This study deals with the participatory design process of renovating a children's park. The process should proceed with two major elements. Firstly, the children's park should be designed from the perspective of children. Secondly, it should be designed in consideration of the context of the community. This study is divided into two parts. First is the review of theory concerning the meaning and roles of the children's park as a community space, the importance of children's participation in the design and the participatory method of the children. The second is the case study. The site for the case study is Ssial Park in Nowon-Gu, Seoul. The entire process of the case study is with community participation, from identifying the park's problems to the actual construction. At every step, through the participatory programs, the community participates in the decision making. In addition, mutual understanding among participants is pursued through diverse means of communication. The following results of the case study were found. Firstly, diverse participatory programs and the active trial to enable the community to communicate contribute to the sense of ownership and responsibility concerning the park Secondly, the community can negotiate the differences in opinions without needing the help of experts. Of course, there are limits in the case study, such as the fact that the community organization, which is the core of communication and maintenance concerning the park, is not organized through the process of a case study. Another is that more diverse methods, which inform all community members of the participatory process, should have been used.

개인정보자기결정권의 효과적 보호를 위한 법적 개선책

박다영 이화여자대학교 법학전문대학원 2019 Ewha Law Review Vol.9 No.-

This paper analyzes the main differences of the data protection law of Korea and ‘General Data Protection Regulation’, which was recently legislated by the European Union. It also reviews the concept of the personal information self-determination and its constitutional grounds. Compared to GDPR, our law could be improved in terms of broadening the law’s geographical coverage, redefining the definition of ‘Personal Data’, and protecting more authority and rights of data subject. This paper is meaningful since it reviews the regulations newly enforced since May, 2018, not the European Union’s Privacy Protection Guideline which was implemented until recently and gives solutions for improving Korea’s personal information protection law. 본 논문에서는 개인정보자기결정권의 헌법적 근거를 검토한 후, 한국의 데이터 보호법과 유럽연합이 최근 제정한 ‘일반 데이터 보호 규정(General Data Protection Regulation: GDPR)’의 주요한 차이점을 분석하였다. 대한민국 헌법은 개인정보자기결정권을 명문으로 규정하고 있지는 않지만, 헌법재판소는 손가락 지문날인제도 관련 결정에서 개인정보자기결정권을 기본권으로 판시하였다. 하지만 아직까지 개인정보자기결정권과 관련된 현실적인 문제들이 실체적인 권리의 침해로 인정되지 않고, 법정 위자료 청구에 그치는 경우가 많다. 유럽의 GDPR을 참고하여 한국의 데이터보호법의 적용 지리적 범위를 넓히고, ‘개인정보’ 의 정의를 재정의하는 등의 방법으로, 보다 많은 국민의 권한과 권리를 보호할 수 있을 것이다. 본고는 2018년 초반까지 시행되던 유럽연합의 개인정보 보호지침이 아니라 2018년 5월 이후 새로 시행된 GDPR규정을 검토하고 한국의 개인정보 보호법을 개선할 방안을 연구하는 데에 의의가 있다.

Objective: Sleep behavior is modulated by serotonergic neurons within the brain, and the synthesis and release of serotonin by such neurons is thought to be influenced by the availability of tryptophan, the amino acid precursor of serotonin. Formula-feeding infants have depressed plasma tryptophan concentration relative to breast milk-feeding infants. Because tryptophan alters sleep waking patterns in adults, a study was designed to determine the difference of sleep latency relative to differences in plasma tryptophan and tryptophan : large neutral amino acid (LNAA) ratio between formula-feeding infants and breast milk-feeding infants. Method: 45 newborns who were born in Chosun University Hospital from December 2002 to December 2003 were selected. The newborns were divided to three group, 15 newborns were fed breast milk and 15 newborns were fed formula A, and last 15 newborns were fed formula B. At 6 weeks and 12 weeks, infants were sampled for measuring of serum amino acid level and tryptophan, tryptophan : LNAA ratio. And we taught infants' parents to measure sleep latency that means the time after a feeding to the first episode of active REM sleep that persist ≥ 1 min. Result: 1) At 6weeks, Serum α-amino-n-butyric acid, citrulline, tryptophan level was higher in formula A group than breastmilk group (P<0.05) and proline level was lower than breast milk group (P<0.05). In formula B group, serum n-amino-n-buryric acid, citrulline, cystine, hydroxylysine, hydroxyproline, isoleucine, leucine, lysine, methionine, phenylalanine, taurine, threonine, valine levels were higher than breastmilk group (P<0.05). And Serum isoleucine, methionine, proline, valine level were higher in formula B group than formula A group (P<0.05). 2) At 12 weeks, serum glutamic acid, methionine, ornithine levels were higher in formula group A than breast milk group (P<0.05). Serum β-alanine, aspartic acid, α-amino-n-butyric acid, ethanolamine, glutamic acid, threonine level were higher in formula B group than breast milk group (P<0.05). Serum β-alanine, ethanolamine levels were higher and arginine level was lower in formula B group than formula A (P<0.05). 3) At 6 weeks, serum tryptophan concentration and tryptophan: LNAA ratio were higher in formula A group (P<0.05). Sleep latency was 21 minutes in formula group A, 24 minutes in breast milk group, 25 minutes in formula B group but there was no statistically significance (P>0.05). 4) At 12 weeks, serum tryptophan concentration and tryptophan: LNAA ratio, time after feeding to the first episode of active REM sleep were no difference with each other group. Conclusion: There is significant difference of serum amino acids between breast-feeding infants and formula-feeding infants. And serum tryptophan and tryptophan: LNAA ratio differ between brest-feeding infants and formula-feeding infants. But there is no association between serum tryptophan, tryptophan: LNM ratio and sleep latency.

Fisetin is a bioactive flavonol molecule and has been shown to have antioxidant potential, but its efficacy has not been fully validated. The aim of the present study was to investigate the protective efficacy of fisetin on C2C12 murine myoblastjdusts under hydrogen peroxide (H2O2)-induced oxidative damage. The results revealed that fisetin significantly weakened H2O2-induced cell viability inhibition and DNA damage while blocking reactive oxygen species (ROS) generation. Fisetin also significantly alleviated cell cycle arrest by H2O2 treatment through by reversing the upregulation of p21WAF1/CIP1 expression and the downregulation of cyclin A and B levels. In addition, fisetin significantly blocked apoptosis induced by H2O2 through increasing the Bcl-2/Bax ratio and attenuating mitochondrial damage, which was accompanied by inactivation of caspase-3 and suppression of poly(ADP-ribose) polymerase cleavage. Furthermore, fisetin-induced nuclear translocation and phosphorylation of Nrf2 were related to the increased expression and activation of heme oxygenase-1 (HO-1) in H2O2- stimulated C2C12 myoblasts. However, the protective efficacy of fisetin on H2O2-mediated cytotoxicity, including cell cycle arrest, apoptosis and mitochondrial dysfunction, were greatly offset when HO-1 activity was artificially inhibited. Therefore, our results indicate that fisetin as an Nrf2 activator effectively abrogated oxidative stress-mediated damage in C2C12 myoblasts.
