액티브 패킷은 기존의 IP 패킷과는 달리 목적지가 아닌 중간의 액티브 노드에서 실행되어야 할 필요가 있다. 이를 위해서는 하나의 프로그램을 수행하기 위한 액티브 패킷들이 같은 액티브 노드를 경유해야함은 물론이고 모든 패킷들이 손실 없이 도착해야 정상적인 작업을 수행할 수 있다. 본 논문에서는 하나의 액티브 프로그램을 수행하는데 필요한 액티브 패킷들이 손실 없이 같은 액티브 노드를 거쳐 실행될 수 있는 액티브 엔진을 제안한다. 제안한 액티브 엔진은 기존의 IP 망에 적용이 쉽고 송신자가 네트워크 내의 액티브 노드의 위치를 몰라도 액티브 패킷들이 같은 액티브 노드를 경유할 수 있으며 신뢰성 있는 액티브 패킷의 전송을 보장한다. 또한 시뮬레이션을 통하여 기존의 전송 프로토콜들과 성능을 비교ㆍ분석한 결과, 제안하는 액티브 엔진은 전송지연이 작고 처리율이 높다는 것을 확인할 수 있었다. The active packets unlike traditional IP packets should be executed at each active node along their path. To execute the active program at each active node, the active packets for an active program should go through the same active nodes and all packets are delivered without any loss. This paper presents the new active engine for every active packet which execute an active program to be routed through the same intermediate active nodes and to be delivered reliably. Proposed active engine requires fewer changes to existing IP protocols and guarantees the reliable delivery of the active packets. Moreover, even if the sender does not have any information about the intermediate nodes every active packet is routed through the same intermediate active nodes. The simulation results show that proposed active engine achieves an efficient transmission with high data delivery and low communication overhead compared with the other existing transmission protocols.

Competency-based medical education (CBME) is an outcome-oriented curriculum model for medical education that organizes learning activities and assessment methods according to defined competencies as the learning outcomes of a given curriculum. CBME emerged to address the accountability of medical education in response to growing concerns about the patient safety in North America in the 1970s, and the number of medical schools adopting CBME has dramatically increased since 1990. In Korea, CBME has been under consideration as an alternative curriculum model to reform medical education since 2006. The purpose of this paper is three-fold: (1) to review the literature on CBME to identify the challenges and benefits reported in North America, (2) to summarize the process and experiences of planning and implementing CBME at Inje University College of Medicine, and finally (3) to provide recommendations for Korean medical schools to be better prepared for the successful adoption of CBME. In conclusion, one of the key factors for successful CBME implementation in Korea is how well an individual school can modify the current curriculum and rearrange the existing resources in a way that will enhance students' competencies while maximizing the strengths of the school's existing curriculum.

본 연구는 중학생의 정서조절능력, 공격성, 스마트폰 중독의 관계를 살펴보고 정서조절능력과 스마트폰 중독의 관계에 대한 공격성의 매개효과를 검증하고자 하였다. 이를 위하여 서울, 경기 및 충청 지역에 거주하는 중학생 총 803명을 대상으로 자료를 수집하여 살펴보았다. 분석결과를 살펴보면, 정서조절능력은 공격성의 하위변인인 외현적 공격성, 관계적 공격성, 스마트폰 중독과 모두 부적 상관, 공격성의 하위변인인 외현적 공격성, 관계적 공격성은 각각 스마트폰 중독과 정적 상관을 나타냈다. 이렇듯 변인들 간에 유의미한 상관을 나타내며 이론적 배경을 통한 연구모형의 적합도 지수가 양호하였다. 또한 회귀분석 결과 정서조절능력은 스마트폰 중독에 유의미한 부적 영향을 공격성의 하위변인인 외현적 공격성, 관계적 공격성은 각각 스마트폰 중독에 유의미한 정적 영향을 미치는 것으로 나타났다. 하지만 구조방정식 검증 결과 공격성의 하위변인인 외현적 공격성과 스마트폰 중독의 경로가 통계적으로 유의미하지 않은 것으로 나타나며, 정서조절능력과 스마트폰 중독의 관계에서 공격성의 하위변인인 관계적 공격성만이 매개효과를 나타내는 것으로 확인되었다. 남·녀 성별에 따른 연구모형의 타당성을 알아보기 위해 다집단 분석을 실시한 결과, 정서조절능력이 공격성의 하위변인인 외현적 공격성에 미치는 영향에서만 남학생이 여학생보다 크게 유의미한 차이가 나타났다. 이상의 연구결과들을 통하여 본 연구의 의의를 논하였으며, 후속 연구를 위한 제언을 정리하여 마무리 하였다. This study aimed to investigate the relationships of middle school students emotion regulation ability, aggression, and smart phone addiction and to examine the mediating effect of aggression on the relation between emotion regulation ability and smart phone addiction. For this purpose, 803 middle school students in Seoul, Gyeonggi, and Chungcheong area completed. The results of this study were as follows: first, emotion regulation ability showed negative correlation with overt aggression and relational aggression, which were the subtypes of aggression, and with smart phone addiction. Also, overt aggression and relational aggression presented positive correlation with smart phone addiction. Second, emotion regulation ability had significantly negative effect on smart phone addiction while each of overt aggression and relational aggression had significantly positive effect on smart phone addiction. Third, the mediating effect of overt aggression was not significant when the emotion regulation ability s mediated aggression to examine the effect on smart phone addiction; yet, the mediating effect of relational aggression was found significant. The effect of emotion regulation ability of the male students presented significant difference on overt aggression compared with the female ones; however, the other paths did not show any significant differences. Based on the findings, the emotion regulation ability s mediated aggression to examine the effect on smart phone addiction: the mediating effect of relational aggression was found significant.

Primary biliary cirrhosis (PBC) is a slowly progressive autoimmune disease of the liver that is related to anti-mitochondria antibody and the disease is characterized by portal inflammation and immune-mediated destruction of the intrahepatic bile ducts. Several autoimmune diseases, such as hypothyroidism, Sjogren syndrome and systemic sclerosis (SSc), occur with increased frequency in patients with PBC. However, there are a few reports of a possible connection between systemic lupus erythematosus (SLE) or autoimmune hemolytic anemia (AIHA) and PBC. A 52-year-old female was admitted with fatigue and dyspnea that she had suffered with for the past month. She had suffered from jaundice for 2 weeks before admission. Many of the clinical manifestations and laboratory findings suggested the diagnosis of PBC with SSc of the limited type and AIHA. She was treated with methylprednisolone pulse therapy and ursodeoxycholic acid. We consequently diagnosed her as having SLE, as she satisfied the 4 relative diagnostic criteria-arthritis, AIHA, positive antinuclear antibody and positive antiphospholipid antibodies.

경계/탈경계의 단계별 유형화를 위한 시도-자율적 삶을 추구하는 북한이탈주민에 대한 사례연구

이 글은 `자신의 기준으로 옳고 그름을 판단하고자 하는 북한이탈 주민의 자율의지를 훼손하는 것은 무엇인가?`라는 질문을 검토한다. 북한이탈주민은 남한에서 크고 작은 성취를 통해 남한사회의 일원으로 수용 혹은 안정된 삶으로 통과하는 과정을 거치다가도 `북한에서 왔다는 것`이 문제가 되는 순간 일상의 흔들림을 겪는다. 북한이탈주민은 그 자신이 처한 구조적 위치를 자각하며 남북한 경계 사이에서 탈경계의 지점으로 미끄러져 들어간다. 그 어디에 소속되지 않아도 오롯이 온전한 사람, 외롭지만 자유롭게 되는 것이다. 경계와 탈경계를 나누는 결정적 단초는 두 문화가 자신에게 강요하는 규범을 벗어나 자신만의 기준으로 세상을 바라본다는 점에 있다. 본 연구는 자신의 기준으로 옳고 그름을 판단하고자 하는 북한이탈주민의 자율의지를 훼손하는 것은 무엇인지 살펴보기 위해 콜버그의 도덕발달 개념을 사용하여 북한이탈주민의 이야기를 분석한다. This paper examines the following question: “What is it that undermines the autonomous will of the North Korean refugees who wish to distinguish between right and wrong based on their own social criteria?” As North Korean refugees make big and small achievements in South Korea, they slowly go through the process of being accepted as a member of the South Korean society or the process of entering into a stable life. However, when their origin comes into question, their lives reel to its foundations. North Korean refugees are self-conscious of their own structural position. While they are once ambiguously situated on the margin of the two Koreas as a member of neither, at a certain point they slide into the realm of the transborder. That is, they become complete beings even without a sense of belonging to a certain group - lonely but unconstrained. The decisive factor that differentiates the marginal stage and the transborder stage is whether one sees the world by his or her own standards without conforming to the moral codes enforced by the two distinctly different cultures. The present study uses Lawrence Kohlberg`s theory of `The stages of moral development` to analyze the stories of North Korean refugees, to find out what undermines the autonomous will of these people who wish to distinguish between right and wrong based on their own social criteria.

Renal manifestations of systemic sclerosis are proteinuria, hypertension, azotemia and renal crisis. Mild proteinuria is common, but the nephrotic syndrome occurring in association with systemic sclerosis has been rarely reported. The majority of nephrotic syndrome cases are caused by glomerulonephritis in patients with an overlap syndrome of SLE and systemic sclerosis. This report suggests that the nephrotic syndrome can be an infrequent sequel of systemic sclerosis alone without glomerulopathy. A 38-year old woman was suffering from visual loss and headaches. She had Raynaud`s phenomenon and thickened skin on nearly whole body. Urine protein was 4,950 mg/day and serum albumin level was 2.7 g/dL. The result of renal biopsy was renovasculopathy-compatible with systemic sclerosis.

‘븥- + -어’의 문법화에 대한 고찰

윤보영(Yoon, Bo-Young),김인균(Kim, In-Kyun) 동남어문학회 2012 동남어문논집 Vol.1 No.33

The purpose of this paper is for studying of the function and meaning of postposition ‘beuteo’(브터) focusing on the diachronic change of ‘beuteo’. Also, for grammatical characteristics of ‘beuteo’, we tried to understand its meaning and researched on how it was recognized by comparing ‘beuteo’ and its Chinese translation in Korean annotation of Chinese literature of middle age Korean. As a result, we found that ‘NP-eulbeuteo’(NP<span style="font-family:'새굴림';"></span>브터), ‘NP-robeuteo’(NP로브터), ‘NP-beuteo’(NP브터) in Korean annotation of Chinese literature appeared differently depending on whether corresponding Chinese were recognized as lexical morpheme or grammatical morpheme. In other words, ‘beuteo’, a conjugation of ‘beut-’ and postposition ‘beuteo’ co-existed in middle age Korean, and it is appropriate to exclude ‘beuteo’ combined with relationship-indicating postpositions ‘eul/reul(<span style="font-family:'새굴림';"></span>/<span style="font-family:'새굴림';"></span>)’ from the grammaticalization process of postposition ‘beuteo’ since it is a conjugated form of predicate that differs from grammaticalization of postposition ‘beuteo’. Also, I realized that ‘NP-lobeuteo’ can be understood in its relationship with ‘NP-rosyeo’(NP로셔), and I set the grammaticalization process of postposition ‘beuteo’ by reviewing their correlation. Furthermore, by focusing on the usage of Chinese preposition appeared in original Chinese document, I studied the corresponding relationship between Chinese preposition and Korean language, and based on this study, I summarized the meaning and function of ‘beuteo’, a middle age Korean postposition.

남해안에서 주로 여름철에 어획하여 부산 및 경남 지역을 위주로 소비하고 있는 군소에서 다당류 추출을 위한 최적조건을 검토하였다. 군소 다당류 추출을 위한 단백질 가수분해 효소로는 Flavourzyme 500 MG가 가장 효과적이었고, 추출한 다당류의 회수를 위한 가장 효율적인 추출물의 농도와 ethanol 첨가량은 각각 Brix 60과 5배량이었다. DEAESepharose 칼럼 크로마토그래피로 얻은 크로마토그램상의 전기전도도와 전기영동 이동도에 근거하여 0.5~0.75 M NaCl 상에서 용출되는 물질이 GAG임을 확인하였으며, heparan sulfate인 것으로 추정하였다. 다당추출물과 정제 GAG의 uronic acid 함량은 각각 1.0 g/100 g과 6.0 g/100 g이었고, GAG를 구성하는 성분으로 지표물질인 hexosamine의 함량은 당 추출물과 정제물에서 각각 5.6 g/100 g과 25.7 g/100g이었다. 정제물은 agarose 겔 전기영동 상에서 heparan sulfate로 추정되었으며, 분자량은 겔 크로마토그래피에서 29.6 kDa으로 나타났다. The optimum condition was investigated for the extraction of glycosaminoglycan (GAG) from sea hare, Aplysia kurodai. The most effective enzyme was Flavourzyme for extraction of glycosaminoglycan. The optimum incubation temperature and time for hydrolysis were 60℃ and 15 hr, respectively. The yield of precipitated polysaccharide depended on Brix and ethanol volume. The most effective concentration of Brix and ethanol were sixty and 5 volume of ethanol, respectively. Most GAG was eluted between 0.5 M and 0.75 M NaCl gradient on DEAE-Sepharose column, and identified by electroconductivity. The contents of hexuronic acid from polysaccharide extract and GAG were 1.0 g/100 g and 6.0 g/100 g, respectively. Hexosamine of polysaccharide and GAG as indicator of GAG component was 5.6 g/100 g and 25.7 g/100 g, respectively. GAG was identified as heparan sulfate compared with bands of other GAG on agarose gel electrophoresis, and its molecular weight was 29.6 kDa on Superdex 200 HR column.
