Effect of transformed ferrite content on the mechanical properies of dual-phase steels has been studied and analyzed on the basis of observation on the austenite-to-ferrite transformation behavior during post-anneal cooling. Various contents of transformed ferrite were obtained by changing intercritical annealing temperature. As the transformed ferrite content was increased up to about 40%, dual-phase properties became better due to the finer distribution of martensite particles. However, the dual-phase properties were deteriorated when the transformed ferrite content becomes larger than the retained ferrite content. The significance of these results is discussed in relation to the austinite-to-ferrite trans formation behavior during intercritical annealing.

음주문화를 통한 <翰林別曲>의 일고찰

In Tang dynasty, popular customs from the countries bordering on western China, Buddhism music and dances, and cultures from China are combined to develop luxurious drinking culture that centralized by courtesans. Also the combination of culture and customs makes drinking rules to be more with music and dancing. The Silla nobility accept the new drinking rules and apply them to their feasts. It can be proved with the 14-sided dice from Anapji Pond. Jwajumunsaengyeon(座主門生宴: the background of <Hanrim Byeolgok>), is based on gwageo, the highest-level state examination during the Gwangjong era in Goryeo dynasty. It has various types such as Youngchinhoei(榮親會), Myungjokhoei(名簇會), Banghoei(榜會), Yongdoohoei(龍頭會), Poomjung(品呈), and so on. In those feasts, the civil official in Goryeo dynasty enjoyed the games with drinking rules using the themes of <Hanrim Byeolgok> and heightened the conviviality. <Hanrim Byeolgok> is produced by many people and has hierarchical characteristics like a troll. It belongs to ‘words characteristic’, one of drinking rules and borrows the way(Chaksaryeng: 著辭令) that fills in the names of related topics with prior consultation and consistently arranges them. However, it is thought that the arrangement of the subject seems to be changed consistently and the stories of drinking rules in the structure and historical stories of <Hanrim Byeolgok> are confirmed to follow the same arrangement. Therefore, it is possible to infer that <Hanrim Byeolgok> is completed with re-arrangement of subjects of various drinking games in Jwajumunsaengyeon in 250 years. But it is hard to find its identification in future generation due to the settlement of lyrics and severance of drinking rules. To conclude, <Hanrim Byeolgok> is the collection of various drinking game pieces in Jwajumunsaengyeon made by the Chaksaryeng way and the song with lyrics but it is difficult to call a drinking game itself.

These days, digital forensic technologies are being used frequently at crime scenes. There are various electronic devices at the scene of the crime, and digital forensic results of these devices are used as important evidence. In particular, the user's action and the time when the action took place are critical. But there are many limitations for use in real forensics analyses because of the short cycle in which user actions are recorded. This paper proposed an efficient method for recovering deleted user behavior records and applying them to forensics investigations, then the proposed method is compared with previous methods. Although there are difference in recovery result depending on the storage, the results have been identified that the amount of user history data is increased from a minimum of 6% to a maximum of 539% when recovered user behavior was utilized to forensics investigation. 최근 디지털 범죄 수사는 많은 범죄 현장에서 사용되고 있다. 범죄 현장에서는 다양한 전자 장치가 존재하며, 이러한 장치의 디지털포렌식(Digital Forensics) 결과는 중요한 증거로 사용된다. 특히, 디지털포렌식에서 사용자의 행동과 해당 행동이 발생한 시간은 매우 중요한 정보이다. 하지만 사용자의 행동이 기록되는 주기가 짧은 한계점을 가지고 있다. 이러한 특징은 실제 디지털포렌식의 제한 요소로 작용한다. 본 논문에서는 삭제된 사용자 행동 레코드를 복구하고 이를 디지털포렌식에 적용하였으며, 이전 조사 방법과 차이점을 비교하였다. 스토리지에 따라 복구 결과에는 차이가 존재하지만 복구 된 사용자의 동작이 디지털포렌식에 활용 될 때, 사용자 행위 기록이 최소 6%에서 최대 539%로 증가하는 결과를 보여준다.

청소년 국토순례 참가자의 대인관계성향, 자아탄력성 및 자아성취감에 미치는 영향

김동건 한국스포츠엔터테인먼트법학회 2017 스포츠와 법 Vol.20 No.4

The purpose of this study was to examine the effect on interpersonal relationship disposition, self-resilience, and self-achievement of adolescent participants in cross-country trip. The expression disposition and social relationship disposition were found to have a significant effect on self-achievement, regarding the effect of interpersonal relationship disposition on self-achievement. The interpersonal relationship disposition was found to have a significant effect on expression disposition, role disposition, and social relationship disposition in connection with the effect of interpersonal relationship disposition on self-resilience. Meanwhile, self-resilience was found to have a significant effect on positive future orientation, diversity of interest and attention, and emotion control in relation to the effect of self-resilience on self-achievement. Those results suggest that adolescents tend to attempt to make self-expression properly in order to maintain amicable interpersonal relationship with others during their participation in cross-country trip. In other words, they attempted to remember the praises shown by others to them and avoided prejudice, if possible, and tended to try to understand others in their interpersonal relationship. Moreover, they articulated their opinions clearly to express themselves and engaged themselves in behaviors attracting the attention of others, and attempted to seek compromise rather than conflict. Particularly, in connection with the effect of self-resilience on self-achievement, adolescents strived to have hopeful and optimistic view of their future, made efforts to achieve goals, took on challenges with interest towards various experiences and amusing things, and exhibited patience in the face of difficulties, and maintained calmness through emotion control. It would be necessary for government ministries related to adolescent affairs to proceed vigorously with policies and programs conducive to promoting various physical activities and sports activities designed for adolescents. In addition, relevant organizations would need to play supervisory role thoroughly in verifying safety educations or programs and making sure that professional manpower is secured. 본 연구는 청소년 국토순례 참가자의 대인관계성향, 자아탄력성 및 자아성취감에 미치는 영향을 알아보는데 있어서 대인관계성향이 자아성취감에 미치는 영향에서는 표현성향과 사회적관계성향이 유의한 영향을 미치는 것으로 나타났고, 대인관계성향이 자아탄력성에 미치는 영향에서는 표현성향, 역할성향, 사회적관계성향에서 유의한 영향을 미치는 것으로 나타났으며, 자아탄력성이 자아성취감에 미치는 영향에서는 긍정적미래지향성, 흥미와관심의다양성, 감정조절이 유의한 영향을 미치는 것으로 나타났다. 이러한 결과로 보았을 때 청소년들은 국토순례에 참가하는 동안 타인과의 원활한 관계유지를 위해서 자기표현을 적절하게 하려는 경향으로 보인다. 즉, 대인관계에 있어서 상대방의 칭찬을 기억하거나 가급적 편견을 가지려고 하지 않았으며, 다른 사람을 이해하려고 하는 것으로 나타났다. 또한 자기를 표현함에 있어서 자기의 의견을 잘 설명하고, 주목을 받기 위한 행동을 자주하며, 분쟁보다는 타협하기위해 노력을 하는 것으로 나타났다. 특히 자아탄력성이 자아성취감에 미치는 영향에서는 자기의 미래를 희망과 긍정적으로 생각하고 목표에 대한 노력을 하고, 다양한 경험과 흥밋거리에 대해 관심을 가지고 도전을 하며, 어려운 부분에 있어서 인내심을 발휘하고 감정조절을 통해 침착함을 유지하는 것으로 나타났다. 청소년과 관련된 정부부처에서는 청소년들에게 다양한 신체활동 및 스포츠활동을 활성화 시키는 정책과 프로그램을 활발하게 펼쳐야 할 것이며, 관련기관에서는 안전교육이나 프로그램 검증과 전문인력이 확보되었는지 등에 대한 관리감독을 철저히 해야 할 것이다.

멸종위기종인 꼬마잠자리의 부화율을 5개의 온도조건($10,\;15,\;20,\;25,\;30^{\circ}C$)에서 조사하였다. 꼬마잠자리의 알은 2006년 7월 경상북도 문경시 일대의 한 작은 습지에 서식하는 암컷 성충으로부터 채취하였다. 부화율은 100일 동안 부화한 유충의 수로부터 구하였다. 꼬마잠자리의 알은 20, 25 및 $30^{\circ}C$의 온도조건에서 각각 83, 89 및 76%가 부화하였으며, $10^{\circ}C$와 $15^{\circ}C$에서는 실험기간동안 부화하지 않았다. 꼬마잠자리 알의 부화 임계온도는 $14.3^{\circ}C$로 추정되었으며, 다른 온대성 잠자리류보다 상대적으로 높았다. The hatching rate of the eggs of Nannophya pygmaea Rambur, an endangered dragonfly species in Korea, was experimented in different temperature conditions ($10,\;15,\;20,\;25,\;and\;30^{\circ}C$) in laboratory. N. pygmaea eggs were collected from female adults inhabited a small wetland in Mungyong-si, Kyeongsangbuk-do, Korea, in July 2006. The hatching rate was evaluated from the number of hatched nymphs for the period of 100 days. As a result, the hatching rates were 83, 89, and 76% at $20,\;25,\;and\;30^{\circ}C$, respectively; however, eggs were not hatched at $10^{\circ}C\;and\;15^{\circ}C$ during the experiment period. The derived thermal threshold for egg hatching was $14.3^{\circ}C$, which is relatively higher than the values of other temperate dragonflies.

Changes of silk fibroin molecular weight was studied by enzymatic proteolysis and reverse reaction of enzymatic proteolysis (plastein reaction) using chromatography, X-ray diffraction and thermal analysis methods. When the treatment of enzymatic proteolysis with α-chymotripsin to silk fibroin solution, a precipitate of Fcp fractions was formed. And, this was dissolved in LiBr aqueous solution, the precipitate of PIFcp fractions was obtained again. Fcp and PIFcp fractions showed silk II and silk I type structure, respectively. Fcp fractions was about 6,900 in molecular weight PIFcp fractions obtained by plastein reaction on the precipitate of Fcp fractions increased molecular weight to about 15,000. The molecular weight of Fcp fractions was increased by plastein reaction, but Fcp fractions almost transited to silk I type crystal. The structure of silk I type of PIFcp fractions was steady identified by X-ray diffraction and thermal analysis. As molecular weight of Fcp fractions was gradually low, PIFcp fractions was become to macromolecule little by little.

법규적 효력을 갖는 행정규칙에 대한 소고

김동건 연세법학회 ( 구 연세법학연구회 ) 2003 연세법학 Vol.9 No.2

The Constitution declares the principle of parliamentary legislation in Article 40. But Articles 75 and 95 (and some more Articles in Constitution) permit the Administration to make legislations. on the ground of delegation. And Administration has another power of rule-making. Under the principle of “rule of law” administrative rule cannot regulate the people directly. It can only regulate the administrative office and its people directly. But sometimes the Supreme Court granted that it has the power to regulate the people directly. In that case some questions are arising. Administration rule-making procedure is different from that of Administration legislation. But the regulating power is very similar. So the Administration rule that has the regulating power must be promulgated and be open to the judgement of the court.
