김석중(Suk-Jung Kim),김재진(Jae-Jin Kim),최인석(In-Seok Choi),홍성도(Sungdo David Hong),정인원(In-Won Chung) 한국중독정신의학회 1997 중독정신의학 Vol.1 No.1
Chronic alcoholics show various degrees of dysfunction in abstraction, memory, perception, problem-solving ability, motor performance and so on. The evaluation of neurocognitive status is important to figure out the CNS effect of long-term heavy drinking and the prognosis of alcoholic patients. The present study was designed to assess cognitive deficits of alcoholics with recently developed computerized neurocognitive tests and to inspect the clinical applicability. We administered Standard Progressive Matrices, Cognitrone, Determination Unit, and Motor Performance Test Series in Vienna Test System(Schufried 1994), a computerized test battery, to twenty-two male hospitalized alcoholics who met DSM-III-R criteria for dependence and abuse and were abstinent for at least 6 weeks. Alcoholics tended to show less correct answers on Standard Progressive Matrices than controls, especially in difficult sets to solve, and displayed longer reaction time for correct answer on Cognitrone, less appropriate reactions and more missed reactions on Determination Unit, and poorer performances on Motor Performance Test Series. These results suggest that alcoholics with relatively long abstinence period, though somewhat improved, still manifest deficits of visuo-spatial intelligence, poor motor performance, and psychomotor clumsiness aggravated in stressful situations. Considering many advantages of computerized tests, the computerized neurocognitive tests may be clinically useful for assessing cognitive deficits in alcoholics under certain restriction.

주의력결핍 과잉행동장애 아동에서 혈중 납농도 수준과 문제행동 및 주의력과의 관계
김의정,김지훈,정유숙,홍성도,연규월 梨花女子大學校 醫科大學 醫科學硏究所 2002 EMJ (Ewha medical journal) Vol.25 No.1
연구목적 : ADHD의 원인은 아직 분명하게 밝혀지지 않았으며 그중 하나의 원인으로 제기되고 있는 것이 납과의 연관성이다. 최근에는 낮은 농도의 납 축적은 신경 행동학적인 손상과 직접적인 연관이 있다고 받아들여지고 있으며 주의력결핍 과잉행동장애의 다양한 치료적 접근은 적절한 평가와 원인에 대한 이해를 바탕으로 할 것이며 따라서 원인론에 대한 이러한 연구를 통하여 다양한 원인적 요소를 밝히고자 하는 노력은 매우 중요하다고 할 수 있다. 이에 본 연구에서는 혈중 납 농도와 주의력결핍 과잉행동장애 사이에 어떤 원인론적 연관성이 있을 것이라는 가설하에 1) 주의력 결핍 과잉 행동 장애 아동에서 혈중 납농도와 여러 영역의 문제행동 사이의 상관성 조사, 2) 혈중 납 농도와 CPT(Continuous Performance Test)간의 상관성 조사를 목적으로 한다. 연구방법 : 삼성서울병원 소아정신과에 내원한 환아로 소아정신과 전문의가 DSM-Ⅳ 진단 기준에 따라 주의력결핍 과잉행동장애로 진단한 62명의 환아를 대상으로 하였으며, 과거력이나 현 병력상 경련 질환이 있거나 대뇌손상의 경력이 있는 환아, 정신지체, 자폐아의 경우는 배제하였다. 대상아동의 평균 연령은 9.37±1.98세였다. 기초설문지를 통해 인구학적 특성을 조사하였고, 한국어판 부모, 교사용 아동문제 행동 평가 척도(Child Behavior Check-List), 단축형 Conners 평가 척도, WWPARS(Werry-Weiss-Peter Activity Rating Scale), HSQ(Home Situation Questionnaire), SSQ(School Situation Questionnaire)를 사용하여 가정과 학교에서의 문제행동의 정도와 상황을 평가하도록 하였다. 62명중 26명에서 주의력과 충동성의 정도를 파악하기 위하여 TOVA(The Test Of Variability of Attention)를 실시하였다. 모든 대상의 아동들의 전혈을 채혈하여 혈중 납농도를 측정하였다. 결과 : 1) 전체 62명 대상군의 평균 혈중 납농도는 3.39±1.32㎍/㎗이었다. 2)부모용 문제 행동 평가 척도중 사회적 위축척도와 혈중 납농도사이에는 0.33의 상관계수를 나타냈다(p<0.01). 3)TOVA의 측정요인중 omission error, commission error, variation과 혈중 납농도 사이에는 각각 0.34(p<0.1), 0.43(p<0.05), 0.34(p<0.1)의 상관계수를 나타냈다. 결론 : 혈중 납농도의 측정치는 부모용 문제행동 평가척도중 사회적 위축 척도와 연관을 보였으며, 주의력 및 충동성을 나타내는 TOVA 검사중의 omission error, commission error, variation 점수와도 연관성을 보였다. 이는 주의력결핍 과잉행동 장애 아동에서 혈중 납농도의 축적과 주의력 문제간에 어떤 연관성을 시사한다. Objective : It is now generally accepted that lead low doses may influence behavioral and attentional problems in children. The selection of a treatment approach depends on a proper assessment of the cause of the problem. This study was carried out to investigate the relationship between exposure to lead and behavioral and attentional problems in attention deficit hyperactivity disorder(ADHD). Methods : The participants were 62 boys, 6 to 12 years of age with ADHD. Children with probable causes of attentional or behavioral problems other than lead contamination were excluded from the study. Various aspects of behavioral problems were measured using questionnaires for parents and teachers. Attentional problems were measured with TOVA(The Test Of Variability of Attention). As an assessment of body lead burden, lead concentration in blood was measured. Results : Mean lead concentration in blood was 3.39 1.32㎍/㎗. Correlations between lead concentration in blood and the possible confounding factors were not significant. The results were same as that of lead concentration in attentional and behavioral problems. Lead concentration was significantly correlated with the scores of TOVA : omission error(r=0.34, p<0.1) ; commission error(r=0.43, p<0.05) ; and variation(r=0.34, p<0.1). Correlations between lead concentration and social withdrawal subscale of CBCL were significant(r=0.33, p<0.01). Conclusions : It appears that some link between low-level exposure to lead and performances exist.

네트워크 분석을 이용한 기술 표준화 방법론 연구: 사물인터넷 무선 통신 기술 계층을 중심으로
김경외,정성도,황준석,Kim, Keungoui,Jung, Sungdo,Hwang, Junseok 기술경영경제학회 2015 Journal of Technology Innovation Vol.23 No.3
기술 표준은 기술적 특성과 사양에 대한 일종의 사회적 합의로서 기술의 발달과 함께 모든 산업에 걸쳐 존속되어 왔으며 최근에는 정보통신 기술의 발달과 함께 기술의 상호호환성을 제공하고 시장의 우위를 선점할 수 있는 전략적인 요소로 각광받고 있다. 이에 기술 표준 연구(표준화 연구)는 기술 표준의 채택 과정과 이로 인한 경제적 효과를 분석하여 이론적 및 정책적 함의를 도출하는데 그 의의가 있다. 그러나 기존의 연구에서는 기술 고유의 가치와 상호호환성에 대한 고려가 부족하다는 점에서 기술 중심의 분석 결과를 도출하는데 있어 구조적 한계를 드러낸다. 본 연구는 기술 네트워크 분석을 통해 도출한 기술 차별화 정도와 기업별 기술 선호도 함수를 두 단계 게임 이론 분석 방법에 반영하여 새로운 기술 중심 표준 연구 방법론을 제공하는 것을 목적으로 하고 있다. 그 실증 사례로 사물인터넷의 무선 팬 기술을 선정하였으며, 본 연구 방법론을 통해 해당 시장의 기술 구조 및 표준 관련 함의를 도출하였다. Technology standard continues to exist as an social agreement throughout all industry. With development of Information and Communication, it is recently considered as a strategic factor for enhancing interoperability and increasing market dominance. Hence, technology standard research(standardization research) have a significance in analyzing the process of standard adoption and its economic effect and deriving theoretical and policy implications. However, as existing relative researches are lack in consideration on indigenous value of technology and its interoperability, there exists limitation in drawing the result of technology centered analysis. The goal of this study is to suggest new technology centered standard method by implying function of technology differentiation rate and technology preference that are deduced by technology network analysis into two stage game theory. As an example of empirical case, we selected wireless pan technology of Internet of Things, and derive its technological structure and implications related to standard.

이 연구의 목적은 기관지 천식아동의 기질특성을 알아보기 위한 것이다. 저자중 일인의 예비연구에 의하면 천식아동집단은 습진이나 알러지성 비염 등의 만성질환을 가진 아동집단이나 정상아동과는 다른 기질특성을 갖는다. 세 살에서 일곱 살 사이의 정상아동과 기관지 천식을 앓는 아동 85명의 어머니들에게 한국판"부모기질설문(Parental Temperamental Questionnaire)"을 완성하도록 하여 기질을 측정하였다. 기질의 9가지 범주 및 요인 A점수를 비교하기 위하여 비모수적 통계법을 사용하였으며, 아동들의 기질진단을 비교하기 위하여 Chi-square통계법을 사용하였다. 그 결과 천식을 앓는 여아집단은 정상 여아집단에 비해 적응성과 반응의 역치 범주에서 통계적으로 유의하게 낮았다. 또 정상아동집단의 11%가 기질진단적으로 양육곤란형인 반면 천식아동집단은 22%를 차지했다. 두 집단은 기질진단면에서도 통계적으로 유의한 차이를 보였다. 이와 같은 결과는 천식아동에 특징적인 기질양상이 있음을 시사한다. 기질양상의 조기발견은 부모들에게 천식아동의 건강한 발달을 이해하고 행동장애 고위험집단인 만성질환을 앓는 소아들에게 적절한 양육을 제공하는데 도움을 줄 것이다. The objective of this study was to determine temperamental characteristics of children with bronchial asthma. An earlier preliminary study(Kim SP, Ferrara A, Chess 5, 1980) results show that the asthmatic children, as a group, are significantly different from two other control groups(1. children with eczema, allergic rhinitis, or both without asthma : Ⅱ. normal healthy children in their temperamental profile). The parents of 85 Korean children with bronchial asthma, ages 3 to 7 years, completed the Korean version of Parental Temperamental Questionnaire developed by Thomas and Chess. The data collected were of ordinal type, ranked from 1 to 7 and the non-parametric Mann-whitney U Test was utilized. Any child with a suspected history or diagnosis of premature birth, organic brain syndrome, mental retardation, childhood psychosis, congenital physical anomaly, hereditary disease or any other medical or surgical conditions, other than asthma, requiring continuous physicians care was excluded from the study population. The results showed that asthmatic female children were characterized by lower adaptability and lower threshold of responsiveness. And 22% of asthmatic children were of the difficult type, compared to 11% of normal children. Both groups were statistically different in terms of temperamental constellation. The findings strongly suggest the existence of a distinct temperamental profile of asthmatic children. Early detection of the profile may be of great value for parents and child health care providers in understanding the asthmatic children's correct developmental needs and in determining appropriate parenting approaches for the chronically ill children at the risk of behavioral disorder.

Prioritizing Telecommunications Service Policies in South Korea: An Innovation System Approach
Kim, Hongbum,Kim, Eungdo,Lee, Daeho,Jung, Sungdo,Moon, Hyoungdon Korea Data Strategy Society 2015 Journal of information technology applications & m Vol.22 No.3
Although the telecommunications service industry has become a basic infrastructure component of the information and communication technology (ICT) industry, it is now losing its reputation as a cash cow due to achieving a saturation of service subscribers, especially in South Korea. With the exception of improving network speeds, network operators are experiencing difficulties in creating new innovations. Therefore, new innovations for the telecommunications service industry should be identified in conjunction with government policies for industry promotion. To examine the innovative capabilities of a specific industry, innovation system theories were used as a framework for research. However, existing innovation systems are limited with regard to explaining the openness of relationships and user participation which are general properties of the ICT industry. Moreover, as sources of innovative activity, additional values such as financial support and collaboration are more appropriate. This study presents a new innovation system based on innovation values. We analyze the telecommunications service industry and prioritize the importance of telecommunication policies within South Korea. An in-depth interview with experts based on the innovation system framework is conducted first. Next, innovation factors derived from the interview are applied within an analytic hierarchy process (AHP), leading to a prioritization of innovation factors for the telecommunications service industry.
