Evaluation for the effect of electron-beams irradiation (0, 0.1~1 kGy) on the qualityparameters of ‘Maehyang’ strawberries (Fragaria×ananassa) were performed to verify thefeasibility of irradiation treatment as a phytosanitary treatment. Electron-beams irradiation hadnot significant effect on weight loss, moisture content, water activity and total soluble solid in bothnon-irradiated control and all irradiated samples. However, firmness were significantly reducedin a dose-dependent manner (p<0.05). Phenolic acids and hydrolysable tannins and anthocyaninscontent maintained regardless of irradiation treatment, while flavonoids of irradiated-samplesincreased than control. Moreover, 0.1~0.8 kGy irradiated samples did not show significantchanges in sensory scores for overall acceptance compared to the control. Based on these results,it is considered that suitable electron-beams irradiation of strawberry was appropriate to achievephytosanitary purpose without adversely affecting physio-chemical changes and sensory qualities.

Expression of Transforming Growth Factor-β(TGF-β) Family in Nasal Polyps and Postoperative Polypoid Mucosa after Functional Endoscopic Sinus Surgery

윤영석,최종철,장태영,정동학 대한비과학회 1997 Journal of rhinology Vol.4 No.2

Transforming growth factor (TGF)-β1, β2, and β3 are multifunctional proteins which play an important role in chronicinflammatory process, angiogenesis, and epithelial differentiation. In nasal polyps and postoperative polypoid mucosa after functionalendoscopic sinus surgery (FESS), changes of expression of TGF-β family were assessed to identify its role in formationof nasal polyps and mucosal healing after FESS. Nasal polyps and polypoid mucosa were obtained during FESS and in outpatientclinic after the surgery, respectively. Immunohistochemical staining was performed. TGF-β family was highly expressed in theepithelium, subepithelial glands, neutrophils and eosinophils of nasal polyps. On the other hand, expression of TGF-β familydecreased in the epithelium and subepithelial gland of polypoid mucosa according to a postoperative period after FESS. Theseresults suggest that TGF-β family may play an important role in formation of nasal polyps and it decreases in process of mucosalhealing after FESS.

External Nasal Appearance Preferred by Koreans:Photo Analysis

윤영석,최종철,정동학,장태영 대한비과학회 1998 Journal of rhinology Vol.5 No.2

A sound understanding of the preferred appearance of the external nose is central to successful rhinoplasty. A survey usingphotographs was conducted among college students and employees aged 20 to 39 years in Inchon, Korea. Three hundred andtwenty-one subjects filled out a questionnaire about their preferences regarding external nasal appearance. The most commonlypreferred height of the nasion, measured from the corneal plane, was 6 mm among both sexes, and the most commonly preferreddepth of the nasion, measured from the glabella plane, was 3 mm among both sexes. Regarding the nasofrontal angle, men preferredan angle of 135 degrees and women preferred an angle of 140 degrees. Men preferred a nasofacial angle of 33 degreeswhile women preferred an angle of 30 degrees. A straight nasal dorsum was most commonly preferred among both sexes andthe most commonly preferred dorsal width was 13 mm among men and 10 mm among women. The most commonly preferredtip projection was 30 mm among men and 27 mm among women and the preferred tip angle was 105 degrees among both sexes. The angle of the apex in the most commonly preferred nasal base configuration was 85 degrees among men and 70 degreesamong women. The angle of the apex in the most commonly preferred lobular configuration was 65 degrees among both sexes. The most commonly preferred ratio between nostril length and the distance from the subnasale to the tip was 45 percent amongboth sexes. The most commonly preferred angle between both nostril axes was 60 degrees among both sexes. The most commonlypreferred nasolabial angle was 90 degrees among men and 95 degrees among women. The main difference in preferencebetween Koreans and Caucasians seemed to center on the radix area rather than the tip. These results can be useful as basicguidelines for rhinoplasty.

농가의 고령화가 소득불평등에 미치는 영향 -연령효과의 실증분석을 중심으로

This study is aimed to estimate the age effect on income inequality of farm households which is resulted from the aging of farm operators and to draw out its counter-strategy through the results of this analysis. The panel generalized least squares (PGLS) method is used to examine the age effects. The data used are panel data which are from 1993 to 2011 of the farm household economy survey. The results of study demonstrate that a positive relationship exists between the age of farm operator and its relative contribution ratio to income inequality of farm households. This means that the more the age of farm operator, the more the contribution ratio to income inequality of farm households. And it also represents that relative contribution ratio of youthful farm operator to income inequality of farm households is higher than another age group.

사물인터넷 신뢰 연구와 시사점: EU FP7을 중심으로

윤영석 한국정보화진흥원 2016 정보화정책 Vol.23 No.1

The Internet of Things (IoT) is expected to provide new business opportunities by connectingdevices, persons, and their data. However, the value proposed by IoT cannot be realized withouttrust. As IoT premises on the seamless connections, it should guarantee trust among the connected persons andthings. However, there is lack of relevant discussion on how to achieve trustworthy connections and interactionsbecause most of academic studies have mainly focused on the development of IoT platforms and applications. Tofill the gaps, recent EU-funded projects such as uTRUSTit, ABC4Trust, Inter-Trust, COMPOSE, and SMARTIEhave been conducted under the FP7-ICT Framework Programme. This paper presents and discusses each project’s purpose and approach. Although their approaches aresomewhat different from each other, all of them dedicate to achieving both privacy and security by providing thetrustworthy connections. It seems to be clear that Korea also needs more academic and practical contribution interms of researches, to implement“ trust”among connected things, which will eventually satisfy what really IoT isexpected for. IoT (Internet of Things)는 기기, 사람, 이들의 데이터를 연결하여 새로운 비즈니스 기회를 제공할 것으로 예상된다. 그러나 신뢰가 결여된다면 IoT (Internet of Things)가 제안하는 가치는 달성될 수 없다. IoT는 끊임없는연결을 추구한다는 측면에서 사람, 사물과 같은 연결 대상에 대한 신뢰가 전제되어야 한다. 그러나 현재까지 진행된 IoT 연구의대부분은 플랫폼과 어플리케이션 개발에 집중되어 있어 신뢰할 수 있는 연결과 상호작용에 대한 논의는 상대적으로 부족하다. uTRUSTit, ABC4Trust, Inter-Trust, COMPOSE, SMARTIE와 같은 유럽의 FP7 ICT 연구 프로그램은 이러한 간극을 해소하고자 하는 연구들이다. 본고에서는 이들 프로젝트의 목적과 연구 방향을 소개하고 논의하였다. 각각의 연구가 취하고 있는 접근은 조금씩 상이하지만이들 연구의 공통점은 신뢰할 수 있는 연결을 통해 프라이버시와 안전을 모두 담보하고자 하는 것이다. IoT의 기대를 충족시키기 위해서는 국내에서도 연결된 사물들에 대한 신뢰 연구가 필요한 시점임은 분명하다.

국민참여재판의 위기와 개선방안

윤영석 서울시립대학교 서울시립대학교 법학연구소 2021 서울법학 Vol.28 No.4

It has been over a decade since the citizen participatory trial by jury was introduced into criminal proceedings. However, given a lot of indicators regarding the citizen participatory trial, it is a little hard to conclude that this system has accomplished a completely stable establishment. The decrease in the number of cases and the proportion of serious affairs shows the crisis of the citizen participatory trial clearly. This paper aims to examine the present status of the citizen participatory trial and point out that the fundamental cause for relevant issues comes from application-centered factors of the citizen participatory trial and court’s right to decide exclusion. It is hard to expect a dramatic change of the current citizen participatory trial as long as these two factors exist. But considering that it is too early to abolish these two entirely, this paper suggests that there is a need to adjust cases subject to the citizen participatory trial rationally, progress trials more swiftly and operate the accused-friendly judicial procedures for relieving issues, on the premise that the current system is maintained as a substitute. But it is thought that it is required to look through the citizen participatory trial all over again to operate and establish the citizen participatory trial properly. 배심원이 참여하는 국민참여재판이 형사소송에 도입된지 10년이 넘는 시간이 지났다. 그러나 국민참여재판에 관한 여러 지표를 보면, 이 제도가 완전히 안정적으로 정착하였다고 결론내리기는 다소 무리가 따른다. 사건 수의 감소 추세 및 중대사건의 비중 축소가 국민참여재판의 위기를 잘 나타내 준다. 본 논문에서는 국민참여재판의 현황의 모습을 살펴보고, 그 근본 원인이 국민참여재판의 신청주의적 요소와 법원의 배제결정권에 있음을 지적하고자 한다. 이 두 가지 요소가 현존하는 한 국민참여재판은 현재의 모습에서 극적으로 변화되기 어렵다. 다만 본고에서는 위 두 요소를 전면 폐지하는 것은 시기상조라고 판단하여, 현재의 체제를 대체적으로 유지한다는 전제에서 문제점을 완화하기 위하여 국민참여재판 대상사건을 합리적으로 조정하고, 재판을 보다 신속하게 진행시킬 수 있도록 하며, 소송절차를 피고인 친화적으로 운용하여야 한다는 점을 제안하였다. 다만 국민참여재판의 올바른 운용과 정착을 위해서는 국민참여재판 제도를 처음부터 다시 검토하는 것이 필요하다고 생각된다.

갱생보호법의 독립적 입법에 관한 재논의

윤영석 한국법무보호복지학회 2022 법무보호연구 Vol.8 No.2

보호관찰과 갱생보호는 서로 다른 목적으로 행하여지는 국가작용이다. 전자는 출소자의 감시에 초점을 맞추는 반면 후자는 출소자의 사회복귀와 사회정착을 목표로 한다. 그런데 우리나라의 경우 보호관찰 등에 관한 법률에서서로 성격이 다른 보호관찰과 갱생보호를 한데 묶어 규정하고 있다. 이는 법명으로 보아 보호관찰이 출소자 대책의 핵심이고, 갱생보호는 보호관찰을 보호하는 일에 머물러야만 한다는 것으로 읽힌다. 그러나 세계적으로갱생보호활동이 점점 중요해지는 것이 근래의 추세이다. 갱생보호가 보호관찰의 하위개념이라거나 갱생보호는 보호관찰을 방해하지 않는 선에서만 허용된다는 인식은 바람직하지 않다. 이에 이 논문에서는 다른 나라의 갱생보호 시스템을 간략히 살피고 우리나라의 옛 갱생보호법 및 보호관찰법의 내용도 검토한 다음, 현재의 법체계에 대해 비판적으로 고찰하여 보기로 한다. 특히 갱생보호에 관한 입법안도발의된 지금에 있어, 이 글이 조금이나마 올바른 출소 후 재밤방지에 도움이되었으면 하는 바람이다.
