OSGi는 서비스 레지스트리를 통한 런타임 서비스 검색을 지원함으로써 서비스간의 인터랙션을 진작하는 대표적인 SOA기술이다. OSGi와 더불어 SOA의 선두 그룹을 형성하고 있는 웹 서비스 기술은 광역 인터넷에 위치한 네트워크 서비스들이 개방 인터페이스에 따라 상호 작용하여 새로운 부가 기능을 지원할 수 있도록 하는 토대를 제공하고 있다. 본 논문에서는 OSGi 프레임워크 환경에서 웹 서비스 조합 언어인 WS-BPEL을 이용하여 OSGi 서비스와 웹 서비스를 합성하여 복합 서비스 및 응용을 구성할 수 있도록 하는 새로운 기법을 제안한다. 이 결과 랜 환경을 주 대상으로 하는 OSGi 서비스와 광역 엔터프라이즈 환경의 웹 서비스가 소속 도메인 경계를 넘어 서비스 조합에 참여할 수 있게 됨으로써 단일 도메인 내 조합에서는 가능하지 않았던 응용 기능 지원이 가능해진다. OSGi enables services to be dynamically discovered through its service registry for fostering interactions among themselves, positioning itself as one of the most prominent SOA technologies. Web Services also provide a mature technical base of open business services being employed over the Internet and allow more value-added applications to be built up from component services. In this paper, we propose a new architecture, built on the concept of dynamic service binding, to support interbred service compositions of OSGi and Web Services. Web Services are imported into OSGi domains, and the compositions are described in WS-BPEL language. The support for crossbred compositions of OSGi services and Web Services opens up a new opportunity of a wider range of applications beyond their respective traditional target domains of home gateways in LAN environments and business applications in global Internet environments.

공감이 이직의도에 미치는 영향

고성훈(Sung-Hoon Ko),문태원(Tae-Won Moon) 한국인사조직학회 2012 인사조직연구 Vol.20 No.3

본 논문은 조직 내 공감(compassion)이 긍정적 정체성을 매개로 조직몰입에 어떻게 영향을 미치게 되며, 더 나아가 공감이 긍정적 정체성과 조직몰입의 두 개의 변수를 매개로 이직의도에 어떻게 영향을 미치게 되는지를 실증적으로 검증해 보고자 하였다. 또한 본 연구는 정서노동의 심층행동과 표면행동이 공감과 긍정적 정체성의 관계를 조절하는지 보고자 하였다. 국내 10개 기업 317명의 조직구성원들을 대상으로 실증적 연구를 실시한 결과, 공감은 긍정적 정체성과 통계적으로 유의한 정(+)의 관계가 있는 것으로 나타났다. 한편, 심층행동과 표면행동의 조절효과 검증에서는 심층행동이 클수록 공감과 긍정적 정체성의 정(+)의 관계를 강화시키는 반면에 표면행동은 공감과 긍정적 정체성의 정(+)의 관계에 아무런 영향을 미치지 않는 것으로 밝혀졌다. 마지막으로 긍정적 정체성은 공감과 조직몰입의 관계에서 완전매개 역할을 하는 것으로 밝혀졌으며, 공감은 긍정적 정체성과 조직몰입의 두 개의 변수를 통해 이직의도에 영향을 미쳐 공감과 이직의도 관계에 긍정적 정체성과 조직몰입의 부분매개 효과가 있는 것으로 나타났다. In this paper we construct a research model to explain how expressions of individual compassion in organizations affect workers’ intention to leave through the double mediation effect. This study also focuses on the effect demonstrations of compassion have on positive identity and organizational commitment. A theoretical framework conceptualizes how individual compassion shown in organizations generates positive identity, which subsequently impacts on intention to leave through organizational commitment. In addintion, Compassion expressed through deep acting has a moderating effect, and may create individual positive identity which leads to organizational commitment, while superficial compassion expressed through surface acting also has a moderating effect, but may increase the intention to leave the organization by decreasing organizational commitment. In other words, this paper demonstrates how deep acting and surface acting moderate the relationship between compassion and positive identity. Compassion, which has mainly been studied in the fields of religion and psychology, is here investigated in the context of business administration. Specifically, the relationship between individual compassion and positive identity within the organization is examined. Compassion is defined in this study as the consideration and care demonstrated about the pain that others experience within the organization. We analyze whether these compassionate behaviors affect organizational commitment and the intention to leave one's organization through the mediation effect of positive identity. The scales of compassion proposed by Lilius et al. (2008) are used for empirical analysis for the first time in a research setting. First, the means by which compassion affects positive identity is explored. Second, the moderating effect of emotional labor (deep acting and surface acting) on the relationship between compassion and positive identity is tested. Third, the mediation effect of positive identity on the relationship between compassion and organizational commitment is evaluated. Fourth, the double mediation effect of positive identity and organizational commitment on the relationship between compassion and intention to leave is investigated. In short, we argue that compassion through the mediation of positive identity not only strengthens organizational commitment, but also weakens the intention to leave through the double mediation effect of positive identity and organizational commitment. Furthermore, compassion will strengthen or weaken positive identity through the moderating effect of emotional labor (deep acting and surface acting). Our hypotheses can be summarized as follows: H1: Compassion will be positively associated with employees’ positive identity. H2a: Deep acting will positively moderate the relationship between compassion and positive identity. H2b: Surface acting will negatively moderate the relationship between compassion and positive identity. H3: Positive identity will mediate the relationship between compassion and employees’ organizational commitment. H4: Positive identity and organizational commitment will negatively double mediate employees’ intention to leave. Data was collected from ten organizations in Korea, representing four different industries: finance, general manufacturing, services industry, and networking industry. A total of 317 employees were surveyed (a 52.8% response rate from a pool of 600 employees). First, the results demonstrate that compassion had a significant impact on positive identity, supporting hypothesis H1. Second, to test the moderating effects of emotional labor (deep acting and surface acting), a series of hierarchical moderated regression analyses for each of the four independent variables. In the first step of each regression analysis, the control variables were entered. The second step added the independent variable [compassion].

1877년 張赫晉의 楸子島 공략 모의의 추이와 성격

고성훈(Ko Sung-hoon) 역사실학회 2006 역사와실학 Vol.30 No.-

Jang Hyug-jin, leading role of this incidence, was once exiled to Shinji Island(新智島) and subsequently moved to Heung Yang(興陽) because he was involved in Andong Uprising(安東變亂). And he attempted to rise against in concert with Lee Woo-su(李祐秀) there. Moreover he induced Choi Bong-ju(崔鳳周), who was involved in the 'Guwol Mountain Uprising(九月山變亂)' and later exiled to Chuja Island, to work for him as adviser. At the time Choi was influential, dubbed as 'King of Chu(楸王)' at the exile scene. Headquarters formed by Jang Hyug-jin, Lee Woo-su, Choi Bong-ju, and so on drew up an uprising to occupy the Chuja Island which had been controlled by Choi, and to attack Jejoo Island(濟州道) to be under control of a appropriate person from them as they would steal official building and the and wait for uprising on the ground at the proper time after arranging weapons. Jang Hyug-jin and his men started to recruit fellows while travelling through Kyungsang(慶尙) and Honam(湖南) provinces and to finance for the uprising. Especially, they exerted great efforts to brind around Lee Gi-gyp(李奇執), the ship owner of Jindo(珍島) Island, to secure ships necessary for the attack against Chuja Island. They actively got prepared, but failed due to whistle-blowing by Lee Gi Gyp. Despite the fact that they failed, this incidence was characterized by several spheres as follows. Firstly, Jang Hyug-jin and Choi Bong Ju, major roles of the incidence, had the same experiences to be engaged in insurrection which was a better factor to instigate fellows and facilitate other things. These continuous attempts showed that such uprisings had been the mainstream of popular movements at the time. Secondly, leading roles of the incidence like Jang Hyug Jin and so on took advantage of the ideology of the grass root from the 'Jeonggamnok(鄭鑑錄)'. As Jang let the rumor going around that Nam Joseon(南朝鮮) would invade them, it is logical that the study of the promulgation of 'Invasion from Nam Joseon' should be examined in the context of the theory of Jeonggamnok. Thirdly, the leading part of the incidence travelled through all parts of both Jeolla(全羅) and Kyungsang provinces to prepare for the uprising, which was marked by their space of activity. The discussed with fellows and contacted them in the nearby taverns in the vicinity of the market. It is quite noteworthy that the intriguing place for the rebellion like this incidence was easily spotted. Lastly, such leading roles as Jang Hyug-jin, Choi Bong-ju and so on did not suggested the definite details such as its purpose, future plans after success. Meanwhile, this has various features of then uprisings. And judging from the period and time, the uprisings of Guwolsan(九月山, 1853), Kwangyang(光陽, 1869), Lee Phil-jae(李弼濟, 1870), etc. was transcended to the Donghak Peasant War(東學農民戰爭).

33권6호 영문부록 : 흰쥐의 적출 심장에서 허헐처리후 Ketanine 의 양성 변력성 효과의 기전

서 론: Ketamine은 여러 실험동물의 적출 심장에서 양성 변력성 작용을 보인다. 이러한 작용의 기전은 K+ 이온통로 억제에 의한 세포막 전위의 탈분극에 의해, 전압 민감성 Ca2+ 이온통로를 경유한 Ca2+ 이온의 세포내 증가로 여겨지고 있다. 본 연구에서는 K+ 이온통로의 일종으로 심장에서 허혈이나 저산소증시 활성화되는 ATP-민감성 K+ (ATP-sensitive K+, KATP) 이온통로와 심근허혈시 ketamine의 양성 변력성 작용의 상호 관계를 알아보고자 하였다. 방 법: 흰쥐 적출심장을 Langendorff 장치에 현수한 후 Krebs-Henseleit (KH)용액을 55 mmHg의 압력으로 관상동맥으로 관류시키면서 관류량을 측정하여 이때 관류량의 절반을 일정한 속도로 관류시켜 심근의 허혈을 유발하였다. 수축력의 측정은 좌심실의 압력 변화를 측정하였으며, 세포내 Ca2+ 농도의 변화는 단일 심실근 세포를 분리후 Ca2+과 결합하는 형광색소인 fura-2를 이용하여 측정하였다. 결 과: Ketamine은 수축력의 지표인 좌심실압을 용량 의존성으로 증가 시켰으며, 이는 propranolol (10-6 M)의 영향을 받지 않았다. 100 M의 ketamine은 좌심실압을 대조치에 비해 31.2 4.6% 증가 시켰으나, KATP 이온통로의 길항제인 glibenclamide (10-5 M) 존재하에서는 10.5 3.3%만을 증가 시켰다. 또한, K+ 이온통로 활성제인 pinacidil (3x10-5 M)은 좌심실압을 34.7 4.9% 감소시켰으나, ketamine 존재하에서는 단지 21.2 4.4%만을 감소시켰다. 고농도의 ketamine은 세포내 Ca2+ 농도를 증가시켰다. 결 론: Ketamine은 좌심실압과 세포내 Ca2+ 농도를 용량의존성으로 증가시켰다. 이러한 결과는 흰쥐의 적출심장에서 허혈시 ketamine이 양성 변력성 작용을 나타내며, 이는 KATP 이온통로의 억제가 부분적으로 관여함을 시사한다.

Since the wall thickness can be up to 6" or greater, welds must be made in many layers, each layer containing several passes. However, the welding time for the conventional welding processes such as SAW(Submerged Arc Welding) and FCAW(Flux Cored Arc Welding) can be required many hours. The aim of this paper is to develop a high speed welding system with multi-torch and laser vision sensor for increasing the production speed on the line and to remove the need for the operator so that the system can run automatically for the complete multi-torch multi-layer weld. It was shown that the developed laser vision sensor and analysis of arc blow for multi-torch were effective for multi-pass seam tracking and stable arc. A new automated multi-torch welding systems for thick wall applications has been proved in several production lines.

공유된 긍정 정서(Shared Positive Affect)의 기제, 선행요인과 결과에 대한 고찰 및 긍정 조직학(Positive Organizational Scholarship)에의 적용

이승윤(Seung-Yoon Rhee),고성훈(Sung-Hoon Ko) 한국인사조직학회 2017 인사조직연구 Vol.25 No.2

지난 25년여 간 축적된 공유된 정서 연구를 통해 정서의 공유를 활발하게 하는 선행 요인들과 공유된 정서의 결과, 이러한 결과를 설명하는 다양한 기제에 대한 깊이 있는 이해가 가능해졌다. 이에 본 연구는 개인 간, 집단 내, 그리고 조직 내에서 일어나는 긍정 정서의 공유 현상에 대한 연구를 개관하는 데 첫 번째 목적이 있다. 긍정 정서의 공유 현상을 촉진하는 선행요인들을 개인 수준에서는 정서적 성향 및 집단에 대한 태도, 개인 간 관계 수준에서는 리더의 정서표현이 부하에게 전이되는 현상에 초점을 맞추었다. 집단 수준의 선행요인으로 집단 내 사회적 구조, 정체성, 집단 감성지능의 역할을, 조직 수준에서는 정서규범 및 정서적 문화가 긍정 정서의 공유에 미치는 영향을 중심으로 문헌을 고찰하였다. 나아가 공유된 긍정 정서가 놀이와 같은 상호작용(playful interaction)을 촉진하여 인지적, 사회적 즉흥성을 활성화하고 장기적으로 심리적, 사회적 자원을 구축함으로써 집단 내 다양한 사회적 프로세스와 성과에 영향을 미치는 과정을 살펴보았다. 공유된 긍정 정서는 일반적으로 협력과 창의성 증진 등의 긍정적인 결과를 가져오지만, 의사결정의 질의 저하나 집단사고 등 부정적인 결과도 발생 가능한 것으로 나타난다. 특히 본 연구는 공유된 긍정 정서에 초점을 둠으로써, 조직 내 긍정적인 요소들을 개발하고 촉진하여 구성원들의 번영감과 성장을 도모하고 평균 이상의 탁월한 조직으로 나아가는 방향을 제시하는 긍정 조직학과의 관계를 조명하고 향후 연구방향을 제안하는데두 번째 목적이 있다. 특히 공유된 긍정 정서가 직장 내 공감을 불러일으키고 활력 관계를 구축하며 원활한 관계적 조정과 협력적 직무 재창조 활동을 촉진하는 역할에 초점을 맞추었다. 끝으로 공유된 긍정 정서 분야가 향후 탐색해야 할 과제를 구성원 간 상호작용, 정서적 다양성, 공유된 부정정서에 대한 연구의 필요성에 중점을 두고 논의하였다. 앞으로 공유된 긍정 정서에 대한 연구가 더욱 활성화되고, 긍정 조직학을 비롯한 다양한 연구 분야로 확대 적용되기를 기대한다. A growing research interest centers on the role that shared affect plays in group life. Over the past 25 years, the body of research on shared affect has developed significantly and has enhanced our understanding of its mechanisms, antecedents, and outcomes. This article firstly aims to review and synthesize research on shared positive affect at dyadic, group, and organizational levels. We begin by defining shared affect and examining four major types of antecedents: (a) affectivity and attitude toward group at individual level; (b) influence of leader affect on followers at dyadic level; (c) social structure, group identity and team emotional intelligence at group level; and (d) emotional norm or affective culture at organizational level. We then suggest how shared positive affect can foster cognitive and social spontaneity through playful interactions, which, when accumulated over time, tend to build social and psychological resources. Such interactions and resources enable individuals, groups, and organizations to exhibit positive outcomes in general, including increased cooperation and creativity. However, negative outcomes are possible as well, such as decreased decision quality or group think. Our focus on shared positive affect, in particular, opens up the possibility of fostering positivity in workgroups through such fundamental mechanisms as positive emotions and feelings shared between individuals, within teams, and within organizations. Hence, the second goal of this article is to shed light on the possibility of linking research on shared positive affect and the domain of positive organizational scholarship, and to propose future research directions. Shared positive affect has the potential to help individuals, groups, and organizations to grow, flourish, and excel through relationships and practices of positive nature, including compassion at work, energizing relationships, relational coordination, and collaborative job crafting. We hope that the theoretical framework outlined in this research will facilitate further exploration of the role shared positive affect plays in the domain of positive organizational scholarship.

As super connection society has been emerging, digital technology is equally while providing a number of convenience to improve the quality of life is also serious abuses. Hacking led to cyber crime in the form of technical and highly developed, it appears as an open cyber attacks on government agencies and international organizations. Their behavior has been changing to destructive patterns in the form that interfere with infrastructure operation and remove the key information. This situation is to have a direct impact to the Third World countries, including developed countries, national leaders can raise awareness about cyber security as the country``s survival levels from ‘collateral threat’ level. More than 50 countries in the world, which are believed to be operating a cyber command or such a similar cyber dedicated unit. Countries that possess nuclear weapons that is the United States, China, Russia, Britain, France, and the countries which might be have or develop nuclear weapons in the country i.e. India, Israel, Iran and North Korea, all of these countries, and many other countries also raise the heat to enhance cyber warfare capabilities. As you sum the institutions that exist in non-military forms, the majority of the country is becoming equipped with the power to perform cyber warfare. Cyber warfare in the Middle East between Israel and Palestine, the US and China cyber conflict, fighting back for a cyber attack on Iran``s nuclear facilities, cyber provocation towards South Korea from North Korea, which show that cyber warfare is going on around the world. Cyber-terrorism was caused by a particular minority so far, now, it is prevalent as national scale project which has the scale of cyber warfare. In this paper, we try to look at the response capabilities of major nation and deployment aspects of this tendency of cyber warfare. Until now the border was the basis of national security. In the cyber world, however, cyber warfighting systems, human resources and technology to support them in that country, and digital leadership are a borderline.

Dual Fuel 엔진의 노킹 검지 알고리즘에 관한 민감도 연구

최항섭(Hang Soeb Choe),고성훈(Sung Hoon Ko),우상표(Sang Pyo Woo),김용백(Yong Baek Kim) 대한기계학회 2019 대한기계학회 춘추학술대회 Vol.2019 No.11

In the gas fuel operation mode of the Dual Fuel engine, knocking may occur in response to changes in the surrounding environment or rapid dynamic behavior. Because these knocks can cause engine damage, effective knock detection and control techniques are essential to improving engine power and efficiency. Generally, if knocking is not detected and controlled initially, its strength tends to increase gradually, so development of an algorithm suitable for engine characteristics that can be accurately detected at the beginning of knocking is required. In this study, we analyzed the knocking frequency characteristics of a medium-sized engine using vibration and pressure sensor signals. Based on this, the optimum knocking detection algorithm with excellent knocking detection sensitivity was designed and evaluated.

임상연구 : 전신마취 중 심전도의 교정 QT 간격에 대한 Ondansetron의 영향

김종익 ( Jong Ik Kim ),이상귀 ( Sang Kyi Lee ),손지선 ( Ji Seon Son ),고성훈 ( Seong Hoon Ko ) 대한마취과학회 2007 Korean Journal of Anesthesiology Vol.53 No.6

Background: Prolongation of the corrected QT interval (QTc) has a potential risk of inducing life-threatening cardiac dysrhythmia. Although 5-HT3 antagonists are useful antiemetics, several cases of cardiac dysrhythmia after administration of 5-HT3 antagonists have been reported. Therefore, this study was conducted to evaluate the changes in QTc interval that occur after administration of a clinical dose of ondansetron during general anesthesia. Methods: Seventy-five patients, who underwent elective surgery under standardized general anesthesia were evaluated. After anesthetic induction, the patients were given either normal saline, 2 mg or 4 mg of iv ondansetron. The QTc on the electrocardiogram was measured immediately prior to administration of the treatment drug and then every minute after injection of the study drug for 10 minutes, 12 and 15 minutes. Results: There were no differences observed in the baseline QTc of the different treatment groups. In addition, there were no significant changes in the QTc interval of the control group, however, the QTc interval was prolonged significantly in both the ondansetron 2 mg and 4 mg groups. Further, ΔQTc (the difference in QTc interval from the baseline value) was significantly prolonged in the ondansetron 2 mg and 4 mg groups when compared with the control group. There were no differences in the number of patients who showed abnormal QTc and there were no incidences of dysrhythmia in any of the three groups. Conclusions: Ondansetron administration for emesis prophylaxis during general anesthesia was associated with statistically significant prolongation of the QTc interval. The authors recommend that caution be used when ondansetron is administered to prevent and/or treat postoperative nausea and vomiting, particularly in patients who have a prolonged QTc interval.
