공정거래위원회는 지난 ''97년 12월 29일 1998년도에 적용될 시장지배적사업자로 128개 품목의 311개 사업자(순사업자:188개)를 지정하고 ''98년 1월 1일부터 시행에 들어갔다. ''98년도에는 ''97년도 지정품목 및 사업자 중 13개 품목, 50개 사업자가 신규로 지정된 반면 14개 품목, 45개 사업자가 지정제외되어 지난해인 ''97년도에 비해 시장지배적사업자는 5개 증가한 반면, 시장지배적품목은 1개가 감소하였다. 이번에 공정위가 시장지배적품목 및 사업자의 변동상황을 분석한 결과, ''98년도에 신규로 시장지배적품목으로 지정된 품목은 주로 매출액의 증가에 따른 자연증가가 많았던 반면, 지정제외품목은 대부분 시장집중도 완화에 기인하고 있는 것으로 나타났다. 또한 시장지배적품목으로 계속 지정된 품목의 경우에도 사업자간의 시장점유율 순위와 상위 3사가 변동한 품목이 $32.3\%$에 달한 것으로 나타나 전반적으로 시장경쟁이 촉진되고 있는 것으로 분석되었다. 시장지배적품목의 시장집중도의 경우에는 1사 지배품목의 수와 3사 지배품목 중 $90\%$ 이상의 고집중품목의 수가 감소한 것으로 나타났다. 공정위는 앞으로 시장지배적사업자에 대하여는 최근의 경제상황을 감안하여 물가와 민생안정에 역점을 두고 공정거래법을 집행해 나갈 계획으로 있다. 이를 위해 가격남용, 출고조절, 공동행위 등 물가안정을 저해하는 시장지배적사업자의 법위반행위에 대한 감시를 강화하고, 특히 휘발유, 맥주, 라면 등 물가와 서민생활에 큰 영향을 미치는 독과점품목에 대하여 철저히 감시할 계획이며, 독과점시장 구조개선시책의 일환으로 ''96년부터 추진하고 있는 26개 우선개선대상품목의 경쟁촉진방안을 적극적으로 추진할 계획으로 있다고 밝혔다.

Purpose: The purpose of this study was to investigate the effect of health literacy and unmet health care needs on health promotion behaviors among elderly people receiving visiting health care services at community health centers. Methods: The subjects of this study were 180 elderly people over 65 years old who were receiving health care services at public health center The subjects fully understood the purpose of this study and voluntarily agreed to participate. The collected data were analyzed by frequency, percentage, mean, standard deviation, independent t-test, one-way ANOVA, Scheffé test and Hierarchical Regression Analysis using the SPSS 23.0 program. Results: Hierarchical regression analysis was used to identify factors influencing health promotion behaviors of the subjects. The results were as follows: presence of occupation (β=.26, p<.001), social activity status (β=.26, p=.001), and health literacy (β=.16, p=.023). Conclusion: Therefore, in order to improve health promotion behaviors, it is necessary for visiting nurses to administer health education and programs by considering the level of health care understanding.

Recent massive data breaches or major security incidents show that threats posed by insiders have greatly increased over time. Especially, authorized insiders can cause more serious problems than external hackers can. Therefore there is a growing need to introduce a system that can monitor the insider threats in real time and prevent data breaches or security incidents in early-stage. In this paper, we propose a EITMS(Enterprise Insider-Threats Management System). EITMS detects the abnormal behaviors of authorized insiders based on the normal patterns made from their roles, duties and private activities. And, in order to prevent breaches and incidents in early-stage, a scoring system that can visualize the insider threats is also included.

본 연구의 목적은 아동 성폭력 상황 자체와 성폭력 가해자에 대한 간호사의 태도가 상황 판단에 미치는 영향을 규명하는데 초점을 둔다. 503명의 병원 간호사와 526명의 보건교사를 대상으로 vignette 디자인 설문조사를 실시하였다. 아동성폭력 상황 vignettes은 7가지의 특성 (성폭력 행위, 성폭력 빈도, 피해자의 연령, 피해자의 저항, 가해자의 연령, 가해자와 피해자의 교차성별, 가해자와 피해자와의 관계)을 조합하여 구성하였다. 1/4 factorial design의 결과로서 64개의 vignettes 이 도출되었으며 이 중 16개 vignettes을 무작위로 추출하여 그 vignettes에 나타난 각 성폭력 상황들의 심각정도를 표시하도록 하였다. 성폭력 가해자에 대한 문항들은 1) 가해자가 아동 성폭력을 하는 이유 2) 전형적인 성폭력 가해자3) 아동성폭력 가해자의 처벌방법에 관한 간호사의 태도를 묻는 것이었다. 자료분석은 Logistic Regression을 실시하였다. 연구결과에서 간호사들은 아동 성폭력 상황의 심각도를 판단할 때 주로 성폭력 상황에 의해 영향을 받고 아동 성폭력 가해자에 대한 개인적 태도는 거의 영향을 미치지 않는 것으로 나타났으며, 아동 성폭력 상황 특성 중 피해자의 저항, 성폭력 행위, 성폭력 빈도, 가해자의 연령, 가해자와 피해자의 교차성별 순으로 아동 성폭력상황의 심각도에 영향을 미치는 것으로 나타났다. 결론적으로, 간호사들은 아동 성폭력 상황에 직면하여 사례를 판단할 때 아동 성폭력 문제에 대한 개인의 태도에 영향을 받기보다는 사례 그 자체에 근거를 두고 판단하는 경향을 나타낸다. 본 연구 결과는 법적, 전문가적 의미에서 아동성폭력 신고자로서의 의무와 사례중재에 개입된 의료인으로서의 역할 수행에 긍정적인 면을 시사한다.

This paper described a character of the narrative in the computer game, especially targeting the newest edition 'SUPER MARIO(NDS, ie computer game in NITENDO). The series had gained popularity over 20 years with its attractions as changing graphics, developing computer technology. It also had been proved that a narrative was connected with a semiotic factor in the game. The analyzation of doer and space in the game that showed the narrative character explained the repetition and the modification, then deduced certain motif from it. This study was to certify that immersion and interesting in game were interacted with between a game factors and narratives, and it is meaningful for developing game story.

Overheated speculation areas which have high potential of becoming speculative are the target of many real estate policies. This paper proposes a model for spatial patterns of house price volatility and suggests a spatial pattern of overheated speculation areas. House prices are determined by economic behaviors of sellers and buyers who have rational or adaptive expectations. Spatial patterns of house price volatility are formed by tendencies of their economic behavior. If there is a majority of adaptive sellers and buyers in an area, it may appear as a "hotspot" by showing high volatility of house prices and simultaneous price increases. Overheated speculation areas are formed by adaptive sellers and buyers who want to realize maximum expectation profit, therefore these areas patterns are defined as hotspot patterns of price volatility.

This paper proposes normal behavior profiling methods for anomaly detection in IEC 61850 based substation network. Signature based security solutions, currently used primarily, are inadequate for APT attack using zero-day vulnerabilities. Recently, some researches about anomaly detection in control network are ongoing. However, there are no published result for IEC 61850 substation network. Our proposed methods includes 3-phase preprocessing for MMS/GOOSE packets and normal behavior profiling using one-class SVM algorithm. These approaches are beneficial to detect APT attacks on IEC 61850 substation network.

In this study, we revisit an empirical literature has found that neighborhood income inequality lowers people's likelihood of contributing public goods in terms of volunteering. We contribute to the literature by explicitly addressing the issues of larger and improper neighborhood choice with a census-type data and endogenous neighborhood location with some unique features of 2009 Social Survey Data by Statistics Korea. The results have confirmed that income heterogeneity lowers people's volunteering.

Recently the desired information has been recommended to many people in a number of ways using the smartphone. Though there are many applications for that purpose, but most applications does not consider the user's current situation. In order to automatically recommend the information considering the user's situation, it is necessary to predict the future behavior of the user from the records of the past behavior of the user. Therefore, in this paper, we propose a method that predicts the user's future behavior through association analysis based on the user's current behavior which is identified by applying the user's current situation data collected via a smartphone to the Bayesian network built from the user's life log. From the experiments and analysis for five students and five virtual workers, the usefulness of the proposed method is confirmed.

This paper analyzes the fundamental dynamic motion of a robotic arm and body mechanism on the platform of a mobile manipulation system. For the purpose, we reveal the dynamic coefficients of a robotic arm and body mechanism, and identify their dominant behaviors in an exemplar trajectory following simulation. We also discuss on their influence for the motion of the body, shoulder, and elbow joints. It is finally expected that this analysis is helpful for effective manipulation tasks by using mobile manipulation systems with an arm and body mechanism.
