인도네시아 경쟁법: 실체규정과 절차규정의 분석

오준형 한국경쟁법학회 2022 競爭法硏究 Vol.45 No.-

Indonesia adopted the Competition Law in the late 1990s, the earliest among 10 ASEAN member States. The Competition Law contains three types of substantive regulations classified as prohibited agreements, prohibited acts, and dominant positions. The distinct characteristics of the Law is that judging horizontal agreement as rule of reason, judging abuse of dominant position as per se illegal, and reviewing mergers ex post. However, this also deserves respect as it is the result of an agreement that the representatives of the people to legislate and implement on the basis of the State's unique social, political, and economic experiences. Due the recent law amendment in 2020, it is is expected that the people’s interest on the Competition Law and ability of the judicial review will be increased because the amendment allows increased administrative surcharges, courts dedicated to review competition law cases as well as the extended judicial review period. However, the Competition Law, still, is on the way to catch up the global standard. For example, the Law has lack of investigation authority, extraterrestrial application provisions, leniency system, high burden of proof due to different examination criteria. ASEAN member States decided to introduce competition laws by 2015 and may of them have introduced or completely amended competition laws. Indonesia enacted the law in 1999 and has been in effect for over 20 years, with only one amendment to the law in 2020. This is also a step forward, but for more efficient and effective enforcement of the law, it is necessary to amend the law including the introduction of the leniency system and the authority to investigate. It is time to consider revising the Indonesian Competition Law to conform and converge with the global standard in consideration of regional block, activities of multinational corporations, competition chapter included in free trade agreements, and the formation of the ASEAN Economic Community.

Purpose: We investigated the effect of propiverine on cystometric parameters based on intraabdominal pressure (IAP) in awake rats in an overactive bladder (OAB) model induced by intravesical instillation of prostaglandin E2 (PGE2). Materials and Methods: Twenty-two female Sprague-Dawley rats were used. Polyethylene catheters were implanted into the bladder to record the intravesical pressure (IVP) and into the femoral artery to administer medication. A balloon-fitted catheter was positioned in the abdominal cavity to record the IAP. Awake cystometries were performed before and after intraarterial administration of propiverine 1 mg/kg (n=6), intravesical administration of 50μM PGE2 only (n=6), or intravesical PGE2 plus 1 mg/kg (n=4) or 3 mg/kg (n=6) of intraarterial propiverine. Cystometric pressure and volume parameters and variables related to detrusor overactivity (DO) were investigated. Results: Rats administered intravesical PGE2 showed increased pressure parameters and decreased volume parameters comparable to the DO model, which was effectively prevented by propiverine (1 or 3 mg/kg). Typical DO shown during the filling phase was decreased by intraarterial propiverine (3 mg/kg) injection. After propiverine (3 mg/kg) injection, IAP was increased at the time of micturition pressure with or without threshold pressure (p<0.05, p<0.01) depending on the dose administered. Conclusions: Propiverine improved pressure- and volume-related parameters in an OAB model. Furthermore, it also decreased the frequency of DO. However, higher concentrations of propiverine induced straining voiding.

This article presents the results which investigated elementary school students' and teachers' conceptions about the stars. Samples consisted of one hundred forty eight 5th-grade students, one hundred seventy four 6th-grade students, and thirty eight primary science teachers. Research method was paper-pencil test. Their responses to these questions revealed considerable apparent naive conceptions. and the study results proved that the items showing a high response rate of teachers' childhood concept also resulted in a high response rate of students' naive concept. A great of this apparent inconsistency could be explained by assuming that the students used, a naive core belief of the stars other than a target scientific concept of the stars. And, elementary school students and teachers often held a different naive core beliefs based on their other experiences rather than scientific theories. this paper was also discussed the core beliefs that elementary school students and teachers held to overcome these naive conceptions.

기반시설 침해사고 및 제어시스템 표준 동향

오준형(Jun Hyoung Oh),유영인(Young in You),이경호(Kyung Ho Lee) 한국정보보호학회 2017 情報保護學會誌 Vol.27 No.2

산업 제어 시스템은 사회 기반 시설이나 산업체의 설비를 감시하고 제어하는 시스템을 의미한다. 제어시스템의 효율적 관리를 위해 상용 기술과의 유사성이 증가함에 따라 기존 정보시스템들이 가지는 보안 취약점 또한 수반하게 되었다. 따라서 제어시스템에 대한 침해사고 또한 증가하게 되었으며, 우리나라의 경우 대표적으로 한수원 해킹 사건이 있다. 이렇듯 기반시설에 대한 침해 사고가 늘어나 산업제어시스템 보안에 대한 중요성이 강조되면서 국내외로 제어시스템 보안 표준이 제정 · 개정되고 있다. 특히, NERC CIP, ISA/IEC 62443, NIST 800 series 와 같은 표준은 매년 또는 격년마다 개정이 되는 등 매우 활발히 변화하는 사이버 위협에 적극적으로 대응하고 있다. 본 논문에서는 2006년부터 현재까지 발생한 주요 침해사고에 대해 알아보고, 동 기간 내 국제 표준 동향 및 국내 정보보호 관리체계를 조사한다. 이를 통해 국내 정보보호 관리체계의 구체적인 문제점을 파악하여 보다 나은 산업제어시스템의 안전성을 확보하고자 한다.

백인주,오준형,이경호 한국정보보호학회 2019 정보보호학회논문지 Vol.29 No.6

In this study, we analyzed the privacy policies of 50 Android applications that are on the top chart in EU members topresent the methods for enhancing transparency based on GDPR (General Data Protection Regulation). Based on theguidelines in relation to transparency stipulated in WP29, this study extracted factors of transparency in order to ensuretransparency of privacy data processing and carried out the verification procedures for each factor. The results revealed thatthe privacy policies provided in Google Play Store and applications need to be matched, the descriptions of the privacypolicies need to be written in clear and plain language for readers to understand easily. and that it is necessary to provideinformation quickly and improve the descriptions of information which the data controller discloses. The research findings ofthis study could be used as a preliminary data for proactive responses to the EU's GDPR by substantially complying withthe transparency of GDPR. 본 연구는 EU 회원국에서 상위권을 차지하는 안드로이드 애플리케이션 50개에 대한 개인정보처리방침을 분석하여, EU 일반 개인정보 보호법(GDPR)이 규정하는 투명성 확보방안을 제시하였다. WP29 작업반에서 제시한 투명성 관련 지침을 참고하여, 개인정보처리의 투명성 확보를 위한 요소를 도출하고, 각 요소에 대한 단계별 확인 절차를거쳤다. 그 결과, 현재 구글플레이스토어와 애플리케이션에서 각각 제공하고 있는 개인정보처리방침을 일원화하고, 개인정보처리방침을 설명하는 내용을 좀 더 이해하기 쉬운 표현으로 기술할 필요성이 제기되었다. 또한, 신속한 정보 제공 및 컨트롤러의 정보 기재 등이 개선될 필요가 있음이 제시되었다. 본 연구는 GDPR 5조 개인정보처리원칙 7가지중 하나인 투명성의 원칙에 기반을 두어 분석하였으며, 향후 실질적인 준수를 통해 EU의 GDPR에 선제적으로 대응할 수 있는 기초 자료로 활용될 수 있을 것이다.

Semantic object model has widely been recognized as an alternative data modeling approach to entity-relationship model for database system design. In this study, we have presented a semantic object model for intermediary type shopping mall consisting of multiple buyers and sellers. Essential processes and information with regard to the customer management, product management, price estimation, product order etc. have been considered for this study. Upon careful examination and analysis of them, a detailed semantic objects and attributes have been drawn and structured into semantic object diagrams. The final objects were converted into an entity-relationship diagram so that intuitive comparison could be made for relational database design. The results in this study may form a conceptual framework for both academic concerns and more complicated system applications.

재식별 시간에 기반한 k-익명성 프라이버시 모델에서의 k값에 대한 연구

김채운 ( Chaewoon Kim ),오준형 ( Junhyoung Oh ),이경호 ( Kyungho Lee ) (사)한국빅데이터학회 2020 한국빅데이터학회 학회지 Vol.5 No.2

빅데이터 활용 기술의 발전으로 데이터의 저장 및 공유가 늘어나면서 그에 따른 프라이버시 침해가 일어나게 되었다. 이 문제를 해결하기 위해 비식별 기술이 도입되었지만 비식별된 데이터에 대해서도 재식별이 가능하다는 것이 여러 차례 증명되었다. 재식별 가능성이 존재하기 때문에 완전히 안전할 수 없지만 그럼에도 불구하고 충분한 비식별처리가 이루어져야 하는데, 현재 법령이나 규제는 어느 정도로 비식별 처리를 해야 하는지 정량적으로 규정하고 있지 않다. 본 논문에서는 재식별 작업을 할 때 소요되는 시간을 고려하여 적절한 비식별 기준을 제시하려고 한다. 다양한 비식별 평가 모델 중에서 k-익명성 모델에 대해 집중적으로 연구하였으며 어느 정도의 k값이 적절한 지 판단하였다. 본 연구의 결과를 일반화시킬 수 있다면 각종 법률 및 규제에서 적절한 비식별 강도를 규정하는 데 사용할 수 있을 것이다. With the development of data technology, storing and sharing of data has increased, resulting in privacy invasion. Although de-identification technology has been introduced to solve this problem, it has been proved many times that identifying individuals using de-identified data is possible. Even if it cannot be completely safe, sufficient de-identification is necessary. But current laws and regulations do not quantitatively specify the degree of how much de-identification should be performed. In this paper, we propose an appropriate de-identification criterion considering the time required for re-identification. We focused on the case of using the k-anonymity model among various privacy models. We analyzed the time taken to re-identify data according to the change in the k value. We used a re-identification method based on linkability. As a result of the analysis, we determined which k value is appropriate. If the generalized model can be developed by results of this paper, the model can be used to define the appropriate level of de-identification in various laws and regulations.
