the society synergic.

Background : This study was attempted to provide a basic information necessary for the development of measures evaluating perceived discomfort of the patients under local anesthesia and the developments of nursing intervention and nursing standard. Method : The study subjects were a convenience sample of 100 surgical patients under local anesthesia. The researcher visited the patients directly and explained the purpose of the study to them. Then they were asked to fill out questionnaires which were developed and structured by the researcher, under their prior permission. Out patient's data were collected at recovery room after operation. Results : Factor analysis on measures evaluating the patients under local anesthesia showed that the measures consisted of eight factors including "explanation", "humane treatment", "motion limitation", "pain", "no togetherness", "waiting", "the environment of operating room", and "unkindness". When analyzing each of the factors regarding their degree of contribution to perceived discomfort, it was found that "waiting" was highest in terms of the degree. According to general chara-cteristics of the sampled patients, the factor of "explanation" contributed to perceived discomfort more in male patients than female ones. Regarding parts of medical examination, the patients of otorhinolaryngology felt perceived discomfort most because of the factor of "pain". Conclusion : To relieve perceived discomfort the patients under local anesthesia require providing individually systematized nursing services which can reduce perceived discomfort according to each of the factors. In doing so, an unlimited attention and much effort should be given to realize CQI reaching the dimension of increase in comfort as well as decrease perceived discomfort.

In [1] L. Nirenberg constructed a famous example of a smooth vector field which have only the constant functions as solutions in an open subset of the plane. Explanations of this phenomenon have been proposed in Treves [3] and Sjostrand [2]. The explanation in [3] is related to the following so-called "local constancy principle".ple".uot;.

The 2018 local elections completely upended the composition of Busan's city council, with the council membership changing from being solidly and consistently conservative to being over 80% liberal. What explains this anomalous outcome? While existing literature suggests the outcome of the 2018 city council elections was the consequence of a combination of structural and strategic factors, such as the decline of regional voting, we argue that the individual-level evaluation of President Moon Jae-in is one of the primary factors driving this result. Although coattails effects are commonly considered in concurrent national legislative elections, the Presidentialized and nationalized politics of Korea makes it possible for Presidential elections to affect local elections as well. We assess our explanation through an analysis of repeated cross-sectional survey data collected just before the 2018 local elections. The results of the analysis show that support for the Democratic Party is very strongly predicted by individual-level evaluation of President Moon. When considered in the context of the timing of presidential and local elections, the results suggest that Presidential coattail effects are capable of destabilizing established political patterns, such as regional voting, if perhaps only in a sporadic and idiosyncratic fashion, depending on whether or not local elections are held early on in a President's term.

최근 통신업계에서는 축적된 빅데이터를 활용하여 고객의 특성을 이해하고 맞춤형 마케팅에 이용하려는 노력이 지속되어 왔다. 본 연구에서는 CatBoost 모델을 사용하여 이탈 가능성이 높은 고객을 예측하고 XAI(eXplainable Artificial Intelligence) 기법 중 하나인 SHAP을 적용하여 이탈에 영향을 미치는 요인을 설명하고자 하였다. SHAP의 global explanation 기법을 사용하여 특정 고객 segmentation 에 대한 이해력을 높이고, local explanation 기법을 사용하여 개별 고객에 대한 설명과 개인화 마케팅에 적용 가능성을 제시하였다. 본 연구는 기존의 이탈 예측모델인 블랙박스 모델이 갖는 한계점을 극복하고 고객의 특성을 이해하여 실제 비즈니스에 활용 가능성을 높였다는 점에서 의의를 가진다.

In existing method, research for landscape resource is driven by professional (or with the participation of local people at Tokenism level), and usually hinder local residents from reflecting their appreciations on the landscape resources in their own ways and eventually ends up with indistinguishable landscape planning. To avoid this, a profound understanding of what landscape they experience in their daily life and how they perceive it should be empirically analysed carefully. The purpose of this study is to apply walking behavior as a method to examine local residents' subjective perceptions and consider its usability. The researcher walked the site(Sucheongri) with the residents, carrying a GPS device, taking photographs of the landscape objects they described, and recording the relevant explanations. After gathering photographs and explanations which represent the research participants' individual subjective perception, the researcher analysed the explanation using open coding, based on grounded theory. By the analysis, 117 landscape objectives are identified and 18 reason factors for landscape perception were deduced from the explanation. Those factors could be classified as 'positive feeling inducing' and 'negative feeling inducing', and also as 'personal emotion based' and 'community based emotion'. By comparison between feeling map by conventional method and feeing map by new method, usability of new method was empirically reveled. Walking behavior makes it easier for researcher to get more abundant data in quantitative aspect and profound understanding with affection of respondent by allowing them to 'go beyond' the perceptions they remember. Finally new method with walking gives professionals a contextual understanding of a place and more resident-oriented plans and management on sites.

Recently, the twenty-first century is called "the age of localization and regionalization" in Korea. So, local government should need to keep balance between the existing administrative management and new management strategies based on CEO's mind in order to deal with the situation of such that(the age of localization and regionalization) and improve efficiency of public service. In addition, they build public buildings after that they should operate and maintain them regularly. However, Korea local governments have tried to run many projects to expand insufficient local finance that was only for profit oriented public projects without considering management. Therefore, this paper is a basic study to establish and suggest the reasonable operation plan for local government by examining and reviewing actual operation condition in the public buildings. With the evaluation method which is demanded from public construction management to introduce a civil management technique manages an investment mind standard and management basis of assessment, proposes 8 sides of financial affairs, real estate maintenance and facility management, achievement evaluation, environmental safe crisis management, judiciary and explanation responsibility with base.
