GDS (Grating automatic Drawing System), which is an automatic design system of a metal product called grating, is a system that produces various detailed drawings on the basis of information within a Plan Drawing that represents layout of the grating such as locations, shapes, directions, etc. However, automatically produced drawings by GDS do not fully satisfy the standard of the general dimension marking method used among the layout designers. The lack of this standard quality mainly results from the fact that overlapping among dimension markings appear frequently. To solve the overlapping problem we applied the rule-based expert system. The rules are designed based on the expertise of skilled layout designers within the grating production lines.

Aurea helianthus (AH), a representative warm-temperature plant in southern Korea, is traditionally used in China for various medicinal purposes. The bioactive constituents from aerial parts of the AH leaf, stem, and flowers have been studied by several researchers, showing anti-inflammation, immune-modulatory, antioxidant, and whitening effects. However, the effects of the oil extracts of AH flower on the biological activities for antioxidants application have not been thoroughly investigated. This study reported the possible utilization of the oil extracts of AH flower extracts (AHF) and validated the components by GC-MS. The AHF was treated with n-hexane, chloroform, and methanol, respectively. Besides the component analysis of the extract, the antioxidant activities were determined with 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging and 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical scavenging assay. The chloroform and methanol extracts showed the highest antioxidant activities and active ingredient contents like the total phenolic and flavonoid contents. GC-MS analysis were determined to be at a maximum in the hexane extracts. In summary, The oil extracts of AHF are helpful as plant resources that can provide good antioxidants and can be used as potential natural healthy food.

증권거래법상 상법특례규정의 문제점 및 개선방안

최문희(Choi Moon Hee) 강원대학교 비교법학연구소 2006 江原法學 Vol.23 No.-

There are special provisions, applying to listed company, that are incorporated Korean Securities Act, separate from basic Korean Corporate Law. Those special provisions lead to several problems in interpreting Korean Corporate Law and Securities Act, and practical confusion in applying those provisions. First, Corporate Law is, at least in listed company, substituted for those provisions. As a result, Corporate Law has become little more than a name. Second, most of those provisions are contradictory to several provisions of Corporate Law, and their meaning is vague. Provisions on minority shareholders' rights, shareholder's proposal, appointment and removal of audit committee's members, and cumulative voting are as such. First problem may be solved, when the Coordination Act including the current Korean Securities Act be passed. In contrast, a few special provisions need to be revised or deleted to solve the second problem. For example, articles 191-14, 191-16(1) in Securities Act on shareholder's proposal and right of recommendation of candidate for outsider director should be revised. Futhermore, articles 191-11(1) and 191-17(2) in Securities Act on appointment of member of audit committee need to be deleted.

본 연구는 벽화라는 아이템이 문화관광자원으로서 활용 될 수 있는 방안을 살펴보고자 시작되었다. 소프트하고 성숙한 사회를 지향하는 한국사회에서 벽화작업이 지역정체성을 확립하고 대중과 소통하는 문화적 매체로서 어떠한 긍정적인 요소를 가지고 있는지 탐색적 차원에서 정리하였다. 벽화는 시민 모두의 소유로 자연스런 도시 환경에 알맞은, 합목적성을 지닌 의도와 계획으로 대중과의 정서적 공감대를 이룰 수 있도록 제작되어야 한다. 연구방법으로는, 이론적 분석은 유사 논제에 관한 선행연구와 국내 외 문헌조사와 인터넷 자료를 병행 하였다. 그리고 공공디자인, 문화관광, 관광학 이론 등의 관련 학문 연구를 참고하여 조사하였다. 연구범위로, 문화관광을 단순히 미술관과 박물관 관람의 차원을 떠나서 관광자가 관광체험을 통하여 만나는 모든 체험대상이 문화적 요소로서 문화관광에 해당된다고 보았다. 따라서 벽화를 관광자원화 할 수 있는 디자인적. 문화적 요소로 보고 국내외 사례를 조사하였다. 캐나다의 슈메이너스라는 작은마을이 세계적인 벽화마을로 알려지면서 관광객에게 볼거리를 제공하고 예술작품이 추가되면서 예술마을로 자리잡은 것은 벽화작업이 어떻게 문화 관광자원으로서 성공적으로 자리매김 할 수 있는지 보여주고 있다. 결론적으로, 문화관광 거리의 조성방안에 관하여 공공디자인(주민참여 커뮤니티 아트)과 도시재생적(공사장 방진막, 안전팬스, 상업적 옥외디자인 등) 차원의 벽화를 문화관광 자원으로 제안하였다. 지역 벽화작업은 지역의 발전이라는 측면과 지역 이미지, 고유성을 만들어가는 문화 관광전략적 과정이라고 볼 수 있다. The task of this research, a look at the domestic and overseas mural paintings look at the the item you want to be able to be used as culture and tourism resources began in the mind. And mature-oriented society soft-wall action in Korea to establish the identity of the region to communicate with the public as a cultural media, to have any positive element research was in the cleanup. Both paintings belong to the citizens in the urban environment as a natural right, with the intent and plan availability correspondence emotional bond with the public should be designed to achieve. Research methods, theoretical analysis of previous research on similar topics, and domestic investigations and other internet resources literature were parallel. And public design, cultural tourism and tourism-related academic research and the theory of reference were to investigate. To a range of research, cultural tourism, museum visits and art galleries just leave the dimensions of the tourism experience through self-tour experience to meet all the cultural elements as a cultural tourism destination that saw said. This mural can be designed by human resources in tourism. Study international examples of cultural elements was reported. Canada`s small village `Shemainus` the world known as a mural of the town and tourist attraction to add art to the village nestled in the mural art culture and tourism resources, as do the task successfully has become a can. This research is based on the cultural resources of this region as a tourism resource to have a mural work in the development of value based on the data collection process required for the purpose of navigation is in progress.

합병, 주식교환, 주식이전 등 조직재편과 대표소송의 원고적격의 쟁점 -대법원 판례에 대한 비판적 고찰과 입법론적 제안-

최문희 ( Moon Hee Choi ) 한국상사판례학회 2016 상사판례연구 Vol.29 No.3

주지하듯이 오래 전부터 대법원 판결은 주주가 주식을 전혀 보유하지 않게 된 원인이 자발적이든 비자발적이든 불문하고 주주는 대표소송의 원고적격을 상실한다고 보고 있다. 그런데 상법상 합병, 삼각합병, 주식교환·주식이전의 조직재편 과정에서 소멸회사, 완전자회사의 주주가이들 회사의 주식을 전혀 보유하지 않게 되고, 존속회사, 존속회사의 모회사, 신설회사, 그리고 완전모회사의 주식을 보유함으로써 구회사 주주의 지위를 상실하는 것이 예정되어 있다. 이 경우에 구회사 주주가 구회사의 이사를 상대로 제기한 대표소송의 효력이 문제될 수 있다. 나아가 구회사의 주주들이 아직 대표소송을 제기하지 않았다면 신회사의 주주가 된 이후에 구회사 이사를 상대로 대표소송을 제기할 수 있는지도 문제된다. 최근에 외환은행과 하나금융지주회사의 주식교환에 따라 구회사 인외환은행의 주식을 보유하지 않게 된 주주가 제기한 주주총회결의 하자소송을 다룬 사안에서, 대법원 2016. 7. 22. 선고 2015다66397 판결은 주식교환이 있는 경우 구주주는 구회사 주식을 전혀 보유하지 않기 때문에 원고적격을 상실한다고 판시하였다. 주주가해당 회사의 주식을 전혀 보유하지 않는 경우에는 원고적격을 상실한다는 기존의 법리를 확인한 것이다. 이 글은 조직재편 과정에서 구회사의 주주가 주식을 전혀 보유하지 않게 된 경우에 원고적격을 부정하는 대법원 법리의 타당성에 의문을 제기하고 바람직한 해결방안으로서 입법론을 모색한 것이다. 전술한 대법원판결의 법리는 도산이나 도산에 임박한 회사에서 주식을 전혀 보유하지않은 사안을 다룬 판결에서 발전된 것이다. 그러나 도산상황에서 주식가치가 전혀 없게 된 주주와 조직재편 과정에서 구회사 주주의 지위를 상실하고 신회사의 주주가 된 주주는 대표소송 수행의 이해관계가 상이하기 때문에, 양자를 평면적으로 동일하게 취급하는 것은 의문이 있다. 본론에서는 합병, 삼각합병, 주식교환·주식이전에서 주주의 대표소송 원고적격의 문제를 종합적으로 검토하였다. II에서는 주식을 전혀 보유하지 않은 주주의 원고적격의 문제, 조직재편 시 주식 미보유 주주의 원고적격의 인정 여부, 원고적격을 불인정할 경우의 문제점을 검토하였다. III에서는 조직재편에 따라 구회사의 주식을 보유하지 않고 존속회사, 완전모회사 주주가 된 경우의 원고적격의 문제를 검토한 후, 입법론적으로 이러한 경우에도 원고적격을 허용하기 위한 제도 설계를 시도하였다. 제도 설계시 고려할 사항은 원고적격의 인정범위, 주식 이외 금전등 기타 재산을 대가로 받은 구주주의 원고적격 문제, 원고주주의 주식보유 요건, 상장회사 주주의 주식보유 요건이다. Under the Korean Commercial Code(“KCC”), the plaintiff-shareholder must hold one percent of the outstanding shares in non-listed companies(Article 403(1)). For listed companies, the statutory minimum shareholding is as low as 0.01 percent, but the plaintiff need have held the shares for at least six months. Once the plaintiff has met the statutory threshold, the sale of her shares afterwards will not jeopardize her standing as long as she holds at least on share(Article 403(5)). When the plaintiff-shareholder has sold all of her shares, the derivative action becomes automatically invalid. The Korean Supreme Court(“KSC”) held that once shareholders do not hold a share, the action becomes automatically invalid. What if the would-be plaintiff involuntarily lost her status as a shareholder as a result of corporate action such as merger, consolidation, and exchange of shares? The KSC held that such a shareholder lacks standing. The KSC even held that shareholders in a parent company cannot bring a derivative action on behalf of a subsidiary, stating that the plainfiffs in a derivative action should be shareholders of the company involved, not those of its parent company. In recent shareholder resolution lawsuit case, 2015Da66397, the KSC reaffirmed that rule. It is hard to see any justification for the KSC’s decisions, since it is the highly formalistic notion. An implication of the KSC’s decision is that if X, a shareholder of A Company, brings a derivative action on A’s behalf, and A then merges into B Company, which is the survivor of the merger, X might lose standing to continue prosecuting the action, since X is no longer a shareholder in A Company. This article criticizes the rule of the KSC, and proposes revision of KCC. It proceeds as follows. Part II first starts with some impediments to bring a derivative action from the perspective of shareholders. Part III explores major issues in derivative action: standing for plaintiffs, shareholder status after Merger and Exchange of Shares.

This study was carried out to investigate the antimicrobial and antioxidative activities of Camellia japonica extracts for cosmetic applications. Antimicrobial effects of C. japonica were determined against Bacillus cereus by methanol extract of new leaf, stem and stem-leaf; Malassezia pachydermatis, by methanol extract of new leaf and stemleaf. A methanol extract of new leaf of C. japonica showed strong antimicrobial effect using paper disc method against most species especially in Staphylococcus aureus. Antioxidative activities of C. japonica seed oils were determined by DPPH and ABTS radical scavenging activities. The value of EC50 of DPPH scavenging activity was 500 mg/mL and that of ABTS scavenging activity was 96.10 mg/mL. C. japonica oil extracts showed lower antioxidative activities than those of gallic acid and α-tocopherol. Electron microscopic observation of damaged virgin hairs of different ages gave a stabilizing effects after C. japonica seed oil treatment. These results indicated that the extracts of stem, leaf and seed of C. japonica could be used as cosmetic ingredient combined with appropriate formula.

Bamboo stems extract containing porous silica has been used for medicine, food, paper and craft industry. Bamboo silica is known to support absorbing essential minerals such as calcium, potassium, and magnesium in skin, nail and hair. In this study, extract of domestic bamboos containing silica from two species of Phyllostachys nigra var. Enonis Stapf. and Phyllostachys bambusoides was prepared to prepare the bamboo silica materials. Physicochemical properties have been determined with XRD, FT-IR, FE-SEM and EDX. In addition, enzyme inhibition assay of collagenase and elastase has been performed. Phyllostachys nigra var. Enonis Stapf. silica (PNS) and Phyllostachys bambusoides silica (PBS) inhibited collagenase with IC50 value of 174.14 μg/mL and 292.60 μg/mL, respectively. While, positive control groups of retinol and α-tocopherol were shown to be IC50 values of 49.43 μg/ mL and 63.70 μg/mL, respectively. Furthermore, PNS and PBS elastase inhibition rate was 179.46 μg/mL and 377.03 μg/mL. These results suggest that PNS and PBS could be used as a candidate for anti-wrinkle new cosmetic ingredients.
