한국에서 사물인터넷과 관련한 빅데이터 보호제도의 현재와 그 방향 ― 사물인터넷의 특성과 부정경쟁방지 및 영업비밀보호에 관한 법률에 의한 보호의 충분성에 중점을 두고

빅데이터의 보호는 사물인터넷이 활성화와 함께 일반인의 관심을 모으고 있는 영역이다. 자연스럽게 기존 보호제도의 문제점을 지적하면서 새로운 지식재산권에 의한 보호주장들이 분출되고 있다. 하지만 사물인터넷 관련 빅데이터는 다른 빅데이터와는 사물인터넷 기술의 특성에 따라 보안조치에 의한 비공지성, 추적가능성에 바탕을 둔 사용자의 개인정보와의 불가분성 등 여러 가지 다른 특징을 가지고 있고, 이러한 특성을 무시한 새로운 지식재산권에 의한 보호는 그 소유권 귀속과 같이 해결하기 어려운 여러 가지 법률적 쟁점을 야기할 뿐이다. 반면, 비공지성을 갖춘 정보를 보호하는 한국의 부정경쟁방지 및 영업비밀보호에 관한 법률과 그 보호범위에 관한 법원의 해석은 다른 국가와 다르게 영업비밀, 영업상 주요자산, 제2조 제1호 ㈘목의 부정경쟁행위라는 틀을 통해 이를 다양하게 분류해 보호하고 있다. 또한 그 정보의 독점력이 가진 가치에 따라 다양한 범위의 형사적 제재 및 민사적 보호를 폭넓게 제공하고 있다. 이에 따라 사물인터넷 관련 빅데이터 중 그 가치를 달리하는 사전처리를 거친 데이터세트, 비식별화 조치를 거친 데이터세트, 원시데이터 상태의 빅데이터에 관해서도 충분한 보호를 제공하며 사물인터넷 관련 빅데이터 거래에 있어 중요한 장애물인 개인정보 보호에 관련하여 재식별을 막아 빅데이터 거래 활성화를 가능하게 하는 장점도 가지고 있다. Protection of Big Data draws attention of general public beyond related experts as Internet of Things(hereafter ‘IoT’) spreads. Naturally, discussions of introduction of new intellectual property protection measures that points out the fault of existing protections are erupting. However, IoT related Big Data has many distinct features from other Big Data including non-publicity originated from security measures, inseparability of user’s personal information by traceability. Accordingly, new protection measures by intellectual property to IoT related Big Data bring out unsolvable numerous legal issues like attribution of ownership. The Unfair Competition Prevention and Trade Secret Protection Act and court’s interpretation(hereafter ‘the Act’) protects non-public information in Korea by utilizing frames of trade secret, major assets in business and unfair competitory acts by section 2.1(Ka) unlike other countries. The Act provides various and wide range of criminal sanctions and civil protection measures according to the value of the information by monopoly powers. It sufficiently protects pre-processed dataset, de-identified dataset, Big Data in raw data status among IoT related Big Data and has the advantage of helping active trading of Big Data by discouraging re-identification of personal information which is one of main barriers to trading of IoT related Big Data.

Objective: Cyber addiction, which is more vulnerable in adolescents, is defined as the excessive use of computers and the Internet that causes serious psychological, social, and physical problems. In this study, we investigated the resting-state functional connectivity (rsFC) in adolescents with cyber addiction. Methods: We collected and analyzed resting-state functional neuroimaging data of 20 patients with cyber addiction, aged 13−18 years, and 27 healthy controls. Based on previous studies, the seed regions included the dorsolateral prefrontal cortex, medial orbitofrontal cortex, lateral orbitofrontal cortex, dorsal anterior cingulate cortex, insula, hippocampus, amygdala, nucleus accumbens, and the ventral tegmental area. Seed-to-voxel analyses were performed to investigate the differences between patients and healthy controls. A correlation analysis between rsFC and cyber addiction severity was also performed. Results: Patients with cyber addiction showed the following characteristics: increased positive rsFC between the left insular−right middle temporal gyrus; increased positive rsFC between the right hippocampus−right precentral gyrus; increased positive rsFC between the right amygdala−right precentral gyrus and right parietal operculum cortex; increased negative rsFC between the left nucleus accumbens−right cerebellum crus II and right cerebellum VI. Conclusion: Adolescents with cyber addiction show altered functional connectivity during the resting state. The findings of this study may help us better understand the neuropathology of cyber addiction in adolescents.

Minsoo Park,Kazuto Okayasu,Hiroshi Fukutomi,Kwonhoo Kim 대한금속·재료학회 2016 METALS AND MATERIALS International Vol.22 No.6

The formation behavior of basal texture during high temperature deformation of AZ91 magnesium alloysin single phase was investigated by plane strain compression deformation. Three kinds of specimens withdifferent initial textures were machined out from a rolled plate having a <0001> texture. The plane straincompression tests were conducted at a temperature of 723 K and a strain of 5.0 × 10-2s-1, with a strain rangebetween -0.4 and -1.0. After deformation, the specimens were immediately quenched in oil. Before deformation,specimen A, {0001} was distributed at the center of pole figure; specimen B shows {0001} wasdistributed at TD direction; and specimen C, {0001} was distributed at RD direction. Texture evaluationwas conducted by Schulz reflection method using nickel-filtered Cu Kα radiation and EBSD. It was foundthat the main component of texture and the accumulation of pole density vary depending on the deformationcondition and the initial texture in all types of specimens. The crystal orientation components in this studywere formed by continuous deformation and discontinuous deformation, also when (0001) existed beforedeformation, an extremely sharp (0001) (compression plane) texture was formed.

False Normalization of Ankle Brachial Index: A Case of Lower Extremity Peripheral Arterial Disease with Normal Ankle-Brachial Index

Minsoo Sung,Yo Han Jung,Kyung-Yul Lee 대한신경초음파학회 2023 대한신경초음파학회지 (JNN) Vol.15 No.1

Screening for lower extremity peripheral arterial disease (PAD) is essential in assessing a patient’s risk of cerebrovascular disorders. The ankle-brachial index (ABI) is widely used as a screening tool for PAD, but it can produce falsely normalized results due to factors like artery calcification and collateral vessels. We report a patient with normal ABI but confirmed lower extremity PAD through ultrasound and computed tomography (CT). This case shows the limitation of ABI for PAD diagnosis. Additional tests, such as CT or ultrasound, should be considered when PAD is suspected, even if the ABI is normal.

Reconsidering the Determinants of Life Satisfaction among the Elderly in South Korea

Minsoo Jung,Chung Gun Lee,Byong‐,Hee Cho 한국보건사회학회 2010 보건과 사회과학 Vol.0 No.28

우리나라는 2000년 이후 고령화가 급속히 진전되고 있다. 많은 노인들이 가족들과의 접촉이 없고, 의료 보호에 취약하며, 사회경제적 지위가 낮음에도 불구하고 노인 인구의 삶의 만족도에 관심을 가지지 못했다. 이 논문의 목적은 노년 인구에서 삶의 만족도와 관련된 다양한 요인들을 파악하여 노년의 삶에 대한 이해의 폭을 넓히는 것이다. 본 연구에 사용된 자료는 2006년 고령화 패널 1차년도 자료이다. 이 자료에서 65세 이상 노인 인구 4,155명을 대상으로 연구를 진행하였다. 독립변수는 기존의 연구들에서 삶의 만족도에 영향을 미치는 것으로 알려진 7개 영역의 20개 변수이며, 분석방법으로는 위계적 회귀분석을 사용하였다. 관심변수는 사회인구학적 변수, 건강 행태 변수, 의료 보호 변수, 사회적 지지 변수 등이며 성별로 나누어 분석을 실시하였다. 남성의 경우 삶의 만족도를 결정하는 가장 큰 요인은 경제적 수준의 양호함 정도였고, 그 외에 자녀들과의 관계, 본인의 건강상태, 자녀들과의 접촉 빈도, 자녀들의 사회경제적 지위, 민간보험 여부가 삶의 만족도와 통계적으로 유의미한 연관성을 보였다. 반면에 여성의 경우는 삶의 만족도를 결정하는 가장 큰 요인은 자녀들과의 관계에 대한 만족도였고, 그 외에 경제적 수준, 본인의 건강상태, 인지기능 점수, 우울증 정도가 삶의 만족도와 통계적으로 유의미한 연관성을 보였다. 고령화는 더 이상 먼 미래의 이야기가 아니다. 그러므로 증가하는 노년 인구를 적극적으로 관리하는 정책을 수립하고 노년기에 대한 새로운 자화상을 만들어야 한다. 삶의 만족도에 대한 연구는 이를 위해 필요하다. 노인들의 삶의 만족도는 개인보다는 가족의 문제이고, 더 나아가서는 사회적 문제의 성격을 가진다. 특히, 성별에 따라 노인들의 삶의 만족도에 영향을 미치는 결정요인이 다르다는 점을 고려한 정책 마련이 요청된다. Older adults with chronic diseases have the lower life satisfaction and years of life remaining in the status of an aging society, South Korea since 2000. They are placed in the lack of family contacts and poorer health insurances, and economic disadvantaged condition as well. The purpose of this study is to understand senescence through colorful determinants concerning the life satisfaction of the elderly. Data were obtained from 2006 Korean Longitudinal Study of Ageing. Sample of this study consists of 3,960 Koreans aged 65 years or older have at least one chronic disease. We will measure effects of family types and health insurance conditions on life satisfaction controlling for respondent s socioeconomic factors. Lower life satisfaction might be significantly associated with small family scale and lower social contacts. In case children and spouse don t co?reside with them particularly, highly significant association with chronic disease prevalence rate and older adults have no family support would be demonstrated. The difference was found in life satisfaction as a level of health insurance with controlling for utilization of medical facilities. Aging is the common social issue of most countries in East Asia. Consequently, it is required that care givers are divided into personal or family burden and social burden. Life satisfaction and life expectancy related to these two factors of an advanced age population with chronic diseases could be the evidence of policy intervention approach. Lack of social support and medical accessibility increases fragility and disturbs well?being in senescence.

Robust Position Control of One DOF Mechanical Systems Using Dual PIOs Without Velocity Measurement

Minsoo Han,Cho Won Lee,Joo-Hyoung Yook,Young Ik Son 대한전기학회 2017 Journal of Electrical Engineering & Technology Vol.12 No.1

This paper presents a robust position controller for a one degree-of-freedom (DOF) mechanical system using only position measurement. In order to alleviate the performance degradation owing to various uncertainties, a two-stage design method is studied by employing a proportional integral observer (PIO). In the first stage, a baseline backstepping controller is designed for a nominal system without accounting for uncertainties. The PIO is developed for estimating both the velocity information for the backstepping controller and an equivalent input disturbance for a feedforward compensation using the estimated uncertainty. It is shown that the estimation errors with the proposed PIO can be made arbitrarily small in a finite time. If the system suffers from undesirable actuator nonlinearities, however, it might be necessary to estimate the velocity and the disturbance with different rates of convergence. The proposed method combines the predesigned backstepping controller and dual PIOs to reduce mechanical vibrations as well as steady-state errors. The performance of the proposed method is tested through comparative computer simulations and experiments using a laboratory prototype.

Speaker Adaptation Using i-Vector Based Clustering

( Minsoo Kim ),( Gil-jin Jang ),( Ji-hwan Kim ),( Minho Lee ) 한국인터넷정보학회 2020 KSII Transactions on Internet and Information Syst Vol.14 No.7

We propose a novel speaker adaptation method using acoustic model clustering. The similarity of different speakers is defined by the cosine distance between their i-vectors (intermediate vectors), and various efficient clustering algorithms are applied to obtain a number of speaker subsets with different characteristics. The speaker-independent model is then retrained with the training data of the individual speaker subsets grouped by the clustering results, and an unknown speech is recognized by the retrained model of the closest cluster. The proposed method is applied to a large-scale speech recognition system implemented by a hybrid hidden Markov model and deep neural network framework. An experiment was conducted to evaluate the word error rates using Resource Management database. When the proposed speaker adaptation method using i-vector based clustering was applied, the performance, as compared to that of the conventional speaker-independent speech recognition model, was improved relatively by as much as 12.2% for the conventional fully neural network, and by as much as 10.5% for the bidirectional long short-term memory.
