본 연구에서는 정부의 포괄적 네거티브 규제 정책에 의해 선정된 부산 블록체인 규제자유특구의 활성화를 위한 정책방안을 제안하고자 한다. 우리나라는 유럽이나 미국과는 달리 포지티브 규제 기반으로, 활성화가 아닌, 억제를 목적으로 하므로 경제·산업 분야에서 지속적인 개혁 대상으로 취급된다. 문재인 정부는 이러한 포지티브 규제의 문제점을 해소하기 위한 획기적인 규제 혁신 정책으로 '포괄적 네거티브 규제'로의 전환을 제시하였다. 이에 대한 실행 방안으로 규제자유특구법에 기초한 신산업 육성을 위한 1단계 규제자유특구 7곳을 우선 선정하였다. 부산시는 '블록체인 규제자유특구'로 최종 선정되었으며, 블록체인을 바탕으로 침체된 지역경제를 활성화할 기회를 확보하였다. 본 연구는 부산 블록체인 규제자유특구의 활성화를 위한 정책 연구로, 규제자유특구에서 사업화할 수 있는 부산 특화 블록체인 서비스 발굴과 함께 산업 생태계 조성을 위한 방안을 제안하고자 하였다.

This study examined the negative cognitive regulation's mediating role between affectionate relationship with children's mother and loneliness. The subjects were 491 5th and 6th grade school children in Seoul and $Ky\breve{o}nggi$. Data were analyzed by Pearson's correlation and regression. Results showed that affectionate relationship with children's mother was positively related to negative cognitive regulation. Affectionate relationship with children's mother and negative cognitive regulation was negatively related to loneliness. The principal finding was that negative cognitive regulation had mediating role between affectionate relationship with children's mother and loneliness in boys. But negative cognitive regulation didn't have mediating role between affectionate relationship with children's mother and loneliness in girls.

Natural killer (NK) cells play key roles in innate and adaptive immune defenses. NK cell responses are mediated by two major mechanisms: the direct cytolysis of target cells, and immune regulation by production of various cytokines. Many previous reports show that the complex NK cell activation process requires de novo gene expression regulated at both transcriptional and post-transcriptional levels. Specialized un-translated regions (UTR) of mRNAs are the main mechanisms of post-transcriptional regulation. Analysis of posttranscriptional regulation is needed to clearly understand NK cell biology and, furthermore, harness the power of NK cells for therapeutic aims. This review summarizes the current understanding of mRNA metabolism during NK cell activation, focusing primarily on post-transcriptional regulation.

In this study of the influence of marital conflict and of children's temperament and emotion regulation on problem behavior, 194 mothers of 3- to 5-year-old children responded to the O'Leary- Poter Scale(1980), the Emotionality, Activity and Shyness scale(Buss & Plomin, 1984) and the Emotion Regulation Checklist(Shields & Cicchetti, 1997); teachers rated children's behavior on the Problem Behavior Questionnaire(Behar & Stringfield, 1974). Data were analyzed by independent t-tests, correlations, and multiple regressions. Results demonstrated that shyness, activity, and emotion regulation had direct effects on hostile-aggressive behaviors. Shy temperament had a direct effect on fearful-anxious behavior. Both marital conflict and temperament influenced hostile-aggressive behaviors indirectly through emotion regulation, implying a crucial role of emotion regulation in preschoolers' social development.

This study investigated the influence of audience type (mother or close friend) age, and gender on children's goals and strategies for emotional regulation in angry and in sad situations. Hypothetical vignette methodology was used with 314 children in grades 5 and 7. In angry situations, all boys and all 5th grade children regulated anger more with instrumental motives while 7th grade girls showed more prosocial motives. Children showed more prosocial and rule oriented motives with peers and relational motives with mothers. In angry situations, children used aggression regulation strategies more toward peers and activity regulation strategies more toward mothers. Children's age and sex explained sadness regulation motives better than audience type with peers, but children used more activity regulation strategies with mothers in sad situations. When sad, fifth graders used more verbal and facial expression strategies than 7th graders while boys used more activity regulation strategies than girls.

Genetic networks are a key to unraveling dynamic properties of biological processes and regulation of genes plays an essential role in dynamic behavior of the genetic networks. A popular characterization of regulation of the gene is a kinetic model. However, many kinetic parameters in the genetic regulation have not been available. To overcome this difficulty, in this report, state-space approach to modeling gene regulation is presented. Second-order systems are used to characterize gene regulation. Interpretation of coefficients in the second order systems as resistance, capacitance and inductance is studied. The mathematical methods for transient response analysis of gene regulation to external perturbation are investigated. Criterion for classifying gene into three categories: underdamped, overdamped and critical damped is discussed. The proposed models are applied to yeast cell cycle gene expression data.

According to the Article 4(Confirmity Assessment)of the Electrotechnical Regulation, Confirmity Assessment for the Electrotechnical Regulation decides confirmity of Electrotechnical Regulation; whether to satisfy performances and requirements(determined from Electrotechnical Regulation). It evaluates technical requirements, new technology and standards. However, it does not evaluate technical content stated from Electrotechnical Regulation & Conformity Criteria. From Confirmity Assessment, the technology will be decided whether to fulfill performances and technical requirements. Which is predetermined by contents related to Electrotechnical Regulation. Test standards and test conditions will be overlooked to determine its performances and technical requirements for safety. This paper will show that, studies have been done to determine the guideline for Confirmity Assessment, which is evaluated from performances and technical requirements associated with Confirmity Assessment of electrical installation for new technology of wireless power transfer.

A conventional LDO(Low Dropout Regulator) uses one OPAMP and one signal path. This means that OPAMP's DC Gain and Bandwidth can't optimize simultaneously within usable power. This also appears that regulation property and settling time of LDO can't improve at the same time. Based on this idea, a proposed LDO uses two OPAMP and has two signal path. To improve regulation property, OPAMP where is used in the path which qualities DC gain on a large scale, bandwidth designed narrowly. To improve settling time, OPAMP where is used in the path which qualities DC gain small, bandwidth designed widely. A designed LDO used 0.5um 1P2M process and provided 200mA of output current. A line regulation and load regulation is 12.6mV/V, 0.25mV/mA, respectively. And measured settling time is 1.5us in 5V supply voltage.

The underground electricity distributions are significantly increased because of the urbanization accompanied by rural area developments. However, it has also been increased the safety accidents such as an electric shock around the handhole where the underground cables are connected to each other. This paper provides the base materials on the necessity to amend the installation regulation for securing the insulation and structure strength of handholds using the cast iron or fiberglass reinforced plastic. Article 137 in the judgement regulation for the Korea electro-technical regulation which is one of the installation regulations for handhole is amended and announced in 2017 by being based on the materials in this paper. It is expected to continually reduce the electric shock occurrence around handhole by considering the amended installation regulation.

This study examined the effects of family climate, peer support and self-esteem on children's self-regulation. The participants in this study were 369 children (M=11.78 year) who completed questionnaires regarding family climate, peer support, self-esteem and self-regulation. Data were analyzed means by of a Structural equation model using AMOS 7.0. Our results indicated that (1) family climate, peer support and self-esteem were directly linked with children's self-regulation (2) the associations between family climate or peer support and children's self-regulation were mediated by children's self-esteem. These results imply that family climate and peer support are important antecedent variables in predicting children's self-regulation as well as their relative levels of self-esteem.
